Description

Technical Field

[0001] The invention belongs to the technical field of waste treatment, and in particular relates to a boiler slag drying machine and a slag crushing method. Background Art

[0002] The dry slag machine can reduce, render harmless and recycle various wastes generated in the industrial production process.

[0003] Existing dry slag machines are generally single-stage or double-stage structures, so as to crush waste. However, the single-stage dry slag machine has a low crushing capacity. When the waste is large and hard, such as the coke formed by Xinjiang coal after blending, it is difficult to fully crush it through the single-stage dry slag machine, which can easily cause the dry slag machine to be blocked, affecting the crushing efficiency. Although the bipolar dry slag machine can fully crush larger and harder waste, it has a high operating energy consumption. If it encounters waste that is easy to crush, the bipolar dry slag machine will cause energy waste. In addition, there is generally a difference between the sizes of wastes adapted by the single-stage dry slag machine and the bipolar dry slag machine. Only by using the single-stage dry slag machine and the bipolar dry slag machine for crushing, it is inevitable that some wastes cannot be crushed.

[0004] Therefore, the existing dry slag machine has a poor slag crushing effect. Summary of the invention

[0026] A first rotating rod, one end of which is coaxially rotatably connected to the other end of the first connecting rod, and the other end of the first rotating rod is threadedly connected to a side wall of the shell away from the slag bucket.

The first slag crushing roller 131 and the second slag crushing roller cooperate with the corresponding auxiliary rollers 113, respectively, to crush the waste and improve the slag crushing effect.

[0067] It should be noted that the structural difference between the second slag crushing mechanism 140 and the first slag crushing mechanism 130 is that no accommodating cavity is provided at the corresponding position of the second slag crushing mechanism 140, and the other structures are the same.

[0068] Reference Figure 3The present invention also provides a slag crushing method, which uses the boiler slag dryer as described in any of the above specific embodiments, and includes the following steps: the first feeding part 200 conveys waste into the slag crushing chamber of the slag crushing part 100. According to the size of the waste, the slag crushing end of the first slag crushing mechanism 130 and the slag crushing end of the second slag crushing mechanism 140 are driven to move, so that the gap between the slag crushing end of the first slag crushing mechanism 130 and the slag crushing chamber and the gap between the slag crushing end of the second slag crushing mechanism 140 and the slag crushing chamber can be adapted to the size of the waste. When the size of the waste is smaller than the preset size, the slag crushing end of the first slag crushing mechanism 130 is driven to move in the direction close to the accommodation chamber until the slag crushing end of the first slag crushing mechanism 130 is accommodated in the accommodation chamber. The waste is continuously crushed, and the crushed waste is conveyed to the slag bin through the second feeding part 300.

[0069] Specifically, the first feeding part 200 is used to convey the waste to the top of the slag crushing chamber of the hopper 110, and at the same time, the reversing plate 111 is rotated to a preset position, so that the waste conveyed into the slag crushing chamber can fall from the top of the slag crushing chamber along the reversing plate 111. In addition, before the first feeding part 200 conveys the waste to the top of the slag crushing chamber of the hopper 110, according to the size of the waste, the first slag crushing roller 131 and the second slag crushing roller are driven by an external motor to move along the first chute 1331 and the second chute end respectively, so as to adjust the size of the slag crushing gap between the first slag crushing roller 131 and the second slag crushing roller and the corresponding auxiliary roller 113, so that the size of the slag crushing gap between the first slag crushing roller 131 and the second slag crushing roller and the corresponding auxiliary roller 113 can be adapted to the size of the waste. When the size of the waste is smaller than the preset size, that is, the slag can be crushed by the single-stage slag crushing structure, the first slag crushing roller 131 is driven to move toward the corresponding housing 120 until the first slag crushing roller 131 is accommodated in the corresponding accommodation cavity, so that the waste transported to the slag crushing cavity is only crushed by the second slag crushing roller. The first feeding part 200 continuously transports the waste to the top of the slag crushing cavity of the slag bucket 110, and the waste is crushed by the double-stage slag crushing structure formed by the first slag crushing roller 131 and the second slag crushing roller or the single-stage slag crushing structure formed by the second slag crushing roller only, so that the waste after the slag crushing falls into the second feeding part 300, and is then transported to the slag bin through the second feeding part 300.

[0070] It should be noted that the first feeding part 200 is a steel belt conveyor, and the second feeding part 300 is a bucket elevator, which are relatively common devices and are easy to install, set up and use.

[0071] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
