Abstract

The utility model relates to a movable quick-change coal-fired machine which is used on the industrial coal-fired reverberatory furnaces of an annealing furnace, a roasting furnace, a forging furnace, etc. The movable quick-change coal-fired machine comprises a motor, a decelerator 8, a coupler 9, a bearing seat 10, a coal stoking bucket 12, a coal transferring barrel 11, a combustion bucket 14 and a dividing body 15, which are arranged on a flat car 7 and can be moved beneath the combustion room 16 for use or drawn from the combustion room 16 for cleaning and maintenance. The coal transferring barrel 11 and the dividing body 15 are all in the structures of movable covering plate 18, 17, which is convenient for cleaning the inner cavities. Bearings on both ends are screwed and positioned in the bearing seat 10 which is positioned outside the coal transferring barrel 11, and the fault in which the coal powder presses into the bearings is eradicated.

Description

Movable quick-change coal-fired machine

Portable quick change coal burning machine is the equipment that is used on the industrial coal-fired reverberatory furnaces such as annealing furnace, oven, forge furnace.

The coal combustion of counter-burning coal-fired stove is abundant, the stove smoke medicining dust-removing effect is good.But known counter-burning coal-fired machine (referring to Fig. 1) is to build in the combustion chamber (5) of stove.Burning bucket (4) inconvenience cleaning.When safeguarding coal burning machine even will remove combustion chamber (5) and just can carry out.Particularly be in the sub-conductor (6) in the combustion chamber (5), its cover plate is to be welded on sub-conductor (6) body, and coal dust, coal ash can't be cleared up after falling into its inner chamber; Adding has two and pulls out coal freighter (3) in the coal bunker (2), structure is complicated; The bearing of defeated coal both helical ends easily causes spiral mechanical disorders such as " stuck " because of coal dust is pressed into bearing in coal delivery cylinder (1).Make the counter-burning coal-fired stove of this good benefit be difficult to promote the use of.

The purpose of this utility model be address the above problem and provide a kind of rational in infrastructure, be convenient to keep in repair, use in the few portable quick change coal burning machine of fault.

Narrate the utility model below in conjunction with accompanying drawing:

Fig. 1, known counter-burning coal-fired machine structural representation;

Fig. 2, portable quick change coal burning machine structural representation;

Fig. 3, portable quick change coal burning machine vertical view;

Fig. 4, known sub-conductor structure chart;

Fig. 5, well-behaved conductor structure figure;

Fig. 7, detachable removable cover coal delivery cylinder sectional drawing;

Movable quick-change coal-fired machine by motor and decelerator (8), shaft coupling (9), bearing block (10), coal delivery cylinder (11), add coal bunker (12), burning bucket (14), sub-conductor (15), flatcar (7) etc. and form. Add the top that coal bunker (12) is positioned at coal delivery cylinder (11) one ends. Communicate and combine as a whole with coal delivery cylinder (11). Add and be provided with one in the coal bunker (12) and pull out coal freighter (13); Burning bucket (14) is positioned at the below of stove combustion chamber (16), the top of coal delivery cylinder (11) other end. Communicate with coal delivery cylinder (11) and with flange connect; Sub-conductor (15) is positioned at burning bucket (14), is connected as a single entity with burning bucket (14), and sub-conductor (15) has a removable removable cover (17); Spiral in the coal delivery cylinder (11) is bearing on the bearing block (10) by the bearing that is positioned at the outer two ends of coal delivery cylinder (11). Coal delivery cylinder (11) bottom is detachable removable cover (18) structure, and removable cover (18) can be divided into several sections, uses respectively bolted on cylindrical shell (19).

Motor and decelerator (8), shaft coupling (9), bearing block (10), coal delivery cylinder (11), add coal bunker (12), burning bucket (14), sub-conductor (15) and all be installed on the flatcar (7), flatcar (7) can be mobile at the track of stove combustion chamber (16) below, they can move on to easily that below, combustion chamber (16) is used or from the combustion chamber (16) below haul out and clear up and overhaul.

When using portable quick change coal burning machine, earlier it is moved under the coal-fired reverberatory furnace, burning bucket (14) is docked with combustion chamber (16), air outlet aligns the air port of burning bucket (14), the coal that adds coal bunker (12) is sent into coal delivery cylinder (11) through pulling out coal freighter (13), spiral in the coal delivery cylinder (11) is transported to burning bucket (14) below with coal, be pushed into combustion chamber (16) through sub-conductor (15), because the fire grate that is provided with between burning bucket (14) and combustion chamber (16) is cellular, so have only a small amount of tiny coal dust and coal ash to fall in the burning bucket (14), can regularly open the other ash hole of burning bucket (14) and remove.When needing maintenance or cleaning inner chamber, combustor can be shifted out and carry out.

Advantage of the present utility model:

1. combustor separates with the combustion chamber of coal furnace, when needing cleaning or maintenance, can shift out from the below, combustion chamber easily, and needn't tear the combustion chamber open;

2. coal delivery cylinder is detachable, and the removable cover of its underpart is formed by several sections, when needing the cleaning tube inner chamber, will not haul out by whole defeated coal spiral, just can carry out as long as take several sections cover plates apart, has not only made things convenient for, but also light and handy;

3. the bearing of defeated coal both helical ends is arranged on outside the coal delivery cylinder, has eradicated because of coal dust is pressed into to cause the fault of failing coal spiral " stuck " in the bearing;

4. the sub-conductor in the burning bucket has adopted the removable cover that can take off, and both has been convenient to the processing of cover plate, is convenient to remove the coal dust and the coal ash that are scattered in the sub-conductor inner chamber again.
