Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] For example, see Figure 1-3 A catalyst raw material screening and impurity removal device in this embodiment includes a screening box 1, in which a processing mechanism is provided, and the processing mechanism includes a feed pipe 2 fixedly installed on the rear surface of the screening box 1, a grinding mechanism 3 arranged in the screening box 1, a collecting component 4 arranged outside the screening box 1, a motor 5 fixedly installed on the rear surface of the screening box 1 and a filter plate 6 fixedly installed in the screening box 1.

[0024] The grinding mechanism 3 includes a mounting plate 31 slidably mounted in the screening box 1, a motor 32 fixedly mounted on the lower surface of the mounting plate 31, a grinding roller 33 fixedly mounted on the output end of the motor 32, a grinding seat 34 fixedly mounted in the screening box 1, a discharge plate 35 fixedly mounted in the screening box 1 and a cylinder 36 fixedly mounted on the grinding seat 34.

[0025] In this embodiment, the collecting assembly 4 includes a connecting plate 41 fixedly mounted on the outer peripheral wall of the screening box 1 and a collecting box 42 fixedly mounted on the upper surface of the connecting plate 41. In order to increase the strength of the connecting plate 41, reinforcing ribs are fixedly connected between the connecting plate 41 and the screening box 1.

[0026] In this embodiment, a rotating shaft 7 is rotatably connected inside the screening box 1, and the output end of the second motor 32 is fixedly connected to the rotating shaft 7. In order to increase the effect of the rotating shaft 7 in dispersing the raw materials, a scattering roller is fixedly connected to the upper surface of the rotating shaft 7.

[0027] In this embodiment, in order to allow the rotating shaft 7 to break up the raw materials and allow the raw materials to be evenly distributed on the upper end of the filter plate 6, the rotating shaft 7 is located on the upper side of the filter plate 6, the rotating shaft 7 is located on the lower side of the discharge plate 35, and the discharge plate 35 is located on the upper side of the filter plate 6.

[0028] It should be noted that, in order to increase the amount of material entering the screening box 1 that can be ground, the feed pipe 2 is located at the upper end of the discharge plate 35 , and in order to enable discharge, a discharge chute is provided in the discharge plate 35 .

[0029] In this embodiment, the number of the cylinders 36 is two, and a controller is fixedly connected inside the screening box 1 , and the controller is electrically connected to the cylinders 36 and the motor 5 .

[0030] In this embodiment, the grinding roller 33 and the grinding seat 34 are located in the same plane, and a discharge trough is provided on the inner wall of the screening box 1 .

[0031] Embodiment 2:

[0032] See also Figure 1 In this embodiment, the discharge trough filter plate 6 is inserted into the discharge trough. In order to allow the raw materials on the upper surface of the filter plate 6 to be discharged through the discharge trough, the angle between the left surface of the filter plate 6 and the left surface of the inner cavity of the screening box 1 is an acute angle, and the angle between the right surface of the filter plate 6 and the right surface of the inner cavity of the screening box 1 is an acute angle.

[0033] The working principle of the above embodiment is:

[0034] The user first feeds the raw material into the screening box 1 through the feed pipe 2, and then the user starts the second motor 32 through the controller, and the second motor 32 drives the grinding roller 33 to rotate, so that the grinding roller 33 and the grinding seat 34 grind the raw material together. When the user needs to adjust the coarseness of the raw material after grinding, the user starts the cylinder 36 through the controller, and the cylinder 36 drives the mounting plate 31 to move upward, and the cylinder 31 drives the grinding roller 33 to move upward, thereby adjusting the gap between the grinding roller 33 and the grinding seat 34, and the ground raw material moves downward through the discharge plate 35. Then the user starts the first motor 5 through the controller, and the first motor 5 drives the rotating shaft 7 to rotate. The material moving downward through the discharge plate 35 hits the upper surface of the scattering roller, and then is scattered, and then hits the upper surface of the filter plate 6 for filtration. The raw material dropped by the filter plate enters the collection box 42 by gravity, thereby completing the entire operation process.

[0035] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
