Abstract
The utility model discloses a charcoal is plain calcines rotary kiln lining, especially relates to a plain rotary kiln lining that calcines of charcoal is with prefabricated brick. A plain rotary kiln lining that calcines of charcoal is with prefabricated brick which the structure as follows: high temperature resistant layer becomes the prefabricated brick body with the thermal -insulated heat preservation complex of light, is provided with anchor nail subassembly among the thermal -insulated heat preservation of high temperature resistant layer and light, has respectively seted up a semicircular groove at the both sides face on high temperature resistant layer, and the recess is logical long setting of length direction along high temperature resistant layer. The utility model discloses at the anchor nail subassembly that prefabricated brick internal portion set up, strengthened the bulk strength of prefabricated brick, prevent its under the high temperature state and in the kiln material erode down, cause the phenomenon that prefabricated brick is broken, drop, improved the performance of prefabricated brick, the increase kiln inside lining life -span, greatly reduced the construction degree of difficulty.
Description
Technical field
The utility model relates to a kind of carbon-calcining rotary kiln lining, especially relates to a kind of carbon-calcining rotary kiln lining preformed bricks.
Background technology
The refractory lining of carbon-calcining rotary kiln is the working face carried out in high-temperature calcination refinery coke production, and for bearing the main structure of high temperature, it generally adopts refractory castable to become at the metal cylinder internal casting being welded with heating resisting metal anchoring part. Liner, when casting and constructing, is divided equal equal portions along kiln body radial direction, props up mould casting respectively along kiln body length direction by the mould material liner of existing rotary kiln. Due to the casting and constructing of lead-in in each equal portions and the difference of setting time, between lining equal-dividing bar, form logical seam, make rotary kiln refractory lining globality poor. In the production process that rotary kiln is long-term, refractory lining is in the condition of high temperature for a long time, due to the refractory lining volume change that thermal expansion causes, finally easily causes refractory lining to break and even comes off, thus affect the work-ing life of rotary kiln. This kind of integrated poured difficulty of construction in scene is big simultaneously, labour intensity height, erection formwork cost height.
Summary of the invention
The utility model is in order to solve above technical problem, it is provided that a kind of carbon-calcining rotary kiln lining preformed bricks, it is intended that solve the technical problem that existing carbon-calcining rotary kiln lining globality is poor, intensity is low, life-span of kiln liner is short, difficulty of construction is big.
For achieving the above object, the utility model adopts following technical scheme to realize:
A kind of carbon-calcining rotary kiln lining preformed bricks, its structure is as follows: high-temperature-resistant layer and light heat insulating layer are combined into preformed bricks body, it is provided with anchor nails assembly among high-temperature-resistant layer and light heat insulating layer, respectively offered a semi-circular recesses in the two sides of high-temperature-resistant layer, groove is the elongated setting of length direction along high-temperature-resistant layer.
Above-mentioned high-temperature-resistant layer is arranged on above light heat insulating layer.
The material of above-mentioned high-temperature-resistant layer selects low cement mullite pouring material.
The material of above-mentioned light heat insulating layer selects light mullite pouring material or alumina bubble castable.
The material of above-mentioned anchor nails assembly is high temperature resistant stainless steel 0Cr25Ni20.
Above-mentioned anchor nails assembly is symmetrical structure, it is made up of the round steel of the weldment and connection two weldments that are positioned at both sides, round steel is welded on two weldment middle position, and two weldments are separately positioned on the both sides that preformed bricks body inside goes up symmetry axis along its length.
Above-mentioned weldment is welded with the 2nd U-shaped anchor nails being positioned at lower end by the first U-shaped anchor nails being positioned at upper end.
The first above-mentioned anchor nails is less than the 2nd anchor nails size.
Owing to adopting technique scheme, the utility model tool being has the following advantages and effect:
The anchor nails assembly that the utility model is arranged in preformed bricks body inside, strengthen the bulk strength of preformed bricks, prevent it at high operating temperatures and under material washes away in kiln, cause the phenomenon that preformed bricks is broken, come off, improve the use properties of preformed bricks, increase the kiln liner life-span, greatly reduce difficulty of construction.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1, a kind of carbon-calcining rotary kiln lining preformed bricks of the utility model, its structure is as follows: high-temperature-resistant layer 1 and light heat insulating layer 2 are combined into preformed bricks body, high-temperature-resistant layer 1 is arranged on above light heat insulating layer 2, it is provided with anchor nails assembly 3 among high-temperature-resistant layer 1 and light heat insulating layer 2, respectively offered a semi-circular recesses 4 in the two sides of high-temperature-resistant layer 1, groove 4 is the elongated setting of length direction along high-temperature-resistant layer 1.
The material of above-mentioned high-temperature-resistant layer 1 selects low cement mullite pouring material. The material of light heat insulating layer 2 selects light mullite pouring material or alumina bubble castable. The material of anchor nails assembly is high temperature resistant stainless steel 0Cr25Ni20.
As shown in Figures 2 and 3, anchor nails assembly 3 is symmetrical structure, it is made up of the round steel 7 of the weldment and connection two weldments that are positioned at both sides, round steel 7 is welded on two weldment middle position and forms an one-piece construction, anchor nails unit construction is fixed, can better strengthening the bulk strength of preformed bricks, two weldments are separately positioned on the both sides that preformed bricks body inside goes up symmetry axis along its length. Weldment is welded with the 2nd U-shaped anchor nails 6 being positioned at lower end by the first U-shaped anchor nails 5 being positioned at upper end. The size of the first anchor nails 5 to the two anchor nails 6 is little, and such anchor nails unit construction can better improve the bulk strength of preformed bricks body so that globality is better.
