Definitions

  • the present invention relates to a device for cleaning the dormant frames of a coke oven door.
  • This tool holder frame is movable relative to a fixed frame which can be moved away, brought closer and adjusted in position relative to the door frame to be cleaned.
  • This fixed frame also carries a lower squeegee, which has the function of ensuring the scraping of the bottom of the oven and of the lower part of the door frame. With this squeegee, when approaching the cleaner, the large pieces of coke are pushed back into the oven while the smaller parts are removed when the cleaner recedes to its inactive position.
  • the distance, the approximation and the adjustment in position of the cleaner are generally carried out by means of a translation beam to which the fixed frame is coupled by means of a ball joint, and by a jack coupled between the fixed frame and a structure linked to the beam.
  • the invention intends to remedy these drawbacks by means of a device for cleaning coke oven door frames in which at least some of the cleaning tools are driven by a combined rectilinear-reciprocating and rotary movement.
  • the subject of the invention is a device for cleaning the facade and interior surfaces of a coke oven door frame comprising a first frame capable of being brought closer, distant and adjusted in position relative to the door frame to clean, a second frame located in front of the first frame and movable vertically with respect to the latter, guide means being provided between the first and second frames as well as motor means capable of alternately generating the above-mentioned vertical movement, the second frame constituting the support for a plurality of tools for scraping the door frame.
  • the door frame scraping tools further include a plurality of scraping blades fixed to the second frame on the front face of the latter by means of elastic fixing blocks, so as to protrude laterally and in front of the action plane. burs, to be brought into contact with the interior surfaces of the door frame. As the interior surfaces are in clearance relative to the plane of the front surfaces of the door frame, the active edges of the scraper blades are contained in two vertical planes converging towards the front of the second frame, said blades being interposed between the side cutters of this second frame.
  • each cutter is mounted in its bearing against an elastically deformable element in the axial direction.
  • the mechanism for connecting the carriage to the second frame comprises an oscillating lever articulated by one of its ends to the first frame, its second end being coupled to the carriage by a sliding connection in the vertical direction, this lever being connected between its two ends to a drive finger integral eccentrically with a toothed wheel rotatably mounted about an axis carried by the second frame, perpendicular to its plane of movement, said cooperating wheel with a rack integral with the first fixed frame.
  • FIG. 1 a frame C of the coke oven door.
  • This frame has two vertical uprights 1 and 2, a lintel 3, and a threshold 4.
  • Each of these parts has a facade surface 1a, 2a, 3a, 4a, and an interior surface 1b, 2b, 3b, 4b. These are the surfaces that need to be cleaned as quickly as possible.
  • the device according to the invention shown in Figure 2 comprises a first frame 11, called a fixed frame, and a second frame 12, movable vertically relative to the frame 11, in an alternating movement indicated by the double arrow A.
  • the device Under the frame mobile 12, the device comprises a carriage 13, the movement of which relative to the frame 11 is indicated by the double arrow B.
  • a support structure for the cleaner the invention which essentially comprises a translation beam 14a, and a rear base 14b, between which and the frame 11 is coupled a jack 15.
  • FIG. 3 schematically represents the connections between the structure 14, the beam 14a of which is capable of rolling on a guide track 16, and which is equipped at its end with a ball joint 17 to which the fixed frame 11 is suspended.
  • the frame 11 comprises guide members 18 for the frame 12.
  • a possible embodiment of these guide members comprises, carried by the frame 11, rollers 19 and rollers, orthogonal, which form a prismatic connection between the two frames, allowing only the relative movement along the double arrow A.
  • the cylinder 15 which adjusts the verticality of the assembly of the two frames, and their parallelism with the frame they must approach.
  • a jack 21 is coupled between the frames 11 and 12 to generate the above-mentioned vertical reciprocating movement.
  • the frame 12 is equipped with bearings 22 regularly distributed along each of its vertical lateral edges. These bearings support cutters 23 which have a cutting face 23a. When placing the cleaner against the frame to be stripped, the cutting faces of the cutters are applied against the external surfaces 1a and 2a of the uprights of the frame C. Beyond this bearing, the cutters are secured to a tail 24, which carries a pinion 25 meshing with a rack 26 carried by the corresponding edge of the fixed frame 11. It is understood that the vertical reciprocating movement of the frame 12 on the frame 11 generates an alternating rectilinear movement of the strawberries 23 and , by the engagement of the pinions 25 on the corresponding rack 26, an alternative rotational movement of the cutters in their bearing 22. The efficiency of the pickling tools is notably increased.
  • the carriage 13 is also equipped with cutters 27, rotatably mounted in bearings 28 whose active face extends in the same plane as the active face of cutters 23.
  • these cutters can- they attack the front surface 4a of the threshold of the door frame C.
  • the strawberries 27 are extended by a tail 29 ending in a toothed wheel 30 which meshes with a rack 31 provided along the lower edge of the fixed frame 11. The movement of the carriage generates the horizontal displacement of the cutters 27 and their rotation in the bearings 28.
  • FIG. 5 schematically illustrates the mounting of a milling cutter 23 or 27 in a bearing 22 or 28.
  • the tail 24 or 29 has inside the bearing, a shoulder 32 on which acts an axial return spring 33 of the milling cutter in the direction of its application on the surface to be cleaned.
  • the spacing of the consecutive cutters will, for the lateral cutters 23, at most equal to the stroke of the piston of the jack 21, so that there is overlap of the distances traveled by two consecutive cutters.
  • their spacing will depend on their number and on the stroke of the carriage.
  • FIG. 2 also represents two series 34 and 35 of scraping tools 36.
  • Each tool 36 consists of two blades 36a and 36b, the active edges 37 of which cooperate with the interior surfaces 1b and 2b of the uprights 1 and 2 of the frame C.
  • each pair of blades 36 is fixed to the frame 12 by means of a block 38 of elastic fixing at least in one direction so that when approaching the device towards the frame to be cleaned, the tools 36 are constantly held against the surfaces 1b, 2b. In most cases, these surfaces form a draft, that is to say converge towards the interior of the furnace, which facilitates the application in good conditions of the scraper blades 36 including the active edge 37, by construction.
  • for each side is contained in a plane which converges to a symmetrical plane containing the active edges of the blades on the other side, at the same angle as that of convergence of the interior surfaces of the door frame.
  • FIG. 2 we finally see a blade 40 at the upper part of the frame 12, of width equal to the width of the frame C, which constitutes a scraping tool for the surface 3a of the front of the lintel 3 of the door frame.
  • the blade is also coupled to the frame 12 by means of resilient fixing blocks.
  • FIG. 7 is a diagram which wants to illustrate the drive mechanism of the carriage 13 in its lower horizontal movement, by the only transformation of the movement of the frame 12 relative to the frame 11.
  • the carriage 13 is shown diagrammatically as being able to slide on the frame 11 in slideways 41.
  • the frame 12 carries a rack 42, on which a toothed wheel 43 meshes, rotatably mounted around an axis 44 which belongs to the frame 11, in extending perpendicular to the plane in which the relative movement of the two frames takes place.
  • This wheel 43 carries an eccentric finger 45 to be able to play the role of a cam, which is coupled to a lever 46, between one of its end 46a where it is articulated to the fixed frame 11, and its other end 46b, where it is coupled to the carriage 13 by means of a connection which has a degree of freedom in the vertical direction (so that the movement in an arc of a circle of the end 46b can generate a rectilinear movement).
  • This diagram shows that the back-and-forth movement of the frame 12 relative to the frame 11 causes the translation of the rack 42, and therefore the rotation of the wheel 43.
  • the finger 45 therefore causes the lever 46 to oscillate, which in turn generates the reciprocating rectilinear movement of the carriage 13.
  • the cleaning of the oven floor and the door threshold is done in a conventional manner, thanks to a squeegee placed in front of the frame 12 and coupled to the frame 11.
  • the invention finds an interesting application in the field of equipment for carbochemistry.
