Description

Technical Field

[0001] This invention belongs to the field of water filtration technology, and specifically provides a multi-stage water filtration device for the front end of water used in mining areas. Background Technology

[0002] In mining and related operations, the supply of clean water often faces significant challenges due to remote locations, complex terrain, and poor transportation conditions. Mining operations frequently require the use of local natural water bodies (such as lakes and rivers), but these water sources typically contain a large amount of impurities, including broken branches, fallen leaves, gravel, silt, and other solid debris. Direct use of such unfiltered water can easily cause blockages in mining equipment (especially the nozzles of spraying and cooling systems), affecting not only the normal operation of the equipment but also severely slowing down the overall project progress.

[0003] Currently, while some simple filtration methods exist for the pretreatment of water in mining areas, they generally suffer from incomplete filtration, difficult cleaning and maintenance, and low levels of automation. Especially when treating outdoor water sources containing a large amount of irregular impurities, existing filtration devices often lack effective multi-stage filtration and self-cleaning mechanisms, leading to easy filter clogging, frequent cleaning, and heavy manual workload, making it difficult to meet the needs of efficient and continuous operations in mines. Therefore, there is an urgent need for a front-end water treatment device that can adapt to harsh water intake environments, achieve efficient multi-stage filtration, and has automatic cleaning capabilities. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a multi-stage water filtration device for the front end of water supply in mining areas.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a multi-stage water filtration device for the front end of mining water supply, comprising a base, a filter barrel fixedly connected to the upper surface of the base, a conveying pipe connected to the outer side of the filter barrel, a multi-stage filter drill rod connected to the outer end of the conveying pipe, an electric push rod fixedly connected to the lower surface of the base, a telescopic rod of the electric push rod passing through the base and fixedly connected to a vertical rod, a support rod fixedly connected to the lower end of the vertical rod in an array, a rigid fan-shaped filter plate assembled between two adjacent support rods, an elastic cloth fixedly installed between the rigid fan-shaped filter plate and the support rod, a hook tension spring assembled between each rigid fan-shaped filter plate and the vertical rod, and an inclined rubber membrane fixedly installed on the outer circle of the filter barrel.

[0006] Furthermore, the outer wall of the filter barrel is provided with four first mounting slots, each of which is rotatably fitted with a rotating shaft. A toggle plate is fixedly installed on the outer circle of the rotating shaft. A sliding hole is provided at the upper end of the filter barrel wall. The four sliding holes are connected to the four first mounting slots. A rack is slidably fitted in each of the four sliding holes. Gears are fixedly installed on the outer circle of the four rotating shafts. The four gears mesh with the four racks respectively. The toggle plate is located below the inclined rubber membrane.

[0007] Furthermore, a first arc-shaped block is fixedly installed on the upper end of each rack, and a first arc-shaped groove corresponding to the first arc-shaped block is opened on the lower surface of each rigid fan-shaped filter plate. A first spring is fixedly installed between the bottom end of the rack and the bottom surface of the inner cavity of the sliding hole.

[0008] Furthermore, each of the rigid sector-shaped filter plates has a hanging rod fixedly installed on its upper surface. The outer circle of the vertical rod is slidably fitted with a sliding seat. The outer circle of the sliding seat is provided with four second mounting slots. Each of the second mounting slots is hinged with a guide rod. The hanging rod has a sliding hole on its surface, and the guide rod passes through the sliding hole. Each guide rod is fixedly connected with an electric actuator, and the output end of the electric actuator is fixedly connected to the hanging rod.

[0009] Furthermore, a support rod is fixedly installed on the upper surface of the base, a crossbar is fixedly installed at the upper end of the support rod, an elastic arc block is fixedly installed at one end of the crossbar, a slot is provided on the outer side of the sliding seat, the slot cooperates with the elastic arc block, a fixing block is fixedly installed on the outer circle of the vertical rod, and a third spring is fixedly installed between the fixing block and the sliding seat.

[0010] Furthermore, the upper end of the inner wall of the filter barrel is provided with an inclined surface.

[0011] The beneficial effects of using this invention are: 1. This invention comprises a core filtration unit consisting of a vertical rod, a support rod, and multiple rigid sector-shaped filter plates, all controlled by an electric actuator. This design not only effectively intercepts large debris in the water, achieving reliable primary filtration, but also, through the coordinated operation of the electric actuator, sliding seat, and suspension rod, enables the filter plate assembly to automatically lift, tilt, and vibrate. This automatically discharges the trapped debris onto the tilted rubber membrane, greatly reducing the workload of manual cleaning and ensuring the continuity and efficiency of the filtration operation.

[0012] 2. This invention designs a transmission mechanism consisting of a rack, gears, a rotating shaft, and a actuating plate, which cooperates with the first arc-shaped block and the first arc-shaped groove at the bottom of the rigid fan-shaped filter plate. During the process of the filter plate tilting to discharge slag, this mechanism can convert the linear motion of the filter plate into the reciprocating oscillation of the actuating plate, continuously actuating the tilted rubber membrane to generate vibration. This vibration effect can effectively promote the sliding off of debris, significantly reducing the residue of debris on the surface of the tilted rubber membrane, and further reducing subsequent maintenance costs.

[0013] 3. The present invention is equipped with a hook spring, elastic cloth, third spring and elastic arc block and slot cooperation, which not only ensures the stability of the rigid fan-shaped filter plate in the filtration state, but also generates controllable vibration during the lifting and cleaning process, so that the residual attachments on the surface of the rigid fan-shaped filter plate are effectively shaken off, ensuring the thoroughness of each cleaning, improving the overall filtration efficiency and device reliability.

[0014] 4. This invention features a compact overall structure and is designed for the harsh water intake environment of mining areas. It can effectively pre-treat lake water, river water, etc., removing most solid impurities. This significantly reduces the load on downstream precision water treatment equipment, avoids project interruptions due to water quality issues, and enables mining equipment to maintain stable operation even in remote mountainous areas. It has strong practicality and promotional value. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Reference Figures 1 to 6 A multi-stage water filtration device for mining area water supply includes a base 1, a filter barrel 11 fixedly connected to the upper surface of the base 1, a conveying pipe 12 connected to the outer side of the filter barrel 11, a multi-stage filter drill rod connected to the outer end of the conveying pipe 12, an electric push rod 13 fixedly connected to the lower surface of the base 1, a telescopic rod of the electric push rod 13 passing through the base 1 and fixedly connected to a vertical rod 16, a support rod 17 fixedly connected to the lower end of the vertical rod 16, a rigid fan-shaped filter plate 18 assembled between two adjacent support rods 17, an elastic cloth 181 fixedly installed between the rigid fan-shaped filter plate 18 and the support rod 17, a hook tension spring 182 assembled between each rigid fan-shaped filter plate 18 and the vertical rod 16, an inclined rubber membrane 19 fixedly installed on the outer circle of the filter barrel 11, and an inclined surface 42 opened at the upper end of the inner wall of the filter barrel 11.

[0024] Specifically, the upper surface of the rigid fan-shaped filter plate 18 is fixedly equipped with a hanging rod 3, and the outer circle of the vertical rod 16 is slidably fitted with a sliding seat 31. The outer circle of the sliding seat 31 is provided with four second mounting slots, and a guide rod 32 is hinged in each of the second mounting slots. The surface of the hanging rod 3 is provided with a sliding hole, and the guide rod 32 passes through the sliding hole. Each guide rod 32 is fixedly connected with an electric actuator 33, and the output end of the electric actuator 33 is fixedly connected to the hanging rod 3.

[0025] During operation, lake water is first poured into the filter tank 11. The lake water passes through four rigid fan-shaped filter plates 18, filtering out impurities mixed in with the lake water. The impurities remain on the surface of the four rigid fan-shaped filter plates 18. Then, the electric push rod 13 pushes the vertical rod 16 upward. The vertical rod 16 drives the support rod 17 and the rigid fan-shaped filter plates 18 upward, causing the impurities to leave the lake water in the filter tank 11. When the rigid fan-shaped filter plates 18 move upward above the filter tank 11, the hook spring 182 pulls the rigid fan-shaped filter plates 18 at an angle, keeping the rigid fan-shaped filter plates 18 balanced. When the electric actuator 33 pushes the lifting rod 3 to slide along the guide rod 32, the rigid fan-shaped filter plate 18 at the lower end of the lifting rod 3 moves outward and stretches the elastic cloth 181. The center of gravity of the lifting rod 3 and the rigid fan-shaped filter plate 18 as a whole moves outward. The pulling force of the hook spring 182 is insufficient to keep the rigid fan-shaped filter plate 18 balanced, so the rigid fan-shaped filter plate 18 is tilted downward. The debris on the tilted rigid fan-shaped filter plate 18 slides down and falls on the tilted rubber membrane 19, which makes it easy to discharge the debris from the filter barrel 11 and facilitates manual cleaning of the debris from the outside.

[0026] Afterwards, the electric push rod 13 pulls the vertical rod 16 back down, and the four rigid fan-shaped filter plates 18 re-enter the filter barrel 11 along the inclined plane 42 for the next treatment; through the rigid fan-shaped filter plates 18, impurities in the lake water are filtered out, and large impurities are pre-treated in the lake water, so that the mining water demand equipment can be adapted to remote mining areas, reduce the water supply pressure of the project, and avoid affecting the progress of the project.

[0027] Specifically, the outer wall of the filter barrel 11 is provided with four first mounting slots, each of which is rotatably fitted with a rotating shaft 2. A toggle plate 21 is fixedly installed on the outer circle of the rotating shaft 2. The upper end of the filter barrel 11 is provided with sliding holes 22, which are connected to the four first mounting slots. Each of the four sliding holes 22 is slidably fitted with a rack 23. Gears 24 are fixedly installed on the outer circle of the four rotating shafts 2. The four gears 24 mesh with the four racks 23 respectively. The toggle plate 21 is located below the inclined rubber membrane 19.

[0028] Specifically, a first arc-shaped block 25 is fixedly installed on the upper end of the rack 23, and a first arc-shaped groove 26 corresponding to the first arc-shaped block 25 is opened on the lower surface of the rigid fan-shaped filter plate 18. A first spring 28 is fixedly installed between the bottom end of the rack 23 and the bottom surface of the inner cavity of the sliding hole 22.

[0029] After the debris falls onto the inclined rubber membrane 19, multiple trash cans 111 are placed around the filter bucket 11 on the upper side of the base 1. Multiple arc-shaped grooves 112 are arranged in an array with the filter buckets 11 on the upper side of the inclined rubber membrane 19. The area between adjacent arc-shaped grooves 112 is an arched surface, which facilitates the accumulation of debris in the arc-shaped grooves 112. The arc-shaped grooves 112 are arranged corresponding to the trash cans 111.

[0030] The vibration of the inclined rubber membrane 19 causes debris on its surface to first gather in the arc-shaped groove 112, and then fall into the trash can 111. When the rigid sector-shaped filter plate 18 tilts outward, the bottom surface of the rigid sector-shaped filter plate 18 presses against the first arc-shaped block 25, pressing the first arc-shaped block 25 downward. Under the action of the first spring 28, the first arc-shaped block 25 abuts against the bottom surface of the rigid sector-shaped filter plate 18. When the four rigid sector-shaped filter plates 18 move outward, when the first arc-shaped block 25 enters the first arc-shaped groove 26, the first arc-shaped block 25 moves upward under the action of the first spring 28. The first arc-shaped block 25 drives the rack 23 to move upward, and the rack 23 drives the gear 24 to rotate. The gear 24 drives the rotating shaft 2 to rotate. As the actuating plate 21 rotates, the fan-shaped filter plate 18 continues to descend and presses down on the rack 23. The first arc-shaped block 25 slides on the lower surface of the fan-shaped filter plate and slides out of the first arc-shaped groove 26. The first spring 28 is compressed and stored again. When the first arc-shaped block 25 slides to the next first arc-shaped groove 26, the first spring 28 pushes the rack 23 upward again, causing the first arc-shaped block 25 to enter the first arc-shaped groove 26. The block slides up and down for a short time, causing the actuating plate 21 to rotate back and forth, actuating the rubber membrane 19. This causes the inclined rubber membrane 19 to vibrate, shaking off the debris on the surface of the inclined rubber membrane 19 and placing it in the trash can, reducing the amount of debris remaining on the surface of the inclined rubber membrane 19 and minimizing the amount of cleaning work.

[0031] Figure 5 The diagram shows the structure for cleaning debris. In actual application, the length of the guide rod 32, the size of the rigid fan-shaped filter plate 18, and the positions of the multiple first arc-shaped grooves 26 need to be adjusted and set according to the actual situation. This allows the first arc-shaped block 25 to enter the first arc-shaped groove 26 in sequence during the outward movement of the hanging rod 3, thereby repeatedly applying and releasing pressure on the rack 23, which in turn causes the agitator plate 21 to swing and shake off the debris.

[0032] because Figure 5 This is for illustrative purposes only, so the structure of the support rod 17 is not shown, and the support rod 17 is still in a horizontal position.

[0033] Specifically, a support rod 35 is fixedly installed on the upper surface of the base 1, a crossbar 36 is fixedly installed at the upper end of the support rod 35, an elastic arc block 37 is fixedly installed at one end of the crossbar 36, a slot 38 is opened on the outer side of the sliding seat 31, the slot 38 cooperates with the elastic arc block 37, a fixing block 4 is fixedly installed on the outer circle of the vertical rod 16, and a third spring 41 is fixedly installed between the fixing block 4 and the sliding seat 31.

[0034] As the vertical rod 16 moves upward, it pulls the support rod 17 and the rigid sector-shaped filter plate 18 upward. When the rigid sector-shaped filter plate 18 leaves the filter barrel 11, the elastic arc-shaped block 37 at one end of the horizontal rod 36 contacts one side of the sliding seat 31. When the elastic arc-shaped block 37 enters the slot 38, the elastic arc-shaped plate 37 blocks the sliding seat 31 from moving upward further. The vertical rod 16 drives the fixed block 4 to continue upward, and the third spring 41 is compressed and stores force. At this time, the vertical rod 16 pulls the support rod 17 upward, causing... The support rod 17 drives the rigid sector-shaped filter plate 18 to move upward, while the sliding seat 31 remains stationary, keeping the guide rod 32 and the hanging rod 3 stationary. The hanging rod 3 abuts against the edge of the rigid sector-shaped filter plate 18, causing the rigid sector-shaped filter plate 18 to tilt downward on the outside, allowing debris to slide down. When the third spring 41 is compressed to a certain extent (the greater the compression of the third spring 41, the stronger its elastic force), the restoring elastic force of the third spring 41 is greater than the force of the elastic arc-shaped block 37 locking the slot 38, and the third spring 41 pushes the sliding seat. 31 moves upward (the elastic arc block 37 deforms and avoids, releasing the compressive force of the third spring 41), causing the elastic arc block 37 to disengage from the slot 38. The elastic arc block 37 is compressed, and the sliding seat 31 moves upward. When the elastic arc block 37 contacts the next slot 38, the elastic arc block 37 enters the slot 38. At this time, the third spring 41 has released part of its elastic force. At this time, the force of the elastic arc block 37 holding the slot 38 is greater than the remaining elastic force of the third spring 41. At this time, the vertical rod 16 moves upward, and the third spring 41 continues... After being compressed and stored, the third spring 41, with its elastic force greater than the force of the elastic arc block 37 locking the slot 38, pushes the sliding seat 31 upward again. This causes the rigid fan-shaped filter plate 18 to vibrate up and down repeatedly in a tilted state, shaking off the debris remaining on the surface of the rigid fan-shaped filter plate 18, further cleaning the debris and reducing the difficulty of cleaning. At the same time, in this process, the electric push rod 33 and the hanging rod 3 can be used to adjust the overall tilt angle of the rigid fan-shaped filter plate 18, further improving the efficiency and effect of debris shaking.

[0035] In use, lake water is first poured into the filter tank 11. The lake water passes through four rigid fan-shaped filter plates 18, filtering out impurities mixed in with the lake water. The impurities remain on the surface of the four rigid fan-shaped filter plates 18. Then, the electric push rod 13 pushes the vertical rod 16 upward. The vertical rod 16 drives the support rod 17 and the rigid fan-shaped filter plates 18 upward, causing the impurities to leave the lake water in the filter tank 11. When the rigid fan-shaped filter plates 18 move upward above the filter tank 11, the hook spring 182 pulls the rigid fan-shaped filter plates 18 at an angle, keeping the rigid fan-shaped filter plates 18 balanced. When the electric actuator 33 pushes the lifting rod 3 to slide along the guide rod 32, the rigid fan-shaped filter plate 18 at the lower end of the lifting rod 3 moves outward and stretches the elastic cloth 181. The center of gravity of the lifting rod 3 and the rigid fan-shaped filter plate 18 as a whole moves outward. The pulling force of the hook spring 182 is insufficient to keep the rigid fan-shaped filter plate 18 balanced, so the rigid fan-shaped filter plate 18 is tilted downward. The debris on the tilted rigid fan-shaped filter plate 18 slides down and falls on the tilted rubber membrane 19, which makes it easy to discharge the debris from the filter barrel 11 and facilitates manual cleaning of the debris from the outside.

[0036] The electric push rod 13 pushes the vertical rod 16 to drive the fixed block 4 to continue upward. The third spring 41 is compressed and stores force. At this time, the vertical rod 16 pulls the support rod 17 to move upward. The sliding seat 31 remains stationary relative to the support rod 17. The hanging rod 3, guide rod 32, and rigid fan-shaped filter plate 18 rotate relative to the sliding seat 31 as a whole, causing the rigid fan-shaped filter plate 18 to tilt downward. Through vibration, the debris remaining on the surface of the rigid fan-shaped filter plate 18 is shaken off.

[0037] The above content is only a preferred embodiment of the present invention. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of the present invention. As long as these changes do not depart from the concept of the present invention, they all fall within the protection scope of the present invention.
