Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 6 As shown, a boiler ash classification and recovery processing device includes a base 1, a working frame 2 is provided on the upper part of the base 1, a feeding assembly 3 is provided on the top of the working frame 2, a filtering assembly 4 is provided at the lower part of the feeding assembly 3, and the filtering assembly 4 is arranged on the working frame 2. A screening assembly 5 is provided on one side of the working frame 2, and the screening assembly 5 is arranged at the lower part of the filtering assembly 4. An auxiliary assembly 6 is provided on the other side of the screening assembly 5, and the auxiliary assembly 6 is arranged at the lower part of the screening assembly 5. The screening assembly 5 and the auxiliary assembly 6 are both arranged at the upper part of the base 1. The working frame 2 is retractable. Before using the present invention, it is necessary to connect together according to the connection relationship of each component, and all electrical components in the present invention are externally connected to a power supply and a control switch to ensure the normal use of the present invention. The base 1 serves as the supporting structure of the entire device to ensure the stability and safety of the device. It is welded with high-strength steel and the surface is treated with anti-corrosion. The working frame 2 supports and connects each functional component. It is designed as a retractable structure, which is convenient for adjusting the height and width according to the processing requirements. The telescopic mechanism can be driven by hydraulic or electric drive to ensure easy and stable operation. High-quality steel and aluminum alloy materials are used to reduce weight while ensuring strength. The feeding group feeds the boiler ash into the device for preliminary treatment. The filtering component 4 performs preliminary filtering on the ash to remove large impurities and moisture. The screening component 5 further screens the filtered ash into particles of different sizes. The auxiliary component 6 collects the screened ash particles for subsequent treatment or storage.

[0025] Specifically, if Figure 1-Figure 6As shown, the filter assembly 4 described in this embodiment includes a filter filling bin 41, which is arranged at the lower part of the filling assembly, a filter channel 42 is arranged at the lower part of the filter filling bin 41, a support column 43 is arranged at the lower part of the filter channel 42, a support spring 44 is sleeved on the support column 43, and the filter channel 42 is connected to the side wall of the filter filling bin 41 through a connecting buckle 45, and a collection box 46 is arranged at the lower part of the filter channel 42. The filter filling bin 41 serves as a preliminary receiving and storage area for ash and slag, and ash and slag are filled into the filter channel 42 at the same time. It is designed as a closed or semi-closed structure with sufficient volume to accommodate a certain amount of ash and slag. It is made of corrosion-resistant and wear-resistant materials, such as stainless steel or alloy steel. The filter channel 42 filters the ash and slag to remove impurities and moisture therein. The filter channel 42 is designed as an inclined or vertical channel, and a filter screen is arranged inside. The filter screen is made of stainless steel, which is corrosion-resistant and wear-resistant. The filter channel 42 is connected to the side wall of the filter filling bin 41 through a connecting buckle 45 to ensure a firm and stable connection. The support column 43 supports the filter channel 42 to ensure its stability and filtering effect. The support column 43 is designed as an upright columnar structure with sufficient strength and rigidity. The support column 43 is made of high-strength steel and the surface is treated with anti-corrosion. The support spring 44 provides buffering and shock absorption for the filter channel 42 to reduce vibration and noise. The support spring 44 is sleeved on the support column 43 and connected to the lower part of the filter channel 42. The support spring 44 is made of a highly elastic and corrosion-resistant spring material. The collection box 46 collects the filtered ash particles for subsequent processing or storage. The collection box 46 is designed as a detachable box structure with sufficient volume and strength. The collection box 46 is made of wear-resistant and corrosion-resistant materials, such as stainless steel or alloy steel. The boiler ash is sent into the filter filling bin 41 through the feeding assembly 3. According to the processing requirements, the filling speed and the uniformity of the ash are adjusted. After the ash accumulates to a certain amount in the filter filling bin 41, it enters the filter channel 42 by gravity or vibration. The filter screen in the filter channel 42 filters the ash and removes the ash with a relatively small volume. The filtered ash particles fall into the collection box 46, and the other ash flows along the filter channel 42 to the screening component 5. When the ash particles in the collection box 46 accumulate to a certain amount, the filtering operation is stopped. The collection box 46 is disassembled from the lower part of the filter channel 42, and the ash particles are transported to a designated location for subsequent processing or storage.

[0026] Specifically, Figure 1-Figure 6As shown, the feeding assembly 3 described in this embodiment includes a feeding rack 31, on which a feeding conveyor belt 32 is provided, the angle between the working plane where the feeding conveyor belt 32 is located and the horizontal plane is 30°, and an anti-skid groove 33 is provided on the feeding conveyor belt 32, and the vertex of the feeding conveyor belt 32 is located at the upper part of the filter filling bin 41. The angle between the working plane where the feeding conveyor belt 32 is located and the horizontal plane is 30°. This angle is selected to balance the material conveying efficiency and the carrying capacity of the conveyor belt. The inclination angle of 30° can reduce the wear and energy consumption of the conveyor belt while ensuring the smooth conveying of the material. The feeding conveyor belt 32 is provided with an anti-skid groove 33 to increase the friction between the material and the conveyor belt to prevent the material from slipping or accumulating during the conveying process. The vertex of the feeding conveyor belt 32 is located at the upper part of the filter filling bin 41. This means that the material is fed into the filter filling bin 41 at the highest point of the conveyor belt, which is convenient for subsequent processing or processing. When the conveyor belt is started, the material is placed at the lower end of the conveyor belt and is conveyed upward with the movement of the conveyor belt. Since the conveyor belt has a 30° inclination angle and the anti-skid groove 33, the material can move stably on the conveyor belt without slipping or piling up. When the material reaches the top of the conveyor belt, it is sent to the filter filling bin 41 for subsequent processing.

[0027] Further, such as Figure 1-Figure 6As shown, the screening component 5 described in this embodiment includes a screening frame 51, which is arranged at the lower part of the filtering channel 42, and a screening net 52 is provided on the screening frame 51. A connecting channel 53 is provided at the lower part of the screening net 52, and the connecting channel 53 is connected to the auxiliary component 6. The screening net 52 is magnetically slidably connected to the screening frame 51, and a placing table 54 is provided at the lower part of the screening frame 51. A screening motor 55 is provided on the placing table 54, and the screening motor 55 is connected to a connecting piece 56, and the connecting piece 56 is connected to the screening net 52. A discharge port 57 is provided on the side of the screening frame 51. The supporting column 43 is retractable. The height of the end of the filtering channel 42 close to the screening component 5 is lower than the height of the end of the filtering channel 42 away from the screening component 5. The auxiliary component 6 includes an auxiliary frame 61, on which an auxiliary net 62 is provided, the auxiliary net 62 is magnetically slidably connected to the auxiliary frame 61, the auxiliary net 62 is connected to the connecting channel 53, the end of the auxiliary net 62 away from the screening component 5 is provided with a collecting port 63, the lower part of the other end of the auxiliary net 62 is provided with an auxiliary table 64, the auxiliary table 64 is provided with an auxiliary motor 65, the auxiliary motor 65 is connected to a connecting member 56, and the connecting member 56 is connected to the auxiliary net 62. The connecting member 56 includes an output shaft 561, the output shaft 561 is connected to a C-shaped connecting rod 562, and the protruding part of the C-shaped connecting rod 562 is connected to the screening net 52 or the auxiliary net 62 through a connecting plate 563. The filtering channel 42 is magnetically slidably connected to the filtering filling bin 41. The support column 43 supports the screening component 5 and the filtering channel 42 to ensure their stability and height adjustment. The support column 43 is a retractable structure, and the position of the screening component 5 and the filtering channel 42 can be adjusted by adjusting the height of the support column 43. The filter channel 42 transports the material from the filter filling bin 41 to the screening component 5. It is an inclined channel, and the height of the end close to the screening component 5 is lower than the end away from the screening component 5, which facilitates the smooth flow of the material. Start the screening motor 55 and the auxiliary motor 65 to provide vibration power for the screening net 52 and the auxiliary net 62. The material enters the filter channel 42 from the filter filling bin 41, and flows into the screening component 5 after preliminary filtration. The material is screened on the screening net 52 and classified according to the particle size. The screened material enters the auxiliary component 6 through the connecting channel 53. The material that meets the requirements is collected on the auxiliary net 62 and discharged through the collection port 63. The waste material is discharged through the discharge port 57. According to the needs, adjust the height of the support column 43 and adjust the position of the screening component 5 and the filter channel 42. Clean the screening net 52, the auxiliary net 62 and the connecting channel 53 and other components regularly to ensure the normal operation of the equipment and extend the service life.
