[0001] This utility model relates to the field of centrifuge technology, and in particular to a bag-shaking centrifuge equipped with adaptive adjustment of bag-shaking force. Background Technology

[0002] Centrifuges are devices that work on the principle of centrifugal force. Their drive unit drives the drum to rotate at high speed to generate centrifugal force, which separates mixtures of materials with different densities. They are widely used in solid-liquid or liquid-liquid separation in industries such as chemical, pharmaceutical and food processing.

[0003] In chemical production or laboratory separation experiments, filter bags are used inside centrifuges to retain solid particles and filter liquids in order to achieve efficient solid-liquid separation. Shaking bag centrifuges utilize the high-frequency vibration of filter bags under the action of a shaking device to break the adsorption force between solid materials and filter bags, causing solid materials to fall off the filter bags, thereby achieving the purpose of unloading and improving the efficiency of separation operations.

[0004] However, existing bag-shaking centrifuges have the following shortcomings:

[0005] In existing technologies, bag shaking centrifuges typically use filter bag shaking to remove solid materials. However, the shaking force of existing bag shaking centrifuges is usually fixed and cannot be adjusted in real time according to material characteristics (such as viscosity, particle size, etc.) and stacking conditions. This results in incomplete unloading or excessive shaking that damages the filter bags, affecting production efficiency and equipment lifespan.

[0006] Therefore, we propose a bag-shaking centrifuge equipped with adaptive adjustment of bag-shaking force to solve the problems mentioned above. Utility Model Content

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, as shown in the attached document Figure 1 - Appendix Figure 5 As shown, this utility model provides a technical solution: a bag-shaking centrifuge equipped with adaptive adjustment of bag-shaking force, including a shock-absorbing mechanism 1, and a bag-shaking mechanism 2 is provided on the top of the shock-absorbing mechanism 1;

[0028] The bag-shaking mechanism 2 includes a centrifuge body 201. A rotating drum 202 is provided on the inner wall of the centrifuge body 201. A set of return springs 203 are fixedly connected to the bottom of the inner wall of the rotating drum 202. An annular plate 204 is fixedly connected between the tops of the set of return springs 203. A fixing plate 205 is fixedly connected to the top of the annular plate 204. A filter bag 206 is fixedly connected to the outer wall of the fixing plate 205. A connecting frame 207 is fixedly connected to the inner wall of the centrifuge body 201. A first bearing 208 is fixedly inserted into the inner wall of the connecting frame 207. A rotating shaft 209 is fixedly inserted into the inside of the first bearing 208. A drive motor 210 is fixedly connected to one side of the outer wall of the rotating shaft 209. A rotating disk 211 is fixedly sleeved on the outer wall of the rotating shaft 209. A mounting plate 212 is fixedly connected to one side of the outer wall of the rotating disk 211. A groove 21 is formed on one side of the outer wall of the mounting plate 212. 3. A slider 214 is slidably embedded in the inner wall of the slide groove 213. A second bearing 215 is fixedly inserted into the inner wall of the slider 214. An adjusting screw 216 is fixedly inserted into the inside of the second bearing 215. The inner wall of the mounting plate 212 is threadedly connected to the outer wall of the adjusting screw 216. A first linkage rod 217 is fixedly connected to one side of the outer wall of the slider 214. A connecting rod 218 is movably sleeved on the outer wall of the first linkage rod 217. A second linkage rod 219 is movably inserted into the inner wall of the connecting rod 218. A moving column 220 is movably sleeved on the outer wall of the second linkage rod 219. A guide block 221 is movably sleeved on the outer wall of the moving column 220. One side of the outer wall of the connecting frame 207 is fixedly connected to one side of the outer wall of the guide block 221. A crossbar 222 is fixedly connected to the bottom of the moving column 220. Two rubber pressure blocks 222 are fixedly connected to the bottom of the crossbar 222.

[0029] The overall effect achieved in Embodiment 1 is as follows: When the filter bag 206 needs to be shaken to achieve unloading, the drive motor 210 is first started, and its output end drives the rotating shaft 209 and the rotating disk 211 to rotate. The rotating disk 211 causes the connecting rod 218 to reciprocate through the first linkage rod 217. The connecting rod 218 drives the moving column 220 and the crossbar 222 to reciprocate together. The guide block 221 ensures the stability and accuracy of the movement of the moving column 220. At this time, the crossbar 222 drives the two rubber pressure blocks 223 to reciprocate and press the fixed plate 205. Under the elastic action of the four return springs 203, the fixed plate 205... 05. The filter bag is continuously shaken, causing the material to fall off the filter bag and completing the unloading. In addition, by rotating the adjusting screw 216, the slider 214 can be moved in the slide groove 213 through the threaded transmission mechanism, thereby changing the position of the first linkage rod 217. This changes the stroke of the reciprocating motion of the connecting rod 218 and the moving column 220, thereby adjusting the downward pressure of the rubber pressure block 223 on the fixed plate 205. In this way, the shaking force of the bag shaking centrifuge can be adjusted, allowing the shaking force to be adjusted in real time according to the material characteristics. This method can ensure thorough unloading and avoid excessive shaking that could damage the filter bag, thereby extending the service life of the equipment.

[0030] Example 2, as Figure 2-5 As shown, the shock absorption mechanism 1 includes a support frame 101. Four lower shock-absorbing rubber pads 102 are fixedly connected to the top of the support frame 101. A damper 103 is fixedly connected to the top of each of the four lower shock-absorbing rubber pads 102. A shock-absorbing spring 104 is movably sleeved on the outer wall of each of the four dampers 103. An upper shock-absorbing rubber pad 105 is fixedly connected to the top of each of the four dampers 103. The top of the four upper shock-absorbing rubber pads 105 is fixedly connected to the bottom of the centrifuge body 201.

[0031] The overall effect of Embodiment 2 is as follows: During use, the centrifuge will generate a large amount of vibration. At this time, the four dampers 103 will first play their role, absorbing and dissipating vibration energy through the internal damping medium, suppressing the rapid transmission and amplification of vibration. At the same time, the four shock-absorbing springs 104 can further buffer and disperse the vibration impact force, using their elastic deformation to store and release energy, reducing the impact of vibration on the overall structure of the centrifuge. Furthermore, the four lower shock-absorbing rubber pads 102 and the four upper shock-absorbing rubber pads 105 can increase the flexibility and friction of the contact surface, on the one hand is to isolate the transmission of vibration to the ground or installation platform, and on the other hand, to prevent the centrifuge from shifting and shaking during vibration, ensuring that the vibration is effectively controlled and attenuated, thereby ensuring the stability and reliability of the centrifuge operation, and reducing the noise generated by vibration and the risk of damage to equipment parts.

[0032] The working principle of the entire device is as follows: When the filter bag 206 needs to be shaken to achieve unloading, the drive motor 210 is started first. Its output end drives the rotating shaft 209 to rotate, and the rotating shaft 209 in turn drives the rotating disk 211 to rotate. Since the eccentric end of the rotating disk 211 is provided with the first linkage rod 217, the rotating disk 211 drives the connecting rod 218 to reciprocate through the first linkage rod 217. The connecting rod 218 then drives the moving column 220 and the crossbar 222 to reciprocate together. At this time, the crossbar 222 drives the two rubber pressure blocks 223 to press the fixed plate 205 back and forth. Under the elastic action of the four return springs 203, the fixed plate 205 and the filter bag shake continuously, thereby causing the material to fall off the filter bag and completing the unloading process. In addition, by rotating the adjusting screw 216, the slider 214 can move inside the slide groove 213, thereby changing the first linkage rod 217. At position 7, the reciprocating stroke of the connecting rod 218 and the moving column 220 changes, causing the downward pressure of the rubber block 223 on the fixed plate 205 to change accordingly. This allows for adjustment of the shaking force of the bag-shaking centrifuge, ensuring that the shaking force can be adjusted in real time according to the material characteristics. During centrifuge operation, a large amount of vibration is generated. At this time, the four dampers 103 first play their role, quickly absorbing and dissipating vibration energy and suppressing the propagation of vibration. At the same time, the four shock-absorbing springs 104 can further buffer and disperse the vibration impact force, reducing the impact of vibration on the centrifuge structure. Furthermore, the four lower shock-absorbing rubber pads 102 and the four upper shock-absorbing rubber pads 105 can increase the flexibility and friction of the contact surface, isolating the vibration from being transmitted to the support frame 101, ensuring that the vibration is effectively controlled and attenuated, thereby ensuring the stability and reliability of the centrifuge operation.

[0033] 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.
