Description
Technical field
The utility model relates to the technical field of segmentation heat-proof device, particularly relates to a kind of for the heat-proof device between the longitudinal cold stretch section of lithium battery diaphragm production line, longitudinal hot-stretch section and heat-setting section.
Background technology
Dry method simple tension is prepared microporous polypropylene membrane and has been developed more than 40 year, and complex process, control precision are high, the microporous barrier even aperture distribution of production.Longitudinal stretching section is the critical stage forming micropore, and its technological temperature is very large on pore-forming impact, so narrower temperature fluctuation, more accurate technological temperature is the key forming microporous barrier.
But, temperature between longitudinal cold stretch section in existing lithium battery diaphragm production line, longitudinal hot-stretch section and heat-setting section is very unstable, the temperature of longitudinal cold stretch section is easily subject to the impact of longitudinal hot-stretch section and heat-setting section high temperature, and then have impact on the stable of microporous polypropylene membrane properties of product.
Summary of the invention
The technical problems to be solved in the utility model is: the utility model provides a kind of heat-proof device for lithium battery diaphragm production line, the temperature overcome between the longitudinal cold stretch section in prior art in lithium battery diaphragm production line, longitudinal hot-stretch section and heat-setting section is unstable, and the temperature of longitudinal cold stretch section is easily subject to the problem of longitudinal hot-stretch section and heat-setting section temperatures involved.
The utility model solves the technical scheme that its technical problem adopts: a kind of heat-proof device for lithium battery diaphragm production line, comprise the overall heat shield covered on lithium battery diaphragm production line, four pieces of thermal baffles are provided with in described overall heat shield, overall heat shield is partitioned into three sections of heat shields by four pieces of described thermal baffles, they are respectively first paragraph heat shield, second segment heat shield and the 3rd section of heat shield, described first paragraph heat shield, second segment heat shield and the 3rd section of heat shield correspond respectively to the longitudinal cold stretch section in lithium battery diaphragm production line, longitudinal hot-stretch section and heat-setting section, the upper surface of first paragraph heat shield is evenly provided with multiple ventilating fan, overall heat shield and four pieces of thermal baffles are by double thermal insulation glass and aluminum alloy frame composition.
In order to the impact making the temperature of longitudinal cold stretch section not be subject to longitudinal hot-stretch section and heat-setting section high temperature, therefore the intensity of draft of described ventilating fan is adjustable.
Conveniently staff observes, therefore described double thermal insulation glass is transparent.
Conveniently staff enters, therefore described overall heat shield and four pieces of thermal baffles are equipped with sliding door.
The beneficial effects of the utility model are: a kind of heat-proof device for lithium battery diaphragm production line of the present utility model, by the method adopting segmentation heat insulation, make the longitudinal cold stretch section in lithium battery diaphragm production line, temperature stabilization between longitudinal hot-stretch section and heat-setting section, control within rational fluctuation range by the temperature between three, and by arranging the adjustable ventilating fan of multiple intensity of draft above longitudinal cold stretch section, the temperature of longitudinal cold stretch section is made not to be subject to the impact of longitudinal hot-stretch section and heat-setting section high temperature, and then ensure the stable of microporous polypropylene membrane properties of product, adopt transparent heat insulation double glazing to be applied on lithium battery production line, maintenance temperature constant while and facilitate staff to observe, the sliding door that heat-proof device is provided with facilitates staff to enter, and can not impact production.
