[0023] In an embodiment of the present utility model, as Figures 1 to 3As shown in the figure, a phosphoric acid waste liquid recovery device is provided, including a device main body 10. The device main body 10 is provided with a mixing barrel 11. A footrest 12 for supporting the mixing barrel is provided at the bottom of the mixing barrel 10. A controller 13 with a display screen is provided on the front side of the mixing barrel 11. A driving device 13 is arranged at the center of the top of the mixing barrel 11. The output shaft of this driving device 13 penetrates the top of the mixing barrel 11 and extends into its cavity 114. And inside the cavity 114, a rotating rod 131 is connected to the output shaft of the driving device 13. Stirring paddles for stirring the mixed liquid are provided on the rotating rod 131.

[0024] Preferably, the stirring paddles include a first stirring paddle 132 and a second stirring paddle 133. In this embodiment, the number of the first stirring paddles 132 is two, which are respectively arranged in the middle and upper part of the rotating rod 131. The number of the second stirring paddles 133 is one, which is arranged at the bottom end of the rotating rod 131. And engaging parts 1321 are provided on the stirring paddles. The stirring paddles are connected to the rotating rod 131 through these engaging parts 1321. With such a setting, the liquid in the cavity 114 of the mixing barrel 11 is fully stirred in the vertical direction.

[0025] More specifically, the first stirring paddle 132 is provided with a first paddle blade 1322, and one end of the first paddle blade 1322 is fixedly connected to its engaging part 1321; the second stirring paddle 133 is provided with a second paddle blade 1332, and one end of the second paddle blade 1332 is fixedly connected to its engaging part 1321. The setting of the two kinds of stirring paddles improves the stirring effect at different positions in the vertical direction.

[0026] Preferably, the shape of the first paddle blade 1322 is set as a "V" shape, and it is symmetrically bent backward from the center. The first paddle blade 1322 is fixedly connected to the engaging part 1321 of the first stirring paddle 132 at an angle non-perpendicular to the horizontal plane, so that the stirring paddle is more likely to cut into the liquid for stirring, generating a stirring eddy current and accelerating the stirring; the second paddle blade 1332 is set as a parallelogram and is fixedly connected to the engaging part 1321 of the second stirring paddle 133 at an angle perpendicular to the horizontal plane, rotating with a greater resistance to improve the stirring effect of the bottom liquid.

[0027] On both sides of the driving device 13, a phosphoric acid inlet pipe 112 and an alkali liquid inlet pipe 113 are respectively provided on the mixing barrel 11. The phosphoric acid inlet pipe 112 and the alkali liquid inlet pipe 113 are both connected to the mixing barrel 11 through flanges 116, making their pipeline connections firm and with good sealing performance; and a split-flow liquid outlet pipe 115 penetrating the bottom of the barrel is connected to the bottom of the mixing barrel 11. The liquid outlet pipe 115 is a tee pipe. Its left side is a phosphoric acid recovery pipe 1151, and its right side is a discharge pipe 1152. And regulating valves 117 for controlling the flow rate of the liquid are provided on both the phosphoric acid recovery pipe 1151 and the discharge pipe 1152, facilitating the control of the outflow of the liquid in the mixing barrel 11.

[0028] On both sides of the bottom of the cavity 114, there is a heating device 15 electrically connected to the controller 111. The controller controls the operation of the heating device 15 to adjust the temperature of the liquid in the mixing barrel 11. And a PH sensor 14 is provided at the bottom of the cavity 114. This sensor is also electrically connected to the controller 111. The PH sensor 14 detects the pH value of the liquid in the mixing barrel 11 and is displayed on the screen of the controller 111.

[0029] Working principle: Start the controller 111, and let the phosphoric acid waste liquid flow into the mixing barrel from the phosphoric acid inlet pipe 112. The PH sensor 14 in the mixing barrel 11 detects the PH value of the phosphoric acid waste liquid. If it meets the recovery standard, open the phosphoric acid recovery pipe 1151 at the bottom of the mixing barrel 11 for recycling; if the PH value does not meet the standard, open the lye inlet pipe 113 to pour in lye to react with the phosphoric acid waste liquid. At the same time, use the controller 111 to start the heating device 15 and the stirring paddle to increase the temperature for stirring. After the mixing reaction is over, check the detected PH value again. If it does not meet the standard, continue to drain in lye for reaction. If it meets the standard, open the discharge pipe 1152 to discharge the treated phosphoric acid waste liquid.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
