Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, specifically to a cooling tower that facilitates the cleaning of scale. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. It utilizes the heat exchange between water and air to generate steam, and the steam evaporates and carries away the heat to achieve evaporative heat dissipation, convective heat transfer, and radiative heat transfer. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the entire system.

[0003] The existing patent application, with publication number CN111288816A and publication date June 16, 2020, is titled "A Cooling Tower for Easy Descaling." It includes a cooling assembly, a descaling assembly, and a support assembly. The cooling assembly comprises a shell, a motor, a fan, a water distributor, a water spray packing layer, and pipes. The motor is fixedly connected to the upper inner surface of the shell, and its output end is rotatably connected to the fan. To clean scale, the roller shutter can be pulled upwards using the handle, allowing the spray system inside the cooling tower to spray the air inlet screen. The roller shutter prevents the spray liquid from spraying outwards. Electric push rods are located on the left and right sides of the lower inner surface of the tower base. Since the top of the electric push rod is fixed to the filter screen, and the outer wall of the filter screen has a brush, the electric push rods are raised and lowered by adjusting the remote control, thereby raising and lowering the brush and cleaning the air inlet screen. This enhances the cooling tower's efficiency and ensures its long-term use.

[0004] The above application has shortcomings. When cleaning the air inlet screen on the cooling tower, it is generally necessary for staff to use tools to manually scrape off the scale. This method of descaling is labor-intensive. Adding a corresponding descaling mechanism for automatic descaling requires an additional drive source to drive the descaling mechanism, resulting in high production and subsequent operating costs. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling tower that facilitates the cleaning of scale, thereby overcoming the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A cooling tower for easy scale removal includes a tower body with an air inlet grille, a packing layer installed inside the tower body, and a water supply pipe installed through the packing layer. An upper scraper and a lower scraper, which rotate synchronously in opposite directions, are rotatably sleeved on the outside of the water supply pipe. A grille cleaning assembly is slidably installed inside the air inlet grille, with the top of the upper scraper abutting against the top of the grille cleaning assembly and the bottom of the lower scraper abutting against the bottom of the grille cleaning assembly. When the upper and lower scrapers rotate synchronously in opposite directions, the grille cleaning assembly is moved back and forth on the air inlet grille.

[0008] Preferably, a pump body is installed at the bottom of the tower body, and the bottom of the water delivery pipe is connected to the pump body.

[0009] Preferably, the water supply pipe fitting has an opening, a connecting sleeve is rotatably sleeved outside the opening, the upper scraper is fixed to the connecting sleeve, and multiple scrapers are vertically fixed inside the opening, with the scrapers abutting against the inner wall of the connecting sleeve.

[0010] Preferably, a transmission sleeve is rotatably fitted at the bottom of the water supply pipe fitting, and the lower scraper is fixed to the transmission sleeve.

[0011] Preferably, a driving component is installed at the bottom of the tower body, which is connected to the transmission sleeve. Both the connecting sleeve and the transmission sleeve are fixedly connected to a transmission bevel gear at opposite ends. The water supply pipe is rotatably mounted with a connecting bevel gear that meshes with the two transmission bevel gears respectively.

[0012] Preferably, the bar cleaning assembly includes a connecting rod slidably installed on the inner wall of the tower body, and a descaling scraper is fixedly connected to one side of the connecting rod, the descaling scraper contacting each bar on the air inlet bar.

[0013] Preferably, a pair of elastic abutment members are installed on the other side of the connecting rod, and the pair of elastic abutment members respectively abut against the upper scraper and the lower scraper.

[0014] Preferably, a pair of elastic abutment members are slidably mounted on the top and bottom of the connecting rod, and a compression spring is installed between the elastic abutment members and the connecting rod.

[0015] Preferably, the bottom of the inner wall of the tower body is provided with a return water cavity, and the outer wall of the transmission sleeve is provided with a plurality of water guide grooves in a ring. The water guide grooves are connected to the water conveying pipes and are located between the packing layer and the return water cavity.

[0016] Preferably, a shaft fixed to a connecting bevel gear is rotatably installed inside the water supply pipe fitting, and a filter screen is also fixedly embedded inside the water supply pipe fitting. An impurity crushing component is rotatably installed at the bottom of the filter screen, and the shaft is connected to the impurity crushing component in a transmission connection.

[0017] In the above technical solution, by setting up an upper scraper and a lower scraper that rotate synchronously in opposite directions, the upper and lower scrapers clean the packing and chassis inside the cooling tower when they rotate synchronously. At the same time, the upper and lower scrapers will also move the grille cleaning component from two opposite directions in sequence, allowing the grille cleaning component to move back and forth on the air inlet grille, thereby scraping off the scale and residual water stains on the grille. There is no need to install a separate drive unit to drive the grille cleaning component, reducing the power consumption generated when cleaning scale.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] Please see Figure 1-7 This invention provides a cooling tower for easy scale removal, comprising a tower body 1 with an air inlet grille 101, a packing layer 102 installed inside the tower body 1, and a water supply pipe 2 installed through the packing layer 102. An upper scraper 3 and a lower scraper 4, rotating synchronously in opposite directions, are rotatably sleeved on the outside of the water supply pipe 2. A grille cleaning assembly 5 is slidably installed inside the air inlet grille 101, with the upper scraper 3 abutting against the top of the grille cleaning assembly 5 and the lower scraper 4 abutting against the bottom of the grille cleaning assembly 5. When the upper scraper 3 and the lower scraper 4 rotate synchronously in opposite directions, the grille cleaning assembly 5 is sequentially moved, causing it to move back and forth on the air inlet grille 101.

[0032] Specifically, a base plate 104 is installed at the bottom of the inner wall of the tower body 1. An air inlet grille 101 is arranged in a circle between the tower body 1 and the base plate 104. Several spray pipes 207 are installed on the top of the water supply pipe fitting 2 above the packing layer 102, and the multiple spray pipes 207 are distributed in a ring on the water supply pipe fitting 2. The water supply pipe fitting 2 delivers hot water to each spray pipe 207. The hot water is diffused and sprayed onto the top surface of the packing layer 102 through the spray pipes 207. When the water passes through the packing layer 102, it is heat-exchanged by the packing layer 102. The cooled water drips back onto the base plate 104 and is then recycled. The upper scraper 3 and the lower scraper 4 rotate synchronously, but in opposite directions. The top of the upper scraper 3 contacts the bottom surface of the packing layer 102, and the bottom of the lower scraper 4 contacts the base plate 104. The upper scraper 3 rotates in the following manner. The scraper 4, while rotating, scrapes away scale and residual water droplets from the bottom surface of the packing layer 102, preventing cooling water from adhering to the packing layer 102 for extended periods. Multiple grid cleaning components 5 are provided. Meanwhile, multiple support rods 105 are vertically arranged in a ring on the air inlet grid 101, separating the multiple grid cleaning components 5. When the upper scraper 3 rotates, it pushes the grid cleaning components 5 on the air inlet grid 101 in one direction. When the grid cleaning component 5 encounters a support rod 105, it stops. When the lower scraper 4 rotates, it pushes the grid cleaning component 5 in the other direction, causing it to press against another support rod 105. As the grid cleaning component 5 moves back and forth on the air inlet grid 101, it scrapes away the scale on the grid.

[0033] Compared with the prior art, the embodiments of the present invention, by setting up an upper scraper 3 and a lower scraper 4 that rotate synchronously in opposite directions, clean the packing material and chassis 104 inside the cooling tower when the upper scraper 3 and the lower scraper 4 rotate synchronously. At the same time, the upper scraper 3 and the lower scraper 4 will also move the grille cleaning component 5 from two opposite directions in sequence, so that the grille cleaning component 5 moves back and forth on the air inlet grille 101, thereby scraping off the scale and residual water stains on the grille. There is no need to install a separate drive unit to drive the grille cleaning component 5, reducing the power consumption generated when cleaning scale.

[0034] In a further embodiment of the present invention, a pump body 6 is installed at the bottom of the tower body 1, and the bottom of the water supply pipe 2 is connected to the pump body 6. A drain outlet is provided on the chassis 104, which is connected to the pump body 6. Specifically, the pump body 6 is used to transport or recover cooling water. When the pump body 6 transports cooling water that has absorbed heat, it will transport the cooling water to each spray pipe 207. Then, the cooling water with heat is sprayed onto the packing layer 102 through the spray pipe 207. The pump body 6 can also recover and extract the cooling water that has accumulated on the cooling tower chassis 104 after heat exchange, so as to realize the recycling of cooling water.

[0035] In a further embodiment of the present invention, the water supply pipe fitting 2 has an opening 201, and a connecting sleeve 202 is rotatably sleeved on the opening 201. Sealing rings are installed on both the upper and lower inner walls of the connecting sleeve 202. An annular limiting groove matching the sealing rings is provided on the outer wall of the water supply pipe fitting 2. The connecting sleeve 202 is movably connected to the packing layer 102. An insertion hole 107 for the connecting sleeve 202 to be accommodated is vertically provided at the center of the packing layer 102. Both ends of the connecting sleeve 202 penetrate the packing layer 102. On both the upper and lower surfaces of the packing layer 102, a water-retaining ring 210 is fixedly connected to the top of the connecting sleeve 202 above the packing layer 102. The water-retaining ring 210 is rotatably connected to the top surface of the packing layer 102, and a gap is left between the insertion hole 107 and the connecting sleeve 202. The upper scraper 3 is fixed to the connecting sleeve 202 and is located inside the tower body 1. When the connecting sleeve 202 rotates, it will rotate synchronously with the upper scraper 3. Multiple vertically fixed components are connected inside the opening 201. The scraper 203 abuts against the inner wall of the connecting sleeve 202. Specifically, the water supply pipe 2 is fixed inside the tower body 1. When the connecting sleeve 202 is driven to rotate, the gap reserved between the insertion hole 107 and the connecting sleeve 202 can prevent the connecting sleeve 202 from directly rubbing against the packing layer 102, thus avoiding the generation of additional heat from continuous friction. When the connecting sleeve 202 rotates, the water supply pipe 2 remains stationary. Although the position of the scraper 203 does not change, it can still clean and scrape away the scale on the inner wall of the entire connecting sleeve 202, reducing the scale residue inside the entire water supply pipe 2. The connecting sleeve 202 can also drive the upper scraper 3 to scrape off the water stains attached to the bottom surface of the packing layer 102, preventing some cooling water from adhering to the packing layer 102 for a long time and thus generating scale. The water baffle ring 210 can prevent the cooling water sprayed by the spray pipe 207 from falling directly down through the gap between the insertion hole 107 and the connecting sleeve 202.

[0036] In a further embodiment of the present invention, a transmission sleeve 204 is rotatably sleeved at the bottom of the water supply pipe 2, and the lower scraper 4 is fixed to the transmission sleeve 204. The lower scraper 4 is located in the chassis 104, and the bottom end of the transmission sleeve 204 and the bottom of the lower scraper 4 are in contact with the chassis 104 of the cooling tower. Specifically, when the transmission sleeve 204 rotates, it will drive the lower scraper 4 to scrape the water stains on the chassis 104, so that the water accumulated in the chassis 104 is scraped into the drain outlet, thus avoiding the problem of incomplete cooling water recovery.

[0037] In a further embodiment of the present invention, a driving component 7 is installed at the bottom of the tower body 1. The driving component 7 is connected to the transmission sleeve 204. The driving component 7 includes a driving motor 701 fixed at the bottom of the tower body 1. A driving gear 702 is installed inside the tower body 1 on the output shaft of the driving motor 701. A driven gear ring 211 that meshes with the driving gear 702 is fixedly sleeved on the outside of the transmission sleeve 204. A transmission bevel gear 205 is fixedly connected to one end of both the connecting sleeve 202 and the transmission sleeve 204. A connecting bevel gear 206 that meshes with the two transmission bevel gears 205 is rotatably installed on the water supply pipe fitting 2. Specifically, when the driving motor 701 is turned on to drive the driving gear 702 to rotate, the driving gear 702 then drives the transmission sleeve 204 to rotate. Since the connecting bevel gears 206 mesh with the connecting sleeve 202 and the transmission sleeve 204 respectively, When the transmission sleeve 204 rotates outside the water supply pipe 2, the transmission bevel gear 205 at its end drives the connecting bevel gear 206 to rotate. Then, the connecting bevel gear 206 drives the transmission bevel gear 205 on the connecting sleeve 202 to rotate, so that the connecting sleeve 202 and the transmission sleeve 204 rotate synchronously. The upper scraper 3 in the rotating state will scrape and clean the scale and residual water droplets on the bottom surface of the packing layer 102 to prevent the cooling water from adhering to the packing layer 102 for a long time. The lower scraper 4 in the rotating state can scrape the scale and residual cooling water on the bottom plate 104 of the tower body 1. The rotation directions of the upper scraper 3 and the lower scraper 4 are exactly opposite, thereby moving each grid cleaning component 5 back and forth in a certain area on the air inlet grid 101 to clean the scale and the attached cooling water on the grid plate.

[0038] Meanwhile, in existing technologies, a drive mechanism is typically added to directly drive the grille cleaning component 5, which then drives the grille cleaning component 5 to continuously move circumferentially across the entire air intake grille 101 to clean the grille. Although this solution can also remove scale from the grille, the centrifugal force generated by the grille cleaning component 5 will not disappear, easily causing the cooling water on the grille to be thrown out. This often results in the cooling tower needing to be replenished after running for a period of time. However, by using the cooperation of the upper scraper 3 and the lower scraper 4, the method of allowing each grille cleaning component 5 to move back and forth in a certain area of ​​the air intake grille 101 to remove scale will counteract the centrifugal force generated by the grille cleaning component 5, preventing water droplets attached to the grille from being thrown out of the cooling tower, and eliminating the need for frequent replenishment of cooling water.

[0039] In a further embodiment of the present invention, a shaft 212 fixed to a connecting bevel gear 206 is rotatably mounted inside the water supply pipe fitting 2. A filter screen 213 is also fixedly embedded inside the water supply pipe fitting 2, with the filter screen 213 located above the shaft 212. An impurity crushing assembly 9 is rotatably mounted at the bottom of the filter screen 213. The shaft 212 is connected to the impurity crushing assembly 9 via a transmission connection. The impurity crushing assembly 9 includes a connecting gear ring 901 rotatably connected to the bottom of the filter screen 213. A connecting gear 214 meshing with the connecting gear ring 901 is fixedly connected to the shaft 212. A scraper 902 abutting against the bottom surface of the filter screen 213 is installed inside the connecting gear ring 901. Multiple sets of crushing blades 903 are distributed in a ring at the bottom of the filter screen 213. The top of the scraper 902 has an opening for contact with the crushing blades. The blade 903 is matched with the blade groove 904. Specifically, the connecting bevel gear 206 is installed outside the water supply pipe 2 via the shaft 212. When the connecting bevel gear 206 is driven by the transmission bevel gear 205, it will drive the shaft 212 to rotate continuously. The connecting gear 214 on the shaft 212 will then drive the connecting gear ring 901 to rotate. As the water flows through the filter screen 213, the solid particles will be blocked below the filter screen 213 under the action of water pressure. At this time, the scraper 902 in the connecting gear ring 901 will scrape the particles and impurities towards the crushing blades 903. The crushing blades 903 are used to cut and crush the impurities in the cooling water until the impurities reach the required aperture of the filter screen 213, so as to avoid subsequent clogging of the spray pipe 207 and ensure the efficiency of heat exchange and cooling.

[0040] In a further embodiment of the present invention, the bar screen cleaning assembly 5 includes a connecting rod 501 slidably mounted on the inner wall of the tower body 1. Slider blocks 505 are mounted on both the upper and lower sides of one side of the connecting rod 501. Annular grooves 108 for sliding of the two sliders 505 are respectively provided on the inner wall of the tower body 1 and the inner wall of the chassis 104. A descaling scraper 502 is fixedly connected to one side of the connecting rod 501. The descaling scraper 502 has slots adapted to each bar screen on the air inlet bar screen 101. Each bar screen is located within the descaling scraper 502. In the slot, the descaling scraper 502 can contact each grid plate on the air inlet grille 101 respectively. Specifically, when the upper scraper 3 and the lower scraper 4 respectively move the grille cleaning assembly 5, the connecting rod 501 in the grille cleaning assembly 5 will move along the pre-opened annular slide groove 108 in the tower body 1, allowing the connecting rod 501 to move back and forth along the inner wall of the tower body 1, ensuring that the descaling scraper 502 can always contact the air inlet grille 101, so that the scale on the air inlet grille 101 is cleaned more thoroughly.

[0041] In a further embodiment of the present invention, a pair of elastic abutment members 503 are installed on the other side of the connecting rod 501. The pair of elastic abutment members 503 respectively abut against the upper scraper 3 and the lower scraper 4. The pair of elastic abutment members 503 are slidably connected to the top and bottom of the connecting rod 501, and a compression spring 504 is installed between the elastic abutment members 503 and the connecting rod 501. The opposite ends of the pair of elastic abutment members 503 are respectively provided with abutment grooves 506. The two abutment grooves 506 face opposite directions, respectively towards the rotation direction of the upper scraper 3 and the lower scraper 4. Specifically, when the upper scraper 3 rotates, it first abuts against the upper elastic abutment member 503, which will drive the connecting rod 501 to move a certain distance in the rotation direction of the upper scraper 3. When the connecting rod 501 is blocked by the support rod 105, the upper scraper 3 will squeeze... The elastic abutment 503 above the connecting rod 501 is pressed down, causing the elastic abutment 503 to move downward, thus allowing the upper scraper 3 to continue rotating to actuate the other grille cleaning assembly 5. When the upper scraper 3 rotates, the lower scraper 4, which rotates synchronously with it, will first abut against the elastic abutment 503 below the connecting rod 501, causing the connecting rod 501 to move back, blocked by the support rod 105, until the connecting rod 501 is blocked again by another support rod 105. At this time, the lower scraper 4 presses against the elastic abutment 503 below the connecting rod 501, forcing the elastic abutment 503 to move upward, allowing the lower scraper 4 to continue rotating. This allows the grille cleaning assembly 5 to continuously scrape water stains and scale back and forth on the air intake grille 101, and it is not necessary to adjust the direction of movement of the grille cleaning assembly 5 by adjusting the rotation of the output shaft of the drive motor 701 through the control system.

[0042] In a further embodiment of the present invention, a return water cavity 103 is provided at the bottom of the inner wall of the tower body 1, and a packing plate 109 is embedded in the return water cavity 103. Multiple water guide grooves 8 are annularly embedded on the outer wall of the transmission sleeve 204. The inner side of each water guide groove 8 is connected to the water supply pipe 2, and its top opening is larger than its bottom opening. The tops of the multiple water guide grooves 8 are fixedly connected to the same water collection tray 801, and the water guide grooves 8 are located between the packing layer 102 and the return water cavity 103. Specifically, during normal operation of the cooling tower, some of the cooled water that has completed heat exchange falls onto the water collection tray 801, and then flows from the water collection tray 801 into each water guide groove 8. When the cooled water enters the water guide groove 8, it will be guided by the water guide groove 8... The water comes into contact with the outer wall of the water supply pipe 2 and then slides down the outer wall of the water supply pipe into the return water chamber 103. This allows for pre-cooling of the water supply pipe 2 and initial cooling of the cooling water that is about to undergo heat exchange. This prevents the cooling water from becoming too hot after the treatment and improves the cooling circulation effect of the cooling tower. The water entering the return water chamber 103 passes through the packing plate 109 and is cooled by heat exchange. Then, the pump body 6 discharges the cooling water in the chassis 104 and the return water chamber 103 at the same time. The transmission sleeve 204 is in a state of continuous rotation. The cooling water that has absorbed heat in the water guide trough 8 can be quickly thrown into the return water chamber 103 under the action of centrifugal force.

[0043] In a further embodiment of the present invention, a connecting frame is installed between the lower scraper 4 and the transmission sleeve 204. The connecting frame is located above the return water chamber 103, and a cleaning brush is fixedly connected inside the connecting frame. Specifically, the lower scraper 4 is fixed together with the transmission sleeve 204 through the connecting frame. When the transmission sleeve 204 is driven by the driving component 7, the cleaning brush on the connecting frame continuously cleans the scale in the return water chamber 103, avoiding the inconvenience of cleaning after the scale has been stored for a long time.

[0044] In a further embodiment of the present invention, the top of the tower body 1 is open, and a heat exhaust fan 10 is installed in the open. Specifically, after the heat exhaust fan 10 is turned on, it will accelerate the airflow circulation in the tower body 1 and exhaust the hot airflow generated by the water during heat exchange, thereby accelerating the cooling effect.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
