Description

Technical Field

[0001] This invention belongs to the field of dust control technology, and specifically discloses a dust control device for coal mining construction. Background Technology

[0002] During coal mining operations, large amounts of dust are generated during tunneling, blasting, transportation, and loading / unloading. This dust not only severely pollutes the underground and surrounding working environment, affecting visibility and equipment operation, but also poses a threat to the respiratory health of workers, with long-term exposure potentially leading to occupational diseases such as pneumoconiosis. Furthermore, high concentrations of dust can trigger explosions, posing a serious threat to coal mine safety. Therefore, how to efficiently and sustainably control dust generated during coal mining has always been a critical issue that urgently needs to be addressed in the field of mine environmental protection and safety production.

[0003] Currently, common dust control methods in coal mines mainly include water spraying, ventilation and dust removal, wet scrubbers, and bag filters. Water spraying is simple and easy to implement, but its dust suppression effect is limited, especially its ability to capture fine dust, and it easily leads to water accumulation in the work area, affecting equipment and personnel movement. While ventilation and dust removal can dilute dust concentration, it does not achieve effective dust collection and treatment, potentially causing dust to spread to other areas. Wet scrubbers and bag filters have good dust removal effects under certain conditions, but they suffer from problems such as large equipment size, frequent maintenance, easy clogging of filter media, and unsuitability for environments with continuous high dust concentrations. Especially in continuously operating coal mining faces, existing dust removal equipment often struggles to simultaneously meet the requirements of high-efficiency filtration, continuous operation, and ease of cleaning.

[0004] Furthermore, traditional dust removal devices are often complex in structure and energy consumption in terms of filter material regeneration, dust collection and removal, and the cleaning process can easily cause secondary dust generation, reducing the overall dust removal efficiency. Therefore, there is an urgent need for a dust control device that can adapt to the characteristics of coal mining operations, achieve efficient filtration, continuous operation, automatic cleaning and easy maintenance, in order to improve underground air quality and protect the health of workers and mine safety. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a dust control device for coal mining operations to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention provides a dust control device for coal mining operations, comprising a filter belt, an air-permeable belt adhered to the filter belt, a connecting belt adhered to the air-permeable belt, and embedded blocks fixed at equal intervals on the connecting belt. Each embedded block has a rectangular hole, and a sealing strip is embedded inside the rectangular hole. The two ends of the sealing strip are fixed to the inner wall of the rectangular hole. The filter belt, the breathable belt, and the connecting belt are all annular belt structures. A dust suction hood is abutted on the connecting belt, and a transmission structure is connected to the connecting belt. The dust collection hood has water spray nozzles above it that spray water onto the filter belt, and a scraper that scrapes the filter belt below it.

[0007] In the above technical solution, the transmission structure further includes a first abutting belt fixed to one side of the connecting belt, a transmission belt fixed to the other side of the connecting belt, the first abutting belt and the transmission belt being fixed to the breathable belt and the filter belt, the inner walls of the first abutting belt and the transmission belt abutting against a first support plate, and the first abutting belt and the transmission belt sliding on the first support plate.

[0008] In the above technical solution, a second baffle is abutted against the first support plate near the first abutting belt, and a first baffle is abutted against the first support plate near the transmission belt. An inner shell is detachably connected between the first baffle and the second baffle, and the inner shell is wrapped around the outside of the filter belt.

[0009] In the above technical solution, the spray head and the inner shell are fixedly connected, a collection box is fixed to the lower part of the inner shell, a first collection port and a second collection port are connected to the collection box, the first collection port is fixed to the scraper, and the second collection port is fixed to the lower part of the inner shell.

[0010] In the above technical solution, a dust collection box is further fixed on the side of the inner shell away from the dust collection hood, and a cleaning roller rotates inside the dust collection box, with the cleaning roller abutting against the outside of the filter belt.

[0011] In the above technical solution, a transmission column is rotatably connected between the first support plate abutting the first abutting belt and the first support plate abutting the transmission belt. Connecting shells are fixed at equal intervals on the transmission column. Impact blocks slide on the connecting shells. The impact blocks abut against the connecting belt. The side of the impact block abutting against the connecting belt is an arc surface. A transmission motor is connected to both the transmission column and the cleaning roller. The transmission motor is fixed on the second baffle.

[0012] In the above technical solution, a transmission ring is further fixed at one end of the transmission column near the transmission belt, the transmission ring abuts against the transmission belt, and the transmission ring rotates on the first support plate and the first baffle.

[0013] In the above technical solution, a support roller is rotatably mounted on the first support plate, and the support roller abuts against the connecting belt. There are multiple support rollers.

[0014] In the above technical solution, the side of the filter belt away from the breathable belt is rough, the filter belt absorbs water, the filter belt and the breathable belt are breathable, the connecting belt, the embedded block and the sealing strip are not breathable, the sealing strip is elastic, and the two sides of the sealing strip are not fixed to the inner wall of the rectangular hole of the embedded block.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The exhaust end of the dust collection hood in this device is connected to an external air pump. The external air pump can exhaust the air inside the dust collection hood. At this time, the inside of the dust collection hood is in a negative pressure state. The side of the filter belt away from the ventilator belt is rough. This allows the external air to squeeze the sealing strip and be sucked into the inside of the dust collection hood when it passes through the filter belt, ventilator belt and rectangular holes on the embedded block. When the external air passes through the filter belt, the dust particles in the external air are adsorbed on the filter belt, thereby realizing the dust control of coal mining construction by this device.

[0016] 2. The output shaft of the drive motor in this device can drive the drive ring to rotate through the drive column. Since the drive ring and the drive belt are in contact, and the drive belt, filter belt, ventilation belt, and connecting belt are fixed, when the drive ring drives the drive belt to move, the drive belt also drives the filter belt, ventilation belt, and connecting belt to move. This allows the filter belt to filter dust particles in the external air at different positions, enabling the device to continuously control dust generated during coal mining operations.

[0017] 3. When external air compresses the sealing strip in this device, the sealing strip will deform. Because the sealing strip is elastic, when external air does not pass through the rectangular hole on the embedded block, the sealing strip can return to its initial state under its own restoring force. This ensures that the part of the filter belt away from the dust collection hood is not penetrated by external air, which facilitates the scraper to remove dust particles from the filter belt. When the scraper removes dust particles from the filter belt, the collection box can collect the dust particles removed by the scraper, thereby realizing the centralized collection of dust particles generated during coal mining operations.

[0018] 4. The filter belt in this device can be made of cotton cloth with a velvety surface. Before the filter belt filters dust particles, the receiving end of the spray head is connected to an external water pump. The external water pump can spray water onto the surface of the filter belt through the spray head. When the spray head sprays water onto the surface of the filter belt, the velvety surface of the filter belt will be wetted by the water, and a water film will be formed on the surface of the filter belt. This can increase the resistance of airflow through the filter belt, and at the same time improve the filtering intensity of the filter belt for dust particles, preventing the dust particles filtered by the filter belt from floating in the air again.

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0023] Example 1: Please refer to Figures 1-8 As shown, the present invention provides a technical solution: The present invention is a dust control device for coal mining construction, including a filter belt 5, a breathable belt 54 attached to the filter belt 5, a connecting belt 57 attached to the breathable belt 54, and embedded blocks 55 fixed at equal intervals on the connecting belt 57. The embedded blocks 55 have rectangular holes, and a sealing strip 56 is embedded inside the rectangular holes. The two ends of the sealing strip 56 are fixed to the inner wall of the rectangular holes. The filter belt 5, the ventilation belt 54 and the connecting belt 57 are all annular belt structures. The dust suction hood 72 is abutted on the connecting belt 57 and the transmission structure is connected to the connecting belt 57. Above the dust hood 72 are spray nozzles 1 that spray water onto the filter belt 5, and below the dust hood 72 are scrapers 61 that scrape the filter belt 5. The side of the filter belt 5 facing away from the breathable belt 54 is rough. The filter belt 5 absorbs water. The filter belt 5 and the breathable belt 54 are breathable. The connecting belt 57, the embedded block 55, and the sealing strip 56 are not breathable. The sealing strip 56 is elastic. The two sides of the sealing strip 56 are not fixed to the inner wall of the rectangular hole of the embedded block 55. In actual use, the exhaust end of the dust hood 72 is connected to an external air pump. The external air pump can exhaust the air inside the dust hood 72. At this time, the inside of the dust hood 72 is in a negative pressure state, which can enable the external air pressure to drive the connecting belt 57 to abut against the dust hood 72, thereby enabling the connecting belt 57 and the suction end of the dust hood 72 to abut against each other. Because the side of the filter belt 5 facing away from the ventilated belt 54 is rough, the connecting belt 57, the embedded block 55, and the sealing strip 56 are airtight. The sealing strip 56 is elastic, and the two sides of the sealing strip 56 are not fixed to the inner wall of the rectangular hole of the embedded block 55. This allows external air to pass through the rectangular hole on the filter belt 5, the ventilated belt 54, and the embedded block 55. The external air compresses the sealing strip 56 and is sucked into the dust collection hood 72. When external air passes through the filter belt 5, the dust particles in the external air are adsorbed on the filter belt 5, thereby achieving the dust control of coal mining operations by the device.

[0024] When the filter belt 5 is used for a long time, a lot of dust particles will be adsorbed on the surface of the filter belt 5. When a lot of dust particles are adsorbed on the surface of the filter belt 5, the filter belt 5 cannot play a good adsorption effect on dust particles in the outside air. Therefore, it is necessary to clean the dust particles on the filter belt 5. In order to make the device have a better dust particle cleaning effect, the following structure is proposed. Example 2: Please refer to Figures 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, the output shaft of the transmission motor 41 can drive the transmission ring 73 to rotate through the transmission column 75. Since the transmission ring 73 and the transmission belt 52 abut against each other, and the transmission belt 52 is fixed to the filter belt 5, the ventilation belt 54, and the connecting belt 57, it is possible to achieve that when the transmission ring 73 drives the transmission belt 52 to move, the transmission belt 52 also drives the filter belt 5, the ventilation belt 54, and the connecting belt 57 to move, thereby enabling the filter belt 5 to filter dust particles in the external air at different positions, and realizing the continuous dust control generated by coal mining operations.

[0025] The transmission structure includes a first abutting belt 51 fixed to one side of the connecting belt 57, and a transmission belt 52 fixed to the other side of the connecting belt 57. The first abutting belt 51 and the transmission belt 52 are fixed to the ventilation belt 54 and the filter belt 5. The inner walls of the first abutting belt 51 and the transmission belt 52 abut against a first support plate 53, and the first abutting belt 51 and the transmission belt 52 slide on the first support plate 53.

[0026] The first support plate 53 near the first abutting belt 51 abuts against the second baffle 4, and the first support plate 53 near the transmission belt 52 abuts against the first baffle 3. An inner shell 7 is detachably connected between the first baffle 3 and the second baffle 4, and the inner shell 7 is wrapped around the outside of the filter belt 5.

[0027] The spray head 1 is fixedly connected to the inner shell 7. A collection box 6 is fixed to the lower part of the inner shell 7. A first collection port 62 and a second collection port 63 are connected to the collection box 6. The first collection port 62 is fixed to the scraper 61, and the second collection port 63 is fixed to the lower part of the inner shell 7.

[0028] A dust collection box 2 is fixed on the side of the inner shell 7 away from the dust collection hood 72. A cleaning roller 21 rotates inside the dust collection box 2. The cleaning roller 21 abuts against the outside of the filter belt 5. The cleaning roller 21 is a columnar structure with bristles on its surface. In actual use, the bristles on the cleaning roller 21 can comb the lint on the filter belt 5.

[0029] A transmission column 75 rotates between the first support plate 53 abutting the first abutting belt 51 and the first support plate 53 abutting the transmission belt 52. Connecting shells 76 are fixed at equal intervals on the transmission column 75. Impact blocks 74 slide on the connecting shells 76. Impact blocks 74 abut against the connecting belt 57. The side of the impact block 74 that abuts against the connecting belt 57 is an arc surface. A transmission motor 41 is connected to both the transmission column 75 and the cleaning roller 21. The transmission motor 41 is fixed on the second baffle 4.

[0030] A transmission ring 73 is fixed at one end of the transmission column 75 near the transmission belt 52. The transmission ring 73 abuts against the transmission belt 52 and rotates on the first support plate 53 and the first baffle 3.

[0031] A support roller 71 rotates on the first support plate 53. The support roller 71 abuts against the connecting belt 57. There are multiple support rollers 71. In actual use, the output shaft of the drive motor 41 can drive the drive ring 73 to rotate through the drive column 75. Since the drive ring 73 and the drive belt 52 abut against each other, and the drive belt 52 is fixed to the filter belt 5, the ventilation belt 54, and the connecting belt 57, it can be realized that when the drive ring 73 drives the drive belt 52 to move, the drive belt 52 also drives the filter belt 5, the ventilation belt 54, and the connecting belt 57 to move, thereby enabling the filter belt 5 to filter dust particles in the external air at different positions, so as to realize the continuous dust control of coal mining construction by the device. When external air compresses the sealing strip 56, the sealing strip 56 will deform. Because the sealing strip 56 is elastic, when the external air does not pass through the rectangular hole on the embedded block 55, the sealing strip 56 can return to its initial state under its own restoring force. This can ensure that the part of the filter belt 5 away from the dust collection hood 72 does not allow external air to pass through, making it easier for the scraper 61 to scrape off the dust particles on the filter belt 5. When the scraper 61 scrapes off the dust particles on the filter belt 5, the collection box 6 can collect the dust particles scraped off by the scraper 61, thereby realizing the centralized collection of dust particles generated during coal mining operations. To improve the efficiency of the filter belt 5 in filtering dust particles, the filter belt 5 can be made of cotton cloth with a velvety surface. Before the filter belt 5 filters dust particles, the receiving end of the spray head 1 is connected to an external water pump. The external water pump can spray water onto the surface of the filter belt 5 through the spray head 1. When the spray head 1 sprays water onto the surface of the filter belt 5, the velvety surface of the filter belt 5 will be wetted by the water, and a water film will be formed on the surface of the filter belt 5. This can increase the resistance of airflow through the filter belt 5, and at the same time increase the intensity of the filter belt 5 in filtering dust particles, preventing the dust particles filtered by the filter belt 5 from floating in the air again. When the dust hood 72 draws outside air through the moist filter belt 5, the part of the filter belt 5 near the scraper 61 will be in a dry state, which makes it easier for the scraper 61 to scrape off the dust particles on the filter belt 5. As the filter belt 5 rotates, the filter belt 5 with scraped dust particles will enter the interior of the inner shell 7. Since the connecting shell 76 is fixed at equal intervals on the drive column 75, and the impact block 74 slides on the connecting shell 76, when the drive column 75 drives the connecting shell 76 to rotate, the impact block 74 located below will impact the filter belt 5. This will allow the dust particles that the scraper 61 did not scrape to fall into the second collection port 63, so that the collection box 6 can collect the dust particles on the filter belt 5 again. When the scraper 61 scrapes away the dust particles on the filter belt 5, the fibers on the filter belt 5 may stick together. In order to restore the sticky fibers to their initial state and restore the filtering effect of the fibers on the dust particles, the output shaft of the drive motor 41 can drive the cleaning roller 21 in the dust collection box 2 to comb the fibers on the filter belt 5. The cleaning roller 21 is a columnar structure with bristles on its surface. In actual use, the bristles on the cleaning roller 21 can comb the fibers on the filter belt 5, which makes it easier for the fibers on the filter belt 5 to filter the dust particles in the future. The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
