Abstract
The utility model relates to an electric heater used for heating liquid. The utility model solves the defects of easy breaking and charged liquid caused by the breaking existing in prior art. The electric heater comprises a housing, an electric stove wire, a bracket and a connecting lead, and the bracket is provided with a thread groove. The electric stove wire is helically arranged in the thread groove, and the inner of the bracket is provided with a through hole. An earth line connecting rod is arranged in the through hole and is connected with an earth line connecting end. The utility model has the advantages of convenient operation, high safety and long working life.
Description
The utility model relates to electric heating appliance, particularly the electric heater that is used for heating liquid that is made of housing, electric furnace heating wire etc. in plating, chemical industry.
Present electric heater generally is made of housing, electric furnace heating wire, support, connection lead etc., electroplate, when liquid being heated in the chemical industry, because housing is an insulating sleeve, generally be to make by quartz glass sleeve or 95 glass bushings, and these sleeve pipes all are easy to fragmentation, use the heater of said structure, and are in a single day broken when heating liquid, to cause liquid charged, jeopardize personal safety.The leading-out terminal of the electric heater of present various structures is unsealed Open architecture in addition, because under the situation of sealing, air in the insulating sleeve at high temperature expands and can produce very big pressure, easily causes the insulating sleeve explosion at high temperature of materials such as quartz, glass.Though Open architecture can guarantee the air free flow in the insulating sleeve, but owing to be heated the boiling fluctuation that liquid produces under high-temperature condition, make liquid enter the insulating sleeve from lead end easily, cause the electric furnace heating wire short circuit in the electric heater, make the electric heater can't operate as normal, Gu this, the electric heater of this class formation is shorter useful life, use inconvenience, and dangerous
The purpose of this utility model is to overcome the deficiency in the above-mentioned prior art, and a kind of electric heater of safe in utilization, convenient, long working life is provided.
For achieving the above object, the utility model electric heater, comprise housing, electric furnace heating wire, support, connection lead, on described support, be provided with thread groove, described electric furnace heating wire helically coiling is in thread groove, be provided with through hole in support, wherein be provided with the ground wire cylinder lever connecting rod, described ground wire cylinder lever connecting rod links to each other with the ground wire union end.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing one of them embodiment of the utility model is described in further detail:
As shown in FIG., the utility model electric heater comprises the housing (1) of insulating case tubulose, can be made by materials such as glass or quartz, and support (4) also corresponds to cylindric, on support (4), be provided with thread groove (2), in the thread groove (2) of described electric furnace heating wire (3) spiral on the support (4).Be provided with two through holes (8) in support (4), each through hole is equipped with metal pull bar in (8), and one of them is ground wire cylinder lever connecting rod (5), in addition-individual for conducting electricity pull bar (6), it is a long section that two pull bars connect some joint supports (4).Ground wire cylinder lever connecting rod (5) in one of them through hole (8) links to each other with the ground wire union end through connecting lead (11), forms electric heater ground connection.Just in case housing breaks, heated liquid enters in the housing, not only can touch electric furnace heating wire, also can touch the ground wire cylinder lever connecting rod, make power supply form short circuit, and it is charged to be unlikely to whole liquid, thereby has avoided the electric shock of human body effectively.One of electric furnace heating wire (3) terminates on the conduction pull bar (6), passes support (4) again, links to each other with power end through connecting lead (11), and the other end directly links to each other with power end through connecting lead (11).In the sealer (9) of housing (1) port a sleeve pipe (10) is arranged, described connection lead (11) is arranged in the sleeve pipe (10).Be provided with spacer (7) at described support (4) two ends, described spacer (7) is supported on the inwall of housing (1), makes the bracket-suspending of thread groove shape in the housing (1) of tubulose, and the available mica sheet of spacer (7) is made.When the heating wire heating power, gas in the housing expands, because two power supplys connect leads and one Di are connected lead and are round shape line, in sleeve pipe, pass, three connect lead and just form air flue in sleeve pipes, gas in the housing can be freed in and out by air flue, keep air pressure and extraneous balance in the housing, make housing can not burst.
The utility model has following advantage than prior art:
1, owing to be provided with the ground wire cylinder lever connecting rod in the housing, in case housing is in use broken, the ground wire cylinder lever connecting rod is instant By heated conducting liquid and electric power generating composition loop, thereby guarantee safety;
2, adopt support to be provided with thread groove and the support two ends are provided with the spacer structure, make to have the space that electric furnace heating wire enough is installed reliably in the housing, can adopt enough thick electric furnace heating wire, guarantee that again electric furnace heating wire does not produce the creep short circuit, the electric furnace heating wire support is firm not damaged, long working life;
3, a sleeve pipe is arranged in the sealer of housing port, connect lead and be arranged in the sleeve pipe, make liquid that can not infiltrate, easy to use;
4, the air in the housing can not produce high pressure during high temperature by the discharging of the backlash freedom between the sleeve pipe connecting lead wire, causes the insulation shell explosion.
Claims (3)
1. electric heater, comprise housing (1), electric furnace heating wire (3), support (4), connect lead (11), it is characterized in that on described support (4), being provided with thread groove (2), described electric furnace heating wire (3) helically coiling is in thread groove (2), in support (4), be provided with through hole (8), wherein be provided with ground wire cylinder lever connecting rod (5), described ground wire cylinder lever connecting rod (5) links to each other with the ground wire union end.
2. electric heater according to claim 1 is characterized in that in the sealer (9) of housing (1) port a sleeve pipe (10) being arranged, and described connection lead (11) is arranged in the sleeve pipe (10).
3. electric heater according to claim 2 is characterized in that being provided with spacer (7) at described support (4) two ends, and described spacer (7) is supported on the inwall of housing (1).
