Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater purification and treatment device and process based on environmentally friendly production. Background Technology

[0002] With the increasing emphasis on environmentally friendly production, the amount of wastewater discharged from industrial production and urban life continues to increase. The large amount of suspended particulate matter and solid sediment contained in the wastewater will seriously pollute water resources and disrupt the ecological balance if discharged directly. Therefore, wastewater purification and treatment has become one of the core tasks in the field of environmental protection.

[0003] Currently, common wastewater purification processes include physical, chemical, and biological methods. Among them, physical methods are widely used in the pretreatment stage due to their simple operation and low cost. In particular, mechanical bar screens are commonly used as the core component of the pretreatment stage in the primary filtration stage. Through the gaps in the screen holes, they can intercept and filter larger suspended particles (such as silt, fibers, and debris) in the wastewater.

[0004] Because suspended particulate matter in wastewater easily adsorbs onto the surface of the grid during filtration, especially highly viscous impurities, which gradually adhere to the inner wall of the grid holes and the surface of the grid. As the usage time increases, the grid holes will gradually become blocked. Furthermore, the wastewater filtered by the grid needs to be transferred to subsequent tanks (such as settling tanks or reaction tanks) for further treatment. Since the attached substances in the wastewater continue to be in contact with the grid, they corrode the grid material over a long period of time, shortening its service life. To alleviate this corrosion problem, additional water resources are required to perform a secondary cleaning of the grid to remove the attached corrosive substances, which is quite wasteful of water resources. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a wastewater purification treatment device and process based on environmentally friendly production.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention discloses a wastewater purification and treatment device and process based on environmentally friendly production. Example 1

[0023] Reference Figure 1-7This is the first embodiment of the present invention, providing a wastewater purification and treatment device based on environmentally friendly production. This device includes a purification chamber 1 and a drain tank 2. The drain tank 2 is fixedly installed at the bottom of the purification chamber 1. A purification chamber 11 is provided in the purification chamber 1 above the drain tank 2. A grid mechanism 3 for filtering impurities is provided in the purification chamber 11 above the drain tank 2. The purification chamber 1 also has a water collection mechanism 4 and a rinsing mechanism 5 for providing rinsing water to the grid mechanism 3. A sewage discharge chamber 111 communicating with the purification chamber 11 is symmetrically distributed on the inner wall of the purification chamber 1. Above the 1, a sewage inlet pipe 12 for introducing sewage is provided. The grid mechanism 3 includes an arc-shaped grid plate 31 movably connected in the purification chamber 11 and located between the sewage discharge chambers 111. The arc-shaped grid plate 31 has equidistantly arranged screen holes 311 distributed along its circumference. Both ends of the arc-shaped grid plate 31 are also provided with water-blocking skirts for shielding the sewage discharge chambers 111. A transmission arc frame 32 driven by a waterproof servo motor 35 is fixedly installed at the end of the arc-shaped grid plate 31. The transmission arc frame 32 is concentrically distributed with the arc-shaped grid plate 31. A bearing ring 321 is also provided at the end of the transmission arc frame 32 near the drain tank 2. The transmission arc frame 32 is rotatably connected to the purification chamber 1 through the bearing ring 321. The inner wall of the purification chamber 1 is integrally molded from a corrosion-resistant and environmentally friendly alloy material to ensure structural stability in long-term sewage environments. The drain tank 2 is fixedly connected to the purification chamber 1 by bolts, and the connection surface is fitted with a nitrile rubber sealing gasket to effectively prevent sewage leakage. The height and width of the purification chamber 11 are matched according to the designed treatment capacity to ensure a reasonable sewage flow path, and the arc-shaped grid plate 31 can rotate freely within it. The opening position of the drain chamber 111 is precisely matched with the rotation trajectory of the arc-shaped grid plate 31, facilitating the rapid discharge of impurities. The drain chamber 12 is inclined at one end of the purification chamber 11, and the sewage inlet pipe 12 adopts an inclined pipe opening design to reduce the impact on the grid when sewage is introduced. The impact force of the grid mechanism 3, the arc design of the arc-shaped grid plate 31, and the ability to be assembled with the external sewage pipe that has undergone coarse filtration through the flange, the arc design of the arc-shaped grid plate 31 can increase the filtration contact area, the water-blocking skirt is made of high elastic fluororubber material, and always fits against the inner wall of the purification chamber 11 during the rotation of the arc-shaped grid plate 31, avoiding a lot of sewage from the side of the sewage discharge chamber 111. The transmission arc frame 32 can drive the arc-shaped grid plate 31 to rotate in the purification box 1 with the bearing ring 321 as the center, and throw the impurities intercepted on it to the sewage discharge chamber 111, thereby reducing the probability of clogging the screen holes 311 after long-term use and reducing the cleaning frequency. The filtered sewage then enters the drain tank 2.

[0024] The transmission arc frame 32 has an arc-shaped surface at the end away from the bearing ring 321, and an arc-shaped groove 322 distributed along its contour is formed on the arc-shaped surface of the transmission arc frame 32. An arc-shaped rack 33 adapted to the arc-shaped groove 322 is also slidably connected to the arc-shaped surface of the transmission arc frame 32. Both ends of the arc-shaped surface of the transmission arc frame 32 are fixedly installed with groove stops 323 to limit the movement of the arc-shaped rack 33. The arc-shaped surface of the transmission arc frame 32 is polished and waterproof electroplated, which can effectively reduce the sliding friction with the arc-shaped rack 33. To reduce friction, the slide block 323 is fixed to the transmission arc frame 32 by an internal hexagon screw. A polyurethane buffer pad is attached to the end face of the arc rack 33 facing the arc rack 33 to reduce rigid collisions when the arc rack 33 moves to its limit position. The arc rack 33 transmits power by precisely meshing with the driven gear 34. Both surfaces are coated with anti-corrosion coating to enhance corrosion resistance in sewage environments. When the arc rack 33 is not in contact with the slide block 323, even if it meshes with the driven gear 34, the driven gear 34 will not rotate.

[0025] Above the arc-shaped rack 33, there is a driven gear 34 that meshes with the arc-shaped rack 33. A gear shaft 341, integrally formed with the driven gear 34, is fixedly mounted on the driven gear 34. The driven gears 34 are rotatably connected to the inner wall of the purification chamber 1 via corresponding gear shafts 341. Between the driven gears 34 and above the arc-shaped grid plate 31, there is a cleaning roller 342 for assisting in cleaning the arc-shaped grid plate 31. A waterproof servo motor 35 is fixedly mounted on the purification chamber 1, and its output shaft is driven by a power arm 351. The power arm 351 is also equipped with a connecting rod 352 that is hinged to the transmission arc frame 32. A seated bearing is fitted at the connection between the gear shaft 341 and the inner wall of the purification chamber 1. A skeleton oil seal is provided inside the bearing seat to prevent sewage from entering the bearing and affecting rotation. The cleaning roller 342... The axis of 42 is parallel to the generatrix of the arc-shaped grid plate 31. The height is set to ensure the fit with the surface of the arc-shaped grid plate 31. When the arc-shaped rack 33 abuts against the slide block 323, the arc-shaped rack 33 is driven to swing through the transmission arc frame 32, thereby driving the cleaning roller 342 on the meshing driven gear 34 to rotate, thus assisting the swing of the arc-shaped grid plate 31 and further assisting in cleaning the arc-shaped grid plate 31. Through the coordinated action of the connecting rod 352 and the power arm 351, the rotational power of the output shaft of the waterproof servo motor 35 can be converted into the swinging power of the transmission arc frame 32, thereby realizing the pendulum motion of the arc-shaped grid plate 31. The hinges between them are all connected by stainless steel pins. The two ends of the pins are equipped with cotter pins to prevent dislodgement. Waterproof grease is applied to the hinge gap to ensure rotational flexibility and isolate sewage corrosion.

[0026] Both ends of the cleaning roller 342 are fixedly connected to one end of the gear shaft 341 extending into the purification chamber 11. The cleaning roller 342 is also provided with rubber scrapers distributed along its length. The rubber scrapers on the cleaning roller 342 are arranged to avoid each other with the driven gear 34. The rubber scrapers are made of industrial-grade wear-resistant silicone rubber, which has both elasticity and scraping force. The end face of the scraper is ground flat and fits tightly with the surface of the arc-shaped grid plate 31. The avoidance design between the scraper and the driven gear 34 is achieved by accurately calculating the installation position. During the intermittent rotation of the scraper following the cleaning roller 342, it can form a reverse scraping force on the impurities attached to the screen holes 311 and the grid plate surface, thereby improving cleaning efficiency.

[0027] The interior of the drain tank 2 is connected to the outlet of the purification chamber 11. The drain tank 2 is funnel-shaped and is equipped with a drain pipe 21 connected to the purification chamber 11. The drain pipe 21 is equipped with a valve for controlling the on / off state. The funnel-shaped structure of the drain tank 2 can use gravity to quickly guide the filtered sewage, reducing residue in the tank. The bottom of the drain tank 2 is also equipped with a spare drain valve (with blind flange seal) to facilitate the periodic cleaning of small amounts of impurities deposited in the tank and ensure smooth drainage.

[0028] The water collection mechanism 4 includes settling tanks 41 symmetrically distributed on both sides of the purification chamber 1. Each settling tank 41 has a clean water chamber 411 for containing clarified wastewater. The settling tank 41 also has a drain port 412 connected to the clean water chamber 411. The drain port 412 and the drain chamber 111 are correspondingly arranged. The settling tank 41 adopts a cylindrical structure and can introduce impurities and wastewater from the drain chamber 111 through the drain port 412. The water source is obtained through settling. The volume of the clean water chamber 411 is designed according to the water consumption of the flushing mechanism 5 to ensure that no additional water is needed for a single flush. The diameter of the drain port 412 is larger than that of the drain chamber 111. The two are connected by a corrugated hose. The hose is tightened with clamps at both ends to absorb installation errors and displacement when the arc-shaped grid plate 31 rotates. The hose is equipped with a corresponding flow valve and a pressure safety valve to facilitate observation of its internal status.

[0029] A sludge hopper 42 is fixedly installed on the inner wall of the settling tank 41, forming a sludge chamber 413 between the sludge hopper 42 and the clean water chamber 411. A sludge discharge pipe 4131 connected to the sludge chamber 413 is fixedly installed at the bottom of the settling tank 41, and a valve for controlling the on / off state is provided on the sludge discharge pipe 4131. An overflow pipe 43 connected to the flushing mechanism 5 is also provided on the settling tank 41. The sludge hopper 42 adopts a conical structure, which can guide all the sludge from the sewage discharge chamber 111 into the sludge chamber 413 and discharge it through the sludge discharge pipe 4131 at regular intervals. The discharge method can be selected as negative pressure or pump suction. The outlet of the sludge discharge pipe 4131 can be connected to a sludge collection device, which meets the requirements of environmental protection. The diameter of the overflow pipe 43 is designed according to the overflow flow of the clean water chamber 411, and the inclination angle is designed to ensure that the clarified sewage flows to the water storage tank 51 by gravity without the need for additional power and additional cleaning water, which is more in line with the requirements of energy conservation and environmental protection.

[0030] The rinsing mechanism 5 includes a water storage tank 51 fixedly installed on the purification chamber 1. An infusion pipe 511 is fixedly installed at the top of the water storage tank 51. A shower head frame 512 is fixedly installed at one end of the infusion pipe 511 extending into the purification chamber 1, and the shower head frame 512 is located above the arc-shaped grid plate 31. A pump 52 for drawing water from the water storage tank 51 is also provided on the infusion pipe 511. The water storage tank 51 is connected to the clean water chamber 411 via an overflow pipe 43, and the end of the overflow pipe 43 extending outside the settling tank 41 is inclined towards the water storage tank 51. The water storage tank 51 has a cylindrical structure that can centrally collect and store the cleaning water transported by the overflow pipe 43. The shower head frame 512 has an arc-shaped structure and evenly distributed shower heads on the frame, which has both rinsing and atomizing cleaning modes, which can improve the rinsing effect and save water resources. The top of the water storage tank 51 is also equipped with a water inlet, which can replenish the clean water source in special circumstances to ensure the continuous operation of the device. The connection between the shower head frame 512 and the purification box 1 is a detachable structure, which can be cleaned and replaced through the maintenance manhole on the purification box 1.

[0031] In the process of purifying wastewater that has already been filtered to remove large impurities, the wastewater to be treated is first introduced into the purification chamber 11 of the purification tank 1 through the inclined sewage inlet pipe 12. When the wastewater flows through the arc-shaped grid plate 31 located in the middle of the purification chamber 11, the sieve holes 311 on the grid plate intercept and filter the suspended particulate matter and solid impurities in the wastewater. During the filtration process, the water-blocking skirts at both ends of the arc-shaped grid plate 31 are always in contact with the inner wall of the purification chamber 11 to prevent a large amount of wastewater from leaking from the side of the sewage discharge chamber 111. This ensures that most of the wastewater permeates through the sieve holes 311 to the lower drainage tank 2. The pre-purified wastewater is discharged through the drainage pipe 21 under the gravity guidance of the funnel-shaped drainage tank 2. The waterproof servo motor 35 is started, and the rotational power of its output shaft is transmitted to the transmission arc frame 32 through the power arm 351 and the connecting rod 352. Since the transmission arc frame 32 is rotatably connected to the purification box 1 through the bearing ring 321 and is concentrically distributed with the arc-shaped grid plate 31, the rotational power is finally converted into the pendulum swing of the arc-shaped grid plate 31. During the swing of the arc-shaped grid plate 31, centrifugal force is generated, which throws most of the impurities intercepted on the surface to the symmetrically distributed sewage chambers 111 on both sides, realizing the initial removal of impurities, thereby reducing the cleaning frequency. When the transmission arc frame 32 swings to its limit position, the arc rack 33 comes into contact with the slide block 323. At this time, the continuous swing of the transmission arc frame 32 drives the arc rack 33 to slide along the arc slide 322. Since the arc rack 33 is precisely meshed with the driven gear 34, it drives the driven gear 34 and the coaxially fixed cleaning roller 342 to rotate. The industrial-grade wear-resistant silicone rubber scraper on the cleaning roller 342 is in close contact with the surface of the arc grid plate 31. During the rotation, it forms a reverse scraping force on the sticky impurities and residual particles on the screen hole 311, further reducing the probability of the screen hole 311 being blocked. When the transmission arc frame 32 swings in the opposite direction, the arc rack 33 is disengaged from the limit position, and the driven gear 34 stops rotating, completing one intermittent cleaning cycle, which meets its energy-saving and environmental protection requirements. Impurities and a small amount of sewage discharged from the sewage discharge chamber 111 are introduced into the settling tanks 41 on both sides through the corrugated hose and the sewage outlet 412. The sewage is separated by gravity settling in the settling tank 41. The sludge is guided to the bottom sludge chamber 413 by the sludge hopper 42 and periodically discharged to the sludge collection device through the sludge discharge pipe 4131 to avoid secondary pollution. The clarified sewage after settling is stored in the clean water chamber 411. When the water level reaches the preset height, it flows by gravity to the water storage tank 51 through the inclined overflow pipe 43, realizing the recycling of the cleaning water source without the need for additional consumption of clean water resources. The circulating water in the water storage tank 51 can be drawn out by the liquid pump 52 and transported to the arc-shaped shower head frame 512 through the liquid delivery pipe 511. The nozzle can switch between rinsing or atomizing modes to assist in cleaning the arc-shaped grid plate 31.

[0032] A wastewater purification and treatment process based on environmentally friendly production includes the following steps: Step 1: When the device is needed, the wastewater to be treated is first introduced into the purification chamber 11 through the inclined sewage inlet pipe 12. After being filtered by the arc-shaped grid plate 31, the preliminarily purified wastewater is discharged from the drain pipe 21 of the drain tank 2. Step 2: Then, by starting the waterproof servo motor 35, the transmission arc frame 32 is driven through the power arm 351 and the connecting rod 352, which drives the arc grid plate 31 to swing in a pendulum manner, using centrifugal force to throw the impurities toward the sewage discharge chamber 111. Step 3: When the transmission arc frame 32 is swung to its limit position, the arc rack 33 drives the driven gear 34 to rotate the cleaning roller 342, and scrapes off the residual impurities in the sieve hole 311 through the scraper to complete the intermittent cleaning. Step 4: The impurities and a small amount of sewage discharged from the sewage discharge chamber 111 are introduced into the settling tank 41 through the sewage discharge port 412. After settling, the sludge is discharged from the sludge discharge pipe 4131, and the clarified sewage is recovered to the water storage tank 51 through the overflow pipe 43. Step 5: When auxiliary cleaning is required, the circulating water in the water storage tank 51 is transported to the shower head frame 512 by the liquid pump 52 to clean the arc-shaped grid plate 31.
