Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, in particular to a wastewater purification treatment device for medicine production. BACKGROUND

[0002] The medicine production wastewater refers to the sewage containing a large amount of harmful substances such as chemical substances, herbal fibers and gelatinous substances generated during the manufacture of medicines, and the direct discharge of the wastewater will cause great harm to the environment and human body. Therefore, the wastewater needs to be purified before being discharged. In the commonly used wastewater purification method, the separation of floating substances needs to be realized by means of a gas floatation machine. In the use of the traditional gas floatation machine, air is discharged into the wastewater by a gas pump and forms air bubbles in the water, so that the floating substances can be adsorbed by the surface layer of the air bubbles, thereby realizing the aggregation and floating separation of the floating substances. However, due to the fact that the air bubbles discharged from the air discharge pipe are relatively aggregated and have a large volume, the air bubbles cannot be distributed in a large area inside the gas floatation machine, which leads to the fact that the air bubbles float too fast and cannot fully adsorb the floating substances in the wastewater, thereby affecting the quality of wastewater treatment.

The present embodiment is written in a progressive manner.

[0032] As Figures 1 to 5 shown, the wastewater purification treatment device for pharmaceutical production of the present application comprises:

[0034] The air distribution mechanism is composed of a plurality of air feeding groove plates 6;

[0035] The water inlet pipe 3 is communicated on the baffle disc 2 on one side of the purification cylinder 1, the overflow pipe 4 and the through hole 5 are arranged on the baffle disc 2 on the other side of the purification cylinder 1, the overflow pipe 4 is located above the through hole 5, the plurality of air feeding groove plates 6 are annularly distributed on the circumferential inner wall of the purification cylinder 1, the cross section shape of the air feeding groove plate 6 is arc-shaped, the axis of the air feeding groove plate 6 is parallel to the axis of the purification cylinder 1, the two ends of the air feeding groove plate 6 are blocked, the opening of the air feeding groove plate 6 is located on the outer wall of the air feeding groove plate 6, and the direction of the opening of the air feeding groove plate 6 is along the tangent direction of the air feeding groove plate 6 following the circumferential movement of the purification cylinder 1.

[0036] Specifically, the middle and lower part of the purification cylinder 1 stores wastewater, the upper part of the inside of the purification cylinder 1 is filled with air, the purification cylinder 1 moves circumferentially along the axis thereof, the plurality of air feeding groove plates 6 on the purification cylinder 1 move circumferentially synchronously, so that when the opening of the air feeding groove plate 6 faces downward and enters the water, the air in the air feeding groove plate 6 cannot be discharged and carried into the water, with the continuous movement of the air feeding groove plate 6, the angle of the opening of the air feeding groove plate 6 changes continuously, at this time, the air in the air feeding groove plate 6 is continuously discharged into the water through the edge position of the opening of the air feeding groove plate 6, that is, the air feeding groove plate 6 continuously performs air dispersing work while moving in an arc shape following the purification cylinder 1, and the wastewater in the purification cylinder 1 is continuously supplemented into the air feeding groove plate 6, due to the action of water pressure and the continuous change of the inclination angle of the air feeding groove plate 6, the volume of the bubbles discharged by the edge position of the air feeding groove plate 6 is small, so that the air feeding groove plate 6 realizes continuous movement and uniform air dispersing in the wastewater, so that the bubbles are uniformly and widely distributed at the bottom of the wastewater, and the volume of the bubbles is small, thereby realizing the air floatation separation of impurities in the wastewater, the baffle disc 2 supports the purification cylinder 1 and blocks the opening of the purification cylinder 1, and air can flow between the inside and outside of the purification cylinder 1 through the overflow pipe 4.

[0037] In use, the wastewater is introduced into the purification cylinder 1 through the baffle disc 2, the purification cylinder 1 is rotated, the plurality of air feeding groove plates 6 on the purification cylinder 1 are synchronously rotated, the air in the air feeding groove plate 6 is pressed into the water, and with the continuous change of the angle of the arc movement of the air feeding groove plate 6, the direction of the opening of the air feeding groove plate 6 changes continuously, at this time, the air in the air feeding groove plate 6 is continuously discharged into the water through the edge position of the opening of the air feeding groove plate 6 and forms bubbles in the water, due to the action of water pressure and the extrusion of the edge position of the opening of the air feeding groove plate 6 on the bubbles, the volume of the generated bubbles is avoided to be too large, so that the air feeding groove plate 6 can arrange a large number of bubbles in the wastewater, and the volume of the bubbles is small, the bubbles float in the wastewater and adsorb the floating impurities in the wastewater, thereby realizing the purification treatment of the wastewater, with the continuous pressing of the air into the water by the plurality of air feeding groove plates 6, thereby realizing the continuous air floatation purification treatment of the wastewater, the purified wastewater flows toward the water inlet pipe 3 position and is discharged through the water inlet pipe 3, at the same time, the water inlet pipe 3 can limit the amount of wastewater stored in the purification cylinder 1, and the setting of the overflow pipe 4 can make the air flow between the inside and outside of the purification cylinder 1, thereby supplementing the air in the inside of the purification cylinder 1.

[0038] Since the distribution area of the air bubbles discharged by the air delivery groove plate 6 is related to the opening angle and size of the air delivery groove plate 6, the caliber of the opening of the air delivery groove plate 6 should not exceed one fourth of the circle in which the cross section of the air delivery groove plate 6 is located, and the direction of the opening of the air delivery groove plate 6 should be along the tangent direction of the circumferential movement, so that the air delivery groove plate 6 can always realize air distribution after entering the wastewater, as the opening angle of the air delivery groove plate 6 changes, thereby increasing the air bubble distribution area and the air storage capacity inside the air delivery groove plate 6, and avoiding the air inside the air delivery groove plate 6 being exhausted when the air delivery groove plate 6 does not move to the end of the stroke in the wastewater due to the too large opening angle of the air delivery groove plate 6.

[0039] By using the air delivery groove plate 6 to carry air and press it into the wastewater, a large number of air bubbles can be formed in the wastewater, so that the floating impurities in the wastewater can be separated and treated by air floatation, and the purification of the wastewater can be realized. Since the air delivery groove plate 6 follows the circumferential movement of the purification cylinder 1, the air delivery groove plate 6 can realize continuous air exhaust as the opening angle on it changes, that is, the air delivery groove plate 6 is always in the air exhaust state during the movement in the wastewater, so that the air bubbles can be distributed in a large area in the wastewater. Since the opening angle of the air delivery groove plate 6 gradually changes, combined with the effect of water pressure on air, the volume of the air bubbles discharged at the opening position of the air delivery groove plate 6 is small, so that the small air bubbles can be distributed in a large area in the wastewater, thereby effectively increasing the adsorption amount of impurities and facilitating the overall air floatation treatment of the wastewater, and improving the wastewater treatment effect.
