[0002] Eye drop wastewater can be treated through a series of processes, such as sedimentation, filtration, biological treatment, and deep treatment, to remove most of the pollutants, so that the water quality meets certain standards and water resources can be recycled.

[0003] There are several problems with the existing wastewater treatment devices for eye drop preparation: 1. When the wastewater flow is too large or the flow rate is too fast, impurities will not be completely filtered out; 2. In addition, the proteins and polymers inside the eye drops need to be left standing for a period of time during the precipitation treatment. However, as the waste liquid accumulates, if the waste liquid still has a large flow and a fast flow rate, the subsequent influx of waste liquid will affect the former waste liquid that has been left standing, thereby increasing the standing time.

[0025] A wastewater treatment process for preparing eye drops comprises the following steps:

[0026] Step 1: The waste liquid with coagulant is fed into the feed pipe from the left end, and then passes through the No. 1 filter. At this time, the No. 1 filter will perform preliminary filtration on the impurities in the waste liquid, and finally enter the treatment tank;

[0027] Step 2: As the waste liquid accumulates in the treatment tank, it drives the buoyancy pad and the floating ring to move upward, and the top of the floating ring is connected to the curved block.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. By splicing and combining two No. 2 filters inside the feed pipe, the filtering effect on impurities in the wastewater inside the feed pipe is increased. At the same time, it also prevents incomplete filtration of the No. 1 filter due to excessive wastewater flow or too fast flow rate. In addition, it also uses the flow rate and flow rate of the waste liquid to adjust the extension and retraction of the No. 2 filter.

[0031] 2. As the multi-fold rod continues to move toward the processing tank, the triangular block fixedly connected to the other end thereof will pass through the frame rod and squeeze the flow limiting plate, wherein the contact surfaces between the two are both inclined surfaces, so the flow limiting plate will compress the return spring and insert into the feed pipe, thereby reducing the flow rate of the waste liquid and avoiding excessive flow rate and wear on the inner wall of the pipe.

[0032] 3. By moving the connecting tube upward and squeezing the elastic tube, the inner diameter of the elastic tube becomes narrower, thereby automatically reducing the amount of waste liquid flowing in as the waste liquid accumulates inside the treatment tank, so as to avoid the subsequent use of a larger inflow at the beginning and affecting the waste liquid that has already been settling.

[0033] 4. Drive the motor to reverse, then the blocking plate will move upward and stop the outflow of the remaining waste liquid in the treatment tank. Then the rope fixedly connected to the top of the rack will move to the left along the fixed pulley. At the same time, the discharge piece fixedly connected to the other end of the rope will pour the coagulant in the storage bin into the treatment tank, thereby playing a role in secondary sedimentation treatment of the waste liquid that has not been completely precipitated.

[0034] 5. When the residual waste liquid has flowed out, manually pull out the No. 1 plug plate. At this time, the sediment on the No. 1 plug plate and the screen will move downward from the left half of the waste pipe, thereby discharging the residual waste liquid and sediment through different channels.

[0049] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0050] See also Figures 1 to 13 The present invention provides a technical solution: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes a screening mechanism 2 for filtering insoluble impurities in wastewater, and a treatment tank 1 for storing and stacking wastewater, and the screening mechanism 2 is installed on the outside of the treatment tank 1;

[0051] A diversion mechanism 3 for diverting the waste liquid and impurities remaining at the bottom of the processing tank 1, the diversion mechanism 3 is installed at the bottom of the processing tank 1;

[0052] The packing mechanism 4 is used for draining and discharging the waste liquid after standing, and the packing mechanism 4 is installed on the outside of the treatment tank 1.

[0053] The screening mechanism 2 includes a connecting pipe 21, and leakproof laminates 22 are fixedly connected to the upper and lower sides of the connecting pipe 21, and one end of the leakproof laminate 22 away from the connecting pipe 21 is fixedly connected to the processing tank 1;

[0054] The top of the connecting tube 21 is fixedly connected to an elastic tube 23, the top of the elastic tube 23 is fixedly connected to a feed pipe 24, the top of the feed pipe 24 is fixedly connected to a rack rod 25, and the end of the rack rod 25 away from the feed pipe 24 is fixedly connected to the outside of the treatment tank 1; the waste liquid will enter the treatment tank 1 along the feed pipe 24, the elastic tube 23 and the connecting tube 21 in sequence, and the waste liquid will accumulate in the treatment tank 1 at this time, and as the waste liquid accumulates, the waste liquid will drive the buoyancy pad 34 to move upward, wherein the top of the buoyancy pad 34 is connected to the floating ring 32, so the floating ring 32 will move upward along the vertical rail 31, wherein the buoyancy pad 34 serves to increase the buoyancy of the floating ring 32. The top of the floating ring 32 is connected to the curved block 35. At this time, the curved block 35 will squeeze the connecting tube 21 upward, and then the connecting tube 21 will move upward along the processing tank 1, and compress and stretch the leak-proof laminates 22 fixedly connected to the upper and lower sides thereof, respectively. The leak-proof laminates 22 are elastic and play a role in preventing the waste liquid inside the processing tank 1 from overflowing. The upward movement of the connecting tube 21 will squeeze and compress the elastic tube 23 fixedly connected to the top thereof. At this time, the elastic tube 23 will bend and the space inside it will shrink. The shrinkage is the narrowing of the space inside the elastic tube 23, and it will also gradually narrow as the connecting tube 21 moves upward, thereby automatically reducing the amount of waste liquid flowing in as the waste liquid inside the processing tank 1 accumulates, so as to avoid the subsequent use of the larger inflow at the beginning and affecting the waste liquid that has been left to stand.

[0055] Inner grooves 28 are provided on both the upper and lower sides of the inner cavity of the feed pipe 24, and a No. 1 filter screen 29 is slidably adapted inside the inner groove 28. The outer side of the No. 1 filter screen 29 is fixedly connected to a multi-fold rod 20, and the outer side of the multi-fold rod 20 is fixedly connected to an elastic pad 201, and the elastic pad 201 is fixedly connected to the top of the feed pipe 24; the waste liquid with coagulant is added into the feed pipe 24 from the left end, wherein the coagulant is not mixed and stirred in the waste liquid for a long time before entering the feed pipe 24, but the waste liquid is added when it is ready to enter the feed pipe 24. If the flow rate of the waste liquid in the feed pipe 24 is too large or the flow rate is too high, the waste liquid in the feed pipe 24 will be put into the feed pipe 24. When it moves too fast, the waste liquid will impact the No. 1 filter screen 29, and the impacted No. 1 filter screen 29 will move inward along the inner groove 28 opened inside the feed pipe 24, wherein the outer side of the No. 1 filter screen 29 is connected to the multi-fold rod 20, so the multi-fold rod 20 will move toward the direction of the treatment tank 1 and stretch the elastic pad 201, wherein the elastic pad 201 is elastic and plays a role in resetting the multi-fold rod 20 and the No. 1 filter screen 29, and also plays a role in preventing the multi-fold rod 20 from causing gaps to open at the upper and lower ends of the feed pipe 24 during the movement, causing the waste liquid to overflow.

[0056] The top of the inner side of the multi-fold rod 20 is fixedly connected with a magnetic strip 202, and the end of the multi-fold rod 20 away from the first filter screen 29 is fixedly connected with a triangular block 203;

[0057] The top of the feed pipe 24 is plugged with a flow limiting plate 26, and the outer side of the flow limiting plate 26 is fixedly connected with a return spring 27, and the end of the return spring 27 away from the flow limiting plate 26 is fixedly connected to the feed pipe 24; as the multi-fold rod 20 continues to move toward the processing tank 1, the triangular block 203 fixedly connected to the other end thereof will pass through the frame rod 25 and squeeze the flow limiting plate 26, wherein the contact surface between the two is an inclined surface, so the flow limiting plate 26 will compress the return spring 27 and insert into the feed pipe 24, thereby reducing the flow rate of the waste liquid and avoiding the wear of the inner wall of the pipe due to excessive flow rate. In addition, excessive flow rate will also have a greater impact on the subsequent static state of the waste liquid.

[0058] The No. 2 filter screen 204 is inserted into the upper and lower sides of the feed pipe 24, the top of the No. 2 filter screen 204 is fixedly connected to a magnetic block 207, both sides of the No. 2 filter screen 204 are symmetrically connected to extension plates 205, the bottom of the extension plate 205 is fixedly connected to an elastic telescopic rod 206, and the end of the elastic telescopic rod 206 away from the extension plate 205 is fixedly connected to the feed pipe 24. The top of the inner side of the multi-fold rod 20 is fixedly connected with a magnetic strip 202. As the multi-fold rod 20 moves with the magnetic strip 202 toward the treatment tank 1, the distance between the magnetic strip 202 and the magnetic block 207 becomes closer and closer, and a repulsive force is generated between the two instead of no magnetic force. Then, the magnetic block 207 affected by the repulsive force will be inserted into the feed pipe 24 with the No. 2 filter screen 204 connected thereto. The splicing combination of the two No. 2 filter screens 204 inside the feed pipe 24 increases the filtering and processing effect on impurities in the wastewater inside the feed pipe 24, and also avoids incomplete filtration of the No. 1 filter screen 29 due to excessive wastewater flow or too fast flow rate. In addition, it also plays a role in self-regulating the extension and retraction of the No. 2 filter screen 204 by utilizing the flow rate and flow rate of the waste liquid. The two sides of the second filter screen 204 are symmetrically connected with extension pieces 205 , and the bottom of the extension pieces 205 is connected to the elastic telescopic rod 206 , wherein the elastic telescopic rod 206 plays a role in resetting the second filter screen 204 .

[0059] like Figure 7 , Figure 8 and Fig. 9 As shown, the flow dividing mechanism 3 includes a vertical rail 31, which is fixedly installed inside the processing tank 1, and a floating ring 32 is slidably adapted inside the vertical rail 31;

[0060] The buoyancy pad 34 is used to increase the buoyancy of the floating ring 32 and is fixedly connected to the bottom of the floating ring 32;

[0061] The counterweight block 33 is used for balancing the force of the floating ring 32 and is fixedly connected to the top of the floating ring 32;

[0062] A curved block 35 is fixedly connected to the top of the floating ring 32;

[0063] A waste pipe 36 is fixedly installed at the center of the bottom of the processing tank 1, and a partition 37 is fixedly connected to the center of the inner cavity of the waste pipe 36;

[0064] The first plug plate 38 is used for discharging the protein colloid and the polymer colloid, and is inserted through the outside of the waste pipe 36 and extends to the inside thereof;

[0065] A screen 39 is fixedly connected to one side of the partition 37 away from the first plug plate 38, and the screen 39 is fixedly connected to the inside of the waste pipe 36, wherein the screen 39 is used to screen the colloidal polymer in the residual waste liquid;

[0066] The second plug plate 30 is used for sealing the screen 39, and is inserted into the outside of the waste pipe 36 and extends to the inside thereof. When most of the waste liquid is discharged, the remaining waste liquid and sediment will accumulate at the bottom of the treatment tank 1. The operator manually pulls out the second plug plate 30 to expose the screen 39. At this time, the residual waste liquid will flow downward from the right half of the waste pipe 36 through the screen 39, and the sediment will stay on the screen 39 and the first plug plate 38. When the residual waste liquid flows out, the first plug plate 38 is manually pulled out. At this time, the sediment on the first plug plate 38 and the screen 39 will move downward from the left half of the waste pipe 36, thereby playing the role of discharging the residual waste liquid and sediment through different channels.

[0067] like Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the filling mechanism 4 includes a hollow frame 41, which is fixedly connected to the outside of the processing tank 1, and a notch 46 is opened on the side of the hollow frame 41 away from the processing tank 1, and a liquid outlet pipe 42 is fixedly connected to the outside of the liquid outlet pipe 42, and a reserved basket 43 is fixedly connected to the outside of the reserved basket 43, and an irradiation light 44 is fixedly installed on the outside of the reserved basket 43, and a sensor 45 is fixedly installed on the top of the reserved basket 43;

[0068] A No. 3 filter screen 47 is fixedly connected to the inside of the hollow frame 41, and plugging plates 48 are inserted at the upper and lower ends of the hollow frame 41. The surface of the plugging plate 48 is provided with a perforation 49, and a rack 40 is fixedly connected to the outside of the plugging plate 48. A gear 401 is meshed and driven on the outside of the rack 40. The gear 401 is rotatably connected to a bracket 402 through a rotating shaft, wherein the rotating shaft is connected to a motor 403 through a coupling, and the motor 403 is fixedly connected to the outside of the bracket 402, and the bracket 402 is fixedly connected to the outside of the hollow frame 41; when the waste liquid has been standing in the treatment tank 1, the protein colloid and polymer colloid precipitated by the coagulant will be at the bottom of the inner cavity of the treatment tank 1, and then the motor 403 is started, so that the rotating shaft connected to its output end through the coupling will drive the gear 401 to rotate counterclockwise. Rotate, wherein the gear 401 is meshed with the rack 40 for transmission, and the other side of the rack 40 is connected to the plugging plate 48, so the rack 40 will be inserted into the interior of the hollow frame 41 with the plugging plate 48, and then the perforation 49 opened on the surface of the plugging plate 48 will gradually enter the interior of the hollow frame 41, as the perforation 49 gradually moves downward in the hollow frame 41, the waste liquid in the treatment tank 1 will gradually enter the right half cavity of the hollow frame 41 along the perforation 49 from the top, wherein the plugging plate 48 divides the hollow frame 41 into two cavities, the left cavity is connected to the treatment tank 1, and the right cavity is isolated by the plugging plate 48, and the waste liquid in the right cavity of the hollow frame 41 will be filtered again by the No. 3 filter screen 47 until it enters the liquid outlet pipe 42 from the notch 46.

[0069] The top of the processing tank 1 is fixedly connected to a wheel support 406, the top of the wheel support 406 is rotatably connected to a fixed pulley 405, the top of the fixed pulley 405 is transmission-connected to a suspension rope 404, wherein one end of the suspension rope 404 is fixedly connected to the top of the rack 40, and the end of the suspension rope 404 away from the rack 40 is fixedly connected to a discharge piece 407, the outer side of the discharge piece 407 is slidably adapted to be equipped with a storage bin 408, and the storage bin 408 is fixedly connected to the top of the processing tank 1. The waste liquid will flow statically in the reserved basket 43, and the irradiation light 44 will illuminate the reserved basket 43. If the sensor 45 does not detect obvious colloid distribution in the reserved basket 43, the motor 403 will continue to operate. However, when the sensor 45 detects obvious colloid distribution, it will drive the motor 403 to reverse, and the blocking plate 48 will move upward to stop the outflow of the remaining waste liquid in the treatment tank 1. Then the suspension rope 404 fixedly connected to the top of the rack 40 will move to the left along the fixed pulley 405, and the discharge piece 407 fixedly connected to the other end of the suspension rope 404 will pour the coagulant in the storage bin 408 into the treatment tank 1, thereby playing a role in secondary precipitation treatment of the waste liquid that has not been completely precipitated.

[0070] At the beginning, the motor 403 rotates forward, causing the blocking plate 48 to move downward with the rack 40. At this time, the discharge piece 407 connected to the rack 40 by the suspension rope 404 will enter the storage bin 408, and the coagulant inside the storage bin 408 will be piled on the discharge piece 407. When the motor 403 does not start to rotate, the discharge piece 407 is in a state of extending from the bottom of the storage bin 408, which will seal the bottom of the storage bin 408. However, as the motor 403 reverses, the discharge piece 407 moves downward, so the coagulant piled on the discharge piece 407 will move downward with the discharge piece 407 until the coagulant falls into the remaining waste liquid.

[0071] When the present invention is used: first, the waste liquid with coagulant is put into the left end of the feed pipe 24. If the waste liquid flow in the feed pipe 24 is too large or the flow rate is too fast, the waste liquid will impact the No. 1 filter 29, and the impacted No. 1 filter 29 will move inward along the inner groove 28 opened in the feed pipe 24. The outer side of the No. 1 filter 29 is connected to the multi-fold rod 20, so the multi-fold rod 20 will move toward the direction of the treatment tank 1 and stretch the elastic pad 201, wherein the multi-fold rod 2 0 is fixedly connected to the top of the inner side thereof, and as the multi-fold rod 20 moves with the magnetic strip 202 toward the treatment tank 1, the distance between the magnetic strip 202 and the magnetic block 207 becomes closer and closer, and a repulsive force is generated between the two instead of no magnetic force, and then the magnetic block 207 affected by the repulsive force will be inserted into the interior of the feed pipe 24 with the No. 2 filter screen 204 connected thereto, and the two No. 2 filter screens 204 are spliced ​​and combined inside the feed pipe 24 to increase the filtering treatment of the waste liquid.

[0072] The waste liquid will enter the treatment tank 1 along the feed pipe 24, the elastic tube 23 and the connecting tube 21 in sequence. At this time, the waste liquid will accumulate in the treatment tank 1. As the waste liquid accumulates, the waste liquid will drive the buoyancy pad 34 to move upward, wherein the top of the buoyancy pad 34 is connected to the floating ring 32, so the floating ring 32 will move upward along the vertical rail 31, and the top of the floating ring 32 is connected to the curved block 35. At this time, the curved block 35 will squeeze the connecting tube 21 upward, and then the connecting tube 21 will move upward along the treatment tank 1, and compress and stretch the leak-proof laminated sheets 22 fixedly connected to its upper and lower sides respectively. The upward movement of the connecting tube 21 will squeeze and compress the elastic tube 23 fixedly connected to its top. At this time, the elastic tube 23 will bend and the space inside it will shrink. As the waste liquid accumulates inside the treatment tank 1, the inflow of waste liquid will be automatically reduced to avoid the subsequent excessive inflow affecting the waste liquid that has already been stationary.

[0073] When the waste liquid has been left to stand in the treatment tank 1, the protein colloid and polymer colloid precipitated by the coagulant will be at the bottom of the inner cavity of the treatment tank 1. At this time, the motor 403 is started, so that the shaft connected to its output end through the coupling will drive the gear 401 to rotate counterclockwise, wherein the gear 401 is meshed with the rack 40, and the other side of the rack 40 is connected to the plugging plate 48, so the rack 40 will be inserted into the interior of the hollow frame 41 with the plugging plate 48, and then the plugging plate 48 is opened on the surface of the plugging plate 48. The perforation 49 will gradually enter the interior of the hollow frame 41. As the perforation 49 gradually moves downward in the hollow frame 41, the waste liquid inside the treatment tank 1 will gradually enter the right half cavity of the hollow frame 41 along the perforation 49 from the top, wherein the blocking plate 48 divides the hollow frame 41 into two cavities, the left cavity is connected to the treatment tank 1, and the right cavity is isolated by the blocking plate 48, and the waste liquid in the right cavity of the hollow frame 41 will be filtered again by the No. 3 filter screen 47 until it enters the liquid outlet pipe 42 from the notch 46.

[0074] The waste liquid will flow statically in the reserved basket 43, and the irradiation light 44 will illuminate the reserved basket 43. If the sensor 45 does not detect obvious colloid distribution in the reserved basket 43, the motor 403 will continue to operate. However, when the sensor 45 detects obvious colloid distribution, it will drive the motor 403 to reverse, and the blocking plate 48 will move upward to stop the outflow of the remaining waste liquid in the treatment tank 1. Then the suspension rope 404 fixedly connected to the top of the rack 40 will move to the left along the fixed pulley 405, and the discharge piece 407 fixedly connected to the other end of the suspension rope 404 will pour the coagulant in the storage bin 408 into the treatment tank 1 to perform secondary sedimentation treatment on the waste liquid that has not been completely precipitated.

[0075] When most of the waste liquid is discharged outward, the remaining waste liquid and sediment will accumulate at the bottom of the processing tank 1. The operator manually pulls out the No. 2 plug plate 30 to expose the screen 39. At this time, the residual waste liquid will flow downward from the right half cavity of the waste pipe 36 through the screen 39, and the sediment will stay on the screen 39 and the No. 1 plug plate 38. When the residual waste liquid has flowed out, the No. 1 plug plate 38 is manually pulled out. At this time, the sediment on the No. 1 plug plate 38 and the screen 39 will move downward from the left half cavity of the waste pipe 36, so that the residual waste liquid and sediment are discharged outward through different channels.

[0076] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
