Abstract
A b s t r a c t A device for closing the charging hole of a container resistant to pressure comprises a lid pivoted such as to permit swiveling inwards and a drive assembly linked to the outside of the con-trainer which drive assembly is connected with the lid by a traction element turned round over a roller arranged above the charging hole . Outside the container a charging chute closed on all sides is connected with the edge of the charging hole.
Description
~2~gS~
The invention relates to a device for closing a charging hole of con-trainers resistant to pressure, particularly autoclaves, comprising a lid which can be lowered inwards into the container and the outer diameter of which lid exceeds the inside diameter of the charging hole, and a drive assembly which is supported against the outside of the container for opening and closing the lid, wherein a charging chute closed on all sides is supported against, particularly connected with the edge of the charging hole. Favorably the lid is arranged such as to be lowered inwards into the container for opening, because by this means the internal pressure of the container and/or the auto-crave supports tight closing of the lid. Such a device in which the lid is opened into the interior of the autoclave is Icnown from the DEMOS 3 241 784. In this well known embodiment the lid is connected by a rod with a drive assembly formed by a hydraulic piston-cylinder unit. This rod must be guided through the chute and the lid is guided by this rod only when being opened or closed. The lid is subjected to great strain, as the material in pellets supplied by the chute drops onto the lid when it is opened, and such a guidance by means of a rod is therefore greatly strained, susceptible to damage and expensive. Except for that the lowered lid obstructs the supply of the material in pellets and/or the coal to the autoclave and the space of time required for filling the autoclave increases.
.
The present invention provides a sturdy and safe device for opera-tin the lid and to reduce the time required far filling the con-trainer. The invention consist. herein essentially in the lid go , \
. . I, .

being pivoted to the edge of the charge hole such as to permit swivel-in inwards, in the drive assembly being supported against the outside of the container itself and being connected with the lid by at least one traction element and a deflection device for the traction element being supported against the charging chute above the charging hole.
By the lid being pivoted to the edge of the charging hole and not being guided by a rod which allows vertical lowering, the charging hole is completely cleared when the lid is open. Thus a shorter stretch of time for supplying the container with material in pellets is no-squired. Such an autoclave is particularly suitable for a process for drying coal a~r~iing--t~ leisEner. In such a process the coal to be dried is fed to the autoclave and subsequently charged with super-heated and/or saturated steam under pressure. By reducing the time of filling the stretch of time required for carrying out the whole process is reduced. Good guidance of the lid in opening and closing is also achieved. When the lid is guided by a rod as it is in the known embodiment there is the risk of the rod being damaged or deformed by the material filled, by which means safe closing of the lid is impaired. By the lid being closed and opened by means of a traction element this risk of an impairment of the safe guidance of the lid is cleared up. The guidance of a rod at the charging chute above the filling hole is not accurate. By the fact that only one deflection device for the traction element is supported against the charging chute and that the operation of the lid is effected by the traction element in the embodiment according to the invention, inaccuracies which can occur by the support against the charging chute do not affect the function of the lid. higher filling level of the autoclave is ~22~S~
also made possible, as the lowered lid dips only by a peripheral zone into the material filled.
According to the invention the lid is pivoted with clearance in direct-ion vertically to the plain of the edge of the charging hole. This can be simply effected by the pivot axis of the lid being guided in oblong holes extending vertically to the plain of the edge of the charging hole. Owing to this clearance the lid can be lifted vertically by the traction element in the last closing stage and be pressed evenly with its whole circumference against the sealing edge of the charging hole. According to the invention the lid comprises suitably a support-in bracket protruding upwards to which the traction element holds at a distance of the plain of the lid and axially towards the lid.
In this way centering of the lid when being attached to the sealing edge of the charging hole is facilitated. Herein particularly the upper side of the lid is covered by a pyramid- or cone-shaped casing, wherein the traction element holds to the top of the pyramid or the cone of the casing. By this casing piling up of the loose material and/or the coal on the lid is avoided. The lid is of a heavy weight.
For achieving greater stability the supporting bracket can be formed according to the invention by essentially triangular metal sheets arranged radially and vertically to the lid which are optionally covered by pyramid- or cone-shaped casing faces.
In a preferred embodiment of the invention the arrangement is effected so that the edge of the charging hole and the lid have cone-shaped ~Z~6~
contact surfaces and a ring conduit comprising outlet nozzles which is intersected by the generators of the cone-shaped surface of the edge of the charging hole is arranged below the edge of the charging hole. Through these outlet nozzles steam or compressed air is exhausted in the last stage of closing the lid and, as this ring conduit is intersected by the generators of the cone-shaped surface, the jets run through the gap between the lid and the edge of the charging hole and clean this gap, so that tight closing is ensured.
according to the invention the charging chute which is located between a stop valve separating a charging bunker and the autoclave is detach-able, particularly slid able laterally over slide bars fixed to the valve frame. The dead weight of the charging chute can be lifted up by an auxiliary lifting device and thus the charging chute can be moved laterally without expenditure. By detaching this constituent the lid, the edge of the charging hole and also the stop valve become accessible for cleaning and repair work according to the invention the drive assembly is suitably formed by a hydraulic piston-cylinder unit, the traction element is formed by a chain or a rope and the deflection device by a roller.
The invention is explained schematically with reference to the accompanying drawings, in which:-Fig. 1 is a vertical section through an autoclave with the charging . lo chute, Fig. 2 is a top view onto an embodiment of the lid and Fig. 3 shows the pivot joint of the lid to the edge of the ehargin~ hole of the autoclave.
The autoclave 1 has at its upper side a charging hole 2 which is shut off by a lid 3. The lid is swivel-~ounted to a rim or dye 4 of the charging hole by means of a pivot 5 and can be opened downwards into the posit-on 3' marked b-y a broken line. 6 is a reinforcement welded to the side 9 of the autoclave l to which reinforcement the edge 4 of the charging hole 2 is screwed on.
