[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, one embodiment of the present invention provides a new type of filtering system for filtering magnetic impurities in a working fluid; the new type of filtering 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 for adsorbing 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 enabling the adsorbed magnetic impurities to move toward the sewage outlet 112. The novel filtering 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 then is 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 needs to fill the water tank 11 first; 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. When the working fluid flows into the liquid storage tank 13, the magnetic component can absorb the magnetic impurities in the working fluid. Therefore, the filtrate after removing the magnetic impurities enters the liquid storage tank 13. 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. It is only necessary to clean the liquid storage tank 13 regularly. After being absorbed by the magnetic suction component, the magnetic impurities will move toward the drain port 112 at the lower end of the water tank 11 under the action of the magnetic suction component, and finally be discharged from the water tank 11 through the drain port 112 and recycled. By using the magnetic component to absorb the magnetic impurities in the working fluid by magnetic suction, and driving the magnetic impurities to move in the direction of the drain port 112 of the water tank 11, the separation of magnetic impurities is achieved; compared with the prior art, 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.

[0021] The novel 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.

[0022] In this embodiment, the water tank 11 is a cylindrical structure with an open top, and the upper edge of the water tank 11 is a frame at the open end; 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, and the first flange 111 is a part of the wall of the water tank 11, that is, the wall of the water tank 11 is divided into a flange section and a cylindrical section. The first flange 111 can be welded to the wall of the water tank 11 or formed in one piece; the liquid storage tank 13 is a disc-shaped structure, and its lower end surface is provided with a through hole, and the inner edge of the through hole is bent toward the inner side of the liquid storage tank 13 to form a second flange 131; the outer contour of the first flange 111 is completely consistent with 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. When in use, the working fluid enters the liquid storage tank 13 through the first flange 111, and the second flange 131 can separate the part of the liquid storage tank 13 storing the filtrate from the water tank 11.

[0023] The novel filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, the magnetic component includes a controller and a plurality of electromagnets 14 ; all the electromagnets 14 cover the tank wall of the water tank 11 , and any two electromagnets 14 are spaced apart; all the electromagnets 14 are electrically connected to the controller, and the controller is used to control the current value of the electromagnets 14 .

[0024] The magnetic assembly includes a controller and a plurality of electromagnets 14. The electromagnets 14 are arranged on the outer wall of the water tank 11, and all the electromagnets 14 can completely cover the outer wall of the water tank 11 (including the area of ​​the first flange 111); and any two electromagnets 14 are arranged at intervals to save costs; all the electromagnets 14 are electrically connected to the controller, and the controller is used to control the current value of the electromagnets 14, so that the electromagnets 14 can absorb magnetic impurities and transfer the magnetic impurities from one electromagnet 14 to another electromagnet 14 by controlling the power on and off of each electromagnet 14, so as to achieve the purpose of driving the magnetic impurities to move in the direction of 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 in the upper and lower parts. 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.

[0025] Optionally, in this embodiment, all the electromagnets 14 are divided into multiple adsorption groups, each adsorption group includes multiple electromagnets 14, and the electromagnets 14 in the same adsorption group are arranged at intervals on the outer wall of the water tank 11 along the circumference of the water tank 11; each adsorption group is arranged at intervals on the outer wall of the water tank 11 in sequence from the first flange 111 to the sewage outlet 112. By reasonably 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 electromagnet 14, and finally transferred to the sewage outlet 112 and discharged outward.

[0026] Moreover, in the present embodiment, as the magnetic impurities continue to move downward, the magnetic impurities at the lower end will accumulate. Therefore, as a preference, the frequency of switching the electromagnet 14 on and off is faster as it moves downward, and the current value when the electromagnet 14 is powered on is also larger. In this way, the magnetism of the electromagnet 14 is stronger, and more magnetic impurities can be adsorbed.

[0027] It can be understood that in this embodiment, the magnetic component can also include a conveyor chain and a plurality of permanent magnets; the conveyor chain is a closed structure formed by a plurality of chain links rotating in sequence, and permanent magnets are provided on two adjacent chain links or two chain links arranged at intervals. Through the cooperation of a motor and a plurality of 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.

[0028] The novel 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 .

[0029] In the present 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 upward at a very high speed, 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 arranged 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 new filtering system, such as Figure 1As shown, the control assembly also includes a control assembly; the control assembly is at least partially located above the first flange 111, and 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 height when the working fluid 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 above-mentioned working fluid, so that the liquid level of the water tank 11 can be stabilized, and at the same time, the liquid level height when the working fluid passes through the first flange 111 can be prevented from being too high, thereby improving the adsorption effect of the electromagnet 14 at the first flange 111. In addition, since the four sides of the upper end of the water tank 11 are connected to the liquid storage tank 13, the control assembly can also force the liquid to be evenly distributed, thereby ensuring the adsorption effect of the magnetic assembly.

[0030] Optionally, the novel filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, the control assembly includes a plurality of 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 one end of the liquid pressure plate 15 away from the liquid storage tank 13 can rotate so that the other end can move towards or away from the direction of the first flange 111.

[0031] In this embodiment, the control assembly includes a plurality of liquid pressure plates 15. The liquid pressure plates 15 can be arranged in the water tank 11 through structures such as a support frame, and a driving member can be arranged at the rotating end of the liquid pressure plates 15 to drive the liquid pressure plates 15 to rotate. The liquid pressure plates 15 can be in a fan-shaped structure, and one end of the liquid pressure plates 15 can swing so that the swinging end can be close to or away from the first flange 111; the rising working fluid flow impacts the liquid pressure plates 15 to make the swinging end of the liquid pressure plates 15 away from the first flange 111, so that the working fluid can pass through the first flange 111 and enter the liquid storage tank 13. When 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 the magnetic impurities in the working fluid, so that the liquid entering the liquid storage tank 13 is the filtrate. Under the action of the liquid pressure plates 15, the liquid level of the working fluid in the water tank 11 is stable, and the liquid level height can be controlled, which is conducive to the electromagnet 14 to absorb the magnetic impurities in the working fluid.

[0032] It is understandable that in the novel filtration system provided in this embodiment, the control component is also made of a soft cloth of a flexible material, which can also achieve the purpose of slowing down the flow of the working fluid and controlling the height of 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.

[0033] The novel 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 arranged below the liquid outlet end of the liquid inlet pipe 12 , and the liquid separator 16 is used to make the working liquid discharged from the liquid outlet end of the liquid inlet pipe 12 flow around the liquid separator 16 .

[0034] In this embodiment, a liquid separator 16 is further provided below the liquid outlet of the liquid inlet pipe 12. The liquid separator 16 is a conical structure, which can make the working liquid discharged from the liquid outlet of the liquid inlet pipe 12 diffuse to all sides, achieve the purpose of equal flow, and also promote the working liquid to flow upward. When in use, the working liquid 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 liquid and enter the first flange 111. In the process of the working liquid 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, so that the magnetic impurities are separated, and the filtrate enters the liquid storage tank 13.

[0035] The novel filtering system provided by the embodiment of the present invention is as follows: Figure 1 As shown, it also includes a liquid baffle plate 17; the liquid baffle plate 17 is a cylindrical structure, the liquid baffle plate 17 is arranged in the water tank 11, and the outer side of the liquid baffle plate 17 is spaced from the inner wall of the water tank 11; the liquid inlet pipe 12 is located in the liquid baffle plate 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 plate 17.

[0036] In this embodiment, the liquid baffle plate 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 a cylinder, the liquid baffle plate 17 is also a cylinder. The liquid baffle plate 17 is used 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 adsorbed by the magnetic component when the magnetic component drives the magnetic impurities downward. That is, the magnetic impurities adsorbed by the magnetic component are located in the gap between the inner wall of the water tank 11 and the liquid baffle plate 17.

[0037] The novel 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.

[0038] In this embodiment, the weighing component cooperates with the magnetic component to avoid affecting the adsorption effect of the magnetic component. For example, the total weight M2 detected by the weighing component will be higher than the initial weight M1 of the device (it can be assumed that when the device is working, the total volume V in the water tank 11 is roughly unchanged). When the total weight M2 exceeds 20% of M1, it means that the amount of magnetic impurities in the water tank 11 is too much. At this time, it is necessary to speed up the downward movement of the magnetic impurities, which can be achieved by controlling the frequency of the electromagnet 14 on and off and increasing the current value of the electromagnet 14 through the controller.

[0039] The novel 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.

[0040] In the novel filtering system provided in the present embodiment, a liquid level feedback device, such as a liquid level gauge, can be provided on the top of the water tank 11. Thus, in combination 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.

[0041] 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, thereby causing some magnetic impurities to fail to move in the preset direction, in this embodiment, a certain distance needs to be set between two adjacent magnetic blocks of the magnetic component. If the above-mentioned magnetic blocks are permanent magnets, it is necessary to set an adjustment structure 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.

[0042] Preferably, a valve can be provided at the drain outlet 112 at the bottom of the water tank 11, and the size of the valve of 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.

[0043] 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 gas 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, thereby ensuring that there is a certain resistance on all sides of the liquid separation plate 16 when separating liquid, ensuring the uniformity of liquid separation on all sides, and maximizing the volume utilization of the working fluid in the water tank 11.
