Title: Improvements in devices for separating mixtures of liquids
IPC: B01D17/02
Filed: 1954-09-07
Abstract: 769,713. Purifying liquids; gravity-separation apparatus. MULLER, J. Sept. 7, 1954 [April 23, 1954], No. 25960/54. Class 46. Liquid to be purified, e.g. liquid fuel, enters a casing 1 at 2, Fig. 1, and flows through a mass 13 of wood fibres in a chamber 11 forming one arm 8a of a rocker beam. The heavier liquid, e.g. water, is caused to agglomerate by the mass 13 and falls through a slot 17 in the base of the chamber 11 into a trough 18 while the fuel proceeds over a baffle 16 and through a cranked pipe 9 and resilient bellows pipe 10 to an outlet 3. Accumulation of water in the trough 18 causes the rocker beam to tilt about knife edges 6 until the rod 20 of a spring-loaded valve 19 is moved upwards by contact with an abutment member 21 to permit the water to flow from the trough 18 into a collecting cup 22. To prevent the rocker beam from rising again and thus permitting closure of the valve 19 before all the water is transferred to the cup 22 the other arm 8 of the beam, integral with the pipe 9, engages a pawl 28. When sufficient time has elapsed to enable all the water to be drained from the trough 18 the operator in charge of the apparatus releases, from outside, the pawl 28. The arm 8 is engaged by an adjustable compression spring 25 and also carries an upper rod 29 for indicating its position on a dial 32 and a lower rod 37 for closing the inlet valve 33, 34, 35 to prevent turbulence during transfer of water from the trough 18. In Fig. 2 the liquid passes first through a coalescing mass of wood fibres located in a chamber 42 and then through a mass 53, capable of absorbing the final traces of contaminating liquid, located in a chamber 49 on the single arm of the rocker beam. The purified liquid passes through the bellows 50 and fixed cranked pipe 46 to the outlet 48. The controlling spring 55 is in this embodiment connected to the chamber 49, while the inletvalve closing-mechanism comprises a connecting rod 60 connected to a lever (not shown) rigid with one end of a rotatable rod 59 the other end of which has a lever which progressively raises a perforate sleeve 57 to obturate apertures in the inlet pipe 43 as the chamber 49 moves downwards. Such movement serves to indicate, by means of a dial 32, that the material 53 requires replacement. Water passes from the coalescing mass in 42, and also from a hole cut in the bottom of the chamber 49, to a collector cup 44 as before. In both cases discharge of water to the outlet 23 is governed by a float-operated valve 24a. The trough 18, Fig. 1, may include an automatic density-responsive trap connected by a flexible pipe of the bellows type to the outside to evacuate the contaminating liquid directly.

Title: Process and apparatus for bleaching cellulose pulp and similar fibrous materials
IPC: D21C9/10
Filed: 1925-10-21
Abstract: 264,596. Thorne, C. B. Oct. 21, 1925. Bleaching, processes for; gases and vapours, treating with; passing materials through fluid - applying apparatus. - In a process for bleaching cellulose pulp or similar fibrous material, the material is first mixed with bleaching liquid so that it is uniformly moistened but is not free flowing, and then air or other gas is forced through whilst the moistened material is in continuous motion in such a manner that the air or gas is distributed throughout the mass. In a method using a series of bleaching towers 30, 41, 44, the unbleached pulp passes through a concentrator 2 which removes the surplus water, and thence passes to an equalizing tower 3 the purpose of which is to produce a uniform flow to a mixer 5. A rotating scraper arm 58<1> assists the flow to the mixer. The bleaching agent and water are supplied to the mixer from head boxes 13, 23 respectively, a uniform flow being maintained by well-known measuring boxes 20, 27. The mixture then passes successively through the tower 30, 41. 44 where the bleaching action takes place. In passing from one tower to the next, the pulp is led through a combined washer and thickener 36 communicating with a mixer 37 supplied with bleaching agent and water, the operation being the same in each stage. Passing through the bleaching towers is a hollow rotating shaft 45 carrying within each tower a levelling arm 56, a scraper arm 58 and a nozzle 53 through which compressed air is passed into the pulp to drive out the gases of decomposition. The nozzle is preferably situated below the centre of the tower. A water spray 60 at the bottom of each tower assists the removal of the pulp as it is displaced bv the scraper arm. In a modified apparatus. the bleaching of the pulp after passing from the mixer 37 is completed in any known form of apparatus for the bleaching of pulp at low density. The equalizing and bleaching towers are preferably circular in cross-section. In a modification where towers of square cross-section are used, the compressed air is supplied by means of stationary nozzles extending vertically through the open tops of the bleaching towers, and revolving floor grate members are fitted at the bottoms of the towers to assist the discharge of the pulp.
