Recovery device for spraying of powder onto guardrail

Abstract

The invention discloses a recovery device for the spraying of powder onto a guardrail. The recovery device comprises a spraying room, an exhaust fan I, a feeding pipeline, a recovery tank, two rail plates, an upper plate, a weighing sensor, a supporting seat, a lower plate, a filtering bag and an exhaust fan II, wherein the exhaust fan I is fixedly connected to the top end of the spraying room; the feeding pipeline is fixedly connected with the outlet of the exhaust fan I; the other end, which is not connected with the exhaust fan I, of the feeding pipeline is fixedly connected onto the top wall of the recovery tank; the two rail plates are fixedly connected with the upper parts of the inner walls of the left and right sides of the recovery tank; rail grooves are formed in the end surfacesof the sides, facing the center of the recovery tank, of the two rail plates; the upper plate is slidably assembled between the two rail plates; the weighing sensor is fixedly connected to the bottomof the recovery tank; the supporting seat is fixedly connected with the upper part of the weighing sensor; the lower plate is arranged on the upper end surface of the supporting seat; the filtering bag is connected between the upper plate and the lower plate; and the exhaust fan II is mounted on the right end surface of the recovery tank. By adoption of the above structure, the recovery device disclosed by the invention has the advantages of being safe and environmentally friendly as well as achieving resource conservation.

Description

technical field [0001] The invention relates to a recovery device for guardrail powder spraying, which is applied in the technical field of guardrail spraying. Background technique [0002] Guardrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places and other occasions. After the guardrails are processed, in order to improve the surface performance of the guardrails, powder coating is often used to spray powder coatings on the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the guardrail to form a powdery coating. However, when the guardrail is sprayed with powder, there will be a certain amount of powder coating that cannot be adsorbed on the surface of the guardrail, and it is suspended in the air. Forming solid dust particles, if these are directly discharged into the atmosphere, not only will the environment be ...

[0002] Guardrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places and other occasions. After the guardrails are processed, in order to improve the surface performance of the guardrails, powder coating is often used to spray powder coatings on the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the guardrail to form a powdery coating. However, when the guardrail is sprayed with powder, there will be a certain amount of powder coating that cannot be adsorbed on the surface of the guardrail, and it is suspended in the air. Form solid dust particles. If these are directly discharged into the atmosphere, not only will it pollute the environment, but the powder coating will also be directly wasted.
