Description

Technical Field

[0001] The utility model relates to the technical field of puffed feed production and processing, in particular to a puffed feed processing and drying device. Background Art

[0002] Extruded feed is a pellet feed processed using extrusion technology. After extrusion, it needs to be dried using a drying device to remove excess moisture and improve feed quality and stability. The belt dryer is a commonly used continuous drying equipment for extruded feed. It is particularly suitable for drying flakes, strips, and granular materials with good air permeability. After extrusion, the feed pellets can be spread on a mesh belt and quickly dried by blowing hot air.

[0003] However, in the existing belt dryer, after the feed pellets are laid on the mesh belt, it is inconvenient to turn them over, resulting in some feed pellets always stacking together during the drying process. The overlapping parts of the feed pellets are difficult to fully contact with the hot air, thereby affecting the drying uniformity and drying efficiency of the feed pellets.

[0004] Therefore, we propose an expanded feed processing and drying device to solve the above problems. Utility Model Content

[0021] In the description of the present invention, it should be understood that terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are used solely to facilitate the description of the present invention and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 3-4, an expanded feed processing and drying device, including a pair of base frames 1, a roller 2 is rotatably installed between the two ends of the base frame 1, and a motor 3 is installed outside the base frame 1, the output shaft of the motor 3 is connected to the roller 2 to drive the roller 2 to rotate, a mesh belt 4 is sleeved between the rollers 2, and the mesh belt 4 is driven to transmit when the roller 2 rotates. A number of heating tubes 5 and fans 6 are also installed between the base frames 1, and the fans 6 are arranged under the heating tubes 5. The fans 6 and the heating tubes 5 cooperate to blow hot air upwards, thereby drying the feed particles on the mesh belt 4. The heating tubes 5 and the fans 6 are It is arranged on the inner side of the mesh belt 4, and the fan 6 is supported by the support frame 7, so that the hot air is closer to the upper mesh belt 4, thereby improving the drying efficiency. At the same time, the arrangement spacing between adjacent heating tubes 5 gradually expands from the middle section of the base frame 1 to both ends, so that the heating tubes 5 become more and more dense at the front end of the base frame 1, thereby preheating the feed particles and preventing the temperature from rising suddenly. The heating tubes 5 are most dense in the middle section of the base frame 1, realizing centralized drying and faster drying. The heating tubes 5 gradually become sparse at the rear end of the base frame 1, so that the temperature gradually drops and the feed particles are gradually cooled to room temperature.

[0025] See also Figure 1 A top box 8 is installed on the base frame 1, and a scraper 9 is installed on the inlet side of the top box 8. The scraper 9 is used to limit the laying thickness of the feed particles on the surface of the mesh belt 4 to prevent it from being too thick and difficult to dry. The scraper 9 is equipped with a screw 10 and a slide bar 11 parallel to each other. The bottom end of the screw 10 is rotatably connected to the scraper 9, and the top end of the screw 10 passes through the upper surface of the top box 8 and is screwed to the top box 8. The slide bar 11 slides through the upper surface of the top box 8, so that when the screw 10 is rotated, the screw 10 moves up and down, and the scraper 9 rises and falls under the limit of the slide bar 11. The height of the scraper 9 from the mesh belt 4 can be adjusted to facilitate adaptive adjustment of the spreading thickness of the feed particles.

[0026] See also Figure 2 A rake claw 12 is installed in the middle position of the top box 8, and a slide 13 is fixed on the rake claw 12. The interior of the slide 13 passes through and is screwed to a reciprocating screw 14. The reciprocating screw 14 is rotatably connected to the top box 8, and a motor 2 15 is installed at one end of the reciprocating screw 14 that passes through the top box 8. When the reciprocating screw 14 rotates, it drives the slide 13 to move back and forth, and the slide 13 drives the rake claw 12 to move back and forth along the width direction of the mesh belt 4, thereby turning over the feed particles and improving the uniformity of heating.

[0027] Furthermore, a slide groove 131 is provided on the slide 13, and a straight rail 16 is installed at the position of the slide 13 corresponding to the inner top of the top box 8. The slide 13 is slidably connected to the straight rail 16 through the slide groove 131, thereby limiting the slide 13 to prevent it from deflecting during movement, thereby maintaining the stability of the rake claw 12 in moving and turning over the feed particles.

[0028] Considering that the feed particles may pile up after being turned over by the rake claws 12, a scraper bar 2 19 is installed on the side of the reciprocating screw 14 inside the top box 8 through a support rod. The scraper bar 2 19 spreads the feed particles again for better drying.

[0029] See also Figure 1-2 In order to facilitate the discharge of the wet air generated by drying, an exhaust fan 17 and an exhaust pipe 18 are installed on the top box 8, and the exhaust pipe 18 is connected to the inside of the top box 8 through the exhaust fan 17.
