[0002] The quality preservator is an essential device in the feed pelleting system. During use, the quality preservator can heat and humidify the powdery feed to be pelletized, and keep it warm for a long time, so that the powdery material has enough time to contact with steam. In this way, the powdery material can be gelatinized, which is convenient for pressing into pellet feed, and can improve the water resistance of the pellet feed and improve the surface and internal quality of the pellet feed.

[0003] However, some powdery materials in the warehouse are prone to moisture absorption and agglomeration after being piled up for a period of time. When filling into the quality preservator, the agglomerated materials are difficult to be fully mixed with steam and gelatinized, resulting in insufficient gelatinization degree, which in turn affects the quality of the pellet feed.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0021] An embodiment of the present application discloses a feed quality preservator. Referring to Figure 1 , Figure 2 and Figure 3 , it includes a cylinder body 1. A first rotating shaft is rotatably arranged in the cylinder body 1, and the axis of the first rotating shaft is horizontal. A screw blade 2 for stirring the powder material is arranged on the outer wall of the first rotating shaft. A feed inlet is arranged at the top of the cylinder body 1. A discharge pipe 11 is welded to the bottom of the cylinder body 1, and a valve 111 is installed on the discharge pipe 11. A hopper 3 is bolted to the cylinder body 1 at the feed inlet. A filter screen 31 for filtering and leaving the lumpy material is welded to the bottom of the hopper 3. An abrasive device 4 for crushing the lumpy material is installed in the hopper 3. A first driving member 51 for driving the first rotating shaft to rotate is installed on the cylinder body 1. A steam generator (not shown in the figure) for injecting steam into the cylinder body 1 is also externally connected to the outside of the cylinder body 1.

[0022] In the embodiment of the present application, the staff can pour the powder material into the hopper 3. The powder material can enter the cylinder body 1 after passing through the filter screen 31, while the lumpy material in the powder material remains on the filter screen 31. The lumpy material can be crushed by the abrasive device 4 in the hopper 3 and can pass through the filter screen 31. A feed quality preservator of the present application can crush the lumpy material when it enters the cylinder body 1 and enable it to be fully mixed with steam in the cylinder body 1 and gelatinized, having the effect of improving the production quality of the granular material.

[0023] Further, the abrasive device 4 includes a second rotating shaft 41 and a plurality of abrasive rollers 42. The second rotating shaft 41 is coaxially and rotatably arranged in the hopper 3. The plurality of abrasive rollers 42 are circumferentially and spaced apart around the second rotating shaft 41 on the outer wall of the second rotating shaft 41, and the abrasive rollers 42 are located at one end of the second rotating shaft 41 close to the filter screen 31. A second driving member 52 for driving the second rotating shaft 41 to rotate is installed on the cylinder body 1.

[0024] In the embodiment of the present application, a cover plate is installed on the top of the hopper 3, and a feeding port is provided on the cover plate. The staff can pour the powder material into the hopper 3 from the feeding port, which can avoid the powder material from scattering out of the hopper 3. Both the first driving member 51 and the second driving member 52 can adopt driving motors to drive the corresponding rotating shafts to rotate. By starting the second driving member 52, the second rotating shaft 41 can be driven to rotate, so that the plurality of abrasive rollers 42 rotate around the axis of the second rotating shaft 41 and crush the blocky material on the filter screen 31.

[0025] In order to improve the crushing effect of the abrasive roller 42 on the blocky material, a pattern for rolling the blocky material is integrally fixed on the outer wall of the abrasive roller 42.

[0026] Specifically, the abrasive roller 42 is rotatably arranged on the outer wall of the second rotating shaft 41, and the axis of the abrasive roller 42 is perpendicular to the axis of the second rotating shaft 41. The pattern on the outer wall of the abrasive roller 42 is in rolling contact with the filter screen 31. In this way, it can be ensured that while the abrasive roller 42 rotates around the axis of the second rotating shaft 41, it can also rotate around its own axis, further improving the crushing effect on the blocky material.

[0027] Refer to Figure 4 , an inspection opening is provided on the outer wall of the cylinder body 1, an inspection door 6 is rotatably arranged at the inspection opening, and a limiting member 7 for restricting the rotation of the inspection door 6 is installed on the outer wall of the cylinder body 1. The limiting member 7 includes a stud 71, a threaded cylinder 72 and a mounting plate 73. The rotating shaft of the inspection door 6 is located above the inspection opening, the mounting plate 73 is welded to the movable end of the inspection door 6, and the stud 71 is rotatably arranged on the outer wall of the cylinder body 1 and is located below the inspection opening. A notch for allowing the stud 71 to be inserted and the movable end of the stud 71 to pass through the mounting plate 73 is provided on the mounting plate 73, and the threaded cylinder 72 is threadedly connected to the movable end of the stud 71 and is in movable abutment with the mounting plate 73.

[0028] In the embodiment of the present application, after the staff closes the inspection door 6, rotating the stud 71 can make it inserted into the notch of the mounting plate 73. Then, rotate the threaded cylinder 72 at the movable end of the stud 71 and make it abut against the mounting plate 73, and the rotation of the inspection door 6 can be restricted. When the staff needs to perform maintenance on the inside of the cylinder body 1, rotate the threaded cylinder 72 to loosen the mounting plate 73, and then turn the stud 71 out of the notch of the mounting plate 73, and the movable end of the inspection door 6 can be lifted to open the inspection opening.

[0029] Refer to Figure 5 , a gas spring support rod 8 for supporting the inspection door 6 when the inspection door 6 is opened is installed on the cylinder body 1. The gas spring support rod 8 includes a pressure cylinder 81 and a piston rod 82. One end of the pressure cylinder 81 is rotatably arranged on the outer wall of the cylinder body 1, and one end of the piston rod 82 is rotatably arranged on the inspection door 6.

[0030] In the embodiment of the present application, the pressure cylinder 81 of the gas spring support rod 8 is filled with inert gas, so that the pressure in the pressure cylinder 81 is higher than the atmospheric pressure. When the staff rotates the inspection door 6 and lifts the movable end of the inspection door 6, the piston rod 82 slides out of the pressure cylinder 81. Under the action of the air pressure in the pressure cylinder 81, the gas spring support rod 8 can support the inspection door 6.

[0031] Further, a connecting plate 9 is welded on the inspection door 6. A plurality of threaded holes 91 are arranged at intervals along the direction away from the rotating shaft of the inspection door 6 on the connecting plate 9. An adjusting bolt 10 for being threadedly connected to the threaded holes 91 is installed on the piston rod 82. By threadedly connecting the adjusting bolt 10 in different threaded holes 91, the maximum opening angle of the inspection door 6 can be adjusted.

[0032] The implementation principle of a feed quality preservator in the embodiment of the present application is as follows: The staff can pour the powder into the hopper 3. The powder can enter the cylinder body 1 after passing through the filter screen 31, while the lumpy materials in the powder remain on the filter screen 31. The lumpy materials can be crushed by the abrasive device 4 in the hopper 3 and can pass through the filter screen 31. After being crushed, the lumpy materials can be fully mixed with steam in the cylinder body 1 and gelatinized, which has the effect of improving the production quality of the granular materials.
