Description

Technical Field

[0001] This utility model relates to the field of wastewater measurement equipment technology, and in particular to a high-protection flow meter for wastewater measurement. Background Technology

[0002] In municipal wastewater treatment plants, it can resist impurities and corrosive substances in wastewater, ensuring flow monitoring at inlets, aeration tanks, and other stages; in the field of industrial wastewater treatment, facing highly corrosive and high-particle wastewater from the chemical and metallurgical industries, it achieves stable measurement through corrosion-resistant materials; in food processing plants, food-grade materials can accurately measure the flow rate of wastewater containing oil and suspended solids.

[0003] In the existing technology, some sewage flow meters have a certain degree of corrosion resistance and can resist a certain degree of sewage splash and dust. In terms of measurement principle, electromagnetic and ultrasonic flow meters are widely used. Electromagnetic flow meters use the principle of electromagnetic induction to measure the flow of conductive liquids, while ultrasonic flow meters achieve non-contact measurement through the time difference method.

[0004] However, in actual use, the inability to achieve effective protection will lead to the measuring electrodes being corroded and blocked by sewage, resulting in inaccurate measurement data. Internal electronic components are susceptible to moisture and electromagnetic interference damage, causing equipment failure. The failure of the outer casing seal allows sewage to seep in, increasing maintenance costs and safety hazards, making it difficult to meet the measurement needs in complex sewage environments. In response to the above problems, a high-protection flow meter for sewage measurement is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a high-protection flow meter for wastewater measurement, aiming to improve the problem that some existing wastewater measurement flow meters cannot achieve effective protection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-protection flow meter for wastewater measurement includes a measuring tube, with connecting flanges fixedly connected to the left and right sides of the outside of the measuring tube, an insulating lining fixedly connected to the inner wall of the measuring tube, a connecting block fixedly connected to the outside of the measuring tube, a device body detachably connected to the top of the connecting block, a protective mechanism fixedly connected to the outside of the device body, and a quick-release mechanism fixedly connected to the outside of the connecting block.

[0008] The protective mechanism includes a buffer rod, which is fixedly connected to the outside of the device body. A connecting rod is fixedly connected to the outside of the buffer rod, and a protective shell is fixedly connected to the outside of the buffer rod.

An annular scraper is slidably connected to the inside of the insulating liner, and a connecting block is fixedly connected to the inside of the annular scraper.

[0009] As a further description of the above technical solution:

[0010] The drive assembly includes a motor, which is fixedly connected to the outside of the measuring tube. A connecting rod is fixedly connected to the drive end of the motor, and a crank is fixedly connected to the outside of the connecting rod.

[0011] As a further description of the above technical solution:

[0012] The limiting component includes a guide sleeve, the outside of which is fixedly connected to the outside of the connecting rod, a follower rod fixedly connected to the outside of the guide sleeve, and a limiting block fixedly connected to the inside of the insulating lining.

[0013] As a further description of the above technical solution:

[0014] The limiting block is internally slidably connected to a follower rod, and the follower rod is externally fixedly connected to a connecting block on its left side.

[0015] As a further description of the above technical solution:

[0016] The quick-release mechanism includes a connecting tube, the outside of which is fixedly connected to the inside of the measuring tube, and a sealing gasket is fixedly connected to the outside of the connecting tube.

[0024] 1. In this utility model, the motor drives the connecting rod to move, which in turn drives the crank to move the follower rod, which in turn drives the buffer rod to move the connecting rod. As a result, the scraper can remove dirt and impurities from the electrode surface in real time, preventing them from affecting the measurement signal, controlling the error to a very small range, avoiding fiber entanglement and blockage caused by crystallization and scaling. With its corrosion-resistant shell, it resists sewage corrosion and environmental interference, ensuring that the flow meter can operate reliably for a long time in harsh sewage environments.

[0032] 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.

[0033] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a high-protection flow meter for sewage measurement, comprising a measuring tube 1. The measuring tube 1 is a hollow cylindrical structure with open ends, capable of withstanding the high-pressure environment during sewage transportation and resisting the erosion of corrosive substances in sewage. Connecting flanges 2 are fixedly connected to the left and right sides of the outside of the measuring tube 1. The connecting flanges 2 are annular disc structures with multiple bolt holes evenly distributed on their surface to ensure a stable connection between the measuring tube 1 and the sewage transportation pipeline and prevent sewage leakage. An insulating lining 3 is fixedly connected to the inner wall of the measuring tube 1. The insulating lining 3 is tightly attached to the inner wall of the measuring tube 1, which not only provides good insulation but also effectively isolates the sewage from direct contact with the metal wall of the measuring tube 1, further enhancing the corrosion resistance of the measuring tube 1. A connecting block 4 is fixedly connected to the outside of the measuring tube 1. A device body 5 is detachably connected to the top of the connecting block 4. A protective mechanism is fixedly connected to the outside of the device body 5, and a quick-release mechanism is fixedly connected to the outside of the connecting block 4.

[0034] The protective mechanism includes a buffer rod 6, which is externally fixed to the outside of the device body 5. The buffer rod 6 is vertically fixed to the outer surface of the device body 5. When the device body 5 is subjected to external collision or vibration, it can absorb the impact force through its own elastic deformation to protect the precision electronic components inside the device body 5. A connecting rod 7 is externally fixed to the buffer rod 6, and a protective shell 8 is externally fixed to the buffer rod 6. Multiple measuring electrodes 9 are fixedly connected to the inner wall of the insulating lining 3. The measuring electrodes 9 have a sheet-like structure and are evenly distributed along the circumference of the inner wall of the insulating lining 3. They are used to sense the electrical signal generated by the sewage flow, thereby realizing the accurate measurement of sewage flow. A drive assembly is externally fixed to the measuring tube 1, a limit assembly is internally fixed to the insulating lining 3, an annular scraper 17 is slidably connected to the insulating lining 3, and a connecting block 16 is fixedly connected to the annular scraper 17. The drive assembly includes a motor 10.

[0035] The motor 10 is externally fixedly connected to the outside of the measuring tube 1. The drive end of the motor 10 is fixedly connected to the connecting rod 11, and the outside of the connecting rod 11 is fixedly connected to the crank 12. When the motor 10 starts, the connecting rod 11 drives the crank 12 to rotate, thereby converting the rotational motion of the motor 10 into the linear motion of other components. The limiting component includes a guide sleeve 13, which can guide and support the movement of the connecting rod 11, ensuring that the connecting rod 11 remains stable during rotation and does not shake. The outside of the guide sleeve 13 is fixedly connected to the outside of the connecting rod 11, and the outside of the guide sleeve 13 is fixedly connected to the follower rod 14. The inside of the insulating lining 3 is fixedly connected to the limiting block 15, and the inside of the limiting block 15 is slidably connected to the follower rod 14. The left side of the outside of the follower rod 14 is fixedly connected to the connecting block 16.

[0036] Reference Figure 1 , Figure 2 , Figure 3 The quick-release mechanism includes a connecting pipe 18. The connecting pipe 18 not only provides an installation base for subsequent components, but also enhances the local structural strength of the measuring pipe 1 to a certain extent, ensuring the stability of the entire flow meter during sewage measurement. The external fixed connection of the connecting pipe 18 is to the inside of the measuring pipe 1. A sealing gasket 19 is fixedly connected to the external connection of the connecting pipe 18. The sealing gasket 19 is an annular thin sheet structure with an inner diameter slightly larger than the outer diameter of the connecting pipe 18. The outer diameter matches the mounting groove on the outside of the connecting pipe 18. During installation, the sealing gasket 19 is compressed to fill the tiny gaps between the connecting pipe 18 and the external components, forming a tight seal, effectively preventing sewage leakage and ensuring the normal operation of the flow meter in harsh environments. A flange ring 20 is fixedly connected to the external connection of the connecting pipe 18. The flange ring 20 is a thick annular metal disc with multiple internal threaded holes evenly distributed on its outer circumference. Multiple bolts 21 are connected to the external threads of the flange ring 20, and the bolt shank of the bolt 21 passes through the internal threaded hole of the flange ring 20.

[0037] When the device body 5 needs to be installed, tightening the bolt 21 will tightly connect flange ring 20 and flange ring 22 together. When disassembling, loosening the bolt 21 will quickly separate the two flange rings, making it easy to disassemble and assemble the device body 5. Flange ring 22 is fixedly connected to the bottom of the device body 5. Multiple nuts 23 are fixedly connected to the bottom of flange ring 22. The nuts 23 are welded below the through hole at the bottom of flange ring 22 and are used in conjunction with the bolt 21. After the bolt 21 passes through the through hole of flange ring 20 and flange ring 22, the nut 23 is screwed in. Through the thread engagement of the two, flange ring 20 and flange ring 22 are tightly fixed, thereby ensuring that the device body 5 is stably installed on the measuring tube 1. Multiple buffer rods 6 are fixedly connected to the outside of the device body 5. The buffer rods 6 are fixedly connected to the inside of the protective shell 8.

[0038] Working principle: The buffer rod 6 is embedded and fixed inside the protective shell 8. When the flow meter is put into use, the motor 10 starts and drives the connecting rod 11 to rotate. The crank 12 then makes a circular motion. Guided by the guide sleeve 13, the follower rod 14 makes a linear reciprocating motion in the limit block 15. Through the connecting block 16, the annular scraper 17 slides in the insulating lining 3 to clean the inner wall and the measuring electrode 9. At the same time, the sewage flows through the measuring tube 1. The measuring electrode 9 senses the electrical signal. After being processed by the device body 5, the sewage flow rate is accurately measured.

[0039] The connecting pipe 18 is fixed inside the measuring pipe 1, so that the sealing gasket 19 is fitted on the outside of the connecting pipe 18 and is compressed to fill the gap. The flange ring 20 is fixed outside the connecting pipe 18. The bolt 21 is passed through the internal thread hole of the flange ring 20. The flange ring 22 at the bottom of the device body 5 has a nut 23. The device body 5 is placed on the connecting block 4 so that the flange ring 20 and the flange ring 22 are aligned. The bolt 21 is tightened to engage with the nut 23, thereby realizing the quick installation and disassembly of the device body 5.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
