[0039] The driving mechanism 21 includes a positioning ring 211; illustratively, as Figure 4 shown.

[0040] The inner wall of the positioning ring 211 is fixedly connected with a motor mounting seat 212, and a servo motor 213 is arranged on the top of the motor mounting seat 212. The output end of the servo motor 213 extends to the bottom of the motor mounting seat 212, and the output end of the servo motor 213 is drivingly connected with a linkage spindle 214, and the bottom of the linkage spindle 214 is rotatably connected with a plane bearing 215. The outer wall of the linkage spindle 214 is provided with two groups of first guide grooves 216, and the two groups of the first guide grooves 216 are connected to each other. The outer wall of the linkage spindle 214 is also provided with two groups of second guide grooves 217, and the two groups of the second guide grooves 217 are connected to each other. The two groups of the first guide grooves 216 and the two groups of the second guide grooves 217 are interconnected, and a linkage part 218 is provided in the two groups of the first guide grooves 216 and the two groups of the second guide grooves 217. A dual-axis motor is embedded and installed on the side of the linkage main shaft 214 close to the top, and the output ends of the dual-axis motors are both transmission-connected with driving gears 219, and the two groups of the driving gears 219 are both meshingly connected with driven gears 2110, and threaded rods 2111 are embedded and installed on the two groups of the driven gears 2110, and the bottom ends of the two groups of the threaded rods 2111 are rotatably connected to the top of the plane bearing 215, and the top ends of the two groups of the threaded rods 2111 are slidably fitted and connected to the bottom of the motor mounting seat 212.

[0041] The linkage part 218 includes a vertical rod 2181; illustratively, as Figure 5 shown.

[0042] The vertical rod 2181 is embedded and installed at the center of the central axis of the linkage main shaft 214, and a limiting cross bar 2182 is embedded and installed on the outer wall of the vertical rod 2181 near the top. The outer wall of the vertical rod 2181 is also provided with a hollow sliding cavity 2183, and the two sides of the hollow sliding cavity 2183 are communicated with the second guide groove 217. The inner wall of the hollow sliding cavity 2183 is fixedly connected with several groups of micro waterproof motors 2184, and the output ends of several groups of the micro waterproof motors 2184 are all transmission-connected with screw rods 2185, and the screw rods 2185 are all threadedly connected with movable cross bars 2186, and both ends of several groups of the movable cross bars 2186 and the limiting cross bars 2182 extend to the outside of the linkage main shaft 214.

[0043] Specifically, the output end of the servo motor 213 drives the linkage main shaft 214 to rotate, while making several groups of movable cross bars 2186 and the limiting cross bars 2182 rotate synchronously, so as to stir the highly concentrated brine in the lining tank 3. The output end of the micro waterproof motor 2184 drives the screw rod 2185 to rotate, while making several groups of movable cross bars 2186 move to different positions in the hollow sliding cavity 2183, so as to shorten the distance between several groups of movable cross bars 2186 after the highly concentrated brine in the lining tank 3 is reduced due to high-temperature evaporation, increase the stirring frequency of the remaining highly concentrated brine, improve the mixing efficiency of the remaining highly concentrated brine, and accelerate the crystallization of the highly concentrated brine.

[0044] The recovery mechanism 22 includes a linkage ring 221; illustratively, as Figure 6 and Figure 7 shown.

[0045] The inner wall of the linkage ring 221 is fixedly connected with four groups of fan ring plates 222, and a recovery chamber 223 is opened between one side wall of each two groups of the fan ring plates 222. The width of the recovery chamber 223 is the same as the diameter of the movable cross bar 2186, and the recovery chamber 223 is sleeved on the outer wall of the movable cross bar 2186. A storage shell 225 is arranged at the top of the linkage ring 221 and near the edge, and a guide portion 224 is arranged at the connection between the storage shell 225 and the linkage ring 221. A suction pump 226 is arranged at the top of the linkage ring 221, and the input end of the suction pump 226 is communicated with the storage shell 225, and the top output end of the suction pump 226 is threadedly connected with a storage tank 227. A linkage arm 228 is fixedly connected between the other side walls of 222, and internal threaded holes 229 are opened on the surfaces of the two groups of the linkage arms 228, and the internal threaded holes 229 are threadedly connected to the threaded rod 2111, and the ends of the two groups of the linkage arms 228 are movably fitted and connected to the outer wall of the vertical rod 2181, and a step surface 2210 is provided at the bottom of the linkage ring 221 and near both ends, and a plurality of groups of suction nozzles 2211 are embedded and installed at the bottom of the step surface 2210, and the plurality of groups of suction nozzles 2211 are arranged in a circular array with the central axis of the linkage ring 221 as the center, and the other ends of the plurality of groups of suction nozzles 2211 extend into the storage shell 225, and a liquid level sensor 2212 is also provided at the bottom of the linkage ring 221.

[0046] Specifically, the threaded rod 2111 is threadedly connected with the internal threaded hole 229 while rotating, so that the linkage ring 221 moves to different heights of the liner tank 3 along the radial direction of the threaded rod 2111. When the liner tank 3 is filled with highly concentrated brine, the position of the highly concentrated brine is constantly detected by the liquid level sensor 2212, so that the linkage ring 221 is in a state of splash-proofing the highly concentrated brine. When the highly concentrated brine falls to different heights of the liner tank 3 due to evaporation, the threaded rod 2111 continues to rotate, so that the linkage ring 221 The liquid level sensor 2212 on the upper part follows the drop of the liquid level of the highly concentrated brine. During the drop of the linkage ring 221, the limiting cross bar 2182 or several groups of movable cross bars 2186 gradually move into the recovery chamber 223. At the same time, the suction nozzle 2211 moves to different positions on the inner wall of the liner tank 3. During the continuous suction process of the suction pump 226, the highly concentrated brine crystals remaining on the limiting cross bar 2182 or several groups of movable cross bars 2186 and the inner wall of the liner tank 3 are adsorbed into the storage tank 227.

[0047] The guide portion 224 includes an adsorption tube 2241; illustratively, as Figure 8 shown.

[0048] Both ends of the adsorption tube 2241 are closed structures. A plurality of through holes 2242 are provided on the outer wall of the adsorption tube 2241 and on one side close to the recovery chamber 223 . A flow guide tube 2243 is connected between the top of the adsorption tube 2241 and the storage shell 225 .

[0049] Specifically, the length of the adsorption tube 2241 is equal to the length of the limiting cross bar 2182 and the movable cross bar 2186, and a plurality of through holes 2242 opened on the surface of the adsorption tube 2241 are used to carry out adsorption treatment at different positions on the surface of the limiting cross bar 2182 or the movable cross bar 2186 entering the recovery chamber 223, thereby reducing the residual crystals on the surface of the stirring cross bar and reducing the labor intensity of manual recovery of crystals.

[0050] A recovery device for high-concentration brine treatment proposed by an embodiment of the present invention has the following working principle:

[0051] After being connected to the heater through the heater connection valve 6, high-temperature gas is injected into the heat preservation chamber 5 to gradually increase the temperature around and at the bottom of the liner tank 3, so as to heat the high-concentration brine in the liner tank 3. The steam recovery valve 7 recovers the steam generated by the crystallization of the high-concentration brine after the temperature is increased.

[0052] The output end of the servo motor 213 drives the linkage main shaft 214 to rotate, and at the same time, several groups of movable cross bars 2186 and the limit cross bars 2182 rotate synchronously, so as to stir the highly concentrated brine in the liner tank 3. The output end of the micro waterproof motor 2184 drives the screw rod 2185 to rotate, and at the same time, several groups of movable cross bars 2186 move to different positions in the hollow sliding cavity 2183, so as to shorten the spacing between several groups of movable cross bars 2186 after the highly concentrated brine in the liner tank 3 is reduced due to high-temperature evaporation, increase the stirring frequency of the remaining highly concentrated brine, improve the mixing efficiency of the remaining highly concentrated brine, and accelerate the crystallization of the highly concentrated brine;

[0053] The threaded rod 2111 is rotated and threadedly connected with the internal threaded hole 229, so that the linkage ring 221 moves to different heights of the liner tank 3 along the radial direction of the threaded rod 2111. When the liner tank 3 is filled with highly concentrated brine, the position of the highly concentrated brine is constantly detected by the liquid level sensor 2212, so that the linkage ring 221 is in a state of splash-proofing the highly concentrated brine. When the highly concentrated brine falls to different heights of the liner tank 3 due to evaporation, the threaded rod 2111 continues to rotate, so that the linkage ring 221 The liquid level sensor 2212 follows the drop of the liquid level of the highly concentrated brine. During the drop of the linkage ring 221, the limit cross bar 2182 or a plurality of groups of movable cross bars 2186 gradually move into the recovery chamber 223. At the same time, the suction nozzle 2211 moves to different positions of the inner wall of the liner tank 3. During the continuous suction of the suction pump 226, the highly concentrated brine crystals remaining on the limit cross bar 2182 or a plurality of groups of movable cross bars 2186 and the inner wall of the liner tank 3 are adsorbed into the storage tank 227.

[0054] By making the length of the adsorption tube 2241 equal to the length of the limiting cross bar 2182 and the movable cross bar 2186, and utilizing a plurality of groups of through holes 2242 opened on the surface of the adsorption tube 2241, the limiting cross bar 2182 or the movable cross bar 2186 entering into the recovery chamber 223 are subjected to adsorption treatment at different positions on the surface, thereby reducing the residual crystals on the surface of the stirring cross bar and reducing the labor intensity of manually recovering the crystals.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
