Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a vibrating baghouse dust collector. Background Technology

[0002] A vibratory dust collector is a baghouse dust collector that uses a mechanical device to vibrate and clean the filter bags. It is generally called a dust collector bag or dust filter bag. The filter bag is a key component in the operation of a baghouse dust collector. Typically, cylindrical filter bags are suspended vertically inside the dust collector, and the baghouse dust collector uses an air jet device to vibrate and clean the bags.

[0003] Chinese Patent CN210302977U discloses a vibratory baghouse dust collector, comprising a sleeve, a main body fixedly fitted onto the outer wall of the sleeve, an inlet fixedly connected to one side of the main body, a spiral baffle fixedly fitted onto the lower outer wall of the sleeve and fixedly connected to the interior of the main body, a filter bag fixedly fitted into the middle of the interior of the sleeve, and an air jet device fixedly connected to the upper side of the main body near the inlet. This vibratory baghouse dust collector, through the cooperation of the air jet device and elastic support, can enhance the cleaning effect on the inside of the filter bag through vibration and blowing. The spiral baffle causes the exhaust gas to flow along the outer wall of the aluminum sleeve, thereby transferring heat to the filter bag and evaporating the moisture absorbed by the bag, eliminating the need for frequent filter bag replacement by operators and simplifying operation. The cooperation of the hood and fan blades increases the power of the exhaust gas to drive the fan blades, thus replacing the need for a motor drive.

[0004] The aforementioned patented vibrating bag filter, in actual use, cleans dust from the surface of the filter bag using a single jet device, which has a small cleaning range and results in poor cleaning efficiency; therefore, it does not meet the existing needs. In response, we have proposed a vibrating bag filter. Utility Model Content

[0005] The purpose of this utility model is to provide a vibrating bag filter dust collector, which solves the problem mentioned in the background art that the vibrating bag filter dust collector cleans the dust on the surface of the bag through a single air jet device, which has a small cleaning range and results in poor cleaning efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibrating bag filter, comprising a device housing, an internal dustproof plate, a bag filter sleeve mounted on the lower end of the dustproof plate, a movable frame fixedly mounted below the bag filter sleeve, and a fixing ring mounted on the upper end of the bag filter sleeve. A rubber elastic tube and a spring are provided between the fixing ring and the bag filter sleeve. A rotating shaft is mounted on one end of the movable frame, and a motor is mounted on one end of the rotating shaft. A rocker arm, a rack, and a reciprocating gear are installed between the motor and the rotating shaft.

[0007] Preferably, an air inlet is provided on one side of the outer side of the device housing, a baffle is installed on one side of the air inlet, and a dust collection hopper is provided at the lower end of the baffle.

[0008] Preferably, an exhaust pipe is installed at the upper end of the device housing, and a plurality of air outlets are provided on the surface of the dustproof plate, the positions of which correspond to the positions of the bag filter sleeve.

[0009] Preferably, an air jet pipe is provided above the dustproof plate, and an electromagnetic pulse valve is installed at the rear end of the air jet pipe. The air jet pipe is used to introduce compressed air into the sleeve of the bag filter.

[0010] Preferably, the lower end of the bag filter sleeve is fixedly connected to an air inlet base, and the upper end of the movable frame is fixedly connected to a connecting arm, which is fixedly connected to the air inlet base.

[0011] Preferably, the rotating shaft and the movable frame are fixedly connected by a coupling, a fixed frame is provided on one side of the movable frame, and the rotating shaft is rotatably connected to the fixed frame through a bearing.

[0012] Preferably, the two ends of the rubber elastic tube and the spring are fixedly connected to the bag filter sleeve and the fixing ring, respectively. An inner filter bag is provided inside the bag filter sleeve. An exhaust port is provided above the inner filter bag. The exhaust port is connected to the air outlet. The upper end of the inner filter bag is connected to the dustproof plate through a spring rod.

[0013] Preferably, the output shaft of the motor is fixedly connected to one end of the rocker arm, the other end of the rocker arm is embedded inside the limiting ring and slidably connected to the limiting ring, the limiting ring is fixedly connected to the rack, the rear end of the rack is provided with a fixed guide rail, the fixed guide rail is fixedly connected to the device housing, the rack is meshed with a reciprocating gear, and the reciprocating gear is fixedly connected to the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In the air intake process, this utility model drives the rocker arm to rotate via an electric motor. One end of the rocker arm slides on a limiting ring, causing the limiting ring to be simultaneously affected by the fixed guide rail and the rocker arm. This causes the rack to move back and forth horizontally, which in turn drives the reciprocating gear to rotate at a small angle. During the rotation of the reciprocating gear, the rotating shaft and the movable frame rotate slightly. During the movement of the movable frame, the bag filter sleeve moves, allowing the bag filter sleeve and the inner filter bag to swing. Combined with the exhaust pipe, this allows for a wide range of air vibration, thoroughly shaking off the dust on the surface of the inner filter bag, improving the cleaning effect, increasing efficiency, and facilitating long-term operation. Furthermore, the fixing ring at the upper end of the bag filter sleeve, combined with a rubber elastic tube, maintains the sealing effect between the bag filter sleeve and the dustproof plate. The bag filter sleeve and the inner filter bag are promptly reset by springs and spring rods, resulting in a stable structure and better cleaning effect.

[0016] 2. This utility model introduces waste gas into the device housing through the air inlet. After entering the housing, the waste gas is blocked by a dustproof plate and flows around the dust collection hopper. Large dust particles fall directly to the bottom of the dust collection hopper due to inertia and gravity. The gas passes below the bag filter sleeve and is adsorbed by the inner filter bags inside the sleeve. After long-term operation, dust accumulates on the surface of the inner filter bags. By opening the electromagnetic pulse valve, compressed air is introduced through the jet pipe and rapidly expands in the device housing in a very short time. This expands and vibrates the inner filter bags, causing them to expand and deform. Under the action of the reverse airflow, the dust adhering to the outer surface of the inner filter bags is peeled off and falls into the dust collection hopper. The structure is compact and convenient for long-term use. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] To address the issue of poor cleaning efficiency in existing vibratory baghouse dust collectors due to the limited cleaning area caused by a single air jet device used to clean dust from the bag surface, please refer to [link to relevant documentation]. Figure 1 - Figure 5 This embodiment provides the following technical solution:

[0025] This embodiment of a vibrating bag filter includes a housing 1. A dustproof plate 101 is installed inside the housing 1. A bag filter sleeve 3 is installed at the lower end of the dustproof plate 101. A movable frame 301 is fixedly installed below the bag filter sleeve 3, and a fixing ring 306 is installed at the upper end of the bag filter sleeve 3. A rubber elastic tube 308 and a spring 309 are provided between the fixing ring 306 and the bag filter sleeve 3. A rotating shaft 303 is installed at one end of the movable frame 301, and a motor 4 is installed at the other end of the rotating shaft 303. A rocker arm 404, a rack 402, and a reciprocating gear 403 are installed between the rotating shaft 303 and the rotating shaft 303. The rotating shaft 303 is fixedly connected to the movable frame 301 through a coupling. A fixed frame 302 is provided on one side of the movable frame 301. The rotating shaft 303 is rotatably connected to the fixed frame 302 through a bearing. During the rotation of the reciprocating gear 403, the rotating shaft 303 and the movable frame 301 are driven to rotate slightly. During the movement of the movable frame 301, the bag filter sleeve 3 is driven to move, thereby allowing the bag filter sleeve 3 and the inner filter bag 310 to swing.

[0026] In addition, the lower end of the bag filter sleeve 3 is fixedly connected to the air inlet base 305, and the upper end of the movable frame 301 is fixedly connected to the connecting arm 304, which is fixedly connected to the air inlet base 305.

[0027] It should be noted that the two ends of the rubber elastic tube 308 and the spring 309 are fixedly connected to the bag filter sleeve 3 and the fixing ring 306, respectively. The bag filter sleeve 3 is equipped with an inner filter bag 310. An exhaust port 307 is provided above the inner filter bag 310. The exhaust port 307 is connected to the air outlet 102. The upper end of the inner filter bag 310 is connected to the dustproof plate 101 through the spring rod. With the help of the exhaust pipe 103, a wide range of air vibration can be performed, so that the dust on the surface of the inner filter bag 310 is fully shaken off, improving the cleaning effect, efficiency, and long-term operation. In addition, the fixing ring 306 at the upper end of the bag filter sleeve 3, together with the rubber elastic tube 308, maintains the sealing effect between the bag filter sleeve 3 and the dustproof plate 101. The bag filter sleeve 3 and the inner filter bag 310 are promptly reset by the spring 309 and the spring rod, resulting in a stable structure and better cleaning effect.

[0028] The output shaft of the motor 4 is fixedly connected to one end of the rocker arm 404, and the other end of the rocker arm 404 is embedded in the limiting ring 401 and slidably connected to the limiting ring 401. The limiting ring 401 is fixedly connected to the rack 402, and the rear end of the rack 402 is provided with a fixed guide rail 405. The fixed guide rail 405 is fixedly connected to the device housing 1, and the rack 402 is meshed with the reciprocating gear 403. The reciprocating gear 403 is fixedly connected to the rotating shaft 303. During the air intake process, the motor 4 drives the rocker arm 404 to rotate, and one end of the rocker arm 404 slides on the limiting ring 401, so that the limiting ring 401 is simultaneously affected by the fixed guide rail 405 and the rocker arm 404, which drives the rack 402 to move back and forth horizontally, thereby driving the reciprocating gear 403 to rotate back and forth at a small angle.

[0029] Specifically, during the air intake process, the rocker arm 404 is driven to rotate by the motor 4. One end of the rocker arm 404 slides on the limiting ring 401, causing the limiting ring 401 to be simultaneously affected by the fixed guide rail 405 and the rocker arm 404. This causes the rack 402 to move back and forth horizontally, which in turn drives the reciprocating gear 403 to rotate back and forth at a small angle. During the rotation of the reciprocating gear 403, the rotating shaft 303 and the movable frame 301 rotate slightly. During the movement of the movable frame 301, the bag filter sleeve 3 moves, thereby removing dust from the bag filter. The sleeve 3 and the inner filter bag 310 swing together, and with the exhaust pipe 103, a wide range of air vibration can be performed, which can fully shake off the dust on the surface of the inner filter bag 310, improve the cleaning effect, and have high efficiency, which is conducive to long-term operation. In addition, the fixing ring 306 at the upper end of the bag dust collector sleeve 3, together with the rubber elastic tube 308, maintains the sealing effect between the bag dust collector sleeve 3 and the dustproof plate 101. The bag dust collector sleeve 3 and the inner filter bag 310 are promptly reset by the spring 309 and the spring rod, resulting in a stable structure and better cleaning effect.

[0030] To address the issues of existing vibratory baghouse dust collectors, such as their simple structure, inconvenient bag cleaning, and impeded continuous operation, please refer to [the relevant documentation / reference]. Figure 1 - Figure 5 This embodiment provides the following technical solution:

[0031] An air inlet 106 is provided on one side of the outer casing 1 of the device in this embodiment. A baffle 105 is installed on one side of the air inlet 106. A dust collection hopper 104 is provided at the lower end of the baffle 105. The air inlet 106 introduces the exhaust gas into the device casing 1. After entering the device casing 1, the exhaust gas is blocked by the dustproof plate 101. The exhaust gas flows around the dust collection hopper 104. Large dust particles fall directly into the bottom of the dust collection hopper 104 due to inertia and gravity.

[0032] The upper end of the housing 1 is equipped with an exhaust pipe 103, and the surface of the dustproof plate 101 is provided with several air outlets 102. The positions of the air outlets 102 correspond to the positions of the bag filter sleeve 3. The cleaned air is discharged through the air outlets 102 and the exhaust pipe 103.

[0033] Furthermore, an air jet pipe 2 is provided above the dustproof plate 101, and an electromagnetic pulse valve 201 is installed at the rear end of the air jet pipe 2. The air jet pipe 2 is used to introduce compressed air into the bag filter sleeve 3. The gas passes below the bag filter sleeve 3 and adsorbs dust through the inner filter bag 310 inside the bag filter sleeve 3. After long-term operation, dust accumulates on the surface of the inner filter bag 310. By opening the electromagnetic pulse valve 201, compressed air is introduced through the air jet pipe 2 and rapidly expands in the device housing 1 in a very short time, rushing into the inner filter bag 310, causing the inner filter bag 310 to expand, deform and vibrate. Under the action of the reverse airflow, the dust attached to the outer surface of the inner filter bag 310 is peeled off and falls into the dust collection hopper 104. The structure is compact and easy to use.

[0034] Specifically, the air inlet 106 guides the exhaust gas into the device housing 1. After entering the device housing 1, it is blocked by the dustproof plate 101. The exhaust gas flows around the dust collection hopper 104. Large dust particles fall directly into the bottom of the dust collection hopper 104 due to inertia and gravity. The gas passes under the bag filter sleeve 3 and is adsorbed by the inner filter bag 310 inside the bag filter sleeve 3. After long-term operation, dust accumulates on the surface of the inner filter bag 310. By opening the electromagnetic pulse valve 201, compressed air is introduced through the jet pipe 2 and rapidly expands in the device housing 1 in a very short time. It rushes into the inner filter bag 310, causing the inner filter bag 310 to expand, deform and vibrate. Under the action of the reverse airflow, the dust attached to the outer surface of the inner filter bag 310 is peeled off and falls into the dust collection hopper 104, which is convenient for long-term use.

[0035] Working principle: During use, the exhaust gas is introduced into the housing 1 through the inlet 106. After entering the housing 1, it is blocked by the dustproof plate 101. The exhaust gas flows around the dust collection hopper 104. Large dust particles fall directly to the bottom of the dust collection hopper 104 due to inertia and gravity. The gas passes under the bag filter sleeve 3 and is adsorbed by the inner filter bag 310 inside the bag filter sleeve 3. After long-term operation, dust accumulates on the surface of the inner filter bag 310. This can be removed by activating the electromagnetic pulse. The valve 201 introduces compressed air through the jet pipe 2, which rapidly expands within the device housing 1 in a very short time. This air rushes into the inner filter bag 310, causing it to expand, deform, and vibrate. Under the scouring action of the reverse airflow, dust adhering to the outer surface of the inner filter bag 310 is peeled off and falls into the dust collection hopper 104. During the air intake process, the motor 4 drives the rocker arm 404 to rotate. One end of the rocker arm 404 slides against the limiting ring 401, causing the limiting ring 401 to simultaneously... Influenced by the fixed guide rail 405 and the rocker arm 404, the rack 402 moves horizontally back and forth, which in turn drives the reciprocating gear 403 to rotate at a small angle. During the rotation of the reciprocating gear 403, the rotating shaft 303 and the movable frame 301 rotate slightly. During the movement of the movable frame 301, the bag filter sleeve 3 moves, which allows the bag filter sleeve 3 and the inner filter bag 310 to swing. Combined with the exhaust pipe 103, this enables a wide range of air vibration. This allows the dust on the surface of the inner filter bag 310 to be fully shaken off, improving the cleaning effect and efficiency, which is beneficial for long-term operation. In addition, the fixing ring 306 at the upper end of the bag dust collector sleeve 3, together with the rubber elastic tube 308, maintains the sealing effect between the bag dust collector sleeve 3 and the dustproof plate 101. The bag dust collector sleeve 3 and the inner filter bag 310 are promptly reset by the spring 309 and the spring rod, resulting in a stable structure and better cleaning effect. The cleaned air is discharged through the air outlet 102 and the exhaust pipe 103.
