Description
Technical field
The utility model belongs to the pipeline transportation field, relates to pulp dewatering technology, particularly relates to a kind of dewatering system that improves the ceramic filter production capacity.
Background technology
Ceramic filter is a kind of solid-liquid separating equipment of novel high-efficiency and energy-saving, and collection micropore ceramics, machine-building, ultrasonic wave clean, the micro computer controlled one that is formed on, and adopt micropore ceramics to make filter medium, use the capillary effect principle and carry out Separation of Solid and Liquid.
When pipeline is normally carried, there is the compound of iron such as the free iron ion of a small part, ferrous hydroxide, di-iron trioxide in the iron ore concentrate ore pulp.Along with selecting factory's technique change, the content of this part compound is increasing.Disclose existing ore pulp characteristic production technology just often among Fig. 1, ore pulp directly enters the distribution bucket by valve behind the incoming terminal dehydrating plant, be assigned to 8 ceramic filters and carry out Separation of Solid and Liquid.Ore pulp that ceramic filter overflows and water for cleaning enter the concentration basin precipitation by overflow pipe, are beating by the underflow pump to distributing bucket to improve the total concentration of ore pulp after the raising concentration.In long-time Separation of Solid and Liquid process, excessive iron compound adsorbs or is deposited on ceramic filter plate surface and ceramic filter plate micropore, can cause that the ceramic filter plate micropore stops up, and influences the ceramic filter plate production capacity.
The pulp granularity that pipeline is carried is generally-325 orders about 68%, 100 orders about 93%, but if pumping plant stops midway, ore pulp is sedimentation in pipeline, restart the back and form in the pipeline fine grained preceding, coarse granule after the unbalanced situation of ratio.After a large amount of fine grain ore pulps enter ceramic filter, cause that the ceramic filter plate micropore stops up, degradation problem under the cleaning performance, cause ceramic filter output to send the ore deposit amount less than pipeline, and this obstruction needs long cleaning frequency or change ceramic filter plate and could recover, and is bigger to later stage production and cost impact.
The utility model content
The purpose of this utility model is to provide a kind of ceramic filter dewatering system, can improve the filtration coefficient of ceramic filter when changing appears in the ore pulp characteristic.
The utility model specifically discloses a kind of ceramic filter dewatering system, comprise: distribute bucket, ceramic filter, concentration basin, accident pool, underflow pump and overflow pipe, ceramic filter is arranged on the dehydration workshop, distribute bucket to be connected to ore slurry pipeline by distributing valve, be used for ore pulp is assigned to ceramic filter, overflow pipe is communicated with ceramic filter and concentration basin, the ore pulp and the water for cleaning that are used for ceramic filter is overflowed are sent into the concentration basin precipitation, also comprise a pipeline that is connected to concentration basin by ore slurry pipeline, this pipeline is controlled by concentrated valve, is used for that ore pulp is redistributed to ceramic filter after concentration basin concentrates and carries out Separation of Solid and Liquid.
Further, the ore pulp after described underflow pump is used for concentration basin concentrated is beaten to distributing bucket.
Further, also comprise cesspool and sewage pump, cesspool is linked accident pool by sewage pump, and accident pool is communicated to overflow pipe by a pipeline.
Adopt system of the present utility model to carry out dewatering process compared with prior art, have following beneficial effect:
Because the utility model by precipitation, overflow to ore pulp, has improved the production capacity of ceramic filter.
Because the utility model has avoided ceramic filter plate to stop up in a large number by precipitation, overflow to ore pulp, influence production for a long time and increase condition of cost.

The specific embodiment
Below in conjunction with Fig. 1-4, the utility model is described further.
Fig. 2 shows the ceramic filter dewatering system that the utility model provides, on the basis of prior art shown in Figure 1, increase the sewage conduct that is connected to accident pool 6 from underflow pump house 12 interior sewage pumps 9 among Fig. 2 newly, be used for concentration basin 1 overflow water and squeeze into accident pool 6 precipitations.Accident pool 6 backs increase slag stock pump 10 and accident pool ore pulp pipe 14 newly, are communicated with accident pool to overflow pipe 5, are used between turn(a)round, and the fine grained ore deposit of precipitating in the accident pool adds to be beaten to concentration basin 1 after water stirs, and reenters 11 dehydrations of dehydration workshop.
Shown in Fig. 3 is ore pulp characteristic production technology just often.Ore pulp distributes valve 7 directly to enter by the dehydration workshop and distributes bucket 3, carry out Separation of Solid and Liquid by 8 ceramic filters 4 that distribute bucket 3 to be assigned in the dehydration workshop 11 then behind the incoming terminal dehydrating plant.Ore pulp that ceramic filter 4 overflows and water for cleaning enter concentration basin 1 precipitation by overflow pipe 5, pass through 2 dozens of total concentration to distribution bucket 3 raising ore pulps of underflow pump after the raising concentration again.The ore pulp characteristic just often, fine grained ore deposit ratio is little in the ore pulp, do not influence ceramic filter 4 production capacities, and the overflow water mine-containing amount of concentration basin is less, carries out 3 grades of overflows by accident pool 6, enters gravity filter and filters and squeeze into elder brother's steelpipe net.
The ore pulp characteristic back ceramic filter dehydrating process that changes is disclosed among Fig. 4.After the ore pulp characteristic changes, open and concentrate valve 13, close the dehydration workshop and distribute valve 7, after pipeline was delivered to the terminal dehydrating plant, ore pulp directly entered concentration basin 1 after concentrating valve 13, by concentration basin 1 precipitate, overflow.Smart iron ore is because of the difference proportion difference of granularity thickness, coarse grained concentration basin 1 bottom that is precipitated to, treat that concentration is brought up to a certain degree after, dewater to distributing bucket 3 to enter dehydration workshop 11 by 2 dozens of 2 underflow pumps.Smart iron ore that particle is thinner in the concentration basin 1 and the iron compound in the ore pulp can swim in water surface upper strata because of proportion is less the short time, by increasing the inflow of concentration basin 1, swim in the smart iron ore of fine grained on water surface upper strata and iron compound overflow to cesspool 8, precipitate by 9 dozens of sewage pumps to accident pool 6.When treating that pipeline stops conveying or carries out overhaul of the equipments, empty the fine grained ore deposit that the water in the accident pool 6 precipitates in spilling the pond, add and get to concentration basin 1 precipitation by slag stock pump 10 and accident pool ore pulp pipe 14 after ore pulp is made in a spot of water stirring, after concentration is brought up to a certain degree, enter dehydration workshop 11 by 2 dozens of 2 underflow pumps to distribution bucket 3 and dewater again, guarantee that the iron ore concentrate that is transported to all dewaters.
This method of operating purpose is that pipeline is during sending the ore deposit continuously, separate by the thickness particle in 1 pair of ore pulp of concentration basin, coarse grained ratio improves production capacity when increasing pulp dewatering, treating to dewater again when pipeline stops conveying or maintenance in fine grain ore deposit, thereby guarantees the production capacity when sending the ore deposit continuously again.
After the ore pulp characteristic variations, as dewatering according to normal condition, the ceramic filter chance is stopped up because of a large amount of ceramic wafers, and production capacity drops to 150t/h.By dehydrating process of the present utility model, can avoid ceramic wafer to stop up, can recover production capacity to 350t/h, improved the production capacity of ceramic filter under the complex situations greatly.
