Description

Technical Field

[0001] The utility model relates to the technical field of titanium concentrate screening, in particular to a screening machine for separating titanium concentrates of different grades used in titanium concentrate processing. Background Art

[0002] Titanium concentrate is mined from ilmenite or titanomagnetite and is the raw material for producing titanium dioxide, which has a wide range of uses. During the mining and production process, titanium concentrate will produce ore particles of different coarse and fine categories. Titanium concentrates of different coarse and fine categories have different uses. Therefore, during mining and production processing, titanium concentrates of different grades need to be screened, and this type of screening machine is needed for screening.

[0003] However, when existing screening machines screen titanium concentrate, there is usually only one screening process inside the machine, which results in fewer grade levels of titanium concentrate during the screening process. When faced with refined usage, the titanium concentrate screened by this screening machine still needs to be screened again before it can be put into use, thereby lengthening the mining and processing cycle of the titanium concentrate and reducing the processing efficiency of the titanium concentrate. In this regard, this design proposes a screening machine for diverting titanium concentrates of different grades for titanium concentrate processing. Utility Model Content

[0020] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0021] The examples are as follows:

[0022] The utility model provides Figure 1-4 The screen shown is a screen for separating titanium concentrates of different grades for processing titanium concentrates, comprising a screen body 1 and a separation screening mechanism 2 installed inside the screen body 1;

[0023] The diversion screening mechanism 2 includes a feed trough 201 provided on the inner wall of the screening machine body 1, a first diversion trough 202 is installed on the upper end of the inner wall of the feed trough 201, a second diversion trough 203 is installed at the bottom of the first diversion trough 202, a third diversion trough 204 is installed at the bottom of the second diversion trough 203, a mounting groove 205 is provided on one side of the top of the first diversion trough 202 and one side of the top of the second diversion trough 203, a screening net 206 is installed on the inner walls of the two mounting grooves 205, an arc guide plate 207 is installed at the outer edge of the mounting groove 205 at the bottom of the first diversion trough 202, and a combing net 206 is rotatably installed on the inner wall of the feed trough 201 above the first diversion trough 202. Roller 208, and protruding and toggling structures are set on both sides of the combing roller 208, and the rotation speed is relatively slow. Therefore, during the time interval when the two protruding parts are close to the first diverter trough 202, the ore can roll through the combing roller 208 to screen it and discharge large particles of ore at the same time. The toggled ore will roll back and forth on the screening net 206, so that the small particles of ore contained therein are fully screened out. The hole sizes of the screening net 206 on the first diverter trough 202 and the screening net 206 on the second diverter trough 203 are different. The hole diameter of the screening net 206 on the first diverter trough 202 is larger than the hole diameter of the screening net 206 at the upper end of the second diverter trough 203;

[0024] Furthermore, a first discharge trough 209 is installed above one side of the screening machine body 1, a second discharge trough 210 is installed below the first discharge trough 209 on one side of the screening machine body 1, and a third discharge trough 211 is installed in the middle position of the other side of the screening machine body 1, and the inner wall of the first discharge trough 209 is connected to the inner wall of the first diversion trough 202, the inner wall of the second discharge trough 210 is connected to the inner wall of the third diversion trough 204, and the inner wall of the third discharge trough 211 is connected to the inner wall of the second diversion trough 203.

[0025] A motor 212 is installed at the upper edge of one side of the screening machine body 1, and one end of the combing roller 208 passes through the outer wall of one side of the screening machine body 1 and is fixedly connected to the output end of the motor 212;

[0026] Furthermore, a cleaning slot 3 is provided on the other side of the screening machine body 1. A sealing plate 4 is hingedly provided on the inner side of the inner wall of the cleaning slot 3. A protective cover 5 is hingedly provided on the outer side of the inner wall of the cleaning slot 3. The screening net 206 can be disassembled and assembled in the mounting slot 205. After the protective cover 5 is opened, the sealing plate 4 in the cleaning slot 3 is rotated open to open the side wall of the feed slot 201, so that the staff can take out the screening net 206 for cleaning to prevent blockage.

[0027] Furthermore, a plurality of gaskets 6 are interspersed on one side of the protective cover 5, and a spring 7 is sleeved on the outer wall of one end of each gasket 6, and one end of each spring 7 is fixedly connected to one side of the protective cover 5. A feed hopper 8 is installed on one side of the top of the screening machine body 1, and the inner wall of the feed hopper 8 is connected to the inner wall of the feed trough 201. When in use, the sealing plate 4 is closed and then the protective cover 5 is closed and fixed with a lock. When locked, the gasket 6 will be squeezed on the sealing plate 4 and the spring 7 will be compressed to make the sealing plate 4 closely contact the cleaning trough 3 to prevent leakage during screening.

[0028] Working principle: When using the screening machine for separating titanium concentrates of different grades in the titanium concentrate processing scheme of this design, first, the titanium concentrate material is put into it through the feed hopper 8, so that it enters the first diversion trough 202 from the feed trough 201, and the first diversion trough 202, the second diversion trough 203 and the third diversion trough 204 are all installed at an angle, and the ore rolls on it and is screened through the screening net 206 on the first diversion trough 202, so that small particles of titanium concentrate fall on the arc guide plate 207, roll, and slide onto the second diversion trough 203, while large particles of ore are directly discharged from the first discharge trough 209, and the ore falling on the second diversion trough 203 continues to roll and is screened again through the screening net 206 at its upper end to separate the finer ore. The particles are screened and fall into the third diverter trough 204 below, and the ore after re-screening is discharged from the third discharge trough 211 and the second discharge trough 210 respectively, so that the screening machine can screen the ore at multiple levels, and a combing roller 208 is arranged above the first diverter trough 202, which is driven by a motor 212 to rotate continuously and move the ore entering the first diverter trough 202 in large quantities, so that it can be fully screened from the screening net 206. In addition, the ore that falls after screening is reduced in number, and is guided by the arc guide plate 207 so that it can also be fully screened and leaked on the screening net 206 on the second diverter trough 203, thereby improving the screening efficiency and screening fineness of the device for titanium concentrate, reducing the probability of re-screening during later processing, and thereby improving the processing efficiency of titanium concentrate items.
