Description

Technical Field

[0001] This utility model relates to the field of liquid turbine flow meters, and in particular to a liquid turbine flow meter with self-cleaning function. Background Technology

[0002] A liquid turbine flow meter is an instrument that uses the rotation of turbine blades to measure the flow rate of fluid. Its working principle is based on fluid dynamics. When liquid flows through the turbine flow meter, it impacts the turbine blades, causing them to rotate. The speed of the turbine is proportional to the flow rate of the fluid. By measuring the speed of the turbine and then performing specific conversions and calculations, the flow rate of the fluid can be obtained.

[0003] When measuring liquids containing organic matter or in environments prone to microbial growth, turbine flow meters require extra cleaning. Organic matter easily adheres to the surfaces of components such as the turbine, bearings, and seals, affecting the normal rotation of the turbine and measurement accuracy. Excessive accumulation of these organic substances can even cause the turbine to seize or the seals to fail, rendering the flow meter malfunctioning. To clean a turbine flow meter, prepare clean, soft cloths, brushes, screwdrivers, and other tools to disassemble the flow meter components. Choose an appropriate cleaning agent for wiping, depending on the specific situation.

[0004] In the existing technology, turbine flow meters lack self-cleaning function. When turbine flow meters detect organic liquids for a long time, organic pollutants will adhere to the surface of the impeller or housing, requiring disassembly of the flow meter components for cleaning with cleaning agents. This leads to reduced cleaning efficiency, incomplete cleaning, cleaning agent residue, and other problems, resulting in high maintenance costs and long downtime. Therefore, a liquid turbine flow meter with self-cleaning function is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a liquid turbine flow meter with self-cleaning function, which aims to improve the problem that the existing liquid turbine flow meters with self-cleaning function lack photocatalytic self-cleaning function for organic pollutants, resulting in reduced cleaning effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a liquid turbine flow meter with self-cleaning function, comprising a housing, a counting device fixedly connected to the top of the housing, an impeller disposed on the inner wall of the housing, a shaft fixedly connected to the center of the impeller, a guide fixedly connected to the outer wall of the impeller, a titanium dioxide layer fixedly connected to the surface of the impeller, a fixing frame disposed inside the housing, a stainless steel filter plate fixedly connected to the inner wall of the fixing frame, a magnetic block fixedly connected to the side wall of the fixing frame, a waterproof magnetic seat fixedly connected to the inner wall of the housing, an insertion port opened on the surface of the waterproof magnetic seat, a converging ring fixedly connected to the side wall of the fixing frame, a fixing block fixedly connected to the outer wall of the converging ring, an ultraviolet lamp tube fixedly connected to the surface of the fixing block, an adjusting plate attached to the side wall of the stainless steel filter plate, and filter holes penetrating through the surface of the adjusting plate.

[0022] 1. In this utility model, by combining a titanium dioxide layer, a fixing frame, a stainless steel filter plate, an adjusting plate, a magnetic block, a waterproof magnetic seat, a converging ring, and an ultraviolet lamp, the introduced water source is first purified to reduce the degree of contamination of the impeller and the casing.

[0030] 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.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a liquid turbine flow meter with self-cleaning function, comprising a housing 1, a counting device 3 fixedly connected to the top of the housing 1, an impeller 2 disposed on the inner wall of the housing 1, a shaft 5 fixedly connected to the center of the impeller 2, a guide 4 fixedly connected to the outer wall of the impeller 2, a fixing frame 7 disposed inside the housing 1, a stainless steel filter plate 8 fixedly connected to the inner wall of the fixing frame 7, a magnetic block 9 fixedly connected to the side wall of the fixing frame 7, and a waterproof magnetic base 10 fixedly connected to the inner wall of the housing 1. The waterproof magnetic base 10 is magnetically connected to the waterproof magnetic base 10. The surface of the waterproof magnetic base 10 has an insertion port 11. The outer wall of the magnetic block 9 is adapted to the inner wall of the insertion port 11. There are three sets of waterproof magnetic base 10 and magnetic blocks 9. By inserting the magnetic block 9 into the insertion port 11, it can generate magnetic attraction with the waterproof magnetic base 10, which can quickly fix the stainless steel filter plate 8 inside the housing 1. The side wall of the fixing frame 7 is fixedly connected to the converging ring 12. The converging ring 12 is located on the side of the fixing frame 7 near the impeller 2. The magnetic block 9 is fixedly connected to the outer wall of the fixing frame 7 near the converging ring 12.

[0032] Reference Figures 2-4A titanium dioxide layer 6 is fixedly connected to the surface of the impeller 2. The titanium dioxide layer 6 can also be coated on the inner wall of the housing 1 and the outer side of the guide 4. The titanium dioxide layer 6 is a photocatalytic material. Titanium dioxide has relatively stable chemical properties. Under ultraviolet irradiation, its own structure will not change or be decomposed. Titanium dioxide is a commonly used semiconductor photocatalytic material. It can generate active substances such as hydroxyl radicals with strong oxidizing properties under light irradiation. These active substances can decompose organic pollutants without damaging the titanium dioxide coating itself. When ultraviolet light irradiates the surface of the photocatalytic material, the photocatalytic material will generate active oxygen substances, such as hydroxyl radicals and superoxide anions, which can decompose and degrade organic pollutants attached to the blade and surface, converting them into harmless substances such as carbon dioxide and water, thereby achieving the purpose of self-cleaning. A fixing block 13 is fixedly connected to the outer wall of the converging ring 12. The surface of the fixing block 13 is fixedly connected to ultraviolet light. The ultraviolet lamp 14 is a waterproof lamp. The housing 1 has a sealed power interface, which is connected to the power cord of the ultraviolet lamp. This ensures that the power cord can pass through the interface and enter the housing 1 to supply power to the ultraviolet lamp 14. The power interface uses a corrosion-resistant and high-temperature resistant sealing material, such as fluororubber or silicone rubber, to prevent liquid leakage. The above materials have good elasticity and can form a tight seal at the interface. The sealed power interface design can effectively isolate water flow and prevent liquid from contacting the power cord and the energized parts, thereby preventing short circuits and equipment damage. At the same time, it has good durability and can maintain the sealing performance during long-term use. An adjustment plate 15 is attached to the side wall of the stainless steel filter plate 8. The adjustment plate 15 is made of magnetic material and can adsorb metal impurities in the water. The adjustment plate 15 is located on the outer wall of the stainless steel filter plate 8 away from the converging ring 12. Filter holes 16 are opened through the surface of the adjustment plate 15.

[0033] Reference Figure 2 and Figure 4 A screw hole 18 is provided at the center of the adjusting plate 15. A threaded groove 17 is provided on the inner wall of the stainless steel filter plate 8. A fixing bolt 19 is threadedly connected to the inner wall of the threaded groove 17. The inner wall of the screw hole 18 is threadedly connected to the outer wall of the fixing bolt 19. A moving block 21 is fixedly connected to the side wall of the adjusting plate 15. An annular groove 20 is provided on the side wall of the stainless steel filter plate 8. The outer wall of the moving block 21 is slidably connected to the inner wall of the annular groove 20. By moving the moving block 21 inside the annular groove 20, the alignment of the filter hole 16 with the hole on the surface of the stainless steel filter plate 8 can be switched. The adjusting plate 15 is fixed by using the connection between the fixing bolt 19, the screw hole 18, and the threaded groove 17.

[0034] Working principle: Three sets of magnetic blocks 9 are inserted into the sockets 11 to magnetically attract each set of waterproof magnetic bases 10. After the fixing bracket 7 is installed, the adjusting plate 15 is manually moved. The adjusting plate 15 drives the moving block 21 to slide inside the annular groove 20. After switching the alignment of the filter hole 16 with the hole, the adjusting plate 15 is fixed using the fixing bolt 19. Water is then introduced into the inlet of the housing 1 for flow counting. The converging ring 12 can gather the water source onto the guide 4, and the generated swirling flow forms a scouring force, performing a certain degree of self-cleaning on the impeller 2 surface and the inner wall of the housing 1. The adjusting plate 15 can adsorb metallic impurities present in the water source, and the stainless steel filter plate 8 intercepts impurities, reducing the housing's... Depending on the degree of contamination of impeller 1 and impeller 2, when self-cleaning is required, turn on the ultraviolet lamp 14 to irradiate the inside of housing 1, using light energy to achieve the cleaning process without the need to add chemical agents. At the same time, the photocatalytic material can also inhibit the growth of bacteria and algae, prevent the formation of biological fouling, and facilitate the use of measuring liquids containing organic matter or in environments prone to microbial growth. Photocatalytic self-cleaning can maintain the cleanliness and measurement accuracy of the flow meter for a long time. Finally, insert your hand into the groove of the fixing bolt 19 and apply force outward. After the magnetic block 9 is released from the magnetic attraction of the waterproof magnetic seat 10, it can be removed from housing 1, thereby cleaning the stainless steel filter plate 8 and the regulating plate 15, ensuring the subsequent cleaning effect.

[0035] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
