A kind of solid waste crushing device and crushing method

Abstract

The invention relates to the technical field of solid waste treatment attachments, in particular to a solid waste crushing device and a crushing method, which have a simple structure, uniform feeding, and reduce the probability of failure; including a casing and a silo, both of which are hollow inside , the silo is connected to the top of the shell, and two groups of crushing rollers are symmetrically arranged front and back inside the shell, the left side wall and the right side wall of the shell are respectively connected with the first slag outlet and the second slag outlet, and the four corners of the bottom of the shell are Outriggers are provided, and a third slag outlet is connected to the central area of ​​the bottom of the shell; it also includes a reciprocating screw, a drive block, a cross bar, a threaded rod, a left fixed rod, a right fixed rod and a moving plate, and a third slag outlet is connected to the top of the shell. One opening, the front end of the first rotating shaft on the front side is keyed to a gear, the top of the drive block is provided with a rack meshed with the gear, and it also includes a first screen, a second screen, two sets of drive rods, two sets of springs and extrusion platen.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment attachments, in particular to a solid waste crushing device and a crushing method. Background technique [0002] As we all know, solid waste refers to the solid and muddy substances discarded by human beings in production and living activities. It is called solid waste, referred to as solid waste, including solid particles separated from waste water and waste gas. Solid or semi-solid substances that are no longer useful to the owner and are discarded are commonly referred to as solid waste. [0003] The existing solid waste crushing device includes a shell and a silo, both of which are hollow inside, and the silo communicates with the top of the shell, and two sets of crushing rollers are arranged symmetrically front and back inside the shell, and a first screen and a second screen are arranged obliquely inside the shell. Two sieves, the left side wall and the right side wall of the...

Problems solved by technology

[0003] The existing solid waste crushing device includes a shell and a silo, both of which are hollow inside, and the silo communicates with the top of the shell, and two sets of crushing rollers are arranged symmetrically front and back inside the shell, and a first screen and a second screen are arranged obliquely inside the shell. Two sieves, the left side wall and the right side wall of the shell are respectively connected with the first slag outlet and the second slag outlet, and the lower ends of the first sieve and the second sieve are respectively inserted into the first slag outlet and the second slag outlet. Slag outlet, the four corners of the bottom of the casing are provided with legs, and the central area of ​​the bottom of the casing is connected with a third slag outlet; when the existing solid waste crushing device is used, two sets of crushing rollers are driven by an external motor and two sets of gears. After driving, the two sets of crushing rollers rotate in opposite directions, and the solid waste is placed inside the silo, and the solid waste falls onto the two sets of crushing rollers, and the two sets of crushing rollers crush the solid waste. The slag outlet, the second slag outlet and the third slag outlet flow out; in the use of the existing solid waste crushing device, it is found that when in use, due to the conical shape of the hopper, it is easy to cause blockage at the hopper, and the first screen and the second sieve are still, it is easy to cause accumulation at the first sieve and the second sieve, and the use limitation is high
