Description

Filter device {FILTER APPARATUS}

The present invention relates to a filter device, and more particularly, to a filter device that can improve the filter performance and economics according to the increase in the filtering area.

Common air conditioning and industrial dust collection systems include a filter unit consisting of a multi-stage dust collection filter. Such a filter device is generally composed of a primary filter and a secondary filter. The primary filter is an auxiliary filter, and serves to filter dust and foreign substances having a large particle diameter. In contrast, the secondary filter serves as a main filter that collects fine dust of a level required in actual development.

On the other hand, the filtration filter device can determine the performance based on three physical concepts: the size of the pores through which air can pass, the porosity using the ratio of the total pore area to the total filter area, and the filtering area. First of all, the pore size is a value directly related to the size of the dust to be filtered out. Since the porosity means an area that can actually be aired in the entire area of the filter, the closer to 100%, the smoother the flow of air, thereby lowering the differential pressure of the air and increasing the processing air volume. In addition, the filtration area is a factor that can increase the total amount of air treatment as the area of the filter is wider.

Generally, the primary filter is a low pressure differential filter such as a nonwoven fabric and a mesh filter having a large particle diameter, and a filter having excellent air permeability is used, or a centrifugal force such as a cyclone is used where a large amount of dust is generated, such as an industrial site. The dust collecting method used can be adopted. As the secondary filter, a medium filter having a fine particle diameter is mainly used, and a bag filter that can be dedusted may be applied in an industrial site.

On the other hand, the medium filter used as the secondary filter is manufactured in a size of approximately 592 * 592mm in accordance with the air conditioning duct specifications, it is formed of a material that the air flow is not smooth due to the fine particle diameter and low porosity. Therefore, the medium filter is manufactured in a bent form and has a thick structure that can maximize the area of the filter in a predetermined area. However, due to the filter structure deeply bent in a narrow area, dust collection is difficult to collect dust, which causes a problem of being used for single use.

In addition, in the case of an industrial dust collector, a cylindrical bag filter which is formed of a synthetic fiber having rigidity as a secondary filter and which can be dusted is mainly used. In the case of the cylindrical bag filter as described above, as it is connected to the dust removal means such as the intensity, air pulse, etc., it has the advantage of maintaining a long life. By the way, the bag filter has a disadvantage that the volume of the equipment is large and expensive as the quantity thereof is determined according to the amount of air required to be processed. In addition, there are disadvantages that are difficult to manufacture.

The present invention has been made in view of the above problems, and an object thereof is to provide a filter device capable of improving filter performance according to an increase in filtering area.

Another object of the present invention is to provide a filter device that can increase the service life of the filter without a separate dust removal means by providing a plurality of filters in the vertical direction so that the dust can be removed.

A filter device for achieving the above object is configured to include a filter unit and a support unit.

According to a preferred embodiment of the invention, the filter unit comprises a plurality of filters, in particular a planar filter. Here, the plurality of filters may be arranged in parallel to each other in parallel to each other with respect to the inflow direction of the air, the plurality of filters may be formed in a multi-layer.

The support unit detachably supports the plurality of filters and is formed to penetrate the air inlet and outlet so that they do not face each other. Specifically, the support unit may support the front surface of the filter on the basis of the inflow direction of air, and the first inlet of the air inlet is provided at a predetermined interval, the inflow direction of the air to face the first support member The second support member, which supports the rear surface of the filter and the air outlets are spaced apart from each other by a predetermined interval, interconnects the lower portions of the first and second support members, and a collection port through which the collected dust is discharged is provided. And a third support member, and a fourth support member facing the third support member by interconnecting upper portions of the first and second support members. In this case, the inlet and the outlet are formed at positions intersecting the filter so as not to face each other, so that air can pass through all of the plurality of filters.

According to the present invention, the plurality of support members selectively open the plurality of filters, and for this purpose, the fourth support member is hinged to be rotatable relative to the second support member. However, it is obvious that a modification in which the third support member is hinged to be rotatable relative to the second support member is also possible.

In addition, at least one of the first to fourth support members may be provided with a guide rail formed of a sealing material to guide the mounting and flow suppression of the plurality of filters.

On the other hand, the lower portion of the support unit is provided with a container communicating with the lower portion of the support unit, that is, the collection port of the third support member so that the dirt filtered from the plurality of filters are collected by falling.

According to the present invention having the configuration as described above, first, by having a support unit provided so that the inlet and outlet do not face each other with the filter therebetween, the air including the dirt can pass through all the plurality of filters. . As a result, the filtering area through the plurality of filters can be increased, thereby improving the filter performance.

Second, as the filtering area can be freely adjusted by adjusting the number of filters, the volume of the filter device can be freely adjusted. Therefore, it is possible to provide a filter device with improved adaptability to the use environment.

Third, as the filter is detachably installed in the vertical direction with respect to the support unit, the dust can be removed without additional dust removal means, thereby improving the life of the filter. Therefore, it is possible to provide a filter device with improved economics.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
