Description

Technical Field

[0001] This utility model relates to the field of rolling mill dust removal technology, and in particular to a rolling mill dust removal device. Background Technology

[0002] Currently, dust collection devices in rolling mills typically employ two methods: absorption and flushing. The absorption method uses an air pump to generate suction at the pipe port, drawing dust into the collection device. While this method effectively removes dust, it presents certain problems during use. Once sucked in, dust often enters the pump body with the airflow, leading to dust accumulation inside the pump and affecting its normal operation. In severe cases, this can cause blockage or damage to the pump, thus shortening its lifespan. Therefore, a new rolling mill dust collection device is needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. Currently, dust collection devices in rolling mills typically employ two methods: absorption and flushing. The absorption method uses an air pump to generate suction at the pipe port, drawing dust into the collection device. While this method effectively removes dust, it presents certain problems during use. Once sucked in, dust often enters the pump body with the airflow, leading to dust accumulation inside the pump and affecting its normal operation. In severe cases, this can cause blockage or damage to the pump, thus shortening its lifespan. Therefore, this invention provides a rolling mill dust collection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rolling mill dust removal device, comprising a device housing, a fixed frame fixedly connected to the bottom of the device housing, a sliding frame slidably connected to the inner wall of the fixed frame, a support shell fixedly connected to the bottom of the sliding frame, an arc-shaped plate fixedly connected to the inner wall of the support shell, a transfer pipe fixedly connected to the bottom of the device housing, an air inlet pipe fixedly connected to the bottom of the transfer pipe, the other end of the transfer pipe being fixedly connected to the port of the dust suction end pipe of the device housing, an input end fixedly connected to the bottom of the device housing, and a sliding connection between the support shell and one side of the arc-shaped plate and the outer surface of the transfer pipe.

[0005] In a preferred embodiment, a plurality of fixing blocks are fixedly connected to the bottom of the device housing, and a rotating plate is rotatably connected between one side of each pair of fixing blocks. Rotating grooves are opened on both sides of the rotating plate, and a rotating rod is rotatably connected to the inner wall of the rotating groove. One end of the rotating rod is rotatably connected to one side of the fixing block.

[0006] In a preferred embodiment, a torsion spring is provided on the outer surface of the rotating rod, one end of the torsion spring is fixedly connected to one side of the fixing block, and the other end of the torsion spring is fixedly connected to the inner wall of the rotating groove.

[0007] In a preferred embodiment, the bottom of the rotating plate is fixedly connected to a fixed shell, and the inner wall of the fixed shell is slidably connected to a clamping plate.

[0008] In a preferred embodiment, a groove is formed on the top of the card plate, and multiple telescopic rods are fixedly connected to the inner wall of the groove. One end of each telescopic rod is fixedly connected to the top of the fixed shell, and a pull hole is formed on one side of the card plate.

[0009] In a preferred embodiment, a spring is provided on the outer surface of the telescopic rod, one end of the spring is fixedly connected to the inner wall of the fixed shell, and the other end of the spring is fixedly connected to the inner wall of the groove.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, the air inlet and input ends of the pump body within the outer casing are fixedly connected, while the dust suction port on the outer casing is fixedly connected to the adapter pipe, thus forming a flow structure. When the pump body is turned on, the gas at the port of the outer casing passes through the adapter pipe, air inlet pipe, support shell, and input end to reach the pump body. Inside the support shell, liquid is placed to absorb dust. The dust carried by the gas changes its flow direction through an arc-shaped plate, causing it to come into contact with the liquid inside the support shell. Through liquid adsorption, the dust carried by the gas reaching the top of the arc-shaped plate is filtered, thereby reducing damage to the pump body. A spring pulls a retaining plate, causing the support shell to tightly contact the bottom of the outer casing. A sealing element is placed between the outer casing and the support shell, increasing the sealing between them and thus sealing the adapter pipe, air inlet pipe, support shell, and input end. Simultaneously, the retaining plate and spring work together to fix the support shell, increasing the structural stability of the equipment. Attached Figure Description

[0018] 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.

[0019] Example

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a rolling mill dust removal device, including a device shell 1, a fixed frame 2 fixedly connected to the bottom of the device shell 1, a sliding frame 3 slidably connected to the inner wall of the fixed frame 2, a support shell 4 fixedly connected to the bottom of the sliding frame 3, an arc plate 5 fixedly connected to the inner wall of the support shell 4, a transfer pipe 6 fixedly connected to the bottom of the device shell 1, an air inlet pipe 7 fixedly connected to the bottom of the transfer pipe 6, the other end of the transfer pipe 6 fixedly connected to the port of the dust suction end pipe of the device shell 1, an input end 8 fixedly connected to the bottom of the device shell 1, and a sliding connection between the support shell 4 and one side of the arc plate 5 and the outer surface of the transfer pipe 6.

[0021] In the above embodiments, the air inlet and input end 8 of the pump body in the outer casing 1 are fixedly connected, and the port on the outer casing 1 for dust suction is fixedly connected to the adapter pipe 6, thereby forming a flow structure. When the pump body is turned on, the gas at the port of the outer casing 1 passes through the adapter pipe 6, the air inlet pipe 7, the support shell 4, and the input end 8 to reach the pump body. Liquid is set inside the support shell 4 to absorb dust. The dust carried by the gas changes the gas flow direction through the arc plate 5 and then comes into contact with the liquid inside the support shell 4. Through the absorption of the liquid, the dust carried by the gas reaching the top of the arc plate 5 is filtered by the liquid, thereby reducing damage to the pump body.

[0022] Multiple fixing blocks 9 are fixedly connected to the bottom of the outer shell 1 of the device. A rotating plate 10 is rotatably connected between one side of each pair of fixing blocks 9. Rotating grooves 11 are opened on both sides of the rotating plate 10. A rotating rod 12 is rotatably connected to the inner wall of the rotating groove 11. One end of the rotating rod 12 is rotatably connected to one side of the fixing block 9.

[0023] A torsion spring 13 is provided on the outer surface of the rotating rod 12. One end of the torsion spring 13 is fixedly connected to one side of the fixing block 9, and the other end of the torsion spring 13 is fixedly connected to the inner wall of the rotating groove 11.

[0024] Through the above embodiments, the torsion spring 13 drives the rotating plate 10 to rotate toward the support shell 4, thereby enabling the clamping plate 15 to be tightly attached to the support shell 4.

[0025] The bottom of the rotating plate 10 is fixedly connected to the fixed shell 14, and the inner wall of the fixed shell 14 is slidably connected to the clamping plate 15;

[0026] A groove 16 is provided on the top of the card plate 15, and multiple telescopic rods 17 are fixedly connected to the inner wall of the groove 16. One end of the telescopic rod 17 is fixedly connected to the top of the fixed shell 14. A pull hole 19 is provided on one side of the card plate 15.

[0027] A spring 18 is provided on the outer surface of the telescopic rod 17. One end of the spring 18 is fixedly connected to the inner wall of the fixed shell 14, and the other end of the spring 18 is fixedly connected to the inner wall of the groove 16.

[0028] Through the above embodiments, the spring 18 pulls the clamping plate 15 to make the support shell 4 tightly contact the bottom of the device housing 1, and a sealing element is set between the device housing 1 and the support shell 4. At this time, the sealing between the device housing 1 and the support shell 4 can be increased, thereby sealing the connection pipe 6, the air inlet pipe 7, the support shell 4 and the input end 8. At the same time, the clamping plate 15 and the spring 18 work together to fix the support shell 4, increasing the structural stability of the equipment.

[0029] Working principle:

[0030] like Figure 1-4 As shown, during use, when the pump body is turned on, the gas at the port of the device housing 1 passes through the adapter pipe 6, the inlet pipe 7, the support housing 4, and the input end 8 to reach the pump body. Inside the support housing 4, liquid is placed to adsorb dust. The dust carried by the gas changes the direction of gas flow through the arc plate 5, and then comes into contact with the liquid inside the support housing 4. Through the adsorption of the liquid, the dust carried by the gas reaching the top of the arc plate 5 is filtered by the liquid. When disassembling, rotate the locking plate 15 to leave the support housing 4, so that the support housing 4 can be removed for cleaning. When installing, the support housing 4 drives the sliding frame 3 into the inner wall of the fixed frame 2, and then pull the pull hole 19 to drive the locking plate 15 to lock the support housing 4, thereby completing the installation.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
