Abstract
The utility model relates to a high temperature resistant water cooling rotary kiln door with long service life, comprising a door frame, a door plate and a hinge, wherein the door plate is connected with the door frame through the hinge; and high temperature sides of the door frame and the door plate are provided with refractory material layers. The high temperature resistant water cooling rotary kiln door with the long service life is characterized in that metal structures of the door frame and the door plate are internally and uniformly distributed with cooling water pipes; inlets of the cooling water pipes are arranged on the bottom of the door frame, and outlets of the cooling water pipes are arranged on the top of the door frame; and the cooling water pipes are metal hoses. Compared with the prior art, the high temperature resistant water cooling rotary kiln door has the advantages that the water cooling effect is good; the service life is remarkably prolonged, and the water cooled part has the service life of more than ten years; a refractory material is rammed and poured on the surface of a door body so as to resist high temperature and heat corrosion, so that the use efficiency of the door is improved; and the conventional practice of improving the heat resistance by singly using a heat resistant alloy steel material is avoided, and the manufacture cost is reduced.
Description
Technical field
The utility model relates to and is used for the rotary kiln field that metallurgical briquetting is produced, particularly a kind of high temperature resistance and long life-span water cooling rotary kiln gate.
Background technology
During metallurgical briquetting was produced now, the rotary kiln gate generally used the heat-resisting alloy steel material, to guarantee its resistance to elevated temperatures.When installing before the gate uses on stock retaining wall body surface ramming the thick pouring fireproof material of 200mm, be used for reducing the scaling loss of high temperature like this to the gate.The gate depends on the performance of gate body high-temperature alloy steel and the thickness of surperficial refractory material service life.The working condition at gate is, a side is in 1110 ℃ of high temperature sinterings, and a side is under the natural temperature, and especially in the winter of severe cold, because the temperature difference causes door-plate and doorframe cracking greatly, service life is shorter, and new gate average life is about 3 years.In order to improve the rotary kiln service efficiency, prolong rotary kiln gate service life, according to the actual working conditions of present rotary kiln, must change the resistance to elevated temperatures at rotary kiln gate.
Summary of the invention
The purpose of this utility model provides a kind of high temperature resistance and long life-span water cooling rotary kiln gate, overcomes the deficiencies in the prior art, reduces the destruction of high temperature opposite house body, prolongs the service life at gate.
For solving the problems of the technologies described above, the technical solution of the utility model is:
High temperature resistance and long life-span water cooling rotary kiln gate, comprise doorframe, door-plate, hinge, door-plate is connected with doorframe by hinge, the high temperature side of doorframe and door-plate is provided with refractory masses, in the metal structure of doorframe and door-plate, evenly be placed with cooling water pipe, the doorframe bottom is located in the cooling water pipe import, and the doorframe top is located in outlet.
Described cooling water pipe is a metal hose.
Compared with prior art, the beneficial effects of the utility model are: the water cooling good cooling effect, can significant prolongation gate service life, it is subjected to water cooling part service life more than 10 years, door surface ramming pouring fireproof material, high temperature resistant heat resistanceheat resistant is corroded, and has improved the service efficiency at gate, break away from the simple at present conventional thought that relies on the heat-resisting alloy steel material to improve heat resistance, reduced cost of manufacture.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1-import 2-doorframe 3-gate panel 4-observes door-plate 5-hinge 6-outlet 7-cooling water pipe 8-refractory masses
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, the utility model high temperature resistance and long life-span water cooling rotary kiln gate structure schematic diagram, comprise doorframe 2, gate panel 3, hinge 5, observe door-plate 4, gate panel 3 is connected with doorframe 2 by hinge 5 respectively with observation door-plate 4, the high temperature side of doorframe 2, gate panel 3 and observation door-plate 4 is the thick refractory masses 8 of ramming cast 100mm respectively, in the metal structure of doorframe 2, gate panel 3 and observation door-plate 4, evenly be placed with the cooling water pipe 7 that metal hose is made respectively, doorframe 2 bottoms are located in cooling water pipe import 1, and doorframe 2 tops are located in outlet 6.
Inject cooling water by import 1 during use, cooling water is by cooling water pipe 7, discharge by outlet 6, cooling water can be taken away a big chunk heat of a body, refractory masses 8 can better guarantee that the temperature of cooling water rises slowly, slowed down the rate of heat exchange of cooling water, be drawn into rotary kiln in order to prevent cold air, the binding site at gate also need be provided with better seal.
Claims (2)
1. high temperature resistance and long life-span water cooling rotary kiln gate, comprise doorframe, door-plate, hinge, door-plate is connected with doorframe by hinge, the high temperature side of doorframe and door-plate is provided with refractory masses, it is characterized in that, evenly be placed with cooling water pipe in the metal structure of doorframe and door-plate, the doorframe bottom is located in the cooling water pipe import, and the doorframe top is located in outlet.
2. high temperature resistance and long life-span water cooling rotary kiln gate according to claim 1 is characterized in that described cooling water pipe is a metal hose.
