[0031] Reference Figures 1-5 , this example provides a selenium-rich feed production device with an efficient stirring structure, the purpose of which is to solve the problem that the existing selenium-rich feed is not fully mixed during stirring and mixing. The specific structure in this example will be elaborated in detail below.

[0032] A selenium-rich feed production device with an efficient stirring structure, which includes a stirring feed chamber 1, a stirring and mixing chamber 2, and a granulation machine 3.

[0033] Specifically, a first stirring mechanism 4 is arranged in the stirring feed chamber 1, and a second stirring mechanism 5 is arranged in the stirring and mixing chamber 2; the discharge port of the stirring feed chamber 1 is communicated with the feed port of the stirring and mixing chamber 2 through a first conveying mechanism 6; the discharge port of the stirring and mixing chamber 2 is communicated with the feed port of the granulation machine 3 through a second conveying mechanism 7.

[0034] Specifically, both the first conveying mechanism 6 and the second conveying mechanism 7 are screw conveyors.

[0035] In this example, a plurality of funnel-shaped feed ports are preset at the top of the stirring feed chamber 1. Different component raw materials of the selenium-rich feed can be fed into the stirring feed chamber 1 through the feed ports, and the first stirring mechanism 4 is used to initially stir the feed. The selenium-rich feed after the initial stirring falls from the bottom discharge port of the stirring feed chamber 1 into the first conveying mechanism 6 and is transported to the stirring and mixing chamber 2 through the first conveying mechanism 6. The selenium-rich feed after the initial stirring is stirred again in the stirring and mixing chamber 2, so as to achieve a highly sufficient mixing of each component of the selenium-rich feed through double stirring, improve the processing efficiency, and improve the uniformity of the selenium content after the feed is formed. Finally, it is transferred to the granulation machine 3 through the second conveying mechanism 7 for feed granulation, ensuring the uniformity of the selenium content of the formed selenium-rich feed and improving the product quality of the selenium-rich feed.

[0036] In this example, a screw conveyor is used for raw material transportation, realizing the automatic control of the production process, reducing the labor cost. At the same time, the raw materials can continue to roll during the transportation in the screw conveyor, further improving the stirring effect and efficiency.

[0037] Specifically, the first stirring mechanism 4 includes a first motor 41 disposed at the top of the stirring and feeding chamber 1. The output shaft of the first motor 41 passes through the top of the stirring and feeding chamber 1 and is provided with a first stirring rod 42.

[0041] The first stirring mechanism 4 includes a first motor 41 and a first stirring rod 42. The first motor 41 is installed at the top of the stirring and feeding chamber 1. The output shaft of the first motor 41 passes through the top plate of the stirring and feeding chamber 1 and is connected to the top end of the first stirring rod 42. A bearing seat 83 is provided at the bottom end of the first stirring rod 42. The bearing seat 83 is connected to the inner wall of the stirring and feeding chamber 1 through a plurality of support rods 84 in the circumferential direction, and the bearing seat 83 falls into the tapered bottom of the stirring and feeding chamber 1, so as to drive the first stirring rod 42 to rotate through the first motor 41.

[0042] An upper blade 43 is provided on the upper part of the first stirring rod 42, and a lower blade 44 is provided on the lower part of the first stirring rod 42. The length of the upper blade 43 fits the diameter of the stirring and feeding chamber 1. The lower blade 44 is located at the tapered bottom of the stirring and feeding chamber 1. Therefore, the blade length of the lower blade 44 gradually decreases to fit the tapered bottom of the stirring and feeding chamber 1. Furthermore, when the first motor 41 drives the first stirring rod 42 to rotate, the first stirring rod 42 drives the upper blade 43 and the lower blade 44 to rotate. The selenium-rich feed raw materials entering the stirring and feeding chamber 1 are initially broken and stirred by the upper blade 43 and the lower blade 44, so that the different component raw materials of the selenium-rich feed are preliminarily mixed.

A plurality of mounting grooves 46 are circumferentially provided in the middle of the first stirring rod 42.

In this embodiment, three transverse stirring mechanisms are provided, and the three transverse stirring mechanisms are evenly distributed in the circumferential direction of the middle part of the first stirring rod 42.

[0045] The transverse stirring mechanism includes a transverse stirring rod 45.

The other end of the transverse stirring rod 45 is provided with a transverse gear 48. The transverse gear 48 is embedded in the annular tooth groove 47 and meshed with each other. Thus, when the first stirring rod 42 rotates, it drives the three transverse stirring rods 45 to rotate synchronously in the circumferential direction. When the transverse stirring rod 45 rotates in the circumferential direction, it drives the transverse gear 48 to move in the annular tooth groove 47. Under the meshing action of the transverse gear 48 and the annular tooth groove 47, when the transverse stirring rod 45 is driven by the first stirring rod 42 to revolve, the transverse stirring rod 45 rotates itself. Stirring blades are evenly arranged on the transverse stirring rod 45, which can mix the raw material components of the selenium-rich feed in different horizontal planes when stirring the material. Furthermore, it forms a matching and counteracting stirring impact with the vertical stirring formed by the upper blade 43 and the lower blade 44, breaks and stirs the feed raw materials entering the stirring and feeding chamber 1, thereby realizing efficient stirring when the selenium-rich feed is fed, and further realizing the full mixing of the components of the selenium-rich feed.

[0047] Specifically, a transverse plate 21 is arranged at the top inside the stirring and mixing chamber 2. The transverse plate 21 and the top of the stirring and mixing chamber 2 form a gear cavity, and the transmission gear set is installed in the gear cavity; the end of the third stirring rod 53 passes through the transverse plate 21 and is installed at the top of the stirring and mixing chamber 2 through a bearing; the transmission gear set includes a driving gear 54 sleeved on the second stirring rod 52, and a plurality of driven gears 55 meshed with the driving gear 54; the plurality of driven gears 55 are respectively sleeved on the plurality of third stirring rods 53.

[0049] The second stirring mechanism 5 includes a second motor 51, a second stirring rod 52 and multiple third stirring rods 53. The second motor 51 is installed on the top of the stirring and mixing chamber 2. The output shaft of the second motor 51 passes through the top plate of the stirring and mixing chamber 2 and is connected to the top end of the second stirring rod 52. The bottom end of the second stirring rod 52 is provided with a second bearing bracket 82. The second bearing bracket 82 has the same structure as the first bearing bracket 81. Both support the bearing seat 83 at the bottom end of the second stirring rod 52 through multiple support rods 84, and position the bottom end of the second stirring rod 52 at the tapered bottom of the stirring and mixing chamber 2. Thus, the second motor 51 drives the second stirring rod 52 to rotate. While the second stirring rod 52 is rotating, the second stirring rod 52 drives multiple third stirring rods 53 to rotate through a transmission gear set. There are four third stirring rods 53 provided. The four third stirring rods 53 are evenly arranged around the circumference of the second stirring rod 52. Helical stirring blades are provided on both the second stirring rod 52 and the four third stirring rods 53. Thus, the selenium-rich feed entering the stirring and mixing chamber 2 is stirred. Through the second stirring rod 52 and the four third stirring rods 53, the feed raw materials can be stirred from multiple angles and at multiple levels, improving the stirring efficiency and uniformity, achieving efficient stirring of the selenium-rich feed, and further achieving full mixing of the components with different contents in the selenium-rich feed.

[0050] A gear cavity is formed at the top inside the stirring and mixing chamber 2 by a cross plate 21 at intervals. The transmission gear set is installed in the gear cavity. The second stirring rod 52 passes through the cross plate 21 through a bearing and is connected to the output shaft of the second motor 51. The four third stirring rods 53 pass through the cross plate 21 through bearings and are installed at the top inside the stirring and mixing chamber 2 through bearings. The transmission gear set includes a driving gear 54 and four driven gears 55. A driving gear 54 is sleeved on the second stirring rod 52. The four driven gears 55 are respectively sleeved on the four third stirring rods 53. And a driving gear 54 is respectively meshed and connected with the four driven gears 55. When the second stirring rod 52 rotates, it drives the driving gear 54 to rotate. The driving gear 54 drives the four driven gears 55 to rotate, driving the four third stirring rods 53 to rotate. Then, through the helical stirring blades on the second stirring rod 52 and the four third stirring rods 53, the selenium-rich feed entering the stirring and mixing chamber 2 is stirred, achieving stirring from multiple angles and at multiple levels, improving the stirring efficiency and uniformity, and achieving efficient stirring of the selenium-rich feed.

[0051] Specifically, a scraping mechanism 9 is provided on the inner wall of the stirring and mixing chamber 2; the scraping mechanism 9 includes two scraping plates 91 that fit the inner wall of the stirring and mixing chamber 2; the top ends of the two scraping plates 91 are embedded in a circular scraping groove 22 reserved on the cross plate 21; the bottom ends of the two scraping plates 91 are connected to the second stirring rod 52.

[0052] Specifically, arc-shaped scrapers 92 are provided on both sides of the scraper 91; a vertical plate scraper 93 is provided on one side of the scraper 91 away from the inner wall of the stirring and mixing chamber 2.

[0053] In this embodiment, a scraping mechanism 9 is provided on the inner wall of the stirring and mixing chamber 2. The raw materials adhered to the inner wall of the stirring and mixing chamber 2 are removed by the scraping mechanism 9. At the same time, the selenium-rich feed entering the stirring and mixing chamber 2 is stirred by the scraping mechanism 9 to cooperate with the second stirring rod 52 and the third stirring rod 53 to achieve multi-angle and multi-level stirring, improve the stirring efficiency and uniformity, and realize the efficient stirring when the selenium-rich feed is fed.

[0054] The scraping mechanism 9 includes two relatively arranged scrapers 91. The scrapers 91 are attached to the inner wall of the stirring and mixing chamber 2.

[0055] The bottom of the scraper 91 fits the tapered bottom of the stirring and mixing chamber 2. The lowest end of the scraper 91 is connected to the second stirring rod 52 through a connecting rod. When the second stirring rod 52 rotates, the two scrapers 91 are driven to rotate. Thus, the raw materials adhered to the inner wall of the stirring and mixing chamber 2 are removed by the arc-shaped scrapers 92 on the side of the scraper 91, and the selenium-rich feed is stirred in the circumferential direction of the stirring and mixing chamber 2 by the vertical plate scraper 93 to achieve the full mixing of the components of the selenium-rich feed.

[0056] The working principle of a selenium-rich feed production device with an efficient stirring structure in this solution is as follows:

[0057] In the practical application of the present invention, referring to Figures 1-5 , through the funnel-shaped feed inlet preset at the top of the stirring feed chamber 1, different component raw materials of the selenium-rich feed are fed into the stirring feed chamber 1. The first motor 41 drives the first stirring rod 42 to rotate. The first stirring rod 42 drives the upper blades 43 and the lower blades 44 to rotate. The upper blades 43 and the lower blades 44 are used to initially crush and stir the selenium-rich feed raw materials entering the stirring feed chamber 1. At the same time, the transverse stirring rod 45 rotates by itself, forming a matching and opposing stirring impact with the vertical stirring formed by the upper blades 43 and the lower blades 44 to crush and stir the feed raw materials entering the stirring feed chamber 1, thereby realizing the efficient stirring when the selenium-rich feed is fed, and further realizing the full mixing of the components of the selenium-rich feed, and initially mixing the different component raw materials of the selenium-rich feed.

[0058] The selenium-rich feed after the initial stirring falls from the bottom discharge port of the stirring feed chamber 1 into the first conveying mechanism 6 and is transported to the stirring and mixing chamber 2 through the first conveying mechanism 6.

[0059] In the stirring and mixing chamber 2, the second motor 51 drives the second stirring rod 52 to rotate. While the second stirring rod 52 is rotating, the second stirring rod 52 drives a plurality of third stirring rods 53 to rotate through a transmission gear set, so as to stir the selenium-rich feed entering the stirring and mixing chamber 2. At the same time, the scraping mechanism 9 is used to remove the raw materials adhering to the inner wall of the stirring and mixing chamber 2, and stir the selenium-rich feed in the circumferential direction of the stirring and mixing chamber 2, which can stir the feed raw materials from multiple angles and at multiple levels, improve the stirring efficiency and uniformity, realize the efficient stirring of the selenium-rich feed, and further realize the full mixing of each content component of the selenium-rich feed.

[0060] The selenium-rich feed after re-stirring falls from the bottom discharge port of the stirring and mixing chamber 2 into the second conveying mechanism 7, and is transported to the granulation machine 3 through the second conveying mechanism 7. The granulation machine 3 granulates the feed raw materials with highly mixed different components to prepare the formed selenium-rich feed with uniform selenium components.

[0061] Although the specific implementation manners of the invention have been described in detail with reference to the accompanying drawings, it should not be construed as a limitation on the protection scope of this patent. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative efforts still fall within the protection scope of this patent.
