Description

Technical Field

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

[0002] A highway service area refers to a place specifically for passengers and drivers to stop and rest. It should provide parking lots, public toilets, gas stations, vehicle repair shops, restaurants and canteens and other facilities. The average spacing is about 50 kilometers, and the scale of service area construction must be able to adapt to the future growth in traffic volume.

[0003] Due to the coming and going of people, and most of them eat in the service area, a lot of sewage is generated in the service area. If the sewage is discharged directly, it will pollute the environment. Therefore, the sewage needs to be treated before being discharged. When the existing highway service area sewage treatment and purification device treats the sewage, due to the presence of a large number of plastic bags, waste boxes and other debris in the sewage, it is easy to cause the sewage treatment and purification device to be blocked, thereby affecting the normal use of the sewage treatment and purification device. Most of the existing sewage treatment and purification devices are not convenient for cleaning up the debris, which makes the sewage treatment and purification device inconvenient to use.

[0004] After searching, the existing patent: A domestic sewage treatment and purification device (application number: CN202221452475.0) includes a box body, a cavity is opened in the box body, a turntable is rotatably provided in the cavity, the turntable is located at the upper part of the cavity, a plurality of filter screens are fixedly embedded in a circular array on the turntable, a through groove is opened through the middle part of one side of the box body, the through groove is communicated with the internal space of the cavity, a rotating shaft is rotatably provided on the inner wall of the bottom end of the through groove, a rotating column is fixedly sleeved on the rotating shaft, a shell matching the cavity is fixedly connected to the side of the rotating column close to the cavity, a filter screen 2 is fixedly provided on the bottom end of the shell, and an activated carbon layer, a sand and gravel layer and a sponge layer are fixedly provided on the lower inner wall of the cavity. The utility model can facilitate the cleaning of plastic bags, waste boxes and other debris in the device, thereby avoiding affecting the normal use of the sewage treatment and purification device.

[0005] Although the above patent can facilitate the cleaning of plastic bags, waste boxes and other debris in the device, thereby avoiding affecting the normal use of the sewage treatment purification device, when the device is used for a long time, due to the presence of a large amount of impurities and dirt in the sewage, the impurities and dirt can easily clog the filter during long-term filtration, thereby reducing the purification effect of the device. At the same time, it is inconvenient for users to clean the filter, which makes the device have certain limitations during use and is not convenient for users to use. Therefore, it is necessary to invent a domestic sewage purification treatment device to solve the above problems. Utility Model Content

[0026] A water inlet valve 4 is installed at the top of the water inlet pipe 3, and by connecting the water inlet pipe 3 to the sewage pipe, when the sewage needs to be purified, the water inlet valve 4 at the top of the water inlet pipe 3 can be opened to discharge the sewage through the water inlet pipe 3 into the interior of the purification box body 1 for sewage purification.

[0027] Handles 5 are provided at both ends of the cover plate 2. By installing two sets of handles 5 at both ends of the cover plate 2, when it is necessary to clean or inspect the inside of the purification box body 1, the cover plate 2 can be lifted upward by holding the two sets of handles 5, which is convenient for the user to clean or inspect the inside of the purification box body 1.

[0028] A cleaning scraper 9 is fixed to the bottom end of the motor drive shaft 8. During the sewage purification process, when the sewage enters the purification box body 1 through the water inlet pipe 3, it will first pass through the filter 6. During use, the drive motor 7 can be turned on to rotate the motor drive shaft 8, and then the cleaning scraper 9 at the bottom of the motor will rotate synchronously with the filter 6 under the rotation of the motor drive shaft 8. The dirt and impurities attached to the filter 6 are pushed to the inside of the storage box 10 by the cleaning scraper 9, which is convenient for centralized treatment and avoids clogging of the filter 6 during long-term use.

[0029] A fixing rod 11 is installed inside the storage box 10. When impurities and dirt inside the storage box 10 need to be cleaned, the cover 2 can be lifted up, and then the storage box 10 can be taken out from the inside of the installation groove 12 by holding the two sets of fixing rods 11, which is convenient for the user to carry out centralized processing.

By setting up two groups of filter materials 13, the filtering effect is better. At the same time, when the filter material 13 needs to be replaced, the filter material 13 can be pulled out from the inside of the purification box body 1 by pulling the connecting plate 15, which is convenient for the user to replace.

[0031] A water outlet valve 18 is installed at one end of the water outlet pipe 17 , and the filtered and purified water can be discharged from the water outlet pipe 17 by opening the water outlet valve 18 .

[0032] Working principle: When the domestic sewage purification treatment device is used, the water inlet pipe 3 is connected to the sewage pipe. When the sewage needs to be purified, the water inlet valve 4 at the top of the water inlet pipe 3 can be opened to discharge the sewage into the interior of the purification box body 1 through the water inlet pipe 3. When the sewage enters the interior of the purification box body 1 through the water inlet pipe 3, it will first pass through the filter 6. During use, the drive motor 7 can be turned on to make the motor drive shaft 8 rotate, and then the cleaning scraper 9 at the bottom of the motor will rotate synchronously with the filter 6 under the rotation of the motor drive shaft 8. The dirt and impurities attached to the filter 6 are pushed to the inside of the storage box 10 by the cleaning scraper 9, which is convenient for centralized treatment and avoids the filter 6 from being used for a long time. If blockage occurs during the process, when it is necessary to clean the impurities and dirt inside the storage box 10, the cover plate 2 can be lifted upwards, and then the storage box 10 can be taken out from the inside of the installation groove 12 by holding the two sets of fixing rods 11, which is convenient for the user to carry out centralized treatment. When the sewage passes through the filter screen 6, it will enter the filter material 13, and multiple sets of filter materials 13 are fixed and installed through the connecting rods 14. The sewage is purified again by multiple sets of filter materials 13. By setting two sets of filter materials 13, the filtering effect is better. At the same time, when the filter material 13 needs to be replaced, the filter material 13 can be pulled out from the inside of the purification box body 1 by pulling the connecting plate 15, which is convenient for the user to replace. At the same time, the filtered and purified water can be discharged from the outlet pipe 17 by opening the outlet valve 18.
