Description
Technical field
The utility model relates to protection field, is specially a kind of excess flow protection device of filter.
Background technology
Adopting quartz sand filtration is to remove in water one of effective means of suspension, is advanced treatment of wastewater, reusing sewage and to important unit in water treatment.Its effect is that the pollutant having flocculated in water is further removed, and it reaches the object of water purification by the holding back of filtrate, sedimentation and suction-operated.Therefore, quartz filter is comparatively common filter, quartz filter is pressure type filtering purifying equipment, can utilize quartz sand to remove the suspension in water, silt sand filter blanket is held back, former water is purified, and the water after filtration generally meets the requirement of water for industrial use, domestic water and the municipal water supply of drinking water quality standard.
But; easily there will be in use the water to be filtered in tank body (1) more, and pressure is when very large, existing quartz filter does not have corresponding protective device; as there is for a long time this situation, the service life of quartz filter will be shortened greatly.
Utility model content
The application's object is to provide a kind of excess flow protection device of filter, to solve quartz filter in the time that internal pressure is larger, there is no the problem of corresponding protective device.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of excess flow protection device of filter is arranged on quartz filter, quartz filter comprises tank body (1) and front filter (11), it is characterized in that: the water inlet end of described front filter (11) is provided with water intaking valve (13), the bottom of front filter (11) is connected with tank body (1) by seam (12), in described tank body (1), be provided with upper and lower two pipelines, upper pipeline is provided with enterprising valve (6) and upper valve (7), under being provided with, enter valve (8) and lower valve (9) on lower pipeline, two pipelines come together in discharge outlet (3) again, the top of described tank body (1) is provided with overflow pipe (14), be provided with overflow plate (15) on the top of overflow pipe (14).
Further, described overflow pipe (14) side is provided with tank body Pressure gauge (16), and described tank body Pressure gauge (16) is directly installed on tank body (1).
Further, in described front filter (11), be provided with four metafiltration cores, two kinds of different filter cores alternately filter.
Further, the top of described tank body (1) is provided with air bleeding valve (5).
Further, described lower pipeline is provided with Pressure gauge (4).
Further, being made by carbon steel or fiberglass of described tank body (1).
Further, described tank body (1) bottom is provided with discharge gate (10), and the middle and lower part of described tank body (1) is provided with outlet valve (2).
The beneficial effects of the utility model are:
The utility model is arranged on the top of quartz filter; and have Pressure gauge to show tank internal pressure situation, in the time of pressure overrun, unnecessary water will flow out from protective device; thereby alleviate the internal pressure of tank body, extend the service life of quartz filter.
Brief description of the drawings
Fig. 1 is the structural representation of quartz filter.
Tank body 1; Outlet valve 2; Discharge outlet 3; Pressure gauge 4; Air bleeding valve 5; Enterprising valve 6; Upper valve 7; Under enter valve 8; Lower valve 9; Discharge gate 10; Front filter 11; Seam 12; Water intaking valve 13; Overflow pipe 14; Overflow plate 15; Tank body Pressure gauge 16.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The excess flow protection device of filter is arranged on quartz filter top, the structure of quartz filter as shown in Figure 1, mainly comprise tank body (1) and front filter (11), wherein be provided with water intaking valve (13) at the water inlet end of front filter (11), the bottom of front filter (11) is connected with tank body (1) by seam (12), front filter (11) filters the water entering in tank body (1) in advance, because front filter (11) is easy to replace and install, thereby alleviate the operating pressure in tank body (1), and then the excess flow protection device filter element replacing frequency of minimizing filter, in front filter (11), be provided with four metafiltration cores, two kinds of different filter cores alternately filter.
Multiple pipelines and valve distribute in the inside of tank body (1), in tank body (1), be provided with upper and lower two pipelines, upper pipeline is provided with enterprising valve (6) and upper valve (7), under being provided with, enter valve (8) and lower valve (9) on lower pipeline, two pipelines come together in discharge outlet (3) again, be provided with outlet valve (2) in the middle and lower part of tank body (1), for the water after exhaust filtering.In order to observe at any time the pressure condition in tank body (1), on lower pipeline, be provided with Pressure gauge (4).Because the excess flow protection device of filter is brought gas into water in the time working; for the gas in tank body (1) is discharged; do not affect the normal work of the excess flow protection device of filter; be provided with air bleeding valve (5) at the top of tank body (1); be provided with discharge gate (10) in the bottom of tank body (1), for discharge.
