A mixing silo for bulk material comprises a silo container, a mixing installation mounted in the silo container for mixing the bulk material, at least one shut-off element for shutting off the mixing installation, wherein the mixing silo has a minimum extraction rate and the silo container, with the mixing installation shut off, has a residual cross-sectional area which ensures a mass flow of the bulk material that is greater than or equal to the minimum extraction rate of the mixing silo.

A method for obtaining and applying a sealing gasket element on a slide-valve sliding in a cavity of an apparatus for the recirculation and mixing of chemically reactive polymeric components, comprises the steps of: obtaining from an elastic-plastic material a precursor element of the seal element, with a grid structure having a reticular shape; positioning the precursor element around the slide-valve; exerting on the precursor element, through temporary clamping elements, a radial compression and contraction action to insert it and couple it to one or more housing seats provided on the slide-valve so as to obtain the seal element well coupled to the latter; progressively removing the clamping elements to sequentially release successive parts of the gasket element and gradually free the slide-valve to gradually introduce the parts of the slide-valve—freed in succession—in the housing cavity allowing the sealing gasket element to gradually expand radially due to the elastic return by adhering tightly to the inner surface of the same housing cavity. The special equipment for fitting the sealing gasket element on the slide-valve and the so obtained recirculation and mixing apparatus is also described.

Provided is a chemical injection system for connection to a chemical tank and a process line. The system includes a pump box configured to attach to the tank, the pump box including a body defining an interior, a pump assembly disposed within the interior of the body of the pump box, and an injection assembly configured to be fluidly coupled to the pump box. The injection assembly includes an injection lance having a flange and a stem, a first seal abutting a first side of the flange of the injection lance, and a second seal abutting a second side of the flange of the injection lance.

A blender system may include a base including a motor, a container, and a blade assembly. The blade assembly may include a gear drive. The gear drive may include an input and an output. The input may receive a drive shaft of a motor. The output may drive blades of a blade assembly. The gear drive may alter a rotational speed of the blades relative to a speed of the drive shaft of the motor.

A rotary machine for acting on a process fluid includes an impeller, a shaft, a drive, a seal and a flush casing. The impeller acts on the process fluid and is mounted on the shaft. The drive is connected to the shaft and rotates the shaft and the impeller about an axial direction. The seal has a sealing element sealing the shaft during rotation of the shaft. The flush casing receives a flushing fluid for flushing the sealing element, and delimits an annular flush chamber extending about the sealing element. The flush casing includes a bushing surrounding the sealing element and delimits a radial leakage gap arranged between the sealing element and the bushing. The bushing delimits an axial leakage gap between the impeller and the bushing, and the width of the axial leakage gap in the axial direction is adjustable.

A mixing system includes a container having an encircling sidewall bounding a chamber and extending between an upper end and an opposing lower end; a support plate disposed within the chamber and secured to the encircling sidewall; an inner wall secured to the support plate and projecting within the chamber toward the upper end, an open space being formed between the inner wall and the encircling sidewall; and a first aperture extending through the encircling sidewall so as to communicate with the open space. A mixing assembly is positioned within the container and is supported on the support plate, the mixing assembly including a pliable enclosure and a mixing device.

A liquid analyzing device includes a carrier, a driving unit, a rotating plate and a transmission mechanism. The driving unit is adapted to drive the carrier to rotate. The rotating plate is rotatably disposed on the carrier and adapted to support an analyzing cassette. The transmission mechanism is connected between the carrier and the rotating plate. When the driving unit drives the carrier to rotate to enable a rotation speed of the carrier to be changed and cross a predetermined rotation speed, the rotating plate rotates relatively to the carrier.
