Description

Technical Field

[0001] This utility model relates to the technical field of water supply equipment, specifically to an energy-saving variable frequency constant pressure water supply equipment. Background Technology

[0002] Constant pressure variable frequency water supply equipment connects directly to the municipal water supply network without causing any side effects to the municipal network. It is an ideal and energy-saving secondary water supply equipment, and also has many advantages such as being fully enclosed, pollution-free, small in size, reliable in operation, and easy to maintain.

[0003] According to Chinese patent number CN 223119166 U, an energy-saving fully automatic variable frequency constant pressure water supply device is disclosed, comprising a pressure tank. The pressure tank has an inlet flange fixedly installed at its top and an outlet pipe fixedly installed at its bottom. An extension pipe is fixedly installed at one end of the outlet pipe, and multiple water pumps are installed on one side of the pressure tank. This invention, by setting up a pressure tank and water pumps in series, allows the water pumps to pressurize the water in the pressure tank during water supply, ensuring a constant water pressure in the pipeline network. By installing a filter screen inside the pressure tank with a "C"-shaped structure, impurities can be collected inside the filter screen during water filtration, facilitating disassembly and cleaning. Furthermore, the "C"-shaped structure prevents impurities from falling off during filter screen disassembly, thus preventing the disassembly of the filter screen from affecting the water quality inside the equipment.

[0004] However, existing variable frequency constant pressure water supply equipment improves water quality by using a filter screen inside the pressure tank to collect impurities during transport. The filter screen can be easily cleaned by removing it via bolts on the movable base. However, in actual use, the equipment is directly connected to the municipal water supply pipeline via the inlet pipe, but lacks a structure to adapt to changes in the municipal pipeline's pressure. This makes it difficult to control the water pressure entering the inlet pipe, resulting in unstable outlet pressure. Furthermore, municipal pipelines are usually buried underground, and impurities can easily accumulate within them over time, or leaks can introduce impurities. Consequently, the water entering the inlet pipe already carries impurities. Without filtration, this inevitably affects the lifespan of the variable frequency constant pressure water supply equipment. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the fact that existing variable frequency constant pressure water supply equipment cannot stabilize the water supply in real time according to the water supply pressure of the municipal pipeline, and at the same time, the water source before entering the water inlet pipe is not filtered, which easily affects the use of the variable frequency constant pressure water supply equipment.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] An energy-saving variable frequency constant pressure water supply device includes a base and an inlet pipe fixed on its top. The inlet pipe has a connecting pipe at its input end and a pressure relief tank at its other end. Two manual valves, both communicating with the pressure relief tank, are connected to the top of the pressure relief tank. Each of the two manual valves has a filter channel at its input end. A sealing seat is bolted to the top of each of the two filter channels. A drive mechanism is shared inside the two sealing seats. A filter frame is placed between the filter channels and the sealing seats. Each of the two filter frames has one or more filter plates threaded from top to bottom inside. A follower column is rotatably connected to the bottom of each of the two filter frames. Matching cleaning brushes are provided on the top of each of the two filter plates. Both cleaning brushes are threaded to the follower column. The drive mechanism passes through the sealing seat and is connected to the follower column, driving the follower column and cleaning brushes to rotate and clean. A sealing cylinder is installed on the top of the pressure relief tank. A matching induction float is provided at the lower end of the sealing cylinder. A lifting mechanism is provided on the top of the induction float.

[0008] As a preferred technical solution of this utility model, an input pipe is connected to one side of both filter channels. A control valve is provided at the end of the input pipe near the corresponding filter channel. The input ends of the two control valves are connected to a delivery pipe, which, together with the manual valve, enables the cleaning of the filter plate in a separate channel.

[0009] As a preferred embodiment of the present invention, the driving mechanism includes driving shafts that are rotatably installed inside the sealing seat, and the lower ends of the two driving shafts are connected to driving heads, with the lower ends of the two driving heads respectively inserted into the interior of the corresponding follower column.

[0010] As a preferred embodiment of the present invention, the driving mechanism further includes driving wheels that are respectively fixedly installed on the outer side walls of the corresponding driving shafts. The outer side walls of the two driving wheels are connected to a gear belt for transmission, which drives the two driving shafts to rotate together.

[0011] As a preferred embodiment of this utility model, the lifting mechanism includes a drive cylinder rotatably installed inside the sealing cylinder. The upper end of the drive cylinder passes through the sealing cylinder and is connected to a drive motor. A lifting rod is threadedly connected inside the drive cylinder. The lifting rod is connected to a sliding rod on the inner wall of the sealing cylinder. Rotating the drive cylinder controls the lifting rod to move vertically up and down. The lower end of the lifting rod passes through the drive cylinder and is connected to an induction float.

[0012] As a preferred technical solution of this utility model, a sealing ring platform matching the outer wall of the induction float is connected to the outer wall of the sealing cylinder near the lower opening inside the pressure relief tank. The outer wall of the induction float is provided with a sealing membrane to enhance the sealing performance in contact with the sealing ring platform.

[0013] As a preferred embodiment of this utility model, a support base is installed at the lower part of the pressure relief tank, and the support base is detachably installed on the top of the base. A sealing ring is provided on the top of the filter frame to enhance the sealing performance.

[0014] The beneficial effects of this utility model are as follows:

[0015] Beneficial effect 1

[0016] This utility model can initially buffer the pressure of the water source entering the equipment by setting up a pressure relief tank. The induction float adjusts its position in real time according to the changes in the water level in the pressure relief tank. The opening and closing of the sealing cylinder is controlled by the lifting mechanism, thereby achieving a constant pressure between the tank and the outside. This structural design enables the water supply equipment to adapt to changes in the water supply pressure of the municipal pipeline, ensures the stability of the outlet water pressure, and improves the reliability and stability of the water supply system.

[0017] Beneficial effect two

[0018] This invention effectively solves the problem in existing variable frequency constant pressure water supply equipment where the water source is not filtered before entering the inlet pipe, which can easily affect the equipment's service life. In existing technology, impurities from municipal pipelines may mix into the water source, damaging the internal structure of the water supply equipment and reducing its lifespan. This invention, however, sets up a filter channel and filter frame at the front end of the inlet pipe. Multiple filter plates are threaded together from top to bottom within the filter frame, pre-filtering the water source before it enters the equipment and effectively removing impurities. Simultaneously, each filter plate has a matching cleaning brush at its top. A drive mechanism rotates the follower column and cleaning brush to clean the filter plates, preventing clogging and further ensuring the normal operation of the water supply equipment and extending its service life.

[0029] Example 1

[0030] exist Figures 1-4 This utility model provides a technical solution: an energy-saving variable frequency constant pressure water supply device, including a base 1 and an inlet pipe 2 fixed on its top. The inlet pipe 2 is connected to a connecting pipe 3 at its input end, and the other end of the connecting pipe 3 is connected to a pressure relief tank 4. The top of the pressure relief tank 4 is connected to two manual valves 5, both of which are connected to the pressure relief tank 4. The input ends of the two manual valves 5 are connected to filter channels 6. The tops of the two filter channels 6 are bolted to sealing seats 7. The two sealing seats 7 are equipped with a common driving mechanism. It should be noted that the driving mechanism is usually driven by a motor. A filter frame 11 is provided between the filter channels 6 and the sealing seats 7. The interior of the two filter frames 11 is self-contained. Each filter plate 12 is threadedly connected from top to bottom. The bottom of each of the two filter frames 11 is rotatably connected to a follower column 13. The top of each of the two filter plates 12 is provided with a matching cleaning brush 14. Both cleaning brushes 14 are threadedly connected to the follower column 13. The drive mechanism passes through the sealing seat 7 and is connected to the follower column 13. It drives the follower column 13 and the cleaning brush 14 to rotate and clean. The multiple filter plates 12 can pre-filter water before it enters the equipment. At the same time, each filter plate is provided with a matching cleaning brush 14 on one side. The follower column 13 is driven by a motor to drive the threaded cleaning brush 14 to clean the impurities on the filter plate 12 to prevent clogging and improve the service life of the equipment.

[0031] A sealing cylinder 19 is installed on the top of the pressure relief tank 4. A matching induction float 22 is provided at the lower end of the sealing cylinder 19. A lifting mechanism is provided on the top of the induction float 22. The induction float 22 senses the water supply situation inside the pressure relief tank 4 in real time. When the water supply is sufficient, the lifting mechanism controls the induction float to move upward and block the sealing cylinder 19. Conversely, when the municipal water supply is insufficient, the induction float moves downward. The sealing cylinder 19 controls the pressure inside the tank to be constant with the outside pressure, thereby controlling the water supply to be constant.

[0032] In one aspect of this embodiment, an input pipe 10 is connected to one side of both filter channels 6. A control valve 17 is provided at the end of the input pipe 10 near the corresponding filter channel 6. The input ends of the two control valves 17 are connected to a delivery pipe. With the help of the manual valve 5, the filter plate 12 can be cleaned in a separate channel. At the same time, the control valve 17 and the manual valve 5 on one side can be closed to clean the filter plate 12 in the corresponding channel. Before cleaning, the bolts connecting the filter channel 6 and the sealing seat 7 can be removed. The other filter channel continues to deliver water without the need to stop the equipment.

[0033] In one aspect of this embodiment, the drive mechanism includes drive shafts 8 rotatably mounted inside the sealing seat 7. The lower ends of the two drive shafts 8 are connected to drive heads 15. The lower ends of the two drive heads 15 are respectively inserted into the interior of the corresponding follower column 13. The drive mechanism also includes drive wheels 9 fixedly mounted on the outer walls of the corresponding drive shafts 8. The outer walls of the two drive wheels 9 are connected to a gear belt for transmission, which drives the two drive shafts 8 to rotate together.

[0034] In one aspect of this embodiment, the lifting mechanism includes a drive cylinder 20 rotatably installed inside the sealing cylinder 19. The upper end of the drive cylinder 20 passes through the sealing cylinder 19 and is connected to a drive motor 18. A lifting rod 21 is threadedly connected inside the drive cylinder 20. The lifting rod 21 is connected to a sliding rod on the inner wall of the sealing cylinder 19. Rotating the drive cylinder 20 controls the lifting rod 21 to move vertically up and down. The lower end of the lifting rod 21 passes through the drive cylinder 20 and is connected to an induction float 22.

[0035] A sealing ring platform 23, which matches the outer wall of the induction float 22, is connected to the outer wall of the sealing cylinder 19 near the lower opening inside the pressure relief tank 4. The outer wall of the induction float 22 is provided with a sealing membrane to enhance the sealing performance in contact with the sealing ring platform 23.

[0036] In one aspect of this embodiment, a support base 24 is installed at the lower part of the pressure relief tank 4 to support the pressure relief pipe 4 stably. The support base 24 is detachably installed on the top of the base 1. A sealing ring 16 is provided on the top of the filter frame 11 to enhance the sealing performance.

[0037] The working principle of this utility model is as follows: In actual operation, firstly, the water inlet pipe 2 of the equipment is connected to the pressure relief tank 4 through the connecting pipe 3. The pressure relief tank 4 can initially buffer the pressure of the water entering the equipment, effectively reducing the impact of municipal water supply pressure fluctuations on the operation of the equipment. When the municipal water supply pressure is too high, the sensing float 22 in the pressure relief tank 4 will move upward according to the rise in water level. The lifting mechanism controls the sensing float 22 to block the sealing cylinder 19, preventing excessive pressure from damaging subsequent equipment. When the municipal water supply pressure is insufficient, the sensing float 22 moves downward, and the sealing cylinder 19 opens, ensuring that the pressure inside the tank is constant with the outside pressure, thereby achieving stable water supply.

[0038] Meanwhile, before the water source enters the pressure relief tank 4, it first passes through two filtration channels 6. Each filtration channel 6 is equipped with a filter frame 11, and multiple filter plates 12 are threadedly connected from top to bottom inside the filter frame 11. These filter plates 12 can pre-filter the water source, effectively remove impurities, and ensure the water quality entering the equipment. At the same time, each filter plate 12 is equipped with a matching cleaning brush 14 at its top. The cleaning brush 14 is threadedly connected to the follower column 13. The follower column 13 is driven to rotate by the drive mechanism, which in turn drives the cleaning brush 14 to clean the filter plate 12, preventing the filter plate from clogging and extending the service life of the filter plate. In addition, the equipment is also designed with a separate channel cleaning function. Through the cooperation of the control valve 17 and the manual valve 5, the filter plate 12 in a single channel can be cleaned without stopping the machine, which improves the maintenance efficiency of the equipment.

[0039] In summary, the energy-saving variable frequency constant pressure water supply equipment of this utility model has significant advantages. First, through the cooperation of the pressure relief tank 4 and the induction float 22, it can adapt to changes in the municipal pipeline water supply pressure in real time, ensuring stable water pressure and solving the problem of unstable water supply caused by pressure fluctuations in existing technologies. Second, the multi-layer filter plate 12 in the filter channel 6 and the automatic cleaning function not only improve water quality but also effectively prevent filter plate clogging, extend the service life of the equipment, and avoid the impact on the internal water quality caused by frequent disassembly and cleaning of the filter screen. In addition, the design of separate channel cleaning allows the equipment to be maintained without stopping the machine, further improving the continuity and reliability of water supply. These innovative designs make the water supply equipment of this utility model superior to existing technologies in terms of energy saving, high efficiency, and stability, and it has broad application prospects.
