Briefly described the utility model discloses an operating principle, with a certain amount of kitchen garbage along feed channel 1 enter into below sieve box 5, solid part in the kitchen garbage is blocked by sieve box 5, liquid part among the kitchen garbage flows into collecting box 2, sieve 52's sieve mesh is great, so some less solid parts (generally be food waste, this part can compress) follow liquid part from the sieve mesh and then flow into collecting box 2, then step motor 4 clockwise rotation 90 degrees, sieve box 5 that has solid part enters into the station of rear side, then the work of screening subassembly 9 on the 6 rear sides of support, cylinder 94 drives ejector pin 93 and moves down, ejector pin 93 passes the sieve mesh.

Briefly, at this station: 1. the ejector rods 93 are contacted with a plurality of small compressible parts, and the small compressible parts are soft, so that the ejector rods 93 deform after being contacted, penetrate through the sieve holes along with the ejector rods 93 and fall into the first collection box; 2. the push rod 93 contacts with a plurality of large compressible parts, and after the push rod 93 contacts with the large compressible parts, the push rod 93 deforms and is crushed into a plurality of small parts (such as vegetable leaves and table papers), penetrates through the sieve holes along with the push rod 93 and falls into the first collection box; 3. the push rod 93 contacts with a plurality of large compressible parts, and after the push rod 93 contacts with the large compressible parts, the push rod deforms but cannot crush the large compressible parts (such as meat blocks and table cloth); 4. the ejector rod 93 contacts the incompressible part, and the ejector rod 93 cannot penetrate through the sieve holes; thus, after this station, the remaining portions of the sieve box 5 are the incompressible portion of 4 and some of the larger compressible portion of 3.

Then the stepping motor 4 rotates clockwise 90 degrees, the sieve box 5 enters a right station, the second air cylinder 103 drives the brush plate 101 to move downwards, the brush plate 101 enters the left end of the sieve box 5, the lead screw 105 mechanism drives the brush plate 101 to move rightwards, the incompressible part is swept out, and the incompressible part enters the second collection box 7, because the compressible part in the 3 is collided by the ejector rod 93, the part is deformed and is in a sieve pore, the brush plate 101 cannot brush the incompressible part, then the stepping motor 4 rotates clockwise 90 degrees, the sieve box 5 enters a front station, at this time, the rest part on the sieve box 5 is some larger compressible parts in the 3, the rotary air cylinder 32 drives the compressible part to turn over 180 degrees, then the screening component 9 on the front side of the support 6 works, and the ejector rod 93 ejects the larger compressible parts into the third collection box 8, which is mentioned above: the sieve holes are symmetrical about the center line of the sieve plate 52, that is, after the sieve plate 52 rotates 180 degrees, the sieve holes and the push rods 93 can still correspond to each other, and then the rotary cylinder 32 drives the sieve box 5 to reset.

It is worth mentioning that: some incompressible parts will block the sieve holes, so that they will not enter the second collection box 7 and will be ejected by the ejector rod 93 to the third collection box 8, which is less likely to happen, and they will be separated from the third collection box 8 manually, so that the smaller compressible parts in the oil-water will be screened out by the screen mesh and compressed together with the larger compressible parts in the third collection box 8.
