As shown in fig. 1, 3 and 8, the support plate 32 is also disposed at the mouth of the electrolytic cell 10. Second guide posts are disposed at four corners of the upper plate surface of the support plate 32, and the rod length direction of the second guide posts extends in the vertical direction. A base 31 is disposed above the supporting plate 32, guide holes matched with the second guide posts are disposed at four corners of the base 31, so that the base 31 is slidably disposed on the second guide posts, and the base 31 can perform reciprocating linear sliding movement away from or close to the supporting plate 32 along the second guide posts.
As shown in fig. 2, 3, 4, 5, 6 and 10, an inverted V-shaped guide rail 23 is disposed on the base 31, and two sets of condensation tanks 20 are symmetrically disposed on the guide rail 23 along a symmetry plane of the guide rail 23. The bottom of the condensation tank 20 is fixedly installed with a fixing plate 24, and the fixing plate 24 is slidably disposed on the guide rail 23 along the guide of the guide rail 23. The two trigger switches are respectively arranged on the corresponding fixing plates 24, and when the two groups of fixing plates 24 are close to each other and the distance is unchanged, the trigger switches send signals to control the suction pump 122 to be started for suction; when the two sets of fixing plates 24 are far away from each other, the distance between the two trigger switches increases, and the trigger switches send out signals to control the suction pump 122 to stop sucking.
As shown in fig. 1, 2, 4, 5 and 6, the two sets of fixing plates 24 are connected to each other through a second traction assembly 25 and a driving plate 26, the second traction assembly 25 includes a second support rod arranged on the base 31 and extending along the vertical direction, a second fixed pulley is arranged at the top end of the second support rod, a second traction rope is wound on the second fixed pulley, two ends of the second traction rope are connected to the fixing plates 24 and the driving plate 26 respectively, and the driving plate 26 is sleeved on the second support rod in a sliding manner. Because there are two sets of second bracing pieces, consequently two guiding holes have been seted up to the symmetry on drive plate 26, and drive plate 26 cup joints simultaneously on two sets of second bracing pieces like this, has increased the stability of removing. In order to make the movement of the fixed plate 24 smoother, two sets of second traction assemblies 25 are then also arranged on the other side of the fixed plate 24.
The two sets of condensation tanks 20 perform reciprocating linear sliding motion along the guide rails 23, and thus can move upwards along the guide rails 23 under the pulling of the driving plates 26. When moving to the top end of the guide rail 23, the two sets of condensation tanks 20 are spliced together to form a condensation chamber, and the shape of the condensation chamber can be cylindrical or conical.
As shown in fig. 2, 4 and 5, a second traction assembly 25 is further disposed on the base 31, the second traction assembly 25 includes a first support rod disposed on the base 31, and the first support rod is an L-shaped structure composed of a short rod and a long rod; the stock extends along the vertical direction, and the quarter butt is arranged on the top of stock, and the quarter butt extends along the horizontal direction. Two groups of second fixed pulleys are sequentially arranged on the short rod along the rod length direction of the short rod. The second haulage rope twines in proper order on two sets of second fixed pulleys to the both ends of second haulage rope are connected each other with positive pole stick 13 and balancing weight 21 respectively. In order to even out the force on the anode rod 13, an identical set of first pulling elements 22 is then arranged on the other side of the anode rod 13, also in a symmetrical arrangement.
A first guide post 34 is further arranged on the base 31, and a balancing weight 21 and an electromagnet 27 are sequentially sleeved on the first guide post 34 in a sliding manner from top to bottom; and a limit ring 341 for limiting the electromagnet 27 from descending along the first guide post 34 is also arranged on the first guide post 34. In order to improve the stability of the movement of the weight 21 and the electromagnet 27, two sets of first guide posts 34 are provided.
As shown in fig. 2, 3, 4, 5, 6, 7 and 8, the separating assembly 30 further includes an inflatable air bag 35 disposed between the base 31 and the support plate 32 and a covering air bag 37 disposed on a wall of the condensation tank 20 and fitted to the condensation tank 20; the inflatable air bag 35 and the covering air bag 37 are communicated with each other through an inflation tube 36; the two groups of coating air bags 37 are spliced in a butt joint mode to form the condensation cavity. The limit switch for cutting off the power supply of the electromagnet 27 is arranged at the limit plate 33, the base 31 is provided with a reset piece 38 for guiding the two groups of condensation tanks 20 to be separated from each other after the tension of the driving plate 26 is lost, and the reset piece 38 is a reset spring which extends along the guide rail 23 and is connected between the fixing plate 24 and the base 31.
As shown in fig. 1-10, in use, when electrolysis is continuously performed, the solid coarse gallium on the anode rod 13 is continuously reduced, and after all the coarse gallium is electrolyzed, the anode rod 13 sequentially passes through the material passing holes formed in the supporting plate 32 and the base 31 under the traction of the counterweight 21 through the first traction rope.
The counterweight 21 is made of ferromagnetic material, the counterweight 21 is positioned within the adsorption range of the electromagnet 27; the mass of the electromagnet 27 is heavy and is not sucked up in the reverse direction throughout the process of sucking the counter weight 21. When the counterweight 21 does not pull downward, the force applied to the counterweight 21 includes the pulling force of the first traction rope, the gravity of the first traction rope, and the attraction force of the electromagnet 27. At the instant when the weight 21 begins to move downward, the three forces are now balanced.
When the weight 21 continues to move downward, it is closer to the electromagnet 27 and the absorption force is greater. When the balancing weight 21 abuts against the upper plate surface of the driving plate 26 in the descending process, the force applied to the balancing weight 21 includes: the gravity of the driver, the adsorption force of the electromagnet 27, the pulling force of the first traction rope and the resistance force of the driving plate 26; however, at this time, the sum of the gravity of the counterweight 21 and the attraction force of the electromagnet 27 is greater than the sum of the pulling force of the first traction rope and the resistance force of the driving plate 26, and the counterweight 21 can continuously move downward until being attracted to the electromagnet 27.
In the process of descending the balancing weight 21, the anode rod 13 is continuously lifted; at the same time, the two sets of condensation channels 20 are also continuously approaching along the guide rails 23. When the counterweight 21 is adsorbed on the electromagnet 27, the two sets of condensation grooves 20 are aligned to form the condensation groove 20 with an open top, and the anode rod 13 is located in the condensation groove 20. The two sets of trigger switches send out signals, at which time the suction pump 122 starts to work, and crude gallium solution is continuously fed into the condensation tank 20. In order to rapidly solidify the solution, a refrigeration component can be arranged inside the anode rod 13, so that the anode rod 13 becomes a refrigeration rod, the solidification of the crude gallium is accelerated, and the crude gallium solution can be solidified within several seconds when falling into a condensation cavity.
The addition of the crude gallium solution continues and the mass on the susceptor 31 increases continuously. The base 31 is subjected to an increasing weight, progressively compressing the two inflatable bladders 35, which are symmetrically arranged; the electromagnet 27 is also continuously approaching the limit plate 33 downward. When the electromagnet 27 contacts with the limit plate 33, the limit plate 33 is pressed against the limit switch of the electromagnet 27 from bottom to top at the moment, so that the electromagnet 27 is powered off instantly and loses the adsorption capacity.
The suction pump 122 continues to add the crude gallium solution into the condensation chamber, at which time the susceptor 31 continues to sink; when the supporting plate 32 supports the electromagnet 27, the counterweight 21 is also supported, and at the moment, the first traction rope and the second traction rope are both in a loose state; at this time, the two sets of condensation tanks 20 are separated from each other by the return spring, and the trigger switch sends out a signal to stop the operation of the suction pump 122. The weight of the anode bar 13 with the crude gallium solidified on the surface is much larger than that of the counterweight 21, so the anode bar 13 falls into the electrolytic cell 10 again for electrolysis. In order to prevent the weight 21 from slipping out of the first guide post 34, a stop ring 341 is disposed at the top end of the first guide post 34, so that the anode rod 13 can be suspended in the electrolytic cell 10 for carrying out a charged electrolytic reaction. Although the electrolyte has a certain buoyancy effect, the buoyancy at this time is insignificant to relieve the force received by the base 31. When the anode rod 13 is continuously consumed by electrolysis, the force applied to the base 31 is gradually reduced, and the base 31 is slowly jacked up by the inflatable air bag 35. The electromagnet 27 leaves the stopper plate 33 and is electrically reconnected to restore the attraction force. The crude gallium on the anode bar 13 is continuously electrolyzed, and then enters the process of replacing the crude gallium in the next round.
Problems may be encountered in separating the two sets of condensation tanks 20, and the covering bladder 37 functions when the two sets of condensation tanks 20 are not separated from each other due to solidification adhesion of crude gallium. The gas in the inflatable air bag 35 is continuously pressed into the coating air bag 37, and the coating air bag 37 is continuously expanded, so that a bidirectional pushing force is generated between the solid crude gallium and the condensation tank 20, and the solid crude gallium is further separated from the condensation tank 20. And the surface of the coating air bag 37 is continuously expanded, so that the coating air bag 37 is separated from the solid crude gallium, and the effect of separating the solid crude gallium is achieved. In order to further improve the separation effect, the surface of the coating air bag 37 is designed to be wavy, and the shape of the solid coarse gallium formed correspondingly is spline-shaped, so that the originally cylindrical contact surface of the solid coarse gallium can be decomposed into a plurality of semi-cylindrical small contact surfaces. When the covering airbag 37 is inflated, the static friction force to be overcome is smaller, and the contact surface can be more easily separated.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
