Description

Technical Field

[0001] The invention relates to a metal smelting technology, and more specifically to an integrated stirring and slag scooping device for metal smelting. Background Art

[0002] At present, the molten metal needs to be stirred during the metal smelting process to improve the temperature uniformity and speed up the smelting speed of the metal. The traditional method is to use a stirring rod to stir it manually, which is inconvenient to operate. After the metal is smelted, slag will float on the surface of the melt. In order to ensure the quality of the product, the slag needs to be cleaned. The traditional cleaning method is to manually hold a slag scoop and wear protective tools to remove the slag from the surface of the melt. This manual melt stirring and slag cleaning method is not only labor-intensive, but also has safety hazards. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention provides an integrated stirring and slag-removing device for metal smelting, which combines the functions of melt stirring and slag cleaning. Melt stirring and slag cleaning are completed automatically, reducing labor intensity and avoiding safety hazards.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a stirring and slag scooping integrated device for metal smelting, comprising a base, a transverse displacement seat installed on the base for transverse movement, and a lifting seat installed on the transverse displacement seat for lifting and lowering, an extension arm is provided on the lifting seat, a rotating shaft is installed on the extension arm, the rotating shaft extends downward, and stirring blades are installed on the rotating shaft, an adapter seat is hinged on the extension arm, the adapter seat is connected to a driving mechanism and a slag scooping mechanism, and the driving mechanism drives the adapter seat to rotate to make the slag scooping mechanism work.

[0005] The entire device is installed next to the smelting furnace. When stirring the melt in the smelting furnace, the transverse seat moves horizontally so that the stirring blade reaches the top of the smelting furnace, and then the lifting seat moves downward so that the stirring blade extends into the melt, and the rotating shaft rotates so that the stirring blade stirs the melt. During the stirring process, the transverse seat moves horizontally to stir each position of the smelting furnace. After the stirring is completed, the lifting seat moves upward so that the stirring blade leaves the melt. When slag removal is performed on the melt in the smelting furnace, the transverse seat moves into position so that the slag removal mechanism is placed above one end of the smelting furnace, and then the lifting seat moves downward so that the lower end of the slag removal mechanism is placed on the surface of the melt, the transverse seat moves, and the driving mechanism drives the transfer seat to rotate so that the slag removal mechanism works to remove the slag on the surface of the melt. After the slag removal is completed, the lifting seat and the transverse seat return to their positions. This integrated stirring and slag removal device for metal smelting combines the functions of melt stirring and slag cleaning. Melt stirring and slag cleaning are completed automatically, which reduces labor intensity and avoids safety hazards.

[0006] Preferably, the driving mechanism comprises a piston cylinder, a push-pull rod, and a connecting seat, one end of the push-pull rod is hinged on the adapter seat, the other end of the push-pull rod is hinged on the connecting seat, and the piston cylinder telescopic rod is hinged on the connecting seat.

[0007] The piston rod telescopic rod telescopes and moves, driving the push-pull rod to push and pull, thereby realizing the forward and reverse rotation of the adapter, driving the slag scooping mechanism to operate the slag scooping operation on the slag on the surface of the melt.

[0008] Preferably, a limit block for abutting and limiting the extension arm is installed on the connecting seat.

[0009] The limit block limits the rotation angle of the connecting seat, thereby limiting the telescopic distance of the piston rod telescopic rod, and further limiting the rotation angle of the adapter seat to avoid excessive rotation.

[0010] Preferably, the slag scooping mechanism includes a connecting arm, a connecting rod, and a slag scooping bucket, wherein the connecting arm and the connecting rod are hinged between the slag scooping bucket and the adapter seat; the connection position of the connecting arm and the adapter seat, and the connection position of the connecting rod and the adapter seat are staggered; the connection position of the connecting arm and the slag scooping bucket, and the connection position of the connecting rod and the slag scooping bucket are staggered.

[0011] After the adapter rotates clockwise to the right position, the connecting arm and the connecting rod are placed horizontally, and the slag bucket is in the highest position. The adapter rotates counterclockwise, and the connecting arm and the connecting rod rotate downward to place the slag bucket at the lowest position. At this time, the transverse seat and the lifting seat move into position to ensure that the slag bucket is placed at the liquid level of the melt at one end of the smelting furnace. The slag bucket moves from one side of the smelting furnace to the other side with the transverse seat. The adapter rotates clockwise to flip the slag bucket upward, and the slag is placed in the slag bucket. Then the transverse seat and the lifting seat move to drive the slag bucket to the position where the slag is placed. The adapter rotates counterclockwise to flip the slag bucket downward, and the slag in the slag bucket falls.

[0012] Preferably, a support is installed on the extension arm, and the adapter seat is in a T-shaped structure. A hinge point is set at the three end positions of the T-shaped adapter seat. The middle hinge point is hinged to the support, and the other two hinge points are respectively hinged to the drive mechanism and the connecting rod. The connecting arm is hinged to the middle hinge point on the adapter seat.

[0013] The adapter is hinged to the support on the extension arm, which is convenient for connection. Three hinge points are set on the adapter to ensure the reliable operation of the slag scooping mechanism.

[0014] Preferably, a plurality of filter holes are provided on the slag hopper.

[0015] The filter holes facilitate the passage of the melt through the filter holes during the slag removal process.

[0016] Preferably, two transverse slide rails are provided on the base, and transverse rollers are installed on both sides of the transverse seat, and the transverse rollers are adapted to be installed on the transverse slide rails; a rack is installed on the base, a transverse motor is installed on the transverse seat, a gear is installed on the output shaft of the transverse motor, and the gear and the rack are meshed for transmission.

[0017] The lateral movement motor rotates, causing the gear and rack to adapt and transmit, thereby realizing the lateral movement of the lateral movement seat. During the movement, the lateral movement roller slides on the lateral movement rail, which is stable and reliable.

[0018] Preferably, a lifting motor is installed on the top of the transverse shift seat, a reel is installed on the output shaft of the lifting motor, the reel is connected to a steel belt, the lower end of the steel belt is connected to the lifting seat, and the steel belt is wound on the reel to drive the lifting seat to move upward.

[0019] The lifting motor rotates to drive the reel to rotate, winding the steel belt on the reel, thereby lifting the lifting seat upward and moving the lifting seat upward. The lifting motor reverses, the steel belt wound on the reel is lowered, and the lifting seat moves downward under the action of gravity.

[0020] Preferably, a driven wheel is installed on the upper part of the rotating shaft, the rotating shaft is installed at the outer end of the extension arm, the stirring motor is installed on the lifting seat near the other end of the extension arm, the driving wheel is installed on the output shaft of the stirring motor, and the driving wheel and the driving wheel are connected by transmission. The stirring motor rotates, and the rotating shaft rotates through the transmission connection between the driving wheel and the driven wheel, and the operation is stable and reliable.

A sliding groove is provided on the sliding sleeve, and a track groove of a trapezoidal frame structure is provided on the mounting seat. There is a guide pin on the slag crushing rod, and the guide pin passes through the sliding groove and is fitted and inserted together with the track groove, so as to push the telescopic rod of the piston cylinder to be connected with the sliding sleeve.

[0022] During the slag scooping process, the piston cylinder is pushed to drive the slag crushing rod to move horizontally and lift at the same time. The slag crushing rod moves horizontally to push the slag agglomerated in front of the slag scooping bucket toward the slag scooping bucket. The slag crushing rod squeezes the slag to crush the slag, making it easier to collect the slag in the slag scooping bucket. After the slag crushing rod moves upward, it moves back horizontally in the opposite direction to prevent the lower end of the slag crushing rod from moving in the melt and pushing the slag away from the slag scooping bucket, affecting the slag scooping effect.

[0023] Compared with the prior art, the present invention has the following beneficial effects: (1) the integrated stirring and slag scooping device for metal smelting combines the functions of melt stirring and slag cleaning, and melt stirring and slag cleaning are completed automatically, thereby reducing labor intensity and avoiding safety hazards; (2) the agglomerated slag can be broken during the slag scooping process, making it easier for the slag to be collected in the slag scooping bucket.
