Abstract
Description
Technical Field
[0001] This invention belongs to the field of water treatment technology, and in particular relates to a micro-sand-assisted coagulation and sedimentation water treatment device and its usage method. Background Technology
[0002] Nowadays, a large amount of water is consumed in daily life and industrial production, resulting in a significant amount of wastewater. Therefore, in order to save water and protect the environment, wastewater is treated before being discharged to reduce pollution. During the wastewater treatment process, flocculants and other agents are added to accelerate the sedimentation of particulate matter in the wastewater, thereby improving the wastewater treatment efficiency. Additionally, a certain amount of micro-sand can be added to further enhance the flocculation efficiency.
[0003] In the process of adding micro-sand, traditional equipment often uses fixed pipelines or quantitative addition methods. When the influent flow rate and sewage concentration fluctuate, the addition amount cannot be matched in real time. This can easily lead to insufficient addition resulting in poor coagulation effect, or excessive addition resulting in material waste. Furthermore, micro-sand is prone to accumulating and bridging in the silo, making it difficult to fall evenly and mix with sewage sufficiently, thus failing to play its role as a carrier for coagulation. Summary of the Invention
[0004] The purpose of this invention is to solve the problem that traditional dispensing equipment cannot adaptively dispense water according to the water flow rate, and to propose a micro-sand-assisted coagulation sedimentation water treatment equipment and its usage method.

[0008] As a further description of the above technical solution: The seeding assembly further includes a connecting column, which is installed at both ends of the pontoon and slidably disposed in the inclined groove inside the sliding frame. The pontoon floats as the water level changes, so as to push the sliding frame through the connecting column, thereby driving the slide plate to move.

[0010] As a further description of the above technical solution: The mixing assembly also includes a motor, which is mounted on one side of the sedimentation chamber and the output shaft of the motor is fixedly connected to the mixing rod. The second pulley is installed at the other end of the mixing rod, and a belt is provided on the outer wall of the second pulley; A reciprocating lead screw is rotatably mounted in a through hole inside a fixed base. A first pulley is mounted on one end of the reciprocating lead screw, and the outer wall of the first pulley is connected to a belt. The first pulley and a second pulley are driven by a belt.
[0011] As a further description of the above technical solution: The mixing component further includes: a pusher frame, which is slidably disposed in a groove inside the sand feeding chamber, and one end of the pusher frame is provided with a through hole corresponding to the reciprocating lead screw, and a slider corresponding to the threaded groove on the outer wall of the reciprocating lead screw is provided in the through hole; A cover plate is installed at one end of the push frame, and one side of the cover plate is in contact with the outer wall of the sand feeding chamber.
[0012] As a further description of the above technical solution: It also includes: a shielding assembly, the shielding assembly including a connecting frame disposed inside the sludge removal chamber; An electric push rod is installed on a boss on one side of the top of the mud removal chamber, and the telescopic rod of the electric push rod passes through the boss and is fixedly connected to the connecting frame. A fixing plate is installed on the inner wall of the sludge removal chamber, and multiple fixing plates are evenly arranged.
[0013] As a further description of the above technical solution: The shielding assembly further includes: a swing plate, which is rotatably mounted on both sides of the fixed plate, and a lever plate is installed at both ends of the swing plate; A shielding frame is installed at the bottom of the connecting frame, and multiple shielding frames are evenly arranged, with each shielding frame located between the fixed plates. A fixing rod is installed at the bottom end of the connecting frame, and a fixing frame is installed at the bottom end of the fixing rod; Limiting rods are installed on one side of the fixed frame, and limiting rods are provided on both the upper and lower sides of the actuating plate.
[0014] This invention also discloses a micro-sand-assisted coagulation sedimentation water treatment device and its usage method, comprising the following steps: S1. During the sedimentation process of wastewater, as water flows into the sedimentation tank through the inlet pipe, it gradually passes through the various spaces separated by the internal partitions. When the water flows over the first partition and into the second space, fine sand can leak out through the opening at the bottom of the sand feeding bin to mix with the water. Furthermore, when the water flows over the top of the partition, it impacts the baffle. As the water flow increases, the impact on the baffle increases, causing the baffle to rotate. This rotation drives the gears to rotate, which in turn moves the slide plate through the connection between the gears and the rack. This changes the area of the slide plate covering the bottom opening of the sand feeding bin, resulting in more fine sand falling as the water flow increases. S2. Furthermore, as the water flow increases, the water level on one side of the baffle changes under the action of the baffle. Since the pontoon is located on the water surface, the pontoon moves to a certain extent as the water level changes. At the same time, when the pontoon moves, it can squeeze the sliding frame through the connecting column, causing the sliding frame to move and further pull the slide plate, thereby ensuring that the slide plate can move a sufficient distance. S3. During sand feeding, the water flow and the micro-sand fall into the receiving bin as they pass over the partition. The motor then drives the mixing rod to rotate, mixing the water flow and micro-sand to ensure better mixing and achieve the desired effect. Furthermore, the rotation of the mixing rod drives the second pulley to rotate, which in turn drives the first pulley to rotate via a belt. The first pulley then drives the reciprocating screw to rotate. Since the through hole at one end of the push frame has a slider corresponding to the spiral groove on the outer wall of the reciprocating screw, the rotation of the reciprocating screw drives the push frame to move. This push frame then moves the micro-sand inside the sand feeding bin to ensure that the micro-sand is evenly distributed inside the bin and falls evenly during feeding. S4. When wastewater enters the sludge removal chamber after flocculation, the flocculated material can be blocked by the baffle and swing plate to prevent it from being discharged with the water flow. The sludge settled at the bottom of the sludge removal chamber can be discharged. Furthermore, depending on the water flow and the amount of sediment, the connecting frame can be moved by the electric push rod, which in turn moves the fixed rod and the fixed frame. Since the upper and lower sides of the push plate are equipped with limit rods, when the connecting frame moves the baffle, the swing frame can be moved by the limit rods to change the angle of the swing frame. At the same time, the distance between the swing frame and the baffle can be adjusted, thus achieving a good blocking effect under different water flow and flocculation conditions, thereby preventing the flocculated material from being discharged with the water flow.
[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by incorporating a spreading component, the design enables the baffle to rotate under the impact of the water flow as the water flow increases during the flocculation and sedimentation process of wastewater. This rotation, in turn, causes the sliding plate to move, thereby increasing the opening area at the bottom of the sand feeding chamber and thus increasing the amount of micro-sand fed in. The opening area at the bottom of the sand feeding chamber is adjusted according to the water flow rate to ensure sufficient micro-sand is fed in and mixed with the wastewater, thereby ensuring the effectiveness of the micro-sand.
[0016] 2. In this invention, by incorporating a mixing component, the mixing rod further mixes the micro-sand with the water flow during the mixing of micro-sand and wastewater, ensuring that the micro-sand plays its corresponding role and that the particles inside the wastewater can be successfully flocculated. Simultaneously, the reciprocating screw is driven by the transmission between the first and second pulleys, which in turn drives the push frame to move, thereby agitating the micro-sand inside the sand feeding chamber to ensure that the micro-sand is evenly distributed within the sand feeding chamber.
[0017] 3. In this invention, by incorporating a shielding component, the design enables the shielding frame and the swing plate to block the flocculated material in the water flow after large particles have been flocculated inside the water flow. This prevents the flocculated material from being discharged when the water flow exits, thus ensuring the separation of the water flow and the flocculated material. Furthermore, the distance between the shielding frame and the swing frame can be adjusted according to the size of the water flow and the amount of flocculated material to ensure the separation effect between the flocculated material and the water flow.

[0027] 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.
[0028] Please see Figures 1-8 This invention provides a technical solution: a micro-sand-assisted coagulation sedimentation water treatment device and its usage method, comprising a sedimentation tank 2, an inlet pipe 1 installed on one side of the sedimentation tank 2, and multiple partitions 3 evenly arranged inside the sedimentation tank 2, with adjacent partitions 3 staggered; a sludge removal tank 5 connected to the other side of the sedimentation tank 2, and a guide plate 4 installed inside the sludge removal tank 5, with the guide plate 4 located on one side of the end partition 3; and further comprising: The spreading component 7 includes a mounting base 703 installed at the top of the sedimentation tank 2, a sand feeding bin 702 installed at the top of the mounting base 703, and an opening at the bottom of the sand feeding bin 702. The sand feeding bin 702 is located above the water inlet baffle 3 of the sedimentation tank 2, and a fixing base 701 is installed on one side of the sand feeding bin 702. The slide plate 704 is slidably installed in the groove on one side of the mounting base 703, and the slide plate 704 fits against the bottom opening of the sand feeding bin 702; A rack 705 is mounted on the bottom end of a slide plate 704 and is slidably disposed inside a mounting base 703. The spreading component 7 also includes a baffle 707, with both ends of the baffle 707 having a rotating shaft that is rotatably installed in a through hole on one side of the corresponding mounting base 703, and the baffle 707 being located on one side of the top of the partition 3 at the bottom of the sand feeding bin 702. Gear 706 is mounted on both ends of baffle 707 and is rotatably disposed in the groove inside the mounting base 703, and the top of gear 706 meshes with rack 705; The spreading component 7 also includes a sliding frame 708, which is mounted on one side of the slide plate 704 and has an inclined groove on its inner side; The pontoon 710 is slidably mounted on the outer wall of the sliding strip on one side of the sand feeding bin 702 via a sliding groove on one side; The seeding assembly 7 also includes a connecting column 709, which is installed at both ends of the float box 710 and is slidably disposed in the inclined groove inside the sliding frame 708. The float box 710 floats when the water level changes, so as to push the sliding frame 708 through the connecting column 709, thereby driving the slide plate 704 to move.
[0029] The specific implementation is as follows: During the process of sedimentation of sewage, as the water flows into the sedimentation tank 2 through the inlet pipe 1, it can gradually pass through the various spaces separated by the internal partition 3 of the sedimentation tank 2. When the water flows through the first partition 3 and enters the second space, the micro-sand can leak out through the opening at the bottom of the sand feeding tank 702 to mix with the water flow. Furthermore, when the water flows over the top of the baffle 3, the water flow will impact the baffle 707. As the water flow increases, the impact on the baffle 707 will increase, and under the influence of the impact, the baffle 707 will rotate. As the baffle 707 rotates, it can drive the gear 706 to rotate. In this way, through the connection between the gear 706 and the rack 705, the slide plate 704 will move, thereby changing the area of the slide plate 704 blocking the bottom opening of the sand feeding bin 702. As the water flow increases, more fine sand will fall. Furthermore, as the water flow increases, the water level on one side of the baffle 3 changes under the action of the baffle 707. Since the float 710 is located on the water surface, it moves to a certain extent as the water level changes. At the same time, when the float 710 moves, it can squeeze the sliding frame 708 through the connecting column 709, causing the sliding frame 708 to move and further pull the slide plate 704, thereby ensuring that the slide plate 704 can move a sufficient distance.
[0030] The mixing component 8 includes a receiving platform installed on one side of the bottom of the sand feeding bin 702 corresponding to the partition plate 3; The mixing rod 808 is set in the groove above the receiving platform, and both ends of the mixing rod 808 pass through the sedimentation tank 2 and are rotatably connected to the sedimentation tank 2. The mixing assembly 8 also includes a motor 809, which is installed on one side of the sedimentation chamber 2, and the output shaft of the motor 809 is fixedly connected to the mixing rod 808; The second pulley 806 is installed at the other end of the mixing rod 808, and the outer wall of the second pulley 806 is provided with a belt 805. A reciprocating screw 803 is rotatably installed in the through hole inside the fixed base 701. A first pulley 804 is installed at one end of the reciprocating screw 803, and the outer wall of the first pulley 804 is connected to the belt 805. The first pulley 804 and the second pulley 806 are driven by the belt 805. The mixing component 8 also includes: a pusher frame 801, which is slidably disposed in the groove inside the sand feeding bin 702, and one end of the pusher frame 801 is provided with a through hole corresponding to the reciprocating screw 803, and a slider corresponding to the threaded groove on the outer wall of the reciprocating screw 803 is provided in the through hole; A cover plate 802 is installed at one end of the pusher frame 801, and one side of the cover plate 802 is in contact with the outer wall of the sand feeding bin 702.
[0031] The specific implementation is as follows: When sand is added, the water flow falls into the receiving bin 807 when it passes over the partition 3 and the micro sand. Then, the mixing rod 808 is driven by the motor 809 to rotate, so as to mix the water flow and micro sand through the rotation of the mixing rod 808, so as to further ensure that the micro sand and water flow can be better mixed together and ensure that the micro sand can play the corresponding role. Furthermore, when the mixing rod 808 rotates, it can drive the second pulley 806 to rotate, and drive the first pulley 804 to rotate through the belt 805. The first pulley 804 drives the reciprocating screw 803 to rotate. Since the through hole at one end of the push frame 801 is provided with a slider corresponding to the spiral groove on the outer wall of the reciprocating screw 803, the push frame 801 can be moved when the reciprocating screw 803 rotates. In this way, the push frame 801 moves the micro-sand inside the sand feeding bin 702 to ensure that the micro-sand can be evenly distributed inside the sand feeding bin 702 and fall evenly when the sand is fed.
[0032] The shielding component 6 includes a connecting frame 602 disposed inside the sludge bin 5; Electric push rod 601 is installed on a boss on one side of the top of the mud removal chamber 5, and the telescopic rod of electric push rod 601 passes through the boss and is fixedly connected to the connecting frame 602. Fixing plate 608 is installed on the inner wall of the sludge removal chamber 5, and multiple fixing plates 608 are evenly arranged. The shielding assembly 6 also includes: a swing plate 607, which is rotatably mounted on both sides of the fixed plate 608, and a toggle plate 606 is installed at both ends of the swing plate 607; A shielding frame 609 is installed at the bottom of the connecting frame 602, and multiple shielding frames 609 are evenly arranged, and all shielding frames 609 are located between the fixing plates 608. A fixing rod 603 is installed at the bottom of the connecting frame 602, and a fixing frame 604 is installed at the bottom of the fixing rod 603; Limiting rod 605 is installed on one side of fixed frame 604, and limiting rod 605 is provided on both the upper and lower sides of toggle plate 606.
[0033] The specific implementation is as follows: When the sewage enters the sludge removal chamber 5 after flocculation, the flocculated material can be blocked by the shielding frame 609 and the swing plate 607 to prevent it from being discharged with the water flow. The sludge settled can be discharged by the sludge removal module at the bottom of the sludge removal chamber 5. Furthermore, depending on the size of the water flow and the amount of sediment, the connecting frame 602 can be moved by the electric push rod 601 to move the fixed rod 603 and the fixed frame 604. Since the upper and lower sides of the actuating plate 606 are equipped with limit rods 605, when the connecting frame 602 moves the shielding frame 609, the swing frame can be moved by the limit rods 605 to change the angle of the swing frame. At the same time, the distance between the swing frame and the shielding frame 609 can be adjusted, thereby achieving a good shielding effect under different water flow and flocculation conditions, thus preventing the flocculated material from being discharged with the water flow.
[0034] This invention also discloses a micro-sand-assisted coagulation sedimentation water treatment device and its usage method, comprising the following steps: S1. During the sedimentation process of wastewater, as water flows into sedimentation tank 2 through inlet pipe 1, it gradually passes through the spaces separated by partition 3 inside sedimentation tank 2. When the water flows over the first partition 3 and into the second space, fine sand can leak out through the opening at the bottom of sand feeding bin 702 to mix with the water flow. Furthermore, when the water flows over the top of partition 3, the water flow will impact baffle 707. As the water flow increases, the impact on baffle 707 increases, causing baffle 707 to rotate. As baffle 707 rotates, it can drive gear 706 to rotate. Through the connection between gear 706 and rack 705, it drives slide plate 704 to move, thereby changing the area of slide plate 704 blocking the bottom opening of sand feeding bin 702. As the water flow increases, more fine sand falls. S2. Furthermore, as the water flow increases, the water level on one side of the baffle 3 changes under the action of the baffle 707. Since the float 710 is located on the water surface, the float 710 moves to a certain extent as the water level changes. At the same time, when the float 710 moves, it can squeeze the sliding frame 708 through the connecting column 709, causing the sliding frame 708 to move and further pull the slide plate 704, thereby ensuring that the slide plate 704 can move a sufficient distance. S3. During sand feeding, the water flow and the micro-sand falling over the partition 3 will land inside the receiving bin 807. The motor 809 will then drive the mixing rod 808 to rotate, mixing the water flow and micro-sand to ensure better mixing and achieve the desired effect. Furthermore, the rotation of the mixing rod 808 will drive the second pulley 806 to rotate, which in turn drives the first pulley 804 to rotate via the belt 805. The first pulley 804 will then drive the reciprocating screw 803 to rotate. Since the pusher frame 801 has a slider in the through hole at one end that corresponds to the spiral groove on the outer wall of the reciprocating screw 803, the rotation of the reciprocating screw 803 will move the pusher frame 801. This will move the micro-sand inside the sand feeding bin 702 to ensure that the micro-sand is evenly distributed inside the sand feeding bin 702 and falls evenly during sand feeding. S4. When the wastewater enters the sludge removal chamber 5 after flocculation, the flocculated material can be blocked by the shielding frame 609 and the swing plate 607 to prevent it from being discharged with the water flow. The sludge settled at the bottom of the sludge removal chamber 5 can be discharged. Furthermore, depending on the size of the water flow and the amount of sediment, the connecting frame 602 can be moved by the electric push rod 601, which in turn moves the fixed rod 603 and the fixed frame 604. Since the upper and lower sides of the actuating plate 606 are equipped with limit rods 605, when the connecting frame 602 moves the shielding frame 609, the swing frame can be moved by the limit rods 605 to change the angle of the swing frame. At the same time, the distance between the swing frame and the shielding frame 609 can be adjusted, thereby achieving a good shielding effect under different water flow and flocculation conditions, thus preventing the flocculated material from being discharged with the water flow.

The micro-sand-assisted coagulation and sedimentation water treatment equipment according to claim 8, characterized in that, The shielding component (6) further includes: A swing plate (607) is rotatably mounted on both sides of a fixed plate (608), and a lever plate (606) is mounted at both ends of the swing plate (607). A shielding frame (609) is installed at the bottom of the connecting frame (602), and multiple shielding frames (609) are evenly arranged, and all shielding frames (609) are located between the fixing plates (608); A fixing rod (603) is installed at the bottom end of the connecting frame (602), and a fixing frame (604) is installed at the bottom end of the fixing rod (603). Limiting rod (605) is installed on one side of the fixed frame (604), and limiting rods (605) are provided on both the upper and lower sides of the actuating plate (606).
10. A micro-sand-assisted coagulation sedimentation water treatment device and its method of use according to any one of claims 1-9, characterized in that, Includes the following steps: S1. During the sedimentation process of wastewater, as the water flows into the sedimentation tank (2) through the inlet pipe (1), it gradually passes through the spaces separated by the internal partitions (3) of the sedimentation tank (2). When the water flows through the first partition (3) and enters the second space, the fine sand can leak out through the opening at the bottom of the sand feeding chamber (702) to mix with the water flow. Furthermore, when the water flows over the top of the partition (3), the water flow will impact the baffle (707), and as the water flows through the top of the partition (3), it will impact the baffle (707). As the water flow increases, the impact on the baffle (707) increases, which in turn causes the baffle (707) to rotate. As the baffle (707) rotates, it drives the gear (706) to rotate. Through the connection between the gear (706) and the rack (705), the slide plate (704) moves, thereby changing the area of the slide plate (704) covering the bottom opening of the sand feeding bin (702). As the water flow increases, more fine sand falls. S2. Furthermore, as the water flow increases, the water level on one side of the partition (3) changes under the action of the baffle (707). Since the float (710) is located on the water surface, the float (710) moves to a certain extent as the water level changes. At the same time, when the float (710) moves, it can squeeze the sliding frame (708) through the connecting column (709), causing the sliding frame (708) to move and further pull the slide plate (704), thereby ensuring that the slide plate (704) can move a sufficient distance. S3. During sand feeding, the water flow, as it passes over the partition (3) and falls, will land inside the receiving hopper (807). The motor (809) will then drive the mixing rod (808) to rotate, mixing the water flow and the sand to ensure better mixing and that the sand achieves its intended effect. Furthermore, the rotation of the mixing rod (808) will drive the second pulley (806) to rotate, and via the belt (805), drive the first... The pulley (804) rotates to drive the reciprocating screw (803) to rotate. Since the through hole at one end of the push frame (801) is provided with a slider corresponding to the spiral groove on the outer wall of the reciprocating screw (803), the push frame (801) can be moved when the reciprocating screw (803) rotates. In this way, the push frame (801) moves the micro-sand inside the sand feeding bin (702) to ensure that the micro-sand can be evenly distributed inside the sand feeding bin (702) and fall evenly when the sand is fed. S4. When the wastewater enters the sludge removal chamber (5) after flocculation, the flocculated material can be blocked by the baffle (609) and the swing plate (607) to prevent it from being discharged outward with the water flow. The sludge settled can be discharged by the sludge removal module at the bottom of the sludge removal chamber (5). Furthermore, depending on the size of the water flow and the amount of sediment, the connecting frame (602) can be moved by the electric push rod (601) to move the fixed rod (603) and the fixed frame (607). 04) The device moves, and since the upper and lower sides of the actuating plate (606) are equipped with limit rods (605), when the connecting frame (602) moves the shielding frame (609), the limit rods (605) can push the swinging frame to move, thereby changing the angle of the swinging frame. At the same time, the distance between the swinging frame and the shielding frame (609) can be adjusted, so as to achieve a good shielding effect under different water flow and flocculation conditions, thereby preventing flocculation from being discharged with the water flow.
