Description

Technical Field

[0001] This invention relates to the field of sedimentation in water tanks, and more particularly to a sedimentation device and method for an open circulating water tank. Background Technology

[0002] Settling in an open circulating water tank refers to the process by which suspended sediment particles in the water settle to the bottom of the tank through the action of water flow. In existing technologies, sediment from the environment is introduced into the tank and then blown around by the circulating water, which cannot achieve a good sedimentation effect. During this process, the sediment particles are eventually sucked into the circulating water pump by the suction force of the circulating water pump, and finally enter the cooling equipment through the circulating water pump pipes, causing scale or even blockage in the heat exchange equipment, thus affecting the heat exchange effect. Summary of the Invention

[0003] This invention overcomes the shortcomings of the prior art and provides an open circulating water tank sedimentation device and sedimentation method thereof.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an open circulating water tank sedimentation device, comprising: a water storage tank and several circulating walls disposed in the middle of the water storage tank.

[0005] The reservoir contains several circulation pools, with the bottom of each pool inclined. The circulation walls are fixedly connected to the reservoir, thus dividing the reservoir into several circulation pools.

[0006] The circulating wall is equipped with a circulation component for water circulation, and an interception net for intercepting floating objects is installed above the circulating wall. Circulation holes are opened on the circulating wall.

[0007] The circulation components include M-shaped tubes and L-shaped tubes, which are respectively located above and below the two sides of the circulation wall.

[0008] In a preferred embodiment of the present invention, the circulating wall includes a first wall, a second wall, and a third wall, and the circulating wall is arranged in a T-shape.

[0009] In a preferred embodiment of the present invention, the circulation pool is divided into a first pool, a second pool, and a third pool, and the circulation wall is fixedly connected to the middle of the circulation pool, thereby separating the circulation pool into three independent pools.

[0010] In a preferred embodiment of the present invention, a first wall is disposed between a first water tank and a second water tank, a second wall is disposed between a first water tank and a second water tank, and a third wall is disposed between a second water tank and a third water tank.

[0011] In a preferred embodiment of the present invention, the circulation component includes a water storage chamber, an M-shaped pipe and an L-shaped pipe disposed on both sides of the water storage chamber; the circulation component is provided in both the second wall and the third wall.

[0012] In a preferred embodiment of the present invention, the M-shaped tube and the L-shaped tube are respectively disposed in the circulation pools on both sides of the circulation wall, and the interception net is disposed below the M-shaped tube, with the aperture of the interception net being 1*1cm.

[0013] In a preferred embodiment of the present invention, circulation holes are provided below the second wall and the third wall, and the circulation holes are located 50cm away from the bottom of the circulation pool.

[0014] In a preferred embodiment of the present invention, a circulating water pump is provided at the bottom of the third water tank, and the position of the circulating water pump is lower than the height of the circulation hole.

[0015] A method for sediment settling in an open circulating water tank includes the following steps:

[0016] S1: Add mud and water to the circulation tank. Since the bottom of the circulation tank is set at an angle, the mud and sand in the mud and water will be deposited at the bottom of the circulation tank due to gravity. Also, since the bottom of the circulation tank is set at an angle, the mud and sand will accumulate together along the angled bottom of the circulation tank.

[0017] S2: As the sludge is added to the bottom of the circulation tank, the water level gradually rises until it reaches the circulation hole, allowing the sludge to enter other circulation tanks for sedimentation and filtration.

[0018] S3: As mud and water are continuously added, the mud and water level gradually rises because the amount of mud and water added is greater than the water output of the circulation hole. As the mud and water rise, sedimentation occurs, and the mud and water rises to the circulation component; it then undergoes filtration again through the circulation component.

[0019] In a preferred embodiment of the present invention, in S3, the M-shaped pipe and L-shaped pipe of the circulation component are respectively arranged in the circulation pools on both sides of the circulation wall. The M-shaped pipe is arranged above the circulation pool, and the L-shaped pipe is arranged below the circulation pool. The muddy water enters the water storage chamber from the circulation pool through the M-shaped pipe, and then enters the circulation pool on the other side from the water storage chamber through the L-shaped pipe, thereby forming a siphon effect.

[0020] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0021] (1) The present invention is an open circulating water tank sedimentation device and sedimentation method. Through the cooperation of the circulating tank, the circulating wall and the circulating components, mud and water are introduced into the circulating tank. As the water level in the circulating tank rises, the circulating components on the circulating wall generate a siphon effect. The mud and water undergo multiple cycles of sedimentation and filtration through the circulating wall and the circulating components, thereby improving the filtration efficiency of the mud and water. The floating objects in the mud and water are intercepted by the interception net, thereby improving the filtration efficiency.

[0022] (2) The present invention is an open circulating water tank sedimentation device and sedimentation method. Through the cooperation of the circulation component, the interception net and the circulation tank, after the mud and water enter the circulation tank, the mud and water will settle due to gravity, so that the silt and debris in the mud and water will be separated from the water. As the water level rises, the circulation component will have a siphon effect. At the same time, the interception net will intercept the floating objects below the circulation component, effectively preventing the circulation component from sucking the floating objects to the next circulation tank. Thus, the upper part of the mud and water that has been separated will be sucked into the next circulation tank for further sedimentation, thereby achieving the effect of circulating sedimentation and filtration and preventing clogging.

[0023] (3) The present invention is an open circulating water tank sedimentation device and sedimentation method. Through the cooperation between the circulation hole, circulation component and circulation tank, the mud and water are initially filtered through the circulation hole as the water level rises. At the same time, the silt and debris in the mud and water are effectively prevented from entering the upper part of the device. Then, the mud and water are extracted again through the siphon effect of the circulation component and extracted to the next circulation tank. By performing sedimentation filtration and purification twice in each circulation tank, the filtration efficiency and purity are effectively improved. At the same time, the mud and sand are effectively prevented from entering the circulating water pump and clogging the heat exchange equipment. Attached Figure Description

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, an open-type circulating water tank sedimentation device includes: a water storage tank 1 and several circulating walls 2 disposed in the middle of the water storage tank 1.

[0034] It should be noted that the circulating wall 2 is fixedly connected to the middle of the water storage tank 1. The circulating wall 2 is T-shaped, thus dividing the water storage tank 1 into three parts.

[0035] The water storage tank 1 is equipped with several circulation tanks. The bottom of the circulation tank is set in an inclined shape. The circulation wall 2 is fixedly connected to the water storage tank 1, thereby dividing the water storage tank 1 into several circulation tanks.

[0036] In a preferred embodiment of the present invention, the circulating wall 2 includes a first wall 3, a second wall 4, and the circulating wall 2 is arranged in a T-shape.

[0037] In a preferred embodiment of the present invention, the circulation pool is divided into a first pool 6, a second pool 7 and a third pool 8, and the circulation wall 2 is fixedly connected to the middle of the circulation pool, thereby separating the circulation pool into three independent pools.

[0038] In a preferred embodiment of the present invention, the first wall 3 is disposed between the first water tank 6 and the second water tank 7, the second wall 4 is disposed between the first water tank 6 and the second water tank 7, and the third wall 5 is disposed between the second water tank 7 and the third water tank 8.

[0039] It should be noted that the circulating wall 2 consists of a first wall 3, a second wall 4, and a third wall 5. The first wall 3, second wall 4, and third wall 5 are arranged in a T-shape, with one end of each wall connected to the same fixed point. The first wall 3 and third wall 5 are arranged side-by-side, and the second wall 4 is perpendicular to the connection point of the first wall 3 and third wall 5. The other ends of the first wall 3, second wall 4, and third wall 5 are fixedly connected to the side of the water storage tank 1, dividing the water storage tank 1 into three circulating pools for filtration: a first pool 6, a second pool 7, and a third pool 8. The first pool 6 and second pool 7 are respectively located on either side of the second wall 4, and the third pool 8 is located on the side of the first wall 6. On one side of wall 3, i.e. the side away from the second wall 4, the bottom of each circulation pool is set in an inclined shape. In the first pool 6, the depth of the first pool 6 gradually decreases along the vertical direction of the first wall 3, i.e., the depth of the bottom of the first pool 6 gradually decreases as it moves away from the first wall 3. In the second pool 7, the bottom of the second pool 7 gradually increases along the vertical direction of the second wall 4, i.e., the depth of the second pool 7 gradually increases as it moves away from the second wall 4. In the third pool 8, the depth of the third pool 8 gradually decreases along the vertical direction of the plane where the third wall 5 is located, i.e., the depth of the third pool 8 gradually decreases as it moves away from the plane where the third wall 5 is located.

[0040] The circulating wall 2 is equipped with a circulating component for water circulation, and the circulating wall 2 is equipped with an interception net 9 for intercepting floating objects. The circulating wall 2 is provided with circulation holes 12.

[0041] The circulation component includes an M-shaped tube 10 and an L-shaped tube 11, which are respectively located above and below the two sides of the circulation wall 2.

[0042] In a preferred embodiment of the present invention, the circulation component includes a water storage cavity, an M-shaped pipe 10 and an L-shaped pipe 11 disposed on both sides of the water storage cavity; the second wall 4 and the third wall 5 are both provided with circulation components.

[0043] In a preferred embodiment of the present invention, M-shaped tube 10 and L-shaped tube 11 are respectively disposed in the circulation pools on both sides of the circulation wall 2, and the interception net 9 is disposed below the M-shaped tube 10, with the aperture of the interception net 9 being 1*1cm.

[0044] In a preferred embodiment of the present invention, circulation holes 12 are provided below the second wall 4 and the third wall 5, and the circulation holes 12 are located 50cm away from the bottom of the circulation pool.

[0045] In a preferred embodiment of the present invention, a circulating water pump is provided at the bottom of the third water tank 8, and the position of the circulating water pump is lower than the height of the circulation hole 12.

[0046] It should be noted that circulation components are provided in both the second wall 4 and the third wall 5. These components include a water storage chamber, an M-shaped pipe 10, and an L-shaped pipe 11. The water storage chambers are respectively located between the first wall 3, the second wall 4, and the third wall 5, i.e., within the second wall 4 and the third wall 5. The M-shaped pipe 10 and the L-shaped pipe 11 are respectively located on both sides of the water storage chamber. The horizontal position of the M-shaped pipe 10 is higher than that of the L-shaped pipe 11. The M-shaped pipe 10 is M-shaped with two peaks, the two peaks being at different horizontal heights, with the first peak at a lower horizontal plane than the second peak. On the horizontal plane, both the M-shaped pipe 10 and the L-shaped pipe 11 penetrate the water storage cavity, i.e., they penetrate the second wall 4 or the third wall 5. The position of the M-shaped pipe 10 is always higher than that of the L-shaped pipe 11. The M-shaped pipe 10 has four points: the front end, the rear end, the first peak near the front end, and the second peak. In the second wall 4, the front end, the first peak, and the second peak of the M-shaped pipe 10 are all located in the first water tank 6. The second peak is close to the second wall 4. The second peak penetrates the second wall 4 at the middle of its rear end and is fixedly connected to the second wall 4. The latter half of the L-shaped pipe 11 is located in the water storage cavity within the second wall 4. The L-shaped pipe 11 has three points: the front end, the rear end, and the bend end of the middle section. The bend end is closer to the front end than to the rear end. The front end and the bend end are located in the water storage cavity within the second wall 4. The bend end is close to the wall of the second wall 4. The first half of the pipe from the bend end to the rear end penetrates both walls, while the second half is located in the second water tank 7. The structure and placement of the M-shaped pipe 10 and L-shaped pipe 11 on the second wall 4 and the third wall 5 are consistent. On the second wall 4, the M-shaped pipe 10 and L-shaped pipe 11 are respectively located in the second wall 4... On both sides, M-shaped pipe 10 is located in the first water tank 6, and L-shaped pipe 11 is located in the second water tank 7; on the third wall 5, M-shaped pipe 10 and L-shaped pipe 11 are located on both sides of the third wall 5, with M-shaped pipe 10 in the second water tank 7 and L-shaped pipe 11 in the third water tank 8; M-shaped pipe 10 is set above the interception net 9, and L-shaped pipe 11 is set below the interception net 9; circulation hole 12 is opened below the circulation wall 2, and the position of circulation hole 12 is 50cm higher than the shallowest depth of the bottom of the circulation tank. The circulation water pump is set at the shallowest position of the third water tank 8, and its highest position is lower than the circulation hole 12.

[0047] A method for sediment settling in an open circulating water tank includes the following steps:

[0048] S1: Add mud and water to the circulation tank. Since the bottom of the circulation tank is set at an angle, the mud and sand in the mud and water will be deposited at the bottom of the circulation tank due to gravity. Also, since the bottom of the circulation tank is set at an angle, the mud and sand will accumulate together along the angled bottom of the circulation tank.

[0049] S2: As the muddy water is added to the bottom of the circulation tank, the muddy water level gradually rises until it reaches the circulation hole 12, thus allowing the muddy water to enter other circulation tanks for sedimentation and filtration.

[0050] S3: As mud and water are continuously added, the mud and water level gradually rises because the amount of mud and water added is greater than the water output of circulation hole 12. As the mud and water rise, sedimentation occurs, and the mud and water rises to the circulation component; it then undergoes filtration again through the circulation component.

[0051] In a preferred embodiment of the present invention, in S3, the M-shaped pipe 10 and L-shaped pipe 11 of the circulation component are respectively disposed in the circulation pools on both sides of the circulation wall 2. The M-shaped pipe 10 is disposed above the circulation pool, and the L-shaped pipe 11 is disposed below the circulation pool. The muddy water enters the water storage chamber from the circulation pool through the M-shaped pipe 10, and then enters the circulation pool on the other side from the water storage chamber through the L-shaped pipe 11, thereby forming a siphon effect.

[0052] It should be noted that when cleaning the muddy water is necessary, it is first pumped into the first water tank 6. As the muddy water is pumped into the first water tank 6, the silt and debris in the muddy water gradually settle due to gravity. During the settling process, because the bottom of the first water tank 6 is smoothly inclined, the silt and debris at the bottom of the first water tank 6 slide to the deepest part of the first water tank 6 and accumulate there. At the same time, as the muddy water is gradually pumped into the first water tank 6, the water level in the first water tank 6 gradually rises until it reaches the circulation hole 12 below the second wall 4. At this point, the water level in the first water tank 6 is at the circulation hole 12, and the muddy water near the circulation hole is... During sedimentation, the muddy water, silt, and debris at the top separate and settle. The settled muddy water flows from the circulation hole 12 at the bottom of the first pool 6 to the second pool 7, thus completing the first sedimentation filtration. At this point, more muddy water to be filtered continues to be added to the first pool 6. Because the added amount exceeds the outflow, the water level in the first pool 6 continues to rise. Simultaneously, the water level in the second pool 7 also rises. During this rise, the muddy water that has undergone the first sedimentation filtration undergoes a second sedimentation. As the water level in the second pool 7 rises, it eventually reaches the circulation hole 12 at the bottom of the third wall 5, allowing the muddy water that has undergone the second sedimentation to flow from the circulation hole 12 at the bottom of the third wall 5. 2. The muddy water flows into the third pool 8 for a third sedimentation. In the first pool 6, after the first sedimentation, the muddy water flows from the circulation hole 12 at the bottom of the second wall 4 into the second pool 7. In the first pool 6, the inflow is greater than the outflow, so the water level is constantly rising. Of the M-shaped pipes 10 and L-shaped pipes 11 on both sides of the second wall 4, the M-shaped pipe 10 contacts the water first. After the front end of the M-shaped pipe 10 in the first pool 6 contacts the water, the M-shaped pipe 10 and the first pool 6 are communicating vessels, and the water level in the M-shaped pipe 10 is level with the water level in the first pool 6, until the water level rises to the first peak of the M-shaped pipe 10. At this point, the muddy water in the M-shaped pipe 10 changes direction at the first peak due to gravity. The reason is that the water in the M-shaped pipe 10 is driven to the middle position of the M-shape, and when the muddy water slides down the M-shaped pipe 10, a siphon effect is generated, drawing the muddy water in the first water tank 6 into the M-shaped pipe 10. Due to gravity and inertia, the muddy water is pushed to the second peak, where it turns again, thus enhancing the siphon effect. It then flows out from the tail of the M-shaped pipe 10 into the storage chamber. Since the M-shaped pipe 10 is located above the second wall 4, at the same time the water level in the first water tank 6 rises to the M-shaped pipe 10, the muddy water in the first water tank 6 is also settling. Therefore, the muddy water drawn by the M-shaped pipe 10 at this time has already settled. After being drawn into the storage chamber by the M-shaped pipe 10, the water level in the storage chamber within the second wall 4 rises, reaching the L-shaped pipe 11.The front end of the L-shaped pipe 11 is located inside the water storage chamber. As the water level in the storage chamber rises, muddy water enters from the front end of the L-shaped pipe 11 until it flows to the bend. The muddy water in the L-shaped pipe 11 then flows downwards from the bend due to gravity to the rear end of the L-shaped pipe 11, thus exiting the water storage chamber and flowing into the second water tank 7. At this point, the L-shaped pipe 11 generates a siphon effect, causing the muddy water that has settled in the upper part of the first water tank 6 to be drawn out through the siphon effect of the M-shaped pipe 10 and the L-shaped pipe 11. The first water tank 6 draws water into the second water tank 7. Due to the action of the L-shaped pipe 11 and the circulation hole 12, the inflow rate into the second water tank 7 is greater than the outflow rate. At this time, the water level in the second water tank 7 rises until it reaches the M-shaped pipe 10 above the second water tank 7. Then, the M-shaped pipe 10 and L-shaped pipe 11 on the third wall 5 and the M-shaped pipe 10 and L-shaped pipe 11 on the second wall 4 also experience a siphon effect, causing the muddy water in the second water tank 7 to flow into the third water tank 8. Similarly, the muddy water flowing into the third water tank 8 undergoes further sedimentation in the second water tank 7. The muddy water in pool 6 flows to pool 7 through circulation holes 12 under the second wall 4, and then to pool 8 through circulation holes 12 under the third wall 5. Because the muddy water contains silt and debris, these substances settle and accumulate at the bottom of the pools due to gravity. Since the bottoms of each pool are sloped, the silt and debris slide down and accumulate at the very bottom. Since the circulation holes 12 are located above the shallowest point of each pool bottom, the muddy water has already settled by the time the water level rises to the circulation holes 12. Afterwards, the muddy water flows through… The circulation hole 12 performs the first filtration. Since floating debris sometimes mixes with the muddy water, an intercepting net 9 is installed below the M-shaped pipe 10. When the M-shaped pipe 10 generates a siphon effect to perform the second filtration, the intercepting net 9 intercepts the floating debris. Simultaneously, as the water level rises to the M-shaped pipe 10, the muddy water has already settled. Then, the siphon effect of the M-shaped pipe 10 generates suction, transferring the settled muddy water to the next pool for further filtration. Finally, the filtered muddy water is pumped out by the circulating water pump in the third pool 8.
