Description

Technical Field

[0001] The utility model relates to the technical field of decoupling tanks, in particular to a decoupling tank with a water temperature stratification function. Background Art

[0002] Decoupling tanks, commonly known as mixing tanks, refer to the use of water systems for heating. Due to the hydraulic coupling between the circuits, when the flow of a branch or user changes, the flow of the remaining branches or users and the flow of the boiler will be affected, thus breaking the hydraulic balance of each circulation circuit. Decoupling is performed by using a device that creates an area with almost zero pressure loss, allowing the water pumps to achieve their own circulation without interfering with each other and transferring heat without loss. This device is called a decoupling tank.

[0003] In traditional decoupling tanks with multiple return water temperatures (for example: 50°C return water for domestic hot water heating systems, 40°C return water for floor radiator systems, and 30°C return water for floor heating systems) and multiple heat source systems (for example: gas condensing boilers, biomass boilers, solar energy, gas heat pumps, air source heat pumps, and cogeneration), if the water temperature is not stratified, hot water and cold water will mix in the tank, causing the available water temperature to drop. This will result in higher energy losses, increase the energy consumption of the system, and cause the heat source equipment to not operate at the optimal temperature conditions, reducing the power of the heat source equipment.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] See also Figure 1 The decoupling tank with water temperature stratification function shown in the figure includes a decoupling tank body 1, a plurality of rows of docking tubes 2 are installed on the outside of the decoupling tank body 1, and the number of docking tubes 2 in each row is multiple, a temperature sensor 3 for detecting water temperature is fixedly installed inside the docking tube 2 near the decoupling tank body 1, an exhaust structure 4 is installed on the top of the decoupling tank body 1, and a grille tube 5 for preventing scaling of the inner wall of the decoupling tank body 1 is installed inside the decoupling tank body 1, and the grille tube 5 is made of plastic.

[0022] The working principle of water temperature stratification inside the decoupling tank: the decoupling tank body 1 is divided into different temperature zones according to the optimal design temperature of different heat sources on the primary side and the required temperature of different circulation loops on the secondary side, the corresponding pipes are connected to the flanges of the butt pipe 2, and the water volume of the corresponding area in the decoupling tank body 1 is calculated according to the design flow corresponding to the primary and secondary circulation loops of different temperatures to ensure that the temperature is not mixed. The temperature sensor 3 installed inside the butt pipe 2 can display the temperature of different temperature zones in the decoupling tank body 1. The measured regional temperature can be used to determine whether the flow of different loops is at the optimal working point, guide different loops to adjust the circulating water volume in time, accurately supply water to the corresponding temperature layer, reduce the power consumption of the water pump, improve the operating efficiency of the heat pump and condensing boiler, and at the same time increase the heat storage capacity.

[0023] Embodiment 2

[0024] See also Figure 2 , Figure 4This embodiment further explains the first embodiment. The exhaust structure 4 includes a metal sleeve 401 fixedly installed on the upper end of the decoupling tank body 1 and interconnected with the decoupling tank body 1. A rubber piston 402 that can move up and down is installed inside the metal sleeve 401. The outer wall of the rubber piston 402 is movably attached to the inner wall of the metal sleeve 401. A connecting rod 403 is fixedly embedded at the center of the upper end of the rubber piston 402. The connecting rod 403 can prevent the rubber piston 402 from tilting inside the metal sleeve 401, and the connecting rod 403 runs through the metal sleeve 401. The connection method between the connecting rod 403 and the metal sleeve 401 is a plug-in connection.

[0025] See also Figure 4 A spring 404 is movably sleeved on the outer side of the connecting rod 403, and the spring 404 can drive the rubber piston 402 to move downward, and the two ends of the spring 404 are movably abutted against the metal sleeve 401 and the rubber piston 402 respectively, and two symmetrically distributed exhaust pipes 405 are fixedly installed on the outer side of the metal sleeve 401, and the exhaust pipe 405 and the metal sleeve 401 are connected to each other, and the exhaust pipe 405 can discharge the steam inside the decoupling tank body 1.

[0026] In this embodiment: when the steam pressure inside the decoupling tank body 1 is high, the rubber piston 402 will be driven to move up to the upper side of the exhaust pipe 405. At this time, the over-pressure steam is discharged through the exhaust pipe 405. After the pressure inside the decoupling tank body 1 is released, the rubber piston 402 will move down and reset under the drive of the spring 404, which can avoid accidents caused by excessive pressure inside the decoupling tank body 1.

[0027] Embodiment 3

[0028] See also Figure 3 This embodiment further explains the second embodiment. The grille tube 5 is in sliding contact with the inner wall of the decoupling tank body 1. Two symmetrically distributed bent connecting rods 6 are fixedly embedded in the lower end of the rubber piston 402, and the lower ends of the bent connecting rods 6 are fixedly connected to the grille tube 5. Avoidance grooves 7 are opened on the grille tube 5 corresponding to multiple docking pipes 2. The avoidance grooves 7 can prevent the grille tube 5 from blocking the water inlet and outlet of the docking pipes 2.

[0029] In this embodiment: since the grille tube 5 is connected to the rubber piston 402 through the bent connecting rod 6, the grille tube 5 can reciprocate up and down together with the rubber piston 402. Since the grille tube 5 is in sliding contact with the inner wall of the decoupling tank body 1, the grille tube 5 can prevent sediment from adhering to the inner wall of the decoupling tank body 1 during the up and down reciprocating movement, thereby preventing scale from adhering to the inner wall of the decoupling tank body 1, and can extend the service life of the decoupling tank body 1.
