Description
Technical Field
[0001] The utility model provides a water flow guiding mechanism with a filtering structure, belonging to the technical field of water conservancy engineering. Background Art
[0002] Water conservancy and hydropower engineering focuses on the basic knowledge and skills of water resources, hydraulic structures, hydraulics and fluid dynamics, and water conservancy engineering technology. The discipline conducts the survey, planning, design, construction, and management of water conservancy and hydropower projects. Water flow is primarily directed through pipes, a daily necessity used by millions of households.
[0003] The water flow guiding pipes currently used can basically meet normal use needs. In order to filter the water flow while guiding the water flow, the most common method is to directly add a filter plate in the pipe. Although this can achieve good filtering work, after a period of use, a certain amount of impurities are easily retained and attached on the filter plate set between the inner walls of the pipe and cannot be removed. It is usually necessary to stop the water flow guidance and then remove the filter plate from the pipe to remove the impurities. This is not flexible and convenient to use, and is not conducive to removing impurities on the filter plate. In addition, while guiding the water flow, there is a lack of a suitable countercurrent structure. Once the water flow reverses and backflows, the impurities on one side of the filter plate will flow back to various places in the pipe, or even back to the water source, and the filtering effect needs to be improved. Based on this, the utility model provides a water flow guiding mechanism with a filtering structure. Utility Model Content
[0004] The technical problem solved by the utility model is that: when only a filter plate is added to the pipeline to filter and guide the water flow, it is usually necessary to stop the water flow guidance and then take the filter plate out of the pipeline to remove impurities. The use is not flexible and convenient, and is not conducive to removing impurities on the filter plate. In addition, when the water flow reverses, the impurities on one side of the filter plate will reverse and flow back, and the filtering effect needs to be improved.
[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a water flow guiding mechanism with a filtering structure, including a main water inlet pipe, a three-way valve 1 is provided on one side of the main water inlet pipe, a connected filter box is provided at one side outlet of the three-way valve 1, a connected three-way valve 2 is provided on the other side of the filter box, a connected backflow pipe is provided between the three-way valve 1 and the three-way valve 2, a plurality of filter plates are equidistantly inserted in the filter box for sliding, an anti-backflow component is provided in the filter box, and the anti-backflow component includes a mounting plate fixedly arranged on the inner wall of the filter box, a water outlet is provided in the center of the mounting plate, and an anti-backflow plate is provided on the side of the mounting plate close to the filter plate.
[0006] Furthermore, the anti-backflow component is arranged on a side close to the main water inlet pipe, and the anti-backflow component also includes a hollow rod symmetrically arranged on the side wall of the mounting plate away from the filter plate, and a slide is slidably connected inside the hollow rod, and a connecting rod passing through the mounting plate is provided between one side wall of the slide and the side wall of the anti-backflow plate, and a reset spring is provided between the other side wall of the slide and the inner wall of the hollow rod.
[0007] Furthermore, both side walls of the filter box are provided with connection ports connected to three-way valve 1 and three-way valve 2, and one side outlet of the three-way valve 2 is provided with a main water outlet pipe placed on one side of the filter box.
[0008] Furthermore, the filter plate includes a screen frame, a filter arranged on the inner side of the screen frame, a baffle arranged on a side wall of the screen frame, and a handle arranged on the side wall of the baffle. Limit rails matching the inner wall of the filter box are symmetrically provided on both sides of the screen frame.
[0009] Furthermore, the mesh diameters of the plurality of filter plates decrease in sequence, and the mesh diameter of the filter plate closest to the main water inlet pipe is the largest.
[0010] Furthermore, a plurality of impurity discharge ports are equidistantly provided at the bottom of the filter box and are located on a side of the filter plate close to the main water inlet pipe, and a control valve is provided on the impurity discharge port.
[0011] Beneficial effects of the utility model:
[0012] By turning three-way valve one and three-way valve two, the water flow direction is changed to flow in the reverse direction from the counterflow pipe into the filter box. The counterflow water reversely flushes the filter plate, which can flush out impurities trapped on the filter plate near the side wall of the main water inlet pipe. Open the control valve, and the impurities are discharged from the discharge port along with the water, which is conducive to removing impurities on the filter plate. There is no need to stop the water flow guidance and then take out the filter plate to remove impurities. It is more flexible and convenient to use. Under the action of the anti-backflow component, when reverse backflow is carried out, the anti-backflow plate is reversed and reset to the initial state that is tightly fitted with the side wall of the mounting plate, thereby effectively avoiding the backflow during water flow guidance, and effectively preventing impurities from reversely flushing into the three-way valve one and the main water inlet pipe, thereby greatly improving the filtering effect.

Under the action of the multiple filter plates 6 arranged in sequence in the filter box 3, the water flow is filtered layer by layer when passing through the multiple filter plates 6.
[0023] According to the attached Figure 2 、 3As shown: a connected countercurrent pipe 5 is provided between the three-way valve 1 2 and the three-way valve 2 4, and a plurality of impurity discharge ports 21 are equidistantly provided at the bottom of the filter box 3 and are located on the side of the filter plate 6 close to the main water inlet pipe 1. A control valve is provided on the impurity discharge port 21. By operating and screwing the three-way valve 1 2 and the three-way valve 2 4, the water flow direction at this time is changed to: the main water inlet pipe 1, the three-way valve 1 2, the countercurrent pipe 5, the three-way valve 2 4, the connecting port 15, and the filter box 3, so that the water flows in the reverse direction into the filter box 3, and the countercurrent water reversely flushes the filter plate 6, which can flush away impurities trapped on the side wall of the filter plate 6 close to the main water inlet pipe 1.

By holding the handle, the filter plate 6 can be pulled out from the filter box 3, and replacement and maintenance operations can be conveniently realized.
[0026] Principle of the utility model

By screwing the three-way valve 1 2 and the three-way valve 2 4, the water flow guide is changed to flow in the reverse direction from the countercurrent pipe 5 to the filter box 3. The reverse flow of water flushes the filter plate 6 in the reverse direction, which can flush out the impurities trapped on the side wall of the filter plate 6 near the main water inlet pipe 1. Open the control The valve is controlled, and impurities are discharged from the discharge port 21 along with the water, which is conducive to removing impurities on the filter plate 6. There is no need to stop the water flow guidance and then take out the filter plate 6 to remove impurities. It is more flexible and convenient to use. Under the action of the anti-backflow component 7, when reverse backflow is carried out, the anti-backflow plate 10 is reversed and reset to the initial state that is tightly fitted with the side wall of the mounting plate 8, thereby effectively avoiding the backflow during water flow guidance, and when the backflow flushes the filter plate 6, it can effectively prevent impurities from reversely flushing into the three-way valve 2 and the main water inlet pipe 1, and the filtering effect is greatly improved.
