Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a white willow bark processing raw material crushing and alkalization device, comprising a mixing box 1 and a processing box 2. The mixing box 1 serves as the place where white willow bark raw materials are mixed with alkali and other reagents. The crushing mechanism 11 inside the processing box 2 crushes the mixed raw materials to achieve a suitable particle size, which helps the subsequent alkalization reaction to proceed, improves the reaction rate and effect, and provides a uniform mixture for subsequent processing reactions. The right side of the mixing box 1 and the left side of the processing box 2 are connected by a conveying mechanism 10. The conveying mechanism 10 is responsible for smoothly and continuously conveying the mixture in the mixing box 1 to the processing box 2. The processing box 2 is equipped with a crushing mechanism 11 inside, and a proportioning mechanism 12 is equipped on the top of the mixing box 1.

[0031] Reference Figure 2 and Figure 4 The proportioning mechanism 12 includes a proportioning cylinder 121 and a vertical pipe 122 fixedly connected to the proportioning cylinder 121. The bottom of the vertical pipe 122 is fixedly connected to the inner wall of the mixing tank 1. A connecting pipe 123 is fixedly connected to the bottom of the vertical pipe 122. An annular pipe 124 is fixedly connected to the end of the connecting pipe 123 away from the vertical pipe 122. A liquid outlet pipe 125 is evenly arranged at the bottom of the annular pipe 124 to ensure that the alkali is evenly diffused in the mixing tank 1 and to avoid local concentrations that are too high or too low. The liquid outlet pipe 125 is fixedly connected to the bottom of the annular pipe 124. A solenoid valve 126 is provided in the middle of the vertical pipe 122. There are two sets of proportioning cylinders 121. The bottom of the two sets of proportioning cylinders 121 is fixedly connected to the same circular plate 127. The surface of the proportioning cylinder 121 is provided with scale lines. Alkali solution (such as sodium hydroxide solution) is added quantitatively through the two sets of proportioning cylinders 121. The proportioning is precisely controlled by the scale lines and the solenoid valve 126 to ensure that the concentration of alkali solution is uniform.

[0032] Reference Figure 2 and Figure 3The conveying mechanism 10 includes a conveying pipe 101. The mixing box 1 is connected to the processing box 2 through the conveying pipe 101. The conveying mechanism 10 also includes a drive motor 102. The drive motor 102 is fixedly connected to the right side of the processing box 2. A spiral conveying blade 103 is fixedly connected to the left side of the output shaft of the drive motor 102. A part of the spiral conveying blade 103 is located inside the conveying pipe 101, and the other part of the spiral conveying blade 103 is located inside the processing box 2. The spiral conveying blade 103 is driven by the drive motor 102 to convey the mixed material from the mixing box 1 to the processing box 2, thereby realizing continuous feeding.

[0033] Reference Figure 2 and Figure 3 The crushing mechanism 11 includes a rotating shaft 111 and a gear 113. The rotating shaft 111 is rotatably connected to the inner wall of the processing box 2, and the gear 113 is fixedly connected to the outer wall of the rotating shaft 111. The crushing mechanism 11 also includes a rotating shaft 112 and a gear 114. Both the gear 113 and the gear 114 are located on the rear side of the outside of the processing box 2. The rotating shaft 112 is rotatably connected to the inner wall of the processing box 2, and the gear 114 is fixedly connected to the outer wall of the rotating shaft 112. The gear 113 and the gear 114 mesh with each other, and the rotation directions of the gear 113 and the gear 114 are opposite.

[0034] Reference Figure 1 - Figure 3 The crushing mechanism 11 also includes a second drive motor 115 and a guide plate 117. The second drive motor 115 is fixedly connected to the front of the processing box 2. The rear side of the output shaft of the second drive motor 115 is fixedly connected to the front side of the first rotating shaft 111. Crushing rollers 116 are fixedly connected to the outer walls of the first rotating shaft 111 and the second rotating shaft 112. The two sets of crushing rollers 116 rotate in opposite directions. Driven by the second drive motor 115, the raw materials are fully crushed, making the white willow bark raw material particles finer, increasing the reaction surface area, and promoting the full alkalization reaction. The guide plate 117 is fixedly connected to the top of the inner wall of the processing box 2. The cross-sectional shape of the guide plate 117 is set as a triangle, which is conducive to concentrating the white willow bark raw material above the crushing rollers 116.

[0035] Reference Figure 2 and Figure 4 A drive motor 18 is fixedly connected to the bottom of the mixing tank 1. A stirring blade 19 is fixedly connected to the top of the output shaft of the drive motor 18. The stirring blade 19 is driven by the drive motor 18 to mix the white willow bark raw material with the alkali solution, so that the alkalization reaction can be fully carried out. The outer wall of the mixing tank 1 and the outer wall of the processing tank 2 are fixedly connected to the same support base 16. The support base 16 provides a stable support foundation for the entire device and ensures the stability of the equipment during operation. A discharge pipe 20 for discharging the crushed and alkalized finished product is fixedly connected to the bottom left side of the mixing tank 1 for subsequent processing.

[0036] Working principle: During use, white willow bark raw material is put into the processing box 2. After being guided by the guide plate 117, the raw material falls above the crushing roller 116 under the action of gravity. The second drive motor 115 drives the first rotating shaft 111 to rotate. The first gear 113 on the first rotating shaft 111 meshes with the second gear 114, driving the second rotating shaft 112 to rotate synchronously. This causes the two sets of crushing rollers 116 to rotate in opposite directions, crushing the white willow bark raw material as it falls. Then, the first drive motor 102 of the conveying mechanism 10 drives the spiral conveying blades 103 to rotate, pushing the crushed white willow bark raw material into the processing box 2 through the conveying pipe 101.

[0037] Based on the weight of the white willow bark raw material, the required volume of alkali solution (NaOH solution) and dilution water is added to the two sets of mixing cylinders 121 through the scale lines of the mixing mechanism 12. Then, the solenoid valve 126 is opened. When the solenoid valve 126 is opened, the alkali solution flows through the vertical pipe 122, the connecting pipe 123 and the annular pipe 124, and finally enters the mixing tank 1 evenly through the liquid outlet pipe 125. The two sets of mixing cylinders 121 accurately add the required liquid volume according to the surface scale lines. The solenoid valve 126 in the middle of the vertical pipe 122 controls the liquid flow rate to ensure that the liquid is injected into the mixing tank 1 in a predetermined ratio.

[0038] At the same time, the drive motor 18 drives the stirring blades 19 to rotate, which fully stirs the white willow bark raw material and alkali solution in the mixing box 1, so that the white willow bark raw material and alkali solution are fully mixed and alkalized (temperature controlled at 50-60℃, pH value maintained at 10-12), which destroys the plant cell wall and increases the dissolution rate of effective ingredients (such as salicin).

[0039] After being crushed, the white willow bark raw material undergoes further alkalization reaction in the processing tank 2. The crushed and alkalized material is discharged through the discharge pipe 20 and enters the subsequent drying or extraction process to finally obtain high-purity white willow bark alkalization products (such as salicin concentrate). The entire device is integrated into a structure through the support base 16 to ensure the stability of the equipment during operation. The discharge pipe 20 facilitates the discharge of the crushed and alkalized material and is easy to connect with the subsequent drying or extraction process, realizing a seamless production mode throughout the process, which further improves production efficiency and product quality stability.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
