Abstract
The utility model provides a full-automatic water filter which relates to the technical field of a water filter. The utility model is mainly characterized in that a filter screen cylinder is connected to a cylinder body (7), a water flow turning valve is connected to the filter screen cylinder and is connected to the cylinder body through the axial movable fit of a motor operator, and an electric valve is connected to a sewage discharging port through a butterfly valve. The full-automatic water filter is suitable for using as a matching product for the items of light industries, hydroelectric industries, fire and electric industries and petrochemical industries thereof and has the advantages of small size, light weight, convenient maintenance, free hand-operation and automation conversion and forward and back flushing effect on filtration, sewage removal and sewage discharge.
Description
Affiliated technical field
The utility model relates to a kind of full-automatic water filter, belongs to the water filter technical field, is applicable to that water power, thermoelectricity, Ferrous Metallurgy, light industry and petrochemical industry project thereof are as auxiliary products.
Background technology
Domestic existing water filter generally has fixed water filter at present, and the mode that is the dismounting filter screen is carried out drainage.Another kind is the rotary type water filter, is by the people and moves axle, rotates filter screen by axle and realizes removing contamination.Their weak point is that floor space is big, and space availability ratio is low, needs the basis to install, concreting, work long hours and could overhaul inside after must tearing body open, exist and can not carry out " backwash ", and the problem that can not remove effectively of some silt still.
Summary of the invention
In order to overcome the deficiency of existing water filter, the utility model provides a kind of full-automatic water filter, this water filter has that volume is little, in light weight, maintenance is convenient, manually and automatically can freely change, and can carry out " positive and negative flushing ", has automatic fitration, removes contamination, the function of blowdown.
The technical scheme that its technical problem that solves the utility model adopts (Fig. 1) is: flange (1), flanged (FLGD) outlet pipe (5), blow-off pipe (11), the sleeve pipe of YE (4), differential pressure controller (9) and Pressure gauge (6) are connected on the cylindrical shell (7), in cylindrical shell (7), be connected with filtering net cylinder (2), flow direction-changing valve (3) is connected in the filtering net cylinder (2), and axially being connected movingly on the cylindrical shell (7) by YE (4), motor-driven valve (10) is connected on the sewage draining exit (11) by the dish valve, the control cable (8) of control cabinet (12) connects YE (4) respectively, motor-driven valve (10) and differential pressure controller (9), Pressure gauge (6) connects differential pressure controller (9), is connected with manual handle on YE (4) and the blowdown motor-driven valve (10) and constitutes.The course of work of the present utility model is the water that filters when needing, connect by pipeline on the flange (1,5) of entery and delivery port, water just enters from the filtering net cylinder of electric filter device (2), the small part dirt just accumulates on the filter screen, impurity is deposited in the sewage draining exit bottom by collecting mouth in the water, this filtration blowdown process is called regularly " just washing ".The pressure differential that forms inside and outside dirt accumulates in screen tube reaches preset value (55～414KPa) time, differential pressure controller reaches control cabinet (12) with signal, providing instruction motor-driven valve (10) action by cyclelog (12) opens sewage draining exit and carries out blowdown, YE (4) is instigated flow direction-changing valve (3) half-twist simultaneously, change the current approach, carry out current " backwash " filter screen, the backwash filter screen time is provided with time-program(me) control (1～100 minute) by control cabinet, after time to be cleaned finishes, blowdown dish valve cuts out, and blowdown finishes.This cleans the blowdown process is " backwash ".
The beneficial effects of the utility model are: after 1, the water dirt that is entered by water inlet passes through filter screen, on screen surface, impurity rushes at the impurity collection section by current, discharge to the sewage draining exit bottom, when inside and outside differential pressure reaches certain value on the screen tube, flow direction-changing valve half-twist, blowoff valve is opened, and the water ecto-entad carries out " backwash " and is discharged by sewage draining exit.Because the special construction of this water filter has dirt is filtered, " just washing " process that impurity is collected.2, because water inlet directly is connected with flange with delivery port, do not need to reserve the basis, carry out concreting.And the volume of this product is 1/4 of existing water filter, can be arranged in a side of factory building or wall, actually takes up room for a short time, has the pipeline of being convenient to mounting arrangements, is that a kind of volume is little, lightweight product.3, the utility model is full-automatic water filter, only needs a people to open blind flange, and filter screen is taken out, and can carry out large repairs to complete machine, hardly with maintenance, has the characteristics easily of overhauling at ordinary times.4, on YE and motor-driven valve, hand gear has been installed owing to adopting, has only been needed crank handle just can manually filter, clean, therefore the utlity model has manual and automatic two kinds of functions.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure chart of the present utility model.
1 is water-in flange among the figure, and 2 is filtering net cylinder, and 3 is the flow direction-changing valve, and 4 is YE, and 5 is water-output flange, and 6 is Pressure gauge, and 7 is cylindrical shell, and 8 is cable, and 9 is differential pressure controller, and 10 is motor-driven valve, and 11 is sewage draining exit, and 12 is control cabinet, and 13 are the maintenance blind flange.
The specific embodiment
In Fig. 1, be that DN150 is an example to import and export latus rectum, cylindrical shell (7) is made welding by national pressure container standard, and φ 300 * 845mm filtering net cylinder (2) is made by the filtering accuracy requirement that the user needs.Into and out of the water hole, blowdown oral pore, YE perforate carry out the perforate welding by national pressure container standard and take over.Select for use the flange tight fit of prior art to be installed on the entery and delivery port, the maintenance blind flange is threaded on the cylindrical shell (7), YE (4) and flow direction-changing valve (3) are bought in market, and the axle by YE is installed on the interior flow direction-changing valve (3) of cylindrical shell (7) and filtering net cylinder (2) movingly.Select for use existing motor-driven valve (10) by axially being mounted on the dish valve in the sewage draining exit (11), Pressure gauge (6), differential pressure controller (9) is installed on the cylindrical shell (7), adopt domestic existing PVC type PCB to make controller (12), when regularly removing contamination, PVC programmable control setting-up time is 0～1000 hour, and " backwash " time set is 1～100 minute.And connect YE (4), motor-driven valve (10) with cable (8), and differential pressure controller (9), Pressure gauge (6) connects differential pressure controller (9).Crank handle is installed in YE (4) and motor-driven valve (10) is gone up formation.
