Abstract
The utility model relates to a large-volume injection filtration system which belongs to the technical field of medicine production equipment. The large-volume injection filtration system comprises a diluting tank, a material conveying pump, a first control valve, first-grade filters, second-grade filters, third-grade filters and a second control valve which are sequentially connected, and a controller, wherein at least two paths of first-grade filters are arranged in parallel; pressure sensors are fixedly arranged on the first-grade filters; the first control valve and the pressure sensors are all connected with the controller through data lines. The large-volume injection filtration system is reasonable in design, i.e., the service lives of the second-grade filters and the third-grade filters can be greatly prolonged by monitoring the first-grade filters in real time, so that the maintenance cost of the filtration system is lowered; meanwhile, the continuous running of the filtration system is ensured, so that the production efficiency is not influenced.
Description
Technical field
The utility model relates to a kind of high-capacity injection filtration system, belongs to medical production equipment technical field.
Background technology
Along with the development of current medical technology, the checking for material system in new edition GMP is also more and more stricter, this cleaning comprising equipment, pipeline portions and sterilizing checking, and require also more and more stricter for the filter of material-transporting system.In existing high-capacity injection material-transporting system, to the filter between bottle placer, general to adopt 1 filtering accuracy be 0.45 μ m and 2 filter series connection that filtering accuracy is 0.22 μ m to dilute preparing tank, and material is delivered to bottle placer by feed liquid after by this filter mechanism.Current filter mechanism has following deficiency: filter mechanism need to be processed a large amount of materials, first order filter easily stops up or damages, directly cause follow-up two, tertiary filter load to increase the weight of, filter efficiency reduces, when serious, cause two, tertiary filter damages, filter effect is difficult to ensure, therefore, need to develops a kind of novel high-capacity injection filtration system.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of high-capacity injection filtration system is provided.
The utility model solves the technical scheme that its technical problem adopts:
High-capacity injection filtration system, comprise the dilute preparing tank, feeding engine, the first control valve, grade one filter, secondary filter, tertiary filter and the second control valve that connect successively, also comprise controller, the at least parallel two-way that arranges of described grade one filter, on described grade one filter, be fixed with pressure sensor, described the first control valve is all connected with controller by data wire with pressure sensor.
As described in background, because treating capacity is large, grade one filter easily stops up or damages, directly cause follow-up two, tertiary filter load increases the weight of, filter efficiency reduces, when serious, cause two, tertiary filter damages, filter effect is difficult to ensure, the utility model considers the filtration condition of grade one filter to monitor in real time for this reason, grade one filter has designed two-way for this reason, when use, first open a road, by pressure sensor, the internal pressure of grade one filter is detected, in the time that grade one filter stops up, internal pressure can sharply rise, in the time that grade one filter damages, internal pressure can sharply reduce, pressure sensor reaches pressure change signal in controller, controller can with predefined pressure on, lower limit contrasts, in the time exceeding this scope, the first control valve that controller can be controlled on this road is closed, open another road simultaneously, by the monitoring to grade one filter, can greatly extend two, the service life of tertiary filter, can ensure that filtration system continues to run without interruption, do not affect production efficiency.
As preferably, described controller adopts PLC controller, and described PLC controller is also connected with acoustic-optic alarm.Can remind direct labor by acoustic-optic alarm, filtration system needs to safeguard, cleaning, and the utility model automaticity is high.
As preferably, the filtering accuracy of described grade one filter is 0.45 μ m, the filtering accuracy≤0.2 μ m of secondary filter, the filtering accuracy≤0.2 μ m of tertiary filter.
The beneficial effects of the utility model are: the utility model is reasonable in design, by the real-time monitoring to grade one filter, can greatly extend two, the service life of tertiary filter, reduce the maintenance cost of filtration system, can ensure that filtration system continues to run without interruption, do not affect production efficiency simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, dilute preparing tank, 2, feed pump, 3, the first control valve, 4, grade one filter, 41, pressure sensor, 5, secondary filter, 6, tertiary filter, 7, the second control valve, 8, controller.
Detailed description of the invention
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
High-capacity injection filtration system as shown in Figure 1, comprise the dilute preparing tank 1 connecting successively, feeding engine 2, the first control valve 3, grade one filter 4, secondary filter 5, tertiary filter 6 and the second control valve 7, this system also comprises controller 8, the parallel two-way that arranges of described grade one filter 4, on described grade one filter 4, pressure sensor 41 is installed, described the first control valve 3 is all connected with controller 8 by data wire with pressure sensor 41, controller 8 described in the present embodiment adopts PLC controller, described PLC controller is also connected with acoustic-optic alarm, the filtering accuracy of described grade one filter 4 is 0.45 μ m, filtering accuracy≤0.2 μ the m of secondary filter 5, filtering accuracy≤0.2 μ the m of tertiary filter 6.
When use, first open a road, by pressure sensor 41, the internal pressure of grade one filter 4 is detected, in the time that grade one filter 4 stops up, internal pressure can sharply rise, in the time that grade one filter 4 damages, internal pressure can sharply reduce, pressure sensor 41 reaches pressure change signal in controller 8, controller 8 can contrast with predefined pressure upper limit value and lower limit value, in the time exceeding this scope, the first control valve 3 that controller 8 can be controlled on this road is closed, and opens another road simultaneously, ensure that filtration system continues to run without interruption, do not affect production efficiency.
Above-described embodiment is preferably scheme of one of the present utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim records.
