Description

Technical Field

[0001] This utility model relates to the field of organic waste gas treatment technology, and in particular to a catalyst carrier device for organic waste gas treatment. Background Technology

[0002] In the treatment of organic waste gas, the catalyst carrier device is the core component of the catalytic oxidation system, and the catalyst it carries directly affects the waste gas treatment efficiency. Currently, common catalyst carrier devices typically employ multiple carrier bodies arranged side by side within a housing chamber. Waste gas enters through an inlet pipe, flows over the catalyst layer on the surface of the carrier body for reaction, and is then discharged through an outlet pipe.

[0003] In the prior art, such as the utility model patent with publication number CN216024124U, a catalyst carrier device for treating organic waste gas is disclosed. This device enables the rapid installation and disassembly of the carrier body through a fixing mechanism, and avoids carrier loosening caused by accidental contact through a protective mechanism.

[0004] However, this device still has the following shortcomings in practical use: It uses a spring-driven locking mechanism, relying solely on spring force to maintain the locked state. During long-term operation, the locking mechanism is prone to loosening due to airflow impact and system vibration, leading to instability in the carrier body's position and affecting sealing performance and reaction efficiency. Furthermore, each carrier body requires an individual pressing of the unlocking mechanism for disassembly. When multiple carriers need to be replaced, the operation is cumbersome and time-consuming, increasing maintenance time and labor costs. Therefore, a catalyst carrier device for organic waste gas treatment is needed to meet these requirements. Summary of the Invention

[0005] The purpose of this invention is to provide a catalyst carrier device for treating organic waste gas, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a catalyst carrier device for treating organic waste gas, comprising a housing, an inlet pipe, an outlet pipe, a chamber, a mounting groove, a carrier body, and a frame. The carrier body is movably installed within the frame, which is inserted into the mounting groove. Two pins, T-shaped shafts, are provided on one side of the frame. A protective cover is provided outside the housing, and several bidirectional screws are rotatably connected inside the protective cover. Each bidirectional screw is driven by two symmetrically moving blocks, and a wedge-shaped block with a straight groove is provided on the side of the two moving blocks that are close to each other. The web shaft of the pin is engaged in the straight groove. A rotating shaft is rotatably connected inside the protective cover, and several first helical gears are connected to the rotating shaft. A second helical gear is connected to one end of each bidirectional screw, and each second helical gear meshes with a corresponding first helical gear.

[0007] Preferably, sealing gaskets are provided on both sides of the mounting groove, and the frame is located between the two sealing gaskets to ensure the airtightness of the carrier after installation and prevent exhaust gas leakage.

[0008] Preferably, a socket is provided on one side of the mounting groove. The diameter of the socket is the same as the outer diameter of the wing shaft of the pin. A sealing ring is added inside the socket to further improve the sealing effect.

[0009] Preferably, the two moving blocks on the same bidirectional screw are respectively provided with threaded holes that are adapted to the positive thread section and the negative thread section of the bidirectional screw, so as to ensure that the two moving blocks can move synchronously towards or in opposite directions.

[0010] Preferably, a guide rod is provided between the side walls of the protective cover, and the two moving blocks on the same bidirectional screw are slidably connected to the same guide rod to ensure the stability of the moving blocks and prevent rotation.

[0011] Preferably, the protective cover is movably connected to a cover body, which facilitates the maintenance and repair of the internal mechanism.

[0012] The beneficial effects of this utility model are: This invention employs a mechanical locking method using a T-shaped pin and a wedge-shaped block with a straight groove, combined with a wedge-shaped locking mechanism driven by a bidirectional screw, to form a stable mechanical lock that effectively resists airflow impact and equipment vibration, preventing the carrier from loosening.

[0013] In this invention, a single rotating shaft drives multiple helical gear sets, which can simultaneously control the rotation of all bidirectional screws, enabling the synchronous locking or unlocking of multiple carrier frames. This greatly shortens the disassembly and assembly time and improves maintenance efficiency. All operating mechanisms are centrally located inside the protective cover outside the housing. Simply rotating a single rotating shaft is enough to fix or release all carriers, making the operation simple, quick, and reducing labor intensity. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A catalyst carrier device for treating organic waste gas includes a housing 1, with an inlet pipe 2 and an outlet pipe 3 connected to both sides of the housing 1, and an internal chamber 4. The chamber 4 has multiple mounting slots 5 for mounting carrier components.

[0018] The carrier assembly includes a carrier body 6 and a frame 7, with the carrier body 6 movably mounted within the frame 7. Two T-shaped pins 8 are welded to one side of the frame 7. During installation, the frame 7 is inserted into the mounting groove 5, and the pins 8 extend out of the housing 1 through the insertion holes 18 on the side wall of the mounting groove 5.

[0019] A protective cover 9 is fixed to the outside of the housing 1, and multiple locking mechanisms are installed inside. Each locking mechanism includes a double-acting screw 10, which is rotatably connected to the protective cover 9 via a bearing seat. Each double-acting screw 10 is equipped with two moving blocks 11, which respectively engage with the positive and negative threaded sections of the screw. A wedge-shaped block 12 is fixed on the moving block 11, and a straight groove 13 is opened on it. The web shaft of the pin 8 is inserted into the straight groove 13.

[0020] The protective cover 9 also includes a rotating shaft 14, supported by bearings. Multiple first helical gears 15 are fixed to the rotating shaft 14, each meshing with a second helical gear 16, which is fixed to the end of a double-acting screw 10. Guide rods 19 are fixed between the side walls of the protective cover 9, and a moving block 11 is simultaneously fitted onto the guide rods 19 to ensure horizontal movement only. A cover 20 is hinged to the outside of the protective cover 9 for easy maintenance.

[0021] The inner wall of the mounting groove 5 is fitted with a sealing gasket 17, and the insertion hole 18 is fitted with a sealing ring to ensure a seal.

[0022] Work process: Mounting the carrier: Insert the carrier body 6 into the frame 7, and insert the entire assembly into the mounting slot 5, with the pin 8 passing through the insertion hole 18. Use a tool to rotate the rotating shaft 14, which drives all the bidirectional screws 10 to rotate synchronously through the helical gear set. The bidirectional screws 10 drive the two moving blocks 11 to move towards each other, and the wedge block 12 pulls the pin 8 through the straight slot 13, causing the frame 7 to press against the sealing gasket 17, thus completing the locking.

[0023] Disassembling the carrier: Rotate the shaft 14 in the opposite direction, and the double screw 10 will drive the moving block 11 to move in the opposite direction. The wedge block 12 will release the pin 8, and the carrier assembly can be taken out for replacement.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
