Description

Coal Boiler

The present invention relates to a coal boiler, and more particularly, to a coal boiler equipped with an automatic input function of coal and pulverization of coal ash, as well as the discharge of coal ash.

In general, a heating system includes a small stove that heats fuel by burning fuel directly, a fireplace and a radiator indoors, and steam heating that is heated by steam or coma made from an outdoor boiler. Hot water heating and heating that sends high temperature air to the room with heat, steam, hot water, etc., ie, warm air heating, air conditioning walls, floors and ceilings, and pipes are put into the walls and floor ceilings. There are various methods, such as radiant heating, in which a surface temperature is raised to heat.

In small-scale heating which burns fuel directly, it is a method to burn fuel such as coal wood charcoal city gas oil in a furnace or stove installed in the room or to raise room temperature by electric stove using heating wire, Used for small heating such as offices,

The above method is to generate the heating effect by radiant heat and convection heat from the furnace or stove. In order to evenly heat the entire air in the room, a device having a large amount of convective heat is preferable. It is good to have a type of radiant heat device.

In connection with the above-described heating devices the boiler according to the invention

It is a device that generates steam by combusting fuel such as petroleum and coal and transmitting its combustion heat to water, and is classified into cylindrical boiler water pipe boiler and special boiler according to the characteristics of the structure.Briquet boiler, oil boiler, Various boilers such as coal boilers and nuclear boilers are being made,

Generally, oil boilers and coal boilers are typical types of boilers for home use, and can be commonly used in house complexes and the like due to economic reasons, such as installation and maintenance costs, compared to other boilers.

In the present invention, as an improved form of the coal boiler, the input of coal, which is used fuel, is free, and the coal grinding machine and the automatic discharge of the coal ash are manufactured in such a form that the convenience of using the coal boiler is to be increased.

The coal boiler 1 according to the present invention is composed of an input unit A for largely supplying coal as fuel, a combustion unit B for burning the supplied coal, and a recoal discharge unit C for discharging the burned coal.

The input unit A is provided with a storage tank 2 having a storage amount sensor 77 for storing coal and detecting the amount of coal stored in the upper portion of the case 16, the storage tank (2) of Below, the hopper 20 for supplying coal to a combustion part is integrally formed.

A gun bearing 3 is installed below the hopper 20 to supply coal to the combustion chamber 100, and the conveyor 3 is a chain gear 70 and a chain that receive power from the controller 50. (71) Allow the drive to receive power from the union.

The combustion unit B is provided with a hot water heating unit 30 installed below the conveyor 3 and a combustion chamber 100 for burning coal supplied below the hot water heating unit 30.

The hot water heating unit 30 has an inlet port 31 for supplying hot water to be heated and an outlet port 32 for discharging the heated hot water, and a longitudinal direction between the inlet port 31 and the outlet port 32. By installing a plurality of spiral tube (99) to be able to heat the supplied water with hot water.

The combustion chamber 100 includes an opening and closing port 17 and a re-carbon discharge monitoring sensor 11 for coal ignition, and the input pipe 27 connected to the conveyor 3 so as to receive coal and to prevent heat loss. The discharge cover 6 is provided in a cylindrical shape so as to be upward.

Below the combustion chamber 100, a grinding roller 70 for pulverizing the re-coal of the supplied coal, and a discharge roller 80 for easily pulverizing the burned coal are interlocked with each other.

Side of the grinding roller 70 and the discharge roller 80 is further provided with a driven gear (7, 8) is connected to the chain gear 60 and the chain 63 combination to receive power from the controller 50 The gear 44 allows power to be transmitted.

The discharge port 81 formed below the grinding roller 70 and the discharge roller 80 is vertically installed at the side of the combustion chamber 100 to be crushed by being connected to the discharge part 34 containing the screw 39. The ash is stored in the ash storage container 35 formed on one side of the case 16.

The screw 39 is driven by a gear box 58 installed below, the gear box 58 is a chain gear 60 and a chain (60) for driving the grinding roller 70 and the discharge roller (80) 63) to operate by the combination of the chain 63 and the chain gear 60 connected to the combination.

As another embodiment of the ash recharging portion (C), as shown in FIG. 3, a guide bar 81 is separately provided on the crankshaft (13) associated with the drive gear 44 of the recharging discharge portion (C) so that one side is cranked. The other side of the shaft 13 is fixed to the side of the re-carbon distribution plate (9).

Referring to the operation of the present invention configured as described above are as follows.

The conveyor 3, which is operated by the combination of the chain gear 70 and the chain 71 at regular intervals by the operation of the controller 50, always automatically supplies a certain amount of coal into the combustion chamber 100.

The burnt ash is pulverized by the drive gear 44 driven by the controller 50 at regular intervals and the grinding roller 70 driven therethrough, and is pressed again to the discharge roller 80 to be finely. It is crushed and discharged.

The ash which has passed through the above process is stored in the ash storage container 35 through the operation of the screw through the outlet to facilitate the treatment of ash.

The series of processes described above enable the automatic input and discharge of coal at regular intervals by the controller 50 so that the coal quantity sensor 77 always retains a certain amount of coal, and the re-carbon emission sensor 11 The controller 50 by) maintains a constant amount of coal in the combustion chamber in the combustion chamber 100 at all times.

In another embodiment, the ash recharging method is ash recharging discharged downward by the operation of the discharge roller 80 as shown in FIG. 3. The recharging storage container 35 is operated by vertically operating the recoal distribution plate 9 by the guide bar 81. To be automatically distributed and stored.
