Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral washing and beneficiation technology, specifically to an automatic washing and beneficiation machine. Background Art
[0002] Mineral washing is a process that removes impurities from raw ore and improves its grade through physical or chemical methods. This process typically involves mixing the raw ore with water or other liquids and then utilizing physical properties such as differences in density, particle size, magnetic properties, and electrical properties.
[0003] Washing and beneficiation equipment separates ore from impurities. It removes impurities from the ore through the flow of water and friction of the material, thereby improving the grade of the ore. It also separates concentrate and tailings by screening the ore based on density differences. The purpose is to improve the purity and grade of the ore for subsequent processing, smelting or other uses.
[0004] In the process of realizing this utility model, the inventor discovered the following problems with the existing technology: 1. Currently, many washing and screening machines usually use hydraulic and gravitational fields to separate ores. By means of water flow and vibration, the useful minerals and useless impurities in the ore are separated into layers, thereby separating concentrate and tailings. Although the purpose of washing is effectively achieved at the same time as screening, a large amount of water is required, which will undoubtedly lead to the waste of water resources; 2. The current washing and screening machines are too large and inconvenient to use in some small and medium-sized ore processing centers. Utility Model Content

A steel brush head is rotatably connected to the bottom of the cross beam, and the top of the steel brush head passes through the shaft of the synchronous pulley via a shaft rod.
[0010] The tailings frame includes an electric telescopic rod and a tailings discharge plate. One end of the electric telescopic rod is connected to both sides of the tailings discharge plate by bolts, and the other end of the electric telescopic rod is connected to the surface of the rear support by bolts. One end of the tailings discharge plate is rotatably connected to one end of the tailings frame.
[0011] More preferably, the front support, middle support and rear support are welded together as one piece, and the conveyor is rotatably connected to the inside of the front support, with one-third of the total length of the conveyor located inside the feed box, while the material collection chamber is located in the cavity between the front support and one side of the feed box.
[0012] More preferably, the feed box and the sorting box are inclined, and the lowest point of the feed box is located above the screen plate, and the lowest point of the screen plate is located above the tailings frame. At the same time, the nozzle is located above the screen plate, and the bottom of the sorting box has a through hole located directly above the collection tank.
[0013] More preferably, the surface of the rear support is provided with a servo motor welded to the bottom shaft of the lead screw, and the lead screws are connected by a belt.

Moreover, this equipment occupies less space than general washing and screening equipment, and completes the washing and screening of minerals through a stepped, layer-by-layer screening process.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: an automatic washing and screening machine, including a front support 1, with a feed box 2 and a transmission table 3 respectively opened on the inner wall of the front support 1, a middle support 4 welded to one side of the front support 1, a sorting box 5 installed inside the middle support 4, the transmission table 3 located on one side of the feed box 2, the sorting box 5 located on the other side of the feed box 2, a rear support 6 welded to one side of the middle support 4, a lead screw 7 rotatably connected inside the rear support 6, a concentrate frame 8 welded to the lead screw 7 through a nut, a tailings frame 9 opened below the concentrate frame 8, one end of the tailings frame 9 rotatably connected to the inner wall of the rear support 6, and a hydraulic column 10 welded to the other end of the bottom of the tailings frame 9, the bottom of the hydraulic column 10 being at the same horizontal position as the rear support 6.
[0027] The inner wall of the feed box 2 is provided with a spray port 201 and an air inlet 202 through both ends. A fan 203 is provided at one end of the air inlet 202. The fan 203 is bolted to the inner wall of the front bracket 1. The fan 203 is connected to the air compressor 204 through a pipe. A material collection chamber 205 is provided on one side of the spray port 201.
[0028] The middle support 4 is provided with a first buffer spring 401 and a second buffer spring 402. A collection trough 403 is slidably connected to one side of the middle support 4. A pipe frame 404 is welded to the outer wall of the middle support 4. A water supply pipe connected to several nozzles 405 is installed inside the pipe frame 404 by bolts.
[0029] The inner wall of the sorting box 5 is welded with a screen plate 501. The sorting box 5 is welded to the inner wall of the middle support 4 through the first buffer spring 401 and the second buffer spring 402. A vibration motor 502 is provided at the bottom of the sorting box 5.
[0030] A connecting frame 801 is welded to the surface of the concentrate frame 8, and a cross beam frame 802 is welded between the connecting frames 801. A steel brush head 803 is rotatably connected to the bottom of the cross beam frame 802, and the top of the steel brush head 803 is connected to the axis of the synchronous pulley 804 through a shaft.
[0031] The tailings frame 9 includes an electric telescopic rod 901 and a tailings discharge plate 902. One end of the electric telescopic rod 901 is connected to both sides of the tailings discharge plate 902 by bolts, and the other end of the electric telescopic rod 901 is connected to the surface of the rear support 6 by bolts. One end of the tailings discharge plate 902 is rotatably connected to one end of the tailings frame 9.
[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the front support 1, middle support 4, and rear support 6 are welded together as one unit, and the conveyor platform 3 is rotatably connected to the inside of the front support 1. One-third of the total length of the conveyor platform 3 is located inside the feed box 2, while the collection chamber 205 is located in the cavity between the front support 1 and the feed box 2 on one side. The principle of the conveyor platform 3 is based on mechanical motion and the operation of the conveyor belt to move materials from one location to another. The inside of the conveyor platform 3 is supported by several rollers, and each set of rollers is equipped with pulleys at both ends. The rollers and pulleys are covered with a conveyor belt. Minerals can be conveyed to the inside of the feed box 2 via the conveyor platform 3. The feed box 2 is an inclined surface, and the materials will converge downwards under gravity as they are continuously conveyed. Current washing and screening machines usually use water flow to wash and screen minerals as they enter the equipment, but... When minerals first enter the equipment, they are often mixed with sand and soil impurities. Washing these substances together not only fails to improve the screening effect but also increases water consumption. By installing a blower 203 on the surface of the front support 1, and using an air compressor 204 (model V-0.36 / 12.5), the principle is to increase the pressure and energy of the air by compressing it, providing a high-pressure gas flow. This gas is then transported through pipelines to the blower 203 to separate the ore from impurities during the screening process. This process treats the minerals that first enter the feed box 2, blowing the lighter impurities such as sand and soil mixed inside into the collection chamber 205 through the high-pressure airflow. This provides the basic conditions for subsequent screening and cleaning of raw materials, effectively avoiding the large amount of water wasted due to the treatment of unnecessary impurities, thus saving water resources.
[0033] In this embodiment, as Figure 2 and Figure 3As shown, the feed box 2 and the sorting box 5 are inclined, with the lowest point of the feed box 2 located above the screen plate 501, and the lowest point of the screen plate 501 located above the tailings frame 9. Simultaneously, the nozzle 405 is located above the screen plate 501. A through hole is provided at the bottom of the sorting box 5, directly above the collection trough 403. The vibration motor 502 (model YZS-2.5-2) generates centrifugal force through its output end, causing the internal eccentric block to vibrate. Due to the asymmetry of the eccentric block, the vibration motor 502 vibrates, which in turn causes the sorting box 5 to vibrate. Since the sorting box 5 is fixed by the first buffer spring 401 and the second buffer spring 402, its elasticity can dampen and absorb the vibration of the sorting box 5. The vibration of the screen box allows it to generate appropriate vibration amplitude and frequency during the vibration process, and uses this vibration amplitude to perform secondary screening of the internal raw materials. Since minerals are different from sand and gravel and have a certain weight, the stability of the sorting box 5 during movement is increased by adding second buffer springs 402 on both sides. The material secondary screened on the surface of the sorting box 5 can be cleaned by the top nozzle 405. During the screening process, the surface of the minerals is washed to remove the clay that the airflow cannot remove from the surface of the minerals. Minerals and impurities that do not meet the specifications will flow into the bottom of the sorting box 5 below through the surface of the screen plate 501, and fall into the collection tank 403 through the through hole at the bottom of the sorting box 5 in a progressive manner during continuous vibration.
[0034] In this embodiment, as Figure 4 As shown, a servo motor welded to the bottom shaft of the lead screw 7 is provided on the surface of the rear support 6, and the lead screws 7 are connected by a belt. The concentrate frame 8 forms a lifting structure inside the tailings frame 9 through the lead screw 7. At the same time, a concentrate discharge plate 805 is rotatably connected to one side of the concentrate frame 8. Due to the inclined structure of the sorting box 5, the minerals that have been screened by the sorting box 5 can fall to the lowest point in a progressive manner through vibration amplitude. The concentrate frame 8 and the tailings frame 9 are the final positions for processing and screening minerals. The transmission structure of the lead screw 7 can lift the concentrate frame 8 from inside the tailings frame 9, which is convenient for collecting the internal mineral raw materials.
[0035] In this embodiment, as Figure 5As shown, the synchronous pulleys 804 are connected by a belt, and the steel brush heads 803 are rotatably connected to the inside of the concentrate frame 8 via a servo motor mounted on the surface of the cross beam frame 802. Although the minerals are washed on the surface of the raw materials by the nozzles 405 during screening in the sorting box 5, to avoid adding a subsequent concentrate surface cleaning process, an array of steel brush heads 803 is added inside the concentrate frame 8. Connected to the belt by the synchronous pulleys 804, when one set of steel brush heads 803 is driven, the steel brush heads 803 at both ends rotate simultaneously. The quality of the concentrate directly affects the efficiency and cost of metal extraction, so cleaning the impurities on the surface of the concentrate is essential. The rotating structure of the steel brush head 803 removes the surface impurities, thereby improving the grade of the concentrate and making the subsequent refining process more efficient. The concentrate frame 8 has a hollow structure, which can achieve the purpose of final screening of mineral raw materials. At the same time, when it is inside the tailings frame 9, the water flow inside the tailings frame 9 and the rotating steel brush head 803 clean the raw materials inside, achieving the effect of removing impurities.
[0036] In this embodiment, as Figure 5 As shown, one end of the tailings frame 9 forms a lifting structure between the inner walls of the rear support 6 via a hydraulic column 10, and the tailings discharge plate 902 forms an opening and closing structure on the surface of the tailings frame 9 via an electric telescopic rod 901. The concentrate discharge plate 805 is on the same side as the tailings discharge plate 902. After the concentrate has undergone final screening and washing, it is lifted from inside the tailings frame 9 via the transmission structure of the screw 7 using the concentrate frame 8 to drain excess water. The tailings and wastewater screened through the perforated openings of the concentrate frame 8 remain inside the tailings frame 9. It should be noted that... The bottom of the tailings frame 9 is equipped with a drain outlet. The internal medium can be extracted through the drain outlet using a water pump and pipeline. To facilitate the extraction of solid raw materials, the hydraulic column 10 can be used to tilt the tailings frame 9. The telescopic structure of the electric telescopic rod 901 can realize the automatic opening and closing of the tailings discharge plate 902 to complete the extraction of internal tailings raw materials. At the same time, the two ends of the tailings discharge plate 902 are tenon-and-mortise connected to one side of the tailings frame 9, and the tenon joints are sealed with rubber strips to ensure that the internal medium of the tailings frame 9 will not overflow.
[0037] The usage and advantages of this utility model: The automatic washing and sorting machine operates as follows:
[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the material is first fed onto the conveyor 3. Driven by the motor, the conveyor 3, in a transmission structure, transports the surface material to the inside of the feed box 2. Since the feed box 2 is an inclined structure, the material falls under gravity and continuous pushing. During this process, the air compressor 204 delivers high-pressure airflow to the material through the pipe and the fan 203 via the air inlet 202. The airflow blows non-compliant mineral impurities mixed in with the minerals down through the spray nozzle 201 to the collection chamber 205, while the compliant minerals accumulate on the surface of the screen plate 501 as they fall. Due to the vibration structure of the vibrating motor 502, the sorting box... 5. Continuous vibration occurs as the nozzle 405, supplied with cleaning medium via a water pump and external water supply equipment, causes the raw material to fall progressively over the vibrating surface of the screen plate 501. The top nozzle 405 further washes the raw material, removing clay that the surface airflow cannot remove. Non-compliant minerals and impurities flow through the screen plate 501 to the bottom of the sorting box 5 below, and continue to fall progressively through the through-holes at the bottom of the sorting box 5 into the collection tank 403. The material retained on the screen plate 501 flows into the concentrate frame 8 and then into the tailings frame 9. The interior contains a medium for cleaning the final extract. Raw materials that do not meet mineral specifications flow into the tailings frame 9 through the through-holes of the concentrate frame 8. Driven by a servo motor at the top of the cross beam frame 802, the synchronous pulley 804 drives several steel brush heads 803 to rotate simultaneously, cleaning the material on the surface of the concentrate frame 8. After the final screening and cleaning, the servo motor drives the lead screw 7 to rotate. Under the belt structure, the rotation of the two sets of lead screws 7 causes the nut in the transmission structure to lift and lower the connecting frame 801, thereby lifting the concentrate frame 8 loaded with material from inside the tailings frame 9. Sewage and non-composite materials are removed. The raw materials of the specified specifications will be trapped inside the tailings frame 9. The concentrate can be extracted from the inside through the concentrate discharge plate 805. When extracting the tailings, the internal sewage is discharged through the drainage port inside the tailings frame 9 in advance. The lifting structure of the hydraulic column 10 makes the tailings frame 9 tilted. The telescopic structure of the electric telescopic rod 901 can realize the automatic opening and closing of the tailings discharge plate 902, thereby completing the extraction of the internal tailings raw materials. The washing and screening of mineral raw materials is completed under the condition of effectively saving water resources. Moreover, this equipment occupies less area than general washing and screening equipment. It completes the washing and screening of minerals through step-by-step screening.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
