Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a heating and catalytic treatment device for waste gas from a tobacco factory. Background Technology

[0002] Heating catalytic treatment is a commonly used method for treating waste gas. The specific operation process is as follows: after pretreatment, the waste gas enters the heating catalytic equipment. Under the action of the catalyst, the organic matter in the waste gas undergoes an oxidative decomposition reaction at a relatively low temperature (generally 200-400℃). The catalyst can lower the activation energy of the reaction, accelerate the reaction process, and convert the organic matter into harmless substances such as carbon dioxide and water, thereby achieving the purification of the waste gas. In existing technologies, after prolonged use, the catalytic efficiency of the catalyst elements in the heating catalytic equipment decreases, requiring replacement.

[0003] When replacing the catalyst in traditional heating catalytic converters, the machine body usually requires complex operations due to the limitations of the equipment structure. Moreover, when replacing the catalyst, the operator needs to use tools to remove it, which is not only time-consuming and labor-intensive, but may also damage the structure where the catalyst is stored, increasing maintenance costs and time.

[0004] Therefore, there is a need for a tobacco factory exhaust gas heating and catalytic treatment device to solve the problems of the cumbersome process of starting the heating and catalytic equipment and the difficulty in removing and replacing the catalytic components inside the heating and catalytic equipment in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a heating and catalytic treatment device for waste gas from tobacco factories, so as to solve the problems in the prior art where the process of starting the heating and catalytic equipment is relatively cumbersome and the catalytic components inside the heating and catalytic equipment are not easy to remove and replace.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heating and catalytic treatment device for tobacco factory exhaust gas, comprising a heating and catalytic device, a placement frame fixedly connected inside the heating and catalytic device, a movable plate slidably connected inside the placement frame, a catalytic plate placed inside the placement frame, a through hole opened on the outer wall of the front end of the heating and catalytic device, a pushing mechanism provided on the outer wall of the rear end of the heating and catalytic device, and a sealing component for sealing the through hole provided on the outer wall of the front end of the heating and catalytic device;

[0007] The pushing mechanism includes a mounting shell, which is fixedly connected to the outer wall of the rear end of the heating catalytic device. A rotating shaft is rotatably connected between the inner walls on both sides of the mounting shell. Multiple evenly distributed cams are fastened to the outer surface of the rotating shaft. A force-bearing plate is slidably connected inside the mounting shell. Two parallel sliding rods are fixedly connected to the outer wall of the front end of the force-bearing plate. A first spring is fixedly connected between the center of the outer wall of the front end of the force-bearing plate and the outer wall of the rear end of the heating catalytic device.

[0008] It should be noted in the solution that the sealing assembly includes two symmetrically distributed slides, both of which are fixedly connected to the outer wall of the front end of the heating catalytic device. A guide rod is fixedly connected between the top and bottom surfaces of the slides. A sliding element is slidably sleeved on the outer surface of the guide rod. The same sealing door is fixedly connected between the two sliding elements. A second spring is sleeved on the outer surface of the guide rod. Two symmetrically distributed fixing blocks are fixedly connected to the bottom surface of the sealing door. A slot is opened on one side of the outer wall of each fixing block.

[0009] It is worth noting that a mounting base is fixedly connected to the middle position of the bottom of the front outer wall of the heating catalytic device. Two symmetrically distributed sliding grooves are opened on the front outer wall of the mounting base. A sliding plate is slidably connected inside the sliding groove. A third spring is fixedly connected between the outer wall of one side of the sliding plate and the inner side wall of the sliding groove. A plug rod that slides through the outer wall of one side of the mounting base and is adapted to the slot is fixedly connected to the outer wall of the other side of the sliding plate.

[0010] Furthermore, it should be noted that a motor is installed on the outer right side of the mounting housing, and two parallel handles are fixedly connected to the outer front end of the sealing door.

[0011] In a preferred embodiment, the outer walls of the front ends of the two slide rods slide through the inner wall of the rear end of the heating catalytic device and the inner wall of the rear end of the placement frame and are fixedly connected to the outer wall of the rear end of the moving plate. The bottom end and top end of the second spring are fixedly connected to the inner bottom surface of the corresponding slide block and the bottom surface of the sliding element, respectively.

[0012] In a preferred embodiment, the bottom surface of the fixing block and the outer wall of the insert rod away from the slide plate are both set as inclined surfaces and cooperate with each other. The output end of the motor rotates through the inner right wall of the mounting shell and is coaxially fixedly connected to the outer right wall of the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the action of the pushing mechanism, the cam rotates and squeezes the force plate. The force plate pushes the moving plate through the slide rod, pushing the catalyst plate out of the heating catalytic device through the through hole. This makes it easy for the staff to remove and replace the catalyst plate, effectively avoiding the problem that the catalyst components inside the heating catalytic device are not easy to remove and replace.

[0015] 2. By pulling the handle to move the sealing door downwards, the sealing door drives the fixing block to push the insert rod. When the fixing block moves to the slot and the insert rod coincide, the third spring pushes the insert rod into the slot, locking the sealing door and releasing the blockage of the through hole, making it easier for the staff to operate the catalyst plate. After the replacement is completed, push the sliding plate to separate the insert rod from the slot, and the second spring pushes the sealing door to reset and block the through hole. The operation is simple and effectively avoids the cumbersome process of starting the heated catalyst equipment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-4As shown, this utility model provides a technical solution, including a heating catalytic device 1, a placement frame 2 fixedly connected inside the heating catalytic device 1, a moving plate 3 slidably connected inside the placement frame 2, a catalytic plate 4 placed inside the placement frame 2, a through hole 5 opened on the outer wall of the front end of the heating catalytic device 1, a pushing mechanism 6 provided on the outer wall of the rear end of the heating catalytic device 1, and a sealing component 7 for sealing the through hole 5 provided on the outer wall of the front end of the heating catalytic device 1.

[0023] The driving mechanism 6 includes a mounting shell 61, which is fixedly connected to the outer wall of the rear end of the heating catalytic device 1. A rotating shaft 62 is rotatably connected between the inner walls on both sides of the mounting shell 61. Multiple evenly distributed cams 63 are fastened to the outer surface of the rotating shaft 62. A force plate 64 is slidably connected inside the mounting shell 61. Two parallel sliding rods 65 are fixedly connected to the outer wall of the front end of the force plate 64. A first spring 66 is fixedly connected between the center of the outer wall of the front end of the force plate 64 and the outer wall of the rear end of the heating catalytic device 1.

[0024] Further as Figure 1 and Figure 3 As shown, it is worth noting that the sealing assembly 7 includes two symmetrically distributed slides 71. Both slides 71 are fixedly connected to the outer wall of the front end of the heating catalytic device 1. A guide rod 72 is fixedly connected between the top and bottom surfaces inside the slides 71. A sliding member 73 is slidably sleeved on the outer surface of the guide rod 72. The same sealing door 74 is fixedly connected between the two sliding members 73. A second spring 75 is sleeved on the outer surface of the guide rod 72. Two symmetrically distributed fixing blocks 76 are fixedly connected to the bottom surface of the sealing door 74. A slot 77 is opened on one side of the outer wall of the fixing block 76.

[0025] Further as Figure 1 and Figure 4 As shown, it is worth noting that a mounting base 8 is fixedly connected to the middle position of the bottom of the front outer wall of the heating catalytic device 1. Two symmetrically distributed sliding grooves 9 are opened on the front outer wall of the mounting base 8. A sliding plate 10 is slidably connected inside the sliding grooves 9. A third spring 11 is fixedly connected between the outer wall of one side of the sliding plate 10 and the inner side wall of the sliding groove 9. A plug rod 12 that slides through the outer wall of one side of the mounting base 8 and is adapted to the slot 77 is fixedly connected to the outer wall of the other side of the sliding plate 10.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a motor 13 is installed on the outer right side of the mounting housing 61, and two parallel handles 14 are fixedly connected to the outer front end of the sealing door 74.

[0027] Further as Figure 2 and Figure 3As shown, it is worth noting that the outer walls of the front ends of the two slide rods 65 slide through the inner wall of the rear end of the heating catalytic device 1 and the inner wall of the rear end of the placement frame 2, and are fixedly connected to the outer wall of the rear end of the moving plate 3. The force plate 64 is pushed to move by the cam 63, and the force plate 64 pushes the moving plate 3 to move by the slide rods 65, so as to push the catalytic plate 4 out from the through hole 5. The bottom end and top end of the second spring 75 are fixedly connected to the inner bottom surface of the corresponding slide seat 71 and the bottom surface of the sliding member 73, respectively. The movement and reset of the sealing door 74 are realized by the elastic action of the second spring 75.

[0028] Further as Figure 2 and Figure 3 As shown, it is worth noting that the bottom surface of the fixing block 76 and the outer wall of the insert rod 12 away from the slide plate 10 are both set as inclined surfaces and cooperate with each other. When the sealing door 74 moves the fixing block 76 downward, the fixing block 76 pushes the insert rod 12 to move. When the fixing block 76 moves to the slot 77 and coincides with the insert rod 12, the insert rod 12 is inserted into the slot 77, limiting the sealing door 74, which makes it convenient for the staff to replace the catalyst plate 4. The output end of the motor 13 rotates through the inner right wall of the mounting shell 61 and is coaxially fixedly connected to the outer right wall of the rotating shaft 62, providing a power source for the rotation of the rotating shaft 62.

[0029] In summary: During operation, the pre-treated exhaust gas enters the heating catalytic device 1 for heating and catalytic treatment. When the catalytic plate 4 experiences prolonged use and its catalytic efficiency decreases, it needs to be replaced. During replacement, the operator holds the two handles 14 and pulls the sealing door 74 downwards. With the sliding cooperation of the guide rod 72 and the sliding member 73, the sealing door 74 moves the sliding member 73 and compresses the second spring 75. Simultaneously, the sealing door 74 moves the fixing block 76 downwards. During this movement, the fixing block 76 contacts the insertion rod 12, pushing it gradually into the sliding groove 9. The insertion rod 12 then drives the sliding plate 10 to compress the third spring 11. When the sealing door 74 moves the fixing block 76 to the slot 77 and coincides with the insertion rod 12, the elastic action of the third spring 11 pushes the insertion rod 12 into the slot 77, locking and limiting the sealing door 74. At this time, the sealing door 74 releases the blockage of the through hole 5, and the through hole 5 is fully exposed, making it convenient for the staff to operate the catalyst plate 4. After the catalyst plate 4 is replaced, simply push the two sliding plates 10 together. The two sliding plates 10 drive the two insertion rods 12 to separate from the two slots 77. Under the elastic action of the second spring 75, the sealing door 74 is pushed to move and reset, realizing the re-sealing of the through hole 5. The operation is simple and effectively avoids the problem of the cumbersome process when starting the heated catalytic equipment.

[0030] After operating the sealing door 74, the motor 13 is turned on to drive the rotating shaft 62 to rotate. The rotating shaft 62 drives multiple cams 63 to rotate synchronously. When the cams 63 rotate, they press the force plate 64. After the force plate 64 is subjected to force, it pushes the moving plate 3 to move inside the placement frame 2 through the slide rod 65. During the movement, the moving plate 3 pushes the catalyst plate 4 out through the through hole 5, making it easy for the staff to take the catalyst plate 4 out of the heating catalyst device 1. After the cam 63 rotates one revolution, it pushes the force plate 64 to reset under the elastic action of the first spring 66, so that the moving plate 3 is reset inside the placement frame 2. Then, the staff only needs to insert the replaced catalyst plate 4 into the heating catalyst device 1 through the through hole 5 to complete the replacement of the catalyst plate 4, which effectively avoids the problem of the catalyst components inside the heating catalyst device being difficult to remove and replace.

[0031] The motor 13 can be purchased from the market and is a mature technology in this field, which has been fully disclosed. Therefore, it will not be described again in the specification.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
