Specific implementation mode
The utility model is described further with reference to specific embodiments and the drawings, to help the utility model is understood
Content.
As shown in Figure 1, being that a kind of structure of the emulsion backwash filter device of cold-strip steel provided by the utility model is shown
It is intended to.The emulsion backwash filter device of the cold-strip steel includes shell, and the enclosure interior is equipped with central shaft 11 and ring
Several filter cores 15 being distributed around central shaft 11, the filter core 15 are the cylindrical cartridge of both ends open.Preferably, the both ends open
Cylindrical cartridge be longitudinal plus wedge wire rope net surface filter core.11 upper end of the central shaft, which is connected with, rotates lid arm 2, under the central shaft 11
End is connected with rinse arm 1, and the case top is equipped with driving device, couples with central shaft 11, is used for the rotation of control centre's axis 11.
Preferably, the driving device is gear motor 10.The upper part of the housing is equipped with filtrate (liquid 17, and the lower part of the housing is equipped with filter
Liquid import, the filtrate import are connected to the filter core 15.Preferably, the filtrate import is equipped with suction flange 3.The shell
Bottom is equipped with the sewage draining exit 13 being connect with residual cake valve 12, and the housing bottom is additionally provided with fixed frame 16.The hull outside is equipped with
Differential pressure controller.Preferably, the differential pressure controller is differential pressure transmitter device 9.
As shown in figure 3, being a kind of filtering system of the emulsion backwash filter device of cold-strip steel provided by the utility model
System structural schematic diagram.Filtered model is：Liquid to be filtered through suction flange 3 enter filter bottom, about 50% it is to be filtered
Liquid enters the top of filter, the upper end opening still further below through filtration core top 5 through intermediate tedge 4；One in bottom
Half liquid to be filtered passes upward through the lower ending opening of filter core lower part 6.Liquid to be filtered is after filter core gap 7 is filtered from filtrate (liquid
17 outflows, filter core gap 7 can reach 30 microns.
As shown in Fig. 2, being a kind of backwash of the emulsion backwash filter device of cold-strip steel provided by the utility model
System structure diagram.Backwash mode is：In backwash, filter core 15 is cleaned one by one, but is not interrupted
The operation of filtering process.Filtered net liquid 8 prevents the top of filter core 15 from blocking.The energy of backwash can come from filter and go out
Mouthful, it is determined by the operating pressure of whole device.Backwash by filter inlet outlet pressure differential (differential pressure controller) or by
Revisable time interval triggers.Preferably, the differential pressure controller is differential pressure transmitter device 9.When just starting filtering, mistake
The filter core cavity pressure of filter is held essentially constant, and liquid to be filtered is flowed outwardly from the inner cavity of filter core 15, with filter process
It carries out, entrained solid impurity is trapped within the inner surface of filter core 15, and interior exocoel pressure difference is caused to increase, and filtration resistance gradually increases
Greatly, when pressure difference increases to the setting value of differential pressure transmitter device 9, differential pressure transmitter device 9 sends out signal, controls electric motor starting, drives
Driving device is run, and the operating of driving device carry backwash system rinses the inner cavity of entire filter core 15 well, to ensure to filter
The normal operation of device.While cleaning, residual cake valve 12 is opened, and the dirt rinsed is discharged from sewage draining exit 13.Pressure difference is sent out
The setting value of news device 9 can be adjusted according to actual needs.
As shown in figure 4, being a kind of filter core mistake of the emulsion backwash filter device of cold-strip steel provided by the utility model
Filter stage and backwash stage schematic diagram and flushing speed effect figure.Liquid to be filtered is flowed into from 15 both ends of filter core.Pass through this
Kind mode, filtered impurity particle will remain in the whole length section of filter core 15, to make entire filtration zone obtain
It makes full use of.When remain in the impurity in filter core 15 reach need clean amount when, backwashing system starts automatically.Electric motor starting
Backwashing system, the rotation lid arm 2 above filter core 15 start to rotate, the upper end opening of filter core 15 are covered；At the same time,
Lower section rinse arm 1 rotates, and residual cake valve 12 is opened when reaching the position of 15 lower ending opening of corresponding filter core.In this way, in filter core 15
Portion will form a set of high speed axial direction current system.On the other hand, generated barometric gradient only allows less amount of liquid logical
It crosses, from reverse reflux above filter core 15.Rotary barrel throttle 14 with PTFE cover boards is located at the top of filter core 15, forms the cross of deceleration
To the backwash of flowing, backwash energy is made to be evenly distributed in the whole length section of filter core 15.Vertical and horizontal backwash
It acts on simultaneously, makes the whole length section equilibrium cleaning of filter core 15, to reach best backwash effect.
The utility model has the function of being filtered to former emulsion and carry out cleaning blowdown to filter core automatically, and cleans
System is uninterruptedly for emulsion when blowdown.Compared with existing filter, the automation degree of equipment is high, and treating capacity is big, can be voluntarily
Blowdown is cleaned, cleaning speed is fast, and intensity is big, and cleanliness factor is high, and can realize uninterruptedly for emulsion have a wide range of application.In addition, also
Operating cost can be reduced, the generation of the phenomenon of leakage is prevented.
The cylindrical cartridge that the utility model uses has bipolar function, effective backwashing system can be with for both ends open
Filter core is prevented gradually to be blocked, the frequency for replacing filter core is smaller than the frequency of taper and other cylindrical cartridges, can both save in this way
Manpower, and the consuming cost of part can be reduced.The utility model uses the cylindrical cartridge of both ends open, than the filter for extending disc type
The mode that core detaches solid is more reliable.Because can deposit impurity particle between extension disk, this is dangerous, and when backwash
When program is switched to filter, the particle of these siltations will be blended back into original clean liquid, so that defined mistake
Filter precision is not easy to reach.The filter core of the utility model is designed as longitudinal plus wedge shape arrangement, compared with taper and extension disc type filter core,
For impurity particle, especially fiber grain, splendid cleaning performance will produce.As shown in figure 5, being the lower filter of backwash rate
Core filtration stage and backwash stage schematic diagram and flushing speed effect figure.
Specific case used herein elaborates utility model design, and the explanation of above example is
It is used to help understand the core concept of the utility model.It should be pointed out that for those skilled in the art,
Under the premise of not departing from utility model design, any obvious modification, equivalent replacement or the other improvements made should all
