However, when using a centrifuge for solid-liquid separation, the centrifuge drum is subjected to impacts from the solid-liquid mixture, which can cause wear and tear on the drum. Frequent maintenance is required, which increases the maintenance cost of the centrifuge. Therefore, the maintenance cost of solid-liquid separation equipment is relatively high.

[0011] In some or more embodiments, the inner peripheral wall of the spiral ring abuts against the outer peripheral wall of the connector, and the outer peripheral wall of the spiral ring abuts against the spacer.

[0012] In some or more embodiments, the rotating member further includes:

[0013] The shaft portion is rotatably inserted into the support member and extends into the solid cavity;

[0014] The docking part is connected to the shaft part and located inside the solid cavity. The groove and the separation outlet are both located in the docking part. The spiral ring part is connected to the docking part and located in the groove.

[0015] In some or more embodiments, the support member has a solid outlet communicating with the solid cavity, and the rotating member further includes:

[0016] The fan blade portion is connected to the docking portion and protrudes from the docking portion, and the fan blade portion is located in the solid cavity.

[0017] In some or more embodiments, the support member is provided with an outlet communicating with the liquid chamber.

[0018] In some or more embodiments, the solid-liquid separation device further includes:

[0019] The mounting component has a chamber and an inlet and an outlet communicating with the chamber. The inlet allows the solid-liquid mixture to flow in, and the outlet communicates with the inner hole of the connector.

[0020] A screw, rotatably inserted into the mounting and inserted into the chamber, is configured to rotate relative to the mounting to expel the solid-liquid mixture to the outlet.

[0021] In some or more embodiments, the mounting component includes:

[0022] The mounting body has a cylindrical hole and an inlet. The inlet is connected to one end of the cylindrical hole, and the outlet is connected to the other end of the cylindrical hole. The screw is rotatably inserted into the mounting body and is threaded into the wall of the cylindrical hole.

[0023] The connecting part is provided with a discharge groove and the outlet. The discharge groove is connected to the other end of the cylindrical hole and forms the chamber with the cylindrical hole. The inner hole of the connecting member is connected to the outlet.

[0024] In some or more embodiments, the solid-liquid separation device further includes:

[0025] The filter element is provided with a filter tank and an outlet. The opening of the filter tank is for the solid-liquid mixture to flow in, and the outlet is connected to the filter tank and the outlet is connected to the inlet.

[0026] A filter screen is connected to the filter element and is located between the opening of the filter tank and the outlet.

[0027] In some or more embodiments, the solid-liquid separation device further includes:

[0028] A vibration motor is connected to the filter element and spaced apart from the filter tank.

[0029] The beneficial effects provided by one or more embodiments of this application are as follows:

[0030] When a solid-liquid mixture needs to be separated, the mixture can enter through the inner hole of the connector. The connector has a radially penetrating extrusion hole, through which the solid-liquid mixture enters. A spacer is fitted onto the closed end of the connector, forming an annular groove between the spacer and the connector that connects to the extrusion hole. The solid-liquid mixture flowing from the extrusion hole to the outer peripheral wall of the connector enters the annular groove, and the rotating component abuts against the spacer. The groove of the rotating component aligns with the opening of the annular groove, forming a separation chamber. The separation outlet on the rotating component connects to the groove, thus also connecting to the separation chamber. The spiral ring of the rotating component is located in the separation chamber and is rotatably fitted onto the connector. When the rotating component rotates relative to the connector, the spiral ring rotates relative to the connector, squeezing the solid-liquid mixture flowing from the extrusion hole and adhering to the outer peripheral wall of the connector, separating the liquid from the mixture. The liquid flows out through the drain hole of the spacer, while the solid separated by the spiral ring enters the separation outlet. During solid-liquid separation, the rotating component also carries rotational inertia as it exits the separation outlet. The support component rotates in conjunction with the rotating component and is fitted with the connecting component. The liquid chamber of the support component collects the liquid flowing from the drain hole, while the solid chamber accommodates part of the rotating component. The rotating component inserts into the through hole and abuts against the isolator, providing support and some isolation between the liquid and solid chambers. The solid chamber connects to the separation outlet and collects the solid flowing from it, thus completing the separation of the solid and liquid components in the solid-liquid mixture. The solid-liquid mixture is separated by the spiral ring compression, resulting in high and stable separation efficiency. The solid-liquid mixture does not impact the connecting component, preventing damage and reducing the need for frequent maintenance. This reduces maintenance costs and, to some extent, addresses the high maintenance costs associated with solid-liquid separation equipment. Attached Figure Description

[0040] The present application will now be described in conjunction with the accompanying drawings:

[0041] Figure 1 This application shows a schematic diagram of the structure of a solid-liquid separation device according to some embodiments or certain embodiments. (Refer to...) Figure 1 This application provides a solid-liquid separation device for separating solid-liquid mixtures, comprising:

[0042] The connector 1 is barrel-shaped and has an inner hole 11 for the solid-liquid mixture to enter. The connector 1 has a radially extending extrusion hole 12 that communicates with the inner hole 11.

[0043] The isolator 2 is sleeved onto one closed end of the connector 1, and forms an annular groove 5 with the connector 1 to communicate with the extrusion hole 12. The isolator 2 is provided with a drain hole 21 communicating with the annular groove 5.

[0044] The rotating member 3 is provided with a spiral ring 31, a groove 32 and a separation outlet 33 that connects to the groove 32. The spiral ring 31 is located in the groove 32. The rotating member 3 abuts against the isolation member 2. The groove 32 and the annular groove 5 form a separation cavity. The spiral ring 31 is rotatably sleeved on the connecting member 1. The rotating member 3 is configured to rotate relative to the connecting member 1 so that the spiral ring 31 squeezes the solid in the solid-liquid mixture into the separation outlet 33.

[0045] Support member 4 is sleeved on connecting member 1 and rotatably sleeved on rotating member 3. Support member 4 has a liquid cavity 41, a solid cavity 42 and a through hole 43. Through hole 43 connects solid cavity 42 and liquid cavity 41. Liquid cavity 41 accommodates isolation member 2 and is connected to drain hole 21. Solid cavity 42 accommodates part of rotating member 3. Rotating member 3 is inserted into through hole 43 and abuts against isolation member 2. Solid cavity 42 is connected to separation outlet 33.

[0046] When it is necessary to separate a solid-liquid mixture, the solid-liquid mixture can enter through the inner hole 11 of the connector 1. The connector 1 has a radially extending extrusion hole 12 that penetrates itself. The solid-liquid mixture can enter the extrusion hole 12 that connects to the inner hole 11 of the connector 1. A spacer 2 is sleeved on the closed end of the connector 1. An annular groove 5 that connects to the extrusion hole 12 is formed between the spacer 2 and the connector 1. The solid-liquid mixture flowing from the extrusion hole 12 to the outer peripheral wall of the connector 1 will enter the annular groove 5. The rotating member 3 abuts against the spacer 2. The groove 32 of the rotating member 3 and the groove opening of the annular groove 5 form a separation cavity. The separation outlet 33 on the rotating member 3 connects to the groove 32, so the separation outlet 33 also connects to the separation cavity. The spiral ring 31 of the rotating member 3 is located in the separation chamber and is rotatably sleeved on the connecting member 1. When the rotating member 3 rotates relative to the connecting member 1, the spiral ring 31 rotates relative to the connecting member 1, squeezing the solid-liquid mixture flowing out from the extrusion hole 12 and adhering to the outer peripheral wall of the connecting member 1, separating the liquid in the solid-liquid mixture. The liquid can flow out from the drain hole 21 of the isolation member 2, and the solid in the solid-liquid mixture squeezed and separated by the spiral ring 31 enters the separation outlet 33. Since the rotating member 3 is rotating during the solid-liquid separation process, the solid flowing out from the separation outlet 33 of the rotating member 3 also has rotational inertia. The support member 4 is rotatably engaged with the rotating member 3 and is sleeved on the connecting member 1. The liquid chamber 41 of the support member 4 can collect the liquid flowing out from the drain hole 21, and the solid chamber 42 of the support member 4 can accommodate part of the rotating member 3. The rotating member 3 is inserted into the through hole 43 and abuts against the isolation member 2. The rotating member 3 can be supported and can play a certain role in isolating the liquid chamber 41 and the solid chamber 42. The solid chamber 42 is connected to the separation outlet 33. The solid chamber 42 can accommodate and collect the solid flowing out from the separation outlet 33, thus completing the separation of the solid and liquid in the solid-liquid mixture. The solid-liquid mixture is separated by the extrusion of the spiral ring 31, resulting in good separation efficiency and stability. The solid-liquid mixture will not be damaged by impacting the connecting parts 1, etc., and frequent maintenance of the solid-liquid separation equipment is not required, which can reduce the maintenance cost of the solid-liquid separation equipment and solve the technical problem of high maintenance cost of solid-liquid separation equipment to a certain extent.

[0047] Furthermore, the solid-liquid separation equipment in this application has almost no difference in separation efficiency for solid-liquid mixtures compared to centrifuges. However, the solid-liquid separation equipment in this application requires less maintenance than centrifuges, significantly reducing maintenance costs. The solid-liquid separation equipment in this application also has a simpler structure, which helps reduce preparation costs. It is also more compact, which helps reduce the overall space required for the solid-liquid separation equipment. The solid-liquid separation equipment in this application can be used to separate solid-liquid mixtures such as protein whey.

[0048] It should be noted that the barrel-shaped connector 1 is a cylindrical structure with one end open and the other end closed. The solid-liquid mixture enters the inner hole 11 of the connector 1 from the open end. The groove 32 and the annular groove 5 align to form a separation cavity. Figure 1 The separation chamber was not marked in the text. Figure 1 The annular groove 5 and the groove 32 that form the separation cavity are marked in the middle.

[0049] In some or all embodiments, the closed end of the connector 1 abuts against the bottom of the groove 32, the separation cavity is an annular cavity surrounding the connector 1, the spiral ring 31 extends from one end of the annular cavity to the other end of the annular cavity, and the cross-sectional area of ​​the annular cavity decreases in the direction A of the separator 2 pointing to the groove 32.

[0050] One closed end of the connector 1 abuts against the bottom of the groove 32. The separation chamber is an annular cavity surrounding the connector 1. The spiral ring 31 extends from one end of the annular cavity to the other end. This allows for a larger contact area between the spiral ring 31 and the outer peripheral wall of the connector 1, enabling sufficient compression of the solid-liquid mixture flowing out of the outer peripheral wall of the connector 1. This facilitates the separation of the liquid and solid components in the solid-liquid mixture. Furthermore, in the direction A from the separator 2 towards the groove 32, the cross-sectional area of ​​the annular cavity decreases, and the annular cavity tends to contract near the rotating member 3. The reduced space of the annular cavity further compresses the liquid in the solid-liquid mixture, effectively separating the liquid from the solid. The spiral ring 31 also compresses the solid in the solid-liquid mixture into the space of the groove 32 of the rotating member 3, and then collects it through the separation outlet 33 connecting the groove 32. This completes the solid-liquid separation of the solid-liquid mixture and achieves effective collection of the solid.

[0051] It should be noted that when the closed end of the connector 1 abuts against the bottom of the groove 32, and the groove 32 of the rotating member 3 aligns with the annular groove 5, a separation cavity naturally forms around the connector 1, and this naturally formed separation cavity is an annular cavity. The cross-section of the annular cavity is the cross-section obtained by cutting a plane that forms an angle with the axis of the annular groove 5. The area of ​​the cross-section of the annular cavity can be reduced by changing the outer diameter of the connector 1, or by changing the shape or width of the groove 32 of the rotating member 3, or by changing the width of the inner circumferential wall of the isolator 2 corresponding to the annular groove 5. For ease of understanding, in Figure 2 The direction AA of the spacer 2 pointing to the groove 32 is shown. The direction A of the spacer 2 pointing to the groove 32 can also be the axial direction of the connector 1.

[0052] In some or more embodiments, a certain gap may exist between the other end of the connector 1 and the rotating member 3. The cross-sectional area of ​​the separation cavity formed by the docking of the isolator 2 and the rotating member 3 may also decrease in stages in the direction A of the isolator 2 pointing towards the groove 32. The spiral ring 31, in conjunction with the change in the cross-sectional area of ​​the separation cavity, can also separate the solid-liquid mixture, and squeeze the solid into the groove 32 of the rotating member 3, and then flow from the groove 32 into the separation outlet 33.

[0053] In some or more embodiments, the inner peripheral wall of the spiral ring portion 31 abuts against the outer peripheral wall of the connector 1, and the outer peripheral wall of the spiral ring portion 31 abuts against the spacer 2.

[0054] The inner peripheral wall of the spiral ring 31 abuts against the outer peripheral wall of the connector 1, and the outer peripheral wall of the spiral ring 31 abuts against the separator 2. When the spiral ring 31 rotates relative to the connector 1, the solid-liquid mixture can be squeezed and separated between the spiral ring 31 and the connector 1, and between the spiral ring 31 and the separator 2. This is beneficial to improving the efficiency of the squeeze separation and also to squeezing the solid into the groove 32 of the rotating member 3.

[0055] It should be noted that the inner peripheral wall of the spiral ring 31 is the side wall of the spiral ring 31 corresponding to its own inner diameter, and the outer peripheral wall of the spiral ring 31 is the side wall of the spiral ring 31 corresponding to its own outer diameter.

[0056] In some or more embodiments, the inner peripheral wall of the spiral ring 31 may abut against the connector 1, and there may be a gap between the outer peripheral wall of the spiral ring 31 and the spacer 2. Alternatively, the outer peripheral wall of the spiral ring 31 may abut against the spacer 2 at different positions along its axial direction, or it may not abut against it. Extrusion separation can also be achieved.

[0057] In some or more embodiments, the connector 1 is provided with a plurality of extrusion holes 12 spaced apart along its own circumference, the diameter of the extrusion holes 12 being smaller than the inner diameter of the connector 1.

[0058] The connector 1 has multiple extrusion holes 12, which facilitates the flow of solid-liquid mixture from the inner hole 11 of the connector 1 to the outer peripheral wall of the connector 1. The diameter of the extrusion hole 12 is smaller than that of the inner hole 11 of the connector 1. When the solid-liquid mixture flows from the inner hole 11 of the connector 1 into the extrusion hole 12, the solid in the solid-liquid mixture can also be squeezed, which can also play a certain separation role.

[0059] In some or more embodiments, the rotating member 3 may further include:

[0060] The shaft 34 is rotatably inserted into the support member 4 and extends into the solid cavity 42;

[0061] The docking part 35 is connected to the shaft part 34 and is located in the solid cavity 42. The groove 32 and the separation outlet 33 are both provided in the docking part 35. The spiral ring part 31 is connected to the docking part 35 and is located in the groove 32.

[0062] The shaft portion 34 of the rotating member 3 mates with the support member 4. The shaft portion 34, which is inserted into the solid cavity 42, can also be used to connect the docking portion 35, providing an installation position for the docking portion 35. The docking portion 35, in turn, provides an installation position for the spiral ring portion 31. When the shaft portion 34 rotates, it can drive the docking portion 35 and the spiral ring portion 31 to rotate together, so that the spiral ring portion 31 rotates relative to the connecting member 1, thereby separating the solid-liquid mixture flowing out from the outer peripheral wall of the connecting member 1.

[0063] In some or more embodiments, the docking portion 35 may be a conical tube with a smaller diameter and closed at one end. The closed end of the docking portion 35 is sleeved and fixed to the shaft portion 34. The flared inner hole 11 of the docking portion 35 may form a groove 32. One end of the spiral ring portion 31 may be connected to the docking portion 35, and the other end may be located in the groove 32. The closed end of the connector 1 may also extend into the groove 32. The spiral ring portion 31 may be sleeved on the connector 1 or may extend into the annular groove 5 between the separator 2 and the connector 1. In this configuration, when the solid extruded by the spiral ring portion 31 rotates relative to the connector 1 and enters the groove 32 of the rotating member 3, the groove 32 has a radial contraction tendency, which can squeeze the solid from the separation outlet 33 into the solid cavity 42.

[0064] In some or more embodiments, the solid-liquid separation device may also include a first drive assembly (not shown in the figure). The first drive assembly may include a motor and a gearbox. The output shaft of the motor may be connected to the input shaft of the gearbox, and the output shaft of the gearbox may be connected to the shaft portion 34. The shaft portion 34 can be driven to rotate, thereby driving the docking portion 35 and the spiral ring portion 31 to rotate, achieving extrusion separation.

[0065] In some or more embodiments, the support member 4 is provided with a solid outlet 44 communicating with the solid cavity 42, and the rotating member 3 further includes:

[0066] The fan blade portion 36 is connected to the docking portion 35 and protrudes from the docking portion 35. The fan blade portion 36 is located in the solid cavity 42.

[0067] When the rotating member 3 rotates, the fan blade 36 can stir the solid entering the solid cavity 42, facilitating the flow of the solid out of the solid outlet 44 that connects to the solid cavity 42. This promotes the outflow of the solid and allows it to be collected into a dedicated container or device for storage.

[0068] In some or more embodiments, at least two fan blades 36 may be connected to the outer peripheral wall of the conical docking portion 35, and the fan blades 36 may be spaced apart from the separation outlet 33. This promotes higher efficiency in solid discharge.

[0069] refer to Figure 2 In some embodiments, the spacer 2 may also be barrel-shaped, with its closed end fitted onto the connector 1. An annular groove 5 may be formed between the closed end of the spacer 2, the inner peripheral wall of the spacer 2, and the outer peripheral wall of the connector 1. The inner diameter of the open end of the spacer 2 is smaller than that of the closed end. The spiral ring 31 may extend into the annular groove 5, enabling rotational engagement with the connector 1.

[0070] In some or more embodiments, the isolation member 2 may be barrel-shaped, with one closed end of the isolation member 2 sleeved on the connecting member 1, and the open end of the isolation member 2 abutting against the rotating member 3. The outer peripheral wall of the isolation part may be connected to the support member 4, and multiple drainage holes 21 may be arranged along the circumference of the isolation member 2 on the isolation body, with the drainage holes 21 penetrating the isolation body. This improves stability and facilitates drainage.

[0071] In some or more embodiments, the support member 4 is provided with an outlet (not shown) communicating with the liquid chamber 41. Liquid entering the liquid chamber 41 can then be discharged from the outlet.

[0072] In some or more embodiments, the support member 4 may include an annular portion 46 and a cylindrical body 45 closed at both ends. The annular portion 46 is plate-shaped and coaxially connected to the inner peripheral wall of the cylindrical body 45, separating the inner hole 11 of the cylindrical body 45 into a liquid cavity 41 and a solid cavity 42 at both ends. The inner hole 11 of the annular portion 46 is configured as a through hole 43. One end of the cylindrical body 45 can be fitted with a connecting member 1, and the other end of the cylindrical body 45 is rotatably fitted with a rotating member 3. Both the solid outlet 44 and the water outlet can be located on the cylindrical body 45. This facilitates installation and preparation. The annular portion 46 can also be connected to the isolator 2 to improve the support effect on the isolator 2.

[0073] Figure 2 This application shows a schematic diagram of the structure of another solid-liquid separation device in some embodiments or certain embodiments. Figure 3 This application shows an assembly diagram of a mounting component and a screw in some or certain embodiments, with reference to... Figure 2 , 3 In some or more embodiments, the solid-liquid separation device further includes:

[0074] Mounting component 6 is provided with a chamber 61 and an inlet 62 and an outlet that connect to the chamber 61. The inlet 62 is for the solid-liquid mixture to flow in, and the outlet is connected to the inner hole 11 of the connector 1.

[0075] The screw 7 is rotatably inserted into the mounting 6 and inserted into the chamber 61. The screw 7 is configured to rotate relative to the mounting 6 to extrude the solid-liquid mixture to the outlet.

[0076] The solid-liquid mixture can enter the chamber 61 of the mounting component 6 through the inlet 62. In the chamber 61 of the mounting component 6, it is squeezed by the rotating screw 7 to the outlet of the connecting chamber 61. During the process of the screw 7 squeezing the solid-liquid mixture, some of the liquid in the solid-liquid mixture can be squeezed out, which plays a preliminary separation role. The solid-liquid mixture that has completed the preliminary separation by the screw 7 then enters the connecting component 1 and the isolation component 2 in sequence, and is squeezed and separated again by the spiral ring part 31. The screw 7 and the spiral ring part 31 can perform secondary separation of the solid-liquid mixture, which is beneficial to improving the separation efficiency and separation effect of the solid-liquid mixture.

[0077] In some or more embodiments, mounting component 6 may include:

[0078] The mounting body 64 has a cylindrical hole and an inlet 62. The inlet 62 is connected to one end of the cylindrical hole, and the outlet 63 is connected to the other end of the cylindrical hole. The screw 7 is rotatably inserted into the mounting body 64, and the screw 7 is threadedly engaged with the hole wall of the cylindrical hole.

[0079] The connecting part 65 is provided with a discharge groove 651 and an outlet 63. The discharge groove 651 is connected to the other end of the cylindrical hole and forms a chamber 61 with the cylindrical hole. The inner hole 11 of the connecting member 1 is connected to the outlet 63.

[0080] Mounting component 6 adopts the above structure, which facilitates its processing and preparation. The screw 7, through rotation, can also expel solids into the discharge groove 651, where a certain amount of solid-liquid mixture is collected. Finally, the solid-liquid mixture enters the inner hole 11 of the connector 1 from the outlet 63 connecting to the discharge groove 651. The screw 7 can also be a carbon steel screw 7, which has high strength and good wear resistance. The open end of the connector 1 can be inserted into the outlet 63 of the connecting part 65, and the connector 1 is fixed to the connecting part 65. This facilitates the entry of the solid-liquid mixture into the inner hole 11 of the connector 1. There can be one screw 7 or two screws arranged in parallel.

[0081] In some or more embodiments, the mounting body 64 may also be provided with a drain outlet 66 that communicates with the cylindrical hole, and the drain outlet 66 and the inlet 62 are located at the same end of the cylindrical hole. The liquid squeezed out by the rotation of the screw 7 to compress the solid-liquid mixture can also flow out from the drain outlet 66.

[0082] In some or all embodiments, the mounting component 6 may also consist only of the mounting body 64, with one end of the cylindrical hole connected to the outlet 8263 and the other end connected to the inner hole 11 of the connector 1. This can also facilitate the transfer of solid-liquid mixtures.

[0083] In some or more embodiments, the solid-liquid separation device may also include a second drive assembly (not shown in the figure). The configuration of the second drive assembly can refer to that of the first drive assembly, and the output shaft of the gearbox in the second drive assembly can be connected to the screw 7. This allows the screw 7 to rotate relative to the mounting member 6.

[0084] In some or more embodiments, the solid-liquid separation apparatus may further include:

[0085] The filter element 8 is provided with a filter tank 81 and an outlet 82. The opening of the filter tank 81 is for the solid-liquid mixture to flow in, and the outlet 82 is connected to the filter tank 81 and the outlet 82 is connected to the inlet 62.

[0086] The filter screen 9 is connected to the filter element 8 and is located between the opening of the filter tank 81 and the outlet 82.

[0087] The filter element 8 and the filter screen 9 can filter the solid-liquid mixture, so that large particulate impurities in the solid-liquid mixture are filtered out and then enter the mounting cavity of the mounting element 6 for subsequent separation. On the one hand, this can improve the quality of the separated solids, and on the other hand, it can reduce the possibility of impurities in the solid-liquid mixture, reduce the possibility of impurities affecting or damaging the mounting element 6 or the connecting element 1, and reduce the possibility of maintenance required for the solid-liquid separation equipment.

[0088] It should be noted that the outlet 82 of the filter element 8 and the inlet 62 of the mounting element 6 can be connected through the pipe or hose hole.

[0089] In some or more embodiments, the solid-liquid separation apparatus may further include:

[0090] The vibration motor 100 is connected to the filter element 8 and spaced apart from the filter tank 81.

[0091] A vibration motor 100 is connected to the filter element 8 and spaced apart from the filter tank 81. The vibration motor 100 in the filter assembly can rotate to drive the filter element 8 to vibrate. The vibration superimposed on the screening of the filter screen 9 is beneficial to improving the filtration effect on the solid-liquid mixture and reducing large particulate impurities in the solid-liquid mixture.

[0092] It should be noted that the vibrating motor 100 housing is idle, and the vibrating motor 100 vibrates during the rotation process and transmits the vibration to the filter element 8.

[0093] In some or more embodiments, the filter element 8 may be a stainless steel container, possessing high strength and good toughness, capable of withstanding the weight of the entire separation device as well as the vibration and impact forces generated during operation. The wall of the filter tank 81 of the filter element 8 may be connected to a polyoxymethylene mounting plate 83, and the filter screen 9 is fixed to the polyoxymethylene mounting plate 83. It offers good wear resistance and fixation.

[0094] In some or more embodiments, the filter assembly may further include a support 200 and a plurality of aluminum alloy connecting plates 300 and springs 400. The plurality of aluminum alloy connecting plates 300 are spaced apart from the container, and each aluminum alloy connecting plate 300 is connected to one end of a spring 400, the other end of which can be sleeved on the support 200. This improves stability and reduces the impact on the filter element 8 when using the vibration motor 100. The lighter aluminum alloy connecting plates 300 also help to reduce the overall weight.
