Description
Technical field
The utility model relates to a kind of single-ended thick electrothermal tube.
Background technology
Single-ended thick electrothermal tube comprises body, magnesia tube, sealant, rebasing and contact rod.
Single-ended thick electrothermal tube is compared and traditional single-end electric-heating tube, and body sectional area is larger, and internal diameter exceedes 30mm, and because body sectional area ratio is larger, solid not loose in order to ensure to press after the magnesium hydroxide filler draw of end, after upper fluid sealant, firmly, in pipe, filler is difficult for the moisture absorption.Ensure that contact rod reaches the standard of pull test simultaneously, conventionally adopt a columniform magnesia tube baking as fixing and raising density, after draw compression, reach above requirement.
Equally, because mouth of pipe end packing density is large, semi-finished product are in the time of drying, discharging damp, and in pipe, moisture is very difficult to eject; In the time of the draw, in pipe, moisture is still difficult to discharge, and has affected product quality, shortens the useful life of product.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of single-ended thick electrothermal tube, make single-ended thick electrothermal tube in the course of processing when drying, discharging damp, in electrothermal tube pipe, moisture is discharged, and has improved the quality of single-ended thick electrothermal tube, has increased the useful life of single-ended thick electrothermal tube.
For solving above technical problem, the technical scheme that the utility model provides is:
A kind of single-ended thick electrothermal tube, comprise electrothermal tube body, magnesia tube, rebasing and contact rod, described electrothermal tube body is hollow cylindrical structural, two ends are all not closed, described electrothermal tube internal diameter of tube body is D1, described magnesia tube is hollow cylindrical structural, magnesia tube one end is closing structure, the other end is hatch frame, the closed end face of described magnesia tube is provided with two contact rod holes, described magnesia tube tube wall is provided with 1-2 strip through-hole, described strip through-hole is along magnesia tube tube wall horizontally set, and radially cave inward, the cross sectional shape of described strip through-hole is circular arc, described magnesia tube external diameter is D2, electrothermal tube internal diameter of tube body D1> magnesia tube outer diameter D 2, described electrothermal tube body fit is fixed on described magnesia tube outside, the closed end face of magnesia tube flushes with electrothermal tube body one end, described magnesia tube inside is filled with magnesia powder, described contact rod is fixed on described magnesia tube inside through described contact rod hole, on the described rebasing open end that is fixed on described magnesium oxide body, and with electric heating body interference fit.
The single-ended thick electrothermal tube of above-mentioned one, wherein, described electrothermal tube internal diameter of tube body D1 > 30mm.
The technical scheme the utility model proposes existing technology of comparing has following beneficial effect:
What the utility model proposes is provided with two strip through-holes at magnesia tube tube wall, in magnesium oxide body, fill after magnesia powder, magnesia powder can be filled in the gap forming between strip through-hole and electric heating tube body, when oven dry, in pipe, moisture is discharged by the gap of the granular magnesia powder of filling in strip through-hole, can ensure to insert the density of magnesia powder wherein, also can meet the pulling force standard-required of contact rod, reduce baking time, cost-saving, improve the quality of products, extend the useful life of product.
