Description

Technical Field

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

[0002] The sludge dewatering treatment system is a key link in the sewage treatment process. It is used to remove moisture from the sludge and achieve sludge reduction and stabilization. It is usually composed of sludge conditioning, sludge transportation, dewatering equipment and other parts. Sludge conditioning is to improve the dewatering performance of sludge by adding flocculants and other agents, so that the particles in the sludge are condensed into larger flocs for subsequent dewatering. Sludge transportation is to transport the conditioned sludge to the dewatering equipment. Common transportation methods include pumping and gravity flow transportation. Common dewatering equipment includes belt filter press, centrifugal dewatering machine and plate and frame filter press. Belt filter press uses filter belt to squeeze and dewater sludge, which is simple to operate and has low operating cost. Centrifugal dewatering machine relies on centrifugal force to throw out the water in the sludge, with good dewatering effect and high degree of automation. Plate and frame filter press applies pressure to the sludge through the plate frame to discharge water from the gap of the filter plate, and obtains mud cake with 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 are designed to solve the problem of plate and frame mesh clogging, making the cleaning process simple, it consumes 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

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0045] Embodiment 1:

[0046] 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).

[0047] The support system forms a lower trough, 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 transportation system is installed in the lower trough, which can transport the fallen mud cakes when working, while the sewage produced by squeezing cannot be transported out by the transportation 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, and the plate frame assembly 8 is provided with a plurality of The components 8 are distributed in parallel in the same direction (the same direction here means that the bottom plate 802 extends in one direction), the plate and frame components 8 are arranged on the inner side of the frame structure 4, and the plate and frame components 8 include a plate and frame component 801 and a bottom plate component 802. One end of the bottom plate component 802 is rotatably installed at a position close to the bottom end of the plate and frame component 801. Both the plate and frame component 801 and the bottom plate component 802 are porous structures. During the sludge extrusion process, sewage overflows from the porous structure. The elastic pad 9 is arranged on the bottom cross frame 401, and the elastic pad 9 is used to elastically support one end of the bottom plate component 802 away from the plate and frame component 801, and the cover plate corresponds to the top of the frame structure 4.

[0048] When in use, multiple plate-frame components 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 component 801 and the bottom plate 802 is slightly greater than 90°). When multiple plate-frame components 8 are distributed in parallel in the same direction, two adjacent plate-frame components 801, the bottom plate 802 and the two sides of the frame structure 4 form a mud storage tank with an open top, and then fill the mud storage tank with sludge (for example, use a pumping system to pump it), and then use a cover plate to cover the top of the frame structure 4. Cover, then the extrusion system 6 pushes multiple plate and frame assemblies 8 together, that is, pushes a plate and frame assembly 8 close to the extrusion system 6, and the remaining plate and frame assemblies 8 transmit thrust in turn, so that multiple plate and frame assemblies 8 are close to each other, and the bottom end of the plate and frame component 801 of the plate and frame assembly 8 located on the front side squeezes the bottom plate component 802 of the plate and frame assembly 8 located on the rear side, so that the bottom end of the bottom plate component 802 rotates downward, so that the angle between the bottom plate component 802 and the horizontal plane increases, and the plate and frame components 801 of two adjacent plate and frame assemblies 8 are close to each other, so that the space of the mud storage tank is compressed, thereby realizing the extrusion and dehydration of the sludge.

[0049] The present invention designs an L-shaped plate-frame assembly 8 composed of a plate-frame member 801 and a bottom plate member 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, the bottom plate member 802 and the two sides of the frame structure 4 form a mud storage tank with an open top. The top of the frame structure 4 is covered with a cover plate, 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 of the mud storage tank is compressed, thereby realizing the extrusion and dehydration of the sludge. In this method, the structure of the plate-frame assembly 8 is simple, and the porous plate structure is open to the outside. The user can directly use an air gun to blow the plate-frame member 801 and the bottom plate member 802 to clean the solid matter remaining in the porous structure. Compared with the traditional plate-frame assembly cleaning which requires a large amount of clean water, the use and cleaning process of this solution are simpler and save water.

[0050] 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 .

[0051] There are multiple bottom cross frames 401, which are all fixed on the top of the support system, and the bottom cross frames 401 are perpendicular to the lower channel. The multiple bottom cross frames 401 are laid flat to form a hollow support surface. The side frame assembly 402 is fixedly installed on the top of the bottom cross frame 401. The side frame assembly 402 is symmetrically arranged in two groups, and an upper channel 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 lower channel, that is, the second cross frame 403 is used to block one end of the upper channel. The water retaining plate 404 is fixedly installed with the side frame assembly 402, and the water retaining plate 404 is located on the outside of the second cross frame 403. The water retaining plate 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.

[0052] 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 realize extrusion dehydration.

[0053] In one embodiment, the side frame assembly 402 includes: a supporting bottom plate 402a, a side plate 402b, a first diagonal brace 402c, and a second diagonal brace 402d.

[0054] 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 the first diagonal brace 402c and the second diagonal brace 402d are fixedly connected between the side plate 402b and the supporting bottom plate 402a, and 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, and the water outlet 402d1 guides out the sewage that may remain on the supporting bottom plate 402a. The side plate 402b is a porous mesh plate.

[0055] In one embodiment, the plate frame 801 is a hollow structure, and sewage can overflow from both sides to enter the inner side of the plate frame 801. The bottom end of the plate frame 801 is an opening, and a rectangular opening 801a is provided on the top of the plate frame 801, and the rectangular opening 801a corresponds to the lifting tool 709. A mounting notch 801b is provided at the bottom of the plate frame 801, and a side opening 802a is provided on the side of the bottom plate 802. One end of the side opening 802a is flush with the bottom plate 802, and the other end of the side opening 802a is formed on the side of the bottom plate 802 to form a protrusion. One end of the bottom plate 802 is rotatably installed in the mounting notch 801b through a shaft, as shown in FIG. Figure 6 As shown in , the side opening 802a forms a protrusion on the side of the bottom plate member 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 position of the side opening 802a.

[0056] In one embodiment, the extrusion system 6 includes: a bracket 601 , a main hydraulic cylinder 603 , a guiding telescopic member 602 and a push plate 604 .

[0057] 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 role of stable support. 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. A protruding plate 803 is fixedly connected to the side of a plate frame member 801 of a plate frame assembly 8 close to the push plate 604. Two parallel limiting blocks 605 are fixedly connected to the side of the push plate 604, and the protruding plate 803 corresponds to the middle area of ​​the two limiting blocks 605.

[0058] When in use, the main hydraulic cylinder 603 drives the push plate 604 to move, and the push plate 604 drives the sliding rod part of the guiding telescopic member 602 to extend, relying on the guiding telescopic member 602 to ensure the smooth movement of the push plate 604, and the push plate 604 moves toward the plate frame assembly 8, so that the protruding plate 803 is stuck between the two limiting blocks 605. While pushing the plate frame assembly 8, the structure of the protruding plate 803 stuck between the two limiting blocks 605 limits the movement of the plate frame assembly 8 in the up and down directions.

[0059] In one embodiment, it further comprises: a lifting frame assembly 7 , which is used when removing the mud cake and is used to lift the frame assembly 8 .

[0060] As analyzed above, the plate-frame components 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 realizing the squeezing and dehydration of the sludge. After the dehydration is completed, the squeezing system 6 removes the squeezing force, and the mud block is located above the bottom plate component 802 and attached to the side of the plate-frame component 801. The user can use the lifting frame assembly 7 to lift the corresponding plate-frame assembly 8 to make the mud cake on the plate-frame assembly 8 fall off.

[0061] 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 .

[0062] The cantilever bracket 701 is fixedly installed on the support system, and the cantilever bracket 701 is in a "7"-shaped structure. 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, and one end of the motor 704 is transmission-connected with the screw rod 703. The motor 704 is used to drive the screw rod 703 to rotate, and 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, and the bottom telescopic end of the hydraulic telescopic member 706 is fixedly installed with a stabilizing frame 707. The lifting tooling 709 is fixedly installed with the stabilizing frame 707 through at least two groups of suspension chains 708.

[0063] When in 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, and 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, and the hydraulic telescopic part 706 retracts to lift the plate frame assembly 8 upward, and then put it back to its original position.

[0064] In one embodiment, the lifting tool 709 includes: a plate body 709a, a telescopic block 709d, a connecting seat 709g, a connecting rod 709j, an elastic support rod 709k and a central column 709e.

[0065] The top of both sides of the plate body 709a is provided with a limiting portion 709b, the bottom of the plate body 709a can be inserted into the rectangular opening 801a, and the limiting portion 709b limits the plate body 709a to be completely 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, and the telescopic block 709d can slide transversely. The telescopic block 709d is provided with two groups, and the two groups of telescopic blocks 709d are symmetrically distributed at On both sides of the plate body 709a, an elastic support rod 709k is arranged between the two groups of telescopic blocks 709d.

One end of the telescopic block 709d extending out of the horizontal sliding opening 709c is provided with a downward inclined opening 709d1. When the bottom of the plate body 709a is inserted into the rectangular opening 801a, the side of the rectangular opening 801a squeezes the inclined opening 709d1, so that the two groups of telescopic blocks 709d can be retracted inwardly, so that the two groups of telescopic blocks 709d pass over the rectangular opening 801a, and the connecting seat 709g is located at the top 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 inside 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, due to the lifting tool 7 09 is in a suspended state, and the user can manually adjust the position of the lifting tool 709, and lower the lifting tool 709 by the hydraulic telescopic member 706, and operate the bottom of the lifting tool 709 to insert it 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 make the two sets of telescopic blocks 709d retract inward, so that the two sets of telescopic blocks 709d pass over the rectangular opening 801a, and the user can operate the hydraulic telescopic member 706 to retract upward, drive the lifting tool 709 to move upward, and then drive the plate frame assembly 8 to move upward.
