Description

Wastewater Remnant Separation Equipment {SEPARATOR OF REMNANT IN WASTEWATER}

The present invention relates to an apparatus for separating residues of wastewater, which separates residues contained in wastewater such as sewage, sewage, manure, and leachate from waste liquid. The present invention relates to a wastewater separation apparatus for efficiently treating wastewater by separating and separating the wastewater stepwise according to the type.

In general, wastewater such as leachate, sewage, sewage, and manure of garbage generated at industrial sites or at home contains a large amount of residue, and when it is disposed of as landfill, soil is contaminated by wastewater and the natural environment is destroyed.

Accordingly, separate residues such as sand, contaminants, etc. in the wastewater are separated and then purified by a purification facility and discharged into rivers to reduce environmental pollution.

Conventionally, there is a treatment method in which food waste generated in various food companies, beverage companies, group meal centers, large restaurants, and the like is dried and used as compost after maintaining proper temperature and humidity. There is a disadvantage in that a drying device is required, and the cost of drying food waste is high.

In addition, manure from toilets and manure generated from various barns are treated as drugs and recycled as compost. However, this uses a large amount of chemicals, which contaminates the water quality of the river and has a high treatment cost.

Furthermore, conventionally, Patent Registration No. 10-214880 has developed a device for removing vinyl and contaminants in food waste, which collects various food wastes contained in plastic bags, puts them in the garbage input device, and quantifies the input food waste. A certain amount is fed directly downwards by a supply device, and the food waste and plastic bags supplied from the fixed-quantity supply device are cut in a predetermined length and shape by a plastic bag cutting device, and then the cut food waste and plastic bags are transferred to a conveyor. At the end of the vinyl removal device can be separated by removing only the cut plastic bag.

However, the conventional vinyl and dust removal apparatus contains a lot of moisture in the separated vinyl and the impurities, and thus separates the water and removes the waste material, thereby reducing the efficiency of treating waste materials, and removing small residues such as sand and seeds. The disadvantage is that it can not be processed.

Particularly, the apparatus for processing a fines, which is filed by the present inventors and registered in Korean Patent No. 10-156867, greatly improves the invention filed by the present inventors and registered in Korean Patent No. 20-47152, so that various residues can be efficiently separated from the waste liquid. The separator and the cyclone separator are combined, and the screen separator separates the contaminants of a predetermined size or more, and the cyclone separator separates the minerals such as sand which are not separated from the screen separator.

However, since the conventional wastewater treatment system may contain some residues suspended while passing through the screen separator in the wastewater introduced into the cyclone separator, the waste liquid passed through the cyclone separator may be processed again. There is a disadvantage that the efficiency is lowered.

Of course, the size of the residue that can be separated in the screen separator can be made as small as possible, but this has the disadvantage that the amount of waste water to be treated with the screen separator is reduced to increase the treatment time of the waste water.

The present invention was devised to solve the problems of the prior art as described above, and an object of the present invention is to dewater-separate the residues contained in the wastewater in stages according to the size and type thereof, and to treat wastewater such as sewage, sewage, manure and leachate. The present invention provides an apparatus for separating residues of wastewater which can efficiently separate residues contained therein.

In order to realize this, the present invention is a wastewater residue separation device for separating wastewater into residues and waste liquids, and a plurality of screen rotors spaced apart from each other at regular intervals are powered and inserted between the exit sides of the screen rotors, respectively. A first screen separator for separating the residue from the wastewater introduced from the outside by a plurality of remaining residue separating plate is power rotated, a first storage tank for storing the wastewater passing through the first screen separator, wastewater in the first storage tank Pump for power transfer, the lower portion is formed in a conical reverse phase is connected to the outlet side of the pump is rotated waste water by the pumping force of the pump to separate the residue of the waste water according to specific gravity, the same as the first screen separator It is formed in the shape of the residue from the wastewater flowing out of the upper portion of the cyclone separator A second screen separator for separating the residue having a smaller particle size than the residue separated from the first screen separator, and a second storage tank for discharging the waste liquid passing through the second screen separator to the outside and rotating with power A screw screw dehydrator for discharging the waste liquid to the outside, while transferring the remaining liquid submerged in the lower portion of the cyclone separator by forming a waste liquid discharge member for discharging the waste liquid at the center, and having a screw to be rotated by power.

That is, the residue separation device of the wastewater according to the present invention includes a first screen separator 1 for firstly separating the residue from the wastewater, a first storage tank 2 for storing the wastewater passing through the first screen separator 1, A pump 3 for power transfer of the wastewater in the first storage tank 2, a cyclone separator 4 for separating residues such as sand from the wastewater transferred by the pump 3, the cyclone separator 4 In the second screen separator (5) for separating the residue from the waste water separated from the residue, such as sand in the second, the second storage tank (6) containing the waste liquid passed through the second screen separator (5) to discharge to the outside ), A screw-screw dehydrator 7 for dewatering and transporting the remaining residues to the lower portion of the cyclone separator 4, a screw-screw feeder 8 for power-feeding the residues flowing out of the screw-screw dehydrator 7, and the agent 1,2 screen separation It consists of a screw press (9) for compressing and discharging the residues flowing out from the machine (1, 5) and the screw screw feeder (8).

Here, the first screen separator 1 includes a plurality of screen rotors 1a spaced apart from each other, and a residual separator 1b is rotated by the motor 1c, and a plurality of screen rotors 1a exit between the plurality of screen rotors 1a. Residual separation plate (1b) of each is inserted, and the residue is separated from the wastewater introduced from the outside primarily.

After connecting the first storage tank (2) and the cyclone separator (4) by a pipe (11), a pump (3) is installed on the pipe (11) to pass through the first screen separator (1) The waste water stored in the first storage tank 2 is transferred to power.

The cyclone separator (4) is formed in the reverse conical phase is connected to the outlet side of the pump (3), by rotating the waste water by the pumping force of the pump 3 to separate the residue of the waste water according to specific gravity, The waste water is ejected along the inner circumferential surface by the pump 3 to rotate inside.

The second screen separator 5 is formed in the same shape as the first screen separator 1, and the plurality of screen rotors 5a and the residual separator 5b spaced apart from each other are driven by the motor 5c. In addition to the rotation, a plurality of residue separation plates 5b are respectively inserted between the outlet sides of the plurality of screen rotors 5a, and the residues are separated secondarily from wastewater flowing out of the upper portion of the cyclone separator 4, in particular. Residuals having a smaller particle size than the residues separated from the first screen separator 1 are separated, and the waste liquid passing through the second screen separator 5 is discharged to the outside via the second storage tank 6. do.

The screw screw dehydrator (7) has a screw (7a) that is rotated by the power of the motor (7c) and the waste liquid discharge member (7b) for discharging the waste liquid in the center is connected to the cyclone separator (5) The waste liquid is discharged to the outside while power is transferred to the lowered part of the lower portion, and the screw screw feeder 8 connected to the outlet of the screw screw dehydrator 7 rotates the screw 8a which is rotated by the power of the motor 8b. It retains and power transfers the residue which flows out from the said screw dehydrator (7).

And the screw screw dehydrator 7 used in the present invention, as shown in Figure 5, a screw (7a) is rotated by a motor (7c) is built in the screw body (7d), the screw body (7d) An inlet formed at the lower end of the cyclone separator 4 communicates with the lower end of the cyclone separator 4, and an outlet of the upper end communicates with the inlet side of the screw screw feeder 8, and discharges the waste liquid below the outlet of the screw body 7d. The member 7b is connected.

In particular, the waste liquid discharge member 7b forms a plurality of liquid discharge holes 7g at the lower end of the case portion 7f that is coupled to the screw body 7d, and surrounds the liquid discharge hole 7g as a whole. The liquid induction part 7h induces and discharges the waste liquid passing through the liquid discharge hole 7g to the outside.

The screw press 9 has a screw 9a which is rotated by the power of the motor 9b so that the residues flowing out from the first screen separator 1, the second screen separator 5 and the yarn screw feeder 8 remain. After compressing, the waste liquid remaining in the residue is finally squeezed out and the residue is discharged to the outside.

For example, in the present embodiment, when the distance between the screen rotor 1a and the screen rotor 1a of the first screen separator 1 is 5 mm, the thickness of the screen rotor 1 a is 5 mm or less and two screens are formed. The distance between the rotors 1a becomes the thickness of the residue separation plate 1b, thereby allowing separation of residues having a particle diameter of 5 mm or more, and passing the residues smaller than 5 mm in diameter to the first storage tank 2. Stored.

In the present embodiment, when the distance between the screen rotor 5a and the screen rotor 5a of the second screen separator 5 is 3 mm, the thickness of the screen rotor 5a is 3 mm or less and two screens are formed. The interval between the rotors 5a becomes the thickness of the residue separation plate 5b, thereby allowing the separation of floating residues having a particle diameter of 3 mm or more, and finally, the waste liquid from which the floating residues are separated, into a second storage tank ( It is discharged to outside via 6).

Residual separation apparatus for waste water according to the present invention made as described above will be described with reference to FIGS.

When wastewater containing residues such as contaminants, sand, seeds and scum is introduced into the first screen separator 1, residues having a particle diameter of 5 mm or more are positioned on the circumference of the screen rotor 1a of the first screen separator 1. And separated by the residue separation plate 1b of the first screen separator 1, flowed into the screw press 9, and compressed and discharged, and the rest of the waste water flows into the first storage tank 2.

Wastewater introduced into the first storage tank (2) is introduced into the cyclone separator (4) along the pipe (11) by the pump (3) so that the residues, such as sand, sinks to the bottom, and the second screen separator ( 5) is put into.

Since the residues in the wastewater introduced into the second screen separator 5 are seeds, etc., which are suspended, most of the residues are located on the circumference of the screen rotor 5a of the second screen separator 5, and the second screen separator. (5) is separated by the residue separation plate (5b) is compressed and discharged by the screw press (9), the waste water passing through the second screen separator (5), that is, the waste liquid via the second storage tank (6) It is discharged to the outside.

Of course, the second storage tank 6 is for collecting wastewater, that is, waste liquid, which has passed through the second screen separator 5 and discharged to the outside, and discharges the waste liquid to the outside from the lower portion of the second screen separator 5. It is obvious that the second storage tank 6 can be deleted if possible.

Meanwhile, the residue that has sunk in the lower portion of the cyclone separator 4 is transferred by the screw screw dehydrator 7 and compressed at the outlet side so that the water in the residue is discharged from the liquid formed in the case portion 7f of the waste liquid discharge member 7b. It is easily discharged to the outside through the hole 7g and guided by the liquid guide portion 7h.

Then, the residue from which the waste liquid is dehydrated by the screw screw dehydrator 7 is discharged to the outlet of the screw screw dehydrator 7 and flows into the screw screw feeder 8, and the screw press 9 by the screw screw feeder 8. As a result, the residue is compressed by a screw press and the waste liquid is decompressed again to be discharged to the outside.

Thus, the residue separation device of the wastewater according to the present invention is easily separated in stages according to the size and buoyancy of the residue contained in the wastewater.

As described above, the residue separation device of the wastewater according to the present invention is separated from the residue contained in the wastewater by the first screw separator and the second screw separator according to the size and type, so that the seed of a small size floating Even there is an advantage that it can be easily separated.

In addition, small particles such as sand and fine contaminants having high specific gravity can be easily separated by a cyclone separator, and the water content of residues finally discharged to the outside by being dehydrated again by a screw screw dehydrator is further reduced. There is an advantage that it is easier to deal with the discharged residues.
