Description

Stalker Incinerator Device with Parallel Oscillating Grate {The Driving System of Parallel Pitching Stocker}

The present invention relates to a waste conveying device of a stalker-type incinerator device for incineration of waste, wherein a main shaft for driving the driving grate is installed in the rear of the driving grate by connecting with a driving cylinder, and the front thereof is guided by a rail and a roller. The present invention relates to a stocker type incinerator apparatus.

Stocker-type incinerators are basically composed of three to four grate stages (dry stage, combustion stage, and post-combustion stage). Each grate consists of a fixed end, drive end, shaft, drive arm, lever, fixed bar, drive bar, roller, rail, grate and hydraulic cylinder, and the waste incinerated in the incinerator by the unique operation of each component. It burns and moves efficiently.

The most commonly used technology in Korea by incineration of waste is the use of stocker type incinerators. The grate composition and driving principle are that the grate is arranged in a stepped manner. Stokers that are transported little by little along the stairs are widely used.

However, in the case of the grate which is constructed in a stepped manner and driven by the forward and backward movement of the drive grate, a gap may occur between the drive grate and the fixed grate, and this gap may cause iron drift and foreign matter, which may cause damage to the grate frame and the support. Foreign substances released into the gaps can cause fires or cause great dropouts.

In addition, in the case of a stalker-type incinerator composed of stepped grate, the driving grate and the fixed grate are installed alternately in a row, and the driving grate increases the great wear of each grate by moving forward and backward between two fixed grate. And the grate of the fixed grate is a structure that is hung on each support bar, the frame and steel frame may be damaged by receiving a lot of load during waste accumulation by clinker (clinker) to each grate.

In the conventional driving method, the problem of clinker accumulation on the furnace wall frequently occurs, and the driving of the grate causes difficulties in waste transport and incinerator continuous operation due to damage of the furnace wall refractory caused by friction with the incinerator sidewalls.

The present invention is to solve the problems occurring during the forward and backward movement of the conventional stair stocker and the drive device as described above to configure the grate drive method as described below to be efficient in the operation and maintenance of the incinerator.

First, the main shaft installed in the driving grate is installed at the rear end of the stocker in consideration of the waste conveying direction and inclination, and the driving arm is installed downward to naturally drive even with a small driving force of the hydraulic cylinder. It is configured to be able to stir.

Secondly, the roller installed on the auxiliary shaft is configured to move the frame connected to the auxiliary shaft in a reciprocating manner as if the main shaft is slid from the top of the roller so that the drive grating can be moved smoothly with less force. It is designed to rotate together to minimize frictional load with the rail.

Third, iron drift or foreign matter which is not incinerated during operation of the incineration facility can be prevented by the arc motion of the driving device, which prevents the driving device from being caught by the gap of the grate frame when driving the driving device. The contact portion of the great rail is inclined in the form of V to allow the right and left flow to be somewhat reduced, thereby eliminating the phenomenon of iron drift between the driving grating and the fixed grating during operation.

Fourth, after arranging the arrangement of the driving grate and the fixed grate alternately in the vertical column instead of the horizontal row, the grate was designed to be installed on the upper part of the grate frame, thereby removing the great wear loss due to the interference between the grate when the grate is driven.

Fifth, the side grate can be installed between the inner side shaft part of the incinerator and the driving grate to eliminate the damage of the furnace wall refractory caused by the grate drive, and the air injection hole is installed at the upper side and the side of the side grate to provide high speed of combustion air. It was designed to prevent the formation of clinker on the inner side of the incinerator by allowing the furnace to flow into the side of the incinerator.

The stocker type incinerator device according to the present invention is a fixed grating fixed to a predetermined angle and spaced apart by a predetermined interval, a drive grating installed at a similar inclination between the fixed grate and driven back and forth, and one end of the lower side of the driving grate A lever installed to rotate, a main shaft installed to rotate the other end of the lever, a drive arm having one end fixed to the main shaft, and a drive cylinder fixed to the other end of the drive arm; It is characterized by.

Here, the rail is fixed to the front lower portion of the drive grating, the rail is configured to contact the roller fitted to the auxiliary shaft fixed to the lower portion, the rear of the drive grate according to the drive of the drive cylinder is called by the lever And the front may move linearly along the rail. At this time, the auxiliary shaft is designed to rotate together with the roller to minimize friction with the rail.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

First, referring drawings, Figure 1 shows a side view of the drive of the stocker type incinerator according to the present invention, Figure 2 shows a front view of the drive of the stocker type incinerator according to the present invention. 2 and 4 are cut to the left side based on the secondary shaft and the right portion is cut relative to the main shaft.

The configuration of the stocker type incinerator according to one embodiment of the present invention is based on the main shaft (5) in the linear motion of the cylinder (3) in the linear motion of the drive arm (4) connected to the main shaft (5) in the main shaft ( 5) arc motion, the main shaft (5) and the drive grate frame (2) by connecting the lever (6, 7) to the drive grate frame (2) is configured to arc motion, and the cylinder (3) and The roller 10 is installed on the unconnected auxiliary shaft 8 to connect the driving grate frame 2 with the rail 9 so that the rail 9 connected with the auxiliary shaft 8 during the arcing movement of the main shaft 5 can be made. ) Is configured to allow a linear motion on the roller 10, the auxiliary shaft 8 is rotated with the roller 10 to minimize friction. Further, the drive grate frame 2 and the fixed grate frame 11 are alternately repeatedly installed, and the grate 1 is installed on the upper part of each grate frame, and the side grate between the incinerator inner surface and the drive grate frame 2 is installed. 14) was installed.

That is, the lever 6 rotates around the main shaft 5 in accordance with the operation of the driving cylinder 3 to perform arc motion, and accordingly, the rear of the fixed grate frame 2 arcs and moves forward. Is driven in a straight line by the operation of the rail 9, the auxiliary shaft 8 and the roller 10. As a result, the waste on the top of the grate 1 gradually moves forward. Referring to FIG. 2 during this operation, since the roller 10 of the auxiliary shaft 8 is fitted into the V-shaped groove of the rail 9, a slight left and right flow is possible in the axial direction of the auxiliary shaft 8. Driven in the state.

The driving device and auxiliary equipment of the stocker type incinerator according to the present invention have the following effects.

First, the size of the drive device capable of overcoming and driving the weight of the waste and the drive unit is selected according to the installation position of the main shaft connected to the drive device in the drive grate. According to the present invention, the installation position of the main shaft is installed at the front end of each stocker, and the driving arm is installed downward so that the waste can be naturally transferred and agitated even by operation with less driving force of the hydraulic cylinder by the waste conveying direction and tilting. Configure it to be.

Second, by installing rollers instead of levers or other fixed parts between the auxiliary shaft and the frame of the drive grate, the grate drive is driven with less force by configuring the drive grate frame to slide on top of the roller of the rotating auxiliary shaft when the main shaft is driven. In order to facilitate the operation of the system, an appropriate size driving device was configured, and economical capital investment cost and operation cost were required.

Third, iron drift or foreign matter which is not incinerated during operation of the incineration facility may be interrupted by the operation of the hydraulic cylinder, which is the driving device, to hinder the driving of the drive device. The linear movement of the auxiliary shaft works in parallel to effectively prevent the problem of iron drift or foreign material jamming between the grate, and the roller and the great rail of the auxiliary shaft are inclined in the form of a V to allow left and right flow. Iron drift has been eliminated between the driving grate and the fixed grate.

Fourth, only the minimum related parts such as levers and clamps are installed inside the incinerator for effective coupling between the driving grate and the fixed grate and each shaft, and most other components are installed outside the incinerator side for convenient maintenance during operation or inspection of equipment. In addition, by minimizing the drive inside the incinerator, the operation failure of the incinerator caused by the failure of the drive is fundamentally solved.

Fifth, since the driving grate and the fixed grate are arranged in the vertical column instead of horizontally, there is no interference between each grate, so that the loss caused by the wear of the grate installed in the upper part is removed at the time of driving the grate, and between the grate and the grate frame Fixing with bolts or other parts effectively prevents the fall of the grate.

Sixth, between the inner side of the incinerator and the grate, side grates with air injection holes for combustion are installed on the upper side and the side so as not to interfere with each other by providing a gap between the driving grate and the inner wall of the incinerator so that the fire loss of the refractory caused by the grate driven is In order to prevent the formation of clinker on the side wall by injecting a high velocity combustion air into the incinerator side wall.
