Description

Technical Field

[0001] This application relates to the field of preventing scale formation, and in particular to a water treatment method and apparatus that combines scale inhibition and antibacterial functions. Background Technology

[0002] In the field of water treatment, scale formation and the growth of bacteria and algae are two core pain points affecting the lifespan of pipe networks and water quality safety. In recent years, filter cartridges made of multi-element alloy materials (such as alloys containing copper, zinc, nickel, or with additional elements such as Ag, Al, Sn, Si, Bi, Sb, and Re) have been widely used due to their excellent treatment effect.

[0003] The core mechanism of multi-element alloy materials in water treatment lies in a purely physical electrochemical reaction: utilizing the inherent potential difference between different metal elements, countless "micro-battery systems" spontaneously form in the water. When the water to be treated flows through these alloy materials, the electrons released by the micro-batteries enhance the polarity of the water dipoles, altering the binding field of scale-forming ions, thereby achieving scale prevention and inhibition. Simultaneously, this micro-electric field effectively breaks down the lattice bonds of existing scale, making its structure loose and causing it to detach. Furthermore, because the release of electrons hinders the binding of positive and negative ions in the saponification reaction, it can directly block the cell division of microorganisms such as bacteria and algae. This purely physical water treatment method has significant advantages such as not adding any chemical agents, no secondary pollution, and continuous activation of water quality.

[0004] However, despite the significant advantages of multi-element alloy materials in terms of their mechanism, the following technical bottlenecks remain insurmountable in existing water treatment applications: Filter cartridges made of multi-element alloys are often porous or honeycomb-shaped to increase the surface area in contact with water. However, their effectiveness depends on direct contact between their surface and the water. During long-term physicochemical reactions, suspended solids, detached scale residue, and dead bacteria and algae in the water are adsorbed and adhere to the surface of the alloy filter cartridge, forming a dense layer of dirt or passivation. This passivation layer acts as an insulator, directly blocking electron exchange between the micro-battery system and the water. Furthermore, the deep-seated dirt is difficult to clean, causing the filter cartridge's scale-inhibiting and antibacterial functions to rapidly diminish. Summary of the Invention

[0005] In order to improve the problem that a dense layer of dirt or passivation forms on the surface of the alloy filter element and is difficult to clean, which leads to a rapid decline in the scale inhibition and antibacterial functions of the entire filter element, this application provides a water treatment device that has both scale inhibition and antibacterial functions.

[0006] The water treatment device provided in this application, which combines scale inhibition and antibacterial functions, adopts the following technical solution: A water treatment device with both scale inhibition and antibacterial functions includes: a water purification tank having an inlet, an outlet, an installation chamber, a purified water chamber located below the installation chamber, and an installation port connecting the installation chamber and the purified water chamber; a scale inhibition and antibacterial filter element assembly disposed at the installation port and abutting against the inner wall of the installation port; the scale inhibition and antibacterial filter element assembly includes: a filter housing having a closed side and two opposing filter ends; the filter ends are disposed at the installation port, and the filter housing is located below the installation port; a first connecting pipe connecting from inside or outside the water purification tank to one side of the filter housing; a second connecting pipe connecting from inside or outside the water purification tank to the other side of the filter housing; a conveying mechanism disposed in the inlet pipe and / or the outlet pipe; and the filter housing being filled with multi-element alloy metal particles.

[0007] By adopting the above technical solution, the water to be treated enters through the inlet and flows through the filter housing and the alloy metal particles inside the filter housing. The alloy metal particles are used to treat the water by inhibiting scale and bacteria. In addition, because the alloy metal particles are in contact with the water to be treated for a long time, some stains can easily adhere to the surface of the alloy metal particles, affecting the contact area between the alloy metal particles and the water to be treated. By filling the filter housing with alloy metal particles, the alloy metal particles inside the filter housing can play the same water treatment role as traditional filter cartridges. Furthermore, the alloy metal particles are replaceable, and can be replaced when excessive stains adhere to their surface and affect the treatment effect.

[0008] This application utilizes a first connecting pipe, a second connecting pipe, and a conveying mechanism to add and discharge alloy metal particles inside the filter housing. This allows for the timely removal of dirt adhering to the surface of the alloy metal particles, replacing them with new alloy metal particles. This facilitates maintaining high-efficiency scale inhibition and antibacterial treatment over a long period.

[0009] Meanwhile, the conveying mechanism feeds alloy metal particles into and out of the filter housing. It can dynamically rotate to feed more or less alloy metal particles and to discharge more or less alloy metal particles according to the treatment requirements. It can also dynamically adjust the squeezing pressure of the alloy metal particles in the filter housing, so that the gaps between the alloy metal particles are squeezed tighter or looser, and can be dynamically adjusted according to the water treatment requirements.

[0010] Furthermore, the conveying mechanism includes: a shaft component, a spiral plate disposed on the shaft component, and a drive component connected to the shaft component; the shaft component extends through the first connecting pipe, the filter housing, and the second connecting pipe.

[0011] By adopting the above technical solution, the driving component drives the shaft component to rotate, and the shaft component passes through the first connecting pipe, the filter housing, and the second connecting pipe. Then, the spiral plate can transport the alloy metal particles as the shaft component rotates, so that the alloy metal particles are input into the filter housing in the first connecting pipe and input into the second connecting pipe in the filter housing and output outward, thereby realizing the replacement of alloy metal particles.

[0012] Furthermore, a rotating brush body is also provided on the shaft component; the spiral plate is provided in two sections, and the rotating brush body is located between the two sections of the spiral plate; both sections of the spiral plate are provided inside the second connecting pipe.

[0013] By adopting the above technical solution, the second connecting pipe is equipped with two spiral plates and a rotating brush body disposed between the two spiral plates. Thus, both spiral plates and the rotating brush body can rotate. The spiral plates are responsible for driving the conveying of alloy metal particles. During the conveying process, the alloy metal particles pass through the rotating brush body. The rotating brush body uses its own rotation and relative movement with the alloy metal particles to brush the surface of the alloy metal particles. When the alloy metal particles are discharged from the second connecting pipe, the dirt adhering to the surface of the alloy metal particles is cleaned, making it easy for the discharged alloy metal particles to be quickly put into use or sent back to the filter housing from the second connecting pipe for use.

[0014] Furthermore, the shaft component is provided with multiple rotating connecting parts, and the spiral plate and the rotating brush body are disposed on the rotating connecting parts; the driving component has multiple driving ends, and the driving ends are connected to the rotating connecting parts.

[0015] By adopting the above technical solution, multiple drive ends of the drive component are connected to multiple rotating connecting parts, allowing all or some of the rotating connecting parts to maintain independent drive control. This enables individual control of the rotation and stopping of the spiral plates and the rotating brush body. Consequently, the spiral plates can transport alloy metal particles to the rotating brush body, and then either neither spiral plate rotates, or one spiral plate rotates while the other does not, or the rotation direction can be controlled so that the conveying direction of both spiral plates is towards the rotating brush body, allowing the alloy metal particles to remain at the rotating brush body for brushing. This improves the cleaning effect of alloy metal particles.

[0016] Furthermore, an annular flexible or elastic mechanism is provided on the outside of the rotating brush body, and the flexible or elastic mechanism is fixed to the inner wall of the second connecting tube; a fixed brush body is provided on the flexible or elastic mechanism, and there is a gap between the fixed brush body and the rotating brush body to accommodate alloy metal particles.

[0017] By adopting the above technical solution, the fixed brush body set on the flexible or elastic mechanism has a deformable function due to the flexibility or elasticity of the flexible or elastic mechanism itself. It can accommodate the alloy metal particles between the rotating brush body and the fixed brush body in real time according to the amount of alloy metal particles. Then, the rotating brush body rotates and the fixed brush body provides a variable elastic support force as the alloy metal particles move or brush, so that the alloy metal particles are better brushed between the rotating brush body and the fixed brush body.

[0018] Furthermore, the flexible or elastic mechanism includes an annular bladder and an injection tube, the injection tube passing through the second connecting tube and communicating with the annular bladder, and the injection tube being externally connected to a water injection or air injection mechanism; the outer ring of the annular bladder is connected to the inner wall of the second connecting tube, and the fixed brush body is disposed in the inner ring of the annular bladder.

[0019] By adopting the above technical solution, utilizing the annular bag design and the injection pipe and water or air injection mechanism, the annular bag can be expanded to a state where it is not easily deformed, or partially contracted to a state where it is easily deformed. This allows for the annular bag to first be adjusted to a state where it is easily deformable, then more alloy metal particles are filled between the rotating brush body and the fixed brush body, and finally the annular bag is adjusted to an expanded state where it is not easily deformed. At this point, the alloy metal particles are compressed, and the rotating and fixed brush bodies exert a stronger scrubbing force on the alloy metal particles.

[0020] Furthermore, the rotating brush body includes a long brush bar and a short brush bar, both of which are distributed along a spiral trajectory to form a spiral receiving groove.

[0021] By adopting the above technical solution, the setting of the long brush rod and the short brush rod of the rotating brush body can ensure that multiple surfaces of the alloy metal particles are in contact with the long brush rod, the short brush rod and the fixed brush body when the alloy metal particles are in the spiral receiving groove, which greatly improves the efficiency of brushing the alloy metal particles.

[0022] Further, the second connecting pipe includes: a first pipe section connected to the filter housing, a detachable pipe section connected to the first pipe section, and a second pipe section connected to the detachable pipe section; the diameter of the detachable pipe section is larger than the diameters of the first pipe section and the second pipe section; a first connecting part is provided at the top of the detachable pipe section, and a second connecting part is provided at the bottom of the detachable pipe section; a first quick-release part is provided at the bottom of the first pipe section to seal with the first connecting part, and a second quick-release part is provided at the top of the second pipe section to seal with the second connecting part.

[0023] By adopting the above technical solution, the detachable pipe section can be disassembled relative to the first and second pipe sections, and then moved downward or upward, so that the rotating brush body is exposed outward, thereby facilitating the cleaning of the rotating brush body and maintaining the cleaning effect on alloy metal particles.

[0024] Furthermore, both the long brush rod and the short brush rod extend along a direction perpendicular to the axis of the second connecting tube; both the long brush rod and the short brush rod are provided with auxiliary brush rods, which are perpendicular to the long brush rod and the short brush rod.

[0025] By adopting the above technical solution, when the fixed brush body, the rotating brush body, and the alloy metal particles are tightly attached, the brush handles of the fixed brush body and the rotating brush body will not be in contact with the alloy metal particles at their ends, but rather at their sides. Therefore, auxiliary brush handles are set on both the long and short brush handles. The ends of the auxiliary brush handles can contact the alloy metal particles, allowing the fixed brush body and the rotating brush body to clean the alloy metal particles more efficiently.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The water to be treated enters through the inlet and flows through the filter housing and the alloy metal particles inside the housing. These alloy metal particles inhibit scale growth and bacteria growth in the water. However, because the alloy metal particles are in prolonged contact with the water, dirt can easily adhere to their surface, reducing the contact area. By filling the filter housing with alloy metal particles, the particles can achieve the same water treatment effect as traditional filter cartridges. Furthermore, these alloy metal particles are replaceable; they can be replaced when excessive dirt buildup affects the treatment performance.

[0027] Through the design of the first connecting pipe, the second connecting pipe, and the conveying mechanism, when the multi-element alloy particles inside the filter housing become stained and the micro-electric field release weakens due to prolonged operation, the conveying mechanism can be activated without stopping the machine or disassembling the water purification tank. This mechanism expels the old, worn-out particles through the discharge pipe and simultaneously replenishes the filter housing with new alloy particles through the injection pipe. This ensures that the filter housing always maintains a clean, highly active metal surface in contact with the water flow, thereby continuously maintaining the electron release of the micro-battery system and effectively and stably performing its core functions of breaking down scale lattice bonds and inhibiting bacterial division.

[0030] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application are described clearly and completely below in conjunction with embodiments of this application. It is understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0032] In the description of this application, it should be noted that the terms "first," "second," etc., are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. The terms "connection," "setup," and "installation" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] This application provides a water treatment device that combines scale inhibition and antibacterial functions. It is mainly used for efficient physical treatment of flowing water to prevent scale formation and inhibit bacterial growth. The water treatment device mainly includes a water purification tank 1, a scale inhibition and antibacterial filter element assembly, a connecting pipeline system, and a conveying mechanism 5.

[0034] In this embodiment, the water purification tank 1 serves as the main supporting structure of the whole, and is provided with an inlet 11 and an outlet 12 for connecting to an external water circuit to be treated. The interior of the water purification tank 1 has an interconnected installation chamber 13 and a water purification chamber 14 located below the installation chamber 13. An installation port 15 is provided between the installation chamber 13 and the water purification chamber 14 to connect the two.

[0035] The scale-inhibiting and antibacterial filter element assembly is located at the mounting port 15, and its outer wall is tightly abutted against the inner wall of the mounting port 15 to ensure that the water to be treated must pass through the filter element assembly and that no bypass leakage occurs from the gaps. Specifically, the scale-inhibiting and antibacterial filter element assembly includes a filter housing 2, which has a closed side 21 and two opposing filter ends 22. The filter ends 22 are located at the mounting port 15, and the filter housing 2 is located at the lower part of the mounting port 15, thereby guiding the water flow using the combined effect of gravity and water pressure.

[0036] The filter housing 2 is filled with multi-element alloy metal particles. The water to be treated enters the installation chamber 13 through the inlet 11, then flows through the filter end 22 of the filter housing 2 and passes through the interior of the filter housing 2. During this process, the water comes into full contact with the alloy metal particles, utilizing the microcurrent and metal ion properties released by the alloy metal particles to achieve efficient scale inhibition and antibacterial treatment of the water. The treated purified water then flows into the purified water chamber 14 and is finally discharged from the outlet 12.

[0037] Because alloy metal particles are in contact with the water to be treated for a long time, their surface is very prone to adhering to stains or suspended matter in the water or undergoing oxidation and passivation, which reduces the effective contact area between them and the water, thus affecting the scale inhibition and antibacterial effect.

[0038] Specifically, the scale-inhibiting and antibacterial filter cartridge assembly also includes a first connecting pipe 3 and a second connecting pipe 4. The first connecting pipe 3 is connected from inside the water purification tank 1 to one side of the filter housing 2; the second connecting pipe 4 is connected from inside the water purification tank 1 to the other side of the filter housing 2. In this structure, the first connecting pipe 3 constitutes the injection for new particles, and the second connecting pipe 4 constitutes the discharge for old particles.

[0039] A conveying mechanism 5 is provided within the first connecting pipe 3 and / or the second connecting pipe 4. In a preferred embodiment, the conveying mechanism 5 includes: a shaft component 55, a spiral plate 52 disposed on the shaft component 55, and a drive component 53 connected to the shaft component 55. The shaft component 55 passes through the first connecting pipe 3, the filter housing 2, and the second connecting pipe 4 sequentially along the pipeline route.

[0040] In some designs, the first connecting pipe 3 can be connected to a new metal particle storage box, and the second connecting pipe 4 can be connected to an old metal particle storage box.

[0041] The working logic is as follows: When the particles need to be replaced or adjusted, the drive unit 53 is activated. The drive unit 53 drives the shaft component 55 to rotate, and the spiral plate 52 fixed on the shaft component 55 rotates accordingly, pushing the new alloy metal particles in the first connecting pipe 3 into the filter housing 2, while simultaneously pushing the old alloy metal particles with dirt adhering to the inner surface of the filter housing 2 towards the second connecting pipe 4. This design achieves "activation" and "online replacement" of the filter media without stopping the machine to disassemble the entire filter element.

[0042] Furthermore, by precisely controlling the rotation speed, forward and reverse rotation, and conveying volume of the drive component 53, the conveying mechanism 5 can dynamically increase or decrease the amount of particles fed in according to the real-time requirements of water treatment, thereby dynamically adjusting the compressive force between the alloy metal particles inside the filter housing 2. When it is necessary to improve the filtration accuracy, the compression is increased to make the gaps between the particles tighter; when it is necessary to increase the water flow rate, the reverse operation is used to loosen the gaps. For example, both the first connecting pipe 3 and the second connecting pipe 4 are equipped with conveying mechanisms 5. The first connecting pipe 3 injects alloy metal particles into the filter housing 2, while the second connecting pipe 4 does not discharge alloy metal particles outward, thereby increasing the compression to make the gaps between the particles tighter.

[0043] In some other embodiments, a rotating brush body 54 is also provided on the shaft component 55. The spiral plate 52 of the conveying mechanism 5 located in the second connecting pipe 4 is divided into two sections, and the rotating brush body 54 is located between the two spiral plate sections 52. Both spiral plate sections 52 and the rotating brush body 54 are located inside the second connecting pipe 4.

[0044] The shaft component 55 is provided with multiple rotating connecting parts, and the two spiral plates 52 and the rotating brush body 54 are respectively disposed on different rotating connecting parts. Correspondingly, the drive component 53 has multiple drive ends, and different drive ends are connected to the corresponding rotating connecting parts.

[0045] Specifically, the drive component 53 can be a combination of a motor and belt drive, gear drive, or sprocket drive. The drive end is a structure in which the motor output shaft outputs rotational power outward through belt drive, gear drive, or sprocket drive. The shaft component 55 includes a first transmission tube 551, a second transmission tube 552, and a transmission shaft 553 that are sequentially inserted or sleeved together. The rotatable connection part is the outer wall of the first transmission tube 551, the second transmission tube 552, and the transmission shaft 553. One spiral plate 52 is disposed on the first transmission tube 551, and the other spiral plate 52 is disposed on the transmission shaft 553. The rotating brush body 54 is disposed on the second transmission tube 552. Therefore, the rotatable connection part is the part where the first transmission tube 551, the second transmission tube 552, and the transmission shaft 553 are connected to the spiral plate 52 and the rotating brush body 54. Three motors can be set. One motor is connected to the first transmission tube 551 via belt pulley, gear drive, or sprocket drive. The second motor is connected to the second transmission tube 552 in the same way. The third motor is connected to the transmission shaft 553 in the same way, so as to realize the individual control of the rotation of the two spiral plates 52 and the rotating brush body 54.

[0046] In other designs, only one first transmission pipe 551 and one transmission shaft 553 may be provided. The upper spiral plate 52 is connected to the first transmission pipe 551, and the lower spiral plate 52 and the rotating brush body 54 are connected to the transmission shaft 553.

[0047] In other designs, a first transmission pipe 551, a second transmission pipe 552, a third transmission pipe, and a transmission shaft 553 can be sequentially connected. The spiral plate 52 in the first connecting pipe 3, the two spiral plates 52 in the second connecting pipe 4, and the rotating brush body 54 are sequentially mounted on the first transmission pipe 551, the second transmission pipe 552, the third transmission pipe, and the transmission shaft 553.

[0048] Through the aforementioned multi-drive design, independent drive control of the two spiral plates 52 and the rotating brush body 54 can be achieved, meaning each can rotate, stop, and change direction independently. During particle washing, the first spiral plate 52 transports the alloy metal particles from the filter housing 2 to the rotating brush body 54. Subsequently, both spiral plates 52 are controlled to stop rotating, or the first spiral plate 52 is controlled to rotate clockwise while the second spiral plate 52 rotates counterclockwise, ensuring the conveying direction is towards the central rotating brush body 54. This "locks" the alloy metal particles to be cleaned and keeps them in the position of the rotating brush body 54. At this time, the rotating brush body 54 continues to rotate, using the relative friction between itself and the particles to powerfully scrub the dirt adhering to the surface of the alloy metal particles. After washing, the second spiral plate 52 rotates clockwise, discharging the cleaned particles. In some cases, the regenerated particles can be recycled back into the filter housing 2 by reversing the rotation. For example, if the first connecting pipe 3 and the second connecting pipe 4 are set at an angle or horizontally relative to the filter housing 2, the cleaned alloy metal particles can be quickly and easily sent back into the filter housing 2 by the reverse rotation of the spiral plate 52.

[0049] In other embodiments, An annular flexible or elastic mechanism is coaxially arranged outside the rotating brush body 54 inside the second connecting tube 4. The outer ring of the flexible or elastic mechanism is fixedly connected to the inner wall of the second connecting tube 4, and a fixed brush body 51 is provided on its inner ring surface. A gap is formed between the fixed brush body 51 and the internal rotating brush body 54 to accommodate alloy metal particles.

[0050] In a more specific embodiment, the flexible or elastic mechanism is specifically an annular pouch 6. Correspondingly, an injection tube 7 is also provided, which passes through the wall of the second connecting tube 4 and connects to the internal chamber of the annular pouch 6. The injection tube 7 is externally connected to a water or air injection mechanism 71. A fixed brush body 51 is arranged in the inner ring of the annular pouch 6. The water or air injection mechanism 71 is a water pump or an air pump.

[0051] One type of motion process is as follows: During the feeding stage: the water injection or air injection mechanism 71 pumps air / water, causing the annular bag 6 to shrink to a soft state that is prone to deformation. At this time, the gap between the fixed brush body 51 and the rotating brush body 54 increases, allowing more alloy metal particles to fill and be accommodated in the gap smoothly.

[0052] During the washing stage: The water injection or air injection mechanism 71 injects water or inflates the annular bag 6, causing the annular bag 6 to expand to a firm state that is not easily deformed. The expanded bag is squeezed towards the center, causing the fixed brush body 51 to press inward, applying a variable elastic support force and compressive force to the alloy metal particles in the gap.

[0053] During the cleaning phase: At this time, the rotating brush body 54 is activated. The particles are strongly rubbed under the dual action of the static friction of the external fixed brush body 51 and the dynamic friction of the internal rotating brush body 54, which greatly improves the cleaning power and stain removal efficiency.

[0054] Specifically, the rotating brush body 54 includes a long brush rod 541 and a short brush rod 542. The length direction of both the long brush rod 541 and the short brush rod 542 extends in a direction perpendicular to the axis of the second connecting tube 4, that is, radially, and both are distributed alternately on the outer cylindrical surface along a spiral trajectory, thereby naturally forming a spiral receiving groove 544 between the long brush rod 541 and the short brush rod 542.

[0055] Furthermore, on the main body of both the long brush rod 541 and the short brush rod 542, there are auxiliary brush rods 543 arranged in a divergent shape, and the auxiliary brush rods 543 are perpendicular to the main direction of the long brush rod 541 and the short brush rod 542.

[0056] When the alloy metal particles enter the spiral receiving groove 544, the long brush rod 541, short brush rod 542, auxiliary brush rod 543, and the surrounding fixed brush body 51 construct a three-dimensional, fully enclosed brushing space. In particular, the auxiliary brush rod 543 solves the problem that when particles are tightly adhered to each other, the main brush rod can often only contact the particles from the side. The end of the auxiliary brush rod 543 can directly pierce the surface of the particles or penetrate the surface of particles with tiny pits, forming end-point contact with the particles, thus ensuring deep cleaning of multiple surfaces or irregular surfaces of the alloy metal particles.

[0057] In other embodiments, The second connecting pipe 4 is divided into three sections axially, including: a first pipe section 41 connected to the filter housing 2 at one end, a detachable pipe section 42 connected to the first pipe section 41, and a second pipe section 43 connected to the detachable pipe section 42. The area containing the rotating brush body 54 and the annular bag 6 is located within the detachable pipe section 42. To accommodate the expanding bag and facilitate particle flow, the diameter of the detachable pipe section 42 is set larger than the diameters of the first pipe section 41 and the second pipe section 43.

[0058] The top of the detachable pipe section 42, near the end of the first pipe section 41, is provided with a first connecting part 44, and the bottom is provided with a second connecting part 45. Correspondingly, the bottom of the first pipe section 41 is provided with a first quick-release part 46 that seals with the first connecting part 44, and the top of the second pipe section 43 is provided with a second quick-release part 47 that seals with the second connecting part 45. The first quick-release part 46 and the second quick-release part 47 can adopt known quick-release structures such as clamps, threaded sleeves, or flange snaps. The first connecting part 44 and the second connecting part 45 cooperate with the first quick-release part 46 and the second quick-release part 47. Preferably, the first quick-release part 46 and the second quick-release part 47 are threaded sleeves, which slide and rotate with the first pipe section 41 and the second pipe section 43. The first pipe section 41 and the second pipe section 43 are provided with protrusions that cooperate with the threaded sleeves. The first connecting part 44 and the second connecting part 45 are threaded structures located at the ends of the detachable pipe section 42 and threadedly connected to the threaded sleeves. The threaded sleeve is threadedly connected to the threaded structure, and a sealing ring 48 is provided inside the threaded sleeve to abut against the protrusion.

[0059] When maintenance is required, the operator only needs to unlatch the first quick-release part 46 and the second quick-release part 47 to detach the detachable tube section 42 relative to the first tube section 41 and the second tube section 43. After separation, the detachable tube section 42 can be slid axially downwards or upwards, so that the internal rotating brush body 54 and fixed brush body 51 are completely exposed to the outside. This greatly facilitates manual deep cleaning of stubborn impurities wrapped on the brush body, ensuring that the entire particle regeneration system is in optimal working condition for a long time.

[0060] 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.
