Apparatus for mixing solid and liquid substances

A loop reactor for mixing solid and liquid substances, the reactor comprising

• a. a tube-shaped reactor housing (1) supported horizontally on a foundation;
• b. inlet means (14) at one end and outlet means (10) at the opposite end of said reactor housing;
• c. a guide tube (2) in said reactor housing defining a mixing chamber between said guide tube and the inner wall of said reactor housing;
• d. a tube portion (3) surrounding said guide tube and being connected to said guide tube at the end adjacent said outlet means, said tube portion and said guide tube defining an annular space (5) between them, said annular space being connected to said mixing chamber by openings (6) through which said substances enter into said annular space;
• e. a filling socket (8) having means for filling both said solid and liquid substances connected to the upper side of said reactor housing adjacent said inlet means for filling the substances into the reactor housing;
• f. at least one level control indicator (17) in said filling socket for opening and closing said socket and thereby regulating the level of the substances in the reactor;
• g. a pipe connection (12) and (13) between the reactor housing inlet means and outlet means;
• h. a circulating pump (11) in said pipe connection for pumping the mixture from said outlet means to said inlet means;
• and
• i. a discharge valve (16) connected to said pipe connection for discharging the ready mixture.
