Not only need to discharge substantial amounts of SO2、CO2Deng also continuously providing fresh air into burner hearth to meet the need to oxygen
Ask, otherwise oxidation is difficult to smoothly lasting carry out.Meanwhile under hot conditions, air is significantly expanded and thinned out in burner hearth, row
Though burner hearth is in communication with the outside by smoke pipe, fail to form effective circuit of air circulation, material is aoxidized slowly and do not filled in burner hearth
Point.
At the same time Muffle furnace as high-temperature heating equipment it is essential that its cooling structure, the Muffle furnace steelframe being currently known
The type of cooling of main body is air cooling, i.e., air cooling air passage, this side are served as while serving as Muffle furnace steelframe body pillar by square steel tube
The shortcomings that formula is：1. cooling effect is not ideal enough；2. it is compressed air to cool down medium use, noise is larger, be easy to cause noise
Pollution, it is unfavorable to working environment；3. cooling air channel is single, and Muffle furnace steelframe temperature is higher during normal work, so easily makes
It is larger into inlet end and the outlet side temperature difference, weigh to the inhomogeneous cooling of steelframe main body.
Utility model content
Technical problem to be solved in the utility model, which is to provide one kind and can continue oxygenating, makes oxidizing roasting more rapidly fill
Point, the water-cooled Muffle furnace that the structure that can effectively reduce Muffle furnace spin manifold temperature is simple, the thermal efficiency is high.
The utility model is that technical solution is used by solving its technical problem：
A kind of water-cooled Muffle furnace, including furnace body and burner hearth, furnace body include the steel structure frame being made of square steel tube, steel knot
Cooling device is equipped with structure frame, top is equipped with smoke exhaust pipe, and bottom is equipped with the air inlet pipe connected with burner hearth；Four wall of burner hearth is set
There is flame retardant coating, insulating layer is equipped between flame retardant coating and furnace body, inboard wall of burner hearth surface is equipped with heating element.
Further, cooling device is places water cold sleeve in the square steel tube of steel structure frame, the water inlet of casing and
Water outlet is stretched out outside frame, and cold water is flowed into from water inlet, water outlet outflow, in the gap that water cold sleeve and square steel tube are formed
Filled with heat conductive filler.
Further, in water inlet and water outlet set temperature sensor and flow controller, according to Muffle furnace inside and outside
Temperature difference, water inlet and outlet temperature difference are automatically adjusted into water.
Preferably, one and the water cooling tube of the above are used on same square steel.
Preferably, the air inlet pipe is metal tube or ceramic tube.
Preferably, the insulating layer is high-alumina brick.
Preferably, the heating element is resistance wire, Elema or Si-Mo rod.
The beneficial effects of the utility model are：
The utility model adds the air inlet pipe connected with burner hearth in bottom of furnace body, it is formed together with original smoke exhaust pipe
Air circulation circuit between burner hearth and the external world, can continuously obtain the material in oxygen supply supply burner hearth from the external world
Oxidizing roasting process, so as to promote oxidizing roasting effect more rapidly abundant.By the way of water cooling, make the temperature of integrated steel-structure
Decrease drastically, also can be controlled in less than 200 DEG C even if temperature highest point, most of control is below 100 DEG C, and phase
Temperature difference with height distance end is less than 20 DEG C.The Muffle furnace principle of the utility model is simple, and the thermal efficiency greatly improves, low cost
It is honest and clean, it is easy to operate, greatly improve energy utilization rate.
Brief description of the drawings
, below will be to embodiment or existing in order to illustrate more clearly of the utility model embodiment or technical solution of the prior art
There is attached drawing needed in technology description to be briefly described.
Fig. 1 is the structure diagram of the utility model Muffle furnace.
Fig. 2 is the sectional view of the utility model Muffle furnace steel structure frame square steel tube.
