[0021] As Figure 1 , 2 Shown in Figures 3 and 4, a drying device for catalyst production includes a drying oven 1. A box door 18 is hinged to the front end of the drying oven 1. A sealing strip is arranged between the box door 18 and the drying oven 1. It also includes a material storage box 6. Springs 3 are fixedly connected to the inner bottom of the drying oven 1. The upper ends of the springs 3 are fixedly connected to a base 2. Limit plates 5 are fixedly connected to both sides and the rear end of the base 2. A plurality of material storage boxes 6 are detachably connected to the limit plates 5. The lower end of the base 2 is fixedly connected to a vibration motor 4 through a connecting frame and bolts. A hot air generator 7 is fixedly connected to the upper end of the drying oven 1 through bolts. The output end of the hot air generator 7 extends into the drying oven 1 through a pipeline and is fixedly connected to a rotary joint 8. A second air outlet pipe 10 is connected to the lower end of the rotary joint 8. First air outlet pipes 9 located on both sides of the limit plates 5 are connected to the second air outlet pipe 10. An air distribution plate 13 is connected to the inner side of the first air outlet pipe 9 and the second air outlet pipe 10. A motor 14 is fixedly connected to the upper end of the drying oven 1. The output end of the motor 14 is in transmission connection with the second air outlet pipe 10.

[0022] In order to monitor the temperature inside the drying oven 1 in real time, and at the same time facilitate the control box 19 to adjust the frequency of the hot air generator 7 in real time to control the drying temperature inside the drying oven 1, and avoid the problem that the drying effect and drying efficiency are not ideal due to too high or too low temperature, a temperature sensor 11 is fixedly connected to one side of the drying oven 1. A control box 19 is fixedly connected to the box door 18. The temperature sensor 11 is in communication connection with the control box 19. The vibration motor 4 and the hot air generator 7 are controlled by the control box 19. It should be noted that in this embodiment, the hot air generator 7 adopts a variable frequency hot air generator, which is an existing device, and its structure will not be described in detail in this text.

[0023] In order to drive the second air outlet 10 to rotate through the motor 14, the motor 14 is fixedly connected to the upper end of the drying box 1 through a connecting frame and bolts, the output end of the motor 14 penetrates the drying box 1 and is fixedly connected to a driving wheel 15, and the second air outlet 10 is fixedly connected to a driven wheel 16, and the driving wheel 15 and the driven wheel 16 are connected by a belt 17. It should be noted that in this embodiment, the motor 14 and the second air outlet 10 can also be connected by a transmission method such as a chain and a sprocket, gear meshing, etc., so as to achieve the rotation of the second air outlet 10.

[0024] In order to facilitate the disassembly and assembly of the material box 6 and improve work efficiency, the inner sides of the limiting plates 5 located on both sides of the base 2 are fixedly connected with clamping blocks 20 at intervals, and the two sides of the material box 6 are provided with clamping grooves 21, and the clamping grooves 21 are slidably engaged with the clamping blocks 20. In order to facilitate the installation of the material box 6 and the limiting plates 5 after the catalyst is placed, so that the second air outlet pipe 10 is located at the center of the material box 6 after installation, a notch is provided at the rear end of the material box 6 to allow the second air outlet pipe 10 to pass through.

[0025] In order to avoid danger caused by excessive pressure inside the drying box 1 during the drying process, a pressure relief valve 12 is fixedly connected to one side of the drying box 1. When the pressure inside the drying box 1 reaches a certain level, the pressure is automatically relieved.

[0026] In order to make the hot air blown out more evenly and ensure a better drying effect, the air uniformity plate 13 is a multi-layer metal wire ring structure.

[0027] It should be noted that, in this embodiment, the rotary joint 8 is an existing device that can realize the delivery of gas or liquid while realizing rotation, and its specific structure will not be described in detail in this article. At the same time, in this embodiment, the spring 3 adopts a spring with a relatively large elastic coefficient, so that the base 2 can achieve a small range of shaking.

[0028] The working process of this embodiment is as follows:

[0029] When carrying out the drying process of catalyst production, open the box door 18, take out the material box 6, put the catalyst to be dried into the material box 6, and then put the material boxes 6 into the drying box 1 one by one. When placing, align the card slots 21 on both sides of the material box 6 with the clamping blocks 20 inside the limiting plate 5 to slidably connect the material box 6. During the connection process, the second air outlet pipe 10 passes through the notch opened on the material box 6 and is placed at its central position. Then close the box door 18, set the temperature value on the control box 19, and start the vibration motor 4 to run. Under the action of the vibration motor 4, the catalyst in the material box 6 can be vibrated and dispersed to ensure a good drying effect. Synchronously start the hot air generator 7 to run. The hot air generated passes through the rotary joint 8 from the output end pipe of the hot air generator 7 and enters the first air outlet pipe 9 and the second air outlet pipe 10, and is evenly dispersed from the air distribution plate 13. Synchronously start the motor 14 to run. The motor 14 drives the driving wheel 15 to rotate. Under the driving action of the belt 17, the driven wheel 16 is driven to rotate, and then the second air outlet pipe 10 and the first air outlet pipe 9 are driven to rotate, so that the first air outlet pipe 9 rotates along the outside of the material box 6, and the second air outlet pipe 10 rotates in the middle of the material box 6, so as to ensure the drying uniformity. During the drying process, the temperature sensor 11 monitors the internal temperature of the drying box 1 in real time and feeds the data back to the control box 19, so that the control box 19 can adjust the operating frequency of the hot air generator 7 in real time to ensure the best drying temperature. When the pressure in the drying box 1 is too high, the pressure relief valve 12 automatically relieves the pressure. After drying, open the box door 18 and take out the material box 6.
