Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a filter valve for water treatment. Background Technology

[0002] Water treatment filter valves are key devices for intercepting impurities in water. Their core functions are filtration and sewage discharge. After prolonged use, a large amount of impurities accumulate on the filter screen of the filter valve, which needs to be cleaned in time. Otherwise, the filter screen will become clogged, affecting the normal operation of the filter valve.

[0003] The backwash filter valve can discharge sewage by changing the direction of water flow, driving clean water to backwash the filter screen and discharge contaminants from the dedicated drain port, thereby cleaning the filter screen and allowing the filter valve to perform filtration operations for a long time.

[0004] Staff discovered that the existing backwash valves have certain defects in use. The existing backwash filter valves rely on an external clean water source to rinse and clean the filter screen and remove impurities. They cannot achieve spontaneous backwash cleaning and sewage discharge, resulting in a waste of clean water. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to propose a filter valve for water treatment, which adopts a dual drain outlet and a rotary stepper design, requiring no external power source, and can automatically complete the backwashing and drainage of the filter plate in steps using only the system's own water pressure.

[0007] To achieve the above objectives, the first aspect of this utility model provides a water treatment filter valve, comprising: a valve body, a flow pipe, a first drain pipe, a second drain pipe, a drive assembly, a backwashing assembly, and a filter plate. The flow pipe is connected to the top of the valve body, with its two ends respectively connected to the top of the valve body. The first drain pipe is disposed between the front and rear ends of the flow pipe and is connected to the bottom of the valve body. The second drain pipe is disposed below the rear end of the flow pipe and is connected to the bottom of the valve body. The drive assembly is disposed on the outside of the valve body. The backwashing assembly is installed inside the valve body and is connected to the drive assembly. The filter plate is disposed between the first drain pipe and the second drain pipe and is fixedly connected to the inner wall of the valve body.

[0008] In addition, the water treatment filter valve proposed above according to this utility model may also have the following additional technical features: Specifically, the backwashing assembly includes a first connecting ring, a first partition mechanism, a second connecting ring, a third connecting ring, and a second partition mechanism, wherein, The first connecting ring is located below the inlet of the flow pipe, and is rotatably connected to the inner wall of the valve body. A connection port is provided on the first connecting ring. The first partition mechanism is installed on the rear side of the first connecting ring. The second connecting ring is disposed above the first drain pipe, and is rotatably connected to the inner wall of the valve body, with a connection interface provided on the second connecting ring. The third connecting ring is disposed above the second drain pipe, and is rotatably connected to the inner wall of the valve body. Two connection ports are provided on the third connecting ring. The second partition mechanism is located on the rear side of the third connecting ring.

[0009] Specifically, the first partition mechanism includes a first partition frame and a first rotating plate, wherein, The first partition frame is disposed between the first connecting ring and the second connecting ring, and the first partition frame is fixedly connected to the inner wall of the valve body.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] A water treatment filter valve according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0026] like Figures 1-10 As shown in the figure, a water treatment filter valve according to an embodiment of the present invention includes: a valve body 1, a flow pipe 2, a first drain pipe 3, a second drain pipe 4, a drive assembly 5, a backwashing assembly, and a filter plate 9.

[0027] It should be noted that the outside of valve body 1 is marked with water flow direction to facilitate the installation of valve body 1 by staff.

[0028] The flow pipe 2 is connected to the top of the valve body 1, and the two ends of the flow pipe 2 are connected to the top of the valve body 1 respectively. The first drain pipe 3 is located between the front and rear ends of the flow pipe 2 and is connected to the bottom of the valve body 1. The second drain pipe 4 is located below the rear end of the flow pipe 2 and is connected to the bottom of the valve body 1.

[0029] It should be noted that the first sewage pipe 3 and the second sewage pipe 4 are respectively connected to the external wastewater tank.

[0030] The sewage discharge assembly is installed inside the valve body 1 and is connected to the drive assembly 5. The filter plate 9 is located between the first sewage pipe 3 and the second sewage pipe 4 and is fixedly connected to the inner wall of the valve body 1.

[0031] It should be noted that the sewage discharge components control the opening and closing of the inlets and outlets of the flow pipe 2, the inlet of the first sewage pipe 3, and the inlet of the second sewage pipe 4, respectively.

[0032] Specifically, under normal filtration conditions, the inlet and outlet of the connecting pipe are closed, as are the inlets of the first drain pipe 3 and the second drain pipe 4. Wastewater is discharged after being filtered through the filter plate 9.

[0033] When sewage needs to be discharged, it first switches to the first sewage discharge state. The front and rear ports of the flow pipe 2 are opened, the space between the front port of the flow pipe 2 and the front side of the filter plate 9 is blocked, the first sewage pipe port is opened, the second sewage pipe port is closed, the space between the rear side of the second sewage pipe and the outlet of the valve body 1 is blocked, sewage flows into the flow pipe 2, to the rear side of the filter plate 9, and through the filter plate 9, the pollutants on the front side of the filter screen are discharged through the first sewage discharge pipe 3.

[0034] The first sewage discharge state is to backwash the filter plate 9 and discharge the impurities on the front side of the filter plate 9. However, since the backwash water used is sewage, it will cause pollutants to appear on the back side of the filter plate 9, so it is necessary to switch to the second sewage discharge state.

[0035] Then it switches to the second sewage discharge state. The front and rear ports of the flow pipe 2 are closed, the space between the front port of the flow pipe 2 and the front side of the filter plate 9 is opened, the first sewage pipe port is closed, the second sewage pipe port is opened, the space between the rear side of the second sewage pipe and the outlet of the valve body 1 is isolated, the sewage passes through the filter plate 9 from the front side of the filter plate 9, and the pollutants on the rear side of the filter plate 9 are discharged through the second sewage discharge pipe 4.

[0036] After the clean water filtered by filter plate 9 discharges the impurities behind filter plate 9, it can switch to the filtration state to prevent impurities from flowing into the clean water pool.

[0037] Finally, it switches back to filtration mode for normal wastewater filtration.

[0038] In one embodiment of this utility model, such as Figures 3-5 As shown, the sewage discharge assembly includes a first connecting ring 6, a first partition mechanism 7, a second connecting ring 8, a third connecting ring 10, and a second partition mechanism 11.

[0039] The first connecting ring 6 is located below the front opening of the flow pipe 2. The first connecting ring 6 is rotatably connected to the inner wall of the valve body 1, and a connection port is opened on the first connecting ring 6.

[0040] Specifically, in the filtering state, the interface on the first connecting ring 6 and the front opening of the flow pipe 2 are 120° apart counterclockwise.

[0041] The first partition mechanism 7 is installed on the rear side of the first connecting ring 6.

[0042] The second connecting ring 8 is located above the first drain pipe 3. The second connecting ring 8 is rotatably connected to the inner wall of the valve body 1, and a connection interface is opened on the second connecting ring 8.

[0043] Specifically, in the filtration state, the interface on the second connecting ring 8 and the port of the first drain pipe 3 are 120° apart counterclockwise.

[0044] The third connecting ring 10 is located above the second drain pipe 4. The third connecting ring 10 is rotatably connected to the inner wall of the valve body 1, and two connection ports are opened on the third connecting ring 10.

[0045] Specifically, the two mating interfaces on the third connecting ring 10 are 60° apart; the mating interface closest to the downstream opening of the flow pipe 2 is 60° apart counterclockwise with respect to the downstream opening of the flow pipe 2; and the mating interface closest to the opening of the second drain pipe 4 is 60° apart clockwise with respect to the opening of the second drain pipe 4. The second partition mechanism 11 is located on the rear side of the third connecting ring 10.

[0046] The first partition mechanism 7 includes a first partition frame 71 and a first rotating plate 72.

[0048] Specifically, the bottom of the first partition frame 71 has a 120° flow port, and the first rotating disk has a 240° flow port.

[0049] The second partition mechanism 11 includes a second partition frame 111 and a second rotating plate 112.

[0050] The second partition frame 111 is located on the rear side of the third connecting ring 10. The second partition frame 111 is fixedly connected to the inner wall of the valve body 1, and the second rotating plate 112 is rotatably connected to the inner side of the second partition frame 111.

[0051] Specifically, the bottom of the second partition frame 111 has a 120° flow port, and the second rotating disk has a 120° flow port.

[0052] It should be noted that the drive assembly 5 includes a motor, a rotating shaft and multiple gears. The rotation angle and rotation speed of the motor can be controlled. The motor is installed in a sealing cover on one side of the valve body 1. The rotating shaft is rotatably connected in the sealing cover, and one end of the rotating shaft is connected to the drive shaft of the motor. Multiple gears are fixedly installed on the outside of the rotating shaft.

[0053] It should be noted that the outer sides of the first connecting ring 6, the first rotating plate 72, the second connecting ring 8, the third connecting ring 10, and the second rotating plate 112 are respectively provided with annular tooth grooves, and the tooth grooves mesh with the corresponding gears.

[0054] It should be noted that mechanical sealing rings are respectively provided between the first connecting ring 6, the first rotating plate 72, the second connecting ring 8, the third connecting ring 10, and the second rotating plate 112 on the inner wall of the valve body 1, in order to maintain the sealing between the sewage discharge component and the inner wall of the valve body 1.

[0055] Specifically, when switching from the filtration state to the first sewage discharge state, the drive assembly 5 drives the first connecting ring 6, the first rotating plate 72, the second connecting ring 8, the third connecting ring 10, and the second rotating plate 112 to rotate 120° clockwise.

[0056] The interface of the first connecting ring 6 is connected to the front port of the flow pipe 2, the flow port of the first partition frame 71 is closed, the interface of the second connecting ring 8 is connected to the port of the first sewage pipe 3, the interface on the third connecting ring 10 is only connected to the rear port of the flow pipe 2, and the flow port of the second partition frame 111 is closed.
