4, carbon black particle requires to be carbon black particle elder generation low temperature to drying, and from inside to outside dry, in order to avoid quick-fried particle should acutely not beaten simultaneously, conventional dryer is difficult to overcome the high shortcoming of Dust Capacity.

Summary of the invention

The purpose of this utility model is that a kind of interior hot joining touch drying machine is provided at the deficiencies in the prior art, is characterized in adopting low temperature (650 ℃) mixed flue gas to enter the inner barrel in the cylinder, directly contacts with carbon black particle, and thermal loss is little, and efficient improves 30%.

The purpose of this utility model is realized by following technical measures

The outer cylinder body of interior hot joining touch roller drier is connected with inner barrel by connecting rib, and the inner barrel left end is connected with the hot gas inlet pipe by inner seal ring, hot gas inlet pipe peripheral hardware exhausting chuck, and the exhausting chuck is connected with flat-plate closure by exterior seal ring; The hot gas inlet pipe is connected with the hot air temperature adjuster, and the inner barrel right-hand member is connected with baffle plate by pipe nipple; Outer cylinder body peripheral hardware gear, support roller and heat-insulation layer; The variable-frequency motor driven wheel rotates inside and outside cylindrical shell; The outer cylinder body right-hand member is provided with some hoppers, and hopper is connected with the plane end socket, and end socket central authorities in plane set out the material frustum, and the plane end socket is connected with collecting box by sealing ring.

Inner barrel is set flight outward.

Establish flight in the outer cylinder body.

Establish bleeding point below the exhausting chuck.

The outer cylinder body left end is established charging aperture, and pellet enters in the outer cylinder body by inner cone.

Collecting box is divided into discharging opening.

Establish the tail gas import on the hot air temperature adjuster, left end is established the combustion product gases import, and right-hand member is established mixed gas outlet.

The gradient of cylinder is 1: 120.

The utlity model has following advantage:

1, the hot gas with combustion product gases is mixed into dry gas with recovery tail gas, temperature reaches about 650 ℃, directly enter inner core in the cylinder, walking to the cylinder afterbody disperses the back directly to contact counter-current drying, heat exchange efficiency height with carbon black, thermal loss is little, raise the efficiency more than 30%, traditional fire-box and refractory brick have been cancelled in the insulation of cylinder external application heat-insulation layer.

2, carbon black preheating and direct contact heat gas on inner core carries out the heat exchange dual-heated, and carbon black particle is beaten distance and reduced over halfly, improves the carbon black quality, has guaranteed dry mass.

3, two seals is used in the outside, and seal diameter little (charging aperture, discharging opening) remainder all adopts Welding Structure.

4, three kinds of function integration structural designs are carried out in charging aperture, suction opeing, hot air intake, the inner tube structure design, the cylinder slope is adjusted in discharging, utilizes frequency conversion to adjust rotating speed etc., has obtained good effect.
