Embodiment 1

[0022] Such as figure 1 As shown, the intelligent high-temperature furnace of the present invention includes an electric cabinet box 8 connected in sequence, a dedicated transformer 17 for smelting, and a high-temperature furnace device. The high-temperature furnace device includes a high-temperature furnace body and a furnace cover 5, and the high-temperature furnace body includes The shell layer 1 arranged on the outside and the high temperature resistant layer 4 arranged on the inside; a high temperature heating rod 6 extending into the high temperature furnace body is provided at the bottom of the furnace cover 5, and a The terminal 7 connected with the high-temperature heating rod 6; the terminal 7 is connected with the special transformer 17 for smelting, and the special transformer 17 for smelting is connected with the electric cabinet 8. In the intelligent high-temperature furnace of the present invention, through the cooperation of the electric cabinet, special transf...

Embodiment 2

[0024] On the basis of the above embodiments, in order to further better implement the present invention, a second high temperature resistant layer 3 is arranged between the outer shell layer 1 and the high temperature resistant layer 4, and the second high temperature resistant layer 3 A transition layer 2 is arranged between the shell layer 1 and the outer shell layer 1. The setting of the second high temperature resistant layer 3 can achieve further high temperature resistance. Preferably, the high temperature resistant layer 4 and the furnace cover 5 are both made of high temperature mullite bricks. Mullite bricks have a high refractoriness, which can reach above 1790 °C. Load softening start temperature is 1600~1700℃. The compressive strength at room temperature is 70-260MPa. It has good thermal shock resistance and is lightweight.

[0025] Preferably, the second high-temperature-resistant layer 3 is made of high-alumina bricks. The high-alumina bricks contain more Al...

Embodiment 3

[0028] On the basis of the above embodiments, in order to further and better implement the present invention, the outer shell layer 1 is made of steel plate, and the steel plate generally can be 304 stainless steel.

Abstract

The invention relates to cement production equipment, and especially relates to an intelligent high-temperature furnace which is simple in structure and capable of improving clinker heating control precision and clinker quality. The intelligent high-temperature furnace comprises an electric cabinet box, a special smelting transformer and a high-temperature furnace device, wherein the high-temperature furnace device comprises a high-temperature furnace body and a furnace cover, and the high-temperature furnace body comprises a housing layer and a high-temperature-resistant layer; a high-temperature heating rod stretching into the high-temperature furnace body is arranged at the bottom of the furnace cover, and a binding post connected with the high-temperature heating rod is arranged at thetop of the furnace cover; and the binding post is connected with the special smelting transformer, and the special smelting transformer is connected with the electric cabinet box. According to the intelligent high-temperature furnace, raw materials are placed in the high-temperature furnace body, the furnace cover covers the high-temperature furnace body, the high-temperature heating rod makes full contact with the raw materials, and the high-temperature heating rod heats according to the set time and the set temperature through control of the electric cabinet box and voltage conversion of the special smelting transformer; and the intelligent high-temperature furnace has the characteristics of being simple in structure and capable of improving clinker heating control precision and clinkerquality.

Description

technical field [0001] The invention relates to cement production equipment, in particular to an intelligent high-temperature furnace with simple structure, improved clinker heating control precision and clinker quality. Background technique [0002] Cement clinker is a semi-finished product obtained by using limestone, clay, and iron as the main raw materials, which are prepared into raw meal in an appropriate proportion, burned until part or all of it is melted, and cooled. In the cement industry, the most commonly used Portland cement clinker is mainly composed of calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide. The main mineral composition is tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite. Portland cement clinker and appropriate amount of gypsum are ground together to form Portland cement. [0003] In the cement production process, the processing from raw material to clinker is an essenti...
