Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of deep-cone thickeners, and particularly relates to a pulp feeding assembly of a deep-cone thickener. BACKGROUND

[0002] Thickeners are widely used in the field of mineral processing, for example, thickeners can be used to thicken tailings slurry in a concentrator. The diameter of a conventional thickener is generally greater than its height, for example, the diameter can reach 100 meters, and the diameter is 10 meters, so the cone angle is large. The diameter of a deep-cone thickener is generally less than its height, for example, the diameter is 11 meters and the height is 20 meters, so the cone angle is small and the cone is deep.

[0003] For example, patent number CN200710304087.1 discloses a deep-cone thickener, which comprises a main body, a stirring device, a driving device, and a circulation system. The main body comprises an upper cylindrical portion, a conical portion below the upper cylindrical portion, and a lower cylindrical portion below the conical portion. The stirring device is arranged in the main body. The driving device drives the stirring device to rotate to stir the slurry in the main body. The circulation system is arranged outside the main body and connects the lower part of the lower cylindrical portion with the upper part of the lower cylindrical portion and the upper cylindrical portion, respectively, to transport the slurry from the lower part of the lower cylindrical portion to the upper part of the lower cylindrical portion and / or the upper cylindrical portion. In other words, the deep-cone thickener has two circulation systems, i.e., an upper circulation system and a lower circulation system. The upper circulation system is used to transport the underflow slurry from the lower part of the lower cylindrical portion to the position between the top end of the conical portion and the top end of the upper cylindrical portion. The lower circulation system is used to transport the underflow slurry from the lower part of the lower cylindrical portion to the lower part of the lower cylindrical portion.

[0004] Therefore, in order to solve the problem that the deep-cone thickener needs to be fed into the interior through a pulp feeding assembly during use to stir the slurry and prevent the slurry from sticking to the inner wall for subsequent cleaning, and the stirring mechanism can be easily disassembled to improve the subsequent use efficiency, a pulp feeding assembly is designed to stir the slurry and prevent the slurry from sticking to the inner wall for subsequent cleaning. SUMMARY

[0005] In order to solve the problem that the deep-cone thickener needs to be fed into the interior through a pulp feeding assembly during use to stir the slurry and prevent the slurry from sticking to the inner wall for subsequent cleaning, and the stirring mechanism can be easily disassembled to improve the subsequent use efficiency.

[0008] Preferably, the inside of movable plate is provided with through hole, and the insertion rod is connected with the movable plate through the through hole.

[0009] Preferably, the lower portion of stirring rod is provided with connecting sleeve ring, and the outside of connecting sleeve ring is provided with four-jaw stirring blade, so as to improve the stirring efficiency of slurry.

[0010] Preferably, the outside of deep cone thickener is sleeved with reinforcing plate, and the lower portion of reinforcing plate is provided with a plurality of support frames arranged uniformly in diameter, so as to support and stabilize.

[0011] Preferably, the upper portion of deep cone thickener is provided with pulp feeding groove, and the support frames are fixedly provided with reinforcing rods, so as to strengthen the stability between the support frames.

[0012] Preferably, the upper end surface of anti-blocking mechanism is fixedly provided with pulp feeding hopper, and the pulp feeding hopper and the anti-blocking mechanism are integrally formed by welding, so as to be more firm and convenient for slurry to enter.

[0013] Preferably, the limiting plate is arranged between the plug and the spring, and the surface of movable plate is provided with anti-skid pad, so as to prevent slipping when disassembling.

[0014] The utility model has the advantages of:

[0015] 1. When the spiral rod rotates, the worm in the middle also starts to rotate. The rotation of the worm drives the worm wheel that meshes with it at its front end to rotate. The rotation of the worm wheel causes the connecting shaft in the middle of the worm wheel to rotate, and the stirring blades at its upper and lower ends also start to rotate. This makes the slurry entering the interior agitated to prevent clogging. At the same time, the stirring rod and stirring blades inside the deep cone thickener also move together to agitate the material inside, preventing internal sticking and affecting subsequent cleaning.

[0016] 2. When disassembling the stirring rod, firstly, the movable plate at one end is flipped by the drive of the movable shaft. At the same time, the insert rod connected to it through the through hole is also released from the fixation of the movable plate. Then, pull the stirring rod out to one end, and under the action of tension, the insert block inserted into the slot will slowly disengage from the slot. Finally, the locking block will also disengage from the slot to complete the disassembly. When installing, the locking block at one end of the stirring rod is inserted into the slot inside the installation coupling for fixation. At the same time, the insert block on one side of the slot is pressed to one side. After the locking block is inserted into the slot, the spring is released, causing the insert block to pop out and insert into the slot for fixation. Finally, the movable plate at one end is folded over by the movable shaft, so that the insert rod is connected to the movable plate through the through hole to complete the fixation. This disassembly and assembly method is relatively simple, thereby improving subsequent work efficiency. Attached Figure Description
