Description

The invention relates to apparatus for dispensing bulk solids and liquids, consisting of a funnel with barriers for separate components and a rotating drum with compartments. In the proposed apparatus, the drum installed under the funnel is equipped with cylindrical cavities with pistons, which serve for measuring the liquid, The amount of fluid measured is adjusted by a set screw. For mixing the bulk in the funnel, in the latter are placed the agitators, driven by a pull from the eccentric sitting on the shaft. In order to signal the absence of one of the branches of the funnel bulk used movable and fixed electrical contacts.

In FIG. 1 depicts a top view of the apparatus; FIG. 2 is a section along line AB in FIG. one; FIG. 3 shows a section along the line of the LED in FIG. one.

The drum 1 (Figs. 2 and 3) is placed on the shaft 2, with which it rotates from the drive pulley 3. The shaft 2 rests on the brackets 5. A funnel b, which has compartments with forward vanes 7, is fastened above the blade of drum 1. the sleeves receive material for dosing. Due to the rotation of the drum 1, a layer of material of a certain thickness is placed on its web from each funnel section. The thickness of the material layer is controlled by approaching or moving away from the web of the gates 7. Next, the metered material moves along channel 8, where it is subjected to mixing by blades 10 (Fig. 1) located on channels 8 in a checkerboard pattern, and finally goes to its destination. To signal a shortage of materials in one of the compartments of the funnel 6, automatic electrical signaling 11 is used, consisting of a moving contact 12 and a fixed contact 14 placed for this in the funnel b of the material filling the funnel, contact 12 is attached to its front wall. In the absence of materials in one of the sections of the funnel, contact 12 becomes vertically connected to contact 14 and the alarm circuit is closed.

In order to prevent materials from getting stuck in the compartments of the funnel, they are shaken by the mixers 16, which are connected by means of tampers 17 with eccentrics 15 of the Nazal 2. The mixers 16 receive up and down movement through this gear, which results in the flow of loose components.

For dispensing liquids in drum 1, at the locations of the spokes.

there are cylindrical cavities 18 provided with pistons 19, wherein each pair of opposite cylindrical cavities is connected by a channel 21. Each cylindrical cavity separately has a channel 20 that connects it at the lower position of the channel to the receiving pipe and at the top of it to the discharge pipe . The axis of the shaft 2 is hollow and has a blank partition 22 in the middle of the drum. On each side, tubular axes 23 and 24 are inserted into the hole of axis 2, which have internal channels 25 and 26. The semi-axle 23 is connected to the discharge water pipe 7 and the semi-axle 24- with discharge a pipe; both axles are stationary while rotating the drum, which, at the direction of the author, makes no more than 10 revolutions per minute.

The liquid enters through the semi-axis 23 into its front part 27 and through the channel 20 into the cylindrical cavity 18 below and presses on the piston 19, behind which there is also a liquid, which causes pressure to be transferred to the upper piston 19, which pushes the liquid out of the upper cylindrical cavity channels 28, 25 into tubular semi-axis 24.

The stroke of the pistons 19 and, consequently, the capacity of the cylinders is adjusted by set screws 29. Before the piston 19 is in its lower position, it is pressed into the set screw 29, the valve stem 30 is preliminarily inserted into this B1INT and opened by a certain amount in order to regulate the filling constant on the back side of the pistons 19. The valve 30 is pressed by the springs with such force so that they do not open from the pressure on their area at the top position of the cylinder 18.

When the drum 1 rotates, each cylinder 18 is turned on into the discharge pipe, then into the discharge pipe, which results in an uninterrupted flow of liquid in the discharge pipe (tubular doloosi). The fluid pressure in the discharge pipe should be slightly lower than in the injection and the difference between these pressures should be greater, the faster the drum 1 rotates.

The subject matter of the invention.

1. A dispenser for dispensing bulk solids and a liquid, consisting of a multi-compartment funnel and a rotating drum, characterized in that the drum 1 installed under the funnel b is provided with cylindrical cavities 18 with pistons 19 serving to measure the liquid, coming through the channel 26 of the tubular half-axis 27, then through the channel 20 in the hub of the drum 1 with the outlet through the channel 28, also in the hub of the drum 1, and through the channel 25 of the tubular semi-axis 24, with diametrically opposite cylindrical cavities 18 connected by channels 21 for bypassing the liquid from one cavity to another when moving the pistons 19, one under the action of the incoming liquid, and the other pushing out a measured liquid, the amount of which is regulated by a set screw 292. The use of agitators 16 driven by eccentrics 15 on the shaft 2 using t g 17.

3. The use of electrical contacts-movable 12 and fixed 14, specified in p. 1, gives the connection for the purpose of giving a signal in the absence of a loose b in the funnel compartment and turning the contact wing 12.
