Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a concentration filtration centrifuge with an easily detachable filter screen. Background Technology

[0002] Centrifuges are machines that use centrifugal force to separate components in a mixture of liquids and solid particles or liquids and liquids. They mainly consist of a rotating drum, a filter screen, and a drive system, and are used in many fields such as chemical, pharmaceutical, and food industries.

[0003] In chemical separation, biological sample processing and other work scenarios, centrifuges are used in different ways. Due to the different properties of materials and different separation requirements, centrifuges need to be selected accordingly. Concentration and filtration centrifuges use the powerful centrifugal force generated by high-speed rotation, combined with special filter screens, to efficiently separate solid-liquid mixtures, realize material concentration and filtration, and greatly improve separation accuracy and efficiency.

[0004] However, existing concentration and filtration centrifuges have the following shortcomings:

[0005] In the existing technology, the drum and filter screen of a concentration filtration centrifuge are usually fixedly connected by a large number of bolt assemblies to ensure the stability of the filter screen when it is running at high speed. However, since the filter screen needs to be cleaned and replaced frequently during use, this filter screen installation method makes disassembly or installation particularly cumbersome, resulting in low maintenance efficiency, increased downtime, and impact on production progress.

[0006] Therefore, we propose a concentrator centrifuge with an easily removable filter screen to address the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a concentrator centrifuge with an easily detachable filter screen. By utilizing the quick-fixing action of the sliding component and the fixing component, the fixing component can be quickly moved out of the corresponding slot, thereby quickly releasing the fixed state of the filter component, thus solving the problems mentioned in the background art.

[0024] 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.

[0025] 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.

[0026] Example 1, as shown in the attached document Figure 1 -Appendix Figure 5 As shown, this utility model provides a technical solution: a centrifuge with an easily detachable filter screen, comprising a centrifuge body 1, a rotating drum 2 disposed on the inner wall of the centrifuge body 1, a fixing ring 3 fixedly connected to the inner wall of the rotating drum 2, a set of embedding blocks 4 fixedly connected to one side of the outer wall of the fixing ring 3, a first mounting ring 5 movably sleeved between the outer walls of the set of embedding blocks 4, a filter screen 6 fixedly connected to one side of the outer wall of the first mounting ring 5, a second mounting ring 7 fixedly connected to one side of the outer wall of the filter screen 6, a set of locking blocks 8 fixedly connected to one side of the outer wall of the second mounting ring 7, an annular limiting groove 9 formed on one side of the outer wall of each set of locking blocks 8, a circular sliding groove 10 formed on one side of the outer wall of the rotating drum 2, and a circular slider 11 slidably embedded in the inner wall of the circular sliding groove 10. A set of annular limiting blocks 12 are fixedly connected to the outer wall of the circular slider 11, and the outer wall of the set of annular limiting blocks 12 is movably inserted into the interior of a set of annular limiting grooves 9. A rotating block 13 is fixedly connected to one side of the outer wall of the circular slider 11. A return spring 14 is fixedly connected to the inner wall of the rotating block 13. A fixing block 15 is fixedly connected to the outer wall of the return spring 14, and the fixing block 15 is movably inserted into the interior of the rotating block 13. A positioning block 16 is fixedly connected to one side of the outer wall of the drum 2. A fixing groove 17 is opened on one side of the outer wall of the positioning block 16, and the outer wall of the fixing block 15 is movably inserted into the interior of the fixing groove 17. A set of slots 18 is opened on the outer wall of the drum 2, and the outer wall of a set of locking blocks 8 is movably inserted into the interior of the set of slots 18.

[0027] The effect achieved by the entire embodiment 1 is as follows: When it is necessary to disassemble the filter screen 6 for maintenance or replacement, first move the fixing block 15 downward to disengage it from the fixing groove 17, thereby releasing the fixing of the rotating block 13. Then rotate the rotating block 13, which drives the circular slider 11 to move within the circular groove 10. The circular slider 11 further drives a set of annular limiting blocks 12 to move out of the corresponding annular limiting groove 9, thereby releasing the fixing of the second mounting ring 7. Subsequently, move the second mounting ring 7 to separate the first mounting ring 5 from a set of embedded blocks 4. At this time, the filter screen 6 can be quickly removed from the centrifuge body 1. This disassembly and assembly method can quickly disassemble the filter screen 6, greatly improving the convenience of filter screen disassembly, improving maintenance efficiency, reducing downtime, and ensuring production progress.

[0028] Example 2, as Figure 2-5 As shown, a conveying pipe 19 is fixedly connected to the outer wall of the centrifuge body 1, a spray pipe 20 is fixedly connected to the output end of the conveying pipe 19, a set of spray nozzles 21 is fixedly connected to the outer wall of the spray pipe 20, a water pump 22 is fixedly connected to the input end of the conveying pipe 19, a connecting pipe 23 is fixedly connected to the input end of the water pump 22, and a water tank 24 is fixedly connected to the input end of the connecting pipe 23.

[0029] The effect achieved by the entire embodiment 2 is as follows: when the filter screen 6 needs to be cleaned after long-term use, the water pump 22 is started first. After the water pump 22 is started, it draws clean water from the water tank 24 and pressurizes it, so that it flows through the delivery pipe 19 to the spray pipe 20. Then, under the atomization effect of a set of spray nozzles 21, the filter screen 6 is thoroughly rinsed in the form of uniform water mist, thereby effectively removing the impurities and residues attached to the filter screen 6, so that the filter screen 6 can restore its good filtration performance.

[0030] The working principle of the entire device is as follows: When the filter screen 6 needs to be disassembled for maintenance or replacement, first open the centrifuge sealing cover, then move the fixing block 15 downwards to disengage it from the inside of the fixing groove 17, thereby releasing the fixing of the rotating block 13. During this process, the return spring 14 is compressed. Then rotate the rotating block 13, which drives the circular slider 11 to move within the circular groove 10. The circular slider 11 then drives a set of annular limiting blocks 12 to move out of the corresponding annular limiting groove 9, releasing the fixing of a set of locking blocks 8 and the second mounting ring 7. Then move the second mounting ring 7 outwards to disengage the set of locking blocks 8 from the corresponding locking groove 18. At the same time, the second mounting ring 7 drives the first mounting ring 5 to separate from a set of embedded blocks 4, thereby removing the filter screen 6 from the inside of the centrifuge body 1. Quickly remove the filter screen 6. Conversely, when the filter screen 6 needs to be installed, simply reverse the above steps and use the elastic reset of the return spring 14 to make the fixing block 15 snap into the corresponding limit groove, keeping the circular slider 11 fixed. At this time, the filter screen assembly and the rotating drum 2 form a solid tenon and tenon connection, ensuring that the filter screen 6 can also be stably fixed under the action of centrifugal force. When the filter screen 6 needs to be cleaned after long-term use, first start the water pump 22. The water pump 22 draws clean water from the water tank 24 and pressurizes it. The clean water flows through the delivery pipe 19 to the spray pipe 20. Then, under the atomization effect of a set of spray nozzles 21, the filter screen 6 is rinsed in the form of uniform water mist. At the same time, the rotating drum 2 is driven to rotate by the internal drive component of the centrifuge body 1. The rotating drum 2 drives the filter screen 6 to rotate, thereby performing a comprehensive cleaning and maintenance operation on the filter screen 6.

[0031] 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.
