They perform material screening through cylindrical screen surfaces and are suitable for industries such as metallurgy, building materials, and chemicals. They can process dry powdery or granular materials and are particularly suitable for dry production of manufactured sand. They can also be used for screening wet materials. It is an important link in raw coal production, which can greatly improve coal quality and utilization rate and reduce coal transportation costs. To facilitate coal sorting and transportation, larger coal pieces should be crushed. The crushed coal should be of a reasonable size, but sorting is still necessary. This process is quite common in daily life.

[0050] By adopting this preferred solution, after the raw coal that has been screened in the screening rack is collected, it can be transported by means of a transfer mechanism. By moving the transfer rack to one side of the screening rack, the insertion frame is inserted and limited by the insertion block on the surface of the screening rack.

[0053] The high-efficiency cylindrical mineral processing screening system of the present invention will be further described below with reference to the accompanying drawings. Figures 1-3 As shown, the present invention provides a high-efficiency cylindrical mineral processing screening system, including a screening frame 1, a drive motor 2, and a screening mechanism 6.

The upper surface of the transmission frame 3 is rotatably connected to a rotating plate 4. A bearing frame 5 is fixedly connected to the inner wall of the screening frame 1 at the position corresponding to the rotating plate 4. The bearing frame 5 is cylindrical. The inner wall of the bearing frame 5 is provided with the screening mechanism 6. A feeding mechanism 7 is provided on one end surface of the screening frame 1 at the position corresponding to the pouring frame 605. A transfer mechanism 8 is provided on the side surface of the screening frame 1 near the feeding mechanism 7.

[0054] The following details the specific configuration and function of its screening mechanism 6, feeding mechanism 7, and transfer mechanism 8. For example... Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, Figure 3 The internal structure of the support frame is shown. Figure 4 The screening mechanism and related structures are shown. Figure 5 The closed plate and related structures are shown. Figure 6 The internal structure and related structures of the screening rack are shown. Figure 7 The internal structure of the screening mechanism is shown. Figure 8 The limit rod, connecting plate, and associated structures are shown.

[0055] The screening mechanism 6 includes a screening cylinder 601, one end of which is fixedly connected to the surface of the rotating plate 4. The screening cylinder 601 has several screening holes 604 on its arc surface. A discharge frame 605 is fixedly connected to the surface of the bearing frame 5 corresponding to one end of the screening cylinder 601. A closing plate 606 is rotatably connected to the end of the screening frame 1 away from the drive motor 2. Positioning plates 607 are fixedly connected to both ends of the closing plate 606. The positioning plates 607 have an "L"-shaped cross-section. A positioning block 608 is fixedly connected to the side wall surface of the screening frame 1 at a position corresponding to the positioning plate 607. The positioning block 608 has a "U"-shaped cross-section. The inner wall of the positioning block 608 is inserted into the surface of the positioning plate 607. A moving rod 609 slides through the surface of the positioning block 608, one end of which is connected to the surface of the positioning plate 607. The movable rod 609 is fitted with a spring 610 on its arc surface. The two ends of the spring 610 are fixedly connected to the movable rod 609 and the positioning block 608, respectively. A fixed shaft 602 is fixedly connected to the surface of the rotating plate 4. Several auxiliary rods 603 are fixedly connected to the arc surface of the fixed shaft 602. A limit plate 611 is fixedly connected to the inner wall of the screening frame 1. A limit rod 612 slides through the inner wall of the limit plate 611. A connecting plate 613 is fixedly connected to one end of the limit rod 612. A pull ring 614 is rotatably connected to the arc surface of one end of the limit rod 612. The cross-sectional dimensions of the pull ring 614 are adapted to the cross-sectional dimensions of the limit rod 612. Several long hair columns 615 and several short hair columns 616 are fixedly connected to the lower surface of the connecting plate 613. The long hair columns 615 are nylon columns and the short hair columns 616 are alloy steel columns.

[0056] The effect achieved by the entire screening mechanism 6 is that when screening raw coal quickly and effectively, the screening operation can be carried out by using the screening mechanism 6 set in the bearing frame 5 of the screening frame 1. The raw coal is screened through the screening cylinder 601, and then flows into the screening frame 1 through the screening hole 604 and the bearing frame 5, which facilitates the screening and collection operation.

[0057] like Figure 9 , Figure 10 and Figure 11 As shown, Figure 9 Show the feeding mechanism, Figure 10 for Figure 9 Enlarged structural diagram at point A in the middle. Figure 11The feeding mechanism 7 includes four support plates 71, the bottom ends of which abut against the surface of the screening frame 1. A common material loading frame 79 is fixedly connected to the upper ends of the four support plates 71. A discharge frame 74 is fixedly connected through the lower surface of the material loading frame 79, and the surface of the discharge frame 74 is inserted into the inner wall of the pouring frame 605. The bottom cross-section of the support plates 71 is U-shaped. Support columns 72 are fixedly connected to the surface of the screening frame 1 at positions corresponding to the support plates 71. The arc surface of the support columns 72 engages with the surface of the support plates 71. The arc surface of the 2 is threaded with an extrusion shaft 73. The lower surface of the extrusion shaft 73 abuts against the surface of the support plate 71. A baffle 76 slides through the surface of the discharge frame 74. A connecting rod 75 slides through the arc surfaces on both sides of the baffle 76. One end of the connecting rod 75 is fixedly connected to the side wall of the discharge frame 74. An extrusion rod 77 is threaded through the arc surface on one side of the baffle 76. One end of the extrusion rod 77 abuts against the arc surface of the connecting rod 75. A pull rod 78 is fixedly connected to the surface of the baffle 76. The cross-section of the pull rod 78 is U-shaped.

[0058] The entire feeding mechanism 7 achieves the following effect: in order to facilitate the feeding of a large amount of raw coal into the screening cylinder 601, the raw coal is supported and placed by the loading frame 79, and the discharge port of the discharge frame 74 is opened and closed by the baffle 76 that slides through the surface of the discharge frame 74, so as to effectively and conveniently control the discharge of raw coal.

[0059] like Figure 12 and Figure 13 As shown, Figure 12 The transfer mechanism is shown. Figure 13 The structure of the transfer mechanism with a screen frame 87 inside is shown. The transfer mechanism 8 includes two insert blocks 82, one end of which is fixedly connected to the side wall surface of the screening frame 1. Insert frames 83 are slidably connected to the surfaces of the two insert blocks 82. The same transfer frame 81 is fixedly connected to the side of the two insert frames 83 that are close to each other. A fixed frame 84 is fixedly connected to one side surface of the transfer frame 81. A rotating frame 86 is rotatably connected to the inner wall of the fixed frame 84. Coil springs 85 are sleeved at both ends of the inner wall of the fixed frame 84. The two ends of the coil springs 85 are fixedly connected to the fixed frame 84 and the rotating frame 86, respectively. The screen frame 87 is slidably connected to the inner wall of the transfer frame 81. A clamping plate 88 is fixedly connected to the four corner surfaces of the screen frame 87. The cross-section of the clamping plate 88 is hook-shaped. The upper inner wall of the clamping plate 88 is engaged with the surface of the transfer frame 81.

[0060] The effect achieved by the entire transfer mechanism 8 is that when collecting and transferring the screened raw coal, it can be transported with the help of the transfer frame 81. The position is fixed by the insertion frame 83 on both sides of the transfer frame 81 and the insertion block 82 fixed on the side wall of the screening frame 1. After collection, the raw coal can be moved effectively and conveniently by the rotating frame 86 on one side of the transfer frame 81.

[0061] The overall working principle is as follows: During the processing of raw coal, screening is required. This is achieved using the screening mechanism 6 inside the screening frame 1. First, the drive motor 2 drives the transmission frame 3, which in turn rotates the entire rotating plate 4 and the screening cylinder 601. Simultaneously, the discharge frame 605 conveys the raw coal into the screening cylinder 601. The screening cylinder 601 then rotates and stirs the raw coal inside. The fixed shaft 602 and auxiliary rod 603 within the screening cylinder 601 further agitate the raw coal. After screening, the raw coal is then... The support frame 5 flows into the inner wall of the screening frame 1, and at the same time pulls the limiting rod 612 inside the screening frame 1, so that the limiting rod 612 drives the connecting plate 613 to stretch the bottom of the inner wall of the screening frame 1, thereby collecting the screened raw coal. During this process, the closing plate 606 on one side of the screening frame 1 can also be opened and closed. The positioning plates 607 fixed on both sides of the closing plate 606 are inserted into the positioning frame on the surface of the screening frame 1. At the same time, the moving rod 609 is stretched and limited by the tensile force generated by the spring 610, so as to facilitate and effectively screen the raw coal and then collect and clean it.

[0062] When screening raw coal, in order to facilitate the transportation of a large amount of raw coal into the screening cylinder 601, the material loading frame 79 is used for auxiliary operation. First, the material loading frame 79 is inserted into the support column 72 on the surface of the screening frame 1 with the support plate 71, and then the extrusion shaft 73 is rotated to fix it. Then, a large amount of raw coal is put into the material loading frame 79. At the same time, the discharge frame 74, which is fixed through the bottom of the material loading frame 79, is docked and fixed with the pouring frame 605. Then, during the screening process, the baffle 76 that slides through the surface of the discharge frame 74 is pulled to control the amount of coal discharged from the entire discharge frame 74.

[0063] When transferring the raw coal collected in the screening frame 1, it can be operated by the transfer mechanism 8. First, the transfer frame 81 is connected and fixed to the insert block 82 fixed to the side wall of the screening frame 1 by means of the insert frame 83 on both sides. Then, the closing plate 606 on one side of the screening frame 1 is opened. By operating the limit rod 612 and the connecting plate 613, the screened raw coal is transported into the transfer frame 81. At the same time, the screen frame 87 is used for secondary screening. Then, the rotating frame 86 on one side of the transfer frame 81 is pulled to move its position. At the same time, the torsional force generated by the coil spring 85 in the fixed frame 84 can effectively fix and limit the position of the rotating frame 86.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
