Technical Field

[0001] This utility model relates to the field of refractory material processing technology for tundishes, specifically a crushing device for refractory material processing for tundishes. Background Technology

[0002] The tundish, also known as a tundish or transition ladle, is a key thermal device located between the ladle and the crystallizer in modern continuous casting processes. During the use of the tundish, to increase material utilization and reduce material loss, a crushing device is used to crush the waste material from the tundish for subsequent reuse.

[0003] The crushing device, during operation, uses relatively rotating crushing rollers to crush the refractory material in the slurry pump, facilitating subsequent material processing. However, existing crushing devices generate significant dust during the feeding of refractory material into the tundish, potentially impacting the environment and workers. Furthermore, prolonged operation of the filter bags during dust extraction can affect gas flow and damage the bags. Therefore, this paper proposes a crushing device for tundish refractory processing to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a crushing device for refractory material processing in tundishes, so as to solve the problems mentioned in the background art. In the process of using existing crushing devices, the refractory material in the tundishes generates a lot of dust, which can easily affect the environment and workers. In addition, the long-term operation of the filter bag during the dust extraction process can easily affect its gas throughput and cause damage to the filter bag.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for processing refractory intermediate ladles, comprising a support frame, wherein a first motor device is provided inside the support frame, one end of the output shaft of the first motor device is connected to a drive wheel via a coupling, and a driven wheel is correspondingly provided on one side of the drive wheel between the support frame and the drive wheel. A conveyor belt is fitted on the outer wall of the drive wheel and the driven wheel, and refractory intermediate ladles are placed on top of the conveyor belt. A protective cover is provided on the upper end face of the support frame, and one end of the conveyor belt and the protective cover is inserted into the feed box. The feed box is located above the crusher body, and multiple sets of crushing rollers are connected inside the crusher body via a second motor device. A dust suction port is placed on top of the feed box, and a spiral rod is spirally provided on both sides of the outer wall of the dust suction port, and the lower end of the spiral rod is spirally attached to the feed box. A hollow hopper is inserted below the dust suction port, and a fixing plate is provided near the upper end of the hollow hopper. The fixing plate is inserted on the outside of the dust suction port, and multiple sets of first bolts are spirally provided on the fixing plate and the dust suction port.

[0006] The crusher body has multiple sets of fixing boxes on the rear outer wall, and the fixing boxes have fixing covers on the top. The fixing covers have spiral holes, and spiral tubes are spiraled inside the spiral holes. The spiral tubes are placed on the cloth bag, and a perforated plate is placed below the cloth bag inside the fixing box. An exhaust pipe is placed below the perforated plate. The fixing boxes have rubber pads on the back, and second bolts are inserted through the fixing boxes on both sides. The other end of the second bolts is spiraled onto the crusher body.

[0007] The dust suction port is equipped with an exhaust pipe at the top, and the other end of the exhaust pipe is connected to a three-way valve. The other end of the three-way valve is connected to a connecting pipe, and the other end of the connecting pipe is spirally inserted into the spiral hole on the fixed cover.

[0008] Preferably, the hollow hopper is connected to the dust suction port by a first bolt to form a spiral locking structure, and the dust suction port is connected to the feed box by multiple sets of spiral rods to form a spiral locking structure.

[0009] Preferably, the fixing box is connected to the crusher body via multiple sets of second bolts and rubber pads to form a spiral locking structure.

[0010] Preferably, the dust suction port is connected to the cloth bag via an exhaust pipe, a three-way valve, and a connecting pipe, and the cloth bag is also connected to the exhaust pipe via a fixing box and a perforated plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The hollow hopper of the crushing device for intermediate refractory processing forms a spiral locking structure with the dust suction port through the first bolt, and the dust suction port forms a spiral locking structure with the feed box through multiple sets of spiral rods. Thus, the feed box and protective cover prevent excessive dust overflow during the feeding process, while the hollow plate prevents some small hard materials from affecting the dust suction components. The fixing box of the device forms a spiral locking structure with the crusher body through multiple sets of second bolts and rubber pads. Thus, the service life of multiple sets of filter bags is increased by multiple sets of spirally installed fixing boxes, and the stability of the fixing box during use is ensured by the rubber pads. The dust suction port of the device forms a communication structure with the filter bags through the exhaust pipe, three-way valve, and connecting pipe, and the filter bags form a communication structure with the exhaust pipe through the fixing box and hollow plate. Thus, the three-way valve controls multiple sets of filter bags to work alternately, and when the filter bags collect too much dust and impurities or are damaged, the filter bags are compacted and replaced for operation.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a crushing device for processing refractory tundish, including a support frame 1. A first motor is installed inside the support frame 1. One end of the output shaft of the first motor is connected to a drive wheel via a coupling. A driven wheel is correspondingly provided on one side of the drive wheel between the support frame 1. A conveyor belt 2 is fitted onto the outer wall of the drive wheel and driven wheel. Refractory tundish is placed above the conveyor belt 2. A protective cover 3 is provided on the upper surface of the support frame 1, and one end of the conveyor belt 2 and the protective cover 3 passes through the feed... Inside the feed box 6, the feed box 6 is located above the crusher body 4, and multiple sets of crushing rollers 5 are connected inside the crusher body 4 through a second motor device. A dust suction port 7 is placed on the top of the feed box 6, and a spiral rod 10 is spiraled on both sides of the outer wall of the dust suction port 7. The lower end of the spiral rod 10 is spiraled on the feed box 6. A hollow hopper 8 is inserted below the dust suction port 7, and a fixing plate is provided near the upper end of the hollow hopper 8. The fixing plate is inserted on the outside of the dust suction port 7, and multiple sets of first bolts 9 are spiraled on the fixing plate and the dust suction port 7.

[0019] Furthermore, the hollow hopper 8 forms a spiral locking structure with the dust suction port 7 through the first bolt 9, and the dust suction port 7 also forms a spiral locking structure with the feed box 6 through multiple sets of spiral rods 10. Thus, the hollow hopper 8 and the dust suction port 7, which are spirally installed, can extract and process dust and other impurities when the refractory material in the intermediate ladle is fed, while preventing some harder materials from entering the dust suction port 7 and causing obstruction to related components.

[0020] The crusher body 4 has multiple sets of fixing boxes 15 on its rear outer wall, and the fixing boxes 15 have fixing covers 20 on their top. The fixing covers 20 have spiral holes, and spiral tubes are spiraled inside the spiral holes. The spiral tubes are placed on the cloth bag 14, and a perforated plate 17 is provided below the cloth bag 14 inside the fixing boxes 15. An exhaust pipe 16 is provided below the perforated plate 17. The fixing boxes 15 have rubber pads 19 on their back, and second bolts 18 are inserted through the fixing boxes 15 on both sides. The other end of the second bolts 18 is spiraled onto the crusher body 4. It should be noted that the fixing boxes 15 in this device are made of transparent material, so as to facilitate the inspection of the cloth bag 14 inside.

[0021] Furthermore, the fixing box 15 forms a spiral locking structure with the crusher body 4 through multiple sets of second bolts 18 and rubber pads 19. Thus, the service life of the fixing box 15 can be increased by the rubber pads 19, and the fixing box 15 with multiple sets of spiral installation can protect the filter bag 14 without affecting its operation.

[0022] The suction port 7 is equipped with an exhaust pipe 11 at its top, and the other end of the exhaust pipe 11 is connected to a three-way valve 12. The other end of the three-way valve 12 is connected to a connecting pipe 13, and the other end of the connecting pipe 13 is spirally inserted into a spiral hole on the fixed cover 20. It should be noted that each group of electrical components in this device is equipped with heat dissipation and shock absorption components during installation to ensure normal operation. The exhaust pipe 16 is equipped with a butterfly valve, and another group of exhaust pipes 16 is connected to the exhaust gas treatment equipment through the exhaust fan assembly, which facilitates the treatment of extracted dust and impurities and the purification of the air. Purification: This utility model is a crushing device for refractory material processing in intermediate ladles. All components are standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In this device, all the electrical components mentioned above refer to power elements, electrical components, and the matching monitoring computer and power supply, which are connected by wires. The specific connection method should refer to the working principle above, and the electrical connection between each electrical component should be completed in the order of operation. The detailed connection method is a well-known technology in the field.

[0023] Furthermore, the suction port 7 is connected to the filter bag 14 via the exhaust pipe 11, the three-way valve 12, and the connecting pipe 13. The filter bag 14 is also connected to the exhaust pipe 16 via the fixing box 15 and the perforated plate 17. Thus, the three-way valve 12 allows multiple filter bags 14 to work alternately, thereby preventing one set of filter bags 14 from working for a long time or from being damaged, which would affect the suction process.

[0024] Working Principle: Using the refractory material crushing device for intermediate ladle processing, the intermediate ladle is first initially crushed, and the material undergoes magnetic separation and other processing. The screened refractory material is then transported and fed via conveyor belt 2. Subsequently, the crusher and related equipment are started, and each group of electrical components operates according to the prescribed procedures. The refractory material is transported via conveyor belt 2 to the receiving box 6 for feeding. Simultaneously, the protective cover 3 and the receiving box 6 reduce dust overflow during the feeding process, thus preventing excessive dust and impurities from affecting the surrounding environment and the health of workers. During the feeding process, the dust suction port 7, under the action of the exhaust fan, uses appropriate airflow to extract dust and impurities, further preventing excessive dust pollution of the processing environment. At the same time, the spiral-installed perforated hopper 8 prevents harder materials from entering the dust suction port 7 and affecting related components. The extracted material then enters one of the filter bags 14 through the exhaust pipe 11, three-way valve 12, and connecting pipe 13. The filter bag 14 is moved to the corresponding processing equipment for further purification via the exhaust pipe 16 below it. During use, the filter bag 14 is protected by the fixing box 15, which effectively increases the service life of the filter bag 14. At the same time, the hollow plate 17 component prevents dust and impurities from directly entering the subsequent processing equipment and hindering the purification process when the filter bag 14 is damaged. The fixing box 15 is reinforced with rubber pads 19 to increase its stability during use. The filter bag 14 can be inspected through the transparent fixing box 15 during operation. If the filter bag 14 is damaged or collects too many impurities, it can be replaced with another set of filter bags 14 via the three-way valve 12, thus ensuring the working effect of the dust collection component during the crushing of the intermediate ladle refractory material. The intermediate ladle refractory material after feeding is crushed by the relatively rotating crushing roller 5 and discharged through the discharge port below it. This is the operation process of the crushing device for intermediate ladle refractory material processing.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
