Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of efficient silk screen filter device of plastic extruder, mainly comprises the feeding sleeve 1, urceolus 2 and the waste material female connector 3 that sequentially connect.
The top of described feeding sleeve 1 is provided with the charging aperture 11 be connected with extruder, and the front side of feeding sleeve 1 is provided with the feed cavity 12 of each working chamber 21 in some connection urceolus 2.
Inner interval layout setting at least two working chambers 21 side by side of described urceolus 2, select two in the present embodiment, can be set as more in practice as required.All install a cylindrical shape in each working chamber 21 without silk screen filter mechanism 4, leave gap between each filter mechanism 4 and the working chamber corresponding to it 21 inwall and form discharging chamber 211, discharging chamber 211 communicates with the common feed opening 22 arranged in the middle part of urceolus 2.
Described filter mechanism 4 is by filter ruffle 41 and the inside and outside combination of support set 42 are formed excessively.Cross filter ruffle 41 is positioned at support set 42 inwall by several press strips 43, cross and uniformly on filter ruffle 41 be provided with filtering micropore 411, the uniform discharge opening 421 being provided with aperture and being greater than filtering micropore 411 on support set 42.At this, for effectively realizing the linking conducting of filtering micropore 411 and discharge opening 421, the inwall of described support set 42 is provided with multiple cannelure 422, and be provided with the Support Level 423 supporting filter ruffle 41 between adjacent annular groove 422, its structure as shown in Figure 2.
The inner chamber front end crossing filter ruffle 41 is connected with the feed cavity 12 of respective side in feeding sleeve 1, and the intracavity posterior end of filter ruffle 41 is communicated with the corresponding impurity chamber 31 in waste material female connector 3 excessively, and being provided with one in the inner chamber of mistake filter ruffle 41 can along the scraper 5 of its inwall movement.Described scraper 5 activity orientation is on a power transmission shaft 6, and whole scraper 5 can relatively have and certain moves axially gap 61 by power transmission shaft 6, and scraper 5 can be moved back and forth by relative filter ruffle 41 inwall of crossing under the drive of a power source 7 vertically by power transmission shaft 6.Described scraper 5 be provided with breach and form the impurity runner 51 in a connection impurity chamber, power transmission shaft 6 being provided with a gland 62 matched with scraper 5 simultaneously.
In described waste material female connector, the by-pass valve control 8 of a discharge is at regular time and quantity installed in the outlet 311 in impurity chamber 31.
At this, scraper 5 above in each filter mechanism 4, be separated with gland 62 when moving after it is synchronous with power transmission shaft 6 and the impurity runner 51 above scraper 5 is opened, and to move after continuation along with scraper 51 and extruding plastic carries out plastic filter, made the impurity on filter ruffle 41 inwall scrape and enter the front of scraper 5 through impurity runner 51 simultaneously.And when scraper 5 itself and gland 62 when synchronously moving forward with power transmission shaft 6 offset, the impurity runner 51 on scraper 5 is glanded 62 closedowns, and realize the charging of plastics along with the continuation reach of scraper 5, and the impurity in scraper 5 front is pushed in impurity chamber 31 simultaneously.
From the above, each scraper 5 carries out the filtration work of plastics when only moving after with power transmission shaft 6, therefore, for make filter of the present invention efficiency be effectively played, the action that each scraper 5 in the present invention moves axially with power transmission shaft 6 is not at work consistent, and remain that a part of scraper 5 moves forward and moves after another part scraper 5, such action is equipped with, filter can be made to carry out continuously all the time, and plastic filter operates, and can promote the operating efficiency of filter at double.
To sum up, the filter mechanism 4 that the present invention utilized filter ruffle 41 and support set 42 to combine formation replaces silk screen filter mechanism, adding man-hour, the plastics being less than filter ruffle 41 inwall filtering micropore 411 diameter pass through, and the discharge opening 421 on support set 42 enters discharging chamber 211, and by common feed opening 22 discharging of urceolus 2 bottom, and the impurity being greater than filtering micropore 411 was stayed in the inner chamber of filter ruffle 41, and by the mobile mating reaction of gland 62 and scraper 5, impurity is expressed in impurity chamber 31 by by-pass valve control 8 discharge at regular time and quantity.
To sum up, the continuous circulation production that can realize plastic filter without silk screen filter device of the present invention's design, not draping in whole production process, does not burn net, and impurity is discharged automatically, has that operating efficiency is high, labour intensity is low, the feature of production environmental protection low-carbon (LC).
The above, it is only better embodiment of the present invention, not any pro forma restriction is done to the present invention, every according to know-why of the present invention to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solution of the present invention.
