Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, in particular to a copper sulfate production wastewater treatment device. Background Art

[0002] Copper sulfate production wastewater is a kind of industrial wastewater containing high concentrations of copper ions and sulfate ions. It mainly contains copper ions and sulfate ions. Due to the presence of copper ions, the wastewater usually appears blue or green.

[0003] In the current existing technology, copper sulfate wastewater contains a large amount of heavy metal ions, and the wastewater discharge needs to treat the heavy metal ions. The methods for treating copper ions in copper sulfate wastewater include chemical precipitation, ion exchange, electrolytic deposition, and membrane separation technology. The electrolytic deposition method reduces the copper ions in the wastewater into metallic copper through electrolysis and deposits them on the cathode. During the treatment, the copper sulfate wastewater is injected into an electrolytic cell, in which an anode plate and a cathode plate are installed. Direct current is passed for electrolysis, and the metallic copper undergoes a reduction reaction at the cathode and forms deposited copper on the cathode plate to remove the heavy metal ions in the sulfate wastewater.

[0004] However, during use, the surface of the cathode plate continuously reduces deposited copper, and the thickness of the deposited copper continues to increase. When the thickness of the deposited copper is too thick, it will affect the copper deposition rate. Therefore, a copper sulfate production wastewater treatment device is proposed to address the above problem. Summary of the invention

DETAILED DESCRIPTION

[0028] 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.

[0029] Specific examples are given below.

[0030] See also Figure 1-4As shown, a copper sulfate production wastewater treatment device includes an electrolytic cell 11, an anode plate 18 and a cathode plate 16, wherein a plurality of the anode plates 18 are installed inside the electrolytic cell 11, and an opening is provided at the top of the electrolytic cell 11; a frame 12 is fixedly connected above the electrolytic cell 11, and a multi-section hydraulic cylinder 13 is fixedly connected to the frame 12; a cross frame 14 is fixedly connected to the output end of the multi-section hydraulic cylinder 13, and a plurality of brackets 15 are fixedly connected to the bottom of the cross frame 14, wherein the anode plate 18 is detachably installed on the bracket 15, and the multi-section hydraulic cylinder 13 can drive the cathode plate 16 to move, so that the cathode plate 16 is inserted into or pulled out of the electrolytic cell 11;

[0031] Bases 19 are fixedly connected to both sides of the opening, and scraping frames 191 are hingedly connected to the two bases 19. The cathode plate 16 is located between the two scraping frames 191. A scraper 192 for scraping the deposited copper on the cathode plate 16 is provided on the top of the scraping frame 191. A return spring is fixedly connected between the scraping frame 191 and the base 19.

[0032] When in use, the cathode plate 16 can be driven to move by means of the multi-section hydraulic cylinder 13, so that the cathode plate 16 is inserted into the electrolytic cell 11 or pulled out from the electrolytic cell 11. In the process of pulling out the cathode plate 16 upward, the cathode plate 16 is pulled out from between the two scraper frames 191, and because the surface of the cathode plate 16 is covered with deposited copper, the scraper frames on both sides are rotated and opened, which is convenient for pulling out the cathode plate 16. When the multi-section hydraulic cylinder 13 inserts the cathode plate 16 into the electrolytic cell 11, the reset spring drives the scraper frame 191 to reset, and then the cathode plate 16 moves downward from between the two scrapers, and the scraper 192 slides between the deposited copper and the cathode plate 16 to peel off the deposited copper from the cathode plate 16. In this way, the deposited copper can be peeled off regularly, and the thickness of the deposited copper on the cathode plate 16 can be controlled, thereby reducing the influence of the excessive thickness of the deposited copper on the deposition rate.

[0033] Further, such as Figure 2 and 7As shown, a limiting seat 21 is fixedly connected to the inner wall of the bottom of the electrolytic cell 11, and a groove 22 is opened inside the limiting seat 21; the size of the groove 22 matches the bottom of the cathode plate 16, and the cathode plate 16 can slide downward and be inserted into the groove 22; when in use, the deposited copper will completely cover the cathode plate 16 due to natural deposition, and the scraper 192 will scrape it off at this time, and the deposited copper covering the bottom of the cathode plate 16 needs to be cut first, and then it can be inserted between the deposited copper and the cathode plate 16. In this embodiment, when the cathode plate 16 is inserted, the bottom of the cathode plate 16 will be inserted into the groove 22 of the limiting seat 21. The limiting seat 21 is made of engineering plastic or ceramic material. The limiting seat 21 is used to limit the shape of the deposited copper formed at the bottom of the cathode plate 16, so that the bottom of the cathode plate 16 is exposed, so as to facilitate subsequent peeling, and can reduce the force exerted on the cathode plate 16 by forcibly cutting the deposited copper, thereby reducing the deformation and damage of the cathode plate 16.

[0034] Further, such as Figure 2 and 5 -6, the frame 12 is fixedly connected with an electric slide rail 31, and a plurality of supports 32 are installed on the electric slide rail 31. The electric slide rail 31 can drive the supports 32 to move, and the supports 32 are rotatably connected with straight rollers 33, and the cathode plate 16 can pass between two straight rollers 33 close to each other. The supports 32 are fixedly connected with a motor 34, and the motor 34 can drive the straight rollers 33 to rotate through a belt drive, and a plurality of tooth plates 35 are arranged on the straight rollers 33; when it is necessary to scrape off the deposited copper, the support 32 is controlled to move by the electric slide rail 31, and the support rollers on the support 32 move to the two sides of the cathode plate 16, and then the motor 34 is started, and the motor 34 drives the straight rollers 33 to rotate, thereby making the tooth plates 35 strikes the deposited copper formed on the bottom of the cathode plate 16, so that the deposited copper on the bottom is subjected to force and peeled off from the cathode plate 16 to form a gap, so that the scraper 192 can be directly inserted into the gap between the deposited copper and the cathode plate 16 to facilitate peeling. If scraping is performed directly by the scraper 192, it is required that the scraper 192 fits tightly against the cathode plate 16 so that the deposited copper at the bottom of the cathode plate 16 can be pushed open to form a gap, and the fitting accuracy of the scraper 192 is too high. The tooth plate 35 and the straight roller 33 are connected in a fixed manner, which can facilitate the striking and separation of the deposited copper. In another embodiment, the tooth plate 35 is hinged to the straight roller 33, and it relies on centrifugal force to open and strike the straight roller 33. The tooth plate 35 can continuously strike the deposited copper.

[0035] Further, such as Figure 6As shown, an avoidance groove is provided on the straight roller 33, and the tooth plate 35 is rotatably connected to the side wall of the avoidance groove, and a screw barrel 41 is fixedly connected to the tooth plate 35, and an adjusting bolt 42 is threadedly connected to the middle part of the screw barrel 41, and a spring seat is rotatably connected to the end of the adjusting bolt 42, and a first spring 43 is fixedly connected between the spring seat and the side wall of the avoidance groove, and the tightness of the first spring 43 can be adjusted by rotating the adjusting spring; when in use, the tooth plate 35 is hinged to the straight roller 33, and the tooth plate 35 can continuously strike the deposited copper, and then the tooth plate 35 can be supported to open by relying on the first spring 43, and when the striking force is too large, the tooth plate 35 will overcome the elastic force of the first spring 43, and before use, the staff can rotate the adjusting bolt 42 according to the situation to adjust the tightness of the first spring 43, so as to reduce the situation where the tooth plate 35 is stuck, and reduce the situation where the bottom of the deposited copper is deformed and broken due to excessive force of the tooth plate 35.

[0036] Further, such as Figure 3-4 As shown, the inner wall of the scraper frame 191 is fixedly connected with a baffle, and the side of the scraper frame 191 is fixedly connected with a fixed seat 51. A roller seat 52 is arranged in the fixed seat 51, and a pressure roller 53 is rotatably connected to the roller seat 52. The pressure roller 53 is located on the side of the baffle, and the deposited copper under scraping passes between the baffle and the pressure roller 53, and the pressure roller 53 limits the bending of the deposited copper; when in use, the deposited copper under scraping moves along the baffle, and then passes between the baffle and the pressure roller 53, and the pressure roller 53 limits the bending of the deposited copper. Due to the large amount of impurities in the wastewater, it is difficult to ensure the uniformity of the thickness of the metal deposited on the cathode plate 16 and the uniformity of the distribution of material properties. The deposited copper will break during scraping, and then the gap formed between the deposited copper and the cathode plate 16 will disappear. Relying on the above-mentioned setting, the bending angle of the deposited copper scraped off from the cathode plate 16 can be limited, thereby reducing the random curling due to natural scraping, which causes the curling angle to be too large and break, so as to facilitate continuous scraping and scraping of deposited copper.

[0037] Further, such as Figure 3-4 As shown, two roller seats 52 are provided, and a slide groove 62 is opened on the fixed seat 51 at a position corresponding to the roller seat 52, and the two ends of the roller seat 52 are respectively inserted into the corresponding slide groove 62 and slidably connected thereto, and a support rod 61 is fixedly connected in the slide groove 62, and the support rod 61 passes through the slide groove 62 and is slidably connected thereto, and a second spring is fixedly connected between the roller seat 52 and the side wall of the slide groove 62; when in use, due to the large amount of impurities in the copper sulfate wastewater, the thickness uniformity of the deposition cylinder is poor, and by providing the slide groove 62, the roller seat 52 can slide in the slide groove 62 and on the support rod 61, and it is supported by the second spring, so that the pressure roller 53 can move within a certain range, so as to adapt to deposited copper of different thicknesses and improve applicability.

[0038] Further, such as Figure 3-4As shown, the sides of the two fixed seats 51 are fixedly connected with a cylinder 71, and the output end of the cylinder 71 is fixedly connected with a cutter 72 for cutting off the scraped deposited copper, and the cutter 72 is located on the side of the pressure roller 53; the cutter 72 is located between the two roller seats 52; when in use, when the scraped deposited copper is connected into one piece, it will increase the gravity, causing the deposited copper to break at the scraping place of the cutter 72, affecting the scraping effect, and at the same time, there will be a situation where a large piece of deposited copper falls off and hits the scraping for a moment. The cylinder 71 can push the cutter 72 to move, thereby driving the cutter 72. The movement of the cutter 72 can cut off the deposited copper and divide the scraped deposit into multiple pieces, thereby reducing the weight.

[0039] Further, such as Figure 2 and 7 As shown, a plurality of guide seats 82 are fixedly connected to the bracket 15, and a guide rod 81 is fixedly connected between the frame 12 and the bottom side of the electrolytic cell 11, and the guide rod 81 passes through the guide seat 82 and is slidably connected thereto, and the guide seat 82 can slide up and down along the guide rod 81; when in use, a plurality of guide seats 82 are fixedly connected to the bracket 15, and then the guide seat 82 slides up and down on the guide rod 81, so as to guide the movement of the guide seat 82, and then guide the bracket 15 and the cathode plate 16, thereby improving the stability of their movement, and thereby reducing the shaking and scratching of the cathode plate 16.

[0040] Further, such as Figure 4 As shown, a push rod 92 is fixedly connected to the side of the scraper 192, and the push rod 92 passes through the scraper frame 191 and is slidably connected thereto. A third spring 93 is fixedly connected between the scraper 192 and the scraper frame 191. Both sides of the scraper 192 are rotatably connected to pulleys 91. When scraping the deposited copper, the pulley 91 rolls on the surface of the cathode plate 16, and the gap between the scraper 192 and the cathode plate 16 is 2-15mm; when scraping the deposited copper, the pulley 91 fits the surface of the cathode plate 16, and the pulley 91 is slightly convex. The cathode plate 16 is provided so that there is a gap of 2-15mm between the scraper 192 and the cathode plate 16, so as to reduce the situation that the scraper 192 directly contacts and rubs against the cathode plate 16, causing the surface of the cathode plate 16 to be scratched, and reduce the problem of increased roughness due to friction, which in turn increases the difficulty of stripping the deposited copper, and reduces the problem of bending or processing tolerance due to long-term use, and the problem of convex or concave on the cathode plate 16. The third spring 93 is used to play the role of the pulley 91 in contacting the cathode plate 16, thereby improving the scope of application.

[0041] Further, such as Figure 7As shown, bevels 10 are provided on both sides of the top of the limiting seat 21; the bevels 10 are located on both sides of the groove 22; when in use, relying on the bevel 10 on the top of the limiting seat 21, the deposited copper deposited at the bottom of the cathode plate 16 can have a bevel 10, so it is convenient for the scraper 192 to scrape it off, and it is convenient for the tooth plate 35 to hit, so that the deposited copper at the bottom is separated from the cathode plate 16.

[0042] Working principle: when in use, the cathode plate 16 can be driven to move by the multi-section hydraulic cylinder 13, so that the cathode plate 16 is inserted into the electrolytic cell 11 or pulled out from the electrolytic cell 11. In the process of pulling out the cathode plate 16 upward, the cathode plate 16 is pulled out from between the two scraper racks 191, and because the surface of the cathode plate 16 is covered with deposited copper, it will cause the scraper racks on both sides to rotate and open, so as to facilitate the extraction of the cathode plate 16. When the multi-section hydraulic cylinder 13 inserts the cathode plate 16 into the electrolytic cell 11, the reset spring drives the scraper rack 191 to reset, and then the cathode plate 16 moves downward from between the two scrapers, and the scraper 192 slides between the deposited copper and the cathode plate 16, so that the deposited copper is peeled off from the cathode plate 16, so that the deposited copper can be peeled off regularly, and the thickness of the deposited copper on the cathode plate 16 can be controlled, thereby reducing the influence of the excessive thickness of the deposited copper on the deposition rate;

[0043] The deposited copper will completely cover the cathode plate 16 when it is naturally deposited. At this time, the scraper 192 needs to scrape it. It is necessary to cut the deposited copper covering the bottom of the cathode plate 16 first, and then insert it between the deposited copper and the cathode plate 16. In this embodiment, when inserting the cathode plate 16, the bottom of the cathode plate 16 will be inserted into the groove 22 of the limiting seat 21. The limiting seat 21 is made of engineering plastic or ceramic material. The limiting seat 21 is used to limit the shape of the deposited copper formed at the bottom of the cathode plate 16, so that the bottom of the cathode plate 16 is exposed, which can facilitate subsequent peeling and reduce the force applied to the cathode plate 16 by forcibly cutting the deposited copper, thereby reducing the deformation and damage of the cathode plate 16. Relying on the inclined surface 10 on the top of the limiting seat 21, the deposited copper deposited on the bottom of the cathode plate 16 can have the inclined surface 10, so that it is convenient for the scraper 192 to scrape it, and it is convenient for the tooth plate 35 to hit, so that the deposited copper at the bottom is separated from the cathode plate 16;

[0044] When it is necessary to scrape off the deposited copper, the electric slide 31 is used to control the movement of the support 32, and the support rollers on the support 32 move to the two sides of the cathode plate 16, and then the motor 34 is started. The motor 34 drives the straight roller 33 to rotate, so that the tooth plate 35 hits the deposited copper formed on the bottom of the cathode plate 16, so that the deposited copper at the bottom is forced to peel off from the cathode plate 16 to form a gap, so that the scraper 192 can be directly inserted into the gap between the deposited copper and the cathode plate 16 to facilitate peeling. If scraping is performed directly by the scraper 192, it is necessary for the scraper 192 to fit tightly against the cathode plate 16, so that the deposited copper at the bottom of the cathode plate 16 can be pushed open to form a gap, and the fitting accuracy of the scraper 192 is too high. The connection mode is fixed connection, which can facilitate the separation of the deposited copper by striking. In another embodiment, the tooth plate 35 is hinged with the straight roller 33, which relies on centrifugal force to open and strike the straight roller 33, and the tooth plate 35 can continuously strike the deposited copper. The tooth plate 35 is hinged with the straight roller 33, and the tooth plate 35 can continuously strike the deposited copper. Then, the tooth plate 35 can be supported to open by the first spring 43. When the striking force is too large, the tooth plate 35 will overcome the elastic force of the first spring 43. Before use, the staff rotates the adjustment bolt 42 according to the situation to adjust the tightness of the first spring 43, so as to reduce the situation that the tooth plate 35 is stuck, and reduce the situation that the bottom of the deposited copper is deformed and broken due to excessive force of the tooth plate 35;

[0045] When in use, the deposited copper under scraping moves along the baffle plate, and then passes through between the baffle plate and the pressure roller 53. The pressure roller 53 limits the bending of the deposited copper. Due to the large amount of impurities in the wastewater, it is difficult to ensure the uniformity of the thickness of the metal deposited on the cathode plate 16 and the uniformity of the distribution of material properties. The deposited copper will break during scraping, which will cause the gap formed between the deposited copper and the cathode plate 16 to disappear. Relying on the above-mentioned setting, the bending angle of the deposited copper scraped off from the cathode plate 16 can be limited, thereby reducing the random curling of natural scraping, which causes the situation of breaking due to excessive curling angle, facilitating continuous scraping and scraping of the deposited copper. Due to the large amount of impurities in the copper sulfate wastewater, the thickness uniformity of the deposition tube is poor. By setting the slide groove 62, the roller seat 52 can slide in the slide groove 62 and on the support rod 61, and it is supported by the second spring, so that the pressure roller 53 can move within a certain range, so as to adapt to deposited copper of different thicknesses and improve applicability.

[0046] When the scraped deposited copper is connected into one piece, it will increase the gravity, causing the deposited copper to break at the scraping place of the cutter 72, affecting the scraping effect. At the same time, a large piece of deposited copper will fall off and hit the scraper in an instant. The cylinder 71 can push the cutter 72 to move, thereby driving the cutter 72. The movement of the cutter 72 can cut off the deposited copper and divide the scraped deposit into multiple pieces, thereby reducing the weight.

[0047] By fixing a plurality of guide seats 82 on the bracket 15, the guide seats 82 slide up and down on the guide rod 81, so as to guide the movement of the guide seats 82, and then guide the bracket 15 and the cathode plate 16, thereby improving the stability of their movement, and thus reducing the situation where the cathode plate 16 shakes and is scratched;

[0048] When scraping off the deposited copper, the pulley 91 fits against the surface of the cathode plate 16, and the pulley 91 slightly protrudes from the cathode plate 16, which allows a gap of 2-15mm between the scraper 192 and the cathode plate 16, thereby reducing the situation where the scraper 192 directly fits and rubs against the cathode plate 16, causing scratches on the surface of the cathode plate 16, and reducing the problem of increased roughness due to friction, which in turn increases the difficulty in stripping the deposited copper, and reduces the problem of bending or processing tolerances due to long-term use, and the problem of convexity or concaveness on the cathode plate 16. The third spring 93 is used to make the pulley 91 fit the cathode plate 16, thereby increasing the scope of application.
