Description

Technical Field

[0001] The utility model relates to the technical field of heavy metal recovery, in particular to an on-line recovery device for electroplated heavy metal nickel. Background Technique

[0002] The water quality of electroplating wastewater is complex and its components are not easy to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver and cyanide, etc., and some are highly toxic substances that are carcinogenic, teratogenic and mutagenic.

[0003] In the process of treating electroplating wastewater with a relatively high content of heavy metal nickel, the main recovery of metallic nickel is realized through an ion exchanger. In the actual implementation process, the ion exchange cylinder is filled with ion exchange resin, and then the wastewater is introduced into the inner cavity of the ion exchange cylinder, so that the ion exchange resin can absorb metallic nickel. However, during the actual exchange treatment, when the wastewater is directly introduced into the exchange cylinder, the wastewater is unevenly distributed, resulting in excessive use of local ion exchange resin, while some ion exchange resin is not used. And after the ion exchange resin is used for a certain period of time, it needs to be exported for treatment, and the treatment of wastewater needs to be stopped, thus affecting the efficiency of wastewater treatment. Therefore, we propose an on-line recovery device for electroplated heavy metal nickel. Content of the Utility Model

[0004] The purpose of the utility model is to provide an on-line recovery device for electroplated heavy metal nickel, which solves the problems put forward in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an on-line recovery device for electroplated heavy metal nickel, including an exchange cylinder, the number of the exchange cylinders is two, the top of the exchange cylinder is movably penetrated by a rotary joint, the tops of the two rotary joints are respectively fixedly communicated with both ends of a connecting pipe, the outer wall of the connecting pipe is fixedly communicated with a water inlet pipe, the tail end of the rotary joint is fixedly communicated with a movable pipe, a plurality of uniformly distributed water outlet holes are opened at the bottom of the movable pipe, a filter screen plate is obliquely fixed on the lower side of the inner cavity of the exchange cylinder, a toothed ring is fixedly sleeved on the outer wall of the rotary joint, and a gear is meshed with the outer wall of the toothed ring, and the gear is fixed to the outer end of the transmission shaft of a servo motor.

[0006] By adopting the above technical scheme, the wastewater is introduced into the inner cavity of the exchange cylinder, and ion exchange resin particles are filled in the inner cavity of the exchange cylinder. Then, after the wastewater enters the rotary joint, it will enter the movable pipe and be discharged along the water outlet holes. At the same time, starting the servo motor can drive the gear to rotate, thereby driving the toothed ring to rotate, so that the rotary joint drives the movable pipe to rotate, and further enables the movable pipe to evenly distribute water at the top of the inner cavity of the exchange cylinder, so that the ion exchange resin particles are fully utilized, and the utilization rate is improved.

[0007] As a preferred embodiment of the present utility model, electromagnetic valves are fixedly connected to both ends of the communicating pipe.

[0008] By adopting the above technical solution, after the ion exchange resin in a single exchange cylinder has been used for a certain period of time, the corresponding electromagnetic valve can be closed, and then another electromagnetic valve can be opened, so that the wastewater is introduced into another exchange cylinder for treatment, thereby realizing continuous and uninterrupted wastewater treatment and ensuring the efficiency of wastewater treatment.

[0009] As a preferred embodiment of the present utility model, a discharge port is provided on the outer wall of the exchange cylinder near the filter mesh plate, and a cover plate is fixed at the discharge port by bolts.

[0010] By adopting the above technical solution, the setting of the cover plate enables the fully absorbed ion resin particles to be directly exported for treatment by opening the cover plate.

[0011] As a preferred embodiment of the present utility model, a feed port is provided on one side of the top of the exchange cylinder, and an end cover is threadedly connected to the feed port.

[0012] By adopting the above technical solution, the setting of the feed port facilitates the introduction of ion exchange resin into the exchange cylinder.

[0013] As a preferred embodiment of the present utility model, a drain pipe is fixedly communicated with the bottom of the exchange cylinder.

[0014] By adopting the above technical solution, the setting of the drain pipe enables the wastewater from which nickel has been removed to be exported for further treatment.

[0015] As a preferred embodiment of the present utility model, the top of the servo motor is fixedly connected to the top of the exchange cylinder through a fixing frame.

[0016] By adopting the above technical solution, the high stability of the servo motor during use can be ensured.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] An electroplating heavy metal nickel online recovery device of the technical solution of the present application can drive the gear to rotate through the servo motor, thereby enabling the toothed ring to rotate, and further enabling the rotary joint to drive the movable pipe to rotate. Thus, when the movable pipe is used to replenish water into the inner cavity of the exchange cylinder, the sewage can be evenly distributed in the exchange cylinder, so that the ion exchange resin filled in the inner cavity of the exchange cylinder can be fully utilized, avoiding the situation of local non-use, and improving the utilization rate of the ion exchange resin;

[0019] By closing one solenoid valve and opening another solenoid valve, it is possible to enable another exchange cylinder for recycling after the ion exchange resin in a single exchange cylinder is fully absorbed, and by opening the end plate, the ion exchange resin to be processed can be directly exported, which is convenient to operate, thus not affecting the continuity of wastewater treatment and further ensuring the efficiency of wastewater treatment.

[0029] Furthermore, a drain pipe 11 is fixedly connected to the bottom of the exchange cylinder 1. The setting of the drain pipe 11 enables the wastewater with nickel removed to be discharged and processed again;

[0030] Even further, a discharge port is provided on the outer wall of the exchange cylinder 1 near the filter mesh plate 13, and a cover plate 12 is fixed at the discharge port by bolts.
