Description

Technical Field

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

[0002] The horizontal screw discharge centrifuge is a highly efficient solid-liquid separation device. Its core principle is to generate strong centrifugal force through the high-speed rotating drum, causing solid particles to settle on the inner wall of the drum, while the liquid phase forms an inner liquid ring. The speed difference between the screw conveyor and the drum pushes the solid phase towards the slag discharge port, thus achieving continuous separation.

[0003] With technological advancements, modern horizontal screw centrifuges have adopted advanced dynamic balancing technology, high-quality materials, and intelligent control systems. This has not only improved separation efficiency and reduced energy consumption but also enabled fully automated operation. Furthermore, the diverse designs in terms of materials, configuration, and feeding methods have further enhanced their adaptability and application range, making them an important piece of equipment in the field of solid-liquid separation.

[0004] Existing horizontal screw discharge centrifuges generate a lot of noise from their motors during operation. Long-term exposure to the high noise environment produced by the motor can easily damage the hearing of operators and may also cause negative emotions such as irritability and anxiety, leading to a significant decrease in work efficiency and quality. Moreover, the motors of existing horizontal screw discharge centrifuges are generally exposed, making it difficult to suppress the noise generated by the motor. Utility Model Content

[0023] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figure 1-6 A noise reduction mechanism for a horizontal screw discharge centrifuge includes a horizontal centrifuge body 1. A mounting plate 2 is fixedly connected to one end of the centrifuge body 1. A motor 3 is fixedly mounted on the mounting plate 2. A soundproof cover 4 is fixedly mounted on the mounting plate 2. Sealing strips 5 are provided at one end of the centrifuge body and at the top of the mounting plate 2. The edge of the soundproof cover 4 contacts the two sealing strips 5. This device provides a soundproof cover 4 to seal the motor 3 of the horizontal centrifuge body 1 inside the soundproof cover 4, thereby isolating the motor 3 and reducing the noise generated by the motor 3 during operation. Furthermore, the tight contact between the sealing strips 5 and the edge of the soundproof cover 4 reduces noise dissipation at the connection between the horizontal centrifuge body 1 and the soundproof cover 4, further improving the noise reduction effect.

[0025] As a preferred technical solution in this embodiment, a clamping strip 6 is slidably installed on the mounting plate 2, and a connecting strip 7 is fixedly installed on both sides of the inner wall of the soundproof cover 4. The connecting strip 7 is engaged with the clamping strip 6, and the connecting strip 7 is located below the clamping strip 6. By pressing down the clamping strip 6, the sealing strip 5 on the mounting plate 2 is brought into close contact with the bottom edge of the soundproof cover 4, thereby increasing the sealing performance and improving the noise reduction effect.

[0026] As a preferred embodiment, a plurality of drive plates 8 are fixedly installed at the bottom of the clamping strip 6, and each of the drive plates 8 has a drive groove 9. An adjusting screw 10 is rotatably installed inside the mounting plate 2, and a plurality of connecting blocks 11 are threadedly connected to the adjusting screw 10. The plurality of connecting blocks 11 are slidably installed inside the mounting plate 2, and connecting posts 12 are fixedly installed on the side wall of the connecting blocks 11. The plurality of connecting posts 12 are slidably disposed inside the plurality of drive grooves 9. When installing the soundproof cover 4 in this device, the connecting strip 7 is first positioned in the clamping strip 6. Next, slide the soundproof cover 4 to initially install the soundproof cover 4 onto the horizontal centrifuge body 1. Then, rotate the adjusting screw 10, and through threaded transmission, move multiple connecting blocks 11 toward one end of the horizontal centrifuge. The drive groove 9 of this device is inclined and the end near the horizontal centrifuge body 1 is set as the highest point. During the movement of the connecting blocks 11, the positions of the connecting blocks 11 and the connecting column 12 remain unchanged, causing the drive plate 8 and the pressing strip 6 to press down, thereby applying downward pressure to the connecting strip 7, so that the sealing strip 5 on the mounting plate 2 is in close contact with the bottom edge of the soundproof cover 4.

[0027] As a preferred technical solution in this embodiment, the mounting plate 2 is provided with an extrusion plate 13, which contacts the side of the soundproof cover 4 away from the horizontal centrifuge body 1. The extrusion plate 13 extrudes the soundproof cover 4, so that the sealing strip 5 on the horizontal centrifuge body 1 is in close contact with the side edge of the soundproof cover 4, thereby increasing the sealing performance and improving the noise reduction effect.

[0028] As a preferred technical solution in this embodiment, the end of the adjusting screw 10 near the extrusion plate 13 is threadedly connected to a connecting plate 14. The connecting plate 14 is rotatably connected to the extrusion plate 13, and a connecting frame 15 is fixedly connected to the connecting plate 14. The connecting frame 15 is slidably connected to the inside of the mounting plate 2. When the adjusting screw 10 is rotated, the extrusion plate 13 moves accordingly and extrudes the soundproof cover 4, so that the sealing strip 5 on the horizontal centrifuge body 1 is in close contact with the side edge of the soundproof cover 4.

[0029] As a preferred technical solution of this embodiment, the mounting plate 2 is provided with a storage groove 16, and the top of the storage groove 16 is provided with a groove 17; through the rotatable connection between the extrusion piece 13 and the connecting piece 14, the extrusion piece 13 can be rotatably inserted into the storage groove 16, which facilitates the disassembly of the soundproof cover 4, hides the extrusion piece 13, and avoids the extrusion piece 13 from blocking the disassembly of the soundproof cover 4. The groove 17 provided at the top of the storage groove 16 facilitates the lifting of the extrusion piece 13 from the storage groove 16.

[0030] As a preferred technical solution in this embodiment, a limiting frame 18 is fixedly installed on one end of the horizontal centrifuge body 1 near the mounting plate 2, and the edge of the soundproof cover 4 is engaged with the limiting frame 18; the limiting frame 18 facilitates the installation of the soundproof cover 4.

[0031] As a preferred technical solution in this embodiment, a plurality of heat dissipation fins 19 are fixedly installed on the top of the soundproof cover 4; the heat dissipation fins 19 promote heat exchange inside and outside the soundproof cover 4, so as to dissipate the heat generated when the motor 3 is running.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
