Abstract
Description
Technical Field
[0001] This utility model relates to the field of horizontal screw centrifuge technology, and in particular to a feeding structure for a horizontal screw centrifuge. Background Technology
[0002] Horizontal screw centrifuges, as highly efficient solid-liquid separation equipment, occupy an important position in various industries such as chemical, environmental protection, food, and pharmaceutical. They effectively separate solid particles from liquid in suspension through centrifugal force generated by high-speed rotation. As a key link in the solid-liquid treatment process, the stability and efficiency of its feeding structure have a decisive impact on the overall separation effect and operational safety of the centrifuge. In particular, during the centrifuge feeding process, the stability of the connection between the feed pipe and the discharge port of the storage equipment, as well as the smoothness of material transport, are crucial to ensuring the efficient operation of the centrifuge.
[0003] Currently, there is an automatic feeding device for a three-legged centrifuge on the market. This device uses a flexible feeding tube with a feeding valve to control the feeding. However, this type of feeding tube lacks a positioning support device at the feeding interface. Vibrations generated during machine operation, under prolonged use, can cause instability at the interface, leading to gaps and material leakage. This not only wastes material but may also pollute the production environment. A centrifuge feeding tube (application number 200580024151.X) improves the stability of the connection by incorporating a support component into the feeding tube.
[0004] However, the support component in the aforementioned patent only has a fixing function and cannot realize the lifting and moving of the feed pipe. Since the horizontal screw centrifuge needs to be connected with various different storage devices through the feed pipe, and the outlet height of these storage devices is also different, different feed pipes and mechanisms need to be prepared for connection and assembly in order to achieve connection. This not only increases the difficulty of implementation, but also makes the support structure unstable and difficult to disassemble, which brings inconvenience to maintenance and replacement.
[0005] Therefore, given the numerous shortcomings of existing technologies, we urgently need a feeding structure for a horizontal screw centrifuge to solve this problem. This feeding structure should be able to achieve stable support and vertical movement of the feed pipe, facilitating connection with the discharge ports of storage devices at different heights.

The two positioning plates are symmetrically arranged at the top and bottom of the feeding pipe and are connected by a positioning structure. A lifting mechanism is provided at the top of the bottom plate and is connected to the bottom of the positioning plate at the bottom position.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] Example 1
[0025] Please see Figure 1-5 As shown, the feeding structure of a horizontal screw centrifuge in this embodiment includes a horizontal screw centrifuge 5, a feeding pipe 3, and two positioning plates 4;
[0026] Horizontal screw centrifuge 5: As the main equipment for solid-liquid separation, it is responsible for centrifugally separating the material introduced by the feed pipe 3.
[0027] Feed pipe 3: Serves as a material transfer channel, guiding the material in the storage equipment to the horizontal screw centrifuge 5 for processing.
[0028] Positioning plates 4 (two): symmetrically set at the top and bottom of the feed pipe 3, and tightly connected by a positioning structure to ensure the stability of the feed pipe 3 in the vertical direction.
[0029] Base plate 1: Located on one side of the bottom of the feed pipe 3, providing a stable installation base for the subsequent lifting mechanism.
[0030] Lifting mechanism: Connected to the bottom of the positioning plate 4 at the bottom position, the height of the feed pipe 3 can be adjusted according to actual needs, so that the horizontal screw centrifuge 5 can be connected to the discharge port of storage equipment of different heights.
[0031] A base plate 1 is provided on one side of the bottom of the feed pipe 3. Two positioning plates 4 are symmetrically arranged at the top and bottom of the feed pipe 3, and the two positioning plates 4 are connected by a positioning structure. A lifting mechanism is provided at the top of the base plate 1, and the lifting mechanism is connected to the bottom of the positioning plate 4 at the bottom position.
[0032] Example 2
[0033] Please see Figure 1-5 As shown in the figure, the feeding structure of a horizontal decanter centrifuge in this embodiment has a V-shaped positioning plate 4, with side plates 10 connected to both sides of the two positioning plates 4. Specifically, the V-shaped positioning plate 4 and the side plates 10 connected to both sides of the two positioning plates 4 enhance the support stability of the positioning plate 4 for the feed pipe 3. During the operation of the horizontal decanter centrifuge 5, the V-shaped positioning plate 4 can better fit the outer surface of the feed pipe 3, providing uniform support force. At the same time, the connection of the side plates 10 further strengthens the structure of the positioning plate 4, preventing it from deforming or being damaged under long-term stress. This design significantly improves the vertical stability of the feed pipe 3, effectively avoiding displacement or shaking caused by vibration or external impact, and achieving the effect of improving the overall stability of the feeding structure.
[0034] Each pair of adjacent side plates 10 is connected by several positioning screws 9. Specifically, this connection further reinforces the support frame formed by the positioning plate 4 and the side plates 10. The tight connection of the positioning screws 9 makes the side plates 10 form a stable whole, effectively resisting the lateral force from the feed pipe 3. During the operation of the horizontal screw centrifuge 5, this design prevents the support frame from loosening or deforming, ensuring the long-term stable operation of the feed pipe 3. This achieves the effect of improving the structural strength and stability of the support frame.
[0035] Example 3
[0036] Please see Figure 1-5 As shown in the figure, the feeding structure of a horizontal screw centrifuge in this embodiment includes a top plate 2 on the top of a base plate 1. The top plate 2 is connected to the top of the base plate 1 via several support rods 7. Specifically, the top plate 2 on the top of the base plate 1 and the connection between the top plate 2 and the top of the base plate 1 via several support rods 7 provide a stable mounting frame for the lifting mechanism. The cooperation between the top plate 2 and the support rods 7 not only enhances the load-bearing capacity of the base plate 1 but also provides accurate guidance for the movement of the lifting mechanism. During the operation of the lifting mechanism, the top plate 2 serves as a fixed reference point, ensuring the smoothness and accuracy of the lifting process. This design achieves the effect of improving the operational stability and reliability of the lifting mechanism, providing a strong guarantee for the precise adjustment of the feed pipe 3.
[0037] The lifting mechanism includes a drive motor 6 mounted on the top of the base plate 1 and a rotating screw sleeve 8 that rotatably penetrates the top plate 2 at one end. The output shaft of the drive motor 6 is connected to the bottom end of the rotating screw sleeve 8. A lifting screw 11, one end of which is rotatably connected to the bottom of the positioning plate 4, is threaded inside the rotating screw sleeve 8. Vertical guide structures are provided on both sides of the lifting screw 11, one end of which is connected to the positioning plate 4, and the other end is slidably connected to the top plate 2. Specifically, the lifting mechanism, including the drive motor 6 mounted on the top of the base plate 1 and the rotating screw sleeve 8 that rotatably penetrates the top plate 2 at one end, and the drive motor 6's output shaft connected to the bottom end of the rotating screw sleeve 8, and the rotating screw sleeve 8's internal threaded connection to the lifting screw 11 that rotatably connects to the bottom of the positioning plate 4, achieves precise lifting of the feed pipe 3. The drive motor 6 provides power, and through the threaded transmission of the rotating screw sleeve 8 and the lifting screw 11, converts rotational motion into linear motion, thereby driving the positioning plate 4 and the feed pipe 3 to move up and down. This design achieves precise height adjustment of the feed pipe 3, meeting the docking requirements of the horizontal screw centrifuge 5 with the discharge ports of storage devices at different heights.
[0038] The vertical guide structure includes a guide rod 12, one end of which is connected to the bottom of the positioning plate 4, and the other end slides through the top plate 2. Specifically, the vertical guide structure, including the guide rod 12, and the arrangement of one end of the guide rod 12 connected to the bottom of the positioning plate 4 and the other end sliding through the top plate 2, provides additional guidance and support for the lifting process. The guide rod 12 maintains vertical sliding during lifting, ensuring the linear movement trajectory of the positioning plate 4 and the feed pipe 3. Simultaneously, the sliding connection between the guide rod 12 and the top plate 2 reduces frictional resistance during lifting, improving lifting efficiency. This design enhances the stability and accuracy of the lifting process, providing strong support for the rapid and accurate docking of the feed pipe 3.
[0039] This solution includes the following workflow:
[0040] The feed pipe 3 serves as a material transfer channel, and a base plate 1 is installed on one side of its bottom, providing a stable installation foundation for the subsequent lifting mechanism. Two positioning plates 4 are symmetrically arranged at the top and bottom of the feed pipe 3, and they are tightly connected by a positioning structure to ensure the initial stability of the feed pipe 3 in the vertical direction.
[0041] Furthermore, the positioning plate 4 is designed in a V-shape, which allows it to better fit the outer surface of the feed tube 3 and provide uniform support. Simultaneously, side plates 10 are connected to both sides of the two positioning plates 4, further reinforcing the structure of the positioning plates 4 and preventing deformation or damage under long-term stress. The combination of these structures significantly improves the vertical stability of the feed tube 3, effectively preventing displacement or shaking caused by vibration or external impact.
[0042] A top plate 2 is provided on the top of the base plate 1. The top plate 2 is connected to the top of the base plate 1 by several support rods 7, providing a stable mounting frame for the lifting mechanism. The cooperation between the top plate 2 and the support rods 7 not only enhances the load-bearing capacity of the base plate 1, but also provides accurate guidance for the movement of the lifting mechanism. When the lifting mechanism is working, the top plate 2 serves as a fixed reference point, ensuring the stability and accuracy of the lifting process.
[0043] Each pair of adjacent side plates 10 is connected by several positioning screws 9. This arrangement further reinforces the support frame composed of the positioning plate 4 and the side plates 10. The tight connection of the positioning screws 9 makes the side plates 10 form a stable whole, effectively resisting the lateral force from the feed pipe 3, preventing the support frame from loosening or deforming, and ensuring the long-term stable operation of the feed pipe 3.
[0044] The lifting mechanism is the core component of this feeding structure, comprising a drive motor 6 mounted on the top of the base plate 1 and a rotating screw sleeve 8 that rotates through the top plate 2 at one end. The output shaft of the drive motor 6 is connected to the bottom end of the rotating screw sleeve 8, and a lifting screw 11 is internally threaded into the rotating screw sleeve 8, with one end rotatably connected to the bottom of the positioning plate 4. When the drive motor 6 starts, its output shaft drives the rotating screw sleeve 8 to rotate. Through the threaded transmission principle, the lifting screw 11 moves up and down within the rotating screw sleeve 8, thereby driving the positioning plate 4 and the feed pipe 3 to move up and down. This design enables precise adjustment of the height of the feed pipe 3, meeting the docking requirements of the horizontal screw centrifuge 5 with the discharge ports of storage devices at different heights.
[0045] To further enhance the smoothness and accuracy of the lifting process, vertical guide structures are provided on both sides of the lifting screw 11. Each vertical guide structure includes a guide rod 12, one end of which is connected to the bottom of the positioning plate 4, and the other end slides through the top plate 2. During the lifting process, the guide rod 12 maintains vertical sliding, ensuring the linear movement trajectory of the positioning plate 4 and the feed pipe 3. Simultaneously, the sliding connection between the guide rod 12 and the top plate 2 reduces frictional resistance during lifting, improving lifting efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
