An apparatus for preparing a medical solution by adding substances present in solid molded bodies to a solvent comprises a mixing container, which can be filled through an inlet with a solvent and from which the solution can be supplied to an application via an outlet, and which also has a feed port, through which the solid molded body can be introduced into the mixing container, as well as a dosing apparatus for controllable selective addition of solid molded bodies or parts thereof with different ingredients and/or different concentrations of ingredients from one or more storage containers, in which one or more corresponding receptacles of the apparatus are stored and in which the solid molded bodies are stored in such a way that they can be removed. The apparatus may also have a code detection device for detecting and analyzing a machine-readable code associated with a storage container, said code containing information about which ingredients are contained in the solid molded bodies stored in the respective storage container.

A system for mixing a liquid with a powder into a solution batch includes a hopper (20) into which said powder is deposited, the hopper (20) having a powder outlet (22) therein. A mix tank (60) is also provided having a liquid supply inlet (62), a recirculation inlet (64), and a solution outlet (66). A mix pump (40) that is in fluid communication with the solution outlet (66), the powder outlet (22), and the recirculation inlet (64) operates to mix and transfer the solution.

A system for making a brine solution is provided comprising: a single conveyor; and a hopper assembly configured to receive a salt and a solvent, the hopper assembly comprising a lower hopper having a shape in which sides of the lower hopper direct any solid contents of the lower hopper, under a force of gravity, towards an entry point of the single conveyor, the hopper assembly further comprising a solvent inlet arranged to spray the salt, wherein the solvent inlet is configured to create a brine solution from a spray of the solvent combined with the salt in the hopper assembly, and wherein the single conveyor is configured to remove debris from the hopper assembly at the entry point of the single conveyor. A novel sediment tank is also provided.

Systems and methods for blending fluids are provided. A blended fluid may be obtained by mixing a first fluid from a first fluid source with a second fluid from a second fluid source. The blended fluid may be pumped by a pump arranged downstream of a point at which the first and second fluids are mixed, wherein no other pumps are upstream of the pump. First and second flow control valves that control the flow rate of the first and second fluids, respectively, are adjusted so as to reach a target flow rate of the blended fluid, the blended fluid having a target blend of the first fluid and the second fluid.

The present disclosure provides a fracturing fluid mixing equipment including a clear water supply system, at least two mixing systems, at least one powder tank, at least two powder conveying systems, a mixing tank, a feeding system and a power system. The clear water supply system has two parallel water supply paths which are connected to the mixing system and the mixing tank respectively. The powder conveying system is connected to the powder tank. There are same number of powder conveying systems and mixing systems which are connected in one-to-one correspondence. The mixing system is connected into the mixing tank. The feeding system adds powder by pneumatic conveying. The power system provides driving force by pure electric power and/or electro-hydraulic power. According to present disclosure, the power system can reduce fuel consumption and exhaust emissions. The feeding system can be compatible with various adding conditions of powders in different packaging, which can reduce the possibility of dust pollution, thereby reducing labor costs and occupational injuries and being more efficient and environmentally friendly.
