[0039] Figures 1 to 9 The purifier of the present invention includes a support base 100 , a reaction kettle 200 , a stirring assembly 300 , an adsorption mechanism 400 , a drain valve group 500 , a plugging assembly 600 and a pump and electrical device 700 .

[0040] The support base 100 is used to support and install the reactor 200, the stirring assembly 300, the adsorption mechanism 400, the sealing assembly 600, and the drain valve assembly 500. Specifically, the support base 100 includes a base 110, a support frame 120 disposed perpendicular to the base 110, and a horizontal support 130 disposed perpendicular to the support frame 120. The support base 100 also includes a protective frame 140 vertically connected to the support frame 120 and surrounding the top of the tank body 210, and a bottom bracket 150 fixed to the support frame 120, surrounding the junction of the tank body 210 and the cylindrical portion 210a, and supporting the junction.

[0041] The support frame 120 includes a first connecting block 120a, a second connecting block 120b, a rod 120d, and a mounting post 120e. The rod 120d is fixed to the base 110 and connected to the mounting post 120e via the first connecting block 120a and the second connecting block 120b. The rod 120d and the mounting post 120e are perpendicular to each other.

[0042] Preferably, in this embodiment, the protective frame 140 includes a sleeve 140a fixed on the support frame 120, a connecting rod 140b with one end perpendicularly arranged to the sleeve 140a, a first frame 140c connected to the other end of the connecting rod 140b, a second frame 140d detachably connected to the first frame 140c and surrounding the tank body 210 with the first frame 140c, and a limiting ring 140e whose bottom abuts against the top of the cover plate 220 and is fixed to the first frame 140c by a screw.

[0043] The reactor 200 is used to react the liquid inside. Specifically, the reactor 200 includes a tank body 210, a cover plate 220 that closes the top of the tank body 210, and a cylindrical portion 210a with a smaller diameter than the bottom of the tank body 210. The bottom of the cylindrical portion 210a has a guide tube 210b, and the side wall of the guide tube 210b has a drainage pipe 210c connected thereto. The top of the cover plate 220 has a liquid addition port. Specifically, the top of the cover plate 220 has a target solution addition port 220a and multiple cleaning solution addition ports 220b.

[0044] The stirring assembly 300 is mounted on the horizontal support 130 and partially extends into the reactor 200 to stir the interior of the reactor 200. Specifically, the stirring assembly 300 includes a rotating rod 310 extending into and coaxially arranged with the tank body 210, stirring blades 320 evenly arranged on the side walls of the rotating rod 310, and a first driving member 330 that drives the rotating rod 310 to rotate. When the first driving member 330 is in operation, the rotating rod 310 rotates, thereby driving the stirring blades 320 to stir the reactor 200. Specifically, the first driving member 330 is a motor.

[0045] The adsorption mechanism 400 is mounted on the support frame 120 and can drive the magnetic block 440 to move closer to or away from the tank body 210 to adsorb the magnetic beads in the tank body 210. Specifically, the adsorption mechanism 400 includes a connecting frame 410 fixed to the support frame 120, a support plate 420 fixedly connected to the connecting frame 410 and having symmetrically arranged slide rails 420a at the bottom, a movable plate 430 symmetrically arranged at the bottom of the support plate 420, two magnetic blocks 440 respectively fixed to one end of the two movable plates 430 and located on both sides of the tank body 210, and a second driving member 450 fixed to the top of the connecting frame 410. The top of the two movable plates 430 has a slider 430b that slides in the slide rail 420a and a rack 430a on the side. The output end of the second driving member 450 extends from the top to the bottom of the support plate 420 and the outer wall has a gear 450a that engages with two mutually symmetrical racks 430a. During specific use, the second driving member 450 drives the gear 450a to rotate, and the gear 450a drives the two symmetrical movable plates 430 to move in opposite directions through the rack 430a, thereby driving the two symmetrical magnetic blocks 440 to move in opposite directions toward or away from the tank body 210, thereby adsorbing or releasing the magnetic beads in the tank body 210, thereby achieving mixing of the liquid in the tank body 210 or cleaning of the tank body 210.

[0046] There are multiple adsorption mechanisms 400, each arranged vertically. Reactor 200 also includes a liquid level sensor 210d, which senses the liquid level within reactor 200. The purifier controls the number of adsorption mechanisms 400 in operation based on the liquid level within reactor 200. Specifically, in this embodiment, there are two adsorption mechanisms 400.

[0047] The plugging assembly 600 is mounted on the support seat 100 and can be driven by rotation to rise and fall in the guide tube 210b to connect or block the guide tube 210b with the drainage pipe 210c. In this embodiment, the plugging assembly 600 includes a lifting ring 610, a bushing 620, a rotating sleeve 630 and a third drive motor 640. The lifting ring 610 has an inner wall that is threadedly connected to the outer wall of the guide tube 210b, and its bottom is closed, and has a plugging column 610a inserted into the guide tube 210b. The inner wall of the bushing 620 is threadedly connected to the outer wall of the lifting ring 610. The rotating sleeve 630 is keyed to the outer wall of the bushing 620, and the bottom of the rotating sleeve 630 has a shaft column. The output end of the third drive motor 640 is fixed to the shaft column via a coupling 650. When the third drive member 640 drives the rotating sleeve 630 to rotate via the coupling, the rotating sleeve 630 drives the bushing 620 to rotate. When the bushing 620 rotates, it drives the lifting ring 610 to rise and fall along the guide tube 210b, so that the blocking column 610a rises and falls within the guide tube 210b, thereby connecting or blocking the guide tube 210b with the drainage pipe 210c. Specifically, the third drive member 640 is a motor.

[0048] The drain valve group 500 is installed on the base 110 and is connected to the drain pipe 210c through a pipeline. Specifically, the drain valve group 500 includes a fixed plate 510 fixed on the base 110 and having a mounting plate 510a, a four-way pipe 520 fixed on the mounting plate 510a and the inlet end of which is connected to the drain pipe 210c through a pipeline, and a plurality of drain valves 530 connected to the outlet end of the four-way pipe 520 through a pipeline. Preferably, in this embodiment, a capacitive liquid level sensor 210d is installed on the side wall of the tank body 210 near the lower position, and the capacitive liquid level sensor 210d is electrically connected to the drain valve 530.

[0049] The pump-electric device 700 has a plurality of peristaltic pumps 710, and the discharge ends of the plurality of peristaltic pumps 710 are connected to the cleaning solution filling port 220b through pipelines in a one-to-one manner. In the present embodiment, there are four peristaltic pumps 710, which correspond to the water tank, the combined liquid tank, the cleaning liquid tank and the elution liquid tank respectively. The inlet ends of the four peristaltic pumps 710 are connected to the water tank, the combined liquid tank, the cleaning liquid tank and the elution liquid tank in a one-to-one manner through pipelines, and the outlet ends of the four peristaltic pumps 710 are connected to the cleaning solution filling port 220b in a one-to-one manner through pipelines.
