Description

Technical Field

[0001] This utility model relates to the field of cooling tower equipment technology, specifically to an air inlet structure for a rotating and switching cooling tower. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and release it into the atmosphere. It achieves cooling of the circulating water through heat exchange between the water and the air. The most common applications of cooling towers are air conditioning, refrigeration, and the plastics and chemical industries.

[0003] However, existing cooling towers generally do not have filter components in their air intake structure, or they are equipped with conventional air intake filter equipment. However, after a period of use, the filter equipment can only be disassembled and replaced for cleaning and maintenance, which is cumbersome and delays the normal use of the cooling tower.

[0004] For example, the aforementioned problem exists in patent (CN222670829U); it describes "the air inlet structure of a cooling tower, the key technical points of which include a support base, the top of which is bolted to a fiberglass cooling tower body, a ladder frame bolted to the front of the support base, an air inlet assembly bolted to the left side of the fiberglass cooling tower body, and an mounting bracket bolted to the top of the fiberglass cooling tower body. The user bolts the fan body to the bottom of the connecting pipe, and the operation of the fan body blows air from its top air outlet, guiding the air into the interior of the fiberglass cooling tower body. At the same time, it works in conjunction with the operation of the fan of the fiberglass cooling tower body itself to quickly blow out the heat." The air inlet structure of the cooling tower in the above patent does not have a filtration device, requiring the use of conventional air inlet filtration equipment. After a period of use, it can only be disassembled and replaced for cleaning and maintenance, which is cumbersome and delays the normal use of the cooling tower.

[0005] To address the issue that cooling towers typically lack filtration components in their air intake structure, or are equipped with conventional air intake filtration equipment, which requires disassembly and replacement for cleaning and maintenance after a period of use, making the operation cumbersome and disrupting the normal operation of the cooling tower, we propose a rotating switching air intake structure for cooling towers. Utility Model Content

[0006] The purpose of this invention is to provide an air intake structure for a rotating and switching cooling tower to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an air inlet structure for a rotating and switching cleaning cooling tower, including an air inlet duct, a rotatably connected filter assembly inside the air inlet duct, a cleaning assembly inside the air inlet duct, a storage compartment below the cleaning assembly at the bottom of the air inlet duct, the filter assembly including a support plate, a plurality of filter cylinders vertically arranged from the inside to the outside at the bottom of the support plate, the cleaning assembly including a fixing plate, a cleaning mechanism matching the filter cylinders vertically arranged at the top of the fixing plate, a material discharge assembly between the storage compartment and the fixing plate, a rotation drive mechanism for the support plate at the top of the air inlet duct, and a plurality of baffles on the surface of the filter cylinders.

[0008] Furthermore, the material feeding assembly includes a feeding tray and several first arc-shaped feeding ports. The first arc-shaped feeding ports are located on the top of the fixed tray and are in contact with the outer wall of the cleaning mechanism. The top of the feeding tray is provided with a second arc-shaped feeding port that matches the first arc-shaped feeding port.

[0009] Furthermore, a support rod is vertically provided at the top center of the material discharge tray, the top of the support rod is fixedly connected to the bottom of the support tray, the first arc-shaped material discharge port and the second arc-shaped material discharge port are staggered, and the top of the material discharge tray is attached to the bottom of the fixed tray.

[0010] Furthermore, the material discharge tray is rotatably mounted on the top of the inner side of the storage compartment, and a compartment door is hinged to the outer wall of the storage compartment.

[0011] Furthermore, the cleaning mechanism includes several vertically arranged support plates, and the support plates (with a brush on the outer wall near the filter cylinder) have the first arc-shaped discharge port located on one side of the support plate.

[0012] Furthermore, the support plates are respectively located on the inner and outer sides of the filter cylinder, and brushes are provided on both sides of the outer wall of the support plate located between two adjacent filter cylinders.

[0013] Furthermore, an air inlet is provided on one side of the outer wall of the air inlet duct, and an air outlet is provided on the other side of the outer wall of the air inlet duct. The air inlet and air outlet are arranged in a straight line, and the support plates are arranged in a straight line. The straight line of the support plates is perpendicular to the straight line of the air inlet and air outlet.

[0014] Furthermore, the rotary drive mechanism includes a servo motor and a reducer, both of which are located at the top of the air inlet duct. The output shaft of the servo motor is connected to the input end of the reducer, and the output end of the reducer is connected to the center of the top of the support plate.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are: This invention comprises an air inlet duct, a filter assembly, a cleaning assembly, a storage bin, a cleaning mechanism, a support plate, and a filter cartridge. The storage bin collects dust and impurities washed off by the cleaning assembly. The cleaning mechanism cleans the filter assembly. The support plate supports the filter cartridge, ensuring its movement and adjustment. The filter cartridge filters the air. A material discharge assembly guides the material between the fixed plate and the storage bin, allowing dust and impurities scraped off the filter cartridge to enter the storage bin. The storage bin is also sealed to prevent air from entering during cooling tower intake, ensuring effective collection. A rotary drive mechanism rotates the filter cartridge, and the cleaning mechanism directly cleans the filter cartridge surface, scraping off dust and impurities. This effectively achieves rotary cleaning of the filter cartridge. Furthermore, the rotation of the filter cartridge allows for switching of the filter surface, significantly improving the filtration efficiency of the air inlet structure.

[0016] In this invention, the material feeding assembly includes a feeding disc, a first arc-shaped feeding port, and a second arc-shaped feeding port. When the support disc and filter cylinder rotate, the feeding disc rotates along with them, allowing the scraped dust and impurities to enter the collection chamber through the first and second arc-shaped feeding ports for collection. By adjusting the relative positions of the first and second arc-shaped feeding ports, the opening and closing of the feeding channel can be effectively achieved. The support plate and baffle in the cleaning mechanism work together to provide baffle support to the inner and outer sides of the filter cylinder, effectively sealing the gaps between adjacent filter cylinders. This ensures that air must pass through multiple filter cylinders sequentially before exiting, preventing air from being directly discharged from the outermost large-aperture filter cylinder and ensuring effective air filtration.

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. Example

[0019] Please see Figures 1-5 This utility model provides a technical solution: an air intake structure for a rotating and switching cleaning cooling tower, including an air intake duct 1, a rotatably connected filter assembly 2 inside the air intake duct 1, a cleaning assembly 3 inside the air intake duct 1, a storage compartment 4 below the cleaning assembly 3 at the bottom of the air intake duct 1, the filter assembly 2 including a support plate 201, a plurality of filter cylinders 202 vertically arranged from the inside to the outside at the bottom of the support plate 201, the cleaning assembly 3 including a fixing plate 301, a cleaning mechanism 5 matching the filter cylinders 202 vertically arranged at the top of the fixing plate 301, a material discharge assembly between the storage compartment 4 and the fixing plate 301, a rotation drive mechanism 6 for the support plate 201 at the top of the air intake duct 1; the material discharge plate 204 is rotatably disposed on the top of the inner side of the storage compartment 4, a compartment door 401 is hinged to the outer wall of the storage compartment 4; an air inlet 101 is provided on one side of the outer wall of the air intake duct 1, and an air outlet 102 is provided on the other side of the outer wall of the air intake duct 1.

[0020] In one embodiment, the rotary drive mechanism 6 includes a servo motor 601 and a reducer 602. Both the servo motor 601 and the reducer 602 are located at the top of the air inlet duct 1. The output shaft of the servo motor 601 is connected to the input end of the reducer 602, and the output end of the reducer 602 is connected to the top center of the support plate 201. When the rotary drive mechanism 6 is working, the servo motor 601 can drive the support plate 201 to rotate through the reducer 602. The support plate 201 drives the filter cartridge 202 and the discharge plate 204 to rotate and adjust, which can effectively ensure the rotational switching and cleaning of the filter cartridge 202.

[0021] The working principle of this utility model: Refer to the instruction manual appendix Figures 1-5 This utility model comprises an air inlet duct 1, a filter assembly 2, a cleaning assembly 3, a storage chamber 4, a cleaning mechanism 5, a support plate 201, and a filter cylinder 202. The air inlet duct 1 acts as an air intake filter at the air inlet of the cooling tower, effectively filtering the incoming air. The filter assembly 2 filters the incoming air inside the air inlet duct 1. The cleaning assembly 3 cleans the filter assembly 2. The storage chamber 4 collects the dust and impurities washed off by the cleaning assembly. The cleaning mechanism 5 performs the cleaning operation on the filter assembly 2. The support plate 201... The filter cartridge 202 is supported to ensure that it can move and adjust with the support plate 201. The filter cartridge 202 filters the air. The fixed plate 301 provides fixed support for the cleaning mechanism 301 to ensure its stability. The material feeding component guides the material feeding between the fixed plate 301 and the collection bin 4, so that the dust and impurities scraped off the filter cartridge 202 enter the collection bin 4 for collection. At the same time, the collection bin 4 is sealed to prevent air from entering the collection bin 4 when the cooling tower is being supplied with air, thus ensuring the effective collection and processing of the material. The rotary drive mechanism 6 can drive the support plate 201 to rotate, and the support plate 201 can drive the filter cartridge 202 to rotate. The filter cartridge 202 and the cleaning mechanism 5 are in contact and interleaved, so that when the filter cartridge 202 rotates, the cleaning mechanism 5 directly cleans the surface of the filter cartridge 202, scraping off dust and impurities from the surface of the filter cartridge 202. This can effectively achieve the rotational cleaning of the filter cartridge 202. At the same time, the rotation of the filter cartridge 202 can switch the filter surface of the filter cartridge 202, which can effectively improve the filtration effect of the air intake structure. The door 401 is hinged to the outer wall of the storage compartment 4, which can enable the storage compartment 4 to be opened and closed quickly, making it easy to clean and collect the dust and impurities inside the storage compartment 4. Outside air enters the air inlet 1 through the air inlet 101, and after being processed by the filter component 2, it is discharged from the air outlet 102 into the cooling tower. Example

[0022] Please see Figures 2-5This utility model provides a technical solution: an air inlet structure for a rotating and switching cleaning cooling tower, wherein the material discharge assembly includes a material discharge plate 204 and a plurality of first arc-shaped material discharge ports 302. The first arc-shaped material discharge ports 302 are located on the top of a fixed plate 301 and are in contact with the outer wall of the cleaning mechanism 5. The top of the material discharge plate 204 has a second arc-shaped material discharge port 205 that matches the first arc-shaped material discharge ports 302. A support rod 203 is vertically provided at the top center of the material discharge plate 204. The top of the support rod 203 is fixedly connected to the bottom of the support plate 201. The first arc-shaped material discharge ports 302 and the second arc-shaped material discharge ports 205 are staggered. The top of the material discharge plate 204 is connected to the fixed plate 301. 1. Bottom fit; The cleaning mechanism 5 includes several vertically arranged support plates 501. The outer wall of the support plate 501 is provided with a brush 502 near the filter cylinder 202. The first arc-shaped discharge port 302 is provided on one side of the support plate 501. The support plates 501 are respectively provided on the inner and outer sides of the filter cylinder 202. Brushes 502 are provided on both sides of the outer wall of the support plate 501 between two adjacent filter cylinders 202. The air inlet 101 and the air outlet 102 are arranged in a straight line. The support plates 501 are arranged in a straight line. The straight line of the distribution of the support plates 501 is perpendicular to the straight line of the distribution of the air inlet 101 and the air outlet 102. The surface of the filter cylinder 202 is provided with several baffles 206.

[0023] The working principle of this utility model: Refer to the instruction manual appendix Figures 2-5 This utility model includes a material feeding assembly comprising a feeding tray 204, a first arc-shaped feeding port 302, and a second arc-shaped feeding port 205. The first arc-shaped feeding port 302 has an opening at the top of the fixed tray 301. The feeding tray 204 is fixedly connected to the support tray 201 via a support rod 203. When the support tray 201 and the filter cylinder 202 rotate, the feeding tray 204 rotates along with the support tray 201 and the filter cylinder 202. The second arc-shaped feeding port 205 has an opening at the top of the feeding tray 204, allowing the scraped dust and impurities to enter the storage bin 4 for collection through the first arc-shaped feeding port 302 and the second arc-shaped feeding port 205. The first arc-shaped discharge port 302 and the second arc-shaped discharge port 205 are staggered. By rotating and adjusting the relative positions of the first arc-shaped discharge port 302 and the second arc-shaped discharge port 205, the falling channel can be effectively opened and closed. When the first arc-shaped discharge port 302 and the second arc-shaped discharge port 205 are completely staggered, the falling channel for dust and impurities is closed, and neither dust and impurities nor air can enter the inside of the storage chamber 4. When the first arc-shaped discharge port 302 and the second arc-shaped discharge port 205 intersect, the falling channel for dust and impurities is open, and dust and impurities can pass through the falling channel and enter the inside of the storage chamber 4. Multiple filter cartridges 202 are arranged sequentially from the inside to the outside, and the aperture of the multiple filter cartridges 202 increases sequentially from the inside to the outside. The support plate 501 and baffle 206 in the cleaning mechanism 5 can cooperate to provide baffle support for the inner and outer sides of the filter cartridges 202, which can effectively ensure that the gaps between adjacent filter cartridges 202 are sealed, ensuring that air must pass through multiple filter cartridges 202 in sequence before exiting, avoiding air from being directly discharged from the outermost large aperture filter cartridge 202, and ensuring the air filtration effect. As the filter cartridge 202 rotates, the brush 502 on the outer wall of the support plate 501 cleans the dust and impurities on the surface of the filter cartridge 202. The dust and impurities scraped off the surface of the filter cartridge 202 fall directly into the inner side of the first arc-shaped discharge port 302 and onto the top of the discharge plate 204. As the discharge plate 204 rotates, the second arc-shaped discharge port 205 rotates to the position where it intersects with the first arc-shaped discharge port 302. The dust and impurities fall from the second arc-shaped discharge port 205 into the storage compartment 4 for collection. The distribution positions of the air inlet 101, air outlet 102, and support plate 501 are set so that the support plate 501 and the baffle 206 cooperate to block and separate the filter cartridge 202 between the air inlet 101 and the air outlet 102. This can effectively ensure that after the outside air enters the air inlet 1 through the air inlet 1, the air must pass through multiple filter cartridges 202 in sequence before it can be discharged from the air outlet 102, thus ensuring the air filtration effect.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
