摘要:
A dispense tip constructed and arranged to communicate with a material dispensing pump comprises an elongated neck and a molded base having a first portion and a second portion opposite the first portion. The neck extends from the first portion of the base. The second portion is constructed and arranged to abut an outlet surface of the pump. An outermost region of the second portion of the base includes a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump.

A volumetric feeder may comprise a driving unit, a storage tank, a sealing unit, a switch unit and a feeding unit. An interior space of the storage tank is horizontally divided into a feeding space and a preparing space which have the same volume such that the feeding material, including viscous or cement-like materials, in the preparing space is configured to be transported into the feeding space with the same volume at a time to achieve volumetric feeding effect. Also, the feeding material in the feeding space is moved by a piston in a pushing manner thus preventing the feeding material from damage or heating during feeding process.

The invention relates to a method and to an arrangement for feeding fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2). The invention relates also to a controlling means for controlling feeding of fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2) in an arrangement for feeding fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2). The invention relates also to controlling means for controlling feeding of fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2) in an arrangement for feeding fine-grained matter to a concentrate burner (1) or a matte burner of a suspension smelting furnace (2) and to a computer program product.
摘要:
The dispenser disclosed herein serves a single serving of a powdered nutrient contained within a container having multi-servings of the powdered nutrient. The dispenser has a metering device that operates as a ball valve or guillotine to dispense a single serving of the powdered nutrient into a water container. The dispenser also has a support surface that can be lowered and raised back up in order to fit a water container under the metering device and a distal tip of the metering device into a mouth of the water container so that no powdered nutrient spills out of the water container during transfer of the powdered nutrient from the metering device to the water container.

An improved particulate metering system is provided with variable blend, application rate, and section control. The system includes a plurality of particulate mixing areas, each having an air input and a plurality of particulate inputs. A plurality of particulate sources is provided, each being in communication with a particulate input of a particulate mixing area. A separate type of particulate can be in each of the plurality of particulate sources. The system includes a plurality of operated conveyances, each being in communication with a particulate source and a particulate input. Each of the plurality of particulate mixing areas can receive air from the air input and a separate type of particulate, and can discharge an air-particulate mixture. One or more metering controls operably control one or more of the operated conveyances.

摘要:
A method of preparing compounds comprising a plurality of components, the method comprising providing a modular dye meter, introducing component into one or more than one modular batching member of the modular dye meter, where the compound to be prepared comprises the one or more than one component, activating the internal rotor of one or more than one of the batching and delivering devices, thereby causing the internal rotors to rotate in the first direction, where rotation of the internal rotor moves component through the progressive recesses of the batching and delivering device through the corresponding delivery duct and through the dispenser, and thereby into a vessel for containing the compound, causing the rotation of the internal rotor in the first direction to cease, causing the internal rotor to rotate in a second direction, where the second direction is opposite to the first direction, thereby moving component back through the delivery duct into the corresponding batching and delivering device, and causing the rotation of the internal rotor in the second direction to cease.
摘要:
A dispensing apparatus for dispensing a controlled amount of powder, the apparatus comprising a hopper defining an exit aperture; an Archimedes screw rotatably supported in the hopper and configured to expel powder from the exit aperture; an actuator configured to rotate the Archimedes screw; a cover configured to selectively close the exit aperture; and a clutch arrangement between the cover and the Archimedes screw. Movement of the cover is controlled by the Archimedes screw through the clutch arrangement.
