Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous automatic dewatering device for sludge generated in wastewater and sewage treatment, and particularly for pressure filtration, cake dewatering,
By automatically and continuously performing each process of cake removal and filter cloth cleaning, the moisture content of various sludges can be efficiently lowered, and the filter cloth can be maintained without clogging, and can also be manufactured for transportation. Concerning a possible continuous automatic pressurized dehydration device.

Currently, wastewater and sewage treatment is extremely urgent in terms of pollution prevention, but equipment costs are generally high, and small and medium-sized enterprises in particular cannot bear the burden.

For example, wastewater from washing of agitator vehicles for transportation at a ready-mixed concrete factory, wastewater from cleaning formwork, etc. at a factory for producing humid pipes, concrete piles, concrete members for prefabricated buildings, slate, etc., are generated daily compared to general factory wastewater. Although the amount is small compared to that of 2009, it contains fine sand and cement, which makes it highly alkaline, and it is impossible to directly discharge it into the public sewer system, so a settling tank is installed, which is extremely expensive. However, not only is there a risk of serious pollution such as flooding of surrounding areas or infiltration of groundwater during heavy rains, but it is also normal for sedimentation basins to become full sooner or later, requiring further expansion. Therefore, a filter breath or the like is installed to process the solids every day, and the generated solids are used as materials for secondary products such as blocks for fish reefs that do not require strength to the extent possible.
It is best to reuse filtered water as working water. However, filter breath etc. are usually batch processed, so the sludge remains in the filter for a long time.
During this time, the cement solidifies within the filter cloth and is difficult to remove even with subsequent cleaning, thus shortening the life of the filter cloth and increasing the initial equipment cost. It has the disadvantage that not only is it expensive, but the maintenance costs during use are also extremely high. For this reason, it is common practice to have wastewater treatment companies take over the wastewater, and in some cases, as a result of outsourcing to inferior wastewater treatment companies, wastewater is illegally dumped into public sewers, etc., which is extremely serious in terms of pollution prevention. There are many cases where unexpected accidents occur. This kind of case is almost the same in the case of mud-containing washing wastewater in the quarrying industry, and wastewater in the treatment of manure in the pig farming or poultry farming industry. The purpose of this application is to eliminate the drawbacks in the use of conventional filter braces, etc., and to improve
Continuous automatic pressurized dehydration that has sufficient filtration function to dewater sludge from the stone quarrying industry, pig farming, poultry farming, etc., has a relatively simple structure that prevents clogging of the filter cloth, and is highly maneuverable. The aim is to provide equipment at low cost, and as a result, by reducing the burden of equipment funding and maintenance costs for implementing pollution prevention equipment, it is possible to reduce the amount of sewage, wastewater, etc. necessary for pollution prevention. The aim is to make it possible to easily perform dehydration treatment and to promote its widespread use.

The continuous automatic pressure dewatering device of the present invention is installed between horizontal and mutually parallel drive rolls and support rolls located at substantially both ends of the device, and is pulled and driven from the support roll toward the drive roll, A belt-shaped endless filter cloth that circulates with the upper side as an outgoing process and the lower side as a returning process; a pressurized filtration and dehydration device positioned to sandwich the filter cloth vertically in the outgoing process following the support roll; A press roll for pressing a drive roll through the filter cloth to be driven by friction and transferring the cake after pressing and dewatering the cake on the filter cloth, and one or more press rolls pressed by the press roll. a receiving roll for dehydration; a cake peeling means comprising a scraper or the like for peeling off the cake, which makes the distance between the surface of the pressure roll and the cutting edge equal to or less than the thickness of the cake to be transferred; and a cake peeling means provided in the return step. The pressurized filtration and dehydration device consists of an upper shell and a lower shell, each of which corresponds to a hollow shell divided into upper and lower halves by one plane. The upper shell supports the filter cloth and is opposed to the lower shell, which is located in contact with the lower surface of the filter cloth, and has a required spacing between the upper shell and the lower shell, It has a lowering means consisting of a pneumatic cylinder or the like for being pressed toward the lower shell, and further has a partition for adjusting the pressure on the side surface on the exit side through which the filter cloth passes. There are some features.

The present invention will be explained below with reference to Examples and drawings.

All of the main parts of this device can be assembled into a set of mounts 1.

The endless filter cloth 3 is preferably made of felt made from natural fibers or synthetic fibers, and its width is not particularly specified, but it is usually about 2 TrL or less.

It is most preferable to select the thickness of the filter cloth 3 depending on the properties of the sludge, but it is usually about 4Tn! The thickness can be selected from within the range of n to 12 Wrm. For example, in the case of sludge from a ready-mixed concrete factory, etc., a thickness of about 6 WL is sufficient. It is preferable that the support roll 5 located at the starting end of the forward stroke is a floating roll, and that the shaft bearings 7 at both ends of the support roll 5 are moved by a tensioning device 9 made of, for example, a screw mechanism to tension the filter cloth 3 and act as a tension roll. .

The sludge S to be dewatered using this device is usually temporarily stored in a relatively small capacity mud storage layer (not shown), and then passes through a transport pipe 11 to a pressure pump 13 where it is applied to the required pressure. The sludge is pressurized and fed through the pipe 15 into the upper shell 19 of the pressurized filtration and dewatering device 17 through the sludge inlet 21.

Although any known pressure pump 13 can be used, it is preferable to use one that can be used in conjunction with the valve 14 and the like to adjust the pressure and flow rate according to the type of sludge S, solid content, etc.

Since the filter cloth 3 moves continuously, the thickness of the produced cake C is kept relatively thin, and therefore the filtration resistance is kept low, so for example, the pressure adjustment range is 0.2 kg/Cll to 1.0 K.
9/d1 Also, the flow rate adjustment range is 0.2R/Min-0.
Approximately 57T1/Mln is sufficient for applications such as a normal scale ready-mixed concrete factory. Pressure filtration and dehydration equipment 1
The upper shell 19 and lower shell 23 of No. 7 almost correspond to one hollow shell, for example, a hollow shell consisting of a rectangular hexahedron on a horizontal plane, that is, a box-shaped body, divided into upper and lower parts by a horizontal plane. death,
The filter cloth 3 is sandwiched in between to form a sealed body. The lower shell 23 is fixed almost horizontally to the pedestal 1, and has a drain port 2 on the bottom.
5 and piping 27, the filtered water can be sent to a raw water tank (not shown).

The upper surface of the lower shell 23 is located perpendicularly to the traveling direction of the filter cloth 3 and at an angle of about 20 degrees to about 60 degrees from the vertical plane in the opposite direction.
It has a plurality of support rods 29 that are inclined within a range of degrees, and supports the pressure applied to the filter cloth 3, and also functions as a drainer to facilitate the discharge of filtered water from the filter cloth 3. The upper shell 19 passes through the center of the upper surface part 31 and is on a vertical plane perpendicular to the traveling direction of the filter cloth 3, and usually has two pressure adjusting tools 33 provided on both sides or near both sides of the upper surface part 31. Therefore, it is supported by the frame 1 and the distance from the lower shell 23 is set to a required size.

The pressure adjustment tool 33 is, for example, a support fitting 35 provided on the pedestal 1,
Consisting of a screw rod 37, an adjusting fixing nut 39, a bearing 41, a fixing metal fitting 43, etc., the upper shell 19 is suspended from the frame 1 on both sides of its width and approximately in the center, and the distance from the lower shell 23 is adjusted by the pressure adjusting tools 33 on both sides. Each can be set to a desired value below the position. Therefore, the amount of reduction of the upper shell 19 relative to the lower shell 23 can be limited, and the shaft bearing 41 can prevent the filter cloth 3 from being unbalanced in the direction of travel. Further, the upper shell 19 has lowering means 45 between it and the frame 1 on a vertical plane that passes through approximately the center of the upper surface portion 31 and is parallel to the traveling direction of the filter cloth 3 and at approximately symmetrical positions with respect to the center.

The lowering means 45 can be, for example, a known pneumatic cylinder or hydraulic cylinder. As an example, the upper shell 19 can be moved by connecting two pneumatic cylinders 45 installed perpendicularly to the frame 1 to the front and rear ends of the upper surface part 31 via bearings 49 installed at the lower ends of the shafts 47, respectively. The filter cloth 3 is pressed down toward the lower shell 23 to press the filter cloth 3 within the interval set by the pressure adjuster 33.

The pressing force by the pneumatic cylinders 45 is adjusted by adjusting the air pressure from an air compressor (not shown) for each pneumatic cylinder 45 or simultaneously, thereby adjusting the pressing force between the front and rear of the upper shell 19. Balance is maintained using the bearing 41 of the tool 33 as a fulcrum, and balance in the left and right direction is maintained by the bearing 49, so that the pressing force of the entire upper shell 19 can be set to a desired value. Further, since the distance between the upper shell 19 and the lower shell 23 is set to a required value by the pressure adjusting device 33, it is possible to prevent the filter cloth 3 from being pressed more than necessary. Upper shell 19
A sealing sheet 53 made of an elastic material such as synthetic resin or rubber, and a pressure adjustment plate 55 are provided on the side surface 51 on the outlet side of the filter cloth 3.
, has a partition part 61 for pressure adjustment consisting of an adjustment stud 57, an adjustment nut 59, etc., and when the pressure adjustment plate 55 is lowered by the adjustment stud 57 and adjustment nut 59, the sealing sheet 53 A gap 6 is formed at the lower end of the side surface 51 of the upper shell 19 by strongly pressing down the lower end onto the upper surface of the filter cloth 3.
3 is almost hermetically sealed to prevent the pressure inside the upper shell 19 from decreasing and increase the pressure of the sludge S flowing into the upper shell 19. Since it can be dehydrated very effectively by pressing, the water content can be easily reduced even in Cake C, which is difficult to dehydrate.

If the pressing force is weakened by raising the pressing force adjustment plate 55, the opposite will occur, so the adjustment is made according to the magnitude of the filtration resistance of the sludge and the difficulty of dewatering the cake C. Further, the press adjustment plate 55 is fixed with a fixing screw 65 after adjustment. Partition part 6 of upper shell 19
The remaining lower portions of the side surfaces other than 1 that contact the filter cloth 3 and the upper surface of the lower shell 23 that contact the filter cloth 3 are made of sliding frames 67 and 69 made of synthetic resin or the like that have low frictional resistance with the filter cloth 3.
It is advantageous to add

The drive roll 71 pulls and circulates the filter cloth 3 from the support roll 5 through a guide roll 73 and usually one or more receiving rolls 75 for dewatering, and also pulls and circulates the filter cloth 3 through the filter cloth 3 to the press roll 7.
Drive 7.

It is preferable that the drive roll 71 is driven by a variable speed electric motor 79 so that the speed of the filter cloth 3 can be continuously variable from about 67 TL/Min to about 607 n/Min. The press roll 77 is supported by bearings 83 provided on two support arms 81 that have a bearing 80 provided on the pedestal 1 as a fulcrum.
It has a cake peeling means 85 for peeling off the cake C'' that has been transferred to the surface of the plate, and for example, a scraper or the like can be used.

The distance between the blade edge of the scraper 85 and the surface of the pressure roll 77 is less than or equal to the thickness of the cake C'' to be transferred, for example, less than 5 Trrm, preferably 37!Rln~0.5. Therefore, the distance is set to 1.0 Tfm. If the thickness of the transferred cake C'' is 2.5wn, 1.5Tfrm is peeled off and one layer is left on the surface of the press roll 77 as cake C''''. Further, below the scraper 85, there is a conveyor 87 for discharging the peeled cake C''.The press roll 77 compresses the cake C on it together with the filter cloth 3 between the receiving roll 75 and the driving roll 71. In order to dehydrate the filter cloth 3 and then peel the dehydrated cake C from the filter cloth 3 and transfer it to the surface of the pressing roll 77, a required pressing force and a diameter larger than that of the driving roll 71 and the receiving roll 75 are required. The surfaces of the drive roll 71 and the receiving roll 75 are preferably coated with rubber to increase friction or dewatering force.

The pressing force is determined by the weight of the pressing roll 77, and if necessary, the pressing force can be increased by pouring water into the pressing roll 77, which usually has a hollow cylindrical shape, or by loading weights on the two support arms 81. By doing so, the pressing force can be increased. Note that the diameter of the press roll 77 is preferably about 2 to 3.5 times that of the drive roll 71. Further, it is preferable that the press roll 77 can be raised when replacing the filter cloth 3. For example, the support arm 8
A wire or the like is connected to the tip end 89 of the roll 1, and the winding press roll 77 can be raised via a pulley 91 by a winding machine 93. In addition, the receiving roll 75 is preferably one that can be adjusted up and down in order to optimally set the position relative to the pressing roll 77 for dewatering. The cleaning device includes a cleaning water tank 95, two basket-shaped rolls 101 which are shaped like a polygonal basket and have a large gap 99 in the middle of a beam 97 that forms the framework, two sets of fountain nozzles 103, and a water tank 95. It mainly consists of a high-pressure pump 105 that pressurizes water W from a water tank (not shown), a set of squeezing rolls 107, etc. It is preferable to use ultrasonic waves for cleaning, and a fountain nozzle 103
In this case, a so-called water horn-type ultrasonic fountain nozzle 103 that draws air into the fountain nozzle and generates ultrasonic vibrations in the water is used, or a separate ultrasonic generator is installed to generate ultrasonic waves in the cleaning water tank 95. Although any of the above may be used, a normal water whistle type ultrasonic water fountain nozzle 103 is sufficient. The operation and handling of this device will be outlined below.

The sludge S from the sludge storage tank (not shown) is transferred to a pressurizing pump 13.
, the sludge is forced into the upper shell 19 through the sludge inlet 21 through the pipe 15 and the like at the required inflow speed and pressure. At that time, the pressure pump 13 is
Corresponding to the inflow velocity and injection pressure of sludge S,
Adjustment of the distance between the upper shell 19 and the lower shell 23 by the pressure adjustment tool 33, adjustment of the pressing force by the lowering means 45 consisting of a pneumatic cylinder, adjustment of the pressure of the partition part 61, adjustment of the speed of the filter cloth 3, etc. As a result, the pressure inside the upper shell 19 is maintained at a level sufficient to satisfy the filtration resistance, and the partition portion 61
The cake C formed on the filter cloth 3 can be dehydrated and discharged from the filter cloth. Further, the filtered water that has passed through the filter cloth 3 is sufficiently scraped off by the support rod 29, and is collected from the drain port 25 of the lower shell 23 into a raw water tank (not shown) and reused. The above adjustments must be made in conjunction with each other. When the conditions of the target sludge S are constant, when an increase in the throughput is desired, the inflow speed is generally increased and the speed of the filter cloth 3 is also correspondingly increased. Since an increase in filtration resistance can thereby be prevented, there is almost no need for an increase in inflow pressure and an accompanying increase in pressing force by the pressing means. Further, by increasing the pressing force of the partition portion 61, it is possible to effectively reduce the water content of the cake C to be discharged. On the other hand, increasing the speed of the filter cloth 3 is effective in reducing the filtration resistance and increasing the throughput as described above, but it also increases the water content of the produced cake C and the required power, so it is usually based on the required cake water content. It is preferable to adjust as follows. The conditions for minimizing the moisture content of the cake C that is generally generated are preferably determined by experiment for the target sludge S, but the moisture content of the cake C discharged from the partition 61 is the sludge S containing fine sand and cement. It is possible to reduce the amount to about 55% or less in the case of sludge, and it is possible to achieve the reduction to about 65% or less even when organic matter such as mud or excrement is contained. Filter cloth 3 that holds cake C on the surface
The cake C further advances and changes direction at the guide roll 73, and is pressed between the press roll 77 and the receiving roll 75 and between the drive roll 71, and the cake C on top of it is further dehydrated.

During this time, the cake C on the filter cloth 3 has a stronger adhesion force to the press roll 77 than the one to the filter cloth 3, so almost all of the cake C on the filter cloth 3 is transferred from the filter cloth 3 onto the press roll 77, for example, about 95% in the case of cement-related cake C. The above deposits and reaches the scraper 85, where it is scraped off and transferred to the conveyor 87 below.
is carried out of the device. If the blade edge of the scraper 85 and the surface of the pressure roll 77 are close to each other, almost all of the transferred cake C'' will be peeled off, but only a part of the thickness of the transferred cake C'' will be peeled off. When a part of the cake C'''' is left on the pressure roll 77, the already dehydrated cake C'' rotates once and the cake C with a high water content on the filter cloth is transferred between the guide roll 73 and the receiving roll 75. When combined with Cake C'', Cake C'' acts as a water absorption layer, and part of the moisture contained in Cake C transfers to Cake C'', which averages out the moisture content and reduces the overall moisture content. However, it has an extremely effective effect on lowering the moisture content of Cake C'' obtained by subsequent pressing and dehydration.

On the other hand, if the thickness of cake C'' is increased, it depends on the type of sludge S, but according to the experimental results, it is generally about 5 WL.
In this case, the cake C'' is easily peeled off from the surface of the pressure roll 77, so the thickness of the cake C'' left on the surface of the pressure roll 77 is practically set to 5Tfr1n or less, preferably 3Tnm or less.

Further, at 0.5wn or less, it is difficult to confirm a clear dehydration effect, but at least the effect of facilitating the transfer of Cake C on the filter cloth onto Cake C'' is clearly recognized.
Normally, the effect of reducing the dehydration rate by providing Cake C'' can be expected to be about 1% to about 5%. In the case of sludge S made of cement, it is approximately 3
5% or less, and in the case of sludge S containing organic matter, it is about 55% or less.

After passing the drive roll 71, the filter cloth 3 in the return journey
A small amount of cake residue remaining after being transferred onto the pressure roll 77 is washed away in a washing water tank 95. First, the surface of the filter cloth 3 is washed while passing through the first basket-shaped roll 101, and cake residue is removed from the gap 99 into the water, and then from the back surface of the filter cloth 3 from the first ultrasonic water fountain nozzle 103. The filter cloth 3 is washed with high-pressure water accompanied by ultrasonic waves, and the residue remaining inside the filter cloth 3 is also removed, and the generated ultrasonic waves are transmitted into the water in the washing water tank 95 to have a further effect on cleaning the filter cloth 3. Subsequently, the filter cloth 3 is washed from the back side with a second basket-shaped roll 101, and
Next, the surface of the filter cloth 3 is cleaned by the second ultrasonic fountain nozzle 103, and finally, the filter cloth 3 is dehydrated by a set of squeezing rolls 107, and the cleaning in the return stroke is completed and the filter cloth 3 is restored to a clean state. Then, it passes through the support roll 5 again, reaches the forward step, and is circulated. Further, the waste water in the washing water tank 95 is successively returned to the mud storage tank. As described above, the continuous automatic pressurized dewatering device of the present invention circulates through a belt-shaped endless filter cloth, and uses the pressurized filtration and dehydration device provided in the forward process to perform pressurized filtration of sludge and press dewatering of cake. to reach a moisture content of about 55% or less, which is practically sufficient for a cake, and
Furthermore, the cake is dehydrated by pressing with a pressure roll, and then this cake is separated from the filter cloth, transferred, and peeled off with a scraper, so the recovery rate of the cake is extremely high, and approximately 95% of the produced cake is % or more, and when a part of the cake is left on the press roll, the moisture content of the cake is about 35% or less in the case of cement-related cake C, and about 55% or less in the case of cake containing organic matter. can be reached.

In addition, the small amount of cake residue remaining on the filter cloth is thoroughly washed from the front and back surfaces of the filter cloth by the basket-shaped roll and ultrasonic fountain nozzle during the return trip, so it usually hardens within the filter cloth and is difficult to remove. Even in the case of cement-related sludge treatment, since it is washed without giving time for solidification, it is sufficiently removed and clogging is extremely unlikely to occur over a long period of time.

In particular, in the pressure filtration and dehydration equipment, filtration is always performed using a washed filter cloth as the filter cloth advances, so the cake on the filter cloth is kept relatively thin, and therefore the filtration resistance is lower than the throughput. It is possible to apply pressure to a fraction of that of a normal filter breath.

In addition, the upper shell is held at approximately the center of both sides in the direction of travel of the filter cloth by a pressure adjustment device to limit its descent.
Since this is used as a fulcrum and is pressed forward and backward in the direction of travel by the rolling down means, there is no fear that the increased pressing force will directly press the filter cloth and cause an increase in friction during traveling, and the necessary pressing force is applied. In addition, even when increasing the pressing force of the partition and lowering the moisture content of the cake, it is easy to maintain the balance of the pressing force by adjusting the pressing force of the pressing means located at the front and rear in the direction of movement. It is. Therefore, this device not only does not require the use of filter presses, etc., which are expensive and have large maintenance costs, but also does not require a sedimentation tank, and only requires a small sludge storage tank to temporarily store sludge. It is sufficient to pressurize the sludge at about 1k9/c even for sludge such as mud or excrement, which has relatively high filtration resistance. It is sufficient to use the pressure pump described below, and the moisture content of the final cake recovered from the pressure roll can be approximately comparable to that of a conventional filter press.

Also, since it is a continuous automatic device, it is easy to handle. Both can reduce labor costs, and since it can be assembled into a single frame, it not only occupies a small area when permanently installed, but also can be loaded into a car for transportation. Joint use of several business offices will also become a reality.

The continuous automatic pressurized dewatering device of the present invention not only has excellent functional effects, but also has a relatively simple structure, so it can be supplied at low cost, and its maintenance costs are low. It is extremely useful as a pollution prevention device and can contribute to its widespread use.
