Description

Technical Field

[0001] This utility model relates to the field of blower technology, and in particular to a self-adjusting mechanism for an air magnetic levitation centrifugal blower. Background Technology

[0002] Air magnetic levitation centrifugal blowers are devices that use magnetic force to achieve airflow transmission. They are widely used in fields requiring high efficiency and low noise, avoiding traditional mechanical contact, reducing friction loss, improving energy efficiency, and having a longer service life. They ensure that the blower always maintains optimal operating conditions during operation. The self-adjusting mechanism design can automatically adjust the blower's operating state according to the actual working conditions of the blower, optimizing its performance.

[0003] CN116857207A discloses an air-suspended centrifugal blower for avoiding large-amplitude airflow oscillations. The blower includes a centrifugal blower housing, a high-speed permanent magnet motor housed within the housing, and an impeller connected to the output shaft of the high-speed permanent magnet motor within a volute. A suction chamber is connected to the middle of the volute. An adjustment mechanism for adjusting the blade tip clearance is provided on the impeller shaft. The invention also discloses the manufacturing process for the air-suspended centrifugal blower, which involves performing dynamic balancing tests on the impeller shaft and impeller, followed by assembling radial and axial bearings; assembling the impeller into the volute and mounting it onto the high-speed permanent magnet motor; installing and fixing sound insulation cotton on the inner wall of the housing, and then installing the high-speed permanent magnet motor into the housing. This invention can effectively control the blade tip clearance to prevent surge, especially at low flow rates, by reducing the blade tip clearance and increasing the impeller outlet back pressure; ensuring that the flow rate entering the suction chamber blades leaves the surge zone, effectively preventing surge.

[0004] However, the self-adjusting mechanism of this air magnetic levitation centrifugal blower has the following disadvantages: during the operation of the air magnetic levitation centrifugal blower, it sucks in large particles, dust, dirt and other foreign objects, which causes the airflow channel to be blocked, resulting in insufficient airflow, reduced blower efficiency, and even failure of the self-adjusting mechanism, leading to equipment damage and shutdown. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention aims to solve the problem that, during the operation of an air magnetic levitation centrifugal blower, the ingestion of large particles, dust, dirt, and other foreign objects can lead to blockage of the airflow channel and malfunction, resulting in insufficient airflow, affecting the blower's performance, stability, and efficiency, and even causing the self-adjusting mechanism to malfunction, leading to equipment damage and shutdown. The invention provides a self-adjusting mechanism for an air magnetic levitation centrifugal blower.

[0006] To solve the above technical problems, this utility model achieves the following solution: a self-adjusting mechanism for an air magnetic levitation centrifugal blower, comprising a blower body, an air inlet pipe A fixedly connected to one side of the blower body, a filter assembly fixedly connected to one end of the air inlet pipe A, a heat dissipation tank sleeved on the surface of the blower body, and a heat dissipation assembly inserted inside the heat dissipation tank; the filter assembly includes a filter tank fixedly connected to one end of the air inlet pipe A, a spiral brush rotatably connected to the middle of the filter tank, and a motor rotatably connected to the other end of the spiral brush; the heat dissipation assembly includes a liquid inlet pipe fixedly connected to the inside of the heat dissipation tank, a multi-branch diversion pipe fixedly connected to one side of the liquid inlet pipe, and an outlet pipe fixedly connected to the other end of the diversion pipe.

[0007] As a further embodiment of this utility model, a flange is fixedly connected to one end of the filter barrel, and a slag discharge pipe is provided at the bottom of the flange. The slag discharge pipe is designed to remove impurities, waste and sediment generated during the filtration process, prevent excessive accumulation of impurities from affecting the filtration effect, and ensure the stability and long-term smooth operation of the blower.

[0008] As a further embodiment of this utility model, a spiral fan blade is fixedly connected to the inner side of the spiral brush, and a spiral shaft is fixedly connected to the middle of the spiral fan blade. The spiral brush is designed to clean the surface of the filter barrel by rotating, thereby removing dust, impurities, etc.

[0009] As a further embodiment of this utility model, a gearbox is fixedly connected to one end of the motor, and a protective shell is fitted onto the surface of the motor. The motor's design ensures a fixed connection between the motor and the gearbox, enabling effective power transmission and allowing the spiral brush to rotate, effectively removing dust and impurities from the surface of the filter barrel.

[0010] As a further embodiment of this utility model, the top of the heat sink is provided with a slot, and one end of the liquid inlet pipe is fixedly connected to a control valve. By setting the control valve, the flow rate in the liquid inlet pipe can be adjusted. Through the control valve, the flow of coolant can be precisely controlled, ensuring that the coolant flow in the heat sink is stable and that it operates within a suitable temperature range.

[0011] As a further embodiment of this utility model, one end of the air inlet pipe A is fixedly connected to a connecting pipe, and the top of the connecting pipe is fixedly connected to an air inlet pipe B. The air inlet pipe B ensures smooth airflow. Through the fixed connection, the air inlet pipe B can introduce external air and transmit it to the subsequent parts through the connecting pipe.

[0012] As a further embodiment of this utility model, a base is fixedly connected to the bottom of the blower body, a support plate is fixedly connected to the surface of the base, and an air outlet pipe is fixedly connected to the top of the blower body. The support plate provides additional support and stability, and ensures that the base will not deform or be damaged when bearing the weight of the blower and the pressure during operation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The self-adjusting mechanism of this air magnetic levitation centrifugal blower, through the setting of the filter components, prevents airflow channel blockage. During equipment operation, air flowing in through the air inlet pipe B enters the filter barrel through the connecting pipe. Simultaneously, the motor starts, driving the spiral shaft to rotate through the gearbox, causing the spiral fan blades to rotate, which in turn drives the spiral brush to rotate. Under the action of the inclined angle of the filter barrel, it can block impurities, dust, and other substances in the air, ensuring the cleanliness of the gas. Particulate matter, dust, dirt, and other foreign objects in the air adhere to the inner wall of the filter barrel. Under the action of the spiral brush, it helps to remove the dust and impurities accumulated in the filter barrel, ensuring the continuity of filtration efficiency. The spiral brush carries the filter cake to the discharge port at one end of the filter screen and discharges it into the discharge pipe. This effectively reduces the workload of manually cleaning the filter element and replacing the filter media, ensures smooth airflow, prevents airflow obstruction, and extends the service life of the equipment.

[0015] 2. The self-adjusting mechanism of this air magnetic levitation centrifugal blower, through the setting of the heat dissipation components, prevents the blower motor and other key components from overheating. The magnetic levitation blower usually uses magnetic force to support the rotor, which reduces mechanical wear, but also increases the thermal load on the magnet and its drive system, especially under high load and long-term operation. Insufficient cooling of the magnetic levitation system leads to the inability to dissipate heat in time. Coolant enters the heat dissipation tank through the inlet pipe, and then enters the distribution pipe in the heat dissipation tank. The coolant draws in heat from the blower through the distribution pipe. The coolant flows through the distribution pipe in the heat dissipation tank, and the air around the pipe carries away the heat, starting a new heat exchange cycle, carrying the heat to the outlet pipe. The coolant continuously circulates, thereby effectively controlling the temperature stability of the air magnetic levitation centrifugal blower, ensuring the stability and long-term efficient operation of the blower, preventing the components from being damaged due to excessive temperature, and extending the service life of the equipment.

Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1: The specific structure of this utility model is as follows:

[0024] Please refer to the appendix. Figures 1 to 4 This utility model provides a technical solution: a self-adjusting mechanism for an air magnetic levitation centrifugal blower, including a blower body 1, an air inlet pipe A2 fixedly connected to one side of the blower body 1, a filter assembly 3 fixedly connected to one end of the air inlet pipe A2, a heat dissipation tank 4 sleeved on the surface of the blower body 1, and a heat dissipation assembly 5 inserted inside the heat dissipation tank 4; the filter assembly 3 includes a filter barrel 301 fixedly connected to one end of the air inlet pipe A2, a spiral brush 302 rotatably connected to the middle of the filter barrel 301, and a motor 303 rotatably connected to the other end of the spiral brush 302; the heat dissipation assembly 5 includes a liquid inlet pipe 501 fixedly connected to the inside of the heat dissipation tank 4, a multi-branch diversion pipe 502 fixedly connected to one side of the liquid inlet pipe 501, and a liquid outlet pipe 503 fixedly connected to the other end of the diversion pipe 502.

[0025] One end of the filter barrel 301 is fixedly connected to a flange 6, and a slag discharge pipe 7 is provided at the bottom of the flange 6. The slag discharge pipe 7 is designed to remove impurities, waste and sediment generated during the filtration process, prevent excessive accumulation of impurities from affecting the filtration effect, and ensure the stability and long-term smooth operation of the blower.

[0026] The spiral brush 302 is fixedly connected to the inner side of a spiral fan blade 8, and a spiral shaft 9 is fixedly connected to the middle of the spiral fan blade 8. The spiral brush 302 is designed to clean the surface of the filter barrel 301 by rotating, removing dust, impurities and other contaminants.

[0027] One end of the motor 303 is fixedly connected to the gearbox 10, and a protective shell 11 is fitted onto the surface of the motor 303. The motor 303 serves to ensure that the power can be effectively transmitted by fixing the motor 303 and the gearbox 10, so that the spiral brush 302 can rotate and effectively remove dust and impurities from the surface of the filter canister 301.

[0028] The top of the heat sink 4 has a slot, and one end of the liquid inlet pipe 501 is fixedly connected to a control valve 12. The control valve 12 is used to regulate the flow rate in the liquid inlet pipe 501. The flow of coolant can be precisely controlled through the control valve 12 to ensure that the coolant flow in the heat sink 4 is stable and that it operates within a suitable temperature range.

[0029] One end of the air inlet pipe A2 is fixedly connected to the connecting pipe 13, and the top of the connecting pipe 13 is fixedly connected to the air inlet pipe B14. The air inlet pipe B14 ensures smooth airflow. Through the fixed connection, the air inlet pipe B14 can introduce external air and transmit it to the subsequent parts through the connecting pipe 13.

[0030] A base 15 is fixedly connected to the bottom of the blower body 1, and a support plate 16 is fixedly connected to the surface of the base 15. Through the setting of the support plate 16, an air outlet pipe 17 is fixedly connected to the top of the blower body 1, which provides additional support and stability for the support plate 16. The support plate 16 ensures that the base 15 will not be deformed or damaged when bearing the weight of the blower and the pressure during operation.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When preventing the airflow channel from being blocked, during the operation of the equipment, the air flowing in through the air inlet pipe B14 enters the filter barrel 301 through the connecting pipe 13. At the same time, the motor 303 is started, and the gearbox 10 drives the spiral shaft 9 to rotate, causing the spiral fan blade 8 to rotate, which in turn drives the spiral brush 302 to rotate. Under the action of the tilt angle of the filter barrel 301.

[0033] The second step: It can block impurities, dust and other substances in the air to ensure the cleanliness of the gas. Particulate matter, dust, dirt and other foreign objects in the air adhere to the inner wall of the filter barrel 301. Under the action of the rotating spiral brush 302, it helps to remove the dust and impurities accumulated in the filter barrel 301, ensuring the continuity of filtration efficiency. The spiral brush 302 causes the filter residue to be carried into the discharge port at one end of the filter screen and discharged, and then the filter residue enters the discharge pipe 7.

[0034] The third step: When preventing the blower's drive structure and other key components from overheating, the magnetic levitation blower usually uses magnetic force to support the rotor. This reduces mechanical wear, but also increases the thermal load on the magnet and its drive system. Especially under high load and long-term operation, the magnetic levitation system is not cooled enough, causing the heat to not be dissipated in time. The coolant enters the heat sink 4 through the inlet pipe 501, and then enters the distribution pipe 502 in the heat sink 4. The coolant draws in the heat from the blower through the distribution pipe 502. The coolant flows through the distribution pipe 502 in the heat sink 4, and the air around the pipe carries away the heat, starting a new heat exchange cycle. The heat is carried into the outlet pipe 503, and the coolant continues to circulate.

[0035] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
