Description

Technical Field

[0001] The present application relates to the technical field of ore sorting equipment, and in particular to an iron ore grinding and classifying device. Background Art

[0002] Ore refers to a mineral aggregate mined from an ore body for industrial use. After the ore is mined, the operator crushes the ore according to actual needs, so that the ore is broken into crushed ores of different sizes, so that the operator can choose crushed ores of different sizes according to different usage scenarios.

[0003] After the crushed ore (hereinafter referred to as "ore") is broken, a grading device or a screening device is required. Among them, the iron ore grinding and grading device is one of the important equipment in the iron ore beneficiation process. The basic principle of the iron ore grinding and grading device is to sort the originally mixed and disordered ore into several crushed ore piles with different particle size ranges according to a certain particle size range, so that the operator can select the ore of the required particle size from the ore pile.

[0004] Common grading devices require the ore to pass through several screening devices in sequence, so as to screen different particle sizes in sequence to obtain ore in different particle size ranges. Ore sorting operations performed through the above-mentioned ore grading devices restrict the efficiency of ore sorting operations to a certain extent and increase the construction cost of ore sorting. Utility Model Content

[0005] In order to improve the operating efficiency of ore sorting, the present application provides an iron ore grinding and classifying device.

[0006] The present application provides an iron ore grinding and classifying device, which adopts the following technical solution:

[0007] An iron ore grinding and grading device comprises a body, wherein a channel 1 for ore to pass through is opened in the body, the bottom wall of the channel 1 is arranged obliquely, a plurality of channels 2 are opened in the bottom wall of the channel 1, the plurality of channels 2 are distributed along the length direction of the channel 1, each of the channels 2 is interconnected with the channel 1, a screen is installed in each of the channels 2, and the apertures of the plurality of screens gradually increase from high to low.

[0008] Through the above technical solution, when the operator needs to sort the ore, the ore is injected into channel one from the higher end of channel one at a certain speed, so that the ore gradually slides downward along the bottom wall of channel one.

[0009] In the process of ore 1 sliding along the bottom wall of channel 1, the ore will contact several screens in turn. Since the apertures of the screens gradually increase from high to low, the ore with smaller particle size can pass through the high screen and enter the corresponding channel 2 to complete the primary ore sorting, while the ore with larger particle size will continue to slide downward along the bottom wall of channel 1. The sorting principle is the same as above, and the sorting of ores with different particle sizes is gradually completed.

[0010] Operators use this equipment to sort the ore. Since this equipment does not need to pass the ore through several screening devices, the time required for ore sorting is shortened, and the number of equipment required for ore sorting is reduced, thereby improving the operating efficiency of ore sorting and reducing the construction cost of ore sorting.

[0011] In a preferred example, the utility model can be further configured as follows: the bottom wall of the channel one includes a plurality of screening sections and a plurality of acceleration sections, the plurality of screening sections and the plurality of acceleration sections are staggered with each other, the inclination angle of the acceleration section is greater than the inclination angle of the screening section, the plurality of screening sections and the plurality of channels two are arranged in a one-to-one correspondence, and the channel two is arranged at the corresponding screening section.

[0012] Through the above technical solution, when the ore slides in the acceleration section, under the action of gravity, it can obtain a large traction force downward along the slope, so that the ore slides along the channel, so that the ore passes through several screens.

[0013] When the ore slides in the screening section, since the inclination angle of the acceleration section is greater than the inclination angle of the screening section, the traction force of the ore along the downward slope can be reduced. On the basis of ensuring the sliding of the ore, the sliding time of the ore in the screening section is appropriately extended, so that the ore can be sorted more fully.

[0014] In a preferred example, the utility model can be further configured as follows: an inner wall of each of the channel 2 is provided with an installation groove, a fixing frame 1 and a fixing frame 2 are inserted into the installation groove, the screen is arranged between the fixing frame 1 and the fixing frame 2, a connecting piece is arranged between the fixing frame 1 and the fixing frame 2, and the fixing frame 1 and the fixing frame 2 are connected via the connecting piece.

[0015] Through the above technical solution, the screen is fixed between the fixed frame 1 and the fixed frame 2, and the installation of the screen is completed. The operator takes out the fixed frame 1 and the fixed frame 2 and the screen from the installation slot, and releases the connection between the fixed frame 1 and the fixed frame 2 by the connecting piece, so as to replace the screen with different apertures, thereby enabling the sorting of ores with different particle sizes.

[0016] In a preferred example, the utility model can be further configured as follows: the connecting member includes a bolt 1, the bolt 1 is penetrated on the fixing frame 1, and the bolt 1 is threadedly connected to the fixing frame 2.

[0017] With the above technical solution, after the operator takes out the fixing frame 1, the fixing frame 2 and the screen from the installation slot, he or she unscrews the bolts to release the clamping and fixing of the fixing frame 1 and the fixing frame 2 on the screen.

[0018] In a preferred example, the utility model can be further configured as follows: a rotating shaft is installed on the body, the rotating shaft is located above the mounting groove, a baffle is rotatably arranged on the rotating shaft, and the baffle and the fixed frame can abut and cooperate with each other.

[0019] Through the above technical solution, after the operator inserts the fixed frame 1, the fixed frame 2 and the screen into the installation groove on the machine body, the baffle is rotated to make the baffle and the fixed frame 1 abut against each other. At this time, under the obstruction of the baffle, the possibility of the fixed frame 1 and the screen sliding outward is reduced.

[0020] In a preferred example, the utility model can be further configured as follows: a second bolt is inserted into the baffle, and the second bolt is threadedly connected to the first fixing frame.

[0021] Through the above technical solution, when the operator rotates the baffle so that the baffle and the fixed frame 1 abut against each other, he then rotates bolt 2 so that bolt 2 is threadedly connected to the fixed frame 1, completing the connection between the baffle and the fixed frame 1, thereby reducing the possibility of the baffle rotating.

[0022] In a preferred example, the utility model can be further configured as follows: a delivery pipeline is installed on the machine body, the delivery pipeline and the second channel are interconnected, and the delivery pipeline is installed on the machine body by bolts three.

[0023] Through the above technical solution, the operator installs the conveying pipeline on the machine body so as to transport the sorted ore through the conveying pipeline.

[0024] In a preferred example, the utility model can be further configured as follows: the delivery pipeline includes a plurality of unit pipes, the plurality of unit pipes are sequentially connected end to end, and two adjacent unit pipes are connected via flanges.

[0025] Through the above technical solution, since the conveying pipeline is formed by connecting a plurality of unit pipes, the operator can change the length of the conveying pipeline by increasing or decreasing the number of unit pipes according to actual conditions.

[0026] In summary, the utility model includes the following beneficial technical effects:

[0027] 1. The ore is injected into channel 1 from the higher end of channel 1 and slides down along the bottom wall of channel 1. The ore with smaller particle size passes through the high screen and enters the corresponding channel 2 to complete the primary ore sorting. The ore with larger particle size will continue to slide down along the bottom wall of channel 1. The ore can be sorted with different particle sizes without passing through several screening devices, which shortens the time required for ore sorting and reduces the number of equipment required for ore sorting, thereby improving the operating efficiency of ore sorting and reducing the construction cost of ore sorting.

[0028] 2. The screen in this equipment is installed in a detachable manner, so that the operator can replace the screens with different apertures to sort ores with different particle sizes, thereby expanding the scope of application of this equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0036] An iron ore grinding and classifying device is disclosed in an embodiment of the present application.

[0037] See attached Figure 1 and attached Figure 2As shown, an iron ore grinding and grading device includes a body 1, and four universal wheels 5 are installed on the bottom surface of the body 1 to facilitate the movement and transportation of the device. The four universal wheels 5 are respectively installed at the four corners of the bottom surface of the body 1, and each universal wheel 5 is equipped with a foot brake to facilitate the positioning of the device.

[0038] See attached Figure 1 and attached Figure 2 As shown, a channel 11 is provided through the machine body 1, and the ore enters from one end of the channel 11 and slides out from the other end of the channel 11, and the bottom wall of the channel 11 is inclined. The bottom wall of the channel 11 includes a plurality of screening sections 101 and a plurality of acceleration sections 102, which are staggered and adjacent to each other, and the inclination angle of the acceleration section 102 is greater than the inclination angle of the screening section 101.

[0039] See attached Figure 1 and attached Figure 2 As shown, a channel 2 12 is opened downward at the screening section 101 of the bottom wall of each channel 1 11, and each channel 2 12 and channel 1 11 are interconnected. Several channels 11 are evenly distributed along the length direction of channel 1 11, and channel 2 12 is used for the sorted ore to slide out of the machine body 1. A screen 13 is installed at the top of each channel 2 12 for sorting the ore by particle size. The apertures of several screens 13 gradually increase from high to low, that is, the aperture of the screen 13 at the high position is smaller than the aperture of the screen 13 at the low position.

[0040] When the operator needs to sort the ore, the ore is injected into channel 11 from the higher end of channel 11, so that the ore gradually slides downward along the bottom wall of channel 11, and the ore with smaller particle size can pass through the high screen 13 into the corresponding channel 2 12 to complete the primary ore sorting, while the ore with larger particle size will continue to slide downward along the bottom wall of channel 11 to gradually complete the sorting of ores with different particle sizes.

[0041] Operators use this equipment to sort the ore. Since this equipment does not need to pass the ore through several screening devices, on the one hand, it shortens the time required for ore sorting, and on the other hand, it also reduces the number of equipment required for ore sorting, thereby improving the operating efficiency of ore sorting and reducing the construction cost of ore sorting.

[0042] See attached Figure 2 and attached Figure 3 As shown, the inner wall of each channel 12 is provided with a mounting groove 14 , which is opened at the top of the channel 12 , and the inclination angle of the mounting groove 14 is consistent with the inclination angle of the screening section 101 .

[0043] See attached Figure 3 and attached Figure 4As shown, a fixing frame 141 and a fixing frame 142 are inserted into the installation slot 14, the fixing frame 141 is located above the fixing frame 142, the screen 13 is arranged between the fixing frame 141 and the fixing frame 142, the fixing frame 141 and the fixing frame 142 are connected by a bolt 151, that is, the bolt 151 is penetrated on the fixing frame 141, the bolt 151 is threadedly connected to the fixing frame 142, and the head of the bolt 151 is flush with the outer wall of the fixing frame 141. A handle 3 is fixedly connected to the fixing frame 141, so that the operator can take out the fixing frame 141 from the installation slot 14.

[0044] The operator takes out the fixing frame 1 141 from the installation slot 14 by holding the handle 3, and drives the fixing frame 2 142 and the screen 13 to move outward, so that the operator can remove the bolts and replace the screen 13 with different apertures to expand the application range of the device.

[0045] See attached Figure 3 As shown, a plurality of rotating shafts 16 are installed on the machine body 1, and the plurality of rotating shafts 16 and the plurality of mounting slots 14 are arranged one by one. The rotating shafts 16 are located above the corresponding mounting slots 14, and a baffle 161 is rotatably arranged on the rotating shaft 16, and the baffle 161 and the fixing frame 1 141 can abut against each other. A second bolt 162 is inserted into the baffle 161, and the second bolt 162 is threadedly connected to the fixing frame 1 141.

[0046] After the operator inserts the fixing frame 141, the fixing frame 142 and the screen 13 into the installation groove 14, the baffle 161 is rotated to make the outer wall of the baffle 161 and the fixing frame 141 abut against each other, and then the bolt 162 is rotated to complete the connection between the baffle 161 and the fixing frame 141. Under the obstruction of the baffle 161, the possibility of the fixing frame 141 and the screen 13 sliding outward is reduced.

[0047] See attached Figure 1 As shown, a plurality of conveying pipes 2 are installed on the machine body 1 through bolts 3 21, and the plurality of conveying pipes 2 and the plurality of channels 2 12 are arranged one by one, and the conveying pipes 2 and the channels 2 12 are interconnected to facilitate the transmission of the sorted ore. Each conveying pipe 2 includes a plurality of unit pipes 22 connected end to end in sequence, and two adjacent unit pipes 22 are connected through flanges 221. The operator can increase or decrease the number of unit pipes 22 according to the actual situation to change the length of the conveying pipe 2.

[0048] See attached Figure 1 and attached Figure 2As shown, support plates 4 are detachably installed on both sides of the body 1, and the support plates 4 are "L"-shaped. The bottom surface of the support plates 4 is flush with the lowest point of the universal wheel 5. With the support of the support plates 4 on the body 1, the stability of the device during use is improved, and the possibility of the body 1 tipping over is reduced.

[0049] The implementation principle of this embodiment is: the operator injects the ore into channel 11 from the higher end of channel 11, and the ore gradually slides downward along the bottom wall of channel 11. The ore with smaller particle size passes through the high screen 13 and enters the corresponding channel 2 12 to complete the primary ore sorting. The ore with larger particle size will continue to slide downward along the bottom wall of channel 11 to gradually complete the sorting of ores with different particle sizes.

[0050] Since the equipment does not need to pass the ore through several screening devices, the time required for ore sorting is shortened and the number of equipment required for ore sorting is reduced, thereby improving the operating efficiency of ore sorting and reducing the construction cost of ore sorting.

[0051] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application in sequence. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
