Description

Technical Field

[0001] This invention relates to the field of mineral technology, and specifically to a mineral powder filtration device. Background Technology

[0002] Rock powder refers to rock powder that can remain in a floating state for a long time. It is used to prevent coal dust explosions. The content of combustibles in it does not exceed 5%, the content of free silica does not exceed 10%, and it does not contain any harmful or toxic mixtures. During the production of rock powder, there will be crushed stones that have not been ground into powder. Among them, the mining rock powder filter device is a key piece of equipment in mining production. It is used to separate crushed stones and impurities from the rock powder to ensure that the rock powder meets safety standards. Therefore, a filter device is required in the rock powder handling process.

[0003] Compared with existing rock powder filtration devices, the following defects still exist: Existing rock powder filtration devices use dual-cylinder filtration, which solves the problem of saving filtration time for large quantities of rock powder and eliminating the need for manual impurity removal. However, in actual use, some rock powder will still remain in the crushed stone. Using only the single filtration method will cause a small amount of rock powder to flow out. At the same time, after screening and filtration are completed, it is impossible to effectively collect impurities such as crushed stone. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-7 As shown, the present invention is a mineral powder filtration device.

[0021] Example 1 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 In this invention, a technical solution is provided: a fixed mounting base 1, a filter box 3 fixedly mounted inside a fixed support leg 2 at the upper end of the fixed mounting base 1, two sets of vibrating frame plates 5 inside the filter box 3 for classifying and screening rock powder, a stirring blade 3022 for settling and drying rock powder at the lower end of the filter box 3, and a fixed mounting frame 6 fixedly connected to the filter box 3 on the lower surface of the vibrating frame plate 5.

[0022] Furthermore, a clearance groove 303 is provided at the right end of the filter box 3 to accommodate the movement of the vibrating frame plate 5, and an installation support plate 302 is fixedly installed at the lower end of the filter box 3, which enables the vibrating frame plate 5 to move up and down stably and in a limited manner within the filter box 3.

[0023] Furthermore, a dredging groove is provided on the inner side of the mounting plate 302, and a stirring blade 3022 is installed on the upper end of the mounting plate 302 to stir and dry the rock powder. This allows for stirring and drying operations after the rock powder is screened and filtered, thus avoiding residual moisture.

[0024] Furthermore, an inclined discharge plate 501 is fixedly installed on the right end of the vibrating frame plate 5, and a first filter screen plate 505 is provided on the inner side of the vibrating frame plate 5, which can filter and screen the ore powder.

[0025] Furthermore, the first filter plate 505 also includes a second filter plate 5051. The mesh size of the first filter plate 505 is smaller than that of the second filter plate 5051, which enables graded filtration and screening, thereby improving the filtration effect.

[0026] Furthermore, a vibration motor 502 connected to a damping spring 503 is provided at the lower end of the vibration frame plate 5. The damping spring 503 is located at the upper end of the flow guide plate 504 fixedly installed inside the filter box 3, which can drive the vibration frame plate 5 to vibrate up and down through the damping spring 503 when the vibration motor 502 is turned on.

[0027] Specifically, first, the fixed mounting base 1 is placed stably in a fixed location. Then, the ore material is sequentially and quantitatively fed into the feed frame 4. When the ore material enters the filter box 3 along the inclined bottom of the feed frame 4, the vibration motor 502 is turned on to start operation. Since the upper end of the vibration motor 502 is fixedly mounted with the vibration frame plate 5, and the lower end of the vibration motor 502 is mounted at the four corners of the upper end of the guide plate 504 through the damping springs 503, when the vibration motor 502 operates, it will drive the vibration frame plate 5 to move on the guide plate 504 through the damping springs 503. The material is vibrated and screened by reciprocating vibration. Since the inner side of the vibrating frame plate 5 is inclined to the right and the right end of the vibrating frame plate 5 is fixedly installed with the discharge plate 501 extending to the right end of the filter box 3 through the relief groove 303, the crushed stone and other impurities can be concentrated and discharged into the fixed installation frame 6 under the action of vibrating screening. Then, the screened rock powder enters the second filter screen plate 5051. Since the mesh size of the second filter screen plate 5051 is larger than that of the first filter screen plate 505, the rock powder can be filtered and screened again to improve the filtration effect.

[0028] When the first filter plate 505 and the second filter plate 5051 vibrate and screen the ore material, the filtered rock powder will flow downward along the fixed guide plate 301. Since the lower inner side of the fixed guide plate 301 is equipped with a mounting support plate 302, when the first servo motor 3021 is turned on to rotate the stirring blade 3022, the downward-flowing rock powder can be stirred and dried to remove the residual moisture in the rock powder. At the same time, the dried rock powder will be discharged directly into the receiving box 7 through the groove opened on the inner side of the mounting support plate 302 for unified collection, thereby improving the filtration effect. The receiving box 7 is placed on the upper end of the fixed mounting base 1 and can be movably connected. The upper front and rear sides of the receiving box 7 are open to avoid being blocked by the mounting support plate 302 when the receiving box 7 is taken out.

[0029] Example 2 Please see Figure 2 , Figure 3 and Figure 5In this invention, a technical solution is provided: a reciprocating screw 602 is provided on the inner side of the fixed mounting frame 6, which can reciprocate the connecting lug 603. A support crossbar 604 connected to the brush body 605 is fixedly installed at the inner end of the connecting lug 603. The upper surface of the brush body 605 is fitted with the lower surface of the first filter screen 505. When the third servo motor 601 is turned to rotate the reciprocating screw 602, the connecting lug 603 and the support crossbar 604 are driven to move laterally and reciprocally as a whole, so that the brush body 605 can clean the lower surfaces of the first filter screen 505 and the second filter screen 5051. Furthermore, the upper surface of the brush body 605 is fitted to the lower surface of the first filter screen 505; the inner side of the brush body 605 is also provided with a through hole 606 to facilitate the passage of the air blowing head 607, the air blowing head 607 is located at the upper end of the support crossbar 604 and is connected to a corrugated pipe 608 on the left side, and an air pump 609 fixedly connected to the fixed mounting frame 6 is provided on the left side of the corrugated pipe 608.

[0030] Specifically, in conjunction with Embodiment 1, since the lower end of the vibrating frame plate 5 is provided with a fixed mounting frame 6 that is fixedly installed with the filter box 3, after the vibrating frame plate 5 has been vibrating and screening for a period of time, the third servo motor 601 can be turned to rotate the reciprocating screw 602, so that the connecting lug 603 threadedly connected to the reciprocating screw 602 drives the support crossbar 604 to perform left and right lateral reciprocating motion within the fixed mounting frame 6. Since the upper surface of the brush body 605 provided at the upper end of the support crossbar 604 is in close contact with the lower surface of the first filter screen plate 505 and the second filter screen plate 5051, the left and right lateral reciprocating motion of the brush body 605 can be used to sweep away the rock powder adhering to the lower surface of the first filter screen plate 505 and the second filter screen plate 5051, so as to avoid affecting the subsequent screening effect and reduce clogging.

[0031] The reciprocating sweeping of the brush body 605 reduces the efficiency of subsequent manual cleaning and increases the filtration effect during actual use. In addition, the fixed installation frame 6 is designed with an inner opening to prevent impurities such as gravel from entering the interior of the fixed installation frame 6 and causing blockage of the reciprocating screw 602.

[0032] The air blowing head 607 penetrates the inner side of the brush body 605 through the through hole 606, and is connected to the air pump 609 through the corrugated pipe 608. When the brush body 605 moves laterally on the lower surface of the first filter plate 505 and the second filter plate 5051, it simultaneously sweeps away the rock powder adhering to the lower surface of the first filter plate 505 and the second filter plate 5051, and blows out the blockages in the filter holes inside the first filter plate 505 and the second filter plate 5051 through the airflow ejected by the air blowing head 607, thus preventing the rock powder and other materials from clogging the filter. The filter holes may not be cleaned properly by brushing. Since the air blower 607 is connected to the air pump 609 through the corrugated pipe 608, and the air pump 609 is fixedly installed on the left end of the fixed mounting frame 6, and the corrugated pipe 608 is a hollow negative pressure telescopic pipe that can extend or retract with the lateral movement of the support crossbar 604, thereby avoiding air leakage. The airflow combined with the brush body 605 achieves high cleaning efficiency. At this time, the rock powder blockage blown out by the airflow will return to the top of the first filter screen 505 and the second filter screen 5051 for further screening, while the unscreened material will be vibrated and discharged.

[0033] Example 3 Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 In this invention, a technical solution is provided: a material collection box 8 is provided at the right end of the filter box 3, located on the upper end of the fixed mounting base 1, a conveyor belt 804 with circulating motion is provided on the inner side of the material collection box 8, and rubber spacers 805 are evenly distributed on the outer surface of the conveyor belt 804.

[0034] Furthermore, the inner side of the collection box 8 is provided with a guide groove 801 that is inclined to the right. The linkage roller shaft 803 and the conveyor belt 804 are connected in a nested manner, which can drive the support crossbar 604 to rotate when the reciprocating screw 602 is opened and the connecting ear block 603 is rotated.

[0035] Furthermore, rubber partitions 805 are evenly distributed on the outer surface of the conveyor belt 804, and rubber side plates 806 are provided at both the front and rear ends of the conveyor belt 804. The upper outer surface of the conveyor belt 804 is fitted with the inner wall of the feed frame 4, which can scrape up the gravel and impurities deposited in the third servo motor 601 under the action of the brush body 605.

[0036] Specifically, in conjunction with Embodiments 1 and 2, after the vibrating frame plate 5 vibrates and screens the ore material, the crushed stone and other impurities will be concentrated and discharged into the collection box 8. Since the collection box 8 has a guide groove 801 that is inclined to the lower right, the second servo motor 802 is turned on to rotate the linkage roller shaft 803, which can drive the conveyor belt 804 wrapped around the outside of the linkage roller shaft 803 to rotate. The rubber spacers 805 that are evenly distributed on the outer surface of the conveyor belt 804 can scrape up the crushed stone and impurities at the bottom of the guide groove 801, and then transport them to the upper end along the conveyor belt 804, and then enter the filter box 3 again along the feed frame 4 for vibrating screening. This avoids some rock powder adhering to the crushed stone or impurities without being removed. Secondary screening improves the utilization rate of rock powder and avoids waste caused by residue.

[0037] The conveyor belt 804 is equipped with rubber side plates 806 at both ends, which are respectively attached to the guide trough 801 and the inner wall of the feed frame 4. These side plates can shield the gravel and impurities being conveyed and prevent them from falling off from the outside.

[0038] The rubber partition 805 and the rubber side plate 806 are both made of high-hardness polyurethane rubber, which has a wear resistance far exceeding that of ordinary rubber, strong impact resistance, and high surface smoothness, which can reduce the adhesion of gravel and is suitable for high-speed scraping scenarios and harsh outdoor environments.

[0039] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
