Dust separator for pump and pump gate of one body type having dust separator}

The present invention relates to a pump damper and a damper-integrated pump gate using the same, and more particularly, a pump damper and a hydrostatic damper integrally prevent water from being blocked by foreign substances such as sludge or contaminants. It relates to a pump gate provided.

In general, a hydrological gate is a repair facility installed in drainage, water and sewage, urban sewage treatment plant, water treatment plant, agricultural irrigation canal and other rivers, or other drains. It functions to regulate the flow rate, maintain the depth of water, and prevent backflow of water due to flooding and the like.

These flood gates usually drain the inland (upstream) water to the outflow (downstream) in an open state, and the rainfall increases due to heavy rainfall or rainy season due to weather changes. If the external water level rises above the internal water level (water level), the water gate is lowered and closed to prevent the reverse flow of water.

However, when the gate is closed, the water on the side of the water is blocked by the drainage path, which gradually raises the water level, causing flooding damage to houses and farmland.

Therefore, a pump gate having a pump installed in the water gate is used as a method for forcibly discharging domestic water rising in the closed and closed state without the backflow of external water.

1 is a view showing an example of a conventional pump gate.

Hereinafter, a vibration suppressor integrated pump gate according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 illustrate a pump gate in which a vibration damper is integrally installed.

2 and 3, the vibration suppressor integrated pump gate includes a water gate 10, a pump 20, and a vibration suppressor.

The water gate 10 is installed in a drainage station, a water supply and sewage system, an urban sewage treatment plant, a water treatment plant, an agricultural water channel, and the like to open and close the water channel. The sluice gate 10 opens and closes the waterway by opening and closing means (not shown). As an example of the opening and closing means may be applied to a winch for operating the handle or the driving motor to move the water gate up and down. The winch machine moves the water gate 10 up and down to open and close the waterway. And the water gate 10 is provided with rollers that can slide along the guide rail.

The sluice gate 10 functions to control the flow rate by selective opening and closing, to maintain the depth of water as well as to prevent the backflow of water due to flooding and the like. For example, water is usually drained to the outflow side (downstream) with the floodgates open, and the rainfall increases due to heavy rainfall or rainy season due to weather changes. If the (outside water level) rises above the inland water level (inner water level), the water gate is lowered to block the waterway to prevent backflow of water.

In the state where the water gate 10 is lowered to block the waterway, a pump 20 capable of pumping water to forcibly drain water to the external water side is installed in the water gate 10. An underwater pump may be applied to the pump 20.

The pump 20 is installed at a certain height at the bottom of the sluice 10. The pump 20 is installed through the water gate 10. The suction pipe 21 and the discharge pipe 25 are respectively coupled to both ends of the casing of the pump 20. The discharge pipe 25 is provided with a non-return valve to prevent the external water side from flowing back to the internal water side. The above-described water gate and pump are identical to the conventional structure shown in FIG.

In this embodiment, the vibration suppressor is integrally installed with the water gate 10. The vibration suppressor formed integrally with the water gate 10 may move out of the water according to the vertical movement of the water gate. This has the advantage of being easy to repair, the discharge of foreign matter such as sludge when opening the water gate.

The illustrated vibration suppressor includes, for example, a screen unit 30 installed at the suction port of the suction tube 21 to prevent the inflow of foreign substances into the suction tube of the pump, and a foreign substance removal unit for removing the foreign substances caught by the screen unit 30. .

In order to prevent foreign substances such as wood, grass, household or agricultural waste, contaminants such as vinyl, sludge, and the like, from entering the suction pipe 21 when the pump 20 installed in the water gate 10 is operated, the suction pipe 21 is suction pipe. It is installed in 21.

The screen unit 30 includes, for example, a shroud 31 coupled to an end of the suction pipe 21 and ribs 35 provided at the front end of the shroud 31.

The shroud 31 has a cylindrical structure in which the front and rear surfaces are open. Preferably the shroud 31 is formed larger than the diameter of the suction pipe (21). For example, when the diameter of the suction pipe 21 is 1000mm, the diameter of the shroud 31 may be formed to 1200mm. This is to prevent the suction force is reduced by reducing the suction space by the screen unit 30 installed in the suction pipe 21.

An open front end of the shroud 31 is coupled to the annular fixing frame 33. Fixing frame 33 may be mounted to the shroud 31 by a coupling member such as a screw or bolt.

The fixed frame 33 is provided with a plurality of ribs (35). In the example shown, the ribs 35 are arranged at regular intervals up and down. The distance between the ribs 35 may be appropriately adjusted in consideration of the size of the foreign matter, suction force, etc. to prevent the inflow. The ribs 35 may be fixed by welding to the fixed frame 33.

Since the ribs 35 are spaced apart from each other, an inflow gap 37 through which the water can flow is formed between the ribs 35. The ribs 35 are formed in an arc shape which is convex downward. The ribs 35 are positioned on a rotational track about the rotation axis 50 to be described later. Therefore, the curvature of each rib 35 is the same. In addition, the curvature of the rib 35 has the same curvature as the rotational trajectory of the removal protrusion 65 which will be described later.

As water flows into the suction pipe 21 when the pump 20 is operated, foreign matter larger than the inflow gap 37 is caught by the screen part 30 to block the inflow gap 37.

The foreign substance removal unit is installed in the water gate 10 to remove the foreign substances caught in the screen portion 30 while moving along the inlet gap 37 of the screen portion 30.

The foreign material removal unit is connected to the driving unit 40 installed on the water gate 10, the rotating shaft 50 receiving power from the driving unit 40, and the rotating shaft 50, and the screen unit moves while rotating the rotating shaft 50. The rake 60 which separates the foreign matter from the 30 is provided.

The driving unit 40 is for generating power and transmitting power to the rotating shaft 50. The driving unit 40 includes an electric motor 41 and a driving shaft 43. It is preferable to install the electric motor 41 on the upper end of the water gate 10 located outside the water. As the electric motor 41, an electric motor can be used. Preferably, a geared motor in which the electric motor and the reduction gear are combined into one is used.

The drive shaft 43 is connected to the electric motor 41 and extends downward. The drive shaft 43 is installed on the front of the water gate 10. The drive shaft 43 is supported to be rotatable by the bearing unit of the support member 45 installed in the water gate 10. The support member 45 is installed a plurality at regular intervals.

The rotary shaft 50 is connected to the drive shaft 43 serves to transmit power to the rake 60. The rotary shaft 50 is spaced apart from the suction pipe 21 and installed in parallel with the suction pipe 21. The drive shaft 43 and the rotation shaft 50 are connected by the joint member. Since the drive shaft 43 and the rotation shaft 50 are perpendicular to each other, the joint member is coupled to the first bevel gear 47 coupled to the drive shaft 43 and the rotation shaft 50 to engage with the first bevel gear 47. And a second bevel gear 57.

The rotating shaft 50 is formed such that the front end portion protrudes further forward than the suction pipe 21. The rotating shaft 50 is rotatably supported by the bearing unit of the support member 55 provided in the suction pipe 21 and the shroud 31, respectively.

The rake 60 is connected to the rotation shaft 50 to separate foreign matter from the screen unit 30.

The rake 60 includes a support bar 61 connected to the rotation shaft 50 to rotate about the rotation shaft 50, and a plurality of removal protrusions 65 installed on the support bar 61.

One end of the support bar 61 is coupled to the rotation shaft 50 and the other end extends outward of the rotation shaft 50. The support bar 61 extends to form a right angle with the rotation shaft 50. The support bar 61 is formed larger than the diameter of the screen portion 30. The support bar 61 rotates about the rotation shaft 50 when the rotation shaft 50 is rotated. Therefore, the support bar 61 moves across the front of the screen unit 60.

Removal projections 65 are installed in the support bar 61 a plurality at regular intervals. The removing protrusion 65 has a rectangular plate structure having a constant thickness. Unlike this, the removal projections 65 may be formed in various shapes and sizes, such as rod-shaped. When the support bar 61 is located in front of the screen unit 30, each removal protrusion 65 is disposed at a position corresponding to the inflow gap 37 of the screen unit 30. That is, one removal protrusion 65 is positioned between two ribs 35 adjacent to each other. Therefore, one side of the removal protrusion 65 is inserted into the inlet gap 37.

The above-described rake 60 is rotated about the rotating shaft 50 while the removal protrusion 65 moves along the inlet gap 37. By appropriate control of the electric motor 41, the rotation shaft 50 can rotate 360 degrees in either the clockwise or counterclockwise direction. In addition, as shown in FIG. 3, the rotation shaft 50 may rotate alternately in a clockwise or counterclockwise direction within a predetermined angle range. That is, the rake 60 alternately moves in the left and right directions about the screen portion 30 like a watch weight. At this time, the removal protrusion 65 of the rake moves from side to side along the inlet gap 37 to separate the foreign matter caught in the screen portion 30 from the screen portion 30.

Another embodiment of the rake is shown in FIGS. Referring to FIGS. 7 to 9, the rake 200 is connected to the rotation shaft 50 to support the support shaft 210 rotating around the rotation shaft 50, and a plurality of removal protrusions 220 installed on the support bar 210. ).

In the illustrated example, the removal protrusion 220 is not a structure fixed to the support bar 210, but has a structure in which the removal protrusion 220 can rotate within a predetermined range about the support bar 210. To this end, first and second catching jaws 221 and 223 are formed at positions facing each other on inner surfaces of the through holes formed in the removing protrusion 220, respectively. The first catching jaw 221 is formed to protrude on one side of the inner surface of the through hole. The second catching jaw 223 is formed to protrude from the inner surface of the through hole, which is opposite to the first catching jaw 221.

In addition, the support bar 210 has a first stopper 211 or a first stopper 211 that is caught with the first catching jaw 221 or the second catching jaw 223 during the rotation of the removing protrusion 220 to limit the rotation range of the removing protrusion 220. And a second stopper 213 is formed. The first stopper is formed in a fan shape on one side of the outer circumferential surface of the support bar 210. The second stopper is formed in a fan shape symmetrical with the first stopper 211 on the opposite side of the first stopper 211.

The first catching jaw and the second catching jaw 221 and 223 are disposed between the first stopper 211 and the second stopper 213, respectively. Empty space between the first and second locking jaws 211 and 213 and the first and second stoppers 221 and 223 in a state where the support bar 210 is inserted into and coupled to the through hole of the removal protrusion 220. As much as removing projection 220 may be rotated to a certain range from side to side. The rotation range is preferably within the range of 60 to 120 degrees.

Looking at the operating state of the rake having the above-described structure, as shown in Figure 9, the removal projections 220 of the rake 200 proceeds in an obliquely inclined state at the A position. This is because foreign matters caught on the ribs 35 of the screen part act as a load on the front end of the removal protrusion 220. When the rake 200 proceeds to the B position, the rear end of the removal protrusion 220 is gradually caught while being caught by the inner surface of the shroud 31. When the rake 200 reaches the C position, the removing protrusion 220 is positioned straightly, and when the rake 200 proceeds to the D position, the front end of the removing protrusion 220 rotates outward of the shroud 31. While inclined. This has the effect of flipping the removal protrusion 220 in the outward direction of the shroud 31 can effectively shake off the foreign matter buried in the removal protrusion 220. On the other hand, when the rake 200 reaches the D position, the motor of the drive unit rotates in the opposite direction to advance the rake 200 in the opposite direction. Reference numeral 7 is a foreign object caught in the rib.
