Abstract
The invention relates to an automatic cleaning filter. Included is a tank body; a diaphragm plate is arranged between the water outlet and water inlet on the tank inner cavity; the diaphragm plate divides the tank inner cavity into a suspension cavity and a clear liquid cavity, and is equipped with filtering columns uniformly. The automatic cleaning filter has the following characteristics: the tank body is provided with a backwashing mechanism; the backwashing mechanism comprises a speed reducer, an output shaft, a blowing pipe and a differential pressure controller; the speed reducer is connected with the output shaft and passes through the clear liquid chamber to the suspension cavity; the output shaft is in keyed joint with the blowing pipe; the tank surface is fixed connected with pressure gages connecting to the suspension cavity and the clear liquid chamber respectively; the pressure gages are connected with the differential pressure controller; and the speed reducer is connected with the differential pressure controller. The invention has beneficial effects that the backwashing technology is used to reduce artificial cleaning frequencies; when impurities accumulate to a certain thickness in the filtering column, a pressure difference between the suspension cavity and the clear liquid chamber is occurred; and then the backwashing mechanism can be started by the differential pressure controller automatically or by hand to remove filter residue.
Description
Technical field
The invention belongs to filter, relate in particular to a kind of automatic self-cleaning filter that is used for seawater desalination systems such as bitter and seawater.
Background technology
The filter for installation of the long-term dependence on import of desalinization project.In use occur with many problems, as: artificial cleaning frequency is high, operation is continuously produced in influence; Filter effect is undesirable; It is little to bear intake pressure, causes problems such as screen pack distortion.Demand releasing the filter of production domesticization in the industry urgently, to address the above problem.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art; A kind of automatic self-cleaning filter that is used for seawater desalination systems such as bitter and seawater is provided, and the filter of production domesticization utilizes backwashing technology, reduces artificial wash number; Can bear the into pressure of water, avoid the screen pack distortion.
The present invention realizes a kind of automatic self-cleaning filter for realizing above-mentioned purpose through following technical scheme; Comprise between the intake-outlet of tank body, tank inner chamber and be provided with diaphragm plate; Diaphragm plate is divided into turbid sap cavity and clear liquid chamber with tank inner chamber, is evenly equipped with Filter column on the diaphragm plate, it is characterized in that: backwash mechanism is housed in the said tank body; Said backwash mechanism is made up of reductor and output shaft, blow-off pipe, differential pressure controller; Said reductor connects output shaft and passes the clear liquid chamber to turbid sap cavity, and keyed jointing blow-off pipe on the output shaft, said tank surface are connected with respectively the Pressure gauge that is connected with the clear liquid chamber with turbid sap cavity; Said Pressure gauge is connected with differential pressure controller, and reductor is connected with differential pressure controller.
Beneficial effect: utilize backwashing technology, reduce artificial wash number, when impurity runs up to certain thickness in Filter column, can make turbid sap cavity and clear liquid chamber produce pressure differential.At this moment can also can manually boot the recoil mechanism by the automatic control of differential pressure controller, filter residue is removed.Filter column can bear the into pressure of water, avoids the screen pack distortion.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, tank body, 2,3, intake-outlet, 4, diaphragm plate 5, Filter column, 6, reductor, 7, output shaft, 8, blow-off pipe, 9, differential pressure controller, 10, Pressure gauge.
The specific embodiment
Below in conjunction with preferred embodiment; To details are as follows according to the specific embodiment provided by the invention: see accompanying drawing for details; A kind of automatic self-cleaning filter, comprise tank body 1, tank inner chamber intake-outlet 2, be provided with diaphragm plate 4 between 3, diaphragm plate is divided into turbid sap cavity and clear liquid chamber with tank inner chamber; Be evenly equipped with Filter column 5 on the diaphragm plate; Backwash mechanism is housed in the said tank body, and said backwash mechanism is made up of reductor 6 and output shaft 7, blow-off pipe 8, differential pressure controller 9, reductor outside housing with the motor one.Said reductor connects output shaft and passes the clear liquid chamber to turbid sap cavity; Keyed jointing blow-off pipe on the output shaft; Said tank surface is connected with respectively the Pressure gauge 10 that is connected with the clear liquid chamber with turbid sap cavity, and said Pressure gauge is connected with differential pressure controller, and reductor is connected with differential pressure controller.
Diaphragm plate in the tank body is divided into turbid sap cavity and clear liquid chamber with its inner chamber.Turbid liquid gets into turbid sap cavity through import, gets into the inner chamber of filter element again through the dividing plate hole.Impurity greater than the filter element slit is trapped, and clear liquid passes the slit and arrives the clear liquid chamber.All converge in the clear liquid chamber with the filter element filtered liquid, see off from outlet at last.The dividing plate diameter is identical with the housing internal diameter, is welded in the internal diameter, places Filter column on the dividing plate; Water inlet is filtered through Filter column particulate matter is stayed the Filter column inwall, and when differential pressure indicator reached certain numerical value, electric rotating machine started automatically; Electric rotating machine and blow-off pipe moved in coaxial; The alignment filter post, cleaning and filtering post one by one, sewage is discharged in blow-off pipe.Backwash mechanism is in housing, is to lean on discharge pressure back flush Filter column.When impurity runs up to certain thickness in filter element, can make turbid sap cavity and clear liquid chamber produce pressure differential.At this moment can control recoil mechanism automatically by differential pressure controller and start, also can manually boot backwashing system, filter residue is removed.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
