Description

Water jet nozzle for sludge collection of water purifying plant

The present invention relates to a collecting spray nozzle for collecting sludge impregnated on the bottom of a water tank of a water treatment plant and a sewage treatment plant. More specifically, the sludge is sprayed through a collecting spray nozzle which is moved on a rail installed at an upper portion of a water tank. Water to the end of the tank, but by repeatedly rotating the injection nozzle in the forward / backward direction from the lower side, water is sprayed as if sweeping the floor with a broom, so that the sludge collection work smoothly and the sewage treatment plant Sludge collection injection nozzles.

In general, in a sedimentation tank or agglomeration tank such as a water purification plant or a water intake plant, suspended solids are precipitated by a specific gravity over time, and when a flocculant is administered to the flocculation tank, the aggregated solid sludge sinks to the bottom.

Water flowing in the sedimentation tank or flocculation tank has a very slow flow rate, and sludge contained in the water sinks to the bottom in the process of flowing water, and when the sludge is left for a long time, the sludge accumulated on the bottom surface of the water It solidifies in the state.

If the sludge solidified as described above is left for a long time, the contaminant generated from the sludge itself contaminates the water quality, and the sludge is decomposed to cause bad smell, and as the sludge is solidified, the cleaning operation is not performed properly, thereby improving the water quality. It became a contaminating factor.

Such a sedimentation tank or a coagulation tank is used to purify the water flowing from the water channel and to be used as general household, industrial, or agricultural water, and if the sedimentation tank or agglomeration tank is contaminated, there is no doubt that the water supplied is contaminated. When the contaminated water is used for home, industrial or agricultural use, it causes a fatal adverse effect.

As a means for removing sludge that has sunk in a sedimentation tank or agglomeration tank as described above for a long time, a chain of a caterpillar type that enters the roots is recommended, and when the chain is driven in a state where a scraper is installed at an appropriate interval on the chain, Devices are installed to collect the sludge sedimented in the sedimentation tank or flocculation tank by using a separate submersible cart or the like so that the sludge that is precipitated can be removed by the scraper.

However, in the sludge collection apparatuses used in the related art, in this case, as the transport means such as the chain is left in the water for a long time, corrosion occurs in itself, which shortens the service life, and is a link that is a means for connecting the chain. Corrosion occurred in the chain, causing chain short-circuit during use.

In addition, although the components are complicated, the installation cost is increased and the sludge that is deposited at the bottom of the tank is removed through the scraper moved by the chain, but the scraper function is deteriorated and the sludge is not completely removed. In addition, foreign materials such as stones, chips, bolts, etc. may damage the scraper or flight or cause a large accident in the sludge collector, making it impossible to collect the sludge.

Moreover, since the scraper must be replaced at any time, there is a problem such as an additional cost in replacement.

It consists of a wire pulley for winding the wire to lift the scraper, or to raise up vertically.

In the case of the prior art configured as described above, since the sludge deposited by the scraper for advancing and reversing the bottom of the tank is removed by the electric power of the electric motor as described above, the sludge is removed if the bottom surface is uneven or there is foreign matter. This is a situation that is impossible due to the problem of increasing the installation cost or replacement of the scraper.

The present invention has been made to solve the problem of the sludge collecting device for removing and collecting the sludge deposited on the bottom of the water tank of the conventional water purification plant or sewage treatment plant, the lower portion of the transfer unit moved along the rail installed on the upper side of the water tank Water is sprayed on the side or the fixed pipe further comprises a spray nozzle, in the process of moving the spray portion of the spray nozzle in the state of retreating to the rear side to move the front side while the water is sprayed as if using a broom In the same principle as using the bottom of the sludge, sludge is removed to facilitate the collection of sludge, and the simple construction is expected to reduce the installation cost and also eliminate unnecessary work such as scraper replacement work. As a result, usability is improved and maintenance costs are not incurred.

As shown, the sludge collection spray nozzles of the present water purification plant and sewage treatment plant are

The sludge deposited on the bottom of the tank is removed by the water sprayed by being attached to the lower side of the transfer part 103 or the fixed pipe which is moved forward and backward along the rail 102 installed on the upper side of the tank 101. The injection nozzle 100 is to be collected at the end of the water tank, the opening part 11 is cut open partly formed on the lower side and the partition wall 12 (13) on both sides of the opening (11) Is formed and the water jacket 14 is formed therein, the inner rotary body 20 which is constructed by the hinge rotating shaft 21 on the central side of the body 10, and the inner rotary body ( 20 and the injection portion 30 is eccentrically coupled to one side of the inner side is in communication with the water jacket 14 of the body 10, the forward and backward eccentric rotation within the range of the opening 11, and the inner rotation Eccentrically coupled to the other direction side of the whole 20 to the receiving portion 15 formed inside one side of the body 10 But the bucket portion 40 and the eccentric rotation in the same direction as the injection portion 30 at the time of the eccentric rotation of the injection portion 30 to restore the eccentric rotation injection portion 30 to its original position, and the bucket portion An elastic spring 50 for early restoring the eccentric pivoted bucket portion 40 to its original position at the time of the eccentric rotation of the 40 and a guide hole in which the protrusion 40a of the bucket portion 40 is interpolated and guided. 61 and an inflow passage 62 through which water is supplied to the inner side of the accommodating portion 15 and a drain passage 63 through which water introduced into the bucket portion 40 is drained.

When the sludge collection injection nozzle 100 of the present invention purified water and sewage treatment plants configured as described above is supplied with high pressure water into the water jacket 14, the high pressure water is in communication with the water jacket 14. High pressure sprayed through the injection unit 30 to remove the sludge deposited on the bottom of the water tank 101, wherein the bucket unit 40 is the axis of the rotation shaft 21 relative to the body 10 The eccentric rotation in the clockwise direction and thus the injection portion 30 is rotated eccentrically in the clockwise direction of the opening 11 so that the injection portion 30 as if using the broom to use the bottom of the water tank 101 ( 10) The sludge is easily removed since the high pressure water is injected and the sludge is removed while moving backward to the rear side.

The bucket portion 40, the inlet hole 41 through which the water flowing in through the inflow passage 62 flows in and the outlet hole 42 through which the inflowed water flows out correspondingly, respectively, and the inflow hole 41 One end is fastened by a bolt 44a to one surface of the housing 43 and a housing 43 in which water flowing through the housing is accommodated, and positioned inside the inlet hole 41 to open and close the inlet hole 41. A second check valve having a first check valve 44 and one end fastened by bolts 45a to the other surface of the housing 43 so as to be located inside the outlet hole 42 to open and close the outlet hole 42. It consists of a valve (45).

It describes the operation of the sludge collection injection nozzle of the present invention water purification plant and sewage treatment plant consisting of the above configuration.

A portion of the high pressure water supplied to the water jacket 14 is introduced into the inflow passage 62 formed at the upper portion of the body 10, and the water flows into the receiving portion 15 in communication with the inflow passage 62. When this flows in, the receiving portion 15 is filled with water.

When the water is filled in the container 15 as described above, the first check valve 44 of the bucket part 40 is moved toward the inner side of the bucket part 40 by the water pressure of the water filled in the container 15. Water that is filled in the receiving portion 15 through the inlet hole 41 while being pushed in flows into the housing 43 of the bucket portion 40.

In addition, when water flows into the housing 43 of the bucket part 40 and the water is filled in the housing 43, the bucket part 40 is clockwise of the body 10 by the pressure of water. Rotate eccentrically.

When the bucket part 40 is eccentrically rotated as described above, the spray part 30 which is eccentrically coupled to the inner rotating body 20 in which the bucket part 40 is eccentrically coupled to the other direction is also bucket part 40. By rotating in the clockwise direction which is the same rotational direction as the above, the injection unit 30 proceeds to the operation to retreat to the rear side of the body (10).

In addition, the injection portion 30, which is retracted toward the rear side of the body 10 in this way, the water filled in the bucket portion 40 is discharged through the drainage passage 63 to the bucket portion 40 As the pushing water pressure drops, the restoring force of the elastic spring 50 is actuated to restore the original position while eccentrically rotating counterclockwise with respect to the body 10.

That is, the bucket part 40 which is rotated in the clockwise direction by the water pressure pushed by the water filled in the bucket part 40, the projection is moved along the guide hole 61 formed in the body 10 When the 61 is positioned at the end of the guide hole 61, the movement of the protrusion 61 is stopped, and the outside of the second check valve 45 of the bucket part 40 is in contact with the stopped protrusion 61. While the second check valve 45 is pushed toward the inside of the bucket part 40, the outlet hole 42 in which the second check valve 45 is formed is opened to open the bucket part through the open outlet hole 42. Since the water filled in the 40 flows out and is drained out of the body 10 through the drainage passage 63, the pushing force of the water acting inside the bucket part 40 is released and connected to the bucket part 40. The bucket portion 40 is rotated to the original position by the elastic spring 50.

Therefore, when the bucket part 40 is rotated to its original position, the injection part 30 which is eccentrically coupled in one direction of the inner rotating body 20 also rotates eccentrically toward the front side of the body 10 which is the original position. At this time, the high pressure water supplied by the water jacket 14 is sprayed at a high pressure through the spray unit 30 to remove the sludge that is deposited at the bottom of the tank.

In this way, the sludge impregnated at the bottom of the tank is removed by the high pressure injection of water injected by the retreat and advancement of the injection part 30, and the sludge is removed by sweeping the bottom of the tank using a broom. , Sludge is easily removed without remaining foreign substances such as stones, bolts, and chips in the sludge.

Retraction and advancement of the injection portion 30 is made in the inner range of the opening 11 cut in the lower side of the body 10, when retreating the partition wall formed on one side of the opening (11) ( 12) is interfered by the barrier rib 13 formed on the other side of the opening 11 when moving forward, so that a constant retreat and forward can be made at all times, so that an operation such as using the broom to use the floor is uniform. It is easy to remove the sludge.

Inside the first check valve 44 and the second check valve 45 of the bucket part 40 to facilitate the opening and closing of the first check valve 44 and the second check valve 45 and to extend the life. The iron plate 46 may be further coupled, and the first check valve 44 or the second check valve 45 opened by the weight of the iron plate 46 may be more easily closed. The material of the check valve 44 and the second check valve 45 is not limited, but is preferably formed of a rubber material.

In addition, the bucket part 40 is a projection 40a which is formed on the upper side of the bucket part 40 is guided along the guide hole 61 through the body 10, so that the bucket part 40 Out of a certain range during the rotation is interfered, and when the bucket portion 40 rotates in the clockwise direction, if the projection 40a is in contact with the other end of the inside of the guide hole 61 of the bucket portion 40 The water accommodated therein is drained through the drainage passage 63. At this time, the restoring force of the stretched elastic spring 50 is applied, so that the bucket portion 40 is eccentrically rotated to its original position and thus the injection portion 30 ) Also rotates eccentrically to its original position.

Since the high pressure water is sprayed to the bottom of the tank while repeatedly performing such an operation, it is possible to neatly remove the sludge deposited on the bottom of the tank, thereby greatly improving the sludge removal efficiency.

The present invention is capable of various modifications in addition to those shown and described, all modifications are to be included in the scope of the present invention without departing from the scope of the present invention.
