Abstract

The invention is aimed at improving the efficiency of the refrigerator. For this, drum 1 contains a coil 5, made on the outer surface of the coil, made of half pipes, welded to the drum side shell. The coil 5 by means of pipelines 6, the pump 7 and the double-channel swivel coupling 8 is connected to the coil 9 placed in the heat exchanger 10 in a single closed loop. The water in the coil 5 is heated through the internal channel of the rotary coupling 8 enters the coil 9 of the heat exchanger 10, where the heat of the water is transferred to another liquid. The water cooled in the coil 9 through the pump 7 and the outer channel of the coupling 8 flows back into the coil 5. 3 Il.

FIG. g

This invention relates to a technique for cooling bulk materials using drum coolers and can be used in the alumina and cement industries.

The purpose of the invention is to increase the efficiency of the refrigerator.

FIG. Figure 1 shows a drum cooler, a longitudinal section, and a circuit for heating and cooling circulating water; in fig. 2 - two-channel turning coupling, longitudinal section; in fig. 3 is a section A-A in FIG. one.

The drum cooler contains the top steel drum 1 with a load of 10

fuel in the furnace. The air is heated and carries with it a portion of the heat of the material back to the furnace. Another part of the heat through the walls of the drum 1 is transferred to water circulating through the coil 5 with the help of the pump 7. Water is heated in the coil 5 through the pipe 6 and the internal channel of the rotary coupling 8 enters the coil 9 of the heat exchanger 10, where the heat of the water is transferred to another liquid (technological solution, network water for heating, etc.). Cooled in the coil 9, the water through the pump 7 and the outer channel of the coupling 8 flows back into the coil 5.

The disassembly of the swivel coupling 8 by an open drain 2 and the discharge head 3., is by disconnecting the flange connector. On the inner surface of the drum 1, 14, disassembling the stuffing box connector 15, pouring the pouring flanges 4, and shifting the outer part 23 to the branch pipe, The outer surface is a coil 5, which is supplied with water from the pump 7. From the semi-tubes welded to both-Shift of the part 23 opens access to the drum opening. Coil 5 with the help of a pipe gland connector 15 on the internal pipelines 6, the pump 7 and the two-channel 20 pipe 12.

The swivel coupling 8 is connected to the serpent. The assembly of the coupling 8 is carried out in a return 9, placed in the heat exchanger 10, into a single closed circulation circuit. The latter has a feed 11 to compensate for the loss of water through the stuffing box 25, using inserts 18 with a seal hole in the pump 7 and a swivel coupling 8 19 in them for the passage of water. The seal assembly of the coupling half 8 is performed with

The two-channel swivel coupling 8 using gland rings 21 and the gasket is made in the form of two tubes 12 and 13 of one different diameter placed with one another

n order.

Alignment of inner pipes 12 with respect to outer pipes 13 of implementation 22.

To reduce heat loss by the flange connector 14 on the outer tube 30 by cutting the surface of the drum 1 and coil 5

13 and the gland connectors 15 and 16 on the pipes 12 and 13, respectively. A sliding thrust bearing 17 is provided to compensate for the thrust collar 7 of the axial force. For precise centering of the pipes 12

closed with a layer of thermal insulation (not shown).

The invention allows maximum use of the heat of heated water in an external stationary heat exchanger and more

In tubes 13, inserts 18 with a hole - 35 serve; reliably cool this water for repeated 19 in them, bringing water into the drum 1. The axial arching force of the inner tubes 12 is compensated by end bottoms 20 on the outer tubes 13. The tightness of the coupling 8 is provided by rings 21 stuffing box and gasket 22.

The device works as follows.

The red-hot material (for example, sinter) flows into the drum 1 through the chute 1. Due to the slope and rotation of the drum 1 of the efficiency of the refrigerator, it is equipped with a rival moving in the direction of discharge placed outside the heat-sink refrigerator than in the coil located inside the drum.
