Abstract
The utility model discloses a two-door furnace door which comprises a large furnace door (1), wherein a tubular handle (2) is fixedly connected onto one openable side of the large furnace door (1), a small furnace door (3) is hinged to the center of the large furnace door (1), and a tubular pull handle (4) is fixedly connected onto one openable side of the the small furnace door (3). The small furnace door used for observing conditions in a furnace is additionally arranged on the large furnace door so that the opening times of the large furnace door are reduced, energy is saved, consumption is reduced, and operators can be protected from being hurt.
Description
Technical field
The utility model relates to fire door, relates in particular to a kind of double-door oven port.
Background technology
Boiler is a kind of energy conversion, to the energy of boiler input the forms such as heat energy of chemical energy in the fuel, electric energy, high-temperature flue gas are arranged, and through the boiler conversion, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy.Fire door is as soot emissions in the control stove, and the visual plant of control atmosphere pollution is the requisite part of boiler.The duration and degree of heating must be in an appropriate zone and just is conducive to the carrying out that react in the stove, existing fire door can only be opened fire door during the duration and degree of heating in observing stove, cause the heat in the stove to overflow, and has increased energy consumption, and may cause operating personnel and burn, be unfavorable for energy-saving and cost-reducing and safety in production.
The utility model content
Problem to be solved in the utility model is that existing fire door must be opened during situation in observing stove, causes furnace heat to overflow, and a kind of energy-saving and cost-reducing double-door oven port is provided for this reason.
The technical solution of the utility model is: a kind of double-door oven port, and it comprises large fire door, and described large fire door can be opened a side and be connected with tubular handle, and large fire door central authorities are hinged with little fire door, and described little fire door can be opened a side and be connected with tubular handle.
The improvement of such scheme is to be inserted with between the tubular handle of the tubular handle of described little fire door and large fire door to make little fire door close more closely iron bar.
The beneficial effects of the utility model be little fire door by having additional situation in the observable stove at large fire door to reduce large door opened number of times, energy-saving and cost-reducing, and can avoid operating personnel to come to harm.
Description of drawings
Fig. 1 is the utility model schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model comprises large fire door 1, and described large fire door 1 can be opened a side and be connected with tubular handle 2, and large fire door 1 central authorities are hinged with port door 3, and described port door 3 can be opened a side and be connected with tubular handle 4.
In order better to guarantee the seal of little fire door, between the tubular handle 2 of the tubular handle 4 of port door 3 and large fire door 1, be inserted with and make port door 3 close more closely iron bar 5.
When using the utility model, in observing stove, take off the iron bar 5 between the tubular handle 2 of the tubular handle 4 of port door 3 and large fire door 1 during situation, open port door 3 with tubular handle 4, when adding materials in to stove or sweep in the stove health, needs can open large fire door 1, observe like this and operate both separately, reduce the opening times of large fire door 1, reduced the loss of furnace heat, reduced operating personnel's risk.
Claims (2)
1. double-door oven port, it comprises large fire door (1), it is characterized in that described large fire door (1) can open a side and be connected with tubular handle (2), large fire door (1) central authorities are hinged with little fire door (3), and described little fire door (3) can be opened a side and be connected with tubular handle (4).
2. a kind of double-door oven port as claimed in claim 1 is characterized in that being inserted with between the tubular handle (2) of the tubular handle (4) of described little fire door (3) and large fire door (1) and makes little fire door (3) close more closely iron bar (5).
