Under the conventional state, sewage enters the inner cavity from the first inlet, is filtered by the filter element, flows to the outer cavity, and flows out from the cylinder outlet; when the impurity adsorbed by the filter element is excessive, the pressure in the cylinder body is larger than the set value, the first inlet is disconnected, the second inlet is connected, the outlet is disconnected, and sewage enters the cylinder body from the second inlet and flows into the inner cavity from the outer cavity. Because impurity adsorbs on the filter core and flows to the outer chamber from the inner chamber, and sewage flows to the inner chamber from the outer chamber after getting into from the second entry, the flow direction is opposite, consequently can wash out impurity from the filter core for impurity breaks away from the filter core, and flows from the blow off pipe, thereby realizes the automatic clearance of filter core. Therefore, the operation is simple, the shutdown operation is not needed, and the production efficiency is improved.
The position setting of first entry and second entry, the direct effect impurity breaks away from the efficiency of filter core, based on this, further improvement lies in: the first inlet is positioned at the top of the inner cavity; the second inlet is located at the bottom of the outer chamber. Thus, when the first inlet is communicated, sewage flows from top to bottom, and when the second inlet is communicated, sewage flows from bottom to top, and the flushing direction of the sewage is opposite to the flowing direction of impurities adsorbed on the filter element, so that the impurities are convenient to separate from the filter element.

Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
Embodiment one:
as shown in fig. 1, the present utility model is a self-cleaning filter device, comprising a cylinder 1 having a filter element installed therein, thereby dividing the inside of the cylinder 1 into an outer chamber 2 and an inner chamber 3. The filter element is internally provided with an inner cavity 3 and externally provided with an outer cavity 2.
The filter element comprises a first filter element 21 and a second filter element 22, wherein the first filter element 21 is positioned inside the second filter element 22, and the filtering precision of the first filter element is lower than that of the second filter element 22. The sewage is firstly subjected to rough filtration through the first filter element 21 and then subjected to fine filtration through the second filter element 22, so that the filtering effect is improved.
The cylinder 1 is provided with a first inlet 4, a second inlet 5 and an outlet. The main water inlet pipeline 6 leads out a first water inlet pipe 7 and a second water inlet pipe 8 which are parallel; the first water inlet pipe 7 is connected with the first inlet 4 and is provided with a first electric valve 9; a second inlet pipe 8 is connected to the second inlet 5 and is fitted with a second electrically operated valve 10. The first electric valve 9 and the second electric valve 10 are opened and closed in opposite states, so that the first inlet 4 and the second inlet 5 are opened and closed in opposite states. The second water inlet pipe 8 is also provided with a one-way valve 11 for preventing sewage from flowing back into the second water inlet pipe 8. The outlet is connected with a water outlet pipe 18, and the water outlet pipe 18 is provided with an electric stop valve 19.
A drain pipe 17 is arranged at the bottom of the filter element, and a third electric valve 20 is arranged on the drain pipe 17. The cylinder 1 is also provided with a pressure sensor for detecting the pressure in the cylinder 1 so as to control the on-off of the electric valve and the stop valve 19.
The electric valve is an electric ball valve.
In a normal state, sewage enters the inner cavity 3 from the first inlet 4, the second electric valve 10 and the third electric valve 20 are closed, and the stop valve 19 is opened. Filtered by the filter element, flows into the outer cavity 2 and flows out from the outlet of the cylinder body 1. When the impurities adsorbed by the filter element are excessive, the pressure in the cylinder 1 is larger than a set value, the first inlet 4 is disconnected, the second inlet 5 is connected, the outlet is disconnected, and sewage enters the cylinder 1 from the second inlet 5 and flows into the inner cavity 3 from the outer cavity 2. Because the impurity adsorbs on the filter core and flows from inner chamber 3 to outer chamber 2, and sewage flows from outer chamber 2 to inner chamber 3 after getting into from second entry 5, the flow direction is opposite, consequently can wash out impurity from the filter core for impurity breaks away from the filter core, and flows out from blow off pipe 17, thereby realizes the automatic clearance of filter core. Therefore, the operation is simple, the shutdown operation is not needed, and the production efficiency is improved.
Embodiment two:
the difference from the first embodiment is that: the first inlet 4 is located at the top of the cavity 3; the second inlet 5 is located at the bottom of the outer chamber 2. Thus, when the first inlet 4 is communicated, sewage flows from top to bottom, and when the second inlet 5 is communicated, sewage flows from bottom to top, and the flushing direction of the sewage is opposite to the flowing direction of impurities adsorbed on the filter element, so that the impurities are convenient to separate from the filter element.
Embodiment III:
compared with the embodiment, the difference is that: as shown in fig. 3, the first filter element 21 is wrapped with a rigid first perforated pipe 12; the second filter element 22 is wrapped with a second rigid perforated pipe 13. The pore tube limits the outside of the filter element, improves the structural strength of the filter element, and avoids expansion damage when the pressure is too high. The hole pipe is formed by coiling the hole plate.
Embodiment four:
compared with the three phases of the embodiment, the difference is that: as shown in fig. 2, the upper end of the first perforated pipe 12 is provided with a first flange 14; the upper end of the second hole pipe 13 is provided with a second flange 15; the first flange 14 is fixedly connected with the second flange 15 through bolts; the second flange 15 is fixedly connected with a mounting plate 16 on the cylinder 1 through bolts. The installation structure strength of the filter element is improved due to the arrangement of the flange, and the position deviation of the filter element is avoided when the pressure is too high.
