Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of coal ash processing technology, and more specifically, to a wastewater treatment system for coal ash separation. Background Technology

[0002] In coal-fired power plants or coal chemical enterprises, the treatment of coal ash water is a crucial step. Currently, the coal ash water treatment equipment in these enterprises in China is usually quite complex, consisting of numerous devices such as a pre-lift pump, mixing reactor, sedimentation tank, intermediate tank, lift pump, and sand filter. These devices are connected by pipelines, and the water levels before and after the pumps need to be controlled. This treatment method has many drawbacks, such as numerous devices, complex pipelines, difficult management, large workload, and high operating costs.

[0003] While some existing coal ash water treatment devices possess multiple functions such as mixing, sedimentation, and filtration, they may suffer from problems such as unreasonable structural design, low treatment efficiency, or inability to achieve efficient and automated processing when separating coal ash and wastewater. In some systems, there may be no feed processing components specifically designed for the characteristics of coal ash, making it impossible to effectively pre-treat the coal ash water entering the system. In the filtration stage, the filtration methods may be relatively traditional, making cleaning inconvenient and resulting in poor filtration effects or the need for frequent shutdowns for cleaning.

[0004] Therefore, there is a need for a simple, efficient and practical wastewater treatment system for coal ash separation that can optimize the feeding process, improve the convenience and effectiveness of filtration and cleaning, thereby better achieving the separation of coal ash and wastewater, reducing treatment costs, improving treatment efficiency and water quality, and meeting the actual needs of relevant enterprises in coal ash water treatment.

[0035] like Figures 1-4 As shown, it illustrates a wastewater treatment system for coal ash separation according to this disclosure, comprising:

[0036] Processing box 1, with a feed hood 2 installed at the top of processing box 1;

[0037] Feed processing component 3 is installed inside processing box 1;

[0038] Filter cleaning component 4 is located on the upper surface of the processing box 1;

[0040] The filter cleaning assembly 4 includes a cleaning port 4-5, which is located on the upper surface of the processing box 1. A filter plate 4-6 is provided on the upper surface of the inclined plate 3-2. The number of filter plates 4-6 is several, and multiple filter plates 4-6 are equidistantly arranged on the upper surface of the inclined plate 3-2.

[0041] In some examples, the feed hood 2 is installed on the upper end of the treatment box 1, and the feed hood 2 is tightly connected to the feed port 3-1 on the treatment box 1 to prevent wastewater leakage during the feeding process. An inclined plate 3-2 is installed inside the treatment box 1 and its position is fixed. A relief plate 3-3 is installed on the upper end face of the inclined plate 3-2. At the same time, an interception plate 3-4 is installed on the inner side wall of the treatment box 1, and a relief groove 3-5 is opened on the interception plate 3-4. A sealing plate 3-6 is installed on the lower end face of the inclined plate 3-2. The drive shaft 3-7 passes through the sealing plate 3-6, and the drive shaft 3-7 and the sealing plate 3-6 are movably connected by a bearing.

[0042] A cleaning port 4-5 is opened on the upper surface of the treatment box 1, and several filter plates 4-6 are installed at equal intervals on the upper surface of the inclined plate 3-2.

[0043] like Figures 1-4 As shown in the figure, this embodiment proposes that the inclined plate 3-2 is provided with an output motor 3-9 inside, the output end of the output motor 3-9 is fixedly connected to the drive shaft 3-7, and the drive shaft 3-7 is movably connected to the sealing plate 3-6 through a bearing.

[0044] In some examples, an output motor 3-9 is installed inside the inclined plate 3-2, and the output end of the output motor 3-9 is fixedly connected to the drive shaft 3-7.

[0045] For example, such as Figure 2As shown, the upper end face of the processing box 1 is provided with a mounting block 4-1, the inside of the mounting block 4-1 is provided with a flip shaft 4-2, and a sealing buckle cover 4-3 is fitted on the flip shaft 4-2. The sealing buckle cover 4-3 is fastened to the cleaning port 4-5.

[0046] In some examples, mounting block 4-1 is installed on the upper surface of processing box 1, flip shaft 4-2 is installed inside mounting block 4-1, sealing cover 4-3 is fitted onto flip shaft 4-2, and sealing cover 4-3 is fastened onto cleaning port 4-5.

[0047] For example, such as Figure 4 As shown, an annular gasket 4-4 is provided on the lower end face of the sealing cover 4-3, and the annular gasket 4-4 is located at the edge of the cleaning port 4-5.

[0048] In some examples, an annular gasket 4-4 is installed on the lower end face of the sealing cap 4-3, positioned at the edge of the cleaning port 4-5, to enhance the sealing effect.

[0049] For example, such as Figure 3 As shown, a rotating sleeve 5 is provided at the end of the drive shaft 3-7, and a stirring plate 3-8 is provided on the rotating sleeve 5. The rotating sleeve 5 and the drive shaft 3-7 are fixedly fitted together.

[0050] In some examples, a rotating sleeve 5 is fixed at the end of the drive shaft 3-7, and a stirring blade 3-8 is installed on the rotating sleeve 5, ensuring that the stirring blade 3-8 is located between the relief plate 3-3 and the relief groove 3-5.

[0051] For example, such as Figure 2 As shown, a motor frame 6 is provided on the lower end face of the inclined plate 3-2. The motor frame 6 is fixedly connected to the output motor 3-9, and the output end of the output motor 3-9 passes through the motor frame 6.

[0052] In some examples, a motor frame 6 is mounted on the lower end face of the inclined plate 3-2, and the motor frame 6 is fixed to the output motor 3-9, allowing the output end of the output motor 3-9 to pass through the motor frame 6.

[0053] For example, such as Figure 2 As shown, the side wall of the treatment box 1 is provided with a liquid outlet 7 and a cleaning port 8. The liquid outlet 7 is located on the lower end face of the sealing plate 3-6 and the lower end face of the interception plate 3-4. The cleaning port 8 is located on the upper end face of the interception plate 3-4. The lower end face of the treatment box 1 is provided with a supporting foot 9.

[0054] In some examples, a liquid outlet 7 and a cleaning port 8 are provided at corresponding positions on the side wall of the treatment tank 1. The liquid outlet 7 is located on the lower end face of the sealing plate 3-6 and the lower end face of the interceptor plate 3-4, and the cleaning port 4-5 is located on the upper end face of the interceptor plate 3-4.

[0055] For example, such as Figure 2As shown, a valve 10 is installed between the liquid outlet 7 and the cleaning port 8, and the valve 10 is controlled by a motor.

[0056] In some examples, a valve 10 is installed between the liquid outlet 7 and the cleaning outlet 8, and a motor for controlling the valve 10 is connected.

[0057] During use, connect the power supply to the output motor 3-9 and the control valve 10 motor to ensure the equipment is in an operable state. Open the outlet valve 10 and adjust it to an appropriate opening degree so that the purified water can flow out smoothly. Slowly inject the coal ash wastewater to be treated into the treatment tank 1 through the feed hood 2. During the feeding process, pay close attention to the feeding speed to avoid wastewater overflow due to excessive feeding. Start the output motor 3-9 in the inclined plate 3-2 and adjust the motor speed appropriately according to the nature of the wastewater and the treatment requirements. The stirring plate 3-8 starts to rotate under the drive shaft 3-7 to stir the wastewater, so that the coal ash and water are fully mixed and promote preliminary separation. The stirred wastewater gradually flows to the filter plate 4-6 on the inclined plate 3-2. The filter plate 4-6 intercepts the coal ash, and the preliminarily purified water continues to flow along the inclined plate 3-2. -2 flows downwards. During this process, the operator needs to regularly observe the working condition of the filter plate 4-6. If the filtration speed is found to decrease significantly, it may be due to blockage of the filter plate 4-6, which should be cleaned in time. The purified water flows out from the outlet 7. The outlet speed of the outlet 7 can be precisely adjusted according to actual needs by controlling the motor of valve 10. As the treatment process proceeds, coal ash will gradually accumulate above the interception plate 3-4. When it accumulates to a certain extent, open the cleaning port 8 valve 10 to discharge the intercepted coal ash and other impurities from the treatment box 1. Regularly open the sealing cover 4-3 to clean the filter plate 4-6. High-pressure water gun washing or brush washing can be used to remove the coal ash impurities intercepted on the filter plate 4-6 and restore the filtration performance of the filter plate 4-6. After cleaning, close the sealing cover 4-3 in time to ensure good sealing.

[0058] If a leak is detected during operation, feeding and motor operation should be stopped immediately, and the leak point should be located quickly. For minor leaks, they can be dealt with by tightening the connections or replacing the gaskets. For serious leaks, the wastewater in treatment tank 1 should be emptied in time, and the damaged parts should be repaired or replaced.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
