Embodiment Construction
[0014] A liner for a maintenance-free oil heating roller, comprising a liner main body 5, an oil inlet pipe 2 and an oil outlet pipe 12 are arranged at both ends of the liner main body 5, and the outer surface of the liner main body 5 and the roller shell of the heating roller The annular cavity is the heating chamber through which the heat transfer oil flows. The outer surface of the inner tank main body 5 is provided with a heat balance mechanism, and the two ends of the inner tank main body are provided with end plates 4. The outer edge of the end plate 4 and the inner surface of the roller shell A dynamic sealing structure is formed between them, and two chambers are respectively provided near the two end plates in the liner, one chamber is the oil inlet chamber 6, and the other chamber is the oil outlet chamber 9, both the inlet and outlet chambers are set through the The oil hole on the inner tank wall communicates with the heating chamber, and several temperature compens...

The invention discloses a maintenance-free liner of an oil heating roller. A heat balance mechanism is arranged on the outer surface of a main liner body, an oil inlet chamber and an oil outlet chamber are formed in the positions, close to two end plates, of the liner and are communicated with a heating cavity through oil holes in the wall of the liner, a plurality of temperature compensation oil pipes are arranged in the middle section between the oil inlet chamber and the oil outlet chamber, two ends of the main liner body are connected with an oil inlet pipe and an oil outlet pipe, thermal insulation linings are arranged in the oil inlet pipe and the oil outlet pipe, and air-cooling air cavities are formed between the thermal insulation linings and the inner walls of the oil inlet t pipe and the oil outlet pipe. Air is blown to the air cavities through air blowing pipes, hot air is taken away, and air cooling is realized. The heat balance mechanism arranged on the outer surface of the liner and the temperature compensation oil pipes are used for heating a roller casing uniformly, the roller body can be rapidly heated, and uniform temperature of the roller surface is kept; by means of thermal insulation measures of the inner and outer walls of the oil inlet pipe and the oil outlet pipe, a shaft head of the heating roller can be effectively insulated from heat and cooled, damage of a sealing element is reduced, and the service life of each of bearings at two ends of the shaft head of the heating roller is guaranteed.
Description
technical field [0001] The invention relates to an oil heating roller of textile machinery equipment, in particular to an inner container of a maintenance-free oil heating roller. Background technique [0002] The ironing rolls on the market today are basically electric heating rolls, and the oil heating rolls all use indirect heat transfer, the energy utilization rate is low, the temperature of the roll surface cannot meet the use requirements, and the oil outlet pressure of the boiler room and The oil outlet temperature has very high requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose an efficient and safe maintenance-free inner container for oil heating rollers in view of the deficiencies in the prior art. [0004] The technical problem to be solved by the present invention is achieved through the following technical proposals. A liner for a maintenance-free oil heating roller includes a main body o...
