The present invention relates to a dust collecting / collecting device filter and a method for manufacturing the same, and more particularly, to obtain a finished product by press molding, heat treatment, molding, Teflon powder coating and heat treatment using an intermediate product (M / B) of thermoplastic synthetic resin. In the dust collecting / collecting device filter and manufacturing method thereof, the intermediate product (M / B) of the thermoplastic synthetic resin is injected by mixing 85 to 95 vol% of synthetic resin, 4 to 13 vol% of activated carbon, and 1 to 2 vol% of water, followed by heat treatment. It is obtained by cooling and cutting.

According to the dust-collecting / collecting device filter of the present invention and its manufacturing method, it can be used as a filter for dust-collecting or collecting-collecting device, and it is possible to obtain a filter having excellent durability and excellent filtering performance through the mixing of predetermined components. .

With the development of the industry, various types of dust and dust are generated at various sites, and the pollution of the water is increasing as well. The method of removing the dust or purifying the water is equipped with an internal dust filter. Dust collector or water collecting device will be representative.

For example, as a method for purifying water quality, a wheeler type was first developed as a lower collection device used in drinking water purification systems, and a strainer type has been introduced since the 1960s. The Pee Block type, hole tube type, perforated plate type, etc. are introduced.

The wheeler type is to install a support on the bottom of the filter paper, and the pressure chamber between the concrete molded article and the bottom of the filter paper, the price is cheap and easy to install, there is a relatively low head loss and easy to replace the gravel layer In other words, it is difficult to equalize equally backwash, and there is a risk of leakage of mortar seams, and there is a drawback of damaging the image due to the rapid filtration water pressure.

The strainer type is arranged in parallel with the block in which the strainer is inserted on the support of the bottom of the filter paper, and there is a pressure chamber between the bottom of the filter paper and the block, which is economical and easy to manufacture and install. Although there is a possible advantage, the loss head is large during backwashing, difficult to maintain flatness during construction, it is difficult to evenly backwashing, there is a fear of closing the strainer hole due to the filter yarn, there is a short durability.

The hole block type is a parallel connection of a hole block having a water supply chamber and a distribution chamber at the bottom of the filter paper, and is uniformly filtered by a plurality of collecting holes arranged on the upper surface of the block of equalizing effect by the two-stage structure passing through the orifice hole. Although the backwash effect is excellent, the construction and installation is simple due to the high cost, the material to be made of material with no significant change in corrosion resistance, durability, or pressure resistance, and the distribution pipe room to be deeper than the bottom of the filter paper. not.

In addition, the perforated tube type is a parallel arrangement of the open pipe to the downhole by installing a support on the bottom of the filter paper, if the inclined hole toward the bottom, the washing water spreads well, the impact of the gravel layer is small There is an advantage, but when the branch pipe and the water pipe is too small diameter, the loss head of the backwasher is unbalanced, so that it is difficult to evenly wash, and when the large diameter is uneconomical disadvantage.

On the other hand, some of the filters used in the lower collecting device has a simple configuration with no special features, and the filters selectively used in various dust collecting devices also include water-soluble resins such as acrylic resins, acrylic thickeners, foaming agents, and bubble stabilizers on the surface of the nonwoven fabric. It is obtained by coating and drying a resin product obtained by blowing an emulsion containing a surfactant, an inorganic filler or a crosslinking agent with air, and most of the core filter supporting the interior is made of a nonwoven fabric.

However, the filter of the nonwoven fabric material has a disadvantage in that the wear resistance, durability, chemical resistance is inferior due to the characteristics of the material, and the size of the pores is limited to a certain standard.

The present invention is to improve the disadvantages of the prior art, a dust collecting / collecting device filter and a method for manufacturing the same, which is obtained by pressing, heat treatment, molding, Teflon powder coating and heat treatment using an intermediate product of thermoplastic synthetic resin, By using a synthetic resin and activated carbon as an intermediate product, it is intended to provide a new type of dust collecting or collecting device filter having excellent durability and filtration performance through a predetermined ingredient formulation and a manufacturing method thereof.
