Description

Technical Field

[0001] This utility model relates to the field of vacuum pump technology, and in particular to a stable vacuum pump. Background Technology

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container to obtain a vacuum. In layman's terms, a vacuum pump is a device that uses various methods to improve, generate, and maintain a vacuum in a closed space. When a vacuum pump is in use, its operational stability is affected by the stability of the pump body support and the impact of impurities in the negative pressure gas on the operation of the pump body. This requires ensuring the stability of the pump body support while also filtering the negative pressure gas entering the pump body to ensure the operational stability of the vacuum pump. Therefore, a stable vacuum pump is needed. Utility Model Content

It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] Please see Figures 1 to 4 This utility model provides a stable vacuum pump, including a negative pressure chamber 2 and a filter chamber 3 arranged in a housing 1. A negative pressure fan 4 is arranged in the negative pressure chamber 2. A connecting hose 5 is arranged between the air inlet end of the negative pressure fan 4 and the filter chamber 3. A V-shaped foot 6 is arranged at the bottom of the negative pressure fan 4. A foot positioning hole 7 is arranged through the V-shaped foot 6. A fan base 9 is arranged at the bottom of the negative pressure chamber 2. A foot positioning plate 8 is arranged on the fan base 9. A base positioning hole 10 matching the foot positioning hole 7 is arranged on the foot positioning plate 8. The foot positioning hole 7 and the base positioning hole 10 are connected by bolts. By setting up the filter chamber 3, the gas entering the negative pressure chamber 2 can be filtered first, thereby avoiding impurities in the gas from damaging the negative pressure chamber 2.

[0034] A connecting hose 5 is installed between the air inlet of the negative pressure fan 4 and the filter chamber 3 to ensure the connection stability between the air inlet of the negative pressure fan 4 and the filter chamber 3. By setting a V-shaped foot 6, the support stability of the negative pressure fan 4 can be improved and the weight of the equipment can be reduced. The foot positioning hole 7 on the V-shaped foot 6 can be used in conjunction with the base positioning hole 10 to fix the V-shaped foot 6 to the foot positioning plate 8, ensuring the support stability of the foot positioning plate 8 for the negative pressure fan 4.

[0035] The foot positioning plate 8 is a right-angled positioning plate. The base positioning hole 10 is located on the foot positioning plate 8 on the vertical side. A foot pad 11 is provided between the bottom of the foot positioning plate 8 and the fan base 9. A positioning bolt is provided on the foot pad 11. A foot pad positioning hole 12 is provided on the bottom edge of the foot positioning plate 8. The positioning bolt passes through the foot pad positioning hole 12.

[0036] By placing the base positioning hole 10 on the foot positioning plate 8 on the vertical side, the connection between the foot positioning hole 7 and the base positioning hole 10 can be facilitated. By setting a foot pad 11 between the bottom of the foot positioning plate 8 and the fan base 9, the positioning bolt can pass through the foot pad positioning hole 12, thereby improving the support stability of the fan base 9 for the negative pressure fan 4.

[0037] Two sets of V-shaped feet 6 are arranged along the length of the negative pressure fan 4, with the openings of the V-shaped feet 6 facing downwards. Multiple sets of foot positioning holes 7 are arranged on the V-shaped feet 6. By arranging the openings of the V-shaped feet 6 downwards, the support stability of the V-shaped feet 6 for the negative pressure fan 4 can be improved. By arranging multiple sets of foot positioning holes 7 on the V-shaped feet 6, the installation position of the foot positioning holes 7 can be adjusted or the number of positioning holes can be increased according to actual use needs, thereby improving the support stability of the V-shaped feet 6 for the negative pressure fan 4.

The outer wall of the filter element 13 is spaced apart from the inner wall of the filter chamber 3. A negative pressure air inlet 14 is provided at the top of the filter chamber 3. By arranging the central axis of the filter element 13 in a horizontal direction, it is convenient to disassemble and replace the filter element 13. On the other hand, the outer contour of the filter element 13 can guide the airflow entering the filter chamber 3. The spaced arrangement between the outer wall of the filter element 13 and the inner wall of the filter chamber 3 improves the filtration efficiency of the filter element 13 and ensures the air intake of the negative pressure fan 4.

[0039] The side end face of filter element 13 away from negative pressure chamber 2 is a sealed end face. By making the side end face of filter element 13 away from negative pressure chamber 2 a sealed end face, the filtration effect of filter element 13 can be guaranteed.

[0040] The filter chamber 3 is equipped with a negative pressure port 15, and the connecting hose 5 is connected to the negative pressure port 15. The negative pressure port 15 is located inside the filter element 13. By placing the negative pressure port 15 inside the filter element 13, it can be ensured that the gas entering the negative pressure fan 4 is gas filtered by the filter element 13, thus ensuring the cleanliness of the gas.

[0041] A filter chamber door 16 is provided on the side of the filter chamber 3 away from the negative pressure chamber 2. The filter chamber door 16 facilitates the replacement and maintenance of the filter element 13.

[0042] A negative pressure chamber door 17 is provided on the side of the negative pressure chamber 2 away from the filter chamber 3. The negative pressure chamber door 17 can ensure the air circulation in the negative pressure chamber 2 and provide a stable working environment for the negative pressure fan 4.

[0043] This invention utilizes a filter chamber to pre-filter the gas entering the negative pressure chamber, thereby preventing impurities in the gas from damaging the negative pressure chamber. A connecting hose is installed between the air inlet of the negative pressure fan and the filter chamber to ensure the connection stability between the air inlet of the negative pressure fan and the filter chamber. By setting V-shaped feet, the support stability of the negative pressure fan can be improved, and the weight of the equipment can be reduced. The foot positioning holes on the V-shaped feet, in conjunction with the positioning holes on the base, can fix the V-shaped feet to the foot positioning plate, ensuring the support stability of the foot positioning plate for the negative pressure fan.
