The setting of the blocking ball is added to prevent the guiding rod from getting out of the control range during the movement in the guiding groove, thereby realizing the effect of the upper and lower sealing plug plates approaching and sealing against each other to block, and playing the role of preventing reverse flow;

[0015] 2. In the present utility model, the unloading plate in the inner wall of the commutation box rotates to unload the force under the impact of liquid water. The liquid water is transferred through the inlet pipe and enters the ceramic membrane box body.

The activated carbon filter plate above the first ceramic membrane group plays the role of assisting filtration, ensuring the effect of multi-directional blocking and filtration.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Example 1, please refer to Figures 1 to 6 , the present invention provides a technical solution: a ceramic membrane box, including a ceramic membrane box body 1, a converter box 2 is fixedly connected to the left side of the ceramic membrane box body 1, a main through pipe 3 is fixedly connected to the top of the converter box 2, a feed pipe 4 is fixedly connected to the left side of the main through pipe 3, the top of the inner wall of the main through pipe 3 is connected to a tensile spring 5 through a damping pad, one end of the tensile spring 5 is connected to a sealing gasket 6 through a damping pad, the bottom of the sealing gasket 6 is fixedly connected to an outer rod 7, one end of the outer rod 7 is fixedly connected to a lower sealing plug plate 8, an upper sealing plug plate 9 is fixedly connected to the main through pipe 3 near the middle of its inner wall, the surface of the lower sealing plug plate 8 and the surface of the upper sealing plug plate 9 are in sealing contact, a first ceramic membrane group 10 is fixedly connected to the left side of the inner wall of the ceramic membrane box body 1, a flow diversion pipe 11 is fixedly connected to the left side of the inner wall of the ceramic membrane box body 1, one end of the flow diversion pipe 11 passes through the inside of the first ceramic membrane group 10, and the left side of the flow diversion pipe 11 is connected to the inside of the converter box 2, an activated carbon filter screen plate 12 is fixedly connected to the top of the ceramic membrane box body 1 near its inner wall, left partition plates 13 and right partition plates 14 are fixedly connected to the surface of the inner wall of the ceramic membrane box body 1, a second ceramic membrane group 15 is fixedly installed near the middle of the inner wall of the ceramic membrane box body 1, a third ceramic membrane group 16 is fixedly installed near the right side of the inner wall of the ceramic membrane box body 1, and a drain pipe 17 is fixedly connected to the right side of the ceramic membrane box body 1.

[0025] Furthermore, the main body of the converter box 2 is a sealed box, the inner wall of the sealed box is rotatably connected to a force unloading plate 18 through a bearing, and the force unloading plate 18 rotates and unloads force under the impact of liquid water in the inner wall of the converter box 2.

[0026] Further, an inner rod 19 is fixedly connected to the upper surface of the inner wall of the main pipe 3. The surface of the inner rod 19 is slidably connected to the inner wall of the outer rod 7. The guiding and limiting settings of the inner rod 19 and the outer rod 7 enable the lower sealing plug plate 8 to drive the sealing gasket 6 to lift smoothly.

[0027] Further, both the first ceramic membrane group 10 and the third ceramic membrane group 16 are composed of a plurality of flat ceramic membranes placed horizontally, and the second ceramic membrane group 15 is composed of a plurality of flat ceramic membranes placed vertically. The opening of the left partition plate 13 is located above it, and the opening of the right partition plate 14 is located below it. A sinking groove 23 is formed in the lower surface of the inner wall of the ceramic membrane box body 1. The inner wall of the sinking groove 23 is a smooth surface, and the sinking groove 23 is located directly below the first ceramic membrane group 10. Since both the first ceramic membrane group 10 and the third ceramic membrane group 16 are composed of a plurality of flat ceramic membranes placed horizontally, and the second ceramic membrane group 15 is composed of a plurality of flat ceramic membranes placed vertically, it can block and filter impurities in water in multiple directions. The impurities in the water intercepted by the first ceramic module will fall into the sinking groove 23 for sedimentation and collection of impurities for subsequent cleaning.

[0028] Example 2, please refer to Figures 1 to 6 , the difference between this embodiment and Embodiment 1 is that a guiding rod 20 is fixedly connected to the upper surface of the lower sealing plug plate 8, and a guiding groove 21 is formed inside the upper sealing plug plate 9. The inner wall of the guiding groove 21 is slidably connected to the surface of the guiding rod 20. A blocking ball 22 is fixedly connected to the top end of the guiding rod 20. The circumferential length of the blocking ball 22 is at least greater than the length of the notch of the guiding groove 21, and the blocking ball 22 is located directly above the upper sealing plug plate 9. Through the settings of the guiding rod 20 and the guiding groove 21, the smooth lifting and lowering of the upper sealing plug plate 9 on the lower sealing plug plate 8 is ensured. The addition of the blocking ball 22 can prevent the guiding rod 20 from getting out of the control range during the movement in the guiding groove 21, thereby realizing the effect of the upper sealing plug plate 9 and the lower sealing plug plate 8 approaching each other, sealing and abutting to block, and achieving the effect of preventing backflow.

[0029] Working principle: When using this ceramic membrane box, the staff can install and place the ceramic membrane box body 1 at a suitable filtration position. Liquid water can be introduced through the left feed pipe 4 of the main through pipe 3. The liquid water will first enter the lower part of the sealing gasket 6. The liquid water flowing from above to below will strike the lower sealing plug plate 8 for impact, and the upper sealing plug plate 9 will discharge the liquid water and flow into the lower part, thereby completing the normal outflow and discharge of liquid water. Through the tension spring 5, buffer elastic tension can be carried out for the impact. Due to the guiding and limiting settings of the inner rod 19 and the outer rod 7, the lower sealing plug plate 8 can drive the sealing gasket 6 to lift and lower smoothly. If there is a reverse flow situation during the discharge of liquid water in the main through pipe 3, the liquid water will surge up and lift the lower sealing plug plate 8 close to the upper sealing plug plate 9. Through the settings of the guiding rod 20 and the guiding groove 21, the smooth lifting and lowering of the lower sealing plug plate 8 and the upper sealing plug plate 9 are ensured. The setting of the blocking ball 22 is added to prevent the guiding rod 20 from getting out of the control range during the movement in the guiding groove 21, thereby achieving the effect of the upper sealing plug plate 9 and the lower sealing plug plate 8 approaching and sealing against each other to block, playing an anti-reverse flow effect. Normally, liquid water will enter the flow conversion box 2 through the main through pipe 3. The unloading plate 18 on the inner wall of the flow conversion box 2 rotates and unloads force under the impact of liquid water. The liquid water is transferred through the feed pipe 4 and enters the ceramic membrane box body 1, and is successively filtered multiple times through the first ceramic membrane group 10, the second ceramic membrane group 15, and the third ceramic membrane group 16. Since both the first ceramic membrane group 10 and the third ceramic membrane group 16 are composed of multiple flat ceramic membranes placed horizontally, and the second ceramic membrane group 15 is composed of multiple flat ceramic membranes placed vertically, multi-directional blocking and filtering of impurities in the water can be carried out. The impurities in the water intercepted by the first ceramic module will fall into the sinking tank 23 for sedimentation and collection of impurities for subsequent cleaning. The activated carbon filter plate 12 above the first ceramic membrane group 10 assists in filtering, ensuring the multi-directional blocking and filtering effect and the unloading and anti-reverse flow effect of the incoming water.
