Description

Technical Field

[0001] This invention belongs to the field of purification device technology, specifically a purification device for welded pipe processing. Background Technology

[0002] During the processing of welded pipes, such as rolling, welding, grinding, and cutting, a large amount of pollutants such as high-temperature welding fumes, metal dust, and welding slag particles are generated. By installing purification devices in the processing environment, welding fumes, dust, and welding slag can be filtered and purified in a timely and efficient manner to ensure that the production environment meets standards, equipment operates stably, and the production line operates continuously.

[0003] When using existing purification devices for welded pipe processing, the device is usually placed near the welded pipe processing station. The device is equipped with a filter structure. After the fan is started, a negative pressure is generated, which draws the welding fumes, welding slag and dust generated during the welded pipe processing into the device. The airflow passes through the filter structure, and the welding slag and dust are intercepted on the outside of the filter structure. The purified gas is then discharged from the device. The existing purification devices for welded pipe processing mentioned above mostly use a fixed installation method for their filter structure, with the filter hole positions remaining unchanged. The flue gas always passes through the same set of filter holes for filtration. During long-term continuous operation, a large amount of welding slag, dust and other impurities generated during welded pipe processing will continuously adhere to and accumulate inside the filter holes. The filter holes become blocked due to the accumulation of welding slag. After the blockage, the air passage area is reduced, making it difficult for the device to effectively absorb and purify the welding slag and flue gas generated during processing, thus causing a decrease in purification efficiency.

[0004] Therefore, the present invention provides a purification device for welded pipe processing. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology and solve the problem mentioned in the background technology that the filter hole position remains unchanged, causing the filter hole to become blocked due to the accumulation of welding slag, thereby reducing the purification efficiency.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a purification device for welded pipe processing, comprising a main body, a filter ring rotatably connected inside the main body, a rotating rod provided on the inner side of the filter ring, the rotating rod being rotatably connected to the inside of the main body, a movable rod being slidably and rotatably connected inside the rotating rod, a first elastic telescopic rod being fixedly connected to the surface of the rotating rod, a movable frame being fixedly connected to the telescopic end of the first elastic telescopic rod, a plurality of fixed rods being fixedly connected to the lower surface of the movable frame, a conical head being slidably connected inside the fixed rod, and the size and number of filter holes on the fixed rod and the filter ring corresponding to each other.

[0007] Preferably, an air inlet is provided on one side of the main body, a partition is provided inside the main body, a fan is provided on the bottom side of the partition, the fan is fixedly connected to the inside of the main body, an exhaust port is provided on one side of the fan, an air inlet pipe is fixedly connected to one side of the main body, an exhaust hood is fixedly connected to one end of the air inlet pipe, and the exhaust hood is fixedly connected to the side wall of the main body.

[0008] Preferably, a storage box is fixedly connected to the upper surface of the partition, and baffles are fixedly connected to both the upper surface of the partition and the interior of the body, with one side of each baffle being in contact with the surface of the filter ring.

[0009] Preferably, a motor is fixedly connected to one side of the main body, a dial is fixedly connected to the output end of the motor, and a driven disc is fixedly connected to one end of the rotating rod.

[0010] Preferably, a limiting post is provided on the inner side of the rotating rod, one end of the limiting post is fixedly connected to one side of the body, the other end of the body is fixedly connected to a support plate, the support plate is fixedly connected to one side of the exhaust hood, and a protruding ring is fixedly connected to the surface of the limiting post.

[0011] Preferably, the surface of the movable rod is provided with a first spiral groove, and a first limiting rod is fixedly connected inside the rotating rod, with one end of the first limiting rod slidably connected to the inside of the first spiral groove.

[0012] Preferably, a movable plate is fixedly connected to one end of the cone, a second limiting rod is fixedly connected to the upper surface of the movable plate, a second spiral groove is provided on the surface of the movable rod, and the inner side of the second spiral groove and one end of the second limiting rod are slidably connected.

[0013] Preferably, a second spring telescopic rod is fixedly connected inside the movable frame, and the telescopic end of the second spring telescopic rod is fixedly connected to the upper surface of the movable plate.

[0014] Preferably, a brush ring is fixedly connected inside the fixing rod, and the inner side of the brush ring is provided with brush bristles, the size of which matches the size of the cone head.

[0015] Preferably, one end of the movable rod is rotatably connected to a ball bearing, and a limiting ring is fixedly connected to the surface of the first limiting rod, with the limiting ring and the surface of the movable frame being in contact.

[0016] The beneficial effects of this invention are as follows: 1. The purification device for welded pipe processing described in this invention comprises a dial, a driven plate, and a fixed rod. When the motor drives the dial to rotate, the dial and driven plate work together to intermittently rotate the rotating rod. The rotating rod rotates and drives the moving rod to rotate synchronously. The moving rod drives the moving frame to rotate synchronously. The moving frame drives the fixed rod to rotate synchronously. The fixed rod is located in the filter hole inside the filter ring, which drives the filter ring to rotate intermittently. The rotation of the filter ring drives the filter hole to be replaced. When the replaced filter hole rotates to the air inlet, the moving frame slides out of the filter hole and opens the filter hole to allow air intake. This device can intermittently replace the filter hole on the filter ring, allowing the filter hole to work in turn. This avoids the problem of rapid clogging caused by continuous filtration, which makes it difficult to absorb and purify the welding slag generated during processing. Therefore, frequent shutdowns for cleaning are required, resulting in a decrease in filtration efficiency.

[0017] 2. The purification device for welded pipe processing described in this invention, by setting a limiting post and a convex ring, when the moving rod rotates from the surface of the limiting post to the surface of the convex ring, the moving rod is squeezed by the convex ring. The moving rod drives the fixed rod below the moving frame to move towards the inside of the filter hole. The fixed rod drives the cone head to move inside the filter hole. The cone head can break up the welding slag blocking the filter hole and, together with the fixed rod, push the impurities in the filter hole into the collection box for centralized collection. This device can realize automatic cleaning of the filter hole, breaking up welding slag and centralized collection, without manual intervention and machine shutdown. It avoids the problem in the prior art where, after long-term use, impurities generated from welded pipe processing continuously accumulate in the filter hole and block it, resulting in poor air circulation, reduced purification efficiency, and difficulty in effectively filtering welding slag generated from welded pipe processing.

[0018] 3. The purification device for welded pipe processing described in this invention, by setting a first limiting rod and a second limiting rod, when the fixed rod drives the cone head away from the filter hole and opens the filter hole for air intake, the moving rod resets and one end is in contact with the surface of the limiting post. The first limiting rod drives the moving rod to rotate, and the rotation of the moving rod drives the second spiral groove to rotate synchronously, so that the second limiting rod drives the moving plate to move upward. The moving plate drives the cone head to be stored inside the fixed rod. At the same time, the bristles on the brush ring inside the fixed rod can clean the surface of the cone head. Then the cone head is pushed to the inside of the bristles, and the bristles block impurities from entering the fixed ring. This device can store the cone head, clean its surface, and provide dust protection inside the fixed rod. It avoids the cone head being exposed to the outside when not being cleaned, and its surface is prone to the adhesion of welding slag, dust and other impurities, which cannot be cleaned in time. This leads to the accumulation and clumping of impurities on the surface of the cone head, and the inability to effectively break up the welding slag in the filter hole during subsequent cleaning, thus causing a decrease in the cleaning effect inside the filter hole.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 8 As shown in the embodiment of the present invention, a purification device for welded pipe processing includes a body 1. A filter ring 5 is rotatably connected inside the body 1. A rotating rod 4 is provided on the inner side of the filter ring 5. The rotating rod 4 is rotatably connected to the inside of the body 1. A movable rod 41 is slidably and rotatably connected inside the rotating rod 4. A first elastic telescopic rod is fixedly connected to the surface of the rotating rod 4. A movable frame 42 is fixedly connected to the telescopic end of the first elastic telescopic rod. A plurality of fixed rods 421 are fixedly connected to the lower surface of the movable frame 42. A cone head 442 is slidably connected inside the fixed rod 421. The size and number of filter holes on the fixed rod 421 and the filter ring 5 are corresponding.

[0023] like Figure 4As shown, an air inlet 11 is provided on one side of the main body 1, a partition 16 is provided inside the main body 1, a fan 15 is provided on the bottom side of the partition 16, the fan 15 is fixedly connected to the inside of the main body 1, an exhaust port 12 is provided on one side of the fan 15, an air inlet pipe 14 is fixedly connected to one side of the main body 1, an exhaust hood 13 is fixedly connected to one end of the air inlet pipe 14, the exhaust hood 13 is fixedly connected to the side wall of the main body 1, an activated carbon layer is installed at the exhaust port 12, and the flue gas passes through the activated carbon layer and is discharged from the exhaust port 12, thus realizing the absorption and purification of odorous gases.

[0024] like Figure 2 As shown, a motor 2 is fixedly connected to one side of the main body 1, a dial 21 is fixedly connected to the output end of the motor 2, and a driven plate 22 is fixedly connected to one end of the rotating rod 4. Both the dial 21 and the driven plate 22 are existing intermittent motion mechanisms.

[0025] Specifically, in existing purification devices for welded pipe processing, the filter structure is mostly fixed, with the filter hole position remaining unchanged. The flue gas always passes through the same set of filter holes for filtration. During long-term continuous operation, a large amount of welding slag, dust and other impurities generated during welded pipe processing will continuously adhere to and accumulate inside the filter holes. The filter holes become blocked due to the accumulation of welding slag. After the blockage, the air passage area is reduced, making it difficult for the device to effectively absorb and purify the welding slag and flue gas generated during processing, thus causing a decrease in purification efficiency. To avoid the above problems, this device is used as follows: When the device is needed, the blower 15 is turned on, the blower 15 generates negative pressure airflow, and the welding slag and fumes generated by the welding pipe processing enter through the air inlet 11. The fumes pass through the filter holes on the filter ring 5, the welding slag is blocked by the filter ring 5, and enters the interior of the main body 1 through the exhaust hood 13 and the exhaust pipe. Then the fumes are discharged through the exhaust port 12 of the activated carbon layer. When the fan 15 is turned on, the motor 2 is also turned on and runs synchronously. The motor 2 drives the dial 21 to rotate, and the dial 21 drives the lever on its surface to move. When the lever moves to the slot on the driven plate 22, the dial 21 contacts the limit of the driven plate 22, so that the lever slides in the slot and drives the dial 21 to rotate. The dial 21 drives the rotating rod 4 to rotate synchronously, so that the rotating rod 4 can be rotated intermittently. The rotating rod 4 drives the moving frame 42 on its surface to rotate synchronously. The moving frame 42 drives the fixed rod 421 to rotate synchronously. The fixed rod 421 is in the filter hole of the filter ring 5. Therefore, the fixed rod 421 drives the filter ring 5 to rotate synchronously, so that the filter hole can be replaced. When the replaced filter hole moves to the air inlet 11, the fixed rod 421 moves away from the filter hole and opens the filter hole, so that the subsequent air intake operation can be realized. This device can intermittently replace the filter holes on the filter ring 5, allowing the filter holes to work in turn. This avoids the problem of rapid clogging caused by continuous filtration, which would make it difficult to absorb and purify the welding slag generated during processing. As a result, it would require frequent shutdowns for cleaning, thus causing a decrease in filtration efficiency.

[0026] like Figure 3 As shown, a storage box 18 is fixedly connected to the upper surface of the partition 16, and baffles 17 are fixedly connected to both the upper surface of the partition 16 and the interior of the body 1. One side of each baffle 17 is in contact with the surface of the filter ring 5.

[0027] like Figure 5 and Figure 6 As shown, a limiting post 3 is provided on the inner side of the rotating rod 4. One end of the limiting post 3 is fixedly connected to one side of the body 1, and a support plate is fixedly connected to the other end of the body 1. The support plate is fixedly connected to one side of the exhaust hood 13, and a protruding ring 31 is fixedly connected to the surface of the limiting post 3.

[0028] Specifically, during use, the weld slag of the filter ring 5 is inconsistent in size, causing some weld slag to accumulate and block the inside of the filter holes, resulting in poor airflow through the filter holes. It is also necessary to stop the machine to clean and maintain the filter holes of the filter ring 5, thus causing the problem of low purification efficiency.

[0029] To solve the above problems, this device is used as follows: When the rotating rod 4 rotates, the rotating rod 4 drives the moving rod 41 to rotate synchronously, so that when the ball at one end of the moving rod 41 rotates from the surface of the limiting post 3 to the surface of the convex ring 31, the moving rod 41 is squeezed by the convex ring 31. The moving rod 41 drives the moving frame 42 to slide synchronously. The moving frame 42 stretches the telescopic end of the first spring telescopic rod 45. At the same time, the moving frame 42 drives the fixed rod 421 and the cone 442 to slide into the filter hole. The cone 442 can break the impurities in the filter hole, and the fixed rod 421 can push the impurities out of the filter hole. The impurities are pushed out to the collection box 18 for collection.

[0030] This device can automatically clear filter holes, crush welding slag, and collect it centrally without manual intervention or machine downtime. It avoids the problem in existing technologies where impurities generated during welded pipe processing accumulate in the filter holes after long-term use, clogging them, causing poor airflow, reduced purification efficiency, and difficulty in effectively filtering welding slag generated during welded pipe processing.

[0031] Example 2: Figures 5 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the surface of the moving rod 41 is provided with a first spiral groove 411, the inside of the rotating rod 4 is fixedly connected with a first limiting rod 43, and one end of the first limiting rod 43 is slidably connected to the inside of the first spiral groove 411.

[0032] like Figure 7 and Figure 8 As shown, a movable plate 44 is fixedly connected to one end of the cone head 442, and a second limiting rod 441 is fixedly connected to the upper surface of the movable plate 44. A second spiral groove 413 is provided on the surface of the movable rod 41. The inner side of the second spiral groove 413 is slidably connected to one end of the second limiting rod 441. A second spring telescopic rod 443 is fixedly connected inside the movable frame 42, and the telescopic end of the second spring telescopic rod 443 is fixedly connected to the upper surface of the movable plate 44.

[0033] like Figure 7 As shown, a brush ring 422 is fixedly connected inside the fixing rod 421. The inner side of the brush ring 422 is provided with brush bristles, and the size of the brush bristles matches the size of the cone head 442.

[0034] like Figure 7 As shown, one end of the moving rod 41 is rotatably connected to a ball bearing, and a limiting ring 412 is fixedly connected to the surface of the first limiting rod 43. The limiting ring 412 and the surface of the moving frame 42 are in contact. When the moving rod 41 moves, the moving rod 41 drives the limiting ring 412 to move synchronously, and the limiting rod can push the moving frame 42 to move synchronously. When the limiting frame rises, the limiting frame drives the limiting rod to move upward synchronously.

[0035] Specifically, when the aforementioned cone 442 is used, it is exposed and exposed to the welding fumes and dust generated during pipe welding for a long time. When the cone 442 is exposed for a long time without being cleaned, the welding slag, dust and other impurities generated during pipe welding will continuously adhere to the surface of the cone 442 and cannot be cleaned in time. Long-term accumulation will cause the impurities to accumulate and clump, making the surface of the cone 442 rough and reducing its sharpness. After the impurities accumulate on the surface of the cone 442, when the filter hole is cleaned later, the clumped impurities will affect the contact between the cone 442 and the welding slag in the filter hole, causing the cone 442 to be unable to effectively break up the clumped welding slag, thus reducing the cleaning effect and causing a decrease in purification efficiency. To avoid the above problems, this device operates as follows: When the moving rod 41 moves from the surface of the convex ring 31 to the surface of the limiting rod, the first limiting rod 43 slides in the first spiral groove 411 on the surface of the moving rod 41, causing the moving rod 41 to rotate. The moving rod 41 drives the second spiral groove 413 to rotate, causing the second limiting rod 441 to slide in the second spiral groove 413. The second spring telescopic rod 443 drives the moving plate 44 to rise inside the moving frame 42, causing the moving frame 42 to drive the cone head 442 to slide inside the fixed rod 421. During the sliding process, the cone head 442 contacts the brush ring 422, and the bristles on the brush ring 422 clean the impurities on the surface of the cone head 442. Then, the cone head 442 moves to one side of the brush ring 422, and the bristles seal one end of the fixed rod 421, making it difficult for impurities to enter. When the moving rod 41 moves from the surface of the limiting rod to the surface of the convex ring 31, the cone head 442 slides out of the fixed rod 421 and cleans the filter holes.

[0036] This device can store the cone head 442, clean its surface, and provide dust protection inside the fixing rod 421. This prevents the cone head 442 from being exposed when not being cleaned, as its surface is prone to accumulating welding slag, dust, and other impurities that cannot be cleaned in time. This leads to the accumulation and clumping of impurities on the surface of the cone head 442, making it impossible to effectively break up the welding slag inside the filter hole during subsequent cleaning, thus causing a decrease in the cleaning effect inside the filter hole.

[0037] Working principle: When the device is needed, the blower 15 is turned on, generating a negative pressure airflow. Welding slag and fumes from pipe welding enter through the inlet 11. The fumes pass through the filter holes on the filter ring 5, while the welding slag is blocked by the filter ring 5. The fumes then enter the interior of the main body 1 through the exhaust hood 13 and the exhaust pipe. Subsequently, the fumes are discharged through the exhaust port 12 of the activated carbon layer. Simultaneously, the motor 2 is turned on and runs synchronously. The motor 2 drives the dial 21 to rotate, which in turn drives the lever on its surface. When the lever moves into the slot on the driven plate 22, the dial 21... The contact limit on the driven disk 22 causes the lever to slide in the slot and drive the dial 21 to rotate. The dial 21 drives the rotating rod 4 to rotate synchronously, thus achieving intermittent rotation of the rotating rod 4. The rotating rod 4 drives the moving frame 42 on its surface to rotate synchronously. The moving frame 42 drives the fixed rod 421 to rotate synchronously. The fixed rod 421 is located in the filter hole of the filter ring 5. Therefore, the fixed rod 421 drives the filter ring 5 to rotate synchronously, so that the filter hole can be replaced. When the replaced filter hole moves to the air inlet 11, the fixed rod 421 moves away from the filter hole and opens the filter hole, thus realizing the subsequent air intake operation. When the rotating rod 4 rotates, it drives the moving rod 41 to rotate synchronously. When the ball at one end of the moving rod 41 rotates from the surface of the limiting rod to the surface of the convex ring 31, the moving rod 41 is squeezed by the convex ring 31. The moving rod 41 drives the moving frame 42 to slide synchronously. The moving frame 42 stretches the telescopic end of the first spring telescopic rod 45. At the same time, the moving frame 42 drives the fixed rod 421 and the cone 442 to slide into the filter hole. The cone 442 can break the impurities in the filter hole, and the fixed rod 421 can push the impurities out of the filter hole. The impurities are pushed out to the collection box 18 for collection. When the moving rod 41 moves from the surface of the convex ring 31 to the surface of the limiting post 3, the first limiting rod 43 slides in the first spiral groove 411 on the surface of the moving rod 41, causing the moving rod 41 to rotate. The moving rod 41 drives the second spiral groove 413 to rotate, causing the second limiting rod 441 to slide in the second spiral groove 413. The second spring telescopic rod 443 drives the moving plate 44 to rise inside the moving frame 42, causing the moving frame 42 to drive the cone head 442 to slide inside the fixed rod 421. During the sliding process, the cone head 442 contacts the brush ring 422. The bristles on the brush ring 422 clean the impurities on the surface of the cone head 442. Then the cone head 442 moves to one side of the brush ring 422, and the bristles seal one end of the fixed rod 421, making it difficult for impurities to enter. When the moving rod 41 moves from the surface of the limiting post 3 to the surface of the convex ring 31, the cone head 442 slides out from the fixed rod 421 and cleans the filter hole.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
