Abstract: The present invention relates to a retractable device for loading particles of material into a tank, the device comprising: a hopper, a pulley, and a sleeve connected to the pulley. The hopper is configured to receive particles of material and to direct the received particles into the sleeve. The sleeve is configured to carry the particles of material received from the hopper into the tank. The length of the sleeve inside the tank is adjustable by rotating the pulley.

Abstract: The present invention relates to a conveying line for the pneumatic conveyance of materials, comprising: at least one flexible part; at least one rigid part; and at least one gas injecting device installed in at least one of the rigid parts, wherein the at least one flexible part and the at least one rigid part are intercalatedly connected.

Abstract: The present invention relates to a receiving assembly for particles of material to be loaded into a tank, the assembly comprising: a receiving equipment configured to receive and store the particles of material; at least one gas injection device connected to the receiving equipment; and at least one valve configured to open and close at least one outlet of the receiving equipment, wherein the at least one gas injection device is configured to generate a gas flow that passes through at least one valve while it is open. The present invention also relates to the use of the receiving assembly in loading tanks, to a method of loading tanks and to a system comprising the receiving assembly.

Abstract: The present invention relates to a receiver device comprising: a housing; an outlet; at least one inlet configured to be coupled to at least one pipeline of at least one pneumatic conveyance system; and at least one flexible barrier arranged inside the housing, configured to reduce the velocity of particles of material arriving transported by the at least one pneumatic transport system, from the at least one inlet to the outlet.

Abstract: The present invention relates to a system, method, and use for the unloading of solid material particles used in a physical, chemical, and/or biological process in a tank and for the inertization of the tank. The receiving tank and the pump are fluidically connected. The inert gas supply device is fluidically connected to the tank and to at least one injector. The at least one injector is arranged along the transport line that connects the tank to the receiving tank and is configured to inject inert gas into the transport line. The pump is configured to generate negative pressure in the receiving tank and in the tank, and the inert gas supply device is configured to insert inert gas into the tank and supply inert gas to at least one injector, to allow the displacement of solid material particles from the tank to the receiving tank.

Abstract: The present invention relates to a system for loading and unloading agents in the form of particulate solid material, used for carrying out a physical, chemical, and/or biological process in one or more tanks. The system includes: an intermediate tank, a pump, and a pneumatic conveyor. The intermediate tank and the pump are fluidically connected. For unloading a tank containing saturated or degraded solid material particles, an empty or partially empty solid material tank is fluidically connected to the intermediate tank and the tank containing saturated or degraded solid material particles. For loading a tank, a solid material tank containing unsaturated or undegraded solid material particles is fluidically connected to the intermediate tank.
