Definitions

  • This invention relates to mixing machines, and aims to, provide certain improvements therein.
  • the invention is particularly directed to machines of the type of the well-known Banbury 6.
  • mixer which usually comprises two rotors mounted in semi-cylindrical troughs, the rotors being adapted to smear the product to be mixed against the cylinderwalls.
  • the feed in this type of mixer is usually arranged at the top of the troughs and 10 between the latter. It customarily comprises a .hopper for receiving the products to be mixed which is'connected with the troughs by a neck, a weight being provided to press the products downwardly through the neck into the troughs.
  • themass about to be fed is apt to become very sticky, and as it is not subjected during its 3,5 progress tolthe cylinders to pressure, this preliminary heating not only interferes with the feed, but produces in the final batch, portions which 7 are of different chemical or physical characteristics.
  • the pressure exerted by the feeding weight is, of course, very light as compared with the pressure in the cylinders, the feeding weight being designed merely to assist in feeding.
  • Figure 1 is a vertical section of a mixer of the type described, taken through the rotors and through one end of the neck opening.
  • Fig. 2 is an enlarged sectional view oi the water cooling system which we prefer to use.
  • Fig. 3 is a section taken on the-line 33 in Fig. 2, partly broken away.
  • Fig. 4 is a horizontal section. .75
  • Fig. 5 is a sectional view of a modified form.
  • troughs B and C of semicylindrical form which are usually water-jacketed, as shown.
  • rotors E andF which are so shaped as to smear the product to be mixed against the cylindrical walls of the troughs in such manner that the product is passed freely from one trough to another and back again.
  • neck G Leadingfrom the top of the troughs and mid-way between them is the usual neck G, which ordinarily is a plain rectangular passage formed in the same casting as the trough and usually constructed of a length which is similar to that of the rotors.
  • neck section G On the top of the neck section G is a hopper H in which the products to be mixed are loaded, and at the rear.
  • this liner comprises a casting K having a smooth interior, and having at its top a funnel-shaped 110 flange L, while at its bottom it is provided with a flange M of any appropriate shape. the two flanges extending from the body portion of the casting outwardly, and having such dimensions that they fit the interior of the neck G.
  • a space N which lies between the body portion and the inner side of the neck G. This space is utilized to accommodate a water-jacket O, the pre-.
  • This water-jacket may be formed in one, two or more sections, but in the preferred form it is constructed in one section, as best seen in Fig. 4.
  • This section is rectangular, and is provided with inturned flanges P P at the top, bottom and sides, which after assembly contact with the outer wall of the body portion K to form a closed water passage Q.
  • Sheet metal is best used for the waterjacket, and this is united to the body K by welding, brazing, or any other suitable method.
  • the invention in the preferred form of the invention we utilize a construction in which a liner is heat insulated from the neck.
  • a liner is heat insulated from the neck.
  • the form of insulation which we prefer is that of an air spacewhich may be more or less confined.
  • the chamber Q constitutes one such space, but in any event we prefer the construction in which the jacket 0 does not contact with the interior wall of the neck but is separated by a space E preferably extending completely around the liner.
  • heat insulation may be secured by backing the space with any insulating material.
  • the liner is preferably of cast construction, and in order that it may be adequately secured to the interior of the neck G, it is formed with a series of spuds or projections R which are tapped and adapted to receive set screws S, S passing through the exterior of the neck, as best seen in Figures 1 and 2.
  • the jacket 0 will be provided with openings fitting over the spuds and welded thereto. These spuds do not materially interfere with heat insulation above referred to.
  • Suitable provision is made for introducing and discharging water from the chambers Q, such as the ingress pipe T (Fig. 4) and the exit pipe U (Fig. 3). These pipes are screwed into the jacket 0 through holes which are made in the neck G.
  • the pipes T and U are also indicated in Fig. 1.
  • the water-jacket is preferably reinforced by plates V, at the connections of the pipes, as best illustrated in this figure.
  • the material which passes down through the funnel mouth L of the liner strikes a zone of coolness which so affects it as to permit it to be fed into the mixing chambers, and thus much facilitates the feed of the product.
  • an insulating air space A is provided in this construction.
  • the weight I shall be reduced in dimensions, so that it will fit thesmaller opening occasioned by the restriction of the normal capacity of the neck. It is also advisable in some instances to water-cool the weight to some extent, as by the passage Y,-
  • a machine for plasticating phenol compounds or the like comprising plasticating means, a feed opening, a passage leading from the feed opening to such plasticating means, and a separable liner for such passage, said liner being formed with water passages.
  • a machine for plasticating phenol compounds or the like comprising plasticating means, a feed opening, a passage leading from the feed opening to such plasticating means, and a separable liner for such passage, said liner being formed with water passages, and comprising a casting fitting into said passage and a jacket fitted to the exterior of the casting and arranged between the latter and the wall of the feed passage.
  • a machine for plasticating phenol compounds or the like comprising plasticating means, a feed opening, a passage leading from the feed opening to such plasticating means, and
  • a separable liner for such passage said linerbeing formed with water passages, and comprising a casting having a tapered top fitting in said passage, and a sheet metal jacket arranged about the exterior of said casting between the latter and the wall of the feed passage.
  • a machine for plasticating phenol compounds or the like comprising two troughs, rotors in said troughs, a hopper above the troughs, and a neck between the hopper and the troughs, water-jacketing means arranged at said neck, and insulating means also arranged at the neck between the body of the machine and the material.
  • a machine for plasticating phenol compounds or the like comprising plasticating means, a feed opening, a passage leading from the feed opening to such plasticating means, such passage being substantially spaced apart from, and largely heat insulated from the body of the machine on all sides of the passage.
  • a machine for plasticating phenol compounds or the like comprising plasticating means, a feed opening, a passage leading from the feed opening through such plasticating means, such passage being substantially spaced apart from, and largely heat insulated from the body of the machine, such insulation comprising an air space substantially surrounding the passage.
  • a machine for plasticating phenol compounds comprising plasticating means, a feed opening, a water-cooled passage leading from the feed opening to such plasticating means, and means for substantially insulating such watercooled passage from the body of the machine.
  • a machine for plasticating phenol compounds comprising plasticating means, a feed opening, a water-cooled passage leading from the feed opening to such plasticating means, and means for substantially insulating such watercooled passage from the body of the machine,
  • a feed opening a passage leading from the feed opening to such plasticating means, a separable liner for such passage, said liner being formed with water passages and comprising a casting fitting into said passage and a jacket fitted to the exterior of the casting and arranged between the latter and the wall of the feed passage, and said jacket being separated in large part from the wall of the feed passage to provide heat in sulating means for such liner.
