Description

Technical Field

[0001] The present application relates to the technical field of liquid level gauges, and in particular to a magnetic flap liquid level gauge. Background Art

[0002] The magnetic flap level gauge is a product developed and produced based on the similar products at home and abroad and in accordance with the magnetic level gauge standard HG / T2158495 promulgated by the former Ministry of Chemical Industry. The instrument can be used for medium level detection of various towers, tanks, tanks, spherical containers, boilers and other equipment.

[0003] The existing patent (publication number: CN219914583U) discloses a flap magnetic float liquid level gauge, which relates to the technical field of flap type liquid level gauges and solves the technical problem that the existing technology cannot protect the magnetic float from colliding with the inner wall or forming resistance. The utility model includes a detection tube, which is a cylindrical tube body. A detection body is slidably installed in the detection tube, an indicator tube is fixedly installed on the front wall of the detection tube, and an indicator plate is rotatably installed in the indicator tube. The utility model causes the indicator plate to flip and indicate the liquid level through magnetic coupling when the magnetic float rises and falls in the liquid level. By setting a filtering structure at the front and the end, the liquid level space inside the liquid level gauge is kept pure and clean, which helps the magnetic float to move freely. The roller support of the side wall reduces the collision between the magnetic float and the side wall, improves the sensitivity of the magnetic float, and reduces the damage of the magnetic float. The contact plates and limit springs set at both ends indicate the liquid level, which is convenient for operators to set high and low liquid level alarms.

[0004] The above-mentioned liquid level meter is provided with filtering structures at the front and the end so that the internal liquid level space of the liquid level meter remains pure and clean, which helps the magnetic float to move freely. However, after a period of use, its filter element is prone to clogging, resulting in reduced liquid permeability, which greatly prolongs the lag of the liquid level of the liquid level meter compared to the internal liquid level of the container, affecting the monitoring effect. When replacing the filter element, it is often necessary to separate the liquid level meter from the external container, which is inconvenient. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a magnetic flap level gauge, which has the advantages of easy sewage discharge and filter element replacement, and solves the problem that the filter element is prone to clogging, resulting in reduced liquid permeability, thereby greatly prolonging the lag of the liquid level of the level gauge compared to the liquid level inside the container, affecting the monitoring effect. When replacing the filter element, it is often necessary to separate the level gauge from the external container, which is inconvenient.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a magnetic flap level gauge, comprising two connecting pipes, primary filter pipes are fixedly embedded in the left ends of the two connecting pipes, a plurality of distributed filter holes are opened on the right sides of the inner walls of the two primary filter pipes, and spiral sewage discharge sheets are arranged inside the two primary filter pipes;

[0007] The right ends of the two connecting pipes are fixedly inlaid with secondary filter pipes, the interiors of the two secondary filter pipes are slidably plugged with retaining frames, and the interior of each retaining frame is installed with a cylindrical filter element.

[0008] Through the above scheme, through the set filter holes and the secondary filtration of the cylindrical filter element, the replacement cycle of the cylindrical filter element can be effectively slowed down, and the convenience of the user is improved. By turning the hand wheel, the spiral sewage discharge plate can be driven to rotate, thereby achieving the effect of pushing the impurities adsorbed on the surface of the filter hole, which is convenient for the user to discharge larger impurities from the primary filter tube without disassembly. The replacement cover that is set can facilitate the user to quickly replace the cylindrical filter element, effectively improving the convenience of the user.

[0009] Furthermore, the right ends of the two connecting pipes are fixedly connected to the same liquid level meter body.

[0010] Through the above scheme, by setting the liquid level meter body, the purpose of monitoring the liquid level inside the external container can be achieved.

[0011] Furthermore, flanges are installed at the left ends of the two connecting pipes.

[0012] Through the above scheme, the flange is provided to facilitate the user to connect with the external container.

[0013] Furthermore, manual valves are installed inside the left ends of the two connecting pipes.

[0014] Through the above solution, by setting the manual valve, the purpose of closing the connecting pipe can be achieved.

[0015] Furthermore, the upper surfaces of the two primary filter tubes are rotatably connected to a power shaft, the top ends of the two power shafts are fixedly connected to a hand wheel, and each of the spiral sewage discharge plates is fixedly connected to the power shaft adjacent thereto.

[0016] Through the above scheme, the hand wheel is set to facilitate the user to rotate the spiral sewage discharge piece.

[0017] Furthermore, the bottoms of the two primary filter tubes are both threadedly connected with drain covers.

[0018] Through the above solution, the provision of the sewage discharge cover makes it convenient for users to release impurities.

[0019] Furthermore, the top ends of the two secondary filter tubes are both threadedly connected with replacement caps.

[0020] Through the above solution, by providing a replacement cover, it is convenient for users to replace the columnar filter element.

[0021] Furthermore, the outer surfaces of the two hand wheels are knurled.

[0022] According to the above solution, by providing knurling on the outer surface of the hand wheel, it is possible to prevent the user's hand from slipping during the rotation process.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This magnetic flap level gauge can effectively slow down the replacement cycle of the columnar filter element through the secondary filtration of the filter hole and the columnar filter element, and improve the convenience of users. By turning the hand wheel, the spiral sewage discharge plate can be driven to rotate, thereby achieving the effect of pushing impurities adsorbed on the surface of the filter hole, which is convenient for users to discharge larger impurities from the primary filter tube without disassembly. The replacement cover can be easily replaced by users quickly, which effectively improves the convenience of users. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] See also Figure 1 , Figure 3 and Figure 4 A magnetic flap level gauge in this embodiment includes two connecting tubes 1. The right ends of the two connecting tubes 1 are fixedly connected to the same level gauge body 8. Through the setting of the level gauge body 8, the purpose of monitoring the liquid level inside the external container can be achieved. Flanges 9 are installed at the left ends of the two connecting tubes 1. The setting of the flanges 9 facilitates the user to connect with the external container. Manual valves 11 are installed inside the left ends of the two connecting tubes 1. Through the setting of the manual valves 11, the purpose of closing the connecting tubes 1 can be achieved.

[0035] See also Figure 1 , Figure 2 and Figure 5 A primary filter tube 2 is fixedly embedded in the left ends of the two connecting tubes 1, and a drain cover 14 is threadedly connected to the bottom of the two primary filter tubes 2. The setting of the drain cover 14 facilitates the user to release impurities. A plurality of distributed filter holes 3 are provided on the right side of the inner wall of the two primary filter tubes 2. Spiral drain plates 4 are provided inside the two primary filter tubes 2. The upper surfaces of the two primary filter tubes 2 are rotatably connected to a power shaft 12, and the tops of the two power shafts 12 are fixedly connected to a hand wheel 13. Each spiral drain plate 4 is fixedly connected to the power shaft 12 adjacent to it, and the setting of the hand wheel 13 facilitates the user to rotate the spiral drain plate 4.

[0036] See also Figure 1 , Figure 2 and Figure 6 The right ends of the two connecting tubes 1 are fixedly inlaid with secondary filter tubes 5, and the interiors of the two secondary filter tubes 5 are slidably inserted with retaining frames 6. A cylindrical filter element 7 is installed inside each retaining frame 6. The top ends of the two secondary filter tubes 5 are threadedly connected with replacement covers 15. The setting of the replacement covers 15 can facilitate the user to replace the cylindrical filter elements 7. In addition, the outer surfaces of the two hand wheels 13 are knurled. The knurled outer surfaces of the hand wheels 13 can prevent the user from slipping during the rotation process.

[0037] A magnetic flap level gauge in the present embodiment can effectively slow down the replacement cycle of the columnar filter element 7 and improve the convenience of users by providing the filter hole 3 and the secondary filtration of the columnar filter element 7. By turning the hand wheel 13, the spiral sewage discharge plate 4 can be driven to rotate, thereby achieving the effect of pushing the impurities adsorbed on the surface of the filter hole 3, which is convenient for users to discharge larger impurities from the primary filter tube 2 without disassembly. The replacement cover 15 can facilitate users to quickly replace the columnar filter element 7, effectively improving the convenience of users.

[0038] It should be noted that when discharging sewage, the manual valve 11 is closed in advance to prevent the liquid inside the external container from being discharged through the connecting pipe 1.

[0039] The working principle of the above embodiment is as follows: when in use, the flange 9 is docked with the external container flange, and then the manual valve 11 is opened to allow the liquid to enter the liquid level meter body 8 through the connecting pipe 1, and the liquid level is monitored by the connecting vessel principle. When the liquid enters the liquid level meter body 8, it can filter and intercept larger impurities through the filter hole 3, and can filter smaller impurities through the columnar filter element 7. When the filter hole 3 is blocked, the manual valve 11 is closed, and then the drain cover 14 is opened, and the hand wheel 13 is turned to drive the spiral drain plate 4 to rotate, so that the filter hole 3 can be scraped, the impurities are transported downward, and the filter hole 3 is dredged. When the columnar filter element 7 needs to be replaced, the replacement cover 15 is opened, and then the retaining frame 6 is taken out, so that the columnar filter element 7 can be quickly replaced.
