4results about How to "Achieve filtering effect" patented technology

This invention relates to the field of water treatment technology and discloses a water softening device based on induced crystallization, including a tank. A filtration and cleaning mechanism for filtering and cleaning crystals is located at the rear end of the tank, and a stirring and cleaning mechanism for cleaning the inner wall of the tank and conveying crystals is located at the front end of the tank. The crystal conveying direction of the stirring and cleaning mechanism is coaxially aligned with the crystal filtration inlet of the filtration and cleaning mechanism, and the stirring speed of the stirring and cleaning mechanism is adapted to the filtration rotation speed of the filtration and cleaning mechanism, achieving continuous crystal conveying and integrated filtration. A flexible reciprocating scraper is installed inside the filter screen to achieve online descaling without stopping the machine, solving the problem of low automation in existing equipment for crystal discharge. A 1:2 meshing ratio between the semi-trapezoidal gear and the trapezoidal gear enables low-speed uniform rotation of the filter tank, preventing crystal seed loss with the filtrate and solving the problem of crystal seed loss in existing equipment.

This utility model relates to the field of disinfectant filtration and recovery technology, and in particular to a novel disinfectant filtration and recovery device, comprising a box and vertical blocks. Vertical blocks are fixedly connected to both sides of the lower end of the box. The box contains a disinfectant filtration structure. The inner walls of the box and the box cover are threaded with bolts. Disinfectant recovery structures are located on both sides of the box. The inner wall of the cylinder is in contact with the filter cloth, and the upper side of the filter cloth abuts against a protrusion. A rope is wound around the outer wall of the filter cloth. Through the cooperation of the disinfectant filtration structure and the box, the output shaft of the servo motor rotates, driving the cylinder to rotate. The rotation of the cylinder causes the disinfectant inside to flow through the filter cloth and the outlet into the box. Utilizing the centrifugal force generated by the rotation of the cylinder, a large amount of disinfectant can be thrown through the filter cloth and the outlet in a short time, while impurities are retained within the filter cloth, achieving solid-liquid separation and thus achieving the filtration effect and improving filtration efficiency.

The utility model relates to the field of fumigating devices, in particular to a three-dimensional circulation fumigating device for a granary, which comprises a fumigating device body, the fumigating device body comprises a fumigating machine, one side of the fumigating machine is fixedly communicated with a fumigating box, and an inner cavity of the fumigating box is fixedly connected with a placing tank. According to the device, gas in the fumigation box is absorbed through the work of the fan, the output pipe conveys the gas into the fan, then the fan conveys the gas into the filter box, the gas is effectively filtered by the first filter screen and then discharged to the outside, and the filtering effect is achieved; the problems that after the fumigation device finishes working, fumigation gas is contained in the fumigation box, gas components are complex, a large amount of harmful substances such as formaldehyde and ethylene oxide are contained, the gas can seriously pollute air and destroy the surrounding ecological environment, pungent peculiar smells can be emitted, and the environment of a working area is affected are solved.

The utility model provides a novel shrinkage film blowing machine for shrinkage film blowing processing relates to film blowing machine technical field, the utility model discloses the work table is placed on the ground to the whole provides the support, the upper surface fixed connection of work table has extruder, wherein the inside of extruder is provided with heating assembly, the upper surface fixed connection of extruder has the feed frame, one end fixed connection of extruder has the mould, the herringbone roll is installed on the upper surface of work table by the aid of support, wherein the herringbone roll is located the just above mould, the winding shaft is installed on one side of work table, wherein the winding shaft can be rolled to the shrinkage film, the utility model discloses the filter screen of vibration device setting reached the effect of the filtration to metal particle, avoid metal particle to enter the inside of extruder, the condition of film blowing machine damage happens, avoids metal particle to block the filter screen simultaneously, improved the practicality of filter screen.
