Description

Technical Field

[0001] This utility model relates to the technical field of vacuum pumps, specifically to a horizontal dual-motor driven integrated positive air pump main unit. Background Technology

[0002] The horizontal dual-motor driven integrated positive air pump is an advanced vacuum device, its technological background stemming from the demand for efficient and stable vacuum systems. Traditional vacuum pumps mostly employ single-motor drives, resulting in low efficiency and uneven load distribution. With industrial development, dual-motor drive technology emerged, improving system efficiency and reliability through the coordinated operation of two horizontally arranged motors. The integrated design further simplifies the structure, reduces space occupation, and facilitates maintenance. This technology is widely used in semiconductor, medical, and food processing industries, meeting the requirements for high vacuum and high stability, and driving progress in these industries.

[0003] Application number CN202120346401.8 discloses an independently adjustable dual-motor, dual-main-unit, two-stage vacuum pump system. This vacuum pump system includes a main frame composed of horizontal beams and columns. Two main pump units and two adjustable support plates are respectively mounted on the main frame. Two motors driving the main pump units are respectively mounted on the adjustable support plates. The outlet end of the first main pump unit and the inlet end of the second main pump unit are connected by a connecting pipe. This utility model's installation and adjustment structure has the following advantages: It uses two independent motors to drive the main pump units, and the positions of the two motors can be independently adjusted and controlled. Only the tilt angle of the support plates needs to be adjusted, making adjustment more convenient and easier to control. The two sets of main pump units and motors are arranged vertically and horizontally in a staggered manner, which minimizes the distance between the outlet end of the first main pump unit and the inlet end of the second main pump unit, resulting in a more compact structure and smaller equipment size. However, it has a drawback: when the exhaust port needs to be connected, it cannot provide convenient installation work, requiring traditional bolt fixing, which is somewhat cumbersome.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4 As shown, this utility model is a horizontal dual-motor driven integrated positive air pump main unit, including an assembly housing assembly 1. An active rotor assembly 2 is installed inside one side of the assembly housing assembly 1, and a convenient connection assembly 4 is installed on the rear side of the assembly housing assembly 1. A passive rotor assembly 3 is installed on one side of the active rotor assembly 2, and the passive rotor assembly 3 is located on the other side inside the assembly housing assembly 1.

[0026] The convenient connection component 4 includes an adjustment slot 401. Limit adjustment slots 402 are provided on both sides of the bottom of the adjustment slot 401. A return spring 403 is installed inside the limit adjustment slot 402. A limit plate 404 is installed on the top of the return spring 403. A limit frame 405 is installed on the top of the limit plate 404. The limit frame 405 can limit the connection of the pipes to be connected. The convenient connection component 4 quickly fixes the external pipe to the adjustment slot 401 through the limit frame 405. The design of the return spring 403 and the limit plate 404 ensures a stable pipe connection and easy disassembly. The tight connection between the limit frame 405 and the pipe ensures the airtightness of the gas during transmission and prevents leakage.

[0027] By installing the convenient connection component 4 on the rear side of the device, when it is necessary to connect the exhaust port of the device, the installation work can be easily carried out by using the convenient connection component 4.

[0028] The assembly housing component 1 includes a mounting housing 101, with limiting holes 102 on both sides of the bottom of the mounting housing 101, and an assembly cover 103 connected to the top of the mounting housing 101 by fixing bolts 104.

[0029] The active rotor assembly 2 includes a transmission wheel 201, a rotating rod 202 mounted in the middle of the transmission wheel 201, the rotating rod 202 being installed inside the roller bearing 203, and an active gear 204 mounted near the bottom of the rotating rod 202. Meanwhile, a male rotor 205 is connected to the bottom of the rotating rod 202. The active rotor assembly 2 is driven by a motor, which drives the transmission wheel 201 to rotate. The transmission wheel transmits power to the active gear 204 and the male rotor 205 through the rotating rod 202. The active gear 204 meshes with the driven gear 301, driving the driven gear 301 to rotate.

[0030] The passive rotor assembly 3 includes a passive gear 301, which is disposed on one side of the driving gear 204 and meshes with the driving gear 204. The passive gear 301 is also mounted on the top of the limiting rod 302, and the bottom of the limiting rod 302 is connected to a female rotor 303. The female rotor 303 meshes with the male rotor 205, and both the female rotor 303 and the male rotor 205 are disposed inside the mounting housing 101. The passive gear drives the female rotor 303 to rotate through the limiting rod 302, and the male rotor 205 and the female rotor 303 mesh with each other to form a pair of rotating sealed cavities. As the rotor rotates, the volume of the cavity changes periodically, thereby realizing the intake and exhaust of gas. When the male rotor 205 and the female rotor 303 rotate, the volume of the cavity gradually increases, forming a negative pressure. External gas is drawn into the cavity through the air inlet. As the rotor continues to rotate, the volume of the cavity gradually decreases, and the gas is compressed. When the volume of the cavity reaches the minimum value, the compressed gas is discharged through the exhaust port 1011.

[0031] An exhaust port 1011 is provided in the middle of the rear side of the mounting housing 101, and an adjustment slot 401 is connected to the outer wall of the exhaust port 1011.

[0032] The top side of the assembly cover 103 is provided with an installation tube groove 1031, and the inner side of the installation tube groove 1031 is provided with a gear installation groove 1033. The inside of the installation tube groove 1031 is limited by a roller positioning ring 1032 to install a rotating rod 202. The inside of the gear installation groove 1033 is limited to install a driving gear 204 and a driven gear 301.

[0033] The active rotor assembly 2 is driven by a motor, which drives the transmission wheel 201 to rotate. The transmission wheel transmits power to the active gear 204 and the male rotor 205 through the rotating rod 202. The active gear 204 meshes with the passive gear 301, driving the passive gear 301 to rotate. The passive gear drives the female rotor 303 to rotate through the limiting rotating rod 302. The male rotor 205 and the female rotor 303 mesh with each other to form a pair of rotating sealed cavities. As the rotor rotates, the volume of the cavity changes periodically, thus achieving gas intake and exhaust. When the male rotor 205 and female rotor 303 rotate, the cavity volume gradually increases, forming a negative pressure, and external gas is drawn into the cavity through the air inlet. As the rotor continues to rotate, the cavity volume gradually decreases, and the gas is compressed. When the cavity volume reaches its minimum value, the compressed gas is discharged through the exhaust port 1011. The convenient connection component 4 quickly fixes the external pipe to the adjustment slot 401 through the limiting frame 405. The design of the return spring 403 and the limiting plate 404 ensures that the pipe connection is stable and easy to disassemble. The tight connection between the limiting frame 405 and the pipe ensures the airtightness of the gas during transmission and prevents leakage. The mounting housing 101 and the assembly cover 103 are tightly connected by the fixing bolts 104 to form a closed space, ensuring the stable operation of the rotor assembly and gear assembly. At the rear of the housing 101, the compressed gas is discharged. The driving gear 204 and the driven gear 301 transmit power through meshing, ensuring that the male rotor 205 and the female rotor 303 rotate synchronously. The roller bearing 203 and the roller positioning ring 1032 support the rotating rod 202 and the limiting rod 302, reduce friction, and ensure the smooth operation of the rotor assembly. During operation, the motor drives the driving rotor assembly 2 to rotate, which in turn drives the driving gear 204 and the male rotor 205. The driving gear 204 drives the driven gear 301 and the female rotor 303 to rotate through meshing. The meshing motion of the male rotor 205 and the female rotor 303 forms a periodically changing cavity, realizing the intake, compression, and discharge of gas. The gas is discharged through the exhaust port 1011, completing the working cycle of the vacuum pump. The convenient connection component 4 ensures the quick connection and sealing of external pipelines, improving the ease of operation of the equipment. This dual-motor driven integrated positive air pump unit achieves gas intake, compression, and discharge through the coordinated operation of the active rotor assembly 2 and the passive rotor assembly 3, utilizing gear meshing and changes in rotor cavity volume. The design of the convenient connection assembly 4 and the assembly housing assembly 1 further improves the equipment's sealing performance, stability, and ease of operation.
