Zusammenfassung: | The invention relates to a process for carrying out the thermal cycle of a press for vulcanizing a rubber mat used for conveyor belts and to an installation for the application thereof. The process for carrying out a thermal cycle of a vulcanizing press comprises a stage of heating the pans of the vulcanization press to a temperature of 160A C, for 6 ... 10 minutes, followed by a stage of maintaining a temperature of 160 ... 140A C for 10 ... 15 minutes, in the vulcanization press pans, a stage of cooling with cold water for lowering the temperature of the vulcanization press pans to a value of 120 ... 110A C further comprising a stage of recirculating the demineralized mixture which is formed of cold water and hot water, in a 1 : 10 ratio, said mixture being reintroduced directly into the boiler for heating the water or into the generator. The installation for the application of the process, which comprises a hor water supply pipe connected to a group of recirculating pumps, being in connection with the vulcanization press pans, a discharge pipe being connected to the press pans, between the two pipes there being mounted a connecting pipe equipped with a mixer provided for injecting cold water into hot water, achieves a closed cycle consisting of the hot water supply pipe (1), the group of recirculating pumps (A), the pipe (17), the pans (18) of the vulcanization press, the return pipe (19), the front pipe (23), a cock (24) in open position, an injection mixer (26), the rear pipe (25) and a three-way cock (4).
Invenţia se referă la un procedeu pentru realizarea unui ciclu termic al unei prese de vulcanizare a unui covor din cauciuc, ce este utilizat la benzile transportoare, şi la o instalaţie pentru aplicarea acestuia. Procedeul pentru realizarea unui ciclu termic al unei prese de vulcanizat cuprinde o fază de încălzire a platanelor presei de vulcanizat la o temperatură de 160°C, într-un interval de 6...10 min, urmată de o fază de menţinere a unei temperaturi de 160...140°C, timp de 10...15 min, în platanele presei de vulcanizat, o fază de răcire cu apă rece, pentru reducerea temperaturii platanelor presei de vulcanizat la o valoare de 120...110°C, mai cuprinde o fază de recirculare a amestecului demineralizat, care este format din apă rece şi apă fierbinte, într-un raport de 1:10, amestec ce este reintrodus direct în cazanul de încălzire a apei sau în generator. Instalaţia de aplicare a procedeului care cuprinde o conductă de alimentare cu apă fierbinte |
