Abstract
The utility model provides an improved stove door of a coal briquette furnace, comprising a furnace door frame body, a furnace door, an adjustable air blade and a hinge structure composed of a screw, a spring, a washer, a nut, a rivet, etc., overcoming the phenomenon of digging slag from the edge slot of a furnace door for easily pulling the door due to slag clogging, and the phenomenon of non-burning and over-burning of the molded coal when the stove is enabled. When the fire is sealed, the molded coal is controlled in the dormancy state. The firing can be implemented, when the furnace door is opened. The utility model is in particular suitable for coal briquette stove of the extensive application type.
Description
The utility model relates to a kind of improved moulded coal stove and accessory.
Under the call of State Council and various places government, town and country are burnt with the user of moulded coal increasing.Burning has advantages such as sufficient combustion, coal utilizaton rate height, air pollution be low with moulded coal.
In the market the moulded coal stove and accessory of Xiao Shouing have cast iron, galvanized iron and enamel etc.The characteristics of these stove and accessorys all are sliding doors (about or go up drop-down), and wherein the deficiency of Cun Zaiing has following 2 points:
(1) draw and dig the slag inconvenience, slag is easily filled in fire door along groove, and sliding door is bothersome.
(2) be difficult to after fire door is banked up a fire moulded coal is controlled at " dormancy " state, " suppressing dead " or " burning " phenomenon appear in moulded coal when enabling stove and accessory, cause worry for the people of being eager with fire, and adverse effect is come in the popularized type ribbing.
The utility model is at above-mentioned 2 deficiencies, and the fire door of stove and accessory is improved: the fire door framework is protruded body of heater, makes tambour door structure into the fire door framework and fire door has respectively been done the ears or side handles of a utensil, and rivet passes the hinge type structure in ears or side handles of a utensil hole, installs adjustable air intake sheet on fire door additional.
Characteristics of the present utility model are: this is a kind of fire door of hinge type structure, and fire door framework (11) is protruded body of heater (10) ((10), (11) are the cavity of one), sees fire door framework (11) by two sides, and it is one up-narrow and down-wide trapezoidal that its outline line is.Configuration and adjustable air intake sheet its center line same quantity, that divide equally fresh air inlet concentric on the fire door with centre bore.Screw (4) is passed packing ring (6), spring (5), and adjustable air intake sheet (3) is gone up on fire door (1), rotate adjustable air intake sheet degree of tightness appropriateness after, back tightening nut (7).The outer rim of adjustable air intake sheet (3) have one section with the concentric arc gap of centre bore and can be for the nail handle that rotates cowl flap, (1) Shang ， Pinch and occurs through hole, crescent moon hole and blind hole when the nail handle rotates air intake sheet (3) the last fire door at the arc gap place of stop screw (2).
Mentioning handgrip (8) fire door (1) when burning with moulded coal opens wide.Air intake sheet (3) is rotated position in through hole, crescent moon hole and blind hole respectively, cover fire door, own wt and fire door framework (11) applying sealing because of fire door (1), micro-air enters burner hearth by the fresh air inlet of air intake sheet control, just can reach the effect that use " slow fire " reaches " dormancy " respectively.
Fire door (1), fire door framework (11) are by the pig iron or other metal material, sheet metal manufacturing, adjustable air intake sheet (3) is made by the ferrous metal thin plate, and stop screw (2), screw (4), packing ring (6), nut (7), rivet (9) are all made with steel.Spring (5) is made by elastomeric material.Handgrip (8) with the steel manufacturing or with fire door (1) cast solid.
Applying plane when the B face of the A face of fire door (1) and fire door framework (11) is banking reaches the flatness requirement through the method for machining, hot investment casting or punching press.
The improvement fire door of this moulded coal stove and accessory can be used as the universal component of stove and accessorys such as cast iron, galvanized iron, enamel.Though increase is arranged on the manufacturing process cost slightly, overcome above-mentioned 2 deficiencies for the users that burn with moulded coal, this will play positive facilitation to promoting to burn with moulded coal.
Accompanying drawing 1 is structural representation of the present utility model (that is front view), and Fig. 2 is the left view of Fig. 1.
