[0002] The solder cleaning agent is prepared by homogenizing a mixture of rosin powder, triolamine powder, and benzene hydrochloride powder with industrial alcohol. The mixing of powder raw materials is completed in a mixing tank to ensure that the powder raw materials are evenly proportioned when they are packaged. When the operator loads the powder raw materials into the mixing tank, the powder raw materials will float upward due to the influence of air pressure. After the operator inhales the powder raw materials, their respiratory health is affected. In addition, the scattered raw materials fall on the floor of the workshop and need to be cleaned frequently, and there will be secondary dust problems during cleaning. Summary of the invention

The front end of the sleeve extends to the outside of the breathable filter, the rotating shaft seal is installed in the sleeve, the telescopic rod is slidably installed on the outer end of the rotating shaft, the cross-section of the telescopic rod is arranged in a square structure, the tension spring is sleeved and installed on the telescopic rod, and a limit ring is also fixedly installed on the telescopic rod, the two ends of the tension spring are respectively fixedly connected to the limit ring and the rotating shaft, the outer end of the telescopic rod is fixedly installed on the cross-shaped bracket, the rubber strip and the brush are respectively fixedly installed on the transverse rod and the longitudinal rod of the cross-shaped bracket, and under the action of the tension of the tension spring, the rubber strip and the brush are always pressed on the breathable filter, the outer end of the rotating shaft extends to the outside of the stirring tank body, the output shaft of the driving motor is transmission-connected to the outer end of the rotating shaft, and a pipeline interface connected to the negative pressure cover is provided on the stirring tank body.

[0005] Furthermore, the rubber strip and the brush are both screwed and fixedly mounted on the cross-shaped bracket.

[0006] Furthermore, 2 to 4 pipeline interfaces are arranged in a circular array on the stirring tank body with the central axis of the sleeve as the center.

[0007] Compared with the prior art, the advantages of the utility model are: when the cleaning agent powder raw materials are loaded into the negative pressure mixing tank, the airflow at the feeding port on the top thereof flows toward the mixing tank body under the action of negative pressure, which will not cause the problem of the powder raw materials floating upward, thus avoiding harm to the respiratory health of the operator. The powder raw materials on the air filter are continuously scraped and cleaned by rotating the rubber strips and brushes, thereby avoiding blockage of the air filter, so that the air filter can always be in a ventilated state, thereby ensuring that the feeding port is always in a negative pressure state.

[0013] The utility model is described in detail below in conjunction with specific implementation methods:

[0014] like Figures 1 to 4The shown negative pressure stirring tank for solder cleaning agent powder comprises a stirring tank body 1, a motor bracket 2, a driving motor 21, a negative pressure cover 3, a ring 4, a rotating shaft 41, a telescopic rod 42, a tension spring 43, a rubber strip 5, a brush 6, a cross bracket 7 and a breathable filter 8. The stirring tank body 1 has a top feeding port 11 and a bottom discharge pipe 12, and a ball valve opened and closed by a controller is installed on the bottom discharge pipe 12. The motor bracket 2 is fixedly mounted on the outer wall of the stirring tank body 1, and the driving motor 21 is fixedly mounted on the motor bracket 2. The negative pressure cover 3 is sealed and fixedly mounted on the inner wall of the stirring tank body 1. The breathable filter 8 is fixedly mounted on the outer opening of the negative pressure cover 3. The middle part of the negative pressure cover 3 has a sleeve, and the rear end of the sleeve is fixedly mounted on the inner wall of the stirring tank body 1. The front end of the sleeve extends to the outside of the breathable filter 8, and the outside of the breathable filter 8 is sealed and fixedly connected to the front end of the sleeve. The rotating shaft 41 is rotatably and sealably mounted in the sleeve. The telescopic rod 42 is also rotatably installed in the sleeve, and the telescopic rod 42 is slidably installed at the outer end of the rotating shaft 41. The cross-section of the telescopic rod 42 is arranged in a square structure, and the outer end of the rotating shaft 41 is provided with a square hole with the telescopic rod 42, so that the rotating shaft 41 can drive the telescopic rod 42 to rotate synchronously, the tension spring 43 is sleeved and installed on the telescopic rod 42, and a limit ring 44 is also fixedly installed on the telescopic rod 42, and the two ends of the tension spring 43 are respectively fixedly connected with the limit ring 44 and the rotating shaft 41, the outer end of the telescopic rod 42 is fixedly installed on the cross-shaped bracket 7, and the rubber strip 5 and the brush 6 are respectively fixedly installed on the transverse rod and the longitudinal rod of the cross-shaped bracket 7.
