Abstract

The utility model discloses a kind of Elema impurity collector, a kind of Elema impurity collector, including the nonmetallic high-temperature heating element being sintered into one by connection end and some Elemas, it is characterized in that the connection end of some Elema bottoms is provided with the impurity collector of sleeve structure, the impurity collector is the ash-storing bin of ship shape, it is the through hole being correspondingly arranged with Elema to be provided with it some, and impurity collector is inserted in Elema by through hole and is sleeved on connection end.The utility model has simple in construction compared with prior art, it is easy to use, effectively prevent the oxidation impurities of Elema from dropping in the raw material that bottom is heated, avoid Elema from producing the material for being oxidized or nitrogenizing in use to come off and cause the impurity of product to pollute, thoroughly solve the problem of Elema oxidation impurities influence on product quality for a long time, so that Elema can be run safely and effectively, cleanly under normal operating condition, product quality is improved, production cost is reduced.

Description

A kind of Elema impurity collector

Technical field

The utility model is related to silicon molybdenum or Globar heating element technical field, and specifically a kind of Elema impurity is received Storage.

Background technology

It with the green hexagonal carborundum of high-purity is primary raw material that Elema, which is, by certain material than processing base, through 2200 DEG C High temperature silication recrystallization sinters and bar-shaped, tubulose nonmetallic high-temperature electric heat element is made.It is normal in Elema oxidizing atmosphere Temperature in use is continuous using up to 2000 hours up to 1450 DEG C.Elema forms certain resistance according to different proportionings, leads to Generated heat after electricity, its surface temperature is higher, and Elema has good chemical stability, and capacity antacid is strong.

At present, some Elema parallel connections are one group of heating element heater, silicon typically all by connection end by Globar heating element Carbon-point generates heat after powered up, and alkaline matter has corrosion function to it under hot conditions, and Elema element is long-term more than 1000 DEG C Using following effect can occur with oxygen and vapor：

⑴ SiC+2O₂→Si O₂+CO₂ ⑵ SiC+4H₂O=Si O₂+4H₂+CO₂

Cause the SiO in heating element heater₂Content gradually increases, and resistance is slowly increased therewith, for it aging.Such as vapor mistake It is many, SiC can be promoted to aoxidize, the H produced is reacted by (2) formula₂With the O in air₂With reference to H₂O reacts generation vicious circle again, reduction Component life.Hydrogen (H₂) reduction of heating element heater mechanical strength can be made.Nitrogen (N₂) can prevent SiC from aoxidizing below 1200 DEG C, nitrogen Gas reacts more than 1350 DEG C with SiC, SiC is decomposited chlorine (Cl₂) SiC can be made to decompose completely.

The Globar heating element of prior art can produce the material for being oxidized or nitrogenizing and come off in use, come off Impurity directly drop bottom heat raw material in, cause impurity contaminated materials, have a strong impact on product quality.

Utility model content

The purpose of this utility model is in view of the shortcomings of the prior art and designs a kind of Elema impurity collector, using set Impurity collection structure on the connection end of Elema bottom so that the impurity that Elema comes off can directly be dropped in collector It is interior, pollution of the dropping to surrounding and bottom environment is effectively prevented, or even cause the damage of heated material so that Elema exists It can safely and effectively, cleanly be run under normal operating condition, not result in material-to-be-heated impurity pollution, and influence product matter Amount.

What the purpose of this utility model was realized in：A kind of Elema impurity collector, including by connection end with it is some The nonmetallic high-temperature heating element that Elema is sintered into one, is characterized in the connection end of some Elema bottoms provided with suit The impurity collector of structure, the impurity collector is the ash-storing bin of ship shape, and its interior is provided with some is to be correspondingly arranged with Elema Through hole, impurity collector is inserted in Elema by through hole and is sleeved on connection end.

The projected area of the impurity collector is more than connection end and the connection plane of some Elemas.

The utility model is easy to use compared with prior art with simple in construction, effectively prevents that the oxidation of Elema is miscellaneous Matter is dropped in the raw material of bottom heating, the Elema impurity periodic cleaning in collector come off, it is to avoid Elema makes The contamination of products for producing oxidized or coming off for nitridation materia during and causing, thoroughly solves Elema oxygen for a long time Change the problem of Impurities Upon Product Quality influences so that Elema can be run safely and effectively, cleanly under normal operating condition, be carried High yield quality, reduces production cost.

Embodiment

Refering to 1~accompanying drawing of accompanying drawing 3, the utility model is sintered into one by connection end 3 with three Elemas 1, composition it is non- Metallic high temperature heating element heater, the connection end 3 of some bottoms of Elema 1 is provided with the impurity collector 2 of sleeve structure；It is described Impurity collector 2 is inserted in Elema 1 by through hole 6, and impurity collector 2 is sleeved on into the special oxygen for collecting Elema 1 on connection end 3 Change cast.

Refering to accompanying drawing 4, the impurity collector 2 is the ash-storing bin of ship shape, and its interior is provided with some is corresponding set with Elema 1 The through hole 6 put；The projected area of the impurity collector 2 is more than connection end 3 and the connection plane of some Elemas 1.

Refering to accompanying drawing 5, the utility model is arranged in glass kiln, Elema 1 generates heat after powered up, heats its underpart Frit, because under the high temperature conditions, Elema 1 is had an effect with oxygen and vapor in use, can be produced It is oxidized or the impurity 5 of nitridation comes off, the impurity 5 come off is directly dropped in the impurity collector 2 of the bottom of Elema 1, very well Prevent the oxide of Elema 1 to be dropped in heating raw materials to pollute and influence product quality.The utility model is to non- The structure of metallic high temperature heating element heater does not change, and Elema 1 is possible in use simply by impurity collector 2 The position of drippage carries out impurity collection.Impurity collector 2 uses a kind of resistant to elevated temperatures material, such as ceramics, mullite, quartz, carbon Sintered after the high-temperature insulation materials such as SiClx, molybdenum SiClx, refractory material, magnesia, boron nitride, moulding through particular mold shape Shaping.

The utility model in its proper site to heating element heaters such as various Elemas, Si-Mo rods by setting sleeve structure Impurity collector so that impurity that this kind of calandria is produced in use etc. is effectively collected, in order to avoid have influence on week Collarette border and the quality of heating object.Simply the utility model is further described above, and it is originally special to be not used to limitation Profit, all is the utility model equivalence enforcement, is intended to be limited solely by within the right of this patent.
