Wherein, the top end face border department rigid coupling of end cover body has L type overhanging piece.
Wherein, be equipped with the asbestos pad between end cover body and the L type overhanging piece.
Wherein, the heat insulation layer is superfine glass wool or light silicate.
The end cover body is made of cast iron materials.
The end cover body and the reinforcing ribs are fixedly connected in an integrally pouring mode.
The utility model has the advantages that: the utility model provides an end cover for papermaking dryer is through setting up the strengthening rib to strengthened the structural strength of end cover body, axle sleeve and two adjacent strengthening ribs enclose into an accommodation space jointly, and add in this accommodation space and have the insulating layer that keeps warm, reduce thermal scattering and disappearing, reduce the energy consumption, reduce manufacturing cost.

Description of the drawings: the end cover comprises an end cover body 1, a boss 2, an L-shaped extending piece 3, an asbestos pad 4, reinforcing ribs 5 and a shaft sleeve 6.
Detailed Description
The invention will be further described with reference to the following examples.
The utility model discloses a concrete implementation mode of end cover for papermaking dryer, as shown in figure 1, including end cover body 1, the middle part of end cover body 1 is formed with axle sleeve 6, and the top surface in the end cover body 1 is equipped with a plurality of strengthening ribs 5 that use the centre of a circle of end cover body 1 to arrange as central circumference interval. In this embodiment, the end cap body 1 and the reinforcing rib 5 are fixedly connected by integral casting, and may be prepared by casting using cast iron material. The mode that adopts integrative pouring can further improve the structural strength of end cover body 1, and is effectual than the welding. The strengthening rib 5 not only can strengthen the structural strength of end cover body 1, and end cover body 1, axle sleeve 6 and every two adjacent strengthening ribs 5, the outer wall of axle sleeve 6 and the inside wall of end cover body 1 enclose into an accommodation space jointly, and add in every accommodation space and have the thermal-insulation layer, it has the thermal-insulation layer to fill between two adjacent strengthening ribs 5 promptly, thereby make the inboard of whole end cover form the thermal-insulation structure that keeps warm, reduce thermal scattering and disappearing, reduce the energy consumption, reduce manufacturing cost.
The cylinder body of the existing drying cylinder is generally tubular, the two end parts of the cylinder body are respectively provided with an end cover, and under the action of internal pressure, the rigidity difference between the end cover body and the cylinder body is large, so that the strain in a discontinuous structure area is overlarge. In the present embodiment, in order to further improve the connection strength between the end cover body 1 and the cylinder body, the bottom end surface of the end cover body 1 is provided with an annular boss 2, and the peripheral side surface of the boss 2 is fixedly connected to the bottom end portion of the end cover body 1. The joint of the end cover body 1 and the cylinder body is made into a convex shape so as to relieve the overlarge rigidity of the area. The drying cylinder with the convex end cover body 1 can improve the speed of the drying cylinder, increase the use pressure and the width of the drying cylinder, and has the advantages of reducing the cost, improving the economic efficiency, lightening the quality of the drying cylinder and the like.
In order to facilitate the connection of the end cover body 1 and the cylinder body of the drying cylinder, a plurality of mounting holes which are circumferentially arranged at intervals by taking the circle center of the end cover body 1 as the center are formed in the edge of the end cover body 1. In order to solve the problem of thermal stress concentration, the top end face edge of the end cover body 1 is fixedly connected with the L-shaped extending piece 3, and the L-shaped extending piece 3 and the end cover body 1 are of mutually independent structures, so that the safety of the drying cylinder can be improved. An asbestos pad 4 is arranged between the end cover body 1 and the L-shaped extending part 3, so that heat loss of the end cover body 1 can be further reduced.
As the preferred scheme, the heat-insulating layer is superfine glass wool or light silicate, the material cost is low, and the heat-insulating effect is good. Superfine glass wool or light silicate belongs to the existing materials.
The end cover for the papermaking dryer of this embodiment is through setting up strengthening rib 5 to strengthened the structural strength of end cover body 1, axle sleeve 6 and two adjacent strengthening ribs 5 enclose into an accommodation space jointly, and add in this accommodation space and have the thermal insulation layer, reduce thermal scattering and disappearing, reduce the energy consumption, reduce manufacturing cost.
