TECHNICAL FIELD

[0001] The utility model relates to the coal mine washing technology field, concretely is a coal mine mineral washing processing equipment. BACKGROUND

[0002] The coal produced by coal mine contains a certain amount of coal block, coal gangue and other minerals, in order to improve the quality of coal and extract other minerals, it needs to use washing processing equipment to wash and process after mining coal, so as to obtain higher quality coal mine.

[0003] In the prior art, because the density of coal block and coal gangue is different, usually coal mine is put into coal washing equipment, high-quality coal block and coal gangue are separated through the vibration of coal washing equipment, coal block floats on water, and coal gangue sinks under water.

[0004] But this coal washing mode can cause the coal mine pressed and unable to float in the coal gangue sinking under water, and further cause the coal washing efficiency to reduce.

[0005] Therefore, a coal mine mineral washing processing equipment is provided. SUMMARY

[0006] The utility model discloses a kind of coal mine mineral washing processing equipment, to solve the problem raised in the above background art.

[0007] To achieve the above object, the utility model provides the following technical scheme: a kind of coal mine mineral washing processing equipment, including shell, the inside two sides of the shell are symmetrically installed with fixed shell, the bottom of the fixed shell is installed with straight board, one side of the straight board is installed with arc plate, the bottom of the fixed shell is rotatably connected with transmission shaft, the outer side of the transmission shaft is evenly installed with blade.

[0009] Preferably, a drive sprocket is installed on the output shaft of the drive motor.

[0010] Preferably, the end of the transmission shaft penetrates the fixed shell and is installed with a driven sprocket, and the driven sprocket and the drive sprocket are connected by a chain drive.

[0011] Preferably, the end surface of the blade and the surface of the arc plate are mutually attached.

[0012] Preferably, a gangue discharging hole is formed in one side of the shell.

[0013] Preferably, an included angle is provided between the inner bottom wall of the shell and the straight board.

[0014] Compared with the prior art, the coal gangue is stirred by the blades, so that the coal blocks in the coal gangue can be stirred and floated, the coal blocks are prevented from being pressed and floated, the situation that the coal blocks are discharged with the coal gangue is avoided, and the efficiency of coal mine washing and selecting is improved.

[0019] The technical scheme in the utility model embodiment will be clearly and completely described below with reference to the drawings in the utility model embodiment.

[0020] Please refer to Figures 1-3 The utility model provides a kind of technical scheme: a coal mine mineral washing and selecting processing equipment, including shell 1, the inside two sides of shell 1 are symmetrically equipped with fixed shell 5, the bottom of fixed shell 5 is equipped with straight plate 6, one side of straight plate 6 is equipped with arc plate 7, the bottom of fixed shell 5 is rotatably connected with transmission shaft 8, and the outer side of transmission shaft 8 is evenly equipped with blade 9.

[0021] As Figure 1 Shown: the outer side of shell 1 is equipped with support plate 3, and driving motor 4 is installed on support plate 3;Through the above setting, driving motor 4 can more conveniently drive transmission shaft 8 to rotate, so that blade 9 stirs the coal mine at the bottom.

[0022] As Figure 1 And Figure 3 Shown: the output shaft of driving motor 4 is equipped with driving sprocket 11, the end of transmission shaft 8 penetrates fixed shell 5 and is equipped with driven sprocket 10, and driven sprocket 10 and driving sprocket 11 are connected by chain transmission;Through the above setting, driving motor 4 drives driving sprocket 11 to rotate, then drives driven sprocket 10 to rotate by chain, so that transmission shaft 8 can drive blade 9 to rotate.

[0023] As Figure 2 And Figure 3As shown: the end outer surface of the blade 9 and the surface of the arc plate 7 are mutually attached; through the above setting, the blade 9 can more efficiently and quickly agitate the coal mine, avoiding the situation that the coal mine slips away from the gap between the blade 9 and the arc plate 7.

[0024] As shown: Figure 1 As shown: the side of the shell 1 is provided with a gangue discharge hole 2; through the above setting, another shell is connected on the gangue discharge hole 2, and a conveying belt or a lifting device is arranged inside the shell, so that the coal gangue is transported to other places, facilitating subsequent work, and the washed coal blocks can be transported away from the top of the shell 1.

[0025] As shown: Figure 2 As shown: an included angle is arranged between the inner bottom wall of the shell 1 and the straight plate 6; through the above setting, the included angle can make the blade 9 and the bottom of the shell 1 have a larger space, avoiding the situation that the blade 9 agitates the rear coal mine, thereby affecting the coal washing effect.

[0026] Working principle: first, the coal mine is discharged into the inside of the shell 1 through the conveying belt, and the shell 1 can vibrate under the assistance of external equipment, so that the coal mine moves at the bottom of the shell 1 through the water flow and the vibration of the shell 1, and at the same time, in the process of shaking of the shell 1, part of the coal blocks will float on the water due to the different densities of the coal blocks and the coal gangue, and the coal gangue will sink at the bottom of the shell 1, but some coal mines will be pressed by more coal gangue and cannot float upwards.

[0027] At this time, when the coal gangue moves to the place of the straight plate 6 and the arc plate 7 with the coal mine, it will be driven by the rotating blade 9, so as to agitate the coal gangue, so that the coal blocks in the coal gangue can be stirred out and float on the water for convenient collection work, and then the coal gangue is discharged from the gangue discharge hole 2 into other equipment, which can more conveniently perform subsequent processing steps.

[0028] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
