Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, and in particular to a vehicle-mounted mobile integrated sludge dehydration and filter pressing device. Background Art

[0002] Sludge treatment is an important part of the sewage treatment process. Its main purpose is to reduce the volume of sludge, reduce the water content, and make it meet the standards for disposal or reuse. At present, one of the commonly used sludge dewatering equipment is the sludge dewatering filter press, which separates the water in the sludge through physical pressure to achieve sludge reduction and resource utilization. In order to carry out sludge treatment on site, the filter press and the mobile platform equipment are often combined to form a vehicle-mounted filter press, which is convenient for the transfer of the filter press to a designated place for work.

[0003] In a traditional sludge dewatering filter press, sludge is injected between the filter plates through a feed pump. As the sludge is injected, it clings to the filter cloth on the filter plates. Subsequently, more sludge is continuously injected into the gap between two adjacent filter plates. In this process, the sludge will squeeze the filter cloth, causing it to deform. After that, with the long-term use of the filter cloth, the deformed filter cloth is not easy to automatically restore to a flat state. In this state, some sludge impurities are likely to remain on the filter cloth, affecting the subsequent dewatering process. At the same time, the deformation of the filter cloth will cause uneven distribution of the filter cake, affecting the dewatering effect and the quality of the filter cake. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings of the embodiments will be briefly introduced below. Obviously, the drawings in the following description only relate to some embodiments of the present invention, but are not intended to limit the present invention.

[0019] Example 1: A vehicle-mounted integrated sludge dewatering filter press device, referring to Figure 1-Figure 4 As shown in Figure 6, it includes: a filter press body 1; a plurality of filter press units, all of which are arranged on the filter press body 1, and the filter press units are used to treat sludge; the filter press unit includes: a filter plate 12, a filter cloth 13, a uniformly distributed sliding frame 15 and an adjustment mechanism; the filter plate 12 is installed on the filter press body 1, and the filter plate 12 is provided with two symmetrically distributed grooves 121; an annular groove 122 and a sealing strip 123 are respectively provided on both sides of the filter plate 12, and the center of the annular groove 122, the center of the sealing strip 123 and the center of the adjacent groove 121 are all located on the same straight line; the filter cloth 13 is installed on the filter plate 12, and the filter cloth 13 covers the two grooves 121, and a cylindrical hole 131 for sludge circulation is provided in the middle of the filter cloth 13; the uniformly distributed sliding frames 15 are all slidably arranged on the filter plate 12, and the sliding frames 15 and Springs are installed between the filter plates 12, and the sliding frame 15 is fixedly connected to the outer edge of the filter cloth 13. The sliding frame 15 applies circumferential stretching to the filter cloth 13 under the elastic action of the connected springs, so as to keep the filter cloth 13 flat; an adjusting mechanism is arranged on the filter plate 12, and the adjusting mechanism is used to control the movement of the sliding frames 15 evenly distributed on the filter plate 12; the filter plate 12 is provided with two liquid guide grooves 124, and the liquid guide grooves 124 are located at the lower part of the adjacent grooves 121. The filter plate 12 is provided with evenly distributed through holes 125, and the liquid guide grooves 124 are connected to the adjacent through holes 125. The filter plate 12 is fixedly connected with a drain pipe 126, and a valve is installed on the drain pipe 126, and the drain pipe 126 is connected to the adjacent through hole 125; the diameters at both ends of the through hole 125 are smaller than the middle diameter thereof, so as to guide the liquid to flow into the adjacent drain pipe 126.

[0020] In the above scheme, the filter press body 1 is provided with a control system (for monitoring and controlling the operation process of the entire filter press), a hydraulic system (for providing a clamping force to press the multiple filter plates 12 tightly together), a feeding system (for feeding sludge or other materials to be processed into the gaps between the filter plates 12), etc., all of which are prior arts. At the same time, the integrated composition of the above structure facilitates the installation of the device on a transport vehicle, facilitates the device to travel back and forth between multiple sites for work, and improves the working flexibility of the device.

[0021] A cylindrical sleeve is provided in the middle of the filter plate 12. When two adjacent filter plates 12 are attached, the cylindrical sleeves in the middle of the two filter plates 12 do not touch each other, so that the sludge can pass through the cylindrical hole 131 to fill the gap between the two adjacent filter cloths 13. A silicone pad is provided on the bottom surface of the groove 121, and the surface of the silicone pad is provided with evenly distributed protrusions (see attached Figure 3 As shown), the silicone pad is used to limit excessive deformation of the filter cloth 13, and the gaps between the protrusions on the silicone pad are used to guide the flow of the filtered liquid.

[0022] In the initial state, the spring connected to the sliding frame 15 is in a compressed state, and eight evenly distributed sliding frames 15 are arranged on each filter plate 12, wherein the sliding frame 15 clamps and fixes the adjacent filter cloth 13 by tightening the bolts. The setting of the liquid guide groove 124 and the through hole 125 is used to guide the flow of liquid to avoid the liquid from re-contacting the adjacent filter cloth 13 after aggregation, thereby avoiding the liquid from re-mixing with the sludge block and improving the dehydration efficiency of the sludge. After the two adjacent filter plates 12 are fitted together, when the two adjacent filter press units are in contact, the two filter cloths 13 between the two are in contact and form a filter chamber. When the sludge treatment operation is performed, the sludge enters the filter chamber for filter pressing operation to discharge the moisture in the sludge.

[0023] Specific working principle: The hydraulic system on the filter press body 1 works to press all the filter plates 12 tightly together, and then the feeding system injects the sludge to be treated between the tightly fitted filter plates 12, wherein the sludge passes through the cylindrical holes 131 on all the filter cloths 13 and fills the gaps between two adjacent filter cloths 13 in turn. During the sludge injection process, the sludge is blocked by the filter cloth 13, and the sludge and the filter cloth 13 are squeezed, so that the water in the sludge passes through the filter cloth 13 and falls into the adjacent liquid guide groove 124, and then the water is discharged through the adjacent through holes 125 and the adjacent drainage pipe 126, completing the sludge dehydration treatment. After the filter cake between the adjacent filter cloths 13 reaches a specified thickness, the operator The operator turns off the feeding system on the filter press body 1 and controls the hydraulic system to work in reverse and reset, and then controls all the filter plates 12 to move in sequence. Even if the adjacent filter plates 12 are separated, during the filter plate separation process, the sludge filter cake between the filter cloths 13 on the two filter plates 12 falls into the collecting shell. After the filter plates 12 are separated, the circumferentially distributed sliding frames 15 pull the filter cloth 13 to keep it flat under the elastic force of the springs connected to the sliding frames 15, which accelerates the separation of the sludge thereon. At the same time, the flat filter cloth 13 is convenient for manual and regular cleaning of the sludge impurities remaining on the filter cloth 13, thereby extending the service life of the filter cloth 13. The above operation can be repeated when the sludge dehydration operation is performed again.

[0024] Reference Figure 2 , Figure 4 and Figure 5 As shown, the adjustment mechanism includes: a fixed shell 2, which has multiple parts, all of which are fixedly connected to adjacent filter plates 12, and two first sliding frames 21 symmetrically distributed are provided in the fixed shell 2 for limited sliding. A spring is installed between the two adjacent first sliding frames 21, and the first sliding frame 21 is provided with an inclined surface, and the inclined surface of the first sliding frame 21 is in contact with the adjacent sliding frame 15.

[0025] The first sliding frame 21 is moved so that the upper inclined surface of the first sliding frame 21 squeezes the adjacent sliding frame 15, so that all the sliding frames 15 on the same filter plate 12 are close to each other, and the filter cloth 13 fixed by the sliding frame 15 is gradually relaxed, so that the filter holes on the filter cloth 13 are in a state of keeping the same size and fitting into the adjacent grooves 121, thereby realizing the dehydration of a certain amount of sludge between the two adjacent filter cloths 13. After the sludge dehydration is completed, the operation of separating the filter plates 12 is repeated. In this process, under the elastic force of the spring between the two adjacent first sliding frames 21, the two adjacent first sliding frames 21 move in the opposite direction to reset and gradually release the limit on the adjacent sliding frame 15. The sliding frame 15 is reset under the elastic force of the adjacent spring and re-stretches the adjacent filter cloth 13 to be tight and flat, so as to facilitate the subsequent cleaning of the sludge impurities on the filter cloth 13.

[0026] Example 2: Based on Example 1, refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, it also includes: a blocking mechanism, which has a plurality of them and is respectively arranged on adjacent filter plates 12, and the blocking mechanism is used to control the deformation range of adjacent filter cloths 13. The blocking mechanism includes: a plurality of sliding blocks 3, which are all slidably arranged on adjacent filter plates 12, and the sliding blocks 3 located on the same horizontal plane are slidably arranged together with two symmetrically distributed second sliding frames 31, and the two adjacent second sliding frames 31 are respectively located on both sides of the adjacent filter plates 12, and a tension spring is installed between the two adjacent second sliding frames 31, and the second sliding frames 31 are used to scrape off water drops attached to the adjacent filter cloths 13; a plurality of first elastic telescopic rods 32, which are respectively fixed between the upper and lower adjacent sliding blocks 3, and the filter plate 12 is fixed with a plurality of guide frames 33, the number of the guide frames 33 is the same as the number of the second sliding frames 31, and the guide frames 33 are in contact with the adjacent second sliding frames 31; a plurality of limiting components, which are respectively arranged on adjacent filter plates 12, and the limiting components are used to limit the movement of the corresponding second sliding frames 31.

[0027] In the above scheme, the first elastic telescopic rod 32 is composed of a shell and a tension spring that slide against each other. In the initial state, the second sliding frame 31 is located on the adjacent guide frame 33, so that the second sliding frame 31 fits the adjacent filter cloth 13. The guide frame 33 is divided into three sections, namely a horizontal section, a vertical section and an inclined section. The inclined section of the guide frame 33 is used to squeeze the adjacent second sliding frame 31 to move, and the tension spring between the two adjacent second sliding frames 31 is always in a stretched state.

[0028] During the sludge dewatering process, as all the filter plates 12 are fitted together, the second sliding frame 31 squeezes the adjacent filter cloths 13 to make the two adjacent filter cloths 13 fit together, and then as the sludge is gradually injected into all the filter plates 12 and the filter cloths 13, the sludge first fills the filter chamber between the upper and lower adjacent second sliding frames 31, and then as the sludge is gradually injected, the sludge gradually fills the filter chamber composed of the two adjacent filter cloths 13. During the filling process, the sludge simultaneously squeezes the two adjacent second sliding frames 31, so that the upper and lower adjacent second sliding frames 31 are separated from each other, and the two stretch the adjacent first elastic telescopic rods 32. In this process, the second sliding frame 31 hinders the movement of sludge, so that the sludge gradually fills the filter chamber composed of the adjacent filter cloths 13, and controls the compactness of the sludge between the filter chambers to remain relatively uniform, thereby ensuring the constant amount of sludge processed by the device at a single time and ensuring the uniformity of the sludge dewatering effect.

[0029] Reference Figure 7 and Fig. 9As shown, the limit assembly includes: a plurality of ratchet bars 4, all of which are slidably set on adjacent filter plates 12, and the ratchet bars 4 are fixedly connected to adjacent sliding frames 15; a plurality of second elastic telescopic rods 41, which are respectively fixedly connected to the sliding blocks 3 close to the ratchet bars 4, and the second elastic telescopic rods 41 are fixedly connected to the limit blocks 42, and the ratchet bars 4 are used to limit the movement of the adjacent limit blocks 42.

[0030] In the above scheme, after all the filter plates 12 are fitted together, the sliding frame 15 moves to drive the adjacent spine 4 to move, and the spine 4 moves to contact the adjacent limit block 42. Later, when the sludge fills the filter chamber composed of two adjacent filter cloths 13, the adjacent second sliding frame 31 moves to drive the adjacent sliding block 3 and the adjacent limit block 42 and the second elastic telescopic rod 41 to move, wherein the limit block 42 moves along the adjacent spine 4, and the second elastic telescopic rod 41 performs corresponding telescopic changes. During this process, the contact between the spine 4 and the adjacent limit block 42 is used to limit the reverse movement of the limit block 42. After the quantitative sludge is dehydrated, the above operation is repeated to separate the adjacent The filter plate 12, wherein after two adjacent filter plates 12 are separated, the sliding frame 15 repeats the above-mentioned operation to reset, and the corresponding sliding frame 15 resets to drive the adjacent spine 4 to move, and the spine 4 moves to release the limit on the adjacent limit block 42, and the first elastic telescopic rod 32 is subjected to the required pulling force after the extension of the first elastic telescopic rod 32, and the first elastic telescopic rod 32 is reset and drives the two adjacent sliding blocks 3 to reset, and the sliding block 3 is reset to drive the adjacent second sliding frame 31 to reset, and the second sliding frame 31 is reset and moves along the adjacent first elastic telescopic rod 32. In this process, the second sliding frame 31 scrapes off the water droplets attached to the adjacent filter cloth 13, so that the water droplets drip along the adjacent second sliding frame 31 into the adjacent liquid guide groove 124 and drain away.

[0031] Example 3: Based on Example 2, refer to Figure 1 and Figure 7 As shown, it also includes: a driving mechanism, which is arranged on the filter press body 1, and the driving mechanism is used to control the corresponding first elastic telescopic rod 32 to telescope, and the driving mechanism includes: a first conduit 5, which is fixed to the side wall of the filter press body 1; a second conduit 51, which has a plurality of conduits, which are respectively embedded in adjacent filter plates 12, and the two ends of the second conduit 51 are respectively fixedly connected to and communicated with the first conduit 5 and the chamber of the adjacent first elastic telescopic rod 32.

[0032] In the above scheme, the first conduit 5 is connected to the existing air pump (the air pump is the existing technology, which is shown in the figure). The operator controls the air pump to work through the control system. The air pump extracts the gas in the first conduit 5, so that negative pressure is formed in the first conduit 5, in all the first conduits 5 and in the chamber of the corresponding first elastic telescopic rod 32. The negative pressure in the chamber on the first elastic telescopic rod 32 hinders the extension of its telescopic end, that is, the hindering force of the second sliding frame 31 on the sludge is increased, so that the compactness of the sludge in the filter chamber composed of two adjacent filter cloths 13 is increased, that is, large-particle sludge impurities are squeezed and drained with higher pressure. When the device filters sludge of different components, the compactness of the sludge in the filter chamber is controlled by controlling the size of the negative pressure in the first conduit 5, thereby improving the applicability of the device.

[0033] Example 4: Based on Example 3, refer to Figure 4 , Fig. 9 and Fig.10 As shown, it also includes: a vibration mechanism, which has multiple components and is respectively arranged on adjacent filter plates 12, and the vibration mechanism is used to control the reciprocating movement of the corresponding second sliding frame 31, and the vibration mechanism includes: a telescopic push rod 6, which has multiple components and is fixedly connected to the adjacent filter plate 12, and the chamber of the telescopic push rod 6 is fixedly connected to and communicated with the adjacent second conduit 51; a rack frame 61, which has multiple components and is respectively fixedly connected to the telescopic ends of the adjacent telescopic push rods 6; a fixed block 62, which has multiple components and is respectively fixedly connected to the adjacent filter plate 12; a rotating frame 63, which has multiple components and is rotatably arranged on the adjacent fixed blocks 62, and the rotating frame 63 is fixedly connected with a gear meshing with the adjacent rack frame 61.

[0034] In the above scheme, there are four telescopic push rods 6, which are composed of a shell and a cylindrical rod. The cylindrical rod is located in the shell and slides. The rotating frame 63 is wavy. There are four rotating frames 63 and eight fixed blocks 62 on each filter plate 12. The above number is schematically shown in the figure. The specific number can be set accordingly according to the actual situation. During the sludge dewatering operation, combined with the control of the pressure change in the first conduit 5, the sludge is filled with a certain degree of compactness in the filter chamber composed of two adjacent filter cloths 13. In this process, the negative pressure in the first conduit 5 causes the cylindrical rods on the adjacent telescopic push rods 6 to drive the adjacent rack racks 61 to move, and the rack racks 61 move through the adjacent gears to make the adjacent rotating frames 63 in the adjacent Fig. 9 In the state shown in , the rotating frame 63 does not contact the adjacent filter cloth 13, and the above operation is repeated to dehydrate the sludge.

[0035] After the sludge dehydration treatment is completed, the above operation is repeated to separate the two adjacent filter plates 12, and then the control system controls the air pump to inject gas into the first conduit 5 to increase the pressure in the first conduit 5. Under the action of the high pressure, the cylindrical rod on the adjacent telescopic push rod 6 is reset, that is, the rotating frame 63 swings in the opposite direction, and the rotating frame 63 swings to contact and squeeze the adjacent second sliding frame 31. In the subsequent resetting process of the sliding block 3, the sliding block 3 drives the adjacent second sliding frame 31 to move along the adjacent rotating frame 63. Under the wave-shaped guiding effect of the rotating frame 63, the second sliding frame 31 reciprocates during the reciprocating process. The reciprocating rocking of the second sliding frame 31 squeezes the adjacent filter cloth 13 to rock, and the rocking of the filter cloth 13 accelerates the detachment of the sludge impurities attached thereto, thereby ensuring the stability of the subsequent filtering effect of the filter cloth.

[0036] Reference Fig. 9 and Fig.10 As shown, the rotating frame 63 is slidably provided with a sliding column 7, a tension spring is installed between the sliding column 7 and the adjacent fixed block 62, and the rotating frame 63 is provided with a plurality of blind holes. The sliding column 7 is inserted into the corresponding blind holes on the adjacent rotating frame 63 to limit the rotation of the corresponding rotating frame 63.

[0037] In the above scheme, the end of the sliding column 7 is hemispherical, and two hemispherical blind holes are provided on the rotating frame 63. When two adjacent filter plates 12 are in contact, the rotating frame 63 is in the adjacent Fig. 9 , at this time, the sliding column 7 is inserted into the corresponding blind hole on the adjacent rotating frame 63, limiting the movement of the rotating frame 63, so that the second sliding frame 31 always moves along the vertical section of the adjacent guide frame 33, that is, ensuring that the second sliding frame 31 always keeps blocking the sludge. When the two adjacent filter plates 12 are in a separated state, as the pressure in the first conduit 5 increases, the rotating frame 63 swings to contact the adjacent second sliding frame 31. At this time, the sliding column 7 is inserted into another blind hole on the adjacent rotating frame 63, so that the rotating frame 63 always keeps squeezing the adjacent second sliding frame 31 during this process, that is, ensuring that the second sliding frame 31 squeezes the adjacent filter cloth 13 to reciprocate and shake stably during the resetting process, thereby accelerating the separation of sludge impurities attached to the filter cloth 13.

[0038] While the disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised which do not depart from the scope of the invention.
