[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0026] As Figures 1-5 shown, a filtering mechanism for the production of oil-based suspending agents that is easy to clean includes a liquid inlet chamber 1, a filtering chamber 12 is opened at the bottom thereof, and a threaded hopper-shaped part 11 is provided at the connection between the liquid inlet chamber 1 and the filtering chamber 12;

[0027] A clear liquid outlet 2 is arranged on the axis of the liquid inlet chamber 1;

[0028] A filter pipe 21 is arranged at the bottom end of the clear liquid outlet 2 and located inside the filtering chamber 12;

[0029] A scraper 14 is rotatably arranged inside the filtering chamber 12 and is driven to move to clean the outer wall of the filter pipe 21.

[0030] Specifically, after the oil-based suspending agent enters the liquid inlet chamber 1, it is guided by the threaded hopper-shaped part 11 and flows along its inner wall. Since the threaded hopper-shaped part 11 is wider at the top and narrower at the bottom, the speed of the oil-based suspending agent is accelerated due to the narrowing of the inner diameter, forming a vortex in the filtering chamber 12. The impurities move in a circular motion with the vortex and are thrown towards the inner wall of the threaded hopper-shaped part 11 due to the centrifugal force. Since the pressure distribution along the radial direction is uneven when the liquid generates vortex motion, it is smaller closer to the axis and approaches zero at the axis. The filter pipe 21 is located inside the axis and is a low-pressure area, so that the oil-based suspending agent enters the filter pipe 21 under the action of the pressure difference. The large-particle impurities are intercepted by the filter holes opened on the filter pipe 21, and a suction mechanism is arranged at the clear liquid outlet 2 for extraction. The filtered oil-based suspending agent exits through the clear liquid outlet 2 and enters the next process. At the same time, the vortex generated by the oil-based suspending agent in the filtering chamber 12 will push the scraper 14 to rotate, so that the scraper 14 cleans the outer wall of the filter pipe 21 and scrapes off the intercepted impurities, and there is no need to specifically clean the filter pipe 21.

[0031] In the above technology, through the guidance of the threaded hopper-shaped part 11, the speed of the oil-based suspending agent is accelerated due to the narrowing of the inner diameter, forming a vortex in the filtering chamber 12. The oil-based suspending agent enters the filter pipe 21 under the action of the pressure difference, and the large-particle impurities are intercepted by the filter holes opened on the filter pipe 21. The filtered oil-based suspending agent exits through the clear liquid outlet 2, and while the scraper 14 rotates, it cleans the outer wall of the filter pipe 21 and scrapes off the intercepted impurities, and there is no need to specifically clean the filter pipe 21.

[0032] As a further embodiment provided by the present utility model, the filter tube 21 has a spiral structure that is wider at the top and narrower at the bottom.

[0033] Specifically, the spiral rotation direction of the filter tube 21 is the same as that of the threaded hopper portion 11. When the oil suspension agent forms a vortex, a low-pressure area appears at the axis, that is, at the position of the filter tube 21. Due to the pressure difference, the oil suspension agent actively enters. Subsequently, since the filter tube 21 is also a spiral structure, the oil suspension agent remains rotating inside it and is then drawn out through the clear liquid outlet 2, avoiding the increase in viscosity during the filtration process of the oil suspension agent. Moreover, the inner diameter of the connection between the filter tube 21 and the clear liquid outlet 2 decreases along the liquid outlet direction, so that the velocity of the liquid in the filter tube 21 increases when it enters the clear liquid outlet 2 due to the reduction of the inner diameter, improving the suction efficiency of the liquid outlet.

[0034] As a further embodiment provided by the present utility model, a guide rail 13 that can be slidably matched with the scraper 14 is arranged in the filtration chamber 12, and the guide rail 13 includes a low position and a high position;

[0035] Among them, the scraper 14 moves from the low position to the high position during the rotation stroke.

[0036] Specifically, a brush 142 is arranged on the side of the scraper 14 facing the filter tube 21, and a slider 141 that is slidably matched with the guide rail 13 is arranged on the side away from the filter tube 21. The guide rail 13 is composed of multiple parallel tracks. When the oil suspension agent flows along the threaded hopper portion 11, a vortex is generated, and the vortex drives the scraper 14 to rotate. Since the slider 141 and the guide rail 13 are slidably matched, the slider 141 moves from the low position to the high position of the guide rail 13 during the rotation process, so as to realize the upward movement of the scraper 14 while rotating, and the cleaning range of the filter tube 21 is larger. When the scraper 14 moves to the high position of the guide rail 13, the slider 141 disengages from the guide rail 13, so that the scraper 14 moves downward under the action of its own weight. Subsequently, the slider 141 is slidably matched with the guide rail 13 located below again and continues to slide along the guide rail 13 under the action of the vortex.

[0037] As a further embodiment provided by the present utility model, a folding elastic membrane 17 is arranged at the bottom of the filtration chamber 12, and the folding elastic membrane 17 is folded and deformed under the traction of the scraper 14.

[0038] Specifically, a movable ring 16 is rotatably arranged in the middle of the folding elastic membrane 17, and the movable ring 16 is fixedly connected to the scraping plate 14. When the slider 141 slides along the guide rail 13 from the low position to the high position, the scraping plate 14 rotates and moves upward, thereby driving the movable ring 16 to move upward, pulling and folding the folding elastic membrane 17 to deform and store elastic energy. After the slider 141 is separated from the guide rail 13, the elastic potential energy of the folding elastic membrane 17 is released, pulling the scraping plate 14 downward, and the impurities adhered to the bristles 142 are shaken off by the vibration generated during the pulling. At the same time, when the folding elastic membrane 17 is in the folded state, the upper surface will adhere to the filtered impurities. After the elastic potential energy is released, the folding elastic membrane 17 unfolds into a funnel-shaped part with a gradually narrowing inner diameter in a stepped manner, so that the impurities roll down along the upper surface to the narrow part under the action of their own weight, avoiding the adhesion and agglomeration of impurities on the surface of the folding elastic membrane 17.

[0039] As yet another embodiment further provided by the present utility model, a sewage collection cavity 15 is assembled at the bottom of the filtration cavity 12.

[0040] Specifically, impurities enter the sewage collection cavity 15 through the folding elastic membrane 17, and the sewage collection cavity 15 is assembled at the bottom of the filtration cavity 12 by bolts, which is convenient for disassembly. Moreover, due to the repeated folding and unfolding of the folding elastic membrane 17 at the port of the sewage collection cavity 15, the impurities in the sewage collection cavity 15 flow slowly, reducing the problem of agglomeration caused by long-term retention.

[0041] Working principle: After the oil suspending agent enters the liquid inlet cavity 1, it is guided by the threaded hopper-shaped part 11 and flows along its inner wall. Since the threaded hopper-shaped part 11 is wider at the top and narrower at the bottom, the speed of the oil suspending agent is accelerated due to the narrowing of the inner diameter, forming a vortex in the filtering cavity 12. The impurities move in a circular motion with the vortex and are thrown towards the inner wall of the threaded hopper-shaped part 11 due to centrifugal force. Since the pressure distribution along the radial direction is uneven when the liquid generates vortex motion, it is smaller closer to the axis and approaches zero at the axis. The filter tube 21 is located inside the axis and is a low-pressure area, so that the oil suspending agent enters the filter tube 21 under the action of the pressure difference, and the large-particle impurities are intercepted by the filter holes opened on the filter tube 21. Since the filter tube 21 is also a spiral structure, the oil suspending agent keeps rotating inside it and is then drawn out through the clear liquid outlet 2, avoiding the increase in viscosity during the filtering process of the oil suspending agent. Moreover, the inner diameter of the connection between the filter tube 21 and the clear liquid outlet 2 decreases along the liquid outlet direction, so that the speed of the liquid in the filter tube 21 increases due to the reduction of the inner diameter when entering the clear liquid outlet 2, improving the suction efficiency of the liquid outlet. At the same time, the vortex drives the scraper 14 to rotate. Since the slider 141 and the guide rail 13 are in sliding fit, the slider 141 moves from the low position to the high position of the guide rail 13 during the rotation process, so as to realize the upward movement of the scraper 14 while rotating, thereby driving the movable ring 16 to move upward, pulling and folding the folding elastic membrane 17 to deform and store elastic energy. The scraper 14 cleans the outer wall of the filter tube 21 and scrapes off the intercepted impurities. When the scraper 14 moves to the high position of the guide rail 13, the slider 141 disengages from the guide rail 13, and the elastic potential energy of the folding elastic membrane 17 is released, pulling the scraper 14 downward. The impurities adhered to the bristles 142 are shaken off by the vibration generated during the pulling. After the elastic potential energy is released, the folding elastic membrane 17 unfolds into a hopper-shaped part with a gradually narrowing stepped inner diameter, so that the impurities roll down along the upper surface towards the narrow part under the action of their own weight and enter the dirt collection cavity 15. The dirt collection cavity 15 is assembled at the bottom of the filtering cavity 12 by bolts, which is convenient for disassembly. Moreover, since the folding elastic membrane 17 repeatedly folds and unfolds at the port of the dirt collection cavity 15, the impurities in the dirt collection cavity 15 flow slowly, reducing the problem of agglomeration due to long-term retention, making the cleaning more convenient.

[0042] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
