Description

Technical Field

[0001] The utility model relates to the field of centrifuges, and particularly to a centrifuge with liquid-solid separation function. Background Technique

[0002] A centrifuge is a device that separates substances with different densities in a mixture by using centrifugal force. Its working principle is based on the centrifugal force generated when an object rotates. This centrifugal force is proportional to the angular velocity of rotation, the mass of the object, and the radius of rotation. In a centrifuge, through the powerful centrifugal force generated by high-speed rotation, substances with different weights can be subjected to different forces during rotation, so that solids and liquids are separated into different containers.

[0003] When some existing centrifuges are in use, they usually drive the internal container to rotate through a motor. Through the centrifugal force generated by rotation, substances with different masses are separated by centrifugal force, and different substances are discharged and collected through an outlet. After use, the inside needs to be cleaned. After cleaning, disinfectant needs to be used to disinfect the inside. Due to the complexity of the centrifuge structure, such as areas like the rotor head and the corners of the cavity, there will be many dead corners, and it is difficult for the disinfectant to fully cover, resulting in incomplete disinfection. Therefore, a centrifuge with liquid-solid separation function is proposed to solve the above problems. Content of the Utility Model

After cleaning, disinfectant needs to be used to disinfect the inside. Due to the complexity of the centrifuge structure, such as areas like the rotor head and the corners of the cavity, there will be many dead corners, and it is difficult for the disinfectant to fully cover, resulting in incomplete disinfection. The utility model proposes a centrifuge with liquid-solid separation function.

[0025] The following will further elaborate on this application in conjunction with Figure 1 —5.

[0026] An embodiment of this application discloses a centrifuge with liquid-solid separation. Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 A centrifuge with liquid-solid separation includes a centrifuge body 1. An evaporation mechanism 2 is provided on one side of the centrifuge body 1, and a ventilation mechanism 3 is provided on the top of the centrifuge body 1;

[0027] The evaporation mechanism 2 includes a fixing frame 201. The fixing frame 201 is fixedly connected to one side of the centrifuge body 1. A heating device 202 is arranged inside the fixing frame 201. One side of the heating device 202 is electrically connected to a connecting wire 203. A heating tank 204 is fixedly connected inside the fixing frame 201. The top of the heating tank 204 is fixedly communicated with a corrugated expansion pipe 205. One end of the corrugated expansion pipe 205 is fixedly connected to a first magnetic attraction block 209. The top of the centrifuge body 1 is fixedly communicated with a first connecting pipe 206. A limiting groove 207 is opened at the top of the first connecting pipe 206. The inner wall of the limiting groove 207 is fixedly connected to a second magnetic attraction block 208. The second magnetic attraction block 208 is used in cooperation with the first magnetic attraction block 209. By setting the evaporation mechanism 2, when the disinfectant is evaporated at high temperature, steam will be generated. After the steam enters the centrifuge body 1, the centrifuge body 1 is a sealed space, which is conducive to the uniform diffusion of the steam to every corner inside the centrifuge body 1. Since the active ingredient in the steam has a strong sterilization ability, the steam can penetrate the cell wall of microorganisms and destroy the cell structure of microorganisms, resulting in the inactivation of microorganisms, thereby achieving the sterilization effect;

[0028] The ventilation mechanism 3 includes a second connecting pipe 301. The second connecting pipe 301 is fixedly connected to the top of the centrifuge body 1. A groove 302 is formed at the top of the second connecting pipe 301. A fixing block 303 is fixedly connected to the top of the second connecting pipe 301. A sealing cover 304 is arranged at the top of the second connecting pipe 301. One side of the sealing cover 304 contacts the surface of the fixing block 303. A rotating rod 305 is rotatably connected to the inner wall of the fixing block 303. Both ends of the rotating rod 305 penetrate to the outside of the fixing block 303 and are rotatably connected to one side of the sealing cover 304. A torsion spring 306 is sleeved on the surface of the rotating rod 305. One end of the torsion spring 306 is fixedly connected to the inner wall of the fixing block 303, and the other end of the torsion spring 306 is fixedly connected to the sealing cover 304. By providing the ventilation mechanism 3, the steam sealed in the inner cavity of the centrifuge body 1 can be effectively discharged. In order to maintain the continuous supply and uniform distribution of steam, new steam needs to continuously enter the centrifuge body 1. While the ventilation mechanism 3 discharges the old steam, it also provides space for the entry of new steam, ensuring that the centrifuge body 1 is always filled with high-concentration steam with a sterilizing effect, thereby improving the efficiency and effect of disinfection.

[0029] Refer to Figure 1 , a liquid adding pipe 4 is fixedly connected to the top of the heating tank 204. A lid 5 is threadedly connected to the top of the liquid adding pipe 4. By providing the liquid adding pipe 4, it is convenient for the user to add the disinfectant into the heating tank 204, enabling the quick and easy replenishment of the disinfectant when needed. The lid 5 can seal the liquid adding pipe 4 to prevent steam leakage.

[0030] Refer to Figure 1 , an elastic clamping block 6 is fixedly connected to one side of the centrifuge body 1. The elastic clamping block 6 is used in cooperation with the corrugated expansion pipe 205. By providing the elastic clamping block 6, when one end of the corrugated expansion pipe 205 needs to be removed from the top of the first connecting pipe 206, the corrugated expansion pipe 205 is inserted into the elastic clamping block 6, and the elastic force of the elastic clamping block 6 is used to clamp the corrugated expansion pipe 205, thereby achieving fixation.

[0031] Refer to Figure 1 and Figure 3 , a limiting block 7 is fixedly connected to one side of the corrugated expansion pipe 205. The limiting block 7 is used in cooperation with the elastic clamping block 6. By providing the limiting block 7, after the elastic clamping block 6 fixes the corrugated expansion pipe 205, it is convenient to clamp the limiting block 7 on the surface of the elastic clamping block 6 to prevent the corrugated expansion pipe 205 from falling off.

[0032] Refer to Figure 3 and Figure 4, a first valve 8 is fixedly connected inside the first connecting pipe 206, and a second valve 9 is fixedly connected inside the second connecting pipe 301. By providing the first valve 8 and the second connecting pipe 301, the first connecting pipe 206 and the second connecting pipe 301 can be closed when the centrifuge body 1 is operating, preventing external impurities or unsuitable liquids from entering the inside of the centrifuge body 1.

[0033] Refer to Figure 4 , a sealing ring 10 is fixedly connected to the bottom of the sealing cover 304, and one side of the sealing ring 10 is in contact with the inner wall of the groove 302. By providing the sealing ring 10, the connection between the sealing cover 304 and the second connecting pipe 301 can be sealed, preventing steam leakage inside during steam disinfection.

[0034] Refer to Figure 2 , a heat dissipation hole 11 is formed on one side of the fixing frame 201, and the number of the heat dissipation holes 11 is several. A communication groove 12 is formed on one side of the fixing frame 201, and the communication groove 12 is used in cooperation with the connecting line 203. By providing the heat dissipation hole 11, the air circulation inside the fixing frame 201 can be increased, preventing the internal temperature of the heating device 202 from being too high during operation. Through the communication groove 12, the connecting line 203 can be conveniently connected to external equipment to supply power to the heating device 202.

[0035] Working principle: After the centrifuge body 1 is cleaned, it is necessary to disinfect the inside. The user places the centrifuge body 1 in a ventilated position. By removing the lid 5 from the top of the liquid inlet pipe, the disinfectant is injected into the interior of the heating tank 204 through the liquid inlet pipe. Then, the connecting wire 203 is connected to an external device. The disinfectant in the heating tank 204 is heated by the heating device 202. The user opens the first valve 8 and the second valve 9, and then removes the corrugated expansion pipe 205 from the elastic clamping block 6. One end of the corrugated expansion pipe 205 is clamped in the limiting groove 207 of the first connecting pipe 206. The first magnetic block 209 connected by the corrugated expansion pipe 205 and the second magnetic block 208 in the limiting groove 207 will be connected, thereby connecting the corrugated expansion pipe 205 with the first connecting pipe 206 to facilitate the entry of steam. The heated disinfectant will evaporate, and the evaporated steam will gather in the heating tank 204. With the continuous heating of the heating device 202, the steam will enter the interior of the centrifuge body 1 through the corrugated expansion pipe 205 and the first connecting pipe 206. With the continuous injection of steam, the steam will enter every corner of the interior of the centrifuge body 1 to disinfect the interior of the centrifuge body 1. In order to maintain the continuous supply and uniform distribution of steam, new steam will enter the interior of the centrifuge body 1. With the continuous entry of steam, the pressure inside the centrifuge body 1 will gradually increase. Part of the steam will enter the second connecting pipe 301, and the increased air pressure will act on the sealing cover 304 to open the sealing cover 304. After the sealing cover 304 is opened, the steam will be discharged from the second connecting pipe 301, thereby reducing the pressure inside the centrifuge body 1. At the same time, with the opening of the sealing cover 304, the rotating rod 305 will also rotate. The rotating rod 305 is a component for connecting the sealing cover 304 and the fixed block 303, so as to maintain the balance and stability of the sealing cover 304. With the opening of the sealing cover 304, the torsion spring 306 will also be stretched, which can deform and store energy when subjected to an external force. In this process, the deformation and energy storage of the torsion spring 306 provide power for the closing of the sealing cover 304. When the internal pressure decreases and steam is no longer needed to be released, the torsion spring 306 will release the stored energy and push the sealing cover 304 to close the second connecting pipe 301 again.

[0036] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
