Abstract

The utility model relates to textile machinery, in particular to an S-shaped sealed head stainless steel drying cylinder, which is characterized in that the middle portions of the cross sections of aleft sealed head (3) and a right sealed head (9) are in a flat-plate shape, the part ranging from the outer circumference of the middle flat plate to an outer circumference connected with a cylinder (5) is in a circular arc concave shape, the middle flat plates of the left sealed head (3) and the right sealed head (9) are respectively provided with center hole bases, a left shaft head (2) and a right shaft head (10) are respectively connected on the center hole bases, the circular concave of the left sealed head (3) is provided with a handle hole base (1) and a vacuum valve seat (4), and the circular arc concave of the right sealed head (9) is provided with a plug screw (7) and a balance block (8). The sealed head integrates the advantages of a butterfly sealed head and a flat-plate sealedhead, and overcomes the disadvantages of the butterfly sealed head and the flat-plate sealed head. The S-shaped sealed head stainless steel drying cylinder has the characteristics that the wall thickness of the sealed head is small, a connecting shaft head with a base is short, the support bearing condition is excellent, the process heat transfer is even, and the engineering application value ishigh.

Description

S type end socket stainless steel drying cylinder

Technical field:

The utility model relates to a kind of textile machine, particularly a kind of S type end socket stainless steel drying cylinder.

Background technology:

The stainless steel drying cylinder is to be widely used in weaving, print and dye drying plant in the production process, adopt water vapour as thermal source, drying cylinder rotates by bolster, placing the drying cylinder surface to do oven dry textiles such as yarn, cloth handles, steam temperature is generally at 150～175 ℃, pressure 0.4～0.8MPa, and the cylindrical shell specification has different series such as diameter of phi 570, Φ 800, length 700～2000, the cylindrical shell material is a stainless steel, and end socket generally adopts carbon steel.

What use was maximum at present is butterfly end socket stainless steel drying cylinder, as shown in Figure 3, in GB150 " GB150-1998 ", such end socket has been stipulated corresponding design and calculation method, be characterized in that the end socket wall thickness is little, comparatively economical, while is owing to end socket and cylindrical shell employing is fillet welding joint, thereby welding deformation is less, but because end socket adopts indent formula structure, the bolster that needs is longer, and bearing capacity is poor, causes service life of equipment short, heat transfer dead angle, angle joint place is bigger in addition, has caused the heat-transfer effect at this place poor;

Flat-plate closure stainless steel drying cylinder has and conducts heat evenly as shown in Figure 4, and bolster length is short, the characteristics that bearing capacity is strong, but it is often bigger to design its design thickness by GB150 " GB150-1998 ", causes material consumption very big, the manufacturing cost height, the corner joint of flat-plate closure and book wall cylindrical shell is difficult to accomplish complete penetraction and fusion in welding, the stressed complexity of this node Welding Structure, difficult design, and weld seam filling metal is more, not only be easy to generate weld defect, also can bring bigger welding deformation.

The utility model content

The purpose of this utility model is to provide a kind of overcome butterfly end socket and the existing shortcoming of flat-plate closure, a kind of S type end socket stainless steel drying cylinder that has butterfly end socket and flat-plate closure advantage simultaneously.

For achieving the above object, the technical scheme that the utility model adopted is: this S type end socket stainless steel drying cylinder comprises the hand hole seat, left side spindle nose, vacuum valve seat, cylindrical shell, support ring, plug screw, balance weight, right spindle nose is characterized in that: the cross section of left end socket, right end socket, its middle part is tabular, and the dull and stereotyped excircle in middle part to the excircle that is connected with cylindrical shell is the circular arc concave shape; On the flat board of the middle part of left end socket, right end socket, be respectively equipped with the centre bore seat, on the centre bore seat, be connected with left spindle nose, right spindle nose respectively, on the circular arc concave surface of left end socket, be provided with hand hole seat, vacuum valve seat, on the circular arc concave surface of right end socket, be provided with plug screw, balance weight.

The utility model beneficial effect compared with prior art:

This end socket has been concentrated the advantage of butterfly end socket and flat-plate closure, has overcome the existing shortcoming of butterfly end socket and flat-plate closure.Have the end socket wall thickness little with bearing between characteristics such as to be connected that spindle nose is short, the supporting force-bearing situation is good, technology is conducted heat even, have higher engineering using value.

Fig. 2 is a schematic diagram of the present utility model;

Fig. 3 is the schematic diagram of butterfly end socket;

Fig. 4 is the schematic diagram of flat-plate closure.

Among the figure:

1. hand hole seat, 2. left spindle nose, 3. left end socket, 4. vacuum valve seat, 5. cylindrical shell, 6. support ring, 7. plug screw, 8. balance weight, 9. right end socket, 10. right spindle nose.

The specific embodiment:

Describe the utility model in detail below in conjunction with accompanying drawing:

As shown in Figure 1, this S type end socket stainless steel drying cylinder comprises hand hole seat 1, left spindle nose 2, vacuum valve seat 4, cylindrical shell 5, support ring 6, plug screw 7, balance weight 8, right spindle nose 10.The cross section of left side end socket 3, right end socket 9, its middle part is tabular, and the dull and stereotyped excircle in middle part to the excircle that is connected with cylindrical shell 5 is the circular arc concave shape.The middle part of end socket to excircle that cylindrical shell 5 is connected between cross section seemingly be " S " shape; On the middle part flat board of left end socket 3, right end socket 9, be respectively equipped with the centre bore seat, on the centre bore seat, be connected with left spindle nose 2, right spindle nose 10 respectively, on the circular arc concave surface of left end socket 3, be provided with hand hole seat 1, vacuum valve seat 4, on the circular arc concave surface of right end socket 9, be provided with plug screw 7, balance weight 8.

This S type end socket stainless steel drying cylinder is through Nanjing University of Technology's machinery and the test of power engineering institute, and according to GB150-1998 " GB150-1998 " and " safe technology of pressure vessel supervision rules ", Φ 800S type drying cylinder hydrostatic test strength assessment is qualified.
