Description
Technical field
It the utility model is related to technology of instrument and meter field, more particularly to a kind of dust arrester of instrument and meter.
Background technology
The inspection side of currently known power plant's Pulverized Coal Bin coal dust, general to use 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 automatically controlling for power plant, some uses electric capacity, electronic type, surpassed
Sound wave, radar, laser etc. detect, and because 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, cause the data of detection to be forbidden, or even destroy instrument and meter.
Utility model content
The purpose of this utility model is to provide a kind of dust arrester of instrument and meter, solved in Pulverized Coal Bin in the prior art
Dust be liable to stick to the surface of instrument and meter, cause the data of detection to be forbidden, or even destroy the technical problem of instrument and meter.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
A kind of dust arrester of instrument and meter, including lead to vertical ventilation duct and loop vent pipe, loop vent pipe is arranged on
The lower end of vertical ventilation duct, and connect with vertical ventilation duct, it is described to be provided with instrument and meter geometrical clamp and the on ventilation duct vertically
One nozzle, first jet are connected with vertical ventilation duct, and multiple second nozzles are provided with the loop vent pipe；Instrument and meter leads to
When crossing geometrical clamp and being fixed on dust arrester, first jet is directed at the main body of instrument and meter, and multiple second nozzles are directed at instrument instrument
The test section of table.
When being detected using instrument and meter to Pulverized Coal Bin, instrument and meter is first arranged on dust arrester by geometrical clamp
On, ensure the test section of multiple second nozzle alignment instrument and meters, then blast pipe is connected and led to vertical ventilation duct
Wind, the then gas sprayed from first jet dispel the dust around the main body of instrument and meter, prevent 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, ensure the accuracy of detection data.
Further improve, two first jets are set on the vertical ventilation duct, are respectively aligned to the main body of instrument and meter
Different parts, ensureing the seam crossing of instrument and meter main body has nozzle alignment.
Further improve, four second nozzles are provided with the loop vent pipe, by the quantity for increasing second nozzle
Ensure blowing effect.
Further improve, four second nozzles are uniformly arranged on loop vent pipe.
Further improve, the second nozzle is winding to be converted into hook-type, and four second nozzles are towards loop vent pipe
Center.
Further improve, the geometrical clamp is clip, easy to operate, is easy to the dismounting of instrument and meter.
Compared with prior art, the beneficial effects of the utility model are：
When being detected using instrument and meter to Pulverized Coal Bin, instrument and meter is first arranged on dust arrester by geometrical clamp
On, ensure the test section of multiple second nozzle alignment instrument and meters, then blast pipe is connected and led to vertical ventilation duct
Wind, the then gas sprayed from first jet dispel the dust around the main body of instrument and meter, prevent 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, ensure the accuracy of detection data.
