Description
Technical field
The utility model relates to the processing of rubber for tire, specifically the 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 ℃ above, be up to 170 ℃, then require to be down to below 45 ℃ 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 to be all with by the sensible heat variation (temperature rising) of medium (water or air) heat becoming popular on sheet rubber, the efficiency of lowering the temperature is comparatively speaking very low, (environment temperature reach 35 ℃ above time) 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. ℃, so cooling rate is slow, air quantity demand is large, causes that large, the outer row of power consumption is large with the air quantity of peculiar smell, 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 minute 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 ℃ 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 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.
Utility model content
The object of the utility model utility model is to provide the cooling device of hot sheet rubber in a kind of rubber for tire process.This device must adapt to multiple hot sheet rubber specification, and energy fast cooling, guarantees to produce and do not stop continuously.
To achieve these goals, hot sheet rubber heat sink of the present utility model, is provided for the spraying system that thermotropism sheet rubber is sprayed.

Comprise >=1 independent atomizer passgae of spraying system.Generally routinely, consider heat exchange amount and place size, and the situation of control operation system, spraying system comprises 2～8 independent atomizer passgaes, each independent atomizer passgae is connected with more than one control valve.
Control valve can be selected pressure-regulating valve, magnetic valve or hand-operated valve.
In order to realize two-sided spraying, obtain better cooling-down effect, the independent atomizer passgae of spraying in opposite directions can be set in spraying system of the present utility model.
Why a plurality of independently atomizer passgaes are set, and are the size and shapes of considering according to hot sheet rubber product, and thickness, sometimes do not need atomizer passgaes all in the spraying system of a heat sink all to open spraying.Independent atomizer passgae, under the control of control operation system, can carry out respectively work independently.The spraying system of the independent atomizer passgae of spraying in opposite directions is for example set, when not needing two-sided spraying, only need to allows above or independent atomizer passgae work below.
The utility model is in order to obtain better cooling-down effect, and in spraying system, each independent atomizer passgae arranges 1～10 row's nozzle, is preferably 2～6 row's nozzles, and row's spacing is 100～600mm, and row's inner nozzle spacing is 80～300mm.Nozzle is 80～500mm from the distance of the hot sheet rubber of need cooling, is preferably 350～450mm, more preferably 380～420mm.
Mist cooling, utilizes water smoke rapid evaporation to take away heat exactly.Water smoke evaporation is exactly the vaporization of water, and due to the geometry of water smoke ball, the specific area of 10 microns of water droplets is 10 times of 100 microns of water droplets.Be accompanied by atomization, the surface area of hundreds of millions water droplets is very large, thereby can rapid evaporation vaporization absorption amount of heat.General, make water evaporate needed heat at its boiling point and be five times in the water gagings such as handle and be heated to 100 degrees Celsius of needed heats from one degree Celsius.Evaporate rapidly when forming the little water droplet of water atomization and hot material surface collision, thereby effectively from hot material, remove heat energy.The water smoke particle diameter that spraying is formed is 1～100 micron.Under preferred situation, water smoke average grain diameter is less than or equal to 30 microns, is preferably less than or equal to 10 microns, more preferably, is less than or equal to 5 microns.If water droplet is too large, for example 100 microns or larger, during the surface collision of water droplet and hot material, can not evaporate fast enough, on the surface of hot material, form liquid film, or keep floating on the surface of hot material, and the overlong time that liquid film leaves from hot material surface boiling, cooling effect has slowed down.Good cooling in order to realize, water droplet needs sufficiently little, and to have enough little quality for rapid evaporation, and water droplet is guided to enough speed on the surface of hot material, to realize effective collision.Water smoke particle diameter is determined by factors such as nozzle bore, nozzle form and hydraulic pressure.Force (forcing) pump in the utility model device can increase hydraulic pressure, makes water smoke particle diameter reach requirement.
Carry hot TR thin rubber sheet can select conventional conveyer belt, preferably adopt with the metal conveyor belt of grid or with plastic conveyor belt or metal power-driven roller or the sheet type roller etc. of grid, hot rubber carried continuously.
In rubber tyre process, adaptation efficiently, the operation of mist cooling has much fast: type glue extruding production line, the inner liner pressed production lines etc. such as the cooling production line of film in banburying workshop, the compound pressed production line of tyre surface of semi-finished product beamhouse, sidewall.
Device of the present utility model can be applied to the fast cooling of various hot materials and cooling, as the refrigerated product that needs on the manufacture of rubber, plastics, metal, glass or other materials, process for producing line.Can reduce within a short period of time and need refrigerated product temperature, reduce water consumption and electric quantity consumption, substantially realize non-wastewater discharge.
