Description

Technical Field

[0001] This utility model relates to the field of cooling water recycling technology, specifically a spray cooling water recycling device for a spray tower. Background Technology

[0002] The spray cooling water recycling equipment for spray towers mainly consists of a closed-loop circulation system composed of a circulating water pump group, a water collection tank and a water storage tank, a multi-stage filtration device, a water quality stabilization treatment unit, and supporting auxiliary systems such as a liquid level monitoring and automatic water replenishment device and a temperature control bypass valve group. It achieves the cascade purification and continuous reuse of cooling water through a technical path of physical filtration + chemical conditioning + dynamic balance control. Existing multi-stage circulating filtration devices have complex structures, resulting in larger footprints for recycling equipment and more subsequent cleaning and maintenance steps, thus reducing the practicality of the device. At the same time, during the initial filtration of the recycling equipment, the large particles of impurities in the spray water from the spray tower can easily clog the intercepting screen plate. If it is not cleaned in time, it will lead to a decrease in the filtration efficiency of the recycling equipment. Utility Model Content

[0006] As a preferred embodiment of this utility model, an electrically controlled magnet is embedded in one side of the magnetic adsorption block and on the outer wall of the fixed sleeve, a top block is installed on one side of the electrically controlled magnet and at the port of the fixed sleeve, a contact sensor is embedded in one side of the rotating shaft and on the inner wall of the mounting plate, wherein the contact sensor is located on one side of the top block, the receiving housing is installed on the side wall of the circulation processing box, and the receiving housing is located on one side of the baffle filter screen plate.

[0007] As a preferred embodiment of this utility model, a first baffle is installed on the inner wall of the circulation processing tank, wherein the first baffle is located on one side of the partition filter screen plate, and the top of the first baffle is lower than the port of the circulation processing tank. A liquid level sensor is installed on one side of the first baffle and on the inner wall of the circulation processing tank.

[0008] As a preferred embodiment of this utility model, the post-processing component includes a limiting guide rail and an installation frame. Two sets of limiting guide rails are provided and are respectively located on the opposing inner walls of the circulating processing box. A partition plate is slidably connected to the inner wall of the limiting guide rail. A limiting baffle is installed on one side of the partition plate and on the inner wall of the circulating processing box. The limiting baffle and the partition plate are connected by a sliding connection. The installation frame is installed on the outer wall of the circulating processing box.

[0009] As a preferred embodiment of this utility model, electrically controlled cylinders are symmetrically arranged on the outer wall of the mounting frame. One end of the electrically controlled cylinder penetrates the mounting frame and extends to the inner wall of the mounting frame where a pull rod is installed. A connecting block is installed at one end of the pull rod, and a partition plate is connected to one end of the connecting block. The top of the partition plate is lower than the port of the circulation processing box.

[0010] As a preferred embodiment of this utility model, a second baffle is installed on one side of the partition plate and on the inner wall of the circulation processing box, wherein there is a gap between the bottom of the second baffle and the bottom of the inner cavity of the circulation processing box, and a third baffle is installed on one side of the second baffle and on the inner wall of the circulation processing box, wherein the top of the third baffle is lower than the port of the circulation processing box, and an active adsorption block is provided between the third baffle and the second baffle and on the inner wall of the circulation processing box.

[0011] As a preferred embodiment of this utility model, a sludge discharge pipe is embedded in the bottom of the circulation treatment box, and a manual valve is installed at one end of the sludge discharge pipe.

The controller drives the servo motor to drive the rotating shaft and the baffle filter screen to rotate continuously, realizing the dynamic filtration of impurities on the surface of the cooling water in the circulation treatment box. When the screen plate rotates to the set position and triggers the contact sensor, the controller cuts off the power to the electromagnet, releasing its adsorption force on the magnetic adsorption block. The inclined structure of the screen plate guides the guide scraper to slide along the screen surface, efficiently scraping off the trapped impurities and guiding them into the receiving shell for centralized collection.

[0013] This invention, by incorporating a post-treatment component into a spray cooling water recycling device for a spray tower, enables the separation of the inner cavity of the circulating water tank to increase reaction time. A controller operates an electrically controlled cylinder, causing one end of the cylinder to move a connecting block downwards via a pull rod. This, in turn, causes the connecting block to move a partition plate downwards, allowing the partition plate to move up and down along the inner wall of a limiting guide rail. When the top of the partition plate is flush with the limiting baffle, the initially treated cooling water flows to the other side of the limiting baffle. Subsequently, as the cooling water passes through the second and third baffles, it is adsorbed by the activated adsorption blocks. The treated cooling water is then discharged through an outlet pipe, thus recycling the spray cooling water from the spray tower. The entire device is integrated into a single unit, with the post-treatment component providing separation to extend the reaction time. Attached Figure Description

The receiving housing 402 is installed on the side wall of the circulating processing box 2 and is located on one side of the baffle filter screen plate 406.

[0019] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A first baffle 412 is installed on the inner wall of the circulation treatment tank 2. The first baffle 412 is located on one side of the baffle filter screen 406, and the top of the first baffle 412 is lower than the port of the circulation treatment tank 2. A liquid level sensor 413 is installed on one side of the first baffle 412 and on the inner wall of the circulation treatment tank 2.

[0020] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 4 The post-processing component 5 includes a limiting guide rail 501 and a mounting frame 502. The limiting guide rail 501 is provided in two sets and is located on the inner walls of the circulating processing box 2 respectively. A partition plate 503 is slidably connected to the inner wall of the limiting guide rail 501. A limiting baffle 504 is installed on one side of the partition plate 503 and on the inner wall of the circulating processing box 2. The limiting baffle 504 and the partition plate 503 are connected by a sliding connection. The mounting frame 502 is installed on the outer wall of the circulating processing box 2. Electrically controlled cylinders 505 are symmetrically arranged on the outer wall of the mounting frame 502. One end of the electrically controlled cylinder 505 passes through the mounting frame 502 and extends to the inner wall of the mounting frame 502 where a pull rod 506 is installed. A connecting block 507 is installed at one end of the pull rod 506. One end of the connecting block 507 is connected to the partition plate 503. The top of the partition plate 503 is lower than the port of the circulating processing box 2.

[0021] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 4 A second baffle 508 is installed on one side of the partition plate 503 and on the inner wall of the circulation treatment box 2, wherein there is a gap between the bottom of the second baffle 508 and the bottom of the inner cavity of the circulation treatment box 2. A third baffle 509 is installed on one side of the second baffle 508 and on the inner wall of the circulation treatment box 2, wherein the top of the third baffle 509 is lower than the port of the circulation treatment box 2, and an active adsorption block 510 is provided between the third baffle 509 and the second baffle 508 on the inner wall of the circulation treatment box 2.

[0022] The bottom of the circulating treatment box 2 is embedded with a sludge discharge pipe 8. A manual valve 9 is installed at one end of the sludge discharge pipe 8. A push-pull trolley 10 is set directly below the manual valve 9 and on the inner wall of the mounting bracket 1. An electric slip ring is installed on the side wall of the fixing sleeve 405.

[0023] Based on the above structural features and connection relationships, the electric slip ring supplies power to the electrically controlled magnet 409 to enable the device to operate normally. The servo motor 404 operates at a low speed. When the guide scraper 407 slides down along the inclined baffle filter screen 406 to scrape away impurities, when the baffle filter screen 406 is moved away, the top block 410 will break contact with the contact sensor 411. At this time, the controller 3 controls the electrically controlled magnet 409 to be energized to generate magnetism, so that when the baffle filter screen 406 is perpendicular to the horizontal plane, the guide scraper 407 will slide down along the vertical baffle filter screen 406. This causes the guide scraper 407 to drive the magnetic adsorption block 408 and the electrically controlled magnet 409 to be magnetically fixed. The top block 410 is provided in multiple sets and is located on one side of the electrically controlled magnet 409 to facilitate setting the position parameters of the electrically controlled magnet 409, so that the controller 3 can control the electrically controlled magnet 409 at different positions to be energized and de-energized. The magnetic adsorption block 408 and the electrically controlled magnet 409 are connected by a magnetic connection. The controller 3 is electrically connected to the electrically controlled valve 6, servo motor 404, electrically controlled magnet 409, contact sensor 411, liquid level sensor 413 and electrically controlled cylinder 505 via wires. This connection enables the device to be powered on, thereby allowing the controller 3 to control the operation of the electrically controlled valve 6, servo motor 404, electrically controlled magnet 409, contact sensor 411, liquid level sensor 413 and electrically controlled cylinder 505.

[0024] Based on the above structural features and connection relationships, after the flocculation reaction is added to the inner cavity of the circulation treatment box 2, the impurities generated in the inner cavity of the circulation treatment box 2 will settle and accumulate in the sludge discharge pipe 8. The accumulated impurities can be discharged and collected simply by opening the manual valve 9.

[0025] This solution is used for the spray cooling water recycling equipment of the spray tower. When in operation, the electric control valve 6 is connected to the spray cooling water circulation pipeline of the spray tower. Then, the operator turns on the switch of the controller 3, so that the controller 3 controls the electric control valve 6 to open, so that the spray cooling water of the spray tower enters the circulation treatment tank 2 for recycling. When the cooling water enters the inner cavity of the circulation treatment tank 2, it will cause the liquid level sensor 413 to generate data, and then the liquid level sensor 413 will generate an electrical signal, which will be transmitted to the controller 3 through the wire. When the set liquid level parameter is reached, the controller 3 will control the electric control valve 6 to close.

[0026] By turning on the switch of controller 3, controller 3 controls servo motor 404 to operate, which causes the drive shaft of servo motor 404 to drive rotating shaft 403 to rotate. In turn, rotating shaft 403 drives baffle filter screen 406 to rotate cyclically through fixed sleeve 405. This causes baffle filter screen 406 to filter impurities on the surface of cooling water in the inner cavity of the circulating treatment box 2. At the same time, when baffle filter screen 406 rotates to a fixed position, it is located on one side of receiving housing 402 and is inclined relative to the horizontal plane. When fixed sleeve 405 drives top block 410 to move, top block 410 contacts contact sensor 411, causing contact sensor 411 to generate an electrical signal that is transmitted to controller 3 through wires.

[0027] The controller 3 de-energizes the electromagnet 409 on one side, causing it to lose its magnetism and thus lose its magnetic fixation to the magnetic adsorption block 408. Since the baffle filter screen plate 406 is inclined relative to the horizontal plane, the guide scraper 407 slides downward along the inclined baffle filter screen plate 406. This pushes the impurities on the surface of the baffle filter screen plate 406 to one side, causing them to fall into the inner cavity of the receiving shell 402 for collection. This solves the problem that when the recycling equipment performs preliminary filtration, the large particles of impurities in the spray water from the spray tower can easily clog the intercepting screen plate, leading to a decrease in the filtration efficiency of the recycling equipment if it is not cleaned in time.

[0028] The operator adds flocculant to the inner cavity of the circulating treatment tank 2. After the preliminary treatment is completed, the controller 3 is turned on, causing the controller 3 to control the electric cylinder 505 to operate. One end of the electric cylinder 505 moves the connecting block 507 downward via the pull rod 506. This causes the connecting block 507 to move the partition plate 503 downward, allowing the partition plate 503 to move up and down on the inner wall of the limit guide rail 501. When the top of the partition plate 503 is flush with the limit baffle 504, the cooling water from the preliminary treatment flows into the limit baffle. On the other side of plate 504, when the cooling water passes through the second baffle 508 and the third baffle 509, the cooling water is adsorbed by the active adsorption block 510. The treated cooling water is then discharged through the outlet pipe 7, so that the spray cooling water of the spray tower can be recycled and reused. The device is integrated into one piece of equipment. The post-treatment component 5 is used to extend the reaction time, thereby solving the problem that the existing multi-stage circulating filtration device has a large structure, which makes the recycling equipment occupy a large area and has many subsequent cleaning and maintenance steps, thus making the device impractical.

[0029] The electrically controlled valve 6, servo motor 404, electrically controlled magnet 409, contact sensor 411, liquid level sensor 413, electrically controlled cylinder 505, and controller 3 used in this utility model are all existing known electrical devices, and all can be directly purchased and used on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the electrically controlled valve 6, servo motor 404, electrically controlled magnet 409, contact sensor 411, liquid level sensor 413, electrically controlled cylinder 505, and controller 3 will not be described in detail here.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.
