Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of energy-saving devices for thermal power plants, and in particular to a device for recycling and reusing drainage from a low-temperature sampling rack in a thermal power plant. Background Technology
[0002] To prevent corrosion, scaling, and salt accumulation in thermal equipment caused by abnormal steam and water quality, which could lead to safety accidents, thermal power plants need to effectively monitor water samples from condensate, deaerator, economizer, boiler water, saturated steam, superheated steam, reheat steam, internal cooling water, and closed-loop cooling water. These water samples are cooled and led to a low-temperature sampling rack. To ensure the timeliness, accuracy, and continuity of steam and water quality monitoring results, the sampling pipeline must be kept open for extended periods, and the sampling valve must remain open. Sampling wastewater is often discharged directly into industrial wastewater without being recycled, resulting in significant waste.
[0003] Currently, some existing cryogenic sampling rack drainage recovery devices in thermal power plants have certain shortcomings in the filtration stage. They typically only have simple filtration devices, and during long-term operation, impurities in the water easily accumulate on the filter components. For example, silt, rust particles, and colloidal substances in the water gradually clog the pores of the filter plates. Due to the lack of effective cleaning measures, the filtration efficiency of the filter plates continuously decreases as impurities accumulate. This slows down the flow of drainage through the filtration device, affecting the overall efficiency of the recovery device. To address this technical problem, this application proposes a cryogenic sampling rack drainage recovery and reuse device for thermal power plants. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a drainage recycling device for a low-temperature sampling rack in a thermal power plant. The motor is started to drive the first rotating roller to rotate, and the second rotating roller is driven to rotate via a belt. This causes the brush on the belt to move on the second filter plate, thereby cleaning the second filter plate. Pulling the pull rod causes the clamp to move, so that the clamp is released from the support frame, and the first filter plate is released from the support frame.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A device for recycling and reusing drainage from a low-temperature sampling rack in a thermal power plant includes a filter box. A water inlet pipe is fixedly connected to the left end of the filter box, and the main body of the low-temperature sampling rack is fixedly connected to the left end of the water inlet pipe. A water outlet pipe is fixedly connected to the right end of the filter box. Two sliding frames are fixedly connected to the top of the filter box, and a top cover is slidably connected to the adjacent ends of the two sliding frames. The front end of the top cover is connected to the filter box via a locking assembly. A second filter plate is fixedly connected to the right side of the inner wall of the filter box. A motor is mounted on the rear end of the filter box via a fixed frame. A first rotating roller is fixedly connected to the drive end of the motor. A second rotating roller is connected to the outer wall of the first rotating roller via a belt. The second rotating roller is rotatably connected to the inner wall of the filter box. A brush is fixedly connected to the outer wall of the belt, and the brush is located on the right side of the second filter plate. A support frame is fixedly connected to the left side of the inner wall of the filter box, and the first filter plate is connected to the left end of the support frame via a limiting assembly.
[0007] Furthermore, the limiting component includes a fixing block located at the left end of the support frame, a pull rod slidably connected to the inner wall of the fixing block, a clamping head fixedly connected to the right end of the pull rod, the clamping head being disposed on the inner wall of the support frame, and a spring being disposed on the outer wall of the pull rod.
[0008] Furthermore, the locking assembly includes a second fixing plate located at the front end of the top cover, a locking rod is provided at the front end of the second fixing plate, and a first fixing plate is rotatably connected to the bottom side of the rear end of the locking rod. The first fixing plate is fixedly connected to the front end of the filter box.
[0009] Furthermore, a sliding rod is fixedly connected to the right side of the inner wall of the filter box, and the brush is slidably connected to the inner wall of the sliding rod.
[0010] Furthermore, one end of the spring is disposed on the inner wall of the fixed block, and the other end of the spring is disposed on the outer wall of the pull rod.
[0011] Furthermore, both ends of the filter plate are fixedly connected with tenons, and both tenons are slidably connected to the inner wall of the support frame.
[0012] Furthermore, a handle is fixedly connected to the rear side of the top of the top cover.
[0013] Furthermore, limiting components are fixedly connected to both the top and bottom ends of the slide rod.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the starting motor drives the first rotating roller to rotate, and drives the second rotating roller to rotate via the belt, thereby driving the brush on the belt to move on the second filter plate. The brush cleans the second filter plate, effectively removing the impurities accumulated on the second filter plate, keeping the pores of the second filter plate unobstructed, ensuring that the drainage can pass through the second filter plate at a normal flow rate, and thus maintaining its filtration efficiency.
[0016] 2. In this utility model, pulling the lever moves the clamp head, causing the clamp head to release its engagement with the support frame, which in turn allows the filter plate to release its engagement with the support frame. Thus, the filter plate can be removed from the support frame via the tenon. A more suitable filter plate can be selected according to the actual situation, and the filtration strategy of the device can be flexibly adjusted to better meet the requirements of the recycled water quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-3This utility model provides an embodiment of a low-temperature sampling rack drainage recycling and reuse device for thermal power plants, comprising a filter box 1, an inlet pipe 2 fixedly connected to the left end of the filter box 1, a low-temperature sampling rack body 3 fixedly connected to the left end of the inlet pipe 2, an outlet pipe 4 fixedly connected to the right end of the filter box 1, two sliding frames 5 fixedly connected to the top of the filter box 1, and a top cover 6 slidably connected to the adjacent ends of the two sliding frames 5. The front end of the top cover 6 is connected to the filter box 1 through a second fixing plate 10, a clamping rod 9, and a first fixing plate 8. Inside the filter box 1... A filter plate 11 is fixedly connected to the right side of the filter box 1. A motor 12 is installed at the rear end of the filter box 1 via a fixed frame. A rotating roller 13 is fixedly connected to the drive end of the motor 12. A rotating roller 15 is connected to the outer wall of the rotating roller 13 via a belt 14. The rotating roller 15 is rotatably connected to the inner wall of the filter box 1. A brush 16 is fixedly connected to the outer wall of the belt 14. The brush 16 is located on the right side of the filter plate 11. A support frame 18 is fixedly connected to the left side of the inner wall of the filter box 1. A filter plate 19 is connected to the left end of the support frame 18 via a fixed block 21.
[0026] Specifically, in the wastewater recycling device, filter plate 11 typically undertakes a finer filtration task. As the filtration process proceeds, these impurities gradually accumulate on the surface of filter plate 11. Therefore, it is necessary to start motor 12 periodically to drive roller 13 to rotate, and under the action of belt 14, drive roller 15 to rotate, so that roller 13 and belt 14 tighten belt 14. When belt 14 moves, it can drive brush 16 to move on filter plate 11, thereby cleaning filter plate 11. This can effectively remove the impurities accumulated on filter plate 11, keep the pores of filter plate 11 unobstructed, and ensure that the wastewater can pass through filter plate 11 at a normal flow rate, thereby maintaining its filtration efficiency. Filter plate 19 is mainly used to intercept large particles of impurities in the wastewater. Water can be discharged into filter box 1 through inlet pipe 2 and discharged from filter box 1 through outlet pipe 4. Top cover 6 can slide on two sliding frames 5, so that top cover 6 can be opened from filter box 1.
[0027] Reference Figure 1 , Figure 4 and Figure 5The fixed block 21 is located at the left end of the support frame 18. A pull rod 22 is slidably connected to the inner wall of the fixed block 21. A clamp 23 is fixedly connected to the right end of the pull rod 22. The clamp 23 is set on the inner wall of the support frame 18. A spring 24 is set on the outer wall of the pull rod 22. The fixed plate 20 is located at the front end of the top cover 6. A clamp 9 is set at the front end of the fixed plate 20. A fixed plate 18 is rotatably connected to the bottom side of the rear end of the clamp 9. The fixed plate 18 is fixedly connected to the front end of the filter box 1. A slide rod 17 is fixedly connected to the right side of the inner wall of the filter box 1. A brush 16 is slidably connected to the inner wall of the slide rod 17. One end of the spring 24 is set on the inner wall of the fixed block 21. The other end of the spring 24 is set on the outer wall of the pull rod 22. The front and rear ends of the filter plate 19 are fixedly connected to tenons 20. Both tenons 20 are slidably connected to the inner wall of the support frame 18. A handle 7 is fixedly connected to the rear side of the top end of the top cover 6. Limiting parts are fixedly connected to the top and bottom ends of the slide rod 17.
[0028] Specifically, different periods or different drainage sources may have different requirements for filter plate 11. Simply pull the lever 22 to move the clamp 23, causing it to disengage from the support frame 18. Then, drag the fixing block 21 upwards to remove filter plate 19 from the support frame 18 via the tenon 20. A more suitable filter plate 19 can be selected according to the actual situation, allowing for flexible adjustment of the device's filtration strategy to better meet the requirements of recycled water quality. Conversely, pulling the lever 22 to install filter plate 19 onto the support frame 18 via the tenon 20 will... Under the action of spring 24, the clamp 23 can be popped into the slot of the support frame 18 to limit the filter plate 19 and install it on the support frame 18. Rotating the clamp 9 can disengage it from the fixing plate 10, which can separate the filter box 1 and the top cover 6. The top cover 6 can be opened more easily through the handle 7 to clean the inside of the filter box 1. The slide rod 17 can make the brush 16 move more stably on the filter plate 11. The limiting part on the slide rod 17 restricts the movement distance of the brush 16, so that it can only move back and forth on the filter plate 11.
[0029] Working principle: Water from the main body 3 of the low-temperature sampling frame is discharged into the filter box 1 through the inlet pipe 2 and filtered sequentially through filter plate 19 and filter plate 11. After the device has been used for a period of time, the motor 12 is started, which drives the first roller 13 to rotate. Under the action of the belt 14, the second roller 15 rotates, causing the first roller 13 and the belt 14 to tighten the belt 14. When the belt 14 moves, it can drive the brush 16 to move on the filter plate 11, thereby cleaning the filter plate 11. When it is necessary to adjust the filtration strategy of the device, the pull rod 22 is pulled, which moves the clamp 23, causing the clamp 23 to release from the support frame 18. After the filter plate 19 is removed from the support frame 18 by pulling the fixing block 21 upwards via the tenon 20, the filter plate 19 can be removed from the support frame 18 by pulling the lever 22. Conversely, after the filter plate 19 is installed onto the support frame 18 via the tenon 20 by pulling the lever 22, the clip 23 can be popped into the slot of the support frame 18 by the action of the spring 24, thus limiting the filter plate 19 and installing it onto the support frame 18. The filtered water will be discharged to a suitable position through the outlet pipe 4. When the device is not in use, rotate the lever 9 to release the locking of the fixing plate 10, and open the top cover 6 from the filter box 1 by holding the handle 7 and sliding the frame 5 to clean the accumulated material inside the filter box 1.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
