Description

Technical Field

[0001] This utility model relates to the field of dry claw vacuum technology, and in particular to a dry claw vacuum system with good noise reduction effect. Background Technology

[0002] Dry claw vacuum systems are widely used in many fields such as chemical, pharmaceutical, and electronics due to their advantages such as no oil pollution, high pumping speed, and adaptability to harsh working conditions.

[0003] However, existing dry claw vacuum systems suffer from significant noise problems during operation. The main reasons include: high-frequency noise generated by the friction between the claw rotor and the gas in the cavity during high-speed rotation; mechanical vibration and noise generated by the motor during operation; and the lack of noise reduction structures at the inlet and outlet, further exacerbating noise pollution. This noise not only harms the health of operators but may also affect the surrounding environment, limiting the application of dry claw vacuum systems in situations with high noise requirements. Therefore, a dry claw vacuum system with good noise reduction capabilities is needed. Utility Model Content

[0004] The purpose of this invention is to provide a dry claw vacuum system with good noise reduction, which solves the problem of high noise in the use of existing dry claw vacuum systems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dry claw vacuum system with good noise reduction effect, including a vacuum chamber, a support plate provided on the outer wall of the vacuum chamber, a drive assembly that rotates at high speed inside the vacuum chamber provided above the support plate, an air intake device provided above the vacuum chamber, an air outlet device provided above the vacuum chamber, and the air outlet device being connected to the chassis through a shock-absorbing elastic element.

[0006] Preferably, the drive assembly includes a rotary motor and a claw rotor, with the output shaft of the rotary motor fitted with the claw rotor.

[0007] Preferably, the air intake device and the air exhaust device have a gradually expanding and contracting structure.

[0008] Preferably, the inner wall structure of the vacuum cavity is wavy.

[0009] Preferably, the elastic element is provided with rubber components at its upper and lower ends.

[0010] Preferably, the rubber assembly includes an upper damping pad and a lower damping pad, which are distributed on the upper and lower end faces of the elastic element.

[0011] Preferably, the vacuum cavity adopts a multi-layer composite structure, consisting of a sound-absorbing layer, a sound-insulating layer, and a protective layer from the inside out.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] A claw rotor driven by a rotary motor rotates at high speed inside the vacuum chamber, drawing in gas from the intake device and expelling it from the exhaust device. The vibration generated during the operation of the drive components can be further reduced by the cooperation of elastic elements and rubber components. At the same time, the wave-shaped structure on the inner wall of the vacuum chamber can disrupt the flow path of the gas in the vacuum chamber and reduce the regular reflection between the gas and the chamber wall.

[0022] 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.

[0023] This utility model relates to a dry claw vacuum system with good noise reduction effect, such as Figure 1-7 As shown, the system includes a vacuum chamber 1, which employs a multi-layer composite structure. The sound-absorbing layer is made of polyester fiber sound-absorbing cotton, effectively absorbing noise generated within the system. The sound-insulating layer is made of steel plate, blocking noise transmission outwards. The protective layer is made of fire-retardant plastic sheeting, protecting the internal structure and extending the service life of the soundproof enclosure. From the inside out, the layers are the sound-absorbing layer, the sound-insulating layer, and the protective layer. A support plate 2 is fixedly connected to the outer wall of the vacuum chamber 1. A drive assembly 3, extending into the vacuum chamber 1, is fixedly connected to the top surface of the support plate 2. The support plate 2 supports the drive assembly 3. The drive assembly 3 runs through the interior of the vacuum chamber 1 and rotates at high speed. The top surface of the vacuum chamber 1 is fixedly connected to the suction device 4, and the gas enters through the suction device 4. The bottom surface of the vacuum chamber 1 is fixedly connected to the exhaust device 5, which plays the role of exhausting gas. The bottom surface of the exhaust device 5 is fixedly connected to the top surface of the elastic element 6, and the bottom end of the elastic element 6 is fixedly connected to the top surface of the chassis 7. The high-speed rotation of the drive assembly 3 generates slight vibration, which causes the elastic element 6 to elastically contract to reduce vibration and noise. The top surface of the vacuum chamber 1 is provided with guide plates 8 extending downward on both sides of the suction device 4, which play the role of guiding the airflow.

[0024] Among them, such as Figure 3-4 As shown, the intake device 4 and the exhaust device 5 have a gradually expanding and contracting structure, which allows the gas to transition more smoothly when entering and exiting the cavity, reducing the noise caused by sudden changes in gas flow rate.

[0025] Among them, such as Figure 5 As shown, the inner wall structure of the vacuum chamber 1 is wavy. This structure can disrupt the flow path of the gas in the vacuum chamber 1, reduce the regular reflection between the gas and the chamber wall, and thus reduce the noise generated by gas friction and turbulence.

[0026] Among them, such as Figure 6 As shown, the elastic element 6 includes a telescopic column 601, a spring 602, and a telescopic cylinder 603. The bottom surface of the telescopic column 601 is fixedly connected to the telescopic cylinder 603 via the spring 602. The top end of the spring 602 is fixedly connected to the telescopic column 601, and the bottom end of the spring 602 is connected to the bottom of the inner wall of the telescopic cylinder 603. The telescopic cylinder 603 has a sliding groove that matches the telescopic column 601. The rubber assembly includes an upper shock-absorbing pad 901 and a lower shock-absorbing pad 902. The telescopic column 601 is fixedly connected to the air outlet device 5 via the upper shock-absorbing pad 901, and the telescopic cylinder 603 is fixedly connected to the chassis 7 via the lower shock-absorbing pad 902. The upper shock-absorbing pad 901 and the lower shock-absorbing pad 902 can absorb vibration energy that cannot be completely eliminated, further reducing the vibration transmission of the system.

[0027] Among them, such as Figure 7As shown, the drive assembly 3 includes a rotary motor 301 and a claw rotor 302. The claw rotor 302 is sleeved on the output end of the rotary motor 301. The rotary motor 301 is connected to the mounting base through an elastic damping pad (not shown in the figure), which can effectively absorb the vibration generated during operation.

[0028] In practical use: the rotary motor 301 drives the claw rotor 302 to rotate at high speed inside the vacuum chamber 1, drawing in gas from the suction device 4 and then discharging it from the exhaust device 5. The vibration generated during the operation of the drive component 3 can be further reduced by the cooperation of the elastic element 6 and the rubber component. At the same time, the wave-shaped structure of the inner wall of the vacuum chamber 1 can disrupt the flow path of the gas in the vacuum chamber 1 and reduce the regular reflection between the gas and the chamber wall.
