Description

Technical Field

[0001] This invention belongs to the field of dust removal equipment technology, and specifically relates to an industrial dust removal device that is easy to clean. Background Technology

[0002] Baghouse dust collectors are suitable for collecting fine, dry, non-fibrous dust. When gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the dust hopper. As the gas passes through the filter bags, the dust is blocked and filtered, purifying the gas. The filter bags are typically cleaned by compressed air pulse-jet cleaning. The cleaning mechanism consists of an air tank, a blowpipe, and an electromagnetic pulse control valve. During cleaning, the electromagnetic valve opens the pulse valve, and compressed air is injected through the nozzles on the blowpipe according to a set program. The compressed gas passes through each pulse valve in sequence for a very short time, inducing several times the volume of air to enter the filter bags, forming an air wave. This causes the filter bags to expand rapidly from the opening to the bottom, resulting in a strong cleaning effect and shaking off the dust from the filter bags.

[0003] Existing belt dust collectors have the following shortcomings in practical use: First, during filtration, fine dust adheres to the surface of the filter bags, causing a continuous decline in filtration efficiency and requiring frequent cleaning. Cleaning necessitates stopping the machine and focusing on cleaning the filter bags, significantly reducing dust collection efficiency. Furthermore, the dust generated during backflushing can permeate the entire dust collection chamber due to airflow, making it difficult to clean. Additionally, the backflushing device complicates the dust collection system's structure, occupies a large amount of space, increases operating costs, and hinders maintenance.

[0004] Therefore, in view of the above-mentioned shortcomings, this application proposes an easy-to-clean industrial dust removal device that can effectively solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an easy-to-clean industrial dust removal device, thereby effectively solving the problems existing in the prior art.

[0006] To achieve the above objectives, the specific technical solution of the present invention is as follows:

[0007] An easy-to-clean industrial dust removal device includes a dust collection box, a dust collection device fixedly connected to the lower end of the dust collection box, a fixing device fixedly connected to the connection between the dust collection box and the dust collection device, an exhaust chamber device provided on the upper plate of the dust collection box, and vertically distributed filter bags provided between the fixing device and the exhaust chamber device. Vibration devices are connected to the filter bags and are evenly arranged in the vertical direction. The vibration devices can vibrate the filter bags at a specified frequency to shake off the dust attached to the filter bags in real time.

[0008] As a further provision of the above scheme, the dust collection device is provided with an air intake device, which includes an air intake chamber. The air intake chamber is fixedly installed inside the dust collection device and is not connected to the dust collection device. The air intake chamber is provided with an air inlet.

[0009] As a further provision of the above solution, the fixing device includes a first fixing plate and a second fixing plate, with the second fixing plate located on both sides of the first fixing plate. The first fixing plate and the second fixing plate separate the dust collector and the dust collection device. The first fixing plate and the second fixing plate have evenly distributed dust collection holes, which are staggered and fixedly connected to the lower end of the bag filter device. Symmetrical ventilation pipes are fixedly connected to both sides of the first fixing plate. The ventilation pipes pass through the first fixing plate and are parallel to the bag filter device. The lower end of the ventilation pipes is connected to the air inlet chamber.

[0010] As a further provision of the above scheme, the exhaust chamber device includes an exhaust chamber with a through hole on its lower end face. The through hole is fixedly connected to the upper end of the bag filter device. The exhaust chamber is isolated from the dust collector housing and is connected to the bag filter device. An installation platform is provided inside the exhaust chamber. A spring device is fixedly installed inside the installation platform. The upper end of the spring device is connected to a guide platform. The guide platform is fixedly installed on the upper plate. An air outlet device is provided at the center of the upper plate.

[0011] As a further provision of the above solution, the mounting platform is connected to a cylinder device, which includes a cylinder and a telescopic rod. The cylinder is fixedly mounted on the upper plate, and the telescopic rod is fixedly connected to the mounting platform. In its natural state, the telescopic rod does not provide load to the mounting platform.

[0012] As a further provision of the above scheme, the vibration device includes a support plate and a drive motor. The support plate has mounting holes that are connected to the bag filter device. One end of the support plate is rotatably connected to the inner wall of the dust collector, and the other end of the support plate is provided with a fixing plate. The fixing plate is fixedly installed on the dust collector. The fixing plate is provided with a bearing device, and the support plate is rotatably connected to the bearing device. A connecting arm is connected to the end of the support plate near the bearing device.

[0013] As a further feature of the above solution, the drive motor is fixedly installed on the side wall of the dust collector box. The drive motor is connected to a pulley device, which is rotatably connected to the middle of the side wall of the dust collector box. A swing block is symmetrically installed on the pulley device along the axis. A connecting frame is hinged to the swing block. The connecting frame is also hinged to the connecting arm. The drive motor rotates back and forth, driving the connecting frame to move back and forth through the pulley device and the swing block. The connecting frame drives the support plate to swing back and forth.

[0014] The beneficial effects of this invention are:

[0015] During operation, the lower end of the bag filter is fixed to the fixing device, and the upper end is fixed to the exhaust chamber device. The spring device is in an extended state, applying an upward pulling force to the exhaust chamber device. The mounting platform and guide platform cooperate to ensure that the bag filter is in a taut, vertical state. The cylinder adjusts the height of the exhaust chamber device via a telescopic rod, thereby adjusting the tension of the bag filter. During dust removal, dust-laden air enters the inlet chamber through the air inlet. The air passes through the ventilation pipe, through the first fixing plate, and enters the upper part of the dust collector. At this time, the dust collector and dust collection device are under positive pressure. The air passes through the bag filter and rises into the exhaust chamber, finally exiting from the outlet device. As the air passes through the bag filter, dust is blocked and filtered onto the surface of the bag filter. During the filtration process, the drive motor reciprocates in both forward and reverse directions at a certain frequency and small angle. Through the pulley device and the swing block, the connecting frame moves back and forth, and the connecting frame drives the support plate to swing back and forth. Since the support plate is connected to the bag filter through the mounting hole, the swing of the support plate causes the entire bag filter to move in the same direction. The vibration shakes off the dust adhering to the filter bag, preventing excessive dust accumulation from affecting the filtration effect. Simultaneously, the spring mechanism's cushioning effect reduces the risk of the filter bag breaking. After detaching from the filter bag, the dust flows downwards through the dust collection holes into the dust collection device. The ventilation duct design ensures that the airflow within the dust collector flows downwards, facilitating dust entry into the dust collection device and reducing dust dispersion. When a thorough cleaning is required, the cylinder moves the exhaust chamber downwards via the telescopic rod. Once the filter bag loosens, the drive motor rotates in both directions at a greater angle, causing the filter bag to vibrate violently and clean the dust thoroughly.

[0016] This invention cleans dust by installing a fixing device and a bag filter inside the dust collector, and using an exhaust chamber device to maintain the bag filter at an appropriate tightness. A vibration device drives the bag filter to shake, thus achieving the purpose of cleaning dust. The vibration device does not affect the operation of the bag filter during cleaning, and does not require machine shutdown, which greatly improves the dust removal efficiency. In addition, the structure is simple, the equipment has low operating costs, and meets the needs of actual production. Attached Figure Description

[0030] like Figure 6 , Figure 7 , Figure 8 As shown, the fixing device 5 includes a first fixing plate 501 and a second fixing plate 502. The second fixing plate 502 is located on both sides of the first fixing plate 501. The first fixing plate 501 and the second fixing plate 502 separate the dust collector 1 and the dust collection device 2. The first fixing plate 501 and the second fixing plate 502 have evenly distributed dust collection holes 503. The dust collection holes 503 are fixedly connected to the lower end of the bag device 8 in an alternating manner. Symmetrical ventilation pipes 504 are fixedly connected to both sides of the first fixing plate 501. The ventilation pipes 504 pass through the first fixing plate 501 and are parallel to the bag device 8. The lower end of the ventilation pipes 504 is connected to the air inlet chamber 301.

[0031] The exhaust chamber device 6 includes an exhaust chamber 601. The lower end face of the exhaust chamber 601 is provided with a through hole 602, which is fixedly connected to the upper end of the bag filter device 8. The exhaust chamber 601 is isolated from the dust collector box 1 and is connected to the bag filter device 8. An installation platform 603 is provided inside the exhaust chamber 601. A spring device 604 is fixedly installed inside the installation platform 603. The upper end of the spring device 604 is connected to a guide platform 605. The guide platform 605 is fixedly installed on the upper plate 101. An air outlet device 9 is provided at the center of the upper plate 101. The installation platform 603 is connected to a cylinder device 7. The cylinder device 7 includes a cylinder 701 and a telescopic rod 702. The cylinder 701 is fixedly installed on the upper plate 101. The telescopic rod 102 is fixedly connected to the installation platform 603. In its natural state, the telescopic rod 702 does not provide load to the installation platform 603.

[0032] like Figure 4 , Figure 5As shown, the vibration device 4 includes a support plate 401 and a drive motor 406. The support plate 401 has a mounting hole 4011, which is connected to the bag filter device 8. One end of the support plate 401 is rotatably connected to the inner wall of the dust collector 1, and the other end of the support plate 401 is provided with a fixing plate 402. The fixing plate 402 is fixedly installed on the dust collector 1. A bearing device 403 is provided on the fixing plate 402, and the support plate 401 is rotatably connected to the bearing device 403. A connecting arm 404 is connected to the end of the support plate 401 near the bearing device 403. The drive motor 406 is fixedly installed on the side wall of the dust collector 1 and is connected to a pulley device 407. The pulley device 407 is rotatably connected to the middle of the side wall of the dust collector 1. Swing blocks 408 are symmetrically installed on the pulley device 407 along the axis. A connecting frame 405 is hinged to the swing block 408, and the connecting frame 405 is also hinged to the connecting arm 404.

[0033] The working principle of this invention is as follows: During dust removal, air carrying dust enters the inlet chamber 301 through the inlet 302. The air passes through the ventilation pipe 504 and the first fixed plate 501 into the upper part of the dust collector 1. At this time, the dust collector 1 and the dust collection device 2 are under positive pressure. The air passes through the bag filter 8 and enters the exhaust chamber 601, and finally exits from the outlet device 9. When the air passes through the bag filter 8, the dust is blocked and filtered on the surface of the bag filter 8. During the filtration process, the drive motor 406 reciprocates in a small-angle forward and reverse motion at a certain frequency. Through the pulley device 407 and the swing block 408, the connecting frame 405 moves back and forth. The connecting frame 405 drives the support plate 401 to swing back and forth. The support plate 401 is connected to the bag filter 8 through the mounting hole 4011. The support plate 401 swings, causing the entire bag filter device 8 to vibrate synchronously, shaking off the dust attached to the bag filter device 8 and preventing excessive dust accumulation from affecting the filtration effect of the bag filter device 8. At the same time, due to the buffering effect of the spring device 604, the risk of the bag filter device 8 breaking is reduced. After the dust leaves the bag filter device 8, it passes downward through the dust collection hole 503 and enters the dust collection device 2. The setting of the ventilation pipe 504 makes the airflow in the dust collector box 1 flow downward, which is conducive to the dust entering the dust collection device and reduces the degree of dust diffusion. When thoroughly cleaning the dust, the cylinder 701 drives the exhaust chamber 601 to move downward through the telescopic rod 702. After the bag filter device 8 becomes loose, the drive motor 406 increases the angle to rotate forward and reverse, causing the bag filter device 8 to shake violently and clean the dust.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the scope of the invention.
