Description

Technical Field

[0001] This utility model relates to the field of hot water tank technology, specifically an electrically heated hot water tank for CIP pipe cleaning. Background Technology

[0002] During CIP pipeline cleaning, when using conventional cleaning agents, temperature adjustment can be achieved simply by adding hot water; however, when using electrolyzed water for cleaning, undiluted stock solution (i.e., electrolyzed water) must be used directly, and the stock solution must be heated to meet process requirements.

[0003] Chinese patent (authorization announcement number: CN219199481U, authorization announcement date: 2023.06.16) discloses an automatic electric heating hot water tank for CIP pipeline cleaning electrolyzed water, comprising a base, a tank body and a return water pump arranged on the upper part of the base, and the return water pump being connected to the tank body through a return water pipe; a thermometer, a temperature sensor interface, a temperature controller interface, a pressure gauge and a water heater are arranged on the front side of the tank body; a water inlet is arranged on the rear side of the tank body; a manhole is arranged on the left side of the tank body; an electrical control box, an electric heater and a liquid level controller are arranged on the right side of the tank body; a water outlet is arranged on the top of the tank body; and a drain valve is arranged on the bottom of the tank body. The advantages of this utility model are: 1) enabling the heating of electrolyzed water that cannot be diluted with water; 2) possessing automatic temperature control and anti-dry burning functions; 3) being able to be used to heat various water bodies such as electrolyzed acidic water, electrolyzed alkaline water and purified cleaning water, and is not afraid of corrosion.

[0004] The water in the aforementioned hot water tank only transfers heat through natural convection, which easily leads to uneven heating and affects the CIP pipe cleaning effect. Furthermore, after long-term use, impurities easily remain on the inner wall of the tank. There is a lack of a dedicated cleaning mechanism, and manual cleaning requires operation through the manhole, which is inefficient and difficult. Therefore, we propose an electrically heated hot water tank for CIP pipe cleaning. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4This utility model provides a technical solution: an electric heating hot water tank for CIP pipeline cleaning, including a jacketed heating tank 1. The right side of the jacketed heating tank 1 is provided with an inlet 22, a return port 23 and an outlet 24 from top to bottom. An inlet valve 3, a return valve 4 and an outlet valve 5 are respectively installed on the inlet 22, the return port 23 and the outlet 24. The input ends of the inlet valve 3 and the return valve 4 are respectively fixedly connected to the inlet pipe 6 and the return pipe 7. The output end of the outlet valve 5 is fixedly connected to the outlet pipe 8. A stirring assembly is installed inside the jacketed heating tank 1.

[0022] When the electrically heated hot water tank for CIP pipeline cleaning is working, the electrolyzed water enters the jacketed heating tank 1 through the inlet pipe 6 and the inlet valve 3 from the inlet 22. After the stirring component is started, the water in the jacketed heating tank 1 is stirred. The heated water can be output through the outlet 24 and the outlet valve 5 from the outlet pipe 8 for CIP pipeline cleaning. Some of the water can be returned to the jacketed heating tank 1 through the return port 23 and the return valve 4 from the return pipe 7.

[0023] The stirring assembly includes a drive motor 11. A mounting plate 10 is fixedly connected to the top of the jacketed heating tank 1. The drive motor 11 is fixedly installed on the top side of the mounting plate 10. A rotating rod 15 is rotatably installed between the upper and lower sides inside the jacketed heating tank 1. The top end of the rotating rod 15 extends out of the top side of the jacketed heating tank 1 and is fixedly connected to the output shaft end of the drive motor 11. A fixing sleeve 16 is fixedly sleeved in the middle of the rotating rod 15. A spiral stirring blade 17 is fixedly connected to the outer surface of the fixing sleeve 16. A rotating cleaning mechanism is also installed on the top of the jacketed heating tank 1.

[0024] When the stirring assembly is working, after the drive motor 11 starts, its output shaft drives the rotating rod 15 to rotate between the upper and lower sides inside the jacketed heating tank 1. The fixed sleeve 16 in the middle of the rotating rod 15 rotates with it, thereby causing the spiral stirring blades 17 on the outer surface of the fixed sleeve 16 to rotate, thus stirring the water in the jacketed heating tank 1.

[0025] The rotating cleaning mechanism includes a rotating sleeve 18 and a rotating sleeve 19, which are respectively rotatably fitted onto the top and bottom of the rotating rod 15. Connecting plates 21 are fixedly connected to the outer surfaces of both rotating sleeves 18 and 19. A scraper 20 is slidably connected to the inner wall of the jacketed heating tank 1, and the other ends of both sets of connecting plates 21 are fixedly connected to the scraper 20. The top end of the rotating sleeve 18 rotatably extends out from the top side of the jacketed heating tank 1, and two sets of fixing plates 26 are fixedly fitted onto the top of the rotating sleeve 18. Mounting plate 27 is fixedly connected to the right side of mounting plate 26. Threaded groove 28 is provided through mounting plate 27. Threaded post 29 is threaded through threaded groove 28. Limiting rod 32 is fixedly connected to one end of threaded post 29 near rotating sleeve 18. Limiting rod 32 passes through rotating sleeve 18. Limiting groove 31 is provided on the outer surface of rotating rod 15. The other end of limiting rod 32 is inserted into limiting groove 31. Rotating handle 30 is fixedly connected to the other end of threaded post 29. Drainage port 25 is provided at the bottom of jacketed heating tank 1.

[0026] When the rotating cleaning mechanism is working, rotating sleeve 18 and rotating sleeve 29 are respectively fitted on the top and bottom of rotating rod 15. The two are connected to scraper 20 through connecting plate 21. Scraper 20 slides in contact with the inner wall of jacketed heating tank 1. By rotating the rotating handle 30, the threaded column 29 moves in the threaded groove 28 of mounting plate 27, which drives the limiting rod 32 to pass through rotating sleeve 18 and insert into the limiting groove 31 of rotating rod 15. At this time, the rotation of rotating rod 15 can drive rotating sleeve 18 and rotating sleeve 29 to rotate. Through connecting plate 21, scraper 20 is driven to rotate and clean the inner wall of the tank. Impurities generated during cleaning can be discharged from drain port 25.

[0027] A temperature sensor 13 is installed on the rear side of the jacketed heating tank 1, and a control cabinet 14 is provided on the rear side of the jacketed heating tank 1. The temperature sensor 13 monitors the temperature inside the tank in real time and transmits the information to the control cabinet 14. The control cabinet 14 can control the heating and other related components according to the set parameters to achieve precise temperature regulation.

[0028] A safety valve 9 is installed on the top right side of the jacketed heating tank 1. The safety valve 9 automatically opens when the pressure inside the tank exceeds the set value to release the pressure, prevent the tank from being too high and causing a safety accident, and ensure the safe operation of the equipment.

[0029] A manhole 12 is provided on the left side of the jacketed heating tank 1, providing operators with a passage to enter the tank body for inspection, maintenance and other operations, and ensuring that all components of the equipment work normally.

[0030] A ladder 2 is also provided on the left side of the jacketed heating tank 1. The ladder 2 provides operators with a convenient path to go up and down the tank, making it easy for operators to reach different heights of the tank for inspection, maintenance and other work, as well as to manually operate the rotating cleaning mechanism.

[0031] The jacketed heating tank 1 is also equipped with a liquid level sensor on the top side inside, which monitors the liquid level of the water in the tank in real time. When the liquid level reaches or falls below the set value, it can send a signal to coordinate with relevant control components to perform operations such as adding water or stopping heating, so as to prevent dry burning.

[0032] Working principle: When the electric heating hot water tank for CIP pipeline cleaning is working, the electrolyzed water enters the jacketed heating tank 1 through the inlet pipe 6 and the inlet valve 3 from the inlet 22 for heating. Then, after the drive motor 11 starts, its output shaft drives the rotating rod 15 to rotate between the upper and lower sides inside the jacketed heating tank 1. The fixed sleeve 16 in the middle of the rotating rod 15 rotates with it, which in turn causes the spiral stirring blades 17 on the outer surface of the fixed sleeve 16 to rotate, stirring the water in the jacketed heating tank 1. This makes the electrolyzed water inside the jacketed heating tank 1 heated more evenly. The heated water can be output from the outlet pipe 8 through the outlet 24 and the outlet valve 5 for CIP pipeline cleaning. Some water can be returned to the jacketed heating tank 1 through the return port 23 and the return valve 4 from the return pipe 7.

[0033] When excessive scale buildup on the inner wall of the jacketed heating tank 1 necessitates cleaning, rotating sleeve 18 and rotating sleeve 29 are respectively fitted onto the top and bottom of the rotating rod 15. They are connected to the scraper 20 via the connecting plate 21. The scraper 20 slides in contact with the inner wall of the jacketed heating tank 1. By rotating the rotating handle 30, the threaded column 29 moves within the threaded groove 28 of the mounting plate 27, causing the limiting rod 32 to pass through the rotating sleeve 18 and insert into the limiting groove 31 of the rotating rod 15. At this time, the rotating rod 15 driven by the drive motor 11 can drive the rotating sleeve 18 and rotating sleeve 29 to rotate, thereby driving the scraper 20 to rotate via the connecting plate 21 to clean the inner wall of the tank. Impurities generated during cleaning can be discharged from the drain port 25.
