Description

Technical Field

[0001] The utility model belongs to the field of feeding dust removal devices, and particularly relates to a vibrating screen feeding dust removal device. Background Art

[0002] At present, during the processing of powder coatings, a vibrating screen is required for screening. The vibrating screen works by the reciprocating spiral vibration generated by the vibration exciter. The upper rotating weight of the vibration exciter causes the screen surface to generate a planar gyratory vibration, while the lower rotating weight causes the screen surface to generate a conical gyratory vibration. The combined effect makes the screen surface generate a compound spiral vibration. Its vibration trajectory is a complex space curve. The projection of this curve on the horizontal plane is a circle, and the projection on the vertical plane is an ellipse. By adjusting the excitation force of the upper and lower rotating weights, the amplitude can be changed. By adjusting the spatial phase angle of the upper and lower weights, the curve shape of the screen surface movement trajectory can be changed and the movement trajectory of the material on the screen can be changed. When the vibrating screen is in use, a feeding machine is required to feed the material.

[0003] However, when the existing feeding machine is in use, when feeding powdery materials, it will inevitably cause the powdery materials to overflow due to the external air flow environment, which will lead to more waste of materials.

[0004] Therefore, in view of the deficiencies of the above solutions in actual production and implementation, they are corrected and improved. At the same time, in the spirit of pursuing excellence and with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, the present utility model is created. A vibrating screen feeding dust removal device is provided to solve the problem that when the existing feeding machine is in use, when feeding powdery materials, it will inevitably cause the powdery materials to overflow due to the external air flow environment, which will lead to more waste of materials.

The four legs 101 are respectively fixedly connected to the four corner positions of the bottom end surface of the base 1. The bottom end surfaces of the four legs 101 are all fixedly connected with mounting bases 102. The main body of the mounting bases 102 is a rectangular block structure. The mounting bases 102 and the legs 101 together form a support structure for the base 1. The bottom end surface of the mounting base 102 is provided with universal wheels 103. The universal wheels 103 and the mounting base 102 together form an auxiliary moving structure. The inside of the base 1 is fixedly connected with a bracket 2, and the top end surface of the base 1 is fixedly connected with a top plate 3. A through hole is opened inside the top plate 3, and a hopper 302 is fixedly connected inside the through hole. The top end surface of the top plate 3 is fixedly connected with a cover 301. A through hole is opened on the outer side of the cover 301 for feeding. A driver 303 is installed on the top end surface of the cover 301. The bottom end of the driver 303 is provided with an output shaft, and a stirring member 304 is installed on the output shaft.

[0025] Among them, the bracket 2 is longitudinally arranged, and there are two brackets 2 in total. The two brackets 2 are fixedly connected in a linear array on the left and right sides inside the base 1. The base 1 and the bracket 2 together form a bearing structure. A recovery tray 201 is also installed on the top end surfaces of the two brackets 2. The main body of the recovery tray 201 is a structure with a one-way opening at the top. A vibration motor 202 is installed on the outer peripheral surface of the recovery tray 201. A through hole is opened on the inner bottom end surface of the recovery tray 201. The inside of the recovery tray 201 is fixedly connected with a sieve base 203. The main body of the sieve base 203 is a structure with a one-way opening at the top. A sieve mesh 204 is fixedly connected inside the sieve base 203.

[0026] Among them, the top surface height of the screen 204 is lower than that of the screen base 203, and through holes are provided on the outer peripheral surface of the screen base 203.
