Definitions

  • the invention relates to a method and an apparatus for Deacidify books or the like being the opened book via a gas flow with a basic or basic powder is applied.
  • a method and an apparatus of the generic type Art are known for example from DE 44 36 635 C2.
  • diethyl zinc is used as an alkaline gas for used the treatment.
  • this procedure leaves one unwanted smell in the books as well as an iridescent part Discoloration of the covers.
  • the high temperatures are also problematic to watch the books because of the exothermic process are exposed.
  • negative long-term effects cannot be quite Any later storage of the books is excluded Require in dark rooms. Beyond that could not economically enforce this procedure because of the high costs.
  • the system thus does not have the disadvantages that occur with wet processes, such as a lack of alkaline reserve or Half-moon effect "on but the books are subjected to a relatively high mechanical load.
  • the books are also subjected to a relatively high handling stress, which is due to the individual book handling and the necessary machine change. Since this method also only a subjective control of the amount of base anhydride in the book is carried out, it may happen that the books are enriched with active ingredient powder after treatment.
  • the object of the invention is a method and to create a device that is fast, effective and nevertheless extremely gentle deacidification of books at a lower cost Executability enables.
  • the treatment method according to the invention is of the generic type a dry method and avoids the disadvantages of wet processes described. This distinguishes itself from other known drying processes Procedure characterized in that the books in the work preparation in a Book cassette inserted and fastened with an opening angle of 90 ° become.
  • This multi-book cassette is in a treatment chamber arranged, which are hermetically sealed from the outside and in which a treatment of the books in four successive Phases takes place without relocating the books and a change of the machine would be necessary.
  • a transport medium for the alkali anhydride powder e.g. MgO
  • air is used which is cleaned is returned to the atmosphere. It becomes reliable avoided that operating personnel come into contact with the active ingredient powder reached.
  • a special feature of the method according to the invention is that Books are deacidified in a vacuum preferably at a pressure of about 300 mbar. This makes it possible to use a conventional one Procedures to get by and the air flow significantly lower thereby drastically reducing the mechanical stress on the books. Since the books according to the invention by means of air circulation from two opposite Pages are blown through, it is possible to create a defined one Air volume to saturate with a precisely specified amount of powder and up this way to ensure that the book only the really necessary The amount of powder is supplied taking into account an alkaline reserve.
  • a book cassette carriage 22 arranged, for example, ten book cassettes 23 takes up, of which only the outer ones in FIG. 2 are drawn.
  • the book cassette carriage 22 has wheels 24 and a clutch 25, which is used for connection to a drive device A which the Book cassette carriage 22 periodically back and forth in the treatment chamber 21 moved so that the book pages make a fanning motion. This makes an extremely uniform one, which will be described below It is possible to apply active ingredient to the individual book pages.
  • the book cassettes 23 include side walls 26, depending on the book thickness are adjustable, which are arranged at an angle of 90 ° to each other are what leads to an optimal fanning out of the lying arranged books 27 leads.
  • the books to be treated 27 are in the Book cartridges 23 inserted and attached to the book cover (cover).
  • the Book cartridges 23 are padded, so that the books are optimally protected 27 is guaranteed.
  • the books 27 With the help of the carriage 22, the books 27 brought into the treatment chamber 21. About the clutch 25 Drive device 3 coupled. Then the treatment chamber 21 hermetically sealed. By pressing a start button a PLC control is started.
  • the books 27 are dust and loose particles.
  • the circulating air motors 2, the horizontal motor 3 for driving the book cassette carriage 22 and the suction motor 11 switched on. Once this reaches its maximum speed of rotation solenoid valves y1, y3 and y4 are opened. Thereupon air flows into the treatment chamber. Using the circulating air motor 2 preheated air (maximum 35 ° C) flows through the books 27 and ventilated the pages. Loose particles are removed and sucked away. After expiration The valves y1, y3 and y4 become a predetermined time interval closed.
  • the treatment phase the vacuum pump 9 switched on and valve y15 opened and a vacuum of 300 mbar set.
  • the circulating air motor 2 and the heating run at the same time. That's how the books are kept warm. After reaching a negative pressure of 300 mbar valve y15 closes and the vacuum pump 9 stops. The valves y5 up to y14 briefly open in succession and through one generated in this way The powdered alkali anhydride in the containers 1 becomes a short burst of air up to 10 (6) whirled up.
  • the whirled up powder is sucked into the treatment chamber 21 and injected into the books 27 through the nozzles 28, in the form of a turbulent flow. This process is repeated until the Air pressure increased to 600 mbar.
  • the rotary motors 2 whirl the powder through the books 27, which are moved back and forth and distribute it evenly on all sides.
  • the paper is saturated with the powder.
  • the conditioning phase is used for this worried that to form a lye due to the injected powder sufficient moisture is available, especially since the previously created Vacuum ensured that the books had the natural residual moisture was withdrawn.
  • a water ring pump is used during the treatment phase 4 turned on which generates steam.
  • the steam generated can escape through valves y1 and y2.
  • the valve y1 is then closed and the control valve y3 slowly opened and steam into the treatment chamber 21 moved in. Because the air in the treatment chamber 21 is kept warm, the steam on the book pages do not condense and penetrate the paper. The steam will last sucked in until a pressure equalization at approx. 1000 mbar is reached. Then valves y2 and y3 are closed and water ring pump 4 is switched off.
  • the cleaning phase the Books 27 cleaned of the excess powder.
  • the circulation pump 10 turned on in a separator 7. Spray nozzles all Air vents with water.
  • a suction motor 11 is switched on.
  • the Valves y1, y3 and y4 are opened.
  • the air flows through the treatment chamber 21 and takes loose powder particles with it.
  • the separator 7 the air is separated from the powder dust and clean into the atmosphere returned. All valves close after a specified period of time and the engines shut down.
  • the treatment chamber 21 can be opened and the book cassette carriage 23 can be removed with the books 27. It will now be an optical one Control carried out and, if necessary, individual books 27 cleaned up. A pH measurement is also carried out to check for this Way to do a success check.
