Rotary switch type dust elimination powder coating bagging device

Abstract

The present invention discloses a drum switched type dust elimination powder coating bagging device. The interior of a drum switcher is a cylindrical airtight cavity. A stepping motor is arranged on the upper portion of the cavity and connected with a shaft rod entering the cavity along the axis of the cavity. A longitudinal partition board is connected to the shaft rod. The periphery of the partition board is in clearance fit with the inner wall of the cavity. An upper annular support and a lower annular support which are fixedly connected with the partition board are arranged in the cavity. A cylindrical filter net connected with the partition board is connected between the upper annular support and the lower annular support. A gap is reserved between the filter net and the inner wall of the cavity. A dust air inlet and a dust air outlet are formed in the cavity and distributed symmetrically on the two sides of the partition board. A clean air outlet is formed between the partition board of the bottom of the cavity and the lower annular support and located on one side of the dust air inlet. A clean air inlet is formed between the partition board of the bottom of the cavity and the lower annular support and located on one side of the dust air outlet. The drum switched type dust elimination powder coating bagging device can conduct reciprocating dust removal, keep suction force stable all the time and avoid powder leakage and dust flying, and is simple in structure, easy to implement and suitable for application and popularization.

Description

technical field [0001] The invention relates to a powder paint processing equipment, in particular to a rotary-drum switchable dust-elimination powder paint bagging device. Background technique [0002] China is the manufacturing center of the world, and it needs to consume a large amount of coatings every year. Most of the existing coatings are prepared liquid types. The cost of transportation must be high in barrels. Restricted by factors, powder coatings have developed rapidly in recent years. It has the advantages of low bagging cost, small space occupied by storage and transportation, small proportion compared with unit dosage, no volume dilution and no climate influence, avoiding losses due to freezing, and further reducing Storage and transportation costs in winter, with the increase in production of powder coatings, its manufacturing equipment has not made major technological progress, and there are still some deficiencies, such as in terms of dust leakage, mills and...

Problems solved by technology

[0002] China is the manufacturing center of the world, and it needs to consume a large amount of coatings every year. Most of the existing coatings are prepared liquid types. The cost of transportation must be high in barrels. Restricted by factors, powder coatings have developed rapidly in recent years. It has the advantages of low bagging cost, small space occupied by storage and transportation, small proportion compared with unit dosage, no volume dilution and no climate influence, avoiding losses due to freezing, and further reducing Storage and transportation costs in winter, with the increase in production of powder coatings, its manufacturing equipment has not made major technological progress, and there are still some deficiencies, such as in terms of dust leakage, mills and silos are generally closed during production There is very little leakage of dust in the type circulation, and the powder made by the mill machine must be bagged before leaving the factory after entering the silo. When bagging, there is a lot of air inside the bag, and the seal with the outlet is not good. When the powder coating falls, it will be impacted. A large amount of dust is generated in the bag, and the air in the bag is squeezed out of the bag mouth with the filling of the powder coating in the bag, and the dust also leaks out with the air flow, causing harm to the production environment, not only affecting the health of the staff, but also easily causing catastrophic dust storms Accidents, this problem still needs to be solved to promote the development of powder coating industry
