Abstract

The utility model relates to a crucible internal heating burden-material heating device which comprises a heat preserving barrel (1), a crucible (2), a heating element (3), an upper cover (4) and a crucible cover (5); the crucible (2) is placed on supporting seats (13) and (14) in the heat preserving barrel (1), a hollow circular cylinder inwardly dented is arranged in the middle at the bottom of the crucible (2), the heating element (3) is arranged in the hollow circular cylinder, the crucible cover (5) is arranged at the upper part of the crucible (2), and the upper cover (4) is arranged at the upper part of the heat preserving barrel (1) and is in close contact with the heat preserving barrel (1). Due to the adoption of the technical scheme of crucible internal heating, the heating element only performs heating to the crucible, therefore, the heat loss is small, the heat efficiency is high, and the temperature rising rate is high; and the heating element is arranged inside the crucible, therefore, the furnace inner space occupied by the heating element is reduced, the capability of the crucible is improved, the charging amount is increased, the coating materials prepared by each furnace reach 100 kg, the output is improved by two times, and the electric power consumption at the constant temperature is only 3 myriawatts.

Description

Heating heating furnace materials device in the crucible

Technical field

The utility model relates to heating heating furnace materials device in the crucible.

Background technology

Now, by MgF ₂Or SiO ₂The generalized section of the old-fashioned preparation facilities structure of the preparation Coating Materials of preparation Coating Materials, as shown in Figure 1, it is made of body of heater and heat-insulation layer 15, crucible 6, calandria 7 and loam cake 8; Described calandria 7 places between the internal layer of crucible 6 and heat-insulation layer 15, and loam cake 8 places the top of body of heater and heat-insulation layer 15.Described calandria 7 and and the internal layer of the skin of crucible 6 and heat-insulation layer 15 between bigger space to be arranged in order to avoid the company of causing is electric, calandria 7 and and the internal layer of the skin of crucible 6 and heat-insulation layer 15 between all space bigger more than the 20mm to be arranged.The problem of its existence is: also to the internal layer heating of heat-insulation layer 15, the heat utilization efficiency of heating furnace charge is low, causes thermal losses big, wastes energy in the time of 6 heating of 7 pairs of charging crucibles of calandria; Because it is big that calandria takes up room when using, the volume of heating furnace materials device also can be big, perhaps, just must so just reduce charging, also cause the volume-diminished of crucible 6 efficient of preparation material to reduce in order to keep certain volume.So every stove can only prepare Coating Materials 20kg-50kg, the constant temperature power consumption is about 3 myriawatts.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides heating heating furnace materials device in the crucible.Heating heating furnace materials device can use powder or granular material in the crucible of the present utility model, especially uses MgF ₂Or SiO ₂The preparation Coating Materials.The structural profile schematic diagram that this heating furnace materials device constitutes as shown in Figure 2, this device is made of heat-preservation cylinder 1, crucible 2, calandria 3 and loam cake 4 and crucible cover 5; Crucible 2 places the inside of heat-preservation cylinder 1, it in the middle of the bottom of described crucible 2 cylinder of an inside recessed hollow, the cylinder of this hollow is built-in with calandria 3, and crucible cover 5 places crucible 2 tops, and loam cake 4 places the top of heat-preservation cylinder 1 and closely contacts with heat-preservation cylinder 1.

During use, raw material is added 2 li in crucible, cover crucible cover 5, again loam cake 4 is placed the top of heat-preservation cylinder 1 and closely contact with heat-preservation cylinder 1; Energising is heated.Obtain taking out behind the target material and get final product.

Beneficial effect: heating heating furnace materials device in the crucible that the utility model provides, use MgF ₂Or SiO ₂The preparation Coating Materials.The technical scheme of heating in the utility model employing crucible, because calandria almost only heats crucible, thermal losses is little, and heat is used the rate height, and programming rate is fast; Because calandria is in the inside of crucible, only to the internal layer heating of crucible, heat has improved with rate calandria, and greatly reduces the shared space of calandria, and the crucible capacity has increased, and charge has also increased.Under the constant temperature power consumption has only condition about 3 myriawatts, kg surplus the Coating Materials of every stove preparation reaches 100, output improves twice.

The specific embodiment

Embodiment 1

As shown in Figure 2, this device is made of heat-preservation cylinder 1, crucible 2, calandria 3 and loam cake 4 and crucible cover 5; Described crucible 2 places on the inside bearing 13,14 of heat-preservation cylinder 1, it in the middle of the bottom of described crucible 2 cylinder of an inside recessed hollow, the cylinder of this hollow is built-in with calandria 3, described crucible cover 5 places on the crucible 2, and described loam cake 4 places the top of heat-preservation cylinder 1 and closely contacts with heat-preservation cylinder 1.

The physical dimension of described crucible 2 is: φ 400mm, and high 600mm, the physical dimension of loam cake 4 is: φ 400mm, calandria 3 is 3 addition hot bodys, physical dimension is: φ 90 * 600mm.

The technical scheme of heating in the utility model employing crucible, because calandria almost only heats crucible, thermal losses is little, and heat is used the rate height, and programming rate is fast; Because calandria is in the inside of crucible, greatly reduce the shared furnace inner space of calandria, the crucible capacity can increase, and charge increases, and under the constant temperature power consumption had only condition about 3 myriawatts, every stove prepared Coating Materials and reaches 100kg, and output improves twice.

Claims
