[0028] The present utility model will be further described below with reference to the accompanying drawings:

[0029] As Figures 1-7 shown, an impurity removal device for phosphate production includes support feet 2, a chassis 1 is fixed above the support feet 2, and further includes a quantitative feeding mechanism 3 located at the top of the chassis 1, a discharge port 4 is opened at the bottom of the chassis 1, an impurity removal mechanism 5 is provided inside the chassis 1, and a collection mechanism 6 is provided on one side of the outer wall of the chassis 1.

[0030] In this embodiment: The impurity removal mechanism 5 includes a blower 51 for blowing light impurities from the raw materials. The blower 51 is fixed on the outer wall of the other side of the chassis 1. A ventilation hole corresponding to the blower 51 is provided on the outer wall of one side of the chassis 1. A square hole for the blower 51 to introduce air is provided on the outer wall of the other side of the chassis 1. The diameter of the ventilation hole on the outer wall of one side of the chassis 1 is smaller than the diameter of the impurities. A first rotating shaft 55 is provided inside the chassis 1. A collecting plate 52 for receiving light impurities is rotatably connected to the outside of the first rotating shaft 55. A second rotating shaft 56 is provided below the first rotating shaft 55. A sieve plate 53 for removing larger impurities is rotatably connected to the outside of the second rotating shaft 56. First holes for supporting the first rotating shaft 55 to slide horizontally are provided on the front and rear sides of the chassis 1. Second holes for supporting the second rotating shaft 56 to slide horizontally are provided on the front and rear sides of the chassis 1. Two springs 54 are fixedly connected between the other side of the sieve plate 53 and the inner wall of the chassis 1. Baffles fixed on the inner wall of the chassis 1 are provided on the upper and lower sides of the springs 54. The light impurities are separated from the phosphate by the blower 51 and fall onto the collecting plate 52. The collecting plate 52 can be tilted up and down through the first rotating shaft 55. The sieve plate 53 can be tilted up and down through the second rotating shaft 56. While the sieve plate 53 is tilted up and down through the springs 54, it generates shaking. Through the baffles, all the falling phosphate falls onto the sieve plate 53;

[0031] The collecting mechanism 6 includes a first collecting box 61. The first collecting box 61 is located on one side of the collecting plate 52. A second collecting box 62 is provided below the first collecting box 61. The second collecting box 62 is located on one side of the sieve plate 53. Hinges 66 are used to connect between the collecting plate 52 and the first collecting box 61, and between the sieve plate 53 and the second collecting box 62. Connecting frames 63 are fixed on both sides of the first collecting box 61 and the second collecting box 62. A support plate 64 fixed on the outer wall of the chassis 1 is provided above the connecting frames 63. A cylinder 65 for driving the connecting frames 63 to move up and down is fixedly connected to the support plate 64. The first collecting box 61 and the second collecting box 62 fixed by the connecting frames 63 are pushed to move up and down through the cylinder 65. The collecting plate 52 and the sieve plate 53 are connected by the hinges 66, so that the collecting plate 52 and the sieve plate 53 are forced to continuously tilt and shake around the rotating shaft.

[0032] In this embodiment: The quantitative feeding mechanism 3 includes a feeding box 32. The feeding box 32 communicates with the top of the chassis 1. A feeding shaft 33 is rotatably connected inside the feeding box 32. A quantitative cylinder 31 is fixed around the feeding shaft 33. The quantitative cylinder 31 is provided with evenly distributed grooves. A motor 34 for driving the feeding shaft 33 to rotate is fixed outside the feeding box 32. The phosphate is poured into the feeding box 32. The motor 34 drives the feeding shaft 33 to rotate, thereby driving the quantitative cylinder 31 to rotate, so that the phosphate enters the chassis 1 in batches and quantitatively.

[0033] In this embodiment: The upper half of the chassis 1 is square, and the lower half of the chassis 1 and the discharge port 4 are trapezoidal. Through the trapezoidal lower half of the chassis 1, the phosphate after impurity removal slides down along the inclined inner wall to the discharge port 4 entirely.

[0034] Working principle: Pour the phosphate that needs to be impurity-removed into the feed box 32. Drive the feed shaft 33 to rotate through the motor 34, and then drive the metering cylinder 31 to rotate, so that the phosphate is quantitatively dropped into the interior of the chassis 1. The air blower 51 introduces air to blow onto the falling phosphate, blowing away the light impurities and making them fall onto the collection plate 52. The phosphate continues to fall onto the sieve plate 53. When the air cylinder 65 pushes the connecting frame 63 to move the first collection box 61 and the second collection box 62 downward, the first collection box 61 drives the collection plate 52 to move downward and obliquely through the hinge 66. The collection plate 52 drives the first rotating shaft 55 to slide to one side in the first hole on the chassis 1, so that the light impurities on the collection plate 52 slide down into the first collection box 61. During the process that the second collection box 62 drives the sieve plate 53 to move downward and obliquely through the hinge 66, the sieve plate 53 drives the second rotating shaft 56 to slide to one side in the second hole on the chassis 1. The spring 54 is stressed to make the sieve plate 53 tilt up and down while generating shaking, so that the falling phosphate is dispersed for impurity removal on the sieve plate 53. The larger impurities slide along the sieve plate 53 into the second collection box 62. The phosphate after impurity removal falls along the inner wall of the chassis 1 to the discharge port 4. When the air cylinder 65 pushes the connecting frame 63 to move the first collection box 61 and the second collection box 62 upward, the first collection box 61 drives the collection plate 52 to move upward and reset through the hinge 66. The collection plate 52 drives the first rotating shaft 55 to slide to the other side in the first hole on the chassis 1 to reset. The second collection box 62 drives the sieve plate 53 to move upward and reset through the hinge 66. The sieve plate 53 drives the second rotating shaft 56 to slide to the other side in the second hole on the chassis 1 to reset. Work in such a cycle.

[0035] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
