Description

Technical Field

[0001] This invention belongs to the field of high-salinity wastewater treatment technology, specifically a high-salinity wastewater treatment process and equipment. Background Technology

[0002] According to the patent document with authorization announcement number "CN116272070B" and invention title "A High-Salinity Wastewater Treatment Process", the description states that: the filter plate is inclined inside the main body. Wastewater entering the main body through the inlet pipe is filtered by the filter plate, and simultaneously flows downwards along the inclined surface of the filter plate. This carries the impurities filtered out on the surface of the filter plate towards the lower part of the inclined direction, causing the impurities to concentrate near the outlet on the filter plate. Then, workers periodically open the blockage at the outlet to clean the impurities accumulated near the outlet, preventing impurity buildup and clogging of the filter holes. Simultaneously, because the impurities filtered out on the filter plate are concentrated near the outlet due to the inclined angle of the filter plate and the water flow, relatively few impurities remain on other parts of the filter plate surface, which can reduce the possibility of filter plate clogging to a certain extent and extend the maintenance cycle of the filtration equipment. However, the following drawbacks still exist:

[0003] During filtration, impurities adhere to the surface of the filter plate or in the filter holes, and may not easily accumulate at lower levels, making it difficult for impurities to self-clean. The chance of filter plate clogging is still relatively high, resulting in low filtration efficiency for high-salt wastewater. Furthermore, the filtration effect of high-salt wastewater passing through the filter plate once is not good. Summary of the Invention

The fan blade is connected to the space inside the plate groove located below the pressure plate through the air inlet groove.

[0012] Preferably, the circulating filtration assembly includes a lifting chamber located inside the treatment chamber, on the side of the wastewater storage chamber away from the impurity storage chamber. A return pipe is installed at the top of the lifting chamber near the treatment chamber, above the wastewater storage chamber. A lifting piston plate is movably installed inside the lifting chamber, with a pull rod installed at the top of the lifting piston plate extending to the top of the treatment chamber. A toothed plate is installed at the top of the pull rod, located on the front of the treatment chamber. A half gear is meshed with one side of the toothed plate, rotatably mounted on the front of the treatment chamber. A second driven sprocket is coaxially mounted on the front of the half gear.

A second chain is installed on the outer side of the second driving sprocket and the second driven sprocket. A drainage slope is provided at the top of the lifting piston plate, and a tank switch unit is provided on one side of the lifting piston plate.

[0013] Preferably, the tank switching unit includes a connecting water tank located at the bottom end of the lifting chamber near the processing chamber. A receiving groove is provided on the inner bottom wall of the connecting water tank. A baffle is movably installed inside the receiving groove. A sealing plate is installed at the top of the baffle. The top wall of the sealing plate, the bottommost end of the top wall of the lifting piston plate, and the inner bottom wall of the processing chamber are flush. Bottom springs are symmetrically installed at the bottom of the baffle. A pressure groove is provided at the bottom end of the lifting piston plate near the sealing plate.

[0014] Preferably, an inlet pipe is installed at the top of the reflux pipe, and a drain pipe is installed at the bottom of the treatment tank. The drain pipe is located below the wastewater storage chamber. Valves are installed on both the inlet pipe and the drain pipe, and bases are symmetrically installed at the bottom of the treatment tank.

[0015] A preferred method for treating high-salinity wastewater is characterized by the following treatment steps:

[0016] S1. Inlet water filtration: Turn on the drive motor to drive the filter belt to move, and at the same time, pass the wastewater from the return pipe into the wastewater storage chamber, and filter the wastewater using the filter holes on the filter belt.

[0017] S2, Impurity Scraping: When the bottom surface of the filter belt passes over the scraper head, the scraper head scrapes the impurities on the bottom surface of the filter belt into the impurity storage chamber;

[0018] S3. Impurity removal: The rotation of the active roller drives the cam to rotate, which in turn drives the beater plate to move longitudinally back and forth, beating the inner wall of the filter belt and knocking off the impurities attached to the surface of the filter belt and inside the filter holes.

[0019] S4. Circulating filtration: The rotation of the active roller drives the half gear to rotate. When the half gear meshes with the toothed plate, it drives the lifting piston plate to move upward, and discharges the wastewater above the lifting piston plate back down from the return pipe body for re-filtration. After the half gear disengages from the toothed plate, the lifting piston plate moves back to re-store water.

[0020] S5. Drainage and Impurity Removal: After filtration, open the valve on the drain pipe to drain the filtered wastewater, and then open the cleaning door to open the impurity storage chamber for impurity cleaning.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1) During operation, the inside of the treatment chamber is equipped with an inclined filter belt. When wastewater enters the wastewater storage chamber, it is filtered through the filter holes, which are evenly distributed on the filter belt. The filter belt moves continuously, and while continuing to filter, it passes over the scraper head. The scraper head removes the impurities attached to the filter belt, ensuring the filtration effect and reducing clogging.

[0023] 2) During operation, the active roller rotates to drive the filter belt to move while simultaneously driving the cam to rotate, intermittently generating pressure on the pressure plate, which in turn drives the beater plate to move longitudinally back and forth, continuously beating the inner bottom wall of the filter belt, thereby knocking off impurities attached to the bottom surface of the filter belt and inside the filter holes into the impurity storage cavity, further facilitating impurity removal.

[0024] 3) During operation, as the cam rotates continuously, it draws outside air into the space below the pressure plate through the air intake pipe, increasing the pressure between the top of the scraper head and the bottom surface of the filter belt. This further improves the scraping effect of the scraper head on the bottom surface of the filter belt, facilitating subsequent impurity removal.

[0025] 4) During operation, the wastewater can enter the space above the lifting piston plate inside the lifting chamber through the connecting water tank. The active roller rotates and drives the half gear to rotate. When the half gear meshes with the toothed plate, the lifting piston plate moves upward and pushes the wastewater back from the return pipe. After the half gear disengages from the toothed plate, the lifting piston plate moves back to draw water again, so that the wastewater can be circulated for filtration, improving the filtration effect of high-salt wastewater.

[0026] 5) During operation, the side plate of the sealing plate is located in the pressure groove on the lifting piston plate. When the lifting piston plate moves upward, the baffle moves upward under the elastic force of the bottom spring, closing the water tank and preventing wastewater from entering the space below the lifting piston plate, which would affect subsequent water lifting. When the lifting piston plate moves downward, it presses the baffle down again, making it easier for wastewater to enter the space above the lifting piston plate, thus facilitating wastewater circulation and filtration.

An active roller 605 is provided on the top of the side of the impurity storage chamber away from the wastewater storage chamber, and a driven roller 604 is provided on the side of the wastewater storage chamber away from the impurity storage chamber. A filter belt 602 is installed on the outer side of the driven roller 604 and the active roller 605. The end of the filter belt 602 near the driven roller 604 is inclined downward. Filter holes 603 are evenly opened on the filter belt 602. An impurity removal assembly 7 is installed inside the partition 601. A circulating filter assembly 8 is installed inside the processing box 1. The shaft of the active roller 605 near the back of the processing box 1 is fixedly connected to the output shaft of the drive motor 606. The drive motor 606 is fixedly installed on the back of the processing box 1. A cleaning trough 607 is opened on the side of the impurity storage chamber away from the wastewater storage chamber. The cleaning trough 607 is located below the active roller 605. A cleaning door 608 is rotatably installed inside the cleaning trough 607.

[0041] The impurity removal assembly 7 includes a plate groove 701 formed inside the partition 601. A pressure plate 702 is slidably installed inside the plate groove 701. The outer wall of the pressure plate 702 is in close contact with the inner wall of the plate groove 701. A scraper 703 is installed at the top of the pressure plate 702. The top wall of the scraper 703 is in close contact with the middle of the inclined bottom wall of the filter belt 602. A clamping spring 704 is symmetrically installed at the bottom end of the pressure plate 702. The bottom end of the clamping spring 704 is fixedly connected to the inner bottom wall of the plate groove 701. The filter belt 6... The inner side of 02 is provided with a beater and impurity removal unit 705, and the inside of the treatment chamber 5 is provided with an inclined filter belt 602. When wastewater enters the wastewater storage chamber, it is filtered through the filter holes 603. The filter holes 603 are evenly distributed on the filter belt 602. The filter belt 602 moves continuously and passes over the scraper head 703 while continuing to filter. The scraper head 703 scrapes off the impurities attached to the filter belt 602 to ensure the filtration effect and reduce clogging.

[0042] The tapping impurity removal unit 705 includes a cam 7051 disposed inside the filter belt 602 near one end of the drive roller 605. The cam 7051 is rotatably connected to the processing box 1. A first driven sprocket 7052 is mounted on the end of the cam 7051 near the front of the processing box 1. A first drive sprocket 7053 is mounted on the end of the drive roller 605 near the front of the processing box 1. A first chain 7054 is mounted on the outer side of the first driven sprocket 7052 and the first drive sprocket 7053. A vibrating element is disposed below the cam 7051. An auxiliary pressing unit 706 is installed between the cam 7051 and the plate groove 701. The vibrating element includes a fixing plate 7055 disposed below the cam 7051. The fixing plate 7055 is connected to the processing box. 1. Fixed installation: A pressing plate 7057 and a tapping plate 7056 are respectively provided on the upper and lower sides of the fixed plate 7055. A connecting rod 7058 is symmetrically installed between the pressing plate 7057 and the tapping plate 7056. A return spring 7059 is symmetrically installed between the pressing plate 7057 and the fixed plate 7055. When the drive roller 605 rotates, it drives the filter belt 602 to move and drives the cam 7051 to rotate, intermittently generating pressure on the pressing plate 7057, which in turn drives the tapping plate 7056 to move longitudinally back and forth, continuously producing a tapping effect on the inner bottom wall of the filter belt 602, thereby knocking off the impurities attached to the bottom surface of the filter belt 602 and inside the filter holes 603 into the impurity storage cavity, further facilitating impurity removal.

[0043] The auxiliary pressing unit 706 includes a fan blade 7062 opened inside the cam 7051. Both ends of the fan blade 7062 pass through both ends of the cam 7051. Air inlet pipes 7063 are evenly installed on the inner wall of the fan blade 7062. An air inlet groove 7061 is installed on the back of the processing box 1. The fan blade 7062 is connected to the space inside the plate groove 701 located below the pressure plate 702 through the air inlet groove 7061. When the cam 7051 rotates continuously, it drives outside air into the space inside the plate groove 701 located below the pressure plate 702 through the air inlet pipe 7063, which increases the pressing effect between the top of the scraper head 703 and the bottom surface of the filter belt 602, thereby further improving the scraping effect of the scraper head 703 on the bottom surface of the filter belt 602 and facilitating subsequent impurity removal.

[0044] The circulating filter assembly 8 includes a lifting chamber 801 located inside the treatment chamber 1. The lifting chamber 801 is situated on the side of the wastewater storage chamber away from the impurity storage chamber. A return pipe 804 is installed at the top of the lifting chamber 801 near the treatment chamber 5, and the return pipe 804 is positioned above the wastewater storage chamber. A lifting piston plate 805 is movably installed inside the lifting chamber 801. A pull rod 806 is installed at the top of the lifting piston plate 805, extending through to the top of the treatment chamber 1. A toothed plate 807 is installed at the top of the pull rod 806, and the toothed plate 807 is located on the front of the treatment chamber 1. A half gear 808 is meshed with one side of the toothed plate 807. The half gear 808 is rotatably mounted on the front of the treatment box 1. A second driven sprocket 809 is coaxially mounted on the front of the half gear 808. A second driving sprocket 810 is mounted on one end of the driving roller 605 near the front of the treatment box 1. A second chain 811 is mounted on the outside of the second driving sprocket 810 and the second driven sprocket 809. Wastewater can enter the space above the lifting piston plate 805 from the connecting water tank 802 into the lifting chamber 801. The rotation of the driving roller 605 drives the half gear 808 to rotate simultaneously.

[0045] When the half gear 808 meshes with the toothed plate 807, the lifting piston plate 805 moves upward to push the wastewater back from the return pipe 804. After the half gear 808 disengages from the toothed plate 807, the lifting piston plate 805 moves back to re-collect water, allowing the wastewater to circulate and be filtered, improving the filtration effect on high-salt wastewater. A drainage slope is provided at the top of the lifting piston plate 805, and a tank switch unit 812 is provided on one side of the lifting piston plate 805. The tank switch unit 812 includes a connecting water tank 802 opened at the bottom end of the lifting cavity 801 near the processing cavity 5. A receiving groove 8121 is opened on the inner bottom wall of the connecting water tank 802. A baffle 8122 is installed inside the cavity 1. The top of the baffle 8122 is installed on the sealing plate 8123. The top wall of the sealing plate 8123, the bottom of the top wall of the lifting piston plate 805, and the bottom wall of the processing cavity 5 are flush. Bottom springs 8124 are symmetrically installed at the bottom of the baffle 8122. A pressure groove 8125 is opened at the bottom of the end of the lifting piston plate 805 near the sealing plate 8123. A side plate 8126 is installed on the side of the sealing plate 8123 near the lifting piston plate 805. The side plate 8126 is located inside the pressure groove 8125. The side plate 8126 on one side of the sealing plate 8123 is located in the pressure groove 8125 on the lifting piston plate 805.

[0046] When the lifting piston plate 805 moves upward, the baffle 8122 moves upward under the elastic force of the bottom spring 8124, closing the water tank 802 and preventing wastewater from entering the space below the lifting piston plate 805, which would affect subsequent water lifting. When the lifting piston plate 805 moves downward, it presses the baffle 8122 down again, making it easier for wastewater to enter the space above the lifting piston plate 805 for wastewater circulation and filtration. The top of the return pipe 804 is equipped with an inlet pipe 3, and the bottom of the treatment tank 1 is equipped with a drain pipe 4, which is located below the wastewater storage chamber. Valves are installed on both the inlet pipe 3 and the drain pipe 4. The bottom of the treatment tank 1 is symmetrically equipped with a base 2.

[0047] Working principle:

[0048] During operation, the drive motor 606 is turned on first, and the active roller 605 is started to rotate clockwise, thereby driving the filter belt 602 to move. The top wall of the filter belt 602 moves upward. Then, the valve on the inlet pipe 3 is opened to let the high-salt wastewater flow from the return pipe 804 into the wastewater storage chamber. The high-salt wastewater is continuously filtered through the filter holes 603 on the filter belt 602, so that the impurities in the high-salt wastewater are at the top of the filter belt 602. The filtered high-salt wastewater is stored in the wastewater storage chamber.

[0049] As the filter belt 602 moves, the top of the scraper head 703 is pressed against the middle of the bottom wall of the filter belt 602 by the elastic force of the compression spring 704, thereby scraping the impurities attached to the surface of the filter belt 602 into the impurity storage cavity, thus avoiding the impurities being carried back into the high-salt wastewater.

[0050] During the rotation of the drive roller 605, the first driven sprocket 7052, the first drive sprocket 7053, and the first chain 7054 drive the cam 7051 to rotate. As the cam 7051 rotates, it applies intermittent pressure to the top wall of the pressure plate 7057. Under pressure, the pressure pushes the beater plate 7056 downwards. After the pressure disappears, the beater plate 7056 moves upwards, causing it to continuously beat the inner bottom wall of the filter belt 602, dislodging the particles adhering to the filter holes 603 and the filter belt 6057. 02 Impurities on the bottom wall are knocked into the impurity storage cavity, which further facilitates the removal of filtered impurities and facilitates subsequent filtration. During the rotation of the cam 7051, the air intake pipe 7063 drives the outside air into the air inside the plate groove 701 located below the pressure plate 702 through the fan blade 7062 and the air intake groove 7061, thereby generating pressure on the bottom wall of the pressure plate 702, so that the top of the scraper 703 is pressed tightly against the lower surface of the filter belt 602, improving the scraping effect of impurities on the filter belt 602.

[0051] Simultaneously, some of the wastewater entering the wastewater storage chamber enters the lifting chamber 801 through the connecting water tank 802. Due to the distance between the communicating vessels, the liquid level in the wastewater storage chamber is flush with the liquid level inside the lifting chamber 801. When the drive roller 605 rotates, it drives the half-gear 808 to rotate clockwise via the second drive sprocket 810, the second driven sprocket 809, and the second chain 811. When the half-gear 808 is engaged with the toothed plate 807, it drives the lifting piston plate 805 to move upwards, thereby lifting the wastewater above the lifting piston plate 805 and pressing it out through the return pipe 804, thus raising the wastewater level. The saline wastewater flows back from the return pipe 804 to the wastewater storage chamber, and the impurities in the high-salt wastewater are circulated and filtered through the filter holes 603 on the filter belt 602 to improve the filtration effect. This prevents some impurities from being squeezed into the wastewater storage chamber through the filter holes 603 on the elastic filter belt 602 under pressure and thus not being easily filtered. When the half gear 808 disengages from the toothed plate 807, the lifting piston plate 805 moves downward back to its original position under the action of gravity. Then, after the half gear 808 re-engages with the toothed plate 807, it drives the lifting piston plate 805 to move upward again.

[0052] As the lifting piston plate 805 moves upward, the baffle 8122 moves upward under the elastic force of the bottom spring 8124 until the top wall of the sealing plate 8123 is in close contact with the top wall of the connecting water tank 802, isolating the lifting chamber 801 from the treatment chamber 5, preventing the wastewater in the lifting chamber 801 from flowing back directly, and preventing the wastewater from entering the space below the lifting piston plate 805. When the lifting piston plate 805 moves downward, it exerts pressure on the side plate 8126, pushing the baffle 8122 downward, so that the wastewater can flow back to the top of the lifting piston plate 805.

[0053] After multiple cycles of filtration, open the valve on drain pipe 4 to discharge the filtered wastewater from the waste gas storage chamber, and then open cleaning door 608 to clean the impurity storage chamber.
