Description

Technical Field

[0001] This utility model relates to the field of crushed stone washing technology, and in particular to a water-washed crushed stone tailings recycling device. Background Technology

[0002] Because the surface soil layer cannot be completely removed during the mining of crushed stone, soil will be carried into the crushed stone. The mud powder and stone powder generated during crushing will affect the performance of the crushed stone in concrete. In order to solve the problem of mud powder and stone powder, crushed stone production enterprises need to wash the stone with water before leaving the factory or before concrete enterprises use it. The water washing is generally carried out by spraying water with a vibrating screen. This method not only screens out stone powder and mud powder.

[0003] Chinese patent CN204735331U discloses a water-washed crushed stone tailings recycling device, including a confluence hopper, a hopper, and a spiral tube. One end of the confluence hopper is connected to a vibrating screen to collect the residue after screening, and the other end is connected to the hopper. The spiral tube includes a tube body and a screw installed inside the tube body. The tube body is inclined, with the bottom of the hopper connected to the lower part of the tube body. A crushed stone outlet is located at the higher part of the tube body. A motor is installed on the outside of the tube body, driving the screw to rotate and conveying the crushed stone from the lower part to the higher part. A drain outlet is opened at the top of the hopper. This novel water-washed crushed stone tailings recycling device can mix mud powder and stone powder in water and allow them to flow out through the drain outlet. This ensures the extraction of mud powder and stone powder, while also ensuring the recycling and reuse of small particles in the crushed stone, resulting in a more reasonable gradation of the crushed stone and reducing the cost of waste disposal.

[0004] Existing washing and recycling equipment for crushed stone tailings is inconvenient for screening the crushed stone tailings. Tailings of mixed sizes are directly fed into the washing process. Large pieces of tailings not only occupy effective washing space and consume additional water and power, but may also leave surface impurities due to insufficient washing time. Small pieces of tailings may suffer material loss due to over-washing. At the same time, the mixed particle sizes will interfere with the dewatering and recycling processes after washing, ultimately resulting in poor overall washing uniformity of the crushed stone tailings and incomplete removal of impurities, leading to a reduction in the recycling rate of crushed stone tailings.

This allows tailings of different particle sizes to be processed under appropriate washing parameters, ensuring thorough removal of surface impurities from large tailings while preventing damage to small tailings due to over-washing. This significantly improves the overall washing quality and enhances the effectiveness of the crushed stone tailings recycling device. Attached Figure Description

[0032] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0033] Example 1

[0034] like Figure 1 - Figure 5 As shown, the present invention proposes a water-washed crushed stone tailings recycling device, comprising: a feeding assembly, a dispersing assembly, a conveying assembly, and a water spraying assembly; the feeding assembly includes a feeding box 1, a screening plate 101, and an inclined plate 102; the screening plate 101 and the inclined plate 102 are connected inside the feeding box 1, and the inclined plate 102 is located below the screening plate 101; the dispersing assembly is connected to the feeding box 1; two conveying assemblies are provided, and the two conveying assemblies are respectively connected to both sides of the feeding box 1; two water spraying assemblies are provided, and the two water spraying assemblies and the two conveying assemblies are connected in a one-to-one correspondence. The tilt angle of the screening plate 101 and the inclined plate 102 is set to ensure that large-diameter tailings that do not pass through the filter holes can slide down the plate and avoid the accumulation of small-diameter tailings. The feeding component is for tailings screening. The dispersing component is directly assembled on the feeding component to break up tailings agglomeration and improve the screening effect. The conveying components are respectively connected to both sides of the feeding component to receive tailings of different sizes after screening. The water spraying component corresponds to the conveying component to provide water washing for the tailings during the conveying process, so that the recycling device can wash and recycle the crushed stone tailings.

[0035] To further explain, both sides of the feed box 1 are provided with guide ports a and b. The screening plate 101 is inclined towards the guide port a, and the inclined plate 102 is inclined towards the guide port b. The screening plate 101 is provided with filter holes a. The outer walls of the feed box 1 are respectively connected to the support base 103 and the slide rail 104. The feed box 1 is connected to one side of the guide plate 6. The guide plate 6 is connected to the vertical plates 7 on both sides. The guide plate 6 is located close to the guide port b. The lower end of the guide plate 6 is connected to the guide plate 301 on one side. The guide plate 6 and the vertical plates 7 welded on both sides are designed to prevent the tail material from leaking out. The lower end of the guide plate 6 is connected to the guide plate 301 of the conveying component near the feed port b, which ensures that the small crushed stone enters the conveying component smoothly for washing. A vibrating table is connected below the feed box 1. The vibrating table is built using existing mature technology. Its specific composition and working principle have been standardized in the industry, so there is no need to elaborate on the details here. The vibration frequency is adjustable, and the vibration improves the screening effect of the crushed stone tail material in the feed box 1.

[0036] Further explanation: The dispersing assembly includes a dispersing plate 2, a support bracket 201, a telescopic cylinder 202, a moving block 203, and a guide frame 204; the dispersing plate 2 is connected to the support bracket 201 on both sides, the drive end of the telescopic cylinder 202 is connected to one side of the support bracket 201, the moving block 203 is connected to the support bracket 201 on the other side, the guide frame 204 is connected to one side of the feed box 1, the inner wall of the guide frame 204 is provided with a moving rail, and the moving block 203 is slidably connected in the moving rail; the telescopic cylinder 202 is connected to the support base 103, and a slider is slidably connected in the slide rail 104, and the slider is connected to the support bracket 201 near the telescopic cylinder 202. When the telescopic cylinder 202 extends and retracts, it drives the support bracket 201 on one side to move back and forth along the slide rail 104. At the same time, the support bracket 201 on the other side moves synchronously along the moving rail of the guide frame 204 via the moving block 203. Finally, it drives the dispersing plate 2 to move horizontally back and forth on the feed box 1, breaking up the crushed stone tailings and letting them fall into the feed box 1, thus avoiding screening blockage caused by agglomeration.

[0037] Example 2

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, the present invention proposes a water-washed crushed stone tailings recycling device. Based on the above embodiments, this embodiment also details the specific components of the conveying component and the water spraying component, as well as their coordination.

[0039] Further explanation: The two conveying components include a conveying shell 3, a guide plate 301, a discharge port 302, a spiral conveyor a 303, a servo motor 304, a gear a 305, a gear b 306, and a spiral conveyor b 307, respectively. The feed end of the conveying shell 3 is connected to the guide plate 301, and the discharge port 302 is connected below the feed end of the conveying shell 3. The spiral conveyor a 303 and the spiral conveyor b 307 are connected inside the conveying shell 3. The servo motor 304 is connected to one side of the outer wall of the conveying shell 3. The output shaft of the servo motor 304 is connected to the spiral conveyor a 303. The outer wall of the output shaft is connected to the gear a 305. The gear a 305 and the gear b 306 are meshed. The gear b 306 is connected to the shaft, and the shaft is connected to the spiral conveyor b 307. A water outlet is provided at the end of the conveying shell 3 near the guide plate 301. A collection box 5 is connected below the water outlet. Support rods are connected to both sides of the inner wall of the collection box 5. A baffle 501 is supported and connected above the support rods. Spiral conveyor plates a303 and b307 are rotatably connected to the inner wall of the conveyor housing 3 via shafts. A servo motor 304 is fixed to one side of the outer wall of the conveyor housing 3. The motor output shaft passes through the side wall of the conveyor housing 3, and one end is fixedly connected to the shaft of spiral conveyor plate a303, with gear a305 fixedly sleeved thereon. A fixed sleeve is provided on the shaft of spiral conveyor plate b307, and gear b306 is connected to the fixed sleeve on the shaft of spiral conveyor plate b307. Gears a305 and b306 are meshed. When the servo motor 304 starts... Through the meshing transmission of gears a305 and b306, the screw conveyor plates a303 and b307 are driven to rotate synchronously in opposite directions, avoiding local accumulation and pushing the tail material from the feed end of the conveyor shell 3 to the discharge port 302. The screw conveyor plates are made of wear-resistant and impact-resistant high-chromium alloy material, which can effectively resist the scouring and wear of the crushed stone tail material. The welding joint between the screw conveyor plate and the shaft adopts double-sided bevel welding, and a reinforcing rib plate is added to the outside of the weld. The material of the reinforcing rib plate is the same as that of the screw conveyor plate to prevent the weld from cracking or falling off due to material impact.

[0040] To further explain, the two water spray components each include a mounting bracket 4, a support block 401, a water tank 402, a connecting pipe 403, an interface 404, and a spray head 405. The mounting bracket 4 is connected to the conveying shell 3 and is connected to the support block 401. The water tank 402 is connected below the support block 401. The water tank 402 is connected to the connecting pipe 403. The upper end of the connecting pipe 403 passes through the support block 401, the mounting bracket 4, and the interface 404. The interface 404 is located on the mounting bracket 4. Several spray heads 405 are connected below the water tank 402, and the water outlet of the spray head 405 faces into the conveying shell 3. The mounting bracket 4 has a U-shaped structure, with both ends connected to the outer walls of the conveying shell 3 via high-strength flanges. The interface 404 can be connected to an external water source, such as a water pump or water tank, to ensure a continuous water supply in the water tank 402. The spray head 405 is a high-pressure atomizing nozzle, or a direct spray nozzle can be selected according to the particle size of the tailings. Large tailings are sprayed with high-pressure direct spray, while small tailings are sprayed with atomized spray to prevent the tailings from being scattered. The water outlet of all spray heads 405 is perpendicular to the tailings conveying path inside the conveying shell 3 to ensure that the water flow can fully cover the tailings in the conveying process and achieve the purpose of washing away the mud, dust and impurities on the surface.

[0041] The working principle of this utility model is as follows: Before use, the device needs to be pre-treated and inspected: confirm that the telescopic cylinder 202 of the dispersing component, the servo motor 304 of the conveying component, and the water supply interface 404 of the water spraying component are all in normal standby mode. Simultaneously, clean the residual fine material and wastewater in the collection box 5, ensuring that the filter holes b of the baffle 501 are not blocked. Add the crushed stone tailings to the dispersing plate 2 in small amounts multiple times. This method of adding the tailings in small amounts multiple times avoids the tailings accumulating instantly and causing the dispersing plate 2 to jam. It also prevents the filter holes of the screening plate 101 in the feed box 1 from becoming blocked due to excessive load, and avoids damage to the conveying component. The crushed stone tailings enter through the dispersing plate 2... The material is dispersed into the feed box 1. The dispersing plate 2 has through holes to allow tailings of varying sizes to fall into the feed box 1. When the vibrating table at the bottom of the feed box 1 is activated, the tailings first fall onto the screening plate 101. The filter holes a of the screening plate 101 block the large-diameter gravel, while the small-diameter tailings fall through the filter holes onto the inclined plate 102. The inclined ends of the screening plate 101 and the inclined plate 102 face the guide port a and guide port b, respectively. Guide port a is connected to the guide plate 301 of the adjacent conveying component, and guide port b is connected to the adjacent conveying component through the guide plate 6. This allows the large-diameter tailings that cannot pass through the filter holes a of the screening plate 101 to slide along the inclined screening plate 101 towards the guide port b. The material enters the feed box 1 through the feed inlet a, then falls through the feed plate 301 of the corresponding conveying component, and finally enters the conveying shell 3 of the conveying component. Small-diameter tailings that pass through the filter holes a of the screening plate 101 fall onto the inclined plate 102 inside the feed box 1, slide along the inclined plate 102 to the feed inlet b, and then through the guide plate 6 and the vertical plate 7 to prevent side leakage into the feed plate 301 of the corresponding conveying component, and enter the conveying shell 3 of the conveying component. Different sizes of crushed stone tailings enter the conveying component respectively. During the conveying process, the water spray component is used to wash the crushed stone tailings. The wastewater generated from the washing flows out through the outlet of the conveying shell 3 and is first filtered through the outlet. The wastewater undergoes initial filtration and then flows into the collection box 5 below. When the wastewater passes through the baffle 501 inside the collection box 5, the smallest particles are intercepted by the filter holes b and can be recycled separately. The filtered wastewater enters the external water recycling equipment through the bottom pipe of the collection box 5 to achieve water resource recycling. The washed crushed stone tailings are conveyed to the discharge port 302 by the conveying component. A crushed stone tailings conveying component, such as a conveyor belt, is placed at the lower end of the discharge port 302 to transfer the washed tailings to the next processing device, such as a drying, grading and storage device, thus completing the washing and recycling of the crushed stone tailings. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
