Problems solved by technology

However, this manual control method cannot guarantee accuracy, either the upper layer liquid is extracted due to insufficient insertion depth, or the bottom layer liquid is extracted due to excessive insertion depth, these deficiencies will cause unwanted liquid components to be mixed in the extracted liquid

Embodiment Construction

[0024] Aiming at the problem of layered extraction of layered liquid materials (such as coatings, glues, paints, etc.), the present invention provides a material extraction device, which is used to extract liquids from containers with upper openings, especially liquids that require layers .

[0025] first see attached Figure 1-3 , the liquid material to be extracted is placed in a container 1 (such as a material cylinder, material barrel, material storage box, etc.) with an upper opening. The material pumping device of the present invention mainly includes a material pumping mechanism and a driving mechanism. Wherein, the material pumping mechanism comprises a material extraction pipe 2 and an isolation cover 3, the inlet of the material extraction tube 2 (usually at its end) is located in the isolation cover 3, and the side of the isolation cover 3 is provided with Pumping openings (such as one or more round holes or slotted holes on the side). Wherein, the pumping mechan...

Abstract

The invention discloses a material pumping device for pumping liquid from a vessel with an opening formed in the upper side. The material pumping device comprises a material pumping mechanism and a drive mechanism, wherein the material pumping mechanism is composed of a material pumping pipe and an isolation hood; a feeding hole of the material pumping pipe is formed in the isolation hood; a material pumping opening is formed in the side surface of the isolation hood; and the material pumping mechanism is installed in a suspension manner so as to extend downwards into the vessel and moves up and down driven by the drive mechanism. According to the material pumping device disclosed by the invention, when the material pumping mechanism pumps a material, a liquid material in the vessel can enter the isolation hood approximately in the horizontal direction only, so that the material pumped by the material pumping device is corresponding to a level where the material pumping opening is located, and a material at an upper layer or a lower layer is prevented from being pumped.

Description

technical field [0001] The invention relates to a material pumping device, which is especially suitable for extracting liquids of required layers from layered liquid materials. Background technique [0002] In industrial practice, liquid materials composed of more than two components (such as industrial liquids and colloidal objects) are often used. This type of liquid material often produces stratification, resulting in uneven material composition. Taking paint as an example, the mixed paint often has the problem of floating color that is difficult to solve due to the delamination of the upper layer. When stratification is formed, the upper liquid containing the floating color should generally be avoided, and it is desirable to extract a specific range of liquid below the liquid level. In addition, industry often encounters situations where liquid materials are intentionally stratified and separated. [0003] In the prior art, in order to solve the above demands, the inse...
