Description

Technical Field

[0001] The utility model relates to the field of screening equipment, and more specifically, to a multi-layer screening structure for zinc oxide production. Background Art

[0002] Zinc oxide is an inorganic compound that is widely used in various industrial and commercial fields. It is known for its excellent chemical stability and versatility. The following is a detailed introduction to zinc oxide, including its properties, production methods. Due to its unique properties and wide range of applications, zinc oxide plays an important role in many fields. When producing zinc oxide, a multi-layer screening structure is required, and screening is a crucial step to ensure the quality and particle size distribution of the final product. The multi-layer screening structure of zinc oxide can improve production efficiency and product consistency.

[0003] However, most of the existing multi-layer screening structures for zinc oxide production have the following problems:

[0004] First, in the existing multi-layer screening structure for zinc oxide production, during filtration, most use multiple filter meshes for filtration and screening. The filter meshes used are mostly in a fixed state. After a long time of filtration, it is easy for larger zinc oxide particles to clog the filter meshes, affecting the filtration effect. Moreover, if the filtered zinc oxide is not removed for use, it is easy for the accumulated zinc oxide to form lumps and stick together, making it inconvenient for full filtration treatment.

[0005] Second, in the existing multi-layer screening structure for zinc oxide production, most of the filter meshes used are fixed in the equipment for use. After a long time of using the filter meshes, it is easy for the filter meshes to deform and be damaged. If not replaced, it is easy to affect the subsequent filtration use effect, and it is inconvenient to disassemble and install the used filter meshes.

[0006] Therefore, we make improvements and propose a multi-layer screening structure for zinc oxide production. Summary of the Utility Model

[0007] The purpose of the present utility model is to address the problems of inconvenient full filtration treatment and inconvenient disassembly and installation of the used filter meshes currently existing.

[0008] To achieve the above purpose, the present utility model provides the following technical solutions:

[0010] Specifically, this application is as follows:

[0011] It includes a device housing, on which a feed pipe is fixedly connected. Inside the device housing, a material rack is arranged, and a filter screen plate is arranged inside the material rack. On the device housing, a motor is fixedly connected. The output shaft of the motor is fixedly connected to a connecting shaft, and the connecting shaft is rotatably connected inside the device housing. A support plate is fixedly connected to the connecting shaft, and a first connecting rod is fixedly connected to the support plate. A second connecting rod is fixedly connected to the material rack. A first pushing block is fixedly connected to the first connecting rod, and a second pushing block is fixedly connected to the material rack. A guiding block is fixedly connected to the material rack, and a first spring is fixedly connected to the guiding block. The other end of the first spring is fixedly connected inside the device housing. A sleeve is rotatably connected to the connecting shaft, and the sleeve is fixedly connected inside the device housing. A screw blade is fixedly connected to the connecting shaft. A first sealing plate is bolted to the device housing. A connecting block is arranged inside the material rack and the filter screen plate. A second spring is fixedly connected inside the connecting block, and the other end of the second spring is fixedly connected to a limiting plate. A first clamping block is fixedly connected to the limiting plate, and a pulling plate is fixedly connected to the limiting plate.

[0012] As a preferred technical solution of the present application, the output shaft of the motor is fixedly connected to the central part of one end of the connecting shaft, and the cross-sections of the first pushing block and the second pushing block are isosceles triangles.

[0013] As a preferred technical solution of the present application, the guiding blocks are symmetrically distributed on the left and right sides of the material rack, and the guiding blocks correspond to the first springs one by one.

[0014] As a preferred technical solution of the present application, the side end face of the screw blade is in contact with the inner side face of the sleeve, and the side end face of the limiting plate is in contact with the inner side face of the connecting block.

[0015] As a preferred technical solution of the present application, the second springs are symmetrically distributed on the left and right sides inside the connecting block, and the second springs correspond to the first clamping blocks through the limiting plates one by one.

[0016] As a preferred technical solution of the present application, a second clamping block is fixedly connected to the connecting block, and a second sealing plate is bolted to the device housing. The second clamping blocks are equidistantly distributed on the connecting block.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] In the solution of the present application:

[0019] 1. There is a material rack. When high-power production of zinc oxide is carried out, materials can be added into the device housing through the feed pipe and fall into the filter screen plate in the material rack. Start the motor to drive the connecting shaft to rotate. When the connecting shaft rotates, it can drive the first connecting rod to rotate through the support plate. When the first connecting rod rotates, it can push the second push block on the material rack through the first push block. The inclined surfaces of the first push block and the second push block cooperate to push the material rack downward. When the material rack moves downward, it can press the material rack to move through the second connecting rod. When the material rack moves, it can squeeze the first spring through the guide block. After the first connecting rod drives the first push block to move past, the material rack is unobstructed. Under the push of the first spring, it drives the material rack on the guide block to reset and shake. And the second connecting rod of the upper material rack can release the lower material rack, and the material rack can shake, shake the materials in the material rack, and use the filter screen plate for filtration. When shaking, it can prevent the materials from blocking the filter screen plate. The filtered materials fall to the bottom inside the device housing, and the auger blades can be driven to rotate through the connecting shaft. The auger blades can transport the materials at the bottom to the upper part and discharge them from the upper part and fall into the material rack, playing a role of circular filtration, avoiding situations such as caking of the materials accumulated at the bottom, and improving the filtration effect.

[0020] 2. There is a connecting block. When disassembling the damaged filter screen plate from the material rack, the pull plates on both sides of the connecting block can be squeezed. The pull plates drive the limiting plate to move. When the limiting plate moves, it can squeeze the second spring. At the same time, the limiting plate can drive the first clamping block to fall off from the material rack and the filter screen plate and retract into the connecting block. When the connecting block is unobstructed, the connecting block and the second clamping block can be taken out. After the filter screen plate is unobstructed after being taken out, it can be taken out for replacement. When fixing the replaced filter screen plate, the second clamping block on the connecting block can be inserted into the material rack and the filter screen plate, and the pull plates on both sides are loosened. Under the push of the second spring, it drives the limiting plate and the first clamping block to reset. The first clamping block can be clamped in the material rack and the filter screen plate, playing a role of fixing and limiting, and improving the disassembly and installation effect.

[0037] Embodiment 2:

[0038] The solution in Embodiment 1 will be further introduced below in combination with the specific working mode. See the following description for details:

[0039] As Figure 6 shown, as a preferred embodiment, on the basis of the above method, further, the output shaft of the motor 5 is fixedly connected to the central part of one end of the connecting shaft 6. The cross-sections of the first push block 10 and the second push block 11 are isosceles triangles, which can ensure the cooperation of the inclined surfaces of the first push block 10 and the second push block 11 and can play a role in pushing and moving downward.

[0040] As Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, the guiding blocks 12 are symmetrically distributed on the left and right sides of the rack 3, and the guiding blocks 12 correspond to the first springs 13 one by one, which can ensure the cooperation between the guiding blocks 12 on both sides and the first springs 13, and can play a stable pushing and jittering role.

[0041] As Figure 7 shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the auger blade 15 is in contact with the inner side face of the sleeve 14, and the side end face of the limiting plate 19 is in contact with the inner side face of the connecting block 17, which can ensure that when the limiting plate 19 moves, it can move smoothly through the support of the inner side face of the connecting block 17.

[0042] As Figure 7 shown, as a preferred embodiment, on the basis of the above method, further, the second springs 18 are symmetrically distributed on the left and right sides inside the connecting block 17, and the second springs 18 correspond to the first clamping blocks 20 through the limiting plate 19 one by one, which can ensure the clamping of the first clamping blocks 20 on both sides and can stably clamp and limit the rack 3 and the filter screen plate 4.

[0043] As Figure 7 shown, as a preferred embodiment, on the basis of the above method, further, a second clamping block 22 is fixedly connected to the connecting block 17, and a second sealing plate 23 is bolted to the device housing 1. The second clamping blocks 22 are equidistantly distributed on the connecting block 17, which can ensure the stable clamping and installation of the equidistantly distributed second clamping blocks 22.

[0044] Specifically, when the multi-layer screening structure for zinc oxide production is in use: Combining Figure 1-8, when the produced zinc oxide is under high power, materials can be added into the device housing 1 through the feed pipe 2 and fall into the filter mesh plate 4 in the material rack 3. Start the motor 5 to drive the connecting shaft 6 to rotate. When the connecting shaft 6 rotates, it can drive the first connecting rod 8 to rotate through the support plate 7. When the first connecting rod 8 rotates, it can push the second push block 11 on the material rack 3 through the first push block 10. The inclined surfaces of the first push block 10 and the second push block 11 cooperate to push the material rack 3 downward. When the material rack 3 moves downward, it can press the material rack 3 to move through the second connecting rod 9. When the material rack 3 moves, it can squeeze the first spring 13 through the guide block 12. After the first connecting rod 8 drives the first push block 10 to move past, the material rack 3 is unobstructed, and under the push of the first spring 13, it drives the material rack 3 on the guide block 12 to reset and vibrate. Moreover, the second connecting rod 9 of the upper material rack 3 can release the lower material rack 3, and the material rack 3 can vibrate, vibrating the materials in the material rack 3 and using the filter mesh plate 4 for filtration treatment. Vibration can prevent materials from blocking the filter mesh plate 4. The filtered materials fall to the bottom inside the device housing 1. The auger blade 15 can be driven to rotate through the connecting shaft 6. The auger blade 15 can transport the materials at the bottom from the sleeve 14 to the upper part and discharge them, falling into the material rack 3, playing a role of circulating filtration, preventing the materials accumulated at the bottom from caking and other situations, and improving the filtration effect.

[0045] When disassembling the damaged filter mesh plate 4 from the material rack 3, the two side pull plates 21 of the connecting block 17 can be squeezed. The pull plates 21 drive the limit plate 19 to move. When the limit plate 19 moves, it can squeeze the second spring 18. At the same time, the limit plate 19 can drive the first clamping block 20 to fall off from the material rack 3 and the filter mesh plate 4 and retract into the connecting block 17. When the connecting block 17 is unobstructed, the connecting block 17 and the second clamping block 22 can be taken out. After the filter mesh plate 4 is unobstructed, it can be taken out for replacement. When fixing the replaced filter mesh plate 4, the second clamping block 22 on the connecting block 17 can be inserted into the material rack 3 and the filter mesh plate 4, and the two side pull plates 21 are released. Under the push of the second spring 18, the limit plate 19 and the first clamping block 20 are reset. The first clamping block 20 can be clamped in the material rack 3 and the filter mesh plate 4, playing a role of fixing and limiting, improving the disassembly and installation effect. When it is necessary to take out the filtered zinc oxide, the first sealing plate 16 on the device housing 1 can be disassembled to take out and collect the zinc oxide inside. At the same time, when cleaning the larger materials on the filter mesh plate 4 in the material rack 3, the second sealing plate 23 on the device housing 1 can be disassembled to clean the inside.
