Description

Technical Field

[0001] This invention belongs to the technical field of stirring devices, and particularly relates to a spiral-driven, self-balancing, anti-segregation filling device. Background Technology

[0002] Pipeline transportation plays a crucial role in mine backfilling due to its economic, environmental, and highly automated nature. It is widely used for long-distance transportation of high-concentration tailings, thereby reducing solid waste emissions and ground subsidence. However, during the transportation of long-distance (>1 km), high-concentration, multi-stage batched slurries, coarse and fine particles are prone to sedimentation and stratification, resulting in an imbalance in rheological properties. This leads to uneven velocity distribution across the pipeline cross-section, triggering an arching-collapse cycle and ultimately causing pipeline blockage. Summary of the Invention

The spiral mixing section includes a spiral guide plate, which extends spirally within the spiral mixing section. The rotary drive mechanism section includes a motor; The inclination angle of the spiral guide plate is greater than a preset angle, so that the sum of the frictional torques that hinder the rotation of the spiral mixing section is less than the driving torque transmitted to the spiral mixing section by the slurry through the spiral guide plate. The motor is used to periodically apply driving torque to the spiral mixing section, so that the spiral mixing section changes from angular velocity... Increase to .

[0008] In some implementations, it also includes: A rotary sealing structure is fitted at the junction of the spiral mixing section and the rotary drive mechanism section.

[0009] In some implementations, it also includes: The intelligent monitoring system is installed on the pipes before and after the spiral mixing section to collect the flow data of the slurry in real time and analyze the particle distribution and sedimentation of the slurry.

[0010] In some embodiments, the intelligent monitoring system includes: Flow sensing components are used to collect pressure and concentration data of the slurry; The edge computing module, connected to the flow sensing component, is used to process flow data and determine the conveying status of the slurry.

[0011] In some implementations, it also includes: The adaptive control component, connected to the intelligent monitoring system, is used to adjust the pumping rate of the slurry or trigger emergency cleaning operations based on the slurry flow analysis results, thereby maintaining stable pipeline delivery.

[0012] In some embodiments, the device further includes: A quick-connect interface is located at the end of the rotary drive mechanism section away from the spiral mixing section, and is used to enable quick assembly and disassembly with the slurry conveying pipeline.

[0013] This application provides a spiral-driven, self-balancing, anti-segregation filling device, comprising: The spiral mixing section is used to achieve the tumbling and mixing of the slurry, and can convert the kinetic energy and gravitational potential energy of the slurry into its own rotation; the spiral mixing section is used to achieve the tumbling and mixing of the slurry, and can convert the kinetic energy and gravitational potential energy of the slurry into its own rotation.

The motor is used to periodically apply driving torque to the spiral mixing section, so that the spiral mixing section changes from angular velocity Increase to .

[0014] The slurry is guided along a spiral trajectory by spiral guide vanes, causing it to undergo centrifugal motion and continuous tumbling to disrupt the settling tendency of solid particles.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] In some implementations, refer to Figure 1 and Figure 2 A self-balancing anti-segregation filling device for spiral-driven mud-blowing, comprising: The spiral mixing section 10 is used to realize the tumbling and mixing of the slurry and can convert the kinetic energy and potential energy of the slurry into its own rotation. The spiral mixing section 10 includes a spiral guide plate 12, which extends spirally in the spiral mixing section 10. Rotary drive mechanism section 20, including a motor; The inclination angle of the spiral guide plate 12 is greater than the preset angle, so that the sum of the frictional torques that hinder the rotation of the rotary drive mechanism section 20 is less than the driving torque of the slurry transmitted to the spiral mixing section 10 through the spiral guide plate 12. The motor is used to periodically apply driving torque to the spiral mixing section 10, so that the spiral mixing section 10 moves from a constant angular velocity. Increase to .

[0027] Specifically, in traditional filling devices, when conveying slurry, the density of solid particles is greater than that of liquid, leading to segregation phenomena such as particle settling and liquid floating, resulting in uneven strength of the filling body and affecting project quality. Conventional devices rely on a motor continuously driving the screw to agitate the slurry and prevent segregation. On the one hand, the motor needs to run continuously, resulting in high energy consumption; on the other hand, the slurry agitation depends entirely on the motor, which has a large load and wears out quickly. This application uses a screw structure to forcibly turn the mixed slurry, disrupting the particle settling tendency. Combined with the characteristic of using the slurry's own energy to convert into the rotational power of the device, the screw mixing section 10 is self-rotating. At the same time, combined with the periodic disturbance of the motor, efficient agitation and mixing of the slurry is ensured under low energy consumption, ensuring the uniformity of solid-liquid mixing, improving the overall performance of the filling body, and avoiding pipe blockage caused by segregation during long-distance slurry transportation.

[0028] The spiral mixing section 10 includes spiral guide vanes 12 spirally distributed along the axis of the inner tube of the spiral mixing section 10. After the slurry enters the tube, it will move along the spiral trajectory of the spiral guide vanes 12. During the conveying process, the slurry will be guided by the guide vanes to make centrifugal motion and will continuously tumble along the spiral path of the spiral guide vanes 12, breaking the sedimentation trend of solid particles and keeping the solid and liquid components in a uniform mixing state to avoid segregation.

[0029] The preset angle threshold of the spiral guide vane 12 is calculated based on the mechanical equilibrium condition that the slurry transmission torque is greater than or equal to the frictional resistance torque. When the inclination angle of the spiral guide vane 12 exceeds the preset value, the slurry's own kinetic and potential energy is transferred to the spiral mixing section 10 pipe body through the guide vane as it moves along the guide vane, forming the driving torque that drives the pipe body to rotate.

[0030] For example, a calculation model for the torque transmitted by the slurry is established. When the slurry moves along the spiral guide vane 12, its kinetic and potential energy is converted into a driving torque on the tube body. This torque is directly related to the slurry density, flow velocity, and guide vane inclination angle, similar to the physical model of inclined channel flow in fluid mechanics.

[0031] Calculate the total frictional resistance torque. The resistance torque mainly comes from two parts: one is the friction between the slurry and the inner wall of the pipe, and the other is the bearing friction during the rotation of the spiral section. Both of these resistances can be directly calculated using parameters such as the material friction coefficient, contact area, and bearing type.

[0032] Solve for the inclination angle by solving a series of equations. Transform the inequality that the slurry transmission torque is greater than or equal to the frictional resistance torque into a mathematical equation containing the inclination angle. Substitute the known parameters to find the range of inclination angles that meet the conditions.

[0033] The driving torque needs to meet the total frictional torque of the rotary drive mechanism section 20. This means that under normal slurry concentration and flow rate, the device does not need a motor to drive it continuously. It can drive the spiral mixing section 10 to rotate by the energy of the slurry itself, thereby achieving self-driven operation and reducing motor power loss.

[0034] Based on this, the rotary drive mechanism section 20 contains a motor. Its main design purpose is to break the force balance state of the rotary drive mechanism section 20 through periodic dynamic disturbance, so as to apply tangential stirring force to the uniformly rotating slurry therein. This is achieved by monitoring the uniform rotational angular velocity of the spiral mixing section 10 under the force balance state. Once it is determined that a uniform equilibrium state has been reached, the motor outputs additional torque to the spiral mixing section 10, disrupting the force balance of the spiral mixing section 10 and causing the angular velocity of the spiral mixing section 10 to change from... Increase to angular velocity It can be greater than angular velocity Any value of ω, thereby causing the spiral guide vane 12 to accelerate in a stable state where the slurry and the spiral guide vane 12 are relatively stationary, thus actively stirring the slurry; when the angular velocity of the spiral mixing section 10 reaches ω, the slurry is actively stirred. Then, the motor stops, causing the angular velocity of the spiral mixing section 10 to decrease from... Slowly recover to steady-state angular velocity During this period, the spiral mixing section 10, because it cannot reach a steady state, will generate reverse acceleration, which will also actively agitate the slurry, thus forming two active agitation stages in this process, until the angular velocity of the spiral mixing section 10 drops back to a steady state. .

[0035] The motor starting condition is set to the angular velocity of the spiral mixing section 10 reaching a steady state. This can save motor energy to the greatest extent because the motor does not need to exert any effort except to increase angular velocity during the process. Accelerate to The other torques of _2 allow this torque to be very small, but this also means that the spiral mixing section 10 must have the ability to rotate the pipe body of the spiral mixing section 10 using only the energy of the slurry itself; otherwise... Setting this would be meaningless. Steady-state angular velocity The core characteristic is that the slurry driving torque and total friction torque of the spiral mixing section 10 are completely balanced at this point. In this state, the pipe body can maintain the rotational speed without additional external force, and the motor does not need to bear the torque cost of maintaining the operation of the spiral mixing section 10. If the spiral mixing section 10 does not have the above capabilities, then as soon as the motor stops, the spiral mixing section 10 will lose its angular velocity indefinitely until it stops. All the kinetic energy lost during this process must be made up by the active drive of the motor, which does not save energy. At the same time, if the motor is started to supplement power during the continuous deceleration of the spiral mixing section 10, the motor will need to provide torque to reverse the acceleration at that moment, which is usually twice that of direct acceleration from a constant speed, thus aggravating the mechanical fatigue of the motor. Therefore, the method of periodically providing torque is also difficult to implement.

[0036] This application provides a spiral-driven, self-balancing, anti-segregation filling device, comprising: The spiral mixing section 10 is used to realize the tumbling and mixing of the slurry, and can convert the kinetic energy and gravitational potential energy of the slurry into its own rotation; the spiral mixing section 10 is used to realize the tumbling and mixing of the slurry, and can convert the kinetic energy and gravitational potential energy of the slurry into its own rotation. The spiral mixing section 10 includes a spiral guide plate 12, which extends spirally in the spiral mixing section 10. Rotary drive mechanism section 20, including a motor; The inclination angle of the spiral guide plate 12 is greater than the preset angle, so that the sum of the frictional torques that hinder the spiral mixing section 10 from rotating is less than the driving torque transmitted to the spiral mixing section 10 by the slurry through the spiral guide plate 12. The motor is used to periodically apply driving torque to the spiral mixing section 10, so that the spiral mixing section 10 changes from angular velocity Increase to .

[0037] The spiral guide plate 12 guides the slurry along a spiral trajectory, causing the slurry to undergo centrifugal motion and continuous tumbling to disrupt the settling tendency of solid particles. At the same time, the kinetic energy and gravitational potential energy of the slurry itself are converted into the rotational power of the spiral mixing section 10 to achieve self-drive; and in conjunction with the motor, a steady-state angular velocity is achieved in the mixing section. At that time, a periodic torque is applied, causing its angular velocity to increase to After stopping, two active stirring processes occur during the acceleration and deceleration of the spiral mixing section 10. This achieves efficient and uniform mixing of slurry with low energy consumption, improves the overall performance of the filling body, avoids pipe blockage during long-distance slurry transportation, and reduces motor power loss and mechanical fatigue. It solves the technical problems of uneven filling body strength caused by slurry segregation, high energy consumption and rapid wear of motor during continuous full-load drive, and easy pipe blockage during long-distance slurry transportation in traditional filling devices.

[0038] In some implementations, refer to Figure 1 and Figure 2 The spiral mixing section 10 includes: Main spiral tube body 11; The kinetic energy conversion device inside the tube is installed inside the main spiral tube 11 to convert the kinetic energy and potential energy of the slurry passing through the main spiral tube 11 into the rotation of the main spiral tube 11 and to tumble and mix the slurry.

[0039] Specifically, the main spiral tube 11 is a hollow tubular component that constrains the slurry flow path and can rotate relative to the slurry under the drive of the kinetic energy conversion device inside the tube. For example, the main spiral tube 11 is integrally formed from high-strength wear-resistant cast steel, and sealed rotary bearings are provided at both ends of the tube. The inner wall of the main spiral tube 11 is rigidly connected to the kinetic energy conversion device inside the tube. When the rotational torque generated by the kinetic energy conversion device inside the tube is transmitted to the main spiral tube 11, the main spiral tube 11 rotates synchronously as a whole.

[0040] The in-pipe kinetic energy conversion device is the actuator for slurry energy conversion and passive mixing. Its main function is to convert the slurry energy into its own rotational tendency and that of the main helical tube 11. It can also be understood that the in-pipe kinetic energy conversion device and the main helical tube 11 are integrally formed, and their movement tendencies influence each other. For example, the in-pipe kinetic energy conversion device includes an impeller assembly. The curved blades of the impeller assembly are fixed to the main helical tube 11. Two to three sets of impellers are axially spaced along the central axis of the main helical tube 11, each set containing four curved blades with an inwardly concave arc shape. When the slurry flows in from the feed end, the slurry impacts the curved blades, driving the impeller assembly to rotate. Simultaneously, the inwardly concave arc-shaped blades support a portion of the slurry and move it upward along the curved trajectory of the blade surface, turning the bottom high-density aggregate to the surface for thorough mixing with the slurry, thereby preventing segregation.

[0041] In some implementations, refer to Figure 2 The kinetic energy conversion device inside the pipe includes: The spiral guide plate 12 extends spirally inside the main spiral tube body 11 to guide the medium flowing through the pipe body along the spiral trajectory and absorb the kinetic energy and gravitational potential energy of the medium.

[0042] Specifically, the spiral guide vane 12 extends continuously in a spiral shape inside the main spiral tube 11 and is integrally formed with it. After the slurry enters the tube, it is blocked and guided by the spiral guide vane 12 and forced to flow along the spiral trajectory of the guide vane. When the slurry flows along the spiral trajectory, it will impact the arc-shaped convex surface of the guide vane and transfer its own kinetic energy to the guide vane. At the same time, the gravitational potential energy of the slurry itself (usually due to the height difference between the ground slurry preparation station and the underground mine) will be converted into the rotational driving force of the guide vane through the squeezing action of the slurry on the guide vane. Thus, the rotational torque is transmitted to the main spiral tube 11 through the driving force of the spiral guide vane 12, driving the tube and the guide vane to rotate synchronously. In addition, the spiral trajectory prolongs the residence time of the slurry in the tube and also provides conditions for thorough mixing.

[0043] In some implementations, refer to Figure 1 The rotary drive mechanism segment 20 includes: Fixed pipe 21 is rotatably connected to the pipe body in the spiral mixing section 10, and fixed pipe 21 itself is fixed. Drive unit 22, used to provide active driving force; The gear transmission mechanism is installed on the pipe body in the spiral mixing section 10 to receive the driving force provided by the drive device 22 and convert it into the rotation of the pipe body.

[0044] Specifically, the fixed pipe 21 is a short pipe fixed in the slurry transport route and does not rotate. One side of the fixed pipe 21 is connected to the slurry input end, which is usually the end of a long-distance slurry transport pipe; the other side is rotatably connected to the main spiral pipe body 11 through a sealed bearing, that is, the main spiral pipe body 11 is rotatably connected to the slurry transport route through the fixed pipe 21.

[0045] The drive device 22 is used to provide active driving force to introduce disturbance force into the rotational tendency of the pipe (i.e., the main helical pipe 11) in the helical mixing section 10, thereby superimposing radial or circumferential motion in the slurry to form a compound motion. For example, the drive device 22 includes a low-power permanent magnet servo motor and a motor bracket mounted on the outer wall of the fixed pipe 21. The motor bracket adopts an angle steel structure, with one end fixed to the outer wall of the fixed pipe 21 by bolts, and the other end rigidly connected to the permanent magnet servo motor.

[0046] The gear transmission mechanism is used to receive the driving force provided by the drive device 22 and convert it into the rotation of the tube body. For example, the gear transmission mechanism consists of a driving gear, a transition gear, and a driven gear ring. The driving gear is a spur gear, which is fixed to the output shaft of the gearbox of the drive device 22 by a key connection and rotates synchronously with the motor. The transition gear is mounted on the extension bracket on the outer wall of the fixed tube 21 through a bearing seat, thereby changing the direction of power transmission, allowing the motor to be arranged laterally to avoid the slurry conveying path, and further reducing the speed to match the low-speed rotation requirements of the main spiral tube body 11. The driven gear ring is an internal gear ring structure. The inner ring is fixed to the outer wall of the main spiral tube body 11 by bolts. By meshing with the transition gear, it transmits the power of the drive device 22 to the main spiral tube body 11, directly driving the tube body to rotate, thereby realizing the disturbance of the internal slurry by the motor output.

[0047] In some implementations, refer to Figure 1 The gear transmission mechanism includes: The output gear 231 is located at the output end of the drive device 22; The input gear 232 is composed of annular teeth protruding outward from the outer surface of the tube body in the spiral mixing section 10, and the input gear 232 meshes with the output gear 231.

[0048] Specifically, the output gear 231 is the connecting unit between the drive device 22 and the gear transmission mechanism, and it is rigidly connected to the output end of the drive device. The input gear 232 is composed of annular teeth protruding directly outward from the outer surface of the tube body (i.e., the main spiral tube body 11) of the spiral mixing section 10. It is the receiving end of power transmission. It transmits power to the output gear 231 through external meshing. External meshing does not require additional space inside the tube body or the inner side of the fixed tube 21. Power connection can be completed simply by the transverse arrangement of the output gear 231 at the drive end and the transverse meshing of the input gear 232 at the tube body end. Compared with internal meshing or planetary meshing structures, it is simpler and will not interfere with the sealed bearing of the fixed tube 21 or the rotation path of the main spiral tube body 11.

[0049] In some implementations, refer to Figure 1 This device also includes: A rotary sealing structure is fitted at the junction of the spiral mixing section 10 and the rotary drive mechanism section 20.

[0050] A rotary sealing structure is fitted at the junction of the spiral mixing section 10 (main spiral tube 11) and the rotary drive mechanism section 20 (fixed tube 21) to solve the sealing problem of high-pressure slurry under dynamic rotation conditions. For example, the rotary sealing structure includes a main sealing component, a secondary sealing component, and a support base. The main sealing component adopts a U-shaped sealing ring with its lip facing the slurry side inside the tube. The sealing ring is fixed by a stainless steel pre-tightening spring, and the pre-tightening force is adaptively adjusted according to the slurry pressure to ensure that the lip is always tightly pressed against the outer sealing surface of the main spiral tube 11.

[0051] One end of the support is rigidly connected to the end face of the fixed pipe 21 by bolts, and the other end has a sealing component mounting groove. The secondary sealing component consists of an O-ring and a metal retainer ring. The O-ring is embedded in the annular groove of the rigid support, and the metal retainer ring is tightly attached to the outside of the O-ring. This not only restricts the axial deformation of the O-ring caused by the rotation of the main spiral tube 11, but also blocks the trace amount of slurry seeping from the main seal, thus forming a secondary seal.

[0052] In some implementations, refer to Figure 1 This device also includes: The intelligent monitoring system is installed on the pipes before and after the spiral mixing section 10 to collect the flow data of the slurry in real time and analyze the particle distribution and sedimentation of the slurry.

[0053] For example, an intelligent monitoring system includes: Flow sensing components are used to collect pressure and concentration data of the slurry; The edge computing module, connected to the flow sensing component, is used to process flow data and determine the conveying status of the slurry.

[0054] Specifically, the flow sensing components include a pressure sensor and a slurry concentration sensor. The pressure sensor is used to collect the pressure difference before and after the spiral section to determine whether particle deposition exists inside the pipe. For example, a diffused silicon pressure sensor is used, which is installed on the side wall of the main spiral pipe through a flange, flush with the pipe axis.

[0055] The slurry concentration sensor determines whether coarse particles have settled by comparing the concentration difference between the upper and lower parts of the pipe. For example, an ultrasonic attenuation concentration sensor is used, symmetrically installed at the top and bottom of the main spiral pipe.

[0056] The edge computing module connects to the flow sensing component via a shielded cable. It filters and calibrates the pressure, concentration, and temperature data collected by the sensor, generating a standardized flow dataset. This dataset is then compared in real-time based on an internally optimized CFD simulation model. For example, when the concentration difference between the upper and lower parts of the pipe is greater than 8% or the pressure difference increase is greater than 0.1 MPa / h, it is determined to be light deposition; when the concentration difference is greater than 15% or the pressure difference increase is greater than 0.2 MPa / h, it is determined to be heavy deposition.

[0057] In some embodiments, the device further includes: The adaptive control component, connected to the intelligent monitoring system, is used to adjust the pumping rate of the slurry or trigger emergency cleaning operations based on the slurry flow analysis results, thereby maintaining stable pipeline delivery.

[0058] Specifically, the adaptive control component and the edge computing module of the intelligent monitoring system are connected via an industrial bus. Based on flow analysis results, they automatically adjust delivery parameters or trigger emergency operations to maintain stable pipeline delivery. For example, when the edge computing module determines that there is slight deposition, the control component sends a signal to the pumping system to adjust the slurry flow rate from the usual 1.6±0.1 m / s to 1.7-1.8 m / s. By increasing the flow rate, the turbulence intensity of the slurry is enhanced, suppressing further particle settling without increasing energy consumption excessively.

[0059] In some implementations, refer to Figure 1 The modular segmented piping system also includes: A quick-connect interface is located at the end of the rotary drive mechanism section 20 away from the spiral mixing section 10, and is used to enable quick assembly and disassembly with the slurry conveying pipeline.

[0060] For example, the interface body and the fixed pipe 21 of the rotary drive mechanism section 20 are rigidly connected by butt welding. The inner diameter of the interface is the same as the inner diameter of the fixed pipe 21. The end face of the interface body facing the external conveying pipe is a concave-convex surface, and an annular positioning platform is provided on the concave-convex surface. A concave flange is provided on the external slurry conveying pipe. The concave flange is aligned with the boss of the quick connection interface. The external pipe is pushed so that the protrusion in the concave-convex surface of the interface body fits into the concave flange. The connection is completed by tightening the bolts.
