DETAILED DESCRIPTION

[0021] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0022] Embodiment: A highly efficient calcium hydroxide air separation device, see Figure 1-Figure 5As shown, it includes an air separation bin 3, a bracket 1, a lower hopper 2, a gas recovery bin 31, a collecting frame 8, a first handle 81, a slope 7, a fan 13, an activated carbon adsorption plate 12, a second handle 121, a filter 14 and an observation window 15. The air separation bin 3 is connected to a left-right symmetrical bracket 1 by means of bolts. The upper part of the air separation bin 3 is connected to a lower hopper 2 for placing calcium hydroxide. The upper part of the air separation bin 3 is connected to gas recovery bins 31 distributed on the left and right by means of bolts. The gas recovery bin 31 is connected to the air separation bin 3. The bottom of the gas recovery bin 31 is in contact with the top of the bracket 1. Four collecting frames 8 evenly spaced are slidably connected to the lower part of the air separation bin 3. The collecting frames 8 on the left and right sides are used to collect calcium hydroxide with large particles, and the two collecting frames 8 on the middle side are used to collect calcium hydroxide with small particles. The front side of the collecting frame 8 is connected to a first handle 81 for auxiliary pulling by means of bolts. At least six slopes 7 are provided in the lower part of the air separation bin 3. The slope 7 is placed above the collecting frame 8 for guiding materials. The inside of the gas recovery bin 31 is connected with a fan 13 by bolts, and an activated carbon adsorption plate 12 for filtering the airflow is slidably connected inside the gas recovery bin 31. The front of the activated carbon adsorption plate 12 is connected with a second handle 121 for assisting pulling. The lower part of the gas recovery bin 31 is connected with a filter screen 14 for filtering the airflow, and the upper part of the air separation bin 3 is embedded with an observation window 15 for viewing the situation. By starting the fan 13, the gas is blown into the air separation bin 3 to generate air. The air-selected calcium hydroxide also includes an air pump 9, an air extraction pipe 10 and an air supply pipe 11. The lower part of the lower hopper 2 is connected to the symmetrically distributed air pump 9 by bolts. The lower part of the air pump 9 is connected to the upper part of the air selection bin 3 and communicated with the air extraction pipe 10. The upper part of the air pump 9 is connected to the upper part of the gas recovery bin 31 and communicated with the air supply pipe 11. By starting the air pump 9, the air extraction pipe 10 draws the airflow inside the air selection bin 3, and the air pump 9 pumps the airflow into the air supply pipe 11 and discharges it back into the gas recovery bin 31.

[0023] See also Figure 1 and Figure 3 As shown, it also includes a driving motor 4, a discharge impeller 6 and a pulley assembly 5. The left front part of the discharge hopper 2 is connected to the driving motor 4 by bolts. The lower part of the discharge hopper 2 is rotatably connected to the discharge impellers 6 distributed on the left and right. The discharge impellers 6 are used to break up and disperse the calcium hydroxide. The pulley assembly 5 is connected between the two discharge impellers 6. The output shaft of the driving motor 4 is connected to the left part of the pulley assembly 5. The pulley assembly 5 is rotated by the driving motor 4, so that the discharge impeller 6 rotates to break up and disperse the calcium hydroxide.

[0024] First, the staff pours an appropriate amount of calcium hydroxide to be air-selected into the discharge hopper 2 so that the calcium hydroxide contacts the discharge impeller 6, and then covers the discharge hopper 2 with a cover plate so that the calcium hydroxide is discharged in a closed space. Then, the fan 13 is started, and the speed of the fan 13 is adjusted according to the degree of air selection of the calcium hydroxide. The fan 13 rotates to blow wind into the upper part of the air selection bin 3 through the gas recovery bin 31 to generate airflow, and then the drive motor 4 is started. The output shaft of the drive motor 4 rotates to drive the pulley assembly 5 to rotate, so that the pulley assembly 5 drives the two discharge impellers 6 to rotate at the same time, and then the calcium hydroxide is dispersed and broken up and transported to the air selection bin 3, so as to achieve a uniform discharge effect. The filter 14 plays a filtering role to prevent calcium hydroxide from entering the gas recovery bin 31. The transported calcium hydroxide is air-selected by the airflow. During the air selection process, large-sized calcium hydroxide falls directly downward. The small-sized calcium hydroxide particles are blown toward the middle by the airflow and then fall into the two collecting frames 8 on the middle side, thereby realizing the air selection of calcium hydroxide. The inclined surface 7 plays a guiding role, and the large-sized and small-sized calcium hydroxide particles are respectively introduced into the corresponding collecting frames 8, and then the air pump 9 is started. The air pump 9 operates to make the exhaust pipe 10 extract the airflow in the upper part of the air selection bin 3, and then pump the airflow into the air supply pipe 11 and discharge it into the gas recovery bin 31. The airflow in the gas recovery bin 31 is blown into the upper part of the air selection bin 3 again by the fan 13, so as to achieve the purpose of closed-loop circulation of the airflow and avoid the discharge of calcium hydroxide powder carried by the airflow. During the closed-loop circulation of the airflow, the activated carbon adsorption plate 12 filters the airflow, so that the calcium hydroxide powder remaining in the airflow stays on the activated carbon adsorption plate 12, which is convenient for taking out the activated carbon adsorption plate 12 to collect calcium hydroxide later.

[0025] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
