Description

A kind of stone or metal plate for standing a stove on as a precaution against fire thermal cut protective device of far infrared electric furnace

One technical field

The utility model relates to a kind of stone or metal plate for standing a stove on as a precaution against fire thermal cut protective device of far infrared electric furnace.

Two background technologies

Existing infrared ray electric furnace; Its structure is as shown in Figure 1, comprises base 1, loam cake 2, stone or metal plate for standing a stove on as a precaution against fire 3, control module 5 and the crystallite plate 4 of heating wire is housed, as you know; The tradition stone or metal plate for standing a stove on as a precaution against fire need as far as possible up be radiated crystallite plate 4 with heat; Therefore the scope of temperature up to 400 degrees centigrade to 600 degrees centigrade of crystallite plate 4, but make the bottom of stone or metal plate for standing a stove on as a precaution against fire 3 and the side periphery temperature can not be too high again, otherwise softening perhaps control module 5 cisco unity malfunctions of base 1 hot melt.

When short circuit, the moment of heating wire has big electric current to pass through, and the temperature controller that is installed in stone or metal plate for standing a stove on as a precaution against fire central authorities does not also have enough time to react; Heating wire has passed through thermal cut, causes whole electric furnace to be scrapped, in view of this; Generally thermal cut-off is installed at bottom or side at stone or metal plate for standing a stove on as a precaution against fire; But this mode temperature-sensitive is insensitive inaccurate, because there is not directly to detect the temperature of heating wire, these stove and accessorys do not meet security regulations.

Three summary of the invention

The purpose of the utility model is to provide a kind of stone or metal plate for standing a stove on as a precaution against fire thermal cut protective device of far infrared electric furnace, can accurately detect the temperature of heating wire, is quick on the draw, and proper is effectively protected heating wire.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of stone or metal plate for standing a stove on as a precaution against fire thermal cut protective device of far infrared electric furnace; Comprise stone or metal plate for standing a stove on as a precaution against fire, heating wire, first binding post, second binding post and electric wire; Heating wire is installed on the stone or metal plate for standing a stove on as a precaution against fire, and the two ends of heating wire connect first binding post and second binding post respectively, and it also comprises thermal cut-off in addition; One end of thermal cut-off is connected on first binding post or second binding post, and the other end of thermal cut-off is connected with electric wire.

Technique scheme can also be done further to improve through following technical measures.

Described first binding post, second binding post are installed on the terminal socket, and described terminal socket is installed on the stone or metal plate for standing a stove on as a precaution against fire.

Said stone or metal plate for standing a stove on as a precaution against fire comprises disk body, insulating collar and lower steel ring, and heating wire is installed in the end face of disk body, and insulating collar is positioned at the peripheral of heating wire and is supported on the disk body, and the disk body edge is provided with breach, and terminal socket is nested on the breach, and the terminal socket end face is compressed by insulating collar.

Said disk body central authorities are equipped with K type thermocouple.

Described thermal cut-off one end can be connected with first binding post or second binding post through a thermal conductive metal plate.

The advantage of the utility model is: an end of (1) thermal cut-off is connected on first binding post or second binding post; The other end of thermal cut-off is connected with electric wire, and thermal cut-off directly detects the temperature of heating wire through binding post, is quick on the draw; Proper is effectively protected heating wire; (2) described first binding post, second binding post are installed on the terminal socket, and described terminal socket is installed on the stone or metal plate for standing a stove on as a precaution against fire, and stone or metal plate for standing a stove on as a precaution against fire comprises disk body, insulating collar and lower steel ring; Heating wire is installed in the end face of disk body, and insulating collar is positioned at the peripheral of heating wire and is supported on the disk body, and the disk body edge is provided with breach; Terminal socket is nested on the breach; The terminal socket end face is compressed by insulating collar, and is simple in structure, easy for installation; (3) disk body central authorities are equipped with K type thermocouple, and reaction is accurately quick more, and protective value is better.

Five specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Extremely shown in Figure 4 like Fig. 2; A kind of stone or metal plate for standing a stove on as a precaution against fire thermal cut protective device of far infrared electric furnace comprises stone or metal plate for standing a stove on as a precaution against fire 1, heating wire 2, first binding post 3, second binding post 4 and electric wire 5, and heating wire 2 is installed on the stone or metal plate for standing a stove on as a precaution against fire 1; The two ends of heating wire 2 connect first binding post 3 and second binding post 4 respectively; It also comprises thermal cut-off 6 in addition, and an end of thermal cut-off 6 is connected on first binding post 3 or second binding post 4, and the other end of thermal cut-off 6 is connected with electric wire 5; Described first binding post 3, second binding post 4 are installed on the terminal socket 7, and described terminal socket 7 is installed on the stone or metal plate for standing a stove on as a precaution against fire 1.Said stone or metal plate for standing a stove on as a precaution against fire 1 comprises disk body 11, insulating collar 12 and lower steel ring 13; Heating wire 2 is installed in the end face of disk body 11; Insulating collar 12 is positioned at the peripheral of heating wire 2 and is supported on the disk body 11, and disk body 11 edges are provided with breach 111, and terminal socket 7 is nested on the breach 111; Terminal socket 7 end faces are compressed by insulating collar 12, and said dish 111 central authorities are equipped with K type thermocouple 8.Thermal cut-off 6 one ends can be connected with first binding post 3 or second binding post 4 through a thermal conductive metal plate.
