Description

Technical Field

[0001] The invention relates to garbage incineration equipment, in particular to a swing feeding device and a feeding method for a garbage incinerator. Background Art

[0002] During the combustion process, the waste incinerator must frequently observe the combustion conditions in the furnace and control the thickness of the material layer in the furnace, which requires that the waste be evenly distributed when feeding. If the feeding is too concentrated, it is easy for the waste to agglomerate, burn incompletely, and burn unevenly, which greatly reduces the combustion effect, greatly reduces the resource utilization and reduction effect of biochemical waste, and even has an adverse effect on the combustion conditions of the entire waste incineration system. In addition, in actual applications, since grate waste incinerators have more advantages than fluidized bed waste incinerators, many fluidized bed waste incinerators need to be transformed into grate furnaces, and the transformation of the feeding system is an important part of it. Uniform feeding is an important prerequisite for stable incineration, so it is necessary to improve the centralized feeding of waste incinerators. Summary of the invention

The first track is arc-shaped, the first driving wheel is arranged on the first track, the first driving wheel is connected to the driving assembly, and the driving assembly drives the first driving wheel to move to both sides relative to the first track, thereby driving the hopper to swing.

The second track is an arc-shaped rack track, the second driving wheel is a gear, the second driving wheel is meshed with the second track, the second track is connected to the hopper, and the driving assembly is connected to the second driving wheel. The driving assembly drives the second driving wheel to move left and right so that the second track drives the hopper to swing left and right.

[0009] Furthermore, it also includes multiple groups of second guide components, the second guide components include a second guide wheel, a second guide wheel shaft, and a second guide wheel bracket, the second guide wheel shaft is connected to the second guide wheel bracket, the second guide wheel is rotatably connected to the second guide wheel shaft, the second guide wheel abuts against the side of the second track, the second guide wheel bracket is connected to the bracket, and the multiple groups of second guide components are evenly arranged along the arc of the second track.

[0010] Furthermore, second position sensors are respectively disposed at both ends of the second track.

[0011] Furthermore, the driving assembly includes a servo motor and a reducer, the output end of the servo motor is connected to the reducer, and the output end of the reducer is connected to the first driving wheel or the second driving wheel.

[0012] Furthermore, it also includes a first connecting rod and a bearing seat, wherein the bearing seat is connected to the bracket, and one end of the first connecting rod is connected to the hopper, and the other end is connected to the bearing seat.

[0013] The present invention adopts the feeding method of the above-mentioned swing feeding device of the garbage incinerator, comprising the following steps:

[0014] A set material level line of the feeding channel is predetermined, the feeding channel is evenly divided into n channel sections along the width direction, each section has a length of L1, the material level in each channel section is obtained in real time, a real-time material level line of the feeding channel is generated, the real-time material level line is compared with the set material level line, and N groups of height difference values ​​ΔH between the real-time material level line and the set material level line are obtained,

[0015] The normal operating speed of the servo motor is set to V, the average operating speed of each channel section L1 is set to V', the lateral section width is set to W, and the correlation coefficient K between V and V' is set.

[0043] The present invention adopts the feeding method of the above-mentioned swing feeding device of the garbage incinerator, such as Figure 8 , Fig. 9 As shown, the following steps are included:

[0044] The set material level line 72 of the feed channel 07 is predetermined, and the material level line 72 is a horizontal line. The feed channel 07 is evenly divided into n channel sections along the width direction, and each section has a length of L1. During the transportation of the waste incineration materials, the material level in each channel section is obtained in real time, and the real-time material level line 71 of the feed channel 07 is generated.

[0047] When ΔH=0, V′=V / K(ΔH, W, L1), ΔH=0, K value is equal to 1, and the servo motor 331 runs at speed V.
