Description

In the known weighing dispensers with alternately filled containers}, the filling value of which depends on the density of the dispensed liquid according to the position of the hydrometer recorded at the moment of the dispenser operation, the smallest dose dispensed to the consumer is determined by the volume of the measured dispenser capacities.

The proposed dispenser is devoid of this disadvantage. The essence of the invention lies in the fact that the dispenser is equipped with a hinged scale, which is installed depending on the density of the liquid, allowing us to produce liquid in quantities smaller than the capacity of cylinders 11.

FIG. 1 shows a diagram of the sliding scale; in fig. 2-a general view of the weight of the dispenser.

The two measuring cylinders 1 of the dispenser are alternately filled with fluid sucked in by means of the ports 2. The stroke of the pistons depends on the density of the liquid dispensed and is automatically controlled by an additional device made in the form of a tank 3 with a drain pipe 4, which ensures a constant filling level and hydrometer 5.

During the operation of the metering unit, the hydrometer is fixed by the gripper 6, the stop 7 of the limiter comes in contact with the hydrometer and, by the latter’s position, limits the stroke of the pistons.

A dispenser for operating the actuator has two handles. Manual 8 adjusts the dispenser (sets the stroke of the pores depending on the density of the liquid), and the handle 9 actuates the working part of the dispenser.

In order to be able to release quantities smaller than the capacity of the cylinders, the dispenser is provided with a dispensing scale H, the scheme of which is shown in FIG. 2. The scale is located in the immediate vicinity of the arrow // of the device and is made in the form of a hinged multi-link system consisting of digitized bars J2.

Since the piston stroke varies depending on the density of the dispensed liquid, the displacement of the recording arrow depends on the same parameter. The implementation of the hinge scale allows changing its length and dividing it to the density of the fluid. Setting the scale takes place automatically, simultaneously with setting the stroke of the pistons. During the installation movement of the pistons, the recording arrow // grabs the outermost scale by the protrusion and stretches it in accordance with the set stroke of the pistons. After that, the links are fixed with the clip 13.

Subject invention

A weighing dosing unit containing two alternately filled cylinders, the filling of which is carried out depending on the density of the dosing liquid, characterized in that, in order to ensure the discharge of liquid in quantities smaller than the capacity of the cylinders, a hinged multilink distributive scale is used that is extensible at the beginning of measurement with the help of the recording flow meter and fixed with a clamp in the set position before measuring the doses.
