Description

Technical Field

[0001] The present invention relates to a sewage purification treatment device, in particular to an adjustable plankton interception sewage purification treatment device, belonging to the technical field of sewage purification. Background Art

[0002] Intercepting plankton in water has multiple significant advantages for sewage purification treatment. Currently, a planar net is used to intercept plankton. The interception area of the net is fixed during use, and the aperture size is also fixed. During use, it is impossible to dynamically correct the aperture and adjust the interception area, which easily leads to the situation of mesh blockage. Moreover, in windy weather, the net is prone to tilting and floating, affecting the interception effect. In addition, during use, it is also impossible to self-clean the net, resulting in low practicability.

[0003] Therefore, an adjustable plankton interception sewage purification treatment device is designed to optimize the above problems. Summary of the Invention

[0004] The main purpose of the present invention is to provide an adjustable plankton interception sewage purification treatment device. By arranging corrugated metal strips between the tops and bottoms of adjacent vertical rods, and a filter screen is arranged between the upper and lower groups of corrugated metal strips. The filter screen is also distributed in a corrugated shape, so that the filter screen has a larger filtering area under the adjacent projection area. Moreover, the three-dimensional structure of the corrugations enables plankton to be not only intercepted on the surface of the filter screen, but also captured through inertial collision and diffusion deposition in the gaps between the wave crests and wave troughs, improving the filtering effect during use. At the same time, the undulation of the corrugations on the filter screen makes it easier for plankton to accumulate in the wave troughs rather than directly blocking the orifices, reducing the probability of local blockage. In addition, when the water flow is flowing at a high speed, the fluid has a pushing effect on the filter screen, and the filter screen expands in the water flow direction, dynamically adjusting the aperture. At this time, the filtering aperture becomes larger, improving the permeability and reducing the resistance to the liquid, ensuring the stable position of the device. By arranging a stability mechanism composed of a sliding hole, a sliding rod, a counterweight, a tension spring, a hidden groove, and a groove on the second floating plate, when the wind force is large, the air flow enters the interior of the sliding hole, controlling the sliding rod to drive the counterweight to move, changing the center of gravity on the second floating plate, which can effectively prevent the filter screen from tilting and ensure the interception effect in strong winds. By arranging a vibration mechanism composed of a reciprocating screw rod, a fan blade, a protective cover, a first installation groove, a slider, a second installation groove, an impact block, a guide rod, a sliding groove, an insertion block, and a return spring between the second baffle and the vertical rod, when the wind force is large, the fan blade can be driven to rotate by the wind force, and the reciprocating screw rod controls the up and down movement of the slider. During the upward movement, the impact block is lifted, and after reaching the highest position, the impact block is released. The rapid downward movement of the impact block can control the overall vibration of the device, vibrating and cleaning the surface of the filter screen, improving the functionality and use effect of the device.

At the same time, the undulation of the corrugations on the filter screen makes it easier for plankton to accumulate in the wave troughs rather than directly blocking the orifices, reducing the probability of local blockage. In addition, when the water flow is flowing at a high speed, the fluid has a pushing effect on the filter screen, and the filter screen expands in the water flow direction, dynamically adjusting the pore diameter.

[0018] To make the technical solutions of the present invention clearer and more definite for those skilled in the art, the present invention will be further described in detail below in conjunction with embodiments and drawings, but the implementation manners of the present invention are not limited thereto.

[0019] As Figures 1 - 8 shown, this embodiment provides an adjustable plankton interception sewage purification treatment device, including a cable 1. There are two groups of cables 1, and the two groups of cables 1 are parallel to each other. A positioning mechanism 2 is provided at the end of the cable 1. The first floating plates 3 are evenly arranged between the two groups of cables 1 along the length direction. The second floating plates 4 are evenly fixed on the top of the two groups of first floating plates 3. Vertical rods 5 are vertically installed at the middle positions of the bottoms of the second floating plates 4. Corrugated metal strips 6 are provided between the tops and bottoms of the two groups of vertical rods 5. The corrugated metal strips 6 are made of 304 stainless steel or corrosion-resistant aluminum alloy, with a thickness of 2-5 mm and a yield strength ≥ 200 MPa to ensure stable shape and anti-rust under water flow impact. A filter screen 7 is provided between the two groups of corrugated metal strips 6. The filter screen 7 is made of nylon or polyester fiber woven mesh, with a pore size of 50-100 μm and a breaking strength ≥ 15 N / mm. The filter screen 7 has the same shape as the corrugated metal strip 6, with a peak height of 30-50 mm, a valley spacing of 80-120 mm, and a corrugation inclination angle of 45°-60° to balance the filtration area and water flow resistance. Stabilizing mechanisms 8 are provided on the sides of the second floating plates 4. A vibration mechanism 9 is provided between the top of the second floating plate 4 and the inside of the vertical rod 5.

[0020] Overall working principle: During use, the cable 1 spans across both sides of the river channel. The positioning mechanism 2 is used to fix the position of the cable 1. The first floating plate 3 and the second floating plate 4 on the cable 1 float on the liquid surface. The double-strand cable 1 can ensure the stability of the floating plates. The stabilizing mechanism 8 is close to the protected area. In the case of low water flow velocity, the water flow velocity < 0.5 m / s, the vertical rod 5 is vertical in the water, and the corrugated filter screen 7 intercepts the river channel. The filter screen 7 maintains its initial corrugated form with a pore diameter of 50 μm to intercept small particulate plankton. The stabilizing mechanism 8 is in the reset state, the center of gravity of the device is centered, and the plankton is intercepted in the gaps between the wave crests and wave troughs of the filter screen 7. When the wind and waves on the liquid surface are relatively large, the water flow velocity ≥ 1.5 m / s, the water flow will impact on the filter screen 7, and the filter screen 7 will expand and bulge in the direction of the water flow. At this time, the pore diameter of the filter screen 7 will become larger, and the corrugation spacing will expand by 10% - 20%, and the pore diameter will increase to 60 - 120 μm, improving the permeability. It can release smaller plankton, reduce the resistance of the water flow, and ensure the stability of the installation position of the device. At this time, the filter screen 7 receives a large thrust, and the stabilizing mechanism 8 is activated to adjust the center of gravity of the device to prevent the vertical rod 5 and the filter screen 7 from tilting towards the intercepted protected area, ensuring the interception and filtration effect. In addition, when the wind force is relatively large, it will drive the vibration mechanism 9 to operate, controlling the vertical rod 5 to vibrate downward. When the vertical rod 5 vibrates, it will also control the shaking of the filter screen 7, which can shake off the plankton to avoid the aggregation of plankton and ensure the permeability of the filter screen 7. When the wind and waves are relatively small, the filter screen 7 will reset under the elastic force of the corrugated metal strip 6 and return to its original state.

[0021] In this embodiment, hanging rings 10 are uniformly fixed between the filter screen 7 and the corrugated metal strip 6. The hanging rings 10 are distributed on the wave crests, wave troughs, and hypotenuses of the corrugated metal strip 6. The surface tension of the net is adjusted to 10 - 15 N / m through the hanging rings 10 to ensure the stability of the corrugated form.

[0022] Local working principle: The filter screen 7 and the corrugated metal strip 6 are uniformly fixed to ensure that the filter screen 7 and the corrugated metal strip 6 have the same shape.

[0023] In this embodiment, a perforation is provided between the two ends of the first floating plate 3, and the cable 1 passes through the inside of the perforation. Positioning screws are installed above the perforation at the top of the first floating plate 3. The diameter of the perforation is 2 - 3 mm larger than the outer diameter of the cable 1. 2 - 4 positioning screws M4 - M6 are uniformly arranged along the circumferential direction of the perforation, and the tightening torque is 8 - 10 N·m to ensure that the floating plate can slide along the cable 1 and be locked.

[0024] Local working principle: During the assembly of the device, the cable 1 is passed through the inside of the first floating plate 3, and then limited by the positioning screws to ensure the installation stability of the first floating plate 3.

[0025] In this embodiment, the positioning mechanism 2 includes a positioning column 201, a strip-shaped groove 202, and a mounting block 203. The positioning column 201 is vertically fixed on the shore. A strip-shaped groove 202 is vertically formed on the positioning column 201. A mounting block 203 is slidably disposed inside the strip-shaped groove 202. The end of the cable 1 is fixed to the mounting block 203. The height of the strip-shaped groove 202 is 1.5 - 2 m, which is adapted to the water level fluctuation range. The fitting clearance between the mounting block 203 and the strip-shaped groove 202 is 0.5 - 1 mm. A dovetail groove is used for guiding to prevent the cable 1 from swaying horizontally.

[0026] Local working principle: When fixing the device, the positioning column 201 is vertically fixed on the shore. After the liquid level rises, the cable 1 will drive the mounting block 203 to slide vertically inside the strip-shaped groove 202 to ensure that the device always intercepts on the liquid surface.

[0027] In this embodiment, the stabilizing mechanism 8 includes a sliding hole 801, a sliding rod 802, a counterweight 803, and a tension spring 804. The sliding holes 801 are formed on both sides of the second floating plate 4 and penetrate through the second floating plate 4. Sliding rods 802 are slidably disposed inside the sliding holes 801. A counterweight 803 is fixed between the ends of the two groups of sliding rods 802. The counterweight 803 is made of cast iron or lead alloy, with a mass of 5 - 10 kg, accounting for 20% - 30% of the total mass of the second floating plate 4, ensuring a significant center-of-gravity adjustment effect. A tension spring 804 is provided between the middle position of the counterweight 803 and the second floating plate 4.

[0028] Local working principle: When the wind force is large, i.e., wind speed ≥ 8 m / s, the airflow enters the inside of the sliding hole 801, pushing the sliding rod 802 to slide. The sliding rod 802 drives the counterweight 803 to slide away from the second floating plate 4. At this time, the counterweight 803 slides to the maximum stroke (80% of the length of the sliding hole 801). The balance of the floating plate is maintained by the tension (50 - 80 N) of the tension spring 804, changing the position of the center of gravity on the second floating plate 4, resisting the thrust of the wind and waves, preventing the filter screen 7 from tilting, and improving the vertical stability of the vertical rod 5. When the counterweight 803 moves, the tension spring 804 will be stretched. When the wind speed slows down, the tension spring 804 controls the counterweight 803 to reset.

[0029] In this embodiment, the outer side surface of the counterweight 803 is arc-shaped. A hidden groove 805 matching the counterweight 803 is formed on the second floating plate 4. The counterweight 803 is located inside the hidden groove 805. A groove 806 is formed at the inner end of the hidden groove 805. One end of the tension spring 804 is located at the inner end of the groove 806.

[0030] Local working principle: In the initial state, the counterweight 803 is stored inside the hidden groove 805. The outer side of the counterweight 803 and the outer side of the second floating plate 4 are on the same circumferential surface, making the device more beautiful.

[0031] In this embodiment, the vibration mechanism 9 includes a second installation groove 906, an impact block 907 and a lifting and releasing assembly. The second installation grooves 906 are symmetrically formed on both sides inside the vertical rod 5. Impact blocks 907 are vertically and slidably arranged inside the second installation grooves 906. A lifting and releasing assembly is provided at the middle position of the vertical rod 5.

[0032] Local working principle: During the process of vibration cleaning, the lifting and releasing assembly controls the impact block 907 to move upward. After the impact block 907 moves to the top of the second installation groove 906, the impact block 907 is released, and the impact block 907 impacts the bottom end of the second installation groove 906 to control the shaking of the vertical rod 5.

[0033] In this embodiment, the lifting and releasing assembly includes a reciprocating lead screw 901, a first installation groove 904, a slider 905, a guide rod 908, a rotating part and a limiting member 909. The reciprocating lead screw 901 is rotatably installed at the middle position inside the vertical rod 5. The top end of the reciprocating lead screw 901 penetrates through the second floating plate 4 and is rotatably connected to the second floating plate 4. A rotating part is provided at the top end of the reciprocating lead screw 901. A first installation groove 904 is vertically formed inside the vertical rod 5. The first installation groove 904 is located between the two groups of second installation grooves 906, and the length of the first installation groove 904 is greater than the length of the second installation groove 906. A slider 905 is provided on the reciprocating lead screw 901 and inside the first installation groove 904. A guide rod 908 is fixed between the upper and lower ends of the first installation groove 904. The guide rod 908 is slidably connected to the slider 905. A limiting member 909 is provided between the slider 905 and the impact block 907.

[0034] Local working principle: When lifting the impact block 907, the rotation of the reciprocating lead screw 901 is controlled by the rotating part to move the slider 905 to the bottom end of the impact block 907, and then the upward movement of the slider 905 is controlled. At this time, the limiting member 909 is located at the bottom of the impact block 907, and the supporting force of the limiting member 909 on the impact block 907 is greater than the gravity of the impact block 907. Therefore, during the upward movement of the slider 905, the impact block 907 will be controlled to move upward. After the impact block 907 moves to the top of the second installation groove 906, the top end of the second installation groove 906 blocks the impact block 907. At this time, the limiting member 909 retracts into the slider 905, and the impact block 907 loses the supporting force and automatically slides downward.

[0035] In this embodiment, the rotating part includes a fan blade 902 and a shroud 903. The fan blade 902 is fixed at the top of the reciprocating lead screw 901. A shroud 903 is provided outside the fan blade 902. The starting wind speed of the fan blade 902 is 3 - 5 m / s, the blade area is 0.1 - 0.2 m², and the rotational speed is positively correlated with the wind speed (rotational speed = wind speed × 20 r / (m·s⁻¹)) to ensure the reliability of wind power drive.

[0036] Local working principle: In the case of strong wind, the wind speed ≥ 8 m / s, the wind power controls the rotation of the fan blade 902, driving the reciprocating lead screw 901 to rotate, without the need for electric drive, which is energy-saving and convenient. The rotation speed of the fan blade 902 driving the reciprocating lead screw 901 is ≥ 50 r / min, the lifting speed of the slider 905 is 100 mm / s, the mass of the impact block 907 is 2 - 3 kg, the falling impact frequency is 1 - 2 times / minute, and the vibration amplitude is 5 - 10 mm, ensuring the effective detachment of the attachments on the surface of the filter screen 7.

[0037] In this embodiment, the limiting member 909 includes a chute 9091, a plug 9092, and a return spring 9093. The chutes 9091 are symmetrically formed on the sides of the slider 905. Plug blocks 9092 are slidably arranged inside the chutes 9091. The ends of the plug blocks 9092 are symmetrically provided with inclined surfaces up and down. A return spring 9093 is provided between the ends of the plug blocks 9092 and the chutes 9091.

[0038] Local working principle: When the impact block 907 is at the bottom of the second installation groove 906, the slider 905 drives the plug block 9092 to move downward. After the inclined surface at the bottom of the plug block 9092 contacts the impact block 907, as the slider 905 continues to move downward, the plug block 9092 will be squeezed into the interior of the chute 9091 until the plug block 9092 moves to the bottom of the impact block 907. The plug block 9092 is reset under the action of the return spring 9093, and the impact block 907 protrudes inside the first installation groove 904. Therefore, during the upward movement of the slider 905, the plug block 9092 can contact the bottom of the impact block 907 to control the upward movement of the impact block 907.

[0039] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent replacements or changes, all belong to the protection scope of the present invention.
