Description

one

The invention relates to devices used for the chemical and heat treatment of products, and can be used in mechanical engineering, including agricultural, ferrous and nonferrous metallurgy, chemical industry, etc.

The purpose of the invention is to increase productivity and reduce energy costs.

This goal is achieved by the fact that, in a unit for thermal diffusion doping of products, containing a rotary kiln and a rotating retort with a removable lid, a loading and unloading device for the mixture of the doped and purging gases, the alloying system, the loading and unloading device, sluice chamber adjacent to the unit.

The drawing shows the proposed unit.

The rotary kiln 1 with heaters 2 has a retort 3, which is connected to an insulated block of chambers 6 by means of the transporting channel 4. and a lock device 5. The retort is equipped with reflective elements 7 and is rotated by means of a drive 8. The furnace and the block of chambers are rotary devices 9 and 10, respectively. The retort is closed with a lid. The block has cameras, for example, A and B (according to the number of alloying mixtures).

The lock device can be equipped with a supply unit for the reaction and natural gas.

The device works as follows.

Turning the oven 1 using a rotating device 9, bringing the retort 3 to a vertical position or placing it at a certain angle (the cover of the retort at the top), remove the cover and load the processed products in bulk or fix into the retort Composer V.

sirovanno (in the volume of the retort or in a container). The reflective elements 7 prevent the processed products from entering the transport channel 4 and their design depends on the size and configuration of the processed products.

After closing the lid, turn the oven until the output of the block of chambers 6 to the extreme

top position. Turning the camera block with the help of a pivoting device 10, connect the camera (with the necessary alloying mixture) with its sluice device 5, opening

pour the alloying mixture into the retort. Shutting the lock device, put the oven in a horizontal position, turn on the heating of the oven 2 and drive the rotation of the retort 3.

After conducting thermal diffusion saturation of the first doping mixture, turn the furnace and remove the block of chambers to its lowest position. Opening the lock device,

The light mix is poured (returned) into its cell. Then, turning off the lock device, the furnace is turned, the output of the chamber block to the extreme upper position. Turning

the chamber block is connected to the next alloying mixture with a lock device. Opening the lock device, pour in. retort the next alloying mixture, the removal of which

after the process of thermal diffusion saturation is carried out in a similar way. i The listed operations to replace doped mixtures can. performed while rotating the retort

and its heating is on.

If necessary, during the replacement of the mixture in the retort serves purge gases.

Thus, the proposed device allows multi-component doping of products in various alloying mixtures with almost no loss of performance and higher energy consumption.
