Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
The winterization filter that the utility model provides comprises filter plate and the filter cloth that some pieces have hollow sheeting chamber, described some pieces of filter plates are closely stacked successively, every block filter plate all offers oil strain through hole, and the oil strain through hole on adjacent filter plate interconnects thus forms oil strain pipeline; The outer surface of described filter plate comprises filtering surface and is positioned at the stationary plane of filtering surface periphery, the bottom of the filtering surface of every block filter plate is provided with lower fuel feed hole, top is provided with fuel feed hole, the bottom of the stationary plane of every block filter plate is provided with lower oil outlet, top is provided with oil outlet, described lower fuel feed hole, upper oil outlet, lower oil outlet and upper oil outlet are all communicated with the hollow sheeting chamber of this block filter plate, lower oil outlet on adjacent filter plate, upper oil outlet interconnect respectively thus form lower flowline and upper flowline, and one end of described upper flowline is sealed; The outer surface of described every block filter plate and oil strain through hole all overlap and have filter cloth, there is space between described filter cloth and described filter plate, for circulating the edible vegetable oil after filtering.
See Fig. 1, it is the overall structure schematic diagram of the utility model winterization filter.As an embodiment of the present utility model, described winterization filter comprises the filter plate 1 that some pieces have hollow sheeting chamber, described some pieces of filter plates 1 are closely stacked successively, and every block filter plate 1 all offers oil strain through hole 2, and the oil strain through hole 2 on adjacent filter plate 1 interconnects thus forms oil strain pipeline.
It should be noted that, should closely compress between adjacent filter plate 1, Fig. 1 gives arrangement mode and the structure of filter plate, and for convenience of understanding, each piece of filter plate 1 is decomposed out.Preferably, the centre of every block filter plate 1 offers oil strain through hole 2, to ensure the connectivity of oil strain pipeline.Oil (i.e. slip) to be filtered after crystallization enters described winterization filter by oil strain pipeline.
The outer surface of described every block filter plate 1 and oil strain through hole 2 all overlap filter cloth, there is space between described filter cloth and described filter plate 1, for flowing through the edible vegetable oil after filter-cloth filtering.
Fig. 2 is the filter-plate structure schematic diagram of the utility model winterization filter, the outer surface of described filter plate 1 comprises filtering surface 12 and is positioned at the stationary plane 11 of filtering surface 12 periphery, the bottom of the filtering surface 12 of every block filter plate is provided with lower fuel feed hole 5, top is provided with fuel feed hole 8, the bottom of the stationary plane 11 of every block filter plate is provided with lower oil outlet 3, top is provided with oil outlet 4, described lower fuel feed hole 5, upper oil outlet 8, lower oil outlet 3 is all communicated with the hollow sheeting chamber of this block filter plate 1 with upper oil outlet 4, lower oil outlet 3 on adjacent filter plate, upper oil outlet 4 interconnects respectively thus forms lower flowline 30 and upper flowline 40.Described filtering surface 12 is that irregular plane (can realize by arranging protruding mode on the surface of filtering surface 12, also can be realized by some other usual manner), when it and filter cloth is fitted time can there is space, edible vegetable oil just flows in this space.Therefore, the edible vegetable oil flowed in space can enter hollow sheeting chamber respectively by lower fuel feed hole 5 and upper fuel feed hole 8, flow out hollow sheeting chamber by lower oil outlet 3 and upper oil outlet 4 again, then flow out described winterization filter by lower flowline 30 and upper flowline 40.
Further, one end of described upper flowline 40 is sealed.Sealing end can be positioned at same one end of slurry inlet, also can be positioned at the other end of slurry inlet.In this enforcement, the upper oil outlet 4 in the one side that first piece of filter plate 1 is not fitted with other filter plates is sealed, thus forces the edible vegetable oil entering flowline 40 to flow to a direction.In other embodiments, the upper oil outlet 4 in the one side also last block filter plate 1 can not fitted with other filter plates is sealed.Preferably, one end of described lower flowline 30 is sealed.Alternatively, the lower oil outlet 3 in described end filter plate 1 one side of not fitting with other filter plates is sealed.
Further, described lower flowline 30 is provided with lower draining valve 7, described upper flowline 40 is provided with draining valve 6.
During oil strain, first lower draining valve 7 is closed, treat that oil strain (slip namely in Fig. 1) enters oil strain pipeline from oil strain hole 2, flow between each filter plate 1, because this winterization filter is in pressurized state and the gravity acting of oil itself, treat that oil strain can filter the filter cloth wrapped on filter plate 1 and enter space between filter cloth and filter plate 1, and based on connection principle, the edible vegetable oil after filtration can enter in the hollow sheeting chamber of filter plate 1 via the lower fuel feed hole 5 of bottom, filter plates face 12.Because lower draining valve 7 cuts out, edible vegetable oil can rise in hollow sheeting chamber inner accumulated, rises and pressure along with pasta, and oil to be filtered can enter space from the first half of filter plate 1 through filter cloth, and filter cake is evenly distributed on filter cloth.The edible vegetable oil in hollow sheeting chamber amasss completely and enters upper flowline 40 from upper oil outlet 4 outflow.Because one end of upper flowline is sealed, therefore edible vegetable oil can flow to downstream along upper flowline 40, enters edible vegetable oil temporary storage tank (not shown).When on go out oil pressure reach certain value time, the pressure that the present embodiment is determined is 0.4MPA, is opened by lower draining valve 7, simultaneously fuel-displaced up and down, finally makes the upper and lower thickness of cake layer even, and the edible vegetable oil in upper flowline and lower flowline all enters edible vegetable oil temporary storage tank.
As an embodiment of the present utility model, the both sides on stationary plane 11 top of described every block filter plate 1 are respectively equipped with a upper oil outlet 4, thus form two upper flowlines 40; The both sides of stationary plane 11 bottom of described every block filter plate 1 are respectively equipped with a lower oil outlet 3, thus form two lower flowlines 30.
Preferably, described hollow sheeting chamber and upper oil outlet 4 are by upper plate chamber pipeline communication, and the angle of the perpendicular bisector of described upper plate lumen road and upper oil outlet 4 is 30 ~ 60 °; Described hollow sheeting chamber and lower oil outlet 3 are by lower plate chamber pipeline communication, and the angle of the perpendicular bisector of described lower plate lumen road and lower oil outlet 3 is 30 ~ 60 °.In the present embodiment, described hollow sheeting chamber and upper oil outlet 4 are by upper plate chamber pipeline communication, and the angle of the perpendicular bisector of described upper plate lumen road and upper oil outlet 4 is 40 ~ 50 °; Described hollow sheeting chamber and lower oil outlet 3 are by lower plate chamber pipeline communication, and the angle of the perpendicular bisector of described lower plate lumen road and lower oil outlet 3 is 40 ~ 50 °.
More preferably, the aperture of described upper fuel feed hole is 1:10 ~ 1:30 with the ratio in the aperture of upper oil outlet 4; The aperture of described lower fuel feed hole is 1:10 ~ 1:30 with the ratio in the aperture of lower oil outlet 3.In the present embodiment, the aperture of described upper fuel feed hole is 1:20 with the ratio in the aperture of upper oil outlet 4; The aperture of described lower fuel feed hole is 1:20 with the ratio in the aperture of lower oil outlet 3.
