Description
Claims (8)
- Hydromechanical mixing apparatus for producing a mixture of powder or granular state material and fluid, the apparatus comprising at least one mixing space, a hopper for introducing the powder or granular state material into the mixing space, an inlet pipe for introducing the fluid into the mixing space, circulating means for returning at least one part of the mixture into the mixing space and a pump for delivering the mixture through an outlet pipeline, wherein said at least one mixing space comprises an upper mixing space and a lower mixing space located one below the other, the upper and lower mixing spaces being connected by a conducting pipe having a cross section smaller than that of the upper mixing space, and wherein said circulating means comprise a first circulating system for delivering one part of the mixture from a bottom part of the lower mixing space into the lower mixing space, characterised in that said circulating means further comprise a second circulating system (18, 21) for delivering another part of the mixture from the bottom part of the lower mixing space (12) into the upper mixing space (11).
- The apparatus according to claim 1, characterised in that the second circulating system (18, 21) comprises a second circulating pipeline (21) having an end protruding into the upper mixing space (11), said end being divided into jet pipes (24) arranged in a way symmetrical to an axis of the upper mixing space (11) and directing mixture jets into a space (13) confined by the conducting pipe (14).
- The apparatus according to claim 2, characterised in that the second circulating system (18, 21) comprises a second circulating pump (18) delivering an amount of the mixture so that the mixture jets fill up the total cross section of the conducting pipe (14).
- The apparatus according to any of claims 1 to 3, characterised in that the first circulating system (19, 22) comprises a first circulating pipeline (22) having an end arranged in a way introducing the mixture tangentially at one or more locations into an upper part of the lower mixing space (12).
- The apparatus according to any of claims 1 to 3, characterised by further comprising a baffle member (16) located in the lower mixing space (12) below the conducting pipe (14), said baffle member (16) having a baffle surface with a conic shape or with a shape of increasing steepness towards its tip.
- The apparatus according to claim 1, characterised in that the upper mixing space (11) is shaped axially symmetrically in a way narrowing downwards, the inlet pipe (26) is connected tangentially to an upper part of the upper mixing space (11), and the hopper (15) is connected in the direction of the axis of the upper mixing space (11) to the upper part thereof.
- The apparatus according to claim 1, characterised in that the outlet pipeline (23) is connected to the first circulating system (19, 22).
- The apparatus according to claim 1, characterised in that the lower mixing space (12) is fitted with a venting pipe (17) for exhausting gaseous materials.
