KR200272739Y1 - Ash remover for fan heater using coal - Google Patents

Abstract

In the case of using a liquid fuel, there is no residue after combustion, so it is not necessary to have additional equipment such as a combustion material removal device, whereas in the case of a hot air fan using solid fuel such as lignite, the complexity, power, and cost of the device due to the supply of fuel and the discharge of the combustion material are frequent. Use has been avoided due to breakdowns.

Therefore, when the proper combustion material removal device is provided, it is possible to use solid fuel which is much lower in terms of fuel cost. Therefore, the present invention provides a constant angle to the grate of the combustion chamber to solve this problem. It can be discharged out of the combustion chamber by the discharged combustion material is characterized in that it can be collected in the combustion material recovery box by the scoops interlocked with the fuel supply device.

Description

Ash remover for fan heater using coal}

In the case of a hot fan or boiler using a solid fuel, a method for supplying fuel and removing a combustion material is required as compared to a hot fan and a boiler using a liquid fuel. Conventional methods include feeding shaped coal, such as briquettes to the top, discharging the burned ash to the top, and some improved methods to discharge the burnt coal to the bottom. In such a case, a lot of labor is required to input fuel and discharge combustibles, and a certain time management is required, and alternatively, powdered coal or granulated coal stored in the hopper is supplied to the combustion chamber with a screw conveyor, and the combusted material dropped to the bottom of the grate floor. There is a method of scraping by using a motor, etc. and discharging it by using a screw conveyor as a combustion ash recovery box. However, it is mechanically complicated, and the bottom of the grate of the combustion chamber is high temperature due to radiant heat, so that the failure of the rotating body such as a motor is frequent and fuel supply is performed. High power consumption for driving motor, scraping motor, combustor discharge motor.

The present invention to solve the above problems,

It is possible to supply fuel and discharge of combustibles by the information value set in the controller, and give a certain angle of inclination to the grate installed inside the combustion chamber, and when fuel enters the fuel supply device, the combustor is gradually pushed out from the bottom of the grate. Falling out of the combustion chamber by gravity, it is configured to be collected in the combustion material recovery device by a screw interlocked with the fuel supply device, the structure is simple and is driven by one motor for the fuel supply device to reduce power consumption. .

1 is a block diagram according to the present invention

Figure 2 is a perspective view of the grate according to the present invention

In order to achieve the above object, the fuel supply device 9 installed at the lower end of the hopper 7 installed on the outer wall of the combustion chamber 1 will be described with reference to the accompanying drawings. It is installed to supply a certain amount of fuel on the grate 10, the motor 8 for driving the fuel supply device 9 is connected to the combustion material discharge device 13 to open the combustion material at the same time as the fuel supply The material outlet 12 is dropped by gravity, characterized in that the combustion material can be discharged to the combustion material recovery box 14 by the combustion material discharge device (13).

In addition, since the grate 10 of the combustion chamber has a predetermined angle of inclination, it is gradually pushed as fuel is supplied from the fuel supply device 9 so that the combustion material can easily slide down from the bottom of the grate 10, and the grate 10 The floor has a combustion air supply hole smaller than the size of the fuel to promote combustion and the amount of air supplied for combustion is also linked with the controller to adjust the supply amount so as to increase the thermal efficiency.

Combustion material discharge device according to the present invention having the structure as described above is mechanically simple, easy to control automatically, less trouble, less power consumption, high thermal efficiency, and Discomfort due to the discharge can be eliminated, and it does not require labor for the supply of fuel or the discharge of combustion materials for a long time.

Claims (1)

The fuel supply device 9 is operated by the motor 8 in a structure interlocked with the fuel supply device 9 attached to the lower end of the fuel storage hopper 7 according to the set value of the controller 18. When the fuel is supplied to the grate 10 of, the combusted combusted material is supplied in advance in time and is pushed out of the grate 10 and has a proper inclination so as to be discharged to the combustion ash outlet 12 by gravity, The discharged combustion material has a structure in which the combustion material can be collected into the combustion material recovery box 14 by the combustion material discharge device 13 connected to the motor 8, and the grate 10 is composed of two layers and is inclined. The combustion material discharge apparatus, characterized in that the structure has an air hole so that the combustion air can be supplied.
