摘要:
A process and apparatus utilizing the process of the present invention are provided to produce a fast dissolving, thermally sensitive granular product. The process employs a fluidized spray dryer having a fluidized bed of granular particles into which recycled off-sized product is fed after being agglomerated to adjust particle size. The spray dryer optionally can employ a second nozzle positioned above the fluidized bed. The process can be employed in the production of calcium hypochlorite water sanitizing chemical wherein the chlorine is supplied from a hypochlorous acid reactor and lime hypochlorinator.
摘要:
An improved non-bonded framing system in two- and three-dimensional configurations which is rendered capable of rigid frame action by actuation of force-displacement means in specified connections between joined frame members so that controlled force-couples are introduced in the connections whereby strain energy is stored in the system and the connections are locked and rendered rigid and capable of immediate moment transfer prior to application of vertical and horizontal service loads to the framing system.
摘要:
A plurality of rollers is positioned between side members of a longitudinally-split, two-piece bearing race and a backup member that supports the two-piece bearing race along the length of side members. The backup member has angled surfaces such that ends of the rollers are closer to the angled surfaces than are intermediate portions of the roller. The two side members of the two-piece bearing race may be spread apart such that the angled surfaces of the backup member direct the side members of the two-piece bearing race toward the rollers to decrease the roller clearance and to create a preload.
摘要:
A process for removal of discrete particulates from liquids by foam flotation which is readily adaptable to continuous or batch processing. A continuous stream of foam, in which the gaseous medium is subdivided into individual bubbles, each encapsulated in a film consisting of a foaming agent solution, each film being shared with each adjacent gas cell, is pregenerated. The composition of the films of the pregenerated foam may include, in addition to the foaming agent, other agents or reagents useful or necessary for the collection and removal of the solid or solute material being extracted by counter ion action. The pregenerated foam is then introduced at a predetermined rate into the liquid carrying the solids or solutes to be extracted and is dispersed therein. The preformed surfactant films of the bubbles contact and attach the solid particles by counter ion action from the liquid body during the progess of the foam bubbles through the liquid. The loaded foam bubbles are allowed to float to the liquid surfaces where they consolidate into a stable foam layer for convenient removal from the liquid surface. Dissolved materials in a liquid body are similarly extracted by use of film having compositions suitable for ionic adsorption or reagents for precipitation of the soluble material on or within the film.
