Technical Field

[0001] This utility model relates to the field of gypsum filtration technology, specifically to a gypsum-based self-leveling raw material filtration device for spinning and dispersing materials. Background Technology

[0002] Gypsum-based self-leveling materials use gypsum as the main ingredient, combined with appropriate additives and aggregates, to achieve the effect of leveling the ground through proper proportioning. To ensure the quality of gypsum-based self-leveling materials and smooth construction, it is necessary to filter the gypsum-based self-leveling materials.

[0003] To overcome the aforementioned shortcomings, a prior art Chinese patent (publication number: CN221360957U) discloses a filtration and screening device for gypsum-based self-leveling raw materials. The device includes a frame, a rotating hopper, a screen, and a fixed hopper. The bottom of the rotating hopper is a cylindrical fine material outlet. A drive unit connected to the rotating hopper is located on its outer side, comprising two symmetrically distributed motors. An elevated hopper is located at the top of the rotating hopper, with multiple baffles on its inner wall. The screen has a conical structure with multiple reinforcing baffles distributed along its sides. A discharge port is located on the side of the rotating hopper. The fixed hopper includes a ring-shaped portion that cooperates with the rotating hopper. Discharge hoppers, connected to the left and right sides of the discharge port, are located on the ring-shaped portion at positions corresponding to the discharge port. This device enables diverted discharge, improves screening efficiency, and has a high overall utilization rate, making it suitable for large-scale promotion.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: local crystallization and agglomeration are easily generated during the dissolution of gypsum raw materials, and traditional equipment only separates particles through a single filter screen without secondary treatment of the agglomerates, resulting in the loss of effective gypsum components in the filtered raw materials and the slurry concentration failing to meet the mixing ratio requirements of self-leveling materials. Utility Model Content

[0005] The purpose of this invention is to provide a raw material filtration device for gypsum-based self-leveling compound that uses spinning bulk material, in order to solve the problem in the above-mentioned background technology that traditional equipment only separates particles through a single filter screen and does not perform secondary treatment on the agglomerates, resulting in the loss of effective gypsum components in the filtered raw material and the inability of the slurry concentration to meet the ratio requirements of the self-leveling material.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material filtration device for gypsum-based self-leveling compound with self-spinning material, comprising a filter chamber, wherein a feed hopper is fixedly connected to the top of the filter chamber, and the lower end of the feed hopper extends into the interior of the filter chamber;

[0008] Preferably, a tapered filter screen is fixedly connected to the top center of the grinding mesh, the filter screen is coaxially aligned with the lower end of the feed hopper, and the filter screen has evenly distributed openings on its outer side.

[0009] Preferably, the filter screen is disposed in the central opening of the grinding ring, and the lower end of the feed hopper extends into the central opening of the grinding ring.

[0010] Preferably, there are equidistant guide holes between the outer side of the grinding mesh and the inner wall of the filter chamber, and the guide holes are arranged around the bottom periphery of the grinding ring.

[0011] Preferably, an annular guide rail is fixedly provided on the inner wall of the filter chamber, and the grinding ring is rotatably connected to the guide rail through a pulley assembly. An installation chamber is provided on one side of the filter chamber, and a motor is fixedly installed inside the installation chamber. The output end of the motor is connected to a gear.

[0012] Preferably, the grinding ring has annularly evenly distributed teeth on its upper outer side, the teeth meshing with gears for transmission, and the rollers of the pulley assembly forming a rolling fit with the inner groove of the guide rail.

[0013] Preferably, the bottom of the filter chamber is connected to a discharge hopper and a shaped tube. The discharge hopper is located inside the shaped tube and its upper end is connected to the grinding screen. The upper end of the shaped tube is connected to the guide hole, and its bottom inclined end is provided with a discharge port. The bottom surface of the shaped tube is a downward slope facing the discharge port.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This self-spinning gypsum-based self-leveling material filtration device uses a gradually narrowing grinding gap formed by an integrated grinding mesh and a rotating grinding ring to dynamically break up gypsum nodules intercepted by the filter screen, effectively avoiding the loss of raw material concentration caused by direct separation of nodules.

[0016] The directional discharge design using guide holes and irregularly shaped pipes allows for the discharge of insufficiently ground, substandard particles, facilitating the remelting and reuse of gypsum nodules, reducing raw material waste, and ensuring that the slurry concentration meets construction standards.

[0024] 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.

[0025] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: a raw material filtration device for gypsum-based self-leveling compound with self-spinning material, comprising a filter chamber 1, a feed hopper 2 fixedly connected to the top of the filter chamber 1, and the lower end of the feed hopper 2 extending into the interior of the filter chamber 1; a filter structure is installed inside the filter chamber 1, the filter structure including a grinding screen 3 fixedly connected inside the filter chamber 1, a grinding ring 5 rotatably connected inside the filter chamber 1, the grinding ring 5 and the grinding screen 3 being aligned at the top and forming a gradually narrowing grinding gap between them, a conical filter screen 4 fixedly connected to the top of the middle of the grinding screen 3, the filter screen 4 being coaxially aligned with the lower end of the feed hopper 2, and the outer side of the filter screen 4 having evenly distributed perforated filter screen 4 located in the central opening of the grinding ring 5, the lower end of the feed hopper 2 extending into the central opening of the grinding ring 5, and a gap between the outer side of the grinding screen 3 and the inner wall of the filter chamber 1. The filter chamber 1 has equidistantly distributed guide holes 6. The guide holes 6 are arranged around the bottom periphery of the grinding ring 5. The inner wall of the filter chamber 1 is fixed with an annular guide rail 7. The grinding ring 5 is rotatably connected to the guide rail 7 through the pulley assembly 12. The filter chamber 1 has an installation chamber 8 on one side. The installation chamber 8 has a motor 9 fixedly installed inside. The output end of the motor 9 is connected to a gear 10. The outer side of the upper end of the grinding ring 5 has annularly distributed gear teeth 11. The gear teeth 11 mesh with the gear 10 for transmission. The rollers of the pulley assembly 12 and the inner groove of the guide rail 7 form a rolling fit. The bottom of the filter chamber 1 is connected to a discharge hopper 13 and a special-shaped tube 14. The discharge hopper 13 is located inside the special-shaped tube 14 and its upper end is connected to the grinding mesh 3. The upper end of the special-shaped tube 14 is connected to the guide holes 6. Its bottom inclined end has a discharge port 15. The bottom surface of the special-shaped tube 14 is a downward slope facing the discharge port 15.

[0026] When the device is working, the gypsum raw material first enters the filter chamber 1 through the feed hopper 2. Under the action of gravity, the raw material falls to the top of the conical filter screen 4. Fine particles that meet the particle size requirements directly penetrate the evenly distributed openings on the outside of the filter screen 4 and are quickly discharged through the discharge hopper 13 to complete the preliminary sorting. Coarse particles that do not pass through the filter slide along the conical surface of the filter screen 4 to the gradually narrowing grinding gap between the grinding screen 3 and the grinding ring 5.

[0027] When the motor 9 starts, the grinding ring 5 is driven to rotate smoothly along the annular guide rail 7 through the meshing transmission of the gear 10 and the outer gear teeth 11 of the grinding ring 5. During this process, the rollers of the pulley assembly 12 and the inner groove of the guide rail 7 form a rolling fit to ensure that the grinding ring 5 maintains stable alignment when rotating at high speed. Under the rotational extrusion of the grinding ring 5, the coarse raw materials are repeatedly crushed in the gradually narrowing grinding gap until the particle size is reduced to be able to pass through the mesh of the grinding screen 3, and finally flow into the discharge hopper 13 to output qualified materials.

[0028] For a very small amount of ultra-hard impurities that cannot be ground, under the centrifugal force generated by the rotation of the grinding ring 5, they enter the shaped tube 14 through the guide hole 6. The inclined bottom surface of the shaped tube 14 forms a slide that is inclined towards the discharge port 15. Under the guidance of gravity, the impurities automatically slide to the discharge port 15 and are discharged in a concentrated manner, effectively avoiding equipment blockage caused by the accumulation of impurities. The entire workflow realizes the coordinated operation of continuous filtration, graded grinding and impurity separation of raw materials, significantly improving the preparation efficiency of gypsum-based self-leveling raw materials.
