Description

Technical Field

[0001] This application relates to the field of flow control technology, specifically to a liquid supply device. Background Technology

[0002] To meet the requirements of sustainable development in mining, backfill paste needs to be transported to designated areas both above and below ground for backfilling. Backfill paste is made by mixing various materials such as coal ash, cement, water, and coal gangue according to a certain mass measurement, and then controlling the concentration and strength to achieve the required level.

[0003] During the preparation of the filling paste, the water pump should not be frequently started and stopped at high intensity to avoid damaging critical components such as the motor. For example, to regulate the liquid volume in the metering hopper, it is necessary to control the opening and closing of the pneumatic butterfly valve to switch the liquid supply route. When the pneumatic butterfly valve closes instantly, the flow direction of the fluid in the pipeline changes. The pneumatic butterfly valve prevents the fluid from flowing to the metering hopper, causing the fluid to experience an impact exceeding 1.60 MPa. This results in a sudden surge in pressure in the pipeline and the pneumatic butterfly valve, causing strong vibrations and generating a water hammer effect, which can easily damage components such as the pneumatic butterfly valve.

Detailed Implementation

[0031] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0032] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0033] Currently, in the preparation of filling pastes, to control the liquid volume in the metering hopper, it is necessary to control the opening and closing of regulating valves, such as pneumatic butterfly valves, to switch the liquid supply route. When the pneumatic butterfly valve closes momentarily, the flow direction of the fluid in the pipeline changes. The pneumatic butterfly valve prevents the fluid from flowing into the metering hopper, causing an impact exceeding 1.60 MPa, resulting in a sudden surge in pressure in the pipeline and the pneumatic butterfly valve, strong vibration, and water hammer effect, which can easily damage components such as the pneumatic butterfly valve. To solve the above problems, such as... Figure 1 As shown, an embodiment of this application provides a liquid supply device 10, which may include: a first container 11, a second container 12, and an adjusting member 13.

[0034] The first container 11 is provided with an inlet and an outlet. The first container 11 can be of any shape or structure. For example, if the fluid has high environmental requirements, such as cleanliness, the first container 11 can be a closed structure. If there are no special requirements for the fluid, the first container 11 can be a semi-closed structure; for example, the top of the first container 11 can be open. The cavity of the first container 11 can be used to store fluids such as water or slurry. The inlet of the first container 11 is for allowing fluid to flow into the first container 11, and the outlet is for allowing the fluid to flow out of the first container 11. Figure 2 , Figure 3As shown, the liquid inlet section may include a liquid inlet 112 opened on the first container 11, or a liquid inlet pipe 113 or other pipes or pipe groups suspended above the first container 11, so as to allow a single fluid or multiple fluids to flow into the first container 11.

[0035] A fluid channel is provided between the second container 12 and the first container 11. In this embodiment, the second container 12 can be connected to the first container 11. For example, the second container 12 can be fixed to the first container 11 and configured with a fluid channel. In some other embodiments, the second container 12 can also be unconnected to the first container 11. For example, the second container 12 can be located below the first container 11, so that the first container 11 and the second container 12 can form a fluid channel through the height difference, and the fluid in the first container 11 can flow into the second container 12 under the action of gravity.

[0036] The fluid channel between the second container 12 and the first container 11 allows fluid in the first container 11 to flow into the second container 12, enabling flexible adjustment of the fluid storage capacity in the first container 11 according to actual production conditions. The fluid channel can be formed based on the actual shape and structure of the first container 11 and the second container 12, or it can be an independent structure connected to both. The second container 12 can also have any shape or structure. The volumes of the second container 12 and the first container 11 can be set according to actual needs. For example, the volume of the second container 12 can be smaller than the volume of the first container 11 to reduce equipment manufacturing costs or equipment size; the volume of the second container 12 can also be greater than or equal to the volume of the first container 11 to provide a higher capacity for holding and regulating the fluid in the first container 11.

[0037] like Figure 2 As shown, the second container 12 can be disposed on one side or at the bottom of the first container 11. This allows the fluid in the first container 11 to flow into the second container 12 under gravity when the liquid level in the first container 11 is higher than the liquid level in the second container 12. In other embodiments, the second container 12 can also be disposed at any position relative to the first container 11 and powered to allow the fluid in the first container 11 to flow into the second container 12 via a fluid channel. The fluid flowing into the second container 12 can be further recycled and reused, for example, by providing a fluid outflow channel or a fluid conveying device on the second container 12 to direct the fluid in the second container 12 to a target location.

[0038] The regulating member 13 is movably disposed in the fluid channel to regulate the flow of fluid from the first container 11 into the second container 12 via the fluid channel. For example... Figure 1 , Figure 2As shown, the regulating member 13, located in the fluid channel, can control the opening and closing of the fluid channel or the flow area of ​​the fluid in the fluid channel by moving it, or by rotating it, thereby regulating the flow of fluid from the first container 11 into the second container 12. For example, the regulating member 13 can be moved to the closed position, preventing the fluid in the first container 11 from flowing into the second container 12 through the fluid channel; the regulating member 13 can be moved to the fully open position, allowing the fluid in the first container 11 to flow into the second container 12 with the maximum possible flow capacity; the regulating member 13 can be moved to a preset open position, allowing the fluid in the first container 11 to flow into the second container 12 with a preset flow capacity; here, the fluid capacity can be the fluid velocity or flow rate. Furthermore, the regulating member 13 can be adjusted manually, by power drive, or by a monitoring device installed on-site, allowing remote control adjustment of the regulating member 13 based on the on-site conditions captured by the monitoring device.

[0039] The liquid supply device 10 provided in the embodiments of this application includes: a first container 11, a second container 12, and an adjusting member 13; the first container 11 is provided with a liquid inlet and a liquid outlet; a fluid channel is provided between the second container 12 and the first container 11; the adjusting member 13 is movably disposed in the fluid channel to adjust the flow of fluid in the first container 11 into the second container 12 through the fluid channel. By utilizing the adjusting member 13 disposed on the fluid channel of the first container 11 and the second container 12, the liquid supply device 10 allows the fluid in the first container 11 to flow into the second container 12, thereby regulating the amount of fluid stored in the first container 11 and facilitating the adjustment of fluid usage.

[0040] To reduce workload and improve the convenience and automation of fluid volume adjustment, optionally, in one embodiment of this application, a driving member 14 is included for driving the adjusting member 13 to move to a preset position; the driving member 14 includes a rod 141 and a rotatable column 142, the outer wall of the column 142 is provided with a guide groove 1420, the first end of the rod 141 is connected to the adjusting member 13, the second end of the rod 141 extends into the guide groove 1420, and the second end of the rod 141 is slidably connected to the guide groove 1420.

[0041] In this embodiment, as Figure 4As shown, the adjustment member 13 is moved and adjusted by a drive member 14 driven by power. This drive member has a rotatable column 142, which can be driven to rotate by a motor, for example. The guide groove 1420 on the outer wall of the column 142 has a preset trajectory and contour shape. As the circumferential position of the guide groove 1420 along the outer wall of the column 142 changes, its axial position also changes. Thus, during the rotation of the column 142, the second end of the rod 141, which is slidably connected to the guide groove 1420, can move along the axial direction of the column 142 under the action of the guide groove 1420. The adjustment member 13, connected to the first end of the rod 141, moves under the influence of the rod 141, thereby controlling the opening and closing of the fluid channel or the flow area of ​​the fluid in the fluid channel. Therefore, in this embodiment, the drive member 14, by providing the guide groove 1420 on the outer wall of the column 142, converts the rotation of the column 142 into the translation of the rod 141 and the adjustment member 13.

[0042] The guide groove 1420 on the outer wall of the column 142 can be a closed annular structure. As the column 142 rotates in one direction, the second end of the rod 141, which is slidably connected to the guide groove 1420, can reciprocate along the axial direction of the column 142. Alternatively, the guide groove 1420 on the outer wall of the column 142 can be a non-closed arc structure, allowing the second end of the rod 141, which is slidably connected to the guide groove 1420, to also reciprocate along the axial direction of the column 142 through the forward and reverse rotation of the column 142. In this embodiment, the motor driving the column 142 to rotate can be equipped with a backstop to prevent the motor from rotating in the opposite direction after the adjusting member 13 moves to the preset position, thereby preventing the adjusting member 13 from stably stopping at the preset position. In other embodiments, a backstop structure may be provided for the column 142 or the rod 141. For example, the guide groove 1420 on the outer wall of the column 142 and the second end of the rod 141 may be designed to have a self-locking function. After the adjusting member 13 moves to the preset position, the friction between the second end of the rod 141 and the guide groove 1420 will self-lock, so that the friction between the second end of the rod 141 and the guide groove 1420 is not less than the force of the second end of the rod 141 sliding down the guide groove 1420, thereby making the adjusting member 13 stably stay in the preset position.

[0043] In one embodiment of this application, an inclined rod may be provided between the adjusting member 13 and the rod body 141, with one end of the inclined rod connected to the adjusting member 13 and the other end connected to the rod body 141, thereby improving the support strength and reliability of the rod body 141 for the adjusting member 13.

[0044] Optionally, in one embodiment of this application, such as Figure 5 , Figure 6As shown, it also includes a slide groove 15, and the adjusting member 13 has a plate-like structure and is slidably connected to the slide groove 15. The plate-like adjusting member 13 slides along the slide groove 15, which can quickly adjust the flow area of ​​the fluid channel, thus improving the response speed of the adjusting member 13. In addition, the setting of the slide groove 15 also facilitates the configuration of a sealing structure for the adjusting member 13, for example, a sealing member 18 can be set at the groove wall of the slide groove 15 to improve the sealing contact capability between the adjusting member 13 and the slide groove 15.

[0045] In this embodiment, the position of the chute 15, the number of chute 15, and the sliding direction of the adjusting member 13 can be set according to specific circumstances. For example, a chute 15 can be set at the bottom of the fluid channel, and the adjusting member 13 can move left and right along the chute 15. Alternatively, the chute 15 can be set on the side of the fluid channel, and the adjusting member 13 can move up and down along the chute 15. The adjusting member 13 is a plate-shaped structure. For example, the adjusting member 13 can be a single plate or it can include multiple plates. For example, the adjusting member 13 can include a front plate and a rear plate. The two sides of the front plate can slide along the chute 15, one side of the rear plate is connected to the front plate, and the other side of the rear plate can be connected to the rod 141. It can be understood that the adjusting member 13 including the front plate and the rear plate is beneficial to improving the structural strength of the adjusting member 13 and is also beneficial to the differentiated configuration of different structural parts of the adjusting member 13. For example, the front plate can be made of wear-resistant, pressure-resistant, or corrosion-resistant materials, and the rear plate can be made of materials with higher structural strength.

[0046] To improve the reliability and stability of the sliding of the adjusting member 13 along the slide groove 15, optionally, in one embodiment of this application, at least two slide grooves 15 are provided, with the two slide grooves 15 located on both sides of the fluid channel, and the two sides of the adjusting member 13 slidably connected to the two slide grooves 15 respectively. By providing two slide grooves 15, the two sides of the adjusting member 13 can simultaneously receive the supporting force of the slide grooves 15 and slide along the slide grooves 15. This provides the adjusting member 13 with more stable and reliable force support during sliding, avoiding jamming. Furthermore, providing two slide grooves 15 also facilitates the simultaneous provision of sealing members 18 on the groove walls of the two slide grooves 15, ensuring the sealing performance of the adjusting member 13 when regulating the fluid flow through the fluid channel.

[0047] Optionally, in one embodiment of this application, such as Figure 6As shown, the second container 12 has at least a first plate 161 and a second plate 162 on the side near the first container 11, and a groove 15 is formed between the first plate 161 and the second plate 162. The outer wall of the second container 12 can be made of sheet metal. The first plate 161 and the second plate 162 can be provided on the side of the second container 12 near the first container 11, so that there can be a reserved space between the first plate 161 and the second plate 162 to form the groove 15. A sealing element 18 can also be provided between the first plate 161 and the second plate 162, so that the first plate 161, the second plate 162 and the sealing element 18 form the groove 15.

[0048] In this embodiment, a first plate 161 and a second plate 162 can be respectively provided on both sides of the fluid channel, thereby forming grooves 15 on both sides of the fluid channel. A notch can be opened on the side wall of the first container 11 near the second container 12, and a fluid channel can be formed along the notch on the side wall of the first container 11, the first plate 161, and the second plate 162. Furthermore, a flow guiding structure, such as a flow guide plate, can be provided along the fluid channel to facilitate the flow of fluid in the fluid channel.

[0049] Optionally, in one embodiment of this application, such as Figure 6 , Figure 7 As shown, a third plate 163 is provided on the side of the second plate 162 away from the first plate 161. An elastic column 171 is provided between the third plate 163 and the second plate 162. A tube 172 is inserted through the elastic column 171 along the axial direction. The length of the tube 172 is less than the length of the elastic column 171. The second plate 162 is provided with a first end connector 173 connected to the first end of the tube 172, and / or the third plate 163 is provided with a second end connector 174 connected to the second end of the tube 172.

[0050] In this embodiment, as Figure 7 , Figure 8 As shown, an elastic post 171 is provided between the third plate 163 and the second plate 162, which enables an elastically adjustable connection between the third plate 163 and the second plate 162. Specifically, as shown... Figure 7 , Figure 9As shown, the elastic column 171 can be a hollow tubular structure made of rubber, through which a tube 172 can be inserted along the axial direction. The axial length of the tube 172 is less than the axial length of the elastic column 171. The first and second ends of the tube 172 can be internally threaded. Through holes can be opened at corresponding positions on the second plate 162, and a first end connector 173 connected to the first end of the tube 172 can be inserted. For example, the first end connector 173 can be a bolt threaded to the first end of the tube 172. A through hole is also opened at a corresponding position on the third plate 163, and a second end connector 174 connected to the second end of the tube 172 can be inserted. For example, the second end connector 174 can also be... The bolt is threaded to the second end of the tube body 172. In this way, by adjusting the threaded connection length between the first end connector 173 and the first end of the tube body 172, and / or adjusting the threaded connection length between the second end connector 174 and the second end of the tube body 172, the relative distance between the second plate 162 and the third plate 163 can be changed, thereby changing the compression of the elastic column 171 between the second plate 162 and the third plate 163. This allows the relative distance between the second plate 162 and the first plate 161 to be adjusted, which in turn adjusts the groove width of the slide groove 15. This ensures that the size of the adjusting member 13 matches that of the slide groove 15, allowing the adjusting member 13 to slide smoothly along the slide groove 15 and to form a good sealing effect with the slide groove 15.

[0051] In other embodiments, a through hole can be made at a corresponding position on the second plate 162, and a first end connector 173 connected to the first end of the tube 172 can be inserted through it. For example, the first end connector 173 can be a bolt and threadedly connected to the first end of the tube 172, while the third plate 163 is fixedly connected to the second end of the tube 172. The relative distance between the second plate 162 and the third plate 163 can be changed by adjusting the threaded connection length between the first end connector 173 and the first end of the tube 172. Alternatively, a through hole can also be made at a corresponding position on the third plate 163, and a second end connector 174 connected to the second end of the tube 172 can be inserted through it. For example, the second end connector 174 can also be a bolt and threadedly connected to the second end of the tube 172, while the second plate 162 is fixedly connected to the first end of the tube 172. The relative distance between the second plate 162 and the third plate 163 can be changed by adjusting the threaded connection length between the second end connector 174 and the second end of the tube 172.

[0052] In one embodiment of this application, such as Figure 9As shown, the first end and the second end of the elastic column 171 have a first outer diameter, and the portion between the first end and the second end of the elastic column 171 has a second outer diameter, wherein the first outer diameter is larger than the second outer diameter. This design of the elastic column 171 allows the first end and the second end of the elastic column 171 to have a larger contact area with the second plate 162 and the third plate 163, respectively, which is beneficial to improving the stability of the support connection.

[0053] There can be multiple elastic columns 171 provided between the third plate 163 and the second plate 162, for example, more than two. Multiple elastic columns 171 located between the third plate 163 and the second plate 162 are arranged along the length direction of the slide groove 15, so that the groove width of the slide groove 15 at different local positions along the length direction can be adjusted, avoiding local jamming and improving the ability to adjust the sliding connection performance and sealing performance between the adjusting member 13 and the slide groove 15.

[0054] Optionally, in one embodiment of this application, such as Figure 6 As shown, the second plate 162 has a sealing element 18 on the side near the first plate 161; and / or the first plate 161 has a sealing element 18 on the side near the second plate 162. The sealing element 18 can be connected to either the second plate 162 or the first plate 161. The sealing element 18 can be made of rubber; for example, it can be a plate-like structure connected to the second plate 162, forming a seal between the adjusting member 13 and the second plate 162. Alternatively, the sealing element 18 can be an L-shaped structure connected to the second plate 162, forming a seal between the adjusting member 13 and the second plate 162, and also forming a seal between the adjusting member 13 and the bottom of the groove 15.

[0055] To further improve the sliding flexibility of the adjusting member 13 in the slide groove 15, optionally, in one embodiment of this application, such as Figure 10 As shown, a pin 1611 is provided on the first plate 161, and a rolling element 1612 is sleeved on the pin 1611. The rolling element 1612 can roll in contact with the adjusting member 13. In this embodiment, the pin 1611 and the rolling element 1612 on the first plate 161 can be set according to the specific configuration of the adjusting member 13 and the slide groove 15. For example, the rolling element 1612 can be configured to roll in contact with the side of the adjusting member 13 away from the second plate 162, or the rolling element 1612 can be configured to roll in contact with the side of the adjusting member 13 facing the bottom of the slide groove 15. The number of pins 1611 and corresponding rolling elements 1612 provided on the first plate 161 can be multiple, for example, two or more. Multiple pins 1611 and corresponding rolling elements 1612 sleeved on each pin 1611 can be arranged along the length direction of the slide groove 15 so that the adjusting member 13 can slide flexibly along the slide groove 15.

[0056] Optionally, in one embodiment of this application, such as Figure 2 As shown, the bottom of the first container 11 is funnel-shaped; specifically, the first container 11 can be a measuring hopper with a measuring function, which can monitor parameters such as the mass or volume of the stored fluid. The funnel-shaped bottom is conducive to setting up a liquid outlet, so that the fluid can be discharged from the first container 11.

[0057] Optionally, in one embodiment of this application, the first container 11 is provided with a vent 110; such as Figure 2 As shown, the vent 110 facilitates the injection or discharge of fluid into or from the first container 11. For example, when fluid is injected into the first container 11, the gas inside the first container 11 can be discharged through the vent 110. When fluid is discharged from the first container 11, the gas outside the first container 11 can enter the first container 11 through the vent 110, so that the gas pressure on the liquid surface inside the first container 11 remains constant, and the injection or discharge of fluid is not affected by the change in gas pressure inside the first container 11 during the injection or discharge of fluid.

[0058] Optionally, in one embodiment of this application, the first container 11 is provided with a metering element 111 to detect the amount of fluid stored in the first container 11; such as Figure 2 As shown, the measuring element 111 can be a pressure sensor installed on the support of the first container 11, which calculates the amount of fluid stored in the first container 11 based on the pressure change of the support of the first container 11.

[0059] Optionally, in one embodiment of this application, such as Figure 1 , Figure 2 , Figure 3As shown, the liquid inlet of the first container 11 includes a liquid inlet 112 disposed at the top of the first container 11 and a liquid inlet pipe 113 that can communicate with the liquid inlet 112. The liquid inlet pipe 113 is at least partially a flexible tube. In this embodiment, the liquid inlet 112 can be opened at the top of the first container 11, and the liquid inlet pipe 113 can be suspended at the top of the first container 11. The first end of the liquid inlet pipe 113 can be connected to the liquid supply path, and the second end of the liquid inlet pipe 113 can be connected to the liquid inlet 112. For example, the second end of the liquid inlet pipe 113 can be suspended above the liquid inlet 112 to facilitate switching the position of the second end of the liquid inlet pipe 113 and supplying fluid. Fluid output from equipment such as a water tank or pool can flow into the first container 11 from the second end of the inlet pipe 113 through the inlet port 112 via the liquid supply path. For example, when the metering device 111 detects that the amount of fluid stored in the first container 11 has reached a preset value, the second end of the inlet pipe 113 can be moved so that the second end of the inlet pipe 113 is switched from the position above the inlet port 112 to the return position. When the second end of the inlet pipe 113 is switched to the return position, the fluid flowing out from the second end of the inlet pipe 113 no longer flows into the inlet port 112 and the first container 11, but flows back to the fluid supply equipment via the return path.

[0060] Furthermore, configuring the inlet pipe 113 as at least partially a flexible tube facilitates switching the position of the second end of the inlet pipe 113, reduces the impact of fluid flow, and facilitates the connection between the inlet pipe 113 and the fluid supply path. In some embodiments, the second end of the inlet pipe 113 may extend into the first container 11 to reduce the drop of fluid from the second end of the inlet pipe 113 into the first container 11, thereby avoiding affecting the measurement accuracy of the metering element 111, such as a pressure sensor.

[0061] Optionally, in one embodiment of this application, such as Figure 2 As shown, the liquid outlet of the first container 11 includes a liquid outlet 114 located at the bottom of the first container 11 and a liquid outlet pipe 115 connected to the liquid outlet 114. The liquid outlet pipe 115 is at least partially a flexible tube. The liquid outlet 114 can be located at the funnel-shaped bottom of the first container 11. Configuring the liquid outlet pipe 115 to be at least partially a flexible tube also helps to reduce the impact of fluid flow and facilitates the connection of the liquid outlet pipe 115 to other pipes.

[0062] Optionally, in one embodiment of this application, such as Figure 2 As shown, the liquid outlet of the first container 11 is equipped with a regulating valve 116. Specifically, the regulating valve 116 can be a butterfly valve, such as a pneumatic butterfly valve. This butterfly valve can be connected to the mixer through a pipeline. By adjusting the opening and closing of the butterfly valve, the fluid in the first container 11 can be supplied to the mixer and other equipment according to the production status of the mixer.

[0063] Optionally, in one embodiment of this application, such as Figure 2As shown, the second container 12 is provided with an outlet 120; and / or the second container 12 is provided with a clearance groove 121 along the moving direction of the adjusting member 13. The outlet 120 of the second container 12 can also be connected to the return flow path, so that the fluid in the second container 12 can also flow back to the fluid supply equipment through the return flow path. In the embodiments of this application, as Figure 5 As shown, the second container 12 has a clearance groove 121 along the moving direction of the adjusting member 13, which can form a clearance space for the driving member 14, which is beneficial to make full use of the space structure of the equipment and reduce the structural volume. For example, the rod 141 of the driving member 14 can pass through the clearance groove 121, so that the first end of the rod 141 is connected to the adjusting member 13 and drives the adjusting member 13 to move.

[0064] Optionally, in one embodiment of this application, such as Figure 1 , Figure 2 As shown, it also includes a support base 191, with the first container 11 mounted on the support base 191. The support base 191 is also connected to a bracket 192, and a driving component 14 is mounted on the bracket 192. The support base 191 and the bracket 192 can be made of channel steel or the like. The support base 191 can be a rectangular frame structure, with the first container 11 inserted and fixed inside the rectangular frame. The bottom of the bracket 192 is connected to the support base 191, and the top of the bracket 192 is connected to the top of the first container 11. The driving component 14 can be fixedly suspended on the bracket 192.

[0065] In the use of the above-described liquid supply device 10, fluid, such as water, in the fluid supply equipment can enter the first container 11 through the liquid supply path from the first end of the inlet pipe 113 configured on the first container 11, and flow into the first container 11 from the second end of the inlet pipe 113 through the inlet port 112. When the metering element 111 detects that the amount of fluid stored in the first container 11 has reached a preset value, the second end of the inlet pipe 113 can be moved so that the second end of the inlet pipe 113 is switched from a position above the inlet port 112 to a return position. When the second end of the inlet pipe 113 is switched to the return position, the fluid flowing out from the second end of the inlet pipe 113 no longer... Instead of flowing into the inlet 112 and the first container 11, the fluid flows back to the fluid supply equipment via the return flow path. This ensures that the pump in the fluid supply path that supplies fluid to the first container 11 is always on and in operation, avoiding water hammer effects caused by frequent opening and closing. It also simplifies the components of the fluid supply path. For example, using the fluid supply device 10 in this embodiment, compared to traditional fluid supply methods, the slow-closing check valve, water hammer absorber, electric ball valve, metal hose, rubber shock absorber, pneumatic butterfly valve, etc., in the fluid supply path that supplies fluid to the first container 11 can be eliminated, which helps to reduce equipment costs and improve the working reliability and service life of the fluid supply path.

[0066] When the fluid, such as water, in the first container 11 meets the quality or weight requirements, the regulating valve 116, such as a butterfly valve, located at the bottom outlet of the first container 11 can be opened, allowing the fluid in the first container 11 to flow into the mixer. Since the mixer often requires a certain amount of time to achieve uniform mixing when mixing a batch of materials such as coal ash, coal gangue, cement, or water, the liquid supply device 10 of this application allows for the movable adjustment element 13 that opens the fluid channel between the first container 11 and the second container 12, enabling excess fluid stored in the first container 11 to flow into the second container 12 through the fluid channel. The fluid flowing into the second container 12 can then flow back to the fluid supply equipment from the outlet 120 of the second container 12 via the return flow path, allowing the fluid in the second container 12 to be recycled. Through this method, the mixer can operate intermittently and repeatedly, achieving a constant liquid supply and uniform mixing.
