Description

The present invention relates to equipment

  coking plants and, more specifically,

  includes a device for diverting, receiving and transferring the incandescent coke from the coking chamber to the coke extinguishing station.

  The invention is most successfully applicable in combination with

  with dry extinguishing processes.

  Devices are known for receiving and transferring the incandescent coke, of the type comprising a removable receiving C box, open at the top, and

  a trolley for the transport of this box. In operation

  However, these devices have the drawbacks of causing: - firstly, a free release of gases and dust from the coke, which, due to the fact that

  it is transferred to the lift of the installation

  Drying out in open crate leads to the pollution of the atmosphere, and secondly, a loss of coke in high coke, 2C resulting from the intense combustion of it in the

  open top of the box. On the other hand,

  that the loading of the known devices by the

  coke ducts fitted with a ventilation hood.

  flue gas, there is a problem relating to the creation of a vacuum in the hood for the suction of

smoke and gas.

  There is also a device for

  the receipt and transfer of the incandescent coke (see USSR author's certificate No.467086), which 3C device includes an anti-fume hood mounted at the coke-removal station, a receiver box of the cottle irunie d ' a neck tapering upwards, which ends with a loading opening, and a carriage carrying the coke receiving box and serving for the transfer of coke

  incandescent from the diversion post to the extinguishing station.

  Although the device under consideration has a smaller loading aperture than that of the devices described above, it is ensured, just as in the previous case, that there are gussets and gases in the atmosphere and at the same time. e: e-te, u high coke fire, which is due to the fact

  to transport the coke in an open crate.

  The invention therefore aims to develop a

  in coke when transferred to the receiving box.

  The problem is solved by means of a

  for diversion, reception and transfer

  incandescent coke, of the type comprising an anti-fog hood

  : umée installed at the coke turning station, a coke receiving box with a retracting neck

  In the case of this box, below the bottom of the box, it is antiluned and animates said lid so that it rolls along the surface of its pebbles by means of its pebbles. inclined director of the arms. When removing the lid, when the box is taking its position below the smoke hood to be loaded with coke, the other projection of the box comes into contact with the projection of the lid and, while pushing it, makes move the lid whose pebbles roll on

the leading surfaces of the arms.

  Designed in this way, the device allows the transfer of incandescent coke from the diversion station to the extinguishing station without the occurrence of release of gases and fumes into the atmosphere and, consequently, of

  From the moment when the coke is diverted, no more gas and smoke are evaded, which is due to the fact that these gases and fumes are evacuated from the hood by suction, when the coke is being removed, and that the loading opening is closed as soon as the loading operation is completed and the receiving box starts to move from below the smoke hood, the latter advantage being possible thanks to the new design of the device. Since the device according to the invention is supposed to operate at high temperatures, the problem has been solved by simple means which, in operation, do not require any manpower, controls or organs. analogues which, given these conditions

  would be very complicated to perform and unreliable.

  According to one of the embodiments, the directional surfaces of the arms have recesses for the rollers, used for fixing the lid in the raised position, the projection cooperating with the projection of the lid during the removal of the latter having a surface double slope and the protrusion of the lid comprising a

  roller adapted to roll on this double slope surface.

  This design of the device contributes to improving the reliability of the entire device and, in particular, contributes to the fixing of the cover on the arms and makes it easier for the rollers of said lid to come out of the depressions in question when the closure is closed. loading opening and thereby guarantee the

  smokeless transfer of the incandescent coke.

  Another embodiment of the device according to the invention is characterized in that the lid is provided with a frame of circular section while the loading opening is framed by an upper chord having inner and outer surfaces. disposed at an angle to each other and to the plane of the loading opening so that

  closing position the lid frame comes into con-

  tact with the outer surface of the upper chord.

  This design of the entire lid makes it possible to prevent the incandescent coke from sticking to the combined surfaces of the receiving box and the lid, and to obtain the essential seal between the lid.

  and the walls of the box, including its upper chord.

  To protect the upper chord against

  the effect of high temperatures and thereby guarantee the

  the integrity of the assembly-top-chord, it is advantageous to provide it with a lagging heat shield

  pool. The invention will be better understood and other purposes, details and advantages thereof will become more apparent to the

  light of the following explanatory description of a

  presently preferred embodiment with reference to the accompanying non-limiting drawings in which:

  FIG. 1 is a schematic view of a device

  sitif according to the invention receiving incandescent coke;

  FIG. 2 is a schematic view of the arrangement

  sift according to the invention during the transfer of coke into the box or during transport thereof for the purpose of loading - Figures 3 and 4 are top views of the devices of Figures 1 and 2, respectively; FIG. 5 is an enlarged sectional view of the assembly of the lid on the caesotrophicocoke. As can be seen in FIG. 1, the device -Folur the defournemert, the reception and the transfer of the incandescent coke comprises a smoke hood I mounted at the coke diverting station, below the school duct of a coke machine. removal of pràs (not shown), which hood is connected to a system for evacuation of fumes and gases, a box 2 receiving the coke with a neck 3 tapering upwards which ends with a loading opening 4 and a carriage C carrying the. receiving box 2 and used to transfer the incandescent coke

  from the diversion post to the extinguishing station.

  As can be seen from FIGS. 1-4, where the device according to the invention is represented during the loading operation and in the operating position, four arms 6 are attached to the smoke hood 1, their number being reduced to two. without impairing the effectiveness of the device according to the present invention. The arms 6 are, in this case, substantially parallel to each other and arranged in the same horizontal plane. The two middle arms are equal and longer than the extreme arms, which are also the same length. To increase the carrying power of the arms C,

  these are further connected to hood 1 by means of

  stiffener 7. Each of the arms 6 has a

  directing surface 6 inclined towards the free end ú.

  The device according to the invention also comprises a cover 10 serving to close the loading aperture

  3 4 as soon as the receiving box 2 is filled with coke

  descent. The lid 1C is provided with suitable rollers 11

  rolling on the leading surfaces 8 and connected to that cou-

  circle with projections. In this case, the cover 16 is provided with four rollers 11, their number corresponding to the number of arms 6, among which there are two front rollers and two rear rollers. The front rollers are intended for driving on the extreme short arms and the rear frets on the long middle arms. As shown, the rollers are arranged so as to dominate the cover 1 or over it, which however does not mean that said cover can not be in the same plane as them or dominate them . In the embodiment of the invention, the cover 10 is in the position closest to the loading opening, that is to say that the travel of the cover between the closing position and the opening position is, in this position

the shortest.

  The lid 10 is provided with a projection 12 which, in the embodiment under consideration, is oriented towards

  down and whose function will be specified in the develop-

subsequent payments.

  On the other hand, the guide surfaces 8 have recesses 13 for the rollers 11, in this case, for the front rollers. The troughs 13 allow the fixation of the

  lid 10 in the open position.

  As shown in the drawings, the receiving box 2C 2 comprises two projections 14 and 15 which are made externally on the lateral part or on the neck 3 of said box so that in operation they cooperate in turn with the projection 12 In the illustrated embodiment, the projections 14I and 15 are 2, arranged substantially in the same horizontal plane and are spaced apart so that in operation they can not prevent the evolutions of the projection 12, the projection 15 having a surface to double slope for acting on the projection 12. To reduce the friction of the projection 12 3C against the surface of the projection 15, the first is provided

  a roller 16 adapted for rolling on this surface.

  As can be seen from FIGS. 1 and 2, the slopes of the surface that the projection 15

  in the direction of movement of the body 3 for the charge-

  and Neutral 'sns e sense of displacement of this box

tackle the loading.

  It should be noted that the projections 14 and 15 can be made on either side of the neck 3 as well as a projection similar to the projection 12 can be

  made on the opposite side of the lid 10.

  In FIG. 5, a cut made at the location of the assembly of the lid 10 at the neck 3 is shown in enlarged scale. According to the invention, the lid is provided with a frame 17 of circular section, while

  the loading opening is framed by a higher chord

  18. The upper chord 18 is of box section and has outer-19 and inner surfaces which are arranged to form an angle with each other and both with the plane of the opening of the

  loading 4, which is normally a horizontal plane.

  The upper chord 18 and the frame 17 are arranged so that, with the lid in the closed position, the frame 17 is in contact with the surface

  outside 19 of the upper chord 18.

  The inner surface 20 of the frame in question is protected by means of a heat-insulating screen 21 which serves at the same time for fastening panels of

coating 22.

  In operation, the receiving box 2 is

  installed, to be charged, below the anti-fog hood.

  smoke 1 so as to be separated from this hood of -

  the minimum space a (Figure 1). Meanwhile, the cover 10 is on the leading surfaces 8 of the

  arm 6, its rollers 11 being depressed, in the example considered

dere, in the hollows 13.

  As soon as the receiving box 2 is filled with incandescent coke, it is moved towards the location where the cover 10 is located, one side of which rises in part because the roller 16 strikes the slope of the protrusion

  and follows it going up under the effect of the protrusion 14.

  The unilateral rise of the lid results in the rollers 11 coming out of the recesses and the cover 10 rolling,

  on its rollers 11, descending on the surfaces

  8. Meanwhile, the projection 12 is between the projections 14 and 15 because the receiving box continues its movement away from the smoke hood 1 and the slope of the leading surface 8 and finally, the slope and the rolling path of the roller 16 on the portion of the surface that has the projection 15 on the side of the projection 14 are chosen so that the roller 16 can not exceed the apex b of said projection 15. This is how the control of the speed and the stroke of the lid 10 is exerted.

  when placed on the loading opening 4.

  With the lid 10 in place, the receiving box 2 continues its path towards the extinguishing station of the incandescent coke. The receiving box 2 being unloaded by its lower opening (not shown), it is done

  move, with the lid 10, to the emptying station

coke.

  When the receiving box 2 is taking its position below the smoke hood 1, the cover 10 collides with the arms 6 and the rollers 11 start to roll on the guide surfaces 8 while raising the cover 10 under the effect of the projection which acts on the projection 12. The respective rollers 11 having arrived and driven to the recesses 13, the roller 16 exceeds the vertex b of the projection 15 and the receiving box 2, already open, continues its way to take the position
