Abstract
The present invention discloses a sediment filter having excellent price competitiveness and a method of manufacturing the same,
The method of manufacturing a sediment filter according to the present invention includes the steps of forming a sediment filter having a hollow portion and heat treating the inner surface of the sediment filter by flowing heat treatment water at a predetermined temperature through the hollow portion.
Description
The present invention relates to a sediment filter and a method of manufacturing the same, and more particularly, to a sediment filter capable of reducing filter material thickness and improving filtration performance by making the structure of a sediment filter dense through heat treatment, .
As is well known, filters are divided into filters for water purifiers and industrial filters. However, these filters are mainly used for filtration / adsorption / ion exchange / sterilization of domestic water or industrial water, and their working principles are similar.
In general, the filters include sediment filters, activated carbon filters, hollow fiber filters, ion exchange resin filters, and reverse osmosis filters. Among them, the sediment filter is a water filter (hereinafter referred to as "water" It serves to filter out the particulate debris contained.
In other words, the sediment filter is a pretreatment sedimentation filter that filters out rust, soil, sand, dust and other debris, including rust, contained in raw water, and removes foreign matter such as rust, It provides an important function to ensure normal operation of the filter.
Conventional sediment filters are mostly provided in a pipe shape or a cylindrical shape, and their thicknesses and lengths are standardized according to whether they are for water purifiers or for industrial purposes. However, in the sediment filter, water flows in the direction of the thickness, and the sediments contained in the water are filtered, so that the sediment filter has a generally large thickness. This increased the cost of materials and caused the unit price to increase.

In the step (a), the sediment filter may have a pipe shape or a cylindrical shape.
Also, in the step (a), the sediment filter includes polypropylene (PP).
In the step (b), the heat-treated water may be controlled to a temperature for thermally denaturing the inner surface of the sediment filter. The temperature of the heat treatment water may be between 100 and 130 degrees, and may vary depending on the material.
In the step (b), a heat treatment apparatus for supplying the heat-treated water to the hollow portion of the sediment filter may be used.
The heat treatment apparatus includes a heat treatment water storage unit for heating and storing the heat treatment water supplied to the hollow portion of the sediment filter at a set temperature; A supply pump for supplying a hydraulic pressure required for flowing the heat-treated water supplied from the heat-treated water storage unit; A supply valve for opening and closing the flow of the heat treatment water supplied from the heat treatment water storage part; And a control unit for controlling the temperature of the heat treatment water stored in the heat treatment water storage unit and controlling the operation of the supply pump and the supply valve.
In the step (b), it is preferable that the heat treatment apparatus is capable of switching the supply direction of the heat treatment water supplied to the hollow portion of the sediment filter in a forward / backward direction. Thus, the flow direction of the heat treatment water supplied to the hollow portion of the sediment filter can be changed in the set cycle, so that the heat treatment can be uniformly performed on the inner surface of the sediment filter as a whole.
According to another aspect of the present invention, there is provided a sediment filter produced by a method of manufacturing a sediment filter, wherein a structure of the inner surface in contact with the heat- Lt; / RTI >
According to the present invention, the sediment filter and the manufacturing method thereof have the advantage that the performance of the sediment filter can be secured while reducing the material cost.
In addition, there is an advantage that the thickness can be reduced and the performance can be improved compared with the conventional one.
In addition, the performance of the filter can be improved by heat-treating the hollow portion of the sediment filter to densely texture the structure.
