[0002] The combined buffer bin for pulp transportation that is convenient for maintenance is a device used in a pulp transportation system, aiming to provide the functions of buffering and storing pulp, and being convenient for maintenance and repair at the same time. This kind of bin usually adopts a combined design and can be assembled and disassembled according to actual needs, so as to facilitate internal inspection, cleaning or replacement of worn parts without shutting down the machine. Specifically, during the transportation of pulp, impacts and fluctuations may occur due to unstable flow rate, pipeline pressure changes, etc. The buffer bin can absorb these impacts, stabilize the flow of pulp, and prevent damage to subsequent equipment.

[0003] Chinese Patent with Publication No. CN208943605U discloses a new type of gold ore pulp buffer bin, which includes a buffer bin. A number of inclined buffer plates are cross - misaligned and hinged on the inner side walls of both sides of the buffer bin. A buffer mechanism is arranged at the lower part of the buffer plate. By setting a telescopic buffer mechanism under the buffer plate, the impact force brought by the pulp on the buffer plate can be removed, changing the rigid impact of the buffer plate under the impact of pulp to a flexible impact, so that the root of the buffer bin will not crack and fall off from the buffer bin, and the service life is relatively long.

[0004] During the use of the pulp buffer bin of the above - mentioned patent, the discharge pipe will continuously contact the flowing and transporting pulp, and the discharge pipe will be damaged due to continuous friction. When replacing the discharge pipe, it is necessary to carry out high - altitude operation with the upper and lower platforms crossing each other, which is not conducive to safe maintenance and is prone to safety accidents, reducing the production efficiency of the concentrator.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] In order to solve the problem that in the process of using the existing pulp buffer tank, the discharge pipe will continuously contact the flowing and transporting pulp, and the continuous friction of the discharge pipe will cause damage due to friction. When replacing the discharge pipe, it is necessary to carry out cross-altitude operation on the upper and lower platforms, which is not conducive to safe maintenance and prone to safety accidents, reducing the production efficiency of the concentrator. The following technical solutions are provided in this embodiment:

[0021] A combined buffer bin for pulp transportation that is convenient for maintenance, including a feed bin 1. A through installation cavity 12 is provided at the lower end inside the feed bin 1. A sealing pressure plate 6 is provided at the lower end inside the feed bin 1. As Figure 2 、 Figure 3 and Figure 4 shown, a detachable discharge pipe 3 is provided on the side of the sealing pressure plate 6 facing the installation cavity 12. After the sealing pressure plate 6 fits against the inner wall of the lower end of the feed bin 1, the discharge pipe 3 can be suspended and fixed.

[0022] In this embodiment, a sealing sleeve 2 is circumferentially arranged outside the discharge pipe 3, and the sealing sleeve 2 is fixedly welded to the feed bin 1. As Figure 1 shown, the installed discharge pipe 3 can be fixed inside the sealing sleeve 2. A discharge port 15 is provided through the inside of the discharge pipe 3, and the discharge port 15 penetrates and extends to the upper and lower ends of the discharge pipe 3.

[0023] In this embodiment, as Figure 2 and Figure 3 shown, lifting lugs 7 for grasping are provided on both sides of the upper end of the sealing pressure plate 6, and the lifting lugs 7 and the sealing pressure plate 6 are fixedly connected by bolts 8. The lifting lugs 7 connected by bolts 8 can lift the sealing pressure plate 6, and lifting the sealing pressure plate 6 is convenient for taking out the lower discharge pipe 3 and facilitating the replacement and maintenance of the discharge pipe 3.

[0024] In this embodiment, an internal threaded wall 11 is circumferentially provided inside the sealing pressure plate 6, and an external threaded wall 10 is circumferentially provided outside the discharge pipe 3 facing the internal threaded wall 11. As Figure 4 shown, the external threaded wall 10 is in threaded engagement with the internal threaded wall 11. The discharge pipe 3 can be rotated from the external threaded wall 10 to the outside of the internal threaded wall 11 by rotation. Through the threaded engagement, the discharge pipe 3 can be fixed inside the sealing pressure plate 6. Similarly, the disassembly and replacement of the discharge pipe 3 can be achieved by rotating the discharge pipe 3;

[0025] In this embodiment, as Figure 4 shown, a sealing ring 9 (the sealing ring 9 is packing or sealing filler or rubber material) is circumferentially provided inside the installation cavity 12, and the sealing ring 9 is located between the discharge pipe 3 and the sealing sleeve 2. The gap between the discharge pipe 3 and the sealing sleeve 2 can be sealed by the sealing ring 9;

[0026] In this embodiment, first filling blocks 4 are provided on both sides of the sealing pressure plate 6, and second filling blocks 5 are provided at both ends of the sealing pressure plate 6. The second filling blocks 5 and the first filling blocks 4 are both welded and fixed to the feed box 1. As Figure 2 and Figure 3 shown, a first converging inclined surface 13 is inclined towards the sealing pressure plate 6 on the outside of the first filling block 4, and a second converging inclined surface 14 is inclined towards the sealing pressure plate 6 on the outside of the second filling block 5. The inclined first converging inclined surface 13 and the second converging inclined surface 14 can guide the pulp poured from the upper end of the feed box 1, and guide and make the pulp flow towards the discharge pipe 3.

[0027] Working principle: When using the device to buffer the transmission of the transported pulp, after the pulp falls into the feed box 1, the first filling blocks 4 and the second filling blocks 5 on both sides inside the feed box 1 limit the transported pulp. The first converging inclined surface 13 on the surface of the first filling block 4 and the second converging inclined surface 14 on the surface of the second filling block 5 can converge the pulp, making the pulp continuously flow towards the discharge pipe 3. The converged pulp is discharged from the discharge port 15 inside the discharge pipe 3. When replacing the discharge pipe 3 that has been rubbed for a long time, pull the lifting lug 7. By pulling the lifting lug 7, the sealing pressure plate 6 and the thread-connected discharge pipe 3 can be longitudinally moved upward. After driving the discharge pipe 3 out of the feed box 1, rotate the discharge pipe 3. After the discharge pipe 3 rotates, the discharge pipe 3 can be taken out of the sealing pressure plate 6. After replacing the discharge pipe 3, the external threaded wall 10 on the surface of the discharge pipe 3 is in threaded engagement with the internal threaded wall 11 inside the sealing pressure plate 6 to fix the new discharge pipe 3. Finally, hang the lifting lug 7 to make the lifting lug 7 drive the discharge pipe 3 fixed at the lower end to be embedded inside the installation cavity 12. After embedding, when the sealing pressure plate 6 contacts the lower end of the inner wall of the feed box 1, the position of the discharge pipe 3 is fixed, thereby realizing the assembly, disassembly and replacement of the discharge pipe 3.
