ROTARY COOLER FOR CEMENT CLINKER, ETC.
Application led .Tune 7,
To LIZ whom 'it may concern.'
Be it known that l, Fovr. T. LINDHARD, a citizen of the United States, residing in thev borough of Brooklyn, of the city of New York, in the State of New York, have invented certain new and useful lmprovements in Rotary Coolers for Cement Clinker, Etc.,
of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.
This invention relates to rotary coolers of the general type of that shown in Letters Patent of the 'United States No. 1,049,610, dated January 7, 1913, and No. 1,503,193, dated July 29, 1924. The object of the present invention has been not only to improve the construction in some particulars but to simplify and reduce the cost of construction of such coolers, particularly when the cooling requirements are not severe, as when the room in which the cooler is placed is well ventilated and the heat radiated from the shell of the cooler is readily disposed of. rlhe invention is particularly concerned with the introduction of the cooling air, the construction and arrangement of the air seals, the suppression of dust, etc., and will be eX- plained more particularly hereinafter with reference to the accompanying drawings in which it is illustrated and in which- Figure 1 is a view in longitudinal section,
vpartly diagrammatic, of a cooler in which the improvements are embodied.
Figure 2 is a view in transverse section on the plane indicated by the broken line 2 2 Df Figure 1.
Figure 3 is a detail view in section and on a larger scale showing particularly the construction and arrangement of ,the air seals at the feed end of the cooler.
'i Figures 4 and 5 are detail views in section on the planes indicated by the broken lines 4-4 and 5.-5, respectively, of Figure 3.A
Figure 6 is a detail view in section, also on a larger scale, showing particularly the construction of the air seal at the discharge end of the cooler.
, In the embodiment of the invention illustrated the outer or main shell'a is shown as cylindrical and as supported as usual by riding rings or tires a which rest on rollers ya?, movement of rotation being imparted to the shell in any suitable manner. Within the main shell, separated therefrom by an annular space and extended from the feed 1924. Serial No. 718,456.
f end of the cooler for a portion only of its length, is an inner shell b, which is open at both ends, its left hand end having a conical flange, as at b', to prevent the spilling of the clinker into the dust chamber e. rl`he annular space between the two shells is closed at the left hand end, as by a Hange b2, but is open at thel right hand end so as to permit the free passage of air from the annular space within the shell b at a point relatively near the feed end of the cooler'. This cooling air, which first comes in contact with the shell b and then with the incoming clinker where the temperature is highest, is received under pressure from any suitable source, such as a fan d, being conducted through a conduit al to an air pressure chamber d3 formed between air seals Z4 and d supported in the wall of the dust chamber', the cooling air passing from the chamber, d? to the annular space between the two shells through openings d formed in the main shell a. The coolingair, after it hasperformed its function, passes, as usual, through the open end of the inner shell b into the dust chamber e from which it escapes after the dust has been deposited. 'lhe hot clinker or other material to be cooled is delivered from the kiln or other source through a chute f and the open end of the inner shell b into the space within the shell and then travels, as usual, to the discharge end of the cooler.
Near its discharge end the main shell a may be formed with holes to permit the smaller clinker to be discharged and is provided at its end with an inturned angle a4 to impede the passage of the smaller'clinker, while permitting the larger pieces of clinker to pass from the shell. rlhe discharge end of the shell is enclosed within4 a hood h which has at k an inlet for cooling air under pressure from any source and at 72.2 an air seal. The hood has also a partition ha which fits rather closely to the shell at its under side, preferably for about a third of its circumference, as shown at h4 in Figure 2, but through the remainder of the circumference is separated therefrom by a partly annular space as at k to permit the free passage of air from the air chamber he intothe chamber k7 of the hood, this air passage h being formed by a conical flange 72.8 to direct the passage of air into the air
