Description

Technical Field

[0001] The present invention belongs to the technical field of energy utilization, mainly relates to the field of heating systems, and particularly relates to a decoupled flow adjustment device and an adjustment method thereof. Background Art

[0002] Currently, during the process of supplying and returning water, a decoupling tank is usually used to balance the hydraulics of the water supply and return system. Using a decoupling tank can reduce the loss of the pump, increase its service life, and reduce energy waste.

[0003] The decoupling tank, commonly known as a mixing water tank, refers to a simple-structured hydraulic adjustment device used in a heating water system to reduce the mutual influence between the primary side and the secondary side circuits, achieve hydraulic coupling between the circuits, and promote hydraulic balance between the circuits. Most decoupling tanks adopt a hollow structure.

[0004] However, an ordinary decoupling tank only performs flow coupling and cannot intelligently increase the pressure and flow rate at the water inlet end. Therefore, it cannot improve user heating, and users at the secondary side of the pipe network end often suffer from insufficient heating. Summary of the Invention

[0005] The problem to be solved by the present invention is to make up for the defects of the above-mentioned prior art and provide a decoupled flow adjustment device that can improve user heating and alleviate insufficient heating of users.

[0006] The technical problem of the present invention can be solved by the following technical solutions:

[0007] A decoupled flow adjustment device includes a box body, a decoupling tank, a water pump, and a controller. The decoupling tank, the water pump, and the controller are all arranged inside the box body. The decoupling tank includes a primary side connected to the main heating pipe network and a secondary side connected to users. The water pump is arranged at the secondary side and is connected to the decoupling tank. The controller includes a water pump control module, and the water pump control module is electrically connected to the water pump and is used to control the operating power of the water pump, so that the secondary side can improve the insufficient heating of secondary-side users without affecting the pressure of the primary-side main pipe network.

[0008] Furthermore, it includes a detection device. The detection device is arranged at one end of the secondary side and is electrically connected to the controller. The detection device can detect the information of the water flow in the secondary side end and feedback the signal to the controller. The controller controls the operating power of the water pump according to the information of the water flow.

[0009] Further, the detection device includes a temperature sensor, which is arranged at one end of the secondary side and electrically connected to the temperature detection module inside the controller. The temperature sensor can detect the water temperature at the secondary side end and transmit the signal to the controller.

[0010] Further, the secondary side includes a secondary water inlet pipe and a secondary water outlet pipe. The temperature sensor includes a water inlet sensor and a water return sensor. The water inlet sensor and the water return sensor are respectively fixedly connected to the secondary water inlet pipe and the secondary water outlet pipe. Moreover, the water inlet sensor and the water return sensor are respectively electrically connected to the controller. The water inlet sensor and the water return sensor respectively detect the water temperature in the secondary water inlet pipe and the secondary water outlet pipe and transmit the signal to the controller.

[0011] Further, the information of the water flow includes the temperature, pressure, and water flow velocity information of the water flow in the secondary side.

[0012] Further, the decoupling tank includes a first baffle and a second baffle. The first water inlet pipe and the second water outlet pipe are respectively located on the left and right sides of the decoupling tank and extend into the interior of the decoupling tank. The first baffle is arranged inside the decoupling tank and close to the end of the first water inlet pipe. The second baffle is arranged inside the decoupling tank and close to the end of the second water outlet pipe. The first baffle and the second baffle respectively block the water flow directions in the first water inlet pipe and the second water outlet pipe.

[0013] Further, the lengths of the first water inlet pipe and the second water outlet pipe extending into the interior of the decoupling tank are both greater than one-half of the width of the decoupling tank.

[0014] Further, the first water inlet pipe includes a first notch, which is arranged at the end of the first water inlet pipe. The second water outlet pipe includes a second notch, which is arranged at the end of the second water outlet pipe.

[0015] Further, the sizes of the first notch and the second notch are one-half of the diameters of the first water inlet pipe and the second water outlet pipe.

[0016] The present invention also provides a method for adjusting the decoupling flow rate by using a decoupling flow rate adjusting device as described above, including the following steps:

[0017] S1: The detection device feeds back the detected water flow information at one end of the secondary side to the controller;

[0018] S2: The controller calculates the difference between the inlet and outlet of the secondary side according to the water flow temperature information fed back by the detection device, and then compares the difference with the preset temperature difference value in the controller to determine whether to send an instruction to the water pump to adjust its operating power.

[0019] S3: When adjustment is needed, the controller sends an instruction to the water pump to adjust its operating power, adjusts the operating power of the water pump, thereby adjusting the flow rate and velocity of the secondary side, and adjusting the heating situation.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] For a decoupled flow rate adjustment device provided by the present invention, its operating principle is as follows: After the return water of the user side, that is, the return water of the secondary side, enters the decoupling tank, it is fully mixed with the relatively hot inlet water from the primary side inside. When the temperature difference between the inlet and return water in the secondary side is relatively low, the water pump connected to the secondary side starts to operate, increasing the pressure and flow rate at the inlet of the end user, and at the same time, increasing the speed of the water supply cycle, so that the heat released per unit time increases, thereby achieving the purpose of improving user heating. The decoupled flow rate adjustment device provided by the present invention can improve the situation of insufficient heating of the secondary side users without affecting the pressure of other user ends in the primary side main pipe network during the operation process.

[0022] A controller is provided in the present invention, which can intelligently calculate the information detected by the temperature sensor and use it as the basis for controlling the water pump, realizing the intelligence of the overall decoupled flow rate adjustment device. In addition, a wireless transmission unit is also provided in the controller, which can transmit the signal detected by the temperature sensor to an external server, etc., to realize data interaction with the outside world.

[0023] The decoupling tank used in the decoupled flow rate adjustment device provided by the present invention includes a baffle and a notch. The structural and positional design of the baffle and the notch can make the most efficient use of the mixing amount of the hot water entering the decoupling tank, thereby increasing the amount of hot water entering the user end and improving the heat exchange efficiency.

It should also be noted that unless otherwise clearly specified and defined, if terms such as "set", "connected", "connected" are used, they should be understood in a broad sense.

For those skilled in the art, the specific meanings of the above terms in the present invention can be specifically understood.

[0039] The present invention provides a decoupling flow adjustment device, which includes a box body 1, a decoupling tank 2, a water pump 3 and a controller 5. The decoupling tank 2, the water pump 3 and the controller 5 are all arranged and fixed inside the box body 1. The decoupling tank 2 is arranged at the bottom of the box body 1 and includes a primary side 21 and a secondary side 22. The water pump 3 is arranged at the secondary side 22 and is connected to the decoupling tank 2. The controller 5 is electrically connected to the water pump 3 to control the operating power of the water pump 3, so as to improve the heating shortage of the end-users of the pipe network, that is, at the secondary side 22, without affecting the pressure of the primary main pipe network.

[0040] The box body 1 includes a box bottom 11 and a box cover 12. The decoupling tank 2, the water pump 3 and the controller 5 are all arranged and fixed inside the box bottom 11. One end of the box cover 12 is pivotally connected to the box bottom 11, and the other end can be fixedly connected by a buckle, so as to protect the components inside the box bottom 11 and avoid damage.

[0041] The decoupling tank 2 is arranged and fixed at the bottom of the box bottom 11 and includes a primary side 21 and a secondary side 22. The primary side 21 is connected to the heat supply main pipe network and is used to provide heating heat source for the secondary side users at the end of the pipe network. The primary side 21 includes a primary inlet pipe 211 and a primary outlet pipe 212. The water from the heat supply main pipe network enters from the primary inlet pipe 211 and then flows out from the primary outlet pipe 212 to complete the circulation of the primary side. The secondary side 22 is connected to the end of the pipe network, that is, the household heating facilities of the users, and is used to provide heating for the user's family. The secondary side 22 includes a secondary inlet pipe 221 and a secondary outlet pipe 222. The water at the user end enters from the secondary inlet pipe 221 and then flows out from the secondary outlet pipe 222 to complete the circulation of the secondary side.

[0042] The controller 5 includes a water pump control module. The water pump 3 is arranged on the secondary inlet pipe 221 and is electrically connected to the water pump control module. The controller 5 can control the operating power of the water pump 3, thereby controlling the flow rate and flow of the water in the secondary side 22, increasing the heat released per unit time, and improving the heating shortage of the end-users of the pipe network, that is, at the secondary side 22. At the same time, the water pump 3 is arranged at the secondary side 22 and will not affect the pressure of other user ends of the primary main pipe network.

[0043] The above is an embodiment in the technical solution. In this embodiment, if it is necessary to adjust the heating heat of the secondary side 22, the controller 5 can be manually operated to control the operating power of the water pump 3 through the water pump control module, thereby increasing the flow rate and flow of the water entering the secondary inlet pipe 221, increasing the heat released by the heating system at the user end per unit time, and improving the heating situation of the secondary side users.

[0044] Preferably, the controller 5 includes a temperature detection module. Temperature sensors 4 electrically connected to the temperature detection module of the controller 5 are respectively provided at the secondary water inlet pipe 221 and the secondary water outlet pipe 222. The temperature sensors 4 include a water inlet sensor 41 and a water return sensor 42. The water inlet sensor 41 is threadedly connected to the secondary water inlet pipe 221, and the water return sensor 42 is threadedly connected to the secondary water outlet pipe 222. The two sensors can detect the water temperature in the pipes and feed back signals to the controller 5. Preferably, the controller 5 includes a calculation and comparison module. The calculation and comparison module is connected to the temperature detection module and the water pump control module, and a preset temperature difference preset value is set in the calculation and comparison module.

[0045] The above preferred solution of adding the temperature detection module and the calculation and comparison module is another embodiment of the present invention. In this embodiment, the water inlet sensor 41 and the water return sensor 42 transmit the water temperatures detected in the secondary water inlet pipe 221 and the secondary water outlet pipe 222 respectively to the temperature detection module. The data of the temperature detection module is transmitted to the calculation and comparison module. The controller 5 automatically calculates the actual water temperature difference between the two by using the calculation and comparison module and compares it with the preset temperature difference preset value in the calculation and comparison module. When the water temperature difference between the secondary water inlet pipe 221 and the secondary water outlet pipe 222 is large, it indicates that the heating effect of the secondary-side users is not ideal. Then the controller 5 sends an instruction to adjust the operating power of the water pump 3 to the water pump control module, controls the operating power of the water pump 3, increases the flow rate and velocity of the water entering the secondary water inlet pipe 221, so as to increase the heat released by the heating system at the user end per unit time and improve the heating shortage of the secondary-side users.

[0046] Preferably, a wireless transmission unit is provided in the controller 5 for data interaction with the outside world. Specifically, the wireless transmission unit includes a Bluetooth module and a 4G module. Among them, the Bluetooth module can be connected to a mobile terminal, such as a mobile phone, at a short distance, enabling on-site staff to debug and configure parameters for the device of the present invention; the 4G module can be wirelessly connected to a server remotely.

[0047] In this embodiment, the temperature sensor 4 transmits the detected information to the controller 5, and the controller 5 then conducts data interaction with the outside world through the wireless transmission unit, transmits the detected information to the server. At the same time, on-site staff can also control the controller 5 through the wireless transmission unit, and then control the entire decoupling flow adjustment device, so as to adjust the heating situation of the secondary-side users.

[0048] The inside of the decoupling tank 2 includes a first baffle 23 and a second baffle 24. The first water inlet pipe 211 and the second water outlet pipe 222 are respectively located on the left and right sides of the decoupling tank 2 and extend into the inside of the decoupling tank 2. Moreover, the lengths a of both extending into the inside of the decoupling tank 2 are greater than one-half of the width b of the decoupling tank 2, that is, a﹥(b / 2). At this time, the water entering from the first water inlet pipe 211 and the second water outlet pipe 222 can be fully mixed and undergo a full decoupling effect inside the decoupling tank 2. Preferably, the length a is equal to two-thirds of the width b, that is, a=(2 / 3)b. At this time, the water entering from the first water inlet pipe 211 and the second water outlet pipe 222 can be maximally and fully mixed inside the decoupling tank 2. And the hot water entering from the first water inlet pipe 211 can be preferably located in the upper layer as much as possible, so that the heat of the water entering the second water inlet pipe 221 can be increased as much as possible. The first baffle 23 is arranged inside the decoupling tank 2 and close to the end 211A of the first water inlet pipe 211, and the second baffle 24 is arranged inside the decoupling tank 2 and close to the end 222A of the second water outlet pipe 222.

[0049] The first water inlet pipe 211 includes a first notch 2111. The first notch 2111 is arranged on the end 211A of the first water inlet pipe 211 and forms a semi-closed channel with the first baffle 23. The water flowing through the first water inlet pipe 211 is blocked by the first baffle 23 at the end 211A of the first water inlet pipe 211 and flows into the inside of the decoupling tank 2 through the first notch 2111. The second water outlet pipe 222 includes a second notch 2221. The second notch 2221 is arranged on the end 222A of the second water outlet pipe 222 and forms a semi-closed channel with the second baffle 24. The water flowing through the second water outlet pipe 222 is blocked by the second baffle 24 at the end 222A of the second water outlet pipe 222 and flows into the inside of the decoupling tank 2 through the notch 2221.

[0050] It should be noted that there are certain requirements for the sizes of the first notch 2111 and the second notch 2221. If the notches are too small, the flow rates of the water flowing into the inside of the decoupling tank 2 from the first water inlet pipe 211 and the second water outlet pipe 222 will be affected. If the notches are too large, the flow velocity of the water flowing into the inside of the decoupling tank 2 will be insufficient, thereby resulting in a decline in the water mixing effect. Through multiple experiments on the notch sizes, preferably, the sizes of the first notch 2111 and the second notch 2221 are one-half of the diameters of the first water inlet pipe 211 and the second water outlet pipe 222.

[0051] The working principle of the present invention will be further described below.

[0052] In the present invention, the primary side 21 is connected to the heating main pipeline, and the secondary side 22 is connected to the household heating facilities of users. The water circulating in both is mixed in the decoupling tank 2. Specifically, the hot water provided by the heating main pipeline enters the decoupling tank 2 through the primary inlet pipe 211 and flows out from the primary outlet pipe 212. The water at the user end enters from the secondary inlet pipe 221 and then flows out from the secondary outlet pipe 222. The water temperature sensors 41 and 42 detect the water temperatures in the secondary inlet pipe 221 and the secondary outlet pipe 222 and transmit them to the controller 5. The controller 5 can automatically calculate the temperature difference between the two. When the temperature difference between the water temperatures in the secondary inlet pipe 221 and the secondary outlet pipe 222 is large, the controller 5 controls the operating power of the water pump 3 to increase the flow rate and velocity of the water entering the secondary inlet pipe 221, so as to increase the heat released by the heating system at the user end per unit time and improve the insufficient heating condition of the secondary side users.

[0053] Among them, the temperature difference between the water temperatures in the secondary inlet pipe 221 and the secondary outlet pipe 222 can be set to any value within 5 - 30 °C. When setting the value, it can be set closely through the Bluetooth module or remotely through the 4G module to the server.

[0054] The water pump 3 in the present invention has three gears corresponding to different operating powers. The controller 5 adjusts the operating power of the water pump 3 according to the values detected by the temperature sensor 4. For example, if the set water temperature difference is 30 °C, when the temperature difference detected by the water inlet sensor 41 and the water return sensor 42 is greater than 30 °C, the controller 5 controls the water pump 3 to increase one gear to increase the power of the water pump 3, thereby increasing the flow rate and velocity of the water entering the secondary inlet pipe 221 to achieve the purpose of adjusting the flow rate.

[0055] In the present invention, the structural design of the baffle and notch in the decoupling tank 2 can make the mixing amount of the hot water entering the decoupling tank 2 be utilized with the highest efficiency. Specifically, the hot water with a higher water temperature entering from the primary inlet pipe 211, due to the end 211A of the primary inlet pipe 211 being at a high position of (2 / 3)b and the structural design of the primary baffle 23 and the primary notch 2111, the entering hot water will not directly rush into the pipeline of the secondary inlet pipe 221, but the water flow is fully rotated and mixed in the decoupling tank 2 and then flows out from the secondary inlet pipe 221. Similarly, the relatively cold return water entering from the secondary outlet pipe 222, due to the end 222A of the secondary outlet pipe 222 being at a low position of (2 / 3)b and the structural design of the secondary baffle 24 and the secondary notch 2221, the entering return water will not directly rush into the pipeline of the primary outlet pipe 212, but the water flow is fully rotated and mixed in the decoupling tank 2 and then flows out from the primary outlet pipe 212. The purpose of this design is to make the mixing amount of the hot water entering the decoupling tank be utilized with the highest efficiency, thereby increasing the amount of hot water entering the user end and improving the heat exchange efficiency.

[0056] The present invention also provides a method for decoupling flow rate adjustment by using a decoupling flow rate adjustment device as described above, comprising the following steps:

[0057] S1: The detection device feeds back the water flow information detected at one end of the secondary side 22 to the controller 5.

[0058] Preferably, the detection device includes a water inlet sensor 41 and a water return sensor 42, and the water inlet sensor 41 and the water return sensor 42 feed back the detected water flow temperature information of the secondary water inlet pipe 221 and the secondary water outlet pipe 222 to the controller 5.

[0059] S2: The controller 5 calculates the difference between the water inlet end and the water outlet end of the secondary side 22 according to the water flow temperature information fed back by the detection device, and then compares the difference with a preset temperature difference value preset in the controller 5 to determine whether to send an instruction to adjust its operating power to the water pump 3.

[0060] Preferably, the preset temperature difference value in the controller 5 is any value between the minimum value e and the maximum value f. Preferably, before using the decoupling flow rate adjustment device, the preset temperature difference value can be set on the controller 5 through the wireless transmission unit for comparison with the actual detection data. Preferably, e = 5°C and f = 30°C. Let the water temperature difference between the water inlet end and the water outlet end of the secondary side 22 be k. If k is greater than the preset temperature difference value, the controller 5 sends an instruction to increase the operating power of the water pump 3; if k is less than the preset temperature difference value, the controller 5 sends an instruction to decrease the operating power of the water pump 3.

[0061] S3: When adjustment is required, the controller 5 sends an instruction to adjust its operating power to the water pump 3, adjusts the operating power of the water pump 3, thereby adjusting the flow rate and flow velocity of the secondary side 22, and adjusting the heating situation.

[0062] As an alternative means, the user can also directly adjust the controller 5 according to the actual situation through the wireless transmission unit, and then adjust the operating power of the water pump 3.

[0063] The specific embodiments of the present invention have been described in detail above. For those skilled in the art of this technology, without departing from the principle of the present invention, several modifications and improvements can still be made to the present invention, and these modifications and improvements also fall within the protection scope of the claims of the present invention.
