DETAILED DESCRIPTION

[0045] Please refer toFigures 1 to 6 The utility model provides a sludge efficient dewatering device, in order to better understand above -mentioned technical scheme, below will combine with the detailed description of the drawings and specific implementation mode to above -mentioned technical scheme carries out detailed explanation.

[0046] In one embodiment of the technical scheme of the utility model:

[0047] Including sludge frame 1, bottom sealing plate 2, portal frame 3, bearing table 4 and frame push rod 5;

[0048] Bearing table 4 is the flat plate of stable support, and the water filter groove 41 is arranged around the periphery of the bearing table 4;The bearing table 4 is uniformly provided with a plurality of supporting legs 44 at the bottom, and the bearing table 4 is stably erected on the ground through the plurality of supporting legs 44;The portal frame 3 and the bearing table 4 can be an integral structure and are erected on the same reference surface together.

[0049] The edge of the water filter groove 41 is lower than the top height position of the bearing table 4, and the inner edge of the water filter groove 41 and the outer edge of the bearing table 4 are sealingly welded as an integral structure;The water filter groove 41 is connected with the external sewage pipe through the drain port 42 on the outer side wall of the water filter groove 41;The drain port 42 can also be connected with the external sewage treatment tank, so that the sewage can be directly discharged for subsequent treatment after being filtered out, and the sewage accumulation is avoided.

[0050] The frame guide rail 11 and the baffle guide rail 12 are above the water filter groove 41, and the frame guide rail 11, the baffle guide rail 12 and the water filter groove 41 do not contact each other, so that the sludge frame 1 can slide backward without colliding with the water filter groove 41, and the squeezed sewage can flow into the water filter groove 41, so that the water filter groove 41 can collect the sewage flowing out of the sludge frame 1 from the periphery of the bearing table 4.

[0051] The frame guide rail 11 and the baffle guide rail 12 are arranged on the top of the bearing table 4, and the frame guide rail 11 and the baffle guide rail 12 are arranged horizontally along the front and rear directions, and the frame guide rail 11 and the baffle guide rail 12 extend to the rear end of the bearing table 4.

[0052] The rear side of the bearing table 4 is also provided with a sludge tank 22, which is an open-top box with a closed periphery. The sludge tank 22 is located directly below the rear end of the frame guide rail 11 and the baffle guide rail 12. The bottom of the sludge tank 22 is provided with a roller, and the sludge tank 22 is stably placed directly below the frame guide rail 11 and the baffle guide rail 12. The rear end of the sludge frame 1 is located within the receiving range of the sludge tank 22, which facilitates the collection of sludge falling from the sludge frame 1 and the transportation of dewatered sludge. Multiple sludge tanks 22 can be replaced, one full and one empty, to carry the next batch of dewatered sludge, facilitating subsequent fermentation or aggregate addition operations, and ensuring that sludge transportation and dewatering do not interfere with each other, resulting in higher construction efficiency.

[0053] The bottom sealing plate 2 is a flat plate that slides along the front-rear direction on the baffle guide rail 12 on the top of the bearing table 4. The front end of the bottom sealing plate 2 is provided with a bottom plate push rod 21, which is a drive push rod for the bottom sealing plate 2.

[0054] The sludge frame 1 is a square mesh frame with an open top. The periphery and bottom of the sludge frame 1 are both mesh plates. The front end of the sludge frame 1 is connected to a frame push rod 5, which slides horizontally along the front-rear direction on the frame guide rail 11 on the top of the bearing table 4.

[0055] The frame push rod 5 and the bottom plate push rod 21 are both hydraulic rods. The front ends of the frame push rod 5 and the bottom plate push rod 21 are fixedly connected to a vertical reference surface. The fixed reference surface of the frame push rod 5 and the bottom plate push rod 21 can be a wall or a steel positioning seat fixed to the gantry 3.

[0056] The frame push rod 5 and the bottom plate push rod 21 are both horizontally arranged along the front-rear direction. The extension directions of the frame push rod 5 and the bottom plate push rod 21 are the same and parallel to each other.

[0057] The top of the bottom sealing plate 2 is covered with filter cloth, and the periphery of the sludge frame 1 is also covered with filter cloth. The bottom of the sludge frame 1 is not covered with filter cloth, which facilitates the discharge of dewatered sludge and ensures smooth drainage. The mesh size of the bottom of the sludge frame 1 needs to be slightly larger, typically around 10-30 mm, to ensure that the dewatered sludge can easily flow out without affecting the optimal dewatering. The filter cloth prevents fine sludge from flowing away, ensuring that only the moisture in the sludge is released, and the sludge remains in the sludge frame 1. Even if it falls onto the bottom sealing plate 2, the sludge will not fall downward. The bottom sealing plate 2 blocks the sludge frame 1 from falling downward, preventing sludge with a large amount of water from falling into the sludge tank 22. The bottom sealing plate 2 collects the sludge and water together and then sends them to the bearing table 4 for dewatering.

[0058] Therefore the bottom of the sludge tank 2 can also be a pool, when filling the sludge tank 1 with sludge, to avoid sewage falling into the sludge tank 22, the sludge tank 22 can be pulled out first, when the sludge tank 1 is pulled back to the carrying table 4 by the frame push rod 5, the sludge tank 22 is pushed into the position below the baffle guide rail 12, that is, directly below the outer end station of the sludge tank 1, which is convenient for subsequent collection of dewatered sludge.

[0059] The gap between the sludge tank 1 and the bottom sealing plate 2 is not more than 2mm;

[0060] The bottom sealing plate 2 is a stainless steel plate, and the sludge tank 1 is a stainless steel mesh frame;

[0061] The sludge tank 1 is provided with notches on the sidewalls at the front and rear ends; when the bottom sealing plate 2 is at the bottom of the sludge tank 1, the bottom sealing plate 2 is fitted into the notches at the front and rear ends of the sludge tank 1, and the bottom sealing plate 2 and the sludge tank 1 are combined into a complete tank;

[0062] The vertical outer sidewall of the sludge tank 1 is also uniformly provided with a plurality of reinforcing ribs 13, which are vertical angle steels. The reinforcing ribs 13 improve the carrying strength of the sludge tank 1, so that the sludge tank 1 can be more stable during loading and translation, and provide more powerful support.

[0063] The front end station of the sludge tank 1 and the bottom sealing plate 2 is directly above the carrying table 4, and the rear end station of the sludge tank 1 and the bottom sealing plate 2 is directly above the sludge tank 22;

[0064] The top of the bottom sealing plate 2 can be separated and fitted to block the bottom of the sludge tank 1;

[0065] The sludge tank 1 and the bottom sealing plate 2 can be independently controlled and slid on the top of the carrying table 4;

[0066] The gantry 3 is stably erected above the carrying table 4, and the hydraulic machine 31 is arranged on the gantry 3, and the controller 33 is also arranged on the hydraulic machine 31, and the hydraulic machine 31 is electrically connected with the controller 33, and the controller can be a plc controller.

[0067] The lower end of the hydraulic rod of the hydraulic machine 31 is provided with a sludge pressing plate 32, and the sludge pressing plate 32 is controlled by the hydraulic machine 31 to press the sludge downward.

[0068] The sludge pressing plate 32 is arranged directly below the gantry 3, and the sludge pressing plate 32 is horizontally arranged above the carrying table 4 and can be lifted and lowered by the hydraulic machine 31;

[0069] The pressing plate 32 can be lifted to separate the cover and press the sludge in the sludge frame 1, the pressing plate 32 is the same as the sludge frame 1 in the frame shape, and the pressing plate 32 is matched with the sludge frame 1 with a gap, and the gap is not more than 10 mm, so that the pressing plate 32 can conveniently extrude and dewater the sludge in the sludge frame 1, and the gap is too large, and the sludge overflows from the gap, and the gap width is within 5 mm on each side, so that sufficient extrusion force can be generated on the sludge in the sludge frame 1, and the pressing plate 32 can smoothly enter the sludge frame 1 to apply force.

[0070] The existing sludge dewatering machine needs to perform a screening process before sludge dewatering;

[0071] 1, the centrifuge dewatering machine is not suitable for sludge with large blocks, and the dewatering speed is slow, so it is necessary to remove large particles or sludge with large lumps, and the energy consumption is high, the high speed leads to large noise, and the sludge is easy to deviate when rotating at high speed, which leads to frequent vibration of the centrifuge and needs to be adjusted in time;

[0072] 2, the filter belt type dewatering extrusion force is insufficient, the backflow sludge is much, the backwashing water consumption is large, and the adaptability to mixed sludge and biochemical sludge is poor;

[0073] 3, the ring type sludge dewatering machine, if the sludge dewatering machine is not properly maintained, it is easy to appear the situation of blockage or pollution, thereby affecting the dewatering effect and the service life of the equipment, and it is not necessary to select, and the price is relatively high;

[0074] 4, the plate and frame type sludge dewatering machine, sludge dewatering is difficult to clean, and a high-pressure pump is needed to enter the slurry, which is only suitable for sludge with high water content, and the sludge particles need to be small, the limitation conditions are too many, and the operation is very complex, the space occupation is large, and the dewatering efficiency is low.

[0075] The device avoids all the shortcomings of the above-mentioned existing equipment, does not limit the sludge quality, and can operate on bagged or liquid sludge. Even if the mixed sludge has many impurities, even if the bagged and liquid sludge is mixed, the dewatering operation can be performed, and the sludge can be dewatered by pressing. The sludge amount treated at a time is large, as long as the sludge frame 1 can hold, the sludge frame 1 can be processed, generally several tons of sludge can be processed at a time, the processing efficiency is high, and no additional pump or high-pressure conveying device is needed.

[0076] In use, the hydraulic machine 31 drives the pressing plate 32 to rise first, so that the pressing plate 32 is located above the sludge frame 1.

[0077] Then control the frame push rod 5 to extend, and push the sludge frame 1 to the rear position of the bearing table 4, that is, the sludge tank 22 is directly above. Figure 3

[0078] ​The bottom plate push rod 21 also extends and pushes the bottom sealing plate 2 backward, so that the bottom sealing plate 2 remains spliced with the sludge frame 1 and remains in the receiving and sealing state of the bottom sealing plate 2 to the sludge frame 1.

[0079] At this time, the sludge tank 22 is not placed in the rear end station of the sludge frame 1, and then sludge is put into the sludge frame 1, which can be pipeline transportation or vehicle unloading. The raw material put into the sludge frame 1 can be bagged sludge or fluid sludge. As long as it flows out from the sludge frame 1, it is filtered sewage, and the sludge remains in the sludge frame 1.

[0080] Then the bottom plate push rod 21 and the frame push rod 5 are retracted synchronously, the bottom plate push rod 21 and the frame push rod 5 are retracted synchronously, the sludge tank 22 and the sludge frame 1 are pulled back to the top of the supporting table 4, and then the sludge frame 1 and the bottom sealing plate 2 are pulled back to the front end pressurized dewatering station together, that is, the center of the top of the supporting table 4, that is, directly below the mud pressing plate 32.

[0081] Then the controller 33 controls the hydraulic machine 31 to push downward, the mud pressing plate 32 extends downward and presses into the sludge frame 1, and the downward pressing continues until the hydraulic machine 31 applies a certain force, which can be set according to the actual dewatering effect. At the same time of this process, the sludge tank 22 is pushed into the rear end station of the sludge frame 1.

[0082] After the sludge is dewatered, the sewage flows out along the sludge frame 1, and also flows out along the gap between the bottom sealing plate 2 and the bottom of the sludge frame 1, and flows into the surrounding water filter groove 41, and then the drain 42 drains the sewage into the sewage treatment ditch or pipeline.

[0083] When the sludge in the sludge frame 1 is dewatered, the frame push rod 5 and the bottom plate push rod 21 extend backward at the same time, push the sludge frame 1 and the bottom sealing plate 2 backward, the sludge frame 1 slides backward on the frame guide rail 11, the bottom sealing plate 2 slides backward on the baffle guide rail 12, and slides to the rear end station directly above the sludge tank 22, and then the bottom plate push rod 21 retracts again to pull the bottom sealing plate 2 forward. At this time, the weight of the sludge can reach several tons, the extruded and dewatered sludge loses the obstruction of the bottom sealing plate 2, passes through the mesh at the bottom of the sludge frame 1, and falls downward into the sludge tank 22. At this time, the dewatered sludge is obtained, and the sludge dewatering rate can be adjusted according to the control force of the hydraulic machine 31 for convenient use.

[0084] The device does not limit the quality and impurities of sludge dewatering, nor the physical properties of sludge dewatering, and the dewatering effect can meet the requirements for convenient use.

[0085] The front end of the device refers to the left end of the frame push rod 5, that is, the end where the frame push rod 5 is arranged, and the rear end refers to the end of the sludge tank 22 where the sludge is loaded and unloaded, that is, Figure 3 Figure 3 ​The indicated spatial or positional relationship is based on the spatial or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0086] Although the specific embodiments of the utility model are described above, those skilled in the art should understand that the specific examples described by us are only illustrative, and are not used to limit the scope of the utility model, and equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the utility model should be covered within the scope of protection of the claims of the utility model.
