Abstract
The invention discloses an all-fiber pit type crucible melting furnace. The all-fiber pit type crucible melting furnace comprises a furnace body, a furnace liner, a crucible and heating elements, wherein the furnace liner, the crucible and the heating elements are all located at the inner part of the furnace body; the furnace body consists of an upper furnace body and a lower furnace body which are connected together; the furnace liner is formed by splicing fiber modules, and the fiber modules are tightly attached to the inner wall of the furnace body; the heating elements are fixedly connected to the inner wall of the furnace liner; a discharge tube which is communicated with the outside world is arranged at the bottom of the crucible. The furnace liner of the all-fiber pit type crucible melting furnace adopts aluminium silicate fiber modules, and due to the small heat capacity and the small density of the aluminium silicate fiber modules, the temperature rise rate can be improved, and further the production efficiency is improved; in addition, an insulating layer is thinned, so that the furnace is lighter and convenient to move.
Description
Technical field
The invention belongs to the special equipment of a kind of smelting aluminium alloy, zinc and copper, relate in particular to a kind of full fiber well formula crucible melting stove
Background technology
At present, known well formula crucible melting stove is all to be combined by body of heater, furnace lining, heating element heater, crucible, conventionally, the general employing of traditional well formula crucible melting stove adds element device together with furnace lining pouring material, or is placed on and puts on a brick, and furnace lining generally is refractory brick, thereby, the Thickness Ratio of furnace lining is thicker, causes in heating process thermal losses larger, causes the waste of the energy.In addition, heating element heater mostly is resistance wire side and puts on a brick or be embedded in burner hearth insulation material at burner hearth, this setting cause in routine work, safeguard inconvenience and also cost higher.And well formula crucible furnace is top discharge mode conventionally, is unfavorable for using and the control to high temperature metal solution use procedure of some special occasions.
Summary of the invention
In order to address the above problem, the object of this invention is to provide a kind of full fiber well formula crucible melting stove, can overcome the heaviness of conventional well formula crucible melting stove, the defect such as heating rate is slow.
A kind of full fiber well formula crucible melting stove, comprise body of heater, furnace lining, crucible and heating element heater, furnace lining, crucible and heating element heater are all positioned at body of heater inside, described body of heater is linked together and is formed by upper furnace body and lower furnace body, described furnace lining is spliced by fiber chunk, fiber chunk is close on the inwall of body of heater, and described heating element heater is fixedly connected on the inwall of furnace lining, and the bottom of described crucible is provided with the drainage conduit being in communication with the outside.
Further, between described upper furnace body and lower furnace body, be provided with fiber sheet.
Further, be provided with relief hole on lower furnace body, described drainage conduit is stretched out relief hole and is in communication with the outside.
Further, on described furnace lining, be equipped with stainless steel lag screws, and stainless steel lag screws is welded on body of heater.
Further, described heating element heater is resistive band.
Further, described fiber chunk adopts alumina silicate fibre blanket compacting to form.
Owing to adopting technique scheme, the present invention has following superiority:
1, this full fiber well formula crucible melting stove, furnace lining adopts alumina silicate fibre block, because the little density of its thermal capacitance is little, can improve heating rate, and then improve production efficiency, and attenuate heat-insulation layer, stove is moved more light;
2, body of heater adopts upper and lower docking structure, and in the bottom of crucible, discharge nozzle is set, and makes feeding more convenient, when having avoided feeding tilting furnace, prevent dropping out of body of heater internal heating element, be convenient to safeguard and maintenance.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
As shown in Figure 1, 2, 3, a kind of full fiber well formula crucible 6 melting furnaces, comprise body of heater 1, furnace lining 2, crucible 6 and heating element heater 3, furnace lining 2, crucible 6 and heating element heater 3 are all positioned at body of heater 1 inside, described body of heater 1 is linked together and is formed by upper furnace body 1 and lower furnace body 1, and it is heat insulation between upper lower furnace body 1, fiber sheet to be set, so that the picking and placeing of crucible 6; Described furnace lining 2 is spliced by fiber chunk, and fiber chunk is close on the inwall of body of heater 1, and described heating element heater 3 is fixedly connected on the inwall of furnace lining 2, and heating element heater 3 is resistive band; The bottom of described crucible 6 is provided with the drainage conduit 7 being in communication with the outside.
On described lower furnace body 1, be provided with relief hole, described drainage conduit 7 is stretched out relief hole and is in communication with the outside.
On described furnace lining 2, be equipped with stainless steel lag screws 4, and stainless steel lag screws 4 is welded on body of heater 1, makes furnace lining 2 and body of heater 1 form overall structure, can prevent from that furnace lining 2 is long-term use and produce loosening.
In body of heater 1 inside, be provided with drainage conduit 7 heaters, and be positioned at drainage conduit 7 belows, can prevent the too low material frozen plug drainage conduit 7 that causes of discharge gate 5 temperature.
Described furnace lining 2 adopts some alumina silicate fiber felt chunks to be spliced, and alumina silicate fiber felt compression 60% is used further to splicing, utilizes its dilatancy feature, make between chunk contact fully and with body of heater 1 between be closely connected, improve heat insulation effect, prevented scattering and disappearing of body of heater 1 interior heat.
Described upper and lower body of heater 1 all adopts cold-rolled steel sheet one-shot forming, at the upper and lower end of upper furnace body 1 and the upper end of lower furnace body 1 difference welded flange, between upper and lower body of heater 1, by flange, links together; Body of heater 1 adopts the split-type structural of upper and lower body of heater 1, when having avoided feeding body of heater 1 tilt, prevent dropping out of body of heater 1 internal heating element 3, be convenient to safeguard and maintenance.
Described drainage conduit 7, when specifically installing and using, is connected with other output channel, and consumption is controlled, is convenient to the use of high temperature metal solution to control.
