Abstract
The utility model relates to a centrifugal net filter, which comprises a centrifugal water-sand separator and a net filter, wherein, a partition board is arranged between the centrifugal water-sand separator and the net filter; the net filter is positioned at the upper part of the partition board; a filter screen is arranged inside the net filter; a water outlet is of one side of the net filter; the water outlet is connected with the bottom end of the filter screen through a water outlet bent head; the centrifugal water-sand separator is positioned at the lower part of the partition board; a water inlet is formed on one side of the centrifugal water-sand separator; a center water outlet pipe is arranged inside the centrifugal water-sand separator; the upper part of the center water outlet pipe is communicated with the net filter through the partition board; a conical body, which is arranged at the lower part of the center water outlet pipe, is connected with the inner wall of the centrifugal water-sand separator; a sand accumulating bin is arranged at the bottom part of the centrifugal water-sand separator; and a sewage outlet is formed on one side of the sand accumulating bin. The centrifugal net filter provided by the utility model has the beneficial effects of simple manufacture, high filtering precision, pressure resistance, abrasion resistance, long service life; and the internal water inlet structure is that the water enters from the external and goes out from the internal.
Description
Technical field
The utility model relates to a kind of water treatment facilities, relates in particular to a kind of centrifugal well strainer.
Background technology
China patent ZL.200720005221.3 discloses a kind of centrifugal, integrated water sand separator of net formula, though this filter has been simplified the structure and the operating process of equipment, make that separate centrifugal water sand separator and well strainer are integrated, also make the mobile of equipment become convenient, but this filter interior water inlet structure advances to go out in being, and the weak point of this design is: screen pack inconvenience cleaning, intensity difference, outward appearance complexity, manufacture difficulty is big.
The utility model content
The purpose of this utility model provides a kind of centrifugal well strainer, to overcome existing centrifugal, the integrated filter screen pack inconvenience of net formula cleaning, intensity difference, outward appearance complexity, the deficiency that manufacture difficulty is big.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of centrifugal well strainer, comprise centrifugal water sand separator and well strainer, be provided with dividing plate in the middle of described centrifugal water sand separator and the well strainer, well strainer is positioned at the top of dividing plate, the inside of described well strainer is provided with screen pack, one side of well strainer is provided with delivery port, and delivery port is connected with the screen pack bottom by water exit elbow; Described centrifugal water sand separator is positioned at the bottom of dividing plate, one side of centrifugal water sand separator is provided with water inlet, inside is provided with the center outlet pipe, the top of described center outlet pipe is communicated with well strainer by dividing plate, the bottom of center outlet pipe is provided with bullet and is connected with centrifugal water sand separator inwall, the bottom of described centrifugal water sand separator is provided with long-pending sand storehouse, and a side in long-pending sand storehouse is provided with sewage draining exit.
The beneficial effect of a kind of centrifugal well strainer described in the utility model is: the inner inlet structure goes out in advancing outward, makes simply filtering accuracy height, withstand voltage corrosion-resistant, long service life.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the described a kind of centrifugal network formula structure of filter schematic diagram of the utility model embodiment.
Among the figure:
1, water inlet; 2, screen pack; 3, inspection socket; 4, delivery port; 5, water exit elbow; 6, center outlet pipe; 7, bullet; 8, sewage draining exit; 9, long-pending sand storehouse; 10, Pressure gauge; 11, dividing plate; 12, well strainer; 13, centrifugal water sand separator.
The specific embodiment
As shown in Figure 1, a kind of centrifugal well strainer, comprise centrifugal water sand separator 13 and well strainer 12, be provided with dividing plate 11 in the middle of described centrifugal water sand separator 13 and the well strainer 12, well strainer 12 is positioned at the top of dividing plate 11, the inside of described well strainer 12 is provided with screen pack 2, and a side of well strainer 12 is provided with delivery port 4, and delivery port 4 is connected with screen pack 2 bottoms by water exit elbow 5; Described centrifugal water sand separator 13 is positioned at the bottom of dividing plate 11, one side of centrifugal water sand separator 13 is provided with water inlet 1, inside is provided with center outlet pipe 6, the top of center outlet pipe 6 is communicated with well strainer 12 by dividing plate 11, the bottom of center outlet pipe 6 is provided with bullet 7 and is connected with centrifugal water sand separator 13 inwalls, the bottom of described centrifugal water sand separator 13 is provided with long-pending sand storehouse 9, and a side in long-pending sand storehouse 9 is provided with sewage draining exit 8.
During use, the water that contains solid particles such as the grains of sand tangentially enters centrifugal water sand separator 13 from water inlet 1, produce eddy flow, particle in the water is under the action of centrifugal force that eddy flow produces, sandstone amasss in the sand storehouse 9 owing to the gravity effect is lowered into, water enters well strainer 12 from center outlet pipe 6, filtration by screen pack, water flows out from delivery port 4, described water inlet 1 and delivery port 4 are provided with Pressure gauge 10, by reading Pressure gauge pressure height, can judge inner obstruction and ruuning situation according to pressure differential, so that clean blowdown in time.
