Description

Technical Field

[0001] The present invention relates to the technical field of steel slag dust treatment, and particularly relates to a dust removal mechanism for a slag box. Background Art

[0002] In industries such as iron and steel, metallurgy, etc., it is usually necessary to use a slag box to collect and temporarily store the steel slag (such as desulfurization slag, casting residue, ladle bottom slag, etc.) generated during the steel smelting process for subsequent treatment.

[0003] The existing slag box is a semi-open slag box, and a cover body is only provided on one side above the main body of the slag box, and the other side is an open structure. With such a structural design, during the slag dumping operation and the water spraying and cooling process, due to the large number of open areas, dust is easily scattered from the openings, resulting in unorganized emissions, polluting the environment and affecting the operation safety; moreover, the dust removal pipeline of the existing slag box is arranged on the back of the main body of the slag box, and since the dust will spread upward during the dumping of steel slag, such a structural design will lead to low dust suction efficiency. Summary of the Invention

[0004] Aiming at the above deficiencies existing in the prior art, the purpose of the present invention is to provide a dust removal mechanism for a slag box to solve the problems of low dust suction efficiency of the existing dust removal mechanism for a slag box and unorganized emission of dust caused by the incomplete closure of the structure.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A dust removal mechanism for a slag box includes a cover body covering the top of the main body of the slag box. The cover body is composed of a fixed top cover and a movable top cover. The lower edge of the fixed top cover is fixed to the upper edge of the main body of the slag box, and an opening convenient for slag dumping operation is formed between the two; a dust removal pipeline is arranged on the top of the fixed top cover; the movable top cover is rotatably connected to the fixed top cover through a hinge mechanism; the movable top cover is connected to a driving mechanism, and the driving mechanism can drive the movable top cover to perform a rotational opening and closing movement relative to the fixed top cover to close or open the opening.

[0006] Further, the fixed top cover is composed of a fixed rectangular plate and lateral baffle plates located at both ends of the fixed rectangular plate. One long side of the fixed rectangular plate is fixed to one long side of the upper edge of the main body of the slag box, and the two lateral baffle plates are respectively fixedly installed at the ends where the short sides of the fixed rectangular plate and the upper edge of the main body of the slag box are located; the movable top cover is a rectangular plate, and the movable top cover is rotatably connected to the other long side of the fixed rectangular plate through one long side, and the other long side of the movable top cover overlaps on the other long side of the upper edge of the main body of the slag box to close the opening; in the overlapping state, the movable top cover and the fixed rectangular plate form an inverted V shape.

[0007] Further, the driving mechanism is connected to the movable top cover through a flexible traction assembly.

[0008] Furthermore, the flexible traction assembly includes two traction steel wires. One end of each of the two traction steel wires is fixed to the upper surface of the movable top cover. The connection line of the fixing points of the two traction steel wires on the upper surface of the movable top cover is parallel to the axis direction of the hinge mechanism and is symmetrically arranged left and right. The other end winds around its respective guiding assembly and is connected to the winch of the corresponding driving mechanism.

[0009] Furthermore, a support frame is provided on the fixed top cover. The support frame includes four vertically arranged support legs and several support rods fixedly connected to the upper surface of the support legs. The lower ends of two of the support legs are fixed to the upper surface of the fixed top cover, and the connection line of the two fixed points is parallel to the axis direction of the hinge mechanism. The lower ends of the other two support legs are fixed to the ground area directly opposite to the middle of the rear side bottom edge line of the slag box. The driving mechanism is arranged on the ground and is located between the two support legs; two sets of guiding assemblies are symmetrically installed on the opposite sides of the upper surface of the support rods; Each set of guiding assemblies includes four steering wheels distributed in a rectangle. Among them: the first steering wheel and the second steering wheel are arranged along a diagonal line of the rectangle where they are located, and their rotating shafts are parallel to the upper surface of the support rod; the third steering wheel and the fourth steering wheel are arranged along the other diagonal line of the rectangle where they are located, and their rotating shafts are perpendicular to the upper surface of the support rod; one end of each of the two traction steel wires is fixed to the movable top cover, and the other end sequentially winds around the first steering wheel, the third steering wheel, the fourth steering wheel, and the second steering wheel of the corresponding side guiding assembly, and then the two traction steel wires are bundled to the winch of the corresponding driving mechanism.

[0010] Furthermore, a limit sensor is provided on the driving mechanism. The length of the wire rewinding is monitored through the limit sensor. When the length of the wire rewinding reaches the set value, the driving mechanism is triggered to stop working.

[0011] Furthermore, a plurality of limit rods are vertically arranged at intervals near the edge of the top of the fixed top cover close to the hinge mechanism.

[0012] Furthermore, the hinge mechanism is a hinge shaft or a plurality of hinge hinges arranged at intervals.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. For the slag box dust removal mechanism provided by the present invention, by arranging the dust removal pipeline on the top of the slag box, dust can be directly sucked from above the slag box, so as to maximize the suction of dust into the dust removal device, enhance the dust removal effect, and reduce the possibility of dust escaping. At the same time, in cooperation with the flipable protective cover, the present invention can be closed during the slag dumping operation and the water spraying and cooling process, avoiding the dust escaping during the operation due to too many open areas of the slag box, and converting the dust from unorganized emission to organized emission.

[0014] 2. Through the collaborative action of electromechanical components such as motors, speed reducers, and hoisting wheels, the present invention realizes the automatic opening and closing function of the top cover, further reducing the need for manual intervention and enhancing the operation safety and dust removal stability.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The following further describes the detailed implementation manners of the present invention with reference to the drawings. Embodiment

[0017] See Figure 1 , Figure 2 , the present invention provides a slag box dust removal mechanism, including a cover body 2 covering the top of the slag box main body 1. The cover body 2 is composed of a fixed top cover 201 and a movable top cover 202. The lower edge of the fixed top cover 201 is fixed to the upper edge of the slag box main body 1, and an opening convenient for slag dumping operation is formed therebetween; a dust removal pipe 5 is provided on the top of the fixed top cover 201; the movable top cover 202 is rotatably connected to the fixed top cover 201 through a hinged mechanism 3; the movable top cover 202 is connected to a driving mechanism 6, and the driving mechanism 6 can drive the movable top cover 202 to rotate and open or close relative to the fixed top cover 201 to close or open the opening.

[0018] Specifically, the fixed top cover 201 is composed of a fixed rectangular plate and lateral baffle plates located at both ends of the fixed rectangular plate. One long side of the fixed rectangular plate is fixed to one long side of the edge of the slag box main body 1, and the two lateral baffle plates are respectively fixedly installed at the ends where the short sides of the fixed rectangular plate and the edge of the slag box main body 1 are located; the movable top cover 202 is a rectangular plate, and the movable top cover 202 is rotatably connected to the other long side of the fixed rectangular plate through one long side, and the other long side of the movable top cover 202 overlaps on the other long side of the edge of the slag box main body 1 to close the opening; in the overlapping state, the movable top cover 202 and the fixed rectangular plate form an inverted V shape.

[0019] Specifically, the driving mechanism 6 is connected to the movable top cover 202 through a flexible traction assembly.

[0020] During specific implementation, the flexible traction assembly includes two traction steel wires 7. One end of each of the two traction steel wires 7 is fixed to the upper surface of the movable top cover 202. The connection line of the fixing points of the two traction steel wires 7 on the upper surface of the movable top cover 202 is parallel to the axis direction of the hinge mechanism 3 and is arranged symmetrically left and right. The other end passes around its respective guiding assembly 9 and is connected to the winch of the corresponding driving mechanism 6.

[0021] During specific implementation, a support frame 8 is provided on the fixed top cover 201. The support frame 8 includes four vertically arranged support legs and several support rods fixedly connected to the upper surface of the support legs. The lower surfaces of two of the support legs are fixed to the two ends of the upper surface of the fixed top cover 201 parallel to the axis direction of the hinge mechanism 3, and the lower surfaces of the other two support legs are fixed to the ground area directly opposite the middle of the rear bottom edge line of the slag box. The driving mechanism 6 is arranged between the two support legs on the ground; two sets of guiding assemblies 9 are symmetrically installed on the opposite sides of the upper surface of the support rods; Each set of guiding assemblies 9 includes four steering wheels distributed in a rectangle. Among them: The first steering wheel 901 and the second steering wheel 902 are arranged along a diagonal line of the rectangle where they are located, and their rotating shafts are parallel to the upper surface of the support rod; The third steering wheel 903 and the fourth steering wheel 904 are arranged along the other diagonal line of the rectangle where they are located, and their rotating shafts are perpendicular to the upper surface of the support rod; One end of each of the two traction steel wires 7 is fixed to the movable top cover 202, and the other end sequentially passes around the first steering wheel 901, the third steering wheel 903, the fourth steering wheel 904, and the second steering wheel 902 of the corresponding side guiding assembly 9, and then the two traction steel wires 7 are bundled to the winch of the corresponding driving mechanism 6. Such a setting is because factory building columns are provided in the ground areas directly opposite the two ends of the rear bottom edge line of the slag box, making it impossible to install the driving mechanism 6 in the ground areas directly opposite the two ends of the rear bottom edge line of the slag box. Therefore, in this embodiment, the driving structure is changed to be arranged in the ground area directly opposite the middle of the rear bottom edge line of the slag box; and since the fixing points of the traction steel wires 7 and the movable top cover 202 are located at positions close to the two ends of the movable top cover 202, the steering wheels are set in this way in the present application to horizontally translate the traction steel wires 7 to a position close to the middle and then vertically downward to the driving structure to bypass the factory building columns and realize the opening and closing of the movable top cover 202.

[0022] During specific implementation, a limit sensor (not shown) is provided on the driving mechanism 6. The length of the wire rewinding is monitored through the limit sensor. When the length of the wire rewinding reaches the set value, the driving mechanism 6 is triggered to stop working. In this way, by monitoring the length of the wire rewinding, the opening and closing angle of the movable top cover 202 can be indirectly limited, thereby avoiding the opening and closing angle of the movable top cover 202 being too large, resulting in the inability of the movable top cover 202 to be closed again by the gravity of the movable top cover 202.

[0023] In specific implementation, a plurality of limiting rods 4 are vertically and spacedly arranged near the edge of the fixed top cover 201 close to the hinge mechanism 3. In this way, when the limit sensor fails, the opening and closing angle of the movable top cover 202 can still be limited by mechanical limitation, so that it can only open and close between the overlapping position and the vertical position. Because after exceeding the vertical position, even if the traction wire 7 is released, the movable top cover 202 cannot return to the original overlapping state by gravity, thus avoiding the excessive opening and closing angle of the movable top cover 202, resulting in the inability of the movable top cover 202 to be closed again by the gravity of the movable top cover 202.

[0024] In specific implementation, the hinge mechanism 3 is a hinge shaft or a plurality of hinge hinges arranged at intervals. When the hinge mechanism 3 is a hinge hinge, the hinge hinge includes two mutually hinged blades, one of which is fixed to the fixed top cover 201 and the other is fixed to the movable top cover 202.

[0025] In specific implementation, the number of dust removal pipes 5 can be determined according to the size of the slag box, such as one, two or three, etc.

[0026] Usage method: When it is necessary to open and close the movable top cover 202, the motor of the driving mechanism 6 is powered on. After the motor of the driving mechanism 6 is powered on, the power is transmitted to the speed reducer on the driving mechanism 6, and the speed reducer drives the hoisting wheel to rotate, so as to realize the winding back or release of the traction wire 7, thereby driving the movable top cover 202 to open or close. When the length of the wire rewinding reaches the set value, the limit sensor transmits a signal to the control cabinet to control the driving mechanism 6 to stop working; when the limit sensor fails, mechanical limitation is carried out through the limiting rod 4 on the fixed top cover 201 to prevent the opening and closing angle of the movable top cover 202 from being too large, resulting in the inability of the movable top cover 202 to be closed again.

[0027] When it is necessary to pour molten steel slag into the slag box, first drive the traction wire 7 through the driving mechanism 6 to open the movable top cover 202, then pour the high-temperature molten steel slag into the slag box, and at the same time spray water on the molten steel slag in the slag box for cooling. At this time, a large amount of water mist will be generated. Drive the traction wire 7 through the driving structure to close the movable top cover 202, and a large amount of water mist and dust generated are sucked away through the dust removal pipe 5 at the top of the fixed top cover 201, so as to ensure the cleanliness of the on-site environment.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the technical solutions. Those of ordinary skill in the art should understand that those who modify or equivalently replace the technical solutions of the present invention without departing from the purpose and scope of the present technical solution should be covered by the scope of the claims of the present invention.
