DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] The orientations mentioned in this specification are based on the orientations of the stacked-disk multi-roller filtrate machine of the present invention during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0036] Embodiment 1

[0037] like Figure 1 , Figure 2 as well as Figure 3 As shown together, the stacked multi-roller filtrate machine includes a feed box 1, a stirring box 2 and a filter box 3 which are connected in sequence, and the feed box 1, the stirring box 2 and the filter box 3 are three boxes horizontally arranged side by side; the discharge port of the feed box 1 is connected to the feed port of the stirring box 2, and the discharge port of the stirring box 2 is connected to the feed port of the filter box 3.

[0038] The fluid to be filtered is pumped into the bottom of the feed box 1 through the pump body. The interior of the feed box 1 is connected to an overflow pipe 10. The overflow pipe 10 is a vertical pipe. The top end of the vertical pipe extends to the upper part of the feed box 1, and the bottom end of the vertical pipe extends to the outside of the feed box 1. When the feed box 1 is overfed, the material level of the fluid to be filtered reaches above the top of the vertical pipe, and the excess fluid to be filtered will flow out through the overflow port to avoid blockage of the fluid to be filtered in the feed box 1. The remaining fluid to be filtered enters the mixing box 2 through the outlet of the feed box 1.

[0039] The body of the mixing box 2 is divided into a loading chamber 20 and a mixing chamber 21 by a partition. The loading chamber 20 is connected to the lower part of the mixing chamber 21, and the mixing chamber 21 is equipped with a mixing blade 210 driven by a power component. The fluid to be filtered discharged through the discharge port of the feed box 1 enters the loading chamber 20, and then moves downward into the mixing chamber 21. The fluid to be filtered is stirred to a uniform state by the mixing blade 210, and then enters the filter box 3 through the outlet at the upper part of the mixing chamber 21.

[0040] A roller group 30 is rotatably installed in the filter box 3. The roller group 30 includes a plurality of corrugated rollers 32 rotatably connected to the filter box 3. The corrugated rollers 32 are horizontally arranged. The corrugated rollers 32 include a main shaft 320 and a plurality of roller discs 321 axially sleeved on the main shaft 320 in sequence. The main shaft 320 is driven to rotate by a driving assembly. A key is installed between the roller disc 321 and the main shaft 320 so that when the main shaft 320 rotates, the roller disc 321 rotates synchronously. The roller discs 321 of two adjacent corrugated rollers 32 are staggered, and gaps for the filtrate to pass through are formed at the staggered positions.

[0041] The roller group 30 is provided with two rows spaced apart from each other in the upper and lower parts, and a filter channel 31 is formed between the two rows of roller groups 30 and the side wall of the filter box 3. The filter channel 31 connects the feed port and the discharge port of the filter box 3, and the filter channel 31 extends obliquely upward in a curved manner along the direction from the feed port of the filter box 3 to the discharge port of the filter box 3.

[0042] The fluid to be filtered enters the filter channel 31 through the feed port of the filter box 3, and is then continuously transported forward by the roller group 30. During the transportation process, the filtrate is continuously discharged downward and introduced into the collection bin from the bottom outlet of the filter box 3. The fluid to be filtered after deliquescence is transported by the roller group 30 and discharged through the discharge port of the filter box 3.

[0043] During the whole process, the fluid to be filtered can be filtered continuously, and the filtration is efficient and stable.

[0044] Preferably, the roller disc 321 includes a sleeve 322 and a disc body 323 which are coaxially arranged in one piece, wherein the sleeve 322 is located at the inner ring of the roller disc 321, and the disc body 323 is located at the outer ring of the roller disc 321, and the axial length of the sleeve 322 is greater than the disc body 323, so that adjacent sleeves 322 are arranged close to each other and an annular gap is formed between adjacent disc bodies 323. Of two adjacent corrugated rollers 32, the disc body 323 of one corrugated roller 32 extends into the annular gap of the other corrugated roller 32.

[0045] A shaftless spiral blade 34 is provided between the two rows of roller groups 30. The shaftless spiral blade 34 is parallel to the main shaft 320. Both ends of the shaftless spiral blade 34 are rotatably connected to the filter box 3. A plurality of shaftless spiral blades 34 are arranged at intervals along the extension direction of the filter channel 31, and the rotation directions of two adjacent shaftless spiral blades 34 are opposite. During the conveying process of the fluid to be filtered in the filter channel 31, part of the fluid to be filtered in the middle layer is conveyed to one side by the shaftless spiral blade 34, and when passing through the next shaftless spiral blade 34, it is conveyed to the other side by the next shaftless spiral blade 34, thereby evenly distributing the fluid to be filtered in the middle layer, diversifying the conveying direction of the fluid to be filtered, and improving the filtering effect of the fluid to be filtered.

[0046] Embodiment 2

[0047] The difference between this embodiment and the first embodiment is that Figure 4 As shown, the corrugated roller 32 is a tapered roller 33, and the tapered directions of adjacent corrugated rollers 32 are opposite. The filtering gap formed by the two tapered rollers 33 is longer, and the multi-directional variation of the conveying of the fluid to be filtered is improved, thereby improving the filtering effect.

[0048] Embodiment 3

[0049] The difference between this embodiment and the first embodiment is that Figure 5 As shown, the main shaft 320 includes a first connecting shaft 35, and the roller disc 321 is connected to the first connecting shaft 35. The first connecting shaft 35 has plug holes at eccentric positions on the two shaft end faces, and the second connecting shaft 350 is inserted in the plug holes. The first connecting shaft 35 is parallel to the second connecting shaft 350, and the two second connecting shafts 350 are coaxially arranged. The second connecting shaft 350 is rotatably connected to the side wall of the filter box 3. The corrugated roller 32 is rotated eccentrically, which can not only convey the fluid to be filtered, but also deviate up and down, so that the fluid to be filtered can be continuously and periodically pushed in the vertical direction, forming a squeezing effect on the fluid to be filtered, thereby improving the filtering efficiency.

[0050] Embodiment 4

[0051] The difference between this embodiment and the first embodiment is that Figure 6 As shown, the filter box 3 includes a front side plate, a rear side plate, a left side plate and a right side plate, and the front side plate, the rear side plate, the left side plate, the right side plate, the top plate and the bottom plate form a box body of the filter box 3; the left side plate and the right side plate are both rotatably mounted with a first turntable 36 through a sealed bearing, and the two first turntables 36 are coaxially arranged, and a first driving mechanism for driving the two first turntables 36 to rotate synchronously and coaxially is installed outside the filter box 3, and the end of the main shaft 320 is rotatably connected to the first turntable 36.

[0052] The two first rotating disks 36 are driven to rotate synchronously by the first driving mechanism, thereby adjusting the position of the roller group 30, that is, rotating and adjusting the inclination angle of the filter channel 31, so as to meet the filtering needs of different types of fluids to be filtered, thereby achieving precise regulation.

[0053] Specifically, the higher the proportion of solid matter in the fluid to be filtered and the greater the viscosity of the solid matter, the more difficult it is to separate the filtrate, and therefore the larger the tilt angle required. By rationally adjusting the tilt angle, the filtering effect can be improved.

[0054] In this embodiment, the first driving mechanism includes an electric push rod 360, and a first gear 361 is coaxially fixed to the first turntable 36. The driving shaft of the electric push rod 360 is coaxially fixed to a rack 362, and the rack 362 is meshed with the first gear 361. The electric push rod 360 drives the rack 362 to translate, and under the transmission of the rack 362 and the first gear 361, the first turntable 36 is driven to rotate.

[0055] Furthermore, the front and rear side plates of the filter box 3 are both installed with an annular sleeve, and a third ball groove 39 is provided in the annular sleeve. The third ball groove 39 connects the inside and outside of the filter box 3. A ball seat 40 is fitted and sleeved in the third ball groove 39, so that the ball seat 40 can rotate in multiple directions relative to the annular sleeve. A feed pipeline 41 is fixedly connected to the ball seat 40. The feed pipeline 41 penetrates the table of the ball seat 40 along the radial direction of the ball seat 40, and connects the inside and outside of the feed pipeline 41 filter box 3. A guide roller 363 is installed on the first turntable 36. The guide roller 363 is horizontally arranged. The guide roller 363 rolls and presses against the top and bottom surfaces of the feed pipeline 41 respectively, so that the feed pipeline 41 is limited in the two guide rollers 363 and swings with the rotation of the first turntable 36.

[0056] When the first rotating disk 36 is rotated and adjusted, under the guidance of the guide roller 363, the material conveying pipeline 41 is synchronously swung and adjusted, so that the material conveying pipeline 41 is always connected to the filtering channel 31, which can accurately meet the rotation adjustment requirements of the first rotating disk 36.

[0057] Embodiment 5

[0058] The difference between this embodiment and the fourth embodiment is that Figures 7 to 12 As shown together, the two first rotating disks 36 are rotatably mounted with the second rotating disk 37 via sealed bearings, and a second driving mechanism is installed outside the filter box 3, and the second driving mechanism is used to drive the second rotating disk 37 to rotate reciprocatingly periodically.

[0059] There are multiple second rotating disks 37, and the multiple second rotating disks 37 are arranged in an interval along the extension direction of the filter channel 31, and the multiple second rotating disks 37 installed on the left plate and the multiple second rotating disks 37 installed on the right plate are staggered along the arrangement direction;

[0060] A third turntable 38 is rotatably mounted on the second turntable 37 via a sealed bearing. The axial direction of the third turntable 38 is parallel to the axial direction of the second turntable 37. A third driving mechanism is mounted on the second turntable 37 for driving the third turntable 38 to rotate reciprocatingly periodically.

[0061] In the same row of roller groups 30, two adjacent corrugated rollers 32 form a group, and each third turntable 38 is rotatably connected to a group of corrugated rollers 32. The two corrugated rollers 32 in the same group are symmetrically arranged around the center of the third turntable 38. A fourth driving mechanism is installed on the third turntable 38, and the fourth driving mechanism drives the two corrugated rollers 32 to rotate synchronously in the same direction.

[0062] This enables the following actions:

[0063] 1. The two corrugated rollers 32 of the same group can rotate in the same direction, so that the roller group 30 can continuously transport the fluid to be filtered;

[0064] 2. A group of corrugated rollers 32 rotates synchronously around the center of the third rotating disk 38 as the third rotating disk 38 rotates;

[0065] 3. While the third turntable 38 rotates, it will revolve around the center of the second turntable 37 as the second turntable 37 rotates, that is, it drives a group of corrugated rollers 32 to revolve around the center of the second turntable 37.

[0066] Under the rotation adjustment of the second turntable 37 and the third turntable 38, each group of corrugated rollers 32 can be adjusted to rotate and revolve, so that in two adjacent groups of corrugated rollers 32, two adjacent corrugated rollers 32 of different groups can always maintain a fixed gap for the filtrate to pass through, and the corrugated rollers 32 can move up and down periodically, so that the entire filter channel 31 peristaltically transports the fluid to be filtered, thereby improving the uniformity of the fluid to be filtered and enhancing the filtration effect. Compared with a fixed roller group structure, the length of the filter channel 31 can be greatly shortened, thereby achieving refined filtration regulation.

[0069] The first ball 328 allows the end of the main shaft 320 that is not directly connected to the filter box 3 to be supported on the inner wall of the filter box 3, thereby improving the structural stability; the second ball 330 rollingly supports the first ball 328, thereby reducing the rolling friction of the first ball 328 and reducing the friction energy consumption; the scraping blade 326 of the limiting ring 325 continuously scrapes impurities adhered to the outer surface of the first ball 328 to prevent impurities from entering the first ball groove 324, thereby maintaining stable structural performance.
