Description

A strong high temperature resistant molten salt furnace

technical field

The utility model relates to a strong and high-temperature-resistant molten salt furnace, which belongs to the field of molten salt furnaces.

Background technique

In the melamine production process, the molten salt furnace is required to provide continuous 385-440 high-temperature heat for the melamine reaction, so the molten salt furnace needs to be continuously operated at high load, but because of the instability of melamine production, it is often necessary to adjust the melamine output, switch, and cut size Mixing, etc., and the matching of the corresponding molten salt furnace also needs to be adjusted frequently, resulting in frequent changes in the furnace temperature, etc., which can easily cause coking in the furnace, cracking of the furnace wall and arch, and even the collapse of the furnace. After the collapse of the furnace, the maintenance of the furnace wall and furnace arch generally takes a long time, so a strong high temperature resistant molten salt furnace is needed to solve the above-mentioned problems.

Contents of the invention

Aiming at the deficiencies of the existing technology, the purpose of this utility model is to provide a strong high temperature resistant molten salt furnace to solve the problems raised in the above background technology. long lasting.

In order to achieve the above object, the utility model is achieved through the following technical solutions: a solid high temperature resistant molten salt furnace, including molten salt furnace body, furnace arch, top beam, furnace wall and bottom beam, the furnace wall is built on The upper end of the bottom beam, the top beam is built on the top of the furnace wall, the furnace arch is installed on the upper end of the top beam, the molten salt furnace body is fixed on the upper end of the furnace arch, and the bottom beam, top beam and furnace arch are all made of high temperature resistant The steel bars, high temperature resistant cement, refractory stones and high temperature resistant steel bars are poured through molds, and the furnace wall is made of refractory bricks.

Further, insulation rock wool is filled between the bottom beam and the furnace wall, between the furnace wall and the top beam, and between the top beam and the furnace arch.

Beneficial effects of the utility model: a solid and high-temperature-resistant molten salt furnace of the utility model, because the utility model adds a furnace arch, a top beam, a furnace wall and a bottom beam, the design directly uses a mold to prefabricate the furnace arch, and because the bottom beam , top beam and furnace arch, the surface of the top beam, furnace wall and bottom beam is smooth enough, so they can expand relatively after being heated and can play a role in heat insulation. After the furnace arch is solidified, use refractory cement and high temperature resistant steel bars to smooth and melt The inner surface of the salt furnace wall ensures the overall firmness and high temperature resistance, and at the same time allows each part to have room for relative movement when the temperature changes, thereby improving reliability and stability.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

Please refer to Figure 1, the utility model provides a technical solution: a solid high temperature resistant molten salt furnace, including molten salt furnace body 1, furnace arch 2, top beam 3, furnace wall 4 and bottom beam 5, the furnace wall 4 is built On the upper end of the bottom beam 5, the top beam 3 is built on the upper end of the furnace wall 4, the furnace arch 2 is installed on the upper end of the top beam 3, the molten salt furnace body 1 is fixed on the upper end of the furnace arch 2, the bottom beam 5, the top beam 3 and the furnace arch 2 are all It is made of high-temperature-resistant steel bars, high-temperature-resistant cement, refractory stones and high-temperature-resistant steel bars through mold pouring. The furnace wall 4 is made of refractory bricks. Beam 5, after bottom beam 5 is solidified, build furnace wall 4 with refractory bricks, then pour top beam 3 with high-temperature-resistant steel bars, high-temperature-resistant cement, refractory stones and high-temperature-resistant steel bars at the furnace wall 4 upper end, treat that top beam 3 is solidified. Then refractory bricks are used to build the furnace arch 2, and the furnace arch 2 is poured directly through high-temperature-resistant steel bars, high-temperature-resistant cement, refractory stones, and high-temperature-resistant steel bars, so that the bottom beam 5, top beam 3 and furnace arch 2 are prefabricated, and the surface is sufficient. It is smooth and flat, and can expand relatively after being heated and can play a role of heat insulation. After the furnace arch 2 is solidified, use refractory cement and high-temperature-resistant steel bars to smooth the inner surface of the furnace wall 4 of the molten salt furnace, and put it into use after the whole is dried in the shade. The overall strong and high temperature resistance performance, and at the same time allow each part to have relative movement space when the temperature changes, so that the reliability and stability are greatly improved, and the service life can reach about five years.

Between the bottom beam 5 and the furnace wall 4, between the furnace wall 4 and the top beam 3, and between the top beam 3 and the furnace arch 2 are all filled with thermal insulation rock wool, which improves the thermal insulation effect and improves the sealing performance.
