[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people. According to the source of sewage, sewage treatment is generally divided into industrial sewage treatment and domestic sewage treatment.

[0003] When treating sewage, the sewage needs to pass through a sewage treatment interception device to intercept garbage in the sewage before entering the sewage treatment pool to prevent the garbage from affecting the treatment process of the sewage treatment pool. After a long period of use, the interception device will be blocked by solid pollutants. In order not to affect the sewage treatment efficiency, it is necessary to manually go down into the water inlet channel to clean the surface of the grille inside. This cleaning is more troublesome, so it is necessary to design an interception device for sewage treatment. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-3 The interception device for sewage treatment provided by the utility model includes a channel 1, both side walls of the channel 1 are fixedly connected to a limit frame 9, and an interception net 10 is detachably connected to the limit frame 9; a power mechanism and a scraper 14 are arranged inside the channel 1, the channel 1 is connected to the scraper 14 through the power mechanism, and a reset mechanism is arranged on the power mechanism, and the reset mechanism is used to drive the scraper 14 to reset.

[0025] Specifically, sewage enters the interior of the channel 1, and then the impurities in the sewage can be intercepted by the action of the intercepting net 10. When the intercepting net 10 needs to be cleaned, the scraper 14 is driven to move by the power mechanism. When the scraper 14 contacts the intercepting net 10, the surface of the intercepting net 10 can be cleaned by the action of the scraper 14. At the same time, with the cooperation of the resetting mechanism, the scraper 14 can be tightly fitted with the surface of the intercepting net 10, so that the scraper 14 can better clean the surface of the intercepting net 10, so that the intercepting net 10 does not need to be manually cleaned when it needs to be cleaned, thereby reducing the labor intensity of the workers. At the same time, the power mechanism keeps running, and the scraper 14 can be driven to clean the front of the intercepting net 10 all the time, thereby effectively preventing impurities from clogging the intercepting net 10.

[0026] The power mechanism includes a bearing seat 2, a first rotating shaft 3, a motor 4, a first synchronous wheel 5, a synchronous belt 6, a second rotating shaft 7 and a second synchronous wheel 8. The bearing seat 2 is fixedly connected to both sides of the upper end of the channel 1. The first rotating shaft 3 is rotatably connected inside the bearing seat 2. The first rotating shaft 3 is fixedly connected to the first synchronous wheel 5 on the circumferential surface. The motor 4 is fixedly connected to the right side of the bearing seat 2 on the right side, and the output end of the motor 4 is fixedly connected to the first rotating shaft 3; the second rotating shaft 7 is rotatably connected inside the channel 1, and the circumferential surface of the second rotating shaft 7 is fixedly connected to the second synchronous wheel 8. The second synchronous wheel 8 and The first synchronous wheels 5 are connected by a synchronous belt 6, and two second synchronous wheels 8, the first synchronous wheels 5 and the synchronous belt 6 are each provided and symmetrically distributed on both sides of the channel 1. A scraper 14 is rotatably connected between the two synchronous belts 6. When working, the motor 4 is turned on, and the first synchronous wheel 5 can be driven to rotate under the action of the first rotating shaft 3, and then the synchronous belt 6 can be driven to move with the cooperation of the second synchronous wheel 8. As the synchronous belt 6 moves, the scraper 14 on the synchronous belt 6 can be driven to move, so that the scraper 14 can clean the interception net 10 conveniently.

[0027] The scraper 14 has a plurality of circular holes 1401 evenly distributed on the surface of the scraper 14. When the scraper 14 is in operation, the circular holes 1401 facilitate water to flow out of the scraper 14, thereby reducing the resistance of the scraper 14 when it moves.

[0028] The reset mechanism includes a fixed block 13, a first rotating block 15, a spring 16 and a second rotating block 17. The side end surface of the synchronous belt 6 is rotatably connected to the second fixed block 13; the surface of the scraper 14 is fixedly connected to the fixed block 13, and the side end surface of the fixed block 13 is rotatably connected to the first rotating block 15. A spring 16 is fixedly connected between the first rotating block 15 and the second rotating block 17. During operation, when the scraper 14 contacts the interception net 10, the scraper 14 will be squeezed to rotate, and then the spring 16 can be stretched with the cooperation of the first rotating block 15 and the second rotating block 17. The stretched spring 16 can make the scraper 14 fit tightly to the front of the interception net 10, so that the front of the interception net 10 can be better cleaned.

[0029] The upper end of the channel 1 is fixedly connected with a first guide groove 11, the first guide groove 11 is located at the upper end of the interception net 10, and the front end surface of the first guide groove 11 is flush with the front end surface of the interception net 10, and the rear end of the first guide groove 11 is fixedly connected with a second guide groove 12; the left end of the bottom of the second guide groove 12 is higher than the right end, and the bottom of the second guide groove 12 is lower than the bottom of the first guide groove 11; during operation, by setting the first guide groove 11 and the second guide groove 12, when the scraper 14 reaches the upper end of the first guide groove 11, the impurities on the scraper 14 will fall into the first guide groove 11, and then enter the second guide groove 12 along the first guide groove 11, and finally be discharged outward from the second guide groove 12, so that the centralized cleaning of impurities can be achieved.
