In order to realize the purpose, the utility model discloses a technical scheme is:

a lime kiln fire port reforming device comprises a kiln body, a fire port arranged on the kiln body, a steel plate and a connecting pipe; the connecting pipe is positioned above the fire port and communicated with the interior of the kiln body through the fire port; the steel plate is positioned above the connecting pipe and covers the connecting pipe.

Further, a temperature-resistant layer is coated on the inner wall of the connecting pipe.

Furthermore, the thickness of the temperature-resistant layer is 3-6 cm.

Further, the connecting pipe is a stainless steel pipe; the temperature resistant layer is a thick mullite castable layer.

Furthermore, the lime kiln fire port reforming device also comprises a fixing layer wrapped on the outer wall of the connecting pipe; and the fixed layer is respectively contacted with the kiln body and the steel plate.

Further, the fixed layer is a mullite pouring material layer.

Furthermore, the lime kiln fire port reforming device further comprises heat insulation layers arranged between the connecting pipe and the steel plate and between the fixing layer and the steel plate.

Furthermore, the heat-insulating layer is a heat-insulating cotton layer.

The beneficial effects of the utility model are that:

1. the utility model discloses set up the connecting pipe on berthing the burner, the steel sheet lid realizes sealedly on the connecting pipe. The reaction air flow in the kiln body is not directly contacted with the steel plate, the steel plate is not easy to deform, and the sealing property is improved. Furthermore, a temperature resistant layer is coated on the inner wall of the connecting pipe, the thickness of the temperature resistant layer is 3-6 cm, the temperature resistant layer is a thick mullite pouring material layer, the hardness of the connecting pipe can be enhanced, deformation is avoided, and the sealing performance is better.

2. The utility model also comprises a fixed layer wrapped on the outer wall of the connecting pipe; and the fixed layer is respectively contacted with the kiln body and the steel plate, the fixed layer is a mullite pouring material layer, the hardness of the connecting pipe is improved from the outside of the connecting pipe, the connecting pipe is not deformed, and the steel plate can be in sealing contact with the connecting pipe.

3. The utility model discloses still including setting up the heat preservation between connecting pipe and steel sheet and between fixed bed and the steel sheet. The heat preservation layer is a heat preservation cotton layer, the sealing performance of the steel plate and the connecting pipe is enhanced, the fire hole is not leaked, and the working condition in the kiln stably runs.

Drawings

FIG. 1 is a schematic view of a fire port reforming device provided by the present invention;

in the figure:

1-steel plate; 2, insulating layer; 3-temperature resistant layer; 4, connecting pipes; 5-a fixed layer; 6-mooring fire hole; 7-kiln body.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Examples

Referring to fig. 1, a lime kiln fire port reforming device comprises a kiln body 7 and a fire port 6 arranged on the kiln body 7; the steel plate is characterized by also comprising a steel plate 1 and a connecting pipe 4; the connecting pipe 4 is positioned above the fire port 6 and is communicated with the interior of the kiln body 7 through the fire port 6; the steel plate 1 is positioned above the connection pipe 4 and covers the connection pipe 4.

The inner wall of the connecting pipe 4 is coated with a temperature resistant layer 3. The thickness of the temperature resistant layer 3 is 3-6 cm. The temperature resistant layer 3 is a thick mullite castable layer. The connecting pipe 4 is a stainless steel pipe.

The lime kiln fire port reforming device also comprises a fixed layer 5 wrapped on the outer wall of the connecting pipe 4; and the fixed layer 5 is respectively contacted with the kiln body 7 and the steel plate 1. The fixed layer 5 is a mullite castable layer.

The device for reforming the fire hole of the ash kiln further comprises heat-insulating layers 2 arranged between the connecting pipe 4 and the steel plate 1 and between the fixed layer 5 and the steel plate 1. The heat preservation layer 2 is a heat preservation cotton layer.
