Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to electroplating wastewater treatment equipment. Background Technology

[0002] Electroplating wastewater generally originates from: cleaning water from plated parts, waste electroplating solutions, and other wastewater, including water used for rinsing workshop floors, washing plates, condensate from ventilation equipment, and cooling water from leaks in the plating tanks. This cooling water remains uncontaminated during use except for temperature increases. The quality and quantity of electroplating wastewater are related to factors such as the electroplating process conditions, production load, operation management, and water usage. Electroplating wastewater is complex and its composition is difficult to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, and silver, as well as cyanides. Some of these are highly toxic substances that are carcinogenic, teratogenic, and mutagenic. Therefore, specialized electroplating wastewater treatment equipment is required for its treatment.

[0003] Electroplating wastewater treatment requires multiple stages, especially the addition of alkali and aeration in the equalization tank. During the treatment process, alkali blocks need to be manually placed into the equalization tank, and then the stirring device is started to quickly mix the large alkali blocks with the wastewater. However, this treatment process not only fails to reduce the labor intensity of the workers, but also increases the auxiliary equipment, thus leading to an increase in the cost of electroplating wastewater treatment.

The straight pipe is connected through the flow space formed by the top plate and bottom plate.

[0008] Preferably, both the top plate and the bottom plate are provided with sliding rods, the top plate and the bottom plate are arranged horizontally, the sliding rods on the top plate and the bottom plate are arranged parallel to each other, and the straight pipe corresponding to the sliding rod is provided with a support.

[0011] Preferably, a crossbar is slidably connected to the rack, the crossbars are respectively located at the connection of the rack, the crossbars on both sides are arranged parallel to each other, the crossbar is fixedly connected to the third fixed seat, and a return spring is sleeved on the crossbar, the return spring is located between the third fixed seat and the rack, and one end of the return spring is hooked on the rack.

[0012] Preferably, a swing frame is provided at the other end of the movable rod, the swing frame is located on both sides of the movable rod, the swing frame is arranged in a straight line, and the swing frame and the movable rod are arranged in a T-shape.

[0013] Preferably, both the top plate and the bottom plate are provided with vertical seats, which are arranged vertically on the top plate and the bottom plate respectively.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: This electroplating wastewater treatment equipment utilizes a rotating rod installed within an equalization tank. A dial wheel is mounted on the rotating rod, and when the motor controls the rotation of the rod, the dial wheel also rotates. Part of the dial wheel is inside the electroplating wastewater, while the other part is outside. When a scoop plate is installed on the side edge of the dial wheel, the scoop plate and the dial wheel form a scoop shape. As the dial wheel rotates, it scoops up the electroplating wastewater at the scoop plate location, thus achieving aeration. A reagent tank is installed on the equalization tank. Alkali blocks inside the reagent tank can enter between the top and bottom plates through curved and straight pipes. Because the straight pipes are arranged at an angle, the alkali blocks can be directed towards... The top and bottom plates roll together to allow the reagent to flow. When the alkali block enters between the top and bottom plates, the plates move in an alternating manner. Both the top and bottom plates have protrusions that are staggered. When the alkali block enters between the top and bottom plates, it is broken up by the action of the plates, thus breaking it into smaller pieces. These pieces then fall onto the guide frame and eventually slide into the electroplating wastewater, where they mix with the wastewater. The entire process can be automated, reducing the labor intensity of workers and lowering processing costs.

[0016] This electroplating wastewater treatment equipment, by installing a first fixed base, a second fixed base, and a third fixed base on a base platform, allows a movable frame to be installed on the first fixed base. The movable frame's rollers are located in the rotation direction of a dial wheel, which drives a dial plate to rotate. When the dial plate rotates to the movable frame's position, it pushes the movable frame, allowing it to move on the first fixed base. This, in turn, drives a gear to move horizontally. A rack meshes with the gear, driving it to rotate. The gear is mounted on a movable rod, which is fixed to a second fixed base. The other end of the movable rod... One side is connected to a swing frame, and the insert rod on the swing frame is inserted into the vertical groove of the vertical seat. The vertical seat is installed on the top plate and the bottom plate respectively. When the movable rod rotates, the upper and lower swing frames will move in two directions. When the swing frame is connected to the vertical seat through the insert rod, the swing frame can drive the vertical seat to move, and the top plate and the bottom plate can move in opposite directions. When the alkali block enters between the top plate and the bottom plate, it can be crushed by the protrusion, thus ensuring that the alkali block can be crushed into small particles. This ensures that the alkali block can quickly mix with the wastewater when it enters the wastewater, so that there is no need to install a separate stirring device, thereby reducing the treatment cost.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 8As shown, the electroplating wastewater treatment equipment provided by the present invention includes an equalization tank 1, an inlet pipe 2, and an outlet pipe 4. A base platform 9 is provided on the equalization tank 1, and a reagent tank 5 is provided on the base platform 9. A top plate 14 and a bottom plate 12 are provided at the output port of the reagent tank 5. Protrusions 13 are provided on the opposite end faces of the top plate 14 and the bottom plate 12, and the protrusions 13 on the top plate 14 and the bottom plate 12 are arranged alternately. A swing frame 27 is connected to the top plate 14 and the bottom plate 12 respectively. The swing frame 27 is located on the side edge of a movable rod 26. The movable rod 26 is rotatably connected to a second fixed seat 20 on the base platform 9. The input end of the movable rod 26 is connected to a movable frame 17. A roller 18 is provided on the movable frame 17. The movable frame 17 is located in the rotation direction of a dial wheel 3. The dial wheel 3 is located on a rotating rod 7 inside the equalization tank 1. A lever 6 is installed on the side edge of the 3. Alkali blocks are pre-placed in the reagent tank 5. When treating electroplating wastewater, the rotating rod 7 is controlled to rotate, and the lever 3 will drive the lever 6 to rotate, so that the wastewater can be lifted and aerated. During the rotation of the lever 3, the lever 6 will move to the position of the moving frame 17, thereby squeezing the moving frame 17 to make it move. The moving frame 17 will move on the first fixed seat 19. A rack 25 is installed on the moving frame 17, which can drive the gear 21 to rotate. The movable rod 26 on the gear 21 will drive the swing frame 27 to move, thereby realizing the movement of the top plate 14 and the bottom plate 12, thereby breaking the passing alkali blocks into small pieces, which are then discharged into the wastewater and quickly mixed with the wastewater. By setting it up, automation can be achieved, reducing the labor intensity of the staff and reducing the treatment cost.

[0028] The base platform 9 is inclined, with its bottom end facing the regulating tank 1. A guide frame 8 is installed on the base platform 9, which is arranged along the length of the base platform 9 and extends to the outside of the base platform 9. The guide frame 8 outside the base platform 9 is located above the dial wheel 3. The guide frame 8 and the base platform 9 are arranged parallel to each other. The inclined arrangement can be achieved by setting the base platform 9. The straight pipe 11 is arranged parallel to the base platform 9, so the straight pipe 11 will be inclined, which facilitates the flow of alkali blocks between the top plate 14 and the bottom plate 12. The crushed alkali blocks can also roll into the wastewater.

[0029] The bend 10 is L-shaped and has a rectangular cross-section. The straight pipe 11 welded to the output end of the bend 10 has the same cross-section as the bend 10. The straight pipe 11 is rectangular. The top plate 14 and the bottom plate 12 are located on the upper and lower sides of the straight pipe 11, respectively. The straight pipe 11 is connected to the flow space formed by the top plate 14 and the bottom plate 12. By arranging the top plate 14 and the bottom plate 12 on the upper and lower sides of the straight pipe 11, the alkali block can flow directly between the top plate 14 and the bottom plate 12. When the top plate 14 and the bottom plate 12 move, they will move in opposite directions. When the straight pipe 11 is inserted between the top plate 14 and the bottom plate 12, it can prevent the top plate 14 or the bottom plate 12 from detaching from the straight pipe 11 and prevent the alkali block from falling directly onto the guide frame 8.

[0030] In implementation, a rotating rod 7 is installed inside the regulating tank 1, and a dial wheel 3 can be arranged on the rotating rod 7. When the rotating rod 7 is rotated by the motor, the dial wheel 3 on the rotating rod 7 will also rotate. Part of the dial wheel 3 is inside the electroplating wastewater, and the other part is outside the electroplating wastewater. When a dial plate 6 is installed on the side edge of the dial wheel 3, the dial plate 6 and the dial wheel 3 will form a spoon shape. When the dial wheel 3 rotates, it can scoop up the electroplating wastewater at the position of the dial plate 6, thereby achieving aeration. A chemical tank 5 is installed on the regulating tank 1. The alkali blocks inside the chemical tank 5 can enter between the top plate 14 and the bottom plate 12 through the bend pipe 10 and the straight pipe 11. Since the straight pipe 11 is arranged at an angle, the alkali blocks can be pushed towards the top plate 14 and the bottom plate 12. The alkali block rolls between the top plate 14 and the bottom plate 12 to achieve the flow of the reagent. When the alkali block enters between the top plate 14 and the bottom plate 12, the top plate 14 and the bottom plate 12 will move and move alternately. The top plate 14 and the bottom plate 12 are provided with protrusions 13, and the protrusions 13 between the top plate 14 and the bottom plate 12 are arranged alternately. When the alkali block enters between the top plate 14 and the bottom plate 12, it will be broken by the action of the top plate 14 and the bottom plate 12, thereby breaking the alkali block into small pieces. The alkali block will fall onto the guide frame 8 and finally slide into the electroplating wastewater, thus mixing with the wastewater. The entire treatment process can be automated, reducing the labor intensity of workers and reducing the treatment cost.

[0031] Both the top plate 14 and the bottom plate 12 are equipped with sliding rods 15, which are arranged horizontally. The sliding rods 15 on the top plate 14 and the bottom plate 12 are arranged parallel to each other. The straight pipe 11 corresponding to the sliding rod 15 is equipped with a support 16. The sliding rods 15 on the top plate 14 and the bottom plate 12 are slidably connected to the supports 16 on the straight pipe 11. The supports 16 are located on the upper and lower sides of the straight pipe 11, respectively. The sliding rods 15 can be restricted by the supports 16, so that the sliding rods 15 can move in the position of the supports 16, thereby cooperating with the top plate 14 and the bottom plate 12 to move. The top plate 14 and the bottom plate 12 are restricted by the sliding rods 15 and will not detach from the supports 16, thus ensuring the crushing of the alkali block.

[0032] The base 9 is provided with a first fixed seat 19, a second fixed seat 20 and a third fixed seat 23 respectively. The first fixed seat 19 is vertically arranged on the base 9. A movable frame 17 is slidably connected to the first fixed seat 19. The movable frame 17 and the first fixed seat 19 are arranged in a T-shape. One end of the movable frame 17 is connected through the first fixed seat 19. The movable frame 17 can be restricted by the first fixed seat 19, and the movable frame 17 can move in the position of the first fixed seat 19.

[0033] A movable rod 26 is rotatably connected to the second fixed base 20. The movable rod 26 passes through the second fixed base 20. A gear 21 is provided at one end of the movable rod 26. A rack 25 is meshed with the gear 21 below. The rack 25 is arranged parallel to the base 9 below. One end of the rack 25 is welded to the corresponding movable frame 17. When the movable frame 17 is connected to the rack 25, the movable frame 17 can drive the rack 25 to move. When the rack 25 meshes with the gear 21, the gear 21 can be driven by the rack 25. When the gear 21 rotates, the movable rod 26 can rotate, thereby realizing the rotation of the swing frame 27.

[0034] A crossbar 24 is slidably connected to the rack 25. The crossbars 24 are located on the rack 25 and are parallel to each other. The crossbars 24 are fixedly connected to the third fixed seat 23. A return spring 22 is sleeved on the crossbar 24. The return spring 22 is located between the third fixed seat 23 and the rack 25. One end of the return spring 22 is hooked on the rack 25. The connection between the crossbar 24 and the rack 25 can restrict the rack 25 and prevent it from dislodging. The return spring 22 can push the rack 25, thereby ensuring that the rack 25 is driven and reset, and thus is reciprocated by the lever 6.

[0035] A swing frame 27 is provided at the other end of the movable rod 26. The swing frame 27 is located on both sides of the movable rod 26. The swing frame 27 is arranged in a straight line. The swing frame 27 and the movable rod 26 are arranged in a T-shape. The swing frame 27 can drive the insertion rod 28, so that the insertion rod 28 can move in the vertical groove 30 of the vertical seat 29. During the movement, it can drive the vertical seat 29.

[0036] Both the top plate 14 and the bottom plate 12 are provided with vertical seats 29, which are arranged vertically on the top plate 14 and the bottom plate 12 respectively. The vertical seats 29 on the top plate 14 and the bottom plate 12 are provided with vertical grooves 30, which are arranged in a straight line. By driving the vertical seats 29, the top plate 14 and the bottom plate 12 can be driven, thereby ensuring the movement of the top plate 14 and the bottom plate 12. When the top plate 14 and the bottom plate 12 move, the alkali block can be crushed.

[0037] A rod 28 is inserted into the vertical groove 30 of the vertical seat 29. One end of the rod 28 is connected to the swing frame 27. The rod 28 is arranged vertically on the swing frame 27. The rod 28 and the swing frame 27 are arranged in an L-shape. Through the connection between the rod 28 and the vertical groove 30, the rod 28 will move in the vertical groove 30 after being driven by the swing frame 27, thereby ensuring that the movement trajectory of the top plate 14 and the bottom plate 12 will not affect each other when the swing frame 27 drives them to move.

[0038] In implementation, by installing a first fixed seat 19, a second fixed seat 20, and a third fixed seat 23 on the base platform 9, a movable frame 17 can be installed on the first fixed seat 19. The movable frame 17 can move on the first fixed seat 19. The roller 18 of the movable frame 17 is located in the rotation direction of the dial wheel 3. The dial wheel 3 can drive the dial plate 6 to rotate. When the dial plate 6 rotates to the position of the movable frame 17, it can push the movable frame 17, allowing the movable frame 17 to move on the first fixed seat 19, thereby driving the gear 21 to move horizontally. The rack 25 is meshed with the gear 21, and the rack 25 can drive the gear 21 to rotate. The gear 21 is mounted on the movable rod 26, which is fixed on the second fixed seat 20. The other side of 6 is connected to the swing frame 27. The insertion rod 28 on the swing frame 27 is inserted into the vertical groove 30 of the vertical seat 29. The vertical seat 29 is installed on the top plate 14 and the bottom plate 12 respectively. When the movable rod 26 rotates, the swing frames 27 on the upper and lower sides will move in two directions. When the swing frame 27 is connected to the vertical seat 29 through the insertion rod 28, the swing frame 27 can drive the vertical seat 29 to move. The top plate 14 and the bottom plate 12 can move in opposite directions. When the alkali block enters between the top plate 14 and the bottom plate 12, it can be crushed by the protrusion 13, thereby ensuring that the alkali block can be crushed into small particles. This ensures that the alkali block can quickly mix with the wastewater when it enters the wastewater, so that there is no need to arrange a separate stirring device, thereby reducing the treatment cost.

[0039] The working principle of this invention is as follows: A rotating rod 7 is installed in the regulating tank 1, and a dial wheel 3 can be arranged on the rotating rod 7. When the rotating rod 7 is rotated by the motor, the dial wheel 3 on the rotating rod 7 will also rotate. Part of the dial wheel 3 is located inside the electroplating wastewater, and the other part is located outside the electroplating wastewater. When a dial plate 6 is installed on the side edge of the dial wheel 3, the dial plate 6 and the dial wheel 3 will form a spoon shape. When the dial wheel 3 rotates, it can scoop up the electroplating wastewater at the position of the dial plate 6, thereby achieving aeration. A chemical tank 5 is installed on the regulating tank 1. The alkali block inside the chemical tank 5 can enter between the top plate 14 and the bottom plate 12 through the bend pipe 10 and the straight pipe 11. Since the straight pipe 11 is arranged at an incline, the alkali block can be moved between the top plate 14 and the bottom plate 12. The rolling mechanism facilitates the flow of the reagent. When the alkali block enters between the top plate 14 and the bottom plate 12, the top plate 14 and the bottom plate 12 move in an alternating manner. Both the top plate 14 and the bottom plate 12 are equipped with protrusions 13, which are arranged in an alternating pattern. When the alkali block enters between the top plate 14 and the bottom plate 12, it is broken down by the action of the top plate 14 and the bottom plate 12, thus breaking the alkali block into smaller pieces. The alkali block then falls onto the guide frame 8 and eventually slides into the electroplating wastewater, mixing with it. The entire treatment process can be automated, reducing the labor intensity of workers and lowering treatment costs. This is achieved by installing a first fixed... The system comprises a fixed base 19, a second fixed base 20, and a third fixed base 23. A movable frame 17 can be installed on the first fixed base 19, allowing it to move within the base. The roller 18 of the movable frame 17 is located in the rotation direction of the dial wheel 3, which drives the dial plate 6 to rotate. When the dial plate 6 rotates to the position of the movable frame 17, it pushes the movable frame 17, enabling it to move within the first fixed base 19. This, in turn, drives the gear 21 to move horizontally. A rack 25 meshes with the gear 21, driving it to rotate. The gear 21 is mounted on a movable rod 26, which is fixed to the second fixed base 20. The other side of the movable rod 26 is connected to... The swing frame 27 has a rod 28 inserted into the vertical groove 30 of the vertical seat 29. The vertical seat 29 is installed on the top plate 14 and the bottom plate 12 respectively. When the movable rod 26 rotates, the swing frame 27 on the upper and lower sides will move in two directions. When the swing frame 27 is connected to the vertical seat 29 through the rod 28, the swing frame 27 can drive the vertical seat 29 to move. The top plate 14 and the bottom plate 12 can move in opposite directions. When the alkali block enters between the top plate 14 and the bottom plate 12, it can be crushed by the protrusion 13, thereby ensuring that the alkali block can be crushed into small particles. This ensures that the alkali block can quickly mix with the wastewater when it enters the wastewater, so that there is no need to arrange a separate stirring device, thereby reducing the treatment cost.
