Description

Technical Field

[0001] This application relates to the technical field of swimming pool water filtration, and in particular to a high-performance regenerable media filter. Background Technology

[0002] In the current use of swimming pools, a circulating purification water supply system is generally adopted. The circulating purification water supply system uses a regenerating media filter, among which perlite is the most common regenerating media. It has high filtration accuracy and can intercept suspended matter as small as 1 micron, and the turbidity can be controlled below 0.1 NTU.

[0003] However, existing regenerable media filters need to be re-coated after a period of use. Coating requires automated systems and circulation pumps, resulting in high usage and maintenance costs.

[0004] Therefore, there is an urgent need to develop a filter that has good performance and is easy to use and maintain. Utility Model Content

[0005] The purpose of this application is to provide a high-performance regenerable media filter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a high-performance regenerable media filter using the following technical solution:

[0007] A high-performance regenerative media filter includes a cylinder, a top cover, and a filter element. The filter element is disposed in the cylinder, and the top cover is detachably mounted on the cylinder. The bottom end of the filter element is sealed against the bottom of the cylinder, and the top end of the filter element is sealed against the inner wall of the top cover. A drain pipe is provided in the middle of the cylinder corresponding to the filter element, and a water inlet pipe is provided on the side of the cylinder.

[0008] The filter element includes an annular hollow frame, with sealing plates fixed at both the top and bottom. Both the inner and outer annular surfaces of the annular hollow frame are covered with a leak-proof layer. The annular hollow frame is filled with perlite filter aid. An annular paddle is also provided inside the annular hollow frame. Vertical rods are symmetrically fixed on both sides of the top of the annular paddle, penetrating the top sealing plate. A sealing element connects the vertical rod to the sealing plate. An electric push rod is fixed to the top cover, driving the vertical rod to move up and down.

[0009] Preferably, in order to reduce water resistance, the cross-section of the annular lever is rhomboid.

[0010] Preferably, in order to make the overall structure more aesthetically pleasing and compact, the surface of the top cover is provided with a groove, the electric push rod is installed in the groove, the top end of the piston rod of the electric push rod is fixed with a pressure plate by a stud, the two ends of the pressure plate are sleeved on the top end of the vertical rod and fixed to the vertical rod by nuts.

[0011] The leak-proof layer is a PET film with evenly spaced micropores on its surface, and the particle size of the perlite filter aid is larger than the micropore size of the membrane fibers.

[0012] Preferably, since the perlite filter aid particles have low buoyancy and will float, in order to prevent sewage from flowing away from the bottom of the perlite filter aid particle layer, an annular baffle is provided on the side wall near the bottom of the inner ring surface of the annular hollow skeleton, and the perlite filter aid filling amount in the annular hollow skeleton is higher than that of the annular baffle.

[0013] A drain pipe is also provided on the bottom side of the cylinder.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. This high-performance regenerable media filter has a simple structure and is easy to use. It is equipped with a filter element filled with perlite filter aid, which forms a relatively thick filter layer. When sewage passes through it, the perlite filter aid can intercept suspended matter as small as 1 micron, achieving a good filtration effect in one pass. This allows the turbidity of the pool water to be quickly controlled below 0.1 NTU, resulting in good filtration effect and strong filtration performance.

[0016] 2. The filter element is equipped with an annular disc. Using an electric push rod, pressure plate and vertical rod, the annular disc moves up and down with a mechanical structure. The annular disc can agitate the perlite filter aid particles, causing changes in the perlite filter aid particles near the outer ring surface of the annular hollow skeleton, preventing the perlite filter aid particles in this area from becoming saturated with adsorption, thereby improving the filtration effect.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] This application discloses a high-performance regenerative media filter, referring to... Figure 1-3 The system includes a cylinder body 1, a top cover 2, and a filter element 3. The filter element 3 is installed inside the cylinder body 1. The top cover 2 is detachably installed on the cylinder body 1. The bottom end of the filter element 3 is sealed against the bottom of the cylinder body 1, and the top end of the filter element 3 is sealed against the inner wall of the top cover 2. A drain pipe 11 is provided in the middle of the cylinder body 1 corresponding to the filter element 3, and a water inlet pipe 12 is provided on the side of the cylinder body 1.

[0023] The filter element 3 includes an annular hollow skeleton 31, with sealing plates 32 fixed at both the top and bottom. Both the inner and outer annular surfaces of the annular hollow skeleton 31 are covered with a leak-proof layer. The annular hollow skeleton 31 is filled with perlite filter aid 33. The perlite filter aid 33 particles are highly irregularly curled and sheet-like, forming a filter cake with a porosity of 80%-90%. Each particle has numerous interconnected capillaries, allowing for rapid filtration and the capture of ultrafine particles smaller than 1 micrometer. A key advantage of perlite filter media is its ability to retain solids while maintaining a high liquid flow rate. It exhibits good chemical stability and is free of potential contaminants, with a heavy metal ion content typically below 0.005%, making it suitable for food-grade filtration.

[0024] The annular hollow frame is also equipped with an annular paddle 34. The cross-section of the annular paddle 34 is rhomboid. Vertical rods 35 are symmetrically fixed on both sides of the top of the annular paddle 34. The vertical rods 35 pass through the top sealing plate 32 and are connected to the sealing plate 32 with a sealing element. An electric push rod 4 is fixed on the top cover 2. The electric push rod 4 is used to drive the vertical rod 35 to move up and down.

[0025] The leak-proof layer is a PET film with evenly spaced micropores on its surface. The particle size of the perlite filter aid 33 is larger than the micropore size of the membrane fibers. The PET film has high tensile strength, tear strength and puncture resistance, and is tough and durable, able to withstand large external forces without being easily damaged.

[0026] An annular baffle 5 is provided on the side wall of the annular hollow skeleton 31 near the bottom of the inner ring surface, and the amount of perlite filter aid 33 inside the annular hollow skeleton is higher than that of the annular baffle 5.

[0027] Reference Figure 1 To make the structure more compact, the top cover 2 has a groove 21 on its surface. The electric push rod 4 is installed in the groove 21. The piston rod of the electric push rod 4 is fixed with a pressure plate 6 by a stud. The two ends of the pressure plate 6 are sleeved on the top of the vertical rod 35 and fixed to the vertical rod 35 by nuts. In order to realize automated control, the electric push rod 4 can be connected to an external time delay relay.

[0028] To facilitate cleaning of the filter, a drain pipe 13 is also provided on the bottom side of the cylinder 1, and a valve is installed in the drain pipe 13.

[0029] The implementation principle of a high-performance regenerable media filter according to an embodiment of this application is as follows:

[0030] Wastewater enters the tank 1 through the inlet pipe 12, passes through the filter element 3 to reach the internal space of the filter element, and is then discharged and circulated through the drain pipe 11. When the wastewater passes through the perlite filter aid 33, impurities can be captured by the perlite filter aid 33 particles, and suspended matter as small as 1 micron is intercepted, so that the turbidity of the pool water can be controlled below 0.1 NTU, and the filtration effect is good.

[0031] With the ring-shaped paddle 34 in place, the electric push rod 4 operates at regular intervals. The electric push rod 4 drives the ring-shaped paddle 34 to move up and down via the pressure plate 6 and the vertical rod 35. The ring-shaped paddle 34 can agitate the perlite filter aid 33 particles, causing changes in the perlite filter aid 33 particles near the outer ring surface of the annular hollow skeleton 31. This prevents the perlite filter aid 33 particles in this area from becoming saturated with adsorption, thereby improving the filtration effect.

[0032] 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.
