JPS5946876B2 - ``Ten'' valve for filling mixed liquid such as fruit pulp - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates in particular to a filling valve for liquids mixed with solids such as fruit pulp.

Even if the liquid mixed with solids such as fruit grains and pulp is uniformly stirred and mixed in the tank using a stirrer, etc., the filling valve tube protrudes downward from the tank in a pocket-like manner, and the flow path is narrow, so it is the same as inside the tank. Not only is it extremely difficult to maintain a mixed state, but especially when the specific gravity of the liquid and solids such as fruit grains and pulp is different, these solids may float outside the filling valve or conversely cause the filling valve to close. As a result of precipitation in the cylinder, variations in mixing with the liquid become even more pronounced, and there is a defect that a mixed liquid of uniform density cannot be filled.

The present invention improves the defects in the filling valve for filling liquid mixed with solids such as fruit grains and pulp, and enables filling of a homogeneous mixed liquid. The main feature is that a check valve is provided at the inlet of the filling valve, which opens and closes simultaneously in conjunction with a flow valve cylinder slidably fitted to the lower end of the filling valve.

An embodiment of the present invention will be described with reference to the drawings. A filling valve cylinder 3 protruding from the bottom of a tank 2 having an agitator 1 includes:
A valve cylinder 4 fixed to the tank 2, a flow valve cylinder 6 slidably fitted inside the lower part and urged downward by a spring 5, and a flow valve cylinder 6 that supports the lower end of the flow valve cylinder 6 and has an upper part. It is composed of a spreader 8 integrally formed with a vent tube 7, and a seal pad 10, which is in contact with the rim of the filling container, is fitted and fixed on the outer side of the lower end of the flow valve cylinder 6 via a spacer 9. A seal ring 11 is provided at the lower end support portion of the flow valve cylinder 6 at -8.

In addition, a check valve 13 is fitted at the inlet of the filling valve cylinder 3, that is, at an intermediate position of the vent tube 7 corresponding to the bottom surface of the tank 2, which is biased downward by a spring 12 and opens and closes the upper end of the valve cylinder 4. The check valve 13 is supported at the upper end of the flow valve cylinder 6 via a support frame 14 provided at the lower part thereof, and is formed to open and close simultaneously in conjunction with the opening and closing action of the flow valve cylinder 6.

However, closing the check valve 13 in the present invention is sufficient to prevent solid matter such as fruit grains and pulp from flowing down into the filling valve cylinder in the mixed liquid, and does not necessarily mean complete closure. .

In addition, 15 in the figure is a vent tube support arm. In the embodiment of the present invention, a check is made when the mouth edge of the filled container lifted up by the Karali lid configured as described above comes into contact with the seal pad 10 and the flow valve cylinder 6 is raised against the spring 5. The valve 13 is also opened against the spring 12 to open the tank 2.
The solid mixture in the filling valve cylinder 3 is filled into the filling container, and when the filling container is lowered and the flow valve cylinder 6 is returned to the spreader 8 by the spring 5 and closed, the check valve 13 is also filled. It was closed by Hatsujo 12,
The inside of the filling valve cylinder is sealed from the tank 2 for a certain period of time in preparation for the next filling operation.

In the present invention, a check valve that opens and closes simultaneously with the flow valve cylinder is provided at the inlet of the filling valve cylinder protruding from the bottom of the tank, and the filling valve cylinder is sealed from the tank after filling is completed, so that fruit particles, pulp, etc. This prevents solids from settling into the filling valve cylinder from inside the tank or floating up from the filling valve cylinder into the tank, making the density of the mixed liquid to be filled uneven. It has the excellent feature of being able to fill a homogeneous mixed liquid with a constant ratio of mixed solids and liquid.
