Abstract
The utility model discloses a rotary kiln mouth structure. The port of the big kiln cylindrical body is provided with a loop of armor plate of the kiln mouth which is provided with inclined plane by the utility model. And the armor plate of the kiln mouth is connected with the big kiln cylindrical body through a bolt. The utility model is provided with some advantages, as simple structure, convenient maintenance, safe in use, reliability, long service life, strong interchangeability, convenient to clean and no abscission, and can not create slip of scores of metre fire-clay brick inside the kiln relative to the kiln cylindrical body because of the kiln mouth. Using the utility model can improve 20-30% of running rate of kiln, improves almost 10-20% of deliverability of entire kiln system per machine-hour, improves almost 10 times of service life, and largely drops down overhauling frequency, and greatly reduces operating cost of system.
Description
Technical field:
The utility model relates to a kind of rotary kiln mouth structure, particularly a kind of horizontal revolving kiln kiln mouth structure.
Background technology:
At present, rotary kiln mouth structure form in the prior art has varied, and structure commonly used has: check ring for blocking bricks and reinforced concrete structure and the type kilneye backplate firebrick structure that easily comes off.The rotary kiln kilneye of these structures mainly exist in process of production service life short, yielding, kilneye firebrick and kiln front cylinder firebrick easily come off, overhaul shortcomings such as the cleaning difficulty is big, expense is high, the time between overhauls(TBO) is long, seriously influenced the running efficiency and the Tai Shi production capacity of whole system equipment.Therefore the result of use of existing rotary kiln mouth structure still is not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide all rotary kiln mouth structures easily of a kind of simple in structure, long service life, installation and maintenance, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises the big kiln cylinder body of rotary kiln (1) and built refractory brick (2) by laying bricks or stones in big kiln cylinder body (1), port at big kiln cylinder body (1) is placed with the bevelled kilneye backplate of an astragal (3), and kilneye backplate (3) is connected on the big kiln cylinder body (1) by bolt (4); All be provided with a draw-in groove (a) in the bottom of every kilneye backplate (3), and be welded with a kilneye back-up ring (5) on the circle in the port of big kiln cylinder body (1), the draw-in groove (a) of every kilneye backplate (3) all is stuck on the kilneye back-up ring (5); On the big kiln cylinder body (1) between kilneye backplate (3) and the refractory brick (2), also built the high brick layer of one deck backgauge (6) by laying bricks or stones; A circle kilneye backplate (3) that is arranged in big kiln cylinder body (1) port has the inclined-plane by 15～30 and kilneye backplate that adopt the high temperature resistant rare earth material of 3Gr2Mn8Ni4SiNRc to make is formed.
Owing to adopted technique scheme, the utility model compared with prior art, the utlity model has advantages such as simple in structure, easy to maintenance, safe in utilization, reliable, long service life, interchangeability is strong, cleaning makes things convenient for, do not come off, and the utility model can not cause tens meters relative kiln cylinder body slippages of firebrick in the kiln because of the kilneye problem.When the utility model is worked, solid size block particle rotates downward slippage, wanders, impacts with the kiln body, and kilneye backplate of the present utility model and the high brick of backgauge can play the effect of high temperature resistance (about 1000 ℃), resistance to high temperature oxidation, high temperature resistance wearing and tearing, high temperature deformation resistance simultaneously.Because kiln mouth structure of the present utility model is reasonable, make in its kiln tens meters firebricks not relatively the cylindrical shell slippage cause brick red kiln influence production.Thereby prevented that each section of kiln cylindrical shell from falling the brick temperature distortion, guaranteed the linearity of kiln long-term operation, thoroughly improved the technology status of traditional rotary kiln body, make the running rate of kiln improve 20～30%, production capacity improves about 10 ~ 20% when making whole kiln system platform, improve about 10 times its service life, and the big radian of the maintenance frequency is descended, and greatly reduces the operating cost of system.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: directly on the basis of the big kiln cylinder body (1) of existing horizontal revolving kiln, change a social system, during making, the circle of arranging on the front port of the big kiln cylinder body (1) of building refractory brick (2) by laying bricks or stones has inclined-plane (b) and kilneye backplate (3) that adopt the high temperature resistant rare earth material of 3Gr2Mn8Ni4SiNRc to make by 15～30, for easy to make, preferably determine every size that has the kilneye backplate (3) on inclined-plane by 24 modes that are arranged into an annulus circle, every kilneye backplate (3) all is connected on the big kiln cylinder body (1) by two bolts (4) respectively, when making kilneye backplate (3), produce a draw-in groove (a) simultaneously in its bottom, and circle is gone up a welding kilneye back-up ring (5) in the port of big kiln cylinder body (1), and the draw-in groove (a) of every kilneye backplate (3) all is stuck on the kilneye back-up ring (5); Big kiln cylinder body (1) between kilneye backplate (3) and refractory brick (2) is gone up and to be built the high brick layer of one deck backgauge by laying bricks or stones with concrete or other resistant to elevated temperatures material and (6) at last.
Claims (4)
1, a kind of rotary kiln mouth structure, it comprises the big kiln cylinder body of rotary kiln (1) and built refractory brick (2) by laying bricks or stones in big kiln cylinder body (1), it is characterized in that: the port at big kiln cylinder body (1) is placed with the kilneye backplate (3) that an astragal has inclined-plane (b), and kilneye backplate (3) is connected on the big kiln cylinder body (1) by bolt (4).
2, rotary kiln mouth structure according to claim 1, it is characterized in that: all be provided with a draw-in groove (a) in the bottom of every kilneye backplate (3), and be welded with a kilneye back-up ring (5) on the circle in the port of big kiln cylinder body (1), the draw-in groove (a) of every kilneye backplate (3) all is stuck on the kilneye back-up ring (5).
