Proportioning metering and adding device for plasticizer

Abstract

The invention discloses a proportioning metering and adding device for a plasticizer. The proportioning metering and adding device comprises a cylinder body, the lower end of the cylinder body is hermetically arranged, a left supporting plate and a right supporting plate are fixed at the left end and the right end of the outer side surface of the cylinder body respectively, a PLC is fixed on the upper surface of the right supporting plate, a stepping motor is fixed on the upper surface of the left supporting plate through a fixing frame, an output shaft of the stepping motor and the lower endof a screw are connected through a coupler, the screw is in threaded connection with a screw hole in a push plate, the output shaft of the stepping motor drives the screw to rotate, the screw drives the push plate to move up and down, and the push plate drives a transverse plate to move up and down through a vertical plate, so that the plasticizer is continuously extracted and discharged. The operation is simple, the plasticizer cannot leak out, and the safety is high; when the plasticizer in the cylinder body contains bubbles, an air valve is opened to enable an external vacuum pump to vacuumize the inside of the cylinder body, the plasticizer is heated through an electric heating plate to reduce the viscosity of the plasticizer, then the bubbles are accelerated to be separated, and the adding precision of the plasticizer is guaranteed.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a batching metering and adding device for plasticizers. Background technique [0002] Plasticizer is a commonly used auxiliary agent, which is often used in the molding and preparation of high polymers such as rubber, plastics, and coatings. In the actual operation process, the operator needs to extract the corresponding plasticizer into the iron bucket for weighing, and then add the weighed plasticizer into the mixture for mixing. During the use of plasticizers, not only is the operation complicated and extremely inaccurate, but it may also cause leakage of plasticizers during the process of moving and dumping, which is very unsafe; because plasticizers themselves are generally relatively viscous, sometimes when transporting Vibration causes the plasticizer to contain air bubbles, which affects the accuracy of adding.
