Description

Rain receptacle filter to prevent stench}

The present invention relates to an excellent receiving sieve, and more particularly to an excellent receiving sieve screen that prevents the odor coming up from the drain is installed in the rain gutter and prevents the odor from remaining debris.

On the roadside, storm drains are installed to drain rainwater. Storm drains can be connected to sewers or other drains and sent to septic tanks or drained directly to rivers or rivers.

When the rainwater is drained, the sieve screen filters the debris such as fallen leaves, twigs, paper, vinyl, bag of confectionery, grass roots, and stones into the drain pipe and drains only the rainwater when the rainwater is drained.

As such, because the rain catcher is always in communication with the drain pipe, it is difficult to prevent the odor coming up through the drain pipe.

In order to prevent such odors, as shown in FIG. 1, the odor prevention device 20 is installed at the lower portion of the collecting container 10 in which the discharge port is formed. Prevents odors from entering

Looking at the structure of the odor prevention device 20, the outlet is opened and closed by the opening and closing door 24 fixed to the hinge 22 held on the spring, rain water is collected in the collection box 10, the opening and closing door 24 from above Press to open and close the door and drain the rainwater through the outlet. When the rainwater is removed and the external force is removed, it is closed by the spring restoring force inside the hinge so that the odor through the drain pipe does not flow back.

When opening and closing the opening and closing door using the spring, the operation is initially performed smoothly, but as time passes, the spring loses its elasticity, causing problems that do not operate properly.

In addition, since the filter sieve has a structure in which the junk is always stacked, even if the drainage is closed, if the rainwater is accumulated in the strain, there is a problem in that organic matter contained in the junk decays and odor is generated.

The present invention is to solve the problems as described above, to maintain the homeostatic function of the opening and closing doors over time, and to prevent the debris (organic matter) stacked in the collection box does not decay odor through the drain pipe It is intended to provide an excellent receiving strainer to prevent bad smell. In addition, even if a large amount of contaminants are stacked in the collection container, some of the flow path is open to facilitate the discharge of rain water.

The present invention is installed in the rainwater inlet of the storm receiver in order to achieve the above object in the strainer to discharge rainwater and remove the contaminants, it is mounted to the rainwater inlet and the outlet is formed in the center; A filter plate formed around the bottom of the collection box at the outlet and formed with a plurality of through-holes so that the contaminants are caught in the rainwater flowing into the collection box and only rainwater is passed; A pair of shaft clasps formed on an outer bottom surface of the upper limb catcher and having shaft holes formed therein; A rod shaft having both ends rotatably inserted into the shaft fixing hole of the shaft clasp; The rod shaft has a shaft hole in the center so that the rod shaft can be inserted, the opening and closing door having an area that can completely cover the discharge port to open and close the discharge port on one side based on the body, the open door on the other side of the body By rotating the rod shaft by the axis and the opening and closing hole made of a weight that can be returned when the external force is removed; provides an excellent strain screen for preventing bad smell, characterized in that it comprises a.

When the filter plate is installed on the bottom of the collection box, it is fastened in a state in which a plurality of spacers are formed on the bottom to be spaced apart from the bottom by 1 to 2 mm, and the opening and closing port is vertical as well as the horizontal direction of the discharge port. Characterized in that it can be installed in the direction, the upper surface of the opening and closing door is characterized in that the cushion member is further formed so that the watertight is maintained when in close contact with the outlet, the through-hole formed in the filter plate is at the bottom of the sump box Even though some of the through holes are blocked by the stacked composites, some of the through holes are formed so that the size of the through holes is gradually increased, so that the through holes are formed. It is characterized in that the smaller particles of fine particles can be stacked up to the point where the holes are formed.

According to the present invention, since the filter plate is not formed horizontally at the bottom of the collection box and is formed upright, even if a small amount is mixed with the contaminants, even if a small amount is stacked, the blockage is not blocked until the upper part of the filter plate is blocked. Rainwater can be drained by minimizing it, and the through-holes formed in the filter plate are formed larger and larger as they go from the bottom to the top, thereby preventing flooding even when the amount of rainwater is increased.

In addition, there is a gap of about 1 to 2 mm between the bottom of the collection box and the filter plate, so that the rainwater is allowed to infiltrate and escape therebetween, thereby preventing the decay of organic matter that proceeds after the inflow stops. Backflow odors are blocked by small amounts of soil or sediment.

In addition, the opening and closing doors that block the outlet opening and closing by using a weight to open and close the damping force is reduced than the opening and closing using a spring, the structure is simpler, the reliability of the device is high and there is almost no breakdown management costs can be greatly reduced.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 2 and 3, the collection box 100 is provided which is seated in the storm inlet of the storm receiver. The collection box has a space of about 20 × 30 × 20 cm in height to collect and drain a considerable amount of rainwater. The size of the collection box 100 is determined according to the amount of drainage depending on the situation or the degree of precipitation around the rainwater receiver. Collector 100 is generally manufactured by riveting or welding only the joining portion after bending the metal plate, but the welding part is oxidized when welding, it is preferable to combine the plate with a rivet (R) to slightly overlap the plate. Do. The upper end of the collection box 100 is formed with a flange 110 extending outward along the outer periphery so that it can be seated in a state spanning the collection box.

In the center of the collection box 100, a discharge port 120 having a width × length (8 × 16) is formed so that the rainwater flows in. The size of the outlet is also determined by the amount of drainage.

The filter plate 200 is formed to surround the bottom of the collection box on the outlet 120 to filter out contaminants from rainwater flowing into the collection box and to pass only rainwater.

The filter plate 200 is to be drained after the rain water is not drained directly to the discharge port, and caught the contaminants, it can be formed to a height of about 2/3 of the depth of the catchment, it can be added or subtracted as needed. In the collection box 100, various organic matters such as deciduous leaves, earth and sand, dogs and cats, etc. are introduced, and if they are kept with moisture, they are decayed, and the organic matters are mixed in the soil. Can't. Therefore, in the present invention, the separation plate 200 is not formed in close contact with the bottom, and the spacer member 200 having a thickness of about 1 to 3 mm is formed therebetween. do.

At the bottom of the filter plate 200 to form a folding portion 202 extending about 1cm outward along the outer circumference for convenience when fixed to the bottom of the collection box 100 to be firmly coupled by riveting it. Spacer member 220 may be formed in a plurality of at a predetermined interval on the bottom of the collection box, but the more the more formed it is to block the flow path is preferably formed only in the corner portion of the filter plate 200.

In general, the through hole 210 formed in the filter plate 200 is for removing a contaminant having a predetermined size (diameter of the through hole) mixed with rainwater, and when the diameter of the through hole 210 is small, the removal of the contaminant is easy. Influenced by the amount of drainage, if the diameter of the through hole 210 is large, the drainage of the rain water is good, on the contrary, contaminants with large particles also escape, causing the drainage pipe to be blocked. That is, the size of the through hole 210 is difficult to determine the size because of the relative amount of drainage and removal of impurities. In the present invention, the size of the through-hole 210 is relatively small in the lower part of the filter plate 200, and formed larger and larger as the upper portion of the through-hole 210 is discharged while the contaminants are filtered out in the small through-hole 210 at the bottom when the amount of rainwater is small. And, when the small through-hole 210 is blocked or there is a lot of rainwater inflow risk of overflowing the large through-holes 210 of the upper to be discharged while hanging. Since the primary purpose of storm drains is to drain rainwater without flooding, it is intended to maintain the drainage function smoothly even if small particles of contaminants spill into some drainpipes.

A pair of shaft clasps 410 are formed on the outer bottom of the collection box 100 to face each other. Shaft latch 410 is for mounting the opening and closing port 300 to be described later, the shaft fixing hole 412 is formed in the center. The rod shaft 400 is inserted into the shaft fixing hole 412 of the shaft clasp 410 so that both ends of the rod shaft 400 are inserted into the shaft fixing hole 412 to be freely rotatable.

The lower portion of the outlet 120 is provided with an opening and closing port 300 for opening and closing the outlet. The opening and closing port 300 is coupled to one side of the body 310, the body 310, the shaft hole 312 is formed so that the rod shaft 400 is inserted through, the outlet 120 to completely block the outlet 120 Rather than the dog door 320 having a slightly larger area, the other side of the body 310 is coupled to the other side of the rod shaft 400, the weight weight 330 so that the rotational force is always applied only in one direction. ) That is, the weight 330 rotates the opening / closing door 310 in a clockwise direction. The water pressure is applied to the opening / closing door 310 to rotate counterclockwise, and when the action of the hydraulic pressure (external force) disappears, the clockwise direction is caused by gravity. Rotated to the original position.

The weight 330 is formed to be inclined approximately 45 degrees to the horizontal line of the opening and closing door 310, which is when the opening and closing door 310 is rotated clockwise, until the weight 330 is interlocked 45 degrees The collection box 100 is to prevent the interference with the bottom. The larger the angle of inclination between the horizontal line of the opening and closing door 310 and the weight 330, the greater the weight of the weight 330 is rotated without interfering with the bottom surface of the collection box 100, so that the amount of drainage can be increased. Since the rotational force applied to the opening / closing door 310 is sharply reduced and the rotational force is not applied at 90 °, the inclination angle between the open door 310 and the weight 330 is preferably 30 to 60 °. Even if the angle between the opening and closing door 310 and the weight 330 is 90 degrees, when the clockwise rotation with the opening and closing door 310 is applied to the opening and closing door 310 because the weight 330 is interlocked to move up. However, since the rotation force is not applied when the opening / closing door 310 is completely in the original position, a gap is generated because the adhesion force between the outlet 120 and the upper surface of the opening / closing door 310 is reduced, and the gap is a passage through which the odor flows back through the drain pipe. It must be.

A cushioning member (not shown) may be formed on the upper surface of the opening / closing door 310 so as to increase the adhesion and to contact the collection container so that a gap does not occur. The cushion member may be formed only on a part of the opening / closing door 310, and thus may be formed on the entire upper surface of the upper and lower surfaces when the single layer is formed.

As the weight (330) is separated from the body 310, the longer the (width), the greater the rotational force, so that the weight can be reduced and the material cost can be reduced, but if the width is wider than protruding more than necessary outside the collection box 100 Since it may interfere with the component, it is preferable to set the length in consideration of the bottom width of the collection box 100.

The opening and closing port 300 is installed in the horizontal direction (length direction) of the collection box 100, but can also be installed in the vertical direction. Shaft shackle 410 is formed to face in the longitudinal direction, and coupled to the opening opening 300 to it, but protrudes more than the collection box 100 than the opening and closing port 300 installed in the horizontal direction, It may be selected depending on the installation location or type.

Referring to the operation of the excellent receiving sieve according to the present invention configured as described above are as follows.

4 and 5, in the state coupled to the opening and closing port 300 to the shaft clasp 410, the collection box 100 is seated in the rain inlet of the rain receiver.

When rainwater enters the catchment box 100 through the rainwater inlet, rainwater mixed with contaminants accumulates on the bottom of the catchment box 100, and when rainwater is accumulated, rainwater flows through the through hole 210 of the filter plate 200. The opening and closing door 310 blocking the) is discharged while being rotated counterclockwise by receiving water pressure. At this time, the weight 330 is interlocked and rotated, the opening and closing door 310 is opened until contact with the bottom surface of the collection box (100).

When the rainwater introduced into the collection box 100 is exhausted and the water pressure (external force) does not act, the outlet 120 is closed by being rotated clockwise by the weight 330. Opening and closing door 310 is opened by the action of a certain amount of water pressure is closed because a small amount of rain water is left, and for this reason, the impurities containing moisture will decay over time even if rain water is no longer introduced. Rainwater is most often introduced with a small amount of good soil absorption, so the evaporation of water is not well promoted, the corruption is further promoted, a gap of about 1 ~ 2mm formed between the bottom of the collecting container (100) and the filter plate (200) Residual rainwater escapes the furnace so that water is removed to prevent corruption. The gap may flow back through the odor through the drainage pipe, but a small amount of soil and small particles of small particles are blocked to prevent the reverse flow.

If the inflow of rainwater to the collection box 100 increases or the small through-hole 210 of the bottom is blocked by the contaminants, it may overflow, but the through-hole 210 formed in the filter plate 200 becomes larger and larger as it goes up. By this, the phenomenon that the filter plate 200 is blocked can be delayed for a long time. Rain filter for the rain net is cleaned periodically so that the impurities are stacked and can be removed before it completely fills up the filter plate 200.

Figure 6 is another embodiment of the present invention, the through hole 210 formed in the filter plate 200 is formed only a predetermined height without forming from the bottom. That is, when expressed as a fraction, it can be formed from a quarter point of the height of the filter plate, formed from 2/4 points, or formed from 3/4 points.

If the through-hole is formed only on the upper part of the filter board, even if a contaminant such as soil and sand having a smaller particle size than the through-flow that flows with the rainwater flows in, it is stacked up to the position where the through-hole is formed and is not discharged into the drain pipe. Clean. In this way, even small particles of debris are not discharged into the drain pipe so that the drain pipe is not blocked. The general drain pipe is hardly clogged even if the contaminants are mixed, but it can be selectively used according to the site situation since it may be blocked in the small diameter pipe or the old drain pipe.
