Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a wind-powered foam collection and purification device for water treatment. Background Technology

[0002] In water treatment processes, ultrafiltration membranes effectively remove suspended solids, colloids, bacteria, viruses, and other large molecules from water, significantly improving water clarity and safety. In drinking water treatment, ultrafiltration technology removes harmful substances, ensuring people's healthy drinking water needs. Furthermore, ultrafiltration technology can significantly remove harmful substances from water, reducing or eliminating the need for chemical agents, thus effectively preventing secondary pollution and ensuring the treated water is pure and flawless. During the use of ultrafiltration membrane tanks, a large amount of foam is generated in the ultrafiltration water. This foam, which is on the liquid surface, seriously affects the continuous ultrafiltration effect and sometimes causes backflow. Therefore, it is necessary to collect and purify the foam. Existing ultrafiltration membrane tanks are not convenient for efficient and continuous collection and purification of foam, and lack effective centralized capture and cleaning methods, resulting in a large accumulation of foam and affecting the water treatment effect.

[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 wind-powered foam collection and purification device for water treatment, which solves the problem that existing ultrafiltration membrane tanks are inconvenient for efficient and continuous foam collection and purification. The technical solution of this invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wind-powered foam collection and purification device for water treatment, comprising an ultrafiltration membrane tank, a fan, a collection tank, and a three-stage filtration purifier; It also includes an installation frame, which is vertically and movably installed on both sides of the inner wall of the ultrafiltration membrane tank via an electric push rod. A reciprocating screw is installed in the inner cavity of the installation frame via a motor. A movable seat is threaded on the reciprocating screw. A pusher cylinder is rotatably installed at the inner end of the movable seat. A pusher seat is fixed on the outer side of the pusher cylinder. A pusher plate is connected to the outer cavity of the pusher seat via an elastic telescopic rod. A bidirectional pushing component includes a toothed sleeve, which is slidably fitted onto both ends of a pushing cylinder. A rack is provided at both the upper and lower positions of the toothed sleeve, and the rack is fixed to the side wall of the mounting frame. A first positioning plate and a second positioning plate are respectively provided at both ends of the toothed sleeve's movement trajectory, and both the first positioning plate and the second positioning plate are fixed to the side wall of the mounting frame. A fixed-point pushing component is disposed inside the pushing cylinder and between the mounting frame, and the fixed-point pushing component is used to push the bottom pushing plate out.

[0006] Preferably, a fan is vertically mounted on the left end of the ultrafiltration membrane tank via an electric push rod, a collection tank is fixed on the right end of the ultrafiltration membrane tank, and a three-stage filtration purifier is installed on the outside of the right end of the ultrafiltration membrane tank.

[0007] Preferably, the input and output ends of the three-stage filtration purifier are connected to the collection tank and the ultrafiltration membrane tank respectively via a negative pressure pump, and the collection tank is designed as an embedded structure.

[0008] Preferably, the push seats are distributed at equal angles on the outside of the push cylinder, the cross-section of the push plate inside the push seat is a "T" shaped structure, and the outer end of the push plate extends out of the push seat.

[0009] Preferably, the upper and lower racks are staggered, and the upper and lower racks respectively mesh with the moved gear sleeve.

[0010] Preferably, the ends of the first positioning plate and the second positioning plate are both designed as inclined structures that abut against the outer and inner sides of the tooth sleeve, respectively, and the top view cross section of the first positioning plate is designed as an "L" shaped structure.

[0011] Preferably, the fixed-point pushing component includes a horizontal bar that is longitudinally installed inside the pushing cylinder. A push block is fixed to the outside of the horizontal bar and slides elastically inside the pushing cylinder by a spring. A vertical rod is abutted against the outside of the push block and the vertical rod is fixed to the inside of the pushing plate. A push strip is provided at the outer end of the horizontal bar's movement trajectory and is fixed to the side wall of the mounting frame.

[0012] Preferably, the cross-section of the push block is designed as a right-angled trapezoidal structure, and the inclined surface at the outer end of the push block abuts against the vertical rod.

[0013] Preferably, the push bar is designed as an arc-shaped structure, the push bars are evenly distributed on the mounting frame, and the inner side of the push bar is designed as an inclined structure that abuts against the crossbar.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when treating wastewater, ultrafiltration is performed in an ultrafiltration membrane tank. The scum on the ultrafiltration membrane is blown to a collection tank by a fan, and the scum and a small amount of water are pumped to a three-stage filtration purifier by a negative pressure pump for filtration. The filtered water re-enters the ultrafiltration membrane tank to treat the scum. At the same time, a reciprocating screw driven by a motor rotates, causing the pusher cylinder to move back and forth. During this process, the toothed sleeve meshes with the upper and lower racks respectively, so that the pusher cylinder can rotate counterclockwise during the reciprocating movement. In conjunction with the fan, the efficiency of scum capture and pushing is improved. 2. In this invention, the pusher cylinder, during its reciprocating motion and counterclockwise rotation, drives the pusher seat to rotate. This, in conjunction with the pusher bar, horizontal bar, pusher block, and vertical bar, causes the pusher plate to extend and retract. Just before contacting the foam, the pusher plate extends, pushing the foam forward. As it is about to separate from the foam surface, the pusher plate retracts, ensuring unidirectional pushing of the foam. During this process, the reciprocating motion and unidirectional rotation of the pusher cylinder maintain continuous pushing of the foam, greatly improving the foam collection efficiency and thus enhancing the water treatment effect of the ultrafiltration membrane tank.

[0017] 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.

[0018] Please see Figures 1-8This invention provides a technical solution: a wind-powered foam collection and purification device for water treatment, comprising an ultrafiltration membrane tank 1, a fan 2, a collection tank 3, a three-stage filter purifier 4, a mounting frame 5, a reciprocating screw 6, a movable seat 7, a pusher cylinder 8, a pusher seat 9, an elastic telescopic rod 10, a pusher plate 11, a toothed sleeve 121, a rack 122, a first positioning plate 123, a second positioning plate 124, a horizontal bar 131, a pusher block 132, a vertical rod 133, and a pusher bar 134. Example 1: Please refer to Figures 1-6 It includes an ultrafiltration membrane tank 1, a fan 2, a collection tank 3, and a three-stage filtration purifier 4; the fan 2 is vertically mounted on the left side of the ultrafiltration membrane tank 1 via an electric push rod, the collection tank 3 is fixed on the right side of the ultrafiltration membrane tank 1, and the three-stage filtration purifier 4 is installed on the outside of the right side of the ultrafiltration membrane tank 1; the input and output ends of the three-stage filtration purifier 4 are connected to the collection tank 3 and the ultrafiltration membrane tank 1 respectively via a negative pressure pump, and the collection tank 3 is designed as an embedded structure; The foam on the ultrafiltration membrane tank 1 is blown by the fan 2 into the collection tank 3. The foam and a small amount of water are then pumped to the three-stage filtration purifier 4 for filtration by the negative pressure pump. The filtered water then re-enters the ultrafiltration membrane tank 1.

[0019] The mounting frame 5 is vertically and movably installed on both sides of the inner wall of the ultrafiltration membrane tank 1 via an electric push rod. A reciprocating screw 6 is installed in the inner cavity of the mounting frame 5 via a motor. A movable seat 7 is threaded onto the reciprocating screw 6. A pusher cylinder 8 is rotatably installed at the inner end of the movable seat 7. A pusher seat 9 is fixed to the outer side of the pusher cylinder 8. A pusher plate 11 is connected to the outer cavity of the pusher seat 9 via an elastic telescopic rod 10. The bidirectional pusher assembly includes a toothed sleeve 121, which is slidably fitted onto both ends of the pusher cylinder 8. A rack 122 is provided at both the upper and lower positions of the toothed sleeve 121. The rack 122 is fixed to the side wall of the mounting frame 5. The two ends of the toothed sleeve 121's movement path are respectively equipped with... The device includes a first positioning plate 123 and a second positioning plate 124, both of which are fixed to the side wall of the mounting frame 5. A pusher seat 9 is distributed at equal angles on the outside of the pusher cylinder 8. The pusher plate 11 inside the pusher seat 9 has a "T"-shaped cross-section, with the outer end of the pusher plate 11 extending out of the pusher seat 9. Two upper and lower racks 122 are staggered and mesh with the moved gear sleeve 121, respectively. The ends of the first positioning plate 123 and the second positioning plate 124 are designed as inclined surfaces that abut against the outer and inner sides of the gear sleeve 121, respectively. The top view cross-section of the first positioning plate 123 is designed as an "L"-shaped structure. The reciprocating screw 6, driven by a motor, rotates within the inner cavity of the mounting frame 5, causing the movable seat 7 to slide within the inner cavity of the mounting frame 5. This, in turn, moves the pusher cylinder 8. During the movement of the pusher cylinder 8, the toothed sleeve 121 first engages with the upper rack 122, causing the pusher cylinder 8 to rotate counterclockwise on the movable seat 7. This, in turn, causes the pusher seat 9 and the pusher plate 11 to rotate. When the pusher cylinder 8 moves to the far right and begins to reset, the toothed sleeve 121 contacts the inclined surface of the second positioning plate 124, which can push the toothed sleeve 121 towards the center, causing the toothed sleeve 121 to engage with the bottom rack 122. At this time, when the pusher cylinder 8 resets, the rack 122 still drives the pusher cylinder 8 to rotate counterclockwise through the toothed sleeve 121, pushing the foam in the same direction again.

[0020] Example 2: Please refer to Figures 1-4 and Figures 7-8 A fixed-point pushing component is disposed between the pushing cylinder 8 and the mounting frame 5. The fixed-point pushing component is used to push the bottom pushing plate 11 out. The fixed-point pushing component includes a horizontal bar 131, which is installed longitudinally through the pushing cylinder 8. A push block 132 is fixed on the outside of the horizontal bar 131. The push block 132 slides elastically in the pushing cylinder 8 by a spring. A vertical rod 133 is abutted on the outside of the push block 132. The vertical rod 133 is fixed on the inside of the pushing plate 11. A push strip 134 is provided at the outer end of the movement path of the horizontal bar 131. The push strip 134 is fixed on the side wall of the mounting frame 5. The cross-section of the push block 132 is designed as a right-angled trapezoidal structure. The inclined surface of the outer end of the push block 132 abuts against the vertical rod 133. The push strip 134 is designed as an arc structure. The push strips 134 are evenly distributed on the mounting frame 5. The inner surface of the push strip 134 is designed as an inclined structure and abuts against the horizontal bar 131. When the horizontal bar 131 inside the pusher cylinder 8 moves to the lower left area, it contacts the pusher bar 134. The inclined structure of the pusher bar 134 drives the horizontal bar 131 to move inward at the pusher cylinder 8, thereby driving the pusher block 132 to move. The inclined surface of the pusher block 132 abuts against the vertical rod 133, and the vertical rod 133 pushes out the pusher plate 11, so that the pusher plate 11 can rotate and push out during the movement, pushing the foam towards the collection tank 3. When the horizontal bar 131 separates from the pusher bar 134, the pusher plate 11 and the horizontal bar 131 are reset under the action of the spring and the elastic telescopic rod 10. That is, when the pusher plate 11 passes the bottom, it retracts and resets, preventing the foam from being carried to the top.

[0021] Working principle: First, when foam is generated at the liquid surface in the ultrafiltration membrane tank 1, the height of the fan 2 and the mounting bracket 5 is adjusted according to the liquid level. Then, the fan 2 is started to blow away the foam, and the reciprocating screw 6 is driven by the motor to rotate in the inner cavity of the mounting bracket 5, which in turn drives the movable seat 7 to slide in the inner cavity of the mounting bracket 5, thereby moving the pusher cylinder 8. During the movement of the pusher cylinder 8, the toothed sleeve 121 first engages with the upper rack 122, causing the pusher cylinder 8 to rotate counterclockwise on the movable seat 7, which in turn drives the pusher seat 9 and the pusher plate 11 to rotate. When the horizontal bar 131 inside the pusher cylinder 8 moves to the lower left area, it contacts the pusher bar 134. Through the inclined structure of the pusher bar 134, the horizontal bar 131 moves inward at the pusher cylinder 8. This causes the pusher block 132 to move. The inclined surface of the pusher block 132 abuts against the vertical rod 133, and the pusher plate 11 is pushed out through the vertical rod 133. This allows the pusher plate 11 to rotate and push out during the movement, pushing the foam towards the collection tank 3. When the horizontal bar 131 separates from the pusher bar 134, the pusher plate 11 and the horizontal bar 131 are reset under the action of the spring and the elastic telescopic rod 10. That is, when the pusher plate 11 passes the bottom, it retracts and resets to avoid carrying the foam to the top. As the pusher cylinder 8 continues to move, the above operation is repeated. With the help of the fan 2, the foam is pushed into the collection tank 3, and the foam and a small amount of water are pumped to the three-stage filter purifier 4 for filtration by the negative pressure pump. The filtered water re-enters the ultrafiltration membrane tank 1. When the pusher cylinder 8 moves to the rearmost side and begins to reset, the toothed sleeve 121 contacts the inclined surface of the second positioning plate 124, which can push the toothed sleeve 121 to move towards the center, so that the toothed sleeve 121 begins to mesh with the bottom rack 122. At this time, when the pusher cylinder 8 resets, the rack 122 still drives the pusher cylinder 8 to rotate counterclockwise through the toothed sleeve 121, pushing the foam in the same direction again, and cooperating with the crossbar 131 and the push bar 134 to realize the extension and retraction of the pusher plate 11. When the pusher cylinder 8 moves and resets, the toothed sleeve 121 contacts the inclined surface of the first positioning plate 123, so that the toothed sleeve 121 moves outward and resets, and then repeats the subsequent pushing operation.
