Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of catalyst drying, and particularly relates to a VOC industrial catalyst mesh belt type drying furnace. BACKGROUND

[0002] The VOC industrial catalyst mesh belt type drying furnace adopts a mesh belt type conveying structure, and when working, the carrier filled with slurry is conveyed into the furnace through the mesh belt, and hot air drying is performed on the carrier through a hot air circulation system in the furnace. When drying, the high-speed circulating air generated by the circulating fan is heated by the electric heating pipe arranged in the furnace, and then the moisture on the workpiece during coating is dried.

[0003] A patent application with the publication number CN220269975U discloses an environmental protection denitration catalyst tunnel furnace drying device, which comprises a base, a connecting seat bolted to the top of the base, a controller installed on the front of the base, and an adsorption seat bolted to the two sides of the base and bolted to the connecting seat. The device is provided with a gas guide cavity on the base and the connecting seat, and is used in cooperation with a gas guide hole. When the gas guide fan and the heating pipe inside the gas guide cavity are started, the heated air flow will enter the inside of the device through the gas guide hole, so that the product on the conveying mesh belt is contacted and heated, and the product is heated more uniformly.

[0004] The above-mentioned scheme still has some problems in actual application. When the VOC industrial catalyst is dried by the above-mentioned drying device, the honeycomb carrier suitable for the VOC industrial catalyst needs to be placed in the inside of the tunnel furnace for conveying and drying.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments. Embodiment one

[0035] Specifically, the VOC industrial catalyst mesh belt drying furnace of the scheme is mainly used for drying VOC industrial catalysts. The VOC industrial catalysts are composed of active components, carriers 5 and additives, and the preparation of the VOC industrial catalysts includes the preparation of carriers, the loading of active components, the molding of catalysts and the activation of catalysts. In the activation process of the catalysts, the drying furnace is needed to remove impurities and moisture in the catalysts. Before that, the active components and other additives need to be mixed together to form a slurry of a certain concentration, and then the slurry is poured into the inside of the carrier 5. The carrier 5 is a honeycomb carrier 5 with a plurality of holes on the surface. The shape of the carrier 5 is indefinite and can be cylindrical or square. The drawing shows only one of them. The slurry needs to be poured into the holes. After the pouring of the slurry is completed, the carrier 5 filled with the slurry is called a catalyst, so that the catalyst is molded, and then the catalyst is transferred to the surface of the conveying mesh belt 11 for conveying. When the catalyst moves to the inside of the heating furnace 2, drying treatment can be performed. When drying, the circulating fan in the heating furnace 2 will generate high-speed circulating air. The circulating air will pass through the electric heating pipe arranged in the heating furnace 2. After being heated by the electric heating pipe, the catalyst can be dried. The drying treatment will cooperate with the conveying of the conveying mesh belt 11. When the conveying mesh belt 11 transfers the catalyst to the discharge table 3, the drying of the catalyst is completed. However, if the slurry does not completely fill the carrier 5 during the drying process, the unfilled areas will not provide enough active sites, so that these areas cannot be effectively catalytically converted during drying. The inside of the carrier 5 cannot be observed from the outside, and the hole diameter of the carrier 5 is too small, so that the filling of the slurry is prone to unevenness. Therefore, the adjusting structure 4 is designed. In use, first, place the carrier 5 on the placement plate 423 in the placement cylinder 407. At this time, the upper end of the carrier 5 will extend to the outside of the placement cylinder 407. Then start the placement cylinder 407. The placement cylinder 407 will drive the carrier 5 to move upwards. Then, when the upper end of the carrier 5 moves to the inside of the adjusting frame 401, start the lower sealing plate 416. The two lower sealing plates 416 will move away from each other, so that the carrier 5 can pass through the adjusting frame 401. At this time, start the upper sealing plate 417 again. The two upper sealing plates 417 will move away from each other, so that the channel between the material containing frame 402 and the carrier 5 is completely open. The inside of the material containing frame 402 is placed with the slurry. At this time, the slurry will enter the holes of the carrier 5. At this time, start the motor at one end of the second intermittent tooth 428. The second intermittent tooth 428 will be engaged with the fixed gear 427, so that the fixed gear 427 drives the placement plate 423 to rotate. After rotating for some angles, the second intermittent tooth 428 will no longer be engaged with the fixed gear 427. Then the coil spring 426 will release the elastic force and drive the placement plate 423 to reset. This reciprocating motion will make the carrier 5 shake up and down.Thus, the internal slurry can be evenly filled, and since the carrier 5 is inside the adjusting frame 401, such shaking will not cause the slurry to overflow, and then when the slurry completely fills the carrier 5, this carrier 5 filled with slurry is called a catalyst, and the placing cylinder 407 is started again, which will drive the catalyst to move downward, and when moving to the lowermost end inside the lifting frame 404, the connecting rod 425 is started, which will drive the placing plate 423 to flip, so that the catalyst can smoothly fall on the surface of the conveying mesh belt 11, and by arranging the placing cylinder 407, the slurry can completely fill the carrier 5.

[0036] As shown in Figures 1 to 9 The adjusting structure 4 further comprises a pressing plate 414 slidably connected inside the material containing frame 402, an upper rack 418 arranged at one end of the upper sealing plate 417, an upper sliding rod 419 arranged inside the upper rack 418, a lower rack 415 arranged at one end of the lower sealing plate 416, a lower sliding rod 422 arranged inside the lower rack 415, a connecting strip 421, one end of which is slidably connected to the arc surface of the upper sliding rod 419, the other end of which is slidably connected to the arc surface of the lower sliding rod 422, and the connecting strip 421 is located close to one end of the upper sealing plate 417 in the initial state, a first intermittent tooth 413 rotatably connected inside the adjusting frame 401, which is engaged with the lower rack 415, a screw rod 405 rotatably connected inside the lifting frame 404, a lifting rod 406 arranged at one end of the lifting frame 404 close to the screw rod 405, a lifting block 408, one end of which is threadedly connected with the screw rod 405, and the other end of which is slidably arranged on the surface of the lifting rod 406, and the lifting block 408 is connected with the placing cylinder 407.

[0037] Specifically, when the placing cylinder 407 needs to be moved upward, the screw rod 405 is started to rotate, since one end of the lifting block 408 is threadedly connected with the screw rod 405 and the other end slides on the surface of the lifting rod 406, at this time, the placing cylinder 407 will drive the carrier 5 to move upward, and then when the upper end of the carrier 5 moves to the inside of the adjusting frame 401, the first intermittent tooth 413 is started to rotate, the first intermittent tooth 413 will engage with the lower rack 415, thereby driving the lower sealing plate 416 to move through the lower rack 415, so that the carrier 5 can pass through the lower sealing plate 416, at the same time, the connecting strip 421 will slide on the surface of the upper sliding rod 419 away from the upper sealing plate 417, so that the upper sealing plate 417 will not be opened, when the carrier 5 passes through the lower sealing plate 416, the connecting strip 421 will move to the end of the surface of the upper sliding rod 419 away from the upper sealing plate 417, and drive the upper rack 418 to move, so that the upper sealing plate 417 can be opened, at this time, the upper end of the carrier 5 will be communicated with the material containing frame 402, the pressing plate 414 is started to move downward, thereby assisting the paste to be pressed into the inside of the carrier 5.

[0038] As shown in Figures 1 to 4 , the inside of the adjusting frame 401 is rotationally connected with a rotating shaft 435, the inside of the adjusting frame 401 is provided with an abutting cover 411, and the abutting cover 411 is connected with the rotating shaft 435, the surface of the rotating shaft 435 is sleeved with a chain 412, and the other end of the chain 412 is sleeved with the arc surface of the first intermittent tooth 413.

[0039] Specifically, by arranging the abutting cover 411, when the carrier 5 enters the inside of the adjusting frame 401, it will first contact the abutting cover 411, and make the abutting cover 411 rotate around the rotating shaft 435, in the process of rotation, the rotating shaft 435 will drive the first intermittent tooth 413 to rotate through the chain 412, thereby realizing the opening of the lower sealing plate 416 and the upper sealing plate 417.

[0040] As shown in Figures 1 to 5 , the surface of the upper sliding rod 419 is sleeved with a return spring 420, and one end of the return spring 420 is connected with the upper rack 418.

[0041] Specifically, by arranging the return spring 420, when the lower sealing plate 416 and the upper sealing plate 417 need to be reset, the return spring 420 will release the elastic force, thereby reducing the friction of the connecting strip 421, and assisting the upper rack 418 to reset.

[0042] As shown in Figures 1 to 8 , both ends of the lifting frame 404 are provided with tooth plates 409, one end of the connecting rod 425 is provided with a rotating tooth 410, and the rotating tooth 410 engages with the tooth plate 409.

[0043] Specifically, by setting the toothed plate 409 and the rotating tooth 410, when the placement cylinder 407 moves downward and needs to place the catalyst on the conveyor belt 11, the rotating tooth 410 will contact and mesh with the toothed plate 409, so that the rotating tooth 410 drives the connecting rod 425 to rotate, thereby causing the placement plate 423 to flip, so that the catalyst can fall smoothly onto the conveyor belt 11.

[0044] like Figures 1 to 9 As shown, the surface of the placement plate 423 is provided with several buffer pads 424.

[0045] Specifically, by setting a buffer pad 424, when the carrier 5 is placed on the surface of the placement plate 423, the buffer pad 424 can reduce the friction between the carrier 5 and the placement plate 423, and when the placement plate 423 causes the carrier 5 to shake, the buffer pad 424 can also protect the carrier 5 from being bumped. Example 2

[0046] like Figures 1 to 10 As shown in the first embodiment, another embodiment of the present invention is as follows: one end of the lifting frame 404 is provided with a transport frame 403, and one end of the transport frame 403 is located at the upper end of the placement cylinder 407. The transport frame 403 is provided with a plurality of conveying shafts 429 inside.

[0047] Specifically, by setting up the transport frame 403, when drying is required, simply place the arc surface of the carrier 5 on the arc surface of the conveyor shaft 429, then start the conveyor shaft 429 to transport the carrier 5, and finally let the carrier 5 fall into the inside of the placement cylinder 407, thus achieving continuous conveying and feeding.

[0048] like Figure 10 As shown, the surface of the transport frame 403 is provided with a limiting strip 430, and several auxiliary rollers 431 are rotatably connected inside the limiting strip 430.

[0049] Specifically, by setting the limiting strip 430, when the carrier 5 is placed on the conveying shaft 429 for conveying, the limiting strip 430 can not only limit the movement direction of the carrier 5, but the auxiliary roller 431 located inside the limiting strip 430 can also reduce the friction between the carrier 5 and the limiting strip 430, making the conveying of the carrier 5 smoother.

[0050] like Figures 10 to 11 As shown, the surface of the limiting strip 430 is provided with a scraping frame 432, and the inside of the scraping frame 432 is provided with several brushes 433.

[0051] Specifically, by setting the scraping frame 432, when the carrier 5 is conveyed by the conveying shaft 429, the carrier 5 will move to the inner wall of the scraping frame 432, so as to be wrapped. Since the carrier 5 is still moving at this time, the brush 433 inside the scraping frame 432 will scrape the outer wall of the carrier 5, so as to scrape off the impurities and dust, thereby avoiding that the impurities are gasified in the heating furnace 2, and finally affecting the internal environment of the heating furnace 2.

[0052] As shown in Figures 10 to 11 The limiting strip 430 is rotationally connected with a position adjusting roller 434 at an end close to the scraping frame 432, and a plane at the end of the position adjusting roller 434 is perpendicular to a plane at the end of the auxiliary roller 431.

[0053] Specifically, by setting the position adjusting roller 434, when the carrier 5 moves to contact the position adjusting roller 434, the position adjusting roller 434 is started, and the position adjusting roller 434 will drive the carrier 5 to rotate, so that all parts of the arc surface of the carrier 5 can contact the brush 433.

[0054] Work principle: when the VOC industrial catalyst needs to be dried, firstly, the arc surface of the carrier 5 is placed on the arc surface of the conveying shaft 429, then the conveying shaft 429 is started, so that the carrier 5 can be conveyed and finally falls into the inside of the placing cylinder 407 and is located on the placing plate 423, at this time, the upper end of the carrier 5 will extend to the outside of the placing cylinder 407, the screw 405 is started to rotate, because one end of the lifting block 408 is threadedly connected with the screw 405 and the other end slides on the surface of the lifting rod 406, so that the placing cylinder 407 will drive the carrier 5 to move upwards at this time, when the carrier 5 enters the inside of the adjusting frame 401, it will first contact the abutting cover 411 and make the abutting cover 411 rotate around the rotating shaft 435, in the process of rotation, the rotating shaft 435 will drive the first intermittent tooth 413 to rotate through the chain 412, the first intermittent tooth 413 will engage with the lower rack 415, so that the lower sealing plate 416 is driven to move through the lower rack 415, so that the carrier 5 can pass through the lower sealing plate 416, at the same time, the connecting strip 421 will slide on the surface of the upper sliding rod 419, so that the upper sealing plate 417 will not be opened, when the carrier 5 passes through the lower sealing plate 416, the connecting strip 421 will move to the end of the upper sliding rod 419 away from the upper sealing plate 417 and drive the upper rack 418 to move, so that the upper sealing plate 417 can be opened, at this time, the upper end of the carrier 5 will be communicated with the material containing frame 402, the pressing plate 414 is started to move downwards, so as to assist the slurry to be pressed into the inside of the carrier 5, and at the same time, the motor at one end of the second intermittent tooth 428 is started, the second intermittent tooth 428 will engage with the fixed gear 427, so that the fixed gear 427 drives the placing plate 423 to rotate, and after rotating for some angles, the second intermittent tooth 428 will no longer engage with the fixed gear 427, then the coil spring 426 will release the elastic force and drive the placing plate 423 to reset, this reciprocating motion will make the carrier 5 shake up and down, so that the slurry in the inside can be uniformly filled, and because the carrier 5 is in the inside of the adjusting frame 401, the shaking will not cause the slurry to overflow, then when the slurry is completely filled in the carrier 5, this slurry-filled carrier 5 is called catalyst, the screw 405 is started to rotate again, the placing cylinder 407 will drive the catalyst to move downwards, when moving to the lowermost end in the lifting frame 404, the rotating tooth 410 will contact and engage with the tooth plate 409, so that the rotating tooth 410 drives the connecting rod 425 to rotate, thereby driving the placing plate 423 to overturn, so that the catalyst can be stably dropped on the conveying mesh belt 11 for conveying, when the catalyst moves to the inside of the heating furnace 2, it can be dried, when drying, the circulating fan in the heating furnace 2 will produce high-speed circulating wind, the circulating wind will pass through the electric heating pipe arranged in the heating furnace 2, after being heated by the electric heating pipe, the catalyst can be dried, the drying treatment will be matched with the conveying of the conveying mesh belt 11,When the conveyor belt 11 has transferred the catalyst to the discharge station 3, the drying of the catalyst is complete.
