Description

Technical Field

[0001] This utility model belongs to the technical field of heating system equipment, specifically relating to a double-layer inclined plate anti-mixing temperature control buffer water tank structure for heating systems. Background Technology

[0002] Buffer tanks are the core component of thermal regulation in heating systems. Relying on temperature stratification, they can efficiently couple different types of heat sources such as boilers and heat pumps. By precisely separating fluids with different temperature gradients, they can significantly reduce energy loss and are a key structure for achieving energy-saving operation of the system.

[0003] However, most existing buffer tank designs use the instruction manual attached. Figure 4 The leftmost attached diagram (perforated baffle ①) and the middle attached diagram (double-layer baffle ②) illustrate a scenario where, in practical engineering applications, high-temperature fluid flows downwards from the high-temperature zone, causing an abnormal drop in temperature in the high-temperature zone and an abnormal rise in temperature in the low-temperature zone. This temperature anomaly further interferes with the accuracy of the temperature sensors in both the high and low temperature zones, resulting in temperature values ​​fed back by the sensors that are either lower or higher than the low-temperature threshold required by the actual system.

[0004] The output of heat sources directly connected to high and low temperature zones relies primarily on data from temperature sensors. Incorrect low or high temperature signals can cause the actuator to determine whether the heat source has reached or not reached the target temperature, thus actively increasing or decreasing the output. Ultimately, this leads to increased output from high-temperature heat sources and decreased output from low-temperature heat sources, thereby affecting the adaptability of the end-user load and the comfort of end users.

[0005] Therefore, this utility model provides a double-layer inclined plate anti-mixing temperature control buffer water tank structure for heating systems to solve the problems mentioned in the background art. Utility Model Content

[0006] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a double-layer inclined plate anti-mixing temperature control buffer water tank structure for heating systems, thereby improving the comfort of end users by modifying the water tank structure of the heating system.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A double-layer inclined plate anti-mixing temperature control buffer water tank structure for a heating system includes a vertical cylindrical tank body. An exhaust port is located at the center of the top of the tank body, and a drain port is fixedly located at the center of the bottom of the tank body. An upper water inlet and an upper water outlet are symmetrically arranged on the upper part of the side wall of the tank body, and a lower water inlet and a lower water outlet are symmetrically arranged on the lower part of the side wall of the tank body. A double-layer inclined plate is provided inside the tank body, comprising an upper inclined plate and a lower inclined plate, the edges of which are sealed to the inner wall of the tank body. Multiple upper temperature sensors are installed at the upper water inlet and the upper water outlet, and multiple lower temperature sensors are installed at the lower water inlet and the lower water outlet, respectively.

[0008] Furthermore, the upper and lower inclined plates of the double-layered inclined plates are arranged parallel to each other and inclined in opposite directions.

[0009] Further specified, both the upper and lower inclined plates are located in the middle of the tank body, and the distance between the upper and lower inclined plates is 0.1m.

[0010] Furthermore, a temperature transition chamber is formed between the upper and lower inclined plates.

[0011] Further specified, the upper inclined plate of the double-layer inclined plate has an inclination angle of 30° to 45°, and the edge of the upper inclined plate is higher than the center at the connection between the upper inclined plate and the inner wall of the tank. The lower inclined plate has an inclination angle of 30° to 45°, and the edge of the lower inclined plate is lower than the center at the connection between the lower inclined plate and the inner wall of the tank.

[0012] Further specified, the inclination angle of the double-layer inclined plate is 45°, and the surfaces of the upper and lower inclined plates are provided with guide grooves. The depth of the guide grooves is 2-4 mm, the width is 10-15 mm, the spacing between adjacent guide grooves is 50-80 mm, and the direction of the guide grooves is consistent with the inclination direction of the double-layer inclined plate.

[0013] Further specified, the ratio of the tank diameter to its height is 1:2 to 1:3, the inner wall of the tank is provided with a galvanized anti-corrosion layer with a thickness of 50μm, and a sludge collection trough is provided at the drain outlet at the bottom of the tank.

[0014] Further specified, the double-layer inclined plate is made of stainless steel with a thickness of 3-5mm.

[0015] The beneficial effects of this utility model are: This invention utilizes a double-layered inclined plate system. The two inclined plates are arranged at a certain angle along the inner wall of the buffer tank, with both the upper and lower inclined plates located in the middle of the tank. An independent transition space is formed between the two layers of inclined plates. The purpose of the baffles is to slow down the water flow velocity within the tank, minimizing direct contact between the high-temperature fluid and the low-temperature fluid. Furthermore, the surfaces of the double-layered inclined plates are made of smooth stainless steel with a certain degree of temperature resistance, reducing fluid flow resistance and preventing material wear under long-term high-temperature conditions.

[0016] When the high-temperature fluid enters the tank through the upper inlet, if it shows a downward trend, the upper inclined plate first acts as a physical barrier, guiding the high-temperature fluid to diffuse towards the center of the tank along the inclined direction of the plate, rather than directly impacting the low-temperature area. Even if a small amount of high-temperature fluid breaks through the upper inclined plate, the lower inclined plate will further intercept it, confining it within the transition space between the two inclined plates. During this process, the small amount of high-temperature fluid in the transition space will slowly exchange heat with the surrounding fluid, rather than directly mixing into the low-temperature fluid below, thus effectively preventing abnormal temperature rise in the low-temperature area.

[0021] 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.

[0022] like Figure 4 (See attached image on the far right) and Figure 2 As shown, the present invention discloses a double-layer inclined plate anti-mixing temperature control buffer water tank structure for a heating system, comprising a vertical cylindrical tank body, an exhaust port 8 at the center of the top of the tank body, and a drain port 7 fixedly disposed at the center of the bottom of the tank body; an upper water inlet 1 and an upper water outlet 2 are symmetrically arranged on the upper part of the side wall of the tank body, and a lower water outlet 3 and a lower water inlet 4 are symmetrically arranged on the lower part of the side wall of the tank body; a double-layer inclined plate is provided inside the tank body, the double-layer inclined plate comprising an upper inclined plate and a lower inclined plate, the edges of the upper inclined plate and the lower inclined plate being sealed to the inner wall of the tank body; multiple upper temperature sensors 5 are respectively installed at the upper water inlet 1 and the upper water outlet 2, and multiple lower temperature sensors 6 are respectively installed at the lower water outlet 3 and the lower water inlet 4.

[0023] Specifically, both the upper temperature sensor 5 and the lower temperature sensor 6 are inserted and can directly monitor the temperature of the water about to flow out. Both the upper temperature sensor 5 and the lower temperature sensor 6 are connected to an externally installed thermostat.

[0024] In the practical application of this embodiment, the upper and lower inclined plates of the double-layer inclined plate are arranged parallel and tilted in opposite directions.

[0025] In the practical application of this embodiment, both the upper inclined plate and the lower inclined plate are located in the middle of the tank, and the distance between the upper inclined plate and the lower inclined plate is 0.1m.

[0026] In the practical application of this embodiment, a temperature transition chamber that runs vertically through the upper and lower inclined plates is formed between the upper and lower inclined plates.

[0027] In the practical application of this embodiment, the upper inclined plate of the double-layer inclined plate has an inclination angle of 30° to 45°, and the edge of the upper inclined plate is higher than the center at the connection between the upper inclined plate and the inner wall of the tank. The lower inclined plate has an inclination angle of 30° to 45°, and the edge of the lower inclined plate is lower than the center at the connection between the lower inclined plate and the inner wall of the tank.

[0028] In the practical application of this embodiment, the inclination angle of the double-layer inclined plate is 45°. Guide grooves are formed on the surfaces of both the upper and lower inclined plates. The depth of the guide grooves is 2-4 mm, the width is 10-15 mm, and the spacing between adjacent guide grooves is 50-80 mm. The direction of the guide grooves is consistent with the inclination direction of the double-layer inclined plate. Mechanical simulation shows that with this structural design, when the angle of the double-layer inclined plate is <30°, the water flow velocity along the plate surface is too fast, easily forming eddies; when the angle of the double-layer inclined plate is >60°, the water flow resistance increases, leading to increased energy consumption. The preferred 45° inclination angle extends the spiral flow path of the water flow by 2.5 times. The guide grooves guide the water flow along a preset path, reducing lateral diffusion.

[0029] In the practical application of this embodiment, the ratio of the tank diameter to its height is 1:2 to 1:3, the inner wall of the tank is provided with a galvanized anti-corrosion layer with a thickness of 50μm, and a sludge collection trough is provided at the drain outlet 7 at the bottom of the tank.

[0030] The double-layer inclined plate is made of stainless steel with a thickness of 3-5mm. Specifically, the double-layer inclined plate is made of 304 stainless steel. The sealing connection between the double-layer inclined plate and the inner wall of the tank is made by double-sided argon arc welding with a weld width of ≥8mm and no defects such as porosity or slag inclusion.

[0031] The working principle of this utility model is as follows: This invention utilizes a double-layered inclined plate system. The two inclined plates are arranged at a certain angle along the inner wall of the buffer tank, with both the upper and lower inclined plates located in the middle of the tank. The upper and lower inclined plates are 0.1m apart, forming an independent transition space between the two layers. Furthermore, the surfaces of the double-layered inclined plates are made of smooth stainless steel with a certain degree of temperature resistance, reducing fluid flow resistance and preventing material loss under long-term high-temperature conditions.

[0032] When the high-temperature fluid enters the tank through the upper inlet, if it shows a downward trend, the upper inclined plate first acts as a physical barrier, guiding the high-temperature fluid to diffuse towards the center of the tank along the inclined direction of the plate, rather than directly impacting the low-temperature area. Even if a small amount of high-temperature fluid breaks through the upper inclined plate, the lower inclined plate will further intercept it, confining it within the transition space between the two inclined plates. During this process, the small amount of high-temperature fluid in the transition space will slowly exchange heat with the surrounding fluid, rather than directly mixing into the low-temperature fluid below, thus effectively preventing abnormal temperature rise in the low-temperature area.

[0033] During system startup, the upper temperature sensor 5 and the lower temperature sensor 6 synchronously collect the initial water temperature, and the thermostat calculates the reference temperature difference (e.g., set to 25℃). When the temperature at the upper outlet 2 is lower than the set value (e.g., 55℃), the upper temperature sensor 5 transmits a signal to the thermostat, triggering the following adjustment logic: ① Increase the opening of the upper inlet valve 1 by 10%~15% to increase the flow rate of high-temperature water; ② Decrease the opening of the lower inlet valve 4 by 5%~8% to prolong the residence time of cold water in the tank.

[0034] If the temperature at the upper outlet 2 is higher than the set value, the thermostat will perform the reverse operation: ① reduce the flow rate at the upper inlet 1 and introduce some low-temperature return water at the same time; ② increase the discharge rate at the lower inlet 4 to accelerate the discharge of cold water.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
