Description

A granular material drying device

technical field

The utility model relates to a drying device, in particular to a particle material drying device.

Background technique

When drying charcoal with water in the traditional process, the drying effect is not good, and the moisture content requirements of the customer contract cannot be met. The drying efficiency is low, and the re-drying increases the production cost, resulting in the failure to ship the product in time, resulting in a delay in the delivery date. In addition, in the traditional process, two drying furnaces share one chimney, and the height and diameter of the chimney are not clearly regulated.

The patent document (CN103727756A) with the application number of 201310700093.4 discloses a rotary dryer specially used for drying activated carbon bricks, including a rotary drying rack, a ceramic heating dryer, a temperature controller, a timing switch, activated carbon bricks, slow High-speed motors, motor rotating gongs and other components have the advantages of environmental protection, energy saving, safety and stability, and solve the technical problems of drying and dehumidification technology required for the miniaturized and personalized production of activated carbon bricks, but they are not suitable for drying large quantities of activated carbon particles. Dry operation; Another patent document "Drying method and drying device for charcoal production" (CN10176193B) discloses a drying method and drying device for charcoal production, including heaters, dryers and drive motors , The dryer sleeve is equipped with a propulsion device that propels the material to move forward evenly. This invention can improve heat utilization efficiency and reduce heat loss. Both of the above-mentioned documents have the problems of complicated equipment structure and high manufacturing cost.

Contents of the invention

Aiming at the problems and deficiencies in the prior art, the utility model provides a granular material drying device with simple structure, low manufacturing cost, high drying efficiency and the ability to complete large batches of operations.

The utility model is realized in the following ways:

A granular material drying device, including a belt conveyor, a combustion chamber, a vibrating screen, a drying furnace motor linkage device, a drying furnace supporting wheel, and a dust collection chamber. A drying furnace is arranged between the combustion chamber and the dust collection chamber. The drying furnace is supported by the supporting wheels of the drying furnace and driven to rotate by the motor linkage device of the drying furnace. aft chimney;

Further, the drying furnace is connected to the combustion chamber obliquely downward from the dust collecting chamber;

Further, the inclination angle of the drying furnace is: 4°-5°;

Further, the diameters of the upper and lower ends of the chimney are 33cm and 63cm respectively, and the height is 25m;

Further, the hopper is funnel-shaped;

Further, a spiral baffle is arranged inside the drying furnace.

The beneficial effects of the utility model:

1) Increase drying output and improve drying efficiency.

Before transformation: 4.2 tons of drying materials per shift, the moisture requirement is less than 5%, and the qualified rate after testing is: 3.36/4.2 = 80%;

After transformation: each shift dries 4.9 tons of materials, the moisture requirement is less than 5%, and the qualified rate after testing is: 4.41/4.9=90%; each shift dries 0.7 tons more materials, and the efficiency increases by about 17%.

2) The set chimney increases the suction force, increases the heat transfer efficiency, and improves the drying efficiency.

3) The setting of a reasonable height of the chimney reduces the amount of dust emission and makes the dust deposit in the dust collection chamber, which has an obvious environmental protection effect.

Among them: 1 belt conveyor, 2 hopper, 3 drying furnace, 4 combustion chamber, 5 vibrating screen, 6 drying furnace motor linkage device, 7 drying furnace supporting wheel, 8 dust collection room, 9 chimney.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings, so that the technical solutions and effects of the utility model can be easily understood.

The utility model provides a granular material drying device, which includes a belt conveyor 1, a combustion chamber 4, a vibrating screen 5, a drying furnace motor linkage device 6, a drying furnace supporting wheel 7 and a dust collection chamber 8, a combustion chamber 4 and a There is a drying furnace 3 between the dust collection chambers 8, and a spiral baffle is arranged inside the drying furnace 3. The drying furnace 3 is supported by the drying furnace supporting wheel 7, and is driven by the drying furnace motor linkage device 6 to collect dust. The top of the chamber 8 is provided with a funnel-shaped hopper 2, the vibrating screen 5 is located below the outlet of the drying furnace 3, and the tail of the dust collection chamber 8 is also provided with an upper end and a lower end with diameters of 33cm and 63cm respectively, and a height of It is a chimney 9 of 25m, and the drying furnace 3 is connected to the combustion chamber 4 with a downward slope of 4-5 degrees from the dust collection chamber 8 .

When the utility model is used, the combustion chamber 4 is first ignited so that the temperature of the combustion chamber 4 reaches 500°C; then the controller of the drying furnace 3 is turned on, the drying furnace motor linkage device 6 starts to run, and the drying furnace motor speed reaches 1200 rpm/s , the drying furnace motor linkage device 6 drives the drying furnace 3 to rotate; the granular material to be dried is added to the funnel-shaped hopper 2 through the belt conveyor 1; the granular material enters the drying furnace 3 through the feeding pipe at a uniform speed, and the material is dried In the drying furnace 3, the spiral curve is advanced, and the heat is reversely transferred from low to high to dry the material; the dried material is blocked by the spiral baffle in the furnace, and enters the vibrating screen 5 through the furnace tail outlet for screening and packaging , to complete the drying operation of the entire material.

It should be noted that due to the reasonable setting of the inner diameter and height of the chimney, the suction force is effectively increased, the exchange of hot and cold air is accelerated, and the drying efficiency is significantly improved; in addition, the process of the granular materials to be dried entering the drying furnace 3 During the process, the dust produced by thermal decomposition of the material is deposited in the dust collection chamber 8, and the treated flue gas is discharged through the chimney 9 to achieve the purpose of environmental protection.

The basic principles, main features and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments.
