Description

Technical Field

[0001] This utility model relates to the field of fluid transport equipment technology, and more specifically, to a shore-based pump. Background Technology

[0002] Shore-based pumps are mainly used in various water-based operations, especially in industrial or construction projects near oceans, lakes, rivers, and other bodies of water. Shore-based pumps can lift liquids at higher flow rates and pressures, greatly improving transport efficiency, reducing energy consumption, and ensuring efficient, safe, and environmentally friendly transport of liquids.

[0003] In the context of brine transportation in salt fields, shore-based pumps connect the salt fields and processing plants, continuously delivering brine to the processing workshops. Traditionally, shore-based pumps are installed on salt field embankments, with the pump base constructed using concrete. However, due to the unique environment of salt fields, the soil of the embankments, which serve as the foundation for shore-based pumps, has a very high salt content. Even a slight brine leak can erode the salt crust, weakening the embankment structure and potentially leading to dam failure. Furthermore, brine leaking to the surface dissolves salts in the embankment soil, creating a highly corrosive mixture that gradually erodes the concrete base, reducing the safety and reliability of the shore-based pump and shortening its lifespan. Utility Model Content

[0004] The main purpose of this utility model is to provide a shore-based pump that can solve the problem that when existing shore-based pumps are installed in salt field dams, brine leakage to the ground weakens the dam structure and corrodes the cement base, resulting in reduced safety and reliability of the shore-based pump and shortened service life.

[0005] To achieve the above objectives, according to one aspect of the present invention, a shore-based pump is provided, comprising a pump body and a flow guide seat. The flow guide seat includes a flow guide plate and side plates located around the flow guide plate. The pump body is disposed on the flow guide plate. The vertical projection of the pipe connection of the pump body is located within the flow guide seat. A drain pipe is disposed on the side plate, and the drain pipe connects to the flow guide seat and extends outward to a safe area.

[0006] Furthermore, the guide plate is tilted to one side, and the drain pipe is set on the side plate located on the lowest side of the guide plate, with the guide plate's flow direction pointing towards the drain pipe.

[0007] Furthermore, a horizontal filter plate is installed above the guide plate, with through holes on the filter plate. The pump body passes through the through holes and extends outwards. The filter plate is also equipped with filter holes.

[0008] Furthermore, the flow guide seat also includes a base plate, with two flow guide plates disposed opposite each other on the base plate and inclined inward to form a V-shaped flow guide plate.

[0009] Furthermore, bolts are provided on the base plate, which can extend outwards to secure the base plate.

[0010] Furthermore, a liquid level sensor and a leakage recovery pump are installed inside the flow guide seat. The liquid level sensor can detect the liquid level inside the flow guide seat, and the leakage recovery pump is located on the lowest side of the flow guide plate.

[0011] Furthermore, a mounting base is provided between the pump body and the guide plate. The mounting base is fixedly mounted on the guide plate, and the pump body and the mounting base are detachably connected.

[0012] Furthermore, the mounting base includes a channel steel and a pump base mounted on the channel steel. The channel steel is welded to the guide plate, the channel steel is bolted to the pump base, and the pump base is bolted to the pump body.

[0013] Furthermore, the angle of the guide plate relative to the horizontal plane is 3°~5°.

[0014] Furthermore, the height of the side plate is 15cm to 20cm.

[0015] Applying the technical solution of this utility model, the pump body is responsible for lifting liquids such as carnallite slurry from the collection point to a sufficient height so that they can be transported to the processing workshop through the conveying pipeline. It is typically driven by a motor, generating the pumping action through the rotation of an impeller. The guide seat, as the supporting structure of the pump body, not only provides a stable installation foundation for the pump body but also, by setting a base plate inside, changes the flow direction of leaking brine slurry around the pump, helping to guide the brine to be discharged or recycled. The vertical projection of the pipe connection between the conveying pipeline and the pump body is located within the guide seat, ensuring that any possible leaks during the extraction and transportation of the brine slurry are within the catchment area of ​​the guide seat. Side plates are arranged around the guide plate, forming a closed guide seat space to prevent lateral overflow of brine. A drain pipe is used to discharge brine slurry leaking from the pump body and conveying pipeline into the guide seat to a safe area away from the salt field dam, preventing leaks from reaching the surface.

[0016] The shore-based pump proposed in this utility model ensures that any leaks or spills during the transportation of brine slurry fall into the guide seat, rather than leaking directly to the surface and eroding the salt field dam, thus weakening or even causing the dam structure to collapse. This improves the safety and reliability of the shore-based pump and extends its service life. Attached Figure Description

[0025] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] See also Figures 1 to 5 As shown, this utility model provides a shore-based pump, which includes a pump body 1, a delivery pipe 11, and a flow guide seat 2. The flow guide seat 2 includes a base plate 3 and side plates 21 located around the base plate 3. The pump body 1 is mounted on the base plate 3. The delivery pipe 11 is connected to the pump body 1. The vertical projection of the pipe connection between the delivery pipe 11 and the pump body 1 is located within the flow guide seat 2. A drain pipe 4 is provided on the side plate 21. The drain pipe 4 connects to the flow guide seat 2 and extends outward to a safe area.

[0027] In the above technical solution, the pump body 1 is responsible for lifting the carnallite slurry and other liquids from the collection point to a sufficient height so that they can be transported to the processing workshop through the conveying pipe 11. It is usually driven by a motor, and the pumping action is generated by the rotation of the impeller. The guide seat 2, as the supporting structure of the pump body, not only provides a stable installation foundation for the pump body, but also changes the flow direction of the leaking brine slurry around the pump by setting a base plate 3 inside, which helps to guide the brine to be discharged or recycled. The projection of the pipe connection between the conveying pipe 11 and the pump body 1 is located inside the guide seat 2, ensuring that all possible leaks of brine slurry during extraction and transportation are within the containment range of the guide seat 2. The side plate 21 is arranged around the guide plate to form a closed guide seat space, preventing the brine from overflowing laterally. The drain pipe 4 is used to discharge the brine slurry leaking into the guide seat 2 from the pump body 1 and the conveying pipe to a safe area away from the salt field dam, preventing the leaked liquid from leaking to the ground.

[0028] The shore-based pump proposed in this utility model ensures that any leaks or spills during the transportation of brine slurry can drip into the guide seat 2, rather than directly leaking to the surface and eroding the salt field dam, thus weakening or even causing the dam structure to collapse. This improves the safety and reliability of the shore-based pump and extends its service life.

[0029] In one embodiment of this utility model, the base plate 3 is tilted to one side, and the drain pipe 4 is disposed on the side plate 21 located on the lowest side of the base plate 3, with the flow direction of the base plate 3 pointing towards the drain pipe 4.

[0030] In the above technical solution, the base plate 3 is tilted to one side, which effectively guides the liquid to gather towards the lower side under gravity. Especially when processing brine containing solid particles, this prevents solids from depositing on the guide plate and reduces the risk of brine crystallization on the guide plate. The drain pipe 4 is located on the side plate 21 at the lowest side of the base plate 3, ensuring that leaked liquid collected by the guide seat 2 can be fully discharged through the drain pipe 4, avoiding prolonged liquid stagnation in the guide seat and causing corrosion. The base plate 3 guides the brine to the drain pipe 4, preventing liquid stagnation in the guide seat and minimizing the corrosive damage of the brine slurry to the pump body 1 and the guide seat 2. By tilting the base plate 3 and optimizing the position of the drain pipe 4, the brine flow direction can be effectively controlled, drainage efficiency can be improved, equipment maintenance frequency can be reduced, and equipment life can be extended.

[0031] In one embodiment of this utility model, the slope of the base plate 3 relative to the horizontal plane is 3°~5°.

[0032] In the above technical solution, whether it is a slight leak or a sudden excessive leak, the 3°~5° inclination can ensure that the brine can be effectively guided to the drain pipe 4, reduce the residue on the bottom plate 3, ensure the smooth flow of the brine, and thus improve the diversion efficiency.

[0033] In one embodiment of this utility model, a horizontal filter plate 5 is also provided above the base plate 3, the pump body 1 is provided on the base plate 3, the filter plate 5 is provided with a through hole, the pump body 1 passes through the through hole and extends outward, the filter plate 5 is provided with filter holes, and multiple filter holes are evenly distributed on the filter plate 5.

[0034] In the above technical solution, the filter plate 5 is located above the base plate 3, serving to filter and separate solid particles in the brine. The pump body 1 passes through the through hole and extends outward, so that the filter plate 5 surrounds the pump body 1, ensuring that any leakage from the pump body 1 and the pipe connection can first drip onto the filter plate 5 for filtration. The filter holes on the filter plate 5 ensure that the brine can pass through smoothly, while larger particles of impurities are intercepted, thereby reducing the probability of blockage or wear of the drain pipe 4, thus shortening the maintenance frequency and extending the service life of the drain pipe 4.

[0035] In one embodiment of the present invention, the flow guide seat 2 further includes a flow guide plate 22, and two flow guide plates 22 are disposed opposite to each other on the base plate 3 and inclined inward to form a V-shaped flow guide plate.

[0036] In the above technical solution, the base plate 3 serves as the foundation of the guide seat 2, and is placed horizontally on the salt field embankment, providing a solid support surface for the entire shore-based pump. It also evenly distributes the weight of the pump body 1 and its operational vibrations, significantly enhancing the pump's stability and service life compared to an inclined base plate 3. Two guide plates 22 are positioned opposite each other on the base plate 3 and tilt inwards to form a V-shaped guide plate, shortening the distance the dripping brine travels to the drain pipe. Simultaneously, the V-shaped guide plate has a greater inclination, increasing the flow velocity of the dripping brine under gravity, thereby improving the efficiency of the dripping brine's collection and discharge.

[0037] In one embodiment of this utility model, when two guide plates 22 are arranged opposite to each other on the base plate 3 and tilted inward to form a V-shaped guide plate, bolts are provided on the base plate 3, and the bolts can extend outward to fix the base plate 3.

[0038] In the above technical solution, the bolts can firmly anchor the base plate 3 to the ground of the salt field embankment or shoreline, ensuring that the pump body 1 and the guide seat 2 will not shift or overturn even under severe natural conditions such as strong winds or earthquakes. Meanwhile, compared to the solution of placing the inclined base plate 3 directly on the salt field embankment without a guide plate 22, if bolts are used to pass through the base plate 3 and directly fix it to the embankment, holes need to be drilled in the base plate 3. This reduces the sealing performance of the base plate 3, potentially causing the dripping brine to leak through the holes onto the ground of the salt field embankment or shoreline during its flow. This cannot effectively prevent the dripping brine from eroding the salt cover and weakening the embankment structure. Therefore, a V-shaped guide plate is installed on the base plate 3 and the base plate 3 is firmly anchored to the ground of the salt field embankment or shoreline with bolts. This ensures that the pump body 1 and the guide seat 2 will not shift or overturn under natural conditions, while also ensuring the sealing of the base plate 3 to prevent brine from leaking through the opening and causing damage to the salt field embankment.

[0039] In one embodiment of this utility model, a liquid level sensor 23 and a leakage recovery pump 24 are provided inside the flow guide seat 2. The liquid level sensor 23 can detect the liquid level inside the flow guide seat 2, and the leakage recovery pump 24 is located on the lowest side of the base plate 3.

[0040] In the above technical solution, the liquid level sensor 23 can monitor the liquid level in the guide seat 2 in real time. When the drain pipe 4 is blocked, or the main delivery pump pipeline is damaged, resulting in a large amount of brine leakage, the brine accumulation rate in the guide seat 2 is greater than the drainage rate of the drain pipe, causing the brine level in the guide seat 2 to rise rapidly. There is a risk that the brine will overflow from the side plate 21 to the salt field dam. At this time, the liquid level sensor 23 monitors the brine level. When the leaked brine in the guide seat 2 reaches the dangerous liquid level, the liquid level sensor 23 can control the start of the leakage recovery pump 24 to recover the leaked brine in the guide seat 2, thereby reducing the brine level in the guide seat 2. At the same time, it can also issue an alarm signal to remind the operator, thereby eliminating or mitigating the risk of brine overflowing from the side plate 21 to the salt field dam. The leakage recovery pump 24 is set on the lowest side of the base plate 3 to ensure that the leakage recovery pump 24 can fully extract the brine in the guide seat 2, improving the brine extraction efficiency and effect.

[0041] In one embodiment of this utility model, a mounting base 6 is also provided between the pump body 1 and the base plate 3. The mounting base 6 is fixedly mounted on the base plate 3, and the pump body 1 and the mounting base 6 are detachably connected.

[0042] In the above technical solution, the mounting base 6 serves as a connecting bridge between the pump body 1 and the base plate 3. It ensures the stability and positioning accuracy of the pump body 1 during operation, while also providing necessary support. Through its fixed connection with the base plate 3, the mounting base 6 can withstand the vibration and load of the pump body 1 during operation, preventing wear caused by direct contact between the pump body 1 and the base plate 3. The detachable connection between the pump body 1 and the mounting base 6 makes replacement or maintenance of the pump body 1 more convenient. This design allows for individual maintenance or upgrades of the pump body 1 without removing the entire shore-based pump frame or filter plate, thereby reducing the impact of maintenance work on the production process.

[0043] In one embodiment of the present invention, the mounting base 6 includes a channel steel 61 and a pump base 62 disposed on the channel steel 61. The channel steel 61 is welded to the base plate 3, the channel steel 61 is bolted to the pump base 62, and the pump base 62 is bolted to the pump body 1.

[0044] In the above technical solution, channel steel, as a common structural steel material, possesses excellent bending resistance and stability when bearing lateral loads due to its C-shaped opening. In this embodiment, channel steel 61 mainly serves as the foundation component of mounting base 6. By welding it to the base plate 3, it increases the rigidity and load-bearing capacity of the entire system, while providing stable support for the pump base 62. The welding connection between channel steel 61 and base plate 3 creates a robust bond, reducing vibration or noise caused by loose connections and ensuring reliable equipment operation.

[0045] In one embodiment of this utility model, the height of the side plate 21 is 15cm to 20cm.

[0046] In the above technical solution, the higher side plate 21 can form an effective barrier, which can prevent brine from overflowing the guide seat 2 when the pump body 1 or the conveying pipeline leaks, thereby avoiding the erosion of the dam structure and the potential risk of dam failure caused by the overflow of brine.

[0047] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The pump body 1 is responsible for lifting liquids such as carnallite slurry from the collection point to a sufficient height so that they can be transported to the processing workshop through the conveying pipe 11. It is usually driven by a motor, and the pumping action is generated by the rotation of the impeller. The guide seat 2, as the supporting structure of the pump body, not only provides a stable installation foundation for the pump body, but also changes the flow direction of the leaking brine slurry around the pump by setting a base plate 3 inside, which helps to guide the brine to be discharged or recycled. The projection of the pipe connection between the conveying pipe 11 and the pump body 1 is located inside the guide seat 2, ensuring that all possible leaks during the extraction and transportation of brine slurry are within the receiving range of the guide seat 2. The side plate 21 is arranged around the guide plate to form a closed guide seat space, preventing the brine from overflowing laterally. The drain pipe 4 is used to discharge the brine slurry leaking into the guide seat 2 from the pump body 1 and the conveying pipe to a safe area away from the salt field dam, avoiding the leakage of liquid to the ground.

[0048] The shore-based pump proposed in this utility model ensures that any leaks or spills during the transportation of brine slurry can drip into the guide seat 2, rather than directly leaking to the surface and eroding the salt field dam, thus weakening or even causing the dam structure to collapse. This improves the safety and reliability of the shore-based pump and extends its service life.
