The four corners of the bottom of the frame 1 are vertically fixed to the support legs 9. The arrangement of the support legs 9 can provide a good limiting support effect for the frame 1.

[0023] See also Figure 3 The utility model provides an adjustable screening device for kaolin processing through improvement. The auxiliary structure 5 includes a flip structure 51, a screening plate 52 and a screening hole 53. The left end of the flip structure 51 is fixed to the screening plate 52 as a whole. The hole spacing of the screening holes 53 opened on the screening plate 52 is smaller than the hole spacing opened on the left half of the screening frame 3. The screening hole 53 is opened on the inner side of the screening plate 52. The middle part of the inner side of the protective shell 4 is fixed to the flip structure 51. The setting of the screening hole 53 can screen the kaolin well.

[0024] See also Figure 4 The utility model provides an adjustable screening device for kaolin processing through improvement. The flip structure 51 includes a rotating wheel 511, a slot 512, an inner ring plate 513, a handle 514, a first fixing ring 515 and a second fixing ring 516. Slots 512 are provided at the upper and lower ends of the rotating wheel 511. The middle part of the inner side of the rotating wheel 511 is fixed to the inner ring plate 513 as a whole. The right end of the inner ring plate 513 is fixed to the handle 514. The handle 514 is cylindrical, and the outer surface of the handle 514 is provided with anti-slip grooves. The upper and lower ends of the rotating wheel 511 are movably fitted with the first fixing ring 515 and the second fixing ring 516 respectively. The outer sides of the first fixing ring 515 and the second fixing ring 516 are fixed to the protective shell 4. The outer side of the inner ring plate 513 is fixed to the screening plate 52 as a whole. The anti-slip grooves provided on the outer surface of the handle 514 can well prevent the hand from slipping.

[0025] See also Figure 5The utility model provides an adjustable screening device for kaolin processing through improvement. The second fixed ring 516 includes a ring body 5161, a limit frame 5162, a spring 5163 and a protrusion 5164. A limit frame 5162 is provided on the inner side of the ring body 5161. The inner bottom of the limit frame 5162 is vertically fixed to the spring 5163. There are two springs 5163 in total, and the springs 5163 are symmetrically distributed along the transverse center axis of the limit frame 5162. The top of the spring 5163 is fixed to the protrusion 5164 as a whole. The lower end of the ring body 5161 is fixed to the protective shell 4. The outer side of the protrusion 5164 is movably fitted with the slot 512. The spring 5163 can play a reciprocating lifting effect on the protrusion 5164, thereby playing a rotating locking effect on the rotating wheel 511.

[0026] The working process is as follows:

[0027] First, the staff can first place the device horizontally at the place where it needs to be used, wherein the vertically fixed support legs 9 at the lower end of the frame 1 can play a good limiting support effect, and then connect the external power supply device to the device, and use the control device of the device to start the motor 2. The output shaft of the motor 2 will drive the screening frame 3 to rotate. During this process, the staff can pour the kaolin to be screened into the feed hopper 6, and the kaolin will then enter the screening frame 3 for screening;

[0028] Second, during the operation of the motor 2, the screening frame 3 will rotate in the protective housing 4, thereby the kaolin will move from left to right in the screening frame 3. After screening by the screening frame 3, kaolin of different sizes will be discharged from the first discharge port 7 and the second discharge port 8 respectively. However, when it is necessary to screen kaolin of smaller size, the staff will turn the handle to rotate the wheel 511 in the first fixing ring 515 and the second fixing ring 516;

[0029] 3. During the rotation of the rotating wheel 511, the force generated by the staff bending the handle 514 will compress the spring 5163, causing the protrusion 5164 to retract into the limit frame 5162, thereby facilitating the rotation of the rotating wheel 511 on the fixed ring until the protrusion 5164 rotates to the slot 512 opened on the next rotating wheel 511. The spring 5163 is no longer compressed, and the generated spring potential energy will have the effect of limiting the rotation of the rotating wheel 511 until the screening plate 52 fixed on the inner ring plate 513 is rotated to the required position, so that smaller kaolin can be screened.

[0030] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field.
