Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dredging machinery, and more particularly relates to a drilling mud waste destabilization and separation device using an electrocoagulation method. BACKGROUND

[0002] During drilling operations, a large amount of drilling mud waste containing suspended particles, colloids and other pollutants will be generated. If it is directly discharged, it will cause environmental pollution, so it needs to be destabilized and separated. The electrocoagulation technology is widely used in the destabilization and separation of drilling mud waste due to its high efficiency and no secondary pollution. The core principle is that the electrochemical reaction generated by the power supply of the electrode plate makes the suspended particles and colloids in the sewage lose stability and aggregate into floc, and then realizes solid-liquid separation.

[0003] However, the existing electrocoagulation destabilization and separation device still has many deficiencies in actual application.

[0004] On the one hand, the problem of floc accumulation on the surface of the electrode plate is prominent. During the electrocoagulation reaction process, the pollutants in the sewage will continuously aggregate into floc on the surface of the electrode plate. If it is not removed in time, the floc will gradually cover the active area of the electrode, resulting in a significant reduction in the effective contact area between the electrode and the sewage, a significant reduction in the electrochemical reaction rate, and ultimately a reduction in the floc efficiency. The existing device has defects in solving this problem: manual periodic cleaning needs frequent shutdown, which not only interrupts the processing process and increases labor intensity, but also causes the processing cycle to be prolonged due to shutdown; the fixed scraping structure is difficult to adapt to the dynamic reaction process of the electrode plate, the scraping range is limited, and local floc residues are easy to occur, which reduces the processing efficiency after long-term operation.

[0005] On the other hand, the attachment of bubbles on the surface of the electrode plate hinders the reaction. During the electrocoagulation process, electrolysis reaction occurs when the electrode plate is powered on, generating a large amount of hydrogen, oxygen and other bubbles. These bubbles are easy to adsorb on the surface of the electrode plate to form a gas film. This gas film significantly increases the contact resistance between the electrode and the sewage, reduces the current efficiency, and hinders the migration of the treated substances in the sewage to the electrode surface, resulting in uneven and insufficient floc reaction, which not only prolongs the processing time, but also causes the water quality to fluctuate, making it difficult to meet the process requirements of stable processing. At present, the existing device lacks a targeted bubble removal mechanism and cannot effectively solve the negative effects caused by bubble attachment.

[0006] Therefore, a drilling mud waste destabilization and separation device using an electrocoagulation method is proposed. SUMMARY

Through the switching control of the power switching control assembly, the flocculation treatment and the flocculation scraping process are alternately performed.

[0053] Further, the driving assembly 201 comprises a driving mounting seat 2011, and a driving output shaft 2012 is fixedly arranged at the top of the inner wall of the driving mounting seat 2011. The output end of the driving output shaft 2012 is divided into three sections, which are a smooth section one, a flat shaft section, a smooth section two and a mounting section from top to bottom.

[0054] The flat shaft section of the driving output shaft 2012 is fixedly sleeved with a limiting stable sleeve 2014. The smooth section one of the driving output shaft 2012 is sleeved with an upper triangular transmission frame 2013, and the smooth section two is sleeved with a lower triangular transmission frame 2016. The top projections of the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016 are coincident with each other and comprise but are not limited to an equilateral triangle. A plurality of transmission connecting rods 2015 are equidistantly arranged between the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016, including but not limited to three. The three transmission connecting rods 2015 are uniformly distributed at the three corners of the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016, and are rotationally connected to the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016.

[0055] The mounting section of the driving output shaft 2012 is sleeved with a transmission sleeve 2019.

An inner tooth ring is arranged on the inner peripheral surface of the inner tooth transmission ring 2017. The inner tooth transmission ring 2017 is engaged with the three transmission connecting rods 2015 through the inner tooth ring. One end of the mounting section away from the smooth section two is fixedly connected with one end of the electric flocculation electrode column 2026.

[0056] A plurality of positioning holes one are evenly arranged on the inner tooth transmission ring 2017 along the axis, and a plurality of positioning holes two are evenly arranged on the upper triangular transmission frame 2013 along the axis;

[0057] When the driving assembly 201 is working, the driving mounting seat 2011 provides a mounting base, the driving output shaft 2012 fixed at the top of the inner wall serves as a power output component, the mounting section drives the transmission sleeve 2019 to move synchronously, the transmission sleeve 2019 drives the inner tooth transmission ring 2017 to rotate through a plurality of fixed connecting rods 2018, the inner tooth transmission ring 2017 drives the upper triangular transmission frame 2013 to move synchronously on the smooth section one and the lower triangular transmission frame 2016 to move synchronously on the smooth section two through the meshing of the inner tooth ring and the three transmission connecting rods 2015, the three transmission connecting rods 2015 are respectively connected to the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016 and are evenly distributed at the corners of the two, the driving output shaft 2012 on the flat section drives the limiting and stabilizing sleeve 2014 to limit and stabilize, the end of the mounting section away from the smooth section two drives the electrocoagulation electrode column 2026 to move, and the positioning holes one of the inner tooth transmission ring 2017 and the positioning holes two of the upper triangular transmission frame 2013 can realize the switching of positioning in cooperation with the power switching control assembly during the movement;

[0058] Further, the coagulation and filtration assembly 202 includes a transmission limiting sleeve 2028 sleeved on the outer periphery of the transmission sleeve 2019 and used for limiting the transmission sleeve 2019, a treatment cavity shell 2021 is sleeved on the outer shaft of the transmission limiting sleeve 2028, a through groove is symmetrically arranged on the inner wall of the treatment cavity shell 2021, two filter plate sliding rails 2024 are fixedly arranged in the two through grooves, a filter plate 2022 is slidably arranged on the two filter plate sliding rails 2024, a plurality of filter holes are evenly arranged on the filter plate 2022, and a plurality of convex balls one are evenly arranged on the upper surface of the filter plate 2022 along the axis;

[0059] The electrocoagulation electrode column 2026 is fixedly provided with a transmission turntable 2025 at the end away from the transmission sleeve 2019, a plurality of convex balls two are evenly arranged on the lower end surface of the transmission turntable 2025 along the axis, and the convex balls one and the convex balls two are staggered distributed in normal state;

[0060] The bottom end center of the transmission turntable 2025 is fixedly provided with a connecting shaft, the connecting shaft passes through the filter plate 2022 at the end away from the transmission turntable 2025, and the penetrating end is fixedly provided with a filter plate scraping brush 2023 used for scraping the filter plate 2022;

[0061] The transmission limiting sleeve 2028 is sleeved on the outer periphery of the transmission sleeve 2019 to limit the position of the transmission sleeve 2019, thereby providing a stable basis for the operation of subsequent components. The processing cavity shell 2021 is sleeved on the outer shaft of the transmission limiting sleeve 2028, and the inner wall of the processing cavity shell 2021 is symmetrically provided with a through groove in which a filter plate sliding rail 2024 is fixed. The filter plate 2022 is arranged on the two filter plate sliding rails 2024 and can slide along the filter plate sliding rails 2024.

[0062] When the electrocoagulation electrode column 2026 rotates away from the end of the transmission sleeve 2019, the transmission disc 2025 fixed thereto rotates synchronously. The convex ball two on the lower end surface of the transmission disc 2025 rotates, and because the convex ball two and the convex ball one on the upper end surface of the filter plate 2022 are staggered in distribution under normal circumstances, the convex ball two interacts with the convex ball one during rotation to push the filter plate 2022 to slide along the filter plate sliding rail 2024.

[0063] When the filter plate 2022 slides, the filter holes formed in the filter plate 2022 operate synchronously to separate and filter the coagulation and flocculation substances in the sewage from the water. At the same time, the connecting shaft at the bottom center of the transmission disc 2025 rotates with the transmission disc 2025. The end of the connecting shaft away from the transmission disc 2025 penetrates through the filter plate 2022, and the filter plate scraper 2023 fixed on the outer periphery of the penetrating end also rotates. During the filtering operation of the filter plate 2022, the filter plate scraper 2023 continuously scrapes the surface of the filter plate 2022 to prevent the coagulation and flocculation substances from blocking the filter holes.

[0064] Further, the power switching control assembly includes a switching base 2081 fixed on the transmission limiting sleeve 2028. The power switching control assembly is located in the space of the driving mounting seat 2011. The switching base 2081 is provided with a sliding groove, and a switching sliding block 2082 is slidably arranged in the sliding groove. The switching sliding block 2082 is provided with an upper positioning plate 2083 and a lower positioning plate 2084 fixed in sequence from top to bottom along the height direction on the side away from the switching base 2081. The proximal sides of the upper positioning plate 2083 and the lower positioning plate 2084 are respectively provided with a first positioning block and a second positioning block. The first positioning block and the second positioning block are respectively used for cooperating with the first positioning hole and the second positioning hole.

[0065] The bottom end of the sliding groove of the switching base 2081 is provided with an electromagnet, and the bottom end of the switching sliding block 2082 located in the sliding groove is provided with a permanent magnet. The electrode sheet on the electrocoagulation electrode column 2026 is electrically connected to the electromagnet. When the electromagnet is powered on, the electrode sheet is also powered on.

[0066] The power switching control assembly is installed on the switching base 2081 fixed on the transmission limiting sleeve 2028, and is located in the space of the driving mounting seat 2011. The working process is as follows: when positioning cooperation is needed, the electromagnet at the bottom end of the switching groove of the switching base 2081 is powered on, and the electrode sheet on the electrode column 2026 is powered on at the same time due to the electrical connection between the electromagnet and the electrode sheet on the electrode column 2026. After the electromagnet is powered on, the permanent magnet at the bottom end of the switching sliding block 2082 in the switching groove generates a magnetic force, which pushes the switching sliding block 2082 to slide along the switching groove of the switching base 2081. The upper positioning plate 2083 and the lower positioning plate 2084 on the side of the switching sliding block 2082 away from the switching base 2081 move synchronously, so that the positioning block one on the upper positioning plate 2083 corresponds to the positioning hole one of the inner tooth 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, thereby completing the positioning action. When positioning is not needed, the electromagnet is powered off, and the electrode sheet on the electrode column 2026 is also powered off at the same time. The switching sliding block 2082 is reset along the switching groove under the action of its own gravity or the reverse force of the permanent magnet and the electromagnet. The positioning block one and the positioning block two are separated from the positioning hole one and the positioning hole two respectively, and the initial state is restored.

[0067] Further, the coagulation and flocculation scraping assembly 207 includes a transmission belt pulley 2071 rotatably arranged on the transmission limiting sleeve 2028. The transmission belt pulley 2071 is connected with the transmission sleeve 2019 through a belt transmission. A double-thread screw rod 2072 is fixedly arranged at one end of the transmission belt pulley 2071 away from the transmission limiting sleeve 2028.

A spline is arranged on the inner wall of the coagulation and flocculation scraping ring 2075 and matched with the pattern groove.

[0069] The working of the flocculus scraping assembly 207 is around the scraping of the flocculus on the electrocoagulation electrode column 2026, and the rotation of the transmission belt pulley 2071 installed on the transmission limiting sleeve 2028 is the starting point of power transmission. When the transmission sleeve 2019 is running, the transmission belt pulley 2071 is driven to rotate around the transmission limiting sleeve 2028 through the belt transmission, and the bidirectional threaded rod 2072 fixed with the transmission belt pulley 2071 is synchronously rotated. Since the bidirectional threaded rod 2072 is provided with bidirectional threads, the scraping ring moving seat 2076 sheathed on the outer periphery of the threads will move axially along with the rotation of the bidirectional threaded rod 2072. When the scraping ring moving seat 2076 moves, the plurality of transmission balls 2074 in the installation groove will transmit power to the flocculus scraping ring 2075, so that the flocculus scraping ring 2075 moves axially synchronously with the scraping ring moving seat 2076, and the flocculus scraping ring 2075 can rotate freely relative to the scraping ring moving seat 2076 by means of the balls. In this process, the spline on the inner wall of the flocculus scraping ring 2075 is always matched with the flower-shaped groove on the outer wall of the electrocoagulation electrode column 2026, which rotates synchronously with the electrocoagulation electrode column 2026 and moves stably along the axial direction. The bidirectional threaded rod 2072 realizes reciprocating motion by cooperating with the bidirectional threaded characteristic, and the movement limiting block 2073 limits the movement range of the scraping ring moving seat 2076, so that the flocculus scraping ring 2075 can completely scrape the flocculus on the surface of the electrocoagulation electrode column 2026.

[0070] Further, the funnel-shaped liquid discharge pipe 204 is arranged on the outer wall of the treatment cavity shell 2021, and the funnel-shaped liquid discharge pipe 204 is fixedly installed on the outer periphery of the treatment cavity shell 2021 through a plurality of liquid discharge pipe fixing frames 203. The funnel-shaped liquid discharge pipe 204 is funnel-shaped with the opening gradually decreasing from high to low along the height direction. The funnel-shaped liquid discharge pipe 204 is open at the top and the bottom, and the large-diameter opening of the funnel-shaped liquid discharge pipe 204 is in communication with the internal space of the treatment cavity shell 2021. A plurality of liquid discharge pipe support frames 205 are uniformly arranged on the outer wall of the funnel-shaped liquid discharge pipe 204 along the axis for supporting.

[0071] Further, the upper end surface of the treatment cavity shell 2021 is provided with a raw material injection port 2027 in communication with the internal space of the treatment cavity shell 2021. The raw material injection port 2027 is used for injecting raw materials into the treatment cavity shell 2021. The treatment cavity shell 2021 is also provided with an alarm lamp 206 for alarm.

[0072] The funnel-shaped liquid discharge pipe 204 is fixedly installed on the outer periphery of the treatment cavity shell 2021 through a plurality of liquid discharge pipe fixing frames 203, and a plurality of liquid discharge pipe support frames 205 uniformly distributed on the outer wall provide stable support for the funnel-shaped liquid discharge pipe 204, so as to ensure that the funnel-shaped structure is stably erected. The funnel-shaped liquid discharge pipe 204 is open upward and downward, and the opening along the height direction gradually decreases from high to low. The opening with a larger diameter is in communication with the internal space of the treatment cavity shell 2021. When the treatment cavity shell 2021 is internally treated, such as filtering, the funnel-shaped liquid discharge pipe 204 can guide the material flow through the funnel shape, which not only facilitates the discharge of the treated material from the lower small opening of the treatment cavity shell 2021, but also forms a smooth material circulation path in cooperation with the internal space of the treatment cavity shell 2021.

[0073] The raw material injection port 2027 on the upper end surface of the treatment cavity shell 2021 serves as a raw material injection channel, and can accurately inject the raw material required for treatment into the treatment cavity shell 2021. After the raw material enters, it is mixed with the sewage to be treated, thereby providing a material basis for subsequent filtering, flocculation and other links. At the same time, the alarm lamp 206 on the treatment cavity shell 2021 monitors the equipment operation state in real time. When there is a shortage of raw materials, abnormal treatment or component failure, etc., the alarm lamp 206 triggers an alarm to prompt the operator to intervene in time, thereby ensuring the stable operation of the overall treatment process.

[0074] In summary, when the electrode sheets in the patterned groove on the outer wall of the electrocoagulation electrode column 2026 are powered on, an electrochemical reaction occurs. This reaction can make the suspended particles, colloids and other substances in the drilling mud sewage lose stability, and aggregate to form flocculation. At the same time, the electrocoagulation electrode column 2026 rotates under the driving force provided by the driving assembly 201, which can accelerate the contact between the sewage and the electrode and improve the flocculation efficiency.

[0075] The driving assembly 201 provides power for the entire device. The driving output shaft 2012 serves as a power output component and drives the transmission sleeve 2019 and other components through the installation section. The power switching control assembly is responsible for power switching. When the electromagnet at the bottom end of the switching base 2081 is powered on, it generates a magnetic force with the permanent magnet at the bottom end of the switching slider 2082, pushes the switching slider 2082 to slide, and makes the positioning block one and the positioning block two cooperate with the positioning hole one and the positioning hole two respectively, so as to realize the transmission connection between the driving assembly 201 and the flocculation and filtration assembly 202, and the electrocoagulation electrode column 2026 is powered on. When the electromagnet is powered off, the switching slider 2082 is reset, the driving assembly 201 is disconnected from the flocculation and filtration assembly 202, the electrocoagulation electrode column 2026 is powered off, and then the transmission connection between the electrocoagulation electrode column 2026 and the flocculation scraping assembly 207 can be established.

[0076] When the transmission disc 2025 is driven to rotate by the electrocoagulation electrode column 2026, the convex ball two at the lower end of the transmission disc 2025 is in staggered contact with the convex ball one on the filter plate 2022, and the filter plate 2022 is pushed to slide along the filter plate slide rail 2024. The filter holes on the filter plate 2022 can separate the flocculation material from the water, and at the same time, the connecting shaft at the bottom end of the transmission disc 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 the flocculation material.

[0077] The flocculation scraping assembly 207 is in transmission connection with the transmission sleeve 2019 through a belt, the transmission sleeve 2019 drives the transmission belt pulley 2071 to rotate, and then drives the bidirectional threaded screw rod 2072 to rotate. Since the bidirectional threaded screw rod 2072 is bidirectional threaded, its rotation will make the scraping ring moving seat 2076 move axially, the scraping ring moving seat 2076 drives the flocculation scraping ring 2075 to move axially synchronously through the transmission ball 2074, and the flocculation scraping ring 2075 can rotate relative to the scraping ring moving seat 2076. The spline on the inner wall of the flocculation scraping ring 2075 is in engagement with the flower-shaped groove on the outer wall of the electrocoagulation electrode column 2026, so that it rotates synchronously with the electrocoagulation electrode column 2026 while reciprocating axially, thereby fully scraping the flocculation material on the surface of the electrocoagulation electrode column 2026, and the movement limiting block 2073 limits the movement range of the scraping ring moving seat 2076.

[0078] Specifically, the installation operation frame 100 is installed as an installation space and a personnel operation platform, and provides a basic support for the unstable separation main body 200. The operator injects the drilling mud waste raw material to be treated into the processing cavity shell 2021 through the raw material injection port 2027 at the upper end of the processing cavity shell 2021. The liquid discharge pipe support frame 205 supports the funnel-shaped liquid discharge pipe 204, and ensures the stability of the funnel-shaped structure of the funnel-shaped liquid discharge pipe 204. The power switching control assembly is switched first. The electromagnet at the bottom end of the switching base 2081 is electrified, interacts with the permanent magnet of the switching slider 2082, pushes the switching slider 2082 to slide, makes the positioning block one of the upper positioning plate 2083 match the positioning hole one of the inner tooth transmission ring 2017, makes the positioning block two of the lower positioning plate 2084 match the positioning hole two of the upper triangular transmission frame 2013, establishes a transmission connection between the driving assembly 201 and the flocculation and filtration assembly 202, and the electrode sheet of the electrocoagulation electrode column 2026 is electrified. The driving assembly 201 starts to work, the driving mounting seat 2011 provides an installation base, the driving output shaft 2012 operates, the installation section drives the transmission sleeve 2019 to move, the transmission sleeve 2019 drives the inner tooth transmission ring 2017 to rotate through the fixed connecting rod 2018, the inner tooth transmission ring 2017 engages the transmission connecting rod 2015, drives the upper triangular transmission frame 2013 and the lower triangular transmission frame 2016 to move synchronously on the smooth section one and the smooth section two respectively, and the limiting and stabilizing sleeve 2014 plays a limiting and stabilizing role. The electrocoagulation electrode column 2026 rotates under the driving of the installation section, and the substances in the sewage are treated by electrocoagulation flocculation. Subsequently, the transmission turntable 2025 rotates with the electrocoagulation electrode column 2026, the convex ball two pushes the filter plate 2022 to slide along the filter plate slide rail 2024, the filter holes of the filter plate 2022 separate the coagulation and flocculation substances from the water, the filter plate scraper 2023 synchronously scrapes the surface of the filter plate 2022, and the separated water is discharged through the lower opening of the funnel-shaped liquid discharge pipe 204.

[0079] The power switching control assembly is switched again. The electromagnet is de-energized, the switching slider 2082 is reset, the positioning block one and the positioning block two are respectively separated from the positioning hole one and the positioning hole two, the driving assembly 201 and the flocculation and filtration assembly 202 are disconnected, the electrode sheet of the electrocoagulation electrode column 2026 is de-energized, and the driving assembly 201 and the coagulation and flocculation scraping assembly 207 are connected.

[0080] The driving assembly 201 provides driving force for the coagulation and floc scraping assembly 207. The transmission sleeve 2019 drives the transmission belt wheel 2071 through the belt transmission, the transmission belt wheel 2071 drives the bidirectional threaded rod 2072 to rotate, the scraping ring moving seat 2076 moves along the bidirectional threaded rod 2072 in the axial direction, the transmission ball 2074 drives the coagulation and floc scraping ring 2075 to move synchronously in the axial direction, the coagulation and floc scraping ring 2075 rotates synchronously with the electrocoagulation electrode column 2026 while reciprocating in the axial direction, and the coagulation and floc on the surface of the electrocoagulation electrode column 2026 is scraped off comprehensively. The movement limiting block 2073 limits the movement range of the scraping ring moving seat 2076. Through the continuous switching of the power switching control assembly, the coagulation treatment and the floc scraping process are alternately cycled. The alarm lamp 206 on the treatment cavity shell 2021 monitors the equipment operation state in real time. When there is insufficient raw material, abnormal treatment or component failure, etc., an alarm is sent in time to prompt the operator to intervene.
