Technical Field

[0001] The utility model relates to the field of bio-based rubber filler processing, in particular to a novel flocculation and sedimentation device for preparing bio-based rubber filler. Background Art

[0002] The most important filler in rubber product manufacturing is carbon black. However, carbon black uses petroleum as raw material, has high energy consumption in production, serious environmental pollution during production and use, and limited resources. Currently, both domestic and foreign countries are vigorously conducting research and development of bio-based raw materials to replace carbon black. The lignin in papermaking black liquor has a unique polymer structure. The black liquor generated during papermaking wastewater treatment is used to flocculate and precipitate clay minerals to achieve micro-nano dispersion of clay minerals in rubber, meeting the requirements for flocculated and precipitated clay minerals to be used as fillers in rubber products. This provides solutions to the environmental protection technical problems of the papermaking industry and the resource recycling of the rubber industry.

[0003] Current black liquor desalination technology requires reducing the amount of alkali in the pulping process. Filtering and sedimentation with a variety of filter membranes with different pore sizes are required to achieve low-concentration and high-efficiency desalination. Traditional flocculation and sedimentation devices used in the preparation of bio-based rubber fillers require constant replacement of filter membranes when filtering sediments. This operation is cumbersome, time-consuming, and labor-intensive, resulting in low flocculation and sedimentation treatment efficiency.

[0004] To solve the above problems, we proposed a new flocculation and sedimentation device for the preparation of bio-based rubber fillers, which improves the shortcomings of the existing technology. Utility Model Content

[0007] Preferably, the filter membrane disc includes an outer ring, an inner ring, a support plate, a filter membrane and a sealing ring, four support plates are evenly connected between the outer surface of the inner ring and the inner surface of the outer ring, and a filter membrane is also arranged between the inner ring and the outer ring, the outer edge of the filter membrane is fixed on the inner wall of the outer ring, the inner edge of the filter membrane is fixed on the outer surface of the inner ring, and a sealing ring is also adhered to the outer side of the outer ring.

[0008] Preferably, the structure of the filter membrane disc 1 is the same as that of the filter membrane disc 2, and the filter holes on the filter membrane disc 1 are smaller than the filter holes on the filter membrane disc 2.

When the rotating rod is lifted, the filter membrane disc 1 and the filter membrane disc 2 rise with it, thereby achieving multiple filtrations and taking out the filtered flocculated particles. The new flocculation and sedimentation device for preparing bio-based rubber fillers using this structural design can complete multiple filtrations at one time without the need for frequent replacement of filter membranes. The operation is time-saving and labor-saving, and can effectively improve the flocculation and sedimentation treatment efficiency, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In this embodiment, the filter membrane disc 8 includes an outer ring 81, an inner ring 82, a support plate 83, a filter membrane 84 and a sealing ring 85. Four support plates 83 are evenly connected between the outer surface of the inner ring 82 and the inner surface of the outer ring 81, and a filter membrane 84 is also provided between the inner ring 82 and the outer ring 81. The outer edge of the filter membrane 84 is fixed on the inner wall of the outer ring 81, and the inner edge of the filter membrane 84 is fixed on the outer surface of the inner ring 82. A sealing ring 85 is also adhered to the outer side of the outer ring 81. By putting the inner ring 82 on the bottom of the rotating rod 5, the filter membrane disc 8 can be fixed on the rotating rod 5, and at the same time, it can be allowed to slide on the rotating rod 5 to avoid rotating with the rotating rod 5.

[0024] In this embodiment, the structure of filter membrane disc 1 8 is the same as that of filter membrane disc 2 9, and the filter holes on filter membrane disc 1 8 are smaller than the filter holes on filter membrane disc 2 9, which can achieve multiple filtrations at one time, saving time and effort, and greatly improving the flocculation sedimentation treatment efficiency.

[0025] In this embodiment, a limiting ring 11 is sleeved and fixed on the bottom of the rotating rod 5, and the filter membrane disc 2 9 is pressed against the bottom of the limiting ring 11, which makes it convenient to press the filter membrane disc 2 9 to the bottom of the sedimentation tank 1, saving space in the sedimentation tank 1.

[0026] In this embodiment, a nut 12 is connected to the thread at the bottom of the rotating rod 5, and the filter membrane disc 8 is pressed on the nut 12, which is convenient for fixing and disassembly, and also convenient for configuring a filter membrane with suitable filter holes according to needs.

[0027] In this embodiment, a downpipe 13 is provided at the bottom center of the sedimentation tank 1, and the rotating rod 5 can be inserted into the downpipe 13 when descending, so that the filter membrane disc 1 8 and the filter membrane disc 2 9 can be pressed to the bottom of the sedimentation tank 1, saving space and preventing the filter membrane disc 1 8 and the filter membrane disc 2 9 from sticking together, ensuring that both can achieve filtration.

[0028] In this embodiment, a controller 14 is further provided on the hanging frame 2, and the controller 14 is electrically connected to the cylinder 3 and the motor 7 to facilitate the operation of the control device.

[0029] The principle and advantages of this utility model: Connect the controller 14 to the power supply, and then Figure 2 As shown, the cylinder 3 is turned on by the controller 14 to extend it, and the rotating rod 5 is lowered. The bottom end of the rotating rod 5 is inserted into the lower liquid pipe 13, and the bottom of the sedimentation tank 1 blocks the filter membrane disc 1 8 from descending. The spring 10 is compressed, shortening the distance between the filter membrane disc 1 8 and the filter membrane disc 2 9, which can save the internal space of the sedimentation tank 1 and process more raw materials. Then, the black liquor is poured into the sedimentation tank 1, and then the flocculant is poured in. The motor 7 is turned on to rotate the rotating rod 5 and the stirring rod 6 to stir the raw materials, so that the flocculant is fully in contact with the raw materials, which helps to improve the flocculation efficiency. When the motor 7 is turned off to stop stirring, the precipitate descends and first falls on the filter membrane disc 2 9, and then as shown in FIG. Figure 1As shown, the cylinder 3 is turned on and allowed to contract, and the filter membrane disc 2 9 and the filter membrane disc 1 8 are lifted up. Since the filter holes on the filter membrane disc 1 8 are smaller than the filter holes on the filter membrane disc 2 9, the filter membrane disc 2 9 first filters out large particles of sediment, and the filter membrane disc 1 8 filters out small particles of sediment. The filter membrane disc 2 9 and the filter membrane disc 1 8 are lifted out of the sedimentation tank 1 to clean out the filtered sediment. The novel flocculation and sedimentation device for preparing bio-based rubber filler using this structural design can complete multiple filtrations at one time without the need for frequent replacement of filter membranes. The operation saves time and effort, and can effectively improve the flocculation and sedimentation treatment efficiency, thereby improving practicality.
