Description

Technical Field

[0001] This utility model relates to the field of electromagnetic water meter technology, and in particular to an electromagnetic water meter that prevents scaling. Background Technology

[0002] An electromagnetic water meter is a metering device that uses the principle of electromagnetic induction to measure the flow rate of liquid in a pipeline. It mainly consists of a meter body, a converter, a controller, and other components. It is widely used in fluid transportation systems such as tap water and industrial wastewater, and features high measurement accuracy and fast response speed.

[0003] In practical use, traditional electromagnetic water meters are prone to scaling:

[0004] First, minerals and impurities such as calcium and magnesium in the water will deposit inside the meter (such as the casing and electrodes). Long-term accumulation will affect the transmission of electromagnetic induction signals, leading to a decrease in measurement accuracy.

[0005] Secondly, there is a lack of effective filtration and cleaning structures. Since the clogging of the filter components cannot be monitored in real time, the failure of the filter can easily lead to increased scaling. Impurities can easily adhere to the flow channels of the filter body. Furthermore, manual cleaning requires disassembling the equipment, which is cumbersome, affects normal water supply, and increases equipment maintenance costs. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides an anti-scaling electromagnetic water meter, which overcomes the shortcomings of the prior art and effectively solves the problem of easy scaling in traditional electromagnetic water meters.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An anti-scaling electromagnetic water meter includes a meter body. An inlet pipe is fixedly connected to the outer wall of one end of the meter body via a flange, and an outlet pipe is fixedly connected to the outer wall of the other end of the meter body via a flange. A front end pipe and a tail end pipe are fixedly connected to the bottom outer wall of the inlet pipe via a flange, and a filter cylinder is arranged between the front end pipe and the tail end pipe. A filter element is arranged inside the filter cylinder. A backwash pipe is fixedly connected to the bottom outer wall of the outlet pipe via a flange, and a backwash nozzle is arranged on the outer wall of one end of the backwash pipe. The backwash nozzle is located inside the filter element.

[0009] Preferably, the meter body includes a housing fixedly connected between the inlet pipe and the outlet pipe via a flange, a converter mounted on the top outer wall of the housing, and a controller mounted on the outer wall of one side of the converter.

[0010] Preferably, a first pressure gauge and a second pressure gauge are respectively installed on the outer walls of the front end tube and the tail end tube.

[0011] Preferably, a first valve is installed on the outer wall of the front end pipe above the first pressure gauge, a second valve is installed on the outer wall of the tail end pipe above the second pressure gauge, and a third valve is installed on the outer wall of the inlet pipe above the filter cylinder.

[0012] Preferably, a fourth valve is installed on the outer wall of the backflushing pipe, and a drain pipe is provided on the outer wall of the bottom of the filter cylinder, and a fifth valve is installed on the outer wall of the drain pipe.

[0013] Preferably, the inner wall of the filter cylinder is provided with a water-permeable plate and a sealing cover at both ends, and the filter element is installed between the water-permeable plate and the sealing cover.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The anti-scaling electromagnetic water meter designed in this way can filter the water entering the meter body by setting a filter cylinder and an internal filter element, intercepting impurities and particles in the water, reducing the deposition of impurities in the meter body, and reducing the probability of scaling from the source. At the same time, the first pressure gauge and the second pressure gauge on the front end pipe and the tail end pipe can monitor the pressure difference on both sides of the filter element in real time, which makes it easy to detect the filter element blockage in time, and solves the problem of inaccurate measurement caused by impurity deposition in traditional water meters.

[0016] 2. The anti-scaling electromagnetic water meter designed in this way has a backwash nozzle located inside the filter element. The water flow through the outlet pipe backwashes the filter element, which can remove the impurities attached to the filter element. Cleaning can be completed without disassembly. With the help of the drain pipe and the fifth valve, the sewage generated during rinsing can be discharged in time, avoiding secondary pollution from impurities. This solves the defects of traditional water meters, such as cumbersome cleaning and high maintenance costs, and extends the service life of the equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 Example 1: An anti-scaling electromagnetic water meter includes a meter body 1. One end of the meter body 1 is fixedly connected to an inlet pipe 2 via a flange, and the other end of the meter body 1 is fixedly connected to an outlet pipe 3 via a flange. The bottom outer wall of the inlet pipe 2 is fixedly connected to a front end pipe 4 and a tail end pipe 5 via a flange. A filter cylinder 6 is provided between the front end pipe 4 and the tail end pipe 5, and a filter element 7 is provided inside the filter cylinder 6.

[0024] The meter body 1 is connected to the inlet pipe 2 and the outlet pipe 3 via flanges. The front end pipe 4 and the rear end pipe 5 at the bottom of the inlet pipe 2 form a bypass filtration structure with the filter cartridge 6. The filter element 7 inside the filter cartridge 6 is installed between the permeable baffle 18 and the sealing cover 19. The permeable baffle 18 allows water to flow through and prevents the filter element 7 from shifting, while the sealing cover 19 ensures that the water flow is completely filtered by the filter element 7. When water flows through the inlet pipe 2, the water can enter the filter cartridge 6 through the front end pipe 4, and after being filtered by the filter element 7, it returns to the inlet pipe 2 from the rear end pipe 5, effectively intercepting impurities and protecting the internal components of the meter body 1.

[0025] In this embodiment, by setting the filter cylinder 6 and the internal filter element 7, the water flowing into the meter body 1 can be filtered, intercepting impurities and particles in the water, reducing the deposition of impurities in the meter body 1, and reducing the probability of scaling from the source. At the same time, the first pressure gauge 10 and the second pressure gauge 11 on the front end pipe 4 and the tail end pipe 5 can monitor the pressure difference on both sides of the filter element 7 in real time, which makes it easy to detect the blockage of the filter element 7 in time, and solves the problem of inaccurate measurement caused by impurity deposition in traditional water meters.

[0026] In embodiment 2, a backwash pipe 8 is fixedly connected to the bottom outer wall of the water outlet pipe 3 via a flange, and a backwash nozzle 9 is provided on the outer wall of one end of the backwash pipe 8. The backwash nozzle 9 is located inside the filter element 7.

[0027] One end of the backwash pipe 8 at the bottom of the water outlet pipe 3 is connected to the backwash nozzle 9, and the backwash nozzle 9 extends into the filter element 7. When the filter element 7 becomes clogged, the third valve 14 can be closed and the fourth valve 15 can be opened. The water flow in the water outlet pipe 3 enters the backwash nozzle 9 through the backwash pipe 8 to backwash the filter element 7, washing off the impurities attached to the filter element 7, thus achieving online cleaning of the filter element 7 without disassembling the filter cartridge 6, making the operation convenient.

[0028] In this embodiment, the backwash nozzle 9 is located inside the filter element 7. The filter element 7 is backwashed by the water flow through the outlet pipe 3, which can remove the impurities attached to the filter element 7. Cleaning can be completed without disassembly. With the help of the drain pipe 16 and the fifth valve 17, the sewage generated by the flushing can be discharged in time, avoiding secondary pollution from impurities. This solves the defects of traditional water meter cleaning being cumbersome and having high maintenance costs, and extends the service life of the equipment.

[0029] The meter body 1 includes a housing 101 fixedly connected between the water inlet pipe 2 and the water outlet pipe 3 by a flange, a converter 102 installed on the top outer wall of the housing 101, and a controller 103 installed on one side outer wall of the converter 102.

[0030] The housing 101 of the meter body 1 serves as a water flow channel. The converter 102 on the top of the housing 101 converts the electromagnetic induction signal into flow data, and the controller 103 is used to display and transmit the data.

[0031] A first pressure gauge 10 and a second pressure gauge 11 are respectively installed on the outer walls of the front end pipe 4 and the tail end pipe 5. A first valve 12 is installed on the outer wall of the front end pipe 4 above the first pressure gauge 10, and a second valve 13 is installed on the outer wall of the tail end pipe 5 above the second pressure gauge 11. A third valve 14 is installed on the outer wall of the water inlet pipe 2 above the filter cylinder 6.

[0032] The first valve 12 of the front end pipe 4 and the second valve 13 of the tail end pipe 5 can control the opening and closing of the filter branch. The third valve 14 of the inlet pipe 2 is used to adjust the water flow distribution between the branch and the main filter, which facilitates the separate maintenance of the filter system.

[0033] A fourth valve 15 is installed on the outer wall of the backwash pipe 8, and a drain pipe 16 is provided on the bottom outer wall of the filter cylinder 6. A fifth valve 17 is installed on the outer wall of the drain pipe 16. A water-permeable plate 18 and a sealing cover 19 are respectively provided at both ends of the inner wall of the filter cylinder 6, and the filter element 7 is installed between the water-permeable plate 18 and the sealing cover 19.

[0034] The fourth valve 15 on the backwash pipe 8 controls the flow of backwash water. The drain pipe 16 and the fifth valve 17 at the bottom of the filter cartridge 6 are used to discharge the wastewater generated during rinsing. When backwashing is performed, the fifth valve 17 is opened, and the impurities washed off the filter element 7 can be discharged from the drain pipe 16 along with the wastewater, ensuring that the inside of the filter cartridge 6 is clean.

[0035] Working principle: When the device is working normally, water flows through the front pipe 4 (first valve 12 is open) into the filter cylinder 6, and after being filtered by the filter element 7, it returns to the inlet pipe 2 through the tail pipe 5 (second valve 13 is open). The filtered water flows into the housing 101 of the meter body 1. The converter 102 measures the flow rate through electromagnetic induction, and the data is processed and displayed by the controller 103.

[0036] When the pressure difference between the first pressure gauge 10 and the second pressure gauge 11 exceeds the set value, it indicates that the filter element 7 is clogged. At this time, close the first valve 12 and the second valve 13, and open the third valve 14 and the fourth valve 15. The water flow briefly stops passing through the filter cartridge 6. The water in the outlet pipe 3 flows through the backwash pipe 8 and sprays out from the backwash nozzle 9 to backwash the filter element 7. The impurities washed off are discharged with the sewage from the drain pipe 16. After cleaning, continue to open the first valve 12 and the second valve 13, and close the third valve 14, the fourth valve 15 and the fifth valve 17. The device returns to normal filtration status.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
