[0037] Please see Figures 1 to 5The solid waste pulverizing device for environmental remediation provided by the present invention will now be described. An environmental remediation solid waste pulverizing device includes multiple reaction chambers 1 and multiple feeding mechanisms 2. Each reaction chamber 1 is equipped with a first crusher 3, a second crusher 4, a dust absorption channel 5, a metal collector 6, and a negative pressure collector 7. The feeding mechanism 2 includes a conveyor belt 21, an inclined plate 22, and a friction rotating roller 23, with one end of the conveyor belt 21 located above the corresponding reaction chamber 1. The multiple reaction chambers 1 include a first sleeve 11, a second sleeve 12 disposed within the first sleeve 11, and multiple wall plates 13. The second sleeve 12 is... The dust absorption channel 5 has multiple first openings 14 and multiple second openings 15 on the inner wall of the second sleeve 12; the first crusher 3 and the second crusher 4 are arranged at intervals, and each first crusher 3 is provided with an inclined screen 31 below it. The lower end of the inclined screen 31 is connected to the corresponding first opening 14, and the lower end of the second opening 15 is connected to the second crusher 4; the second sleeve 12 is provided with multiple guide plates 41 located between the first openings 14 and the second openings 15; the metal collector 6 and the negative pressure collector 7 are both located below the second crusher 4.

[0038] The solid waste crushing device for environmental remediation provided by this invention, compared with the prior art, involves adding waste bags to each conveyor belt 21 during operation. The waste bags abut against the side wall of the conveyor belt 21, which is located on the same side as the inclined plate 22. The waste bags are tilted onto the inclined plate 22 and, under the action of the friction rotating roller 23, are laid flat and enter the reaction chamber 1. After being crushed by the first crusher 3, the waste bags fall onto the inclined screen 31, where the crushed material is screened. The crushed material with a particle size smaller than the screen holes of the inclined screen 31 passes through the inclined screen 31, while the crushed material with a particle size larger than the screen holes of the inclined screen 31 moves downward along the inclined screen 31. The dust absorption channel 5 is then activated. The exhaust fan 51 absorbs the dust generated by the crushed waste; the crushed material falls through the first opening 14 onto the guide plate 41, and moves downward along the guide plate 41 through the second opening 15 onto the second crusher 4. The crushed material generated by the second crusher 4 and the crushed material falling from the inclined screen 31 fall together; the crushed material falls onto the metal collector 6 to collect the metal parts in the crushed material; the negative pressure collector 7 is activated to collect the crushed material without metal parts; in this way, the crushing efficiency of the first crusher 3 is improved by means of the feeding mechanism 2, and the crushing effect of the waste is improved by the double crushing and the treatment of the metal collector 6.

[0039] An annular rubber pad 17 is provided on the outer wall of the second sleeve 12. The rubber pad 17 is located above the first crusher 3 to prevent the waste bag from impacting the second sleeve 12 and causing damage to the second sleeve 12.

[0040] Please see Figure 1 , Figure 2 and Figure 5As a specific embodiment of the solid waste pulverizing device for environmental remediation provided by the present invention, a first limiting plate 24 and a second limiting plate 25 are respectively provided on both sides of the conveyor belt 21. The first limiting plate 24 is inclined and opened in the clearance notch 26; the inclined plate 22 and the friction rotating roller 23 are both provided in the clearance notch 26 and are arranged sequentially along the conveying direction of the conveyor belt 21; the inclination of the first limiting plate 24 is less than the inclination of the inclined plate 22; the rotation axis 43 of the friction rotating roller 23 is perpendicular to the conveying direction of the conveyor belt 21, and the tangential movement direction of the side of the friction rotating roller 23 near the conveyor belt 21 is perpendicular to the conveying direction of the conveyor belt 21. The conveying direction of the first crusher 21 is consistent with that of the second crusher 22; the friction rotating roller 23 guides the waste material belt from the inclined plate 22 toward the conveyor belt 21; the first limiting plate 24 and the second limiting plate 25 form a barrier around the conveyor belt 21. After the waste bag is placed on the conveyor belt 21, the waste bag tilts toward the first limiting plate 24 and abuts against the first limiting plate 24; the waste bag moves forward together with the conveyor bag, and then the waste bag is tilted onto the inclined plate 22. Under the action of the friction rotating roller 23, the length direction of the waste bag is consistent with the conveying direction of the conveyor belt 21, ensuring that the waste bag can be smoothly crushed by the two adjacent crushing rollers in the first crusher 3. The first limiting plate 24 has a small inclination angle, ranging from 10 to 30 degrees, ensuring stable movement of the waste bag under the action of the conveyor belt 21. The inclined plate 22, however, has a larger inclination angle, ranging from 60 to 80 degrees, causing the waste bag to almost lie flat on the inclined plate 22. Then, under the action of the friction rotating roller 23, the waste bag is rotated and moved from the inclined plate 22 until its length direction aligns with the conveying direction of the conveyor belt 21. A mounting frame is arranged around one side of the reaction chamber 1, with the conveyor belt 21 and the friction rotating roller 23 mounted on the mounting frame.

[0041] Please see Figure 2 As a specific embodiment of the solid waste crushing device for environmental remediation provided by the present invention, the lower end face of the inclined screen 31 is provided with a downwardly extending partition plate 32 for separating the first crusher 3 and the second crusher 4. The upper end of the partition plate 32 is fixed on the second sleeve 12 and is located below the first opening 14. The second crusher 4 is installed between the partition plate 32 and the outer wall of the second sleeve 12. The first crusher 3 is installed between the first sleeve 11 and the second sleeve 12. The second crusher 4 is located below the first crusher 3. In order to avoid the crushed material passing through the inclined screen 31 from interfering with the operation of the second crusher 4, the downwardly extending partition plate 32 is installed on the lower end face of the inclined screen 31 to divide the lower area of ​​the inclined screen 31 into two parts. One part is used for the crushed material passing through the inclined screen 31 to fall downward, and the other part is used to install the second crusher 4. The first opening 14 is located above the other part, and the second opening 15 is connected to the other part, so that the falling of the crushed material and the operation of the second crusher 4 are independent of each other and do not interfere with each other.

[0042] A portion of the area, another portion of the area, and the second sleeve 12 are arranged sequentially from the outside to the inside, so that larger particles of crushed material that have not passed through the inclined screen 31 can smoothly enter the second crusher 4 through the first opening 14, the inside of the second sleeve 12, and the second opening 15.

[0043] Please see Figure 2 and Figure 3 As a specific embodiment of the solid waste crushing device for environmental remediation provided by the present invention, the second sleeve 12 is provided with a rotating shaft 43 located above the second opening 15. One end of each of the multiple guide plates 41 is rotatably connected to the rotating shaft 43, and the other end overlaps the corresponding second opening 15. The second sleeve 12 is also provided with multiple driving components 44, which are respectively connected to the guide plates 41 to drive the corresponding guide plates 41 to rotate. The rotating shaft 43 is a frame structure, which is composed of multiple rods connected in sequence. The rods correspond one-to-one with the reaction chambers 1. The guide plates 41 are inclined and their upper ends are rotatably connected to the corresponding rods. Their lower ends are connected to the second crusher 4 through the second opening 15. Therefore, the crushed material that has not passed through the inclined screen 31 slides down along the inclined screen 31, passes through the first opening 14 and enters the second sleeve 12, then falls on the guide plate 41. Under the guidance of the guide plate 41, it passes through the first opening 14 and enters the second crusher 4. A mounting base is provided inside the second sleeve 12, located below the rotating shaft 43. Multiple drive components are mounted on the mounting base, each connected to a corresponding guide plate 41. These drive components drive the guide plate 41 to reciprocate, allowing the crushed material to fall onto different positions on the second crusher 4 according to the guide plate 41, thus ensuring uniform placement of the crushed material on the second crusher 4 and improving its crushing efficiency. A small number of ventilation holes 42 are provided on the guide plate 41.

[0044] Please see Figure 1 and Figure 2 As a specific embodiment of the solid waste crushing device for environmental remediation provided by the present invention, the inner wall of the first sleeve 11 is provided with an outwardly protruding annular cavity 16, and the first crusher 3 and the inclined screen 31 are disposed in the annular cavity 16. The annular cavity 16 increases the space inside the first sleeve 11, and the first crusher 3 and the inclined screen 31 are both installed in the annular cavity 16, so that the crushing surface of the first crusher 3 is larger, thus it can crush the waste more efficiently; and the screen surface of the inclined screen 31 is also larger, so that the crushed material that meets the specifications can be screened out more quickly.

[0045] Please see Figure 2As a specific embodiment of the solid waste crushing device for environmental remediation provided by the present invention, the second sleeve 12 is further provided with a cleaning channel 46 located on the transverse support plate 45 and penetrating the transverse support plate.

The lower part of the second sleeve 12 serves as a working chamber for accommodating personnel, and a transverse support plate 45 and a climbing ladder are provided in the working chamber. A cleaning pipe is also provided in the working chamber, with the upper end of the cleaning pipe passing through the transverse support plate 45 and located on one side of the second opening 15. After the crushing operation of the second crusher 4 is completed, the personnel can climb onto the transverse support plate 45 using the climbing ladder and then clean out the residual waste on the second crusher 4 through the second opening 15 to avoid affecting the use of the second crusher 4. The residual waste can be directly placed in the cleaning channel 46 and then discharged outside the solid waste crushing device for environmental remediation.

[0046] Please see Figure 2 and Figure 4 As a specific embodiment of the solid waste pulverizing device for environmental remediation provided by the present invention, the metal collector 6 includes a collecting plate 61 and a collecting box 62, both located below the first crusher 3 and the second crusher 4.

The collecting plate 61 is inclined between the collecting box 62 and the second sleeve 12, with its lower end overlapping the collecting box 62. The collecting plate 61 is located below the inclined screen 31 and the second crusher 4. When the negative pressure collector 7 is activated, the sized pulverized material is collected by negative pressure, while metal parts in the pulverized material first fall onto the collecting plate 61 and then slide down into the collecting box 62, thus achieving the purpose of collecting metal parts. In this way, adjusting the suction force of the negative pressure collector 7 can absorb the debris but not the metal parts.

The flow pipe 72 is fixedly installed on the outer wall of the first sleeve 11 and is connected to the third opening 71. An exhaust fan 73 is installed in the flow pipe 72. When using the negative pressure collector 7, the exhaust fan 73 is activated to create a negative pressure area in the flow pipe 72, thereby causing the crushed material in the reaction chamber 1 to enter the flow pipe 72 through the third opening 71 and then be discharged and collected. A baffle 74 is installed inside the first sleeve 11, covering the third opening 71. The baffle 74 has an inclined surface, with the upper end of the inclined surface inclined towards the second sleeve 12. A through hole for the crushed material to pass through is provided on the baffle 74, and the inclined surface is located directly above the collection box 62, so that the metal parts fall into the collection box 62 under the action of the inclined surface.
