Abstract
The utility model belongs to the technical field of quenching thermal treatment equipment and specifically relates to a bell heat preservation outside backplate, including the backplate body, the backplate body is connected with the bell organism, and circumference evenly is provided with the upper bracket on the backplate body respectively, and every upper bracket correspondence is provided with a lower carriage, is provided with the heat preservation between upper bracket and the lower carriage. The utility model discloses can avoid the bell to keep warm the surface of outside backplate and pile up the carbon black, reduce the corruption of carbon black to the outside backplate, prolong the life-span of outside backplate, reduce cost of maintenance.
Description
Technical Field
The utility model relates to the field of quenching heat treatment equipment, in particular to a furnace cover heat preservation outer side guard plate.
Background
In the prior art, furnace cover heat preservation outside guard plates of domestic and foreign manufacturers generally adopt three forms of guard plate punching, guard plate expansion joint opening or furnace cover heat preservation heat-resistant steel plate wrapping to reduce the deformation of the outside guard plate, but can not prevent the carbon black accumulation on the surface of the outside guard plate and can not reduce the heat loss between the outside guard plate and a furnace tank. The carbon black corrodes the guard plate, not only increases the outage rate, has still increased cost of maintenance.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a simple structure prevents that outside backplate warp, energy-concerving and environment-protective bell heat preservation outside backplate.
The utility model adopts the following technical scheme:
the utility model provides a bell heat preservation outside backplate, includes the backplate body, and the backplate body is connected with the bell organism, evenly is provided with the upper bracket on the backplate body respectively circumference, and every upper bracket corresponds and is provided with a lower carriage, is provided with the heat preservation between upper bracket and the lower carriage.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses the surface does not have the carbon black to pile up, has alleviateed the corruption of carbon black to the outside backplate, and increase maintenance cycle reduces the outage rate, has reduced cost of maintenance.
Further, the utility model discloses a following preferred scheme:
the upper bracket and the lower bracket are both L-shaped structures formed by bending steel plates, and are symmetrical structures; two risers and backplate body welded fastening, the heat preservation is arranged in between two diaphragms.
A stop lever is arranged between the upper bracket and the lower bracket and penetrates through the heat-insulating layer.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of portion A of FIG. 1;
in the figure: a furnace lid base body 1; furnace cover heat preservation material 2; a furnace tank 3; a guard plate body 4; an upper bracket 5; a heat-insulating layer 6; a stop lever 7; a lower bracket 8; a transverse plate 9; a riser 10.
Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
The utility model provides a bell keeps warm outside backplate, includes backplate body 4, and the outside of bell insulation material 2 is arranged in to the backplate body, and backplate body 4 sets up and bell body 1's top and bell base member 1 welding as an organic whole around bell base member 1 annular.
An upper support 5 is uniformly arranged on the outer circumference of the guard plate body 4, a lower support 8 is correspondingly arranged below each upper support 5, and the lower supports 8 and the upper supports 5 are symmetrically arranged. The upper bracket 5 and the lower bracket 8 are respectively of an L-shaped structure formed by bending a stainless steel plate, the vertical plates of the upper bracket 5 and the lower bracket 8 are respectively welded with the outer side surface of the guard plate body 4, the transverse plate 9 of the upper bracket 5 and the transverse plate 9 of the lower bracket 8 are arranged in parallel, and the central position of each transverse plate 9 is respectively provided with a through hole for inserting the stop lever 7.
A heat insulation layer 6 is arranged between the transverse plate 9 of the upper bracket 5 and the transverse plate 9 of the lower bracket 8, the heat insulation layer 6 is a ceramic fiber rope (also called a packing) in the embodiment, and the transverse plate 9 of the upper bracket 5 and the transverse plate 9 of the lower bracket 8 are respectively pressed corresponding to the top end and the bottom end of the heat insulation layer 6 to prevent the heat insulation layer 6 from falling off between the upper bracket and the lower bracket. In order to better fix the heat-insulating layer 6 between the upper bracket and the lower bracket, the stop lever 7 penetrates through the heat-insulating layer 6, and two ends of the stop lever 7 respectively penetrate through the transverse plates 9 of the upper bracket and the lower bracket and are fixedly welded with the transverse plates 9.
In this embodiment, the height of the insulating layer 6 needs to be determined according to the height of the guard plate body 4, and the distance between the upper bracket 5 and the lower bracket 8 needs to be determined according to the height of the insulating layer 6.
The gear lever 7 in the embodiment can be replaced by a steel plate, the steel plate is arranged on the outer side of the heat-insulating layer 6, the upper edge and the lower edge of the steel plate are respectively welded and fixed with the upper support 5 and the lower support 8, and the heat-insulating layer is fixed between the steel plate and the guard plate body 4.
The utility model discloses the surface that makes backplate body 4 does not have the carbon black to pile up, has alleviateed the corruption of carbon black to the outside backplate, has prolonged the life of outside backplate, has also reduced the maintenance number of times simultaneously, has reduced cost of maintenance, has reduced the outage rate of equipment, reduces the heat-conduction between outside backplate and the retort 3, has reduced the deformation of outside backplate, and is energy-concerving and environment-protective, and the application space is extensive.
The above is only the concrete embodiments of the present invention, but the protection of the present invention is not limited to this, and all the equivalent changes or replacements proposed to the technical features of the present technical solution, which can be considered by those skilled in the art, are included in the protection scope of the present invention.
