Description
Technical Field
The utility model relates to a boiler returning charge ware, especially a boiler is refractory structure for returning charge ware.
Background
The effect of boiler returning charge ware is in the high combustion chamber of pressure is sent back to through the stable back of fluidizing air with the high temperature solid material that the boiler separator separated, nevertheless because solid material when returning along with the air, can cause lasting high temperature impact to the top of returning charge ware, even lead to returning charge ware inner wall to lay the flame retardant coating, also still can receive to erode and corrode wearing and tearing that cause the flame retardant coating and the burning red and the small opening of returning charge ware lateral wall, arouse the ash leakage problem of returning charge ware after long-term the use. When the side wall of the material returning device is damaged, if the material returning device is not maintained in time, holes are gradually enlarged, the returning stability of solid materials is reduced, and certain potential safety hazards exist; and the refractory layer for repairing the inner wall of the material returning device needs to be subjected to furnace shutdown treatment, so that great economic loss is caused. Therefore, a structure capable of repairing the damaged portion of the return feeder without stopping the furnace is required.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a boiler is refractory structure for returning charge ware. The repair device can repair the damaged part of the material returning device under the condition of not stopping the furnace.
The technical scheme of the utility model: the utility model provides a boiler is refractory structure for returning charge ware, includes flue gas pipe, returning charge ware and the returning charge pipe that connects gradually, and the inner wall of returning charge ware is equipped with refractory material layer, and the outside of returning charge ware is equipped with the fixed bolster, forms between the outer wall of fixed bolster and returning charge ware and fills the cavity, and the inner wall of filling the cavity is equipped with the shrouding all around, fills to be filled with and pours the refractory material layer in the cavity, fills the cavity top and is equipped with the mouth of placing with outside intercommunication.
In the refractory structure for the boiler return feeder, the refractory material layer is made of refractory bricks.
In the refractory structure for the boiler returning device, an asbestos cushion layer is laid on one side of the filling cavity close to the returning device, and the periphery of the asbestos cushion layer is attached to the sealing plate.
In the refractory structure for the boiler material returning device, the fixed support is formed by connecting a plurality of section steels, and the fixed support is annularly sleeved on the outer side of the material returning device.
Compared with the prior art, the utility model can form a filling cavity which completely covers the damaged part outside the material returning device through the matching of the fixed support and the closing plate after the outer wall of the material returning device is damaged, and realize the repair of the damaged part by pouring the refractory material in the filling cavity, thereby the utility model can maintain the material returning device from the outside without stopping the furnace, and the stability and the service life of the material returning device are improved while the economic loss is avoided; before the pouring refractory material layer is poured, the pouring material can be blocked by the asbestos cushion layer laid on the inner side of the filling cavity, so that the pouring material is prevented from entering the material returning device from a damaged position and affecting the working stability of the material returning device, meanwhile, high-temperature airflow is prevented from being discharged from a pore position to affect the pouring effect, and the repairing effect on the material returning device is effectively improved; through establishing shaped steel from the outside and forming the fixed bolster, can also make the utility model discloses can repair the outside optional position of returning the glassware to need not to support the fixed bolster externally, improved the utility model discloses an applicability. Therefore, the utility model discloses can repair the damaged department of returning the glassware under the condition of not blowing out.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an enlarged view of fig. 1 from a.
The labels in the figures are: 1-flue gas pipe, 2-returning charge ware, 3-returning pipe, 4-refractory material layer, 5-fixed support, 6-closing plate, 7-pouring refractory material layer, 8-placing port, 9-asbestos cushion layer.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. The utility model provides a boiler is refractory structure for returning charge ware, constitutes as shown in figure 1, including the flue gas pipe 1 that connects gradually, returning charge ware 2 and returning charge pipe 3, the inner wall of returning charge ware 2 is equipped with refractory material layer 4, and the outside of returning charge ware 2 is equipped with fixed bolster 5, forms between the outer wall of fixed bolster 5 and returning charge ware 2 and fills the cavity, and the inner wall of filling the cavity is equipped with shrouding 6 all around, and the packing cavity intussuseption is filled with pours refractory material layer 7, and the packing cavity top is equipped with the mouth 8 of placing with outside intercommunication.
The material of the refractory material layer 4 is refractory bricks.
An asbestos cushion layer 9 is laid on one side of the filling cavity close to the material returning device 2, and the periphery of the asbestos cushion layer 9 is mutually attached to the sealing plate 6.
The fixed support 5 is formed by connecting a plurality of section steels, and the fixed support 5 is annularly sleeved on the outer side of the material returning device 2; the maintenance personnel can adjust the interval and the joint position between the fixed bracket 5 and the material returning device 2 according to the damaged position.
The utility model discloses a theory of operation: when the side wall of the material returning device 2 is damaged due to high-temperature impact, a maintenance worker firstly installs the fixing support 5 according to the damaged position, so that the fixing support 5 forms an interval with the damaged position after installation, and other positions are kept attached. Fixed bolster 5 is after supporting the location, set up shrouding 6 around the damaged position, lay asbestos bed course 9 on the outer wall surface of returning glassware 2 simultaneously, make to form the cavity of pouring of relative sealed between asbestos bed course 9 and the shrouding 6, pour refractory material at last and pour from placing mouthful 8 and pour into, make it can wrap up returning glassware 2 in the damaged department after pouring the shaping, effectively avoid leaking the ash and the expansion problem of damaged position, the job stabilization nature of returning glassware 2 and the economic benefits of producer have been guaranteed.
