Description

The hot blast deflector roll that a kind of paper machine dry-web is used

Technical field

The utility model relates to paper industry, the hot blast deflector roll that particularly a kind of paper machine dry-web is used.

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, its heat energy system is through acting on the inner cylinder face of roll body, is delivered to the roller outer surface again and just acts on and be with dried paper web, and efficient is not high, and its complex structure, technology require high.

The utility model content

Therefore, to above-mentioned problem, the utility model proposes a kind of simple in structure, can hot blast directly be uniformly distributed with and act on dryer felt to carry out the hot blast deflector roll that evenly dry paper machine dry-web is used with dried paper web.

For solving this technical problem; The utility model is taked following scheme: the hot blast deflector roll that a kind of paper machine dry-web is used; Comprise the deflector roll roll body, be located at end cap and central shaft on the roll body both ends of the surface, this deflector roll roll body is rotating to be located on the central shaft, and said end cap is provided with an annulus through hole; The outer face of said end cap is equipped with the air intake termination; The corresponding position of annulus through hole of said air intake termination and end cap has air outlet, offers air inlet on the lateral wall of said air intake termination, and said deflector roll roll body middle part endface position is provided with wind blocker; The two ends of said deflector roll roll body all is arranged with sealing ring, and said deflector roll roll body lateral wall is provided with outer vertically its external diameter downwind plate identical with the sealing ring external diameter that disperses.

Further, said sealing ring is provided with the ring groove concentric with central shaft, said end cap be provided with sealing ring on the suitable annulus boss of ring groove, form through ring groove and annulus boss and to closely cooperate.

Further, said sealing ring is provided with the annulus boss concentric with central shaft, said end cap be provided with sealing ring on the suitable ring groove of annulus boss, form through annulus boss and ring groove and to closely cooperate.

Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: form many air channel structures through wind blocker and downwind plate are set, hot blast is blowed to uniformly be with dried paper web, improve drying efficiency and quality with dried paper web; Easy for installation, can need not to change the paper machine with common dryer felt deflector roll exchange; Whole roll body is in light weight, rotates flexibly, makes dryer felt drive rotation easily, and is easy to use.

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the right view of left end cap 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, and Fig. 3, the hot blast deflector roll that a kind of paper machine dry-web of preferred the utility model is used comprises deflector roll roll body 1, is located at left end cap 2, right end cap 3 and central shaft 4 on deflector roll roll body 1 both ends of the surface; This deflector roll roll body 1 rotating being located on the central shaft 4, said left end cap 2 is provided with an annulus through hole 21, and said right end cap 3 is provided with an annulus through hole 31; The outer face of said left end cap 2 and right end cap 3 is respectively equipped with air intake termination 5; 6, said air intake termination 5 has air outlet 51,61 with the corresponding position of annulus through hole of air intake termination 6 and left end cap 2 and right end cap 3; Offer air inlet 52 respectively on the lateral wall of said air intake termination 5 and air intake termination 6; 62, said deflector roll roll body 1 middle part endface position is provided with wind blocker 7, and the two ends of said deflector roll roll body 1 all is arranged with sealing ring 8; 9, said deflector roll roll body 1 lateral wall is provided with outer vertically its external diameter downwind plate 10 identical with the sealing ring external diameter that disperses.Said sealing ring 8,9 is equipped with the annulus boss 81,91 concentric with central shaft, and said left end cap 2 is respectively equipped with and sealing ring 8 with right end cap 3; The ring groove 22,32 that annulus boss 81,91 on 9 is suitable; 22,32 formation closely cooperate with ring groove through annulus boss 81,91.(certainly, annulus boss and ring groove also can be provided with conversely.)

The utility model forms many air channel structures through wind blocker and downwind plate are set, and hot blast is blowed to uniformly be with dried paper web, improves drying efficiency and quality with dried paper web; Easy for installation, can need not to change the paper machine with common dryer felt deflector roll exchange; Whole roll body is in light weight, rotates flexibly, makes dryer felt drive rotation easily, and is easy to use.

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.
