A device for establishing an optimal material flow rate through a material convey line in which a pressurized fluid flow is used to convey material entrained within the fluid passed through the convey line is disclosed. The device includes a plate defining an orifice therein, and a latching mechanism for detachably connecting the plate to an o discharge opening of the material convey line. A gasket is disposed on a first side of the plate and extends along the periphery thereof, and is adapted to be received on and sealed to the discharge end of the material convey line when connected thereto by the latching mechanism such that the fluid flow may pass through only the orifice within the plate. The orifice is sized and shaped to establish a fluid flow backpressure within the material convey line, when the plate is connected to the material convey line, which equates generally to the transport of material therethrough for optimizing the fluid flow parameters within the material convey line without having to otherwise pass the entrained materials therethrough. The device also includes an elongate tubular body having a first end and a spaced second end, the orifice plate being affixed along its first side to the second end of the tubular body.

Device for establishing optimal material flow rate for unloading materials

A method and apparatus for establishing the proper gas flow to pneumatically convey materials from a storage location. The device includes a plate of a size to be complementarily received over a discharge end of a convey line and connected thereto. The plate defines an orifice extending therethrough so that the orifice allows fluid communication between the convey line and atmosphere. The system blower then is used and the speed of the blower is set to establish a predetermined pressure. The blower is stopped, the device is removed, and the blower is restarted at the same speed as set using the device, which is the optimal unloading gas flow for that material.

Method and apparatus for establishing proper gas flow for unloading materials

A system for transporting and unloading dry chemicals in a container including a removable bulk head and a liner. The bulk head has a top and a bottom. The bulk head is tilted when installed in the container such that the top of the bulk head is at the back of the container and the bottom of the bulk head is recessed into the container. The bulk head has an opening at a bottom center portion thereof. The liner has an opening and fits within the container. The liner has a funnel extension fitting through the opening in the bulk head. The funnel extension has a diameter which decreases toward the opening in the liner, with increasing distance from the bulk head. The funnel extension extends across substantially the entire width of the container. The container has a height, and the removable bulk head has a length extending between the top and the bottom, which length is greater than the height of the container. The system also has an adapter which attaches to the liner. The adapter has a hollow main body having an input and an output and a hollow interior. The opening in the liner fits inside the input of the main body. The adapter has an access door attached to the main body between the input and the output for allowing access to the interior of the main body.

System for transporting and unloading dry chemicals

Disclosed is a substantially vertically disposed vessel for the continuous gravity plug flow of solid particles and countercurrent flow of fluid, the improvement comprising the vessel having at least one fluid inlet and a fluid distributing member communicating therewith and extending therefrom for the introduction of fluid into the vessel, the fluid distributor being of a generally inverted V-shape to provide for the substantially uninterrupted mass plug flow of particles past said distributor and discharge of gas out the bottom.
