Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, specifically a low-suspended-solids oily mine water treatment device for coal mines. Background Technology

[0002] Mine water is water formed during coal mining. During coal mining, groundwater comes into contact with coal seams and rock strata, and with the influence of human activities, a series of physical, chemical and biochemical reactions occur. Mine water contains suspended solids, and the suspended solids content is much higher than that of surface water. Moreover, the suspended solids contained in mine water are small in size, light in specific gravity, slow in settling speed, and have poor coagulation effect. Mine water also contains organic pollutants such as waste engine oil and emulsified oil.

[0003] In the treatment of low-suspended-solids oily mine water, the oil floating on the surface of the mine water is scraped off by the treatment equipment. However, existing treatment equipment uses oil-absorbing cotton boards that move on the surface of the mine water to absorb the oil. However, during operation, the oil-absorbing cotton boards are easily saturated and cannot be used, resulting in frequent replacement of the oil-absorbing cotton boards, which is not conducive to improving the oil absorption and treatment efficiency of the mine water. In view of the above-mentioned technical defects of the existing technology, this paper provides a low-suspended-solids oily mine water treatment equipment for coal mines to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a low-suspended-solids oily mine water treatment device for coal mines, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A low-suspended-solids oily mine water treatment device for coal mines includes a wastewater tank with a discharge pipe installed on it. A translation frame is slidably installed on the wastewater tank, and a rotating frame is rotatably installed on the translation frame. A portal frame is vertically slidably installed on the rotating frame, and a rotating roller is rotatably installed at the lower end of the portal frame. Several oil-absorbing cotton plates are evenly arranged circumferentially on the rotating roller. A column is fixed on the rotating frame and vertically slidably connected to the portal frame. An adjusting sleeve is threaded onto the column, and the lower end of the adjusting sleeve abuts against the portal frame. A threaded rod is rotatably installed on the wastewater tank and threadedly connected to the translation frame. A rotating gear is coaxially fixed on the rotating roller. A rack is connected to the wastewater tank via a vertical elastic component, and the rack meshes with the rotating gear.

[0007] As an improvement of the present invention: the vertical elastic component includes a plurality of vertical springs fixed to the bottom of the rack, the lower end of the vertical springs being fixed to the wastewater tank, and the rack being vertically slidably connected to the wastewater tank.

[0008] As an improvement of the present invention: a spring ring is sleeved on the column, and the two ends of the spring ring are fixedly connected to the adjusting sleeve block and the rotating frame, respectively.

[0009] As an improvement of the present invention: a motor I and a transmission box are fixed on the wastewater tank, the threaded rod extends into the transmission box, and a transmission assembly for driving the threaded rod to rotate alternately clockwise and counterclockwise is provided in the transmission box.

[0010] As an improvement of the present invention: the transmission assembly includes driven bevel gear I and driven bevel gear II, which are coaxially fixed with the threaded rod, and the output shaft of the motor I has an incomplete bevel gear that alternately meshes with the driven bevel gear I and driven bevel gear II.

[0011] As an improvement of the present invention: a cover plate is fixed on the gantry frame and placed on the rotating roller, and an arc-shaped oil-absorbing cotton plate that contacts the oil-absorbing cotton plate is fixed on the inner wall of the cover plate.

[0012] As an improvement of the present invention: a sliding plate is fixed on the oil-absorbing cotton plate, the sliding plate is slidably mounted on the rotating roller, and a radial spring is fixed between the sliding plate and the rotating roller.

[0013] As an improvement of the present invention: a motor II is fixed on the translation frame, a worm gear is coaxially fixed on the output shaft of the motor II, a worm wheel is meshed on the worm gear, a rotating shaft is coaxially fixed on the worm wheel, and the rotating shaft is fixed to the rotating frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This device uses a threaded rod that rotates clockwise alternately to drive the translation frame and its rotating roller to move laterally relative to the wastewater tank. Meanwhile, a rotating gear meshes with a rack and pinion to rotate the roller and its attached oil-absorbing cotton plates, absorbing the oil floating on the surface of the wastewater tank. Multiple oil-absorbing cotton plates can alternately absorb the oil, greatly improving the absorption effect and avoiding frequent replacements. During rotation, the oil-absorbing cotton plates sequentially contact and slide against the curved oil-absorbing cotton plates, ensuring the curved plates effectively absorb the oil adhering to them, significantly enhancing the device's oil absorption efficiency.

Detailed Implementation

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments:

[0023] Example 1

[0024] Please see Figure 1-5 A low-suspended-solids oily mine water treatment device for coal mines includes a wastewater tank 1, a discharge pipe 2 installed on the wastewater tank 1, a sliding frame 4 slidably installed on the wastewater tank 1, a rotating frame 8 rotatably installed on the sliding frame 4, a portal frame 9 vertically slidingly installed on the rotating frame 8, a rotating roller 16 rotatably installed at the lower end of the portal frame 9, a plurality of oil-absorbing cotton plates 17 evenly arranged circumferentially on the rotating roller 16, a column 10 fixed on the rotating frame 8 and vertically slidingly connected to the portal frame 9, a spring ring 11 sleeved on the column 10, and the two ends of the spring ring 11 being fixedly connected to the adjusting sleeve block 19 and the rotating frame 8 respectively. An adjusting sleeve 19 is threaded onto the column 10, and the lower end of the adjusting sleeve 19 abuts against the gantry frame 9. A threaded rod 3 that is threadedly connected to the translation frame 4 is rotatably installed on the wastewater tank 1. A rotating gear 20 is coaxially fixed on the roller 16. A rack 18 is connected and installed on the wastewater tank 1 through a vertical elastic component, and the rack 18 meshes with the rotating gear 20.

[0025] Low-suspended-solids oily mine water is placed in wastewater tank 1 and linearly slids relative to wastewater tank 1 through translation frame 4 to move the position of rotating roller 16. At the same time, the rotating gear 20 and rack 18 are meshed and connected. The rotating gear 20 rotates and drives the rotating roller 16 to rotate. At this time, the oil-absorbing cotton plate 17 can rotate and scrape and absorb the oil floating on the surface of the mine water.

[0026] By turning the adjusting sleeve 19, it can be moved vertically relative to the column 10, so that the gantry frame 9 can be moved vertically relative to the rotating frame 8. That is, the vertical height of the rotating roller 16 can be adjusted, so that the oil-absorbing cotton plate 17 can be moved vertically to contact the surface of the mine water, ensuring that the oil stains are effectively absorbed when the oil-absorbing cotton plate 17 rotates.

[0027] The vertical elastic component of this device includes several vertical springs 23 fixed to the bottom of the rack 18. The lower end of the vertical springs 23 is fixed to the wastewater tank 1, and the rack 18 is vertically slidably connected to the wastewater tank 1.

[0028] During the vertical height adjustment of the roller 16, the rotating gear 20 can move vertically. Under the elastic action of the vertical spring 23, the rack 18 can slide vertically relative to the wastewater tank 1 and maintain meshing with the rotating gear 20, so that the roller 16 can maintain rotation while moving linearly.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, in addition, a motor I6 and a transmission box 5 are fixed on the wastewater tank 1 of this device. The threaded rod 3 extends into the transmission box 5, and a transmission assembly for driving the threaded rod 3 to rotate alternately clockwise and counterclockwise is provided inside the transmission box 5. The transmission assembly includes a driven bevel gear I24 and a driven bevel gear II25 that are coaxially fixed with the threaded rod 3. An incomplete bevel gear 26 is coaxially connected to the output shaft of the motor I6 and alternately meshes with the driven bevel gear I24 and the driven bevel gear II25.

[0031] With the above settings, motor I6 can drive the incomplete bevel gear 26 to rotate. The incomplete bevel gear 26 alternately meshes with driven bevel gear I24 and driven bevel gear II25, so that the threaded rod 3 can rotate clockwise and counterclockwise alternately under the driving action of driven bevel gear I24 and driven bevel gear II25. At this time, the translation frame 4 can automatically perform linear reciprocating motion, that is, the oil-absorbing cotton plate 17 can automatically perform linear reciprocating motion, which greatly improves the oil absorption efficiency of mine water.

[0032] In addition, a cover plate 7 is fixed on the gantry frame 9 and covers the rotating roller 16. An arc-shaped oil-absorbing cotton plate 27 that contacts the oil-absorbing cotton plate 17 is fixed on the inner wall of the cover plate 7. A sliding plate 21 is fixed on the oil-absorbing cotton plate 17. The sliding plate 21 is slidably mounted on the rotating roller 16. A radial spring 22 is fixed between the sliding plate 21 and the rotating roller 16.

[0033] When the rotating roller 16 rotates, it drives the sliding plate 21 to rotate, thereby rotating the oil-absorbing cotton plate 17. During the rotation, the oil-absorbing cotton plate 17 slides into contact with the arc-shaped oil-absorbing cotton plate 27, so that the oil-absorbing cotton plate 17 contacts the arc-shaped oil-absorbing cotton plate 27 once after scraping off the oil stains. The arc-shaped oil-absorbing cotton plate 27 absorbs the oil stains on the oil-absorbing cotton plate 17 once, which greatly promotes the absorption effect of the oil-absorbing cotton plate 17 on the mine water oil stains and avoids it from becoming saturated too quickly.

[0034] Additionally, a motor II14 is fixed to the translation frame 4. A worm gear 13 is coaxially fixed to the output shaft of the motor II14. A worm wheel 15 is meshed with the worm gear 13. A rotating shaft 12 is coaxially fixed to the worm wheel 15, and the rotating shaft 12 is fixed to the rotating frame 8. By starting the motor II14, it can drive the worm gear 13 to rotate, which in turn drives the worm wheel 15 to rotate. This allows the worm wheel 15 to drive the rotating frame 8 to rotate 180 degrees, ensuring that the arc-shaped oil-absorbing cotton plate 27 is vertically upward, facilitating regular cleaning or replacement of the arc-shaped oil-absorbing cotton plate 27 and the oil-absorbing cotton plate 17.

[0035] In summary, this device uses the clockwise alternating rotation of the threaded rod 3 to drive the translation frame 4 and the rotating roller 16 on it to move laterally relative to the wastewater tank 1. The rotating gear 20 meshes with the rack 18 to drive the rotating roller 16 and the oil-absorbing cotton plate 17 on it to rotate and absorb the oil floating on the surface of the wastewater tank 1. Multiple oil-absorbing cotton plates 17 can absorb the oil alternately, which greatly improves the oil absorption effect and avoids frequent replacement of oil-absorbing cotton plates 17. During the rotation of the oil-absorbing cotton plate 17, it successively abuts and slides against the arc-shaped oil-absorbing cotton plate 27, so that the arc-shaped oil-absorbing cotton plate 27 can have a good absorption effect on the oil adhering to the oil-absorbing cotton plate 17, which greatly improves the oil absorption effect of this device.
