Preferably, screen pack adopts PP plate to make, and filter bores is striated hole, and the length in every striated hole is 5mm, and aperture is 1mm, is 45 ° with the edge of PP plate.
Preferably, screen pack is one deck, two layers or multilayer, and on each layer, a part for filter bores is aimed at.
Preferably, the gradient 15 ~ 25 ° of the sloping portion of screen pack.
Preferably, at the medial surface of casing, be provided with the supporting plate with the same material of welding box body, screen pack is fixed on supporting plate by peripheral sealing pad.
Preferably, the terrace part of filter screen and sloping portion are that a spares bend forms, or are welded with homogeneous material.
Preferably, the terrace part of filter screen is also provided with filter bores.
Preferably, Rose Box is hexahedron structure, or inversed taper platform structure.
According to another aspect of the present invention, provide a kind of solution filtration processes, it is characterized in that, the solution filtering device adopted is the Rose Box comprising band removable cover, inner being divided into by screen pack of this Rose Box is filtered upper space and is filtered lower space, in filtration, space communicates with the charging aperture of Rose Box side, and space communicates with the discharging opening of filter box bottom surface under filtering, screen pack comprises the terrace part for depositing impurity and plays the sloping portion of solid-liquor separation effect, the sloping portion of screen pack is provided with a series of filter bores, filter bores is elongated shape at least partially, longitudinal line of symmetry of this filter bores is acute angle relative to the intersecting lens being provided with the side of charging hole of screen pack and Rose Box,
Solution enters space in the filtration of Rose Box through charging aperture, and impurity is upwards piled up because of the pressure washing of feedstock solution, is flushed to platform, filter lower space by arriving after filter screen filtration simultaneously, flowed out by discharging opening, impurity is then deposited on the terrace part of screen pack again, concentrates afterwards and removes.
Preferably, screen pack adopts PP plate to make, and filter bores is striated hole, and the length in every striated hole is 5mm, and aperture is 1mm, is 45 ° with the edge of PP plate, the gradient of the sloping portion of screen pack 15 ~ 25 °.
According to filter of the present invention, screen cloth is striated hole, and structure is simple, good filtration effect, be not easy blocking.
Adopt according to after filter of the present invention, compared with directly entering spray drying device with traditional solution, after using filter purified solution of the present invention, follow-up producing process can be avoided to be entrained into mechanical admixture, improve the quality of products.
Accompanying drawing explanation
Fig. 1 is the structural representation according to filter of the present invention.
Detailed description of the invention
As shown in Figure 1, according to filter of the present invention, it is a kind of structure of Rose Box 100.Concrete technical scheme is, one is had to be the rectangular box of removable cover 101 above, a side of casing has charging aperture 102, there is below casing a discharging opening 103, box house is provided with the filter screen 10 of certain slope, play solid-liquor separation effect, the top of filter screen 10 connects a platform 20, for depositing impurity.
Its operation principle is, solution enters Rose Box 100 through charging aperture 102, and flow out 103 by discharging opening after being filtered by filter screen 10, impurity is then deposited on the platform 20 of filter screen, impurity is upwards piled up because of the pressure washing of feedstock solution, and after being flushed to platform 20, row is removed again.
In one embodiment, filter screen 10 adopts PP plate to make, and is provided with striated hole 30, and the length in every striated hole 30 is 5mm, and aperture is 1mm, angled with the edge in plate face (such as 45 °).Filter screen is one deck, as needs, can be designed to multilayer.As screen cloth impurity is too much, removable cover 101 can be opened and clear up.
The gradient of filter screen 15 ~ 25 °, is greater than 25 ° and is not easy to liquid impurity is rushed to platform 20.Be less than 15 °, flow rate of liquid is fast, and to platform 20 in major part, cause liquid to flow backwards, impurity is refunded on swash plate 10 with liquid.
According to gradient and the height of filter screen, at medial surface welding and the supporting plate of casing with material of casing, the tapping of supporting plate upper drill hole, is fixed on the filter screen plastic bolt of band seal perimeter on supporting plate.
Platform 20 part of filter screen is one with there being the part 10 of certain slope, or welds with homogeneous material.
