Description

Technical Field

[0001] This utility model relates to the technical field of centrifuge protective structure, specifically a ventilation and noise reduction structure for a centrifuge. Background Technology

[0002] Centrifuges are a common piece of equipment in chemical laboratories, mainly used to physically separate multiphase miscible substances. Through high-speed centrifugal force, one phase is thrown to the bottom, while the liquid phase remains at the top. After centrifugation, the liquid phase at the top can be directly poured out. Generally speaking, centrifuges need to rotate at high speed when working, so they are often accompanied by a lot of noise, which is a great annoyance to the experimenter.

[0003] In the prior art, patent CN208599965U discloses a noise-reducing centrifuge, including a casing, a top cover, an inner liner, a motor, a rotor, and a shock absorber. The top cover is connected to the casing, and the inner liner is disposed inside the casing. A first through hole is opened at the bottom of the inner liner. The shock absorber is installed at the bottom inside the casing and includes a spring and a tray. One end of the spring is connected to the casing, and the other end is connected to the tray. A rubber sleeve is provided on the surface of the spring. The motor is disposed on the tray, and one end of the motor passes through the first through hole and is connected to the rotor, which is located inside the inner liner. By providing a rubber sleeve on the surface of the spring of the shock absorber, the swaying of the spring can be hindered, reducing the swaying amplitude of the motor, thereby reducing the noise generated by the centrifuge during operation from the source. The above solution improves some of the problems of the prior art to a certain extent. However, for centrifuges, the motor generates huge noise and a lot of heat when running at high speed. Therefore, those skilled in the art have proposed a ventilation and noise reduction structure for centrifuges to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a ventilation and noise reduction structure for a centrifuge to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A ventilation and noise reduction structure for a centrifuge includes a housing with a door at the front end and a base plate on the inner bottom surface of the housing. The centrifuge body is placed on the top of the base plate. Adjustment components are installed on both sides of the top of the base plate. A shock-absorbing seat is installed at one end of each adjustment component, with the bottom end of the shock-absorbing seat slidingly against the top of the base plate. A support rod is installed on the shock-absorbing seat, and a clamping plate is installed at the top of the support rod. The two clamping plates are used to clamp the outer wall of the centrifuge body. Air ducts are installed on both sides of the housing, and fans are installed inside the air ducts. A filter plate is installed at the outer end of the air ducts. A sound insulation layer is installed on the inner wall of the housing and the door, and several loudspeakers are installed on the inner wall of the sound insulation layer, evenly distributed around the periphery of the centrifuge body.

[0007] As a further embodiment of this utility model: the adjustment assembly includes a vertical plate and a threaded rod. The bottom end of the vertical plate is fixedly connected to the top end of the base plate. A threaded sleeve is provided in the middle of the vertical plate. The middle part of the threaded rod is threadedly connected to the threaded sleeve. A throttle handle is connected to one end of the threaded rod away from the centrifuge body. A connecting sleeve is rotatably connected to the other end of the threaded rod. The end of the connecting sleeve is fixedly connected to the outer wall of the shock-absorbing seat.

[0008] As a further embodiment of this utility model: a plurality of damping springs are evenly distributed around the inner wall of the shock absorber seat; the bottom end of the support rod slides against the inner bottom surface of the shock absorber seat; and the end of the damping spring near the center of the shock absorber seat is fixedly connected to the bottom outer wall of the support rod.

[0009] As a further embodiment of this utility model: the clamping plate is detachably installed on the top of the support rod, the shape and size of the clamping plate correspond to the outer dimensions of the centrifuge body, and the inner circumference of the clamping plate is provided with an elastic layer.

[0010] As a further improvement of this utility model, a diffuser is connected to one end of the air duct near the centrifuge body.

[0011] This utility model has the following advantages: The structure uses adjusting components, shock-absorbing seats, support rods, and clamping plates to clamp the centrifuge body, facilitating the installation, fixing, and disassembly of the centrifuge body. The shock-absorbing seats provide vibration damping for the centrifuge body during operation. Several speakers generate reverse sound waves equal to the noise of the centrifuge body, neutralizing the noise and achieving a noise reduction effect. Combined with the sound insulation layer on the inner wall of the chamber, the noise reduction effect is significantly improved. The installation of air ducts provides ventilation and heat dissipation for the periphery of the centrifuge body, resulting in better performance. Attached Figure Description

[0020] Please see Figure 2 , Figure 3The adjusting assembly 7 includes a vertical plate 12 and a threaded rod 14. The bottom end of the vertical plate 12 is fixedly connected to the top end of the base plate 4. A threaded sleeve 13 is provided in the middle of the vertical plate 12. The middle part of the threaded rod 14 is threadedly connected to the threaded sleeve 13. A throttle 15 is connected to one end of the threaded rod 14 away from the centrifuge body 25. A connecting sleeve 16 is rotatably connected to the other end of the threaded rod 14. The end of the connecting sleeve 16 is fixedly connected to the outer wall of the shock absorber 8.

[0021] Please see Figures 2 to 4 The inner wall of the shock absorber 8 is evenly connected with several shock-absorbing damping springs 17. The bottom end of the support rod 9 slides against the inner bottom surface of the shock absorber 8. The bottom end of the support rod 9 is widened to make the movement of the support rod 9 more stable. The top of the support rod 9 is made into a right angle. The end of the shock-absorbing damping spring 17 near the center of the shock absorber 8 is fixedly connected to the bottom outer wall of the support rod 9. The top of the shock absorber 8 is provided with a movable groove 18 for the support rod 9 to move.

[0022] Example 2: See Figure 2 , Figure 5 Based on Embodiment 1, the clamping plate 10 is detachably installed on the top of the support rod 9. The shape and size of the clamping plate 10 correspond to the outer dimensions of the centrifuge body 25. An elastic layer 11 is provided on the inner circumference of the clamping plate 10.

[0023] Please see Figure 1 , 2 The end of the air duct 19 near the centrifuge body 25 is connected to a diffuser 22, which enhances the ventilation effect inside the box 1.

A shock-absorbing pad 5 is provided between the bottom end of the bottom plate 4 and the inner bottom surface of the box 1. A transparent observation window 3 is provided on the box door 2.

[0024] Working principle: When in use, the centrifuge body 25 is placed at the top center of the base plate 4. Turning the handle 15 drives the threaded rod 14 to rotate and move, thereby driving the two shock-absorbing seats 8 to move closer to each other. Then, the support rod 9 drives the two clamping plates 10 to move closer to each other to clamp and fix the outer wall of the centrifuge body 25. When the centrifuge body 25 is in use, it will drive the clamping plates 10 to vibrate. The clamping plates 10 drive the support rod 9 to vibrate. The bottom of the support rod 9 compresses the shock-absorbing damping spring 17 to dampen the vibration of the support rod 9 and the clamping plates 10, thereby damping the centrifuge body 25. The fans 20 in the two air ducts 19 ventilate and dissipate heat in the inner cavity of the box 1. The speaker 24 generates a reverse sound wave equal to the noise of the centrifuge body 25 to neutralize the noise. The sound insulation layer 23 is used to reduce the noise in the inner cavity of the box 1.
