Description

Technical Field

[0001] The invention relates to the technical field of grinding mechanisms, in particular to a grinding device for solid waste minerals. Background Art

[0002] The development and utilization of mineral resources leaves behind a vast amount of solid waste. Most of this solid waste is hazardous. If left untreated, the hazardous factors in the waste can be transported into the aquatic environment through rainwater. Furthermore, solid waste can be introduced into the soil through human activities, causing soil pollution. Sometimes, improper storage, driven by wind, creates dust and other pollutants, harming the ecological environment.

[0003] In the process of treating hazardous solid waste, it is necessary to first determine the composition of the hazardous solid waste and pour the hazardous solid waste into a crusher for crushing. After the crushing is completed, the waste slag needs to be heated so that the lead and zinc in the waste slag at high temperature can be decomposed into oxides. The oxides are separated and purified by adding soda ash and pure acid solution, and then the waste slag and valuable elements such as lead and zinc can be recycled.

[0004] When grinding waste ore using existing equipment, dust is scattered and fragments fly around inside the machine, and the friction between the ore produces sparks. This can lead to open flames inside the machine, which can easily cause safety accidents and pose a threat to on-site workers. Summary of the Invention

DETAILED DESCRIPTION

[0029] The embodiment of the present invention provides a grinding device for solid waste minerals, such as Figure 1-7 As shown, the apparatus comprises a housing 1 with an open top and a housing 2 fixedly mounted thereon. A chamber 3 is connected to the bottom of the housing 1. Multiple mincing rollers 6 are fixedly mounted within the housing 1 and driven by a motor. The mincing rollers 6 are equidistantly spaced. A top plate 4 slidably engages within the housing 2, and a detection assembly 5 is fixedly mounted between the top of the top plate 4 and the top of the inner wall of the housing 2.

[0030] During operation, solid waste minerals are poured into the box body 1, and then the shell cover 2 is installed on the box body 1. At this time, the bottom of the top plate 4 contacts the solid waste minerals. The top plate 4 is used to limit the dust generated by the crushed minerals from floating.

[0031] A motor-driven rotating shaft 31 is hinged at the center of chamber 3. A grinding block 7 is fixedly mounted on the shaft of shaft 31. Minerals are crushed into small fragments by grinding rollers 6, which then fall into chamber 3. Shaft 31 then rotates grinding block 7, grinding the small fragments.

[0032] A hose 41 is fixedly mounted on the top of the top plate 4. Hose 41 extends outside the housing 2 and interfaces with the conveying device. The bottom of the top plate 4 has multiple recesses 42, connected to multiple water spray heads 10. The water spray heads 10 interface with the hose 41. The water spray heads 10 spray water mist, which wets the dust and further reduces dust dispersion.

[0033] The detection assembly 5 comprises a vertical rod 51, a slide 52, a thick spring 53, a reflector 54, and a laser emitter 55. The upper end of the vertical rod 51 is fixedly mounted to the top of the inner wall of the housing 2. The slide 52 is slidably engaged with the rod 51. A connecting rod 521 is welded between the bottom of the slide 52 and the top plate 4. A thick spring 53 is welded between the lower end of the vertical rod 51 and the slide 52. The reflector 54 is fixedly mounted on the top of the slide 52. The laser emitter 55 is fixedly mounted at the top of the detection assembly 5, directly above the reflector 54.

[0034] The shaft of the vertical rod 51 is inlaid with a light sensing unit 511 , and the reflector 54 is tilted at 45 degrees.

[0035] Working Principle: After the top plate 4 contacts the solid waste mineral, it moves upward, stretching the coarse spring 53. As the solid waste mineral is crushed and passes through the crushing roller 6, the top plate 4 slowly descends, and the coarse spring 53 gradually contracts, causing the slide 52 to drive the reflector 54 downward.

[0036] When the slide 52 moves to the preset position, the laser emitted by the laser emitter 55 is reflected by the reflector 54 and irradiated on the light sensing unit 511. This indicates that the solid waste minerals put into the box 1 are initially crushed.

[0037] An iron mesh cover 43 is fixedly mounted within recess 42, and showerhead 10 is fixedly mounted within the top of the inner wall of recess 42. A sliding cavity is defined within recess 42, and a rotatable shaft 44 is hingedly mounted within the cavity. Shaft 44 is driven by a motor. A curved plate 45 slidably engages within the cavity, and a wire 47 is fixedly bound between shaft 44 and curved plate 45. A thin spring 46 is sleeved around wire 47.

[0038] The arc plate 45 and the sliding cavity are both arc-shaped. One end of the thin spring 46 contacts the shaft 44, and the other end of the thin spring 46 contacts the arc plate 45. When the arc plate 45 extends from the sliding cavity, it covers the water spraying head 10.

[0039] A spring 46 ejects the curved plate 45 from the slide cavity, shielding the shower head 10. Operating Principle: The shaft 44 is rotated at a controlled rate, winding a wire 47 around it. This wire 47 pulls the shower head 10, causing it to move into the slide cavity.

[0040] A chamber is provided in the mincing roller 6, with a motor 61 fixedly installed in the center of the chamber, a piston 62 slidingly fitted in the chamber, a screw 63 welded to the drive shaft of the piston 62, and the screw 63 threadedly penetrates the piston 62, a rubber nozzle 64 is embedded in the depression on the outer surface of the mincing roller 6, and an air outlet is provided in the center of the rubber nozzle 64, the inner walls of the edges of the air outlet collide with each other, and the chamber is filled with carbon dioxide gas.

[0041] Combined with attachment Figure 6 When not in use, the rubber nozzle 64 is sealed due to the inner walls of the air outlet contacting each other. When the operator determines that dust generation is excessive, the motor 61 rotates the screw 63, causing the piston 62 to move closer to the motor 61, thereby squeezing the carbon dioxide out of the chamber. This reduces the air content within the chamber 1 and further reduces the risk of open flames. The piston 62 is a cubic block, and the chamber has a rectangular cross-section. The outer surface of the piston 62 contacts the inner wall of the chamber.

[0042] A support rod 8 is welded to the top of the top plate 4. The support rod 8 is arranged at an angle, and a striking ball 81 is welded to its upper end. A flap 9 is hinged to the top of the top plate 4, with one side of the flap 9 positioned directly below the striking ball 81. The flap 9 is driven by a motor to rotate. The rotation of the flap 9 causes the support rod 8 to bend. When the flap 9 disengages from the striking ball 81, the support rod 8 returns to its original position due to its inherent resilience, causing it to swing and strike the top plate 4 continuously. This prevents the gaps in the iron mesh 43 from being blocked by debris.

[0043] In summary, this solid waste mineral grinding device comprises a housing 1, a housing 2, and a chamber 3. Housing 2 houses a top plate 4, which presses against the solid waste minerals to limit dust dispersion. A water spray head 10 is connected to the bottom of top plate 4, spraying water mist to wet the dust and reduce dust dispersion. A motor 61, piston 62, screw 63, and rubber nozzle 64 collaborate to release carbon dioxide gas, reducing the air content within housing 1 and further minimizing the risk of open flames, thereby enhancing operational safety.

[0044] In addition, the water mist absorbs the dust and gathers into sewage, which enters the chamber 3 together with the solid waste mineral fragments. The shaft 31 then drives the grinding block 7 to rotate, and the crushed stone is immersed in water, thereby achieving the purpose of preventing the generation of open flames during grinding.

[0045] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
