Abstract

A nested warm air furnace belongs to the technical field of building construction, and is characterized in that a combustion furnace is mounted in the center of a heat source furnace, a spirally ascending smoke discharge duct is communicated with the top of the combustion furnace and communicated with the outside of the heat source furnace, a delivery pipe belt is communicated with the top of the heat source furnace, and the bottom of the delivery pipe belt is provided with an air supply port communicated with a fan. The nested warm air furnace has the advantages that the warming problem of concrete construction in winter under special environmental conditions is solved effectively, and further the nested warm air furnace saves energy resources, is low in cost, convenient in operation, short in manufacturing cycle and small in construction interference, and the like.

Description

The nested type hot-blast stove

Technical field

The utility model belongs to technical field of building construction, relates to a kind of improvement of concreting in cold weather maintenance.

Background technology

In present concrete winter construction tissue, concrete maintenance heats up and generally adopts boiler band radiator (pipe) or with the method for some allusion quotations tungsten lamp.Boiler band radiator (pipe) heating is to utilize Boiler Steam intensification place processing of heating to needs, this heating scheme need be selected suitable boiler model according to the concreting in cold weather plan, requires to calculate radiator (pipe) according to job site site condition and concrete curing surface temperature simultaneously and the group number is set and distance is set.This method heat supply is even, heat is sufficient, and energy waste is big, construction cost is high, be subjected to drawbacks such as the place restriction is big, construction is disturbed greatly, the construction period is long but exist.Allusion quotation tungsten lamp method is the intensification place processing of heating to needs of the heat that utilizes some allusion quotations tungsten lamp to work simultaneously to produce.Shortcomings such as this method is easy to operate, is subjected to the place restriction less, but exists energy waste bigger, and uneven heating is even.

Summary of the invention

The purpose of this utility model is: a kind of nested type hot-blast stove is provided, and it is can heat supply even, heat is sufficient, easy to operate, is subjected to the less concrete maintenance of realization of place restriction.

The technical solution of the utility model is: the center is equipped with combustion furnace in heat source furnace, the combustion furnace top is communicated with spiral rising smoke discharging pipe, outside the smoke discharging pipe pass-out heat source furnace, be communicated with the conveying pipe racks, carrying the pipe racks bottom to have air outlet to be communicated with blower fan at the heat source furnace top.

The beneficial effects of the utility model are: not only effectively solved under the special environment condition, the heating problem of concreting in cold weather has also simultaneously that energy savings, with low cost, easy to operate, fabrication cycle are short, advantages such as little are disturbed in construction.

Description of drawings

Fig. 1 is the utility model structure cutaway view.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in the figure, the 1st, heat source furnace, the 2nd, combustion furnace, the 3rd, fire grate, the 4th, blower fan, the 5th, base, the 6th, smoke discharging pipe, the 7th, control valve door, the 8th is carried pipe racks.

The nested type hot-blast stove is the burning that utilizes combustion furnace 2, and with the atmosphere temperature rising between heat source furnace 1 and the combustion furnace 2, high temperature air distributes after carrying pipe racks 8 to be sent to the place that needs intensification, relies on the circulation of air heat-shift to reach the purpose that environment is heated up.The transmitting power of nested type hot-blast stove derives from blower fan 4, and the main effect of blower fan 4 is that outside air is sucked in the heat source furnace 1, simultaneously with in heat source furnace 1 furnace chamber hot-air be blown into and carry pipe racks 8.According to requirement of engineering, at heat source furnace 1 top a plurality of outlets can be set, hot-air can be carried hot-air along the conveying pipe racks 8 of appointment.

Combustion furnace 2 by heat conduction faster sheet metal be welded into, fire grate 3 is divided into two combustion furnace, the lower body furnace chamber is used to deposit ashes, the upper body furnace chamber is used for combustion material (timber, coal etc.);

Heat source furnace 1 is welded into by two blocks of sheet metals, and the resistant to elevated temperatures thermal insulation material of middle filling is used to store high-temperature gas in the heat source furnace 1 outside the combustion furnace 2;

Smoke discharging pipe 6 not influencing under the preceding topic of smoke evacuation, increases duct length by common thin-walled steel pipe manufacturing as far as possible, to utilize the heat in the cigarette to greatest extent;

Select blower fan 4 with its coupling for use according to the size of nested type hot-blast stove heat capacity, preferentially select frequency conversion fan for use.

Carry pipe racks 8 and heat source furnace 1 junction that control valve door 7 is installed, control valve door 7 control pipe racks 7 are supplied gas.

Claims

1. nested type hot-blast stove, it is characterized in that: the center is equipped with combustion furnace in heat source furnace, and the combustion furnace top is communicated with spiral rising smoke discharging pipe, outside the smoke discharging pipe pass-out heat source furnace, be communicated with the conveying pipe racks at the heat source furnace top, carrying the pipe racks bottom to have air outlet to be communicated with blower fan.
