Description

Technical Field

[0001] The invention belongs to the technical field of feed processing, and in particular relates to a nucleotide feed high-efficiency energy-saving pulverizing device and a pulverizing method. Background Art

[0002] Nucleotide feed is a functional feed additive. As the basic structural unit of nucleic acid, nucleotide plays many important roles in animals. It participates in the life activities of all cells in the body and has an important impact on the animal's immune system, gastrointestinal development, liver function and lipid metabolism. Nucleotide feed can promote animal growth and improve meat quality. It is a semi-essential nutrient and is of great significance to the healthy breeding of livestock, poultry and aquatic animals.

[0003] A double-crushing feed crushing device with publication number CN108325690A discloses a double-crushing feed crushing device, including a crushing box, two pairs of crushing rollers are arranged inside the crushing box, a feed inlet is arranged on the top wall of the crushing box, two grinding screens are arranged inside the crushing box, the two grinding screens are fixedly connected at the near end, a vertical screw shaft is also arranged inside the crushing box, grinding pressure plates are arranged on the two grinding screens, the lower end of the screw shaft is connected to the transmission horizontal shaft through a gear mechanism, a driving gear is also arranged on the transmission horizontal shaft, the driving gear is meshed with two transmission gears arranged on two rotating horizontal shafts, a knocking rod is also arranged on the two rotating horizontal shafts, and a knocking block is also arranged at the outer end of the knocking rod.

[0015] The moisture removal mechanism also includes a support frame, and a plurality of the hot air blower components are equidistantly arranged and hinged on the support frame, and can swing to blow hot air comprehensively onto the surface of the nucleotide feed on the screen.

[0041] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See also Figure 1-Figure 9The present application provides an energy-efficient pulverizing device and a pulverizing method for nucleotide feed, comprising a pulverizing box 1 and a pulverizing roller assembly 5 arranged inside the pulverizing box 1. The pulverizing roller assembly 5 is a prior art that can be driven by a motor to pulverize the nucleotide feed, and a partition 9 is fixedly installed on the inner wall of the pulverizing box 1. A screening mechanism 4 is installed below the pulverizing roller assembly 5. The screening mechanism 4 includes a screen 41 that is arranged obliquely and hinged on the partition 9, and the height of one end of the screen 41 close to the partition 9 is lower than the height of the other end of the screen 41. It should be noted that the screen 41 only needs to be slightly tilted, as long as it can ensure that the nucleotide feed can roll on the screen 41 through the partition 9 and enter the area of ​​the feeding mechanism 8. A motor seat 42 is fixedly installed on the side wall of the screen 41, and a No. 1 drive motor 43 is fixedly installed on the motor seat 42. A stirring assembly 44 is installed on the screen 41, and the stirring assembly 4 4 comprises a plurality of stirring rods 441 which are equidistantly arranged and rotatably mounted on the screen 41, the plurality of stirring rods 441 are connected by a No. 1 transmission assembly 442, and the No. 1 transmission assembly 442 is composed of two pulleys and a belt connecting the two pulleys, the output end of the No. 1 driving motor 43 is fixedly mounted to the end of any one of the stirring rods 441, the screen 41 is also mounted with a vibration assembly 45, the vibration assembly 45 comprises a No. 1 rotating shaft 451 rotatably mounted on the screen 41, a semicircular counterweight block 452 is fixedly mounted at both ends of the No. 1 rotating shaft 451, and the end of the No. 1 rotating shaft 451 is connected to the nearest stirring rod 441 through a No. 2 transmission assembly 453 for transmission, and a support block 46 is also fixedly mounted on the inner wall of the crushing box 1, and a No. 1 return spring 47 is mounted on the support block 46, and the No. 1 return spring 47 is used to increase the vibration effect of the screen 41.

[0044] Specifically, after the nucleotide feed is initially crushed by the crushing roller assembly 5, it falls into the area of ​​the screening mechanism 4, and the No. 1 driving motor 43 is started to drive one of the stirring rods 441 to rotate. The stirring rod 441 drives the remaining stirring rods 441 to rotate through the No. 1 transmission assembly 442 to break up the nucleotide feed that falls into the screen 41 to prevent excessive moisture from condensing together. The rotation of the stirring rod 441 drives the No. 1 rotating shaft 451 to rotate through the No. 2 transmission assembly 453, and the No. 1 rotating shaft 451 drives the semicircular counterweight block 452 to rotate. Since the semicircular counterweight block 452 is semicircular as a whole, the center of gravity changes continuously during the rotation process, causing the end of the screen 41 away from the partition 9 to shake up and down continuously, and under the action of the No. 1 reset spring 47, the small-diameter feed is screened and dropped from the screen 41, while the large-diameter nucleotide feed remains on the screen 41. The stirring rod 441 is used to break up the nucleotide feeds that are condensed together due to the presence of water, and the small-diameter nucleotide feeds are also screened out by the screen 41, so that the nucleotide feeds that remain above the screen 41 are all large-diameter nucleotide feeds, and are transported to the crushing roller assembly 5 through the feeding mechanism 8 for further crushing. At this point, before the nucleotide feeds are crushed multiple times, the small-diameter nucleotide feeds that meet the standards are first separated, and the large-diameter nucleotide feeds are crushed again, changing the original method of directly passing all the nucleotide feeds of all diameters through the crushing roller assembly 5 for secondary crushing. On the one hand, the small-diameter nucleotide feeds will become smaller again due to the crushing of the crushing roller assembly 5, resulting in uneven particle size of the obtained nucleotide feeds. On the other hand, the crushing of the nucleotide feeds that meet the standards through the crushing roller assembly 5 again will increase the burden of the crushing roller assembly 5, resulting in a waste of resources.

[0045] In this embodiment, a slope 13 is provided at the bottom of the crushing box 1 to facilitate the nucleotide feed that meets the standards to roll out from the feed port 12 and be collected.

[0046] Embodiment 2:

[0047] On the basis of the first embodiment, a moisture removal mechanism 6 is installed on the screening mechanism 4, and the moisture removal mechanism 6 includes a support frame 61 fixedly installed on the screen 41 and a second drive motor 62, and a rotating disc 63 is fixedly installed at the output end of the second drive motor 62, and an eccentric shaft 64 is eccentrically connected to the rotating disc 63, and a connecting rod 65 is rotatably connected to the eccentric shaft 64, and the end of the connecting rod 65 away from the eccentric shaft 64 is rotatably connected to the connecting shaft 66, and a plurality of hot air blower assemblies arranged equidistantly are hinged on the support frame 61 610. It should be noted here that the hot air blower assembly 610 is a prior art, which can blow out fine hot air, and can evaporate part of the moisture in the nucleotide feed on the screen 41 so that it does not stick together. The lower end of each hot air blower assembly 610 is fixedly connected to a fixed shaft 69, and the lower ends of multiple fixed shafts 69 are commonly fixedly installed with a No. 1 connecting plate 68. A No. 1 connecting block 67 is fixedly installed on the bottom wall of the No. 1 connecting plate 68, and the connecting shaft 66 is fixedly installed on the No. 1 connecting block 67.

[0048] Specifically, the rotating disk 63 is driven to rotate by starting the No. 2 driving motor 62, and the rotating disk 63 drives the eccentric shaft 64 thereon to rotate, and the eccentric shaft 64 drives the connecting rod 65 to move, and then the No. 1 connecting block 67 is driven to move up and down by pulling the connecting shaft 66, and the No. 1 connecting block 67 drives the No. 1 connecting plate 68 to reciprocate up and down, and then the hot air blower assembly 610 connected thereto is driven by multiple fixed shafts 69 to slowly swing to blow hot air onto the nucleotide feed on the screen 41. Because the agglomerated nucleotide feed is large, it will be blocked by the blades on the stirring rod 441 and will not pass through the partition 9 to enter the area of ​​the feeding mechanism 8. Therefore, it can be combined with the moisture removal mechanism 6 to evaporate the moisture inside the nucleotide feed, so that the agglomerated nucleotide feed becomes loose, which is conducive to the stirring rod 441 to break the agglomerated nucleotide feed, and then the multiple hot air blower assemblies 610 are continuously swung, so that the nucleotide feed away from the moisture removal mechanism 6 can also be blown by the hot air, thereby improving the uniformity of the hot blowing.

[0049] Embodiment three:

[0050] On the basis of the second embodiment, a feeding mechanism 8 is further installed inside the crushing box 1, and the feeding mechanism 8 includes a feeding seat 81 arranged between two partitions 9, a magnetic slider 82 is arranged on the feeding seat 81, and an electromagnetic guide rail used in conjunction with the magnetic slider 82 is arranged on the inner wall of the crushing box 1. When powered on, the magnetic slider 82 can slide up and down inside the electromagnetic guide rail, thereby driving the feeding seat 81 to slide up and down, a fixing pin 83 is fixedly installed on the feeding seat 81, a cable 86 is fixedly installed on the fixing pin 83, and a baffle 89 is fixedly installed on the end of the cable 86 away from the fixing pin 83, and a slide groove 91 is arranged on the partition 9, the baffle 89 is slidably installed inside the slide groove 91, and a cable 86 for making the baffle 89 slide inside the slide groove 91 is installed inside the slide groove 91. The plate 89 is reset by a No. 2 return spring 810. The partition 9 is also provided with a feed window 92 which is connected with the slide groove 91, so as to allow the nucleotide feed with a larger diameter to fall into the area of ​​the feeding mechanism 8. The feeding mechanism 8 also includes a No. 2 rotating shaft 84 rotatably mounted on the inner wall of the crushing box 1. The No. 2 rotating shaft 84 is fixedly mounted with a steering pulley 85 for steering the cable 86, and part of the cable 86 is attached to the steering pulley 85. A fixed seat 87 is fixedly mounted on the partition 9, and two anti-wear pulleys 88 arranged in parallel are rotatably mounted on the fixed seat 87. The cable 86 passes between the two anti-wear pulleys 88 to avoid contact with the upper wall of the partition 9 and reduce the wear of the cable 86. The cable 86 passes through the interior of the partition 9.

[0051] Specifically, when the larger-caliber nucleotide feed passes through the feed window 92 on the partition 9 and falls and accumulates on the feed seat 81, the larger-caliber nucleotide feed is transported to the crushing roller assembly 5 for crushing again under the action of the magnetic slider 82 and the magnetic guide rail, and the top surface of the feed seat 81 is arranged in an inclined manner to enable the nucleotide feed to slide from the feed seat 81 to the feed seat 81 without accumulating and remaining on the feed seat 81. During the rising process of the feed seat 81, the cable 86 is changed from the originally taut state to the relaxed state, so that the baffle 89 is released under the action of the No. 2 return spring 810. The baffle plate 89 is pushed from the inside of the slide groove 91 to the area of ​​the feed window 92 to temporarily block the feed window 92. It should be noted that the elastic force of the No. 2 return spring 810 can maintain the push of the baffle plate 89 until the feed window 92 is blocked, and the feed window 92 is completely blocked before the feeding seat 81 reaches the same height as the feed window 92, thereby avoiding the problem that the nucleotide feed on the screen 41 continues to be transported to the area of ​​the feeding mechanism 8, resulting in the feed not falling onto the feeding seat 81 but falling onto the bottom inner wall of the crushing box 1, causing waste of nucleotide feed.

[0052] In this embodiment, a guide plate 10 is fixedly mounted on the partition 9 in an inclined manner. The guide plate 10 is mounted on the side of the partition 9 close to the crushing roller assembly 5. The setting of the guide plate 10 enables the nucleotide feed transported by the feeding mechanism 8 to first pass through the guide plate 10 and then fall onto the crushing roller assembly 5. It can be guided by the guide plate 10 to fall into the gap between the two crushing roller assemblies 5, thereby improving the crushing efficiency.

[0053] Embodiment 4:

[0054] On the basis of Example 3, a feed port 12 is provided through the upper end of the crushing box 1, and an anti-blocking mechanism 7 is provided above the feed port 12. The anti-blocking mechanism 7 includes a cylinder 71 fixedly installed on the top surface of the crushing box 1, and a No. 2 connecting block 72 is fixedly installed on the output end of the cylinder 71, and a No. 2 connecting plate 73 is fixedly installed on the No. 2 connecting block 72. The No. 2 connecting plate 73 is provided with two means for pushing the nucleotide feed piled in the feed port 12 into the interior of the crushing box 1 to prevent it from being blocked inside the feed port 12.

[0055] Embodiment five:

[0056] Based on the fourth embodiment, a nucleotide feed high-efficiency and energy-saving crushing method comprises the following steps:

[0057] S1, pouring the nucleotide feed from the feed port 12 into the inside of the crushing box 1, and at the same time, unblocking the feed port 12 by moving the anti-blocking push rod 74 up and down, and then performing the initial crushing by the crushing roller assembly 5, the crushed feed falls onto the screen 41 and the small-diameter nucleotide feed is separated by the screen 41;

[0058] S2, the feed agglomerated on the screen 41 is evaporated and dehydrated by the water removal mechanism 6 to make it loose, and at the same time, the stirring rod 441 rotates to break up the feed agglomerated by water, so that the small-caliber feed can be smoothly screened out;

[0059] S3. After screening, the large-diameter feed intercepted by the screen 41 falls onto the feeding seat 81, and the feed is transported to the crushing roller assembly 5 through the feeding seat 81 for secondary crushing.

[0060] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
