Abstract
The utility model relates to an electric heating jacket for effectively avoiding liquid corrosion, which is used for directly heating vessels such as balloon flasks in various chemical experiments. The electric heating jacket mainly comprises a shell, a thermal insulation layer and a cast aluminium heating jacket, wherein an electric heating tube is arranged in the cast aluminium heating jacket, the cast aluminium heating jacket is cast into a concave internal spherical heating jacket, the electric heating tube is arranged on the inner wall of the heating jacket, and uniformly distributed heat conduction holes are formed in the concave internal spherical surface of the cast aluminium heating jacket; the outer wall of the heating jacket is coated with the thermal insulation layer so as to form a heating jacket entirety together with the shell; and a bottom partition plate is arranged in the shell, uniformly distributed shell radiating windows are arranger above the side face of the shell, and a power switch, a voltmeter and a voltage adjusting knob are arranged below the side face of the shell. According to the electric heating jacket, the cast aluminium heating jacket is rapid in heat conduction and uniform in heat distribution, so that the electric heating jacket can effectively prevent overflowing liquid from corroding the heating jacket.
Description
Technical field
The utility model relates to a kind of electric heating cover of effectively avoiding liquid corrosion, in all kinds of chemical experiments, for the direct-fired electric jacket of the vessel such as balloon flask, can effectively avoid overflow to cause corrosion and the damage of heating jacket heating wire.
Background technology
Directly heating is very convenient and practical to vessel such as all kinds of balloon flasks in chemical experiment, to use electric heating cover, but the as easy as rolling off a log electrical heating wire that enters into asbestos fibre parcel of the overflow in use procedure causes corrosion wire breakage or causes the faults such as heating jacket electric leakage.Designing a kind of electric heating cover of effectively avoiding liquid corrosion meets in all kinds of chemical experiments very necessary to the direct heating of the vessel such as class balloon flask.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of electric heating cover of effectively avoiding liquid corrosion that in chemical experiment, the direct heating to vessel such as class balloon flasks is used is provided, meets effectively avoiding the corrosion of overflowing liquid to heating jacket in the direct heating process of spherical vessel.
The technical solution of the utility model is:
A kind of electric heating cover of effectively avoiding liquid corrosion of the utility model, mainly formed by shell, heat-insulation layer and cast aluminium heating jacket, electric heating tube is equipped with in described cast aluminium heating jacket inside, cast aluminium heating jacket is cast as spill Internal Spherical Surface heating jacket, electric heating tube is arranged on heating jacket inwall, and electric heating tube is connected with power unit by binding post; Cast aluminium heating jacket spill Internal Spherical Surface is provided with equally distributed thermal hole; Described heat-insulation layer is wrapped in heating jacket outer wall and shell forms a heating jacket entirety; Enclosure is provided with a bottom division board, and there is equally distributed shell radiator window top, shell side, and below, shell side is provided with power switch, voltmeter and voltage-regulation knob.
The needs that use according to reality, cast aluminium heating jacket can be cast as the spill Internal Spherical Surface of different volumes, to meet the spherical vessel heating needs of different volumes.
Advantage of the present utility model:
1, the cast aluminium heating jacket heat conduction that the utility model uses is fast, and heat distribution is even, can be to the fine heating of spherical vessel; 2, in heating or use procedure after overflow on cast aluminium heating jacket or above the division board of bottom, easily cleaning in time, difficult corrosion, not fragile heating jacket; 3, the inner electric heating tube that adopts of cast aluminium heating jacket, the mode of heating of the heating wire of having avoided traditional heating cover under asbestos fibre parcel, has superior insulating properties, guarantees that safety coefficient is high; 4, cast aluminium heating jacket has a large amount of equally distributed thermal holes, can form thermal convection current effect, realizes heated object and is heated evenly, and guarantees not occur bursting of category of glass ball heater ware; 5, cast aluminium heating jacket is except can, to heating various metal ball shaped vessel glass, pottery heating, being difficult for occurring leaky; 6, according to actual needs, cast aluminium heating jacket spill sphere can be made into the spherical vessel heating needs that meet different volumes.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of electric heating cover of effectively avoiding liquid corrosion of the utility model.
1. shells in figure, 2. power switch, 3. heat-insulation layer, 4. cast aluminium heating jacket, 5. shell radiator window, 6. thermal hole, 7. electric heating tube, 8. voltmeter, 9. bottom division board, 10. voltage-regulation knob.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is conducted further description:
In Fig. 1, a kind of electric heating cover of effectively avoiding liquid corrosion of the utility model, is mainly made up of shell 1, heat-insulation layer 3 and cast aluminium heating jacket 4, and electric heating tube 7 is equipped with in described cast aluminium heating jacket 4 inside, and cast aluminium heating jacket 4 is cast as spill Internal Spherical Surface heating jacket; Electric heating tube 7 is arranged on heating jacket inwall, and electric heating tube 7 is connected with power unit by binding post; Cast aluminium heating jacket 4 spill Internal Spherical Surface are provided with equally distributed thermal hole 6; Described heat-insulation layer 3 is wrapped in heating jacket outer wall and shell 1 forms a heating jacket entirety; Shell 1 inside is provided with a bottom division board 9, and there is equally distributed shell radiator window 5 shell 1 top, side, and shell 1 below, side is provided with power switch 2, voltmeter 8 and voltage-regulation knob 10.
The needs that use according to reality, cast aluminium heating jacket 4 can be cast as the spill Internal Spherical Surface of different volumes, to meet the spherical vessel heating needs of different volumes.
When using, passes through the utility model after wire connecting power, power-on switch 2, and regulation voltage adjusting knob 10, by the suitable heating voltage of inner voltage regulator circuit control, controls cast aluminium heating jacket 4.Heat putting into spill Internal Spherical Surface after the corresponding heating liquid of spherical heated vessel splendid attire.In heating process, because spill Internal Spherical Surface has and lower thermal hole 6 that can convection current, can guarantee the effectively evenly heat distribution of cast aluminium heating jacket 4 to heated vessel, guarantee to be heated evenly.In experimentation, as there is overflow, its overflowing liquid can only touch cast aluminium heater block or enter into division board 9 tops, bottom, cleaning in time, can there is not the damage of liquid to heater block and power control component, can effectively avoid liquid corrosion electric heating cover, improve the service life of heating jacket.
