Description

[0003] However, due to the relatively large particles of some sediment inside the space of the equipment tank body, as the oscillation grid moves up and down, the sediment will move up and down at the middle hole slots of the oscillation grid along with the fluctuating water body. After part of the sediment transfers to the upper surface of the oscillation grid and accumulates, it is easy to cause blockage of the middle hole slots of the oscillation grid. Since the equipment tank body and the cover plate are fixed by multiple groups of bolts, it is rather troublesome to remove them, so the cleaning steps of the oscillation grid are rather cumbersome.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In the present invention, when it is necessary to clean the blocked holes and grooves in the oscillating grille, the staff controls the operation program of the electric actuator push rod. The electric actuator push rod contracts upward to a certain extent, prompting the locking assembly to drive the oscillating grille upward, so that the top of the oscillating grille fits with the bottom of the integrated ring. At this time, multiple groups of upright steel needles fixedly installed at the bottom of the integrated ring can be respectively inserted into multiple groups of holes and grooves on the oscillating grille, squeezing the sediment blocked in the holes and grooves downward to achieve the purpose of dredging the holes and grooves in the oscillating grille.

[0015] 2. In the present invention, when the electric actuator push rod extends and retracts up and down, it drives the oscillating grille to move up and down accordingly, which can correspondingly generate a downward pulling force and an upward squeezing force on the straight telescopic pipe, so that the pipe orifice end of the straight telescopic pipe can be at any height position on the up and down movement path of the oscillating grille. Then, by operating the extraction pump, suction is generated at its input end, sucking the suspension at the opening end of the straight telescopic pipe upward, and discharging it outward along the straight telescopic pipe, the bent pipe, the extraction pump and the second sampling conduit. In addition, in cooperation with the first sampling conduit set at a set position above the sediment, the purpose of sampling the suspension at different depth positions can be achieved.

[0016] 3. In the present invention, the connection, disassembly and assembly between the oscillating grille and the electric actuator push rod are relatively convenient. By squeezing two locking cylinders, they contract and retract into the internal storage groove together with the spring. Then, there are no protrusions on both sides of the connection block. After it is completely inserted into the return-shaped frame, the two storage grooves are respectively superimposed with the two fitting grooves. Then, during the process of the spring restoring its original state, the locking cylinders are pushed towards the fitting grooves to achieve the purpose of locking the connection block and the return-shaped frame. On the contrary, directly applying a pulling force to the connection block away from the position where the return-shaped frame is located can achieve the purpose of simply disassembling and assembling the oscillating grille and the electric actuator push rod.

[0030] Please refer to Figures 1-8 , an embodiment provided by the present invention:

[0031] The sediment resuspension oscillation device includes an equipment tank body 1. A cover plate 2 is fixedly installed at the top of the equipment tank body 1 through bolts. A base 3 is fixedly installed at the bottom of the equipment tank body 1. A first sampling conduit 4 is fixedly connected to a relatively lower position on the surface of the equipment tank body 1. One end of the first sampling conduit 4 is fixedly connected to a hand valve. A lead-out mechanism 5 is fixedly connected to a relatively upper position on the surface of the equipment tank body 1. A gas pressurization system 6 is fixedly connected to the outer surface of the equipment tank body 1. An electric actuator push rod 7 is fixedly connected to the top of the cover plate 2, and the tail end of the electric actuator push rod 7 extends into the interior of the equipment tank body 1. A locking assembly 8 is fixedly connected to the telescopic end of the electric actuator push rod 7. An oscillation grid 9 is fixedly connected to the bottom of the locking assembly 8. Four square-arranged threaded rods 10 are fixedly connected to the bottom of the cover plate 2. Comprehensive sleeves 11 are threadedly sleeved on the outer surfaces of the four threaded rods 10. An I-shaped cylinder 12 is rotatably fitted at the bottom of each of the four comprehensive sleeves 11. A comprehensive ring 13 is fixedly installed at the bottom of the four I-shaped cylinders 12, and the comprehensive ring 13 is located above the oscillation grid 9. A plurality of uniformly arranged upright steel needles 14 are fixedly connected to the bottom of the comprehensive ring 13. The positions and quantities of the plurality of upright steel needles 14 are the same as the positions and quantities of the hole slots in the oscillation grid 9. A through slot 15 is opened at the top of the comprehensive ring 13.

[0032] In this oscillation device, the equipment tank body 1 is made of transparent organic glass or PC material, with a diameter of about 200 MM and a height of about 600 MM. It is fixedly connected to the cover plate 2 through a plurality of bolts. After removing the bolts, the two are in a detachable state. The space inside the equipment tank body 1 is filled with sediment and water. By operating the electric actuator push rod 7, it is prompted to perform up and down telescopic operations accordingly. The oscillation grid 9 is driven to move up and down through the locking assembly 8 to fully stir the suspension solution formed by the sediment and water. Moreover, the electric actuator push rod 7 itself can be speed-adjusted accordingly to adjust the oscillation effect according to requirements. The staff can choose to discharge the suspension solution inside the equipment tank body 1 outward through the first sampling conduit 4 or the lead-out mechanism 5 for sampling;

[0033] Specifically, since the particles of some sediments inside the space of the equipment tank body 1 are relatively large, as the oscillating grid 9 moves up and down, the sediments will move up and down at the middle hole slots of the oscillating grid 9 along with the fluctuating water body. After part of the sediments are transferred to the upper surface of the oscillating grid 9 and accumulate, it is easy to cause blockage at the middle hole slots of the oscillating grid 9. Since the equipment tank body 1 and the cover plate 2 are fixed by multiple groups of bolts, it is rather troublesome to remove them, so the cleaning steps of the oscillating grid 9 are rather cumbersome. In this technical solution, the staff controls the operation program of the electric actuator push rod 7. When it is necessary to clean the blocked hole slots in the oscillating grid 9, the electric actuator push rod 7 contracts upward to a certain extent, prompting the locking assembly 8 to drive the oscillating grid 9 to move upward, so that the top of it fits with the bottom of the comprehensive ring 13. At this time, multiple groups of upright steel needles 14 fixedly installed at the bottom of the comprehensive ring 13 can be respectively inserted into multiple groups of hole slots in the oscillating grid 9, and the sediments blocked in the hole slots are squeezed downward to achieve the purpose of dredging the middle hole slots of the oscillating grid 9;

[0034] More specifically, after the cover plate 2 is removed from the equipment tank body 1, by simultaneously applying a downward rotational force to the four groups of comprehensive sleeves 11, it can be prompted to rotate along the outer surface of the I-shaped cylinder 12 and gradually disengage from the threaded rod 10, and then the disassembly operation of the comprehensive ring 13 and the upright steel needles 14 is completed.

[0035] The structure of the export mechanism 5 includes an extraction pump 16, a bent pipe 17, a second sampling conduit 18, a straight telescopic pipe 19, a lifting rope 20 and a storage plate 21. The storage plate 21 is fixedly installed on the outer surface of the equipment tank body 1. The extraction pump 16 is fixedly connected to the top of the storage plate 21. The bent pipe 17 is fixedly connected to the input end of the extraction pump 16, and the tail end of the bent pipe 17 passes through the outer wall of the equipment tank body 1 and extends above the comprehensive ring 13. The straight telescopic pipe 19 is fixedly connected to the tail end of the bent pipe 17, and the bottom of the straight telescopic pipe 19 penetrates through the inside of the through slot 15. The lifting rope 20 is fixedly connected to the bottom of the straight telescopic pipe 19, and the tail end of the lifting rope 20 is fixedly connected to the top of the oscillating grid 9. The second sampling conduit 18 is fixedly connected to the output end of the extraction pump 16.

[0036] As the electric actuator push rod 7 extends downward, it drives the oscillating grid 9 to move downward accordingly, and can generate a downward pulling force on the straight telescopic tube 19 through the hanging rope 20, so that the straight telescopic tube 19 extends the comprehensive length, and its own open end can move downward accordingly. Conversely, the electric actuator push rod 7 drives the oscillating grid 9 to move upward, and the oscillating grid 9 can generate an upward squeezing force on the straight telescopic tube 19. When the oscillating grid 9 is in contact with the comprehensive ring 13, the straight telescopic tube 19 can be completely located in the through groove 15 and above it after contraction. Therefore, in the present technical solution, the extraction pump 16 can be started at any height position of the up and down movement path of the oscillating grid 9, so that its input end generates suction, and the suspension at the open end of the straight telescopic tube 19 is sucked upward and discharged outward along the straight telescopic tube 19, the bending tube 17, the extraction pump 16 and the second sampling conduit 18. In addition, in conjunction with the first sampling conduit 4 located at a set position above the sediment, the purpose of sampling the suspension at different depths can be achieved.

[0037] The structure of the locking assembly 8 includes a circular frame 22, a connecting block 23 and an interlocking groove 24. The circular frame 22 is fixedly installed in the middle of the upper surface of the oscillation grid 9, and the connecting block 23 is interlocked inside the circular frame 22. There are two groups of interlocking grooves 24, and the two groups of interlocking grooves 24 are respectively opened on both sides of the circular frame 22, and the two groups of interlocking grooves 24 are staggered up and down. The structure of the locking assembly 8 also includes a receiving groove, a spring 25 and a locking cylinder 26. There are two groups of receiving grooves, springs 25 and locking cylinders 26. The two groups of receiving grooves, springs 25 and locking cylinders 26 are respectively opened on both sides of the connecting block 23, and the two groups of springs 25 are respectively fixedly installed on the inner wall of the receiving groove. The two groups of locking cylinders 26 are respectively fixedly connected to one end of the spring 25, and the opposite ends of the two groups of locking cylinders 26 pass through the interior of the two groups of interlocking grooves 24.

[0038] When the locking assembly 8 is assembled, the two sets of locking cylinders 26 are squeezed to cause them to follow the two sets of springs 25 to shrink and return to the space inside the receiving groove. At this time, the connecting block 23 is completely embedded in the space inside the return frame 22. At the same time, the two sets of receiving grooves are superimposed on the two sets of embedding grooves 24, and the squeezing force exerted on the two sets of springs 25 is canceled. Then the springs 25 return to their original state under the action of their own elasticity and reset properties, and push the two sets of locking cylinders 26 outward, causing them to penetrate the interior of the embedding grooves 24, so as to achieve the purpose of locking the connecting block 23 and the return frame 22, so that the connection between the oscillation grid 9 and the electric actuator push rod 7 is stable. Conversely, when the oscillation grid 9 is removed, the same squeezing force is applied to the two sets of locking cylinders 26 to cause them to shrink and return to the interior of the receiving groove, and then the connecting block 23 and the return frame 22 can be separated.

[0039] The structure of the gas pressurization system 6 includes a gas cylinder 27, a first pressure gauge 28, a pressure reducing valve group 29, and a delivery pipe 30. The delivery pipe 30 is fixedly connected to the output end of the gas cylinder 27. There are two sets of the first pressure gauges 28. The two sets of the first pressure gauges 28 are respectively fixedly connected to both ends of the pressure reducing valve group 29. And one set of the first pressure gauges 28 is fixedly connected to one end of the delivery pipe 30. The other end of the other set of the first pressure gauges 28, which is far away from the pressure reducing valve group 29, is fixedly connected with a ventilation pipe, and the tail end of the ventilation pipe extends into the interior of the equipment tank body 1.

[0040] The gas cylinder 27 is filled with nitrogen inside. The pressure reducing valve group 29 is used to reduce the pressure in the gas cylinder 27 to the required pressure range of ≤ 2 MPa, and is connected to the interior of the equipment tank body 1 through the ventilation pipe to pressurize the liquid inside the equipment tank body 1, so as to establish the required pressure. The two sets of the first pressure gauges 28 are used to measure the pressure values in the pipelines at both ends of the pressure reducing valve group 29, so that the adjustment of the pressure reducing valve group 29 has a basis. In addition, the oscillating suspension of the liquid inside the equipment tank body 1 can be carried out under the pressure state, and the sampling can also be carried out under the pressure state to facilitate the selection of continuing the oscillating suspension or stopping the oscillation according to the needs.

[0041] A threaded seat 31 is fixedly installed at the top of the base 3. A water receiving cylinder 32 is placed on the top of the threaded seat 31. The outer surface of the threaded seat 31 is threadedly sleeved with an adjusting sleeve 33. Two sets of vertical rods 34 arranged front and back are fixedly installed at the top of the adjusting sleeve 33. A limiting ring 35 is fixedly installed at the top of the two sets of vertical rods 34.

[0042] The threaded seat 31 itself has a certain height to raise the height position of the water receiving cylinder 32, and then reduce the distance between its top and the second sampling conduit 18, effectively avoiding a large range of splashing of the liquid during sampling. By applying a rotational force in a set direction to the adjusting sleeve 33, it is promoted to rotate upward along the outer surface of the threaded seat 31, which can drive the vertical rods 34 and the limiting ring 35 to move upward together, facilitating the adjustment of the limiting ring 35 to a position above the middle of the water receiving cylinder 32 placed on the top of the threaded seat 31, effectively avoiding the phenomenon of the water receiving cylinder 32 tipping over when being collided.

[0043] Four sets of pulleys 36 arranged in a square are fixedly connected to the bottom of the base 3. A second pressure gauge 37 is fixedly connected to one side of the surface of the equipment tank body 1, and the second pressure gauge 37 is located above the first sampling conduit 4.

[0044] The setting of the pulleys 36 facilitates the movement of the device to the desired position. The setting of the second pressure gauge 37 is used to monitor the pressure value inside the space of the equipment tank body 1 in real time.

[0045] Working principle: The interior space of the equipment tank body 1 is filled with sediment and water. By operating the electric actuator push rod 7, it is driven to perform up and down telescopic operations accordingly. The locking component 8 drives the oscillating grid 9 to move up and down, fully stirring the suspension solution formed by the sediment and water. Moreover, the electric actuator push rod 7 itself can be speed-adjusted accordingly to adjust the oscillation effect according to requirements. When the electric actuator push rod 7 contracts upward to a certain extent, the top of the oscillating grid 9 is made to fit with the bottom of the comprehensive ring 13. At this time, multiple groups of upright steel needles 14 fixedly installed at the bottom of the comprehensive ring 13 can respectively insert into multiple groups of holes in the oscillating grid 9, squeezing the sediment blocked in the holes downward, and the purpose of dredging the holes in the oscillating grid 9 can be achieved. In addition, as the oscillating grid 9 moves up and down, a downward pulling force and an upward squeezing force can be correspondingly generated on the straight telescopic pipe 19, causing the straight telescopic pipe 19 to expand and contract accordingly. The pipe orifice end can be at any height position on the up and down movement path of the oscillating grid 9. Then, by operating the extraction pump 16, the suspension inside the space of the equipment tank body 1 can be extracted through the straight telescopic pipe 19, the bent pipe 17, the extraction pump 16, and the second sampling conduit 18. In addition, in cooperation with the first sampling conduit 4 located at a set position above the sediment, the purpose of sampling the suspension at different depth positions can be achieved. In addition, in cooperation with the gas pressurization system 6, the liquid in the tank is pressurized to establish the required pressure.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
