Description

Technical Field

[0001] This utility model relates to the field of cooling kiln technology, specifically to a cooling kiln device with iron removal function. Background Technology

[0002] A cooling kiln is a heat exchange device that transfers heat from high-temperature clinker to low-temperature gas. As a process equipment, it undertakes the task of rapidly cooling high-temperature clinker. As a thermal equipment, while rapidly cooling the clinker, it also undertakes the task of heating the secondary air entering the rotary kiln and the tertiary air entering the decomposition furnace.

[0003] Currently, most cooling kilns on the market are similar in overall structure to rotary kilns. However, compared to rotary kilns, they lack heating components. A fan is usually installed at the kiln inlet to blow air into the kiln cylinder, which, in conjunction with rotation, cools the material. In the rotary kiln calcination process of titanium-based materials, the presence of iron impurities can seriously affect the whiteness, purity, and application performance of the product. However, current cooling kilns are basically unable to further treat iron impurities during the cooling process and do not have the function of removing iron at the feed end.

[0004] Now, a novel cooling kiln device with iron removal function is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cooling kiln device with iron removal function to solve the problem mentioned in the background art of not having a function for easy iron removal at the feed end.

[0007] The feeding assembly includes a feeding cylinder, which is fixedly connected to the left side of the top of the bottom support frame. A discharge port is provided on the right side of the bottom of the feeding cylinder. A spiral feeding shaft is movably connected between the two sides inside the feeding cylinder. A servo motor is installed on the left side of the feeding cylinder. A raw material hopper and a loading hopper are fixedly connected to the left side of the bottom of the feeding cylinder.

[0008] As a further technical solution of this utility model, the small gear and the large gear ring mesh with each other, the drive motor drives the small gear to rotate continuously through the reducer, and the drive motor and the PLC controller are electrically connected.

[0009] As a further technical solution of this utility model, the right side of the feed cylinder extends into the interior of the rotary cylinder, and the interior of the feed cylinder and the discharge port are connected.

[0010] As a further technical solution of this utility model, the output end of the servo motor is connected to the left side of the screw feed shaft, and the servo motor and the PLC controller are electrically connected.

[0011] As a further technical solution of this utility model, a reduction motor is installed on the left side of the conveyor belt fixing frame, and an electromagnet is fixedly connected between the two sides inside the conveyor belt fixing frame. The distance between the front end of the electromagnet and the rear end of the magnetic roller is 0.5mm. The bottom ends of the magnetic roller and the electromagnet are flush. The output end of the reduction motor is connected to the magnetic roller. The magnetic roller, the reduction motor, the electromagnet, and the PLC controller are electrically connected.

[0012] As a further technical solution of this utility model, a brush support bracket is fixedly connected to the rear end of the top of the conveyor belt. A long brush is fixed to the top of the brush support bracket by bolts. The left and right sides of the long brush are flush with the left and right sides of the high-temperature resistant belt surface, and the top of the long brush is in contact with the bottom of the high-temperature resistant belt surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cooling kiln device with iron removal function not only realizes the function of easy iron removal at the feed end, but also realizes the function of iron removal at the tail end, and also realizes the function of reducing surface residue.

[0014] (1) By setting up a feed cylinder, discharge port, screw feeding shaft, servo motor, raw material hopper and loading hopper, when in use, titanium-based materials calcined by rotary kiln are introduced into the raw material hopper, and composite additives such as ammonium sulfate or ammonium carbonate are added into the loading hopper. The servo motor drives the screw feeding shaft to rotate continuously. The materials in the raw material hopper and loading hopper are initially mixed in the feed cylinder and enter the rotary cylinder along the discharge port, which promotes the conversion of iron in the material into soluble salts, which are then removed by water washing. The drive motor drives the small gear to rotate continuously through the reducer, and the large gear ring drives the rotary cylinder to rotate synchronously. When the rotary cylinder is installed, it is usually higher on the left and lower on the right. A blower is installed on its right side to send cold air into the rotary cylinder, which fully contacts the material and removes the heat, thus realizing the function of easy iron removal at the feed end.

[0015] (2) By setting up a conveyor belt fixing frame, magnetic roller, driven roller, high temperature resistant belt surface, geared motor, electromagnet and output conveyor belt, when in use, the cooled material is discharged along the right side of the rotating drum and falls on the high temperature resistant belt surface. The geared motor drives the high temperature resistant belt surface to rotate continuously through the magnetic roller, and conveys the material forward. When the material passes the position of the magnetic roller, the non-iron part flies forward under the action of inertia, and the iron part is attracted to the high temperature resistant belt surface and continues to move to the bottom of the electromagnet. After leaving the electromagnet area, it falls on the output conveyor belt and is collected separately, realizing the function of iron removal at the tail end.

[0016] (3) By setting up a brush support frame and a long brush, when in use, the long brush on the brush support frame fits against the bottom of the high temperature resistant belt surface and sweeps the bottom of it to clean the iron-containing substances remaining on the surface, thus realizing the function of reducing belt surface residue.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, titanium-based materials calcined in a rotary kiln are introduced into the raw material hopper 13, and composite additives such as ammonium sulfate or ammonium carbonate are added into the loading hopper 14. The servo motor 12 drives the screw feeding shaft 11 to rotate continuously. The materials in the raw material hopper 13 and the loading hopper 14 are initially mixed in the feed tube 9 and enter the rotary cylinder 2 along the discharge port 10, which promotes the conversion of iron in the material into soluble salts, which are then removed by subsequent water washing.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the cooled material is discharged along the right side of the rotary drum 2 and falls onto the high-temperature resistant belt 18.

The materials in the raw material hopper 13 and the loading hopper 14 are initially mixed in the feeding cylinder 9 and enter the rotary cylinder 2 along the discharge port 10, which promotes the conversion of iron in the material into soluble salts, which are then removed by water washing. The drive motor 3 drives the pinion 5 to rotate continuously through the reducer 4, and the large gear ring 8 drives the rotary cylinder 2 to rotate synchronously. When the rotary cylinder 2 is installed, it is usually higher on the left and lower on the right. A blower is installed on its right side to send cold air into the rotary cylinder 2, which fully contacts the material and removes the heat. The cooled material is discharged along the right side of the rotating drum 2 and falls onto the high-temperature resistant belt surface 18. The geared motor 19 drives the high-temperature resistant belt surface 18 to rotate continuously through the magnetic roller 16, conveying the material forward. When the material passes the position of the magnetic roller 16, the non-iron part flies forward under the action of inertia, while the iron-containing part is attracted to the high-temperature resistant belt surface 18 and continues to move to the area below the electromagnet 20. After leaving the area of ​​the electromagnet 20, it falls onto the discharge conveyor belt 21 and is collected separately.
