Description

Incinerator with vibratory grate {INCINERATOR HAVING A VIBRATION GRATE}

The present invention relates to an incineration apparatus. More specifically, by using the vibration force of the eccentric rotation of the unbalanced half-moon disk to improve the mixing of the waste contained on the grate to achieve a complete combustion, the vibratory grate to enable the transfer of the incineration material without a separate transfer means It relates to an incineration apparatus comprising a.

In order to dispose of solid waste (RDF) discharged from general households and various industrial facilities, a conventional landfill site has been secured and landfilled. It is recognized as the most modern and reasonable way. In other words, the incineration method reduces more than 95% of the volume of the waste, which is advantageous in that the volume of the waste to be finally disposed of is reduced, and that the potential energy of the combustible components in the waste can be recovered.

However, the incineration method has a burden of minimizing the generation of pollutants such as combustion gases (CO, NOx, etc.) due to incomplete combustion and local high temperature zones due to insufficient mixing of wastes.

Therefore, many attempts have been made to achieve complete combustion by incineration of the waste contained on the grate so that incineration is minimized.

For example, in the conventional incinerator, a cam or hydraulic cylinder is provided below the grate to swing the grate to induce mixing of the waste contained on the grate, or the movable grate and the fixed grate are combined to move the mixture while moving a certain distance. It is inducing. However, the grate of such a conventional incinerator has little or no mixing function besides the function of advancing the waste to the ash collecting side, so that the waste does not spread evenly on the grate, forming a pile in one place and thus incomplete combustion. The problem was not solved. In addition, in the case of the conventional incinerator using anthracite coal as a solid fuel, fine coal powder is manufactured and sprayed together with air in the combustion chamber to improve mixing, but there is a disadvantage in that a large amount of energy is consumed in order to pulverize the anthracite coal in the form of coal. .

The present invention has been made to solve the above problems, an object of the present invention is to achieve a complete combustion in a short time because the mixing of the waste is good, the incineration device for transporting the incinerator ash on the stocker to the ash receiving side without a separate transport means To provide.

An object of the present invention is to incinerate the stocker waste stacked on the hopper is mixed by the vibration means mounted on the lower side of the stocker to achieve complete combustion, the incineration material is transferred to the ash tray provided on one side of the stocker, The vibration means is achieved by an incinerator comprising an oscillating motor, a motor shaft, a bearing supporting the motor shaft, and an unbalanced half moon disk comprising an adjustment weight and a fixed weight inserted into the motor shaft.

Hereinafter, an incineration apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Referring to this, a hopper (1) into which waste is input is provided, and a spur (3) in which waste injected into the hopper (1) falls and is stacked is disposed below the hopper (1).

The stocker 3 may be a planar type in which a plurality of grate 2 pieces are configured in parallel (FIG. 1), and may be a staircase type in which the grate 2 forms a staircase (FIG. 2). On the other hand, in order to easily move the incineration material on the stocker 3 to the ash holder 5 side due to the vibration caused by the eccentric rotation of the unbalanced half-moon disk 11 according to the driving of the vibration motor 10, the grate has a predetermined angle α. It is preferable to tilt down.

In addition, a plurality of combustion air injection holes 4 are installed through the grate 3 to inject combustion air to facilitate combustion.

The ash holder 5 is provided on one side of the stocker 2 so that the incineration ash remaining after combustion is transported and processed.

On the other hand, the lower side of the stocker (2) is equipped with a vibrating means for vibrating the stocker (2), the vibration is made by the eccentric rotation to the unbalanced half moon disk 11 in accordance with the drive of the vibration motor (10). 3 is a cross-sectional view of a vibration motor including an unbalanced half moon disk according to the present invention, and FIGS.

The vibration motor 10 is mounted below the stocker 3 and has a motor shaft 13 supported by a bearing 12.

The unbalanced half moon disk 11 is defined as a fixed weight 14 inserted into both sides of the motor shaft 13 and an adjustable weight 15 that can be selectively fastened to the fixed weight 14.

The fixed weight 14 has an insertion hole 18a inserted into the motor shaft 13 at the center of the straight portion 14a, i.e., below, and has a plurality of fastening holes 17a inside the curved portion 14b. Dogs are formed. In addition, a screw hole 16 coupled to the motor shaft 13 is fixed to the upper surface center of the straight portion 14a. A screw is fastened to the screw hole 16 to press the motor shaft 13 to fix the fixed weight. do.

The adjusting weight 15 is also formed with an insertion hole 18b inserted into the motor shaft 13 at the center of the straight portion 15a, i.e., below, the fixed weight 14 inside the center of the curved portion 15b. A plurality of fastening holes 17b to be selectively fastened with the fastening holes 17a are formed.

However, the fastening holes 17a and 17b of the fixed weight 14 and the adjustment weight 15 are not limited in the number. That is, one fastening hole 17a may be formed in the fixed weight 14, and in this case, a plurality of fastening holes 17b of the adjusting weight 15 may be formed into the curved portion 14b to be selectively coupled thereto. Can be formed. Similarly, the fixed weight 14 may have a plurality of fastening holes 17a, in which case the adjustment weight 15 may be selectively coupled with one fastening hole 17b.

Assembly and operation principle of the vibration motor including an unbalanced half-moon disk is configured as follows.

When the fixed weight 14 is inserted through the insertion hole 18a at both sides of the motor shaft 13, it is fixed to the motor shaft 13 by the screw hole 16a. After that, the adjustment weight 15 is inserted into the insertion hole 18b in parallel with the fixed weight 14, and is selectively fastened by the fixing weight 14 and the fastening holes 17a and 17b. At this time, when the adjustment weight 15 is inserted in accordance with the fixed weight 14, as shown in Figure 4, the vibration of the vibration motor 10 is maximized, as shown in Figures 5 and 6 ) And the fastening angle of the fixed weight 16 increases, the vibration of the vibration motor 10 is gradually weakened.

That is, when the adjustment weight 15 is inserted in accordance with the fixed weight 14 as shown in Figure 4, the center of gravity of the unbalanced half-moon disk 11 is farthest on the axis, so that the motor 10 When the shaft 13 is rotated by driving, the rotational eccentricity of the unbalanced half moon disk 11 is maximized and the maximum amplitude is generated. However, when the fastening angle between the fixed weight 14 and the fixed weight 15 increases, as shown in FIG. 5, the center of gravity approaches the axis, and the amplitude becomes smaller, and the amplitude becomes smaller as shown in FIG. 6.

In addition, the amplitude value may be changed by the number of the fixed weight 14 and the adjusting weight 15. If a larger amplitude value is desired, the fixed weight 14 and the adjusting weight 15 are inserted into the motor shaft. You can increase the number.

On the other hand, the operation and effects of the incineration apparatus including the above unbalanced half moon disk 11 is as follows.

The dry garbage introduced into the hopper 1 through the drying apparatus not shown is stacked on the stocker 2, and is also subjected to the combustion process by the combustion apparatus not shown.

When the vibration motor 10 is driven by the application of an electric current, the unbalanced half moon disk 11 rotates while causing an eccentricity, and the grate 3 to which the vibration motor 10 is attached vibrates. Therefore, the vibration force evenly distributes the waste stacked on the stocker 3 on the stacker 3, so that good waste mixing is achieved and the combustion is active, and at the air inlet 4 for combustion for the purpose of combustion. The preheated combustion air is injected.

In addition, since the grate 3 is inclined at a predetermined angle α, the incineration ash is conveyed to the ash receiving section 5 naturally only by the vibration of the vibration motor 10 without a separate incineration ash conveying means.

Here, since the vibration angle can be changed by varying the fastening angles of the fixed weight 14 and the adjusting weight 15, the time to stay in the stocker 2 can be adjusted according to the type or size of the garbage.

In addition, when the amount of rubbish stacked on the stocker 3 is large, a large amplitude may be generated by a plurality of fixed weights 14 and adjustment weights 15 inserted into the motor shaft 13, and sometimes a motor shaft ( By inserting the fixed weight 14 and the adjustment weight 15 only on one side of 13), when waste is concentrated only on one side of the stocker 2, it is easy to disperse to the opposite side.

On the other hand, since a large amount of waste is normally stacked on the stocker 2 on the hopper 1 side and a small amount of waste flows on the stocker 2 on the ash collecting 5 side, vibration force suitable for each position is achieved. A plurality of vibration motors 10 may be installed.

In order to prevent the fall of garbage and fuel, it is preferable that a protective wing 19 which can adjust its height according to the size and type of the material to be burned is installed around the stocker 3.

The incineration device is supported by a support 20 formed at each corner.

According to the incineration apparatus including the vibrating grate according to the present invention, by vibrating the stocker up and down by the vibration force of the eccentric rotation of the unbalanced half-moon disk to achieve the complete combustion of the waste, according to the type and quantity of the waste It is a useful invention that can be changed. In addition, since the grate is inclined by α, it is possible to transfer the incineration ash to the ash collecting side by the vibration force without a separate incineration ash conveying means.
