Drive the transverse vehicle of the steel slag crushing device to reciprocate horizontally through the transverse driving member of the steel slag crushing device to drive the breaker, the stirring plow, and the slag pushing plate of the steel slag crushing device to reciprocate horizontally. Among them, the slag pushing plate reciprocates horizontally at a high position along with the transverse vehicle;

At the same time, it should be noted that the terms "first", "second", etc. in the specification, claims and the above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here.

[0031] An embodiment of the present invention provides a steel slag crushing device, which includes a crushing mechanism 1, a stirring mechanism 2, a slag pushing mechanism 3, a steel slag box 4 and a transverse movement driving assembly 5; the crushing mechanism 1 includes a crushing hammer 12 and a first driving assembly 11, the lower end of the crushing hammer 12 is arranged towards the inner bottom wall of the steel slag box 4, and the first driving assembly 11 is used to drive the crushing hammer 12 to move vertically in a reciprocating manner; the stirring mechanism 2 includes a stirring plow 21 and a second driving assembly 22, and the second driving assembly 22 is used to drive the stirring plow 21 to move vertically; the slag pushing mechanism 3 includes a third driving assembly 31 and a slag pushing plate 32, the lower end of the slag pushing plate 32 is arranged towards the inner bottom wall of the steel slag box 4, and the third driving assembly 31 is used to drive the slag pushing plate 32 to move vertically; the steel slag box 4 is provided with a slag outlet 41, and the slag pushing plate 32 is used to discharge qualified steel slag from the slag outlet 41; the transverse movement driving assembly 5 includes a transverse movement vehicle 51 and a transverse movement driving member 52, the crushing mechanism 1, the stirring mechanism 2 and the slag pushing mechanism 3 are arranged on the transverse movement vehicle 51, the transverse movement vehicle 51 is slidably connected to the steel slag box 4 in the transverse direction, and the transverse movement driving member 52 is used to drive the transverse movement vehicle 51 to move horizontally.

[0032] Specifically, as shown in Figures 1 to 5 the steel slag box 4 is a box structure with an opening at the top, a slag outlet 41 is provided at the inner bottom wall near the left end, the transverse movement driving member 52 can be a common driving mechanism such as a motor to realize the horizontal driving of the transverse movement vehicle 51, the cross-section of the transverse movement vehicle 51 in the ZY plane in the figure is a structure similar to a U shape, the crushing mechanism 1, the stirring mechanism 2 and the slag pushing mechanism 3 are located at the middle position of this U-shaped structure, the transverse movement vehicle 51 is provided with a through-hole structure so that the crushing hammer 12, the stirring plow 21 and the slag pushing plate 32 can extend into the steel slag box 4 or retract into this through-hole structure (slider and slide rail structures can be set to realize the vertical sliding connection between the crushing hammer 12, the stirring plow 21, the slag pushing plate 32 and the transverse movement vehicle 51), by driving the transverse movement vehicle 51 to move horizontally (i.e., the positive and negative directions of the X-axis in the figure) by the transverse movement driving member 52, the crushing mechanism 1, the stirring mechanism 2 and the slag pushing mechanism 3 can be driven to move horizontally at the same time.

[0033] Exemplarily, a plurality of protrusions can be arranged on the lower end surface of the breaker 12 to improve the crushing effect on the steel slag (the protrusions are not shown in the figure); the stirring plow 21 can adopt a structure similar to the common plow in life, as long as it can plow the steel slag to be processed, break it and pick out large pieces of steel slag that are not easily broken; combined with Figure 1 and Figure 5 As shown, the slag pushing plate 32 is a plate-like structure parallel to the ZY plane in the figure. When the third driving assembly 31 drives the slag pushing plate 32 to move vertically to a certain height, and then drives the slag pushing plate 32 to move horizontally through the transverse movement driving assembly 5, the steel slag can be pushed to move in the steel slag box 4.

[0034] It should be noted that the specific structures of the breaker 12, the seat body 211, the plow teeth 212 and the slag pushing plate 32 can be designed according to needs. For example, the specific surface texture of the breaker 12, the specific structure of the stirring plow 21 and the specific plate surface structure of the slag pushing plate 32, etc., are not specifically limited here; in addition, the first driving assembly 11, the second driving assembly 22 and the third driving assembly 31 can be designed according to needs. For example, an air cylinder is used, as long as it can drive the breaker 12, the stirring plow 21 and the slag pushing plate 32 to move vertically relative to the transverse moving vehicle 51 respectively, which is not specifically limited here.

[0035] The steel slag crushing device of the present invention sets the crushing mechanism 1, the stirring mechanism 2 and the slag pushing mechanism 3 on the transverse moving vehicle 51, and the transverse moving vehicle 51 is slidably connected to the steel slag box 4. At the same time, the transverse driving is performed by the transverse driving member 52, and the first driving assembly 11, the second driving assembly 22 and the third driving assembly 31 respectively perform vertical driving on the breaker 12, the stirring plow 21 and the slag pushing plate 32, so that the breaker 12 can perform vertical reciprocating hammering actions on the steel slag to be processed at different transverse positions in the steel slag box 4 to achieve the hammering crushing of the steel slag. Moreover, by moving the stirring plow 21 vertically to a certain height and plowing the steel slag to be processed horizontally, the stirring and crushing of the steel slag can be realized. In this way, through plowing and stirring, on the one hand, part of the steel slag to be processed is broken, and on the other hand, large pieces of steel slag to be processed can be picked out and broken again. After repeated operations until qualified steel slag is obtained (that is, solid granular steel slag that meets the requirements of the slag smothering process), at this time, by making the slag pushing plate 32 move vertically to a certain height and pushing the qualified steel slag horizontally to the slag outlet 41 for discharging, the functions of hammering and crushing the steel slag to be processed, stirring and crushing the steel slag to be processed, and pushing the qualified steel slag are realized. By controlling the steel slag crushing device to achieve the above functions, compared with the traditional roller-type steel slag crushing device, this solution can obtain qualified steel slag with more uniform crushing and better quality, which better meets the requirements of the slag smothering process and realizes the environmental protection treatment of steel slag; in addition, the steel slag crushing device has complete functions and can adapt to the crushing treatment of steel slag of different sizes through multiple hammering and crushing and stirring and crushing, and has good versatility.

[0036] Optionally, the stirring plow 21 includes a seat body 211 and plow teeth 212. At least two of the plow teeth 212 are arranged at intervals along the longitudinal direction on the seat body 211, and the lower ends of the plow teeth 212 are arranged towards the inner bottom wall of the steel slag box 4.

[0037] Specifically, as shown in Figure 4 FIG. [6], the plow teeth 212 of the stirring plow 21 are columnar structures, one end of which is conical, and the other end is integrally connected to the seat body 211. By designing the gap size between two adjacent plow teeth 212, the size of the steel slag that can pass through the gap can be adjusted. Further, as shown in Figure 1 FIG. [8], nine plow teeth 212 are arranged at intervals in the longitudinal direction (i.e., the positive and negative directions of the Y-axis in the figure) as a group, and two groups are arranged at intervals in the transverse direction (i.e., the positive and negative directions of the X-axis in the figure), thereby achieving a better stirring effect.

[0038] In this way, the steel slag to be processed is broken by the plowing of the plow teeth 212. The steel slag to be processed that meets the size requirements can pass through the intervals between the plow teeth 212, while the large pieces of steel slag to be processed that do not meet the size requirements are pushed by the stirring plow 21. In this way, the large pieces of steel slag to be processed are concentrated together and can be broken again by the crushing mechanism 1, so as to obtain more uniform steel slag and improve the quality of the steel slag crushing process.

[0039] Optionally, wheels 514 are provided on the transverse moving vehicle 51, and rails 43 arranged in the transverse direction are provided on the steel slag box 4. The transverse moving vehicle 51 is slidably connected to the rails 43 through the wheels 514.

[0040] Specifically, as shown in Figures 1 to 5 FIG.

[19] , a total of eight wheels 514 are provided on both sides of the transverse moving vehicle 51 in the longitudinal direction (i.e., the positive and negative directions of the Y-axis in the figure). The position and quantity of the wheels 514 can be designed according to actual needs.

[0041] In this way, the transverse moving vehicle 51 is slidably connected to the steel slag box 4 through the wheels 514 and the rails 43, facilitating the transverse movement of the transverse moving vehicle 51.

[0042] Optionally, wheel baffles 42 are provided on the steel slag box 4. The wheel baffles 42 are arranged parallel to the rails 43 and are located above the rails 43. The wheels 514 are located between the rails 43 and the wheel baffles 42.

[0043] Specifically, as shown in Figure 5 FIG.

[30] , the lower end plane of the wheel baffle 42 is parallel to the plane where the rails 43 are located. The wheel baffle 42 is located above the rails 43 and the wheels 514 and is installed on the steel slag box 4 through screw fasteners.

[0044] In this way, the wheel baffle 42 can, to a certain extent, prevent the side shift vehicle 51 from tipping over, improving the reliability of the steel slag crushing device.

[0045] Optionally, the side shift vehicle 51 is provided with a first guiding groove 511, a second guiding groove 512, and a third guiding groove 513 that are vertically arranged. The crushing hammer 12 is slidably connected to the first guiding groove 511, the stirring plow 21 is slidably connected to the second guiding groove 512, and the slag pushing plate 32 is slidably connected to the third guiding groove 513.

[0046] Specifically, in combination with Figure 1 As shown, the first guiding groove 511, the second guiding groove 512, and the third guiding groove 513 provided on the side shift vehicle 51 are all vertically arranged (i.e., the center line of the groove is arranged along the Z axis in the figure). The crushing hammer 12, the stirring plow 21, and the slag pushing plate 32 are slidably connected to the side shift vehicle 51 at the first guiding groove 511, the second guiding groove 512, and the third guiding groove 513 respectively.

[0047] In this way, the crushing hammer 12, the stirring plow 21, and the slag pushing plate 32 can be guided by the first guiding groove 511, the second guiding groove 512, and the third guiding groove 513 to move vertically, avoiding the vertical movement of the crushing hammer 12, the stirring plow 21, and the slag pushing plate 32 from being skewed.

[0048] Optionally, the crushing hammer 12 includes a first crushing hammer 121 and a second crushing hammer 122. The first driving assembly 11 includes a first driving member 111 and a second driving member 112. The first driving member 111 and the second driving member 112 are respectively used to drive the first crushing hammer 121 and the second crushing hammer 122 to reciprocate vertically. The lower ends of the first crushing hammer 121 and the second crushing hammer 122 are respectively provided with a first blade structure 1211 and a second blade structure 1221. The first blade structure 1211 is arranged horizontally, and the second blade structure 1221 is arranged longitudinally.

[0049] Specifically, in combination with Figures 1 to 3 As shown, the lower ends of the first crushing hammer 121 and the second crushing hammer 122 are respectively provided with a first blade structure 1211 arranged horizontally (i.e., in the positive and negative directions of the X axis in the figure) and a second blade structure 1221 arranged longitudinally (i.e., in the positive and negative directions of the Y axis in the figure). The first crushing hammer 121, the second crushing hammer 122, the stirring plow 21, and the slag pushing plate 32 are sequentially slidably connected to the side shift vehicle 51 vertically (i.e., in the positive and negative directions of the Z axis in the figure).

[0050] In this way, the first breaker 121 and the second breaker 122 respectively form a knife-hammer-like structure arranged transversely and longitudinally (i.e., one end of the hammer body is a flat blade structure). To meet the requirements of the slag smothering process, the steel slag to be processed is in a molten state. By controlling the vertical reciprocating movement of the first breaker 121 and the second breaker 122 in cooperation, the molten and viscous steel slag to be processed can be hammered into blocks transversely and longitudinally, making the steel slag crushing device more suitable for the crushing treatment of molten steel slag.

[0051] Optionally, it further includes a cooling device which is installed on the transverse movement driving assembly 5 and is used to spray coolant onto the breaker 12 and the stirring plow 21.

[0052] In this way, the cooling device can be a nozzle or the like, and it cools by spraying coolant (such as water) onto the breaker 12 and the stirring plow 21. By controlling parameters such as the temperature of the coolant, the crushing treatment of steel slag at different temperatures can be achieved; in addition, the cooling device can also cool the steel slag, making the molten steel slag gradually form solid granular steel slag, and finally obtaining qualified steel slag.

[0053] Optionally, a gear 515 is provided on the transverse movement vehicle 51, a rack 44 arranged transversely is provided on the steel slag box 4, the gear 515 meshes with the rack 44, and the transverse movement driving member 52 is drivingly connected to the gear 515.

[0054] Specifically, as shown in Figures 1 to 5 Connecting brackets (which can be specifically designed according to the structure to be carried) are provided on both sides of the transverse movement vehicle 51 in the longitudinal direction (i.e., the positive and negative directions of the Y-axis in the figure). A gear 515 is provided on the end face of the connecting bracket facing the steel slag box 4, a rack 44 parallel to the track 43 is provided on the steel slag box 4, and the transverse movement driving member 52 is a common power transmission component such as a motor and a reducer.

[0055] In this way, by driving the gear 515 to rotate through the transverse movement driving member 52, the gear 515 meshes with the rack 44, thereby driving the transverse movement vehicle 51 to move transversely.

[0056] Optionally, the first driving assembly 11 further includes a first crank-slider mechanism 113 and a second crank-slider mechanism 114. The first driving member 111 is drivingly connected to the crank of the first crank-slider mechanism 113, and the second driving member 112 is drivingly connected to the crank of the second crank-slider mechanism 114. The sliders of the first crank-slider mechanism 113 and the second crank-slider mechanism 114 are respectively connected to the first breaker 121 and the second breaker 122. The second driving assembly 22 includes a third crank-slider mechanism 221 and a third driving member 222. The third driving assembly 31 includes a fourth crank-slider mechanism 311 and a fourth driving member 312. The third driving member 222 and the fourth driving member 312 are respectively drivingly connected to the cranks of the third crank-slider mechanism 221 and the fourth crank-slider mechanism 311. The sliders of the third crank-slider mechanism 221 and the fourth crank-slider mechanism 311 are respectively connected to the mixing plow 21 and the slag pushing plate 32.

[0057] Specifically, as shown in Figures 1 to 5 , the first driving member 111, the second driving member 112, the third driving member 222, and the fourth driving member 312 respectively drive the cranks of the first crank-slider mechanism 113, the second crank-slider mechanism 114, the third crank-slider mechanism 221, and the fourth crank-slider mechanism 311 to rotate through transmission structures such as speed reducers. The crank drives the slider through a connecting rod (the breakers 12, the mixing plow 21, and the slag pushing plate 32 are equivalent to sliders, and corresponding slider structures can also be designed according to needs), so that the slider moves vertically relative to the traversing vehicle 51 (equivalent to the frame in the crank-slider mechanism). The first driving member 111, the second driving member 112, the third driving member 222, the fourth driving member 312, the corresponding four speed reducers, and corresponding bearing seats and other structures are all installed on the connecting bracket of the traversing vehicle 51 through fasteners.

[0058] In this way, the reciprocating vertical movements of the first breaker 121, the second breaker 122, the mixing plow 21, and the slag pushing plate 32 can be realized through the first crank-slider mechanism 113, the second crank-slider mechanism 114, the third crank-slider mechanism 221, and the fourth crank-slider mechanism 311. The structure is simple and it is convenient for the first breaker 121 and the second breaker 122 to hammer and break the steel slag to be processed.

[0059] The present invention also provides a method for crushing steel slag, which uses the steel slag crushing device as described above, and includes the following steps:

[0060] S1. Pour the steel slag to be processed into the steel slag box 4 of the steel slag crushing device;

[0061] S2. Drive the traversing vehicle 51 of the steel slag crushing device to reciprocate horizontally through the traversing drive member 52 of the steel slag crushing device, so as to drive the crushing hammer 12, the stirring plow 21 and the slag pushing plate 32 of the steel slag crushing device to reciprocate horizontally. Among them, the slag pushing plate 32 reciprocates horizontally with the traversing vehicle 51 at a high position;

[0062] S3. While the crushing hammer 12 reciprocates horizontally with the traversing vehicle 51, drive the crushing hammer 12 to reciprocate vertically through the first drive assembly 11 of the steel slag crushing device, so as to crush the steel slag to be processed;

[0063] S4. While the stirring plow 21 reciprocates horizontally with the traversing vehicle 51, drive the stirring plow 21 to descend a preset distance through the second drive assembly 22 of the steel slag crushing device, so as to plow the steel slag to be processed, pick out large pieces of the steel slag to be processed, and level the steel slag to be processed;

[0064] S5. When the steel slag to be processed is processed into qualified steel slag, drive the slag pushing plate 32 to descend to a low position through the third drive assembly 31 of the steel slag crushing device while the slag pushing plate 32 reciprocates horizontally with the traversing vehicle 51, so as to push the qualified steel slag to the slag outlet 41 of the steel slag box 4 for discharging.

[0065] Specifically, in combination with Figure 1As shown, the breaker 12, the stirring plow 21, and the slag pushing plate 32 are at a high position at this time. In step S1, the steel slag to be processed can be poured into the steel slag box 4 by, for example, a crane; in step S2, the traversing vehicle 51 is driven to drive the crushing mechanism 1, the stirring mechanism 2, and the slag pushing mechanism 3 to move horizontally back and forth together; step S3 is carried out simultaneously with step S2. In step S3, the breaker 12 is driven to move vertically back and forth (that is, the breaker 12 is driven to move vertically repeatedly between the low position and the high position) to achieve the hammering action. And by simultaneously carrying out step S2, the traversing vehicle 51 drives the breaker to move horizontally back and forth, so that the breaker 12 can hammer and crush all the steel slag to be processed in the steel slag box 4. After completion, the breaker 12 is driven to rise to the high position; step S4 can be carried out simultaneously with steps S3 and S2 (that is, while the breaker 12 is hammering, the stirring plow 21 also plows the hammered steel slag along with the traversing vehicle 51 to achieve the effect of removing large pieces of steel slag and leveling), or step S4 can also be carried out simultaneously with step S2 after step S3 is completed. By driving the stirring plow 21 to descend a preset distance (usually the plow teeth 212 of the stirring plow 21 extend into the steel slag to be processed to a certain depth, and the stirring plow 21 still has a certain distance from the low position) and keeping it unchanged, and then driving the traversing vehicle 51 to move horizontally, the stirring plow 21 stirs and crushes the steel slag to be processed, removes large pieces of the steel slag to be processed, and levels the steel slag to be processed. (To obtain qualified steel slag with better quality, the stirring plow 21 can be driven to descend a certain distance again, and the traversing vehicle 51 is driven to move horizontally again. By repeating the above operations until the stirring plow 21 gradually descends to the low position, the final qualified steel slag is more uniform), and then the stirring plow 21 is driven to return to the high position; step S5 can be carried out simultaneously with step S2, and needs to be carried out after steps S3 and S4 are completed. First, the slag pushing plate 32 is driven to descend from the high position to the low position, then the traversing vehicle 51 is driven to move in the reverse direction of the X axis in the figure to push the qualified steel slag to the slag outlet 41, and finally the slag pushing plate 32 is driven to return to the high position.

[0066] It should be noted that the high positions and low positions of the breaker 12, the stirring plow 21, and the slag pushing plate 32 are usually formed by the stroke limits of the first driving assembly 11, the second driving assembly 22, and the third driving assembly 31, that is, the highest positions and the lowest positions that the breaker 12, the stirring plow 21, and the slag pushing plate 32 can reach. However, in order to avoid the breaker 12, the stirring plow 21, and the slag pushing plate 32 from impacting the inner bottom wall of the steel slag box 4 when descending, the low positions of the breaker 12, the stirring plow 21, and the slag pushing plate 32 are usually spaced a certain distance above the inner bottom wall of the steel slag box 4. In this way, a part of the fine steel slag powder is located on the inner bottom wall of the steel slag box 4 to play a buffering role. It can be understood that the user can also design the specific positions of the high positions and the low positions according to actual needs; in addition, the preset distance of the stirring plow 21 can also be designed according to parameters such as the weight and volume of the steel slag to be processed, and no specific restrictions are made here.

[0067] The steel slag crushing method of the present invention drives the traversing vehicle 51 of the steel slag crushing device to drive the crushing mechanism 1, the stirring mechanism 2 and the slag pushing mechanism 3 to move horizontally back and forth, and drives the crushing hammer 12, the stirring plow 21 and the slag pushing plate 32 to move vertically back and forth, so as to successively realize the functions of hammering and crushing the steel slag to be treated, stirring and crushing (and removing large pieces of the steel slag to be treated to repeat the hammering and crushing and stirring and crushing), and pushing the qualified steel slag to the slag outlet 41. More uniform qualified steel slag can be obtained, the quality of steel slag crushing treatment is improved, and the requirements of the slag smothering process and environmental protection treatment are met.

[0068] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Without departing from the spirit and scope of the present disclosure, those skilled in the art can make various changes and modifications, and these changes and modifications will all fall within the protection scope of the present invention.
