[0002] In the current technical field of solid-liquid separation, with the continuous expansion of industrial production scale and the increasing diversification of material properties, the requirements for solid-liquid separation equipment are also getting higher and higher. Traditional solid-liquid separation equipment, such as sieves, centrifuges, etc., although can achieve the purpose of solid-liquid separation to a certain extent, but expose many deficiencies in practical applications.

[0003] First of all, traditional equipment often has bottlenecks in separation efficiency. Due to design limitations, these equipment are difficult to flexibly adjust the separation speed according to material properties and production requirements, resulting in unsatisfactory separation effects when dealing with certain specific materials, and even requiring multiple treatments to achieve the expected effect, thus increasing production costs and time costs.

[0004] Secondly, traditional equipment also has obvious deficiencies in flexibility. Different materials have different requirements for separation conditions, while traditional equipment often lacks sufficient adjustment ability and cannot quickly adapt to the separation needs of different materials. This not only limits the application range of the equipment, but also reduces the overall efficiency of the production line.

[0005] In addition, traditional equipment also faces many challenges in cleaning and maintenance. Due to the complex structure of the equipment, cleaning and maintenance work often requires a large amount of manpower and time investment. At the same time, due to the easy accumulation of residues inside the equipment, the equipment performance may decline after long-term operation, and even lead to failures and safety accidents. Therefore, we provide an internal flow grid solid-liquid separator. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figures 1-4 , an internal flow grille solid-liquid separator mainly consists of a fixed frame plate 1 and a collection box 2. The collection box 2 is used to hold the solid-liquid substances separated by the grille plate 4. A partition plate 3 is fixedly connected to the inner wall of the collection box 2 to separate the internal space of the collection box 2, facilitating the classified storage of solid-liquid substances. A liquid outlet pipe 20 is installed through one end of the collection box 2 to facilitate the discharge of the separated liquid; the fixed frame plate 1 serves as the basic support structure of the entire separator, and a grille plate 4 is rotatably connected to its inner wall through a rotating shaft. The design of the grille plate 4 enables the solid-liquid mixture to achieve solid-liquid separation when passing through. The solid substances are intercepted on the grille plate 4, while the liquid flows into the collection box 2 through the gaps of the grille plate 4; in order to adjust the solid-liquid separation speed according to production requirements, an inclination angle adjustment mechanism is provided between the collection box 2 and the grille plate 4 in this embodiment. This mechanism specifically includes a shaft rotating rod 6 rotatably connected to both sides of one end of the grille plate 4 through a rotating shaft and a groove-type horizontal fixing plate 5 fixedly connected to the side of the collection box 2. The groove-type horizontal fixing plate 5 is designed with a structure having a chute inside to facilitate the sliding connection of the moving plate 9.

[0027] Among them, a rotating connecting rod 10 is rotatably connected to the surface of the moving plate 9 through a rotating shaft, and the other end of the rotating connecting rod 10 is rotatably connected to the end of the shaft rotating rod 6 through a bearing. This connection method enables the shaft rotating rod 6 to be driven to rotate by the rotating connecting rod 10 when the moving plate 9 slides in the groove-type horizontal fixing plate 5, thereby adjusting the inclination angle of the grille plate 4. The change in the inclination angle will affect the residence time and passing speed of the solid-liquid mixture on the grille plate 4, thereby realizing the adjustment of the solid-liquid separation speed; in order to limit the continuous sliding of the moving plate 9 and ensure that the grille plate 4 can be stably maintained at the required inclination angle, a torsion fixing screw 11 is threadedly connected to the surface of the moving plate 9 in this embodiment. The end of the torsion fixing screw 11 penetrates through the moving plate 9 and abuts against the inner bottom wall of the groove-type horizontal fixing plate 5. By rotating the torsion fixing screw 11, sufficient friction can be generated between its end and the inner bottom wall of the groove-type horizontal fixing plate 5 to fix the inclination angles of the moving plate 9 and the grille plate 4.

[0028] Furthermore, in order to more effectively push the liquid in the collection box 2 to the liquid outlet pipe 20 for discharge, a drainage assembly is connected inside the collection box 2 in this embodiment. The drainage assembly includes a scraping plate 12 slidably connected to the inner wall of the collection box 2. The scraping plate 12 is designed to slide in a specific direction in the collection box 2, thereby pushing the liquid to flow in the direction of the liquid outlet pipe 20. A pulling rod 13 is inserted at the end of the collection box 2, and one end of the pulling rod 13 is fixedly connected to the surface of the scraping plate 12, so that the sliding of the scraping plate 12 can be controlled by operating the pulling rod 13. In order to operate two scraping plates 12 at the same time, the ends of the two pulling rods 13 are fixedly connected with a lap plate 14, so that the two scraping plates 12 can be pulled or pushed at the same time. In addition, a reset component is also connected between the grooved transverse fixing plate 5 and the lap plate 14, which is used to automatically reset the scraping plate 12 to the initial position after the lap plate 14 is released.

[0029] Furthermore, the specific implementation of the reset component includes a placement strip groove 15 provided on the side of the groove-type transverse fixing plate 5. A transverse fixing rod 16 is fixedly connected between the two end walls of the placement strip groove 15, and a spring 17 is sleeved on the periphery of the transverse fixing rod 16 to provide elastic force for reset. A sleeve block 18 is also slidably sleeved on the periphery of the transverse fixing rod 16, and the sleeve block 18 is slidably connected at the inner wall of the placement strip groove 15 to ensure its stable sliding trajectory. A connecting rod 19 is fixedly connected between the lap plate 14 and the sleeve block 18. When the lap plate 14 is pulled or pushed, the sleeve block 18 is driven by the connecting rod 19 to slide on the transverse fixing rod 16 and compress or stretch the spring 17. After the lap plate 14 is released, the elastic force of the spring 17 will reset the sleeve block 18 and the lap plate 14 to the initial position, thereby driving the scraper plate 12 to reset.

[0030] Furthermore, in order to improve the stability and smoothness of the sliding of the movable plate 9 in the grooved transverse fixing plate 5, a guide slide structure is connected between the grooved transverse fixing plate 5 and the movable plate 9 in this embodiment. The guide slide structure includes a guide slide groove 7 provided on the inner side wall of the grooved transverse fixing plate 5, a guide slide block 8 is slidably connected to the inner wall of the guide slide groove 7, and the side of the guide slide block 8 is fixedly connected to the side of the movable plate 9. This design enables the movable plate 9 to move along the track of the guide slide groove 7 during the sliding process, reduces friction and resistance, and improves the stability and smoothness of sliding.

[0031] Furthermore, in order to further improve the drainage efficiency and cleaning effect of the scraping plate 12, the present embodiment provides an inclined slope on the surface of the scraping plate 12 facing away from the partition plate 3. When the scraping plate 12 is moving, the inclined slope can more effectively scrape the inner wall of the collection box 2, pushing the attached liquid and impurities toward the liquid outlet pipe 20, thereby achieving more thorough cleaning and drainage.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
