Description

Technical Field

[0002] To meet the requirements of sustainable mining development, filling paste needs to be transported to designated areas above and below the mine for filling. Filling paste is a mixture of various materials such as fly ash, cement, water, and gangue, measured according to a certain mass, and then stirred to achieve the required concentration and strength.

[0003] During the preparation of filling pastes, in order to control the amount of liquid stored in the metering hopper, it is necessary to control the opening and closing of a pneumatic butterfly valve to switch the liquid supply route. The pneumatic butterfly valve closes instantly, changing the flow direction of the fluid in the pipeline. The pneumatic butterfly valve blocks the fluid from flowing into the metering hopper, causing the fluid to experience a shock of more than 1.60 MPa. This causes a sudden surge in pressure in the pipeline and the pneumatic butterfly valve, resulting in strong vibration and water hammer, which can easily damage the pneumatic butterfly valve and other components.

DETAILED DESCRIPTION

[0030] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0031] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] Currently, in the process of preparing filling pastes, in order to control the amount of liquid stored in the metering bucket, it is necessary to control the opening and closing of a regulating valve, such as a pneumatic butterfly valve, to switch the liquid supply route. The pneumatic butterfly valve closes instantly, and the flow direction of the fluid in the pipeline changes. The pneumatic butterfly valve prevents the fluid from flowing to the metering bucket, causing the fluid to generate an impact exceeding 1.60Mpa, causing an instantaneous pressure surge in the pipeline and the pneumatic butterfly valve, strong vibration, and water hammer effect, which can easily damage the pneumatic butterfly valve and other components. In order to solve the above problems, Figure 1 As shown, an embodiment of the present application provides a liquid supply device 10 , which may include: a first container 11 , a second container 12 , an adjusting member 13 and a driving member 14 .

[0033] The first container 11 is provided with a liquid inlet and a liquid outlet; the first container 11 can be of any shape or structure. For example, when there are high environmental requirements for the fluid, such as cleanliness requirements, the first container 11 can be a closed structure. When 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 accommodating cavity of the first container 11 can be used to store fluids such as water, slurry, etc. The liquid inlet of the first container 11 is used for allowing fluid to flow into the first container 11, and the liquid outlet is used for allowing fluid in the first container 11 to flow out. Figure 2 、 Figure 3 As shown, the liquid inlet portion may include a liquid inlet 112 opened on the first container 11 , or may include a pipe or pipe group such as a liquid inlet pipe 113 suspended above the first container 11 to allow a single fluid or multiple fluids to flow into the first container 11 .

[0034] The second container 12 is connected to the first container 11, and a fluid channel is provided between the second container 12 and the first container 11; the fluid channel allows the fluid in the first container 11 to flow into the second container 12, so as to flexibly adjust 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 the first container 11 and the second container 12. The second container 12 can also be of any shape or structure, and 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 that of the first container 11 to reduce the manufacturing cost or volume of the equipment, or the volume of the second container 12 can be greater than or equal to that of the first container 11 to have a higher capacity to accommodate and adjust the fluid in the first container 11.

[0035] like Figure 2 As shown, the second container 12 can be disposed on one side of the first container 11 or at the bottom of the first container 11. In this way, when the liquid level in the first container 11 is higher than the liquid level in the second container 12, the fluid in the first container 11 can flow into the second container 12 under the action of gravity. In other embodiments, the second container 12 can also be disposed at any position relative to the first container 11, and a power device can be used to allow the fluid 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 be further recycled and reused. For example, a fluid outflow channel or a fluid conveying device can be provided on the second container 12 to allow the fluid in the second container 12 to flow to a target location.

[0036] The regulating member 13 is movably disposed in the fluid channel to regulate the fluid in the first container 11 to flow into the second container 12 through the fluid channel. Figure 1 、 Figure 2As shown, the adjusting member 13 disposed in the fluid channel can be moved to control the opening and closing of the fluid channel or the flow area of the fluid in the fluid channel, or can be rotated to control the opening and closing of the fluid channel or the flow area of the fluid in the fluid channel, thereby regulating the flow of fluid from the first container 11 through the fluid channel to the second container 12. For example, the adjusting member 13 can be moved to a closed position, preventing the fluid from flowing through the fluid channel to the second container 12; the adjusting member 13 can be moved to a fully open position, allowing the fluid from the first container 11 to flow through the fluid channel to the second container 12 at the maximum possible flow capacity; the adjusting member 13 can be moved to a preset open position, allowing the fluid from the first container 11 to flow through the fluid channel to the second container 12 at a preset flow capacity. The flow capacity here can be the velocity or flow rate of the fluid. Furthermore, the adjusting member 13 can be adjusted manually, powered, or remotely controlled by installing a monitoring device on-site and capturing the on-site working conditions.

[0037] In order to reduce the workload and improve the convenience and automation of fluid dosage adjustment, a driving member 14 is provided in this embodiment, which is used to drive the adjusting member 13 to move to a preset position; the driving member 14 includes a rod body 141 and a rotatable column 142, and the outer wall of the column body 142 is provided with a guide groove 1420, which is a closed annular structure; the first end of the rod body 141 is connected to the adjusting member 13, and the second end of the rod body 141 extends into the guide groove 1420, and the second end of the rod body 141 is slidably connected to the guide groove 1420; the rotation of the column 142 can cause the rod body 141 to move back and forth, so that the rod body 141 drives the adjusting member 13 to move to the preset position.

[0038] like Figure 4 As shown, a driver 14 is used to achieve the movement and adjustment of the adjusting member 13 through a power-driven method. The driver includes a rotatable cylinder 142, for example, which can be driven by a motor. A guide groove 1420 on the outer wall of the cylinder 142 has a predetermined trajectory and profile. As the circumferential position of the guide groove 1420 along the outer wall of the cylinder 142 changes, the position of the guide groove 1420 along the axial direction of the cylinder 142 also changes. Thus, during the rotation of the cylinder 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 cylinder 142 under the action of the guide groove 1420. The adjusting member 13, which is connected to the first end of the rod 141, is also driven by the rod 141 to move, thereby controlling the opening and closing of the fluid channel or the flow area of the fluid in the fluid channel. As can be seen, the driver 14 of this embodiment, by providing the guide groove 1420 on the outer wall of the cylinder 142, converts the rotation of the cylinder 142 into the translation of the rod 141 and the adjusting member 13.

[0039] In this embodiment, the guide groove 1420 on the outer wall of the column 142 can be a closed annular structure. As the column 142 rotates unidirectionally, the second end of the rod 141 slidably connected to the guide groove 1420 can reciprocate along the axial direction of the column 142. In other embodiments, the guide groove 1420 on the outer wall of the column 142 can also be a non-closed arc structure. In this way, the second end of the rod 141 slidably connected to the guide groove 1420 can 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 that drives the rotation of the column 142 can be provided with a backstop. After the adjustment member 13 moves to the preset position, the motor is prevented from rotating in the opposite direction by mechanical locking or friction resistance, so that the adjustment member 13 can remain stably in the preset position. In some other embodiments, a check structure may also 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 is self-locking, so that the friction force 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 along the guide groove 1420, thereby allowing the adjusting member 13 to stay stably in the preset position.

[0040] The liquid supply device 10 provided in the embodiment of the present application includes: a first container 11, a second container 12, an adjusting member 13 and a driving member 14; the first container 11 is provided with a liquid inlet and a liquid outlet; the second container 12 is connected to the first container 11, and a fluid channel is provided between the second container 12 and the first container 11; the adjusting member 13 is movably provided in the fluid channel to adjust the fluid in the first container 11 to flow into the second container 12 through the fluid channel; the driving member 14 is used to drive the adjusting member 13 to move 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, which is a closed annular structure. The first end of the rod 141 is connected to the adjusting member 13, and 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. The column 142 rotates to cause the rod 141 to reciprocate, so that the rod 141 drives the adjusting member 13 to move to the preset position. The liquid supply device 10 uses the adjusting member 13 provided on the fluid passages of the first container 11 and the second container 12 to allow the fluid in the first container 11 to flow into the second container 12, thereby regulating the fluid storage volume in the first container 11, thereby facilitating the adjustment of the fluid usage.

[0041] In one embodiment of the present application, an inclined rod may be provided between the adjusting member 13 and the rod body 141 , one end of the inclined rod is connected to the adjusting member 13 , and the other end of the inclined rod is connected to the rod body 141 , thereby improving the supporting strength and reliability of the rod body 141 for the adjusting member 13 .

[0042] Optionally, in one embodiment of the present application, Figure 5 、 Figure 6 As shown, the adjusting member 13 further includes a slide groove 15. The adjusting member 13 is 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, allowing for rapid adjustment of the fluid passage area, thereby improving the response speed of the adjusting member 13. Furthermore, the provision of the slide groove 15 facilitates configuring a sealing structure for the adjusting member 13. For example, a sealing member 18 is provided on the wall of the slide groove 15 to enhance the sealing contact between the adjusting member 13 and the slide groove 15.

[0043] In this embodiment, the position and number of the 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-like structure. For example, the adjusting member 13 can be a single plate, or the adjusting member 13 can include multiple plates. For example, the adjusting member 13 can include a stacked front plate and a rear plate. Both 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 helps to improve the structural strength of the adjusting member 13 and facilitates the differentiated configuration of different structural parts of the adjusting member 13. For example, the front plate can be made of a wear-resistant, pressure-resistant, or corrosion-resistant material, and the rear plate can be made of a material with higher structural strength.

[0044] In order to improve the reliability and stability of the adjustment member 13 sliding along the chute 15, optionally, in one embodiment of the present application, at least two chute 15 are provided, and the two chute 15 are located on both sides of the fluid channel, and the two sides of the adjustment member 13 are slidably connected to the two chute 15. By providing two chute 15, both sides of the adjustment member 13 can be supported by the chute 15 and slide along the chute 15 at the same time, so that the adjustment member 13 has more stable and reliable force support during the sliding process, avoiding jamming. In addition, providing two chute 15 is also conducive to simultaneously providing sealing members 18 on the groove walls of the two chute 15 to ensure the sealing performance of the adjustment member 13 when it adjusts the fluid flow through the fluid channel.

[0045] Optionally, in one embodiment of the present application, Figure 6As shown, the second container 12 is provided with at least a first plate 161 and a second plate 162 on a side close to the first container 11, and a chute 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 a plate material, and the first plate 161 and the second plate 162 can be provided on the side close to the first container 11. In this way, a reserved space can be provided between the first plate 161 and the second plate 162 to form the chute 15. A sealing member 18 can also be further provided between the first plate 161 and the second plate 162. In this way, the first plate 161, the second plate 162 and the sealing member 18 enclose the chute 15.

[0046] In this embodiment, a first plate 161 and a second plate 162 can be provided on either side of the fluid channel, thereby forming a chute 15 on each side of the fluid channel. A notch can be provided in the sidewall of the first container 11 adjacent to the second container 12. A fluid channel can be formed along the notch in the sidewall of the first container 11, the second plate 162, and the first plate 161. Furthermore, a guide structure, such as a guide plate, can be provided along the fluid channel to facilitate the flow of fluid in the fluid channel.

[0047] Optionally, in one embodiment of the present application, Figure 6 、 Figure 7 As shown, a third plate body 163 is further provided on the side of the second plate body 162 facing away from the first plate body 161, and an elastic column 171 is provided between the third plate body 163 and the second plate body 162, and a tube body 172 is axially passed through the elastic column 171, and the length of the tube body 172 is less than the length of the elastic column 171; the second plate body 162 is provided with a first end connecting piece 173 connected to the first end of the tube body 172, and / or the third plate body 163 is provided with a second end connecting piece 174 connected to the second end of the tube body 172.

[0048] In this embodiment, Figure 7 、 Figure 8 As shown, an elastic column 171 is provided between the third plate 163 and the second plate 162 to achieve an elastically adjustable connection between the third plate 163 and the second plate 162. Specifically, as shown in FIG. Figure 7 、 Figure 9As shown, the elastic column 171 can be a hollow tubular structure made of rubber, so that the elastic column 171 can be penetrated by a tube body 172 along the axial direction, and the length of the tube body 172 along the axial direction is less than the length of the elastic column 171 along the axial direction. The first end of the tube body 172 and the second end of the tube body 172 can be provided with internal threads respectively, and a through hole can be opened at a corresponding position of the second plate body 162, and a first end connector 173 connected to the first end of the tube body 172 can be penetrated, for example, the first end connector 173 can be a bolt and threadedly connected to the first end of the tube body 172, a through hole is also opened at a corresponding position of the third plate body 163, and a second end connector 174 connected to the second end of the tube body 172 can be penetrated, for example, the second end connector 174 can also be The bolt is threadedly connected to the second end of the tube body 172. In this way, the relative distance between the second plate body 162 and the third plate body 163 can be changed by adjusting the threaded connection length of the first end connecting piece 173 and the first end of the tube body 172, and / or adjusting the threaded connection length of the second end connecting piece 174 and the second end of the tube body 172, so that the compression amount of the elastic column 171 between the second plate body 162 and the third plate body 163 changes, thereby adjusting the relative distance between the second plate body 162 and the first plate body 161, that is, adjusting the groove width of the slide groove 15, so that the adjusting piece 13 is adapted to the size of the slide groove 15, and the adjusting piece 13 can not only slide smoothly along the slide groove 15, but also form a good sealing effect with the slide groove 15.

[0049] In other embodiments, a through hole may be formed at a corresponding position on the second plate 162, through which a first end connector 173 connected to the first end of the tube 172 may be provided. For example, the first end connector 173 may be a bolt 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 length of the threaded connection between the first end connector 173 and the first end of the tube 172. A through hole may also be formed at a corresponding position on the third plate 163, through which a second end connector 174 connected to the second end of the tube 172 may be provided. For example, the second end connector 174 may be a bolt threadedly connected to the second end of the tube 172. 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 length of the threaded connection between the second end connector 174 and the second end of the tube 172.

[0050] In one embodiment of the present application, Figure 9As shown, the first end of elastic column 171 and the second end of elastic column 171 have a first outer diameter, and the portion between the first end of elastic column 171 and the second end of elastic column 171 has a second outer diameter, wherein the first outer diameter is greater than the second outer diameter. This design of elastic column 171 allows the first end of elastic column 171 and the second end of elastic column 171 to have a larger force-bearing contact area with second plate 162 and third plate 163, respectively, which helps to improve the stability of the support connection.

[0051] There can be multiple elastic columns 171 arranged between the third plate body 163 and the second plate body 162, for example more than two. The multiple elastic columns 171 located between the third plate body 163 and the second plate body 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 to avoid local jamming and improve the adjustment ability of the sliding connection performance and sealing performance between the adjustment member 13 and the slide groove 15.

[0052] Optionally, in one embodiment of the present application, Figure 6 As shown, the second plate body 162 is provided with a seal 18 on a side close to the first plate body 161; and / or the first plate body 161 is provided with a seal 18 on a side close to the second plate body 162. The seal 18 can be connected to the second plate body 162, and can also be connected to the first plate body 161. The seal 18 can be made of rubber, for example, the seal 18 can be a plate-shaped structure connected to the second plate body 162, so that a seal is formed between the adjustment member 13 and the second plate body 162. Alternatively, the seal 18 can be an L-shaped structure connected to the second plate body 162, so that a seal can be formed between the adjustment member 13 and the second plate body 162, and a seal can also be formed between the adjustment member 13 and the bottom of the slide groove 15.

[0053] In order to further improve the sliding flexibility of the adjusting member 13 in the sliding groove 15, optionally, in one embodiment of the present application, 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 is capable of rolling contact with the adjusting member 13. In this embodiment, the pin 1611 and the rolling element 1612 on the first plate 161 can be arranged according to the specific configuration of the adjusting member 13 and the chute 15. For example, the rolling element 1612 can be configured to roll with the side of the adjusting member 13 facing away from the second plate 162, or the rolling element 1612 can be configured to roll with the side of the adjusting member 13 facing the bottom of the chute 15. The number of pins 1611 and the corresponding rolling element 1612 sleeved on the first plate 161 can be multiple, for example, more than two. Multiple pins 1611 and the corresponding rolling element 1612 sleeved on each pin 1611 can be arranged along the length of the chute 15 to enable the adjusting member 13 to slide flexibly along the chute 15.

[0054] Optionally, in one embodiment of the present application, Figure 2 As shown, the bottom of the first container 11 is funnel-shaped; specifically, the first container 11 can be a metering hopper with a metering function, which can monitor parameters such as the quality or volume of the stored fluid. The funnel-shaped bottom is conducive to setting a liquid outlet to facilitate the discharge of the fluid from the first container 11.

[0055] Optionally, in one embodiment of the present application, the first container 11 is provided with a vent 110; Figure 2 As shown, the provision of the vent 110 is conducive to injecting fluid into the first container 11 or discharging fluid from the first container 11. For example, when injecting fluid into the first container 11, the gas in the first container 11 can be discharged through the vent 110. When discharging fluid 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 air pressure on the liquid surface in the first container 11 remains constant, avoiding the injection or discharge of fluid being affected by the change of the air pressure in the first container 11 during the process of injecting fluid into or discharging fluid into the first container 11.

[0056] Optionally, in one embodiment of the present application, the first container 11 is provided with a metering member 111 to detect the storage amount of the fluid in the first container 11; Figure 2 As shown, the measuring element 111 may be a pressure sensor provided at the support portion of the first container 11 , and the storage amount of the fluid in the first container 11 is calculated according to the pressure change at the support portion of the first container 11 .

[0057] Optionally, in one embodiment of the present application, Figure 1 、 Figure 2 、 Figure 3As shown, the liquid inlet portion of the first container 11 includes a liquid inlet 112 provided on the top of the first container 11, and a liquid inlet pipe 113 that can be communicated with the liquid inlet 112, and the liquid inlet pipe 113 is at least partially a hose; in this embodiment, the liquid inlet 112 can be opened on the top of the first container 11, and the liquid inlet pipe 113 can be suspended on 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 communicated with the liquid inlet 112, for example, the second end of the liquid inlet pipe 113 can be suspended above the liquid inlet 112, so that the second end of the liquid inlet pipe 113 can switch the position of the fluid supply. The fluid output by the response equipment, such as a water tank or a pool, can flow into the first container 11 from the second end of the liquid inlet pipe 113 through the liquid inlet 112 through the liquid supply path. For example, when the metering member 111 detects that the storage amount of the fluid in the first container 11 reaches a preset value, the second end of the liquid inlet pipe 113 can be moved so that the second end of the liquid inlet pipe 113 is switched from a position above the liquid inlet 112 to a reflux position. When the second end of the liquid inlet pipe 113 is switched to the reflux position, the fluid flowing out from the second end of the liquid inlet pipe 113 no longer flows into the liquid inlet 112 and the first container 11, but flows back to the fluid supply equipment through the return liquid path.

[0058] Furthermore, configuring the liquid inlet tube 113 as at least partially a flexible tube facilitates switching the second end of the liquid inlet tube 113, reduces the impact of fluid flow, and facilitates connection of the liquid inlet tube 113 to the liquid supply path. In some embodiments, the second end of the liquid inlet tube 113 can extend into the first container 11 to minimize the drop of fluid flowing from the second end of the liquid inlet tube 113 into the first container 11, thereby preventing an impact on the measurement accuracy of the metering element 111, such as a pressure sensor.

[0059] Optionally, in one embodiment of the present application, Figure 2 As shown, the liquid outlet of the first container 11 includes a liquid outlet 114 provided at the bottom of the first container 11, and a liquid outlet pipe 115 capable of communicating with the liquid outlet 114, and the liquid outlet pipe 115 is at least partially a hose; the liquid outlet 114 can be provided at the funnel-shaped bottom of the first container 11, and the liquid outlet pipe 115 is configured to be at least partially a hose, which is also beneficial to reducing the impact of the fluid and facilitating the connection of the liquid outlet pipe 115 with other pipelines.

[0060] Optionally, in one embodiment of the present application, Figure 2 As shown, a regulating valve 116 is provided at the liquid outlet of the first container 11. Specifically, the regulating valve 116 can be a butterfly valve, such as a pneumatic butterfly valve, which 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 conditions of the mixer.

[0061] Optionally, in one embodiment of the present application, Figure 2As shown, the second container 12 is provided with an outflow port 120; and / or the second container 12 is provided with an avoidance groove 121 along the moving direction of the regulating member 13. The outflow port 120 of the second container 12 can also be connected to the return liquid flow path, so that the fluid in the second container 12 can also flow back to the fluid supply device through the return liquid flow path. In the embodiment of the present application, Figure 5 As shown, the second container 12 is provided with an avoidance groove 121 along the moving direction of the adjusting member 13, which can form an avoidance space for the driving member 14, which is conducive to making full use of the spatial structure of the equipment and reducing the structural volume. For example, the rod body 141 of the driving member 14 can pass through the avoidance groove 121, so that the first end of the rod body 141 is connected to the adjusting member 13 and drives the adjusting member 13 to move.

[0062] Optionally, in one embodiment of the present application, Figure 1 、 Figure 2 As shown, it also includes a support base 191, the first container 11 is disposed on the support base 191, the support base 191 is further connected to a bracket 192, and the driving member 14 is disposed on the bracket 192. The support base 191 and the bracket 192 can be made of channel steel or the like, wherein the support base 191 can be a rectangular frame structure, the first container 11 can be inserted and fixed in the rectangular frame, the bottom of the bracket 192 is connected to the support base 191, the top of the bracket 192 can be connected to the top of the first container 11, and the driving member 14 can be fixedly suspended on the bracket 192.

[0063] In the process of using the above-mentioned liquid supply device 10 of the present application, the fluid in the fluid supply device, such as water, can enter from the first end of the liquid inlet pipe 113 configured for the first container 11 through the liquid supply flow path, and flow into the first container 11 from the second end of the liquid inlet pipe 113 through the liquid inlet port 112. When the metering member 111 detects that the storage amount of the fluid in the first container 11 reaches a preset value, the second end of the liquid inlet pipe 113 can be moved so that the second end of the liquid inlet pipe 113 is switched from the position above the liquid inlet port 112 to the reflux position. When the second end of the liquid inlet pipe 113 is switched to the reflux position, the fluid flowing out from the second end of the liquid inlet pipe 113 no longer flows out. The liquid does not flow into the liquid inlet 112 and the first container 11, but flows back to the fluid supply device through the return liquid path. In this way, the delivery pump of the liquid supply path for delivering fluid from the fluid supply device to the first container 11 is always open and in working state, avoiding the water hammer effect caused by frequent opening and closing, and simplifying the components of the liquid supply path. For example, the liquid supply device 10 of this embodiment can eliminate the slow-closing check valve, water hammer absorber, electric ball valve, metal hose, rubber shock absorber, pneumatic butterfly valve, etc. in the liquid supply path for supplying liquid to the first container 11 compared with the traditional liquid supply method, which is beneficial to reducing equipment costs and improving the working reliability and service life of the liquid supply path.

[0064] When the fluid in the first container 11, such as water, meets the quality or weight requirements, the regulating valve 116, such as a butterfly valve, provided at the bottom liquid outlet of the first container 11 can be opened, so that the fluid in the first container 11 can flow into the mixer. Since the mixer often requires a certain amount of time to mix a batch of materials such as fly ash, coal gangue, cement, water, etc. evenly, the liquid supply device 10 of the present application can be used to move and open the regulating member 13 provided for the fluid channel between the first container 11 and the second container 12, so that the excess fluid stored in the first container 11 can flow into the second container 12 through the fluid channel. The fluid flowing into the second container 12 can flow back to the fluid supply device from the outflow port 120 of the second container 12 through the return liquid flow path, so that the fluid in the second container 12 can be recycled. Through the above method, the mixer can work intermittently and repeatedly to achieve the purpose of constant liquid supply and uniform mixing.
