Reduced volume, light weight, easy to carry, and easy to carry and reduce the manufacturing cost of the mounting frame.There is little content of impurities and bubbles during manufacturing, so the limit of pressure is high, and electrolytic polishing and external polishing are simple. It is economical because it is cheap and low cost, and various deformations and modifications are possible according to the allowable pressure or use and purpose.The fastening of the housing is quick and easy.It is fastened reliably.It is equipped with the rotary sealing member for filter pressing. Free adjustment of length and possible up and down compression at a constant pressure There is no possibility of a mouth relates to a filter housing having a filter crimp structure that can be easily separated to open a little gap and replace the filter when the head and the body reduce unnecessary time and labor with high utilization of space.

The filter used in domestic water purifiers is made of wire mesh, woven fabric, manure paper, glass wool, porous pipes, etc., and the gravity type and pressure reduction type are classified in terms of liquid permeation driving force. · Can be divided into pressure type. Industrial apparatuses include the following.

First, pressure filters are also called filter presses and are widely used. Low residual liquid in solids.

Second, gravity filters are low-cost filters, and sand filters used for the purification of tap water are typical.

Third, lobed filters have better cleaning characteristics than filter presses but are expensive to install.

Fourth, the continuous filter is capable of continuous operation and mass processing as compared to the batch type of the pressure filter, gravity filter, and leaf filter.

Fifth, centrifugal filter (遠 心 濾 過 器) has a batch-type, continuous type, the smallest residual liquid in the solid, but high filtration cost.

Sixth, special filters are generally used for special processes with low throughput. High pressure filter using a porous metal, a pressure filter using a glass fiber packed layer as a filter medium, a vacuum filter using a filter paper, etc. are mentioned.

Such filter selection should be determined in consideration of throughput, concentration and size of solid particles, physical properties of the filtrate, the conditions of filtration, the nature and content of the residue left after filtration.

The filter media of such a filter is a porous medium used for filtration and is also called a filter or filter. The filter media is different depending on the characteristics of the target material. Grain, garnet, activated carbon, diatomaceous earth, anthracite-like media such as particles or powder are used for large-scale water treatment of water and sewage. Sand or anthracite is used in double filtration, while sand, garnet and anthracite are used in triple filtration. A typical filtration method using sand is slow filtration of a water treatment plant.

Fiber forms include filter cloth, paper, felt, sponge, etc., and the application range is wide because of the low price and good dust collection effect. The material of the filter cloth is various kinds by natural fiber and artificial fiber. Carbon, metal, plastic, etc. are used as the porous material, and high mechanical strength is used for industrial high pressure filter. Carbon is especially suitable for filters that must withstand corrosion well.

Separation membrane is used for the membrane separation method which is a desalination technique of industrial water. This medium, called osmotic or semipermeable membranes, is a solid or liquid membrane made of cellulose acetate. Materials to be filtered include dyeing and dye wastewater, heavy water, sewage, heavy metal wastewater, petrochemical wastewater and landfill leachate.

Membrane separation method is a method of separating and removing dissolved substances such as colloids, organics and ions in water by using a semipermeable membrane, also known as membrane separation, membrane separation, or membrane separation.

Since 1960, it has been developed and developed around the reverse osmosis method for desalination of industrial water in the United States. Currently used technologies include microfiltration (MF), ultrafiltration (UF) and nanofiltration (nanofiltration). : NF), reverse osmosis (RO), gas separation (GS), and electrodialysis (ED).

Separation membranes called osmotic membranes or semi-permeable membranes are liquid or solid membranes with very fine pores on the surface and selectively passing certain components. The membrane used is made of cellulose acetate, which has a low water permeability and can filter salts up to 99%.

Certain membrane modules are affected by physical conditions such as the concentration and viscosity of suspended solids in the raw water to be applied, so be careful in selecting the modules to find the most suitable module for your application. Membrane modules developed to date are typical of tubular, hollow fiber, spiral wound, and plate and frame, and rotary disks that can effectively reduce membrane fouling. ) Was also developed.

Conventional separation and concentration processes induce a change in phase, which separates materials, resulting in high energy consumption, and high temperature is required to change the phase. On the other hand, this technique is characterized by a simple process and excellent energy efficiency since it selectively separates materials without changing phases.

In addition, since the material is separated by applying mechanical pressure, it is being proposed as a new application in the separation, purification, and concentration process of specific components, and the range of application is gradually being widened. Applications include the separation and concentration of raw materials in the food industry, the production of ultrapure water used in boilers and semiconductor cleaning processes, the recovery of active substances in wastewater, and recycling technologies.

In Japan and Europe, starting with RO, technologies such as UF and MF are widely used in industrial water production and industrial product production. In Japan, it is practically used in the field of manure treatment, reuse of treated water, and water treatment technology. In Europe and the United States, a lot of research is being conducted on the applicability of UF, MF, NF, etc. to water treatment processes due to the ever-increasing regulations and pollution of water sources.

Currently, domestic water purifiers using UF, MF, RO, and activated carbon of hollow fiber type are being used in fields related to tap water, and research is being conducted for various fields such as practical use in water treatment plants, which are mass processing facilities.

The filter media of the water purifier must have the following characteristics: first, the size of the micropores is appropriate, second, the adhesion is good; third, the hole is not blocked; fourth, it is strong against pressure or friction; fifth, the corrosion resistance is good; sixth, the filtration resistance is small, and the seventh, It must be cheap.

The filter medium having this characteristic has to be discarded after use for a certain period of time and replaced with a new filter medium, which is usually fixedly installed in the rod-shaped filter housing.

3 is a cross-sectional view of the main portion showing the mounting of the conventional stainless steel filter housing, the conventional filter housing is the head 120 subjected to the water purification process by the filter 40, and the water to support the filter 40 and to be purified It consists of a body 100 for supplying.

The head 120 is forged by die casting and screwed into the thread 124 in the head 120 and the thread 108 in the upper portion of the body 100.

The support long axis 102 protruding upward from the upper center side of the body 100 is fixed, and the outer side of the filter lower fixture 104 which minimizes the upper contact area is formed to protrude upward. On the side of the body 100 is formed an inlet 106 for supplying the water to be purified to the outside of the filter 40.

The upper inner side of the head 120 is formed on the extension of the filter lower fixture 104 of the body 100, the upper filter outlet 122 is formed to protrude to the lower end in the center of the purified water through the filter 40 to the outside A discharge port 118 is discharged to form.

The filter 40 is formed with packings 45 and 44 at the top and the bottom, respectively.

Most of these filter housings 10-inch or 20-inch stainless steel filter housing for mounting one filter 40 is mostly produced by die casting the upper head 120 portion.

Die casting is a casting method used for casting production and is also called die casting. It is a precision casting method in which molten metal is injected into a steel mold precisely machined so as to completely match the required casting shape, thereby obtaining the same casting as the mold. The product is called diecast casting.

In addition to the advantages of almost no need for finishing because the dimensions are accurate, it has excellent mechanical properties and mass production. Metals used are alloys such as zinc, aluminum, tin, copper, magnesium and the like, and are cooled and solidified by injection by pneumatic pressure, hydraulic pressure or hydraulic pressure using a die casting machine.

It is known that the stainless steel filter housing formed by die casting has a high degree of impurity due to the frequent occurrence of bubbles due to the inflow of air into the product during the manufacturing process and the introduction of various foreign substances into the solution during the casting process.

Since the cracks are generated at the site where the bubbles are generated, serious defects are generated, so that they are usually manufactured thickly.

Since the separate fastening tool is required for the fastening, the filter 40 has had a troublesome replacement. The packing 110 is positioned and sealed between the body 100 and the head 120.

In addition, when the filter 40 is replaced, since the filter 40 can be replaced only by lowering the body to the lower portion of the head 20 by the length of the support shaft 102, there is a problem that a space for replacing the filter 40 must be secured. there was.

In addition, the filter 40 has a length difference of about 20 millimeters between the same standards according to the manufacturer.

As a result, there is a difference in the degree of compression with the housing of the upper and lower parts of the filter 40 for complete compression, but the inner diameter and the outer diameter of the filter 40 are not a problem within a certain standard, but the problem is the filter 40 Of the packing 40 on the pressing surface according to the length of the filter and the material of the filter 40 (polypropylene, ceramic, pound filter, granular carbon filter, fibrous carbon filter, block carbon filter, etc.) in the filter type filter 40 And, according to the compression area and the degree of elasticity according to the material of the packing 40, the raw water in the housing can not be purified through the filter 40, the outlet through the gap between the upper end of the filter 40 and the filter upper fixing part 122 There was a problem that it may be introduced into the (118) as it is, there is a problem that can not be adjusted accordingly according to the expansion or contraction of the filter 40, as well as appropriately corresponding to it.

The present invention is to solve the problems described above, by processing the head portion of a high-purity stainless rod precisely welded, and then increase the hygiene by electropolising and remove impurities to reduce the volume of the unnecessary head portion weight It is very light and easy to carry, and it reduces the manufacturing cost of the mounting frame when it is installed.There is little impurities or bubbles in the manufacturing process, so it has a high limit of pressure, electrolytic polishing and external polishing, and the cost is low.
