[0025] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0026] This specific embodiment relates to a waste liquid recovery device for a dyeing machine, such as Figure 1 As shown, it includes a recycling box 100, and several groups of conveying roller groups 110 for squeezing cloth are arranged in the recycling box 100. Each group of conveying roller groups 110 includes two conveying rollers, and each conveying roller group 110 is placed in the horizontal direction. The conveying rollers in each group are spaced apart in the vertical direction. During the transportation of cloth, the cloth will be clamped between the conveying roller groups 110. In the recycling box 100, at least two groups of transport rollers are arranged. The number of conveying roller groups 110 can be increased according to the actual production needs. The conveying roller group 110 is rotated by a motor. The bottom surface of the recycling box 100 is provided with a bottom plate 300 for preventing dye leakage. The bottom plate 300 also has the function of stabilizing the recycling box 100.

[0027] like Figure 1 As shown, the gap in the conveying roller set 110 decreases in sequence along the moving direction of the cloth. The conveying roller set 110 includes a first squeezing roller set 120 and a second squeezing roller set 130, both of which are used to pass the cloth, and the gap between the second squeezing roller sets 130 is smaller than the gap between the first squeezing roller sets 120. The first squeezing roller set 120 and the second squeezing roller set 130 are both used to squeeze the cloth. The first squeezing roller set 120 first squeezes the cloth preliminarily, and then the second squeezing roller set 130 squeezes the cloth again, thereby achieving a good squeezing effect.

[0028] like Figure 1 , Figure 3-Figure 5As shown, a filter assembly 200 for filtering the waste liquid squeezed out by the conveying roller group 110 is located in the recovery box 100 below the squeezing roller, and the filter assembly 200 is located below the conveying roller group 110. The filter assembly 200 is used to filter impurities in the dye. The filter assembly 200 includes a first filter net 210 for preliminary filtering and a second filter net 220 for secondary filtering. The mesh diameter of the first filter net 210 is larger than the mesh diameter of the second filter net 220. The first filter net 210 is used to filter larger impurities in the dye, such as fiber impurities and solid impurities of the cloth; the second filter net 220 is used to filter smaller impurities in the dye. The first filter net 210 is located above the second filter net 220, so that the first filter net 210 can filter the waste liquid by gravity, and then flow to the second filter net 220, and the second filter net 220 performs secondary filtering. The dye is initially physically filtered by the first filter net 210 and the second filter net 220. A drain port 140 for discharging the waste liquid after filtering is provided on the side wall of the recovery box 100. The filtered dye is discharged to other processes through the drain port 140, such as reprocessing the dye by chemical means. The first filter net 210 and the second filter net 220 can be detachably connected in the recovery box 100, so that the first filter net 210 and the second filter net 220 are easy to replace. The first filter net 210 and the second filter net 220 are both fixed in the recovery box 100 by snap-fitting, and the staff releases the button by snap-fitting to take the first filter net 210 and the second filter net 220 out of the recovery box 100. When the service life of the first filter net 210 and the second filter net 220 expires, the staff can directly remove the first filter net 210 and the second filter net 220, and then replace them with new first filter net 210 and the second filter net 220.

[0029] like Figure 1 and Figure 2As shown, a stirring unit 400 is provided in the recycling box 100. The stirring unit 400 is used to add cleaning liquid into the recycling box 100 after the dye treatment is completed. The stirring unit 400 is used to stir the cleaning liquid so that the cleaning effect in the recycling box 100 is better. The stirring unit 400 includes a stirring rod 410 that is arranged in the recycling box 100 and driven by a rotating motor. The stirring rod 410 is installed at the driving end of the motor and rotates under the drive of the motor. The stirring rod 410 passes through the side wall of the recycling box 100. The stirring rod 410 is located between the squeezing roller and the filter assembly 200, so that the stirring rod 410 can stir the cleaning liquid in the recycling box 100. The end face of the stirring rod 410 is provided with a cushion block 411. The cushion block 411 is a cylindrical rubber block, which is used to prevent the stirring rod 410 from extending too long and contacting the other side wall of the recycling box 100, thereby damaging the recycling box 100. The stirring rod 410 is provided with a plurality of stirring blades 420, which may be single blades or double blades, for stirring the cleaning liquid in the recovery box 100. The stirring blades 420 are located above the fabric to avoid damaging the fabric. The surfaces of the stirring blades 420 are provided with stirring protrusions at intervals. The stirring protrusions are used to increase the contact area between the stirring blades 420 and the cleaning liquid, thereby achieving a better stirring effect.

[0030] Working principle: Figure 4 As shown, Figure 4 The movement path of the fabric is shown in FIG. Through the conveying roller set 110, the excess dye in the fabric will drip into the recovery box 100. In the recovery box 100, a first filter 210 and a second filter 220 are set to preliminarily filter the impurities in the dye. The filtered dye will flow out through the drain port 140 and be transferred to other processing procedures.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
