[0031] like Figure 1 、 Figure 3 As shown, a deironing device for vacuum feeding includes a vacuum feeding part 1 and a discharge part 2 connected to the bottom of the vacuum feeding part 1, the discharge part 2 is fixedly connected to a support frame 3, the vacuum feeding part 1 is provided with two parallel vacuum generators 7, and a deironing component 4 is provided inside the discharge part 2. The vacuum feeding part 1 and the deironing component 4 are both sealed structures. An observation window 204 is provided on the side wall of the discharge part 2. The position of the observation window 204 matches the position of the deironing component 4. A glass plate is fixedly installed on the outside of the observation window 204. The glass plate is made of organic glass and can observe the thickness of iron impurities adsorbed on the magnetic row in real time, so as to remove the iron impurities adsorbed on the magnetic row in time and ensure the deironing effect on the material. The bottom of the discharge part 2 is connected to a material outlet 201 and an impurity removal outlet 202.

[0032] As the title 1, Figure 4 As shown, the iron removal component 4 includes multiple magnetic rod components 401, and multiple magnetic rod components 401 are installed in parallel on the mounting plate. The mounting plate is connected to a reduction motor 403 through a rotating shaft. The reduction motor 403 can drive the mounting plate to rotate, thereby causing the multiple magnetic rod components 401 to rotate, increasing the contact area between the magnetic rod components 401 and the material, and improving the adsorption efficiency of iron impurities; the reduction motor 403 is placed on the outside of the discharge part 2, and a motor bracket 405 is provided at the bottom of the reduction motor 403. The motor bracket 405 is fixedly connected to the support frame 3, which can make the reduction motor 403 rotate. The motor 403 is more stable, thereby improving the stability of the entire equipment; multiple magnetic rod assemblies 401 are sleeved with a debris removal scraper 402, and the debris removal scraper 402 is sleeved on the side of the mounting plate close to the reduction motor 403. The debris removal scraper 402 is connected to a debris removal cylinder 404, and the output end of the debris removal cylinder 404 passes through the mounting plate and is fixedly connected to the center position of the debris removal scraper 402. The debris removal scraper 402 can be driven to move in the horizontal direction through the extension and contraction of the debris removal cylinder 404, which can scrape off iron impurities adsorbed on the surface of the magnetic rod assembly 401, reducing the difficulty of cleaning the magnetic rods.

[0033] A reversing baffle 203 is provided above the material outlet 201 and the impurity removal outlet 202. The reversing baffle 203 is connected to the reversing cylinder 6. The output end of the reversing cylinder 6 is connected to a remote rod 601. The remote rod 601 is coaxially connected to the rotating axis of the reversing baffle 203. The other side of the reversing cylinder 6 is fixedly connected to the support frame 3 through a mounting seat. The extension and retraction of the reversing cylinder 6 drives the remote rod 601 to rotate, thereby driving the reversing baffle 203 to rotate along the rotating axis to the other side wall of the discharge part 2, completing the conversion of the discharge port.

[0034] like Figure 1 、 Figure 2 As shown, the vacuum feeding part 1 includes a hopper upper section 101, a rotary cylinder section 102 and a hopper bottom section 103. The top of the hopper upper section 101 is connected to a hopper cover 104. Two vacuum generators 7 are symmetrically arranged on both sides of the hopper upper section 101. The hopper cover 104 is connected to an electronic negative pressure gauge 8. In this embodiment, the vacuum feeding part adopts a circulating feeding method. The outer wall of the rotary cylinder section 102 is provided with a silicone breathing port. The interior of the rotary cylinder section 103 is provided with a door panel. The door panel is connected to a fan-shaped cylinder. When sucking materials, the fan-shaped cylinder drives the inner door panel of the rotary cylinder section 102 to rotate, so that the upper part of the vacuum feeding part 1 is sealed. Under the drive of the vacuum generator 7, negative pressure is formed. The material is sucked into the loader; when discharging the material, the fan-shaped cylinder drives the door panel to rotate, so that the material in the vacuum feeding part 1 falls into the hopper bottom section 103 and the iron removal component 4; since the vacuum feeding part 1 and the iron removal component 4 are in a sealed state, when the material quickly enters the iron removal component 4, the pressure inside and outside the cavity is adjusted through the silicone breathing port, and an equal volume of air is discharged; a filter component 5 is provided inside the hopper upper section 101, and the filter component 5 includes a filter plate 501 provided on the top of the hopper upper section 101, and a plurality of filter rods 502 are provided in parallel at the bottom of the filter plate 501 to remove dust from the equipment and reduce the dust content during the use of the equipment.

[0035] When the present invention is in use, the vacuum feeding part 1 is connected to two vacuum generators 7 in parallel. In the default state, only one vacuum generator 7 is working. The negative pressure situation is monitored online by the electronic negative pressure meter 8, and the second vacuum generator 7 is started in time to achieve higher suction force to meet the needs of materials with larger specific gravity or larger output; when sucking materials, the fan-shaped cylinder drives the door panel inside the rotary cylinder section 102 to rotate, so that a seal is formed on the upper part of the vacuum feeding part 1, and negative pressure is formed under the drive of the vacuum generator 7, so that the material is sucked into the feeding machine; when discharging materials, the fan-shaped cylinder drives the door panel to rotate, so that the material in the vacuum feeding part 1 falls into the hopper bottom section 103 and the iron removal component 4. Since the vacuum feeding part 1 and the iron removal component 4 are in a sealed state, when the material quickly enters the iron removal component 4, the pressure inside and outside the cavity is adjusted through the silicone breathing port, and an equal volume of air is discharged; after passing through the vacuum feeding part 1, the material falls into the discharge part 2, and the reversing baffle 203 is placed on the left side of the discharge part 2. The material is discharged from the material outlet 201, and the reduction motor 403 drives the magnetic rod component 401 to rotate, fully contacting with the material, and adsorbing iron impurities in the material. The thickness of the iron impurities adsorbed on the surface of the magnetic rod component 401 is observed through the observation window 204. If the thickness is large, the feeding is suspended and the reversing air is used to adjust the pressure. The cylinder 6 rotates the reversing baffle 203 to the right side of the discharge part 2, closes the discharge material outlet 201, starts the impurity removal cylinder 404 to drive the impurity removal scraper 402 to move left and right, removes the iron impurities on the surface of the magnetic rod assembly 401, and the iron impurities fall downward and are discharged through the iron impurity outlet 202 without affecting the material quality. After the magnetic rod assembly 401 is cleaned, the impurity removal scraper 402 is restored, and the reversing cylinder 6 rotates the reversing baffle 203 to the left side of the discharge part 2 to close the iron impurity outlet 202, and re-loads the material through the vacuum loading part 1. The material passes through the iron removal assembly again and is discharged through the material outlet 201.

However, the above contents are only preferred embodiments of the present invention and should not be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
