Description

Technical Field

[0001] The utility model relates to the technical field of airflow screens, in particular to a novel airflow screen wind wheel. Background Art

[0002] The current air flow screen uses the blades in the screen cylinder to make the material simultaneously subjected to centrifugal force and cyclonic propulsion force, thereby forcing the material to be ejected through the screen to achieve the screening purpose.

[0003] The impeller blades are important components of the air flow screen, which directly affect the screening output and accuracy. The blades currently used are square tooth blades, flat blades and T-shaped blades. The burrs during processing are difficult to handle, which leads to pollution of the material source. Secondly, the weight is too heavy, which causes the shaft to sag and deform for a long time, and the material cannot be quickly ejected through the screen and taken away. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a new air flow screen impeller, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a novel airflow screen impeller, which adopts the technical solution of comprising a shaft tube. The shaft tube is provided with a blade support plate, and there are multiple blade support plates, which are arranged in an array on the shaft tube. The two adjacent blade support plates are a first blade support plate and a second blade support plate, a first fixed slot is provided on the first blade support plate, and a second fixed slot is provided on the second blade support plate. The blades are provided on the blade support plates, which are engineering plastics. The blades are connected to the blade support plates through the first fixed slot and the second fixed slot. The first fixed slot and the second fixed slot are staggered at a certain angle. A material retaining plate is provided at the end of the shaft tube, and a screen is provided on the outside of the blade. The distance between the blade and the screen is 4mm to 6mm, and the diameter of the material retaining plate is 4mm to 10mm smaller than the screen.

[0006] As an optimal technical solution of the present invention, a first fixed groove and a second fixed groove are provided at both ends of the blade, the first fixed groove is inserted into the inside of the first fixed slot, and the second fixed groove is inserted into the inside of the second fixed slot, so that the blade has a gradual angle change, and the material is in a spiral wind swirling state during the screening process, which is more effective in fully screening the material.

[0007] As a preferred technical solution of the present invention, there are multiple first fixed slots and second fixed slots, and they are arranged in a circular array to the blade support plate. Multiple groups of blades can quickly blow the material through the screen. The blade support is used to block the material to prevent the material from quickly passing through the wind wheel and being discharged, so that the input material can be fully screened, thereby ensuring the screening accuracy and greatly improving production efficiency.

[0008] As an optimal technical solution of the present invention, a second fixing hole is opened on the blade bracket, and first fixing holes are opened on both sides of the blade. A steel wire rope passes through the first fixing hole, and the steel wire rope is tightened and fixed to the inside of the second fixing hole by bolts.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: the blades are made of engineering plastic material, and no sparks are generated when the blades rub against the screen during rotation, thereby reducing the occurrence of safety accidents. In addition, steel may have small burrs that cannot be handled, leading to the hidden danger of contaminating the raw materials, while this type of engineering plastic blade will not have the above risks. The blade support plate and the material baffle can block the moving speed of the material, preventing the material from being discharged too quickly from the slag discharge port on the left, thereby ensuring the screening accuracy and improving production efficiency. The spiral wind generated by the rotation of the blades can quickly blow the material through the screen. BRIEF DESCRIPTION OF THE DRAWINGS
