Description

Screen bar for damper screen {Screen bar of removing machine of dregs in water}

The present invention relates to an apparatus and a method for installing a low water level drainage pumping station, a water supply water intake pipe, a related water supply pipe, a sewage treatment plant, and a dam in an open channel to filter a floating water stream (floating garbage) And more particularly to a screen bar for a damper screen which is a unit component constituting a damper screen.

In recent years, various intake and drainage pumping stations have been enlarged to increase the water intake and drainage capacity. Also, sewage and stormwater pumping stations have been installed in many places according to progress of sewerage supply. In these water treatment plants, If there is contamination of dirt and garbage, it will cause damage to the pump or the pumping function to be considerably weakened, and these trash can block the repair channel, causing flooding due to inadequate drainage such as heavy rainfall. .

For this reason, a water damper is installed on the water line so that the water coming into the drain can not flow to the pump side together with the water stream, so that the flow of the water stream is smooth by filtering out the water and discharging it to the outside.

The apparatus disclosed in the official gazette of Registration Practical Utility Model No. 20-0175037 by the inventor of the present invention is installed in the middle of the drainage as described above to automatically filter the drainage water and discharge it to the outside.

1 and 2, a screen 11 formed at an angle to the bottom surface at an angle with respect to the bottom surface of the screen 11, And a screen 11 'for applying a screen to the screen 11 and a bottom surface 11' for screening the screens 11 and the screen 11 ' A driving motor 14 for driving the endless chain 16 so that the rake 13 continuously rotates on the screen 11 and a drive motor 14 for driving the endless chain 16, And guide rails 17 provided at the lower ends of both sides of the screen 11 to guide the rotation of the pump 16 when the water is sucked by the pump (not shown) The dyes are transferred to the screen (11) And is lifted up by a rake 13 rising along the chain 16, so that on the upper side of the apparatus, the projections are dropped onto the conveyor transfer device (not shown in the figure) and conveyed to the outside by the conveyor belt .

3, the screen 11 includes a plurality of diaphragms 11a installed at regular intervals and has a size equal to or larger than the interval L ₁ between the diaphragms 11a, The _first and the second ends of the rake 13 are separated from each other by the wedge action and are caught by the rear end portion between the diaphragms 11a. without diaphragm (11a) to be displayed is a problem that while the remaining sandwiched between, is the so-plate (11a) jingae water to wedged remaining between the (P ₁₎ blocking the gap between the plate (11a) water flow And it is difficult to process a large amount of water quickly due to a demand for a higher pump performance, which causes various problems such as a decrease in water throughput during floods and flooding.

In order to solve such a problem, the present inventor proposed a screen for a vibration damper through Korean Utility Model Publication No. 1991-0004759, and FIG. 4 shows the structure of the damper screen.

The screen 21 for the vibration suppressor is obtained by mounting a rod member 31 having a circular cross section and having an outer diameter d larger than the plate thickness t of the partition plate 21a at the tip of the partition plate 21a, 31) the distance between the between the (L ₂₎ between the plate (21a) smaller than the distance (L ₃₎ between the between the rod member (31) of size to pass between between jingae water-plate (21a) So that it can pass without being interposed.

However, when the rod members 31 are mounted at the distal ends of the respective diaphragms 21a, the rod members 31 act as resistances to the pump suction force, causing loss and lowering the flow velocity.

This is because the rod member 31 has a circular cross-sectional shape, which causes confusion in the flow path when the water vertically flowing in the front is struck at different points on the side surface (the principle that light is reflected in the convex mirror, ) Causing a vortex at the entrance of the screen, resulting in loss of fluid movement.

Therefore, in order to reduce the flow loss, it is necessary to make the flow as close to laminar flow as possible.

To this end, the present applicant has proposed a damper screen having an improved structure of a screen bar through Korean Patent No. 10-0949384.

As shown in FIG. 5, the improved damper screen is installed on the front portion of the damper so as to filter out water of a certain size or more contained in the water flowing along the waterway by the operation of the pump, and to allow water to pass therethrough (1), each of the screen diaphragms (1) having a leading edge line (3) extending in the direction of the fluid flow And the front slant surfaces 4a and 4b are extended to both sides so as to be symmetrical to each other from the front end edge line 3 to the rear side and the both front slant surfaces 4a and 4b are formed to be symmetrical with respect to each other, The diagonal distance T between both side edge corner lines 5a and 5b formed at the respective ends is larger than the thickness t of the screen diaphragm 1 and the diagonal line is larger (6a) and (6b) extending in the direction to approach each other from the opposite side edge lines (5a) and (5b) toward the rear, and are provided at the front end of each of the screen diaphragms The screen tip 2 is fixed to the screen diaphragm 1 by welding or integrally or separately formed.

The diamond-like structure of the screen tip 2 of the present invention as described above has a smaller resistance to the flow of water than the conventional diaphragm 11a and the structure of the rod member 31, Although it is effective due to the effect of reducing the flow loss, it is effective in the case of a thin and large tent that has come down with heavy rains in summer, tall vegetation such as waste vinyl, reed, and jellyfish screen installed on nuclear power plants and beach seawalls. (13) rises in all of the above-mentioned prior arts, when they are stuck to the surface of the screen and are strongly attracted to the surface of the screen by the suction force by the operation of the drain pump at the rear, And it is urgent to improve it.

That is, when the rake 3 (13) rises, a tent or the like sticking to the diaphragms 11a and 21a of the screens 11 and 21 is positioned between the screens 11 and 21, (See FIG. 4), which is projected in a waveform shape at the rear end of the rake 13 and is guided by a shallow depth between the diaphragms, is slid up on the surface of the tent, It is often the case that it can not be rolled up well, and the wide opening of the tent blocks the rapid drainage of the water due to strong adsorption resistance on the screen surface and also the tent is rolled up from the bottom to the top, There has been a problem that the motor 14 that drives the chain 16 that pulls the rake is exerted an excessive resistance and causes an overload to cause the motor 14 to fail.

In view of the above, the applicant of the present invention proposes a damper capable of cutting a dam body through Korean Patent No. 10-1157914. The damper device has a screen tip of a tip of each diaphragm forming a damper screen A roller receiving a pressing force by the elastic spring toward the tip blade side of the diamond body is rotatably disposed at an interval between the tip end of the diamond body and the tip end of the rake, The jellies of the jellyfish and seaweed trapped between the rotary roller and the rotary blade are cut off in cooperation with the leading edge when the roller is rotated while being raised.

However, since the screen tip is made of a sharp blade and the same metal-made roller always presses the blade, the friction of the sliding friction must be repeated, so that the blade is easily scratched due to abrasion, But it has a problem in that it is ineffective for the cutting process of a relatively thin thickness of a javelin such as a tent or a vinyl. Further, the installation structure of the cutting mechanism is complicated and the volume It is necessary to adjust the size and installation position so as not to interfere with passing through the potential screen area, but there is a problem that there are many design restrictions due to the limitation of the installation place on the upper surface of the rake.

Korean Registered Utility Model Publication No. 20-0175037 Korean Registered Utility Model Publication No. 1991-0004759 Korean Patent No. 10-0949384 Korean Patent No. 10-1157914

Accordingly, the present invention has been made in view of the foregoing points, and it is an object of the present invention to provide a tentacle, vinyl, tall grass, jellyfish, And prevents overload of the motor by preventing overload of the motor due to a failure of the motor and a wide screen adhered material and reduces the maintenance cost of the damper device.

In order to achieve the above-mentioned object, the present invention provides a dust collecting apparatus, which is installed in a front portion of a dust collector and which filters water of a certain size or more contained in the water flowing along the water path by the pump operation, And a screen tip having a size larger than the thickness of the screen diaphragm is formed at a front end of the screen diaphragm. The screen bar for a damper screen is characterized in that a sawtooth is formed at the tip of the screen tip .

According to the present invention, the screen tip has a diamond cross-sectional shape with a sharp tip or a circular cross-section or an elliptical cross-sectional shape.

According to a preferred embodiment of the present invention, the teeth are inclined toward the lower side so as to facilitate cutting of the nozzle.
