Description

Technical Field

[0001] The utility model relates to the technical field of folic acid production, in particular to a high-efficiency mixing device for industrial folic acid production. Background Art

[0002] Folic acid is a water-soluble vitamin. It is produced by mixing and purifying two raw materials, oxalic acid solution and aminobenzoic acid, and then adding an oxidant to carry out an oxidation reaction to obtain folic acid.

[0003] The current folic acid mixing equipment is shown in the patent document with application number 202223495069.5, which discloses a mixing device for folic acid production, including a stirring bin, a feeding port installed at the upper end of the stirring bin and a discharge pipe installed on one side of the bottom end of the stirring bin. A rotating top shaft is provided inside the stirring bin, and a rotating bottom shaft is sleeved on the bottom of the rotating top shaft. The outer walls of the rotating bottom shaft and the rotating top shaft are distributed with several groups of stirring blades at longitudinal intervals. The bottom center of the stirring bin is provided with a bidirectional rotating mechanism that can drive the rotating bottom shaft and the rotating top shaft to rotate.

[0004] Although the mixing device can improve the mixing effect of the raw materials through bidirectional rotation stirring, the stirring height of the stirring rod is the same at the same position regardless of the bidirectional stirring of the mixing device or the currently commonly used unidirectional rotation stirring. That is to say, the stirring rod of the current mixing device can only continuously stir on a horizontal plane at a fixed height, and it is difficult to achieve simultaneous stirring and mixing on the horizontal and vertical planes, resulting in a low mixing efficiency of the raw materials.

[0005] To this end, we propose an efficient mixing device for industrial folic acid production. Utility Model Content

[0008] Furthermore, the plurality of stirring rods are distributed on both sides of the central rod, the stirring rods on each side are equidistantly distributed along the axial direction of the central rod, and the positions of the stirring rods on both sides are staggered with each other.

[0009] Furthermore, a scraper is rotatably installed on the inner bottom of the mixing bin.

[0021] 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.

[0022] See also Figure 1-4 , an efficient mixing device for industrial folic acid production, comprising a mixing bin 1, a bin cover 2 and a feed pipe 3, wherein the feed pipe 3 is obliquely connected to the side wall of the mixing bin 1 for introducing raw materials into the bin, the bin cover 2 is installed at the top of the mixing bin 1, and a center rod 4 is passed through the middle of the bin cover 2 from top to bottom. The center rod 4 is provided with a plurality of stirring rods 41 on an outer wall of a section extending into the mixing bin 1, and a hanger 5 is installed at one end of the center rod 4 extending outside the mixing bin 1, and a motor 6 for driving the center rod 4 to rotate is installed on the hanger 5, and a cylinder 7 for driving the hanger 5 to rise and fall is installed on the bin cover 2, the bottom end of the cylinder 7 is fixed to the bin cover 2, and the top end of the output shaft of the cylinder 7 is fixed to the hanger 5, so that when the center rod 4 rotates, the center rod 4 is driven to rise and fall, so that the stirring rod 41 moves up and down while rotating, thereby improving the mixing efficiency.

[0023] See also Figure 2 In order to further improve the mixing effect, a number of stirring rods 41 are arranged on both sides of the central rod 4. The stirring rods 41 on each side are equidistantly distributed along the axial direction of the central rod 4, and the positions of the stirring rods 41 on both sides are staggered, so that the longitudinal spacing distance of the stirring rods 41 is reduced, and the stirring surfaces of the stirring rods 41 on both sides are staggered, so as to stir a wider range of raw materials.

[0024] See also Figure 2 The inner bottom of the mixing bin 1 is rotatably installed with a scraper 9, which is a U-shaped structure, and the scraper 9 is tightly fitted with the inner bottom surface and the inner circumferential side surface of the mixing bin 1, so that the inner wall of the mixing bin 1 can be scraped while rotating, reducing the residual raw materials on the inner wall and ensuring the adequacy of the mixing. At the same time, when the scraper 9 rotates, it can also scrape the raw materials on the discharge port 11, which is beneficial to reduce the problem of blockage of the discharge port 11 during discharging. In order to facilitate the control of the rotation of the scraper 9, the middle part of the scraper 9 is connected with a secondary rod 8, and the inner part of the secondary rod 8 is connected with the auxiliary rod 8. A slot 81 is provided on the part, and an insertion rod 42 is provided inside the center rod 4. There is an insertion cavity between the insertion rod 42 and the center rod 4, which is convenient for inserting the auxiliary rod 8. After the auxiliary rod 8 is inserted, the insertion rod 42 can be inserted into the slot 81. The cross-sectional structure of the insertion rod 42 and the slot 81 adopts a rectangular structure, so that the center rod 4 can drive the auxiliary rod 8 to rotate without affecting the lifting and lowering movement of the center rod 4 itself. At the same time, after insertion, the outer wall of the auxiliary rod 8 fits tightly with the inner wall of the center rod 4, so that the raw materials on the surface of the auxiliary rod 8 can be scraped off when the center rod 4 descends.

[0025] See also Figure 1-2 and Figure 3 A guide rod 71 parallel to the telescopic direction of the cylinder 7 is also installed on the bin cover 2, and the top plate of the hanger 5 is slidably connected to the guide rod 71. A notch is provided on the side of the top plate of the hanger 5, which coincides with the outer wall of the guide rod 71, so that the sliding action between the two can be used to limit the center rod 4 and reduce its shaking and deflection during the lifting process.

[0026] See also Figure 4 In order to facilitate the motor 6 to drive the center rod 4 to rotate, the output shaft of the motor 6 is connected to a bevel gear 1 61, the lower edge of the bevel gear 1 61 is connected to a bevel gear 2 62, and the bevel gear 2 62 is coaxially fixed to the top of the center rod 4, and then the rotation direction of the output shaft of the motor 6 is changed by the bevel gear 1 61 and the bevel gear 2 62, so as to drive the center rod 4 to rotate.

[0027] See also Figure 1-2 The feeding port of the feeding pipe 3 is also covered with a dust cover 31, and the dust cover 31 is connected to the upper edge of the feeding pipe 3 by a hinge, so that the dust cover 31 can be rotated upward to open for easy feeding. When mixing raw materials, the dust cover 31 can be used to cover the feeding pipe 3 to reduce the possibility of dust intrusion.

[0028] See also Figure 1-2 The bin cover 2 and the mixing bin 1 are connected by a number of bolts, which makes it easy to disassemble the bin cover 2 and the mixing bin 1, and to open the bin cover 2 later to clean the inside of the mixing bin 1.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
