Abstract
The utility model discloses a self-cleaning filter which comprises a filter casing. A water inlet pipe and a water outlet pipe are arranged on the filter casing. A tubular filter screen is arranged in the filter casing and comprises an inner layer filter screen and an outer layer filter screen. Steel balls are filled in a closed space between the inner layer filter screen and the outer layer filter screen. An annular cavity formed by the tubular filter screen and the filter casing is communicated with the water outlet pipe in sealing mode, an inner cavity of the tubular filter screen is communicated with the water inlet pipe in sealing mode, a rotating shaft is arranged in the filtering casing, and the rotating shaft penetrates the inner cavity of the tubular filter screen to be coaxially arranged with the tubular filter screen. A fur brush is arranged on the rotating shaft which is in transmission connection with a motor arranged at the top of the filter casing. When a certain amount of impurities exist, the inner layer filter screen, the outer layer filter screen and the filter portion are washed. Due to the fact that the filtering portion is stainless steel balls, the impurities attached to the surface of the steel balls can be easily removed.
Description
Technical field
The utility model relates to a kind of filter, specifically, relates to a kind of self-cleaning filter, belongs to environmental technology field.
Background technology
Filter is indispensable a kind of device on the pumped (conveying) medium pipeline, is installed in the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment usually, is used for eliminating the impurity in the medium, with the normal use of protection valve and equipment.After the fluid entering was equipped with the filter cylinder of certain specification filter screen, its impurity was stopped that the filtrating of cleaning is then discharged by filter outlet; When needs clean,, reload after the processing and get final product as long as dismountable filter cylinder is taken out; Need manually-operated, waste a large amount of manpower and materials.
The pending water of filter gets into body by water inlet, and the impurity in the water is deposited on the stainless steel filtering net, produces pressure reduction thus.Change through pressure difference switch monitoring intake-outlet pressure reduction, when pressure reduction reached setting value, electric controller was given hydraulic control valve, drive motors signal; Cause following action: the rotation of motor drives brush, filter core is cleaned, control valve is opened and is carried out blowdown simultaneously; When cleaning end, closed control valve, motor stops operating; System returns to its original state, begins to get into the next operation of filtering.Traditional filter is mainly by coarse strainer, fie screen, dirt sucking tube, compositions such as stainless steel brush or stainless steel suction nozzle, sealing ring, corrosion-inhibiting coating, turning cylinder, and the structure more complicated, cleaning effect is undesirable.
The utility model content
The problem that the utility model will solve is the some shortcomings that exist to filter, and a kind of self-cleaning filter is provided, and relatively simple for structure, cleaning effect is good, can effectively use manpower and material resources sparingly.
For addressing the above problem, the utility model adopts following technical scheme: a kind of self-cleaning filter, comprise filter housings, and it is characterized in that: said filter housings is provided with water inlet pipe and outlet pipe, is provided with the tubular filter screen in the filter housings;
The tubular filter screen comprises inner filter screen and outer filter, is filled with steel ball in the confined space between inner filter screen and the outer filter;
The annular chamber that tubular filter screen, filter housings form is communicated with the outlet pipe sealing, and the inner cavity chamber of tubular filter screen is communicated with the water inlet pipe sealing.
Further improvement as technique scheme:
Be provided with turning cylinder in the said filter housings, turning cylinder pass the tubular filter screen inner cavity chamber and with the coaxial setting of tubular filter screen;
Turning cylinder is provided with hairbrush;
The top of filter housings is provided with motor;
Motor and turning cylinder are in transmission connection.
Said filter housings comprises upper shell and lower house, and upper shell and lower house removably connect.
Be provided with flange between said upper shell and the lower house.
Be communicated with Pneumatic butterfly valve on said outlet pipe, the water inlet pipe respectively.
The end of said outlet pipe, water inlet pipe is respectively equipped with flange.
The utility model adopts above technical scheme; Compared with prior art, have the following advantages: water gets into filter by water inlet, through getting into the filtrate part of being made up of stainless shot behind the inner filter screen removal bulky grain foreign material; Then accomplish and filter through outer filter; Clear water is discharged by delivery port, and in filter process, inner filter screen, the peripheral impurity of outer filter can be piled up gradually; When impurity has when a certain amount of, filter will begin automatic cleaning process: Pneumatic butterfly valve is opened, and intakes through outlet pipe; Inner filter screen, outer filter and filtrate are partly washed, because filtrate partly is a stainless shot, so can with comparalive ease the impurity of its surface attachment be removed; After cleaning finished, Pneumatic butterfly valve was closed, and carried out the work of following one-period again; Relatively simple for structure, cleaning effect is good, is provided with two filters; Can filter cleaning, high efficiency incessantly.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Accompanying drawing 1 is the structural representation of self-cleaning filter among the utility model embodiment;
Accompanying drawing 2 is the vertical view of accompanying drawing 1;
Accompanying drawing 3 is the structural representation of the utility model embodiment middle filtrator;
Among the figure,
The 1-upper shell, 2-lower house, 3-flange, 4-outlet pipe, 5, the 51-flange, 6-tubular filter screen, 7, the 71-Pneumatic butterfly valve, 8-water inlet pipe, 9-fixing hole, 10-steel ball, 11-motor, 12-turning cylinder, 13-hairbrush, 14-inner filter screen, 15-outer filter.
The specific embodiment
Embodiment is like Fig. 1, Fig. 2, shown in Figure 3, a kind of self-cleaning filter; Comprise filter housings, filter housings comprises upper shell 1 and lower house 2 two parts, adopts flange 3 to removably connect between upper shell 1 and the lower house 2; Flange 3 is provided with fixing hole 9, and a side of filter housings is provided with outlet pipe 4, and the bottom of filter housings is provided with water inlet pipe 8; Be provided with tubular filter screen 6 in the filter housings, tubular filter screen 6 is a double-decker, comprises inner filter screen 14 and outer filter 15; Fill up tiny steel ball 10 in the confined space between inner filter screen 14 and the outer filter 15, steel ball 10 is supported by inner filter screen 14 and outer filter 15, and the annular chamber that tubular filter screen 6, filter housings form is communicated with outlet pipe 4 sealings; 8 sealings of the inner cavity chamber of tubular filter screen 6 and water inlet pipe are communicated with, and are provided with turning cylinder 12 in the filter housings, turning cylinder 12 pass tubular filter screen 6 inner cavity chamber and with the 6 coaxial settings of tubular filter screen; Turning cylinder 12 is provided with hairbrush 13, and the top of filter housings is provided with motor 11, and motor 11 is in transmission connection with turning cylinder 12; Be communicated with Pneumatic butterfly valve 71 on the water inlet pipe 8; The end of water inlet pipe 8 is provided with flange 51, is communicated with Pneumatic butterfly valve 7 on the outlet pipe 4, and the end of outlet pipe 4 is provided with flange 5.
