Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and particularly relates to a material turning device. Background Art

[0002] In the vegetable oil extraction plant, the wet meal coming out of the extractor generally contains about 30% solvent and a certain amount of water. The solvent in the wet meal needs to be evaporated, condensed and recovered for reuse, which is the most reasonable in terms of economy and environmental protection, and can ensure the safety of the meal storage and transportation process. In the conventional desolventizing process, the desolventizer used for wet meal desolventizing uses a higher temperature to desolventize the wet meal to obtain qualified meal, so that the residual solvent content in the meal reaches the corresponding quality index.

[0003] The common method to remove the solvent from wet meal is to use steam heating to vaporize the solvent and separate it from the meal. In this process, the meal particles are constantly turned over to increase the heat transfer rate. With the help of appropriate negative pressure gas phase state, the desolventizing effect is better. Therefore, most wet meal desolventizing equipment or processes use stirring, direct steam and indirect steam, and vacuum or negative pressure to achieve better desolventizing effects.

[0004] At present, the stirring device used in the desolventizing equipment generally includes a main shaft extending vertically into the barrel and a plurality of stirring paddles distributed on the main shaft at intervals above and below. When the material is fed from top to bottom, the main shaft rotates and drives the multiple stirring paddles to rotate to stir the material in the entire barrel. After the processing is completed, the material is discharged from the bottom of the barrel.

[0005] However, in the actual production process, the material stirring device used in the prior art has the following defects:

[0006] 1. A single main shaft is required to complete the stirring of the materials in the entire barrel cavity, which requires high power, high energy consumption and high cost;

[0007] 2. When using conventional stirring paddles, the material is prone to accumulation, and it is impossible to ensure that the material in each area of ​​the barrel is heated evenly, resulting in poor desolventizing effect. Utility Model Content

[0008] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved material turning device.

[0009] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0010] A material turning device is arranged below a material feed port, the turning device comprises a plurality of horizontal layers spaced apart from each other, and a pushing component for driving the material to turn along the upper surface of each horizontal layer, wherein each horizontal layer is formed with a material discharge channel which is located on the material movement path and passes through the upper surface of each horizontal layer from top to bottom, and the material turns over layer by layer along the upper surface of each horizontal layer, and falls onto the upper surface of the adjacent horizontal layer through the corresponding material discharge channel.

[0011] According to a specific implementation and preferred aspect of the utility model, multiple horizontal layers are aligned up and down; the horizontal movement directions of the materials on two adjacent horizontal layers are arranged in opposite directions. Here, the materials are turned over from top to bottom in a circuitous manner, which is conducive to further improving the uniformity of the distribution of the materials on each layer.

[0012] Preferably, every two adjacent horizontal layer plates constitute a layer plate group, and there are multiple layer plate groups; the material pushing component includes pushing pieces corresponding to the multiple layer plate groups one by one, wherein each pushing piece drives the materials on the corresponding two horizontal layer plates to move synchronously.

[0013] Specifically, the pusher includes an annular transmission chain and a power part for driving the annular transmission chain, wherein the annular transmission chain includes an upper chain body close to the upper surface of the horizontal layer plate located above and a lower chain body close to the upper surface of the horizontal layer plate located below, and the corresponding materials are driven to flip during the movement of the upper chain body and the lower chain body. Here, the movement of the annular transmission chain is used to achieve reverse and synchronous flipping of the upper and lower materials, which is conducive to maintaining the balance of material flipping and material discharge between two adjacent layers.

[0014] According to another specific implementation and preferred aspect of the utility model, there are multiple material discharge channels on each horizontal layer plate, and they are spaced apart along the horizontal movement direction of the material. Here, when discharging the material, it is beneficial for the material to be evenly dispersed and fall on the lower layer plate.

[0015] Preferably, the plurality of material discharge channels in each two adjacent horizontal layer plates are staggered in vertical arrangement; and / or, a rotary material discharge valve is provided in each material discharge channel, thereby facilitating material discharge control.

[0016] According to another specific implementation and preferred aspect of the utility model, the turning device further comprises a plurality of material-forming components correspondingly arranged above each horizontal layer and located on the material movement path, wherein a material-forming area is formed between the material-forming components and the upper surface of the corresponding horizontal layer, thereby ensuring the flatness of each material layer.

[0017] Preferably, each monolithic component comprises a plurality of monolithic modules spaced apart along the material movement direction, wherein a monolithic area is formed between the lower end of each monolithic module and the upper surface of the corresponding horizontal layer plate, and the height of the monolithic area is gradually reduced along the material movement direction.

[0018] According to another specific implementation and preferred aspect of the utility model, guide plates extending up and down are further provided on opposite sides of each horizontal layer plate, wherein the lower end of each guide plate is located directly above the lower horizontal layer plate; and / or the opposite side edges of each horizontal layer plate are bent downward. Here, considering that some materials are not discharged through the discharge channel, the materials can fall on the lower horizontal layer plate along the guide plates through the edges of the horizontal layer plate under the drive of the pushing component to avoid material accumulation.

[0019] In addition, the turning device also includes a receiving layer plate horizontally arranged above the top horizontal layer plate, wherein the material falls downward from the feed port onto the receiving layer plate, and the pushing component drives the material to move and spread on the surface of the receiving layer plate; the width of the receiving layer plate in the direction of material movement is smaller than the width of the top horizontal layer plate. Here, the material is initially distributed through the receiving layer plate so as to accurately control the amount of material falling to the top layer plate.

[0020] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:

[0021] The prior art uses a stirring device to stir the material, which needs to be completed by a single main shaft to stir the material in the entire barrel cavity, which requires high power, high energy consumption and high cost; and the conventional stirring paddle stirring cannot ensure that the material in each area of ​​the barrel is heated evenly, resulting in poor desolventizing effect; and the present application designs the structure of the material turning device as a whole, ingeniously solving the shortcomings and defects of the prior art. After adopting the material turning device, when the material is fed from top to bottom, the material falls on the top horizontal layer plate, and under the drive of the pushing component, the material moves along the surface of the horizontal layer plate The material on the upper surface of the lower horizontal layer plate is turned over by the pushing component, and falls on the upper surface of the lower horizontal layer plate through the discharge channel; the material on the upper surface of the next horizontal layer plate is then driven to turn over by the pushing component, and the above steps are repeated to implement the turning of the material from top to bottom layer by layer along the upper surface of each horizontal layer plate. Therefore, compared with the prior art, the utility model, on the one hand, turns over each layer of material separately through the pushing component, and the required working power is low, which effectively reduces energy consumption and reduces costs; on the other hand, the material is turned over and discharged layer by layer from top to bottom, which ensures the uniformity of material distribution in each area and effectively improves the desolventizing effect.

The material flips along the upper surface of each horizontal layer plate 1 layer by layer from top to bottom, and falls on the upper surface of the adjacent horizontal layer plate 1 through the corresponding material discharge channel t.

[0033] For the convenience of implementation, multiple horizontal shelves 1 are aligned vertically, and the horizontal movement directions of materials on two adjacent horizontal shelves 1 are opposite; there are multiple unloading channels t on each horizontal shelf 1, and they are distributed at intervals along the horizontal movement direction of materials; the multiple unloading channels t in every two adjacent horizontal shelves 1 are staggered vertically, and at the same time, in order to facilitate the control of unloading, a rotary unloading valve can also be provided in each unloading channel t; every two adjacent horizontal shelves 1 constitute a shelf group, and there are multiple shelf groups.

Considering that some materials are not discharged through the discharge channel, the materials can fall on the lower horizontal layer plate through the edge of the horizontal layer plate along the guide plate under the drive of the pushing component to avoid material accumulation.

[0035] In this example, the pushing component 2 includes pushing members 20 corresponding to the plurality of layer plate groups one by one, wherein each pushing member 20 drives the materials on the corresponding two horizontal layer plates 1 to move synchronously.

It should be particularly noted that the spacing between the upper and lower chain bodies and the corresponding horizontal layer plates is set according to the actual material size, and it is sufficient to push the material to turn over.

Here, the material is initially distributed through the receiving layer plate so as to accurately control the amount of material falling to the top layer plate.

[0040] In summary, after adopting the material turning device, when the material is fed from top to bottom, the material falls on the top horizontal layer plate, and under the drive of the pushing component, the material is turned along the upper surface of the horizontal layer plate, and falls on the upper surface of the lower horizontal layer plate through the unloading channel; the pushing component then drives the material on the upper surface of the next horizontal layer plate to turn, and repeats the above steps to implement the turning of the material along the upper surface of each horizontal layer plate from top to bottom layer by layer.
