[0025] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, one embodiment of the present invention provides a filtration system for filtering magnetic impurities in a working fluid; the filtration system comprises: a water tank 11, a liquid inlet pipe 12, a liquid storage tank 13 and a magnetic component; the upper end of the water tank 11 is connected to the liquid storage tank 13, and the lower end is provided with a sewage outlet 112; the liquid inlet pipe 12 has a liquid inlet end and a liquid outlet end, the liquid outlet end of the liquid inlet pipe 12 is located in the water tank 11, and the working fluid discharged from the liquid outlet end of the liquid inlet pipe 12 has a tendency to flow into the liquid storage tank 13; the magnetic component is used to adsorb magnetic impurities in the working fluid when the working fluid discharged from the liquid outlet end of the liquid inlet pipe 12 flows into the liquid storage tank 13, and to enable the adsorbed magnetic impurities to move toward the sewage outlet 112.

[0027] The filtration system provided in this embodiment is used to separate magnetic impurities in the working fluid, thereby realizing the recovery of magnetic impurities. The above-mentioned working fluid can come from a wet shot blasting system. The water tank 11 is a cylindrical structure, and the water tank 11 has a box wall. The box wall facing the inside of the water tank 11 is the inner wall, and the box wall facing the outside of the water tank 11 is the outer wall. The liquid inlet pipe 12 is used to transport the working fluid into the water tank 11, and the liquid outlet end of the liquid inlet pipe 12 is located in the water tank 11; the working fluid enters the liquid inlet pipe 12 from the liquid inlet end of the liquid inlet pipe 12, and is then discharged into the water tank 11 from the liquid outlet end of the liquid inlet pipe 12. Initially, since there is no working fluid in the water tank 11, the working fluid cannot enter the liquid storage tank 13, and the working fluid must first fill the water tank 11; when the working fluid fills the water tank 11, the working fluid discharged from the liquid outlet end of the liquid inlet pipe 12 begins to flow into the liquid storage tank 13. As the working fluid flows into the liquid storage tank 13, the magnetic component can absorb magnetic impurities in the working fluid. Therefore, the filtrate that enters the liquid storage tank 13 is the filtrate after the magnetic impurities are removed. The liquid storage tank 13 is provided with an overflow port, and the filtrate in the liquid storage tank 13 is discharged in an overflow manner. Therefore, even if some fine magnetic impurities enter the liquid storage tank 13, they will sink to the bottom of the liquid storage tank 13 and will not be discharged from the liquid storage tank 13. The liquid storage tank 13 only needs to be cleaned regularly. After being absorbed by the magnetic component, the magnetic impurities will move toward the drain outlet 112 at the lower end of the water tank 11 under the action of the magnetic component, and finally be discharged from the water tank 11 through the drain outlet 112 and recycled. By utilizing the magnetic component to magnetically absorb the magnetic impurities in the working fluid and drive the magnetic impurities to move toward the drain outlet 112 of the water tank 11, the separation of magnetic impurities is achieved. Compared with the existing technology, there is no need to set up structures such as inclined plate sedimentation equipment, the utilization rate of the water tank 11 is improved, and the space occupied is small.

[0028] The filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, the upper end of the water tank 11 is open, and the upper edge of the wall of the water tank 11 is bent toward the outside of the water tank 11 to form a first flange 111; the lower end of the liquid storage tank 13 is provided with a through hole, and the inner edge of the through hole is bent toward the inside of the liquid storage tank 13 to form a second flange 131, and the first flange 111 and the second flange 131 are connected.

[0029] In this embodiment, the water tank 11 is a cylindrical structure with an open top, and the upper edge of the water tank 11 serves as a frame for the open end. The upper edge of the water tank 11 wall is bent outward to form a first flange 111. The first flange 111 is a portion of the water tank 11 wall, i.e., the water tank 11 wall is divided into a flange section and a cylindrical section. The first flange 111 can be welded to the water tank 11 wall or integrally formed. The liquid storage tank 13 is a disc-shaped structure with a through hole defined on its lower end. The inner edge of the through hole is bent inward to form a second flange 131. The outer contour of the first flange 111 is identical to the shape of the through hole, and the outer side of the first flange 111 is connected to the upper end of the second flange 131. During use, the working fluid enters the liquid storage tank 13 through the first flange 111. The second flange 131 separates the portion of the liquid storage tank 13 storing the filtrate from the water tank 11.

[0030] The filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, the magnetic component includes a controller and multiple electromagnets 14; all electromagnets 14 cover the tank wall of the water tank 11, and any two electromagnets 14 are spaced apart; all electromagnets 14 are electrically connected to the controller, and the controller is used to control the current value of the electromagnets 14.

[0031] The magnetic assembly includes a controller and multiple electromagnets 14. The electromagnets 14 are positioned on the outer wall of the water tank 11, and all of them completely cover the outer wall (including the area of ​​the first flange 111). Any two electromagnets 14 are spaced apart to save costs. All of the electromagnets 14 are electrically connected to the controller, which controls the current flowing through them. This ensures that, while attracting magnetic impurities, they can also transfer them from one electromagnet 14 to another by switching them on and off, thereby driving the impurities toward the sewage outlet 112. For example, in this embodiment, two electromagnets 14 are distributed on the outer wall of the water tank 11 at intervals. When both electromagnets 14 are energized, both electromagnets 14 can absorb magnetic impurities. When the current of the upper electromagnet 14 is reduced or the power is directly cut off, the magnetic impurities absorbed by the upper electromagnet 14 will be absorbed by the lower electromagnet 14. By continuously switching the power on and off of all the electromagnets 14, the magnetic impurities are continuously transferred from one electromagnet 14 to another electromagnet 14, and finally the magnetic impurities are transferred to the sewage outlet 112 at the lower end of the water tank 11 and discharged outward.

[0032] Optionally, in this embodiment, all electromagnets 14 are divided into multiple adsorption groups, each of which includes multiple electromagnets 14. The electromagnets 14 in the same adsorption group are spaced apart along the circumference of the water tank 11 on the outer wall of the water tank 11; the adsorption groups are spaced apart along the outer wall of the water tank 11 in a direction from the first flange 111 to the sewage outlet 112. By properly controlling the spacing between the electromagnets 14 and the current value of each electromagnet 14, the magnetic impurities are continuously transferred from one electromagnet 14 to another, and ultimately transferred to the sewage outlet 112 and discharged outward.

[0033] Moreover, in this embodiment, as the magnetic impurities continue to move downward, the magnetic impurities at the lower end will accumulate. Therefore, as a preference, the lower the electromagnet 14 is, the faster the frequency of switching on and off is, and the greater the current value when the electromagnet 14 is energized is. In this way, the magnetism of the electromagnet 14 is stronger, and more magnetic impurities can be adsorbed.

[0034] It can be understood that in this embodiment, the magnetic component can also include a conveyor chain and several permanent magnets; the conveyor chain is a closed structure formed by a plurality of chain links rotating and connected in sequence, and permanent magnets are provided on two adjacent chain links or two chain links arranged at intervals. Through the cooperation of the motor and several sprockets, the chain can move from the first flange 111 at the upper end of the water tank 11 to the sewage outlet 112 at the lower end of the water tank 11, thereby achieving the purpose of adsorbing magnetic impurities in the working fluid and transferring the magnetic impurities in the working fluid to the sewage outlet 112.

[0035] The filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, the portion of the liquid inlet pipe 12 located in the water tank 11 is vertically arranged, and the liquid outlet end of the liquid inlet pipe 12 faces the lower end of the water tank 11 .

[0036] In this embodiment, after the working fluid is discharged from the liquid outlet end of the liquid outlet pipe, it will move upward along the inner wall of the water tank 11, and then pass through the first flange 111 to enter the liquid storage tank 13. The working fluid flows very fast in the process of upward flow, and the working fluid will flush the inner wall of the water tank 11. Therefore, in order to avoid affecting the magnetic component to separate the magnetic impurities in the working fluid, the electromagnet 14 that plays an adsorption role is mainly the electromagnet 14 located at the first flange 111. In the process of the working fluid passing through the first flange 111 and entering the liquid storage tank 13, the magnetic impurities in the working fluid are adsorbed by the electromagnet 14 located at the first flange 111, and then transferred to the sewage outlet 112 by the electromagnets 14 at other positions. In order to improve the adsorption effect of the electromagnet 14 at the first flange 111, an embodiment of the present invention provides a filtration system, such as Figure 1As shown, the apparatus further includes a control assembly; the control assembly is at least partially located above the first flange 111. The control assembly is used to reduce the impact of the working fluid discharged from the liquid outlet end of the liquid inlet pipe 12 when it moves upward and enters the liquid storage tank 13, and to control the liquid level of the working fluid as it flows from the water tank 11 to the liquid storage tank 13. By arranging the control assembly at the first flange 111, the control assembly reduces the impact of the working fluid, thereby stabilizing the liquid level in the water tank 11. At the same time, it also controls the liquid level of the working fluid as it passes through the first flange 111, preventing the liquid level from being too high, thereby improving the adsorption effect of the electromagnet 14 at the first flange 111. Furthermore, since the upper end of the water tank 11 is connected to the liquid storage tank 13 on all sides, the control assembly can also forcibly distribute the liquid, thereby ensuring the adsorption effect of the magnetic assembly.

[0037] Optionally, the filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, the control assembly includes multiple liquid pressure plates 15; all the liquid pressure plates 15 are arranged in sequence along the contour direction of the radial section of the water tank 11, and the end of the liquid pressure plate 15 away from the liquid storage tank 13 can be rotated so that the other end can move towards or away from the direction of the first flange 111.

[0038] In this embodiment, the control assembly includes a plurality of pressure plates 15. The pressure plates 15 can be mounted within the water tank 11 via a support frame or other structure. A driving member can be provided at the rotating end of the pressure plates 15 to drive their rotation. The pressure plates 15 can be fan-shaped, with one end of the pressure plates 15 capable of swinging so that the swinging end can move closer to or further away from the first flange 111. The rising working fluid flow impacts the pressure plates 15, causing the swinging end of the pressure plates 15 to move away from the first flange 111, thereby allowing the working fluid to pass through the first flange 111 and enter the liquid storage tank 13. As the working fluid passes through the first flange 111 and enters the liquid storage tank 13, the electromagnet 14 at the first flange 111 absorbs magnetic impurities in the working fluid, resulting in filtrate entering the liquid storage tank 13. Under the action of the pressure plates 15, the working fluid level in the water tank 11 remains stable and the liquid level can be controlled, facilitating the electromagnet 14 to absorb magnetic impurities in the working fluid.

[0039] It is understood that in the filtration system provided in this embodiment, the control component can also be made of a soft cloth made of a flexible material, which can also achieve the purpose of slowing the flow of the working fluid and controlling the liquid level in this embodiment. Moreover, the liquid outlet end of the liquid inlet pipe 12 can also be arranged toward the inner wall of the water tank 11 or toward the liquid storage tank 13, which can also achieve the purpose of the working fluid discharged from the liquid outlet end of the liquid inlet pipe 12 in this embodiment having a tendency to flow toward the liquid storage tank 13.

[0040] The filtering system provided by the embodiment of the present invention is as follows: Figure 1As shown, it also includes a liquid separator 16 ; the liquid separator 16 is provided below the liquid outlet end of the liquid inlet pipe 12 , and the liquid separator 16 is used to allow the working fluid discharged from the liquid outlet end of the liquid inlet pipe 12 to flow around the liquid separator 16 .

[0041] In this embodiment, a liquid separator 16 is provided below the liquid outlet of the liquid inlet pipe 12. The liquid separator 16 is a conical structure that can diffuse the working fluid discharged from the liquid outlet of the liquid inlet pipe 12 to the surrounding areas, thereby achieving the purpose of uniform flow and at the same time promoting the upward flow of the working fluid. During use, the working fluid discharged from the liquid outlet of the liquid inlet pipe 12 will contact the liquid separator 16. At this time, large particles of magnetic impurities will sink to the lower end of the water tank 11 under the action of gravity, while small particles of magnetic impurities will rise with the working fluid and enter the first flange 111. In the process of the working fluid passing through the first flange 111 and entering the liquid storage tank 13, the small particles of magnetic impurities are adsorbed by the magnetic component at the first flange 111, thereby separating the magnetic impurities and allowing the filtrate to enter the liquid storage tank 13.

[0042] The filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, it also includes a liquid baffle 17; the liquid baffle 17 is a cylindrical structure, the liquid baffle 17 is arranged in the water tank 11, and the outer side of the liquid baffle 17 is spaced apart from the inner wall of the water tank 11; the liquid inlet pipe 12 is located in the liquid baffle 17, and the working fluid discharged from the liquid outlet end of the liquid inlet pipe 12 flows into the liquid storage tank 13 through the area between the liquid inlet pipe 12 and the liquid baffle 17.

[0043] In this embodiment, the liquid baffle 17 is a cylindrical structure having the same radial cross-sectional shape as the water tank 11. For example, if the water tank 11 is cylindrical, then the liquid baffle 17 is also cylindrical. The liquid baffle 17 serves to separate the inner wall of the water tank 11 from the rising working fluid, thereby preventing the rising working fluid from impacting the magnetic impurities attracted by the magnetic assembly when the magnetic assembly drives the magnetic impurities downward. In other words, the magnetic impurities attracted by the magnetic assembly are located in the gap between the inner wall of the water tank 11 and the liquid baffle 17.

[0044] The filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, it also includes a weighing component; the weighing component is used to monitor the weight information on and in the water tank 11; the controller is electrically connected to the weighing component, and the controller can control the current value of the electromagnet 14 according to the monitoring information of the weighing component.

[0045] In this embodiment, the weighing assembly works in conjunction with the magnetic assembly to prevent the magnetic assembly's adsorption effect from being affected. For example, the total weight M2 measured by the weighing assembly may be higher than the initial weight M1 of the device (assuming that the total volume V within water tank 11 remains approximately constant during operation). When total weight M2 exceeds 20% of M1, it indicates an excessive amount of magnetic impurities within water tank 11. Accelerating the downward movement of the magnetic impurities is necessary. This can be achieved by controlling the on / off frequency of electromagnet 14 and increasing the current flowing through electromagnet 14 via the controller.

[0046] The filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, it also includes an equipment bracket 181; the water tank 11 is arranged on the equipment bracket 181, and the weighing component includes a weighing sensor 182 arranged on the equipment bracket 181.

[0047] In the filtration system provided in this embodiment, a liquid level feedback device, such as a liquid level gauge, can be provided on the top of the water tank 11. In this way, combined with the liquid level in the water tank 11 and the weight information in the water tank 11 fed back by the weighing component, it can be predicted that when there are no other magnetic impurities adsorbed in the water tank 11, there is a proportional relationship between the liquid level in the water tank 11 and the weight in the water tank 11; since the magnetic impurities are mainly solid particles such as iron powder and iron oxide, whose density is significantly greater than the density of water, when a large amount of magnetic impurities are adsorbed on the bottom or side of the water tank 11, the overall weight of the water tank 11 will be significantly greater than the weight when there is only working fluid; at this time, it is necessary to accelerate the discharge of the magnetic impurities to the bottom of the water tank 11.

[0048] At the same time, in order to avoid magnetic interference between two adjacent magnetic blocks in the process of moving and transporting magnetic impurities in the magnetic component, which may cause some magnetic impurities to fail to move in the preset direction, in this embodiment, a certain distance needs to be set between the two adjacent magnetic blocks of the magnetic component. If the above-mentioned magnetic blocks are permanent magnets, an adjustment structure needs to be set to adjust the distance between the two adjacent permanent magnets to achieve the best effect; if the above-mentioned magnetic blocks are electromagnets 14, they can be adjusted according to the energized area of ​​the control magnet.

[0049] Preferably, a valve can be provided at the drain outlet 112 at the bottom of the water tank 11. The size of the valve at the drain outlet 112 can be controlled according to the amount of magnetic impurities obtained by monitoring the weight in the water tank 11 to avoid the accumulation of magnetic impurities and problems such as blockage, thereby meeting the sewage discharge speed and reducing the waste of working fluid.

[0050] Preferably, the position of the liquid separation plate 16 is adjustable, specifically, it can be adjusted in the direction of approaching or moving away from the liquid outlet end of the liquid inlet pipe 12, which can be achieved by setting a telescopic cylinder such as a pneumatic cylinder, an oil cylinder or an electric cylinder; when in use, it automatically rises or falls according to the impact force generated by the flow of the working fluid transported downward in the liquid inlet pipe 12, and dynamically adjusts the distance between the liquid outlet end of the liquid inlet pipe 12 and the liquid separation plate 16, so as to ensure that there is a certain resistance on all sides of the liquid separation plate 16 during liquid separation, ensure the uniformity of liquid separation on all sides, and maximize the volume utilization of the working fluid in the water tank 11.
