WO1999047326A1 - Method for compacting used tyres - Google Patents

Abstract

The present invention pertains to the field of techniques for recycling industrial waste and more precisely relates to techniques for recycling used tyres. The purpose of this invention is to increase the volumetric compacting density of the materials to be recycled, i.e. the rubber and metallic cord, during the transportation and recycling processes of used tyres. To this end, the method of the present invention first comprises separating the tyres into tread and side-wall portions. The tread portions of the tyres are cut in the radial plane and wound into a spiral-shaped strip. In one aspect of this method, the spiral-shaped strip comprises a plurality of tread portions which are sequentially wound one after the other. In another aspect of this method, the side-wall portions are arranged one onto the other with the convex part on the same side so as to form a pack in the shape of a cylindrical ring.

Description

Method for compacting worn-out car lugs

Field of technology

The invention concerns the technology of industrial production, namely, the technology Repairing worn-out vehicles.

Previous level of technology

A method is known for processing worn-out car hoods with a metal casing using mechanical crushing, whereupon they are transported to the processing site, separated from the bead rings, and processed into installation with two rotating towards each other

₁₀ shafts on which the cutting elements are placed [δυ, A 1, 633601].

The disadvantage of this method is significant waste on transporting worn-out tires from the point of failure to the point folding and the place of storage before the place of waste due to the low compactness of the placement of the bulkheads sings, and also low productivity 15 mechanical crushing of caps.

There is a known method for treating worn-out cars with a metal core, using the method of bio-bleaching [δυ, Α 1, 17525622].

Therefore, the method of replacement of worn-out tires in places ₇₀ failure, maintenance and work, and Also, cooling and mechanical addition are carried out simultaneously and completely.

The disadvantages of this method are high transportation costs, large dimensions of the crushing equipment and its high energy consumption, due to the low degree of volumetric compaction.

25 crushed material in a whole layer and a low degree of compaction of the layers between themselves during their transfer.

The above-mentioned shortcomings of these methods of transport and handling make them unsuitable for handling large-sized lids of quarry dump trucks, for example. type "BelAZ" due to the influence of the large-scale factor and a sharp decrease in the efficiency of transportation and crushing of such particles. -

The closest to the proposed solution is a method of recycling worn-out roofs, in which, before transportation, the roofs are crushed or crushed and then divided into several parts using the energy of an explosion [5v, No. 1, 1614843]. - This method also involves separating the segments of the side rings from the obtained parts of the caps. The method allows achieving a higher degree of compaction of processed grains and thereby reducing the costs of their transportation and grinding.

However, the implementation of the method for the covers of large dump trucks is associated with the use of large-sized and expensive blast chambers. In addition, this method does not allow to significantly increase the degree of volumetric compaction of the processed material during its transportation.

The technical task of the invention is to increase the density of the volumetric compaction of the processed material - rubber with metal core _during the processing and recycling of worn-out roofs.

Demonstration of the invention The stated technical task is achieved by using a well-known method of compaction Automatic towers (including the division of towers into the main and combat parts) technical parts of the towers phases at ι ₀ radial planes and twist them into the form of a spiral tape.

According to a particular version of this method, after rolling the outer part of the ashes, The news of the received spy tape is crowded together and the current part of the second tower has been squished. - ⁵ According to a private version of this method, a special tape is made up of several successively intertwined arcs the other parts of the bulges are leaking.

According to a particular variant of the method, the fixation of the tape spiral shape is carried out by wire clamps 30 According to a particular variant of the method. The fixation of the tape spiral shape is achieved by placing it inside the protective part of the lid without cutting.

According to a particular method, the side parts of the towers 3

I lay the arc on the arc with the convex part in one side, folding the package in the shape of a cylindrical ring.

According to a particular variant of the method, before compacting the side parts of the hood, the side ring is removed. ⁵ According to a particular variant of the method of performing the package, it is fixed with wire twists.

Variants of implementation of the invention

Specific examples of the implementation of this method are given below.

Note 1. Produces bulk packing

₁₀ MI-16-1 (165/80K.13 825), having the following overall dimensions: outer diameter - 580 mm, inner diameter - 320 mm and width - 160 mm. Using a special application, the sides are cut out at five caps with an outer diameter of the cut ring of 420 mm. Make one radial cut in the lateral part of each cover and twist it

₁₅ flowing parts of the axle socket were fused with the help of a spool with a diameter of 350 mm. Fix the resulting fiber tape using fiber clips. On the outer surface of the spiral tape, the second part is twisted, and then the remaining three parts of the cover and the resulting spiral tape is fixed with wire staples.

- _>0 Volume of a compact package in the form of a special tape of 5 high-tech parts. Compactable according to the method we offer. is about

0.077 m3, which is approximately three times less than the volume of a package of 5 whole caps (0.21 ^m3 ).

Example 2. Five lids of the MI-16-1 type are compacted with -, ₅ dimensions as in example 1. The sides of all five lids are cut with an outer diameter of the cut ring of 420 mm. Using the cutting tool, make one radial cut in the section of the four flaps and twist them sequentially into a spiral tape as described in Example 1. The resulting spiral tape is laminated with fixatives made of

30 wires. The resulting tape is inserted into the protective part of the fifth cover without a radial cut. I remove the material and let it ring out due to its own properties of the internal sound of the song turrets and a compact package of five high-tech parts „

4 pics.

Volume of a package of 5 special parts of bulges that can be packaged in this way is 0.042.\G. which is approximately 5 times less. - than the volume of five whole units (21 m ³ ).

Example 3. Compaction is carried out of 20 side parts of covers cut from ten covers used in examples 1 and 2. Side rings are cut out from all side parts of the covers. Compaction of the guides by laying the side parts of the arc on the arc with the convex part in one side according to the “plate in” principle platter" and form a compact package of 20 barrels in the shape of a cylindrical ring. The resulting cylindrical ring with a high diameter of 640 mm is fixed using fiberglass skκρτοκ. The volume of the cylindrical ring obtained in this way is approximately 0.1 of the volume occupied by 10 Pumps.

Industrial applicability 5 Thus, the proposed method allows you to significantly increase the density of the volumetric Compacting materials from recyclable bulges. This makes it possible to significantly reduce the cost of transportation from the point of production to the place of refining, as well as Allows you to significantly increase productivity and work in the process. which are limited by 0 compaction of the processed material in the working volume of the technological equipment. When implementing the proposed method, simple equipment is used, and the process of compacting the covers consists of simple operations.
