FIELD: agriculture. SUBSTANCE: milk filter has milk receiver 1 with inlet pipes 2 and outlet pipes 3 positioned at different levels in milk receiver 1, and coarse filter 4 positioned between pipes 2 and 3. Lower part of receiver 1 is made conical and has conical plug 5 with stem 6, which abuts against bottom of sump 7 loosely connected to receiver 1, which is communicated with fine filter casing 8 through outlet pipe 3. Casing 8 has cylindrical chamber 9 with longitudinal side slit 10 and discharge pipe 11. Filtering member 12 mounted within casing 8 is fixed on outer surface of squirrel-cage type device 13, whose inner surface is provided with ribs 14. Lower part of device 14 is formed as piston 15 with shank 16 having helical side surface with high angle of lead. Nut 17 is seated onto shank 16. Supporting sleeve 18 with guiding openings 19 is positioned in lower part of casing 8. Device 13 and nut 17 are spring-loaded by springs 20 and 21, respectively. Bottom of casing 8 is provided with drain hole 22. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 dwg |
