Description

Technical Field

[0001] This utility model relates to the field of sludge removal technology, specifically a sludge removal device for mine water treatment to prevent clogging. Background Technology

[0002] When treating mine water, the silt in the mine is also treated. The silt is usually cleaned up by using a silt pump, also known as a centrifugal pump, to suck up and remove it.

[0003] The prior art (Chinese patent application number CN201920458145.4, published on January 7, 2020) describes a silt removal device for water conservancy projects that prevents clogging. The device includes a mounting base and an anti-clogging device connected below the silt extraction pipe. The anti-clogging device includes a housing with a cavity inside. A second motor is installed within the cavity. When the first silt extraction pump extracts silt, the second motor is activated, causing all the silt entering the cavity to be broken up by the crushing blades on the drive shaft, preventing clogging of the silt extraction pipe. Three bearings are installed on the horizontal plate. When discharging silt from the storage tank, the first motor can be activated first, driving the horizontal plate to rotate via the shaft. This causes the first, second, and third rotating rods to rotate due to the resistance of the silt, breaking up the silt and facilitating discharge without clogging. The advantages are: the device has a simple structure, is easy to use, and can prevent machine clogging during silt removal, thus avoiding disruption to the project's progress and efficiency.

[0004] Current sludge cleaning devices, when directly pumping sludge, are prone to clogging the pump body due to large solid impurities contained in the sludge, which can even damage the pump body in severe cases. When cleaning sludge by crushing it, stones and other debris contained in the sludge are difficult to crush, which can easily damage the blades and cause damage to the pump body due to the inhalation of particles, thus reducing the sludge cleaning efficiency and the service life of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a sludge cleaning device for mine water treatment that prevents clogging, in order to solve the problems mentioned in the background art. When the current sludge cleaning device directly extracts sludge, large solid impurities contained in the sludge can easily cause clogging of the pump body, and in severe cases, damage to the pump body. When cleaning by crushing the sludge, stones and other objects contained in the sludge are difficult to crush, which can easily damage the blades and cause damage to the pump body due to the inhalation of particles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sludge cleaning device for mine water treatment to prevent clogging, comprising a base and a sludge pump for extracting sludge. The sludge pump is installed above the base, and a treatment tank is provided above the base. A connecting pipe is provided at the bottom of the treatment tank, and the connecting pipe is connected to the sludge pump. A suction pipe is connected above the treatment tank, through which mine sludge is extracted into the treatment tank. A cover is provided above the treatment tank, and the cover is connected to the suction pipe. The cover and the treatment tank are detachably connected. A connecting port is provided in the middle of the cover, and the connecting port is interconnected with the suction pipe. A filtration mechanism is provided inside the treatment tank to filter and intercept the sludge entering the connecting pipe, so that it remains inside the treatment tank.

[0007] To further optimize this technical solution, a threaded connection is formed between the cover and the treatment tank, and an annular sealing ring is fixed below the cover. The outer side of the sealing ring is designed with an inclined structure to seal the connection between the cover and the treatment tank.

[0008] To further optimize this technical solution, the filtration mechanism includes a filter cylinder and a positioning ring;

[0009] The filter cartridge is installed inside the treatment tank and is located below the connecting port;

[0010] The positioning ring is fixed to the bottom of the cover and nested inside the top of the filter cylinder.

[0011] To further optimize this technical solution, a rotating support mechanism is provided on the outer side of the filter cartridge, and a rotating drive mechanism is provided on the top of the filter cartridge to provide rotational power for the filter cartridge.

[0012] To further optimize this technical solution, the rotating support mechanism includes a support shaft, a docking block, and a docking groove;

[0013] The support shaft is rotatably mounted at the bottom of the processing tank;

[0014] The docking block is fixed above the support shaft;

[0015] The mating groove is formed on the lower surface of the filter cartridge, and the mating groove and the mating block form a concave-convex fit structure.

[0016] To further optimize this technical solution, the positioning ring is equipped with ball bearings inside, which contact the upper surface of the filter cylinder to assist the rotation of the filter cylinder.

[0017] To further optimize this technical solution, the rotary drive mechanism includes a fixed ring, a first magnet, a second magnet, a drive ring, a transmission gear, and a motor;

[0018] A retaining ring is used to fix the filter cartridge to the outside.

[0022] The transmission gear is positioned on the outside of the drive ring and forms a meshing connection with the drive ring;

[0023] The motor is connected to the transmission gear to control the rotation of the transmission gear.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] (1) By setting up the treatment tank and cooperating with the filtration mechanism, the impurities in the sludge are intercepted inside the treatment tank, so that the sludge can be cleaned and discharged smoothly through the sludge pump. This can protect the sludge pump, avoid blockage during the sludge discharge process, and improve its sludge treatment efficiency.

[0026] (2) The connection between the cover and the treatment tank creates a closed space inside the treatment tank. The treatment tank uses internal negative pressure to create an adsorption effect on the suction pipe, and the sludge sucked into the treatment tank is temporarily stored. The sludge filtered inside the treatment tank is discharged through the connecting pipe into the sludge pump.

[0027] (3) The filter cartridge is rotatably installed inside the treatment tank. The subsequent drive of the filter cartridge adopts non-contact drive, which keeps the treatment tank well sealed, so that the suction pipe can maintain a stable adsorption force. When the filter cartridge rotates, the sludge can pass through better, avoiding filter cartridge blockage.

[0028] (4) The filter cartridge and the treatment tank are detachable. After the cover is opened, the filter cartridge can be directly removed from the treatment tank, which makes it convenient to clean the impurities filtered out of the filter cartridge. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-6 Example 1: This utility model provides the following technical solution: a sludge cleaning device for mine water treatment to prevent clogging, including a base 1 and a sludge pump 2 for pumping sludge. The sludge pump 2 is installed above the base 1. A treatment tank 4 is set above the base 1, and a connecting pipe 3 is set at the bottom of the treatment tank 4. The connecting pipe 3 is connected to the sludge pump 2. A suction pipe 5 is connected above the treatment tank 4. The mine sludge is pumped into the treatment tank 4 through the suction pipe 5. A cover 6 is set above the treatment tank 4. The cover 6 is connected to the suction pipe 5, and the cover 6 and the treatment tank 4 are detachably connected. A connecting port 7 is opened in the middle of the cover 6. The connecting port 7 is connected to the suction pipe 5. A filter mechanism is set inside the treatment tank 4 to filter and intercept the sludge entering the connecting pipe 3 of the treatment tank 4, so that it stays inside the treatment tank 4.

[0038] During use, the sludge pump 2, in conjunction with the connecting pipe 3, can be used to draw air into the treatment tank 4, creating a negative pressure inside the treatment tank 4. This negative pressure draws air into the suction pipe 5, generating suction force. The sludge is then cleaned through the suction pipe 5. The sludge enters the interior of the treatment tank 4 through the suction pipe 5 and the connecting port 7, is filtered by the filtration mechanism, and then sucked into the connecting pipe 3. Finally, it is discharged outward through the sludge pump 2, thus achieving the cleaning of the sludge.

[0039] Example 2: Based on Example 1, a threaded connection is made between the cover 6 and the treatment tank 4, and an annular sealing ring 8 is fixed below the cover 6. The outer side of the sealing ring 8 is designed with an inclined structure to seal the connection between the cover 6 and the treatment tank 4. The filtration mechanism includes a filter cylinder 9 and a positioning ring 13. The filter cylinder 9 is disposed inside the treatment tank 4 and is located below the connecting port 7. The positioning ring 13 is fixed below the cover 6 and is nested above the filter cylinder 9. A rotating support mechanism is provided on the outer side of the filter cylinder 9, and a rotating drive mechanism is provided on the upper side of the filter cylinder 9 to provide rotational power for the filter cylinder 9.

[0040] After the cover 6 is connected to the treatment tank 4, the inside of the treatment tank 4 is sealed. Subsequently, the sludge enters the filter cylinder 9. After the sludge is filtered out through the filter cylinder 9, it enters the connecting pipe 3. Impurities will be intercepted inside the filter cylinder 9, thereby protecting the sludge pump 2 and preventing it from getting blocked. The positioning ring 13 provides positioning support for the filter cylinder 9, keeping it stable inside the treatment tank 4.

[0041] Example 3: Based on Example 2, a rotating support mechanism is disclosed, including a support shaft 10, a docking block 11, and a docking groove 12. The support shaft 10 is rotatably mounted on the bottom of the processing tank 4. The docking block 11 is fixed above the support shaft 10. The docking groove 12 is formed on the lower surface of the filter cylinder 9. The docking groove 12 and the docking block 11 form a concave-convex fit structure. The positioning ring 13 has balls inside, which contact the upper surface of the filter cylinder 9 to assist the rotation of the filter cylinder 9. The rotating drive mechanism includes a fixed ring 14, a first magnet 15, a second magnet 16, a drive ring 17, and a transmission ring. The drive gear 18 and motor 19, the fixed ring 14, are fixed on the outside of the filter cylinder 9. The first magnet 15 is fixed above the fixed ring 14. The second magnet 16 is set above the cover 6. The second magnet 16 and the first magnet 15 attract each other. The drive ring 17 is fixed above the second magnet 16 and forms a rotatable connection with the cover 6. The outer surface of the drive ring 17 has a toothed block structure. The transmission gear 18 is set on the outside of the drive ring 17 and forms a meshing connection with the drive ring 17. The motor 19 is connected to the transmission gear 18 to control the rotation of the transmission gear 18.

[0042] When it is necessary to drive the filter cylinder 9 to rotate, the motor 19 can be started to drive the transmission gear 18 to rotate. The transmission gear 18 drives the drive ring 17 to rotate through meshing with the drive ring 17, causing the drive ring 17 to drive the second magnet 16 to move. The second magnet 16 drives the first magnet 15 and the fixed ring 14 to move through mutual attraction with the first magnet 15, causing the filter cylinder 9 to rotate. When it is necessary to process the impurities in the filter cylinder 9, the cover 6 can be opened to expose the filter cylinder 9. Then the filter cylinder 9 can be pulled out from the processing tank 4, and the connection between the docking groove 12 and the docking block 11 can be released to clean the impurities in the filter cylinder 9.
