Description

Technical field:

[0002] The utility model relates to a resin filtering mechanism, in particular to a resin filtering mechanism used at the discharging end of a resin reaction kettle. Background technology:

[0004] The Chinese patent "resin discharge filtering mechanism", publication number CN209580173U, comprises an outer tank body and a partition arranged inside the outer tank body, the partition is provided with at least two through holes, a filter bag is sleeved on the through holes, the bag mouth of the filter bag is turned over and attached to the surface of the partition, and an annular pressing piece is pressed on the periphery of the bag mouth and locked with the partition by screws.

[0005] Although the resin discharge filter mechanism has a simple structure and a reasonable design, which is conducive to filtering and improving the quality of the finished resin product, during use, since the resin is not discharged all at once, sometimes there is a large interval between two discharges, and when the ambient temperature is lowered, larger agglomerates or gel-like agglomerates will form in the pipeline between the reactor and the filter mechanism. These agglomerates are not easy to pass through when passing through the filter bag, resulting in blockage of the filter bag, inability to continue filtering, and affecting the discharge efficiency. At this time, the filter mechanism must be opened and the blocked filter bag or bags must be removed and replaced.

[0006] The current filtering mechanism cannot solve the problem of agglomerated filtering and the problem of slow efficiency in replacing filter bags. Summary of the invention:

[0008] In view of the above-mentioned problems, the purpose of the utility model is to provide a resin filtering mechanism, which has a reasonable design and is conducive to avoiding the problem of agglomeration and clogging of the filter bag.

[0009] The utility model is implemented by the following scheme:

[0010] The utility model resin filtering mechanism is characterized in that it comprises an outer tank body with a feed inlet and a discharge port and a support plate arranged in the outer tank body, a filter plate is connected above the support plate in parallel and at intervals, an annular ring for supporting the filter plate is arranged on the inner peripheral wall of the outer tank body, the feed inlet of the outer tank body is located above the filter plate, the discharge port of the outer tank body is located below the support plate, a plurality of through openings are arranged on the support plate, a filter bag is arranged directly below the through opening, the bag opening of the filter bag is turned over and attached to the lower surface of the through opening of the support plate, and an annular pressing piece locked with the support plate by screws is pressed on the periphery of the bag opening.

[0030] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0031] The resin filtering mechanism of the utility model comprises an outer tank body 3 with a feed port 1 and a discharge port 2 and a support plate 4 arranged in the outer tank body, a filter plate 5 is connected above the support plate 4 in parallel and at intervals (the filter plate 5 is densely covered with filter holes, and the aperture of the filter holes can be one-fifth to one-tenth of the diameter of the feed port 1), the outer tank body is a cylindrical tank, and its upper part has an upper opening, wherein the feed port 1 of the outer tank body is located above the filter plate and at the upper side of the outer tank body, and the discharge port 2 of the outer tank body is located below the support plate and at the lower part of the outer tank body.

[0032] The finished resin material enters the cavity above the filter plate 5 of the outer tank body from the feed port 1, passes through the filter holes on the filter plate 5 and then through the filter bag, enters the cavity below the support plate of the outer tank body, and is discharged from the discharge port 2.

[0033] The support plate is provided with a plurality of through openings 7, and a filter bag 8 is arranged opposite to the through openings below. The bag opening of the filter bag 8 is turned over and attached to the lower surface of the through opening of the support plate, and an annular pressing piece 9 is pressed on the periphery of the bag opening and is locked with the support plate by screws, and threaded holes for locking screws are provided on the support plate.

[0034] An annular ring 6 for supporting the filter plate 5 is provided on the inner peripheral wall of the outer tank body 3. The annular ring 6 is made integrally with the outer tank body 3, or is fixed by screws. The filter plate 5 is movably supported on the annular ring 6. The filter plate 5 and the support plate 4 can be separated from the annular ring 6 and the outer tank body 3 by pulling the handle 10 located on the filter plate 5 upward. When the filter bag needs to be replaced, the old assembly formed by the filter plate 5 and the support plate 4 is taken out and directly replaced with a new assembly with a new filter bag (the filter plate 5, the support plate 4 and the filter bag 8 have been pre-assembled), thereby shortening the time for replacing the filter bag and reducing the downtime of the production line.

[0035] After the support plate 4 and the filter plate 5 (the aforementioned old components) are removed from the outer tank body 3, the annular pressing plate 9 and the filter bag 8 can be removed by removing the screws, and then a new filter bag is replaced, and the annular pressing plate 9 is used to press the bag mouth of the opened filter bag onto the lower surface of the support plate.

[0036] In order to realize the integral fixed connection between the filter plate and the support plate, the filter plate 5 and the support plate 4 are connected by a plurality of connecting columns 11, and the two ends of the connecting column are provided with a first stud 12 of reduced diameter, the first stud 12 and the connecting column 11 are coaxially arranged, the two ends of the first stud pass through the through holes on the filter plate and the support plate respectively and are locked and fixed by nuts 13, and the diameter of the first stud is smaller than the diameter of the through hole; during installation, the two ends of the first stud pass through the through holes on the filter plate 5 and the support plate 4 respectively and are locked and fixed by nuts 13, so that the integral fixed connection between the filter plate and the support plate is realized, and the connecting column 11 and the first stud 12 do not need to be removed when the filter bag is usually disassembled. It is precisely because the connecting column 11 and the first stud 12 are not disassembled at ordinary times that the bag mouth of the filter bag 8 is opened and is attached to the lower surface of the support plate through-hole, rather than the upper surface of the support plate through-hole, and the annular pressing sheet 9 is also installed on the lower surface of the support plate through-hole, thereby facilitating the disassembly and assembly of the filter bag 8 and improving the disassembly and assembly efficiency of the filter bag.

[0037] If the bag opening of the filter bag 8 is turned over and is attached to the upper surface of the support plate opening, and the annular pressing plate 9 is installed on the upper surface of the support plate opening, then in order to avoid interference from the screws on the annular pressing plate 9, the filter plate and the support plate need to be disassembled, thereby increasing the process of disassembling and assembling the filter bag and affecting the efficiency. The above structure adopted in the present application can improve the efficiency of replacing the filter bag.

[0038] In order to achieve a better supporting effect, an annular groove 14 is provided on the upper surface of the annular ring, and an annular convex ring 15 is provided on the lower surface of the filter plate to match and position with the annular groove. Due to the cooperation between the annular convex ring 15 and the annular groove 14, the filter plate can be supported on the annular ring more stably. Since the feed port is located above the filter plate, the filter plate is subjected to pressure from top to bottom. Therefore, there is no need for a separate limiting mechanism to restrict upward detachment, and the filter plate, support plate and other components can be conveniently taken out by the handle.

[0039] In order to facilitate opening and closing of the outer tank body, an upper cover 16 is provided on the upper opening of the outer tank body 3, and a crank arm 16 is provided on the side of the outer tank body. The crank arm 16 includes a column 17 rotatably connected to the side of the outer tank body at the lower end and a cross bar 18 connected to the upper end of the column. A screw 19 is threadedly connected to the cross bar, and a manual wheel 20 is fixedly provided on the upper end of the screw. The lower end of the screw is hinged to the middle of the top surface of the upper cover, that is, the screw 19 can rotate relative to the upper cover 16, but cannot move axially. The lower end of the screw can be limited in its groove, and a buckle 21 is provided around the tank mouth of the outer tank body, and a buckle groove 22 cooperating with the buckle is provided on the upper cover.

[0040] The buckle 21 comprises a second stud 23 and a rotating nut 24 screwed on the second stud, the lower end of the second stud is swingably hinged on the upper opening side of the outer tank body, a plurality of groups of two protrusions 25 close to each other are provided on the periphery of the upper cover, and a buckle groove is formed between the two protrusions, a plurality of steel bars 27 are evenly and vertically fixed on the rotating nut, and a ring steel bar 26 is welded and fixed to the upper end of each steel bar.

[0041] When in use, each buckle 21 fastens the upper cover 16 so that the upper cover 16 is sealed and fixed to the outer tank body 3. After a certain period of use, the filter bag 8 needs to be replaced. The rotating nut 24 can be unscrewed by rotating the annular steel bar 26 so that the rotating nut 24 is no longer fastened to the upper cover, and the second stud 23 can swing around the hinged end, and then the manual wheel 20 is rotated to make the upper cover rise under the action of the screw 19. After rising a certain distance, the column 16 and the cross bar 18 are turned so that the upper cover is no longer directly above the outer tank body 3, and the above-mentioned components can be taken out or put in.

[0042] The resin filter mechanism of the utility model is provided with a filter plate as the primary filter, so that the clumped resin can be isolated above the filter plate to prevent it from entering the filter bag and clogging the filter bag. Although the clumped resin also exists above the filter plate of the filter mechanism, the filter plate has a large area and the clumped resin cannot block all the filter holes, so that normal filtering work can still be guaranteed. When the filter bag needs to be replaced, the assembly formed by the filter plate, the support plate and the filter bag can be taken out together and replaced with a new set of components, so that the efficiency of replacing the filter bag in the past can be improved.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
