Description

Technical Field

[0001] This utility model relates to the field of shielded pump technology, specifically a filter clogging monitoring device for the pump inlet of a shielded pump. Background Technology

[0002] A canned motor pump is a seal-free pump in which both the pump and the drive motor are sealed within a pressure vessel filled with the pumped medium. This pressure vessel has only a static seal, and a rotating magnetic field is provided by an electrical wiring harness to drive the rotor. This structure eliminates the rotating shaft sealing device found in traditional centrifugal pumps, thus achieving complete leak-free operation. Canned motor pumps are specially equipped with circulation pipes to cool and lubricate the bearings, rotor, stator, and shielding sleeves of the canned motor pump.

[0003] The utility model patent with publication number CN219993999U, entitled "A Shielded Pump with a Circulation Pipe and Filter," relates to the field of shielded pump technology. It includes a shielded pump body, a circulation pipe, and a shielded pump base. A filter is fixedly installed on one end of the left side of the shielded pump body, and the outer wall of the filter is fixedly connected to one end of the circulation pipe. This utility model filters impurities in the coolant through a filter screen. When there are too many impurities on the filter screen, reducing the conveying efficiency, rotating a knob rotates a threaded rod, causing a moving plate to descend and engage a baffle plate inside the circulation pipe to prevent coolant delivery. Then, pulling a pull block uses a fixed plate to pull out the filter screen for cleaning. This solves the problem in existing shielded pumps where impurities in the conveyed coolant cause wear on the bearing rotor, impurity accumulation and blockage, and reduced conveying efficiency. It achieves the goal of filtering coolant impurities, facilitating cleaning, and preventing blockage of the internal rotor of the shielded pump, thus avoiding impact on the conveying effect.

[0004] Existing canned pumps are equipped with filters during use, but the filter components are installed inside, which requires regular cleaning during use. It is difficult to clean the filter according to the filtration status, resulting in a reduction in the filter's working efficiency.

[0005] Therefore, a filter clogging monitoring device for the pump inlet of a shielded pump is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A filter clogging monitoring device for a shielded pump inlet, comprising a base, with a shielded pump body approximately located on the top of the base; a first connecting flange fixedly connected to the end of the shielded pump body; a filter body disposed at the end of the first connecting flange; a pair of connecting sleeves fixedly connected to the end of the filter body; a second connecting flange fixedly connected to the end of the connecting sleeves; the filter body and the base are in communication; the second connecting flange and the first connecting flange are connected by multiple bolts; a cylinder fixedly connected to the top of the connecting sleeves; a hydrogen balloon slidably connected inside the cylinder; and a hydrogen balloon fixedly connected to the bottom of the cylinder. A connecting rope is attached; the connecting rope is slidably connected through the connecting sleeve; a foam ball is fixed to the bottom of the connecting rope; by adding a pair of foam balls and a hydrogen balloon, the floating state of the hydrogen balloon can pull the foam ball upward when the coolant passes by, and then the coolant pushes the foam ball to move the hydrogen balloon downward. When the hydrogen balloon moves downward, it will show the pushing resistance of the coolant on the foam ball. From this, it can be judged whether the degree of pushing resistance of the coolant on the foam ball causes the hydrogen balloon to move downward is consistent. If they are consistent, it means that the filter body is not blocked and the flow is not affected. At the same time, the cylinder can guide the movement path of the hydrogen balloon, and at the same time, it can reduce the impact of external wind on the hydrogen balloon.

[0008] Preferably, a pointer is fixed to the top of the connecting sleeve; the pointer is located in the middle of the cylinder; the hydrogen balloon and the pointer are connected through each other; a pair of scale lines are fixed to the side wall of the cylinder; the scale lines and the pointer are connected and are inclined on the cylinder; by adding the pointer and scale lines, the corresponding positions can be recorded, which makes visual judgment more convenient and improves the visual effect when judging the hydrogen balloon.

[0009] Preferably, an oil-absorbing sponge is fixed to the top of the hydrogen balloon; multiple oil injection pipes are provided on the surface of the cylinder; by adding the oil-absorbing sponge, some oil can be stored, thereby lubricating the surface of the connecting rope when it comes into contact with the oil-absorbing sponge, thereby reducing friction when the connecting rope comes into contact with the connecting sleeve, thus increasing the protection of the connecting rope and extending its service life.

[0010] Preferably, a sign is fixed to the side wall of the cylinder; the sign and the cylinder are correspondingly set; by adding the sign, a reminder of the normal flow rate can be added, thereby providing a corresponding location indication of the normal flow rate.

[0011] Preferably, a guide rod is fixedly connected inside the connecting sleeve; the foam ball is through-mounted and slidably connected to the guide rod; by adding the guide rod, the foam ball can be restricted, making the foam ball more stable when pushed.

[0012] Preferably, a cover plate is slidably fitted to the top of the cylinder; the cover plate has multiple air holes in the middle; by adding the cover plate, impurities at the top of the cylinder can be intercepted, reducing the impact of falling into the cylinder on the hydrogen balloon, thereby increasing the protection of the hydrogen balloon.

[0013] The advantages of this utility model are:

[0014] 1. The present invention discloses a filter clogging monitoring device for a shielded pump inlet. By adding a pair of foam balls and a hydrogen balloon, the floating state of the hydrogen balloon pulls the foam balls upward when the coolant passes through. Then, the coolant pushes the foam balls, causing the hydrogen balloon to move downward. When the hydrogen balloon moves downward, it shows the pushing resistance of the coolant on the foam balls. From this, it can be determined whether the degree of pushing resistance of the coolant on the foam balls causes the hydrogen balloon to move downward is consistent. If they are consistent, it means that the filter body is not clogged and the flow rate is not affected. At the same time, the cylinder can guide the movement path of the hydrogen balloon and reduce the impact of external wind on the hydrogen balloon.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a filter clogging monitoring device for a canned motor pump inlet includes a base 1, with a canned motor pump body 11 approximately mounted on the top of the base 1; a first connecting flange 12 is fixedly connected to one end of the canned motor pump body 11; a filter body 15 is disposed at one end of the first connecting flange 12; a pair of connecting sleeves 14 are fixedly connected to one end of the filter body 15; a second connecting flange 13 is fixedly connected to one end of the connecting sleeves 14; the filter body 15 and the base 1 are in communication; the second connecting flange 13 and the first connecting flange 14 are connected to the base 1. The flange 12 is connected by multiple bolts; a cylinder 16 is fixedly connected to the top of the connecting sleeve 14; a hydrogen balloon 17 is slidably connected inside the cylinder 16; a connecting rope 18 is fixedly connected to the bottom of the hydrogen balloon 17; the connecting rope 18 is slidably connected through the connecting sleeve 14; a foam ball 19 is fixedly connected to the bottom of the connecting rope 18; during operation, the coolant inside the shielded pump body 11 passes through the connecting sleeve 14 before passing through the filter body 15. When passing through, the coolant pushes the foam ball 19 closer to the filter body 15. Simultaneously, when foam ball 19 is pushed, it will cause hydrogen balloon 17 to move downwards via connecting rope 18. Afterwards, the coolant, after passing through filter body 15, will come into contact with foam ball 19 on the other side. At this time, the coolant will push foam ball 19 on the other side, and foam ball 19 will cause hydrogen balloon 17 to move downwards. Then, the height of the pair of hydrogen balloons 17 inside transparent cylinder 16 is observed and compared. By comparing the water flow on both sides, when the heights of the hydrogen balloons 17 are consistent, filter body 15 will not be blocked. By adding a pair of foam balls 19 and hydrogen balloons 17, the coolant can be lowered as it passes through... The floating state of the hydrogen balloon 17 pulls the foam ball 19 upward, and then the coolant pushes the foam ball 19 to move the hydrogen balloon 17 downward. When the hydrogen balloon 17 moves downward, it will show the pushing resistance of the coolant on the foam ball 19. From this, it can be judged whether the pushing resistance of the coolant on the foam ball 19 causes the hydrogen balloon 17 to move downward to the same extent. If they are the same, it means that the filter body 15 is not blocked and the flow is not affected. At the same time, the cylinder 16 can guide the movement path of the hydrogen balloon 17 and reduce the impact of external wind on the hydrogen balloon 17.

[0026] like Figures 2 to 4As shown, a pointer 2 is fixedly connected to the top of the connecting sleeve 14; the pointer 2 is located in the middle of the cylinder 16; the hydrogen balloon 17 and the pointer 2 are connected through each other; a pair of scale lines 21 are fixedly connected to the side wall of the cylinder 16; the scale lines 21 and the pointer 2 are connected and are inclined on the cylinder 16; during operation, when the hydrogen balloon 17 moves inside the cylinder 16, the pointer 2 at the top will point to the scale line 21, so that the pointer 2 and the scale line 21 correspond. Thus, the position of the hydrogen balloon 17 can be quickly determined by the position of the pointer 2 and the scale line 21 on both sides, thereby speeding up the determination of the flow rate; by adding the pointer 2 and the scale line 21, the corresponding position can be recorded, which makes visual judgment more convenient and improves the visual effect when judging the hydrogen balloon 17.

[0027] like Figure 3 As shown, an oil-absorbing sponge 3 is fixed to the top of the hydrogen balloon 17; multiple oil injection pipes 31 are provided on the surface of the cylinder 16; during operation, a syringe is used to inject water-insoluble lubricating oil into the oil injection pipes 31. When the lubricating oil enters the oil injection pipe 31, it slides along the oil injection pipe 31 to the oil-absorbing sponge 3, where it is absorbed. After absorption, the lubricating oil adheres to the surface of the connecting rope 18 when it slides, thereby reducing the friction when the connecting rope 18 contacts the connecting sleeve 14. By adding the oil-absorbing sponge 3, some oil can be stored, thereby lubricating the surface of the connecting rope 18 when it contacts the oil-absorbing sponge 3, thus reducing the friction when the connecting rope 18 contacts the connecting sleeve 14, thereby increasing the protection of the connecting rope 18 and extending its service life.

[0028] like Figures 4 to 5 As shown, a sign 4 is fixed to the side wall of the cylinder 16; the sign 4 and the cylinder 16 are set in a corresponding manner; during operation, when judging the hydrogen balloon 17, the positions of the hydrogen balloon 17 and the sign 4 can be observed. When the hydrogen balloon 17 is in the position corresponding to the sign 4, it represents the normal flow rate; when they are inconsistent, it represents the abnormal flow rate; by adding the sign 4, the reminder of the normal flow rate can be increased, thereby providing a corresponding position prompt for the normal flow rate.

[0029] like Figure 4 As shown, a guide rod 5 is fixedly connected inside the connecting sleeve 14; the foam ball 19 is through-mounted and slidably connected to the guide rod 5; during operation, when the foam ball 19 is pushed by the coolant, the foam ball 19 will slide along the surface of the guide rod 5, thereby increasing the stability of the guide rod 5 during movement and reducing the shaking of the foam ball 19 when it is pushed; by adding the guide rod 5, the foam ball 19 can be restricted, making the foam ball 19 more stable when it is pushed.

[0030] like Figures 1 to 5As shown, a cover plate 6 is slidably fitted on the top of the cylinder 16; the cover plate 6 has multiple air holes 61 in the middle; during operation, the cover plate 6 is placed on top of the cylinder 16 to close the top of the cylinder 16, thereby reducing the amount of impurities falling into the cylinder 16 from the top, and the air holes 61 can reduce the impact on the upward movement of the hydrogen balloon 17; by adding the cover plate 6, impurities can be intercepted at the top of the cylinder 16, reducing the impact of falling into the cylinder 16 on the hydrogen balloon 17, thereby increasing the protection of the hydrogen balloon 17.

[0031] Working principle: During operation, the coolant inside the shielded pump body 11 passes through the connecting sleeve 14 before passing through the filter body 15. As it passes, the coolant pushes the foam ball 19 closer to the filter body 15. Simultaneously, the foam ball 19, being pushed, causes the hydrogen balloon 17 to descend via the connecting rope 18. After passing through the filter body 15, the coolant comes into contact with the foam ball 19 on the other side, pushing it further. This, in turn, causes the hydrogen balloon 17 to descend. The height of the pair of hydrogen balloons 17 inside the transparent cylinder 16 is then compared to the water flow on both sides. When the heights of the hydrogen balloons 17 are consistent, the filter body 15 is not blocked. As the hydrogen balloon 17 moves inside the cylinder 16, the top indicator 2 points to the scale line 21, aligning the indicator 2 with the scale line 21. This allows for quick determination of the hydrogen balloon 17's position, thus accelerating flow rate assessment. During use, an insoluble lubricating oil is injected into the oil injection tube 31 using a syringe. When the lubricating oil enters the oil injection tube 31, it slides along the oil injection tube 31 to the oil-absorbing sponge 3, where it is absorbed. After absorption, the lubricating oil adheres to the surface of the connecting rope 18 as it slides, thus reducing friction when the connecting rope 18 and the connecting sleeve 14 come into contact. When judging the hydrogen balloon 17, the positions of the hydrogen balloon 17 and the sign 4 can be observed. When the hydrogen balloon 17 is in the position corresponding to the sign 4, it represents a normal flow rate; otherwise, it represents an abnormal flow rate. When the foam ball 19 is pushed by the coolant, it slides along the surface of the guide rod 5, which increases the stability of the guide rod 5 during movement and reduces the shaking of the foam ball 19 when it is pushed. During use, the cover plate 6 is placed on top of the cylinder 16 to close the top of the cylinder 16, thereby reducing the amount of impurities falling from the top of the cylinder 16. At the same time, opening the vent 61 can reduce the impact on the upward movement of the hydrogen balloon 17.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
