Description

Technical Field

[0001] The present invention relates to the technical field of sludge dewatering, in particular to a sludge dewatering treatment system and a treatment method. Background Art

[0002] Sludge dewatering systems are a key component of the wastewater treatment process. They are used to remove water from sludge, achieving sludge reduction and stabilization. They typically consist of sludge conditioning, sludge conveying, and dewatering equipment. Sludge conditioning involves adding flocculants and other agents to improve sludge dewatering properties, agglomerating sludge particles into larger flocs for easier dewatering. Sludge conveying transports the conditioned sludge to the dewatering equipment. Common conveying methods include pumping and gravity flow. Common dewatering equipment includes belt filter presses, centrifugal dewatering machines, and plate and frame filter presses. Belt filter presses utilize a filter belt to squeeze and dewater sludge, offering simple operation and low operating costs. Centrifugal dewatering machines rely on centrifugal force to remove water from sludge, resulting in effective dewatering and a high degree of automation. Plate and frame filter presses apply pressure to the sludge through the filter plates, forcing water out through the gaps between the filter plates, resulting in a sludge cake with a low moisture content.

[0003] The plate and frame assembly used in traditional plate and frame filter presses is a closed plate frame, which is prone to mesh clogging. Once the mesh of the plate and frame assembly is clogged, it requires a long period of shutdown for cleaning. Although some backwashing structures have been designed to address the clogging of the plate and frame mesh, making the cleaning process simpler, it requires a large amount of clean water. Therefore, improving the plate and frame assembly is one of the important issues currently facing sludge dewatering treatment. Summary of the Invention

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0049] like Figure 1 - Figure 8 As shown, an embodiment of the present invention provides a sludge dewatering treatment system, including a support system, a frame structure 4, an extrusion system 6, a plate and frame assembly 8, an elastic pad 9 and a cover plate (not shown in the figure).

[0050] The support system forms a lower trough, and the frame structure 4 is fixedly installed on the top of the support system, and the frame structure 4 has an upper trough corresponding to the lower trough. The support system is used to lift the frame structure 4, and the sewage, mud cakes, etc. falling from the upper trough can all fall into the lower trough, so as to facilitate separate transportation. For example, a conveying system is installed in the lower trough, which can transport the falling mud cakes when working, while the sewage produced by squeezing cannot be transported out by the conveying system, wherein one end of the upper trough is blocked, and the other end is provided with an extrusion system 6, and a plate-frame assembly 8 is arranged on the inner side of the upper trough. There are multiple plate-frame assemblies 8, and the multiple plate-frame assemblies 8 are distributed in parallel in the same direction (the same direction here means that the bottom plate 802 extends in one direction), and the plate-frame assembly 8 is arranged on the inner side of the frame structure 4. The plate-frame assembly 8 includes a plate-frame member 801, a bottom plate member 802, and a bottom plate member 802. One end is rotatably mounted on the plate frame member 801 near the bottom end. The plate frame member 801 and the bottom plate member 802 are both porous structures. During the sludge squeezing process, sewage overflows from the porous structure. The elastic pad 9 is set on the bottom cross frame 401, and the elastic pad 9 is used to elastically support the end of the bottom plate member 802 away from the plate frame member 801. The cover plate corresponds to the top of the frame structure 4.

[0051] When in use, multiple plate-frame assemblies 8 are arranged in the same direction on the inner side of the frame structure 4. Since the elastic pad 9 supports the bottom plate 802, the bottom plate 802 is approximately horizontal (the angle between the plate-frame 801 and the bottom plate 802 is slightly greater than 90 degrees). When multiple plate-frame assemblies 8 are distributed in the same direction and in parallel, two adjacent plate-frame assemblies 801, the bottom plate 802 and the two sides of the frame structure 4 form a mud storage tank with an open top. Then, sludge is filled into the mud storage tank (for example, by using a pumping system for pumping). Then, the top of the frame structure 4 is covered with a cover plate. Then, the squeezing system 6 pushes the multiple plate-frame assemblies 8 together, that is, pushes a plate-frame assembly 8 close to the squeezing system 6, and the remaining plate-frame assemblies 8 transmit thrust in turn, so that the multiple plate-frame assemblies 8 are close to each other, and the bottom end of the plate-frame 801 of the plate-frame assembly 8 on the front side squeezes the bottom plate 802 of the plate-frame assembly 8 on the rear side, so that the bottom plate 802 The bottom end of the plate 802 is rotated downward, so that the angle between the bottom plate 802 and the horizontal plane increases, and the plate frame members 801 of two adjacent plate frame assemblies 8 are close to each other, so that the space of the mud storage tank is compressed, thereby achieving sludge squeezing and dehydration.

[0052] The present invention designs an L-shaped plate-frame assembly 8 composed of plate-frame members 801 and bottom plate members 802, and an elastic pad 9 supports the bottom plate member 802 so that the bottom plate member 802 is approximately horizontal. It relies on multiple plate-frame assemblies 8 to be arranged in the same direction on the inner side of the frame structure 4, so that two adjacent plate-frame members 801, bottom plate members 802 and both sides of the frame structure 4 form a mud storage tank with an open top. A cover plate is used to cover the top of the frame structure 4, and then the extrusion system is driven to bring the plate-frame members 801 of the two adjacent plate-frame assemblies 8 close to each other, so that the space in the mud storage tank is compressed, thereby achieving sludge extrusion and dehydration. In this method, the structure of the plate-frame assembly 8 is simple, and the porous structure plate structure is open to the outside. The user can directly use an air gun to blow the plate-frame members 801 and bottom plate member 802 to clean the solid matter remaining in the porous structure. Compared with the traditional plate-frame assembly cleaning that requires a large amount of clean water, the use and cleaning process of this solution are simpler and save water.

[0053] In one embodiment, the frame structure 4 includes: a bottom cross frame 401 , a side frame assembly 402 , a second cross frame 403 , and a water retaining plate 404 .

[0054] There are multiple bottom cross frames 401, and the multiple bottom cross frames 401 are all fixed on the top of the support system, and the bottom cross frames 401 are perpendicular to the lower trough. The multiple bottom cross frames 401 are flattened to form a hollow support surface. The side frame assembly 402 is fixedly installed on the top of the bottom cross frame 401. There are two groups of side frame assemblies 402 symmetrically arranged, and an upper trough is formed between the two groups of side frame assemblies 402. The second cross frame 403 is fixedly connected between the two groups of side frame assemblies 402, and the second cross frame 403 is located at one end of the upper trough, that is, the second cross frame 403 is used to block one end of the upper trough. The water baffle 404 is fixedly installed with the side frame assembly 402, and the water baffle 404 is located on the outside of the second cross frame 403. The water baffle 404 is used to protect the power box 505 part on the conveying system 5 to prevent sewage from being sprayed toward the power box 505 during the dehydration process.

[0055] The frame structure 4 is integrally formed by welding and assembling steel plates and steel frame structures. The overall structure is used to install and restrict the plate-frame assembly 8 and cooperates with the plate-frame assembly 8, the extrusion system 6 and other structures to achieve extrusion dehydration.

[0056] In one embodiment, the side frame assembly 402 includes a supporting base plate 402a, a side plate 402b, a first diagonal brace 402c, and a second diagonal brace 402d.

[0057] Among them, the supporting bottom plate 402a is fixedly connected to multiple bottom cross frames 401, the bottom of the side plate 402b is fixedly connected to the side of the supporting bottom plate 402a, and a first diagonal brace 402c and a second diagonal brace 402d are fixedly connected between the side plate 402b and the supporting bottom plate 402a. The second diagonal brace 402d is located at the end of the side plate 402b. The supporting bottom plate 402a, the side plate 402b and the first diagonal brace 402c or the second diagonal brace 402d form a triangular structure, which is used to ensure the stability of the lateral support of the side plate 402b and prevent the side plate 402b from being deformed or invaded by force during use. A water outlet 402d1 is opened on the side of the second diagonal brace 402d. The water outlet 402d1 guides out sewage that may remain on the supporting bottom plate 402a. The side plate 402b is a porous mesh plate.

[0058] In one embodiment, the plate frame 801 is a hollow structure, and sewage can overflow from both sides and enter the inner side of the plate frame 801. The bottom end of the plate frame 801 is open, and a rectangular opening 801a is provided on the top of the plate frame 801. The rectangular opening 801a corresponds to the lifting tool 709. The bottom of the plate frame 801 is provided with a mounting notch 801b. The side of the bottom plate 802 is provided with a side opening 802a. One end of the side opening 802a is flush with the bottom plate 802, and the other end of the side opening 802a forms a protrusion on the side of the bottom plate 802. One end of the bottom plate 802 is rotatably mounted inside the mounting notch 801b via a shaft. Figure 6 As shown in FIG, the side opening 802a forms a protrusion on the side of the bottom plate 802, and the protrusion is used to limit the distance between the next plate frame assembly 8 and the current plate frame assembly 8. Specifically, the bottom of the plate frame member 801 can be inserted into the side opening 802a.

[0059] In one embodiment, the extrusion system 6 includes: a bracket 601 , a main hydraulic cylinder 603 , a guide telescopic member 602 , and a push plate 604 .

[0060] The bracket platform 601 is fixedly installed on the bottom cross frame 401. The bracket platform 601 is a concrete and steel structure component, which plays a stable supporting role. The telescopic end of the main hydraulic cylinder 603 is fixedly installed with a push plate 604 on the inner side of the upper groove. The guide telescopic member 602 is fixedly connected to the outer side of the main hydraulic cylinder 603, and the telescopic end of the guide telescopic member 602 is fixedly installed with the push plate 604. The guide telescopic member 602 is used to guide the push plate 604. The side of the plate frame member 801 of a plate frame assembly 8 close to the push plate 604 is fixedly connected with a protruding plate 803. The side of the push plate 604 is fixedly connected with two parallel limiting blocks 605, and the protruding plate 803 corresponds to the middle area of ​​the two limiting blocks 605.

[0061] During use, the main hydraulic cylinder 603 drives the push plate 604 to move, which in turn causes the slide rod portion of the guide telescopic member 602 to extend. The guide telescopic member 602 ensures the smooth movement of the push plate 604. The push plate 604 moves toward the plate-frame assembly 8, causing the protruding plate 803 to be inserted between the two limiting blocks 605. While pushing the plate-frame assembly 8, the structure of the protruding plate 803 inserted between the two limiting blocks 605 limits the upward and downward movement of the plate-frame assembly 8.

[0062] In one embodiment, the invention further comprises: a lifting frame assembly 7 , which is used when removing the mud cake and is used to lift the frame assembly 8 .

[0063] As analyzed above, the plate-frame members 801 of two adjacent plate-frame assemblies 8 are brought close together, thereby compressing the space in the mud storage tank, thereby achieving sludge squeezing and dehydration. After dehydration is completed, the squeezing system 6 releases the squeezing force, and the mud block is located above the bottom plate 802 and attached to the side of the plate-frame member 801. The user can use the lifting frame assembly 7 to lift the corresponding plate-frame assembly 8 to remove the mud cake on the plate-frame assembly 8.

[0064] Specifically, the lifting frame assembly 7 includes: a cantilever bracket 701 , a guide rod 702 , a screw rod 703 , a sliding block 705 , a motor 704 , a hydraulic telescopic member 706 , a suspension chain 708 and a lifting tool 709 .

[0065] The cantilever bracket 701 is fixedly installed on the support system. The cantilever bracket 701 is in a "7" shape. The cantilever bracket 701 is provided with two groups. The two groups of cantilever brackets 701 are rotatably installed with screw rods 703 and fixedly installed with guide rods 702. One end of the cantilever bracket 701 is fixedly installed with a motor 704. One end of the motor 704 is transmission-connected to the screw rod 703. The motor 704 is used to drive the screw rod 703 to rotate. The sliding block 705 is threadedly matched with the screw rod 703. The sliding block 705 is slidingly matched with the guide rod 702. When in use, the guide rod 702 guides the moving direction of the sliding block 705, and the rotating screw rod 703 drives the sliding block 705 to move linearly. The top of the hydraulic telescopic member 706 is fixedly installed with the sliding block 705. The bottom telescopic end of the hydraulic telescopic member 706 is fixedly installed with a stabilizing frame 707. The lifting tooling 709 is connected to the lifting tooling 709 by at least two sets of suspension chains 708. For fixed installation with Stabilizer 707.

[0066] During use, the user drives the screw rod 703 to rotate through the motor 704, and the screw rod 703 cooperates with the sliding block 705 to drive the sliding block 705 to slide along the guide rod 702, so that the lifting tooling 709 moves to the position of the plate frame assembly 8 that needs to be lifted. The hydraulic telescopic part 706 controls the lifting tooling 709 to move downward, and the lifting tooling 709 is connected to the upper plate frame assembly 8. The hydraulic telescopic part 706 retracts, lifting the plate frame assembly 8 upward, and then puts it back to its original position.

[0067] In one embodiment, the lifting tool 709 includes a plate 709a, a telescopic block 709d, a connecting seat 709g, a connecting rod 709j, an elastic support rod 709k and a central column 709e.

[0068] The top of both sides of the plate body 709a is provided with a limiting portion 709b, and the bottom of the plate body 709a can be inserted into the rectangular opening 801a. The limiting portion 709b limits the plate body 709a from being fully inserted into the rectangular opening 801a. The side of the plate body 709a is provided with a transverse sliding opening 709c, and the top of the plate body 709a is provided with a triangular cavity 709f connected to the transverse sliding opening 709c. The telescopic block 709d is slidably arranged on the inner side of the transverse sliding opening 709c. The telescopic block 709d can slide laterally. There are two groups of telescopic blocks 709d, and the two groups of telescopic blocks 709d are symmetrically distributed on both sides of the plate body 709a. An elastic support rod 709k is provided between the two groups of telescopic blocks 709d. Under the action of the elastic support rod 709k, the two groups of telescopic blocks 709d extend to both sides respectively, and the telescopic blocks 709d extend out of the transverse sliding opening 709c. One end of the plate 709a is provided with a downward oblique opening 709d1. When the bottom of the plate 709a is inserted into the rectangular opening 801a, the side of the rectangular opening 801a squeezes the oblique opening 709d1, which can cause the two sets of telescopic blocks 709d to retract inward, so that the two sets of telescopic blocks 709d pass over the rectangular opening 801a. The connecting seat 709g is located at the top opening of the triangular cavity 709f. The connecting seat 709g is connected to the stabilizing frame 707 through the operating rope 709h. The operating rope 709h is provided with a metal ring 709i. The connecting rod 709j is located on the inner side of the triangular cavity 709f, and one end of the connecting rod 709j is movably connected to the telescopic block 709d, and the other end of the connecting rod 709j is movably connected to the connecting seat 709g. A central column 709e is installed in the center of the triangular cavity 709f. The operating rope 709h is generally slightly longer than the suspension chain 708. The operating rope 709h does not transmit the upward lifting force of the hydraulic telescopic member 706. When in use, since the lifting tooling 709 is in a suspended state, the user can manually adjust the position of the lifting tooling 709, and lower the lifting tooling 709 by the hydraulic telescopic member 706. The bottom of the lifting tooling 709 is operated to be inserted into the rectangular opening 801a. When the bottom of the plate body 709a continues to be inserted into the rectangular opening 801a, the side of the rectangular opening 801a squeezes the oblique opening 709d1, which can cause the two groups of telescopic blocks 709d to retract inward, so that the two groups of telescopic blocks 709d pass over the rectangular opening 801a. The user can operate the hydraulic telescopic member 706 to retract upward, drive the lifting tooling 709 to move upward, and then drive the plate and frame assembly 8 to move upward. In one embodiment, it also includes: a conveying system 5, which is arranged on the inner side of the lower trough. The conveying system 5 is used to convey the mud blocks to one side (the discharge end of the conveying system 5).

[0069] The conveying system 5 includes: a first roller 501 rotatably installed on the inner side of the lower trough, a power roller 503 rotatably installed at one end of the support system, and a second roller 502 swingably installed at one end of the support system through a connecting rod bracket 504. The connecting rod bracket 504 can swing elastically in a small range, so that the conveyor belt has a certain elasticity to prevent the falling mud blocks from impacting the conveyor belt and causing damage to the conveyor belt. A conveyor belt is installed between the first roller 501, the second roller 502 and the power roller 503. A power box 505 is fixedly installed on the side of the support system. The output end of the power box 505 is connected to the power roller 503 by transmission. The power box 505 drives the power roller 503 to rotate, and the power roller 503 drives the conveyor belt, thereby causing the first roller 501 and the second roller 502 to rotate as well.

[0070] In one embodiment, the support system includes a foundation pile 1 and a beam frame 2 fixed on the top of the foundation pile 1. The foundation pile 1 and the beam frame 2 are both concrete structures, which can be built in a sludge pool. The concrete structure has a certain corrosion resistance, and the service life of the overall structure is longer.

[0071] The pumping system 3 is installed on the side of the beam 2. The pumping system 3 has a feed pipe 3a and a discharge pipe 3b. When the pumping system 3 is working, it is used to pump the sludge in the sludge pool into the sludge storage tank. Example 2:

[0072] A sludge dewatering treatment method, using the sludge dewatering treatment system of Example 1, specifically comprises the following steps:

[0073] S1. Arrange multiple plate-frame assemblies 8 in the same direction on the inner side of the upper channel, forming a mud storage trough with an open top between two adjacent plate-frame assemblies 8, and support the bottom end of the bottom plate 802 with an elastic pad 9, so that the bottom plate 802 is approximately in a tilted state at a small angle.

[0074] S2. Fill the sludge storage tank with sludge, and then use a cover plate to cover the top of the frame structure 4, so that the sludge storage tank forms an area closed to the sludge (the side walls of the area are porous, and the sewage can overflow) to prevent the sludge from being squeezed out.

[0075] S3. The squeezing system 6 pushes the multiple plate and frame assemblies 8 together, and the plate and frame members 801 of the adjacent plate and frame assemblies 8 slide. The bottom ends of the plate and frame members 801 squeeze the bottom plate member 802, and the bottom end of the bottom plate member 802 rotates downward, so that the angle between the bottom plate member 802 and the horizontal plane increases, and the space in the mud storage tank is compressed, thereby achieving sludge squeezing and dehydration.

[0076] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
