Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a spray drying device for a catalyst carrier. Background Art

[0002] Spray dryers are still widely used in chemical, light, and food industries because of their special advantage of being able to directly produce powder products with uniform composition from solutions or suspensions. In the chemical industry, they are most commonly used in the dye industry.

[0003] Existing spray drying equipment is difficult to ensure that the liquid can be fully dried, so some people think of setting a hot air nozzle around the spray port to ensure that the atomized liquid can be fully dried. For example, Chinese utility model patent with announcement number CN219963954U specifically discloses a catalyst spray drying tower.

[0004] However, in actual use of the spray drying equipment for the catalyst, people will find that the powder produced after drying may directly adhere to the inner wall of the equipment, and the equipment is not provided with a cleaning structure inside, which easily causes a waste of raw materials and greatly reduces its practicality.

The water inlet is connected, a high-pressure air pump is arranged above the heater, the air intake of the high-pressure air pump is connected with the air outlet of the heater, the exhaust port of the high-pressure air pump is connected with an air pipe, and the air pipe is connected with the inlet of the nozzle; the slide rail is arranged on the back of the tank body, a screw rod is arranged inside the slide rail, the end of the screw rod is rotatably connected with the slide rail, a driving motor is arranged at the bottom of the slide rail, the driving shaft of the driving motor is connected with the screw rod, a slider is threadedly connected on the screw rod, a connecting plate is arranged on the slider, the connecting plate is vertically arranged, a top plate is arranged above the connecting plate, a connecting rod is arranged on the top plate, the connecting rod passes through the upper cover and is inserted into the tank body and connected with a scraper.

[0007] The raw material liquid in the liquid storage tank is pumped out by a water pump and sprayed out from the atomizing nozzle on the water distribution pipe. The hot air generated by the heater is sprayed out from the nozzle using a high-pressure air pump to dry the atomized liquid and produce powder.

[0008] When the inner wall of the tank needs to be cleaned, the drive motor is used to drive the screw rod to rotate, so that the screw rod drives the slider to move up and down. The slider moves up and down by the forward and reverse rotation of the screw rod. When the screw rod rotates clockwise, the slider is driven to move downward. When the screw rod rotates counterclockwise, the slider moves upward. The movement of the slider drives the scraper to move up and down to clean the inner wall of the tank. When the inner wall of the tank does not need to be cleaned, the scraper is located at the conical cover and fits with the upper cover.

[0009] Preferably, the scraper is annular so as to fit the inner wall of the tank.

[0010] Preferably, a discharge port is provided at a middle position below the tank body.

[0011] Preferably, a plurality of supporting legs are provided below the tank body near the outer side, and the provided supporting legs mainly play a supporting role.

[0012] Preferably, a water injection port is provided above the liquid storage tank, an end cover is provided on the water injection port, and the provided water injection port is used for adding raw material liquid.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model arranges a water distribution pipe and a nozzle on a conical cover, and uses a water pump to extract the raw material liquid in the liquid storage tank and spray it from the atomizing nozzle on the water distribution pipe, and then uses a high-pressure air pump to spray hot air from the nozzle to dry the atomized raw material to produce powder. When the inner wall of the tank body needs to be cleaned, the lead screw is driven by a driving motor to rotate, so that the lead screw drives the slider to move, and the slider drives the scraper to move up and down, so that the inner wall of the tank body is cleaned, avoiding the problem of waste caused by powder adhering to the tank body, thereby improving the practicality of the device.
