Secondary breaker for whole waste tire

Abstract

The invention discloses a secondary breaker for a whole waste tire. The secondary breaker comprises a rack, a primary breaking chamber and a secondary breaking chamber; the primary breaking chamber comprises a first box body, a first movable cutter assembly and first fixed cutter assemblies relatively mounted on the two sides of the first movable cutter assembly are arranged in the first box body, the first movable cutter assembly comprises a first movable cutter shaft and a plurality of first movable blades mounted on the first movable cutter shaft, and each first fixed cutter assembly comprises a first fixed cutter positioning plate fixed to the inner side wall of the first box body; a plurality of first fixed blades are arranged on each first fixed cutter positioning plate, and cutter openings of the first fixed blades located on the two sides of the first movable cutter assembly are opposite in direction; the multiple first movable cutter blades and the multiple first fixed blades are arranged in a crossed manner, and a hopper is arranged on an opening in the upper end of the primary breaking chamber; a partition plate with a discharging opening is arranged between the first box body and a second box body, and a sliding way is arranged at the lower end of the discharging opening; the rack is further provided with a screening mechanism and a transmission mechanism.

Description

technical field [0001] The invention relates to the technical field of crushing machinery, in particular to a secondary crusher for whole tires of waste and used tires. Background technique [0002] With the rapid progress of human civilization and the rapid development of the automobile industry, how to effectively and reasonably deal with waste tires is a difficult problem facing the world today. Waste tires have the characteristics of low degradability, strong heat resistance, difficulty in crushing, and low reuse rate, so many waste tires are piled up for a long time. Not only does it take up a lot of land, but it is also easy to breed pests and fires, and there are certain safety hazards. [0003] At present, there is no effective treatment method for waste tires. With the depletion of energy sources, tire pyrolysis technology has been paid attention to and researched by Chinese and foreign scholars. The crushing machinery used for pyrolysis after crushing worn-out tir...

Problems solved by technology

[0004] In the prior art, the tire shredders on the market at this stage mainly have the following problems: 1. Some existing tire shredders cannot crush the whole tire, and it is necessary to pre-treat the tires before crushing the semi-finished products

2. Part of the crusher can realize the crushing of the whole tire, but it cannot guarantee the crushing effect due to the unreasonable structure of the cutter, and the same machine cannot adjust the distance between the cutters according to different crushing requirements; 3. For the primary crusher There are many secondary waste tire shredders on the market due to problems such as machine jamming, low output, and easily damaged knives. However, such shredders often adopt the mode of separating the primary and secondary crushing chambers, and use transmission equipment to realize the separation between the crushing chambers. connection, which not only increases the production cost, but also needs to provide a larger placement area
