The present invention relates to an air filter automatic cleaning device for purifying air, and more particularly, the structure of the cleaning equipment has been drastically improved to enable automatic cleaning of air filters installed in multiple stages by a rotation operation of a nozzle pipe connected to a water supply pipe. It relates to an air filter automatic cleaning device for air purification.

In general, an air purifier is installed in industrial facilities such as tunnels, subways, department stores, factories, hospitals, and other business buildings to remove oil dust, moisture, and dust generated from the facilities. In general, a plurality of air filters are used to collect various foreign substances, and it is well known that the air filters are essentially washed to prevent semi-permanent use of the air filter and deterioration of dust collection efficiency. Many devices for cleaning air filters have been invented.

However, most of the prior art invented, for example, Korean Utility Model Publication No. 97-4373, Domestic Patent Publication No. 99-69940, Domestic Utility Model Publication No. 98-55633, Domestic Utility Model Publication No. 99-22336, According to Korean Patent Publication No. 2000-1023, Korean Utility Model Publication No. 97-4373, Domestic Utility Model Publication No. 97-49188, Domestic Utility Model Registration No. 193384, Domestic Utility Model Registration No. 278552, The multi-stage air filters are equipped with a plurality of injection nozzles, which are provided with a plurality of injection nozzles, to move up and down or left and right by chains or moving guides, or to separate water supply pipes for each layer of air filters. Thus, a structure is provided in which a plurality of nozzles are provided to spray-wash the washing water, respectively.

However, in the case of the conventional structure in which the water supply pipe is cleaned while moving with respect to the air filters of each layer, air filters are naturally required because a plurality of chains, chain wheels, and guide members for driving the water supply pipe are required. The cleaning structure of the washing machine is complicated, and there are many defects in the maintenance and repair of the washing facilities due to the unstable operation due to the movement of the water supply pipe, the hassle of lubrication to induce the smooth operation of the driving means, and the noise caused by the movement. There is a structural problem that causes difficulties.

In addition, the structure in which the washing water is injected through the water supply pipe installed in each layer of the air filter is less complicated than the moving structure provided with the electronic driving means, but the air filters are simply horizontal or horizontal with respect to the housing. Since the water supply pipe located in the air filter of each layer is fixedly installed, the number of injection nozzles is increased because four air nozzles are used to clean one air filter for even spraying of the washing water. In addition, a number of structural problems, such as a lot of waste of the washing water per unit area by using a plurality of injection nozzles, as well as the maintenance cost of water and the like will be increased.

As a matter of fact, in the air purifiers currently installed in each air purifying facility, as described above, defect repair is most frequently generated due to the adoption of a driving means for reciprocating movement of the water supply pipe. Due to the fact that there is a significant problem in maintenance due to the increase of the back, the industry is urgently required to improve the structure of this part.

Therefore, the present invention has been invented to solve such a conventional problem, the object of the present invention is to install a zigzag air filter with simplification of the cleaning structure due to the non-adoption of the drive means for reciprocating movement of the water supply pipe Automatically clean the air filter for the air filter by installing the nozzle pipe connected to the water supply pipe rotationally by the geared motor so as to efficiently clean the air filters in each layer without having a plurality of nozzles. To provide a device.

According to the present invention, the air filter is preferably configured to enable one-way or two-way cleaning.

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

1 and 2 are a schematic front view and a plan view showing a structure of a cleaning device for an air filter according to the present invention. In particular, FIGS. 1 and 2 show a cleaning structure in which the nozzle pipe 20 to be described later is installed in only one direction.

As shown in FIG. 1, an air filter 10 for collecting various foreign matters contained in the air is multi-stage with respect to the plurality of support bars 2 inside the housing 1 having both ends open and having a substantially rectangular shape. The compartment is installed.

As shown in FIG. 2, the air filter 10 partitioned into the housing 1 in multiple stages is connected in a zigzag (W-shape) shape to form a right angle with respect to the support bar 2, where the air filter 10 is provided. Zig-zag is designed to have a good cleaning efficiency in consideration of the cleaning equipment of the present invention, but is not necessarily limited thereto, and installation in other forms in consideration of the working environment such as the installation location and size of the cleaning equipment. As much as possible. For example, horizontal installation or inclined installation is also possible.

1 and 2, the lower part of the housing 1 is provided with a drainage tank 3 for cleaning the air filter 10 and collecting the washed water to be discharged to the outside. At the bottom of the housing 1, which forms a bottom, a filter for preventing scattering of water 4 to prevent scattering of the sprayed particles falling to the bottom when the air filter 10 is washed and to filter out various foreign substances contained in the dropped washing water is provided. Laid down

By providing such a washing water preventing filter 4, the floor around the exhaust port is prevented from getting wet by the water falling during washing, and also the removal and collection of foreign matters is possible to improve the air purification efficiency together with the air filter 10 You can not.

In addition, the air filter 10 of each partition layer installed in the housing 1 in multiple stages as shown in Figs. 5a and 5b forms a drip tray 12 communicating with the support bar 2, respectively, so that the water falling upon washing It is preferable not to drop to the air filter is located, it is preferably configured to prevent the contamination of the other air filter 10 of the lower by the sewage falling by inducing to fall directly to the drain tank 3 through the support bar (2). .

Referring back to FIG. 1, a nozzle pipe 20 which is rotated with respect to the water supply pipe 22 is installed in the air filter 10 partitioned into the housing 1 in multiple stages, and the nozzle pipe 20 is provided in multiple stages. An injection nozzle 24 for evenly injecting water is provided to the air filter 10 of each layer partitioned by.

The nozzle pipe 20 is rotatably connected to one end of the water supply pipe 22 by a swivel 26, and both sides of the nozzle pipe 20 are mounted on a bearing support 28 mounted on the upper and lower portions of the housing 1. It is supported by each of the meeting materials. For example, by connecting the rotary fitting 26, both ends are supported by the bearing support 28 irrespective of the water supply pipe 22, thereby allowing free rotation.

On the other hand, in the case of the present invention, each injection nozzle 24 installed as the nozzle pipe 20 is preferably a rotational injection angle of about 90-110 °, but is not necessarily limited thereto, the air filter 10 It will be possible to change the design by the installation angle or the operation of the nozzle pipe rotation operation means 30 to be described later.

As the nozzle pipe 20, it is preferable to install and use only a single injection nozzle 24 for injecting water to the air filter 10 of each layer. However, if necessary, the size of the air filter 10 In view of the injection angle of the injection nozzle 24, it will be possible to use a plurality of installation.

The rotation operation means 30 which rotates the nozzle pipe 20 within a predetermined angle range is arranged in the orthogonal direction with respect to the nozzle pipe 20 as shown in FIGS. 1, 3, and 4, and the bracket ( It consists of a shaft 32 rotatably installed by a bearing support 31b attached to 31a) and a geared motor 34 connected to the shaft 32, and on the nozzle pipe 20 and the shaft 34. Each of which includes gears 36 and 38 fixedly engaged.

Therefore, the nozzle pipe 20 receives the rotational force from the shaft 32 connected with the geared motor 34 about the water supply pipe 22 connected to the rotary fitting 26 and rotates within a predetermined angle range while being spray nozzle ( It is possible to spray water through 24).

On the other hand, as shown in FIG. 6, the rotation operation angle θ of the nozzle pipe 20 is controlled by the geared motor 34 in consideration of the installation angle of the air filter 10, but the sensing sensor 40 as shown in FIG. 3. It is a matter of course that the geared motor 34 is controlled to control the rotational operation distance of the nozzle pipe 20 more reliably.

In Fig. 1, reference numeral 50 denotes a pump connected to a water supply pipe 22 to pump water from a water supply source, and 52 is an electron valve.

A cleaning state of the air filter 10 according to the present invention configured as described above will be described with reference to FIGS. 1 and 2.

Although the cleaning of the air filter 10 may be performed by an artificial manipulator, it is generally designed to be automatically controlled according to the degree of collection of foreign matter.

Therefore, when the pump 50 and the geared motor 34 are operated by this automatic control operation, water pumped from the water source by the pump 50 is supplied to each nozzle pipe 20 through the water supply pipe 22. In addition, the water supplied to the nozzle pipe 20 is evenly sprayed to the air filter 10 on the front through the injection nozzle 24 located in the air filter 10 of each layer.

In addition, the nozzle pipe 20 through which the water is injected through the injection nozzle 24 is rotated within a predetermined angle range by the operation of the shaft 32 connected to the geared motor 34.

That is, since the gear 36 of the nozzle pipe 20 is meshed with the gear 38 of the shaft 32, the gear 36 of the nozzle pipe 20 is interlocked with the shaft 32 receiving the power generated from the geared motor 34. In addition, both sides of the nozzle pipe 20 are stably supported by the bearing support 28, and the rotating pipe 26 is freely rotated regardless of the water supply pipe 22.

Accordingly, the nozzle pipe 20 which is rotated continuously and repeatedly by interlocking with the shaft 32 which is rotated by receiving power from the geared motor 34 to the air filter 10 of each layer provided in multiple stages with respect to the housing 1 is rotated. Water is sprayed evenly through the injection nozzle 24 of the) to enable the repeated cleaning of the foreign matter, and at the same time the water injected into the air filter 10 is connected to each drip tray 12 or the like as shown in Figure 5a, b Dropping is discharged through the support bar (2) to the sump (3) located below the housing (1) to prevent the transfer of pollutants between the layers.

In addition, the water falling to the lower portion of the housing 1 is dropped into the washing water scattering prevention filter (4) to prevent scattering around the exhaust port and at the same time various foreign matters are collected by the lower drain tank (3).

On the other hand, when the cleaning of the air filter 10 is completed, the water remaining in the nozzle pipe 20 and the water supply pipe 22 through the electromagnetic valve 52 is discharged to the outside. The operation of discharging water by the electronic valve 52 after such cleaning is particularly useful for preventing freezing in winter.

Thus, in the present invention, the nozzle pipe 20 provided with the injection nozzle 24 is rotated at a predetermined position without moving up, down, left, and right, and thus the air filter 10 of each layer is provided in multiple stages in the housing 1. It will be possible to repeatedly clean the foreign matter collected in.

7 and 8 are schematic side and plan views showing a bi-directional cleaning structure using the nozzle pipe 20 according to the present invention, and are shown on both sides of the air filter 10 as compared with the one-way cleaning structure of FIGS. 1 to 2. A nozzle pipe 20 connected to the water supply pipe 22 is further installed, and the nozzle pipe 20 and the shaft 32 are interlocked with each other, and then a power transmission member such as a timing belt for the geared motor 34 ( 60) It is the same configuration except that the components are connected to each other to be rotated at the same time and water is sprayed from both sides to be cleaned.

Therefore, by installing the nozzle pipe 20 with the injection nozzle 24 to both sides of the air filter 10 and configured to spray water while being rotated at the same time by the operation of one geared motor 34, water from one side The cleaning efficiency of the air filter 10 can be further increased as compared to the spraying of the air.

Of course, in this case, there may be a risk of waste of water compared to the one-way cleaning, but in the case of the two-way cleaning, since the cleaning efficiency per unit area is higher than that of the one-way cleaning and the cleaning is completed in a short time, it is practically maintained. The increase in management costs will not be incurred.

Furthermore, in the case of bidirectional cleaning, the nozzle pipe 20 has a technical advantage of enabling more efficient cleaning because the rotational states of the nozzle pipe 20 are reversed with respect to the air filter 10 as shown in FIG. 8.

On the other hand, in the present invention, each member, such as the rotating operation means installed under the housing, for example, the shaft 32, the motor 34, and the bracket 31a and bearing bearing 31b for supporting the shaft, is not shown in the drawings. Because it is protected by aesthetics as well as the noise generated by driving is prevented.

As described above, according to the present invention, since the nozzle pipe connected to the water supply pipe simply rotates in place and sprays water to clean the air filters, the overall structure of the cleaning equipment is very simple and compact, so that the water supply pipe having a conventional nozzle is vertically up and down. Compared to the cleaning equipment moved to the left and right, the installation space is narrow, and the cost and operating cost can be significantly reduced, noise is prevented, the cleaning efficiency is increased, and the overall maintenance of the equipment becomes very convenient.

In addition, since the present invention sprays and sprays water evenly with one jet nozzle on each layer of air filters partitioned by zigzag, the conventional fixed scrubbing structure uses four nozzles for one air filter. Compared with the structure, the number of spray nozzles is not only significantly reduced, but also has the advantage of preventing the waste of water and significantly reducing the water consumption.

In addition, the cleaning equipment according to the present invention also has the advantage that more efficient cleaning is possible by installing and cleaning both sides of the air filter if necessary.

Although the present invention has been described with reference to the accompanying drawings, it will be understood that many modifications and changes may be made without departing from the scope of the following claims. For example, the air filter has been described in a zigzag form, but it is not necessarily limited as long as it can be cleaned using the cleaning equipment of the present invention.
