Technical Field
[0001] This utility model relates to the field of quartz sand filter media processing technology, and in particular to a quartz sand filter media grading and screening device. Background Technology
[0002] Quartz sand filter media is a commonly used material in water treatment, filtration and other fields. The uniformity and purity of its particle size directly affect its performance. Therefore, it is essential to accurately classify and screen quartz sand filter media.
[0003] Chinese Patent Publication No. CN222267884U discloses a quartz sand filter media grading and screening device, including a housing with a first screening plate and a second screening plate inside; and an inclined baffle, which is inclinedly arranged between the first screening plate and the second screening plate to support the quartz sand falling from the first screening plate. The lower end of the inclined baffle faces the higher end of the second screening plate. The quartz sand filter media grading and screening device provided by this utility model can avoid the quartz sand particles screened off the first screening plate from directly hitting the second screening plate and being ejected directly from the second discharge port by the presence of the inclined baffle, thereby improving the screening quality of the quartz sand. Secondly, the presence of the inclined baffle can guide the falling quartz sand particles to roll towards the higher end of the second screening plate, thereby increasing the horizontal movement distance of the quartz sand particles on the second screening plate and improving the screening quality of small quartz sand particles. The aforementioned patent documents still have the following defects in practice: Traditional equipment does not have a batch feeding structure, so a large amount of quartz sand may flood into the screening area at once, causing excessive load on the screening plate. This not only reduces screening efficiency but may also lead to incomplete screening due to material accumulation. Summary of the Invention
[0004] The main objective of this invention is to provide a quartz sand filter media grading and screening device that can effectively solve the problems mentioned above.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A quartz sand filter media grading and screening device includes four legs, with a housing fixedly connected to the upper ends of the four legs. A support plate is fixedly connected to the middle of the outer surface of the housing. A discharge mechanism is fixedly connected to the upper part of the housing, and a feeding mechanism is fixedly connected to the upper end of the housing. Two opposing filter plates are fixedly connected to the lower part of the outer surface of the housing. An arc-shaped plate is fixedly connected to the side of the housing away from the support plate. A fan is fixedly connected to the end of the arc-shaped plate away from the housing. A stirring mechanism is fixedly connected to the middle of the inner cavity of the housing.
[0006] Preferably, the upper part of the outer shell has a square groove, the lower end of the outer shell is conical, and the lower end of the conical outer shell is an opening.
[0007] Preferably, the discharge mechanism includes a guide plate, an arc-shaped baffle, and a second latch. The guide plate is fixedly connected to the outer surface of the outer shell. The right side of the arc-shaped baffle is rotatably connected to the right side of the square groove on the upper part of the outer shell. A first latch is fixedly connected to the left rear end of the arc-shaped baffle. The front end of the second latch is fixedly connected to the outer surface of the outer shell.
[0008] Preferably, the first latch and the second latch are magnetically connected, and the arc-shaped stop bar is located at the lower part of the square groove on the upper part of the outer shell.
[0009] Preferably, the feeding mechanism includes a fixed frame, the lower end of which is fixedly connected to the upper end of the outer shell, a motor is fixedly connected to the upper part of the fixed frame, and a gear is fixedly connected to the outer surface of the motor output end.
[0010] Preferably, the feeding mechanism further includes a fixed rod and two support rods. The lower end of the fixed rod is fixedly connected to the upper end of the outer shell. A gear two is rotatably connected to the outer surface of the fixed rod. The lower ends of the two support rods are fixedly connected to the upper end of the outer shell. The upper ends of the two support rods are jointly fixedly connected to a feeding hopper. The gear two has a circular groove. The gear one meshes with the gear two.
[0011] Preferably, the stirring mechanism includes a sieve plate and a connecting rod. The outer surface of the sieve plate is fixedly connected to the middle of the inner cavity of the outer shell. The upper end of the connecting rod is fixedly connected to the output end of the motor. Several scrapers are fixedly connected to the upper part of the connecting rod, and several stirring blades are fixedly connected to the lower part of the connecting rod. The lower end of the scraper is in contact with the upper end of the sieve plate.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this embodiment, a feeding mechanism is set up. The motor drives gear one to rotate, which in turn drives gear two to rotate. The circular groove on gear two enables the quantitative and batch feeding of quartz sand into the inner cavity of the outer shell. This avoids the problem of a large amount of quartz sand flooding into the screening area at once in traditional equipment, effectively reducing the load on the screening plate, making the screening process more uniform and thorough, and significantly improving screening efficiency. 2. In this embodiment, a stirring mechanism is installed. The sieve plate and scraper work together. When the motor drives the connecting rod to rotate, the scraper pushes the quartz sand to move on the sieve plate. Smaller particles fall through the sieve holes into the lower part of the outer shell, while larger particles remain on the sieve plate. At the same time, the stirring blades stir below the sieve plate, increasing the residence time of the quartz sand and ensuring that quartz sand of different particle sizes is fully separated, thereby improving the uniformity of particle size.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] Example 1, as Figures 1-2 As shown, a quartz sand filter media grading and screening device includes four support legs 1, with a housing 2 fixedly connected to the upper ends of the four support legs 1. A support plate 3 is fixedly connected to the middle of the outer surface of the housing 2. A discharge mechanism 4 is fixedly connected to the upper part of the housing 2. A feeding mechanism 5 is fixedly connected to the upper end of the housing 2. Two opposing filter plates 8 are fixedly connected to the lower part of the outer surface of the housing 2. An arc-shaped plate 7 is fixedly connected to the side of the housing 2 away from the support plate 3. A blower 6 is fixedly connected to the end of the arc-shaped plate 7 away from the housing 2. A stirring mechanism 9 is fixedly connected to the middle of the inner cavity of the housing 2. A square groove is opened on the upper part of the housing 2. The lower end of the housing 2 is conical and has an opening at the lower end of the conical shape. In this embodiment, the quartz sand to be screened is placed in the feeding mechanism 5. The feeding mechanism 5 is started, and the quartz sand in the feeding mechanism 5 falls into the outer shell 2 and onto the upper part of the stirring mechanism 9. Smaller quartz sand falls into the lower part of the outer shell 2, and larger quartz sand falls out into another collection frame through the discharge mechanism 4. It falls into the collection frame from the lower opening of the outer shell 2. The blower 6 is started, and the blower 6 blows the ash in the smaller quartz sand out from the rear filter plate 8. To achieve batch feeding and more thorough screening, please refer to [the relevant documentation / reference]. Figure 4The feeding mechanism 5 includes a fixed frame 51, the lower end of which is fixedly connected to the upper end of the outer shell 2. A motor 52 is fixedly connected to the upper part of the fixed frame 51. A gear 53 is fixedly connected to the outer surface of the output end of the motor 52. The feeding mechanism 5 also includes a fixed rod 54 and two support rods 57. The lower end of the fixed rod 54 is fixedly connected to the upper end of the outer shell 2. A gear 55 is rotatably connected to the outer surface of the fixed rod 54. The lower ends of the two support rods 57 are fixedly connected to the upper end of the outer shell 2. A feeding hopper 56 is fixedly connected to the upper ends of the two support rods 57. A circular groove is opened in the gear 55. The gear 53 meshes with the gear 55. During the process, the quartz sand to be screened is placed in the feed hopper 56, the motor 52 is started, the motor 52 drives the gear 1 53 to rotate, the gear 1 53 drives the gear 2 55 to rotate, and the gear 2 55 drives the circular groove on the gear 2 55 to rotate. When the groove is located at the lower end of the feed hopper 56, the quartz sand in the feed hopper 56 falls into the inner cavity of the outer shell 2 through the circular groove on the gear 2 55 and the opening at the upper end of the outer shell 2.
[0017] Example 2: For screening quartz sand, refer to... Figure 5 The stirring mechanism 9 includes a sieve plate 93 and a connecting rod 91. The outer surface of the sieve plate 93 is fixedly connected to the middle of the inner cavity of the outer shell 2. The upper end of the connecting rod 91 is fixedly connected to the output end of the motor 52. Several scrapers 92 are fixedly connected to the upper part of the connecting rod 91, and several stirring blades 94 are fixedly connected to the lower part of the connecting rod 91. The lower end of the scraper 92 is in contact with the upper end of the sieve plate 93. During implementation, the scraper 92 is arc-shaped and contacts the upper end of the sieve plate 93. The motor 52 drives the stirring mechanism 9 to rotate clockwise. The quartz sand falling on the upper end of the sieve plate 93 is driven by the scraper 92 and moves on the upper end of the sieve plate 93. Larger quartz sand remains on the upper end of the sieve plate 93, while smaller quartz sand falls from the sieve holes on the sieve plate 93 into the lower part of the outer shell 2. The feeding mechanism 5 is located to the left of the discharging mechanism 4, so that the quartz sand is driven 270 degrees before moving to the discharging mechanism 4. When it falls from the sieve holes on the sieve plate 93 to the lower part of the outer shell 2, the stirring blades 94 increase the time that the quartz sand stays in the lower part of the sieve plate 93, so that the dust in the quartz sand is fully blown out by the blower 6 from the rear filter plate 8. The screened quartz sand then falls out from the lower part of the outer shell 2. To ensure a continuous discharge of larger quartz sand samples, please refer to [reference needed]. Figure 3 The discharge mechanism 4 includes a guide plate 41, an arc-shaped baffle 42, and a second lock 44. The guide plate 41 is fixedly connected to the outer surface of the outer shell 2. The right side of the arc-shaped baffle 42 is rotatably connected to the right side of the upper square groove of the outer shell 2. A first lock 43 is fixedly connected to the left rear end of the arc-shaped baffle 42. The front end of the second lock 44 is fixedly connected to the outer surface of the outer shell 2. The first lock 43 and the second lock 44 are magnetically connected. The arc-shaped baffle 42 is located at the lower part of the upper square groove of the outer shell 2. During implementation, when the thickness of the upper end of the sieve plate 93 exceeds the height of the arc-shaped baffle 42, the excess quartz sand falls from the upper end of the arc-shaped baffle 42 to the guide plate 41, and then falls onto the collection frame through the guide plate 41. After screening, the magnetic attraction between the locking buckle 1 43 and the locking buckle 2 44 is released, the arc-shaped baffle 42 is opened, and the worker can remove the quartz sand from the upper end of the sieve plate 93. The connecting rod 91 rotates at a speed of 20 revolutions per minute, which can drive the scraper 92 to rotate without affecting the worker's ability to remove the quartz sand. Example 3: To prevent dust blown out of the outer casing 2 from polluting the environment, refer to... Figure 2 ; During implementation, a dust collection hood can be installed at the rear filter plate 8, and a dust collection bag can be installed at the rear of the dust collection hood. This can collect dust and ensure air circulation. After screening, the dust collection bag can be removed for easy cleaning.
