Material suction and discharge crushing fan

Abstract

The utility model discloses a crushing fan for the suction and the discharge of materials, which comprises a casing, a casing air inlet, a casing air outlet, an impeller, an impeller blade, an impeller air outlet, a blade air outlet, an impeller inner flow channel, an impeller shaft sleeve, an impeller blade disc, an impeller intermediate reinforced plate, a casing inner flow channel, a casing axial sidewall, and a casing radial sidewall. The crushing fan is characterized in that the impeller inside the fan is provided with material crushing teeth. The material crushing teeth are connected with the through-flow part of the impeller. Compared with existing various special material crushing machinery, the above crushing fan is simple in mechanical equipment, raw-material-saving to machine and manufacture, convenient to convey, install and use, manpower-saving, material-saving, financial resource-saving, multiple in usage purpose and wide in application range. By means of the crushing fan, various crude blocks, particles and powdery finished product materials of different thickness requirements can be machined. When the crushing fan is used for crushing, machining and conveying materials, the crushing fan is good in effect, high in efficiency and saving-energy.

Description

technical field [0001] The invention relates to a material suction and discharge crushing fan, which belongs to the technical field of gas machinery. Background technique [0002] Although the various material suction and discharge backflow fans and synchronous backflow fans used by people can directly suck and discharge various solid materials, they cannot be directly used for solid materials with large volume and area, and for solid materials that are easy to hang and entangle. Suction and discharge: For materials that need to be crushed, they cannot be directly crushed, but can only simply suck and discharge solid materials to be crushed, and can only simply suck and discharge solid materials that have been crushed and processed by other crushing machines, resulting in various suction and discharge materials. And the synchronous afterflow blower all have certain limitation, and the scope of use is narrow, and function is few, and purpose is few, can not adapt to people's ...

Problems solved by technology

[0002] Although the various material suction and discharge backflow fans and synchronous backflow fans used by people can directly suck and discharge various solid materials, they cannot be directly used for solid materials with large volume and area, and for solid materials that are easy to hang and entangle. Suction and discharge: For materials that need to be crushed, they cannot be directly crushed, but can only simply suck and discharge solid materials to be crushed, and can only simply suck and discharge solid materials that have been crushed and processed by other crushing machines, resulting in various suction and discharge materials. Both the fan and the synchronous backflow fan have certain limitations, the use range is narrow, the functions are few, and the uses are few, and they cannot meet the needs of people's multi-faceted use at the same time.
