Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, and in particular to a roller and a solid-liquid separator. Background Technology

[0002] With increasingly stringent environmental protection requirements, the treatment of livestock and poultry manure has become a hot topic of great concern to the whole society. To achieve the harmless and resource-oriented treatment of livestock and poultry manure, advanced fermentation processes such as aerobic composting and anaerobic fermentation are needed to treat the manure. Before or after anaerobic treatment, the water in the diluted manure needs to be separated.

[0003] Chinese Patent CN208591606U discloses a device for solid-liquid separation of fecal wastewater. The device includes a main body with a cylindrical screen structure horizontally rotating on it. A drive device is located on the main body below the screen structure to rotate it. The screen structure consists of a left support plate, a right support plate, and a screen connected between the left and right support plates. Ribs protruding towards the screen's axis are spirally wound around the inner wall of the screen. A collection box for collecting fecal wastewater is located directly below the screen and is fixed to the main body. An inlet for livestock excrement is located on the left support plate, and an outlet for fecal residue is located on the right support plate. A wastewater outflow pipe is connected to the bottom of the collection box. This device not only provides good separation and high efficiency but also allows for real-time monitoring of the screen's dirtiness and blockage.

Detailed Implementation

[0016] Example 1 like Figure 1 As shown, the roller proposed in this embodiment includes a machine body 1, a roller body 2 is rotatably arranged inside the machine body 1, mounting rings 3 with annular guide rails are arranged at both ends of the roller body 2, and multiple first reinforcing ribs 4 and multiple second reinforcing ribs 5 arranged in annular array are arranged on the roller body 2.

[0017] A baffle 7 is provided on the machine body 1, a retaining ring 6 is provided on the roller body 2, a fixing block 8 is provided on the baffle 7, and a scraper 9 that is slidably connected to the retaining ring 6 is provided on the fixing block 8.

[0018] In this embodiment, the first reinforcing rib 4 and the second reinforcing rib 5 are used to improve the structural strength of the thin roller body 2 and avoid serious deformation. The spiral guide plate inside the roller body 2 is used to guide and transport the material, prolonging the time the material spends inside the roller body 2, thereby ensuring the separation quality. The machine body 1 is provided with a support device to drive the roller body 2 to rotate. This support device is not labeled. This support device adopts relevant technical system equipment that has been established and applied in the field of solid-liquid separators. Generally, a drive device drives the roller to rotate. The annular guide rail on the mounting ring 3 drives the roller body 2 to rotate relatively slowly, thereby performing solid-liquid separation processing on the material inside the roller body 2. The baffle 7 and the baffle ring 6 can block water near the bottom of the inclined roller body 2. The fixing block 8 and the scraper 9 can remove particles and water from the baffle ring 6, so that they are discharged and collected through the drain pipe in the middle. The feces will be discharged and collected from the bottom of the roller body 2.

[0019] It should be noted that the machine body 1 is equipped with a cover (not shown) with an observation window, which serves to protect and isolate the parts.

[0020] Example 2 like Figure 1 - Figure 3 As shown, this embodiment of a solid-liquid separator includes a rotating rod 10 and a roller as described in the previous embodiment. The rotating rod 10 is provided with brush bristles 11, and first connecting blocks 12 are provided at both ends of the rotating rod 10. A rotating shaft 13 is rotatably connected to the machine body 1, and a second connecting block 14 is provided at the end of the rotating shaft 13. Mounting assemblies are provided on the first connecting blocks 12 and the second connecting blocks 14. The mounting assemblies include a pressing block 16 slidably connected to the first connecting block 12, two first wedges 17 symmetrically distributed on the pressing block 16, and a second wedge slidably connected to the first wedges 17. 18. A partition 19 disposed inside the first connecting block 12; a spring 20 disposed on the partition 19 and the second wedge 18; a connecting rod 22 disposed on the second wedge 18; a locking block 23 disposed on the connecting rod 22; a pressure plate 25 fitted onto the first connecting block 12 and the second connecting block 14; four insert rods 26 disposed on the pressure plate 25; and nuts 27 threaded onto the insert rods 26; the second wedge 18 is slidably disposed inside the first connecting block 12; and the second connecting block 14 is provided with a mating groove 28 for the locking block 23 and the connecting rod 22 to fit together.

[0021] A motor 15 is installed on the body 1, and the motor 15 is connected to a rotating shaft 13 on one side for drive.

[0022] In this embodiment, the motor 15 drives the rotating rod 10 to rotate, which in turn drives the brush bristles 11 to rotate, brushing the filter holes on the roller body 2. This effectively cleans the material clogging the filter holes, ensuring the separation effect. The length of the brush bristles 11 is greater than the width of the spiral guide plate. When the brush bristles 11 contact the spiral guide plate, they bend to avoid contact. When replacing the brush bristles 11 after prolonged use, the original rotating rod 10 is first disassembled. Then, the first connecting block 12 and the second connecting block 14 on the new rotating rod 10 are aligned. The pressing block 16 is pressed, causing the inclined surfaces of the first wedge block 17 and the second wedge block 18 to press and slide relative to each other. This causes the two second wedge blocks 18 to drive the connecting rod 22. As the locking block 23 approaches each other, the spring 20 is compressed. Then, the connecting rod 22 is inserted into the second connecting block 14, and the pressing block 16 is released. Under the elastic force of the spring 20, the connecting rod 22 and the locking block 23 will be embedded in the docking groove 28 to achieve docking and pre-fixation of the first connecting block 12 and the second connecting block 14. When performing the fixing operation, the operator no longer needs to lift the rotating rod 10 while installing the threaded fasteners. Then, the four inserts 26 on the pressure plate 25 are respectively inserted through the first connecting block 12, the second connecting block 14 and the connecting rod 22 until the pressure plate 25 is fully engaged. Finally, the nut 27 is screwed onto the insert 26. This improves the convenience of fixing and installing the rotating rod 10, while ensuring the stability of the rotating rod 10, and has good practicality.

[0023] It should be noted that the outer layer of the brush bristles 11 is made of non-stick material, the middle layer is made of stainless steel wire as a reinforcing layer, and the inner core is made of Ni-Ti shape memory alloy as an elastic layer. This ensures that the brush bristles 11 can not only effectively clean the filter holes on the roller body 2, but also reduce the problem of fecal adhesion, and have a good service life.

[0024] Example 3 like Figure 3 As shown, in this embodiment, a roller and solid-liquid separator are provided. Compared with embodiment two, in this embodiment, the pressing block 16 is provided with four guide blocks 21 arranged in a ring array, the first connecting block 12 is provided with a groove for the guide blocks 21 to slide, and the locking block 23 is provided with a plurality of equidistant protrusions 24, which are embedded in the interior of the docking groove 28.

[0025] In this embodiment, the guide block 21 and the groove guide and restrict the movement of the pressing block 16, preventing the pressing block 16 from rotating and causing misalignment of the inclined surfaces of the first wedge block 17 and the second wedge block 18. The protrusion 24 can make the locking block 23 more tightly embedded in the docking groove 28, improving the stability during pre-fixation.

[0026] Example 4 like Figure 4 and Figure 5 As shown in the figure, the solid-liquid separator proposed in this embodiment, compared with the second embodiment, is further provided with a feed pipe 29 in the machine body 1, and two fixing rods 30 are provided on the feed pipe 29, and a disc 32 is provided on the fixing rods 30.

[0027] In this embodiment, when diluted feces are conveyed into the interior of the roller body 2 through the feed pipe 29, the material pumped by the pump body is blocked by the disc 32 when it is sprayed out from the feed pipe 29, so as to avoid the material splashing forward and affecting the separation effect.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
