Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a wastewater treatment device for carbon material production. Background Technology

[0002] Nanomaterials mainly include graphene, carbon nanotubes, nanographite, carbon fiber, fullerene, etc. Among them, graphene and carbon nanotubes are widely used as electrode materials, composite materials, optical waveguide materials, magnetic materials, etc. due to their excellent physical and chemical properties, such as electrical conductivity, thermal conductivity and corrosion resistance. They are widely used in aerospace, electric vehicles and intelligent manufacturing fields.

[0003] In the production process of carbon materials, sulfuric acid or hydrochloric acid is used to pickle the carbon materials. After pickling, they need to be rinsed with clean water. Therefore, wastewater will be generated. The wastewater needs to be treated before it is discharged.

[0004] Currently, various chemicals are often used to treat factory wastewater. Existing wastewater treatment equipment generally pours the chemicals directly into the reaction chamber. These chemicals are usually in powder form and tend to stick to the upper part of the inner wall of the reaction chamber. The upper part of the inner wall of the reaction chamber is generally difficult to be wetted by wastewater. Over time, the chemicals tend to clump on the inner wall of the reaction chamber and are difficult to remove. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment device for carbon material production, in order to solve the problem that in existing wastewater treatment devices, the reagents tend to stick to the inner wall of the reaction chamber when added.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A wastewater treatment device for carbon material production, comprising:

[0008] The treatment tank has an inlet at the top and a first outlet at the bottom, with a first valve on the first outlet. The treatment tank is used to treat sewage, where chemicals and sewage are mixed to treat the sewage. The inlet is used for sewage to enter the treatment tank, the first outlet is used for sewage to be discharged from the treatment tank, and the first valve is used to control the opening and closing of the first outlet.

[0009] A drawer, located on the upper part of one side of the treatment box, is slidably connected to the treatment box. When the drawer is closed, the water inlet is located directly above the drawer. The drawer includes a drawer door, two drawer side panels, a drawer bottom panel, and a drawer back panel. The drawer door, two drawer side panels, and drawer back panel are respectively sealed to the four sides of the drawer bottom panel. The drawer door, two drawer side panels, and drawer back panel are arranged together, with the drawer door and drawer back panel facing each other, and the two drawer side panels facing each other. A long strip-shaped drainage notch is provided at the bottom of the drawer back panel. An overflow notch is provided at the top of the panel, and a first sealing ring is embedded in the drawer door to ensure a sealed connection between the drawer door and the treatment box when the drawer is closed. The drawer is used to store medicines and consists of a drawer door, two drawer side panels, a drawer bottom panel, and a drawer back panel. A drainage notch is provided to allow water inside the drawer to flow out of the drawer, and an overflow notch is provided to allow water inside the drawer to overflow out of the drawer. The first sealing ring is used to seal between the drawer door and the side wall of the treatment box to prevent sewage from flowing out of the treatment box from the connection between the drawer door and the treatment box when the drawer is closed.

[0010] A filter box is located below the treatment tank. The first outlet is connected to the top of the filter box, and the bottom of the filter box has a second outlet. A filter plate is provided between the first outlet and the second outlet, and a second valve is provided on the second outlet. The filter box is used for filtering sewage. Specifically, the sewage is filtered by the filter plate installed in the sewage tank. The filtered sewage is discharged from the filter box through the second outlet, and the second valve is used to control the opening and closing of the second outlet.

[0011] This invention features a drawer for holding the medicine and a water inlet for wastewater to enter the treatment tank. By placing the water inlet directly above the drawer, the wastewater can dissolve the medicine inside the drawer, which then flows out through a drain and overflow outlet. Simultaneously, as the wastewater enters the treatment tank, it continuously flushes the drawer, preventing the medicine from adhering inside. Therefore, in use, the medicine can be directly placed into the drawer; the wastewater will flow into the drawer, mix with the medicine, and continuously flush the drawer, making it difficult for the medicine to adhere inside the treatment tank or the drawer. Even if the medicine does adhere inside the drawer, it can be easily pulled out for cleaning. The continuous flow of wastewater into the drawer also facilitates mixing of the medicine and wastewater, accelerating the process of uniform mixing.

[0012] Furthermore, the inner wall of the processing box is provided with a horizontal support plate, the drawer is located on the support plate, the bottom surface of the drawer bottom plate is provided with two guide rails, and the support plate is provided with guide grooves that cooperate with the guide rails to allow the drawer to slide with the processing box. The length direction of the guide rails is consistent with the drawer's pull-out direction and the length direction of the drawer bottom plate. The two guide rails are distributed on both sides of the width direction of the drawer bottom plate. The support plate is used to support the drawer, and the guide rails and guide grooves cooperate to realize the sliding connection between the drawer and the processing box. The guide rails and guide grooves cooperate to guide each other.

[0013] Furthermore, a reinforcing rod is provided between the support plate and the processing box. One end of the reinforcing rod is connected to the processing box, and the other end is connected to the bottom of the support plate away from the side wall of the processing box. The reinforcing rod is used to support the support plate.

[0014] Furthermore, a stop is provided on the side of the top surface of the support plate away from the side wall of the processing box. The stop is used to limit the movement distance of the drawer. When the drawer is closed, the back panel of the drawer is just blocked by the stop. At this time, the drawer door is also flush with the outer side of the processing box. At this time, the first sealing ring is located between the processing box and the drawer door, realizing the sealing between the processing box and the drawer door.

[0015] Furthermore, a stirring motor is provided on the top of the treatment tank. The stirring motor is connected to a stirring shaft via a coupling. The stirring shaft passes through the top of the treatment tank and extends into the treatment tank. A stirring support rod is provided on the lower section of the stirring shaft. The stirring motor is used to drive the stirring shaft to rotate, which in turn drives the stirring support rod to rotate, thereby agitating the wastewater. This can accelerate the uniform mixing of the agent and the wastewater, and speed up the treatment speed of the agent on the wastewater. The coupling is used to connect the motor shaft of the stirring motor and the stirring shaft.

[0016] Furthermore, a connecting pipe is provided on the outside of the treatment tank. The bottom end of the connecting pipe is connected to the upper part of the filter tank. The connection point between the bottom end of the connecting pipe and the upper part of the filter tank is located on the side of the filter plate away from the second outlet. Multiple auxiliary outlets are sequentially opened from bottom to top on the lower side of the treatment tank. All auxiliary outlets are connected to the connecting pipe. Each auxiliary outlet is equipped with an auxiliary valve. Wastewater is discharged from the treatment tank through these auxiliary outlets. Because the auxiliary outlets are arranged sequentially from low to high, opening auxiliary outlets at different heights can preferentially discharge wastewater in the vicinity, accelerating the wastewater filtration speed. Specifically, after wastewater treatment, sediment may form. For example, when flocculant is added, sediment may be generated. The sediment is located at the bottom or lower part of the treatment tank. The filtration speed depends on the amount of sediment. As the wastewater in the treatment tank decreases, the amount of sediment gradually increases. If we directly open the first outlet at the bottom of the treatment tank, the sediment at the bottom will enter the filter tank first. This sediment will be blocked by the filter plate, affecting the filtration speed of wastewater with less sediment later. If we open the auxiliary outlets sequentially from top to bottom, the wastewater in the upper layer of the treatment tank will flow into the filter tank first for filtration, followed by the wastewater with more sediment in the lower layer. Because the initial sediment content of the wastewater is low, the amount of sediment intercepted by the filter plate is also low, resulting in a fast filtration speed. The wastewater flowing into the filter tank later has a higher sediment content, leading to a slower filtration speed. Therefore, the auxiliary outlets can accelerate the wastewater filtration speed. Connecting pipes are used to connect the auxiliary outlets to the filter tank, and auxiliary valves are used to control the opening and closing of the auxiliary outlets.

[0017] Furthermore, the filter box is provided with a cleaning door on the side, which is used to clean the filtered substances on the filter plate.

[0018] Furthermore, the filter box is equipped with a scraper, which contacts the side of the filter plate opposite to the second outlet. The scraper is equipped with a pull rod that passes through the filter box and extends to the outside of the filter box. A second sealing ring is embedded in the pull rod. The scraper is used to clean the filtered material on the filter plate. The guide strip and guide groove cooperate to achieve a sliding connection between the scraper and the inner wall of the filter box. The pull rod is used to push and pull the scraper outside the filter box. When the scraper is pulled, the material on the filter plate can be pulled to the vicinity of the cleaning door, reducing the clogging of the filter plate by the filtered material, which can accelerate the sewage filtration speed and facilitate cleaning.

[0019] Furthermore, the drawer door is equipped with a handle for easy operation.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] (1) This utility model uses a drawer for storing medicines and an inlet for sewage to enter the treatment tank. By placing the inlet directly above the drawer, the sewage can dissolve the medicines in the drawer and flow out through the drain and overflow gaps. At the same time, the sewage will continuously flush the drawer when entering the treatment tank, making it difficult for the medicines to stick in the drawer. Therefore, when using this device, you can simply put the medicines into the drawer. The sewage will flow into the drawer, mix with the medicines, and continuously flush the drawer, making it difficult for the medicines to stick in the treatment tank or the drawer. Even if the medicines stick in the drawer, you can simply pull the drawer out for easy cleaning. The continuous flow of sewage into the drawer also helps the medicines and sewage mix, which can speed up the process of mixing the medicines and sewage evenly.

[0022] (2) This utility model uses auxiliary outlets to discharge wastewater from the treatment tank. Since the auxiliary outlets are arranged sequentially from low to high, opening outlets at different heights can preferentially discharge wastewater near those locations, accelerating the wastewater filtration speed. Specifically, after treatment, wastewater may produce sediment. For example, when flocculants are added, sediment may form. The sediment is located at the bottom or lower part of the treatment tank, depending on the amount. The amount of sediment gradually increases from high to low within the treatment tank. Therefore, if we directly open the outlets located at different heights within the treatment tank... The first outlet at the bottom allows sediment from the bottom of the treatment tank to enter the filter tank first. This sediment is blocked by the filter plate, affecting the filtration speed of subsequent wastewater with less sediment. If the auxiliary outlets are opened sequentially from top to bottom, the wastewater in the upper layer of the treatment tank will flow into the filter tank first for filtration, and the wastewater with more sediment in the lower layer will flow into the filter tank later for filtration. Because the initial wastewater has less sediment, the amount of sediment intercepted by the filter plate is also less, resulting in a faster filtration speed. The wastewater with more sediment flowing into the filter tank later will have a slower filtration speed. Therefore, the auxiliary outlets can accelerate the wastewater filtration speed.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figure 1-4 As shown, this embodiment provides a wastewater treatment device for carbon material production, comprising:

[0030] The treatment tank 1 has an inlet 2 at the top and a first outlet 3 at the bottom, with a first valve 4 on the first outlet 3. The treatment tank 1 is used to treat sewage. The agent and sewage are mixed in the treatment tank 1 to treat the sewage. The inlet 2 is used for sewage to enter the treatment tank 1, and the first outlet 3 is used for sewage to be discharged from the treatment tank 1. The first valve 4 is used to control the opening and closing of the first outlet 3.

[0031] A drawer is located on the upper part of one side of the treatment box 1 and is slidably connected to the treatment box 1. When the drawer is closed, the water inlet 2 is located directly above the drawer. The drawer includes a drawer door 5, two drawer side panels 6, a drawer bottom panel 7, and a drawer back panel 8. The drawer door 5, the two drawer side panels 6, and the drawer back panel 8 are respectively sealed to the four sides of the drawer bottom panel 7. The drawer door 5, the two drawer side panels 6, and the drawer back panel 8 are arranged in a closed configuration. The drawer door 5 and the drawer back panel 8 are arranged opposite each other. The two drawer side panels 6 are arranged opposite each other. A long strip-shaped drainage notch 28 is opened at the bottom of the drawer back panel 8. The top of the plate 8 is provided with an overflow notch 29, and a first sealing ring 9 is embedded in the drawer door 5 so that the drawer door 5 and the treatment box 1 are sealed together when the drawer is closed. The drawer is used to hold medicine. The drawer is composed of the drawer door 5, two drawer side plates 6, drawer bottom plate 7 and drawer back plate 8. The drainage notch 28 is provided to allow water in the drawer to flow out of the drawer. The overflow notch 29 is provided to allow water in the drawer to overflow out of the drawer. The first sealing ring 9 is provided to seal between the drawer door 5 and the side wall of the treatment box 1 to prevent sewage from flowing out of the treatment box 1 from the connection between the drawer door 5 and the treatment box 1 when the drawer is closed.

[0032] A filter box 10 is located below the treatment box 1. The first outlet 3 is connected to the top of the filter box 10. The bottom of the filter box 10 is provided with a second outlet 11. A filter plate 12 is provided between the first outlet 3 and the second outlet 11. A second valve 13 is provided on the second outlet 11. The filter box 10 is used for filtering sewage. Specifically, the filter plate 12 is provided in the sewage tank to filter sewage. The filtered sewage is discharged from the filter box 10 through the second outlet 11. The second valve 13 is used to control the opening and closing of the second outlet 11.

[0033] In this embodiment, areas in contact with sewage need to be treated to resist corrosion, for example, by using corrosion-resistant materials or by spraying a corrosion-resistant coating.

[0034] This invention features a drawer for storing medicines and an inlet 2 for wastewater to enter the treatment tank 1. By positioning the inlet 2 directly above the drawer, the wastewater can dissolve the medicines inside and allow them to flow out through the drain 28 and overflow 29. Simultaneously, as the wastewater enters the treatment tank 1, it continuously flushes the drawer, preventing the medicines from adhering. Therefore, in use, the medicines can be placed directly into the drawer, where wastewater will flow in, mix with the medicines, and continuously flush the drawer, making it difficult for the medicines to adhere to either the treatment tank 1 or the drawer. Even if the medicines do adhere to the drawer, it can be easily removed for cleaning. The continuous flow of wastewater into the drawer also facilitates mixing of the medicines and wastewater, accelerating the process of uniform mixing.

[0035] Furthermore, the inner wall of the processing box 1 is provided with a horizontal support plate 14, the drawer is located on the support plate 14, and the bottom surface of the drawer bottom plate 7 is provided with two guide rails 30. The support plate 14 is provided with a guide groove 31 that cooperates with the guide rails 30, so that the drawer and the processing box 1 are slidably connected. The length direction of the guide rails 30 is consistent with the drawer's pull-out direction and the length direction of the drawer bottom plate 7. The two guide rails 30 are distributed on both sides of the width direction of the drawer bottom plate 7. The support plate 14 is used to support the drawer, and the guide rails 30 and guide grooves 31 cooperate to realize the sliding connection between the drawer and the processing box 1. The guide rails 30 and guide grooves 31 cooperate to guide each other. In this embodiment, the guide groove 31 can be a dovetail groove, and the shapes of the guide rails 30 and guide grooves 31 are matched.

[0036] Furthermore, a reinforcing rod 15 is provided between the support plate 14 and the processing box 1. One end of the reinforcing rod 15 is connected to the processing box 1, and the other end is connected to the bottom of the support plate 14 away from the side wall of the processing box 1. The reinforcing rod 15 is used to support the support plate 14. In this embodiment, there are at least two reinforcing rods 15 to achieve a better strengthening effect.

[0037] Furthermore, a stop 16 is provided on the side of the top surface of the support plate 14 away from the side wall of the processing box 1. The stop 16 is used to limit the movement distance of the drawer. When the drawer is closed, the drawer back plate 8 is just abutted by the stop 16. At this time, the drawer door 5 is also flush with the outer side of the processing box 1. At this time, the first sealing ring 9 is located between the processing box 1 and the drawer door 5, realizing the seal between the processing box 1 and the drawer door 5.

[0038] Furthermore, a stirring motor 27 is provided on the top of the treatment tank 1. The stirring motor 27 is connected to a stirring shaft 17 via a coupling. The stirring shaft 17 passes through the top of the treatment tank 1 and extends into the treatment tank 1. A stirring support rod 18 is provided on the lower section of the stirring shaft 17. The stirring motor 27 is used to drive the stirring shaft 17 to rotate, thereby driving the stirring support rod 18 to rotate, realizing the stirring of sewage. This can accelerate the uniform mixing of the agent and sewage and speed up the treatment speed of the agent on the sewage. The coupling is used to connect the motor shaft of the stirring motor 27 and the stirring shaft 17. In this embodiment, the bottom end of the stirring shaft 17 and the bottom end of the treatment tank 1 can be rotatably connected by a bearing seat to enhance the stability of the stirring shaft 17 when rotating.

[0039] Furthermore, a connecting pipe 19 is provided on the outside of the treatment tank 1. The bottom end of the connecting pipe 19 is connected to the upper part of the filter tank 10. The connection point between the bottom end of the connecting pipe 19 and the upper part of the filter tank 10 is located on the side of the filter plate 12 away from the second outlet 11. Multiple auxiliary outlets 20 are sequentially opened from bottom to top on the lower side of the treatment tank 1. All of the multiple auxiliary outlets 20 are connected to the connecting pipe 19. An auxiliary valve 21 is provided on each auxiliary outlet 20. Wastewater is discharged from the treatment tank 1 through the auxiliary outlets 20. Since the auxiliary outlets 20 are arranged sequentially from low to high, opening the auxiliary outlets 20 at different heights can preferentially discharge the wastewater in the vicinity, thus accelerating the wastewater filtration speed. Specifically, after the wastewater is treated, sediment may be generated. For example, when a flocculant is added, sediment may be generated. The sediment is located at the bottom or lower part of the treatment tank 1. The specific filtration speed depends on the amount of sediment. In treatment tank 1, the amount of sediment gradually increases from high to low. If we directly open the first outlet 3 at the bottom of treatment tank 1, the sediment at the bottom of treatment tank 1 will enter the filter tank 10 first. This sediment is blocked by the filter plate 12, affecting the filtration speed of subsequent wastewater with less sediment. If we open the auxiliary outlets 20 sequentially from top to bottom, the upper layer of wastewater in treatment tank 1 flows into the filter tank 10 for filtration first, followed by the lower layer with more sediment. Because the initial sediment content of the wastewater is low, the amount of sediment intercepted by the filter plate 12 is also low, resulting in a fast filtration speed. Later, the wastewater flowing into the filter tank 10 has a higher sediment content, resulting in a slower filtration speed. Therefore, the auxiliary outlets 20 can accelerate the wastewater filtration speed. A connecting pipe 19 connects the auxiliary outlets 20 to the filter tank 10, and an auxiliary valve 21 controls the opening and closing of the auxiliary outlets 20.

[0040] In this embodiment, the top of the connecting pipe 19 can be sealed off or connected to the auxiliary outlet 20 at the top. In this embodiment, an observation window can be provided on the side wall of the treatment tank 1. The observation window can be transparent glass or other transparent and corrosion-resistant materials to facilitate observation of the water level and sedimentation position of the sewage in the treatment tank 1.

[0041] Furthermore, the filter box 10 is provided with a cleaning door 22 on its side. The cleaning door 22 is used to clean the filtered substances on the filter plate 12. In this embodiment, the cleaning door 22 can be connected to the filter box 10 by a hinge or other existing connection methods, and the cleaning door 22 is sealed to the filter box 10.

[0042] Furthermore, the filter box 10 is provided with a scraper 23, which contacts the side of the filter plate 12 facing away from the second outlet 11. The scraper 23 is provided with a pull rod 24, which passes through the filter box 10 and extends to the outside of the filter box 10. A second sealing ring 25 is embedded in the pull rod 24. The scraper 23 is used to clean the filtered material on the filter plate 12. The guide strip and guide groove are used to achieve a sliding connection between the scraper 23 and the inner wall of the filter box 10. The pull rod 24 is used to push and pull the scraper 23 outside the filter box 10. When the scraper 23 is pulled, the material on the filter plate 12 can be pulled to the vicinity of the cleaning door 22, reducing the clogging of the filter plate 12 by the filtered material, which can accelerate the sewage filtration speed and facilitate cleaning. The second sealing ring 25 is used for sealing the connection between the pull rod 24 and the filter box 10.

[0043] Furthermore, the drawer door 5 is provided with a handle 26 for easy pulling of the drawer.

[0044] Working principle: First, open the drawer and pour the wastewater treatment agent into it. Then close the drawer to seal the drawer door 5 and treatment tank 1. Next, inject wastewater into the treatment tank 1 through inlet 2. When injecting wastewater, start with a small flow rate, allowing the wastewater to fall directly into the drawer from inlet 2 and mix with the agent inside, slowly dissolving it. After falling into the drawer, the wastewater will flow out from drain opening 28. However, because drain opening 28 is small, the wastewater will slowly fill the drawer. At this point, more agent will be dissolved by the wastewater. When the drawer is full of wastewater, it will flow out from overflow opening 29. Once the drawer is full, the wastewater injection rate can be gradually increased to avoid excessive water flow at the beginning. Excessive flow impact causes the chemicals to splash onto the inner wall of treatment tank 1. After the wastewater is injected, the chemicals also dissolve in the wastewater. At this time, the stirring motor 27 can be turned on to drive the stirring shaft 17 to rotate, thereby mixing the wastewater and completing the wastewater treatment. After the wastewater treatment is completed and the sedimentation is complete, the auxiliary outlets 20 are opened sequentially from top to bottom. Specifically, the top auxiliary outlet 20 is opened first. When the wastewater level is below this auxiliary outlet 20, the next auxiliary outlet 20 is opened, and so on, until all the auxiliary outlets 20 are opened. After no more wastewater flows out of the auxiliary outlets 20, the first outlet 3 is opened to drain the last wastewater in treatment tank 1.

[0045] It should be noted that although the present invention has been disclosed above with specific embodiments, the above embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
