There is an air vent at the top of the resin capsule cage, a liquid outlet at the bottom, a sealed O-ring in the air vent, a circular flange at the lower part of the air vent, and a flange with an inner diameter smaller than the outer diameter , The ball is made of a material that is lighter than water. The filter consists of a connecting part, an end cap and a filtration material. The connection is connected to the liquid outlet of the cage, the pores are distributed on the surface of the end cap, and the filtration film is welded on the surface of the end cap. The filtration membrane has hydrophobic and oil barrier properties and the pore size of the filtration membrane is smaller than the pore size of the filter filtration material. The purpose is to discharge the air in the filter through the pores of the end cap and the filtration membrane into the space between the inside of the cage and the outside of the filter. Finally, the air between the inside of the cartridge and the outside of the filter passes through the air vent And discharged to the outside.
In this process, the filtration membrane layer welded to the end cap has a hydrophobic and oil-blocking characteristic, and the filtrate in the filter is not mixed with the raw liquid between the resin capsule cage to the outside of the filter, and the raw liquid in the resin capsule cage is filtered through the filtration layer, Liquid flows into the filter. The nut in this design is directly connected to the interior of the air vent.
Description
The present invention relates to a filter having a vent structure.
The present invention relates to a filter used for filtering a lithium battery paste solution, an aqueous solution, a corrosive solvent, and an etching solution. The filter of this invention installs a liquid inlet and an air vent in an external resin capsule cage. Among them, the air vent is installed on the upper part of the resin capsule cage so that the air inside the resin capsule cage is discharged to the outside through the upper air vent at the same time as the liquid is injected from the lower entrance.
Under normal conditions, when the air is soon to be discharged, the nuts installed in the upper air vents are closed to prevent leakage of the internal liquid. However, since it is not possible to control the timing at which the internal air is completely exhausted, wait until the air is completely exhausted, and then insert the nut, and the internal liquid will leak out from the air vent. Especially, corrosive liquids cause environmental pollution.
Accordingly, improvement of the conventional exhaust method of the filter and prevention of liquid leakage are problems to be solved in the industry.
The present invention provides a vented filter and includes a hollow resin cage cage, a filter installed within the resin cage cage, and a nut fastened to the air vent above the resin cage cage.
Among them:
An air vent is provided above the resin capsule cage, a liquid outlet is provided in a lower portion of the resin capsule cage, an O-ring sealed in the upper air vent is provided, and an O-ring and a floating ball is installed in the empty space.
The filter consists of a connecting part, an end cap and a filtration material.
The connection of the filter is connected to the liquid outlet at the lower end of the resin capsule cage and the pores are distributed on the surface of the upper end cap of the filter, and the filter membrane is welded thereon.
Firstly, there is a circular flange on the edge of the empty space of the air vent, and the inner diameter of the circular flange is made smaller than the outer diameter of the floating ball.
First, the floating ball is made of a material that is lighter than water.
Firstly, the filtration membrane has hydrophobic and oil-blocking ability, and the pore size of the filtration membrane is smaller than the pore size of the filtration material installed inside the resin capsule cage.
First, connect the nut to the upper air vent on the resin capsule cage.
As described above, the present invention is composed of a resin capsule cage, a filter, and a nut as a filter having a specific vent structure.
An air vent is provided above the resin capsule cage, a liquid inlet is provided in a lower portion of the resin capsule cage, an O-ring is installed to seal the inside of the air vent, and a floating ball is installed inside the hollow space , A circular flange is provided at the edge of the empty space formed in the air vent, the inner diameter of the circular flange is made smaller than the outer diameter of the floating ball, and the floating ball is made of a material that is lighter than water.
The objective is to close the air vents when the liquid reaches the top of the resin capsule cage through the inlet, pushing the floating ball toward the O-ring located above the groove.
The filter installed inside the resin capsule cage is composed of a connecting part, an end cap and a filtering material.
The connection portion of the filter is connected to the liquid outlet of the resin capsule cage, the pores are distributed on the surface of the end cap, and the filtration film is welded on the surface of the end cap.
The filtration membrane has hydrophobic and oil barrier properties and its pore size is smaller than the pore size of the internal filter filtration material.
The purpose is to exhaust the air inside the filter through the pores of the filter end cap and the filter membrane between the inside of the resin capsule cage and the outer space of the filter and finally the air between the resin capsule cage and the filter is discharged to the outside .
In this process, the filtration membrane layer welded to the end cap has hydrophobic and oil-blocking characteristics. The filtrate in the filter is not mixed with the undiluted solution between the filter and the resin capsule cage, and the level of the liquid level between the resin capsule cage and the filter When higher, the undiluted solution is filtered through the filter layer welded to the end cap portion, and the filtered liquid flows into the filter.
The nut in this design is directly connected to the interior of the air vent.
The purpose is to prevent liquid leakage by manually turning the nut when the floating ball fails to close the air vent because it does not reach the O-ring.
The present invention relates to a filter of a vent structure and realizes the purpose of automatic exhaust and liquid leakage prevention.
