Description

Technical Field

[0001] The invention relates to the technical field of filtering and sterilizing eye protection liquid, in particular to a filtering and sterilizing device for producing eye protection liquid. Background Art

[0002] Eye drops are one of the most commonly used drug dosage forms for ophthalmic diseases. For many eye diseases, eye drops have a direct and quick therapeutic effect and can relieve visual fatigue and dry eyes. During the production process of eye drops, in order to prevent the liquid from irritating the eyes and avoid fungal infection, the original liquid needs to be filtered first, and the impurities and tiny particles in the liquid need to be filtered and screened. The liquid is then sterilized and disinfected by ultraviolet irradiation to destroy the molecular structure of DNA or RNA in the cells of the microorganism, causing growth cell death and regenerative cell death, achieving the effect of sterilization and disinfection, thereby improving the safety of patients when using eye drops.

[0003] Currently, ultraviolet light is generally used to sterilize and disinfect eye protection liquids. That is, ultraviolet lamps are placed in water or suspended on the water surface to sterilize and disinfect the liquid. However, no matter which method is used, impurities or dust will adhere to the surface of the ultraviolet lamp after long-term use, which will block the ultraviolet light and reduce the sterilization and disinfection effect of the ultraviolet lamp.

[0004] On the other hand, a patent with the search announcement number CN114573091B discloses a pure membrane MBBR device and sterilization method for electrode filtration and sterilization, which kills the detached microorganisms in the system, reduces the accumulation of detached biofilms in the system, improves operating efficiency and improves the effluent water quality. However, it is difficult for the device to continuously filter impurities and tiny particles in the liquid. In order to avoid the pain of particles when the eye solution is dripped into the eyes, it is necessary to use a PEV filter element plate to filter and screen the original liquid. However, after long-term filtration, a large amount of particles and impurities are attached to the PEV filter element plate, and the liquid permeability is reduced, resulting in a decrease in the production efficiency of the eye solution. If the PEV filter element plate is cleaned and maintained regularly, the PEV filter element plate needs to be removed from the filtration device and then cleaned. The maintenance work is cumbersome and troublesome, and the eye solution cannot be produced normally during the maintenance stage. To this end, we provide a filtration and sterilization device for the production of eye solution to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to make up for the shortcomings of the prior art and provide a filtering and sterilizing device for the production of eye protection solution, including a support seat, a cleaning cylinder is fixed above the support seat, a drain valve is installed on the outer surface of the cleaning cylinder, an ultrasonic transducer is installed on the bottom surface of the cleaning cylinder, and a sterilization mechanism is arranged on one side of the cleaning cylinder. The sterilization mechanism includes a threaded quartz glass tube, a rotating frame and an ultraviolet lamp rod. The rotating frame is sleeved on the outer surface of the ultraviolet lamp rod, and the threaded quartz glass tube is sleeved on the outside of the rotating frame.

[0006] A diverter cylinder is arranged inside the cleaning cylinder, and two support rods are fixed on the outer surface of the diverter cylinder, and the two support rods are fixed on the outer surface of the cleaning cylinder. The outer surface of the diverter cylinder is fixedly connected with a liquid inlet pipe, and a rotation mechanism is arranged inside the diverter cylinder, and the rotation mechanism includes a long tube and a blocking column, and a water flow groove is opened on the outer surface of the blocking column.

[0007] The outer surface of the diversion tube is provided with two symmetrical filtering mechanisms, and the filtering mechanisms include a fixing frame fixed on the diversion tube and a through groove opened on the diversion tube, and the through groove is adapted to the water flow channel, and two slideways are fixed on the inner wall of the fixing frame, and the two slideways are fixed on the outer surface of the diversion tube, and a cover plate is fixed on the outer surface of the fixing frame.

[0008] A bracket is fixed to the upper surface of the support seat, the bracket is fixed to the ultraviolet lamp stick, the rotating frame is rotatably connected to the bracket, a double-sided dust removal brush is fixed to the middle part of the rotating frame, a motor 1 is fixed to the outer surface of the support seat, a bevel gear 2 is fixed to the output end of the motor 1, a bevel gear 1 is fixed to the bottom end of the rotating frame, the bevel gear 1 is meshed with the bevel gear 2, and when dust exists on the surface of the threaded quartz glass tube and the ultraviolet lamp stick, the rotating frame is controlled to rotate so that the double-sided dust removal brush rotates to clean the surface of the ultraviolet lamp stick and the threaded quartz glass tube, thereby effectively avoiding the problem of impurities attached to the threaded quartz glass tube and the ultraviolet lamp stick or dust blocking the irradiation of ultraviolet rays, resulting in reduced sterilization and disinfection effects.

[0009] The bottom end of the threaded quartz glass tube is fixed on the upper surface of the support seat, and a water outlet valve is installed at the bottom end of the threaded quartz glass tube. The top of the threaded quartz glass tube is fixedly connected with a tee, and the tee is fixed to the cleaning cylinder. The outer surfaces of the two cover plates are fixedly connected with water pipes, and the two water pipes are fixedly connected with the tee. The filtered medicine flows into the threaded quartz glass tube through the tee. When the medicine is in the threaded quartz glass tube, the ultraviolet rays emitted by the ultraviolet lamp stick are used for sterilization and disinfection. By setting the threaded quartz glass tube, the time that the liquid is irradiated by the ultraviolet lamp stick is increased, and the sterilization effect is improved. The filtered and sterilized medicine is finally discharged through the water outlet valve.

[0010] The above-mentioned blocking column is fixed on the outer surface of the long tube, and the blocking column is rotatably connected to the inner wall of the diverter tube. The top end of the long tube passes through the diverter tube and is rotatably connected to the diverter tube. A fixing ring is fixed on the inner wall of the diverter tube, and the fixing ring is rotatably connected to the long tube. A second motor is fixed on the outer surface of the diverter tube. The output end of the second motor is transmission-connected to the long tube through a belt and a pulley. The second motor is controlled to drive the long tube to rotate, so that the blocking column on the long tube rotates 180 degrees. The blocking column will block the through groove on one side, and the through groove on the other side will be connected to the inside of the diverter tube through the water flow groove, thereby controlling the rotation of the blocking column and controlling the flow direction of the liquid in the diverter tube.

[0011] Furthermore, a motor three is fixed to the outer surface of the diverter cylinder, a threaded rod is fixed to the output end of the motor three, a threaded block is threadedly connected to the outer surface of the threaded rod, and a long sliding rod is rotatably connected to the bottom surface of the threaded block.

[0012] The long sliding rod passes through the long tube and is slidably connected to the long tube. Two sliding bars are fixed on the inner wall of the long tube, and the two sliding bars are slidably connected to the long sliding rod. Support arms are fixed to the bottom ends of the long sliding rod and the long tube, and arc-shaped sliding rails are fixed to the top ends of the two support arms. The two arc-shaped sliding rails are symmetrical to each other, and the arc-shaped sliding rails on the long tube are located on one side of the water flow trough, and the arc-shaped sliding rails on the bottom of the long sliding rod are located on the side away from the water flow trough. The control motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the long sliding rod to move downward through the threaded block. The arc-shaped sliding rail on the long sliding rod will pull one side of the PEV filter element plate to move downward, and the through groove at the PEV filter element plate on this side is in a state of being blocked by the blocking column.

[0013] The above-mentioned filtering mechanism also includes a PEV filter element plate, and the two slideways are both sealingly and slidingly connected to the PEV filter element plate. A semi-annular slider is fixed to the bottom surface of the PEV filter element plate, and the arc-shaped slide rail is slidably connected to the semi-annular slider. A sealing groove is opened on the upper surface of the semi-annular slider, and a sealing strip matched with the sealing groove is fixed to the bottom surface of the cover plate. When the PEV filter element plate is located between the cover plate and the fixing frame, the fixing frame, the cover plate and the semi-annular slider form a sealed cavity, and the sealing of the bottom of the cavity is increased by the sealing groove and the sealing strip. When the liquid in the diversion cylinder is discharged through the through groove, impurities and particles are first filtered by the PEV filter element plate, and then flow through the cavity formed by the fixing frame, the cover plate and the semi-annular slider, and finally discharged to the outside through the water pipe.

[0014] Compared with the prior art, the filtration and sterilization device for eye protection solution production has the following beneficial effects:

[0015] 1. The present invention is provided with a rotation mechanism and a filtering mechanism. External liquid flows through the water flow trough and the through groove on one side, and passes through the PEV filter element plate on one side to filter impurities and particles. When the filtering effect of the PEV filter element plate on this side weakens, the blocking column is controlled to rotate to rotate the water flow trough to the PEV filter element plate on the other side, so that the liquid flows through the clean PEV filter element plate on the other side for filtration, and the PEV filter element plate covered with impurities and particles will be moved downward to the bottom of the cleaning cylinder, and the PEV filter element plate will be ultrasonically cleaned by an ultrasonic transducer. The cleaned PEV filter element plate will be reset upward to wait for the next rotation. By rotating the two PEV filter element plates and cleaning them in an offset manner, the PEV filter element plate does not need to stop the filtering operation during the maintenance and cleaning process. The device can continuously filter impurities and tiny particles in the liquid, which is convenient and fast.

[0016] 2. The present invention is provided with a sterilization mechanism, and the filtered liquid will flow through the threaded quartz glass tube through the three-way pipe. The setting of the threaded quartz glass tube increases the time that the liquid is irradiated by the ultraviolet lamp rod, thereby improving the sterilization effect. When dust exists on the surface of the threaded quartz glass tube and the ultraviolet lamp rod, the rotating frame is controlled to rotate, so that the double-sided dust removal brush rotates to clean the surface of the ultraviolet lamp rod and the threaded quartz glass tube, thereby effectively avoiding the problem that impurities attached to the threaded quartz glass tube and the ultraviolet lamp rod or dust blocking the irradiation of ultraviolet rays leads to reduced sterilization and disinfection effects.

The rotating frame 405 is sleeved on the outer surface of the ultraviolet lamp stick 410, and the threaded quartz glass tube 401 is sleeved on the outside of the rotating frame 405. A bracket 404 is fixed to the upper surface of the support seat 1, and the bracket 404 is fixed to the ultraviolet lamp stick 410. The rotating frame 405 is rotatably connected to the bracket 404.

By setting the threaded quartz glass tube 401, the time the liquid is irradiated by the ultraviolet lamp stick 410 is increased, and the sterilization effect is improved. The filtered and sterilized liquid medicine is finally discharged through the water outlet valve 403.

[0047] Working principle: When filtering and sterilizing the medicine liquid, the medicine liquid will enter the diversion tube 3 through the liquid inlet pipe 7, and the medicine liquid in the diversion tube 3 will pass through the water flow groove 803 and the side groove 901, and pass through the side PEV filter element plate 904 to filter impurities and particles, and then the medicine liquid will flow into the water pipe 909, and then flow into the threaded quartz glass tube 401 through the three-way pipe 402. When the medicine liquid is in the threaded quartz glass tube 401, it will be sterilized and disinfected by the ultraviolet light emitted by the ultraviolet lamp rod 410, and the filtered and sterilized medicine liquid will be finally discharged through the water outlet valve 403.

[0048] When the filtering effect of the PEV filter element plate 904 on one side is weakened, the control motor 2 805 drives the long tube 801 to rotate, so that the blocking column 802 rotates 180 degrees, and the water flow channel 803 on the blocking column 802 rotates to the PEV filter element plate 904 on the other side, so that the liquid flows through the clean PEV filter element plate 904 on the other side for filtration, and then the control motor 3 807 drives the threaded rod 808 to rotate. The rotation of the threaded rod 808 will drive the long slide rod 810 to move downward through the threaded block 809, and the arc slide rail 812 at the bottom of the long slide rod 810 will pull the semi-annular slider 90 downward. 5, the PEV filter element plate 904 covered with impurities and particles is moved downward to the bottom of the cleaning cylinder 2, and the PEV filter element plate 904 is ultrasonically cleaned by the ultrasonic transducer 6, and the cleaned PEV filter element plate 904 is reset upward to wait for the next rotation, and the sewage in the cleaning cylinder 2 is discharged through the drain valve 10. The device uses two PEV filter element plates 904 in rotation and washes them in an offset manner, so that the PEV filter element plate 904 does not need to suspend the filtering operation during the maintenance and cleaning process. The device can continuously filter impurities and tiny particles in the liquid, which is convenient and fast.

[0049] The filtered liquid will flow through the threaded quartz glass tube 401 through the three-way pipe 402. The setting of the threaded quartz glass tube 401 increases the time for the liquid to be irradiated by the ultraviolet lamp rod 410, thereby improving the sterilization effect. When dust exists on the surface of the threaded quartz glass tube 401 and the ultraviolet lamp rod 410, the rotating frame 405 is controlled to rotate, so that the double-sided dust removal brush 406 rotates to clean the surface of the ultraviolet lamp rod 410 and the threaded quartz glass tube 401, thereby effectively avoiding the problem of impurities attached to the threaded quartz glass tube 401 and the ultraviolet lamp rod 410 or dust blocking the irradiation of ultraviolet rays, resulting in reduced sterilization and disinfection effects.
