As shown in fig. 3 and 4, a filtering device 7 is disposed in the rotary cylinder 4, and the filtering device 7 is used for filtering materials so as to separate unmelted materials. The filter device 7 comprises an annular rotary ring 71 and a number of filter plates 72.

As shown in fig. 3 and 4, the rotary ring 71 is rotatably disposed inside the rotary cylinder 4 and between the rotary cylinder 4 and the accommodating cylinder 42, the axis of the rotary ring 71 is collinear with the axis of the inner wall of the rotary cylinder 4, the outer wall of the rotary ring 71 is attached to the inner wall of the rotary cylinder 4, the inner wall of the rotary ring 71 is attached to the outer wall of the accommodating cylinder 42, and both ends of the rotary ring 71 are attached to the inner walls of both ends of the rotary cylinder 4. A plurality of sliding grooves 711 are circumferentially arranged on the inner wall of the rotating ring 71, and the sliding grooves 711 are communicated with the inner side and the outer side of the rotating ring 71. Through grooves 712 are formed in both sides of the rotating ring 71 near both ends of the rotating ring 71, and the through grooves 712 communicate one end of the inner wall of the sliding groove 711 with one end of the rotating ring 71.

In the present embodiment, the third driver 53 is a motor, and drives the rotation ring 71 to rotate counterclockwise through the driving gear 531 and the tooth groove 713.

As shown in fig. 3 and 6, the filter plates 72 are slidably disposed in the slide grooves 711, respectively, and one side of the filter plates 72 close to the accommodating cylinder 42 can be bonded to the outer wall of the accommodating cylinder 42, and one side of the filter plates 72 away from the accommodating cylinder 42 can be bonded to the inner wall of the rotor cylinder 4. When the rotating ring 71 rotates, the chute 711 can be driven to move.

As shown in fig. 3 and 4, a plurality of filter holes 721 are distributed in the filter plate 72, and the filter holes 721 are located near the front side of the filter plate 72 in the rotation direction of the rotary ring 71. When the liquid material enters the material transferring pipe 41 from the material transferring port 421, the liquid material needs to pass through the filtering holes 721 on the filter plate 72, and the filtering holes 721 can filter out the impurities in the liquid material and the unmelted solid material, so as to achieve the effect of filtering out the solid impurities in the liquid material. When the rotary ring 71 is rotated, the filter plate 72 between the transfer port 421 and the transfer pipe 41 can be replaced.

As shown in fig. 5-6, the inner walls of both ends of the rotary cylinder 4 are provided with guide grooves 43, and the guide grooves 43 are located between the outer wall of the accommodating cylinder 42 and the inner wall of the rotary cylinder 4. Guide rods 722 corresponding to the positions of the through grooves 712 are fixed to both ends of the filter plate 72, and the guide rods 722 pass through the through groove 712 on one side and extend into the guide grooves 43 on the other side. For pushing the guide rods 722 to move in the through grooves 712 by the guide grooves 43 when the rotary ring 71 rotates, thereby driving the filter plates 72 to move in the guide grooves 43 toward both ends of the guide grooves 43.

As shown in fig. 5 to 7, the guide groove 43 between the transfer port 421 and the transfer tube 41 is far away from the accommodating cylinder 42, and the guide groove 43 at the other position is close to the accommodating cylinder 42, so that when the filter plate 72 moves between the transfer port 421 and the transfer tube 41, the guide groove 43 pushes the filter plate 72 to the end of the slide groove 711 away from the accommodating cylinder 42, so that the filter plate 72 can be attached to the inner wall of the transfer tube 4, and when the filter plate 72 leaves between the transfer port 421 and the transfer tube 41, the guide groove 43 pushes the filter plate 72 to the end of the slide groove 711 close to the accommodating cylinder 42, so that the filter plate 72 can be attached to the outer wall of the accommodating cylinder 42.

As shown in fig. 6 and 7, a first scraper 422 is formed at an end of the rotation opening 421 near the rotation ring 71 for scraping off the material adhered to the inner side of the rotation ring 71.

As shown in fig. 4 and 7, a groove 423 is concavely formed at the top end of the outer wall of the accommodating tube 42, a pressing plate 424 is fixed outside the groove 423, the pressing plate 424 is made of an elastic material, and in this embodiment, the pressing plate 424 is made of beryllium copper. The pressing plate 424 is attached to the inner wall of the rotary ring 71, and presses the filter plate 72.

As shown in fig. 6 to 7, the upper end of the accommodating cylinder 42 is concavely formed with a scraping groove 425, one end of the pressing plate 424 is extended into the upper side of the scraping groove 425, and a second scraping plate 426 is provided at the side of the upper end of the scraping groove 425 away from the pressing plate 424 for scraping the inner side of the rotary ring 71. One end of the scraping groove 425 is communicated with the outer side of the material rotating cylinder 4, and a cover plate 427 is fixed at the end, so that the inside of the scraping groove 425 can be cleaned by removing the cover plate 427.

In the present embodiment, the third driver 53 drives the driving gear 531 to rotate, and the driving gear 531 drives the tooth grooves 713 to rotate the rotating ring 71 counterclockwise. The rotary ring 71 rotates and pushes the filter plates 72 together through the slide grooves 711.

When the filter plate 72 moves between the material transferring port 421 and the material transferring pipe 41, the filter plate 72 filters liquid materials on one hand, filters solid impurities in the liquid materials, and facilitates mixing and extrusion of the liquid materials in the material discharging pipe 2; on the other hand, the speed of the liquid material flowing into the material transferring port 421 is reduced, so that the liquid material can be accumulated in the accommodating cylinder 42 by a certain amount, and the stirring rod 33 is convenient for fully stirring the liquid material, so that the liquid material is uniformly mixed.

Since the guide groove 43 located between the transfer port 421 and the transfer pipe 41 is away from the accommodating cylinder 42, the guide groove 43 pushes the filter plate 72 to an end of the slide groove 711 away from the accommodating cylinder 42 when the filter plate 72 is moved between the transfer port 421 and the transfer pipe 41. At this time, a space exists between the side of the filter plate 72 adjacent to the accommodating cylinder 42 and the inner wall of the rotary ring 71, that is, the filter plate 72 forms a recess in the inner wall of the rotary ring 71, and the solid impurities filtered out by the filter holes 721 are filtered out and stored in the recess in the inner wall of the rotary ring 71.

When the rotary ring 71 rotates counterclockwise, the filter plate 72 between the transfer port 421 and the transfer pipe 41 is pushed, and moves counterclockwise between the transfer cylinder 4 and the accommodating cylinder 42. In this process, the inner wall of the upper end of the rotating pipe 41 will scrape the outer wall of the rotating ring 71 and the side of the filter plate 72 away from the accommodating cylinder 42, while the first scraping plate 422 scrapes the inner wall of the rotating ring 71, so as to avoid the liquid materials on both sides of the rotating ring 71 from being brought between the rotating cylinder 4 and the accommodating cylinder 42. The filter plate 72 is recessed in the inner wall of the rotary ring 71 to prevent solid impurities from being scraped off by the first scraper 422 and to allow the solid impurities and part of the residual liquid material to be carried between the rotary cylinder 4 and the accommodating cylinder 42 through the recess in the inner wall of the rotary ring 71. At the same time, the next filter plate 72 is moved between the transfer port 421 and the transfer tube 41 to continue the transfer filtration. The effect of continuously carrying out material conveying and filtering is achieved, the filter plate 72 which is blocked by the solid impurities and used for blocking the filter holes 721 is timely removed, the material conveying speed is prevented from being reduced, and the production speed is ensured.

After the filter plate 72 moves from between the transfer port 421 and the transfer pipe 41 to between the transfer cylinder 4 and the pressing plate 424, the filter plate 72 is first pushed to the end of the chute 711 near the accommodating cylinder 42 by the guide groove 43. In this process, on the one hand, the filter plates 72 are eliminated from forming depressions in the inner wall of the rotary ring 71, and depressions are formed in the outer wall of the rotary ring 71; on the other hand, the filter sheet 72 is brought into contact with the surface of the pressing plate 424. Solid impurities and residual liquid materials originally in the depressions of the inner wall of the rotating ring 71 are pressed by the pressing plate 424 due to the movement of the filter plate 72. The remaining liquid material flows into the recess of the outer wall of the rotating ring 71 due to the extrusion through the filtering holes 721; the solid impurities cannot pass through the filtering holes 721, so the solid impurities are left on one side of the filter plate 72 close to the accommodating cylinder 42, and the extruding plate 424 is elastically deformed through extrusion force and is recessed into the groove 423, so the solid impurities are avoided, and the filter plate 72 is prevented from being clamped. The effect of separating the collected solid impurities from the residual liquid materials is achieved.

In the above process, the residual liquid material is located in the recess of the outer wall of the rotating ring 71 due to the gravity of the residual liquid material and the friction of the inner wall of the rotating cylinder 4, and the rear side of the rotating direction of the rotating ring 71. Since the filter holes 721 are located near the front side of the filter plate 72 in the rotation direction of the rotating ring 71, the residual liquid material in the depressions of the outer wall of the rotating ring 71 does not contact the filter holes 721.

When the filter plate 72 moves to the upper side of the accommodating cylinder 42 and passes through the scraping groove 425, the second scraping plate 426 scrapes off the side of the filter plate 72 near the accommodating cylinder 42 and solid materials fall into the scraping groove 425 because the guide groove 43 pushes the filter plate 72 to the end of the sliding groove 711 near the accommodating cylinder 42. Since the residual liquid material in the recess of the outer wall of the rotating ring 71 does not contact the filter holes 721, the residual liquid material does not fall into the scraping groove 425. The effects of cleaning solid materials and reducing waste of liquid materials are achieved.

As shown in fig. 7, the inner wall of the rotary cylinder 4 at the rear side in the rotation direction of the rotary ring 71 is recessed with the escape groove 45 at one end of the rotary pipe 41.

When the filter plate 72 moves to the lower side of the accommodating cylinder 42, and is ready to enter between the transfer port 421 and the transfer pipe 41 again, the guide groove 43 drives the filter plate 72 to move to the end of the slide groove 711 away from the accommodating cylinder 42. At this time, by avoiding the groove 45, the liquid material is prevented from being pushed to the inside of the swivel 71.

In summary, through the continuous circulation of a plurality of filter plates 72, the effect that lets filter equipment 7 continuously filter out the solid impurity in the liquid material to automatic clearance and collection solid impurity reach the effect that filter plate 72 can recycle.

The solid impurities in the scratch groove 425 can be cleaned by removing the cover plate 427.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
