Working principle: When using, first put the pharmaceutical wastewater into the separation tank 2. The flocculant in the separation tank 2 reacts with the wastewater, which can aggregate the particulate matter and organic matter in the wastewater into large sediments, and then through the first water pump 4 The wastewater containing sediment is pumped into the centrifugal drum 8. At this time, the suction pipe valve 7 is controlled to close so that the wastewater remains in the centrifugal drum 8. Then the centrifugal motor 11 is controlled to run to drive the driving bevel gear 12 to rotate. The driving bevel gear 12 The driven bevel gear 10 is driven to rotate, and the driven bevel gear 10 drives the drum connecting pipe 9 and the centrifugal drum 8 to rotate. The centrifugal drum 8 drives a plurality of centrifugal push plates 13 on the inside to rotate. The rotation of the centrifugal push plates 13 can push the centrifugal drum. The wastewater inside the drum 8 rotates. As the rotation speed of the centrifugal drum 8 increases, the rotation speed of the wastewater in it also increases. The density of the sediment in the wastewater is greater than the density of water. Under the action of centrifugal force, the suspended solids with higher density are It will move toward the inner wall of the centrifugal drum 8, and the water with lower density gathers at the center of the centrifugal drum 8, so that water and sediment can be quickly separated without the need for gravity sedimentation, which greatly improves the water efficiency. and the separation speed of the sediment, and the centrifugal force on the sediment in the waste water can be increased by increasing the rotation speed of the centrifugal drum 8, thereby helping to improve the separation effect of the sediment and reducing the sediment content in the waste water to a higher level. Low.

The sediment continues to move around under the action of centrifugal force, and finally flows into the inside of the collection circle 302 of the sediment discharge mechanism through the multiple sediment outlets 14 on the outside of the centrifugal drum 8. At the same time, the sludge pump 304 of the sediment discharge mechanism can operate. The sediment inside the collection ring 302 is sucked into the inside of the impurity collection pipe 303, and finally discharged outward through the discharge pipe 305, which plays the role of automatically separating the sediment, improves the separation effect of wastewater, and can prevent the sediment from flowing back into the wastewater. In the water, ensure that the water at the center of the centrifugal drum 8 is clean.

At the same time, the second water pump 5 of the liquid extraction mechanism is controlled to operate, and the suction pipe valve 7 is controlled to open. The second water pump 5 pumps the inside of the clean water suction pipe 6, the central cannula 101, and the collection tube 103 into a negative pressure state, so that the centrifugal drum 8 can be The water located in the center flows into the inside of the collection tube 103 through the plurality of rectangular filter holes 105, and then flows into the inside of the chemical treatment tank 1 through the central cannula 101, the clean water suction pipe 6, and the second water pump 5. The inside of the chemical treatment tank 1 The reaction reagents can further chemically treat the separated water to remove toxic substances in the water so that the water can be recycled again. The multiple rectangular filter holes 105 only allow water to pass into the inside of the collection tube 103, and the density of the water is small. The unseparated small particle suspended solids will be blocked outside the first blocking plate 104, which can prevent the small particle suspended solids from flowing into the inside of the chemical treatment tank 1 along with the water, further improving the quality of wastewater treatment.

In order to prevent the rectangular filter hole 105 from being blocked by small suspended particles, the clogging motor 106 that controls the clogging mechanism is operated to drive the chute turntable 107 to rotate. The first chute 108 and the second chute 109 on the upper surface of the chute turntable 107 can be connected with each other. A plurality of sliding pins 113 are rollingly connected. Each time the chute turntable 107 rotates once, the plurality of sliding pins 113 can alternately slide from the inside of the first chute 108 to the inside of the second chute 109. When the sliding pins 113 slide in When reaching the inside of the second chute 109, the corresponding cleaning needle fixing plate 111 can be pushed to move toward the edge of the collection tube 103. This cleaning needle fixing plate 111 drives a plurality of cleaning needles 112 on one side to be inserted into each corresponding cleaning needle fixing plate 111. into the rectangular filter hole 105, and then extends to the outside of the collection tube 103. When the cleaning needle 112 passes through the rectangular filter hole 105, it can push out the suspended matter blocked inside the rectangular filter hole 105, which plays a role in clearing the blockage and keeps multiple The inside of the rectangular filter hole 105 is unobstructed, so that water can flow into the inside of the collection tube 103 through the rectangular filter hole 105 more smoothly, improving the separation effect. At the same time, the anti-teeth 114 at the end of the cleaning needle 112 can increase the distance between the suspended solids and the cleaning needle 112 The friction force at the end can prevent the suspended matter from falling off the end of the cleaning needle 112 and prevent the suspended matter from returning to the water.

The cleaning needle fixing plate 111 and the cleaning needle 112 push the suspended matter to continue to move. At the same time, the cleaning needle fixing plate 111 pushes the sliding rod 110 and the cleaning needle 112 to move synchronously. The sliding rod 110 will drive the two one-way pushing mechanisms at one end to the collection shell 201 synchronously. The two rotating collars 212 of the one-way push mechanism can only rotate at a certain angle in one direction under the limiting action of the two collar limit blocks 214 and the two fixed limit blocks 215. The two torsion springs Under the action of the elastic force of 213, a certain twisting moment can be given to the two rotating collars 212, so that the collar limit block 214 at the upper end of the rotating collar 212 is closely attached to one side of the fixed limit block 215. When the sliding rod 110 drives the single When the pushing mechanism moves toward the inside of the collection shell 201, the two pushing rollers 217 will contact the two wedge-shaped blocks 209 of the opening and closing control mechanism at the corresponding positions. Under the guidance of the inclined surfaces at one end of the two wedge-shaped blocks 209, the two pushing rollers 217 will The push roller 217 pushes the two wedge-shaped blocks 209 to move in opposite directions to both sides respectively, thereby driving the two opening and closing levers 208 to move in opposite directions and separate from each other, and compress the arc-shaped elastic pieces 207 on both sides, and the two opening and closing levers 208 drive the two opening and closing levers 208 respectively. The two second blocking plates 203 of the same height move in opposite directions, causing the multiple collection rectangular openings 204 inside the two second blocking plates 203 to overlap, as shown in Figure 9 of the specification. At the same time, multiple cleaning needles 112 It is moving, just extending into the inside of the collection shell 201 through the overlapping collection rectangular opening 204 at the corresponding position, and at the same time, the debris adhered to the end of the cleaning needle 112 is brought into the inside of the collection shell 201. As the roller rod 216 continues to move, when After the two pushing rollers 217 are separated from the two wedge-shaped blocks 209, the arc-shaped elastic pieces 207 on both sides release the elastic force to push the two opening and closing rods 208 to merge, thereby driving the two second blocking plates 203 to move in the opposite direction, causing the two second blocking plates 203 to move in opposite directions. The collection rectangular openings 204 inside the blocking plate 203 are staggered, and the collection rectangular openings 204 inside the two second blocking plates 203 are staggered to each other so that both sides of the cleaning needle 112 inside can be clamped.

As the arc-shaped elastic piece 207 of the clearing mechanism continues to rotate, when the sliding pin 113 at the corresponding position slides into the inside of the first chute 108 from the second chute 109, the cleaning needle fixing plate 111, the cleaning needle 112, The sliding rod 110 moves reversely to reset.
