Abstract
The present invention discloses a method and a device for crushing waste rubber. The present invention is characterized in that a water base crushing assisting agent is sprayed in the crushing process, a high-speed crushing head is used for a crushing device, and then, waste rubber can be crushed under the condition that the waste rubber forms friability or approximatively forms friability at room temperature by the combination of the water base crushing assisting agent and the crushing head. Thus, the energy consumption during crushing can be greatly reduced. The obtained rubber powder can be selected within a wide particle size range and can be used as directly mixed rubber powder. The present invention has the advantages of no harmful gas and fly ash generation during the crushing, good environmental protection condition, generalized device and simple processes.
Description
The present invention is a kind of breaking method and device of waste old.
Waste old generally is meant the rubber and the tailing of performance failures such as junked tire, sole, pad, sealing ring.According to investigations, the annual waste old that approximately forms 500,000 tons of China at present, has only the processing power of regeneration about 150,000 tons every year.The key that hinders disposal ability to improve is the pulverizing problem of waste old.
Before the present invention made, in the domestic production of producing reclaimed rubber, the method that waste old is pulverized mostly adopted dry method, and the device of use is the double-roll crusher of with groove.Waste old is torn in this device to be pinched and fragmentation.Concrete crushing process is: block less waste old, can cut off as sole material etc.; The waste old of bulk as damaged tire etc., cuts into the blob of viscose of tens of centimeter length, after double-roll type primary breaker, intermediate crusher fragmentation, pulverizes with the double-roll type atomizer again.In the crushing process, be dry milling, do not add entry or other liquid.The rubber powder granularity major part of producing is about 20 orders.Use this equipment, the energy consumption height, efficient is low, is difficult for obtaining the rubber powder of fine (more than 40 orders).
States such as American and Britain, day, Germany, be extensive use of the deep cooling crushing technology and carry out the pulverizing of waste old, be about to waste old and in liquid nitrogen, carry out fine pulverizing behind the deep cooling embrittlement, the rubber powder that is obtained can not only be used to produce reclaimed rubber, can also mix in the primary rubber powder and do filler, make rubber have good performance.But this method need be with a large amount of liquid nitrogen with than complex apparatus, the cost height.
In recent years, day disclosure patent of two kinds of pulverizing waste rubber.The one, the toothed disc type comminuting method of the positive husband's invention in gloomy mountain (the clear 54-87782 of Japan's special permission), it is that waste old places two between cog and pulverized by two fluted disc relative motions up and down.In the crushing process by pipeline between fluted disc continuously water flowing or air pulverize, rubber powder flows out fluted disc with water or air.This method is to be specifically designed in the pulverizing of junked tire, and adaptive surface is narrow; The discontinuous operation is difficult for realizing serialization production; The fluted disc diameter is greater than diameter of tyres, can not rotate at a high speed, and it is big that institute obtains the rubber powder granularity.
Another kind is that the water under high pressure (250～300 atmospheric pressure) that Gong Benchang controls invention sprays comminuting method (the clear 56-89538 of Japan's special permission), can obtain the rubber powder about 50 orders.But this method water consumption is big, and the equipment that obtains water under high pressure is complicated.
Task of the present invention is to seek a kind of comparatively easy method and apparatus that can at room temperature pulverize waste old.
Realize that technological approaches of the present invention is, use the tailored flour crushing device with high speed shredder head, the water base disintegrator that helps of spray carries out pulverizing under the room temperature to waste old in crushing process.
Use among the present invention water base to help the Main Ingredients and Appearance of disintegrator be water and SZ, the content of water is 95～99%(weight); The content of SZ is 1～5%(weight).Preferential scope of recommending is: water is 98%(weight), SZ is a 2%(weight).
The employed water base disintegrator SZ that helps is formulated by surface reactive material and additive among the present invention, and its component content and the preferential best component content of recommending are (all being percentage by weight):
The component content optimum content
Secondary sim alkylphenol APEO 27～35 29～30
Sodium phosphate trimer 35～47 40～42
Nekal BX J base sodium naphthalene sulfonate 7～12 8～9
Ethanol 3～7 4～5
With the formulated water base disintegrator that helps of above-mentioned composition, meet the sewage discharge requirement of national environmental protection department regulation, in use do not produce harmful substance.
The tailored flour crushing device of recommending among the present invention is by the high speed shredder head, help and pulverize the liquid shower nozzle, compress and feed mechanism, water basely help storage and the circulatory system and the rubber powder of pulverizing liquid and help the pulverizing liquid separation system to form.Adopted among the present invention three kinds can the phase trans-substitution the high speed shredder head.
Advantage of the present invention is: 1. energy-conservation.Owing in crushing process, adopted high speed shredder head and the water base disintegrator that helps of spray, can make waste old at room temperature be fragility or pulverized near brittle state, therefore, use method and apparatus of the present invention when obtaining the rubber powder of same particle sizes and equivalent amount, comparable use double-roll crusher energy-conservation 50～70%.2. the rubber powder granularity can (20～80 orders or thinner) be selected in quite broad scope, thereby can adapt to the needs of various different purposes.3. environmental protection condition is good.The water base adding that helps pulverizing liquid can make no longer to produce any pernicious gas and dust in the crushing process, helps the health and the workers'health of operation site.4. simple, the generalization of equipment can be produced continuously.Therefore, can receive favorable economic benefit and social benefit.
Below in conjunction with accompanying drawing, process chart and an embodiment, the reducing mechanism of recommending among the present invention is done one with utilization the present invention specific embodiment that enforcement is pulverized to waste old be described in detail.
Fig. 1 is waste old reducing mechanism figure.
Fig. 2 is the structure chart of the high speed shredder head 1-1 type in the reducing mechanism.
Fig. 3 is the structure chart of reducing mechanism high speed shredder head 1-2 type.
Fig. 4 is the structure chart of the high speed shredder head 1-3 type in the reducing mechanism.
Fig. 5 is a process chart.
The tailored flour crushing device (Fig. 1) of recommending among the present invention, by high speed shredder head 1, help the compression of pulverizing liquid shower nozzle 2, waste old and feed mechanism 3, water basely help storage and the circulatory system 5 and the rubber powder of pulverizing liquid and help pulverizing liquid separation system 8 to form, high speed shredder head 1, shower nozzle 2 and compression and feed mechanism 3 are installed on the pedestal 9, it is characterized in that high speed shredder head 1 can be made up of following three kinds of forms; Each other can phase trans-substitution: a, be formed by stacking 1-1 pattern (Fig. 2) by thin circular saw bit; B, combine 1-2 pattern (Fig. 3) by emery wheel; C, combine 1-3 pattern (Fig. 4) by " doffer " that use in the textile industry.
