Anti-blocking device of powder-liquid mixing pump

Abstract

The invention relates to a powder-liquid mixing pump, in particular to an anti-blocking device of the powder-liquid mixing pump. The anti-blocking device comprises a pipe fitting communicating with apowder inlet and a pump cavity of the powder-liquid mixing pump, and a wiper plug assembly is arranged in the pipe fitting and driven to move by a driving mechanism arranged on the pipe fitting. The anti-blocking device adopts a piston propelling form and a spiral conveying form to conduct anti-blockage dredging of the powder-liquid mixing pump, wherein a hand-cranking lead screw of the piston propelling form has good rigidity, transmission axial force of the lead screw is large, and the anti-blocking device is suitable for powder with the large proportion and is convenient to mount and maintain, and does not need to be externally connected with wires and air pipes; the response speed of the piston propelling form of air cylinder driving and the like is high, adaptability to the working environment is good, the anti-blocking device can be connected with an electromagnetic valve, and a PLC control system is connected into the anti-blocking device to realize automatic control; and the spiral conveying form is simple in structure, maintenance is easy, the feeding amount can be freely controlled, and the PLC control system can be connected into the anti-blocking device to realize automatic control.

Description

technical field [0001] The invention relates to a powder-liquid mixing pump, in particular to an anti-blocking device for a powder-liquid mixing pump. Background technique [0002] With the development of powder processing equipment, the types of powder-liquid mixing equipment are showing a trend of diversification and functional integration. Among them, powder-liquid mixing equipment that integrates powder-liquid suction, mixing, and dispersion is more and more widely used. Different temperature, humidity and solid content will affect the effect of powder-liquid mixing. Therefore, the powder-liquid mixing equipment is prone to blockage. When material blocking occurs, the existing technology generally uses manual dredging, which adds unnecessary labor costs to production and affects production efficiency. Contents of the invention [0003] In view of the above problems, the present invention provides a powder-liquid mixing pump anti-blocking device with simple structure ...
