The invention discloses a filter screen immersion water washing type papermaking filter device. A recovery inlet is formed in the left side wall of a recovery tank; a filtering bracket which is obliquely arranged downwards from left to right is fixed at the upper end of the right end surface of a left vertical plate; the right end of the filtering bracket penetrates through the recovery inlet; a filtering tank is formed in the upper end surface of the filtering bracket; a filter screen placement groove penetrating front and back is formed in the lower end surface of the filtering bracket; theright part of the filter screen placement groove is communicated with the filter tank; a water falling groove is formed in the upper end face of a supporting platform. The water falling groove is a cuboid with a rectangular-groove-shaped water storage tank formed in the upper end face. A filter screen cleaning device comprises a pair of U-shaped filter screen supporting seats which are arranged inthe water storage tank in a synchronous lifting manner and are symmetrically arranged front and back; and a filter screen is rotationally arranged between the upper ends of the vertical parts on theright sides of the pair of filter screen supporting seats.
Description
Technical field [0001] The invention relates to the field of papermaking machinery, in particular to a papermaking filter device with a filter net immersed in water and washing. Background technique [0002] The papermaking machinery pulp filter device is a device used to filter out the moisture in the pulp, which can control the concentration of the pulp. It is a very important step in the papermaking process. The filtering effect will eventually seriously affect the quality of the paper. At present, the most common method used in papermaking machinery pulp filtration devices is the oblique vertical screen frame recovery method. The reason why this method is popular is that this method does not need to provide additional power. The papermaking machinery pulp is moved from the filter to the filter screen under the action of gravity. The effect of filtering part of the moisture can be achieved in the process of downward flow; the existing papermaking machinery pulping filter devic...
