Description

Technical Field

[0001] The utility model relates to the technical field of glucosamine granule drying, in particular to a drying device for processing glucosamine granules. Background Art

[0002] Glucosamine is an important nutritional health product and pharmaceutical raw material, which is transformed through the reaction of bone powder and yeast. Then, the fermentation broth is filtered and concentrated to separate the suspended matter and liquid in the fermentation broth to obtain pure glucosamine. Next, the glucosamine is further purified through ion exchange and ultrafiltration technologies. After purification, there is still a certain amount of moisture remaining on the surface of the glucosamine granules, and a special drying device is required to dry the glucosamine granules, which is beneficial to the long-term storage of the glucosamine granules. However, the existing drying devices for processing glucosamine granules generally have the following technical problems during drying:

[0003] When the glucosamine granules are dried in a stirring cylinder or a drying tank, there is a problem that the glucosamine granules are not in sufficient contact with the hot air flow during drying, which may affect the drying efficiency of the glucosamine granules;

[0004] Based on this, a drying device for processing glucosamine granules that can solve the above problems is proposed. Content of the Utility Model

[0005] To solve the technical problems of drying glucosamine granules, the utility model provides a drying device for processing glucosamine granules.

[0006] The utility model is realized by adopting the following technical solutions: A drying device for processing glucosamine granules includes a furnace body. A plurality of outer flow furnace beds and inner flow furnace beds are fixedly connected inside the furnace body. The plurality of outer flow furnace beds and inner flow furnace beds are alternately and equidistantly distributed along the inner wall of the furnace body in sequence. The upper surfaces of each of the outer flow furnace beds and inner flow furnace beds can dry the glucosamine granules. A plurality of outer leakage ports are opened on the outer edges of each of the outer flow furnace beds. Circular inner leakage ports are opened at the central positions of each of the inner flow furnace beds. An installation frame is fixedly connected to the lower side of the furnace body. A feed pipe is communicated with the upper side of the furnace body. A discharge port is opened at the bottom side of the furnace body. A rake-type transfer mechanism for making the glucosamine granules migrate layer by layer and alternately inside and outside from the upper furnace bed to the lower furnace bed is arranged on the upper sides of each of the outer flow furnace beds and inner flow furnace beds. An electric heating mechanism for heating and drying the entire furnace body is arranged inside the furnace body. An air circulation mechanism for accelerating the air flow inside the furnace body is arranged outside the furnace body.

[0007] As a further improvement of the above solution, the rake-type transfer mechanism includes a servo motor fixedly connected to the lower side of the furnace body. The output end of the servo motor is fixedly connected with a hollow shaft. A plurality of rake arms are fixedly connected to the outer side of the hollow shaft at each layer of the furnace bed. The plurality of rake arms at each layer are distributed in a circumferential array. The inside of the hollow shaft is a hollow structure. The hollow shaft is rotatably connected to each outer-flow furnace bed. The hollow shaft passes through each inner-flow furnace bed through the center of the inner leakage opening. An outer-scraping mechanism for migrating the glucosamine particles on the furnace bed from the inside to the outside is arranged on the outer side of the hollow shaft at each outer-flow furnace bed. An inner-scraping mechanism for migrating the glucosamine particles on the furnace bed from the outside to the inside is arranged on the outer side of the hollow shaft at each inner-flow furnace bed.

[0008] As a further improvement of the above solution, the outer-scraping mechanism includes a plurality of outer-pushing rake teeth arranged above each outer-flow furnace bed. Each of the outer-pushing rake teeth is fixedly connected to the lower side of each rake arm at the same layer.

[0009] As a further improvement of the above solution, the inner-scraping mechanism includes a plurality of inner-scraping rake teeth arranged above each inner-flow furnace bed. Each of the inner-scraping rake teeth is fixedly connected to the lower side of each rake arm at the same layer.

[0010] As a further improvement of the above solution, the electric heating mechanism is an electric heating rod arranged inside the hollow shaft.

[0011] As a further improvement of the above solution, the air circulation mechanism includes a blower communicated with the outer side of the furnace body. A flue gas exhaust port is opened on the upper side of the furnace body. A baffle is arranged above the flue gas exhaust port. A plurality of connecting rods are fixedly connected between the baffle and the upper side of the furnace body. A limiting ring is fixedly connected together inside the plurality of connecting rods. The limiting ring is rotatably connected to the upper end of the hollow shaft.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By arranging an outer leakage opening on the outer-flow furnace bed and an inner leakage opening on the inner-flow furnace bed in the present utility model, when the rake-type transfer mechanism migrates the glucosamine particles from top to bottom, at this time, the hot air flow with a higher temperature rises due to the principle of thermal expansion and contraction. Under the pushing action of the air circulation mechanism, the hot air contacts the glucosamine particles that are falling in the inner leakage opening and the outer leakage opening, realizing a more sufficient drying effect.

[0014] 2. The utility model uses a rake transfer mechanism to move the glucosamine particles on the upper layer downward alternately and step by step through the inner rake teeth and the outer rake teeth. The inner rake teeth and the outer rake teeth not only push the glucosamine particles on each layer of the furnace bed, but also stir the particles to expand the heat dissipation area. In addition, the inner and outer spreading migration effect on the furnace beds at each level blocks the outflow time of the glucosamine particles, which increases the drying time of the glucosamine particles on the furnace beds at each layer of the furnace body in disguised form. At the same time, due to the higher temperature of each layer of the furnace bed, the drying efficiency is further improved through full contact with the glucosamine particles.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example:

[0023] Please combine Figure 1 - Figure 4, A drying device for processing glucosamine granules in this embodiment includes a furnace body 3. Inside the furnace body 3, two outer flow furnace beds 13 and an inner flow furnace bed 14 are fixedly connected. The two outer flow furnace beds 13 and the inner flow furnace bed 14 are alternately and equidistantly distributed along the inner wall of the furnace body 3 in sequence. The upper surfaces of each outer flow furnace bed 13 and the inner flow furnace bed 14 can dry the glucosamine granules. A plurality of outer leakage ports 15 are opened on the outer side of the edge of each outer flow furnace bed 13, and a circular inner leakage port 16 is opened at the central position of each inner flow furnace bed 14. An installation frame 1 is fixedly connected to the lower side of the furnace body 3. A feed pipe 5 is communicated with the upper side of the furnace body 3, and a discharge port 11 is opened at the bottom side of the furnace body 3. On the upper side of each outer flow furnace bed 13 and the inner flow furnace bed 14, a rake-type transfer mechanism is provided to make the glucosamine granules migrate layer by layer and alternately inside and outside from the upper furnace bed to the lower furnace bed. An electric heating mechanism for heating and drying the entire furnace body is arranged inside the furnace body 3, and an air circulation mechanism for accelerating the air flow inside the furnace body 3 is arranged outside the furnace body 3.

[0024] Please refer to Figure 2 As shown, the rake-type transfer mechanism includes a servo motor 2 fixedly connected to the lower side of the furnace body 3. The output end of the servo motor 2 is fixedly connected with a hollow shaft 6. Three rake arms 12 are fixedly connected to the outer side of the hollow shaft 6 at each furnace bed. The three rake arms 12 of each layer are distributed in a circular array. The inside of the hollow shaft 6 is a hollow structure. The hollow shaft 6 is rotatably connected to each outer flow furnace bed 13, and the hollow shaft 6 passes through each inner flow furnace bed 14 through the center of the inner leakage port 16. An outer sweeping mechanism for migrating the glucosamine granules on the furnace bed from the inside to the outside is arranged on the outer side of the hollow shaft 6 at each outer flow furnace bed 13, and an inner scooping mechanism for migrating the glucosamine granules on the furnace bed from the outside to the inside is arranged on the outer side of the hollow shaft 6 at each inner flow furnace bed 14.

[0025] The outer sweeping mechanism includes a plurality of outer pushing rake teeth 18 arranged above each outer flow furnace bed 13. Each outer pushing rake tooth 18 is fixedly connected to the lower side of each rake arm 12 of the same layer.

[0026] The inner scooping mechanism includes a plurality of inner scooping rake teeth 17 arranged above each inner flow furnace bed 14. Each inner scooping rake tooth 17 is fixedly connected to the lower side of each rake arm 12 of the same layer.

[0027] It should be particularly noted that considering that when the inner scooping rake teeth 17 and the outer pushing rake teeth 18 rotate along each furnace bed, if the distance between the rake teeth and the furnace bed is too large, it may damage the structure of the granules. At this time, a flexible cleaning brush mechanism can be added to the side of each inner scooping rake tooth 17 and the outer pushing rake tooth 18 close to the furnace bed surface, which can not only clean the granules cleanly but also not damage the granule structure.

[0028] Please refer to Figure 2 As shown, the electric heating mechanism is an electric heating rod 19 arranged inside the hollow shaft 6.

[0029] Please refer to Figure 1 As shown, the air circulation mechanism includes a blower 4 communicating with the outside of the furnace body 3. A flue gas exhaust port 10 is provided on the upper side of the furnace body 3. A baffle 7 is arranged above the flue gas exhaust port 10. Four connecting rods 9 are fixedly connected between the baffle 7 and the upper side of the furnace body 3. An inner limiting ring 8 is fixedly connected to the inner sides of the four connecting rods 9 together. The inner limiting ring 8 is rotatably connected to the upper end of the hollow shaft 6.

[0030] The implementation principle of a drying device for processing glucosamine granules in the embodiment of the present application is as follows: The staff feeds the glucosamine granules into the furnace body 3 from the feed pipe 5. When the servo motor 2 starts, it drives the hollow shaft 6 to rotate. The rotation of the hollow shaft 6 drives the rake arms 12 above the outer flow furnace beds 13 and the inner flow furnace beds 14 to rotate. Assuming the hollow shaft 6 rotates clockwise, the inner rake teeth 17 can rake the glucosamine granules on the inner flow furnace bed 14 into the inner leakage port 16 and fall to the next layer. Similarly, because the outer pushing rake teeth 18 have a structure opposite to that of the inner rake teeth 17, when the hollow shaft 6 rotates clockwise, the outer pushing rake teeth 18 can sweep the glucosamine granules on the outer flow furnace bed 13 into the outer leakage port 15 at the edge and fall onto the next layer of the furnace bed. The electric heating rods 19 arranged on the hollow shaft 6 can heat the air in the furnace body 3. The heated and expanded air, with the assistance of the blower 4, flows upward through the inner leakage ports 16 and the outer leakage ports 15 in sequence, achieving the effect of drying the granules. The impurities formed by the gas are discharged from the flue gas exhaust port 10.

[0031] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
