Description

one

The invention can be used in the building materials industry and in construction.

Devices are known for preparing building mixtures, for example, ground, processed in a mite, including a housing, a ground flow disperser, dispensers of liquids in a bitumen, water dispensers, liquid and powder milling, a discharge conveyor.

The purpose of the invention is to improve the quality of the mixture and eliminate dusting.

This is achieved by the fact that over the free end of the unloading conveyor an additional conveyor is mounted at an angle to it in the direction of unloading, and the nozzles of the powder-in-feed are made with the suction nozzles placed inside the housing.

The drawing shows the proposed device.

The device comprises a housing / on which a dispersant of the ground flow is mounted, made in the form of outer 2 and inner 3 pivotal rotary drums, water dispensers (or other additives) 4, liquid 5 and powder 6 in the miter, dispensers 7 blister in the miter. For feeding into the housing / raw mineral material, a conveyor 8 is installed above the latter.

with a damper 9. A pneumatic system for spraying powdered powder by means of nozzles 6 has suction nozzles 10 located in pockets 11, air ducts 12 connecting spray nozzles with centrifugal fans 13. In the lower part of the device, a discharge conveyor 14 is installed, the charging port 15 of which connected to the body / fabric cover 16. Above the free end of the unloading conveyor 14, an additional conveyor 17 is mounted at an angle to it in the direction of unloading so that its bottom vb forms with the upper branch of the discharge conveyor 14 a cavity having a wedge-shaped lead-in part 18 and a working slit 19.

The device works as follows. Raw mineral material for example

the soil is fed by a scrap conveyor belt 8 to the damper 9, from which it falls into the surface of the outer drum 2 of the dispersant, which is defined by the position of the damper. Core drums 2 and 3

rotate in opposite directions and disperse the ground flow in housing J. The adjustment of the ground flow characteristic across the width of the housing is carried out by varying the revolutions of the outer drum 2 and

the position of the flap 9. When hit on

the drum rods of large, non-crushing particles, the latter are removed from the processing zone outside of the housing -1. A dispersed stream of liquid is introduced into the formed distributed soil tray through the nozzles 5. The powdered substance is dosed out with the help of dispensers 7 and is sprayed by the air directed air flow from the nozzles 6 and created by the fans 13. To prevent dusting from the housing / suction nozzles 10 are located inside it in the pockets 11 protecting the air system from the loops and large particles of the mixture. Sprays 6 loroshkoobraznyh in the living have corresponding suction nozzles 10, arranged in a cross-pattern. Humidification of the mixture to the optimum: Humidity; ness is carried out using a group of nozzles 4. Mixing the components of the mixture in the intersection zone. Directional flows are accomplished by facilitating the contact of particles on their surfaces and controlling the mutual penetration of particles into the fluxes of a stream and speed. Three ashes of input into the device in the housing allow the user to inject into the device in a different technological sequence (liquid + powder, powder + liquid), which is necessary to obtain

quality mixtures "and the base of the complex in the know. The finished mixture is unloaded by a belt conveyor 14, the charging port 15 of which is sealed with a fabric cover 16. To destroy the secondary aggregates of the mixture, the latter is subjected to a passage through the wedge-shaped lead-in part 18 and the working gap 19 to abrasion. The auxiliary conveyor 17 rotates at a greater peripheral speed than the unloading conveyor 14. Due to this, the material is drawn into the wedge-shaped lead-in part 18, compacted and then worn out in the working slot 19.

Subject invention

A device for the preparation of building mixtures, for example, soil, treated in the mite, including a housing, a dispersion of ground flow, powder dispensers

in biting materials, sprays of water, liquid and loroshkoobraznyh in biting, unloading conveyor, characterized in that, in order to increase the quality of the mixture and eliminate dusting, above the free end

the discharge conveyor is mounted at an angle to it in the direction of unloading the additional conveyor, and the sprayers in the road are made with suction nozzles placed inside the housing.
