The invention relates to devices for loading powder and liquid components of ceramic masses and can be used in engineering and other industries.

A device for feeding materials is known, which contains a double-walled casing: an outer, two-part, -and an inner elastic sheath, a loading and unloading branch pipe, a choke connecting to a vacuum source. Inside the case there is a rotary drum, 1.

This device can supply only one component. To ensure the technological process, it is necessary to install devices on the mixer according to the number of components, for example, for a solvent, a binder, and a resin. Installing three devices, opening the valves for supplying liquids and the mixture to the mixer is laborious and reduces the life time of solid mortar solutions. Separate flow of the liquid and the mixture into the mixer does not provide continuous wetting of the solid phase to, therefore, high-quality promes. The device also does not provide the dosing supply of components to the mixer, which causes uneven operation of the drive, large starting points, which overestimate the required power of the equipment.

The closest to the invention to the technical essence and the achieved result is a device for dosed supply of bulk and liquid materials, containing a conical bunker for bulk material, a container for liquid materials with an outlet 12}.

However, the known device is characterized by a lack of uniformity in the supply of bulk and liquid material, since the size of the trickle of the conical hopper is regulated with the power of the eccentric mechanism, and it is difficult to achieve a uniform yield of bulk material.

The aim of the invention is to improve the uniformity of the flow of materials and their mixing.

This goal is achieved by the fact that in the device for the dosed supply of bulk and liquid materials containing a conical hopper for bulk material, a container for liquid materials with an outlet, a compartment is installed in the hopper with the possibility of vertical reciprocating movement of the rod with a conical tip, a conical support is fixed outside the bunier with a gap, the device is equipped with additional containers for liquid materials with outlet pipes, all containers for liquid materials are flexible The shells are installed between the hopper and the support, with the outlets being a perforated annular tube divided by partitions into compartments, the number of which corresponds to the number of shells, with the apertures of the tube overlapping the conical tip.

FIG. 1 shows a device for dispensing bulk and liquid materials, vertical section; in fig. 2 - node 1 ya of FIG. 1 in FIG. 3 is a section A-A in FIG. 1; in fig. 4 - section BB in figure 1.

The device contains a conical bunker 1, outside of which a conical support 2 is mounted, between them with a gap are located, adjacent to them flexible shells 3 with inlet ports MHi 4 and outlet nozzles made in the form of a perforated annular pipe 5 with drainage holes with a diameter of 3. The perforated tube 5 is overlapped by a conical tip b with the strain 7, on which nuts 8 are installed, adjusting the lowering of the rod 7 with the tip 6. The rod 7 passes through the sleeve of the cover 9 and can be fixed with a pin if necessary. The charge is charged through the loading nozzle 10. The cone bearing 2 is held by a ring 11, on which a ring 12 is installed, welded to a perforated pipe 5. The nozzle 4 is blocked by plugs 13. The feeder has at least two flexible shells 3: a solvent and a binder. The perforated pipe 5 is divided by partitions according to the number of flexible shells.

The principle of operation of the device is as follows.

Source components by loading, g into the case and flexible shells. Install the ycTpoftcTjBo into the support ring of the mixer using a crane beam for the rod ring 7 "Under the influence of the weight of the charge, the conical tip 6 is lowered until the adjusting nuts 8 come into contact with the crack bushing 9. The drain holes are formed and an annular gap forms between the pipe 5 and the tip b. The liquid flowing out through the openings of the pipe 5 forms a rain curtain through which the particles of the charge fall into the mixer. As the fluid flows out of the flexible shells 3, the hopper, together with the charge, moves downward, creating additional pressure in the flexible shells, since the support 2 is fixed with a stop ring of the mixer. Under the action of this pressure, the liquid components expire through the drainage holes, forming a multi-component shower formed by the solvent, binder, and other liquid additives. The dry components in the form of individual particles, the passage through the complex shower are also moistened in a complex manner. Each particle, passage through a complex shower, takes with it a particle of solvent, a particle of a binder, and parts of other additives.

for example, a solution of salts that, already in flight to the mixer, begin a reaction between themselves and the dry particle. This is especially important for fast-hardening ceramic materials.

The proposed device provides multiple feeds to the mixer of dry components with different liquid components: solvent, binder, and salt i solutions.
