PL99403B1 - DEVICE FOR REMOVING METAL PARTS FROM LOOSE MATERIALS FOR THEIR AIR TRANSPORT - Google Patents

Description

The subject of the invention is a device for removing metal parts from loose materials, especially cement and lime, during their pneumatic transport from cisterns of railroad or road cars to silos located at construction sites or in prefabrication plants. Small metal parts in cement, lime, remnants of clinker grinding, burnt lime, in prefabrication plants are frequent causes of equipment failure: transporting, dosing raw materials, the cause of failure of transport pipe hatches, even basalt clay. the building materials industry is carried out with the help of devices equipped with strong magnets or electromagnets, which "catch" metal parts. They are also commonly used to eliminate lumpy or metal parts from powdered materials, vibrating or shaking sieves. is carried out on the basis of different bulk weights of transported loose materials. The subject of the invention is shown in an example of the embodiment in the drawing, where Fig. 2 shows a longitudinal section of the device according to the invention, and Fig. 1 - an example of the location of the devices between a railway or road tanker and a silo for bulk materials. Powdered materials are transported by means of a pipe 1 passing through a pressure tank 2. The pressure tank 2 consists of two upper and lower parts separated by a porous partition 3. Tank on both sides side is connected by a flexible conduit 6 to the tank 7 and silo 8. The transport pipe 1 on the tank section 2 has an oblong hole 4 cut in the lower part, through which metal parts and lumpy raw material fall onto the grate from the transported raw material. it is compressed air through conduit 9 under a pressure not greater than that of the raw material transported from the tanks to the silos. The air introduced into the lower part of the tank prevents particles of cement, lime or other loose materials from the tanks into the silos from falling onto the grate. 99403 EN
