Description

Technical Field

[0001] This utility model relates to the field of waste gas filtration technology, and in particular to a waste gas filtration device for a target furnace. Background Technology

[0002] When metal targets are forged at high temperatures in a vacuum melting furnace, waste gas is generated. Commercially available filtration devices cannot replace the filter elements, or cannot replace the filter elements in a timely manner according to their consumption, thus affecting the filtration effect, resulting in the waste gas not being purified, ultimately polluting the air and damaging the environment.

[0003] The prior art CN218358130U discloses a waste gas filtration device for a vacuum melting furnace for target materials, including a base, a filter cylinder on the base, an L-shaped air inlet pipe on the filter cylinder, one end of the L-shaped air inlet pipe connected to the exhaust port of the vacuum melting furnace, a check valve on the L-shaped air inlet pipe, and the other end of the L-shaped air inlet pipe extending into the interior of the filter cylinder. A conical tube is connected to the filter cylinder, and an L-shaped exhaust pipe is connected to the conical tube. The filter cylinder has a first removable filter box and a second removable filter box arranged sequentially on its body. The first and second removable filter boxes have the same structure, with a hollowed-out mesh bottom and an adsorption layer inside. The adsorption layer includes an activated carbon layer, and a white nano-sponge layer is placed above the activated carbon layer. By filtering the waste gas through the double-layer activated carbon and double-layer nano-sponge, the waste gas generated by the vacuum melting furnace can be effectively purified. The operator can observe whether the nano-sponge changes color through a glass viewing window so as to replace the activated carbon and nano-sponge in time to ensure the filtration effect.

[0004] However, when using the above method, the filter box is designed to be pulled out of the filter cylinder, which creates a gap between the filter box and the filter cylinder, resulting in poor sealing and affecting the filtration effect. Utility Model Content

[0005] The purpose of this utility model is to provide a waste gas filtration device for target material furnaces, which can improve the sealing between the filter box and the filter cylinder when the device is used for filtration, thereby improving the filtration effect.

[0006] To achieve the above objectives, this utility model provides a waste gas filtration device for a target furnace, comprising a base, a filter cylinder, a filter box, and a conical tube. The filter cylinder is fixedly connected to the base and located on one side of the base. The filter box is slidably disposed on the filter cylinder. The conical tube is fixedly disposed at the top of the filter cylinder. It also includes an airtight component. The airtight assembly includes a placement ring, a sliding ring, a rubber pad, and a fixing member. The placement ring is fixedly connected to the filter cartridge and located on one side of the filter cartridge. The sliding ring is slidably connected to the filter cartridge and located on one side of the filter cartridge. The rubber pad is fixedly connected to the sliding ring and located on one side of the sliding ring. The sliding ring is kept stable on the filter cartridge by the fixing member.

[0007] The fixing component includes a positioning ring and an abutment ring. The positioning ring is fixedly connected to the filter cylinder and is located on one side of the filter cylinder. The abutment ring is fixedly connected to the sliding ring and is located on the side of the sliding ring closer to the positioning ring.

[0008] The abutment ring is provided with a plug rod, which is fixedly connected to the abutment ring and located on the side of the abutment ring closer to the positioning ring.

[0009] The positioning ring has a through hole that penetrates the positioning ring, and the diameter of the through hole is adapted to the diameter of the plug rod.

[0010] The plug rod is provided with a locking nut, which is threadedly connected to the plug rod and abuts against the positioning ring.

[0011] This utility model discloses a waste gas filtration device for a target material furnace, comprising a base, a filter cylinder, a filter box, a conical tube, and an airtight assembly. The airtight assembly includes a placement ring, a sliding ring, a rubber pad, and a fixing component. During use, the sliding ring is moved, causing it to move the rubber pad to the connection point between the filter cylinder and the filter box. The rubber pad then wraps and seals the connection point, which is then fixed by the fixing component. This improves the sealing performance of the device during filtration, thereby enhancing the filtration effect. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The first embodiment of this application is: Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of the exhaust gas filtration device for target material furnaces. Figure 2 This is a structural diagram of an airtight component. Figure 3 This is a schematic diagram of the sliding ring's movement. This utility model provides a waste gas filtration device for a target material furnace: it includes a base 101, a filter cylinder 102, a filter box 103, a conical tube 104, and an airtight assembly. The airtight assembly includes a placement ring 105, a sliding ring 106, a rubber pad 107, and a fixing component. The fixing component includes a positioning ring 108 and an abutment ring 109. An insertion rod 110 is provided on the abutment ring 109. The positioning ring 108 has a through hole 111, and a locking nut 112 is provided on the insertion rod 110. The aforementioned solution solves the problem that during device use, the filter box is pulled out of the filter cylinder, resulting in a gap between the filter box and the filter cylinder, leading to poor sealing and affecting the filtration effect. It is understood that the aforementioned solution can improve the sealing between the filter box and the filter cylinder during device use, thereby improving the filtration effect. It can also be used to further improve the airtightness between the filter cylinder and the filter box.

[0019] In this specific embodiment, the filter cylinder 102 is fixedly connected to the base 101 and located on one side of the base 101. The filter box 103 is slidably disposed on the filter cylinder 102. The tapered tube 104 is fixedly disposed on the top end of the filter cylinder 102. The filter cylinder 102 is disposed on the base 101. The cross-section of the filter cylinder 102 is elliptical. The top end of the filter cylinder 102 is connected to an exhaust pipe through the tapered tube 104. The filter box 103 disposed on the filter cylinder 102 is retractable. An adsorption layer is disposed inside the filter box 103 for filtering exhaust gas. An air inlet pipe is disposed on one side of the bottom of the outer surface of the filter cylinder 102 for the entry of exhaust gas. The gas discharged after filtration has no irritating odor and will not cause pollution to the environment. All of the above are existing technologies.

[0020] The placement ring 105 is fixedly connected to the filter cylinder 102 and located on one side of the filter cylinder 102. The sliding ring 106 is slidably connected to the filter cylinder 102 and located on one side of the filter cylinder 102. The rubber pad 107 is fixedly connected to the sliding ring 106 and located on one side of the sliding ring 106. The sliding ring 106 is kept stable on the filter cylinder 102 by the fixing member. The placement ring 105 is welded to the outer surface of the filter cylinder 102. The placement ring 105 is located below the filter box 103. The sliding ring 106 is placed on the placement ring 105. The inner surface of the sliding ring 106 is in close contact with the filter cylinder 102. The size of the placement ring 105 is larger than that of the sliding ring 106. The placement ring 105 is used to support the sliding ring 106. The sliding ring 106 is provided with a rubber pad 107, which is made of soft rubber. During the use of the device, the sliding ring 106 is moved, causing the sliding ring 106 to move the rubber pad 107 to the connection between the filter cylinder 102 and the filter box 103. This allows the rubber pad 107 to wrap and seal the connection between the filter cylinder 102 and the filter box 103, and then fix it by the fixing member, thereby improving the sealing of the device during filtration and thus improving the filtration effect.

[0021] Secondly, the positioning ring 108 is fixedly connected to the filter cylinder 102 and located on one side of the filter cylinder 102; the abutment ring 109 is fixedly connected to the sliding ring 106 and located on the side of the sliding ring 106 near the positioning ring 108. The positioning ring 108 has a semi-circular structure and is welded to the rear side of the outer surface of the filter cylinder 102. The positioning ring 108 is located on the plane of the filter box 103 and is located above the placement ring 105. The abutment ring 109 is welded to... On the upper surface of the sliding ring 106, the abutment ring 109, in conjunction with the sliding ring 106, surrounds the rubber pad 107, thereby improving the tightness of the rubber pad 107 when in contact with the filter cartridge 102. When the sliding ring 106 moves, it drives the abutment ring 109 to move towards the positioning ring 108, so that the positioning ring 108 can abut against the abutment ring 109. At this time, the rubber pad 107 wraps the connection between the filter box 103 and the filter cartridge 102, playing a double sealing role.

[0022] Meanwhile, the insertion rod 110 is fixedly connected to the abutment ring 109 and is located on the side of the abutment ring 109 closer to the positioning ring 108; the through hole 111 penetrates the positioning ring 108, and the diameter of the through hole 111 is adapted to the diameter of the insertion rod 110; the locking nut 112 is threadedly connected to the insertion rod 110 and abuts against the positioning ring 108; the positioning ring 108 has through holes 111 on both its left and right ends; the insertion rod 110 is symmetrically welded to the upper surface of the abutment ring 109; the position of the insertion rod 110 corresponds to the position of the through hole 111, so that when the sliding ring 106 moves on the filter cylinder 102, it drives the abutment ring 110 to abut against the positioning ring 108. Ring 109 moves toward positioning ring 108, causing the insertion rod 110 on the abutment ring 109 to insert into the through hole 111 of positioning ring 108. Then, the locking nut 112 is screwed into the top of the insertion rod 110 until the locking nut 112 abuts against positioning ring 108, thereby locking and fixing positioning ring 108 and abutment ring 109. This ensures that positioning ring 108 remains stable after abutting against positioning ring 109, and the rubber pad 107 inside positioning ring 108 wraps around the connection between filter cartridge 102 and filter box 103, further improving airtightness and thus improving filtration effect.

[0023] When using the target material furnace exhaust gas filtration device of this embodiment, during the use of the device, the sliding ring 106 is moved, causing the sliding ring 106 to drive the rubber pad 107 to move to the connection between the filter cylinder 102 and the filter box 103, so that the rubber pad 107 wraps and seals the connection between the filter cylinder 102 and the filter box 103, and then fixes it by the fixing component, thereby improving the sealing of the device during filtration and thus improving the filtration effect.

[0024] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
