Devices and methods for preparing a slurry for coating onto a substrate. The devices and methods of the present disclosure relate to providing a slurry in a closed volume with at least one passage. The slurry includes a solvent, a powder, and a binder. The slurry can also include a dispersion agent. The slurry is forced repeatedly under high pressure through the at least one passage in a first flow direction and then back through the at least one passage in a second flow direction, opposite the first flow direction. The forcing homogenously disperses the powder and the binder within the solvent. Both sides of the substrate are then coated simultaneously with the slurry extruded from the closed volume after the forcing. Curing of the coated slurry includes freeze drying to preserve the porosity of the slurry on the substrate.

A device is provided for preparing a chemical solution. The device comprises a dissolving bowl having an open top portion for receiving a solid chemical material and a closed bottom portion. A grid member is disposed between the top and bottom portions for supporting the chemical material on a top surface thereof defining an array of grid openings and a flow opening distinct therefrom. A nozzle is positioned proximate the bottom portion and directs flow of an aqueous fluid to contact and dissolve at least some of the chemical material and create a chemical solution thereof n insert disposed proximate the grid member impedes flow of the aqueous fluid through one or more of the grid openings to increase fluid turbulence within the dissolving bowl and/or redirects the fluid flowing from the flow opening to flow in one or more directions over the grid member.

Provided is a slurry manufacturing apparatus including: a mixing unit that mixes a predetermined powder and a solvent in a mixing chamber to produce a slurry; a supply unit that supplies a reaction gas to the mixing chamber when the slurry is produced by the mixing unit; and a circulation unit that recovers a surplus of the reaction gas from the mixing chamber and resupplies the surplus of the reaction gas to the mixing chamber.

Embodiments of the present invention include a blending system that delivers granular material directly from designated storage containers into a blender based on the liquid flow rate into the blender and the blender slurry flow rate exiting the blender. The blending system utilizes a blender controller system in communication with a blender slurry flow meter, a blender liquid flow meter, a conveyor load cell, a conveyor motor, and a conveyor speed sensor, wherein the blender control system is configured to regulate the amount of granular material entering the hopper based on the entrance rate of liquid into the blender and the exit rate of the fracturing fluid slurry from the blender.

A slurry mixer for a battery electrodecapable of maximally simplifying a configuration of a high-speed stirring body to minimize a rotational load, such that a stirring time of the slurry may be greatly reduced and productivity may be increased, preventing a powdery material from being accumulated on an upper side face and an upper surface of a low-speed stirring body, preventing a deterioration in a performance, failure and a reduction in a life span of a high-speed stirring shaft and bearing, and uniformly stirring mixed materials located at inner corners and a bottom of a container, thereby further increasing stirring efficiency.

A dispersion process of adapalene gel preparation, including the following steps: pulverizing adapalene raw material to D50 not more than 10 m and D90 not more than 30 m by dry detection; adding methyl p-hydroxybenzoate, 1,2-propanediol, carbomer 980 and disodium edetate in water, heating and stirring consistently to obtain a matrix in a uniform jelly; adding poloxamer 188, propylene glycol and ethylene glycol phenyl ether in water, stirring and heating to prepare a mixed solution; adding adapalene in the mixed solution prepared, emulsifying at a high speed, then adding to the matrix for thorough stirring; and then adding a triethanolamine aqueous solution for homogenization and stirring. The preparation prepared has good emulsifying and dispersing effect of adapalene, can be expanded on a large scale, and the industrial promotion prospect is good.

A device for preparing a gelatin-based product may comprise a mix tank, a mix pod that is fluidly coupled to the mix tank via a pod spike, and a hot water tank, where the hot water tank is coupled to the mix pod via the pod spike. In at least one example, the pod spike may comprise an outer tube and an inner tube. In one or more examples, the pod spike of the device may comprise a hub, where a first end of the outer tube is coupled to the hub. Further, in some examples, a first end of the inner tube may also be coupled to the hub.

A device for processing oil or gas well waste solids, the device including a pressurizing discharge unit having a casing. The casing includes a solids inlet and a water inlet. The solids inlet receives treated solids into a front end of the casing, where the treated solids are exposed to a reduced pressure in an internal chamber of the casing of less than atmospheric pressure. The water inlet receives water and adds the water to the treated solids in the internal chamber. The casing includes an extruder screw unit, the extruder screw unit having progressive screw sections located inside the internal chamber and corresponding to conveying mixing and pressurizing screw sections. The conveying screw section conveys the treated solids along a long axis length of the extruder screw unit from the solids inlet towards a discharge end of the casing while the reduced pressure is maintained, the mixing screw section mixes the treated solids and the water together to form a paste, and the pressurizing screw section conveys the paste towards the discharge end and generates, in a portion of the casing downstream from the mixing screw section, a backpressure that is greater than atmospheric pressure. The casing includes a die assembly to extrude the paste through an orifice of the die assembly located at the discharge end while maintaining the backpressure on the paste in the internal chamber. Method and system embodiments for processing oil or gas well waste solids are also disclosed.

A device (1) and method for media filtration with a preparation container (2). A chamber (5) containing a dissolvable medium (29) is situated between the container inflow and outflow, and has a filter (22). A mixing arm (6, 7), connected to the inflow, protrudes into the medium in the chamber with at least one mixing nozzle (19, 20), disposed at the free end (17, 18) of the mixing arm for generating a directed jet of solvent. The preparation container has bottom (10) and top (8) parts bracketing the chamber. The filter is a sterile, has on the filtrate side facing the outflow, a circumferential outer edge (23) resting on a circumferential rest edge (37) of the bottom part of the preparation container and is connected fixedly thereto. A sterilised filtrate space (39) is formed between the filtrate side (38) of the filter and the outflow situated in the bottom part.
