Description

Technical Field

[0001] This invention relates to the field of wastewater separation and treatment technology, specifically to a treatment device and method for separating high-salt, high-concentration organic wastewater. Background Technology

[0002] High-salinity wastewater, as one of the major types of industrial wastewater, has gradually attracted the attention of scholars and practitioners in the field of water treatment due to its wide range of sources, high hazard, and high recyclability. Treatment methods mainly include physicochemical and biological methods. Physicochemical methods include distillation, reverse osmosis, electrodialysis, and electrocoagulation. Given my country's vast saline soil and brine resources, halophilic microorganisms are widely present. With the development of cultivation technology, their isolation and cultivation are relatively easy. These halophilic bacteria can utilize many organic substances (including recalcitrant and toxic substances) as their carbon or nitrogen sources. Therefore, using halophilic bacteria to treat high-salinity organic wastewater has broad prospects and is of great significance for both practical applications and theoretical research. Constructing a halophilic microbial agent system for the treatment of high-salinity wastewater makes it possible to achieve efficient biodegradation of organic pollutants in high-salinity wastewater. High-salinity wastewater can be filtered, separated, and desalinated using nanofiltration membranes and reverse osmosis membranes. The treated low-salinity "clean water" can then be recovered and reused. Furthermore, waste salt in high-salinity wastewater can be recovered and treated using evaporation and crystallization technology, aiming to achieve "zero discharge" or "near-zero discharge" of high-salinity wastewater. However, existing wastewater separation and treatment devices have the following problems in use: Existing wastewater separation and treatment devices introduce treated wastewater into the separation equipment for filtration and separation. However, they lack an effective pre-dispersion structure and are mostly flow-type filtration separation devices. When there is agglomeration in the wastewater, it affects the natural filtration effect and easily causes blockage. At the same time, after filtration, due to the integrated design of the separation and treatment device, the residues on the internal filter layer are difficult to clean, affecting subsequent continuous operation.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0004] The purpose of this invention is to provide a treatment device and method for separating high-salt, high-concentration organic wastewater, in order to solve the problems mentioned in the background art. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a treatment device and method for separating high-salt, high-concentration organic wastewater, comprising a body, wherein a motor is fixed on the top of the body and a membrane separation cylinder is fixed on the inner wall of the body; It also includes a limiting telescopic rod, which is connected to the bottom of the motor. The bottom of the limiting telescopic rod is connected to a mounting plate. A central shaft is embedded in the bottom of the mounting plate and slidably mounted. A scraper is fixed to the outside of the central shaft. The scraper is located above the membrane separation cylinder. A receiving plate is sleeved on the central shaft through a telescopic component. The receiving plate is located on the lower end face of the opening in the middle of the membrane separation cylinder. A positioning ring is nested in the cavity at the top edge of the receiving plate. The positioning ring is fixed to the lower end face of the membrane separation cylinder. An electromagnet is fixed to the outside of the positioning ring. A push component is disposed between the inner side of the top of the machine body and the installation plate, and is used to adjust the position of the installation plate; A material discharge assembly is disposed within a receiving tray and is used for sealing the receiving tray and discharging material.

[0006] Preferably, the membrane separation cylinder is designed as a hollow cone structure, and the membrane separation cylinders are vertically and equally spaced within the machine body. Nanofiltration membranes or reverse osmosis membranes are used inside the membrane separation cylinders.

[0007] Preferably, the outer side of the scraper is configured with an inclined structure, the scraper is parallel to the inclined surface of the membrane separation cylinder, and the scraper is not in contact with the membrane separation cylinder at its initial position.

[0008] Preferably, the positioning ring slides within the cavity at the top of the receiving plate, and the inner wall of the cavity at the top of the receiving plate is magnetically attracted by an electromagnet using a magnetic material.

[0009] Preferably, the telescopic component includes a first guide head and a first guide groove. The first guide head is fixed to the outside of the central shaft, and the outer end of the first guide head is slidably disposed in the first guide groove. The first guide groove is formed on the hollow sidewall in the middle of the receiving plate, and the first guide groove is distributed in a spiral structure.

[0010] Preferably, the pushing assembly includes an electric push rod and a push plate. The electric push rod is fixed inside the top of the machine body, and the bottom output end of the electric push rod is connected to the push plate. The push plate is connected to the outside of the mounting plate through a bearing.

[0011] Preferably, the material leakage assembly includes a material leakage plate, which is embedded and rotatably installed inside the cavity of the receiving plate. The material leakage plate and the receiving plate are respectively provided with a first material leakage hole and a second material leakage hole. A second guide groove is provided on the outer side of the material leakage plate, and a second guide head is provided in the second guide groove. The second guide head is fixed on the inner wall of the positioning ring.

[0012] Preferably, the first and second leakage holes are distributed at equal angles on the leakage plate and the receiving plate, respectively. Both the first and second leakage holes are configured as fan-shaped structures, and their initial positions are staggered.

[0013] Preferably, the second guide head slides in contact with the second guide groove, and the second guide groove is designed as a spiral structure.

[0014] Preferably, the method includes the following steps: S1: The high-salt, high-concentration organic wastewater to be treated is injected into the equipment through the feed pipe at the top of the machine, and the wastewater is separated and filtered through the membrane separation cylinder; S2: Start the motor. The motor drives the mounting plate and the central shaft to rotate through the limit telescopic rod. The first guide head slides along the spiral first guide groove on the hollow side wall in the middle of the receiving plate, driving the central shaft to move up and down synchronously. The scraper rotates with the central shaft and moves up and down to break up the aggregated impurities in the wastewater. S3: After filtration, cleaning water is injected into the machine body through the external pipeline, the electromagnet is turned off, the adsorption and fixation of the receiving plate is released, and the electric push rod drives the mounting plate and the central shaft to move down through the push plate, so that the scraper sticks to the top surface of the membrane separation cylinder. S4: The receiving plate moves up and down on the positioning ring, causing the material leakage plate to rotate, so that the first material leakage hole and the second material leakage hole coincide. The motor drives the central shaft to rotate again, scraping off the impurities on the membrane separation cylinder and discharging them through the first and second material leakage holes for impurity cleaning.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, during the filtration stage, the scraper is located above the membrane separation cylinder. The motor drives the mounting plate and the central shaft to rotate reciprocally via the limiting telescopic rod, which in turn drives the scraper to rotate. At the same time, the position of the receiving plate is restricted by the electromagnet, so that under the action of the first guide head and the first guide groove, the central shaft moves up and down synchronously during the rotation, thereby driving the scraper to rotate and move up and down. This breaks up the agglomerates in the wastewater, ensuring the smoothness of subsequent filtration and avoiding blockage during the filtration process. In this invention, during the cleaning stage, an electric push rod and push plate drive the mounting plate downwards. Simultaneously, the electromagnet is de-energized, releasing the fixing of the receiving plate. This allows the receiving plate to move downwards under gravity. On one hand, this causes the scraper on the central shaft to move down to the top surface of the membrane separation cylinder. On the other hand, as the receiving plate moves downwards, it drives the material leakage plate to rotate via the second guide groove and the second guide head. This causes the first leakage hole on the material leakage plate to coincide with the second leakage hole on the receiving plate. This releases the position of the receiving plate and frees up space at the bottom of the membrane separation cylinder. The receiving plate itself also facilitates material leakage. At this point, the central shaft rotates back and forth again, only causing the scraper to rotate on the membrane separation cylinder, scraping off impurities for easy cleaning and facilitating subsequent continuous separation operations. This invention solves the agglomeration problem with the scraper and also achieves the cleaning function. The overall structure is simple, does not obstruct the internal separation space, and is highly practical. Attached Figure Description

The membrane separation cylinder 3 is designed as a hollow cone structure. The membrane separation cylinders 3 are vertically and equally spaced inside the body 1. Nanofiltration membranes or reverse osmosis membranes are used inside the membrane separation cylinders 3. Wastewater is introduced into the machine body 1 through the feed pipe.

The bottom of the mounting plate 5 is embedded with a central shaft 6 for limiting sliding installation. A scraper 61 is fixed on the outside of the central shaft 6. The scraper 61 is located above the membrane separation cylinder 3. A receiving plate 7 is sleeved on the central shaft 6 through a telescopic component. The receiving plate 7 is located on the lower end face of the opening in the middle of the membrane separation cylinder 3. A positioning ring 8 is nested in the cavity at the top edge of the receiving plate 7. The positioning ring 8 is fixed on the lower end face of the membrane separation cylinder 3. An electromagnet 9 is fixed on the outside of the positioning ring 8. The outer side of the scraper 61 is set as an inclined structure, the scraper 61 is parallel to the inclined surface of the membrane separation cylinder 3, and the scraper 61 is not in contact with the membrane separation cylinder 3 at its initial position; the positioning ring 8 slides in contact with the cavity at the top of the receiving plate 7, and the inner wall of the cavity at the top of the receiving plate 7 is magnetically attracted to the electromagnet 9 using magnetic material. The telescopic assembly includes a first guide head 101 and a first guide groove 102. The first guide head 101 is fixed on the outside of the central shaft 6. The outer end of the first guide head 101 is slidably disposed in the first guide groove 102. The first guide groove 102 is opened on the hollow side wall in the middle of the receiving plate 7. The first guide groove 102 is distributed in a spiral structure. Motor 2 drives the limiting telescopic rod 4 to rotate reciprocally, which in turn drives the mounting plate 5 to rotate. The mounting plate 5 rotates within the push plate 112 via bearings, preventing interference. The mounting plate 5 drives the central shaft 6 to rotate. At this time, the electromagnet 9 attracts and fixes the receiving plate 7. The central shaft 6 rotates within the receiving plate 7. Through the first guide head 101 and the first guide groove 102 of the spiral structure, the central shaft 6 can move up and down synchronously during rotation, thereby driving the scraper 61 to rotate and move up and down, breaking up the agglomerates in the wastewater.

[0021] In one embodiment of the present invention, a push assembly is disposed between the inner top of the body 1 and the mounting plate 5 for adjusting the position of the mounting plate 5; the push assembly includes an electric push rod 111 and a push plate 112, the electric push rod 111 is fixed inside the top of the body 1, the bottom output end of the electric push rod 111 is connected to the push plate 112, and the push plate 112 is connected to the outer side of the mounting plate 5 through a bearing. The material discharge assembly is installed inside the receiving plate 7 for sealing and discharging the material. The material discharge assembly includes a material discharge plate 121, which is embedded and rotatably installed inside the cavity of the receiving plate 7. The material discharge plate 121 and the receiving plate 7 are respectively provided with a first material discharge hole 122 and a second material discharge hole 125. A second guide groove 123 is provided on the outer side of the material discharge plate 121. A second guide head 124 is provided in the second guide groove 123 and is fixed on the inner wall of the positioning ring 8. The first discharge hole 122 and the second discharge hole 125 are distributed at equal angles on the discharge plate 121 and the receiving plate 7, respectively. Both the first discharge hole 122 and the second discharge hole 125 are set as fan-shaped structures, and the initial positions of the first discharge hole 122 and the second discharge hole 125 are staggered. The second guide head 124 slides in contact with the second guide groove 123, and the second guide groove 123 is designed as a spiral structure. After filtration, the cleaning water is introduced into the interior through an external pipeline, and the mounting plate 5 is moved down by the electric push rod 111 and push plate 112. At the same time, the electromagnet 9 is de-energized and no longer fixes the receiving plate 7. At this time, the receiving plate 7 moves down under gravity, making room at the bottom of the membrane separation cylinder 3. Simultaneously, the scraper 61 moves to the top surface of the membrane separation cylinder 3, and the receiving plate 7 moves up and down on the positioning ring 8. The second guide groove 123 and the second guide head 124 of the spiral structure drive the leakage plate 121 to rotate, so that the first leakage hole 122 on the leakage plate 121 and the second leakage hole 125 on the receiving plate 7 coincide, achieving the effect of leakage. The motor 2 and the limiting telescopic rod 4 drive the central shaft 6 to rotate again. At this time, the receiving plate 7 is no longer restricted, and the central shaft 6 only drives the scraper 61 to rotate, scraping off the impurities on the membrane separation cylinder 3. The impurities are discharged through the gap between the bottom of the membrane separation cylinder 3 and the receiving plate 7, as well as through the first leakage hole 122 and the second leakage hole 125, thus cleaning the impurities.

[0022] As one embodiment of the present invention, the method includes the following steps: S1: The high-salt, high-concentration organic wastewater to be treated is injected into the equipment through the feed pipe at the top of the machine body 1, and the wastewater is separated and filtered through the membrane separation cylinder 3; S2: Start motor 2. Motor 2 drives the mounting plate 5 and central shaft 6 to rotate through the limit telescopic rod 4. The first guide head 101 slides along the spiral first guide groove 102 on the hollow side wall of the middle part of the receiving plate 7, driving the central shaft 6 to move up and down synchronously. The scraper 61 rotates with the central shaft 6 and moves up and down to break up the aggregated impurities in the wastewater. S3: After filtration, cleaning water is injected into the machine body 1 through the external pipeline, the electromagnet 9 is turned off, the adsorption and fixation of the receiving plate 7 is released, and the electric push rod 111 drives the mounting plate 5 and the central shaft 6 to move down through the push plate 112, so that the scraper 61 is in contact with the top surface of the membrane separation cylinder 3. S4: The receiving plate 7 moves up and down on the positioning ring 8, causing the material leakage plate 121 to rotate, so that the first material leakage hole 122 and the second material leakage hole 125 overlap. The motor 2 drives the central shaft 6 to rotate again, scraping off the impurities on the membrane separation cylinder 3. At the same time, the impurities are discharged through the first material leakage hole 122 and the second material leakage hole 125 for impurity cleaning.

[0023] Working principle: First, wastewater is introduced into the machine body 1 through the feed pipe. The wastewater is filtered and guided through the conical membrane separator 3. The filtered liquid is discharged through the bottom pipe of the machine body 1. During this process, the motor 2 drives the limit telescopic rod 4 to rotate back and forth. The limit telescopic rod 4 drives the mounting plate 5 to rotate. The mounting plate 5 rotates in the inner end of the push plate 112 through the bearing, without causing interference. The mounting plate 5 drives the central shaft 6 to rotate. At this time, the electromagnet 9 attracts and fixes the receiving plate 7. The central shaft 6 rotates in the receiving plate 7. Through the first guide head 101 and the first guide groove 102 of the spiral structure, the central shaft 6 can move up and down synchronously when rotating, thereby driving the scraper 61 to rotate and move up and down, breaking up the agglomerates in the wastewater. After filtration, the cleaning water is introduced into the interior through an external pipeline, and the mounting plate 5 is moved down by the electric push rod 111 and push plate 112. At the same time, the electromagnet 9 is de-energized and no longer fixes the receiving plate 7. At this time, the receiving plate 7 moves down under gravity, making room at the bottom of the membrane separation cylinder 3. Simultaneously, the scraper 61 moves to the receiving plate 7 and moves up and down on the positioning ring 8. On the top surface of the membrane separation cylinder 3, the second guide groove 123 and the second guide head 124 of the spiral structure drive the leakage plate 121 to rotate, so that the first leakage hole 122 on the leakage plate 121 and the second leakage hole 125 on the receiving plate 7 coincide, achieving the effect of leakage. The motor 2 and the limiting telescopic rod 4 drive the central shaft 6 to rotate again. At this time, the receiving plate 7 is no longer restricted, and the central shaft 6 only drives the scraper 61 to rotate, scraping off the impurities on the membrane separation cylinder 3. The impurities are discharged through the gap between the bottom of the membrane separation cylinder 3 and the receiving plate 7, as well as through the first leakage hole 122 and the second leakage hole 125, thus cleaning the impurities.
