Description

Technical Field

[0001] The utility model relates to the technical field of mineral desludging, in particular to a rapid desludging classifier. Background Art

[0002] In the current mineral processing technology, when the feed slurry has a high mud content and is mixed with coarse and fine particle materials, it will be unfavorable to the subsequent process and affect the mineral processing indicators. Therefore, at this time, it is usually necessary to pre-de-sludge the slurry or classify the coarse and fine particles before further processing.

[0003] The patent document with the prior art publication number CN214160483U provides an efficient mud separation equipment for mineral processing. This solution can not only dry the mud through the cooperation of a stirring motor, a motor shaft, a stirring shaft, a fan, a heating tube and a heating wire, but also improve the drying effect through the stirring shaft, making the drying more uniform, and can play a role in the initial separation of mud and ore. Then, by opening the sealing plate, the mud and ore that have been initially separated fall down on the screening net. At this time, the screening net sieves the dried mud down by shaking up and down, and the ore rolls to the right along the screening net, solving the problem that the efficient mud separation equipment for mineral processing is difficult to dry when desludging, and the desludging effect is poor because some mud is relatively wet. However, in the existing CN214160483U patent, the ore mud mixture is dried and crushed, and a large amount of tiny dust is generated after the mud is crushed. The dust flies in the air and is easily absorbed by the staff, which seriously endangers the health of the body in the long run. Therefore, a fast desludging classifier is proposed.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] See also Figure 1-4 A rapid desludging classifier comprises an outer barrel 1 and a discharging mechanism 9. An inner filter barrel 2 is arranged inside the outer barrel 1, and a top cover 3 is installed on the top of the inner filter barrel 2. Two feeding pipes 4 are arranged on the upper surface of the top cover 3. A main rod 5 runs through the inner filter barrel 2, and a first stirring rod 6 is welded on the outer surface of the main rod 5. A motor 7 is connected to the top end of the first stirring rod 6. A second stirring rod 8 is welded to the inner wall of the inner filter barrel 2. The top end of the main rod 5 passes through the top cover 3 through a bearing and is connected to the output end of the motor 7, and a plurality of first stirring rods 6 are symmetrical about the central axis of the main rod 5. , and the first stirring rod 6 and the second stirring rod 8 are staggered, the two feeding pipes 4 are respectively used to inject the mud-ore mixture and the clean water into the inner filter barrel 2, and the motor 7 is started. The motor 7 drives the main rod 5 and the first stirring rod 6 to rotate, and the mud-ore mixture and the clean water are stirred, so that the mud in the mud-ore mixture is quickly dissolved in the water, and the mud and the ore are separated. The setting of the second stirring rod 8 can prevent the mud-ore mixture from always rotating in the same direction, and accelerate the separation of the mud and the ore. Two pull rings 15 are welded on the upper surface of the top cover 3, and the left and right ends of the top cover 3 are rotatably connected with lock buckles 16.

[0024] The discharge mechanism 9 is arranged at the middle of the lower surface of the inner filter barrel 2. The discharge mechanism 9 includes a discharge pipe 901, a longitudinal rod 902 and a spiral blade 903. The discharge pipe 901 is provided with a longitudinal rod 902 inside, and the spiral blade 903 is welded on the outer surface of the longitudinal rod 902, and the longitudinal rod 902 is welded to the lower end of the main rod 5. When the mud is completely dissolved in the water, the sewage is discharged, and only minerals are left in the inner filter barrel 2. Then, the valve on the discharge pipe 901 is opened, and the longitudinal rod 902 rotates with the main rod 5. The spiral blade 903 rotates to push the minerals downward, which is conducive to pushing the minerals out of the discharge pipe 901. This setting can reduce the risk of the discharge pipe 901 being blocked. The outer barrel 1 is connected to the sewage pipe 10, and the bottom of the outer barrel 1 is welded with a bottom bracket 17. The lower surface edge of the inner filter barrel 2 is provided with a sealing mechanism 11, which includes an outer ring frame 1101, a rubber pad 1102 and an inner ring frame 1103. The inner surface of the lower surface of the outer ring frame 1101 is The outer ring frame 1101 is concave inward, and the concave surface of the outer ring frame 1101 is fitted with a rubber pad 1102, and the inner side of the rubber pad 1102 is clamped with an inner ring frame 1103. The sealing mechanism 11 is set to enhance the sealing of the bottom when the outer barrel 1 and the inner filter barrel 2 are spliced. The discharge mechanism 9 passes through the middle of the inner ring frame 1103, and the bottom of the inner ring frame 1103 is welded to the outer barrel 1. This setting prevents the discharge mechanism 9 from being fixed to the outer barrel 1. When the staff holds the pull ring 15 and lifts it, the inner filter barrel can be 2 is pulled out from the outer barrel 1, so that the inner filter barrel 2 and the outer barrel 1 can be disassembled and cleaned conveniently. A connecting rod 12 is fixedly installed on the outer wall of the inner filter barrel 2, and a limiting strip 13 is fixed on one end of the connecting rod 12 away from the inner filter barrel 2. A limiting groove 14 matching with the limiting strip 13 is opened on the inner wall of the outer barrel 1. By aligning the limiting strip 13 with the limiting groove 14 and inserting it, it is convenient to accurately cover the outer circular ring frame 1101 on the outer side of the inner circular ring frame 1103, thereby reducing the difficulty of assembling the inner filter barrel 2 and the outer barrel 1.

[0025] Working principle: When in use, first inject the mud-ore mixture and clean water into the inner filter barrel 2 through the two feeding pipes 4, start the motor 7, and the motor 7 drives the main rod 5 and the first stirring rod 6 to rotate to stir the mud-ore mixture and the clean water. During the stirring process, the mud attached to the minerals is removed, so that the mud in the mud-ore mixture is quickly dissolved in the water to form muddy water. The setting of the second stirring rod 8 can prevent the mud-ore mixture from always rotating in the same direction, accelerate the separation of mud and ore, and after the separation is completed, open the valve on the sewage pipe 10 to allow the muddy water to flow out of the sewage pipe 10. The pipe 10 is discharged, and only minerals are left in the inner filter barrel 2. Then the valve on the discharge pipe 901 is opened, and the longitudinal rod 902 rotates with the main rod 5, so the spiral blade 903 rotates to push the minerals downward, which is beneficial to push the minerals out of the discharge pipe 901, thus realizing the separation of mud and ore. After the device is used, the lock 16 is opened, the pull ring 15 is held and lifted, and the limit bar 13 moves up vertically along the limit groove 14 until the inner filter barrel 2 is pulled out of the outer barrel 1, so as to facilitate the disassembly and cleaning of the inner filter barrel 2 and the outer barrel 1.
