Description

Technical Field

[0001] This utility model belongs to the field of feed processing equipment, and in particular relates to a feed raw material impurity removal device. Background Technology

[0002] Animal feed processing first requires impurity removal to remove impurities such as metal, sand, and plastic from the raw materials. For granular or lumpy grain feed raw materials such as corn, wheat, and rice, a rotary screen is usually used for preliminary screening and impurity removal. During the impurity removal process, stones, sand, metal fragments, etc. filtered by the screen can easily get stuck in the screen gaps. Over time, this causes the screen screening efficiency to decrease, and qualified materials cannot be effectively separated from impurities. This results in feed being mixed with impurities, requiring frequent shutdowns to clean the screen, increasing labor maintenance costs and reducing work efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a feed raw material impurity removal device to solve the technical problem that during the impurity removal process, stones, sand, metal fragments and other materials filtered by the screen are easily stuck in the gaps of the screen. After long-term use, the screen screening and impurity removal efficiency decreases, qualified materials cannot be effectively separated from impurities, and feed is mixed in with impurities. This requires frequent shutdowns to clean the screen, increases manual maintenance costs and reduces work efficiency.

[0004] To achieve the above objectives, the specific technical solution of this utility model feed ingredient impurity removal device is as follows:

[0005] A feed ingredient impurity removal device includes a frame; a screen cylinder is rotatably mounted on the frame; the screen cylinder is tilted and rotatably mounted on the frame with one end higher than the other; the screen cylinder includes a rotating shaft rotatably mounted on the frame; multiple cross-shaped support plates are mounted on the rotating shaft; a fixing ring is fixedly mounted on the support plate at the end away from the rotating shaft; multiple connecting columns are equidistantly arranged circumferentially on the inner wall of the fixing ring; a motor is fixedly mounted on the upper end of the frame at the screen cylinder; the motor drives the rotating shaft to rotate; a material outlet is located on the lower side of the frame relative to the screen cylinder; an impurity outlet is located on the lower side of the frame relative to the screen cylinder; a material inlet is located on the upper side of the frame relative to the screen cylinder, extending into the screen cylinder; a cleaning roller is rotatably mounted on one side of the frame parallel to the screen cylinder; multiple cleaning protrusions are equidistantly arranged on the outer surface of the cleaning roller; the gaps between the cleaning protrusions and two adjacent connecting columns are opposite; a pulley group is fixedly mounted on the rotating shaft near the motor; a first pulley is fixedly mounted on the cleaning roller relative to the pulley group; the first pulley and the pulley group are connected by a drive belt.

[0006] Furthermore, the cleaning roller is provided with an avoidance groove at a position relative to the fixed ring.

[0007] Furthermore, a brush roller is rotatably mounted on the side of the screen cylinder opposite to the cleaning roller; a second pulley is fixedly mounted on the brush roller relative to the pulley assembly; and a drive belt connects the second pulley to the pulley assembly.

[0008] This utility model of feed ingredient impurity removal device has the following advantages: A cleaning roller is rotatably mounted on one side of the screen cylinder. Simultaneously with the rotation of the motor-driven shaft, the first pulley, driven by a pulley assembly and drive belt, rotates the cleaning roller synchronously with the screen cylinder. Cleaning protrusions on the outer side of the cleaning roller clean the gaps between the connecting columns of the screen cylinder, pushing sand, stones, and other debris stuck between the two connecting columns back into the screen cylinder, thus clearing the blockage. The cleaning roller, rotating synchronously with the screen cylinder, can promptly remove blockages, stabilizing the screening accuracy of feed ingredients and reducing... This design reduces the frequency of downtime for cleaning and increases the efficiency of feed impurity removal. A brush roller is rotatably installed on one side of the screen cylinder. When the motor drives the shaft to rotate, the pulley assembly and drive belt drive the second pulley to rotate the brush roller. The brush roller cleans the screen cylinder, and the brush can reach between the two connecting columns of the screen cylinder to effectively remove dust, debris, and light fibers adhering to the screen cylinder. This effectively increases the air permeability of the screen cylinder, reduces the frequency of manual cleaning, and works in conjunction with the cleaning roller to remove sand and stones that clog the screen cylinder, effectively increasing the efficiency and accuracy of impurity removal and screening of feed raw materials.

Detailed Implementation

[0014] To better understand the purpose, structure, and function of this utility model, the feed ingredient impurity removal device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0015] like Figures 1-4 As shown, the feed raw material impurity removal device of this utility model includes a frame 1; a screen cylinder 2 is rotatably mounted on the frame 1; the screen cylinder 2 is tilted and rotatably mounted on the frame 1 with one end higher than the other end; the screen cylinder 2 includes a rotating shaft 3 rotatably mounted on the frame 1; multiple cross-shaped support plates 4 are mounted on the rotating shaft 3; a fixing ring 5 is fixedly mounted on the end of the support plate 4 away from the rotating shaft 3; multiple connecting columns 6 are equidistantly arranged on the inner wall of the fixing ring 5; a motor 7 is fixedly mounted on the upper end of the frame 1 at the screen cylinder 2; the motor 7 drives the rotating shaft 3 to rotate; a material outlet 8 is provided on the lower side of the frame 1 relative to the screen cylinder 2; a material outlet 8 is provided on the lower side of the frame 1 at the screen cylinder 2. An impurity outlet 9 is provided at a relative position at one end of the frame 1; a material inlet 10 is provided at a relative position at one end of the upper side of the screen cylinder 2, extending into the screen cylinder 2; a cleaning roller 11 is provided on one side of the frame 1 parallel to the screen cylinder 2 and rotates therein; multiple cleaning protrusions 12 are provided at equal intervals on the outer surface of the cleaning roller 11; the gap between the cleaning protrusions 12 and the gap between two adjacent connecting columns 6 is opposite; a pulley group 13 is fixedly provided on the rotating shaft 3 at a position close to the motor 7; a first pulley 14 is fixedly provided on the cleaning roller 11 at a position relative to the pulley group 13; the first pulley 14 and the pulley group 13 are connected by a drive belt 15.

[0016] Combination Figures 1-4 As shown, during operation, feed ingredients are fed into the screen cylinder 2 through the material inlet 10. The motor 7 is started, driving the rotating shaft 3 to rotate. The rotating shaft 3, via the support plate 4, drives the fixed ring 5 and connecting columns 6 to rotate, causing the feed ingredients inside the screen cylinder 2 to rotate with it. During rotation, the feed ingredients move from the higher end of the screen cylinder 2 to the lower end. Simultaneously, a screen is formed by the gaps between the multiple connecting columns 6 to sieve and remove impurities from the feed ingredients. Smaller feed ingredients pass through the gaps between the multiple connecting columns 6 and are discharged from the material outlet 8. The filtered stones and gravel continue to move downwards within the screen cylinder 2 and are finally discharged through the impurity outlet 9. During the impurity removal process, appropriately sized stones and gravel are easily trapped. A blockage forms in the gap between the two connecting columns 6 in the screen cylinder 2. While the motor 7 drives the rotating shaft 3 to rotate, the pulley group 13 and the drive belt 15 drive the first pulley 14 to drive the cleaning roller 11 to rotate synchronously with the screen cylinder 2. The cleaning protrusions 12 on the outside of the cleaning roller 11 clean the gap between the connecting columns 6 of the screen cylinder 2, pushing the sand, stones and other particles stuck between the two connecting columns 6 and blocking the screen cylinder 2 back into the screen cylinder 2. Then, they move down and are discharged through the impurity outlet 9, thus completing the cleaning of the blockage in the screen cylinder 2. The cleaning roller 11, which rotates synchronously with the screen cylinder 2, can clean the blockage in the screen cylinder 2 in a timely manner, stabilize the screening accuracy of feed raw material impurity removal, reduce the frequency of downtime for cleaning, and increase the working efficiency of feed impurity removal.

[0017] The cleaning roller 11 has an avoidance groove 16 at a position relative to the fixing ring 5. The cleaning roller 11 is in contact with the screen cylinder 2. Multiple cleaning protrusions 12, which are equidistantly arranged on the outer surface of the cleaning roller 11, extend into the gap between two adjacent connecting columns 6. This is to push away the stones and gravel stuck between the two adjacent connecting columns 6 using the cleaning protrusions 12. At the same time, the fixing ring 5 on the screen cylinder 2 can be inserted into the avoidance groove 16 on the cleaning roller 11 to prevent it from affecting the cleaning operation of the cleaning roller 11.

[0018] A brush roller 17 is rotatably mounted on the side of the screen cylinder 2 opposite to the cleaning roller 11. A second pulley 18 is fixedly mounted on the brush roller 17 relative to the pulley group 13. A drive belt 15 is connected between the second pulley 18 and the pulley group 13. The brush roller 17 is rotatably mounted on the side of the screen cylinder 2. When the motor 7 drives the rotating shaft 3 to rotate, the pulley group 13 and the drive belt 15 drive the second pulley 18 to rotate the brush roller 17. The brush roller 17 is used to clean the screen cylinder 2. The brush can extend into the position between the two connecting columns 6 of the screen cylinder 2 to effectively remove dust, debris and light fibers adhering to the screen cylinder 2, effectively increase the air permeability of the screen cylinder 2, reduce the frequency of manual cleaning, and work with the cleaning roller 11 to clean the sand and stones that are stuck in the screen cylinder 2, effectively increasing the efficiency and accuracy of the screening of feed raw materials.
