Description

Technical Field

[0001] This utility model relates to the field of wastewater and air cleaning technology for coal preparation machines, specifically a high-efficiency dust removal device for dry separation equipment. Background Technology

[0002] With the continuous development of coal mining technology, the requirements for coal preparation equipment are increasing. The coal preparation process should have higher precision and efficiency, effectively remove impurities such as gangue and sulfur nodules, improve the utilization rate of coal resources, reduce environmental impact, and lower energy consumption and operating costs. At the same time, the safety and environmental protection performance of the equipment is also receiving more attention. As a commonly used coal preparation method, wind power coal preparation not only has the advantages of simple equipment structure, convenient operation, and high separation efficiency, but also has environmental advantages that wet coal preparation does not have, as it does not produce coal slime or wastewater. It has been widely used in the coal preparation industry. As an important component of wind power coal preparation, dust removal devices can avoid occupational health risks to workers caused by dust pollution.

[0003] Chinese Utility Model Patent Publication No. CN 220004941 U discloses a cleaning device and a coal preparation machine with the same. When the part to be cleaned is working normally, the cleaning component is offset from the cleaning hole to prevent it from affecting the operation of the part to be cleaned. When cleaning is required, the cleaning component moves to align with the cleaning hole and inserts itself into the hole to remove debris blocking it. However, although this cleaning device and coal preparation machine can prevent clogging during internal filtration, it is prone to leaking dust-laden gas into the underground air during use, causing dust to affect miners' breathing and resulting in air pollution. This leads to poor overall practicality of the coal preparation machine. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a high-efficiency dust removal device for dry separation equipment. It can effectively solve the problem that although the existing technology can prevent clogging during internal filtration, it is easy for dust-containing gas inside to leak into the underground air during use, which leads to dust affecting the health of employees and causing air pollution, resulting in poor overall practicality of the air coal separator.

[0005] The technical solution adopted by this utility model is: a high-efficiency dust removal device for dry separation equipment, including a conveyor and a dust removal component. The dust removal component is fixedly installed with a mounting box by bolts at one end away from the ground. The air classifier body is provided at the other end of the mounting box away from the dust removal component. A connecting pipe one adapted to the air classifier body is provided at one end of the dust removal component through a flange. A connecting pipe two is provided at the other side of the mounting box away from the connecting pipe one through a flange.

[0006] The dust removal assembly includes a dust removal box and a filter bag body adapted to the dust removal box. An installation frame with an "I" shaped cross-section is fixedly installed inside the dust removal box. The side of the installation frame away from the dust removal box has a through-hole that can limit the position of the filter bag body.

[0007] Preferably, a connecting cover is provided between the air separator body and the mounting box, and the connecting cover is an elastic cover.

[0008] Through the above technical solution, the design of the air separator body and the mounting box can reduce the shaking and resonance it experiences during operation due to the strong shaking during coal preparation, thereby improving its practicality.

[0009] Preferably, the outer surface of the dust collector is provided with a connecting flange, which is located below the filter bag body, and a sealing gasket and a side plate are fixedly installed at both ends of the dust collector.

[0010] Through the above technical solution and the design of the connecting flange, when using the overall dust removal component, it is only necessary to connect the connecting flange to the air separation equipment that needs dust removal, which can improve the versatility of the overall dust removal component and facilitate its installation on different air separation equipment, thereby increasing the versatility of the overall dust removal device.

[0011] Preferably, the sealing gasket is a rubber sealing gasket, and the sealing gasket is located between the dust collection box and the side plate.

[0012] The above technical solution ensures the sealing of both ends of the dust collector box by using a sealing gasket to prevent dust leakage. The side plates protect and support the internal components of the dust collector box. The good sealing performance ensures that the dust-laden gas will not leak into the underground air during the dust removal process, protecting the underground working environment, reducing the harm of dust to miners' health, and meeting the requirements of underground safe production. At the same time, the side plates also enhance the overall stability and durability of the dust collector box.

[0013] Preferably, the outer surface of the mounting bracket is provided with a positioning bolt, the inner surface of the mounting bracket is provided with a mounting groove, a sealing gasket is fixedly installed on the inner surface of the mounting groove, and a cloth bag body is provided on the inner surface of the mounting groove. The mounting groove, the sealing gasket, and the cloth bag body are in one-to-one correspondence.

[0014] With the above technical solution, when installing the filter bag body, the filter bag body is placed into the installation groove. Since there is a sealing gasket 2 in the installation groove, the sealing between the filter bag body and the installation groove can be ensured. Then, the mounting bracket is fixed in the dust collector box by the positioning bolt 1. The sealing gasket 2 ensures that the dust-laden gas must be filtered through the filter bag body, which improves the dust removal efficiency. The one-to-one corresponding installation groove and filter bag body design makes the installation and replacement of the filter bag more convenient and quick. When a filter bag needs maintenance or replacement, it can be accurately located and operated.

[0015] Preferably, the outer surface of the mounting frame is provided with a positioning block and a second positioning bolt. Two identical second positioning bolts are provided, one of which is fixedly installed with the mounting frame. The positioning block is adapted to the bag body.

[0016] With the above technical solution, after the bag body is installed, the positioning block is installed in the corresponding position of the bag body and fixed with another positioning bolt. Together with the already fixed positioning bolt, the position of the bag body is further stabilized, preventing it from shifting or shaking during operation, and also facilitating the quick replacement of the bag body.

[0017] Preferably, the other ends of the first connecting pipe and the second connecting pipe are connected to the dust removal component, the first connecting pipe and the second connecting pipe are in communication with the dust removal component, a feed hopper is fixedly installed at the end of the conveyor away from the dust removal component, and a discharge hopper is fixedly installed at the other end of the conveyor away from the feed hopper.

[0018] Through the above technical solution, during the operation of the air classifier, the dust-laden airflow generated in the air classifier body is transported to the dust removal component through connecting pipe one and connecting pipe two. This enables timely collection of dust generated during the air classification process and its introduction into the dust removal component for treatment, preventing dust from spreading around the air classifier and protecting the underground working environment. At the same time, the interconnected design of the connecting pipes ensures smooth transmission of the dust-laden airflow, avoiding blockage and leakage problems, improving the overall efficiency and reliability of the dust removal system, and ensuring that the air classifier can operate continuously and stably.

[0019] Compared with the prior art, this utility model provides a high-efficiency dust removal device for dry separation equipment, which has the following beneficial effects:

[0020] 1. The high-efficiency dust removal device of this dry separation equipment, with sealing gaskets and side plates at both ends of the dust collection box, ensures that dust-laden gas does not leak into the underground ventilation device, effectively protecting the cleanliness of the underground airflow, preventing harm to the health of employees, and meeting the environmental protection requirements for safe production underground. The high-efficiency bag dust collection system can effectively handle the coal dust generated by air separation, realize the closed internal circulation of airflow within the air separation system, and protect the efficient and safe operation of internal equipment. At the same time, the reasonable design of the connecting pipeline ensures smooth transmission of dust-laden airflow, improves the efficiency and reliability of the dust removal system, maintains good air quality underground, and promotes safe production.

[0021] 2. The high-efficiency dust removal device of this dry separation equipment, with sealing gasket one and side plates enhancing the stability and durability of the dust collection box, reduces equipment failures caused by dust erosion and structural instability, lowers maintenance costs, ensures long-term stable operation of the equipment, and improves the reliability and service life of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: As Figure 1-7 As shown, the present invention provides a high-efficiency dust removal device for dry separation equipment, including a conveyor 1 and a dust removal component 8. The dust removal component 8 is fixedly installed with a mounting box 6 by bolts at one end away from the ground. The air separator body 4 is provided at the other end of the mounting box 6 away from the dust removal component 8. A connecting pipe 7 adapted to the air separator body 4 is provided at one end of the dust removal component 8 through a flange. A connecting pipe 9 is provided at the other side of the mounting box 6 away from the connecting pipe 7 through a flange.

[0033] The dust removal assembly 8 includes a dust removal box 801 and a filter bag body 809 adapted to the dust removal box 801. A mounting frame 805 with an "I" shaped cross-section is fixedly installed inside the dust removal box 801. A mounting groove 807 that can limit the position of the filter bag body 809 is provided on the side of the mounting frame 805 away from the dust removal box 801.

[0034] Specifically, a connecting cover 5 is provided between the air separator body 4 and the mounting box 6. The connecting cover 5 is an elastic cover. The advantage is that, through the design of the air separator body 4 and the mounting box 6, the shaking and resonance experienced by both during operation can be reduced to a certain extent due to the strong shaking during coal preparation, thus improving its practicality.

[0035] Specifically, a connecting flange 802 is provided on the outer surface of the dust collector 801. The connecting flange 802 is located below the filter bag body 809. Sealing gaskets 803 and side plates 804 are fixedly installed at both ends of the dust collector 801. The advantage is that, through the design of the connecting flange 802, when using the overall dust collection assembly 8, it is only necessary to connect the connecting flange 802 to the air separation equipment that needs dust removal, which can improve the versatility of the overall dust collection assembly 8 and facilitate its installation on different air separation equipment, thereby improving the versatility of the overall dust collection device.

[0036] Specifically, sealing gasket 803 is a rubber sealing gasket located between dust collector 801 and side plate 804. Its advantages are that sealing gasket 803 ensures the sealing of both ends of dust collector 801, preventing dust leakage. Side plate 804 protects and supports the internal components of dust collector 801. Good sealing ensures that dust-laden gas will not leak into the underground air during dust removal, protecting the underground working environment, reducing the health hazards of dust to miners, and meeting the requirements for safe underground production. At the same time, the installation of sealing gasket 803 and side plate 804 also enhances the overall stability and durability of dust collector 801.

[0037] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, a mounting bracket 805 is fixedly installed on the inner surface of the dust collector 801. A positioning bolt 806 is provided on the outer surface of the mounting bracket 805. An installation groove 807 is formed on the inner surface of the mounting bracket 805. A sealing gasket 808 is fixedly installed on the inner surface of the installation groove 807. A filter bag body 809 is provided on the inner surface of the installation groove 807. The installation groove 807, the sealing gasket 808, and the filter bag body 809 correspond one-to-one. The advantage is that when installing the filter bag body 809, it is placed into the installation groove 807. The mounting slot 807 contains a second sealing gasket 808, which ensures the seal between the bag body 809 and the mounting slot 807. Then, the mounting bracket 805 is fixed in the dust collector box 801 by the positioning bolt 806. The second sealing gasket 808 ensures that the dust-laden gas must pass through the bag body 809 for filtration, thus improving the dust removal efficiency. The one-to-one correspondence between the mounting slot 807 and the bag body 809 makes the installation and replacement of the bag more convenient and quick. When a bag needs maintenance or replacement, it can be accurately located and operated.

[0039] Specifically, the outer surface of the mounting bracket 805 is provided with a positioning block 810 and a second positioning bolt 811. Two identical positioning bolts 811 are provided. One positioning bolt 811 is fixedly installed with the mounting bracket 805, and the positioning block 810 is adapted to the bag body 809. The advantage is that after the bag body 809 is installed, the positioning block 810 is installed in the corresponding position of the bag body 809 and fixed with the other positioning bolt 811. Together with the already fixed positioning bolt 811, the position of the bag body 809 is further stabilized, preventing it from shifting or shaking during operation, and also facilitating the quick replacement of the bag body 809.

[0040] Specifically, the other ends of connecting pipe 7 and connecting pipe 9 are connected to the dust removal component 8. Connecting pipe 7 and connecting pipe 9 are connected to the dust removal component 8. A feed hopper 2 is fixedly installed at the end of conveyor 1 away from the dust removal component 8, and a discharge hopper 3 is fixedly installed at the other end of conveyor 1 away from the feed hopper 2. The advantage is that during the operation of the air classifier, the dust-laden airflow generated in the air classifier body 4 is transported to the dust removal component 8 through connecting pipe 7 and connecting pipe 9. This can collect the dust generated during the air classification process and introduce it into the dust removal component 8 for treatment in a timely manner, preventing the dust from spreading around the air classifier and protecting the underground working environment. At the same time, the interconnected design of the connecting pipes ensures the smooth transmission of the dust-laden airflow, avoids blockage and leakage problems, improves the overall efficiency and reliability of the dust removal system, and ensures that the air classifier can operate continuously and stably.

[0041] Working principle: During use, the material enters through the feed hopper 2 of the conveyor 1 and falls into the air separator body 4 through the discharge hopper 3 for air separation. The dust-laden airflow generated during the air separation process is transported to the dust removal component 8 through connecting pipe 1 7 and connecting pipe 2 9. After the dust-laden airflow enters the dust removal box 801, it needs to be filtered through the filter bag body 809 in the mounting groove 807 on the mounting frame 805. The sealing gasket 2 808 between the filter bag body 809 and the mounting groove 807 ensures that the dust-laden gas can only pass through the filter bag, thereby improving the dust removal efficiency. The filtered clean gas is discharged, and the dust is left on the filter bag, thus achieving filtration.

[0042] 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.
