Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and particularly relates to a material leveling device used in puffed material drying equipment. Background Art

[0002] During pre-treatment or pre-pressing of oilseeds, puffing may be necessary. Oilseed puffing is the process of converting oilseeds into porous, expanded materials using extrusion equipment. Prior to puffing, the oilseeds are typically crushed and rolled. Examples include soybean green pellet puffing and leaching processes and rice bran puffing and leaching processes, which are widely used in oil extraction. Before puffing the green oilseeds, the moisture and temperature of the oilseeds must be regulated. During puffing, the oilseeds undergo a high-pressure, wet-heat treatment. The resulting puffed material has a relatively high temperature and moisture content, making it soft and brittle. Therefore, the puffed material should be dried and cooled, and its temperature and moisture adjusted to meet the requirements of subsequent processes.

[0003] At present, in the oil pretreatment and pre-pressing process, a flat plate dryer is generally used to dry the oil. The flat plate dryer is a rectangular structure with multiple layers of flat plates with steam sleeves arranged in an overlapping manner. The material enters from the top and falls on the flat plate to be heated by indirect steam. At the same time, there is a scraper chain mechanism on the flat plate to push the material forward, and it falls at the tail end of the flat plate and falls into the next layer of flat plate. In this way, it passes through each layer of flat plate in turn. Under the heating of indirect steam, the moisture in the material evaporates and is discharged through the air outlet at the top of the flat plate dryer, and the material is finally discharged from the bottom outlet.

[0004] However, in the actual production process, the scraper chain used in the flat dryer needs to push the material repeatedly, and the material is prone to uneven distribution and accumulation, which affects the drying effect. In addition, the material is easily crushed during the pushing process, resulting in an increase in the powder content of the material and reduced material quality. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved material refining device for puffed material drying equipment.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A material leveling device for puffed material drying equipment comprises a base plate, a dispersing component correspondingly arranged on the base plate, and a driving component, wherein the base plate is formed with a plurality of drying areas spaced apart along the left-right direction, and a discharge area arranged between each two adjacent drying areas and used for discharging the material downward; the dispersing component is formed with a plurality of compartments flattened on the surface of the base plate, the driving component drives the dispersing component and drives the plurality of compartments to move along the left-right direction, and the material is dispersed from top to bottom into each compartment and passes through each drying area and the discharge area in sequence as the dispersing component moves.

[0008] According to a specific embodiment and preferred aspect of the present invention, there are multiple bottom plates that are spaced apart from each other, and the material falls layer by layer onto each bottom plate from top to bottom through the unloading area. Here, a multi-layer bottom plate layout is adopted to increase the layered movement path of the material and further improve the drying effect.

[0009] Preferably, the movement directions of the materials on two adjacent bottom plates are opposite.

[0010] Preferably, the dispersing component comprises a plurality of partitions spaced apart in the left-right direction, with compartments formed between two adjacent partitions. The structure is simple and easy to install and implement.

[0011] According to another specific embodiment and preferred aspect of the present invention, each two adjacent bottom plates are divided into a material-splitting group, and a driving component drives multiple partitions to reciprocate between the upper and lower bottom plates in a material-splitting group. In this way, the material forms a reciprocating motion from top to bottom, which enhances the material's tumbling effect and improves the drying effect.

[0012] Preferably, the driving component adopts an annular transmission chain, and the plurality of partitions are fixedly arranged on the annular transmission chain and reciprocate in an annular manner.

[0013] Specifically, the ring-shaped transmission chain includes an upper chain body and a lower chain body connected at their ends. In a material-splitting group, the upper chain body is positioned near the upper surface of the upper base plate, and the lower chain body is positioned near the lower surface of the lower base plate. Here, the spacing between the upper and lower chains and the upper surface of the corresponding base plate is sufficient to allow the partition to push the material to move.

[0014] According to another specific embodiment and preferred aspect of the present invention, multiple unloading areas in upper and lower adjacent bottom plates are staggered and arranged vertically, with materials unloaded from the upper unloading area and falling into the corresponding drying area below. This ensures that the materials fall into the drying area layer by layer from top to bottom.

[0015] According to another specific embodiment and preferred aspect of the present invention, a plurality of discharge holes spaced apart along the front-to-back direction are provided in the discharge area, wherein each discharge hole is a rectangular hole and extends along the front-to-back direction.

[0016] In addition, a discharge channel extending downward from the edge of each discharge hole is formed on the bottom plate.

[0017] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:

[0018] The scraper chain used in the flat plate dryer of the prior art needs to push the material repeatedly, and the material is prone to uneven distribution, which affects the drying effect, and the material is easily crushed during the pushing process, resulting in an increase in the powder degree of the material and a reduction in the quality of the material. The present application comprehensively designs the structure of the material leveling device used in the puffed material drying equipment, cleverly solving the shortcomings and defects of the prior art. With the material leveling device, when the material is fed from top to bottom, the material is evenly dispersed and falls into each compartment under the movement of multiple compartments, and moves along the surface of the bottom plate. After being dried in the corresponding drying area, it enters the adjacent unloading area and is discharged downward. Therefore, compared with the prior art, the present invention is based on the arrangement of multiple drying areas and unloading areas on the bottom plate, and the falling material is dispersed in each compartment through a dispersing component, and is dried and unloaded in each drying area and unloading area respectively as the compartment moves, effectively reducing damage to the material and improving the material quality. On the other hand, the falling material is evenly dispersed, which is beneficial to improving the material drying effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figures 1 to 3 As shown, the material refining device for the expanded material drying equipment of this embodiment includes a base plate 1, a dispersing component 2 and a driving component 3 correspondingly arranged on the base plate 1.

[0032] Specifically, there are multiple bottom plates 1, and the multiple bottom plates 1 are spaced apart in the upper and lower directions, wherein each bottom plate 1 is divided into a drying area q1 for drying materials and a unloading area q2 for unloading materials downwards. There are multiple unloading areas q1 and drying areas q2 respectively, and the multiple drying areas q1 and the multiple unloading areas q2 are staggered in the left and right directions, that is, a unloading area q2 is set between every two adjacent drying areas q1, and the materials fall layer by layer on each bottom plate 1 through the unloading area q2 from top to bottom.

[0033] Multiple unloading areas q2 in adjacent bottom plates 1 are staggered in the upper and lower directions, that is, the material is discharged downward through any unloading area q2 and falls into the corresponding drying area q1 in the bottom plate 1 below; the bottom plate 1 is provided with multiple air holes k1 located in each drying area q1 for the passage of drying gas, and unloading holes k2 located in each unloading area q2, wherein the air holes k1 are all circular holes for the passage of drying gas, and the hole diameter is smaller than the diameter of the material particles; each unloading hole k2 is a rectangular hole and extends along the front-to-back direction, wherein each unloading area q2 has multiple unloading holes k2, and they are spaced apart along the front-to-back direction.

[0034] In order to further improve the drying effect, in each unloading area q2, the area between two adjacent unloading holes k2 is provided with an air hole k1; and a unloading channel t extending downward from the edge of each unloading hole k2 is also formed on the bottom plate 1.

[0035] In this example, the dispersing component 2 forms a plurality of compartments g flatly laid on the surface of the bottom plate 1. The driving component 3 drives the dispersing component 2 and drives the plurality of compartments g to move along the surface of the bottom plate 1. The material is dispersed from top to bottom and falls into each compartment g. As the dispersing component 2 moves, the material passes through each drying area q1 and unloading area q2 in sequence.

At the same time, each two adjacent bottom plates 1 are divided into a material mixing group, and the driving component 3 drives the plurality of partitions 20 to reciprocate between the upper and lower bottom plates 1 in a material mixing group.

[0037] For ease of implementation, the drive component 3 utilizes an annular transmission chain, with multiple baffles 20 fixedly mounted on the annular transmission chain and configured to reciprocate in an annular manner. In some embodiments, the annular transmission chain includes an upper chain body 30 and a lower chain body 31 connected at their ends. In a material leveling group, the upper chain body 30 is positioned near the upper surface of the upper base plate 1, while the lower chain body 31 is positioned near the upper surface of the lower base plate 1. The spacing between the upper and lower chains and the corresponding upper surfaces of the base plates is sufficient to allow the baffles to propel the material.

[0038] In summary, with the material leveling device, when the material is fed from top to bottom, the material is evenly dispersed and falls into each compartment under the movement of multiple compartments, and moves along the surface of the bottom plate. After being dried in the drying area, it enters the unloading area and is discharged downward; therefore, compared with the prior art, the present invention is based on the arrangement of multiple drying areas and unloading areas on the bottom plate, and disperses the falling materials into each compartment through the dispersion components, and realizes drying and unloading in each drying area and unloading area respectively with the movement of the compartments, which effectively reduces the damage to the material and improves the material quality; on the other hand, the falling materials are evenly dispersed, which is beneficial to improving the material drying effect; thirdly, a multi-layer bottom plate layout is adopted to increase the layered movement path of the material, further improving the drying effect, and at the same time, the material forms a reciprocating motion from top to bottom, which improves the turning effect of the material, which is beneficial to improving the drying effect; fourthly, the structure is simple and easy to install and implement.
