[0061] like Figure 1 As shown, this embodiment provides a catalyst drying line, comprising:

[0062] Warehouse body 1;

[0063] A lower transport unit 2, wherein the lower transport unit 2 is arranged in the warehouse body 1;

[0064] An upper transport unit 3, wherein the upper transport unit 3 is disposed in the warehouse body 1 and is located above the lower transport unit 2, and the conveying direction of the upper transport unit 3 is opposite to that of the lower transport unit 2;

[0065] A lifting unit 4, wherein the lifting unit 4 is disposed in the warehouse body 1, and the lifting unit 4 is disposed near the discharge end of the lower transport unit 2 and the feed end of the upper transport unit 3;

[0066] A drying and heating unit 5 , wherein a plurality of the drying and heating units 5 are installed above the lower transport unit 2 and above the upper transport unit 3 , respectively.

[0067] The working principle and beneficial effects of the above technical solution are:

[0068] The present invention discloses a catalyst drying line, which adopts a lower transport unit 2 and an upper transport unit 3. The lower transport unit 2 and the upper transport unit 3 are foldably connected in a warehouse body 1, which reduces the length of the drying line and does not seriously occupy the factory area. A plurality of drying and heating units 5 are respectively installed above the lower transport unit 2 and above the upper transport unit 3 to dry the catalyst. The catalyst is fed into the warehouse body 1 from the feed end of the lower transport unit 2 and moves to the lifting unit 4 from the discharge end of the lower transport unit 2. The lifting unit 4 rises to lift the catalyst to the vicinity of the feed end of the upper transport unit 3. The catalyst moves from the discharge end of the upper transport unit 3 to the outside of the warehouse body 1. The feed end of the lower transport unit 2 and the discharge end of the upper transport unit 3 are both located outside the warehouse body 1. In this way, only one workstation is needed to complete loading and unloading, saving manpower.

[0069] In one embodiment, the feeding end of the lower transport unit 2 and the discharging end of the upper transport unit 3 are both arranged to extend out of the warehouse body 1 .

[0070] like Figure 2 As shown, in one embodiment, the inner wall of the warehouse body 1 is paved with a heat-insulating layer 6 , and a wind-moving motor 7 is installed on the top of the warehouse body 1 .

[0071] The working principle and beneficial effects of the above technical solution are:

[0072] The heat-insulating layer 6 prevents the heat in the warehouse body 1 from being lost, and the air-conveying motor 7 makes the heat generated by the drying and heating unit 5 evenly distributed in the warehouse body 1 .

[0073] like Figure 3 As shown, in one embodiment, it also includes:

[0074] Temperature sensors are arranged in the warehouse body 1 and are respectively located between the lower transport unit 2 and the drying and heating unit 5 and between the upper transport unit 3 and the drying and heating unit 5;

[0075] The processor 8 is connected with the temperature sensor, the drying and heating unit 5 , the lower transport unit 2 and the upper transport unit 4 .

[0076] The working principle and beneficial effects of the above technical solution are:

[0077] The temperature sensor is used to monitor the temperature in the bin body 1. When the temperature is too high or too low, the processor 8 reduces or increases the power of the drying and heating unit 5.

[0078] In one embodiment, the lower transport unit 2 comprises:

[0079] A frame, on which the drying and heating unit 5 is mounted;

[0080] A network chain belt, wherein the network chain belt is located in the frame;

[0081] Active roller and driven roller, the active roller and driven roller are connected to the frame, and the mesh chain belt is sleeved on the active roller and driven roller;

[0082] A driving motor, wherein the driving motor is connected to the frame, an output end of the driving motor is connected to the active roller, and the driving motor is connected to the processor 8;

[0083] The network chain belt support plate is connected to the frame and is arranged close to the inner top of the network chain belt.

[0084] In one embodiment, the upper transport unit 3 comprises:

[0085] A frame, on which the drying and heating unit 5 is mounted;

[0086] A network chain belt, wherein the network chain belt is located in the frame;

[0087] Active roller and driven roller, the active roller and driven roller are connected to the frame, and the mesh chain belt is sleeved on the active roller and driven roller;

[0088] A driving motor, wherein the driving motor is connected to the frame, an output end of the driving motor is connected to the active roller, and the driving motor is connected to the processor 8;

[0089] The network chain belt support plate is connected to the frame and is arranged close to the inner top of the network chain belt.

[0090] like Figure 4 As shown, in one embodiment, the lifting unit 4 includes:

[0091] Hydraulic lifting platform 41;

[0092] A rotating seat 42, wherein the rotating seat 42 is connected to the hydraulic lifting platform 41;

[0093] A conveyor 43, wherein the conveyor 43 is installed on the rotating seat 42;

[0094] The position sensor is installed on the conveyor 43 . The position sensor, the conveyor 43 , and the hydraulic lifting platform 41 are all connected to the processor 8 .

[0095] The working principle and beneficial effects of the above technical solution are:

[0096] The position sensor is used to detect whether the catalyst has moved to the transport lifting unit 4. The conveyor 43 transports the catalyst from the discharge end of the lower transport unit 2 to the lifting unit 4. When the position sensor detects the position signal of the catalyst, it sends it to the processor 8. The processor 8 sends a stop command to the lower transport unit 2 and a work command to the hydraulic lifting platform 41. When the hydraulic lifting platform 41 moves to be flush with the upper transport unit 3, the rotating seat 42 works, and the conveyor 43 rotates 180 degrees. The conveyor 43 works to move the catalyst from the lifting unit 4 to the feeding end of the upper transport unit 3.

[0097] In one embodiment, the hydraulic platform 41 includes:

[0098] A base and a mounting seat, wherein the rotating seat is connected to the mounting seat;

[0099] A first support rod 45 and a second support rod 46, wherein the first support rod 45 and the second support rod 46 are installed between the base and the mounting seat in a scissor-fork manner, wherein one end of the first support rod 45 is rotatably connected to the top of the base, and the other end of the first support rod 45 is slidably connected to the bottom end of the mounting seat, and one end of the second support rod 46 is slidably connected to the top of the base, and the other end of the second support rod 46 is rotatably connected to the bottom end of the mounting seat;

[0100] A hydraulic cylinder 47 , one end of which is connected to the first support rod 45 , and the other end of which is connected to the second support rod 46 , and the hydraulic cylinder 47 is connected to the processor 8 .

[0101] The working principle and beneficial effects of the above technical solution are:

[0102] The hydraulic cylinder 47 contracts, so that the bottom ends of the first support rod 45 and the second support rod 46 approach each other, the bottom end of the second support rod 46 slides toward the first support rod 45, and the top end of the first support rod 45 slides toward the second support rod 46, and the mounting seat is lifted.

[0103] like Figure 5 As shown, in one embodiment, the rotating seat 42 includes:

[0104] An installation chamber 421, wherein the installation chamber 421 is embedded in the installation seat, the bottom end of the installation chamber 421 is coplanar with the bottom end of the installation seat, and the bottom end of the installation chamber 421 is provided with an opening 420;

[0105] A rotating chamber 422, wherein the rotating chamber 422 is disposed in the mounting seat and is located above the mounting chamber 421;

[0106] A fixed circular groove 423, which is provided at the top of the mounting seat and is located above the rotating chamber 422;

[0107] A rotating circular table 424, wherein the rotating circular table 424 is rotatably connected to the fixed circular groove 423, and the conveyor 43 is connected to the rotating circular table 424;

[0108] A rotating shaft 425, the rotating shaft 425 is connected to the bottom end of the rotating truncated table 424, and the rotating shaft 425 is away from the rotating truncated table 424 and is respectively disposed through the rotating chamber 422 and the installation chamber 421;

[0109] A first bevel gear 426, wherein the first bevel gear 426 is disposed in the rotating chamber 422, and the first bevel gear 426 is connected to the rotating shaft 425;

[0110] A rotating motor 427, wherein the rotating motor 427 is disposed in the rotating chamber 422;

[0111] A second bevel gear 428, wherein the second bevel gear 428 is connected to an output end of the rotating motor 427, and the second bevel gear 428 is meshed with the first bevel gear 426;

[0112] A rotating inclined plate 429, the rotating inclined plate 429 is hinged on the opening 420, a return coil spring is connected to the hinged end of the rotating inclined plate 429, and the high end of the rotating inclined plate 429 is arranged close to the center end of the mounting seat;

[0113] A fixed transverse plate 481, wherein the fixed transverse plate 481 is disposed in the installation chamber 421, and the fixed transverse plate 481 is connected to the bottom end of the rotating shaft 425;

[0114] T-slots 482, two T-slots 482 are symmetrically connected to the bottom end of the fixed horizontal plate 481 with the rotating shaft 425 as the center;

[0115] Sliding blocks 483, the same number of the sliding blocks 483 are arranged in the T-slot 482, and the sliding blocks 483 are slidably connected in the T-slot 482;

[0116] A return spring 484, wherein the return spring 484 is disposed in the T-slot 482, one end of the return spring 484 is connected to the T-slot 482, and the other end of the return spring 484 is connected to the sliding block 483;

[0117] A lifting block 485, wherein the lifting block 485 is disposed in the installation chamber 421 and is disposed close to the rotating inclined plate 429;

[0118] The two support arms 486 are hinged on the lifting block 485 in a V shape, and the ends of the support arms 486 away from the lifting block 485 are penetrated by T-shaped slots 482 and rotatably connected to the sliding block 483.

[0119] The working principle and beneficial effects of the above technical solution are:

[0120] When the top end of the first support rod 45 slides to the position of the rotating inclined plate 429 at the bottom end of the mounting seat, the rotating inclined plate 429 gradually tends to be coplanar with the bottom end of the mounting chamber 421. At this time, the rotating motor 427 located in the rotating chamber 422 drives the conveyor 43 connected to the rotating circular table 424 to rotate through the second bevel gear 428 connected to its output end, the first bevel gear 426 meshing with the second bevel gear 428, the rotating shaft 425 connected to the first bevel gear 426, and the rotating circular table 424 connected to the rotating shaft 425. When the conveyor 43 completes a 180-degree rotation, at this time, the first support rod 45 just slides onto the rotating inclined plate 429, and the rotating inclined plate 429 is coplanar with the bottom end of the mounting chamber 421. The rotating inclined plate 429 presses the lifting block 485 to move towards the direction close to the fixed horizontal plate 481, thereby widening the angle between the two support arms 486 and causing the return spring 484 to be in the T-slot When the mounting seat is lowered, the top end of the first support rod 45 slides in the direction away from the rotating inclined plate 429. At this time, the rotating inclined plate 429 loses the force of the first support plate 45. Under the action of the reset spring and the reset coil spring, the rotating inclined plate 429 returns to its original state. The angle between the two supporting arms 486 becomes smaller, and the sliding block 483 moves away from the reset spring 484 end to release the inner wall of the mounting chamber 421. The rotating shaft 425 resumes rotation, and the rotating motor 427 drives the conveyor 43 to rotate 180 degrees again. At this time, due to the extension of the hydraulic cylinder 47, the mounting seat is lowered to the position of the lower transport unit 2.

[0121] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
