[0002] Sewage is generated in daily life and normal industrial processes. Sewage undergoes multiple processes to meet discharge standards. The sewage treatment process requires preliminary filtration to filter out larger impurities in the sewage.

[0003] When filtering sewage, by installing a filter screen in the filtering equipment, impurities in the sewage can be filtered out and the impurities can flow into the filtering equipment. When a certain amount of impurities accumulate inside the filtering equipment, it is necessary to clean out the impurities inside. However, the existing filtering equipment is not convenient in the process of cleaning impurities. At the same time, some impurities are adsorbed on the outer wall of the filter screen, which is inconvenient to clean, and further affects the sewage filtering process. For this reason, we propose a filtering structure and water treatment equipment. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0022] See also Figure 1-4 The present application provides a filtering structure, including a box body 10 with a sewage outlet at the bottom, a backflushing mechanism 20 that rotates and penetrates the top of the box body 10, a filter cartridge 30 is fixedly sleeved on the backflushing mechanism 20, a discharge mechanism 40 is installed on the inner wall of the box body 10, the discharge mechanism 40 is connected to the bottom of the filter cartridge 30, and its water outlet end passes through the side wall of the box body 10, specifically, the top of the box body 10 is connected to a sewage inlet pipe, so that the sewage enters the box body 10 through the sewage inlet pipe, and the discharge mechanism 40 is installed on the inner wall of the box body 10, and an impurity temporary storage area is formed on the top, so that the sewage passes through the filter cartridge 30, and then the impurities are filtered on the discharge mechanism 40, and the filtered sewage enters the discharge mechanism 40 connected to the filter cartridge 30. When the impurities filtered inside the box body 10 are discharged, the backflushing mechanism 20 rotates, and at the same time drives the filter cartridge 30 to rotate and sprays backflushing water into the filter cartridge 30, so as to clean the impurities adsorbed on the outer wall of the filter cartridge 30. At the same time, when the filter cartridge 30 rotates, the outlet of the discharge mechanism 40 is opened, and the impurities can fall downward through the outlet and be discharged from the sewage outlet at the bottom of the box body 10, so as to facilitate the discharge of impurities inside the box body 10.

[0023] See Figure 1 The backwash mechanism 20 includes a backwash pipe 210 that rotates and passes through the top of the box body 10. The top of the backwash pipe 210 is connected to the water inlet pipe 220, and a plurality of water outlet holes 230 are opened on the outer wall of the backwash pipe 210. The filter cartridge 30 is fixedly mounted on the water inlet pipe 220. When set, the water inlet pipe 220 is connected with the existing conveying device, and then the backwash water is transported into the backwash pipe 210 through the water inlet pipe 220, so that the water is sprayed from the plurality of water outlet holes 230 to spray on the inner wall of the filter cartridge 30 to clean the impurities adsorbed on the outer wall of the filter cartridge 30.

[0024] See Figure 2The recoil mechanism 20 also includes a motor 240 installed on the top of the box body 10, and the motor 240 is transmission-connected to the recoil tube 210. It should be noted that the driving shaft of the motor 240 is connected to a first spur gear, and a second spur gear is fixedly provided on the recoil tube 210. The first spur gear and the second spur gear are meshed with each other to realize that the motor 240 drives the recoil tube 210 to rotate, thereby driving the filter cartridge 30 to rotate, and through the action of centrifugal force, the impurities adsorbed on the outer wall of the filter cartridge 30 are thrown out. In this embodiment, the transmission connection between the motor 240 and the recoil tube 210 is not limited to the above-mentioned gear transmission structure, but can also be other transmission structures that can enable the motor 240 to drive the recoil tube 210 to rotate, such as a pulley transmission structure.

[0025] See Figure 2 The discharge mechanism 40 includes a partition 410 fixedly mounted on the inner wall of the box body 10. The bottom of the partition 410 is connected to a water outlet pipe 420 that passes through the side wall of the box body 10. The bottom of the filter cartridge 30 is slidably arranged on the partition 410 and is connected to the water outlet pipe 420. Specifically, after the sewage enters the filter cartridge 30, it will flow through the partition 410 and into the water outlet pipe 420. The water outlet pipe 420 is connected to the next sewage treatment process to discharge the filtered sewage to the next treatment process.

[0026] See Figure 3 and 4 , a plurality of discharge ports 430 are provided on the partition 410, and a plurality of baffles 310 are fixedly installed on the outer wall of the filter cartridge 30, and the plurality of baffles 310 respectively block a plurality of discharge ports 430. In the specific setting, the baffles 310 are used to block the discharge ports 430 so that when filtering sewage, sewage will not flow through the discharge ports 430. When cleaning impurities on the partition 410, the backflush pipe 210 drives the filter cartridge 30 to rotate, and the filter cartridge 30 drives the baffle 310 to rotate, thereby causing the discharge ports 430 to be intermittently opened, so that impurities can pass through the discharge ports 430 to the bottom of the box body 10 and then be discharged from the sewage outlet at the bottom of the box body 10. Furthermore, the intermittent opening of the discharge ports 430 can prevent the sewage outlet at the bottom of the box body 10 from being blocked, so that the discharge amount each time is constant. In addition, the bottom of the box body 10 is conical, so as to facilitate the discharge of internal impurities.

[0027] See Figure 3 and 4A scraper 110 is fixedly mounted on the inner wall of the box body 10. The scraper 110 is in sliding contact with the top of one of the baffles 310, and one side thereof is flush with the side wall of the discharge port 430. The discharge port 430 is staggered with the water outlet pipe 420. A through hole connected to the water outlet pipe 420 is provided at the bottom of the filter cartridge 30. When set, the baffle 310 rotates, and the scraper 110 can scrape off impurities thereon, and then make the impurities fall into the discharge port 430, so as to achieve the purpose of cleaning the impurities in the box body 10. At the same time, the water outlet pipe 420 is staggered with the discharge port 430, thereby preventing impurities from falling on the water outlet pipe 420.

[0028] A water treatment device comprising

[0029] The above-mentioned filtering structure.

[0030] When the present filtering structure and water treatment equipment are in operation, sewage is transported into the housing 10. After the sewage enters the housing 10, it flows through the filter cartridge 30, filters impurities through the filter cartridge 30, and then flows into the outlet pipe 420. The impurities will accumulate on the partition 410. When the impurities accumulate to a certain amount, the sewage filtration is stopped, and the motor 240 is started at the same time. Backwash water is transported into the backwash pipe 210 through the water inlet pipe 220. In the process of the backwash pipe 210 driving the filter cartridge 30 to rotate, water is sprayed onto the inner wall of the filter cartridge 30 through the water outlet hole 230 to clean the impurities adsorbed on the outer wall of the filter cartridge 30. In addition, the filter cartridge 30 will drive the baffle 310 to open, thereby making the discharge port 430 intermittently open to achieve the purpose of discharging impurities. After the impurities are discharged, the baffle 310 is blocked to block the discharge port 430, and filtration can be carried out again.

[0031] It should be noted that the specific model and specifications of the motor 240 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0032] The power supply and principle of the motor 240 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
