Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically a screening equipment for crushing and recycling cyanide slag. Background Technology

[0002] Cyanide slag refers to cyanide-containing waste residue generated during the extraction of gold, silver, or other metals in mines or smelters. Cyanide slag typically contains cyanides, metal residues, and other chemicals, and this waste is highly toxic and environmentally hazardous. Specialized equipment and measures are required to handle cyanide slag to ensure that the waste does not harm the environment or human health.

[0003] In the cyanide slag recycling process, screening equipment helps separate the crushed slag into particles of different sizes for appropriate processing. The use of screening equipment improves processing efficiency, reduces energy consumption, and increases resource utilization, thereby achieving effective recycling and utilization of the waste slag.

[0004] Currently, the screens of screening equipment are easily clogged by particles during operation, which affects screening efficiency. Furthermore, some small particles and dust are released during screening, causing pollution to the external environment. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a screening equipment for crushing and recycling cyanide slag, which solves the problem of screens being easily clogged by particles, and also solves the problem of smoke and dust overflow during screening causing pollution to the external environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screening device for crushing and recycling cyanide slag, comprising a cabinet, a support plate fixedly connected to the lower end of the cabinet, a discharge port fixedly connected to the bottom of the cabinet, a feed port fixedly connected to the top of the cabinet, a box fixedly connected to the right end of the cabinet, multiple uniformly distributed screen plates slidingly sleeved inside the cabinet, a connecting rod fixedly connected between adjacent screen plates, a screening mechanism provided on the screen plates, and a dust collection mechanism provided on the box;

[0007] The screening mechanism includes a rotating shaft, which is rotatably connected to the inside of the cabinet via bearings. A drive motor is fixedly installed at the right end of the cabinet, and the output end of the drive motor is rotatably connected to the cabinet and fixedly connected to the rotating shaft. A cam is fixedly connected to the outer side of the rotating shaft, and a hinge rod is hinged to the inner side of the cam. A hinge seat is hinged to the outer side of the other end of the hinge rod, and the hinge seat is fixedly connected to the screen plate. A fixing rod is fixedly connected to the inner wall of the cabinet, and a fixing seat is fixedly connected to the outer side of the fixing rod. A spring is installed inside the fixing seat, with one end of the spring fixedly connected to an impact block and the other end fixedly connected to the fixing seat. By designing the spring, the spring force can act on the impact block. An impact block, which is an arc-shaped block made of high-elastic rubber, is slidably fitted inside the fixing seat to impact the screen plate. This screening mechanism allows for the screening of materials.

[0008] Preferably, there are two support plates, which are symmetrically distributed at the bottom of the cabinet. By designing the support plates, the cabinet can be supported.

[0009] Preferably, the dust collection mechanism includes a flexible hose, which is fixedly connected to the top of the housing. A magnetic cover is fixedly connected to the other end of the hose, and the magnetic cover adheres to the feed inlet. Two symmetrically distributed filter plates are slidably fitted inside the housing. An air pump is fixedly installed on the bottom of the inner wall of the housing. A suction port is located at the right end of the air pump, and an exhaust port is located at the bottom of the air pump, with the exhaust port fixedly connected to the housing.

[0010] Preferably, a support sleeve is slidably fitted onto the outer side of the filter plate, and the support sleeve is fixedly connected to the housing. The support sleeve provides support for the filter plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, through the design of multiple screen plates, can realize multi-stage screening of materials. During screening, the drive motor drives the rotating shaft to rotate, which in turn drives the cam to rotate. The rotation of the cam will drive the hinge rod to deflect, which can realize the reciprocating sway of the screen plate in the vertical direction. This can prevent the screen plate from being blocked and affecting the screening effect. Furthermore, when the screen plate moves, it can collide with the impact block. Under the elastic action of the screen plate and screen mesh, the screen mesh can vibrate, which can further improve the anti-blocking effect of the screen plate and improve the material screening efficiency.

[0013] 2. This utility model utilizes an air pump to create a negative pressure inside the chamber. The air pump can then draw air into the chamber through a flexible hose and magnetic cover, allowing fine particles and dust generated during the screening process to be drawn into the chamber along with the air. Combined with the filter plate, this effectively filters and purifies the fine particles and dust, preventing the spillage of dust during screening from polluting the external environment.

[0021] Please see Figure 1 , Figure 2 , Figure 3 The screening mechanism 8 includes a rotating shaft 81. The rotating shaft 81 is rotatably connected to the inside of the cabinet 1 via bearings. A drive motor 85 is fixedly installed at the right end of the cabinet 1. The output end of the drive motor 85 is rotatably connected to the cabinet 1 and fixedly connected to the rotating shaft 81. A cam 82 is fixedly connected to the outer side of the rotating shaft 81. A hinge rod 83 is hinged to the inner side of the cam 82. A hinge seat 84 is hinged to the outer side of the other end of the hinge rod 83. The hinge seat 84 is fixedly connected to the screen plate 6. A fixing rod 86 is fixedly connected to the inner wall of the cabinet 1. A fixed base 87 is fixedly connected to the outside of the rod 86. A spring 88 is installed inside the fixed base 87. One end of the spring 88 is fixedly connected to the impact block 89, and the other end of the spring 88 is fixedly connected to the fixed base 87. By designing the spring 88, the force of the spring 88 can be applied to the impact block 89. The impact block 89 is slidably sleeved inside the fixed base 87. The impact block 89 is an arc-shaped block and is made of high-elastic rubber. By designing the impact block 89, it can impact the screen of the screen plate 6. By designing the screening mechanism 8, it can screen the material.

[0022] Please see Figure 1 , Figure 2 , Figure 4 The dust collection mechanism 9 includes a flexible hose 91. The top of the housing 5 is fixedly connected to the flexible hose 91, and the other end of the flexible hose 91 is fixedly connected to a magnetic cover 92. The magnetic cover 92 is attracted to the feed inlet 4. Inside the housing 5, two symmetrically distributed filter plates 93 are slidably sleeved. A support sleeve 94 is slidably sleeved on the outside of the filter plates 93. The support sleeve 94 is fixedly connected to the housing 5. By designing the support sleeve 94, the filter plates 93 can be supported. An air pump 95 is fixedly installed at the bottom of the inner wall of the housing 5.

[0023] The specific implementation process of this utility model is as follows: In use, the material to be screened is first added into the cabinet 1 through the feed inlet 4, and then the magnetic cover 92 is adsorbed onto the feed inlet 4. Under the action of multiple screen plates 6, multi-stage screening of the material can be achieved. During screening, the drive motor 85 works simultaneously. The output end of the drive motor 85 drives the rotating shaft 81 to rotate. The rotating shaft 81 drives the cam 82 to rotate. The rotation of the cam 82 drives the hinge rod 83 to deflect, which in turn pushes the hinge seat 84 and the screen plate 6 to reciprocate vertically. This can prevent the screen plate 6 from being blocked and affecting the screening effect. When the screen plate 6 moves upward, it will contact the impact block 89. The impact block 89 will be squeezed and slide along the fixed seat 87 and squeeze the spring 88. Under the elastic action of the screen mesh of the screen plate 6, the screen mesh can vibrate, which can further improve the anti-blocking effect of the screen plate 6 and improve the material screening efficiency.

[0024] During the material screening process, the air pump 95 operates simultaneously. The air pump 95 draws air into the inside of the housing 5 through the suction port 96, creating a negative pressure inside the housing 5. Then, it draws air into the inside of the cabinet 1 through the hose 91 and the magnetic suction cover 92, so that the fine particles and dust generated during the screening process can be drawn into the inside of the housing 5 along with the air. With the help of the filter plate 93, the fine particles and dust can be filtered and purified, preventing the dust from overflowing during screening and causing pollution to the external environment.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
