Description

TECHNICAL FIELD [0001] The present invention relates to a chemical filter having a filter cap integral type cover,

The present invention relates to a chemical filter, and more particularly, to a cover for a chemical filter, which is integrally provided with a filter cap for opening and closing an upper end portion of a filter cartridge mounted inside a chemical filter.

Generally, a filter is used to filter foreign matters contained in a fluid such as gas or liquid. It is used in water treatment devices such as a water treatment filter water purifier, an ionizer, and a domestic water treatment device such as a bidet. It is installed and used for filtration of process solution in various product manufacturing process.

Such a filter is usually made of a modular structure in which a filter cartridge containing a filter medium is housed inside a housing in the form of a container. The housing of the filter is provided with a water inlet to which a raw water supply pipe is connected and a water outlet to which a process water discharge pipe is connected so that the fluid introduced through the water inlet is filtered through a filter and discharged through a water outlet.

On the other hand, a chemical filter is installed for filtration of a chemical solution for processing in various production processes including a semiconductor manufacturing process.

FIG. 1 shows a conventional chemical filter structure in which a base 20 is attached to a lower part of a cylindrical filter housing 10 and a cover 30 is detachably attached to the upper part of the filter housing 10 And a plurality of filter cartridges 40 are installed in the filter housing 10. The base 20 is provided with an inlet 21 and a filter cartridge 40 through which the fluid inflow is guided to the filter cartridge The fluid introduced through the inlet 21 is discharged through the outlet 22 after the foreign matter is removed in the process of passing through the filter cartridge 40. [

The filter cap 45 is mounted on the upper end of the filter cartridge 40 so that the fluid introduced through the lower inlet 21 flows through the filter cartridge 40 without overflowing to the upper portion of the filter cartridge 40. [ .

However, a plurality of filter cartridges are installed inside the chemical filter. When inspecting the internal of the chemical filter or replacing the filter cartridge, an individual filter cap is assembled to each filter cartridge. There is an inconvenience that the working time is increased during assembly work of the filter cap.

In addition, although the filter cap can be reused, the filter cap is disposed together with the filter cartridge, thereby increasing disposal cost.

The present invention has been proposed in order to solve the above problems in the prior art. The filter cap is integrally formed on the cover body, so that the chemical filter assembly work is more easily performed and the assembling time for assembling the filter cap to the filter cartridge is shortened To be shortened.

In order to achieve the above object, according to the present invention, there is provided a filter device comprising: a base mounted on a lower portion of a cylindrical filter housing; a cover body removably mounted on the upper portion of the filter housing; And a filter cap is integrally provided in the cover to block the upper end of the filter cartridge. The filter cartridge according to any one of claims 1 to 5, wherein the filter cap .

The present invention has the effect that the filter cap assembly on the top of the filter cartridge, which is mounted on the inside of the chemical filter, can be made quicker and easier.

In particular, it is possible to maximize the length of the filter cartridge up to the height of the cover body, thereby showing an advantage of improving the filter effect on the fluid.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a chemical filter structure having a filter cap integrated body according to the first embodiment of the present invention will be described with reference to FIGS. 2 to 4. FIG.

A base 20 is mounted on a lower portion of the cylindrical filter housing 10 and a cover 30 is detachably mounted on the upper portion of the filter housing 10. A plurality of filters A cartridge 40 is constructed and configured such that the base 20 is formed with an outlet 22 through which the fluid that has permeated the inlet 21 and the filter cartridge 40 is discharged to the outside so that the fluid inflow is guided to the filter cartridge.

Particularly, in the cover 30 of the present invention, a filter cap 31 for blocking the upper end of the filter cartridge 40 is integrally provided. The filter cap 31 is provided with an upper surface of the filter cartridge 40, And a sealing agent 32 for sealing is protruded.

In the drawing, reference numeral 41 denotes a hollow portion 41 formed in the filter cartridge 40.

Hereinafter, effects of the use of the chemical filter according to the present invention will be described.

The chemical filter in the present embodiment is configured such that the filter cartridge 40 is permeated in the course of ascending along the hollow portion 41 after the chemical filter is introduced into the filter cartridge 40 through the inlet 21 formed at the lower portion of the fluid from the outside, And the filtered fluid is discharged through the discharge port 22 formed in the base 20, thereby removing foreign matter from the fluid.

The controller 30 removes the contaminated filter cartridge 40 according to the replacement cycle of the filter cartridge 40. In the present invention, the filter cap 31 is attached to the cover body 30 So that the replacement operation can be performed more quickly and easily.

That is, when the cover body 30 is separated from the filter housing 10, the filter cap 31 blocking the upper end of the filter cartridge 40 is detached together, If the cover body 30 is closed again after replacing only the installed filter cartridge 40, the replacement operation is completed.

Therefore, no separate process for detaching or mounting the filter cap 31 from the filter cartridge 40 is performed, thereby shortening the working time and improving the convenience of the operation.

5 shows a filter cap structure according to a second embodiment of the present invention in which a sealing agent 32 protruding inside the filter cap 31 is attached to an upper surface of the filter cartridge 40, It is confirmed that the elastic body 34 is elastically supported by the elastic body 33 and the cover body 30 is formed with the elastic pad 34 made of a urethane material for supporting the filter cap 31 with a certain elastic force.

The sealing member 32 can be kept in close contact with the upper surface of the filter cartridge 40 owing to the elastic force of the elastic spring 33. As a result, So that the occurrence can be prevented.

In particular, when a pressing force by the elastic pad 34 is additionally applied to the filter cap 31, a gap between the filter cartridge 40 and the filter cap 31 is prevented from being generated, .

6 shows a filter cap structure according to a third embodiment of the present invention. The filter cap 31 is inserted into a hollow portion 41 formed in the filter cartridge 40, (35), and a guide hole (36) is formed in the lower end of the guide pin (35).

A coating layer 37 for enhancing water tightness is formed on the inner wall of the filter cap 31 by increasing adhesion with the filter cartridge 40. The coating layer 37 comprises 40 to 60% by weight of a carboxyvinyl polymer (Carbomer) 10 to 30% by weight of Unsaturated Polyester Resin and 10 to 30% by weight of boron nitride.

In this case, the coupling between the filter cartridge 40 and the filter cap 31 can be more effectively performed in the process of coupling the cover body 30 to the filter housing 10.

That is, in the course of the lowering of the filter cap 31, the guide hole 36 coupled to the guide pin 35 is first inserted into the hollow portion 41 of the filter cartridge 40, So that the filter cartridge 40 can be coupled with the filter cap 31 without being shifted.

Further, since the coating layer 36 formed on the inner wall surface of the filter cap 31 has an elastic force of a certain thickness, the adhesive force to the outer wall surface of the filter cartridge 40 can be increased.

Particularly, the unsaturated polyester resin contained in the coating layer 37 can maintain a uniform thickness of the coating layer 37, and boron nitride is contained therein. Therefore, the gap between the unsaturated polyester resin and the filter cartridge 40 The phenomenon can be prevented.
