Description

Technical Field

[0001] This utility model belongs to the field of solid-liquid separation technology in the mineral processing industry, and specifically relates to a combined tank structure of wear-resistant ceramic plates for a dry separator. Background Technology

[0002] Dry magnetic separators are one of the main equipment in mineral processing. Their function is to continuously remove iron from fine powder. Conventional dry magnetic separator tanks are made of stainless steel with Q345 steel plates welded to the surface to resist the erosion of mineral particles smaller than 10mm. The material crushed by high-pressure rollers has many sharp edges and corners. After being separated by the magnetic separation drum, the tailings fall onto the discharge tank and directly erode the inner surface of the welded Q345 steel plate. After a long period of erosion, the welded Q345 steel plate is worn through, resulting in material leakage from the tank. Utility Model Content

[0003] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a combined trough structure of wear-resistant ceramic plates for a dry separator. This invention protects the trough from direct material erosion, improving its protection and extending its service life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] This utility model provides a dry separator grid wear-resistant ceramic plate combined tank structure, including an upper tank and a concentrate sluice and a tailings sluice connected to the lower part of the upper tank. The concentrate sluice and the tailings sluice are both surrounded by multiple obliquely arranged tank lower plates and have a discharge port at the bottom. The characteristic is that the inner sidewall of each tank lower plate is provided with multiple horizontal grid plates and multiple vertical grid plates. The horizontal grid plates and vertical grid plates together form multiple grids. Each grid is provided with a wear-resistant protective structure on the surface of the tank lower plate.

[0006] Furthermore, the wear-resistant protective structure is composed of multiple wear-resistant ceramic sheets, which are arranged with gaps between them in the corresponding grid and are adhered to the surface of the lower plate of the tank body with adhesive.

[0007] Furthermore, a buffer pad is provided on the lower plate of the tank, and the buffer pad is bonded to each of the wear-resistant ceramic sheets and the lower plate of the tank by adhesive.

[0008] Furthermore, both the horizontal and vertical grid plates are higher than the height of the bonded wear-resistant ceramic sheet, thus creating a concave structure within the grid.

[0009] Furthermore, except for the grid at the intersection of adjacent lower plates of the tank, all other grids are square grids. The wear-resistant ceramic pieces at the intersection of adjacent lower plates of the tank are cut according to the corresponding grid shape, and the other wear-resistant ceramic pieces are all squares of the same size.

[0010] Furthermore, each square has the same grid size, and each square has NxN square wear-resistant ceramic sheets of the same size within its grid.

[0011] Furthermore, both the concentrate sluice and the tailings sluice are equipped with reinforcing plates.

[0012] The beneficial effects of this utility model.

[0013] This invention protects the tank body through a wear-resistant protective structure, enabling long-term stable operation of the dry magnetic separator during maintenance cycles. The grid formed also retains some material, protecting the sides and surface of each wear-resistant ceramic sheet. Combined with the wear resistance of the ceramic sheets, this better protects the tank body from direct material erosion, thereby extending the service life of the tank body and improving the productivity of the dry magnetic separator.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

Detailed Implementation

[0020] As shown in the accompanying drawings, this embodiment provides a dry separator with a combined trough structure of grid 8 and wear-resistant ceramic plates 9, including an upper trough 1 and a concentrate sluice 2 and a tailings sluice 3 connected to the lower part of the upper trough 1. Both the concentrate sluice 2 and the tailings sluice 3 are surrounded by multiple obliquely arranged lower trough plates 4 and have discharge ports 5 at the bottom. Reinforcing plates 11 are provided inside both the concentrate sluice 2 and the tailings sluice 3 to enhance their strength.

[0021] The inner sidewalls of the lower plate 4 of the tank are provided with multiple horizontal grids 6 and multiple vertical grids 7. The horizontal grids 6 and vertical grids 7 together form multiple grids 8. Except for the grids 8 at the intersection of adjacent lower plates 4, the other grids 8 are all square grids 8, and each square grid 8 is the same size.

[0022] Each grid 8 has a wear-resistant protective structure on the surface of the lower plate 4 of the tank, which protects the bottom plate of the tank. The horizontal grid plate 6 and the vertical grid plate 7 are both higher than the height of the bonded wear-resistant ceramic sheet 9, thus making the grid 8 have a concave structure.

[0023] The wear-resistant protective structure consists of multiple wear-resistant ceramic sheets 9. The wear-resistant ceramic sheets 9 are arranged in the corresponding grids 8 with gaps between them and are glued to the surface of the lower plate 4 of the tank. Some material can be retained in the gaps between the wear-resistant ceramic sheets 9, and a material pad layer is also formed on the upper part of the wear-resistant ceramic sheets 9 in the concave grids 8.

[0024] The wear-resistant ceramic pieces 9 at the intersection of adjacent lower plates 4 of the tank are cut according to the shape of the corresponding grid 8. The other wear-resistant ceramic pieces 9 are all squares of the same size. Each square grid 8 contains NxN square wear-resistant ceramic pieces 9 of the same size.

[0025] Except for the grids 8 and wear-resistant ceramic plates 9 with special shapes at the intersections that require separate spare parts, when another square unit grid 8 (most of which are square grids 8 and square wear-resistant ceramic plates 9) is damaged, the square wear-resistant ceramic plates 9 are replaced with ones of the same size, which enhances the interchangeability of the wear-resistant ceramic plates 9 and facilitates the replacement of spare parts.

[0026] A buffer pad 10 is also provided on the lower plate 4 of the tank. The buffer pad 10 is bonded to each wear-resistant ceramic sheet 9 and the lower plate 4 of the tank by adhesive, which plays a buffering role when the material impacts the wear-resistant ceramic sheet 9.

[0027] Its working principle is as follows:

[0028] After passing through the dry magnetic separator drum, the material is separated into concentrate and tailings, which fall into the concentrate chute 2 and tailings chute 3 in the tank, respectively. As the material passes through, it washes over the area above the inclined lower plate 4 of the tank. The horizontal grid plate 6 and vertical grid plate 7 are higher than the height of the bonded wear-resistant ceramic sheet 9, making the grid 8 a concave structure. When the material is unloaded, some material remains in the grid 8, forming a material cushion layer on top of and around the wear-resistant ceramic sheet 9. When subsequent material is unloaded, it first impacts the material cushion layer on top of and around the wear-resistant ceramic sheet 9, thus preventing direct contact between the subsequently unloaded material and the lower plate 4 of the tank. This achieves protection of the tank bottom plate using a wear-resistant protective structure, extending the service life of the tank and reducing the frequency of equipment downtime.

[0029] In addition, the buffer pad 10 can play a buffering role. When large particles of material fall onto the wear-resistant ceramic sheet 9, they will impact the wear-resistant ceramic sheet 9. The wear-resistant ceramic sheet 9 is a brittle material, which transmits the impact of the large particles of material to the buffer pad 10. Through the buffering of the buffer pad 10, the impact force of the large particles of material is offset, thereby protecting the wear-resistant ceramic sheet 9, and further protecting the bottom plate of the tank.

[0030] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
