Partial section closure device with positive-negative air-pressure double channels

Abstract

The invention discloses a partial section closure device with positive-negative air-pressure double channels. The partial section closure device comprises an air suction tank, an air exhaust pipe, anair supply barrel and an adjustable rotary cover. A gas inlet connector is arranged on the air suction tank, the air exhaust pipe comprises a gas exhaust pipe and an air draft barrel, the air supply barrel and the air draft barrel are of annular nested threaded connection structures, the air supply barrel is connected with the adjustable rotary cover in a threaded manner, and gaps which are reserved between the air draft barrel and the adjustable rotary cover and are used for blowing out gas can be adjusted by the aid of the adjustable rotary cover. The partial section closure device has the advantages that water vapor in external air can be effectively isolated in filling procedures, chemical reaction on chemical raw materials can be assuredly prevented in the filling procedures, accordingly, economic loss and other harmful effects due to the chemical reaction can be effectively prevented, and the partial section closure device has great significance for chemical material manufacturers.

Description

technical field [0001] The invention belongs to the field of high-risk, high-pollution, and high-intensity chemical industry filling equipment, and specifically relates to a partial section sealing device with positive and negative wind pressure dual channels. Background technique [0002] Due to the special physical and chemical properties of many chemical raw materials, they will react chemically with water vapor in the air, such as ethyl acrylate solidifies with water, etc. The existing chemical filling equipment solves this problem by filling in a closed filling room, filling the filling room with dry air or inert gas in order to form a slight positive pressure in the filling room. In order to prevent the air containing water vapor from entering the filling room and affecting the normal filling of materials, see the attached figure 1 After the conveying roller table 5 is arranged, it passes through the closed filling room 1, and the container 3 containing the material i...

AI Technical Summary

Problems solved by technology

[0003] In order to effectively solve the problem that during the filling process of the filling equipment, a large amount of air containing water vapor enters the filling room to react with the materials and deteriorate, the invention provides a partial section sealing device with positive and negative air pressure dual channels , effectively isolate the water vapor in the outside air during the filling process, ensure that chemical raw materials do not undergo chemical reactions during the filling process, and effectively avoid economic losses and other adverse effects caused by it, which is of great significance to chemical material manufacturers
