[0002] A flow measurement device is an instrument used to monitor the volume or mass flow rate of liquid in a pipeline in real time. Through the coordinated work of sensors, controllers and displays, and combined with parameters such as pressure and temperature, the flow rate is calculated. It is suitable for various liquids such as water, oil and chemical solutions. In industries such as petroleum, chemical and food, it can accurately measure liquid flow rate to optimize production ratios.

[0003] Existing flow measurement devices consist of connecting pipes, flanges, and flow measurement components. In use, the connecting pipes are connected to the delivery pipes via locking bolts and flanges, and the fluid flows through the connecting pipes. At this time, the flow measurement components can measure the fluid in the connecting pipes.

[0004] However, when the aforementioned flow measurement device measures the flow rate of the fluid, it cannot block or clean the impurities inside the fluid, which can cause blockages due to the accumulation of impurities when the fluid flows through the connecting pipe. Summary of the Invention

[0024] 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 protection scope of the present utility model.

[0025] Please see Figure 1 This utility model provides a technical solution: a flow measurement device with self-cleaning function, including a flow measurement component body 1 and a self-cleaning box 2. An inlet pipe 101 and an outlet pipe 102 are respectively provided on both sides of the flow measurement component body 1 for fluid flow.

[0026] When this utility model is in use, the fluid is guided to the flow measurement component body 1 through the inlet pipe 101 for flow measurement, and then discharged through the outlet pipe 102.

[0027] exist Figures 2-4 In the middle section: A self-cleaning box 2 is provided at the bottom of the inlet tube 101. An inlet tube 201, a return tube 1 202 and an outlet tube 203 are welded to the outside of the self-cleaning box 2. A connecting tube 2011 is provided on the upper side of the inlet tube 201. A return tube 2021 is provided on one side of the return tube 1 202. An interception net 1 204 is inserted into the inlet tube 101. A filter screen 205 is connected inside the self-cleaning box 2.

[0028] After the fluid enters the inlet pipe 101, it will be divided into two parts. One part flows directly through the inlet pipe 101 into the flow measurement component body 1, and the other part flows through the connecting pipe 2011, the inlet pipe 201, the self-cleaning box 2, the return pipe 1 202, and the return pipe 2 2021 until it returns to the inlet pipe 101. At this time, the fluid will come into contact with the interception net 1 204 and the filter screen 205. The interception net 1 204 and the filter screen 205 will intercept the impurities inside the fluid. The impurities intercepted by the interception net 1 204 will fall to the upper side of the filter screen 205 and accumulate at the filter screen 205 inside the self-cleaning box 2, thereby achieving the purpose of self-cleaning the fluid in the inlet pipe 101.

[0029] exist Figure 2 In the middle section: the ends of the connecting pipe 2011 and the return pipe 2021 away from the self-cleaning box 2 are both welded to the inlet pipe 101 for fluid conduction. A sealing cap 2031 is provided on one side of the outlet pipe 203, and a blocking block 2041 is welded inside the inlet pipe 101.

[0030] This utility model uses the return pipe 2021 to guide excess fluid in the self-cleaning box 2 back to the inlet pipe 101 for circulation. The connecting pipe 2011 is used for guiding the fluid and transporting impurities in the fluid. When it is necessary to clean the inside of the self-cleaning box 2, the self-cleaning box 2 can be removed, and the sealing cover 2031 on one side of the outlet pipe 203 can be opened to pour out the impurities in the self-cleaning box 2. The blocking block 2041 inside the inlet pipe 101 is used to support the interception net 204.

[0031] exist Figure 4 In the middle section: both ends of the inlet pipe 101 and the outlet pipe 102, as well as the connection ends of the inlet pipe 201, the connecting pipe 2011, the first return pipe 202, the second return pipe 2021, the outlet pipe 203 and the sealing cover 2031, are all welded with flange bodies 3, and adjacent flange bodies 3 are connected by locking bolts. Sealing gaskets 301 are provided between the inlet pipe 201 and the connecting pipe 2011, between the first return pipe 202 and the second return pipe 2021, and between the outlet pipe 203 and the sealing cover 2031 to seal the connection.

[0032] In this utility model, the pipes are connected to each other and the outlet pipe 203 is connected to the sealing cap 2031 by the flange body 3 and the locking bolts. The connection ends are provided with sealing gaskets 301 to enhance the sealing effect, which makes the fluid leakage prevention effect better during use.

[0033] exist Figure 4 and Figure 5 In the middle section: An intercepting net 22 4 is installed inside the access pipe 201. The intercepting net 22 4 is connected to the intercepting net 1 204. The intercepting net 22 4 is a hollow frustum-shaped structure. The opening size at the bottom of the intercepting net 22 4 is smaller than the opening size at the top. Positioning posts 401 are welded at equal intervals on the outside of the intercepting net 22 4. Positioning grooves 402 are opened at equal intervals inside the access pipe 201. The outside of the positioning posts 401 is inserted into the positioning grooves 402.

[0034] The present invention has a hollow frustum-shaped intercepting net 24 with a lower opening size smaller than the upper opening size inside the inlet pipe 201. This net can guide impurities downward in a centered manner. By reducing the bottom opening of the intercepting net 24, it can prevent impurities from flowing back into the inlet pipe 101. Furthermore, the outer side of the intercepting net 24 is connected to the positioning groove 402 through the positioning post 401, which facilitates the disassembly and cleaning of the intercepting net 24.

[0035] exist Figure 4 In the middle: A drive motor 404 is installed on one side of the self-cleaning box 2 by connecting bolts. The output end of the drive motor 404 is connected to the stirring rack 403 through a coupling. The stirring rack 403 is located inside the self-cleaning box 2 and is used to break up the impurities inside the self-cleaning box 2.

[0036] The present invention starts the drive motor 404. The output end of the drive motor 404 drives the stirring frame 403 to rotate through the coupling. This can disperse the impurities inside the self-cleaning box 2 and prevent the impurities from accumulating on the upper side of the filter screen 205 and clogging the mesh of the filter screen 205, thereby ensuring the flow effect of the fluid inside the self-cleaning box 2 and the inlet pipe 101.

[0037] Working principle: When using this utility model, after the fluid enters the inlet pipe 101, it will be divided into two parts. One part flows directly through the inlet pipe 101 to the flow measurement component body 1, and the other part flows through the connecting pipe 2011, the inlet pipe 201, the self-cleaning box 2, the return pipe 1 202, and the return pipe 2 2021 until it returns to the inlet pipe 101. At this time, the fluid will come into contact with the interception net 1 204 and the filter screen 205. The interception net 1 204 and the filter screen 205 intercept the impurities inside the fluid. After cleaning, the fluid will be guided to the flow measurement component body 1 for measurement and then discharged through the discharge pipe 102. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
