The present invention relates to a sediment sorting processor and a method of treating the sewage mixed with water generated by the use of industrial water at an industrial site (for example, underground excavation, construction, etc.) to reuse the water. It is about.

The conventional method of treating water mixed with earth and sand in an industrial site is to store water containing mixed earth and sand in a large tank and to drain relatively clean water by using soil that is heavier than water sinking to the bottom of the tank as time passes. You are sending or reusing it.

However, this treatment method takes a lot of time for the sorting process of the water because the soil is mixed with the water is pumped to the tank sinks to the bottom of the tank through a lot of time, and also because the size of the tank is large I have a problem.

The present invention has been made to solve the problems of the prior art as described above, the object of which is to filter out the soil three times through the earth segregation system to effectively produce the water, and also to quickly produce water In addition, the present invention provides a sediment sorting processor and a method of treating the same, which can increase the reproduction of water even though the size of the facility is relatively reduced compared to the related art.

In order to achieve the above object, the present invention provides a feed box for introducing water mixed with earth and sand into the earth and sand sorting processor, and a primary screen for separating the water and water into the feed box by vibrating means. And, the collection tank for collecting the water containing the earth and sand from the primary screen, the cyclone for separating the soil and water is connected to the water in the collection tank via the suction lake by the pumping means, and through the cyclone It characterized in that it comprises a secondary screen for separating the soil by the vibration means secondary.

In addition, the method of treating the water mixed with the earth and sand, the water is sent to the primary screen vibrating by the vibrating means through the feed box to discharge the soil more than 5mm from the primary screen, water containing less than 5mm of soil Collecting the primary to a collection tank; In this step, the water collected in the collection tank is transferred to the cyclone connected to the suction hose by the pumping means to centrifugally separate the water and the soil, and the separated water is primarily sent to the overflow tank, and the remaining soil is vibrated by the vibration means. Delivering to the secondary screen to the; Discharging more than 0.3 mm of the earth and sand delivered to the secondary screen in the above step, and collecting the water including the remaining 0.3 mm or less of soil to the collection tank again; And separating the water from the cyclone through the pumping means again with the water collected in the collection tank in the step and sending the separated water to the overflow tank secondarily.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the middle frame 14 supported by the base frame 12 is fed with a feed box 10 for introducing water mixed with soil to the primary screen 30 to be described later. A plurality of springs installed on one side of the uppermost side through the bracket 16 installed on both sides of the middle frame 14 to induce vertical vibration of the first and second screens 30 and 32 to be described later ( 18, a bracket 20 for supporting the upper portion of the spring 18 is connected to both screen frames 24 through the pin 22, the support frame 26 on the upper portion of the frame 24 A plurality of vibration motors 28 which are fixed and provide vibrations are installed. The screen frame 24 is provided with a primary screen 30 and a secondary screen 32 for filtering and moving the soil contained in the water.

In addition, a collection tank 34 is installed between the middle frame 14 and the base frame 12 to collect water passing through the first and second screens 30 and 32 and the collection tank. A pumping means 38, such as a rubber sand pump motor, is connected and installed through the base frame 12 to the pipe 36 connected to one side of the 34, and connected through the pumping means 38. The suction hose 40 is connected to the cyclone 42 so that the water in the collection tank 34 by the pumping means 38 is supplied to the cyclone 42 to centrifuge the water containing the earth and sand, the cyclone An induction pipe 44 for discharging the separated earth and sand to the secondary screen 32 is formed at the lower part of the 42, and a discharge pipe 48 for discharging the separated water to the overflow tank 46 is formed thereon. .

In the above, the mesh of the primary screen 30 is 5mm × 70mm, and only the soil having a size of less than 5mm of soil contained in the water is sent to the collection tank 34 with water, and the soil of 5mm or more is configured to be discharged outward. , The mesh of the secondary screen 32 is 0.3mm × 70mm to send only the soil of less than 0.3mm in size of the soil contained in the water to the collection tank 34 with the water, and more than 0.3mm of soil is discharged out It is.

In addition, in the case of the primary screen 30, as shown in FIG. 3, the soil is inclined toward the discharge side, while in the case of the secondary screen 32, the soil is inclined in the opposite direction from which the soil is discharged. The reason for this is that in the case of the primary screen 30, the relatively thick soil (5 mm or less) is filtered, so that the separate discharge of the soil is smooth, so that a smooth slope is provided in the discharge direction of the soil. In this case, relatively light and soft fine soil (0.3mm or less) is filtered out, so that the soil is discharged out before the sieve is filtered. Therefore, the soil is inclined in the opposite direction to the discharge direction to give the soil an identity. By weaving more soil, it is to facilitate the separate discharge of soil.

In addition, in the case of the secondary screen 32, the first and second stage screens 32a and 32b are separated and configured, so that the inflow of soil is made through the first stage screen 32a, so that the first stage screen 32a is two. However, compared with the screen 32b, the service life becomes short. Therefore, by separating and installing the secondary screen 32 as the first and second stage screens 32a and 32b, the secondary screen 32 can be replaced separately and economically, while the inclination of the secondary screen 32 is reduced. It has the advantage of compacting the space secured.

On the other hand, the inside of the collection tank 34 is installed through the guide plate 52 installed in the collection tank 34 in order to prevent the water filled in the collection tank 34 overflows, the collection tank In the 34, the inclined plate 54 is installed to have an inclination in the direction in which the primary and secondary screens 30 and 32 are installed, and the collection tank 34 through the primary and secondary screens 30 and 32. Water to be collected is primarily to be collected through the inclined plate 54 to cause the soil contained in the water to quickly sink to the bottom of the collection tank 34. In addition, a drain port 56 for cleaning the collection tank 34 is installed at a lower portion of the collection tank 34.

In the figure, reference numeral 58 is a discharge pipe connected to the overflow tank 46 and sent to the water storage tank 60 (see FIG. 5), and 62 is installed at the upper side of the collection tank 34 to collect the tank. (34) is an overflow pipe which is sent to the water storage tank 60 when the water overflows, and 64 shows the earth and sand receiver for guiding the discharge of the soil.

In the present invention configured as described above, as shown in FIG. 5, when the water containing the earth and sand flows through the feed box 10, the water passes through the primary screen 30 to vibrate, and the soil and water are primarily. Is separated. That is, more than 5mm of soil is discharged out, and the water is collected into the collection tank 34 together with the remaining 5mm of soil.

The water containing the soil collected in the collection tank 34 as described above is sent to the cyclone 42 connected to the suction hose 40 by the pumping means 38 connected to the pipe 36 to centrifuge the cyclone 42. The sediment and water are separated by primary separation and the separated water flows into the overflow tank 46 through the discharge pipe 48, and the remaining wet soil is vibrated along the induction pipe 44. It is sent to (32) to separate the soil and water. At this time, more than 0.3mm of the soil is discharged out, the water containing the soil less than 0.3mm is collected by the collection tank 34 again.

As described above, the water flowing through the feed box 10 is separated from the earth and sand in the primary screen 30 and collected through a collection tank 34, and the centrifugal separation of the earth and water from the cyclone 42 and the secondary screen 32. As the process of separating the soil and water is carried out, the water passed through the secondary screen 32 is finally centrifuged in the cyclone 42 and flows into the overflow tank 46 along the discharge pipe 48 and then discharged. Filled in the water storage tank 60 through the pipe 58 is to be converted into reusable water.

As described above, the present invention is to provide a more effective technology for reproducing water compared to the prior art by filtering the earth and sand three times through the earth and sand separator.
