Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically relating to a water treatment device based on micro-nano bubble technology. Background Technology

[0002] Wastewater treatment is a crucial part of environmental governance. The purification and removal of impurities from water resources are related to people's daily lives, work, and production. With the advancement of technology, micro-nano bubble technology has begun to be applied to wastewater treatment. Micro-nano bubble technology introduces micro-nano bubbles into wastewater through a micro-nano bubble generator. The micro-nano bubbles carry impurities in the wastewater to the surface, thereby achieving the effect of removing impurities from the wastewater.

[0003] Although impurities in wastewater can be separated and removed using micro-nano bubble technology, these impurities still float on the surface of the liquid, making them difficult to clean. Therefore, we propose a water treatment device based on micro-nano bubble technology. Summary of the Invention

[0004] The purpose of this invention is to provide a water treatment device based on micro-nano bubble technology. By setting up a water surface collection mechanism, impurities floating on the water surface can be pushed to the left and right sides of the sewage tank and then the impurities gathered on the left and right sides of the sewage tank can be cleaned by a water surface cleaning mechanism, thereby conveniently removing impurities floating on the liquid surface.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A water treatment device based on micro / nano bubble technology includes a micro / nano bubble generator and a wastewater tank. The micro / nano bubble generator is connected to an outlet pipe extending to the lower end of the wastewater tank. The wastewater tank is also equipped with an inlet pipe and an outlet pipe. The wastewater tank is further equipped with a surface sludge collection mechanism and a surface sludge cleaning mechanism. The water surface sewage collection mechanism includes two sewage pushers and a first transmission component. The two sewage pushers are arranged side by side in the middle of the upper part of the sewage tank and are slidably connected to the sewage tank. The front and rear ends of the two sewage pushers are also fixedly connected with limiting connecting rods that match the upper wall of the sewage tank. The first transmission component is fixedly installed on the front wall of the sewage tank and is used to push the two limiting connecting rods on the front side away from each other or close to each other. The water surface cleaning mechanism includes two cleaning screens and two collection boxes. The two cleaning screens are vertically arranged at the left and right ends of the sewage tank. The upper left and right sides of the sewage tank are fixedly connected to hinge platforms. The two hinge platforms are rotatably connected to first rotating shafts. The two cleaning screens are fixedly connected to the two first rotating shafts. The two collection boxes are fixedly installed on the outer walls of the left and right ends of the sewage tank. The upper width of the collection box matches the width of the cleaning screen. A second transmission component is also provided on the rear wall of the sewage tank. The second transmission component is used to drive the two first rotating shafts to rotate in opposite directions.

[0006] The first transmission assembly includes a dual-axis motor, screws, and connecting plates. There are two screws, which are fixedly connected to the output shafts on both sides of the dual-axis motor. The two screws have opposite thread directions. There are two connecting plates, which are fixedly connected to the two limiting connecting rods on the front side. The two connecting plates are rotatably connected to the two screws respectively.

[0007] The second transmission assembly includes a servo motor, a drive gear, a transmission gear, a transmission pulley, and a driven pulley. The output shaft of the servo motor is fixedly connected to the drive gear. Two second rotating shafts are rotatably connected to the rear wall of the sewage tank, arranged left and right. There are two transmission gears, each fixedly connected to one of the two second rotating shafts and meshing with each other. The drive gear meshes with one of the transmission gears. There are two transmission pulleys, each fixedly connected to one of the two second rotating shafts. There are two driven pulleys, each fixedly connected to the end of one of the two first rotating shafts. The transmission pulleys and driven pulleys on the same side are connected by a belt drive.

[0008] The ratio of the number of teeth of the transmission gear to the number of teeth of the driving gear is not less than 2.

[0009] The extension lengths of the two limiting connecting rods on the left and right sides of the pushing plate are matched with the width of the cleaning screen plate.

[0010] The upper ends of the sludge collection boxes on both the left and right sides are fixedly provided with a first right-angle cover, and the upper ends of the two sludge push plates on the left and right sides are fixedly provided with a second right-angle cover that matches the limiting connecting rod. The first right-angle cover on the same side matches the second right-angle cover.

[0011] Several equidistant plastic pads are also installed on the lower inner walls of the first right-angle cover on both the left and right sides. The cleaning screen plate is made of thin-walled iron sheet and coated with anti-corrosion and anti-rust coating.

[0012] The inlet pipe is also equipped with a filter, and both the inlet pipe and the outlet pipe are controlled by valves.

[0013] Both the first transmission component and the second transmission component also include a protective housing.

[0014] When using the device, sewage is introduced through the inlet pipe. After the sewage tank is full, the micro-nano bubble generator is activated. The micro-nano bubbles enter the sewage tank through the outlet pipe. The micro-nano bubbles adsorb impurities in the water, causing the impurities to float to the surface, thereby purifying the sewage and significantly improving its quality. When a large amount of impurities accumulate on the sewage surface, the surface collection mechanism is activated. Two pusher plates push the impurities on the sewage surface to the left and right sides of the sewage tank. After the impurities on the sewage surface are concentrated to the left and right sides of the sewage tank, the surface cleaning mechanism is activated. Two cleaning screens flip upwards simultaneously, carrying the impurities concentrated on the left and right sides out of the sewage tank until the cleaning screens flip to the collection box, where the impurities fall into the collection box. After the impurities are cleaned, the surface collection mechanism and the surface cleaning mechanism are returned to their initial state, and then the drain pipe is opened to discharge the treated water.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0018] like Figures 1 to 3 The water treatment device based on micro-nano bubble technology shown includes a micro-nano bubble generator 100 and a sewage tank 101. The micro-nano bubble generator 100 is connected to an outlet pipe 102 extending to the lower end of the sewage tank 101. The sewage tank 101 is also provided with an inlet pipe 103 and an outlet pipe 104. The sewage tank 101 is also equipped with a water surface collection mechanism and a water surface cleaning mechanism. The water surface sewage collection mechanism includes two sewage pushers 105 and a first transmission component. The two sewage pushers 105 are arranged side by side in the middle of the upper end of the sewage tank 101 and are slidably connected to the sewage tank 101. The front and rear ends of the two sewage pushers 105 are also fixedly connected with limiting connecting rods 106 that match the upper wall of the sewage tank 101. The first transmission component is fixedly installed on the front wall of the sewage tank 101 and is used to push the two limiting connecting rods 106 on the front side away from each other or close to each other. The first transmission assembly includes a dual-axis motor 111, screws 112, and connecting plates 113. There are two screws 112, which are fixedly connected to the output shafts on both sides of the dual-axis motor 111 respectively. The threads of the two screws 112 are opposite. There are two connecting plates 113, which are fixedly connected to the two limit connecting rods 106 on the front side respectively. The two connecting plates 113 are rotatably connected to the two screws 112 respectively. The water surface cleaning mechanism includes two cleaning screens 107 and two collection boxes 108. The two cleaning screens 107 are vertically arranged at the left and right ends of the sewage tank 101. The left and right sides of the upper end of the sewage tank 101 are fixedly connected to hinge platforms 109. The two hinge platforms 109 are rotatably connected to the first rotating shafts 110. The two cleaning screens 107 are fixedly connected to the two first rotating shafts 110 respectively. The two collection boxes 108 are fixedly installed on the outer walls of the left and right ends of the sewage tank 101 respectively. The upper width of the collection box 108 matches the width of the cleaning screens 107. The rear side wall of the sewage tank 101 is also provided with a second transmission component, which is used to drive the two first rotating shafts 110 to rotate in opposite directions. The second transmission assembly includes a servo motor 114, a drive gear 115, a transmission gear 116, a transmission pulley 117, and a driven pulley 118. The output shaft of the servo motor 114 is fixedly connected to the drive gear 115. Two second rotating shafts 119 are rotatably connected to the rear wall of the sewage tank 101. There are two transmission gears 116, which are fixedly connected to the two second rotating shafts 119 respectively. The two transmission gears 116 mesh with each other. The drive gear 115 meshes with one of the transmission gears 116. There are two transmission pulleys 117, which are fixedly connected to the two second rotating shafts 119 respectively. There are two driven pulleys 118, which are fixedly connected to the ends of the two first rotating shafts 110 respectively. The transmission pulleys 117 and driven pulleys 118 on the same side are connected by belt drive.

[0019] Wastewater enters the wastewater tank 101 through the inlet pipe 103. A micro-nano bubble generator produces micro-nano bubbles, which are then introduced into the wastewater tank 101 through the outlet pipe 102 to treat the wastewater. The micro-nano bubbles adsorb impurities in the water, causing them to float to the surface, thus purifying the wastewater. A surface collection mechanism collects impurities from the water surface, while a surface cleaning mechanism removes these collected impurities. The working principle of the surface collection mechanism is as follows: It is started by the dual-shaft motor 111 of the first transmission component, enabling... The two screws 112 rotate. Since the two screws 112 are threadedly connected to the two connecting plates 113 respectively, and the threads rotate in opposite directions, the rotation of the two screws 112 causes the two connecting plates 113 to move away from each other. Furthermore, since the two connecting plates 113 are fixed to the two front limiting connecting rods 106 respectively, the movement of the two connecting plates 113 away from each other causes the two pusher plates 105 to move away from each other, allowing the two pusher plates 105 to move from the center of the sewage tank 101 to the left and right sides respectively, thereby raising the water surface... The impurities are concentrated on the left and right sides of the sewage tank 101 respectively. The working principle of the water surface cleaning mechanism is as follows: the servo motor 114 of the second transmission component is started. The servo motor 114 is controlled by the servo system. When the servo motor receives one pulse, it will rotate by the angle corresponding to one pulse, thereby accurately controlling the number of rotations, rotation direction and rotation angle of the servo motor. After the servo motor 114 is started, the active gear 115 drives one of the transmission gears 116 to rotate. Since the two transmission gears 116 mesh, the rotation directions of the two transmission gears 116 are opposite. At the same time, under the transmission of the transmission pulley 117 and the driven pulley 118, the two first rotating shafts 110 can rotate in opposite directions, so that the cleaning screen plates 107 on the left and right sides flip upward synchronously, and carry the impurities concentrated on the left and right sides of the sewage tank 101 out of the sewage tank 101. Until the cleaning screen plates 107 on the left and right sides rotate to the collection boxes 108 on the left and right sides respectively, the servo motor 114 is controlled to stop rotating, and the impurities on the cleaning screen plates 107 can fall into the collection box 108. In the initial state of this device, such as Figure 1 and Figure 2 As shown, the two sludge-pushing plates 105 of the water surface sludge collection mechanism are arranged side by side and located in the middle of the sewage tank 101, while the two sludge-cleaning screen plates 107 of the water surface sludge cleaning mechanism are in a vertically downward state and are arranged side by side with the wall of the sewage tank 101. The following steps are included when using the device: ① In the initial state of the device, sewage is introduced through the inlet pipe 103. After the sewage fills the sewage tank 101, the micro-nano bubble generator 100 is started, and the micro-nano bubbles enter the sewage tank 101 through the outlet pipe 102. ② Impurities in the water are adsorbed by micro-nano bubbles, causing the impurities to float to the surface, thereby purifying the wastewater; ③ When the sewage quality is significantly improved and a large amount of impurities accumulate on the sewage surface, the sewage collection mechanism is activated. Through two sludge pushers 105, the impurities on the sewage surface are pushed and concentrated to the left and right sides of the sewage tank 101. ④ After impurities on the surface of the sewage pool gather to the left and right sides of the sewage tank 101, the surface cleaning mechanism is activated. The two cleaning screens 107 simultaneously flip upwards, carrying the gathered impurities out of the sewage pool 101. This continues until the cleaning screens 107 flip to the collection box 108, at which point the impurities fall into the collection box 108. Figure 3 As shown; ⑤ After the impurities are cleaned, return the water surface collection mechanism and the water surface cleaning mechanism to their initial state, and then open the drain pipe 104 to discharge the treated water.

[0020] As a further optimization in this embodiment, the gear ratio of the transmission gear 116 to the drive gear 115 is not less than 2. This setting can reduce the rotation speed of the second rotating shaft 119 and avoid the inertial impact caused by excessive rotation. Example

[0021] Based on Example 1, further optimizations were made, such as... Figures 4 to 5 As shown, the extension lengths of the two limiting connecting rods 106 of the push plate 105 on the left and right sides are matched with the width of the cleaning screen plate 107. The upper ends of the sludge collection boxes 108 on both the left and right sides are fixedly provided with a first right-angle cover 200, and the upper ends of the two sludge push plates 105 on the left and right sides are fixedly provided with a second right-angle cover 201 that matches the limiting connecting rod 106. The first right-angle cover 200 and the second right-angle cover 201 on the same side match. Several equidistant plastic pads 202 are installed on the lower inner wall of the first right-angle cover 200 on both the left and right sides. The cleaning screen plate 107 is made of thin-walled iron sheet and coated with anti-corrosion and anti-rust coating.

[0022] The extension length of the limiting connecting rod 106 is matched with the width of the cleaning screen plate 107. This allows the limiting connecting rod 106 to gradually approach the hinge table 109 when the two pushing plates 105 push impurities away from each other and concentrate them on the left and right sides of the sewage tank 101. After it abuts against the hinge table 109, the pushing plates 105 will no longer push the impurities. At this time, the concentration range of the impurities will match that of the cleaning screen plate 107, so that when the cleaning screen plate 107 rotates to clean, all the concentrated impurities can be carried out. The first right-angle cover 200 and the second right-angle cover 201, which are set up, will merge together after the two dirt-pushing plates 105 push away the impurities. Figure 5 As shown, when the two cleaning screens 107 rotate to clean, they can pass through the enclosed space formed by the first right-angle cover 200 and the second right-angle cover 201, thus preventing impurities from splashing due to centrifugal force. The cleaning screen plate 107 is made of thin-walled iron sheet and coated with an anti-corrosion and anti-rust coating, which can prevent the cleaning screen plate 107 from being rusted and corroded in sewage. At the same time, when the cleaning screen plate 107 rotates to the lower inner wall of the first right-angle cover 200, because the cleaning screen plate 107 is a thin-walled iron sheet, it can deform when it rotates to abut against the plastic pad 202. After separating from the plastic pad 202, it will spring back. Thus, the cleaning screen plate 107 can deform and spring back during the rotation of the lower inner wall of the first right-angle cover 200, which can further shake the impurities carried by the cleaning screen plate 107 into the collection box 108. Example

[0023] Based on Example 2, further functional optimizations were made, such as... Figure 6 As shown, the inlet pipe 103 is also equipped with a filter 300. Both the inlet pipe 103 and the drain pipe 104 are switched on and off by valves. The first transmission assembly and the second transmission assembly also include a protective shell 301.

[0024] The filter 300 is installed so that the sewage can undergo preliminary filtration before entering the sewage tank 101, removing large-volume debris. When sewage is introduced, the valve of the inlet pipe 103 is opened and the valve of the drain pipe 104 is closed. When the treated sewage is discharged, the valve of the drain pipe 104 is opened. The protective shell 301 is installed to protect the first transmission component and the second transmission component from damage due to collision.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
