[0002] The VOC industrial catalyst mesh belt drying furnace adopts a mesh belt conveyor structure. When working, the carrier filled with slurry is first conveyed into the furnace through the mesh belt, and the carrier is dried by hot air through the hot air circulation system in the furnace. During the drying process, the high-speed circulating air generated by the circulating fan is heated by the electric heating tube installed in the furnace to dry the moisture of the workpiece during coating.

[0003] A patent application with publication number CN220269975U discloses an environmentally friendly denitrification catalyst tunnel furnace drying device, including a base, and a connecting seat bolted to the top of the base, a controller is installed on the front of the base, an adsorption seat is bolted to both sides of the base, and the adsorption seat is also bolted to the connecting seat. The device is provided with an air guide cavity on both the base and the connecting seat, and with the use of air guide holes, when the air guide fan and the heating tube inside the air guide cavity are started, the heated airflow will enter the interior of the device through the air guide holes, so that it contacts the product on the conveyor belt, and both sides of the product will be heated, so that the product can be heated more evenly.

[0023] Specifically, a VOC industrial catalyst mesh belt drying furnace of the scheme is mainly used for drying VOC industrial catalysts. The VOC industrial catalyst is composed of an active component, a carrier 5 and an additive, and the preparation of the VOC industrial catalyst includes the steps of preparing the carrier, loading the active component, molding the catalyst and activating the catalyst. During the activation process of the catalyst, a drying furnace is required to remove impurities and moisture in the catalyst. Prior to this, the active component and other additives need to be mixed together to form a slurry of a certain concentration, and then the slurry is poured into the interior 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 not fixed and can be cylindrical or square. The attached figure shows only one of them. In this method, the slurry needs to be poured in from the holes. After the slurry pouring is completed, the carrier 5 filled with the slurry is called a catalyst, so that the catalyst is formed. The catalyst is then transferred to the surface of the conveyor mesh belt 11 for transportation. When the catalyst moves to the inside of the heating furnace 2, it can be dried. During the drying process, the circulating fan in the heating furnace 2 will generate high-speed circulating air, which will pass through the electric heating tube provided in the heating furnace 2. After being heated by the electric heating tube, the catalyst can be dried. The drying process will be coordinated with the conveyor mesh belt 11. When the conveyor mesh belt 11 transfers the catalyst to the discharge platform 3, the drying of the catalyst is completed. However, during the drying process, if the slurry does not completely fill the carrier 5, then This will result in the unfilled areas being unable to provide sufficient active sites, making it impossible for these areas to carry out effective catalytic conversion when drying, and the internal conditions of the carrier 5 cannot be observed from the outside, and the diameter of the holes opened in the carrier 5 is too small, which makes it easy for the slurry to be filled unevenly. For this reason, an adjustment structure 4 is designed. When in use, the carrier 5 is first placed on the placement plate 423 in the placement tube 407. At this time, the upper end of the carrier 5 will extend to the outside of the placement tube 407, and then the placement tube 407 is started. The placement tube 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 adjustment frame 401, the lower sealing plate 416 is started, and the two lower sealing plates 416 will move away from each other, so that the carrier 5 can The two upper sealing plates 417 will move away from each other, so that the passage between the material holding frame 402 and the carrier 5 is completely opened. The material holding frame 402 is filled with slurry, and the slurry will enter the hole of the carrier 5. The motor at one end of the second intermittent tooth 428 is started, and the second intermittent tooth 428 is meshed with the fixed gear 427, so that the fixed gear 427 drives the placement plate 423 to rotate. After rotating for a certain angle, the second intermittent tooth 428 will no longer mesh with the fixed gear 427, and then the coil spring 426 will release the elastic force and drive the placement plate 423 to reset. This reciprocating motion will cause the carrier 5 to shake up and down.Thus, the slurry inside can be filled evenly, and since the carrier 5 is inside the adjustment frame 401, this shaking will not cause the slurry to overflow. Then, when the slurry completely fills the carrier 5, the carrier 5 filled with the slurry is called a catalyst. The placement cylinder 407 is started again, and the placement cylinder 407 will drive the catalyst to move downward. When it moves to the lowest end in the lifting frame 404, the connecting rod 425 is started, and the connecting rod 425 will drive the placement plate 423 to flip, so that the catalyst can fall steadily on the surface of the conveyor mesh belt 11. By setting the placement cylinder 407, the slurry can be completely filled with the carrier 5.

[0024] like Figures 1 to 9 As shown, the adjustment structure 4 also includes: a pressing plate 414, which is slidably connected to the inside of the material holding frame 402; an upper rack 418, which is arranged at one end of the upper sealing plate 417, and an upper sliding rod 419 is arranged inside the upper rack 418; a lower rack 415, which is arranged at one end of the lower sealing plate 416, and a lower sliding rod 422 is arranged inside the lower rack 415; a connecting bar 421, one end of the connecting bar 421 is slidably connected to the arc surface of the upper sliding rod 419, and the other end of the connecting bar 421 is slidably connected to the arc surface of the lower sliding rod 422, and the connecting bar 421 is in the initial state. The lower part is located at one end close to the upper sealing plate 417; the first intermittent tooth 413, the first intermittent tooth 413 is rotatably connected to the inside of the adjusting frame 401, and the first intermittent tooth 413 is meshed with the lower rack 415; the screw 405, the screw 405 is rotatably connected to the inside of the lifting frame 404; the lifting rod 406, the lifting rod 406 is arranged inside the lifting frame 404 near one end of the screw 405; the lifting block 408, one end of the lifting block 408 is threadedly connected to the screw 405, and the other end of the lifting block 408 slides on the surface of the lifting rod 406, and the lifting block 408 is connected to the placement tube 407.

[0025] Specifically, when it is necessary to move the placement cylinder 407 upward, the screw 405 is started to rotate. Since one end of the lifting block 408 is threadedly connected to the screw 405 and the other end slides on the surface of the lifting rod 406, the placement cylinder 407 will drive the carrier 5 to move upward. Then, when the upper end of the carrier 5 moves to the inside of the adjustment frame 401, the first intermittent tooth 413 is started to rotate. The first intermittent tooth 413 will mesh 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 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 open. 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 surface 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 connected to the material holding frame 402, and the pressing plate 414 will be started. The pressing plate 414 will move downward, thereby assisting in pressing the slurry into the interior of the carrier 5.

[0026] like Figures 1 to 4 As shown, the internal rotation of the adjustment frame 401 is connected to the rotating shaft 435, the interior of the adjustment frame 401 is provided with an abutment cover 411, and the abutment cover 411 is connected to 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 on the arc surface of the first intermittent tooth 413.

[0027] Specifically, by setting the abutment cover 411, when the carrier 5 enters the interior of the adjustment frame 401, it will first contact the abutment cover 411 and make the abutment cover 411 rotate around the rotating shaft 435. During the 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.

[0028] like Figures 1 to 5 As shown, a return spring 420 is sleeved on the surface of the upper sliding rod 419 , and one end of the return spring 420 is connected to the upper rack 418 .

[0029] Specifically, by providing the reset spring 420 , when the lower sealing plate 416 and the upper sealing plate 417 need to be reset, the reset spring 420 will release the elastic force, thereby reducing the friction of the connecting strip 421 and assisting in driving the upper rack 418 to reset.

[0030] like Figures 1 to 8 As shown, tooth plates 409 are provided at both ends of the lifting frame 404 , and a rotating tooth 410 is provided at one end of the connecting rod 425 , and the rotating tooth 410 is meshed with the tooth plate 409 .

[0031] Specifically, by setting the tooth plate 409 and the rotating teeth 410, when the placement cylinder 407 moves downward and the catalyst needs to be placed on the conveyor mesh belt 11, the rotating teeth 410 will contact and engage with the tooth plate 409, so that the rotating teeth 410 drive the connecting rod 425 to rotate, thereby driving the placement plate 423 to flip, so that the catalyst can fall smoothly on the conveyor mesh belt 11.

[0032] like Figures 1 to 9 As shown, a plurality of buffer pads 424 are provided on the surface of the placement plate 423 .

[0033] Specifically, by providing the 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 drives the carrier 5 to shake, the buffer pad 424 can also protect the carrier 5 from being bumped. Embodiment 2

[0034] like Figures 1 to 10 As shown, compared with Example 1, another embodiment of the present invention is: a transport frame 403 is provided at one end of the lifting frame 404, and one end of the transport frame 403 is located at the upper end of the placement cylinder 407, and a plurality of conveying shafts 429 are provided inside the transport frame 403.

[0035] Specifically, by setting up the transport frame 403, when drying work is required, it is only necessary to place the arc surface of the carrier 5 on the arc surface of the conveying shaft 429, and then start the conveying shaft 429 to transport the carrier 5, and finally make the carrier 5 fall inside the placement cylinder 407, thereby realizing continuous conveying and loading.

[0036] like Fig.10 As shown, a limiting bar 430 is provided on the surface of the transport frame 403 , and a plurality of auxiliary rollers 431 are rotatably connected inside the limiting bar 430 .

[0037] Specifically, by setting the limit bar 430, when the carrier 5 is placed on the conveying shaft 429 for conveying, the limit bar 430 can not only limit the moving direction of the carrier 5, but the auxiliary roller 431 located inside the limit bar 430 can also reduce the friction between the carrier 5 and the limit bar 430, so that the conveying of the carrier 5 is smoother.

[0038] like Figure 10 to Figure 11 As shown, a scraping frame 432 is provided on the surface of the limiting strip 430 , and a plurality of brushes 433 are provided inside the scraping frame 432 .

[0039] Specifically, by setting up a scraping frame 432, when the carrier 5 is transported through the conveying shaft 429, the carrier 5 will move to the inner wall of the scraping frame 432 to be wrapped. Since the carrier 5 is still moving at this time, the brush 433 located inside the scraping frame 432 will scrape the outer wall of the carrier 5, thereby scraping off impurities and dust, thereby preventing these impurities from gasifying in the heating furnace 2 and ultimately affecting the internal environment of the heating furnace 2.

[0040] like Figure 10 to Figure 11 As shown, one end of the surface of the limiting strip 430 close to the scraping frame 432 is rotatably connected to a positioning roller 434 , and the plane of the end of the positioning roller 434 is perpendicular to the plane of the end of the auxiliary roller 431 .

[0041] Specifically, by providing the positioning roller 434 , when the carrier 5 moves to contact with the positioning roller 434 , the positioning roller 434 is started, and the positioning roller 434 will drive the carrier 5 to rotate, so that all parts of the arc surface of the carrier 5 can contact with the brush 433 .

[0042] Working principle: When the VOC industrial catalyst needs to be dried, first place the arc surface of the carrier 5 on the arc surface of the conveying shaft 429, then start the conveying shaft 429, and then the carrier 5 can be conveyed, and finally the carrier 5 falls inside the placement cylinder 407 and is located on the placement plate 423. At this time, the upper end of the carrier 5 will extend to the outside of the placement cylinder 407, and the screw 405 is started to rotate. Since one end of the lifting block 408 is threadedly connected to the screw 405, and the other end slides on the surface of the lifting rod 406, the placement cylinder 407 at this time will drive the carrier 5 to move upward. When the carrier 5 enters the interior of the adjustment frame 401, it will first contact the abutment cover 411, and make the abutment cover 411 move with the rotating shaft 435 as the axis. The first intermittent tooth 413 will be meshed 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, 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 surface 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 connected to the material holding frame 402, and the pressing plate 414 will be started, and the pressing plate 414 will move downward. The second intermittent tooth 428 is moved to assist in pressing the slurry into the interior of the carrier 5, and at the same time, the motor at one end of the second intermittent tooth 428 is started, and the second intermittent tooth 428 will mesh with the fixed gear 427, so that the fixed gear 427 drives the placement plate 423 to rotate, and after rotating a certain angle, the second intermittent tooth 428 will no longer mesh with the fixed gear 427, and then the coil spring 426 will release the elastic force and drive the placement plate 423 to reset. This reciprocating motion will cause the carrier 5 to shake up and down, so that the internal slurry can be evenly filled, and because the carrier 5 is inside the adjustment frame 401, this shaking will not cause the slurry to overflow, and then when the slurry completely fills the carrier 5, the carrier 5 filled with slurry is called a catalyst. The catalyst is then moved to the bottom of the lifting frame 404, and the rotating gear 410 contacts and meshes with the tooth plate 409, so that the rotating gear 410 drives the connecting rod 425 to rotate, thereby driving the placing plate 423 to flip, so that the catalyst can fall steadily on the conveyor mesh belt 11 for transportation. When the catalyst moves to the inside of the heating furnace 2, it can be dried. During the drying process, the circulating fan in the heating furnace 2 will generate high-speed circulating wind, which will pass through the electric heating tube arranged in the heating furnace 2. After being heated by the electric heating tube, the catalyst can be dried. The drying process will cooperate with the transportation of the conveyor mesh belt 11.When the conveyor belt 11 transfers the catalyst to the discharge platform 3, the drying of the catalyst is completed.
