Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings, so as to make the technical solution of the present invention easier to understand and grasp.

[0036] A wire mesh plastic melt filter such as figure 1 As shown, a box body 1 is included. The box body 1 includes a box shell 18 with an opening on one side and a box cover 19 covering the opening of the box shell 18 . A cavity is formed between the box shell 18 and the box cover 19 .

[0037] Such as figure 2 , image 3 As shown, a filter screen plate 2 is arranged in the cavity of the box body 1, and the filter screen plate 2 separates the cavity to form the feed chamber 3 on the side away from the box cover 19 and the discharge cavity 4 on the side close to the box cover 19 . A feed port 5 is provided on the side wall of the box shell 18 , and the end of the feed port 5 is bent toward the side of the filter screen plate 2 and comm...

Abstract

The invention provides a silk-screen-free plastic melt filter which comprises a hollow box body. A filter screen plate is connected into the box body in a rotating manner. The filter screen plate partitions an inner cavity of the box body into a feeding cavity and a discharging cavity. A feeding opening, an impurity discharging opening and a discharging opening are formed in the box body. The boxbody is provided with a rotating shaft. The rotating shaft is connected with the filter screen plate. A scraper is fixed into the feeding cavity. The scraper abuts against the filter screen plate andscrapes off impurities on the filter screen plate. Meanwhile, the scraper can block the scraped impurities and guide the scraped impurities to the impurity discharging opening. The rotating shaft is driven by drive parts like a motor and drives the filter screen plate to rotate. The impurities attached to the filter screen plate are scraped off by the scraper, and move to the impurity dischargingopening under guiding of the scraper. The scraper blocks the impurities scraped off, and thus the situation that the impurities pass by the scraper easily and flow back to a treated area is avoided. Moreover, the scraper is fixedly connected into the feeding cavity, the impurities scraped off will not rotate around the rotating shaft in the feeding cavity, and the impurities can be discharged outrapidly from the impurity discharging opening.

Description

technical field [0001] The invention relates to the technical field of non-wire mesh filters, in particular to a non-wire mesh plastic melt filter. Background technique [0002] At present, the Chinese patent with the notification number CN109822857A discloses a filter without wire mesh, including a box body and a filter component, a cavity is formed inside the box body, and the filter component includes a filter set inside the cavity. A filter plate, and the filter plate divides the cavity into a feed chamber and a discharge chamber, and the box body is provided with a feed port and a miscellaneous discharge port connected to the feed chamber, which communicate with the The discharge port of the discharge chamber, the miscellaneous removal component is arranged at the miscellaneous discharge port, the box body is rotatably connected with a rotating shaft, and one end of the rotating shaft extends into the feeding chamber and is connected with a A scraper, the scraper is pr...
