Description

Precipitation apparatus of inclined plate type having oil-water separating function}

The present invention relates to a swash plate type sedimentation device that also functions as an oil-water separation, and more particularly, a pair of discharge screws in which a feed pressure control groove is formed at a predetermined interval in a spiral-type winding direction with respect to a screw wound on a shaft. By providing the applied discharge means, it is possible to maximize the sludge discharge efficiency by reducing the transfer pressure load caused by the discharge of sludge when the sludge is discharged through the discharge screw, which is the discharge means, and contains floating oil components such as oil at the top of the settling tank. By applying a removing means to remove floating matter, the oil-water separation function is implemented through the removal means, enabling treatment of wastewater containing oil, while the washing means is applied to provide a combination of washing means and The present invention relates to a swash plate type settling device with an oil-water separation function to facilitate cleaning and maintenance of the swash plate inside the settling tank through washing when washing is required.

In general, water treatment facilities such as a water purification plant or a sewage treatment plant install and operate a settling basin to settle solid substances by storing treated water for a certain period of time or flowing at a low flow rate during physical or biochemical treatment.

When the sedimentation process is operated by installing the sedimentation basin as described above, the load on the turbidity in the filter media in which the filtration process, which is a subsequent process, is performed is reduced.

That is, no matter how well the blending and flocculation is performed in the blending and flocculation step, which is the previous step, if overflow is performed without sedimentation, the filter paper adversely affects.

The sedimentation process is the most widely used technology among solid-liquid separation technologies for removing solid substances in water, and uses the principle of separating particles and floating substances having a greater specific gravity than water by sinking to the bottom by their own gravity.

In the conventional sedimentation process, in order to increase sedimentation efficiency, various structures have been installed in the sedimentation basin to shorten the sedimentation distance of solid substances, thereby reducing sedimentation time and increasing the effective sedimentation area, thereby developing and applying technologies to reduce the surface load rate.

For example, there is a swash plate settling device that increases the effective settling area by installing several swash plates in a settling basin in which a plate having the same width as the width of the settling basin is inclined to form a certain angle with the floor.

However, in the conventional swash plate sedimentation apparatus, there is a problem such as density flow in which the incoming raw water is not uniformly distributed to all swash plates, the problem of short circuit flow in which precipitation is not made through the entire swash plate and flow occurs only in the central part, and inflow source water and Depending on the flow direction of the solid material, the flow of the incoming raw water is obstructed or the solid material is re-suspended in a complex structure to solve the problem, and some have not obtained sufficient effects.

In addition, in the conventional swash plate sedimentation device, since the discharge screw, which is the discharge means, is provided by a single screw, the discharge of sludge is concentrated on the single discharge screw, reducing the sludge discharge efficiency and at the same time, the load due to the transfer of the discharge screw for discharging sludge is increased. Due to the large occurrence, there is a problem that the durability of the discharge means is deteriorated.

In addition, there is a problem in that the conventional swash plate sedimentation apparatus does not have a function of separating oil and water, so that oil-water separation is not performed during treatment of wastewater containing oil, which makes it difficult to separate oil-water from the wastewater.

Moreover, the conventional swash plate sedimentation apparatus has a problem that maintenance through washing is not easy because a separate washing means must be applied to wash the internal swash plate when washing is required.

Therefore, when discharging sludge through the discharging screw, which is a discharging means, it is possible to maximize the sludge discharging efficiency by reducing the transfer pressure load caused by discharging the sludge, and applying a separate oil-water separation function to prevent wastewater containing oil. A study on a swash plate type sedimentation device with a function of separating oil and water so that cleaning and maintenance of the sloping plate inside the settling tank can be easily performed by washing the swash plate when the swash plate is required to be washed with a washing means. And development is required.

Oil-water separation function, characterized in that it comprises a guide panel 230 for guiding the recovered floating material to the floating material discharge housing 150 side to discharge the floating material rolled by the scraper 220 to the outside of the settling tank 100 Inclined plate type sedimentation device that also functions The method of claim 1,
The swash plate 400 is installed inside the sedimentation tank 100, and is provided as a plurality of plates in which mountains and valleys are repeated in a horizontal direction. The method of claim 1,
The lifting wall 500 is installed on one side of the upper side where the discharge port 120 of the settling tank 100 is formed, and adjusts the discharge level of the treated wastewater through height adjustment, and the discharge port 120 of the settling tank 100 A first wall 510 fixedly installed on the inner floor on one side of the upper side where is formed,
A second wall 520 formed to move up and down in close contact with one side of the first wall 510,
An elevating shaft (not shown) that is connected to the second wall 520 and the lower end to adjust the elevation of the second wall 520 and
It is provided on the upper end of the lifting shaft (not shown), and a swash plate type sedimentation device having an oil-water separation function, characterized in that it comprises a lifting control handle (not shown) for adjusting the lifting and lowering of the lifting shaft through rotation. delete delete The method of claim 1,
The intensifying compressor 640 is made of synthetic rubber and has a cylindrical stator 641 having a helical compression chamber 641a penetrated therein, and a helical compression chamber of the cylindrical stator 641 having a helical protrusion 642a on an outer circumferential surface thereof. It includes a rotor 642 rotatably inserted into (641a), and a cylindrical sleeve 643 coupled to the outer peripheral surface of the cylindrical stator 641,
When the rotor 642 rotates, the compressed air of increased pressure is generated, so that the compressed air is increased inside the inlet 110, the injection hole 611 of the upper support bar 610, and the lower support bar 620 A swash plate type sedimentation device having an oil-water separation function, characterized in that spraying to the inside of the inlet 110 and the upper and lower sides of the swash plate 400 through the injection hole 621 of. The method of claim 1,
The wastewater is partitioned between the inlet 110 and the swash plate 400 through which the wastewater flows into the settling tank 100, and the c-shaped channels 171a are arranged in a zigzag shape in a row staggered to form a maze structure while , Inclined plate type sedimentation device with oil-water separation function, characterized in that it further comprises a flow distribution plate 170 for distributing the flow rate of wastewater flowing through the inlet 110 to spread over the entire portion of the swash plate 400. delete delete delete
