DETAILED DESCRIPTION

[0020] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0021] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0022] At present, in the process of preparing filling paste, in order to control the amount of liquid stored in the metering bucket, it is necessary to control the opening and closing of the regulating valve, such as the pneumatic butterfly valve, to switch the liquid supply route. The pneumatic butterfly valve is closed 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 produce an impact of more than 1.60Mpa, causing the pipeline and the pneumatic butterfly valve to instantly increase pressure, vibrate strongly, produce a water hammer effect, and easily damage the pneumatic butterfly valve and other components. In order to solve the above problems, such as 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 adjustment member 13 and a driving member 14 .

[0023] 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 the fluid has high environmental requirements 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 fluid to flow into the first container 11, and the liquid outlet is used for fluid in the first container 11 to flow out. Figure 2 , Figure 3As shown, the liquid inlet portion may include a liquid inlet port 112 opened on the first container 11 , or may include a pipeline or a pipe group such as a liquid inlet pipe 113 suspended above the first container 11 , so as to allow a single fluid or multiple fluids to flow into the first container 11 .

[0024] 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 amount in the first container 11 according to the actual production situation. 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 the volume of the first container 11 to reduce the equipment manufacturing cost or equipment volume, and the volume of the second container 12 can also be greater than or equal to the volume of the first container 11 to have a higher capacity to accommodate and adjust the fluid in the first container 11.

[0025] like Figure 2 As shown, the second container 12 can be arranged on one side of the first container 11 or at the bottom of the first container 11, so that 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 some other embodiments, the second container 12 can also be arranged at any position relative to the first container 11, and a power device is used to make the fluid in the first container 11 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 set on the second container 12 to make the fluid in the second container 12 flow to the target position.

[0026] The adjusting member 13 is movably disposed in the fluid channel to adjust 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 control the opening and closing of the fluid channel or the passing area of ​​the fluid in the fluid channel by moving, and can also control the opening and closing of the fluid channel or the passing area of ​​the fluid in the fluid channel by rotating, so as to adjust the fluid in the first container 11 to flow into the second container 12 through the fluid channel. For example, the adjusting member 13 can be moved to a closed position, so that the fluid in the first container 11 cannot flow into the second container 12 through the fluid channel; the adjusting member 13 can be moved to a fully open position, so that the fluid in the first container 11 can flow into the second container 12 through the fluid channel with the largest possible flow capacity; the adjusting member 13 can be moved to a preset open position, so that the fluid in the first container 11 can flow into the second container 12 through the fluid channel with a preset flow capacity; the fluid capacity here can be the speed or flow rate of the fluid. In addition, the adjusting member 13 can be adjusted manually, or by a power drive, or a monitoring device can be installed on site, and the adjusting member 13 can be adjusted by remote control according to the on-site working conditions photographed by the monitoring device.

[0027] In order to reduce the workload and improve the convenience and automation of adjusting the fluid dosage, a driving member 14 is configured in this embodiment, and the driving member 14 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 142 is provided with a guide groove 1420, and the guide groove 1420 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 make the rod body 141 move back and forth, so that the rod body 141 drives the adjusting member 13 to move to the preset position.

[0028] like Figure 4 As shown, the driving member 14 is used to realize the movement and adjustment of the adjusting member 13 by a power-driven method. The driving member has a rotatable column 142, for example, the column 142 can be driven to rotate by a motor, and the guide groove 1420 on the outer wall of the column 142 has a preset track and contour shape. As the circumferential position of the guide groove 1420 along the outer wall of the column 142 changes, the position of the guide groove 1420 along the axial direction of the column 142 also changes. In this way, during the rotation of the column 142, the second end of the rod 141 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, and the adjusting member 13 connected to the first end of the rod 141 will move under the drive of the rod 141, thereby controlling the opening and closing of the fluid channel or the passing area of ​​the fluid in the fluid channel. It can be seen that the driving member 14 of this embodiment, by setting the guide groove 1420 on the outer wall of the column 142, the rotation of the column 142 is converted into the translation of the rod 141 and the adjusting member 13.

[0029] In this embodiment, the guide groove 1420 on the outer wall of the column 142 can be a closed annular structure. With the unidirectional rotation of the column 142, 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 some other embodiments, the guide groove 1420 on the outer wall of the column 142 can also be a non-closed arc structure, so that 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 driving the column 142 to rotate can be provided with a backstop to prevent the motor from rotating in the opposite direction through mechanical locking or friction resistance after the adjusting member 13 moves to the preset position, so that the adjusting member 13 can stably stay at 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 stably stay in the preset position.

[0030] 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 arranged 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 to a preset position; the driving member 14 includes a rod body 141 and a rotatable column 142, the outer wall of the column 142 is provided with a guide groove 1420, and the guide groove 1420 is a closed annular structure; the first end of the rod body 141 is connected to the adjusting member 13, 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 column 142 rotates to enable the rod body 141 to reciprocate, so that the rod body 141 drives the adjusting member 13 to move to a preset position. The liquid supply device 10 uses the adjusting member 13 provided on the fluid passage of the first container 11 and the second container 12 to enable the fluid in the first container 11 to flow into the second container 12, so as to adjust the fluid storage amount in the first container 11, thereby facilitating the adjustment of the amount of fluid.

[0031] 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 .

[0032] Optionally, in one embodiment of the present application, Figure 5 , Figure 6 As shown, the adjusting member 13 further includes a slide groove 15, and the adjusting member 13 is a plate-shaped structure, and the adjusting member 13 is slidably connected to the slide groove 15. The plate-shaped adjusting member 13 slides along the slide groove 15, and can quickly adjust the passing area of ​​the fluid channel, which is beneficial to improving the response speed of the adjusting member 13. In addition, the setting of the slide groove 15 is also beneficial to configure a sealing structure for the adjusting member 13, for example, a sealing member 18 is set at the groove wall position of the slide groove 15, so as to improve the sealing contact ability between the adjusting member 13 and the slide groove 15.

[0033] In this embodiment, the position of the slide groove 15, the number of the slide grooves 15 and the sliding direction of the adjusting member 13 can be set according to specific circumstances. For example, a slide groove 15 can be set at the bottom of the fluid channel, and the adjusting member 13 can move left and right along the slide groove 15. The slide groove 15 can also be set at the side of the fluid channel, and the adjusting member 13 can move up and down along the slide groove 15. The adjusting member 13 is a plate-like structure. For example, the adjusting member 13 can be a single plate body, and the adjusting member 13 can also include multiple plates. For example, the adjusting member 13 can include a stacked front plate body and a rear plate body. Both sides of the front plate body can slide along the slide groove 15, one side of the rear plate body is connected to the front plate body, and the other side of the rear plate body can be connected to the rod body 141. It can be understood that the adjusting member 13 including the front plate body and the rear plate body is conducive to improving the structural strength of the adjusting member 13, and is conducive to differential configuration of different structural parts of the adjusting member 13. For example, the front plate body can be made of wear-resistant, pressure-resistant or corrosion-resistant materials, and the rear plate body can be made of materials with higher structural strength.

By providing two slide grooves 15, both sides of the adjustment member 13 can be supported by the slide grooves 15 at the same time and slide along the slide grooves 15, so that the adjustment member 13 can have a more stable and reliable force support during the sliding process to avoid jamming. In addition, by providing two slide grooves 15, it is also beneficial to simultaneously provide a sealing member 18 on the groove wall of the two slide grooves 15 to ensure the sealing performance of the adjustment member 13 when it realizes the adjustment effect on the fluid flowing through the fluid channel.

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 a side of the second container 12 close to the first container 11, so that a reserved space can be provided between the first plate 161 and the second plate 162 to form the slide groove 15, and a sealing member 18 can be further provided between the first plate 161 and the second plate 162, so that the first plate 161, the second plate 162 and the sealing member 18 surround the slide groove 15.

[0036] In this embodiment, a first plate 161 and a second plate 162 may be provided on both sides of the fluid channel, so as to form a chute 15 on both sides of the fluid channel.

The first end of the tube body 172 and the second end of the tube body 172 can be respectively provided with internal threads, 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 is threadedly connected to the first end of the tube body 172, and 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 is 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 between the first end connecting piece 173 and the first end of the tube body 172, and / or adjusting the threaded connection length between 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 adjustment piece 13 is adapted to the size of the slide groove 15, and the adjustment piece 13 can not only slide smoothly along the slide groove 15, but also form a good sealing effect with the slide groove 15.

[0039] In other embodiments, a through hole may be provided at a corresponding position of the second plate 162, and 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 and threadedly connected to the first end of the tube 172, and the third plate 163 may be fixedly connected to the second end of the tube 172, and the relative distance between the second plate 162 and the third plate 163 may be changed by adjusting the threaded connection length between the first end connector 173 and the first end of the tube 172.

[0044] 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.

[0045] 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 air 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 air vent 110, and when discharging fluid from the first container 11, the gas outside the first container 11 can enter the first container 11 through the air 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 due to the change of air pressure in the first container 11 during the process of injecting fluid into or discharging fluid into the first container 11.

[0047] 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 arranged at the top of the first container 11, and a liquid inlet pipe 113 that can be connected to 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 at the top of the first container 11, and the liquid inlet pipe 113 is 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, so that the second end of the liquid inlet pipe 113 can switch positions, and the fluid supply The fluid output by the corresponding 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 port 112 through the liquid supply flow 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 port 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 port 112 and the first container 11, but flows back to the fluid supply equipment through the return flow path.

[0048] In addition, the liquid inlet pipe 113 is configured to be at least partially a hose, which is convenient for switching the position of the second end of the liquid inlet pipe 113, and is also conducive to reducing the impact of the fluid, and is convenient for connecting the liquid inlet pipe 113 with the liquid supply flow path. In some embodiments, the second end of the liquid inlet pipe 113 can extend into the first container 11 to reduce the drop of the fluid flowing from the second end of the liquid inlet pipe 113 into the first container 11, so as to avoid affecting the measurement accuracy of the metering element 111, such as a pressure sensor.

[0049] 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 arranged at the bottom of the first container 11, and a liquid outlet pipe 115 that can be connected to the liquid outlet 114, and the liquid outlet pipe 115 is at least partially a hose; the liquid outlet 114 can be arranged 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 reduce the impact of the fluid and facilitate the connection of the liquid outlet pipe 115 with other pipelines.

[0050] Optionally, in one embodiment of the present application, Figure 2 As shown, the liquid outlet of the first container 11 is provided with a regulating valve 116. 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, and 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 situation of the mixer.

[0051] 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 adjusting member 13. The outflow port 120 of the second container 12 may also be connected to the return liquid flow path, so that the fluid in the second container 12 may also flow back to the fluid supply device through the return liquid flow path. 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 fully utilizing 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.

[0052] Optionally, in one embodiment of the present application, Figure 1 , Figure 2 As shown, it also includes a support seat 191, the first container 11 is arranged on the support seat 191, the support seat 191 is also connected to a bracket 192, and the driving member 14 is arranged on the bracket 192. The support seat 191 and the bracket 192 can be made of channel steel, etc., wherein the support seat 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 seat 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.

[0053] 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 flow path. In this way, the delivery pump of the liquid supply flow path for delivering fluid from the fluid supply device to the first container 11 is always turned on and in working state, so as to avoid the water hammer effect caused by frequent opening and closing, and simplify the components of the liquid supply flow 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 flow path for supplying liquid to the first container 11 compared with the traditional liquid supply method, which is beneficial to reduce equipment cost and improve the working reliability and service life of the liquid supply flow path.

[0054] 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 needs a certain amount of time to mix evenly during the process of mixing a batch of materials such as coal ash, coal gangue, cement, water, etc., 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.
