Tank connection liquid extracting device and assembly method thereof

Abstract

The invention discloses a tank connection liquid extracting device. As an internal pipe is arranged in a tank body, a liquid extracting pipe and an intake pipe only need to be controlled to move for a shorter path in use so as to communicate with the internal pipe and to realize the air pressure balance, a long pipe is not needed to insert from the upper side of the tank body to the bottom of the tank body, the structure is simpler, the assembly is more convenient, and the production cost is largely reduced; and after the liquid extracting pipe is communicated with the internal pipe, a sealing flange and a lower flange are butted and sealed to realize mutual independence of an intake groove and a liquid extracting hole, and an upper flange and a butting piece are butted and sealed to realize sealing with the external, so that the overall sealing performance is more excellent. An assembly method of the tank connection liquid extracting device is convenient to assemble, and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of liquid pumping, in particular to a liquid pumping device connected to a tank and an assembly method thereof. Background technique [0002] Traditionally, there are two ways to sell wine. The first is to sell wine in bottles, which is to fill a specified volume of wine into a wine bottle, and then sell a bottle of wine as a whole; the second is to sell wine in bulk. When buying wine that does not require the amount of alcohol in catties, it is necessary to weigh the wine on the spot. This often requires the presence of the wine buyer and the wine seller at the same time, and the wine seller weighs the wine according to the amount required by the buyer. In this way, the wine buyer can get the wine of the required weight. With the progress of the society and the development of the economy, people have higher and higher requirements for the quality of life. Automatic wine vending machines have appeared in so...

AI Technical Summary

Problems solved by technology

However, the tank cover generally adopts a plastic cover, a silicone cover or a rubber cover. The bottom of the tank cover is directly in contact with the inner space of the tank body. The alcohol in the tank will volatilize for a long time and thus directly contact with the tank cover. The chemical reaction does not meet the food hygiene and safety standards

And in the prior art, it is necessary to arrange a sealing ring at the bottom joint between the long tube and the tank cover. This sealing structure is not stable enough, and often does not have a good sealing effect, and the sealing ring is generally made of silica gel or rubber. Contact with volatilized alcohol cannot avoid problems affecting the quality of alcohol

Moreover, this method of directly piercing the bottom of the tank with a long tube requires a relatively long stroke of the long tube in the up and down direction, so it is necessary to design a more complicated transmission mechanism and an electrical control mechanism to realize the puncture. The structure is more complicated and the operation is more inconvenient. , the cost is also higher
