Abstract
The utility model relates to a kind of sampling feeler lever of gas analyzer, it is made up of stainless-steel tube, stainless steel packing ring, stainless steel equal angle and solid wear resistant structure, this stainless-steel tube truncation end and stainless steel packing ring centering weld together, solid wear resistant structure then uniform filling is pressed in stainless steel equal angle interior angle, solid wear resistant structure is then close to by stainless-steel tube, and stainless steel equal angle truncation end and stainless steel packing ring weld together.Have and reduce fault and labour cost, utilize resource to greatest extent, solve former sampling the feeler lever easily worn out or technological deficiency that rubs simultaneously, extend the feature in its serviceable life widely.
Description
Technical field
The utility model belongs to gas analyzer on-line detecting system sampler technical field, relates to a kind of sampling feeler lever of gas analyzer.
Background technology
At present, in the survey coal pulverizer exit gas oxygen content sampling of our factory's ironmaking coal-grinding operation, all stretch in technique pulverized coal channel with sampling feeler lever and sample.Known sampling feeler lever is that straight-bar is one-piece type, and its structure is connected to form by shaft (connector) and steel washer.During sampling, clamp steel washer with flange, shaft is inserted in pulverized coal channel, extract the gas in pipeline.Shaft is that the stainless-steel tube of Φ 25 is made, because in coal pulverizer outlet conduit being the fluid that swiftly flowing gas and coal dust mix, fluid high-speed washes away feeler lever shaft, cause coal dust shaft face of polishing easily worn out or rub, make be full of coal dust in sampling feeler lever and block, therefore analyser Frequent Troubles, feeler lever within 2 ~ 3 months, will be changed, from production safety and alleviate labour's angle consider, must extend sampling feeler lever serviceable life.See Fig. 1, former sampling feeler lever is made up of stainless-steel tube 1 and stainless steel packing ring 2, and stainless-steel tube 1 tube wall that former sampling feeler lever stretches into coal pulverizer outlet conduit is thin, easily worn out or rub, and sampling feeler lever is blocked.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of sampling feeler lever of gas analyzer, that reduces fault and labour cost, utilizes resource to greatest extent, solve former sampling the feeler lever easily worn out or technological deficiency that rubs simultaneously, extend its serviceable life widely.
The utility model solves the technical scheme that its technical matters adopts: a kind of sampling feeler lever of gas analyzer, it is made up of stainless-steel tube, stainless steel packing ring, stainless steel equal angle and solid wear resistant structure, this stainless-steel tube truncation end and stainless steel packing ring centering weld together, solid wear resistant structure then uniform filling is pressed in stainless steel equal angle interior angle, solid wear resistant structure is then close to by stainless-steel tube, and stainless steel equal angle truncation end and stainless steel packing ring weld together.
The length of described stainless-steel tube is 100 centimetres, and specification is Φ 20*4, and this stainless-steel tube one end is truncation, and the other end is oblique 45
ocut.
The length of described stainless steel equal angle is 101 centimetres, specification ∠ 30*2.5, this one end truncation, the other end oblique 45
ocut.
The inner ring diameter of described packing ring is 33 millimeters, and race diameter is 108 millimeters, and thickness is 10 millimeters.
Described solid wear resistant structure filling length is identical with angle steel length.
Described solid wear resistant structure is made up of emery, epoxide resin and hardening agent.
The beneficial effects of the utility model are: stainless steel angle steel face is for being subject to buffed surface, angle steel right angle just to pulverized coal flow to, right-angle surface is less than the surface of contact of semi circular surface, and right-angle surface can shunt coal dust fluid, feeler lever lifting surface area is reduced greatly, thus increase the feeler lever life-span, have and reduce fault and labour cost, utilize resource to greatest extent, solve former sampling the feeler lever easily worn out or technological deficiency that rubs simultaneously, extend the feature in its serviceable life widely.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See Fig. 2 ~ Fig. 5, a kind of sampling feeler lever of gas analyzer, it is made up of stainless-steel tube 1, stainless steel packing ring 2, stainless steel equal angle 3 and solid wear resistant structure 4, the length of stainless-steel tube 1 is 100 centimetres, specification is Φ 20*4, and this stainless-steel tube 1 one end is truncation, and the other end is oblique 45
ocut, this stainless-steel tube 1 truncation end and stainless steel packing ring 2 centering weld together, the inner ring diameter of stainless steel packing ring is 33 millimeters, race diameter is 108 millimeters, thickness is 10 millimeters, solid wear resistant structure 4 is by emery, epoxide resin and hardening agent are formed, this solid wear resistant structure 4 uniform fillings are pressed in stainless steel equal angle 3 interior angle, it is identical with angle steel length that solid wear resistant structure 4 fills length, solid wear resistant structure 4 is close to by stainless-steel tube 1, stainless steel equal angle 3 truncation end and stainless steel packing ring 2 weld together, the length of this stainless steel equal angle 3 is 101 centimetres, specification ∠ 30*2.5, this one end truncation, the other end oblique 45
ocut.
During sampling, clamp steel washer with flange, feeler lever oblique 45 will be sampled
ocutting end inserts in coal pulverizer outlet conduit, extracts the gas in pipeline.
The utility model stainless steel angle steel face is for being subject to buffed surface, angle steel right angle just to pulverized coal flow to, right-angle surface is less than the surface of contact of semi circular surface, and right-angle surface can shunt coal dust fluid, feeler lever lifting surface area is reduced greatly, thus increase the feeler lever life-span, have and reduce fault and labour cost, utilize resource to greatest extent, solve former sampling the feeler lever easily worn out or technological deficiency that rubs simultaneously, extend the feature in its serviceable life widely.
