Description

A kind of pulse type pneumatic drier
Technical field
The utility model relates to pulse type pneumatic drier.
Background technology
The principle of pulse type pneumatic drier is that gas and particle follow the different characteristics of motion, caliber is repeatedly alternately made to reduce and expand, movement of particles is in the alternation procedure accelerated and slow down. be in non-movement at the uniform velocity state all the time, make air-flow and intergranular relative velocity and heat and mass area all larger, thus enhance heat and mass speed.In addition, the result that air velocity declines in expanding reach, adds the drying time of material.Chinese Patent Application No. 201110223901 discloses a kind of pulse type pneumatic drier, drying tube is alternately made up of big-diameter pipeline and small-caliber pipeline, the diameter of big-diameter pipeline and small-caliber pipeline is than 1.2:1 ~ 3.5:1, and big-diameter pipeline and small-caliber pipeline are same central axis.Traditional pulse type pneumatic drier cannot realize stock grading, and the particle diameter of dried material is often not of uniform size, affects end product quality.
Utility model content
The purpose of this utility model be to propose a kind of can improve air-flow mobile performance and the pulse type pneumatic drier that the particle diameter of dried material can be made to reach prescribed limit require.
For achieving the above object, the utility model takes following technical scheme: the utility model comprises air blast, heat exchanger, feeding device, drying tube, cyclone dust collectors and air-introduced machine, air blast is connected with heat exchanger, drying tube is alternately made up of the pulse tube of Large Diameter Pipeline and the accelerating tube of pipe with small pipe diameter, the accelerating tube being wherein in turning is arc-shaped accelerating tube, the end of drying tube is connected with the air inlet of cyclone dust collectors, the air outlet of cyclone dust collectors is connected with described air-introduced machine, it is characterized in that: also comprise Venturi tube and impact air-flow pipe, under Venturi tube, upper end respectively with the air outlet of heat exchanger, the initiating terminal of drying tube connects, in Venturi tube, top is respectively equipped with charging aperture and air inlet, the two ends of described impact air-flow pipe respectively with the air outlet of heat exchanger, the air inlet of Venturi tube connects, the auger conveyor of described feeding device stretches in Venturi tube by the charging aperture of Venturi tube, be provided with hot-air distributor in impact air-flow pipe and adjust wind butterfly valve, the end being in the wherein joint pulse tube in the middle part of drying tube is provided with classification ring.
Described cyclone dust collectors comprise one cyclonic deduster and second cyclone dust extractor, the air outlet of one cyclonic deduster is connected with the air inlet of second cyclone dust extractor, the end of described drying tube is connected with the air inlet of one cyclonic deduster, and the air outlet of second cyclone dust extractor is connected with described air-introduced machine.
The utility model has following good effect: the utility model arranges Venturi tube and impact air-flow pipe, and Venturi tube can improve the mobile performance of air-flow, and material can better be driven to rise, and reduces bottom and leaks material.By the air-flow that impact air-flow pipe is radial to the top input of Venturi tube, the direction of motion being in Venturi tube top material is made upwards to change into rotation upwards by straight line, the time of staying of material in Venturi tube of greater particle size increases, and collision is pulverized mutually.Due to the change of material movement speed, strengthen heat transfer coefficient, this pulse type pneumatic drier has good drying effect.The setting of the utility model classification ring, passes therethrough the material meeting certain particle diameter, and the material of greater particle size then strengthens mutual pulverizing and drying in gas flow tube, and make the particle diameter of the dried material of output within the limits prescribed, the quality of product is guaranteed.

Detailed description of the invention
Embodiment 1
See Fig. 1, a kind of pulse type pneumatic drier of the present embodiment comprises air blast 1, heat exchanger 2, feeding device 7, drying tube 8, cyclone dust collectors, air-introduced machine 11 and Venturi tube 6 and impact air-flow pipe 4.
Described air blast 1 is connected with heat exchanger 2.The lower end of described Venturi tube 6 is connected with the air outlet of heat exchanger 2, the upper end of Venturi tube 6 is connected with the initiating terminal of drying tube 8, in Venturi tube 6, top is respectively equipped with charging aperture 6-1 and air inlet 6-2, one end of described impact air-flow pipe 4 is connected with the air outlet of heat exchanger 2, the other end of impact air-flow pipe 4 is connected with the air inlet 6-2 of Venturi tube 6, is provided with hot-air distributor 3 and adjusts wind butterfly valve 5 in impact air-flow pipe 4.The auger conveyor 7-1 of described feeding device 7 is stretched in Venturi tube 6 by the charging aperture 6-1 of Venturi tube 6.
Drying tube 8 is alternately made up of the pulse tube 8-1 of Large Diameter Pipeline and the accelerating tube 8-2 of pipe with small pipe diameter, and the accelerating tube being wherein in turning is arc-shaped accelerating tube 8-3.The end being in the wherein joint pulse tube in the middle part of drying tube is provided with classification ring 9, and the present embodiment takes the pulse tube end be connected with arc-shaped accelerating tube 8-3 initiating terminal to be provided with classification ring 9.
Cyclone dust collectors can be only have one cyclonic deduster 9, and the cyclone dust collectors of the present embodiment comprise one cyclonic deduster 9 and second cyclone dust extractor 10.The end of described drying tube 8 is connected with the air inlet of one cyclonic deduster 9, and the air outlet of second cyclone dust extractor 10 is connected with described air-introduced machine 11.The end of drying tube 8 is connected with the air inlet of one cyclonic deduster 9, and the air outlet of one cyclonic deduster 9 is connected with the air inlet of second cyclone dust extractor 10, and the air outlet of second cyclone dust extractor 10 is connected with described air-introduced machine 11.
When this pulse type pneumatic drier runs, air blast 1 and air-introduced machine 11 are opened, and start heat exchanger 2.When the leaving air temp of heat exchanger 2 meets the demands, open feeder 7 and feed intake.The material entering Venturi tube 6 axially rises in high-speed and high-temperature, due to by the top input high temperature low wet gas current of impact air-flow pipe 4 to Venturi tube 6, impact the air-flow at the above position of air inlet 6-2 in Venturi tube 6, make the air-flow on Venturi tube 6 top upwards change into rotation upwards by straight line, form swirling eddy and souring is played to inside pipe wall.
Because the motion of material rotates upwards, the material of fine particle size enters drying tube with air-flow, and the time of staying of material in Venturi tube 6 of greater particle size increases, and collision is pulverized mutually.The change of material movement speed, strengthens heat transfer coefficient, and this pulse type pneumatic drier has good drying effect.
At the material of dry Bottomhole pressure, when meeting Particle size requirements, pass through from classification ring 9, the material not meeting Particle size requirements then strengthens mutual pulverizing and dry in drying tube, meets after Particle size requirements again by classification ring 9.Dry complete material is via one cyclonic deduster 9 and second cyclone dust extractor 10 discharging.There is provided the pressure head of the air quantity needed for system by air-introduced machine 11, and humid air drying terminated is discharged.
