[0068] Embodiment 1

[0069] A combined closed solid material roll pressing treatment system provided in Embodiment 1 of the present application, see Figure 3 , including a roll press B arranged in the roll pressing area and a slag tank tipping machine C carrying a slag tank D;

[0070] The outer cover of the roll press B is provided with a roll press cover B6, and the roll press B is fixed on both sides of the roll press cover B6 to drive the roll press cover B6 to move. The tail end of the roll press cover B6 is wrapped and provided with a rear fixed cover A, and the gap between the roll press cover B6 and the rear fixed cover A is sealed by a sealing device;

[0071] An active cover door device is arranged at the inlet end of the roll press cover B6. The active cover door device includes an active cover door B3 arranged at the inlet end of the roll press cover B6 and a door pushing device C3 on the slag tank tipping machine C. The door pushing device C3 moves forward to push open the active cover door B3 or moves backward to close the active cover door B3.

[0072] In an embodiment of the present application, the upper part of the rear wall of the rear fixed cover A is sequentially connected to a reduced-diameter section A2 pipe with a gradually decreasing diameter and an air pipe A1, and then connected to an external dust removal device.

[0073] In an embodiment of the present application, a cooling device B1 is provided on the roller press B. The cooling device B1 includes a water pipe and a nozzle. The water pipe is installed on the roller press crossbeam B7 of the roller press B, with the outlet end connected to the nozzle and the inlet end connected to an external water pipe.

[0074] Further, the number of the water pipes and nozzles can be set to 2 to 4 rows, with 1 to 3 in each row.

[0075] In an embodiment of the present application, a cyclone dust removal structure is provided at a position of the rear fixed cover A close to the variable diameter section A2, so that the fine particles in the dust-containing flue gas return to the roller bed E at the bottom of the roller press B through cyclone dust removal and gravity sedimentation.

[0076] In an embodiment of the present application, a discharge port F is provided on the roller bed E at the bottom of the roller press B, and a storage device G is provided below the discharge port F for the storage and transportation of materials.

[0077] In an embodiment of the present application, the driving device of the roller press B is isolated outside the combined sealing device and moves synchronously with the roller press B and the roller press cover B6.

[0078] In an embodiment of the present application, referring to Figure 4 、 5 , the external shape of the roller press cover B6 is an inverted U shape, and both side walls are seated on the top planes of the two vertical side plates of the roller bed E in the rolling area; the rear fixed cover A includes a cover body A3, and the external shape of the cover body A3 is an inverted U shape, and both side walls are seated on the top planes of the two vertical side plates of the roller bed E in the rolling area; in the cross-sectional direction, the cover body A3 is located inside the roller press cover B6; gaps A4 are provided in the middle of both side walls of the cover body A3, and the gaps A4 are sealed with high-temperature resistant soft sealing materials; the gaps A4 are used to prevent interference between the roller press B and the cover body A3.

[0079] In an embodiment of the present application, the roller press cover B6 is installed on the roller press crossbeam B7 of the roller press B and moves synchronously with the movement of the roller press B. Both side walls of the roller press cover B6 and the rear fixed cover A are seated on the top planes of the two vertical side plates of the roller bed E in the rolling area and have a small gap with this plane, and this small gap is sealed with high-temperature resistant soft sealing. Exemplarily, the seals are respectively fixed at the bottoms of both side walls of the roller press cover B6 and both side walls of the rear fixed cover A, and the seals move and seal on the top planes of the two vertical side plates of the roller bed E.

[0080] In an embodiment of the present application, the sealing device includes a high-temperature resistant soft sealing material plug, that is, a high-temperature resistant soft sealing material plug is provided in the gap between the cover A3 and the roller press cover B6. The fixed cover A3 and the roller press cover B6 are fitted in size from the inside to the outside, and the gap between the covers is plugged by a high-temperature resistant soft sealing material to achieve a sealing effect. Exemplarily, the plug is fixed to the inner wall of the roller press cover B6 and moves on the outer wall of the fixed cover A3 to seal the gap when the roller press cover B6 moves.

[0081] In an embodiment of the present application, referring to Figure 3 , the movable cover door B3 includes a door body lifting member B9 provided on its outer side, and the door body lifting member B9 is a wedge-shaped member with a narrower upper part and a wider lower part; the door pushing device C3 is a plate or column fixed and standing on the cross beam C2, and the door pushing device C3 advances or retreats along the wedge surface of the door body lifting member B9.

[0082] In an embodiment of the present application, slag baffle plates C1 are provided on both sides of the slag ladle tilter C. The distance between the outer walls of the two slag baffle plates C1 is smaller than the distance between the inner walls of the roller press cover B6, and a high-temperature resistant soft sealing plug is provided between the slag baffle plate C1 and the roller press cover B6. Exemplarily, this plug is fixed to the outside of the slag baffle plate C1 and moves on the inner wall of the roller press cover B6 to seal the gap between the slag baffle plate C1 and the roller press cover B6 when the slag baffle plate C1 moves.

[0083] In the present application, through the combined sealing of the roller press cover B6, its inlet end movable cover door device, and the rear-end fixed cover A, dust is enclosed in a sealed space, and the dust-containing flue gas in the sealed space is sucked to an external dust removal device through the air duct A1 for dust removal treatment. At the same time, the roller pressing area cooling device cools the molten steel slag by spraying water.

[0084] Since the driving device of the roller press B in the present application is isolated outside the combined sealed solid material roller pressing treatment system and moves synchronously with the roller press B and the roller press cover B6, the accumulation of dust on the driving device of the roller press B is avoided, which is beneficial to protecting the equipment and prolonging its service life; also, since the slag ladle tilter only enters the roller press cover B6 to discharge materials during the roller pressing gap, the accumulation of dust on the slag ladle tilter is also avoided; at the same time, both ends are effectively closed during the roller pressing process to avoid the overflow of soot; since it is not necessary to cover all of the slag ladle tilter C and the conveying track, etc., the volume of the sealed cover is reduced, so the dust removal air volume is correspondingly reduced, and the configuration requirements for subsequent dust removal facilities and water treatment facilities are both reduced, greatly saving the project cost and operating expenses.

[0085] The movable hood B3 is automatically lifted or lowered by the door-pushing device C3, and there is no need for on-site operators to additionally operate the jog button for opening and closing. Moreover, due to the setting of the door-lifting component B9, it is convenient for automatic door-pushing and avoids the door-pushing device directly contacting the door body of the movable hood B3, preventing the door body from being damaged by the slag ladle tilting machine C or burned by the high-temperature molten steel slag on the slag ladle tilting machine C, bringing a lot of convenience to on-site operation and maintenance.

[0086] Embodiment 2

[0087] In this Embodiment 2, to extend the length of the sealed area of the roll-pressing zone, facilitate the accommodation and treatment of more solid materials, and provide more space for the roll press B to perform roll-pressing, a translation hood H can be further provided at the tail of the roll press hood B6.

[0088] In an embodiment of the present application, a translation hood H is provided at the connection position between the hood body A3 and the roll press hood B6. The shape of the hood body A3 is an inverted U shape, and its two side walls are seated on the top planes of the two vertical side plates of the roll bed E. In the cross-sectional direction, the translation hood H is located outside the hood body A3 and inside the roll press hood B6; a track A8 is provided at the top of the hood body A3, and a wheel pair H2 is provided at the bottom of the top panel of the translation hood H to drive it to move along the track A8.

[0089] In an embodiment of the present application, the two side walls of the hood body A3 are seated on the top planes of the two vertical side plates of the roll bed E.

[0090] In an embodiment of the present application, the gaps between the hood body A3, the translation hood H, and the roll press hood B6 are sealed with high-temperature resistant soft sealing materials.

[0091] In an embodiment of the present application, car stops A6 are provided at both the front and rear of the track A8 for physically limiting the translation hood H.

[0092] In an embodiment of the present application, a clamping seat three H3 and a clamping seat two B10 that mutually clamp are provided between the translation hood H and the roll press hood B6, and the translation hood H is applied with a walking power through the mutual action of the clamping seat three H3 and the clamping seat two B10.

[0093] In an embodiment of the present application, both the clamping seat three H3 and the clamping seat two B10 are L-shaped and are arranged in a relatively occluding and clamping manner. The horizontal first arm of the clamping seat three H3 is fixed to the bottom of the top panel of the translation hood H, and the vertical second arm is arranged on the side away from the translation hood H. The horizontal first arm of the clamping seat two B10 is fixed to the top of the top panel of the roll press hood B6, and the vertical second arm is arranged on the side close to the translation hood H and is attached to the vertical second arm of the clamping seat three H3.

[0094] The translation cover H is placed on the track A8 through the wheel set H2, and the driving force is applied to the roller press cover B6 through the roller press cross beam B7 of the roller press B. The interaction between the third clamp H3 and the second clamp B10 applies a pushing and pulling force for the translation cover H to move, so as to drive the translation cover H to move without power. The fixed cover A3, the translation cover body H1, and the roller press cover B6 are nested in order of size from the inside to the outside. The gaps between the covers are sealed by high-temperature resistant soft sealing materials to achieve a sealing effect.

[0095] Specifically, referring to Figure 3 , the right side of the translation cover H is connected to the second clamp B10 and the roller press cover B6 by setting the third clamp H3. The gap between the left side of the translation cover H and the cover body A3 is sealed by high-temperature resistant soft sealing materials. Exemplarily, it can be fixedly sealed on the left side of the translation cover H, and the seal extends towards the cover body A3. When the translation cover H moves, it drives the seal H4 to move on the cover body A3 and seals the gap. The combination of the third clamp H3 and the second clamp B10 plays a role in sealing. It can also be further fixedly sealed on the right side of the translation cover H, and the seal extends towards the upper roller press cover B6 to seal the gap between the translation cover H and the roller press cover B6.

[0096] Embodiment 3

[0097] Based on Embodiment 1, in this Embodiment 3, it is further set that the movable cover door B3 is arranged at the entrance of the roller press cover B6 and is rotatably connected to the upper sill above it; the door pushing device C3 is arranged on the tilting machine cross beam C2 at the front of the slag pot tilting machine C.

[0098] In an embodiment of the present application, an upper sill is arranged at the entrance end of the roller press cover B6, and the upper sill is fixedly connected to the top and both sides of the entrance end of the roller press cover B6. The movable cover door B3 is rotatably connected to the bottom of the upper sill through a hinge B4.

[0099] In an embodiment of the present application, a physical limit door suction B8 is arranged between the movable cover door B3 and the entrance end of the roller press cover B6. The physical limit door suction B8 is used to adsorb and fix the inner wall of the movable cover door B3 in the vertical direction when the movable cover door B3 falls and closes.

[0100] In an embodiment of the present application, the first pole of the physical limit door suction B8 is arranged on both sides of the movable cover door B3, and the second pole of the physical limit door suction B8 is arranged on the inner side of the entrance end of the roller press cover B6. When the first pole and the second pole attract each other, the movable cover door B3 is in a vertical state to close the entrance end of the roller press cover B6.

[0101] In an embodiment of the present application, a slag pot D is arranged on the slag pot tilting machine C. The slag pot tilting machine C is used to pour the molten steel slag or other types of solid waste slag to be roller pressed in the slag pot D into the roller pressing area.

[0102] In an embodiment of the present application, notches two B2 are provided at the inlet ends of the two side walls of the roller press cover B6, so that when the slag pot tipper C travels, the tipper cross beam C2 thereon does not interfere with the roller press cover B6.

[0103] In an embodiment of the present application, the notches two B2 are installed with a high-temperature resistant soft seal material for plugging.

[0104] During the process that the slag pot tipper C travels along the track direction and enters the roller table, the pushing door device C3 carried on the tipper cross beam C2 pushes the movable hood door B3 from the vertical direction to the upper side. When the slag pot tipper C dumps the molten steel slag in the slag pot D, the movable hood door B3 is in the upper position. After the slag pot tipper C exits the rolling area, the movable hood door B3 returns to the vertical state, being part of the combined closed solid material roller pressing treatment system.

[0105] In the present application, this system is applicable regardless of whether the discharge port F and the conveying system G are arranged at the front end or the rear end of the rolling area.

[0106] The process of rolling using the combined closed solid material roller pressing treatment system provided by one of the embodiments of the present application is as follows: The slag pot tipper C carries the slag pot D into the rolling area, and the two side baffles C1 and the cover body A3 form a seal simultaneously. The slag pot tipper C and the slag pot D itself also form a sealing effect on the roller press cover B6 transversely. When the pushing door device C3 is a plate member, it further plays a sealing role transversely. During the process that the slag pot tipper C travels along the track direction and enters the roller table E, the pushing door device C3 carried on the tipper cross beam C2 pushes the movable hood door B3 from the vertical direction around the hinge B4 to the upper side, and the slag pot tipper C dumps the molten steel slag in the slag pot D onto the roller table E. At this time, the movable hood door B3 is in the upper position.

[0107] After the slag pot tipper C exits the rolling area, the movable hood door B3 slowly drops along the pushing door device C3 through the door body lifting component B9, and is physically positioned and attracted by the physical limit door magnet B8, and returns to the vertical state. The physical limit door magnet B8 on the outer frame of the movable hood door B3 prevents the movable hood door B3 from opening outward. When the tipper C enters the rolling area, it automatically opens and raises the movable hood door B3, without affecting the slag dumping action of the tipper C; and when the tipper C finishes dumping the slag and leaves the rolling area, it automatically makes the hood door fall, forming a closed space, and then rolling is carried out, and the dust during the rolling process is enclosed in the closed space to prevent the smoke and dust from overflowing.

[0108] After the movable hood B3 descends to close the roller press hood B6, the roller press B rolls and crushes the molten steel slag back and forth within the range of the roller table E. After the rolling and crushing is completed, the slag is pushed to the discharge opening F of the roller table. There is a storage device G below the discharge opening F for the storage and transportation of materials. During the rolling and crushing process, the cooling device B1 sprays water to cool the molten steel slag. The generated flue gas is captured by the combined airtight system composed of the roller press hood B6, the movable hood B3, the roller table E, etc., and is sucked into the subsequent dust removal system through the fixed hood A at the rear end, the translation hood H and the air duct A1.

[0109] In the above process, the slag pot tilter C can enter and exit the roller press hood B6 at set time intervals and durations. It enters the roller press hood B6 under set conditions (such as when the roller press B stops, and the flue gas concentration is lower than the first threshold, and the temperature is lower than the second threshold), automatically discharges the material (taking the set duration from the start of discharging as the sign of discharging completion), and exits the roller press hood B6. This process can be set through a PLC controller, etc. to achieve automated rolling. Among them, the flue gas concentration and temperature can be measured by sensors, and the duration and frequency can be set by a timer and a timer. The focus of this application is to provide the structural composition of a combined airtight solid material rolling and processing system, so the control process will not be elaborated.

[0110] Furthermore, the roller press B has a roller body B5 for rolling and crushing and a push plate (not shown in the figure) for pushing the steel slag, and commercially available equipment can be used.

[0111] Furthermore, when spraying water, the cooling device can adopt the method of reducing the water volume to make the best use of the waste heat of the molten steel slag.

[0112] The translation hood H is a supplement to the airtight length of the rolling area. If the space is sufficient, the translation hood H can be omitted.

[0114] The above are only the embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the scope of the claims of this application.
