Abstract

The utility model relates to a hot blast rotary drum drying machine, comprising a rotary drum, a riding wheel, a power-driven device, a feed liquid groove, a scrapings knife, an upper cover and a base, and the like. The improvement point is that an inner barrel with a blocked end is arranged in the rotary drum and one end of the rotary drum is an open end for receiving hot blast. When in use, the drying machine is provided with a fire coal hot blast stove beside and blows the hot blast into the open end of the rotary drum through an air outlet of the hot blast stove, and the rest of hot blast is extracted out through an air extracting facility at the other end of the rotary drum. The drying machine is characterized by saving energy, coal, water and labor and the like, is widely applicable due to stepless regulation available for the temperature and rotary speed of the rotary drum according to the use requirement of different materials, and also conforms to the requirements of environmental protection, energy-saving and emission-reduction.

Description

The hot blast rotary drum dryer

Technical field

The utility model relates to a kind of device that material is separated by mode of heating from liquid, specifically a kind of hot blast rotary drum dryer.

Background technology

Existing rotary drum dryer (claiming " cylinder dried machine " again) includes rotary drum, support roller, Power Drive Unit, material fluid bath, scraper cutter, goes up cover and base etc.Mostly be to be equipped with the tubulation tube bank in rotary drum, the thermal source of drum dried is Boiler Steam or heat conduction wet goods.Therefore, it is essential that main equipments such as configuration steam boiler or heat-conducting oil furnace are to use existing rotary drum dryer.This not only makes user's equipment investment big, and the energy resource consumption in the use is big, and boiler, rotary drum all belong to pressure vessel, the manufacturing of equipment and instructions for use strictness, and have potential safety hazard.

The utility model content

The purpose of this utility model just provides a kind of hot blast rotary drum dryer, to reduce equipment investment, improves safety in utilization, and saves the energy.

The utility model is achieved in that a kind of hot blast rotary drum dryer, include rotary drum, support roller, Power Drive Unit, material fluid bath, scraper cutter, go up cover and base, institute's improvements are inner cores that a plug at end part is housed in rotary drum, and an end of rotary drum is for receiving the opening end of hot blast.Use this hot blast rotary drum dryer, need the other coal-fired hot-blast stove of establishing, the opening end by rotary drum is blown into hot blast in the cavity of rotary drum, simultaneously, at the other end of rotary drum the exhausting facility of chimney or air-introduced machine class can be set, in order to extract waste heat wind out.

Design philosophy of the present utility model, exactly by an inner core is set in rotary drum, to occupy the most of space in the rotary drum, and make between rotary drum and the inner core and to form a narrow tubular space, like this, the heat medium that enters in the rotary drum just can only pass through and the heating drum wall in this narrow tubular space.Because the slit between rotary drum and inner core is narrow, it is abundant effectively to add heat, and adding heat, integral body obviously reduces, so, utilize hot blast just can make rotary drum reach the heating-up temperature of material being carried out efficient drying, thereby also become possibility with regard to making rotary drum dryer utilize the hot blast of coal furnace to carry out dry heat.

Advantage of the present utility model, the one, drum dried equipment is changed into by the pressure operation does not have the operation of pressure, safe and reliable; The 2nd, only need dispose coal-fired hot-blast stove and do not purchase main equipments such as steam boiler or heat-conducting oil furnace, have reduced equipment investment; Three are to use coal-fired hot-blast stove to carry out dry heat, have energy-conservation, economize on coal, characteristics such as water-saving and recruitment are few, and the temperature of rotary drum and rotating speed also can carry out step-less adjustment according to the instructions for use of different material, thereby widely applicable, and meet the requirement of environmental protection and energy-saving and emission-reduction.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the rotary drum 13 of this novel hot blast rotary drum dryer is rolled by steel plate and is welded, and total length can be within 10 meters, and for integrally welded again after the multistage welding, or each section links together by flange.The rotary drum of lengthening, the hot blast path of having extended can be fully energy-conservation.After rotary drum is manufactured, fixing inner core 3 therebetween.It is the long cylinder bodily form that inner core 3 requires, and there is the tapered end shutoff at two ends.Rotary drum 13 two ends are the thinner slightly support tube part of diameter, and it divides into support roller 7, to support rotary drum 13 it can be rotated.The left side of rotary drum 13 needs with refractory material internal layer to be handled for receiving the opening end of hot blast, to reduce thermal loss.The right side port of rotary drum 13 hides end cap, is connected to air outlet on end cap.On air outlet, can connect air-introduced machine, utilize again with the waste heat wind that will extract out; Also can connect chimney, with the aerial directly discharging of waste heat wind direction.The Power Drive Unit 8 of this rotary drum dryer, material fluid bath 5, scraper cutter 6, on cover 11 and part such as base 2 all the counterpart with existing rotary drum dryer is identical, top at last cover 11 is provided with some chimneys 12, in order to the steam that produces in the discharges material dry run.Material fluid bath 5 is established on the bottom of rotary drum 13 or top, and scraper cutter 6 is laid in the appropriate location.Cloth on the rotary drum outer wall can be taked multiple modes such as impregnated, splashing type, cloth of coating-type or rolling-type, and the rotary drum unit can be single-drum, twin drum or drum arranged.The left end outside in this hot blast rotary drum dryer can be provided with a coal-fired hot-blast stove 1, is connected to chimney fan 9 on coal-fired hot-blast stove, and the edge, outer end of chimney fan 9 extend in the left side opening end of rotary drum 13, and keeps certain clearance.

For realizing the even heating of rotary drum better, the utility model is connected to spiral aviation baffle 4 on the barrel of inner core 3, thereby forms a spiral duct between rotary drum and inner core, to guide the hot blast in the rotary drum well, makes the being heated evenly property raising of rotary drum.

The utility model also is shaped on wind blade 10 in the port of the opening end of rotary drum 13.Wind blade is symmetrically distributed with the center, and the hot blast in the coal-fired hot-blast stove 1 directly enters rotary drum dryer by chimney fan 9, and under the effect of wind blade 10, hot blast is blown in the rotary drum 13 equably, thereby improves the heat drying process of material, improves dry mass.
