DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0054] Embodiment one

[0055] Reference Figures 1-28 The sludge filter-pressing system for water treatment shown in the figure comprises a support assembly 2, a flocculation mechanism 3 for stirring flocculants to preliminarily discharge sludge water, a filter-pressing assembly 4 for further discharging sludge water in cooperation with the flocculation mechanism 3, and a driving assembly 1 provided at the bottom of the support assembly 2 for providing power for the flocculation mechanism 3 and the filter-pressing assembly 4.

[0056] The filter-pressing assembly 4 comprises a feeding mechanism 42 for conveying sludge, a water-removing mechanism 44 for preliminarily draining water from the sludge in cooperation with the feeding mechanism 42, a water-filtering mechanism 43 for subsequent water draining in cooperation with the feeding mechanism 42, and a sludge-pressing mechanism 41 for extruding sludge in cooperation with the feeding mechanism 42.

[0057] It is worth mentioning that, in use, the user sends sludge into the support assembly 2, and then the filter-pressing assembly 4 provides power to drive the flocculation mechanism 3 to run to separate the mixed flocculants from the sludge, and the separated water is discharged through the interlayer inside the support assembly 2. The flocculation mechanism 3 preliminarily processes the sludge to process a large amount of sludge in the shortest time, so that the flocculation mechanism 3 and the filter-pressing assembly 4 are blockized to increase the processing amount of the sludge.

[0058] And the running of the flocculation mechanism 3 extrudes the sludge into the filter-pressing assembly 4, and the feeding mechanism 42 conveys the sludge containing a large amount of water upwards, and because the water-removing mechanism 44 is arranged in the opposite direction of the conveying direction of the feeding mechanism 42, it causes resistance to the upward extrusion of the sludge, so that a large amount of water is filtered and discharged by the water-removing mechanism 44 when the sludge is extruded upwards, and the water-removing mechanism 44 cooperates with the driving assembly 1 to further remove water from the sludge. The sludge preliminarily removed by the water-removing mechanism 44 continuously moves upwards with the movement of the feeding mechanism 42, and the resistance increases as the height of the sludge increases. At this time, the water-filtering mechanism 43 is arranged at the middle and upper part of the support assembly 2 and has a peculiar shape, which causes greater resistance to the upward movement of the sludge. As the resistance to the upward movement of the sludge increases and continuously impacts the water-filtering mechanism 43, the water in the sludge is extruded into the water-filtering mechanism 43, and the water discharged from the water-filtering mechanism 43 flows into the interlayer arranged inside the support assembly 2 and is then discharged.

[0059] With the movement of the sludge with the feeding mechanism 42 continues to move up, when the sludge contacts the mud pressing mechanism 41, because the mud pressing mechanism 41 and the support assembly 2 are provided with a certain gap to the discharged sludge causes greater resistance, and the special setting of the mud pressing mechanism 41 and the feeding mechanism 42 cooperate to make the sludge extrusion discharge resistance further increase, so that the filter mechanism 43 can discharge more water in the sludge, the overall filtering process of the filter pressing assembly 4 and the flocculation mechanism 3 form a complete sludge filter pressing system, the flocculation mechanism 3 can pretreat a large amount of sludge, thereby reducing the working pressure of the subsequent filter pressing assembly 4.

[0060] Wherein, the driving assembly 1 includes a difference gear 16, a driving motor 12, a pump 13 and a bottom cover 11 sleeved on the outer surface of the support assembly 2, the delivery end of the driving motor 12 is fixedly connected with a driving gear 17, the driving gear 17 is engaged with the difference gear 16, and the driving gear 17 and the difference gear 16 are arranged at the bottom of the support assembly 2.

[0061] Wherein, the flocculation mechanism 3 includes a support rod 32 and a mounting frame 34, the outer surface of the support rod 32 is provided with a spiral plate 31, the outer surface of the support rod 32 is provided with a scraper 33 at the bottom, the outer surface of the support rod 32 is sleeved with a threaded ring 37, and the threaded ring 37 is located at the upper part of the stirring disc 36, the bottom of the mounting frame 34 is provided with a mounting ring 311, the outer surface of the mounting ring 311 is sleeved with a filter cover 35, the inner wall of the filter cover 35 is provided with a support ring 38, and the inner wall of the mounting frame 34 is provided with a fixing ring 312 for fixing the position of the support ring 38;

[0062] The mounting frame 34 is sleeved on the outer surface of the hollow cylinder 26, and the spiral plate 31 is attached to the inner wall of the hollow cylinder 26, the bottom of the support rod 32 penetrates the stirring cylinder 21 and is fixedly connected with the driving gear 17, and the stirring disc 36 is attached to the inner wall of the stirring cylinder 21.

[0063] It is worth noting that in use, the user starts the driving motor 12 to drive the driving gear 17 to rotate, and the driving motor 12 drives the driving gear 17 to rotate at the same time also drives the support rod 32 to rotate, because the top of the support rod 32 is provided with a rectangular slot, and the rectangular slot is connected with the stirring disc 36 inside, so when the support rod 32 rotates, it can drive the stirring disc 36 to rotate, and the rotation of the stirring disc 36 can continuously stir the sludge entering the inside of the stirring cylinder 21, so that the sludge and the added flocculant can be quickly stirred and reacted, and the sludge after stirring and reaction will appear clumping and water begins to separate, with the continuous rotation of the support rod 32 will drive the spiral plate 31 to rotate, with the rotation of the spiral plate 31 can drive the clumped sludge to rotate into the hollow cylinder 26.

[0064] Further, the support assembly 2 comprises a stirring cylinder 21 and an extrusion cylinder 20, the extrusion cylinder 20 is fixedly installed on the outer surface of the stirring cylinder 21, and the diameter of the extrusion cylinder 20 is smaller than that of the stirring cylinder 21, the outer surface of the extrusion cylinder 20 is provided with a drain pipe 23 at the upper portion, the bottom of the extrusion cylinder 20 is provided with a filter-pressing cylinder 25, the bottom of the stirring cylinder 21 is provided with a hollow cylinder 26, the outer surface of the extrusion cylinder 20 and the stirring cylinder 21 are both provided with a drain hole 22 at the bottom, and the water outlet pipe 15 is fixedly installed in the drain hole 22, the filter-pressing cylinder 25 is provided with a communication pipe 29 between the filter-pressing cylinder 25 and the hollow cylinder 26, the filter-pressing cylinder 25 communicates with the inside of the hollow cylinder 26 through the communication pipe 29, and the communication pipe 29 is fixedly installed in the communication hole 27.

[0065] When the sludge agglomerates are separated from the water, the thrust caused by the continuous rotation of the spiral plate 31 makes the sludge pass through the filter cover 35 for preliminary filtration, the filter cover 35 can separate and discharge the water in the sludge into the interlayer between the hollow cylinder 26 and the stirring cylinder 21, because the installation frame 34 is closely combined with the inner wall of the stirring cylinder 21, the sludge in the stirring cylinder 21 will not be mixed with the water filtered from the filter cover 35 during the stirring process, and the material of the filter cover 35 is a sludge-water separation screen cloth in the prior art, which can block the agglomerated sludge to preliminarily filter the water in the sludge, and because the sludge agglomerated by the flocculant is heavy and will quickly sink, the agglomerated sludge can be transported into the inside of the hollow cylinder 26 by the continuous rotation of the spiral plate 31;

[0066] The continuous rotation of the support rod 32 makes the scraper 33 rotate, because the scraper 33 is arranged at the bottom of the hollow cylinder 26, and the scraper 33 is provided with two parts which can quickly extrude the sludge in the hollow cylinder 26 into the inside of the communication pipe 29 by cooperating with the rotation of the spiral plate 31, and the water in the interlayer between the hollow cylinder 26 and the stirring cylinder 21 will pass through the drain hole 22 into the water outlet pipe 15.

[0067] It is worth noting that when the support rod 32 is driven to rotate by the driving motor 12 during use, the support rod 32 will drive the stirring disc 36 to rotate, and the stirring disc 36 will continuously stir the sludge in the stirring cylinder 21 and the added flocculant, so that the sludge is coagulated into agglomerates and separated from the water, then the agglomerated sludge is stirred to the bottom by the continuous rotation of the spiral plate 31, and the separated water is preliminarily filtered by the filter cover 35 by the operation of the spiral plate 31, which can greatly reduce the water content in the sludge during the sludge filter-pressing process, and the sludge stirred to the bottom by the spiral plate 31 will be extruded into the filter-pressing assembly 4 for final filter-pressing treatment, so that the entire filter-pressing system is divided into two working modules, which not only can reduce the workload of each working module, but also can process a large amount of sludge at the same time by cooperating with the filter-pressing assembly 4.

[0068] Embodiment Two

[0069] The present embodiment combines the feeding mechanism 42, the support assembly 2 and the water removal mechanism 44 proposed in Embodiment One, and provides further technical solutions of the feeding mechanism 42, the support assembly 2 and the water removal mechanism 44.

[0070] In order to enable the sludge to be extruded quickly, a feeding mechanism 42 as shown in the drawings is provided. Figure 21 and 22 The feeding mechanism 42 includes a fixed rod 422, and a sleeve 424 is arranged on the outer surface of the fixed rod 422 at the lower part of a conveying plate 421. The outer surface of the fixed rod 422 is provided with two groups of annularly arranged pushing blades 425.

[0071] The bottom of the extrusion cylinder 20 and the stirring cylinder 21 are both provided with a communication hole 27, and the extrusion cylinder 20 is in communication with the inside of the stirring cylinder 21 through the communication hole 27. The outer surface of the filter pressing cylinder 25 is provided with a plurality of annularly arranged connection holes 212 and mounting holes 211, and the mounting holes 211 are located below the connection holes 212. The outer surface of the hollow cylinder 26 is provided with a retaining ring 28 at the upper part.

[0072] It is worth noting that when the sludge is extruded from the hollow cylinder 26 into the communication pipe 29, the sludge will enter the filter pressing cylinder 25 through the communication pipe 29 under the continuous extrusion of the scraper 33 and the spiral plate 31. When the driving motor 12 drives the driving gear 17 to rotate, the differential gear 16 will also rotate because the driving gear 17 is engaged with the differential gear 16. The rotation of the differential gear 16 will drive the fixed rod 422 to rotate, and because the diameter of the differential gear 16 is smaller than that of the driving gear 17, the rotation speed of the differential gear 16 will be greater than that of the driving gear 17, so that the fixed rod 422 rotates faster.

[0073] The bottom of the fixed rod 422 is fixedly connected with the differential gear 16 through the extrusion cylinder 20. The conveying plate 421 and the two groups of pushing blades 425 are located inside the filter pressing cylinder 25, and the conveying plate 421 and the pushing blades 425 are in close contact with the inner wall of the filter pressing cylinder 25. The support column 413 is located inside the limiting hole 423.

[0074] Further, when the fixed rod 422 rotates, the pushing blades 425 will also rotate. Because the pushing blades 425 are in close contact with the inner wall of the filter pressing cylinder 25, and the pushing blades 425 are installed at an angle of thirty degrees, the pushing blades 425 will push the sludge extruded into the filter pressing cylinder 25 upward when they rotate, and the surface of the pushing blades 425 is in the shape of an arc, which will generate a greater pushing force when the sludge is extruded.

[0075] Wherein, in order to quickly remove the water in the sludge is set as Figures 25-28 The water removal mechanism 44 shown in the figure, the water removal mechanism 44 includes the installation pipe 444, the outer surface of the installation pipe 444 is provided with a plurality of annular array distribution of the link frame 446, the two sides of the plurality of link frame 446 are provided with two ceramic filter 445, the inside of the plurality of link frame 446 is provided with the air nozzle 441, and the bottom of the plurality of air nozzle 441 is connected with the hollow ring 442, the outer surface of the hollow ring 442 is provided with the drain pipe 443;

[0076] Wherein, when the above-mentioned push leaf 425 rotates and pushes the caked sludge upwards, because the link frame 446 is arranged between the two groups of push leaves 425, and the inclination angle of the rotation of the link frame 446 is opposite to that of the push leaf 425, the sludge is extruded when it is pushed upwards, so that the sludge is extruded, ceramic filter 445, so as to generate resistance to the upward pushing of the sludge, and when the sludge extrudes the ceramic filter 445, the water in the sludge will pass through the ceramic filter 445 to further remove the water in the sludge, and the ceramic filter 445 belongs to the existing manufacturing process, mainly through the control of temperature and the use of different materials, so that the gap between the filter plates is generated, so that the water molecules can pass through, thereby achieving the filtering effect.

[0077] The water inlet pipe 14 is fixedly connected to the inlet end of the pump 13, the water outlet pipe 15 is fixedly connected to the outlet end of the pump 13, the water outlet pipe 15 penetrates the inside of the support assembly 2, and one end of the water outlet pipe 15 extends to the outside of the bottom cover 11.

[0078] The installation pipe 444 is sleeved on the outer surface of the fixed rod 422, and the installation pipe 444 is located between the two groups of push leaves 425, the plurality of link frames 446 correspond one by one to the positions of the mounting holes 211, the hollow ring 442 is sleeved on the outer surface of the filter press cylinder 25, and one end of the drain pipe 443 penetrates the extrusion cylinder 20 and is fixedly connected with the water inlet pipe 14.

[0079] Wherein, when the above-mentioned sludge flows upwards and extrudes the ceramic filter 445, part of the water will pass through the ceramic filter 445 and be discharged, and at this time the pump 13 will also drive the air to be sucked through the water inlet pipe 14, the water filtered through the ceramic filter 445 will enter the hollow ring 442 through the air nozzle 441, then enter the drain pipe 443 through the hollow ring 442, and finally flow into the water inlet pipe 14 through the drain pipe 443, the water entering the pump 13 will also be discharged through the water outlet pipe 15, and because the operation of the pump 13 will generate a large suction force, the pressure in the link frame 446 will decrease to enable the water to be quickly discharged through the ceramic filter 445, thereby quickly discharging the water in the sludge, because the push leaf 425 continuously pushes the sludge upwards, the sludge will not be continuously adsorbed on the surface of the ceramic filter 445 during the process of discharging water, ensuring that the subsequent continuous drainage of the sludge will not be hindered.

[0080] It is worth mentioning that after the sludge is preliminarily treated by the flocculation mechanism 3, the sludge will enter the filter cylinder 25 through the communication pipe 29 under the continuous extrusion of the scraper 33 and the spiral plate 31, the pushing blade 425 will also rotate to push the sludge extruded into the filter cylinder 25 upwards, and the surface of the pushing blade 425 is arc-shaped, which can generate a large pushing force when rotating and extruding the sludge. When the sludge is pushed upwards, the ceramic filter sheet 445 is extruded, because the special angle of the ceramic filter sheet 445 generates resistance to the upward pushing of the sludge, so that the ceramic filter sheet 445 can quickly filter the water in the sludge, and the air vent 441 and the hollow ring 442 cooperate with the pump 13 to increase the filter pressing effect on the sludge.

[0081] Embodiment three

[0082] The support assembly 2, the feeding mechanism 42, the water filtering mechanism 43 and the mud pressing mechanism 41 provided in the embodiments one and two are combined, and the embodiment provides further technical solutions of the feeding mechanism 42, the water filtering mechanism 43 and the mud pressing mechanism 41.

[0083] It is worth mentioning that in order to make the extruded sludge drier, the water filtering mechanism 43 shown in Figure 23 and 24 is provided, which includes a position control ring 431 and a sleeve 433. The outer surfaces of the sleeve 433 and the position control ring 431 are provided with a plurality of annularly arranged clamping grooves 434, and the interiors of the plurality of clamping grooves 434 are provided with filter leaves 432.

[0084] The sleeve 433 is sleeved on the outer surface of the fixed rod 422, and the sleeve 433 is located below the sleeve ring 424. The position control ring 431 is located in the interior of the filter cylinder 25, and the plurality of filter leaves 432 correspond to the positions of the connection holes 212 one by one.

[0085] It is worth mentioning that after the sludge is preliminarily filtered by the ceramic filter sheet 445, the sludge filtered by the ceramic filter sheet 445 is continuously pushed upwards by the continuous rotation of the pushing blade 425. When the sludge moves upwards and pushes the filter leaves 432, a large resistance is generated because the filter leaves 432 are wave-shaped and are placed obliquely. The material of the filter leaves 432 is the same as that of the ceramic filter sheet 445. When the sludge extrudes the filter leaves 432, the water in the sludge is isolated and flows into the interlayer between the filter cylinder 25 and the extrusion cylinder 20 through the gaps between the filter leaves 432, and then the filtered water flows into the water outlet pipe 15 through the drain hole 22.

[0086] The outer surface of the fixed rod 422 is provided with a conveying plate 421 at the upper part, and the top of the fixed rod 422 is provided with a limiting hole 423.

[0087] Further, after the sludge is filtered by the filter leaf 432, the continuous rotation of the fixed rod 422 will drive the continuous rotation of the conveying plate 421, and the rotation of the conveying plate 421 can continuously push the sludge filtered by the filter leaf 432 upwards. Because the setting position of the filter leaf 432 and the outer diameter thickness of the conveying plate 421 are greater than the inner diameter thickness of the conveying plate 421, a greater resistance will be generated when the conveying plate 421 pushes the sludge, so that the resistance of the sludge extruding the filter leaf 432 is increased, thereby achieving a better filtering effect.

[0088] The sludge pressing mechanism 41 comprises a conical plate 412, and a support column 413 is arranged at the bottom center of the conical plate 412. A connecting rod 414 is fixedly installed at the top of the conical plate 412, and a support plate 411 is sleeved on the outer surface of the connecting rod 414. Two adjusting plates 24 are symmetrically arranged on the top of the outer surface of the extrusion cylinder 20.

[0089] Further, when the conveying plate 421 continuously rotates to push the sludge upwards, because the upper part of the filter pressing cylinder 25 is provided with the conical plate 412, the movement of the sludge generates a greater resistance. The user can control the gap between the conveying plate 421 and the filter pressing cylinder 25 by adjusting the threads between the support plate 411 and the adjusting plate 24. The diameter of the conical plate 412 is greater than the diameter of the filter pressing cylinder 25, so that the sludge can be quickly extruded when being conveyed upwards by the conveying plate 421. Because the bottom of the conical plate 412 is in a semicircular shape, the sludge will be extruded with a greater force, thereby increasing the conveying pressure of the conveying plate 421, so that the extruded sludge can be extruded with lower moisture content. Because the resistance generated by the conical plate 412 makes the filter leaf 432 play a greater filtering effect.

[0090] It is worth noting that after the sludge is preliminarily filtered by the ceramic filter piece 445, the continuously rotating pushing leaf 425 will continue to push the sludge filtered by the ceramic filter piece 445 upwards. When the sludge passes through the filter leaf 432, the filter leaf 432 is in a wavy shape and is placed at an inclination, which generates a greater resistance to further filter the moisture in the sludge. Moreover, the upper part of the filter pressing cylinder 25 is provided with the conical plate 412, so that the movement of the sludge generates a greater resistance, which increases the pressure filtration effect of the sludge between the filter leaf 432 and the conical plate 412. Because the pressure-filtered sludge is extruded, the sludge pressure filtration system can continuously pressure filter the sludge.

[0091] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
