Problems solved by technology

[0002] Existing polymer powders, especially polymer material powders, need to be cooled in advance in some crushing or processing, especially before the material powder enters the crusher, in order to make the crusher work according to the rated power, a uniform speed is required. Feed the material powder into the crusher; the existing material powder is directly fed into the crusher from the screw extruder, the feeding is uneven, the damage to the crusher is large, and the cooling consumes a lot of liquid nitrogen. The prior art There is an urgent need for a powder cooling continuous feeding mechanism with uniform feeding and low energy consumption

Abstract

The invention discloses a powder cooling continuous feeding mechanism. The powder cooling continuous feeding mechanism comprises a feeding hopper and a screw extruder connected with the feeding hopper, wherein a continuous feeding mechanism is arranged on an discharging opening of the screw extruder, the continuous feeding mechanism comprises a material storage tank body, and a tank body material-inputting opening is formed in the top of the material storage tank body; and a tank body feeding opening is formed in the bottom of the material storage tank body, and a gate valve is installed on the tank body feeding opening. According to the scheme, material powder discharged from the screw extruder can be stored in the material storage tank body first, and then the material powder can be fedinto a crusher at a uniform speed through the control of the gate valve, so that continuous operation is achieved, and rated power operation of the crusher is achieved at the same time.

Description

technical field [0001] The invention relates to a powder cooling continuous feeding mechanism. Background technique [0002] Existing polymer powders, especially polymer material powders, need to be cooled in advance in some crushing or processing, especially before the material powder enters the crusher, in order to make the crusher work according to the rated power, a uniform speed is required. Feed the material powder into the crusher; the existing material powder is directly fed into the crusher from the screw extruder, the feeding is uneven, the damage to the crusher is large, and the cooling consumes a lot of liquid nitrogen. The prior art There is an urgent need for a powder cooling continuous feeding mechanism with uniform feeding and low energy consumption. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a powder cooling continuous feeding mechanism with uniform feeding and low energy...
