Abstract
The utility model discloses a muffle furnace, which comprises a furnace body. A hearth is arranged inside the furnace body; insulating bricks are arranged around four walls of the hearth; heating elements are inlaid on two sides of the inner wall of the insulating bricks, so that heating wires of the heating elements are exposed in the hearth; the heating is quick; and the cooling is also quick, so that the temperature of the hearth can be controlled limitedly. The muffle furnace is industrial heating equipment which is simple in principle and high in heat efficiency.
Description
Technical field
The utility model belongs to Industrial Analysis and uses the roasting apparatus field, specifically refers to a kind of Muffle furnace.
Background technology
The main application of industry Muffle furnace is to the in addition part heating of raw material, blank, machinery for mechanical industry, so the control to temperature requires very high, according to furnace temperature to giving the deviation of fixed temperature, automatically be switched on or switched off the heat-source energy of supplying with stove, or continuously change the size of heat-source energy, furnace temperature is stabilized in the given temperature range, to satisfy the needs of Technology for Heating Processing.And existing Muffle furnace as shown in Figure 1: heating element heater is arranged on around the outer wall of insulating brick, and like this, Muffle furnace generates heat by heater element, transmitted by insulating brick, so that the temperature heating in the burner hearth is slow, it is also slow to lower the temperature, and can cause the temperature surveyed with thermocouple inconsistent.
The utility model content
The technical problems to be solved in the utility model provides the industry heating equipment that a kind of principle is simple, the thermal efficiency is high.
Muffle furnace described in the utility model comprises body of heater, is provided with burner hearth in the inside of body of heater, is provided with insulating brick around the wall of burner hearth, inlays heater element in the inwall both sides of insulating brick.
Logical structure during described insulating brick has.
The beneficial effects of the utility model are:
The utility model is installed in heater element in the insulating brick, so that the heater element heating wire exposes in burner hearth, heating is fast, and it is also fast to lower the temperature, and is heated evenly, so that fire box temperature can limitedly be controlled.Secondly, heating element heater is fully hidden in the insulating brick inwall, avoids contacting with gas corrodibility, steam etc., and has prolonged its service life.
Description of drawings
Fig. 1 is the structural representation of existing Muffle furnace.
Fig. 2 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 2, Muffle furnace described in the utility model comprises body of heater, is provided with burner hearth 4 in the inside of body of heater 1, is provided with insulating brick 2 around the wall of burner hearth 4, inlays heater element 3 in the inwall both sides of insulating brick 2.
The utility model compared with prior art, the utility model is installed in heater element 3 in the insulating brick, so that the heater element heating wire exposes in burner hearth 4, heating is fast, and it is also fast to lower the temperature, and is heated evenly, so that burner hearth 4 temperature can limitedly be controlled, the temperature of surveying with thermocouple differs less; Its heating element heater 3 is fully hidden in insulating brick 2 inwalls, avoids contacting with gas corrodibility, steam etc., and has prolonged its service life.
The utility model provides a kind of form and implementation method of Muffle furnace; the above only is preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
