Description

Technical Field

[0001] This utility model belongs to the field of air conditioning circulating water purification technology, and in particular relates to an air conditioning circulating water purification device. Background Technology

[0002] Air conditioning circulating water purification is a process of treating the cooling water or chilled water used in air conditioning systems. It removes suspended solids, dissolved salts, and harmful substances such as microorganisms through physical, chemical, or biological methods, controls scaling, corrosion, and algae growth in the water system, ensures efficient equipment operation, and extends the service life of the equipment.

[0003] Mechanical filters are commonly used in air conditioning circulating water systems to remove impurities from the water. Existing purification devices typically consist of a single filter cartridge, an inlet, and an outlet. Water flows through the filter screen embedded in the cartridge to trap impurities. However, this type of structure requires the system to be shut down and the entire filter cartridge to be disassembled when cleaning the filter screen, causing the system to be interrupted. Furthermore, the disassembly and assembly of the filter cartridge requires special tools, making the operation cumbersome and time-consuming. Maintenance is particularly difficult in confined machine rooms, which seriously affects the continuous operating efficiency of the air conditioning system and is not conducive to its use.

[0004] To address these issues, we offer an air conditioning circulating water purification device. Utility Model Content

[0005] The purpose of this utility model is to provide an air conditioning circulating water purification device. Through the cooperation of fully automatic cleaning components and water distribution mechanism, it solves the problem that existing air conditioning circulating water purification devices require shutdown for cleaning the filter screen, and the disassembly process is time-consuming and laborious, making it impossible to automatically perform maintenance without shutting down the machine.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an air conditioning circulating water purification device, comprising a base and a fully automatic cleaning assembly. Filter barrels are fixedly connected to both sides of the top of the base. A filter cartridge is installed inside the filter barrel, and a sealing cover is installed on the top of the filter barrel. A drain hose is connected to the top of the sealing cover. A water distribution mechanism is fixedly connected to the front of the base, and both sides of the rear of the water distribution mechanism are connected to the filter barrel. The fully automatic cleaning assembly includes a control housing. A drive mechanism is fixedly connected to the bottom of the inner cavity of the control housing. Control arms are fixedly connected to both sides of the top of the drive mechanism. The top of the control arms penetrates the control housing and is fixedly connected to a ring scraper. An electric push rod is fixedly connected to the front of the filter barrel, and the top of the output end of the electric push rod is fixedly connected to the sealing cover.

[0008] The present invention is further configured such that the water distribution mechanism includes a water distribution shell, the rear side of which is fixedly connected to the base, and water supply pipes are provided on both sides of the inner cavity of the water distribution shell. The rear side of the water supply pipes penetrates the water distribution shell and communicates with the filter bucket. Electric cylinders are fixedly connected to both sides of the top of the water distribution shell. The bottom of the output end of the electric cylinder penetrates the water distribution shell and is fixedly connected to a sealing plug. The water distribution shell facilitates the delivery of air conditioning circulating water to the inside of the water supply pipes. The water supply pipes are used to guide the circulating water into the filter bucket for filtration. The electric cylinders can control the height of the sealing plug. When one of the filter buckets needs to be cleaned, the sealing plug can be used to seal the water supply pipe to prevent circulating water from entering the filter bucket. The air conditioning circulating water purification operation can then continue through the other filter bucket.

[0009] The present invention is further configured such that a water injection pipe is connected to the front side of the water distribution shell, and a controller is fixedly connected to the right side of the front surface of the water distribution shell. The water injection pipe can transport air conditioning circulating water to the inside of the water distribution shell, and the controller is used to control the start and stop of the electric cylinder, electric push rod and drive mechanism.

[0010] The present invention is further configured such that the driving mechanism includes a motor, the bottom of the motor is fixedly connected to the inner wall of the control housing, a screw is fixedly connected to the right side of the output end of the motor, and threaded sleeves are threadedly connected to both sides of the surface of the screw. The top of the threaded sleeves is fixedly connected to the control arm. The motor can cooperate with the screw to control the two threaded sleeves to move simultaneously to the opposite side or the opposite side, so that the threaded sleeves can drive the annular scraper to fit against the surface of the filter cartridge through the control arm.

[0011] The present invention is further configured such that the threads on both sides of the screw surface are opposite, the left side of the screw is movably connected to the inner wall of the control housing via a bearing, and the top of the control housing has a movable opening for use with the control arm. The bearing can increase the stability of the screw during rotation, and the movable opening facilitates the adjustment of the left and right positions of the control arm driven by the threaded sleeve.

[0012] The present invention is further configured such that a slide rail is fixedly connected to the bottom of the inner cavity of the control shell, a slider is slidably connected to the surface of the slide rail, and the top of the slider is fixedly connected to the threaded sleeve. The slide rail and the slider can limit the threaded sleeve, improve its stability during movement, and prevent it from rotating during movement.

[0013] The present invention is further configured such that a one-way valve is installed on the surface of the drain hose, and a positioning sealing ring is fitted on the surface of the filter cartridge. The bottom of the positioning sealing ring is fixedly connected to the inner wall of the filter barrel. The one-way valve can prevent the purified circulating water from flowing back, and the positioning sealing ring can limit the filter cartridge so that it can be stably installed in the inner cavity of the filter barrel.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model utilizes a fully automatic cleaning component. The drive mechanism adjusts the control arm and the annular scraper to fit tightly against the surface of the filter cartridge. The electric push rod drives the sealing cover to move, causing the filter cartridge to shift inside the filter barrel. The annular scraper automatically removes impurities attached to the surface of the filter cartridge. There is no need for manual disassembly of the filter cartridge for cleaning and maintenance. This solves the problem that existing purification devices require tools to disassemble the filter screen for cleaning, reducing the time and difficulty of maintenance operations. It is suitable for machine room environments with limited space, making maintenance more convenient and ensuring long-term efficient operation of the equipment.

[0016] 2. This utility model uses a water distribution mechanism to receive air conditioning circulating water and distribute it to water supply pipes on both sides. An electric cylinder controls the lifting and lowering of a sealing plug to seal or open the water supply pipe. When one of the filter barrels needs cleaning, the sealing plug closes the corresponding water supply pipe, stopping the water supply to that filter barrel, while the other filter barrel continues to receive water flow through the water supply pipe for filtration. The controller coordinates the start and stop of the electric cylinder and the electric push rod to realize the alternating work and cleaning of the two filter barrels, ensuring that the air conditioning circulating water purification process is continuous and that there is no need to shut down the entire system during cleaning, thus improving the stability of system operation.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model is an air conditioning circulating water purification device, including a base 1 and a fully automatic cleaning component 7. Filter barrels 2 are fixedly connected to both sides of the top of the base 1. Filter cylinders 3 are provided inside the cavity of the filter barrel 2. A sealing cover 4 is provided on the top of the filter barrel 2. A drain hose 5 is connected to the top of the sealing cover 4. A water distribution mechanism 6 is fixedly connected to the front side of the base 1. Both sides of the rear side of the water distribution mechanism 6 are connected to the filter barrel 2. The fully automatic cleaning component 7 includes a control shell 71. A drive mechanism 72 is fixedly connected to the bottom of the cavity of the control shell 71. Control arms 73 are fixedly connected to both sides of the top of the drive mechanism 72. The top of the control arm 73 penetrates the control shell 71 and is fixedly connected to a ring scraper 74. An electric push rod 75 is fixedly connected to the front side of the filter barrel 2. The top of the output end of the electric push rod 75 is fixedly connected to the sealing cover 4.

[0027] Specifically: Filter cartridge 2 works with filter cylinder 3 to filter impurities in the air conditioning circulating water. The circulating water passes through micropores on the surface of filter cylinder 3, while impurities are retained on the surface of filter cylinder 3. The filtered circulating water is inside filter cylinder 3 and discharged from filter cartridge 2 through drain hose 5. Water distribution mechanism 6 can transport the circulating water to be purified to the inside of filter cartridge 2. Water supply to one of the filter cylinders 3 is stopped when automatic cleaning is required. Control housing 71 facilitates the installation and fixation of drive mechanism 72. Drive mechanism 72 can control the movement of two control arms 73 and annular scraper 74. The scraper 74 can fit against the surface of the filter cartridge 3. The filter cartridge 3 is driven to reset by the electric push rod 75, which can scrape off the impurities attached to the surface of the filter cartridge 3 and automatically complete the surface cleaning of the filter cartridge 3. There is no need for the staff to manually remove the filter cartridge 3 for cleaning. At the same time, the water distribution mechanism 6 controls the water supply to the two filter tanks 2. When the filter cartridge 3 in one filter tank 2 is being cleaned, the water supply to it is stopped, while the other filter tank 2 continues to perform normal circulating water filtration. The two filter tanks 2 alternately complete the cleaning operation, realizing the automatic cleaning and maintenance of the filter cartridge 3 without stopping the machine.

[0028] Example 2

[0029] Please see Figure 1-5Based on Embodiment 1, the water distribution mechanism 6 includes a water distribution shell 61. The rear side of the water distribution shell 61 is fixedly connected to the base 1. Water supply pipes 62 are provided on both sides of the inner cavity of the water distribution shell 61. The rear side of the water supply pipes 62 passes through the water distribution shell 61 and communicates with the filter bucket 2. Electric cylinders 63 are fixedly connected to both sides of the top of the water distribution shell 61. The bottom of the output end of the electric cylinder 63 passes through the water distribution shell 61 and is fixedly connected to a sealing plug 64. A water injection pipe is connected to the front side of the water distribution shell 61. A controller is fixedly connected to the right side of the front surface of the water distribution shell 61. The drive mechanism 72 includes a motor 721. The bottom of the motor 721 is fixedly connected to the inner wall of the control shell 71. The right side of the output end of the motor 721 is fixedly connected to the control shell 71. A screw 722 is connected, and threaded sleeves 723 are threadedly connected to both sides of the surface of the screw 722. The top of the threaded sleeves 723 is fixedly connected to the control arm 73. The threads on both sides of the surface of the screw 722 are opposite. The left side of the screw 722 is movably connected to the inner wall of the control housing 71 through a bearing. The top of the control housing 71 has an opening for use with the control arm 73. A slide rail is fixedly connected to the bottom of the inner cavity of the control housing 71. A slider is slidably connected to the surface of the slide rail. The top of the slider is fixedly connected to the threaded sleeve 723. A one-way valve 8 is installed on the surface of the drain hose 5. A positioning sealing ring 9 is fitted on the surface of the filter cartridge 3. The bottom of the positioning sealing ring 9 is fixedly connected to the inner wall of the filter barrel 2.

[0030] Specifically: the water distribution shell 61 facilitates the delivery of air conditioning circulating water to the water supply pipe 62, which in turn guides the circulating water into the filter canister 2 for filtration. The electric cylinder 63 controls the height of the sealing plug 64. When one of the filter canisters 2 needs cleaning, the sealing plug 64 can be used to seal the water supply pipe 62, preventing circulating water from entering the filter canister 2. The air conditioning circulating water purification operation continues through the other filter canister 2. The water injection pipe delivers air conditioning circulating water to the water distribution shell 61. The controller controls the start and stop of the electric cylinder 63, the electric push rod 75, and the drive mechanism 72. The motor 721 works in conjunction with the screw 722. The two threaded sleeves 723 are controlled to move simultaneously to opposite sides, so that the threaded sleeves 723 can drive the annular scraper 74 to fit against the surface of the filter cartridge 3 through the control arm 73. The bearing can increase the stability of the screw 722 during rotation. The movable opening facilitates the adjustment of the left and right positions of the threaded sleeves 723 to drive the control arm 73. The slide rail and slider can limit the threaded sleeves 723, improve their stability during movement, and prevent them from rotating during movement. The one-way valve 8 can prevent the backflow of purified circulating water. The positioning sealing ring 9 can limit the filter cartridge 3, so that it can be stably installed in the inner cavity of the filter barrel 2.

[0031] The working principle of this utility model is as follows: Air conditioning circulating water enters the water distribution shell 61 through the water injection pipe. The water distribution shell 61 evenly distributes the water flow to the two water supply pipes 62 on both sides. The water supply pipes 62 guide the water into the inner cavity of the filter barrel 2. The water flows through the micropores on the surface of the filter barrel 3, and impurities are trapped on the outside of the filter barrel 3. The filtered water enters the inside of the filter barrel 3 and is discharged through the drain hose 5. During normal operation, both filter barrels 2 work simultaneously. When impurities accumulate on the surface of the filter barrel 3 and need to be cleaned, the controller controls one of the electric cylinders 63 to drive the sealing plug 64 to descend, sealing one of the water supply pipes 62 and stopping the water supply to that filter barrel 2. At the same time, the electric push rod 75 drives the sealing cover 4 to rise, closing the filter barrel. 3 is lifted to the top of filter cartridge 2, then motor 721 drives screw 722 to rotate. The reverse thread on the surface of screw 722 drives the threaded sleeves 723 on both sides to move in opposite directions. The threaded sleeves 723 push the annular scraper 74 to fit against the surface of filter cartridge 3 through control arm 73. Electric push rod 75 drives sealing cover 4 to descend, and filter cartridge 3 returns to its original position in filter cartridge 2. The annular scraper 74 scrapes off surface impurities, automatically completing the surface cleaning of filter cartridge 3. During the cleaning process, another filter cartridge 2 continues to receive water flow from water supply pipe 62 for filtration, ensuring that the system does not stop. The entire process does not require manual disassembly of parts, making maintenance more convenient and ensuring long-term efficient operation of the equipment.
