Description
Technical field
The present invention relates to cross-linked polyolefin foaming furnace, particularly a kind of foaming furnace for crosslinked polypropylene.
Background technology
Existing crosslinking polyolefin foaming stove mainly contains two kinds of structures, a kind of be with vertical furnace be foaming section foaming furnace, another kind sets up horizontal stove before vertical furnace, horizontal stove mainly provides the preheating of master slice, after making the master slice of arrival vertical furnace have certain temperature, be conducive to foaming and guarantee foaming quality, vertical furnace is foaming section, is that main foam process completes station.Existing foaming furnace is all generally the foaming for alkene such as polyethylene, be different from polyethylene, polyacrylic crosslinked foaming has higher sensitiveness for temperature when preheating before foaming, foaming and the constant of blowing temperature, and this just has higher requirement to the structural design of foaming furnace
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of foaming furnace for crosslinked polypropylene, it can well control the temperature required of polypropylene expanded process, makes sheet material uniform in foaming, improves yield rate.
The technical solution adopted for the present invention to solve the technical problems is: a kind of foaming furnace for crosslinked polypropylene, comprise horizontal stove and vertical furnace, it is characterized in that, also comprise column support, horizontal stove base is provided with above column support, horizontal stove is arranged on horizontal stove base, vertical furnace is arranged on the right side of column support, draw in horizontal stove through draw-gear after master slice is unreeled by unwinding device, foam by vertical furnace, then rectify a deviation through Deviation rectifier, the cutting edge of cutting edge device, finally by the rolling of double coiler; Be provided with horizontal stove heating rod in described horizontal stove, before and after described vertical furnace, both sides are provided with expander, and the left and right sides is provided with heater.
Preferably, described horizontal stove is divided into the first preheating section, the second preheating section and the 3rd preheating section, three sections of cascade raising temperatures.
Preferably, described horizontal stove is made up of body of heater and bell, and horizontal stove outer wall is carbon steel sheet, and inwall is corrosion resistant plate, and be heat insulation layer between outer wall and inwall, furnace interior both sides are provided with conveyer belt bracket.
Preferably, described heater, by being arranged on the vertical furnace heating rod outside vertical furnace and the fan inside vertical furnace forms, being compared arranging of simple heating rod by this kind of mode of heating and can better be controlled blowing temperature in vertical furnace.
Good effect of the present invention: the foam pattern that the utility model adopts horizontal stove to be combined with vertical furnace, progressively preheating and corresponding structural design can be good at as polyacrylic foaming is ready the segmented of horizontal stove, and the mode that vertical furnace heating adopts heating rod to combine with fan, can be more prone to and control foaming zone temperature in vertical furnace easily, make crystalline p p sheet uniform in foaming, greatly improve its yield rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the foaming furnace for crosslinked polypropylene of the present invention;
Fig. 2 is the cross section structure schematic diagram of horizontal stove of the present invention.
Detailed description of the invention
