Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for a deaerator. Background Technology

[0002] With the rapid development of technology, degassing machines, as indispensable equipment in precision manufacturing processes, directly affect the quality and market competitiveness of downstream products. Especially in key fields such as electronic materials, chemicals, and food processing, filtering impurities from the production slurry is a crucial step in the operation of degassing machines. Efficiently removing bubbles and impurities from the slurry ensures the uniformity and surface smoothness of the final product, which is an important means to improve product yield and reduce costs. However, most of the filters used in existing degassing machines rely on imports from Japan. Although this meets the demand for high-precision filtration to some extent, its inherent limitations are becoming increasingly prominent, becoming a bottleneck restricting the further development of the industry.

[0003] On the one hand, the procurement process for these imported filters is currently complex and the supply channels are unstable, involving many aspects of international trade, such as customs declaration and inspection. This results in long delivery cycles and poor supply stability, bringing great uncertainty and risk to enterprises' production plans and seriously affecting their production continuity and market competitiveness. On the other hand, the high procurement costs increase enterprises' production costs, compress profit margins, and reduce the market competitiveness of products. Moreover, imported filters not only have fixed filtration specifications for each filter, making them non-universal and impractical, but they are also disposable products with high consumption. Furthermore, they easily generate a large amount of solid waste during disposal, placing a heavy burden on the environment and running counter to the current global trend of advocating green, low-carbon, and circular economy development. Utility Model Content

[0004] The purpose of this utility model is to provide a filter device for a deaerator, so as to solve the problems of complex procurement, high cost, environmental non-environmental protection and low practicality of filters used in deaerators in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A filter device for a degassing machine, comprising:

[0007] The housing includes an upper housing, a lower housing, and a clamping structure. The upper housing and the lower housing are detachably connected by the clamping structure. The upper housing has a feed inlet, and the lower housing has a discharge outlet.

[0008] A filter assembly, comprising a first filter element and a second filter element, wherein the first filter element and the second filter element are sequentially installed in the lower housing from the inside to the outside along the axial direction of the housing;

[0009] A separator assembly, one end of which is installed between the upper housing and the lower housing, and the other end is supported between the first filter element and the second filter element, for isolating the first filter element and the second filter element;

[0010] An exhaust assembly, which is disposed on the upper housing, is used to exhaust air from the housing.

[0011] Based on the aforementioned technical means, the upper and lower shells are detachably connected by a clamp structure, which not only enables rapid assembly and disassembly of the entire device but also facilitates cleaning and maintenance of the internal shells. The structure is simple and easy to operate; in actual use, only the filter components need to be replaced, allowing for reuse. It is highly practical, uses readily available materials, reduces production costs, minimizes solid waste generation, and ensures environmental protection and zero pollution. Furthermore, the dual filtration structure composed of the first and second filter elements improves filtration effect and precision, ensuring product quality. The separation component further separates the first and second filter elements, creating a gap that enhances filtration efficiency and effectiveness. Simultaneously, the exhaust component allows air inside the shell to be promptly expelled, preventing air from affecting filtration efficiency and ensuring no air pockets form in the filter slurry. This effectively prevents the potential impact of air pockets on product quality, improves filtration accuracy and stability, and ultimately enhances the overall performance and effectiveness of the device.

[0012] Furthermore, the separating component includes an inner ring and an outer ring, which are integrally formed. The outer ring abuts between the upper housing and the lower housing, and the inner ring is located inside the housing and supported between the first filter element and the second filter element, for isolating the first filter element and the second filter element. The mounting end of the first filter element is configured to bypass the upper end face of the inner ring and abut between the outer ring and the upper housing, and the mounting end of the second filter element is configured to bypass the lower end face of the inner ring and abut between the outer ring and the lower housing.

[0013] Based on the aforementioned technical means, the integrated molding design of the inner and outer rings makes the structure more robust and ensures the stability and convenience of the separator assembly during installation. Specifically, during assembly, the second filter element is first placed inside the lower housing, with its mounting end bypassing the lower end face of the inner ring and extending to the space between the outer ring and the lower housing. Then, the first filter element is placed inside the second filter element, with its mounting end bypassing the upper end face of the inner ring and extending to the space between the outer ring and the upper housing. This allows the clamping structure to press the first and second filter elements into the housings respectively when fastening the upper and lower housings. The inner ring supports the first and second filter elements, creating a filtration gap between them, improving filtration efficiency and effect, facilitating the disassembly and replacement of the first and second filter elements, and ensuring high installation stability.

[0014] Furthermore, an upper convex ring is formed on the upper end face of the inner ring, the upper convex ring being configured to abut the mounting end of the bypassed first filter element against the inner wall of the upper housing, and a lower convex ring is formed on the lower end face of the inner ring, the lower convex ring being configured to abut the mounting end of the bypassed second filter element against the inner wall of the lower housing.

[0015] Based on the aforementioned technical means, by designing upper and lower convex rings on the upper and lower end faces of the inner ring respectively, a stable support point is provided for the mounting ends of the first and second filter elements. This ensures that they can be accurately positioned and tightly and firmly abutted against the inner walls of the upper and lower housings during assembly, preventing the first and second filter elements from slipping off during use, which would lead to problems such as poor filtration effect and low efficiency. This enhances the overall stability and structural strength of the filter assembly, simplifies the structure, improves working efficiency, and further enhances the overall filtration performance and durability of the device by increasing the contact area.

[0016] Furthermore, sealing rings are respectively provided between the outer ring and the upper housing, and between the outer ring and the lower housing. A first annular limiting groove is formed on the upper end face of the outer ring, and a second annular limiting groove is formed on the lower end face of the upper housing. The first annular limiting groove and the second annular limiting groove are arranged opposite to each other. One of the sealing rings is configured to be embedded in the first annular limiting groove and the second annular limiting groove. A third annular limiting groove is formed on the lower end face of the outer ring, and a fourth annular limiting groove is formed on the upper end face of the lower housing. The third annular limiting groove and the fourth annular limiting groove are arranged opposite to each other. Another sealing ring is configured to be embedded in the third annular limiting groove and the fourth annular limiting groove.

[0017] Based on the above technical means, by cooperating with the first annular limiting groove and the second annular limiting groove, and by cooperating with the third annular limiting groove and the fourth annular limiting groove, the two sealing rings can be respectively limited on the upper and lower end faces of the outer ring, realizing a stable and reliable sealing connection between the outer ring and the upper and lower housings. This improves the ease and accuracy of sealing ring installation, and also ensures the durability and consistency of the sealing effect, effectively preventing material leakage during the filtration process, thereby ensuring the overall filtration efficiency and product quality of the filtration device.

[0018] Furthermore, the exhaust assembly includes an exhaust pipe and a ball valve. One end of the exhaust pipe is connected to the upper housing, and the other end is connected to the ball valve, which is used to open and / or close the exhaust pipe.

[0019] Based on the aforementioned technical means, a flexible and efficient exhaust structure is provided for the filter device of the deaerator through the exhaust pipe and ball valve. Specifically, before the filter slurry enters the shell, the ball valve is opened and the switch below the outlet is closed, allowing the filter slurry to be injected from the inlet. This allows the air inside the shell to be smoothly discharged through the exhaust pipe, thereby avoiding the influence of air on the filtration process and improving filtration efficiency and product quality. After the air is discharged, the ball valve is closed and the switch below the outlet is opened, and normal filtration operation can begin. The exhaust operation is simple, enhancing the overall flexibility and controllability of the device and providing a strong guarantee for the efficient operation of the filter device for the deaerator.

[0020] Furthermore, the clamp structure includes a first arc-shaped component, a second arc-shaped component, a screw, and a nut. One end of the first and second arc-shaped components is rotatably connected via a first rotating shaft. The first and second arc-shaped components are respectively configured to rotate around the central axis of the first rotating shaft. The other ends of the first and second arc-shaped components are respectively formed with mounting protrusions. Notches are formed on the two mounting protrusions. One end of the screw is rotated via the second rotating shaft and installed in one of the notches, and is configured to rotate around the central axis of the second rotating shaft. The other end of the screw can pass through the other notch and be threadedly connected to the nut. The nut is configured to abut against the adjacent mounting protrusion, so that the inner walls of the first and second arc-shaped components can abut against the outer walls of the upper and lower housings, realizing a detachable connection between the upper and lower housings.

[0021] According to the above technical means, the first and second arc-shaped parts can be locked or released by the cooperation of the screw and nut, which is highly flexible and practical. Specifically, in actual application, the first and second arc-shaped parts are placed at the connection position of the upper and lower shells, so that the inner walls of the first and second arc-shaped parts are in contact with the outer walls of the upper and lower shells. The position of the screw is rotated so that the screw is locked in the two notches. Then the nut is rotated so that the nut abuts against the adjacent mounting protrusion, thereby locking the first and second arc-shaped parts to achieve the fastening installation of the upper and lower shells. The structure is simple and easy to use.

[0022] Furthermore, arcuate grooves are formed on the inner walls of the first and second arcuate components, and a first conical surface and a second conical surface are formed on the opposite sidewalls of the two arcuate grooves, respectively. A first convex ring is formed at the lower end of the upper housing, and a third conical surface is formed on the first convex ring. The third conical surface is configured to abut against the first conical surface. A second convex ring is formed at the upper end of the lower housing, and a fourth conical surface is formed on the second convex ring. The fourth conical surface is configured to abut against the second conical surface.

[0023] According to the above technical means, by having the first and second conical surfaces cooperate with the third and fourth conical surfaces respectively, under the action of the sealing ring, the connection between the upper and lower housings becomes tighter and more stable as the first and second arc-shaped parts are tightened. At the same time, the cooperation of the conical surfaces also has a certain degree of tolerance. Even if there is a slight deviation between the upper and lower housings during assembly, a good sealing and connection effect can be achieved by adjusting the conical surfaces. The structure is simple, the operation is convenient, and the assembly efficiency and sealing performance of the device are improved.

[0024] Furthermore, it also includes a feed pipe and a discharge pipe. One end of the feed pipe is connected to the feed port on the upper shell, and the other end is used to connect to the discharge port of the degassing machine. One end of the discharge pipe is connected to the discharge port of the lower shell, and the other end is used to connect to an external storage device.

[0025] Based on the aforementioned technical means, the filtration device is conveniently connected to the deaerator and external storage device through the feed pipe and discharge pipe. Specifically, in practical applications, the feed pipe is integrally formed with the upper shell, and the discharge pipe is integrally formed with the lower shell. The slurry that has undergone deaeration treatment in the deaerator can enter the shell through the feed pipe. After filtration by the filter assembly, it is discharged from the discharge pipe to the external storage device for further processing. This facilitates installation, improves the collaborative working efficiency between the filtration device, the deaerator, and subsequent processes, reduces operational difficulty and labor intensity, improves overall work efficiency and product quality, and provides strong support for industrial automation and continuous production.

[0026] Furthermore, both the first filter element and the second filter element are filter screens, and the pore size of the first filter element is larger than that of the second filter element.

[0027] According to the above technical means, both the first and second filter elements are filter screens, and the pore size of the first filter element is larger than that of the second filter element, thus realizing multi-stage filtration of the slurry and improving the filtration effect. Specifically, in practical applications, when the slurry enters the upper shell from the degasser through the feed pipe, it first passes through the first filter element. Due to the larger pore size of the first filter element, it can effectively remove large particulate impurities in the slurry, providing better conditions for subsequent filtration. Subsequently, the slurry continues to flow through the second filter element. Due to the smaller pore size of the second filter element, it can further remove tiny particles and impurities in the slurry, thereby meeting the high requirements of subsequent processes for slurry quality and ensuring product quality. The first filter element can be a 100-mesh filter screen, and the second filter element can be a 200-mesh filter screen.

[0028] Furthermore, both of the sealing rings are made of fluororubber.

[0029] Based on the above technical means, the sealing ring is made of fluororubber. Fluororubber not only has corrosion resistance, high temperature resistance, oxidation resistance, as well as good elasticity and wear resistance, it can adapt to the small gap changes between the shell and the partition components, thereby maintaining a tight sealing effect. It also has a certain anti-aging property, which can extend the service life of the sealing ring, reduce the replacement frequency, and reduce maintenance costs.

[0030] The beneficial effects achieved by this utility model are:

[0031] 1. This utility model uses a clamp structure to detachably connect the upper and lower shells, which not only enables quick assembly and disassembly of the entire device, but also facilitates cleaning and maintenance of the interior of the shell. The structure is simple and easy to operate. In actual use, only the filter components need to be replaced, which can achieve the purpose of reuse. It is highly practical, the materials are easy to obtain, reduces production costs, reduces the generation of solid waste, and ensures environmental protection and pollution-free environment.

[0032] 2. This utility model improves the filtration effect and accuracy by using a dual filtration structure composed of a first filter element and a second filter element, thus ensuring product quality. Furthermore, the first filter element and the second filter element are separated by a separator component, creating a filtration gap between them, which improves filtration efficiency and effect.

[0033] 3. This utility model enables the timely discharge of air from the housing through the exhaust component, which not only prevents air from affecting the filtration efficiency, but also ensures that no air bubbles are generated in the filter slurry. This effectively prevents the potential impact of air bubbles on product quality, improves the accuracy and stability of filtration, and thus enhances the overall performance and effectiveness of the device.

[0050] Example 1

[0051] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a filtration device for a degassing machine includes: a housing 1, comprising an upper housing 11, a lower housing 12, and a clamping structure 13, wherein the upper housing 11 and the lower housing 12 are detachably connected by the clamping structure 13, the upper housing 11 has an inlet, and the lower housing 12 has an outlet; a filter assembly 2, comprising a first filter element 21 and a second filter element 22, wherein the first filter element 21 and the second filter element 22 are sequentially installed in the lower housing 12 from the inside to the outside along the axial direction of the housing 1; a separating assembly 3, one end of which is installed between the upper housing 11 and the lower housing 12, and the other end is supported between the first filter element 21 and the second filter element 22, for isolating the first filter element 21 and the second filter element 22; and an exhaust assembly 5, which is disposed on the upper housing 11 for exhausting air from the housing 1.

[0052] In this embodiment, the upper housing 11 and the lower housing 12 are detachably connected by the clamp structure 13, which not only enables quick assembly and disassembly of the entire device, but also facilitates cleaning and maintenance of the interior of the housing 1. The structure is simple and easy to operate. The dual filtration structure composed of the first filter element 21 and the second filter element 22 improves the filtration effect and accuracy, ensuring product quality. The separation component 3 separates the first filter element 21 and the second filter element 22, improving filtration efficiency and effect. At the same time, the exhaust component 5 allows the air inside the housing 1 to be discharged in time, which not only prevents air from affecting the filtration efficiency, but also ensures that no air bubbles are generated in the filter slurry, thereby effectively preventing the potential impact of air bubbles on product quality, improving the accuracy and stability of filtration, and thus enhancing the overall performance and effectiveness of the device.

[0053] In practical applications, as a preferred embodiment of this invention, it further includes an inlet pipe 6 and an outlet pipe 7. One end of the inlet pipe 6 is connected to the inlet on the upper housing 11, and the other end is used to connect to the outlet of the degassing machine. One end of the outlet pipe 7 is connected to the outlet of the lower housing 12, and the other end is used to connect to an external storage device. The first filter element 21 and the second filter element 22 are both filter screens, and the pore size of the first filter element 21 is larger than that of the second filter element 22. The inlet pipe 6 is integrally formed with the upper housing 11, and the outlet pipe 7 is integrally formed with the lower housing 12. The first filter element 21 can be a 100-mesh filter screen, and the second filter element 22 can be a 200-mesh filter screen. Those skilled in the art will understand that... The pore sizes of the first filter element 21 and the second filter element 22 can be selected according to actual filtration requirements. Specifically, during assembly, the second filter element 22 and the first filter element 21 are placed sequentially inside the lower housing 12, with the mounting ends of the first filter element 21 and the second filter element 22 extending between the partition assembly 3 and the upper housing 11, and between the partition assembly 3 and the lower housing 12, respectively. This allows the clamping structure 13 to press the first filter element 21 and the second filter element 22 between the partition assembly 3 and the upper housing 11 and the lower housing 12, respectively, when fastening the upper housing 11 and the lower housing 12. This achieves quick, convenient, and stable installation of the first filter element 21 and the second filter element 22. The filter ends of filter element 22 are sequentially located inside the lower housing 12, completing the rapid assembly of the filter device. During production, the filter device is connected between the deaerator and an external storage device such as a slurry tank or equipment in the next process via the feed pipe 6 and the discharge pipe 7. The slurry that has undergone deaeration treatment in the deaerator can enter the housing 1 through the feed pipe 6. First, close the switch below the discharge port (not shown in the diagram), then open the exhaust assembly 5 to allow the air inside the housing 1 to be expelled from the filter slurry. After the air is expelled, close the exhaust assembly 5 and open the switch below the discharge port, allowing the filter slurry to pass through the first filter element 21 and the second filter element 22 sequentially before being discharged from the discharge pipe 7 to an external storage device such as a slurry tank or equipment in the next process. The next process involves filtering out particles with diameters exceeding a preset value from the slurry, improving filtration efficiency and effectiveness, and ensuring the quality of the finished product. To ensure the overall service life of the device and prevent corrosion, the upper shell 11, lower shell 12, and clamp structure 13 can all be made of stainless steel. During use, only the first filter element 21 and the second filter element 22 (i.e., two filter screens) need to be replaced, allowing the entire device to be reused. This reduces production costs, is highly practical, reduces solid waste generation, and is environmentally friendly. The second filter element 22 is 3-6mm away from the inner wall of the lower shell 12, and the distance between the first filter element 21 and the second filter element 22 is 5mm.

[0054] Example 2

[0055] like Figures 1-4 As shown, the difference between Example 1 and Example 2 is that:

[0056] like Figure 6 As shown, the separator 3 includes an inner ring 31 and an outer ring 32, which are integrally formed. The outer ring 32 abuts between the upper housing 11 and the lower housing 12. The inner ring 31 is located inside the housing 1 and supported between the first filter element 21 and the second filter element 22, for isolating the first filter element 21 and the second filter element 22. The mounting end of the first filter element 21 is configured to bypass the upper end face of the inner ring 31 and abut between the outer ring 32 and the upper housing 11. The mounting end of the second filter element 22 is configured to bypass the lower end face of the inner ring 31 and abut between the outer ring 32 and the lower housing 12.

[0057] In this embodiment, the integrated design of the inner ring 31 and the outer ring 32 makes the structure more robust and ensures the stability and convenience of the separator component 3 during installation. Specifically, during assembly, the second filter element 22 is first placed inside the lower housing 12, with its mounting end bypassing the lower end face of the inner ring 31 and extending between the outer ring 32 and the lower housing 12. Then, the first filter element 21 is placed inside the second filter element 22, with its mounting end bypassing the upper end face of the inner ring 31 and extending between the outer ring 32 and the upper housing 11. This allows the clamping structure 13 to press the first filter element 21 and the second filter element 22 into the housing 1 respectively when fastening the upper housing 11 and the lower housing 12. The inner ring 31 is supported between the first filter element 21 and the second filter element 22, resulting in a 5mm filtration gap between the first filter element 21 and the second filter element 22. This improves filtration efficiency and effect, facilitates the disassembly and replacement of the first filter element 21 and the second filter element 22, and ensures high installation stability.

[0058] like Figure 3 As shown, further, as a preferred embodiment of this example, the upper end face of the inner ring 31 is formed with an upper convex ring, which is configured to abut the mounting end of the bypassed first filter 21 against the inner wall of the upper housing 11, and the lower end face of the inner ring 31 is formed with a lower convex ring, which is configured to abut the mounting end of the bypassed second filter 22 against the inner wall of the lower housing 12.

[0059] In this embodiment, the upper and lower convex rings designed on the upper and lower end faces of the inner ring 31 provide stable support points for the mounting ends of the first filter element 21 and the second filter element 22, ensuring that they can be accurately positioned and tightly and firmly abutted against the inner walls of the upper housing 11 and the lower housing 12 during assembly. This prevents the first filter element 21 and the second filter element 22 from slipping off during use, which would lead to poor filtration effect and low efficiency. This enhances the overall stability and structural strength of the filter assembly 4, simplifies the structure, improves working efficiency, and further enhances the overall filtration performance and durability of the device by increasing the contact area.

[0060] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0061] Example 3

[0062] like Figures 1-4 , Figure 6 and Figure 7 As shown, the difference between Example 1 and Example 2 is as follows:

[0063] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, sealing rings 4 are respectively provided between the outer ring 32 and the upper housing 11, and between the outer ring 32 and the lower housing 12. A first annular limiting groove 321 is formed on the upper end face of the outer ring 32, and a second annular limiting groove 111 is formed on the lower end face of the upper housing 11. The first annular limiting groove 321 and the second annular limiting groove 111 are arranged opposite to each other. One sealing ring is configured to be embedded in the first annular limiting groove 321 and the second annular limiting groove 111. A third annular limiting groove 322 is formed on the lower end face of the outer ring 32, and a fourth annular limiting groove 121 is formed on the upper end face of the lower housing 12. The third annular limiting groove 322 and the fourth annular limiting groove 121 are arranged opposite to each other. Another sealing ring is configured to be embedded in the third annular limiting groove 322 and the fourth annular limiting groove 121.

[0064] In this preferred embodiment, both sealing rings are made of fluororubber, which can adapt to minute gap changes between the housing 1 and the partition component 3, thereby maintaining a tight seal, extending the service life of the sealing rings, reducing replacement frequency, and lowering maintenance costs. Through the cooperation of the first annular limiting groove 321 with the second annular limiting groove 111, and the cooperation of the third annular limiting groove 322 with the fourth annular limiting groove 121, the two sealing rings can be respectively positioned on the upper and lower end faces of the outer ring 32, achieving a stable and reliable sealing connection between the outer ring 32 and the upper housing 11 and lower housing 12. This improves the ease and accuracy of sealing ring installation, ensures the durability and consistency of the sealing effect, and effectively prevents material leakage during the filtration process, thereby guaranteeing the overall filtration efficiency and product quality of the filtration device. Specifically, during assembly, when the clamp structure 13 tightens the upper housing 1... When the outer ring 32 and the lower housing 12 are connected, the upper end face of the outer ring 32 abuts against the lower end face of the upper housing 11, so that the first annular limiting groove 321 and the second annular limiting groove 111 form a complete circular annular groove. The lower end face of the outer ring 32 abuts against the upper end face of the lower housing 12, so that the third annular limiting groove 322 and the fourth annular limiting groove 121 form another complete circular annular groove. The two sealing rings are respectively placed in one of the complete circular annular grooves. With the tightening action of the clamp structure 13, each sealing ring is pressed to achieve a seal. Those skilled in the art will understand that the mounting ends of the first filter element 21 and the second filter element 22 can extend above or below each sealing ring, so that when the clamp structure 13 is tightened, its mounting ends can be pressed into the complete circular annular groove by the sealing rings. While ensuring the overall sealing performance of the device, it also makes the installation of the first filter element 21 and the second filter element 22 more convenient and stable.

[0065] The remaining features and working principles of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

[0066] Example 4

[0067] like Figures 1-4 , Figure 6 and Figure 7 As shown, the difference between this embodiment and embodiment 1, 2, or 3 is as follows:

[0068] like Figure 2As shown, the exhaust assembly 5 includes an exhaust pipe 51 and a ball valve 52. One end of the exhaust pipe 51 is connected to the upper housing 11, and the other end is connected to the ball valve 52. The ball valve 52 is used to open and / or close the exhaust pipe 51. In this embodiment, the exhaust pipe 51 and the ball valve 52 provide a flexible and efficient exhaust structure for the filter device of the degassing machine. Specifically, before the filter slurry enters the housing 1, the ball valve 52 is opened and the switch below the outlet (not shown in the figure) is closed. The filter slurry is injected from the inlet, so that the air in the housing 1 can be smoothly discharged through the exhaust pipe 51, thereby avoiding the influence of air on the filtration process, improving filtration efficiency and product quality. After the air is discharged, the ball valve 52 is closed and the switch below the outlet is opened, and normal filtration operation can begin. The exhaust operation is simple, enhancing the overall flexibility and controllability of the device, and providing a strong guarantee for the efficient operation of the filter device of the degassing machine.

[0069] The remaining features and working principles of this embodiment are consistent with those of Embodiment 1, Embodiment 2 or Embodiment 3.

[0070] Example 5

[0071] like Figures 1-7 As shown, the difference between this embodiment and embodiment 1, 2, 3, or 4 is as follows:

[0072] like Figure 5 As shown, the clamp structure 13 includes a first arc-shaped member 131, a second arc-shaped member 132, a screw 133, and a nut 134. One end of the first arc-shaped member 131 and the second arc-shaped member 132 are rotatably connected via a first rotating shaft. The first arc-shaped member 131 and the second arc-shaped member 132 are respectively configured to rotate around the central axis of the first rotating shaft. The other end of the first arc-shaped member 131 and the second arc-shaped member 132 are respectively provided with mounting protrusions 135, and notches are respectively formed on the two mounting protrusions 135. One end of the rod 133 is rotated through a second pivot to be installed in one of the notches and is configured to rotate about the central axis of the second pivot. The other end of the screw 133 can pass through another notch and be threadedly connected to the nut 134. The nut 134 is configured to abut against the adjacent mounting protrusion 135 so that the inner walls of the first arc-shaped member 131 and the second arc-shaped member 132 can abut against the outer walls of the upper housing 11 and the lower housing 12, thereby realizing the detachable connection between the upper housing 11 and the lower housing 12.

[0073] In this embodiment, the first arc-shaped component 131 and the second arc-shaped component 132 can be locked or released through the cooperation of the screw 133 and the nut 134. This provides high flexibility and practicality. Specifically, in actual application, the first arc-shaped component 131 and the second arc-shaped component 132 are placed at the connection position between the upper housing 11 and the lower housing 12, so that the inner walls of the first arc-shaped component 131 and the second arc-shaped component 132 are in contact with the outer walls of the upper housing 11 and the lower housing 12. The position of the screw 133 is rotated so that the screw 133 is locked in the two notches. Then, the nut 134 is rotated so that the nut 134 abuts against the adjacent mounting protrusion 135, thereby locking the first arc-shaped component 131 and the second arc-shaped component 132 to achieve the fastening installation of the upper housing 11 and the lower housing 12. The structure is simple and easy to use.

[0074] like Figure 3 As shown, arcuate grooves 1311 are formed on the inner walls of the first arcuate member 131 and the second arcuate member 132, respectively. A first conical surface 1312 and a second conical surface 1313 are formed on the opposite side walls of the two arcuate grooves 1311, respectively. A first convex ring 112 is formed at the lower end of the upper housing 11. A third conical surface 1121 is formed on the first convex ring 112. The third conical surface 1121 is configured to abut against the first conical surface 1312. A second convex ring 122 is formed at the upper end of the lower housing 12. A fourth conical surface 1221 is formed on the second convex ring 122. The fourth conical surface 1221 is configured to abut against the second conical surface 1313.

[0075] In this embodiment, the first conical surface 1312 and the second conical surface 1313 cooperate with the third conical surface 1121 and the fourth conical surface 1221 respectively. With the cooperation of the sealing ring 4, the connection between the upper shell 11 and the lower shell 12 becomes tighter and more stable as the first arc-shaped part 131 and the second arc-shaped part 132 are tightened. At the same time, the cooperation of the conical surfaces also has a certain degree of tolerance. Even if there is a certain slight deviation between the upper shell 11 and the lower shell 12 during assembly, a good sealing and connection effect can be achieved by adjusting the conical surfaces. The structure is simple, the operation is convenient, and the assembly efficiency and sealing performance of the device are improved.

[0076] The remaining features and working principles of this embodiment are consistent with those of Embodiment 1, Embodiment 2, Embodiment 3 or Embodiment 4.
