Detailed Implementation
[0021] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0022] 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.
[0023] In the preparation of filling slurry, fluids such as filling paste, brine, mortar, or water are supplied to a mixer. The mixer mixes the fluid with coal gangue, tailings, etc., to produce the filling slurry. However, during the preparation of fluids such as filling paste, the fluid's fluidity often causes disturbances, affecting the metering or measurement accuracy and impacting the stability of the fluid supply during production. To address these issues, such as... Figure 1 , Figure 2 As shown, an embodiment of this application provides a filling paste supply device 70, which may include: a liquid storage device 71 and a stirring device 72.
[0024] The liquid storage device 71 has a liquid storage chamber 710, and is further provided with a first liquid inlet 711 and a first liquid outlet 712, which are respectively connected to the liquid storage chamber 710. Within the liquid storage chamber 710, a flow-damping plate 713 is provided on the fluid channel from the first liquid inlet 711 to the first liquid outlet 712. In this embodiment, the liquid storage device 71 can be a container structure capable of storing fluid, such as a box, tank, or barrel, and can be made of metal or similar materials. The liquid storage device 71 forms a liquid storage chamber 710 for storing fluid. External fluid can flow into the liquid storage chamber 710 from the first liquid inlet 711 and flow out of the liquid storage chamber 710 from the first liquid outlet 712.
[0025] Within the liquid storage chamber 710, a fluid channel is formed from the first inlet 711 to the first outlet 712. A flow-retardant plate 713 is provided on this fluid channel, which can impede the fluid and generate a flow-retardant effect, consuming the fluctuation energy of the fluid. It can be understood that during the flow of the fluid from the first inlet 711 to the first outlet 712, the fluctuating state gradually becomes stable and the fluid pressure gradually stabilizes. This can reduce the influence of fluid pressure fluctuations on the fluid flowing out of the first outlet 712 and avoid fluid pulsation, thereby helping to improve the fluid outflow from the first outlet 712 as measured by a metering device such as a flow meter, or the liquid storage capacity of the liquid storage device 71 as measured by a gravity meter.
[0026] The stirring device 72 is provided with a stirring chamber 720 and a stirring element 721, with the stirring element 721 located at least partially inside the stirring chamber 720. The stirring device 72 is also provided with a second liquid inlet 722 and a second liquid outlet 723, which are respectively connected to the stirring chamber 720. The second liquid inlet 722 is connected to the first liquid outlet 712. The stirring element 721 is used to stir the fluid flowing from the storage chamber 710 into the stirring chamber 720.
[0027] In this embodiment, the stirring device 72 can also adopt a structure such as a box, tank, or barrel, and be made of metal materials. The stirring device 72 forms a stirring chamber 720 and is provided with a stirring element 721 to stir the fluid in the stirring chamber 720. The first liquid outlet 712 and the second liquid inlet 722 can be connected by a pipe. In this way, the metering device of the liquid storage device 71 can be used to discharge a set amount of fluid from the first liquid outlet 712 of the liquid storage device 71 and flow into the stirring chamber 720 from the second liquid inlet 722 of the stirring device 72. The stirring element 721 stirs the fluid in the stirring chamber 720 evenly, avoiding fluid sedimentation or significant changes in performance, so as to supply fluid to liquid-using equipment such as a mixer at any time.
[0028] The mixing component 721 can be configured with a corresponding mixing structure according to the characteristics of the material. For example, the mixing component 721 can adopt a frame type, ribbon type, anchor type, turbine type, blade type, spring type and other structural forms. When making a specific selection, the appropriate mixing structure can be selected according to the actual working conditions such as material characteristics and process requirements.
[0029] The filling paste supply device 70 provided in the embodiments of this application includes: a liquid storage device 71 and a stirring device 72. The liquid storage device 71 has a liquid storage chamber 710, and the liquid storage device 71 is also provided with a first liquid inlet 711 and a first liquid outlet 712, which are respectively connected to the liquid storage chamber 710. A flow buffer 7 is provided on the fluid channel from the first liquid inlet 711 to the first liquid outlet 712 within the liquid storage chamber 710. 13; The stirring device 72 is provided with a stirring element 721 and a stirring chamber 720, with the stirring element 721 at least partially located within the stirring chamber 720; the stirring device 72 is also provided with a second liquid inlet 722 and a second liquid outlet 723, which are respectively connected to the stirring chamber 720, and the second liquid inlet 722 is connected to the first liquid outlet 712. The stirring element 721 is used to stir the fluid flowing from the storage chamber 710 into the stirring chamber 720. The flow-retardant plate 713 in the storage chamber 710 of the filling paste supply device 70 can create a flow-retardant effect on the fluid flowing from the first liquid inlet 711 to the first liquid outlet 712, blocking fluid fluctuations and ensuring the metering accuracy of the fluid flowing out of the first liquid outlet 712, thereby effectively improving the stability of the fluid supply.
[0030] Optionally, in one embodiment of this application, there are multiple flow-retarding plates 713, and the flow-retarding plates 713 include at least a first flow-retarding plate 713A and a second flow-retarding plate 713B. The first flow-retarding plate 713A and the second flow-retarding plate 713B are arranged sequentially along the fluid channel, and the first flow-retarding plate 713A and the second flow-retarding plate 713B protrude from the first inner wall of the liquid storage cavity 710.
[0031] The first inner wall can be the side wall, bottom wall, or top wall of the liquid storage cavity 710. For example, in this embodiment, the first inner wall can be the bottom wall of the liquid storage cavity 710. The first flow-slowing plate 713A and the second flow-slowing plate 713B are respectively arranged sequentially along the fluid channel on the bottom wall of the liquid storage cavity 710 to create a flow-slowing effect on the fluid. In some other embodiments, more flow-slowing plates 713 can be provided. It can be understood that multiple flow-slowing plates 713 further enhance the flow-slowing effect on the fluid, enabling the fluid to recover from a fluctuating state to a stable state more quickly.
[0032] Each flow-damping plate 713, such as the first flow-damping plate 713A and the second flow-damping plate 713B, can have its surface perpendicular to the direction of the fluid channel or perpendicular to the direction of fluid flow from the first inlet 711 to the first outlet 712, so as to create maximum obstruction effect on the fluid flowing from the first inlet 711 to the first outlet 712. In other embodiments, the surface of each flow-damping plate 713 can also have a preset angle with the direction of the fluid channel.
[0033] Optionally, in one embodiment of this application, the flow-retarding plate 713 includes at least a first flow-retarding plate 713A and a third flow-retarding plate 713C. The first flow-retarding plate 713A and the third flow-retarding plate 713C are arranged sequentially along the fluid channel, and the first flow-retarding plate 713A protrudes from the first inner wall of the liquid storage cavity 710, and the third flow-retarding plate 713C protrudes from the second inner wall of the liquid storage cavity 710.
[0034] The first inner wall and the second inner wall are different inner walls of the liquid storage cavity 710. For example, in this embodiment, the first inner wall can be the bottom wall of the liquid storage cavity 710, and the first flow-slowing plate 713A is disposed on the bottom wall of the liquid storage cavity 710. The second inner wall can be the top wall of the liquid storage cavity 710, and the third flow-slowing plate 713C is disposed on the top wall of the liquid storage cavity 710. The first flow-slowing plate 713A and the third flow-slowing plate 713C are arranged sequentially along the fluid channel to create a flow-slowing effect on the fluid. In other embodiments, more flow-slowing plates 713 can be provided. For example, the first flow-slowing plate 713A and the second flow-slowing plate 713B can be arranged sequentially on the bottom wall of the liquid storage cavity 710 along the fluid channel, and the third flow-slowing plate 713C and the fourth flow-slowing plate 713D can be arranged sequentially on the top wall of the liquid storage cavity 710 along the fluid channel. It can be understood that multiple flow-slowing plates 713 further enhance the flow-slowing effect on the fluid, enabling the fluid to recover from a fluctuating state to a stable state more quickly.
[0035] Furthermore, the surface of each flow-damping plate 713, such as the first flow-damping plate 713A and the third flow-damping plate 713C, can be perpendicular to the direction of the fluid channel or perpendicular to the direction of fluid flow from the first inlet 711 to the first outlet 712, so as to create maximum obstruction effect on the fluid flowing from the first inlet 711 to the first outlet 712. In other embodiments, the surface of each flow-damping plate 713 can also have a preset angle with the direction of the fluid channel.
[0036] Optionally, in one embodiment of this application, the first inner wall and the second inner wall are located on opposite sides of the liquid storage cavity 710; or the first inner wall is the bottom wall of the liquid storage cavity 710, and the second inner wall is the top wall of the liquid storage cavity 710. It can be understood that the first flow-slowing plate 713A and the third flow-slowing plate 713C are respectively disposed on opposite sides of the liquid storage cavity 710, which is beneficial to form a flow-slowing effect on the fluid on both sides respectively.
[0037] For example, in this embodiment, the first inner wall can be the bottom wall of the liquid storage cavity 710, the first flow-retarding plate 713A is disposed on the bottom wall of the liquid storage cavity 710, the second inner wall can be the top wall of the liquid storage cavity 710, and the third flow-retarding plate 713C is disposed on the top wall of the liquid storage cavity 710. The first flow-retarding plate 713A and the third flow-retarding plate 713C are arranged sequentially along the fluid channel. In this way, the first flow-retarding plate 713A can impede the lower part of the fluid, and the second flow-retarding plate 713B can impede the upper part of the fluid, thereby creating a flow-retarding effect on both sides of the fluid, resulting in a better flow-retarding effect. In other embodiments, the first inner wall and the second inner wall can also be two opposite side walls of the liquid storage cavity 710.
[0038] Optionally, in one embodiment of this application, the first inlet 711 is located at the upper part of the storage chamber 710, and the first outlet 712 is located at the lower part of the storage chamber 710; and / or the second inlet 722 is located at the upper part of the stirring chamber 720, and the second outlet 723 is located at the lower part of the stirring chamber 720. It is understood that this arrangement of the inlet and outlet facilitates the use of the fluid's own weight, allowing the fluid to flow more smoothly into and out of the storage chamber 710 or the stirring chamber 720. For example, the storage device 71 can be mounted on a support frame on a horizontal surface, and the stirring device 72 can be mounted on the horizontal surface. The height of the first outlet 712 can be set to be greater than the height of the second inlet 722 to fully utilize the fluid's own weight and facilitate smooth fluid transport. Furthermore, a pumping device can be provided between the first outlet 712 and the second inlet 722 to more quickly transport fluid from the storage chamber 710 to the stirring chamber 720 using power.
[0039] Optionally, in one embodiment of this application, the upper part of the liquid storage device 71 is provided with a cover plate 714, the cover plate 714 is provided with a first liquid inlet 711, and the liquid storage device 71 is also provided with a liquid inlet pipe 715, the liquid inlet pipe 715 extending at least partially from the first liquid inlet 711 into the liquid storage chamber 710.
[0040] The cover plate 714 of the liquid storage device 71 provides protection for the liquid storage chamber 710, preventing foreign objects from entering the liquid storage chamber 710 and affecting the fluid. Especially in harsh engineering environments, the cover plate 714 can improve the quality of fluid supply and protect it from external environmental influences. The inlet pipe 715 can be inserted into the liquid storage chamber 710 from the first inlet port 711 to ensure that the fluid is protected from external contamination during its delivery to the liquid storage chamber 710.
[0041] Optionally, in one embodiment of this application, the cover plate 714 of the liquid storage device 71 is further provided with an exhaust port 716, which is connected to the liquid storage chamber 710, and an exhaust pipe 717 is connected to the exhaust port 716. It can be understood that the exhaust port 716 and the exhaust pipe 717 on the cover plate 714 can prevent gas pressure fluctuations in the liquid storage chamber 710. For example, as fluid flows from the first inlet 711 into the storage chamber 710, the volume of liquid stored in the storage chamber 710 gradually increases, while the volume that can hold gas gradually decreases. Without an vent 716, the gas in the storage chamber 710 would be compressed, causing the gas pressure to rise, which would affect the pressure of the fluid flowing out from the first outlet. Conversely, as fluid flows out of the storage chamber 710 from the first outlet 712, the volume of liquid stored in the storage chamber 710 gradually decreases, while the volume that can hold gas gradually increases. Without an vent 716, the gas pressure in the storage chamber 710 would decrease, similarly affecting the pressure of the fluid flowing out from the first outlet, thus impacting fluid delivery or metering. Therefore, this embodiment, by providing an vent 716 and an vent pipe 717, helps improve the stability of fluid delivery and the accuracy of fluid metering.
[0042] Optionally, in one embodiment of this application, the stirring element 721 includes a rotating shaft 7211 and an impeller 7212. The rotating shaft 7211 extends into the stirring chamber 720, and the impeller 7212 is sleeved on the rotating shaft 7211. The rotating shaft 7211 can rotate under the drive of the power device to drive the impeller 7212 to rotate and stir.
[0043] In this embodiment, the rotating shaft 7211 can rotate under the drive of a power device such as an electric motor, driving the impeller 7212 to rotate and stir. The impeller 7212 can adopt a stirring paddle structure, for example, the impeller 7212 can be a blade-type stirring paddle or an anchor-type stirring paddle, etc. Multiple impellers 7212 can be arranged along the axial direction of the rotating shaft 7211 to ensure that the fluid in different parts of the stirring chamber 720 can be fully stirred, thereby improving the consistency of fluid stirring.
[0044] Optionally, in one embodiment of this application, a transfer pump 73 is further included. The transfer pump 73 is connected to the second liquid outlet 723 to pump the fluid in the stirring chamber 720 outward. The transfer pump 73 may specifically be a slurry pump. The slurry pump increases the energy of the solid-liquid mixture by means of the centrifugal force of the rotating impeller 7212, and can transport mixtures containing solid particles of slag and water, etc.
[0045] Optionally, in one embodiment of this application, a spare container is also provided near the liquid storage device 71 and the stirring device 72. The height of the liquid inlet of the spare container is lower than the bottom height of the liquid storage chamber 710, and the height of the liquid inlet of the spare container is lower than the bottom height of the stirring chamber 720.
[0046] A backup container can be used for safety backup. The height of the liquid inlet of the backup container is lower than the bottom height of the liquid storage chamber 710 and the bottom height of the stirring chamber 720. For example, the liquid storage device 71 and the stirring device 72 can be set above the horizontal plane, while the backup container can be set below the horizontal plane. In this way, when the liquid storage device 71 or the stirring device 72 malfunctions and the fluid in the liquid storage chamber 710 or the stirring chamber 720 flows outward, the outflowing fluid can be guided into the backup container, thereby avoiding any impact on the working environment. The backup container can be made of metal or masonry materials and is located near the liquid storage device 71 and the stirring device 72 to facilitate the timely transfer of fluid discharged from the liquid storage device 71 or the stirring device 72 into the backup container.
