Description

The utility model relates to equipment for mixing bulk materials and can be used in the construction, chemical, pharmaceutical and other industries.

Known vibration mixer of bulk materials (Engineering. Encyclopedia. Machines and apparatus of chemical and petrochemical industries. T. IV-12 / Under the general editorship of MB Generalov - M .: Engineering. 2004 - 832 S., Fig. 2.2. 17 p. 149), comprising a mixing chamber located on the springs and equipped with a vibration exciter, a loading device and an unloading pipe, in which the loading device is made in the form of a loading pipe located at the top of the mixing chamber. The mixed components are sequentially loaded through the loading nozzle into the mixing chamber and a vibration exciter is activated, which excites the drum vibrations close to circular, due to which the particles of the components acquire relative motion and penetrate from one component to another, providing mixing.

The disadvantage of the mixer is limited performance, due to the fact that in the initial state the components of the mixture are completely separated (one component is completely at the bottom and the other at the top of the mixing chamber) and considerable time is required for their mutual penetration. In addition, the disadvantage is the inability to obtain a homogeneous mixture prone to segregation of materials. The presence of a constantly acting force of weight leads to the fact that small particles have a predominant direction of downward movement, and large ones upward, as a result of which, after reaching a certain uniformity of the mixture, it again begins to delaminate and its uniformity deteriorates.

Known vibration mixer of bulk materials (RF Patent for utility model No. 127658, B01F 9/06, 2013), adopted for the prototype, containing a mixing chamber located on the springs and equipped with a vibration exciter, a discharge pipe and a loading device made in the form of a glass with perforated the bottom, divided by partitions into sectors and placed in the mixing chamber with the possibility of rotation and longitudinal movement on a screw rod.

The disadvantage of the mixer is the limited performance at a given quality of the mixture, due to the fact that in order to ensure high performance the glass must rise along the screw rod quickly enough, which, in turn, leads to the fact that the thickness of the alternating layers of the components increases, leading to increased heterogeneity of the mixture.

The technical result consists in increasing the performance of the mixer and the uniformity of the resulting mixtures of bulk components prone to segregation.

The technical result is achieved by the fact that the vibratory mixer of bulk materials containing placed on the springs and equipped with a vibration exciter mixing chamber with an unloading nozzle and a loading device made in the form of a glass, with a perforated bottom, divided by partitions into sectors and placed in the mixing chamber with the possibility of rotation and longitudinal displacement on a screw rod, equipped with loosening combs with trapezoidal teeth located in the lower part of the partitions, with an external st the bottom of the Rhone.

The drawing shows a vibratory mixer of bulk materials. The vibratory mixer of bulk materials consists of a mixing chamber 1 located on the springs 2 and equipped with a vibration exciter 3, an unloading nozzle 4, a loading device in the form of a cup 5 with a perforated bottom 6 and vertical partitions 7 and with a screw rod installed along its axis and rigidly connected to it 8, coupled to a threaded sleeve 9 located on the bracket 10, rigidly connected to the mixing chamber 1, as well as additional loosening combs 11 with trapezoidal teeth placed in the lower part of partitions 7 from the outside of the bottom 6.

Vibratory mixer bulk materials works as follows. Mixable bulk components are loaded into the lower position of the glass 5 in the sectors formed by the partitions 7. Then, the screw rod 8 is rotated, as a result of which the glass 5 rotates and rises up along the threaded sleeve 9 located on the bracket 10. In this case, the components of the mixture wake up through the perforated bottom 6 of the glass 5 into the mixing chamber 1, overlapping each other in layers. The loosening combs 11 during rotation form grooves in the layer of the previous component, into which the particles of the subsequent component penetrate, providing mixing of the components between the layers. After the components are completely released into the mixing chamber 1, the rotation of the screw rod 9 is stopped and the vibration exciter 3 is activated, which vibrates the mixing chamber 1, as a result of which the mixing process is completed, which requires significantly less time, since the components of the mixture are already significantly mixed during loading. At the end of the process, the resulting mixture is discharged through the discharge pipe 4.
