Definitions

  • the present invention relates to a double filter device that allows the removal of impurities from, for example, citrus juices, since this device comprises a first coarse filter and a second fine filter, both self-cleaning.
  • the coarse filter incorporates elements that contribute to the roughing, the removal of coarse elements from the coarse filter and, in turn, the cleaning of the fine filter.
  • Spanish patent ES2071070 refers to a machine that has a filter band comprising a mobile belt made of a flexible and permeable material, supported by a frame that forms a loop around at least two distal rollers of which at least one It is powered by an engine.
  • the utility model ES1045339U comprises a cleaner, scraper or brush, which, together with an endless belt, travels eliminating from a filter the waste (pulp, seeds, etc.) in a squeezing machine.
  • the endless belt is in a rear position, not on the vertical of the filter, and the connection between the endless belt and the brush or sweeper passes through a horizontal groove in the plate that separates the drive group of the squeezing group of a machine with the risk that part of the squeezed juice may enter the mechanisms of the driving group.
  • Patent ES2545235 in its dependent claim 3 shows a sweeper comprising an endless belt arranged on the vertical of the filter to be cleaned.
  • This endless belt has no more function of supporting the scrapers or lips that come in contact with the filter to be cleaned and drag the squeeze remains that may have remained in it.
  • ZUMMO For its part, the Spanish patent ES2609830 refers to an endless belt that is itself a self-cleaning filter, since the remains of squeezed remain on the endless belt itself that filters the liquid and dislodges the remains that fall into a receptacle arranged at the end of the filter stroke.
  • None of the aforementioned background solves the problem of obtaining a juice perfectly without impurities and this is because if a filter of a thick mesh is used, the impurities that can make the juice annoying continue to fall into the juice, and if on the contrary it use a fine mesh filter to obtain a juice free of any impurity, the impurities fill it immediately preventing it from continuing its filtering function so it is necessary to disassemble it to clean it.
  • the present invention relates to a device with which to obtain a juice without impurities in an automatic machine, which does not require constant manual cleaning operations.
  • the invention object of the present invention relates to a self-cleaning filtering device comprising a first coarse or roughing filter and another fine filter where the coarse filter, in turn, supports the elements that clean the fine filter.
  • Both filters, the coarse and the fine, are preferably on the same vertical, the coarse filter being in an upper or upstream position and the fine filter in a lower or downstream position at a sparse and constant distance from each other.
  • the double filter device comprises:
  • a thick filter comprising:
  • a filter band that receives the juice and pulp of the squeeze group, retaining those larger residues.
  • This filter band is an endless band supported on at least two rollers, of which at least one of them is motive.
  • a plurality of lips at least on the outer face of the filter band, which occupy in height the gap between the lower part of the filter band and the fine filter, passing tightly between them.
  • a fine filter disposed downstream of the coarse filter, at a certain distance and consists of the coarse filter, and wherein this fine filter comprises a mesh whose passage hole size is smaller than the size of the coarse filter passage hole.
  • the filter band has holes distributed along its surface. These holes are suitable for retaining the major residues of the squeeze, allowing the juice and some minor debris to fall into the fine filter arranged downstream.
  • this filter band has a series of lips on its outer face so that when these lips travel the upper part of the thick filter participating in the movement of the band, they contribute to drag the waste deposited on this thick filter, and when These lips traverse the lower part of the coarse filter, pass tightly between the filter band and the fine filter, compressing and dragging the debris deposited on the fine filter.
  • the lips are arranged in rows, preferably parallel to each other. Each row comprises lip segments and gaps alternately.
  • the rows are arranged so that each lip of a row corresponds to a gap of the two adjacent rows and each gap of a row corresponds to two lip segments of the respective adjacent rows.
  • the effect of this arrangement is to drag the pulp so that the excess that escapes from each side of a lip segment when being dragged, is picked up by a lip segment of the next row that drags it which, in the case of the filter thick supposes the possibility of a longer residence time on the thick filter allowing a greater obtaining of juice by gravity and movement of the pulp and, in the case of the filter Fine allows moving the pulp and compressing it successively on different lips favoring the efficiency of the squeezing.
  • triangular section any section of the lips that reproduces all or part of the shape of a triangle, either a complete triangle or a trapeze, even when its sides have a slightly convex or concave shape.
  • the lips of the inner face of the filter band engage with longitudinal grooves existing in the support rollers, at least the motors, improving the grip for traction and avoiding slipping.
  • the lips of the inner face are equally segmented and equally arranged than those of the outer face so that the filter band is reversible, which allows its best use since, given a possible wear of the outer lips, You can change position by moving the inner lips to be outer and vice versa.
  • FIG. 1 shows, in explosion, the filtering device (12) comprising a thick filter (1) with a filter band (2) and the rollers (3) that support and move it, a thin filter (4) and a support box (5) with the housings (6) for the rollers and with a lower opening (7) and a cover (8) that closes the assembly and has a recess (9).

  • the assembled filtering device can be seen in FIGURE 3.
  • FIGURE 4 represents a section of the mounted device and this is how the filter band (2), the rollers (3) that support and drag it, the support box (5) and the cover (8) look.
  • the outer lips (10) and inner lips (11) of the filter band are also appreciated.
  • FIGURE 5 shows the filtering device (12) installed in an automatic juice machine under the squeezing group (13) showing at each end of the device, a waste bucket (15).
  • the invention relates to a self-cleaning double filter device comprising:
  • a thick filter (1) comprising a filter band (2) supported by two rollers (3) that receives juice and waste from the squeezing group (13).
  • the juice and pulp fall on the filter strip (2) from the squeeze group (13).
  • the filter band (2) has a series of holes (14) distributed along the length and width of the same that allow the juice and some minor residue to remain, leaving the pulp on the filter band.
  • the filter band shows movement, which can be continuous or at intervals.
  • they have longitudinal grooves that engage with the inner lips (11).
  • outer lips (10) occupy in height the distance between the thick filter (1) and the fine filter (4) and thus, these outer lips (10) on their return through the lower part of the thick filter, pass tightly between the coarse filter and the fine filter (4) pressing the existing pulp on the fine filter while dragging it until it is poured onto a waste bucket (15), thereby obtaining an impurity free squeeze since it is screened by a fine filter, efficient since the residues are pressed against the fine filter and, at the same time, an automatic cleaning of the fine filter without the need for manual cleaning operations constantly.
  • the outer lips (10) are arranged in rows, preferably parallel to each other. Each row comprises lip segments and gaps alternately.
  • each lip of a row corresponds to a gap of the two adjacent rows and each gap of a row corresponds to two lip segments of the respective adjacent rows.
  • the effect of this arrangement is to drag the pulp so that the excess that escapes from each side of a lip segment when being dragged, is picked up by a lip segment of the next row that drags it which, in the case of the filter thick, it means the possibility of a longer residence time on the thick filter (1) allowing a greater obtaining of juice by gravity and movement of the pulp and, in the case of the fine filter (4) it allows to move the pulp and compress it successively in different lips favoring the efficiency of squeezing.
