Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a shockproof base for a horizontal screw centrifuge. Background Technology

[0002] Horizontal decanter centrifuges, as highly efficient solid-liquid separation equipment, occupy an important position in many industrial fields such as chemical, environmental protection, food, and pharmaceutical industries due to their advantages of continuous operation, high separation efficiency, and high degree of automation. However, traditional anti-vibration bases for horizontal decanter centrifuges have several shortcomings in design and use. Structurally, many bases adopt traditional fixed structures, resulting in a high center of gravity and a lack of flexible adjustment mechanisms, making it difficult to adapt to the installation requirements of centrifuges of different sizes. When installing centrifuges of different lengths or sizes, it is often necessary to redesign or modify the base, making the installation process cumbersome, inefficient, and increasing equipment replacement and maintenance costs. Publication No. CN207138123U discloses a split base for a horizontal screw discharge sedimentation centrifuge, relating to the field of centrifuge technology. The base includes a main base, an auxiliary base, and a corner base. The auxiliary base and corner base are respectively installed on opposite sides of the bottom of the main base. The end of the auxiliary base facing away from the corner base extends out of the main base. A drum bearing housing is installed on the main base, and a drum bearing is installed on the drum bearing housing. A main motor and an auxiliary motor are installed on the auxiliary base. The main motor and auxiliary motor are connected to the drum bearing via differentials, which are installed on either the main base or the auxiliary base. While this device allows for a split and detachable base, reducing installation difficulty, the fixed-size base cannot accommodate centrifuges of various sizes. It requires specific or fixed matching mounting frames, leading to decreased installation adaptability and affecting installation and usage efficiency. Improvements are needed. Utility Model Content

Here, the two ends of screw 3 are rotatably connected to the inside of base plate 1 through deep groove ball bearings to ensure the smooth rotation of screw 3.

[0024] Example 2

[0025] Please see Figure 1 , Figure 4-5The damping mechanism 11 includes a base column 110, a lower damping seat 111 threadedly connected to the surface of the base column 110, an elastic arc plate 112 fixedly connected to the surface of the lower damping seat 111, an upper damping seat 113 fixedly connected to one end of the elastic arc plate 112, a threaded column 114 fixedly connected to the upper surface of the upper damping seat 113, a rotating cylinder 115 threadedly connected to the surface of the threaded column 114, and a top block 116 rotatably connected to one end of the rotating cylinder 115.

The interior of the upper shock absorber 113 has a sliding hole that matches the diameter of the base column 110. Here, the interior of the upper shock absorber 113 is slidably connected to the surface of the base column 110 through a sliding hole. This sliding connection, together with the elastic arc plate 112, allows the upper shock absorber 113 to move up and down on the base column 110. At the same time, the deformation of the elastic arc plate 112 absorbs vibration energy. The top block 116 is a U-shaped groove rectangular block, which is designed to better contact the damped component. The rubber pad on the surface can further enhance the damping effect and protection. The sliding hole inside the upper shock absorber 113 matches the diameter of the base column 110, ensuring that the upper shock absorber 113 remains stable during sliding and does not wobble.

[0026] Working Principle: When installing a horizontal screw centrifuge, motor A2 is started first. The output of motor A2 drives screw 3 to rotate via a coupling. The rotation of screw 3 causes the mounting bracket 4 to move smoothly along the axial direction of screw 3 on the base plate 1. In this way, the position of the mounting bracket 4 can be flexibly adjusted according to the length of the centrifuge body 17, so that the mounting bracket 4 is in a suitable installation range. After the mounting bracket 4 is moved to the appropriate position, the operator rotates the lead screw handle 5. The lead screw handle 5 is rotatably connected to the clamping block A6 through a bearing. When the lead screw handle 5 is rotated, the clamping block A6 will slide along the slide rod A7 inside the mounting bracket 4. At the same time, cylinder 8 is started. The output of cylinder 8 pushes clamping block B9 through a flange. Both clamping blocks A6 and B9 are U-shaped rectangular blocks with high-elasticity rubber pads with anti-slip texture on their surfaces. As clamping blocks A6 and B9 move, they can firmly clamp centrifuge bodies 17 of different sizes, realizing rapid fixation of the centrifuge, enhancing the adaptability of the base to centrifuges of different specifications, and improving installation and fixation efficiency. After the centrifuge is installed and secured, start motor B13. Motor B13 can adjust its speed to output appropriate power according to the actual working scenario and material characteristics, thereby driving the internal mechanism of the centrifuge body 17 to rotate at high speed for material separation and other tasks. During the operation of the centrifuge body 17, strong vibrations will occur. When the centrifuge vibrates, the vibration is transmitted to the top block 116, which then transmits pressure to the upper shock absorber 113, the elastic arc plate 112, and the lower shock absorber 111. Under pressure, the upper shock absorber 113 slides up and down along the bottom column 110, while the elastic arc plate 112 undergoes elastic deformation, absorbing vibration energy through elastic deformation, thus effectively buffering and reducing centrifuge vibration. If it is necessary to adjust the contact and damping effect between the damping mechanism 11 and the centrifuge body 17 of different sizes, the rotating drum 115 can be rotated. The rotating drum 115 is threadedly connected to the screw 114. When the rotating drum 115 is rotated, it will move up and down along the screw 114. Since one end of the rotating drum 115 is rotatably connected to the top block 116 through a bearing, it drives the top block 116 to move up and down, so that the top block 116 can fit tightly against the surface of the centrifuge body 17 of different sizes, ensuring that the vibration can be effectively transmitted to the damping mechanism 11 for absorption, further optimizing the damping effect and ensuring the stable operation of the horizontal screw centrifuge.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
