Description

Technical Field

[0001] The utility model belongs to the technical field of drinking water filtration, and particularly relates to a safe drinking water filtration device. Background Art

[0002] Rural drinking water generally comes from reservoirs, rivers, lakes, springs, cellar water or wells. Before being transported to residents' homes, it often needs multiple filtrations and disinfections due to impurities and microbial contamination. In the primary filtration stage, since there are a large number of suspended substances and large particles in the water, the removal of these impurities is crucial for subsequent filtration.

[0003] However, there are certain deficiencies in the existing primary filtration devices during use: 1. It is difficult to continuously filter the water flow. After being used for a period of time, the filter screen is prone to clogging, affecting the filtration efficiency; 2. It only has basic filtration functions and cannot assist in killing microorganisms in the water, and there is still a great pressure on subsequent disinfection and killing. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a safe drinking water filtration device, and the technical solutions adopted are as follows:

[0005] A safe drinking water filtration device includes a bottom box. Above the bottom box, there is a circular filter cylinder. Inside the filter cylinder, there is a circular filter screen. On one side of the filter cylinder, there is a cylinder cover, and an inlet pipe and a sewage discharge pipe are arranged in the cylinder cover; on the other side of the filter cylinder, there is a mounting plate. Outside the mounting plate, there is a driving motor, and the driving motor is connected to the filter screen through a connecting rod. There are multiple scraping plates inside the filter screen;

[0006] Below the filter cylinder, there is a square opening. At the opening, there is a connecting cylinder. The upper end of the connecting cylinder is in contact with the outer surface of the filter screen. At the lower end of the connecting cylinder, there is a partition plate. On both sides of the partition plate, there are cover plates respectively. Inside the cover plates, disinfection lamps are installed. A gate is installed in the connecting cylinder. Above the partition plate and on both sides of the connecting cylinder, there is a telescopic cylinder connected to the gate respectively.

[0007] Further, bearings for supporting the filter screen are respectively arranged at both ends of the filter screen. Under the support of the bearings, the filter screen can rotate smoothly.

[0008] Further, a blocking plate is arranged at one end of the inner side of the filter screen close to the driving motor. The connecting rod is connected to the blocking plate. The driving motor can drive the filter screen to rotate through the connecting rod, realizing the replacement of the filtering area in the filter screen and the overall cleaning of the filter screen. When the filter screen is cleaned, the rotation speed exceeds 500 revolutions per minute, which can drive the water flow inside the filter cylinder to rotate. The rotating water flow will impact towards the filter screen under the action of the arc-shaped plate on the inner wall of the filter cylinder, which can effectively remove the impurities on the surface of the filter screen and avoid clogging of the filter screen.

[0009] Furthermore, a moving groove for the sliding of the gate is provided inside the connecting cylinder, which can maintain stability when the gate moves.

[0010] Furthermore, a water outlet pipe is provided at the bottom of the bottom box, and a controller is provided outside the bottom box. The controller precisely regulates the operation of the drive motor, the telescopic cylinder and the disinfection lamp through a preset program. The cover plate below the disinfection lamp is a transparent acrylic plate, which can make the light of the disinfection lamp fully irradiate into the bottom box to thoroughly disinfect the water source in the bottom box and further ensure the water quality safety.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] With the rotatable filter screen and the connecting cylinder attached below the filter screen, the utility model can effectively intercept impurities while also extending the service life of the filter screen, reducing the maintenance and cleaning frequency. When the filter screen needs to be cleaned, only the drive motor needs to be driven to drive the filter screen to rotate rapidly. During the rotation of the filter screen, the water flow will be driven by the scraper inside the filter screen to rotate, thus forming a vortex, and the arc-shaped plate is used to guide the water flow to wash the surface of the filter screen, so as to achieve the cleaning of the filter screen. The cleaned sewage can be quickly discharged through the sewage pipe to ensure the hygiene and efficient operation of the entire filtration system.

[0013] The bottom box of the utility model is divided into independent spaces by the partition plate and the cover plate. The disinfection lamp and the telescopic cylinder are both located in the independent space, not affected by the water flow in the bottom box. At the same time, the disinfection lamp irradiates through the cover plate to continuously disinfect the water source in the bottom box, effectively preventing the growth of bacteria and ensuring the water quality safety.

[0027] As shown in the appended Figure 1 - appended Figure 10 drawing

[0028] A safe drinking water filtering device includes a bottom box 1. Above the bottom box 1, there is a circular filter cylinder 2. Inside the filter cylinder 2, there is a circular filter screen 3. At both ends of the filter screen 3, there is a bearing 25 for fixing the filter screen 3 respectively. Based on this structure, the filter screen 3 can rotate stably inside the filter cylinder 2

[0029] On one side of the filter cylinder 2, there is a cylinder cover 21. The cylinder cover 21 is provided with a water inlet pipe 26 and a sewage pipe 27; on the other side of the filter cylinder 2, there is a mounting plate 22. Outside the mounting plate 22, there is a driving motor 23. The driving motor 23 is connected to the filter screen 3 through a connecting rod 24; specifically, at one end of the inner side of the circular filter screen 3 close to the driving motor 23, there is a plug plate, and the connecting rod 24 is connected to the plug plate

[0030] Based on the above structure, the filter screen 3 is driven to rotate by the driving motor 23, as shown in the appended Figure 4As shown, both the water inlet pipe 26 and the sewage discharge pipe 27 in the filter cartridge 2 are connected to the inner side of the filter cartridge 2.

[0031] A square opening is provided below the filter cartridge 2, and a connecting cylinder 4 is provided at the opening. The upper end of the connecting cylinder 4 is in contact with the outer surface of the filter screen 3. A partition plate 5 is provided at the lower end of the connecting cylinder 4. An arc-shaped cover plate 51 is provided on both sides of the partition plate 5. A disinfection lamp 6 is installed inside the cover plate 51, which can effectively disinfect the water source in the bottom box 1.

[0032] A gate 7 is installed in the connecting cylinder 4. On both sides of the connecting cylinder 4 above the partition plate 5, a telescopic cylinder 8 connected to the gate 7 is provided respectively. Through the telescopic action of the telescopic cylinder 8, the opening and closing of the gate 7 can be controlled. A moving groove 41 for the gate 7 to slide is provided inside the connecting cylinder 4 to ensure the accurate positioning of the gate 7; the structural design of the partition plate 5 and the cover plate 51 makes an independent sealed space formed above the partition plate 5 to prevent water flow from entering and ensure the normal operation of the telescopic cylinder 8 and the disinfection lamp 6.

[0033] A water outlet pipe 11 is provided at the bottom of the bottom box 1, and a controller 12 is provided outside the bottom box 1. The controller 12 accurately regulates the working states of the driving motor 23, the telescopic cylinder 8 and the disinfection lamp 6 through a preset program.

[0034] Based on the above structure, the usage process is as follows: The external water source enters the filter cartridge 2 through the water inlet pipe 26 and flows into the bottom box 1 through the connecting cylinder 4. Before the water flow passes through the connecting cylinder 4, the water flow will pass through the filter screen 3 above the connecting cylinder 4, which can intercept impurities and suspended matters in the water.

[0035] After working for a period of time, the filter screen 3 can rotate a certain angle driven by the driving motor 23 to replace the filter screen area above the connecting cylinder 4, so as to continue to intercept impurities and ensure the continuous high efficiency of the filtering effect.

[0036] When the filter screen 3 needs to be cleaned at all filter screen areas after rotating one week, the gate 7 is closed by the telescopic cylinder 8, and then the filter screen 3 rotates rapidly driven by the driving motor 23. There are 2 - 3 scraping plates 31 inside the filter screen 3. During the rotation of the filter screen 3, the water flow in the filter cartridge 2 is driven by the scraping plates 31 inside the filter screen 3 to form a vortex. Further, a plurality of arc-shaped plates 28 are provided on the inner wall of the filter cartridge 2. The rotating water flow outside the filter screen 3 can wash the surface of the filter screen 3 under the guidance of the arc-shaped plates 28, so that the impurities on the surface of the filter screen 3 are all thrown into the inside of the filter screen 3, and then can be discharged through the sewage discharge pipe 27, thus realizing the overall cleaning of the filter screen 3.

[0037] After cleaning, close the sewage drain pipe 27, open the water inlet pipe 26, and then reopen the gate 7 through the telescopic cylinder 8, and the filter screen 3 can resume its working state. Through this efficient cleaning mechanism, the filter screen 3 can always maintain the best filtering state to ensure pure water quality. Further, according to the preset program, the controller 12 can start the disinfection lamp 6 regularly. The cover plate 51 is made of transparent acrylic board, which can make the light of the disinfection lamp 6 fully irradiate into the bottom box 1 to thoroughly disinfect the water source in the bottom box 1, further ensuring water quality safety.

[0038] Any technical solution using the technical solution of the present invention or designed by those skilled in the art inspired by the technical solution of the present invention to achieve the above technical effects shall fall within the protection scope of the present invention.
