Fine temperature control metal powder coating mixing equipment

Abstract

The invention discloses precise temperature control metal powder coating mixing equipment. The fine temperature control metal powder coating mixing equipment comprises a rack, a feeding hopper arranged on the rack, a hot mixing cylinder mounted in an inner cavity of the rack, a cold mixing cylinder, a cooling device and a driving device, a stirring device is arranged in the hot mixing cylinder, one end of the stirring device is fixed on the rack, and the other end of the stirring device extends into the hot mixing cylinder; and the hot mixing cylinder is provided with a cooling cavity, and the cooling device is connected with the cooling cavity through a cooling circulating pipe to form a sectional type cooling circulating system. According to the invention, four circulating cooling water paths in a four-inlet four-outlet sectional type are arranged on the hot mixing cylinder, and cooling is carried out in a sectional manner, so that the cooling speed is high, and the cooling effect is good; meanwhile, the temperature in the hot mixing cylinder is monitored in real time, and the temperature control precision is high; in addition, the whole structure of the rack is of an n-shaped structure, the hot mixing cylinder and the cold mixing cylinder are arranged in an inner cavity of the rack, an air filter element is arranged in the back of the rack and matched with an induced draft fan, dust can be wrapped, pollution caused by leakage is not prone to occurring, layout is scientific and reasonable, and production is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of powder mixing, in particular to a precise temperature-controlled metal powder paint mixing equipment. Background technique [0002] At present, the mixing technology of metal powder coatings is composed of dry mixing method and heat treatment method. Put the powder coating base powder into the high-speed mixer with a temperature-controlled jacket, and use the high-speed rotation of the machine to cause friction in a short time due to the difference in motion speed between the stirring paddle and the mixing material. Elevation, the existing mixer is equipped with a main shaft in the mixing device, and there are multiple sets of stirring blades installed on the main shaft. There are interconnected circulating water channels on the stirring blades and the main shaft. The circulating water pipe is connected to the end of the main shaft through a rotary joint. When the stirring blade rotates, the frictional h...

Problems solved by technology

During this process of over-stirring and heating up, temperature control and dust treatment are important parameters to achieve a better mixing effect. If the temperature is too high, the degree of melting of the plastic powder particles will be increased, forming agglomerates, and the expected product cannot be obtained. If the temperature is too low, the surface of the plastic powder will not be melted enough to fully and firmly adhere to the pigment particles, resulting in uneven color and poor mixing effect; at the same time, if the temperature and dust are not well controlled, it is prone to shutdown, and it cannot work continuously for 24 hours, which will affect the work. efficiency, and cause secondary pollution
