Abstract

The invention relates to a technique for cooling kilned materials and can be used in the manufacture of building materials. The purpose of the invention is to increase the cooling efficiency. The grate cooler contains a series of moving and fixed air-permeable grates with forward pushing ledges. For grates located closer to the longitudinal axis of the refrigerator, the height of the front pushing ledges is greatest, and the height of these ledges can be made adjustable, and their height in longitudinal rows will decrease as the material progresses. The material from the furnace falls on the grate 4 with the height of the step T, which pushes it along the axis while simultaneously creeping to the right and left, which ensures a more even distribution of the material over the grate and increases the cooling efficiency of the material. 1 hp f-ly, 3 ill.

Description

one

This invention relates to a technique for cooling kilned materials and can be used in the building materials industry.

The aim of the invention is to increase the cooling efficiency.

Figure 1 shows the refrigerator, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - the grate with adjustable ledge height.

The rotary kiln 1 enters the shaft 2 of the refrigerator 3 with a grate, consisting of a series of moving and stationary breathable grates 4 and 5 with the height of the front pushing ledges T,.

The height of the ledges T of the average longitudinal moving and stationary grates is taken to be maximum and is determined depending on the productivity of the furnace with regard to transporting capacity (the greater the height of the ledge T and the greater the number of moves back and forth of the grid bars, the greater the transporting capacity).

The height of the pushing ledges T of adjacent lengths of rows is taken (0.9-0.2) T, depending on the size of the average grain size of the material and the width of the grate (the larger the granule and the wider the grid, the greater the height of the ledge T2), followed by models.

The height of the ledges T, T, etc. depending on the height of the next higher row, according to a similar relationship.

With a small width of the grate, only one or two longitudinal rows of grates can be installed in the middle part with the heights of the ledges T, and all the rest with the heights of the protrusions T (this is also established by the commissioning experiments).

In order to enable and simplify the adjustment work, the grates of the grate cooler can be made with an adjustable height of the front step T (Fig. 3).

6, connected in one piece by a wall 7 and a corner of 8.

In the walls 6 there are holes in which, with their trunnions 9, the grate IO enters with slots 11 and front ledge 12. A gasket 3 can be installed between the ledge, 12 and the corner 8, and bolted

ten . If the gasket 13 is of the maximum design value, then the height of the front ledge is equal to T, if the gasket 13 is completely removed, then the plate 10 rests into corner 8 and becomes equal to

15 calculated.

The remaining dimensions of the grate are determined constructively and tested for strength.

The refrigerator works as follows.

The material from the furnace 1 falls on the middle grate 4 with the height of the ledge T and it is quickly pushed along the axis while moving to the right

25 and left. This prevents the formation of a thick layer of material in the middle part, which ensures a more even distribution of the material over the lattice.

30 The use of grates with an adjustable step height T facilitates and improves the setting up of the refrigerator.

The use of this refrigerator will ensure greater efficiency
