Therefore, an arch bridge is extremely easy to generate in the hopper during the discharging process of the hopper. Especially, when the cone angle of the hopper is 60 degrees, the arch bridge effect is more obvious. The generation of the arch bridge causes that the activated carbon can not uniformly and smoothly flow out of the hopper, so that the adding amount is difficult to accurately control.

Referring to fig. 1, 2 and 3, the present application provides a dosing machine comprising a hopper 110 with a conical structure, where it should be noted that the conical angle of the hopper 110 is 60 degrees. A distribution cylinder 120 having a cylindrical structure is fixed to the bottom of the hopper 110, and the distribution cylinder 120 communicates with the inside of the hopper 110. The distribution barrel 120 can distribute the activated carbon to a plurality of material conveying mechanisms in time so as to facilitate the addition of the activated carbon to a plurality of addition points.

The dosing machine further comprises an arch breaking mechanism 130. Specifically, the arch breaking mechanism 130 includes a first driving motor 131, and the first driving motor 131 is fixed on the bottom end surface outside the dispensing cylinder 120 and is electrically connected to an external power source. An output shaft of the first driving motor 131 is fixedly connected with the rotating shaft 132 to drive the rotating shaft 132 to rotate. The shaft 132 is disposed through the dispensing cylinder 120 and the hopper 110. A first fixed disk 133 is sleeved on the rotating shaft 132, the first fixed disk 133 is located in the hopper 110, and a first scraper 134 extending towards the inner wall of the hopper 110 is fixed on the first fixed disk 133. When the hopper 110 generates an arch bridge, the first scraper 134 can break the arch bridge, so that the activated carbon can uniformly and smoothly flow out of the hopper 110, and the adding amount of the activated carbon is easy to control accurately. A flow rate regulating valve 140 is provided between the bottom of the hopper 110 and the top of the dispensing cartridge 120. Here, it should be noted that the flow rate regulating valve 140 may be an electric flow rate regulating valve or a manual flow rate regulating valve, and the flow rate regulating valve 140 can regulate the outflow rate of the activated carbon in the hopper 110. When the height of the active carbon piled up in the hopper is different, the influence of the piled density on the adding amount can be reduced by adjusting the outflow speed, and the accuracy of the adding amount is further improved. On the whole, the adding amount of the active carbon can be accurately controlled, so that the adding amount of the active carbon is saved, and secondary pollution is avoided.

A second fixed disk 135 is further sleeved on the rotating shaft 132, the second fixed disk 135 is located in the distribution cylinder 120, a second scraper 136 extending toward the inner wall of the hopper 110 is fixed on the second fixed disk 135, and the bottom of the second scraper 136 abuts against the bottom end face in the distribution cylinder 120. The activated carbon dropped into the distribution drum 120 is distributed to the plurality of material conveying mechanisms 150 by the urging of the second scraper 136.

Wherein, the first scraper 134 is an elastic steel sheet. When no arch bridge is formed in the hopper 110, the first scraper 134 is in a rolling state, so that the occupancy rate of the space is reduced, and the service life of the first scraper 134 is prolonged.

Further, the first fixed disks 133 are plural, and the plural first fixed disks 133 are uniformly distributed from top to bottom along the axial direction of the rotating shaft 132. In this way, arch bridges can be broken when formed at different heights within the hopper 110. The diameters of the first fixed disks 133 are sequentially decreased, thereby effectively saving materials. The first scrapers 134 are also plural, and the first scrapers 134 correspond to the first fixed disks 133 one to one. The lengths of the plurality of first scrapers 134 are sequentially decreased, effectively saving materials. The number of the second fixed disk 135 is one, the number of the second scrapers 136 is two, and the two second scrapers 136 are oppositely arranged on two opposite sides of the second fixed disk 135.

In an embodiment of the present invention, the first scraper 134 is connected to the first fixed disk 133 in a screw manner, so that the first scraper 134 can be detached, replaced, installed and used. The second scraper 136 is connected with the second fixed disk 135 in a welding manner, and the connecting position has high mechanical strength and high stability.

In an embodiment of the present invention, the quantitative feeding machine further includes a material conveying mechanism 150, the material conveying mechanism 150 includes a material conveying cylinder 151 having a cylindrical structure, the material conveying cylinder 151 is located below the distribution cylinder 120, and the axes of the material conveying cylinder 151 and the distribution cylinder 120 are perpendicular to each other.

The side wall of the delivery cylinder 151 near one end of the second driving motor 152 is provided with a material receiving opening 1511 with an upward opening, and the end far away from the second driving motor 152 is provided with a material output opening 1512 with a downward opening. Correspondingly, the bottom of the distribution barrel 120 is provided with a material distribution hole 121, and the material distribution hole 121 is opposite to the material receiving port 1511. The activated carbon in the distribution cylinder 120 flows out from the material distribution hole 121 under the pushing of the second scraper 136, and then enters the material delivery cylinder 151 from the material receiving port 1511. The second driving motor 152 drives the pushing screw to push the activated carbon in the feeding cylinder 151 to flow out from the material output port 1512. A guide hose is fixed to the material outlet 1512 to guide the powdered activated carbon to the point of addition.

the first driving motor 131 drives the rotating shaft 132 to rotate so as to drive the first fixed disk 133, the second fixed disk 135, the first scraper 134 and the second scraper 136 to rotate. When the powdered activated carbon normally falls, the first scraper 134 is in a rolled state; when the bridge is formed in the hopper 110, the first scraper 134 is gradually spread by resistance against the movement direction thereof, and breaks the arch bridge with the rotation of the first fixed disk 133, so that the powdered activated carbon in the hopper 110 can be continuously and uniformly discharged. Meanwhile, the second fixed disc 135 cooperates with the second scraper 136 to uniformly distribute the activated carbon in the distribution cylinder 120 to the material delivery cylinders 151 of the plurality of material delivery mechanisms 150, each material delivery cylinder 151 is provided with a material receiving port 1511, and the powdered activated carbon flowing out from one of the material distribution holes 121 enters one of the material delivery cylinders 151 through one of the material receiving ports 1511 and can fill up the gaps of the helical blades of the pushing screw.
