Description

Technical Field

[0001] This utility model relates to the field of Roots vacuum pump technology and belongs to an end plate sealing structure. Background Technology

[0002] An end-plate seal is a device used to seal the ends of pipes, containers, or equipment to ensure a tight seal and prevent media leakage or the entry of external contaminants. It is widely used in industries such as chemical, petroleum, power, and pharmaceutical, especially in high-pressure, high-temperature, or corrosive environments. Existing end-plate seals are typically made of metal or composite materials, possessing sufficient strength and corrosion resistance. Sealing elements are used to fill the gap between the end plate and the connecting components to ensure a seal. Fasteners, such as bolts and nuts, are then used to secure the end plate and apply pressure to ensure a tight fit of the sealing elements. Some end-plate seals also have interfaces or openings for connecting pipelines to facilitate material transport.

[0003] For example, a self-sealing end plate with prior art disclosure number CN214714866U includes an end cap body, a rubber ring 1 to ensure a good seal between the end cap body and the base, an inner sealing plate fixed to the bottom inner side of the outer edge of the end cap body, and rubber rings 2, 3 and 4 on the outer side of the inner sealing plate to ensure a foolproof seal between the base and the end cap body.

[0004] However, the existing technology described above still has the following problems in use: When the traditional end plate is fixed with bolts, the membrane module will vibrate during use. When the vibration is transmitted to the end plate, it will cause the bolts to loosen. After long-term use, it will affect the connection between the end plate and the membrane module, as well as the sealing performance between them, and leakage problems are likely to occur. Based on this, this utility model provides an end plate sealing structure with high sealing performance. Utility Model Content

[0005] Therefore, this utility model provides an end plate sealing structure to solve the problem in the prior art where bolts loosen due to end plate vibration, which in turn affects the end plate connection firmness and sealing performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An end plate sealing structure includes an end plate body. An annular groove is formed at the bottom of the end plate body. An annular plate and a rubber sealing ring are arranged vertically inside the annular groove. Multiple fastening bolts arranged in a circular array penetrate the outer wall of the end plate body. A reinforcing assembly for reinforcing the annular plate and fastening bolts is provided at the top of the end plate body. The reinforcing assembly includes a top plate. Multiple connecting rods and multiple reinforcing rods are fixedly provided at the bottom of the top plate. The bottom ends of the connecting rods penetrate the top of the end plate body and are fixedly connected to the top of the annular plate. The bottom ends of the reinforcing rods penetrate the end plate body and abut against the top of the fastening bolts.

[0008] Furthermore, the top of the end plate body is provided with multiple through holes that are adapted to the connecting rod and the reinforcing rod. The connecting rod and the reinforcing rod pass through the multiple through holes respectively. By setting multiple through holes for the use of the connecting rod and the reinforcing rod, the connecting rod and the reinforcing rod can also be limited, thereby providing stability for their lifting and lowering.

[0009] Furthermore, the top plate has four openings, each with a connector inside. The bottom end of the connector extends through the top of the end plate body to the outside of the end plate body. Each connector has a fixing component to provide stability to the connector.

[0010] Furthermore, the fixing assembly includes two detachably connected clamps, which are fitted onto the outer wall of the connector. Each opening has a groove on its inner wall, and the clamps are slidably disposed in the grooves. By clamping the two clamps onto the outer wall of the connector, the stability of the connector can be further improved.

[0011] Furthermore, the outer wall surface of the end plate body is machined with a plurality of mounting holes arranged in a ring array. The mounting holes are connected to the through holes, and the fastening bolts are located in the mounting holes to house the fastening bolts and prevent them from being exposed and loosened by collisions.

[0012] Furthermore, an electric push rod is connected between the bottom of the top plate and the top of the end plate body. There are multiple electric push rods, which are evenly distributed at the bottom of the top plate.

[0013] Furthermore, the top of the end plate body is machined with the same number of mounting slots as the electric push rods. The electric push rods can be detachably installed in the mounting slots. The mounting slots can improve the stability of the electric push rods, thereby making the electric push rods more stable when driving the top plate to rise and fall.

[0014] Furthermore, a second rubber sealing ring is provided between each connecting rod and the through hole, and between each fastening bolt and the mounting hole. The second rubber sealing ring can improve the sealing performance between the fastening bolt and the mounting hole.

[0015] This utility model has the following advantages:

[0016] 1. This utility model improves the sealing performance of the end plate body by using a rubber sealing ring and fixing it with multiple fastening bolts, thereby improving the stability and pressure resistance of the end plate body. At the same time, the electric push rod and top plate drive the connecting rod, ring plate and reinforcing rod to move downward. The downward movement of the ring plate compresses the rubber sealing ring, which can further enhance the sealing effect. The downward movement of the reinforcing rod against the fastening bolts can further improve the stability. It can effectively prevent the fastening bolts from loosening due to the vibration of the membrane assembly, thus ensuring that the stability and sealing performance of the end plate body are not affected.

[0017] 2. By setting multiple connectors, the membrane module can be connected to the inlet pipe, concentrate pipe, outlet pipe, etc., to ensure the normal operation of the membrane module. In addition, two clamps are set in each opening to clamp the outer wall of the connector, which can further improve the stability of the connector. Attached Figure Description

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Refer to the instruction manual appendix Figures 1-5 This utility model provides an end plate sealing structure, including an end plate body 1, an annular groove 2 at the bottom of the end plate body 1, annular plates 3 and rubber sealing rings 4 distributed vertically inside the annular groove 2, and multiple fastening bolts 5 arranged in an annular array through the outer wall of the end plate body 1.

[0030] The top of the end plate body 1 is provided with a reinforcing component 6 for reinforcing the ring plate 3 and the fastening bolts 5. The reinforcing component 6 includes a top plate 61. Multiple connecting rods 62 and multiple reinforcing rods 63 are fixedly provided at the bottom of the top plate 61. The bottom ends of the multiple connecting rods 62 all penetrate the top of the end plate body 1 and are fixedly connected to the top of the ring plate 3. The bottom ends of the multiple reinforcing rods 63 all penetrate the end plate body 1 and abut against the top of the fastening bolts 5. Specifically, multiple through holes 7 adapted to the connecting rods 62 and the reinforcing rods 63 are opened on the top of the end plate body 1. The connecting rods 62 and the reinforcing rods 63 respectively pass through the multiple through holes 7. A rubber sealing ring 14 is provided between each connecting rod 62 and the through hole 7.

[0031] Furthermore, multiple electric push rods 12 are connected between the bottom of the top plate 61 and the top of the end plate body 1. These electric push rods 12 are evenly distributed at the bottom of the top plate 61. By extending and retracting the electric push rods 12, the top plate 61 is moved up or down, thereby automatically pressurizing the rubber sealing ring 4 and the fastening bolt 5. At the same time, the same number of mounting grooves 13 as the electric push rods 12 are machined on the top of the end plate body 1. The electric push rods 12 can be detachably installed in the mounting grooves 13. Installing the electric push rods 12 in the mounting grooves 13 can improve the stability of the electric push rods 12, thus making the lifting and lowering of the top plate 61 more stable when driven by the electric push rods 12.

[0032] In actual use, the operator first accurately places the end plate body 1 onto the top or bottom of the membrane module, and then tightens multiple fastening bolts 5 to secure it. It can withstand a pressure of 20 MPa. Simultaneously, the rubber sealing ring 4 inside the end plate body 1 acts as a seal between the end plate body 1 and the membrane module, effectively preventing liquid or gas leakage. Then, multiple electric push rods 12 are shortened, causing the connected top plate 61 to move downwards. Multiple connecting rods 62 connected to the bottom of the top plate 61 move the ring plate 3 downwards as well. During the downward movement of the ring plate 3, it exerts a squeezing effect on the rubber sealing ring 4, further enhancing the sealing effect of the rubber sealing ring 4 and ensuring more reliable sealing performance. Meanwhile, multiple reinforcing rods 63, driven by the downward movement of the top plate 61, are inserted into the pre-set through holes 7 on the end plate body 1. The lower ends of the multiple reinforcing rods 63 abut against the tops of multiple fastening bolts 5, which can further improve the stability of the fastening bolts 5 to a certain extent. When the membrane module vibrates during operation, the rubber sealing ring 4 can remain tightly fitted to the membrane module under the pressure of the ring plate 3, while the multiple fastening bolts 5 remain stable under the restriction of the reinforcing rods 63. This can effectively prevent the fastening bolts 5 from loosening due to the vibration of the membrane module, thereby ensuring that the stability and sealing of the end plate body 1 are not affected, and ensuring that the entire membrane module system can operate continuously and stably.

[0033] In this embodiment, a plurality of mounting holes 11 arranged in a ring array are machined on the outer side wall surface of the end plate body 1. The mounting holes 11 are connected to the through holes 7 used by the reinforcing rod 63. The fastening bolt 5 is located in the mounting holes 11, and a rubber sealing ring 2 14 is provided between the fastening bolt 5 and the mounting hole 11 to house the fastening bolt 5 in the mounting hole 11, preventing the fastening bolt 5 from being exposed and loosened due to collision. At the same time, the rubber sealing ring 2 14 can improve the sealing between the fastening bolt 5 and the mounting hole 11.

[0034] Refer to the instruction manual appendix Figures 1-5The top plate 61 has four openings 8 at the top, and each opening 8 has a connector 9 inside. The bottom end of the connector 9 extends through the top of the end plate body 1 to the outside of the end plate body 1. Each connector 9 is provided with a fixing component 10. Specifically, the fixing component 10 includes two detachably connected clamps 101. The two clamps 101 are fitted on the outer wall of the connector 9. Each opening 8 has a groove 102 on its inner wall, and the clamps 101 are slidably disposed in the groove 102.

[0035] By setting multiple connectors 9 for connecting the inlet pipe, concentrate pipe, outlet pipe, etc. required by the membrane module, the normal operation of the membrane module is ensured. In addition, two clamps 101 are set in each opening 8, which are clamped to the outer wall of the connector 9 to further improve the stability of the connector 9.

[0036] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
