A pug mill having a housing and a cantilevered shaft extending through the housing includes, in seriatim, a vacuum chamber, a wall, a mixing chamber and a reduction cone. A communication port about the shaft is positioned in the wall between the vacuum chamber and the mixing chamber. Vacuum can be maintained within the mixing chamber by air passing through the port. An auger associated with the shaft forces clay toward the reduction cone. This creates a seal for maintaining vacuum within the mixing chamber and extrudes cylindrical blocks of conditioned clay without significant air bubbles. A deflection plate rotating with the shaft and a spiral element about the shaft keep the communication port clear. The shaft is eccentrically mounted. The dividing wall is removable.

A stirring device includes a container, a cleaning liquid supply part for supplying a cleaning solution to the container, a first stirring part including a first stirring rod located inside the container, and having a suction passage provided inside the first stirring rod and a plurality of suction ports connecting the suction passage and the inner space of the container in a fluid movable manner and sucking the cleaning liquid in the container, a second stirring part including a second stirring rod located inside the container, and having a discharge passage provided inside the second stirring rod and a plurality of discharge ports connecting the discharge passage and the inner space of the container in a fluid movable manner, and a cleaning liquid circulation part connected to the suction passage and the discharge passage; and provided to supply the cleaning liquid introduced through the suction passage to the discharge passage.

The invention relates to disperser pumps designed for pumping, intensive mixing and dispersing multi-phase fluids and, in particular, water-mineral binding mixtures and other liquid fluids containing solid particles. The technical result of the invention is a regulated combination of two processes in the same apparatus, such as pumping the working fluids (pump function) and intensive mixing (dispersion/disintegration/homogenization function), with no stagnant zones in the working chamber of the pump, and all surfaces within the working chamber of the pump are self-cleaned during the rotation of shafts. The disperser pump for pumping liquid fluids with solid particles comprises the housing with pressure and suction pipes, in which there are two shafts that rotate in the same direction and have screw threads. In the end of the working chamber, the cam-driven elements are additionally mounted on the shafts in front of the pressure pipe, wherein the shafts rotate at a speed of 800-4500 rpm.

The present invention is in the field of stirring, and particularly relates to a stirring assembly including a rotary shaft and a stirring member. The stirring member is fixedly provided on the rotary shaft. The rotary shaft is provided with a first passage therein. The first passage is formed with an air inlet through one end of the rotary shaft. The stirring member is provided with a second passage therein. The second passage is formed with an air outlet through the stirring member. The second passage is connected with the first passage. In the present invention, when the rotary shaft is rotating, the external air is drawn in from the air inlet and discharged from the air outlet to make the liquid to be mixed by the stirring member with the air discharged from the air outlet.

A mixer includes: a first rotary shaft provided in a housing across a first end and a second end of the housing in one direction; and a first rotary body mounted on the first rotary shaft inside the housing, the first rotary body that conveys a material supplied from a supply port toward a discharge port while mixing the material as the first rotary shaft rotates. The first rotary body includes: a first main body including a first recessed portion recessed in a helical shape; and a plurality of first scrapers provided in the first recessed portion and arranged along the first recessed portion. Each first scraper has a first inclined surface inclined so as to press the material toward the discharge port by rotation of the first rotary shaft.
