Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, and in particular to an environmentally friendly solid waste crushing device. Background Technology

[0002] In the process of solid waste resource utilization, the crushing of solid waste is crucial. However, most current solid waste crushing equipment fails to meet the environmental protection requirements of solid waste treatment. On the one hand, solid waste often contains ferromagnetic metal impurities such as iron wire and metal scraps, which cause surface wear and damage to the crushing rollers due to their rigid contact with the rollers. Simultaneously, the metal impurities remaining in the crushed material reduce its purity, thus affecting subsequent recycling. On the other hand, the solid waste crushing process generates a large amount of dust, which, when released directly into the environment, not only pollutes the air but also harms human health.

[0003] Therefore, there is an urgent need for a solid waste crushing device that can solve the problems of metal impurities and dust pollution. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] This utility model discloses an environmentally friendly solid waste crushing device, such as Figure 1 and Figure 2 As shown, it includes a pretreatment structure 10, a crushing structure 20 and a collection structure 30. The pretreatment structure 10 is installed on the upper part of the crushing structure 20 by means of a tenon and mortise structure, and the collection structure 30 is installed on the lower part of the crushing structure 20 by means of a tenon and mortise structure. Bolts are installed at the joints of the tenon and mortise structures, thus forming a fully enclosed solid waste crushing device.

[0023] The upper processing structure 10 is used for screening and separating metallic impurities, such as... Figure 3 As shown, it includes a main channel 11 that vertically penetrates the pretreatment structure 10. A feed inlet 12 for discharging solid waste is located at the top of the main channel 11, and an arc-shaped recycling channel 13 is located on the side of the main channel. The pretreatment structure 10 also includes an internally mounted magnetic separator 14, which is located at the junction of the main channel 11 and the recycling channel 13, with a portion of the magnetic separator 14 protruding from the main channel 11. The end of the recycling channel 13 is a horizontally positioned interceptor wall that abuts against the magnetic separator 14. A rubber scraper pad 15 is fitted onto one end of the interceptor wall that abuts against the magnetic separator 14. A recycling conveyor belt 16 is located below the rubber scraper pad 15, and the end of the recycling conveyor belt 16 is a recycling outlet 17 located on the side wall of the pretreatment structure 10.

[0024] It should be further noted that the pretreatment structure 10 and the magnetic separator 14 are movably connected, and the magnetic separator 14 rotates counterclockwise under the action of a motor. The magnetic separator 14 contains several fixed wheels that support high-performance magnetic blocks. Under the action of the magnetic blocks, the surface of the magnetic separator generates a magnetic field region capable of adsorbing ferromagnetic substances. When metallic impurities in the solid waste fall into the main channel, they are adsorbed onto the surface of the magnetic separator by the magnetic field and follow the rotation of the magnetic separator 14 into the recycling channel 13. Finally, they are detached from the magnetic separator by the rubber scraper and the intercepting wall and fall into the recycling conveyor belt. The metallic impurities are then discharged through the recycling outlet along with the recycling conveyor belt.

[0025] The crushing structure 20 located in the middle is used for crushing solid waste, such as... Figure 4 As shown, the crushing structure 20 includes a structure box 21 and a first crushing roller 22 and a second crushing roller 23 disposed therein. The first crushing roller 22 and the second crushing roller 23 are a set of crushing rollers arranged in parallel and rotating in opposite directions. The roller shaft connecting end of the crushing roller set protrudes from one end of the structure box 21 and is connected to a drive system. The two crushing rollers are driven by the drive system to rotate in opposite directions at the same speed and torque, so as to mechanically crush the solid waste entering the crushing structure 20.

[0026] The lower collection structure 30 is used for screening and collecting the crushed material, such as... Figure 5 As shown, the internal screening plate 31 is provided with an array of screen holes. Several vibrators 32 are provided on the high side of the screening plate 31. The vibrators 32 drive the screening plate 31 to move up and down along the height direction. The bottom side of the screening plate 31 contacts the non-compliant discharge port 34 of the collection structure wall, and the non-compliant discharge port 34 is equipped with a movable baffle 35. A removable collection box 33 is provided at the bottom of the collection structure 30.

[0027] In addition, the pretreatment structure 10 has a reserved equipment area for installing a dust collection device 40. The dust collection device 40 includes a dust cylinder 41 for storing dust and a dust collection seat 42 for collecting dust. The equipment area is provided with a support wall for fixing the dust cylinder 41, and the bottom is provided with an equipment opening for installing the dust collection seat 42. The dust collection seat 42 is connected to the chamber of the crushing structure 20 through the equipment opening. This utility model also includes an electrical control box 50, which is located on the roller connection end side of the crushing structure 20 and is equipped with a drive device for connecting the crushing roller group. The electrical control box 50 is also equipped with a control terminal, which is connected to the dust collection device carried by the pretreatment structure 10, the vibrator installed on the collection structure 30, the motor and drive device via a communication cable. The control terminal adopts mature network control technology to realize real-time status detection of equipment and system and execution of operation commands, which will not be elaborated further.

[0028] The specific workflow of this utility model is as follows: Solid waste is fed into the main channel from the inlet of the pretreatment structure and falls into the crushing structure under gravity. During this process, the magnetic separator protruding from the main channel adsorbs metal impurities in the solid waste. The metal impurities follow the counterclockwise rotation of the magnetic separator into the recycling channel until the intercepting wall and rubber scraper strip the metal impurities. The stripped metal impurities fall onto the recycling conveyor belt and are transported to the recycling outlet located on the side of the pretreatment structure for further recycling.

[0029] Solid waste, after being pre-treated by magnetic separation and screening, undergoes mechanical crushing in the crushing structure. During this process, a dust collection unit connected to the crushing chamber continuously operates to collect the dust generated during crushing. The collected dust is then transported to a dust collection bin via a connecting pipe. The dust collection device is detachable for easy cleaning and storage of the collected dust.

[0030] Solid waste, after being mechanically crushed by the crushing structure, falls onto the screening plate of the collection structure. The high side of the screening plate is continuously vibrated by the vibrator. The crushed material that meets the particle size standard falls through the screen holes into the collection box at the bottom, while the crushed material that does not meet the standard slides to the non-standard discharge port. Then, the baffle can be opened to discharge the non-standard material.

[0031] In summary, the magnetic separator in the pretreatment structure of this utility model, supplemented by a recycling conveyor belt, achieves the screening and recovery of metal impurities in solid waste; the crushing structure uses a roller crushing principle to mechanically crush the solid waste; the collection structure separates and collects substandard and compliant materials via a vibrating screen plate; and the dust collection device collects and stores the dust generated during the crushing process. The pretreatment structure, crushing mechanism, and collection structure are connected as a whole by mortise and tenon joints and bolts to form a fully enclosed crushing and processing device, effectively preventing dust dispersion and noise transmission. This utility model effectively solves the problem of high dust pollution in traditional solid waste crushing devices, while simultaneously achieving the recovery of metal impurities, making it a solid waste treatment device that meets environmental protection requirements.

[0032] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
