A non-destructive filling equipment and method for colloid containing solid particles

Abstract

The embodiment of the invention relates to the technical field of filling, and specifically relates to a non-destructive filling device and method for colloid containing solid particles. The non-destructive filling device comprises a material storage container, a height regulation device, a semi-closed valve element and a control device. A filling opening is formed in the bottom of the material storage container. The height regulation device is installed on the material storage container and used for regulating the height of the material storage container. The semi-closed valve element is installed in the filling opening. The section area of the semi-closed valve element is smaller than the section area of a filling passageway. The control device is in signal connection with the height regulation device and the semi-closed valve element and is used for controlling the actual height difference between the top face of the colloid, containing the solid particles, in the material storage container and the filling opening to be smaller than the height difference set value when the filling opening is in the semi-opened state. The non-destructive filling device cannot generate residues inthe opening and closing process of the filling opening, and it can be avoided that overflow contamination is generated at the position of the filling opening.

Description

technical field [0001] The present application relates to the technical field of filling, in particular, to a non-destructive filling equipment and method for colloid containing solid particles. Background technique [0002] In the prior art, when the colloid containing solid particles is filled by a DC filling machine, the filling flow is generally controlled by opening and closing a valve arranged at the filling port of the DC filling machine. In the process of valve switching, it is unavoidable that the valve core squeezes the solid particles in the colloid during the opening and closing action, resulting in particle debris in the finished product, which affects the aesthetics of the product and makes the product unable to achieve the expected vision.

Problems solved by technology

In the process of valve switching, it is unavoidable that the valve core squeezes the solid particles in the colloid during the opening and closing action, resulting in particle debris in the finished product, which affects the aesthetics of the product and makes the product unable to achieve the expected vision. Effect

If the valve is kept in the normally open state during the filling process, when the empty bottle is switched during production, the colloid will always overflow due to the normally open filling port, which will easily cause contamination of the bottle mouth, conveyor belt and machine parts, and serious Violation of the GMP (Good Manufacturing Practices, Good Manufacturing Practices) standards of the daily chemical industry, so that the products cannot meet the qualified standards

[0003] To sum up, the existing DC filling machine will produce a large amount of debris during the opening and closing process of the filling port, and the cancellation of the valve core switch will cause the problem that the filling port is always open and prone to overflow pollution
