Description
Technical field:
The present invention relates to the filter plant in a kind of chemical engineering industry field, particularly a kind of filtration contains the self-cleaning strainer of granular material.
Background technology:
At the chemical engineering industry production field, often need to will come into operation again or packing and selling behind the material filtering; In the process of filtering, the particulate contamination that filter screen often can be sneaked in the material is stopped up, and affects filter efficiency; Usually could again come into operation after need disassembling filter, the screen pack of taking-up inefficacy, the screen pack of reinstalling cleaning and assembling filter device.Will there be many problems like this, can reveal when disassembling filter such as the former material that remains in the filter cavity, cause environmental pollution; The material waste is larger; The filter screen consumption rate is larger, and other Clean-consumptive material use amounts also can rise; Dismounting filter and replacing filter screen need than multi-step, lose time, and reduce production efficiency; Operating personnel's work load is larger; Produce easily security incident etc. in the dismounting filter procedure.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of self-cleaning strainer, the technical scheme that it adopts is: a kind of self-cleaning strainer, comprise the protecgulum that is provided with charging aperture, the bonnet that is provided with discharging opening, place screen pack between protecgulum and the bonnet, the fixedly bracing frame of screen pack and the orifice plate that supports screen pack and allow material to pass through, wherein said protecgulum and bonnet removably connect, and characterized by further comprising a cover self-cleaning system.
The present invention further technical characterictic is:
Described self-cleaning system comprises: the unidirectional striker plate that described protecgulum is inner hinged, the waste sludge discharge valve that described protecgulum bottom arranges, the recoil material inlet control valve that described bonnet top arranges, the clean materials drain valve that described bonnet bottom arranges, the clean materials package valve that arranges on the described discharging opening.
Described protecgulum is connected by set bolt with bonnet.
Also be provided with sealing ring between described protecgulum and the bonnet.
Be provided with backflush unit between described orifice plate and the bonnet.
Described backflush unit comprises recoil material collector plate, drive the drives impeller that recoil material collector plate is rotated, and the power source control valve of drives impeller, material collector plate and the drives impeller of wherein recoiling is installed in rotation on the axle that is fixed in the orifice plate center, and the power source control valve of drives impeller is arranged on bonnet top.
Be provided with axle sleeve between described recoil material collector plate and drives impeller and the axle, axle is provided with the stop nut of restriction axle sleeve zone of action near an end of drives impeller.
When the normal filtration material, the unidirectional striker plate that is positioned at the filter protecgulum is freely opened under the thrust of material pressure reduction, make material normally by and pass screen pack bracing frame, screen pack, orifice plate, and pass recoil material collector plate, final by the clean materials package valve, finish filter process;
After screen pack was stopped up by impurity gradually, filter efficiency can reduce greatly; Stop filter operation, close the clean materials package valve, open the clean materials drain valve, be stranded in clean materials in the filter with what container received that the clean materials drain valve discharges, avoid waste;
Behind the clean materials that in receiving filter, is detained, close the clean materials drain valve, open recoil material inlet control valve, under the thrust of recoil material, be positioned at unidirectional striker plate and the filter protecgulum inwall gluing, sealing of filter protecgulum, open simultaneously the waste sludge discharge valve, and storing containers is collected filter residue below the waste sludge discharge valve; Preventing that filter residue from sneaking into causes secondary pollution in the raw material; The source control valve can also turn on the power, drives impeller is made circular motion around the axle that is fixed in the orifice plate center, it drives simultaneously recoil material collector plate by axle sleeve and makes circular motion around the axle that is fixed in the orifice plate center, so that the stepless action of recoil material is in each sector of screen pack, to rinse the impurity that adheres on the screen pack well; Simultaneously filter screen since the effect of bracing frame still can secure lock in the middle of orifice plate and bracing frame.
The invention has the beneficial effects as follows: because described filter comprises a cover self-cleaning system, therefore avoid disassembling filter, the clean materials that is stranded in the filter can effectively be reclaimed, and there is not the problem of filter residue secondary pollution raw material simultaneously in filter residue by centralized collection; But the filter screen Reusability also reduces the use of disassembling Clean-consumptive material in the filter procedure simultaneously; Save the dismounting filter and change the needed time of filter screen; Operating personnel's work load is less, only needs to get final product by the step operated valve; Avoid in the dismounting filter procedure, weight falls caused security incident.
