(54) FSHTANIZING AIR FRAMEER

1It is related to installations for cooling clinker, the output of the brushes of rotary furnaces during the production of aeMetif ha in the construction industry.

. A known kolovikovy refrigerator, sodetzhaschy case n coposnshsovuyu lattice of.

The closest to the proposed by the meticulous essence and the achieved result is the grate cooler, the contents of the body with inclined side walls on the round, the grate, conveyor for. spills, sharp and general blowers, grate drive. Some of the air heated in the refrigerator enters the furnace and is used to burn fuel, and its excess is emitted into the atmosphere after it has been cleaned in C21 cyclones,

Nbdosgapsam izvestnos refrigeration-, koB. There are overproduced with a large number of parts, requiring a large consumption of alloyed steels, a limited pls of cracks in the grates for the passage of cooling air to the material, large overall dimensions, a large consumption of energy, difficulty in maintenance and repair.

The purpose of the invention is to increase reliability.

This goal is achieved by the fact that the fountain is equipped with a body installed at an angle to the horizon with sloping side walls and round staos, equipped with a triangular reflector with a concave side sides disposed along the entire length of the base of the body.

The gushing aero cooler is adjacent to the hot end of rotary kiln I. It has discharge hatches with grille and screw blades 2, the hot end of the furnace enters the furnace head 3, the refrigerator contains a hot chamber 4, a partition 5, a cold chamber 6, a window 7, a door 8 , unloading hatch 9, collector U, reflector I 1, cooling base 12, slots 13 connected to the collector, mounted hatches 14, refractory lining 15, spray nozzle 16dl of sprayed water supply and threshold 17. The body of the refrigerator is made of sheet steel and is lined with refractory bricks. On the lower base of the housing there is a socket along the entire length of the base into which the reflector II units are installed. The reflector consists of blocks fixed to the base. The blocks are bolted to speed up their replacement when worn. The material of the inclining surface of the reflector in a hot chamber should have a heat resistance, in a cold one - wear resistance. At the bottom of the core in the side walls there are slots for connecting air lines to the collectors. The mine is made with a vertical and adjacent to the furnace head, the lower base of the mine is extraordinary with a threshold of 17. The refrigerator works as follows. From the hot end of the kiln, the clinker enters the shaft of the spouting aero cooler through the grate. If there are large pieces of clinker in the material that do not pass through the grids of the unloading hatches, they move along the furnace and then with the help of screw blades are raised and mixed to unload, while they are crushed by blows when falling on the furnace body. From the mine, the clicker enters the beginning of the hot chamber, where it is picked up by compressed air coming from the collector 10 through the slits 13. Since the reflector 11c is mounted on the base of the housing with inclined lateral flat materials, it moves to the middle of the refrigerator. But since the feces in the base of the casing have one with two stheron slits 13, the material rises up under the action of countercurrent, is intensively washed with air, is cooled and due to the gas expelled nepavieiiiaeT- with air to the inclined walls of the refrigerator again into the air stream. Thus, the cooling cycle is repeated, but since the refrigerator is installed at an angle of 4-6 to the horizon, the material rises perpendicularly to the base with air flow, and then under the action of the component weight it is lowered towards the unloading side and moves to the discharge hatch 9 and - Volume on conveyor for transport to warehouse. The advantages of the proposed refrigerator are as follows. Since the material is in a suspended state, i.e., it gushes with the help of air, the intensity of its cooling increases and accelerates. In addition, the spouting air cooler is economical, easy to manufacture, operate and repair. Claiming an aero-cooling spout containing an angled body with inclined side walls and a round arch, characterized in that, in order to increase reliability, it is provided with a triangular-shaped reflector arranged along the entire length of the lower base of the body with concave sides.
