Description

Technical Field

[0001] This utility model relates to the field of red mud technology, specifically a red mud settling and feeding device. Background Technology

[0002] A settling tank is a gravity sedimentation device used for solid-liquid separation, also known as a thickener or clarifier. It is used to increase the concentration of a suspension and simultaneously obtain a clarified liquid. Settling tanks are commonly used in the separation and settling of red mud in alumina production. After leaching, the slurry enters a dilution tank and is mixed with the washing liquid from the primary settling and washing tank to produce a diluted slurry. The diluted slurry is then sent to the separation settling tank for sedimentation and separation. The underflow after sedimentation and separation undergoes 4-5 reverse washing cycles to remove useful components from the red mud. The red mud is then filtered and stored.

[0003] In actual production, the solid content of the feed to the settling tank has a significant impact on the settling tank's capacity and operational stability. The higher the solid content of the feed, the worse the red mud's settling effect in the settling tank. Therefore, reducing the solid content of the feed to the settling tank is of great significance for the stable operation of red mud separation and washing in alumina production.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a red mud settling and feeding device, which has the following beneficial effects: This invention has the advantage of diluting red mud and improving the settling effect. The operator installs the feed pipe in the designated position, and then turns on the motor on the mounting frame. At this time, the motor drives the first pipe to rotate, which in turn drives the second pipe to rotate simultaneously, causing the second pipe to break up the solids. Through the water delivery mechanism, water below the baffle is drawn into the first pipe and then sprayed out through the second pipe to dilute the red mud. This reduces the solid content of the red mud and improves its settling effect, solving the problem that the higher the solid content of the red mud in the settling tank, the worse the settling effect.

[0014] 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.

[0015] Example 1 See Figure 1-4A red mud settling and feeding device, characterized in that it includes a feed pipe 1; a dilution assembly 2 is provided on the feed pipe 1, the dilution assembly 2 including: a water tank 21, fixedly connected to the outer wall of the feed pipe 1; a mounting frame 22, fixedly connected to the top of the water tank 21; a motor 23, fixedly connected to the top of the mounting frame 22; a first pipe body 24, fixedly connected to the output end of the motor 23, and penetrating the feed pipe 1 and inserted into the interior of the water tank 21; and a second pipe body 25, inserted into the first pipe body. The outer wall of the pipe body 24; the partition 26, fixedly connected to the inner wall of the water tank 21; the water delivery mechanism 27, disposed on the feed pipe 1; the water delivery mechanism 27 includes: a water pump 271, fixedly connected to the top of the partition 26, and the pipe body 24 rotatably connected to the outlet end of the water pump 271; the inlet pipe 272, fixedly connected to the inlet end of the water pump 271; a sealing sleeve 6 is rotatably connected to the outer wall of the pipe body 24, and the sealing sleeve 6 is fixedly connected to the outer wall of the feed pipe 1.

[0016] When ready for use, the operator installs the feed pipe 1 in the designated position, and then turns on the motor 23 on the mounting frame 22. At this time, the motor 23 drives the first pipe body 24 to rotate, which in turn drives the second pipe body 25 to rotate simultaneously. This causes the second pipe body 25 to break up the solids, and water is pumped into the first pipe body 24 through the water delivery mechanism 27, and then sprayed out through the second pipe body 25 to dilute the red mud, thereby reducing the solid content of the red mud and improving its sedimentation effect. The operator turns on the water pump 271, which pumps water into the first pipe body 24 through the water inlet pipe 272. The operation is simple and improves the convenience of the device. When the first pipe body 24 rotates, the sealing sleeve 6 seals the gap between the first pipe body 24 and the feed pipe 1 to prevent liquid from flowing out and contaminating the outside, thereby improving the safety of the device.

[0017] Example 2 See Figure 1-4 Based on Embodiment 1, auxiliary functions have been added; Multiple tube bodies 25 are provided; a filter plate 4 is fixedly connected to one end of each tube body 25; and a one-way valve 5 is provided on each tube body 25.

[0018] During use, the rotation of tube 24 drives multiple tubes 25 to rotate simultaneously, which improves the device's ability to disperse solids and dilutes the red mud more evenly, thus enhancing the device's practicality. The filter plate 4 prevents solids from entering tubes 25 and clogging them, thus improving the device's stability. The one-way valve 5 on tubes 25 prevents liquid from flowing back into tube 24 after dilution, thus improving the device's safety.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
