[0031] To make the above-mentioned objectives, features and advantages of this utility model more easily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0033] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0034] Example 1:
[0035] Please see Figure 1 - Figure 3 This is the first embodiment of the present utility model.
[0036] This embodiment provides a segmented spiral pulper filter assembly, including:
[0037] The cylinder 1, the drain hopper 2, and the rectangular groove 5; the drain hopper 2 is fixed on the circumferential surface of one end of the bottom side of the cylinder 1, and the rectangular groove 5 is symmetrically opened at the middle position on both sides of the drain hopper 2, and also includes:
[0038] The filter mechanism 3, the positioning mechanism 4, and the squeezing mechanism 6 are provided. The filter mechanism 3 is located inside the discharge hopper 2, the positioning mechanism 4 is located at one end of the discharge hopper 2, and the squeezing mechanism 6 is located inside the cylinder 1.
[0039] Specifically, the filtration mechanism 3 includes: a fixed plate 31, a take-up roller 32, a groove 33, a limiting roller 34, a filter screen 35, sieve holes 36, and a turntable 37. The fixed plate 31 is symmetrically fixed on both sides of the discharge hopper 2. The take-up roller 32 is rotatably installed on the inner side of the fixed plate 31. Sieve holes 36 are evenly opened on the circumferential surface of one end of the bottom side of the cylinder 1. The filter screen 35 is wound on the take-up roller 32, and one end of the filter screen 35 is fixedly connected to the circumferential surface of the take-up roller 32. The limiting roller 34 is symmetrically fixed on the inner side of the discharge hopper 2. The groove 33 is opened on the inner side of the discharge hopper 2. The filter screen 35 passes through the rectangular groove 5 and is installed on the inner side of the discharge hopper 2. The filter screen 35 is fitted on the limiting rollers 34 on both sides. The filter screen 35 is slidably installed on the inner side of the groove 33. One end of the take-up roller 32 passes through the fixed plate 31 and is fixed to the turntable 37.
[0040] Furthermore, through the structure of the take-up roller 32 and the filter screen 35, during the process, the filter screen 35 inside the drain hopper 2 can be moved to the cleaning area by rotating the take-up roller 32, and the filter screen 35 outside the drain hopper 2 can be moved to the inside of the drain hopper 2, so as to prevent the processing efficiency of the pulping machine from being affected when cleaning and maintaining the filter screen 35.
[0041] In use, the slurry produced by the pulping machine is conveyed to the inside of the discharge hopper 2 through the screen 36. Then, with the help of the filter screen 35, the slurry is filtered and then output from the bottom of the discharge hopper 2. During the filtration process, the turntable 37 can be rotated to drive the winding roller 32 to rotate, thereby moving the filter screen 35 inside the discharge hopper 2 from the rectangular groove 5. At this time, the impurities on its surface can be cleaned. The filter screen 35 on the other side of the winding roller 32 is moved to the inside of the discharge hopper 2 for filtration, thereby ensuring that the filtration efficiency and processing efficiency of the pulping machine will not decrease.
[0042] In summary, through the structure of the filter mechanism 3 and the structure of the winding roller 32 and the filter screen 35, during the pulping process, one side of the filter screen 35 can be moved out from the inside of the discharge hopper 2, and the other side of the filter screen 35 can be moved to the inside of the discharge hopper 2. This facilitates cleaning and maintenance while ensuring that the filtration efficiency of the pulping machine does not decrease, thereby improving the processing efficiency of the pulping machine.
[0043] Example 2:
[0044] Please see Figure 4 - Figure 5 This is the second embodiment of the present utility model.
[0045] Specifically, the positioning mechanism 4 includes: a slide rod 41, a plate 42, a boss 43, a slot 44, and a spring 45. The slide rod 41 is symmetrically fixed at one end of the drain hopper 2. The plate 42 is slidably mounted on the slide rod 41. The bosses 43 are symmetrically fixed at both ends of the plate 42. The slots 44 are evenly opened on the circumference of the turntable 37. The bosses 43 are fastened to the inner side of the slots 44. A spring 45 is fixedly connected between the drain hopper 2 and the inner center of the plate 42.
[0046] Furthermore, the structure of the flat plate 42 and the boss 43 can fix the position of the turntable 37, preventing the filter screen from shifting under force and affecting the filtration quality of the pulping machine.
[0047] Specifically, the slurry squeezing mechanism 6 includes: a rotating shaft 61, a spiral blade 62, a servo motor 63, and a feed inlet 64. The rotating shaft 61 is inserted inside the cylinder 1 and is rotatably connected to the cylinder 1. The spiral blade 62 is fixed on the circumferential surface of the rotating shaft 61 and slides against the inner surface of the cylinder 1. The servo motor 63 is fixed at one end of the cylinder 1, and the output end of the servo motor 63 passes through the cylinder 1 and is fixedly connected to the rotating shaft 61. The feed inlet 64 is provided on the circumferential surface of one end of the top side of the cylinder 1.
[0048] Furthermore, through the structure of the spiral blades 62, while conveying the material, it can also be squeezed at one end of the inner side of the cylinder 1 to separate the slurry for subsequent processing.
[0049] In use, material is added through the feed inlet 64, and the servo motor 63 is controlled to drive the output shaft 61 to rotate. With the cooperation of the spiral blades 62, the material is transported to one end of the inner side of the cylinder 1 and squeezed. At this time, the slurry is transported from the screen hole 36 at one end of the bottom of the cylinder 1 to the inside of the discharge hopper 2. When the filter screen needs to be replaced, the plate 42 can be pulled to slide on the slide rod 41, causing the boss 43 to be pulled out from the inside of the slot 44, thereby releasing the fixation of the two turntables 37. The turntables 37 are then rotated to remove the inner filter screen 35 for cleaning and maintenance. At this time, the plate 42 is released, and the spring 45 pulls the plate 42 back to its original position, causing the boss 43 to be reattached to the inside of the slot 44, fixing the position of the two turntables 37 and ensuring that the filter screen 35 can filter normally.
[0050] In summary, through the structure of the positioning mechanism 4 and the squeezing mechanism 6, and through the structure of the spring 45 and the boss 43, the rotation plate 37 can be released before and after the filter screen 35 is replaced, and the rotation plate 37 can be fixed again after the replacement is completed, so as to prevent the filter screen 35 from shifting due to force during use and affecting the filtration quality.
