Usually, biomass rich in lignocellulose is selected as raw material, such as crop straw, wood waste, etc. The pretreated biomass raw material is mixed with specific enzyme preparation, and the enzymatic hydrolysis reaction is carried out under suitable temperature, pH value, etc. During the enzymatic hydrolysis process, the enzyme will specifically act on cellulose and hemicellulose in lignocellulose, and hydrolyze them into sugar and other substances, so that lignin can be separated out. Then, through the separation device, lignin can be separated from the reaction system, and further purification and drying treatment can be carried out to obtain lignin product. For example, the prior art disclosed in CN212733046U provides a kind of separation device for enzymatic hydrolysis lignin processing.

[0003] However, the conventional separation device adopts filter screen when processing the separation of residue and liquid of lignin. During the operation process, the lignin needs to be left for a period of time, and after the internal solid particles slowly precipitate, the opening can be opened for the separation of residue and liquid. This process is time-consuming, which leads to low separation efficiency. At the same time, during the liquid discharge stage, the solid particles will adhere to the surface of the filter screen with the water flow, which hinders the discharge of liquid, further reducing the separation efficiency.

[0024] The technical scheme in the embodiments of the utility model will be clearly and completely described below by combining the drawings in the embodiments of the utility model.

[0025] With reference to the drawings in the specification Figures 1-5 The utility model provides a kind of separation device for enzymatic hydrolysis lignin processing, including filter box 1, the filter box 1 top is equipped with the drug spraying mechanism 2 for spraying flocculating agent, the drug spraying mechanism 2 includes medicine storage box 21, the medicine storage box 21 front and rear sides are fixedly provided with multiple nozzles 22, the medicine storage box 21 inside is equipped with stirring paddle one 23, the medicine storage box 21 bottom is rotatably equipped with two stirring paddle two 24.

[0026] Both sides of the top of the filter box 1 are fixed with drive mechanisms 3, which drive the storage tank 21 to move back and forth to evenly spray flocculant into the filter box. At the same time, they drive the first stirring paddle 23 to rotate and the second stirring paddle 24 to rotate synchronously to stir the lignin and flocculant. Specifically, the drive mechanism 3 includes an electric slide module 31 and a rack 32. The electric slide module 31 is a KNK-K45A, and the rack 32 is located on the outside of the electric slide module 31. The sliders in the two electric slide modules 31 are fixed to the left and right walls of the storage tank 21, respectively. The medicine storage tank 21 is connected by a rotating shaft 33 through one side. The rotating shaft 33 is connected to the two stirring paddles 24 by a bevel gear set 34. The bevel gear set 34 includes two bevel gears, which are fixedly sleeved on the rotating shaft 33 and the stirring paddles 24 respectively. The rotating shaft 33, the stirring paddle 23 and the rack 32 are connected by a gear set 35. The gear set 35 includes four spur gears, which are fixedly sleeved on both ends of the rotating shaft 33 and both ends of the stirring paddle 23 respectively. The bottom of the spur gears located at both ends of the rotating shaft 33 meshes with the two racks 32 respectively.

[0027] A water pump 25 is fixedly installed on the top of the medicine storage tank 21. The water pump 25 is an Anglong DN50. The water inlet of the water pump 25 is connected to the inside of the medicine storage tank 21 through the water inlet pipe, and the water outlet of the water pump 25 is connected to multiple nozzles 22 through the water outlet pipe.

[0028] During lignin separation, lignin is transported to filter box 1 via pipeline. Then, water pump 25 is used to draw flocculant from storage tank 21. When the motor in electric slide module 31 drives the lead screw to rotate, the nut and slide inside will move linearly along the axis of the lead screw, causing storage tank 21 to move back and forth. This allows the flocculant sprayed from multiple nozzles 22 to be evenly sprinkled into the lignin. The flocculant can aggregate fine solid particles such as incompletely enzymatically hydrolyzed residues and lignin particles into larger flocs through adsorption, bridging and other effects, thereby accelerating the sedimentation rate of solid particles and improving the efficiency of slag-liquid separation.

[0029] When the storage tank 21 moves back and forth, the gear set 35 on the stirring paddle 23 and the rotating shaft 33 meshes with the rack 32 on the top of the filter box 1 and rotates. When the rotating shaft 33 rotates, it drives the two stirring paddles 24 to rotate through the bevel gear set 34. When the stirring paddle 23 rotates, it can keep the flocculant in the storage tank 21 in a suspended state and avoid uneven concentration due to sedimentation. The stirring paddle 24 stirs the lignin and flocculant in the filter box 1. Through stirring, the flocculant can better contact and act on the fine solid particles in the lignin, thereby improving the flocculation efficiency and further improving the slag-liquid separation efficiency.

[0030] Next, a drain port 4 is provided at the rear end of the filter box 1. A filter screen 5 is fixedly installed inside the drain port 4. A sealing door 6 is provided on the inner wall of the rear end of the filter box 1. A connecting plate 9 is fixedly installed on the top of the sealing door 6. Two electric push rods 10 for driving the connecting plate 9 to rise and fall are fixedly installed at the bottom of the connecting plate 9. The electric push rods 10 are JC35SA1. The electric push rods 10 are located behind the electric slide module 31 and the rack 32. By extending the electric push rods 10, the connecting plate 9 and the sealing door 6 are automatically moved upward. The liquid in the filter box 1 is discharged through the drain port 4, and the solid particles are blocked in the filter box 1 by the filter screen 5, which is convenient for subsequent cleaning and collection by the staff.

[0031] like Figures 1-5 As shown, a liquid inlet 7 is provided on the top of the medicine storage tank 21. A sealing cover 8 is hinged inside the liquid inlet 7. By opening the sealing cover 8, flocculant can be added into the medicine storage tank 21. The water pump 25 is located behind the liquid inlet 7 to prevent the water pump 25 from obstructing the opening of the sealing cover 8.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
