[0002] Metallurgy is a method of bringing ore, concentrated ore or other raw materials into contact with aqueous solution or other liquids to transfer the useful metals contained in the raw materials into liquid phase through chemical reactions, and then separating and enriching the various useful metals contained in the liquid phase, and finally recovering them in the form of metals or other compounds. It mainly includes unit operations such as leaching, liquid-solid separation, solution purification, metal extraction from solution and wastewater treatment.

[0003] According to Chinese patent application number 202220095925.9, an efficient hydrometallurgical reaction tank includes a tank body and a reaction chamber, wherein the reaction chamber is arranged at the upper end of the tank body, a filter box is arranged below the reaction chamber inside the tank body, a material guide pipe is arranged between the reaction chamber and the filter box, a heating chamber is arranged inside the tank body near the outer side of the reaction chamber, a heating plate is arranged inside the heating chamber, and a temperature sensor is arranged on one side inside the reaction chamber.

[0004] According to the above-cited application documents, the impurities mixed in the reaction liquid can be filtered through the filter net to purify the reaction liquid, and at the same time facilitate the secondary utilization of the reaction liquid. In order to prevent a large amount of impurities from accumulating on the filter net, the impurities remaining on the end surface of the filter net are cleaned by moving a soft-bristle brush. Although the purpose of cleaning the filter net can be achieved, the soft-bristle brush cannot clean the impurities in the holes of the filter net, resulting in the filter net being prone to clogging after long-term use, which in turn has an adverse effect on the normal filtration of the reaction liquid.

[0005] To this end, we proposed a high-efficiency metallurgical reaction tank. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-3 The figure shows a high-efficiency metallurgical reaction tank, including a reaction tank 1 for metallurgy and a filter screen 5. The filter screen 5 is fixedly installed in the inner cavity of the reaction tank 1. The inner cavity of the reaction tank 1 is provided with an anti-blocking component for preventing the filter screen 5 from being blocked. The reaction tank 1 can mix the metal to be metallurgically used and the reaction liquid to facilitate the smelting of the metal.

[0023] The anti-blocking component includes a transmission shaft 6 and a transmission plate 7. The transmission shaft 6 is longitudinally rotatably installed in the inner cavity of the reaction tank 1, and one end of the transmission shaft 6 passes through the upper end surface of the filter screen 5. At least one U-shaped plate is fixedly installed at the edge of the lower end surface of the filter screen 5. A knocking plate 12 is rotatably installed on the inner wall of the U-shaped plate through a torsion spring. When the reaction of the metal and the reaction liquid is completed, the reaction liquid is discharged into the inner cavity of the reaction tank 1. When the reaction liquid passes through the filter screen 5, the filter screen 5 can intercept the solid impurities contained in the reaction liquid to its own upper end surface, thereby achieving the purpose of removing impurities from the reaction liquid.

[0024] It should be noted that impurities with smaller volumes in the reaction liquid will enter the internal holes of the filter 5 along with the reaction liquid. When more impurities accumulate in the holes at the same position of the filter 5, the filter 5 will be blocked. At this time, the knocking plate 12 is rotated to separate one end of the knocking plate 12 from the lower end surface of the filter 5, and then the pressure applied to the outside of the knocking plate 12 is removed. Under the action of the torsion spring, the knocking plate 12 is quickly reset. At this time, the lower end surface of the filter 5 is subjected to the huge impact force of the knocking plate 12, which causes it to vibrate. At this time, the impurities in the internal holes of the filter 5 are vibrated to the outside of the filter 5, thereby achieving the purpose of cleaning the impurities accumulated inside the holes of the filter 5 and preventing adverse effects on the subsequent removal of impurities from the reaction liquid.

[0025] At least one transmission plate 7 is fixedly installed on the outer wall of the transmission shaft 6, and the transmission plate 7 is located below the knocking plate 12. A baffle 8 for rotating the knocking plate 12 is fixedly installed on the side of the transmission plate 7 close to the knocking plate 12, wherein multiple knocking plates 12 are installed in a ring-shaped distribution at the edge of the lower end surface of the filter screen 5, and multiple transmission plates 7 are fixedly installed in a ring-shaped distribution on the outer wall of the transmission shaft 6. When the transmission shaft 6 rotates, one end of multiple baffles 8 can be made to contact the outer walls of multiple knocking plates 12 at the same time, so as to realize the synchronous rotation of multiple knocking plates 12 and the synchronous knocking of the filter screen 5, which can increase the knocking force on the filter screen 5 and also increase the vibration area of ​​the filter screen 5, so as to realize the synchronous knocking of the filter screen 5 from different directions, so as to facilitate the processing of impurities in the holes of different positions of the filter screen 5.

[0026] A driving motor 2 is fixedly installed on the outer wall of the reaction tank 1. The power output end of the driving motor 2 and the outer wall of the transmission shaft 6 are fixedly sleeved with a tensioning wheel. The two tensioning wheels are rotatably connected by a tensioning belt. An active groove for rotating the tensioning belt is provided on the outer wall of the reaction tank 1. When the driving motor 2 is started, one of the tensioning wheels can be rotated, and the other tensioning wheel can be synchronously rotated under the action of the tensioning belt, thereby finally driving the transmission shaft 6 and improving the stability and sustainability of the rotation of the transmission shaft 6.

[0027] At least one cleaning plate 10 is fixedly installed on the outer wall of the transmission shaft 6. The cleaning plate 10 is located between the transmission plate 7 and the filter screen 5, and a plurality of bristles 11 are fixedly installed on the side of the cleaning plate 10 close to the filter screen 5. The ends of the plurality of bristles 11 away from the cleaning plate 10 are in contact with the lower end surface of the filter screen 5. The outer wall of the transmission shaft 6 is fixedly installed with a plurality of cleaning plates 10 in a ring-shaped distribution. When the transmission shaft 6 rotates, the bristles 11 can clean the impurities remaining on the lower end surface of the filter screen 5 to prevent a large amount of impurities from remaining on the lower end surface of the filter screen 5 and affecting the normal removal of impurities of the reaction liquid.

[0028] A placement groove compatible with the transmission shaft 6 is opened at the bottom of the inner cavity of the reaction tank 1, and a bearing 9 is fixedly installed in the inner cavity of the placement groove. The inner wall of the bearing 9 is fixedly connected to the outer wall of the transmission shaft 6. The bearing 9 can serve as a medium connecting the transmission shaft 6 and the bottom of the reaction tank 1, effectively reducing the friction generated during the rotation of the transmission shaft 6 and improving the smoothness and stability of the rotation of the transmission shaft 6.

[0029] A reaction box 4 is fixedly installed in the inner cavity of the reaction tank 1, and a stirring shaft 3 is rotatably installed in the inner cavity of the reaction box 4. A transmission motor for providing power to the stirring shaft 3 is fixedly installed on the upper end surface of the reaction tank 1, and the power output end of the transmission motor is fixedly connected to one end of the stirring shaft 3. At the same time, a conduit for feeding reaction liquid and a feeding pipe for metal feeding are fixedly installed on the upper end surface of the reaction tank 1. When the reaction liquid and metal in the reaction box 4 reach a certain amount, the transmission motor is started to realize the rotation of the stirring shaft 3, so as to realize the simultaneous stirring of the metal and the reaction liquid, so as to accelerate the reaction rate between the reaction liquid and the metal.

[0030] The reaction box 4 is located directly above the filter screen 5, and a drainage pipe connected to its own inner cavity is fixedly installed at one end of the reaction box 4 close to the filter screen 5. A solenoid valve is installed in the inner cavity of the drainage pipe. When the reaction liquid and the metal have completed the reaction in the reaction box 4, the solenoid valve is started to connect the two ends of the drainage pipe. At this time, the reaction liquid in the reaction box 4 flows to the upper end surface of the filter screen 5 under its own gravity.
