Technical Field

The invention relates to the technical field of sewage treatment, and in particular to a carbon source adding device for an anaerobic tank of sewage treatment equipment.

Background technique

In sewage treatment, carbon source is the energy source necessary for the growth and reproduction of microorganisms. The amount of carbon source added needs to be determined according to the content and type of organic matter in the sewage to meet the needs of microorganisms. In the sewage treatment process, multiple automatic adding devices are needed to add carbon source to the anaerobic tank. The specific adding method is as follows: the automatic adding device includes a carbon source box and a lifting pump. The carbon source box is arranged outside the anaerobic tank and contains a carbon source. The suction pipe at one end of the lifting pump is arranged in the carbon source box, and the outlet pipe at the other end is arranged above the anaerobic tank. The lifting pump is used to transport the carbon source in the carbon source box to the anaerobic tank. The problem with this adding method is that because the position of the outlet pipe is fixed, during the adding process, the closer the distance to the outlet pipe, the greater the carbon source concentration in the area, resulting in a very uneven distribution of carbon source in the anaerobic tank, and there may be local excess or deficiency, which affects the final sewage treatment efficiency.

Detailed ways

As shown in FIG. 1 , this embodiment provides an anaerobic tank carbon source adding device, including four automatic adding devices, a reciprocating mechanism 1 and a stirring mechanism.

Specifically, the reciprocating mechanism 1 includes two moving plates 11, two guide rods 12, a horizontal plate 13 and a power assembly. The guide rods 12 are arranged above the anaerobic tank 4 through a first bracket 121. The horizontal plate 13 is arranged above the anaerobic tank 4 through a second bracket 131. The horizontal plate 13 is located between the two guide rods 12, and the three are parallel. The two ends of the moving plate 11 are respectively slidably matched with the guide rods 12. The moving plate 11 is located lower than the horizontal plate 13. The power assembly is arranged on the horizontal plate 13, and the power assembly is used to make the moving plate 11 reciprocate.

There are many ways to implement the power assembly. For example, a connection block is set on the top of the moving plate 11, and the screw thread runs through the connection block. When the motor drives the screw forward or reverse, the moving plate 11 can be reciprocated. The specific structure of the power assembly in this embodiment is as follows:

As shown in Figures 1 and 2, 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 movable plate 11. The two second regulating rods 143 are symmetrical about the center of the motor 141. The horizontal plate 13 is provided with two slide grooves 132 passing through it. The top of the other end of the second regulating rod 143 is provided with a roller, and the roller slides in the corresponding slide groove 132.

In the perspective of FIG2, when the motor 141 drives the first regulating rod 142 clockwise, the first regulating rod 142 will pull the second regulating rod 143. Because the other end of the second regulating rod 143 is limited by the slide slot 132, and the moving plate 11 is limited by the guide rod 12, when the first regulating rod 142 pulls the second regulating rod 143, the two moving plates 11 will gather toward the direction of the motor 141; conversely, when the motor 141 drives the first regulating rod 142 counterclockwise, the distance between the two moving plates 11 will increase. In order to further improve the stability of the moving plate 11 during movement, as shown in FIG2 and FIG4, a convex plate 144 is provided on the top of the roller. The size of the convex plate 144 is larger than that 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 to prevent the middle section of the moving plate 11 from deforming or collapsing due to gravity.

The liquid outlet pipe 31 of the automatic adding device is configured as a hose, and the mouth of the liquid outlet pipe 31 is installed on the movable plate 11. During the reciprocating movement of the movable plate 11, the liquid outlet pipe 31 simultaneously releases the carbon source into the anaerobic tank 4. Compared with placing the carbon source at a fixed point, the adding method of this embodiment can effectively improve the mixing degree of the carbon source.

In order to further improve the mixing degree of the carbon source and the sewage, a stirring mechanism is provided on the movable plate 11 in this embodiment. As shown in Figures 1 and 3, the stirring mechanism includes eight 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 stirring member includes a stirring rod 22 and a gear 23. The gear 23 is rotatably arranged on the movable plate 11 through a column 231. The bottom of the column 231 penetrates the movable plate 11 and is connected to the stirring rod 22. Four stirring members are distributed on each movable plate 11. The stirring member located on the outermost side has its gear 23 meshed with the corresponding rack 21. All gears 23 located on the same movable plate 11 and on one side of the horizontal plate 13 are meshed in sequence. In order to prevent the gear 23 from interfering with the horizontal plate 13 during operation, the bottom surface of the gear 23 is higher than the top surface of the horizontal plate 13.

Because the gear 23 of the outermost stirring element is meshed with the rack 21, when the movable plate 11 moves back and forth, the gear 23 of the outermost stirring element will rotate; because all the gears 23 located on the same movable plate 11 and on one side of the horizontal plate 13 are meshed in sequence, the gear 23 of the outermost stirring element will cause all the other gears 23 to rotate, that is, when the movable plate 11 moves back and forth, the liquid outlet pipe 31 feeds the material, and at the same time, the eight stirring elements stir the sewage, which can greatly improve the mixing degree of the carbon source and the sewage.

In order to reasonably set the position of the stirring element and prevent the stirring element from being distributed too densely, gears 23 can be added between the two stirring elements according to actual conditions. These added gears 23 are still rotatably arranged on the movable plate 11 through the columns 231. The difference is that no stirring rods 22 are arranged under these added gears 23.

The specific installation method of the liquid outlet pipe 31 is as follows:

The first solution: As shown in Figures 5 to 7, the outlet of the liquid outlet pipe 31 is connected to a hard pipe 33 through a right-angle pipe 32. The material of the hard pipe 33 is PPR, PE, copper or stainless steel, etc. A ring plate 34 is provided at the connection between the hard pipe 33 and the right-angle pipe 32. A mounting plate 51 is provided on the outer wall of the movable plate 11. The mounting plate 51 is provided with a mounting groove 511. The hard pipe 33 matches the mounting groove 511, and the bottom surface of the ring plate 34 is close to the top surface of the mounting plate 51. During installation, the hard pipe 33 can be inserted into the mounting groove 511. The hard pipe 33 in this solution is not completely fixed, and the hard pipe 33 may fall off during the reciprocating movement of the movable plate 11.

The second solution: Based on the first solution, the annular plate 34 is fixed by a positioning member. As shown in Figures 5 to 8, the positioning member includes a positioning plate 52, one end of which is provided with an arc groove 521, the arc groove 521 matches the right-angle tube 32, the bottom surface of the positioning plate 52 is close to the top surface of the annular plate 34, the top surface of the other end of the positioning plate 52 is provided with a stopper 56, the end of the stopper 56 is chamfered, the bottom surface of the other end of the positioning plate 52 is provided with a T-shaped plate 571, the bottom surface of the horizontal section of the T-shaped plate 571 is close to the top surface of the mounting plate 51, the mounting plate 51 is provided with a through groove 512 running through itself, the vertical section of the T-shaped plate 571 is slidably matched with the through groove 512, the bottom of the movable plate 11 is provided with a vertical plate 111, and the T-shaped plate 571 and the vertical plate 111 are connected by a spring 55. In the perspective of FIG6 , when the staff pushes the stopper 56 to the right, the positioning plate 52 can be moved to the right, so that the arc groove 521 is separated from the right-angle tube 32. When the staff releases the stopper 56, the positioning plate 52 fixes the right-angle tube 32 again under the action of the spring 55. In this solution, after the staff pushes the positioning plate 52 away, the positioning plate 52 cannot be kept in a fixed state for a long time. Once the staff releases the positioning plate 52, the positioning plate 52 will be reset.

The third solution: Based on the second solution, as shown in Figures 5, 6 and 8, the positioning member also includes a handle 53 and a toggle block 54. The middle section of the positioning plate 52 is provided with a straight slot 522 that runs through it. A rotating rod 513 is provided at the top of the mounting plate 51. The rotating rod 513 slides in the straight slot 522. The handle 53 is provided at the top of the rotating rod 513. The handle 53 points to the direction of the mounting groove 511. One end of the toggle block 54 is fixedly sleeved on the rotating rod 513. The long axis direction of the toggle block 54 is perpendicular to the handle 53. The other end of the toggle block 54 is chamfered. The toggle block 54 is used to push the stopper 56. In the perspective of Figure 5, the staff rotates the handle 53 counterclockwise by 90°, and the toggle block 54 gradually pushes the stopper 56 toward the moving plate 11. When the toggle block 54 is perpendicular to the stopper 56, the arc groove 521 is completely separated from the right-angle tube 32. After the positioning plate 52 is pushed open, this solution can keep the positioning plate 52 in a fixed state for a long time.

It should be understood by those skilled in the art that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
