Description

[0002] With the large-scale mining of the mining industry, the problem of tailings storage has become increasingly serious. Tailings are the waste residue left after the ore is sorted, which contains a variety of mineral components. For example, a large amount of tailings will be produced during the mining process of metal mines. These tailings not only occupy a large amount of land, but may also cause pollution to the soil, water and atmospheric environment. In order to solve the problem of tailings disposal and realize the effective use of resources, people began to explore the comprehensive utilization of tailings. The concept of tailings ceramics came into being. Tailings usually contain a certain amount of basic components required for ceramic production such as silica and alumina. For example, some quartz tailings have a high silica content, while bauxite tailings are rich in alumina. The existence of these components provides a material basis for the production of tailings ceramics. Through appropriate formula adjustment and processing technology, tailings can be converted into ceramic products.

[0033] Example 2:

[0034] On the basis of Example 1, a preferred embodiment of a tailings ceramic filter device provided by the present invention is as follows: Figure 1-6 As shown: the stirring assembly 6 specifically includes: a magnetic generating base 611, fixedly installed at the bottom of the filter tank 3; a magnetic rotating blade 612, arranged at the top of the inner wall of the filter tank 3; a rotating rod 613, arranged on one side of the filter tank 3; a mounting frame 615, fixedly installed on one side of the filter tank 3; and a second motor 616, fixedly installed on the surface of the mounting frame 615.

[0035] The outer wall fixed sleeve of the rotating rod 613 is provided with a passive pulley 614. One end of the rotating rod 613 movably passes through one side of the filter pool 3 and extends to the inside of the filter pool 3 and is rotatably connected to one side of the inner wall of the filter pool 3.

[0036] The output end of motor 2 616 is fixedly installed with rotating shaft 2, and the outer wall fixed sleeve of rotating shaft 2 is provided with a driving pulley 617, and a belt is connected between the driving pulley 617 and the passive pulley 614. The other end of rotating shaft 2 is movable through one side of the filter tank 3 and extends to the interior of the filter tank 3 and is rotatably connected to one side of the inner wall of the filter tank 3. The outer wall of the rotating rod 613 and the outer wall of rotating shaft 2 are respectively fixedly installed with stirring blades 618.

[0037] In this example, the tailings are uniformly stirred by setting a stirring component 6, and the motor 2 616 is started to drive the rotating shaft 2 and the stirring blade 618 to rotate and stir. The rotation of the rotating shaft 2 drives the driving pulley 617 to rotate, and then the passive pulley 614, the rotating rod 613, and the stirring blade 618 are driven by the belt to rotate in conjunction to uniformly stir the upper tailings inside the filter tank 3. The magnetic generating base 611 is started to work, and the electromagnet in the magnetic generating base 611 generates a magnetic field. The magnetic rotating blade 612 will rotate under the action of the magnetic force and uniformly stir the bottom of the filter tank 3, thereby achieving the stirring effect.

[0038] Working principle: First, the operator sets the uniform feeding component 5 to feed uniformly to the left and right. After the tailings enter from the feed hopper 518, the segmented partition 519 can prevent the tailings from gathering and piling up under the action of the vibration motor 517. The vibration motor 517 drives the hollow slide plate 516 to slide up and down on the slide bar 513. The spring 515 can increase the vibration frequency of the hollow slide plate 516. The tailings enter the discharge pipe 5116 from the discharge box 5111, the discharge pipe 1 5112, and the discharge pipe 2 5114. The motor 1 5117 is started to drive the rotating shaft 1 and the spiral blade 5118 to rotate, and the tailings are slowly transported. The electric telescopic rod 51111 is started to drive the discharge pipe 5116 to swing left and right. The discharge pipe 5116 rotates in the connecting sleeve 5113 through the discharge pipe 2 5114 during the swing, so as to avoid the tailings from being too high or too low when entering, thereby affecting the uniformity of filtration. The stirring component 6 is set to stir the tailings evenly, and the second motor 616 is started to drive the second rotating shaft and the stirring blade 618 to rotate and stir. The rotation of the second rotating shaft drives the driving pulley 617 to rotate, and then the passive pulley 614, the rotating rod 613, and the stirring blade 618 are driven by the belt to be linked to stir the upper tailings inside the filter tank 3 evenly. The magnetic generating base 611 is started to work, and the electromagnet in the magnetic generating base 611 generates a magnetic field. The magnetic rotating blade 612 rotates under the action of the magnetic force and stirs the bottom of the filter tank 3 evenly. When the magnetic generating base 611 is energized, the electromagnet in the base generates a magnetic field, and the magnetic field interacts with the magnetism of the magnetic rotating blade 612, causing the magnetic rotating blade 612 to rotate in the filter tank. The rotation of the magnetic rotating blade 612 drives the surrounding tailings to move together, thereby achieving the effect of uniform feeding and stirring.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
