Description

Technical Field

[0001] This utility model relates to the field of centrifugal extraction technology, specifically a liquid sealing structure for a centrifugal extraction machine. Background Technology

[0002] Centrifugal extractors are widely used separation equipment in chemical, pharmaceutical, and food industries. Their core function is to effectively separate two or more immiscible solutions through centrifugal force generated by high-speed rotation. During centrifugal extraction, the sealing of the liquid is crucial, as it not only affects extraction efficiency but also directly impacts the stability and safety of the equipment.

[0003] Traditional liquid sealing structures in centrifugal extractors often employ static or simple dynamic sealing methods. These methods frequently suffer from incomplete sealing and leakage when faced with high pressure, high-speed rotation, and corrosive liquids. Leakage not only reduces extraction efficiency but can also lead to environmental pollution and safety hazards. Furthermore, some sealing structures require complex installation procedures and specialized tools, increasing operational difficulty and maintenance costs. Other sealing structures, while providing good sealing performance, are limited by material or design constraints and cannot withstand long-term high pressure and high-speed rotation, resulting in a short service life. Therefore, we propose a liquid sealing structure for centrifugal extractors. Utility Model Content

[0004] The purpose of this invention is to provide a liquid sealing structure for a centrifugal extractor 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 liquid sealing structure for a centrifugal extractor includes a centrifugal extractor, on which a plurality of mounting tubes are uniformly arranged, and a guide tube is provided on each mounting tube. A limit plate is also provided on the guide tube. A plurality of mounting blocks are uniformly arranged on the side wall of the limit plate. A through hole is provided through each mounting block. A slide rod is slidably arranged in the through hole. A slider is provided on the slide rod. A locking block is provided on the slider. A plurality of locking grooves are also uniformly arranged on the side wall of the mounting tube. The locking grooves are provided with insertion holes for cooperating with the locking blocks. A first spring is sleeved on the outside of the slide rod.

[0007] As a further embodiment of this utility model: the slot is further provided with a cavity, a telescopic rod is provided in the cavity, a slide plate is provided at the end of the telescopic arm of the telescopic rod, a limit rod is provided on the slide plate, and a limit is provided on the card block to cooperate with the limit rod.

[0008] As a further embodiment of this utility model: one end of the first spring is connected to the mounting block, and the other end of the first spring is connected to the slider.

[0009] As a further improvement of this utility model: a second spring is sleeved on the outside of the telescopic rod, one end of the second spring is connected to the slide plate, and the other end of the second spring is connected to the inner wall of the cavity.

[0010] As a further improvement of this utility model, the centrifugal extractor is provided with several feet evenly distributed at the bottom.

[0011] As a further improvement of this utility model: the upper mounting tube is a liquid inlet tube, and the lower mounting tube is a liquid outlet tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The combination of sliding rod, slider and locking block, as well as the corresponding slots and sockets, enables a quick and stable connection between the conduit and the installation tube. It is not only easy to operate without complicated installation steps and special tools, but also ensures that the conduit and the installation tube maintain good sealing performance under high pressure and high speed rotation working environment, effectively preventing liquid leakage and improving the extraction efficiency and safety of the centrifugal extractor.

[0014] 2. Under the action of the telescopic rod and the limiting rod, the sealing structure further enhances the connection stability between the conduit and the installation pipe. After the locking block is fully inserted into the slot, the telescopic rod pushes the sliding plate forward, causing the limiting rod to engage in the limiting groove on the locking block, forming a secondary lock. This not only improves the durability of the sealing structure and extends its service life, but also maintains the stability of the connection under extreme working conditions, such as severe vibration or impact, ensuring the stable operation of the centrifugal extractor.

[0020] Example

[0021] Please see Figures 1-3 In this embodiment of the present invention, a liquid sealing structure for a centrifugal extractor includes a centrifugal extractor 1. The bottom of the centrifugal extractor 1 is evenly provided with a plurality of support legs 2. Under the action of the support legs 2, the efficiency of the centrifugal extractor 1 is ensured, thereby ensuring its efficiency of use.

[0022] The centrifugal extractor 1 is evenly provided with several mounting pipes 3. The upper mounting pipe 3 is the liquid inlet pipe, and the lower mounting pipe 3 is the liquid outlet pipe. Under the action of the liquid inlet pipe and the liquid outlet pipe, the centrifugal extractor 1 can realize the automatic liquid loading and unloading function, thereby ensuring the efficiency of the centrifugal extractor 1.

[0023] The mounting tube 3 is equipped with a conduit 4. Under the action of the conduit 4, the centrifugal extractor 1 can better perform liquid centrifugal extraction. The conduit 4 is also equipped with a limiting plate 5. Several mounting blocks 6 are evenly arranged on the side wall of the limiting plate 5. A through hole is provided in the mounting block 6. A sliding rod 7 is slidably arranged in the through hole. A slider 8 is provided on the sliding rod 7. A locking block 9 is provided on the slider 8. Several slots 11 are evenly arranged on the side wall of the mounting tube 3. The slots 11 are provided with insertion holes that cooperate with the locking blocks 9. Under the action of the slots 11 and insertion holes, the connection quality between the mounting tube 3 and the conduit 4 is guaranteed, and the disassembly of the conduit 4 is also convenient. This facilitates subsequent operations such as replacing the conduit 4, ensuring the efficiency of the centrifugal extractor 1. A rubber gasket is also provided at the connection between the conduit 4 and the mounting pipe 3. The rubber gasket improves the sealing of the connection between the conduit 4 and the mounting pipe 3, reducing liquid leakage and ensuring the efficiency of the centrifugal extractor 1. A first spring 10 is sleeved on the outside of the slide rod 7. One end of the first spring 10 is connected to the mounting block 6, and the other end is connected to the slider 8. Under the action of the first spring 10, the connection quality between the locking block 9 and the locking groove 11 is improved, thus ensuring the installation quality of the conduit 4.

[0024] The slot 11 also has a cavity inside, in which a telescopic rod 12 is installed. A slide plate 13 is installed at the end of the telescopic arm of the telescopic rod 12. A limit rod 14 is installed on the slide plate 13. The block 9 is provided with a limit groove that works in conjunction with the limit rod 14. Under the action of the limit rod 14 and the limit groove, the connection quality between the block 9 and the slot 11 is improved, thereby ensuring the connection quality between the installation tube 3 and the guide tube 4. A second spring 15 is sleeved on the outside of the telescopic rod 12. One end of the second spring 15 is connected to the slide plate 13, and the other end of the second spring 15 is connected to the inner wall of the cavity. Under the action of the second spring 15, the connection quality between the limit rod 14 and the limit groove is ensured.

[0025] In actual use, the liquid to be extracted is first introduced into the centrifugal extractor 1 through the upper mounting tube 3. The mounting block 6 on the limiting plate 5 engages with the slot 11 on the side wall of the mounting tube 3 via the sliding rod 7 to achieve initial fixation. The slider 8 and the locking block 9 on the sliding rod 7 connect or separate the conduit 4 from the mounting tube 3. When the locking block 9 slides into the corresponding slot 11, the elastic force of the first spring 10 ensures that the locking block 9 is firmly held in the slot 11, thereby enhancing the stability of the connection. To further improve the sealing performance, a rubber gasket is also provided at the connection between the conduit 4 and the mounting tube 3 to effectively prevent... To prevent liquid leakage under high pressure or high-speed rotation, when the locking block 9 is fully inserted into the locking slot 11, the telescopic rod 12 pushes the sliding plate 13 forward, causing the limiting rod 14 on the sliding plate 13 to engage with the limiting groove on the locking block 9. This double locking mechanism remains stable under the elastic force of the second spring 15, ensuring that the conduit will not accidentally fall off even under strong centrifugal force. After the extraction process is completed, the conduit 4 can be easily disassembled by reversing the operation, facilitating cleaning, maintenance, or replacement. The entire design not only ensures the efficient operation of the centrifugal extractor but also greatly simplifies the daily maintenance and operation process.
