Description

Technical Field

[0001] This utility model relates to the field of closed-loop circulation system technology, specifically a high-level tank for a closed-loop circulation system. Background Technology

[0002] The elevated tank maintains stable system pressure through the static pressure generated by the liquid level, preventing equipment damage or malfunctions caused by pressure fluctuations. In a closed-loop system, it serves as a pressure stabilizing point, ensuring the circulating medium flows at a constant pressure. The elevated tank must be installed at the highest point of the system to ensure static pressure covers the entire circulation loop. Its height needs to be calculated and determined based on the system operating pressure, medium density, and pipeline resistance.

[0003] In some existing elevated tanks, the internal components impact the water flow during use. As the water flows from a high point to a low point inside the tank, a significant impact force is generated. This impact force can cause vibrations in the inner wall of the elevated tank, making the surface of the tank susceptible to deformation due to the impact force and vibrations caused by the water flow. This reduces the service life of the elevated tank. Utility Model Content

[0004] The purpose of this invention is to provide a high-level tank for a closed-loop circulation system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a closed-loop circulation system high-level tank, comprising a tank body and an inlet pipe connected above its surface, and further comprising:

[0006] A connecting shell connected to the bottom of the tank guides water through a conical shape. The bottom of the connecting shell is connected to a water outlet pipe. A guide plate with a matching shape is installed above the inner cavity of the tank to reduce the impact force of the water flow.

[0007] A flow-dividing mechanism, located in the middle of the tank's internal cavity, disperses and divides the water flow through different orifices. Inside the connecting shell, a blocking mechanism is installed, whose shape allows the water flow to be sprayed radially.

[0008] Preferably, the diversion mechanism includes a baffle plate fixed to the inner wall of the tank, the surface of the baffle plate is provided with diversion holes, and a flow-blocking frame is provided below the baffle plate.

[0009] Preferably, the blocking mechanism includes a support rod fixed to the inner wall of the connecting shell, a fixed shell fixedly connected to the top of the support rod, and a blocking ring fixedly connected to the inner wall of the connecting shell.

[0010] Preferably, the number of diversion holes is several, and the diameter near the edge of the baffle plate is smaller than the diameter near the center.

[0011] Preferably, the top of the fixing shell is designed with an arc shape, and the position of the fixing shell corresponds to that of the water outlet pipe.

[0012] Preferably, the guide plate has a spiral structure design and is used in conjunction with the water inlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the use of a guide plate, slows down the water flow rate, thereby reducing the impact force of the water and minimizing the possibility of the water flow damaging the tank under the impact force. Furthermore, with the assistance of a diversion mechanism, the water flow is further segmented, disrupting large-scale eddies and slowing down the water flow rate, thus reducing water flow oscillations and making the high-level tank more stable during use. In addition, the combination of the connecting shell and the blocking mechanism reduces the occurrence of eddies, minimizing the impact of the water flow on the high-level tank. This solves the problem of existing high-level tanks being prone to deformation and vibration during use, which affects their service life. Attached Figure Description

[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 1-4As shown, a closed-loop circulation system high-level tank includes a tank body 1. A water inlet pipe 2 connects to the upper surface of the tank body 1, allowing water to enter the tank body 1. A connecting shell 3 connects to the bottom of the tank body 1, and a water outlet pipe 5 connects to the bottom of the connecting shell 3. When the pressure inside the tank body 1 is low, water can be discharged from the diversion mechanism 4 through the connecting shell 3, thus maintaining the pressure of the water components in the circulation system and making the water pressure more stable. The inner cavity of the connecting shell 3 has a conical structure design, which guides the water through the shape of the connecting shell 3, thereby reducing the amount of water entering the connecting shell. The internal flow of the shell 3 forms a vortex, which makes the high-level tank more stable during use and avoids affecting the service life of the high-level tank under the action of water vortex. A guide plate 7 is installed on the upper part of the inner cavity of the tank body 1. The guide plate 7 has a spiral structure design and works with the water inlet pipe 2. Under this action, the water flow can be guided by the shape of the guide plate 7, so that the water can be separated from the air. It can also make the water flow along the shape of the guide plate 7 after entering the water inlet pipe 2, thereby reducing the impact force of the water flow on the corrosion of the tank body 1 and reducing the oscillation of the water surface after the water flow enters the tank body 1.

[0022] A diversion mechanism 4 is provided in the middle part of the inner cavity of the tank body 1. The diversion mechanism 4 can divert the water flow entering the tank body 1, so that the water flow can be more uniform. This reduces the situation where the water flow is not evenly dispersed and the water surface oscillation amplitude is large. It can also slow down the flow speed and flow direction of the water, thereby further reducing the impact force of the water flow and effectively improving the service life of the high-level tank. A blocking mechanism 6 is installed inside the connecting shell 3. The blocking mechanism 6 can block the water above, thereby further buffering the impact force of the water flow. This reduces the surface deformation of the connecting shell 3 due to the large impact force of the water flow after long-term use, and effectively improves the service life of the connecting shell 3.

[0023] The diversion mechanism 4 includes a baffle plate 41 fixed to the inner wall of the tank 1. The surface of the baffle plate 41 is provided with diversion holes 42. There are several diversion holes 42, and the diameter near the edge of the baffle plate 41 is smaller than the diameter near the middle. By matching the number and shape of the diversion holes 42, the water flow can be evenly dispersed to match the speed and distribution of the water flow. A flow-blocking frame 43 is provided below the baffle plate 41. The surface of the flow-blocking frame 43 is fixedly connected to the inner wall of the tank 1. Under this action, the flow-blocking frame 43 can further divide the water flow into multiple thin streams, thereby destroying large-scale eddies and enabling the water flow to tend to a laminar flow state.

[0024] The blocking mechanism 6 includes a support rod 61 fixed to the inner wall of the connecting shell 3. A fixed shell 62 is fixedly connected to the top of the support rod 61. The top of the fixed shell 62 has an arc-shaped structure design. The position of the fixed shell 62 corresponds to that of the water outlet pipe 5. Under this action, the water flow can be blocked by the shape and position of the fixed shell 62, thereby further reducing the occurrence of eddies in the water flow. The arc shape can also disperse the impact force of the water flow. At this time, the water flow can be symmetrically and radially split after impacting the surface of the fixed shell 62, and the turbulent kinetic energy decays faster. A blocking ring 63 is fixedly connected to the inner wall of the connecting shell 3. There are several blocking rings 63. Under this action, after the water flow passes through the guide shape of the connecting shell 3, the blocking rings 63 can further block the water flow, thereby making it less likely for the water flow to form a vortex, thereby reducing the occurrence of eddies in the water flow.

[0025] It is worth noting that the technical features such as tank 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0026] Working principle: First, after water enters the tank 1 through the inlet pipe 2, the shape and position of the guide plate 7 effectively reduce the speed of the water flow, thereby mitigating the impact of the water flow. With the cooperation of the baffle plate 41 and the diversion hole 42, the water can be diverted through different orifice diameters, thereby disrupting large-scale eddies. With the cooperation of the flow-blocking frame 43, the water flow is further divided. After being divided, the water flows to the outlet pipe 5 after being guided by the connecting shell 3. Some water is also dispersed in a jet-like manner by being guided by the fixed shell 62, which further reduces the occurrence of eddies. This reduces the impact force of water on the tank 1 and the inlet pipe 2, and also reduces the stress, thereby improving the service life of the high-level tank.
