Devices such as ships, automobiles, heavy equipment, and power generation facilities drive devices by sucking air in the atmosphere. They are equipped with an air intake system. The air intake system must remove foreign substances from the air and inhale only pure air. For this, filters are used. The air contains large foreign matter (leaves, insects, etc.), which must be mounted before functional filters (antibacterial and sterilization, odor removal, etc.). The present invention aims to pre-remove large foreign matter. A pre-filter is formed for pre-removal of large foreign substances, and the pre-filter is mounted inside the main housing and rotated. A brush is mounted on one side of the pre-filter, and the brush and the pre-filter are in close contact. The brush forms a number of brushes to sweep the filter surface. That is, the large foreign matter attached to the surface of the pre-filter is removed by a brush. To achieve this, the pre-filter is formed of a rotating filter, and the brush is mounted inside the main housing.

[Example 1-2] In Example 1-1, the main housing is formed in a cylindrical shape, and the rotary filter includes a disc shape.

The rotating filter of the present invention is installed inside the main housing, and rotates inside the main housing. Therefore, for smooth rotation of the rotary filter, the rotary filter shape takes a disk shape. In order to accommodate the disk-shaped rotary filter, the inside of the main housing is formed in a cylindrical shape.

In order for the rotary filter to be rotated inside the main housing, the may housing must be divided into first and second main housings, and a rotary filter is inserted into the first and second main housings. The divided first and second main housings are fastened by a connecting means 130.

[Example 1-4] In Example 1-1, one or both ends of the main housing form a flange 140, and the flange includes a plurality of fasteners 141.

Both ends or one end of the main housing accommodating the rotary filter form a flange. The flange facilitates coupling with other devices. The flange forms a plurality of fasteners, and the fasteners are fastened by inserting bolts and nuts. Therefore, it is easily combined with other devices. A configuration capable of combining two configurations on behalf of the bolts and nuts may be used by substituting the equivalent object.

[Example 1-5] In Example 1-1, the through holes are the same size, and include uniformly and / or non-uniformly arranged.

The pre-filter filters out large foreign matter (insects, leaves, sand, gravel, etc.) in the air. Therefore, the rotary filter passes only air and must filter foreign objects. To this end, both sides of the rotary filter are formed with a plurality of through holes (through holes). The through hole may be implemented by changing to a predetermined size according to the purpose for which the rotary filter of the present invention is used. In particular, various models are formed according to the size of the through-holes of the rotary filter, and diversity of use can be secured by changing the model of the rotary filter.

[Example 1-6] In Example 1-1, the rotary filter includes a polymer or a metal.

Moisture may be included in the foreign matter, and when used in a marine environment, it may be used in a high humidity environment. If the humidity is high, the rotary filter can be corroded. To overcome this, the rotary filter material is formed of polymer or metal, and in the case of metal, stainless steel is preferred. Particularly when it is made of metal, it is preferable to coat the polymer on the surface.

[Example 2-1] In Example 1-1, a rim 220 formed on an outer periphery of the rotary filter and protruding outside the housing; and a power transmission means 400 rotating the rim; do.

The rotary filter is rotated inside the main housing and must be rotated with external power. To achieve this, a rim is mounted outside the rotary filter. The rim is thicker than the rotary filter. This is to secure the weight to obtain a centrifugal force when rotating. In addition, the outer periphery of the rim is supplied with rotational power as an external power.

[Example 2-2] In Example 2-1, both ends of the rim are coupled between the first main housing and the second main housing, and include a bearing 230 inserted into the coupling surface.

[Example 2-3] In Example 2-2, the bearing includes an oilless bearing or Teflon.

Both ends of the outer periphery of the rotary filter are in contact with the first and second main housings. Friction occurs during the contact process, which causes rim or main housing abrasion. To prevent this, mount a bearing. In addition, the bearing is used for smooth rotation, which is to improve the power efficiency of the power transmission means. It is preferable to use Teflon rings or oilless bearings.

[Example 2-4] In Example 2-1, the gear 411 formed on the outer periphery of the rim; a pinion 412 engaged with the gear; a motor 441 and a reducer driving the pinion (442) ;.

[Example 2-6] In Example 2-1, the driven sprocket 431 formed on the outer periphery of the rim; the driven sprocket 432 coupled with the driven sprocket and chain 433; and the driven sprocket It includes; a motor 441 and a reducer 442 to rotate the.

To rotate the rim of the rotary filter, a motor 441 is mounted on the main housing, and a reducer 442 is mounted to decelerate the rotational speed of the motor. The reduction gear rotational energy is transmitted to the gear through the pinion, or to the driven pulley which is connected to the prime pulley and the belt, or is cut into a driven sprocket which is chained to the prime sprocket. The gear, driven pulley, and driven sprocket presented above are mounted on the rim. That is, the motor rotational force rotates the rotation filter.

[Example 2-7] In Example 2-1, the power transmission means includes a main housing.

The power transmission means is combined with the main housing or mounted externally. The combination of the main housing and the power transmission means reduces the pre-filter space and is for modularization. When the power transmission means is combined with the main housing, a vibration mount is mounted to prevent resonance due to vibration. The anti-vibration mount is equipped with a rubber plate or a spring.

[Example 3-1] In Example 1-1, the brush 300 is mounted on one side, and a brush support body 310 is mounted on the inner circumference of the main housing.

The brush is in close contact with one surface of the rotary filter. The brush is coupled to the brush support, and the brush support is mounted inside the main housing. The brush is formed in a straight line and is installed from the center of the rotating filter to the outer periphery. That is, in one revolution of the rotary filter, the brush makes contact with the entire surface of the rotary filter. As another embodiment, the brush may be formed over the entire diameter of the rotary filter, and as another embodiment, a plurality of rotary filters may be mounted.

[Example 3-2] In Example 3-1, a cylindrical shape, an outer circumferential surface is combined with an inner surface of the main housing, and a brush fixing body 320 to which the brush support is fixed.

The brush support on which the brush is mounted is coupled inside the main housing. Since the brush is a consumable, it forms a replaceable structure. Therefore, the brush fixing body is inserted and coupled inside the main housing, and the brush fixing body and the main housing are easy to mount and detach. The brush fixture can be directly coupled to the main housing, or can be combined by other configurations. For this, a brush fastening is used. The brush fastening is used in a configuration that combines the brush fixing body and the main housing. The brush fastening can be combined by a plurality of bolts or by an elastic clip. In addition, it is formed in a ring shape to form a male screw on the outer periphery, and can be fastened by forming a female thread on the inner periphery of the main housing.

[Embodiment 3-4] In Embodiment 3-2, the other side of the brush support body includes a combination of the brush fixing body and the elastic means 330.

[Example 3-5] In Example 3-4, the elastic means includes a coil spring or a plate spring.

The rotary filter is rotated in contact with the brush. Frequent rotation wears the brush. When used for a long time, the gap between the rotating filter and the brush increases. To solve this, the brush support body and the brush fixing body combine elastic means. The elastic means is equipped with a spring, it is preferable to specifically use a coil spring or plate spring. The elastic means imparts a constant elastic force to cause the brush support to adhere to the rotary filter at a constant pressure in one direction. Therefore, despite the wear of the brush, a certain pressing force is generated, which can effectively remove foreign substances attached to the surface of the rotary filter.

[Example 3-6] In Example 3-1, the injection nozzle 340 formed on the brush support body; includes.

When a foreign substance is attached to the rotary filter, the brush primarily removes the foreign substance. If the foreign matter is not removed by a brush, the foreign matter can be removed by pneumatic or hydraulic pressure. For the pneumatic or hydraulic jetting, a spray nozzle is formed on the brush support. The injection nozzle is formed in plural. The ejection direction of the ejection nozzles is directed toward a part or the front of the rotary filter. The injection speed of the injection nozzle may be the same or different.

[Embodiment 3-7] In Embodiment 3-6, an injection water supply pipe 351 for supplying injection water to the injection nozzle 340; and an injection water control valve 352 formed in the middle of the injection water supply pipe Includes ;, the injection water pump 353 formed in the middle of the injection water supply pipe ;, an injection container 354 in communication with the injection water supply pipe.

[Example 3-8] In Example 3-7, the injection water control device 355 for controlling the injection water control valve 352 and the injection water pump 353 includes.

When the injection nozzle ejects the water pressure, in order to generate water pressure, the injection water of the injection container is received, and the received injection water generates pressure by the injection water pump. The spray water sprays water through the spray water supply pipe and the spray nozzle. In order to control whether the injection water is ejected or not, the injection water control valve is installed in the middle of the injection water supply pipe, and an injection water control device is installed to control the operation of the injection water pump and the injection water control valve.

[Example 3-9] In Example 3-8, the cleaning liquid supply container 356 accommodated in the injection container is included.

It is possible to spray the cleaning solution for cleaning at the same time as spraying water on one surface of the rotary filter. To this end, the cleaning liquid supply container is accommodated inside the spray container, and the cleaning liquid of the cleaning solution supply container is mixed with the spray water inside the spray container. The cleaning liquid is mixed with the sprayed water and discharged to the spray nozzle. The injection container is equipped with a mixing device. The mixing device rotates the fluid inside the spray container for smooth mixing of the cleaning solution and the spray water.

[Example 4-1] In Example 1-1, the suction tube 500 which communicates with the inside of the main housing and sucks air and foreign matters.

[Example 4-2] In Example 4-1, a suction valve 501 communicating with the suction tube; and a suction pump 502 communicating with the suction tube.

[Example 4-3] In Example 4-2, a suction controller 503 for controlling the suction valve and the suction pump is included.

The foreign matter filtered by the rotary filter is discharged outside the main housing. To this end, a suction tube is mounted inside the main housing. Since the suction tube sucks air, a suction pump for air suction is formed outside the main housing. The suction tube operation is intermittently operated as needed. To this end, a suction valve is mounted, and the suction valve is operated at an operating time point by a suction controller. To increase the suction effect, a suction chamber is installed between the suction pump and the suction valve. The suction chamber maintains a constant match and generates an instantaneous suction force when the suction valve is operated.

[Example 4-4] In Example 4-1, the inside of the housing is partially formed, formed as a groove, and an induction groove 130 communicating with the suction tube.

The foreign matter attached to the surface of the rotary filter is separated by a brush when the rotary filter is rotated, and the separated foreign matter is collected under the main housing. Since the collected foreign matter has to be discharged outside, the inside of the main housing forms an induction groove. The suction tube is formed inside the guide groove.

[Example 5-1] In Example 4-1, a blocking plate 600 mounted to the main housing opening is included.

[Example 5-2] In Example 5-1, the blocking plate includes a first blocking plate 610 formed on one side of the main housing; And / or a second blocking plate 620 formed on the other side of the main housing.

The openings at both ends of the main housing should be sealed to improve the efficiency of discharging foreign substances inside the main housing. For the sealing, blocking plates are installed at both ends of the main housing. The operation of the blocking plate closes both ends of the main housing, and foreign matter collected under the main housing is discharged to the outside of the main housing through the suction tube. The blocking plate is operated by an external power. Each blocking plate may be blocked by each power source, or may be blocked by one power source. The power source is preferably made of a motor and a reducer. When each blocking plate is operated by one power source, each blocking plate is operated by rotation of the blocking plate rotation axis, and each rotation axis is combined with one power source. That is, the power source drives each rotation shaft at the same time, and for this purpose, it is operated by gear coupling, chain coupling, rope coupling, and belt coupling.

[Example 5-3] In Example 5-1, the rotation axis of the blocking plate includes being controlled by the suction controller signal.

It is preferable to suction only when the blocking plate is closed. To control this, the blocking plate is driven by the suction controller signal.

[Example 5-4] In Example 5-2, the second blocking plate is formed at an air intake port, and includes a free flow groove 630 formed through the blocking plate.

[Example 5-5] In Example 5-4, the free-flow groove cross-sectional area includes the same or larger formation of the suction tube cross-sectional area.

When the inside of the main housing is sealed with a blocking plate, the effect of inhaling foreign substances can be enhanced. However, when completely closed, suction efficiency is rather reduced. This is because the inside of the main housing forms negative pressure by suction. To prevent this, a free flow groove is formed in the blocking plate. The free-flowing groove is intended not to generate negative pressure inside the main housing by inhaling external air. The free flow groove is formed to be smaller than or equal to the suction tube cross-sectional area. This is to improve suction efficiency.
