Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to an energy-saving pulse vibration dust removal device. Background Technology

[0002] Pulse jet dust collectors, also known as pulse dust collectors, are high-efficiency dust removal devices that use pulse jet technology to remove dust from filter bags. Pulse dust collectors have advantages such as high dust removal efficiency, large gas handling capacity, stable and reliable operation, convenience and energy saving, and are widely used in dust removal in industries such as power, metallurgy, building materials, and chemicals.

[0003] In existing energy-saving pulse-jet dust collectors, dusty gas is introduced into the machine through pipelines. The dust particles are then trapped on the surface of the filter bags, while clean gas passes through the filter bags into the clean air chamber and is finally discharged by the induced draft fan. When the dust on the surface of the filter bags accumulates to a certain level, the pulse valve opens, and compressed air is injected into the filter bags through the blowpipe. This causes the filter bags to expand rapidly and generate strong vibrations, which shake off the dust adhering to the surface of the filter bags into the dust hopper, thus achieving dust collection and treatment.

[0004] However, when the pulse valve injects compressed air into the filter bag, some airflow may leak out and be blown into the dust hopper, causing the dust in the dust hopper to float due to the airflow, resulting in dirt and mess inside the machine and affecting the dust collection efficiency. Utility Model Content

[0005] The technical problem this invention aims to solve is that when the pulse valve injects compressed air into the filter bag, some of the airflow may leak out and be blown into the ash hopper, causing the dust in the ash hopper to float due to the airflow, resulting in dirt and mess inside the machine and affecting the dust collection efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: an energy-saving pulse vibration dust removal device, including a body, which is placed on the ground as an integral support structure; a filter bag, which is installed inside the body, wherein the filter bag is used to carry dusty gas and filter the dust in the dusty gas; a pulse valve, which is installed on one side of the body, wherein the pulse valve injects airflow into the filter bag, causing the filter bag to expand rapidly and generate strong vibration, shaking the dust into the ash hopper for collection; an induced draft fan, which is installed in the clean air chamber at the top of the body, wherein the induced draft fan introduces clean gas from the filter bag into the clean air chamber and discharges it; and a detachable humidifying device, which is installed inside the body, wherein the humidifying device is placed between the ash hopper and the filter bag, and wets the dust by atomizing water and sprinkling it into the ash hopper, preventing the dust from floating.

[0007] Preferably, the dehumidifying device includes: a frame, wherein the frame is detachably installed inside the machine body via a connecting assembly; a water inlet pipe, wherein the water inlet pipe is threadedly connected to a bidirectional screw via a screw hole block, wherein the bidirectional screw is placed inside the frame and driven by a motor, wherein the surface thread shape of the bidirectional screw is arranged in opposite symmetrical patterns; and an atomizing tube, wherein a gear ring is fixedly connected to one side of the atomizing tube, wherein the gear ring is rotatably connected to the water inlet pipe via a bearing seal ring, wherein the gear ring is placed inside the gear rod and meshes with the gear rod.

[0008] The effect achieved by the above components is as follows: By setting up a humidification device, the external water pipe is first connected to the inlet pipe. Then, the motor drives the bidirectional screw to rotate, causing the bidirectional screw to drive the two inlet pipes to move in opposite directions along the surface of the bidirectional screw through the screw hole block. This causes the two inlet pipes to drive the two gear rings to move along the inside of the gear rack. Under the action of the gear rings meshing with the gear rack, the two gear rings drive the atomizing tube to move left and right and rotate during the movement. At this time, the water source enters the atomizing tube through the inlet pipe and the gear rings and is sprayed out in a mist. The rotation of the atomizing tube increases the spraying range and makes the spray more uniform due to inertia and rotation. This allows the sprayed atomized water to evenly disperse into the ash hopper, wetting the dust inside and causing it to clump together and increase its weight. This prevents the dust from floating and reduces the amount of dust blown up by the airflow, which would otherwise float inside the machine and adhere to the inner wall, causing internal dirt and affecting dust collection efficiency. This improves the efficiency of dust collection and treatment.

[0009] Preferably, the wetting device further includes a circular block, wherein the circular block is fixed to the end of the atomizing tube away from the gear ring, and wherein the circular block is placed inside the frame to support and limit the side of the atomizing tube away from the gear ring.

[0010] The effect achieved by the above components is that by setting up the circular block, the circular block can move along the inside of the frame and support and reinforce the atomizing tube, reducing the shaking of the atomizing tube on the side away from the gear ring.

[0011] Preferably, the damping device further includes a baffle, which is fixed to the inside of the frame, wherein the surface of the baffle is larger than that of the atomizing tube, and the baffle is positioned above the atomizing tube to intercept scattered dust.

[0012] The effect achieved by the above components is as follows: by setting up a baffle, the atomizing tube can be moved under the baffle when not in use, so that the baffle can intercept scattered dust or grime, reducing the accumulation of dust and grime on the surface of the atomizing tube when it is not in use, and preventing clogging.

[0013] Preferably, the surface of the baffle is provided with an angle, wherein the angle has a certain slope to make it easier for dust to roll off.

[0014] The effect achieved by the above components is that by opening an angle on the baffle, the surface of the baffle has a certain slope, which reduces the excessive accumulation of dust on the baffle.

[0015] Preferably, the wetting device further includes a handle, which is fixed to the frame, wherein the inner side of the handle is provided with a plurality of anti-slip protrusions.

[0016] The effect achieved by the above components is that by setting handles, a point of leverage can be provided for personnel, improving the convenience and stability of manually pulling the frame.

[0017] Preferably, the connecting assembly includes: a sleeve fixedly connected to the machine body, wherein the inner wall of the sleeve is connected to the inner wall of the machine body, and wherein the frame is slidably connected to the sleeve; a spring rod slidably mounted on the sleeve, wherein the other end of the spring rod is fixedly connected to the sleeve; and a circular hole plate fixedly connected to the frame, wherein the spring rod is inserted into the circular hole plate under the push of the spring to fix the frame.

[0018] The effect achieved by the above components is as follows: by setting the connecting components, the frame is first moved manually, causing the frame to move the perforated plate. When the frame moves to the position where it is fully inserted into the sleeve, the hole on the perforated plate corresponds to the position of the spring rod. Under the reaction force of the spring in the spring rod, the spring rod moves towards the perforated plate, so that the spring rod is inserted into the perforated plate to limit the frame. This achieves convenient installation between the dehumidifying device and the machine body, and at the same time, it allows for convenient disassembly of the dehumidifying device in the future, improving the flexibility of the dehumidifying device and the convenience of later maintenance.

[0019] Preferably, the connecting assembly further includes a support plate, wherein the support plate is fixedly installed between the sleeve and the machine body to support and reinforce the sleeve.

[0020] The effect achieved by the above components is that by setting up a support plate, the support plate can increase the connection strength between the sleeve and the machine body, and at the same time support the sleeve and increase its stability.

[0021] The beneficial effects of this utility model are:

[0022] By installing a humidifying device, the dust in the ash hopper can be moistened, reducing the amount of dust blown up by the airflow. This prevents the dust from floating inside the machine and adhering to the inner wall, causing the machine to become dirty and affecting dust collection efficiency, thus improving the efficiency of dust collection and treatment.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figure 1-4 The energy-saving pulse-jet dust collector shown includes a body 1, which is placed on the ground as a supporting structure; filter bags 3, which are installed inside the body 1 and are used to carry dusty gas and filter the dust in the gas; a pulse valve 2, which is installed on one side of the body 1 and injects airflow into the filter bags 3, causing the filter bags 3 to expand rapidly and generate strong vibration, shaking the dust into the dust hopper 5 for collection; an induced draft fan 4, which is installed in the clean air chamber at the top of the body 1 and introduces clean gas from the filter bags 3 into the clean air chamber and discharges it; and a detachable humidifying device 6, which is installed inside the body 1 and is placed between the dust hopper 5 and the filter bags 3. The humidifying device 6 wets the dust by atomizing water and sprinkling it into the dust hopper 5, preventing the dust from floating.

[0032] Figure 2 and Figure 3The humidifying device 6 shown includes: a frame 61, which is detachably installed inside the body 1 via a connecting assembly 7; a water inlet pipe 66, which is threadedly connected to a bidirectional screw 65 via a screw hole block, wherein the bidirectional screw 65 is located inside the frame 61 and driven by a motor, and the surface thread shape of the bidirectional screw 65 is arranged in opposite symmetrical patterns; and an atomizing tube 68, on one side of which a gear ring 67 is fixedly connected, wherein the gear ring 67 is rotatably connected to the water inlet pipe 66 via a bearing seal ring, wherein the gear ring 67 is located inside a gear rack 62 and meshes with the gear rack 62. By setting up the humidifying device 6, the external water pipe is first connected to the water inlet pipe 66, and then the bidirectional screw 65 is driven to rotate by a motor, so that the bidirectional screw 65 drives the two water inlet pipes 66 to move in opposite directions along the surface of the bidirectional screw 65 via the screw hole block, so that the two water inlet pipes 66 drive the two... The gear ring 67 moves along the inside of the rack 62. Under the action of the gear ring 67 meshing with the rack 62, the two gear rings 67 drive the atomizing tube 68 to move left and right and rotate during the movement. At this time, the water source enters the atomizing tube 68 through the water inlet pipe 66 and the gear ring 67 and is sprayed out in a mist. At the same time, under the action of the rotation of the atomizing tube 68, the sprayed mist water increases the spraying range under the action of inertia and rotation, and the spraying is more uniform. The sprayed atomized water is evenly scattered into the ash hopper 5, wetting the dust inside and causing the dust to condense and increase its weight. This achieves the anti-floating treatment of dust and reduces the situation where some airflow blows up the dust in the ash hopper 5, causing the dust in the ash hopper 5 to float inside the machine body 1 and adhere to the inner wall of the machine body 1, making the inside of the machine body 1 dirty and affecting the dust collection efficiency. This improves the dust collection and treatment efficiency.

[0033] Figure 2 and Figure 3 The humidifying device 6 also includes a circular block 69, which is fixedly connected to the end of the atomizing tube 68 away from the gear ring 67. The circular block 69 is placed inside the frame 61 to support and limit the side of the atomizing tube 68 away from the gear ring 67. By setting the circular block 69, the circular block 69 can move along the inside of the frame 61 to support and reinforce the atomizing tube 68, reducing the shaking of the side of the atomizing tube 68 away from the gear ring 67. The humidifying device 6 also includes a baffle 64, which is fixedly connected to the inside of the frame 61. The surface of the baffle 64 is larger than that of the atomizing tube 68. The baffle 64 is placed above the atomizing tube 68 to intercept scattered dust. By setting the baffle 64, the atomizing tube 68 can move below the baffle 64 when not in use, so that the baffle 64 can intercept scattered dust or ash, reducing the accumulation of dust and ash on the surface of the atomizing tube 68 when not in use and preventing blockage.

[0034] Figure 2 and Figure 3The baffle 64 shown has an angled surface with a certain slope to make it easier for dust to roll off. By opening the angled surface of the baffle 64, the surface of the baffle 64 has a certain slope, which reduces the excessive accumulation of dust on the baffle 64. The wetting device 6 also includes a handle 63, which is fixed to the frame 61. The inner side of the handle 63 has multiple anti-slip protrusions. By setting the handle 63, a point of leverage can be provided for personnel, improving the convenience and stability of personnel manually pulling the frame 61.

[0035] Figure 3 and Figure 4 The connecting assembly 7 shown includes: a sleeve 71, which is fixedly connected to the body 1, wherein the inner wall of the sleeve 71 is connected to the inner wall of the body 1, and the frame 61 is slidably connected to the sleeve 71; a spring rod 72, which is slidably mounted on the sleeve 71, and the other end of the spring rod 72 is fixedly connected to the sleeve 71; and a circular hole plate 74, which is fixedly connected to the frame 61, wherein the spring rod 72 is inserted into the circular hole plate 74 under the push of the spring to fix the frame 61. By setting the connecting assembly 7, the frame 61 can be manually moved first, so that the frame... The frame 61 moves the perforated plate 74. When the frame 61 moves to the position where it is fully inserted into the sleeve 71, the hole on the perforated plate 74 corresponds to the position of the spring rod 72. Under the reaction force of the spring in the spring rod 72, the spring rod 72 moves towards the perforated plate 74, so that the spring rod 72 is inserted into the perforated plate 74 to limit the frame 61. This achieves convenient installation between the dehumidifying device 6 and the machine body 1, and at the same time, it allows for convenient disassembly of the dehumidifying device 6 in the future, improving the flexibility of use of the dehumidifying device 6 and the convenience of later maintenance.

[0036] Figure 3 and Figure 4 The connecting assembly 7 shown also includes a support plate 73, wherein the support plate 73 is fixedly installed between the sleeve 71 and the body 1 to support and reinforce the sleeve 71. By setting the support plate 73, the support plate 73 can increase the connection strength between the sleeve 71 and the body 1, and at the same time support the sleeve 71 to increase the stability of the sleeve 71.

[0037] Working principle: First, dusty gas is introduced into the machine body 1 through a pipeline. Then, the dust particles are trapped on the surface of the filter bag 3 through the filtration effect of the filter bag 3, while the clean gas enters the clean air chamber through the filter bag 3 and is finally discharged by the induced draft fan 4. When the dust on the surface of the filter bag 3 accumulates to a certain level, the pulse valve 2 opens, and compressed air is injected into the interior of the filter bag 3 through the blow pipe, causing the filter bag 3 to expand rapidly and generate strong vibration, thereby shaking off the dust attached to the surface of the filter bag 3 into the dust hopper 5, realizing the collection and treatment of dust.

[0038] First, manually move the frame 61 so that the frame 61 moves the perforated plate 74. When the frame 61 moves to the position where it is fully inserted into the sleeve 71, the hole on the perforated plate 74 corresponds to the position of the spring rod 72. Under the reaction force of the spring in the spring rod 72, the spring rod 72 moves towards the perforated plate 74, so that the spring rod 72 is inserted into the perforated plate 74 to limit the frame 61, thereby achieving convenient installation between the wettability device 6 and the body 1.

[0039] At this point, the external water pipe is connected to the inlet pipe 66. Then, the motor drives the bidirectional screw 65 to rotate, causing the two inlet pipes 66 to move opposite each other along the surface of the bidirectional screw 65 through the screw hole block. This causes the two inlet pipes 66 to drive the two gear rings 67 to move along the inside of the gear rack 62. Under the action of the gear rings 67 meshing with the gear rack 62, the two gear rings 67 drive the atomizing tube 68 to move left and right and rotate during the movement. At this time, the water source enters the atomizing tube 68 through the inlet pipe 66 and the gear rings 67 and is sprayed out in a mist. At the same time, under the action of the rotation of the atomizing tube 68, the sprayed mist water increases the spray range and sprays more evenly under the action of inertia and rotation. This allows the sprayed atomized water to fall evenly into the ash hopper 5, wetting the dust inside and causing the dust to condense and increase its weight, thereby achieving the anti-floating treatment of the dust.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
