Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] The chain-type automatic flow regulator shown in the figure includes an air inlet pipe 7, and an outer pipe 1 is arranged on the upper periphery of the air inlet pipe 7.

[0013] A plurality of adjustable air inlets 3 are opened along the axis on the side wall of the air inlet pipe. The follow-up parts include an inner cylinder 4 and a plurality of chains 5 . The periphery of the inner cylinder is in sliding contact with the inner wall of the air inlet pipe, and the inner cylinder is slidably connected with the air inlet pipe up and down in the axial direction of all adjustable air inlets within the axial length range of the air inlet pipe. When the inner cylinder slides up and down, the side wall of the inner cylinder can block the adjustable air inlet 3 at the part radially opposite to the side wall of the inner cylinder. W...

Abstract

The technical problem to be solved by the invention is as follows: the existing cement clinker cooling machine can not automatically adjust the cooling air. The invention provides an automatic flow regulator which can adjust the input air according to the magnitude of material layer resistance. The chain-typed automatic flow regulator comprises an air inlet pipe provided with an adjustable inlet opening, and a follow-up unit which moves along with the increase of the pressure difference between the interior and exterior of the air inlet pipe to lead the ventilated area of the adjustable inlet opening to gradually decrease.

Description

technical field [0001] The invention is an automatic regulator for cooling air flow applied to a cooling machine. technical background [0002] The cooling machine is a very important equipment in cement production, which undertakes the tasks of cooling, conveying and heat recovery of cement clinker. The main function in the cement process is to cool the high-temperature clinker discharged from the rotary kiln to the temperature that the downstream conveyor, storage and cement mill can withstand, and at the same time recover the sensible heat of the high-temperature clinker into the firing system as The secondary, tertiary air and drying air of the kiln improve the thermal efficiency of the entire firing system. The cooler uses air as the medium to pass through the high-temperature clinker to cool the clinker, and at the same time recover the heat of the exhaust gas to improve the thermal efficiency of the kiln. The cooling rate of clinker has a great influence on the stru...
