1. A dosing equipment (400), comprising:
a container (211) which is adapted to hold reagent and includes a container opening;
a dosing apparatus (100), which is at least partially provided within the container (211) and is connecting with an interior and an exterior of the container (211) to convey the reagent from the interior of the container (211) to the exterior of the container (211); and
a connector structure (220) which is adapted to connect the container opening and the dosing apparatus (100);
wherein the connector structure (220) includes a connector (221); and the connector structure (220) penetrates the container along an axial direction of the container opening, a support member (222) and a bearing member (223) sequentially socketed within the connector (221); wherein the connector (221) is socketed on an outer periphery of the container opening; wherein a gap is provided between the connector (221) and the support member (222) to receive a sidewall (211a) of the container opening; wherein the bearing member (223) is provided outside the dosing apparatus (100); wherein a first sealing ring (224) and a second sealing ring (225) are provided between the support member (222) and the bearing member (223) and between the support member (222) and the sidewall (211a) of the container opening, respectively, so as to seal-connect the connector structure (220), the dosing apparatus (100), and the container opening, respectively;
wherein the dosing apparatus (100) comprises:
a first channel (111), wherein the first channel (111) has a first channel first opening (111a) connecting with the container (211) to allow the reagent when held inside the container (211) to enter the first channel (111), and a first channel second opening (111b) which is in connection with outside of the first channel (111) to allow the reagent to leave the first channel (111); and
at least one first spiral rod (112) provided within the first channel (111), wherein the least one first spiral rod (112) is configured to be driven to rotate in a first direction, so as to deliver the reagent from the first channel (111) to the first channel second opening (111b), and wherein a mass flow rate of the reagent leaving through the first channel second opening (111b) is controlled by adjusting a rotational speed of the at least one first spiral rod (112).
