Abstract
The invention relates to a metallurgical device, in particular to a converter blowing noise collection protecting device which comprises a directional noise collecting pipe installation cavity arranged on a converter side wall fire barrier. The converter blowing noise collection protecting device is characterized in that a circulation water cooling cavity wraps the directional noise collecting pipe installation cavity, a noise collector is arranged in the directional noise collecting pipe installation cavity, a dust blowing guide pipe is communicated with the inside of the directional noise collecting pipe installation cavity, the dust blowing guide pipe is communicated with a nitrogen filter through an electromagnetic valve, and a sealing cover is arranged at one end of the directional noise collecting pipe installation cavity. The converter blowing noise collection protecting device is simple in structure, reasonable in design and flexible in application, it is guaranteed that the noise collector can stably and reliably collect converter blowing noise for a long time at a high-temperature dust environment, and manual on-site cleaning and maintaining workload is reduced.
Description
(1) technical field
The present invention relates to a kind of metallurgy equipment, particularly a kind of noise gathering protective device of bessemerizing.
(2) background technology
In steelmaking process; because misoperation often spitting and getting dry can occur; the generation of spitting and getting dry is mainly the change slag situation of not controlling well in stove; judgement stove internalization slag situation can be carried out indirect reaction according to the size of noise in stove; therefore gather accurately and reliably the generation of the minimizing spitting and getting dry that noise while bessemerizing just can be to a certain degree, thereby save energy and reduce the cost.
Very severe of pneumatic steelmaking site environment, when blowing, converter ambient temperature is high, dust is many, the blowing noise that accurately and reliably collect in the process of bessemerizing for a long time very difficult.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, provide a kind of gather accurately and reliably noise, manual maintenance amount little bessemerize noise gathering protective device.
The present invention is achieved through the following technical solutions:
A kind of noise gathering protective device of bessemerizing; comprise that the orientation being arranged on converter sidewall firebreak adopts sound pipe installation cavity; it is characterized in that: described orientation is adopted sound pipe installation cavity and is wrapped with circulating water chamber; orientation is adopted to be placed with in sound pipe installation cavity and is adopted sound device and internal communication has dust to purge guide pipe; dust purges guide pipe and is communicated with nitrogen filtering device by solenoid valve, and orientation is adopted sound pipe installation cavity termination and is provided with gland bonnet.
The present invention guarantees the directed temperature in sound pipe installation cavity of adopting by circulating water chamber, by dust blow device, guarantees the directed cleanliness factor in sound pipe installation cavity of adopting; Dust blow device purges guide pipe by nitrogen filtering device, solenoid valve and dust and is connected in series, by the break-make of solenoid control nitrogen.
More excellent scheme of the present invention is:
Described circulating water is provided with cooling water inlet pipe and cooling water outlet pipe on chamber, and chilled water thermometric detecting sensor is installed in circulating water chamber.
The described sound device of adopting connects sound analyzer or computing machine by cable.
Device of the present invention is comprised of three parts: water cooling unit, dust blow device, temperature measurement device.Water cooling unit comprises: gland bonnet, circulating water chamber, cooling water outlet pipe, cooling water inlet pipe, orientation are adopted sound pipe installation cavity; Dust blow device comprises: nitrogen filtering device, solenoid valve, dust purge guide pipe; Temperature measurement device comprises: cooling water temperature detecting sensor.
By adopting sound device, be placed on orientation and adopt in sound pipe installation cavity, by recirculated water, kept adopting sound device ambient temperature within adopting the suitable working temperature of sound device, and recirculated water occur to stop up or can detect by the cooling water temperature detecting sensor of top when not enough, thereby avoid causing high temperature to cause adopting sound tube failure because chilled water loses efficacy.In blowing gap, can control nitrogen solenoid valve while not gathering sound and purge, avoid orientation to adopt the dust accumulation of sound pipe installation cavity and affect the accuracy of sound.
The present invention is simple in structure, reasonable in design, and applying flexible can guarantee to adopt sound device and reliablely and stablely gather and bessemerize noise for a long time in many powder of high temperature environment, reduces artificial on-the-spot cleaning maintenance.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is structural representation of the present invention.
In figure, 1 nitrogen filtering device, 2 solenoid valves, 3 gland bonnets, 4 circulating water chambeies, 5 dusts purge guide pipe, 6 cooling water outlet pipes, 7 cooling water inlet pipes, 8 orientations are adopted sound pipe installation cavity, 9 chilled water thermometric detecting sensors.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises that the orientation being arranged on converter sidewall firebreak adopts sound pipe installation cavity 8, described orientation is adopted sound pipe installation cavity 8 and is wrapped with circulating water chamber 4, orientation is adopted to be placed with in sound pipe installation cavity 8 and is adopted sound device and internal communication has dust to purge guide pipe 5, dust purges guide pipe 5 and is communicated with nitrogen filtering device 1 by solenoid valve 2, and orientation is adopted sound pipe installation cavity 8 terminations and is provided with gland bonnet 3; On described circulating water chamber 4, be provided with cooling water inlet pipe 7 and cooling water outlet pipe 6, and chilled water thermometric detecting sensor 9 is installed in circulating water chamber 4; The described sound device of adopting connects sound analyzer or computing machine by cable.
Whole device is arranged on converter sidewall firebreak, and high pressure nitrogen is accessed to nitrogen filtering device 1 entrance, adopts sound device and is placed on orientation and adopts in sound pipe installation cavity 8, chilled water water inlet access cooling water inlet pipe 7, chilled water water outlet access cooling water outlet pipe 6.
Nitrogen filtering device 1, solenoid valve 2, dust purge guide pipe 5 and are connected in series, and control the directed dust of adopting in sound pipe installation cavity 8 purge action by solenoid valve 2; The cooling water temperature that cooling water temperature detecting sensor 9 detects in circulating water chamber 4; Adopt sound device and adopt by orientation the blowing noise that sound pipe installation cavity 8 gathers converter; What gland bonnet 3 prevented that external sound from entering that orientation adopts sound pipe installation cavity 8 adopts sound device.
The voice signal of adopting the collection of sound device can send sound analyzer to by cable or computing machine carries out analyzing and processing.
