Description

Technical Field

[0001] The utility model relates to the technical field of powder feeding, in particular to a powder feeding mechanism. Background Art

[0002] When treating sewage, it is generally necessary to add disinfectant powder and flocculation powder to the water. At present, the method of adding these powders is to directly add them after metering. This method of adding makes it difficult for the powder to dissolve in water, and some of the powder is easy to agglomerate together after adding, thus forming lumps, which results in the actual amount of the treatment agent being less than the rated amount, thus affecting the sewage treatment effect. Utility Model Content

[0003] The utility model provides a powder feeding mechanism to solve the above-mentioned shortcomings of the prior art, can avoid the agglomeration of powder when feeding, thereby improving the sewage treatment effect, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A powder feeding mechanism includes a feeding hopper, the lower end of the feeding hopper is connected to a feeding pipe, the outer periphery of the feeding pipe is provided with an end ring, a plurality of guide pins are provided on the end ring, a movable ring is provided at the lower end of the guide pin, a feeding pipe is provided on the movable ring, the feeding pipe is sleeved on the feeding pipe, the lower end of the feeding pipe is provided with an end cover, a plurality of feeding holes are provided on the end cover, a connecting block is provided at the upper end of the feeding pipe, a cover plate is installed on the upper end of the feeding hopper, a feed pipe is connected to the cover plate, a shaking mechanism is installed on the cover plate, and the lower end of the shaking mechanism is connected to the connecting block. The feeding pipe can be reciprocated up and down by the driving energy of the shaking mechanism, and the medicinal powder is dispersed downward through the feeding hole during the shaking. This dispersed feeding can promote the rapid dissolution of the medicinal powder in water without forming lumps, thereby improving the effect of sewage treatment. The feeding pipe is sleeved on the feeding pipe to prevent the medicinal powder from being scattered.

[0006] Furthermore, the shaking mechanism includes four support rods installed on the cover plate, an upper plate is installed on the upper end of the support rods, a motor is installed on the upper plate, a worm is connected to the output shaft of the motor, a worm wheel is meshed on the worm, rotating seats are respectively provided at both ends of the worm wheel, the rotating seats are installed on the upper plate, both ends of the worm wheel are connected to the rotating plate through a rotating shaft, and a rocker is provided at the other end of the rotating plate, one pair of support rods is provided with a movable block, a concave plate is installed on the movable block, transverse holes are opened on both sides of the concave plate, the rocker passes through the transverse holes, a movable vertical plate is installed on the concave plate, and the lower end of the movable vertical plate is installed on the connecting block, the shaking mechanism is to make the concave plate perform reciprocating lifting and lowering motion through the rotation of the rocker, and the lifting and lowering motion of the concave plate can make the powder in the feeding tube pass through the hole to discharge downward in a dispersed manner, and when the lower feeding tube moves upward, the powder can also move downward through the feeding eye due to the extrusion of the powder.

[0007] Furthermore, a sleeve plate is provided at one end of the concave plate, and another pair of support rods are passed through the sleeve plate. The arrangement of the sleeve plate further improves the stability of the shaking.

[0008] Furthermore, the output shaft of the motor is connected to a stirring rod through a coupling, the stirring rod is located in the feeding hopper, and a stirring blade is arranged on the stirring rod. The stirring blade can stir the powder in the feeding hopper to avoid the problem of powder agglomeration and inconvenience in feeding as the ambient humidity increases.
