Plastic particle mixing cooler

Abstract

The invention discloses a plastic particle mixing cooler and relates to the field of plastic processing. The plastic particle mixing cooler comprises a material storage barrel, a material return barrel and a feeding pipe, wherein a discharge pipe and a material return pipe are arranged at the lower end of the material storage barrel, the discharge pipe and the material return pipe are respectively provided with a discharge valve I and a discharge valve II, the material return pipe communicates with the material return barrel, and a feeding hole is formed in the material return barrel; the material storage barrel comprises a barrel body made from non-woven fabric and a support frame for tensioning the barrel body, a dust collection barrel is arranged outside the material storage barrel, an electrostatic precipitator is arranged between the material storage barrel and the dust collection barrel, and vent holes are formed in the lower end of the dust collection barrel; and the feeding pipe comprises a main pipe and a branch pipe communicating with the main pipe, one end of the main pipe communicates with the upper end of the material storage barrel, the other end of the main pipe is connected with an air blower, and the branch pipe communicates with the material return barrel. According to the invention, due to arrangement of the electrostatic precipitator and change of the mounting position of the air blower, discharged ash is greatly reduced, and the circulating mixing effect is improved.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a cooling machine for mixing plastic particles. Background technique [0002] Engineering plastics have been widely used in various fields due to their unique properties, and the requirements for materials are more stringent, such as black spots, color and performance consistency, so the scientific design of product mixer structure has become one of the important factors to ensure product quality one. There are basically two types of mixers at present, one is a mixer without paddles; the other is a storage tank with paddles. The former has the advantages of simple structure, easy cleaning, no dead angle, and can better solve the problem of black spots in the product cooling and packaging process. Its disadvantage is that the mixer cannot mix in a circular manner, does not have the actual mixing function, and cannot guarantee the color of the product. Consistency and performanc...

Problems solved by technology

The former has the advantages of simple structure, easy cleaning, no dead angle, and can better solve the problem of black spots in the product cooling and packaging process. Its disadvantage is that the mixer cannot mix in a circular manner, does not have the actual mixing function, and cannot guarantee the color of the product. Consistency with performance; the advantage of the latter is that it can better solve product performance and color consistency, and its disadvantage is that the equipment is more complicated, it is not easy to clean, and it is difficult to avoid black spots and miscellaneous material pollution

[0003] In order to enable the mixing machine without stirring paddles to achieve cyclic mixing, the Chinese Patent Publication No. CN203449492U discloses an easy-to-clean and automatic cooling mixing machine, which mainly includes a conical storage tank at the bottom. A discharge pipe is provided at the bottom of the feed pipe, a discharge valve is provided on the discharge pipe, a feed pipe is connected to the storage tank, a hopper is connected to the bottom of the feed pipe, and a screening machine and a blower are also connected to the hopper; A return pipe is provided between the bottom of the storage tank and the receiving hopper, and a material discharge valve is provided on the return pipe; an exhaust port is provided at the top of the storage tank; the material is blown by a blower It circulates between the storage tank, the return pipe and the feed pipe, but because the exhaust port is set on the top of the storage pipe, a lot of dust will be raised when the air flow is discharged; in addition, when the blower of the mixer is blowing, Air flow to the storage pipe is generated in both the return pipe and the feed pipe, so the circulation effect of the material is not good
