Description

Technical Field

[0001] This application relates to the field of solid waste treatment, and specifically relates to a combined closed solid material roll pressing treatment system. Background Art

[0002] At present, the main methods for treating steel slag include hot pouring method, thermal soaking method, water quenching method, air quenching method, roller method, granulation method, etc. Among them, the thermal soaking method can fully carry out the digestion reaction of free calcium oxide and free magnesium oxide in the steel slag, eliminating the unstable factors of the steel slag. It is the most effective method that takes into account the comprehensive utilization, high-value utilization, energy conservation and environmental protection of the steel slag, and has been more and more widely used. One of the technological processes of steel slag thermal soaking is to crush the steel slag before thermal soaking treatment so that the steel slag can fully carry out the digestion reaction during thermal soaking. The steel slag crushing process applies a slag ladle tilter and a roll press. The slag ladle tilter pours the molten steel slag into the roll pressing area through the slag ladle, and the roll press crushes the steel slag through roll pressing treatment, and the cooling water cools down the molten steel slag.

[0003] However, in the traditional treatment process, due to the large amount and high humidity of the generated dust, the amount of dust on the slag ladle tilter and the roll press is large. Especially, the driving system is covered with dust, which is easy to damage the equipment. Secondly, the existing closed cover in the roll pressing area covers all the equipment, and one side cannot be effectively closed, resulting in the overflow of smoke and dust. Thirdly, the volume of the closed cover is too large, so the corresponding dust removal air volume increases, and the subsequent dust removal facilities and water treatment facilities are configured too high, greatly increasing the project cost and operation cost.

[0004] In addition, the traditional roll pressing treatment device needs to block the outlet of the closed cover after the tilter exits the roll pressing area to prevent the overflow of flue gas. Previously, the opening and closing of the blocking door required the on-site operator to additionally operate the jog button, which brought inconvenience to the operator. Moreover, the blocking door was easily damaged by the tilter or burned by the high-temperature molten steel slag on the tilter, bringing many difficulties to the on-site operation and maintenance. Summary of the Invention

[0005] To at least partially solve the above problems, this application provides a combined closed solid material roll pressing treatment system, which can achieve efficient sealing and reduce the damage of smoke and dust to the equipment, without additional operation by the operator and is strong and durable.

[0012] In an alternative embodiment, a discharge port is provided on the roller table at the bottom of the roller press, and a storage device is provided below the discharge port for material storage and transportation.

[0013] In an alternative embodiment, the driving device of the roller press is isolated outside the combined sealing device and moves synchronously with the roller press and the roller press hood.

[0014] In an alternative embodiment, the outer shape of the roller press hood is inverted, and both side walls are located on the top plane of the two vertical side plates of the roller table in the rolling area; the rear fixed hood includes a hood body, the outer shape of the hood body is inverted, and both side walls are located on the top plane of the two vertical side plates of the roller table in the rolling area; in the cross-sectional direction, the hood body is located inside the roller press hood; gaps are provided in the middle of both side walls of the hood body, and the gaps are sealed with high-temperature resistant soft sealing materials; the gaps are used to prevent interference between the roller press and the hood body.

[0015] In an alternative embodiment, the gap between the hood body and the roller press hood is sealed with high-temperature resistant soft sealing materials.

[0016] In an alternative embodiment, the active hood door includes a door body lifting component provided on its outer side. The door body lifting component is a wedge-shaped component with a narrower upper part and a wider lower part; the door pushing device is a plate or column fixed and standing on the crossbeam, and the door pushing device advances or retreats along the wedge surface of the door body lifting component.

Since the driving device of the roll press in the present application is isolated outside the combined closed solid material roll pressing treatment system and moves synchronously with the roll press and the roll press cover, it avoids dust accumulation on the driving device of the roll press, is beneficial to protecting the equipment and extending its service life; also, since the slag pot tilter only enters the roll press cover to unload materials during the roll pressing gap, it also avoids dust accumulation on the slag pot tilter; at the same time, both ends are effectively closed during the roll pressing process to avoid smoke and dust overflow; since it is not necessary to completely cover the slag pot tilter and the conveying track, etc., the volume of the closed 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 operation cost. The movable cover door is automatically lifted or lowered by a door pushing device, and there is no need for on-site operators to additionally operate a jog button for opening and closing. Moreover, due to the setting of a door body lifting component, it is convenient for automatic door pushing and also avoids the door pushing device directly contacting the door body of the movable cover door, preventing the door body from being damaged by the slag pot tilter or being burned by the high-temperature molten steel slag on the slag pot tilter, bringing a lot of convenience to on-site operation and maintenance.

[0033] The present application provides a combined closed solid material roller pressing treatment system for performing closed dust collection and cooling during the roller pressing operation.

[0034] Embodiment 1

The pushing door device C3 advances to push open the activity hood door B3 or retreats to close the activity hood door B3.

[0038] 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 a duct A1, and then connected to an external dust removal device.

[0039] In an embodiment of the present application, a cooling device B1 is provided on the roll press B. The cooling device B1 includes a water pipe and a nozzle. The water pipe is installed on the roll press crossbeam B7 of the roll press B, the outlet end is connected to the nozzle, and the inlet end is connected to an external water pipe.

[0040] Furthermore, the number of the water pipes and nozzles can be set to 2 to 4 rows, with 1 to 3 in each row.

[0041] In an embodiment of the present application, a cyclone dust removal structure is provided at the position of the rear fixed cover A close to the reduced-diameter section A2, so that the fine particles in the dusty flue gas return to the roll bed E at the bottom of the roll press B through cyclone dust removal and gravity sedimentation.

[0042] In an embodiment of the present application, a discharge port F is provided on the roll bed E at the bottom of the roll press B, and a storage device G is provided below the discharge port F for material storage and transportation.

[0043] In an embodiment of the present application, the drive device of the roll press B is isolated outside the combined sealing device and moves synchronously with the roll press B and the roll press cover B6.

[0044] In an embodiment of the present application, referring to Figure 2 , the external shape of the roll press cover B6 is an inverted U shape, and both side walls are located on the top planes of the two vertical side plates of the roll 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 located on the top planes of the two vertical side plates of the roll bed E in the rolling area; in the cross-sectional direction, the cover body A3 is located inside the roll press cover B6; a notch A4 is provided in the middle of both side walls of the cover body A3, and the notch A4 is sealed with a high-temperature resistant soft sealing material; the notch A4 is used to prevent interference between the roll press B and the cover body A3.

[0045] In an embodiment of the present application, the roll press cover B6 is installed on the roll press crossbeam B7 of the roll press B and moves synchronously with the movement of the roll press B. Both side walls of the roll press cover B6 and the rear fixed cover A are located on the top planes of the two vertical side plates of the roll bed E in the rolling area and have a small gap with this plane, and this small gap is sealed with a high-temperature soft seal. Exemplarily, the seals are respectively fixed at the bottoms of both side walls of the roll 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 roll bed E.

[0046] In an embodiment of the present application, the sealing device includes a high-temperature resistant soft sealing material plugging, that is, a high-temperature resistant soft sealing material plugging 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 from the inside to the outside in terms of size, and the gaps between the covers are plugged by a high-temperature resistant soft sealing material to achieve a closed effect. Exemplarily, the plugging here is fixed on the inner wall of the roller press cover B6 and moves on the outer wall of the fixed cover A3 and seals the gap as the roller press cover B6 moves.

[0047] In an embodiment of the present application, referring to Figure 1 , the movable cover door B3 includes a door body lifting component B9 provided on its outer side, and the door body lifting component B9 is a wedge-shaped component 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 component B9.

[0048] In an embodiment of the present application, slag retaining plates C1 are provided on both sides of the slag ladle tilter C. The distance between the outer walls of the two slag retaining plates C1 is smaller than the distance between the inner walls of the roller press cover B6, and a high-temperature resistant soft sealing plugging is provided between the slag retaining plates C1 and the roller press cover B6. Exemplarily, this plugging is fixed on the outer side of the slag retaining plates C1 and moves on the inner wall of the roller press cover B6 and seals the gap between the slag retaining plates C1 and the roller press cover B6 as the slag plates C1 move.

[0049] 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, the dust is enclosed in a closed space, and the dust-containing flue gas in the closed space is sucked to an external dust removal device for dust removal treatment through the air duct A1. At the same time, the roller pressing area cooling device cools the molten steel slag by spraying water.

[0050] 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 extending its service life; and since the slag ladle tilter only enters the roller press cover B6 for discharging 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 smoke and dust; 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 operation cost.

[0051] 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 jogging button for opening and closing. Moreover, due to the setting of the door-lifting component B9, it is not only convenient for automatic door pushing but also avoids the direct contact between the door-pushing device and the door body of the movable hood B3, preventing the door body from being damaged by the slag ladle tilter C or burned by the high-temperature molten steel slag on the slag ladle tilter C, bringing a lot of convenience to on-site operation and maintenance.

[0052] Embodiment 2

[0053] In this Embodiment 2, to extend the length of the sealed area of the roll-pressing zone, facilitate the accommodation and processing of more solid materials, and provide more space for the roll press B for roll pressing, a translation hood H can be further provided at the tail of the roll press hood B6.

[0054] In an implementation manner 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 hood body A3 is in the shape of an inverted U, 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 set H2 is provided at the bottom of the top panel of the translation hood H to drive it to move along the track A8.

[0055] In an implementation manner 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.

[0056] In an implementation manner 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.

[0057] In an implementation manner 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.

[0058] In an implementation manner of the present application, a mutually clamping seat three H3 and seat two B10 are provided between the translation hood H and the roll press hood B6, and the mutual action between the seat three H3 and the seat two B10 applies a driving force to the translation hood H.

[0059] In an implementation manner of the present application, both the seat three H3 and the seat two B10 are L-shaped, and are relatively set in a clamping and engaging manner. The horizontal first arm of the seat three H3 is fixed to the bottom of the top panel of the translation hood H, and the vertical second arm is provided on the side away from the translation hood H. The horizontal first arm of the seat two B10 is fixed to the top of the top panel of the roll press hood B6, and the vertical second arm is provided on the side close to the translation hood H and is attached to the vertical second arm of the seat three H3.

[0060] 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 the 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 the airtight effect.

[0061] Specifically, referring to Figure 1 , 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.

[0062] Embodiment 3

[0063] 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.

[0064] 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.

[0065] In an embodiment of the present application, a physical limit door sucker B8 is arranged between the movable cover door B3 and the entrance end of the roller press cover B6. The physical limit door sucker 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.

[0066] In an embodiment of the present application, the first pole of the physical limit door sucker B8 is arranged on both sides of the movable cover door B3, and the second pole of the physical limit door sucker 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.

[0067] 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.

[0068] In an embodiment of the present application, notches two B2 are formed at the inlet ends of the two side walls of the roll press housing B6, so that when the slag ladle tilter C is moving, the tilter cross beam C2 thereon does not interfere with the roll press housing B6.

[0069] In an embodiment of the present application, the notches two B2 are installed with a high-temperature resistant soft sealing material for blocking.

[0070] When the slag ladle tilter C moves along the track direction and enters the roll table, the pushing door device C3 carried on the tilter cross beam C2 pushes the movable hood door B3 from the vertical direction to above. When the slag ladle tilter C is pouring the molten steel slag in the slag ladle D, the movable hood door B3 is in the upper position. After the slag ladle tilter C exits the rolling area, the movable hood door B3 returns to the vertical state, being part of the combined closed solid material roll pressing treatment system.

[0071] 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.

[0072] The process of roll pressing using the combined closed solid material roll pressing treatment system provided by one of the embodiments of the present application is as follows: The slag ladle tilter C carrying the slag ladle D enters the rolling area, and the two side baffles C1 and the housing A3 form a seal at the same time. The slag ladle tilter C and the slag ladle D itself also form a sealing effect on the roll press housing B6 transversely. When the pushing door device C3 is a plate member, it further plays a sealing role transversely. When the slag ladle tilter C moves along the track direction and enters the roll table E, the pushing door device C3 carried on the tilter cross beam C2 pushes the movable hood door B3 from the vertical direction around the hinge B4 to above. The slag ladle tilter C pours the molten steel slag in the slag ladle D onto the roll table E, and at this time the movable hood door B3 is in the upper position.

[0073] After the slag ladle tilter 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 stopper B8, and returns to the vertical state. The physical limit door stopper B8 on the outer frame of the movable hood door B3 prevents the movable hood door B3 from opening outwards. When the tilter C enters the rolling area, the movable hood door B3 is automatically opened and lifted, without affecting the slag pouring action of the tilter C; and when the tilter C finishes pouring the slag and leaves the rolling area, the hood door is automatically lowered to form a closed space, and then roll pressing is carried out, and the dust during the roll pressing process is enclosed in the closed space to prevent the smoke and dust from overflowing.

[0074] 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 rear fixed hood A, the translation hood H and the air duct A1.

[0075] During the above process, the slag ladle tipper 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 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 treatment system, so the control process will not be elaborated.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] For the high-temperature soft seal plugging of each gap in this application, reference can be made to Figure 2 the plugging structure schematic diagram numbered H4.

[0080] 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.
