Description

Technical Field

[0001] The invention relates to the technical field of waste liquid purification and recovery equipment, in particular to a waste liquid purification and treatment device for copper sulfate preparation. Background Art

[0002] Using waste circuit boards to make copper sulfate is a method of resource recycling, because waste circuit boards contain a certain amount of copper, which can be extracted through a chemical treatment process. The copper sulfate in the copper sulfate waste liquid formed by mixing waste circuit boards with sulfuric acid is extracted, but the remaining waste liquid contains harmful substances, which will not only pollute the environment, but also may pose a potential threat to the ecosystem and human health. Therefore, corresponding purification measures must be taken when treating this type of waste liquid.

[0003] Therefore, based on the actual operation of the existing copper sulfate waste liquid purification and treatment equipment, the waste liquid remaining after extracting copper persulfate still contains recyclable substances and harmful substances. The recyclable substances mainly include metal ions such as iron, zinc and nickel inside the circuit board. These metal ions can be controlled by adding an appropriate amount of sodium hydroxide to control the acidity and alkalinity of the waste liquid, so that the metal ions such as iron, zinc and nickel in the waste liquid are precipitated for easy recycling. Harmful substances include organic materials in the circuit board manufacturing process, such as resins, adhesives, etc., and additive residues, which requires the impurities in the copper sulfate waste liquid to be quickly precipitated through chemical reactions, and the precipitates are step-by-step recovered through different chemical reactions, and the purity of the recovered materials is ensured. At the same time, after the recyclable substances in the copper sulfate waste liquid are recovered, the water in the remaining copper sulfate waste liquid is evaporated and refluxed for use, thereby improving the usability of the copper sulfate waste liquid after recovery and purification. To this end, we propose a waste liquid purification and treatment device for copper sulfate preparation. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a waste liquid purification treatment device for copper sulfate preparation.

[0033] In a typical implementation of the present application, Figure 1-10 As shown, a waste liquid purification treatment device for copper sulfate preparation includes:

[0034] A purification tower 1 is used to contain copper sulfate waste liquid. The purification tower 1 includes a purification shell 4 placed on the ground. A purification barrel 5 is fixedly connected to the inner wall of the purification shell 4. The interior of the purification barrel 5 is filled with copper sulfate waste liquid. A feed pump 6 is fixedly installed on the outside of the purification shell 4. The input end of the feed pump 6 is connected to a bellows 7, and the output end of the feed pump 6 is connected to the interior of the purification barrel 5.

[0035] By setting the above structure, the copper sulfate waste liquid can be sucked into the interior of the purification barrel 5. Specifically, the input end of the bellows 7 is inserted into the interior of the copper sulfate waste liquid. At this time, the feed pump 6 is started, and the copper sulfate waste liquid can be sucked into the interior of the purification barrel 5.

[0036] A stirring mechanism 13 is provided on the top of the purification barrel 5. The stirring mechanism 13 includes an adjusting motor 8 fixedly installed on the top of the purification shell 4. The output end of the adjusting motor 8 is fixedly connected to a stirring shaft 9. The stirring shaft 9 rotates inside the purification barrel 5. The outside of the stirring shaft 9 is fixedly connected to a plurality of upper stirring blades 10, and the plurality of upper stirring blades 10 are arranged in an inclined manner. The outside of the stirring shaft 9 is fixedly connected to a plurality of lower stirring blades 12, and the plurality of lower stirring blades 12 are arranged in an inclined manner. The outside of the stirring shaft 9 is fixedly connected to a plurality of mixing racks 11, and the mixing racks 11 are arranged between the upper stirring blades 10 and the lower stirring blades 12.

[0037] By setting the above structure, the added copper sulfate waste liquid can be stirred to improve the chemical reaction of the copper sulfate waste liquid. Specifically, when the copper sulfate waste liquid needs to be stirred, the regulating motor 8 is started, and the output end of the regulating motor 8 rotates to drive the stirring shaft 9 to rotate, and the stirring shaft 9 rotates to drive the upper stirring blades 10, the mixing frame 11 and the lower stirring blades 12 to rotate. Since the upper stirring blades 10 and the lower stirring blades 12 are all arranged obliquely, the copper sulfate waste liquid will gather toward the mixing frame 11 during the stirring of the copper sulfate waste liquid, and the gathered copper sulfate waste liquid will be dispersed by the mixing frame 11 to achieve sufficient stirring, thereby improving the chemical reaction of the copper sulfate waste liquid.

[0038] A sedimentation valve 31 is provided at the bottom of the purification barrel 5. The sedimentation valve 31 includes an inner shell 23 fixedly connected to the bottom of the purification barrel 5. A plug 24 is slidably connected inside the inner shell 23. A cylinder 25 is fixedly installed at the bottom of the inner wall of the inner shell 23. The extended end of the cylinder 25 is fixedly connected to the bottom of the plug 24. An outer shell 26 is fixedly connected to the bottom of the purification barrel 5. The interior of the outer shell 26 and the exterior of the inner shell 23 form a chamber, which is connected to the purification barrel 5. The bottom of the outer shell 26 is connected to a three-way pipe 27. A three-way valve is provided inside the three-way pipe 27.

[0039] By setting the above structure, the sediment settled at the bottom of the purification barrel 5 can be extracted, which is convenient for collecting the sediment. Specifically, when the copper sulfate waste liquid settles out sediment at the bottom of the purification barrel 5 due to chemical reaction and no new sediment is produced, the cylinder 25 is started at this time, and the output end of the cylinder 25 drives the plug 24 to slide inside the inner shell 23. At this time, due to the hydraulic principle, the sediment at the bottom of the purification barrel 5 and part of the copper sulfate waste liquid flow into the inside of the three-way pipe 27. When the sediment completely flows out of the purification barrel 5, the cylinder 25 is started, and the cylinder 25 moves upward to prevent the copper sulfate waste liquid inside the purification barrel 5 from continuing to flow out;

[0040] It is worth mentioning that, since the top of the plug 24 is arranged in an arc shape, the sediment on the top of the plug 24 and the bottom of the purification barrel 5 will flow into the interior of the three-way pipe 27 along with the flow of the copper sulfate waste liquid, thereby reducing the residual sediment inside the purification barrel 5.

[0041] The regulating mechanism 2 is used to adjust the acidity and alkalinity of the copper sulfate waste liquid in the purification barrel 5 and control the temperature of the copper sulfate, improve and maximize the recovery of the beneficial components in the copper sulfate waste liquid, and the regulating mechanism 2 includes a liquid storage shell 14 fixedly connected to the inner wall of the purification shell 4, and the liquid storage shell 14 is provided with a first regulating chamber 16, a second regulating chamber 17 and a third regulating chamber 18. The first regulating chamber 16 is filled with sodium hydroxide solution, and the second regulating chamber 17 and the third regulating chamber 18 are filled with water. The first regulating chamber 16, the second regulating chamber 17 and the third regulating chamber 18 are filled with water. The inside of the regulating chamber 17 and the third regulating chamber 18 are both provided with a temperature-variable tube 19, the first regulating chamber 16, the second regulating chamber 17 and the third regulating chamber 18 are all connected to the inside of the purification barrel 5, the inside of the liquid storage shell 14 is fixedly connected with a mounting plate 15, and three regulating pumps 20 are fixedly installed on the top of the mounting plate 15, and the input ends of the three regulating pumps 20 are connected with suction pipes 21, which are respectively inserted into the inside of the first regulating chamber 16, the second regulating chamber 17 and the third regulating chamber 18, and the output ends of the three regulating pumps 20 are all connected to the inside of the purification barrel 5;

[0042] By setting the above-mentioned structure, the acidity and alkalinity of the copper sulfate waste liquid inside the purification barrel 5 can be adjusted so that it can produce recyclable precipitates. Specifically, when the acidity and alkalinity of the copper sulfate waste liquid inside the purification barrel 5 need to be adjusted, the regulating pump 20 on the top of the first regulating chamber 16 is started, and the sodium hydroxide solution inside the first regulating chamber 16 is injected into the purification barrel 5 to adjust the acidity and alkalinity of the copper sulfate waste liquid inside the purification barrel 5. When it is necessary to control the temperature of the copper sulfate waste liquid inside the purification barrel 5, when it is necessary to increase the temperature, the regulating pump 20 on the top of the third regulating chamber 18 is started so that the water inside the third regulating chamber 18 is mixed with the copper sulfate waste liquid inside the purification barrel 5 to achieve rapid temperature increase. When it is necessary to cool down, the regulating pump 20 on the top of the second regulating chamber 17 is started so that the water inside the second regulating chamber 17 is mixed with the copper sulfate waste liquid inside the purification barrel 5 to achieve rapid temperature reduction.

[0043] The control mechanism 3 is used to accurately adjust the acidity and alkalinity of the copper sulfate waste liquid to realize the recovery of iron, zinc and nickel in the copper sulfate waste liquid. The control mechanism 3 includes a rotating motor 28 fixedly connected to the bottom of the purification barrel 5, the output end of the rotating motor 28 is fixedly connected to the first reaction barrel 29, the output end of the precipitation valve 31 is connected to the three-way pipe 27, the output end of the bottom of the three-way pipe 27 is arranged on the top of the first reaction barrel 29, the first TDS detector 30 is fixedly installed inside the first reaction barrel 29, the second reaction barrel 32 is fixedly connected inside the purification shell 4, and the bottom of the liquid storage shell 14 is fixedly connected to the regulating pipe 38, and the regulating pipe 38 is connected to the first regulating chamber 16;

[0044] A control shell 45 is fixedly connected to the inner wall of the purification shell 4, and the control shell 45 includes a first control chamber 46 and a second control chamber 47. A first control tube 48 and a second control tube 49 are fixedly connected to one side of the control shell 45. The first control tube 48 is connected to the second control chamber 47, and the first control chamber 46 is connected to the second control tube 49. The output ends of the regulating tube 38, the first control tube 48 and the second control tube 49 are all arranged at the top of the second reaction barrel 32, and a thermometer 36 is fixedly installed at the bottom of the inner wall of the second reaction barrel 32. A stirring motor 35 is fixedly installed on one side of the control shell 45, and a stirring rod 33 is fixedly connected to the output end of the stirring motor 35, and the stirring rod 33 extends to the inside of the second reaction barrel 32. A second TDS detector 34 is installed inside the second reaction barrel 32. The interior of the purification shell 4 is fixedly connected to the inclined shell 22, and one end of the inclined shell 22 extends to the outside of the purification barrel 5. A pH detector is fixedly installed inside the second reaction barrel 32.

[0045] By setting the above structure, the recyclable materials of the copper sulfate waste liquid in the purification barrel 5 can be recycled in a step-by-step manner, and the temperature and pH value required for rapid precipitation can be adjusted according to the different contents of the copper sulfate waste liquid. The copper sulfate waste liquid in the purification barrel 5 can be regulated by a small amount of liquid and precise control. Specifically, the copper sulfate waste liquid in the purification barrel 5 first flows into the first reaction barrel 29 through the precipitation valve 31, and then the rotating motor 28 is started. The output end of the rotating motor 28 rotates to drive the first reaction barrel 29 to rotate. The first reaction barrel 29 rotates to dump the copper sulfate waste liquid inside into the second reaction barrel 32. At this time, the pH value of the copper sulfate waste liquid is detected by the second TDS detector 34. After the detection is completed, the control tube 38 is started to make the sodium hydroxide solution in the first regulating chamber 16 flow into the second reaction barrel 32 to adjust the pH value of the copper sulfate waste liquid in the second reaction barrel 32.

[0046] More specifically, when the pH value of copper sulfate wastewater is adjusted to the dischargeable standard, the pH value should be between 6 and 9, and at the same time:

[0047] Iron ions begin to precipitate at a pH between 3 and 4, forming iron hydroxide precipitates;

[0048] Zinc ions begin to precipitate at a pH between 8 and 9, forming zinc hydroxide precipitate;

[0049] Nickel ions begin to precipitate when the pH value exceeds 8.5, forming nickel hydroxide precipitate;

[0050] By gradually adjusting the pH value of the copper sulfate waste liquid, the recyclable precipitates in the copper sulfate waste liquid can be efficiently recovered in a step-by-step manner;

[0051] After the pH of the copper sulfate waste liquid is adjusted, the first control tube 48 can be opened to allow the high-temperature liquid in the second control chamber 47 to flow into the second reaction barrel 32 to heat the copper sulfate waste liquid in the second reaction barrel 32. The second control tube 49 can also be opened to allow the low-temperature liquid in the first control chamber 46 to flow into the second reaction barrel 32 to cool the copper sulfate waste liquid in the second reaction barrel 32. When the pH of the copper sulfate waste liquid is adjusted and the temperature is increased or decreased, the second TDS detector 34 is used to detect the amount of sediment in the copper sulfate waste liquid so as to detect the optimal temperature and pH value for degrading the sediment of the copper sulfate waste liquid. The liquids in the first regulating chamber 16, the second regulating chamber 17 and the third regulating chamber 18 are introduced into the purification barrel 5 through three regulating pumps 20 in proportion to the detected temperature and pH value, so as to quickly adjust the copper sulfate waste liquid in the purification barrel 5.

[0052] It is worth mentioning that the water inside the second regulating chamber 17 is cooler than the water inside the first control chamber 46, and the water inside the third regulating chamber 18 is hotter than the water inside the second control chamber 47. In this way, when adjusting the copper sulfate waste liquid inside the second reaction barrel 32, rapid and accurate adjustment can be achieved by adding a large amount of water. The adjusted value can be adjusted by a small amount of liquid through a heat balance formula to adjust the copper sulfate waste liquid inside the purification barrel 5, which is convenient for the purification of the copper sulfate waste liquid in the later stage.

[0053] Heat balance formula: m1cΔT1=m2cΔT2, m1 is the mass of the initial water, m2 is the mass of the hot water poured in, c is the specific heat capacity of water, which is usually fixed at about 4.18 kJ / (kg·K), ΔT1 and ΔT2: represent the temperature changes of the initial water and the poured hot water, respectively. ΔT1 is the difference between the target temperature T2 and the initial temperature T1, i.e. ΔT1= T2-T1; and ΔT2 is the difference between the initial temperature T3 of the poured hot water and the final equilibrium temperature T2, i.e. ΔT2=T3-T2;

[0054] Substituting into the heat balance formula m1cΔT1=m2cΔT2, we can solve for m2. Specifically:

[0055] , since the specific heat capacity c can be negated on both sides, the formula is simplified to:

[0056] , so we can solve for m2, , it is possible to use a small amount of liquid to accurately adjust the copper sulfate waste liquid inside the purification barrel 5.

[0057] Preferably, a spray pipe 50 is fixedly connected to the bottom of the liquid storage shell 14, the spray pipe 50 is connected to the second regulating chamber 17, a plurality of nozzles are opened at the output end of the spray pipe 50, and a hose 37 is connected to the bottom of the second reaction barrel 32, and the output end of the hose 37 is connected to the bottom of the first reaction barrel 29.

[0058] By setting the above-mentioned structure, the precipitate inside the first reaction barrel 29 can be collected, and it is ensured that there is no other precipitate in the first reaction barrel 29 after dumping, thereby improving the purity of the recovered material in the copper sulfate waste liquid and facilitating the later utilization. Specifically, after the copper sulfate waste liquid that has not undergone chemical reaction in the first reaction barrel 29 is dumped, the rotating motor 28 is started in reverse, and the rotating motor 28 rotates to drive the first reaction barrel 29 to rotate in the opposite direction, so that the pouring port of the first reaction barrel 29 cooperates with the top of the inclined shell 22. At this time, the spray pipe 50 is started, and the water in the second regulating chamber 17 sprays the interior of the first reaction barrel 29, sprays out the precipitate inside the first reaction barrel 29, and collects it through the inclined shell 22, while ensuring the purity of the precipitate recovered each time.

[0059] Preferably, heat exchangers are provided inside the second control chamber 47 and the first control chamber 46 , and temperature sensors are provided inside the first regulating chamber 16 , the second regulating chamber 17 , the third regulating chamber 18 , the first control chamber 46 , and the second control chamber 47 .

[0060] By setting up the above-mentioned structure, the temperature of the water inside the second control chamber 47 and the first control chamber 46 can be accurately regulated, and at the same time, the temperature inside the first regulating chamber 16, the second regulating chamber 17, the third regulating chamber 18, the first control chamber 46 and the second control chamber 47 can be accurately controlled, thereby improving the chemical reaction accuracy of the copper sulfate waste liquid.

[0061] A wastewater shell 39 is fixedly connected to the inner wall of the purification barrel 5, and a wastewater pipe 40 is connected to the bottom of the wastewater shell 39. The other end of the three-way pipe 27 is connected to the wastewater shell 39. An evaporation and condensation device 41 is fixedly installed on the inner wall of the purification barrel 5, and the evaporation and condensation device 41 is connected to the wastewater shell 39. A collection shell 42 is fixedly connected to the inner wall of the purification barrel 5, and the collection shell 42 is connected to the evaporation and condensation device 41.

[0062] By setting the above-mentioned structure, the copper sulfate waste liquid after the recyclables are removed can be finally purified. Specifically, after all the recyclables in the copper sulfate waste liquid are recovered, the remaining copper sulfate waste liquid enters the interior of the wastewater shell 39 through the three-way pipe 27, and is evaporated and distilled by the evaporation and condensation equipment 41, so that the amount of copper sulfate waste liquid in the wastewater shell 39 is gradually reduced, and harmful substances in the copper sulfate waste liquid are gathered. When the copper sulfate waste liquid is reduced to a certain amount, the concentrated copper sulfate waste liquid can be discharged through the wastewater pipe 40 for separate treatment, and the copper sulfate waste liquid distilled and condensed by the evaporation and condensation equipment 41 can flow into the interior of the collection shell 42 for recovery and storage, thereby realizing the recovery and purification of the copper sulfate waste liquid.

[0063] The collecting shell 42 is connected to the second regulating chamber 17 and the third regulating chamber 18 , the collecting shell 42 is connected to a replenishing pipe 44 , the second control chamber 47 and the first control chamber 46 are connected to the replenishing pipe 44 , and the bottom of the collecting shell 42 is connected to a water outlet pipe 43 .

[0064] By setting the above-mentioned structure, the copper sulfate waste liquid can be purified and recycled. Specifically, the purified copper sulfate waste liquid inside the collecting shell 42 can be directly supplied to the water inside the second control chamber 47 and the first control chamber 46 through the replenishing pipe 44, and can also be directly supplied to the second regulating chamber 17 and the third regulating chamber 18, so as to achieve true purification and recycling. When the collecting shell 42 is full, it can be released through the water outlet pipe 43.

[0065] The working principle of the present invention is as follows: the input end of the bellows 7 is inserted into the interior of the copper sulfate waste liquid, and the feed pump 6 is started at this time, so that the copper sulfate waste liquid can be sucked into the interior of the purification barrel 5;

[0066] When the copper sulfate waste liquid needs to be stirred, the regulating motor 8 is started at this time, and the output end of the regulating motor 8 rotates to drive the stirring shaft 9 to rotate, and the stirring shaft 9 rotates to drive a plurality of upper stirring blades 10, a mixing frame 11 and a lower stirring blade 12 to rotate. Since the upper stirring blade 10 and the lower stirring blade 12 are arranged obliquely, the copper sulfate waste liquid will gather toward the mixing frame 11 during the stirring of the copper sulfate waste liquid, and the copper sulfate waste liquid gathered by the mixing frame 11 is dispersed to achieve sufficient stirring, thereby improving the chemical reaction of the copper sulfate waste liquid;

[0067] The copper sulfate waste liquid in the purification barrel 5 first flows into the first reaction barrel 29 through the sedimentation valve 31, and then the rotating motor 28 is started. The output end of the rotating motor 28 rotates to drive the first reaction barrel 29 to rotate. The first reaction barrel 29 rotates to pour the copper sulfate waste liquid inside into the second reaction barrel 32. At this time, the pH value of the copper sulfate waste liquid is detected by the second TDS detector 34. After the detection is completed, the control tube 38 is started to make the sodium hydroxide solution in the first regulating chamber 16 flow into the second reaction barrel 32 to adjust the pH value of the copper sulfate waste liquid in the second reaction barrel 32;

[0068] After the pH of the copper sulfate waste liquid is adjusted, the first control tube 48 can be opened to allow the high-temperature liquid in the second control chamber 47 to flow into the second reaction barrel 32 to heat the copper sulfate waste liquid in the second reaction barrel 32. The second control tube 49 can also be opened to allow the low-temperature liquid in the first control chamber 46 to flow into the second reaction barrel 32 to cool the copper sulfate waste liquid in the second reaction barrel 32. When the pH of the copper sulfate waste liquid is adjusted and the temperature is increased or decreased, the second TDS detector 34 is used to detect the amount of sediment in the copper sulfate waste liquid, so as to detect the optimal temperature and pH value for the copper sulfate waste liquid to degrade the sediment. The liquids in the first regulating chamber 16, the second regulating chamber 17 and the third regulating chamber 18 are introduced into the purification barrel 5 through three regulating pumps 20 in proportion to the detected temperature and pH value, so as to quickly adjust the copper sulfate waste liquid in the purification barrel 5.

[0069] When it is necessary to adjust the acidity and alkalinity of the copper sulfate waste liquid in the purification barrel 5, the regulating pump 20 at the top of the first regulating chamber 16 is started, and the sodium hydroxide solution in the first regulating chamber 16 is injected into the purification barrel 5 to adjust the acidity and alkalinity of the copper sulfate waste liquid in the purification barrel 5. When it is necessary to control the temperature of the copper sulfate waste liquid in the purification barrel 5, when it is necessary to increase the temperature, the regulating pump 20 at the top of the third regulating chamber 18 is started to mix the water in the third regulating chamber 18 with the copper sulfate waste liquid in the purification barrel 5 to achieve rapid temperature increase. When it is necessary to cool down, the regulating pump 20 at the top of the second regulating chamber 17 is started to mix the water in the second regulating chamber 17 with the copper sulfate waste liquid in the purification barrel 5 to achieve rapid temperature reduction.

[0070] After the copper sulfate waste liquid that has not undergone chemical reaction in the first reaction barrel 29 is dumped, the rotating motor 28 is started in reverse, and the rotating motor 28 drives the first reaction barrel 29 to rotate in reverse, so that the dumping port of the first reaction barrel 29 is matched with the top of the inclined shell 22. At this time, the spray pipe 50 is started, and the water in the second regulating chamber 17 sprays the inside of the first reaction barrel 29, sprays out the precipitate in the first reaction barrel 29, and collects it through the inclined shell 22, while ensuring the purity of the precipitate recovered each time;

[0071] After all the recyclable materials in the copper sulfate waste liquid are recovered, the remaining copper sulfate waste liquid enters the interior of the wastewater shell 39 through the three-way pipe 27, and is evaporated and distilled by the evaporation condensation device 41, so that the amount of copper sulfate waste liquid in the wastewater shell 39 is gradually reduced, and harmful substances in the copper sulfate waste liquid are gathered. When the copper sulfate waste liquid is reduced to a certain amount, the concentrated copper sulfate waste liquid can be discharged through the wastewater pipe 40 for separate treatment, and the copper sulfate waste liquid distilled and condensed by the evaporation condensation device 41 can flow into the interior of the collection shell 42 for recycling and storage, so as to achieve the recovery and purification of the copper sulfate waste liquid;

[0072] The purified copper sulfate waste liquid inside the collecting shell 42 can be directly supplied to the water inside the second control chamber 47 and the first control chamber 46 through the replenishing pipe 44, and can also be directly supplied to the second regulating chamber 17 and the third regulating chamber 18, so as to realize true purification and recycling. When the collecting shell 42 is full, it can be released through the water outlet pipe 43.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
