Description

Filtering device for sewage and waste water using winch}

The present invention relates to a wastewater treatment water filtration device using a winch, and more particularly, to wastewater treatment using a winch to remove suspended solids, dissolved substances and bacteria contained in the treated water in a wastewater treatment facility. It relates to a water filtration device.

Generally, sewage treatment water treated in sewage treatment facilities contains suspended solids and dissolved solids, so when you want to use the sewage treatment water as water, sewage treatment that filters the suspended substances and dissolved substances is filtered. Further water filtration is required.

The conventional wastewater treatment water filtration device is very complicated in structure and occupies a lot of installation space by continuously arranging a plurality of filtration devices that filter only suspended or dissolved substances. As the necessary backwash tank and backwash pump are separately required, there is a problem that the structure becomes more complicated and maintenance is not easy.

In order to solve this problem, the complex water treatment filtration device with improved sterilization and backwashing function (Registration No .: 10-1335668) effectively filters the dissolved and suspended substances contained in the sewage water through separate backwashing in the inner and outer cylinders. In addition to this, a device that can remove bacteria contained in sewage treatment water has been suggested.

However, in order to sufficiently compress the first filtration member, the length of the pressurized cylinder should be long. Since the pressurized cylinder has a structure exposed to the upper part of the outer cylinder, the longer the pressurized cylinder, the higher the height of the device becomes, which wastes space. However, the height was too high, there was a difficult problem in the actual installation.

In order to reduce the waste of space for the reasons described above, 'Sewage Wastewater Treatment Water Filtration Device using Sponge Media (Registration No .: 10-1488965)' suggests a structure in which the pressure cylinder of the pressurizing means is mounted inside the outer cylinder to reduce the height of the device. The streamlined backwashing system from the outer casing to the inner casing was simplified.

However, even if the pressure cylinder is installed inside the outer cylinder, the space occupied by the pressure cylinder in the outer cylinder is so large that it is difficult to secure enough space for the dissolved material of the treated water flowing into and discharged from the lower part to be filtered. Since there is a problem that the inefficient aspect is highlighted, it is a time when a new technology development research that can improve this is urgently required.

In addition, the rising barrier 140 also serves to prevent the first filtration member 120 from leaking to the outside.

That is, the lifting prevention jaw 140 is formed to protrude in an inner direction along the inner wall surface of the inner chamber 100 so as to be connected to the lower end of the treated water inlet pipe 110 connected to the inner chamber 100 in an extension line, and thus the weight plate 510. ) Is prevented from rising to a position higher than the treated water inlet pipe 110 and the air discharge pipe 130. If the rise prevention jaw 140 is formed at a lower position than the treated water inlet pipe 110, a stepped space may be formed between the treated water inlet pipe 110 and the raised stoppage 140 to cause a water trap. Accordingly, the lift bar 140 prevents the weight plate 510 from being moved upward or higher than a predetermined position, and prevents the first filtration member 120 accommodated inside the inner chamber 100 from coming out. It works.

The outer chamber 200 of the present invention is configured to filter the dissolved substances contained in the treated water in the process of flowing through the inside of the inner chamber 100, the treated water filtered by the floating material flows into the lower portion and discharged to the upper one side.

It is the structure which backwashes the member 220.

That is, the backwashing means 400 receives the treated water temporarily stored in the state in which the floating material and the dissolved material are removed in the upper portion of the outer chamber 200 through the inflow pressure of the compressed air supplied from the outside in the direction opposite to the flow direction. It acts to backwash the first filtration member 120 and the second filtration member 220.

To this end, the backwashing means 400 includes a first backwash water transport box 410, a second backwash water transport box 420, a first compressed air supply pipe 430, a second compressed air supply pipe 440, and a first backwash water wash It comprises a discharge pipe 450 and the second backwash water discharge pipe 460, each of the features are as follows.

The first backwash storage box 410 guides the treated water flowing into the lower portion of the inner chamber 100 according to the injection of compressed air to be pumped to the upper portion of the inner chamber 100. The inner chamber 100 has a cylindrical shape. It is installed in communication with the lower portion of the upper and lower surfaces, respectively, a plurality of first pressure holes 411 are perforated symmetrically up and down.

The second backwash storage box 420 guides the treated water temporarily stored in the lower portion of the outer chamber 200 to be pumped to the upper portion of the outer chamber 200 according to the injection of compressed air. It is installed inside of the 200 and the plurality of second pressure holes 421 are drilled symmetrically up and down on the upper and lower surfaces, respectively.

The first compressed air supply pipe 430 is for supplying compressed air to the inside of the first backwash water box 410 so as to pressurize the treated water upwards to act as backwash water, and the first backwash water transport box 410. Branched at one side of the) is provided with an on-off valve 431 to control the compressed air.

The second compressed air supply pipe 440 pressurizes the treated water downward in the interior of the outer cylinder 200 so that the treated water of the outer cylinder 200 flows quickly into the first backwash container 410, the outer cylinder 200. It is provided on the upper side of the on-off valve 441 for regulating the compressed air is provided.

The first backwash water discharge pipe 450 discharges the treated water removed by backwashing the suspended solids attached to the first filtration member 120 while being pumped through the first backwash water transport box 410. It is installed on one side of the 110 and is configured to be interrupted by the on-off valve 451.

The second backwash water discharge pipe 460 is pumped through the second backwash water transport box 420 to discharge the treated water removed by backwashing the dissolved substances attached to the second filtration member 220 to the outside, It is installed on the upper side of the 200 and the end is connected to the first backwash water discharge pipe 450 and is configured to be interrupted by the on-off valve 461.

In summary, the treated water temporarily stored in the outer chamber 200 according to the pressure of the compressed air supplied into the first backwash container 410 may be provided at the lower portion of the inner chamber 100 or the lower portion of the outer chamber 200. The floating material or the second filtration member 220 attached to the first filtration member 120 by acting as a backwash water while being pumped upward through the first backwash water transport box 410 or the second backwash water transport box 420. Dissolved substances attached to them are backwashed and discharged to the outside.

In summary, the backwashing process may be described as branched compressed air flows into the first compressed air supply pipe 430 and the second compressed air supply pipe 440 through a blower, and the first filtration member 120 is first introduced. When the winch assembly 600 is relaxed by the operation of the winch assembly 600, the pressure of the inner chamber 100 is lowered, the compressed air is introduced into the first compressed air supply pipe 430, the inner chamber 100 is backwashed, the first filtration member 120 ) Is compressed by the self-weighting means 500, the pressure of the inner chamber 100 is increased and the pressure of the outer chamber 200 is relatively low, so that compressed air flows into the second compressed air supply pipe 440 and the outer chamber ( 200) is backwashed.

However, the treated water inlet pipe 110 may not be discharged to the treated water inlet pipe 110 when the treated water backwashed with suspended substances and dissolved substances is discharged through the first backwash water discharge pipe 450 and the second backwash water discharge pipe 460. At the end of the first backwash water discharge pipe 450 is bent upward to a position higher than the portion connected to the treatment water inlet pipe 110, it is preferable to be provided with a backflow prevention portion bent downward again. At this time, the inlet valve 111 for controlling the inflow of the treated water is installed in the treated water inlet pipe 110. When the inflow of the treated water is opened, the inlet valve 111 is opened and the opening / closing valve of the first backwash water discharge pipe 450 ( 451 is closed, and when the treated water is discharged back, the inlet valve 111 is closed and the on / off valve 451 of the first backwash water discharge pipe 450 is opened.

The self-weighting means 500 of the present invention is installed on the upper portion of the first filtration member 120 to press the first filtration member 120 downward by its own weight to the first filtration member 120 and the first filtration member. Filtration through and backwashing means 400 is configured to enable backwashing.

That is, the self-weight pressing means 500 is moved downward by the self-weight to compress the first filtration member 120 to make the pores of the first filtration member 120 fine, so that the filtration of the first filtration member 120 The filtration function for the suspended solids through the fine pores, and during the backwashing, the treated water acting as the backwashing water is pumped to the upper portion of the outer chamber 200 instead of the inner chamber 100 so that the second filtration member 220 may be used. It acts to enable the backwash on.

To this end, the self-weighting means 500 includes a rod 511, a weight plate 510, a through hole 530 and a corrugated pipe 540, each of which is as follows.

First, the rod 511 is formed in the shape of a bar (bar) is installed on the upper portion of the first filtration member 120 inside the inner chamber 100, it is to be moved downward with the weight plate 510 vertically.

Second, the weight plate 510 is installed in the lower portion of the rod 511 to press and compress the first filtration member 120 while descending by its own weight.

The weight plate 510 may be arranged in multiple stages through various methods, which can be confirmed through FIG. 2, which shows an exemplary view of the weight plate 510 according to the preferred embodiment of the present invention.

Referring to FIG. 2, 2- (a) exemplarily shows that a single weight plate 510 may be used, and FIG. 2- (b) may stack and use a plurality of weight plates 510. By way of example, since the weight plate 510 can be laminated in various ways, the weight of the weight plate 510 lowered to the first filtration member 120 is adjusted according to the amount of water to be treated. Can be.

In particular, the side sealing (sealing) of the weight plate 510, the brush 520 is mounted along the side circumference of the weight plate 510 so that the weight plate 510 vertically along the inner wall surface of the inner chamber 100 It is characterized by reducing the friction between the weight plate 510 side and the inner wall surface of the inner chamber 100 when moved.

Conventionally, O-rings are frequently used for sealing, but when O-rings of rubber material are applied, the pressing force has to be large due to the adhesion force, but it has been moved up and down. For this reason, the side chamber and the inner chamber of the weight plate 510 operated by its own weight for smooth compression of the first filtering member 120 while restraining the first filtering member 120 accommodated in the inner chamber 100 from being separated. Adhesion with the inner wall surface of the (100) should be weak, so that it can be solved through the brush (520).

For reference, pieces of the first filtration member 120 may be prevented from being separated out of the inner chamber 100 by adjusting the simulation strength, length, and spacing of the brush 520. For example, when the length of the hair constituting the brush 520 is more than 3mm, the hair length is too long, causing the hair to bend due to the backwash pressure. When the hair length is less than 1 mm, a piece of the first filtration member 120 is formed on the brush 520. Since sticking occurs, it is preferable to use a brush 520 having a hair having a length of 1 to 3 mm (preferably 1 mm).

Third, the through hole 530 is formed to penetrate perpendicular to the weight plate 510 to allow passage of the treated water when the first filtration member 120 is pressed by the weight plate 510.

Fourth, the corrugated pipe 540 is installed to surround the outside along the longitudinal direction of the rod 511, to facilitate the vertical vertical movement of the weight plate 510. That is, the corrugated pipe 540 is a corrugated pipe wrapping the rod 511. When the weight plate 510 is moved downward by its own weight, the corrugated pipe 540 relaxes, thereby making it easy to compress the first filtration member 120. When the weight plate 520 is moved upward by the winch assembly 600, the corrugated pipe 540 is compressed to assist the vertical lifting force of the weight plate 520.

The winch assembly 600 of the present invention upwardly the self-weight pressure means 500 by a wire winch 630 which winds and unwinds the wire 620 connected to the self-weight pressure means 500 pressurized by the first filtration member 120. It is a configuration to move to.

First of all, in order to compress or relax the media through the existing pressurized cylinder, sufficient space was necessary in consideration of the large size occupied by the expensive pressurized cylinder weighing 70 kg. In order to install the pressure cylinder, the space constraint was large, since it had a dysfunction requiring about 170 cm of space.

For this reason, in the present invention, the winch assembly 600 is intended to be presented, that is, the winch assembly 600 is moved downwardly by non-powered pressurization and the self-weighting means 500 for pressing the first filtration member 120 is wire 620. ), The wire winch 630 is wound and unwinded by the operation of the wire winch 630 can move the self-weight pressure means 500 upwards, thereby allowing height adjustment of the self-weight pressure means 500.

To this end, the winch assembly 600 is configured to include a connector 610, a wire 620 and a wire winch 630, the features of each configuration will be described in more detail below.

First, the connector 610 is to connect the upper end of the rod 511 of the self-weight pressing means 500 and one end of the wire 620, various connectors 610, such as a ring can be applied.

Second, the wire 620 is wound and unwinded to the wire winch 630, one end is connected to the weight plate 510 by the connector 610 and the other end is fixed to the wire winch 630.

That is, the wire 620 is connected to the rod 511 of the self-weight pressure means 500 to move the weight plate 510 of the self-weight pressure means 500 as the wire winch 630 is wound or unrolled. In some cases, it may be moved downward to a certain position.

Third, the wire winch 630 is installed in the passage space 250 inside the outer chamber 200 to adjust the height of the weight plate 510 by winding or releasing the wire 620. That is, the other end of the wire 620 is fixed to the wire winch 630 to raise the weight plate 510 moved downward by its own weight in order to pressurize the first filtration member 120 vertically or in some cases. According to the adjustment, the weight plate 510 may be lowered vertically downward.

For example, when the thickness of the first filtration member 120 is 160cm and the thickness of the weight plate 510 is 2.6cm, the weight plate 510 is moved downward by its own weight to increase the thickness of the first filtration member 120. It can be compressed up to about 30cm, and then by pulling the wire 620 connected to the weight plate 510 by the control of the wire winch 630 to move the weight plate 510 vertically upward, the first filtration member ( 120 may be described in a relaxed manner.

 In addition, the passage space 250 formed on the inner upper side of the outer chamber 200 is a passage connecting the upper outer side of the outer chamber 200 and the inner chamber 100, and the weight plate 510 is moved downward by its own weight. When the winch assembly 600 is moved up by the rod 511 and the wire 620 connecting the weight plate 510 is provided with a space to pass.

At this time, the passage space 250 is formed to be larger than the diameter of the upper step than the bottom, the reason that the diameter of the top is formed larger than the bottom is because the wire winch 630 is stably seated on the stepped portion bordering the lower and To do so.

Hereinafter, the operation of the wastewater treatment water filtration apparatus using the winch according to the preferred embodiment of the present invention will be described in detail.

First, when the pressure sensed by the pressure gauge 132 installed in the air discharge pipe 130 is less than the reference pressure, the filtration process is possible through the first filtration member 120 and the second filtration member 220.

In this state, the treated water inlet pipe 110, the treated water discharge pipe 210, and the air discharge pipe 130 are opened, and the first compressed air supply pipe 430, the second compressed air supply pipe 440, and the first backwash water discharge pipe 450, the second backwash water discharge pipe 460 and the residual water discharge pipe 230 are closed, and the self-weight pressure means 500 moves downward by its own weight to pressurize the first filtration member 120.

Then, the treated water is introduced into the upper portion of the inner chamber 100 through the treated water inlet pipe 110, and the introduced treated water flows downward while passing through the first filtration member 120 to remove the suspended solids and filter the suspended solids. The treated water flows into the inside of the outer chamber 200 through the lower portion of the inner chamber 100, and the flow of the treated water flows upwards while being dissolved by the second filtration member 220 and the ultraviolet lamp 300. In the state where the various bacteria are removed is discharged to the outside through the treated water discharge pipe 210 to be utilized as water.

However, after the treatment chamber is filled inside the inner chamber 100, the treatment tube is not discharged through the air discharge tube 130, but is filtered through the first filtration member 120 and the second filtration member 220. 130 is closed.

On the other hand, when a backwashing process is required after the elapse of a predetermined time setting or when the pressure sensed by the pressure gauge 132 installed in the air discharge pipe 130 is greater than or equal to the reference pressure, the first filtration member 120 and the second filtration member ( 220) a lot of suspended substances and dissolved substances attached to the backwash process is required.

In this state, when the backwashing process is performed on the first filtration member 120, the first compressed air supply pipe 430, the second compressed air supply pipe 440, and the first backwash water discharge pipe 450 are opened, and The two backwash water discharge pipes 460, the treated water discharge pipes 210, the air discharge pipes 130, and the residual water discharge pipes 230 are closed.

Then, the compressed air flows through the first compressed air supply pipe 430 and the second compressed air supply pipe 440 into the inside of the first backwash container 410 and the upper portion of the outer chamber 200, and thus the external chamber. The treated water temporarily stored at 200 is pressurized upward by the first backwash water transport box 410, and the treated water is backwashed by the first filtration member 120 at a strong pressure by compressed air. Together with the suspended solids detached from the filtration member 120 is discharged to the outside through the first backwash water discharge pipe (450).

At this time, when the backwashing process for the second filtration member 220 is in progress, the self-weighting means 500 pressurizes the first filtration member 120 by its own weight and the first compressed air supply pipe 430 and the second backwashing water. The discharge pipe 460 is opened and the treated water discharge pipe 210, the air discharge pipe 130 and the residual water discharge pipe 230 are closed.

Then, the compressed air is introduced into the first backwash water storage box 410 through the first compressed air supply pipe 430, and the treated water temporarily stored in the outer chamber 200 is transported by the second backwash water transport box 420. The pumped water is pumped upward, and the treated water is backwashed by the second filtration member 220 with a strong pressure by compressed air, and the second backwash water discharge pipe 460 together with the dissolved substance desorbed from the second filtration member 220. Pass through and discharged to the outside via the first backwash water discharge pipe (450).

Then, the residual water discharge pipe 230 is opened to completely discharge the treated water remaining inside the external chamber 200 to the outside without being discharged through the second backwash water discharge pipe 460 to the inside of the external chamber 200. Is emptied, thereby finishing.

Therefore, since the weight plate 510 of the self-weight pressing means 500 presses the first filtration member 120 while moving downward by its own weight, not only the non-powered pressurization without additional power is possible, but also the external chamber 200. Space efficiency can be achieved by increasing the inflow rate of treated water containing dissolved substances.
