Problems solved by technology

[0008] In EP0848646 the pressure loss in the unit will become high because now the orifice area in the unit is smaller and the fan supplying the cooling air has to overcome this pressure loss
In practice, the fan design would be oversized if it could handle the above operations

Embodiment Construction

[0032] figure 1A cooler 1 is shown comprising an inlet port 2 and an outlet port 3 . The cooler is connected to the rotary kiln 4 from which the cooler receives the hot material to be cooled. The material coming from the rotary kiln 4 falls on the distribution bottom 5 arranged in the cooler 1 and the material is conveyed as a material layer 6 on the distribution bottom 5 from the inlet port 2 to the outlet by means of transport means (not shown) End 3. The transport device may be, but is not limited to, a reciprocating grate, a reciprocating pole, or a ground running device. The cooler 1 comprises one or more compartments 7 below the distribution bottom 5 , wherein each compartment is supplied with cooling air from a fan arrangement 8 . The compartment 7 may be divided into a plurality of smaller compartments (not shown) longitudinally and transversely of the cooling machine 1, and if so divided, cooling air is supplied to each individual compartment. The distribution bot...

Abstract

Device for use in a bottom construction of a bed for cooling particulate material, where said device comprises a frame comprising means for fastening said device to the bottom construction, and where inside the frame a primary and a secondary opening is provided, where said primary and secondary openings allows cooling air to pass through the frame and thereby through the bottom and through the bed of particulate material, and where a pendulum plate is pivotably arranged on an axle, such that the pendulum plate may pivot and thereby block off more or less of the primary opening, and where said pendulum plate is biased towards a position allowing the primary opening to be as open as possible.

Description

technical field [0001] The invention relates to a method for cooling with air a bed of granular material supported on an air distribution bottom, wherein the air is guided in a sectionalised manner from one or several compartments located below to the air via ducts The distribution bottom and the bed of granular material are passed upwardly through both while the granular material is conveyed either horizontally or slightly inclined from the inlet end of the air distribution bottom to the outlet end of the air distribution bottom. [0002] The invention also relates to a device and a device for carrying out the method according to the invention. Background technique [0003] An example of a device comprising an air distribution bottom is a cooler for cooling, eg for cooling cement clinker. In such coolers, the main objective is to achieve a satisfactory degree of heat exchange between the clinker and the cooling air so that substantially all of the thermal energy contained ...
