Description

Continuous Filter Housing without Air Drain, Fluid Drain and Connection Piping {Filter Housing Unit}

In order to produce LCD, PDP, OLED, and PCB products, various processes such as cleaning, etching, and peeling are required, and most of the facilities for processing these processes use processing liquids.

The treatment liquid is used in a facility by installing a reservoir for storing the treatment liquid inside the equipment and spraying the object with a pump. The treatment liquid once supplied to the reservoir can handle a predetermined time or a predetermined number of objects. Continue to cycle until used. That is, the sprayed treatment liquid is recovered to the storage tank and the recovered treatment liquid is sprayed again. Since the processing liquid used in this circulation is contaminated with time, it is necessary to remove the contaminants using a filter before spraying the processing liquid pressurized by the pump.

The installed filter cartridge is used to replace the filter cartridge when the end of life due to use for a certain time or contaminants, and the filter housing is also adopted to replace the cartridge essentially.

Generally, the filter consists of a filter housing and a cartridge. The filter housing may be used repeatedly as a part in which the cartridge is mounted. The filter cartridge is a part in which contaminants contained in the flowing fluid are filtered.

As shown in FIG. 8, the conventional filter housing 50 is composed of a housing-head 51, a housing-cup 53, and a nut 52. The housing-head 51 has a fluid supply port 55 and a fluid discharge port 56 and a cartridge is connected thereto. The cartridge is inside the housing-cup 53. The housing cup 53 is a portion surrounding the cartridge. When the cartridge is replaced, the housing cup 53 must be separated from the housing head 51 to secure a space for the operator to remove the cartridge. FIG. 8 schematically shows the distance G at which the housing-cup 53 is separated from the housing-head 51, and the housing-cup 53-1 is in a separated state.

When applied in actual equipment, only one filter housing may be used but generally two or more are installed. When a plurality of filter housings are installed, connection pipes may be installed as shown in FIG. 5 to simultaneously use the filter housings. As shown in the figure, when connecting piping is used, the required space is rapidly increased depending on the number of filter housings to be connected, and various pipe materials are consumed to increase the cost of manufacturing the equipment.

As described above, the conventional cartridge replaceable filter housing 50 must remove the housing-cup as shown in FIG. 8 when replacing the cartridge, so that the cartridge can be separated and replaced from the housing-head.

That is, in order for the operator to detach the cartridge from the housing-head 51, the housing-cup 53 must be moved upward by a gap G at which the cartridge can be replaced.

Due to these factors, in order to separate the housing-cup, there must be no obstacle in a certain space in the direction in which the filter housing is installed. Of course, if the filter housing is installed upside down there should be no obstruction in the downward direction.

In addition, in the case of piping in order to connect the filter housings in parallel, a separate space and material for the connection of the pipes are required, which acts as a factor that increases the cost and limits the design of the equipment.

In addition, as shown in FIG. 6, an upper portion of the filter housing, which is essential for using a conventional filter housing, requires an air discharge pipe, and a lower portion of the filter housing removes the fluid inside the filter housing when the filter cartridge is replaced. DRAIN piping is needed. These air discharge and drain pipes are required for each filter housing, which is cumbersome to manufacture and increases the cost of manufacturing equipment.

Thus, the conventional filter housing has a lot of difficulties in the installation and use of space constraints and the design and manufacture of the equipment, even after the equipment is installed in the field has a difficulty for the user to replace the cartridge.
