摘要:
The present invention relates to a pneumatic transport system of granular material, destined to convey granular material from one or more storage containers T to one or more processing machines M, comprising: - at least one loading device 10 of the granular material, provided with a collection tank 20 of the granular material; - at least one conveying duct 100 of granular material which fluidically connects the collection tank to at least one container; and - means 110, 35 of generating inside the conveying duct a flow of granular material. The system comprises for each loading device at least one sensor 51, 52 to detect vibrations induced by the material being loaded inside the loading device. Such at least one sensor is arranged in the proximity of or at the loading device and generates time signals of the vibrations that may be correlated to the mass of granular material which is progressively being loaded in the tank or to the volume of the tank being progressively filled by the granular material. The invention also relates to a control method of a pneumatic transport system of granular material.
摘要:
A hopper for dehumidifying loose particulate material, of the type constituted by a container (17) for the particulate material, which is provided, in an upper region, with a covering (15) provided with a manifold (19) for loading the hopper (10); an air dehumidification device (12) being functionally connected to the hopper; an area for venting the air (20) that is present in the container (17) being provided on the covering (15) and being functionally associable with the intake of the air dehumidification device (12). The hopper further comprises air filtering elements (24) which are arranged substantially at the venting area (20).

The present invention relates to a dehumidifier for plastic materials (11) in granules that comprises a container (12) for molecular sieves through which the moist air that arrives from a container (10) of plastic granules (11) must pass. The molecular sieves are arranged inside the container (12) along a ring (14) through which the air flows axially.
摘要:
A distribution manifold (10), particularly for the automated selective connection of a plurality of storage containers to a plurality of molding machines, comprising a central connector (14) which is interposed between a first section (16) for drawing plastic material from the containers (17) and a second section (18) for conveying the material toward the machines, at which it has, respectively, an inlet (21) and an outlet (22). Each one of the first and second sections comprises a respective first and second series of couplings (24,25), each of which can be connected to the end (27) of a duct (28,29) and can be moved by an actuation means (30). The actuation means selectively actuate each one of the couplings of the first and second series, along planes which are radial with respect to the corresponding opening of the central connector (14), from a retracted inactive position to an active position in which the coupling is inserted in the corresponding inlet/outlet of the central connector (14).
