Abstract
The utility model discloses a ceramic air-cooling electric heater, comprising a columnar shell and an insulating layer, wherein the insulating layer is tightly attached on the inner wall of the shell; the round shell is provided with an air opening; the outer wall of the shell is provided with a wire joint; the insulating layer is internally provided with an air duct which is communicated with the air opening; two sides of the air duct in the insulating layer are provided with ceramic base bodies; the inner wall of the ceramic base body is provided with a ceramic air groove; and the ceramic base body at the bottom ring of the ceramic air groove is internally wound with an electrical heating wire which penetrates through the shell and is connected with the wire joint. The ceramic air-cooling electric heater has fast heating and temperature rising and fast cooling.
Description
Technical field
The utility model belongs to the heater field, specifically, is a kind of outer air-cooled electric heater of plastics machinery barrel that is used for.
Background technology
In industries such as chemical industry, injection mouldings, raw material heat fused in the plastics machinery barrel mainly is to rely on electric heater to finish, and present electric heater adopts cast aluminium or cast steel electric heater to realize more, the shortcoming of this electric heater is: heating is slow, cooling is slow, and therefore can not adapt to present heating dissolves fast, the fast cooling requirement of needed heating; A kind of electric heater is also arranged by water-cooled or air-cooled the cooling on the market now, adopt cast aluminium or cast steel to make but this kind electric heater is also more, the existence heating is slow, cooling is slow, the relatively poor defective of effect of heat insulation.
The utility model content
Technical problem to be solved in the utility model is to provide fast, the fast cooling pottery of a kind of heat temperature raising air-cooled electric heater.
The technical solution of the utility model is as follows: design the air-cooled electric heater of a kind of pottery, comprise cylindrical shell and heat-insulation layer, described heat-insulation layer is adjacent to wall in the enclosure, on this shell, be provided with the air port, be provided with power lug at described outer shell outer wall, its main points are: be provided with the air channel in described heat-insulation layer, this air channel communicates with described air port, ceramic matrix is equipped with in both sides, air channel in described heat-insulation layer, this ceramic matrix inwall is provided with ceramic wind groove, be wound with electrical heating wire in the ceramic matrix of described ceramic wind bottom land circle, described electrical heating wire passes at described shell and is connected with power lug.When the utility model during in the course of work, energising makes the electrical heating wire heating, this moment is owing to the existence of heat-insulation layer and pottery, high insulating effect, quick heating, therefore material dissolves comparatively fast, when needs cool off, because the external air blast in air port etc. are opened air blast, wind to two side flow, reaches the purpose of quick cooling by ceramic wind groove.
Described shell rolls into cylindric by a corrosion resistant plate, commissure is connected by screw rod, two ends are all to in-flanges and heat-insulation layer and ceramic matrix port fastening about this shell, this kind way has changed the conventional heater circular housing and has formed sealing effectiveness defect of bad, flange snapping convenient disassembly by the two halves merging.
Described ceramic wind fluted shaft moves along axial ceramic wind concentrated flow when entering the air channel to being distributed on described ceramic matrix inwall, so can making to release, and cooling effect is better.
Described air port is positioned at side wall of outer shell middle part, cooling rate basically identical everywhere like this, and good cooling results, described air port entrance point is lower than described ceramic wind groove groove top, so can make distinguished and admirablely to flow in ceramic wind groove substantially, reaches better cooling effect.
Described electrical heating wire helically coiling is in ceramic matrix, and this kind coiling mode is because electrical heating wire and ceramic matrix contact area are big, so heats is better.
Described ceramic matrix is the ceramic bar annular be combined into of " protruding " font by a plurality of cross sections, so can make the ceramic air-cooled electric heater that varies in size as required, avoid adopting different ceramic matrixs, saved cost according to dissimilar ceramic air-cooled electric heaters.
Beneficial effect: the utility model is simple in structure, owing to adopt ceramic material, and adopt the helically coiling electrical heating wire, so quick heating; Adopt axial ceramic wind groove, avoided the defective of traditional annular wind groove, therefore cooling is fast.
