Description

Technical Field

[0001] This utility model relates to the field of quartz powder processing technology, specifically to a novel quartz powder grading device. Background Technology

[0002] Chinese patent publication number "CN221086316U" entitled "A Quartz Powder Grading Device" discloses an outer casing with a feed pipe interconnected at the top. A storage box, also connected to the feed pipe, is fixedly connected to the top of the outer casing via a support rod. Three equidistant grading screens with progressively decreasing apertures are slidably connected inside the outer casing. A motor is mounted on the top of the feed pipe via a motor platform, and a rotating shaft is fixedly connected to the motor's output shaft. A discharge plate is fixedly fitted around the rotating shaft, located inside the feed pipe. Inclined plates are fixedly connected to the bottom of the grading screens. Multiple collection boxes are interconnected on the right side of the outer casing, and a bottom box is placed on the inner wall of the bottom of the outer casing. This invention can perform multi-stage sieving of quartz powder, and the sieved quartz powder can be classified and stored for convenient subsequent retrieval and use.

[0003] Although this patent can perform multi-stage screening, the drive of each screen is achieved by rotating irregular blocks 15 driving the lever 14 to move up and down. When the lever 14 moves to the point where the irregular blocks 15 are separated at different heights, the lever 14 falls and hits the lowest end of the irregular block 15, which can easily lead to damage to the lever 14 or the irregular block 15, thus limiting its service life. Utility Model Content

[0004] The purpose of this invention is to provide a novel quartz powder grading device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel quartz powder grading device includes a housing, in which an upper filter screen and a lower filter screen are fixedly installed respectively. A vibration mechanism is provided between the upper filter screen and the lower filter screen. The vibration mechanism includes a sliding part that is slidably installed in the housing. Multiple vibration parts are evenly arranged along the circumferential direction of the housing on the sliding part. Cylinders are fixedly installed on both sides of the housing respectively. A locking block is fixedly connected to the output end of the cylinder and the locking block is engaged with the sliding part.

[0006] Furthermore, the vibrating mechanism also includes a guide seat fixedly disposed inside the box body. The guide seat has a closed guide groove opened along the circumferential direction of the box body. A guide rod is fixedly connected to the sliding part. The guide rod extends into and is slidably connected to the guide groove. The sliding part is slidably connected to the guide seat.

[0007] Furthermore, the guide groove includes multiple adjacent lifting grooves, which are arranged in a V-shape. When the guide rod slides in the lifting groove, the guide rod moves along the axial direction of the box body.

[0008] Furthermore, the sliding seat includes a sliding cylinder slidably connected to the guide seat, the guide rod is fixedly disposed on the outer wall of the sliding cylinder, each of the vibration parts is disposed inside the sliding cylinder, and an annular groove adapted to the locking block is opened at the bottom of the sliding cylinder.

[0009] Furthermore, the vibrating part includes a support rod fixedly disposed inside the sliding cylinder, and a plurality of vibrating rods are fixedly disposed on the support rod.

[0010] Furthermore, the vibrating plates of adjacent vibrating parts are arranged in an alternating manner.

[0011] Furthermore, each of the vibrating rods is provided with a protective pad at its end.

[0012] The novel quartz powder grading device provided by this utility model has the following beneficial effects as described above: Through the designed vibration mechanism, the cylinder drives the clamping block to move up and down. The movement of the clamping block drives the movement of each vibrating part through the sliding part. The vibrating parts collide with the upper and lower filter screens respectively, causing the upper and lower filter screens to vibrate, thereby screening the quartz sand. Furthermore, the collision of the vibrating parts with the upper and lower filter screens can also move the quartz sand clogged inside the filter screens, thus cleaning the filter screens. This utility model, by changing the vibration structure, avoids the problem of short lifespan caused by collisions and can also unclog the filter screens while screening.

[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0019] Please see Figure 1-9 A novel quartz powder grading device includes a housing 1, in which an upper filter screen 11 and a lower filter screen 12 are fixedly installed. A vibration mechanism is provided between the upper filter screen 11 and the lower filter screen 12. The vibration mechanism includes a sliding part 2 slidably installed in the housing 1. Multiple vibration parts 3 are evenly arranged along the circumferential direction of the housing 1 on the sliding part 2. Cylinders 4 are fixedly installed on both sides of the housing 1. A locking block 41 is fixedly connected to the output end of the cylinder 4 and the locking block 41 is engaged with the sliding part 2.

[0020] The upper and lower parts of the box 1 are respectively provided with a feed inlet and a discharge outlet; the upper filter screen 11 and the lower filter screen 12 are both convex in shape with the middle higher and the sides lower, so that the quartz sand that fails to pass through the filter screen enters the discharge trough 13 of the box 1. The discharge trough 13 is annular and is inclined inside the box 1, so that the quartz sand in the discharge trough 13 enters the discharge outlet on the box 1 under the action of gravity, and is discharged from the box 1; the aperture of the upper filter screen 11 is larger than the aperture of the lower filter screen 12 for grading and screening.

[0021] Furthermore, the vibration mechanism also includes a guide seat 5 fixedly disposed inside the housing 1. The guide seat 5 has a closed guide groove 51 opened along the circumferential direction of the housing 1. A guide rod 21 is fixedly connected to the sliding part 2. The guide rod 21 extends into and is slidably connected to the guide groove 51. The sliding part 2 is slidably connected to the guide seat 5.

[0022] The vibrating section 3 has a dead zone in its vibration of the upper filter screen 11 and the lower filter screen 12, meaning that some quartz sand may be trapped or blocked between adjacent vibrating sections 3. However, the guide seat 5 and guide groove 51 allow the sliding section 2 to drive the vibrating section 3 to move up and down while simultaneously rotating it, thus providing sufficient vibration to the upper filter screen 11 and the lower filter screen 12 for effective quartz sand screening and filter screen cleaning.

[0023] Furthermore, the guide groove 51 includes a plurality of adjacent lifting grooves 52, the lifting grooves 52 being arranged in a V-shape, and when the guide rod 21 slides within the lifting groove 52, the guide rod 21 moves along the axial direction of the housing 1.

[0024] See attached document Figure 4 and attached Figure 6 The guide rod 21 is slidably connected to the guide groove 51. In order to ensure the stability of the sliding part 2 during movement, multiple guide rods 21 are fixedly and evenly arranged in the circumferential direction of the sliding part 2. Each guide rod 21 extends into each lifting groove 52 and is kept on the same horizontal plane. In other words, the height of each guide rod 21 in each lifting groove 52 is the same at any time, thereby ensuring the stability of the sliding part 2 during movement.

[0025] See attached document Figure 9 (Partial schematic diagram of the circumferential lifting groove 52 unfolded into a plane) When the sliding part 2 drives each guide rod 21 to move along the lifting groove 52, in order to ensure that the sliding part 2 can rotate in the same direction, the top of each lifting groove 52 is provided with a first empty groove 53 so that when the guide rod 21 descends, it can only move in the rotation direction of the sliding part 2. The bottom of each lifting groove 52 (i.e. the connection between adjacent lifting grooves 52) is provided with a second empty groove 54 so that when the guide rod 21 rises, it can only move in the rotation direction of the sliding part 2.

[0026] Furthermore, the sliding seat includes a sliding cylinder 22 slidably connected to the guide seat 5, the guide rod 21 is fixedly disposed on the outer wall of the sliding cylinder 22, each of the vibration parts 3 is disposed inside the sliding cylinder 22, and the bottom of the sliding cylinder 22 is provided with an annular groove that matches the locking block 41.

[0027] Furthermore, the vibration unit 3 includes a support rod 31 fixedly disposed within the sliding cylinder 22, and a plurality of vibrating rods 32 are fixedly disposed on the support rod 31. The ends of each support rod 31 are fixedly connected to a central support column, which is disposed within the sliding cylinder 22, to improve the stability of each support rod 31.

[0028] Furthermore, the vibrating plates of adjacent vibrating parts 3 are staggered. This ensures that during the rotation of the vibrating parts 3 driven by the sliding part 2, the contact surfaces between adjacent vibrating parts 3 and the upper filter screen 11 and lower filter screen 12 are different, thereby increasing the vibration surface and cleaning surface.

[0029] Furthermore, each of the vibrating rods 32 has a protective pad at its end. This prevents the vibrating rods 32 from damaging the upper filter screen 11 and the lower filter screen 12. Alternatively, the vibrating rods 32 can be made into a hollow structure to reduce the inertia of the vibrating rods 32, thereby further protecting the upper filter screen 11 and the lower filter screen 12.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
