Description
Technical Field
The present invention relates to the field of clarification filters.
Background
The multi-medium filter is prepared by passing water with high turbidity under a certain pressure through one or more filter media
Granular or non-granular material of a certain thickness, thereby effectively removing suspended impurities and clarifying water, and the common filtering material is stone
The water treatment device is mainly used for water treatment and turbidity removal, softening of water, pre-treatment of pure water and the like, the existing multi-medium filter generally adopts top water inflow, and inflow water is filtered and discharged through a filter material layer by gravity sedimentation, but impurities such as sludge can be gradually accumulated on the surface of the filter material in the long-term use process, the filtering effect is greatly reduced, a large amount of water is required for back flushing, the water source waste is serious, the energy consumption is greatly increased, the service life of the filter material is short, and the filter material needs to be improved.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the multi-medium filter which can automatically perform back flushing, does not need an external water source for flushing, and greatly prolongs the service life of the filter material.
In order to achieve the purpose of the invention, the following technical scheme is provided: the utility model provides a multi-media filter, includes square jar body, and its characterized in that is provided with the toper baffle in the jar body and divide into two upper and lower cavities with the jar body, and the upper cavity is the fresh water tank, and the lower cavity is the filtration storehouse, has seted up the outlet pipe on filtration storehouse top, be provided with the filtration packing layer below the toper baffle in the filtration storehouse, the interval space between filtration packing layer and the toper baffle constitutes flocculation turbulence passageway, flocculation turbulence passageway center is provided with rotatory impeller, is provided with the inlet tube on the left end jar body of flocculation turbulence passageway, and the inlet tube flushes with the filtration packing layer, and flocculation turbulence passageway right-hand member jar is external to be provided with the sludge collecting hopper, and the nearly top of sludge collecting hopper advances the mud mouth and flushes with the filtration packing layer, makes inlet tube, flocculation turbulence passageway, the passageway that advances mud mouth and forms the runner that the bottom surface level link up, and the fresh water tank is provided with backwash/wet return and connects the outlet pipe, is provided with two-way stop valve on the backwash/wet return.
Preferably, the upper end face of the mud inlet is provided with a guide plate which is inclined downwards.
Preferably, the filter packing layer comprises a smokeless coal layer, a quartz sand layer and a pebble layer from top to bottom, wherein the particle size of particles in the smokeless coal layer and the pebble layer is larger than that in the quartz sand layer.
The invention has the technical key that the surface of the filter material is flushed while water is fed, the rotary impeller is impacted by the flow of the water, the rotary impeller is given rotary power, sludge such as sludge in sewage is continuously mixed and stirred, the sludge cannot be accumulated on the surface of the filter material, the sludge can be prevented from depositing by the design of the outside sludge collecting hopper, the concentration of the sludge is controlled, and the water is limited in a flocculation turbulence channel due to the arrangement of the conical partition plate, so that downward pressure is generated in the channel, and the water filtering efficiency is accelerated.
The invention has the beneficial effects that: the invention greatly improves the filtering efficiency and the service life of the filter material, does not need external water source for back flushing, and greatly saves water source and energy consumption.
