Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco cleaning agent filling, in particular to an exhaust mechanism of cleaning agent filling equipment. Background Art
[0002] In the actual production process of the tobacco industry, cleaning agents are needed to regularly and effectively clean the storage tanks and pipeline systems used for production, completely eliminate the residual sugar materials in the production equipment of the tobacco industry, and avoid quality risks and accidents caused by odor and cross-flavor between products. Cleaning agents include two categories: inorganic cleaning agents and organic cleaning agents. The difference is simply that organic cleaning agents are cleaning agents made of carbon-containing compounds, and inorganic cleaning agents are cleaning agents made of carbon-free compounds. There are also many ways to classify cleaning agents, which are usually divided into three categories: aqueous, semi-aqueous, and non-aqueous cleaning agents. The cleaning agent needs to be filled after production is completed, so filling equipment is needed.

When the equipment is actually used, the cleaning agent in the storage tank is transported to the nozzle through the delivery hose and then into the filling barrel. However, due to the lack of exhaust function during the flow of the cleaning agent in the delivery hose, the mixed gas enters the filling barrel together with the cleaning agent during weighing after filling, which leads to insufficient weight of the cleaning agent filled into the filling barrel, that is, the actual filling amount is too small, resulting in false weighing values, losing the true weighing accuracy, affecting the actual metering requirements of filling, and in order to reduce the weighing error of the cleaning agent caused by the gas content, the weighing setting value of the filling equipment needs to be set larger than the standard value, thereby increasing the production cost. In view of the above problems, it is necessary to improve the existing cleaning agent filling equipment. Summary of the invention
