Description

The invention relates to equipment for the dosing of flowing materials.

The purpose of the invention is to improve the metering accuracy and reliability by ensuring uniform flow of bulk material into the working chamber.

Figure 1 shows the proposed dispenser, a longitudinal section; figure 2 is a section aa in figure 1.

The dispenser contains a feed hopper 1, under the outlet opening 2 of which coaxially mounted working chamber 5 covered by electromagnetic coils 3 and 4 with spherical ferromagnetic bodies 8 placed between horizontal interchangeable grids 6 and 7. Above top 6 grid evenly over the cross section of working chamber 5 additional ones are placed ferromagnetic bodies 9 mounted rotatably on parallel horizontal axes x 10. The latter are fixed in three horizontal bridges in a checkerboard pattern. Additional ferromagnetic bodies 9 are installed on the wasps x 10, also in a checkerboard pattern.

The dispenser works as follows

When the coils 3 and 4 are included in the network, they create an electromagnetic field that drives the ferromagnets 1 and 8 and 9. The dosing material in the bunker 1, due to the rotational motion of the magnetically hardened bodies 9 and the first weight passes through the system of Rus formed by the axes 10 located in three horizontal planes with the ferromagnetic bodies 9 mounted on them, and spills onto the upper grid 6, whence under the action of oscillatory motion of the ferromagnetic

The bodies 8 and under the action of their own weight wake up through the holes in the grids 6 and 7. The flow rate of the dosed material can be smoothly controlled by changing the living section of the interchangeable grids 6 and 7 and the magnetic field induction, and with increasing magnetic field induction the dosing accuracy increases. The installation of two electromagnetic coils 3 and 4 makes it possible to match the rate at which the dosing material enters the upper grid 6 with the speed of its release through the lower grid 7.
