Description

Contaminant dehydration pressure feeding device

The present invention relates to a contaminant dehydration and pressure-feeding device, and more specifically, to a contaminant dehydration and pressure-feeding device capable of effectively conveying and dehydrating moisture contained in contaminants by linear reciprocating motion of a compression piston.

In general, a screen is installed in a sewage treatment plant to collect contaminants floating along with the water stream with a screen and then discharge the collected contaminants to the outside, and the sedimented contaminants are discharged to the outside using a sediment salvage device.

In this way, contaminants discharged through the screen and sediment lifting device have a high water content and thus have a large volume as well as a very large weight. If this is low, dehydration is not performed properly.

Accordingly, in the previously disclosed Patent Publication No. 10-2016-0127311, it is positioned between the dewatering part and the guide pipe, and a pressurized pipe through which it is connected in communication with the dewatering network is formed therein, and the pressurized pipe extends forward. As it becomes more sharp, the length of the pressure pipe is changed so that when the length of the pressure pipe is long, the diameter of the front end of the pressure pipe is formed to be small, and when the length of the pressure pipe is formed short, the front of the pressure pipe Variable pressing means for forming a large diameter of the end; as further comprising a variable pressing means having a pressure pipe communicating with the dewatering network is formed therein at the end of the dewatering unit, and the main variable ring of the variable pressing means By adjusting the number of attachment variable rings attached to and installed according to the size of the contaminants and installing them, the diameter of the front end of the pressurizing pipe is changed to appropriately control the degree of pressurization of the contaminants to the pressurizing pipe in the process of passing the pressurizing pipe. The technology has been previously presented.

However, in the prior art, contaminants of various sizes are effectively dehydrated under pressure, but due to the characteristics of the contaminant dewatering method using a transfer screw, the contaminant transfer speed is slow, and contaminants are caught between the pitches of the transfer screws, resulting in poor transfer, in particular, contaminants Since the conveying pressure is low, long-distance pressure conveying is impossible, so a conveying means including a separate conveyor must be provided to discharge the dewatered sludge.

In addition, in Patent Registration No. 10-1935428 developed to solve the problems of the prior art, a hopper part to which impurities are supplied, a hollow body part into which impurities from the hopper part are introduced, and the inside of the body are provided to transport and pressurize impurities It is composed of a transfer unit, a screen unit communicating with the body to dehydrate moisture, and a contaminant discharge unit installed in communication with the screen unit so that the dehydrated contaminants are transported and discharged to the outside. Although the technology has been registered in advance to allow moisture to be discharged to the screen and to easily discharge contaminants to the contaminant discharge unit by being pressurized while being conveyed by the conveying unit without jamming from the inside, however, due to the structural nature of the contaminants being compressed and dehydrated by back pressure in the compression taper section. , in the case of fine contaminants, it is difficult to expect a compression dehydration effect using back pressure, and thus, there is a problem in that a compression taper suitable for the contaminants must be replaced and applied according to the properties of the contaminants.

1 is a front cross-sectional view showing a preferred embodiment of the contaminant dewatering and pressure-feeding device provided by the present invention, and FIG. 2 is a cross-sectional view showing an enlarged main part of the contaminant dewatering and pressure-feeding device according to an embodiment of the present invention.

The present invention relates to a contaminant dewatering and pressure-feeding device, which is structurally improved so that the contaminant dewatering process and the pressure-feeding process are complexly performed by the linear reciprocating motion of the compression piston, so that the dewatering efficiency is improved and the structure is improved so that contaminants can be transported to a long distance As shown in the figure, it is largely composed of a compression chamber 100 , a compression piston 200 , a dewatering pipe body 300 , and a main configuration including a dewatering pressure adjusting unit 400 .

First, the compression chamber 100 according to the present invention is a cylindrical space for accommodating contaminants inside the piston pump.

The compression chamber 100 is formed in a cylindrical shape disposed in the transverse direction, and an inlet 110 communicating with a hopper for accommodating and storing contaminants is formed on the upper side.

And a compression piston 200 to be described later is installed on the rear side of the compression chamber 100 , and a discharge port 120 for delivering contaminants compressed by the compression piston 200 to the dewatering tube body 300 is formed in the front.

On the other hand, the inlet 110 of the compression chamber 100 is opened and closed by the knife gate 130 driven by an external power, and the knife gate 130 and the compression piston 200 are provided to be operated in conjunction with the control unit. do.

In the knife gate 130, linear motion is guided by the guide rail and a cutter blade is formed at the tip so that even if solids including tree branches are caught, they can be cut and removed, so that the inlet 110 is tightly closed.

3 is a configuration diagram showing the operating state of the contaminant dewatering and pumping device of the present invention, wherein the control unit (not shown) operates the compression piston 200 after the inlet 110 is closed by the knife gate 130 for compression It is provided to compress contaminants in the seal 100 .

Accordingly, the reverse flow of contaminants accommodated in the compression chamber 100 is prevented through the inlet 110 during the compression process, and thus, the power of the compression piston 200 is transmitted to the outlet 120 without loss, and the compression chamber 100 ) internal pressure loss is prevented.

The compression piston 200 according to the present invention is installed in a straight line with the outlet 120 of the compression chamber 100, and is linearly moved by the driving source 210 to discharge contaminants accommodated in the compression chamber 100 through the outlet 120. It is provided for compression transfer to the side.

The compression piston 200 is formed in the same shape as the inner circumferential surface of the compression chamber 100, that is, circular, and is provided to compress and transport contaminants while linearly reciprocating by a driving source 210 including oil and pneumatic cylinders.

At this time, the piston tube 220 formed of a hollow cylindrical tube body is fixedly installed in the compression piston 200 and moves along the inner circumferential surface of the compression chamber 100 to open and close the inlet 110 .

The piston tube 220 is installed on the outer surface or the rear end of the compression piston 200, and is linearly reciprocated on the expansion tube 230 communicating with the compression chamber 100, and the compression piston 200 is moved to the compression chamber ( 100) When moving inward, the inlet 110 is closed by the piston tube 220 to prevent contaminants from flowing into the back side of the compression piston 200 .

And, between the expansion tube 230 and the piston tube 220 is provided with an oil room 240 in which oil is isolated and accommodated by the airtight member 242 . The oil room 240 is replenished with oil through an oil hole formed on the outer circumferential surface of the expansion tube 230 .

As such, the oil stored in the oil room 240 performs a lubricating action between the inner circumferential surface of the expansion tube 230 and the outer circumferential surface of the piston tube 220, and friction noise and Abrasion is significantly reduced.

The dewatering pipe body 300 according to the present invention is connected to the outlet 120 of the compression chamber 100, and a plurality of perforations 310 are formed on the outer surface so that moisture contained in contaminants is dehydrated.

2 to 3 , the dewatering pipe body 300 is detachably installed at the end of the compression chamber 100 by a flange, and contaminants transferred by compression through the outlet 120 of the compression chamber 100 are dehydrated. The dehydration treatment is carried out in the pipe body 300 area. At this time, the dehydrated moisture is discharged through the plurality of perforations 310 and collected in the drain pipe 321, and the dewatered contaminants are intermittently riding on the pressure pipe body 410 to be described later. It is conveyed and processed by pressure to a predetermined discharge position.

On the other hand, as the contaminants subjected to compression and dewatering in the dewatering tube body 300 are transported by the linear reciprocating force of the compression piston 200, that is, intermittently conveyed by pressure, even if contaminants are caught in the perforation 310, the compression piston The clogging phenomenon of the perforation 310 is significantly reduced because it is easily separated by being impacted and adhered by the contaminants conveyed by the 200 .

In addition, the dewatering tube body 300 may be washed by the washing means 320 .

The washing means 320 is installed to surround the dehydration pipe body 300, a chamber 322 having a drain pipe 321 formed therein, and a chamber 322 installed in the chamber 322 to wash water on the outer circumferential surface of the dehydration pipe body 300 Includes a nozzle 323 for spraying.

In this case, the washing water supplied to the nozzle 323 may be recycled by using water supplied through a water supply, or by collecting and filtering moisture discharged from the dehydration pipe 300 .

The outer peripheral surface of the dewatering pipe body 300 is washed by the washing water sprayed through the nozzle 323 of the washing means 320, and contaminants caught in the perforations 310 are quickly removed, thereby dehydration efficiency according to long-term continuous operation. deterioration is prevented.

4 is a block diagram showing the operating state of the dewatering pressure adjusting unit of the contaminant dewatering and pressurizing device. The dewatering pressure adjusting unit 400 according to the present invention is connected to the dewatering pipe body 300 to guide the movement of the dewatered contaminants. A gate disk 420 is provided so as to induce a bottleneck according to movement of contaminants by adjusting the opening cross-sectional area of the pipe body 410 and the pressure feeding pipe body 410 .

That is, the open cross-sectional area of the pressure conveying tube body 410 is adjusted according to the moving distance of the gate disk 420. As an example, as the gate disk 420 is disposed downward as shown in FIGS. 4 (a) to 4 (b), the pressure conveying tube body (410) As the open cross-sectional area is reduced, the dewatering pressure due to the bottleneck increases.

The gate disk 420 has an inclined surface 421 that decreases in thickness toward a lower end thereof, and the inclined surface 421 may be formed as a rounded surface or a flat surface.

As a result, the contaminants passing through the dewatering pipe body 300 are moved in an inclined motion along the inclined surface 421 and are guided to be transferred to the pressure-feeding pipe body 410 open area. It minimizes the conveyance defect that foreign matter is caught on the disk 420 .

In FIG. 4 , the dewatering pressure control unit 400 is formed to communicate with the pressure feeding pipe body 410 , and has a guide compartment 430 , which guides the movement of the gate disk 420 , and one end is connected to the gate disk 420 . and a rod rod 450 for controlling the movement distance of the gate disk 420 by the pitch movement of the control member 440 .

According to this, as the gate disk 420 is positioned in proportion to the pitch movement distance according to the forward and reverse rotation of the control member 440, the pressure pipe body 410 open cross-sectional area is simply adjusted, and the contaminant properties change in the field. It has the advantage of being able to precisely set the dewatering pressure attached to it by responding immediately to it.

For example, in the case of a contaminant having a relatively high moisture content, the compression rate can be increased by moving the gate disk 420 downward through the control member 440. It is desirable to raise 420 upwards.

5 is a configuration diagram showing another embodiment of a dewatering pressure adjusting unit in the foreign matter dewatering pressure feeding device according to the present invention, and a dewatering tube body ( 300) may be provided so that the position is automatically adjusted in connection with the dehydration pressure acting within.

That is, the control member 440 and the rod rod 450 are separated, and an elastic body 460 is installed therebetween, so that the gate disk 420 is elastic in the inner direction of the pressure pipe body 410 by the elastic body 460 . It is provided so that the conveying force acts.

The control member 440 is screw-coupled from the upper side of the dehydration pressure control unit 400 , so that the control member 440 is moved up and down in pitch according to the rotational direction to adjust the compressive strength of the elastic body 460 .

When the contaminants pumped through the piston reach the gate disk 420 , the dewatering pressure is applied in the dewatering tube 300 by the cross-sectional area of the pressure-feeding tube body 410 narrowed by the gate disk 420 .

At this time, as the dewatering pressure increases, the elastic body 460 is compressed in proportion to it, so that the gate disk 420 is moved upward in the guide compartment 430 so that the open cross-sectional area of the pressurized pipe body 410 is changed more widely.

As such, when the dewatering pressure acting in the dewatering tube body 300 increases, the gate disk 420 moves while compressing the elastic body 460 to expand the open cross-sectional area of the pressure-feeding tube body 410, and vice versa, the dewatering pressure in the dewatering tube 300 When this is lowered, the gate disk 420 is moved by the elastic force of the elastic body 460 and the dewatering pressure is automatically adjusted in such a way that the open cross-sectional area of the pressure feeding pipe body 410 is reduced, preventing mechanical overload and the pressure feeding pipe body 410 It can reduce the pressure loss inside.

Furthermore, by adjusting the compressive strength of the elastic body 460 through the adjusting member 440, the contaminants can be effectively dehydrated in response to the properties and moisture content of the contaminants being compressed, so that the contaminants of various properties can be complexly processed. this is provided
