[0025] A wastewater treatment process for eye drop preparation comprises the following steps:

[0026] Step one: the waste liquid into which a coagulant is poured is introduced from the left end of the inlet pipe, and then passes through the first filter screen, at this time, the first filter screen performs preliminary filtering treatment on the impurities in the waste liquid, and finally enters the treatment tank;

[0027] Step two: as the waste liquid accumulates in the treatment tank, the waste liquid drives the buoyant pad and the floating ring to move upward, the top of the floating ring is connected with the curved block, at this time, the curved block extrudes the connecting pipe upward, and then the connecting pipe moves upward along the treatment tank and extrudes and compresses the elastic pipe fixedly connected to the top of the connecting pipe, at this time, the elastic pipe is bent and the space in the elastic pipe is reduced, to automatically reduce the inflow of the waste liquid and avoid the influence of the subsequent inflow on the waste liquid which has been statically settled;

[0029] Compared with the prior art, the beneficial effects of the present application are:

[0030] 1. By splicing and combining two No. 2 filter screens 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 screen due to excessive wastewater flow or excessive 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 screen.

[0031] 2. As the multi-fold rod continues to move toward the treatment tank, the triangular block fixed to its other end will pass through the frame rod and squeeze the flow limiting plate. The contact surface between the two is an inclined surface, 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 preventing excessive flow from causing 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 will become narrower, thereby automatically reducing the inflow of waste liquid as the waste liquid accumulates inside the treatment tank, so as to avoid the subsequent use of the initial large inflow and affecting the waste liquid after it has been settled.

[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 inside the storage bin into the treatment tank, thereby performing secondary sedimentation treatment on 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.

The top of the floating ring 32 is connected with the curved block 35, at this time the curved block 35 will extrude the connecting pipe 21 upward, then the connecting pipe 21 will move upward along the treatment tank 1 and compress and stretch the leak-proof laminations 22 fixedly connected to the upper and lower sides thereof, wherein the leak-proof laminations 22 are elastic and play a role of preventing the waste liquid in the treatment tank 1 from overflowing outward, the upward movement of the connecting pipe 21 will extrude and compress the elastic pipe 23 fixedly connected to the top of the connecting pipe 21, at this time the elastic pipe 23 will be bent and the space in the elastic pipe 23 will be reduced, and the reduction is that the space in the elastic pipe 23 is narrowed, and at the same time the space in the elastic pipe 23 is gradually narrowed with the upward movement of the connecting pipe 21, thereby playing a role of automatically reducing the inflow amount of the waste liquid with the accumulation of the waste liquid in the treatment tank 1, so as to avoid that the subsequent still uses a larger inflow amount at the beginning and affects the waste liquid after the former has been statically settled.

[0055] The upper and lower sides of the inner cavity of the feeding pipe 24 are provided with inner grooves 28, the inner grooves 28 are slidably fitted with a first filter screen 29, the outer side of the first filter screen 29 is fixedly connected with a multi-fold rod 20, the outer side of the multi-fold rod 20 is fixedly connected with an elastic pad 201, and the elastic pad 201 is fixedly connected with the top of the feeding pipe 24; the waste liquid into which the coagulant is put in from the left end of the feeding pipe 24, wherein the coagulant is not put into the inner cavity of the feeding pipe 24 after being mixed and stirred in the waste liquid for a long time, but is put into the inner cavity of the feeding pipe 24 when the waste liquid is ready to enter the inner cavity of the feeding pipe 24, if the flow amount or flow speed of the waste liquid in the feeding pipe 24 is too large or too fast, the waste liquid will impact the first filter screen 29, and the first filter screen 29 impacted will move inward along the inner grooves 28 provided in the inner cavity of the feeding pipe 24, wherein the outer side of the first filter screen 29 is connected with the multi-fold rod 20, so the multi-fold rod 20 will move towards the treatment tank 1 and stretch the elastic pad 201, wherein the elastic pad 201 is elastic and plays a role of resetting the multi-fold rod 20 and the first filter screen 29, and also plays a role of preventing the multi-fold rod 20 from opening the upper and lower ends of the feeding pipe 24 during the movement and causing the waste liquid to overflow outward.

[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;

In addition, the flow rate being too fast will also have a greater impact on the subsequent waste liquid standing.

[0058] The upper and lower sides of the inlet pipe 24 are both inserted with a No. 2 filter screen 204, the top of the No. 2 filter screen 204 is fixedly connected with a magnetic block 207, the two sides of the No. 2 filter screen 204 are both symmetrically connected with an extension piece 205, the bottom of the extension piece 205 is fixedly connected with an elastic telescopic rod 206, and the end of the elastic telescopic rod 206 away from the extension piece 205 is fixedly connected with the inlet pipe 24. The top of the inner side of the multi-fold rod 20 is fixedly connected with a magnetic strip 202, and as the multi-fold rod 20 moves towards the direction of the treatment tank 1 with the magnetic strip 202, the distance between the magnetic strip 202 and the magnetic block 207 will become closer and closer, and the magnetic force between the two will change from no magnetic force to repulsion, and then the magnetic block 207 affected by the repulsion will insert the No. 2 filter screen 204 connected therewith into the inside of the inlet pipe 24, and the two No. 2 filter screens 204 are spliced and combined inside the inlet pipe 24, thereby playing a role of increasing the filtering treatment of impurities in the waste water inside the inlet pipe 24, and also playing a role of avoiding that the No. 1 filter screen 29 is not completely filtered due to the waste water flow being too large or the flow rate being too fast, and also playing a role of adjusting the extension and retraction of the No. 2 filter screen 204 by using the size of the waste liquid flow and the speed of the flow rate. The two sides of the No. 2 filter screen 204 are also symmetrically connected with the extension piece 205, and the bottom of the extension piece 205 is connected with the elastic telescopic rod 206, and the elastic telescopic rod 206 plays a role of resetting the No. 2 filter screen 204.

[0059] As shown in Figure 7 , Figure 8 and Figure 9 , the flow distribution mechanism 3 comprises a vertical rail 31 fixedly installed inside the treatment tank 1, and the inside of the vertical rail 31 is slidably fitted with a floating ring 32.

[0060] A buoyancy pad 34 is arranged for increasing the buoyancy of the floating ring 32 and is fixedly connected to the bottom of the floating ring 32.

[0061] A counterweight 33 is arranged for balancing the force of the floating ring 32 and is fixedly connected to the top of the floating ring 32.

[0066] A second plug plate 30 is used for closing and processing the screen 39, and is inserted into the outer side of the waste pipe 36 and extends to the inside thereof. When most of the waste liquid is discharged outwardly, the residual waste liquid and the precipitate are accumulated at the bottom of the processing tank 1. By manually pulling out the second plug plate 30 outwardly, the screen 39 is exposed, and at this time, the residual waste liquid flows downwardly from the right half cavity of the waste pipe 36 through the screen 39, and the precipitate is retained on the screen 39 and the first plug plate 38. When the residual waste liquid is completely discharged, the first plug plate 38 is manually pulled out outwardly, and at this time, the precipitate on the first plug plate 38 and the screen 39 is moved downwardly from the left half cavity of the waste pipe 36, thereby achieving the effect of discharging and processing the residual waste liquid and the precipitate through different channels.

[0067] As shown in Figure 10 , Figure 11 , Figure 12 and Figure 13 , the filling mechanism 4 comprises a hollow frame 41 fixedly connected to the outer side of the processing tank 1, an opening 46 is formed at the side of the hollow frame 41 away from the processing tank 1, and an outlet pipe 42 is fixedly connected thereto. The outer side of the outlet pipe 42 is fixedly connected with a reserved basket 43, the outer side of the reserved basket 43 is fixedly installed with an irradiation light 44, and the top of the reserved basket 43 is fixedly installed with a sensor 45;

[0068] The interior of the hollow frame 41 is fixedly connected to a No. 3 filter screen 47, and the upper and lower ends of the hollow frame 41 are plugged with blocking plates 48. The surface of the blocking plate 48 is provided with a perforation 49. The outer side of the blocking plate 48 is fixedly connected to a rack 40, and the outer side of the rack 40 is meshed with a gear 401. The gear 401 is rotatably connected to the bracket 402 through a rotating shaft, wherein the rotating shaft is connected to a motor 403 through a coupling. The motor 403 is fixedly connected to the outer side of the bracket 402, and the bracket 402 is fixedly connected to the outer side 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 at this time, 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. Rotation, wherein the gear 401 is meshed with the rack 40 for transmission, and the other side of the rack 40 is connected to the blocking plate 48, so the rack 40 will be inserted into the interior of the hollow frame 41 with the blocking plate 48, and then the perforation 49 opened on the surface of the blocking 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 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 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, and the outer side of the discharge piece 407 is slidingly adapted to be fitted 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. At this time, the blocking plate 48 will move upward and 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 the role of secondary precipitation treatment of the waste liquid that has not been completely precipitated.

[0070] The motor 403 rotates in the positive direction at first, so that the blocking plate 48 moves downward with the rack 40, and at this time the discharging element 407 connected with the rack 40 through the lifting rope 404 enters into the storage bin 408, and the coagulant in the storage bin 408 piles on the discharging element 407, and when the motor 403 does not rotate, the discharging element 407 is in a state of extending from the bottom of the storage bin 408, which seals the bottom of the storage bin 408, but with the reverse rotation of the motor 403, the discharging element 407 moves downward, so that the coagulant piled on the discharging element 407 moves downward together with the discharging element 407, until the coagulant falls into the remaining waste liquid.

[0071] In use, first, the waste liquid with coagulant is poured from the left end of the feeding pipe 24, and when the flow of the waste liquid in the feeding pipe 24 is too large or the flow rate is too fast, the waste liquid will impact the first filter screen 29, and the first filter screen 29 impacted will move inward along the inner groove 28 in the feeding pipe 24, and the outer side of the first filter screen 29 is connected with the multi-fold lever 20, so that the multi-fold lever 20 moves toward the treatment tank 1 and stretches the elastic pad 201, and the top of the inner side of the multi-fold lever 20 is fixedly connected with the magnetic strip 202, and with the movement of the multi-fold lever 20 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 the magnetic force between them changes from no magnetic force to repulsion, and then the magnetic block 207 affected by the repulsion inserts into the feeding pipe 24 with the second filter screen 204 connected therewith, and the two second filter screens 204 are spliced and combined in the feeding pipe 24 to increase the filtering treatment of the waste liquid.

[0072] The waste liquid enters into the treatment tank 1 along the feeding pipe 24, the elastic pipe 23 and the connecting pipe 21 in sequence, and at this time the waste liquid accumulates in the treatment tank 1, and with the accumulation of the waste liquid, the waste liquid drives the buoyant pad 34 to move upward, and the top of the buoyant pad 34 is connected with the floating ring 32, so that the floating ring 32 moves upward along the vertical rail 31, and the top of the floating ring 32 is connected with the curved block 35, and at this time the curved block 35 extrudes the connecting pipe 21 upward, and then the connecting pipe 21 moves upward along the treatment tank 1 and compresses and stretches the leak-proof laminations 22 fixedly connected on the upper and lower sides thereof, and the upward movement of the connecting pipe 21 extrudes and compresses the elastic pipe 23 fixedly connected on the top thereof, and at this time the elastic pipe 23 bends and the space in the elastic pipe 23 reduces, and with the accumulation of the waste liquid in the treatment tank 1, the inflow amount of the waste liquid is automatically reduced, so as to avoid that the subsequent inflow amount is too large to affect the waste liquid which has been statically settled.

[0073] When the waste liquid is settled in the processing tank 1, the protein colloid and polymer colloid precipitated by the coagulant are at the bottom of the inner cavity of the processing tank 1, at this time, the motor 403 is started, so that the rotating shaft connected with the output end through the shaft coupling rotates counterclockwise with the gear 401, the gear 401 is in meshing transmission with the rack 40, and the other side of the rack 40 is connected with the baffle plate 48, so that the rack 40 inserts the baffle plate 48 into the hollow frame 41, and then the perforations 49 on the surface of the baffle plate 48 gradually enter the hollow frame 41, as the perforations 49 gradually move downward in the hollow frame 41, the waste liquid in the processing tank 1 gradually enters the right half cavity of the hollow frame 41 from the top along the perforations 49, wherein the baffle plate 48 divides the hollow frame 41 into two cavities, the left cavity is communicated with the processing tank 1, and the right cavity is isolated by the baffle plate 48, and the waste liquid in the right cavity of the hollow frame 41 is filtered again by the third filter screen 47, and then enters the liquid outlet pipe 42 from the gap 46.

[0074] The waste liquid flows in the reserved basket 43, at this time, the illumination light 44 illuminates the reserved basket 43, if the sensor 45 does not detect obvious colloid distribution in the reserved basket 43, the motor 403 continues to operate, but when the sensor 45 detects obvious colloid distribution, the motor 403 is reversed, at this time, the baffle plate 48 moves upward and stops the flow of the remaining waste liquid in the processing tank 1, then the hanging rope 404 fixedly connected to the top end of the rack 40 moves left along the fixed pulley 405, and the discharging part 407 fixedly connected to the other end of the hanging rope 404 pours the coagulant in the storage bin 408 into the processing tank 1, to perform secondary precipitation treatment on the waste liquid which has not been precipitated.

[0075] When most of the waste liquid is discharged outward, the residual waste liquid and the precipitate accumulate at the bottom of the processing tank 1, the second plug plate 30 is manually pulled out by the operator, so that the screen 39 is exposed, at this time, the residual waste liquid flows downward from the right half cavity of the waste pipe 36 through the screen 39, and the precipitate stays 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 precipitate on the first plug plate 38 and the screen 39 respectively moves downward from the left half cavity of the waste pipe 36, to discharge the residual waste liquid and the precipitate outward through different channels.

[0076] The above embodiment is only a preferred embodiment of the present application, and cannot be used to limit the protection scope of the present application, and those skilled in the art can make various modifications without creative labor, which are all within the protection scope of the present application.
