Description

Technical Field

[0001] This utility model relates to the field of solid waste crushing technology, specifically to an industrial solid waste crushing and screening machine. Background Technology

[0002] Industrial solid waste crushing and screening is an important part of the industrial solid waste treatment process. It refers to the process of using mechanical force to crush large pieces of industrial solid waste into smaller pieces and then separating materials of different particle sizes through screening equipment. The purpose of crushing and screening is to reduce the volume of waste, lower transportation and treatment costs, and improve the recycling rate of resources, thereby achieving waste reduction, resource recovery and harmlessness.

[0003] Conventional solid waste crushing and screening machines mainly consist of a crushing mechanism and a screening mechanism. The screening mechanism is mainly composed of screens. During actual screening, the crushed material falls onto the screen for screening. Due to the limitations of the crushing box structure, most of the material falls to the middle of the screen. This not only causes excessive wear in the middle of the screen, but also increases the possibility of blockage in the middle. At the same time, the material will also adhere to the inside of the crushing box, affecting the crushing efficiency. Improvements are urgently needed. Summary of the Invention

[0004] The purpose of this utility model is to provide an industrial solid waste crushing and screening machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial solid waste crushing and screening machine, comprising a crushing box, with feed inlets fixedly connected to the top of the crushing box near the left and right sides, a frame fixedly installed in the middle of the top of the crushing box, fixed guide rails installed on the front and rear sides of the bottom of the crushing box, a screen located directly below the crushing box between the two fixed guide rails, guide blocks fixedly installed on the front and rear sides of the screen, the screen being movably engaged with the fixed guide rails through the guide blocks, the screen shifting left and right relative to the fixed guide rails, support legs fixedly installed on the left and right sides of the fixed guide rails, auxiliary screening components installed at one end of each guide block, and air inlets fixedly connected to the front and rear sides of the crushing box near the bottom.

The other end of the air supply pipe is connected to the auxiliary screening component.

[0008] As a further preferred embodiment of this technical solution, the auxiliary screening component includes a mounting frame, which is connected to one side of the crushing box, and a power tank is fixedly installed at the front end of the mounting frame.

[0009] As a further preferred embodiment of this technical solution, the top of the power tank is connected to the bottom of the air supply pipe, and the bottom of the power tank is fixedly connected to a bend, with the end of the bend away from the power tank connected to the air inlet.

Power boxes 5 are installed on both the front and rear sides of the crushing box 1. The power boxes 5 are composed of a motor and a reduction gear set, and their output ends are connected to the crushing rollers 4.

[0026] When crushing and screening, the power box 5 can be turned on to output power to multiple crushing rollers 4 and drive multiple crushing rollers 4 to rotate, so as to crush the fixed waste inside the crushing box 1. The crushed solid waste can be discharged through the bottom of the crushing box 1 and then discharged after being screened by the screen 9, thus completing the crushing and screening process.

[0027] like Figure 1 and Figure 2 as well as Figure 6 As shown, an air pump 11 is fixedly installed in the middle of the frame 3. The output end of the air pump 11 is fixedly connected to a four-way valve 12. The bottom end of the four-way valve 12 is connected to the middle of the top of the crushing box 1. Air supply pipes 13 are fixedly connected to both the front and rear sides of the four-way valve 12. The other end of the air supply pipe 13 is connected to the auxiliary screening component 14.

[0028] Simultaneously, during the crushing and screening process, the air pump 11 can be turned on to input high-pressure air into the four-way valve 12. Some of the compressed air can be discharged through the bottom of the four-way valve 12 and enter the crushing box 1, acting on the surface of the crushing roller 4 to complete the auxiliary cleaning process. At the same time, the compressed air can be discharged through the air supply pipe 13 and enter the power tank 142. The air entering the power tank 142 can enter the bottom of the crushing box 1 through the bend pipe 143 to perform auxiliary cleaning on the bottom of the crushing box 1, reduce the adhesion of material at the bottom of the crushing box 1, and improve the crushing efficiency.

[0029] like Figure 2 and Figure 6As shown, a main shaft 144 is movably connected to the middle of the power tank 142. An impeller 145 located inside the mounting bracket 141 is fixedly sleeved on the outer side of the main shaft 144. A first connecting rod 146 is fixedly connected to the front end of the main shaft 144. A second connecting rod 147 is movably connected to the end of the first connecting rod 146 away from the main shaft 144 via a rotating shaft.

The end of the mounting shaft 148 away from the second connecting rod 147 is fixedly connected to the middle of the guide block 10.

[0030] Simultaneously, when high-pressure air enters the power tank 142, it can drive the impeller 145 to rotate. At this time, the main shaft 144 rotates accordingly, driving the first connecting rod 146 to rotate. When the first connecting rod 146 rotates, it can simultaneously drive the second connecting rod 147 to rotate, and apply a leftward pulling force and a rightward pushing force to the mounting shaft 148. At this time, the screen 9 can achieve reciprocating left and right displacement under the guidance of the guide block 10 and the fixed guide rail 8, so that the screen 9 can fully contact the material, reduce the possibility of clogging, improve service life, and further improve crushing efficiency.

[0031] This utility model provides an industrial solid waste crushing and screening machine, the specific working principle of which is as follows:

[0032] When crushing and screening solid waste, the solid waste can be put into the crushing box 1 through the feed inlet 2, while keeping the screen 9 directly below the bottom of the crushing box 1. At the same time, the device needs to be fixed on a flat ground by the support legs 7 to complete the preparation before crushing and screening.
