DETAILED DESCRIPTION

[0024] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiment of the utility model is explained in detail below with the help of the attached drawings of the specification.

[0025] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, and the person skilled in the art can make similar generalization without violating the connotation of the utility model, therefore the utility model is not limited by the following disclosed specific embodiments.

[0026] Secondly, the "one embodiment" or "embodiments" referred to herein are intended to encompass a particular feature, structure, or characteristic in at least one implementation of the present application. The appearances of the "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive.

[0027] Embodiment 1

[0028] With reference to Figures 1-5 For the first embodiment of the present application, the embodiment provides a preparation device for lignin source culture medium, comprising,

[0029] The bearing mechanism 100 comprises a cylinder body 101, a feeding pipe 102 fixedly installed at the top of the cylinder body 101, and a support seat 103 fixedly installed at the top of the cylinder body 101.

[0030] The mixing mechanism 200 comprises a mixing assembly 201 arranged in the inner cavity of the cylinder body 101, a stirring assembly 202 arranged at the bottom of the mixing assembly 201, a shaft seat 203 fixedly installed at the bottom of the stirring assembly 202, and an elastic assembly 204 arranged outside the shaft seat 203.

[0031] The bearing mechanism 100 provides a stable reaction space, and the mixing assembly 201 in the mixing mechanism 200 cooperates with the stirring assembly 202 to realize the full flow of the material in multiple directions and multiple angles.

[0032] Specifically, the bearing mechanism 100 further comprises a plurality of support legs 104 fixedly installed on the outer surface of the cylinder body 101, and a discharge valve pipe 105 fixedly installed at the bottom of the cylinder body 101, and the mixing mechanism 200 further comprises an arc sleeve 205 fixedly installed in the inner cavity of the cylinder body 101, a plurality of rack gears 206 fixedly installed on the inner wall of the arc sleeve 205, and a servo motor 207 fixedly installed at the top of the support seat 103.

[0033] The rack gears 206 on the inner wall of the arc sleeve 205 interact with the rack gears 206, so that the flow direction and speed of the material change, thereby generating a more complex flow field. This complex flow field helps to break the agglomeration structure of lignin, so that the lignin particles are more uniformly dispersed in the solution, and the stirring effect and the dispersion uniformity of lignin are improved.

[0034] Further, the mixing assembly 201 further comprises a shaft 201a fixedly installed at the output end of the servo motor 207, a connecting rod 201b fixedly installed outside the shaft 201a, a spiral stirring plate 201c fixedly installed outside the connecting rod 201b, and a fixed block 201d fixedly installed at the bottom of the shaft 201a.

[0035] The spiral shape of the spiral stirring plate 201c in the mixing assembly 201 is designed to form an up-and-down circulating flow pattern of the material during stirring, which helps to break the agglomerates of lignin that may be formed in the solution, and makes the lignin powder more uniformly dispersed in water, avoiding its aggregation in local areas, and providing a more uniform reaction system for subsequent processing steps. When preparing the lignin solution, the stirring action of the spiral stirring plate 201c can continuously turn the sinking lignin powder upwards, so that it is fully mixed with water, improving the dispersion effect.

[0036] Preferably, the stirring assembly 202 includes an output shaft 202a fixedly installed at the bottom of the fixed block 201d, a groove seat 202b movably sleeved on the outer surface of the output shaft 202a, a plurality of rotating shafts 202c rotatably installed on the outer side of the groove seat 202b, and an inclined paddle 202d fixedly installed at the end of the rotating shaft 202c.

[0037] The inclined design of the inclined paddle 202d in the stirring assembly 202 causes the material to flow at multiple angles during stirring, which further enhances the mixing effect of the material. When the inclined paddle 202d rotates, it not only causes the lignin solution to flow in the horizontal direction, but also causes certain disturbance in the vertical direction, so that the lignin particles can be fully stirred and dispersed in all directions.

[0038] Further, the elastic assembly 204 includes a cross rod 204a fixedly installed on the outer surface of the shaft 201a, a reset member 204b provided at the end of the cross rod 204a, a triangular block 204c fixedly installed on the outer side of the reset member 204b, and a wall scraper 204d provided on the top of the triangular block 204c. The reset member 204b includes a sleeve 204b-1 fixedly installed at the end of the cross rod 204a, a reset spring 204b-2 fixedly installed in the inner cavity of the sleeve 204b-1, a movable block 204b-3 fixedly installed at the end of the reset spring 204b-2, a limiting block 204b-4 fixedly installed on the outer side of the movable block 204b-3, and a limiting groove 204b-5 fixedly installed on the inner wall of the sleeve 204b-1, and the limiting block 204b-4 is movably clamped on the inner wall of the limiting groove 204b-5.

[0039] The cross rod 204a rotates with the shaft 201a, and the reset member 204b causes the triangular block 204c to periodically elastically move during rotation through the action of the reset spring 204b-2, thereby driving the wall scraper 204d to periodically scrape the inner wall of the cylinder 101.

[0040] In use, the raw materials for preparing the lignin source culture medium are added into the barrel 101 through the feeding pipe 102, the servo motor 207 is started, the shaft rod 201a is rotated, the connecting rod 201b and the spiral stirring plate 201c are rotated, the materials in the barrel 101 are stirred, the materials form up-down circulating flow, the fixed block 201d at the bottom of the shaft rod 201a drives the output shaft 202a of the stirring assembly 202 to rotate, the groove seat 202b, the rotating shaft 202c and the inclined paddle 202d are rotated, the materials produce multi-angle flow, and the mixing effect is enhanced;

[0041] Meanwhile, the cross rod 204a on the outer surface of the shaft rod 201a rotates with the shaft rod, the reset spring 204b-2 drives the triangular block 204c to change the position and deform and reset when the triangular block 204c collides with the rack 206 in the inner cavity of the arc-shaped sleeve 205 in the rotating process, the movable block 204b-3 moves in the sleeve 204b-1, the limiting block 204b-4 moves in the limiting slot 204b-5 to play a limiting role, and then the triangular block 204c is periodically bounced;

[0042] Subsequently, the wall scraper 204d performs periodic action, the limiting strip 204d-1 cooperates with the clamping strip 204d-2, the limiting rod 204d-3 plays an auxiliary limiting role, the scraper 204d-4 scrapes the inner wall of the barrel 101, prevents the materials from adhering to the wall, and can also disturb the materials close to the inner wall to fully participate in mixing, and finally the prepared lignin source culture medium can be discharged through the discharge valve pipe 105 at the bottom of the barrel 101.

[0043] To sum up, the mixing assembly 201 and the stirring assembly 202 in the mixing mechanism 200 cooperate to enable the materials to fully flow in multiple directions and multiple angles, the reset member 204b in the bouncing assembly 204 drives the wall scraper 204d to periodically bounce and scrape the inner wall of the barrel 101 to prevent the materials from adhering, compared with the traditional stirring type preparation device, the device can effectively avoid the problem of lignin agglomeration caused by unreasonable design or stirring speed of the stirring paddle, ensure that the lignin powder is uniformly dispersed in water, provide a uniform reaction system for subsequent chemical reaction and utilization of lignin by microorganisms, and significantly improve the preparation quality and utilization efficiency.

[0044] Example 2

[0045] Reference Figure 2 and Figure 5 This embodiment provides the wall scraper 204d for scraping the lignin adhering to the wall, which is different from the previous embodiment.

[0046] Specifically, the wall scraper 204d includes a limiting strip 204d-1 fixedly installed on the top of the triangular block 204c, a clamping strip 204d-2 movably clamped in the inner cavity of the limiting strip 204d-1, a limiting rod 204d-3 fixedly installed on the outer side of the clamping strip 204d-2, and a scraper plate 204d-4 fixedly installed on the side of the clamping strip 204d-2 away from the limiting rod 204d-3.

[0047] The scraping action of the wall scraper 204d can prevent the lignin solution from adhering to the inner wall of the cylinder 101 due to viscosity, and avoid the problem of uneven dispersion caused by the accumulation of lignin on the wall. The periodic bouncing and scraping action can produce a certain disturbance to the lignin solution close to the inner wall of the cylinder 101, so that this part of the solution can also fully participate in the stirring and mixing process, further improving the uniform dispersion degree of lignin in the whole reaction system.

[0048] In use, the wall scraper 204 will rotate according to the stirring assembly 202. The limiting rod 204d-3 limits the movement of the clamping strip 204d-2 during rotation, ensuring the normal work of the scraper plate 204d-4, which scrapes the lignin on the inner wall of the cylinder 101.

[0049] It should be noted that the scraper plate 204d-4 is made of silica gel material. When the elastic assembly 204 rotates and drives the triangular block 204c to collide with the rack 206 in the inner cavity of the arc-shaped sleeve 205, the position of the triangular block 204c will change. However, due to the elasticity and flexibility of silica gel, the position change can still ensure good adhesion to the inner wall of the cylinder 101, and the wall is in close contact, ensuring the scraping effect.

[0050] In summary, the scraper plate 204d-4 can effectively scrape the inner wall of the cylinder 101, prevent the material from adhering to the wall, and also disturb the material close to the inner wall to fully participate in the mixing.
