Description

Technical Field

[0001] The invention relates to the field of hydraulic engineering silt removal devices, and in particular to a hydraulic engineering silt removal device that facilitates solid-liquid separation and a use method thereof. Background Art

[0002] Water conservancy projects usually refer to projects built to prevent and control water disasters and develop and utilize water resources. During the water conservancy project process, it is usually necessary to remove impurities such as silt mixed in the water. At the same time, during the removal process, the silt and other impurities are separated from the water for solid-liquid separation, and then the water conservancy project dredging equipment is used.

[0003] The prior art water conservancy project dredging device usually uses a dewatering device to separate impurities such as silt from the water phase. The dewatering equipment includes a dewatering box and a water-throwing assembly. The dewatering box is usually provided with a box door, a feed port and a drain port. Then, impurities such as silt and a water mixture are added to the interior of the dewatering box through the feed port, and then enter the interior of the water-throwing assembly to throw out the water inside the impurities such as silt. The water-throwing assembly usually includes a centrifugal cylinder and a driving member. The centrifugal cylinder is installed on the driving member. The centrifugal cylinder is then driven by the driving member to rotate the impurities such as silt inside the centrifugal cylinder, so that the water is thrown out to perform solid-liquid separation operations on the impurities such as silt.

[0004] When sludge and other impurities need to be taken out after being thrown out of water for a certain period of time, the box door is usually opened first, and then the staff needs to disassemble the centrifugal cylinder and the driving part, and then take out the centrifugal cylinder to pour out the impurities, and then install the centrifugal cylinder on the driving part for use. However, this method will result in cumbersome operation, which will increase the labor intensity of the staff accordingly. Therefore, it is necessary for the water conservancy project dredging device to directly take out the centrifugal cylinder to improve the efficiency of pouring out sludge and other impurities after solid-liquid separation.

[0062] The present invention also provides a usage method of a water conservancy project dredging device facilitating solid-liquid separation, including the following specific usage steps:

[0063] Step 1: Move the dehydration tank body to the operation area, lock the shielding door through the positioning mechanism to ensure that the square groove is in a closed state. Load the preset parameters through the control module. The preset parameters include the feeding height threshold H set, the holding pressure of the hydraulic cylinder P max, and the target rotational speed of the centrifuge cylinder ω ref. Inject the sludge mixture into the second box body through the feeding port. The sludge mixture accumulates on the material receiving part and is located between the extrusion plate and the bearing plate. Part of the water and sludge flow downward along the inside of the filter holes, and then the water and sludge fall into the inside of the centrifuge cylinder and then flow out through the holes on the centrifuge cylinder to the bottom end of the inner wall of the first box body. The flow sensor monitors the accumulation height H in real time. If H≥H set, the control module sends an instruction to the hydraulic drive module to make the extrusion plate approach the bearing plate to extrude the accumulated sludge mixture. The liquid water flows into the centrifuge cylinder through the filter holes, and the solid matter remains on the material receiving part. The speed formula of the piston rod on the hydraulic cylinder is:

[0064] v = K p*(H - H set);

[0065] Step 2: When the displacement sensor detects that the stroke of the hydraulic cylinder reaches L max, the control module executes the unloading instruction to retract the hydraulic cylinder. The driving frame drives the extrusion plate to reset, pushes the connecting frame to horizontally slide the material receiving part to move backward along the material leakage groove, the elastic part is stretched, the material leakage groove is opened, and the sludge mixture after preliminary extrusion falls into the inside of the centrifuge cylinder. After timing for t seconds, the hydraulic cylinder extends again, the elastic part rebounds, and the material receiving part resets to block the material leakage groove. When the displacement sensor detects that the material receiving part is away from the inside of the material leakage groove, a feeding completion signal is generated;

[0066] Step 3: After the control module receives the signal indicating that the feeding is completed, the servo driver drives the servo motor using the SVPWM algorithm to accelerate the centrifuge cylinder to ω_ref. During rotation, the torque sensor continuously detects the load torque T. If T > T_max, the rotational speed is dynamically adjusted. The vibration sensor continuously monitors. If the amplitude A ≥ A_max, an emergency stop is performed according to ω = ω_current*e^(-kt). Then, under the action of centrifugal force, the remaining moisture is thrown out of the centrifuge cylinder to the bottom of the first box body, and the brush synchronously sweeps the cylinder wall. After the set water throwing time t arrives, the control module controls the servo motor to stop the rotation of the centrifuge cylinder. The formula for torque adaptive deceleration is:

[0067]

[0068] Step 4: Manually pull the limit frame away from the sliding plug board, at this time, the position limitation of the shielding door is released, and then push the shielding door to slide, so that the inside of the square groove is exposed. At the same time, the shielding door drives the series part to move, and the series part drives the moving part, the limiting part and the linkage part to move. Then, the limiting part moves away from the centrifuge cylinder, and the position limitation of the centrifuge cylinder can be released. At the same time, during the movement of the limiting part, the traction plate is pushed to move, so that the traction plate pulls the traction rope, and then pulls the connecting column. The connecting column pulls the blocking plate to move, so that the blocking plate releases the blockage of the inside of the fixed pipe, and the separated water flows out. Then, the centrifuge cylinder is directly lifted out by using the inside of the square groove, and the separated sludge and garbage are respectively poured at the designated positions to complete the solid-liquid separation of the sludge and garbage.

[0069] The technical effects and advantages of the present invention:

[0070] (1) The present invention uses the setting method in which the dehydration box body, the shielding door, the square groove, the support plate, the fixed ring, the positioning column, the series part, the moving part, the limiting part and the linkage part cooperate with each other. When the shielding door is pushed and the inside of the square groove is opened, the series part is driven to move, and the series part drives the moving part, the limiting part and the linkage part to move, so that the limiting part moves away from the centrifuge cylinder, and the position limitation of the fixed ring is released. Then, it is beneficial to release the position limitation of the centrifuge cylinder while opening the shielding door, so that the centrifuge cylinder can be directly taken out from the inside of the dehydration box body, and the separated sludge and other impurities can be poured out, which is convenient for reducing the labor intensity of the staff and is easy to operate;

[0071] (2) The present invention uses the setting method in which the first box body, the second box body, the top plate, the shielding door, the first plate body, the second plate body, the insertion plate, the fixed seat and the mounting column cooperate with each other. The first box body, the second box body and the top plate make the dehydration box body be connected in a spliced manner, the insertion plate makes the first box body, the second box body and the top plate be connected in series, and the mounting column locks and fixes the insertion plate and the fixed seat. Then, it is beneficial to disassemble the dehydration box body, which is convenient for separately cleaning its inside and is easy to operate;

[0072] (3) The present invention utilizes the arrangement mode of matching the extrusion mechanism, the connecting frame, the supporting part, the receiving part, the sliding part, the elastic part, the hanging part, the arc part and the brush hairs. The extrusion plate and the bearing plate extrude the sludge mixture, so that the water overflows and part of the sludge is separated from the garbage impurities. The receiving part receives the sludge mixture. The driving frame pushes the supporting part to move, thereby causing the sliding part and the receiving part to move. The elastic part deforms to generate a rebound force, so that the inside of the leakage trough is opened, which is beneficial to the preliminary squeezing and separation of sludge and other impurities, and then the water is thrown away to improve the solid-liquid separation quality of the sludge. At the same time, it is beneficial to automatically draw the receiving part out of the leakage trough when the extrusion plate returns to the movement after the extrusion is completed, so that the sludge mixture can be discharged. After the discharge is completed, the elastic part causes the receiving part to automatically block the inside of the leakage trough, and at the same time, it is beneficial to brush and clean the outside of the centrifugal cylinder.

[0073] (4) The present invention utilizes a setting mode in which the drainage mechanism and the linkage part cooperate with each other. When the shielding door pushes the series part to move, the linkage part moves along with it, and the linkage part pushes the traction plate to move, so that the traction rope pulls the blocking plate to move, so that the interior of the fixed pipe is opened, which is conducive to opening the interior of the fixed pipe and discharging the separated water while the shielding door is opened to release the limit of the centrifugal cylinder, and the operation is convenient;

[0074] (5) The present invention utilizes a sliding plate, a positioning frame, a limiting frame, a block, a guide frame, an annular plate and a second spring in a coordinated arrangement. The sliding plate and the positioning frame position the connection of the shielding door, and the limiting frame limits the relative position of the positioning frame and the sliding plate, thereby facilitating the limiting of the shielding door and the limiting portion so as to install and use the centrifuge cylinder.

[0097] Usage method of the present invention:

[0098] Move the dewatering box body 1 to the operation area. Lock the shielding door 14 through the positioning mechanism 7 to ensure that the square groove is in a closed state. Load preset parameters through the use of the control module. The preset parameters include the feeding height threshold H set, the holding pressure P max of the hydraulic cylinder 21, and the target rotation speed ωref of the centrifugal cylinder 34. Inject the sludge mixture into the second box body 12 through the feeding port. The sludge mixture accumulates on the material receiving part 412 and is located between the extrusion plate 23 and the bearing plate 25. Part of the water and sludge flow downward along the inside of the filter holes 413. Then, the water and sludge fall into the inside of the centrifugal cylinder 34 and then flow out through the holes on the centrifugal cylinder 34 to the bottom end of the inner wall of the first box body 11. The flow sensor monitors the accumulation height H in real time. If H≥H set, the control module sends an instruction to the hydraulic drive module to make the extrusion plate 23 approach the bearing plate 25 to extrude the accumulated sludge mixture. The liquid water flows into the centrifugal cylinder 34 through the filter holes 413, and the solid matter remains on the material receiving part 412. The speed formula of the piston rod on the hydraulic cylinder 21 is:

[0099] v = K p*(H - H set);

[0100] When the displacement sensor detects that the stroke of the hydraulic cylinder 21 reaches L max, the control module executes the unloading instruction, causing the hydraulic cylinder 21 to retract. The driving frame 22 drives the extrusion plate 23 to reset, pushing the connecting frame 41 to horizontally slide the material receiving part 412 to move backward along the material leakage groove. The elastic part 415 is stretched, and the material leakage groove opens. The preliminarily extruded sludge mixture falls into the interior of the centrifugal cylinder 34. After t seconds of timing, the hydraulic cylinder 21 extends again, the elastic part 415 rebounds, and the material receiving part 412 resets to block the material leakage groove. When the displacement sensor detects that the material receiving part 412 is away from the inside of the material leakage groove, a feed completion signal is generated.

[0101] After the control module receives the feed completion signal, the servo driver uses the SVPWM algorithm to drive the servo motor 33 to accelerate the centrifugal cylinder 34 to ωref. During rotation, the torque sensor continuously detects the load torque T. If T > T_max, the rotational speed is dynamically trimmed. The vibration sensor continuously monitors. If the amplitude A ≥ A_max, an emergency stop is performed according to ω = ω_current*e^(-kt). Then, under the action of centrifugal force, the remaining moisture is thrown out of the centrifugal cylinder 34 to the bottom of the first box body 11, and the brush hairs 418 synchronously clean the cylinder wall. After the set water throwing time t arrives, the control module controls the servo motor 33 to stop the rotation of the centrifugal cylinder 34. Among them, the formula for torque adaptive deceleration is:

[0102]

[0103] Manually pull the limit frame 73 to disengage from the sliding plug board 71. At this time, the position limit of the shielding door 14 is released. Then push the shielding door 14 to slide, exposing the inside of the square groove. At the same time, the shielding door 14 drives the series part 511 to move. The series part 511 drives the moving part 512, the limiting part 513 and the linkage part 514 to move. Thus, the limiting part 513 moves away from the centrifugal cylinder 34, and the position limit of the centrifugal cylinder 34 can be released. At the same time, during the movement of the limiting part 513, the traction plate 68 is pushed to move, so that the traction plate 68 pulls the traction rope 67, and then pulls the connecting column 64. The connecting column 64 pulls the blocking plate 65 to move, so that the blocking plate 65 releases the blockage of the inside of the fixed pipe 62. The separated water flows out. Then, directly use the inside of the square groove to lift the centrifugal cylinder 34 upward and take it out, and pour the separated sludge and garbage at the designated positions respectively to complete the solid-liquid separation of the sludge and garbage.
