CARBONIZING RETORT FOR USE IN COKE AND GAS PRODUCING CHAMBER OVENS Filed May 14, 1955 Patented Aug. 10, 1937 PATENT orrics CARBONIZING RETORT FOR. USE'IN COKE AND GAS PRODUCING CHAMBER OVENS Carl Still, Recklinghausen, Germany Application May 14, 1935, Serial No. 21,471 In Germany May16, 1934 g 4 Claims. (Cl. 202-217) Therinvention is concerned with the problem of producing low or medium temperature coke in existing coke and gas producing chamber ovens by means of suitable iron carbonizing retorts arranged in the chamber oven.
The insertion of iron carbonizing retorts into chamber ovens for producing coke and gas is in itself already known. The improvement according to the invention consists in that a vertical iron retort shaped to correspond approximately with the: shape of the chamber and arranged to discharge downwardly, is suspended freely from the arch of the chamber. The retort is charged through the existing charging holes of the chamber. oven and the charge can then be levelled in the usual manner. The coke is removed at the bottom part of the chamber oven and for this purpose a hinged cover plate on the vertical retort is located a certain distance above the bottom of the chamber oven. The low temperature coke removed from the chamber ovens is after discharge from the retort pressed out of the chamber by means of the usual pusher bar of the coke pushing machine with the use of aux- 5 iliary devices to be hereinafter described.
The form of construction of the carbonizing retort according to the'invention will now be described in detail by reference to the example of construction illustrated in Figs. 1-3 of the drawing.
Fig. 1 is a vertical cross-section of the oven along the line l! of Fig. 2 and on an enlarged scale as compared with Fig. 2. Fig. 2 is a longltudinal section on a reduced scale through half of a horizontal chamber oven (coke side). Fig. 3 shows a detail of Fig. 1 on an enlarged scale illustrating a side elevation of a portion of the retort with its closure member and the locking devices therefor.
Referring to the drawing, l denotes the oven chamber of a coke and gas producing horizontal chamber oven which is heated in known manner by heating fiues on both sides of the chamber such as that indicated at 2 and is charged from the top'through charging holes Id.
In the construction according to the invention, in these existing horizontal chamber ovens which are combined to form a battery, there are freely suspended from the chamber arch one or more vertical retorts 3 which are arranged to empty downwards. With this object in view, the vertical retort 3 which widens downwards in conical fashion and whose upper end is widened so as to form a continuous gas collecting chamber 4,
is attached to iron supports 5 which are interconnected. by webs 6 to form a rigid supporting member; By means of screw bolts 1, which pass through the cover of the chamber and are fixed to the webs 6, the vertical retort 3 is secured under the cover arch of the oven chamber 1. The width 5 of the vertical retorts measured in the direction I of the width of the oven chamber, preferably amounts to only a fraction of the usual chamber width of horizontal chamber ovens, for example approximately -120 mm. In order that each 10 freely suspended retort may be prevented from swinging, it is stayed against the walls of the chamber by bolts 8. The height of the vertical retorts likewise amounts to only a part, approximately two-thirds, of the height of the existing 15 oven. chambers, in order to allow room at the bottom for discharging the low temperature coke from the retort into the oven chamber I. A flaplike hinged cover plate or closure member 9 of the vertical retort 3 is held by two claw-shaped 20 locking devices l0 and H which are adapted to be turned outwards by means of shafts I2 and I3. The opening is efiected in such manner that first of all the claw l I is, by means passing through one or both oven doors, moved from under the 25 hinged cover plate 9 by turning the shaft l3, and then the plate 9 is swung down by the arm l0 fixed i thereto being turned. The coke falls on to a metal plate I6 which rests on the bottom of the oven during the carbonization process or is in- 30 serted shortly before discharge from the retort, which plate, together with side walls l1, preferably provided thereon, forms an open box or trough, in order to facilitate the removal of the coke from the chamber. The metal plate It is 35 thrust out by means of the pusher bar !9 (indicated by broken lines in Fig. 1) of the coke pushing machine. The trough consisting of the base plate I6 and the side walls H can be subdivided into separate boxes by transverse walls l8 (Fig. 0 2), in order to prevent the coke from becoming congested and thereby possibly pulverized, while the base plate I 6 is being pressed out.
After the coal has been inserted into the retorts 3 through the charging holes l4, it is levelled in 45 the usual manner by the levelling bar I5 (Fig. 1) of the pushing machine, which, its width being suitably modified, is moved inside the funnelshaped gas collecting space 4 of the vertical retort 3.
In order to obtain greater stiffening of the freely suspended walls of the vertical retort 3, and particularly in order to prevent them from being twisted by being heated to the desired temperature for carbonization (about 500) or for 55 in order to facilitate the levelling of the coal and also the removal of the Volatile carbonization products. The distillation gases leave the retorts through the ascension pipe of the horizon- 15 tal chamber oven.
What I claim is:-
1. In an externally heated horizontal coking chamber oven having a roof with the usual unobstructed charging openings therein, a carboniz- 20 ing retort arranged wholly within said chamber oven and suspended from the roof thereof at points intermediate said charging openings, means for charging said retort through said charging openings, and means for discharging the 25 contents of. said retort within the chamber oven. 2. In an externally heated horizontal coking chamber oven having a roof with the usual unobstructed charging openings therein, a carbonizing retort arranged wholly within said chamber Q oven and freely suspended from the roof thereof at points intermediate said charging openings, means attached to said retort and engaging the walls of said chamber oven for preventing swinging movement of said retort, the horizontal sides 3 of said retort at the top thereof diverging outwardly to form a funnel, means for charging the funnel end of the retort through the charging openings in the chamber oven roof, and means for discharging the contents of said retort within the chamber oven.
3. In an externally heated horizontal coking chamber oven having a roof with charging openings therein, a carbonizing retort arranged wholly within said chamber oven and suspended from the roof thereof, said retort being frusto-conical in cross section for maintaining the material to ,be coked in a solid frusto-conical shape within said retort for easy delivery to said chamber oven and the sides of said retort at the top thereof diverging outwardly to form a funnel-shaped portion, means for charging the funnel end of the retort through the charging openings in the chamber oven roof to deliver material to said retort, and means for discharging the contents of said retort within the chamber oven. 4. In an externally heated horizontal coking chamber oven having a roof with the usual unobstructed'charging openings therein, a carbonizing retort arranged wholly within said chamber oven and suspended from the roof thereof at points intermediate said charging penings,-said retort having a discharge opening, means for charging said retort through said charging openings, a closure for the discharge opening of said retort comprising a cover plate fixed to a spindle pivotally carried by the retort and extending outwardly through the oven end structure, and means on the spindle outside of said oven structure for operating said spindle to open and close the cover plate.
