Embodiment 1

[0038] The invention discloses a method for producing rubber powder using waste tires at room temperature, the steps are as follows:

[0039] a. Bead separation: use a bead separator to separate the bead ring steel wire bundle from the tire;

[0040] b. Tire crushing: Send the tires to the LP1200 tire crusher, and then to the LP800 tire crusher. After being crushed by the two-stage crusher, they are screened by the roller screening machine. Small rubber blocks with a particle size of less than or equal to 22mm are In the next process, the rubber blocks larger than 22mm are returned to the crusher for crushing and then sent to the roller screening machine, and so on;

[0041] c. Steel wire separation: Use a steel wire separator to separate the steel wire in the crushed rubber block from the rubber block to ensure that 98% of the steel wire is separated from the rubber block, and at the same time make the rubber block into rubber powder with more than 2 mesh ;

[0042] d. The ...

Embodiment 2

[0048] On the basis of embodiment 1, the more optimal technical scheme of the present invention is:

[0049] Before the bead separation step, there is also a tire sorting step: firstly remove the bias tire and semi-steel tire mixed in the all-steel radial tire, secondly take out the tire in the tire and the pad tire from the outer tire, and finally remove the accumulated tire in the tire The water is removed and the tire is allowed to dry, keeping the rim dry. There is also a tire decomposition step before the tire crushing step: the tire with the bead ring steel wire bundle removed is decomposed into more than three large rubber blocks. The steel wire after the first magnetic separation process is completely separated from the rubber particles by a steel wire separator, and the separated steel wire is directly put into storage, and a small amount of separated rubber powder is transferred to the first screening process. The fine fibers after the second magnetic separation are...

Embodiment 3

[0051] With reference to accompanying drawing 1 of specification sheet, its concrete process is as follows:

[0052] Tire sorting

[0053] 1. This production line is used to process all-steel radial tires. Among the tires purchased from outside, the mixed bias tires and semi-steel tires should be removed.

[0054] 2. Because there are tires in tires and pads among the tires purchased from outside, the tires in tires and pads should be taken out of the tires to facilitate the work of the bead separator.

[0055] 3. Remove the accumulated water in the tire, and dry the tire to ensure that the bezel is dry, which is convenient for the bead separator to work.

[0056] bead separation

[0057] The whole tire bead separator can completely separate the tire bead ring steel wire bundle from the tire, which increases the added value of the bead ring steel wire bundle. Bead ring steel wire bundles are directly put into storage, and tires without bead ring steel wire bundles enter the...

Abstract

The invention discloses a method for producing gelatine powder under normal temperature by using waste tires, which relates to the technical field of producing gelatine powder under normal temperatureby using waste rubber products, and comprises the detailed steps of: a. separating a tire bead; b. crashing the tire; c. separating steel wires; d. magnetically separating for the first time; e. screening for the first time; f. magnetically separating for the second time; g. screening for the second time; and h. screening for the third time. The method has simple technique, is convenient for large-scale industrial production, and has lower investment and production cost; the grain diameter quality of the produced gelatine powder is stable; moreover, the method can produce the gelatine powderwith different grain diameter specifications, thus meeting the demands of different users.

Description

technical field [0001] The invention relates to a method for producing rubber powder at normal temperature from waste rubber products, in particular to a process technology for producing rubber powder at normal temperature by utilizing waste and old all-steel radial tires. Background technique [0002] With the development of science and technology, automobile consumption has entered thousands of households. According to the statistics of the transportation department, the number of motor vehicles in the country has exceeded 80 million. For this reason, at least 80 million waste tires are produced in the country every year. These waste tires not only occupy a large amount of land, but also easily breed mosquitoes to transmit diseases and cause fires. In the face of piles of waste tires, the existing treatment method is to process the waste tires into reclaimed rubber powder. [0003] According to statistics, the demand for reclaimed rubber powder increased from 300,000 tons...
