Description

Technical Field

[0001] This utility model belongs to the field of powder iron removal technology, and in particular relates to a pneumatic powder iron removal device. Background Technology

[0002] Iron removal from powder is a device specifically designed to remove ferromagnetic impurities from powder or fine granular materials. Its working principle is based on electromagnetic induction and magnetic field attraction. It uses a high-intensity magnetic field to adsorb ferromagnetic metal impurities, ensuring the purity of the material, protecting production equipment, and improving product quality.

[0003] The existing utility model with authorization announcement number CN215917794U discloses a powdered fluid iron removal device, including a screening main box, a magnetic screening device is arranged inside the screening main box, a powdering adjustment device is arranged above the magnetic screening device, the magnetic screening device includes a fixed magnetic frame, an electromagnet is embedded and fixedly connected at the center of the upper surface of the fixed magnetic frame, and a charging interface is fixedly connected at the lower surface of the fixed magnetic frame, and the charging interface is electrically connected to the electromagnet through a wire.

[0004] By adopting the above technical solution and setting a bottom screen, the powdered fluid can be dispersed and evenly fall onto the surface of the electromagnet, so that the iron powder can fully contact the electromagnet, the iron powder can be fully attracted, and the iron powder can be fully removed with high removal efficiency and high degree of mechanization. However, the above technical solution can only facilitate the absorption of iron filings in the powder. When too many iron filings and impurities are adsorbed on the electromagnet, the absorption effect of iron filings is reduced, and the electromagnet cannot be cleaned quickly, which can easily lead to the problem of reduced iron filings absorption efficiency.

[0005] Therefore, we propose a pneumatic powder iron removal device to solve the above problems. Utility Model Content

Therefore, a pneumatic powder iron removal device is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

A sliding plate and several [unclear - possibly referring to components or components] are fixedly connected to the bottom surface of the movable plate. The sliding plate has several identical sleeves fixedly connected to the bottom surface of the second hydraulic telescopic rods. The telescopic ends of the four sets of second hydraulic telescopic rods are fixedly connected to scrapers. Several identical heating rods are fixedly connected to the inner wall of the conveying pipe.

[0010] Preferably, each butterfly valve has a fixed bracket fixedly connected to its outer surface, and the bottom surface of each fixed bracket is fixedly connected to the upper surface of the conveying pipeline.

[0011] Preferably, two protective seats are fixedly connected to the outer surface of each group of the first hydraulic telescopic rod, and the bottom surface of each group of the protective seats is fixedly connected to the upper surface of the L-shaped fixing plate.

[0012] Preferably, two reinforcing plates are fixedly connected to the outer surface of the telescopic end of each group of the first hydraulic telescopic rod, and the upper surface of each reinforcing plate is fixedly connected to the bottom surface of the movable plate.

[0013] Preferably, the inner wall of each set of reinforcing plates is threaded with several identical limiting bolts, and the outer surface of each set of limiting bolts is threaded to the inner wall of the movable plate.

[0014] Preferably, two dustproof shells are fixedly connected to the outer surface of each group of the second hydraulic telescopic rods, and the upper surface of each dustproof shell is fixedly connected to the bottom surface of the movable plate.

[0015] Preferably, a reinforcing frame is fixedly connected to the outer surface of the control panel, and the back of the reinforcing frame is fixedly connected to the front of the conveying pipe.

Compared with traditional electromagnets, it can work continuously without power, reducing energy consumption and avoiding the falling of iron filings due to power failure. The scraper is driven to move up and down by the second hydraulic telescopic rod, which can quickly remove the iron filings adsorbed on the surface of the sleeve, solving the problem of reduced efficiency of electromagnets after adsorbing iron filings in the existing technology.

[0020] 2. The heating rods on the inner wall of the conveying pipe, in conjunction with the heat-conducting plate, can uniformly heat the powder, reduce its stickiness, and make it easier for iron filings to separate from the powder. This is especially suitable for iron removal scenarios involving damp or sticky powders. The fan inside the baffle, in conjunction with the filter screen, can create airflow during powder conveying, blowing away agglomerated powder particles. At the same time, the filter bag collects dust in the airflow, preventing dust from overflowing and improving the cleanliness of the working environment. The sealed airbag, after being inflated by the air pump, fits tightly against the inner wall of the baffle. Combined with the filter box, it effectively prevents external dust from entering the conveying pipe, ensuring the purity of the powder and avoiding secondary pollution. Attached Figure Description

The telescopic ends of the two sets of first hydraulic telescopic rods 16 are fixedly connected to a movable plate 15. Two protective seats 17 are fixedly connected to the outer surface of each set of first hydraulic telescopic rods 16.

[0035] The bottom surface of the movable plate 15 is fixedly connected to a sliding plate 22 and several identical second hydraulic telescopic rods 23. The bottom surface of the sliding plate 22 is fixedly connected to several identical sleeves 19. The outer surface of the telescopic end of each group of first hydraulic telescopic rods 16 is fixedly connected to two reinforcing plates 20.

[0038] Several identical permanent magnet rods 28 are fixedly connected to the bottom surface of the movable frame 26. Several identical grooves 18 are opened on the upper surface of the movable plate 15 and the upper surface of the sliding plate 22. A sealing airbag 31 is fixedly connected to the inner wall of the conveying pipe 1. An air pump 32 is fixedly connected to the outer surface of the sealing airbag 31. The outer surface of the sealing airbag 31 is in contact with the inner wall of the baffle 8. Through the sealing airbag 31 and the air pump 32, the contact point between the baffle 8 and the conveying pipe 1 can be sealed to prevent external dust and impurities from entering the conveying pipe 1.

[0039] The inner wall of each groove 18 is in contact with the outer surface of the permanent magnet 28. The input end of the air pump 32 is fixedly connected to the filter box 30. The bottom surface of the filter box 30 is fixedly connected to the upper surface of the conveying pipe 1. Through the filter box 30, the air entering the air pump 32 can be filtered to prevent the air pump 32 from being affected by impurities, which would reduce its service life.

[0040] The working principle of this utility model is as follows: When in use, the powder is first introduced from the storage tank 2 into the conveying pipe 1 through the butterfly valve 12. It flows in the pipe. The permanent magnet 28 at the bottom of the movable frame 26 generates a strong magnetic field, which adsorbs the ferromagnetic impurities in the powder and makes them adhere to the surface of the sleeve 19. The fan 10 in the baffle 8 is started, and an airflow is formed through the filter screen 9 to blow away the agglomerated powder particles. At the same time, the filter bag 29 collects the dust in the airflow to avoid pollution. The heating rod 7 on the inner wall of the conveying pipe 1 cooperates with the heat-conducting plate 14 to heat the powder evenly, reduce the stickiness of the powder, and make it easier for iron filings to separate from the powder. It is especially suitable for wet or sticky powders.

[0041] When a large amount of iron filings adsorbed on the surface of the sleeve 19 needs to be cleaned, the extension end of the first hydraulic telescopic rod 16 is extended, driving the movable plate 15 to rise. This causes the sleeve 19 and the permanent magnet rod 28 to rise above the conveying pipe 1. Then, the iron filings collection box is placed below the sleeve 19, and the extension end of the third hydraulic telescopic rod 27 is extended to pull the permanent magnet rod 28 out of the sleeve 19. Next, the second hydraulic telescopic rod 23 drives the scraper 25 to move up and down to scrape off the iron filings, causing them to fall into the collection box. This process effectively collects the iron filings and solves the problem of reduced adsorption efficiency of traditional electromagnets.
