Technical Field
[0001] This patent application belongs to the technical field of mining equipment, and more specifically, relates to an automatic separation and screening device for magnetite cemented filling bulk. Background Art
[0002] With the development of mining technology, more and more mines use tailings cementation filling method to recover ore bodies. After the tailings are rushed into the underground mining area, they will mix with the loose covering layer in the mining area. If the flow relationship between the two is not clear, it will lead to excessive depletion of the filling body fragments, and in severe cases, it will pose a threat of sand and gravel flow in the underground mining area.
[0003] At present, the screening devices used in mines with backfill mining are mainly assembled from wooden columns, wooden cross braces and acrylic board baffles. During use, they are affected by the flow impact of the backfill and the covering layer bulk, resulting in poor stability of the screening devices, a short service life, and the devices are easily damaged and corroded. They cannot be recycled for a long time, which increases production costs and consumes resources to a certain extent. At the same time, the screening devices currently used in mines with backfill mining mainly use manual screening to screen magnetite and backfill bulk, which requires a lot of manpower and is labor-intensive, and is not conducive to the safety of operators.

[0009] Furthermore, the ore discharge port includes a base plate and a plurality of outlets spaced apart at the bottom of the base plate. The base plate is vertically inserted between the upright column and the waist cross brace, and the outlets of the base plate are arranged downward.
[0010] Furthermore, the substrate is made of acrylic board.
[0011] Furthermore, the outlet is located at 1 / 2 to 2 / 3 of the height of the substrate.

[0013] Furthermore, the front and rear baffles and the left and right baffles are all tempered glass baffles, and the bottom edges of the front and rear baffles and the left and right baffles extend to the top surface of the waist cross brace and the bottom stainless steel plate.

The front and rear baffles 3 and the left and right baffles 10 are respectively inserted in the front and rear and on the left and right sides of the columns 5. The discharge port 4 is vertically inserted on the columns 5 and the waist cross braces 11, and is tightly fitted with the front baffle 3. The bulk filling body is discharged through the discharge port 4 and flows into the screening device 2 at the front end. The overall structure is stable and reliable. The bottom stainless steel plate 13 is inserted flatly into the waist cross brace 11 and the inner side of the column 5. Specifically, the bottom stainless steel plate 13 is located below the ore discharge port 4 and above the screening device 2, it is located on the inner side of the column 5, and its outer edge exceeds the ore discharge port 4 by 3 to 5 cm. The bottom stainless steel plate 13 is used to receive the discharged bulk filling material without affecting the discharge of the bulk material discharged from the ore discharge port 4.
[0026] like Figure 2The screening device 2 is installed at the lower part of the waist cross brace 11. The screening device 2 includes a receiving chute 6 fixed to the outside of the column 5 below the waist cross brace 11, a permanent magnetic wheel 7 below the receiving chute 6, a scraper 14 cooperating with the permanent magnetic wheel 7, a magnetite chute 12 corresponding to the receiving chute 6, and a bulk filling screen 8. The lower end surface of the receiving chute 6 is connected to the permanent magnetic wheel 7.

The receiving chute 6, permanent magnetic wheel 7, magnetite chute 12, and bulk filler screen 8 are all fixed to both sides of the column 5 below the waist cross brace 11. The receiving chute 6 and magnetite chute 12 are located on the same side of the column 5, while the bulk filler screen 8 is located on the other side of the column 5.
[0028] In structural design, such as Figure 3 The ore-drawing port 4 includes a base plate and multiple outlets spaced apart at the bottom of the base plate. The base plate is vertically inserted between the upright column 5 and the waist cross brace 11, and the outlets of the base plate are set downward.

The various components are connected by welding to further ensure the stability and reliability of the structure.
[0032] When the device is in use, the bulk filler is discharged through the ore discharge port 4 and flows into the screening device 2 at the front end through the bottom stainless steel plate 13. The bulk filler flowing into the screening device 2 first enters the ore receiving chute 6, and is automatically adsorbed by the permanent magnetic wheel 7 to separate the bulk filler from the magnetite. The separated bulk filler falls directly into the bulk filler screen 8 for screening. The magnetite is adsorbed on the permanent magnetic wheel 7 and then scraped by the scraper 14. The screened magnetite enters the magnetite chute 12, thereby realizing automatic screening of the bulk filler and the magnetite.
