  • the present invention belongs to the technical field of filtering apparatus.
  • Automatic laminated filters which are widely used in developed countries, generally comprises a filter housing and a filter core, wherein the filter core is a hollow cylinder which consists of a multitude of annular discs having grooves at two sides and assembled on a central frame.
  • the annular discs are pressed by springs at two ends of the central frame and also by the water pressure so as to form a filtering body, and fluid flows through a gap formed between every two discs. Since a filtering surface is formed within the gap between every two discs, the filtered flow rate of a single filter disc is small. Once a filter is assembled, its filtering capacity is fixed and is small because of the small filtering surface. Furthermore, because the size of the gaps between the discs after being pressed is fixed, the filtering effect is fixed and cannot meet different filtering requirements.
  • the above prior art laminated filter is generally cleaned by backwashing.
  • a backwashing process the direction of the water flow in a filter unit is varied by means of a backwash valve, the springs pressed on the filter core is pushed away by water pressure and all the small gaps between the discs are expanded, and a tube located at the center of the filter core injects water along a tangent direction to rotate the discs. Accordingly, with the washing of the water and centrifugal force generated by high speed rotation of the discs, substances remained on the discs are flushed out. After the backwashing process, the discs are re-pressed and recovered to a filtering state by means of the springs on the filter core.
  • the filtering effect of this filter is good, but it is difficult for the backwashing water to clean off the filth adhering to the discs, thus the filtering effect will certainly be affected as time goes by. Because the filter is used in a filtering system of large water flow rate, cleaning problem is particularly significant. It can only be thoroughly cleaned by manual washing, which requires a great amount of labor force and high cost, and also the machine has to be stopped during cleaning, such that the system cannot operate continuously.

  • An outer periphery of the annular frame is provided with filtering pores or is sealed against water.
  • An internal ring of the annular frame projects beyond the annular surfaces thereof to form a projecting shoulder.
  • the outer periphery of the annular disc pieces is circular.

  • the cleaning device in order to better clean off the filth on the disc surfaces, further comprises a high pressure flushing device 4.
  • the high pressure flushing device 4 comprises a high pressure pump 401, a water inlet pipe 402 of the high pressure pump 401, an outflow water transporting pipe 403 of the high pressure pump 401, a number of water transporting branching pipes 404 and a number of injection tubes 405.
  • the outflow water transporting pipe 403 is connected to a water outlet of the high pressure pump 401, and the other end is secured to the installation frame 304 and is herein divided into a number of water transporting branching pipes 404, with the other end of the water transporting branching pipes 404 being secured to the stop plate 305.
  • the water transporting branching pipes 404 are located at the outside of the hollow filter discs 201 and each of the water transporting branching pipes 404 is provided with a number of injection tubes 405, which extend into the disc surfaces of the hollow filter discs 201 and are provided with a number of injection openings from which water is injected at an angle onto the disc surfaces of the annular disc pieces 2011.
  • the hollow filter disc and the filter comprising the same can find a wide application in filtering of vessel ballast water, heat exchanger water, circulating cooling water, nozzle water, pre-treated water for super filtering and micro filtering, water softening system, waste water, recycle water, and water used in food, medicine, vehicle, electronics, metallurgy, chemistry, culture, agricultural irrigation industries and etc.

Abstract

La présente invention concerne un disque à filtre creux (201) et un filtre stratifié comprenant celui-ci. Le disque à filtre creux (201) comprend deux pièces de disque annulaires (2011) avec des pores filtrant et un cadre annulaire creux en interne (2012) dimensionné et formé de manière à correspondre aux pièces de disque annulaires (2011), une pluralité de trous de passage (2014) étant disposés à la périphérie interne du cadre annulaire (2012), et chacune des pièces de disque annulaire (2011) est pressée et fixée de façon détachable à l'une correspondante des surfaces annulaires du cadre annulaire (2012) et est scellée contre celle-ci aux jonctions entre celles-ci, de manière à former une chambre de réservoir d'eau entre les deux pièces de disque annulaire (2011) et le cadre annulaire (2012). Le filtre stratifié a un noyau de filtre composé d'un groupe desdits filtres à disque creux (201) et un tuyau central d'écoulement d'eau (202) pourvu d'une pluralité d'oxygènes d'entrée d'eau (2021) à sa périphérie, les filtres à disque creux (201) étant insérés par le tuyau central d'écoulement d'eau (202). Le filtre stratifié peut être pourvu d'un dispositif de nettoyage automatique ou d'un dispositif de nettoyage automatique non motorisé.
