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 uses the sediment separation equipment for treatment.

[0003] The existing river channel cleaning sediment separation pump station is set on one side of the river channel and cannot 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 and then transport it to the shore. The river channel cleaning sediment separation pump station is then used to treat the liquid containing sediment particles extracted by the suction dredger. The functions are scattered, which is not only costly, but also requires the suction dredger to carry the riverbed sediment back and forth, resulting in poor continuous operation capacity, low efficiency, lack of integration and optimization, and poor maneuverability. In addition, when the existing river channel 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

[0028] The present invention will be further described below with reference to the accompanying drawings and examples. Example

[0029] The embodiment provides an integrated sediment separation pump station with a unique structure and ingenious design. Figure 1-7 As shown, it includes a cleaning ship 1, a sediment processing 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 processing 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 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 pumping pipe 32 is tangentially provided on one side of the upper section of the separation barrel 31 and is connected to its interior. The other end of the mud pumping 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:

[0030] A hanger 12 is provided on the rear side of the cleaning ship 1, and the hanger 12 is fixedly connected to the cleaning ship 1. The sediment extraction device 2 is installed in the hanger 12 along the vertical sliding direction and is connected to the lifting drive assembly 24. The height of the sediment extraction device 2 immersed in the water can be controlled by the lifting drive assembly 24. The sediment 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 for controlling 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 provided vertically 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. When the winch device releases the traction rope, the outer frame 211 will rely on its own weight to descend along the hanger 12.

[0031] The top end of the scattering tube 215 is rotatably installed in the outer frame 211 and is transmission-connected to the rotary drive assembly 24. Specifically, a fixed sleeve 212 is vertically provided in the outer frame 211, and a plurality of fixed rods 213 are evenly spaced along the circumference on the outer ring surface of the fixed sleeve 212. The other end of the fixed 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 fixed sleeve 212 through a bearing 25, and a scattering tooth 216 is provided on the outer ring surface of the bottom end of the scattering tube 215.

[0032] 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 fitted with a drive gear. A fixed sleeve 212 on the scattering tube 215 below the outer frame 211 is fitted with a driven gear, and the driven gear and the drive gear are connected via a chain transmission.

[0033] 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 suction pipe 33. 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 at intervals along the outer edge of the water suction pipe 33, and the shaft sleeves 26 are matched and rotatably mounted in the scattering pipe 215. When in use, after the sediment extraction device 2 is lowered to the river bottom, the centrifugal pump is turned on, and negative pressure is generated in the separation barrel 31. The river bottom sediment is sucked into the separation barrel 31 through the mud suction pipe 32, the mud suction hose 34 and the sediment extraction device 2. Since the water suction pipe 33 is arranged tangentially along the separation barrel 31, the river water mixed with sediment will be in the separation barrel 3 after entering the separation barrel 31 through the water suction pipe 33. 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 extracted and discharged through the suction pipe 33 by the centrifugal pump. When in use, the centrifugal pump is used as a power source to draw the riverbed silt into the separation barrel 31 to separate the silt particles, and the separated liquid is extracted. When the liquid is extracted 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 up the deposited silt, thereby facilitating suction.

[0034] 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 provided 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 a mud inlet 412 and a mud outlet 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 upper and lower ends of the temporary storage box 41 are both equipped with sealing assemblies 42, and the sealing assembly 42 is transmission-connected to the push-pull mechanism 43. The push-pull mechanism 43 can synchronously control the mud inlet 412 and the mud outlet 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 inlet 412 of the two storage chambers 411 and the mud outlet 413 of the two storage chambers 411 are alternately opened and closed. Specifically:

[0035] The sealing assembly 42 includes a sealing seat 421 and a sealing plate 422. The middle part of the sealing seat 421 is provided with a slot that penetrates the sealing seat 421 in the horizontal direction. The sealing seat 421 is provided with two through holes a4211 and b4212 that penetrate the sealing seat 421 in the vertical direction and communicate 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 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 connecting holes 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, and the two discharge ends of the three-way joint are set downward 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.

[0036] 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 set toward the temporary storage box 41 and is installed with a connecting frame 433. 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 component 42 on the same side, and are connected to the end 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 components 42 to move left and right synchronously in the corresponding sealing seats 421.

[0037] like Figure 6 As shown, during 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.

[0038] The mud inlet 412 of the left storage chamber 411 is closed and the mud outlet 413 of the right storage chamber 411 is opened, and the mud inlet 412 of the left storage chamber 411 is opened. When the mud inlet 412 is closed, the mud outlet 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 outlet 413 is opened for discharge. The mud outlet 413 of the other storage chamber 411 is closed and the mud inlet 412 is opened for alternating 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 outlets 413 of the temporary storage box 41.

[0039] This embodiment provides an integrated sediment separation pump station. When in use, first, drive the cleaning ship 1 to the predetermined river operation area, adjust the sediment extraction device 2 at the stern of the ship, and lower it to the riverbed. Start the centrifugal pump of the sediment treatment unit of the pump station. 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.

[0040] The temporary storage box 41 contains two independent storage chambers 411 on the left and right. A push-pull mechanism 43 controls the opening and closing of the inlets and outlets of the two storage chambers 411 by controlling two sets of sealing assemblies 42. When the mud inlet 412 of the left storage chamber 411 is open and the mud outlet 413 is closed, mud and sand continuously fill into the left chamber. Simultaneously, the mud inlet 412 of the right storage chamber 411 is closed and the mud outlet 413 is opened, allowing the stored mud and sand to be discharged. When the left storage chamber 411 is full, the push-pull mechanism 43 switches the sealing mechanism, allowing it to begin draining, while the right storage chamber 411 begins filling. This alternating process ensures continuous and uninterrupted mud and sand discharge. The discharged mud and sand are transferred to the ship's mud storage bin 11 via a transfer device 5 located below the temporary storage box 41. Once the bin 11 is full, the cleaning vessel 1 is driven to a designated mud unloading point, where the mud and sand are unloaded onto shore using unloading equipment. The unloading equipment then transports the mud and sand to a designated location for centralized disposal or resource recovery. Example

[0041] 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 along the horizontal interval, and 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, for transporting the mud particles discharged through the mud outlet 413 to the mud storage bin 11. Example

[0042] 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 outlet is provided on the side wall in the middle of the secondary treatment pool, and is connected to a drain pipe. During use, larger sediment 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 outlet of the secondary treatment pool. The air pipe is connected to an air supply device for discharging high-pressure air into the air pipe. Exhaust holes are evenly distributed on the air pipe. During use, the 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 sediment particles in the water, causing them to float to the water surface along 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.
