Description

Technical Field

[0001] This application relates to the technical field of water purification, and in particular to a water purification device for a superimposed variable frequency water supply system. Background Technology

[0002] Water purification is a crucial process in variable frequency drive (VFD) water supply systems. Its purpose is to remove impurities, pollutants, and microorganisms from the water to meet different usage needs and ensure the normal operation of human health and industrial production.

[0003] A search revealed Chinese Patent Publication No. CN 221420707 U, which discloses a water purification device for a variable frequency water supply system. The device includes a main body with an internal replacement mechanism for quickly replacing the filter element. This mechanism comprises a filter block and a purification block. This invention relates to the field of water purification technology. The water purification device of this variable frequency water supply system allows for the sliding replacement of the purification block via a connecting block inside the main body. The surface of the main body is connected to a pipe via threads, thus purifying the water. The purification block can be removed by sliding the shaft and groove, allowing for rapid resetting of the purification block's effectiveness. The filter block is slidably connected inside the purification block, and the water purification material inside can be quickly replaced via the replacement block. This fast and convenient replacement, achieved through sliding, results in higher replacement efficiency.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: When using the water purification device of the existing booster frequency conversion water supply equipment, it is inconvenient to replace the internal activated carbon plate after prolonged water purification, which affects the water purification effect. The filtration effect on organic matter, odor, discoloration, and some heavy metal ions in the water becomes worse. At the same time, using a single filtration device can only perform single-function filtration, and the practical filter screen can only intercept larger particles of impurities in the water, such as silt and rust.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a water purification device for a superimposed frequency conversion water supply system. For example... Figures 1-4As shown, the device includes a base frame 1. Power grooves are fixedly installed at both ends of the base frame 1. A crossbar is fixedly installed on the inner wall of the power groove near the top. A snap-fit ​​plate 2 is slidably fitted onto the surface of the crossbar. A limit bolt 23 is rotatably installed on the outer side of the snap-fit ​​plate 2. The end of the limit bolt 23 away from the snap-fit ​​plate 2 is rotatably inserted into the outer side of the base frame 1. The snap-fit ​​plate 2 slides at the bottom of the base frame 1, facilitating the snap-fit ​​fixing in different positions and improving the practicality of the equipment. A purification box 3 is fixedly installed at the top of the base frame 1. Two filter screens 7 are fixedly installed on the left end of the top of the inner wall of the purification box 3. The two filter screens 7 serve as preliminary filters, intercepting larger particles of impurities in the water, such as silt and rust. The bottom and middle partition 4 of the filter screens 7... The upper surface slides in contact. A water inlet pipe 6 is fixedly installed on the top left side of the purification box 3. The water inlet pipe 6 is located at one end of the filter plate 7, so that the filter plate 7 is located at the water inlet. A water outlet pipe 10 is fixedly installed at the bottom right end of the purification box 3. A valve is fixedly installed in the middle of the water outlet pipe 10. A motor 20 is fixedly installed at the bottom of the inner wall of the purification box 3. A first pulley 5 is fixedly installed at the outer end of the output shaft of one end of the motor 20. A second pulley 12 is installed in the middle of the outer circumference of the first pulley 5 through the belt strip 21. The middle of the second pulley 12 is fixedly sleeved on the outer circumference of the middle of the rotating shaft 13. A support plate 11 is rotatably sleeved on the outer circumference of one end of the rotating shaft 13. The bottom of the support plate 11 is fixedly installed at the bottom of the inner wall of the purification box 3.

[0025] Please see Figure 2 Two eccentric wheels 14 are fixedly sleeved on the outer circumferential surface of the rotating shaft 13 near one end. The two eccentric wheels 14 move under the action of the rotating shaft 13, making the vibration of the upper middle partition 4 more stable. The connection between the two eccentric wheels 14 and the rotating shaft 13 is located at one-third away from the center. The connection between the eccentric wheels 14 and the rotating shaft 13 at one-third away from the center enables the middle partition 4 to vibrate under the thrust of the rotating eccentric wheels 14. The two eccentric wheels 14 are located at both ends of the rotating shaft 13.

[0026] Please see Figure 2 A central partition 4 is slidably provided on the outer side of the eccentric wheel 14. The central partition 4 is made of deformable rubber plate and is inclined at 30 degrees. The left end of the central partition 4 is higher than the right end. The central partition 4, which is made of special material, is designed to ensure that it can vibrate and prevent water stains from remaining on the surface of the central partition 4 after long-term use, thus ensuring that the surface of the central partition 4 is kept clean.

[0027] Please see Figure 2 and Figure 3The two ends of the middle partition 4 are fixedly installed on the inner wall of the purification box 3 near the bottom. An activated carbon box 9 is fixedly installed on one end of the upper surface of the middle partition 4. A push plate 24 is slidably installed on the bottom of the inner wall of the activated carbon box 9. An arc-shaped elastic plate 22 is fixedly installed on the outer side of the push plate 24. The two ends of the arc-shaped elastic plate 22 are fixedly installed on the bottom of the inner wall of the activated carbon box 9. There are two push plates 24, which are symmetrically arranged on the bottom of the inner wall of the activated carbon box 9. When the activated carbon plate 17 is installed downwards, the two push plates 24 are pushed outwards. Under the action of the arc-shaped elastic plate 22, the two push plates 24 are pushed towards the activated carbon plate 17, ensuring that the activated carbon plate 17 is stably placed after installation.

[0028] Please see Figure 3 The top of the activated carbon box 9 is connected to the top of the purification box 3. A filter screen plate 7 is slidably installed on the bottom of the inner wall of the activated carbon box 9. A top plate 18 is snapped onto the top of the filter screen plate 7. An activated carbon plate 17 is snapped onto the bottom of the top plate 18. The activated carbon plate 17 is designed to remove organic matter, odors, discoloration, and some heavy metal ions from the water by utilizing the adsorption properties of activated carbon. The bottom of the activated carbon plate 17 is in sliding contact with the inner side of the push plate 24. A bottom plate is snapped onto the bottom of the activated carbon plate 17. Arc-shaped slide rails are fixedly installed at both ends of the upper surface of the bottom plate. A vertical slide groove 16 is slidably fitted onto the outer side of the arc-shaped slide rails. The activated carbon plate 17 drives the bottom plate to slide inside the vertical slide groove 16. At the same time, the vertical slide groove 16 limits the two ends of the activated carbon plate 17 to prevent the two ends of the activated carbon plate 17 from shifting when impacted by water flow. The bottom of the vertical slide groove 16 is fixedly installed at the bottom of the inner wall of the activated carbon box 9.

[0029] Please see Figure 2 and Figure 3 The top plate 18 has two fixed clamping plates 8 at both ends. An elliptical plate 19 is fixedly installed on the top of the inner side of the clamping plate 8. The elliptical plate 19 is shaped like an "8". The bottom diameter of the elliptical plate 19 is larger than the inner width of the groove at the top of the support rod 15. There are four elliptical plates 19. Two elliptical plates 19 are symmetrically arranged at both ends of the top plate 18. The "8" shaped elliptical plates 19 are inserted into the top of the support rod 15 so that the elliptical plates 19 are in a stable state after insertion. The elliptical plates 19 can be pulled upward by external force to achieve the effect of disassembling and assembling the top plate 18. The bottom of the elliptical plate 19 is clamped to the support rod 15. The bottom of the support rod 15 is fixed to the bottom of the inner wall of the activated carbon box 9.

[0030] The implementation principle of the water purification device of the superimposed frequency conversion water supply equipment in this application embodiment is as follows: During use, the inlet pipe 6 is connected to an external water pipe, and the liquid enters the purification tank 3. It undergoes preliminary filtration through the filter screen 7, which intercepts larger particles of impurities in the water, such as silt and rust. The filter screen 7 is positioned on the right side of the inlet pipe 6, serving as the initial filtration mechanism and protecting subsequent purification equipment and water supply system components from damage by large particles. After preliminary filtration through the filter screen 7, the water flows through the activated carbon tank 9. Passing through the internal activated carbon plate 17, the activated carbon utilizes its adsorption properties to remove organic matter and odors from the water. The activated carbon plate 17, located behind the filter screen plate 7, effectively improves the taste and odor of water and enhances the sensory indicators of water quality, removing discoloration and some heavy metal ions. When it is necessary to replace the internal activated carbon plate 17, the activated carbon plate 17 can be pulled out by moving the top plate 18 away from the purification box 3. After long-term use, the starting motor 20, through the cooperation of the pulley, drives the rotating shaft 13 to drive the eccentric wheel 14 to rotate, thereby vibrating the middle partition 4, which vibrates the impurities remaining in the water on the surface, preventing them from adhering to the partition surface, facilitating cleaning, and ensuring unobstructed internal flow.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
