At the same time, by arranging the overturning structure 200, the overhead crane is not needed to pour the slag, and the work efficiency is improved.

[0055] Specifically in the embodiment, the braising pool 100 is generally in a cubic structure, the four side walls and the bottom wall of the braising pool 100 are connected to form the inner cavity 110 of the braising pool 100, the top of the braising pool 100 is formed with the lifting opening 120, and the diameter of the lifting opening 120 is limited to the condition that the overhead crane hook or other lifting tools can lift the slag tank 400 into the inner cavity 110 of the braising pool 100 from the lifting opening 120.

[0056] In the embodiment, the rack 210 of the overturning structure 200 is arranged in the inner cavity 110, and the rack 210 is arranged directly below the lifting opening 120 in the height direction, so as to vertically lift the slag tank 400 from the lifting opening 120 to the rack 210, in the embodiment, the rack 210 of the overturning structure 200 can rotate around the rotation axis, so as to overturn the slag tank 400 arranged on the rack 210 downward, and the molten slag in the slag tank 400 can be poured into the bottom of the braising pool 100; in the embodiment, the equipment for overturning the rack 210 is not limited, and the tool capable of driving the rack 210 to overturn is limited.

[0057] In the embodiment, the dust cover 310 of the dust removal structure 300 is used to seal the hoisting opening 120, so as to avoid that the smoke generated by the hot stewing of the molten slag from the hoisting opening 120 when the molten slag is poured and when the spraying assembly 320 sprays the molten slag, and to avoid the influence on the environmental safety. In the embodiment, the dust cover 310 is movably arranged, that is, the dust cover 310 can move at the upper end of the stewing slag pool 100. In a specific embodiment, a sliding track is arranged at the upper end of the side wall of the stewing slag pool 100, and the dust cover 310 can move along the sliding track between the sealing position and the hoisting position. In other embodiments, the dust cover 310 can directly slide along the upper end of the side wall of the stewing slag pool 100. The moving mode of the dust cover 310 is not specifically limited. In the embodiment, when the dust cover 310 is located at the hoisting position, the dust cover 310 is away from the hoisting opening 120 at the upper end of the stewing slag pool 100, and the dust cover 310 does not block the space above the hoisting opening 120 in the vertical direction, so as to facilitate the hoisting of the slag pot 400 into the stewing slag pool 100 from the hoisting opening 120. When the dust cover 310 is located at the sealing position, the dust cover 310 moves above the hoisting opening 120, that is, in the vertical direction, the dust cover 310 completely blocks the hoisting opening 120. In this state, the four edges of the dust cover 310 can be sealed and connected with the upper end of the side wall of the stewing slag pool 100, so as to seal the stewing slag pool 100 and avoid the escape of the smoke. In the embodiment, the dust cover 310 can move along a straight track between the sealing position and the hoisting position. In other embodiments, the moving mode of the dust cover 310 between the sealing position and the hoisting position is not specifically limited.

[0058] In the embodiment, the spraying assembly 320 is arranged at the lower part of the dust cover 310, and is used to spray the stewing slag pool 100. In a specific embodiment, the spraying assembly 320 is a combination of a liquid pipeline and an output port, and the opening direction of the output port is downward. The liquid in the liquid pipeline is sprayed into the stewing slag pool 100 through the output port, and is used to spray and stew the steel slag in the stewing slag pool 100. In other embodiments, the spraying assembly 320 can also be a plurality of liquid pipelines arranged in the horizontal direction at intervals, and a plurality of spraying nozzles are arranged on the liquid pipeline. The liquid in the liquid pipeline can be sprayed downward in the stewing slag pool 100 through the plurality of spraying nozzles, so as to spray and stew the molten slag in the stewing slag pool 100. The plurality of spraying nozzles can realize the liquid spraying effect, improve the spraying coverage of the spraying assembly 320 on the molten slag in the stewing slag pool 100, and improve the stewing effect.

[0059] As Figure 1 and Figure 2As shown in the drawings, in an embodiment, the overturning structure 200 further comprises a rotating assembly 220 and a rotating section 230 connected in transmission, the rotating assembly 220 is located outside the slag pot 100, the rotating section 230 is rotatably arranged in the sidewall of the slag pot 100, one end of the rotating section 230 extending into the inner cavity 110 is connected with the gantry 210, and the rotating section 230 can drive the gantry 210 to overturn by rotating itself.

[0060] The slag pot device with a rotatable slag pot provided by the embodiment provides a specific structure for driving the gantry 210 to overturn, which avoids the damage of the overturning structure 200 caused by being affected by the high temperature of the steel slag due to being located in the slag pot 100.

[0061] In the embodiment, the rotating assembly 220 is a self-rotating assembly. In an embodiment, the rotating assembly 220 is a rotating motor and an output shaft, wherein the output shaft can rotate along its own axis, and in the embodiment, the output shaft is used to connect with the rotating section 230 to drive the rotating section 230 to rotate. In other embodiments, the rotating assembly 220 can also adopt other structures capable of driving the rotating section 230 to rotate, which is not limited in particular. In the embodiment, the rotating section 230 is rotatably arranged in the sidewall of the slag pot 100, one end of the rotating section 230 extending out of the sidewall of the slag pot 100 extends to the outside of the slag pot 100, and is used to connect with the rotating assembly 220, so that the rotating assembly 220 can drive the rotating section 230 to rotate by rotating itself. The other end of the rotating section 230 extends into the slag pot 100 and is connected with the gantry 210, so that the rotating assembly 220 can drive the gantry 210 to overturn downward by the rotating section 230, thereby realizing the pouring of the molten slag.

[0062] As shown in the drawings, Figure 1 and Figure 2 In an embodiment, the gantry 210 comprises a connecting frame 211 and a supporting frame 212, the connecting frame 211 is connected between the rotating section 230 and the supporting frame 212, the supporting frame 212 extends in a direction perpendicular to the rotating axis of the rotating section 230, one end of the supporting frame 212 is detachably connected with the slag pot 400, and the rotating section 230 can drive the supporting frame 212 and the slag pot 400 to overturn around the rotating axis of the rotating section 230 through the connecting frame 211.

[0063] The slag pot device with a rotatable slag pot provided by the embodiment divides the gantry 210 into the connecting frame 211 and the supporting frame 212, and the supporting frame extends in a direction perpendicular to the rotating axis of the rotating section 230, which increases the moment of the rotating section 230 driving the slag pot 400 to overturn, and makes the overturning control of the rotating assembly 220 on the slag pot 400 more accurate and the force applied smaller.

[0064] In particular, in the embodiment, the connecting frame 211 is connected between the rotating section 230 and the supporting frame 212, wherein the rotating axis of the rotating section 230 is the rotating axis of the supporting frame and the rotating axis of the slag pot 400. In a specific embodiment, the end of the rotating section 230 extending into the slag pool 100 is outwardly protruded along the radial direction of the rotating section 230 to form a connecting structure 231, so as to avoid the axis of the connecting frame 211 extending along the rotating axis of the rotating section 230, which results in too small torque of the rotating section 230 to drive the connecting frame 211 to rotate. In the embodiment, the connecting frame 211 extends along the direction parallel to the rotating axis of the rotating section 230, and the supporting frame 212 extends along the direction perpendicular to the rotating axis of the rotating section 230, so that the force angle of the rotating section 230 to drive the connecting frame 211 and the supporting frame 212 of the gantry 210 to rotate is the tangent of the rotating circumferential direction of the rotating section 230, thereby avoiding the generation of other directional components.

[0065] In the embodiment, one end of the connecting frame 211 is connected to the rotating section 230, the other end of the connecting frame 211 is connected to one end of the supporting frame 212, and the other end of the supporting frame 212 is detachably connected to the slag pot 400, so that the slag pot 400 can be hoisted into the supporting frame 212 after being hoisted from the hoisting opening 120, and the slag pot 400 can be hoisted out of the hoisting opening 120 by detaching the connection between the slag pot 400 and the supporting frame 212 after the slag pouring process is completed, for loading the molten slag to be braised next time.

[0066] As shown in FIGS. 1, 2 and 3, the slag braising device 100 comprises a slag pool 100, a hoisting opening 120, a rotating section 230, a connecting frame 211, a supporting frame 212, a slag pot 400, and a turning structure 200. Figure 1 and Figure 2 As shown in FIGS. 1, 2 and 3, the slag braising device 100 comprises a slag pool 100, a hoisting opening 120, a rotating section 230, a connecting frame 211, a supporting frame 212, a slag pot 400, and a turning structure 200.

[0067] The driven section 250 is rotatably arranged in the sidewall of the slag pool 100 along the rotating axis of the rotating section 230, and the driven section 250 is arranged on the opposite sides of the slag pool 100 from the rotating section 230.

[0068] One end of the driven frame 240 is detachably connected to the slag pot 400, the driven frame 240 is arranged on the opposite sides of the slag pot 400 from the supporting frame 212, and the driven frame 240 is connected to the end of the driven section 250 extending into the inner cavity 110.

[0069] The slag braising device with a rotatable slag pot provided by the embodiment can provide symmetrical and balanced support to the opposite sides of the slag pot 400 through the driven frame 240 and the driven section 250, thereby avoiding the instability of the turning and placing of the slag pot 400 caused by the single-sided support of the slag pot 400 by the connecting frame 211 and the supporting frame 212 of the gantry 210.

[0070] Specifically, in one embodiment of this example, the driven section 250 is rotatably inserted into the side wall of the slag-curing tank 100. One end of the driven section 250 extending into the slag-curing tank 100 is connected to one end of the driven frame 240. In this embodiment, the driven section 250 rotates as the rotating assembly 220 drives the slag pot 400 to tilt downwards. In another embodiment, the tilting structure 200 may further include a driven assembly 260, which is a self-rotating component. The rotating assembly 220 consists of a driven rotary motor and a driven output shaft. The driven component 260 is composed of a driven output shaft that can rotate around the axis of the driven section 250. The driven output shaft is connected to one end of the driven section 250 that extends out of the slag-suppressing tank 100 and is used to drive the driven section 250 to rotate. That is, the driven section 250 rotates actively. In other words, the driven section 250 and the rotating section 230 can simultaneously drive the slag pot 400 to flip on opposite sides, thus sharing the force that drives the slag pot 400 to flip, making the force that drives the slag pot 400 to flip more stable, and making the flipping process of the slag pot 400 more stable.

[0071] In this embodiment, a second connecting structure 251 is provided at one end of the driven section 250 that extends into the slag-suppressing tank 100, protruding outward along the radial direction of the driven section 250. This prevents the driven frame 240 from extending along the rotation axis of the driven section 250, which would result in an insufficient torque for the driven section 250 to drive the driven frame 240 to rotate. In this embodiment, the driven frame 240 is divided into two sections. One section of the driven frame 240 extends in a direction parallel to the rotation axis of the driven section 250, and the other section extends in a direction perpendicular to the rotation axis of the driven section 250. This ensures that the angle of force applied when the driven section 250 drives the slag pot 400 to rotate is tangential to the circumferential direction of the driven section 250, thus avoiding the generation of force components in other directions.

[0072] like Figure 1 and Figure 2 As shown, in one specific embodiment, the rotation axis of the driven segment 250 and the rotation axis of the rotating segment 230 are both horizontally arranged and collinear.

[0073] The slag-steaming device for the rotatable slag pot provided in this embodiment sets the rotation axis of the driven section 250 and the rotation axis of the rotating section 230 to be horizontal and collinear, so that the slag pot 400 can be flipped around the horizontal rotation axis, and the slag pot 400 can be tilted evenly when flipping. At the same time, the rotation axis of the driven section 250 and the rotation axis of the rotating section 230 are collinear, that is, the driving section 250 and the rotating section 230 have the same supporting force on the flipping of the slag pot 400.

[0074] Specifically in the embodiment, the other segment of the driven frame 240 is arranged to extend in a direction perpendicular to the rotation axis of the driven segment 250, and the support frame 212 is arranged to extend in a direction perpendicular to the rotation axis of the rotation segment 230, that is, the extending axis of the other segment of the driven frame 240 is arranged in parallel with the extending axis of the support frame 212, so that the support force of the driven frame 240 and the support frame 212 on the opposite sides of the slag ladle 400 is the same.

[0075] As shown in Figure 1 and Figure 2 In a specific embodiment, the dust removal structure 300 further comprises a dust removal pipeline 330 for absorbing smoke and dust, at least one dust suction port 331 of the dust removal pipeline 330 is arranged on the inner side wall of the dust removal cover 310, and at least one dust suction port 331 is arranged on the upper inner side wall of the slag holding pit 100.

[0076] The slag holding device with a rotatable slag ladle provided by the embodiment can be used to absorb the smoke generated in the slag holding pit 100 during the hot splashing operation and the slag holding operation due to the spraying of molten slag, so as to avoid the escape of toxic smoke from the slag holding pit 100.

[0077] Specifically in the embodiment, the dust removal pipeline 330 uses a blower to draw air from the outside of the slag holding pit 100. In the embodiment, at least one dust suction port 331 is arranged on the inner side wall of the dust removal cover 310, that is, the dust removal pipeline 330 is connected with the dust removal cover 310, and the dust suction port 331 arranged on the inner side wall of the dust removal cover 310 can absorb the smoke that drifts upward in the slag holding pit 100. At least one dust suction port 331 is arranged on the upper inner side wall of the slag holding pit 100, that is, the dust removal pipeline 330 is also connected with the side wall of the slag holding pit 100, and the dust suction port 331 arranged on the upper inner side wall of the slag holding pit 100 can absorb the smoke that drifts upward and then settles down or part of the smoke that is too heavy to float upward, so as to achieve a dust suction range with a higher coverage degree.

[0078] As shown in Figure 1 and Figure 3 In a specific embodiment, the side wall of the slag holding pit 100 is composed of a wall layer 130 and a heat insulation layer 140, the heat insulation layer 140 is located on the inner side of the wall layer 130, and the heat insulation layer 140 is connected to the inner side wall of the wall layer 130 through a connecting piece.

[0079] The slag stewing device of the rotatable slag tank provided by the embodiment has a side wall of the slag stewing pool 100 composed of a wall layer 130 and a heat insulation layer 140, so that good heat insulation efficiency is achieved. Since the molten slag is a high-temperature solid-liquid mixture, the temperature thereof is high, and the side wall of the single-layer slag stewing pool 100 is easily affected by the temperature, so that the side wall of the slag stewing pool 100 is eroded by the molten slag. Therefore, the wall layer 130 and the heat insulation layer 140 are arranged, so that the stability and service life of the wall are effectively improved.

[0080] In the embodiment, the wall layer 130 is vertically arranged along the circumference of the slag stewing pool 100, so that the wall layer 130 can surround the inner cavity 110 of the slag stewing pool 100. The heat insulation layer 140 is also arranged along the circumference of the slag stewing pool 100, so that the heat insulation layer 140 can protect the wall layer 130 from high-temperature erosion of the molten slag. In the embodiment, the heat insulation layer 140 can be hung on the wall layer 130 after being anchored by through bolts. In other embodiments, the heat insulation layer 140 can also be connected by other connection modes, which are not limited in particular.

[0081] As shown in FIGS. 1 and 2, Figure 1 and Figure 3 in a specific embodiment, the wall layer 130 is composed of concrete, and the heat insulation layer 140 is formed by a steel plate or a cast iron plate.

[0082] The slag stewing device of the rotatable slag tank provided by the embodiment has a heat insulation layer 140 composed of a steel plate or a cast iron plate, which can significantly improve the heat bearing capacity of the wall layer 130. Since the thermal conductivity of the steel material and the iron material is better than that of the concrete, the heat can be quickly transferred and dissipated, so that the wall layer 130 composed of the concrete is not continuously affected by high temperature.

[0083] In a specific embodiment, the heat insulation layer 140 is formed by connecting a plurality of steel plates along the circumference of the slag stewing pool 100. The plurality of steel plates of the heat insulation layer 140 are hung on the concrete of the wall layer 130 after being anchored by through bolts.

[0084] As shown in FIGS. 1 and 2, Figure 1 and Figure 3 in a specific embodiment, the bottom wall of the slag stewing pool 100 is composed of a soil layer 150 and a drainage layer 160. The drainage layer 160 is arranged above the soil layer 150, and the drainage layer 160 is formed by laying a steel blank.

[0085] The slag stewing device of the rotatable slag tank provided by the embodiment is also provided with a two-layer structure at the bottom wall of the slag stewing pool 100, so that good heat insulation efficiency is achieved. Since the molten slag is a high-temperature solid-liquid mixture, the temperature is high, the heat capacity of the single-layer earth layer is high, heat dissipation is difficult, the bottom earth of the slag stewing pool 100 is eroded by the molten slag, and the bottom earth continuously stores heat and is not easy to dissipate, so that the operator needs to wait for a long time before entering the slag stewing pool 100 for processing. Therefore, the arrangement of the earth layer 150 and the drainage layer 160 made of steel billets can effectively improve the stability and service life of the earth layer 150, and also avoid the problem of low slag cleaning efficiency of the construction personnel caused by slow heat dissipation of the earth layer 150.

[0086] In particular, in the embodiment, the earth layer can be composed of concrete, and in other embodiments, the earth layer can also be composed of other stable soil structures, without specific limitation. In the embodiment, the drainage layer 160 is laid on the surface of the earth layer using steel billets. The steel material has good heat conductivity, can quickly conduct the heat of the molten slag after hot stewing by spraying, and avoid heat accumulation. At the same time, the steel drainage layer 160 can also avoid the liquid sprayed by the spraying assembly 320 being absorbed by the earth layer, causing the earth layer to be wet and sticky, and resulting in low efficiency in cleaning the molten slag.

[0087] As shown in Figure 1 and Figure 3 In a specific embodiment, a slag removal opening 170 for the entry and exit of a shovel truck is arranged on the side wall of the bottom of the slag stewing pool 100, and a closable roller shutter door 180 is arranged at the slag removal opening 170 to open or close the slag removal opening 170. A water cooling structure is arranged in the roller shutter door 180.

[0088] The slag stewing device of the rotatable slag tank provided by the embodiment is also provided with a two-layer structure at the bottom wall of the slag stewing pool 100, so that good heat insulation efficiency is achieved. Since the molten slag is a high-temperature solid-liquid mixture, the temperature is high, the heat capacity of the single-layer earth layer is high, heat dissipation is difficult, the bottom earth of the slag stewing pool 100 is eroded by the molten slag, and the bottom earth continuously stores heat and is not easy to dissipate, so that the operator needs to wait for a long time before entering the slag stewing pool 100 for processing. Therefore, the arrangement of the earth layer 150 and the drainage layer 160 made of steel billets can effectively improve the stability and service life of the earth layer 150, and also avoid the problem of low slag cleaning efficiency of the construction personnel caused by slow heat dissipation of the earth layer 150.

[0089] In the embodiment, a water cooling structure is arranged in the roller shutter door 180 to resist the high-temperature corrosion of the molten slag in the slag stewing pool 100, quickly take away the heat absorbed by the roller shutter door 180 close to the molten slag, and avoid the problem of reduced service life of the roller shutter door 180 caused by long-term heat radiation.

[0090] As shown in Figure 2 and Figure 3 Figure 2 Figure 3As shown, in a specific embodiment, the sidewall of the bottom of the residue retorting pool 100 is also provided with a drainage port 190, which is arranged on the opposite side of the residue retorting pool 100 from the residue scraping port 170, and the bottom wall of the residue retorting pool 100 is arranged to be downwardly inclined from the residue scraping port 170 to the drainage port 190.

[0091] The residue retorting device of the rotatable residue tank provided by the present embodiment can make the liquid sprayed by the spraying assembly 320 flow out of the drainage port 190 along the inclination angle of the bottom wall of the residue retorting pool 100 when the liquid flows on the bottom of the residue retorting pool 100, thereby avoiding the accumulation of the liquid sprayed by the spraying assembly 320 on the bottom of the residue retorting pool 100 and the generation of water accumulation.

[0092] In a specific embodiment, the specific implementation workflow of the residue retorting device of the rotatable residue tank is as follows:

[0093] (1) The dust removal cover 310 is moved from the cover setting position to the lifting position, so that the lifting port is not blocked in the height direction, the crane lifts the residue tank 400 onto the gantry 210, the dust removal cover 310 is moved from the lifting position to the cover setting position, and the periphery of the dust removal cover 310 is sealingly connected to the upper end of the sidewall of the residue retorting pool 100, so that the dust removal cover 310 sealingly covers the lifting port 120;

[0094] (2) The rotating assembly 220 rotates the gantry 210 and the residue tank 400 by 180° through the rotating section 230, and the liquid molten slag is poured into the bottom of the residue retorting pool 100;

[0095] (3) At the same time of pouring, the dust removal pipeline 330 of the dust removal structure 300 starts to remove and absorb the flue gas;

[0096] (4) After the pouring of the liquid molten slag is completed, the spraying assembly 320 below the dust removal cover 310 sprays water on the molten slag to cool and granulate and crack the molten slag;

[0097] (5) After there is no smoke and flue gas, the dust removal cover 310 is moved from the cover setting position to the lifting position, the crane lifts the residue tank 400 away from the gantry 210, and then the dust removal cover 310 is moved from the lifting position to the cover setting position, and the dust removal cover 310 sealingly covers the lifting port 120 again;

[0098] (6) After the molten slag is granulated and cracked and cooled, the rolling shutter door 180 of the residue scraping port 170 is opened, and the scraper enters the bottom of the residue retorting pool 100 to scrape away the granulated and cracked residue particles;

[0099] (7) The remaining cooling water generated by the spraying assembly 320 is drained from the drainage port 190 below the residue retorting pool 100.

[0100] (8) After the above operations are completed, the next cycle operation can be performed.
