Definitions

  • the circulators mounted in the pans can be top-mounted or bottom mounted.
  • the circulator shaft extends through the height of the pan (between 5 - 8 metres) and projects at its upper end through the top cover of the pan (Patent Nos. US387388, USl 133821, US247542, US1785530, GB458882, GB 1061708, EP0065775).
  • the circulator shaft projects into the pan through its bottom wall (Patent Nos. US1476331, US2355397, FR2695837).
  • Long circulator shaft length Increased length of the shaft is associated with several drawbacks viz. a. Load: Increased axial as well as radial loads requiring additional means to counter these loads. b. Vibrations: More Bending vibrations, which in turn have adverse affect on seals, prove particularly troublesome, and require additional and supplemental sealing means (Patent Nos. US5078506). c. Bearings: Bearing life is reduced; d. Accessories: An auxiliary bearing used at the free end of longer shaft to reduce vibrations (Patent Nos. USl 133821, GB247542, US1785530) has been found to create problems of alignment, lubrication, corrosion and maintenance. e.
  • bearings The bearings used in pan circulator assembly are disposed entirely outside the pan to give additional support to long circulator shaft.
  • the bearings are large in size and capacity due to bigger shaft diameter and greater axial and radial loads.
  • the gearboxes used in conventional pan circulator assemblies are of bevel, worm or helical type (Patent Nos. US387388, USl 133821, US1476331, US2355397, DE2922265, EP0065775).
  • the power is supplied by an electric motor.
  • the disadvantages of these gearboxes are as follows: a. High power consumption - High co-efficient of friction requires higher drive energy; b. Heavy weight - require elaborate support structure; c. Large size - require more installation space; d. High Speed Reduction Ratio achieved only at the cost of efficiency and size; e. Radial loads within the gearbox add to that of the circulator shaft; f.
  • the present invention has been able to overcome the disadvantages associated with the prior art mechanical circulators installed in vacuum pans in a simple but novel manner.
  • the innovation involved in the present invention lies in the novel features of construction and, combination and relation of readily available, off-the-shelf components making the bottom-mounted pan circulator assembly compact, reduced in size & weight, cost-effective, maintenance-free and energy efficient.
  • an inline hollow spline planetary gear box 15 eliminating the use of coupling.
  • the gearbox 15 has a hollow input with key arrangement for direct inline flange mounting of the drive 16 without coupling.
  • the use of such a gearbox 15 has many advantages over the conventionally used gearboxes in vacuum pans as follows:

Abstract

L'invention concerne un nouvel ensemble (2) de circulateurs mécaniques présentant une structure compacte et offrant un bon rendement énergétique. L'invention consiste à réduire sensiblement la longueur des arbres (13) des circulateurs qui ne mesurent que 0,50 à 0,56 m, par rapport à une longueur traditionnelle de 5,0 à 8,0 m (circulateurs mécaniques montés en haut) et de 1,7 à 2,5 m (circulateurs mécaniques montés en bas), en plaçant les moyens d'étanchéité et l'ensemble palier dans un logement d'étanchéité et de palier (4) spécialement conçu, disposé à l'intérieur de la cuve à vide, et en utilisant une boîte de vitesses compacte et légère (15) du type planétaire en ligne comportant un arbre de sortie cannelé creux et un arbre d'entrée creux avec un mécanisme de clavetage permettant un assemblage en ligne direct par brides de la transmission (16).
