Description
Technical field
The utility model relates to a kind of manufacturing installation of carbon-fiber heat-insulation material.
Background technology
Along with the progress of science and technology, all there is great demand in fields such as military, national defence and scientific research to rare metal (as molybdenum tungsten etc.) and magneticsubstance.And the production of these materials all has direct or indirect relation with High Temperature Furnaces Heating Apparatus, vacuum oven.In addition, in the industrial technology field, workpiece or raw-material pyroprocessing are all finished in vacuum high temperature furnace or inert atmosphere furnace.Temperature is generally all more than 2000 ℃ in the stove of vacuum high temperature furnace, this has just proposed very harsh requirement to lagging material---and not only required high insulating effect to save the energy but also require high temperature resistant, durable in use pollution-freely, this also is the development trend of high-temperature heat insulation heat insulating material.And common lagging material all can't bear so high temperature, and carbon fiber thermal insulating material becomes the preferred material of high temperature insulating insulation owing to its superior insulative properties, low heat capacity.
There are low, yielding, the easy efflorescence of intensity, effect of heat insulation difference and dismounting, installation shortcoming such as waste time and energy in the general soft carbon felt (Nomex) that adopts of employed heat-insulation and heat-preservation material in the present domestic high-temperature vacuum furnace, the heat-insulation and heat-preservation material of this structure.And rigid carbon-fiber heat-insulation material will overcome the existing shortcoming of this heat-insulation and heat-preservation of soft carbon felt, will be widely used as high temperature furnace used heat-insulation and heat-preservation materials such as crystal furnace, ceramic post sintering stove, gaseous phase deposition stoves.
The hard felt of present domestic carbon fiber mainly adopts soft carbon felt dipping mold pressing or the layering of soft carbon felt dipping to paste the moulding process of (graphite paper and carbon fiber are pasted at interval).The shortcoming that soft carbon felt dipping former compression technology exists is that product strength is low, the easy delamination splitting of goods under the high temperature working conditions, and work-ing life is short etc., because intensity is relatively low, it is convenient inadequately to remove and install; The hard felt that adopts layering stickup shaping mode to make, though intensity increases, the thermal conductivity of goods increases, the heat-insulating property variation reduces effect of heat insulation.
Summary of the invention
The purpose of this utility model is for the manufacturing installation of a kind of rigid carbon-fiber heat-insulation material that provides is provided, and apparatus structure is simple, and is reasonable in design.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of manufacturing installation of rigid carbon-fiber heat-insulation material, this device is connected to form successively by batch mixing pond, moulding pond, vacuum tank, cyclic water tank, in the moulding pond, be provided with the vacuum filtration device, between vacuum tank and batch mixing pond, be provided with Non-blinding pump, between vacuum tank and cyclic water tank, be provided with water-ring pump.
Described tabular lagging material vacuum filtration system is made up of plate-like product mould, filter screen, sieve plate, valve tube, is preform at the plate-like product mould inside, is provided with filter screen, sieve plate successively, valve tube below the plate-like product mould.
Described tubular lagging material vacuum filtration system is made up of in the tubular space left template, right template, filter screen, sieve plate, tubular is placed with preform in the space, the preform bottom is provided with filter screen, sieve plate successively, and the valve tube two ends are provided with left pump orifice and right pump orifice.
The utility model has the advantages that rational in infrastructurely, easy to use, adopt this device can produce low density, lower thermal conductivity and high-intensity rigid heat insulating material; Technologies such as concentration that can be by changing binding agent, ground carbon fiber length, forming vacuum degree are adjusted the density of lagging material; Technology is simple, and stability is high, and is easy to operate.According to the present invention, can be made into density is 0.1～0.4g/cm
3The low density insulation products, can make the lagging material that thermal conductivity is lower than 0.4W/mK.
