Therefore, to ensure stable water supply in each water supply loop, a coordinated water supply system for the entire area is needed to address the problem of fluctuating water supply flow within the laterite nickel ore smelting production plant.

[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0027] As shown in FIG1 , the present invention provides a coordinated water supply system for the entire area, including a water supply unit 1 and a balancing unit 2. The water supply unit 1 is arranged adjacent to the water-using end and is connected to a main water supply pipeline 3 for storing water and directly delivering the stored water to the water-using end. The water source is stored at the water-using end to provide a buffer space for water supply, thereby offsetting the pressure and flow fluctuations during the water source delivery process. The water source is directly delivered at a position close to the water-using end, thereby avoiding the problems of excessively long pipelines and fluctuations in water source supply flow, and ensuring stable water supply at the water-using end. The balancing unit 2 is provided with a main water supply pipeline 3 for storing water and directly delivering the stored water to the water-using end. Unit 2 is arranged between multiple water supply units 1 and is used to connect adjacent water supply units 1. When the water storage capacity of a certain water supply unit 1 is insufficient, the stored water of the adjacent water supply unit 1 is transferred to supplement the water supply unit 1 with insufficient water storage. In order to avoid the insufficient water supply rate caused by the rapid water consumption of a single water supply unit 1, the water stored in the adjacent water supply units 1 is interconnected, so that the water supply unit 1 with insufficient water supply can be supplemented in time, and a multi-channel water source supply is formed with the water supply pipeline, thereby improving the water supply rate and quickly replenishing the water supply unit 1.

[0028] It can be understood that with the setting of the water supply unit 1, the water supply fluctuations generated by the delivery part are solved at the water supply end in the form of water supply buffering. The structure is simple and easy to operate. Moreover, with the connection of multiple water supply units 1 by the balancing unit 2, the stored water of the water supply units 1 can be called upon to each other, and the closest water supply unit 1 can be called the fastest, which can quickly respond to sudden water supply shortages and has an overall synergistic effect.

[0029] In a certain embodiment, the water supply unit 1 includes a water tank 11 and a water pump 12. The pumping end of the water pump 12 is provided with a pumping pipe 13, and the pumping pipe 13 is inserted into the interior of the water tank 11. The end of the main water supply pipeline 3 is set at the top of the water tank 11. The water in the water tank 11 is directly extracted by the water pump 12 through the pumping pipe 13 and transported to the water end, while the main water supply pipeline 3 continuously transports water from the top of the water tank 11 to the interior thereof to form water replenishment, and the water tank 11 is a buffer part at the end of the water supply route to buffer the fluctuation of water supply.

[0030] It can be understood that the pumping pipe 13 is extended as far as possible to the bottom of the water storage tank 11, and several branch pipes are provided on the main water supply pipe 3, which are connected to individual water supply units 1 through the branch pipes, and electric control valves are provided on the branch pipes to control the opening and closing of the corresponding flow paths.

[0031] In a certain embodiment, the balancing unit 2 includes an interflow pipe 21, which is arranged between adjacent water storage tanks 11 and connects the water storage tanks 11. Under the action of atmospheric pressure, the water in the water storage tank 11 with a large water storage capacity is interconnected to the inside of the water storage tank 11 with insufficient water storage capacity to supplement the water used by the water supply unit 1 with insufficient water storage capacity.

[0032] The water storage tank 11 may be a cylindrical narrow and high tank body to increase the depth of the water storage so as to provide sufficient water pressure when the water flows.

[0033] It can be understood that when the water storage volume in the water storage tank 11 is lower than the bottom of one end of the mutual flow pipe 21, the mutual flow pipe 21 acts as an overflow pipe from one water storage tank 11 and overflows into the water storage tank 11 with lower water volume; when the water storage volume in the water storage tank 11 is higher than one end of the mutual flow pipe 21, the liquid level of the other water storage tank 11 is higher than the liquid level height of the water storage tank 11, which is the principle of communicating vessels. Under the action of atmospheric pressure, water continues to be injected into the water storage tank 11 until the liquid levels of the two water storage tanks 11 are flush.

[0034] In a certain embodiment, the balancing unit 2 further includes a liquid level monitoring component 22 and a control valve 23. The liquid level monitoring component 22 is provided on the water storage tank 11 for monitoring the amount of water stored in the water storage tank 11. The control valve 23 is provided on the interflow pipe 21 for controlling the on-off of the interflow pipe 21. Under the monitoring of the liquid level monitoring component 22, the liquid level height of each water storage tank 11 can be fed back in real time, which is divided into the following situations:

[0035] First, if the liquid level is too high, the electric control valve of the water supply of the main water supply pipeline 3 corresponding to the water supply line is closed, and the water storage tank 11 is disconnected;

[0036] Secondly, if the liquid level is too low and the water supply speed cannot be connected, the control valve 23 of the interflow pipe 21 of the adjacent water storage tank 11 with a higher liquid level is opened to circulate water, perform active liquid level balance, and coordinate the water supply of the main water supply pipe 3 to achieve dual-path water supply;

[0037] Third, if the liquid level is too low and the interflow pipe 21 of an adjacent water storage tank 11 with a higher liquid level is opened, the liquid level rises and falls too slowly, then the interflow pipe 21 of the adjacent water storage tank 11 with a higher liquid level on the opposite side is opened to form a three-way water supply.

[0038] It can be understood that the liquid level monitoring component 22 can use a liquid level sensor or other equipment that can monitor the liquid level height. Under the liquid level monitoring, the real-time liquid level height and the rate of increase or decrease of the height can be obtained to control the number of coordinated water supply flow paths.

[0039] In addition, when a single water supply unit 1 does not need to supply water, water is accumulated. After sufficient water is accumulated, the electric control valve is closed and used as an emergency water supply unit. When coordinated water supply is needed, the control valve 23 of the corresponding direction interflow pipe 21 is opened.

[0040] In a certain embodiment, several adjacent water storage tanks 11 are connected in sequence through the interflow pipes 21. Referring to Figure 1, the water storage tanks 11 are connected and communicated one by one. Their main distribution arrangement is that when the production line is linear, they can be connected in sequence to achieve water source interflow balance. However, their disadvantage is that there are only three water supply routes, namely, upper, left and right, at most, and the water supply efficiency is limited.

[0041] Furthermore, several adjacent water storage tanks 11 are staggered and connected through multiple interflow pipes 21. Referring to FIG2 , when the production line is distributed in multiple rows and staggered, multiple water storage tanks 11 can be interconnected in multiple directions, thereby increasing the maximum water supply flow path, which is not limited to three-way water supply. Under this distribution, if a water supply problem occurs in one path, the other multiple paths can simultaneously supply water to supplement it, thereby accelerating the water supply balance.

[0042] It can be understood that the interflow pipes 21 are set up between the water storage tanks 11, mainly according to the distribution of the water-using end equipment. If the water-using end equipment is more concentrated, a staggered distribution can be adopted. If the water-using end equipment is more dispersed, a linear distribution can be adopted. If the water-using end equipment is irregularly distributed, the linear and staggered distributions can be appropriately mixed and used to form one more interflow pipe 21, which means one more water supply channel.

[0043] In a certain embodiment, a minimum water storage line is set in the water storage tank 11, and the position of the interflow pipe 21 corresponds to the position of the minimum water storage line and is slightly lower than the position of the minimum water level line. When the liquid level is lower than the minimum water level line, the adjacent water storage tank 11 can be opened for timely replenishment.

[0044] It is understandable that if the water supply of the adjacent water tank 11 drops below the minimum water level, the other water tank 11 adjacent to the adjacent water tank 11 can be opened to supply water to it, and the water supply can be connected one by one, so that the water supply can be connected in time. If the interflow pipe 21 is higher than or flush with the minimum water level, the liquid level of the water tank 11 supplying water will be lower than the minimum water level, and then the other adjacent water tank 11 will be opened. At this time, the interflow pipe 21 is already above the liquid level, resulting in an interruption of water supply, which is not conducive to the continuous interconnection of multiple water tanks 11.

[0045] In a certain embodiment, since the liquid level sensor is prone to malfunction due to environmental influences during long-term use, in order to avoid excessive maintenance and repair costs caused by such malfunction, referring to Figure 3, the liquid level monitoring component 22 includes a float 221 and a camera 222. The float 221 is provided with a scale 223. The camera 222 is provided on the top of the water storage tank 11 and faces the scale 223. The camera 222 captures the numbers on the scale 223, converts the image signal into a digital signal, and forms liquid level feedback.

[0046] It is understandable that machine vision is relatively mature at this stage, and the liquid level height value captured by the image signal can be converted into a digital signal to form a specific liquid level feedback. In addition, the cost of the float 221, camera 222 and scale 223 is relatively low, and if a single part is damaged, it is also easy to replace.

[0047] Furthermore, in order to improve the stability of the rise and fall of the float 221, the liquid level monitoring component 22 also includes a guide column 224, and the float 221 is sleeved on the outside of the guide column 224. The guide column 224 is used to guide the rising and falling direction of the float 221, wherein the float 221 is slidably connected to the guide column 224, and the guide column 224 is used to limit and guide the float 221 so that it can rise and fall vertically to prevent position displacement and skew, thereby improving the verticality of the scale 223 and improving the capture accuracy of the liquid level feedback.

[0048] Furthermore, in order to ensure sufficient brightness when capturing the image, the liquid level monitoring component 22 also includes a lighting lamp 225, which is arranged on the top of the water storage tank 11 and shines toward the scale 223, thereby preventing insufficient ambient light and unclear image capture, which may lead to incorrect liquid level feedback.

[0049] In a certain embodiment, since the water supply source is separated from the water-using equipment into a proximal end and a distal end, the water flow rate at the proximal end is fast and the water supply is sufficient, while the distal end is susceptible to fluctuations and the water flow rate is reduced. Therefore, in order to avoid insufficient water supply rate at the distal end, referring to Figure 4, a separate pipe is extended from the proximal water storage tank 11 close to the water source as an overflow pipe to accumulate backup water in the backup tank body 111, and the backup tank body 111 and the distal water storage tank 11 are connected to an interflow pipe 21 and are equipped with a control valve 23, thereby adding a water supply flow path, and the backup tank body 111 can be connected to multiple interflow pipes 21 to provide backup water for multiple distal water storage tanks 11.

[0050] It can be understood that the backup tank 111 is not only suitable for remote water-using equipment, but also can be used for water-using equipment that consumes more water, as a backup water source, to provide an additional collaborative water source.

[0051] The specific working process of the present invention is as follows: the water storage amount in the water tank 11 is monitored by the liquid level monitoring component 22. When the water level is lower than the lowest water level line, the float 221 moves down along the guide column 224 and the scale 223 is lowered. The corresponding image value is captured by the camera 222 and fed back to the background. Then, the control valve 23 on the upper interflow pipe 21 is opened to divert water from the water tank 11 on the adjacent water supply unit 1, and cooperate with the continuous water supply of the main water supply pipeline 3 to form a multi-channel water supply, prevent the water supply flow from decreasing or fluctuating, and maintain stable water supply.

[0052] The entire workflow is complete, and all contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0053] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
