Abstract
The utility model discloses a manual backwash filter comprising a barrel, wherein the barrel is provided with a water inlet at the lower end and a water outlet at the upper end; the barrel is internally provided with an upper filter screen and a lower filter screen which are vertically and radially arranged at intervals; a filter cavity is defined by the two filter screens and the inner wall of the barrel; a partitioning device capable of partitioning the inner cavity of the barrel into an upper cavity and a lower cavity is fixedly arranged below the lower filter screen in the barrel; and a pollution discharge device communicated with the filter cavity is fixedly connected above the partitioning device and on the outer wall of the barrel. When the manual backwash filter is used for flushing impurities on the filter screens, impurities can be discharged out of the barrel by means of the pressure of filtered water; and the manual backwash filter has the characteristics of simple structure and low cost. The manual backwash filter is suitable for being used as a filter mounted on a water supply pipe requiring for filtering impurities in water.
Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of manual backwashing filter device.
Background technology
Along with scarcity and the pollution of water resource are day by day serious, people more and more pay attention to processing and the recycling of waste water.The surface water such as water for industrial use, boiler feed water, air-conditioning cooling circulating water, river river all need to carry out filtration treatment.Filter is the equipment of removing the impurity such as suspension in water.In filter process, medium from the filter inner chamber after filtration net filtration flow to outer side outlet, and impurity can be deposited on filter screen inside or be embedded in opening of sieve.Along with the long-term use of filter, the filter net jam situation can be more and more serious, causes that strainability descends, and even causes secondary pollution.
Have filter now in water treatment procedure, the regular backwash of filter screen need, the pressure that the backwash flow is large and need are certain.And the structure of filter becomes increasingly complex at present, also from strength to strength, cost is also more and more higher thereupon for function, when among water, impurity content is less, uses full-automatic back washing filter can form on the contrary waste, and increases cost.
The utility model content
For solving the above deficiency existed in prior art, the utility model provides a kind of manual backwashing filter device, and when flushing filtering net impurity, it can utilize self pressure of filtered water that impurity is discharged to cylindrical shell, has characteristics simple in structure, with low cost.
For achieving the above object, the technical scheme that adopts of the utility model is as follows:
A kind of manual backwashing filter device, comprise cylindrical shell, the lower end of described cylindrical shell is provided with water inlet, upper end is provided with delivery port, in cylindrical shell, be provided with the upper filter screen, the lower filter screen that radially arrange of being separated by up and down, between the inwall of two filter screens and cylindrical shell, surround filter chamber, in the lower filter screen below, be fixed with and cylinder lumen can be cut off and is the partition apparatus in upper and lower two chambeies in described cylindrical shell; Top in partition apparatus on cylinder body outer wall also is fixedly connected with the blowdown apparatus be communicated with filter chamber.
As to restriction of the present utility model, described partition apparatus comprises the dividing plate of being located in cylindrical shell, the internal diameter of the diameter of described dividing plate and At The Height cylindrical shell of living in is suitable, the inwall of dividing plate and cylindrical shell is along diametric jointed shaft, to be hinged, and the pin joint place is fixedly connected with after level runs through barrel wall stretches out the outer swing handle of cylindrical shell.
As to another kind of restriction the of the present utility model, described blowdown apparatus comprise be located at the blow-off pipe that is communicated with filter chamber on barrel wall, to be located at cylindrical shell outer and connect firmly the valve for the perforation of control of sewage disposal pipe or shutoff with blow-off pipe.
Owing to having adopted technique scheme, compared with prior art, obtained technological progress is the utility model:
When filter of the present utility model need to clean filter screen, the rotation swing handle makes dividing plate that cylinder lumen is cut off, be that water inlet is by shutoff, then open the blow-off pipe valve, because the water after filtering has pressure, water can flow backwards downwards from the delivery port direction, flushing filtering net, and the impurity on filter screen can be from the blow-off pipe discharge filter be communicated with the filter screen inner chamber.
In sum, the utlity model has characteristics simple in structure, with low cost.
The utility model is suitable as filter, is installed on the supply channel that needs impurity in filtered water.
The accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is done further to describe in detail.
Fig. 1 is the overall structure schematic diagram of the utility model embodiment;
Fig. 2 is the cutaway view of Fig. 1.
In figure: 1, delivery port; 2, cylindrical shell; 3, dividing plate; 4, swing handle; 5, water inlet; 6, blow-off pipe; 7, valve; 81, upper filter screen; 82, lower filter screen.
The specific embodiment
Embodiment
A kind of manual backwashing filter device, structure as shown in Figure 1-2, comprise cylindrical shell 2.
The lower end of cylindrical shell 2 is provided with water inlet 5, and upper end is provided with delivery port 1, and inside is provided with between the upper filter screen 81, lower filter screen 82, two filter screens and cylindrical shell 2 inwalls that radially arrange of being separated by up and down and surrounds filter chamber.
On cylindrical shell 2, be fixed with blowdown apparatus in lower filter screen 82 belows, it comprises the dividing plate 3 of being located in cylindrical shell 2, the internal diameter of the diameter of dividing plate 3 and At The Height cylindrical shell 2 of living in is suitable, the right-hand member of dividing plate 3 is with the boss protruded to the right, the inwall place coordinated with dividing plate 3 boss ends of cylindrical shell 2 is provided with recessed grain, boss is inserted in groove, and can in groove, rotate.The other end be positioned on same diameter with boss of dividing plate 3 is that the left end level stretches out and passes cylindrical shell 2, boss and groove coordinates in addition, realized that the inwall of dividing plate 3 and cylindrical shell 2 is to be hinged along diametric(al), the hinge point place is provided with sealing gasket, and left end pin joint place is fixedly connected with level and is located at the outer swing handle 4 of cylindrical shell 2.
Top in partition apparatus on cylindrical shell 2 walls also is fixedly connected with the blowdown apparatus be communicated with filter chamber, it comprises blow-off pipe 6, valve 7, blow-off pipe 6 is located on cylindrical shell 2 walls and is communicated with filter chamber, and valve 7 is fixed on blow-off pipe 6 and is positioned on the outer position of cylindrical shell 2, connects or shutoff for control of sewage disposal pipe 6.
When the present embodiment was used, water entered cylindrical shell 2 inner chambers from water inlet 5, from delivery port 1, was flowed out after two strainer filterings.Dividing plate 3 is put or tilting for perpendicular.When after the long-time use of this manual backwashing filter device, needing to clean two filter screens, rotation swing handle 4 is the level of state dividing plate 3, cylindrical shell 2 inner chambers are cut off, be water inlet 5 by shutoff, open simultaneously valve 7, blow-off pipe 6 is connected, because the water after filtering has pressure, water can flow backwards downwards from delivery port 1, rinses two filter screens, and the impurity on two filter screens can be from discharge filter the blow-off pipe 6 be communicated with filter chamber.
