Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, in particular to a sludge high-efficiency dehydration device. Background Art

[0002] Sludge treatment refers to the process of reducing, stabilizing and harmless processing of collected sludge by concentration, conditioning, dehydration, stabilization, drying or incineration. The main purpose of sludge treatment is to reduce the volume of sludge, reduce its pollution to the environment, and ensure that the treated sludge will not have adverse effects on the ecological environment.

[0003] Sludge can now be used as organic fertilizer, which can not only effectively reduce pollution but also recycle waste.

[0004] After being collected, the sludge generally has a water content of 80%, and needs to be filtered to remove the water and only take the sludge. The filtered wastewater needs to be treated through other treatment processes.

[0005] The filtered sludge still has a very high water content and needs to be dehydrated before it can be processed in subsequent processes. If the sludge is to be fermented for organic matter, a water content of less than 50% is required; and if the sludge needs to be treated as waste, the lower the better, generally a water content of less than 25% is required before subsequent drying and finally incineration.

[0006] At present, the dewatering equipment of sludge mainly uses sludge drying bed and sludge dewatering machine for dewatering. Sludge drying bed is a natural percolation method to filter water, which has a slow water filtering speed, has more requirements on weather and natural environment, and occupies a large area. There are many types of sludge dewatering machines, including centrifugal, filter belt, spiral ring type and plate and frame type. These types of sludge dewatering machines have their own advantages and disadvantages.

[0007] The sludge raw materials currently used include liquid sludge with very high water content, and sludge in bags with slightly lower water content. The existing sludge dewatering machines can generally only dewater the diluted mixed sludge, but when the sludge is dewatered, the bagged sludge will not scatter and overflow, causing less pollution to the surrounding environment. Therefore, the sludge is now directly dehydrated on the belt, which can also facilitate the subsequent dewatering of the sludge at a uniform speed, and facilitate the transportation to the subsequent sludge and mixing and fermentation treatment.

[0008] Based on this, the present invention designs a sludge high-efficiency dewatering device to solve the above problems. Summary of the invention

[0009] The object of the present invention is to provide a sludge high-efficiency dewatering device, which can cooperate with a sludge frame and a hydraulic press to dewater the bagged sludge and directly press the fluid sludge to complete the filter pressing dewatering. There is no need to repeatedly centrifuge and wait for the sludge to rotate and throw out the water. Instead, the sludge is directly pressed by a sludge pressing plate in cooperation with the sludge frame to keep the sludge in the sludge frame, while the sewage passes through the sludge frame and is discharged into the filter tank. This not only facilitates the dewatering of the sludge, but also completes the operation by pressing once.

DETAILED DESCRIPTION

[0045] See also Figures 1 to 6As shown, the present invention provides a sludge efficient dewatering device. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings in the specification and specific implementation methods.

[0046] In a specific embodiment of the technical solution of the present invention:

[0047] It includes a sludge frame 1, a bottom sealing plate 2, a gantry 3, a bearing platform 4 and a frame push rod 5;

[0048] The bearing platform 4 is a stable supported flat plate, and a water filter trough 41 is arranged around the bearing platform 4; a plurality of supporting feet 44 are evenly arranged at the bottom of the bearing platform 4, and the bearing platform 4 is stably erected on the ground through the plurality of supporting feet 44, and the gantry 3 and the bearing platform 4 can be an integral structure, and are erected together on the same reference plane;

[0049] The edge of the water filter trough 41 is lower than the top height of the supporting platform 4. The inner edge of the water filter trough 41 and the outer edge of the supporting platform 4 are sealed and welded to form an integral structure. A drain outlet 42 is opened on the outer wall of the water filter trough 41. The water filter trough 41 is connected to an external sewage pipe through the drain outlet 42; the drain outlet 42 can also be connected to an external sewage treatment tank, so that the sewage can be directly discharged for subsequent treatment after filtering, avoiding sewage accumulation.

[0050] The frame guide rail 11 and the baffle guide rail 12 are located above the water filter trough 41, and the frame guide rail 11, the baffle guide rail 12 and the water filter trough 41 do not contact each other, avoiding interference when the sludge frame 1 slides, so that the sludge frame 1 and the bottom sealing plate 2 can slide to the rear end conveniently, not only without colliding with the water filter trough 41, but also the squeezed sewage can flow downward into the water filter trough 41, so that the water filter trough 41 can collect the sewage flowing out of the sludge frame 1 from all around the supporting platform 4.

[0051] A frame guide rail 11 and a baffle guide rail 12 are arranged on the top of the carrying platform 4. The frame guide rail 11 and the baffle guide rail 12 are arranged horizontally along the front-back direction. The frame guide rail 11 and the baffle guide rail 12 extend backward to the rear end of the carrying platform 4.

[0052] A sludge box 22 is also provided on the rear side of the supporting platform 4. The sludge box 22 is a box body with an opening on the top and closed on all sides. The sludge box 22 is located directly below the rear ends of the frame guide rails 11 and the baffle guide rails 12; rollers are provided at the bottom of the sludge box 22, and the sludge box 22 is stably placed directly below the frame guide rails 11 and the baffle guide rails 12; the rear end station of the sludge frame 1 is within the receiving range of the sludge box 22, which is convenient for collecting the sludge dropped from the sludge frame 1, and also for transporting the dehydrated sludge. Multiple sludge boxes 22 can be replaced. After one is full, an empty sludge box 22 is replaced to carry the next dehydrated sludge, which is convenient for subsequent fermentation of the sludge or addition of aggregate, so that the transportation and dehydration of the sludge do not affect each other, and the construction efficiency is higher.

[0053] The bottom sealing plate 2 is a flat plate, and is slidably arranged on the baffle guide rail 12 on the top of the bearing platform 4 along the front-back direction. A bottom plate push rod 21 is arranged at the front end of the bottom sealing plate 2, and the bottom plate push rod 21 is a driving push rod of the bottom sealing plate 2.

[0054] The sludge frame 1 is a square mesh frame with an open top, and the surroundings and bottom of the sludge frame 1 are mesh plates; the front end of the sludge frame 1 is connected to a frame push rod 5, and the sludge frame 1 is horizontally slidably arranged on a frame guide rail 11 on the top of the supporting platform 4 along the front-back direction through the frame push rod 5;

[0055] The frame push rod 5 and the base plate push rod 21 are both hydraulic rods. The front ends of the frame push rod 5 and the base plate push rod 21 are fixedly connected to a vertical reference plane. The reference plane to which the frame push rod 5 and the base plate push rod 21 are fixed can be a wall or a steel positioning seat fixed to the gantry 3, so as to facilitate the fixing of the frame push rod 5 and the base plate push rod 21.

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

[0057] The top of the bottom sealing plate 2 is covered with filter cloth, and the mesh plates around the sludge frame 1 are also covered with filter cloth. The bottom of the sludge frame 1 is not covered with filter cloth, which is convenient for the discharge of dehydrated sludge and can also drain water more smoothly. The mesh hole at the bottom of the sludge frame 1 needs to be set slightly larger, generally around 10-30mm, to ensure that the sludge is easy to flow out after dehydration and does not affect the optimal dehydration; the filter cloth is used to prevent fine sludge from flowing away, to ensure that only the water in the sludge overflows, and the mud is kept in the sludge frame 1, even if it falls on the bottom sealing plate 2, it can prevent the sludge from falling downward, and the sludge with a large amount of sewage can be prevented from falling into the sludge box 22. The sludge and water are collected together through the bottom sealing plate 2, and then sent together to the supporting platform 4 for dehydration.

[0058] Therefore, the bottom of the sludge box 2 can also be a pool. When filling the sludge in the sludge frame 1, to prevent sewage from falling into the sludge box 22, the sludge box 22 can be dragged out first. When the sludge frame 1 is pulled back to the supporting platform 4 by the frame push rod 5, the sludge box 22 is pushed under the baffle guide rail 12, that is, directly under the outer end station of the sludge frame 1, to facilitate the subsequent collection of the dehydrated sludge.

[0059] There is a clearance fit between the sludge frame 1 and the bottom sealing plate 2, and the clearance does not exceed 2mm;

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

[0061] Notches are provided on the side walls at the front and rear ends of the sludge frame 1; when the bottom sealing plate 2 is at the bottom of the sludge frame 1, the bottom sealing plate 2 is engaged with the notches at the front and rear ends of the sludge frame 1, and the bottom sealing plate 2 and the sludge frame 1 are combined into a complete box body;

[0062] A plurality of reinforcing ribs 13 are evenly arranged on the vertical outer side wall of the sludge frame 1. The reinforcing ribs 13 are vertically arranged angle steels. The reinforcing ribs 13 are used to improve the bearing strength of the sludge frame 1, so that the sludge frame 1 can be more solid and provide stronger support when loading and translating.

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

[0064] The top of the bottom sealing plate 2 can be detachably fitted and sealed on the bottom of the sludge frame 1;

[0065] The sludge frame 1 and the bottom sealing plate 2 can be independently controlled and slidably arranged on the top of the bearing platform 4;

[0066] The gantry 3 is stably erected just above the bearing platform 4. A hydraulic press 31 is arranged on the gantry 3. A controller 33 is also arranged on the hydraulic press 31. The hydraulic press 31 is electrically connected to the controller 33. The controller may be a PLC controller.

[0067] A mud pressing plate 32 is provided at the lower end of the hydraulic rod of the hydraulic press 31 , and the mud pressing plate 32 is controlled by the hydraulic press 31 to squeeze the sludge downward.

[0068] The mud pressing plate 32 is arranged directly below the gantry 3, and the mud pressing plate 32 is arranged directly above the bearing platform 4 in a level that can be raised and lowered by a hydraulic press 31;

[0069] The mud pressing plate 32 can rise and separate the cover and press it into the sludge frame 1. The mud pressing plate 32 has the same shape as the inner frame of the sludge frame 1, and the mud pressing plate 32 and the sludge frame 1 are matched with a gap, and the gap does not exceed 10mm. In this way, the mud pressing plate 32 can easily squeeze and dehydrate the sludge in the sludge frame 1, and avoid the gap being too large and the sludge overflowing from the gap. Now the gap width is basically within 5mm on each side, which can ensure that sufficient squeezing force is generated on the sludge in the sludge frame 1, and enable the mud pressing plate 32 to be pressed down smoothly into the sludge frame 1 to apply force.

[0070] Existing sludge dewatering machines often require a screening process before sludge dewatering;

[0071] 1. The centrifuge dewatering machine is not suitable for sludge with large pieces, and the dewatering speed is slow, so it is necessary to remove large particles or sludge with large agglomerates first. In addition, the high energy consumption and high speed lead to loud noise. Moreover, when the sludge rotates at high speed, it is easy to be eccentric, causing the centrifuge to shake frequently, which needs to be adjusted in time;

[0072] 2. The filter belt dehydration has insufficient squeezing force, a lot of return sludge, a large amount of backwash water, and poor adaptability to mixed sludge and biochemical sludge;

[0073] 3. Ring-type sludge dewatering machine. If the sludge dewatering machine is not properly maintained, it is easy to be blocked or polluted, thus affecting the dewatering effect and equipment life. It is no longer necessary to select, and the price is higher;

[0074] 4. Plate and frame sludge dewatering machine is difficult to clean after sludge dewatering, and it also needs high-pressure pumping of sludge. It is only suitable for sludge with high water content and requires small sludge particles. It has too many restrictions and is very complicated to operate. It takes up a lot of space and has low dewatering efficiency.

[0075] The characteristic of the device is that it avoids all the disadvantages of the above-mentioned existing equipment, does not limit the sludge quality, and can operate on bagged or liquid sludge. Even mixed sludge with more impurities, and even mixed bagged and liquid sludge, can be dehydrated, which can be completed by pressing down. The amount of sludge treated at one time is large, as long as the sludge frame 1 can hold it, it can be carried out. Generally, several tons of sludge can be treated at one time, the treatment efficiency is high, and no additional pump or high-pressure conveying device is required.

[0076] When the present invention is in use, the hydraulic press 31 is first controlled to drive the mud pressing plate 32 to rise, so as to ensure that the mud pressing plate 32 is located above the mud frame 1 .

[0077] Then the control frame push rod 5 extends to push the sludge frame 1 backward to the rear position of the bearing platform 4, that is, Figure 3 The sludge tank 22 is shown directly above.

[0078] Similarly, the bottom plate push rod 21 is also extended to push the bottom sealing plate 2 backwards, so that the bottom sealing plate 2 is kept in splicing with the sludge frame 1, and the bottom sealing plate 2 is kept in a receiving and closing state with respect to the sludge frame 1.

[0079] At this time, the sludge box 22 is not placed in the rear end position of the sludge frame 1, and then sludge is added into the sludge frame 1, which can be transported by pipeline or unloaded by vehicle. The raw material put into the sludge frame 1 can be bagged sludge or fluid sludge. As long as it flows out of the sludge frame 1, it is the filtered sewage, and the sludge is retained in the sludge frame 1.

[0080] Then the bottom plate push rod 21 and the frame push rod 5 shrink synchronously, and the bottom plate push rod 21 and the frame push rod 5 retract synchronously, pulling the sludge box 22 and the sludge frame 1 forward to the top of the supporting platform 4, and then pulling the sludge frame 1 and the bottom sealing plate 2 back to the front end pressurized dehydration station, that is, the top of the center of the supporting platform 4, that is, directly below the mud pressing plate 32.

[0081] Then the controller 33 controls the hydraulic press 31 to push downward, the mud pressing plate 32 extends downward, and is pressed into the sludge frame 1, and continues to press downward until the hydraulic press 31 applies a specific force, which can be set according to the actual dehydration effect. During this process, the sludge box 22 is pushed into the rear end station of the sludge frame 1.

[0082] After the sludge is dehydrated, 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 filter tank 41, and then the drainage port 42 discharges the sewage into the sewage treatment ditch or pipeline.

[0083] When the sludge in the sludge frame 1 is dehydrated, the frame push rod 5 and the bottom plate push rod 21 extend backward at the same time, pushing the sludge frame 1 and the bottom sealing plate 2 backward, the sludge frame 1 slides backward on the frame guide rail 11, and the bottom sealing plate 2 slides backward on the baffle guide rail 12 until it slides to the rear end station just above the sludge box 22, and then the bottom plate push rod 21 contracts again to pull the bottom sealing plate 2 back forward. At this time, the sludge is heavy and can reach several tons. The squeezed and dehydrated 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 box 22. At this time, dehydrated sludge is obtained, and the sludge dehydration rate can be adjusted according to the control strength of the hydraulic press 31 for easy use.

[0084] The device does not limit the quality and impurities of sludge dehydration, nor does it limit the physical properties of sludge dehydration. The dehydration effect can meet the requirements and is easy to use.

[0085] The front end of this device refers to Figure 3 The left end is the end where the push rod 5 is placed, and the rear end is the end of the sludge box 22 where the sludge is loaded and separated, that is, Figure 3 The orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0086] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
