Abstract
The utility model discloses a far-infrared heating pipe and a heating and drying apparatus. The far-infrared heating pipe comprises outer armor produced by a seamless stainless steel pipe. A linear heating core is placed in the pipe along a central axis. A magnesium oxide power layer is filled and compacted in a gap between the heating core and the outer armor. The heating and drying apparatus comprises a heating body produced by bending and reeling a plurality of the heating pipes. The heating body is equipped with multiple connecting rods arranged in parallel and at intervals. The heating body is fixed on the inner wall of a drying oven through the connecting rods and is connected with the drying oven through a connecting flange. The far-infrared heating pipe and a heating and drying apparatus not only save power and electricity and have high thermal efficiency, but also have characteristics of uniform heating, wide application ranges, and long service lives.
Description
Technical field
The utility model relates to a kind of heating, drying equipment, relates in particular to a kind of far-infrared heating tube and heating, drying device.
Background technology
At present, known drying unit is also to utilize far-infrared heater, and what calandria used is to make infrared source with helical tungsten filament.Because tungsten filament is harder and crisp, its yield strength is low.The tungsten filament of helical spring body is after bending, and the resistance in the corner diminishes, and temperature is higher, and the little place of resistance is easy to blow after long-time energising heating, and durability is not long.With the U-shaped electric heating tube that tungsten filament is done, flexibility can not be done greatly, and the distance between heating tube can be very large so, more than the distance of general two adjacent straight tubes had 100mm, the distance between heating tube was too large, can cause heating uneven, whole baking oven is long heating time, and heating tube holds flimsy drawback.
The utility model content
The purpose of this utility model is to provide a kind of far-infrared heating tube, and it has the advantages that the heat efficiency is high, heating is even and applied widely, the problem that adopts helical tungsten filament to exist as infrared source to solve prior art mid and far infrared heater.
Another purpose of the present utility model is to provide a kind of Far-infrared Heating drying unit, and it has energy saving, the heat efficiency is high, heating is even and the characteristics of long service life, the problem that exists to solve prior art mid and far infrared heater.
For reaching this purpose, the utility model by the following technical solutions:
A kind of far-infrared heating tube, it comprises the outer armour of being made by gapless stainless steel tube, is placed with linear heating core along central axis cloth in pipe, between described heating core and outer armour, space filling and compacting have the magnesium oxide bisque.
Especially, described heating core adopts electric heating Nie Chrome alloy heating core, and it is shaped as columniform straight-bar.
Especially, the external diameter of described gapless stainless steel tube is 6mm.
A kind of Far-infrared Heating drying unit, it comprises the calandria that is formed by some heating tube bending and winding, be provided with the connecting rod that many parallel interval are arranged on described calandria, by connecting rod, calandria is fixed in the baking oven inwall, and described calandria is connected on baking oven by mounting flange, described heating tube comprises the outer armour of being made by seamless stainless steel, is placed with linear heating core along central axis cloth in pipe, and between described heating core and outer armour, space filling and compacting have the magnesium oxide bisque.
Especially, the width of described calandria is 876mm, adjacent heating tube apart from 18mm, totally 28.
Especially, described ring flange length is 77mm, and the tapping of ring flange external diameter corresponding to STH in oven cover, is put ring flange in the hole into, and is fixed in baking oven with CARBURIZING FURNACE FOR STAINLESS FASTENER outside baking oven.
The beneficial effects of the utility model are, compared with prior art the outer armour stainless steel of described far-infrared heating tube is very clean, and long-term use can not got rusty, and can reach 100,000 grades of lustration classes in the process of using; Use resistant to elevated temperatures magnesium oxide insulated material safety, reliability high, heating core and stainless steel casing can short circuits; Use the heating tube of this structure can curve as requested various shapes, light, and high life, thermal conversion rate is high, energy saving simultaneously.
Description of drawings
Fig. 1 is the profile of the far-infrared heating tube that provides of the utility model embodiment 1;
Fig. 2 is the structural representation of the Far-infrared Heating drying unit that provides of the utility model embodiment 1.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
see also illustrated in figures 1 and 2, in the present embodiment, a kind of far-infrared heating tube comprises the outer armour 1 of being made by gapless stainless steel tube, what in the pipe of edge, central axis laid is linear electric heating Nie Chrome alloy heating core 2, heating core 2 is straight-bars of column type, between heating core 2 and outer armour 1, the space is good with insulating properties, heat conductivility is good magnesia powder 3 also, be compacted into an integral body in the gap, magnesia powder 3 after compacting can not be scattered, magnesia powder 3 is just as being bonded together by glue, certain pliability is arranged, can be bent, stretch and can not rupture, disperse, the electric heating element of this metal armouring can add hot-air, metal die and various liquid.This structure is not only advanced, and the heat efficiency is high, and heating evenly.
When linear Nie Chrome alloy heating core 2 had electric current to pass through, the heat of generation, then was delivered in heated object or air and goes to metal tube surface diffusion by crystal magnesium oxide powder 3, reaches the purpose of heating.
A kind of Far-infrared Heating drying unit comprises the calandria 4 that is formed by 28 above-mentioned heating tube bending and winding, the width of described calandria 4 is 876mm, adjacent heating tube apart from 18mm, intensive like this arranging is in order to satisfy homogeneous heating, can guarantee that the heat-seal coating adhesive force on aluminium foil is even, fastness reaches the degree of GB.Be provided with the connecting rod 5 that 5 parallel interval are arranged on described calandria 4, by connecting rod 5, calandria 4 is fixed in the baking oven inwall, and described calandria 4 is connected on baking oven by mounting flange 6, described ring flange 6 length are made 77mm, M24 is made in the flange outer diameter tapping, with the hole that hole digger diameter 25 is opened diameter 25 in the oven cover inboard, flange is put in the hole, be fixed in baking oven with CARBURIZING FURNACE FOR STAINLESS FASTENER in the baking oven outside.
