Description

Technical Field

[0001] This invention belongs to the field of dredging machinery technology, and more specifically relates to a drilling mud waste destabilization and separation device using electrocoagulation method. Background Technology

[0002] During drilling operations, a large amount of drilling mud waste containing suspended particles, colloids, and other pollutants is generated. Direct discharge of this waste would cause environmental pollution, thus requiring destabilization and separation treatment. Electrocoagulation technology, due to its high efficiency and lack of secondary pollution, is widely used in the destabilization and separation of drilling mud waste. Its core principle is to use the electrochemical reaction generated by energizing electrode plates to destabilize suspended particles and colloids in the wastewater, causing them to aggregate into flocs, thereby achieving solid-liquid separation.

[0003] However, existing electrocoagulation destabilization and separation devices still have many shortcomings in practical applications:

[0004] On the one hand, the accumulation of flocculants on the electrode plate surface is a prominent problem. During the electrocoagulation reaction, pollutants in the wastewater continuously accumulate on the electrode plate surface to form flocculants. If not removed in time, the flocculants will gradually cover the active area of ​​the electrode, resulting in a significant reduction in the effective contact area between the electrode and the wastewater, a significant decrease in the electrochemical reaction rate, and ultimately a decline in flocculant efficiency. Existing solutions to this problem have shortcomings: manual cleaning requires frequent shutdowns, which not only interrupts the treatment process and increases labor intensity but also extends the treatment cycle due to shutdowns; fixed scraping structures are difficult to adapt to the dynamic reaction process of the electrode plates, have a limited scraping range, and are prone to local flocculant residue, leading to a decrease in treatment efficiency after long-term operation.

[0005] On the other hand, air bubbles adhering to the electrode plate surface hinder the reaction. During electrocoagulation, an electrolytic reaction occurs when electricity is applied to the electrode plate, generating a large number of bubbles such as hydrogen and oxygen. These bubbles easily adhere to the electrode plate surface, forming an air film. This air film significantly increases the contact resistance between the electrode and the wastewater, reduces current efficiency, and simultaneously hinders the migration of substances to be treated in the wastewater to the electrode surface. This results in uneven and incomplete flocculation reactions, prolonging treatment time and causing fluctuations in effluent quality, making it difficult to meet the process requirements for stable treatment. Currently, existing devices lack a targeted bubble removal mechanism and cannot effectively solve the negative impacts of bubble adhesion.

[0006] Therefore, a drilling mud waste destabilization and separation device utilizing electrocoagulation method is proposed. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown herein can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0045] refer to Figures 1-7 As shown, this is a specific embodiment of a drilling mud waste destabilization and separation device using electrocoagulation method according to the present invention, which includes an installation operation frame 100 and a destabilization and separation body 200, wherein the destabilization and separation body 200 is fixedly mounted on the installation operation frame 100.

[0046] The mounting frame 100 is used to provide installation space and a personnel operation platform for the destabilization and separation body 200;

[0047] The destabilization and separation main body 200 includes a drive component 201, a flocculation and filtration component 202, a flocculation scraping component 207, and a power switching control component;

[0048] The flocculation filtration assembly 202 includes an electrocoagulation electrode column 2026, which is connected to a drive assembly 201. The electrocoagulation electrode column 2026 is used to flocculate substances in wastewater by electrocoagulation. The flocculation filtration assembly 202 also includes a filtration mechanism for separating the flocculated substances from the water.

[0049] The flocculation scraping component 207 is connected to the drive component 201 and is used to scrape off the flocculated material on the electrocoagulation electrode column 2026.

[0050] Drive assembly 201 is used to provide driving force for electrocoagulation electrode column 2026 or flocculation scraping assembly 207;

[0051] The power switching control component is used to switch the connection between the drive component 201 and the flocculation filter component 202 and the flocculation scraping component 207, and to turn the energized state of the electrocoagulation electrode column 2026 on or off by means of circuit control during switching.

[0052] The installation and operation frame 100 serves as the installation space and personnel operating platform, providing basic support for the destabilization and separation main body 200 fixed thereon. During operation, the power switching control component first switches to establish a transmission connection between the drive component 201 and the flocculation and filtration component 202. Simultaneously, during this switching process, the circuit controls the energization of the electrocoagulation electrode column 2026. The drive component 201 then provides driving force to the flocculation and filtration component 202, driving the electrocoagulation electrode column 2026 to flocculate substances in the wastewater through electrocoagulation. After flocculation... The filtration mechanism of filter assembly 202 separates the flocculated material from the water; then the power switching control assembly switches again, establishing a transmission connection between drive assembly 201 and flocculation scraping assembly 207. At the same time, during the switching, the power supply to electrocoagulation electrode column 2026 is turned off by circuit control. Drive assembly 201 then provides driving force to flocculation scraping assembly 207. Flocculation scraping assembly 207 operates to scrape the flocculated material on electrocoagulation electrode column 2026. Through the power switching control assembly, the alternation of flocculation treatment and flocculation scraping processes is achieved.

[0053] Furthermore, the drive assembly 201 includes a drive mounting base 2011, and a drive output shaft 2012 is fixedly provided at the top of the inner wall of the drive mounting base 2011. The output end of the drive output shaft 2012 is divided into three sections, which are, from top to bottom, a smooth section one, a flat shaft section, a smooth section two, and a mounting section.

[0054] A limiting and stabilizing sleeve 2014 is fixedly sleeved on the outer periphery of the flat shaft section of the drive output shaft 2012. An upper triangular transmission frame 2013 is sleeved on the smooth section one of the drive output shaft 2012, and a lower triangular transmission frame 2016 is sleeved on the smooth section two. The top projections of the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016 overlap, including but not limited to being equilateral triangles. Multiple transmission links 2015 are arranged equidistantly between the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016, including but not limited to three. The three transmission links 2015 are evenly distributed at the three corners of the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016, and the three transmission links 2015 are rotatably connected to the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016.

[0055] A transmission sleeve 2019 is fitted on the mounting section of the drive output shaft 2012. An internal gear transmission ring 2017 is fixed on the outer circumferential surface of the transmission sleeve 2019 by multiple fixed connecting rods 2018. An internal gear ring is provided on the inner circumferential surface of the internal gear transmission ring 2017. The internal gear transmission ring 2017 meshes with three transmission connecting rods 2015 through the internal gear ring. The end of the mounting section away from the smooth section two is fixedly connected to one end of the electrocoagulation electrode column 2026.

[0056] Multiple positioning holes are evenly distributed along the axis of the internal gear transmission ring 2017, and multiple positioning holes are evenly distributed along the axis of the upper triangular transmission frame 2013.

[0057] When the drive assembly 201 is working, the drive mounting base 2011 provides the mounting foundation, and the drive output shaft 2012 fixed at the top of its inner wall rotates as a power output component. The mounting section drives the transmission sleeve 2019 sleeved on it to move synchronously. The transmission sleeve 2019 drives the internal gear transmission ring 2017 to rotate through multiple fixed connecting rods 2018. The internal gear transmission ring 2017 meshes with three transmission connecting rods 2015 through the internal gear ring. The three transmission connecting rods 2015 are respectively rotatably connected to the upper triangular transmission frame 2013 and the lower triangular transmission frame 2015. The moving frame 2016 is evenly distributed at the corners of the two, thus driving the upper triangular transmission frame 2013 to move synchronously on the smooth section one and the lower triangular transmission frame 2016 on the smooth section two. At the same time, it drives the limiting and stabilizing sleeve 2014 on the flat shaft section of the output shaft 2012 to play a limiting and stabilizing role. The end of the installation section away from the smooth section two drives the electrocoagulation electrode column 2026 to move. During the movement, the positioning hole one of the internal gear transmission ring 2017 and the positioning hole two of the upper triangular transmission frame 2013 can cooperate with the power switching control component to realize the switching of positioning.

[0058] Furthermore, the flocculation and filtration assembly 202 includes a transmission limiting sleeve 2028 sleeved on the outer periphery of the transmission sleeve 2019 and used to limit the transmission sleeve 2019. A processing chamber housing 2021 is sleeved on the outer shaft of the transmission limiting sleeve 2028. The inner wall of the processing chamber housing 2021 is symmetrically provided with through grooves. Filter plate slide rails 2024 are fixedly provided in the two through grooves. Filter plates 2022 are slidably provided on the two filter plate slide rails 2024. Multiple filter holes are evenly provided on the filter plates 2022. Multiple protruding balls are also evenly provided on the upper surface of the filter plates 2022 along the axis.

[0059] The electrocoagulation electrode column 2026 is fixedly provided with a transmission turntable 2025 at one end away from the transmission sleeve 2019. Multiple convex balls are evenly provided along the axis on the lower end surface of the transmission turntable 2025. Under normal conditions, convex balls one and convex balls two are distributed alternately.

[0060] A connecting shaft is fixedly provided at the bottom center of the transmission turntable 2025. The end of the connecting shaft opposite to the transmission turntable 2025 passes through the filter plate 2022, and a filter plate scraper 2023 for scraping the filter plate 2022 is fixedly provided at the end of the shaft.

[0061] The transmission limiting sleeve 2028 is fitted around the outer periphery of the transmission sleeve 2019, limiting the position of the transmission sleeve 2019 and providing a stable foundation for the operation of subsequent components. The processing chamber housing 2021 is fitted onto the outer shaft of the transmission limiting sleeve 2028, and filter plate slide rails 2024 are fixed in the symmetrical through grooves on its inner wall. The filter plate 2022 is mounted on the two filter plate slide rails 2024 and can slide along the filter plate slide rails 2024.

[0062] When the end of the electrocoagulation electrode column 2026 that is away from the transmission sleeve 2019 rotates, it will drive the transmission turntable 2025 fixed thereto to rotate synchronously. The second convex ball on the lower end face of the transmission turntable 2025 rotates with it. Since the second convex ball and the first convex ball on the upper end face of the filter plate 2022 are staggered under normal conditions, the second convex ball will come into contact with the first convex ball and interact with it during the rotation, pushing the filter plate 2022 to slide along the filter plate slide rail 2024.

[0063] As the filter plate 2022 slides, its own filter holes operate synchronously to separate and filter flocculated materials from the water in the wastewater. At the same time, the connecting shaft at the bottom center of the transmission turntable 2025 rotates with the transmission turntable 2025. The end of the connecting shaft opposite to the transmission turntable 2025 passes through the filter plate 2022, and the filter plate scraper 2023 fixed to the outer periphery of its protruding end also rotates accordingly. During the filtration operation of the filter plate 2022, the filter plate scraper 2023 continuously scrapes the surface of the filter plate 2022 to prevent flocculated materials from clogging the filter holes.

[0064] Furthermore, the power switching control component includes a switching base 2081 fixedly mounted on the transmission limiting sleeve 2028. The power switching control component is located in the space of the drive mounting base 2011. The switching base 2081 is provided with a sliding groove, and a switching slider 2082 is slidably mounted in the sliding groove. An upper positioning plate 2083 and a lower positioning plate 2084 are fixedly mounted on the side of the switching slider 2082 away from the switching base 2081 along the height direction from top to bottom. A positioning block one and a positioning block two are respectively provided on the adjacent sides of the upper positioning plate 2083 and the lower positioning plate 2084. The positioning block one and the positioning block two are respectively used to cooperate with the positioning hole one and the positioning hole two.

[0065] An electromagnet is provided at the bottom of the slide groove of the switching base 2081, and a permanent magnet is provided at the bottom of the switching slider 2082 located in the slide groove. The electromagnet is electrically connected to the electrode plate on the electrocoagulation electrode column 2026. When the electromagnet is energized, the electrode plate is also energized.

[0066] The power switching control component is mounted on a switching base 2081 fixed on a transmission limit sleeve 2028, and is located within the space of the drive mounting base 2011. The working process is as follows: When positioning is required, the electromagnet at the bottom of the slide groove of the switching base 2081 is energized. Since the electromagnet is electrically connected to the electrode plate on the electrocoagulation electrode column 2026, the electrode plate of the electrocoagulation electrode column 2026 is synchronously energized. After the electromagnet is energized, it generates a magnetic force with the permanent magnet at the bottom of the slide groove of the switching slider 2082, pushing the switching slider 2082 to slide along the slide groove of the switching base 2081. The upper positioning plate 2083 and the lower positioning plate 2084 on the side of the switching slider 2082 away from the switching base 2081 move synchronously with it, so that the positioning block one on the upper positioning plate 2083 corresponds to the positioning hole one of the internal gear transmission ring 2017, and the positioning block two on the lower positioning plate 2084 corresponds to the positioning hole two of the upper triangular transmission frame 2013, thus completing the positioning action. When positioning is not required, the electromagnet is de-energized, and the electrode plates of the electrocoagulation electrode column 2026 are also de-energized simultaneously. The switching slider 2082 resets along the slide groove under its own gravity or the opposing force between the permanent magnet and the electromagnet. Positioning block one and positioning block two disengage from positioning hole one and positioning hole two respectively, restoring the initial state.

[0067] Furthermore, the flocculation scraping assembly 207 includes a transmission pulley 2071 rotatably mounted on the transmission limiting sleeve 2028. The transmission pulley 2071 and the transmission sleeve 2019 are connected by a belt drive. A bidirectional threaded screw 2072 is fixedly mounted on one end of the transmission pulley 2071 away from the transmission limiting sleeve 2028. A movable limiting block 2073 is fixedly mounted on one end of the bidirectional threaded screw 2072 away from the transmission pulley 2071. A scraping ring movable seat 2076 is threadedly mounted on the bidirectional threaded screw 2072. An installation groove is opened on the other end of the scraping ring movable seat 2076. A flocculation scraping ring 2075 is provided in the installation groove. An annular space is left between the outer wall of the flocculation scraping ring 2075 and the inner wall of the installation groove. A plurality of transmission balls 2074 are provided in the annular space. The flocculation scraping ring 2075 is rotatably connected to the scraping ring movable seat 2076 through the plurality of transmission balls 2074.

[0068] Multiple flower-shaped grooves are evenly opened along the axis on the outer wall of the electrocoagulation electrode column 2026, and an electrode plate is provided in each flower-shaped groove. The inner wall of the flocculation scraping ring 2075 is provided with splines that fit with the flower-shaped grooves.

[0069] The operation of the flocculation scraping component 207 revolves around scraping the flocculated material on the electrocoagulation electrode column 2026, with the transmission pulley 2071, which is rotatably mounted on the transmission limiting sleeve 2028, serving as the starting point for power transmission. When the transmission sleeve 2019 rotates, it drives the transmission pulley 2071 to rotate around the transmission limiting sleeve 2028 via belt transmission. The transmission pulley 2071 then drives the bidirectional threaded screw 2072, which is fixed thereto, to rotate synchronously. Since the bidirectional threaded screw 2072 is bidirectionally threaded, the scraping ring moving seat 2076, which is threaded on its outer circumference, will move axially with the rotation of the bidirectional threaded screw 2072. When the scraping ring moving seat 2076 moves, the multiple transmission balls 2074 in the mounting groove will move. Force is transmitted to the flocculation scraping ring 2075, causing the flocculation scraping ring 2075 to move axially synchronously with the scraping ring moving seat 2076. At the same time, the flocculation scraping ring 2075 can rotate freely relative to the scraping ring moving seat 2076 with the help of ball bearings. During this process, the spline on the inner wall of the flocculation scraping ring 2075 is always in contact with the flower groove on the outer wall of the electrocoagulation electrode column 2026. It rotates synchronously with the electrocoagulation electrode column 2026 and moves smoothly along its axis. It achieves reciprocating motion in conjunction with the bidirectional thread characteristics of the bidirectional threaded screw 2072. The moving limit block 2073 limits the movement range of the scraping ring moving seat 2076, ensuring that the flocculation scraping ring 2075 can completely scrape the flocculated material on the surface of the electrocoagulation electrode column 2026.

[0070] Furthermore, it also includes a funnel-shaped drain pipe 204 disposed on the outer wall of the processing chamber housing 2021. The funnel-shaped drain pipe 204 is fixedly installed on the outer periphery of the processing chamber housing 2021 by multiple drain pipe fixing brackets 203. The funnel-shaped drain pipe 204 is funnel-shaped with the opening gradually decreasing from high to low along the height direction. The funnel-shaped drain pipe 204 is open at both the top and bottom. The larger diameter opening of the funnel-shaped drain pipe 204 is interconnected with the internal space of the processing chamber housing 2021. Multiple drain pipe support brackets 205 for support are evenly provided along the axis on the outer wall of the funnel-shaped drain pipe 204.

[0071] Furthermore, the upper end face of the processing chamber housing 2021 is provided with a raw material injection port 2027 that communicates with the internal space of the processing chamber housing 2021. The raw material injection port 2027 is used to inject raw materials into the processing chamber housing 2021. The processing chamber housing 2021 is also provided with an alarm light 206 for alarm purposes.

[0072] The funnel-shaped drain pipe 204 is fixedly installed on the outer periphery of the processing chamber shell 2021 by multiple drain pipe fixing brackets 203. Multiple drain pipe support brackets 205 evenly distributed on the outer wall provide stable support for the funnel-shaped drain pipe 204, ensuring that its funnel-shaped structure is stably upright. The funnel-shaped drain pipe 204 has openings at the top and bottom, and the openings gradually narrow from high to low along the height direction. The larger diameter opening is connected to the internal space of the processing chamber shell 2021. When the processing chamber shell 2021 is used for filtration or other treatments, the funnel-shaped drain pipe 204 can guide the flow of materials through the funnel shape, which not only facilitates the discharge of the treated material from the lower small opening in the processing chamber shell 2021, but also forms a smooth material circulation path with the internal space of the processing chamber shell 2021.

[0073] The raw material inlet 2027 on the upper end face of the treatment chamber shell 2021 serves as a raw material injection channel, allowing for the precise injection of the raw materials required for treatment into the treatment chamber shell 2021. After entering, the raw materials mix with the wastewater awaiting treatment, providing a material basis for subsequent filtration, flocculation, and other processes. Simultaneously, the alarm light 206 on the treatment chamber shell 2021 monitors the equipment's operating status in real time. When there is insufficient raw material, processing abnormalities, or component failures, the alarm light 206 triggers an alarm, promptly alerting the operator to intervene and ensuring the stable operation of the overall treatment process.

[0074] In summary, the electrocoagulation electrode column 2026, as the core component of electrocoagulation, undergoes an electrochemical reaction when the electrode plates within the flower-shaped grooves on its outer wall are energized. This reaction destabilizes suspended particles, colloids, and other substances in drilling mud wastewater, causing them to aggregate and form flocs. Simultaneously, the electrocoagulation electrode column 2026 rotates under the driving force provided by the drive component 201, accelerating the contact between the wastewater and the electrode and improving flocculation efficiency.

[0075] The drive assembly 201 provides power to the entire device, with the drive output shaft 2012 serving as the power output component, driving the transmission sleeve 2019 and other components to move via the mounting section. The power switching control assembly is responsible for power switching. When the electromagnet at the bottom of the sliding groove of the switching base 2081 is energized, it generates a magnetic force with the permanent magnet at the bottom of the switching slider 2082, pushing the switching slider 2082 to slide. This causes positioning blocks one and two to engage with positioning holes one and two, respectively, achieving a transmission connection between the drive assembly 201 and the flocculation filter assembly 202. Simultaneously, the electroflocculation electrode column 2026 is energized. When the electromagnet is de-energized, the switching slider 2082 resets, the drive assembly 201 is disconnected from the flocculation filter assembly 202, the electroflocculation electrode column 2026 is de-energized, and a transmission connection can then be established with the flocculation scraping assembly 207.

[0076] When the electrocoagulation electrode post 2026 drives the transmission turntable 2025 to rotate, the second convex ball at the lower end of the transmission turntable 2025 makes alternating contact with the first convex ball on the filter plate 2022, pushing the filter plate 2022 to slide along the filter plate slide rail 2024. The filter holes on the filter plate 2022 can separate the flocculated material from the water. At the same time, the connecting shaft at the bottom of the transmission turntable 2025 drives the filter plate scraper 2023 to rotate, and the filter plate scraper 2023 scrapes the surface of the filter plate 2022 to prevent the filter holes from being blocked by flocculated material.

[0077] The flocculation scraping assembly 207 is connected to the transmission sleeve 2019 via a belt. The transmission sleeve 2019 drives the transmission pulley 2071 to rotate, which in turn causes the bidirectional threaded screw 2072 to rotate. Because the bidirectional threaded screw 2072 has a bidirectional thread, its rotation causes the scraping ring moving seat 2076 to move axially. The scraping ring moving seat 2076 drives the flocculation scraping ring 2075 to move axially synchronously via the transmission balls 2074, and the flocculation scraping ring 2075 can rotate relative to the scraping ring moving seat 2076. The splines on the inner wall of the flocculation scraping ring 2075 fit into the flower-shaped grooves on the outer wall of the electrocoagulation electrode column 2026, causing it to rotate synchronously with the electrocoagulation electrode column 2026 while reciprocating axially, thereby completely scraping away the flocculated material on the surface of the electrocoagulation electrode column 2026. The moving limit block 2073 restricts the movement range of the scraping ring moving seat 2076.

[0078] Specifically, the installation and operation frame 100 serves as the installation space and personnel operation platform, providing basic support for the destabilization and separation main body 200. Operators inject the drilling mud waste material to be processed into the processing chamber housing 2021 through the raw material injection port 2027 at the upper end of the processing chamber housing 2021. The drain pipe support frame 205 supports the funnel-shaped drain pipe 204, ensuring the stability of the funnel-shaped structure of the drain pipe 204. The power switching control component performs the switching first. The electromagnet at the bottom of the sliding groove of the switching base 2081 is energized, interacting with the permanent magnet of the switching slider 2082, pushing the switching slider 2082 to slide. This causes the positioning block one of the upper positioning plate 2083 to engage with the positioning hole one of the internal gear transmission ring 2017, and the positioning block two of the lower positioning plate 2084 to engage with the positioning hole two of the upper triangular transmission frame 2013. The drive component 201 establishes a transmission connection with the flocculation and filtration component 202, while the electrode plates of the electrocoagulation electrode column 2026 are energized. The drive assembly 201 starts working, the drive mounting base 2011 provides the installation foundation, the drive output shaft 2012 rotates, the installation section drives the transmission sleeve 2019 to move, the transmission sleeve 2019 drives the internal gear transmission ring 2017 to rotate through the fixed connecting rod 2018, the internal gear transmission ring 2017 meshes with the transmission connecting rod 2015, driving the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016 to move synchronously on the smooth section one and smooth section two respectively, the limiting and stabilizing sleeve 2014 plays a limiting and stabilizing role, the electrocoagulation electrode column 2026 rotates under the drive of the installation section, and performs flocculation treatment on the substances in the wastewater by electrocoagulation. Subsequently, the transmission turntable 2025 rotates with the electrocoagulation electrode column 2026, and its convex ball pushes the filter plate 2022 to slide along the filter plate slide rail 2024. The filter holes of the filter plate 2022 separate the flocculated material from the water. The filter plate scraper 2023 simultaneously scrapes the surface of the filter plate 2022, and the separated water is discharged through the lower opening of the funnel-shaped drain pipe 204.

[0079] When the power switching control component switches again, the electromagnet is de-energized, the switching slider 2082 is reset, the positioning block one and the positioning block two are disengaged from the positioning hole one and the positioning hole two respectively, the drive component 201 is disconnected from the flocculation filter component 202, and at the same time the electrode plate of the electrocoagulation electrode column 2026 is de-energized, and the drive component 201 is connected to the flocculation scraping component 207.

[0080] The drive assembly 201 provides driving force to the flocculation and scraping assembly 207. The transmission sleeve 2019 drives the transmission pulley 2071 to rotate via belt drive. The transmission pulley 2071 drives the bidirectional threaded screw 2072 to rotate. The scraping ring moving seat 2076 moves axially along the bidirectional threaded screw 2072, and drives the flocculation and scraping ring 2075 to move axially synchronously via the transmission ball bearings 2074. The flocculation and scraping ring 2075 reciprocates along its axial direction while rotating synchronously with the electrocoagulation electrode column 2026, completely scraping away the flocculated material on the surface of the electrocoagulation electrode column 2026. The moving limit block 2073 limits the movement range of the scraping ring moving seat 2076. Through the continuous switching of the power switching control assembly, the alternating cycle of flocculation treatment and flocculation scraping processes is realized. The alarm light 206 on the processing chamber housing 2021 monitors the equipment operating status in real time. When there is insufficient raw material, processing abnormality, or component failure, an alarm is issued in a timely manner to prompt the operator to intervene.
