2 Claims.

My invention relates to an improvement in revolving cone mixers.

The object is to provide a mixer of this general type for completely and uniformly mixing liquid and semi-liquid solutions with the employment of a minimum number of mechanical parts, and in a minimum length of time, by creating circulatory currents and cross-currents throughout the solution, with the purpose in view of reaching every particle with comparative rapidity and all areas substantially alike of the tank in which the material is held while under treatment.

It has been found in practice, when desirable to introduce gas or air underneath the lowermost cone, the air or gashas a tendency to pass up along the shaft and issue at the upper end-of the top cone in spite of the downward flow of the liquid at that point, and to obviate it this present invention includes a baflle which is located at some point on the shaft usually equidistant between the discharge ends of the two cones, but not necessarily at that point as will be hereinafter indicated, the baflie or'bafiles acting as a smaller ends of the cones, and by the use of the baille the tendency of air or gas introduced at the inlet I of the lower cone to follow the shaft and escape at the inlet 6 at the top of the upper 5 cone is prevented, the baflie acting to arrest and divert the air or gas and cause it to enter and discharge with the meeting streams of liquid from the two cones.

The form shown in Fig. 2 differs from Fig. 1

merely in' the dimensions of the two cones 8 and I 9, these being of different lengths and different diameters at the discharge end with the baflie 5 placed midway between the discharge ends, and performing the same function as described in 16 connection with the form shown in Fig. 1.

'form and dimension of the cones in Figs. 2 and 3, is to create a differential in the speed of out- 1 flow from the discharge ends of the cones to insure the meeting of different particles of the cir-- culating mass at the discharge area between the two cones where the material issues at different speeds. x

In t e for shown in Fig. 4, the cones l2 and I3 are of u form size, and two batlies l4 and I5 are employed, one being. located in each cone 80 instead of the single baiile 5 located equidlsl e tantly between the discharge ends of the cones.

In the form shown inFig. 5, the ones l6 and II' are-'of uniform dimensions, and he baifies I8' and I9 are ofconvex-concavo form, their concavities facing each other, and they are shown located partly within and partlywithout the discharge ends of the cones.

divider to divert the liquids and/or gases into the flowing stream leaving the, cones In the accompanying drawings: Figs. 1, 2 and 3 are sectional views showing slightly different forms of cones-with a centrally located baffle:

Fig. 4 is a view showing two baflies, one being located'within each cone;

Figs. 5, 6 and 7 illustrate different forms of bafiles; and

Fig. 8 is a top plan view. The numeral I represents the usual tank in all forms illustrated, and the numeral 2 a rotary shaft common to all-forms, and to which both n the .cones 20 and 2 are of uni-,- cones and bafnes ar e ur d, form dimensions and the baffles 22 and 23 are Referring to Fig. '1, numerals 3 and 4 repre-/ cone-shaped, and located within. the cones 20 sent cones of uniform dimensions secured a' and U, p v y their smaller ends to the shaft 2, whereby to f the form shown in Fig. the. cones 24 and rotate with it, with their larger ends discharg- 25. are of uniform dimensions and the baffle 26 ing toward each other. is in the form of a double cone, centrally lo- 1 A bafile 5 in the form of a disk is secured to Gated On h ,S a t L .the shaft midway between the discharge ends In the several combinations of cones and bafeg' of the cones, and acts as a divider and diverts fi bames, it is n 9 intention to be limited any air or gas horizontally in all directions into as to selection of type and dimension of cone f the discharging streams of liquid which meet at.

or cones, baflie or baflies, but theseveral difthe edges of the battle on their way out between ferent selections shown and described/ are mere the cones. In other words, the baffle is a di- 1y illustrative of the fundamental idea of the vider to divert gases and the liquid into the invention, which is the use. of a baiiie or baf flowing stream leaving the cone. fies of any form located on the shaft at or near It is understood, of course, that the liquid the discharge ends or within the area of the is sucked in through the inlets 6 and I atthe cones of any relative dimensions. i

It may be desirable to make various changes, and even resort to some not illustrated, in the treatment and mixing oi, difl'erent liquid and semi-solid substances, all 01 which are considered within the scope and breadth of this invention, the particular form or baffle employed and its location with respect to the cones always serving the purpose of diverting the course of the material treated including air or gas in order to insure that the entire outflow shall be in one discharging stream peripherally at the opposed enlarged ends of the cones.

I claim:

1. A revolving cone mixer including a tank, a. rotary shaft; cones secured to the shaft with their larger ends discharging toward each other and having inlets at their remote outer ends, and at least one bai'iie located on the shaft within the general area bounded by the two cones, said baifie having smooth and unobstructed surfaces and being of less diameter than the mean diameter of said cones.

2. A revolving cone mixer including a tank, a rotary shaft, cones secured to the shaft with their larger ends discharging toward each other and having inlets at their remote outer ends, and a battle carried by the shaft at a point equidistant between the discharge ends of the cones, said baflle having smooth and unobstructed surfaces and being of smaller diameter than the mean diameter of said cones.
