A hygienic filter and disposal apparatus comprising a main compartment a base platform, a front end, and a back end, and adapted to contain granular material and waste; a secondary compartment adapted to contain granular material; a door connecting the main compartment to the secondary compartment; and a filter element, comprising porous walls around a cavity and a first opening into said cavity, the walls adapted to filter waste out of the granular material; wherein the back end is proximate to the first opening at a first position where the front end and the back end of the base platform are level; wherein in a second position the front end is lifted higher than the back end and the granular material and waste are directed through the first opening into the cavity; wherein in the second position the filter element retains waste in the cavity and permits the granular material to fall through the porous walls into the secondary compartment; wherein in a third position the back end is higher than the front end and the door opens and directs the granular material into the main compartment; and wherein the device is adapted to sequence from the first position to the second position to the third position.

A self-cleaning, automated apparatus with a filter for fluids includes a nozzle unit assembly that has two nozzle tubes, one inside of another. Each of the tubes has a respective pattern of one or more slots or holes. As the tubes rotate, one with respect to the other, part of the pattern of the one coincides at times with part of the pattern of the other, resulting in a jet of fluid directed toward a filter to remove debris from the filter. The filter is rotated so the jet can reach all parts to be cleaned. The respective patterns of the two nozzle tubes may be an approximation of a helix and/or an approximation of a line.

Methods and apparatuses for screening are provided. Embodiments include a screen basket apparatus for screening material, comprising a grid frame having a plurality of openings arranged in a lattice and a plurality of screening cartridge assemblies affixed to the grid frame to cover the respective openings of the grid frame. The screening cartridge assembly includes a case and a screen assembly fitted into the case, and may be affixed to a set of transversal member of the grid frame. The case may be an injection molded thermoplastic polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across an exterior portion of the grid frame.

The screening cartridge assembly includes a case and a screen assembly fitted into the case, and may be affixed to a set of transversal member of the grid frame. The case may be formed of a single injection molded piece integrally formed by injection molding one of a polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across the exterior of the grid frame, which reduces blinding and is resistant to wear and tear.

A filter extractor may include a first gutter fixed to a tool body and a second gutter being pivotably connected to the tool body. Additionally, a lifting device may be provided on the filter extractor. The lifting device is configured to extend and retract a line through the first gutter and the second gutter to extract a filter from a fluid conduit.

This invention relates to a powder sieving apparatus for a powder coating system and a powder suction system thereof. the present invention provides a powder sieving apparatus for a powder coating system having a powder spray gun, a powder suction pump assembly, and a powder container/hopper. As per the present invention, the said sieving apparatus comprises a housing having at least one outlet connected to a suction side of the powder suction pump and an inlet connected to a suction pipe dipped in the powder container, a cylindrical sieve having a sieve mesh adapted within the housing dividing the housing into an inner and outer compartments, a brush holder rotatably and/or oscillatingly adapted in the inner compartment of the housing for cleaning the cylindrical sieve. The present siveing apparatus provides freshly sieved powder free of large impurities and the powder particles and presented to the charging device such as a powder spray gun and the particles are thus charged better resulting in substantially and better transfer efficiency and this results in lower powder consumption.

A horizontal axis rotary separation apparatus is deployed in a process for separating resinous trichomes rich in flavoring, aromatic and/or medicinal components produced in plant trichome glands from unwanted plant matter. The process physically separates resin rich beads at the trichome gland head from extraneous plant matter by one or move separation sieves. The sieves are provided in or as a casing over a rigid frame member. The sieves are mesh fabric bags or screen that are easily opened and replenished in a batch operating mode, and are removable from the frame for cleaning and maintenance. Other aspects of the invention include processes that improve process efficiency and speed, and yield products of superior quality.
