Embodiment 1

[0020] like figure 1 , 2 , 3, the fine nozzle of the present invention includes: a material pipe 1, an air pipe 2, a front cover 3, a rear end cover 4, a spray nozzle 5, and a heating device 6.

[0021] The middle part of the fine nozzle is material tube 1, material tube 1 is covered with air duct 2, a cavity is formed between material tube 1 and air duct 2, the cavity is sealed by front and rear end covers, and the rear end of material tube 1 passes through connecting part 8 It is connected with the feeding pipe, and the rear end of the air pipe 2 is connected with the air supply pipe 7.

[0022] The front end of the material pipe 1 is equipped with a spray nozzle 5, and the front cover 3 is set on the spray nozzle 5 and adapted to it. The center of the front cover 3 is provided with an inner hole 11, and the outer ring of the inner hole 11 has a number of small holes 12 distributed along the circumference. , each inner hole 11 communicates with a small hole 12 through a gr...

Embodiment 2

[0027] On the basis of the structure of Embodiment 1, the present invention is provided with a bearing seat at the connection between the material pipe 1, the feeding pipe and the rear end cover 4, and there is a rotation gap between the front end cover 3 and the spray nozzle 5. The external gear is installed at the end, and the external gear is connected with the driving motor through the transmission mechanism. The motor drives the material pipe 1 and the material injection nozzle 5 to rotate, and the fineness of the material injection can be adjusted by adjusting the rotating speed.

[0028] Working process of the present invention is as follows:

[0029] Turn on the fan, the air is blown into the cavity from the air supply pipe, and blows out through the outer edge of the material trough of the spray nozzle. The material rotates to throw out the material particles. The heating device can be turned on as needed.

Abstract

The invention provides a fine spray nozzle, which is applicable to spraying fine particle materials and can be applied in multiple fields. The middle part of the fine spray nozzle is a material pipe. An air pipe is sheathed outside the material pipe. A chamber which is formed between the material pipe and the air pipe is sealed by a front end cover and a rear end cover. The rear end of the material pipe is connected with a material supply pipe. The rear end of the air pipe is connected with an air supply pipe. A material spray nozzle is installed at the front end of the material pipe. The front end cover is sheathed on the material spray nozzle and is matched with the material spray nozzle. An inner hole is formed in the center of the front end cover. A plurality of small holes are circumferentially distributed in the outer ring of the inner hole. The inner hole is communicated with each small hole through a trench. The inner hole of the front end cover is sheathed on the material spray nozzle. The material spray nozzle is columnar and a plurality of material channels are axially arranged along the peripheral wall of the material spray nozzle.

Description

technical field [0001] The invention relates to a fine nozzle, which can be applied in the fields of chemical industry, automobile manufacturing, construction and the like. Background technique [0002] At present, the structure of the existing fine nozzles adopts the nozzle type, and the spraying particles are large and the fineness uniformity is poor, which cannot meet the requirements of fine particles such as toner. It is necessary to improve the existing fine nozzles. Contents of the invention [0003] The invention provides a fine nozzle, which is suitable for spraying fine particle materials and can be applied in various fields. [0004] The purpose of the present invention is achieved by the following scheme: [0005] A fine nozzle, the middle part of the fine nozzle is a material tube, the material tube is covered with an air duct, the cavity formed between the material tube and the air duct is sealed by the front and rear end covers, the rear end of the material...
