Description

Technical Field

[0001] This utility model relates to the field of resin capture technology, specifically a vertical resin capture device for water treatment in thermal power plants. Background Technology

[0002] In the water treatment process of thermal power plants, ion exchange resin is crucial for ensuring water quality meets standards. However, under long-term operation, the resin is easily damaged by factors such as water flow impact and chemical corrosion, and can escape with the water flow. Once this broken resin flows into subsequent systems, it will clog pipes, pollute the water, and greatly threaten the safe and stable operation of power plant equipment. Vertical resin traps for thermal power plant water treatment have emerged to address this need, shouldering the important responsibility of intercepting resin and ensuring the normal operation of the system. As thermal power plants continue to increase their requirements for efficient and stable production, higher standards are being set for the performance of resin traps.

[0003] While traditional vertical resin traps have some effect on filtering resin, they are difficult to automatically clean up the filtered resin. Currently, most cleaning is done manually, which not only consumes a lot of manpower and time, but also causes the filter screen to become clogged due to untimely cleaning, reducing filtration efficiency. Moreover, the manual cleaning process is cumbersome and requires shutdown, affecting the continuous operation of the water treatment system in thermal power plants. Therefore, there is an urgent need for a vertical resin trap for thermal power plant water treatment to solve the above problems. Utility Model Content

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.

[0022] Please see Figure 1-5 This utility model provides a vertical resin trap for water treatment in thermal power plants, comprising a main frame 1, a filter screen 2 fixedly connected to the inner wall of the main frame 1, a filter assembly 3 provided on the inner wall of the main frame 1, the filter assembly 3 including two rotating columns 301, both rotating columns 301 being rotatably connected to the inner wall of the main frame 1, rotating wheels 302 fixedly connected to the surface of the rotating columns 301, the same filter belt 303 sleeved on the surface of the two rotating wheels 302, two rotating columns 304 rotatably connected to the inner wall of the main frame 1, rotating wheels 305 fixedly connected to the surface of the rotating columns 304, the same conveyor belt 306 sleeved on the surface of the two rotating wheels 305, the conveyor belt... Multiple first cleaning brushes 307 are fixedly connected to the surface of 306. Through the set filter assembly 3, it is easy to intercept and filter the floating resin. The rotation of the filter belt 303 conveys the resin filtered down the surface of the filter belt 303 to the right. The side wall of the conveyor belt 306 is in contact with the surface of the filter belt 303, so that the moving first cleaning brushes 307 scrape and carry away the resin filtered down the surface of the filter belt 303. This facilitates timely and automatic cleaning of the resin filtered down the filter belt 303, so that the surface of the filter belt 303 maintains a good filtration effect and avoids the resin from squeezing each other through the surface of the filter belt 303 and clogging the surface of the filter screen 2.

[0023] Furthermore, a motor 317 is fixedly connected to the side wall of the main frame 1, and a linkage column 308 is fixedly connected to the output end of the motor 317. A first synchronous pulley 309 is fixedly connected to the surface of the linkage column 308 and the surface of the rotating column 301 located on the right. The same first belt 310 is sleeved on the surface of the two first synchronous pulleys 309. The motor 317 facilitates the provision of kinetic energy to the linkage column 308.

[0024] Furthermore, a positioning block 311 is fixedly connected to the side wall of the main frame 1, and a movable column 312 is rotatably connected to the inner wall of the positioning block 311. A second synchronous wheel 313 is fixedly connected to both the surface of the movable column 312 and the surface of the linkage column 308. The same second belt 314 is fixedly connected to the surfaces of the two second synchronous wheels 313. The positioning block 311, the movable column 312, and the second synchronous wheel 313 cooperate with each other to facilitate the rotation of the rotating column 304.

[0025] Furthermore, a first bevel gear 315 is fixedly connected to the surface of the movable column 312, and a second bevel gear 316 is fixedly connected to the surface of the lower rotating column 304. The first bevel gear 315 and the second bevel gear 316 are meshed and connected. The first bevel gear 315 and the second bevel gear 316 are used in cooperation with each other, which makes it easy to switch the axis of rotation of the movable column 312.

[0026] Furthermore, a sliding groove 318 is provided on the side wall of the main frame 1, and a collection box 319 is slidably connected to the inner wall of the sliding groove 318. A plurality of scraping grooves 320 are provided on the bottom surface of the collection box 319. The collection box 319 and the scraping grooves 320 cooperate with each other to facilitate the collection of resin on the surface of the first cleaning brush 307.

[0027] Furthermore, a plurality of second cleaning brushes 321 are fixedly connected to the surface of the filter belt 303. The flexibility of the second cleaning brushes 321 is greater than that of the first cleaning brushes 307. The second cleaning brushes 321 facilitate the cleaning of resin on the surface of the filter screen 2. The first cleaning brushes 307, which have a hardness greater than that of the second cleaning brushes 321, facilitate the cleaning of resin on the surface of the second cleaning brushes 321.

[0028] Working Principle: The filter assembly 3 causes the output of motor 317 to rotate, which in turn drives the linkage column 308. The rotation of linkage column 308, through the interaction of the first synchronous pulley 309 and the first belt 310, drives the rotating column 301 to rotate. The rotation of rotating column 301, in turn, drives the filter belt 303 to rotate. Simultaneously, the rotation of linkage column 308, through the interaction of the second synchronous pulley 313 and the second belt 314, drives the movable column 312 to rotate. The rotation of movable column 312, through the interaction of the first bevel gear 315 and the second bevel gear 316, switches the output axis. Thus, the rotation of linkage column 308 causes the rotating column 304 to rotate, which in turn drives the conveyor belt 306 to rotate synchronously. This multi-functional linkage reduces overall energy consumption and resource usage. The filter belt 303 facilitates the removal of floating tree branches. The resin is intercepted and filtered. The filter belt 303 rotates, conveying the resin filtered from its surface to the right. Simultaneously, the conveyor belt 306 rotates synchronously. The side wall of the conveyor belt 306 is in contact with the surface of the filter belt 303, allowing the moving first cleaning brush 307 to scrape away the resin filtered from the surface of the filter belt 303. This facilitates timely and automatic cleaning of the resin filtered from the filter belt 303, maintaining a good filtration effect on the surface of the filter belt 303 and preventing resin from being squeezed together and clogging the surface of the filter screen 2. As the conveyor belt 306 continues to rotate, the first cleaning brush 307 passes through the inner wall of multiple scraping grooves 320. The multiple scraping grooves 320 facilitate the scraping of resin from the surface of the first cleaning brush 307 and collects it inside the collection box 319, thus facilitating the unified collection of the filtered resin.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
