Description

A kind of CL filling apparatus being easy to medicinal liquid backflow

Technical field

This utility model relates to fill field, is specifically related to a kind of CL filling apparatus being easy to medicinal liquid backflow.

Background technology

In food pharmaceuticals industry, utilize filling apparatus that liquid is carried out fill to popularize very much, the top of filling apparatus is provided with feed tube, bottom just liquid is provided with many filling tubes, being respectively equipped with upper and lower two liquid level limit induction devices in filling apparatus, when liquid level arrives the liquid level limit induction device of bottom when, system controls feed tube feed liquor, when liquid level reaches the liquid level limit induction device on top when, system controls feed tube not feed liquor.In order to improve the fill efficiency of liquid, it is typically all and uses while fill, carry out the transmission of container, this is accomplished by the distributed about of filling apparatus many filling tubes, additionally the transmission track of container needs to match with the filling tube rotary motion trace of allotter, and the transfer rate of container is identical with the speed of filling tube, then by system control flow or time, the valve of filling tube is opened and closed.

But in actual production process, this liquid precision away from the filling apparatus fill of structure is the highest.Research through technical staff finds, it is not constant that problem goes out the liquid level at filling apparatus liquid, liquid level can change, in result in filling apparatus, liquid is different for the pressure of filling tube, and, the when that liquid adding, directly add facing to the liquid level of liquid in filling apparatus, owing to feed tube is, by pressure apparatus, the liquid in device for storing liquid is flowed into filling apparatus, so the liquid flowed into can produce the biggest fluctuation to the liquid levels in filling apparatus, the change of liquid level and the fluctuation of liquid level all can cause the flow velocity in filling tube highly unstable, so it is the highest to result in filling accuracy.Although the product-filled probability gone wrong is the highest, but owing to food pharmaceuticals industry is inspected by random samples for the product needed dispatched from the factory, once inspects out undesirable product by random samples, the product of whole batch all can not dispatch from the factory, and the loss causing enterprise is bigger.

It is, by pressure apparatus, the liquid in device for storing liquid is flowed into filling apparatus additionally, due to feed tube, and can be with gas in pressure apparatus, if the liquid bottom that the liquid outlet of feed tube is arranged in filling apparatus, can make have a large amount of gas to emerge in liquid in filling apparatus, the liquid level making liquid on the contrary is unstable.

The patent of entitled " avoiding the CL filling apparatus of liquid waste " that the applicant applies on the same day, solve the problems referred to above, but owing to the bottom sides of annular retaining ring is along the bung less than end bucket, and the liquid level in end bucket flushes with bung, so being positioned at the air exclusion inside and outside annular retaining ring between end bucket and bung, owing to respiratory organ is in the range of annular retaining ring, so when the overflow medicinal liquid in overflow launder liquid level higher than end bucket flange outer side edges along when, it is positioned at the space outside annular retaining ring between end bucket and bung and forms confined space, the backflow of overflow launder inner liquid medicine can be affected.

The patent of entitled " ensureing pressure balanced CL filling apparatus " that the applicant applies on the same day, solves the problems referred to above, but owing to the structure of annular retaining ring is complicated, so processing and manufacturing is comparatively laborious, production cost is of a relatively high.
