Description

Technical Field

[0001] This utility model belongs to the field of flue gas filtration technology. Specifically, this utility model relates to a hood-type furnace tail gas treatment device. Background Technology

[0002] The bell-type furnace is a key piece of equipment in the exhaust gas treatment system of an enterprise workshop. Its core function is to collect, guide, and treat dust-containing and harmful gases generated in the workshop through a closed or semi-closed hood structure to meet environmental emission standards and improve the workshop working environment. However, during the filtration process, dust particles gradually adhere to the surface of the filter screen or become embedded inside the filter pores, reducing the effective flow area of ​​the filter screen, increasing resistance, and ultimately leading to filter screen blockage and decreased filtration efficiency.

[0003] Chinese patent (publication number: CN222279287U) discloses a rapid-cooling environmentally friendly hood-type furnace, including a furnace body and a hood. A mounting bracket is fixedly welded to the outer end of the hood, and an exhaust fan is fixedly mounted on the mounting bracket. A hot water tank is fixedly mounted on the top of the furnace body. Two distribution plates are provided and fixedly mounted at both ends of the hot water tank. Multiple heat exchange pipes are fixedly connected between the two distribution plates. A circulating water tank is fixedly mounted on the top of the hot water tank. A micro-circulation pump is fixedly mounted on one end of the circulating water tank, and a circulation pipe connects the micro-circulation pump to the hot water tank. The other end of the circulating water tank is connected to the hot water tank via the same circulation pipe. A heat-conducting plate is embedded in the top of the circulating water tank, and a semiconductor heat sink is fixedly mounted on the top of the heat-conducting plate. Two connecting covers are provided and threadedly mounted to both ends of a filter cartridge. The filter screen of this rapid-cooling environmentally friendly hood-type furnace is prone to clogging. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a hood-type furnace exhaust gas treatment device that can prevent filter clogging. To achieve the above objective, the technical solution adopted by this utility model is as follows: a hood-type furnace exhaust gas treatment device, including an exhaust fan and a hood-type furnace, wherein the exhaust fan outlet is connected to the hood-type furnace, a filter hood is provided inside the hood-type furnace, the filter hood is provided with an anti-clogging structure, and an exhaust port is provided at the top of the hood-type furnace.

[0005] The anti-clogging structure includes a motor, which is located at the top of the bell-shaped furnace. A rotating rod is installed inside the bell-shaped furnace. The rotating rod is connected to the output shaft of the motor. A rotating rod is connected to the rotating rod, and a vibration structure is installed on the rotating rod.

[0006] The vibration structure includes a toggle block, which is mounted on a rotating rod, and the filter cover is provided with protrusions.

[0007] The bottom of the bell-shaped furnace is provided with a discharge pipe, and guide plates are provided at both ends of the discharge pipe.

[0008] The bell-shaped furnace is equipped with a connecting plate, which is connected to the rotating rod via a bearing.

[0009] The filter cover has an overall V-shaped structure, and a rotating bearing is provided at the closed end of the filter cover. The rotating rod is located inside the rotating bearing.

[0010] The protrusions are arranged symmetrically around the filter cover, and the actuating blocks are arranged at equal intervals on the rotating rod.

[0011] A sliding ramp is provided at the corner of the toggle block.

[0012] The technical advantages of this invention are as follows: During use, the exhaust fan is started, pumping the exhaust gas to be treated into the bell-shaped furnace. The exhaust gas diffuses inside the furnace and flows towards the filter hood. As the exhaust gas passes through the V-shaped filter hood, impurities are intercepted on the surface of the filter hood, and clean gas is discharged from the top exhaust port after passing through the filter hood. Then, the motor starts, driving the rotating rod to rotate synchronously. The actuating block on the rotating rod moves with the rotation, and its sliding inclined surface intermittently contacts the protrusions on the filter hood. When in contact, the actuating block pushes the protrusions, causing the filter hood to vibrate. This vibration causes the impurities attached to the surface of the filter hood to fall off. The dislodged impurities are guided to the bottom by gravity, guided through the guide plate to the discharge pipe, and finally discharged from the discharge pipe. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0019] like Figures 1-3 As shown, a bell-type furnace exhaust gas treatment device includes an exhaust fan 1 and a bell-type furnace 2. The exhaust fan 1 outlet is connected to the bell-type furnace 2. A filter hood 3 is installed inside the bell-type furnace 2, and an anti-clogging structure 4 is installed on the filter hood 3. An exhaust port 6 is installed at the top of the bell-type furnace 2. The exhaust fan 1 outlet is connected to the bell-type furnace 2 inlet. The exhaust fan 1 transports the exhaust gas to the bottom of the bell-type furnace 2 through a pipe. The exhaust gas passes through the filter hood 3 inside the bell-type furnace 2 and is then discharged through the exhaust port 6. When filtering the exhaust gas, the filter hood 3 is prone to dust adhesion due to the stickiness of the dust, causing the filter hood 3 to become clogged. The anti-clogging structure 4 can cause the filter hood 3 to vibrate, causing the dust adhering to the filter hood 3 to fall to the bottom of the bell-type furnace 1.

[0020] The anti-clogging structure 4 includes a motor 401, which is located at the top of the bell-shaped furnace 2. A rotating rod 402 is installed inside the bell-shaped furnace 2, and the rotating rod 402 is connected to the output shaft of the motor 401. A rotating rod 403 is connected to the rotating rod 402, and a vibration structure 5 is installed on the rotating rod 403. The motor 401 is fixed at the top of the bell-shaped furnace 2, and the output shaft of the motor 401 is connected to the rotating rod 402. The rotating rod 402 drives the rotating rod 403 to rotate. The rotating rod 403 is positioned directly opposite the filter cover 3, and the vibration structure 5 is installed on the rotating rod 403. When the rotating rod 403 rotates, the vibration structure 5 causes the filter cover 3 to vibrate, and the dust adhering to the filter cover 3 will be shaken off and fall to the bottom of the bell-shaped furnace 1.

[0021] The vibration structure 5 includes a toggle block 501, which is mounted on the rotating rod 403. The filter cover 3 has protrusions 502. The toggle blocks 501 are spaced apart on the rotating rod 403, and the protrusions 502 are spaced apart on the filter cover 3. Both the toggle blocks 501 and the protrusions 502 are cylindrical structures. Rotation of the rotating rod 403 causes the toggle blocks 501 to pass over the protrusions 502. When the toggle blocks 501 pass over the protrusions 502, they press against the protrusions, allowing the toggle blocks 501 to pass through. This causes the filter cover 3 to vibrate, and the vibration of the filter cover 3 shakes off the dust adhering to it.

[0022] The bottom of the bell-type furnace 2 is equipped with a discharge pipe 201, and guide plates 202 are installed at both ends of the discharge pipe 201. The guide plates 202 are inclined, and the smoke and dust will eventually fall onto the guide plates 202. The guide plates 202 guide the smoke and dust into the discharge pipe 201. The valve on the discharge pipe 4 can be opened periodically for cleaning.

[0023] A connecting plate 7 is installed inside the bell-type furnace 2, and the connecting plate 7 is connected to the rotating rod 402 through a bearing. The connecting plate 7 is fixed to the inner wall of the bell-type furnace 2 and is connected to the end of the rotating rod 402 through the bearing. The connecting plate 7 neither hinders the rotation of the rotating rod 402 nor prevents the rotating rod 402 from shaking when it rotates.

[0024] The filter cover 3 has an overall V-shaped structure. A rotating bearing 8 is provided at the closed end of the filter cover 3, and the rotating rod 402 is located inside the rotating bearing 8. The rotating bearing 8 at the closed end is sleeved on the rotating rod 402, which does not affect the rotation of the rotating rod 402, and can achieve stable support for the filter cover 3 through the bearing connection.

[0025] The protrusions 502 are symmetrically arranged on the filter cover 3, and the actuating blocks 501 are evenly spaced on the rotating rod 403. The actuating blocks 501 and the protrusions 502 cooperate with each other to make the operation of the entire vibration structure 5 more coordinated and efficient. During the rotation of the rotating rod 403, each actuating block 501 will contact the corresponding protrusion 502, so that the filter cover 3 is subjected to uniform and continuous vibration in all directions without dead angles, maximizing the removal of surface impurities, ensuring that the filter cover 3 always maintains good filtration performance, while reducing the wear and tear of various parts of the equipment and extending the overall service life of the device.

[0026] A sliding ramp 9 is provided at the corner of the actuating block 501. When the rotating rod 403 drives the actuating block 501 to rotate, the sliding ramp 9 serves as the first contact point between the actuating block 501 and the protruding block 502. The sliding ramp 9 transforms the original rigid right-angle collision into a gradual ramp contact. This disperses the impact force at the moment of contact, reduces the frictional resistance and wear during contact, and extends the service life of the actuating block 501 and the protruding block 502.

[0027] The role and effect of the embodiments

[0028] In operation, the exhaust fan 1 is started, pumping the exhaust gas to be treated into the bell-shaped furnace 2. The exhaust gas diffuses inside the bell-shaped furnace 2 and flows towards the filter hood 3. As the exhaust gas passes through the V-shaped filter hood 3, impurities are intercepted on the surface of the filter hood, and clean gas is discharged from the top exhaust port 6 after passing through the filter hood 3. Then, the motor 401 is started, driving the rotating rod 402 to rotate, which in turn drives the rotating rod 403 to rotate synchronously. The actuating block 501 on the rotating rod 403 moves with the rotation, and its sliding inclined surface 9 intermittently contacts the protrusion 502 on the filter hood 3. When in contact, the actuating block 501 pushes the protrusion 502, causing the filter hood 3 to vibrate. The vibration causes the impurities attached to the surface of the filter hood 3 to fall off. The dislodged impurities are guided to the bottom by gravity, and are guided through the guide plate 202 into the discharge pipe 201, and finally discharged from the discharge pipe.

[0029] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
