Description

Technical Field

[0001] The utility model relates to the field of dust removal, in particular to dust removal equipment used in the production of seamless steel pipes. Background Art

[0002] In seamless steel pipe production enterprises, the processing process includes: billet preparation, heating, perforation, continuous rolling mill, reheating, sizing mill, marking, manual inspection, non-destructive testing, straightening, pipe cutting, etc. The main smoke and dust generated are in the perforation, borax, continuous rolling mill front desk, continuous rolling mill, tube stripping machine and sizing mill. A large amount of smoke and dust are generated; among these pollution points, the front desk of the continuous rolling mill produces the most smoke, dust and water vapor, which pollutes the work and surrounding environment. Operators need to check frequently. If inhaled by workers, it will cause various occupational diseases.

[0003] In the prior art, there is a dust removal equipment for seamless steel pipe production with application number CN202120131230.7. In the above scheme, "when the dust removal equipment is working normally, the smoke and dust generated by the seamless steel pipe below are captured and collected by the upper suction hood, passed through the air outlet pipe, entered the dust removal duct, and then filtered and separated by the dust collector, and finally discharged through the fan." However, the size of the seamless steel pipe will be different. When producing larger seamless steel pipes, the starting height of the smoke is higher, which is convenient for inhalation through the suction hood. However, when inhaling the smoke generated by the small seamless steel pipe, there is a distance between the smaller seamless steel pipe and the suction hood. The smoke will drift around, resulting in less smoke inhaled by the suction hood, which is not convenient for increasing the amount of smoke inhaled by the suction hood and reducing the amount of smoke floating out. It is not convenient to adjust the distance between the suction nozzle of the suction hood and the seamless steel pipe according to the size of the seamless steel pipe to reduce the amount of smoke floating out. How to invent a dust removal equipment for seamless steel pipe production to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

The other end of the fixed pipe 312 is connected to the air intake hopper 313. The air intake hopper 313 is used to cooperate with the suction mechanism 200 to suck the smoke below.

[0025] See also Figures 2 to 4 The adjusting member 320 is connected to the fixed pipe 312 and the air intake hopper 313 through the first connecting pipe 321 and the second connecting pipe 322. The air intake hopper 313 is provided in two halves, which are respectively fixedly connected to the first connecting pipe 321 and the second connecting pipe 322. The first connecting pipe 321 and the second connecting pipe 322 are sealed and sleeved on the bottom of the fixed pipe 312 through the connecting plate 323 and the two-way cylinder 324. The first connecting pipe 321 and the second connecting pipe 322 are fixedly connected to drive the air intake hopper 313 to fit and separate.

[0026] Both sides of the first connecting tube 321 and the second connecting tube 322 are fixedly connected to the connecting plates 323, and the two connecting plates 323 are fixedly connected by the two-way cylinders 324. The two two-way cylinders 324 squeeze the connecting plates 323 on both sides of the two-way cylinders 324 to expand the first connecting tube 321 and the second connecting tube 322 away from the side wall of the fixed tube 312 for convenient height adjustment. The two sides of the two connecting plates 323 are penetrated by the sliding limit connection limit rod 325, and the two ends of the limit rod 325 are limited by the second spring 326 located on the back of the connecting plate 323. The limit rod 325 is used to limit the linear motion when the two-way cylinder 324 drives the connecting plate 323 to expand or contract, and cooperate with the second spring 326 to squeeze the two connecting plates 323 to facilitate the first connecting tube 321 and the second connecting tube 322 to be close to each other. A rubber pad is provided between the first connecting tube 321 and the second connecting tube 322 for convenient sealing connection.

[0027] The fixed tube 312 is externally fixedly sleeved with a plurality of limiting hoops 314, and the bottom of the fixed tube 312 is provided with an outer edge, and the limiting hoops 314 are used to prevent the first connecting tube 321 and the second connecting tube 322 from falling off due to insufficient connection. A second limiting ring 328 is provided at the top of the first connecting tube 321, and a first limiting ring 327 is provided at the top of the second connecting tube 322. The connection between the second limiting ring 328 and the first limiting ring 327 is a step setting, and the inner walls of the second limiting ring 328 and the first limiting ring 327 are provided with rubber sealing pads to increase the sealing effect and the fixed connection effect. A connecting rod 315 is slidably connected between the two sides of the air intake hopper 313, and the first springs 316 are sleeved on both ends of the connecting rod 315. The connecting rod 315 is used to horizontally move the two halves of the air intake hopper 313 when limiting the air intake hopper 313. The first spring 316 is used to make the two halves of the air intake hopper 313 have a force to move closer. Rubber pads are provided between the two halves of the air intake hopper 313 to facilitate sealing connection.

[0028] See also Figure 2 and Figure 4 The lifting member 330 is fixedly connected to the two bidirectional cylinders 324 through a connecting block, and the other end of the lifting member 330 is connected to the bottom of the suction mechanism 200. The lifting member 330 drives the adjusting member 320 to adjust the length of the connecting member 310 to facilitate the suction of smoke and dust.

[0029] Working principle: The suction mechanism 200 sucks in the smoke and dust below through the first connecting pipe 321 of the air intake hopper 313 and the fixed pipe 312. When it is necessary to adjust the height of the air intake hopper 313, the two-way cylinder 324 drives the first connecting pipe 321 and the second connecting pipe 322 to expand to both sides and drives the air intake hopper 313 to separate to both sides. The two two-way cylinders 324 are pulled by the lifting member 330 to adjust the height. When the position is correct, the two-way cylinder 324 is controlled to drive the connecting plate 323 to make the first connecting pipe 321 and the second connecting pipe 322 close to the outer wall of the fixed pipe 312 to cooperate with the first limiting ring 327 and the second limiting ring 328 to seal and connect.
