Description

Technical Field

[0001] This invention belongs to the technical field of steam turbine water filtration mechanisms, specifically, it relates to an open-type water circulation filtration mechanism for steam turbines. Background Technology

[0002] Steam turbine open-loop water circulation filtration refers to the process of filtering water used in a steam turbine open-loop water circulation system. Open-loop water circulation means that the water interacts with the external environment during circulation, such as through natural evaporation. Open-loop water circulation often uses natural water sources from the external environment or a portion of the water in the steam turbine's circulating water system for circulation. The water in the steam turbine open-loop water circulation filtration is mainly used to cool equipment such as steam turbines. During the operation of the steam turbine, a large amount of heat is generated, which needs to be carried away by cooling water to maintain the normal operating temperature of the equipment.

[0003] Chinese patent CN220238027U discloses an open-type water circulation filtration mechanism for steam turbines, including a housing with a filtration structure inside and a sealing cover on top. The filtration structure includes a filter plate, support columns, a filter box, mounting holes, mounting blocks, a filter screen, and a filter layer. The filter plate is fixed to the inner wall of the filtration structure, and support columns are installed at each of the four corners. A filter box is fitted onto the top of the filter plate, and mounting holes are provided at each of the four corners of the filter box. This utility model facilitates the removal and replacement of the filter layer from the top of the device. The design is reasonable; by having wastewater enter from the bottom and filtered wastewater exit from the top, heavier impurities in the wastewater settle to the bottom during open-type water circulation treatment in the steam turbine, reducing the filtration burden on the filter layer. It can completely flush out impurities such as gravel and mud, preventing accumulation inside the mechanism.

[0004] The aforementioned prior art describes an open-type water circulation filtration mechanism for steam turbines. When filtering circulating water, it uses multiple stacked filter layers filled with materials such as activated carbon. These materials filter impurities in the circulating water, adsorbing them onto the outer walls of the activated carbon and other materials. However, if the user does not replace the internal filter layers for an extended period, the top filter layer comes into contact with impurities first, resulting in a higher adsorption of impurities compared to the bottom filter layer. Consequently, the bottom filter layer is not effectively utilized, leading to wasted use of the filter layers.

[0005] Therefore, we propose an open-type water circulation filtration mechanism for steam turbines to solve the problems mentioned above. Summary of the Invention

[0006] In view of the problem that the bottom filter layer in the existing multi-layer filter technology has less adsorption of impurities, resulting in the filter layer at the bottom not being well utilized, the purpose of this invention is to provide a steam turbine open-type water circulation filter mechanism.

[0008] Furthermore, the filter box has a first elongated hole on its side wall and a second elongated hole on its side wall.

[0009] Furthermore, a sealing ring is fitted on the side wall of the filter plate, and a water pump is fixedly installed on the side wall of the filter box. The output end of the water pump is fixedly connected to one end of the water inlet pipe.

[0010] Furthermore, a rotating shaft is fixedly connected through the side wall of the circular plate, and a motor is fixedly installed on the side wall of the support frame, with the output end of the motor fixedly connected to one end of the rotating shaft.

[0011] Furthermore, a baffle is slidably connected through the side wall of the filter box, a first magnetic block is fixedly connected to the top of the baffle, a second magnetic block is fixedly connected to the inner wall of the filter box, a first electromagnet is fixedly connected to the side wall of the baffle, and a second electromagnet is embedded in the side wall of the adjusting block.

[0012] Furthermore, the side wall of the adjusting block is provided with a long groove, which is connected to the short box. A long plate is slidably connected to the inner wall of the short box, and a protrusion is fixedly connected to the side wall of the long plate. A groove is provided on the side wall of the slot.

[0013] Furthermore, a second toothed plate is slidably connected to the inner wall of the long groove, the side wall of the second toothed plate is fixedly connected to the side wall of the long plate, a gear is rotatably connected to the inner wall of the long groove, a first toothed plate is slidably connected to the inner wall of the long groove, the first toothed plate is meshed with the gear, the second toothed plate is meshed with the gear, and the second toothed plate and the first toothed plate are misaligned.

[0014] Furthermore, a second abutment is slidably connected to the bottom of the adjusting block, a first abutment is fixedly connected to the side wall of the filter box, and the side wall of the second abutment and the side wall of the first toothed plate are fixedly connected.

[0015] Furthermore, multiple springs are fixedly connected inside the long groove, with one end of each spring fixedly connected to the side wall of the first toothed plate.

[0016] Furthermore, two sets of sliding grooves are symmetrically opened on the inner wall of the long groove, and sliders are slidably connected to the inner walls of the sliding grooves.

After the sequential replacement is completed, the baffle moves away with the adjusting block, and the water circulation filtration process can continue. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments.

[0023] To address the issue of limited adsorption of impurities in the bottom filter layer, resulting in insufficient consumption of materials like activated carbon and thus waste, such as... Figure 1 - Figure 7As shown: A steam turbine open-type water circulation filtration mechanism includes a filter box 1. A filter assembly 2 is fixedly installed on the inner wall of the filter box 1. The filter assembly 2 can filter the circulating water entering the filter box 1 and adsorb impurities in the circulating water. An adjustment assembly 3 is fixedly installed on the side wall of the filter box 1. Multiple support columns 5 are fixedly installed at the bottom of the filter box 1. The support columns 5 support the filter box 1, so that the filter box 1 can work stably during the water circulation filtration process. A sealing cover 6 is rotatably installed on the top of the filter box 1. Under normal conditions, the sealing cover 6 can cover the top of the filter box 1 to prevent external dust and other objects from entering the filter box 1. When it is necessary to replace or clean the internal structure of the filter box 1, the filter plate 203 and other structures can be easily removed.

[0024] Filter assembly 2 includes an inlet pipe 201, which is fixedly connected to the side wall of filter box 1. External circulating water can enter the filter box 1 through the inlet pipe 201 for filtration. A support plate 202 is symmetrically fixedly connected to the inner wall of filter box 1. Multiple filter plates 203 are slidably connected to the inner wall of filter box 1. The side wall of the bottom filter plate 203 abuts against the side wall of the support plate 202, thus supporting the filter plate 203. This ensures that when circulating water impacts the filter plate 203, it will not fall to the bottom of filter box 1. The filter screen of the filter plate 203... The pores are filled with activated carbon and other materials, which can adsorb impurities in the circulating water. The adjustment component 3 can replace the position of the filter plate 203, moving the filter plate 203 from the bottom to the top. After a long period of filtration, the bottom filter plate 203 consumes less activated carbon than the top filter plate 203. Therefore, by adjusting the position of the bottom filter plate 203 to the top, the activated carbon and other materials can be utilized more completely. The bottom of the filter box 1 is fixedly connected to the outlet pipe 205, and the filtered circulating water can be discharged through the outlet pipe 205.

[0025] The adjustment assembly 3 includes a support frame 301, which is fixedly connected to the side wall of the filter box 1. One end of the support frame 301 is fixedly connected to the side wall of an adjacent support column 5. The support frame 301 includes a U-shaped fixing plate and an inclined fixing plate. One end of the U-shaped fixing plate is fixed to the side wall of the filter box 1, and one end of the inclined fixing plate is fixed to the side wall of one of the support columns 5. The other end is fixed to the side wall of the U-shaped fixing plate, thereby maintaining the stability of the entire support frame 301. A circular plate 302 is rotatably connected to the side wall of the support frame 301 via a bracket. One end of the bracket is connected to the support frame 301. The support is fixed, while the top of the bracket rotates to support the circular plate 302, thus the bracket supports the circular plate 302 and the circular plate 302 can rotate at the same time. An electric push rod 303 is fixedly connected through the side wall of the circular plate 302. An adjusting block 304 is fixedly connected to the movable end of the electric push rod 303. The electric push rod 303 can control the horizontal position of the adjusting block 304, thus facilitating the adjustment of the position of the filter plate 203. A quick-release assembly 4 is fixedly installed on the side wall of the adjusting block 304. The quick-release assembly 4 can quickly fix and disassemble the filter plate 203 and the adjusting block 304.

[0026] The quick-release assembly 4 includes a short box 401, which is fixedly connected to the side wall of the adjusting block 304. The side wall of the filter plate 203 has a slot 403, and the short box 401 can be inserted into the slot 403 to connect the adjusting block 304 and the filter plate 203.

[0027] The filter box 1 has a first elongated hole 307 and a second elongated hole 308 on its side wall. The first elongated hole 307 and the bottom filter plate 203 are at the same horizontal level, while the second elongated hole 308 and the top filter plate 203 are at the same horizontal level. The diameters of the first elongated hole 307 and the second elongated hole 308 are slightly larger than the diameter of the filter plate 203, so that the filter plate 203 can be easily removed and inserted.

[0028] A sealing ring 204 is fitted onto the side wall of the filter plate 203. The sealing ring 204 is located on the side of the filter plate 203 near the first elongated hole 307 and the second elongated hole 308. During normal filtration, the sealing ring 204 can block the gaps between the filter plate 203 and the first elongated hole 307 and the second elongated hole 308, preventing water inside the filter box 1 from leaking to the outside through the first elongated hole 307 and the second elongated hole 308. The sealing ring 204 is made of rubber, so it can be squeezed when the filter plate 203 moves, without interfering with the movement of the filter plate 203. When the filter plate 203 to be adjusted moves into the second elongated hole 308 and is completely and tightly fitted inside the filter box 1, the sealing ring 204 will also... The filter plate 203, which falls onto the side wall of the first long hole 307, is blocked by the second long hole 308. The sealing ring 204 on the side wall of the filter plate 203 also blocks the first long hole 307. As a result, the circulating water inside the filter box 1 will not flow to the outside through the first long hole 307 and the second long hole 308. A water pump 206 is fixedly installed on the side wall of the filter box 1. The output end of the water pump 206 is fixedly connected to one end of the water inlet pipe 201. During the entire water circulation filtration process, the input end of the water pump 206 and the water outlet pipe 205 are connected to the external water inlet and outlet devices to carry out the water circulation filtration process. The water from the outside is drawn in by the water pump 206 and enters the filter box 1. The filtered water is then discharged to other external devices through the water outlet pipe 205, thus circulating.

[0029] A rotating shaft 306 is fixedly connected through the side wall of the circular plate 302, and a motor 305 is fixedly installed on the side wall of the support frame 301. The output end of the motor 305 is fixedly connected to one end of the rotating shaft 306, so that the motor 305 can drive the circular plate 302 to rotate through the rotating shaft 306, thereby driving the structure of the side wall of the circular plate 302 to rotate, so as to complete the process of replacing the filter plate 203.

[0030] A baffle 309 is slidably connected through and sealed to the side wall of the filter box 1. A first magnet 310 is fixedly connected to the top of the baffle 309, and a second magnet 311 is fixedly connected to the inner wall of the filter box 1. A first electromagnet 312 is fixedly connected to the side wall of the baffle 309, and a second electromagnet 313 is embedded in the side wall of the adjusting block 304. In the initial state, most of the baffle 309 is located outside the filter box 1. The first magnet 310 and the first electromagnet 312 can limit the baffle 309, preventing it from moving completely out of the filter box 1. The magnetic blocks 311 can attract each other and will not easily separate when the external force is small. When the first magnetic block 310 and the second magnetic block 311 attract each other, the baffle 309 can be more tightly pressed against the inner wall of the filter box 1, so that the water at the top of the baffle 309 will not flow into the filter plate 203. The first electromagnet 312 and the second electromagnet 313 can attract each other after being energized, and their attraction is greater than that of the first magnetic block 310 and the second magnetic block 311. Therefore, after the first electromagnet 312 and the second electromagnet 313 attract each other, they can drive the baffle 309 to move.

[0031] During the water circulation filtration process, first adjust the entire device to a suitable position (e.g., Figure 1 As shown), the water pump 206 and the outlet pipe 205 are then connected to the external circulating water pipe. The water pump 206 then draws water from the outside and filters the circulating water through the multi-layer filter plate 203. Finally, the water is discharged into the external pipe through the outlet pipe 205.

[0032] The control program is pre-set, and the adjusting component 3 and quick-release component 4 are started at regular intervals. After filtering the circulating water for a period of time, the electric push rod 303 is activated, which moves the adjusting block 304 to insert the short box 401 into the slot 403 near the first elongated hole 307, fixing the short box 401 and the filter plate 203. The filter plate 203 at the bottom can then move with the adjusting block 304. During the process of fixing the filter plate 203, the side wall of the adjusting block 304 simultaneously contacts the first electromagnet 31. The two side walls abut against each other, thereby pushing the baffle 309 to move. When it moves to the appropriate position, the baffle 309 abuts against the inside of the filter box 1, and the first magnetic block 310 and the second magnetic block 311 attract each other, making the baffle 309 abut against the inner wall of the filter box 1 even more, and it will not easily move with the adjusting block 304. Thus, the baffle 309 can block the water entering the filter box 1, preventing circulating water from falling into the filter plate 203 that has not yet been replaced when the filter plate 203 is replaced in sequence, which would reduce the filtration effect.

[0033] After the filter plate 203 is fixed, the electric push rod 303 is activated to pull the filter plate 203 to be adjusted out of the filter box 1 through the first elongated hole 307. The other filter plates 203 move under the action of gravity and fall to the top of the support plate 202. At this time, the motor 305 is activated, which drives the circular plate 302 to rotate. The circular plate 302 drives the filter plate 203 and other structures to rotate. The electric push rod 303 is activated again to insert the fixed filter plate 203 back into the filter box 1 through the second elongated hole 308, thus completing the replacement process.

[0034] After a long period of filtration, the activated carbon and other materials inside the top filter plate 203 are consumed more than those inside the bottom filter plate 203. As a result, the bottom filter plate 203 is not being utilized well. Therefore, after completing the process of changing the order of the filter plates 203, the user moves the bottom filter plate 203 to the top of all the filter plates 203. Compared with before the order was changed, the activated carbon inside the filter plate 203 that was not fully utilized can be better utilized, thereby improving the utilization rate of the entire filter plate 203.

[0035] To address the issue of not being able to quickly fix and unlock the filter layer and adjustment device when changing the filter layer in sequence, such as... Figure 1 - Figure 12 As shown: The adjusting block 304 has a long groove 402 on its side wall, which is connected to the short box 401. The opening of the long groove 402 is opposite to the opening of the short box 401, so the internal structure of the long groove 402 can adjust the position of the internal structure of the short box 401. The inner wall of the short box 401 is slidably connected to a long plate 404, and the side wall of the long plate 404 is fixedly connected to a protrusion 406. The side wall of the slot 403 has a groove 405, and the protrusion 406 can be inserted into the groove 405, thereby fixing the short box 401 and the filter plate 203, and thus fixing the filter plate 203 and the adjusting block 304. The protrusion 406 has a wedge-shaped structure, so when the protrusion 406 is inserted into the slot 403, it can slide against the side wall of the slot 403. When the protrusion 406 moves to the position of the groove 405, it can be easily inserted into the groove 405.

[0036] A second toothed plate 410 is slidably connected to the inner wall of the long groove 402. The side wall of the second toothed plate 410 is fixedly connected to the side wall of the long plate 404. A gear 408 is rotatably connected to the inner wall of the long groove 402. A first toothed plate 409 is slidably connected to the inner wall of the long groove 402. The first toothed plate 409 and the gear 408 are meshed together. The second toothed plate 410 and the gear 408 are meshed together. The second toothed plate 410 and the first toothed plate 409 are misaligned. Thus, no matter which toothed plate of the first toothed plate 409 and the second toothed plate 410 moves, the other toothed plate can be driven to move through the gear 408. Furthermore, the second toothed plate 410 can also drive the protrusion 406 to move during the movement.

[0037] The bottom of the adjusting block 304 is slidably connected to a second abutment plate 411. A first abutment plate 407 is fixedly connected to the side wall of the filter box 1. The side wall of the second abutment plate 411 is fixedly connected to the side wall of the first toothed plate 409. Thus, when the second abutment plate 411 moves, it can drive the first toothed plate 409 to move, so as to drive the protrusion 406 to move at the same time. Both the first abutment plate 407 and the second abutment plate 411 are wedge-shaped structures, which facilitates the sliding of the first abutment plate 407 and the second abutment plate 411 against each other. Since the movement trajectory of the second abutment plate 411 is restricted, when the position of the filter plate 203 is changed, the second abutment plate 411 and the first abutment plate 407 slide against each other. The second abutment plate 411 can only slide along a single point in the vertical direction, which can push the first toothed plate 409 to move. Thus, the first toothed plate 409 can drive the protrusion 406 to move. The protrusion 406 moves out of the groove 405, and the short box 401 and the filter plate 203 can be loosened.

[0038] Multiple springs 412 are fixedly connected inside the long slot 402. One end of the spring 412 is fixedly connected to the side wall of the first toothed plate 409. Thus, after the first toothed plate 409 and the second toothed plate 410 move under the action of external force, if the external force disappears or weakens, the spring 412 can drive the first toothed plate 409 and the second toothed plate 410 to reset.

[0039] Two sets of sliding grooves 413 are symmetrically opened on the inner wall of the long groove 402. A slider 414 is slidably connected to the inner wall of the sliding groove 413. The slider 414 is fixedly connected to the side wall of the adjacent first toothed plate 409 and second toothed plate 410, thereby restricting the movement trajectory of the first toothed plate 409 and the second toothed plate 410 and preventing the first toothed plate 409 and the second toothed plate 410 from shifting their positions during movement.

[0040] When replacing the filter plate 203, the filter plate 203 and the adjusting block 304 are first fixed. When the short box 401 is inserted into the slot 403, the protrusion 406 slides against the side wall of the slot 403 and is pressed by the second toothed plate 410, the gear 408 and the first toothed plate 409. When the protrusion 406 overlaps with the groove 405, the protrusion 406 moves into the groove 405 under the elastic action of the spring 412, thereby completing the fixing of the short box 401 and the filter plate 203.

[0041] After the fixed filter plate 203 moves with the adjusting block 304 and is reinserted into the filter box 1 through the second elongated hole 308, the second abutment plate 411 and the first abutment plate 407 slide against each other. When the filter plate 203 is fully inserted into the filter box 1 again, the second abutment plate 411 pushes the first toothed plate 409 to move. Then, through the gear 408, the second toothed plate 410 and other structures, the protrusion 406 moves and moves out of the groove 405. At this time, the short box 401 can move. Then, the electric push rod 303 separates the short box 401 from the slot 403, thereby achieving the purpose of quickly assembling and disassembling the adjusting block 304 and the filter plate 203. Thus, during the process of replacing the filter plate 203, the fixing and disassembly of the filter plate 203 can be completed, reducing the operation steps and improving the efficiency of the entire operation.

[0042] When the filter plate 203 to be replaced is inserted into the appropriate position, the first electromagnet 312 and the second electromagnet 313 are energized, and the first electromagnet 312 and the second electromagnet 313 attract each other. The attraction force is greater than that of the first magnetic block 310 and the second magnetic block 311. Then, when the adjusting block 304 and the filter plate 203 are separated, the baffle 309 can be moved to the initial position, so as not to block the water circulation filtration process, and the circulating water at the top of the baffle 309 can continue to be filtered.
