Description

Technical Field

[0001] The utility model relates to a medium-consistency sand removal device, in particular to a medium-consistency sand removal device, and belongs to the technical field of medium-consistency sand removal. Background Art

[0002] Medium-consistency desander refers to the process of using specific equipment (such as a medium-consistency desander or medium-consistency deslagging device) to separate sand, gravel, slag and impurities from the slurry or liquid when the concentration is medium through centrifugal force or other physical principles. It can effectively separate these impurities and slag from the pulp, improve the quality and usability of the pulp, and ensure the quality of the final product.

[0003] The existing medium-consistency sand removal device has a simple structure and can only remove sand and gravel in the slurry, but cannot filter other impurities in the slurry. After the slurry is poured into the sand removal device, the impurities inside it may cause blockage of the device, and the slurry cannot be stirred, which may cause the slurry to clump and be unable to be discharged, thereby affecting the subsequent use of the device.

[0004] Therefore, there is an urgent need to improve a medium-consistency sand removal device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a medium-consistency sand removal device, which can not only remove sand and gravel in the slurry but also filter other impurities through the setting of the filtering and stirring structure, so as to avoid the impurities from clogging inside the sand removal device body after the slurry is poured into the sand removal device body. Before the slurry is poured into the conical tube, the multiple first filter holes on the filter frame will filter the impurities in the slurry, and then flow into the sand removal device body through the discharge port below the conical tube, and the starting motor drives the first gear to rotate. While the first gear rotates, the second gear also drives the stirring rod to start rotating to stir the slurry in the sand removal device body. Finally, the slurry after desanding will be discharged for use through the slurry outlet below the sand removal device body. Since the slurry outlet is provided with a screen for isolating sand and gravel, the sand and gravel can be concentrated in the sand removal device body for unified treatment, and the slurry after sand discharge is discharged for use, thus avoiding the situation where the slurry cannot be discharged due to agglomeration, and will not affect subsequent use.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:

[0007] A medium-consistency sand removal device comprises a support platform and a sand removal device body, a conical tube is arranged above the sand removal device body, the sand removal device body and the conical tube are connected by a plurality of support rods, a filtering and stirring structure is provided on the sand removal device body, the filtering and stirring structure comprises a filter frame installed above the conical tube, a plurality of first filter holes are opened at the bottom of the filter frame, a motor is fixedly installed on the top of the support platform, a first gear is fixedly installed on the output end of the motor, a stirring rod is movably installed inside the sand removal device body, a second gear meshing with the first gear is fixedly installed on one end of the stirring rod, and a slurry outlet is provided below the sand removal device body.

[0008] Preferably, a plurality of protrusions are fixedly mounted on the inner wall of the conical tube, a filter screen is placed above the protrusions, a plurality of second filter holes are opened on the filter screen, and a handle is fixedly mounted on the top of the protrusion.

[0012] Preferably, threaded holes are provided on the support rod and the filter frame, and bolts connected to the support rod are movably mounted on the filter frame.

[0013] Preferably, a plurality of insert rods are fixedly mounted on one end of the bolt.

[0014] The utility model has at least the following beneficial effects:

[0015] By setting up the filtering and stirring structure, not only the sand and gravel in the slurry can be removed, but also other impurities can be filtered to avoid clogging caused by impurities inside the sand removal device body after the slurry is poured into the sand removal device body. Before the slurry is poured into the conical tube, the multiple first filter holes on the filter frame will filter the impurities in the slurry, and then it will flow into the sand removal device body through the discharge port below the conical tube.

[0026] A medium-consistency sand removal device comprises a support platform 1 and a sand removal device body 2, a conical tube 3 is arranged above the sand removal device body 2, the sand removal device body 2 and the conical tube 3 are connected by a plurality of support rods 4, a filtering and stirring structure 5 is provided on the sand removal device body 2, the filtering and stirring structure 5 comprises a filter frame 6 installed above the conical tube 3, a plurality of first filtering holes 7 are provided at the bottom of the filter frame 6, a motor 8 is fixedly installed on the top of the support platform 1, a first gear 9 is fixedly installed on the output end of the motor 8, a stirring rod 10 is movably installed inside the sand removal device body 2, and a second gear 11 meshing with the first gear 9 is fixedly installed on one end of the stirring rod 10, and a slurry outlet is provided below the sand removal device body 2. By setting the filtering and stirring structure 5, not only the sand and gravel in the slurry can be removed, but also the Other impurities are filtered to prevent impurities from clogging the inside of the sand removal device body 2 after the slurry is poured into the sand removal device body 2. Before the slurry is poured into the conical tube 3, the multiple first filter holes 7 on the filter frame 6 will filter the impurities in the slurry. Then, the slurry flows into the sand removal device body 2 through the discharge port below the conical tube 3. The motor 8 is started to drive the first gear 9 to rotate. While the first gear 9 rotates, the second gear 11 also drives the stirring rod 10 to start rotating to stir the slurry in the sand removal device body 2. Finally, the slurry after desanding will be discharged through the slurry outlet below the sand removal device body 2 for use. Since a screen for isolating sand and gravel is provided at the slurry outlet, the sand and gravel can be concentrated in the sand removal device body 2 for unified treatment. The slurry after sand discharge is discharged for use, avoiding the situation where the slurry cannot be discharged due to agglomeration, and will not affect subsequent use.

[0027] like Figure 4As shown, a plurality of protrusions 12 are fixedly mounted on the inner wall of the conical tube 3, a filter screen 13 is placed above the protrusions 12, a plurality of second filter holes 14 are opened on the filter screen 13, and a handle 15 is fixedly mounted on the top of the protrusion 12. Through the arrangement of the protrusions 12, the filter screen 13, the second filter holes 14 and the handle 15, the fine impurities in the slurry can be further filtered. The plurality of protrusions 12 can support the filter screen 13, thereby preventing the filter screen 13 from being impacted by a large amount of slurry and being stuck in the interior of the conical tube 3. The filter screen 13 can be conveniently removed and cleaned through the handle 15.

[0028] like Figure 3 As shown, a protective cover 16 is fixedly installed on one side of the sand removal device body 2, and a plurality of heat dissipation holes 17 are opened on the protective cover 16. Through the setting of the protective cover 16 and the heat dissipation holes 17, the motor 8 can be protected and the user's hands can be prevented from accidentally touching the first gear 9 and the second gear 11 and causing injury. The heat dissipation holes 17 can dissipate the heat inside the protective cover 16 to avoid damage to the motor 8.

[0029] like Figure 3 As shown, a cover plate 18 is movably mounted on one side of the protective cover 16, a first magnetic ring 19 is fixedly mounted on the protective cover 16, and a second magnetic ring 20 magnetically connected to the first magnetic ring 19 is fixedly mounted on one end of the cover plate 18. By arranging the cover plate 18, the first magnetic ring 19 and the second magnetic ring 20, the first magnetic ring 19 and the first gear 9 are attracted to each other, so that the cover plate 18 can be fixed on the protective cover 16 to achieve a sealing effect. Due to the characteristics of the first magnetic ring 19 and the second magnetic ring 20, the cover plate 18 can be removed by directly pulling it, thereby facilitating the maintenance of the motor 8.

[0030] like Figure 5 As shown, a plurality of electric telescopic rods 21 are fixedly installed below the support platform 1, and a block 22 is fixedly installed at the output end of the electric telescopic rod 21, which is in contact with the slurry outlet below the sand removal device body 2. By setting the electric telescopic rod 21 and the block 22, the plurality of electric telescopic rods 21 are started at the same time to drive the block 22 to move away from each other or move away from each other, so that the slurry outlet can be opened or closed, which is convenient for the discharge of the slurry.

[0031] like Figure 6 As shown, threaded holes 23 are provided on the support rod 4 and the filter frame 6, and bolts 24 connected to the support rod 4 are movably installed on the filter frame 6. Through the arrangement of the threaded holes 23 and the bolts 24, multiple bolts 24 are screwed into the threaded holes 23 to connect the filter frame 6 to the support rod 4, so as to fix the bolts 24 to prevent the filter frame 6 from shaking and falling due to the impact of the slurry. By loosening the bolts 24, the filter frame 6 can be disassembled to clean the impurities filtered inside it.

[0032] like Figure 6As shown, a plurality of insert rods 25 are fixedly installed at one end of the bolt 24. By setting the insert rods 25, the force-bearing area of ​​one end of the bolt 24 can be increased, making it easier for the staff to tighten the bolt 24.

[0033] In this embodiment, if Figures 1-6 As shown, the working process of a medium-consistency sand removal device provided in this embodiment is as follows:

[0034] Before the slurry is poured into the conical tube 3, the multiple first filter holes 7 on the filter frame 6 will filter the impurities in the slurry, and then it will flow into the desanding device body 2 through the discharge port below the conical tube 3. The starting motor 8 drives the first gear 9 to rotate. While the first gear 9 rotates, the second gear 11 also drives the stirring rod 10 to start rotating to stir the slurry in the desanding device body 2. Finally, the desanded slurry will be discharged for use through the slurry outlet below the desanding device body 2. Since the slurry outlet is provided with a screen to isolate sand and gravel, the sand and gravel can be concentrated in the desanding device body 2 for unified treatment, and the slurry after sand discharge is discharged for use, avoiding the situation where the slurry cannot be discharged due to caking, and will not affect subsequent use.

[0035] In summary, in this embodiment, according to a medium-consistency sand removal device of this embodiment, the fine impurities in the slurry can be further filtered through the arrangement of the protrusions 12, the filter screen 13, the second filter hole 14 and the handle 15.

The handle 15 can facilitate the removal and cleaning of the filter screen 13. The arrangement of the protective cover 16 and the heat dissipation holes 17 can protect the motor 8 and prevent the user's hands from accidentally touching the first gear 9 and the second gear 11 and causing injury. The heat dissipation holes 17 can dissipate the heat inside the protective cover 16 to avoid damage to the motor 8. Through the arrangement of the cover plate 18, the first magnetic ring 19 and the second magnetic ring 20, the first magnetic ring 19 and the first gear 9 are attracted to each other, so that the cover plate 18 can be fixed in the protective cover. The shield 16 has a sealing effect. Due to the characteristics of the first magnetic ring 19 and the second magnetic ring 20, the cover 18 can be removed by directly pulling it, which facilitates the maintenance of the motor 8. By setting the electric telescopic rod 21 and the block 22, multiple electric telescopic rods 21 are started at the same time to drive the blocks 22 to move away from each other or move away from each other, so that the slurry outlet can be opened or closed, which is convenient for the discharge of slurry. By setting the threaded holes 23 and the bolts 24, multiple bolts 24 are screwed into the threaded holes 23 to connect the filter frame 6 to the support rod 4, and the bolts 24 can be fixed to prevent the filter frame 6 from shaking and falling due to the impact of the slurry. By loosening the bolts 24, the filter frame 6 can be disassembled to clean the impurities filtered inside it. By setting the insertion rod 25, the force area at one end of the bolt 24 can be increased, which makes it easier for the staff to tighten the bolt 24.
