Abstract

The utility model discloses an internal combustion drying cylinder, comprising a rotary cylinder body with infrared radiation coatings at the inner and outer walls, and a hollow end cover; a shorter non-rotating hollow pipe is inserted into the center of the end cover; a combustion pipe with a burner, a monitoring and control circuit with a monitoring and control head, a gas inlet pipe, a gas exhaust pipe and other devices are arranged inside the hollow pipe; a manhole and a transparent dual-layer glass manhole cover with a reflective film pasted in the middle are arranged on the hollow end cover; gas or liquid fuel is combusted in the cylinder body to heat the cylinder body and dry the materials. The existing steam drying cylinder has high consumption and is inefficient, which pollutes the environment and is a bulky high-temperature pressure vessel; the internal combustion drying cylinder eliminates the problems of high power cost and complex structure, and is a non-pressure temperature-adjustable light drying vessel with high efficiency, low consumption, less pollution to the environment, cheap energy and simple structure, which can enhance the productivity and improve the product quality.

Description

The internal combustion drying cylinder

1, technical field

The utility model internal combustion drying cylinder relates to a kind of drum dryer, and particularly a kind of direct use fuel is at the internal combustion drying cylinder of inner barrel burning heating cylindrical shell and material.

2, background technology

Use Boiler Steam to be thermal source for many years in industries such as papermaking, printing and dyeing, chemical industry, pharmacy, food, the heating rotary cylinder body is the outer thin material of drying more always.The weak point of this steam dryer is its high cost with low efficiency, contaminated environment, and the utmost point does not meet present saving energy, lowering energy consumption and reducing pollutants discharge spirit.Use the deficiency of the directly-heated infrared drying cylinder patent of electric energy and fuel to be present electricity price costliness, uneconomical economically, and complex structure.

3, summary of the invention

Because electricity price costliness, the complex structure and other problems of high cost with low efficiency, contaminated environment and the electric energy drying cylinder of above-mentioned steam dryer, purpose of the present invention are exactly to propose a kind of efficient low-consume, of low pollution environment, simple structure and the inexpensive internal combustion drying cylinder of the energy.

For reaching above-mentioned purpose, the present invention designed a kind of with gas or liquid fuel in the cylindrical shell internal combustion, and with the internal combustion drying cylinder of the external material of infrared radiation heating drying.

Its concrete scheme is: this internal combustion drying cylinder comprises that respectively there is the hollow end cap of a rotation at a rotary cylinder body, two ends, the left and right sides, respectively insert a short and non-rotary slightly hollow pipe in the centre bore of each end cap, the fuel channel of being with burner, the devices such as telemetry circuit, air inlet pipe and blast pipe that band observing and controlling head is housed are housed in this hollow pipe; On hollow end cap, have manhole and the double glazing manhole cover of transparent and middle subsides reflectance coating is housed; Barrel temperature can be :-100～600 ℃, drum speed can be: 0～3000 rev/min.

Above-mentioned cylindrical shell can be used material manufacturings such as steel, aluminium, copper material, cast iron and stainless steel; Cylinder inboard wall is coated with the dark coating that absorbs the high ceramic coating of infra-red radiation, cylinder body outer wall can be coated with the coating of infra-red china such as the hard wear-resisting oxide of light color and matter, carbide, nitride, boride or cermet material, wherein can dose the materials such as medical stone that water had activation.

The thermal source of combustion drying cylinder can adopt gaseous fuel within above-mentioned: it is gaseous fuels such as various natural combustible gases, artificial coal gas, liquefied petroleum gas; Or employing liquid fuel: it is kerosene, diesel oil, heavy oil, former wet goods liquid fuel.

Beneficial effect: the thermal source of the utility model internal combustion drying cylinder removes directly to heat the material of cylindrical shell and cylinder body outer wall with gas or liquid fuel, eliminate high consumption, poor efficiency, the contaminated environment of using steam to bring and the high temperature pressure vessel problem that exists, eliminated electric energy valency height and complex structure problem again; So it is inexpensive and simple in structure that the internal combustion drying cylinder is a light weight, efficient, low consumption, of low pollution environment, the energy, but temperature adjustment and be not with pressure again can be enhanced productivity and can be improved product quality.
