Description

The proposed mortar preparation system according to the invention consists of a length of pipe 1 (see drawing) within which shaft-pipe 2 with screw and blades 3 rotates. Producing displacement and mass transfer in diaphragm 4.

Aperture 4 is a disc with a hole in the middle. The purpose of the diaphragm is to reduce the cross section of the passage from one zone to another, thereby creating resistance to the passage of the mass “to increase its pressing in the first zone.

The second zone is a nozzle-sieve, the walls of which have a grid S, resting on a rigid frame 6. Inside the nozzle, the scrapers 7 located along a helical line rotate on a common shaft rotate on a separate coupling. Scrapers, as they wear out, can move radially. Under the nozzle is a sieve pocket 8 for collecting stones. The stones pressed by the scrapers 7 get into the karma and are forced out the solution and from the latter. As the pocket is filled, with the help of the gate 9 are discharged to the side through the sleeve 18.

The solution, rubbed and pressed through a nozzle sieve, flows into

collector 19. The stones are collected in a separate collection where they are washed with water using the washed solution.

The shaft 2 has a pick-up for sealing the shaft 2. The axial force is sensed by the thrust bearing 11. The screw drive 12 is conventionally received worm gear. Water is supplied through shaft 2 using a conventional gland / 5 and tap 14 to regulate the water supply. The holes 20 for the exit of water to the shaft 2 at the diaphragm 4 are covered with brushes 21, as in the mouthpiece of a brick press.

The dosage of the components is done on shelf 15, which is at the level of the hopper 16. The components are layered on a layer of thickness proportional to the composition: alabaster (cement) 24, lime mortar 23 and sand 5. Then, using a scraper 17 or a spade, a vertical blend is made the masses, unloading it into the receiving box 16, make sure that all the layers fall simultaneously.

Separate water supply to the first zone is not required, as water is needed to wet the sand and alabaster (cement) in the dosing drawer, as well as in the lime paste.

The bearing on the other end of the shaftwork (at the nozzle-sieve), as experience has shown, is not needed.

If it is not necessary to grind the solution through a sieve and add water to the mixture. Gateway 9 is removed, and the device operates as a single-zone mixer, dispensing mass through a pocket for stones and sleeves. The aperture can be changed.

The subject matter of the invention 1. A device for preparing a mortar with a mixing chamber for dry components, in which vras, agitating mixing blades are located, in the form of an auger, characterized in that a mesh wiping chamber of known construction with wiping blades is attached to the mixing chamber, separated from the mixing chamber by an annular diaphragm provided for intensifying the mixing of the components entering the wiping chamber.

2. A device according to claim 1, characterized in that the mixing wiping blades are mounted on a single hollow shaft passing through both chambers and having openings on its part located in the wiping chamber, which serve to supply water to. cleaning chamber.
