Description

Technical Field

[0001] This invention relates to the field of mine water treatment technology, and in particular to a segmented ceramic ultrafiltration treatment device and method for mine water reuse. Background Technology

[0002] Mine water is a mixed wastewater generated during the mining process. It contains high concentrations of suspended solids, heavy metal ions, high-hardness calcium and magnesium salts, and a small amount of organic matter. Direct discharge will pollute the soil and groundwater. Mine water reuse is the key to "water conservation and emission reduction". It is used in conjunction with ceramic ultrafiltration devices to filter the wastewater.

[0003] In order to ensure treatment efficiency and meet the needs of large-scale wastewater treatment, existing ceramic ultrafiltration devices are generally equipped with multiple filter elements. Then, a water distribution method is used to flow wastewater into each filter element. However, this design makes it difficult to distribute wastewater evenly. During the initial start-up phase of the device, some elements may contain water while others are dry, which greatly increases the pressure fluctuation range inside the device and the probability of the device automatically triggering shutdown protection. This not only affects the continuity of operation, but also causes secondary damage to the core electrical equipment due to frequent start-ups and shutdowns. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0016] A method for a segmented ceramic ultrafiltration treatment device for mine water reuse includes the following steps:

[0017] Step 1: Control the centrifugal pump to inject the mine return water into the distribution component.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a segmented ceramic ultrafiltration treatment device for mine water recycling. The segmented ceramic ultrafiltration treatment device for mine water recycling includes a treatment component 1, a distribution component 2, an adjustment component 3, a drainage component 4, and an air storage component 5. By setting the adjustment component 3, the drainage component 4, and the air storage component 5, the transmission space can be dynamically adjusted according to the injected water flow rate, further stabilizing the liquid transmission pressure. When the compressed gas is backflushing for cleaning, the drainage operation is completed simultaneously, eliminating the need for manual operation, simplifying the operation steps, and improving the overall work efficiency.

[0039] Specifically, the processing component 1 includes a centrifugal pump 11, a ceramic ultrafiltration cartridge 12 is provided on one side of the centrifugal pump 11, a transfer tube 13 is fixed on the ceramic ultrafiltration cartridge 12, and a liquid pump 14 is connected to one end of the transfer tube 13.

[0040] The ceramic ultrafiltration cartridge 12 has a multi-layer asymmetric structure, which is usually divided into a core functional layer and an auxiliary structure from the inside out.

[0041] The ceramic ultrafiltration cartridge 12 includes a support layer, which is usually made of high-temperature and high-strength ceramic materials such as alumina, silicon carbide, and cordierite. It has a large pore size and high porosity. Its main function is to withstand the pressure during the filtration process, prevent the filter element from deforming or breaking, and at the same time provide stable support for subsequent stages to ensure smooth flow of fluid during filtration.

[0042] The ceramic ultrafiltration cartridge 12 also includes a transition layer: ultrafine ceramic powder compatible with the support layer is selected, with a pore size between the support layer and the separation layer. Its function is to refine the pore size, smooth the surface of the support layer, avoid damage to the separation layer caused by the large pores of the support layer, reduce the difficulty of preparing the separation layer, improve the bonding strength between the separation layer and the support layer, and prevent the separation layer from falling off.

[0043] The ceramic ultrafiltration cartridge 12 also includes a separation layer: it is a special ceramic of zirconium oxide or alumina with a small pore size. This layer accurately intercepts target substances in the fluid through pore size sieving. It is the key part that determines the ultrafiltration accuracy and separation effect. Its surface is smooth and the pores are uniform, which can reduce the adhesion of pollutants while intercepting impurities.

[0044] In summary, the ceramic ultrafiltration cartridge 12, relying on the nanoscale pore size of the separation layer, can efficiently trap impurities such as suspended solids, colloids, bacteria, and large organic molecules in the fluid, while allowing water, small molecule solvents, or small molecule solutes to pass through. It is well-suited for the needs of mine water reuse treatment. The working principle of this part is all existing technology, which can be clearly understood by those skilled in the art, and will not be elaborated here.

[0045] The transmission tube 13 serves as a transition, connecting the upper-level distribution component 2 and the lower-level distribution component 2 to complete segmented processing, which better meets actual usage requirements.

[0046] The liquid pump 14 is responsible for extracting and transporting the purified water (clear water that meets the reuse standard) treated by the ceramic ultrafiltration cartridge 12 to the subsequent reuse system (such as mine production reuse, water storage facilities). The centrifugal pump 11 provides inlet water pressure, and the liquid pump 14 can reduce the pressure on the product water side by extracting the product water, further expanding the transmembrane pressure difference, thereby improving the filtration speed and product water efficiency.

[0047] Specifically, the distribution component 2 is located at the bottom of the ceramic ultrafiltration cartridge 12, including a transmission cylinder 21 fixed on the ceramic ultrafiltration cartridge 12, and a distribution tube 22 fixed inside the transmission cylinder 21.

[0048] Both ends of the transmission cylinder 21 are fixed with flanges, and both ends of the distribution pipe 22 are also fixed to the flanges. That is, the water introduced through the transmission cylinder 21 will first enter the distribution pipe 22. The flange design allows the two transmission cylinders 21 to be combined and installed with bolts to meet the needs of large-scale processing.

[0049] Specifically, the adjustment component 3 is set in the distribution component 2, including an integrated head 31 fixed in the transmission tube 21, a branch pipe 311 fixed at the bottom of the integrated head 31, a vertical rod 32 slidably connected in the integrated head 31, a positioning plate 321 fixed at the bottom of the vertical rod 32, a first sealing seat 323 fixed at the top of the vertical rod 32, a fixed shell 33 fixed in the integrated head 31, a slot 331 opened on the fixed shell 33, and an adjustment component 34 set in the fixed shell 33.

[0050] By integrating the head 31 and branch pipes 311, multiple branch pipes 311 can be evenly distributed within the transfer cylinder 21, thereby uniformly drawing liquid from the transfer cylinder 21 and reducing the impact of pressure fluctuations caused by uneven extraction.

[0051] Specifically, the drainage component 4 is installed inside the distribution pipe 22, including a buoyancy member 41 that passes through the distribution pipe 22, a sleeve 42 that is installed outside the buoyancy member 41, an overflow hole 421 that is opened on the outer ring of the sleeve 42, a transmission sleeve 43 that is fixed at the bottom inside the distribution pipe 22, a support member 44 that is installed inside the transmission sleeve 43, and a trigger member 45 that is installed at the top of the support member 44.

[0052] The overflow hole 421 allows liquid to be transferred into the distribution pipe 22 while the centrifugal pump 11 is in operation. Finally, the liquid is transferred outward to the transmission cylinder 21 through multiple overflow holes 421, causing the overall liquid level in the transmission cylinder 21 to rise and submerge multiple branch pipes 311 for water transmission through the branch pipes 311.

[0053] Specifically, the air storage component 5 is installed on the transmission cylinder 21, including an air storage cylinder 51 fixed on the transmission cylinder 21, an air intake solenoid valve 52 fixed at the air inlet end of the air storage cylinder 51, and an exhaust solenoid valve 53 fixed at the air outlet end of the air storage cylinder 51.

[0054] The end of the bleed solenoid valve 52 away from the gas storage tank 51 is connected to an external compressed gas source. That is, when the bleed solenoid valve 52 is open, the compressed gas automatically enters the gas storage tank 51 through the bleed solenoid valve 52, while the exhaust solenoid valve 53, when open, can release the compressed gas stored in the gas storage tank 51.

[0055] Example 2, refer to Figures 2-12 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0056] Specifically, a bracket 15 is provided between the centrifugal pump 11 and the liquid pump 14, and the ceramic ultrafiltration cartridge 12, the transfer tube 13 and the transfer tube 21 are all fixed on the bracket 15.

[0057] The bracket 15 provides installation positions for the transfer cylinder 21, ceramic ultrafiltration cylinder 12 and transfer pipe 13, making reasonable use of the working space and ensuring the overall compactness of the device.

[0058] Specifically, the top of the transmission tube 21 is provided with an infusion head 23, and a connector 35 is fixed to the top of the infusion head 23. The outer ring of the integrated head 31 is fixed inside the infusion head 23. The connection between the vertical rod 32 and the integrated head 31 is sealed. A first spring 322 is sleeved on the vertical rod 32. The bottom end of the first spring 322 is fixed to the positioning plate 321, and the top end of the first spring 322 is fixed to the bottom of the integrated head 31. A sealing groove 351 is provided inside the connector 35 and cooperates with the first sealing seat 323. An arc-shaped groove 324 is provided on the outer ring of the vertical rod 32.

[0059] As shown in the attached diagram of the instruction manual. Figure 8 and Figure 9 As shown, in this state, water can flow through the gap between the first sealing seat 323 and the sealing groove 351. As the first sealing seat 323 moves upward, the gap between the first sealing seat 323 and the sealing groove 351 gradually increases, increasing the space available for water flow. When the first sealing seat 323 gradually moves downward, it will come into contact with the sealing groove 351, and the two work together to achieve a sealing effect.

[0060] Specifically, the adjusting component 34 includes a rotating ring 341 rotatably connected to the fixed housing 33. The inner ring of the rotating ring 341 is fitted with a steel ball 3411 with a clearance and slides in contact with the arc-shaped groove 324. An auxiliary seat 342 is fixed to the top of the rotating ring 341. A baffle 343 is rotatably connected to the auxiliary seat 342. A torsion spring 3421 is sleeved on the auxiliary seat 342. One end of the torsion spring 3421 is fixed to the baffle 343, and the other end of the torsion spring 3421 is fixed to the auxiliary seat 342. The baffle 343 cooperates with the empty groove 331, and the size of the baffle 343 is larger than the size of the empty groove 331.

[0061] By cooperating with the steel ball 3411 and the arc groove 324, the angle of the steel ball 3411 can be changed when the vertical rod 32 is linearly displaced, thereby adjusting the angle of the rotating ring 341 and thus adjusting the overlapping area of ​​the baffle 343 and the empty groove 331.

[0062] The torsion spring 3421 can provide torque to the baffle 343, so that the baffle 343 fits well with the fixed shell 33 without external force, thus preventing the baffle 343 from rotating and opening at will.

[0063] Specifically, the buoyancy component 41 includes a counterweight rod 411 slidably connected to the sleeve 42, a second sealing seat 412 fixed at the bottom of the counterweight rod 411, the second sealing seat 412 slidably connected to the sleeve 42, and a float 413 fixed at the top of the counterweight rod 411, the float 413 being located directly below the positioning disk 321.

[0064] When the float 413 moves upward, it can push the positioning plate 321 upward. The connection between the counterweight rod 411 and the sleeve 42 is sealed.

[0065] The second sealing seat 412 can contact the sleeve 42 to provide a sealing and protection function. When the second sealing seat 412 is located at the overflow hole 421 and blocks the overflow hole 421, water can be prevented from flowing out through the sleeve 42 and the overflow hole 421.

[0066] Specifically, the support member 44 includes a fixing frame 441 fixed to the bottom of the transmission sleeve 43, a first electrode plate 4411 fixed to the top of the fixing frame 441, a second spring 4412 sleeved on the fixing frame 441, and the bottom of the second spring 4412 fixed to the fixing frame 441.

[0067] Specifically, the trigger 45 includes an auxiliary rod 451 located inside the transmission sleeve 43. The auxiliary rod 451 has a storage groove 4511 and slides in contact with the fixing frame 441. A second electrode plate 4512 and a third electrode plate 4513 are fixed in the storage groove 4511 respectively. The third electrode plate 4513 is located at the bottom of the second electrode plate 4512. A third sealing seat 452 is slidably connected to the auxiliary rod 451. A third spring 4514 is fixed at the top of the third sealing seat 452. The top of the third spring 4514 is fixed to the auxiliary rod 451.

[0068] Specifically, a protruding sleeve 453 is fixed at the bottom of the outer ring of the auxiliary rod 451. A diagonal strip 454 is rotatably connected to the protruding sleeve 453. A locking block 455 is rotatably connected to the other end of the diagonal strip 454. The end of the locking block 455 away from the diagonal strip 454 passes through the third sealing seat 452 and slides in contact with the third sealing seat 452. A slot 431 is opened on the inner wall of the transmission sleeve 43 and cooperates with the locking block 455.

[0069] The top of the second spring 4412 is fixed to the bottom of the third sealing seat 452.

[0070] The storage slot 4511 and the fixing bracket 441 can play a positioning and guiding role, ensuring the stability of the vertical displacement of the auxiliary rod 451.

[0071] As shown in the attached diagram of the instruction manual. Figure 12 As shown, the inner cavity of the transmission sleeve 43 consists of a small diameter, a frustum diameter, and a large diameter from top to bottom. The fixing bracket 441 is fixed in the large diameter. When the locking block 455 is inserted into the locking groove 431, the third sealing seat 452 is slidably connected in the small diameter to achieve sealing protection. When the third sealing seat 452 moves down into the frustum diameter, the third sealing seat 452 no longer makes sealing contact with the inner wall of the transmission sleeve 43.

[0072] When the auxiliary rod 451 is pressed down by the second sealing seat 412, the third sealing seat 452 will not move down because the locking block 455 is locked into the locking groove 431. As the auxiliary rod 451 moves, it drives the protrusion 453 to move down. With the connection of the inclined bar 454, the locking block 455 gradually disengages from the locking groove 431, and the third spring 4514 is compressed. After the locking block 455 is completely disengaged from the locking groove 431, the third sealing seat 452 will also move down with the auxiliary rod 451 with the connection of the third spring 4514, and the second spring 4412 will be compressed.

[0073] Similarly, when the second sealing seat 412 no longer presses against the auxiliary rod 451, under the elastic support of the second spring 4412, the third sealing seat 452 and the auxiliary rod 451 are automatically driven to move upward and reset. Under the elastic connection of the third electrode plate 4513, the locking block 455 is always in contact with and slides against the inner wall of the transmission sleeve 43 during the upward movement. After the locking block 455 is aligned with the slot 431, under the elastic connection of the third electrode plate 4513, the locking block 455 is automatically inserted into the slot 431. In this state, even if there is a high-speed water flow in the distribution pipe 22, it cannot squeeze the third sealing seat 452 downward, thus ensuring the sealing effect.

[0074] Example 3, referring to Figures 2-12 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0075] As shown in the attached diagram of the instruction manual. Figure 11As shown, the upper end of the auxiliary rod 451 is rectangular and is set at a 45-degree angle inside the distribution pipe 22. With this design, when the water flows in the distribution pipe 22, it will be divided by the tip of the auxiliary rod 451. Compared with the traditional straight side placement, it can avoid the water flow continuously impacting the auxiliary rod 451 and generating a large force, which would cause the auxiliary rod 451 to quickly fatigue and be damaged.

[0076] The third sealing seat 452 includes an auxiliary block slidably connected to the auxiliary rod 451, a sealing sleeve fixed to the outer ring of the auxiliary block, and a convex ring fixed to the bottom of the auxiliary block. The sealing sleeve slides in contact with the inner wall of the transmission sleeve 43, which can play a sealing and protective role to prevent water leakage. One end of the locking block 455 passes through the convex ring and slides in contact with the convex ring. The two work together to play a guiding role and ensure the lateral displacement stability of the locking block 455.

[0077] As shown in the attached diagram of the instruction manual. Figure 12 As shown, a limiting block is fixed on the inner wall of the transmission sleeve 43 and above the third sealing seat 452 to prevent the third sealing seat 452 from moving excessively upward.

[0078] As shown in the attached diagram of the instruction manual. Figure 5 As shown, the bottom of the inner cavity of the transmission cylinder 21 is designed with a central depression, which can concentrate the water in the transmission cylinder 21 at the center during the drainage stage.

[0079] A method for a segmented ceramic ultrafiltration treatment device for mine water reuse includes the following steps:

[0080] First, the centrifugal pump 11 is controlled to inject mine wastewater into the first-stage distribution component 2. The ceramic ultrafiltration cartridge 12 is gradually filled with water and filtration is completed. Under the guidance of the transmission pipe 13, the water continues to be transmitted into the second-stage distribution component 2, where the new ceramic ultrafiltration cartridge 12 completes the secondary filtration. Simultaneously, the liquid pump 14 is controlled to actively pump water, maintaining the water injection and pumping rates at the same rate, thus achieving segmented treatment.

[0081] During the above process, as the wastewater enters the distribution pipe 22, due to the initial sealing setting of the second sealing seat 412 and the sleeve 42, the water will automatically squeeze the second sealing seat 412 upward until the overflow hole 421 is exposed. The wastewater enters the transmission cylinder 21, and the liquid level in the transmission cylinder 21 gradually rises. The wastewater covers the branch pipe 311. Due to the operation of the liquid pump 14, the wastewater in the transmission cylinder 21 will enter the ceramic ultrafiltration cylinder 12 through the branch pipe 311, the integrated head 31, the empty tank 331 and the connector 35. The float ball 413 moves further upward under the action of buoyancy, contacts and presses against the positioning plate 321, and the first spring 322 is compressed.

[0082] Due to process limitations, the water injection speed of centrifugal pump 11 and the water pumping speed of liquid pump 14 will change dynamically, which will cause the liquid level in the transmission cylinder 21 to change. Taking the liquid level rising as an example, it means that the water injection speed is greater than the water pumping speed. The float 413 moves upward accordingly, further squeezing the vertical rod 32 to move upward. With the cooperation of steel ball 3411 and auxiliary seat 342, the rotating ring 341 rotates, thereby adjusting the overlap area between baffle 343 and empty tank 331 to reduce the flow rate and stabilize the liquid pressure transmitted through connector 35. Similarly, when the liquid level drops, the overlap area between baffle 343 and empty tank 331 increases, increasing the flow rate and stabilizing the pressure transmitted through connector 35.

[0083] When the filtration process is complete, the centrifugal pump 11 stops working first, while the liquid pump 14 stops working later, so that the liquid level in the transfer cylinder 21 is at a low level, the float 413 is no longer supported by buoyancy, and with the cooperation of the counterweight rod 411, the second sealing seat 412 actively moves down to seal the overflow hole 421 until the liquid level in the transfer cylinder 21 is lower than the horizontal plane at the bottom of the branch pipe 311.

[0084] When backflushing cleaning is required, compressed gas is reversed and introduced into the ceramic ultrafiltration cartridge 12, first providing downward thrust to the first sealing seat 323 until the first sealing seat 323 and the sealing groove 351 are in contact to complete the seal. During this process, the vertical rod 32 moves down synchronously, the positioning plate 321 moves down to actively squeeze the float 413 to move down, and the second sealing seat 412 squeezes the auxiliary rod 451 to move down until the third electrode plate 4513 cooperates with the first electrode plate 4411, so that the air intake solenoid valve 52 opens and compressed air enters the air storage cylinder 51.

[0085] As the auxiliary rod 451 moves down, the locking block 455 disengages from the locking slot 431, and then the third sealing seat 452 moves down accordingly. The residual water in the transmission cylinder 21 is discharged through the overflow hole 421, the distribution pipe 22, and the transmission sleeve 43. At the same time, when the third electrode plate 4513 is no longer in contact with the first electrode plate 4411 and the second electrode plate 4512 is in contact with the first electrode plate 4411, the exhaust solenoid valve 53 automatically opens, and compressed air is introduced into the transmission cylinder 21, which not only accelerates the discharge of water but also achieves backflushing cleaning of the distribution pipe 22 after the water is discharged.
