Abstract
The utility model relates to a continuous momentary air-current type drying machine. The drying machine comprises an annular drying cavity formed by a nozzle box, a lower part pipeline and an upper part pipeline, which are connected together, wherein the nozzle box is a U-shaped horizontally-arranged pipe, a material inlet is arranged at the upper part of the nozzle box, a connecting flange is arranged at the two ends of the nozzle box respectively, more than two nozzles are uniformly arranged outside the middle part of the nozzle box, an air inlet box is connected with the nozzle box on one side of each nozzle, and a hot air inlet is arranged at the lower part of the air inlet box; both the upper part pipeline and the lower part pipeline are L-shaped, and a connecting flange is arranged at the two ends of pipelines respectively; and a material outlet is connected on one side of the upper pipeline. The whole drying machine is shortened to lower than 3 m, and has a compact structure; factory investment for the equipment is small; as the outer surface area of the drying pipe is rather small, heat loss is reduced, and drying efficiency is improved; as the equipment requires no drive, the failure rate of the equipment is low, and the maintenance cost is rather low; and the drying machine is suitable for drying the material with low melting point.
Description
Technical field
The utility model belongs to the drying equipment technical field of industry powder materials such as being applied to metallurgy, chemical industry, ore, medicine, light industry, is specifically related to a kind of continuous wink-dry equipment.
Background technology
At present, the pneumatic drier of existing similar techniques is generally the straight pipe type airflow drying machine, and wet powder material is sent into the import of drying machine by feeding device, and the hot blast by the heater heating contacts with material at the straight section drying tube, thereby plays the effect of drying.The length of this straight section drying tube is decided according to the water content requirement and the drying capacity of import and export material, is generally the 6-20m height and does not wait.Come out to carry out gas solid separation by equipment such as whirlwind or sack cleaners again from discharging opening, thereby finish the dry run of material by the material of drying.This pneumatic drier is owing to highly reach more than seven meters, and desired factory building height just requires very high, and investment cost is bigger, and also extremely inconvenient to safeguarding, managing.Because drying tube length is longer, thermal loss and windage are all bigger, so this drying machine thermal energy consumption is big, and drying efficiency is lower.
The utility model content
In order to cut down the consumption of energy, to reduce investment, improve drying efficiency, continuous moment pneumatic convey drier that the utility model provides a kind of new construction to have efficient circulation, high temperature, high pressure draught.
Concrete structure design of the present utility model is as follows:
Pneumatic convey drier comprised by nozzle box, lower pipeline and upper pipe and interconnected the ring-type drying chamber of forming a kind of continuous moment; Described nozzle box is horizontal U-shaped tubulose, and its top is provided with material inlet, and two ends are adpting flange, and the outside, middle part is laid with plural nozzle, and the nozzle box of described nozzle one side is connecting inlet box, and described inlet box bottom is provided with the hot blast import; Described lower pipeline and upper pipe are L shaped pipe, and two ends are adpting flange; Described upper pipe one side is connecting material outlet.
Described nozzle is a tubulose, and the angle between the nozzle box axis of nozzle-axis and U-shaped tubulose is the 0-90 degree.
Described inlet box one side is provided with case lid, and the hot blast import department of inlet box is connecting blast pipe.
Send in the ring-type drying chamber from several nozzles through high pressure positive blower through the hot blast that is heated to uniform temperature, the wet stock that in the ring-type drying chamber, adds or pasty material contacts and circulate flow at high speed in the ring-type drying chamber with top, the material of drying is drawn from material outlet by high-pressure suction fan, carry out the gas thing by equipment such as cyclone dust removal or bag-type dustings and separate, thereby finish whole dry run.
The useful technique effect of the utility model drying machine embodies in the following areas:
1, owing to adopt the swinging drying tube, so do not need very long drying tube, the complete machine height is reduced to below 3 meters, and this compact equipment is used this equipment factory building small investment.The external surface area of drying tube is less simultaneously, has reduced scattering and disappearing of heat, has improved dry efficient.
2, owing to adopt high temperature, high pressure dry wind, air velocity is fast, and the dry materials time is short, material and hot blast full contact, and heating surface area is big, and temperature of charge is difficult for improving, and therefore is fit to the drying of low melting point material.
3, because hot blast is recycling in the swinging drying tube, so thermal energy consumption is little, the drying efficiency height.
4, drying equipment itself need not to drive, so equipment failure rate is low, and maintenance cost is lower.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, a kind of continuous moment pneumatic convey drier comprise by nozzle box 1, lower pipeline 2 and upper pipe 3 and interconnect the ring-type drying chamber of forming.Nozzle box is horizontal U-shaped tubulose, its top is provided with material inlet 5, and two ends are adpting flange, and the outside, middle part is laid with three nozzles 7, nozzle is a tubulose, and the angle between the nozzle box axis of three nozzle-axis and U-shaped tubulose is respectively 5 degree, 45 degree, 80 degree.The nozzle box of nozzle 7 one sides is connecting inlet box, and the inlet box bottom is provided with the hot blast import, and hot blast import department is connecting blast pipe 6.Lower pipeline 2 and upper pipe 3 are L shaped pipe, and two ends are adpting flange; Upper pipe 3 one sides are connecting material outlet 4.
Its operation principle: send into drying machine by a high pressure positive blower from hot-air inlet pipe 6 through the high temperature wind that is heated to uniform temperature, three nozzles of arranging at an angle 7 on nozzle box 1 spray into the swinging drying tube, wet stock or pasty material are sent into material inlet 5 by charger, in the ring-type drying chamber and high temperature, high-pressure blast meets, at high temperature, under the high pressure wind action, material fully contacts with hot blast, and in the ring-type drying chamber, circulate at a high speed, the material of drying is drawn by high-pressure suction fan from the material outlet 4 of upper pipe 3, be provided with cyclone dust removal at high-pressure suction fan and 4 of material outlets, bag-type dusting or other dust collection device, finish the gas thing and separate, thus the drying of realization material.This equipment is scattered in the hot-air and with hot-air higher wet stock of water content or pasty material and fully contacts, thus in contact process moment remove moisture content and play desiccation.
Wherein the temperature and pressure of hot blast is decided according to material temperature, and the size of nozzle 7, shape and layout angle also need to adjust according to different materials, to reach optimal drying effect.
