Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of water separation devices, specifically relating to a high-efficiency water separation device. Background Technology
[0002] Slag bins are devices used for material transfer and storage in slag removal systems. They receive materials from conveying equipment, store them briefly, and then transfer them to other locations. Due to the high moisture content of the materials, the slag bins require static dehydration during storage to reduce the amount of slag-water content and prevent spillage during transport. In related technologies, a water separation device is typically installed at the bottom of the bin to separate the slag-water while the material is stationary. However, this dehydration efficiency is low because the slag-water in the material at the top needs to move to the bottom before it can be separated from the device. Furthermore, the slag-water in the material at the top carries many impurities as it moves towards the bottom, causing them to accumulate and clog the water separation device, further affecting dehydration efficiency. Therefore, a highly efficient water separation device is urgently needed to solve these problems. Utility Model Content
[0003] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a high-efficiency water separation device.
[0004] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:
[0005] A high-efficiency water separation device includes a bottom cone of a slag bin, which has a conical structure that is wider at the top and narrower at the bottom. A closed annular water separation tank is installed at the bottom of the bottom cone. A discharge valve is slidably installed at the bottom of the closed annular water separation tank. A drain pipe is also installed on one side of the bottom of the closed annular water separation tank. The output end of the drain pipe is connected to a sedimentation slag water hopper. An overflow pipe is installed on one side of the top of the sedimentation slag water hopper. Side wall water separation components are installed on the four sides inside the bottom cone of the slag bin. The output end of the side wall water separation components is connected to the closed annular water separation tank. An inner cylinder water separation component is installed inside the closed annular water separation tank. Backwash pipes for the side wall water separation components and the inner cylinder water separation components are installed on the outside of the closed annular water separation tank. The output end of the backwash pipes for the side wall water separation components is connected to the side wall water separation components, and the output end of the backwash pipes for the inner cylinder water separation components is connected to the inner cylinder water separation components.
[0006] Further specifying, the sidewall water separation component includes an installation member extending along the height direction of the slag bin bottom cone. Rectangular plates are installed on both sides of the installation member, forming a water separation component with a triangular cross-section. The installation member is mounted on the inner wall of the slag bin bottom cone, with the rectangular plates facing inwards. Filter holes are provided on the rectangular plates, and filter screens are installed within these holes. This structural design further increases the contact area with the slag material, improving the effectiveness of the water separation component.
[0007] Furthermore, the enclosed annular water separation tank is equipped with switch doors on both the front and rear sides. This structural design facilitates the opening of the switch doors to remove the internal inner cylinder water separation assembly for maintenance and replacement.
[0008] Furthermore, the overflow pipe is designed with an inclined structure from the outside to the inside and from the bottom to the top, with an inclination angle of 5°. This structural design facilitates the discharge of overflowing sludge and water.
[0009] Further specifying, it also includes a cylinder, the power output end of which is connected to the ash discharge valve, and the cylinder is connected to a control box installed in the control room. This structural design facilitates the control of the ash discharge valve's opening and closing, making it convenient for operation.
[0010] Furthermore, manually adjustable turbine boxes are installed on all four sides between the closed annular water separation tank and the ash discharge valve. This structural design allows for manual adjustment of the worm gear clearance of the turbine boxes, eliminating the need for sealing rings between the closed annular water separation tank and the ash discharge valve, thus preventing slag leakage during operation.
[0011] The beneficial effects of this utility model are as follows: This utility model has a large water separation area by setting a side wall water separation component, and is equipped with a backwashing pipeline for the side wall water separation component, resulting in high water separation efficiency. It is easy to disassemble and maintain. By setting a closed annular water separation tank and adopting a fully enclosed streamlined water separation ash and slag tank, it is not easy to accumulate slag and water. The fully enclosed structure, with an inner cylinder water separation component inside, further increases the water separation area. At the same time, the backwashing pipeline for the inner cylinder water separation component further increases the water separation efficiency and can effectively prevent the side wall water separation component and the inner cylinder water separation component from becoming clogged and reducing dehydration efficiency.

[0019] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] like Figure 1-4 As shown, the high-efficiency water separation device of this utility model has a cone-shaped structure with a larger upper part and a smaller lower part as the bottom cone of the slag bin. A closed annular water separation tank 2 is installed at the bottom of the bottom cone of the slag bin. A slidable ash discharge valve 3 is installed at the bottom of the closed annular water separation tank 2. A drain pipe 4 is also installed on one side of the bottom of the closed annular water separation tank 2. The output end of the drain pipe 4 is connected to a sedimentation slag water hopper 5. An overflow pipe 6 is installed on one side of the top of the sedimentation slag water hopper 5. Side wall water separation components 7 are installed on the four sides inside the bottom cone of the slag bin. The output end of the side wall water separation components 7 is connected to the closed annular water separation tank 2. An inner cylinder water separation component 8 is installed inside the closed annular water separation tank 2. A backwash pipe 9 for the side wall water separation component and a backwash pipe 10 for the inner cylinder water separation component are installed on the outside of the closed annular water separation tank 2. The output end of the backwash pipe 9 for the side wall water separation component is connected to the side wall water separation component 7. The output end of the backwash pipe 10 for the inner cylinder water separation component is connected to the inner cylinder water separation component 8.
[0021] Preferably, the sidewall water separation component 7 includes a mounting member 11, which extends along the height direction of the bottom cone 1 of the slag bin. Rectangular plates 12 are mounted on both sides of the mounting member 11, forming a water separation component with a triangular cross-section. The mounting member 11 is installed on the inner wall of the bottom cone 1 of the slag bin, with the rectangular plates 12 facing inwards. Filter holes 13 are provided on the rectangular plates 12, and filter screens 14 are installed within the filter holes 13. This structural design further increases the contact area with the slag material, improving the performance of the water separation component. In practice, other structural shapes of the sidewall water separation component 7 can also be considered depending on the specific circumstances.
[0022] Preferably, the closed annular water separation tank 2 has switch boxes 15 on both the front and rear sides. This structural design facilitates opening the switch boxes 15 to remove the inner cylinder water separation assembly 8 for maintenance and replacement. In practice, other switch structure shapes for the closed annular water separation tank 2 can also be considered depending on the specific circumstances.
[0023] Preferably, the overflow pipe 6 is designed with an inclined structure from the outside to the inside and from the bottom to the top, with an inclination angle of 5°. This structural design facilitates the discharge of overflowing sludge and water. In practice, other structural shapes of the overflow pipe 6 can also be considered depending on the specific circumstances.
[0024] Preferably, the system also includes a cylinder 16, the power output end of which is connected to the ash discharge valve 3, and the cylinder 16 is connected to a control box 18 installed in the control room. This structural design facilitates the control of the opening and closing of the ash discharge valve 3, making it convenient for operation. In practice, other control switch structures for the ash discharge valve 3 can also be considered depending on the specific circumstances.
[0025] Preferably, manually adjustable turbine boxes 17 are installed on all four sides between the closed annular water separation tank 2 and the ash discharge valve 3. This structural design allows for manual adjustment of the worm gear clearance of the turbine box 17, eliminating the need for sealing rings between the closed annular water separation tank 2 and the ash discharge valve 3, thus preventing slag leakage during operation. In practice, other clearance adjustment structures between the closed annular water separation tank 2 and the ash discharge valve 3 can also be considered depending on the specific circumstances.
[0026] In this embodiment, during use, after the material output from the pulverized coal boiler enters the bottom cone 1 of the slag bin and moves towards the bottom along the bottom cone 1, the sidewall water separation component 7 separates the material, reducing the amount of slag water carried by the material. The remaining material enters the closed annular water separation tank 2 and is separated by the inner cylinder water separation component 8. To prevent blockage of the sidewall water separation component 7 and the inner cylinder water separation component 8, after a period of use, the sidewall water separation component 7 and the inner cylinder water separation component 8 are flushed through the backwash pipe 9 and the backwash pipe 10. The process involves rinsing to prevent blockage of the sidewall water separation assembly 7 and the inner cylinder water separation assembly 8. The sludge and water separated by the sidewall water separation assembly 7 and the inner cylinder water separation assembly 8 are then fed into the sedimentation sludge and water hopper 5 through the drain pipe 4. The sludge and water settle in the sedimentation sludge and water hopper 5, causing fixed impurities to sink to the bottom of the sedimentation sludge and water hopper 5. The sludge and water are then discharged from the sedimentation sludge and water hopper 5 through the overflow pipe 6. After the water separation process is completed, the ash discharge valve 3 is opened by the cylinder 16. The material that has undergone water separation is then discharged from the bottom of the closed annular water separation tank 2. The operators collect the discharged material for the next step of the operation.
[0027] When the material enters the bottom cone 1 of the slag bin and remains stationary, the slag water in the material will move downwards due to gravity. As the slag water moves, it will flow onto the inner wall of the bottom cone 1 of the slag bin and come into contact with the side wall water separation component 7. The slag water can seep out from the material through the filter holes 13 of the rectangular plate 12 on the side wall water separation component 7. The filter screen 14 inside the filter hole 13 can intercept the material, while the slag water in the material can be separated from the material by passing through the filter screen 14. The slag water continues to move and enters the bottom of the closed annular water separation tank 2 and is discharged from the drain pipe 4. After the material moves into the closed annular water separation tank 2, the inner cylinder water separation component 8 performs water separation function to separate solids and liquids, so that the separated slag water is discharged from the drain pipe 4.
[0028] After prolonged use, the inner cylinder water separation component 8 can be removed for maintenance and replacement by opening the switch box door 15, which is convenient for operation.
[0029] Among them, a manually adjustable turbine box 17 is installed between the closed annular water separation tank 2 and the ash discharge valve 3. The gap is adjusted by a worm gear. The closed annular water separation tank 2 and the ash discharge valve 3 do not require sealing rings. During operation, there is no slag leakage. By adjusting and controlling the manually adjustable turbine box 17, the workload of on-site staff can be effectively reduced, work efficiency can be improved, the old-fashioned slag discharge door sealing gasket can be eliminated, and daily maintenance can be facilitated.
[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
