Description

Technical Field

[0001] This utility model belongs to the field of feed processing technology, and specifically relates to a raw material screening device for feed processing. Background Technology

[0002] Feed is a general term for the food of animals raised by humans. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed ingredients such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. During the feed processing, the quality of feed ingredients is directly related to the quality of the final feed product. Feed ingredients often contain various small impurities, such as dust, sand, fragmented foreign matter, and microorganisms. The presence of these small impurities will seriously affect the nutritional value and safety of the feed.

[0003] Existing feed ingredient fine impurity treatment devices typically involve directly pouring the feed ingredients into the device and using a blower to blow air through them, removing fine impurities and dust from within the feed ingredients. However, during the pouring process, the feed ingredients often fall into the device in a clump-like manner, which prevents the blower from reaching the inside of the feed ingredients. Consequently, the fine impurities and dust inside the feed ingredients cannot be completely separated, affecting the quality of the raw feed product.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is a raw material screening device for feed processing, including a processing box. A fine filter screen is installed at an incline inside the processing box, dividing the interior of the processing box into a processing chamber and a dust collection chamber. A fan is installed on one side of the processing chamber, with the fan blowing in a direction perpendicular to the height of the processing chamber. A conveying pipe is installed at the upper end of the processing box, and a conveying component is installed inside the conveying pipe for quantitative material conveying. A hopper is installed at one end of the conveying pipe, and a dispersing component is installed at the other end of the conveying pipe for dispersing the material. The lower end of the dispersing component is connected to the interior of the processing chamber. A feeding component and a dust collection component are installed at the lower end of the processing box. The feeding component is connected to the interior of the processing chamber, and the dust collection component is connected to the interior of the dust collection chamber.

[0006] The conveying assembly includes a first power component, which is installed at one end of the conveying pipe. A transmission rod is coaxially mounted on the drive end of the first power component. The transmission rod is installed inside the conveying pipe and is coaxially mounted with the conveying pipe. A spiral blade is mounted around the transmission rod, and the outer side of the spiral blade contacts the inner wall of the conveying pipe.

[0007] The dispersing component includes a dispersing hopper, the upper end of which is connected to the inside of the conveying pipeline, and the lower end of which is connected to the inside of the processing chamber. The dispersing hopper is trapezoidal in shape, with the upper end being narrower than the lower end.

[0008] The dispersion hopper contains two primary dispersion blocks and two secondary dispersion blocks, with the primary dispersion blocks installed at a height that is vertically higher than the secondary dispersion blocks. The dispersion assembly includes a second power component, which is installed on one side of the dispersion hopper. The drive shaft of the second power component is rotatably connected to the primary dispersion block. Both the primary and secondary dispersion blocks have coaxially rotatably mounted connecting gears on one side, and the connecting gears are meshed.

[0009] The feeding assembly includes a recycling hopper, which is connected to the interior of the processing chamber. A feeding pipe is installed at the lower end of the recycling hopper, and the feeding pipe is connected to an external storage box.

[0010] The dust collection assembly includes a dust collection hopper, which is connected to the interior of the dust collection chamber. A dust collection pipe is installed at the lower end of the dust collection hopper, and the dust collection pipe is connected to external dust removal equipment.

[0011] This utility model has the following beneficial effects:

[0012] This invention drives the primary and secondary dispersing blocks to rotate, which disperses the feed materials entering the dispersing hopper. This disperses the feed materials that might otherwise be piled up. The trapezoidal structure of the dispersing hopper also helps the feed materials to gradually disperse during their fall, preventing them from piling up when entering the processing chamber. Furthermore, once the feed materials enter the processing chamber, the airflow from the fan can more effectively contact each part of the feed materials, blowing out fine impurities and improving the separation effect between impurities and feed materials, thus ensuring the processing quality of the feed materials.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0021] Please see Figure 1 , Figure 2 As shown:

[0022] This embodiment provides a raw material screening device for feed processing, including a processing box 1. A fine filter screen 2 is installed at an incline inside the processing box 1, dividing the interior of the processing box 1 into a processing chamber 3 and a dust collection chamber 4. A fan 5 is installed on one side of the processing chamber 3, with the airflow direction of the fan 5 perpendicular to the height direction of the processing chamber 3. A conveying pipe 6 is installed at the upper end of the processing box 1, and a conveying component 7 is installed inside the conveying pipe 6. The conveying component 7 is used for quantitative material conveying. A hopper 8 is installed at one end of the conveying pipe 6, and a dispersing component 9 is installed at the other end of the conveying pipe 6. The dispersing component 9 is used for dispersing materials. The lower end of the dispersing component 9 communicates with the interior of the processing chamber 3. A feeding component 10 and a dust collection component 11 are installed at the lower end of the processing box 1. The feeding component 10 communicates with the interior of the processing chamber 3, and the dust collection component 11 communicates with the interior of the dust collection chamber 4.

[0023] In actual operation, feed ingredients are poured from the hopper 8 into the conveying pipe 6. Driven by the conveying component 7, the feed ingredients are transported within the conveying pipe 6 to the dispersing component 9. This ensures that the feed ingredients are quantitatively and efficiently delivered to the dispersing component 9, preventing blockages. The dispersing component 9 disperses the delivered feed ingredients, ensuring they enter the processing chamber 3 evenly and preventing accumulation. The feed ingredients falling into the processing chamber 3 are supported by the force of the fan 5. This process blows fine impurities and dust from inside the feed ingredients through the fine filter screen 2 into the dust collection bin 4. The fine filter screen 2 also prevents the feed ingredients from being blown into the dust collection bin 4 by the wind. Then, the feed ingredients without impurities fall into the feeding component 10, which outputs the feed ingredients to the outside. The fine impurities and dust that have entered the dust collection bin 4 can be discharged to the outside of the device through the dust collection component 11, thereby effectively separating the fine impurities inside the feed ingredients from the inside and thoroughly separating the feed ingredients from the fine impurities.

[0024] like Figure 1 , Figure 2 As shown, the conveying assembly 7 includes a first power component 12, which is installed at one end of the conveying pipe 6. A transmission rod 13 is coaxially mounted on the drive end of the first power component 12. The transmission rod 13 is installed inside the conveying pipe 6 and is coaxially mounted with the conveying pipe 6. A spiral blade 14 is mounted around the transmission rod 13, and the outer side of the spiral blade 14 contacts the inner wall of the conveying pipe 6. Thus, by driving the first power component 12, it causes the transmission rod 13 to rotate. As the transmission rod 13 rotates, the spiral blade 14 mounted on the transmission rod 13 also rotates. Because the outer side of the spiral blade 14 contacts the inner wall of the conveying pipe 6, the transmission rod 13 rotates. When feed ingredients enter the conveying pipe 6 through the hopper 8, they come into contact with the rotating spiral blades 14. The spiral structure of the spiral blades 14 will generate an axial thrust on the feed ingredients. As the spiral blades 14 rotate continuously, the feed ingredients will move along the spiral path of the spiral blades 14 from the feed end (near the hopper 8) to the discharge end (near the dispersing component 9) of the conveying pipe 6, and enter the dispersing component 9 in an orderly manner for subsequent processing. This achieves the goal of quantitatively conveying the feed ingredients into the dispersing component 9, avoiding excessive feed ingredients entering the dispersing component 9 and affecting the feed ingredient dispersing effect of the dispersing component 9.

[0025] The first power component 12 includes, but is not limited to, an electric motor and a geared motor.

[0026] like Figure 2 , Figure 4 , Figure 5As shown, the dispersion assembly 9 includes a dispersion hopper 15. The upper end of the dispersion hopper 15 communicates with the interior of the conveying pipe 6, and the lower end of the dispersion hopper 15 communicates with the interior of the processing chamber 3. The dispersion hopper 15 is trapezoidal in shape, with the upper end being narrower than the lower end. A primary dispersion block 16 and a secondary dispersion block 17 are rotatably mounted inside the dispersion hopper 15. There are two secondary dispersion blocks 17, and the installation height of the primary dispersion block 16 is vertically higher than that of the secondary dispersion block 17. The dispersion assembly 9 includes a second power component 18, which is mounted on one side of the dispersion hopper 15. The drive shaft of the second power component 18 is rotatably connected to the primary dispersion block 16. Connecting gears 19 are coaxially rotatably mounted on one side of both the primary dispersion block 16 and the secondary dispersion block 17. The connecting gears 19 mesh with each other, so that when the second power component 18 is driven... During operation, the second power component 18 drives the primary dispersion block 16 to rotate, thereby enabling the secondary dispersion block 17 to rotate simultaneously with the primary dispersion block 16 via the connecting gear 19. This allows the feed material to be dispersed and processed under the rotational motion of the primary and secondary dispersion blocks 16 and 17 after falling into the dispersion hopper 15. Feed material that might have been piled up is fully dispersed. The trapezoidal structure of the dispersion hopper 15 also helps the feed material to gradually disperse during its fall, preventing the feed material from piling up when entering the processing chamber 3. Furthermore, when the feed material enters the processing chamber 3, the airflow blown by the fan 5 can more effectively contact each part of the feed material, blowing out the fine impurities and improving the separation effect between impurities and feed material, thus ensuring the processing quality of the feed material.

[0027] The second power component 18 includes, but is not limited to, an electric motor or a geared motor.

[0028] like Figures 1-3 As shown, the feeding assembly 10 includes a recovery hopper 20, which is connected to the interior of the processing chamber 3. A feeding pipe 21 is installed at the lower end of the recovery hopper 20, and the feeding pipe 21 is connected to an external storage box so that the processed feed raw materials can fall into the recovery hopper 20, enter the feeding pipe 21 through the recovery hopper 20, and be transported to the external storage box for storage through the feeding pipe 21.

[0029] like Figures 1-3 As shown, the dust collection assembly 11 includes a dust collection hopper 22, which is connected to the interior of the dust collection chamber 4. A dust collection pipe 23 is installed at the lower end of the dust collection hopper 22, and the dust collection pipe 23 is connected to an external dust removal device so that fine impurities and dust entering the dust collection chamber 4 can fall into the dust collection hopper 22, enter the dust collection pipe 23 through the dust collection hopper 22, and be collected into the external dust removal device through the dust collection pipe 23, thereby treating the impurities through the external dust removal device.

[0030] The working principle of the raw material screening device for feed processing provided by this utility model is as follows: The feed raw materials are poured from the feed hopper 8 into the conveying pipe 6. The first power component 12 drives the rotating rod to rotate. As the transmission rod 13 rotates, the spiral blade 14 rotates, so that the feed raw materials can move with the rotation of the spiral blade 14 and enter the dispersing hopper 15 in an orderly manner. When the feed raw materials fall into the dispersing hopper 15, they will be dispersed by the rotation of the primary dispersing block 16 and the secondary dispersing block 17. The feed raw materials that may have been piled up are fully dispersed. The trapezoidal structure of the dispersing hopper 15 also helps the feed raw materials to gradually disperse during the falling process, avoiding the accumulation of feed raw materials when entering the processing chamber 3. Then, when the feed raw materials enter the processing chamber 3, the airflow blown by the fan 5 can more effectively contact each part of the feed raw materials, blowing out the fine impurities, improving the separation effect of impurities and feed raw materials, and ensuring the processing quality of feed raw materials.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
