Problems solved by technology

[0003] High-pressure vortex fans are often used in various industries in industrial production, especially in the treatment of dust. Among them, in the woodworking industry, side-flow fans are often used as the power source to form negative pressure, and the woodworking cutting and planing processes are generated. A large amount of wood dust is collected and transported. When the impeller rotates, the airflow and pressure difference formed will draw the dust from the cutting place into the fan casing, and then transport it to the collection bag through the air outlet of the casing. However, in the actual processing process , the dust generated by grinding is easy to be blocked in the gully between the shell and the impeller, the continuous accumulation of dust and it is not easy to clean up will cause the impeller to stall, which will cause the motor to burn out

Embodiment 1

[0038] Embodiment 1: A kind of impeller assembly that facilitates chip removal, such as Figure 1 to Figure 7 , including the impeller 1 and the housing for accommodating the impeller 1, the housing is provided with a chip removal channel along its edge, the inner wall of the housing and the two side walls of the impeller 1 are arranged parallel to each other, and the middle part of the housing is provided with a penetrating shaft Hole 2, the impeller 1 is provided with a shaft passing portion 3 communicating with the shaft hole 2, wherein the casing includes a front pump cover 4 and a rear pump cover 5, and a concave cavity 6 for accommodating the impeller 1 is formed on the rear pump cover 5 , the inner bottom surface of the cavity 6 forms a plane parallel to the end surface of the impeller 1 .

[0039] like Figure 4 to Figure 6 As shown, the side of the front pump cover 4 facing the impeller 1 and its edge are located on the same plane, and the inside of the front pump co...

Embodiment 2

[0042]Embodiment 2: A fan, including the impeller assembly and motor as in Embodiment 1, one side of the rear pump cover 5 is provided with a bearing end cover that is detachably connected to the shaft hole 2 by means of bolt connection, and the rear pump cover 5 The cover 5 is detachably connected with silencers located at the chip outlet 9 and the chip inlet 8 .

[0043] Working process: Assemble the impeller assembly and the motor, so that the hub 11 of the impeller 1 is fixedly connected to the output end of the motor through the connecting shaft, and the hub 11 is located in the cavity 6 of the rear pump cover 5, and both sides of the hub 11 are connected to the front pump The cover 4 and the rear pump cover 5 form a flat plane with a gap, and the bearing end cover is threaded on one side of the rear pump cover 5 to connect the connecting shaft so that the impeller 1 can rotate smoothly, and the impeller 1 is driven by the motor. When rotating, the displacement of the bla...

Abstract

The invention discloses an impeller assembly facilitating chip removal and a fan, relates to ventilation equipment, and aims to solve the problems that dust is prone to being blocked in a gully between a shell and an impeller, dust is continuously accumulated and is not easy to clean, consequently, the impeller locked-rotor situation happens, and a motor is burnt out. According to the technical scheme, the impeller assembly is characterized by comprising an impeller and a shell used for containing the impeller, a chip removal channel is formed in the shell along the edge of the shell, the inner wall of the shell is parallel to the two side walls of the impeller, a through shaft hole is formed in the middle of the shell, and a shaft penetrating part communicating with the shaft hole is arranged on the impeller. Due to the fact that the inner wall of the shell and the two side walls of the impeller are arranged in parallel, accumulation of dust between the impeller and the side walls of the shell can be reduced, the problem that the rotation load acting force of the impeller is increased due to dust accumulation between the impeller and the shell is solved, the service life of the vortex fan is prolonged, friction between the impeller and the shell can be reduced, and therefore a good noise reduction effect is achieved.

Description

technical field [0001] The present invention relates to ventilating equipment, more particularly, it relates to an impeller assembly and a blower fan which are convenient for chip removal. Background technique [0002] Side flow fan, also called high pressure vortex fan, air ring vacuum pump. The impeller is directly installed on the rotor of the motor, and it is completely non-contact compression. Since the pump shaft is installed outside the compression chamber, it can ensure the maximum reliability of the machine even if it works under the maximum pressure difference. [0003] High-pressure vortex fans are often used in various industries in industrial production, especially in the treatment of dust. Among them, in the woodworking industry, side-flow fans are often used as the power source to form negative pressure, and the woodworking cutting and planing processes are generated. A large amount of wood dust is collected and transported. When the impeller rotates, the air...
