Description
Technical field
The utility model relates to the processing of rubber for tire, specifically the quick cooling device of hot sheet rubber in process.
Background technology
In the process of rubber for tire, have many operations all need by elastomeric compound be heated to 100 DEG C above, be up to 170 DEG C, then require to be down to below 45 DEG C in 30-60 minute.And all work continuously, be that per tour suspends about 30 minutes substantially.Current cooling method mainly contains: natural air cooled, water spray+immersion+blowing, the cooling etc. indirectly of air-cooled, the circulating water metal roller of air-conditioning.
These above-mentioned cooling methods are all to change (temperature rising) by the sensible heat of medium (water or air) to be with the heat becoming popular on sheet rubber, the efficiency of lowering the temperature is comparatively speaking very low, (when environment temperature reaches more than 35 DEG C) particularly during the broiling summer, force cooling medium (wind, water etc.) flow greatly to increase, required cooling place also must increase.And along with the increase of production efficiency, the required rate-of flow of the lowering the temperature place that must increase, lower the temperature also must increase, the cost of cooling and energy consumption are also increasing.Its major defect is exactly: the main variations in temperature by medium wind of cooling is taken away heat, it is the sensible heat cooling that utilizes medium, the specific heat capacity of air only has 1.005kJ/kg. DEG C, so cooling rate is slow, air quantity demand is large, causes that the air quantity of large, the outer row of power consumption with peculiar smell is large, factory building takes up an area large etc. shortcoming.
In the occasion that adopts shower water+immersion tank+blowing associating falling temperature technique, 2500 of output every days of tyre surface pressed production line, per hourly extrude hot sheet rubber 2500kg.For continuous production, 120 meters of long tanks (can point multilayer multistage in order to reduce place tank), the water of the immersion tyre surface of about 150 tons needs 25.3 m
3/ h(25 DEG C of water at low temperature) carry out heat exchange, to take away the heat in tread-rubber sheet.Along with the sweltering heat of weather, the raising of production efficiency, the internal circulating load that must must extend tank, increasing water at low temperature meets technological requirement.Simultaneously the water in tank just needs to change after using approximately continuously January, and due to the rubber of this water long period of soaking high temperature, some organic compounds in rubber are useful goes out to have polluted water, and this water can not continue to use, regularly emission treatment.
Tank soaks cooling and has a following shortcoming: the main variations in temperature by WATER AS FLOW MEDIUM of cooling is taken away heat, and cooling rate is slow, and water demand is large, cause power consumption large, need regular sewage effluent, factory building to take up an area large etc. shortcoming.
In order to adapt to the development of rubber for tire processing industry, the cool-down method of energy-conserving and environment-protective and technology are the directions of development.So the research of this respect, test, innovation must go out new results.
