DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0022] like Figures 1 to 3 As shown, a non-powered coal-loading and dust-removing false furnace door specially used for side-loading coal-type coke ovens comprises an ordinary furnace head dust collecting and suction device 1 and a double-row self-positioning pulley set 2. A false furnace door positioning slide rail 7 is fixedly installed on the side of the ordinary furnace head dust collecting and suction device 1. A double-row self-positioning pulley set 2 is installed on the false furnace door positioning slide rail 7. Automatic positioning sliding balls 3 are arranged between the double-row self-positioning pulley sets 2. The lower positions of both ends of the double-row self-positioning pulley set 2 are fixedly connected to the fire-proof false furnace door 4. Elastic electromagnetic traction discs 5 are arranged on both sides of the fire-proof false furnace door 4. A vehicle-mounted electromagnetic traction device 6 is arranged on the outer side of the elastic electromagnetic traction disc 5. The ordinary furnace head dust collecting and suction device 1 is installed above the furnace door between the furnace columns 9, and a false furnace door lower limit track 8 is arranged below the furnace column 9.

[0023] Among them, the double-row self-positioning pulley group 2 is composed of two sets of left and right suspended sliding rollers, which are used for the false furnace door to move on the guide rail.

[0024] The automatic positioning sliding ball 3 is arranged in the middle position of the double-row self-positioning pulley group 2 and is used for automatic alignment of the false furnace door.

[0025] The outside of the fireproof false furnace door 4 is welded with fireproof stainless steel plates, and a fireproof and high-temperature resistant sealing material is provided on the inside. High-temperature resistant and fireproof sealing soft brushes are configured around it to seal the furnace door area so that smoke and dust cannot be blown away by the wind.

[0026] The vehicle-mounted electromagnetic traction device 6 is installed on one side of the coal charging car and the coke pushing car, and is used to pull and push the false furnace door to the corresponding position.

[0027] The positioning slide rail 7 on the false furnace door is an H-shaped self-positioning slide rail.

[0028] The working principle of the utility model is as follows: an ordinary furnace head dust collecting and suction device 1 is installed between the furnace column 9 and above the furnace door. Before installing the false furnace door, the flatness needs to be adjusted according to the deformation of the coke oven column 9 to make the false furnace door run more smoothly. The positioning slide rail 7 on the false furnace door is installed and connected to the ordinary furnace head dust collecting and suction device 1 by bolting the base or directly welding. The track is an H-shaped self-positioning slide rail with a positioning pulley positioning hole. The lower limit track 8 of the false furnace door is installed. The slide rail bracket is first welded on the furnace column 9, and then the slide rail is connected by bolts. The straightness of the slide rail is adjusted to be parallel to the positioning slide rail 7 on the false furnace door. The self-positioning sliding ball is installed and installed on the double-row self-positioning pulley group 2 connecting support After the installation is completed, use the adjusting nut to adjust the sliding ball to the appropriate position, install the double-row self-positioning pulley set 2, and install the double-row sliding wheel equipped with self-positioning sliding ball on the reserved position on the upper part of the fire-proof false furnace door 4 by bolt connection; install the vehicle-mounted electromagnetic traction device 6, and install the elastic electromagnetic traction disc 5 on the reserved positions on both sides of the fire-proof false furnace door 4 by bolts, install the fire-proof false furnace door 4, and hang the false furnace door equipped with the elastic electromagnetic traction disc 5 and the double-row self-positioning pulley set 2 on the positioning slide rail 7 on the false furnace door, then place the U-shaped groove at the bottom of the false furnace door on the lower limit track 8 of the false furnace door, and finally push it manually to observe whether there are other effects;

[0029] Install the vehicle-mounted electromagnetic traction device 6. Install the four false furnace door vehicle-mounted electromagnetic traction devices 6 on the coke pusher and coal charging car respectively. Adjust the installation angle so that it can fit more tightly with the elastic electromagnetic traction disc 5. Finally, install the electrical control system in the driver's cab. After completion, perform overall debugging and continue to adjust until stable operation.

[0030] The ordinary furnace head dust collecting and suction device 1 is used to collect the smoke and dust floating up under the action of thermal buoyancy. The positioning slide rail 7 on the false furnace door is fixed on it. The elastic electromagnetic traction disc 5 can effectively prevent the vehicle from driving too fast and knocking the furnace door out of the production area. It can also be used to better align the traction device, so that the entire false furnace door is connected to the vehicle body more smoothly. The positioning slide rail 7 on the false furnace door is installed on the furnace head cover or the furnace column 9. It is the mobile guide rail of the false furnace door. Each furnace number position is provided with a positioning hole, which effectively solves the positioning problem of the false furnace door. The lower limit rail 8 of the false furnace door is connected to the bottom of the furnace column 9, which is used to fix the false furnace door to prevent it from swinging with the wind.

[0031] The fireproof false furnace door 4 is located between the coke pushing car and the coal loading car. The operation sequence is as follows: during the coke oven production process, the fireproof false furnace door 4 is always attracted to the side of the coke pushing car by the vehicle-mounted electromagnetic traction device 6 and moves with the coke pushing car. There are two ways to align the fireproof false furnace door 4. One is manual alignment. When the driver pulls the false furnace door to the coke outlet hole N, the electromagnetic traction device is closed after the positioning ball makes a positioning sound to determine whether it is in place. The other way is inertial automatic alignment. When the driver pulls the false furnace door to the hole N-1 before the coke outlet hole, the electromagnetic traction device is directly closed, so that the false furnace door moves to the coke outlet hole N on the track by inertia. When in place, the self-positioning sliding ball will be embedded in the positioning hole of the positioning slide rail to complete the positioning.

[0032] When the coke pushing car finishes pushing the coke, it first pulls the false furnace door to the coke oven hole N, and releases the traction device after alignment. At this time, the coal charging car has been loaded with coal and is ready to drive to the coke oven hole N to fill the carbonization chamber. When the coal charging car arrives at the position N-1 before the coke oven hole, the electromagnetic traction device is started, and the fire-proof false furnace door 4 is first sucked together with one side of the coal charging car, and then pushed away from the coke oven, and then the coal charging car is aligned to fill the coal. After the filling is completed, the coal charging car pulls the fire-proof false furnace door 4 to the coal charging furnace hole to temporarily close the furnace door. Then, when the coke pushing car drives to the corresponding position, the electromagnetic traction device is started again to suck the furnace door together with one side, and finally the furnace door cover is closed, thereby completing one production, and then the operation is repeated in this way.

[0033] The utility model discloses a non-powered coal loading and dust removal false furnace door, whose component equipment are all detachably assembled and the standardized equipment connection can make the entire system run more stably and the maintenance more convenient, reducing the production problems caused by equipment failure, and at the same time can solve the problem of smoke and dust that cannot be collected by the furnace head cover after the coal loading is completed and the coal loading vehicle leaves, thereby avoiding environmental pollution.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
