Abstract

The utility model relates to a resistance type non-insulating hot-air stove which is an electric heat exchanger dispensed with heat insulation. The main purpose is to provide heat sources for various drying systems and other systems needing hot air. The utility model has two main characteristics. One is that a cold-air annular clearance (5) is arranged between an outer casing (1) and a heating chamber (8), and thus, the cold air entering in the stove can be preheated. Therefore, the utility model has no a heat insulation layer, small size, high heat efficiency and energy saving. The other characteristic is that resistance wire components (6) adopt the drawer type, and the resistance wire components can be conveniently pushed into and pulled out. Thus, users can optionally combine the resistance wire components according to required powers, which is very convenient for use and maintenance.

Description

Resistance type non-insulating hot-air stove

The utility model relates to a kind of electric heat-exchanger rig-resistance-type that need not to be incubated does not have the heat preservation hot wind furnace.Its main application is for various drying systems and needs other system of hot-air that thermal source is provided.

That generally uses at present use electric central warm air furnace, because its structure is very unreasonable, often needs huge heat-insulation layer, and is indivisible overall structure, make its volume greatly, big energy-consuming.Installation and transportation are all very inconvenient.

The purpose of this utility model provides a kind of resistance-type rational in infrastructure, that volume is little, energy-conservation does not have the heat preservation hot wind furnace.

The purpose of this utility model is achieved like this:

Between the shell of hot-blast stove and heating clamber, be provided with the cold wind annular space, make the cold air that enters in the hot-blast stove before heating, at first carry out preheating, enter the heating clamber heating then.In addition, the resistance wire assembly that is used for heating adopts drawer type, and each assembly is three-phase, can self balance, and can be according to the combination arbitrarily of power demand size.

Describe its structure and operation principle in detail below in conjunction with the embodiment accompanying drawing:

Fig. 1 does not have heat preservation hot wind furnace furnace binding schematic diagram for resistance-type.

Wherein: (a) be the front view of this body of heater;

(b) be the vertical view of this body of heater;

(c) be the side view of this body of heater.

Referring to Fig. 1, be provided with cold wind annular space 5 between hot-blast stove shell 1 and heating clamber 8, cold air inlet 2 is located at the end sides of body of heater, and the resistance wire assembly 6 of drawer type all is installed in heating clamber 8, hot-blast outlet 4 and is in same end with cold air inlet 2 on an end face of hot-blast stove.7 is the air distribution plate, the 9th, and the resistance wire assembly support, 10 is that deflector also plays reinforcement.

Cold air enters hot-blast stove from cold air inlet 2, carries out preheating by cold wind annular space 5, enters heating clamber 8 through air distribution plate 7,6 heating of resistance wire assembly are arranged after, enter hot blast chamber 3, discharge by hot-blast outlet 4 then.Cold air has been walked a circulation in hot-blast stove, discharge after preheating, heating, thereby finish its heating process, offers drying system or other system and uses.

Compared with prior art: it has two big characteristics: one, and the cold wind annular space 5 that adds between shell 1 and heating clamber 8 has two effects, and first is isolated from the outside heating clamber, to prevent scattering and disappearing of heat.Second can make the cold air preheating that enters in the stove, and this hot-blast stove need not heat-insulation layer thus.Because above-mentioned rational structure, this hot-blast stove volume is little, is convenient to transportation, simultaneously thermal efficiency height, energy-conservation.Its another characteristics are resistance wire assembly 6 employing drawer types that this hot-blast stove is used for adding hot-air, can outwards pull out easily, separate between the assembly, and each assembly all is a three-phase, can self balance, the user can or be come into operation respectively according to the power demand arbitrary combination, therefore, uses and keeps in repair all very convenient.

Embodiment: shell 1, heating clamber 8 etc. are welded by iron plate or corrosion resistant plate as mentioned above, and resistance wire assembly 6 is that resistance wire is fixed on the resistance wire assembly support 9 by certain way, thereby form drawer type, and then are installed on demand in the heating clamber 8.It is good through trial effect that the resistance-type of above-mentioned special construction does not have the heat preservation hot wind furnace.

Claims

A kind of hot-air feedway that utilizes resistance wire as heating element heater, particularly a kind of resistance-type does not have the heat preservation hot wind furnace, it is made up of hot-blast stove shell (1), heating clamber (8), resistance wire assembly (6), cold air inlet (2) and hot-blast outlet (4), it is characterized in that:

A) between hot-blast stove shell (1) and heating clamber (8), be provided with cold wind annular space (5);

B) the resistance wire assembly of installing in heating clamber (8) (6) is to adopt drawer type.
