Description
Technical field
The present invention relates to technology of instrument and meter field more particularly to a kind of dust-extraction units of instrument and meter.
Background technique
The inspection side of currently known power plant's pulverized coal bin coal dust generally uses hand shaken reel, the storage to convert in storehouse.This
Method need to be accomplished manually in working site.It is inefficient, it is unfavorable for the automatic control of power plant, some uses capacitor, and electronic type surpasses
Sound wave, radar, the detection such as laser, since temperature is high in pulverized coal bin, and dust dances in the air, and dust is liable to stick to the table of instrument and meter
Face causes the data of detection inaccurate, or even destroys instrument and meter.
Summary of the invention
The purpose of the present invention is to provide a kind of dust-extraction units of instrument and meter, solve the powder in pulverized coal bin in the prior art
The technical issues of dirt is liable to stick to the surface of instrument and meter, causes the data of detection inaccurate, or even destroys instrument and meter.
In order to solve the above-mentioned technical problem, the invention is realized by the following technical scheme:
A kind of dust-extraction unit of instrument and meter, including lead to vertical ventilation duct and loop vent pipe, loop vent pipe is arranged vertical
The lower end of ventilation duct, and be connected to vertical ventilation duct, instrument and meter fixing clamp and the first spray are provided on the vertical ventilation duct
Mouth, first jet are connected to vertical ventilation duct, are provided with multiple second nozzles on the loop vent pipe；Instrument and meter passes through solid
When clamp is fixed on dust-extraction unit, first jet is directed at the main body of instrument and meter, multiple second nozzle alignment instrument and meters
Test section.
When being detected using instrument and meter to pulverized coal bin, first instrument and meter is arranged by fixing clamp in dust-extraction unit
On, guarantee the test section of multiple second nozzle alignment instrument and meters, then blast pipe is connected to and is led to vertical ventilation duct
Wind then dispels the dust around the main body of instrument and meter from the gas sprayed in first jet, prevents dust from instrument and meter
The seam crossing of main body enters inside it, destroys instrument and meter, and the gas sprayed from multiple second nozzles dispels the inspection of instrument and meter
Dust around survey portion guarantees the accuracy of detection data.
It is further improved, two first jets is set on the vertical ventilation duct, are respectively aligned to the main body of instrument and meter
Different parts guarantee that the seam crossing of instrument and meter main body has nozzle alignment.
It is further improved, there are four second nozzles for setting on the loop vent pipe, by the quantity for increasing second nozzle
Guarantee blowing effect.
It is further improved, four second nozzles are uniformly arranged on loop vent pipe.
It is further improved, the second nozzle is winding to be converted into hook-type, and four second nozzles are towards loop vent pipe
Center.
It being further improved, the fixing clamp is clip, it is easy to operate, convenient for the dismounting of instrument and meter.
Compared with prior art, the beneficial effects of the present invention are:
When being detected using instrument and meter to pulverized coal bin, instrument and meter is arranged on dust-extraction unit by fixing clamp first, is protected
The test section for demonstrate,proving multiple second nozzle alignment instrument and meters, then blast pipe is connected to and is aerated with vertical ventilation duct, then
The dust around the main body of instrument and meter is dispelled from the gas sprayed in first jet, prevents dust from the main body of instrument and meter
Seam crossing enters inside it, destroys instrument and meter, and the gas sprayed from multiple second nozzles dispels the test section week of instrument and meter
The dust enclosed guarantees the accuracy of detection data.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the dust-extraction unit of instrument and meter of the present invention.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
To keep the purpose of the present invention and technical solution clearer, below in conjunction with the embodiment of the present invention to skill of the invention
Art scheme is clearly and completely described.
A kind of dust-extraction unit of instrument and meter as shown in Figure 1, 2, including lead to vertical ventilation duct 1 and loop vent pipe 2, annular
The lower end of vertical ventilation duct 1 is arranged in ventilation duct 2, and is connected to vertical ventilation duct 1, is arranged on the vertical ventilation duct 1 useful
In the fixing clamp 5 and first jet 3 of retainer instrument instrument, first jet 3 is connected to vertical ventilation duct 1, the loop vent pipe 2
On be provided with multiple second nozzles 4；When instrument and meter is fixed on dust-extraction unit by fixing clamp 5, first jet 3 is directed at instrument
The main body of instrument, multiple second nozzles 4 are directed at the test section of instrument and meter.
When being detected using instrument and meter to pulverized coal bin, first instrument and meter 6 is arranged by fixing clamp 5 in dust-extraction unit
On, guarantee that multiple second nozzles 4 are directed at the test section of instrument and meter, then blast pipe is connected to and is carried out with vertical ventilation duct 1
Ventilation, then from the dust around the main body that the gas sprayed in first jet 3 dispels instrument and meter 6, prevent dust from instrument instrument
The seam crossing of the main body of table enters inside it, destroys instrument and meter, and the gas sprayed from multiple second nozzles 4 dispels instrument and meter
Test section around dust, guarantee the accuracy of detection data.
In the present embodiment, two first jets 3 are set on the vertical ventilation duct, are respectively aligned to the main body of instrument and meter
