Description

Technical Field

[0001] The utility model relates to the technical field of pump equipment, in particular to a multi-flow vacuum pump and a vacuum pump plug. Background Art

[0002] Vacuum pumps are widely used in high-end manufacturing, scientific research, medical and pharmaceutical industries. With the development of fluid technology and the improvement of technical standards in various industries, the performance requirements for vacuum pumps are becoming higher and higher. Small size, large flow rate and stable output have become important indicators of vacuum pump performance.

[0003] Upon investigation, the Chinese utility patent with publication number CN220929609U discloses a multi-flow vacuum pump and a vacuum pump plug, wherein the multi-flow vacuum pump includes a motor, a compression chamber, an eccentric rotor, a cylinder body, a cylinder head, and a gas inlet and outlet channel is provided on one side of the compression chamber; the cylinder body is arranged outside the compression chamber, and the cylinder body cover is arranged at the port of the channel; the cylinder head cover is arranged on the cylinder body, and the cylinder head is provided with a number of ventilation interfaces, and the opening directions of the several ventilation interfaces are not all the same. By adding a cylinder head to the vacuum pump itself, replacing the external adapter accessories, and realizing multiple ventilation interfaces, the output and input gases can realize multiple flow directions to meet various working scenarios with flow requirements, and the cylinder head itself makes the volume cavity larger, has a certain buffering effect on the gas, and the flow is more stable. At the same time, the adaptation cost and leakage risk of the accessories are eliminated, and the output effect is better. Although this solution achieves multiple flow directions by installing a cylinder head with several ventilation interfaces to reduce the adaptation cost of accessories, the vacuum pump is used in different scenarios, and the plug cannot be inserted into the interface for sealing. If the vacuum pump that transmits solid fluids is used to transmit parylene gas in the medical field, the plug that other interfaces do not have will not penetrate deep into the interface to seal, and the vacuum pump will not thoroughly clean the area, which will cause trace impurities to be brought into the deposition chamber, and may also react with the parylene monomer or be doped into the coating, causing coating contamination.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The utility model provides a multi-flow vacuum pump and a vacuum pump plug, such as Figure 1-6 As shown, the vacuum pump plug includes a compression chamber, and a plurality of connection mechanisms 5 are arranged on the compression chamber;

[0038] The connecting mechanism 5 includes a mounting plate 51, which is fixedly connected to the upper end of the compression chamber by bolts. A plurality of movable rods 56 are installed inside the compression chamber. The movable rods 56 are movably connected to columns 54, and the number of columns 54 is equal to that of movable rods 56. The plurality of columns 54 are all installed on the upper end of the fixed plate 53. A sealing seat 59 is installed on the upper end of the fixed plate 53. A feed column 55 is installed on the upper end of the sealing seat 59. A feed port 58 is provided on the feed column 55.

[0039] Furthermore, the sealing seat 59 is used to seal the interface pipe body 52 by utilizing the cooperation of the column 54, the movable rod 56 and the spring 57. The pipeline of the unused interface is sealed at this time, and the sealing position is flush with the inner wall of the compression chamber. The material will not enter the pipeline of the interface. At the same time, the outside of the interface is secondary sealed by the plug cover 4 with the barrel frame 9. Compared with the traditional plug, the overall sealing is better. The column 54 and the movable rod 56 are each provided with six groups. When the feed column 55 is squeezed, the column 54 will move downward at the movable rod 56.

[0040] A cavity is formed inside the column 54, and a spring 57 is installed inside the cavity. The upper end of the spring 57 is connected to the lower end of the movable rod 56. The upper end of the mounting plate 51 is installed with an interface tube 52. The feed column 55 is located inside the interface tube 52. The upper end of the interface tube 52 is provided with a plug cover 4, and the side of the plug cover 4 is installed with a positioning assembly 6.

[0041] Furthermore, a spring 57 is installed inside the column 54. When the external pipe interface is connected to the interface pipe body 52, the feed column 55, the sealing seat 59 and the fixed plate 53 are pushed into the compression chamber. The spring 57 can reset the fixed plate 53 to a flush sealing position when the connected pipes are disassembled later.

[0042] The positioning assembly 6 includes a protrusion 61, and two groups of protrusions 61 are provided, and the two groups of protrusions 61 are symmetrically distributed at the center of the plug cover body 4. A limiting arc groove 63 is provided at one end of the positioning assembly 6 away from the plug cover body 4. A support frame is installed at the upper end of the mounting plate 51, and a lock seat 62 is installed at the upper end of the support frame. The upper end of the lock seat 62 is rotatably connected with a hook, and the hook is adapted to the limiting arc groove 63.

[0043] Furthermore, when the plug cover 4 is sealed with the interface pipe body 52, the protrusions 61 at both ends are first aligned with the lock seats 62 on the mounting plate 51, and the hooks are manually rotated and adjusted and hung on the limiting arc groove 63 to fix them, which is convenient for disassembly and assembly.

[0044] A sealing ring 7 is installed at the lower end of the plug cover 4, and a barrel frame 9 is installed at the lower end of the sealing ring 7. The outer portion of the barrel frame 9 is provided with a non-woven fabric sleeve 8. The barrel frame 9 is located inside the interface pipe body 52, and the bottom of the barrel frame 9 intersects with the upper end of the feed column 55.

[0045] Among them, the non-woven fabric sleeve 8 is sleeved on the outside of the tube frame 9. Before the external interface is used, the hook and the limiting arc groove 63 can be separated, and the plug cover body 4 can be rotated to provide a cleaning process for the inner wall of the interface.

[0046] When in use, manually remove the hook on the lock seat 62 from the limiting arc groove 63, then push the hook outward, manually rotate the plug cover 4 two circles, so that the non-woven fabric sleeve 8 provides pre-cleaning operation for the inner wall of the interface tube body 52, and insert the pipeline of the external equipment into the interior of the interface tube body 52. ​​The pipeline of the external equipment will push the feed column 55 inside the interface tube body 52 downward. At this time, the feed port 58 opened by the feed column 55 enters the compression chamber, and the vacuum pump can be started normally to transmit the material. If the vacuum pump faces different equipment in the later stage, the external equipment pipeline disassembled from the interface tube body 52 is removed, and the fixing plate 53, the sealing seat 59 and the feed column 55 will be reset by the influence of the spring 57. At this time, the compression chamber outlet is sealed and flushed by the sealing seat 59, and other unused interfaces are also sealed. At this time, when cleaning the compression chamber, the cleaning of the interface pipeline is omitted, and the cleaning is more convenient, which prevents the residue on the inner wall of the unused interface pipeline when conveying materials, resulting in mixed pollution.

[0047] A multi-flow vacuum pump can be used to install a vacuum pump plug. The multi-flow vacuum pump includes a frame 1 and a motor 2 installed on the frame 1. A cylinder 3 is arranged on one side of the motor 2, and the cylinder 3 is connected to the side of the compression chamber.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
