Description

Technical Field

[0001] This utility model relates to a Roots vacuum pump unit, and more particularly to a skid-mounted Roots vacuum pump unit with a multi-stage vacuum extraction structure. Background Technology

[0002] The Roots vacuum pump is a high-efficiency rotary positive displacement vacuum pump. Its working principle is based on the reciprocating motion of two rotors, thereby achieving efficient gas transfer.

[0003] Currently, most Roots vacuum pump units cannot be transported as a whole by skid. During delivery, each component needs to be transported to the site for assembly, such as the motor, silencer, and exhaust pipe, resulting in low assembly efficiency.

[0004] Especially for multi-stage Roots vacuum pump units, which consist of multiple sets of vacuum pumps, on-site assembly is difficult and costly.

[0005] Furthermore, since most Roots vacuum pump units are not equipped with overall protective devices, they are easily contaminated and damaged when operating in harsh environments, reducing the overall service life of the unit. Utility Model Content

[0006] This utility model addresses the above-mentioned technical problems by providing a skid-mounted Roots vacuum pump unit with a multi-stage vacuum extraction structure. This Roots vacuum pump unit can be transported as a whole by skid, resulting in high transportation efficiency. Furthermore, a protective cover is installed on the outside of the unit, providing all-round protection for the internal unit and preventing contamination and damage when the unit operates in harsh environments, thereby further extending the service life of the entire unit.

[0007] Therefore, the technical solution of this utility model is a skid-mounted Roots vacuum pump unit with a multi-stage vacuum extraction structure, which is provided with a base, a skid hole on the base, a protective cover at the upper end of the base, and the protective cover is fixedly connected to the base.

[0008] The protective cover consists of a front protective plate, a rear protective plate, a left protective plate, a right protective plate, and an upper protective plate. Inside the protective cover, at the upper end of the base, there is a fixed support assembly. The fixed support assembly is stepped in shape and is fixedly connected to the base.

[0009] The fixed support assembly includes a first support and a second support. The height of the first support is higher than that of the second support. A first motor and a first Roots vacuum pump are fixedly mounted on the upper end of the first support. The first motor can drive the first Roots vacuum pump to run. A second motor and a second Roots vacuum pump are fixedly mounted on the upper end of the second support. The second motor can drive the second Roots vacuum pump to run.

[0010] The first Roots vacuum pump has an inlet pipe on one side of its inlet, with one end connected to the inlet of the first Roots vacuum pump and the other end extending to the outside of the protective cover. The first Roots vacuum pump has an intermediate connecting pipe on one side of its outlet, with one end connected to the outlet of the first Roots vacuum pump and the other end connected to the inlet of the second Roots vacuum pump. The second Roots vacuum pump has an outlet pipe on one side of its outlet, with one end connected to the outlet of the second Roots vacuum pump and the other end extending to the outside of the protective cover.

[0011] An electrical cabinet is fixedly installed at the upper end of the base, adjacent to the inner side of the front guard plate. The electrical cabinet has ventilation holes. A control panel and an air intake grille are respectively installed on the front guard plate at the corresponding positions of the electrical cabinet.

[0012] An exhaust fan is installed on the left side panel;

[0013] An air intake grille is located on the right side guard plate.

[0014] Preferably, one end of the air intake pipe located outside the protective cover extends upwards to the outside of the upper protective plate;

[0015] One end of the vent pipe, located outside the protective cover, extends backward to the outside of the rear guard plate.

[0016] Preferably, there are multiple air intake grilles on the right guard plate, and the multiple air intake grilles are located at the corresponding positions of the first motor and the second motor.

[0017] Preferably, the electrical cabinet is equipped with an exhaust fan.

[0018] Preferably, a flange is fixedly provided at one end of the air inlet pipe and the air outlet pipe located outside the protective cover.

[0019] Preferably, the front guard plate, rear guard plate, left guard plate, right guard plate, and upper guard plate are all detachable and fixed.

[0020] Preferably, the first motor and the first Roots vacuum pump, as well as the second motor and the second Roots vacuum pump, are connected by couplings, and a coupling cover is fixedly provided on the outside of the coupling.

[0021] The beneficial effects of this utility model are:

[0022] 1. The protective cover and the base form a complete skid-mounted enclosure. This enclosure has the functions of overall skid mounting, sound insulation and noise reduction, as well as protection against dust, water, and impact. Furthermore, since the base is provided with skid mounting holes, the entire unit can be skid-mounted and transported by inserting the support arm of a forklift into the skid mounting holes during transportation. This operation is convenient and quick.

[0023] 2. An electrical cabinet is fixedly installed at the upper end of the base, adjacent to the inner side of the front guard plate. The electrical cabinet is used to store electrical components such as power cords and signal lines, and to isolate and protect the electrical components, preventing them from being exposed inside the protective cover and causing operational interference. In addition, it can avoid the risk of electric shock during maintenance.

[0024] 3. Since the front guard plate is equipped with an air intake grille at the corresponding position of the electrical cabinet, the left guard plate is equipped with an exhaust fan, and the right guard plate is equipped with an air intake grille, external air can enter the electrical cabinet and the interior of the protective cover through the air intake grilles on the front guard plate and the right guard plate respectively. The air entering the electrical cabinet enters the interior of the protective cover through the vents on the electrical cabinet, and is finally discharged outward through the exhaust fan. The air entering the protective cover will also be discharged outward through the exhaust fan, thus forming a continuous airflow, which can continuously reduce the temperature inside the protective cover and the electrical cabinet, ensuring the long-term stable operation of the vacuum pump;

[0025] Furthermore, since the air intake grilles are located on the front and right guard plates respectively, and the exhaust fan is located on the left guard plate, the airflow covers the entire area inside the guard, enabling comprehensive heat dissipation and cooling of the relevant components inside the guard.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] pass Figures 1-5 As can be seen, the skid-mounted Roots vacuum pump unit with multi-stage vacuum extraction structure is equipped with a base 2, and the base 2 is provided with skid mounting holes 201. During transportation, the support arm of the forklift can be inserted into the skid mounting holes 201 to realize the overall skid-mounted transportation of the unit.

[0035] The upper end of the base 2 is provided with a protective cover 1, which is fixedly connected to the base 2 to form a complete skid-mounted box. The box has the functions of overall skid mounting, sound insulation and noise reduction, as well as dustproof, waterproof and impact-proof protection.

[0036] The protective cover 1 consists of a front protective plate 101, a rear protective plate 102, a left protective plate 103, a right protective plate 104, and an upper protective plate 105. Inside the protective cover 1, at the upper end of the base 2, there is a fixed support assembly 14. The fixed support assembly 14 is stepped and is fixedly connected to the base 2. The main function of the stepped fixed support assembly 14 is to facilitate the high and low position assembly of the first Roots vacuum pump 11 and the second Roots vacuum pump 13.

[0037] The fixed support assembly 14 includes a first support 1401 and a second support 1402. The height of the first support 1401 is higher than that of the second support 1402. A first motor 10 and a first Roots vacuum pump 11 are fixedly mounted on the upper end of the first support 1401. The first motor 10 can drive the first Roots vacuum pump 11 to run. A second motor 12 and a second Roots vacuum pump 13 are fixedly mounted on the upper end of the second support 1402. The second motor 12 can drive the second Roots vacuum pump 13 to run.

[0038] An inlet pipe 6 is provided on one side of the inlet of the first Roots vacuum pump 11. One end of the inlet pipe 6 is connected to the inlet of the first Roots vacuum pump 11, and the other end of the inlet pipe 6 extends to the outside of the protective cover 1. An intermediate connecting pipe 15 is provided on one side of the outlet of the first Roots vacuum pump 11. One end of the intermediate connecting pipe 15 is connected to the outlet of the first Roots vacuum pump 11, and the other end of the intermediate connecting pipe 15 is connected to the inlet of the second Roots vacuum pump 13. An outlet pipe 7 is provided on one side of the outlet of the second Roots vacuum pump 13. One end of the outlet pipe 7 is connected to the outlet of the second Roots vacuum pump 13, and the other end of the outlet pipe 7 extends to the outside of the protective cover 1. Finally, the first Roots vacuum pump 11 and the second Roots vacuum pump 13 are assembled in series to complete the multi-stage vacuum extraction structure and increase the gas compression efficiency.

[0039] An electrical cabinet 9 is fixedly installed at the upper end of the base 2, adjacent to the inner side of the front guard plate 101. The electrical cabinet 9 is used to store electrical components such as power cords and signal lines, and to isolate and protect the electrical components, preventing them from being exposed inside the protective cover 1 and causing operational interference. In addition, it can avoid the risk of electric shock during maintenance.

[0040] The electrical cabinet 9 is equipped with a vent 901, which can circulate and cool the inside of the electrical cabinet 9 to prevent the internal temperature of the electrical cabinet 9 from being too high and causing damage to the electrical components.

[0041] A control panel 3 is provided on the front panel 101 at the corresponding position of the electrical cabinet 9. The control panel 3 is equipped with start, stop, emergency stop buttons, etc., which can control the start and stop of the first motor 10 and the second motor 12, as well as the emergency stop.

[0042] Depending on actual usage requirements, temperature sensors, humidity sensors, and other monitoring devices can also be installed inside the protective cover 1, and relevant parameters can be displayed in real time through the control panel 3 to achieve real-time monitoring.

[0043] An air intake grille 5 is provided on the front guard plate 101 at the corresponding position of the electrical cabinet 9, an exhaust fan 4 is provided on the left guard plate 103, and an air intake grille 5 is provided on the right guard plate 104.

[0044] External air can enter the electrical cabinet 9 and the protective cover 1 through the air intake grilles 5 on the front guard plate 101 and the right guard plate 104 respectively. The air entering the electrical cabinet 9 enters the protective cover 1 through the vent 901 on the electrical cabinet 9, and is finally discharged to the outside through the exhaust fan 4. The air entering the protective cover 1 is also discharged to the outside through the exhaust fan 4, thus forming a continuous airflow, which can continuously reduce the temperature inside the protective cover 1 and ensure the long-term stable operation of the vacuum pump.

[0045] To increase the practicality of the unit assembly, the following embodiment is adopted:

[0046] One end of the air intake pipe 6 located outside the protective cover 1 extends upward to the outside of the upper protective plate 105, and one end of the air outlet pipe 7 located outside the protective cover 1 extends backward to the outside of the rear protective plate 102.

[0047] In this embodiment, since most vacuum pump units operate with top inlet and side outlet in actual use, the inlet pipe 6 is passed upward and the outlet pipe 7 is passed to the side to meet the usage requirements of most vacuum pump units.

[0048] To increase the heat dissipation efficiency inside the protective cover 1, the following embodiment is adopted:

[0049] There are multiple air intake grilles 5 on the right guard plate 104, and the multiple air intake grilles 5 are located at the corresponding positions of the first motor 10 and the second motor 12.

[0050] In this embodiment, since the heat generated by the motor is particularly prominent during long-term operation of the unit, the air intake grille 5 is set at the corresponding position of the first motor 10 and the second motor 12 to minimize the temperature of the motor and ensure the long-term stable operation of the unit as a whole.

[0051] Furthermore, combined Figure 1 , Figure 2 It can be seen that the air intake grille 5 is respectively installed on the front guard plate 101 and the right guard plate 104, and the exhaust fan 4 is installed on the left guard plate 103. When the air flows, it covers the entire area inside the protective cover 1, which can dissipate heat and cool down the relevant components inside the protective cover 1 in all directions.

[0052] To further increase airflow inside electrical cabinet 9, the following embodiment is adopted:

[0053] The electrical cabinet 9 is equipped with an exhaust fan 4. Some of the air entering the electrical cabinet 9 enters the protective cover 1 through the vent 901, and some enters the protective cover 1 through the exhaust fan 4.

[0054] In this embodiment, the exhaust fan 4 plays the role of active exhaust, which can increase the air flow speed inside the electrical cabinet 9, thereby increasing the cooling effect inside the electrical cabinet 9 and further protecting the electrical components inside the electrical cabinet 9.

[0055] Flanges 8 are fixedly installed at one end of the air inlet pipe 6 and the air outlet pipe 7 on the outside of the protective cover 1. The flanges 8 enable quick disassembly and assembly, improving assembly efficiency.

[0056] To facilitate the assembly and disassembly of the protective cover 1, the following embodiment is adopted:

[0057] The front guard plate 101, rear guard plate 102, left guard plate 103, right guard plate 104, and upper guard plate 105 are all detachable and fixed. When it is necessary to inspect the internal components of the protective cover 1, it is only necessary to remove the guard plate at the corresponding position. The operation is simple and quick, saving working time and improving work efficiency.

[0058] The first motor 10 and the first Roots vacuum pump 11, as well as the second motor 12 and the second Roots vacuum pump 13, are connected by couplings. A coupling cover 16 is fixedly provided on the outside of the coupling. By providing the coupling cover 16, the coupling can be protected and prevented from being bumped.

[0059] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
