The invention relates to a packaging and dosing technique and can be used in the food and chemical industry.

The purpose of the invention is to simplify the design and expand the range of adjustment of the device.

Placing an additional ring between a permanent magnet and an electromagnet weakens the interaction of the fields of the ring magnet and sjieKTpoMarHHTa.

Figure 1 shows the dispenser, a vertical section; figure 2 - the same position; fig.Z - electromagnet measles.

The dispenser includes a hopper 1, a cylindrical case 2 located under it with a measuring chamber 3, and a volume control mechanism for the measuring chamber 3 with an emanating from a constant ring magnet 4 mounted on the case 2 with the possibility of axial movement and a magnetic MF file located inside the case 2 Ogre Znchitelem 5 level height of the measuring chamber 3, made in the form of a sleeve with a hole, which is the outlet opening of the measuring chamber 3.

The outlet of the metering chamber 3 is blocked by a conical flap 6, made of a non-magnetic material and placed above the level 5 height limiter.

The valve 6 is driven in the form of an electromagnet 7, also mounted on the housing 2 under the ring magnet 4. The armature 8 of the electromagnet 7 is connected to the non-magnetic valve 6 with a non-magnetic 1 rod 9, made with the possibility of moving it along the housing 2 relative to the core 8 to controlling the operation of the electromagnet 7, for which the connection of the rod 9 with core 8 is threaded. To lock the rod 9 against 8 after adjustment, use the locknut 10.

To weaken the interaction of the fields of the ring magnet 4 and the electromagnet 7 between the latter, there is a ferromagnetic ring 11, which is simultaneously one part of the magnetic conductor for the magnetic flux of the electromagnet 7. The second part of the magnetic conductor of the electromagnet 7 is the ferromagnetic glass li.

A nonmagnetic sleeve 13, for example made of bronze or stainless steel, is pressed into the hole of the coil of the electromagnet 7 before it is wound to prevent the cylindrical part of the coil frame from bending when it is wound

To exclude magnetic sticking of ferromagnetic core 8 to ferromagnetic limiter 5 after switching on and subsequent switching off of electromagnet 7 on core 8 from side of limiter 5 nonmagnetic IT 14 is pressed, limiting the course of core 8 to a value sufficient to eliminate said sticking after turning off electromagnet 7.

In the lower part of the housing 2, a cut-off module is installed, consisting of an electromagnet 15, its valve 16 interacting with a cone 17 connected to a non-magnetic holder 18 having through-passages similar to the passages of the core 8 (Fig. 3).

The value H is indicated adjustable height of the measuring chamber 3.

With the position of all the elements (Fig. 1), the device is in the initial state; electromagnets 7 and 15 are turned off, their moving parts are lowered to the stop with corresponding elements under the action of their own weight, measuring chamber 3 is emptied.

With the position of all elements of the device indicated in Fig. 2, the latter is in the switched on (intermediate) operating state; electromagnet 7 is turned on, measles 8 is drawn into its cavity, valve 6 is raised above limiter 5, the inlet of the measuring chamber 3 is open, bulk material enters the measuring chamber 3

The dispenser works as follows.

The electromagnet 7 is supplied with a control voltage U ", npi, as a result of which it is triggered by pulling the measles 8 into its cavity and pushing the conical valve 6 upwards through the rod 9 (Fig. 2). When moving upwards, measles 8 with a rather large force strikes with sleeve 14 along the lower part of limiter 5.

In this case, the conical flap 6, overcoming the resistance of the bulk material, moves away from the limiter 5, opening the inlet to the metering chamber 3, into which the bulk material begins to flow.

By filling the measuring chamber 3, the electromagnet 7 is turned off, and the electro31

magnet 15 is turned on by applying a control voltage to it.

Since the measuring chamber 3 is filled with bulk material, when the electromagnet 7 is switched off, the position of its moving part does not immediately change, since the bulk material impedes this.

When the electromagnet 15 is turned on, the valve 16 is drawn into its cavity, moving away from the cone 17, as a result of which the gap formed by the cone 17 and the lower part of the electromagnet 15 opens. The gap is the outlet of the metering chamber 3.

The bulk material begins to flow out of the metering chamber 3, more and more overlying layers of bulk material are drawn into the flow. When loose material particles surrounding the flap 6 are drawn into the flow, it begins to fall under its own weight together with the bark 8. After reaching the contact with limiter 5, the shutter 6 stops, thus blocking the inlet to the measuring chamber 3 and thereby terminating access to the latest bulk material.

17

After that, the electromagnet 15 is turned off, as a result of which its valve 16 is lowered under the action of its own weight until it contacts with the cone 17, thereby blocking the outlet opening of the metering chamber 3. This completes the cycle of operation of the device. All subsequent cycles are repeated in the same way.
