Pneumatic liquid material conveying device

Abstract

The invention discloses a pneumatic liquid device for conveying chemical materials, which comprises a pump body and a discharge pipe. The pump body is a cavity equipped with an air inlet and an air outlet, with the air inlet connected to an air inlet valve through a pipeline, and the pump body is provided with a circular hole. A locking screw cap able to be in threaded connection with the mouth of a liquid material bucket is connected to the air outlet end. The discharge pipe passes through the circular hole on the pump body and the locking screw cap. The cavity of the pump body is communicated with the cap cavity of the locking screw cap. The discharge pipe is provided with a discharge valve. From the air inlet valve and along the air inlet of the pump body, the cavity, the air outlet, the cap cavity of the locking screw cap, as well as the inner cavity of the liquid material bucket, an airtight and sealed airflow channel can be formed. The pneumatic liquid device for conveying chemical materials of the invention has the advantages of simple structure, easy operation, high extraction efficiency, ability to draw all materials out of a material bucket bottom, low cost, safety and convenience, as well as easy cleaning.

Description

technical field [0001] The invention relates to the technical field of equipment for transporting chemical raw materials, in particular to a pneumatic liquid device for transporting chemical raw materials. Background technique [0002] In today's chemical industry, many raw materials or intermediate substances for the production of chemical products are liquid. Due to the large production volume, the liquid materials are generally packed in larger barrels. The following two methods are generally used to take out the materials in the barrel. : 1. Manual dumping. Manual dumping of materials is cumbersome, laborious, and inefficient, and some raw materials are corrosive. If they leak to the outside or the body of the staff, it will cause environmental pollution or personal injury; 2. Use a conventional air pump to extract Liquid, this method has the following disadvantages: 1. The equipment structure is complex, and requires rated power, and the operation is inconvenient; 2. Th...
