In the production and maintenance process of the high-temperature furnace, the furnace door needs to be opened and closed frequently. In the process of opening and closing the furnace door, the end face of the heat-insulating cylinder is easy to be impacted, and after long-term use, the defects of collision, cracks and the like can be generated, so that the sealing of a thermal field is not tight, the heat-insulating effect is further poor, the energy consumption of equipment is increased, and the maintenance cost is increased.
The utility model aims at the problems existing in the prior art, and provides a hard carbon felt heat preservation cylinder end surface protection device.
The utility model discloses the technical scheme who adopts does:
the end face protection device for the hard carbon felt heat-insulating cylinder comprises a carbon/carbon clamping groove and a fastener for fixing the carbon/carbon clamping groove, wherein the carbon/carbon clamping groove is formed by splicing n sections, and n is an integer larger than or equal to 1.
Furthermore, the carbon/carbon clamping groove is composed of two surfaces, wherein one surface is a plane, and the other surface is a circular arc surface.
Further, when the carbon/carbon clamping groove is matched with the hard carbon felt heat-insulating cylinder for installation, the plane of the carbon/carbon clamping groove is matched with the end face of the hard carbon felt heat-insulating cylinder; the arc surface of the carbon/carbon clamping groove is matched with the inner wall of the hard carbon felt heat-insulating cylinder.
Furthermore, the carbon/carbon clamping groove is matched with the hard carbon felt heat-insulating cylinder and then fixed by a fastener.
Further, the fastener is composed of a bolt and a nut.
Further, when the fastener is installed, the bolt vertically penetrates through the inner wall of the hard carbon felt heat-insulating cylinder, and two ends of the bolt are fixed by nuts.
Furthermore, the fastening piece is made of carbon/carbon or graphite.
Further, the hard carbon felt heat preservation cylinder is preferably a PAN (Polyacrylonitrile) base hard felt heat preservation cylinder, a viscose base hard felt heat preservation cylinder or a pitch base hard felt heat preservation cylinder.
The beneficial effects of the utility model reside in that:
(1) the utility model discloses the intensity of the carbon/carbon draw-in groove among the protector is far above the heat preservation section of thick bamboo of stereoplasm carbon felt, uses behind this carbon/carbon draw-in groove, and heat preservation section of thick bamboo terminal surface is not fragile to obviously prolonged the life of a heat preservation section of thick bamboo, the experiment shows, the utility model discloses a protector can make the life of a heat preservation section of thick bamboo prolong 36~42 months by 24~30 months.
(2) The utility model discloses protector's carbon/carbon draw-in groove generally comprises a complete circle by n (n is greater than or equal to 1) lamella, and reuse carbon/carbon bolt or graphite bolt are fixed to a heat preservation section of thick bamboo terminal surface, and the installation/change is convenient.
