Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tank water level control, in particular to a concentrated water tank water level control system and a water storage tank. BACKGROUND

[0002] In the treatment and application of the Yellow River water, the concentrated water of the Yellow River is the treated water isolated outside the reverse osmosis membrane, and its concentration is between that of raw water and pure water. When used, a part of it is usually buffered in a water storage tank. A water level control mechanism needs to be provided in the water storage tank to observe the water level in the water storage tank, and the water inflow and outflow of the water storage tank are controlled according to the water level. Common water level detection mechanisms include a floating ball, such as the water level control structure disclosed in Chinese patent CN216748547U, which uses a float to determine the water level in the tank. When the water level in the tank reaches a low water level, the water outlet pipe is forcibly closed. However, this mechanism cannot determine the change in water level during water inflow, i.e., it cannot determine whether the water level in the tank reaches the target water level during water inflow. If the water level in the tank is not known during water inflow, water overflow may occur, which not only wastes water resources, but also may affect the service life of the tank or the safety of its movement due to excessive water storage in the tank.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. In addition, "in an embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment.

In addition, the terms "comprises", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that the object or terminal device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such object or terminal device. Without more limitations, the element defined by the statement "comprising a" does not exclude the presence of additional identical elements in the object or terminal device including the element.

[0024] In the Yellow River water treatment and application, the Yellow River concentrated water is the treated water isolated outside the reverse osmosis membrane, and its concentration is between raw water and pure water. When used, a part of it is usually cached in a water storage tank, and a water level control mechanism needs to be provided in the water storage tank to observe the water level in the water storage tank, and the water inflow and outflow of the water storage tank are controlled according to the water level. Common water level detection mechanisms include floating balls, such as the water level control structure disclosed in Chinese Patent CN216748547U, which uses a float to determine the water level in the tank body, and when the water level in the tank body reaches a low water level, the water outlet pipe is forced to shut off. However, this mechanism cannot determine the change in water level during the water inflow, that is, it cannot determine whether the water level in the tank body reaches the target water level during the water inflow. If the water level in the tank body is not known during the water inflow, water overflow may occur, which not only causes waste of water resources, but also may affect the service life of the tank body or the safety of its movement. Therefore, the utility model provides a concentrated water tank water level control system and a water storage tank to improve the practicability of the water level control system and the safety of the water storage tank.

[0025] In the first aspect, as shown in the accompanying drawings Figure 1 Figure 1 The dashed box in the figure represents the tank body. The utility model provides a concentrated water tank water level control system, which comprises a detection rod 1 arranged in the tank body. The upper end of the detection rod 1 comprises a mounting seat 11. A limiting part 2 and a mounting ring 3 are arranged on the mounting seat 11. The mounting ring 3 is fixed at the position of the center of the limiting part 2. The mounting ring 3 is hung on a movable rod 4. The other end of the movable rod 4 is provided with a floating ball 41. The limiting part 2 comprises a hollow plate 21. The movable rod 4 is used to move in the area defined by the hollow plate 21. One side of the hollow plate 21 is provided with a positioning plate 22. The two ends of the positioning plate 22 are connected with the surface of the mounting seat 11. The positioning plate 22 comprises a plurality of information emitting ends which are uniformly distributed in a circular arc shape. The surface opposite to the positioning plate 22 of the movable rod 4 is provided with an information receiving end.

[0026] As described above, the concentrated water tank water level control system provided in the utility model comprises a detection rod 1 which is deeply arranged in the tank body. The upper end of the detection rod 1 is provided with a mounting seat 11. The mounting seat 11 comprises a movable rod 4 which is movably connected and a limiting part 2 which is used to detect the specific water level. The floating ball 41 is arranged at one end of the movable rod 4. The angle between the movable rod 4 and the detection rod 1 is different under different water levels. The information receiving end on the movable rod 4 receives the signals emitted by the information emitting ends at different positions, so that the water level in the tank body can be determined. As more and more concentrated water is injected into the tank body, the angle between the movable rod 4 and the detection rod 1 becomes larger and larger. When the two are perpendicular, it indicates that the water injection standard is reached. Similarly, when the concentrated water in the tank body is continuously discharged, the water quantity in the tank body decreases, the angle between the movable rod 4 and the detection rod 1 becomes smaller and smaller, and finally reaches a preset critical angle, which indicates that the minimum water level in the tank body is reached at this time, and the water discharge should be stopped.​

[0027] The preset critical value is related to the lowest water level in the actual tank body, and is a parameter set according to the actual situation, and the present description does not make specific limitations.

[0028] In addition, the outer surface of the lower end of the detection rod 1 is provided with threads, which are matched with the support seat 5 connected with the inner wall of the tank body or arranged through the tank body. The hand wheel 6 is connected with the support seat 5 through a connecting rod, and the hand wheel 6 is arranged to control a transmission mechanism in the support seat 5 to extend or contract the detection rod 1 along the length direction thereof. The detection rod 1 is connected with the mounting seat 11 through a bearing. Figure 2 As shown in the figure, the transmission mechanism comprises a first gear 7 and a second gear 8 perpendicular to each other, the first gear 7 is connected with the connecting rod, and the second gear 8 is used for meshing with the teeth at the lower end of the detection rod 1.

[0029] The operator rotates the hand wheel 6 to drive the first gear 7 to rotate, and the second gear 8 meshing therewith rotates synchronously. Because the second gear 8 meshes with the connecting wheel provided with teeth on the detection rod 1, the detection rod 1 arranged in the center of the connecting wheel moves upward or downward relative to the support seat 5, thereby adjusting the position of the detection rod 1. Because the highest water level or the lowest water level of the concentrated water stored in the tank body needs to be changed, the position of the detection rod 1 needs to be adjusted, and the adjustment direction, adjustment size and the like need to be adaptively selected according to the water level requirements of the actual tank body, and the present embodiment does not make specific limitations.

[0030] In addition, the utility model still includes water inlet, electronic valve, control terminal, electronic valve is connected with the water inlet pipe outside the water inlet, control terminal is located in the tank body outer wall (of course this control terminal still can install independently in other control equipment outside the tank body), and be provided with electronic valve, information transmitting end, information receiving end signal connection. The control terminal is used for displaying the real-time dynamic of the liquid level in the tank body and the danger or warning information; still include using this control terminal adjusts the position of detection, controls electronic valve's off, controls the action of water inlet or water outlet of water inlet; still include using this control terminal obtains detection signal and calculates real-time water level value according to detection signal.

[0031] It can be implemented that the information transmitting end is an infrared emitter, and the information receiving end is an infrared receiver. It can also be implemented that the information transmitting end is a Hall sensor transmitting end, and the information receiving end is a Hall sensor receiving end. The detection accuracy of infrared signals is high, and when the liquid level changes slightly, the liquid level value corresponding to the detection point can be stably obtained. However, when some liquids affect the propagation of infrared light or the refraction of infrared light is large, a Hall sensor can be used to detect the liquid level value of each detection point.

[0032] Additionally, the liquid outlet at the bottom of the tank in this invention, such as Figure 3 As shown, a sealing plug 9 is provided at the liquid outlet. The top surface of the sealing plug 9 includes an iron block. A mounting bracket is provided around the liquid outlet, and a relay 10 is fixed inside the mounting bracket. The relay 10 is used to connect and disconnect with the iron block to control the opening and closing of the liquid outlet. That is, the relay 10 controls the closing of the liquid outlet. When liquid needs to be discharged, the relay 10 is energized to pull the sealing plug 9 downward, thus opening the liquid outlet.

[0033] It is feasible to have an angle range of 3° or greater between adjacent information transmitting ends. The size of this angle determines the density of the detection point distribution; the denser the detection points, the higher the accuracy of liquid level change detection. Other angles such as 5°, 15°, 30°, or 45° can be selected, and can be adaptively adjusted according to parameters such as the length of the movable rod 4 and the diameter of the tank in actual use.

[0034] Secondly, based on the aforementioned concentrated water tank level control system, this utility model also provides a water storage tank, the external structure of which is the same as the internal structure. Figure 3 As shown, the tank can be installed vertically or horizontally. The tank can automatically control the liquid level stored in the tank and can automatically control the liquid to enter or exit the tank according to the liquid entry and exit requirements. It will not cause overflow or external liquid pumping equipment to run dry due to the inability to determine the liquid level in the tank, thus effectively improving the safety and practicality of the water storage tank.

[0035] In addition, the aforementioned water storage tank also includes an overflow pipe 12 and a pressure alarm 13. The overflow pipe 12 is connected to the top of the tank, and the pressure alarm 13 is plugged into the tank. The overflow pipe 12 is used to discharge liquid from the tank when an overflow occurs due to a malfunction in the liquid level detection system, thus protecting the safety of the tank. The pressure alarm 13 is installed at the lowest liquid level of the tank. When the liquid level in the tank is within a preset minimum liquid level range, the pressure at that location is within a certain range. When the pressure is less than the preset pressure value, it indicates that the liquid level in the tank has reached the minimum liquid level, thus warning the operator to close the outlet in time. The overflow pipe 12 and the pressure alarm 13 are the second physical guarantee for the safety of the tank. When the liquid level control system in the pipe malfunctions, this guarantee can improve the normal use of the tank and ensure its safety, further enhancing the practicality of the water storage tank.

[0036] Finally, the utility model provides a kind of water level control system and water storage tank of thick water tank, water level control system, including the detection rod 1 being set in tank body, the upper end of detection rod 1 includes mounting seat 11, mounting seat 11 is equipped with limiting portion 2 and mounting ring 3, mounting ring 3 is fixed in the position of the center of limiting portion 2, mounting ring 3 is equipped with and is hung with movable rod 4, movable rod 4 another end is equipped with float 41;Limiting portion 2 includes hollow plate 21, movable rod 4 is used to move in the area defined by hollow plate 21, one side of hollow plate 21 is equipped with positioning plate 22, the both ends of positioning plate 22 are connected with the surface of mounting seat 11, positioning plate 22 includes a plurality of information transmitting ends according to the uniform distribution of circular arc, the opposite face of movable rod 4 and positioning plate 22 is equipped with information receiving end.The utility model improves the practicality of water level control system, also improves the practicality and security of water storage tank use.
