[0001] This utility model belongs to the field of catalyst transfer technology, specifically a feeding and conveying device for transferring SCR denitrification catalyst. Background Technology

[0002] The feeding conveyor for SCR denitrification catalyst transfer is a device specifically designed for transporting and storing deactivated catalysts. It primarily addresses the potential injury risks associated with close-range manual operation and improves production efficiency. This device typically includes a cleaning tank and a conveyor system, achieving automated transport via infeed and discharge conveyors, replacing the traditional manual loading and unloading process. Current feeding conveyors for SCR denitrification catalyst transfer lack height adjustment functionality. The inability to adjust the height of the conveyor increases the time required for operators to remove the catalyst, wasting significant manpower and hindering catalyst handling in various environments. Therefore, a feeding conveyor for SCR denitrification catalyst transfer with adjustable height is needed. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a feeding and conveying device for SCR denitrification catalyst transfer. It solves the problem that the feeding and conveying device for SCR denitrification catalyst transfer does not have the function of adjusting the height. When feeding the catalyst on the transfer device, the inability to adjust the height of the transfer device leads to the process of operators removing the catalyst, which wastes a lot of manpower and is not conducive to feeding the catalyst in different environments.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding and conveying device for transferring SCR denitrification catalyst, comprising a transport vehicle body, a connecting plate snapped onto the inner wall of the transport vehicle body, a connecting block fixedly connected to the bottom side of the connecting plate, two rotating arms hinged to both sides of the connecting block, a first U-shaped frame hinged to the bottom end of the rotating arms, a threaded rod threaded onto the first U-shaped frame, the threaded rod having threads in opposite directions, a motor installed at one end of the threaded rod, the motor being fixedly connected to the transport vehicle body, a bearing installed at one end of the threaded rod, one side of the bearing being fixedly connected to the inner wall of the transport vehicle body, a partition plate fixedly connected to the connecting plate, and three support plates installed on both sides of the partition plate.

[0005] As a further embodiment of this utility model: four first support legs are fixedly connected to the bottom side of the transport vehicle body, and a second U-shaped frame is snapped into the first support leg, with a pulley hinged to the bottom side of the second U-shaped frame.

[0006] As a further embodiment of this utility model: a sliding groove is provided on one side of the second U-shaped frame, a column is engaged with the inner wall of the sliding groove, the column is engaged with the first support leg, a handle is fixedly connected to one end of the column, a spring is installed on one side of the handle, and one end of the spring is fixedly connected to the first support leg.

[0007] As a further embodiment of this utility model: a base plate is provided below the pulley, and four drive cylinders are installed on the bottom side of the base plate, with a base fixedly connected to the bottom side of the drive cylinders.

[0008] As a further embodiment of this utility model: a bracket is provided on one side of the support plate, a conveyor belt is installed on the bracket, and four second support legs are fixedly connected to the bottom side of the bracket.

[0009] As a further embodiment of this utility model: a plurality of heat dissipation grooves are provided on the support plate, a first limiting plate is fixedly connected to the support plate, and two second limiting plates are installed on one side of the first limiting plate, and the second limiting plates are fixedly connected to the support plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This feeding and conveying device for transferring SCR denitrification catalyst, by setting up a connecting plate, connecting block, rotating arm, first U-shaped frame, threaded rod, motor, partition plate and support plate, allows the operator to start the motor to drive the threaded rod to rotate when feeding the catalyst in different environments. Because there are threads in opposite directions on the threaded rod, the threaded rod causes the two first U-shaped frames to move in opposite directions. The first U-shaped frames pull the rotating arm to move, the rotating arm pulls the connecting block and connecting plate to move down, and the connecting plate pulls the partition plate and support plate to move down until it is adjusted to a suitable height. This facilitates the rapid and convenient feeding of the catalyst in different environments, prevents the operator from wasting a lot of manpower when feeding the catalyst because the position of the catalyst is too high, and improves the convenience of feeding the catalyst.

[0012] 2. This feeding and conveying device for transferring SCR denitrification catalysts, by setting up a first support leg, a second U-shaped frame, pulleys, a chute, a column, a base plate, a handle, and a spring, allows the operator to hold and pull the handle when fixing the transport vehicle body. The handle causes the column to slide in the chute and stretches the spring until the column is completely separated from the second U-shaped frame. Under the action of gravity, the first support leg moves the transport vehicle body downward until the bottom side of the first support leg is in complete contact with the base plate. This facilitates quick and stable fixing of the transport vehicle body and prevents the transport vehicle body from accidentally sliding during feeding, which could lead to feeding failure. This improves the functionality and stability of the transfer device. Attached Figure Description

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a feeding and conveying device for transferring SCR denitrification catalyst, including a transport vehicle body 1, four first support legs 11 fixedly connected to the bottom side of the transport vehicle body 1, a second U-shaped frame 12 snapped into the first support legs 11, and a pulley 13 hinged to the bottom side of the second U-shaped frame 12.

[0019] A slide groove 14 is provided on one side of the second U-shaped frame 12. A column 15 is snapped into the inner wall of the slide groove 14. The column 15 is snapped into the first support leg 11. A handle 16 is fixedly connected to one end of the column 15. A spring 17 is installed on one side of the handle 16. One end of the spring 17 is fixedly connected to the first support leg 11. A connecting plate 2 is snapped into the inner wall of the transport vehicle body 1. A connecting block 3 is fixedly connected to the bottom side of the connecting plate 2. Two rotating arms 4 are hinged to both sides of the connecting block 3. A first U-shaped frame 5 is hinged to the bottom end of the rotating arms 4. A threaded rod 6 is threadedly snapped into the first U-shaped frame 5. The threaded rod 6 has threads in opposite directions. A motor 7 is installed at one end of the threaded rod 6. The motor 7 is fixedly connected to the transport vehicle body 1. A base plate 18 is provided below the pulley 13. Four drive cylinders 19 are installed on the bottom side of the base plate 18. A base 20 is fixedly connected to the bottom side of the drive cylinders 19. Because of the drive cylinders 19, when feeding the catalyst, the operator starts the drive cylinders 19 to push the base plate 18 upward until the support plate 10 is adjusted to a suitable height, which facilitates feeding different support plates 10 and improves the functionality of the transport device.

[0020] A bracket 21 is provided on one side of the support plate 10, and a conveyor belt 22 is installed on the bracket 21. Four second support legs 23 are fixedly connected to the bottom side of the bracket 21. Because of the conveyor belt 22, after the catalyst is placed on the conveyor belt 22, the operator starts the conveyor belt 22 to transport the catalyst to the support plate 10, which facilitates the rapid and convenient feeding of the catalyst, saves manpower and material resources, and improves the feeding efficiency. A bearing 8 is installed at one end of the threaded rod 6, and one side of the bearing 8 is fixedly connected to the inner wall of the transport vehicle body 1. Because of the bearing 8, the threaded rod 6 is limited while allowing the normal rotation of the threaded rod 6. To improve the stability of the threaded rod 6 during rotation, a partition plate 9 is fixedly connected to the connecting plate 2. Three support plates 10 are installed on both sides of the partition plate 9. Several heat dissipation grooves 24 are opened on the support plates 10. A first limiting plate 25 is fixedly connected to the support plate 10. Two second limiting plates 26 are installed on one side of the first limiting plate 25. The second limiting plates 26 are fixedly connected to the support plates 10. Because of the first limiting plate 25, the catalyst on the support plate 10 is limited, preventing the catalyst from accidentally sliding and falling during the transfer process, thus avoiding waste of resources and improving the stability of the transfer device during transfer.

[0021] The working principle of this utility model is as follows: When fixing the transport vehicle body 1, the operator holds the handle 16 and pulls it. The handle 16 drives the column 15 to slide in the slide groove 14 and stretches the spring 17 until the column 15 is completely separated from the second U-shaped frame 12. Under the action of gravity, the first support leg 11 drives the transport vehicle body 1 to move downward until the bottom side of the first support leg 11 is in complete contact with the bottom plate 18. When feeding the catalyst, the operator starts the drive cylinder 19 to push the bottom plate 18 upward until the support plate 10 is adjusted to a suitable position. After the catalyst is placed on the conveyor belt 22, the operator starts the conveyor belt 22 to transport the catalyst to the support plate 10. When feeding the catalyst in different environments, the operator starts the motor 7 to drive the threaded rod 6 to rotate. Because the threaded rod 6 has threads in opposite directions, the threaded rod 6 causes the two first U-shaped frames 5 to move in opposite directions. The first U-shaped frames 5 pull the rotating arm 4 to move, the rotating arm 4 pulls the connecting block 3 and the connecting plate 2 to move down, and the connecting plate 2 pulls the partition plate 9 and the support plate 10 to move down until the appropriate height is adjusted.
