Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a mud filtering device for sewage treatment. Background Art

[0002] Sewage treatment mainly refers to the process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment has currently been widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, and catering, and it is also increasingly entering the daily lives of ordinary people. Currently, when purifying mud sewage in sewage, it is necessary to dehydrate the mud sewage before subsequent processing. When the existing mud filtering device for sewage treatment is in use, it cannot filter the mud in a hierarchical manner. The mud contains mud mixtures with various diameters. One-time filtration not only makes it difficult to completely filter out the mud, but also easily clogs the filter screen, greatly reducing the filtering effect of the filter screen. For small-particle and viscous mud, ordinary filter screens cannot effectively filter it, reducing the dehydration efficiency of the mud. Therefore, we have proposed a mud filtering device for sewage treatment. Content of the Utility Model

The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0023] Such as Figures 1-3As shown in the figure, the utility model is a mud filtration device for sewage treatment, including a support frame 1. Above the support frame 1, there is a filtration tank 2. At the lower end inside the filtration tank 2, there is a support ring 3. At the four corners above the support ring 3, there are guide rods 4. A first fixing ring 5 is sleeved on the four guide rods 4. The first fixing ring 5 is movably connected to the guide rods 4. In the middle of the first fixing ring 5, there is a first filter screen 6. Above the first fixing ring 5, there are four connecting rods 8 arranged in a matrix. The upper part of the connecting rods 8 is fixedly connected to a second fixing ring 9. In the middle of the second fixing ring 9, there is a second filter screen 10. The first fixing ring 5 can move vertically on the guide rods 4. Through the transmission of the connecting rods 8, the second fixing ring 9 also moves vertically accordingly. When the first fixing ring 5 and the second fixing ring 9 move, the second filter screen 10 and the first filter screen 6 can filter the mud respectively. The mesh of the second filter screen 10 is larger than that of the first filter screen 6. Thus, the second filter screen 10 and the first filter screen 6 can filter mixtures of different sizes in the mud respectively. In the middle of the upper part of the filtration tank 2, there is a housing 11. In the middle of the upper part of the housing 11, there is a motor 12. The rotating shaft of the motor 12 penetrates the housing 11 and is fixedly connected to a first bevel gear 13. On both sides inside the housing 11, there are support plates 14. An active rod 15 is inserted on the two support plates 14. On the active rod 15, there is a second bevel gear 16 meshing with the first bevel gear 13. At both ends of the active rod 15, there are turntables 17. The outer side of the turntable 17 is movably connected to a push rod 18. On both sides of the upper part of the second fixing ring 9, there are fixing plates 19. The lower part of the push rod 18 is movably connected to the fixing plate 19. The housing 11 is provided with a through groove below the turntable 17. The push rod 18 penetrates the through groove and is movably connected to the fixing plate 19. When the motor 12 works, the motor 12 drives the first bevel gear 13 to rotate. Driven by the first bevel gear 13, the second bevel gear 16 meshing with the first bevel gear 13 can drive the active rod 15 and the turntable 17 to rotate. When the turntable 17 rotates, through the transmission of the push rod 18, the first fixing ring 5 and the second fixing ring 9 can move vertically.

[0024] A spring 7 is sleeved between the support ring 3 and the first fixing ring 5 on the guide rod 4. The two ends of the spring 7 are respectively between the support ring 3 and the first fixing ring 5. When the first fixing ring 5 moves vertically, the spring 7 is stretched or compressed by force. Through the elastic force of the spring 7, the first fixing ring 5 can automatically reset.

[0025] A limit plate 20 is arranged above the guide rod 4. The limit plate 20 can limit the first fixing ring 5.

[0026] On the side wall of the filter tank 2 above the first fixing ring 5 and the second fixing ring 9, there are doors 21. The lower part of the door 21 is movably connected to the filter tank 2. When the door 21 is opened, the mud filtered by the second filter screen 10 and the first filter screen 6 can be discharged through the door 21.

[0027] On both sides above the door 21, there are connecting plates 22. In the middle above the connecting plates 22, there is a connecting groove 23. In the middle of the connecting groove 23 of the filter tank 2, there is a threaded rod 24. There is a nut 25 on the threaded rod 24. The nut 25 is threadedly connected to the threaded rod 24. Through the mutual cooperation between the nut 25 and the threaded rod 24, the connection between the door 21 and the filter tank 2 can be stably achieved.

[0028] In the middle below the filter tank 2, there is a liquid discharge pipe 26. There is a valve 27 on the liquid discharge pipe 26. The water after mud filtration can be discharged through the liquid discharge pipe 26, and the valve 27 can control the on-off of the liquid discharge pipe 26.

[0029] Specifically, in the present utility model, when the motor 12 is working, the motor 12 drives the first bevel gear 13 to rotate. Driven by the first bevel gear 13, the second bevel gear 16 meshing with the first bevel gear 13 can drive the movable rod 15 and the turntable 17 to rotate. When the turntable 17 rotates, through the transmission of the push rod 18, the first fixing ring 5 and the second fixing ring 9 can move in the vertical direction. When the first fixing ring 5 and the second fixing ring 9 move, the second filter screen 10 and the first filter screen 6 also move accordingly. The second filter screen 10 and the first filter screen 6 in vibration can filter mixtures of different sizes in the mud respectively. The mud filtered by the second filter screen 10 and the first filter screen 6 can be taken out from the opened door 21.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
