1 to 7, the dust collector 100 with improved dust collection performance according to an embodiment of the present invention includes a housing 200, a foreign material separation guide unit 300, a filter unit 400, and a cleaning agent generation unit. do.

The housing 200 is provided to receive sludge or a fluid including a particulate foreign material and a bad odor inside, filter the foreign substances, remove the odor, and then guide the discharge of the purified fluid.

To this end, the housing 200 is provided with an inlet 210 for allowing the fluid containing the odor to flow into the inside, and a first outlet 220 for guiding the discharge of foreign substances contained in the fluid, A second outlet 230 for guiding the forced discharge is provided.

For convenience, the inlet 210 is formed on the lower peripheral surface of the housing 200 , the first outlet 220 is provided at the lower portion of the housing 200 , and the second outlet 230 is located at the upper portion of the housing 200 . assumed to be available. At this time, the inlet 210 , the first outlet 220 , and the second outlet 230 may guide the natural inflow and discharge of a fluid or foreign material, and a control valve is provided to control the inflow and discharge of the fluid or foreign material. can Of course, the housing 200 is applicable to various shapes and various materials.

In particular, the fluid according to the present invention may be applied as a liquid or a gas, but for convenience, it is assumed that the fluid contains an odor.

In addition, the foreign material separation guide unit 300 is provided inside the housing 200 and alternately guides the flow trajectory of the fluid introduced into the housing 200 through the inlet 210 to separate and guide the contained foreign material. Thus, the fluid introduced into the housing 200 through the inlet 210 passes through the foreign material separation guide 300 to separate relatively bulky foreign substances.

The filter unit 400 is provided in the housing 200 to separate and guide the relatively small-volume foreign material contained in the fluid flowing toward the second outlet 230 after separating the foreign material by the foreign material separation guide unit 300 and to induce deodorization. do. At this time, after the foreign material separation guide unit 300 filters out the relatively large-volume foreign material contained in the fluid, the filter unit 400 filters out the relatively small-volume foreign material and the odor contained in the corresponding fluid.

Thus, the purified fluid is discharged (exhausted) through the second outlet 230 . In particular, the transfer pump 250 is provided on the second outlet 230 side so that the fluid flows into the interior of the housing 200 and then forcibly flows along the discharge trajectory.

In detail, the foreign material separation guide 300 includes a partition plate 310 , a communication hole 320 , and a tube 330 .

A plurality of partition plates 310 are provided inside the housing 200 along the axial direction, and partition the inner space of the housing 200 . At this time, it is assumed that the partition plate 310 has a flat plate shape and is integrally provided with the housing 200 . Of course, the partition plate 310 is deformable in various shapes.

In addition, the communication hole 320 is a plurality of through-holes in each of the partition plates 310 to guide the fluid that is forcibly introduced into the inlet 210 and flows toward the second outlet 230 . In this case, the diameter and number of the communication holes 320 provided in each partition plate 310 are not limited.

In addition, the tube 330 is provided on the partition plate 310 corresponding to the edge or inner surface of each of the communication holes 320 so as to protrude upward or downward of the partition plate 310 , and instantly go straight to the flowing fluid. It provides mobility.

In particular, the central axis of each tube 330 of the partition plate 310 adjacent along the axial direction of the housing 200 is staggered in the axial direction of the housing 200 to increase the separation efficiency of foreign substances from the fluid.

In more detail, the partition plate 310 may be evenly disposed along the axial direction in the inner space of the housing 200 , or may be intensively disposed on the upper side or the lower side.

In addition, the communication hole 320 serves to guide the flow of the fluid to be forcibly flowed toward the second outlet 230 through a plurality of through-holes in each of the partition plates 310 .

At this time, the communication hole portions 320 of the partition plates 310 adjacent in the axial direction are not arranged on a straight line in the axial direction of the housing 200 . That is, the communication holes 320 arranged in the vertical direction are arranged to be alternately arranged in the axial direction of the housing 200 , so that the fluid flows along a zigzag trajectory in the inner space of the housing 200 and is guided to be discharged.

In addition, the lower end of each tube 330 provided in the partition plate 310 located at the relatively upper side is located lower (Δh) than the upper end of each tube 330 provided in the partition plate 310 located at the lower side relatively. .

So, after the fluid passing through each tube 330 of the partition plate 310 located on the lower side flows with straightness, the corresponding fluid flows through each tube 330 of the partition plate 310 located on the upper side relatively. As the flow direction has to be changed abruptly to move inward, a portion of the foreign material of relatively large particles and relatively small particles contained in the fluid falls on the partition plate 310 located at a relatively lower side while being separated from the fluid. to accumulate

In addition, each tube 330 may be formed such that the diameter gradually decreases (d1 > d2) as it goes along the flow direction of the fluid inside the housing 200 . This is to increase the separation efficiency of foreign substances from the fluid through the rapid flow direction change of the fluid while the flow velocity of the fluid passing through the tube 330 is increased.

Meanwhile, the housing 200 may include a door 240 that opens and closes a portion of the circumferential surface so that foreign substances that have fallen on the partition plate 310 and have accumulated can be easily removed. One edge of the door 240 is hinged to one edge of the cut-out circumferential surface of the housing 200 by various methods. In addition, the door 240 has the other edge bound to the other edge of the incised circumferential surface of the housing 200 and maintains a closed state, and is released and can be opened.

Of course, the door 240 is deformable in various shapes.

In addition, the partition plate 310 may be separated from the housing 200 in order for the operator to clean and maintain the inner surface of the tube 330 .

That is, the housing 200 protrudes the flange 260 along the inner surface in the circumferential direction, and the partition plate 310 is placed to overlap the corresponding flange 260 . The flange 260 and the partition plate 310 are detachably coupled by a fastening bolt 312 . In this case, through the opening of the door 240 , the operator can separate and install the partition plate 310 inside the housing 200 . Of course, the flange 260 can be applied in various shapes.

In particular, the housing 200 has a recessed seating groove 290 in the flange 260 formed on the inner surface of the other peripheral surface opposite to the one peripheral surface having the door 240 to be opened and closed. Therefore, the partition plate 310 is inserted into the housing 200 in an open state, and then inserted into the front side or the front side and both sides in the corresponding seating groove 290 along the insertion direction to be mounted.

In addition, the partition plate 310 is bound by a fastening bolt 312 in a state in which the other edges except for the front edge or the front edge and both sides which are inserted into the seating groove 290 and seated in contact with the upper surface of the corresponding flange 260 are in contact with the fastening bolt 312 . do. Accordingly, the partition plate 310 can be easily disassembled and assembled inside the housing 200 .

In addition, there is a stagnant space [residual space, dead zone] in which the fluid remains in the space of the housing 200 corresponding to between the partition plate 310 located on the upper side and the partition plate 310 located on the relatively lower side. .

In order to guide the fluid in the stagnant space to flow toward the tube 330 of the partition plate 310 located at the relatively upper side, a vortex generating unit 500 is provided.

That is, the housing 200 is provided with a vortex generating unit 500 on the inner surface between the adjacent partition plates 310 along the axial direction to guide the smooth flow of the fluid and further increase the separation efficiency of the fluid and foreign substances. .

Here, the vortex generating unit 500 includes a baffle 510 , a fitting protrusion 520 , and a hook 530 .

The baffle 510 is provided to protrude on the inner surface of the housing 200 corresponding to the region where the fluid stagnates between the partition plates 310 adjacent in the axial direction of the housing 200 to generate a vortex in the fluid or It serves to increase the strength of the vortex.

Thus, the fluid collides with the baffle 510 and flows toward the corresponding tube 330 while maintaining or increasing fluidity such as a vortex. At this time, as the fluid collides with the baffle 510 , the foreign material contained therein falls on the upper surface of the partition plate 310 .

Of course, the baffle 510 is applicable to various shapes and various materials.

Then, the fitting protrusion 520 extends from the baffle 510 and is axially inserted into the mounting hole 270 of the housing 200 . That is, the fitting protrusion 520 is inserted from the inside of the housing 200 to the outside.

In addition, the hook 530 is inserted into the mounting hole 270 from the outside of the housing 200, and forms a fitting groove 532 to receive the fitting protrusion 520 forcibly.

Of course, the hook 530 may be formed in various shapes, and the number of the fitting protrusion 520 and the fitting groove 532 is not limited. In addition, the hook 530 is inserted or bolted to the mounting hole 270 so as not to be separated to the outside by the pressure inside the housing 200 . In particular, the hook 530 may be made of an elastically deformable material so as to be forcibly inserted into the mounting hole 270 .

In addition, the hook 530 may be provided with a handle 534 to be grasped when removed from the housing 200 . The handle 534 and the hook 530 may be deformed into various shapes.

In this case, the baffle 510 can be tilted by rotating the hook 530 coupled to the hook 530 in the circumferential direction to set the fluidity and flow direction of the fluid.

Meanwhile, the filter unit 400 includes an adsorption filter 410 and an odor filter 420 .

The adsorption filter 410 separates foreign substances, particularly relatively small particles, contained in the fluid after passing through the foreign substance separation guide unit 300, and is provided inside the housing 200 corresponding to the second outlet 230 side. As a result, the foreign material separation guide unit 300 allows the fluid separated from the foreign material to pass through and secondarily separates the foreign material.

At this time, the adsorption filter 410 may be variously applied, such as an electric filter, and may be detachably coupled to and fixed to the upper surface of the housing 200 in various ways.

In addition, the odor filter 420 adsorbs and separates the odor contained before the fluid is discharged to the outside of the housing 200 , and is located on the upper surface of the housing 200 forming the second outlet 230 . The slide is inserted to guide the discharge of the purified fluid by removing the odor contained in the fluid that has passed through the adsorption filter 410 .

In particular, the upper surface of the housing 200 forms a slide groove 280 that is opened to one circumferential surface, and the slide groove 280 is connected to the second outlet 230 . Thus, when the odor filter 420 is completely inserted into the slide groove 280 , it comes into contact with the upper surface of the adsorption filter 410 . In this case, the odor filter 420 may include a handle 422 .

Therefore, after the fluid containing foreign substances and odors is forcibly introduced into the housing 200, it passes through the foreign substances separation guide 300 along the forced flow direction, and first drops the foreign substances onto the partition plate 310, and then the filter unit It passes through 400, and is discharged in a purified state as it secondaryly separates foreign substances and removes odors.

Therefore, the filter unit 400 can increase the cycle of maintenance and increase durability by first separating the foreign substances in the fluid through the foreign substances separation guide part 300 .
