Description

Combination device for manufacturing polymer composite by grinding method

The invention relates to a field of waste rubber and plastic pulverization and regeneration, and relates to a technology for processing and regenerating a rubber and plastic (including thermoplastic elastomer) composite material, in particular to an elastomer or/and a plastic milled at a normal temperature. A combination of polymer composites.

In the current technology of processing elastomers and new plastics into rubber and plastic composites, if the selected elastomer is a cured vulcanized rubber, it must be shredded or/and replasticized first; In the operation of filling the thermoplastic elastomer and the plastic material into the powder filler, the current technology adopts a high-speed stirring granule machine, or a combination machine of a pelletizer and an open mill, an internal mixer, a screw extruder, and the like. The operation is carried out under the conditions of 140 ° C or higher and the pinching force, and the powder-operating operation of the elastomer and the plastic is carried out by using these machines. This operation has dust flying due to open production, high energy consumption and efficiency of the gap operation. Low, the air is exposed to high temperature materials for a long time, which is easy to cause problems such as material degradation.

In addition, plastic products have been immersed in every aspect of life in today's society. The application of plastic film and composite film of paper, cloth and aluminum foil, leather materials in the fields of food and beverage, advertising materials, stationery, commodity packaging, etc. It is becoming more and more widespread. Plastic products, especially plastic and paper, cloth, aluminum foil and other composite film, leather materials, after being discarded and recycled by the society, the materials are often mixed, according to the original plastic varieties and paper, cloth, aluminum foil, etc. The separation of specific composite varieties is not only difficult to implement technically, but also economically. The mixed waste plastics are not separated, and only the existing hot melt extrusion granulation or high-speed stirring agglomeration regeneration method for pure or relatively pure waste plastics is used, because there are plastics and large particles with large difference in melting temperature in the materials, Non-melting impurities such as long fibers, which cause blockage, scorch, and smog in the hot melt extrusion, or may cause particles of infusible impurities in the product obtained by the high-speed stirring granulator. If the diameter is too large, the result will be the result of the quality/price or the ratio of the obtained recycled product. At present, the disposal methods of such mixed waste plastics are mainly landfill, incineration or thermal cracking, and these disposal methods cannot achieve the recycling of mixed waste plastic resources, but also have large investment, poor efficiency, serious environmental pollution, etc. An intractable ill.

The present inventors have previously proposed "a new method for making rubber and plastic composites" Chinese mainland patent application (200910168766.X), which proposes a method of grinding vulcanized rubber at room temperature, extending and transplanting to treat "thermosetting elastomers and A technical solution of a plastic or/and a thermoplastic elastomer, but this embodiment has been found to have at least two key unit devices hindering the solution in the combined device of the embodiment of the known unit device. The first one is: in the prior art, the normal temperature and fine crushing of the elastic body is currently only a grinding and grinding machine for the thermosetting elastic body, such as pulverizing the thermosetting vulcanized waste rubber such as waste tires. At the normal temperature and fine crushing operation, the prior art is mainly implemented by a grinding disc type fine crusher. Generally, the fineness of the feed is required to be in the range of 16 to 30 mesh, and the crushed material is required to have a better under the screw pushing pressure. Mobility to facilitate pressurization between the slits of the moving and static grinding discs; and the solution is to be thermoplastic (eg thermoset bombs) The material and the plastic or/and the thermoplastic elastomer are pulverized. As a result, after the material is pulverized for about 10 to 20 minutes, the material is passive between the end of the feed screw and the wall of the non-comminuted working area at the center of the moving disc. The grinding disc is heated and sticky, and the sticky material is heavily held until the machine is stopped. This proves that the matching mechanism between the feeding screw and the grinding disc of such a milling crusher cannot be applied to the heat sensitive "thermosetting elastomer and plastic or / And thermoplastic elastomer" material; the second is: the separation effect of impurities is not good, the thermosetting elastomer is smashed by the normal temperature fine crusher, and then the cyclone separator and the mechanical sieve separation operation, the total material is about 1~ 2% of the flaky non-magnetic metal impurities are difficult to remove;

It can be seen that the technical solution proposed in the above-mentioned "A New Method for Making Rubber and Plastic Composites" needs further improvement.

In the prior art, for a material which is difficult to flow at a screw pushing pressure due to a long strip shape such as thermoplastic or pellet-shaped solder, the normal pulverizing operation cannot be smoothly performed in the current grinding disc type fine crusher, and the hindered table is blocked. The view is: the material will hold the rod, that is, the problem is in the matching mechanism between the feeding screw and the grinding disc.

In addition, in the prior art, even the most successful pulverization embodiment which is regarded as a normal temperature fine crusher, that is, a 20-mesh pure tire coarse rubber powder is pulverized into a machine, and the material is obtained in a single pass to obtain a fine distribution of 40 to 200 mesh. It is commonly known as fine rubber powder products, and the product is less than 5% of the material of 100 mesh, 40% of the material of 40 mesh, most of the materials are around 60 mesh, followed by about 80 mesh; since this Since the introduction of the fine crusher in China in the early 1990s, it has not been seen how to achieve the smashing of the pole material with thermoplasticity or poor fluidity in the feeding mechanism of the existing fine crusher. Literature reports.

After technical analysis of the feeding screw, fine grinding disc and the matching mechanism of the existing grinding disc type fine crusher, it is found that the feeding screw, the fine grinding disc and the matching mechanism used at present have many defects, specifically:

1. The screw feed resistance is large, such as the Chinese mainland patent application number (03122891.7, 02106311.7, 200520098252.9), etc., in the drawings given in the specification of these applications, it can be clearly seen: the helical tooth depth of the whole screw Equally everywhere, the top of the spiral tooth of the whole screw is closely matched with the inner wall of the screw conveying pipe; this arrangement has the advantage of ensuring that the material can enter the working area of the moving and static grinding discs with high pressure, but the spiral is present. The strong friction between the extruded elastomer material and the inner wall of the conveying pipe causes the feeding to not only use more power consumption, but also causes the material to be frictionally heated before entering the grinding disc crushing working area;

2. The feed thrust is too small, such as the Chinese patent application number (03234405.8). In the drawings given in the specification, it can be clearly seen that the feed is realized only by the vertical drop of gravity of the earth. Material screw; such a setting, although there are advantages of energy saving in feeding, it is not conducive to increasing the output of a single machine;

3. The feed screw generates heat during the material conveying process, but the prior art solution does not have a device in the feed screw for how to eliminate heat or cool the heat generation, so that the material is before entering the grinding plate crushing work area. Has become hot;

4. In the middle of the moving disc, there is a convex stirring stem for guiding the flow of the material to be crushed into the grinding disc crushing working area, such as the Chinese Patent Application No. (200320118157.1), which can be clearly defined in the drawings given in the specification. It can be seen that there is a convex stirring stem distributed in the center of the moving disc in the direction of the centripetal direction; although this arrangement can eliminate the long-term stay of the material to be scraped in the gathering space, it can not avoid the material entering the moving and static grinding disc. The disadvantage of being strongly heated by friction before the smashing work area is smashed;

5. There is a bending angle at the large opening of the grinding nozzle of the grinding disc to prevent the feeding of the grinding disc, so that the feeding of the grinding disc is not energy-consuming, such as the Chinese patent application number (95240149.5), in the drawings given in the specification, it is clear It can be seen that there are 12 triangles distributed in the near-inner tangential line of the grinding disc, and there is a section of inner garden arc connecting between the triangles, and the inner arc of each section is adjacent to the adjacent long side of the triangle in the clockwise downstream direction. Forming a bending angle that hinders the feeding; such an arrangement will cause the grinding disc to feed poorly, and the inefficient energy consumption generates heat;

6. There is also a defect in the cooperation between the feed screw and the fine grinding disc. Specifically, there is a large aggregate space between the end of the screw and the moving disc; such as the Chinese mainland patent application number (96247279.4), etc., in the specification of these applications. In the given figures, it can be clearly seen that there is a large space for the material to be scrapped between the end of the screw and the moving disc. When the mill is working, this space is full of some of the feeds that are not fed in advance. The grinding disc pulverizes the old aggregate of the working area, and the old aggregate continuously rubs the surface of the center of the passive grinding disc. This situation will increase the invalid crushing power of the crusher, and secondly, it will limit the types of materials processed by the fine crusher. A fine crusher is a material that is not suitable for processing thermoplastics, because the thermoplastic material is heated and melted in the mechanical gathering space to be crushed, and the hot molten material eventually blocks the powder passage, and finally drives the feeding screw of the fine crusher. The motor is overloaded and tripped and stopped.

The shortcomings of the prior art are that only a patent application has proposed an attempt to eliminate the aggregate space existing between the end of the feed screw and the finely ground grinding disc, such as the Chinese Patent Application No. (02106311.7), the application is in its It is mentioned in the claims and the specification that the technical solution of the invention is characterized in that: "the dynamic grinding disc is provided with an inner hole, and the end of the screw enters the inner hole of the moving grinding disc"; however, the text of the application is described in the embodiment. In the drawings, the technical contents of the "moving disc is provided with an inner hole and the screw end is inserted into the inner hole of the moving disc" are not given; the application is only given in the drawings of the embodiment: The movable grinding disc is disposed on one side of the end of the screw, and is provided with a flat concave, and the end of the screw extends into the flat concave of the movable grinding disc;

There is no mention of the amount of fit clearance, material fit, etc. in the flat recess of the movable grinding disc which is further involved in the insertion of the screw end, only in the description that "there is no friction between the entire end face of the screw and the moving mill";

As those skilled in the art know, after the grinding disc type fine crusher works for a period of time, the pulverizing working tooth surface of the static and dynamic grinding disc will wear, and after the wear, the entire moving grinding disc will move toward the static grinding disc, and the whole time There will be friction between the end face of the screw and the moving mill; in the application of the 02106311.7, the follow-up matters such as the refurbishment of the grinding disc and the grinding of the grinding disc after the wear of the fixed grinding disc are also corrected. Not mentioned;

Therefore, the Chinese patent application 02106311.7 does not enable those skilled in the art to solve this problem without having to re-innovate labor.

In summary, in the prior art, the normal temperature fine crusher of the elastomer exists: the material has a large amount of heat before entering the fine grinding disc, and the thermoplastic elastomer cannot be pulverized, and the granules are not smashed in a match-like shape or the particles are coarse. The 16-mesh thermosetting elastomer material can not handle the difficult flow material which is not easy to turn at a right angle under the screw pushing pressure, and has a higher coarse powder content in the pulverized material of the grinding disc.

For these many defects in the prior art, the industry needs technicians to systematically innovate and comprehensively improve.

The object of the present invention is to provide a combined device for manufacturing a polymer composite by using a grinding method, and further improving the combination setting of each unit machine on the basis of improving the normal temperature grinding disc type elastic fine crusher, and improving the Chinese mainland patent application number (200910168766) .X) The implementation device of the proposed technical solution enables the technical solution to be used for the production of elastomers or/and plastics or polymer composites with fillers on the basis of suitable devices. The current method has the operational defects of dust flying, high energy consumption, low efficiency and long-term air contact with high-temperature materials; it is also the technical solution proposed by 200910168766.X, which can solve the current re-processing of waste plastics, especially mixed waste plastics. The problems of low production efficiency, poor product quality and serious environmental pollution have become a feasible solution for realizing the high value and green recycling of waste plastics, especially mixed waste plastic resources.

The combination device used in the implementation of "the technical solution of the elastomer or the plastic at the normal temperature to grind the finely divided polymer to make the polymer composite" is improved, and the improvement is focused on: the selected device is currently only capable of grinding at a normal temperature.

As a result of the above technical solution, the present invention has the beneficial effects of pulverizing the "elastomer or/and plastic" material by a combination device provided with an improved normal temperature grinding disc type elastomer fine crusher, since the treated material is eliminated The end of the conveying screw of the fine crusher and the wall of the central part of the moving disc are ineffective friction, so the waste plastic and thermoplastic elastomer can pass through the disc-type elasticity at a temperature lower than the melting temperature of the material. The fine crusher completes the process of being finely divided and homogenized. Compared with the prior art, not only the existing hot melt extrusion method is avoided, but also the defects of scorch, smoke and degradation which are inevitable after the waste plastic and the thermoplastic elastomer are heated for a long time, and the present invention is also due to The infusible large particle impurities in the material are crushed, so that the infusible large particle impurities which may occur when the mixed waste plastic is regenerated and then thermally extruded are blocked or the large particles are visible on the surface of the obtained product. Problems such as impurities;

The combination of an improved elastomeric fine crusher and a closed mixing device can be used for the characteristics of waste plastics (especially composite membranes made of mixed waste plastics and paper, cloth, aluminum foil, leather recycled materials, etc. In this material, there are plastics with large difference in melting temperature and large particles and long-fiber infusible impurities. It can be mixed with rubber powder and plastic powder filler in advance, which can not only enlarge large particles, The long fibrous infusible impurities are processed into small micro-particles, short-fiber-like infusible non-blocking materials, and the powder of the thermosetting elastomer which is milled and finely processed can be finer and the powder is mixed. The filler can be filled into the interstitial space of the elastomer or/and the plastic polymer material, and the fine crusher material can be more homogenized, so that the material is finely crushed and mixed and homogenized, and then hot melted and extruded, no longer There is a defect of plugging the net; the rubber and plastic powder filler may be one or a combination of carbon black, white carbon black, clay, kaolin, calcium carbonate, wood powder, etc.;

The combination device provided with the improved elastomer fine crusher can allow the proper temperature of the material of the disc-type elastomer fine crusher to be water-containing, so that the temperature rise of the milled fine-grained material can be controlled below 100 ° C, and the fine crushing can be achieved. The frictional heat carried by the machine material can be utilized to evaporate the water, thereby reducing or avoiding the current practice of cleaning the waste plastic, centrifugal dewatering, and then drying the hot air to save energy and operating costs;

The thermosetting elastomer can be ground together with the waste plastic or/and the thermoplastic elastomer by a combination device provided with an improved elastomeric fine crusher, and the thermosetting elastomer can be made at least finer than 60 mesh at the moment when the material is overgrinded. The particles cause the plastic and the thermoplastic elastomer to become agglomerates of a plurality of primary particles of the thermosetting elastomer, that is, a sesame-like rubber and plastic composite powder (wherein: sesame is a thermosetting elastomer primary particle of 60 to 200 mesh, The sugar is a plastic, a thermoplastic elastomer; the primary particles of 60-200 mesh, wherein the fine particles are generally 70%, and the sesame-like composite powder is preferably controlled by the material.

Can support the diversity of process routes.

A high-voltage electrostatic field separator originally used for pulverizing and separating and disposing of waste electrical circuit boards (which the invention belongs to sub-assembly device V) is transplanted into the combined device of the present invention for use in waste plastics and non-magnetic metals, etc. The regeneration process of the composite membrane material of the material enables the separated non-magnetic metal to be dense in the form of the sheet-shaped sand, and the light-foamed non-magnetic metal film which is separated from the waste plastic composite film by the acid-removing process, Compared with the non-milling and pulverizing method, the plastic powder of about 40 mesh, which is still in the form of a tight composite of plastic and non-magnetic metal, can not be separated from the magnetic metal film, and has better market application, and the separation process is also better. Compared with the acid method, it saves energy, saves water and saves labor, and does not discharge waste acid and waste gas. The use of an elastomeric fine crusher equipped with the improved screw and disc matching mechanism provided by the present invention, wherein the lubricating soft filling member, after a period of work, lubricates the soft filling member to always follow the pulverizing working tooth surface of the static grinding disc. Simultaneous wear can not only keep the filler between the end of the screw and the moving disc, but also leave the space for the material to be pre-energized and statically milled, and the soft filling member can work in the mill. The minimum frictional heat is emitted, which also minimizes the inefficient pulverization power consumption of the moving disc. Lubricating soft filling members are consumables like the grinding discs. They can be replaced regularly, just like with a grinding disc. The invention provides an "improved elastic body fine screw and grinding disc matching mechanism", which is suitable for at least the improvement of the currently used flat or tapered surface-temperature grinding disc type elastic fine crusher.

The technical solutions proposed by the present invention are further illustrated by the more representative embodiments, but the embodiments should not be construed as limiting the scope of the present invention.
