[0003] As disclosed in the utility model with the application number 202120594195.2, especially relates to a horizontal screw centrifuge. The utility model performs secondary treatment on the liquid that needs to be centrifuged twice or multiple times through a recovery system, eliminating manual operation, improving work efficiency, and the pre-filter device in the utility model can filter larger particles in the liquid, minimizing the damage to the horizontal screw sedimentation centrifuge caused by the liquid to be treated.

[0004] The similar applications currently still have deficiencies:

[0022] Embodiment 1

[0023] As Figures 1-3 shown, this embodiment provides a low-noise horizontal spiral centrifuge, including a support plate 1. A centrifuge body 2 is installed on the top of the support plate 1. Support columns 3 are evenly arranged on the top of the support plate 1. The bottoms of the support columns 3 are all fixed with mounting plates 4. Mounting blocks 5 are symmetrically installed on the mounting plates 4, and the bottom ends of the mounting blocks 5 penetrate and extend into the interior of the mounting plates 4. The outer sides of the mounting plates 4 are threadedly connected with mounting tubes 6. A buffer rod 7 is fixed to the bottom of the mounting plate 4. A spring 8 is sleeved on the outer side of the buffer rod 7. A limit ring 13 is fixed to the bottom end of the buffer rod 7. The bottom of the limit ring 13 is movably connected with a buffer tube 9. A fixing plate 10 is fixed to the bottom of the buffer tube 9. A movable plate 11 is fixed to one side of the mounting plate 4. A support rod 12 is threadedly connected to the movable plate 11. A protective shell 14 is arranged on the top of the support plate 1, and the protective shell 14 is sleeved on the outer side of the centrifuge body 2. A first sound insulation pad 15 is fixed inside the protective shell 14. A second sound insulation pad 16 is fixed inside the first sound insulation pad 15. A sound absorption layer 17 is fixed inside the second sound insulation pad 16. Limit plates 18 are fixed to both sides of the protective shell 14.

[0024] Through the combined use of the support plate 1, the centrifuge body 2, the support column 3, the mounting plate 4, the mounting block 5, the mounting tube 6, the buffer rod 7, the spring 8, the buffer tube 9, the fixing plate 10, the movable plate 11, the support rod 12 and the limiting ring 13, during the operation of the centrifuge body 2, the support plate 1 is driven to vibrate, causing the vibration potential energy to be transmitted to the support column 3 and then to the spring 8, which plays a role in absorbing the vibration potential energy. Rotate the support rod 12 downward until the bottom end of the support rod 12 abuts against the top of the fixing plate 10, so that the bottom end of the buffer rod 7 disengages from the inside of the buffer tube 9. Then, rotate the mounting tube 6 outside the mounting block 5 upward, and the buffer rod 7 and the spring 8 can be removed from between the mounting plate 4 and the buffer tube 9. This can weaken the vibration potential energy generated during the operation of the centrifuge body 2, not only achieving the purpose of reducing vibration noise, but also protecting the components inside the centrifuge body 2, and facilitating the replacement of the fatigued and damaged spring 8, thereby improving the practicability of this low-noise horizontal spiral centrifuge; through the combined use of the protective shell 14, the first sound insulation pad 15, the second sound insulation pad 16 and the sound absorption layer 17, the noise generated by the centrifuge body 2 is gradually absorbed by the sound absorption layer 17, the second sound insulation pad 16 and the protective shell 14, playing a role in reducing the noise, and further reducing the noise of the low-noise horizontal spiral centrifuge itself.

[0025] Embodiment 2

[0026] In this embodiment, as Figures 1-3 shown, insertion rods 19 are rotatably connected to both sides of the support plate 1, and a U-shaped plate 20 is threadedly connected to the outside of the insertion rods 19.

[0027] Through the combined use of the limiting plate 18, the insertion rods 19 and the U-shaped plate 20, rotate the U-shaped plate 20 to both sides respectively, so that the insertion rods 19 outside the U-shaped plate 20 move to both sides and disengage from the outside of the limiting plate 18 and the support plate 1, and then the protective shell 14 can be removed from the support plate 1, facilitating the maintenance work of the centrifuge body 2, and thus facilitating the use by the staff.

[0028] In this embodiment, a turning handle is fixed to the top of the support rod 12, and an anti-slip layer is provided on the outside of the turning handle.

[0029] Through the turning handle and the anti-slip layer, the operability of the support rod 12 is improved, facilitating the use by people.

[0030] In this embodiment, a protective ring is fixed to the outside of the mounting tube 6, and the protective ring is a rubber protective ring.

[0031] Through the setting of the rubber anti-slip ring, the rotation of the mounting tube 6 is facilitated, and the use is more labor-saving and convenient.

[0032] In this embodiment, a reinforcing pad is provided inside the insertion rod 19, and anti-slip particles are provided inside the reinforcing pad.

[0033] The friction on the outer sides of the limiting plate 18 and the support plate 1 is increased through the settings of the reinforcement pads and the anti-slip particles, thereby improving the reinforcement effect.

[0034] As described above, it is only a further embodiment 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 scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent replacements or changes, and all belong to the protection scope of the present utility model.
