Description

Technical Field

[0001] The present invention relates to the technical field of exhaust pipelines, and particularly relates to a dust reduction exhaust pipeline device for stainless steel environmental protection equipment. Background Art

[0002] When stainless steel environmental protection purifies air, pipelines need to be connected for exhaust work. A pipeline refers to a pipe for transporting working fluids or gases. Compared with a pipe, a pipeline is a reasonably arranged pipe system. Due to the flexibility of pipelines, they are often used in hydraulic systems and other liquid-driven mechanical equipment. A pipeline is a channel for transporting liquids or gases, and can be divided into simple pipelines, parallel pipelines, and branch pipelines according to the layout of its pipes. Parallel pipelines and branch pipelines are collectively called complex pipelines. The flow rate in the main pipeline is equal to the mass flow rate of each parallel pipe segment; the resistance losses of each branch pipeline are equal. At the branch point, regardless of which branch pipe, the total mechanical energy per unit mass of fluid is a certain value.

[0003] In the patent document of a dust reduction exhaust pipeline device for stainless steel environmental protection equipment with the publication number CN210964359U, it includes a transmission pipeline and an exhaust pipeline. The transmission pipeline and the exhaust pipeline are hermetically connected by a flange. A positioning slide rail is provided at the lower end of the exhaust pipeline, and a collection drawer is installed on the positioning slide rail. Connecting slide bars are provided on both the upper surface and the lower surface of the collection drawer. One end of the collection drawer is provided with a pull handle, and the pull handle is located outside the exhaust pipeline. This device plays a role in reducing dust in the exhaust by setting an activated carbon filter. When the exhaust pipeline exhausts air, the gas will pass through the filtration of the activated carbon filter, and small particle dust and debris in the gas will be adsorbed by the activated carbon filter. The gas filtered by the activated carbon filter is discharged from the top of the exhaust pipeline, achieving the purpose of reducing dust in the exhaust, and overcoming the problem that the existing exhaust pipeline device for stainless steel environmental protection equipment cannot effectively perform dust reduction operation on the discharged gas during use, resulting in a large amount of dust or debris still remaining in the discharged gas. However, the above patent document still has the following defects during implementation: After long-term use of this device, a large amount of dust, dust, and other impurity particles will adhere to the surface of the activated carbon filter for filtering gas. This will not only block the pores of the filter, increase the resistance of the gas passing through the filter, reduce the gas passing rate, and thus affect the filtration efficiency, but also the adsorption capacity of the activated carbon filter is limited. A large amount of dust and other impurities adhering to the surface will occupy the adsorption sites of the activated carbon, reducing its adsorption capacity for harmful gases and shortening the effective service life of the activated carbon filter. Therefore, we propose a dust reduction exhaust pipeline device for stainless steel environmental protection equipment to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] Example 1. As Figure 1-7As shown in the figure, a dust-removing and exhaust air pipeline device for a stainless-steel environmental protection equipment includes a first exhaust pipe 1. A connecting pipe 11 is installed at the right end of the first exhaust pipe 1. A second exhaust pipe 12 is installed at the top of the connecting pipe 11. A dust-removing component 2 is arranged inside the second exhaust pipe 12, and a replacement component 3 is arranged inside the second exhaust pipe 12.

[0019] Specifically, in order to achieve the purpose of being able to clean the dust and powder attached to the bottom of the activated carbon filter plate, refer to Figure 2 and Figure 3 , in this embodiment, the dust-removing component 2 includes two air supply pipes 22. An air cylinder 21 is fixedly connected to the inner wall of the second exhaust pipe 12. The outer surfaces of the two air supply pipes 22 close to each other are fixedly connected to the inner wall of the air cylinder 21. A collection drawer 23 is slidably connected to the inner wall of the second exhaust pipe 12. A handle 231 is fixedly connected to the front of the collection drawer 23.

[0020] Furthermore, refer to Figure 3 and Figure 4 , in this embodiment, the outer surfaces of the two air supply pipes 22 are fixedly connected to the inner wall of the second exhaust pipe 12. A connecting cylinder 221 is fixedly connected to the common outer surface of the bottoms of the two air supply pipes 22. The connecting cylinder 221 is located at the bottom of the collection drawer 23.

[0021] Furthermore, refer to Figure 4 , in this embodiment, a rotating shaft 211 is rotatably connected to the inner wall of the top of the air cylinder 21. A fixing frame 212 is fixedly connected to the inner wall of the air cylinder 21. The inner wall of the fixing frame 212 is rotatably connected to the outer surface of the bottom of the rotating shaft 211.

[0022] Furthermore, refer to Figure 4 , in this embodiment, an air wheel 213 is fixedly connected to the outer surface of the rotating shaft 211. A cleaning frame 214 is fixedly connected to the top of the rotating shaft 211. Nylon bristles are installed on the cleaning frame 214.

[0023] During the implementation process, the gas entering the interior of the connecting pipe 11 will be blocked by the collection drawer 23 and can only enter the two air supply pipes 22 through the connecting cylinder 221. The gas entering the two air supply pipes 22 will be transported into the air duct 21. By transporting the gas entering the connecting pipe 11 into the air duct 21 with a smaller diameter, the gas flow rate can be increased. The gas entering the air duct 21 will be discharged back into the connecting pipe 11 through the opening at the top of the air duct 21. When the gas flows, it will blow the wind wheel 213 to rotate. When the wind wheel 213 rotates, it will drive the rotating shaft 211 to rotate. When the rotating shaft 211 rotates, it will drive the cleaning frame 214 to rotate. When the cleaning frame 214 rotates, the nylon bristles at its top can rotate at the bottom of the activated carbon filter plate 321 to clean the dust, dust, and other impurity particles attached to the bottom surface of the activated carbon filter plate 321. Since the nylon bristles are soft and elastic, they can not only effectively clean the dust but also reduce the wear on the filter screen. The cleaned dust, dust, and other impurity particles will fall onto the top of the collection drawer 23 due to gravity. This can not only prevent the pores of the activated carbon filter plate 321 from being blocked, allowing the gas to pass through the filter screen smoothly and ensuring the stability of the filtration efficiency, but also prevent dust and other impurities from occupying the adsorption sites of the activated carbon, enabling the activated carbon to continuously play its adsorption role on harmful gases, thereby extending the effective service life of the activated carbon filter screen.

[0024] Embodiment 2: In this embodiment, a replacement component is provided on the basis of Embodiment 1.

[0025] Specifically, in order to achieve the purpose of quickly and conveniently replacing the activated carbon filter plate, referring to Figure 5 and Figure 6 , in this embodiment, the replacement component 3 includes a support base 31. The outer surface of the support base 31 is fixedly connected to the inner wall of the second exhaust pipe 12. A sliding plate 32 is slidably connected to the inner wall of the support base 31. An activated carbon filter plate 321 is fixedly connected to the inner wall of the sliding plate 32. The bottom of the activated carbon filter plate 321 is in contact with the top of the nylon bristles. A connecting plate 322 is fixedly connected to the right end of the sliding plate 32. The outer surface of the connecting plate 322 is clamped with the inner wall of the second exhaust pipe 12.

[0026] Furthermore, referring to Figure 6 , in this embodiment, two sliding rods 331 are slidably connected to the inner wall of the second exhaust pipe 12. A sealing strip 33 is fixedly connected to the right ends of the two sliding rods 331. Limit blocks 332 are fixedly connected to the left ends of the two sliding rods 331. Spring 333 is sleeved on the outer surfaces of the two sliding rods 331. The left ends of the two springs 333 are fixedly connected to the right ends of the same-side limit blocks 332. The right ends of the two springs 333 are fixedly connected to the inner wall of the second exhaust pipe 12. The right end of the sealing strip 33 is in close contact with the left end of the connecting plate 322.

[0027] Further, referring to Figure 7 In this embodiment, two slide rails 34 are fixedly connected to the outer surface of the second exhaust pipe 12. A limiting frame 341 is slidably connected to the inner walls of the two slide rails 34 in common. The left end of the limiting frame 341 is in close contact with the right end of the connecting plate 322.

[0028] During the implementation process, when it is necessary to replace the activated carbon filter plate 321, first push the limiting frame 341 to slide upward in the inner walls of the two slide rails 34. When the limiting frame 341 slides upward to a certain position, its surface will separate from the outer surface of the connecting plate 322, and the restriction on the connecting plate 322 can be released. After the restriction on the connecting plate 322 is released, the two deformed springs 333 will pull the limiting block 332 to move to the right due to the elastic force. When the limiting block 332 moves, it will drive the corresponding slide rod 331 to slide in the inner wall of the second exhaust pipe 12. When the slide rod 331 slides, it will push the connecting plate 322 to move to the right by a certain position through the sealing strip 33. When the connecting plate 322 moves, it can drive the sliding plate 32 to slide to the right in the inner wall of the support seat 31, so that the staff can directly pull out the sliding plate 32 to replace the activated carbon filter plate 321. After the replacement of the activated carbon filter plate 321 is completed, the sliding plate 32 is reinserted into the inner wall of the support seat 31 through the connecting plate 322 and pushed to the left. When the connecting plate 322 is installed, release the limiting frame 341. The limiting frame 341 will slide downward due to gravity to re-restrict the connecting plate 322. At the same time, when the connecting plate 322 slides, it will push the sealing strip 33 to move to the left. When the sealing strip 33 moves, it will push the two slide rods 331 to slide in the inner wall of the second exhaust pipe 12. When the slide rod 331 slides, it will pull the spring 333 through the limiting block 332 to make it deform again. The deformed spring 333 will push the right end of the sealing strip 33 to closely adhere to the left end of the connecting plate 322 to seal it. When the activated carbon filter plate 321 is adsorbed saturated or damaged, it can be quickly taken out and a new filter plate can be installed, so that the equipment can quickly return to the best operating state, reduce the equipment downtime, ensure the continuous and stable operation of the environmental protection equipment, and moreover, the harmful gas can be prevented from leaking into the external environment to pollute the surrounding environment through the sealing strip 33, protecting the health of the staff.

[0029] The working principle of the present invention is as follows: When the device is in use, the gas will enter the interior of the second exhaust pipe 12 through the first exhaust pipe 1 and the connecting pipe 11. The gas entering the interior of the connecting pipe 11 will be blocked by the collection drawer 23 and can only enter the two air supply pipes 22 through the connecting cylinder 221. The gas entering the two air supply pipes 22 will be transported to the interior of the air cylinder 21. By transporting the gas entering the connecting pipe 11 into the air cylinder 21 with a smaller diameter, the gas flow rate can be increased. The gas entering the interior of the air cylinder 21 will be discharged back into the connecting pipe 11 through the opening at the top of the air cylinder 21. When the gas flows, it will blow the wind wheel 213 to rotate. When the wind wheel 213 rotates, it will drive the rotating shaft 211 to rotate. When the rotating shaft 211 rotates, it will drive the cleaning frame 214 to rotate. When the cleaning frame 214 rotates, the nylon bristles on its top can rotate at the bottom of the activated carbon filter plate 321 to clean the dust, dust, and other impurity particles attached to the bottom surface of the activated carbon filter plate 321. Since the nylon bristles are soft and elastic, they can not only effectively clean the dust but also reduce the wear on the filter screen. The cleaned dust, dust, and other impurity particles will fall onto the top of the collection drawer 23 due to gravity. This can not only prevent the pores of the activated carbon filter plate 321 from being blocked, allowing the gas to pass through the filter screen smoothly and ensuring the stability of the filtration efficiency, but also avoid dust and other impurities occupying the adsorption sites of the activated carbon, enabling the activated carbon to continuously play its adsorption role on harmful gases, thereby prolonging the effective service life of the activated carbon filter screen.

[0030] When it is necessary to replace the activated carbon filter plate 321, first push the limit frame 341 to slide upward in the inner walls of the two slide rails 34. When the limit frame 341 slides upward to a certain position, its surface will be separated from the outer surface of the connecting plate 322, and the restriction on the connecting plate 322 can be released. After the restriction on the connecting plate 322 is released, the two deformed springs 333 will pull the limit block 332 to move to the right due to the elastic force. When the limit block 332 moves, it will drive the corresponding slide rod 331 to slide in the inner wall of the second exhaust pipe 12. When the slide rod 331 slides, it will push the connecting plate 322 to move to the right by a certain position through the sealing strip 33. When the connecting plate 322 moves, it can drive the sliding plate 32 to slide to the right in the inner wall of the support seat 31, so that the staff can directly pull out the sliding plate 32 to replace the activated carbon filter plate 321. After the activated carbon filter plate 321 is replaced, the sliding plate 32 is reinserted into the inner wall of the support seat 31 through the connecting plate 322 and pushed to the left. When the connecting plate 322 is installed, release the limit frame 341. The limit frame 341 will slide downward due to gravity to re-restrict the connecting plate 322. At the same time, when the connecting plate 322 slides, it will push the sealing strip 33 to move to the left. When the sealing strip 33 moves, it will push the two slide rods 331 to slide in the inner wall of the second exhaust pipe 12. When the slide rod 331 slides, it will pull the spring 333 through the limit block 332 to make it deform again. The deformed spring 333 will push the right end of the sealing strip 33 to closely adhere to the left end of the connecting plate 322 to seal it. When the activated carbon filter plate 321 is saturated or damaged by adsorption, it can be quickly taken out and a new filter plate can be installed, so that the equipment can quickly return to the best operating state, reduce the equipment downtime, ensure the continuous and stable operation of the environmental protection equipment, and moreover, the sealing strip 33 can prevent harmful gases from leaking into the external environment and polluting the surrounding environment, protecting the health of the staff.
