Description
Technical field
The utility model relates to a kind of caprolactam heat fused device.
Background technology
The caprolactam melting furnace is to adopt coal-fired mode of heating at present, through coal-fired heat fused stove, makes the caprolactam raw material fusing far away in the stove.And caprolactam belongs to chemical products, can not see naked light, therefore has huge potential safety hazard, and breaking out of fire easily causes personal injury; Coal-fired in addition mode cost is high, and is seriously polluted.Need to reform the mode of heating of melting furnace in a hurry, need the novel melting furnace of a kind of safety, environmental protection.
The utility model content
The technical problem that the utility model will solve is the defective to prior art, and a kind of production efficiency height, environmental protection and energy saving, low, the safe caprolactam melting furnace of cost are provided.
The utility model solves the technical scheme that its technical problem adopted:
A kind of caprolactam melting furnace; Be provided with charging aperture and discharging opening; By burner hearth from inside to outside, the body of heater that forms by heat-conducting layer, heat-insulation layer, housing successively, the heat-conducting layer internal cavities forms burner hearth; Wherein: said heat-conducting layer is made up of heat-conducting layer inwall, heat-conducting layer outer wall, and conduction oil is filled in the space between heat-conducting layer inwall, the heat-conducting layer outer wall; Heat-conducting layer connects power supply, and cut-in temperature control system.There are space and heat-insulation layer and housing that the space is also arranged between heat-insulation layer that forms by exotic material and the heat-conducting layer outer wall.
The heat-conducting layer inwall is processed by corrosion resistant Heat Conduction Material, and the heat-conducting layer outer wall is processed by corrosion resistant not Heat Conduction Material.Temperature control system has the temperature set-up function, regulates temperature according to the materials amount; And can on design temperature, begin heating or stop heating.
The beneficial effect of the utility model is embodied in:
Reformed mode of heating, adopted the heating means of science environmental protection, and take heat-insulation layer, the measure of housing double-layer heat insulation, both improved the thermal efficiency (practicing thrift 50% than the coal-fired fusing of tradition caprolactam), reduced the heat loss that leaks simultaneously, operating ambient temperature has reduced;
Pernicious gases such as the CO that has stopped to produce when coal-fired, SO2 have protected that the workman's is healthy.
Temperature control system guarantees that melting furnace keeps relative constant set temperature, and raw material heating process is steady, has guaranteed not waste material simultaneously, and nondiscolouring has improved production efficiency.
Burn-off rate is fast, just can accomplish fusing in 10 minutes behind the filler.
Description of drawings
Embodiment to the utility model further specifies below in conjunction with accompanying drawing and the specific embodiment:
The cross-sectional view of Fig. 1 the utility model.
1, charging aperture, 2, the heat-conducting layer inwall, 3, the heat-conducting layer outer wall, 4, conduction oil, 5, heat-insulation layer, 6, housing, 7, power supply, 8, discharging opening.
The specific embodiment
Referring to Fig. 1, the utility model is a kind of furnace apparatus that melts caprolactam, and the every cover system of this melting unit is respectively equipped with charging aperture and discharging opening; Charging aperture is located at the upper furnace opening part, and discharging opening is located at the bottom, directly links to each other with burner hearth.
Body of heater is divided into three layers, and the innermost layer is heat-conducting layer (zone of heating), is made by two-layer high-quality stainless steel (corrosion-resistant)----heat-conducting layer inwall 2, heat-conducting layer outer wall 3, and conduction oil 4 is filled in the space between heat-conducting layer inwall 2, the heat-conducting layer outer wall 3; The middle second layer is a heat-insulation layer 5, is processed by the high-quality insulation material, and insulation prevents that heat scatters and disappears; Most external is a high-quality stainless steel outer casing 6 for the 3rd layer.Fusing body no pressure in fusion process produces, and is safe and reliable.
Heat-conducting layer connects power supply 7, and inserts external temperature control system.Temperature control system is scientific and reasonable, can be according to the temperature of prior setting, and Auto Power On, shutdown.The heat fused process just can be accomplished in 10 minutes, uninterruptedly fusing continuously in the production process.Guarantee that melting furnace keeps relative constant set temperature, raw material heating process is steady, has guaranteed not waste material simultaneously, and nondiscolouring has improved production efficiency.
The disposable fusible 100 kilograms of caprolactams of every cover system;
The heat-conducting layer inwall is processed by corrosion resistant Heat Conduction Material, and the heat-conducting layer outer wall is processed by corrosion resistant not Heat Conduction Material.Have between space and heat-insulation layer 5 and the outer casing 6 between heat-insulation layer 5 that forms by exotic material and the heat-conducting layer outer wall 3 space is also arranged.Heat-insulation layer, the measure of housing double-layer heat insulation had both improved the thermal efficiency (practicing thrift 50% than the coal-fired fusing of tradition caprolactam), reduced the heat loss that leaks simultaneously.
The open upper end place is provided with charging aperture 1, and the lower end is provided with discharging opening 8, and charging aperture 1 is provided with seal cover, when reinforced opens seal cover, after the caprolactam raw material is added from charging aperture 1, again with seal cover sealing charging aperture 1.After the heat fused, directly export the caprolactam of the fusing liquid in the burner hearth through discharging opening 8.Charging, discharging are carried out synchronously, thereby guaranteed the continuity of work, make the running of equipment high efficiency rate, reliable and stable.
The melting furnace frame bottom is equipped with arrangement for adjusting height, so device height can be regulated convenient feeding in raw material as required.
Routine, the fusing fusing point of caprolactam are 65 degree, and the optimum temperature in the present embodiment is the 100-120 degree, and the maximum temperature of equipment can reach 350 degree.The equipment overall power is smaller.
