Problems solved by technology

[0002] Filling is an essential link in the production process of beverages, liquid medicines and other liquids. Currently, the commonly used filling method is mainly piston filling, but the piston filling has the following disadvantages: 1. The reciprocating movement of the piston will cause the piston and There are different degrees of wear on the sealing part, which will affect the filled liquid and affect the product quality; 2. The residue of the liquid medicine in the sealing part of the piston usually makes the filling device difficult to clean and cross-contamination; 3. For suspension Liquid filling, the liquid medicine cannot be continuously circulated during filling, and the suspension without circulation will have unstable components, such as concentration changes, sedimentation, etc., which will affect the filling quality
Currently commonly used filling equipment, the suspension cannot be in a circulating state all the time, resulting in changes in the concentration of the suspension during the filling process. Inconsistencies in the concentration of the suspension will affect product quality
[0004] To sum up, it can be seen that a new type of suspension filling device is currently needed to solve the problem that the suspension cannot be in a circulating state when filling, so that the concentration is uniform and the product quality is stable

Abstract

The invention discloses a filling device special for an injectable suspension. The filling device comprises a dosing device, a dosing control valve and a filling head. The dosing device comprises a piston booster device and a dosing cavity. A dosing cavity inlet and a dosing cavity outlet are formed in the lower part of the dosing cavity. The dosing cavity is connected with the filling head. The dosing control valve is a three-way valve and comprises two inlets and a liquid outlet. One of the inlets is connected with the filling head. The other inlet is connected with the dosing cavity outlet.The filling head is internally provided with a control valve set. A liquid inlet, a dosing cavity connecting opening, a dosing control valve connecting opening, a filling opening and a liquid discharging opening are formed in the filling head. The dosing cavity connecting opening in the filling head is connected with the dosing cavity inlet. The dosing control valve connecting opening is connected with one inlet of the dosing control valve. The liquid discharging opening is controlled to communicate with the filling opening through a piston. A filling container is arranged at the lower part of the filling opening. Liquid can be made to be always at a circulation state in the filling process, the consistency of concentration of the injectable suspension is ensured, the filling quality is ensured, and a non-mixed suspension liquid can be filled.
