A mine water treatment apparatus

Abstract

This invention relates to the technical field of wastewater treatment equipment and discloses a mine water treatment device. To solve the problem of traditional oil-water separation devices easily sucking up surface water, an oil-loving roller driven by a power unit is movably installed on a support frame. When the power unit drives the traveling unit forward, the oil-loving roller can push the floating oil on the water surface forward, achieving the effect of pushing and gathering oil. Moreover, during the process of the oil-loving roller pushing oil forward, the power unit synchronously drives the oil-loving roller to rotate. The side of the oil-loving roller will adhere to and float the floating oil. As the oil-loving roller rotates, oil-water separation is achieved. Finally, the oil scraper on the outside of the oil-loving roller is scraped off and collected by the oil scraper, so that the rotating oil-loving roller can adhere to and float the floating oil again, ultimately achieving the effect of pushing and gathering oil and adhering and absorbing oil.

Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment equipment, and in particular to a mine water treatment device. Background Technology

[0002] As mining operations continue, the amount of water flowing into the mine is gradually increasing, which undoubtedly brings greater pressure and challenges to mine water treatment. At the same time, grease and oil substances generated during mining operations inevitably mix into the water and enter the water treatment system. These grease and oil substances not only alter the physicochemical properties of the water, affecting the effectiveness of subsequent treatment processes, but may also cause blockages and corrosion in treatment equipment, reducing its service life and operating efficiency.

[0003] Traditional methods for removing surface oil from wastewater primarily rely on the density difference between oil and water. Because oil is less dense than water, when oil and water mix, they separate into layers, with the oil floating on the surface. Based on this characteristic, people typically use straws to suck up the oil or long spoons to skim it off. However, during the oil removal process, the straws or long spoons are difficult to control precisely, easily sucking up the water on top as well. This results in the removed oil containing some water, making the oil-water separation less effective and hindering subsequent oil recycling or further wastewater treatment. Summary of the Invention

[0004] This invention proposes a mine water treatment device that has the advantages of oil pushing and gathering and oil adhesion and absorption, in order to solve the problem mentioned in the background art that traditional oil-water separation is prone to sucking up surface water.

[0005] To achieve the above objectives, this application adopts the following technical solution: a mine water treatment device, comprising: a filter tank, with a support frame movably mounted on the top, and a traveling unit driven by a power unit mounted on the bottom of the support frame; a drive gear, movably mounted on the side of the support frame and connected to the output shaft of the power unit; a transmission gear, movably mounted on the side of the support frame and meshing with the external teeth of the drive gear; an oil-loving roller, coaxially and fastened to the transmission gear; and an oil scraper seat, movably mounted inside the support frame and slidably connected to the side of the oil-loving roller; when the power unit drives the traveling unit to move forward along the top of the filter tank, the support frame drives the oil-loving roller to move forward along the surface of the water layer, thereby achieving the collection of floating oil on the surface of the water layer; the power unit drives the oil-loving roller to rotate via the drive gear and the transmission gear, and the oil-loving roller achieves water-oil separation by adhering to the floating oil; when the oil-loving roller and the oil scraper seat move relative to each other, the oil scraper seat scrapes off the floating oil outside the oil-loving roller.

[0006] Furthermore, there are two transmission gears, which are symmetrically arranged on the side of the support frame.

[0007] Furthermore, the oleophilic roller is a rubber-coated steel roller.

[0008] Furthermore, a collection box is fixedly connected to the bottom of the oil scraper seat.

[0009] Furthermore, a reversing gear rack that meshes with the external teeth of the drive gear is movably installed on the inner side of the support frame, and a guide rod is fixedly installed on the top of the reversing gear rack. One end of the oil scraper seat near the reversing gear rack is movably installed on the guide rod using a bracket, and an oil scraper spring located on the outer side of the guide rod is fixedly installed on the inner side of the reversing gear rack. A magnetic component is fixedly installed on one end of the oil scraper seat, and metal blocks that cooperate with the magnetic component are symmetrically fixedly installed on the side of the support frame.

[0010] Furthermore, there are two scraper springs, located on opposite sides of the scraper seat end.

[0011] Furthermore, as the support frame moves forward, the oil-loving rollers at the front gather and collect the floating oil, while the oil-loving rollers at the rear re-adhere any remaining floating oil.

[0012] Furthermore, guide rods are symmetrically and movably installed at the bottom of the oil scraper seat, and a reversing spring is fixedly connected between the guide rods and the oil scraper seat. Cutting blade assemblies are fixedly installed at both ends of the guide rods, and the two cutting blade assemblies are connected by a transmission component.

[0013] Furthermore, the cutting assembly consists of multiple equally spaced disc cutters.

[0014] The beneficial effects of this invention are as follows:

[0015] This invention provides a mine water treatment device, in which an oil-loving roller is movably mounted on a support frame, and the oil-loving roller is driven by a power unit. During actual operation, when the power unit starts and drives the traveling unit forward, the oil-loving roller moves synchronously above the water surface. The oil-loving roller pushes the floating oil forward in the direction the device is traveling. In this way, the floating oil, originally scattered throughout the water surface, is gradually concentrated together, achieving a significant oil-pushing and converging effect.

[0016] Furthermore, as the oleophilic roller moves forward, the power unit simultaneously drives it to rotate. During rotation, the side of the oleophilic roller comes into contact with the floating oil. Due to the oleophilic and hydrophobic properties of the roller, the floating oil adheres to its surface. As the roller continues to rotate, the floating oil adhering to the surface is carried to the point where it separates from the water, thus achieving initial oil-water separation.

[0017] Finally, when the oleophilic roller rotates to the oil scraper position, the oil scraper will scrape off the floating oil on the outside of the oleophilic roller and collect it. After the oil scraping process, the surface of the oleophilic roller is cleaned and can be put back into the floating oil adhesion work. This cycle is repeated to achieve the effects of pushing and gathering oil and adhering and absorbing oil. Attached Figure Description

[0026] 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.

[0027] Example 1, please refer to Figure 1 and Figure 2 As can be seen, filter tank 1, as a tank containing oil and water, has "T"-shaped guide rails fixedly connected to both sides of its top. A support frame 2 is movably mounted on the top of filter tank 1, and the bottom of the support frame 2 is movably arranged on the guide rails using a traveling unit 4. The traveling unit 4 moves along the guide rails, enabling the support frame 2 to reciprocate horizontally along filter tank 1. A power unit 3 is fixedly mounted on the surface of the support frame 2, and the power unit 3 and the traveling unit 4 are connected by a transmission. More specifically, the power unit 3 is mainly a dual-output shaft motor, with a reducer installed on the motor's output shaft. The traveling unit 4 mainly includes guide wheels, which are connected to the reducer by a belt / chain transmission. This ensures that when the control system adjusts the power unit 3, the power unit 3 drives the traveling unit 4 to move along the guide rails at the top of filter tank 1, thus enabling the support frame 2 to reciprocate horizontally along filter tank 1.

[0028] Combination Figure 6 It can be seen that a drive gear 8 is movably mounted on the side of the support frame 2, and the drive gear 8 is connected to the output shaft of the power unit 3 through a transmission mechanism, including but not limited to belt drive or chain drive. Furthermore, combined with... Figures 3-5 It can be seen that a transmission gear 9 is movably mounted on the side of the support frame 2, meshing with the external teeth of the drive gear 8. In this application, the number of transmission gears 9 is preferably two, and the two transmission gears 9 are symmetrically arranged on the side of the support frame 2. Both transmission gears 9 mesh with the external teeth of the drive gear 8. An oleophilic roller 5 is fixedly mounted on the shaft of each transmission gear 9. The other end of the oleophilic roller 5 is movably connected to the inner side of the support frame 2. The oleophilic roller 5 has oleophilic and hydrophobic properties and is preferably a rubber-coated steel roller. When installed, the oleophilic roller 5 is arranged parallel to the water surface. Generally, the lower part of the roller is immersed in the water surface by 2-5 cm. In this way, when the control system starts the power unit 3, the power unit 3 drives the traveling unit 4 to move, causing the support frame 2 to move forward. At the same time, the oleophilic roller 5 pushes forward along the water surface, causing the floating oil on the water surface to gather together, thereby achieving the purpose of oil gathering.

[0029] Based on this, combined Figures 3-5 It can be seen that an oil scraper seat 7 is movably installed on the inner side of the support frame 2, and the oil scraper seat 7 is slidably connected to the outer wall of the oleophilic roller 5. In this way, when the oleophilic roller 5 picks up floating oil and passes through the oil scraper seat 7, the scraper seat 7 scrapes against the side of the oleophilic roller 5, allowing the floating oil on the outer side of the oleophilic roller 5 to be collected into the oil scraper seat 7. Furthermore, from... Figure 5As can be seen, a collection box 10 is fixedly connected to the bottom of the oil scraper seat 7, and the floating oil flowing into the oil scraper seat 7 is eventually collected and stored in the collection box 10. In actual application, the collection box 10 is connected to an external oil pump through a pipe, and the oil pump can use its suction action to draw the floating oil collected in the collection box 10 outward. A scraper is fixedly installed at the end of the oil scraper seat 7 with bolts. The scraper can scrape oil from the outer side of the oil-loving roller 5, and the detachable scraper facilitates subsequent maintenance and replacement.

[0030] In practical application, the specific work content of this first embodiment is as follows:

[0031] The mine water to be treated is fed into the filter tank 1, and the side of the oleophilic roller 5 is inserted into the surface of the water layer, but the surface of the water layer will not extend beyond the oil scraper seat 7. Figure 4 The state shown.

[0032] As support frame 2 moves forward to the right, the direction reference... Figure 4 At this time, the power unit 3 rotates clockwise and drives the traveling unit 4 to move forward to the right along the guide rail at the top of the filter tank 1. As the support frame 2 drives the oleophilic roller 5 forward, the side of the oleophilic roller 5 moves forward along the surface of the water layer, causing the floating oil on the surface of the water layer to move forward and achieve the purpose of floating oil aggregation.

[0033] Meanwhile, as the support frame 2 moves forward, the power unit 3 drives the drive gear 8 to rotate clockwise synchronously. Driven by the gear transmission, the oleophilic roller 5, located on the right side in the forward direction, rotates counterclockwise. During the rotation of the oleophilic roller 5, its oleophilic and hydrophobic properties are utilized to adhere to the floating oil collected in front of it. As the oleophilic roller 5 continues to rotate counterclockwise, the adhered floating oil rises and detaches from the water surface, achieving water-oil separation. Finally, as the oleophilic roller 5 rotates counterclockwise, the floating oil adhered to its outer side passes the oil scraper 7, which scrapes away the oil from the outer side of the oleophilic roller 5, ultimately collecting it in the collection box 10. The removed oleophilic roller 5 continues to rotate, adhering to the moving floating oil again, thus achieving a continuous oil-adhesion effect.

[0034] Similarly, when the support frame 2 needs to move to the left, the power unit 3 can rotate counterclockwise to achieve the effect of pushing, gathering, adhering, and absorbing oil on the left oil-loving roller 5.

[0035] Example 2 is a further improvement on Example 1. Please refer to Example 1. Figure 4 , Figure 5 and Figure 7It can be seen that the inner side of the support frame 2 has a reversing gear rack 11 that is movably mounted via a dovetail groove. The reversing gear rack 11 can reciprocate horizontally along the side of the support frame 2 using the dovetail groove. The bottom of the reversing gear rack 11 meshes with the external teeth of the drive gear 8. A guide rod is fixedly mounted on the top of the reversing gear rack 11. Correspondingly, one end of the oil scraper seat 7 near the reversing gear rack 11 is movably mounted on the guide rod using a bracket, and an oil scraper spring 12 located on the outer side of the guide rod is fixedly mounted on the inner side of the reversing gear rack 11. From Figure 7 As can be seen, there are two scraper springs 12, located on opposite sides of the end of the scraper seat 7. Furthermore, the end of the scraper seat 7 furthest from the reversing gear 11 is movably mounted on the inner wall of the support frame 2 using a dovetail groove. The scraper seat 7 utilizes a two-end limiting mechanism to achieve horizontal reciprocating movement along the inner wall of the support frame 2. Moreover, combined with… Figure 2 , Figure 4 , Figure 5 and Figure 7 It can be seen that a magnetic component 13 is fixedly installed on one end of the oil scraper seat 7 near the reversing gear row 11. The magnetic component includes, but is not limited to, permanent magnets or electromagnets. Correspondingly, metal blocks are symmetrically fixedly installed on the side of the support frame 2. When the magnetic component 13 on one end of the oil scraper seat 7 approaches the metal block, the magnetic attraction between the magnetic component 13 and the metal block ensures that the oil scraper seat 7 is always in close contact with the outer side of the oil-loving roller 5. On the other hand, the metal block also limits the movement of the magnetic component 13, and the contact strength between the oil scraper seat 7 and the oil-loving roller 5 can be adjusted by adjusting the horizontal installation position of the metal block.

[0036] More specifically, in the application of this second embodiment, in combination with... Figure 4 As shown, taking the support frame 2 moving to the right as an example (the same applies to moving to the left), when the power unit 3 drives the drive gear 8 to rotate clockwise, the right-side oleophilic roller 5 performs the effects of pushing, gathering, and adhering to oil, as described in Example 1. Furthermore, the meshing of the drive gear 8 with the reversing gear 11 forces the reversing gear 11 to move to the right. As the reversing gear 11 moves to the right along the inner wall of the support frame 2, it pushes the scraper spring 12 to move synchronously to the right. Since the bracket on the scraper seat 7 is located between the two scraper springs 12, when the left scraper spring 12 pushes the bracket at the end of the scraper seat 7 to move to the right, the bracket drives the scraper seat 7 to move to the right side of the oleophilic roller 5. At this time, the scraper seat 7 is close to the right-side oleophilic roller 5 and disengages from the left-side oleophilic roller 5. Moreover, when the scraper seat 7 drives the magnetic component 13 close to the right-side metal stop, the magnetic attraction keeps the scraper seat 7 firmly attached to the outer side of the oleophilic roller 5, i.e. Figure 4 The state shown.

[0037] As the drive gear 8 and the reversing gear 11 mesh, the reversing gear 11 continues to move to the right, compressing the spring between the end bracket of the oil scraper seat 7 and the reversing gear 11, until the outer tooth of the left end of the reversing gear 11 moves above the drive gear 8, finally causing the drive gear 8 to disengage from the outer tooth of the left end of the reversing gear 11. During this process, as the drive gear 8 continues to rotate, it will maintain the reversing gear 11's tendency to move to the right. The oil scraping spring 12 on the reversing gear 11 is compressed and subjected to the magnetic attraction between the magnetic component 13 and the metal stop, forcing the oil scraper seat 7 to always adhere to the right-side oil-loving roller 5, thereby completing the scraping of the floating oil outside the right-side oil-loving roller 5.

[0038] Ultimately, it can be seen that as the support frame 2 moves forward to the right, the oil scraper 7 moves closer to the outer side of the right-side oleophilic roller 5, causing the right-side oleophilic roller 5 to adhere to the floating oil accumulated during the forward movement and transport it into the oil scraper 7. Furthermore, because the rightward movement of the oil scraper 7 forces it to move relatively away from the left-side oleophilic roller 5, from... Figure 4 As can be seen, when the support frame 2 moves forward to the right, the drive gear 8 synchronously drives the left-side oleophilic roller 5 to rotate counterclockwise. Combined with the horizontal arrangement between the two oleophilic rollers 5, when the support frame 2 moves forward, the front oleophilic roller 5 can adhere to and collect the accumulated floating oil. As the left / rear oleophilic roller 5 moves to the right, it can also adhere to and collect the floating oil that is missed by the right / front oleophilic roller 5. This ensures that the support frame 2 can achieve the purpose of secondary adhesion of floating oil when it moves to the right as a whole, thereby avoiding the problem of floating oil leakage when the support frame 2 moves forward.

[0039] Similarly, when the support frame 2 moves to the left, the oil scraper 7 also moves to the left and attaches to the oil-loving roller 5 on the left. It then approaches the metal block on the left through the magnetic component 13, so that the oil-loving roller 5 moving forward on the left collects the floating oil, and the oil-loving roller 5 on the right re-adheres any missed floating oil.

[0040] Example 3 is a further improvement on Example 2. During water treatment, large particles of scum or other impurities may appear in the water, blocking the oleophilic roller 5 or wrapping around its outer side, which can easily lead to a decrease in the oleophilic ability of the oleophilic roller 5. This Example 3, based on Example 2, combines... Figure 3 , Figure 4 and Figure 7 It can be seen that guide rods 601 are symmetrically and movably installed at the bottom of the oil scraper seat 7, and a reversing spring 602 is fixedly connected between the guide rod 601 and the oil scraper seat 7, sleeved on the outer side of the guide rod 601. One end of the reversing spring 602 is fixedly connected to the oil scraper seat 7, and the other end is fixedly connected to the guide rod 601. Furthermore, a rubber protective sleeve is provided between the oil scraper seat 7 and the guide rod 601 to protect the reversing spring 602.

[0041] from Figure 7 As can be seen, cutter assemblies 6 are fixedly installed at both ends of the guide rod 601. Each cutter assembly 6 consists of multiple equally spaced disc cutters. A top dirt block is placed on the cutter assembly 6 support and between the cutters to ensure that impurities between the cutter assemblies 6 are cleaned out when the cutter assemblies 6 rotate. Furthermore, the two cutter assemblies 6 are connected by a transmission assembly 603, preferably a chain drive, which generally requires protective wrapping.

[0042] In practical application, the specific work content of this third embodiment is as follows:

[0043] by Figure 4 For example, when the support frame 2 moves to the right, the movement of the oil scraper 7 and the oil collection of the oil-loving roller 5 are the same as described above.

[0044] Under normal conditions, the reversing spring 602 is in a freely extended state. As the oil scraper 7 moves to the right, it pushes the guide rod 601 to the right via the reversing spring 602. When the guide rod 601 moves to the right, the left-side cutter assembly 6 comes into contact with the side of the left-side oleophilic roller 5, while the right-side cutter assembly 6 moves relatively away from the right-side oleophilic roller 5. After the left-side cutter assembly 6 contacts the outer side of the left-side oleophilic roller 5, the continuing rightward movement of the oil scraper 7 compresses the reversing spring 602 until the oil scraper 7 contacts the side of the right-side oleophilic roller 5. During this process, the counter-clockwise rotation of the oleophilic roller 5 achieves the effects of pushing oil and adhering floating oil. Furthermore, since there is a certain gap between the right-side cutter group 6 and the right-side oleophilic roller 5, the outer side of the cutter group 6 normally extends above the water surface. When the support frame 2 moves to the right, the cutter group 6 on the right side uses the gap between the cutters to perform coarse filtration of the water, so that the scum on the surface of the water layer is relatively far away from the right-side oleophilic roller 5, reducing the impact of scum on the adhesion of floating oil to the right-side oleophilic roller 5.

[0045] Meanwhile, since the left-side cutter assembly 6 is in close contact with the outer side of the left-side oleophilic roller 5, when the left-side oleophilic roller 5 rotates counterclockwise, it can drive the cutter assembly 6 to rotate clockwise synchronously. During the rotation, the cutter assembly 6, which is in contact with the outside of the oleophilic roller 5, can cut the wrapped material relatively. Furthermore, when the cutter assembly 6 rotates clockwise, the transmission component 603 drives the right-side forward cutter assembly 6 to rotate synchronously. The clockwise rotation of the right-side cutter assembly 6 can move the float obstructing the cutter assembly 6, ensuring that the floating oil can pass through the cutter assembly 6 normally.

[0046] Ultimately, it can be seen that by using the method described in this embodiment 3, the floating blocks can be coarsely intercepted by the cutter group 6 in the forward direction during the forward movement of the support frame 2. By using the close proximity between the rear cutter group 6 and the oleophilic roller 5, not only is the wrapped material on the oleophilic roller 5 cut off, but the cutter group 6 in the forward direction can also be rotated to transfer the floating blocks accumulated in front of the cutter group 6.

[0047] If the support frame 2 needs to move to the left, similarly, the right-side cutter assembly 6 eventually attaches to the side of the right-side oleophilic roller 5, and the scraper seat 7 moves to the left and attaches to the outside of the left-side oleophilic roller 5. The scraper seat 7 and the guide rod 601 achieve the traction and elongation of the reversing spring 602. Ultimately, the left-side cutter assembly 6 performs coarse filtration, and the right-side cutter assembly 6 cuts off the wrapped material from the outside of the right-side oleophilic roller 5.

[0048] As a supplement to Embodiment 3, in practical applications, a protective wire mesh is typically installed at the bottom of the support frame 2 to prevent scum from moving directly from below the support frame 2 towards the oleophilic roller 5. The blocking properties of the wire mesh further reduce direct contact between the oleophilic roller 5 and large pieces of scum.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
