Abstract
The utility model relates to an automatic self-cleaning filter, which comprises a tank body, wherein a transverse partition plate is arranged between the water inlet and the water outlet of an inner cavity of the tank body, and divides the inner cavity of the tank body into a turbid liquid cavity and a clean liquid cavity; and filter columns are uniformly distributed on the transverse partition plate. The automatic self-cleaning filter is characterized in that: a backwash mechanism is arranged in the tank body, and consists of a speed reducer, an output shaft, a sewage drainage pipe and a differential pressure controller; the speed reducer is connected with the output shaft, passes through the clean liquid cavity, and reaches the turbid liquid cavity; the sewage drainage pipe is connected to the output shaft through a key; pressure meters connected with the turbid liquid cavity and the clean liquid cavity respectively are fixedly connected to the surface of the tank body, and are connected with the differential pressure controller; and the speed reducer is connected with the differential pressure controller. The automatic self-cleaning filter has the beneficial effects that: according to a backwash technology, the manual cleaning times are reduced; when impurities are accumulated to a certain thickness in the filter columns, a pressure difference is generated between the turbid liquid cavity and the clean liquid cavity; and therefore, the differential pressure controller can automatically control the backwash mechanism to start or the backwash mechanism can be manually started so as to remove the filtered impurities.
Description
Technical field
The utility model belongs to filter, relates 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.
The utility model content
The utility model 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 utility model is realized 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 the utility model structural representation.
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; Details are as follows to the specific embodiment that provides according to the utility model: 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 the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
