Description

Technical Field

[0001] This utility model belongs to the field of red mud treatment technology, and specifically relates to an integrated machine for red mud treatment, grinding, screening and mixing. Background Technology

[0002] Red mud, as a byproduct of the aluminum industry, is a polluting waste residue for the natural environment. The common method of treating red mud is to stockpile it, but ordinary stockpiling will pollute the soil and water sources. As an improved treatment solution, it is now often processed by grinding and mixing to make fertilizer or to fire bricks, so as to achieve resource reuse.

[0003] A search of existing technologies revealed a red mud treatment grinding, screening and mixing integrated machine with announcement number CN222369265U, which discloses a treatment scheme for red mud. In this scheme, the added ingredients, wood ash and humic acid, are mixed with red mud through a stirrer to make fertilizer for reuse.

[0004] The agitator in the above solution has a drawback in application. After the ingredients are added, they will gradually sink through agitation. During the sinking process, it is difficult to stir the ingredients to rise again, which will result in the ingredients accumulating at the bottom and causing uneven mixing.

[0005] Based on existing technology and the aforementioned drawbacks, the applicant provides an integrated machine for treating red mud that can mix it evenly. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an integrated machine for grinding, screening and mixing red mud, which can perform integrated processing of crushing, screening and mixing of red mud, and the mixing component can ensure relatively uniform mixing.

[0009] The mixing mechanism includes a mixing box, with first through slots on both sides of the mixing box and second through slots on the other two sides of the mixing box.

[0010] The mixing chamber has a first slide rail on its inner wall and a second slide rail on its outer wall. A diversion block is located inside the mixing chamber, with both ends of the diversion block fixedly connected to the inner wall of the mixing chamber. A tray is inserted into the first through slot and supported by the first and second slide rails. An electric push rod is located above the tray and is fixed to the outer wall of the mixing chamber. The top shaft of the electric push rod is fixedly connected to the tray. The electric push rod drives the tray to slide on the first and second slide rails and press against the diversion block to divert and block the flow in the mixing chamber. The mixing chamber is also supported by legs.

[0011] The mixing chamber contains two sets of mixing components located on either side of the diversion block. Each mixing component has two ends positioned within a second through-slot and includes a main shaft, a stirring shaft, a second sealing plate, an internal gear disc, a fixing frame, and a second motor. The main shaft has a fan plate and is located within the second through-slot. The second sealing plate is fixedly connected to both ends of the main shaft, sealing the second through-slot to prevent material leakage. The stirring shaft is located on one side of the fan plate and is rotatably connected to the second sealing plate at both ends. A gear is located at the end of the stirring shaft. The fixing frame is fixed to the outer wall of the mixing chamber and is rotatably connected to both ends of the main shaft. A fixing block is located on the internal gear disc and is located on one side of the fixing frame, fixedly connected to the fixing frame via the fixing block. The internal gear disc meshes with the gear on the stirring shaft. The second motor is fixed to the fixing frame, and its output shaft is connected to the main shaft. A feed inlet is located on the top side wall of the mixing chamber for adding ingredients, including wood ash and humic acid. Furthermore, the fan plate has through holes to allow for material flow through one side of the fan plate during the mixing process.

[0012] The screening mechanism includes a screening box, a first sealing plate, a second guide plate, a support platform, a screening plate, a third motor, and a rotating shaft. One end of the screening box is fixedly connected to a mixing box by bolts. A discharge port is provided on one side of the screening box. A guide rail and a second electric push rod are provided on the side wall of the screening box. Both ends of the first sealing plate are located inside the guide rail. The top shaft of the second electric push rod is fixedly connected to the first sealing plate. The second guide plate is fixedly connected to the side wall of the screening box. A support arm is provided on the support platform, and the support arm is fixedly connected to the inner wall of the screening box. The third motor is fixed at the bottom of the support platform. A protective cover is provided on the outside of the third motor for isolation and protection. The output shaft of the third motor passes through the support platform. The screening plate is located on the support platform. The rotating shaft adopts a spline structure to insert the output shaft of the third motor.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] This solution includes a mixing mechanism that can thoroughly mix the red mud fines and added ingredients through a mixing component. During this process, the second motor in the mixing component drives the main shaft and the second sealing plate to rotate. Firstly, the second sealing plate can keep the second channel closed during rotation to prevent material leakage. Secondly, the second sealing plate can also drive the stirring shaft to rotate around the main shaft. During the large-scale mixing process of the fan plates, the stirring shaft can also mix the red mud and added ingredients between adjacent fan plates, greatly improving the mixing efficiency. At the same time, the mixing method using fan plates and stirring shaft can turn the material at the bottom to the top, realizing the mixing and replacement of the upper and lower areas. This can prevent the added ingredients from sinking to the bottom due to uneven mixing, thus avoiding uneven mixing. Attached Figure Description

[0029] To facilitate understanding by those skilled in the art, the following is in conjunction with the appendix. Figure 1-9 The technical solution of this utility model will be further described in detail below.

[0030] A red mud treatment grinding, screening and mixing integrated machine includes a crushing mechanism 1, a screening mechanism 2 and a mixing mechanism 3 arranged sequentially from top to bottom; the crushing mechanism 1 is fixedly connected to the screening mechanism 2, and the screening mechanism 2 is fixedly connected to the mixing mechanism 3.

[0031] The mixing mechanism 3 includes a mixing box 31, with first through grooves 311 on both sides of the mixing box 31 and second through grooves 312 on the other two sides of the mixing box 31.

[0032] The mixing chamber 31 has a first slide rail 314 on its inner wall and a second slide rail 315 on its outer wall.

[0036] The crushing mechanism 1 includes a crushing box 11, a first motor 12, a crushing roller 13, and a first guide plate 14. The bottom end of the crushing box 11 is fixedly connected to the screening box 21 by bolts. The crushing roller 13 is rotatably connected to the crushing box 11 by through shafts at both ends. The first guide plate 14 is located above the crushing roller 13 and is fixedly connected to the inner wall of the crushing box 11. The first motor 12 is fixed to the outer wall of the crushing box 11, and the output shaft of the first motor 12 is connected to the through shaft at the end of the crushing roller 13. The upper part of the first guide plate of the crushing box is provided with a cover plate to prevent dust overflow or material splashing during the crushing process. The material to be crushed is fed in by opening the cover plate, and the crushing begins when the cover plate is closed.

[0037] A red mud treatment, grinding, screening, and mixing integrated machine operates as follows:

[0038] Red mud blocks are placed into the crushing box 11 along the first guide plate 14. The first motor 12 drives the crushing roller 13 to crush the red mud blocks. The crushed red mud enters the screening box 21. The third motor 26 drives the arc arm 271 to rotate, which not only improves the screening operation speed and avoids accumulation, but also works with the screening plate 25 to achieve the grinding effect. At the same time, after the crushing and feeding stops, the larger red mud blocks left after screening are opened by the second electric push rod 28 pulling the first sealing plate 22 to open the discharge port 211. Then, the arc characteristic of the arc arm 271 driven by the third motor 26 is used to push the large red mud particles out of the screening box 211 along the discharge port 211. The red mud blocks are transferred through the second guide plate 23, and the transferred large red mud particles are collected in a centralized manner.

[0039] The screened red mud fines enter the mixing box 31, and then other ingredients for mixing are added through the feed inlet 32. The second motor 38 drives the main shaft 33 to rotate, which in turn drives the second sealing plate 35 to rotate. The second sealing plate 35 drives the stirring shaft 34 to rotate around the main shaft 33. Furthermore, since the gear at the end of the stirring shaft 34 meshes with the internal gear disk 36, the stirring shaft 34 can also rotate during the rotation. The stirring assembly can fully mix the ingredients and red mud fines, avoiding the disadvantage of uneven mixing caused by the ingredients settling quickly at the bottom of the mixing box 31 after being added. After mixing is completed, the electric push rod 317 pushes the tray 313 to slide open the seal on the bottom of the mixing box 31, allowing the mixture to be discharged naturally.

[0040] It is important to note that the mixing box is designed to be open at both ends, and the material is sealed and opened for storage using a tray and a diversion block.
