Problems solved by technology

The sedimentation and separation operation of this equipment is mainly completed in the inclined shallow sedimentation module. When the equipment is enlarged, dozens of modules need to be combined into one equipment, and the feeding material of the equipment is only 2-4 points, which cannot make the ore slurry Evenly distributed to the corresponding settlement modules, resulting in inconsistent working status of each settlement module, affecting the effective performance and stable operation of equipment performance

Embodiment 1

[0042] In a polymetallic sulfide ore dressing plant, ZXN-500 vibrating inclined plate settlement thickener is used for unilateral ore feeding. In the concentration of the middle ore after tin selection, use a ZXN-500 vibrating sloping plate oblique shallow layer thickener for concentration. The equipment has a total of 10 inclined plate settling modules, two cone buckets discharge underflow, and uses a set of uniform feeding device of the present invention.

[0043] In the first-stage feeding unit 100, the shape of the feeding box 101 is a cuboid, and its length, width and height are 1000×500×1200mm. The interior is divided into sieve-type slag separators 102 by partitions of different heights. , the middle tank 105 and the ore-distributing channel 107. The length, width and height of the sieve-type slag separator 102 are 500×500×1000 mm, which is a complete through trough, and no isolation is required inside; the length, width and height of the middle tank 105 are 800×500×60...

Embodiment 2

[0048] In an iron ore concentrator, a ZXN-2400 vibration-type oblique box oblique shallow layer thickener is used to concentrate the fine-grained ore pulp in the tailings dry-drainage and heap concentration. The equipment has a total of 48 inclined box settling modules, eight cone buckets discharge the underflow, and two sets of uniform feeding devices with half-type slag separators of the present invention are used.

[0049] In the first-stage feeding unit 100, the shape of the ore feeding box 101 is a cuboid, and the length, width, and height dimensions are 1000×500×1200 mm. Sieve-type slag separator 102, in which wear-resistant material boards are laid to prevent the impact of ore pulp; outside the sieve-type slag separator 102, a middle tank 105 with a length, width and height of 800×500×600mm is set outside the middle tank 105 There is a mine-dividing channel 107 whose length, width and height are 1000×500×600mm. The sieve-type half-type slag separator 102 is made of wea...

Embodiment 3

[0054] An iron ore dressing plant contains a certain amount of phosphate ore, and the slurry needs to be concentrated and deslimed before the iron ore tailings are selected for phosphorus. A ZXN-1200 vibrating inclined box inclined shallow layer thickener is used to deslim the fine-grained ore pulp. The equipment has a total of 24 inclined box settling modules, four cone buckets discharge the underflow, and uses a set of uniform feeding device of the present invention.

[0055] In the first stage feeding unit 100, the profile of the ore feeding box 101 is a cylinder, and the external dimensions of a single device are Set the diameter at the middle position inside the mine box 101 to A sieve-type slag trap 102 with a height of 1200 mm. The sieve-type slag trap 102 is composed of two semicircular half-shaped slag traps 1021. The half-shaped slag trap is made of PE pipes. 103 and the bottom is opened with a diameter of hole. Outside the sieve type slag separator 102, the di...

Abstract

The invention belongs to the technical field of mineral processing and relates to an oblique shallow settlement thickener uniform feeding device with half-type residue separators. The oblique shallowsettlement thickener uniform feeding device comprises two stages of or more feeding units, the ore pulp of the previous stage of feeding unit enters the next stage of feeding units through two or morefeeding points, the feeding unit connected with the settlement module of an oblique shallow settlement thickener is provided with a plurality feeding points used for guiding the ore pulp into the appointed ore feeding area of the settlement module of the oblique shallow settlement thickener, and the feeding points of the feeding unit connected with the settlement module of the oblique shallow settlement thickener are set according to the hole number of the settlement module; one feeding unit of the uniform feeding device is provided with a sieve pore type residue separator formed by combiningtwo half-type residue separators, and the sieve pore type residue separator receives the ore pulp entering the uniform feeding device and is used for dissipating energy and retaining coarse residuesand impurities in the ore pulp. The uniform feeding device can solve the uniform distribution problem of the thickener through multi-point feeding.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and relates to feeding materials for an oblique shallow sedimentation thickener, in particular to a uniform feeding device for an oblique shallow sedimentation thickener with a half-type slag separator. Background technique [0002] Inclined shallow sedimentation thickeners include inclined plate thickeners, inclined tube thickeners and inclined box thickeners, which are divided into vibration type and static type according to whether the settlement module moves or not. Due to the advantages of small footprint, high sedimentation efficiency, and low energy consumption, the equipment has been widely used in solid-liquid separation operations and coarse and fine-grained desliming operations in mineral processing and beneficiation plants. The sedimentation and separation operation of this equipment is mainly completed in the inclined shallow sedimentation module. When the equipment is enl...
