Description

Przedmiotem wynalazku jest uklad regulacji temperatury powietrza zwlaszcza w komorach grzewczych maszyn powlekajacych. Znajduje on zastosowanie przy wyrobie sztucznych skór z tworzyw sztucznych i plandek.Dotychczas stosowane uklady regulacji maja przetwornik osadzony w segmencie komory i polaczony poprzez regulator z zaworem. Wada takiego ukladu jest brak mozliwosci utrzymania stalej temperatury powietrza suszacego, z powodu duzych wahan temperatury plynnego czynnika grzewczego, na przyklad oleju. W zwiazku z czym powstaje czesto produkt zlej jakosci.Celem wynalazku jest usuniecie tych wad.Cel ten osiagnieto dzieki zastosowaniu ukladu kaskadowego skladajacego sie z przetwornika tempera¬ tury osadzonego w rurociagu wlotowym czynnika grzewczego i polaczonego poprzez regulator z zaworem czynnika grzewczego, natomiast w komorze z ogrzanym powietrzem umieszczony jest przetwornik pola¬ czony poprzez drugi regulator z pierwszym regulatorem.Zaleta tego wynalazku jest duza czulosc oraz utrzymywanie z duza dokladnoscia stalej temperatury powietrza suszacego, co powoduje ze produkt jest wytwarzany o wysokiej jakosci, przy malej ilosci braków.Przedmiot wynalazku jest przedstawiony w przykladzie wykonania na rysunku w schemacie ogólnym.W rurociagu wlotowym 1 doprowadzajacym goracy olej jest osadzony przetwornik temperatury 2.Rurociag wlotowy 1 jest polaczony z nagrzewnica 3, która jest umieszczona w segmencie komory 4. Z drugiego konca nagrzewnicy 3 jest wyprowadzony wylotowy rurociag 5, który zaopatrzony jest w zawór 6 poza komora 4. Przetwornik temperatury 2 polaczony jest z regulatorem 7 i zaworem 6. Natomiast drugi przetwornik 8 jest umieszczony w segmentach komory 4 i polaczony z drugim regulatorem 9, który jest polaczony z regulatorem 7 poprzez który oddzialywuje na zawór 6.Dzialanie ukladu polega na tym, ze poprzez wlotowy rurociag 1 doprowadza sie goracy olej do nagrzewnicy 3, która umieszczona jest w segmencie komory 1 i nagrzewa powietrze zawarte wokól nagrzew¬ nicy. Nastepnie olej jest odprowadzany przez zawór 6 rurociagiem 5. Temperatureoleju mierzysie przetwor¬ nikiem 2 przed nagrzewnica 3. Sygnal powstalyw przetworniku 2 na skutek odpowiedniej temperatury oleju, doprowadzany jest do regulatora 7, który steruje zaworem 6 umieszczonym na wylotovyym rurociagu 5.Drugim przetwornikiem 8 mierzy sie temperature powietrza, bedacego w wymuszonym obiegu, w segmen¬ tach komory 4, spowodowanym przez dmuchawe 10. Sygnal w drugim przetworniku 8 spowodowany temperatura powietrza, jest doprowadzony do drugiego regulatora 9, który z kolei nastawia wartosc zadana2 116175 pierwszego regulatora 7 i oddzialywujac na zawór 6 reguluje przeplyw podgrzanego oleju utrzymujac w ten sposób stala temperature powietrza suszacego w segmentach komory 4 maszyny powlekajacej co daje pozadany efekt.Zastrzezenie patentowe Uklad regulacji temperatury powietrza, zwlaszcza w komorach grzewczych maszyn powlekajacych, majacych rurociag wlotowy wprowadzony do segmentu komory i polaczony z nagrzewnica, z której jest wyprowadzony i polaczony z zaworem i z wylotowym rurociagiem, znamienny tym, ze w rurociagu wlotowym (1) czynnika grzewczego osadzony jest przetwornik temperatury (2) polaczony poprzez regulator (7) z zaworem (6) czynnika grzewczego, natomiast w komorze (4) z ogrzanym powietrzem umieszczony jest przetwornik (8) polaczony poprzez regulator (9) z regulatorem (7).Prac. Poligraf. UP PRL. Naklad 120 egz.Cena 100 zl PLThe subject of the invention is an air temperature control system, especially in the heating chambers of coating machines. It is used for the production of synthetic leathers and tarpaulins. The control systems used so far have a transducer embedded in the chamber segment and connected through a regulator with a valve. The disadvantage of such a system is the inability to maintain a constant temperature of the drying air, due to large fluctuations in the temperature of the liquid heating medium, for example oil. The aim of the invention is to eliminate these drawbacks. This aim was achieved thanks to the use of a cascade system consisting of a temperature transducer embedded in the heating medium inlet pipeline and connected via a regulator with the heating medium valve, while in the chamber with Heated air is placed in a transducer connected through a second regulator with the first regulator. The advantage of this invention is high sensitivity and keeping the temperature of the drying air constant with great accuracy, which results in the production of a high quality product with a small number of rejects. In the example of the embodiment in the drawing in the general diagram. In the inlet pipeline 1, which supplies hot oil, there is a temperature converter 2. The inlet pipeline 1 is connected to the heater 3, which is placed in the chamber segment 4. The outlet pipeline 5 is led from the other end of the heater 3, who It is equipped with a valve 6 outside the chamber 4. The temperature converter 2 is connected to the controller 7 and the valve 6. The second converter 8 is placed in the segments of the chamber 4 and connected to the second controller 9, which is connected to the controller 7 through which it acts on the valve 6. The operation of the system is based on the fact that hot oil is supplied through the inlet pipeline 1 to the heater 3, which is located in the chamber segment 1, and heats the air contained around the heater. Then the oil is drained through the valve 6 through the pipeline 5. The oil temperature is measured by the converter 2 in front of the heater 3. The signal generated in the converter 2 due to the appropriate oil temperature is supplied to the controller 7 which controls the valve 6 located on the outlet pipeline 5. The second converter 8 measures the temperature of the air circulating in the chamber 4 segments caused by the blower 10. The signal in the second transducer 8, caused by the air temperature, is fed to the second controller 9, which in turn sets the set point 116175 of the first controller 7 and influences valve 6 regulates the flow of heated oil, thus maintaining a constant temperature of the drying air in the chamber segments 4 of the coating machine, which gives the desired effect. Patent Disclaimer Air temperature regulation system, especially in the heating chambers of coating machines, which have an inlet pipeline inserted into the chamber segment and connected y with a heater from which it is led and connected with the valve and with the outlet pipeline, characterized in that a temperature converter (2) is embedded in the inlet pipeline (1) of the heating medium, connected via the regulator (7) with the valve (6) of the heating medium, while in in the heated air chamber (4) there is a transducer (8) connected via a regulator (9) with a regulator (7).
