Abstract
The utility model relates to a furnace of preventing overflowed liquid from an electric leakage. The furnace includes a bracket (1) and a heating element; the heating element is fixed on the bracket (1); the upper surface of the heating element is covered with a metal protection mesh (2); the heating element is formed by a square fire-proof ceramic disc (3) and more than three quartz resistance heating pipes (4); and a heating part and electrodes at two ends of each quartz resistance heating pipe (4) are bended to form an inverted "U" shape. When the furnace of preventing the overflowed liquid from the electric leakage is used, the electric shock does not happen and the heating wire is not damaged even if the chemical solution overflows from the vessel and flows into the surface of the metal protection mesh, so that the high safety and the long service life of the furnace are realized.
Description
Technical field
The utility model relates to a kind of electric furnace, particularly a kind of electric furnace of anti-overflow fluid electric leakage.
Background technology
Existing electric furnace comprises heating wire, for the fixing support of heating wire, wherein spiral heating wire is fixed in some cannelures of support upper side, heating wire exposes.When chemical industry is used heating, the container of splendid attire chemical solution is placed on electric furnace, once the chemical solution in container outwards overflows, chemical solution containing conducting electrolyte flows directly into the heating wire surface on support, may cause electric short circuit, or cause burning of heating wire, shorten the useful life of electric furnace.Sometimes the danger that even causes operating personnel to get an electric shock.
The utility model content
The purpose of this utility model is the problem that fail safe is low, the life-span is short existed in existing electric furnace in order to solve, and the electric furnace that provides a kind of anti-overflow fluid safe, that the life-span is long to leak electricity.
The purpose of this utility model is achieved in that a kind of electric furnace of anti-overflow fluid electric leakage, comprises support and heater element, and heater element is fixed on the top of support; It is characterized in that: the heater element upper surface is stamped a metal protecting wire net; Described heater element by square refractory dish and more than three quartzy resistance heating pipe formed; Described square refractory dish upper surface has elongated slot parallel more than three, and two cecum places of every elongated slot all establish the through hole that runs through the refractory dish; A quartzy resistance heating pipe is installed in every elongated slot; Heating part and the two end electrodes of quartzy resistance heating pipe partly are bent into down " U " shape, and heating part inlay card wherein is in elongated slot, and partly through these elongated slot two cecums, corresponding through hole to refractory dish below connects power supply lead wire to two end electrodes.
Compared with the prior art, the beneficial effects of the utility model are: owing to having adopted technical scheme described in the utility model, during use, even chemical solution is excessive and flow into metal protecting wire net surface from container, its chemical solution moisture can be evaporated rapidly by the metal protecting wire net of high temperature, and, after in the chemical solution that has little time to stop inflow support, have again the outer quartz ampoule of resistance wire to stop isolation.So can not cause the danger of electric shock, can not damage heating wire, so the life-span safe, electric furnace is long yet.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the three-dimensional view of an embodiment of the present utility model.
Fig. 2 is the internal structure A-A generalized section of Fig. 1 embodiment.
In figure: 1 support; 2 metal protecting wire nets; 3 refractory dishes; 4 quartzy resistance heating pipes; 5 elongated slots; 6 power supply lead wires.
Embodiment
See Fig. 1 and Fig. 2, a kind of electric furnace of anti-overflow fluid electric leakage, comprise support 1 and heater element, and heater element is fixed on the top of support 1; The heater element upper surface is stamped a metal protecting wire net 2; Described heater element by square refractory dish 3 and more than three quartzy resistance heating pipe 4 formed; Described square refractory dish 3 upper surfaces have elongated slot parallel more than three 5, and two cecum places of every elongated slot all establish the through hole that runs through refractory dish 3; A quartzy resistance heating pipe 4 is installed in every elongated slot; Heating part and the two end electrodes of quartzy resistance heating pipe 4 partly are bent into down " U " shape, and heating part inlay card wherein is in elongated slot 5, and partly through these elongated slot two cecums, corresponding through hole to refractory dish 3 belows connect power supply lead wire 6 to two end electrodes.
Present embodiment is for the container of splendid attire chemical solution, when quartzy resistance heating pipe 4 heating power, the metal protecting wire net 2 covered at the heater element upper surface is heated to aglow, when chemical solution is excessive from container, at first excessive being lost on aglow metal protecting wire net 2 of chemical solution evaporated rapidly, play the effect that has at first stopped chemical solution, when more chemical solution excessive through after metal protecting wire net 2 enters refractory dish 3, the quartz ampoule that quartzy resistance heating pipe 4 is outer by resistance wire, finally stop the direct contact resistance silk of chemical solution.
Claims (1)
