Description
Technical field
The utility model relates to a kind of filter, particularly relates to a kind of pressure disc type filter, is the filter plant that is applied in the paper technology in paper mill.
Background technology
At present, the alkali in paper mill reclaims the washing of caustic room white clay and green mud with concentrated, mainly is to use filter.Filter commonly used generally is to adopt single screen pack as filter medium, and this filter plant is simple in structure, but filter effect is relatively poor.Along with the continuous development of filtering technique, pre-hanging filter has appearred, and pre-hanging filter and former filter compare, and maximum characteristics have adopted the pre-hung technology exactly.The pre-hung The Application of Technology makes filter medium become screen pack and white clay pre-hung layer by single screen pack.Because the pre-hung layer is to be made of the white clay particle, the granularity of white clay thereby constitutes countless micropores and finishes the work of filter medium jointly with the rarer filter screen of mesh about 40-50 μ m, under the high vacuum effect, can obtain filter effect preferably.But exist equipment big, the shortcoming that filtering surface is little.
The utility model content
In order to solve the defective that above-mentioned filter exists, the utility model provides that a kind of filter area is big, good filtration effect, filter compact conformation, that operate under positive pressure.
The technical solution of the utility model is: a kind of filter, comprise hollow shaft, be fixed in the filter on the hollow shaft, the doctor blade device that is used for discharging and tank body, it is characterized in that: described filter is the axial arranged circular filtering table along hollow shaft of at least one, and this circle filtering table is made up of a plurality of cavitys of arranging along disc; Tank body is by cylindrical shell and two sealing load tank bodies that end socket is formed; In hollow shaft, be provided with the hollow cylinder concentric with hollow shaft, described hollow shaft inwall and cylinder outer wall constitute ring cavity, at setting between the interior lateral wall of ring cavity and the corresponding vertical cavity independent of each other of the cavity on the filter disc, each vertical cavity communicates with corresponding cavity on each filtering table.
The cavity of described filtering table is furnished with the fanning strip of aperture and the fan-shaped cavity of the top seal that two dividing plates are formed by two surfaces, and the fan-shaped cavity bottom is provided with liquid collecting funnel and corresponding vertical cavity connection.
The utility model also comprises the swingable spray cleaning device of being located on the tank body upper inside wall, wave the spray cleaning device by linkage and spray wash the pipe form, spray is washed pipe and is formed at least one group of nozzle of every arm lower end symmetric arrangement by a water spray house steward with along water spray house steward length direction layout and the inner with it at least one arm that communicates.Wave the spray cleaning device and realize swing by linkage.Scraper in the described doctor blade device is movably and automatic adjusting play, and it comprises a gap adjusting mechanism.
The utility model is applicable to the pre-hung technology, and filter medium is filter screen and white clay pre-hung layer when promptly moving.The operation of this filter is to finish filtration under the externally compressed-air actuated effect.The pressure air that Air pressurizer produces is squeezed in the tank body, the emulsion in the tank body under pressure, white clay is adsorbed on the fanning strip surface of filter disc as the pre-hung layer.During filtration, the filter course of filtrate by being made up of white clay and filter screen enters fan-shaped cavity, and the liquid collecting funnel through the fan-shaped cavity bottom flows in the vertical cavity that communicates with it, discharges tank body by this cavity again.
The utility model also is provided with and waves the spray cleaning device, by the water under high pressure that is contained in the nozzle ejection 0.7～0.9MPa on the sparge pipe that can swing filter screen is washed, and bur on the filtering net surface is rinsed out the cleaning filter screen.The swing of water spray arm is realized by linkage by cycloidal planetary gear speed reducer.
What scraper discharging of the present utility model adopted is the automatic scraper discharge way, and scraper is finished feed, tool backlash movement automatically according to the liquid level in the tank body.
Beneficial effect:
The utility model is compared with the filter of single screen pack, owing to be applicable to the pre-hung technology, filter medium becomes filter screen by single filter screen and white clay pre-hung layer combines, and gained filtrate has very high clarity.
The utility model is compared with existing pre-hanging filter, owing to adopted the technology of a plurality of filtering tables, makes filter area by single bulging face, changes multi-level card into, has increased effective filtration area.Under the condition of equal filter area, body is littler than pre-hanging filter.Both increased production capacity, and made device structure compact more again.
In addition, the utility model is because be to operate under positive pressure, and tank body is a pressure vessel, and all externally all have high sealing, does not have and leaks, the working environment cleaning.Everything all is electrical control, the automaticity height.
