Description

Technical Field

[0001] This application relates to the technical field of feed screening devices, and more particularly to a pellet feed screening device. Background Technology

[0002] Pelleted feed is a regular granular feed product made from various feed ingredients (such as grains, protein ingredients, minerals, vitamins, etc.) through processes such as crushing, mixing, conditioning, and mechanical pressing.

[0003] In the production of pelleted feed, screening is a crucial process, primarily responsible for removing dust from the pellets to ensure the quality of the finished product. Currently, most common screening devices employ a left-right swinging design, using the swinging motion to allow dust to pass through the screen and be discharged. However, such equipment easily generates dust during operation, leading to a dust-filled atmosphere in the workshop. This not only seriously affects the air quality of the production environment but also poses a potential threat to the health of operators. Summary of the Invention

[0007] The pellet feed screening device of this application embodiment can efficiently remove dust from pellet feed and effectively suppress the diffusion of dust during the screening process, while achieving centralized collection of discharged dust. This not only saves feed production costs but also significantly reduces the subsequent environmental cleanup burden.

[0008] In addition, the pellet feed screening device proposed in this application may also have the following additional technical features: In one embodiment of this application, the support assembly includes a support rod and a ball bearing, wherein the support rod is mounted on the screening cylinder, and the ball bearing is rotatably connected to one end of the support rod facing the screening cylinder, and the ball bearing is in contact with the outer wall of the screening cylinder.

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] The pellet feed screening device of this application embodiment will now be described with reference to the accompanying drawings.

[0020] like Figures 1-6 As shown, the pellet feed screening device of this application embodiment may include a base plate 1, and a closed drive mechanism 2, a screening mechanism 3, an exhaust mechanism 4 and a recycling mechanism 5 installed on the base plate 1.

[0021] It should be noted that the base plate 1 described in the above embodiments has a convex-shaped structure.

[0022] The screening mechanism 3 may include a screening cylinder 31, a support assembly 32, a screen cylinder 33, a stirring paddle 34, and a transmission assembly 35.

[0023] As one possible scenario, one end of the sieve cylinder 33 described in the above embodiment is chamfered, thereby reducing the diameter of one end of the sieve cylinder 33 and preventing the pellet feed from leaking out when it is loaded into the sieve cylinder 33.

[0024] It should be noted that the bottom end of the screening cylinder 31 described in the above embodiment is provided with a groove to collect feed with insufficient particle size.

[0025] The support assembly 32 is installed inside the screening cylinder 31, and the screen cylinder 33 is located inside the support assembly 32. The screen cylinder 33 is in contact with the support assembly 32. The stirring paddle 34 is rotatably installed inside the screen cylinder 33. The transmission assembly 35 is installed on the screening cylinder 31 and is connected to the screen cylinder 33 in a transmission manner.

[0026] It should be noted that the stirring paddles 34 described in the above embodiments are all configured with a mesh structure, and one end of the stirring paddle 34 is provided with a drive groove for the closed drive mechanism 2 to engage.

[0027] Specifically, driven by the transmission component 35, the screen cylinder 33 begins to rotate inside the screening cylinder 31 under the support of the support component 32, thereby achieving the screening of dust in the pellet feed. Subsequently, driven by the closed drive mechanism 2, the stirring paddle 34 rotates inside the screen cylinder 33, thereby further accelerating the screening of dust in the pellet feed.

[0028] The exhaust system 4 may include an exhaust component 41 and an exhaust component 42.

[0029] It should be noted that the exhaust end of the exhaust component 41 described in the above embodiment is arranged facing the groove on the screening cylinder 31.

[0030] The exhaust component 41 is installed on the base plate 1, the air outlet component 42 is installed on the inner wall of the screening cylinder 31, and the air outlet end of the exhaust component 41 is connected to the screening cylinder 31, and the air outlet component 42 is connected to the exhaust component 41.

[0031] Specifically, the exhaust component 41 draws in outside air and discharges the drawn air into the screening cylinder 31 through the exhaust component 42, thereby blowing out the dust in the pellet feed during screening, accelerating the screening of pellet feed dust while preventing dust from leaking out of the screening cylinder 31.

[0032] The air outlet assembly 42 may include a connecting pipe 421 and an exhaust pipe assembly 422.

[0033] It should be noted that the exhaust pipe assembly 422 described in the above embodiment is composed of multiple exhaust pipes, and multiple air ports are opened on the exhaust pipes, with the air ports facing the screen cylinder 33.

[0034] The connecting pipe 421 is connected to the air outlet of the exhaust assembly 41, and the exhaust pipe group 422 is installed inside the screening cylinder 31. The connecting pipe 421 passes through the screening cylinder 31 and is connected to the exhaust pipe group 422.

[0035] It is understood that the air drawn by the exhaust assembly 41 described in the above embodiments is partially discharged into the connecting pipe 421 and then into the exhaust pipe group 422 via the connecting pipe 421, thereby achieving the screening of dust in the pellet feed.

[0036] Specifically, the pellet feed screening device provided in this application can be used to screen dust in pellet feed. In actual operation, the relevant personnel move the closed drive mechanism 2 from the screening cylinder 31 and pour the pellet feed to be screened into the screening cylinder 33. After pouring, the closed drive mechanism 2 closes one end of the screening cylinder 31. Then, the transmission component 35 drives the screening cylinder 33 to rotate in the screening cylinder 31 to complete the screening of dust in the pellet feed. Subsequently, under the drive of the closed drive mechanism 2, the stirring paddle 34 rotates in the screening cylinder 33 to accelerate the screening of dust in the pellet feed. Under the action of the support component 32, the stability of the screening cylinder 33 rotating in the screening cylinder 31 is ensured to avoid shaking.

[0037] During screening, the exhaust assembly 41 draws in outside air and discharges it into the screening cylinder 31 to remove screening dust. Some of the air is discharged into the exhaust pipe assembly 422 through the connecting pipe 421. As the screening cylinder 33 rotates, the air discharged from the exhaust pipe assembly 422 accelerates the screening of dust and discharges the screened dust into the recycling mechanism 5 for filtration. The gas discharged from the exhaust end of the exhaust assembly 41 blows the dust in the groove of the screening cylinder 31 out of the screening cylinder 31. At the same time as screening dust, the feed particles with unfilled size are discharged from the screening cylinder 33 and remain in the groove inside the screening cylinder 31. Since the weight of the unfilled feed particles is greater than that of the dust, the dust mixed with the unfilled feed particles in the groove is discharged together and filtered by the recycling mechanism 5.

[0038] After screening, the closed drive mechanism 2 opens the screening cylinder 31 and pulls the screen cylinder 33 out from the support component 32 on the screening cylinder 31, thereby realizing the feeding of the screened pellet feed and cleaning up the feed with insufficient particle size remaining in the groove. Finally, the screening steps are repeated to realize the processing of subsequent feed.

[0039] The above-described implementation method can efficiently remove dust from pelleted feed and effectively suppress the spread of dust during the screening process, while also enabling centralized collection of discharged dust. This not only saves on feed production costs but also significantly reduces the subsequent environmental cleanup burden.

[0040] In one embodiment of this application, such as Figure 3 As shown, the support assembly 32 may include a support rod 321 and a ball bearing 322.

[0041] It should be noted that the support component 32 described in the above embodiments is provided in three sets.

[0042] Among them, the support rod 321 is installed on the screening cylinder 31, and the ball bearing 322 is rotatably connected to the end of the support rod 321 facing the screen cylinder 33, and the ball bearing 322 is in contact with the outer wall of the screen cylinder 33.

[0043] As one possibility, the support rod 321 can be replaced with a telescopic type to support support components 32 of different diameters.

[0044] Specifically, the support rod 321 is used to install the ball bearing 322, and then the support rod 321 is used to support the screen cylinder 33, and the ball bearing 322 is used to prevent the rotation of the screen cylinder 33 from being affected.

[0045] In one embodiment of this application, such as Figure 4 As shown, the transmission assembly 35 may include a transmission motor 351, a drive gear 352, and a driven gear 353.

[0046] It should be noted that the driven gear 353 described in the above embodiment has a cross groove in the middle, which engages with one end of the screen cylinder 33, facilitating the driving of the screen cylinder 33.

[0047] The drive motor 351 is mounted on the screen cylinder 33. The drive gear 352 is connected to the output end of the drive motor 351. The driven gear 353 is rotatably connected to the screen cylinder 33. One end of the screen cylinder 33 passes through the screening cylinder 31 and is engaged with the screen cylinder 33. The drive gear 352 meshes with the driven gear 353.

[0048] Specifically, driven by the drive motor 351, the drive gear 352 drives the driven gear 353 to rotate. Then, as the driven gear 353 rotates, the screen cylinder 33 rotates in the screening cylinder 31, thereby achieving the screening of the granular feed dust in the screen cylinder 33.

[0049] In one embodiment of this application, such as Figure 3 and Figure 5 As shown, the exhaust assembly 41 may include a high-pressure fan 411, an intake pipe 412, and an exhaust pipe 413.

[0050] It should be noted that one end of the exhaust assembly 41 described in the above embodiment is connected to the screening cylinder 31, and the exhaust pipe 413 is arranged facing the groove on the screening cylinder 31.

[0051] The high-pressure blower 411 is mounted on the base plate 1, the air inlet pipe 412 is connected to the air inlet end of the high-pressure blower 411, and the exhaust pipe 413 is connected to the air outlet end of the high-pressure blower 411.

[0052] Specifically, under the action of the high-pressure blower 411, outside air is drawn in through the air inlet pipe 412 and discharged into the screening cylinder 31 through the exhaust pipe 413, thereby realizing the discharge of dust after screening.

[0053] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the enclosed drive mechanism 2 may include a drive assembly 21, a fixing frame 22, an enclosed plate 23, a second drive motor 24, and a limiting plate 25.

[0054] It should be noted that a sealing ring is installed on the end of the sealing plate 23 facing the screening cylinder 31 as described in the above embodiment to increase the sealing between the sealing plate 23 and the screening cylinder 31 and reduce the leakage of dust.

[0055] It should be noted that the fixing frame 22 described in the above embodiment is provided in two sets.

[0056] The drive assembly 21 is mounted on the screen cylinder 33 via the fixing frame 22. The sealing plate 23 is connected to the drive assembly 21. The second drive motor 24 is mounted on the sealing plate 23. The output end of the second drive motor 24 passes through the sealing plate 23 and is connected to the stirring paddle 34. The limiting plate 25 is mounted on the bottom end of the sealing plate 23. A sliding groove for the limiting plate 25 to slide is provided on the bottom plate 1.

[0057] Specifically, driven by the drive component 21, the fixed frame 22 moves the closing plate 23 away from or close to the screening cylinder 31. Under the action of the limiting plate 25, the movement path of the closing plate 23 is limited, and the closing plate 23 is used to seal one end of the screening cylinder 31, reducing the leakage of dust.

[0058] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the drive assembly 21 may include a first drive motor 211, a drive sprocket 212, a driven sprocket 213, a meshing gear 214, and a stroke screw 215.

[0059] It should be noted that the meshing gear 214 and the stroke screw 215 described in the above embodiments are provided in two sets.

[0060] The first drive motor 211 is mounted on the screening cylinder 31. The drive sprocket 212 is connected to the output end of the first drive motor 211. The driven sprocket 213 is mounted on the screening cylinder 31. The drive sprocket 212 is connected to the driven sprocket 213 via a chain. The meshing gear 214 is rotatably mounted on the screening cylinder 31. The stroke screw 215 is threaded through the meshing gear 214 and connected to the closing plate 23. The meshing gear 214 and the driven sprocket 213 mesh with the meshing gear 214 respectively.

[0061] Specifically, under the action of the first drive motor 211, the drive sprocket 212 is rotated, and under the action of the chain, the driven sprocket 213 is rotated. Under the rotation of the drive sprocket 212 and the driven sprocket 213, the meshing gear 214 drives the stroke screw 215 to move, thereby controlling the closing plate 23 to move away from or close to the screening cylinder 31, so as to achieve the sealing treatment of one end of the screening cylinder 31.

[0062] In one embodiment of this application, such as Figure 1 and Figure 6 As shown, the recycling mechanism 5 may include a recycling pipe 51, a transfer pipe 52, and a filter assembly 53.

[0063] It should be noted that a circular screen is installed at one end of the recovery pipe 51 near the screening cylinder 31 as described in the above embodiment to prevent feed with insufficient particle size from being blown away by the wind and discharged from the recovery pipe 51.

[0064] The recovery pipe 51 is connected to the screening cylinder 31, and the filter assembly 53 is connected to the recovery pipe 51 through the transfer pipe 52.

[0065] Understandably, the dust from the screening is discharged through the recovery pipe 51, and the discharged dust enters the filter assembly 53 through the transfer pipe 52 for further filtration, thereby reducing dust leakage.

[0066] The filter assembly 53 may include a recovery bin 531, an exhaust pipe 532, and a filter plate 533.

[0067] It should be noted that the position of the filter plate 533 described in the above embodiment is higher than the position of the transfer pipe 52 connected to the recycling box 531.

[0068] The recycling bin 531 is installed on the base plate 1, the air outlet pipe 532 is connected to the recycling bin 531, and the filter plate 533 is installed inside the recycling bin 531.

[0070] In summary, the pellet feed screening device of this application can efficiently remove dust from pellet feed and effectively suppress the spread of dust during the screening process, while also achieving centralized collection of discharged dust.
