The invention discloses a box-type assay furnace which comprises a furnace shell, a combustion chamber body, a furnace head and a furnace door. The combustion chamber body is arranged inside the furnace shell. A furnace lining is arranged on the inner wall of the furnace shell. A combustion chamber is defined inside the combustion chamber body. The front end of the combustion chamber body is opened. The furnace head and the front end of the combustion chamber body are connected so as to seal the front end of the combustion chamber body. A furnace opening is formed in the furnace head. The furnace door used for opening and closing the furnace opening is arranged on the furnace shell. The rear wall and the top wall of the combustion chamber body are provided with an exhaust hole and a thermocouple jack. A plurality of heaters extending into the combustion chamber are arranged on the left side and the right side of the top wall of the combustion chamber body. The box-type assay furnace has the advantages of being rapid in temperature rise, low in energy consumption, small in shell, low in weight and accurate in control.
Description
Technical field
The invention belongs to a kind ofly for measuring the device of material rare precious metal content, relate in particular to a kind of box assay furnace.
Background technology
For the material of measuring rare metal material or containing rare metal, the concentrate such as such as gold, silver, copper, lead, zinc, conventionally material need to be melted in assay furnace, rare precious metal in boring with enrichment, then carry out coolingly from taking out material in assay furnace, more cooled material is carried out to the mensuration of rare precious metal content.Traditional assay furnace comprises furnace shell, is arranged on hearth body and furnace lining in furnace shell, the monolithic construction that described burner hearth generally adopts aluminium oxide or carborundum to make, what furnace lining conventionally adopted is refractory brick or the structure of being combined with perlite, although traditional assay furnace is sturdy and durable, but intensification is slow, heat insulating ability is poor, energy consumption is high, and volume is larger, be not easy to mobile; In addition, the heating element heater arranging in burner hearth is perishable, need to often safeguard.
Summary of the invention
In order to address the above problem, the object of this invention is to provide a kind of box assay furnace, there is quick heating, energy consumption is low, housing is little, lightweight, controls accurate advantage.
In order to realize foregoing invention object, the present invention adopts technical scheme as described below:
A kind of box assay furnace, comprise furnace shell, be arranged on the hearth body in furnace shell, burner and fire door, furnace shell inwall is provided with furnace lining, described hearth body inside is limited with burner hearth, the front end of hearth body opens wide, described burner is connected to seal described hearth body front end and burner with the front end of hearth body are formed with fire door, on described furnace shell, be provided with the fire door for opening and closing described fire door, on the rear wall of described hearth body and roof, be respectively equipped with steam vent and thermocouple jack, a left side on the roof of hearth body, right both sides are provided with several and extend into the heater in burner hearth.
Further, the bottom of described burner hearth is provided with drop-bottom.
Further, the arranged on left and right sides of described hearth body inside all arranges a dividing plate, and the heater of both sides is corresponding between the left and right sidewall of dividing plate and hearth body respectively.
Further, described hearth body is spliced the integrative-structure forming by ceramic beaverboard.
Further, described heater is the globar of " U " font.
Further, between described furnace shell bottom and hearth body, be provided with refractory brick.
Further, described furnace shell is arranged on the movable supporting frame of foot wheel.
Owing to adopting technique scheme, the present invention has following superiority:
This box assay furnace has quick heating, energy consumption is low, efficiency is high, and housing is little, lightweight, controls the features such as accurate.Make it relatively traditional assay furnace overall weight and be reduced by least more than 50%, energy saving is more than 30%, and empty stove heating rate is enhanced about more than once, and reduces cost, enhances productivity, and mobile carrying is more light, is practically applicable to laboratory environment.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
In conjunction with Fig. 1-Fig. 4, a kind of box assay furnace, comprises furnace shell 1, is arranged on hearth body 7, burner and fire door 2 in furnace shell 1, is laid with the furnace lining 4 that adopts fibrofelt and cellucotton to make on furnace shell 1 inwall, is conducive to the insulation to hearth body 7; Described hearth body 7 inside are limited with burner hearth, the front end of hearth body 7 opens wide, described burner is connected to seal described hearth body 7 front end and burner with the front end of hearth body 7 are formed with fire door, on described furnace shell 1, be provided with the fire door 2 for opening and closing described fire door, poorly sealed for preventing fire door 2, cause fire door distortion, the pattern that fire door 2 adopts rotation side to open, without switch gate dead angle, ensure the sealing of hearth body 7; On the rear wall of described hearth body 7 and roof, be respectively equipped with steam vent 10 and thermocouple jack 6, the arranged on left and right sides on the roof of hearth body 7 is provided with several and extend into the heater 5 in burner hearth, and described heater 5 is U-shaped globar.
Preferably, described furnace shell 1 adopts sheet metal to make through this part welding processing, has strengthened on the one hand the bulk strength of this box assay furnace, and on the other hand, the housing of having abandoned traditional assay furnace adopts the structure of section steel manufacture, has greatly alleviated case weight.
Described hearth body 7 is the integrative-structures that adopt ceramic beaverboard splicing composition, adopts stepped sealedly between adjacent wall, and entirety is spacing, is conducive to reduce deflection and the amount of moving in the burner hearth course of work.
The drop-bottom 11 of silicon carbide material is set for load-bearing material in the bottom of burner hearth; in addition; between the bottom of furnace shell 1 and hearth body 7, refractory brick 8 is set; for supporting the bottom of hearth body 7; the weight of the material of placing on drop-bottom 11 is born by refractory brick 8, and protective effect has been played in the bottom of hearth body 7.
The roof of described hearth body 7 is by 50mm and the thick vertical overall structure spreading of ceramic beaverboard each interval of 80mm, and is equipped with high-temperature ceramic in this overall structure, strengthens roof intensity, prevents from caving in.
The arranged on left and right sides of described hearth body 7 inside all arranges a dividing plate 9; and the heater 5 of both sides is corresponding between dividing plate 9 and the left and right sidewall of hearth body 7 respectively; the setting of dividing plate 9 is to prevent from being corroded for the protection of heater 5, reduces the maintenance times of heater 5.
Described furnace shell 1 is arranged on the movable supporting frame 3 of foot wheel, can move with movable supporting frame 3, bottom at movable supporting frame 3 is provided with castor, the shortcoming of having avoided thus traditional assay furnace to need a dead lift or fork truck or crane to move in the time of transport, secondly,, in the time safeguarding assay furnace, do not need it to shift out from fixing workbench, can be directly right removable monkey man can achieve the goal, and makes operation easier easily.
