Description

Technical Field

[0001] The invention belongs to the technical field of riverbed sediment cleaning, and in particular relates to an integrated sediment separation pump station. Background Art

[0002] The river cleaning sediment separation pump station is a device used to clean the sediment particles deposited at the bottom of the river. It integrates the functions of liquid extraction and sediment separation. When in use, a dredger equipped with a dredger suction device is used to suck the sediment deposited on the river bottom into the dredger storage bin on the hull. The dredger is then moved to the vicinity of the pump station. The pump station uses a centrifugal pump to extract the liquid containing sediment solid particles in the dredger storage bin and treats it using the dredger separation equipment.

[0003] The existing river cleaning sediment separation pump station is set on one side of the river channel. It is unable to directly extract the sediment from the riverbed for treatment. It is necessary to use a suction dredger to carry the riverbed sediment back and forth, then transport it to the shore, and then use the river cleaning sediment separation pump station to treat the liquid containing sediment particles extracted by the suction dredger. The functions are scattered, not only the cost is high, but also the suction dredger is required to carry the riverbed sediment back and forth, which leads to poor continuous operation capacity, low efficiency, lack of integration and optimization, and poor maneuverability. In addition, when the existing river cleaning sediment separation pump station uses a centrifugal pump to extract the liquid containing sediment particles from the suction dredger for treatment, a large amount of sediment particles in the liquid will directly enter the pump body, which will cause serious wear and tear on the equipment, thereby shortening the service life of the equipment and increasing the cost of maintenance and replacement.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments. Example

[0028] The embodiment provides a sediment separation integrated pump station with a unique structure and ingenious design. Figure 1-7 As shown, it includes a cleaning ship 1, a sediment treatment unit, an alternating discharge device 4 and a transfer device 5. The cleaning ship 1 is matched with a sediment storage bin 11. The sediment treatment unit includes a sediment extraction device 2, a sediment separation device 3 and a centrifugal pump. The sediment separation device 3 includes a separation barrel 31 arranged above the alternating discharge device 4. The lower section of the separation barrel 31 is conical and is provided with a discharge port connected to the alternating discharge device 4. A water pumping pipe 33 is vertically installed on the top of the separation barrel 31. One end of the water pumping pipe 33 extends downward into the separation barrel 31, and the other end is connected to the suction end of the centrifugal pump; a mud extraction pipe 32 connected to the interior of the separation barrel 31 is tangentially provided on one side of the upper section of the separation barrel 31, and the other end of the mud extraction pipe 32 is connected to the sediment extraction device 2. The sediment extraction device 2 is vertically slidably installed at the stern of the cleaning ship 1 for extracting riverbed sediment. Specifically: A hanger 12 is provided at the rear side of the cleaning boat 1, and the hanger 12 is fixedly connected to the cleaning boat 1. The silt extraction device 2 is installed in the hanger 12 along the vertical sliding direction, and is connected to the lifting drive assembly 24 in a transmission manner. The height of the silt extraction device 2 immersed in the water can be controlled by the lifting drive assembly 24. The silt extraction device 2 includes an outer frame 211, a suction pipe 214, a breaking pipe 215 and a rotating drive assembly 24. The outer frame 211 is installed in the hanger 12 along the vertical sliding direction, and is connected to the lifting drive assembly 24 to control the height of the outer frame 211. There are many ways to slide and install the outer frame 211, for example: a lifting track is vertically provided on the inner edge of the left and right sides of the outer frame 211, and sliders are matched and installed on the outer end surfaces of the left and right sides of the outer frame 211, and the sliders are matched and installed in the lifting tracks on the adjacent sides; there are many structures of the lifting drive assembly 24, for example: the lifting drive assembly 24 is an existing winch device, the winch device is installed on the top of the hanger 12, and the traction rope of the winch device is connected to the outer frame 211, and when the winch device releases the traction rope, the outer frame 211 will rely on its own weight to descend along the hanger 12.

[0029] The top end of the scattering tube 215 is rotatably installed in the outer frame 211 and is transmission-connected to the rotating drive assembly 24. Specifically, a fixing sleeve 212 is vertically provided inside the outer frame 211, and a plurality of fixing rods 213 are evenly spaced along the circumference on the outer ring surface of the fixing sleeve 212. The other end of the fixing rod 213 is fixedly connected to the inner wall of the outer frame 211. The top end of the scattering tube 215 is rotatably installed in the fixing sleeve 212 through a bearing 25, and scattering teeth 216 are provided on the outer ring surface of the bottom end of the scattering tube 215.

[0030] The rotary drive device includes a drive motor fixedly mounted on the rear end face of the outer frame 211. The motor shaft of the drive motor is arranged downward and is provided with a drive gear. A fixed sleeve 212 on the scattering tube 215 below the outer frame 211 is provided with a driven gear, and the driven gear is connected to the drive gear through a chain transmission.

[0031] The suction pipe 214 is rotatably installed in the scattering pipe 215, and the top end of the suction pipe 214 extends out of the scattering pipe 215 and is connected to a suction hose, the other end of the suction hose is connected to the water pumping pipe 33, and there are many ways to rotatably install the suction pipe 214 in the scattering pipe 215, for example: a plurality of shaft sleeves 26 are vertically spaced outside the water pumping pipe 33, and the shaft sleeves 26 are matched and rotatably installed in the scattering pipe 215. When in use, after the sediment extraction device 2 descends to the river bottom, the centrifugal pump is turned on, and negative pressure is generated in the separation barrel 31 to draw the river bottom sediment into the separation barrel 31 through the mud extraction pipe 32, the mud extraction hose 34 and the sediment extraction device 2. Since the water pumping pipe 33 is tangentially arranged along the separation barrel 31, the river water mixed with sediment will enter the separation barrel 31 through the water pumping pipe 33 and will be discharged from the separation barrel 31. 1 forms a rotating water flow. Under the action of the rotating water flow, the silt particles in the water flow will be thrown off the inner wall of the separation barrel 31 by the centrifugal force, and then fall along the inner wall of the separation barrel 31 and be discharged into the alternating discharge device 4. The remaining liquid will be pumped out and discharged through the pumping pipe 33 by the centrifugal pump. When in use, the centrifugal pump is used as a power source to pump the riverbed silt into the separation barrel 31 to separate the silt particles, and the separated liquid is pumped out. When the liquid is pumped out and discharged by the centrifugal pump, since most of the silt particles in the liquid are separated in the separation barrel 31 and discharged into the alternating discharge device 4, the centrifugal pump will not be damaged. Furthermore, when sucking the silt deposited on the riverbed, the rotary drive device drives the scattering roller to rotate to stir and lift up the deposited silt, thereby facilitating suction.

[0032] The alternating discharge device 4 includes a temporary storage box 41, a sealing assembly 42 and a push-pull mechanism 43. The temporary storage box 41 is arranged on the cleaning ship 1 at the rear side of the storage bin 11. Two independent storage chambers 411 are arranged in the temporary storage box 41 along the lateral interval. The temporary storage boxes 41 on the upper and lower sides of the storage box are respectively provided with mud inlets 412 and mud outlets 413 connected thereto. The mud inlets 412 of the two storage chambers 411 are both connected to the discharge port of the separation barrel 31; the sealing assembly 42 is installed at both ends of the temporary storage box 41, and the sealing assembly 42 is transmission-connected with the push-pull mechanism 43. The push-pull mechanism 43 can synchronously control the mud inlets 412 and mud outlets 413 at the upper and lower ends of the two storage chambers 411 through the two sealing assemblies 42 to alternately open and close, and the mud inlets 412 of the two storage chambers 411 and the mud outlets 413 of the two storage chambers 411 are alternately opened and closed. Specifically: The sealing assembly 42 includes a sealing seat 421 and a sealing plate 422. The sealing seat 421 has a slot extending through the sealing seat 421 in the horizontal direction in the middle thereof. The sealing seat 421 has two through holes a4211 and b4212 extending through the sealing seat 421 in the horizontal direction and communicating with the slot. The sealing seat 421 is fixedly mounted on the end face of the storage box, and the two through holes on the sealing seat 421 are respectively matched and docked with the two mud inlets 412 or mud outlets 413 on the same end face of the storage box. The sealing plate 422 is matched and inserted into the slot and is connected to the push-pull mechanism 43. The sealing plate 422 is axially spaced with connecting holes a4221 and b4222. When the sealing plate 422 is driven to slide by the push-pull mechanism 43 to overlap the connecting holes, the through hole is opened. The discharge port of the separation barrel 31 is matched and connected with a Y-shaped three-way joint. The two discharge ends of the three-way joint are downwardly arranged and respectively connected to the through hole a4211 and the through hole a4211 of the sealing seat 421 on the upper side of the storage box.

[0033] The push-pull mechanism 43 includes a mounting platform 431 arranged on the upper side of the cleaning boat 1 on the right side of the temporary storage box 41, and an electric push rod 432 is vertically installed on the mounting platform 431. The telescopic end of the electric push rod 432 is arranged toward the temporary storage box 41, and a connecting frame 433 is installed. The upper and lower ends of the connecting frame 433 are respectively matched and inserted into the slots of the sealing seat 421 of the sealing assembly 42 on the same side, and are connected to the ends of the sealing plate 422. When the electric push rod 432 drives the connecting frame 433 to move left and right, it will drive the sealing plates 422 in the two sealing assemblies 42 to move left and right in the corresponding sealing seats 421 synchronously.

[0034] like Figure 6 As shown, when in use, when the connecting hole b4222 on the upper sealing plate 422 overlaps with the through hole b4212 of the upper sealing seat 421, the upper sealing plate 422 blocks the through hole a4211 of the upper sealing seat 421, and the connecting hole a4221 on the upper sealing plate is located on the left side of the through hole a4211 of the upper sealing seat 421. In this state, the connecting hole a4221 on the lower sealing plate 422 of the storage box overlaps with the through hole a4211 of the lower sealing seat 421, the lower sealing plate 422 blocks the through hole b4212 of the lower sealing seat 421, and the connecting hole b4222 on the lower sealing plate is located on the left side of the through hole b4212 of the lower sealing seat 421.

[0035] The push-pull mechanism 43 can synchronously control the mud inlet 412 and the mud discharge port 413 at the upper and lower ends of the two storage chambers 411 to open and close alternately through the two sealing hole components 42, and the mud inlet 412 and the mud discharge port 413 of the two storage chambers 411 are opened and closed alternately, that is, when the mud discharge port 413 of the left storage chamber 411 is closed and the mud inlet 412 is opened, the mud discharge port 413 of the right storage chamber 411 is opened and the mud inlet 412 is closed; when in use, when the mud and sand particles in the storage chamber 411 on one side are full, the mud inlet 412 of the storage chamber 411 is closed and the mud discharge port 413 is opened for discharge, and the mud discharge port 413 of the other storage chamber 411 is closed and the mud inlet 412 is opened for alternate storage and discharge, thereby improving the cleaning efficiency of the riverbed mud. The transfer device 5 is arranged on the cleaning ship 1 below the two mud discharge ports 413 of the temporary storage box 41.

[0036] This embodiment provides an integrated sediment separation pump station. When in use, first, drive the cleaning ship 1 to the predetermined river operation area, and adjust the sediment extraction device 2 at the stern to lower it to the river bottom. Start the centrifugal pump of the sediment treatment unit of the pump station, and the negative pressure generated by the pump draws the riverbed sediment into the separation barrel 31 through a series of pipelines; the sediment mixture enters the separation barrel 31 through the tangentially arranged mud extraction pipe 32, forming a rotating water flow in the barrel. Under the action of centrifugal force, the sediment particles are thrown to the barrel wall and fall along the wall, and are finally discharged from the discharge port at the bottom of the barrel and enter the temporary storage box 41 of the alternating discharge device 4 below. The separated water is pumped out and discharged through the vertically arranged water extraction pipe 33.

[0037] Two independent storage chambers 411 are provided in the temporary storage box 41. The push-pull mechanism 43 synchronously adjusts the opening and closing of the inlet and outlet of the two storage chambers 411 by controlling the two sets of sealing components 42. When the mud inlet 412 of the left storage chamber 411 is opened and the mud outlet 413 is closed, the mud and sand are continuously filled into the left chamber; at the same time, the mud inlet 412 of the right storage chamber 411 is closed and the mud outlet 413 is opened to discharge the stored mud and sand. When the left storage chamber 411 is full, the push-pull mechanism 43 switches the sealing hole to start draining, and the right storage chamber 411 starts filling. In this way, continuous and uninterrupted mud and sand discharge is achieved. The discharged mud and sand are transported to the mud and sand storage bin 11 on the ship by the transfer device 5 arranged under the temporary storage box 41. When the storage bin 11 is full, the cleaning ship 1 is driven to the designated mud and sand unloading point, and the mud and sand are unloaded to the shore by the unloading equipment, and then transported to the designated location for centralized disposal or resource utilization. Example

[0038] The difference between Example 2 and Example 1 is that the transfer device 5 is arranged on the cleaning ship 1 below the two mud outlets 413 of the temporary storage box 41, and the transfer device 5 includes two belt conveyors 51 arranged at a lateral interval, one end of the two belt conveyors 51 is respectively located below the mud outlets 413 of the two storage chambers 411, and the other ends of the two belt conveyors 51 extend into the mud storage bin 11, so as to transport the mud particles discharged through the mud outlets 413 to the mud storage bin 11. Example

[0039] The difference between Example 3 and Example 2 is that the discharge end of the centrifugal pump is connected to a secondary treatment pool, a drain port is provided on the side wall in the middle of the secondary treatment pool, and is connected to a drain pipe. During use, larger silt particles injected into the water of the secondary treatment pool will automatically sink to the bottom of the pool, and an air pipe is provided in the pool below the drain port of the secondary treatment pool. The air pipe is connected to an air supply device for discharging high-pressure air into the air pipe, and exhaust holes are evenly distributed on the air pipe. During use, air discharged through the exhaust holes of the air pipe will form bubbles in the secondary treatment pool and automatically float to the water surface. In the process of the bubbles floating to the water surface, the bubble body of the bubble will absorb the fine silt particles in the water, causing them to float to the water surface together with the bubbles, thereby further reducing the suspended matter content in the middle layer of water, so that it can be directly discharged back into the river water through the drainage section.
