1. A fracturing fluid mixing equipment, comprising:
(a) a clear water supply system comprising two parallel water supply paths;
(b) at least two mixing systems connected in parallel, each connected to one water supply path of the clear water supply system;
(c) at least one powder tank for storing powder;
(d) at least two powder conveying systems connected to the at least one powder tank, the number of the powder conveying systems being equal to that of the mixing systems, each of the powder conveying systems being correspondingly connected to one mixing system;
(e) a mixing tank connected with the other water supply path of the clear water supply system and an output end of the at least two mixing systems;
(f) a feeding system connected to the at least one powder tank, the feeding system being configured to convey powder from a supply source into the at least one powder tank by means of pneumatic conveying, wherein the feeding system includes an air compressor configured to convey the powder into the at least one powder tank by means of blowing under positive pressure, wherein the air compressor is configured to provide driving air source for a pneumatic component of the fracturing fluid mixing equipment, wherein the fracturing fluid mixing equipment further comprises a dust collecting system connected to the at least one powder tank, the air compressor being configured to provide a back-flushing air source past the at least one powder tank and to the dust collecting system positioned downstream from the at least one powder tank; and
(g) a power system configured to provide driving force by pure electric power and/or electro-hydraulic power.
