Description

A sewage discharge device for tobacco vacuum pump buffer tank

technical field

The utility model relates to the field of cleaning and maintenance of buffer tanks of tobacco vacuum pumps, in particular to a blowdown device for the buffer tanks of tobacco vacuum pumps.

Background technique

The tobacco vacuum pump system serves the crimping and packaging equipment. Since the crimping and packaging equipment produces a lot of soot and dust during normal production, part of the soot and dust is sucked into the buffer tank along with the vacuum pipeline. Therefore, the cleaning and maintenance of the vacuum pump buffer tank is an indispensable link in the process of vacuum pump equipment maintenance, which directly affects the supply guarantee capacity of the production workshop equipment. Since multiple vacuum pump units share one buffer tank, combined with the tight task of tobacco production, the cleaning and maintenance of the buffer tank is usually arranged at the end of the end of production at the end of the month: the vacuum pump buffer tank is originally equipped with a DN50 sewage pipe, and the tap water valve is opened every time the buffer tank is cleaned. Because the sewage pipe is too small, the soot scale in the buffer tank seriously blocks the sewage pipe, and it cannot be cleaned automatically at all. The maintenance personnel had to dismantle the manhole of the buffer tank to enter the buffer tank, and use the method of "shovel + plastic bucket" to clean out the soot. Due to the limited space in the buffer tank, the internal odor is large, the labor intensity is high, and the outflow of soot and sludge causes secondary pollution on the ground, which not only affects on-site management and equipment management, but more importantly affects the health of maintenance personnel.
