Abstract
Description
Technical Field
[0001] The present application relates to the technical field of filter equipment, and in particular to a self-exclusion filter. Background Art
[0002] In the field of filter technology, traditional Y-shaped filters are small devices that remove small amounts of solid particles from liquids, protecting the normal operation of the equipment. When the fluid enters a filter cartridge equipped with a filter screen of a certain specification, its impurities are blocked, while the clean filtrate is discharged from the filter outlet. When cleaning is required, the detachable filter cartridge is simply removed, processed, and reinstalled, making it extremely convenient to use and maintain. However, traditional Y-shaped filters usually have an independent filter screen installed within the filter body. After using the Y-shaped filter for a period of time, the sealing end cap on one side of the Y-shaped filter needs to be opened regularly, and the filter screen needs to be removed for cleaning and maintenance to ensure that the Y-shaped filter will not clog during subsequent use. For some larger pipes and valves, cleaning by removing the filter screen is relatively inconvenient, time-consuming, and labor-intensive, resulting in low work efficiency.
[0003] In the prior art, for example, the authorization announcement is CN 217698203 U, and the application name is a dual-channel Y-type filter structure utility model. The filter includes a first filter channel and a second filter channel, both ends of which are connected to a Y-type connector, one end of which is connected to a flange, and both ends of the first filter channel and the second filter channel are respectively provided with an inlet valve and an outlet valve, and the first filter channel and the second filter channel are both installed with a filter screen. A backflush disk is installed on the side of the filter screen close to the outlet valve, and a sewage outlet is opened on the side of the first filter channel and the second filter channel close to the inlet valve. A flow sensor is installed on the side wall of the first filter channel and the second filter channel close to the outlet valve. This application sets up structures such as a backwash plate, a sewage outlet, and a micro high-pressure water pump. By backwashing, the surface of the filter screen can be automatically flushed, so that impurities fall off the surface of the filter screen and are discharged from the sewage outlet. There is no need to manually disassemble the filter screen for cleaning, which makes it more convenient to use and improves work efficiency. At the same time, through the setting of an alarm and a flow sensor, when the filter screen is blocked and the flow rate is small, an automatic alarm can be triggered to remind you so that the filter can be cleaned in time.
[0004] The existing technology requires an additional high-pressure water pump to perform backflushing through pipeline design. On the one hand, when the pressure at the water inlet end is usually greater than the pressure at the water outlet end, the high-pressure water pump is required to provide a larger pressure to achieve backflushing without closing the water inlet end valve. If the water inlet end valve is closed, an additional new water source is required for re-flushing, so flushing is inconvenient. On the other hand, the Y-shaped deformation is performed through the separated double channels, and the equipment occupies a large space horizontally. Summary of the Invention

[0035] In response to the above problems, an embodiment of the present application provides a self-exclusion filter. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.
[0036] like Figures 1 to 6 The self-exhausting filter shown in the figure comprises: a cavity 1, the filter cavity of the present application is configured as a square, a water inlet 2 is configured at one end of the cavity 1, a water outlet 3 is configured at the other end, a central partition 4 is configured in the middle of the cavity 1 to divide the cavity 1 into a first channel 12 and a second channel 13, the water inlet 2 and the water outlet 3 are connected to the first channel 12 and the second channel 13 at the same time and form two mutually connected Y-shaped channels; a sewage outlet 11 is configured at the bottom of the first channel 12 and the second channel 13, and a filter plate or filter screen 7 is provided on the channel of the sewage outlet 11; and
[0037] Guide plate 5, square baffle 6, channel partition 9, sewage baffle 10, first driver 51, second driver 61, third driver 91, fourth driver 101;
[0038] Among them, the guide plate 5 is transferred and set at the intersection of the Y-shaped channels at one end of the water outlet 3, the square baffle 6 is transferred and set at the intersection of the Y-shaped channels at one end of the water inlet 2, the first driver 51 is set outside the cavity 1 and drives the guide plate 5 to rotate to open and close the two channels, the second driver 61 is set outside the cavity 1 and drives the square baffle 6 to rotate to open and close the two channels, a channel partition 9 is transferred and set in the first channel 12 and the second channel 13 respectively, the third driver 91 is set outside the cavity 1 and drives the channel partition 9 to rotate to open and close the channels, the sewage baffle 10 is transferred and set at the sewage outlet 11, and the fourth driver 101 is set outside the cavity 1 and drives the sewage baffle 10 to rotate to open and close the sewage outlet 11.
[0039] During operation, the square baffle 6 rotates to close one of the two channels. The channel baffle 9 in the closed channel rotates to separate the channels again, and the sewage baffle 10 rotates to open the sewage outlet to prepare for sewage discharge. At the same time, the rotation of the guide plate 5 causes the clean water filtered from the other channel to flow back to the filter plate or filter screen 7 in the other channel after passing through the guide plate 5, achieving non-stop backwashing of the filter plate or filter screen 7. In this way, the two channels are circulated to achieve backwashing of both channels.
[0040] In this way, the present application divides the cavity into two channels through a central partition 4, and sets a guide plate 5 at the end of the channel, that is, the water inlet and outlet, and a square baffle 6 to open and close the channel so that the water flow can be controlled to flow through which channel. At the same time, a sewage outlet 11 is set on each channel, and a sewage baffle 10 that controls the sewage outlet 11 is combined with the channel partition 9 of the equipment inside the channel to open and close the sewage outlet 11 to achieve backwashing. Taking advantage of the characteristic that backflow will be formed after water flow and obstruction, a filter plate or 7 and a corresponding sewage outlet are set at the reflux point to facilitate the backwashing of the filter plate or filter screen 7. This device does not require additional power equipment for backwashing, nor does it require additional pipelines. It only needs to control the rotation and opening and closing of the corresponding baffle to achieve backwashing of the filter plate or filter screen 7. The flushing is convenient and the equipment occupies a small space.
[0041] In one embodiment, the first channel 12 and the second channel 13 are configured as square channels to facilitate the rotation and opening and closing of each partition.
[0042] In one embodiment, the guide plate 5 is configured as an isosceles triangle plate, and one side facing the central partition plate 4 is configured as an arc to facilitate water flow to form a backflow to flush the filter plate or filter screen 7 .
[0043] In one embodiment, the angle of the guide plate 5 facing the water outlet 3 is set at 120 degrees, and the angle faces the central partition 4 to facilitate the connection and disconnection of the two channels and to block the backflow.
[0044] In one embodiment, a locking plate 14 for locking the sewage baffle 10 and a fifth driver 141 for driving the locking plate 14 to rotate are provided at the bottom of the cavity 1 to facilitate locking the sewage outlet 11 during normal operation.
[0045] In one embodiment, on the one hand, in order to prevent the filter plate or filter screen 7 from being damaged due to excessive water pressure, the filter plate or filter screen 7 is tilted to increase the thickness of the filter plate or filter screen 7 in disguise to resist the impact of water flow; on the other hand, the filter plate or filter screen 7 is tilted toward one end of the water inlet 2 to gather debris at the bottom of the filter plate or filter screen 7, so that the backflushing water flow can flush the debris clean.
[0046] In one embodiment, the channel partition 9 is located at the edge of the sewage outlet and is inclined when closing the channel, so that particles can be prevented from entering the terminal dead water area or retention area during the flushing process.
[0047] In one embodiment, the water outlet end of the cavity 1 is set to be conical, and the rotating axis of the guide plate 5 is located at an obtuse angle and in the middle of the cone of the cavity 1. This facilitates the rotation of the guide plate 5 to close the channel and facilitates the reverse backflow formed after the water flow impacts the guide plate 5.
[0048] In one embodiment, pressure sensors 8 are provided at the water inlet 2 and the water outlet 3, and all drivers are configured as stepper motors and are connected to the same controller together with the pressure sensors 8. In this way, the pressure changes at the inlet and outlet can be detected by the pressure sensors 8 and the controller can be used to automatically backwash the entire filter.
[0049] Finally, it should be noted that, in this document, relationships such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
