Abstract
The utility model discloses a continuous filter provided with distribution screw rods and used for melt purification of plastic extrusion system. The continuous filter comprises a machine body, wherein, a feed opening and a discharge opening are formed on the machine body; through melt channels are formed between the feed opening and the discharge opening; filter sleeves are arranged in the melt channels in the machine body; each filter sleeve is provided with a plurality of tapered filter holes; the hole diameter at the inflow end of the filter hole is smaller than that at the outflow end of the filter hole; the screw rods are arranged in the middles of the filter sleeves; and taking the center of the feed opening as a reference, two segments of screw threads extending in opposite directions are arranged at the upper part and the lower part of the surface of each screw rod. The novel structure with the distribution screw rods and the design of an automatic impurity cleaning and discharging system ensure that the continuous filter can operate for a long time without needing manual impurity cleaning.
Description
Technical field
The utility model relates to a kind of plastics that apply to and extrudes the cleaning molten filter in the production, is meant that specifically the band that is used for purifying fusant of plastic extrusion system distributes the filter of screw rod.
Background technology
Extrude in the field in the production of plastic plate, sheet, film, filter is the corollary equipment that is coupled between extruder and the die head, and the filter mesh through filter interior filters the feed end melting media and promotes plasticizing once more, to satisfy the requirement of article of manufacture.
Existing filter all has screen pack to come impurity screening usually; When if this type of filter is used to produce the just impure a lot of the sort of raw material production of messy raw material; Because filter area is limited; Therefore impurity is piled up in filter screen soon, produces and promptly need not change filter screen for a long time, brings a lot of inconvenience to production.
The utility model content
The purpose of the utility model is to be provided for purifying fusant of plastic extrusion system; Be applicable to the special filter that those more types of feedstock of impurity are produced, its novel band distributes screw-rod structure, the design of dirty material automated cleaning discharge system can guarantee the long-time running of equipment and does not need manual work to remove to clear up impurity.
Above-mentioned purpose realizes through following technical scheme:
The band that is used for purifying fusant of plastic extrusion system distributes the continuous filter of screw rod; Include body; Wherein body is provided with charging aperture and discharging opening, is provided with the melt canal of perforation between the charging and discharging mouth, it is characterized in that: cross filter ruffle and be built in the melt canal in the body; Filter cover and be provided with several filtering holes, the inflow stomidium mouth diameter of filtering holes is less than the outflow end orifice diameter; In the middle of crossing filter ruffle screw rod is set, screw surface is a benchmark with the charging aperture center, and two parts are two sections screw thread settings moving towards opposite up and down.
Described filtration puts densely covered being arranged on of filtering holes and filters the side sections of jacket wall face towards discharging opening.
It is little that described filtering holes melt flows into stomidium mouth diameter, diameter range 0.3 mm ~ 1mm, and melt outflow stomidium mouth diameter is big, diameter range 1 mm ~ 3mm; Each filtering holes spacing 4 mm ~ 10mm.
Filter ruffle excessively and screw rod on the described body are provided with two groups.
Its endoporus of described sealing shroud is provided with and the reverse screw thread of axle rotation, number of starts 2-4 head.
Have discharging channel on the described body, discharging channel connected the melt canal at filter ruffle two-port place and the discharge gate on the body.
Be connected with the discharge control device on the described discharging channel, under the inner impurity accumulation of discharging channel certain pressure, the start-up control device is opened discharge gate impurity is got rid of outside the body, realizes not shutting down automatic discharge.
When melt after the body charging aperture flows into; Flow to filter ruffle, the bulk impurity in the melt is filtered the inboard that the hole was blocked in filter ruffle, and clean melt then passes through filtering holes smoothly; Filter the back through filter ruffle again and flow into tapping channel, accomplish the melt contaminant filter to discharging opening.Screw rod is driven by reduction box and rotates; Rotating the drive melt through screw rod flows in crossing filter ruffle; And screw rod spiral shell rib can be scraped the impurity that filters out near the discharge gate of two ends, gathers to open discharge gate behind the certain hour impurity is discharged body, realizes not shutting down automated cleaning.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1,2,3,4, shown in 5; The band that is used for purifying fusant of plastic extrusion system distributes the continuous filter of screw rod; Filter is made up of discharging rebound 1, body 2, mistake filter ruffle 3, bearing 4, seal cover board 5, sealing thread cover 6, screw rod 7, gear 8, adpting flange 9 and reduction box 10; Wherein body 2 is provided with charging aperture 21 and discharging opening 22, is provided with the melt canal 23 of perforation between the charging and discharging mouth.In the present embodiment; Melt canal 23 in the body is divided into two; The filter ruffle 3 of crossing on the body is provided with two groups with screw rod 7, crosses filter ruffle 3 and is built in the melt canal 23 in the body, crosses filter ruffle 3 and is provided with several filtering holes 31; Filtering holes 31 is arranged on filters the side sections that jacket wall faces discharging opening, and the inflow stomidium mouth diameter of filtering holes 31 is less than the outflow end orifice diameter.Wherein filtering holes 31 melts inflow stomidium mouth d1 diameter is little, diameter range 0.3 mm ~ 1mm, and melt outflow stomidium mouth d2 diameter is big, diameter range 1 mm ~ 3mm; Each filtering holes 31 spacings 4 mm ~ 10mm.
In the middle of crossing filter ruffle 3 screw rod 7 is set, screw rod 7 surfaces are benchmark with charging aperture 21 centers, screw rod 7 about two parts be two sections screw thread settings moving towards opposite, it is opposite with the motor direction of rotation that motor input screw thread moves towards.If any many screw arrangement, to move towards setting principle be after screw rod 7 rotates to screw thread on its screw rod 7, in the screw channel melt along in the mind-set two ends flow.Wherein sealing thread cover 6 its endoporus are provided with and the reverse screw thread of axle rotation, number of starts 2-4 head.
Like Fig. 3, shown in 4, have discharging channel 24 on the body 2, discharging channel 24 connected the melt canal 23 at filter ruffle two-port place and the discharge gate 25 on the body.Be connected with discharge control device 26 on the discharging channel 24, under discharging channel 24 inner impurity accumulation certain pressures, start-up control device 26 is opened discharge gate 25 impurity is got rid of outside the body, realizes not shutting down automatic discharge.
