Description

Technical Field

[0001] The utility model relates to a waste liquid treatment device for chemical nickel-phosphorus plating. Background Art

[0002] The fastest growing type of chemical nickel plating. The plating solution generally contains nickel sulfate, nickel acetate and other salts as the main salts, hypophosphite, sodium borohydride, borane, hydrazine and other reducing agents, and various additives are added. The phosphorus in the chemical nickel plating waste liquid generated by the aging of the plating solution or the cleaning of the plated parts is very harmful to the environment. If the chemical nickel plating waste liquid is directly discharged, it will cause serious environmental pollution. Therefore, it is necessary to use a waste liquid treatment device to treat the chemical nickel plating waste liquid before discharge. The functionality of the existing waste liquid treatment device is poor. It cannot fully mix and react the added reagents with the phosphorus in the chemical nickel plating waste liquid, resulting in poor phosphorus removal effect. After the waste liquid is treated, the residue on the inner wall of the waste liquid treatment device cannot be quickly cleaned, and the staff needs to clean it manually, which increases the labor intensity of the staff and is not conducive to actual operation and use.

DETAILED DESCRIPTION

[0017] Reference Figure 1-Figure 3 , a waste liquid treatment device for chemical nickel-phosphorus plating, which comprises: a box body 14, a shaft seat 9 is fixed at the center opening of the top of the box body, the shaft seat is connected to the gear ring 6 through a bearing, an adjustment opening 17 is opened on the gear ring, the adjustment opening is a rectangular opening, and two groups of adjustment screw holes 18 are opened on the upper and lower sides of the rectangular opening, the gear ring and the adjustment plate 5 of the stirring shaft 12 are fixed by bolts, and the adjustment plate is threadedly connected with a fixing bolt 19, which is connected to the adjustment screw holes at different positions to achieve the purpose of adjusting the position of the stirring shaft, and multiple groups of stirring blades 13 are fixed on the circumference of the stirring shaft;

[0018] A brush plate 11 is fixed to the stirring shaft via a connecting rod 10;

[0019] A support 1 is fixed on the box body, and the support is welded to the top of the box body through a seat rod 2. A reduction motor 3 is fixed on the support, and the output shaft of the reduction motor is fixed to a driving gear 4, and the driving gear is meshed with the gear ring.

[0020] The waste liquid treatment device for chemical nickel-phosphorus plating has a drug adding port 7 and a liquid adding port 8 on the top of the box.

[0021] The waste liquid treatment device for chemical nickel-phosphorus plating has a liquid outlet 15 at the center of the bottom of the box, and a shut-off valve 16 is installed on the liquid outlet to control whether the waste liquid flows out.

[0022] Working principle: When in use, add the chemical nickel plating waste liquid through the liquid adding port, and then add the added agent through the agent adding port. After adding, start the reduction motor, the reduction motor drives the drive gear to rotate, and the drive gear is engaged with the gear ring, thereby driving the gear ring to rotate. The stirring shaft is fixed on the gear ring. When treating the waste liquid, align and connect the fixing bolts of the adjustment plate with the adjusting screw holes in the middle of the upper and lower adjustment openings. At this time, the stirring shaft is in the center of the box. During the rotation of the gear ring, the stirring shaft rotates to achieve a full mixing reaction of the chemical nickel plating waste liquid and the agent. After the reaction is completed, the treated waste liquid is discharged through the liquid outlet. When the box needs to be cleaned, stop the reduction motor, unscrew the fixing bolts, and then adjust the position of the adjustment plate so that the screw hole on the adjustment plate is opposite to the other adjusting screw hole, and then screw on the fixing bolts. The adjusted position is as follows Figure 4 As shown, the brush of the brush plate contacts the inner wall of the box, and then the reduction motor is started so that the brush can clean the side wall of the box.
