[0002] The spray dryer for Chinese herbal extract is the application of centrifugal spray drying technology in the drying of specific materials (Chinese herbal extract). It is also a drying device that uses a high-speed centrifugal atomizer to disperse the material into fine particles, fully contact it with hot air, and complete instant drying to form a powdered finished product. This drying equipment is a spray dryer specifically used to solve the problem of Chinese herbal extracts and plant extracts. The spray drying tower is the main component and has a large volume. Although the inner wall can be automatically cleaned after spray drying, due to the large variety of Chinese medicines and the high viscosity of the powder extract, in the spray drying process of Chinese herbal extracts, the viscous extract will adhere to the inner wall of the spray drying tower and is difficult to clean.

[0003] At present, it is generally adopted to fill the tower with water and stir, which needs to be repeated many times, or to clean it manually. Not only does it waste a lot of water, but the stirring speed is limited, the flushing force is small, it is difficult to clean and the cleaning efficiency is low. Manual cleaning is inefficient, difficult to operate, and the cleaning is not in place. Utility Model Content

[0006] Optionally, a through hole is formed on a peripheral wall of the nozzle, and the nozzle sleeve is provided with a collar, and the collar is provided with at least one nozzle connected to the through hole.

[0007] Optionally, the spray head is rotatably connected to a collar, and the nozzle on the collar has at least one deflection setting.

[0008] Optionally, a plurality of water spray holes 2 are provided at the end of the spray head.

[0009] Optionally, a hollow shaft is connected to the end of the cylinder, and a sealing ring and a bearing are centrally arranged between the outer wall of the hollow shaft and the inner wall of the hollow rotating head.

[0010] Optionally, one end of the cylinder away from the hollow rotating head is a necked structure.

[0011] Optionally, the cylinder is connected to the connecting pipe via a clamp.

[0012] Optionally, the connecting pipe is a hose.

[0013] Optionally, the spray drying tower inner wall cleaning device further comprises a support frame and two fixed pulleys arranged on the support frame, and the connecting pipe passes through the middle of the two fixed pulleys.

[0014] Optionally, a guide hole for the connecting pipe to pass through is opened on the support frame, and a sleeve aligned with the guide hole is provided on the support frame.

[0015] The beneficial effect of the utility model is that the connecting pipe can be extended from the top to the bottom of the spray drying tower, one end of the connecting pipe is connected to the water supply device, water is sprayed from the nozzle, and a force is applied to the nozzle. Since the nozzle is deflected relative to the hollow rotating head, a torque is generated, and the torque causes the hollow rotating head to rotate around the cylinder, so that the high-pressure water column sprayed from the nozzle can circumferentially wash the inside of the spray drying tower. The water spray hole of the hollow rotating head sprays a high-pressure water column to wash the bottom plate of the spray drying tower. The extension amount of the connecting pipe is properly controlled to wash the entire inner wall of the spray drying tower. Since the high-pressure water column can more easily wash away the powder on the inner wall of the tower, it not only saves more water, but also improves the cleaning efficiency and cleans more thoroughly.

[0021] Compared with the prior art, the spray drying tower inner wall cleaning device provided by the utility model can extend from the top to the bottom of the spray drying tower through the connecting pipe 30. One end of the connecting pipe 30 is connected to the water supply device. Water is sprayed from the nozzle 21 to apply force to the nozzle 21. Since the nozzle 21 is offset relative to the hollow rotating head 20, a torque is generated. The torque causes the hollow rotating head 20 to rotate around the cylinder 10, so that the high-pressure water column sprayed from the nozzle 21 can circumferentially flush the interior of the spray drying tower. The water spray hole 201 of the hollow rotating head 20 sprays a high-pressure water column to flush the bottom plate of the spray drying tower. The extension amount of the connecting pipe 30 is properly controlled to flush the entire inner wall of the spray drying tower. Since the high-pressure water column can more easily flush away the powder on the inner wall of the tower, it not only saves more water, but also improves the cleaning efficiency and cleans more thoroughly.

[0022] In one embodiment, see Figure 3 The peripheral wall of the nozzle 21 is provided with a through hole 212, and the nozzle 21 is sleeved with a collar 22, and the collar 22 is provided with at least one nozzle 23 connected with the through hole 212. Specifically, the nozzle 21 is a head cylinder 10 structure, the water spray hole 201 is opened at the end of the head, and 1-4 or more than 4 through holes 212 are evenly opened in the circumferential direction of the cylinder wall, so that the water flow can be ejected from the nozzle 21 through the through hole 212 and the nozzle 23 in sequence, thereby increasing the high-pressure water column in multiple directions and further improving the cleaning efficiency.

[0023] For further information, see Figure 2 The nozzle 21 is connected to the collar 22 in a sealed rotational manner, and the nozzle 23 on the collar 22 has at least one deflection setting. Specifically, the nozzle 21 is connected to the collar 22 in a sealed rotational manner to naturally form an annular cavity, and one end of each through hole 212 extends to the annular cavity, so that water can be ejected from the nozzle 21 through the through hole 212, the annular cavity and the nozzle 23 in sequence, and the deflected nozzle 23 can make the collar 22 rotate, so that the high-pressure water column ejected from the nozzle 23 rotates to wash the inner wall of the spray drying tower, further improving the cleaning efficiency.
