Description

The mesh belt vacuum drier of the double-deck heat pipe-type heating plate

Technical field

The present invention relates to a kind of mesh dryer, especially a kind of mesh belt vacuum drier of the double-deck heat pipe-type heating plate.

Background technique

Mesh belt vacuum drier currently on the market is a kind of drying equipment of continuous operation, and mesh belt vacuum drier is current Main heating method be passed through in heating plate below upper layer transport band hot water, gas-vapor mix or other flow thermally conductive Jie Matter, on material transferring band, transmission belt carries material according to the speed of setting and successively passes through each heating zone, upper layer transport band material Heat-conducting medium (steam, hot water, conduction oil) in following heating plate transfers heat to the object in transmission belt by heating plate Material, material, which absorbs heat, evaporates its moisture, and water vapour is taken away by vacuum pump set, dry materials speed of the upper layer transport with upper surface Rate is slow, and the material on upper layer transport band will cause the uneven drying of material, shadow by the static conveying drying being stacked upon The drying effect of material is rung, dryness storehouse is discharged in the material after drying.

When heat-conducting medium (water, conduction oil) in the heating plate that the upper layer transport band of mesh belt vacuum drier is installed below is long Between when flowing thermally conductive in heating plate, will form scale grease on the plate body inside heating plate, the internal structure of heating plate is complicated, Scale grease on plate body inside heating plate does not allow easy to clean scale removal, has the heating plate of scale grease to will affect the biography of thermal energy Lead heat exchange.

Hot pipe technique is that one kind of the G.M.Grover invention of LosAlamos National Laboratory, the U.S. in 1963 is known as " heat The heat transfer element of pipe ", it takes full advantage of the quick thermal transport property of heat-conduction principle and refrigeration working fluid, and heat-conducting work medium passes through The heat of thermal objects is transmitted to outside heat source rapidly by " gas-liquid phase transition ", and the capacity of heat transmission is more than the thermally conductive energy of any known metal Power.

Summary of the invention

It is dry the purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of mesh belt vacuum of double-deck heat pipe-type heating plate Dry machine.

The technical solution adopted by the present invention are as follows: a kind of mesh belt vacuum drier of bilayer heat pipe-type heating plate includes drying Storehouse, wired belt conveyer, heating device, vacuum pump set, gas-guide tube, discharge gate, stirring unit.

Two, the upper surface of the top plate for being attached to lower heating plate below the upper layer transport band for carrying material to be dried is conveyed, is taken Heat-conducting medium with thermal energy by thermal energy conduction on the top plate of lower heating plate, thermal energy by the heat radiation of the top plate of lower heating plate and The heat-conducting mode of heat transfer carries out thermally conductive heating to the material to be dried carried on upper layer transport band.

Three, the stirring unit on the bottom plate of upper heating plate is to the thermally conductive heating of material in transmission belt, and material is in transmission belt Transmission effect of inertia under by the way that under the guidance of stirring unit, material is displaced on upper layer transport band, and material also changes object The original static state stacking of material, material carry out left and right and improve the thermal energy position progress heat different to material with upper and lower overturning movement It heats to radiation thermal conduction, improves the drying uniformity of material, improve dry materials efficiency and optimization dry materials effect.

Four, the material that upper layer transport band is carried is heated the bottom plate of the upper heating plate of device and the top plate of lower heating plate On thermal energy while thermally conductive heating, increase the conduction heating speed of thermal energy, improve the rate of drying of material.

The energy consumption index of the vacuum conductive drying of the mesh belt vacuum drier of the double-deck heat pipe-type heating plate is 2800- 4000kj/kg, and convective drying is 4000-7500kj/kg；The thermal energy availability of convective drying generally only has 20- 50%, and vacuum conductive drying theoretically can be close to 95%, the mesh belt vacuum drier of the actually double-deck heat pipe-type heating plate Thermal energy availability can achieve 60-80%.Vacuum conductive drying is than convective drying energy conservation 30-50% under normal circumstances, This is because the vacuum conductive drying of the mesh belt vacuum drier of the double-deck heat pipe-type heating plate does not need Hot-blast Heating material, so The lost thermal losses of exhaust is small.

Material carries out conduction vacuum drying under the vacuum state in dryness storehouse, and material is dried under vacuum conditions, is had No pressure difference-powered of standby convective drying, is subnormal ambient around the granule materials in dryness storehouse, after the moisture in material is heated Easily ejected from the volatilization of the internal gasifier of material.The boiling point of water is reduced when material constant rate of drying under vacuum state, The vaporization boiling temperature of moisture is reduced to 35 DEG C -60 DEG C from 100 DEG C in material, and material heating is minimum, and heat almost all is used to Hygroscopic water is evaporated, when such as approaching or being less than critical moisture content, the conduction of the mesh belt vacuum drier of the double-deck heat pipe-type heating plate is true The dry power savings advantages of sky are bigger, improve the availability of thermal energy in this way, reduce the total amount consumed of thermal energy.

The present invention has the advantages that compared with existing mesh belt vacuum drier: a kind of bilayer heat pipe-type heating plate The heat-conducting medium of mesh belt vacuum drier, high temperature gives upper layer transport band by the upper heating plate of heating device and lower heating plate simultaneously On material carry out conductive drying, thermal conversion efficiency is high and loss is small, improve thermally conductive heat transfer rate, the conduction heat exchange of thermal energy Availability is high.The moisture in material under vacuum state is easy to volatilize from the internal gasifier of material and eject after being heated, The boiling point of water is reduced when material constant rate of drying.Under the conveying effect of inertia of transmission belt, stirring unit is played to transmission material What the material taken was stirred does use；Material under the transmission effect of inertia of transmission belt under the guidance of stirring unit, material Material also changes original static of material and stacks when displacement has occurred, and the small-scale overturning that material control is moved, can be with It improves the thermal energy position progress heat radiation different to material thermally conductively to heat, improves the drying uniformity of material, improve object Expect drying efficiency and optimization dry materials effect.
