The utility model content
The technical problem that the utility model solves provides a kind of each corner of oven door body that makes by the fire door of the electric arc furnaces of the timely cooling of water.
The utility model solves the technical scheme that its technical problem adopted: the fire door of electric arc furnaces, comprise oven door body, and said oven door body comprises roof; Left side wall and right side wall, said oven door body inside is separated to form two side cavity and the intermediate cavity between two side cavity through two midfeathers, and an end of said midfeather links to each other with oven door body; The other end forms free end; Said oven door body is provided with water inlet, and the said water inlet water inlet pipe inner with being arranged on oven door body links to each other, and said water inlet pipe comprises two water inlet pipe outlets; Said two water inlet pipes outlet lays respectively in two side cavity; Said oven door body is provided with delivery port, and the free end of said midfeather is connected with diaphragm plate, and the right ends of said diaphragm plate is extended towards the left side wall and the right side wall of oven door body respectively; The upper end of said diaphragm plate extends to the upper end of corresponding midfeather, and the lower end of said diaphragm plate extends to the lower end of corresponding midfeather; Said delivery port is arranged on the said roof and delivery port is communicated with intermediate cavity.
Further be: comprise two said water inlets, one of them water inlet is arranged on the left side wall, and another water inlet is arranged on the right side wall.
The beneficial effect of the utility model is: through diaphragm plate is set, make current can flow to each corner of two side cavity and intermediate cavity, also just make each corner of oven door body in time to be cooled off by water, thereby help prolonging the service life of fire door.
Description of drawings
Fig. 1 is the front view of fire door of the electric arc furnaces of the utility model;
Fig. 2 is the vertical view of fire door of the electric arc furnaces of the utility model.
Be labeled as among the figure: oven door body 1, diaphragm plate 2, midfeather 3, intermediate cavity 4, left side wall 5, right side wall 6, side cavity 7, side cavity 8, water inlet 9, delivery port 10, water inlet pipe 11, water inlet 12, water inlet pipe outlet 13, water inlet pipe outlet 14, roof 15.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
As depicted in figs. 1 and 2, the fire door of electric arc furnaces comprises oven door body 1; Said oven door body 1 comprises roof 15, left side wall 5 and right side wall 6, and said oven door body inside is separated to form side cavity 7 and side cavity 8 and the intermediate cavity between two side cavity 4 through two midfeathers 3; One end of said midfeather 3 links to each other with oven door body 1, and the other end forms free end, and said oven door body 1 is provided with water inlet; Said water inlet links to each other with the water inlet pipe 11 that is arranged on oven door body 1 inside; Said water inlet pipe 11 comprises water inlet pipe outlet 13 and water inlet pipe outlet 14, and said two water inlet pipes outlet lays respectively in side cavity 7 and the side cavity 8, and said oven door body 1 is provided with delivery port 10; The free end of said midfeather 3 is connected with diaphragm plate 2; The right ends of said diaphragm plate 2 is extended with right side wall 6 towards the left side wall 5 of oven door body respectively, and the upper end of said diaphragm plate 2 extends to the upper end of corresponding midfeather, and the lower end of said diaphragm plate 2 extends to the lower end of corresponding midfeather; Said delivery port 10 is arranged on the said roof 15 and delivery port 10 is communicated with intermediate cavity 4.During use, owing to be provided with diaphragm plate 2, after water gets into two side cavity by water inlet pipe outlet 13 and water inlet pipe outlet 14; 2 directions flow along midfeather 3 towards diaphragm plate, and after water flow to diaphragm plate 2 positions, the guide effect that can receive diaphragm plate 2 was to diffusion all around; So just can make each corner of current direction, owing to intermediate cavity 4 links to each other with delivery port 10, therefore; Water finally can flow to intermediate cavity 4; Finally flow out,, can make oven door body 1 obtain in time cooling uniformly through constantly in oven door body 1, injecting recirculated water from delivery port 10.
On the above-mentioned oven door body 11 water inlet can only be set; But for the ease of sending water system to link to each other with the recirculated water that is positioned at oven door body 1 outside the water inlet pipe 11 in the oven door body 1; Said oven door body 1 is provided with two water inlets; Be respectively water inlet 9 and water inlet 12, one of them water inlet 9 is arranged on the left side wall 5, and another water inlet 12 is arranged on the right side wall 6.So in use, which side no matter recirculated water send water system to be arranged on oven door body 1 all has a water inlet corresponding with it, thereby is convenient to send water system to link to each other water inlet pipe 11 and recirculated water.And, through two water inlets 9 are set, in use; But water inlet of shutoff uses a water inlet, also can use simultaneously by two water inlets; Send water just for simultaneously two water inlets, can strengthen the flowability of recirculated water like this, better to the cooling effect of oven door body 1.
