UA64768C2 - Device for measuring free-flowing materials in small volumes - Google Patents

Abstract

The proposed device for measuring free-flowing materials in small volumes contains a feeding vessel and a measuring vessel. The said vessels are separated from each other by an intermediate damper. The required volume of material in the measuring vessel can be set by an outlet damper that is installed at the lower part of the vessel. Each of the said dampers can be rotated about its horizontal axis by an actuator with a lever transmission. In the measuring process, the dampers alternately open the outlet opening of the feeding and measuring vessels.

Description

The invention relates to devices for dosing loose substances.

A well-known device for dosing liquids (a.s. Me 478193, USSR), which consists of a cylindrical glass and a rod with a piston mounted in it with the possibility of movement. The disadvantage of this device is the impossibility of its use for loose substances, as well as the fact that it is made as a separate device connected to a consumable container.

The invention is based on the task of creating a dosing device that measures the required amount of a substance supplied from a consumable container to a measuring container.

The problem is solved by the fact that in the known device for small-volume dosing of loose substances, which consists of a consumable and a measuring container, according to the invention, the required volume of the measuring container is formed by the disk upper and lower partition, which separates the measuring container from the consumable one.

Partitions are made with the possibility of rotation around the axes lying in the planes of the partitions.

Partitions alternately open and close the expendable or measuring container with the help of an external mechanism that interacts with the levers of the upper and lower partitions. The measuring capacity is connected to the consumption capacity with the help of a transitional cover.

The essence of the invention is explained by the drawing, which shows the general view of the device in section.

The dosing device works as follows.

The measuring container 1 is installed on the consumption container 11 with the help of the transitional cover 12. At this time, the upper partition C and the lower partition 2 are in the initial position: the upper one is closed, and the lower one is open. When the container 11 is tilted, the substance moves and fills the measuring container 1, the upper partition stops the movement of the substance. When moving the main lever b, the lever of the lower partition 5 rotates the lower partition 2 around the axis 10, closes the consumption container, the access of the substance to the measuring container 1 stops, and the lever 4, turns the upper partition C around the axis 9, opens the measuring container, the measured substance is poured out of the measuring container containers When the main lever 6 is released, the spring 13 returns the partitions 2 and З to their initial position.

The edges of the partitions are made pointed to prevent particles of loose substance from grinding between the partition and the walls of the measuring container.

Claims (1)

A device for small-volume dosing of loose substances, consisting of consumable and measuring containers, which is distinguished by the fact that the required volume of the measuring container is formed by a disk upper partition and a lower partition, which separates the measuring container from the consumable one, while these partitions are made with the possibility rotation around axes that lie in their planes, and alternate opening and closing of one or another container by an external mechanism made with the possibility of interaction with the levers of the upper and lower partitions.
