Description
Technical field
The present invention relates to vacuum filter technical fields, specifically, being related to a kind of double vacuum filter drains of disc type
Device.
Background technology
Disc type filter is the vacuum filter for forming several filtering disks in a horizontal blank mandrel
Referred to as disc type filter.It filters power and also comes from pressure difference caused by vacuum.If each disk is divided into
Dry small sector filter leaf, each sector filter leaf constitute a filter chamber, it is small suitable for filter densities, is not easy to precipitate
Suspension.Single vacuum filter under the prior art is found that problems in long-term production and practice process：
1) it is connected to the areas Tuo Gan due to adsorption zone, air is in direct contact outside the areas Tuo Gan filter fan, since the areas Tuo Gan are filtered
Fan inside and outside differential pressure causes air to enter inside the areas Tuo Gan filter fan, to cause the vacuum of the whole system including adsorption zone to drop
It is low so that entire filtration system is difficult to reach higher vacuum values (while also resulting in energy waste) filtered material also just
It is difficult to realize lower moisture content；
2) it when filter has changed filter cloth bag and started to work, since the areas Tuo Gan lead directly to air, is inhaled not yet outside filter cloth bag
It is attached to material, a large amount of gas directly pours in filter fan, causes the very slow of the vacuum up of whole system.With system
The raising of interior vacuum degree, the suction ore bed for inhaling mining area are gradually thickening, are moving in circles so generally according to the difference of material, need to disappear
Longer time is consumed, the vacuum values in system could be made to reach normal working condition.And during this period of time filter cake moisture
Equipment performance index is not achieved, is defective work, this slow process is to cause a large amount of wastes of the energy, and produce
A large amount of materials that moisture content severely exceeds cause to seriously affect to downstream production.
In view of above-mentioned technical problem existing for single vacuum filter under the prior art, it is proposed that a kind of new disc type is double
Vacuum filter, double vacuum systems-refer to corresponding to the filter fan operation in adsorption zone and the areas Tuo Gan respectively by two vacuum pumps.Inhale
Attached area, the areas Tuo Gan respectively become an independent vacuum system.The vacuum of adsorption pump output does not waste, and makes the filter fan of adsorption zone
Form the filter cake of maximum gauge.After filter fan enters the areas Tuo Gan, under the action of de- dry pump, de- dry systems can be made to reach a phase
The material moisture by being filtered dry can be made to reduce by 1/10 or so than the material moisture content that single vacuum filter is filtered dry higher vacuum values.
To be provided a convenient for downstream production.On the other hand, the double vacuum filters of disc type increase substantially the qualification rate of filter material,
Reduce energy consumption.Compared with single vacuum filter under the prior art, the advantage high with vacuum degree, filter cake moisture is low.
However, the double vacuum filters of the disc type proposed under the prior art, which still have, need to be arranged two sets of vacuum systems and gravity
Drainage system, two sets of vacuum systems and gravity drainage system occupied space and place at the construction field (site), and due to needing to exist
The more flashback tanks of bottom of device setting are more, need in addition to design drainage system and increase drainage arrangement to cope with drainage problem.
In view of this, should be improved to the double vacuum filters of disc type in the prior art, to solve in the prior art
Existing above-mentioned technical problem.
Invention content
In order to solve the above-mentioned technical problem the present invention makes, the purpose is to provide a kind of structure simplification, be not necessarily to
Construction site occupies more construction area, and can effectively reduce maintenance times in the long-term use, reduces and safeguards
The double vacuum filter pumping equipments of the disc type of cost.
To achieve the goals above, the present invention provides a kind of double vacuum filter pumping equipments of disc type, which includes：
Drain tank body, the drain tank body are set to above the ground according to preset height, and are supported and fixed by pedestal, below the pedestal
It is provided with flashback tank；Inlet flange, the inlet flange are set to the middle part of the drain tank body, the inlet flange be used for it is double
Vacuum filter connects；Vacuum flange, the vacuum flange are set to the top of the drain tank body, the vacuum flange be used for
Vacuum pump connects；Discharge flange, the discharge flange are set to the bottom of the drain tank body, the discharge flange by water pipe with
The flashback tank connection.
Preferably, the preset height can be in the range of 10m to 15m.
Preferably, it may include four inlet flanges, two vacuum flanges and two discharge flanges.
Preferably, partition board can be provided in the Drainage tank body, the partition board can will separate in the Drainage tank body
At symmetrical two vacuum areas.
It is further preferred that described device can also include two pressure relief valves, described in each pressure relief valve and one
Vacuum area corresponds to, and the vacuum degree in the vacuum area is adjusted by switching the pressure relief valve.
Further preferably, described device can also include two vacuscope dial plates, and each vacuscope dial plate can be with
It is corresponding with a vacuum area, in this way, can be obtained by the vacuscope dial plate true in the current vacuum region
Reciprocal of duty cycle.
Preferably, the inlet flange can be formed with difference in height in vertical direction with double vacuum filters.
Pass through as described above it is found that in the double vacuum filter pumping equipments of disc type of the present invention with practice
Drain tank body is set in the height on 10 meters of distance construction ground by pedestal so that there are one for drain tank body and the flashback tank of bottom
Fixed difference in height；Symmetrical two vacuum areas are separated by partition board in Drainage tank body, correspond to the double vacuum filters of disc type respectively
Pulp absorbing area in machine and drying zone when construction, observe the vacuum degree in two vacuum areas, and by letting out by vacuscope dial plate
It is poor that there are vacuum in pressure valve two vacuum areas of holding, and double vacuum mistakes structurally and operationally can be realized using what is more simplified in this way
The moisture that filter pulp absorbing area and drying zone filter out is discharged from the flange in different vacuum areas；After filtering, water seal is connected
Ore pulp in the water pipe of case and drain tank body returns in flashback tank again, and out of double vacuum filter pulp absorbing areas and drying zone
The moisture of filtering is also drained into from drain tank body in flashback tank.In conclusion the double vacuum filter rows of disc type of the present invention
Liquid device is directly connect with the double vacuum filters of disc type and vacuum pump, is saved significantly using more simplified structure at the construction field (site)
It has saved and has completed the construction area that the equipment needed for dewatering work occupies at the construction field (site)；Also, by observing vacuscope dial plate simultaneously
The operation relatively simple in this way of adjusting pressure release valve door, which can be realized, keeps the vacuum in Drainage tank body in SYMMETRIC VACUUM region poor, most
Afterwards, after the completion of filtering, liquid and moisture in pipeline can be back in flashback tank again, and it is right in dewatering work to greatly reduce
The maintenance times of equipment while improving dehydration efficiency, also extend the service life of device entirety.
