Abstract

The present invention relates to a briquette boiler device, and more particularly, to a large-capacity briquette boiler device for heating in a facility house. In the past, it was randomly shot into a combustion chamber, but pulverizing with a grinding blade installed at the bottleneck part of the combustion chamber is a bottleneck. The coal briquettes were not easily lowered on the grinding blade due to entanglement with each other, and in the case of almost burned carbon materials, especially lignite and anthracite coal, there is considerable thermal power remaining on the oxidized and remaining carbon materials, so the blades for grinding the carbon materials are easily deformed or driven by heat. The bearing part was deformed by the thermal power, which greatly influenced the operation of the grinding blade, and even in the heat exchanger, the circulation motor was not operated due to the power failure, and the water was not forcedly supplied or the scale was not discharged due to water pressure. Although the heat transfer efficiency was reduced, the grinding feed screw and the grinding feed screw water pipe were Cooling water was added to prevent brittleness due to thermal power in the coal ash.In the case of a vertical heat exchanger structure with forced flow from top to bottom, the scale dropped from the top accumulates in the bottom of the heat exchanger so that the flow of water in the pipe is reduced. Although deteriorated, it is to provide a briquette boiler device to be easily discharged to the outside by the flow of water from the bottom to the top.

Description

Briquette boiler system {a briquet boiler system}

The present invention relates to a briquette boiler device, in particular to a large-capacity briquette boiler device for the purpose of heating in the facility house.

In general, briquette boilers load and burn several to tens of briquettes into the combustion chamber one by one, and then discharge the lower briquettes when discharging the burned briquettes, and then make the upper briquettes coincide with the lower briquettes again. There was a hassle.

The prior art utility model registration No. 0286529 briquette boilers are randomly shot into the combustion chamber, but the burnt briquettes are provided with a plurality of grinding blades on the outer circumferential surface of the bottleneck part of the combustion chamber. There was a briquette boiler installed, but because the coal briquettes were entangled with each other in the bottleneck part of the combustion chamber, briquettes could not be lowered on the grinding blade, so the pulverization of the briquettes could not be effectively expected.

In addition, of course, the coal briquettes which have almost been burned are used, but when lignite or anthracite coal is used as a combustion material, since significant thermal power remains in the oxidized and remaining carbon material, the thermal power in the lower portion of the combustion chamber is considerable. Therefore, the general grinding blade is easily deformed by heat, or the driving bearing portion thereof is deformed by thermal power, which has a great influence on the operation of the grinding blade.

In the heat exchanger, not only oil boilers but also briquette boilers are installed vertically with a type of heat exchanger pipe arranged at one or more stages horizontally, but the water supply is forced into the upper part of the heat exchanger pipe by a circulation motor or the like for heat exchange. Since it is discharged to the lower part of the pipeline and flowed back to the upper part of the heat exchanger, the vertical type heat exchanger can not be forcibly supplied to the vertical type of heat exchanger when the circulation motor is not operated due to a power failure, or it is scaled by hydraulic pressure. The heat transfer efficiency decreases due to no discharge of heat, and in the case of horizontally arranged heat exchanger, the corrosives that fall from the upper layer are laminated on the outer top of the lower heat exchanger channel, or the corrosives accumulated under the vertical pipe between the stage and the heat exchanger Stacked in pipeline to reduce efficiency as heat exchanger It became a seal.

The present invention, in view of the above, in the briquette boiler, in order to quickly replace the burned carbon material and the rapid pulverization treatment of the carbon material, first the combustion chamber structure is formed in the vertical type with the same diameter of the upper and lower parts, and the remaining carbon material Even if it is tangled, it is easy to fall downward, but the grinding device for processing carbon material adopts a grinding feed screw to pulverize the carbon material and discharge it to the outside to induce rapid treatment, and the thermal power of the carbon material transferred to the grinding feed screw In order to prevent brittleness of the grinding feed screw by using a grinding feed screw shaft as a hollow body to insert the cooling water to prevent brittleness by the coal fire.

On the other hand, in the case of the heat exchanger, the heat exchanger is formed vertically, but considering the problem of the scale accumulated in the vertical pipe between the end and the conventional water flow structure, in the case of the vertical pipe heat exchanger of forced flow type from top to bottom In the mechanical tank, the scale dropped from the upper part accumulates in the lower part of the heat exchanger, and the flow of water in the pipe is reduced, and in consideration of the heat exchange efficiency, the flow of water even when scale due to corrosion occurs. It is to provide a briquette boiler device to be easily discharged to the outside.

And a briquette input table 2 formed together with the opening / closing door 3 in an outer side thereof, wherein an inner channel part of the main body 1 is provided with a water passage 21 including a heat insulating material 22 to form briquettes 23. In the briquette boiler 100 having a combustion chamber that is randomly built in, the combustion chamber upper part has a spiral tube in the main body (1) having a vertical tube bundle heat exchanger (24) and a pulverization part (1a) that is separately coupled below it. Several grinding feed screw water pipes (19a) formed with a feeding screw (19) are penetrated through both sides of the grinding part (1a) by the flanges (8), and the rails (16) are provided on the ground in the front opening of the grinding part (1a). The upper part of the backing cart 14 received and drawn out by the roller 7 and the handle 15 attached to the floor by Vibration cam (18a) is attached to the vibration cam shaft 18 on the vibration motor (13) shaft attached to both ends of the outer side of the reload trolley (14b) resiliently installed in the recirculation grill (9) with a tension spring (18b) It is placed under the reclaim grill 9, and the refill grill inlet pipe 11 and the reclaim grill outlet pipe 12 are formed on the front side of the frame.

Referring to Figure 3 in more detail the structure of the heat exchanger 24, the heat exchanger 24 is to be installed in the combustion chamber upper end of the main body 1 of the rectangular box type, the channel 21 inside the left and right side plates ( In the 24b), two types of vertical and vertical distribution pipes 24c, which are formed by piercing the pipes, penetrate the upper plate 24a in the form of vertical pipe bundles.

On the other hand, as shown in Figure 2 and 4, from the grinding feed screw motor 25 mounted on the rear side of the grinding unit (1a) fixed to the flanges 8 on both outer sides of the grinding unit (1a), At one end of each of the grinding feed screw water pipes 19a driven by a chain (not shown), the grinding feed screw inlet pipe 7 is coupled to the coupling rotary socket 6 equipped with the grinding screw gear 20. The rotary socket 6 is equipped with a grinding feed screw water pipe (7a).

The coupling rotary socket 6 is a component known as a rotary connection coupling for passing a gas or liquid pipe through a hollow shaft as shown in FIG.

The bearing (not shown) of the flange 8 and the grinding feed screw 19 and the grinding feed screw water pipe 19a due to the heat of combustion affecting the grinding feed screw water pipe 19a due to the adoption of the coupling rotary socket 6. ) To prevent brittleness due to heat.

As such, in the present invention, the briquette boiler 100 is operated while continuously discharging the cooling water introduced through the grinding feed screw inlet pipe 7 through the grinding feed screw outlet pipe 7a.

In the operation of the grinding unit 1a according to the present invention, when the carbon material in the combustion chamber is to be burned and discharged, the grinding feed screw motor 25 is operated so that the even numbered grinding feed screws 19 are installed in opposite directions. Two pieces of the grinding feed screw gear 20 are assembled so as to rotate, and the chain is assembled by jumping the grinding feed screw gear 20 into the chain one by one, and the ash is received by the grinding feed screw 19 at the same time. The carbonaceous material which falls into the grill 9 and is not crushed is pushed out by the grinding feed screw 19 and then quickly discharged to the external redistribution lathe 10.

On the other hand, a few particles of the carbon material falling on the back plate (9) is immediately discharged to the bottom plate back 14, the coarse particles of coarse particles of the vibration cam shaft (18) formed on both sides of the bottom of the back plate (9) As the vibration cam 18a rotates intermittently by the vibration motor 13, the ash back 9, which is elastically supported by the tension spring 16b, is shaken up and down so that the coarse particles of coarse particles are easily discharged.

According to FIG. 7, which is an exemplary operating system diagram of the present invention briquette boiler 100 configured as described above, in the case of using several hundreds of sheets of briquettes as a combustor, grinding coal is replaced as much as replacing the burnt coal material. Considering that it is also difficult to put, as in the present invention, the coal briquette tray 2 in front of the opening / closing door 3 picks up a pallet 600 loaded with briquettes 23 of several tens to hundreds of units by a crane 500. The briquette boiler 2 is moved to briquette boilers and briquettes are easily moved.
