Description
Technical field
The utility model relates to paper industry, the special-purpose conduction oil drying cylinder of particularly a kind of paper machine device.
Background technology
Paper industry uses timber, straw, reed, rag etc. to be raw material, isolates cellulose through the HTHP boiling, processes paper pulp.Paper machine commonly used mainly is through Steam Heating with dryer cylinder, and this mode needs to produce steam with the coal heating boiler, and consumes energy is many, and contaminated environment, and certainly, dryer cylinder also has other modes of employing to reach.Chinese patent number: 99200513.2 disclose a kind of paper machine uses the conduction oil drying cylinder, and it belongs to paper machine and uses drying equipment.The conduction oil drying cylinder is made up of drying cylinder cylinder body, bearing block, travelling gear and conduction oil swivel joint.The drying cylinder cylinder body is for being blocked up the jacket type drying cylinder that constitutes by inner sleeve, outer sleeve, center oil pipe and forward and backward cylinder; Be provided with bearing block with the stifled large-diameter pipe that joins of forward and backward cylinder; Be provided with travelling gear in the rear bearing block outside; Be connected to the conduction oil swivel joint with the stifled large-diameter pipe end that joins of back cylinder, the oil-in of this joint communicates with the spray bar of the center of insertion oil pipe, and its oil-out communicates with the drying cylinder chuck.This structure, spray bar connects with the sealing ring formation rotatable sealing of the tube inner wall that is contained in the inner sleeve center and inserts the oil pipe tube chamber, causes the conduction oil seepage easily; And the drying cylinder cylinder body is in order to prevent seepage; Technology requires high, complex structure, and the jacket type drying cylinder conduction oil circulation that fills conduction oil needs compression pump to drive; And need conduction oil many, cost is higher.
The utility model content
Therefore, to above-mentioned problem, the utility model proposes a kind of simple in structure, conduction oil not easy to leak and the stable special-purpose conduction oil drying cylinder of the paper machine device of operating temperature.
For solving this technical problem; The utility model is taked following scheme: the special-purpose conduction oil drying cylinder of a kind of paper machine device; Comprise the drying cylinder cylinder body, be located at end cap and central shaft on the cylinder body both ends of the surface, this central shaft is located at the end cap central bore place rotationally, and said central shaft is a hollow shaft; Two free ends of this central shaft are respectively equipped with oil inlet pipe and flowline, are provided with the heat-exchange device that is communicated with oil inlet pipe and flowline in the said cylinder body.
Further; Said heat-exchange device comprises eight petroleum pipelines, two circular house stewards and is communicated with two circular house stewards' the many heat exchange manifolds that evenly are provided with; Said oil inlet pipe is connected with the petroleum pipeline at 90 ° at four intervals respectively; These four petroleum pipelines are connected with a circular house steward again, and other respectively four petroleum pipelines of said flowline are connected, and these four petroleum pipelines are connected with another circular house steward again.
Further, the both ends of the surface medial surface of said drying cylinder cylinder body is provided with thermal insulation layer.
Further, said central shaft is located at the end cap central bore place rotationally through bearing.
Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: be uniformly distributed in the cylinder body inboard through heat exchange manifolds, stable with the cylinder body heat exchange, the operating temperature of cylinder body is stable; And the utility model is simple in structure, and conduction oil is easy to leak not, thereby can extensively promote the use of.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is an A-A cutaway view among the utility model embodiment.
The specific embodiment
Combine the accompanying drawing and the specific embodiment that the utility model is further specified at present.
With reference to figure 1, Fig. 2; The special-purpose conduction oil drying cylinder of a kind of paper machine device of preferred the utility model; Comprise drying cylinder cylinder body 1, be located at end cap 2 and central shaft 3 on cylinder body 1 both ends of the surface, this central shaft 3 is located at end cap 2 central hole rotationally through bearing, and said central shaft 3 is a hollow shaft; Two free ends of this central shaft 3 are respectively equipped with oil inlet pipe 4 and flowline 5, are provided with the heat-exchange device that is communicated with oil inlet pipe 4 and flowline 5 in the said cylinder body 1.Said heat-exchange device comprises the circular house steward of eight petroleum pipelines 6,6 ', two 7,7 ' and be communicated with two circular house stewards' many heat exchange manifolds 8 that evenly are provided with; Said oil inlet pipe 4 is connected with the petroleum pipeline 6 at 90 ° at four intervals respectively; These four petroleum pipelines 6 are connected with a circular house steward 7 again; Said flowline 5 other four petroleum pipelines 6 ' respectively is connected, and these four petroleum pipelines 6 ' are connected with another circular house steward 7 ' again.The both ends of the surface medial surface of said drying cylinder cylinder body 1 is provided with thermal insulation layer 9.
During work, the conduction oil of heating gets into circular house steward 7 and evenly is arranged on the heat exchange manifolds 8 on the annulus with Duo Gen through the petroleum pipeline 6 of oil inlet pipe 4 through 90 ° at four intervals; Carry out heat exchange through heat exchange manifolds 8 and air and drying cylinder cylinder body 1; Make the drying cylinder center housing temperature reach operating temperature, flow out through petroleum pipeline 6 ', circular house steward 7 ' and flowline 5 then, and move in circles; Make the operating temperature of drying cylinder cylinder body stable, promote the drying of paper pulp.
The utility model is uniformly distributed in the cylinder body inboard through heat exchange manifolds, and stable with the cylinder body heat exchange, the operating temperature of cylinder body is stable; And the utility model is simple in structure, and conduction oil is easy to leak not, thereby can extensively promote the use of.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
