Problems solved by technology

However, the existing dust filter has the following problems in use, especially when the dust filter is blocked, the pressure in the dust filter will be too high and there may be a danger of explosion. It will cause damage to the main body of the dust filter device, and at the same time, the high-speed airflow and debris mixed in the high-speed airflow generated by the dust filter device during the explosion may also cause personal injury to the nearby staff; secondly, the existing dust filter device Basically, they are split-type structures, that is, the negative pressure part and the filter part are separated from each other, and then connected to each other through pipelines. High-speed operation makes it have a large working noise

Abstract

The invention discloses a dust filtering device. The dust filtering device comprises an air inlet, an air outlet, a material collecting chamber, a filtering chamber and a fan, wherein the air inlet, the filtering chamber, the fan and the air outlet are sequentially communicated; the dust filtering device is arranged in the filtering chamber; the fan is used for blowing the air in the filtering chamber to the air outlet; the material collecting chamber is arranged under the filtering chamber and is communicated with the filtering chamber; the side wall of the filtering chamber is provided withan explosion venting port; an explosion venting plate is arranged at the explosion venting port. The dust filtering device has the advantages that the structure is reasonable, the safety and reliability are realized, and the working noise is low.

Description

technical field [0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a dust filtering device for recovering powder paint in a powder spraying system. Background technique [0002] Powder spraying is to use the principle of high-voltage electrostatic corona electric field to connect a high-voltage negative electrode to the metal diversion mark on the head of the spray gun, and the workpiece to be sprayed is grounded to form a positive electrode, so that a strong electrostatic electric field is formed between the spray gun and the workpiece. When the compressed air used as the carrier gas sends the powder coating from the powder supply barrel to the guide rod of the spray gun through the powder pipe, due to the corona discharge generated by the guide rod connected to the high-voltage negative electrode, dense negative charges are generated near it. , so that the powder coating is negatively charged and enters the electrostatic...
