The heating mode of the utility model can be internal heating type, as well as external heating type. The utility model has the advantages of high thermal efficiency, high drying speed and relieved labor intensity of operators, has the function of drying, can simultaneously pulverize materials and form granular, can reduce procedures of the manufacturing process of some specific products, and can increase work efficiency.

Description

Revolver drier

The utility model belongs to drying equipment.

The common chamber dryer thermal efficiency is low, and to the not guarantee of quality of dry products, labour intensity is big, and function singleness does not have pulverizing, granulation function simultaneously, to the production process of some product, can not reduce operation link.As in the catalyst application facet, to the drying of catalyst feed, need dry about 20 hours, because rate of drying is slow, moisture is slow in the volatilization of material surface, has influenced the quality of catalyst.Dried material enters again to be pulverized in the miscellaneous equipment and granulation (becoming graininess).

The purpose of this utility model provides a kind of revolver drier, thermal efficiency height, and rate of drying is fast, and is easy to operate, also has to pulverize and form granular function.

Revolver drier of the present utility model, it is characterized in that comprising heat power supply device, incubator, double-deck rotating cylinder, rotating cylinder links to each other with transmission device, heat power supply device is arranged in the incubator, double-deck rotating cylinder is in incubator, the sidewall of inner core and urceolus is network structure, has charging hole on the inner core, communicates with dumping pit between inside and outside tube.

Double-deck rotating cylinder is divided into inner core and urceolus, and the granularity of cancellated order number of inner core and material adapts, and guarantees that the material that is dried does not enter urceolus, makes dried material enter into urceolus simultaneously.The cancellated order number of urceolus will guarantee that material is not released.Rotating cylinder is that network structure plays draught effect simultaneously.

The two ends of inner core and urceolus can be respectively a disk, and in order to gain in strength, the network structure of sidewall is by many supporter supports, and supporter is fixed on the disk.

Mode of heating of the present utility model can be an internal heating type, also can be external heating type.The internal heating type heat power supply device is arranged on the incubator bottom, can be electrical heating.External heating type, heat power supply device are the coiled structure, and this coiled structure links to each other with outer thermal source.Outer thermal source can be coal combustion heating, oil, gas firing heating, with hot-air or other heat-conducting medium as heat transfer medium.

Transmission device generally is made up of motor and gearbox.Double-deck rotating cylinder, incubator is coaxial links to each other with transmission device by bearing.

Incubator is to be provided with in order to prevent scattering and disappearing of heat, can adopt the multiple mode of prior art.

The utility model can also be placed the porcelain ball or the stainless steel ball of right quantity in inner core, play broken material and stirring action.Its consumption accounts for 1/10～1/3 of inner core volume.

Charging hole on the inner core can be arranged on the disk at rotating cylinder two ends, corresponding inner core position.Dumping pit is used for drawing off of dried feed, can open on the rotating cylinder disk at position between inner core and the urceolus, or open on the side of rotating cylinder.

Below in conjunction with the embodiment description of drawings:

Fig. 1, Fig. 2 are respectively structural representation of the present utility model;

Fig. 3 is the barrel configuration schematic diagram.

Among the figure: 1 motor, 2 gearboxes, 3 bearings, 4 double-deck rotating cylinder 5 incubators 6 heat power supply devices 7 air blasts 8 outer thermal source 9 inner cores 10 urceolus 11 disks 12 charging holes 13 transmission grooves 14 supporting axis 15 dumping pits 16 porcelain balls

The thermal source of Fig. 1 is an internal heating type.Heat power supply device 6 is an electrical heating elements, is arranged on incubator 5 bottoms.Incubator 5, the double-deck rotating cylinder 4 coaxial bearings 3 that pass through link to each other with gearbox.

Fig. 2 is an external heating type.Heat power supply device 6 is a coil pipe, is arranged on incubator 5 bottoms, and coil pipe forms circulation with outer thermal source 8.The same Fig. 1 of all the other structures.

Size according to rotating cylinder is equipped with the motor of suitable power and the gearbox that matches.

Incubator is made of double-deck iron sheet, is filled with insulation material between the two-layer iron sheet, and its shape can be square, cuboid, cylinder etc.One spring bearing 3 is respectively arranged in order to support rotating cylinder in the relative both sides of incubator.

Be divided into inner core 9 and urceolus 10 as the double-deck rotating cylinder 4 of Fig. 3, the two ends of inner core 9 and urceolus 10 are respectively disk 11, and the sidewall of inner core 9 and urceolus 10 is a stainless (steel) wire, and the order number of inner core 9 nets is in 100 orders, and the order number of urceolus 10 nets is less than 200 orders.The porcelain ball 16 of some is housed in the inner core, and its consumption is 1/10～1/3 of an inner core volume.Have two apertures with cover on the disk 11 of rotating cylinder one side, one of them is positioned at inner core 9 positions, is charging hole 12, and another is positioned at the position between inner core and urceolus, is dumping pit 15.Supporting axis 14 on the rotating cylinder links to each other with the bearing 3 of incubator and transmission device.

When this drier makes material obtain drying, also carried out broken and the granular material of formation to material.

Advantage of the present utility model:

Thermal efficiency height, rate of drying is fast, especially heat-sensitive substance is had effect preferably.It can also alleviate operator's labour intensity.Not only have functions/drying, also simultaneously material is pulverized and formed graininess, can reduce operation link, increase work efficiency the production process of some specific products such as catalyst.Below be Comparative Examples:

Get water content and be 75% calcium carbonate wet feed 500 grams, putting into the inner core volume is 2 liters, and the urceolus volume is in 4 liters the revolver drier, to carry out drying at 130 ℃.After 30 minutes, the water content of material drops to below 5%, measures its BET specific surface and reaches 150m ²/ g.

Get water content and be 75% calcium carbonate wet feed 500 grams, put into volume and be 10 liters chamber dryer, carry out drying at 130 ℃.After 15 hours, the water content of material drops to below 6.3%, measures its BET specific surface and reaches 9.7m ²/ g.
