Description
Technical field
The present invention and a kind of blade dryer.
Background technology
I crosses sewage sludge harmlessness recovery energy technology also in the starting stage, and sludge drying still belongs to the starting stage, and special Treatment of Sludge factory is set up in many cities, and therefore sludge drying processes and contains huge technology and product market.The annual discharge capacity of China's municipal sludge is estimated to reach about 9,000,000 tons the most at last, moisture percentage in sewage sludge can be made to drop to less than 40% by mummification, reaches the requirement that mud economy is burned.Sludge heat drying facture is the most most popular current sludge disposal technology, and its method is varied, including direct contact type heat drying method and indirect contact heat drying method.Owing to direct contact type heat drying method will increase mud gas, this gas is more intractable, does not process and can produce secondary pollution, therefore indirect contact heat drying method is current domestic general sludge drying technique.
nullMost for paddle-dryer in indirect contact heat drying method，Its primary structure includes the housing in W type、Feeding mouth、Discharging opening、Steam vent and osculum，Two hollow shafts it are provided with in W shell body，Axle head is provided with control its driving motor rotated and gear train，Hollow shaft is provided with air inlet in driving motor side，It is connected with blade along hollow shaft setting direction，Wedge blade on two paddle shafts is in being crisscross arranged，Mud enters enclosure interior from charging aperture，Electric machine rotation drives main axis，Mud carries out agitation dry，Drying course there are gas and condensed water discharge from steam vent and osculum respectively，Mud after drying is from discharging opening discharges housing，Common blade dryer osculum is arranged at air inlet，Upper square tube steam，Lower square tube condensed water，Hollow shaft is inclined to set，The vapor film of heat is positioned at above hollow shaft，Cooling is back to after becoming condensed water discharge at osculum.
Blade dryer relies on heat transfer indirectly to heat, and drying efficiency is high, and required steam is few, environmental protection and energy saving.But traditional blade dryer is due to the particularity of its structure, in actual mechanical process, can there is problems in that 1, condensed water water velocity slow, at discharge outlet, easily produce incrustation scale, and while air inlet, easily the mud granule in the middle of surrounding environment is carried in hollow shaft, thus causes and block at discharge outlet；2, when drying sludge to moisture content about 60%, mud easily lumps, surface is hard, the inside is but sposh, although mud stirs in housing up and down, it be arranged in parallel between adjacent blades, actually being a process being promoted forward by mud of blade, mud is consistent with the blade direction of motion, therefore is difficult to be smashed；3, mud stickiness is relatively strong, and poor fluidity, in order to make mud move forward, when common blade dryer is installed, equipment needs overall to the certain inclination angle of one-tenth, discharging opening direction, but when device inclined is placed, can not well control the flowing velocity of mud, so be difficult to control drying sludge moisture；4, during drying sludge, mud easily seizes, and Spindle's heat emission bread is enclosed, and causes drying effect poor.
Summary of the invention
The deficiency existed for prior art, it is an object of the invention to provide a kind of blade dryer, can solve the problem that the problem of blocking at discharge outlet, and in mud drying course, the mud of caking can be smashed, without reclining device, it is also possible to promote mud to be moved along smoothly, and the phenomenon seized can be effectively improved in mud drying course.
A kind of blade dryer, including housing, it is provided with hollow shaft in described housing, described hollow shaft axle head is provided with its first motor rotated of control, and described hollow shaft top is provided with air inlet, and described hollow shaft bottom is provided with osculum, described osculum is outward extended with drainpipe, described drainpipe includes the siphon portion towards the convex setting in described air inlet direction, and top, described siphon portion is less than described hollow shaft bottom, and described drainpipe turns on connection at siphon portion water inlet pipe.
By using technique scheme, under normal state, condensed water flows out from osculum, top, siphon portion is less than described hollow shaft bottom, at hollow shaft, condensed water potential energy is higher than siphon portion, condensed water can pass through in siphon portion caliber, but owing under normal state, water velocity is the slowest, therefore condensed water can not arrive top, siphon portion, open water inlet pipe, instant water is made to be full of siphon portion, in siphon portion, pressure diminishes, thus form siphonage, condensed water at discharge outlet is aspirated, thus in the lump by particulate matter at discharge outlet, the magazine absorption such as incrustation scale, thus solve the problem of blocking at discharge outlet.
For achieving the above object, the technical scheme is that described hollow shaft has been wholely set blade along its setting direction, described propeller shank and the through setting of described hollow shaft, be provided with along described hollow shaft setting direction at described blade outer rim and smash bar, described in smash bar axle head and be provided with control it occurs counter-rotational second motor with described hollow shaft.
By using technique scheme, under the driving of the first motor, hollow shaft rotates with blade, block mud in housing is under the hollow shaft rotation with blade, rotate along equidirectional, it is provided with along hollow shaft setting direction at blade outer rim and smashes bar, owing to the second motor and the first direction of motor rotation are contrary, therefore smash bar and rotate backward with hollow shaft, blade, mud, during the most pushed, run into and smashes bar, and both form relative motion, bulk mud is smashed, so that mud is dried more uniform.
The present invention is further arranged to: described blade helically stretches setting along feeding end to discharge end direction.
By using technique scheme, hollow shaft rotates, and drives blade to rotate, setting is helically stretched due to blade, therefore the mud in housing smoothly can be pushed toward discharging opening one end in the middle of the process rotated, this structure is avoided device inclined certain angle to promote mud
, it is only necessary to control mud move forward speed by controlling charging rate and hollow shaft velocity of rotation, thus more effectively control mud drying time.
The present invention is further arranged to: described hollow shaft outer surface is provided with some lug bosses, described lug boss cross section triangular shape along feeding end to discharge end direction.
By using technique scheme, hollow shaft outer surface is provided with some lug bosses, and lug boss cross section triangular shape, and this structure is possible to prevent mud to seize, triangular tip structure can hollow shaft rotate process in the middle of by axle surface around mud interrupt, make drying effect more preferably.
The present invention is further arranged to: described housing upper surface is fixedly connected with cover, described cover is provided with charging aperture in the first motor side, described charging aperture inner surface is provided with fan assembly, described fan assembly includes blade and the 3rd motor, described blade is arranged towards described charging aperture opening side, described outer surface of motor is provided with fixing bar, and described charging aperture correspondence position offers the through hole adaptive with described fixing bar.
By using technique scheme, fixing bar is arranged in through hole, and the 3rd driven by motor fan blade rotates, to the sludge pretreatment entered from charging aperture, mud is stirred, makes mud granule less, so that mud is not easy caking during drying, dry the most uniform.
