Description

TECHNICAL FIELD

[0001] The present application relates to the sewage treatment filtering technical field, specifically a kind of vibration platform filtering device. BACKGROUND

[0002] In the sewage treatment process, in order to prevent the pollution of water body and soil in the environment caused by direct discharge of sewage, a filtering device is used to filter the sewage. The filtering device mainly fixes the small solid particles in the sewage by using a filter membrane when in use. In order to avoid the solid particles from blocking the filter membrane, a vibration platform is used to generate a tangential force on the filter membrane by vibrating thousands of times per minute. During the filtering process, the tangential force is generated on the surface of the filter membrane while maintaining the original positive pressure of the filter membrane, so as to increase the filtering amount of the filtered liquid in the material liquid to be filtered, prevent the intercepted pollutants from being compressed to the surface of the filter membrane, and enable the intercepted pollutants to be vibrated off the filter membrane by the tangential force generated by the vibration platform, thereby reducing the degree of blocking of the filter membrane during the filtering process and increasing the filtering efficiency.

[0003] The existing vibration platform filtering device only uses vibration or flushing to remove impurities on the filter surface of the filter membrane when filtering and treating the sewage. However, compared with solid particles, flocculent impurities in the sewage are more likely to adhere to and block the filter membrane during the filtering process by the filter membrane. Therefore, only treating the filter membrane cannot effectively prevent the filter membrane from being blocked. The existing vibration platform filtering device cannot effectively clean the non-filtering surface of the filter membrane in the reverse direction, so that the filtering device has poor anti-blocking and cleaning effect, which affects the filtering performance of the sewage.

[0004] We can find that the existing vibration platform filtering device cannot avoid the above problems when in use, and even if it can solve the problems, it needs to be solved by external tools, so it cannot achieve the desired effect.

[0027] Specifically, the vibration platform filtration device in working / using: First, the first one-way valve 308 and the second one-way valve 310 are respectively connected with the sewage input pipeline and the clean water output pipeline, then the sewage with a certain pressure enters the inside of the filter cartridge 2 through the first one-way valve 308, then the double-shaft motor 408 and the exciter 414 are connected with an external power supply and a controller, at this time, the vibration generated by the exciter 414 cooperates with the elastic seat 413, the support frame 401 and the base 1, can drive the filter cartridge 2 to vibrate vertically at high frequency, and then drive the filter membrane 304 to vibrate vertically at high frequency through the fixing frame 303, so as to form a tangential shear force and a velocity gradient on the membrane surface of the filter membrane 304, when the filter membrane 304 vibrates, the vibration energy is transmitted to the sewage liquid, high-intensity turbulence is generated, the mass transfer efficiency of the substance is enhanced, the permeation flux is improved, the adhesion of pollutants on the membrane surface is destroyed, the formation of the gel layer is prevented, the clogging of the membrane holes is delayed, the clogging degree of the filter membrane 304 in the filtration process is reduced, and the filtration efficiency is improved; Then, the power provided by the dual-shaft motor 408 matches the stable frame 407, which can drive the transmission rod 410 to rotate through the first bevel gear 409 matching the second bevel gear 411. When the transmission rod 410 rotates, it can drive the positioning rod 406 and the convex block 405 to rotate through the second bevel gear 411 and the third bevel gear 412. At this time, the eccentric circle special shape of the convex block 405 can force the rectangular frame 402 to move up and down by matching the roller shaft 403. At this time, the support frame 401 limits the rectangular frame 402, so that the rectangular frame 402 can drive the movable rod 301 to move up and down, ensuring the smooth movement of the piston plate 302. When the movable rod 301 drives the piston plate 302 to move downward, the piston plate 302 can extrude the sewage as it moves downward to approach the fixed frame 303, so that the sewage can be filtered faster through the filter membrane 304. The filter membrane 304 at the top does not change its position, so as the piston plate 302 at the top moves downward, a negative pressure is formed below the filter membrane 304 at the top to generate suction, and the rubber membrane 322 is concave inward, so that the sewage at the top of the filter cylinder 2 can also be filtered faster by the filter membrane 304 at the top through the negative pressure suction. When the piston plate 302 moves downward, the first one-way valve 308 is open and the second one-way valve 310 is closed. Finally, when the movable rod 301 drives the piston plate 302 to move upward, the first one-way valve 308 is closed to prevent backflow of sewage, and the second one-way valve 310 is open to ensure that the filtered water can be discharged outward through the drain pipe 309. Because the drain speed of the drain pipe 309 is limited and the piston plate 302 moves upward at a relatively fast speed, part of the filtered water and gas will be pushed by the piston plate 302, impacting the filter membrane 304 from bottom to top, so that the lint and solid particles and other impurities attached to the filter membrane 304 are quickly washed away and gradually diffuse to the inside of the collection cover 305, realizing efficient cleaning of the filter membrane 304. The filter membrane 304 can filter sewage in a breathing manner, inhale to filter sewage and exhale to complete the cleaning of the filter membrane 304 to prevent blockage, so that the vibration platform filter device can clean the blocked impurities on the filter membrane 304 more quickly and effectively. When it is necessary to clean the impurities in the collection cover 305, the control valve 319 can be opened. The filter membrane 304 at the top can also achieve backflushing cleaning by the protruding deformation of the rubber membrane 322, and the rubber ring 313 can be tightly pressed on the fixed frame 303 by the elastic force provided by the positioning frame 311 matching the tightening spring 312, thereby sealing the gap between the fixed frame 303 and the piston plate 302 to prevent sewage from leaking and contaminating the filtered water.
