Description

Technical Field

[0001] This utility model relates to the field of refractory brick waste collection technology, and in particular to a waste collection device for cast steel refractory bricks. Background Technology

[0002] In the steelmaking process, cast steel refractory bricks, as important refractory materials, are widely used in high-temperature equipment such as ladles and tundishes. However, with the increase of service time, refractory bricks will gradually wear down and crack, eventually forming waste. If these wastes are not effectively treated and recycled, they will not only waste resources but also pollute the environment. Therefore, developing an efficient waste collection device for cast steel refractory bricks is of great significance for improving resource utilization and reducing environmental pollution.

[0003] Currently, existing technologies for treating refractory brick waste mainly rely on traditional crushing and screening equipment. This equipment typically includes crushers, vibrating screens, and conveyor belts. The crusher uses mechanical force to break large pieces of refractory brick waste into smaller particles, which are then screened by the vibrating screen. The conveyor belt is used to transport the screened waste to the collection point. Although these devices can achieve preliminary treatment of the waste to a certain extent, there are still some problems in practical applications.

[0004] However, existing technologies have a significant problem in processing steel casting refractory brick waste: the waste sorting and collection efficiency is low. Because existing equipment usually uses a single screening method, it cannot perform multi-stage screening and sorting collection of waste, resulting in waste of different particle sizes being mixed together, making it difficult to achieve effective resource recovery and reuse. This not only reduces the recycling value of the waste, but also increases the difficulty and cost of subsequent processing. Therefore, there is a need for a steel casting refractory brick waste collection device that can achieve efficient sorting and collection to improve the waste recycling efficiency and resource utilization rate. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a waste collection device for cast steel refractory bricks, which aims to improve the situation where a single screening method cannot perform multi-stage screening and classification collection of waste, resulting in waste of different particle sizes being mixed together, making it difficult to achieve effective recycling and utilization of resources. This not only reduces the recycling value of waste, but also increases the difficulty and cost of subsequent refractory brick waste treatment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste collection device for steel casting refractory bricks, including a box body, an inner box fixedly connected inside the box body, and a multi-stage screening component installed inside the box body;

[0007] The multi-stage screening assembly includes a screen cylinder and a screen plate. One side of the screen cylinder is fixedly connected to the outer wall of the transmission box. An auger blade is rotatably connected inside the transmission box. The outer wall of the auger blade is rotatably connected to the inner wall of the screen cylinder. A guide pipe is fixedly connected to the outer wall of the screen cylinder. A receiving box is provided at one end of the guide pipe. A guide plate is fixedly connected to the inner wall of the inner box. A secondary crushing assembly is installed inside the inner box. A screen plate is provided on the inner wall of the inner box. A spring is fixedly connected to the lower surface of the screen plate. A vibration motor is fixedly connected to the lower surface of the screen plate. A fixing plate is fixedly connected to one end of the spring. A filter element is fixedly connected to one side of the outer wall of the fixing plate inside the inner box. A fan is fixedly connected to the upper surface of the filter element. A dust suction pipe is fixedly connected to the input end of the fan. One end of the dust suction pipe is fixedly connected to the outer wall of the inner box. A dust discharge pipe is fixedly connected to the output end of the fan. One end of the dust discharge pipe is fixedly connected to the inner wall of the box.

[0008] Furthermore, the crushing assembly includes a motor and two crushing rollers. One side of the motor is fixedly connected to one side of the outer wall of the transmission box. The output end of the motor is fixedly connected to one of the crushing rollers. Both crushing rollers are rotatably connected inside the transmission box. One end of one crushing roller is fixedly connected to a gear, and one end of the other crushing roller is fixedly connected to a gear. The gears are meshed. The other end of one crushing roller is connected to one end of the auger blade by a belt.

[0009] Furthermore, the secondary crushing assembly includes a second motor and two crushing rollers. One side of the second motor is fixedly connected to one side of the outer wall of the inner box, and the output end of the second motor is fixedly connected to one end of one of the crushing rollers. Both crushing rollers are rotatably connected inside the inner box. The other end of one crushing roller is fixedly connected to a third gear, and one end of the other crushing roller is fixedly connected to a fourth gear. The fourth gear meshes with the third gear.

[0010] Furthermore, a second receiving box is slidably connected to one side of the lower surface of the inner box, and the second receiving box is located directly below the sieve plate.

[0011] Furthermore, a receiving box three is slidably connected to the other side of the lower surface of the inner box, and the receiving box three is disposed on one side of the sieve plate.

[0012] Furthermore, the inner wall of the inner box is fixed with symmetrical guide plates, and the two guide plates are arranged between the screen cylinder and the rolling roller.

[0013] Furthermore, a feed hopper is fixedly connected to the upper surface of the transmission box, and the receiving box slides through the inside of the box body.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, when refractory brick waste enters the feed hopper, it is crushed by the crushing roller. The crushed waste falls into the transmission box, where the rotation of the auger blades facilitates the initial screening of the waste into the screen cylinder. The screened waste falls into the crushing roller, while the waste that does not pass through the screen cylinder falls into the first collection box through the guide pipe. The crushed waste then falls above the screen plate, where the vibrating motor and spring work together to further screen the waste. The screened waste falls into the second collection box, while the waste that does not pass through the screen falls into the third collection box due to the tilt and fixation of the screen plate. This process achieves classified collection of waste, thereby improving the practicality of the device.

[0016] In this invention, when dust is generated during the operation of the device, the dust is first drawn into the filter element by starting the fan and simultaneously by the dust suction pipe that runs through the inner box. The dust is then deeply filtered by the filter element and discharged out of the box through the dust discharge pipe, thereby improving the practicality of the device. Attached Figure Description

[0027] Working Principle: When collecting refractory brick waste, the waste is first fed into the feed hopper 1. Then, motor 3 is turned on, causing one of the crushing rollers 21 to rotate. This, in turn, drives gear 5 to rotate. The rotation of gear 5 then causes gear 6, which meshes with it, to rotate, thus crushing the waste. The rotation of gear 6 causes belt 4 to rotate, which in turn drives the auger blade 17 inside the transfer box 7 on one side of the crushing roller 21. The crushed waste falls into the transfer box 7, and the rotation of the auger blade 17 transports the waste into the screen cylinder 13 for preliminary screening. Waste that cannot pass through the screen holes is then guided through... The material pipe 22 falls into the receiving box 20. At this time, the waste material after preliminary screening enters the crushing roller 10 through the guide plate 11. At this time, the motor 28 is started, causing the gear 3 24 to rotate. At this time, the gear 3 24 and the gear 4 23 mesh and connect, thereby realizing the rotation of the crushing roller 10. At this time, the waste material is crushed by the crushing roller 10 and falls above the screen plate 12 through the guide plate 11. At this time, the vibration of the vibrating motor 28, combined with the synergistic action of the spring 26, achieves the effect of secondary screening of the waste material. At this time, the waste material that passes through the screen holes of the screen plate 12 can fall directly into the receiving box 25. At this time, because the screen plate 12 is tilted and fixed to the inner wall of the inner box 8, the waste material that has not passed through the screen holes of the screen plate 12 slides down into the receiving box 3 9.

[0028] In addition, by starting the fan 15, the dust generated during the operation of the equipment is transported into the filter element 14 by the dust suction pipe 27 that runs through the inner box 8. At this time, the filtered dust is discharged from the box 2 through the dust discharge pipe 16.
