Description

Technical Field

[0001] The utility model relates to the technical field of blower equipment, and particularly relates to a Roots blower with low noise and simple installation. Background Art

[0002] The Roots blower, also known as a Roots fan, belongs to a positive displacement rotary blower. It is a rotary compressor that compresses and transports gas by the relative movement of two or three lobe-shaped rotors in a cylinder. This type of blower has a simple structure and is easy to manufacture. It is suitable for gas transportation and pressurization in low-pressure applications and can also be used as a vacuum pump. The medium transported by the Roots blower is clean air, clean gas, sulfur dioxide, and other inert gases. It is the preferred product for special gas industries (such as gas, natural gas, biogas, carbon dioxide, sulfur dioxide, etc.) and high-pressure working conditions. The immersed blower is an upgraded version of the Roots blower. The submersible Roots blower, also known as an underwater blower, a bottom blower, and a submersible blower, is mainly used in industries such as municipal river treatment, black and odorous river treatment, integrated sewage treatment, and rural sewage treatment. The immersed Roots blower is generally easy to install.

[0003] For example, Chinese Patent Publication No. CN112524025A discloses a low-noise and easily installed immersed Roots blower, which relates to the technical field of blower equipment. It includes a support base, a servo motor, a Roots blower main unit, an air inlet pipe, an air inlet muffler, an air outlet pipe, and an air outlet muffler. In the present invention, multiple through holes cooperate with each other to effectively guide the air inlet path. Multiple third flexible spherical shells are sleeved inside the first flexible spherical shell and the second flexible spherical shell for multiple buffering treatments. Multiple fourth flexible spherical shells are sleeved inside the third flexible spherical shell for blocking and noise reduction treatments, which can effectively perform flexible noise reduction treatments on the inner and outer sides of the support pipe and at the same time effectively prevent noise from spreading outward. It can effectively reduce the noise generated when the air inlet pipe and the air inlet muffler come into contact with the water surface, ensuring the normal life of the residents around the water area. It can enhance the noise reduction effect and can effectively clamp the support pipe, ensuring the stability of the flexible noise reduction sleeve without the need to additionally set other clamping devices.

[0004] The following problems exist in the prior art:

[0005] Both the existing Roots blower itself and the driver will generate noise. In the prior art, most of the noise reduction measures are aimed at the Roots blower itself, resulting in reduced effects. At the same time, too high a delivery air pressure of the Roots blower will also reduce the service life of the Roots blower itself. The external interfaces lack vibration isolation, noise reduction, and displacement compensation, preventing leakage at the interfaces. Content of the Utility Model

[0028] As Figure 2 - Figure 4 shown, the placing component 1 includes a mounting box 11. A placing base 12 is fixedly connected to the bottom of the mounting box 11. A first mounting hole 13 is opened on the right side of the placing base 12. An inner wall of the first mounting hole 13 is fixedly connected to an outer surface on the right side of the Roots blower component 3. The bottom of the inner cavity of the mounting box 11 is fixedly connected to the bottom of the mounting base 5. A second mounting hole 14 is opened at the top of the inner cavity of the mounting box 11. An inner wall of the second mounting hole 14 is fixedly connected to an outer edge surface at the bottom of the Roots blower component 3. A third mounting hole 15 is opened at the bottom of the inner cavity of the mounting box 11. An inner wall of the third mounting hole 15 is fixedly connected to an outer surface at the bottom of the Roots blower component 3. A sound-absorbing cotton 16 is fixedly connected to an inner wall of the mounting box 11. A vacuum chamber 17 is fixedly connected to the inner wall of the mounting box 11, and the vacuum chamber 17 is located at the outer periphery of the sound-absorbing cotton 16.

[0029] The placing base 12 assists in placing the mounting box 11, and then the first mounting hole 13, the second mounting hole 14 and the third mounting hole 15 assist in stably installing the Roots blower component 3. Then, the sound-absorbing cotton 16 and the vacuum chamber 17 on the inner wall of the mounting box 11 are used to improve the sound insulation and noise reduction in all directions.

[0030] As Figure 5 , Figure 6As shown in the figure, the Roots blower assembly 3 includes a Roots blower main body 31. The axis of the output shaft of the Roots blower main body 31 is fixedly connected to the output end of the drive motor 4. The outer surface of the inlet end of the Roots blower main body 31 is fixedly connected to the inner wall of the second mounting hole 14. An inlet muffler 32 is movably connected to the inlet end of the Roots blower main body 31. The outer surface of the outlet end of the Roots blower main body 31 is fixedly connected to the inner walls of the third mounting hole 15 and the first mounting hole 13. A pressure relief valve 33 is fixedly connected to the outer surface of the outlet end of the Roots blower main body 31 near the top on the right side.

A nickel foam 23 is fixedly connected to the opposite surfaces of the two mounting plates 21, and the nickel foam 23 is located at the front and rear positions of the inner cavity of the mounting box 11.

[0031] By the rotation of the Roots blower main body 31, the inlet muffler 32 connected to the inlet of the Roots blower main body 31 plays a role in inlet sound insulation. With the pressure relief valve 33 and the shock-resistant pressure gauge 34 on the surface of the outlet end of the Roots blower main body 31, the outlet air pressure can be better detected. Excessive air pressure is not conducive to the use of the Roots blower main body 31, and the pressure relief valve 33 can be used to reduce the pressure, which improves the service life of the Roots blower main body 31.

Then, with the pressure relief valve 33 and the shock-resistant pressure gauge 34 on the surface of the outlet end of the Roots blower main body 31, the outlet air pressure can be better detected. If the air pressure is too high, it is not conducive to the use of the Roots blower main body 31. The pressure relief valve 33 can be used to reduce the pressure, thereby improving the service life of the Roots blower main body 31. Then, the combination of the elastic joint 35 and the outlet muffler 36 at the outlet end of the Roots blower main body 31 plays a role in pipeline vibration isolation and noise reduction, and compensating for displacement. The outlet muffler 36 plays a role in reducing the outlet noise; at the same time, the installation box 11 is used to assist in the installation of the driving motor 4, the installation base 5 and the Roots blower assembly 3, improving its peripheral isolation. The sound-absorbing cotton 16 and the vacuum chamber 17 on the inner wall of the installation box 11, as well as the nickel foam 23 on one side of the installation plate 21, play a role in sound insulation and noise reduction for the Roots blower main body 31 and the driving motor 4.
