Tube digestion diaphram pump slurry dispenser

The utility model relates to a distributor for membrane pump discharge material slurry digested form a pipeline during a production process of aluminium oxide by a bayer's method. The utility model is characterized in that: the distributor is a shell having two opposite sides provided with a plurality of feeding holes and a plurality of discharging holes corresponding to the feeding holes. The distributor for membrane pump discharge material slurry digested form a pipeline can be a cylindrical shell or a square shell which is arranged between a digestion pipeline and a membrane pump. The discharge material of the membrane pump enters the distributor first and then is distributed by the distributor at equal quantities to the digestion pipeline, so even though the pump goes wrong and can not work, the digestion pipeline can still get enough slurry form the distributor, resulting in no large difference in the coating speed of the digestion pipeline, thereby prolonging the operation cycle.
