Description

Technical Field

[0001] The utility model relates to the technical field of liquid chlorine filling, in particular to an impurity removal device for liquid chlorine filling. Background Art

[0002] Liquid chlorine, i.e. liquid chlorine, is a yellow-green liquid, highly toxic. It vaporizes into gas under normal pressure, which can cause severe poisoning if inhaled. It is highly irritating and corrosive. It burns and explodes when mixed with other flammable gases under sunlight. It is active and can react with most single substances (or compounds). Liquid chlorine is generally used after being vaporized. It has a wide range of uses. It is a strong oxidant and is used for bleaching in the textile and papermaking industries, purification and disinfection of tap water, refining of magnesium and other metals, and preparation of various chlorine-containing compounds such as pesticides, detergents, plastics, rubber, and medicines. In chemical production, polyethylene and liquid chlorine are synthesized into polyvinyl chloride and chlorinated polyethylene. It is widely used in industries such as papermaking, textiles, pesticides, organic synthesis, metal smelting, chemical raw materials, and domestic water disinfection.

[0003] During the production of liquid chlorine, certain impurities will exist in the liquid chlorine. Therefore, the liquid chlorine needs to be filtered and impurities removed before filling, and then filled. It is not possible to filter and impurities directly during filling, which affects the efficiency of liquid chlorine filling. Therefore, the utility model provides an impurity removal device for liquid chlorine filling. Utility Model Content

[0006] A third mounting tube is arranged at the upper end of the filling tube, and the lower end of the second filter tube is inserted into the third mounting tube. Sealing rings are arranged in the first mounting tube, the second mounting tube and the third mounting tube, and the sealing rings are in contact with the first filter tube and the second filter tube respectively.

[0007] Preferably, an annular support plate is disposed on the inner wall of the first filter tube and the second filter tube, and the ceramic filter layer and the polypropylene filter layer are both located at the upper end of the annular support plate.

[0008] Preferably, a hose is provided at the lower end of the filling tube, and a filling head is installed at the end of the hose.

[0009] Preferably, the inner walls of the connecting tube and the first filter tube are both equipped with symmetrically distributed fixing rods, and positioning plates are installed at the ends of the fixing rods. The lower end of the positioning plate in the connecting tube contacts the upper end of the ceramic filter layer, and the lower end of the positioning plate in the first filter tube contacts the upper end of the polypropylene filter layer.

[0010] Preferably, a first mounting plate is symmetrically installed on the side end of the connecting pipe, a second mounting plate is symmetrically installed on the side end of the third mounting pipe, a hydraulic device is installed on the lower end of the first mounting plate, and the end of the hydraulic rod of the hydraulic device is connected to the upper end of the second mounting plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. When filling, liquid chlorine enters from the beginning of the connecting pipe, passes through the first filter tube and the second filter tube, and can be filtered and impurities removed by the ceramic filter layer and the polypropylene filter layer. The impurity-removed liquid chlorine enters the filling pipe, and the liquid chlorine is discharged from the filling pipe into the hose, and is filled into the container from the filling head, thereby completing the filling of liquid chlorine. Impurities can be removed during filling, which can improve the filling efficiency of liquid chlorine.

[0013] 2. When the ceramic filter layer and the polypropylene filter layer need to be cleaned or replaced, the hydraulic equipment works to extend the hydraulic rod, which can move the filling tube away from the connecting tube, thereby loosening the fixation of the first filter tube and the second filter tube, and the first filter tube and the second filter tube can be easily disassembled and removed, so as to clean or replace the ceramic filter layer and the polypropylene filter layer, and facilitate the liquid chlorine filling and impurity removal work.
