Description

Technical Field

[0001] The utility model relates to the technical field of static electricity elimination, in particular to a static electricity eliminator for powder feeding and packaging. Background Technique

[0002] In the chemical industry field, in the pneumatic conveying pipeline of polyolefin materials, due to the contact and separation between the materials and the pipeline, charge transfer occurs to make the materials charged, and an electric field is formed after accumulation in the silo. At this time, if the dust and combustible gas concentrations in the silo reach certain values, the energy of static electricity discharge may trigger deflagration of the silo. Therefore, a static electricity eliminator for powder feeding and packaging is needed.

[0003] There is a prior static electricity eliminator for powder materials (application number: 202021363930.0), which automatically detects the polarity and magnitude of the ions required to eliminate static electricity according to the polarity of the charges generated by the materials, and generates the ions required to eliminate static electricity. When the ions enter the pipeline, under the action of the electric field force, opposite charges attract each other and neutralize. However, there are still problems. When collecting powder raw materials, the powder raw materials need to be discharged into a packaging bag through a conveying pipe for packaging. Since the collision between the powder raw materials and the conveying pipe often generates static electricity, the above device realizes the static electricity elimination work by setting an electrode seat, an instrument ventilation duct, a current limiting resistor, a discharge electrode and a high-voltage wire. When transporting powder raw materials, due to the action of static electricity, some powders will agglomerate, which is not convenient for workers to break up the large static agglomerates, and thus easily affects the subsequent static electricity elimination effect. Moreover, when using the conveying pipe, it needs to be connected to an external pipeline, and it is not convenient to perform double sealing on the connection position. Therefore, when a single seal is damaged, leakage is likely to occur. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that it is not convenient for workers to break up large static agglomerates, which easily affects the subsequent static electricity elimination effect, and it is not convenient to perform double sealing on the connection position, so when a single seal is damaged, leakage is likely to occur, and a static electricity eliminator for powder feeding and packaging is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

The upper part of the outer wall of the second gear is rotatably connected to the inner wall of the top of the housing through a bearing.

A rubber sleeve is closely attached to the outer wall of the vertical pipe. The outer wall of the rubber sleeve is fixedly connected to the inner wall of the pipe.

[0009] Preferably, the upper end and the lower end of a rubber ring are respectively attached to the top of the upper first circular plate and the bottom of the second circular plate.

The discharge electrodes in one row of electrode seats are connected to the positive high-voltage output end of an external AC automatic balancing static eliminator, and the other row is connected to the negative high-voltage output end of the external AC automatic balancing static eliminator. The powder falls, and then the electric field force is used to complete the static elimination work, which is convenient for the staff to disperse the large static agglomerates and avoid affecting the subsequent static elimination effect;
