Abstract
The utility model discloses an anti-cropping rotary valve, which belongs to feeding devices of blow molding machines. The anti-cropping rotary valve comprises a housing, a rotor is arranged in the housing, and a baffle plate is arranged on the side wall of a feed inlet of the housing. The anti-cropping rotary valve has the roles of anti-cropping and closing, each blade of an impeller is in the shape of T and can play the closing role, the inclined baffle plate is increased at the upper part of the meshing side of the feed inlet and the impeller on the housing, a gap is arranged between the inclined baffle plate and the impeller, the inclined baffle plate can ensure that raw materials can not enter the meshing part, and the gap is arranged below the inclined baffle plate, thereby avoiding the anti-cropping rotary valve from cropping, avoiding the wire drawing phenomenon and further avoiding the environmental pollution.
Description
Technical field
The utility model belongs to PE film preparation machinery, is specifically related to a kind of anti-blank rotary valve that is used for blow moulding machine.
Background technology
Plastic sheeting is common a kind of plastic products, it can be by process productions such as rolling process, extrusion molding, blowings, wherein inflation film is that plastic raw materials is extruded into light wall pipe to raw materials melt by extruder, then while hot with compressed air with its inflation, behind cooling and shaping, promptly get film article.Polyethylene (PE) is with its excellent mechanical property and thermal property, is widely used in the film of making various uses such as commodity bag, elasticity wrapping film, agricultural with film etc.At present, in " the control PE pellet strength that distributes delivery system " and the blow moulding equipments such as " container PE balk cargo pumping devices ", when the PE pellet enters the malleation pipeline by negative-pressure pipeline, the problem that exists is the chopping of PE particle can be produced wire drawing, and wire drawing floats in the air, causes environmental pollution.
The utility model content
The technical problems to be solved in the utility model is that " the control PE pellet strength that distributes delivery system " and " container PE balk cargo pumping device " are produced contaminated environment in the polyethylene film process, a kind of anti-blank rotary valve is provided, be used in " the control PE pellet strength that distributes delivery system " and " the container PE balk cargo pumping device ", reduced the environmental pollution that wire drawing causes.
The technical solution of the utility model realizes with following method:
Anti-blank rotary valve comprises shell, is provided with rotor in the shell, and the charging aperture sidewall of shell is provided with baffle plate.
Epitrochanterian leaf cross-section is a T shape.
Be provided with the space between described baffle plate bottom and the blade excircle.
Space between described baffle plate bottom and the blade excircle is more than or equal to the PE particle diameter.
The utlity model has anti-blank and airtight effect: the blade shape of impeller is a T shape, can play airtight effect, charging aperture and impeller interlock upper lateral part have increased by a slanting baffle on the shell, between this swash plate and the impeller space is arranged, slanting baffle has guaranteed that raw material can not enter the interlock position, the slanting baffle below is gapped also to have guaranteed self to cut less than material, can not produce wire drawing and cause environmental pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic perspective view of analysing and observe of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, anti-blank rotary valve of the present utility model comprises shell 1, is fixed with shaft tail end lid 4 and spindle nose end cap 3 on shell 1 both sides, is provided with rotor 2 in the shell 1, and blade 5 cross sections on the rotor 2 are T shape.The top of blade 5 is wide, and the bottom is narrow.The upper end open of shell 1 is that charging aperture, lower ending opening are discharging opening.The charging aperture sidewall is provided with the slanting baffle 6 of anti-blank.Be provided with the space that is greater than or equal to the PE particle diameter between described baffle plate 6 bottoms and blade 5 excircles, such as 5mm, 6mm etc.
The utlity model has anti-blank and airtight effect: the blade shape of impeller is a T shape, can play airtight effect, charging aperture and impeller interlock upper lateral part have increased a swash plate on the shell, 5mm distance (PE particle diameter) is arranged between this swash plate and the impeller, and the withdrawal rate that the rotating speed of impeller forms during this valve work is greater than inlet amount about 1/3.Can guarantee the discontented impeller groove of raw material dress like this, can blank, swash plate has guaranteed that raw material can not enter the interlock position, the swash plate below has the 5mm gap also to guarantee self to cut less than material.The exhaust outlet 7 of opposite side can discharge the gases at high pressure in the leaf groove in advance, can not make the raw material splash.The utility model is used in " the control PE pellet strength that distributes delivery system " and " the container PE balk cargo pumping device ", main effect is entered from the top of preventing the blank rotary valve by the raw material of negative pressure transportation system, and be discharged into the malleation conveyance conduit from the bottom, when finishing raw material and entering the malleation pipeline, can and not produce wire drawing with the chopping of PE particle by negative-pressure pipeline.Because the wire drawing meeting floats in the air, cause environmental pollution.
Claims (4)
