[0029] It should be noted that in this embodiment, the sorting baffle 27 can be rotated relative to the casing 21 to facilitate adjustment of the inclination angle of the sorting baffle 27. After the inclination angle of the sorting baffle 27 is adjusted, it can be connected and fixed relative to the casing 21 by fixing bolts and nuts. In some other embodiments, other connection methods can also be used to limit and fix the sorting baffle 27.

Then the material continues to fall downward, the opening degree of the remaining air adjusting doors 26 below the air duct 25 is adjusted, and the inclination angle of the sorting baffle 27 is adjusted. The air flowing through the wind guide plate 28 separates the stones and mud blocks in the material falling downward, the stones and mud blocks are conveyed out of the sundry discharging port 203, the material from which the stones and mud blocks are removed is conveyed into the pulverizer 3 from the discharging port 202, the operation of removing the stones and mud blocks from the material utilizes the principle of specific gravity, which is not described here. The material is conveyed into the pulse bag dust collector 5 through the conveying pipeline 4 after being pulverized by the pulverizer 3. The material and the gas are separated by the pulse bag dust collector 5 under the action of the air blower 6. The gas is discharged through the air outlet of the air blower 6, and the material is conveyed into the quantitative discharging assembly 7. The material discharged quantitatively by the quantitative discharging assembly 7 is conveyed into the next process.

[0034] Preferably, the magnetic separation assembly 24 comprises a rotating plate 241 rotatably connected to the casing 21, electromagnets 242 arranged on the inner side wall of the rotating plate 241, a dripping plate 243 arranged on the casing 21 above the inner side wall of the rotating plate 241, a storage bag 247 detachably connected to the bottom of the rotating plate 241 and the dripping plate 243, a fixing seat 246 arranged on the movable end of the rotating plate 241, a fixing hook 245 rotatably connected to the casing 21 and used for clamping the fixing seat 246, and an extension link 244 arranged between the rotating plate 241 and the dripping plate 243, with the two ends of the extension link 244 rotatably connected to the rotating plate 241 and the dripping plate 243 respectively, as shown in Figures 3-4 Fig. 2. In daily use, the rotating plate 241 remains in the state as shown in Figure 3 Fig. 2, and the materials slide down along the dripping plate 243, at this time, the electromagnets 242 are connected to the power supply, and thus the magnetic metals such as iron particles, iron wires and iron-containing metal blocks in the materials are attracted. When it is needed to clean the magnetic metals on the electromagnets 242, the fixing hook 245 is removed from the fixing seat 246, i.e. the fixing relationship between the movable end of the rotating plate 241 and the casing 21 is released, then the rotating plate 241 is rotated relative to the casing 21 to be opened, at this time, the storage bag 247 arranged at the bottom of the rotating plate 241 and the dripping plate 243 is stretched, then the power supply of the electromagnets 242 is disconnected, and the magnetic metals on the electromagnets 242 fall down along the electromagnets 242 to the inside of the storage bag 247 under the action of no magnetic force, then the storage bag 247 is detached and poured out, it is needed to be explained that in the embodiment, the storage bag 247 is connected to the rotating plate 241 or the dripping plate 243 through connecting bolts, so as to facilitate the detachment and installation.

[0035] Preferably, the quantitative discharging assembly 7 comprises a barrel 71 arranged on the solid discharging pipeline of the pulse cloth bag dust collector 5, a connecting shaft 72 arranged inside the barrel 71 and rotationally connected with the barrel 71, a plurality of partition plates 73 arranged radially on the outer wall of the connecting shaft 72, a plurality of rollers 74 rotationally connected with the movable end of the partition plates 73 and used for assisting the rotation of the partition plates 73 relative to the inner wall of the barrel 71, a motor 79 connected with the connecting shaft 72 and used for driving the rotation of the connecting shaft 72, and cavities for storing materials are formed between adjacent two partition plates 73. The connecting shaft 72 is perpendicular to the solid discharging pipeline of the pulse cloth bag dust collector 5. When the motor 79 drives the rotation of the connecting shaft 72 and the partition plates 73, each cavity for storing materials receives the materials conveyed from above, and the materials are discharged from the cavity when the cavity rotates downward. The above process is repeated to quantitatively convey the materials. Generally, in order to improve the accuracy of the quantitative conveying of the materials, the movable end of the partition plate 73 is close to the inner wall of the barrel 71. In order to facilitate the smooth rotation of the barrel 71, the roller 74 is arranged to rotationally connect with the movable end of the partition plate 73. The outer wall of the roller 74 is in contact with the inner wall of the barrel 71, thereby assisting the smooth rotation of the partition plate 73.

[0036] Further, the cavity is slidably connected with a blocking block 75 used for adjusting the volume of the cavity. One side of the barrel 71 is rotationally connected with a mounting plate 77. The blocking block 75 is provided with a movable handle 76 used for sequentially penetrating the barrel 71 and the mounting plate 77. The mounting plate 77 is rotationally connected with a positioning plate 78. The positioning plate 78 is connected and fixed with the movable handle 76 through bolts. The blocking block 75 extends into the cavity for storing materials, and can block the space inside the cavity, thereby reducing the volume of the cavity for storing materials. In this way, the discharging amount can be adjusted according to different discharging requirements. After the position of the blocking block 75 is adjusted, the positioning plate 78 is rotated to be attached to the surface of the movable handle 76. Then, the positioning plate 78 and the movable handle 76 are connected and fixed through bolts, thereby connecting the movable handle 76 and the mounting plate 77. The movable handle 76 can also rotate with the mounting plate 77 relative to the barrel 71. When the motor 79 drives the rotation of the connecting shaft 72 and the partition plates 73, the blocking block 75 and the movable handle 76 rotate with the connecting shaft 72 relative to the barrel 71.

[0037] Preferably, the movable handle 76 is provided with a scale. After the staff releases the fixing relationship between the positioning plate 78 and the movable handle 76, the movable handle 76 is pushed into the barrel 71. The distance that the blocking block 75 is pushed into the barrel 71 can be known from the scale, thereby calculating the volume change of each cavity for storing materials, so as to accurately adjust the size of the cavity for storing materials, and further accurately adjust the material amount of each discharging.

[0038] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
