Title: Chemical cleaning bath waste water evapn. - by using hollow body with external flame heating for simple action with easy cleaning and heat for stations
IPC: C02F1/04
Filed: 1991-12-21
Abstract: The evapn. zone is a hollow body with external gas or oil flame heating, without heating surfaces in the body. The exhaust heat from the burners is used as a heating gas for other station(s) to give surface treatments, e.g. paint or powder coating units, to give (in)direct heating. The outer surfaces of the evapn. zone pref. have heating ribs or other additional heaters which may be used to eliminate the need for cycling emitted heat. Heating surfaces may be included in the hollow evapn. zone and/or flame heated internally as a heat exchanger heated directly in an oil or gas burner. The zone is shrouded by an insulating mantle, with a gas or liq. mantle, where the gas or liq. may be used to deliver the heat elsewhere or used as a coolant and released. The exhaust heat from the combustion gas may be used (in)directly to heat the rinsing water and waste water, or passed through a heat exchanger for cooling and the heat used to raise the temp. of other installations. The generated vapour gives (in)direct heating of baths and/or other components unconnected with the paint or powder coating stations. USE/ADVANTAGE - Used for stations used to clean components chemically, before they are painted or powder-coated or electroplated. The system has a hollow body for the evapn. zone in a simple geometric shape, without internal heating surfaces to give easy cleaning, and gives a heat supply for other work stations.

Title: Solid and liq. waste recovery - comprises adding dry matter contg. top gas dust to homogenised mixt. for thermal processing
Inventor: OSING DIRK A
IPC: C02F11/12
Filed: 1992-02-20
Abstract: To process a mixture of solid and liquid waste materials which cannot be used or is difficult to use containing at least one metal and especially Fe and/or its compounds and especially oxides, it is initially homogenised. To the mixture is added at least one fine-grain dry material, which at least contains top gas dust, in sufficient volume to build up clumps which, at least partly can be recovered in a thermal process. The dry additive is fed to the mixt. in a volume where the mixture can be sorted to give at least one fraction of matter which can be recovered in a thermal process. The waste material is mixed before the dry matter is added, and is homogenised by stirring. After mixing, a second mixture can be added at a different grain size and/or fluid content and in another condition, and of a different composition, and they are mixed together before the dry solids are added. Roller scale sludge or residue from the pigment industry are used for the first and/or second mixtures, or black sludge from aluminium mfg or processing, or sludge from the processing of pyrites. The first and/or second mixture contain at least one of the component from a top gas sludge, or sinter dust, or sinter sludge, or converter dust, or grinding sludge or dust, foundry dust, or dust and sludge from metal working. The top gas dust is taken from a blast furnace to smelt iron ore. A dust with a carbon content is also used with the dry matter, to adjust the carbon content of the mixture(s), using coke dust, lignite dust, or mineral coal dust, or a calcinated lime or material which produces calcinated lime at high temps. After sorting, the mixture material is pelletted and the pellets are hardened by storage in air and/or by heat. The sorting is for the separation of impurities, and the finer fraction is converted into pellets. A sieve is used for sorting. The material has a consistency which allows it to be conveyed pneumatically to a further thermal processing stage. The material can also be formed into briquettes to by treated by heat. The material can also be given a thermal metallurgical treatment or used for cement prodn. USE/ADVANTAGE - The method is for the disposal of waste from industrial processes such as in the prodn. of granular FeSO4. 7 H2O, TiO2, Fe2O3, Fe3O4 or roller scale sludge and the like. The technique can handle materials in a variety of consistencies and compositions, and amounts of fluid, to convert them into usable materials for recycling.

Patent DE-4211841-A1 (DE)
Inventor: ABT LUDWIG
IPC: F16L59/18
Filed: 1992-04-08
Abstract: The invention relates to cold insulation for components, such as fittings and flanges in insulated pipelines, annular spaces being formed between the ends of the pipeline insulation (2) and the components, and having an insulating cassette with a housing which consists of two half shells (3a, 3b) and which, in the closed state has (at least on opposite ends) passageways for the pipeline (6) and at least one filling opening (16a, 16b) for plastic which can foam up, the open sides of the half shells being closed by means of a flexible film or plastic web (5) which is attached to the edges of the relevant half shells. The insulation according to the invention, which is an improvement on such insulation is characterized in that the annular spaces are covered by jacket covers which are essentially aligned with the out pipeline insulation, and in that the half shells (3a, 3b), which engage around the pipeline insulation of the insulation cassette are finally filled with foam. As a result of these measures, the cold loss is prevented and condensation in the annular space, which encourages corrosion, is prevented even in the event of changing temperatures. <IMAGE>

Title: Fibre bale supply, positioning bales according to type and quantity - uses trolley to place bale(s) at end of bale row on a conveyor to feed the bale breaker
Inventor: LEIFELD FERDINAND DIPL ING
IPC: D01G7/08
Filed: 1992-04-25
Abstract: To position fibre bales on a conveyor, to be carried to a bale breaker, at least one bale is carried by a bale trolley, for the bale(s) to be moved to the trailing end of the line of bales in the direction (A) of movement. The bale(s) is (are) lowered from above on to the conveyor as the trolley is unloaded. A carrier trolley (22) for at least one bale (1a,1b) brings it to the trailing end (1") of a line of bales (1b) on the conveyor (14), to unload it from above directly against the trailing end (1"). The trolley (22) has a holder and an unloader for the bale(s) (1a,1b). The trolley (22) has a wheeled chassis, or it is moved by a chain or the like along a guide path. The bale holder has at least one carrier, such as a base, to support the bale(s) (1a,1b) and at least one supporting wall. The base and/or wall can tilt on a horizontal axis to act as the unloading system to discharge the bale load. The base can be removed from under the bale(s), using a base plate, grid or the like, or a conveyor or roller conveyor as the trolley base. A wall or walls can be shifted to slide the loaded bale(s) clear of the trolley. The trolley (22) can be fitted with a swing holder to grip the bale(s) from above. The carrier frame for the base and the wall can swing on a vertical axis in relation to the trolley (22) chassis. The trolley can ride on rails or carrier beams, which can rotate round a vertical axis with the trolley (22). The trolley (22) can ride along the conveyor (14) which carries the bales to the bale breaker (12). The conveyor (14) carries the bales (1a) being worked and also the reserve bales (1b). Drive motors power the trolley frame movement, the swing mechanism for the supporting wall and/or base, under electronic control which is, itself, connected to the central control such as for the overall fibre material flow. The bale trolley is a driverless vehicle. The bale unloading system can move the bale(s) in one of two directions with a sliding wall or by a pivoting action on a horizontal axis at the bale centre. A conveyor belt, with a variable location, can be the carrier and unloading mechanism, controlled to move simultaneously with the trolley. At least one sensor registers the end position (1") of the line of reserve bales (1b) in the row, to give the trolley delivery point for the fresh bale(s). ADVANTAGE - The system gives increased flexibility in positioning bales in readiness for the bale breaker according to their type and quantity.
