摘要:
A dense phase pump has two housings that are attached together using a single releasable fastener. The fastener can be released to allow the two housings to be separated thereby providing access to replaceable components. The replaceable components may include one or more pinch valves or one or more barrier elements. A pinch valve for a dense phase pump has a shape or profile for aligning the pinch valve when the pinch valve is installed in a pinch valve body. The pinch valve optionally has two end flanges, with each end flange having a shaped periphery. The two end flanges may have the same size and shape so that the pinch valve can be installed in either of two orientations that are inverse. A dense phase pump has a pump chamber that can be purged by purge gas that enters the pump off-axis from a purge path axis.
摘要:
The present invention relates to a device for conveying at least one fluent material, more particularly in the form of loose material, the device comprising at least one first container (1) for holding the fluent material, the at least one first container (1) having at least one first inlet (4) for introducing the fluent material into the first container (1) and at least one outlet (5) for removing the fluent material from the first container (1), the at least one first container (1) comprising at least one means for the contact-less measuring (20) of the quantity of fluent material in the at least one first container (1). The invention also relates to a method carried out in a device such as described.
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.
