DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1, refer to Figures 1-4, A pharmaceutical tablet waste treatment device, including a wastewater treatment tank 2, an upper cover 1, a base 5 and a support plate 4: A sleeve 22 is installed at the bottom of the wastewater treatment tank 2, the inside of the sleeve 22 is connected to the inside of the through hole 19, and a drain pipe 6 is also provided on the sleeve 22.

[0026] The wastewater treatment tank 2 is filled with hydrogen peroxide reagent and magnetic catalyst particles. The magnetic catalyst particles are specifically Fe 3 O 4 @TiO 2 catalyst particles. A fixing seat 11 is installed at the center of the bottom of the wastewater treatment tank 2, and the fixing seat 11 is arranged in a tapered shape with a narrow upper part and a wide lower part. A through hole 19 is vertically opened inside the fixing seat 11. A motor 7 is installed on the upper part of the base 5. A rotating shaft 17 is arranged inside the through hole 19, and the bottom of the rotating shaft 17 is connected to the upper part of the output shaft of the motor 7. The top of the rotating shaft 17 extends to the outside of the through hole 19. An auger 21 is installed on the outside of the rotating shaft 17, and the auger 21 cooperates with the through hole 19.

[0027] A plurality of annular protrusions 12 are arranged on the upper end of the outside of the fixing seat 11. When the reagent and wastewater are injected into the wastewater treatment tank 2, the liquid level is located below the height where the protrusions 12 are located. A plurality of second slot holes 10 are arranged in an annular array at the lower end of the fixing seat 11, and the second slot holes 10 communicate with the through hole 19.

[0028] By combining Fe 3 O 4 @TiO 2 catalyst with hydrogen peroxide, on the one hand, it can oxidize antibiotics and hormone substances in pharmaceutical wastewater. At the same time, Fe 3 O 4 @TiO 2 catalyst has an adsorption effect, mainly used for adsorbing and removing heavy metal ions and organic pollutants in wastewater. Its adsorption performance stems from its high specific surface area and surface active sites. However, the pharmaceutical wastewater may also contain macromolecular proteins. When protein molecules cover the active sites outside the catalyst particles, the adsorption effect of the catalyst will decrease. Therefore, it is necessary to keep the catalyst particles in motion in the wastewater, which can avoid the accumulation of protein molecules on the outside of the catalyst particles. At the same time, if the stirring method is used for treatment, in the case of slow speed, these catalyst particles will still aggregate at the bottom of the container. In the case of rapid stirring, the shear force generated by stirring may cause the interface separation between the Fe 3 O 4 magnetic core and the TiO 2 outer shell.

[0029] For this reason, a fixed seat 11 with a conical shape is arranged in the middle of the inner side of the wastewater treatment tank 2. The through hole 19 vertically arranged in the inner side and the second slot hole 10 opened at the bottom serve as the main paths for the circulating flow of catalyst particles. The catalyst particles in the wastewater will fall to the bottom position of the wastewater treatment tank 2 under the action of gravity. Since the cushion block 3 is recessed towards the middle, these catalyst particles will enter from the second slot hole 10 at the bottom of the fixed seat 11. When the catalyst particles enter the inner side of the through hole 19, the motor 7 always drives the auger 21 to rotate, conveying these catalyst particles upwards until some of the catalyst particles leave the through hole 19 and roll down from the upper end of the fixed seat 11. The rolled catalyst particles re-enter the through hole 19 from the bottom again, repeating in a cycle. The catalyst particles are in continuous motion, which can fully adsorb the substances in the wastewater and at the same time prevent the problem that macromolecular proteins cover the adsorption sites on the outside of the catalyst.

[0030] When the catalyst particles roll down from the upper end of the fixed seat 11, there are multiple annular protrusions 12 arranged at the upper end position of the fixed seat 11. When these catalyst particles pass over the protrusions 12, there will be a bumpy situation, and the protein molecules that have covered the particle surface will be separated by means of this movement trend.

[0031] Example 2, refer to Figure 3 , the difference between this embodiment and Embodiment 1 is that an annular plate 8 is rotatably arranged at the lower outer end of the fixed seat 11. A plurality of first slot holes 9 are opened on the annular plate 8. The first slot holes 9 correspond to the second slot holes 10 one by one, and the inner side of the second slot hole 10 is inclined. A cushion block 3 is arranged at the bottom of the wastewater treatment tank 2. The cushion block 3 is annularly arranged, and the middle of the cushion block 3 is recessed downward. The lower edge of the cushion block 3 corresponds to the positions of the first slot holes 9 and the second slot holes 10.

[0032] When the chemical treatment of the wastewater is completely finished, it is necessary to recover these catalyst particles. The traditional method is to collect them by using a magnet to adsorb these particles, but the internal structure of the equipment is complex and the magnet cannot reach every area, so it is relatively difficult to collect.

[0033] For this reason, when the chemical treatment of the wastewater is finished, at this time, open the upper cover 1 and use a tool, such as a rod, to adjust the position of the annular plate 8. When the first slot holes 9 outside the annular plate 8 do not coincide with the second slot holes 10, stop rotating the annular plate 8. At this time, continue to keep the motor 7 running. When the catalyst particles do not roll out from the through hole 19, stop the rotation of the motor 7. Then use a magnet to collect the catalyst particles scattered between the cushion block 3 and the fixed seat 11. After the collection is completed, rotate the annular plate 8 again so that there is an overlapping part between the first slot holes 9 and the second slot holes 19, start the motor 7 to reverse, and open the valve on the drain pipe 6 to discharge the treated wastewater.

[0034] Example 3, referring to Figures 5-6 , the difference between this example and Example 1 and Example 2 is that a plurality of notches 16 are distributed in an annular array at the upper end of the fixed seat 11, and an auxiliary material scattering structure is arranged at the upper end outside the fixed seat 11. The auxiliary material scattering structure includes a connecting rod 15, a straight plate 18 and a channel 23.

[0035] The channel 23 is opened in the middle position at the upper end of the straight plate 18 along the long side direction of the straight plate 18. One end of the channel 23 is in close contact with the outside of the notch 16, and the other end of the channel 23 is fixed at the upper part of the rotating shaft 17 through the connecting rod 15. A plurality of parallel square holes 20 are opened in the channel 23, and the square holes 20 are arranged along the short side direction of the channel 23. The sizes of the multiple square holes 20 gradually decrease in the direction close to the fixed seat 11.

[0036] A rotating rod 14 is connected to the lower end of the straight plate 18, and a rotating blade 13 is fixedly installed at the bottom of the rotating rod 14, and the bottom of the rotating blade 13 extends below the wastewater liquid level.

[0037] In order to expand the moving range of the catalyst particles in the wastewater treatment tank 2, a straight plate 18 is arranged at the upper end of the rotating shaft 17 through the connecting rod 15. A channel 23 for the catalyst particles to move is arranged at the upper end of the straight plate 18, and one end of the channel 23 matches the position of the notch 16. When the straight plate 18 is indirectly driven by the rotating shaft 17 to rotate, when the positions of the channel 23 and the notch 16 are aligned, part of the catalyst particles will be transferred from the notch 16 to the channel 23. As the straight plate 18 rotates, the catalyst particles in these channels 23 will move towards the distal end of the straight plate 18. At the same time, square holes 20 with different sizes are arranged in the channel 23. Therefore, the catalyst particles will gradually fall during the movement towards the distal end of the channel 23, realizing falling at different positions, avoiding the blockage of the channel 23, and at the same time, the protein molecules covering the outer surface of the catalyst particles can also be shaken off during the contact and collision with the square holes 20.

[0038] Since pharmaceutical wastewater contains a large amount of organic matter, the existence of these organic matters will cause emulsified oil to form on the surface of the wastewater. There are two main types of these oils, one is oil-in-water, and the other is water-in-oil. No matter which type of emulsified oil, it will accumulate on the surface of the wastewater. When these emulsified oils accumulate to a certain thickness on the wastewater surface, it will make the falling catalyst particles unable to complete the transfer smoothly.

[0039] To this end, it is necessary to prevent the thickness of the emulsified grease on the surface of the wastewater from being too thick, and connect the rotating blade 13 through the rotating rod 14 at the lower position near the far end of the straight plate 18. When the straight plate 18 moves, the rotating blade 13 at the lower end will move together. During the movement, the rotating blade 13 avoids contact with the grease, and then through the moving effect of the rotating blade 13, the problem of too thick grease on the surface is suppressed, so that the catalyst particles can smoothly return to the pad 3 for circulation transfer.

[0040] The working principle of the device is: Use Fe 3 O 4 @TiO 2 The catalyst combined with hydrogen peroxide can oxidize antibiotics and hormones in pharmaceutical wastewater, while Fe 3 O 4 @TiO 2 Catalysts have an adsorption function and are mainly used to adsorb and remove heavy metal ions and organic pollutants in wastewater. Their adsorption performance comes from their high specific surface area and surface active sites. However, pharmaceutical wastewater may also contain large molecular proteins. When protein molecules cover the active sites on the outside of the catalyst particles, the adsorption effect of the catalyst will decrease. Therefore, the catalyst particles need to be in motion in the wastewater to avoid the accumulation of protein molecules on the outside of the catalyst particles. At the same time, if the treatment is carried out by stirring, these catalyst particles will still gather at the bottom of the container under slow conditions. Under fast stirring, the shear force generated by stirring may cause Fe 3 O 4 Magnetic core and TiO 2 The interface of the shell is separated.

[0041] To this end, a conical fixed seat 11 is arranged in the middle of the inner side of the wastewater treatment box 2, and a through hole 19 vertically arranged in the inner side and a second slot 10 opened at the bottom serve as the main path for the circulation of catalyst particles. The catalyst particles in the wastewater will fall to the bottom of the wastewater treatment box 2 under the action of gravity. Since the pad 3 is recessed toward the middle, these catalyst particles will enter from the second slot 10 at the bottom of the fixed seat 11. After the catalyst particles enter the inner side of the through hole 19, the motor 7 drives the auger 21 to operate and transport the catalyst particles upward until some of the catalyst particles leave the through hole 19 and roll down from the upper end of the fixed seat 11. The rolled catalyst particles re-enter the through hole 19 from the bottom, and the cycle is repeated. The catalyst particles are in constant motion, which can fully adsorb the substances in the wastewater while preventing the problem of large molecular proteins covering the adsorption sites outside the catalyst.

[0042] When the catalyst particles roll down from the upper end of the fixed seat 11, there are multiple annular protrusions 12 at the upper end position of the fixed seat 11. When these catalyst particles pass over the protrusions 12, there will be a bumpy situation, and the protein molecules that have covered the particle surface will be separated by means of this movement trend.

[0043] After the chemical treatment of the wastewater is completely finished, these catalyst particles need to be recovered. Conventionally, a magnet is used to adsorb and collect these particles, but the internal structure of the equipment is complex, and the magnet cannot reach every area, so it is relatively difficult to collect them.

[0044] Therefore, after the chemical treatment of the wastewater is finished, at this time, open the upper cover 1, and use tools such as a rod to adjust the position of the annular plate 8. When the first slot 9 outside the annular plate 8 and the second slot 10 do not overlap with each other, stop rotating the annular plate 8. At this time, continue to keep the motor 7 running. When the catalyst particles do not roll out from the through hole 19, stop the rotation of the motor 7. Then use a magnet to collect the catalyst particles scattered between the cushion block 3 and the fixed seat 11. After the collection is completed, rotate the annular plate 8 again so that there is an overlapping part between the first slot 9 and the second slot 19. Start the reverse rotation of the motor 7 and open the valve on the drain pipe 6 to discharge the treated wastewater.

[0045] In order to expand the moving range of the catalyst particles in the wastewater treatment tank 2, a straight plate 18 is arranged at the upper end of the rotating shaft 17 through a connecting rod 15. There is a channel 23 for the catalyst particles to move at the upper end of the straight plate 18, and one end of the channel 23 matches the position of the notch 16. When the straight plate 18 is indirectly driven by the rotating shaft 17 to rotate, when the positions of the channel 23 and the notch 16 are aligned, some of the catalyst particles will transfer from the notch 16 to the channel 23. As the straight plate 18 rotates, these catalyst particles in the channel 23 will move towards the distal end of the straight plate 18. At the same time, square holes 20 of different sizes are arranged in the channel 23. Therefore, during the movement of the catalyst particles towards the distal end of the channel 23, they will gradually fall, realizing falling at different positions, avoiding the blockage of the channel 23, and at the same time, the protein molecules covering the outer surface of the catalyst particles can also be shaken off during the contact and collision with the square holes 20.

[0046] Since pharmaceutical wastewater contains a large amount of organic matter, the presence of these organic matters will cause emulsified grease to form on the surface of the wastewater. There are two main types of these greases, one is oil-in-water, and the other is water-in-oil. No matter which type of emulsified grease it is, it will accumulate on the surface of the wastewater. When these emulsified greases accumulate to a certain thickness on the surface of the wastewater, it will cause the falling catalyst particles to be unable to complete the transfer smoothly.

[0047] To this end, it is necessary to prevent the thickness of the emulsified grease on the surface of the wastewater from being too thick, and connect the rotating blade 13 through the rotating rod 14 at the lower position near the far end of the straight plate 18. When the straight plate 18 moves, the rotating blade 13 at the lower end will move together. During the movement, the rotating blade 13 avoids contact with the grease, and then through the moving effect of the rotating blade 13, the problem of too thick grease on the surface is suppressed, so that the catalyst particles can smoothly return to the pad 3 for circulation transfer.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
