Abstract
The utility model provides a septum of a rotary squeeze filter and relates to a plate shape device [8] which is arranged on an opening of a C-shaped external septum [2] and separates a ring filtering channel; the upper wall of the septum is positioned from the external to the internal and gradually upward in the range of the ring filtering channel. The septum of the rotary squeeze filter provided by the utility model is characterized in that the upper wall of the septum of a lower side wall which is the feeding inlet of the filter is arranged from the internal to the external and gradually upward in the range of the ring filtering channel, which means that the lower wall of the initial end of the filtering channel in the feeding inlet of the filter gradually goes upward along the flow direction of materials; even if the materials do not produce eddy currents in the feeding inlet, the solids in the materials does not stack because the filtering channel does not produce dead angles. The septum eliminates the phenomenon that in the prior art, the filtering efficiency is influenced as the solids are accumulated and solid materials are coated just before the filtering screen enters the feeding inlet for regeneration.
Description
Technical field
The utility model relates to a kind of dividing plate of rotary extrusion type filter, belong to the solid-liquid separating equipment technical field.
Background technology
The rotary extrusion type filter that uses mainly is made up of Shell Plate, exterior wall plate, main shaft, interior spaced wheel, screen support wheel, filter screen, dividing plate, flashboard etc. at present.Wherein surrounded annular space as filtration channel by filter screen, interior spaced wheel and the fixed exterior wall plate of rotating with main shaft, exterior wall plate be C shape and dividing plate just is mounted in the opening part of C shape exterior wall plate, and its inwall and interior interval crop rotation matched in clearance be used for intercepting the parts that filtration channel forms C shape passage.Lower wall constitutes material inlet and filtered solid outlet on the last lower wall of dividing plate and the exterior wall plate opening, is equipped with filter cake is applied the flashboard of resistance with control filter cake liquid content on filtered solid outlet.Mud or similarly have the solidliquid mixture of small solid particle to enter filtration channel by material inlet is thickened by rare in filtration channel, becomes dry again, and last solid phase is discharged by the filtered solid outlet of flashboard control, and liquid phase is discharged by filtrate (liquid by filter screen.Its dividing plate upper wall of Tong Hang rotary extrusion type filter all was in level is connected on the spaced wheel in the past, therefore the charging aperture bottom that forms be level and with interior spaced wheel junction be a dead angle.Because the existence at said dead angle is very easily piled up its solid matter part of the handled solidliquid mixture of rotary extrusion type filter at this place.Rotation change to squeeze the formula filter when work on its filter screen the few more filter efficiency of accompanying solid high more, generally can before entering the charging aperture scope, wash regeneration, but the solids of being piled up on the charging aperture makes the filter screen of just having regenerated just adhere to solid, has influenced the filter efficiency of filter.
Summary of the invention
At above-mentioned deficiency, the utility model is exactly that a kind of dividing plate that has changed the rotary extrusion type filter of charging aperture shape will be provided.
The dividing plate of the rotary extrusion type filter that the utility model provides is one to be installed on template device on the C shape exterior wall plate opening, that cut off the annular filter passage, and its upper wall in the scope of annular filter passage makes progress from outside to inside gradually.
The dividing plate of the rotary extrusion type filter that the utility model provides, dividing plate upper wall as the lower wall of filter charging aperture from outer to inner makes progress in the scope of annular filter passage gradually, filtration channel initiating terminal lower wall in the filter charging aperture is made progress gradually according to the Flow of Goods and Materials direction, even material can not produce eddy current at the charging aperture place, filtration channel can not produce the dead angle and cause solid accumulation in the material, eliminated in the prior art and just coated the phenomenon that solids influences filter efficiency because of the accumulated solids thing has just been regenerated filter screen before entering charging aperture.
For making processing simple, the dividing plate upper wall that this can be made progress gradually is designed to skew lines, i.e. the upper wall of dividing plate horizontal linear before this, and entering behind the annular filter channel range is the separation of skew lines upwards up to dividing plate and interior spaced wheel.
Description of drawings
Accompanying drawing is the structural representation of the utility model one embodiment, among the figure: 1-material inlet, 2-exterior wall plate, 3-filter screen scraper plate, 4-filtration channel (filter screen is not described among the figure), 5-seal closure, 6-flashboard, 7-scrapes the mud bar, 8-dividing plate, 9-filter screen rinse water spray orifice, 10-sealing strip.
The specific embodiment
One rotary extrusion type filter, there is C shape exterior wall plate 2 to be installed on the support, have interior spaced wheel to be installed on the main shaft, two rings shape flat screen 4 in two screen support wheel, justify be installed in respectively on two end faces of spaced wheel, filtering surface is the endless belt between interior spaced wheel and the exterior wall plate.Interior spaced wheel, exterior wall plate, filter screen have constituted on two outer faces of annular filter passage 4, two Shell Plates respectively installs a seal closure 5, and filtrate (liquid is arranged at the seal closure bottom.On the exterior wall plate of filtration channel The initial segment, also be close to filter screen filter screen scraper plate 3 has been installed.At exterior wall plate C shape opening part dividing plate 8 is installed, dividing plate upper wall and exterior wall plate constitute charging aperture 1, and dividing plate lower wall and exterior wall plate constitute filtered solid outlet, and flashboard 6 is installed on the filtered solid outlet.Dividing plate inwall and interior spaced wheel cylindrical are made matched in clearance, and the dividing plate outer wall is the casing appearance, and two sidewalls of dividing plate and two end faces of exterior wall plate are flat.The lower wall of said dividing plate is a level, and upper wall also upwards is the skew lines shape for level for outer one section gradually when near-ring shape filtration channel scope.Be provided with filter screen flusher 9 on the dividing plate; Nearly lower edge, two side is provided with scrapes mud bar 7, is brought between dividing plate both sides and the filter screen to avoid a large amount of solids; Nearly upper edge, dividing plate two side is provided with sealing strip 10, enters filtered solid outlet to avoid the liquid phase stream in the charging between dividing plate and filter screen.
When material when charging aperture enters filter, through the effect of dividing plate upper wall oblique line, flow into filtration channel on the flow direction of material, can be in the inner phenomenon that produces eddy current and make deposition of solids because of the dead angle of dividing plate upper wall as the dividing plate of horizontal upper wall.
This example does not limit the version of other parts of the utility model rotary extrusion type filter, and the form of dividing plate upper wall also is not limited to skew lines, and can be curve.
Claims (2)
- The dividing plate of 1 rotary extrusion type filter is one to be installed on the template device of the partition annular filter passage on the C shape exterior wall plate opening, it is characterized in that the upper wall of dividing plate in the scope of annular filter passage makes progress from outside to inside gradually.
- The dividing plate of 2 rotary extrusion type filters as claimed in claim 1, the upper wall that it is characterized in that dividing plate is horizontal linear before this, and entering behind the annular filter channel range is skew lines upwards.
