Description

A heat insulation device for repairing the bottom of coke oven

technical field

The utility model belongs to a heat insulation device, in particular to a heat insulation device for maintaining the bottom of a coke oven.

Background technique

The bottom of the clean heat recovery coke oven is made of silica brick or high-carbon silicon castable bottom. Under high temperature conditions, their resistance to sudden temperature changes is poor, and the bottom of the furnace is prone to unevenness. In this way, during the coal charging process, due to the unevenness of the bottom of the furnace, the coal cake will collapse, which will increase the coking rate. Moreover, during the coking operation of the coke oven, it is often difficult to hang the furnace door and the phenomenon of coke collapse. The normal production operation of the furnace has a great negative impact. Therefore, there is a need to repair damaged coke oven floors. At present, the general maintenance of the bottom of the coke oven needs to stop production after the temperature drops to normal temperature outside the furnace, and then the construction personnel can go in for maintenance. The construction period is long, and after the maintenance is completed, it takes a long time to restore the coke oven to the coking operating temperature , thereby affecting production and causing great economic losses.

Contents of the invention

The purpose of the utility model is to overcome the disadvantages of the above-mentioned prior art, and provide a thermal insulation device that can shorten the maintenance time of the bottom of the coke oven, save energy, and improve production efficiency.

A heat insulation device for repairing the bottom of a coke oven, characterized in that the heat insulation device includes a heat insulation layer 1 and a support frame 2, and the heat insulation layer is installed on the outside of the support frame.

The heat insulation device also includes an operation platform 3, and the operation platform is mounted on the inner side of the support frame.

The heat insulation device is 30-50mm smaller than the frontal volume of the carbonization chamber of the coke oven.

Compared with the prior art, the utility model has the following beneficial effects: it is convenient to operate and has good safety in the process of maintaining the coke oven; it can repair the damaged furnace bottom of the furnace bottom coking chamber without stopping the furnace, and after the maintenance is completed, The operation temperature of the coke oven can be restored quickly, which is beneficial to the normal heating and adjustment of other coking chambers of the coke oven, and also prolongs the service life of the coke oven.

Description of drawings

FIG. 2 is a side view of FIG. 1 .

Detailed ways

As shown in Fig. 1 and Fig. 2, a heat insulation device for maintaining the bottom of a coke oven, the heat insulation device includes a heat insulation layer 1 and a support frame 2, and the heat insulation layer is installed on the outside of the support frame. The heat insulation device also includes an operation platform 3 mounted on the support frame, and the operation platform is mounted on the inner side of the support frame. Usually, the surface volume of the front section of the thermal insulation device is 30-50 mm smaller than the surface volume of the coke oven carbonization chamber 5 .

Working principle of the utility model:

When the utility model is in operation, firstly, the heat insulation device is placed at the mouth of the carbonization chamber 1 of the coke oven that needs maintenance, and the heat insulation layer 1 faces the inside of the carbonization chamber 1 of the coke oven; Platform 3, after heat insulation device is pushed to the length that needs maintenance in carbonization chamber 5, just can repair coke oven bottom brick 4.
