Abstract
The utility model discloses a heavy medium coal-separating and scavenging and tail coal-magnetic separating parallel device which comprises a coal slime heavy medium processing device, a tail coal scavenging and concentrating device, a scavenging and magnetic separating device and a medium waste rock magnetic separating device, wherein discharge ends of the coal slime heavy medium processing device and the tail coal scavenging and concentrating device are connected with the same charge pipe, and a discharge end of the charge pipe is respectively communicated with charge ends of the scavenging and magnetic separating device and the medium waste rock magnetic separating device by a pipeline. The iron powder content and the coal slime content in the material processed by the parallel device are proper, the magnetic separating efficiency is greatly improved, the magnetic separating device plays a part in proper function, the magnetic separating efficiency of the tail coal magnetic separation is improved, the magnet mineral powder lost in the tail coal is obviously reduced, the loss of the magnet mineral powder in the whole production system is reduced, and the production cost is reduced.
Description
Technical field
The utility model belongs to that the magnetite powder recycle device, particularly heavy media coal separation that use in the operation of coal washing processing heavy media coal separation are scanned, tail coal magnetic separation shunting means.
Background technology
In recent years, raising along with raw coal mine main mining depth and mechanization production degree, raw coal quality general trend variation, user and environment are more and more higher to the requirement of Coal Quality in addition, the heavy media coal separation technology reaches its maturity, and most of coal preparation plants newly-built or reconstruction have all adopted part heavily to be situated between or full weight Jie coal preparation technique.The hm coal preparation plant dielectric loss is an important index, the consumption that is situated between height is the important technology economic indicator that hm coal preparation plant is weighed full factory production technology level and managerial skills, dielectric dissipation is excessive, not only cause the loss of medium, polluted product, reduce product quality, cause loss economically, but also influence the normal, stable of heavily Jie system production.Thereby adding medium in the heavy media coal separation system---magnetite powder is recycle and reuse as far as possible.And that medium reclaims is directly related with the efficient and the technology of magnetic separator, and the efficient of magnetic separator is relevant with the size of pan feeding flow, concentration, granularity, slime content and mine tailing spillway discharge etc. again.Therefore, improve the magnetic separator efficiency of magnetic separation, reducing magnetite powder consumption is the emphasis and the difficult point of heavy media coal separation technology.The intrinsic technology of scanning magnetic separator of existing dense media system's concentration equipment is to reclaim the contained magnetite powder of flotation device mine tailing, wherein magnetite powder content seldom, only account for 8-10%, fine size, and the content of coal slime and water is very big, to the annoyance level height of magnetic separator, efficiency of magnetic separation is very low, scans magnetic separator and does not bring into play due effect; And the technology of tail coal magnetic separator is the magnetite powder in coal in reclaiming, the rare medium of spoil, wherein magnetite powder content is big, total solids concentration is big, and granularity is big, and flow is few, in the actual production, often cause in the magnetic tailing the iron powder of being with many, the magnetic thing rate of recovery is lower, makes that whole system technology dielectric loss is higher, also cause the stifled pressure of next process procedure-section inclined tube concentration basin simultaneously easily, influence ordinary production.
Summary of the invention
The purpose of this utility model is to provide that a kind of heavy media coal separation is scanned, tail coal magnetic separation shunting means, and it is simple in structure, can improve efficiency of magnetic separation effectively, reduces magnetite powder consumption, reduces production costs.
The purpose of this utility model is to realize like this, a kind of heavy media coal separation is scanned, tail coal magnetic separation shunting means, comprise coal slime heavily be situated between treating apparatus, mine tailing scan the concentration device, scan concentration equipment and in, the cash concentration equipment, heavily be situated between treating apparatus and mine tailing of coal slime scanned the two discharge end of concentration device and all linked to each other with same feed pipe, the discharge end of this feed pipe respectively by pipeline with said scan concentration equipment and in, the two feed end of cash concentration equipment is connected.
The utility model device is incorporated into one to the material that originally advances two magnetic separators respectively earlier, mean allocation is given two magnetic separators again, thereby the material that has guaranteed to advance two magnetic separators all is in adapting in flow, concentration, granularity, slime content, magnetite powder amount, can both satisfy the characteristic requirement of magnetic separator to material.Iron content, coal slurry content that this shunting means is handled in the material are moderate, efficiency of magnetic separation improves greatly, not only magnetic separator has played due effect, tail coal magnetic separator efficiency of magnetic separation also increases, the magnetite powder that loses obviously lowers in the mine tailing, and the magnetite powder loss reduces in the whole production system, has reduced the cost of production and processing.Through on probation, adopt the utility model device, the magnetic separator tailing zone is situated between and was reduced to 0.37g/L by former 0.62g/L.Produce the consumption that is situated between and be reduced to 2.1kg/ ton raw coal by present 2.6kg/ ton raw coal.Direct economic benefit can reach 1,740,000 yuan/year.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a syndeton block diagram of the present utility model.
The specific embodiment
A kind of heavy media coal separation is scanned, tail coal magnetic separation shunting means, as shown in Figure 1, comprise coal slime heavily be situated between treating apparatus 4, mine tailing scan concentration device 1, scan concentration equipment 2 and in, cash concentration equipment 3, heavily be situated between treating apparatus 4 and mine tailing of coal slime scanned the two discharge end of concentration device 1 and all linked to each other with same feed pipe, the discharge end of this feed pipe respectively by pipeline with said scan concentration equipment 2 and in, the two feed end of cash concentration equipment 3 is connected.Like this, material in this feed pipe is through after mixing, can guarantee that into the material of two magnetic separators all is in the adaptation in flow, concentration, granularity, slime content, magnetite powder amount, make efficiency of magnetic separation improve greatly, not only magnetic separator has played due effect, and tail coal magnetic separator efficiency of magnetic separation also increases, and the magnetite powder that loses obviously lowers in the mine tailing, and the magnetite powder loss reduces in the whole production system, has reduced the cost of production and processing.
