Description

A stirring device for a sewage treatment tank

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment pool stirring device.

Background Art

The sludge in the sewage treatment tank will gradually settle at the bottom of the tank over time. If it is not stirred, the sludge will gradually harden and form a sludge layer, which will affect the growth of microorganisms and the supply of oxygen at the bottom. If the sludge cannot be effectively dispersed and mixed, it will lead to reduced treatment efficiency and even problems such as odor. Therefore, the sludge can be effectively dispersed in the water by stirring, making it easier for microorganisms to decompose, thereby improving treatment efficiency and water quality. In the prior art, the common stirring method is as follows: multiple horizontal plates are set up above the sewage treatment tank, and multiple agitators are distributed on the horizontal plates. Each agitator is driven by a motor to stir the sewage in the tank. In this method, the position of the agitator is fixed. The closer to the agitator, the better the dispersion effect of the sludge in the sewage, and the farther away from the agitator, the worse the sludge dispersion effect.

Utility Model Content

In order to solve the deficiencies of the prior art, the utility model provides a sewage treatment pool stirring device, the position of the stirrer can be moved, and stirring can be achieved while moving.

In order to achieve the purpose of this utility model, the following scheme is proposed:

A sewage treatment pool stirring device comprises a reciprocating mechanism and a stirring mechanism.

The reciprocating mechanism includes two moving plates, two guide rods, a horizontal plate and a power assembly. The guide rods and the horizontal plate are respectively arranged above the sewage treatment tank through a first bracket and a second bracket. The two ends of the moving plate are respectively slidably matched with the guide rods. The power assembly includes a motor, a first regulating rod and two second regulating rods. The output shaft at the bottom of the motor passes through the horizontal plate and is connected to the center of the first regulating rod. The end of the first regulating rod is rotatably connected to one end of the second regulating rod. The bottom of the other end of the second regulating rod is rotatably connected to the moving plate. The two second regulating rods are symmetrical about the center of the motor. The power assembly is used to make the moving plate reciprocate.

The stirring mechanism includes four stirring pieces and two racks. The racks are located above the corresponding guide rods. The ends of the racks are connected to the first bracket. The stirring piece includes an agitator and a gear. The gear is rotated on the movable plate through a column. The bottom of the column passes through the movable plate and is connected to the agitator. The gear meshes with the corresponding rack.

Furthermore, the horizontal plate is provided with two slide grooves, and a roller is provided at the top of the other end of the second regulating rod. The roller slides in the corresponding slide groove, and a convex plate larger than itself is provided on the top of the roller, and the bottom surface of the convex plate is close to the top surface of the horizontal plate.

Furthermore, a stirrer is provided at the center bottom of the first regulating rod.

Furthermore, each rack includes a smooth rod and saw teeth arranged at both ends, and the gear meshes with the corresponding saw teeth.

Furthermore, a sliding block is provided at the end of the movable plate, the sliding block is provided with a through hole, and the guide rod passes through the through hole.

The beneficial effect of the utility model is that compared with the prior art in which one motor drives one agitator, the utility model only needs one motor. When the motor drives the first regulating rod to reciprocate the movable plate, all gears are driven to rotate, thereby causing all agitators to rotate. Compared with the agitator with a fixed position in the prior art, the position of the agitator in the utility model is not fixed, but moves with the movable plate. The agitator moves and stirs at the same time. This stirring method can improve the dispersion and mixing effect of sludge.

DETAILED DESCRIPTION

As shown in FIG1 , this embodiment provides a sewage treatment tank stirring device, including a reciprocating mechanism 1 and a stirring mechanism.

Specifically, as shown in FIG1 , the reciprocating mechanism 1 includes two moving plates 11, two guide rods 12, a horizontal plate 13 and a power assembly, the two ends of the guide rods 12 are arranged above the sewage treatment tank 4 through the first bracket 121, the two ends of the horizontal plate 13 are arranged above the sewage treatment tank 4 through the second bracket 131, the two guide rods 12 are symmetrical about the horizontal plate 13, and the three are parallel. As shown in FIG4 , a slider 111 is provided at the end of the moving plate 11, the slider 111 is provided with a through hole 112, the guide rod 12 is passed through the through hole 112, and the two ends of the moving plate 11 are respectively slidably matched with the guide rod 12. As shown in FIG2 , the power assembly includes a motor 141, a first regulating rod 142 and two second regulating rods 143, the output shaft at the bottom of the motor 141 passes through the horizontal plate 13 and is connected to the center of the first regulating rod 142, the end of the first regulating rod 142 is rotatably connected to one end of the second regulating rod 143, the bottom of the other end of the second regulating rod 143 is rotatably connected to the moving plate 11, and the two second regulating rods 143 are symmetrical about the output shaft center of the motor 141.

The power assembly is used to make the moving plate 11 reciprocate, and the specific method is: in the perspective of Figure 2, the motor 141 drives the first regulating rod 142 clockwise, and the first regulating rod 142 pulls the second regulating rod 143. Because the moving plate 11 is slidably matched with the guide rod 12, when the second regulating rod 143 is pulled, the two moving plates 11 will gather together. Conversely, the motor 141 drives the first regulating rod 142 counterclockwise, and the first regulating rod 142 pushes the second regulating rod 143, and the two moving plates 11 will move away from each other.

Specifically, as shown in Figure 1, the stirring mechanism includes four stirring members and two racks 21. The racks 21 are located above the corresponding guide rods 12. The ends of the racks 21 are connected to the first bracket 121. Each rack 21 includes a smooth rod 211 and saw teeth 212 arranged at both ends of the smooth rod 211. The stirring member includes an agitator 22 and a gear 23. The gear 23 is rotated on the movable plate 11 through a column. The bottom of the column passes through the movable plate 11 and is connected to the agitator 22. The gear 23 engages with the corresponding saw teeth 212.

The stirring method is as follows: because the gear 23 meshes with the corresponding sawtooth 212, when the power assembly causes the moving plate 11 to reciprocate, the gear 23 is caused to rotate, thereby causing all the stirrers 22 to rotate. In this embodiment, the position of the stirrer 2 is not fixed, but moves with the moving plate 11, and the stirrer 2 stirs while moving. Compared with the agitator 2 with a fixed position in the prior art, the stirring method of this embodiment can improve the dispersion and mixing effect of the sludge.

More specifically, in order to further improve the stirring rate and mixing effect, it is possible to consider setting an agitator 22 at the center bottom of the first regulating rod 142. When the motor 141 drives the first regulating rod 142, it can naturally drive the agitator 22 below the first regulating rod 142. It is also possible to consider adding agitators at other positions of the moving plate 11. For the added agitators, the gears 23 thereof mesh with the gears 23 at the corresponding positions of the original four agitators.

More specifically, in order to improve the stability of the movable plate 11 during the reciprocating movement, as shown in Figures 2 and 3, the horizontal plate 13 is provided with two slide grooves 132, and the long axis of the slide groove 132 is consistent with the long axis direction of the horizontal plate 13. A roller is provided on the top of the connection between the second regulating rod 143 and the movable plate 11. The roller slides in the corresponding slide groove 132. A convex plate 144 larger than the roller is provided on the top of the roller. The bottom surface of the convex plate 144 is close to the top surface of the horizontal plate 13. The convex plate 144 plays a load-bearing role, bearing the gravity of the middle section of the movable plate 11 to prevent the middle section of the movable plate 11 from bending downward, deforming or breaking.

The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
