Problems solved by technology

[0002] At present, the fans on the market can only suck in or discharge the air, and cannot suck in and discharge larger particles such as red dates. Some fans will suck in some fine particles during the suction and discharge, and these particles can only be discharged through the impeller. Cannot absorb and discharge larger particles

Embodiment 1

[0021] refer to figure 1 image 3 , the fan shaft is set as a hollow shaft (5), a cavity (4) is set in the center of the blade one (2), the cavity (4) is connected to the hollow shaft (5), and an isolation net (3) is set in front of the blade one (2) , the isolation net (3) extends to the cavity (4) and the inner cavity of the hollow shaft (5).

[0022] After the fan is powered, blade one (2) rotates, and gas and particles are sucked in from the air inlet (1). Due to the effect of the isolation net (3), the particles cannot touch blade one (2) and enter along the isolation net (3) The blade cavity (4) enters the hollow shaft (5) again, and is discharged from the air outlet (8).

Embodiment 2

[0024] refer to figure 2 image 3 , when processing the impeller, the front disc section blade is processed into centrifugal blade two (9), the blade root section blade is processed into axial flow blade three (10), and the isolation net (3) is set at the front of the blade and the inner ring, and the isolation net ( 3) extending to the inner cavity of the hollow shaft (5).

[0025] When the impeller rotates, the airflow and particles enter from the air inlet (1) under the action of the centrifugal blade two (9), the particles stay in the isolation net (3), and the air flow passes through the isolation net (3) from the air outlet (7) ), the particles move inward in the isolation net (3), enter the hollow shaft (5) under the action of the axial flow blade (10) at the root section, and are blown out of the air outlet by the airflow from the third axial flow blade (10) (8).

Abstract

The fan for pumping and discharging particles of the invention belongs to the field of fans, in particular to a fan capable of sucking in and discharging particles. The air blower for exhausting particulate matter of the present invention is that the fan shaft is set as a hollow shaft, and a cavity is set in the center of the blade, and a cylinder isolation net is arranged in the cavity, and the isolation net is fixed on the shell of the air inlet. The fan provided with this device can inhale and discharge larger particles such as red dates. Particles are discharged through the fan but not through the impeller, which not only protects the impeller, but also protects the suction from damage. The installation of the device on the blower can expand the range of use of the blower, increase new uses of the blower, and has outstanding substantive features and remarkable progress.

Description

technical field [0001] The fan for pumping and discharging particles of the invention belongs to the field of fans, in particular to a fan device capable of sucking in and discharging particles. Background technique [0002] At present, the fans on the market can only suck in or discharge the air, and cannot suck in and discharge larger particles such as red dates. Some fans will suck in some fine particles during the suction and discharge, and these particles can only be discharged through the impeller. It cannot absorb and discharge larger particles. Contents of the invention [0003] The air blower for exhausting particulate matter of the present invention is to set the fan shaft as a hollow shaft, and set a cavity in the center of the blade, that is, the center of the hub. Jujube is inhaled and discharged. The particles pass through the inside of the fan but are discharged without touching the blades, which not only protects the blades, but also protects the inhaled ...
