co Stock Device refers to foundry. A known installation for molding and knocking out boxes, containing a table with a grating. The disadvantage of this installation is low labor productivity due to the large amount of manual operations involved in manual rubbing of the sintered pieces of alumina and its sieving into the container located along the grating, in manual embossing and forming boxes A known installation containing a vibrating table with a knockout grille Y. The disadvantages of the known installation are the large labor intensity and low labor productivity, due to the low mechanization of the knockout and molding processes, the large losses of scarce alumina during manual transfer and at the local air vent (in the shop ventilation system is carried away) , 8 kg / h of alumina), as well as high costs for the device shop ventilation. The purpose of the invention is to reduce operating costs. This goal is achieved in that the installation for forming and knocking out boxes, containing a vibrating table with a knockout grill, is equipped with a discharger disposed above the shaking table, a driving eccentric screen at the exit of it, and a dispenser with a level sensor, a rotating arm associated with it, and also fixed under the vibrating table, located in the lower part of the bunker by a roller crusher and a jet pump connected by a conveyor pipeline with a discharger, and placed in the vibrating table by a manipulator and ventilation system In addition, the ventilation system is designed as an interconnected ventilation unit, a ventilation duct and a tank for collecting millet alumina. Figure 1 schematically shows the proposed device, a General view; figure 2 is the same, side view. The installation contains vibrating table 1c arranged in a technological sequence with a knockout grill 2 mounted on a vibrator 3, with 4 slide vibrator guides located under the bunker 5 vibrating table, an electrically driven roll crusher 6, a jet pump 7 transporting pipeline 8 connecting the units located under the vibrating table 1 with a discharger 9, an eccentric screen 10 with an electric drive, a dispenser ll with a level 12 sensor and a rotary sleeve 13 located above it. The ventilation valve contains a ventilation box 14, the ventilation unit 15 and the air duct 16. In the zone of the vibrating table 1, there is a manipulator 17 with a pneumatic cylinder 18, a control panel 19, a duct 20 with filling. The device works as follows. From the heat treatment site (not shown) to the installation for forming and knocking out boxes, a cart (not shown) is supplied with the backfilled boxes 20 installed on it. By the manipulator 17, the box 20 is removed from the trolley and transferred to the knockout position over the vibrating table 1. Suitable rods are removed and placed in a special container for finished products. The vibrator 3 is turned on, and the alumina spills into the hopper 5, from where it enters the roller crusher 6, where the alumina pieces are milled. Alumina from the roller crusher enters the receiving chamber of the jet pump 7, from where through the mixing chamber and the diffuser enters the conveying pipeline 8, through which it lifts into the upper part of the installation to the discharger 9 and from it to the eccentric sieve 10. The eccentric sieve separates the fragments of rods and uncrushed pieces of alumina into a special tray, from which the whole mass flows into special containers (not shown). The processed alumina enters the dispenser AND with the sensor 12, which gives the command to the control panel 19 to turn off the roller crusher 6 and the jet pump 7 when the dispenser 11 is filled. The molding process is carried out as follows. From the control panel 19, a command is issued to open the electromagnetic gate of the dispenser I1, and the alumina enters the duct 20 through the rotary sleeve 13. The sleeve 13 is rotary to release the working area

table with the operation of knocking boxes. After the box is filled with alumina, the vibrator 3 of the vibrating table I is turned on and shaken with compaction of the mass, after which the box, filled with the manipulator, is placed on the cart, which is transported in the heat treatment area.

From the working area of the vibrating table 1, the dusty air is sucked away by the ventilation duct 14 to the ventilation unit 15, which has a set of bag filters and an agitator. / In the ventilation unit 15, the air is cleaned from alumina and leaves it. The alumina collected by the filters, when they are shaken, enters the container located in the lower part of the installation, during filling of which it is removed and emptied directly onto the vibrating table 1 of the installation. This alumina is involved in the process again.

A duct 16 connected to the upper part of the discharger 9 is connected to the ventilation unit 15. It takes the exhaust air from the jet pump after it is cleaned of alumina by the discharger 9 to the ventilation unit 15 for final cleaning.

In the proposed device, labor-consuming manual operations are performed by a manipulator. Alumina soil gap decreases as there is a draw from the workplace. At the same time, expensive alumina is not carried away with the air into the atmosphere, and, by means of a dust extraction plant, is collected in this plant and used again in production.

The technical advantages of the plant make it possible to improve the working conditions of the workers and reduce operational costs.
