Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sulfide adsorption device for treating mine wastewater pollution. Background Technology

[0002] Sulfide adsorption devices for mine wastewater pollution treatment are mainly used to remove sulfides from mine wastewater, reducing wastewater pollution to the environment and protecting ecological balance and human health. Wastewater generated during mining and processing typically contains large amounts of sulfides. Direct discharge without effective treatment can lead to serious consequences such as water body deterioration and soil pollution. Current devices in practical applications generally require the following technologies:

[0003] 1. Adsorbent material, capable of rapidly and in large quantities adsorbing sulfides;

[0004] 2. Control and monitoring system to monitor the adsorption process and wastewater treatment effect in real time;

[0005] 3. Anti-corrosion measures to address the corrosiveness of wastewater.

[0006] Currently, various equipment and methods are used to adsorb sulfides in mine wastewater.

[0007] For example, a Chinese patent discloses an industrial sulfide wastewater treatment device (patent number: CN221166336U). This device filters large particles of impurities from the wastewater using a filter screen. The filtered wastewater then enters a sedimentation box. After sedimentation, a second pump is turned on, using the first water pipe to draw the upper layer of water from the sedimentation box into activated carbon. After further filtration of harmful impurities, the water leaks out through a drain hole. The threaded rod is then rotated to discharge the settled wastewater. The first pump is then turned on again, using the second water pipe to pump the filtered water back into the sedimentation box for sedimentation. This process is repeated until the treated water is discharged through the drain pipe after the valve is opened. The threaded rod is then rotated again to discharge the settled wastewater, thus enabling the device to achieve a circulating wastewater filtration effect.

[0008] However, the above method has a prominent problem: the device uses a filter box containing activated carbon to adsorb and purify sulfides, but the filter box is placed relatively fixed and lacks a flipping mechanism. The filter media needs to be replaced after a long period of use. The lack of a flipping mechanism means that the filter box needs to be removed to empty the filter media for replacement. The process of sliding it out and repositioning it is relatively cumbersome and affects work efficiency. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a sulfide adsorption device for treating mine wastewater pollution. It solves the problem that while the device uses a filter box containing activated carbon to adsorb and purify sulfides, the filter box in the above-mentioned device is relatively fixed and lacks a flipping mechanism. The filter media needs to be replaced after a long period of use. The lack of a flipping mechanism means that the filter box needs to be removed to empty the filter media for replacement. The process of sliding it out and repositioning it is relatively cumbersome, which affects the work efficiency.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A sulfide adsorption device for treating mine wastewater pollution includes a purification box. A purification structure for adsorbing sulfides is rotatably connected inside the purification box. The purification structure includes a filter box rotatably connected inside the purification box. A pushing mechanism for flipping the purification structure is provided inside the purification box. The pushing mechanism includes a rectangular push rod and an eccentric connecting rod. The rectangular push rod is rotatably connected inside the purification box and rotatably connected to the outer surface of the filter box. The eccentric connecting rod is rotatably connected inside the purification box and rotatably connected to the outer surface of the rectangular push rod. An auxiliary mechanism for driving the flipping is provided on the outer surfaces of the filter box and the eccentric connecting rod. The auxiliary mechanism includes a handle block and a torsion spring. The handle block is fixedly connected to the outer surface of the eccentric connecting rod, and the torsion spring is sleeved on the outer surface of the filter box.

[0012] Preferably, a rotating shaft is fixedly connected to the outer surface of the filter box, and the rotating shaft is rotatably connected inside the purification chamber.

[0013] Preferably, a mesh baffle is slidably connected inside the filter box, and a T-shaped slider is fixedly connected to the outer surface of the mesh baffle.

[0014] Preferably, the filter box has a T-shaped groove inside, and the T-shaped slider is slidably connected inside the T-shaped groove.

[0015] Preferably, a discharge pipe is fixedly connected to the lower end of the purification box, and a set of backwash pipes is fixedly connected to the lower end of the purification box near the discharge pipe.

[0016] Preferably, all of the backwash pipes in a set are on the same vertical line as the filter box, and a water pump is fixedly connected to the side of the purification box away from the discharge pipe.

[0017] Preferably, the water pump has a water pipe inside, and a filter box is fitted onto the end of the water pipe away from the purification box.

[0018] Preferably, a feed pipe is fixedly connected to the upper end of the filter box.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The operator can hold the handle and rotate the eccentric connecting rod. The rotation of the eccentric connecting rod drives the rectangular push rod to move. The rectangular push rod pulls the filter box to rotate around the axis of rotation, causing it to flip. When the filter box rotates, it will compress the torsion spring. When the filter box loses its flipping force, the compressed torsion spring drives the axis of rotation to reset, returning the filter box to its initial position. When the filter material needs to be replaced, it can be flipped out without complicated disassembly and installation, saving time and labor costs. In the treatment of wastewater with relatively high sulfide content, the filter box can be flipped back and forth to allow the internal purification material to come into more full contact with the wastewater, improving the adsorption efficiency and purification effect of sulfides.

[0021] 2. After a period of purification, the backwashing pump can drive the backwashing pipe to inject cleaning fluid into the filter box for backwashing. During the backwashing process, the flip-up filter box, in conjunction with the cleaning fluid, allows the cleaning fluid to more comprehensively contact all parts inside the filter box, thereby improving the cleaning efficiency and effect.

[0028] This application provides a sulfide adsorption device for treating mine wastewater pollution. It effectively solves the problem of traditional devices that use activated carbon filter boxes to adsorb and purify sulfides. However, these devices often have fixed filter boxes lacking a flipping mechanism, requiring frequent replacement of the filter media. The lack of a flipping mechanism necessitates removing the filter box to empty the filter media, a cumbersome process that hinders efficiency. In this new device, the operator can grip the handle and rotate the eccentric connecting rod. This rotation drives a rectangular push rod, which in turn pulls the filter box around its axis, causing it to flip. The rotating filter box compresses a torsion spring. When the filter box loses its flipping force, the compressed torsion spring rotates the shaft back to its initial position. This allows the filter box to be flipped and emptied when needed, eliminating the need for complex disassembly and installation, saving time and labor costs. Furthermore, in treating wastewater with relatively high sulfide content, the filter box can be repeatedly flipped, allowing for more thorough contact between the internal purification material and the wastewater, thus improving adsorption efficiency and purification effect.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that the device adsorbs and purifies sulfides through a filter box containing activated carbon. However, the filter box in the above device is relatively fixed and lacks a flipping mechanism. The filter media needs to be replaced after long-term use. The lack of a flipping mechanism requires removing the filter box to empty the filter media for replacement. The process of sliding it out and repositioning it is relatively cumbersome, affecting work efficiency. The overall idea is as follows: A sulfide adsorption device for treating mine wastewater pollution includes a purification box 11. The purification box 11 has a purification structure for adsorbing sulfides rotatably connected inside. The purification structure includes a filter box 1. 2. Filter boxes 12 are rotatably connected inside the purification chamber 11. Filter boxes 12 contain purification material that adsorbs sulfide impurities. Adsorption and purification work is performed through filter boxes 12. The purification chamber 11 is equipped with a pushing mechanism for flipping the purification structure. The pushing mechanism includes a rectangular push rod 13 and an eccentric connecting rod 14. The rectangular push rod 13 is rotatably connected inside the purification chamber 11 and rotatably connected to the outer surface of the filter boxes 12. The eccentric connecting rod 14 is rotatably connected inside the purification chamber 11 and rotatably connected to the outer surface of the rectangular push rod 13. The rectangular push rod 13 is eccentrically connected inside the rectangular push rod 13. When the rectangular push rod 13 rotates, it pulls the two filter boxes 12 to generate… The filter box 12 and the eccentric connecting rod 14 are equipped with an auxiliary mechanism for driving the rotation. This mechanism includes a handle block 15 and a torsion spring 16. The handle block 15 is fixedly connected to the outer surface of the eccentric connecting rod 14, and the torsion spring 16 is sleeved on the outer surface of the filter box 12. Holding the handle block 15 allows the eccentric connecting rod 14 to be rotated. The eccentric connecting rod 14 provides a more suitable grip for the operator. A rotating shaft 17 is fixedly connected to the outer surface of the filter box 12 and is rotatably connected inside the purification chamber 11. The filter box 12 rotates within the purification chamber 11 around the rotating shaft 17. When the filter box 12 rotates, it compresses the torsion spring 16. When the filter box 12 loses its rotational force, the torsion spring 16... The rotating shaft 17 is rotated and reset. The operator can hold the handle block 15 and turn the eccentric connecting rod 14. The rotation of the eccentric connecting rod 14 drives the rectangular push rod 13 to move. The rectangular push rod 13 pulls the filter box 12 to rotate around the rotating shaft 17. When the filter box 12 rotates, it will compress the torsion spring 16. When the filter box 12 loses its rotation force, the compressed torsion spring 16 drives the rotating shaft 17 to rotate and reset, so that the filter box 12 returns to its initial position. The operator opens the baffle in the purification box 11 and puts the collection box and other components into the lower end of the filter box 12. The filter box 12 can be flipped out without additional removal and installation work. There is no need for complicated disassembly and installation process, saving time and labor costs.

[0031] A mesh baffle 18 is slidably connected inside the filter box 12. A T-shaped slider 19 is fixedly connected to the outer surface of the mesh baffle 18. A T-shaped groove 21 is opened inside the filter box 12, and the T-shaped slider 19 is slidably connected inside the T-shaped groove 21. The mesh baffle 18 slides inside the filter box 12 to block the purified material. The mesh baffle 18 slides in the filter box 12 via the T-shaped slider 19, which limits the vertical direction of the mesh baffle 18. The two ends of the purification box 11 away from the handle block 15 are screw-openable covers. The mesh baffle 18 can be pulled out by screwing open the covers. A discharge pipe 22 is fixedly connected to the lower end of the purification box 11. The purified material is discharged along the discharge pipe 22 for use. A set of backwash pipes 23 is fixedly connected to the lower end of the purification box 11 near the discharge pipe 22. The washing pipes 23 are all on the same vertical line as the filter box 12. After a long period of purification, the backwashing pump can drive the backwashing pipes 23 to inject cleaning fluid into the filter box 12 to achieve backwashing. During the backwashing process, the flip-over filter box 12 provides a cleaning effect. Inside the filter box 12, the grid baffle 18 slides in the T-shaped groove 21 through the T-shaped slider 19 to block the purified material and limit the vertical direction of the grid baffle 18. The screw-openable covers at both ends of the purification box 11 can be screwed open when needed to pull out the grid baffle 18. After a period of purification, the backwashing pump can drive the backwashing pipes 23 to inject cleaning fluid into the filter box 12 for backwashing. During the backwashing process, the flip-over filter box 12, together with the cleaning fluid, improves the cleaning effect.

[0032] A water pump 24 is fixedly connected to the side of the purification tank 11 away from the discharge pipe 22. A water pipe 25 is sleeved inside the water pump 24. A filter box 26 is sleeved at the end of the water pipe 25 away from the purification tank 11. Sulfides requiring adsorption and purification are first added to the filter box 26, which contains filter plates. The filter box 26 first filters and blocks the sulfides. The filtered wastewater is then pumped into the purification tank 11 along the water pipe 25 by starting the water pump 24. An inlet pipe 27 is fixedly connected to the upper end of the filter box 26. The wastewater flows along... The feed pipe 27 is inserted into the filter box 26 for feeding. First, the wastewater is fed into the filter box 26 along the feed pipe 27. The filter plate in the filter box 26 performs preliminary filtration and blocking of the wastewater, removing some larger impurities. The filtered wastewater is then pumped into the purification box 11 along the water pipe 25 by starting the water pump 24. After entering the purification box 11, the wastewater comes into contact with the purification material in the filter box 12 that is rotatably connected therein, and performs sulfide adsorption and purification. Finally, the purified material is discharged along the discharge pipe 22 for use.

[0033] To address the problems existing in the prior art, this utility model provides a sulfide adsorption device for treating mine wastewater pollution. Workers can hold the handle block 15 and rotate the eccentric connecting rod 14. The rotation of the eccentric connecting rod 14 drives the rectangular push rod 13 to move. The rectangular push rod 13 pulls the filter box 12 to rotate around the pivot 17. When the filter box 12 rotates, it compresses the torsion spring 16. When the filter box 12 loses its rotational force, the compressed torsion spring 16 drives the pivot 17 to rotate and reset, returning the filter box 12 to its initial position. When the filter material needs to be replaced, it can be flipped out, eliminating the need for complex disassembly and installation processes, saving time and labor costs. Furthermore, in the treatment of wastewater with relatively high sulfide content, the filter box 12 can be repeatedly flipped to ensure more thorough contact between the internal purification material and the wastewater, improving the adsorption efficiency and purification effect of sulfides.

[0035] Filter box 12: It contains purification material, which adsorbs sulfide impurities by contacting wastewater to achieve the purification function; its flip-top design makes it easy to replace the filter material and improve the purification effect.

[0036] Rectangular push rod 13: connects the eccentric connecting rod 14 and the filter box 12. When the eccentric connecting rod 14 rotates, it pulls the filter box 12 to flip.

[0037] Eccentric connecting rod 14: It drives the rectangular push rod 13 to move by rotating, thereby realizing the flipping operation of filter box 12;

[0038] Handle block 15: Fixed to the outer surface of the eccentric connecting rod 14, providing a gripping part for the operator to facilitate the rotation of the eccentric connecting rod 14;

[0039] Torsion spring 16: It is sleeved on the outer surface of filter box 12. It is compressed when filter box 12 is flipped. When it loses the flipping force, it drives filter box 12 to reset.

[0040] Rotating shaft 17: enables the filter box 12 to rotate inside the purification box 11 with it as the axis, thereby achieving a flipping action;

[0041] Mesh baffle 18: Slides within the filter box 12 to shield the purified material and prevent it from moving freely;

[0042] T-shaped slider 19: Fixed on the outer surface of the mesh baffle 18, it cooperates with the T-shaped groove 21 in the filter box 12 to limit the vertical direction of the mesh baffle 18;

[0043] T-shaped groove 21: It is formed inside the filter box 12 and cooperates with the T-shaped slider 19 to realize the sliding and limiting of the mesh baffle 18;

[0044] Discharge pipe 22: Used to discharge the purified material so that it can be collected and used;

[0045] Backwash tube 23: After a long period of purification, cleaning fluid is injected into the filter box 12 through a backwash pump, which, together with the flip-up filter box 12, improves the cleaning effect.

[0049] Feed pipe 27: Wastewater enters the filter box 26 through it, which is the inlet for wastewater to enter the entire treatment system.

[0050] Working principle:

[0051] First, the wastewater is fed into the filter box 26 through the feed pipe 27. The filter plates in the filter box 26 perform preliminary filtration and blockage of the wastewater, removing some larger impurities. The filtered wastewater is then pumped into the purification box 11 through the water pipe 25 by the pump 24. After entering the purification box 11, the wastewater comes into contact with the purification material in the filter box 12 that is rotatably connected therein, and the sulfide adsorption and purification work is carried out. Finally, the purified material is discharged through the discharge pipe 22 for use.

[0052] In the second step, the operator can hold the handle block 15 and rotate the eccentric connecting rod 14. The rotation of the eccentric connecting rod 14 drives the rectangular push rod 13 to move. The rectangular push rod 13 pulls the filter box 12 to rotate around the pivot 17. When the filter box 12 rotates, it will compress the torsion spring 16. When the filter box 12 loses its rotational force, the compressed torsion spring 16 drives the pivot 17 to rotate and reset, so that the filter box 12 returns to its initial position. The operator can then open the baffle inside the purification box 11 and place the collection box and other components into the lower part of the filter box 12. The filter box 12 can be flipped out without additional removal and installation work, eliminating the need for complicated procedures. The disassembly and installation process saves time and labor costs. Inside the filter box 12, the mesh baffle 18 slides in the T-shaped groove 21 via the T-shaped slider 19 to block the purified material and limit the vertical direction of the mesh baffle 18. The screw-on covers at both ends of the purification box 11 can be screwed open when needed to pull out the mesh baffle 18. After a period of purification treatment, the backwashing pump can drive the backwash pipe 23 to inject cleaning liquid into the filter box 12 for backwashing. During the backwashing process, the flip-up filter box 12 works in conjunction with the cleaning liquid to improve the cleaning effect.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
