Technical Field

[0001] The utility model relates to a crushing device, in particular to a crushing device for nickel pig iron production. Background Art

[0002] Nickel pig iron is an alloy mainly composed of nickel and iron, usually made from laterite nickel ore through pyrometallurgy. The specific process includes ore batching, rotary kiln drying and roasting, electric furnace smelting of crude nickel iron, L furnace refining or mechanical stirring desulfurization, and finally obtaining qualified nickel iron particles through water quenching. During the ore batching process, since hard materials may exist in the laterite nickel ore raw materials, it is necessary to crush them first and then proceed to the subsequent process steps. In the current processing technology, the crushing device cannot achieve the functions of crushing and screening at the same time during use. In addition, during the screening process, since the laterite nickel ore has finer crushed soil after being crushed, it is very easy to clog the screen, and the device equipped with a crusher is difficult to clear the screen by vibration. Therefore, it is necessary to develop a nickel pig iron crushing device with the functions of crushing, screening and easy cleaning. Utility Model Content

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1 and Figure 2 As shown in FIG, a schematic diagram of the structure of the present invention is provided. The crushing device for nickel pig iron production of the present invention is provided with a base 10, a support frame 20, a body 30, a feed port 40 and a discharge port 50. The feed port 40 is located above the body 30, and the discharge port 50 is located below the body 30. The feed port 40 and the discharge port 50 are communicated with the body 30. The base 10 is placed on a horizontal plane, and the lower end of the support frame 20 is fixed to the upper end surface of the base 10. Figure 3 As shown, a crusher 31 and a screening plate 32 are provided in the body 30. The screening plate 32 is located below the crusher 31 and is movably mounted on the two side walls of the body 30 in an inclined manner. In addition, the body 30 is placed in the support frame 20. The support frame 20 is provided with a support column 22 and an annular clamp 23. The support column 22 and the annular clamp 23 are integrally formed. Two strip clamps 37 are laterally provided on the two outer side surfaces of the body 30. The strip clamps 37 match the annular clamps 23. The coordinated installation and use of the strip clamps 37 and the annular clamps 23 can improve the stability of the body 30, especially during the operation of the crusher 30, thereby improving the overall stability of the device, preventing the device from malfunctioning due to large-scale vibration, and improving the crushing efficiency of the crushing device.

[0028] In other embodiments, a plurality of mounting plates 21 are provided on the support frame 20, specifically, mounting plates 21 are provided on the front and rear sides of the support frame 20. In this embodiment, the number of mounting plates 21 is 8 in total, and the 8 mounting plates 21 are evenly distributed up and down on the annular clamp 23 of the support frame 20. Bolts are provided on the mounting plates 21, and the main body 30 is fixed in the support frame 20 by bolts, thereby further improving the stability of the main body 30.

[0029] Please refer to Figure 4 and Figure 6 As shown, the sieve plate 32 of the present invention is movably mounted on the side wall inside the main body 30 in an inclined state, and the sieve plate 32 is provided with a first side surface 321, a second side surface 322, a third side surface 323 and a fourth side surface 324, wherein the first side surface 321 is higher than the other side surfaces, the second side surface 322 is lower than the other side surfaces, the third side surface 323 and the fourth side surface 324 are inclined, specifically forming a parallelogram shape, and a discharge hole 33 is provided on the main body 30 at a position where the second side surface 322 of the sieve plate 32 is abutted, and a discharge plate 34 is provided at the outer end of the discharge hole 33.

[0030] During the use of the crushing device of the present invention, the laterite ore raw material is put into the main body 30 from the feed port 40, and the ore is first crushed by the crusher 31. The crushed ore enters the screening plate 32, and the screening plate 32 screens the crushed ore. The qualified ore passes through the screening plate 32 and is discharged from the discharge port 50 below it to enter the next processing process. The larger particle size crushed stone screened by the screening plate 32 rolls off the screening plate 32 and is finally discharged from the discharge hole 33 at the second side 322. The discharge plate 34 at the outer end of the discharge hole 33 makes it easier to collect the uncrushed qualified crushed stone in the storage bag.

[0031] Please refer to Figures 3 to 6As shown, the movable mounting method of the sieve plate 32 of the present invention is specifically as follows: a horizontal bar 325 is respectively provided on the third side 323 and the fourth side 324 of the sieve plate 32, and a chute 35 is provided on the inner side wall of the body 30 at the position where the third side 323 and the fourth side 324 are abutted. The horizontal bar 325 is located within the chute 35, and the highest end of the chute 35 is open and the lowest end is closed. Thus, the sieve plate 32 can be movably mounted on the inner side of the body 30 and is arranged in an inclined state with one end higher and the other lower. In addition, a strip groove (not shown in the figure) is provided on the body 30 at the position where the sieve plate 32 abuts the first side 321. The strip groove is longer than the length of the first side 321 and wider than the thickness of the sieve plate 32. In addition, a pull ring 361 is provided on the first side 321 of the sieve plate 32, and the pull ring 361 is located on the outside of the body 30. When the sieve holes in the sieve plate 32 are clogged and affect the screening effect, it is only necessary to pull the pull ring 361 to pull the sieve plate 32 outward from the strip groove, clean it or replace it with a new sieve plate 32. The replacement is simple and easy to use, does not require a highly automated device, and there is no problem of high failure rate.

[0032] In other preferred embodiments, Figure 2 As shown, a flap 36 is provided on the main body 30 near the first side surface 321, and a square hole is provided at a position corresponding to the flap 36 on the main body 30. The flap 36 cooperates with the square hole, and the upper end surface of the flap 36 is axially connected to the upper end of the square hole, i.e., the main body 30. The flap 36 can realize the function of flipping outward to open, and a pull ring 361 is provided at the lower edge of the flap 36. The length of the flap 36 is greater than the width of the sieve plate 32. After pulling the pull ring 361, the flap 36 can be opened, and the sieve plate 32 in the main body 30 can be taken out and then replaced or cleaned. Similarly, the crushing device of this embodiment also has the effect of being able to be dredged at any time, simple to operate, and easy to replace.

[0033] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
