Abstract
The utility model discloses a filtering and filling device of a contact lens preservation solution. According to the technical scheme, a first filter and a second filter are arranged on a preservation solution outflow pipeline, the preservation solution flows out to enter a solution storage box, the solution storage box is arranged on a weighing sensor, and the weighing sensor is connected with a control valve and a power pump. The filtering and filling device disclosed by the utility model has the beneficial effects that dual films are used for filtering to ensure the least impurity; the opening/closing of an outlet is controlled by the weight change of the solution storage box, thereby being convenient and reliable; a storage cavity is arranged, so that the solution in the pipeline is buffered when the outlet is closed.
Description
Technical field
The utility model belongs to medical equipment production equipment field, relates to a kind of contact lenses and preserves liquid filtration filling apparatus.
Background technology
Contact lenses are in when packaging, and the preservation liquid of use, after the packaging of being everlasting during in quality inspection, finding has a lot of foreign material in water, and tiny feeler thing swims in physiological saline, causes like this packaging water quality not reach standard, the high production cost that causes of rework rate increases, waste resource.The container of preserving liquid due to storage is little, easily spill-over, bad control.
Utility model content
The utility model object is that the tiny foreign material of solution contact lenses preservation liquid are many, causes the problem of disqualification rate height and bad control inputs amount, provides a kind of contact lenses to preserve liquid and filters filling apparatus.
The technical solution of the utility model is: a kind of contact lenses are preserved liquid and filtered filling apparatus, flow out on pipeline the first filter, the second filter are set at preservation liquid, preserve liquid outflow and enter liquid storage box, liquid storage box is arranged on weight sensor, and weight sensor connects control valve and kinetic pump.
Described first, second filter is film changeable syringe-driven filter, is 0.6 micron of micropore permeation film in filter.
Pipeline between described the first filter and the second filter is provided with storage chamber.
The beneficial effects of the utility model are: 1) duplex film filters, and makes impurity minimum; 2) by liquid storage box changes in weight control outlet break-make, convenient and reliable; 3) be provided with storage chamber, when port closing, make liquid in pipeline be cushioned.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail
A kind of contact lenses are preserved liquid and are filtered filling apparatus, flow out on pipeline the first filter 2, the second filter 4 are set at preservation liquid, pipeline between the first filter and the second filter is provided with storage chamber 3, preserve liquid outflow and enter liquid storage box 6, liquid storage box 6 is arranged on weight sensor 7, weight sensor 7 connects control valve 5 and kinetic pump 1, and first, second filter is film changeable syringe-driven filter, is 0.6 micron of micropore permeation film in filter.
When use, responded to the changes in weight of certain limit by weight sensor, so the opening and closing of sending signal controlling control valve and kinetic pump, in the time that the two is all opened, to liquid storage box topping up, liquid storage box reaches after constant weight, and the two is closed, and stops topping up; Carry out double filtration by the first filter, the second filter, for avoiding two filter liquid Negotiation speeds slow, add kinetic pump, the storage chamber that liquid in pipe is cushioned is set between two filters.
