[0002] The tundish is an important functional refractory material in the continuous casting process. It receives molten steel from the tundish to the mold and is the key to realizing oxidation-free pouring of molten steel. It is used in large quantities during production. After the tundish is poured, on the inner surface of the tundish under the scouring of molten steel, part of the molten steel will adhere to the inner wall of the tundish, forming a steel shell.
[0003] After the tundish is taken offline, workers usually use knocking tools to break the tundish to recycle the residual steel shell and refractory material on the inner wall for reuse. However, the manual knocking method has low efficiency, high labor intensity, high labor cost, and at the same time, it will cause environmental pollution during the knocking process and affect the physical health of operators. Summary of the Invention
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a crushing and recycling system for continuous casting tundishes, which can crush the tundish in an efficient and mechanized manner, recycle the steel shell at the same time, reduce labor costs, and avoid environmental pollution.
[0005] To achieve the above purpose, the utility model proposes the following technical solutions:
[0006] A crushing and recycling system for continuous casting tundishes includes a hydraulic cylinder, a pressure block, a fixed bracket, a pressure-receiving platform, a platform support frame, a chute, a slag pusher, and a sieve.
[0007] The pressure-receiving platform is arranged on the platform support frame. The cylinder body of the hydraulic cylinder is arranged above the pressure-receiving platform through the fixed bracket, and the cylinder rod of the hydraulic cylinder is arranged downward. The pressure block is arranged at the bottom of the cylinder rod of the hydraulic cylinder. The hydraulic cylinder drives the pressure block to move downward to crush the tundish on the pressure-receiving platform.
[0008] The chute and the slag pusher are respectively arranged on the left and right sides of the pressure-receiving platform. The slag pusher can push the crushed blocks and steel shells on the pressure-receiving platform into the chute.
[0009] The slag pusher includes a push rod and a push plate. The push rod is fixed on one side of the push plate, and the other side of the push plate is used to push the crushed blocks and steel shells.
[0010] The sieve is a container with an open top. The sieve is arranged below the outlet of the chute for receiving the crushed blocks and steel shells. A sieve mesh is arranged in the sieve to screen and extract the steel shells. The crushed blocks and steel shells enter the sieve through the chute. The steel shells will remain on the sieve mesh, and the crushed blocks will fall through the sieve mesh to the bottom of the sieve.
[0011] Preferably, the pressure block is a 50-mm thick hard metal plate, such as a steel plate.
[0012] Preferably, the top of the fixing bracket is a cover plate. The cylinder block of the hydraulic cylinder is arranged at the top of the fixing bracket. The pressure block is placed inside the fixing bracket and above the pressure-receiving platform. The cylinder rod of the hydraulic cylinder passes through the top of the fixing bracket and is connected to the pressure block. The pressure block moves up and down inside the fixing bracket, which can reduce the impact on the environment during the nozzle breaking process to a certain extent, and at the same time reduce the damage to the hydraulic cylinder to a certain extent and extend its service life.
[0013] Preferably, a first dust-proof plate, a second dust-proof plate, a third dust-proof plate, and a fourth dust-proof plate are arranged around the fixing bracket on the pressure-receiving platform. The first dust-proof plate is arranged on the front side, and a placement opening is formed on the first dust-proof plate. A delivery door is arranged inside the first dust-proof plate. The delivery door slides up and down inside the first dust-proof plate to open and close the placement opening. When the delivery door slides down to the bottom, the placement opening can be closed. When the delivery door slides up, the placement opening can be opened, and the nozzle can be placed on the pressure-receiving platform.
[0014] The second dust-proof plate is arranged on the left side, and a slag pushing opening is formed on the second dust-proof plate. The push rod of the slag pusher passes through the slag pushing opening. The push plate is placed inside the pressure-receiving platform. The height of the push plate is greater than the height of the slag pushing opening, and the length of the push plate is greater than the length of the slag pushing opening, so that the push plate can block the slag pushing opening.
[0015] The third dust-proof plate is placed on the right side, and a slag discharging opening is formed on the third dust-proof plate. A chute is connected to the slag discharging opening. A slag blocking door is arranged on the third dust-proof plate. The slag blocking door slides up and down inside the third dust-proof plate to open and close the slag discharging opening. When the slag blocking door slides down to the bottom, the slag discharging opening can be closed. When the slag blocking door slides up, the slag discharging opening can be opened. A handle and a baffle are arranged on the slag blocking door. The baffle is used to block the slag discharging opening, and the handle is provided for moving the slag blocking door up and down.
[0016] The fourth dust-proof plate is placed on the rear side to completely enclose the rear side of the pressure-receiving platform. By arranging the first dust-proof plate, the second dust-proof plate, the third dust-proof plate, and the fourth dust-proof plate, the pressure-receiving platform is in a relatively closed state during pressure crushing, avoiding environmental pollution and protecting the safety of operators.
[0017] Preferably, the delivery door and the slag blocking door have a certain self-weight to further stabilize the closed state of the placement opening and the slag discharging opening.
[0018] Preferably, the delivery door and the slag blocking door are made of iron to enhance the stability of the closed environment.
[0019] Preferably, the push plate of the slag pusher is made of iron.
[0020] During actual use, in the initial state, the placement opening, slag pushing opening, and slag discharging opening are all in the closed state. That is, the feeding door closes the placement opening, the slag blocking door closes the slag discharging opening, and at the same time, the push plate of the slag pusher blocks the slag pushing opening. Then, the feeding door of the first dust-proof plate is lifted to open the placement opening, and the water block is placed on the pressure platform. Then, the feeding door moves down to close the placement opening. The pressure block is driven by the hydraulic cylinder to crush the water block. After the crushing is completed, the slag blocking door is pulled up to open the slag discharging opening, and then the push rod is pushed so that the push plate pushes the crushed blocks and the steel shell into the chute and falls into the sieve for screening. After completion, the placement opening, slag pushing opening, and slag discharging opening return to the initial state for the next use.
[0021] Preferably, the sieve is a vibrating sieve, including a base, a main shaft, and a sieve box. The sieve box is connected to the base through the main shaft. The sieve mesh is arranged in the sieve box, and the sieve box is open at the top. An exciter is arranged in the base, and the exciter provides vibration force to the sieve box through a driving motor, so that the crushed blocks and the steel shell are fully screened on the sieve mesh.
[0022] The above-mentioned vibrating sieve and the method of screening using the vibrating sieve belong to the existing content in the prior art, which is known to those skilled in the art.
[0023] Preferably, it further includes a magnetic adsorption manipulator and a recycling box. The recycling box is arranged beside the magnetic adsorption manipulator. The magnetic adsorption manipulator includes a manipulator base, a rotating base, a lifting oil cylinder, a lifting oil cylinder, and an electromagnetic chuck. The manipulator base is arranged beside the sieve. The rotating base is rotatably arranged on the manipulator base. A servo motor and a rotating rod are arranged in the manipulator base. The servo motor is connected to the rotating base through the rotating rod. The operation of the servo motor drives the rotating rod and the rotating base to rotate. The cylinder body of the lifting oil cylinder is arranged on the rotating base, and the rotating base rotates synchronously with the lifting oil cylinder. The cylinder rod of the lifting oil cylinder is connected to the lifting oil cylinder through a horizontal connecting rod. The cylinder rod of the lifting oil cylinder is arranged downward and connected to the electromagnetic chuck. The lifting oil cylinder drives the electromagnetic chuck to lift. The electromagnetic chuck includes an iron core, a coil wound around the iron core, and an electromagnetic control motor for supplying power to the coil. When the coil is energized, the iron core has magnetism, and when the coil is de-energized, the magnetism disappears. The electromagnetic control motor controls the presence or absence of magnetism of the iron core through the coil. The electromagnetic chuck can move into the sieve or above the recycling box. When the electromagnetic chuck has magnetism, it can pick up the steel shell. When the magnetism of the electromagnetic chuck disappears, the steel shell can fall into the recycling box.
[0024] The connection method of the above-mentioned manipulator base and the rotating base, the method of driving the rotating base to rotate by the servo motor, as well as the structure and magnetic control method of the electromagnetic chuck all belong to the existing content in the prior art, and those skilled in the art can directly use them.
[0025] When it is necessary to extract the steel shell, first operate the lifting oil cylinder to adjust the electromagnetic chuck to an appropriate height. Then operate the servo motor to drive the rotating base to rotate so that the electromagnetic chuck is aligned directly above the sieve. Then start the lifting oil cylinder to lower the electromagnetic chuck close to the steel shell. Start the electromagnetic control motor. The electromagnetic chuck becomes magnetic and adsorbs the steel shell. Subsequently, start the lifting oil cylinder to lift the electromagnetic chuck so that the electromagnetic chuck with the adsorbed steel shell is separated from the sieve. Then start the servo motor to drive the rotating base to rotate, turn the electromagnetic chuck to align with the recycling bin, place it above the recycling bin, start the lifting oil cylinder to make the electromagnetic chuck reach an appropriate height, and then operate the electromagnetic control motor to make the magnetism of the electromagnetic chuck disappear. At this time, the steel shell falls into the recycling bin, and thus the recycling work of the steel shell is completed.
[0026] Specifically, place the nozzle on the pressure-receiving platform, and then operate the hydraulic cylinder. The pressure block moves downward to crush the nozzle. After crushing, operate the slag pusher to make the crushed pieces and the steel shell fall into the sieve along the chute. The steel shell remains on the sieve mesh, and the crushed pieces fall to the bottom of the sieve.
[0027] The beneficial effects of the present utility model are as follows:
[0028] The present utility model forms a complete crushing and recycling system for continuous casting nozzles through a hydraulic cylinder, a pressure block, a fixed bracket, a pressure-receiving platform, a platform support frame, a chute, a slag pusher, and a sieve, which is efficient and convenient, reduces labor costs, and avoids environmental pollution.
[0029] The present utility model sets a first dust-proof plate, a second dust-proof plate, a third dust-proof plate, and a fourth dust-proof plate around the fixed bracket on the pressure-receiving platform, so that the pressure-receiving platform is in a relatively closed state during pressure crushing, avoiding environmental pollution and protecting the safety of operators.
