Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vertical stirring equipment, in particular to a vertical stirring equipment based on intelligent speed regulation according to the solidification degree of materials. BACKGROUND

[0002] Stirring equipment is widely used in industrial material mixing, for example, in the process of mine backfilling, a large number of stirrers are needed to stir the slurry into paste and backfill the mining area to ensure the safety of mining.

[0003] The paste is generally composed of coal gangue, slag, fly ash and tailings, and a certain amount of gel material is added during stirring. With the progress of various reactions, the paste gradually forms and reaches the pre-solidification state. The paste is pumped to the goaf for hardening to support the mining area. However, in the process of stirring and forming the paste, due to the unevenness of the slurry, the solidification degree of the formed paste is not uniform. If the paste that has reached a certain solidification degree is stirred again, not only energy is wasted, but also the driving structure may be damaged due to the large resistance.

[0004] In addition, during the stirring process of the paste, the internal moisture evaporates. If the paste that has reached the solidification standard is stirred again, the viscosity will increase, affecting the flowability during the pumping process, reducing the pumping efficiency, and even causing local blockage, increasing the difficulty of backfilling. SUMMARY

[0011] The upper end of the stirring shaft is sleeved with a bearing which is supported on the wall surface of the through hole of the upper end of the stirring cavity and connected with the output end of the driving motor. The driving motor outputs torque to drive the stirring shaft to rotate, thereby driving the impeller of the outer ring of the stirring shaft to rotate to mix the slurry. The stirring cavity is divided into two chambers. The first chamber is used for preliminary mixing after feeding. The slurry mixed to a certain degree is fed into the second chamber for further stirring by the booster paddle to form a paste so that the solidification degree of the paste reaches the backfill standard. The discharge direction of the booster paddle is towards the discharge port, thereby continuously discharging the paste to the discharge port to increase the pressure of the paste at the discharge port, reduce the pressure difference between the discharged paste and the backfill paste, facilitate the further pressurization of the booster pump, directly backfill the high-pressure paste, reduce energy consumption, and improve the backfill efficiency. The first chamber and the second chamber are separated by the partition in the groove of the partition layer. The different solidification degrees of the paste are stirred by layering to facilitate variable-speed stirring of the paste with different solidification degrees. The booster motor is used to connect the transmission shaft and the booster shaft. In the initial state, the transmission shaft and the booster shaft have the same speed. The initial feed is in the first chamber. The slurry mixed to a certain degree forms a paste which is fed into the second chamber. The booster motor with the same direction output torque further increases the speed of the booster paddle through the booster shaft to improve the mixing performance of the booster paddle, accelerate the solidification state of the paste, and reduce the backfill time. The power supply of the booster motor can adopt the collector ring mode to supply power to the booster motor in rotation. The related power supply mode is prior art and will not be described in detail.

[0012] Further, the speed regulating device further comprises a detection assembly. The partition plate is provided with a transduction groove, and the detection assembly is arranged in the transduction groove.

The blade of the impeller is inclined downward. The transmission sheet is provided with a friction surface. The friction surface is in friction contact with the slurry in the first chamber.

[0013] The partition plate installs the detection assembly through the transduction groove. The detection assembly is used for detecting the solidification degree of the slurry. With the stirring of the impeller, the molecular movement in the slurry is promoted, the components in the slurry are uniformly mixed together, and the evaporation of the water in the slurry is accelerated, thereby promoting the solidification of the slurry and forming a paste. Compared with the slurry, the viscosity of the paste is larger. Due to the inclined downward discharge of the blade of the impeller, the transmission sheet and the upper layer of the slurry move at different speeds. The transmission sheet moves relative to the slurry. With the stirring, the slurry gradually forms a paste, the viscosity increases, the transmission sheet moves along the transduction groove under the friction resistance of the slurry, the pry bar moves along the inner circle of the induction coil, the induction coil moves in the cutting magnetic induction line and generates an induced current. The more uniform the stirring is, the greater the viscosity of the paste is, and the more the paste tends to solidify. That is, the induced current and the solidification degree of the paste are positively correlated, thereby detecting the solidification degree of the paste on the transmission sheet in real time.

[0014] Further, the induction coil and the booster motor are electrically connected.

[0015] The current generated on the induction coil and the control current of the booster motor are negatively correlated, that is, the greater the solidification degree of the paste formed by stirring, the greater the current on the induction coil through the friction energy conversion with the transmission sheet, and the smaller the output speed of the booster motor; when the solidification degree of the paste is small, the smaller the current generated on the induction coil through the friction energy conversion, the greater the output speed of the booster motor, thereby ensuring the uniformity of the paste after stirring, and the induction coil can transmit the collected current signal to the controller to control the input current of the booster motor, thereby controlling the output speed of the booster motor.

[0016] Further, the partition plate is provided with a blanking groove, the first cavity is communicated with the second cavity through the blanking groove, and the blanking groove and the energy conversion groove are arranged in sequence along the rotation direction of the partition plate.

[0017] The blanking groove is used to communicate the first cavity and the second cavity, the blanking groove is kept in a closed state during the initial stirring process after the feeding of the first cavity is completed, the slurry is stirred to a certain degree to form a paste, and then the paste is fed into the second cavity for further stirring to evaporate the moisture in the paste and promote the solidification of the paste, the paste is guided through the discharge port and further pressurized by the booster pump for filling the mining area, and the blanking groove and the energy conversion groove are arranged in sequence, so that the slurry in the first cavity that meets the standard can be directly fed into the second cavity, the injection efficiency is improved, and the power consumption is increased.

[0018] Further, the speed regulating device further comprises a disconnecting plate and an adjusting cylinder, the induction coil and the adjusting cylinder are electrically connected, the partition plate is provided with a cut-off groove, the adjusting cylinder is arranged in the cut-off groove, the output end of the adjusting cylinder is in transmission connection with the disconnecting plate, the cut-off groove is communicated with the blanking groove, the disconnecting plate is in sliding connection with the cut-off groove, and the end of the disconnecting plate away from the adjusting cylinder is inserted into the blanking groove.

[0019] The disconnecting plate and the adjusting cylinder in the cut-off groove are used to control the on-off of the blanking groove, thereby controlling the conduction state of the first cavity and the second cavity, in the initial state, the disconnecting plate is inserted into the blanking groove, so that the blanking groove is in a cut-off state, when it is detected that the solidification degree of the slurry on the upper end of the transmission sheet meets the standard to form a paste, the output end of the adjusting cylinder is retracted, so that the disconnecting plate moves to the cut-off groove, the blanking groove enters a conduction state, so that the paste flows into the second cavity through the blanking groove for further stirring, when the local paste is discharged into the second cavity, the output displacement of the adjusting cylinder is adjusted, so that the disconnecting plate re-cuts off the blanking groove until new paste appears.

[0020] As an optimization, the roughness of the friction surface is gradually changed, and the roughness of the friction surface gradually decreases along the rotation direction of the partition plate. Through the roughness gradual change, the friction between the friction surface and the paste is increased, thereby facilitating the improvement of the transmission efficiency.

[0021] As optimization, the transmission sheet is provided with a material guide surface, and the end of the material guide surface faces the dropping groove.

[0038] The speed regulating device 3 comprises a booster motor 34, the output torque direction of the booster motor 34 is the same as the output torque direction of the driving motor 4, a transmission cavity is arranged on the transmission shaft 211, the booster motor 34 is arranged in the transmission cavity, the output end of the booster motor 34 is in transmission connection with the booster shaft 212, the transmission shaft 211 is in transmission connection with the booster shaft 212 through the booster motor 34, and the discharge direction of the booster paddle 23 is towards the lower discharge port 12.

[0039] The upper end of the stirring shaft 21 is sleeved with a bearing supported on the wall surface of the through hole of the upper end of the stirring cavity 11 and connected with the output end of the driving motor 4. The stirring shaft 21 is driven to rotate by the output torque of the driving motor 4, so as to drive the impeller 22 at the outer circle of the stirring shaft 21 to rotate and mix the slurry. The stirring cavity 11 is provided with a divided cavity. The first cavity 111 is used for preliminary mixing after feeding. The slurry mixed to a certain degree is sent into the second cavity 112 for further stirring by the booster paddle 23 to form a paste, so that the solidification degree of the paste reaches the backfill standard. The discharge direction of the booster paddle 23 is towards the discharge port 12, so as to continuously discharge the paste to the discharge port 12, increase the pressure of the paste in the discharge port 12, reduce the pressure difference between the discharge paste and the backfill paste, facilitate the further pressure increase of the booster pump 5, directly backfill the high-pressure paste, reduce the energy consumption, and improve the backfill efficiency. The first cavity 111 and the second cavity 112 are separated by the partition plate 24 in the groove of the partition layer 113. The paste with different solidification degrees is subjected to variable-speed stirring by layered stirring. The booster motor 34 is used for connecting the transmission shaft 211 and the booster shaft 212. In the initial state, the transmission shaft 211 and the booster shaft 212 have the same speed. The initial material is fed into the first cavity 111. The slurry stirred to a certain degree forms a paste and is sent into the second cavity 112. The booster motor 34 with the same direction output torque further increases the speed of the booster paddle 23 through the booster shaft 212, improves the mixing performance of the booster paddle 23, accelerates the solidification state of the paste, reduces the backfill time, and the power supply of the booster motor 34 can adopt the collector ring mode for rotating power supply of the booster motor 34. The related power supply mode is prior art and will not be described in detail.

[0040] Further, the speed regulating device 3 further comprises a detection assembly 31. The partition plate 24 is provided with a transduction groove 243, and the detection assembly 31 is arranged in the transduction groove 243. The detection assembly 31 comprises a transmission sheet 311, a pry bar 312 and an induction coil 313. The transmission sheet 311 and the induction coil 313 are arranged in the transduction groove 243 respectively. The transmission sheet 311 and the pry bar 312 are in transmission connection. The pry bar 312 is a magnet. One end of the pry bar 312 is inserted into the inner circle of the induction coil 313. The blade of the impeller 22 is inclined downward. The transmission sheet 311 is provided with a friction surface 3111. The friction surface 3111 is in friction contact with the slurry in the first cavity 111.

[0041] The baffle 24 is provided with a transducing groove 243, and the detection assembly 31 is arranged in the transducing groove 243 and used for detecting the solidification degree of the slurry. When the impeller 22 stirs the slurry, the molecular movement in the slurry is promoted, so that the components in the slurry are uniformly mixed together, and the evaporation of water in the slurry is accelerated, so as to promote the solidification of the slurry and form a paste. Compared with the slurry, the paste has a larger viscosity. Since the blade of the impeller 22 is inclined downward to discharge the material, the transmission sheet 311 and the upper slurry move at different speeds. The transmission sheet 311 moves relative to the slurry. With the stirring, the slurry gradually forms a paste, the viscosity increases, the transmission sheet 311 is subjected to the frictional resistance of the slurry, moves along the transducing groove 243, so that the pry bar 312 moves along the inner ring of the induction coil 313. The induction coil 313 moves along the magnetic induction line and generates an induced current. The more uniform the stirring is, the greater the viscosity of the paste is, and the more the paste tends to solidify. That is, the induced current and the solidification degree of the paste are positively correlated, so that the solidification degree of the paste on the transmission sheet 311 is detected in real time.

[0042] Further, the induction coil 313 and the booster motor 34 are electrically connected.

[0043] The current generated on the induction coil 313 and the control current of the booster motor 34 are negatively correlated. That is, the greater the solidification degree of the paste formed by stirring is, the greater the current on the induction coil 313 is, and the smaller the output rotating speed of the booster motor 34 is. When the solidification degree of the paste is small, the current generated on the induction coil 313 is small through the frictional transduction of the transmission sheet 311, and the output rotating speed of the booster motor 34 is large. The uniformity of the paste after stirring is ensured. The induction coil 313 can transmit the collected current signal to the controller, so as to control the input current of the booster motor 34 through the controller, thereby controlling the output rotating speed of the booster motor 34.

[0044] Further, the baffle 24 is provided with a feeding groove 241, the primary cavity 111 is communicated with the secondary cavity 112 through the feeding groove 241, and the feeding groove 241 and the transducing groove 243 are arranged in sequence along the rotating direction of the baffle 24.

[0045] The first chamber 111 and the second chamber 112 are communicated through the blanking groove 241. After the feeding of the first chamber 111 is completed, the blanking groove 241 remains in a closed state during the initial stirring process. When the slurry is stirred to a certain degree to form a paste, the paste is sent into the second chamber 112 for further stirring to evaporate the moisture in the paste and promote the solidification of the paste. When the solidification degree reaches a standard, the paste is guided through the discharge port 12 and further pressurized by the booster pump 5 to fill the mine area. The blanking groove 241 and the conversion groove 243 are arranged in sequence, so that the slurry reaching the standard in the first chamber 111 can be directly sent into the second chamber 112, improving the feeding efficiency and avoiding the full-power stirring in the first chamber 111 to increase the power consumption.

[0046] Further, the speed regulating device 3 further includes a breaking plate 32 and an adjusting cylinder 33. The inductive coil 313 is electrically connected with the adjusting cylinder 33. The baffle 24 is provided with a cut-off groove 242, and the adjusting cylinder 33 is arranged in the cut-off groove 242. The output end of the adjusting cylinder 33 is drivingly connected with the breaking plate 32. The cut-off groove 242 and the blanking groove 241 are communicated. The breaking plate 32 is slidingly connected with the cut-off groove 242. The end of the breaking plate 32 away from the adjusting cylinder 33 is inserted into the blanking groove 241.

[0047] The breaking plate 32 and the adjusting cylinder 33 in the cut-off groove 242 control the on-off state of the blanking groove 241, so as to control the conduction state of the first chamber 111 and the second chamber 112. In the initial state, the breaking plate 32 is inserted into the blanking groove 241, so that the blanking groove 241 is in a cut-off state. When it is detected that the paste on the upper end of the transmission sheet 311 reaches a standard to form a paste, the output end of the adjusting cylinder 33 is retracted, so that the breaking plate 32 moves to the cut-off groove 242. The blanking groove 241 enters an on state, so that the paste flows into the second chamber 112 through the blanking groove 241 for further stirring. When the paste in the second chamber 112 is discharged, the output displacement of the adjusting cylinder 33 makes the breaking plate 32 cut off the blanking groove 241 again until new paste appears.

[0048] As an optimization, the roughness of the friction surface 3111 is gradually changed. The roughness of the friction surface 3111 gradually decreases along the rotation direction of the baffle 24. Through the gradual change of the roughness, the friction between the friction surface 3111 and the paste is increased, so as to improve the transmission efficiency.

[0049] As an optimization, the transmission sheet 311 is provided with a material guiding surface 3112. The end of the material guiding surface 3112 faces the blanking groove 241. The paste reaching the standard is guided into the blanking groove 241 through the material guiding surface 3112 at the end of the transmission sheet 311.

[0050] As optimization, the transmission sheet 311 is provided with a reset spring away from the side of the intercepting groove 242, and the reset spring is in abutment with the wall surface of the transduction groove 243 away from the end of the transmission sheet 311. By setting the reset spring, the transmission sheet 311 is reset, when the slurry on the upper layer of the transmission sheet 311 is not formed, the transmission sheet 311 cannot be driven to move, or is moved to a certain distance, that is, the adjusting cylinder 33 does not work, and the blanking groove 241 is not conducted.

[0051] The working principle of the present application is as follows: the first cavity 111 is used for preliminary mixing after feeding, the slurry mixed to a certain degree is sent into the second cavity 112, and further stirring is carried out through the booster paddle 23 to form a paste, so that the solidification degree of the paste reaches the backfill standard, the discharge direction of the booster paddle 23 is towards the discharge port 12, so that the paste is continuously discharged to the discharge port 12, the paste pressure of the discharge port 12 is increased, the pressure difference between the discharge paste and the backfill paste is reduced, the booster pump 5 is further boosted, the high-pressure paste is directly backfilled, the energy consumption is reduced, and the backfill efficiency is improved; the blade of the impeller 22 is inclined downward to discharge, so that the transmission sheet 311 and the slurry on the upper layer move at different speeds, the transmission sheet 311 moves relative to the slurry, with the stirring, the slurry gradually forms a paste, the viscosity increases, the transmission sheet 311 is moved along the transduction groove 243 under the friction resistance of the slurry, the pry bar 312 is moved along the inner circle of the induction coil 313, the induction coil 313 moves in a cutting magnetic induction line, and an induced current is generated, the more uniform the stirring is, the greater the viscosity of the paste is, and the more the paste tends to solidify, that is, the induced current and the solidification degree of the paste are positively correlated, so that the solidification degree of the paste on the transmission sheet 311 is detected in real time; the current generated on the induction coil 313 and the control current of the booster motor 34 are negatively correlated, that is, the greater the solidification degree of the paste formed by stirring is, the greater the current on the induction coil 313 is through the friction transduction with the transmission sheet 311, and the smaller the output speed of the booster motor 34 is; when the solidification degree of the paste is small, the current generated on the induction coil 313 is small through the friction transduction of the transmission sheet 311, and the output speed of the booster motor 34 is greater, so as to ensure the uniformity of the paste after stirring.
