Description

Technical Field

[0001] This application relates to the field of feed processing equipment, and in particular to a feed impurity screening device. Background Technology

[0002] The feed includes more than ten varieties 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 production and preparation process, impurities such as nails, screws, nuts, and stones inevitably get mixed into the feed. These impurities can cause processing equipment malfunctions, and in severe cases, may even cause motor stalling, leading to fires and serious safety hazards and economic losses.

[0003] Existing screening methods typically use vibrating screens, which are prone to clogging after prolonged use. Furthermore, when feed is pulverized into a flocculent structure, the screening effect for impurities will be greatly reduced. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a feed impurity screening device.

[0005] The feed impurity screening device provided in this application adopts the following technical solution: A feed impurity screening device includes a feed hopper, a discharge pipe installed at the lower part of the feed hopper, and the discharge pipe communicating with the feed hopper; a plurality of magnetic suction plates arranged at equal intervals are connected inside the discharge pipe.

[0006] A further technical solution is that the magnetic plate is an electromagnet, and the upper side of the magnetic plate has an arc surface structure.

[0007] A further technical solution is that the device also includes an air separator pipe, which has an air inlet, an air outlet, a feed inlet and a debris discharge outlet. The air inlet is connected to a fan, the feed inlet is connected to a discharge pipe, the debris discharge outlet is sealed to a collection bucket, and the air outlet is connected to a cyclone dust collector.

[0008] A further technical solution is that the air inlet of the air separator is lower than the height of the air outlet.

[0009] A further technical solution is that the upper end plate of the feeding hopper has a feeding port, and the side of the upper end plate facing the feeding port has a first receiving groove. A first door plate is slidably connected in the first receiving groove. A first cylinder parallel to the first door plate is installed on the upper end plate of the feeding hopper, and the piston rod of the first cylinder is connected to the first door plate. A partition is installed in the feeding hopper, and a discharge port is opened on the partition. A second receiving groove is opened on the side of the partition facing the discharge port. A second door plate is slidably connected in the second receiving groove. A second cylinder parallel to the second door plate is installed on the lower side of the second receiving groove, and the piston rod of the second cylinder is connected to the second door plate. The opening and closing states of the first door plate and the second door plate are always opposite.

[0010] A further technical solution is that the upper air outlet of the cyclone dust collector is connected to a circulating air duct, and the other end of the circulating air duct is connected to the air inlet of the fan.

[0011] Compared with the prior art, this application includes the following beneficial technical effects: By arranging equally spaced magnetic suction plates inside the discharge pipe, unscreened feed can be placed in the feed hopper and allowed to enter the discharge pipe directly. The feed can only pass through the gaps between the magnetic suction plates. When the feed contains impurities such as nuts and nails, they can be attracted by the magnetic suction plates. After the feed is discharged from the discharge pipe, the impurity screening is completed.

[0012] By connecting the air separator pipe, blower, and cyclone dust collector below the discharge pipe, the feed falling into the air separator pipe can be blown into the cyclone dust collector by the wind, and the feed can be discharged from the discharge port below the cyclone dust collector. Stones, glass, and other impurities in the feed can fall freely into the collection box by gravity, thereby achieving the screening and filtration of non-ferromagnetic impurities.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] The technical solutions in this application will be further described in detail below with reference to the accompanying drawings.

[0021] This application discloses a feed impurity screening device. Please refer to... Figure 1 The device includes a feeding bin 1, and a discharge pipe 11 is installed at the lower part of the feeding bin 1. The discharge pipe 11 is connected to the feeding bin 1. A plurality of magnetic suction plates 12 are connected inside the discharge pipe 11.

[0022] The specific screening process is as follows: After the unscreened feed is placed in the feed hopper 1, the feed directly enters the discharge pipe 11. Since the magnetic suction plates 12 are arranged at equal intervals in the discharge pipe 11, the feed can only pass through the gaps between the magnetic suction plates 12. When the feed contains impurities such as nuts and nails, they can be attracted by the magnetic suction plates 12. After the feed is discharged from the discharge pipe 11, the impurity screening is completed.

[0023] Furthermore, the magnetic accumulator 12 is an electromagnet, and the upper side of the magnetic accumulator 12 has an arc-shaped structure.

[0024] The upper side of the magnetic suction plate 12 has an arc-shaped structure, which reduces resistance to the feed and prevents the feed from accumulating on the upper side of the magnetic suction plate 12. The magnetic suction plate 12 is an electromagnet that can be de-energized after the impurity screening is completed, so that the ferromagnetic impurities adsorbed on the magnetic suction plate 12 can fall off automatically, eliminating the need for manual cleaning.

[0025] In some embodiments, please refer to Figure 2 and Figure 3 The device also includes an air separator 2, which has an air inlet 21, an air outlet 22, a feed inlet 23 and a waste discharge outlet 24. The air inlet 21 is connected to a fan 25, the feed inlet 23 is connected to a discharge pipe 11, the waste discharge outlet 24 is sealed to a collection bucket 26, and the air outlet 22 is connected to a cyclone dust collector 27.

[0026] Besides ferromagnetic impurities such as iron nails, feed inevitably contains non-ferromagnetic impurities such as stones and glass. By connecting the air separator 2 to the bottom of the discharge pipe 11, the feed enters the air separator 2 after being discharged from the discharge pipe 11. Under the action of the wind generated by the blower 25, the lighter feed will be discharged from the air outlet 22 with the wind force and enter the cyclone dust collector 27, so that the feed is discharged from the bottom of the cyclone dust collector 27. Meanwhile, impurities such as stones and glass shards in the feed will fall freely and fall from the waste discharge port 24 into the collection bucket 26.

[0027] After screening is completed, the blower 25 stops working, the magnetic plate 12 loses its magnetism due to power failure, and the ferromagnetic impurities adsorbed on the magnetic plate 12 will fall directly from the discharge port 24 into the collection bucket 26, further improving the convenience of impurity screening.

[0028] In some embodiments, the air inlet 21 of the air separator 2 is lower than the height of the air outlet 22.

[0029] The air inlet 21 is lower than the air outlet 22, which allows heavier objects in the feed to roll down along the air separator 2, while the feed is discharged towards the higher air outlet 22 by the wind force of the fan 25, thereby achieving the separation of impurities and feed.

[0030] Further, please refer to Figure 4 The upper end plate of the feeding hopper 1 has a feeding port 31, and a first receiving groove 32 is formed on the side of the upper end plate facing the feeding port 31. A first door plate 33 is slidably connected in the first receiving groove 32. A first cylinder 34 parallel to the first door plate 33 is installed on the upper end plate of the feeding hopper 1, and the piston rod of the first cylinder 34 is connected to the first door plate 33. A partition 4 is installed in the feeding hopper 1, and a discharge port 41 is formed on the partition 4. A second receiving groove 42 is formed on the side of the partition 4 facing the discharge port 41. A second door plate 43 is slidably connected in the second receiving groove 42. A second cylinder 44 parallel to the second door plate 43 is installed on the lower side of the second receiving groove 42, and the piston rod of the second cylinder 44 is connected to the second door plate 43. The opening and closing states of the first door plate 33 and the second door plate 43 are always opposite.

[0031] Since the feed hopper 1 is connected to the air separator pipe 2 through the discharge pipe 11, the air force in the air separator pipe 2 will enter the feed hopper 1 through the discharge pipe 11. By setting the first door plate 33 and the second door plate 43 in the feed hopper 1, the air force can be prevented from leaking out of the feed hopper 1.

[0032] Specifically, when the first cylinder 34 is in the retracted state, the first door plate 33 retracts into the first receiving tank 32, and the feeding port 31 is open. At this time, the second cylinder 44 is in the extended state, the second door plate 43 extends out of the first receiving tank 32, and the feeding port 41 is closed. Feed can then be added to the feed hopper 1 through the feeding port 31. When there is no feed in the compartment below the partition 4, the first cylinder 34 extends first, causing the first door plate 33 to close the feeding port 31. After the first door plate 33 completely closes the feeding port 31, the second cylinder 44 retracts, causing the second door plate 43 to open the feeding port 41. The feed above the partition 4 can then fall downwards through the feeding port 41 and enter the discharge pipe 11 for screening and filtration. The entire process prevents airflow from leaking from the feed hopper 1 within the air separator.

[0033] Furthermore, both the partition 4 and the second door panel 43 are inclined towards the feed inlet 41. This allows the feed to fall down the slope on the partition 4 after the second door panel 43 is opened, preventing the feed from accumulating on the partition 4.

[0034] Furthermore, the upper air outlet 22 of the cyclone dust collector 27 is connected to a circulating air duct 5, and the other end of the circulating air duct 5 is connected to the air inlet of the fan 25, such as... Figure 4 As shown.

[0035] After the air is discharged from the exhaust port above the cyclone dust collector 27, it is reconnected to the air inlet port of the fan 25 through the circulating air duct 5, which can effectively reduce the energy consumption of the fan 25 and improve the air separation efficiency.

[0036] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
