6results about How to "Reduce filtration efficiency" patented technology

The application discloses a kind of intelligent filter-pressing devices and processes suitable for organic silicon of filter-pressing device technical field, including support seat, the front and rear ends of the support seat are all fixedly connected with main beam, and the side away from support seat between two main beams is fixedly connected with thrust plate;After the end of filter-pressing, external controller will control drive block to open filter plate one by one, filter cake falls off, during the movement of filter plate, filter cloth will be separated from filter plate under the action of separation plate, which is conducive to the separation of filter cloth and filter plate, the filter residue attached to the surface of filter cloth can be separated from filter plate, which is convenient for subsequent cleaning, to avoid filter cloth and filter plate sticking together during cleaning, filter residue will be closely attached to the surface of filter cloth and filter plate during filter-pressing, which makes it difficult to clean;Subsequently, the filter residue on the surface of filter cloth will be scraped off by scraping block, which is conducive to cleaning the filter residue remaining on the surface of filter cloth after one filter-pressing, to avoid the influence of residual filter residue on the filtering effect of filter cloth.

This invention discloses a silicon wafer cutting fluid filtration device, specifically comprising: a base, a purification device movably connected to the top right side of the base, a housing fixedly installed on the top side of the base away from the purification device, and the housing and the purification device being opposite to each other; a partition plate fixedly connected to the top of the housing; a movable rod accessory on the side of the purification device near the center of the partition plate; and a dispensing device rotatably installed in the center of the partition plate via the movable rod accessory. This invention relates to the field of filtration technology. This silicon wafer cutting fluid filtration device uses the bottom left side of the central support frame as a support point. The wheel rim vibrates, and the vibration on the wheel rim gradually moves in conjunction with the ring plate. The upper surface of the ring plate gradually vibrates accordingly, and the vibration of the ring plate gradually adjusts the position of the top silicon wafer workpiece, reducing the accumulation of silicon wafers in one place, thus reducing the reduction in filtration efficiency and the accumulation of cutting fluid in one place, further improving the silicon wafer filtration effect.

This invention discloses a production process for filter screen manufacturing equipment and the resulting filter screen. The aim is to provide a high-efficiency, precise, and automated production process for filter screen manufacturing equipment and the resulting filter screen. The key technical points include a combination of numerous process flows such as raw material preparation, cutting and shaping, screen frame forming and fabrication, secondary shaping of the screen frame, and assembly. Precise control at each stage significantly improves product quality, production efficiency, and market competitiveness, resulting in good economic and social benefits. This invention applies to the field of filter screen manufacturing equipment technology.

This invention relates to the field of fly ash concrete filtration technology, and provides a fly ash slag concrete filtration device, including a housing and a filter screen slidably disposed within the housing for filtering fly ash slag; a first guide rod fixedly installed within the housing, on which a first guide plate is slidably sleeved; an exhaust pipe fixedly installed on the first guide plate for flushing the filter screen with high-pressure gas, the exhaust pipe being located below the filter screen; and a scraper disposed within the housing for cleaning slag from the filter screen. The fly ash slag concrete filtration device provided by this solution facilitates the rapid and effective removal of fly ash slag from the fly ash slag filter screen, while also effectively reducing the probability of filter screen clogging, ensuring filtration effect and speed, reducing labor intensity, lowering operational difficulty, and improving work safety.

This utility model discloses a multi-layer ventilation filter for the aquaculture industry, relating to the technical field of air filtration equipment. The utility model includes a mounting frame with several mounting holes on its inner wall. A dustproof plate is slidably connected to the top outer wall of the mounting frame. An adjustment mechanism is provided on the outer wall of the mounting frame, including a rotating shaft. The outer wall of the rotating shaft is rotatably connected to the outer wall of the mounting frame, and a gear disk is rotatably connected to the outer wall of the rotating shaft. By providing mounting holes, this utility model allows the mounting frame to be quickly installed on a wall or external device when needed. The air filter membrane is then fitted onto a support tube, and the support tube is inserted into a limiting block and rotated at a certain angle. This facilitates the user in fixing the air filter membrane to the device and allows for adjustment of the air filter membrane, ensuring it remains taut.

This invention discloses an automatic backwashing filtration device with a dual centrifugal and dual-net structure, including a water storage cylinder with a second connecting pipe fixedly connected to it. This invention employs an innovative architecture of centrifugal sedimentation + dual-net graded filtration: high-speed rotation inside the filter cylinder generates centrifugal force to separate large particles such as silt and organic matter from the water; the double-layer stainless steel filter inside the filter cylinder precisely intercepts suspended solids, adapting to different water qualities; the operation of the first and second cylinders respectively drives the movement of the first and second support columns, thereby adjusting the height of the water storage cylinder and providing flexibility for different installation scenarios; the first sliding plate slides into the groove of the second sliding plate, and the first connecting plate and the enclosed cavity form a closed space, preventing the second solenoid valve from being affected by environmental dust, moisture, or electromagnetic interference, avoiding abnormal control signals, and improving the stability and reliability of the equipment operation.
