Description

DUST SEPERATOR FOR SEWAGE AND WASTEWATER PUMPING STATION

The present invention relates to a damper for a sewage and wastewater pumping station, and more particularly, to a damper for a sewage and wastewater pumping station capable of removing contaminants flowing into a space between a screen and a waterway bottom.

In general, a vibration damper is a kind of mechanical device for removing impurities caught on a screen installed in a place where impurities are introduced, such as an inlet waterway of a sewage and wastewater pumping station by using power.

These vibration dampers are divided into various types according to their purpose and purpose.

In particular, efforts are being made to efficiently remove contaminants that are relatively heavy in weight, such as wood or stones, included in sewage and wastewater.

A conventional dust filter for sewage and wastewater pumping stations includes a main screen; Side frames installed on both sides of the main screen to support the main screen; A rake that is transported along the main screen to remove impurities caught on the main screen; Rear auxiliary screen installed at the rear of the lower side of the main screen to filter out impurities flowing between the main screen and the bottom of the waterway; It is supported by the side frame and is configured to include a cover screen that blocks the passage of impurities rising from the rear side of the main screen along the rear auxiliary screen.

Such a vibration damper for a sewage and wastewater pumping station is disclosed in Korean Patent Registration No. 10-1731933.

However, due to its constitutional characteristics, the above dust suppressor for sewage and wastewater pumping station can only filter the contaminants flowing between the main screen and the bottom of the waterway and smoothly and stably lift the contaminants caught in the rear auxiliary screen through the rake. There is a problem that it is difficult to do. For example, the situation in which the foreign matter is separated (departed) from the rake when lifting the foreign matter caught on the rear auxiliary screen through the rake frequently occurs.

In particular, this is especially true when removing heavy contaminants such as wood or stones.

In addition, when impurities are not stably lifted by the rake and are accumulated on the bottom of the waterway, there is a disadvantage in that the rake is damaged due to interference caused by impurities during the rotation of the rake.

This in turn results in lowering the functionality and usability of the dust collector for sewage and wastewater pumping stations.

The present invention has been devised to solve the above problems, and the problem to be solved in the present invention is a vibration damper for a sewage and wastewater pumping station capable of stably lifting contaminants flowing into the space between the screen and the waterway floor through the rake. is to provide.

Hereinafter, a vibration damper for a sewage and wastewater pumping station according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the vibration damper for a sewage and wastewater pumping station according to the present invention includes a pair of support frames 10; Chain conveyor 20 installed inside a pair of support frames 10; a screen 30 installed between a pair of support frames 10; a guide plate 40 installed on the lower rear side of the screen 30; A plurality of rakes 50 connected to the chain conveyor 20 and installed; It is configured to include an operating member 60 connected to the chain conveyor 20 .

A pair of support frames 10 are arranged to be spaced apart from each other and installed to stand on the waterway bottom (B, see FIG. 7 ).

The support frame 10 has a structure in which a lower end thereof is bent in a horizontal direction by a predetermined distance.

In addition, the support frame 10 is made of a metal material having excellent physical properties such as water resistance and durability, and its shape, size, or material can be appropriately changed as needed.

The chain conveyor 20 has a shape corresponding to the pair of support frames 10 . That is, the chain conveyor 20 is bent so that the lower end thereof is rounded in the horizontal direction by a predetermined distance, and is cyclically operated along the longitudinal direction of the support frame 10 by driving the operation member 60 .

In particular, the chain conveyor 20 is preferably cycled counterclockwise to smoothly remove and lift contaminants from the screen 30 through the rake 50 interlocked therewith.

The screen 30 serves to filter various contaminants contained in sewage and wastewater, and is composed of a plurality of blades that are vertically spaced apart from each other at regular intervals.

The screen 30 has a shape corresponding to the chain conveyor 20 , that is, the lower end thereof is formed to be rounded in the horizontal direction like the chain conveyor 20 .

On the other hand, as the screen 30, a variety of known types can be selectively applied.

The guide plate 40 guides various contaminants flowing into the space between the chain conveyor 20 and the waterway bottom surface (B) upward to implement the removal and lifting of contaminants through the rake 50 smoothly and stably. play a role In addition, when the guide plate 40 falls to the lower part without smooth transport of contaminants by the rake 50 due to an external shock or external environment, the fallen contaminants are not separated to the outside and on the guide plate 40 It enables re-transfer through the rake 50 to be located in the .

The guide plate 40 is detachably coupled to a pair of support frames 10 for easy replacement, and is made of a metal material having excellent physical properties such as water resistance.

And, as shown in FIGS. 3 and 4 , the guide plate 40 is formed to have a shape corresponding to the lower area of the screen 30 so that the cross section is rounded in a bow shape. Accordingly, it is possible to further enhance the removal efficiency of various contaminants introduced into the space between the chain conveyor 20 and the waterway bottom surface B, in particular, contaminants such as wood or stones, which are relatively heavy in weight.

In addition, in the guide plate 40, a plurality of hole-shaped drainage parts 42 for draining water except for various contaminants are formed in a predetermined pattern, and the shape, size, or arrangement of the drainage part 42 is Needless to say, it can be changed as shown in FIG. 5 if necessary.

On the other hand, in the guide plate 40, in addition to the drainage part 42, as shown in FIG. 6, when transporting various impurities through the rake 50, a roller to make the transport of impurities, such as wooden or stones, which are relatively heavy in weight, more smoothly. A transfer auxiliary part 44 of the structure may be additionally installed, and it is preferable that this transfer auxiliary part 44 is installed in the drainage part 42 . And although not shown separately in the drawing, an anti-friction coating layer (not shown) for smooth transport of wood or stones may be formed on the surface of the guide plate 40 , and various contaminants at both ends of the guide plate 40 . A departure prevention wing portion (not shown) that is bent upwardly so as to be guided stably without being separated to the outside may be formed.

For example, in the absence of the transfer auxiliary unit 44 , the transfer of foreign substances having a relatively heavy weight may not be smoothly performed, as well as damage to the rake 50 .

The rake 50 is made of a plate shape in which a plurality of rakes are formed along the longitudinal direction, and both ends thereof are connected to a pair of chain conveyors 20 and are interlocked according to the operation of the chain conveyor 20 to thereby screen 30 ) and serves to remove and lift various contaminants of the guide plate 40 .

In particular, the rake 50 is transported horizontally along the trajectory of the chain conveyor 20 from the lower end of the support frame 10 and is moved to the upper part while smoothly drawing a round curve. and can be hoisted stably.

And a cutter 52 such as a blade plate or a toothed plate may be additionally provided at the lower portion of the rake 50 as shown in FIG. 7, and when the rake 50 is operated through the cutter 52, such as It is possible to more efficiently remove various contaminants including

In addition, the rake 50 removes the resistance of the flow rate according to the movement in the water so that the movement direction in the water coincides with the flow direction of the water to minimize the power loss, that is, the circulation operation is counterclockwise. desirable. That is, the rake 50 is lowered in front of the chain conveyor 20, and the rake 50 is raised in the rear of the chain conveyor 20 so that the circulation operation is preferably made.

For example, when the moving direction of the rake 50 in water is opposite to the flow direction of the water, power loss occurs due to the resistance of the flow rate when the rake 50 moves in the water, as well as the screen 30 and the guide plate 40. There is a problem that it is not easy to remove contaminants.

The operation member 60 serves to cycle the chain conveyor 20 . As shown in FIG. 8, the operation member 60 includes a main motor 61; a reducer 62 connected to the main motor 61; a first sprocket 63 connected to the reducer 62; a second sprocket 65 connected to the first sprocket 63 by a connecting chain 64; A shaft 66 coupled to the second sprocket 65 to circulate the chain conveyor 20; a third sprocket 67 coupled to an end of the shaft 66; It consists of a third sprocket (37) and a fourth sprocket (69) connected by a connecting chain (68).

And the scraper brush 70 is for removing various contaminants caught on the rake 50, and is operated by the driving force of the main motor 61 for operating the chain conveyor 20 without a separate driving means. That is, the driving force of the main motor 61 is transmitted to the first sprocket 62 and the second sprocket 65 to rotate the shaft 66, and at the same time, the third sprocket 67 rotates and interlocks with it. As the fourth sprocket 68 rotates, the scraper brush 70 is operated.

At this time, the rotation speed of the scraper brush 70 is enabled by appropriate adjustment of the gear ratio.

In particular, the third sprocket 67 is provided with an encoder 80 for the reverse rotation operation of the rake 50, and the rake 50 is reversed when contaminants are caught in the screen 30 through this encoder 80. It can be rotated to remove contaminants.

For example, when a load is generated on the rake 50 due to jamming of contaminants, it is sensed in real time and the rake 50 is reversely rotated a certain distance through the encoder 80 to remove the load. And if a load is continuously generated even in the reverse rotation operation of the rake 50, the forward and reverse rotation operations of the rake 50 are repeatedly performed until the load is removed. In spite of this, if the load is not removed, the operation of the rake 50 is stopped after transmitting an error signal.

On the other hand, an unexplained reference numeral W denotes a sprocket wheel to which the chain conveyor 20 is coupled.

The operation state of the vibration damper for the sewage and wastewater pumping station described above will be described with reference to FIG. 9 as follows.

First, the rake 50 moves horizontally along the trajectory of the chain conveyor 20 installed on the inside of the support frame 10, and moves upward while gently drawing a round curve while moving the screen 30 and the guide plate ( 40) to remove and salvage various contaminants.

At this time, various contaminants of sewage and wastewater introduced into the space between the screen 30 and the waterway bottom surface B are naturally guided to the guide plate 40 located on the movement path, and guided to the guide plate 40 in this way. The collected impurities are lifted upward by the rake 50 .
