Based on the above technical scheme, because the telescopic rod 302 is controlled to stretch and draw back to drive the stirring rod 304 to do reciprocating swing and break up the granule, lead to the granule probably to have mutually coagulated into big granule in the time quantum of two timing swings, can not timely discernment to the formation of big granule, and because the formation of big granule leads to the mixed effect of medicament and mineral granule not ideal, in addition, also can not in time discern the condition that the granule flows along with the vortex is synchronous to lead to the stirring efficiency to reduce in advance, and then for solving above-mentioned technical problem, propose following technical scheme.
In order to solve the above technical problems, as shown in fig. 9 to 12, when the shunt assembly 6 is arranged to cooperate with the stirring assembly 3 to break up the vortex, particles collide, the shunt assembly 6 comprises shunt blades 601 symmetrically arranged at two sides of the stirring rod 304, in a normal state, the shunt blades 601 are arranged in parallel with the stirring rod 304, the arrangement of the shunt blades 601 can increase the area of the stirring rod 304, so that the breaking force of the stirring rod 304 to the vortex is increased when the stirring rod 304 reciprocates, mineral particles and medicament are broken up better, one side of the two opposite sides of the shunt blades 601 is fixedly connected with a gear shaft 602, two ends of the gear shaft 602 penetrate through the stirring rod 304 and are fixedly connected with the shunt blades 601, the gear shaft 602 is rotatably arranged on the stirring rod 304, and lifting racks 604 meshed with the gear shaft 602 are arranged inside the stirring rod 304; lifting rack 604 sliding connection is on the inside wall of puddler 304, lifting rack 604 is provided with driving tooth 603 far away from one side of gear shaft 602, driving tooth 603 meshing has driving gear 606, the inside of puddler 304 is fixed to be provided with elevator motor 605, driving gear 606 is fixed to be set up the output at elevator motor 605, drive driving gear 606 through control elevator motor 605 rotates, driving gear 606 passes through driving tooth 603 and drives lifting rack 604 and go up and down, thereby drive gear shaft 602 rotation, and then make reposition of redundant personnel leaf 601 rotate 90, become the state of perpendicular puddler 304, form the pointed cone, as shown in fig. 12, make the rivers through puddler 304 both sides can follow the rivers that form the mutual collision on reposition of redundant personnel leaf 601, thereby make granule and medicament in the liquid can collide and even contact mineralization.
Under the assistance of the buffer spring 503, when the partition block 501 is impacted by particles and liquid thrown out by the arc-shaped blades 408, vibration can be generated, the compression amount of the buffer spring 503 can reflect the vibration amplitude of the partition block 501, the impact of large particles can increase the compression amount of the buffer spring 503, so that the vibration amplitude of the partition block 501 is larger, and the impact of particles and liquid which are unevenly mixed can enable the compression amounts of all the buffer springs 503 to be inconsistent, so that the vibration amplitudes of the partition block 501 are different.
The mixing condition of the current particles and the liquid is judged by detecting the vibration amplitude condition of the dividing block 501 in real time, and the situation that large particles are coagulated or the situation that particles are separated along with synchronous motion of vortex is judged, so that the problem that the telescopic rod 302 stretches and contracts to drive the stirring rod 304 to destroy the vortex of the liquid is solved, or the problem that the stirring rod 304 rotates by 90 degrees to enable particles in the liquid to collide with each other while the lifting motor 605 drives the diversion blades 601 to reverse is solved.
The magnitude of the impact force of the arc-shaped blades 408, which are evenly mixed and thrown out of the liquid and particles and strike the dividing blocks 501, is different at different rotation speeds, and the range of the vibration amplitude generated by the dividing blocks 501 at different rotation speeds can be set as a reference value.
When the vibration amplitude of the partition block 501 is detected to be integrally larger than the reference value, it can be judged that large particles existing in the current liquid are more, the cohesiveness among the particles is stronger, the buffer spring 503 is greatly compressed due to the fact that the impact force of the large particles on the partition block 501 is larger, and then it can be judged that the stirring force of the current stirring assembly 3 is smaller, so that the mineral particles and the medicament are seriously adhered to each other and sink into the bottom of the stirring barrel 101, at the moment, the rotation speeds of the feeding motor 201 and the dispersing motor 401 are controlled to be synchronously increased, and therefore the stirring force of the telescopic rod 302 and the stirring rod 304 on the liquid is increased, and meanwhile, the suction force of the spiral blades 203 and the dispersing force of the arc blades 408 are increased, so that the liquid circulation process inside the stirring barrel 101 is accelerated while the large particles are accelerated to be decomposed, the mutual adhesion among the particles in the liquid is prevented, and the pre-stirring efficiency is influenced.
When the vibration amplitude of the dividing blocks 501 is uneven and the difference is large, it can be determined that the particles in the current liquid are not in contact with each other and unevenly float in the liquid, so that the particles transported to the arc-shaped blades 408 by the spiral blades 203 are uneven, the impact force to all the dividing blocks 501 is uneven, the compression amount of the buffer springs 503 is inconsistent, the difference is large, and then it can be determined that the particles in the current liquid are synchronously rotating along with the vortex, the medicament and the mineral particles are relatively static and can not be well mixed, which is equivalent to being in a segregation state, at this time, the telescopic rod 302 is controlled to stretch and retract, the stirring rod 304 is driven to reciprocate by taking the fixed block 301 at the bottom as the center of a circle, the vortex formed by stirring is scattered, so that the mineral particles and the medicament synchronously flowing along with the vortex are scattered, and meanwhile, the lifting motor 605 is controlled to rotate to drive the dividing blades 601 to be changed into the state of the vertical stirring rod 304 from the state of the parallel stirring rod 304, at this time, the dividing blades 601 form a taper, the water flow passing through the two sides of the stirring rod 304 forms an interactive collision water flow after passing through the dividing blades 601, and the particles in the liquid can be uniformly collided and mineralized.
The vibration amplitude of the partition block 501 is reflected by the deformation amount of the buffer spring 503, when the vibration amplitude of the partition block 501 is detected to be integrally larger than a reference value, it can be judged that mineral particles and medicaments in the liquid are seriously adhered to each other to form large particles, at this time, the rotation speeds of the feeding motor 201 and the dispersing motor 401 are synchronously increased, so that the stirring force of the stirring rod 304 on the liquid is increased, the suction force of the spiral blade 203 and the dispersing force of the arc-shaped blade 408 are increased, and the mutual adhesion of the particles in the liquid is prevented from being seriously adhered to each other, and the pre-stirring efficiency is influenced.
The vibration amplitude of the dividing block 501 is reflected through the deformation amount of the buffer spring 503, when the vibration amplitude of the dividing block 501 is detected to be uneven, and when the difference is large, the particles in the current liquid can be judged to synchronously rotate along with the vortex to form a segregation state, at the moment, the telescopic rod 302 is controlled to stretch and retract to drive the stirring rod 304 to reciprocate to swing so as to break up the vortex formed by stirring, meanwhile, the lifting motor 605 is controlled to rotate to drive the dividing blade 601 to be changed into a state of vertical stirring rod 304, so that water flows passing through two sides of the stirring rod 304 form water flows which are mutually collided after passing through the dividing blade 601, and the state that particles and medicaments in the liquid synchronously rotate along with the vortex is broken up, so that the pre-stirring effect is ensured.
The invention discloses an application of a stirring tank in the field of mineral flotation, which is particularly applied to a stirring step before mineral particles enter a flotation tank for flotation, and the mineral particles are required to be pre-stirred through the stirring tank before entering the flotation tank for flotation, so that interaction between the mineral particles and a medicament is accelerated, and full contact and fusion of the mineral particles and the medicament are ensured.
