Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment, in particular to sludge dewatering equipment for river ecological management. Background Art

[0002] In urban and rural river management, the sludge that accumulates over the years contains large amounts of organic matter, heavy metals, nitrogen, phosphorus, and other pollutants. If not cleaned promptly, it can easily lead to water quality deterioration, the formation of black and odorous water bodies, and even affect the recovery of aquatic ecosystems, seriously hindering the improvement of water environment quality and the restoration of river ecological functions. Therefore, efficient, safe, and environmentally friendly dewatering of bottom sludge has become a key step in the process of river ecological management. Currently, commonly used sludge dewatering methods include natural drying, plate and frame filter pressing, belt filter pressing, and centrifugal dewatering.

[0003] After searching, the utility model patent with publication number CN217535796U discloses a sludge dewatering device for water conservancy river ecological management. By turning on the drive motor, the ball screw is driven to rotate, and the ball screw drives the sliding block to move back and forth left and right, thereby driving the cleaning plate and brush to move to achieve a cleaning effect.

In the traditional treatment process, impurity cleaning, sludge transfer, and filter press feeding need to be completed manually in sections, and repeated transfer is highly dependent. River sludge is often mixed with large impurities such as branches and stones. If it enters the dewatering equipment directly, it is easy to cause filter plate blockage and accumulation in the filter press cavity, affecting continuous operation.

[0023] One sliding block is fixed to the inclined block, and the other sliding block is connected with a reinforcing rod for reinforcing the outer frame of the filter plate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Before dehydration, the present invention slides from the fixed frame to the position of the impurity discharge port, and the sludge is passed into the sewage blocking chamber for shearing and crushing, deagglomeration treatment, and the sludge flocculent particles pass through the filter plate and fall toward the seepage cavity; then the material frame slides into the fixed frame, and then the rotation of the filter plate drives the larger solids on the filter plate to fall into the material frame, avoiding system stagnation caused by filter plate blockage or impurity accumulation; the sludge flocculent particles slide into the mud collecting box, which is convenient for collecting the sludge flocculent particles, and the sewage seeps into the seepage cavity, realizing the preliminary static dehydration of the sludge in the mud collecting box, and then the mud collecting box is guided along the guide roller on the outside. The rail slides into the middle cavity until it reaches the feeding port of the feeding channel. The feeding channel lifts the sludge floc particles to the top discharge port of the other side cavity and enters the dispersion box. The dispersion rollers rotating in different directions break up the particle agglomeration and enter between two adjacent dispersion rollers, so that the sludge is evenly distributed after passing through multiple dispersion channels, avoiding the accumulation of sludge particles during dehydration. The dehydration component is then used for dehydration and filtration, which improves the filtration effect, solves the problems of concentrated particle feeding and incomplete edge dehydration, and improves the load uniformity of the filtration area. The entire process is carried out in sequence, complete, continuous and coordinated operation.

[0026] 2. The blocking plate slides on the bottom of the seepage plate, opening the small holes on the seepage plate. The water from the sludge flocs on the seepage plate seeps into the seepage cavity, where it is left to stand for dehydration. The blocking plate then slides closed. The mud collecting box slides on the guide rail, driving the mud collecting box from the collecting position to the loading position. The seepage plate rotates and opens, changing from a horizontal position to an inclined position and finally to a vertical position, thereby dumping the sludge flocs.

[0027] 3. When the sludge particles pass through the filter plate, the reinforcing rod is inserted into the filter plate. The inclined block and the reinforcing rod are close to the driving cavity. Then the filter plate flips with the rotating shaft as the center to dump the attached large particles of impurities. In this process, the filter plate rotates to the dumping angle, and the sliding block moves in the opposite direction to push the reinforcing rod into the reinforcement hole outside the rotating center of the filter plate to prevent the filter plate from being deformed or deflected due to structural fatigue or heavy impact during flipping, thereby extending the service life of the device.

DETAILED DESCRIPTION

[0037] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0038] See also Figure 1-Figure 7 As shown, the present invention provides a sludge dewatering device for river ecological management, including a treatment box 1. The treatment box 1 has three chambers inside. The chamber on one side is connected to a dirt holding chamber 4 via two sets of oil cylinders. An agitator 8 for agitating and breaking large sludge is installed inside the dirt holding chamber 4. A nozzle 7 for spraying flocculant is installed at the top of the inner cavity of the dirt holding chamber 4. A filter plate 31 that can be flipped and rotated for sludge particles to pass through is provided below the agitator 8. A fixed frame 9 is installed at the bottom of the dirt holding chamber 4. A material frame for collecting residual impurities dropped by the filter plate 31 when it rotates is slidably installed inside the fixed frame 9. An elastic pad 12 connected to the seepage chamber 10 is provided at the bottom of the fixed frame 9.

[0039] A seepage chamber 10 is provided below the fixed frame 9. A sludge collecting box 11 for collecting sludge particles is slidably provided inside the seepage chamber 10. The seepage chamber 10 is communicated with the sludge collecting box 11. Guide rails 14 for directional rolling of the rollers on the sludge collecting box 11 are provided in one side chamber and the middle chamber. A feeding channel 15 for conveying sludge particles to the top of the other side chamber is installed in the middle chamber.

[0040] The discharge end at the top of the feeding channel 15 is connected to a uniform material distribution component, which includes a dispersion box 16. A plurality of dispersion rollers 17 are installed inside the dispersion box 16. The rotation directions of two adjacent dispersion rollers 17 are different, and the discharging directions of two adjacent dispersion rollers 17 are both provided with a dispersion channel 18. The end of the dispersion channel 18 is provided with a dehydration component.

[0041] When dewatering river sludge, the river sludge is first pumped into the sewage holding chamber 4 of the side cavity by means of pumping equipment. During this process, the agitator 8 rotates continuously, and the nozzle 7 on the top sprays flocculants to shear, crush and deagglomerate the large lumps of mud or impurities entering, preventing blockage by large sediments.

[0042] The reagent and sludge are fully mixed and reacted during stirring, prompting the fine particles to form stable flocs, which enhances subsequent sedimentation and filtration efficiency. The sludge flocs pass through the filter plate 31 smoothly and fall down, while larger solid impurities (such as branches and stones) remain on the filter plate 31.

[0043] Initially, the material frame slides from the fixed frame 9 to the position of the impurity discharge port 5. After the sludge flocculent particles finish falling, the material frame slides into the fixed frame 9. Then, through the rotation of the filter plate 31, the larger solids on the filter plate 31 fall into the material frame, avoiding system stagnation caused by blockage of the filter plate 31 or accumulation of impurities.

[0044] In the initial state, the mud collecting box 11 rolls to the inside of the seepage cavity 10, as shown in FIG. Figure 2 As shown, at this time, the mud collecting box 11 and the seepage chamber 10 are collinear in the vertical direction, and the sludge floc particles fall toward the seepage chamber 10 below and slide into the mud collecting box 11, which facilitates the collection of the sludge floc particles, while the sewage seeps into the seepage chamber 10, achieving preliminary static dehydration of the sludge in the mud collecting box 11, and then the mud collecting box 11 slides into the middle chamber along the guide rail 14 through the outer rollers until it reaches the loading port of the loading channel 15, and the sludge floc particles are lifted to the top discharge port of the other side chamber by means of the loading channel 15;

[0045] It enters the dispersion box 16, and the dispersion rollers 17 rotating in different directions break up the agglomeration of particles, and enter between two adjacent dispersion rollers 17, so that the sludge is evenly distributed after passing through multiple dispersion channels 18, avoiding the accumulation of sludge particles during dehydration, and then dehydration and filtration are carried out through the dehydration component to improve the filtration effect, solve the problems of concentrated particle feeding and incomplete edge (local) dehydration, and improve the load uniformity of the filtration area. The whole process is carried out in sequence, completely, continuously and coordinated.

[0046] See Figure 1 and Figure 2 As shown, the dewatering assembly includes a dewatering plate 20 pushed by a lifting push rod installed in another cavity. A mud pressing top plate 33 communicating with the dispersion channel 18 is provided above the dewatering plate 20. A dewatering cavity 19 is provided between the mud pressing top plate 33 and the dewatering plate 20. The outer surface of the processing box 1 is provided with a mud discharge port 2 flush with the height of the dewatering plate 20.

[0047] The surface of the mud pressing top plate 33 is provided with a mud inlet 34 communicating with the dispersion channel 18, and the inner cavity of the mud pressing top plate 33 is installed with an electric push rod 36, the pushing end of the electric push rod 36 is connected to an adjustment plate 35 that slides within the mud pressing top plate 33;

[0048] The surface of the adjustment plate 35 is provided with a hole groove with the same size as the mud inlet 34;

[0049] During dehydration, the flow cross-sectional area of ​​the mud inlet 34 is dynamically controlled by controlling the left and right sliding of the adjustment plate 35, thereby achieving precise control of the sludge feeding speed and feeding amount. The mud feeding amount can be automatically adjusted according to different sludge states (concentration, granularity, fluidity), avoiding problems such as uneven material pressing in the dehydration chamber, poor filtration, equipment blockage, or reduced filter press efficiency caused by feeding too fast or too slow;

[0050] After entering the dewatering chamber 19, the dewatering plate 20 moves upward, and the sludge is squeezed in the dewatering chamber 19, with a significant filtration effect. The dewatering plate 20 moves downward and is flush with the mud discharge port 2 set outside the processing box 1. The push plate on the inner wall of the chamber pushes the mud cake after filtration, thereby realizing rapid mud unloading after dehydration.

[0051] See Figure 4 As shown, the outer surface of the seepage cavity 10 is provided with a matching groove 22 that is slidably adapted to the mud collecting box 11, and the side of the mud collecting box 11 is provided with a notch 23 that enters the top of the feeding port at the bottom of the feeding channel 15;

[0052] The sludge collecting box 11 slides in the seepage chamber 10 and transports the collected sludge flocculent particles to above the feeding port of the feeding channel 15 .

[0053] See Figure 5 As shown, a seepage plate 21 is rotatably installed inside the mud collecting box 11, and a blocking plate 24 is slidably provided on the bottom surface of the seepage plate 21. The seepage plate 21 is provided with a plurality of small holes for liquid penetration;

[0054] Since the sludge collecting box 11 is vertically aligned with the seepage chamber 10, the blocking plate 24 slides on the bottom surface of the seepage plate 21, causing the small holes on the seepage plate 21 to open. The seepage rate is controlled according to the size of the opening, and the water from the sludge flocs on the seepage plate 21 seeps into the seepage chamber 10. Then the blocking plate 24 slides closed and reaches the feeding port of the feeding channel 15. The seepage plate 21 rotates open, changing from a horizontal state to an inclined state and finally to a vertical state, thereby realizing the dumping of the sludge flocs.

[0055] After loading, the mud collecting box 11 returns to the initial position to continue collecting mud.

[0056] See Figure 1-Figure 3 As shown, an opening 13 is provided between the one side cavity and the middle cavity for the mud collecting box 11 to slide through;

[0057] The mud collecting box 11 enters the middle cavity through the opening 13, which facilitates the discharge of mud from the mud collecting box 11;

[0058] The feed end of the dirt-blocking chamber 4 is connected to the liquid inlet end of the treatment box 1, and a sealing plate 6 is provided inside the dirt-blocking chamber 4 to block the feed end of the dirt-blocking chamber 4. The sealing plate 6 is pushed by the lifting unit;

[0059] The sealing plate 6 is opened, and the river sludge enters the sewage holding chamber 4 after the liquid inlet end and the feed end are connected, and then the sealing plate 6 slides closed;

[0060] A through opening 3 is provided on the top of one side of the cavity, and a debris discharge opening 5 is provided on the front side of the cavity. The debris discharge opening 5 is at the same height as the material frame.

[0061] After the material frame collects larger solid impurities (such as branches and stones), it slides to pass through the impurity discharge port 5 and is exposed on the front side of the processing box 1 for manual or machine cleaning.

[0062] See Figure 2 and Figure 6 As shown, a filter plate 31 for filtering large particles of impurities is rotatably provided at the bottom of the dirt-blocking chamber 4, and a driving chamber 26 is provided in the inner cavity at the bottom of the dirt-blocking chamber 4. An inclined block 25 is slidably provided above the filter plate 31 in the same direction as the bottom of the dirt-blocking chamber 4.

[0063] A positioning guide transmission assembly is provided inside the drive chamber 26. The positioning guide transmission assembly includes a second screw 28. A first screw 27 is rotatably provided above the second screw 28 and in the opposite direction of its thread. The second screw 28 and the first screw 27 are fixedly sleeved with mutually meshing gears 29 on their exteriors. The exteriors of the second screw 28 and the first screw 27 are both threadedly sleeved with sliding blocks 32 that slide in contact with the inner wall of the drive chamber 26.

[0064] One sliding block 32 is fixed to the inclined block 25, and the other sliding block 32 is connected to a reinforcing rod 30 for reinforcing the outer frame of the filter plate 31. The reinforcing rod 30 is inserted into the reinforcing hole on the outer side of the filter plate 31;

[0065] When the filter plate 31 is horizontal, it is in the working filtering state. At this time, the inclined block 25 is located above the filter plate 31. The inclined block 25 is consistent with the inner slope of the dirt-blocking chamber 4, guiding the sludge flocculent particles to the filter plate 31. At this time, the reinforcing rod 30 is inserted into the filter plate 31 to ensure the stability of the filter plate 31.

[0066] The drive system is started, and the two gears 29 are engaged, driving the screw rod 28 and the screw rod 1 27 to rotate simultaneously, driving the corresponding sliding block 32 to slide. At this time, the inclined block 25 and the reinforcing rod 30 are both close to the drive chamber 26. Then the filter plate 31 flips around the rotation axis to dump the attached large particles of impurities. In this process, the filter plate 31 rotates to the dumping angle, and the sliding block 32 moves in the opposite direction, pushing the reinforcing rod 30 into the reinforcement hole outside the rotation center of the filter plate 31, preventing the filter plate 31 from deformation or deflection due to structural fatigue or heavy impact during flipping, thereby extending the service life of the device;

[0067] When the system determines that the filter holes are clogged or the processing cycle is completed, it will automatically flip and dump the filter, reducing the number of manual cleaning times and improving the system's continuous operation capability.

[0068] When the present invention is in use, before dehydration, the material frame slides from the fixed frame 9 to the position of the impurity discharge port 5, and the sludge is passed into the dirt blocking chamber 4 for shearing and crushing, deagglomeration treatment, and the sludge flocculent particles pass through the filter plate 31 and fall toward the seepage cavity 10; then the material frame slides into the fixed frame 9, and then the rotation of the filter plate 31 drives the larger solids on the filter plate 31 to fall into the material frame, avoiding the system stagnation caused by the blockage of the filter plate 31 or the accumulation of impurities; the sludge flocculent particles slide into the mud collecting box 11, which is convenient for collecting the sludge flocculent particles, and the sewage seeps into the seepage cavity 10, realizing the preliminary static dehydration of the sludge in the mud collecting box 11, and then the mud collecting box 11 passes through the outside The roller slides into the middle cavity along the guide rail 14 until it reaches the feeding port of the feeding channel 15. The sludge floc particles are lifted to the top discharge port of the cavity on the other side by means of the feeding channel 15 and enter the dispersion box 16. The particles are broken up by the dispersion rollers 17 rotating in different directions, and enter between two adjacent dispersion rollers 17, so that the sludge is evenly distributed after passing through multiple dispersion channels 18, avoiding the accumulation of sludge particles during dehydration, and then dehydration and filtration are carried out through the dehydration component to improve the filtration effect, solve the problems of concentrated particle feeding and incomplete edge dehydration, and improve the load uniformity of the filtration area. The whole process is carried out in sequence, complete, continuous and coordinated operation;

[0069] The blocking plate 24 slides on the bottom surface of the seepage plate 21, so that the small holes on the seepage plate 21 are opened, and the water in the sludge floccules on the seepage plate 21 seeps into the seepage chamber 10, and then the blocking plate 24 slides closed. The mud collecting box 11 slides on the guide rail 14, driving the mud collecting box 11 from the collecting position to the loading position. The seepage plate 21 rotates and opens, changing from a horizontal state to an inclined state and finally to a vertical state, thereby realizing the dumping of the sludge floccules.

[0070] The sludge particles pass through the filter plate 31. At this time, the reinforcing rod 30 is inserted into the filter plate 31. The inclined block 25 and the reinforcing rod 30 are both close to the driving chamber 26. Then the filter plate 31 flips around the rotating shaft to dump the attached large particles of impurities. In this process, the filter plate 31 rotates to the dumping angle, and the sliding block 32 moves in the opposite direction, pushing the reinforcing rod 30 into the reinforcement hole outside the rotation center of the filter plate 31, preventing the filter plate 31 from being deformed or deflected due to structural fatigue or heavy impact during flipping, thereby enhancing the service life of the device.
