Description

Technical Field

[0001] This utility model relates to the field of red mud treatment technology, and in particular to a Bayer process red mud treatment device. Background Technology

[0002] As a major producer of alumina, China discharges millions of tons of red mud annually. Red mud is an industrial solid waste generated during the alumina extraction process in the aluminum industry and is highly alkaline. The large-scale dumping of red mud not only occupies land and wastes land resources, but also causes environmental problems such as soil alkalization and groundwater pollution due to the alkaline solution seeping into the soil.

[0003] A search revealed a public disclosure (announcement) number: CN220257273U, which discloses a dealkali treatment device based on the Bayer process for red mud. The device includes a dealkali treatment chamber and a filter press mechanism corresponding to the chamber via a corresponding frame. The filter press mechanism includes a filter basket, a compression block matching the filter basket, and an electrically operated telescopic rod. The electric telescopic rod drives the filter basket to rise and fall, achieving its engagement with the compression block for filter pressing and its movement within the dealkali treatment chamber. This device compresses the filter cake, thereby squeezing the alkali solution into the dealkali treatment chamber, minimizing the alkali content in the filter cake. Its overall structure is simple, easy to operate, and highly practical.

[0004] In the aforementioned existing technical solutions, a fixed filter plate structure is used, which makes it impossible to disassemble and clean the filter plate separately. This causes red mud particles to easily accumulate in the deep layers of the filter pores and gradually harden. Conventional rinsing is insufficient to completely remove the stubborn deposits embedded in the pores. This non-removable structure makes the filter plate maintenance incomplete, ultimately shortening the equipment maintenance cycle and reducing the overall service life.

[0005] Therefore, we propose a Bayer process red mud treatment equipment. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide a Bayer process red mud treatment equipment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a Bayer process red mud treatment device, comprising a treatment box, a mounting frame, and a filter frame. The filter frame and the treatment box have positioning holes two and one respectively on their side walls. Fixing rods are fixed on both sides of the treatment box, and fixing blocks are fixed on the top of the fixing rods. A sliding rod is slidably connected to the center of each fixing block. A pull plate and an insert block are fixed at both ends of the sliding rods respectively. An insert rod is fixed at one end of each insert block, and a spring is fixed on each insert block. Two limiting holes one are opened on the sliding rod, and a limiting hole two is opened on the top of the fixing block. A limiting rod is inserted into the limiting hole two, and a spring two is sleeved on the limiting rod.

[0008] Preferably, an electric telescopic rod is fixedly connected to the center of the top of the mounting frame, a box cover is fixedly connected to the extended end of the electric telescopic rod, and a pressing block is fixedly connected to the bottom of the box cover.

[0009] Preferably, support blocks are fixedly connected to the end points of the four walls of the processing box, and the box cover is slidably connected to the mounting frame.

[0010] Preferably, the insertion rod and positioning hole one and positioning hole two are mutually compatible and both have a cross-shaped structure.

[0011] Preferably, the second spring is sleeved on the top position of the limiting rod at the fixed block, and one end of the second spring is fixedly connected to the top wall of the fixed block.

[0012] Preferably, the insert block is fixed at the end of the slide rod that is close to each other, and the pull plate is fixed at the end of the slide rod that is far from each other.

[0013] This invention provides a Bayer process red mud treatment device. It has the following beneficial effects:

[0014] This Bayer process red mud treatment equipment releases the limit on the slide rod through the cooperation of the limit rod and spring two. Through the cooperation of the insertion block, insertion rod, spring one and insertion hole, the filter frame can be quickly disassembled and installed, making the filter frame maintenance more thorough and thus improving the overall service life of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: A Bayer process red mud treatment equipment, such as Figs. 1-3As shown, the system includes a processing box 1. A U-shaped mounting bracket 101 is fixedly connected to the top of the processing box 1. An electric telescopic rod 201 is fixedly connected to the center of the top of the mounting bracket 101. A box cover 2 is fixedly connected to the extended end of the electric telescopic rod 201. The box cover 2 is slidably connected to the mounting bracket 101. A pressing block 202 is fixedly connected to the bottom of the box cover 2. Support blocks 302 are fixedly connected to the ends of the four walls of the inner cavity of the processing box 1. Filter frames 3 are placed on the four support blocks 302. The filter frames 3 and the pressing blocks 202 are mutually compatible. Positioning holes 2 301 are opened at the center of the two side walls of the filter frames 3. Positioning holes 1 102 are opened at the positions corresponding to the positioning holes 2 301 on the two side walls of the processing box 1. Fixing rods 6 are fixedly connected to the center of the two side walls of the processing box 1. Fixing blocks 402 are fixedly connected to the top of the two fixing rods 6. The center of each slide rod is slidably connected to a slide rod 4. The ends of the two slide rods 4 that are far apart from each other are fixedly connected to a pull plate 401. The ends of the two slide rods 4 that are close to each other are fixedly connected to an insert block 404. The ends of the insert blocks 404 that are close to each other are fixedly connected to an insert rod 405. The insert rod 405 and the positioning hole 102 and the positioning hole 201 are mutually compatible and are all cross-shaped structures. The insert block 404 is located on both sides of the slide rod 4 and the spring 103 is fixedly connected to the wall of the fixing block 402. The slide rod 4 has two limiting holes 1502. The top of the fixing block 402 has a limiting hole 2503 that is compatible with the limiting hole 1502. The inner cavity of the limiting hole 2503 is inserted into a limiting rod 5. The limiting rod 5 is fitted with a spring 2501. One end of the spring 2501 is fixedly connected to the top wall of the fixing block 402.

[0024] The working principle of this utility model:

[0025] When the filter frame 3 needs to be replaced or cleaned during use, the limiting rod 5 is lifted upwards. At this time, the pull plate 401 is pulled, which in turn moves the insertion block 404 at one end of the slide rod 4 away from the processing box 1. As a result, the insertion rod 405 on the insertion block 404 is released from the inner cavity of the positioning hole 2 301. When the limiting hole 1 502 on the slide rod 4 near the insertion block 404 is aligned with the limiting hole 2 503, the limiting rod 5 is released. Under the elastic force of the spring 2 501, the insertion end of the limiting rod 5 is inserted into the limiting hole 1 502 to limit the position of the insertion rod 405.
