[0002] Fly ash is the tiny ash particles discharged during the combustion of fuel, also known as fly ash or soot, which are fine solid particles in the flue gas ash produced by the combustion of fuel. Waste incineration is the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions, and turning it into residue or molten solid matter. Waste incineration facilities must be equipped with flue gas treatment facilities to prevent heavy metals, organic pollutants, etc. from being discharged into the environment again.

[0004] The above patent arranges the air intake, filtration and other structures in a square box, and the gap area in the square box is large, resulting in limited effect of absorbing fly ash. In addition, multiple transmission structures are used to achieve the purpose of air intake and screen wiping. This will not only increase the preparation cost of the equipment, but also increase the operating power consumption of the motor, and its practicality is poor. Utility Model Content

[0005] The purpose of the present invention is to provide a device for treating fly ash from incinerated garbage in order to solve the above-mentioned problems, as described below.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model provides a device for treating fly ash from incineration of garbage, comprising a main tank, one side of the main tank being connected to a water tank, a middle part of an upper end surface of the main tank being rotatably connected to a rotating shaft, the rotating shaft being located inside the main tank and fixedly connected to fan blades, one side of the upper surface of the main tank being provided with a driving assembly for driving the rotating shaft to rotate, the other side of the upper surface of the main tank being connected to an air outlet pipe extending into the water tank, a filter cylinder being detachably connected to the bottom opening of the main tank, and an air intake cavity being formed between the filter cylinder and the inner wall of the main tank, a disc being provided on the inner upper side of the filter cylinder, and bristles contacting the inner wall of the filter cylinder being provided on the circumferential surface of the disc, and a linkage structure for driving the disc to move up and down is provided at the lower end opening of the filter cylinder.

[0008] When using the above-mentioned fly ash treatment device for incinerated garbage, the main tank is installed above the incineration area, and the rotating shaft and fan blades are driven to rotate by the driving assembly. At this time, the fan blades draw the gas in the air intake cavity into the outlet pipe, and the fly ash below the main tank is sucked into the filter cylinder. After being filtered by the filter cylinder, the solid impurities are blocked on the inner wall of the filter cylinder, and the fine dust is left after the air flow passes through the water stored in the water tank, and the gas is discharged. When the air intake effect becomes worse, the disc is driven to move downward in the threaded cylinder through the linkage structure, so that the bristles on its surface brush off the solid impurities adhered to the surface of the filter cylinder for centralized collection.

[0009] Preferably, the driving assembly includes a motor fixedly mounted on the upper surface of the main tank, a gear one is fixedly connected to the output shaft of the motor, and a gear two meshing with the gear one is fixedly connected to the upper end of the rotating shaft.

[0010] Preferably, the diameter of gear one is greater than the diameter of gear two.

[0011] Preferably, the end of the air outlet pipe is located at the inner bottom of the water tank, and the lower part of the side wall of the water tank is connected to a drain pipe that can be opened and closed.

[0012] Preferably, a mounting ring is fixedly connected to the lower end of the filter cylinder, and the outer wall of the mounting ring is threadedly connected to the opening end of the main tank, and a sealing ring is provided at the lower end of the mounting ring.

[0013] Preferably, the linkage structure comprises a cross-shaped plate in the mounting ring, a slide rod hole is provided in the middle of the cross-shaped plate, a connecting rod is slidably connected in the slide rod hole, and the upper end of the connecting rod is fixedly connected to the disc.

[0015] Preferably, a mounting plate is fixedly connected to the middle portion of the side wall of the main tank.

[0016] The beneficial effects are:

[0017] The fan blades rotate to draw the gas in the air intake cavity into the air outlet pipe, and the fly ash under the main tank is sucked into the filter cylinder. Solid impurities are blocked on the inner wall of the filter cylinder, and fine dust is left behind after passing through the water stored in the water tank with the air flow, and the gas is discharged at the same time. When the air intake effect becomes worse, the disc is driven to move downward in the threaded cylinder, so that the bristles on its surface can brush off the solid impurities adhered to the surface of the filter cylinder. The cylindrical exhaust can make the air flow drive the fly ash to flow fully, so as to obtain a better air intake effect. At the same time, the preparation of the whole equipment is simple and convenient, which greatly reduces the preparation cost and improves the practicality. BRIEF DESCRIPTION OF THE DRAWINGS
