Description

A kind of air pipe device easy to clean

Technical field

The utility model is related to the field of production lithium ion battery microporous barrier, and wet method barrier film is applied to more particularly, to one kind The air pipe device easy to clean of transverse drawing mill.

Background technology

As the lithium ion battery microporous barrier of one of lithium ion battery key component to the internal resistance of battery, energy density, follow Ring life-span and security have direct influence.Most lithium ion battery microporous barriers are to use polyolefine material for raw material, Use wet processing（Thermally induced phase separation）And dry process（Simple tension and biaxial tension）And electrostatic spinning process technology.Its In, there are the process of a cross directional stretch, its equipment transverse drawing mill used during producing microporous barrier using wet processing Have successively from front to back be respectively arranged with above and below preheating zone, drawing zone, shaping area and cooling zone, the inside in each area blowing and can The airduct of heating.Wet method oil film before transverse drawing mill is entered is to be dissolved in higher boiling, low volatilization at high temperature by polyolefin Property diluent after be cooled into sheet by die head, slab, then obtain by longitudinal stretching, wherein higher boiling, low volatilization Property diluent typically select white oil, so this wet method oil film enter transverse drawing mill after be easy in preheating zone and drawing zone White oil is dropped on the upper surface of airduct, these white oils are long-term on airduct to form greasy filth shape or dry grease after high temperature The greasy dirt of shape, these greasy dirts are run up to after certain degree has certain shadow to product, the homogeneity of airduct air-out, cleaning Ring, be mainly manifested in the following aspects：（1）The air outlet of some positions of airduct is gradually blocked, the blast of air outlet is caused not Uniformly；（2）These greasy dirts can cause the defects such as oil stain, impurity to film by wind to film；（3）It is extremely difficult during cleaning, May need periodically to shut down the greasy dirt on special cleaning airduct, consume substantial amounts of time and manpower, thus reduce production efficiency and Increase the cost of product.How the several aspects based on more than, rapid cleaning airduct or design a kind of air pipe device easy to clean and ask The direction made great efforts into art technology staff is inscribed.

Utility model content

The purpose of this utility model is that there is provided a kind of air pipe device easy to clean for the above-mentioned the deficiencies in the prior art of solution.

The utility model is achieved through the following technical solutions：

A kind of air pipe device easy to clean, including airduct body and airduct body upper surface lay and airduct body Upper surface shape identical aluminium sheet, airduct body is fixed with aluminium sheet by bolt and nut；In addition offered on aluminium sheet Aperture, the quantity and size of aperture is identical with the air outlet of airduct body upper surface.

Preferably, the material of the airduct body is stainless steel.

Further, the material of the airduct body is 304 stainless steels.

Preferably, the aluminium sheet is aluminium alloy sheet.

Further, the aluminium sheet is 5083 aluminium sheets.

Preferably, the thickness of the aluminium sheet is 1 ~ 3 mm.

Further, the thickness of the aluminium sheet is 2 mm.

Preferably, the quantity of the bolt and nut is 8 pairs.

Preferably, the aluminium sheet must be smooth, otherwise can not be well fixed on airduct body upper surface.

The beneficial effects of the utility model are：

In use, oil droplet can be dropped on aluminium sheet airduct, when the greasy dirt on aluminium sheet runs up to influence product, wind Stop transverse drawing mill when planned shut-down or maintenance during the homogeneity of tube body air-out and cool, then dismantling has greasy dirt Aluminium sheet, then change new aluminium sheet, this method is time-consuming very short and cost is relatively low, can wave if greasy dirt on cleaning airduct Take substantial amounts of time and manpower, and the surface of airduct can be damaged.Therefore the utility model device can save big for cleaning airduct The time of amount and manpower, so as to improve the production efficiency and reduction human cost of wet method barrier film.

Embodiment

To be best understood from the utility model, the utility model is further described with reference to embodiment and accompanying drawing, with Lower embodiment is only that the utility model is illustrated rather than it is limited.

As illustrated in fig. 1 and 2, a kind of air pipe device easy to clean, includes the airduct body 1 of 304 stainless steels, in airduct The upper surface of body 1 is equipped with the thickness of one piece and the aluminium sheet of 1 upper surface shape identical of airduct body, 5083 aluminium sheet 2,5083 For 2 mm, airduct body 1 is fixed with 5083 smooth aluminium sheets 2 by 8 pairs of bolt and nuts 3；In addition offered on aluminium sheet 2 Aperture 4, the quantity and size of aperture 4 is identical with the air outlet of the upper surface of airduct body 1.

Oil droplet can be dropped on aluminium sheet 2 the utility model device in use, when the greasy dirt on aluminium sheet 2 is run up to Soon when influence product, the homogeneity of the air-out of airduct body 1, stop transverse drawing mill when planned shut-down or maintenance and drop Temperature, then dismantling has the aluminium sheet 2 of greasy dirt, then changes new aluminium sheet 2, and this method is time-consuming very short and cost is relatively low, if The greasy dirt on airduct body is cleaned, substantial amounts of time and manpower can be wasted, and the surface of airduct body can be damaged.

Shown by a series of experiments, change the aluminium sheet 2 on an airduct body 1 and only need to take 0.5H and 3 life Employee is produced, and the oil stain cleaned on an airduct body 1 needs to take 3H and 3 Manufacturing Worker and 1 bottle of cleaning agent, and one There are at least 40 airducts in individual transverse drawing mill, therefore the utility model can save substantial amounts of time and manpower certainly, so that Improve the production efficiency and reduction human cost of wet method barrier film.

Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New scope is defined, on the premise of the utility model design spirit is not departed from, and those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall into the guarantor that claims of the present utility model are determined In the range of shield.
