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, the traditional Y-shaped filter is a small device that removes a small amount of solid particles from the liquid, which can protect the normal operation of the equipment. When the fluid enters the filter cartridge with a filter screen of a certain specification, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. When cleaning is required, just take out the detachable filter cartridge, treat it and reinstall it. Therefore, it is extremely convenient to use and maintain. However, the traditional Y-shaped filter usually has an independent filter screen set in the filter body. After using the Y-shaped filter for a period of time, it is necessary to regularly open the sealing end cover on one side of the Y-shaped filter, take out the filter screen for cleaning and maintenance to ensure that the Y-shaped filter will not be blocked during subsequent use. For some larger pipes and valves, it is inconvenient to clean by removing the filter screen, which is time-consuming and labor-intensive, and has 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, which discloses a filter including a first filter channel and a second filter channel, both ends of the first filter channel and the second filter channel are connected with a Y-type connector, one end of the Y-type connector is connected with a flange, both ends of the first filter channel and the second filter channel are respectively provided with an inlet valve and an outlet valve, and filter screens are installed inside the first filter channel and the second filter channel. A recoil 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, and 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 recoil plate, a drain port, and a micro high-pressure water pump, which can automatically flush the surface of the filter screen by backwashing, so that impurities fall off the surface of the filter screen and are discharged from the drain port. 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 sounded to remind you so that the filter can be cleaned in time.

[0004] The prior art 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, when the water inlet valve is not closed, the high-pressure water pump is required to provide a larger pressure to achieve backflushing. If the water inlet valve is closed, an additional new water source is required for re-flushing. Therefore, 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 view of 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 in conjunction with the accompanying drawings.

[0036] like Figures 1 to 6 A self-exhausting filter is shown, comprising: a cavity 1, the filter cavity of the present application is set to be square, one end of the cavity 1 is configured with a water inlet 2, the other end is configured with a water outlet 3, the middle of the cavity 1 is configured with a central partition 4 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; the bottom of the first channel 12 and the second channel 13 is configured with a sewage outlet 11, and the channel of the sewage outlet 11 is provided with a filter plate or a filter screen 7; and

[0037] Guide plate 5, square baffle 6, channel baffle 9, sewage baffle 10, first driver 51, second driver 61, third driver 91, fourth driver 101;

[0038] Among them, the guide plate 5 is transfer-arranged at the intersection of the Y-shaped channels at one end of the water outlet 3, the square baffle 6 is transfer-arranged at the intersection of the Y-shaped channels at one end of the water inlet 2, the first driver 51 is arranged outside the cavity 1 and drives the guide plate 5 to rotate to open and close the two channels, the second driver 61 is arranged outside the cavity 1 and drives the square baffle 6 to rotate to open and close the two channels, a channel partition plate 9 is transfer-arranged in the first channel 12 and the second channel 13 respectively, the third driver 91 is arranged outside the cavity 1 and drives the channel partition plate 9 to rotate to open and close the channels, the sewage baffle 10 is transfer-arranged at the sewage outlet 11, and the fourth driver 101 is arranged outside the cavity 1 and drives the sewage baffle 10 to rotate to open and close the sewage outlet 11.

[0039] When the present application is working, the square baffle 6 rotates to one side to close one of the two channels, the channel partition 9 in the closed channel rotates to separate the channel again, and the sewage baffle 10 rotates to open the sewage outlet to prepare for sewage discharge. At the same time, the clean water filtered from the other channel is blocked by the guide plate 5 and then flows back to the filter plate or filter screen 7 on the other channel to achieve non-stop reverse flushing of the filter plate or filter screen 7. In this way, the two channels are circulated to achieve backwashing of the two 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 the water 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 and a sewage baffle 10 for controlling the sewage outlet 11 are set on each channel to open and close the sewage outlet 11 in conjunction with the channel partition 9 of the equipment inside the channel to realize backwashing. The characteristic that backflow will be formed after water flow and obstruction is used to set a filter plate or 7 and a corresponding sewage outlet 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 corresponding baffle to rotate and open and close to realize the 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, a corner of the guide plate 5 facing the water outlet 3 is set to 120 degrees, and the corner faces the central partition 4 to facilitate the opening and closing of the two channels and the blocking of the backflow to form a 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 chamber 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 backwash water flow can rinse 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 rotation 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 reflux 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 sensor 8 can detect the pressure changes at the inlet and outlet ends and jointly with the controller to realize automatic backwashing of the entire filter.
