Plastic powder spraying room with a cyclone recycling and filtering function for coating

Abstract

The invention discloses a plastic powder spraying room with a cyclone recycling and filtering function for coating. The plastic powder spraying room comprises a plastic powder spraying system and a large cyclone recycling system, wherein the plastic powder spraying system comprises a powder spraying device and a powder room body; the powder spraying device comprises a powder spraying cylinder and spray gun mechanisms connected with the powder spraying cylinder; the powder room body is of a plastic structure and is opened on the left side and the right side, and a side plate is arranged on each of the front side and the rear side of the powder room body; each of the spray gun mechanisms is arranged on the outer side of the corresponding side plate; a plurality of vertical through holes allowing spray guns to be embedded in are formed in each of the side plates; a left stopping block and a right stopping block which are clung to each other are arranged in each of the through holes; a plurality of horizontal bottom plates are arranged at the bottom in the powder room body; the bottom plates arranged on the two sides are turnover bottom plates; a collecting barrel is arranged below the bottom plates; the large cyclone recycling system comprises a large cyclone collecting device and a filtering device. The plastic powder spraying room with the cyclone recycling and filtering function for coating has the advantages that the design is reasonable, the powder recycling rate is greatly improved, the cost is reduced, and the degree of contamination caused by powder to the air and operators is reduced.

Description

[0001] Technical field: [0002] The invention relates to powder-spraying equipment, in particular to a plastic powder-spraying room for cyclone recovery and filtration for painting. [0003] Background technique: [0004] Powder coating is a new process in surface coating technology. It is a coating process that coats in powder form and forms a coating film. Due to the characteristics of high labor intensity and high mechanical strength of the coating film, the existing powder spraying booths for painting have the following disadvantages: 1. The existing powder spraying booths are made of metal, and the powder has static electricity during the spraying process, which is easy to adsorb on the metal material. On the side wall of the powder spraying room, it is difficult to clean the powder spraying room, the recycling rate of the powder is low, and the production cost is increased. The airtightness between the powder spraying room and the powder spraying room is poor, and the p...

[0004] Powder coating is a new process in surface coating technology. It is a coating process that coats in powder form and forms a coating film. Due to the characteristics of high labor intensity and high mechanical strength of the coating film, the existing powder spraying booths for painting have the following disadvantages: 1. The existing powder spraying booths are made of metal, and the powder has static electricity during the spraying process, which is easy to adsorb on the metal material. On the side wall of the powder spraying room, it is difficult to clean the powder spraying room, the recycling rate of the powder is low, and the production cost is increased. The airtightness between the powder spraying room and the powder spraying room is poor, and the powder is easily suspended outside the powder spraying room, which will bring certain pollution to the powder spraying operator and cause a certain waste of powder; A powder recovery device is installed outside the room to realize powder recycling, but the powder recovery rate is low, and most of the powder is still discharged from the air, causing certain pollution to the external environment

[0005] Patent No. 200720192350.8 The new type of powder spraying room includes engineering plastic top plate, side plate, end plate and base, which effectively overcomes the shortcomings of difficult cleaning and low powder recycling rate brought by metal powder spraying rooms, but this patent is only a The simple powder spraying room device does not effectively solve the problems of powder recovery and environmental protection

Patent No. 201410116907.4 A fully automatic powder recovery and reuse powder spraying room device, which consists of a frame, a powder spraying device, a powder suction device, a powder shock device, a collection device, and a powder feeding device, wherein the powder spraying device, powder suction device, vibration The powder device, collection device, and powder feeding device are all placed inside the bracket. During the powder spraying process, the workpiece is exposed to the outside for powder spraying, which will cause certain pollution to the operator and the environment. The powder recovery of this patent is collected through the powder vibration device. When a large amount of powder is inhaled, a large amount of powder will block the vibration motor and the bellows, affecting the rapid recovery of the powder, and the recovery effect of the powder is poor, and most of the powder will float into the air to pollute the external environment
