Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, and more specifically, to a chemical dosing device for sewage treatment. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it.

[0003] After retrieval, a sewage treatment chemical dosing device is disclosed in a Chinese patent with the publication number CN220723618U, which includes a base. On one side of the top of the base, a support block is installed. A mixing barrel is arranged on the top of the base. A sliding fixing mechanism for the mixing barrel is arranged on the top of the base. A stirring rod is arranged inside the mixing barrel. A brush is installed on the surface of the bottom end of the stirring rod and is connected to the bottom end of the mixing barrel. A first pulley is fixedly installed at the top end of the stirring rod. A motor is installed on the top of the support block in a bridging manner. A second pulley is fixedly installed on the output shaft of the motor. A belt is connected between the second pulley and the first pulley; through the cooperation between the mixing barrel, the sliding fixing mechanism and the base, the mixing barrel is fixed on the base. Thus, when the mixing barrel is performing the mixing operation, the centrifugal force generated by the rotation of the stirring rod will not cause shaking or tipping over under the influence of the gravity of the base, thereby improving the stability of the liquid medicine mixing.

[0004] After research by the inventor, it is found that although the above technology sets a sliding fixing mechanism on the base to ensure the stability of the mixing barrel during mixing and facilitate the disassembly of the mixing barrel, in actual use, it is necessary for personnel to disassemble the mixed mixing barrel, then transfer it, and finally pour the internal liquid medicine into the sewage tank. The use is rather troublesome. At the same time, when personnel directly pour the liquid medicine into the sewage tank without dispersing it, it greatly affects the use effect of the liquid medicine. Therefore, the utility model proposes a chemical dosing device for sewage treatment. Summary of the Utility Model

[0028] The present invention provides a technical solution: as Figures 1 - 3As shown in the figure, in this embodiment, a chemical dosing device for sewage treatment includes a base 1 and two sets of slide rails 10. A mixing tank 3 is fixedly arranged at the upper end of the base 1. A delivery pump 5 is fixed on the base 1 on the right side of the mixing tank 3. The input end of the delivery pump 5 is connected to the inside of the mixing tank 3 through a connecting pipe. The two sets of slide rails 10 are arranged on one side of the base 1. Sliding seats 15 are slidably connected to both sets of slide rails 10. A clamping block 7 is fixed to the right side of the base 1 by bolts. A fixing rod 8 is welded and fixed to the side of the clamping block 7. The other end of the fixing rod 8 is fixedly connected to the side of a sliding seat 15 close to the base 1. A U-shaped frame 11 is fixedly arranged at the upper ends of the two sliding seats 15. A conduit 18 is slidably connected inside the U-shaped frame 11. The output end of the delivery pump 5 is connected to the conduit 18 through a hose 6. Four U-shaped tubes 17 are fixedly arranged at equal intervals on the side of the conduit 18. A liquid storage cylinder 13 is fixed to the bottom of the U-shaped tube 17. The liquid storage cylinder 13 is located between the two sets of slide rails 10.

[0029] As Figure 1 and Figure 3 shown, a handle 2 is welded and fixed to the upper end of the base 1. The handle 2 is located in front of the mixing tank 3, and a controller 4 is fixed to the handle 2 through a bracket. The controller 4 is electrically connected to the delivery pump 5 through a wire. Through the handle 2, it is convenient for personnel to push the base 1. The controller 4 is electrically connected to other electrical equipment through a wire. Through the controller 4, it is convenient for personnel to control the equipment.

[0030] As Figure 2 and Figure 3 shown, pulleys 16 are installed at the corners of the bottom of the base 1. A battery box is arranged at the rear side of the upper end of the base 1. A storage battery is placed inside the battery box. The upper end of the battery box is hinged with a box cover. Through the pulleys 16, it is convenient to move the base 1. Thus, through the clamping block 7 and the fixing rod 8, the U-shaped frame 11 can be driven to move along the slide rails 10, so as to achieve the purpose of uniform chemical dosing. Through the storage battery, it is convenient to supply power to the equipment. Through the box cover, the internal storage battery can be protected.

[0031] As Figure 1 and Figure 2 shown, a lifting motor 12 is fixed to the upper end of the U-shaped frame 11. A threaded rod 14 is fixed to the lower output shaft of the lifting motor 12. The threaded rod 14 is located in front of the conduit 18. An L-shaped guide rod 21 is fixed to the U-shaped frame 11 at the rear side of the conduit 18. The bottom of the threaded rod 14 is connected to the guide rod 21 through a bearing. A connecting seat 20 is sleeved on the side of the guide rod 21. The connecting seat 20 is sleeved and fixed to the side of the conduit 18. A threaded seat 19 is fixed to the front side of the connecting seat 20. The threaded seat 19 is threadedly sleeved on the threaded rod 14. Through the lifting motor 12, the threaded rod 14 can be driven to rotate. The rotation of the threaded rod 14 will drive the connecting seat 20 to move along the guide rod 21, thereby driving the conduit 18 to move, and thus changing the height of the liquid storage cylinder 13.

[0032] AsFigure 1 and Figure 2 As shown in Figure 2 , guide grooves 9 are provided on both the left and right sides inside the U-shaped frame 11. Guide blocks are fixed on both the left and right sides of the conduit 18, and the guide blocks are slidably connected to the inside of the guide grooves 9. Through the cooperation of the guide blocks and the guide grooves 9, the stability of the conduit 18 can be ensured when the conduit 18 moves.

[0033] As Figure 1 shown in Figure 1 , a plurality of groups of liquid outlet holes are provided annularly and equidistantly on the side of the liquid storage cylinder 13, which is convenient for discharging the mixed liquid medicine and then adding it into the sewage tank.

[0034] The utility model provides a medicine adding device for sewage treatment, and the specific working principle is as follows: During normal use, there is an adding pipe at the top of the mixing tank 3, and personnel can add the liquid medicine to be mixed into the mixing tank 3. The mixing tank 3 is used for mixing. After mixing, the conveying pump 5 is operated, and at the same time, the base 1 is pushed through the handle 2 to move. The base 1 drives the U-shaped frame 11 to move on the slide rail 10 through the clamping block 7 and the fixing rod 8. At the same time, the conveying pump 5 conveys the mixed liquid medicine into the conduit 18 and then into the liquid storage cylinder 13, and then discharges it into the sewage tank through the liquid outlet holes on the side of the liquid storage cylinder 13. Moreover, according to the depth of the sewage in the sewage tank, the lifting motor 12 can be operated to adjust the height of the conduit 18, so as to adjust the height of the liquid storage cylinder 13. It is flexible to use. As the personnel push the base 1, the liquid storage cylinder 13 moves in the sewage tank, so that the mixed liquid medicine can be dispersed into the sewage tank, avoiding adding the liquid medicine at a specified position and affecting the sewage treatment effect. The operation is convenient, and there is no need to disassemble and assemble the mixing tank 3.

[0035] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
