[0002] Turbine blower is an efficient and stable air conveying equipment, widely used in many fields, including sewage treatment, chemical industry, metallurgy, pneumatic transportation, material handling, printing industry and packaging machinery.

[0003] A turbo blower is mainly composed of a motor, turbine, impeller, casing and other main components. The motor provides power, the turbine converts the rotation of the motor into high-speed rotation, and the impeller is responsible for sucking in and pressurizing the air, and finally transporting the air to the required location through the casing. The existing turbo blower has a fast speed and a large air intake, and the air intake channel is a horizontal straight line, which causes high-speed airflow to directly wash the impeller. Long-term operation causes the impeller to deform, contact and wear each other, reducing the safety of the turbo blower.

[0004] Therefore, it is necessary to redesign the turbo blower to effectively prevent the problem that the turbo blower has a high speed and a large air intake, and the air intake channel is a horizontal straight line, which causes the high-speed airflow to directly wash the impeller, and long-term operation causes the impeller to deform and contact and wear each other.

[0024] Turbine housing 1;

[0025] The front end of the turbine housing 1 is connected to an air intake pipe 2, and the front end of the air intake pipe 2 is fixedly connected to a processing mechanism 3;

[0026] The processing mechanism 3 includes a cylinder 31, a hollow ring 32, a conical barrel 33, a guide bend 34, a turntable 35, a tripod 36 and a blade 37. The front end of the intake pipe 2 is fixedly connected to the cylinder 31, the front end of the inner cavity of the cylinder 31 is fixedly connected to the hollow ring 32, the back end of the hollow ring 32 is connected to the conical barrel 33, the back end of the conical barrel 33 is connected to the guide bend 34, the back end of the guide bend 34 passes through the interior of the turbine casing 1, the inner cavity of the hollow ring 32 is movably connected to the turntable 35 through a bearing, the inner side of the turntable 35 is longitudinally fixedly connected to the tripod 36, and the front end of the tripod 36 is fixedly connected to the blade 37.

[0027] refer to Figure 3 The surface of the conical barrel 33 and the surface of the turntable 35 are both provided with air inlet grooves 4, and the number of the air inlet grooves 4 is several and evenly distributed.

[0028] As a technical optimization solution of the present invention, the provision of the air inlet groove 4 can assist the conical barrel 33 and the turntable 35 in circulating air, thereby avoiding the conical barrel 33 and the turntable 35 being solid and affecting the speed of air flow.

[0029] refer to Figure 4 An air duct groove 5 is provided on the inner side of the guide elbow 34 , and the air duct groove 5 is used in conjunction with the guide elbow 34 .

[0030] As a technical optimization solution of the present invention, the provision of the air duct groove 5 can assist the guide bend 34 in working, thereby avoiding the occurrence of wake turbulence when the high-speed airflow is discharged through the guide bend 34.

[0031] refer to Figure 3 An annular groove 6 is provided in the inner cavity of the hollow ring 32 and corresponds to the position of the turntable 35 , and the annular groove 6 is used in conjunction with the turntable 35 .

[0032] As a technical optimization solution of the present invention, the provision of the annular groove 6 can assist the turntable 35 in its work and simultaneously play a role of limiting, thereby preventing the turntable 35 from being separated during the rotation process.

[0033] refer to Figure 1 The left and right sides of the surface of the turbine housing 1 are fixedly connected with reinforcing ribs 7, and the number of reinforcing ribs 7 is several and evenly distributed.

[0034] As a technical optimization solution of the present invention, the provision of the reinforcing ribs 7 can assist the turbine housing 1 in its operation and at the same time play a reinforcing role, thereby avoiding the phenomenon of deformation caused by vibration transmitted during mechanical operation inside the turbine housing 1.

[0035] refer to Figure 3 The material of the blade 37 is aluminum alloy, and the blade 37 is used in conjunction with the tripod rod 36.

[0037] The working principle and usage process of the present invention are as follows: when in use, the turbo blower is started, and the turbo blower cooperates with the air intake pipe 2 and the cylinder 31 to extract external air. The air enters the cylinder 31 and the hollow ring 32 and contacts the blades 37. The blades 37 are impacted by the high-speed airflow and rotate autonomously in accordance with the angle of the blades 37. The rotation of the blades 37 drives the tripod 36 and the turntable 35 to rotate synchronously. The turntable 35 rotates stably in accordance with the annular groove 6. Then the airflow cooperates with the air intake groove 4 of the hollow ring 32 and the conical barrel 33 to pass quickly. The conical barrel 33 cooperates with the effect of being wide in front and narrow in the back to compress, accelerate and pressurize the airflow at the rear end to enter the interior of the guide bend 34. Finally, the guide bend 34 cooperates with the bending angle to change the direction of the airflow and enter the interior of the turbine housing 1, avoiding the phenomenon of deformation and wear caused by the high-speed airflow rushing straightly against the impeller, thereby extending the service life.
