Description

Technical Field

[0001] This utility model relates to the field of heavy metal pollution prevention and control, and in particular to an integrated equipment for pretreatment and feeding of arsenic-containing gypsum slag. Background Technology

[0002] Arsenic-containing gypsum slag, also known as arsenic-calcium slag, mainly originates from the desulfurization of smelting flue gas and the treatment of arsenic-containing waste acid using lime and iron salt methods. Its main component is calcium sulfate (CaSO4·2H2O), and it also contains heavy metal elements such as arsenic (As) and lead (Pb). It is classified as hazardous solid waste. Although there is currently no direct description of equipment for the pretreatment and feeding of arsenic-containing gypsum slag, a concept of an integrated pretreatment and feeding device can be conceived based on the treatment requirements of arsenic-containing gypsum slag.

[0003] The integrated pretreatment and feeding equipment for arsenic-containing gypsum slag can be widely used in smelting, chemical, and environmental protection fields. It is of great significance for the treatment of hazardous solid wastes such as arsenic-containing gypsum slag. Through the treatment of arsenic-containing gypsum slag, the resource utilization and harmless treatment of arsenic-containing gypsum slag can be realized, reducing environmental pollution and resource waste. The pretreated gypsum slag is stored and accurately metered according to the treatment requirements to ensure the accuracy and stability of feeding.

[0004] The existing technology has the following defects: after the gypsum slag is pretreated, it enters the storage and metering system and is accurately metered according to the processing requirements. The metered gypsum slag is then transported to the subsequent processing equipment or storage location by conveyor belt. However, during the transportation process, the slag is directly exposed to the outside and inevitably floats and generates dust, which affects the surrounding environment and the health of the workers. Therefore, an integrated pretreatment and feeding device for arsenic-containing gypsum slag is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an integrated pretreatment and feeding device for arsenic-containing gypsum slag, which aims to improve the problem in the prior art where metered gypsum slag is transported to subsequent processing equipment or storage locations via conveyor belt, but dust inevitably floats and rises during the transportation process because the slag is directly exposed to the outside.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an integrated pretreatment and feeding device for arsenic-containing gypsum slag, comprising a main body of the integrated feeding device, a gypsum slag inlet, a pretreatment machine body, a control panel, and an active roller. The active roller is equipped with a dispensing mechanism. The pretreatment machine body contains an auxiliary mechanism. The dispensing mechanism includes a conveyor belt, which is in contact with the outer side wall of the active roller. A limiting groove is formed on the top outer wall of the conveyor belt. A transport box is engaged with the bottom inner wall of the limiting groove. A groove is formed on the right inner wall of the transport box. Sealing plates are slidably connected to the left and right inner walls of the groove. A lever is slidably connected to the right inner wall of the sealing plate. An arc-shaped plate is fixedly connected to the rear outer wall of the lever, and a compression spring is fixedly connected to the front outer wall of the lever.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a mounting frame, which is slidably connected to the inner front wall of the pretreatment chassis body. The inner bottom wall of the mounting frame is fixedly connected to the main body of the control component. An adjustment plate is slidably connected to the inner front wall of the mounting frame. A locking plate is fixedly connected to the outer right side wall of the adjustment plate. A small spring is fixedly connected to the outer left side wall of the adjustment plate. A telescopic spring is fixedly connected to the outer rear wall of the mounting frame.

[0008] As a further description of the above technical solution: a motor is fixedly connected to the rear outer wall of the main body of the integrated feeding device, and the drive roller is fixedly connected to the output end of the motor through a coupling.

[0009] As a further description of the above technical solution: the arc-shaped plate penetrates the outer right wall of the sealing plate, and the arc-shaped plate is snapped into the inner right wall of the transport box.

[0010] As a further description of the above technical solution: frosted pads are fixedly connected to the outer walls of the front and rear sides of the paddle, and the end of the compression spring away from the paddle is fixedly connected to the inner wall of one side of the sealing plate.

[0011] As a further description of the above technical solution: the main body of the control component is electrically connected to the control panel, the card plate is snapped onto the inner right side of the pretreatment chassis main body, and the outer wall of the small spring away from the adjustment plate is fixedly connected to the inner wall of the mounting bracket.

[0012] As a further description of the above technical solution: the end of the telescopic spring away from the mounting bracket is fixedly connected to the rear inner wall of the pretreatment chassis body, and a viewing window is fixedly connected to the front inner wall of the mounting bracket.

[0013] As a further description of the above technical solution: the gypsum slag inlet is fixedly connected to the top outer wall of the main body of the integrated feeding equipment, the pretreatment machine body is fixedly connected to the bottom inner wall of the gypsum slag inlet, the control panel is fixedly connected to the front outer wall of the main body of the integrated feeding equipment, and the drive roller is rotatably connected to the right inner wall of the main body of the integrated feeding equipment via a bearing.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting up structures such as sealing plates, arc plates, and transport boxes, the gypsum slag is sealed during transportation to prevent it from splashing outwards and causing pollution to the surrounding environment. The transport boxes on the conveyor belt are also limited to prevent them from shifting and falling off during movement.

[0016] 2. In this utility model, by setting adjustment plates, card plates, mounting brackets and other structures, it is convenient for personnel to easily pull out the internal control components, which improves the narrow space inside the traditional pretreatment machine chassis, making it inconvenient for personnel to go deep into the inspection, thereby improving work and maintenance efficiency.

[0025] Reference Figures 2-4 A motor is fixedly connected to the rear outer wall of the main body 1 of the integrated feeding equipment. The drive roller 5 is fixedly connected to the output end of the motor through a coupling. An arc plate 67 penetrates the right outer wall of the sealing plate 65. The arc plate 67 is set to make the sealing plate 65 and the transport box 63 interlock and seal each other. The arc plate 67 is interlocked with the right inner wall of the transport box 63. Abrasive pads are fixedly connected to the front and rear outer walls of the paddle 66. The abrasive pads increase the surface friction of the paddle 66. The end of the compression spring 68 away from the paddle 66 is fixedly connected to the inner wall of the sealing plate 65. The gypsum slag inlet 2 is fixedly connected to the top outer wall of the main body 1 of the integrated feeding equipment. The pretreatment machine body 3 is fixedly connected to the bottom inner wall of the gypsum slag inlet 2. The control panel 4 is fixedly connected to the front outer wall of the main body 1 of the integrated feeding equipment. The drive roller 5 is rotatably connected to the right inner wall of the main body 1 of the integrated feeding equipment through a bearing.

[0026] Reference Figures 3-4The auxiliary mechanism 7 includes a mounting frame 71, which is slidably connected to the inner front wall of the pretreatment chassis 3. A control component body 72 is fixedly connected to the inner bottom wall of the mounting frame 71. An adjusting plate 73 is slidably connected to the inner front wall of the mounting frame 71. A locking plate 74 is fixedly connected to the outer right side of the adjusting plate 73. A small spring 75 is fixedly connected to the outer left side of the adjusting plate 73, generating a continuous thrust on the adjusting plate 73 through the small spring 75. A telescopic spring 76 is fixedly connected to the outer rear wall of the mounting frame 71, allowing for continuous thrust through the telescopic spring. Spring 76 exerts an outward thrust on mounting bracket 71. Control component body 72 is electrically connected to control panel 4.

Small spring 75 is fixedly connected to the outer wall of the side away from adjustment plate 73 to the inner wall of the side of mounting bracket 71. Extension spring 76 is fixedly connected to the rear inner wall of pretreatment chassis body 3 at the end away from mounting bracket 71. A viewing window 77 is fixedly connected to the front inner wall of mounting bracket 71. The viewing window 77 facilitates personnel to observe the interior of pretreatment chassis body 3.

[0027] Working principle: The treated gypsum residue is loaded into the transport box 63, and then the sealing plate 65 is inserted into the groove 64, so that the arc plate 67 is engaged with the inner wall of one side of the transport box 63, sealing the top opening of the transport box 63. Then the transport box 63 is placed into the limiting groove 62. The motor is turned on to make the drive roller 5 rotate. The rotation of the drive roller 5 drives the conveyor belt 61 to move. The movement of the conveyor belt 61 drives the transport box 63 to move. At the same time, the limiting groove 62 prevents the transport box 63 from shifting during the movement of the conveyor belt 61, which would cause the transport box 63 to fall off the conveyor belt 61. Since the pretreatment and feeding functions are integrated, the structure of the equipment may be relatively complex. The complex equipment structure may also lead to an increased failure rate and require regular inspection and maintenance. By pulling the adjusting plate 73, the clamping plate 74 is moved and the clamping plate 74 is disengaged from the inner wall of one side of the pretreatment machine body 3. Then, under the continuous thrust of the telescopic spring 76, the mounting frame 71 moves outward, which facilitates personnel to maintain the control component body 72 or other internal components.
