Description
Technical Field
The utility model relates to an aseptic packaging equipment technical field especially relates to a liquid medicament's quantitative feeding machine.
Background
In the technical field of aseptic packaging equipment, in particular aseptic filling equipment, sterilization of packaging containers is not necessary. Packaging or filling under aseptic conditions requires that the packaging material is first sterilized. There are various methods for sterilizing packaging materials, such as irradiation method, UV irradiation method, electron beam method, etc., but currently, the most common and most economical sterilization method in the market is sterilization by using chemical agents, such as peracetic acid (PAA) and hydrogen peroxide (H2O2), which are currently commonly used chemical bactericides.
The method for sterilizing by adopting the chemical liquid medicament needs to control the concentration and the usage amount of the bactericide, not only avoids the problem that the sterilization rate is not up to standard due to insufficient usage amount of the bactericide, but also avoids the problems that the concentration and the usage amount are too high, waste is caused, and the subsequent removal of the bactericide residue is difficult, and the effective sterilization and the economic sterilization of equipment are required.
For continuously operating equipment, a flow meter or a dosing pump is generally adopted to control and obtain stable bactericide concentration and feeding time, and equipment operating at a fixed beat, such as a linear multi-row sterile filling machine, needs to accurately control the sterilization dosage to each sterilization object, specifically, each filling bottle.

Therefore, there is a need in the art for a convenient instrument for quantitative sterilization that solves the above problems.

In the prior art, a dosing system for liquid medicament is generally fed by a dosing pump or a flow meter and a switch valve, but the feeding aspect is technically difficult to realize, on one hand, because the medicament required by each filling bottle is metered very little during sterilization feeding, the action frequency of equipment which runs at high speed is very high, and the feeding time is very short, so that a sterilization system which is fed by the general dosing pump or the flow meter and the valve is difficult to obtain relatively accurate feeding metering.
The quantitative feeder of the liquid medicament in the technical scheme comprises a driving device 1, a quantitative cup 2, a material storage device 3 and a controller (not shown in the figure), wherein the driving device 1 is electrically connected with the controller, the quantitative cup 2 is driven by the driving device 1, the quantitative cup 2 is arranged in the material storage device 3 in a vertically movable manner, and the quantitative cup 2 is used for taking materials in the material storage device 3; the storage device 3 is provided with a feeding hole 4 and a suction hole 5, the feeding hole 4 is used for the liquid medicament to enter the storage device 3, and specifically, the feeding hole 4 can be externally connected with a storage bin of the liquid medicament; the suction port 5 is used for sucking the liquid medicament in the quantitative cup 2, specifically, the suction port 5 may be externally connected with a suction device, and the suction device may be an instrument having suction capability such as a suction pump or a venturi tube.
The working principle of the quantitative feeder is as follows:
the medicament enters the material storage device 3 through the material inlet 4, and a certain liquid level height is formed in the material storage device 3; (2) the quantitative cup 2 moves towards the bottom of the storage device 3 under the driving of the driving device 1, so that the cup mouth horizontal plane of the quantitative cup 2 is lower than the liquid level height in the storage device 3, and the medicine enters from the cup mouth horizontal plane of the quantitative cup 2 and fills the cup body of the quantitative cup 2; (3) after the cup body of the quantitative cup 2 is filled with the medicament, the quantitative cup 2 moves towards the material sucking port 5 of the material storage device 3 under the driving of the driving device 1, so that the horizontal plane of the cup mouth of the quantitative cup 2 is higher than the liquid level in the material storage device 3; (4) the medicine in the quantitative cup 2 is sucked to the outside of the storing device 1 through the sucking port 5.
Because the dosage of the liquid medicament at each beat needs to be controlled when the liquid medicament is used, in the technical scheme, a quantitative cup 2 with rated capacity is replaced by a quantitative container from a commonly adopted quantitative pump or a flowmeter, so that the quantitative requirement when the liquid medicament is used is ensured to be met; specifically, according to the requirement of the concentration of the original liquid of the medicament and the concentration of the used medicament, different quantitative cups 2 are provided with different rated capacities, and the quantitative requirements on different requirements can be realized when the liquid medicament is used by replacing the quantitative cups 2 with different rated capacities. And because when using liquid medicament to sterilize, the medicament that each filling bottle needs measures very little, and the apparatus that runs at a high speed with the beat often moves the frequency very high, it is very short when each beat, the sterilization system that general measuring pump and valve supply, it is difficult to obtain relatively accurate feed measurement, but use the quantitative cup 2 with rated capacity in this technical scheme, only need to guarantee when the quantitative cup 2 is located the lowest position of the range of movement, the liquid level height in the storing device 3 is higher than the horizontal plane of the rim of a cup of the quantitative cup 2, can guarantee the medicament is full of the quantitative cup 2, and the medicament capacity of the quantitative cup 2 is the medicament dosage that the sterilization needs at this moment, simple in construction is rational, the implement method is simple and reliable, can guarantee relatively accurate feed measurement.
