Description

Technical Field

[0001] This utility model relates to the field of horizontal screw centrifuge technology, and in particular to a horizontal screw centrifuge with a cover assembly. Background Technology

[0002] Horizontal screw centrifuges, as highly efficient solid-liquid separation equipment, play a vital role in various fields such as environmental protection, chemical industry, and food processing. Their working principle is based on centrifugal sedimentation technology, using a high-speed rotating drum to generate powerful centrifugal force, effectively separating solid particles from the liquid in the material. The internal design of the horizontal screw centrifuge is ingenious, with the rotating drum and screw conveyor working in tandem, which not only improves separation efficiency but also ensures stable operation of the equipment. Simultaneously, advanced variable frequency speed control technology allows for flexible adjustment of the speed according to the characteristics of different materials, achieving optimal separation results. Furthermore, the horizontal screw centrifuge is equipped with an intelligent control system that can monitor the equipment's operating status in real time, promptly detect and handle potential faults, and ensure the continuity and safety of the production process.

[0003] To further enhance the safety and durability of horizontal decanter centrifuges, the design of the protective cover is crucial. The protective cover is made of high-strength materials, effectively resisting vibrations and impacts generated during operation. Its rational structural design ensures sufficient strength and rigidity while facilitating equipment maintenance and repair.

[0004] Patent document CN204933734U discloses a positioning mechanism for the casing of a horizontal screw centrifuge. The key technical points of the mechanism are: it includes a frame, on which a rotating drum is rotatably mounted, and a casing hinged to the frame and covering the rotating drum. Positioning components for positioning the casing are provided on both sides of the rotating drum on the frame and the casing. By setting positioning components on the frame and the casing, the casing can be easily positioned during use, assisting in the positioning of the casing. Even after the hinges between the casing and the frame age or shake, the positioning components can position the casing in the required position, making it easy to fix the casing to the frame with bolts.

[0005] As in the prior art of the aforementioned patent, the horizontal screw centrifuge is equipped with a cover for protecting the internal devices. The cover is rotatably connected to the frame via a hinge assembly. When maintenance is required on the centrifuge inside the cover, the cover needs to be unlocked from the frame, and then the cover needs to be flipped over before the subsequent maintenance work can be carried out. However, due to the large size of the cover, flipping it over will also occupy a lot of space, which will cause inconvenience to the maintenance work. Secondly, although the cover can increase the protective performance of the centrifuge, it will reduce the heat dissipation performance of the centrifuge. The aforementioned cover does not have a heat dissipation component, so it will also affect the heat dissipation performance of the cover. Summary of the Invention

[0006] The purpose of this invention is to provide a horizontal screw centrifuge with a casing assembly to address the aforementioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a horizontal decanter centrifuge with a casing assembly, comprising a worktable, a horizontal decanter centrifuge body fixedly mounted on the top of the worktable, two arc-shaped through slots being opened on the top of the worktable, the two arc-shaped through slots being respectively opened on both sides of the horizontal decanter centrifuge body, a casing being provided on the outside of the horizontal decanter centrifuge body, the casing being semi-circular in shape, the casing sliding relative to the two arc-shaped through slots when rotating around its own central axis, toothed rings being fixedly mounted on both ends of the casing, the two toothed rings being slidably connected to the two arc-shaped through slots, a drive assembly for driving the toothed rings to rotate being provided at the bottom of the worktable, and a heat dissipation assembly being provided on the casing.

[0008] As a further description of the above technical solution: the drive component includes a motor, which is disposed at the bottom of the worktable. The output end of the motor is connected to a rotating shaft, and two gears are fixedly installed on the rotating shaft. The two gears mesh with two gear rings.

[0009] As a further description of the above technical solution: the heat dissipation component includes a plurality of heat dissipation grooves formed on the surface of the cover, and a dustproof mesh is provided inside the plurality of heat dissipation grooves.

[0010] As a further description of the above technical solution: a cleaning cylinder is fixedly installed on the rotating shaft, and multiple cleaning brushes are fixedly installed on the peripheral wall of the cleaning cylinder.

[0011] As a further description of the above technical solution: two support columns are fixedly installed at the bottom of the workbench, one end of the motor is fixedly connected to one of the support columns, and the end of the rotating shaft away from the motor is rotatably connected to the other support column.

[0012] As a further description of the above technical solution: two reinforcing plates are fixedly installed at the bottom of the workbench, and the rotating shaft passes through the two reinforcing plates and is rotatably connected to the reinforcing plates.

[0013] As a further description of the above technical solution: two rubber pads are fixedly installed at the bottom ends of the two support columns.

[0014] As a further description of the above technical solution: the surface of the cover is provided with a heat dissipation coating.

[0015] This invention provides a horizontal decanter centrifuge with a casing assembly. It offers the following advantages: When maintenance is required on the centrifuge body inside the casing, the casing can be rotated by rotating the two toothed rings via a drive assembly. During rotation, the casing slides against the arc-shaped through-slot, allowing it to rotate below the worktable. This allows workers to easily inspect the centrifuge on the worktable. Furthermore, the casing is neatly stored below the worktable, minimizing space occupation and minimizing disruption to maintenance work. Additionally, the heat dissipation grooves on top of the casing effectively dissipate heat generated during centrifuge operation, ensuring the device's heat dissipation performance.

[0016] 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.

[0017] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description
