Description

Technical Field

[0001] The invention relates to the field of separation and extraction devices, and in particular to a fiber separation and extraction device for straw recovery and a use method thereof. Background Art

[0002] Straw fiber recycling is a technology that converts crop straw into useful resources. Straw is a waste generated in the agricultural production process and is usually burned or discarded, which not only wastes resources but also pollutes the environment. Through straw fiber recycling technology, straw can be converted into cellulose, bio-organic fertilizer and other useful products to achieve the recycling of resources.

[0003] When separating and extracting straw fibers, the straw needs to be pretreated - alkaline solution pretreatment - enzymatic treatment - separation and extraction - washing and drying - recycling - quality control and other processes. When separating and extracting straw fibers, in order to improve the efficiency of straw fiber separation and extraction, the enzymatically treated straw will be ground, and then the straw will be centrifuged and filtered to separate the cellulose.

[0004] When grinding the straw, a grinder is usually used for grinding. The existing grinder is usually composed of a frame, a casing, a grinding cover, a grinding disc, a driving mechanism and a feeding and discharging system. It is usually directly installed on the inside of the frame and the casing using bolt limiters. Therefore, when using it, the grinder needs to be moved as a whole, which is not convenient for disassembling and moving it.

[0029] In particular, the integrated bracket 1 includes a support leg 11, a connecting shell 12 and a connecting rod 13. The support leg 11 is clamped on the side of the grinding cover 2, and the connecting shell 12 is rotatably set on one side of the support leg 11. One end of the connecting rod 13 is connected to the mounting assembly 5, and one end of the outer wall of the connecting rod 13 is slidably sleeved with the connecting shell 12. The connecting rod 13 is L-shaped, so that when the connecting rod 13 is slidably sleeved with the connecting shell 12, the connecting shell 12 has a portion located at the bottom of the mounting assembly 5. The integrated bracket 1 also includes a bearing frame 14, a pin shaft 19, a triangular plate 15, a mounting shell 16, a connecting sleeve 17 and a support plate 18. The bearing frame 14 is fixedly connected to one side of the support leg 11, one side of the bottom of the connecting shell 12 is fitted with the bearing frame 14, and one end of the connecting shell 12 is rotatably connected to the bearing frame 14 through the pin shaft 19, as shown in FIG. Figure 5 As shown, after the supporting leg 11 and the connecting shell 12 are disassembled, the connecting shell 12 can be placed parallel to the supporting leg 11, so as to facilitate its storage and transportation. The triangular plate 15 is fixedly connected between the supporting frame 14 and the supporting leg 11. The triangular plate 15 can improve the stability of the supporting frame 14 on the supporting shell 12, and under the limitation of the supporting frame 14, the maximum rotation angle of the connecting shell 12 is ninety degrees. The mounting shell 16 is fixedly connected to the outside of the grinding cover 2, and the connecting sleeve 17 is fixedly connected to the outside of the mounting shell 16. The top of the outer wall of the supporting leg 11 is slidably connected with the connecting sleeve 17. The supporting plate 18 is fixedly connected to the outside of the supporting leg 11, and the top of the supporting plate 18 is fitted with the connecting sleeve 17. The mounting shell 16 and the connecting sleeve 17 are both located in the middle of the outer wall of the grinding cover 2. Therefore, under the limitation of the supporting plate 18, the height of the grinding cover 2 installed on the supporting leg 11 through the connecting sleeve 17 is the same, and a notch corresponding to the connecting shell 12 is opened on one side of the supporting plate 18.

The connecting bearing 53 is installed on the top of the outer wall of the sealing cover 51. The connecting bearing 53 is located inside the first annular groove. The connecting bearing 53 can improve the rotation stability of the grinding table 3.

[0031] In particular, the locking assembly 52 includes a connecting ring 521, a locking rod 522, a locking hole 528 and a support spring 526.

The outer wall of the locking rod 522 is slidably inserted and sleeved with the sealing cover 51. The locking hole 528 is opened at the top of the connecting shell 12 and the connecting rod 13. The outer wall of the locking rod 522 is slidably sleeved with the inner cavity of the locking hole 528, which can ensure the stability of the connection between the connecting shell 12 and the connecting rod 13. The support spring 526 is located at the connecting ring 521. At the top of the grinding table 3, the support spring 526 can give the connecting ring 521 an elastic squeezing force, thereby ensuring the stability of the connecting ring 521 driving the locking rod 522 to engage with the connecting shell 12 and the connecting rod 13. By pulling out the locking rod 522, the connecting shell 12 and the connecting rod 13 can be disassembled, and the support spring 526 acts on the grinding table 3 with an elastic force toward the grinding cover 2. The support spring 526 can give the grinding table 3 an elastic force toward the grinding cover 2, so that when the grinding table 3 and the grinding cover 2 are both worn to a certain extent, the grinding table 3 and the grinding cover 2 can still extrude and grind the straw material.

[0032] Furthermore, the locking assembly 52 also includes a fixing block 523, a fixing ring 524, a positioning rod 525, a through hole, a second annular groove and a plane bearing 527.

The top of the fixing block 523 is provided with a positioning hole corresponding to the positioning rod 525. Under the limitation of the grinding table 3, the fixing ring 524 can drive the positioning rod 525 to lock the fixing block 523. In order to ensure the stability of the installation of the drive component 4, the positioning rod 525 can be directly pulled out by removing the grinding table 3, thereby improving the convenience of disassembly. Through holes are opened on the sealing cover 51, the connecting rod 13 and the connecting ring 521. The outer wall of the positioning rod 525 is slidably connected with the through hole. The second annular groove is opened at the bottom of the grinding table 3. The plane bearing 527 is located at the top of the fixed ring 524. The plane bearing 527 and the fixed ring 524 are both located inside the second annular groove. The support spring 526 can give the grinding table 3 an elastic supporting force through the fixed ring 524 and the plane bearing 527, and the plane bearing 527 can reduce the friction between the fixed ring 524 and the grinding table 3.
