Description

Technical Field

[0001] The utility model relates to the technical field of ore slurry pipelines for mineral processing, and more specifically to a slurry inlet pipe for a slurry pump used in a mineral processing plant. Background Art

[0002] The slurry pump inlet pipe of the mineral processing plant is the only connecting pipe between the slurry pump pool and the slurry pump, which plays the role of conveying the slurry. Because the mineral processing plant process mostly adopts high-concentration flotation, the slurry solids account for a large proportion, the foam viscosity is large, the water quality pH is mostly alkaline, and the flotation conditions also need to reach high alkalinity. The pH value is adjusted by lime. Therefore, the slurry is very easy to form calcium, and the slurry pump inlet pipe is often blocked by precipitation, which requires frequent cleaning and dredging.

[0003] When cleaning a clogged slurry pump inlet pipe or repairing the pump body, workers generally need to dismantle the connecting structures at both ends of the slurry inlet pipe, clean the pipe, and then reinstall the slurry inlet pipe. This method of removing the pipe is time-consuming and labor-intensive, thereby reducing the maintenance efficiency of the slurry inlet pipe. Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems and provide a slurry inlet pipe for a slurry pump used in a mineral processing plant, which can conveniently and quickly clear the pipeline and improve the maintenance efficiency of the slurry inlet pipeline.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical scheme: a slurry inlet pipe of a slurry pump for a mineral processing plant, comprising a pump pool and a slurry pump, the slurry outlet of the pump pool is fixedly provided with a slurry outlet pipe, the slurry inlet of the slurry pump is fixedly provided with a slurry inlet pipe, the inner side movable sleeve of the slurry outlet pipe is provided with a connecting pipe, a pressure cover is installed between the slurry outlet pipe and the connecting pipe, and one end of the connecting pipe located outside the slurry outlet pipe is detachably connected to the slurry inlet of the slurry inlet pipe.

[0006] In order to fix the position of the pressure cover, as a preferred embodiment of the utility model for a slurry inlet pipe of a slurry pump for a mineral processing plant, a first flange is fixedly arranged at one end of the slurry outlet pipe away from the pump pool, and the pressure cover includes a movable pipe and a second flange, the movable pipe is movably connected to the inner wall of the slurry outlet pipe, and the first flange and the second flange are detachably connected by bolts.

[0007] In order to limit the position of the connecting pipe, as a preferred slurry inlet pipe of a slurry pump for a mineral processing plant of the utility model, a retaining ring is fixedly provided at one end of the connecting pipe located inside the slurry outlet pipe, and the outer diameter of the retaining ring is larger than the inner diameter of the moving pipe.

[0008] In order to improve the sealing performance of the entire pipeline, as a preferred embodiment of the utility model of a slurry inlet pipe of a slurry pump for a mineral processing plant, a packing is movably arranged between the retaining ring and the movable pipe.

[0009] In order to facilitate the disassembly of the connecting pipe, as a preferred slurry inlet pipe of a slurry pump for a mineral processing plant of the utility model, a third flange is fixedly provided at one end of the connecting pipe located outside the slurry outlet pipe, and a fourth flange is fixedly provided at the slurry inlet of the slurry inlet pipe, and the third flange and the fourth flange are detachably connected by bolts.

[0010] The beneficial effects of the utility model are as follows: by dividing the slurry inlet pipeline into three pipeline parts, namely the slurry outlet pipe, the connecting pipe, and the slurry inlet pipe, the slurry outlet pipe is connected to the pump pool, the slurry inlet pipe is connected to the slurry pump, the connecting pipe part is inserted into the slurry outlet pipe, and the two sections of the pipeline are a nested structure. When repairing the blocked pipeline, the bolts of the connecting pipe port flange can be removed to make it expand and contract, thereby providing a relatively open space for the staff to repair, thereby achieving the effect of quickly unblocking the pipeline, saving maintenance time, and reducing labor intensity.

[0019] In this embodiment: one end of the connecting pipe 5 is nested with the slurry discharge pipe 2, and the other end of the connecting pipe 5 is detachably connected to the slurry inlet pipe 6. When the entire slurry inlet pipeline is blocked, the connection between the connecting pipe 5 and the slurry inlet pipe 6 is disassembled, and the connecting pipe 5 is pushed into the inner side of the slurry discharge pipe 2. At this time, the two pipelines overlap and a large gap is left between the slurry discharge pipe 2 and the slurry inlet pipe 6, which can facilitate the staff to clean or repair the blocked part of the pipeline through the gap; by installing the pressure cap 3 between the connecting pipe 5 and the slurry discharge pipe 2, the position of the pressure cap 3 is fixed, and a retaining ring 501 is fixed at one end of the connecting pipe 5 located inside the slurry discharge pipe 2, and the outer diameter of the retaining ring 501 is larger than the inner diameter of the movable pipe 301, so that the pressure cap 3 has a limiting effect on the retaining ring 501, and the pressure cap 3 also has a sealing effect on the gap between the slurry discharge pipe 2 and the connecting pipe 5.

[0020] As a technical optimization solution of the present invention, a packing 4 is movably provided between the retaining ring 501 and the moving tube 301 .

[0021] In this embodiment: a packing 4 is arranged between the gland 3 and the retaining ring 501. The gland 3 compresses the packing 4 to fix its position. The packing 4 is made of a flexible material and seals the gap between the slurry outlet pipe 2 and the connecting pipe 5 through the extrusion of the moving pipe 301 and the retaining ring 501, thereby improving the sealing performance of the overall slurry inlet pipeline.

[0022] The working principle and use process of this utility model:

[0023] (1) When installing the integral pipeline, one end of the connecting pipe 5 is nested with the slurry outlet pipe 2, and the third flange 502 and the fourth flange 601 at the other end of the connecting pipe 5 are detachably connected by bolts, and then the packing 4 is placed in the gap between the connecting pipe 5 and the slurry outlet pipe 2, and then the gland 3 is pressed into the gap between the connecting pipe 5 and the slurry outlet pipe 2. At this time, the moving pipe 301 and the retaining ring 501 squeeze the packing 4 to form a sealing ring, and finally the first flange 201 and the second flange 302 are detachably connected by bolts, and then the position of the gland 3 is fixed, thereby completing the installation of the slurry inlet pipeline;

[0024] (2) When repairing a blocked pipeline, remove the connecting bolts of the third flange 502 and the fourth flange 601, and then push the connecting pipe 5 into the inner side of the slurry outlet pipe 2, so as to leave a large gap between the slurry outlet pipe 2 and the slurry inlet pipe 6, so that the staff can clean or repair the blocked part of the pipeline through the gap.

[0025] (3) When disassembling the slurry inlet pipeline, remove the connecting bolts between the first flange 201 and the second flange 302, then take out the packing 4, and then remove the connecting bolts between the third flange 502 and the fourth flange 601, and take out the connecting pipe 5 from the gap between the slurry outlet pipe 2 and the slurry inlet pipe 6, so as to replace the damaged slurry inlet pipeline.
