Abstract
The utility model discloses a high-temperature electrothermal kiln car type heating furnace. The high-temperature electrothermal kiln car type heating furnace comprises a hearth (7) and a kiln car (8) for placing and transporting heated products; a rear wall (10) of the hearth and sidewalls (9) of two sides of the hearth are bricked by firebricks; and electric heating elements (1, 2) are arranged on the sidewalls (9) of the hearth. The high-temperature electrothermal kiln car type heating furnace is characterized in that: the rear wall of the hearth and the inner side of the vertical wall of the kiln car (8) are also provided with the electric heating elements. When a kiln door is closed, a wiring guillotine of the electric heating element of the inner side of the vertical wall of the kiln car and a connecting clamp of the electric heating element of the hearth are connected, thereby realizing rapid connection; when the kiln door is closed, the wiring guillotine is communicated with the connecting clamp; after the guillotine is closed for electricity transmission, the electric heating element of the inner side of the vertical wall of the kiln car and the electric heating elements of the inner sidewall and the rear wall of the hearth generate heat simultaneously to improve the temperatures of the vicinity of the furnace door and the rear wall and achieve even temperature in the hearth, thereby improving the finished product rate of product firing, reducing the time of heat insulation and the thermal load time of the electric heating element, prolonging the service life of the electric heating elements and reducing cost for product production. .
Description
Technical field
The utility model belongs to hot industry products such as refractory material, pottery and fires usefulness and hot cell heating furnace, relate generally to a kind of high-temperature electric heat kiln car formula heating furnace (or claiming shuttle kiln, trolley type heating furnace), particularly the distribution and the quick-connect machanism of high-temperature electric heat kiln car formula heating furnace electrical heating elements (or claiming heating, heating element heater, heater).
Background technology
Up to now, be used for the electric heating kiln car formula heating furnaces that hot industry field product is fired and hot cell is used such as refractory material, pottery, electrical heating elements (or claiming heater) all is distributed in the both walls of burner hearth, and terminals stretch out furnace roof, connect power line above furnace roof; The inboard of wall does not have electrical heating elements behind fire door place kiln car and the stove.
Existing electric heating kiln car formula heating furnace is in running, (1) because electrical heating elements only is arranged in the burner hearth both sides, no heater in wall and the fire door behind the stove (being the kiln car wall), in the process that product is fired behind the stove near wall and the fire door temperature low, cause temperature distributing disproportionation in the burner hearth, do not reach technological requirement, cause the yield rate of product to reduce.(2) in order to make the temperature lower region approach the temperature of technological requirement, must prolong temperature retention time, thereby prolong the production cycle, increase energy resource consumption.(3) U type heater is distributed in the burner hearth both walls thick and fast, causes the excellent hole number of furnace roof lifting heater to increase, and furnace roof brick bearing capacity descends, and furnace roof easily caves in.Like this, because the intensive row's rod in both sides, not only cause the furnace temperature inequality, reduced yield rate, increased the firing time of product, improved cost, and furnace roof easily caved in, strengthened electrical heating elements the thermic load time, shorten its service life, increased the expense of the number of times of repair and replacement and kiln operation.
Summary of the invention
The purpose of this utility model provide a kind of can overcome near the fire door with stove after the high-temperature electric heat kiln car formula heating furnace (or claiming shuttle kiln, trolley type heating furnace) of shortcomings such as non-uniform temperature and life of arched roof be short on the low side, the burner hearth of wall place temperature.
The purpose of this utility model can realize by following technical scheme: it comprises burner hearth, is used to place the kiln car that transports heated product, the back wall of burner hearth and the side wall of burner hearth both sides are built into by refractory brick, on the side wall of burner hearth both sides electrical heating elements is set, on the back wall of burner hearth and the wall inboard of kiln car also be provided with electrical heating elements.
The electrical heating elements of kiln car wall inboard is that cold and hot end has certain angle and becomes L shaped U type molybdenum disilicide rod, its heating end places the refractory brick that is built into flute profile, cold junction passes the kiln car wall and exposes outside the kiln car wall, between the heating element heater by lead connect mutually the back be connected with an end of plug-in strip (or the fast bindiny mechanism of expressing one's gratification), the other end of plug-in strip extends to furnace roof top by lead and is connected with wall heater behind the stove; Side wall in the burner hearth and after within the walls electrical heating elements be the U type molybdenum disilicide rod of straight shape (cold and hot end angle is 180 °), all hang on the furnace roof brick, cold junction stretches out furnace roof.
Advantage of the present utility model: when kiln car is pushed in the stove, electrical heating elements is realized connecting fast by plug-in strip in the kiln car wall; After combined floodgate send electricity, electrical heating elements on the electrical heating elements of kiln car wall inboard and burner hearth inside wall, the back wall generates heat simultaneously, improved near the temperature that reaches wall place, back of wicket, the temperature that reaches in the burner hearth is even, thereby improved the yield rate that product is fired, reduced temperature retention time, reduced the thermic load time of electrical heating elements, prolonged the service life of electrical heating elements, reduced the density of burner hearth both sides heaters, improve its bearing capacity, prolonged the life-span of furnace roof, reduced production cost of products.
