TECHNICAL FIELD

[0001] The present application relates to the technical field of fly ash treatment, and particularly relates to a fly ash filtering device with a cleaning function for fly ash treatment. BACKGROUND

[0002] Fly ash is a kind of tiny ash particles discharged in the process of fuel combustion, and belongs to hazardous waste. A large amount of fly ash is generated in the process of waste incineration. The fly ash may contain heavy metals and other harmful substances. If the fly ash is not controlled or treated, it will cause air pollution, and will clog up river channels when entering water bodies. Some chemical substances may cause harm to organisms and human bodies. Therefore, it is very important to properly treat the fly ash.

[0003] In the prior art, the method for treating fly ash is generally to collect the fly ash through a collecting device. However, this method has some problems. First, the collected fly ash is still in a state of flying in the collecting device, which increases the health risk of the workers when they treat the fly ash later. Second, the content of chloride salt in the fly ash is high. If the fly ash is not pretreated, the resource utilization of the fly ash may be affected, and the risk of heavy metal leaching may be increased. SUMMARY

[0009] In the collecting mechanism, the mechanism is used for collecting the surrounding fly ash so as to concentrate it in a certain place, facilitating the operation of the subsequent mechanism.

[0014] In the water injection mechanism, the mechanism injects water to the workbench by adjusting the angle of the water outlet nozzle, so that the water falls on the workbench above and the fly ash and water can be mixed. The workbench is smaller than the area of the collection cavity, and the workbench is also engaged with the second partition, so that the fly ash collected in the collection cavity mostly falls on the workbench after entering. The first drive motor drives the rotating rod to rotate, so that the driven block moves along the direction of the rotating rod. The rotating motor is tightly connected to the bottom of the driven block. The rotating motor output end is tightly connected to the water injection pipeline through the connecting rod. After the device is started, the water in the water storage tank flows out through the water outlet nozzle, first watering the workbench so that the workbench can better absorb the fly ash. Then the fly ash enters the upper half of the collection cavity and falls on the workbench. Then the water outlet nozzle continues to flow water to the workbench, so that the fly ash can be fully mixed with water. After the fly ash stops entering the collection cavity, the first drive motor starts, moving the rotating motor, and then the rotating motor starts to rotate with the water injection pipeline to adjust the angle of the water outlet. The fly ash on the edge of the workbench can be washed to the middle area. At the same time, the workbench is provided with a water guide, and the water guide is also covered with a filter screen. Some excess water can be filtered out during the mixing of water and fly ash. The water will flow along the water guide to the edge of the lower half of the collection cavity, and the bottom of the lower half is inclined, so that the filtered water will flow along the inclined angle and flow out of the backflow pipe. Some impurities exist in the water, which is purified and returned to the water storage tank for reuse. After the subsequent filtering and drying operations are completed, the second drive motor is started to rotate the rotating shaft, and the rotating shaft is tightly connected with the two workbenches.

The fly ash outlet is arranged on the wall of the collection tank away from the collection pipe. The conveying direction of the conveyor belt faces the fly ash outlet.

[0016] In the separating mechanism, the mechanism is used for solid-liquid separation of the mixture of fly ash and water, so that most of the useless water is filtered out, only the water that can keep the fly ash solid is left, and then it is dried, so that the internal moisture content is very small, and the fly ash after drying is a dry solid, which is convenient for subsequent resource utilization. After the fly ash flows into the workbench, the hydraulic cylinder is driven to start, and the arc-shaped pressing plate is pressed down, so that the water in the fly ash is squeezed out and flows to the edge of the lower half of the collection cavity through the waterway. After that, the hydraulic cylinder is lifted, the arc-shaped pressing plate is away from the workbench, and then the fan is started to dry the filtered fly ash. After drying, the rotating shaft rotates 180°, and the workbench in the upper half of the collection cavity is transferred to the lower half, and the workbench in the lower half is transferred to the upper half. The dry fly ash falls into the conveyor belt after the workbench is transferred, and the fly ash is conveyed out of the fly ash outlet through the conveyor belt. The workbench in the upper half continues to mix and separate fly ash and water.

[0018] In the cleaning mechanism, the mechanism is used for cleaning the wall surface of the upper half of the collection cavity. When the fly ash enters the upper half of the collection cavity, some of the fly ash will stick to the wall surface. The fly ash on the wall surface is scraped off by the cleaning scraper and the pushing hydraulic cylinder, so that the fly ash reaches the junction between the second partition plate and the wall surface.

[0042] In the separating mechanism 3, the mechanism is used for solid-liquid separation of the mixture of fly ash and water, so that most of the useless water is filtered out, only the water that can keep the fly ash solid is left, and then drying is performed, so that the water content in the fly ash is very small. After drying, the fly ash is a dry solid, which is convenient for subsequent resource utilization. After the fly ash flows to the middle of the workbench 23, the driving hydraulic cylinder 31 is started, the arc-shaped pressing plate 32 is pressed down, so that the water in the fly ash is squeezed out and flows to the edge of the lower half cavity of the collecting cavity 131 through the water channel. Then the driving hydraulic cylinder 31 is lifted, the arc-shaped pressing plate 32 is away from the workbench 23, then the fan 34 is started to dry the fly ash after filtering water. After drying, the rotating shaft 24 rotates by 180°, the workbench 23 arranged in the upper half cavity of the collecting cavity 131 is transferred to the lower half cavity, the workbench 23 in the lower half cavity is transferred to the upper half cavity, and the dried fly ash falls into the conveyor belt 33 after the workbench 23 is transferred downward, and the fly ash is conveyed out of the fly ash outlet 133 through the conveyor belt 33. The workbench 23 located in the upper half cavity continues to mix and separate the fly ash and water.
