Description
Technical Field
[0001] This utility model belongs to the field of shell powder production technology, specifically a layered dryer for shell powder production. Background Technology
[0002] Shell powder is a powdery substance made from oysters, freshwater mussels, clams, and other shells through cleaning, crushing, and grinding. Its main component is calcium carbonate, and its natural porous fibrous double helix structure gives it unique adsorption properties. It is widely used in environmentally friendly building materials, agriculture, industry, and other fields.
[0003] During the production and processing of shell powder, the shells retain moisture after washing, resulting in a significant amount of residual moisture in the semi-finished shell powder. Therefore, it is necessary to dry the semi-finished shell powder. Through long-term observation, it has been found that the existing shell powder drying methods are usually carried out in drying rooms or tunnel dryers. However, in this method, the shell powder is in a piled-up state, which easily leads to uneven heating of the shell powder and affects the drying effect.
[0004] Therefore, this utility model provides a layered dryer for the production of seashell powder. Summary of the Invention
[0005] To overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a layered dryer for shell powder production is proposed.

Through the above structure, the rotating shaft, pusher plates, and material trays are set, and the discharge port, electric heating tubes, and feeding bin are coordinated to dry the shell powder in layers through multiple material trays. When the pusher plates rotate, they can continuously turn the shell powder, thereby improving the uniformity of drying the shell powder and reducing the uneven drying caused by the large thickness of the shell powder piled up during drying in the traditional method.
[0007] Preferably, a spring is fixedly connected to the side wall of the support leg; a sieve box is fixedly connected to the end of the spring; the bottom of the sieve box has a mesh structure; and a vibration motor is fixedly connected to the side wall of the sieve box. With the above structure, the spring, sieve box, and vibration motor can be used to sieve the dried seashell powder, thereby reducing the possibility of large particles in the seashell powder affecting the quality of the finished product, improving the uniformity of the finished seashell powder, and enhancing the overall functionality of the device.
[0008] Preferably, a fixing rod is fixedly connected to the bottom of the rotating shaft; a pair of scrapers are fixedly connected to the end of the fixing rod; the pair of scrapers are symmetrical; the scrapers are located inside the feeding hopper; with the above structure, the fixing rod and scrapers can be set so that the inner wall of the feeding hopper can be continuously scraped by the scrapers to reduce the situation where shell powder adheres to the inner wall of the feeding hopper during the feeding process, which would make it difficult to collect and cause waste.
[0009] Preferably, a fixing frame is fixedly connected to the top of the drying tank; an exhaust fan is installed inside the fixing frame; the exhaust fan is arranged correspondingly to the exhaust port; through the above structure, the fixing frame and the exhaust fan can continuously draw air from the inside of the drying tank to increase the speed of steam flowing from the inside of the drying tank to the outside, so as to reduce the situation where steam re-condenses into water droplets inside the drying tank, thus affecting the drying effect of the shell powder.
[0010] Preferably, a plurality of shields are fixedly connected to the middle of the rotating shaft; the top of the shield is a conical structure; the bottom of the shield is in contact with the material tray; through the above structure, the shields are connected to the rotating shaft, which can reduce the occurrence of shell powder falling into the connection position between the material tray and the rotating shaft, thus preventing the rotating shaft and the material tray from getting stuck.
[0011] Preferably, a plurality of ball bearings are installed on the inner wall of the material tray; the plurality of ball bearings are evenly distributed on the inner wall of the material tray; through the above structure, the ball bearings can reduce the friction between the rotating shaft and the inner wall of the material tray, thereby reducing damage caused by excessive friction.

Detailed Implementation
[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 4As shown in the embodiment of this utility model, the layered dryer for producing shell powder includes a drying tank 1; a feed inlet 11 is installed on the top of the drying tank 1; a motor body 12 is fixedly connected to the top of the drying tank 1; a rotating shaft 13 is fixedly connected to the output end of the motor body 12; multiple pusher plates 14 are fixedly connected to the middle of the rotating shaft 13; multiple material trays 15 are fixedly connected to the inner side wall of the drying tank 1; the pusher plates 14 are correspondingly arranged with the material trays 15; a discharge port 16 is opened in the middle of the pusher plates 14; multiple electric heating tubes 17 are installed at the bottom of the pusher plates 14; a discharge bin 18 is installed at the bottom of the drying tank 1; multiple support legs 19 are fixedly connected to the side wall of the drying tank 1; and an exhaust port 110 is opened at the top of the drying tank 1. During operation, when drying the shell powder, the shell powder can be added from the feed inlet 11, and then the shell powder will fall into the material tray 15 on the top layer. At the same time, the electric heating tubes 17 are energized to heat up and dry the shell powder in the material tray 15. At this time, the electric heating tubes 17 can be started. The machine body 12 drives the rotating shaft 13 to rotate. At this time, the rotating shaft 13 drives the pusher plate 14 to rotate in the material tray 15, which can continuously push the shell powder in the material tray 15 to rotate. When the shell powder passes through the discharge port 16, it will fall downwards. The discharge ports 16 in the middle of the multi-layer material tray 15 are staggered, so that the shell powder on the top layer falls into the second layer. Then, the pusher plate 14 in the second layer pushes the shell powder from the discharge port 16 into the bottom layer. After being dried layer by layer, the shell powder enters the feeding hopper 18 from the discharge port 16 of the bottom layer and is then discharged into the drying tank 1. Through the above structure, the rotating shaft 13, the pusher plate 14 and the material tray 15 are set up, and the discharge port 16, the heating tube 17 and the feeding hopper 18 are matched. The shell powder can be dried in layers through the multi-layer material tray 15. When the pusher plate 14 rotates, it can continuously turn the shell powder, thereby improving the uniformity of drying the shell powder and reducing the situation where the shell powder is piled up and dried in the traditional way, which leads to uneven drying due to the large thickness.
[0025] like Figure 1 As shown, a spring 2 is fixedly connected to the side wall of the support leg 19; a sieve box 21 is fixedly connected to the end of the spring 2; the bottom of the sieve box 21 has a mesh structure; a vibration motor 22 is fixedly connected to the side wall of the sieve box 21; during operation, when the shell powder is discharged from the feed hopper 18, it will fall into the sieve box 21, and then the collection container is placed below the sieve box 21. At this time, the vibration motor 22 can be started to drive the sieve box 21 to shake continuously, thereby screening the shell powder entering the sieve box 21 and separating larger particles. Through the above structure, with the spring 2, sieve box 21 and vibration motor 22, the dried shell powder can be screened to reduce the situation where the shell powder contains large particles that affect the quality of the finished product, thereby improving the uniformity of the finished shell powder and improving the overall functionality of the device.
[0026] like Figure 3As shown, a fixed rod 3 is fixedly connected to the bottom of the rotating shaft 13; a pair of scrapers 31 are fixedly connected to the end of the fixed rod 3; the pair of scrapers 31 are symmetrical; the scrapers 31 are located inside the feeding bin 18; during operation, when the rotating shaft 13 rotates, it will drive the fixed rod 3 and the scrapers 31 to rotate. At this time, the scrapers 31 rotate on the inner wall of the feeding bin 18, and can continuously scrape the inner wall of the feeding bin 18. When the shell powder adheres to the inner wall of the feeding bin 18 during the discharge process, it will be continuously scraped off by the scrapers 31. Through the above structure, the fixed rod 3 and the scrapers 31 are set, and the inner wall of the feeding bin 18 can be continuously scraped by the scrapers 31 to reduce the situation where the shell powder adheres to the inner wall of the feeding bin 18 during the discharge process, which leads to difficulty in collection and waste.
[0027] like Figure 2 As shown, a fixed frame 4 is fixedly connected to the top of the drying tank 1; an exhaust fan 41 is installed inside the fixed frame 4; the exhaust fan 41 is correspondingly arranged with the exhaust port 110; during operation, a large amount of steam is generated when drying the shell powder. When the steam rises, it will be discharged from the exhaust port 110. At this time, the exhaust fan 41 can be started to rotate, thereby driving the airflow from the inside of the drying tank 1 to the exhaust port 110. At this time, the exhaust fan 41 can draw air from the inside of the drying tank 1. Through the above structure, with the fixed frame 4 and the exhaust fan 41, the exhaust fan 41 can continuously draw air from the inside of the drying tank 1 to increase the speed of steam flowing from the inside of the drying tank 1 to the outside, thereby reducing the situation where the steam re-condenses into water droplets inside the drying tank 1, which would affect the drying effect of the shell powder.
[0028] like Figure 3 and Figure 5 As shown, multiple shields 5 are fixedly connected to the middle of the rotating shaft 13; the top of the shield 5 is a conical structure; the bottom of the shield 5 is in contact with the material tray 15; during operation, when the pusher plate 14 rotates, it will drive the shield 5 to rotate. At this time, the shield 5 covers the position where the material tray 15 contacts the rotating shaft 13. When the shell powder falls to the connection position between the material tray 15 and the rotating shaft 13, it will be blocked by the shield 5 and fall back into the middle of the material tray 15. Through the above structure, by setting the shield 5 to connect the rotating shaft 13, the amount of shell powder falling into the connection position between the material tray 15 and the rotating shaft 13 can be reduced, which may cause the rotating shaft 13 and the material tray 15 to get stuck.
[0029] like Figure 5 As shown, a plurality of balls 6 are installed on the inner wall of the material tray 15; the plurality of balls 6 are evenly distributed on the inner wall of the material tray 15; during operation, when the rotating shaft 13 rotates and its surface contacts the balls 6, the balls 6 will convert the sliding friction between the rotating shaft 13 and the material tray 15 into rolling friction. Through the above structure, the balls 6 can reduce the friction between the rotating shaft 13 and the inner wall of the material tray 15, so as to reduce the damage caused by excessive friction.
[0030] like Figure 2 As shown, a protective net 7 is fixed between each of the two adjacent material trays 15; the protective net 7 is set close to the outside of the material tray 15; during operation, when the shell powder falls between the multi-layer material trays 15, dust will be generated and scattered. At this time, the protective net 7 is located outside the adjacent material trays 15, which can block the generated dust. Through the above structure, the protective net 7 is set to close the adjacent material trays 15, which can reduce the dust generated when the shell powder falls between the material trays 15 and be scattered to the outside.
[0031] Working principle: When drying seashell powder, the seashell powder can be added through the feed inlet 11, and then the seashell powder will fall into the top tray 15. At the same time, the heating element 17 is energized to heat the seashell powder in the tray 15 to dry it. At this time, the motor body 12 can be started to drive the rotating shaft 13 to rotate. The rotating shaft 13 drives the pusher plate 14 to rotate in the tray 15, which can continuously push the seashell powder in the tray 15 to rotate. When the seashell powder passes through the discharge port 16, it will fall downwards. The discharge ports 16 in the middle of the multi-layer tray 15 are staggered, so that the top layer of seashell powder will fall downwards. The powder falls into the second layer, and then the pusher plate 14 in the second layer pushes the shell powder from the outlet 16 into the bottom layer. After being dried layer by layer, the shell powder enters the feeding hopper 18 from the bottom outlet 16 and then exits into the drying tank 1. When the shell powder is discharged from the feeding hopper 18, it falls into the sieve box 21. Then, the collection container is placed below the sieve box 21. At this time, the vibrating motor 22 can be started to drive the sieve box 21 to shake continuously, thereby screening the shell powder entering the sieve box 21 and separating larger particles. When the rotating shaft 13 rotates, it will drive the fixed Rod 3 and scraper 31 rotate. At this time, scraper 31 rotates on the inner wall of the feeding hopper 18, continuously scraping the inner wall of the feeding hopper 18. When the shell powder adheres to the inner wall of the feeding hopper 18 during the discharge process, it will be continuously scraped off by scraper 31. A large amount of steam is generated when drying the shell powder. When the steam rises, it will be discharged from the exhaust port 110. At this time, the exhaust fan 41 can be started to rotate, thereby driving the airflow from the inside of the drying tank 1 to the exhaust port 110. At this time, the exhaust fan 41 can be used to draw air from the inside of the drying tank 1. When the pusher plate 14 rotates... When the shield 5 rotates, it covers the position where the material tray 15 contacts the rotating shaft 13. When the shell powder falls to the connection between the material tray 15 and the rotating shaft 13, it will be blocked by the shield 5 and fall back into the middle of the material tray 15. When the rotating shaft 13 rotates, its surface contacts the ball bearing 6. At this time, the ball bearing 6 will change the sliding friction between the rotating shaft 13 and the material tray 15 into rolling friction. When the shell powder falls between the multiple material trays 15, dust will be generated. At this time, the protective net 7 is located outside the adjacent material tray 15 and can block the generated dust.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
