Description

Technical Field

[0001] The utility model relates to the technical field of warm wheel rubber production, in particular to a solid-liquid separation device for warm wheel rubber production. Background Art

[0002] Wenlun gum is an industrial-grade microbial polysaccharide, mainly produced by Alcaligenes or Sphingomonas through aerobic deep fermentation. Its production process mainly includes strain and fermentation preparation, fermentation culture and fermentation liquid pretreatment, drying and crushing. Its production principle is based on microbial fermentation technology, and the soluble exopolysaccharide Wenlun gum is synthesized and secreted through strain metabolism and fermentation regulation.

[0003] In the production process of Weinlun rubber, the solid-liquid separation device is mainly used to extract and purify Weinlun rubber from the fermentation broth.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figure 1-Figure 3 As shown together, a warm wheel glue solid-liquid separation device includes a device body 1, two coaxially arranged separation chambers 2 inside the device body 1, a separation cylinder 3 is rotatably installed in the separation chamber 2, a pusher extrusion screw 4 is rotatably installed inside the separation cylinder 3, the pusher extrusion screw 4 and the separation cylinder 3 are driven to rotate by a power mechanism 5, a filter cleaning assembly 6 is rotatably installed at the upper end of the separation chamber 2, and the filter cleaning assembly 6 is driven to rotate by a driving mechanism 7.

[0027] In the production process of Wenlun rubber, Alcaligenes or Sphingomonas is inoculated into a sterile fermentation medium containing a carbon source, a nitrogen source, an inorganic salt and water for fermentation. The obtained fermentation liquid is extracted to obtain a mixed material solution, and then the material solution can be subjected to solid-liquid separation to obtain a solid Wenlun rubber semi-finished product.

[0028] In this embodiment, a dual-chamber separation structure is adopted, and the two pushing and squeezing screws 4 simultaneously perform solid-liquid separation processing on the material, thereby effectively improving the processing capacity of the solid-liquid separation device.

[0029] In this embodiment, the filter cleaning assembly 6 is used to clean the wall of the separation cylinder 3 to avoid the problem of the sticky warm wheel glue adhering to the separation cylinder 3 for a long time and clogging the filter holes 31, thereby ensuring the processing efficiency and processing effect of the solid-liquid separation device. At the same time, it also avoids the problem of the warm wheel glue being contaminated and deteriorated due to long-term attachment to the separation cylinder 3, thereby ensuring the quality of the finished product of the warm wheel glue.

[0030] like Figure 1 and Figure 2 As shown in common, a number of spaced filter holes 31 are evenly distributed on the side walls of the separation cylinder 3, the interior of the separation cylinder 3 is connected to the separation chamber 2 through the filter holes 31, and a number of spaced discharge ports 32 are provided on the side wall of one end of the separation cylinder 3 close to the discharge end of the pushing and extruding screw 4, and a solid outlet 11 is provided at the bottom of the device body 1, and the position of the discharge port 32 corresponds to the position of the solid outlet 11.

[0031] In this embodiment, the interior of the separation chamber 2 is connected to a liquid outlet pipe 12 .

[0032] Among them, a feed shaft tube 8 is fixed to the feed end of the pushing and extruding screw 4, and the feed shaft tube 8 is coaxially arranged with the pushing and extruding screw 4. The end of the feed shaft tube 8 extends out of the end of the device body 1, and a feed pipe 81 is passed through the inside of the feed shaft tube 8. A feed cavity 82 is provided inside the feed end of the pushing and extruding screw 4, and the feed cavity 82 is connected with the feed pipe 81. A number of feed ports 83 connected with the inside of the separation cylinder 3 are arranged at intervals on the side wall of the feed cavity 82.

[0033] The process of using the utility model to carry out solid-liquid separation treatment of the material solution is as follows:

[0034] First, the material solution enters the feed chamber 82 through the feed pipe 81 and enters the separation cylinder 3 through the feed port 83. At the same time, the power mechanism 5 drives the pushing and squeezing screw 4 and the separation cylinder 3 to rotate differentially. The pushing and squeezing screw 4 cooperates with the inner wall of the separation cylinder 3. The liquid contained in the material solution enters the separation chamber 2 through the filter hole 31 of the separation cylinder 3. The liquid material in the separation chamber 2 is discharged from the device body 1 through the liquid outlet pipe 12.

[0035] Afterwards, the pushing and squeezing screw 4 continuously pushes the material forward, and the solid material moved to the conveying end falls into the solid outlet 11 through the discharge port 32, and then falls into the receiving container below through the solid outlet 11.

[0036] like Figure 1-Figure 2 As shown together, the power mechanism 5 includes a first drive motor 51 fixed on the device body 1, and a first drive gear 52 and a second drive gear 53 are fixedly mounted on the motor shaft of the first drive motor 51. A first driven gear 54 is fixedly mounted on the end of the feed shaft tube 8 extending out of the separation cylinder 3, and the first driven gear 54 is engaged with the first drive gear 52. A second driven gear 55 is fixedly mounted on the end of the separation cylinder 3 extending out of the device body 1, and the second driven gear 55 is engaged with the second drive gear 53.

[0037] In this embodiment, the module ratio of the first drive gear 52 and the first driven gear 54 is different from the module ratio of the second drive gear 53 and the second driven gear 55, so that the first drive motor 51 can drive the separation drum 3 and the pusher screw 4 to rotate differentially.

[0038] like Figure 1 As shown, the pushing extrusion screw 4 includes a rotating rod arranged axially along the separation cylinder 3, and the rotating rod includes a feed end rod portion 41, a reducing rod portion 42 and a discharge end rod portion 43 arranged in sequence along the material conveying direction. The feed port 83 is arranged on the peripheral wall of the feed end rod portion 41, and the feed end rod portion 41, the reducing rod portion 42 and the discharge end rod portion 43 are commonly provided with an extrusion spiral blade 44 arranged in a bolt shape.

[0039] Example 2

[0040] This embodiment is basically the same as the first embodiment, except that:

[0041] like Figure 1-Figure 3 As shown in common, the filter cleaning assembly 6 includes a rotating shaft 61 rotatably installed in the device body 1, the rotating shaft 61 is arranged along the axial extension of the pushing and extruding screw 4, and the two ends of the rotating shaft 61 respectively extend into the two separation chambers 2. A number of cleaning brushes 62 are fixedly installed at both ends of the rotating shaft 61 extending into the separation chamber 2, and the bristles of the cleaning brush 62 are tightly attached to the outer wall of the separation cylinder 3.

[0042] In this embodiment, when cleaning is required, the power mechanism 5 drives the separation cylinder 3 and the push and squeeze screw 4 to rotate, and at the same time the driving mechanism 7 drives the rotating shaft 61 and the cleaning brush 62 to rotate continuously, and the cleaning brush 62 is used to clean the cylinder wall of the separation cylinder 3, thereby avoiding the problem of solid materials clogging the filter holes 31.

[0043] Moreover, the filter cleaning assembly 6 also includes a plurality of high-pressure nozzles 63 fixed on the peripheral wall of the rotating shaft 61. The high-pressure nozzles 63 are connected to the hollow cavity inside the rotating shaft 61. A water inlet shaft pipe 64 coaxially arranged with the rotating shaft 61 is fixed on the device body 1. Both ends of the rotating shaft 61 are rotatably installed on the water inlet shaft pipe 64. The hollow cavity inside the rotating shaft 61 is connected to the high-pressure water inlet pipe 65 through the water inlet shaft pipe 64.

[0044] In this embodiment, high-pressure cleaning water enters the rotating shaft 61 through the high-pressure water inlet pipe 65 and the water inlet shaft pipe 64, and then flushes the wall of the separation cylinder 3 through the high-pressure nozzle 63 to flush away the solid material (i.e., the semi-finished product of the warm wheel glue) attached to the wall of the separation cylinder 3, thereby achieving thorough cleaning of the solid material attached to the separation cylinder 3.

[0045] In addition, the driving mechanism 7 includes a second driving motor 71 fixedly mounted on the top of the device body 1, a third driving gear 72 fixedly mounted on the motor shaft of the second driving motor 71, and a third driven gear 73 fixedly mounted on the rotating shaft 61, and the third driven gear 73 is meshed with the third driving gear 72.
