Sleeve multilayer filter ELEMENT FOR CLEANING MILK

摘要

The invention relates to filter applications in the food industry, namely, to fluid filtration devices, especially milk. Aimed at increasing the lifetime of the filter element, this is achieved in that the multilayer bag filter element for cleaning the milk is designed as a sleeve 1. The sleeve wall 1 made of food-grade polymer (polypropylene) by thermodynamic extrusion. The walls of the sleeve 1 are obtained by stretching polymer filaments to turbulent air flow of varying thicknesses which randomly intertwined, forming conductive channels, wherein the polymer filaments in the outer layers of the sleeve wall is not sealed prokatochnym shaft and polymeric filaments in the inner layers of the walls of the sleeve are sealed prokatochnym shaft. One of the free ends of the sleeve 1 is provided with a removable cover 2.; At the other free end of the sleeve 1 installed transition adapter as washers 3 with a nipple 4, communicating with the outlet and having an outer cutting for a tight mounting thereon the free end of the sleeve 1. The housing 5 of the device for cleaning the milk inlet pipe 6 is provided on the one hand and the flange 7 with an external thread on the other. On the output side cover 8 is internally threaded in a threaded connection with the housing 5 and the outlet pipe 9. Transition adapter is sandwiched between the inner surface of the lid 8 and the end flange 7 of the casing 5. At the mating surfaces of the transition adapter installed in the annular grooves 10. The sealing ring 1 n.p.f., ill. 2
