DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the present utility model in conjunction with embodiments.

[0026] Please refer to Figures 1-6, the present utility model provides a vacuum pump for methyltetrahydrophthalic anhydride, including a vacuum pump body 1. The vacuum pump body 1 further includes two support frames 2, and the two support frames 2 are symmetrically distributed and fixed on one side wall of the vacuum pump body 1. A bottom plate 3 is arranged directly below the vacuum pump body 1. Two symmetrically distributed mounting grooves 4 are opened on one side wall of the bottom plate 3. A bearing plate 5 is fixed inside the mounting groove 4. A buffer assembly 6 adapted to the vacuum pump body 1 is arranged on one side of the bottom plate 3.

[0027] Further, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, it is worth specifically explaining that the buffer assembly 6 includes two mounting plates 61. The two mounting plates 61 are slidably connected to one side wall of the two support frames 2. A mounting plate 62 is fixed to the bottom side wall of the mounting plate 61. Two symmetrically distributed hinge seats a63 are fixed to the bottom side wall of the mounting plate 62. A plurality of symmetrically distributed sliding grooves 64 are opened on the top side wall of the bottom plate 3. A sliding block 65 is slidably connected inside the sliding groove 64. A hinge seat b66 is fixed to the top side wall of the sliding block 65. A connecting rod 67 is hinged between the hinge seat b66 and the hinge seat a63. A damper a68 is fixed to one side wall of the sliding block 65. The end of the damper a68 away from the sliding block 65 is fixed inside the sliding groove 64. A spring a69 is sleeved on the outer surface of the damper a68. One end of the spring a69 is fixed to one side wall of the sliding block 65, and the other end of the spring a69 is fixed to one side of the sliding groove 64; two connecting plates 610, the two connecting plates 610 are fixed to one side wall of the two mounting plates 61. A plurality of symmetrically distributed dampers b611 are fixed to the top side wall of the bottom plate 3. The end of the damper b611 away from the bottom plate 3 is fixed with a connecting ring 612. A spring b613 is sleeved on the outer surface of the damper b611. One end of the spring b613 is fixed to one side wall of the connecting ring 612, and the other end of the spring b613 is fixed to the top side wall of the bottom plate 3. Through the setting of the buffer assembly 6, the vibration amplitude generated by the vacuum pump body 1 during operation can be reduced to a greater extent, ensuring that the vacuum pump body 1 works under a relatively stable state. It can not only improve the safety performance of the vacuum pump body 1, but also greatly improve the product working quality of the vacuum pump body 1, and has strong practicability.

[0028] Further, as Figure 1 , Figure 2 and Figure 5As shown in the figure, it is worth specifically stating that the vertical section of the mounting plate 61 is set in an F shape. Two symmetrically distributed mounting hole grooves 7 are opened on one side wall of the support frame 2. One side of the mounting plate 61 is fixed to the support frame 2 by two symmetrically distributed bolts 8. Through the setting of the bolts 8, the connection stability between the mounting plate 61 and the support frame 2 can be effectively ensured, making the connection between the mounting plate 61 and the support frame 2 more reliable and compact. And through the shape setting of the mounting plate 61, it is convenient for the staff to disassemble and assemble the vacuum pump body 1, greatly improving the stability of the vacuum pump body 1 during operation.

[0029] This solution has the following working process: When it is necessary to reduce the noise and vibration of the vacuum pump body 1, when the vacuum pump body 1 is in a normal operating state, through the setting of the damper b611 and the spring b613, the vibration generated during the operation of the vacuum pump body 1 is offset, reducing the amplitude generated during the operation of the vacuum pump body 1. And by the action of the connecting rod 67, the sliding block 65 is forced to move along the chute 64. In cooperation with the setting of the damper a68 and the spring a69, the generation of vibration of the vacuum pump body 1 can be reduced. By the setting of the sound insulation frame 9, the noise generated during the operation of the vacuum pump body 1 is greatly reduced. Rotate the runner 13 to make the threaded rod 12 rotate synchronously. By the threaded transmission between the threaded rod 12 and the threaded hole 11, the threaded rod 12 is forced to move spirally downward, thereby driving the shock-absorbing plate 14 to move synchronously until the shock-absorbing plate 14 is in a state of being in contact with the vacuum pump body 1, and the vibration generated by the vacuum pump body 1 can be conducted to the bottom plate 3, reducing the noise generated during the operation of the vacuum pump body 1 through the way of force unloading and conduction.

[0030] According to the above working process, it can be seen that through the setting of the buffer assembly 6, the vibration amplitude generated by the vacuum pump body 1 during operation can be reduced to a greater extent, ensuring that the vacuum pump body 1 works in a relatively stable state. This can not only improve the safety performance of the vacuum pump body 1, but also greatly improve the product working quality of the vacuum pump body 1, with strong practicability. And through the setting of the threaded rod 12, the threaded hole 11 and the shock-absorbing plate 14, the distance between the shock-absorbing plate 14 and the vacuum pump body 1 can be adjusted according to specific needs, so as to ensure that the shock-absorbing plate 14 can be in contact with the vacuum pump body 1. Due to the setting of the shock-absorbing plate 14, the amplitude generated during the operation of the vacuum pump body 1 is reduced, thereby effectively reducing the generation of noise.

[0031] Furthermore, as Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown, it is worth specifically stating that the central axis of the connecting ring 612 is collinear with the central axis of the damper b611, and the included angle between the additional installation plate 62 and the installation plate 61 is set at a right angle. Through the angular position setting between the additional installation plate 62 and the installation plate 61, the connection reliability between the additional installation plate 62 and the installation plate 61 is effectively ensured, and the connection stability of the additional installation plate 62 is effectively improved.

[0032] Further, as shown in Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth specifically stating that a sound insulation frame 9 is fixed on the side wall of the top end of the bottom plate 3. The vacuum pump body 1 is located inside the sound insulation frame 9. Two sound absorption plates 10 are symmetrically distributed and fixed on the outer side wall of the sound insulation frame 9. Through the setting of the sound absorption plates 10, the noise generated around during the operation of the vacuum pump body 1 can be absorbed, thereby ensuring that the noise pollution generated when the vacuum pump body 1 works is smaller.

[0033] Further, as shown in Figure 2 and Figure 4 As shown, it is worth specifically stating that a threaded hole 11 is opened on one side wall of the sound insulation frame 9. A threaded rod 12 is threadedly connected to the threaded hole 11. One end of the threaded rod 12 is fixed with a rotating wheel 13, and the other end of the threaded rod 12 is rotatably connected to a shock absorption plate 14. One side of the shock absorption plate 14 is in contact with one side of the vacuum pump body 1. A plurality of symmetrically distributed guide rods 15 are fixed on the side wall of the top end of the shock absorption plate 14. The guide rods 15 are slidably penetrated through the side wall of the sound insulation frame 9. Through the setting of the threaded rod 12, the threaded hole 11 and the shock absorption plate 14, the distance between the shock absorption plate 14 and the vacuum pump body 1 can be adjusted according to specific requirements, so as to ensure that the shock absorption plate 14 can be in a fitting state with the vacuum pump body 1. Due to the setting of the shock absorption plate 14, the amplitude generated during the operation of the vacuum pump body 1 is reduced, thereby effectively reducing the generation of noise.

[0034] In summary: Through the setting of the bolt 8, the connection stability between the installation plate 61 and the support frame 2 can be effectively ensured, making the connection between the installation plate 61 and the support frame 2 more reliable and compact. And through the shape setting of the installation plate 61, it is convenient for the staff to disassemble and assemble the vacuum pump body 1, greatly improving the stability during the operation of the vacuum pump body 1. And through the angular position setting between the additional installation plate 62 and the installation plate 61, the connection reliability between the additional installation plate 62 and the installation plate 61 is effectively ensured, and the connection stability of the additional installation plate 62 is effectively improved. And through the setting of the sound absorption plates 10, the noise generated around during the operation of the vacuum pump body 1 can be absorbed, thereby ensuring that the noise pollution generated when the vacuum pump body 1 works is smaller.

[0035] The vacuum pump body 1 can be purchased on the market. The vacuum pump body 1 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
