The gears 311 on both sides are connected to the shaft 4, and the shaft 4 is axially arranged horizontally. The shaft 4 is driven by the motor 3 to realize rotation.

[0031] like Figure 1 , Figure 2 As shown, the outer wall of the shaft body 4 is fixedly mounted with a support assembly 6, which includes a support rod 61, combined with Figure 3There are multiple support rods 61 distributed along the circumference of the shaft body 4, and the support rods 61 are arranged in multiple layers along the radial direction of the shaft body 4. The support rods 61 are long strips and the length direction is along the axial direction of the shaft body 4. A filter component 5 is installed between two adjacent layers of support rods 61. The filter component 5 is distributed in multiple layers along the radial direction of the shaft body 4. The filter component 5 is a sponge. The two walls of the filter component 5 along the radial direction are respectively in contact with the corresponding support rods 61. The filter component 5 supports the support rods 61. The arrangement of the support rods 61 forms a gap 51 between adjacent filter components 5, which is convenient for subsequent drying. The filter component 5 is provided with a water injection groove 52, which radially passes through the filter component 5, and the length direction of the water injection groove 52 is along the axial direction of the filter component 5 and does not pass through the filter component 5. The water injection groove 52 is connected with the adjacent gap 51.

[0032] The support rod 61 can move radially along the shaft body 4. Specifically, Figure 1 , Figure 2 As shown, the support assembly 6 also includes a disk body 1 62 and a disk body 2 63.

At this time, the fluff impurities contained in the printing and dyeing wastewater are adsorbed on the filter component 5. The rotation of the turntable 2 can make the filter component 5 rotate to the drying area 9 on the right side.

After drying, the fluff on the surface of the filter component 5 is extracted through the vacuum pump connected to the connecting pipe 1 71.

[0035] A method for using a printing and dyeing wastewater pretreatment device, comprising the above-mentioned printing and dyeing wastewater pretreatment device, and the specific using steps are:

[0036] ① Such as Figure 1 As shown, waste water is introduced into the water inlet pipe 15, and the waste water is filtered by the filter component 5 and discharged from the water outlet pipe 16 at the bottom of the cavity 13. The motor 3 drives the shaft body 4 to rotate to rotate the filter component 5. When the waste water passes through the filter component 5, the waste water can enter the inner filter component 5 through the gap portion 51 and the water injection groove 52, so that the inner filter component 5 also plays a role in absorbing fluff.

[0037] ② If Figure 1 As shown, the turntable 2 is driven by the motor to rotate so that the filter component 5 on the left is transferred to the drying area 9 on the right. At this time, the insert tube 7 is located at the right extreme position, and the left end of the insert tube 7 is located on the right side of the filter component 5. The upper and lower pressure plates 8 are driven by the cylinder 81 to approach each other and squeeze the filter component 5 up and down. The support rod 61 moves radially inward along the shaft body 4, and the moisture in the filter component 5 is squeezed out and discharged from the water outlet 17.

[0038] ③ The insert tube 7 moves to the left side under the drive of the oil cylinder 73 and is inserted into the outermost filter component 5. The left end of the insert tube 7 abuts against the disk body 1 62, and dry hot air is introduced into the inner cavity 74 through the connecting pipe 2 72. The dry hot air enters the gap portion 51, thereby achieving rapid drying.

[0039] ④ After drying, the fluff on the filter component 5 falls into the inner cavity 74, and the fluff in the inner cavity 74 is extracted through a vacuum pump connected to the connecting pipe 71, so that the fluff adsorbed on the filter component 5 is discharged, thereby improving the filtering efficiency of the filter component when it is used for filtering again.
