Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an automatic lime dosing device for sewage treatment. Background Art

[0002] In the sewage treatment process, lime, as a commonly used alkaline neutralizer, is widely used to adjust the pH value of sewage in order to purify the water quality.

[0003] Conventional lime dosing involves manually sprinkling lime into sewage treatment tanks. This method results in the dispersal of lime dust, polluting the surrounding work environment. It also often leads to uneven dosing and complex operation, impacting the effectiveness and efficiency of sewage treatment. Inventing an automatic lime dosing device for sewage treatment to address these issues has become a pressing issue for those skilled in the art. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides an automatic lime dosing device for sewage treatment, which aims to solve the problem of uneven lime dosing in the traditional lime dosing method.

[0005] The utility model is achieved in this way:

[0006] The utility model provides an automatic lime dosing device for sewage treatment, comprising a sewage pool and a dosing tube arranged on the sewage pool, wherein tooth grooves are installed on both sides of the sewage pool;

[0007] A plurality of partitions are installed on the inner wall of the delivery cylinder, a mounting frame is installed at one end of the delivery cylinder, a motor is installed at one end of the mounting frame, a storage box is installed above the delivery cylinder, a plurality of discharge troughs connected to the interior of the delivery cylinder are installed at the lower end of the storage box, a drive shaft is installed on the inner wall of the delivery cylinder, gears are installed at both ends of the drive shaft, a plurality of spiral conveying blades are installed on the outer wall of the drive shaft, and a plurality of discharge pipes are installed on the lower inner wall of the delivery cylinder.

[0008] Preferably, the plurality of partitions divide the delivery cylinder into a plurality of separate spaces, each of the spiral conveying blades is installed in a cavity between the delivery cylinder and the partition, and the inner wall of the partition is rotatably connected to the outer wall of the drive shaft.

[0009] Preferably, the position where the discharge chute is connected to the delivery barrel and the position of the discharge pipe are close to both ends of the spiral conveying blade.

[0010] Preferably, both ends of the driving shaft are rotatably connected to the inner wall of the delivery barrel, one end of the driving shaft is fixedly connected to the output end of the motor, and the gear and the tooth groove are meshingly connected.

[0011] By adopting the above technical solution, lime is put into the storage box and enters various areas of the feeding cylinder through the feeding chute. The motor drives the entire feeding assembly to move on the sewage pool. At the same time, the spiral conveying blades on the outside of the driving shaft move one end of the cavity to the side of the lower feeding pipe. Then, under the action of gravity, the lime is relatively evenly fed into the sewage pool to ensure that all areas in the sewage pool can be covered with lime, thereby ensuring the effect of sewage treatment.

[0012] Preferably, a tooth plate is installed on the inner wall of one side of the sewage pool, a limiting groove is opened on the outer wall of the discharge pipe, a central sleeve is installed on the outer wall of the discharge pipe, and a limiting ring rotatably connected to the limiting groove is installed on the inner wall of the central sleeve.

[0013] Preferably, a communicating delivery frame is installed at one end of the centralizing sleeve, and a plurality of discharge holes are provided on the surfaces of the centralizing sleeve and the delivery frame.

[0014] Preferably, a gear ring meshing with a gear plate is installed on the outer wall of one of the discharge pipes, and a toothed belt wheel is installed on the outer wall of the discharge pipe, and a transmission toothed belt is connected to the toothed belt wheel for transmission.

[0015] By adopting the above technical solution, during the process of lime feeding, the feeding component moves, and the multiple centralized sleeves at the lower end of the discharge pipe rotate. Under the action of centrifugal force, the internal lime powder is discharged to the surrounding through the discharge hole, further improving the uniformity of lime feeding and ensuring the effect of sewage treatment.

[0016] The beneficial effects of the utility model are:

[0017] The spiral blades on the outside of the driving shaft and the gears at both ends realize the mobile delivery of lime, ensuring that the lime can be evenly and continuously delivered through the discharge pipe during the movement, ensuring that all areas in the sewage pool can be covered with lime, thereby improving the effect of subsequent sewage treatment. The delivery frame arranged at the lower end of the discharge pipe rotates during the delivery process, and the centrifugal force generated by the rotation causes the lime to be delivered to the surrounding area through the discharge hole. At the same time, the delivery frame rotates to stir the surrounding water body, so that the lime delivered into the water body can be evenly distributed around the delivery point, thereby improving the uniformity of lime delivery and further ensuring the effect of sewage treatment.

[0030] It should be noted that: when treating the sewage in the sewage pool 1, the lime is put into the storage box 8 for storage, and some of the lime enters the various areas of the delivery barrel 4 through the discharge chute 9 to stay. The motor 7 is started to rotate the drive shaft 10, and the gears 12 and the tooth grooves 2 at both ends of the shaft are engaged, forcing the entire feeding assembly to move. At the same time, the spiral conveying blades 11 rotate to move the lime in each space in the delivery barrel 4 from one end to one end of the lower feeding pipe 13.
