Description

Technical Field

[0001] This invention relates to the field of parasite detection, specifically a filter device for detecting parasites in meat products. Background Technology

[0002] Food safety is a crucial component of the social health protection system, and parasitic contamination in food has always been a key aspect of food quality testing. Especially in meat products, certain parasites or their eggs may remain in the meat during processing, leading to parasitic infections after consumption and posing a threat to consumers' health.

[0003] Therefore, in the food testing industry, parasite testing of meat products to promptly detect and remove potential parasite contamination is a crucial step in ensuring food safety. Conventional parasite detection methods typically require pretreatment, filtration, and sedimentation separation of meat samples, followed by analysis using microscopy or molecular biology techniques to determine the presence of parasites or parasite eggs in the sample.

[0004] In parasite detection, the filtration and sedimentation device is a core component, primarily used to separate parasites or their eggs from impurities such as meat tissue and fat. Through a well-designed filtration and sedimentation mechanism, most impurities can be effectively removed, making the target analyte easier to observe and detect. Generally, the filtration and sedimentation device needs to have high filtration precision to ensure the sensitivity and accuracy of parasite detection.

[0005] However, meat samples, after being pulverized, contain higher levels of fat and viscous protein. These substances easily adhere to the filter screen during filtration, clogging the pores and significantly reducing filtration efficiency. Furthermore, traditional sedimentation equipment typically relies on gravity settling, which is slow and cannot quickly separate the target analytes, leading to prolonged testing time and impacting efficiency. In some cases, operators even need to manually clean the filter screen to maintain the filtration process, further increasing the complexity of the testing work. Summary of the Invention

[0020] This invention provides a filter device for detecting parasites in meat products. It has the following beneficial effects:

[0021] 1. This invention utilizes a squeezing mechanism to move the connecting block and sealing plate inside the separation tank. At this time, the sealing plate and connecting block can move simultaneously towards the bottom of the separation tube. The connecting block can squeeze the sample at the top of the separation tube, allowing it to quickly pass through multiple filters and enter the bottom of the separation tube, thereby accelerating the sample filtration speed.

[0022] 2. This invention uses a second drive motor to rotate the paddle, causing the sample at the top of the separation tube to rotate as well. At this time, the liquid and solid particles in the sample move in a spiral motion, generating centrifugal force during rotation. Due to this centrifugal force, denser precipitates can more quickly gather towards the bottom of the separation tube, thereby accelerating the sedimentation process and improving the accuracy and efficiency of the separation.

[0023] 3. In this invention, the drive motor three drives the active wheel to rotate, which in turn drives the driven wheel one via belt one, causing the rotating shaft one and the eccentric wheel one to rotate. Subsequently, another driven wheel one drives the driven wheel two via belt two, causing the rotating shaft two and the eccentric wheel two to rotate. Since the eccentric wheel one and the eccentric wheel two are located on opposite sides of the support plate, under their action, the support plate can be driven to reciprocate along the sliding groove inside the base. This reciprocating motion transmits vibrational force, further causing the separation tube and the sample inside to vibrate. During the vibration process, the particles in the sample can be separated more effectively under the dual action of centrifugal force and vibrational force, promoting the aggregation and stratification of sediments, thereby improving the efficiency and accuracy of separation.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] To better understand the present invention, the above content will be described in detail below with reference to specific embodiments.

[0038] Example 1: Please refer to the appendix Figures 1-11 This invention provides a filtration device for detecting parasites in meat products, comprising: a base 1, a separation tube 2 mounted on the top surface of the base 1, a filtration mechanism 6 disposed inside the separation tube 2 for filtering samples; a support rod 3 mounted on one side of the top surface of the base 1, a squeezing mechanism 4 disposed inside the support rod 3 for driving a connecting block 404 and a sealing plate 410 to move inside the separation tube 2; and a stirring mechanism 5 connected to the squeezing mechanism 4 for moving with the connecting block 404 and stirring the sample inside the separation tube 2.

[0039] In this embodiment, the liquid sample can be held in the separation tube 2. After the liquid sample enters the separation tube 2, it is filtered by the filtration mechanism 6. At the same time, the squeezing mechanism 4 can drive the connecting block 404 and the sealing plate 410 to move within the separation tube 2. At this time, the connecting block 404 can squeeze the liquid sample at the top of the separation tube 2, thereby accelerating the speed at which the liquid sample passes through the filtration mechanism 6 and improving the filtration rate.

[0040] Please see the appendix Figures 1-5 The extrusion mechanism 4 includes a motor 400, which is a double-headed motor. Both output ends of the motor 400 are fixedly connected to threaded rods 401. One threaded rod 401 is rotatably connected to the inner top of the support rod 3, and its outer wall is threadedly connected to a slider 402. The slider 402 is slidably connected to the inner top of the support rod 3. A crossbeam 403 is fixedly connected to one side of the slider 402, and one side of the crossbeam 403 is fixedly connected to a connecting block 404. A sealing ring 405 is fixedly connected to the outer wall of the connecting block 404, and the sealing ring 405 is located on the inner wall of the separation tube 2. The other threaded rod... 401 is rotatably connected to one side of the base 1, and a connecting rod 406 is threaded to its outer wall. A retainer 407 is fixedly connected to one side of the connecting rod 406. A retainer plate 408 is slidably connected inside the retainer 407. A pull rod 409 is fixedly connected to the middle of the retainer plate 408. The middle of the pull rod 409 is slidably connected to the base 1, and the top of the pull rod 409 is fixedly connected to the sealing plate 410. The outer wall of the sealing plate 410 is slidably connected to the bottom of the inner wall of the separation tube 2. A guide rod 411 is slidably connected to the other side of the connecting rod 406. The guide rod 411 is fixedly connected to the inside of the base 1. The stirring mechanism 5 includes a second motor 501. The second motor 501 is fixedly connected to one side of the top surface of the crossbeam 403. A blade 502 is fixedly connected to the output end of the second motor 501, and the output end of the second motor 501 passes through the connecting block 404. The blade 502 is located below the connecting block 404.

[0041] In this embodiment, a drive motor 400 simultaneously drives two threaded rods 401 to rotate. The threaded rod 401 at the top of the drive motor 400 can drive the slider 402, the crossbar 403, and the connecting block 404 to move, thereby allowing the connecting block 404 to enter the top of the separation tube 2. A sealing ring 405 is also provided on the outside of the connecting block 404, thus preventing the liquid sample from being squeezed out of the separation tube 2. The connecting block 404 also drives the paddle 502 to enter the top of the separation tube 2, at which point the drive motor 501 can drive the paddle 502 to rotate. This can cause the liquid sample to move in a spiral path, thereby generating centrifugal force, which can slow down the accumulation of precipitates in the liquid sample. Due to the centrifugal force, the denser precipitates can gather to the bottom of the separation tube 2 more quickly, thereby accelerating the sedimentation process and improving the accuracy and efficiency of separation. The threaded rod 401 at the bottom of the motor 2 501 can drive the connecting rod 406, the card seat 407, the pull rod 409 and the sealing plate 410 to move. At this time, the sealing plate 410 will be at the bottom of the separation tube 2, thus reserving space for the liquid sample to enter the bottom of the separation tube 2.

[0042] Please see the appendix Figures 9-10The filtration mechanism 6 includes a support ring 601 and a filter screen 602. The support ring 601 is fixedly connected to the inner wall of the separation tube 2. The filter screen 602 is located in the middle of the support ring 601. Several support rings 601 and filter screens 602 are provided. The diameter and pore size of the filter screens 602 decrease from top to bottom. The support rings 601 are all annular. The diameter of the inner wall of the support rings 601 decreases from top to bottom. The bottom of the outer wall of the separation tube 2 is threadedly connected to a discharge pipe 603. A sealing cap is installed on one side of the discharge pipe 603. The discharge pipe 603 is located below the bottom surface of the bottom filter screen 602.

[0043] In this embodiment, by setting multiple filter screens 602 inside the separation tube 2, the liquid sample can be filtered in stages. The pore size of the multiple filter screens 602 decreases sequentially from top to bottom, thus enabling staged filtration of the liquid sample. Because the pore size of the multiple filter screens 602 decreases sequentially from top to bottom, larger particles of impurities can be intercepted by the upper filter screen 602, while smaller particles continue to flow downwards and are further filtered in the finer lower filter screen 602. This design effectively improves filtration accuracy, prevents larger particles from clogging the bottom filter screen 602, and ensures more thorough separation of tiny precipitates, thereby improving the overall separation effect. Furthermore, this structure reduces the risk of clogging of the filter 602, improves the service life of the equipment, and maintains the stability of filtration efficiency. The bottom of the separation tube 2 is also connected to the discharge tube 603. Therefore, after the liquid sample is filtered, by letting it stand, the liquid sample can be separated into supernatant and precipitate. At this time, the sealing cap can be removed, and then the motor 501 can be used to drive the sealing cap close to the middle of the separation tube 2. At this time, the liquid level of the supernatant will gradually rise. When the supernatant enters the discharge tube 603, it can be discharged from the discharge tube 603. After the supernatant is discharged, a tool can be inserted into the separation tube 2 along the discharge tube 603, and then the precipitate can be removed from the inside of the separation tube 2.

[0044] Please see the appendix Figure 1 , Figure 3 and Figure 8 The base 1 has a mounting mechanism 8 on its top surface. The mounting mechanism 8 includes a support plate 801, a diagonal rod 802 fixedly connected to the top surface of the support plate 801, a bracket 803 fixedly connected to the top of the diagonal rod 802, a retaining ring 804 fixedly connected to the middle of the outer wall of the separation tube 2, the retaining ring 804 being located in the middle of the bracket 803, and a pressure ring 805 threadedly connected to the outer wall of the bracket 803. The bottom of the separation tube 2 contacts the middle of the top surface of the support plate 801. A through hole 807 is formed in the middle of the top surface of the support plate 801, and a pull rod 409 is disposed within the through hole 807. A groove 806 is formed on the outer side of the middle of the top surface of the support plate 801, and the bottom of the separation tube 2 is located within the groove 806. A movable groove 102 is provided at the inner bottom of the base 1, and the connecting rod 406 and the retaining seat 407 are slidably connected within the movable groove 102.

[0045] In this embodiment, the separation tube 2 can be supported by the support plate 801, the diagonal bar 802 and the bracket 803, and the retaining ring 805 can be rotated to press the retaining ring 804 on the outer wall of the separation tube 2 between the bracket 803 and the retaining ring 805, thereby improving the stability of the separation tube 2 during use.

[0046] Please see the appendix Figure 3 , Figure 6 , Figure 7 and Figure 11 A vibration mechanism 7 is installed inside the base 1. The vibration mechanism 7 includes a motor 701, a rotating shaft 702, and a rotating shaft 703. The motor 701 is fixedly connected to one side of the middle of the base 1. The rotating shafts 702 and 703 are rotatably connected to both sides inside the base 1, and are located on both sides of the support plate 801. Eccentric wheels 704 and 705 are fixedly connected to the top of the rotating shafts 702 and 703, respectively. The output end of 701 is fixedly connected to a drive wheel 706. The bottom of the first rotating shaft 702 is fixedly connected to two driven wheels 707. The bottom of the second rotating shaft 703 is fixedly connected to a driven wheel 708. The drive wheel 706 is connected to one driven wheel 707 via a belt 709. The other driven wheel 707 is connected to the driven wheel 708 via a belt 710. The long axis side of the eccentric wheel 704 and the short axis side of the eccentric wheel 705 are in contact with the two sides of the outer wall of the support plate 801, respectively. Two shafts, 703 and 702, are provided, with each shaft positioned on either side of the support plate 801. Two drive wheels 706 are mounted on the output end of the motor 701, and each drive wheel 706 is connected to a driven wheel 707 via two belts 709. Each driven wheel 707 is connected to a driven wheel 708 via two belts 710. A groove 101 is provided at the top of the inner sidewall of the base 1, and the support plate 801 is slidably connected inside the groove 101.

[0047] In this embodiment, after the liquid sample enters the bottom of the separation tube 2, impurities in the liquid sample accumulate on the filter screen 602, thus obtaining a suspension of the liquid sample. The drive motor 701 then rotates the drive wheel 706, which in turn drives the belt 709 to rotate the driven wheel 707, the shaft 702, and the eccentric wheel 704. The belt 710 transmits power from the driven wheel 707 to the driven wheel 708, which in turn drives the shaft 703 and the eccentric wheel 704. 5 rotates, and since eccentric wheel 704 and eccentric wheel 705 are distributed on both sides of the support plate 801, the support plate 801 can be driven to swing back and forth along the sliding groove 101 inside the base 1. At this time, the separation tube 2 can be driven to move back and forth, and finally the vibration is transmitted to the separation tube 2, which can further drive the separation tube 2 and the liquid sample inside it to vibrate. At the same time, during the vibration process, the particles in the sample can be separated more effectively under the dual action of centrifugal force and vibration force, promoting the aggregation and stratification of sediments, thereby improving the efficiency and accuracy of separation.

[0048] Working principle: When in use, first pour the liquid sample into the separation tube 2 from the top. The sample will then accumulate at the top of the separation tube 2 and slowly pass through the multi-stage filter 602. The pore size of the multiple samples decreases from top to bottom, so the liquid sample can be filtered in multiple stages.

[0049] Furthermore, during filtration, the drive motor 400 can simultaneously rotate two threaded rods 401. When the threaded rod 401 at the top of the drive motor 400 rotates, it causes the slider 402 to slide inside the support rod 3, thereby causing the crossbar 403 to approach the separation tube 2. This causes the connecting block 404 and the sealing ring 405 to enter the top of the separation tube 2. Subsequently, the drive motor 501 can rotate the paddle 502, which causes the liquid sample at the top of the separation tube 2 to move in a spiral motion, thereby generating centrifugal force. Using the centrifugal force, denser precipitates can more quickly gather towards the bottom of the separation tube 2, thus accelerating the sedimentation process and improving separation. The precision and efficiency are improved. When the threaded rod 401 at the bottom of the motor 400 rotates, it will drive the connecting rod 406 to move down away from the separation tube 2. At this time, the connecting rod 406 will drive the card seat 407, card plate 408 and pull rod 409 to move, thereby driving the sealing plate 410 away from the bottom filter screen 602 in the separation tube 2. This provides space for the liquid sample to stay when it enters the bottom of the separation tube 2. After the connecting block 404 drives the sealing ring 405 into the separation tube 2, the connecting block 404 and the sealing ring 405 will squeeze the liquid sample at the bottom of the separation tube 2. By pressurizing the liquid, the speed of the liquid passing through the filter screen 602 can be accelerated, thus increasing the filtration rate.

[0050] After filtration is complete, the second motor is turned off, and the first motor is driven to reverse. This allows the connecting block 404 to be removed from the inside of the separation tube 2, and the sealing plate 410 will approach the bottom filter screen 602. Then, the third motor 701 is driven, which in turn drives the drive wheel 706 to rotate. The drive wheel 706, via belt 709, drives a driven wheel 707, which in turn rotates the shaft 702 and the eccentric wheel 704. The other driven wheel 707, via belt 71... The driven wheel 708 drives the rotating shaft 703 and the eccentric wheel 705 to rotate. Since the eccentric wheel 704 and the eccentric wheel are in contact with both sides of the support plate 801, their rotation causes the support plate 801 to reciprocate along the groove 101 inside the base 1. This movement, in turn, causes the separation tube 2 to vibrate. The vibration is transmitted to the separation tube 2, further vibrating the separation tube 2 and the liquid sample inside it. During vibration, the particles in the sample are more effectively separated under the combined action of centrifugal force and vibration, promoting the aggregation and stratification of sediments, thereby improving separation efficiency and accuracy.

[0051] Then, allow the liquid sample to stand to allow the precipitate inside to settle. After sedimentation, first open the sealing cap, then drive motor 400 to continue moving the sealing plate 410 closer to the bottom filter screen 602. At this time, the sealing plate 410 can cause the liquid level of the supernatant to gradually rise, and then be discharged from the discharge pipe 603. After the supernatant is discharged, the tool can be inserted into the separation tube 2 along the discharge pipe 603 to remove the precipitate. Then, the precipitate can be tested for parasites.

[0052] Example 2: Based on Example 1, in this example, the crossbeam 403 can be divided into two sections, and the two sections of the crossbeam 403 can be connected by screws and nuts. Therefore, after the sediment is removed, the crossbeam 403 can be disassembled, and then the connecting block 404 and the blade 502 can be moved out of the top of the separation tube 2. At this time, the pressure ring 805 can be rotated to remove it from the outside of the separation tube 2. Then the separation tube 2 can be pulled out to separate it from the sealing plate 410. At this time, the sediment will remain on the top surface of the separation plate, so the obtained sediment can also be removed in this way.

[0053] After separating the separation tube 2 from the sealing plate 410, the separation tube 2 can be inverted. Since the diameter and pore size of the filter screen 602 decrease from top to bottom, and the support rings 601 are all annular, and the diameter of the inner wall of the support ring 601 decreases from top to bottom, by inverting the separation tube 2, the filter screen 602 with the largest diameter is at the bottom, while the filter screen 602 with the smallest diameter is at the top. At the same time, the support ring 601 with the largest inner wall diameter will be at the bottom, while the support ring 601 with the smallest inner wall diameter will be at the top. Therefore, the filter screen 602 can be removed from the separation tube 2 for cleaning, thereby improving the convenience of cleaning.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
