Description

Technical Field

[0001] This utility model relates to the field of vertical vacuum pump technology, specifically a vertical vacuum pump that improves production efficiency. 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. According to installation requirements, it is mainly divided into two types: vertical vacuum pumps and horizontal vacuum pumps.

[0003] An investigation revealed that a utility model patent discloses a vertical vacuum pump for improving production efficiency (publication number: CN212429130U), comprising a pump body, a motor, and a mounting bracket. The motor is bolted to the top of the pump body. An inlet pipe and an outlet pipe are located on opposite sides of the pump body. A pressure booster cylinder is welded to the top of the outlet pipe, and a hydraulic cylinder is bolted to the top of the pressure booster cylinder. A sealing rubber block is bonded to one end of the hydraulic cylinder and is secured inside the pressure booster cylinder. An inlet groove and an outlet groove are provided between the pressure booster cylinder and the inner wall of the outlet pipe. A guide valve block one and a guide valve block two are fused into the inlet groove and the outlet groove, respectively. A wiring plug and a switch assembly are provided on the outlet pipe. The wiring plug is connected to the switch assembly via wires, and the switch assembly is connected to the motor and the hydraulic cylinder via wires. Both guide valve block one and guide valve block two have internal cavities, with inlet holes and outlet holes on opposite sides of the inner wall of each cavity. This pump is characterized by high efficiency and flexible operation.

[0004] Although the aforementioned patent provides a vacuum pump with high efficiency and flexible use by setting inlet and outlet holes on both sides of the inner wall of the cavity, during installation and use, although it adopts a lifting adjustment, the pump body usually cannot be adjusted in angle after installation. Consequently, when the outlet pipe of the device faces the opposite direction to the connected equipment, the end of the installation hose will bend during installation, resulting in the breakage of the hose bend and reducing the service life of the pipe. This reduces the flexibility and stability of the device in actual use.

[0005] Therefore, this utility model provides a vertical vacuum pump to improve production efficiency and solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4As shown, this utility model provides a vertical vacuum pump for improving production efficiency, including a vacuum pump body 1, a discharge pipe 11 on one side of the bottom of the vacuum pump body 1, a feed pipe 12 on the other side of the bottom of the vacuum pump body 1, and a positioning flange 13 integrally formed at the bottom of the vacuum pump body 1; a lifting assembly 2, which is located below the vacuum pump body 1, and a support assembly 3 is fixedly connected to the top end of the lifting assembly 2. The support assembly 3 is used for mounting and fixing the vacuum pump body 1. The support assembly 3 includes a support ring 31, with a ball bearing 32 rotatably connected inside the support ring 31, and a retaining ring 33 symmetrically fixedly connected to the upper surface of the support ring 31. The positioning flange 13 is wrapped between the support ring 31 and the retaining ring 33. Through the rotation of the ball bearing 32, when the ball bearing 32 contacts the positioning flange 13, the rotation structure of the ball bearing 32 can realize the lifting of the vacuum pump body 1. The circumferential rotation adjustment allows for adaptive adjustment of the orientation of the discharge pipe 11 and the feed pipe 12, improving the convenience of subsequent pipe installation. It eliminates the need to bend the metal pipes and prevents excessive wear caused by bending the hoses during installation.

[0020] Furthermore, the outer diameter of the positioning flange 13 is equal to the maximum inner diameter of the retaining ring 33. The cross-section of the retaining ring 33 is L-shaped, and the minimum inner diameter part of the retaining ring 33 covers the upper surface of the positioning flange 13. There are two retaining rings 33, and the two retaining rings 33 are symmetrically distributed. Positioning holes 34 are opened at both the support ring 31 and the retaining ring 33, and high-strength bolts are inserted and tightened inside the positioning holes 34. By the retaining ring 33 engaging and wrapping the positioning flange 13, the upper and lower limits and the horizontal limit of the positioning flange 13 are completed, so that the positioning flange 13 can only rotate horizontally.

[0021] Furthermore, the horizontal end of the retaining ring 33 has a threaded hole 35, and a hand-tightening bolt is connected to the internal thread of the threaded hole 35. The bottom of the hand-tightening bolt abuts against the upper surface of the positioning flange 13, the lower surface of the positioning flange 13 abuts against the upper surface of the ball 32, and the top tangent of the ball 32 is above the upper surface of the support ring 31. Through the installation and cooperation of the hand-tightening bolt, the positioning flange 13 is assisted in positioning by pressing it. By increasing the pressing force on the positioning flange 13, the friction of the horizontal rotation of the positioning flange 13 is increased, thereby completing the angular positioning of the positioning flange 13 and improving the stability of the device.

[0022] Furthermore, the lifting assembly 2 includes a support frame 21, with a threaded rod 22 threadedly connected to the center of the support frame 21. A lifting frame 23 is rotatably connected to the top of the threaded rod 22. The lifting frame 23 is the lifting end of the lifting assembly 2 and is fixedly connected to the bottom of the support ring 31. A positioning sleeve 24 is fixedly connected to the upper surface of the support frame 21, and a positioning shaft 25 is slidably inserted into the inside of the positioning sleeve 24. The top of the positioning shaft 25 is fixedly connected to the lower surface of the support ring 31. The positioning sleeve 24 and the positioning shaft 25 are evenly distributed circumferentially between the support frame 21 and the support ring 31. The top of the threaded rod 22 has an I-shaped structure, and an anti-slip handle is fixedly connected to the bottom of the threaded rod 22. By rotating the threaded rod 22, the support ring 31 can be adjusted up and down under the connection of the lifting frame 23, thereby adapting the height of the vacuum pump body 1 and facilitating auxiliary docking for pipeline installation.

[0023] Working principle: During the installation of the vacuum pump body 1, the positioning flange 13 is placed above the ball bearing 32, and then the retaining ring 33 is engaged above the support ring 31. The retaining ring 33 engages with the positioning flange 13 simultaneously, thus coaxially pressing and positioning it. After the retaining ring 33 is installed and fixed with the support ring 31, it achieves auxiliary positioning of the positioning flange 13. At this time, the positioning flange 13 can only rotate horizontally to adjust the orientation of the discharge pipe 11 and the feed pipe 12. Finally, after adjusting the working height of the vacuum pump body 1 by driving the lifting component 2, the hand-tightening bolt on the retaining ring 33 is rotated, so that the hand-tightening bolt presses and positions the positioning flange 13, ensuring the secure installation of the vacuum pump body 1 and improving the stability of the vacuum pump body 1 in use.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
