[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] See also Figure 1 A backwash melt filter includes a tank body 10, the tank body 10 includes a feed port and a discharge port, an end cover 11 is hinged on the top of the tank body 10, and the filter chamber inside the tank body 10 can be viewed by opening the end cover 11.

[0025] like Figure 2 and Figure 3 As shown, a fixing mechanism 20 is provided inside the filter chamber, and the fixing mechanism 20 includes a fixing ring 21 fixedly connected to the inside of the tank body 10, and the fixing ring 21 is provided with evenly distributed limiting grooves 22, and a cover plate 23 is provided on the fixing ring 21, and the number and position of limiting posts 24 corresponding to the limiting grooves 22 are fixedly installed on the cover plate 23, and the cover plate 23 is also provided with a mounting hole 26 for placing a filter rod 25, and a collar is fixedly installed above the filter rod 25. In this embodiment, the filter rod 25 equipped with the collar is first placed into the mounting hole 26, and then the filter rod 25 can be suspended on the cover plate 23 by the cooperation of the collar and the mounting hole 26. At this time, the cover plate 23 is placed in the interior of the tank body 10 as a whole, and is screwed into the fixing ring 21 in a manner corresponding to the limiting grooves 22 and the limiting posts 24, so that the cover plate 23 and the fixing ring 21 form a stable structure.

[0026] Further, such as Figure 3 As shown, symmetrically distributed handles 30 are fixedly installed on both sides of the cover plate 23, and the cover plate 23 can be easily taken away through the handles 30.

[0027] Furthermore, Figure 5 As shown, the limiting column 24 includes a fixing seat 241 fixedly connected to the cover plate 23, and an inserting column 242 connected to the limiting groove 22. A sliding groove is provided inside the fixing seat 241, and the inserting column 242 slides inside the sliding groove, and a reset spring is provided between the fixing seat 241 and the inserting column 242. In this embodiment, through the setting of the fixing seat 241 and the inserting column 242, when the inserting column 242 is inserted into the limiting groove 22, a relative movement will occur between the cover plate 23 and the fixing ring 21, so that during the filtering process, the cover plate 23 will form an up-and-down state due to the action of the impact force after the liquid enters the tank body 10, which can, on the one hand, buffer the impact force of the liquid just entering the tank body 10; on the other hand, for the filter rod in the up-and-down state, it can avoid the problem of excessive impurities adhering to the filter rod and thus clogging the filter rod.

[0028] Among them, the limiting groove 22 and the insertion column 242 are slidably connected, and there is a certain sliding resistance between the two. After the insertion column 242 is screwed into the limiting groove 22, due to the overall weight of the cover plate 23, the cover plate 23 will not rotate back (that is, the problem of the insertion column 242 rotating back and disengaging from the limiting groove 22 will not occur).

[0029] like Figure 4 As shown, a limit plate 40 is disposed above the cover plate 23, and a plurality of sleeve holes 41 corresponding to the size and position of the filter rods are opened on the limit plate 40. When in use, the filter rods are first installed through the above steps, and then the sleeve holes 41 are aligned with the filter rods after installation, and then the limit plate 40 is installed, so that all the filter rods can be installed and fixed.

[0030] Further, such as Figure 6 As shown, the limit plate 40 and the cover plate 23 can be fixed by bolts. After the position between the limit plate 40 and the cover plate 23 is fixed, the sleeve hole 41 will limit the sleeve ring on the filter rod, so that its position in the vertical direction is fixed, thereby ensuring the stability of the filter rod after installation.

[0031] The working principle of the utility model is as follows: when working, firstly, the filter rod 25 is placed into the mounting hole 26 on the cover plate 23, and then the limiting plate 40 is fixedly mounted on the cover plate 23 by bolt connection in a corresponding manner between the sleeve hole 41 and the sleeve ring, and then, by holding the handle 30, the entire cover plate 23 is placed into the fixing ring 21 provided inside the tank body 10, and by the presence of the limiting column 24 and the limiting groove 22, the position of the cover plate 23 and the fixing ring 21 can be fixed, thereby achieving a quick installation effect of the entire filter rod 25.

[0032] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
