Description

Technical Field

[0001] The utility model relates to the technical field of domestic water treatment, in particular to a domestic sewage purification treatment device. Background Art

[0002] Domestic sewage is a large amount of sewage generated in the daily life of residents. The direct discharge of these sewage has a great impact on the environment and polluted groundwater resources. Now the country's requirements for sewage discharge are becoming more and more stringent. The sewage generated in life must be treated before it can be discharged. In the domestic sewage detection system, because feces and washing water contain more solid particles and dirt, the pipes are easily blocked, and the sewage ferments in the pipes to produce odor.

[0003] In rural areas or some families with independent households, domestic sewage is usually discharged directly and cannot be reused. In most cases, surface water or shallow groundwater is used. The water quality of these waters is usually poor, and long-term direct use will affect health. Some existing household water purification equipment has the problems of inconvenient maintenance and low filtration efficiency. Based on this, we propose a domestic sewage purification device.

[0020] The working principle of the above technical solution is as follows: when in use, by connecting the water inlet pipe 10 to the water flow inlet end, connecting the connecting pipe 5 to the water flow use end, and starting the pressure pump 11, the water flows into the interior of the tank body 1 through the diversion of the water guide pipe 9, and first passes through the primary filter plate 25 and the secondary filter plate 16 to filter larger particles separately. The primary filter plate 25 can filter larger visible objects such as stones or branches, and the secondary filter plate 16 can filter smaller visible particles such as gravel or debris. Then the water flows into the branch pipe 13 under the diversion effect of the diversion cone 15. At this time The water flows through the spiral drainage rotation of the threaded plate 14 and is evenly discharged from the branch pipe 13 under the guidance of the water outlet 18. At this time, it passes through the hollow water purification filter element 19 to filter very small particles, and then passes through the activated carbon purification cartridge 20 and the semi-permeable membrane purification cartridge 21 to filter the water flow to the drinkable standard. Finally, the pressure of the water flow is applied by the pressure pump 11 and discharged and collected through the outlet pipe 12 and the connecting pipe 5. The overall filtering efficiency from bottom to top is stable, which is convenient for reducing blockages caused by filtering accumulation. The equipment can be used for the treatment of domestic sewage and groundwater surface and layer water, and has a wide adaptability.

[0021] In another embodiment, Figure 1-Figure 4 As shown, a sealing gasket is provided at the connection between the support ring 2 and the cover plate 4, and the cover plate 4 is fixed to the top of the tank body 1 by bolts penetrating the support ring 2.

[0022] The cover plate 4 can be removed by removing the bolts during maintenance, and the branch pipe 13, the hollow water purification filter element 19, the activated carbon purification core 20, the semi-permeable membrane purification core 21 and the hollow metal support ring 22 can be taken out respectively, which is convenient for cleaning and replacement, thereby increasing the convenience of maintenance.

[0023] In another embodiment, Figure 3 and Figure 4 As shown, the water outlet holes 18 are spirally threaded and evenly staggered with the threaded plates 14 and distributed inside the branch pipe 13 , and the top end of the branch pipe 13 is a closed structure.

[0024] The arrangement of the water outlet 18 and the threaded plate 14 can improve the flow efficiency of the water flow and evenly disturb the particles in the water flow, thereby avoiding the situation where the filter position is seriously blocked due to accumulation filtration, and stabilizing the filtration efficiency.

[0025] In another embodiment, Figure 3 and Figure 4 As shown, there are two separation rings 23 , and the two separation rings 23 are fixedly mounted on opposite sides of the rubber pad 24 and the partition plate 26 , respectively.

[0026] The setting of the separation ring 23 divides the hollow water purification filter element 19 and the activated carbon purification cartridge 20, which is convenient for subsequent filtration and maintenance and disassembly, and is convenient for adding a water storage space, facilitating filtration, and stabilizing the installation position.

[0027] In another embodiment, Figure 3 and Figure 4 As shown, the specifications and dimensions of the rubber pad 24 are compatible with the specifications and dimensions of the top of the tank body 1, and the specifications and dimensions of the rubber pad 24, the branch pipe 13, the hollow water purification filter element 19, the activated carbon purification core 20, the semi-permeable membrane purification core 21 and the hollow metal support ring 22 are all compatible, and the position of the rubber pad 24 corresponding to the perspective window 3 is set to a transparent rubber material.

[0028] The rubber pad 24 can exert a soft elastic force and compression force on the top of the branch pipe 13, the hollow water purification filter element 19, the activated carbon purification core 20, the semi-permeable membrane purification core 21 and the hollow metal support ring 22, so as to stabilize the position and seal the top at the same time, thereby increasing the overall position effect, and cooperating with the position of the perspective window 3 for observation. In the actual production product specifications, the perspective window 3 can be horizontally arranged on the front of the tank body 1 to facilitate observation of the internal filtration conditions, thereby increasing the overall filtration stability and convenience.

[0029] In another embodiment, Figure 3 and Figure 4 As shown, the secondary filter plate 16 is located on the top of the primary filter plate 25, the three guide pipes 8 are evenly distributed in an alternating symmetry with the secondary filter plate 16 and the primary filter plate 25, the water guide pipe 9 passes through the bottom of the tank body 1 and is connected to the bottom of the primary filter plate 25, and the top of the guide cone 15 is connected to the top of the partition 26.

[0030] This arrangement facilitates the diversion of water flow, increases the pressure and flow of water flow, and by opening the valve 7, the diversion pipe 8 can be connected to the water pump pipe to flush the bottom of the inner cavity of the tank body 1. At this time, the filtered matter deposited on the opposite sides of the primary filter plate 25 and the secondary filter plate 16 can be discharged along the diversion pipe 8 at the other end under the impact of the water flow, which is convenient for overall cleaning and maintenance, makes it easy to use, and indirectly increases the service life.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
