Description
Technical field
The utility model relates to a kind of plastic bottle infusion filling device, belongs to field of pharmaceutical machinery.
Background technology
Existing rotary bottle placer is because the requirement of speed of production adopts a plurality of fill head to carry out can mostly, according to fluid mechanics principle, the switch of can mouth directly influences adjacent filling pressure on every side, and therefore existing can principle can only could guarantee filling accuracy under the situation of moulding the successive supply of bottle.And in plastic bottle infusion solutions production process, because not matching of headend equipment often need be produced under discontinuous situation for bottle, under disconnected bottle situation, the filling accuracy of filling apparatus is difficult to guarantee.In addition, in the existing filling apparatus, between dilute preparing tank and the bottle placer elevated tank is set, the balance that keep-ups pressure of the mode by the elevated tank overflow, but elevated tank exists following defective: adopts the mode of opening wide on the structure, is communicated with, can not realize online sterilization with atmosphere; Be subjected to limitation in height, filling pressure is low, and (0.02～0.03Mpa) filling speed is slow, can not satisfy the requirement of quick can; When can finishes, remain soup pressure transient in jar and cause and to realize auto-filling, reduced filling accuracy; Evacuable not during jar inner liquid medicine on-line cleaning causes very big waste during bottle placer drug-feeding tube on-line cleaning.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of simple in structure, easy to use, can satisfy low speed can and high-speed canning requirement simultaneously and can guarantee continuous can simultaneously and plastic bottle infusion filling device that the filling accuracy of disconnected bottle can requires.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of plastic bottle infusion filling device, be provided with pressure balancing tank between dilute preparing tank and the bottle placer, soup in the dilute preparing tank enters in the pressure balancing tank through variable frequency pump and by the physic liquor intake tube road, the physic liquor intake tube road is provided with diaphragm valve, the top of pressure balancing tank is provided with pressure-detecting device, liquid level detection device, numerical indication adjusting apparatus, connects the admission line and the pneumatic PID control apparatus of clean compressed gas, and the drug liquid pipeline of equilibrium of pressure pot bottom inserts bottle placer.
Fully enclosed buffering cup is set before the can mouth of bottle placer, and gas circuit is installed in the upper end of buffering cup.When filling pressure is too big in the pouring process, the soup flow velocity is too fast to be overflowed in bottle easily, therefore fully enclosed buffering cup is set before the can mouth can prevents that this phenomenon from producing, but fully enclosed buffering cup when stopping can because of there not being pressure, liquid in the buffering cup is no longer mobile, therefore in the upper end of buffering cup gas circuit has been installed, has fed clean compressed air or nitrogen, can guarantee that like this liquid that enters the buffering cup all flows to end through filtering.
The production craft step of plastic bottle infusion filling is as follows: soup is through dilute preparing tank, and---variable frequency pump---------the buffering cup is put in storage pressure balancing tank in can---loam cake heat-sealing mouth---by finished product packing.
Adopt variable frequency pump to carry soup, can well suppress the fluctuation of fluid pressure in the physic liquor intake tube road, the equilibrium of pressure upper end is provided with pressure-detecting device, variable frequency pump carries out variable frequency control according to the fluctuation of pressure, thereby guarantees to enter the interior physic liquor intake tube road pressure of pressure balancing tank in a normal range.
Adopt pressure balancing tank to replace elevated tank, its principle of work is: clean compressed gas is in admission line enters closed pressure balancing tank, when the drug liquid pipeline does not arrhea when soup, liquid level in the pressure balancing tank is along with decline, pressure in jar reduces, pneumatic PID control apparatus is regulated pressure by the intake and exhaust of controlling pneumatic PID control apparatus under the instruction of numerical indication adjusting apparatus at this moment, and the pressure in the pressure balancing tank is kept in balance; Along with the decline of liquid level, liquid level detection device sends instruction, the opening of diaphragm valve on the control physic liquor intake tube road, thus replenish soup.When soup adds to setting value, SELF CL diaphragm valve, soup no longer enter pressure balancing tank.Owing between dilute preparing tank and bottle placer, set up pressure balancing tank, make the filling pressure of plastic bottle filling production lines bring up to 0.1Mpa by original 0.02MPa～0.03MPa, thereby can satisfy the requirement of low speed can and high-speed canning, and can be when discontinuous can by keep-up pressure equilibrium of pressure in the balance tank of automatically regulating, therefore the phenomenon that the can shakiness can not occur, the requirement of filling accuracy can guarantee the filling accuracy of the filling apparatus under disconnected bottle situation again in the time of can guaranteeing continuous can.
By setting up pressure balancing tank, the filling pressure of plastic bottle filling production lines has been brought up to 0.1Mpa by original 0.02MPa～0.03MPa, but cause soup moment in pouring process to overflow when pressure is too big easily, therefore before the can mouth, set up the buffering cup that gas circuit is installed.
The beneficial effect that the utility model had is: a kind of plastic bottle infusion filling device is provided, adopts variable frequency pump to carry soup, carry out variable frequency control according to the fluctuation of fluid pressure in the physic liquor intake tube road to advancing amount of liquid medicine; Set up pressure balancing tank between dilute preparing tank and the bottle placer, can make the filling pressure of plastic bottle filling production lines bring up to 0.1Mpa by original 0.02MPa～0.03MPa, the requirement of low speed can and high-speed canning can be satisfied, and the filling accuracy requirement of continuous can and the can of disconnected bottle can be guaranteed simultaneously; Before the can mouth, set up the buffering cup that gas circuit is installed, can effectively prevent the soup moment spillover that causes because of pressure is excessive in the pouring process.
