Description

The hot bending baking box

Technical field

The utility model relates to a kind of heating unit, the electric heater unit of particularly a kind of processed glass and ceramic.

Background technology

At present, known specific glass hot bending heating unit all adopts coal as heat energy, and its maximum shortcoming is to be heated inhomogeneously, is easy to cause glassy product distortion, and yield rate is extremely low, and quality product is very unstable.The patent No. is that the Chinese patent " electric-heated viewscreen bending furnace " of CN03263721 discloses a kind of electric-heated viewscreen bending furnace, it is at the heat insulation body of heater of electric-heated viewscreen bending furnace upper end flat raft round calrod to be installed, the channel pin is fixed two movable channels, pulley fits in the movable channel of matrix mutually, the furnace bottom furnace bottom that is connected with fire door lies on the pulley, advance by pulley and to close the door or pull out and open the door, it is characterized in that heat insulation body of heater upper end flat raft installs round calrod.Its weak point is that side is opened the door and made heat-insulating property good inadequately, and power consumption is bigger.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of good heat insulating is provided, and is energy-conservation, and the measured hot bending baking box of product processed matter.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of hot bending baking box, comprise casing and loam cake, it is characterized in that: the guide rail that casing is moved forward and backward is arranged under the described casing, can make casing make the elevator actuating cylinder of up-and-down movement on the casing in addition, described loam cake is fixed on the support, quartz heating-pipe is arranged in the loam cake, on the sidewall of loam cake ventilation opening is arranged, thermal insulation layer is arranged around described casing and the loam cake.

For optimizing technique scheme, the measure that the utility model is taked also comprises:

Described thermal insulation layer is an aluminosilicate fiberboard, is fixed on the casing with ceramic permanent seat.

Have on the described casing and make the casing pneumatic ACTUATOR that move front and back on guide rail.

Described ceramic permanent seat comprises ceramics seat and stainless steel bolt.

Described quartz heating-pipe is connected on the loam cake sidewall by vitrified pipe.

On the described support shock spring is arranged.

Because the utility model has been taked above-mentioned technical measures, it compared with prior art has following advantage:

1, heat in the top: the condition that we know most chemical reaction needs is a high temperature, and material at high temperature can produce new material.If adopt bottom or sidepiece to heat, it is dirt settling such as mould that annexation such as required product processed and mould at high temperature are heated maximum.At this moment, annexation such as mould may produce unknown novel substance.Unknown novel substance may influence the quality of product.This situation just can not appear and adopt the top to heat, because product such as processed glass or pottery is the nonconductor or the semi-conductor of heat, product has protected dirt settlings such as mould can not accept very high temperature in dirt settlings such as moulds, materials such as aluminosilicate fiberboard can not produce unknown novel substance yet, product can reach design requirements, and has also protected the work-ing life of dirt settlings such as mould;

2, good heat insulating: whole heating space seals with aluminosilicate fiberboard, also is connected with the extremely low pottery of heat conduction with the junction of outside.Baking box is made has the thick aluminosilicate fiberboard of 70～80mm with wallboard, and the seam crossing of plate is interlaced, and casing also is to dock with aluminosilicate fiberboard with the loam cake place of closing up.If oven temperature rises to 600 ℃, cutting off the electricity supply to be incubated 2～3 days.Aluminosilicate fiberboard is in light weight, and is high temperature resistant, low heat conductivity, low heat capacity, good thermostability and heat-shock resistance;

3, be heated evenly by baking product: the nichrome wire of heating usefulness penetrates in the silica tube, and silica tube also comes the end face in the loam cake uniformly.Thermal source and the distance that 150～200mm is arranged by roasting product, thermal source does not contact by roasting product.Utilize heat radiation principle that product is heated, the whole baking box temperature difference has only 2～5 ℃;

4, energy-conservation: owing to whole heating space seals with aluminosilicate fiberboard, material low heat conductivity, low heat capacity, the baking box thermosteresis is extremely low, compares with tunnel furnace, can save heat 40～60%; Compare with existing baking box, can save heat 20～40%;

5, easy to operate: a people can operate many baking boxs.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

With reference to accompanying drawing, the utility model mainly comprises casing 8 and loam cake 1, and whole baking box is made thermal insulation layer 10 materials with aluminosilicate fiberboard, makes skeleton with stainless steel.Aluminosilicate fiberboard is fixed on casing 8 and the loam cake 1 with ceramic permanent seat 9.Loam cake 1 part utilizes the thermal radiation heat of electrothermal quartz tube 11 that product is heated as the heating zone.Following casing 8 parts size adapts with loam cake 1 part.Place required product processed in the casing 8, can change the internal space size of casing 8 according to the size of product.For example, when the height of mould and product is not high, can fill and lead up space, casing 8 lower section with aluminosilicate fiberboard, like this, casing 8 internal spaces reduce, and have saved heat energy.Casing has the guide rail 6 that casing 8 is moved forward and backward for 8 times, has on the casing 8 to make the casing 8 pneumatic ACTUATOR that move front and back on guide rail 4 and can make casing 8 make the Pneumatic elevation ACTUATOR 7 of up-and-down movement.Described loam cake 1 is fixed on the support 5, on 4 root posts of support 5 shock spring 19 is arranged, and can reduce vibrations when casing 8 picking-ups are coincide with loam cake 1.Be evenly equipped with quartz heating-pipe 11 in the loam cake 1.Quartz heating-pipe 11 is penetrated in the silica tube 13 by nichrome wire 16 and makes, and quartz heating-pipe 11 is connected on loam cake 1 sidewall by vitrified pipe 14, and fastening with ceramic screw 15.Nichrome wire 16 connects lead 2.Described ceramic permanent seat 9 comprises ceramics seat 18 and stainless steel bolt 17.Ventilation opening 3 and temperature sensor are arranged on the sidewall of loam cake 1.Operating process is: roasting product is put into casing 8, controller instructs pneumatic ACTUATOR 4 pulling casings 8 to loam cake 1, instructing a pair of elevator actuating cylinder 7 that casing 8 is held up with loam cake 1 again coincide, fix safety cock 12, energising is heated to temperature required, by temperature sensor and electric controller control design temperature.
