Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to a conditioner with pins. Background Art

[0002] Feed processing usually requires operations such as puffing and pelleting. Before puffing and pelleting, the feed needs to be tempered. Tempering is to use a conditioner to stir the powdered mixture to be pelletized or puffed, and heat and humidify it so that the material absorbs the energy released by the steam and undergoes chemical changes.

[0003] To improve conditioning, most conditioners currently increase the number of paddles or agitators on the rotating shaft to increase the number of stirring strokes, resulting in more even dispersion and greater vapor absorption. However, because a 3-15mm gap must exist between the paddles and the drum wall, high-speed rotation creates a layer of material adhering to the drum wall as the material is conveyed forward. This layer of material is not stirred by the paddles, resulting in poor mixing and poor vapor absorption, which in turn reduces overall conditioning quality. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a conditioner with pins, which is used to solve the problem in the prior art that the layer of material between the cylinder wall and the blades is difficult to stir properly and has poor water vapor absorption effect.

[0005] To achieve the above-mentioned and other related purposes, the present invention provides a conditioner with a pin, comprising a barrel provided with a feed port and a discharge port, wherein a rotating shaft with a paddle is provided in the barrel, and the rotating shaft is connected to a driving component; a plurality of mounting holes are evenly spaced on the barrel wall, and a pin is detachably connected to the mounting hole, and at least a portion of the pin extends into the barrel wall.

[0006] In one embodiment of the present invention, the pin is located in the gap between the blades, and the pin and the blades are staggered.

[0007] In one embodiment of the present invention, the pin is located in the gap between adjacent blades and close to one of the blades.

[0008] In one embodiment of the present invention, the pins are evenly distributed along the circumference of the barrel and are equidistantly arranged along the axial direction of the barrel.

[0009] In one embodiment of the present invention, the pin and the mounting hole are detachably connected via a threaded connection or a quick-connect locking mechanism.

[0010] In one embodiment of the present invention, the driving component is disposed at one end of the barrel, a rotating bracket is disposed at the other end of the barrel, and the rotating shaft is rotatably disposed in the rotating bracket.

[0011] In one embodiment of the present invention, the portion of the pin extending into the barrel is in a conical column, cylindrical shape, cutter shape, capsule shape, special shape, etc. The shape of the pin is not limited to those mentioned above.

[0012] In one embodiment of the present invention, the portion of the pin extending into the barrel is cylindrical, and the top end of the pin has a tapered contraction portion with a gradually decreasing outer diameter.

[0013] In one embodiment of the present invention, the portion of the pin extending into the barrel is cylindrical, and the top end of the pin has a tapered expansion portion with a gradually increasing outer diameter.

[0014] In one embodiment of the present invention, the pin is in the shape of a tapered column with an outer diameter gradually increasing from top to bottom, and the end surface of the pin is a downwardly convex arc surface.

[0015] In one embodiment of the present invention, an air outlet is provided on the portion of the pin extending into the barrel, and an air inlet is provided on the portion of the pin located outside the barrel. The air inlet and the air outlet are connected via a connecting channel, and the air inlet is connected to an external pipeline and can be used for the injection of water vapor or other liquid additives.

[0016] In one embodiment of the present invention, the air outlet is located at the bottom of the pin, and the connecting channel vertically passes through the pin.

[0017] In one embodiment of the present invention, the air outlet holes are evenly distributed along the circumferential direction of the side wall of the pin, and the air outlet holes are spirally connected to the connecting channel.

[0018] In one embodiment of the present invention, the air outlet is located on a side wall of the pin.

[0019] In one embodiment of the present invention, the connecting channel has a contraction section with a gradually decreasing diameter.

[0020] As described above, the conditioner with pins of the present invention has the following beneficial effects:

[0021] 1. The utility model arranges multiple pins on the cylinder wall. On the one hand, it can increase the number of stirring and beating times of the material, so that the material with a large molecular chain is transformed into a small molecular chain structure, which is beneficial to water and heat absorption, improves the tempering effect, and reduces energy consumption; on the other hand, the pins form a resistance on the outermost ring, so that the layer of material in the gap between the cylinder wall and the blade changes direction when it is conveyed forward, so that this layer of material can also be stirred and broken up, and the exchange of the outer layer material and the inner layer material is realized, thereby improving the dispersion uniformity of the material.

[0023] 3. The utility model accelerates the water vapor passing through the connecting channel by shrinking the inner diameter thereof, and the high-speed water vapor is ejected from the air outlet, generating high shear force with the surrounding low-speed materials, thereby forming a vortex that diffuses to all sides, thereby improving the dispersion effect of the water vapor. Moreover, after the water vapor forms a vortex, it can further stir the materials in the cylinder wall and the gap between the blades, thereby improving the mixing effect of the materials in this layer and improving the water vapor absorption effect of the materials in this layer.

[0024] 4. The utility model gradually increases the outer diameter of the pin from top to bottom, and forms a sloped surface on the side wall of the pin, so that the material is rebounded to the outermost layer after hitting the side wall of the pin. At the same time, since the end face of the pin is a downwardly convex arc surface, the material can diffuse in different directions around after hitting the arc surface of the pin, thereby enhancing the beating and dispersing effect of the pin and making the dispersion and mixing of the material more uniform.

Those skilled in the art can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless there is a conflict.

[0039] Example 1

[0040] Please refer to Figures 1 and 2 This embodiment provides a conditioner with a pin, comprising a barrel 1, which is provided with a feed port and a discharge port. A rotating shaft 2 is provided in the barrel 1, which is connected to a driving component 4, and a plurality of paddles 3 are evenly spaced apart on the rotating shaft 2; a plurality of mounting holes 7 are evenly spaced apart on the barrel wall of the barrel 1, and a pin 8 is detachably connected to the mounting hole 7, and at least a portion of the pin 8 extends into the barrel wall.

[0041] The present invention arranges a plurality of pins 8 on the cylinder wall. On the one hand, the number of stirring and beating times of the material can be increased, so that the material with a large molecular chain is transformed into a small molecular chain structure, which is conducive to absorption and improves the conditioning effect. On the other hand, the pins 8 form a resistance on the outermost ring, so that the material in the gap between the cylinder wall and the blade 3 changes direction when being conveyed forward, so that the material in the gap between the cylinder wall and the blade 3 can also be stirred and broken up, thereby improving the dispersion uniformity of the material.

[0042] refer to Figure 2 The pin 8 is located in the interval between adjacent blades 3, so that the pin 8 and the blade 3 are staggered and the blade 3 will not be hindered by the pin 8 during the rotation process.

[0043] Furthermore, the pin 8 is located in the interval between adjacent blades 3 and close to the blade 3 on one side.

[0044] Furthermore, the pins 8 are evenly distributed along the circumference of the barrel 1 and are equidistantly arranged along the axial direction of the barrel 1 .

[0045] Furthermore, the pin 8 and the mounting hole 7 are detachably connected by a threaded connection or a quick-connect locking mechanism. All connection methods in the prior art that can achieve detachable connection between the pin 8 and the mounting hole 7 can be applied to the present utility model.

[0046] In this embodiment, the middle outer wall of the pin 8 is provided with an external thread, and the mounting hole 7 is provided with an internal thread, and the pin 8 and the mounting hole 7 are threadedly connected. When installing and removing the pin 8, it is only necessary to screw the pin 8, which is convenient to operate, and pins 8 of different shapes can be installed in the mounting hole 7 as needed.

[0047] Furthermore, a driving component 4 is provided at one end of the barrel 1, and a rotating bracket 5 is provided at the other end of the barrel 1, and the rotating shaft 2 is rotatably provided in the rotating bracket 5. By providing the rotating bracket 5, it is possible to ensure that the axis of the rotating shaft 2 does not deviate during the rotation process, ensure the smooth rotation of the rotating shaft 2, and prevent the blade 3 from scraping the barrel wall or colliding with the pin 8.

[0048] Furthermore, a plurality of steam ports 6 are provided on the wall of the barrel 1 .

[0049] Example 2

[0050] This embodiment provides a conditioner with pins, and the technical features provided by the conditioner include all the technical features disclosed in Example 1, except that:

[0051] In this embodiment, reference Figure 3 and Figure 4 The portion of the pin 8 extending into the barrel 1 is cylindrical, and the top end of the pin 8 has a tapered contraction portion with a gradually decreasing outer diameter.

[0052] By setting a conical contraction portion at the top of the pin 8, the material will move toward the blade 3 after hitting the conical contraction portion and be rolled toward the inner layer by the blade 3, thereby realizing the exchange of the outer layer material and the inner layer material and improving the mixing uniformity of the material.

[0053] Example 3

[0054] This embodiment provides a conditioner with pins, and the technical features provided by the conditioner include all the technical features disclosed in Example 2, except that:

[0055] refer to Figure 5 The part of the pin 8 extending into the barrel 1 is provided with an air outlet hole 81, and the part of the pin 8 outside the barrel 1 is provided with an air inlet hole. The air inlet hole and the air outlet hole 81 are connected through a connecting channel 82, and the air inlet hole is connected to the external pipeline.

[0056] Furthermore, the air outlet 81 is located at the bottom of the pin 8 , and the connecting channel 82 vertically passes through the pin 8 .

[0057] Water vapor or other additives are introduced into the barrel 1 through the connecting channel 82 in the pin 8. Since the pins 8 are evenly distributed on the barrel 1, the water vapor can be evenly distributed, which helps to fully mix the material and water vapor, improve the utilization rate of water vapor, and reduce the energy consumption of water vapor.

[0058] Example 4

[0059] This embodiment provides a conditioner with pins, and the technical features provided by the conditioner include all the technical features disclosed in Example 1, except that:

[0060] refer to Figure 6 The portion of the pin 8 that extends into the barrel 1 is cylindrical, and the top end has a tapered expansion portion with a gradually increasing outer diameter.

[0061] By setting a conical expansion portion at the top of the pin 8, the paddle 3 drives the material to be transported forward and hit the pin 8. Due to the angle of the conical expansion portion, part of the material is rebounded to the outermost layer after the impact, and the other part of the material is drawn into the paddle 3 and moves to the inner layer after the impact, thereby realizing the circulation of the outer layer material and the inner layer material and improving the mixing uniformity of the material.

[0062] Example 5

[0063] This embodiment provides a conditioner with pins, and the technical features provided by the conditioner include all the technical features disclosed in Example 4, except that:

[0064] refer to Figure 7 The part of the pin 8 extending into the barrel 1 is provided with a plurality of air outlet holes 81, and the part of the pin 8 outside the barrel 1 is provided with an air inlet hole. The air inlet hole and the air outlet hole 81 are connected through a connecting channel 82. The air inlet hole is connected to the external pipeline to introduce water vapor or other additives into the barrel 1; and the plurality of air outlet holes 81 are evenly distributed along the circumferential direction of the side wall of the pin 8, and the air outlet holes 81 are spirally connected to the connecting channel 82.

[0065] Furthermore, the upper portion of the connecting channel 82 has a contraction section with a gradually decreasing diameter.

[0066] Due to the shrinkage of the diameter of the connecting channel 82, the water vapor passing therethrough is accelerated, and the high-speed water vapor is ejected from the air outlet 81, generating high shear force with the surrounding low-speed materials, thereby forming a vortex that spreads to the surrounding areas; at the same time, the spiral connection between the air outlet 81 and the connecting channel 82 can promote the generation of vortexes, and the vortex formed by the water vapor can further stir the materials in the gap between the cylinder wall and the blades 3, thereby improving the water vapor absorption effect of this layer of materials and enhancing the mixing effect of this layer of materials, thereby improving the conditioning effect and reducing the water vapor energy consumption.

[0067] Example 6

[0068] This embodiment provides a conditioner with pins, and the technical features provided by the conditioner include all the technical features disclosed in Example 5, with the following differences:

[0069] refer to Figure 8 The air outlet 81 is arranged on the conical expansion portion of the pin 8 .

[0070] By arranging the air outlet 81 in the conical expansion portion, the water vapor can be ejected obliquely upward, directly acting on the cylinder wall, injecting water vapor into the material between the cylinder wall and the blade 3, and directly stirring the layer of material.

[0071] Example 7

[0072] This embodiment provides a conditioner with pins, and the technical features provided by the conditioner include all the technical features disclosed in Example 1, except that:

[0073] refer to Figure 9 The pin 8 is in the shape of a tapered column with an outer diameter gradually increasing from top to bottom. The end face of the pin 8 is a downwardly convex arc surface, and the air outlet 81 is located on the side wall of the pin 8.

[0074] Since the outer diameter of the pin 8 gradually increases from top to bottom to form a sloped surface, the material is rebounded to the outermost layer after hitting the side wall of the pin 8. At the same time, since the end face of the pin 8 is a downwardly convex arc surface, the material can diffuse in different directions around after hitting the arc surface of the pin 8, thereby enhancing the whipping and dispersing effect of the pin 8 and making the dispersion and mixing of the material more uniform.

[0075] In addition, the water vapor in the connecting channel 82 is reflected by the arc surface, so that the water vapor from the air outlet 81 can be sprayed obliquely upward and toward all sides, thereby promoting the contact and mixing of the water vapor with the outermost layer of material.

[0076] Example 8

[0077] This embodiment provides a conditioner with pins, and the technical features provided by the conditioner include all the technical features disclosed in Example 1, except that:

[0078] refer to Figure 10 The part of the pin 8 extending into the barrel 1 is in the shape of a cutter. The cutter-shaped pin 8 can cut the material it contacts, so that the material with a large molecular chain is transformed into a small molecular chain structure, which is conducive to absorption and improves the conditioning effect.

[0079] Example 9

[0080] This embodiment provides a conditioner with pins, and the technical features provided by the conditioner include all the technical features disclosed in Example 1, except that:

[0081] refer to Figure 11 The portion of the pin 8 that extends into the barrel 1 is in the shape of a capsule. The surface area of ​​the capsule-shaped pin 8 is larger, which can increase the collision area with the material and effectively improve the tempering effect.

[0082] In summary, the present invention, by providing multiple pins on the cylinder wall, can, on the one hand, increase the number of times the material is stirred and struck, transforming materials with large molecular chains into small molecular chains, which is beneficial for water and heat absorption, improves the conditioning effect, and reduces energy consumption. On the other hand, the pins form a resistance on the outermost ring, causing the layer of material between the cylinder wall and the paddle blades to change direction during forward conveyance, so that this layer of material can also be stirred and broken up, and the outer and inner layers of material can be exchanged, thereby improving the uniformity of material dispersion. Therefore, the present invention effectively overcomes the various shortcomings of the existing technology and has high industrial application value.
