Description

Technical Field

[0001] The invention relates to the technical field of metal waste treatment, and in particular to a metal solid waste recovery and treatment device. Background Art

[0002] Metal waste is a type of metal that has lost its original use value during processing and use. If these wastes are not properly handled, they will not only cause waste of resources but may also pollute the environment. Therefore, the metal needs to be crushed and reused through recycling and processing equipment, so that the waste metal can be converted into reusable resources and realize the recycling of resources.

[0003] At present, a patent with announcement number CN110450318B discloses an extrusion crusher, including an extrusion bin, in which extrusion rollers are horizontally arranged, drive shafts are provided at both ends of the extrusion rollers, the drive shafts are eccentrically arranged with the roller cores of the extrusion rollers, the drive shafts rotate and link the roller bodies of the extrusion rollers to move closer to or farther from the inner wall of the extrusion bin, the extrusion rollers are intermittently arranged in multiple groups, the roller cores of the multiple groups of extrusion rollers are concentrically arranged, a driving roller is provided between adjacent extrusion rollers, the driving rollers are concentric with the extrusion rollers, the outer peripheral wall of the driving rollers is provided with driving plates, and the driving plates are arranged at equal intervals along the circumference of the outer wall of the driving rollers. The scattered materials are introduced into the extrusion bin through the conveyor belt, and the driving shaft is started to rotate, thereby linking the rotation of the extrusion roller. Since the extrusion roller and the driving shaft are eccentrically arranged, the materials are brought close to or away from the inner wall of the extrusion bin, thereby realizing the operation of extruding and crushing the materials. During the deflection of the extrusion roller, the waste toy materials are abutted against the extrusion arc plate. During the deformation of the extrusion arc plate, the materials can be extruded and crushed, and the impact force of materials such as metal bolts or other metal toy-related materials on the extrusion roller can be avoided, ensuring that the above-mentioned hard parts such as the metal bolts can be smoothly guided out from the gap between the extrusion arc plate and the extrusion roller.

[0004] However, the following problems still exist in the use of the current waste crusher:

[0005] When the above-mentioned device processes scrap metal, due to the large amount of rust and dust attached to the surface of the scrap metal, it is easy to cause a lot of dust during the extrusion and crushing process. In addition, in order to ensure the efficiency of crushing when putting the scrap metal in, it is usually necessary to lean the body into the upper end of the device, and then try to place the waste in the middle position of the device. There are great safety hazards in this process, and organic oil or other impurities are likely to remain in the crushed metal waste fragments, which will then adhere to the conveyor belt, causing conveyor belt pollution, affecting the service life of the conveyor belt and the conveying effect. Summary of the invention

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1-Figure 10 The present invention provides a technical solution: a metal solid waste recycling and processing device, comprising a processing box shell 1, a driving motor 2 is arranged on the left side thereof, and the output end of the driving motor 2 is connected to a crushing roller 3 through a rotating shaft, and a fixing bracket 19 is fixedly installed at the lower end of the processing box shell 1; a first gear 4 and a second gear 5 are rotatably arranged on the right side of the processing box shell 1, a first bevel gear set 17 is coaxially arranged on the left side of the crushing roller 3, and a pulley set 30 is coaxially arranged on the first bevel gear set 17, and the pulley set 30 is coaxially connected to a conveyor belt 18, two crushing rollers 3 are symmetrically arranged front and back about the center of the processing box shell 1, and the right side of the crushing roller 3 located at the rear end of the processing box shell 1 is coaxially connected to the first gear 4, and the right side of the crushing roller 3 located at the front end of the processing box shell 1 is coaxially connected to the second gear 5, the left side of the crushing roller 3 located at the front end of the processing box shell 1 is coaxially connected to the first bevel gear set 17, and the left side of the crushing roller 3 located at the rear end of the processing box shell 1 is connected to the output end of the driving motor 2 through a rotating shaft.

[0031] When it is necessary to crush the metal waste, the drive motor 2 starts working, because the output end of the drive motor 2 is connected to the crushing roller 3 through the rotating shaft, and the two crushing rollers 3 rotate in the opposite direction under the action of the first gear 4 and the second gear 5, then the put-in metal waste can be crushed, and the crushed waste falls onto the conveyor belt 18, and because the crushing roller 3 is coaxially connected to the first bevel gear set 17, the first bevel gear set 17 starts to rotate at this time, because the first bevel gear set 17 is coaxially connected to the pulley set 30, with the rotation of the pulley set 30, the conveyor belt 18 starts to rotate at this time, so that the crushed metal waste can be transported, that is, the waste begins to be transported in the direction away from the processing box shell 1.

[0032] A fixed plate 6 is installed at the upper end of the processing box shell 1, and an electric telescopic rod 7 is fixedly installed on the fixed plate 6. A movable rack 8 is fixedly installed at the lower end of the electric telescopic rod 7. The movable rack 8 is meshedly connected with a driving gear 9, and the driving gear 9 is fixedly connected to the discharge plate 10 through a rotating shaft.

[0033] When it is necessary to put in the metal waste, the electric telescopic rod 7 starts to work, that is, the electric telescopic rod 7 starts to drive the moving rack 8 fixed at the lower end to move downward, and because the moving rack 8 is meshed with the driving gear 9, the driving gear 9 starts to rotate counterclockwise, because the driving gear 9 is connected to the discharge plate 10 through the rotating shaft, the discharge plate 10 starts to rotate, and because the discharge plate 10 rotates with the fixed plate 6 through the rotating shaft, the discharge plate 10 can be moved away from the processing box housing 1 until the discharge plate 10 rotates to a horizontal position, and the metal solid waste can be placed on the discharge plate 10 (the metal Solid waste can be placed on the edge of the discharge plate 10, and there is no need to put the body into the upper end of the treatment box shell 1 to put it in. When putting it in, the upper end of the treatment box shell 1 is shielded and protected by the discharge plate 10, which effectively improves the safety of use). Then the electric telescopic rod 7 drives the movable rack 8 to move upward. At this time, the movable rack 8 drives the driving gear 9 to rotate clockwise, that is, the discharge plate 10 also starts to rotate counterclockwise. As the discharge plate 10 tilts, the metal solid waste placed on its upper end can be unloaded. At this time, the metal solid waste slides into the middle position of the discharge plate 10, which is convenient for subsequent contact with the crushing roller 3 and is squeezed and crushed by the crushing roller 3.

[0034] An additional plate 11 is fixedly installed on the processing box shell 1, and a driving motor 12 is installed at the lower end of the additional plate 11, and the output end of the driving motor 12 is connected to the connecting gear 13 through a rotating shaft, the connecting gear 13 is meshed with the receiving gear 14, and a spray plate 15 is fixedly installed on the upper end of the receiving gear 14, a return assembly 16 is arranged on the upper end of the additional plate 11, and the return assembly 16 includes a receiving rotating shaft 161, a vortex spring 162 and a fixed sleeve 163, the receiving rotating shaft 161 forms a rotating mechanism with the additional plate 11 through a bearing installed on the additional plate 11, and one end of the vortex spring 162 is fixedly installed on the receiving rotating shaft 161, and the other end of the vortex spring 162 is fixedly installed on the fixed sleeve 163, the fixed sleeve 163 is fixedly installed on the upper surface of the additional plate 11, and the upper end of the receiving rotating shaft 161 is connected to the lower end of the receiving gear 14.

[0035] When the metal solid waste is squeezed and crushed, the driving motor 12 starts to work, because the output end of the driving motor 12 is connected to the connecting gear 13 through the rotating shaft, and the connecting gear 13 is meshed with the receiving gear 14, the receiving gear 14 starts to rotate at this time, and because the upper end of the receiving gear 14 is equipped with a spray plate 15, the spray plate 15 can be used to spray water mist in the treatment box shell 1 (the spray plate 15 is supplied with water through a water supply pipe, and the water supply pipe is connected to the wastewater circulation box, and the circulating water pipe 22 can guide the water in the cleaning box 20 into the wastewater circulation box, that is, the water can be processed and filtered through the wastewater circulation box, and the processed water enters the water supply tank through a water pump, and then is sprayed through the spray plate 15 to reduce dust), achieving For the purpose of dust reduction, as the receiving gear 14 rotates, the receiving shaft 161 installed at the lower end of the receiving gear 14 begins to rotate. Because the receiving shaft 161 is connected to the vortex spring 162, the vortex spring 162 begins to be squeezed and deformed, so that the spray angle of the spray plate 15 can be adjusted to achieve the purpose of uniform spraying. As the connecting gear 13 rotates, the connecting gear 13 no longer meshes with the receiving gear 14 (the connecting gear 13 is set as a half-tooth structure). Under the action of the vortex spring 162 restoring the deformation, the vortex spring 162 begins to drive the receiving shaft 161 and the receiving gear 14 to rotate back, that is, the spray plate 15 begins to rotate back, thereby effectively achieving the purpose of reciprocating rotation and uniform spraying.

[0036] A cleaning box 20 is fixedly installed at the lower end of the fixed bracket 19, and a cleaning plate 21 is installed inside the cleaning box 20. A flushing assembly 25 is fixedly installed inside the cleaning box 20. A circulating water pipe 22 is set through the lower end of the cleaning box 20, and a second guide roller 24 is rotatably installed inside the cleaning box 20. The second guide roller 24 and the conveyor belt 18 are in contact with each other. A first guide roller 23 is rotatably installed at the upper end of the cleaning box 20, and the conveyor belt 18 and the first guide roller 23 are in contact with each other. The flushing assembly 25 includes an extension plate 251 and a flushing spray nozzle. The flushing assembly 25 also includes an extrusion plate 253 and absorbent cotton 254, and the extrusion plate 253 is fixedly mounted on the extension plate 251, and the absorbent cotton 254 is fixedly mounted on the upper end of the extrusion plate 253, and the absorbent cotton 254 is tightly fitted to the conveyor belt 18.

[0037] As the conveyor belt 18 rotates, the conveyor belt 18 begins to enter the cleaning box 20 under the action of the first guide roller 23 and the second guide roller 24 (the height of the cleaning water in the cleaning box 20 is slightly higher than the height of the cleaning plate 21). At this time, as the conveyor belt 18 moves, the cleaning plate 21 begins to brush and clean the surface of the conveyor belt 18, and then starts to supply water to the flushing nozzle 252 (the flushing nozzle 252 is connected to the clean water tank through a water inlet pipe). At this time, the flushing nozzle 252 can be used to flush the clean water attached to the surface of the conveyor belt 18, and then the absorbent cotton 254 can be used to absorb the water stains attached to the surface of the conveyor belt 18 (the absorbent cotton 254 is slightly squeezed and fitted with the conveyor belt 18 under the action of the squeezing plate 253) to avoid the attachment of water stains and affect the subsequent conveying effect.

[0038] The second gear 5 is coaxially fixedly installed with a second bevel gear set 26, and the second bevel gear set 26 is composed of two bevel gears meshing with each other. A connecting shaft 27 is fixedly provided at the lower end of the second bevel gear set 26, and an adsorption component 28 is fixedly installed at the lower end of the connecting shaft 27. The adsorption component 28 also includes a circular plate 281 and an annular magnet 282, and the upper surface of the circular plate 281 is interconnected with the connecting shaft 27, and the annular magnet 282 is fixedly installed at the lower end of the circular plate 281. A feeding component 29 is fixedly installed at the front end position of the right side of the fixed bracket 19, and the feeding component 29 includes a collecting box 291 and a fixed scraper 292. The collecting box 291 is connected to the fixed bracket 19, and the fixed scraper 292 is fixedly installed at the upper end of the collecting box 291, and the fixed scraper 292 and the lower end of the annular magnet 282 fit each other.

[0039] As the second gear 5 rotates, the second gear 5 and the second bevel gear set 26 mesh with each other, and the second bevel gear set 26 starts to rotate. Because the lower end of the second bevel gear set 26 is equipped with a connecting shaft 27, the connecting shaft 27 starts to rotate. Because the lower end of the connecting shaft 27 is fixedly equipped with a circular plate 281, the circular plate 281 starts to rotate, and the annular magnet 282 installed at the lower end of the circular plate 281 starts to rotate, so that the iron, cobalt, nickel and the like adsorbed by the annular magnet 282 can be adsorbed and driven (the annular magnet 282 can separate the metals that can be adsorbed by the magnet). At this time, the adsorbed metal starts to be driven to rotate, and the adsorbed metal can be scraped under the action of the fixed scraper 292. As the adsorbed metal accumulates, it starts to fall into the collecting box 291 under the action of gravity (the collecting box 291, the fixed scraper 292 and the circular plate 281 are all set to non-metallic materials that are not adsorbed by the magnet), so as to separate the iron, cobalt, nickel and other metals that can be adsorbed by the magnet.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
