A drying device for feed puffing

Abstract

This invention discloses a drying device for feed extrusion, applied in the field of feed extrusion technology. The device includes a drying mechanism comprising a shell assembly and a drying component. When using the drying device, the operator feeds the feed to be dried into the shell through the feed inlet. The feed is sieved by the reciprocating movement of the filter conveyor belt. Simultaneously, the feed, which initially accumulates in a clump on the surface of the filter conveyor belt through the feed inlet, is evenly spread out on the belt surface by the reciprocating movement. This design achieves both sieving through the movement of the filter conveyor belt and uniform drying through the even spreading of the feed, facilitating the drying of extruded feed, reducing the inconvenience of subsequent transfer to a dedicated screening mechanism, and improving feed processing efficiency.

Description

Technical Field

[0001] This invention belongs to the field of feed extrusion technology, and specifically relates to a drying device for feed extrusion. Background Technology

[0002] Extruded feed, processed using extrusion technology, is pelleted feed. When the feed is squeezed out of the die under high pressure, the sudden release of moisture into the atmosphere causes a rapid drop in temperature and pressure, leading to rapid evaporation and volume expansion. Besides the general advantages of pelleted feed, it offers better palatability, higher digestibility, more varied shapes, the ability to be made into floating or sinking feed, and effective sterilization and toxin removal. The extruded feed then enters the drying process. Since some powder remains in the extruded pellets, screening is necessary to ensure subsequent feed quality. Currently, the screening process typically involves feeding the dried feed back into the screening mechanism, which is inconvenient for handling and transferring feed, increases the number of production steps, extends the production cycle, and leads to low efficiency. Furthermore, it makes collecting and cleaning the screened feed powder difficult, increasing the tediousness and inconvenience of subsequent manual cleaning. Summary of the Invention

[0003] The purpose of this invention is to provide a drying device for feed extrusion, which has the advantages of enabling feed screening and achieving uniform drying through the even spreading of feed, thus facilitating the drying of extruded feed. It also reduces the inconvenience of subsequent transfer to a dedicated screening mechanism, reduces intermediate handling costs, and improves feed processing efficiency. Furthermore, it effectively improves operational convenience in the feed drying process, reduces manual labor, and allows for the direct installation of a receiving bag or frame at one end of the guide plate, minimizing the inconvenience of regular manual cleaning.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a drying device for feed extrusion, comprising a drying mechanism, the drying mechanism comprising an outer shell assembly and a drying component, the outer shell assembly comprising a shell, the shell having an internal screening mechanism, the screening mechanism comprising a conveying component, a reciprocating component, and a linkage component, the conveying component comprising a first rotating rod and a second rotating rod, the reciprocating component comprising a first rod body, the linkage component comprising a fixed frame, the shell having an internal cleaning mechanism, the cleaning mechanism comprising a cleaning component, a moving component, and a transmission component, the cleaning component comprising a support frame, the moving component comprising a bracket, and the transmission component comprising a second rotating motor.

[0005] Using the above technical solution, when using the feed extrusion drying equipment, the operator feeds the feed to be dried into the shell through the feed inlet. The drying component then operates, coordinating with the conveying component to achieve feed conveying and drying. The conveying component drives the linkage and reciprocating components, which in turn move the filter conveyor belt back and forth, allowing the feed to be screened. Simultaneously, the feed, initially lumped onto the filter conveyor belt surface from the feed inlet, is evenly spread out under the reciprocating movement of the belt. This setup achieves both screening through the movement of the filter conveyor belt and uniform drying through the even spreading of the feed, facilitating the drying of extruded feed, reducing the inconvenience of transferring to a dedicated screening mechanism, minimizing intermediate handling costs, and improving feed processing efficiency. During the use of the feed extrusion drying equipment, dust is collected in the support frame. When dust needs to be treated, the transmission component drives the cleaning component, which in turn moves the support and brush plate inside the tray. The moving component allows for both lateral and small-range reciprocating movement of the brush plate. This brush plate movement increases the cleaning efficiency of the dust inside the tray, effectively removing dust adhering to the inside. Simultaneously, the dust inside the tray is swept to the sides and then guided to the outside of the housing by the guide plate. The tray has a slight inclination angle on its inner side, facilitating dust transfer to the guide plate. This design significantly improves operational convenience in the feed drying process, reduces manual labor, and allows for the direct placement of a receiving bag or frame at one end of the guide plate, minimizing the inconvenience of regular manual cleaning.

[0006] The present invention is further configured such that: one side of the top of the housing is connected to a feed inlet that extends through to the inside of the housing; the other side of the housing is fixedly installed with a discharge guide frame that extends through to the inside of the housing; a maintenance plate is bolted to the rear side of the housing; and guide plates extending through to the rear side of the housing are provided on both sides inside the housing.

[0007] Using the above technical solution, the feed inlet is used to put the feed to be dried into the shell, while the discharge guide frame facilitates the discharge of the dried feed. The inspection plate facilitates disassembly and maintenance of the shell, ensuring the operation of the mechanism, and the guide plate facilitates the discharge of dust from the feed.

[0008] The present invention is further configured such that: the drying component includes a mounting frame, the mounting frame is fixedly connected to the top of the inner side of the housing, a heating wire is provided on the inner side of the mounting frame, mounting rods fixedly connected to the mounting frame are fixedly installed at both ends of the heating wire, a pipe is provided at the top of the heating wire, a connecting pipe is connected between adjacent pipes, an air outlet is connected at the bottom of the pipe, a T-shaped pipe is connected at the top of the pipe located in the center of the mounting frame, a fan is fixedly installed at the top of the housing, and the air inlet of the fan is connected to one end of the T-shaped pipe.

[0009] Using the above technical solution, the operation of the heating wire will generate heat. At this time, in conjunction with the operation of the fan, the outside air is drawn into the three-way pipe, and then evenly distributed to multiple air outlets through the setting of pipes and connecting pipes. The air blown out of the air outlets will carry the heat and blow it towards the filter conveyor belt, thereby realizing the drying process.

[0010] The invention is further configured such that: both ends of the first and second rotating rods are rotatably connected to the housing via bearings; rollers are fitted onto the surfaces of both the first and second rotating rods; a filter conveyor belt is connected between the two rollers; retaining rings, made of flexible material, are fixedly fitted onto both sides of the filter conveyor belt; side plates are fitted onto both ends of the two rollers via bearings; snap-fit ​​strips are fixedly installed on the surfaces of the first and second rotating rods; snap-fit ​​grooves for engaging with the snap-fit ​​strips are provided inside the rollers; a rotating motor is fixedly installed on the surface of the housing; and the output end of the rotating motor is fixedly fitted onto the first rotating rod via a coupling.

[0011] Using the above technical solution, the operation of the rotating motor one will drive the rotating rod one and the rollers on its surface to rotate. The filter conveyor belt ensures synchronous rotation of the two rollers, thereby rotating the rotating rod two. The feed on the surface of the filter conveyor belt will be conveyed and transferred, while the retaining ring will limit the feed on the filter conveyor belt surface, preventing it from slipping off. The movement of the side plate will drive the two rollers to move on the surfaces of rotating rod one and rotating rod two respectively. The locking strip and locking groove ensure that the movement of the two rollers on the surfaces of rotating rod one and rotating rod two is guided, and synchronous rotation of rotating rod one, rotating rod two, and the rollers can still be achieved during this movement, ensuring the usability of the rollers.

[0012] The invention is further configured such that: the first rod body and the fixed frame are rotatably connected to each other; a connecting plate is fixedly sleeved on the surface of the first rod body; a guide block is fixedly sleeved on one end of the connecting plate; a guide ring is slidably sleeved on the surface of the guide block; a connecting member is fixedly installed on one side of the guide ring; an mounting member is fixedly installed on one end of the connecting member; a fixing member is fixedly installed on the bottom of the side plate located inside the housing; a bolt penetrating the mounting member to the inside of the fixing member is provided on one side of the mounting member; and both the mounting member and the fixing member are threadedly connected to the bolt.

[0013] Using the above technical solution, the rotation of rod one will drive the connecting plate to move, and the connecting plate will drive the guide block to move around rod one as the center. In the sliding connection between the guide block and the guide ring, the guide block can drive the guide ring to move back and forth, and the guide ring will synchronously drive the connecting parts and the mounting parts to move. The mounting parts will drive the fixing parts and the side plate to move through bolts.

[0014] The present invention is further configured such that: the fixed frame and the housing are fixedly connected to each other; the inner side of the fixed frame is rotatably connected to rod body two and rod body three via bearings; one end of rod body two and rod body one are fixedly sleeved with synchronous pulley one; synchronous pulley one is mutually connected to the two synchronous pulleys one; one end of rod body two is fixedly sleeved with rotating gear one; the surface of rotating gear one meshes with rotating gear two sleeved on the surface of rod body three; one end of rod body three is fixedly sleeved with bevel gear one; the surface of bevel gear one meshes with bevel gear two fixedly sleeved on rod body one.

[0015] Using the above technical solution, during the rotation of the rotating rod one, the synchronous rotation of the rotating rod one and the rod body two will be achieved through the setting of the synchronous pulley one and the synchronous belt one. The rod body two will drive the rotating gear one to rotate, and the rotating gear one will drive the rotating gear two to rotate. The rotating gear two will synchronously drive the rod body three to rotate, and the rod body three will drive the bevel gear one to rotate. The bevel gear one will drive the bevel gear two and the rod body one to rotate through meshing.

[0016] The invention is further configured such that: the support frame is located inside the filter conveyor belt and is fixedly connected to the housing; one side of the support frame is connected to the guide plate; a guide rod and a twisted shaft are respectively provided on both sides of the top of the support frame; a fixing plate is fixedly installed on one side of the side plate at one end of the roller body and fixedly connected to both ends of the guide rod; a fixing plate is fixedly installed on one side of the side plate at the other end of the roller body and rotatably connected to both ends of the twisted shaft; a guide plate is fixedly installed on the top of both the fixing plate and the fixing plate and fixedly connected to one side of the side plate; a guide member is slidably sleeved on the surface of the guide rod; a crossbar is fixedly installed on one side of the guide member; a brush plate is provided at the bottom of the crossbar and contacts the support frame; a slide rail is fixedly installed on the top of the brush plate; sliders are slidably connected to both ends of the slide rail surface; and a connecting block is fixedly installed at the bottom of the slider and fixedly connected to the crossbar.

[0017] Using the above technical solution, the support frame will support and collect feed dust smaller than the aperture of the filter conveyor belt, where the aperture of the filter conveyor belt is larger than the size of the feed particles. During the movement of the crossbar, the sliding connection between the guide rod and the guide component will guide the movement of the crossbar. Simultaneously, the crossbar will drive the connecting block, slider, and brush plate to move, with the brush plate cleaning the support frame. The slider and slide rail configuration allows the crossbar to adapt to the positional sliding between the crossbar and the brush plate while the side plate moves.

[0018] The invention is further configured as follows: a collar is sleeved on the surface of the first twisted shaft, a rotating ring fixedly connected to the bracket is rotatably sleeved on the surface of the first collar, a second twisted shaft is rotatably connected to the inner side of the bracket via a bearing, a second collar is sleeved on the surface of the second twisted shaft, a rotating ring is rotatably sleeved on the surface of the second collar, a guide rod fixedly connected to the bracket is slidably connected inside the rotating ring, and snap-fit ​​components for engaging with the first and second twisted shafts respectively are fixedly installed inside the first and second collars, one end of the second twisted shaft extends through to one side of the bracket and a bevel gear is fixedly installed thereon, a bevel gear four meshes with the surface of the third bevel gear, a connecting rod rotatably connected to the bracket is fixedly sleeved inside the fourth bevel gear, a linkage gear is fixedly sleeved on the surface of the connecting rod, and a rack fixedly connected to the fixed plate is meshed with the surface of the linkage gear.

[0019] Using the above technical solution, the rotation of the twisted shaft one is achieved through the snap-fit ​​mechanism in the collar one, allowing the collar one to move on the surface of the twisted shaft one. The movement of the collar one drives the bracket to move synchronously via the rotating ring one, which in turn drives the twisted shaft two and the linkage gear to move. During the movement of the linkage gear, the meshing of the gear rack is achieved, enabling the linkage gear to rotate. At this time, the linkage gear drives the connecting rod one and the bevel gear four to rotate synchronously, and the bevel gear four drives the bevel gear three and the twisted shaft two to rotate. The rotation of the twisted shaft two is achieved through the snap-fit ​​mechanism in the collar two, allowing the collar two to move on the surface of the twisted shaft two. The movement of the collar two then drives the crossbar to move synchronously via the rotating ring two.

[0020] The present invention is further configured such that: a mounting shell is fixedly installed on the surface of the rotating motor 2; a connecting rod 2 is fixedly sleeved at the output end of the rotating motor 2 through a coupling; a synchronous pulley 2 is fixedly sleeved at one end of the connecting rod 2 and one end of the twisted shaft 1; and a synchronous belt 2 passing through the mounting shell is mutually connected between the two synchronous pulleys 2 for mutual transmission.

[0021] Using the above technical solution, the operation of the second rotating motor will drive the second connecting rod to rotate. The synchronous rotation of the second connecting rod and the first twisted shaft is achieved through the arrangement of the second synchronous pulley and the second synchronous belt. The mounting housing provides support and protection for the second rotating motor.

[0022] In summary, the present invention has the following beneficial effects:

[0023] When using feed extrusion drying equipment, the operator feeds the feed to be dried into the shell through the feed inlet. The feed is then screened by the reciprocating movement of the filter conveyor belt. Simultaneously, the feed, initially lumped together on the surface of the filter conveyor belt, is evenly spread out by the belt's reciprocating movement. This setup achieves both screening through the filter conveyor belt and uniform drying through the even spreading of the feed, facilitating the drying of extruded feed, reducing the inconvenience of transferring it to a dedicated screening mechanism, minimizing intermediate handling costs, and improving feed processing efficiency.

[0024] In the use of feed extrusion drying equipment, dust is collected in the tray frame. The design of twisted shafts one and two allows for both lateral and small-range reciprocating movement of the brush plate. This brush plate movement increases the cleaning efficiency of the brush plate on the inside of the tray frame, effectively removing dust adhering to it. Simultaneously, the brush plate cleans the dust from the inside of the tray frame to the sides, and then guides it to the outside of the housing via the guide plate. The inner side of the tray frame has a slight inclination angle, further facilitating dust transfer to the guide plate. This design effectively improves operational convenience in the feed drying process, reduces manual labor, and allows for the direct installation of a receiving bag or frame at one end of the guide plate, minimizing the inconvenience of periodic manual cleaning.

The drying mechanism 1 includes a shell assembly 101 and a drying assembly 102. The shell assembly 101 includes a shell 1011. A screening mechanism 2 is provided inside the shell 1011. The screening mechanism 2 includes a conveying assembly 201, a reciprocating assembly 202 and a linkage assembly 203. The conveying assembly 201 includes a first rotating rod 2011 and a second rotating rod 2012. The reciprocating assembly 202 includes a first rod body 2021. The linkage assembly 203 includes a fixed frame 2039. When using the feed puffing drying device, the operator puts the feed to be dried into the shell 1011 through the feed inlet 1012. The feed is screened by the reciprocating movement of the filter conveyor belt 2014. Simultaneously, the feed, which is lumped together on the surface of the filter conveyor belt 2014 due to the feeding inlet 1012, will be evenly spread out on the surface of the filter conveyor belt 2014 as it moves back and forth. This design allows for screening in conjunction with the movement of the filter conveyor belt 2014, and also achieves uniform drying by spreading the feed evenly. This facilitates the drying of extruded feed, reduces the inconvenience of transferring it to the dedicated screening mechanism 2, reduces intermediate handling costs, and improves the processing efficiency of the feed.

Guide plates 1015 extending into the rear of the housing 1011 are provided on both sides of its interior. The feed inlet 1012 is used to feed the material to be dried into the housing 1011, while the discharge guide frame 1013 facilitates the discharge of the dried feed. The maintenance plate 1014 facilitates disassembly and maintenance of the housing 1011, ensuring the mechanism's usability. The guide plates 1015 facilitate the discharge of dust from the feed.

During the rotation of rod 1 2011, the synchronous rotation of rod 1 2011 and rod 2 2031 is achieved through the arrangement of synchronous pulley 1 2032 and synchronous belt 1 2033. Rod 2 2031 drives rotating gear 1 2034 to rotate, which in turn drives rotating gear 2 2035 to rotate. Rotating gear 2 2035 synchronously drives rod 3 2036 to rotate, which in turn drives bevel gear 1 2037 to rotate. Bevel gear 1 2037 then meshes with bevel gear 2 2038 and rod 1 2021 to rotate.

[0056] Brief description of operation: When using the feed extrusion drying equipment, the operator feeds the feed to be dried into the housing 1011 through the feed inlet 1012, and the feed will fall onto the surface of the filter conveyor belt 2014. At this time, the operation of the heating wire 1022 will generate heat. At the same time, the operation of the fan 1028 will draw outside air into the three-way pipe 1027, and then through the pipes 1024 and the connecting pipes 1025, the air will evenly reach multiple air outlets 1026. The air blown out of the air outlets 1026 will carry the heat and blow it onto the filter conveyor belt 2014, thereby realizing the drying process. The operation of the rotating motor 2019 drives the rotating rod 2011 and the rollers 2013 on its surface to rotate. The filter conveyor belt 2014 ensures synchronous rotation of the two rollers 2013, thereby rotating the rotating rod 2012. The feed on the filter conveyor belt 2014 is then conveyed and dried. The retaining ring 2015 limits the feed on the filter conveyor belt 2014 surface, preventing it from slipping off. During the movement of the side plate 2016, the two rollers 2013 will move on the surfaces of the first rotating rod 2011 and the second rotating rod 2012 respectively. The snap-fit ​​strip 2017 and snap-fit ​​groove 2018 can guide the movement of the two rollers 2013 on the surfaces of the first rotating rod 2011 and the second rotating rod 2012 respectively. During this movement, the first rotating rod 2011, the second rotating rod 2012 and the rollers 2013 can still rotate synchronously, which can ensure the use of the rollers 2013. In the rotation of the rotating rod 2011, the synchronous rotation of the rotating rod 2011 and the rod body 2031 is achieved through the setting of the synchronous pulley 2032 and the synchronous belt 2033. The rod body 2031 drives the rotating gear 2034 to rotate, and the rotating gear 2034 drives the rotating gear 2035 to rotate. The rotating gear 2035 synchronously drives the rod body 2036 to rotate, and the rod body 2036 drives the bevel gear 2037 to rotate. The bevel gear 2037 drives the bevel gear 2038 to rotate with the rod body 2021 through meshing. The rotation of the rod body 2021 will drive the connecting plate 2022 to move, and the connecting plate 2022 will drive the guide block 2023 to move around the rod body 2021 as the center. In the sliding connection between the guide block 2023 and the guide ring 2024, the guide block 2023 can drive the guide ring 2024 to reciprocate. The guide ring 2024 will synchronously drive the connecting piece 2025 and the mounting piece 2026 to move. The mounting piece 2026 will drive the fixing piece 2028 and the side plate 2016 to move via bolts 2027. This arrangement will realize the reciprocating movement of the filter conveyor belt 2014, thereby enabling the feed to be screened under the movement of the filter conveyor belt 2014.Simultaneously, the feed, which is lumped together on the surface of the filter conveyor belt 2014 due to the feeding inlet 1012, will be evenly spread out on the surface of the filter conveyor belt 2014 as it moves back and forth. This design allows for screening in conjunction with the movement of the filter conveyor belt 2014, and also achieves uniform drying by spreading the feed evenly, facilitating the drying of extruded feed. It also reduces the inconvenience of transferring the feed to the dedicated screening mechanism 2, reduces intermediate handling costs, and improves feed processing efficiency. The discharge guide frame 1013 facilitates the discharge of the dried feed. The inspection plate 1014 facilitates disassembly and maintenance of the internal parts of the housing 1011, ensuring the usability of the mechanism, while the guide plate 1015 facilitates the discharge of dust from the feed.

During the use of the feed extrusion drying device, dust is collected in the support frame 3011. The arrangement of the first twisted shaft 3013 and the second twisted shaft 3024 allows for both lateral and small-range reciprocating movement of the brush plate 3018. The moving trend of the brush plate 3018 increases the cleaning efficiency of the brush plate 3018 on the dust inside the support frame 3011, effectively cleaning the dust attached to the inside of the support frame 3011. Simultaneously, under the cleaning action of the brush plate 3018, the dust inside the support frame 3011 is cleaned to both sides of the support frame 3011, and then discharged to the outside of the housing 1011 via the guide plate 1015. The inner side of the support frame 3011 has a certain inclined angle design, which facilitates the transfer of dust to the guide plate 1015. This design effectively improves the operational convenience in the feed drying process, reduces manual operation, and allows for the direct installation of a receiving bag or frame at one end of the guide plate 1015, reducing the inconvenience of regular manual cleaning.

The support frame 3011 will support and collect feed dust smaller than the aperture of the filter conveyor belt 2014, wherein the aperture of the filter conveyor belt 2014 is larger than the size of the feed particles. During the movement of the crossbar 3017, the sliding connection between the guide rod 3012 and the guide member 30112 guides the movement of the crossbar 3017. Simultaneously, the crossbar 3017 drives the connecting block 30110, the slider 30111, and the brush plate 3018 to move. The brush plate 3018 cleans the support frame 3011.

The mounting housing 3035 provides support and protection for the rotating motor 3031.

[0062] Brief description of operation: In the use of the feed extrusion drying equipment, dust is collected in the support frame 3011. The support frame 3011 supports and collects feed dust smaller than the aperture of the filter conveyor belt 2014, where the aperture of the filter conveyor belt 2014 is larger than the size of the feed particles. When dust treatment is required, the operation of the second motor 3031 drives the second connecting rod 3032 to rotate. The synchronous rotation of the second connecting rod 3032 and the first twisted shaft 3013 is achieved through the arrangement of the second synchronous pulley 3033 and the second synchronous belt 3034. The mounting shell 3035 provides support and protection for the second motor 3031. The rotation of the twisted shaft 3013 is achieved through the snap-fit ​​3028 in the collar 3022, which moves the collar 3022 on its surface. This movement of the collar 3022, in turn, drives the bracket 3021 to move synchronously via the rotating ring 3023. The bracket 3021 then drives the twisted shaft 3024 and the linkage gear 30212 to move. During the movement of the linkage gear 30212, the meshing with the rack 30213 enables its rotation. At this point, the linkage gear 30212 drives the connecting rod 30211 and the bevel gear 30210 to rotate synchronously. The bevel gear 30210 then drives the bevel gear 3029 and the twisted shaft 3024 to rotate. The rotation of the second twisted shaft 3024 is achieved through the snap-fit ​​3028 in the second collar 3025, allowing the collar 3025 to move on the surface of the second twisted shaft 3024. This movement of the collar 3025, in turn, drives the crossbar 3017 to move synchronously via the second rotating ring 3026. This allows the bracket 3021 and the brush plate 3018 to move within the support frame 3011. During the movement of the crossbar 3017, the sliding connection between the guide rod 3012 and the guide member 30112 guides the movement of the crossbar 3017. Simultaneously, the crossbar 3017 drives the connecting block 30110, the slider 30111, and the brush plate 3018 to move, with the brush plate 3018 cleaning the support frame 3011. By configuring the slider 30111 and the slide rail 3019, the crossbar 3017 can adapt to the sliding position between the crossbar 3017 and the brush plate 3018 while the side plate 2016 moves. This configuration also allows for small-range reciprocating movement of the brush plate 3018 while it moves laterally. This movement of the brush plate 3018 increases its efficiency in cleaning dust from the inside of the support frame 3011, effectively removing dust adhering to the inside of the support frame 3011. Simultaneously, under the cleaning action of the brush plate 3018, the dust inside the support frame 3011 is moved to both sides of the support frame 3011 and then guided to the outside of the housing 1011 via the guide plate 1015. The inner side of the support frame 3011 has a certain tilt angle design, which further facilitates the transfer of dust to the guide plate 1015.This setup effectively improves operational convenience in the feed drying process and reduces manual labor. A receiving bag or frame can be directly installed at one end of the guide plate 1015, reducing the inconvenience of regular manual cleaning.
