Technical Field

[0001] This utility model relates to the technical field of coal washing boxes, specifically a coal washing box that can collect waste materials. Background Technology

[0002] Coal engineering is an applied engineering technology discipline with coal resource development, utilization, and management as its core. It encompasses multiple fields including coal exploration, mining, processing, transportation, and clean utilization, aiming to improve coal resource utilization efficiency, ensure mine safety, and achieve green development. During coal processing, coal washing boxes are used. These boxes are specialized equipment for coal washing, primarily used to remove impurities, silt, and other unwanted substances from coal to improve coal quality and utilization efficiency.

[0003] However, large pieces of coal may contain small particles or silt. After these impurities or silt are washed out in the coal washing box, they are directly discharged from the drainage pipe. This makes it difficult to collect the impurities or silt, which can easily cause the pipe to become clogged and reduce the convenience of the coal washing box. Therefore, the current coal washing box needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a coal washing box that can collect waste materials, so as to solve the problem mentioned in the background art that the mud or small particulate impurities washed out in the current coal washing boxes on the market are directly discharged from the drainage pipe, which is not convenient to collect the impurities or mud and sand, resulting in easy blockage of the pipe and reducing the convenience of the coal washing box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal washing box for collecting waste materials, comprising a box body and a washing frame. A feeding hopper is installed on the top of the box body, and a water tank is installed on one side of the box body. A water supply assembly connects the water tank to the box body. The washing frame is located on the inner side of the box body near the bottom of the feeding hopper. A rotating mechanism is connected to both ends of the washing frame, and one side of the rotating mechanism is located on the outer wall surface of the box body. The rotating mechanism includes a gear, an electric push rod, a rotating shaft, a guide rod, and a rack. A rotating shaft is fixedly connected to both ends of the washing frame. The rotating shaft is connected to the box body through bearings, and a gear is fixedly sleeved at the end of the rotating shaft away from the washing frame.

[0006] Preferably, a rack is meshed with one side of the gear, an electric push rod connected to the rack is installed on the outer wall surface of the housing, and a guide rod that is slidably sleeved with the rack is fixedly installed on the outer side of the housing.

[0007] Preferably, a second filter plate and a first filter plate are installed on the inner side of the housing near the bottom of the cleaning frame, and the first filter plate is located below the second filter plate.

[0008] Preferably, guide plates are installed at the inner wall openings of the housing near both ends of the second filter plate, and a flow guide plate is fixed on the inner wall of the housing near the cleaning frame and the second filter plate.

[0009] Preferably, a collection mechanism is installed on the inner side of the housing near the top of the first filter plate. The collection mechanism includes a slide rod, a push plate, a lead screw, and a motor. Lead screws and slide rods are respectively installed at the slots on both sides of the inner wall of the housing, and the lead screws are connected to the housing through bearings.

[0010] Preferably, a motor connected to the lead screw via a coupling is installed on the outer wall of the housing, and a push plate is sleeved on the outer side of the lead screw and slide rod, with the bottom surface of the push plate conforming to the arc surface of the first filter plate.

[0011] Preferably, a collection port is provided on the side of the box body near the No. 1 filter plate, and a collection frame is installed on the outer side of the box body near the collection port by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Equipped with a collection mechanism, a collection frame, and a No. 1 filter plate, the washed coal is poured onto the No. 2 filter plate through the cleaning frame. Small particles or silt fall from the holes of the No. 2 filter plate onto the No. 1 filter plate. Due to the very small diameter of the filter holes in the No. 1 filter plate, only water flows through. The curved surface of the No. 1 filter plate can fully contact the impurities or water flow, blocking the small particles or silt on the surface of the No. 1 filter plate. Finally, the motor drives the lead screw to rotate, causing the lead screw to engage with the push plate. Then, one end of the push plate moves towards the collection port outside the lead screw, while the other end slides outside the slide rod. The push plate scrapes the small particles or silt on the surface of the No. 1 filter plate to the collection port. The inclined surface of the push plate can extend out of the collection port to scrape the silt or small particles of impurities into the collection frame, facilitating the rapid collection of waste materials such as silt or small particles. This allows for quick cleaning and recycling, improving the practicality of the coal washing box.

[0014] 2. Equipped with a rotating mechanism, the electric push rod extends and retracts, pushing and pulling the rack to move back and forth. Simultaneously, the rack slides on the outside of the guide rod, meshing with the gear. The rack drives the gear to rotate in both directions, which in turn drives the rotating shaft to rotate in both directions, which in turn drives the washing frame to rotate in both directions. The rotation angle does not exceed a certain degree, which can provide a certain degree of shaking to the washing frame, loosening the coal piled together, facilitating washing, reducing washing dead corners, and improving washing efficiency. Furthermore, when it is time to unload after washing, the electric push rod shortens, pulling the rack to a limited position, which can drive the gear to rotate more than a certain degree, allowing the coal in the washing frame to be poured out, facilitating unloading and improving the convenience of the coal washing box.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a coal washing box for collecting waste materials, including a box body 1 and a washing frame 8. A feeding hopper 2 is installed on the top of the box body 1, a water tank 4 is installed on one side of the box body 1, a water conveying assembly 3 is connected between the water tank 4 and the box body 1, guide plates 10 are installed at the openings of the inner wall of the box body 1 near both ends of the second filter plate 7, and a flow guide plate 13 is fixed on the inner wall of the box body 1 near the washing frame 8 and the second filter plate 7.

[0024] Please see Figures 1-4The cleaning frame 8 is located on the inner side of the box 1 near the bottom of the feed hopper 2. Both ends of the cleaning frame 8 are connected to a rotating mechanism 6, and one side of the rotating mechanism 6 is located on the outer wall surface of the box 1. The rotating mechanism 6 includes a gear 601, an electric push rod 602, a rotating shaft 603, a guide rod 604, and a rack 605. Both ends of the cleaning frame 8 are fixedly connected to the rotating shaft 603. The rotating shaft 603 is connected to the box 1 through bearings. The gear 601 is fixedly sleeved at the end of the rotating shaft 603 away from the cleaning frame 8. The rack 605 is meshed with one side of the gear 601. An electric push rod 602 connected to the rack 605 is installed on the outer wall surface of the box 1. A guide rod 604 that is slidably sleeved with the rack 605 is fixedly installed on the outer side of the box 1. The inner side of the cleaning frame 8 is provided with several through holes.

[0025] In practice, during cleaning, water rinsing is usually the only method used, which is inefficient. To address this, the electric push rod 602 can be activated to extend and retract, pushing and pulling the rack 605 back and forth. Simultaneously, the rack 605 slides outside the guide rod 604, meshing with the gear 601. The rack 605 drives the gear 601 to rotate in both directions, which in turn drives the rotating shaft 603 to rotate in both directions. This, in turn, causes the cleaning frame 8 to rotate in both directions, with the rotation angle not exceeding 60 degrees. This provides a slight shaking effect on the cleaning frame 8, loosening the coal piled together for easier rinsing, reducing blind spots, and improving rinsing efficiency. Furthermore, when unloading is required after cleaning, the electric push rod 602 can shorten, pulling the rack 605 to a designated position, allowing the gear 601 to rotate more than 120 degrees, thus emptying the coal from the cleaning frame 8 and improving the convenience of the coal cleaning box.

[0026] Please see Figures 1-3 , Figure 5 and Figure 6The inner side of the housing 1 near the bottom of the cleaning frame 8 is equipped with a second filter plate 7 and a first filter plate 5, with the first filter plate 5 located below the second filter plate 7. A collection mechanism 9 is installed on the inner side of the housing 1 near the top of the first filter plate 5. The collection mechanism 9 includes a slide rod 901, a push plate 902, a lead screw 903, and a motor 904. The lead screw 903 and slide rod 901 are respectively installed at the slots on both sides of the inner wall of the housing 1, and the lead screw 903 is connected to the housing 1 via bearings. A motor 904 connected to the lead screw 903 via a coupling is installed on the outer wall of the housing 1. A push plate 902 is sleeved on the outer side of the lead screw 903 and slide rod 901, and the push... The bottom surface of plate 902 is attached to the arc surface of filter plate 5. A collection port 11 is provided on the side of the box 1 near filter plate 5. A collection frame 12 is installed on the outer side of the box 1 near the collection port 11 by bolts. One end of the push plate 902 is threadedly connected to the lead screw 903, and the other end of the push plate 902 is slidably connected to the slide rod 901. Filter plate 5 is arc-shaped, and the cross-section of filter plate 7 is triangular. The through hole size of the cleaning frame 8 is the same as that of filter plate 7. The shape of the push plate 902 is arc-shaped, and the filter hole size of filter plate 5 is 50μm-200μm.

[0027] In practice, large pieces of coal often contain small particles or silt. These impurities or silt, after being washed out of the coal washing box, are directly discharged through the drainage pipe, making it difficult to collect and store them. This can easily clog the pipes and reduce the convenience of the coal washing box. Instead, the washed coal can be poured onto the second filter plate 7 through the washing frame 8. Small particles or silt fall through the holes of the second filter plate 7 onto the first filter plate 5. Because the filter holes of the first filter plate 5 have very small diameters, only water flows through, and the curved surface of the first filter plate 5 can fully contact the impurities or water flow, effectively blocking the small particles or silt on the first filter plate 5. Finally, the motor 904 drives the lead screw 903 to rotate, so that the lead screw 903 and the push plate 902 engage threadedly. Then, one end of the push plate 902 moves towards the collection port 11 outside the lead screw 903, while the other end of the push plate 902 slides outside the slide rod 901. The push plate 902 scrapes small particles of impurities or mud and sand on the surface of the first filter plate 5 to the collection port 11. The inclined surface of the push plate 902 can extend out of the collection port 11 to scrape mud and sand or small particles of impurities into the collection frame 12, which facilitates the rapid collection of waste materials such as mud and sand or small particles of impurities. It can be quickly cleaned and recycled, improving the practicality of the coal washing box.

[0028] Working principle: When using this coal washing box that can collect waste, coal is first put into the box 1 from the feed hopper 2, and then the coal falls into the washing frame 8. Water is then drawn into the water tank 4 through the water supply component 3 to wash the coal. Then, the rotating mechanism 6 slightly shakes the washing frame 8, which can reduce the washing dead corners and also play a certain filtering role. Finally, the rotating mechanism 6 flips the washing frame 8 to pour out the coal. The coal and water flow are guided by the guide plate 13. The coal then passes through the second filter plate 7 to filter mud or small particulate impurities. The coal rolls down from the inclined surface of the second filter plate 7 to the guide plate 10 for discharge. The mud or impurities fall onto the first filter plate 5 and are scraped off into the collection frame 12 by the collection mechanism 9 for collection, which is convenient for cleaning and improves the practicality and convenience of the coal washing box. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
