Description

Technical Field

[0001] The utility model belongs to the technical field of red mud environmental protection treatment, in particular to a filter block breaking device. Background Art

[0002] When alumina is produced industrially, the discharged industrial solid waste is called red mud because it contains a large amount of iron oxide and looks similar to red soil. About 1.0 to 1.8 tons of red mud are discharged for every ton of alumina produced, and it is usually piled in rainproof land.

[0003] The accumulation of red mud will affect the normal use of land. The recycling and utilization of red mud can be roughly divided into dry treatment and wet treatment. In the dry treatment process, the red mud first needs to be filtered, dried, crushed, mixed with additives, and finally roasted, ground, magnetically separated, and other processes are carried out to extract high-grade metals.

[0004] Among them, red mud first contains water, which needs to be removed. At this time, a filter press is needed to operate. After the filter press filters the red mud, the filter material is in the form of flat blocks, which still contain more than 20% water. Therefore, the filter blocks need to be broken up, dehydrated, and then crushed. Since the water-containing filter blocks have a certain viscosity, they are easy to stick to the machine when they are broken up and dehydrated, causing material blockage. Therefore, the existing breaking structure needs to be improved to improve efficiency. At the same time, the crushing process of the filter blocks after drying needs to be strengthened to improve the processing degree of the filter blocks and facilitate subsequent fine crushing operations.

[0029] In this utility model:

[0030] Reference Figure 1-7 :

[0033] The scattering assembly includes: a guide rail 103, a feeding slide 2, a telescopic cylinder 201, an opening groove 202, a circular cutter 3, a rotating tool holder 4, and a blade 401.

A blade 401 is integrated between the rotating blade holder 4. The annular cutter 3 rotates under the action of the motor to cut the flaky red mud material into strips. As the strips of red mud slide downward and come into contact with the rotating blade holder 4, the blade 401 cuts the strips of red mud into dices. At this time, the dices of red mud are smaller in size, which can improve efficiency during drying.

[0044] Working principle: First, the flaky red mud material that has been filtered is introduced from the feed port 101 and falls on the feeding slide 2. At this time, the feeding slide 2 is shaken obliquely under the telescopic action of the telescopic cylinder 201. With the anti-stick coating, the flaky red mud material slides down under gravity. At this time, the annular cutter 3 rotates under the action of the motor to cut the flaky red mud material into strips. As the strips of red mud material slide downward, they come into contact with the rotating tool holder 4. The blade 401 cuts the strips of red mud material into dices. At this time, the dices of red mud material are smaller in size, which can improve efficiency during drying. The dices of red mud material fall into the shaking plate 6, which is vibrated by the vibration motor 601. Moving slowly, the electric heating plate 602 uses heat conduction to dry the diced red mud material. The guide block 603 is not set in a standard manner, which can disturb the diced red mud material and improve the drying efficiency. Then, the dried diced red mud material enters the crusher 7, is crushed by the crushing roller 701, and the crushed material enters the screening chamber 8 along the chain conveyor belt 801. The sieve plate 803 at the bottom of the screening chamber 8 screens the crushed material. Qualified material is sent away along the feeding conveyor belt 9, and unqualified material is moved to the screw feeder 5 under the action of the steel brush 802. The screw feeder 5 lifts the material to the shaking plate 6, and the drying and crushing operations are carried out again, thereby improving the fine processing of the material.
