Abstract

The utility model discloses a sleeve type device for drying coal slime through smoke, which comprises an outer sleeve body and an inner sleeve body which are connected through a first bearing. Both ends of the inner sleeve body are outside of the outer sleeve body, and at least one end of the inner sleeve body is connected to a rotating driving device. A feed port and a discharge port are disposed at both ends of the inner sleeve body, the feed port is connected to the inner sleeve body through a second bearing, and the discharge port is connected to the inner sleeve body through a third bearing. A smoke inlet is arranged at the end of the outer sleeve body close to the feed port, a smoke outlet is arranged at the end of the outer sleeve body close to the discharge port, and an inner wall of the inner sleeve body is provided with a thread groove. The outer sleeve body, the feed port, the discharge port and the rotating driving device are installed on a support. The sleeve type device enables smoke and coal slime to exchange heat in the mode of non-direct contact, the smoke and the coal slime both have respective passages, and the rotating inner sleeve body can enable the smoke and the coal slime to exchange heat evenly. The thread groove enables the coal slime to move horizontally, saves space and meanwhile increases heating area.

Description

A kind of device of telescopic flue gas drying coal slime

Technical field

The utility model relates to a kind of drying machine, exactly is a kind of device of telescopic flue gas drying coal slime.

Background technology

China's coal grade height does not wait, and excursion is wide, and according to the existing energy policy of China, steam coal should use low-grade colm.Particularly power industry should select to burn the low big coal of moisture content of grade.At present to the colm dehydration coal slime drying machines that adopt more.Existing coal slime drying machine on the market, for drying all has, the general flue gas of heat that adopts directly contacts with coal slime, still, easy like this coal slime is caused, and makes the quality decline of coal slime.Though correlative technology field the technical staff improve, coal slime is carried out indirect by independent passage, and the coal slime passage needs oblique arrangement, and coal slime is fallen by the gravity effect from the high point of passage, and equipment occupation space is bigger.

The utility model content

The purpose of this utility model provides a kind of device of telescopic flue gas drying coal slime, not only can make the coal slime uniform drying, can be flue gas and coal slime noncontact heat exchange simultaneously, guarantees the quality of coal slime.

The utility model is achieved through the following technical solutions for achieving the above object: comprise outer cylinder body and inner barrel, connect by clutch shaft bearing between outer cylinder body and the inner barrel; The two ends of inner barrel outside outer cylinder body and at least one end be connected with rotating driving device, the inner barrel two ends are provided with charging aperture and discharging opening, are connected by second bearing between charging aperture and the inner barrel, are connected by the 3rd bearing between discharging opening and the inner barrel; Advance mouth with the approaching end setting of charging aperture on the outer cylinder body, set out mouth with the approaching end of discharging opening on the outer cylinder body, the inner barrel inwall is set to thread groove; Outer cylinder body, charging aperture, discharging opening and rotating driving device are installed on the bracing frame.

In order further to realize the purpose of this utility model, can also be by the following technical solutions: described rotating driving device comprises motor, motor is connected with bracing frame, decelerator is installed on the motor, carrying roller is installed on the decelerator, carrying roller is installed on the bracing frame by the carrying roller bracing frame, and carrying roller contacts with the inner barrel outer tube wall.

Advantage of the present utility model is: telescoping structure makes flue gas and the non-direct contact heat-exchanging of coal slime, and flue gas and coal slime have passage separately, and the inner barrel of rotation can make flue gas and coal slime uniform heat exchange.Thread groove makes coal slime can finish level and advances, and has increased heating surface area when having saved the space.The utility model also has compactness simple for structure, advantage cheap for manufacturing cost and easy to use.

Fig. 1 is a structural representation of the present utility model; Fig. 2 is the plan structure schematic diagram of Fig. 1; Fig. 3 is the sectional structure schematic diagram along Figure 1A-A line.

Reference numeral: 1 charging aperture, 2 discharging openings 3 advance mouth 4 outlet flues 5 outer cylinder bodies 6 inner barrels 7 thread grooves 8 clutch shaft bearings 9 bracing frames 10 motors 11 gearboxes 12 carrying rollers 13 carrying roller bracing frames 14 second bearings 15 the 3rd bearing.

The specific embodiment

The device of a kind of telescopic flue gas drying coal slime described in the utility model, as Fig. 1, Fig. 2 and shown in Figure 3, comprise outer cylinder body 5 and inner barrel 6,, connect by clutch shaft bearing 8 between outer cylinder body 5 and the inner barrel 6 for reducing friction and increasing the support of 5 pairs of inner barrels 6 of outer cylinder body; The two ends of inner barrel 6 outside outer cylinder body 5 and at least one end be connected with rotating driving device, inner barrel 5 two ends are provided with charging aperture 1 and discharging opening 2, for reducing friction and increasing the support of charging aperture 1 and 2 pairs of inner barrels 6 of discharging opening, be connected by second bearing 14 between charging aperture 1 and the inner barrel 6, be connected by the 3rd bearing 15 between discharging opening 2 and the inner barrel 6; Advance mouth 3 with the approaching end setting of charging aperture 1 on the outer cylinder body 5, set out mouth 4 with the approaching end of discharging opening 2 on the outer cylinder body 5, inner barrel 6 inwalls are set to thread groove 7; Outer cylinder body 5, charging aperture 1, discharging opening 2 and rotating driving device are installed on the bracing frame 9.Under the effect of rotation centripetal force, form material curtain uniformly simultaneously.High-temperature flue gas enters in the outer cylinder body 5 from advancing mouth 3, discharges at outlet flue 4.Flue gas evenly heats heat transferred inner barrel 6 through 6 pairs of coal slimes of inner barrel, thereby realizes carrying out uniformly exchange heat; Simultaneously this structure makes between coal slime and the flue gas and does not contact, and has guaranteed the quality of coal slime.Thread groove 7 makes coal slime can finish level and advances, and has increased heating surface area when having saved the space.

Described rotating driving device comprises motor 10, and motor is connected with bracing frame, and decelerator 11 is installed on the motor 10, and carrying roller 12 is installed on the decelerator 11, and carrying roller 12 is installed on the bracing frame 9 by carrying roller bracing frame 13, and carrying roller 12 contacts with inner barrel 6 outer tube walls.Rotate balance more in order to ensure, a cover rotating driving device is all installed at outer cylinder body 5 two ends.As Fig. 2, shown in Figure 3, two cover rotating driving devices can be installed also at outer cylinder body 5 two ends respectively.

The technical solution of the utility model is not restricted in the scope of embodiment described in the utility model.The utility model not technology contents of detailed description is known technology.
