Description

Technical Field

[0001] The utility model relates to the technical field of catalyst processing, in particular to a spraying device for catalyst processing. Background Art

[0002] In the production and processing of catalysts, it is often necessary to immerse the catalyst carrier in a metal salt solution so that the active components are evenly distributed on the carrier. Currently, the impregnation of catalysts is mainly completed by means of an impregnation tank or a continuous impregnation device.

[0003] According to a spray device for catalyst processing disclosed in patent number CN 220737581 U, a hose is arranged above a cylindrical box, and multiple nozzles are arranged on the hose. The catalyst is placed at one end of the cylindrical box, and liquid is sprayed into the cylindrical cavity through the nozzle. The liquid is sprayed onto the surface of the catalyst carrier during the spiral conveying process. However, during the spiral conveying process, a large number of catalyst carriers are conveyed at one time. It is difficult to ensure that each catalyst carrier is completely adhered to the active component by directly spraying with the nozzle, resulting in insufficient catalyst impregnation and poor impregnation effect. For this reason, we propose a spray device for catalyst processing. Utility Model Content

[0024] It should be noted that the inclined first guide plate 4 can make the catalyst carrier placed thereon fall down under the action of gravity, so as to facilitate the movement of the catalyst carrier inside the spray box 1 .

[0025] Two second guide plates 5 are fixedly connected to the inner wall of the spray box 1 on one side away from the screw feeder 2, and the second guide plates 5 are arranged at an angle.

[0026] It should be noted that when the utility model is used, the catalyst to be impregnated is placed in the loading hopper at the bottom end of the screw feeder 2, and the catalyst is placed in the spray box 1 through the operation of the screw feeder 2. The catalyst carrier entering the spray box 1 is first on the surface of the first guide plate 4 at the top of the spray box 1. At the same time, the liquid inlet pipe 8 transports the active liquid, and the catalyst falls under the action of gravity. At the same time, the transported liquid is sprayed onto the catalyst carrier on its surface through the liquid spray port 7 on the surface of the first guide plate 4 and the second guide plate 5. At the same time, the nozzle 11 on the upper nozzle 10 sprays the active liquid from top to bottom onto the catalyst carrier. The catalyst travels along the S-shaped channel inside the spray box 1, is sprayed for a long time, and is finally placed in the columnar cavity 12, and the liquid is placed in the buffer box 18 through the liquid outlet 15, and finally refluxes to the external liquid storage tank through the reflux pipe 19 for recovery. The screw conveying rod 13 is controlled to rotate by controlling the drive motor 14 to discharge and collect the impregnated material through the discharge port 17.

[0027] A liquid inlet pipe 8 is installed on the top of the spray box 1, and two branch pipes 9 are formed at the ends of the liquid inlet pipe 8. The two branch pipes 9 are symmetrically fixedly connected to the two sides of the spray box 1. Two nozzles 10 are connected to the two inner walls of the spray box 1, and the nozzles 10 are located between the first material guide plate 4 and the second material guide plate 5. Nozzles 11 are equidistantly arranged at the bottom of the nozzles 10. The first material guide plate 4, the second material guide plate 5 and the nozzles 10 are all connected to the inside of the branch pipes 9.

[0028] It should be noted that the liquid inlet pipe 8 is connected to the supply port of the external active liquid, and the active liquid transported by the liquid inlet pipe 8 is placed in two branch pipes 9, and is respectively placed in the cavity 6 inside the first guide plate 4 and the second guide plate 5 through the two branch pipes 9, and finally sprayed from bottom to top through the liquid spray port 7 to the catalyst carrier thereon, and the active liquid inside the nozzle 10 is sprayed from top to bottom to the catalyst carrier through the nozzle 11, so that the catalyst carrier can be evenly sprayed.

A driving motor 14 is fixedly installed at the bottom end of the side wall of the spray box 1, and the output shaft end of the driving motor 14 extends into the spray box 1 and is fixedly connected to the spiral conveying rod 13. A discharge port 17 is provided at the end of the spray box 1, and the end of the spiral conveying rod 13 extends into the discharge port 17.

[0030] It should be noted that the control system set up in the device controls the driving motor 14 to work, which can rotate the spiral conveying rod 13. The rotation of the spiral conveying rod 13 can transport the sprayed catalyst carrier inside the columnar cavity 12 to the discharge port 17, and finally discharge and collect it through the discharge port 17.

[0033] The spray pipe 10 is fixedly mounted on the inner wall of the spray box 1 in a serpentine structure.

[0034] It should be noted that the corresponding two side walls of the first guide plate 4 and the second guide plate 5 are in contact with the two side walls of the spray box 1 to prevent the catalyst carrier from falling. The nozzle 10 is arranged in a serpentine structure, and a plurality of nozzles 11 are arranged at the bottom of the nozzle 10, which can spray liquid over a large range toward the catalyst carrier so that the catalyst carrier is evenly coated with the active liquid.
