Description

[0001] The present invention relates to a dust separator for a pump and pump gate,

More particularly, the present invention relates to a pump damper for effectively preventing a suction port of a pump from being clogged by foreign substances such as sludge or impurities, and a pump damper for a pump To a pump gate integrally provided.

Generally, the water gate is a repair facility installed in drainage, irrigation waterway for agricultural use, irrigation water in contact with other rivers, and other drainage. Such a water gate is controlled by selectively opening and closing to control the flow rate, And also functions to prevent backflow of water due to flood or the like.

These water gates are normally opened, and the water is drained off to the outside water side (downstream side) on the domestic water side (downstream side), and rainfall increases due to heavy rain due to the weather change or rainy season, If the water level is higher than the domestic water level (inside water level), the water gate will be lowered and closed to prevent backflow of water.

However, when the gates are closed, the domestic water is blocked by the discharge passage, and the water level is gradually increased, thereby causing flooding damage in houses and farmland.

Therefore, a pump gate equipped with a pump at the water gate is used as a means for forcibly discharging the domestic water which is raised in the descending or closed state of the water gate without backward flow of the external water.

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

The conventional pump gate shown in the drawing includes a water gate 1 which is vertically moved up and down by a winch 6 to open and close a water channel and a water pump 1 which is provided in the water gate 1 and forcibly drains water on the water- And a pump 3 for supplying the water.

In the conventional pump gate constructed as described above, when the water level is higher than the external water level, the water gate 1 is raised to the winch 6 to drain the water to the external water side. When the water on the external water side suddenly increases due to flood, The pump 3 is operated in a state in which the pump 1 is shut off to discharge water on the water-side to the outside. In this case, however, when the pump (3) is operated, foreign materials such as wood, grass, household waste or farming waste, vinyls, and sludge block the inlet of the pump or enter the pump.

Accordingly, as shown in FIG. 1, a damper 9 for removing contaminants, sludge and the like is installed in front of the water gate 1 in order to solve this problem. A dust remover is a mechanical device that uses power to cut off foreign substances flowing along the water after screening it.

The conventional vibration damper 9 shown in FIG. 1 not only operates when the pump is operated by shutting off the water gate, but also causes the flow of the water to be caught by the screen bar of the damper, even when the pump is not operated by opening the water gate. There is a problem that the vibration damper must be continuously operated.

Therefore, wasteful manpower, power consumption, and additional costs are caused in the management of the dust collector. In addition, since damage and durability deteriorate due to operation of the damper for a long period of time, the damper needs to be replaced by removing water from the water channel for repairing damage or replacing damaged parts after removal of the entire damper, .

There is also a vibration damper attached to the pump suction pipe. However, in the conventional pump type vibration damper, when the screen is fixed and the foreign substance is filtered, the rake reciprocates or rotates while removing the foreign substances adhered to the screen. There is a problem in that if the efficiency is low and the foreign matter is caught between the screen and the rake, the motor tends to fail, and in the case of reciprocating motion, the driving motor must be rotated in the forward and reverse directions.

It is an object of the present invention to provide a pump damper which can effectively prevent clogging of a suction port of a pump due to foreign matter such as sludge or impurities.

Specifically, in order to compensate for the disadvantages of the conventional vibration damper in which the screen is fixed and the rake is reciprocated between the screens, in contrast to the conventional method, the screen rotates and the rake is fixed, that is, the spherical screen rotates If the foreign matter on the screen is transferred from one side of the pump inlet to the other side, foreign substances are caught on the rake fixed between the screens, allowing the pump to be pumped smoothly, and the foreign substances caught on the rotating screen are continuously filtered. , There is no risk of foreign matter getting caught on the screen and the rake, and rotation motions are performed only in one direction, thereby preventing the driving motor from being broken.

It is another object of the present invention to provide a dust collecting apparatus and a dust collecting apparatus which can prevent a suction port of a pump from being clogged by foreign matter without providing a separate dust collecting unit in front of a water gate by integrally providing a dust collecting unit in a water gate where a pump is installed, And which can be repaired outside of the water, so that the pump gate can be easily managed.

In order to accomplish the above object, the pump damper of the present invention is installed at the suction port of the suction pipe to prevent foreign matter from flowing into the suction pipe of the pump when the pump for discharging water is operated, A spherical screen portion spaced apart at a predetermined interval so as to allow an inflow gap to pass therethrough; And a rake installed in the inflow gap of the screen unit to remove foreign matter caught on the rotating screen unit.

More specifically, the screen unit is connected to an end of the suction pipe, and a plurality of circular plates having different diameters are disposed at a front end of the suction pipe. The circular plate has a shape of a sphere whose diameter decreases from the center of the suction pipe And forms an inflow gap, rotates in accordance with rotation of a rotary shaft welded and fixed through the center of each circular plate, and serves to filter foreign matter from the inlet so as to prevent foreign matter from flowing into the pump when the pump is operated. Is provided at one end of the suction pipe or another support and is positioned between the middle of the spherical screen inflow gap and scraping off the transferred foreign matter on the screen unit.

In order to accomplish the above object, the present invention provides a damper integrated pump gate comprising: a water gate opening / closing a water channel; A pump installed at the water gate for discharging water; A spherical screen unit installed at a suction port of the suction pipe to prevent foreign matter from flowing into the suction pipe of the pump and having the inflow gap to allow water to pass therethrough; A rake for releasing foreign matter caught on the screen unit when the screen unit rotates and transfers the foreign matter caught on the screen unit from one side to the other side; .

As described above, according to the present invention, it is possible to effectively prevent the suction port of the pump from being clogged by foreign matter such as sludge or impurities.

Compared with a conventional damper that fixes a screen and removes foreign matter caught on the screen while rake is rotating or rotating, the efficiency of the motor is improved because the screen rotates continuously to remove foreign substances, There is little fear of failure.

In addition, when the foreign substance is not sufficiently removed because the width of the conventional screen is not thick (about 7 to 8 cm), the screen may be rolled due to the difference in head inside and outside of the screen. However, Because it is a radius, the screen is bent by the water pressure and it is hardly broken.

In addition, it is not necessary to install a separate damper in front of the water gate because the damper installed at the water gate where the pump is installed can be integrally provided. Therefore, the civil engineering and construction cost for installing the damper in the water channel is greatly reduced. In addition, since it is integrated with the water gate, foreign matter such as sludge can be discharged naturally to the outside water side when the water gate is opened.

In addition, when the watercraft is opened, the operation of the vibration damper is not required, the maintenance is possible outside the water, and the maintenance is easy, and the vibration damper can be installed in various forms.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a damper-integrated pump gate according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 shows a pump gate in which a damper is integrally provided.

Referring to FIG. 2, the damper-integrated pump gate includes a gate 10, a pump 20, and a damper.

The water gate (10) is installed in the water drainage, agricultural water channel, and opens and closes the water channel. The water gate 10 opens and closes the water channel by opening and closing means not shown.

The water gate 10 controls the flow rate by selectively opening and closing the water flow, maintains the water depth, and functions to prevent backflow of water due to flood or the like. For example, water is drained to the outside water side (downstream side) on the domestic water side in the state where the water gate is normally open, and rainfall increases due to heavy rain due to the weather change or rainy season, (Outside water level) is higher than the domestic water level (inside water level), the water gate is lowered to block the water channel to prevent water backflow.

A pump 20 capable of pumping water is installed in the water gate 10 to forcibly drain the water-side water to the outside water in a state where the water gate 10 is lowered and the water channel is cut off. An underwater pump may be applied to the pump 20. The above-mentioned hydrological gate and pump are the same as the conventional structure shown in Fig.

In this embodiment, the damper is installed integrally with the gate 10. The damper integrally formed with the pump combined with the water gate 10 can move out of the water in accordance with the upward and downward movement of the water gate. This has the advantage of being easy to repair, and capable of discharging foreign matter such as sludge when the watercraft is opened.

Referring to FIGS. 3 and 4, the vibration damper of the present invention will be described in detail. The vibration damper includes, for example, a spherical screen unit 30 installed at a suction port of a suction pipe 21 to prevent foreign matter from entering into a suction pipe of a pump, And a rake 60 for removing foreign matters caught on the screen unit 30. [

At the open front end of the suction pipe 21, a plurality of circular plates 35 are installed. In the illustrated example, the circular plates 35 are spaced up and down at regular intervals. The circular plates 35 are formed to have different diameters and are horizontally or vertically arranged in a shape of a sphere so that the diameter gradually decreases from the center of the suction pipe 21 toward the upper side and the lower side. It is of course also possible to form the cylindrical screen portion 30 by disposing the circular plates 35 having the same diameter as the case may be. The distance between the circular plates 35 can be appropriately adjusted in consideration of the size of the foreign matter to be prevented from flowing and the suction force of the pump. The circular plates 35 are pierced by the rotational axis of the driving part and welded or bolted to the rotational axis.

Circular plates 35 are disposed apart from each other so that an inflow gap 37 through which water can flow is formed between the circular plates 35. The circular plates 35 are formed in the shape of a round sphere, with the plates 35 having small diameters gradually positioned upward and downward with respect to the center of the suction pipe 21.

Foreign matter larger than the inflow gap 37 is caught by the screen unit 30 to block the inflow gap 37 while the internal water is introduced into the suction pipe 21 when the pump 20 is operated.

The screen unit 30 includes a driving unit 40 installed in the water gate 10 and a rotating unit 50 connected to the driving unit 40 to receive power from the driving unit 40. The screen unit 30 rotates when the rotating shaft 50 rotates 30 for releasing the foreign matter transferred from the screen unit 30. [0050] As shown in FIG.

The rake 60 is disposed between the middle of each circular plate 35 forming the screen portion 30 such that one end is located between the two circular plates 35 so as to be close to the rotary shaft 21 and another end When the foreign substance is moved in the opposite direction from one direction of the suction port by the screen unit 30 which is fixed to the suction pipe 21 or another supporting unit so as to be exposed to the outside from the spherical screen unit 30 by a predetermined length, The foreign object transferred from the screen unit 30 is released.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention. . Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
