Description
Technical Field
[0001] This utility model relates to the field of acetylene production technology, and in particular to an adsorption filter for a waste gas recovery device. Background Technology
[0002] The adsorption filter screen of the acetylene production waste gas recovery device is a key component used to purify and recover waste gas in the acetylene production process. It usually uses adsorption materials such as activated carbon and molecular sieves. When the waste gas generated by acetylene production passes through the filter screen, these adsorption materials can effectively adsorb impurities such as acetylene, tar, dust and acidic gases in the waste gas due to their rich pore structure, so as to achieve waste gas purification and acetylene recovery.
[0003] However, most filters are fixed with bolts or built-in, requiring special tools for disassembly. This makes the operation difficult and labor-intensive for operators, and can easily lead to improper installation. In addition, the long downtime for installation affects the normal operation of the equipment. Utility Model Content
[0004] The purpose of this utility model is to solve the problems in the existing technology where filters are mostly fixed with bolts or built-in, requiring special tools for disassembly, making it difficult and labor-intensive for operators to disassemble and install filters, and easily leading to improper installation. At the same time, the long downtime for installation affects the normal operation of the equipment. Therefore, this utility model proposes an adsorption filter for a waste gas recovery device.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adsorption filter for a waste gas recovery device, comprising a waste gas recovery box, a filter, and a replacement device. The filter is disposed inside the waste gas recovery box, and the replacement device is disposed on the inner wall of the waste gas recovery box. The replacement device includes a frame, which is fixedly connected to the inner wall of the waste gas recovery box. A frame is inserted into the surface of the frame, and the filter is fixedly connected to the frame. A rod is fixedly connected to the lower surface of the frame. A circular hole is formed on the lower surface of the waste gas recovery box, and the rod is inserted into the circular hole on the lower surface of the waste gas recovery box. An insertion hole is formed on the surface of the rod. A bracket is fixedly connected to the surface of the filter, and a rocker arm is rotatably connected to the surface of the bracket. A connecting rod is fixedly connected to the surface of the rocker arm, and the connecting rod is inserted into a socket on the surface of the insert rod. By setting a replacement device, the filter can be quickly disassembled and assembled without the need for special tools. The old filter can be disassembled simply by rotating the connecting rod and pulling the frame. After inserting the new filter, the connecting rod is automatically locked into the insert rod by the force of the torsion spring to complete the fixation. This simplifies the filter replacement operation, reduces the labor intensity of operators, and reduces the time-consuming replacement problem caused by the complex installation structure. At the same time, it ensures that the filter can be firmly fixed after installation by the engagement of the connecting rod and the insert rod, reducing the possibility of improper installation.
[0006] Preferably, there are two connecting rods, which are symmetrically arranged. By setting the connecting rods, the filter screen and the frame can be detachably fixed. Before replacing the filter screen, the connecting rods can be rotated to disengage it from the insert rod, thereby releasing the fixed constraint on the frame and making it convenient for the operator to pull the frame upward to remove the old filter screen.
[0007] Preferably, a torsion spring is fitted on the surface of the rocker arm. The two ends of the torsion spring are fixedly connected to the bracket and the connecting rod, respectively. By setting the torsion spring, when the new filter screen is inserted into the frame and the insertion rod abuts against the connecting rod, the connecting rod is rotated under force and the torsion spring is simultaneously twisted to accumulate elastic potential energy. When the connecting rod moves to the insertion hole of the insertion rod along with the filter screen, the torsion spring is unrestrained, releases the accumulated elastic potential energy and generates a squeezing force, pushing the connecting rod to automatically insert into the insertion hole of the insertion rod, thereby quickly completing the engagement and fixation of the connecting rod and the insertion rod.
[0008] Preferably, the lower surface of the insertion rod has rounded corners, and the connecting rod is bent. The connecting rod is located at both ends of the insertion rod. By setting the insertion rod, during the installation of the filter screen, when the new filter screen is inserted into the frame, the insertion rod will abut against the connecting rod and cause the connecting rod to rotate under force. When the connecting rod reaches the insertion hole position, the insertion rod can be inserted into the connecting rod after being squeezed by the torsion spring. The engagement of the connecting rod and the insertion rod realizes the stable positioning of the filter screen frame and prevents the filter screen from loosening or shifting during use.
[0009] Preferably, the upper surface of the exhaust gas recovery box is provided with a guiding component, which includes a retainer. The retainer is fixedly connected to the upper surface of the exhaust gas recovery box. The inner wall of the retainer has a through hole, and a rotating rod is rotatably connected to the inner wall of the through hole. A guide wheel is fixedly connected to the surface of the rotating rod. By setting the guiding component, the retainer can be aligned and the guide wheel can be rotated to guide the frame before the frame is inserted into the slot, so that the frame can be accurately and smoothly inserted into the frame. This effectively reduces the problems of jamming and offset when the frame is inserted, reduces the difficulty of insertion, further shortens the filter replacement time, improves the replacement efficiency, reduces repeated adjustment operations caused by poor insertion, and ensures the convenience and stability of the filter replacement process.
[0010] Preferably, the upper surface of the waste gas recovery box is provided with a strip-shaped hole, and the frame is inserted into the strip-shaped hole.
[0011] Preferably, the guide wheels are located at both ends of the strip-shaped hole in the exhaust gas recovery box. The guide wheels are in contact with the frame. By setting the guide wheels, the sliding friction when the frame is inserted is converted into rolling friction, which greatly reduces the frictional resistance between the frame and the frame. This reduces the phenomenon of jamming or sticking when the frame is inserted due to excessive friction. At the same time, with the guiding effect during the rotation process, it is ensured that the frame can always be inserted straight into the frame in the preset direction, preventing the frame from deviating or tilting, thereby helping to achieve accurate and smooth insertion of the frame into the frame.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a replacement device is provided. When the filter needs to be replaced, the connecting rod is rotated, disengaging from the insert rod. Then, the frame is pulled upwards to remove the filter. The new filter is then inserted into the slot and frame until the insert rod and connecting rod abut against each other. The connecting rod rotates under force. When the connecting rod reaches the insertion hole, the torsion spring loses its restraint and generates elastic force to push the connecting rod into the insert rod, completing the replacement. By providing a replacement device, the filter can be quickly disassembled and assembled without the need for special tools. The old filter can be removed simply by rotating the connecting rod and pulling the frame. After inserting the new filter, the torsion spring force causes the connecting rod to automatically engage with the insert rod for fixation. This simplifies the filter replacement operation, reduces the labor intensity of operators, and minimizes the time-consuming replacement caused by complex installation structures. At the same time, it ensures that the filter is securely fixed after installation through the engagement of the connecting rod and the insert rod, reducing the possibility of improper installation.
[0013] In this invention, a guide component is provided to align the frame with the retainer before inserting it into the slot. Guided by the rotation of the guide wheel, the frame is inserted straight into the frame, reducing difficulties in inserting the frame and saving filter replacement time. By providing the guide component, the frame can be aligned with the retainer and guided by the rotation of the guide wheel before insertion into the slot, ensuring accurate and smooth insertion into the frame. This effectively reduces jamming and misalignment during frame insertion, lowers insertion difficulty, further shortens filter replacement time, improves replacement efficiency, reduces repeated adjustments due to poor insertion, and ensures the convenience and stability of the filter replacement process.

[0016] Please see Figures 1-5 This utility model provides a technical solution: an adsorption filter for a waste gas recovery device, including a waste gas recovery box 1, a filter 2 and a replacement device 3. The filter 2 is disposed inside the waste gas recovery box 1, and the replacement device 3 is disposed on the inner wall of the waste gas recovery box 1.
[0017] In this embodiment: the replacement device 3 includes a frame 31, which is fixedly connected to the inner wall of the exhaust gas recovery box 1. A frame 32 is inserted into the surface of the frame 31, and the filter screen 2 is fixedly connected to the frame 32. A rod 33 is fixedly connected to the lower surface of the frame 32. A round hole is opened on the lower surface of the exhaust gas recovery box 1, and the rod 33 is inserted into the round hole on the lower surface of the exhaust gas recovery box 1. An insertion hole is opened on the surface of the rod 33. A bracket 34 is fixedly connected to the lower surface of the exhaust gas recovery box 1. A rocker arm 38 is rotatably connected to the surface of the bracket 34. A connecting rod 35 is fixedly connected to the surface of the rocker arm 38. The connecting rod 35 and... The insertion holes on the surface of the insertion rod 33, along with the replacement device 3, enable quick installation and removal of the filter screen 2. No special tools are needed; simply rotating the connecting rod 35 and pulling the frame 32 removes the old filter screen 2. After inserting the new filter screen 2, the torsion spring 37 automatically engages the connecting rod 35 with the insertion rod 33 to secure it. This simplifies the filter screen 2 replacement process, reduces the workload of operators, and minimizes the time-consuming replacement caused by complex installation structures. Simultaneously, it ensures that the filter screen 2 is securely fixed after installation through the engagement of the connecting rod 35 and the insertion rod 33, reducing the risk of improper installation.
[0018] Specifically, there are two connecting rods 35, which are symmetrically arranged. By setting the connecting rods 35, the filter screen 2 and the frame 31 can be detachably fixed. Before the filter screen 2 is replaced, the connecting rods 35 can be rotated to disengage it from the insert rod 33, thereby releasing the fixed constraint on the frame 32 and making it convenient for the operator to pull the frame 32 upward to remove the old filter screen 2.
[0019] Specifically, a torsion spring 37 is fitted on the surface of the rocker arm 38. The two ends of the torsion spring 37 are fixedly connected to the bracket 34 and the connecting rod 35, respectively. By setting the torsion spring 37, when the new filter screen 2 is inserted into the frame 31 and the insertion rod 33 abuts against the connecting rod 35, the connecting rod 35 is rotated under force and the torsion spring 37 is simultaneously torsioned to accumulate elastic potential energy. When the connecting rod 35 moves to the insertion hole of the insertion rod 33 with the filter screen 2, the torsion spring 37 is unrestrained, releases the accumulated elastic potential energy and generates a squeezing force, pushing the connecting rod 35 to automatically insert into the insertion hole of the insertion rod 33, thereby quickly completing the engagement and fixation of the connecting rod 35 and the insertion rod 33.
[0020] Specifically, the lower surface of the insertion rod 33 is rounded, and the connecting rod 35 is bent. The connecting rod 35 is located at both ends of the insertion rod 33. By setting the insertion rod 33, when the filter screen 2 is installed, during the process of inserting the new filter screen 2 into the frame 31, the insertion rod 33 will abut against the connecting rod 35 and cause the connecting rod 35 to rotate under force. When the connecting rod 35 reaches the insertion hole position, the insertion rod 33 can be inserted into the connecting rod 35 after being squeezed by the torsion spring 37. The engagement between the connecting rod 35 and the insertion rod 33 realizes the stable positioning of the filter screen 2 frame 32, preventing the filter screen 2 from loosening or shifting during use.
[0021] Specifically, the upper surface of the exhaust gas recovery box 1 is provided with a guide component 36, which includes a sleeve 361. The sleeve 361 is fixedly connected to the upper surface of the exhaust gas recovery box 1. The inner wall of the sleeve 361 has a through hole. The inner wall of the through hole of the sleeve 361 is rotatably connected to a rotating rod 362. The surface of the rotating rod 362 is fixedly connected to a guide wheel 363.
[0022] In this embodiment: by setting the guide component 36, the frame 32 can be aligned by the sleeve 361 and guided by the rotation of the guide wheel 363 before it is inserted into the strip hole, so that the frame 32 can be inserted into the frame 31 accurately and smoothly. This effectively reduces the jamming and offset problems when the frame 32 is inserted, reduces the difficulty of insertion, further shortens the filter 2 replacement time, improves replacement efficiency, reduces repeated adjustment operations caused by poor insertion, and ensures the convenience and stability of the filter 2 replacement process.
[0023] Specifically, the upper surface of the exhaust gas recovery box 1 is provided with a strip-shaped hole, and the frame 32 is inserted into the strip-shaped hole.
[0024] Specifically, the guide wheel 363 is located at both ends of the strip hole in the exhaust gas recovery box 1, and the guide wheel 363 is in contact with the frame 32.
[0025] In this embodiment: by setting guide wheels 363, the sliding friction when the frame 32 is inserted is converted into rolling friction, which greatly reduces the frictional resistance between the frame 32 and the frame 31, reduces the jamming and sticking phenomenon caused by excessive friction when the frame 32 is inserted, and at the same time, with the help of the guiding effect during the rotation process, it is ensured that the frame 32 can always be inserted straight into the frame 31 in the preset direction, preventing the frame 32 from deviating or tilting, thereby helping to achieve accurate and smooth insertion of the frame 32 into the frame 31.
[0026] Working principle: By setting the replacement device 3, when the filter screen 2 needs to be replaced, the connecting rod 35 is rotated, and the connecting rod 35 disengages from the insert rod 33. Then, the frame 32 is pulled upwards to remove the filter screen 2. The new filter screen 2 is then inserted into the slot and frame 31 until the insert rod 33 abuts against the connecting rod 35. The connecting rod 35 rotates under force. When the connecting rod 35 reaches the insertion hole, the torsion spring 37 is released and generates elastic force to push the connecting rod 35 into the insert rod 33, completing the replacement. By setting the replacement device 3, the filter screen replacement can be achieved. The quick installation and removal of filter screen 2 does not require special tools. The old filter screen 2 can be removed by simply rotating the connecting rod 35 and pulling the frame 32. After inserting the new filter screen 2, the connecting rod 35 is automatically locked into the insertion rod 33 by the elastic force of the torsion spring 37 to complete the fixation. This simplifies the filter screen 2 replacement operation, reduces the labor intensity of operators, and reduces the time-consuming replacement problem caused by the complex installation structure. At the same time, it ensures that the filter screen 2 can be firmly fixed by the engagement of the connecting rod 35 and the insertion rod 33 after installation, reducing the possibility of improper installation. By setting the guide component 36, the frame 32 is aligned with the sleeve 361 before being inserted into the strip hole. Guided by the rotation of the guide wheel 363, it is inserted straight into the frame 31, reducing the difficulty of inserting the frame 32 and saving the replacement time of the filter 2. By setting the guide component 36, the frame 32 can be aligned with the sleeve 361 and guided by the rotation of the guide wheel 363 before being inserted into the strip hole, so that the frame 32 can be inserted into the frame 31 accurately and smoothly. This effectively reduces the problem of jamming and offset when inserting the frame 32, reduces the difficulty of insertion, further shortens the replacement time of the filter 2, improves the replacement efficiency, reduces repeated adjustment operations caused by poor insertion, and ensures the convenience and stability of the filter 2 replacement process.
