Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe pickling, and in particular relates to an acid mist discharge device for a steel pipe pickling tank. Background Art

[0002] Steel pipe pickling is a metal surface treatment process, the purpose of which is to remove impurities such as oxide scale, rust, oil, dust, etc. on the surface of the steel pipe to improve the corrosion resistance and surface quality of the steel pipe.

[0003] The existing acid mist discharge device for steel pipe pickling tank has some shortcomings when in use. The acid mist needs to be extracted when the steel pipe is pickled and when the pickling is completed to prevent the acid mist from overflowing to the outside. However, the exhaust volume required for steel pipe pickling is small, while the exhaust volume required for steel pipe discharge is large. The exhaust volume of the existing device cannot be changed. Multiple fans will consume a lot of electricity when running, which requires a lot of electricity bills. In addition, too much acid mist extracted during pickling may affect the pickling effect, resulting in incomplete pickling of the steel pipe. In view of this, we propose an acid mist discharge device for steel pipe pickling tank. Utility Model Content

[0004] The utility model aims to provide an acid mist discharge device for a steel pipe pickling tank to solve the problems raised in the above-mentioned background technology.

[0005] In view of this, the utility model provides an acid mist discharge device for a steel pipe pickling tank, comprising:

[0008] A plurality of lifting assemblies are respectively located in a plurality of pickling tank bodies and are respectively used to drive a plurality of sliding plates to lift and lower.

[0009] In the technical scheme, when the steel pipe is pickled, the fan will run at low power and extract the acid mist in the pickling tank body through the corresponding plurality of through holes and the plurality of suction pipes into the corresponding connecting pipe one, and then the acid mist in the plurality of connecting pipes one is discharged to the outside through the connecting pipe two and the ventilation pipe and finally through the air outlet pipe, so as to prevent the acid mist from overflowing to the outside during the pickling of the steel pipe;

[0010] When the pickling of the steel pipe in one of the pickling tank bodies is completed, the personnel increase the suction power of the fan, and then start the two motors on the corresponding pickling tank body. Through the set lifting assembly, the corresponding sliding plate can be driven to slide upward. When the sliding plate slides to the appropriate position, several through holes on the corresponding fixed plate can all inhale air. At this time, the acid mist in the corresponding pickling tank body will be absorbed by the stronger wind, which can prevent the acid mist in the corresponding pickling tank body from overflowing to the outside during discharging. Only one fan is set up to save costs and operating costs, and the air volume can be adjusted twice, which enhances the flexibility of the device when used.

[0014] In the present technical scheme, when the pickling of the steel pipe in one of the pickling tank bodies is completed, the personnel increase the suction power of the fan, and then start the two motors on the corresponding pickling tank body. The motor is powered on and drives the gear to rotate. The gear drives the rack meshing with it to slide. The rack drives the corresponding guide columns to slide upward through the corresponding inclined grooves. The upward sliding of the guide column drives the corresponding sliding plate to slide upward. When the sliding plate slides to a suitable position, the corresponding through holes on the fixed plate can all inhale air. At this time, the acid mist in the corresponding pickling tank body will be absorbed by the stronger wind, which can prevent the acid mist in the corresponding pickling tank body from overflowing to the outside when discharging.

[0021] In the above technical solution, further, one side of the sliding plate is in close contact with one side of the fixed plate.

[0022] In this technical solution, it is ensured that the sliding plate can close several through holes on the fixed plate.

[0023] The beneficial effects of the utility model are:

[0024] The acid mist discharge device for a steel pipe pickling tank has a low power fan that extracts the acid mist in the pickling tank body through a corresponding plurality of through holes and a plurality of air suction pipes into a corresponding connecting pipe one when the steel pipe is pickled. The acid mist in the connecting pipe one is then discharged to the outside through a connecting pipe two and a ventilation pipe and finally through an air outlet pipe, thereby preventing the acid mist from overflowing to the outside when the steel pipe is pickled.

[0025] When the pickling of the steel pipe in one of the pickling tank bodies is completed, the personnel increase the suction power of the fan, and then start the two motors on the corresponding pickling tank body. Through the set lifting assembly, the corresponding sliding plate can be driven to slide upward. When the sliding plate slides to the appropriate position, several through holes on the corresponding fixed plate can all inhale air.
