Description

Technical Field

[0001] This utility model relates to the field of water return mixing tank technology, and in particular to a multi-energy water supply and return mixing balance tank. Background Technology

[0002] Multi-energy supply and return water mixing balance tank is a device used for fluid transportation and storage. It is mainly used to achieve the mixing and balance of fluids from different sources and multiple energy sources in heating, cooling, air conditioning and industrial cooling systems. The tank achieves uniform temperature and flow balance by stirring and mixing water of different temperatures and properties, ensuring the stability and consistency of the outlet fluid. However, most existing multi-energy supply and return water mixing balance tanks still have problems that need to be solved.

[0003] In most existing technologies, the agitators of multi-energy supply and return water mixing balance tanks are fixed to the rotating shaft by welding, which makes them difficult to disassemble. The agitators are prone to accumulating dirt and sediment during long-term operation. The difficulty in disassembly complicates the cleaning process, which may reduce the efficiency of maintenance work, affect product quality, increase downtime, and increase operating costs. Therefore, it is urgent to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-energy supply and return water mixing and balancing tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-energy supply and return water mixing and balancing tank includes a tank body. A drive shaft is installed inside the tank body, and a rotating shaft is installed at the bottom end of the drive shaft. A stirrer is fixedly connected to the outer wall of the rotating shaft. Two positioning pins are fixedly connected to one side of the top end of the rotating shaft. Two positioning grooves adapted to the positioning pins are formed at the bottom end of the drive shaft. Two limiting grooves are formed at the top end of the rotating shaft. Each of the two limiting grooves has a limiting rod installed. The limiting rods are slidably connected to the rotating shaft. A common connecting plate is fixedly connected to the same side of the two limiting rods. A U-shaped seat is fixedly connected to the connecting plate on the side away from the limiting rods. A roller is rotatably connected to the U-shaped seat. Two pins are fixedly connected to the connecting plate on the side away from the U-shaped seat. Two slots adapted to the pins are formed on the drive shaft. A conical ring is installed inside the tank body, and a circular ring is fixedly connected to the bottom of the conical ring. Because a technical means is adopted that allows the pins to insert into the slots during the process of placing the drive shaft and rotating shaft into the tank body, During the insertion of the rotating shaft, the roller moves along the inner wall of the conical ring. When the roller reaches the inner wall of the ring, the pin is fully inserted into the slot, thus restricting the position between the drive shaft and the rotating shaft, fixing the rotating shaft, and thus installing the agitator. For disassembly, the drive shaft and rotating shaft are removed, and the pin is removed from the slot to separate them, allowing the rotating shaft and agitator to be removed for cleaning. This effectively solves the problems mentioned in the background technology, where the agitator in most existing multi-energy supply and return water mixing balance tanks is generally fixed to the rotating shaft by welding, making disassembly and assembly difficult. Long-term operation of the agitator easily leads to the accumulation of dirt and sediment, and the difficulty in disassembly complicates cleaning, potentially reducing maintenance efficiency, affecting product quality, increasing downtime, and increasing operating costs. This technology effectively reduces the difficulty of disassembling and assembling the agitator, significantly improves maintenance efficiency, greatly reduces equipment downtime, and reduces overall operating costs.

[0006] As a further embodiment of this utility model, both of the limiting rods are fixedly connected to a round block on the side away from the connecting plate.

[0007] As a further embodiment of this utility model, a feed pipe is fixedly connected to the top of the tank, a cover plate is fastened to the top of the feed pipe by screws, a fixed seat is fixedly connected to the top of the cover plate, a motor is fixedly connected to the top of the fixed seat, and the output end of the motor is connected to the top of the drive shaft through a coupling.

[0008] As a further embodiment of this utility model, three water inlet pipes are fixedly connected to one side of the tank.

[0009] As a further embodiment of this utility model, a valve is fixedly connected to the bottom outlet of the tank, and a water outlet pipe is fixedly connected to the output end of the valve.

[0010] As a further embodiment of this utility model, a temperature sensor is fixedly connected to the outer wall of the tank, and the detection end of the temperature sensor is located inside the tank.

[0011] As a further embodiment of this utility model, the inner wall of the tank is fixedly connected with four fixing rods, and all four fixing rods are fixedly connected to the outer wall of the ring.

[0012] The beneficial effects of this utility model are as follows: By employing a technique that allows the pin to be inserted into the slot during the insertion of the drive shaft and rotating shaft into the tank, the roller moves along the inner wall of the conical ring during shaft insertion. When the roller reaches the inner wall of the ring, the pin is fully inserted into the slot, thus restricting the position between the drive shaft and rotating shaft, securing the rotating shaft, and allowing the agitator to be installed. Disassembly involves removing the drive shaft and rotating shaft, and removing the pin from the slot to separate them, allowing for easy removal and cleaning of the rotating shaft and agitator. This effectively solves the problems mentioned in the background art, where most existing multi-energy supply and return water mixing balance tanks have agitators that are typically fixed to the rotating shaft by welding, making disassembly and assembly difficult. Long-term operation of the agitator easily leads to the accumulation of dirt and sediment, complicating cleaning work and potentially reducing maintenance efficiency, affecting product quality, increasing downtime, and increasing operating costs. This technique effectively reduces the difficulty of disassembling and assembling the agitator, significantly improves maintenance efficiency, greatly reduces equipment downtime, and reduces overall operating costs.

[0015] 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.

[0016] Reference Figure 1-5 A multi-energy supply and return water mixing balance tank includes a tank body 1. A drive shaft 2 is installed inside the tank body 1. A rotating shaft 3 is installed at the bottom end of the drive shaft 2. An agitator 301 is fixedly connected to the outer wall of the rotating shaft 3. Two positioning pins 4 are fixedly connected to one side of the top end of the rotating shaft 3. Two positioning grooves 5 are formed at the bottom end of the drive shaft 2, which are adapted to the positioning pins 4. Two limiting grooves 6 are formed at the top end of the rotating shaft 3. Each limiting groove 6 is provided with a limiting rod 7. The limiting rod 7 is slidably connected to the rotating shaft 3. The two limiting rods 7 are simultaneously... A connecting plate 8 is fixedly connected to one side. A U-shaped seat 9 is fixedly connected to the connecting plate 8 on the side away from the limiting rod 7. A roller 10 is rotatably connected to the U-shaped seat 9. Two pins 11 are fixedly connected to the connecting plate 8 on the side away from the U-shaped seat 9. Two slots 12 adapted to the pins 11 are opened on the drive shaft 2. A conical ring 13 is provided inside the tank body 1. A circular ring 14 is fixedly connected to the bottom of the conical ring 13. Due to the design, the pins can be inserted into the slots during the process of placing the drive shaft and rotating shaft into the tank body. This technology utilizes advanced techniques to ensure that during the insertion of the rotating shaft, the roller moves along the inner wall of the conical ring. When the roller reaches the inner wall of the ring, the pin fully inserts into the slot, thus restricting the position between the drive shaft and the rotating shaft, securing the rotating shaft, and allowing the agitator to be installed. Disassembly involves removing the drive shaft and rotating shaft, and removing the pin from the slot to separate them, allowing for easy removal and cleaning of the rotating shaft and agitator. This effectively solves the problems mentioned in the background section, where most existing multi-energy supply and return water mixing balance tanks have agitators that are typically fixed to the rotating shaft by welding, making disassembly and assembly difficult. Long-term operation of the agitator can lead to the accumulation of dirt and sediment, complicating cleaning and potentially reducing maintenance efficiency, affecting product quality, increasing downtime, and raising operating costs. This technology effectively reduces the difficulty of disassembling and assembling the agitator, significantly improves maintenance efficiency, greatly reduces equipment downtime, and lowers overall operating costs.

[0017] In this embodiment, two limiting rods 7 are fixedly connected to round blocks 15 on the side away from the connecting plate 8. The round blocks 15 are used to prevent the limiting rods 7 from detaching from the rotating shaft 3.

[0018] In this embodiment, a feed pipe 16 is fixedly connected to the top of the tank 1, and a cover plate 17 is fastened to the top of the feed pipe 16 by screws. A fixing seat 18 is fixedly connected to the top of the cover plate 17, and a motor 19 is fixedly connected to the top of the fixing seat 18. The output end of the motor 19 is connected to the top of the drive shaft 2 through a coupling.

[0019] In this embodiment, three water inlet pipes 20 are fixedly connected to one side of the tank body 1, and water from multiple sources is injected into the tank body 1 through the water inlet pipes 20.

[0020] In this embodiment, a valve 21 is fixedly connected to the bottom outlet of the tank 1, and a water outlet pipe 22 is fixedly connected to the output end of the valve 21. The mixed water is discharged through the valve 21 and the water outlet pipe 22.

[0021] In this embodiment, a temperature sensor 23 is fixedly connected to the outer wall of the tank 1. The detection end of the temperature sensor 23 is located inside the tank 1. The temperature sensor 23 detects the temperature of the mixed water in the tank 1. The temperature sensor 23 is connected to the PLC controller of the peripheral device. The data detected by the temperature sensor 23 is processed and displayed on the display screen of the PLC controller.

[0022] In this embodiment, four fixing rods 24 are fixedly connected to the inner wall of the tank 1, and all four fixing rods 24 are fixedly connected to the outer wall of the ring 14.

[0023] Working principle: During use, fluids from multiple energy sources, such as hot water, cold water, and steam, are injected into tank 1 through multiple inlet pipes 20. An external power supply is used. An external PLC controller starts motor 19 and temperature sensor 23. Temperature sensor 23 detects the stability of the mixed water in tank 1. The rotation of motor 19 drives the coupling, which in turn drives drive shaft 2. Drive shaft 2 drives rotating shaft 3, which in turn drives agitator 301 to accelerate the mixing of various water sources. After mixing is complete... Open valve 21 to discharge the mixed water through outlet pipe 22. During assembly, insert positioning pin 4 into positioning groove 5 to make drive shaft 2 and rotating shaft 3 fit together. Then, put agitator 301, rotating shaft 3, and drive shaft 2 into tank 1 through feed pipe 16. During this process, roller 10 will contact the inner wall of conical ring 13. If roller 10 continues to descend, it will move along the inner wall of conical ring 13, which will move conical ring 13 towards the circular block 15. Roller 10 will drive U-shaped seat 9 to move, and U-shaped seat 9 will... The connecting plate 8 moves, causing the limiting rod 7 to move along the limiting groove 6, ensuring stability during movement. The movement of the connecting plate 8 also moves the pin 11. When the roller 10 reaches the inner wall of the ring 14, the pin 11 is fully inserted into the slot 12, thus limiting the position between the drive shaft 2 and the rotating shaft 3, completing the installation of the rotating shaft 3. As the drive shaft 2 and rotating shaft 3 rotate, the roller 10 moves in a circular motion along the inner wall of the ring 14, preventing the pin 11 from dislodging from the slot 12, ensuring the stability of the drive shaft 2 and rotating shaft 3. When the position between the two shafts is stable and the stirrer 301 needs to be removed for cleaning, remove the drive shaft 2 and the rotating shaft 3 from the tank 1. Manually move the roller 10 away from the rotating shaft 3 to remove the pin 11 from the slot 12, thus removing the restriction on the position between the drive shaft 2 and the rotating shaft 3. This will separate the drive shaft 2 from the positioning pin 4, and also separate the rotating shaft 3 from the drive shaft 2. The rotating shaft 3 and the stirrer 301 can then be removed. The stirrer 301 can then be thoroughly cleaned to remove dirt, sediment, etc., before reassembly.

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.
