Description

Benzene storage tank drainage device Technical Field The utility model relates to the technical field of benzene storage tanks, in particular to a benzene storage tank drainage device. Background Benzene storage tanks are specialized containers for storing benzene, a flammable, explosive and toxic liquid aromatic hydrocarbon, which are designed and operated to strictly follow safety regulations to prevent leakage, fire or explosion accidents. Through searching, patent number CN217101343U discloses a benzene storage tank drainage device, through establishing ultrasonic sensor for judge whether medium in the communicating pipe is water, realize automatic drainage through interlocking control's electric valve, set up and stand and the further separation benzene of coalescer and water, reduce the aquatic and contain benzene volume, be favorable to the further processing of water, improve the rate of recovery of benzene product. The above patent content is to judge whether the communicating pipe is water or not through the arrangement of the ultrasonic sensor and separate benzene and water through the collector, however, the device can realize the drainage of the benzene storage tank, but the device has the advantages of more electric control structures of the whole structure, high cost and large occupied space, and is not suitable for the use of a small benzene storage tank. Disclosure of utility model The utility model aims to provide a benzene storage tank drainage device to solve the problems in the background technology. In order to solve the technical problems, the utility model adopts the following technical scheme: The benzene storage tank drainage device comprises a lifting frame, wherein a storage unit is arranged on the top surface of the lifting frame, and the output end of the storage unit is fixedly connected with a liquid separation unit; The liquid separation unit comprises a support, the support is fixedly connected to the bottom surface of the storage unit, a liquid separation bin is fixedly connected to the inside of the support, and a liquid inlet funnel is fixedly connected to the input end of the liquid separation bin.
