Description

Technical Field

[0001] The invention relates to the technical field of electroplating wastewater treatment, and in particular to a treatment system for electroplating metal wastewater. Background Art

[0002] Electroplating is to place the metal product to be plated as the cathode and the coating metal as the anode in a plating solution containing the coating metal ions. Under the action of direct current, the metal ions in the plating solution obtain electrons on the surface of the cathode (the metal product to be plated) and are reduced to metal atoms, thereby forming a uniform and dense coating on the metal surface, thereby effectively improving the properties of the metal and facilitating practical use.

[0003] During the electroplating process, the electroplating wastewater generated is easily doped with metal ions, which can easily affect the environment if discharged directly. Therefore, it is necessary to treat the electroplating metal wastewater, but in the actual treatment process, there are troublesome treatment procedures, and large particle impurities in the water body will affect the actual treatment. For this reason, we propose a treatment system for electroplating metal wastewater. Summary of the invention

[0054] Reference Figure 4-Figure 6 The vibration assembly includes a motor II 23 mounted on the outside of the threaded cover 21, the output shaft of the motor II 23 extends through the inside of the threaded cover 21 and is connected to a conflicting cam 26, and the conflicting cam 26 conflicts with the bottom end of the collection bucket 22;

[0055] The guide assembly 24 is provided with several groups and is installed in a circular array inside the threaded cover 21. The guide assembly 24 includes two groups of fixed blocks 241. A guide rod 245 is fixedly connected between the fixed blocks 241. A sliding tube 242 is sleeved on the outer side of the guide rod 245.

A spring tube 243 connected to the fixed block 241 and the sliding tube 242 is sleeved on the outer side of the guide rod 245.

[0056] The vibration component drives the collection barrel 22 to vibrate up and down to realize internal metal vibration stratification, and with the help of the setting of the guide component 24, the collection barrel 22 is effectively reset to ensure the effective vibration stratification effect.

[0057] A heating pipe 25 is provided at the lower outer portion of the threaded cover 21 and is sleeved on the outer side of the collecting barrel 22 for heating the collecting barrel 22 to facilitate drying of the layered metal precipitates in subsequent actual processing.

[0058] Reference Figure 7-Figure 8 , the powder guide ring 422 is connected to the driving shaft 421 through a connecting rod, and then rotates stably with the driving shaft 421;

[0059] The driving shaft 421 includes a guide ring body 4221, and an annular guide groove is provided at the top of the guide ring body 4221, and the line connecting the highest point and the lowest point of the annular guide groove passes through the center of the guide ring body 4221, thereby ensuring that when the upper powder inlet pipe 5 injects metal powder for sewage treatment, the annular guide groove on the upper part of the guide ring body 4221 is set, so that the metal powder can always effectively fall at the lowest point of the annular guide groove of the guide ring body 4221;

[0060] The guide ring 4221 is provided with a vertical discharge hole at the lowest point of the annular guide groove. When the guide ring 4221 rotates following the driving shaft 421, the metal powder entering the guide ring 4221 can rotate along with it to achieve uniform spreading of the powder inside the processing tank 1, thereby promoting uniform reaction below.

[0061] Reference Figure 3 and Fig. 9 The bottom end of the guide ring body 4221 is provided with a periodic material discharging assembly 4222 at the material discharging hole. The periodic material discharging assembly 4222 comprises a material storage barrel 42221 fixedly installed at the bottom end of the guide ring body 4221.

Then, when the powder guide ring 422 rotates following the drive shaft 421, the meshing wheel 42224 rotates continuously under the action of the meshing gear ring 43, thereby achieving periodic matching of the matching hole and the spreading hole, so as to effectively control the stable falling of the metal powder and ensure the effective and uniform progress of the replacement reaction below.

[0064] Reference Fig.10 The pumping auxiliary component 13 includes a guide cone 131, which is conical. The conical setting of the guide cone 131 effectively ensures that when metal precipitation occurs during the treatment process, the metal can be effectively guided to ensure that it falls to the discharge pipe 8 below;

[0065] A vertical pumping channel 132 is provided inside the guide cone 131, and the top of the pumping channel 132 is connected to the spring tube 12. A filter screen 133 is installed at the bottom of the guide cone 131 at the pumping channel 132, so that when the guide cone 131 is in line with the discharge pipe 8 for pumping water, the precipitated metal can be effectively separated to avoid being taken out together.

[0066] Reference Figure 2-Figure 3 as well as Fig.10 The lifting assembly includes a connecting rod 11 connected to a guide cone 131. A vertical through hole is provided on the side of the treatment tank 1 for the connecting rod 11 to move up and down, and a blocking cover 10 for blocking is installed on the outside of the vertical through hole. A starting push rod 9 is installed on the top of the blocking cover 10. The output shaft of the starting push rod 9 penetrates into the interior of the blocking cover 10 and is fixedly connected to one end of the connecting rod 11, thereby effectively controlling the connecting rod 11 to drive the pumping auxiliary assembly 13 to move in the vertical direction, which is convenient for extracting sewage when the sewage level in the treatment tank 1 drops.

[0067] Workflow: In actual use, firstly, electroplating metal wastewater is injected from the liquid inlet pipe 3. During this process, the motor I 41 is started to drive the metal guide assembly 42 to rotate, and the wastewater is injected into the interior of the treatment tank 1 through the liquid inlet pipe 3. During the injection process, the wastewater is screened at the screen 423, so that large particles of impurities in the wastewater can be effectively collected on the surface of the screen 423, and with the help of the setting of the rotating screen 423, the large particles of impurities can evenly fall on the screen 423;

[0068] During the sewage injection process, metal powder with relatively strong metal activity, such as iron, is injected into the powder inlet pipe 5. When the metal powder falls, it falls on the powder guide ring 422. Under the action of the annular guide groove on the guide ring body 4221, the metal powder is always concentrated at the lowest point and falls into the storage barrel 42221. In the process of the periodic unloading component 4222 following the rotation of the powder guide ring 422, the meshing wheel 42224 meshes and rotates with the meshing gear ring 43 to achieve periodic matching of the matching hole and the spreading hole, and the metal powder is evenly sprinkled into the sewage below, so that the metal powder with relatively strong activity reacts with the metal ions in the sewage, so that the heavy metals in the sewage are precipitated and fall into the sedimentation collection and treatment mechanism 2 below for collection;

[0069] When the internal replacement reaction of the sewage is completed, it can be seen that the added metal powder does not react with the water body and eventually settles inside the collection bucket 22, indicating that the metal that can be replaced inside has reacted completely. Then, the water pump 7 is started to extract the treated sewage, and the lifting component is used to lift the pumping auxiliary component 13 until the pumping auxiliary component 13 moves to the upper surface of the precipitated metal. At this time, the internal sewage is completely extracted;

[0070] After the sewage is extracted, the heating tube 25 is energized to increase the temperature of the collection barrel 22, evaporate and dry the water mixed in the metal precipitates, and then start the vibration component to make the resistance cam 26 drive the collection barrel 22 to vibrate up and down. In the case of different densities of metal precipitates, the internal metal precipitates are stratified, and finally the precipitate collection and processing mechanism 2 is removed to realize the stratified collection and processing of metal precipitates.
