Description

Technical Field

[0001] The utility model relates to the technical field of metal processing auxiliary equipment, in particular to a decontamination device for special materials for ferrous metal smelting. Background Art

[0002] In the process of ferrous metal smelting, iron smelting is the main task, mainly using oxide ore as raw material. In the blast furnace, coke is used as a reducing agent, combined with the oxygen blown in, to reduce the oxide ore into pig iron. Pig iron contains a high carbon content, and oxygen is blown into the converter to oxidize the carbon, thereby obtaining steel. In this process, dust impurities are easily mixed into the raw materials.

[0003] Before putting into metal smelting, it is usually necessary to remove dust from the surface of raw materials such as coke. However, the existing decontamination device directly piles the coke in the decontamination container and extracts the dust on the surface of the coke through an exhaust fan. In this way, the coke is in a static state, and the inner layer of coke cannot be effectively cleaned, resulting in poor overall decontamination effect.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0035] See also Figures 1 to 5As shown, the embodiment of the present application provides a decontamination device for special materials for ferrous metal smelting, including: a decontamination component 3 and a support component 2, the decontamination component 3 includes a tank body 31, a driving mechanism 32 and a feeding part 33, the tank body 31 is cylindrical, and a feed port and a discharge port are respectively provided at both ends of the tank body 31. The tank body 31 rotates one circle to complete one discharge, and when the discharge port rotates to the bottom, the ferrous metal is discharged through the discharge port. The feeding part 33 is arranged on the inner wall of the tank body 31, and is spirally arranged along the length direction of the tank body 31 (the same as the spring structure), so that the feeding part 33 can drive the ferrous metal in the tank body 31 to move toward the discharge port during the rotation process. A plurality of leakage holes are evenly arranged on the circumference of the tank body 31, annular grooves are arranged on the circumferences of both ends of the tank body 31, an annular rack 8 is arranged in the annular groove near the end of the feed port, and the driving mechanism 32 is at least partially engaged with the annular rack 8 to drive the tank body 31 to rotate. The support assembly 2 is located below the tank body 31, and a first support wheel 6 and a second support wheel 9 are respectively arranged at both ends of the support assembly 2. There are at least two first support wheels 6 and second support wheels 9, and the first support wheel 6 can be rotatably arranged in the annular groove near the end of the feed port, and the first support wheel 6 is in contact with the annular rack 8, and the second support wheel 9 can be rotatably arranged in the annular groove near the end of the discharge port.

[0036] In the above scheme, the driving mechanism 32 and the annular rack 8 are arranged so that the driving mechanism 32 and the annular rack 8 are meshed, thereby driving the tank body 31 to rotate, flipping the ferrous metal entering the tank body 31, so that the dust adsorbed on the ferrous metal falls off and falls onto the support assembly 2 through the leak hole. During the rotation of the tank body 31, the feeding part 33 is also driven to rotate, so that the ferrous metal entering the tank body 31 can move along the length direction of the tank body 31, and thus be discharged through the discharge port, thereby effectively cleaning the dust on the surface of the ferrous metal, thereby improving the cleaning effect of the dust on the surface of the ferrous metal.

[0037] In some possible implementations, see Figure 1 and Figure 5As shown, the driving mechanism 32 includes a transmission mechanism, a driving gear 325 and a driving motor 321. One end of the transmission mechanism is sleeved on the output shaft of the driving motor 321, and the other end is sleeved on the central axis of the driving gear 325. The driving gear 325 is meshed and connected with the annular rack 8. The transmission mechanism includes a first driving wheel 323, a second driving wheel 322 and a transmission member 324. The first driving wheel 323 is sleeved on the central axis of the driving gear 325, and the second driving wheel 322 is sleeved on the output shaft of the driving motor 321. The transmission member 324 is sleeved on the first driving wheel 323 and the second driving wheel 322. The first driving wheel 323 and the second driving wheel 322 can be The first driving wheel 323 and the second driving wheel 322 are sprockets, and the transmission member 324 can be a chain or a belt. When the first driving wheel 323 and the second driving wheel 322 are sprockets, the transmission member 324 is a chain. When the first driving wheel 323 and the second driving wheel 322 are pulleys, the transmission member 324 is a belt. The diameter of the driving gear 325 is smaller than the diameter of the tank body 31, so that when the driving gear 325 drives the tank body 31 to rotate, a speed reduction mechanism is formed, which prolongs the turning time of the ferrous metal in the tank body 31, and can further clean the dust on the surface of the ferrous metal. At the same time, it also makes the rotation speed of the tank body 31 slower, and when the ferrous metal is discharged through the discharge port, more material can be discharged at one time.

[0038] In the above scheme, when it is necessary to remove dirt from the ferrous metal, the drive motor 321 is controlled to start. The drive motor 321 starts to drive the second drive wheel 322 to rotate through its output shaft, and drives the first drive wheel 323 to rotate under the action of the transmission member 324. The rotation of the first drive wheel 323 drives the drive gear 325 to rotate. The drive gear 325 engages with the annular rack 8, thereby driving the tank body 31 to rotate, thereby realizing the flipping of the ferrous metal in the tank body 31, causing the dust on the surface of the ferrous metal to fall off, and realizing the removal of dirt from the ferrous metal.

[0039] In some possible implementations, see Figure 1 and Figure 2 As shown, the feed port and the discharge port are respectively provided with a feed hopper 4 and a discharge hopper 5, and the feed hopper 4 and the discharge hopper 5 are arranged to be tilted downward from left to right to facilitate the entry and outflow of ferrous metal raw materials.

[0040] In some possible implementations, see Figure 1 and Figure 4 As shown, a strip groove is provided on the support component 2 along its length direction, a slidable pull rod 7 is provided in the strip groove, a pull ring is provided at one end of the pull rod 7 close to the feed hopper 4 to facilitate pulling the pull rod 7, and a scraper 10 is provided at one end of the pull rod 7 close to the discharge port, and the scraper 10 abuts against the inner wall of the support component 2.

[0041] In the above scheme, when long-term decontamination causes the dust on the surface of the ferrous metal to fall onto the inner surface of the support component 2, when cleaning the dust, the pull rod 7 is pulled by the pull ring to make the pull rod 7 slide toward one end close to the hopper 4, thereby driving the scraper 10 to slide, so that the scraper 10 scrapes off the dust on the inner surface of the support component 2 and pulls it out, which is convenient for centralized cleaning of the dust.

[0042] It should be noted that when cleaning the dust on the inner surface of the support component 2, it can also be flushed with a water gun, and the sewage from flushing flows out through the strip groove. Sewage discharge channels can also be connected at both ends of the strip groove to centrally treat the cleaned sewage.

[0043] In some possible implementations, see Figure 1 , Figure 2 and Figure 4 As shown, the special material decontamination device for ferrous metal smelting provided in the present application also includes a support structure 1, the support structure 1 has a support part 11, a platform 12 and a cross bar 13, the support assembly 2 is located on the support part 11, the drive motor 321 is arranged on the platform 12, and the drive gear 325 is rotatably arranged on the cross bar 13.

[0044] It should be noted that the support structure 1 also includes multiple supporting legs, the supporting part 11 is located between two supporting legs, and the inner surface of the supporting part 11 is in contact with the outer surface of the supporting assembly 2. The cross bar 13 is arranged between the two supporting legs for fixing and installing the driving gear 325. The platform 12 is horizontally arranged on the multiple supporting legs. The platform 12 is used to fix and install the driving motor 321. At the same time, the platform 12 can also be used as a temporary workbench or storage table.

[0045] By setting the driving mechanism 32 and the annular rack 8, the driving mechanism 32 is meshed with the annular rack 8, thereby driving the tank body 31 to rotate, flipping the ferrous metal entering the tank body 31, so that the dust adsorbed on the ferrous metal falls off and falls onto the support assembly 2 through the leak hole. During the rotation of the tank body 31, the feeding part 33 is also driven to rotate, so that the ferrous metal entering the tank body 31 can move along the length direction of the tank body 31, and thus be discharged through the discharge port, thereby effectively cleaning the dust on the surface of the ferrous metal, thereby improving the cleaning effect of the dust on the surface of the ferrous metal.

[0046] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
