Description
Technical Field
[0001] The utility model relates to the technical field of denitrified catalyst production, in particular to a denitrified catalyst processing and feeding device. Background Art
[0002] Honeycomb denitrification catalyst is an important tool used in selective catalytic reduction (SCR) technology. It is mainly used for industrial flue gas treatment, especially nitrogen oxide (NOx) emission control in power plants. The honeycomb denitrification catalyst provides a large reaction surface area through its porous structure, allowing the gas to fully contact the catalyst, thereby improving the denitrification efficiency.
[0003] In the existing technology, during the processing of honeycomb denitrified catalysts, the catalyst strips produced need to be dried. However, when drying the strips, the catalyst strips are often directly stacked and dried in a drying device. When the strips are tightly stacked together, the catalyst in the middle of the stack may not be fully exposed to the hot air, resulting in uneven drying and poor drying results. How to invent a denitrified catalyst processing and loading device to solve these problems has become a pressing issue for those skilled in the art. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides a de-catalyzed catalyst processing and feeding device, which aims to solve the problem of poor drying effect when strip catalysts are closely stacked together.
[0005] The utility model is achieved in that:
[0006] The utility model provides a de-catalyzed catalyst processing and feeding device, comprising a base, a moving mechanism, a lifting mechanism and a feeding rack arranged on the base, wherein a conveying platform is installed on the outer wall of the base, a drying device is installed above the base near the conveying platform, a placement seat is installed at one end of the base near the conveying platform entrance, strip catalysts and asbestos strips are stacked on the placement seat respectively, and the lifting mechanism is installed in the moving mechanism.
[0007] The loading rack is installed at the lower end of the lifting mechanism, a first suction cup is installed at the bottom of the loading rack, and a plurality of clamping frames are symmetrically installed on both sides of the loading rack.
[0008] Preferably, the moving mechanism drives the lifting mechanism to slide, and the lifting mechanism drives the loading rack to move in a vertical direction.
[0009] By adopting the above technical solution, the loading rack is controlled by the moving mechanism and the lifting mechanism to lift the catalyst and asbestos strips on the placement seat, making it convenient to stack the catalyst on the conveyor table and transport it to the drying device for drying, saving the time of manual stacking and improving the drying efficiency.
[0010] Preferably, slide grooves are provided on the outer walls of both sides of the loading rack, and double-headed screws are installed on the inner walls of the slide grooves, and both ends of the double-headed screws are slidably connected to the inner walls of the slide grooves.
[0011] Preferably, a pulley is installed at one end of the double-headed screw, and a belt is connected between the two pulleys for transmission. A motor is installed on one side of the loading rack, and the output end of the motor is fixedly connected to one end of one of the double-headed screws.
[0012] Preferably, a slider is installed at one end of the clamping frame in a group of three, wherein the inner wall of the slider at the lower end of the two clamping frames close to the edge is threadedly connected to the two ends of the double-headed screw, and the outer wall of the two sliders is slidably connected to the inner wall of the slide groove.
[0013] Preferably, the outer wall of the slider at the lower end of the clamping frame near the midpoint of the slide is fixedly connected to the inner wall of the slide, the inner wall of the slider is rotatably connected to the outer wall of the double-headed screw, and the side wall of the clamping frame is provided with an oblique groove.
[0014] Preferably, a second suction cup is installed on the inner wall of the clamping frame, an air pipe is installed on the second suction cup, and a telescopic hose that is interconnected is installed between the air pipes on the multiple second suction cups, and an air nozzle is installed at one end of the telescopic hose.
[0015] By adopting the above technical solution, the loading rack first clamps multiple strip catalysts, then clamps the asbestos strips again, and then moves them to the conveyor table for placement, so that the strip catalysts are placed on the asbestos strips. The above operation is repeated to stack the strip catalysts and asbestos strips, thereby increasing the contact area between the strip catalysts and the air, thereby improving the drying effect.
[0016] The beneficial effects of the utility model are:
[0017] While the first suction cup is set to clamp the strip catalyst, the clamping frame cooperates with the second suction cup to clamp the asbestos strip and fix it under the strip catalyst. In the process of stacking the catalyst on the conveyor table, the strip catalysts are suspended to increase the contact area between the hot air and the surface of the strip catalyst, so that the heat is more evenly transferred to various parts of the strip catalyst, which helps to improve the drying speed and efficiency, and avoid local over-drying or under-drying, thereby improving the overall quality of the material after drying.

A conveying platform 4 is installed on the outer wall of the base 1. A drying device 5 is installed above the base 1 near the conveying platform 4. A placement seat 6 is installed at one end of the base 1 near the entrance of the conveying platform 4. Strip catalysts 7 and asbestos strips 8 are stacked on the placement seat 6 respectively. The lifting mechanism 3 is installed in the moving mechanism 2.
[0028] The loading rack 9 is installed at the lower end of the lifting mechanism 3 , a first suction cup 10 is installed at the bottom of the loading rack 9 , and a plurality of symmetrical clamping frames 16 are installed on both sides of the loading rack 9 .
[0029] Furthermore, the moving mechanism 2 drives the lifting mechanism 3 to slide, and the lifting mechanism 3 drives the loading rack 9 to move in the vertical direction.
[0030] It should be noted that: when transporting the strip catalyst 7, the loading rack 9 is controlled to move by the cooperation of the moving mechanism 2 and the lifting mechanism 3, and the strip catalyst 7 is adsorbed by the first suction cup 10 under the loading rack 9, and then the strip catalyst 7 is lifted and moved to the input end of the conveying platform 4. The above operation is repeated until the stacking height of the strip catalyst 7 reaches the requirement. At this time, the conveying platform 4 is started to allow the catalyst to enter the interior of the drying device 5 for drying. At this time, the subsequent strip catalysts 7 can be stacked again and placed at the entrance of the conveying platform 4 to wait for the next batch of drying, saving the time of manually stacking the strip catalysts 7, thereby improving the efficiency of catalyst drying.
[0031] Furthermore, a slide groove 12 is provided on the outer wall of the two sides of the loading rack 9, and a double-headed screw 13 is installed on the inner wall of the slide groove 12. The two ends of the double-headed screw 13 are slidably connected to the inner wall of the slide groove 12, and a pulley 14 is installed at one end of the double-headed screw 13. A belt 15 is connected between the two pulleys 14 for transmission. A motor 11 is installed on one side of the loading rack 9, and the output end of the motor 11 is fixedly connected to one end of one of the double-headed screws 13. A slider 17 is installed at one end of a clamping frame 16 in a group of three, wherein the inner wall of the slider 17 at the lower end of the two clamping frames 16 near the edge and the double-headed screw are connected. The two ends of the rod 13 are threadedly connected, the outer walls of the two sliders 17 are slidably connected to the inner wall of the slide groove 12, the outer wall of the slider 17 at the lower end of the clamping frame 16 near the midpoint of the slide groove 12 is fixedly connected to the inner wall of the slide groove 12, the inner wall of the slider 17 is rotatably connected to the outer wall of the double-headed screw 13, the side wall of the clamping frame 16 is provided with an inclined groove 22, the inner wall of the clamping frame 16 is installed with a second suction cup 18, the second suction cup 18 is installed with an air pipe 19, and telescopic hoses 20 that are interconnected are installed between the air pipes 19 on the multiple second suction cups 18, and an air nozzle 21 is installed at one end of the telescopic hose 20.
[0032] It should be noted that: after the strip catalyst 7 is clamped, the loading rack 9 moves to the top of the asbestos strip 8. At this time, the loading rack 9 is moved downward, and the multiple clamping frames 16 at the lower end thereof respectively restrict the asbestos strip 8. In the process of moving downward, the inclined groove 22 at the edge of the clamping frame 16 is inserted into the gap between the asbestos strips 8, which facilitates the movement and separation of the asbestos strips 8 and the clamping of the clamping frame 16. Then, the second suction cup 18 is activated to fix the asbestos strip 8 in the clamping frame 16, and then the loading rack is moved downward by the cooperation of the moving mechanism 2 and the lifting mechanism 3. 9 moves to the top of the entrance of the conveying platform 4, starts the motor 11 to make the clamping frames 16 at both ends drive the asbestos strip 8 to move to both sides, and then closes the first suction cup 10 and the second suction cup 18 in sequence so that the strip catalyst 7 is first placed on the asbestos strip 8, and when the second suction cup 18 is closed, the asbestos strip 8 and the strip catalyst 7 are stacked on the conveying platform 4 at the same time, thereby completing the stacking of the strip catalyst 7. The asbestos strip 8 arranged under the strip catalyst 7 increases the contact area between the strip catalyst 7 and the air, thereby improving the drying effect.
[0033] The working principle of this de-catalyzed catalyst processing and feeding device:
[0034] When transporting the strip catalyst 7, the loading rack 9 is controlled to move by the cooperation of the moving mechanism 2 and the lifting mechanism 3, and the strip catalyst 7 is adsorbed by the first suction cup 10 under the loading rack 9, and then the loading rack 9 is moved to the top of the asbestos strip 8. At this time, the loading rack 9 is moved downward and the multiple clamping frames 16 at its lower end respectively restrict the asbestos strip 8. During the downward movement, the inclined groove 22 on the edge of the clamping frame 16 is inserted into the gap between the asbestos strips 8, which facilitates the movement and separation of the asbestos strips 8 and the clamping of the clamping frame 16. Then, the second suction cup 18 is started to fix the asbestos strip 8 in the clamping frame 16, and then the loading rack 9 is moved to the conveying platform by the cooperation of the moving mechanism 2 and the lifting mechanism 3. 4, start the motor 11 to make the clamping frames 16 at both ends drive the asbestos strips 8 to move to both sides, then close the first suction cup 10 and the second suction cup 18 in sequence so that the strip catalyst 7 is first placed on the asbestos strip 8, and when the second suction cup 18 is closed, the asbestos strip 8 and the strip catalyst 7 are stacked on the conveying platform 4 at the same time, thereby completing the stacking of the strip catalyst 7, repeat the above operation to marten the strip catalyst 7 until the height is appropriate, and support the catalyst by the asbestos strips 8 arranged between adjacent strip catalysts 7 to suspend the catalyst, thereby increasing the infiltration of hot air and the contact area between the strip catalyst 7 and the air, so that the strip catalyst 7 can be evenly heated, thereby improving the drying effect.
