Simple and convenient storage type ventilation device for coating

Abstract

The invention discloses a simple and convenient storage type ventilation device for coating. The simple and convenient storage type ventilation device comprises a ventilating pipe and a dust collecting hopper, wherein an air inlet is formed in the left end of the ventilating pipe, an air outlet is formed in the right end of the ventilating pipe, and a support is fixed inside the ventilating pipe at the same time; a first bevel gear box is installed on the upper side of the support, the right end of the first bevel gear box is connected with a first fan blade through a first rotating shaft, thedust collecting hopper is arranged on the lower side of the middle of the ventilating pipe, and a dust collecting bag is arranged on the lower side of the dust collecting hopper; and a dust blockingplate is fixed above the dust collecting hopper, the right end of the dust blocking plate is fixed with the inner wall of the ventilating pipe, a bag type filter screen is installed on the right sideof the ventilating pipe, and bearings are arranged at the two ends of a rod outer shell. The simple storage type ventilation device for the coating facilitates air circulation inside a coating chamber, impurities in the coating chamber can be filtered, the ventilation device adopts clean energy wind energy as power, so that energy is saved, and noise is avoided.

Description

technical field [0001] The invention relates to the technical field of painting, in particular to a simple and retractable ventilation device for painting. Background technique [0002] The paint spraying room refers to the room equipped with painting equipment for painting operations. The spraying room includes a powder spraying room, a paint dipping room, a curtain coating room and a ventilation room. The purpose and function of the ventilation room are mainly dust prevention and ventilation. . [0003] The existing ventilation device has a relatively simple structure, and the dust directly filtered by the filter is often more, and the filtered dust is not easy to store, resulting in frequent replacement of the filter. At the same time, the ventilation device is generally noisy and affects the surrounding environment. Generally installed in open areas, the existing ventilation devices do not use clean energy wind energy for ventilation, resulting in waste of resources. In...
