Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a scum collecting device capable of automatically tracking water level and scum collecting using buoyancy,

The present invention relates to a scum collecting device capable of automatic leveling and scum collecting using buoyancy. In collecting scum or scum generated in flocculating paper or sedimentation paper of a water purification plant, The present invention relates to a scum collecting device capable of automatically scooping up and down and collecting scum by injecting and discharging it into a buoyancy tank.

Generally, a water treatment plant is a water treatment facility for purifying raw water to make clean water, and the raw water is supplied to and discharged from a water purification unit consisting of a settling tank, a mixed tank having a chemical input unit and a forming sheet, a settling tank, a filter paper, and a water pump.

The wastewater treatment plant treats sewage from workplaces such as houses and factories. The wastewater is purified to about 92 ~ 95% through sedimentation basin, aeration tank, and final sedimentation basin and then sterilized and discharged into the river or sea have.

In addition, the sedimentation basin installed in a water purification plant or a sewage treatment plant removes surface deposits (flocs) using a sedimentation separating action. The sedimentation basin has a predetermined space and has an inlet, an outlet and a sludge A sludge removal facility, and a scum removal facility for removing floating flocs from the water.

On the other hand, the sludge removal facility is a device that scrapes sludge in a reverse direction by a scraper attached to an underwater truck and discharges the sludge to the outside, or drives a flight connected to a chain installed on the bottom of a sludge tank to flow the sludge in a reverse direction.

The scum removing device is installed to be fixed to the upper end of the inner wall of the settling basin in the horizontal direction, thereby removing floating matters floating on the water.

Generally, the cause of scum is a growing group of organisms that ingest carbonic acid gas and organic salts in the water and act as a photosynthetic agent, and it is widely distributed in an improved sedimentation basin, for example, a water purification plant or a sewage treatment plant, and provides scum generation.

In order to remove the scum in the water treatment process or the wastewater treatment process, an operation method of suppressing the generation of bubbles affecting the occurrence of scum is applied, or a method in which chemicals are injected and processed is used. The treatment efficiency is considerably low, and since it requires a small amount of expenses such as running costs and drug use costs, it is economically disadvantageous.

At present, the removal of scum is a gradual move from the past due to the manual operation, and gradually progressed to the use of mechanical equipment.

The scum removed by the operation of the scum removing device is collected in the collection cistern and then discharged to the outside, and the collection cistern is fixedly installed on the water in the sedimentation vat.

Here, in the case of the water collecting container, scum collecting can be easily collected only by maintaining a proper height difference from the water surface, so that it is most important to maintain the position corresponding to the water level.

However, in the case of the existing collection cans, there is a problem that the structure is fixed to one place, and accordingly, it can not cope with the water level properly.

That is, in the case of the sedimentation basin, the water level varies from time to time, such as when water comes in or out. When the water level is changed, the height difference between the water cistern and the water surface is severely generated, and the collected scum can not be collected easily. There is a problem that the scum processing efficiency is deteriorated.

Conventionally, the 'float switch structure of the water purifier of the water purifier' of Registration No. 0173107 and the water purifier float switch structure of the public water purifier of Utility Model No. 1999-009168 disclosed in the registration number 20-0392939 And the 'regenerator position control device for scum removing facility' of Registration No. 10-1010831, but the above problem is still not improved.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a scum collecting apparatus, And a scum collecting device capable of automatic leveling and scum collecting by using buoyancy due to discharge and inflow and outflow of water. .

The present invention relates to a scum collecting device comprising a semicircular or rectangular main body installed across a coagulant, a sedimentation tank or a water channel of a water purification plant so as to collect and collect scum and suspended matter floating on the water, And a slider for sliding the main body upward and downward.

Before describing the present invention, referring to FIG. 1 to FIG. 4,

A scum collecting apparatus comprising a semicircular main body which is installed across a coagulating paper or a settling paper of a water purification plant so as to collect and collect floating matters and scum floating on the water, The main body 100 is provided with a slider 210 slidingly connected to the slider 210 of the slider body 200. The main body 100 is slidably connected to the slider 210 of the slider body 200, A buoyancy tank 110 having an air inlet 120 for discharging air, an air outlet 130 and a water valve 140 for introducing and discharging water into the interior.

The air injection port 120 is formed with an indirect injection plate 121 for inducing a stable buoyancy change in the buoyancy tank by uniform construction injection in the tank.

The contact point 160 and the lower contact point 170 are configured to be capable of adjusting the contact height at a portion of the main body 100 that is in contact with the water surface of the scum collecting portion, and the fixed wall submergence contact point 300 is formed in the nearby wall .

A scum discharge port for discharging scum and a scum drainage line for discharging scum water are formed in the lower portion of the scum collecting portion of the main body 100.

Hereinafter, the scum collecting apparatus for automatically collecting scum will be described in more detail.

First, the scum collecting device is installed across a coagulating paper or a settling paper of a water purification plant, and collects and collects floating matters and scum floating on the water of the coagulating paper or sedimentation paper.

The scum collecting apparatus of the present invention is mainly composed of the main body 100 and the air compressing apparatus.

The main body 100 is connected to the slider 210 of the wall and slides up and down. The main body 100 is typically formed in a semicircular shape or a U-shape, and one end of the shape may be longer than the other side.

The main body 100 includes a buoyancy tank 110. The buoyancy tank 110 is provided with an air injection injection valve 120 for injecting compressed air into the buoyancy tank 110 An air discharge valve 130 for discharging the compressed air to the outside, and a water valve 140 for flowing water into and out of the buoyancy tank 110.

The air injection port 120 is formed with an indirect injection plate 121 for uniformly injecting air injected into the buoyancy tank 110.

The indirect injection plate 121 is connected to the air injection port 120 and is configured to be perpendicular to the direction of the air injection port 120 so as to inject a direction in which the air is injected.

Each of the air inlet 120 and the air outlet 130 includes a solenoid valve, which is automatically opened and closed by the height of the water surface.

The main body 100 is composed of a phase contact point 160 and a lower contact point 170 which are brought into contact with the water level.

The constant wetting contact 300 is formed on one side of the slider body 200 and contacts the phase contact 160 or the lower contact 170.

The lower contact point 170 is positioned below the end of the one side of the main body 100. The lower contact point 170 is located above the end of the main body 100,

The normal contact point 300 is fixed and the contact point 160 or the contact point 170 of the slider main body 200 contacts the normal contact point 300.

The normally wet contact 300 may be selectively formed on one side of the main body 100 or the water purification plant by the user, so that the position where the normal wetting contact 300 is formed is not limited.

However, the basic configuration is always below the water level, and when the water level becomes significantly lower, it may be adjusted to be positioned manually, semiautomatically or automatically below the water surface.

Although the phase contact 160, the lower contact 170 and the constant wetting contact 300 are typically made up of sensors, the part normally referred to as the submerged contact 300, not the sensor, It can be applied to any product that comes into contact with the lower contact point 170.

On one side of the main body 100, a scum discharge port for discharging scum and a scum drain port for discharging scum water are formed.

The scum outlet and the scum drain can be shared or individually constructed.

In the present invention, the main body 100 and the buoyancy tank 110 are separated from each other. However, as shown in FIG. 3, a hollow portion may be formed in the main body 100 so that the hollow portion may serve as the buoyancy tank 110 And discharge of water, and inflow and outflow of water.

The main body 100 and the buoyancy tank 110 may be formed individually or integrally. The buoyancy tank 110 may be formed at a lower portion of the main body 100 as shown in the drawings of the present invention But may be formed on one side or both sides of the main body 100, respectively.

In the case of the main body 100, the buoyancy tank 110 and the buoyancy tank 110 of the present invention, the submarine injects, drains, and flows in and out of the air for diving, Sliding downward is the key.

The slider body 200 is formed at both ends of the agglomerated paper or the sedimentation paper of the water purification plant and is connected to the main body 100 to constitute a slider 210 for sliding the main body 100.

The slider 210 is formed with an upper portion or a lower portion so as to form a latching portion of a maximum flow so that the main body 100 is not separated from the slider body 200 when the main body 100 is slid to the upper or lower side.

In the present invention, a combination of the slider body 200 and the slider 210 for sliding the main body 100 has been described. However, a combination of a chain and a sprocket or a combination of a spur gear and a circular gear can be applied. The present invention is not limited to the combination of the slider body 200 and the slider 210 since the present invention can be applied to a structure in which the main body 100 can be raised and lowered.

A buoyancy-adjusting manual valve 400 is formed in the main body 100 so that the buoyancy tank 110 can be manually adjusted by the user.

This is for adjusting the buoyancy of the buoyancy tank 110 after the scum collecting device is installed for the first time.

When the main body 100 explains the operation principle of the up and down operation on the water surface in detail

First, when the buoyancy regulating valve 400 installed on the buoyancy tank 110 is opened for the operation of the main body 100, the air escapes and the buoyancy tank 110 is filled with water so that the contact point 170 is immersed in the water, The settings for the adjustment are completed.

The principle of operation of the main body 100,

When the water level rises and both the phase contact 160, the lower contact 170 and the normally wet contact 300 are submerged in water, the air injection solenoid valve 120 is automatically opened and the air exhaust electromagnetic valve 130 is closed The compressed air is injected into the buoyancy tank 110 and the water is discharged through the water valve 140 so that the main body 100 rises due to an increase in the buoyancy of the buoyancy tank 110. [

The operation principle of the lowering operation of the main body 100,

When the water level of the water drops to lower the water level and the contact 160 is positioned on the water surface and only the lower contact 170 and the normally wet contact 300 are below the water surface, The air in the buoyancy tank 110 is discharged while water flows into the buoyancy tank 110 through the water valve 140. As a result, the buoyancy of the buoyancy tank 110 is increased, .

Hereinafter, the operation principle of the up and down operation will be briefly described briefly.

When the three contacts of the phase contact 160, the lower contact 170, and the constant wetting contact 300 are below the water surface, the main body 100 is raised,

When the phase contact 160 is exposed above the water surface by the rise of the main body 100, the main body 100 is lowered.

At this time, the lower contact point 170 and the normally wet contact point 300 are always located below the water surface.

According to the present invention as described above, the semicircular main body for collecting scum can be automatically raised and lowered according to the water level, and when the main body is lifted or lowered, the buoyancy tank In addition to injecting and discharging air, water can be flowed into and out of the buoyant tank, allowing the pump to automatically raise and lower the body, inject air into the buoyancy tank, discharge water, The collection of scum can be done automatically, and the labor cost can be reduced.
