Problems solved by technology

[0004] Conventional manhole doors have 20 fastening bolts. The asbestos rope used for sealing is irregular, the sealing effect is poor, and the strength of the asbestos rope is low, so it cannot be reused. If the winding is not careful, it will easily cause smoke leakage, dust, and installation and disassembly time. Long, labor-intensive, poor working environment due to operation leakage, affecting system stability and wasting energy

Embodiment Construction

[0027] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0028] Such as Figure 1 to Figure 7 As shown,

[0029] A stretched pressure type flexible sealed manhole door, comprising a door frame 1, with a pressing edge 5 on the edge of the door frame 1, a corresponding door panel 3 is provided on the outside of the door frame 1, and a flexible sealing bead 2 is fixedly connected to the inside of the door panel 3. The bead 2 is in airtight contact with the blanking edge 5. The outer surface of the door panel 3 is fixedly connected with a rigid beading 8 which corresponds to the inner and outer blanking edges 5 of the door frame 1. The outer surface of the rigid beading 8 is recessed with a plurality of pressing grooves. 11. A rigid clamp 7 is provided where the stretched groove 11 is ...

Abstract

The invention provides a stretching and pressing type flexible sealing manhole door. A flexible sealing pressing strip is fixedly connected into a door slab and makes contact with a pressing edge in a closed mode. A rigid pressing strip is fixedly connected to the outside of the door slab by a circle and corresponds to the pressing edge of a door frame inside and outside. The outer surface of the rigid pressing strip is provided with a plurality of stretching and pressing grooves in an inward concave mode. The positions where the stretching and pressing grooves are located are provided with rigid hoops which are in a U shape. The pressing edge of the door frame, the flexible sealing pressing strip, the edges of the door slab and the rigid pressing strip are jointly clamped into a space defined by the rigid hoops which are in threaded connection with stretching and pressing bolts. The free ends of the stretching and pressing bolts are located in the stretching and pressing grooves and outwards obliquely stresses the rigid pressing strip relative to the center of the door slab. The free ends of the stretching and pressing bolts are conical. The bottom walls of the stretching and pressing grooves are also conical. The contact points between the free ends of the stretching and pressing bolts and the stretching and pressing grooves outwards deviate from the centers of the bottom walls of the stretching and pressing grooves relative to the center of the door slab.

Description

Technical field [0001] The invention relates to a matching device for a boiler, in particular to a stretching type flexible sealing manhole door. Background technique [0002] The circulating fluidized bed boiler is equipment used in industrial and mining enterprises. The flue gas system is the main component of the normal operation of the boiler. The layout is more complicated. With the increase in the layout and installation of environmentally friendly and energy-saving functional equipment, the supporting installation is checked The number of manhole doors for maintenance has also increased significantly. [0003] The size of the manhole door of the conventional boiler flue gas system is 450mm*450mm. The door cover and the flange frame are fastened by bolts, and the joint surface is filled with asbestos rope for sealing. [0004] Conventional manhole doors have 20 fastening bolts, the asbestos rope used for sealing is irregular, the sealing effect is poor, and the strength of the...
