[0036] See also Figures 1 to 7 In an embodiment of the present invention, a fully automatic silicon material acid-base integrated cleaning machine comprises:

[0037] A loader 1 is used to load and transport the cleaning frame storing silicon materials. A transport rack 11 is provided on one side of the loader 1.

[0038] An alkali washing machine box 2 is provided on one side of the feeder 1, and a mixed pickling machine box 3 is connected to one side of the alkali washing machine box 2;

[0039] The vacuum drying system is provided at the rear end of the mixed pickling box 3. A discharge station 12 is provided outside the vacuum drying system. The silicon material can be dried after cleaning. The dried silicon material is transported to the outside by the discharge station, and the cleaning frame is taken out by the staff.

[0040] A hook mechanism 4 is mounted above the alkali cleaning box 2, the mixed pickling box 3 and the discharge station. The hook mechanism 4 can deliver the cleaning frame to each station in sequence without being unhooked;

[0041] An inner immersion component 5 is arranged in the cleaning frame;

[0042] The stepped overflow system is connected between the alkali cleaning box 2 and the mixed acid cleaning box 3.

[0043] In this embodiment, the alkali washing box 2 is sequentially provided with an alkali washing tank 1, an alkali washing tank 2, a neutralization tank and a transition tank;

[0044] The mixed pickling box 3 is sequentially provided with a pickling tank, a quick discharge tank 1, a quick discharge tank 2, a sending tank, an ultrasonic tank 1, an ultrasonic tank 2, an ultrasonic tank 3, and an ultrasonic tank 4, which has a high cleaning effect.

[0045] As a preferred embodiment, the stepped overflow system includes:

[0046] The first auxiliary tank is arranged between the quick discharge tank 1 and the quick discharge tank 2 in the mixed pickling box 3;

[0047] The second auxiliary slot is provided between the second quick discharge slot and the sending slot;

[0048] a third auxiliary tank, connected to the ultrasonic tank 1 and the ultrasonic tank 2, and one side of the third auxiliary tank is connected to the sending tank;

[0049] a fourth auxiliary tank, connected to the third ultrasonic tank, and one side of the fourth auxiliary tank is connected to the second ultrasonic tank;

[0050] The fifth auxiliary tank is connected to the ultrasonic tank four, and one side of the fifth auxiliary tank is connected to the ultrasonic tank three.

[0051] In this embodiment, one side of the quick discharge tank is connected to the neutralization tank in the alkali washing machine box 2. The traditional fully automatic acid-alkali integrated machine adopts the pressure basket overflow water process, and the water consumption of a single device is 5-6 tons per hour. The stepped overflow water process is adopted, and the water consumption of a single device is 3-4 tons per hour. Under the premise of ensuring product quality, water use is effectively reduced to achieve energy saving and consumption reduction.

[0052] In this embodiment, the hook lifting mechanism 4 includes: an upper connecting frame 41, which slides horizontally and is suspended above the inside of the alkali washing machine box 2 and the mixed pickling machine box 3. The upper connecting frame 41 is horizontally transmitted by a transmission chain plate. A frame plate 42 is horizontally arranged below the upper connecting frame 41. Telescopic guide rods 43 are symmetrically fixed on the upper connecting frame 41. The telescopic end of the telescopic guide rod 43 is connected to the frame plate 42. A rotating disk 44 is rotatably arranged below the frame plate 42. A hook frame 45 is connected below the rotating disk 44. A bidirectional rotating motor is installed on the frame plate 42. The output end of the bidirectional rotating motor is connected to the rotating disk 44 for transmission through gear meshing. A non-decoupling process is adopted during the cleaning process, that is, the hook frame can always be hooked on the cleaning frame, and the bidirectional rotating motor is driven by the gears to enable the cleaning frame to be deflected in both directions, thereby improving the cleaning effect.

[0053] In this embodiment, a linear oscillator 46 is further provided between the frame plate 42 and the telescopic guide rod 43. The linear oscillators 46 distributed on the left and right work in synchronous vibration. In particular, the linear oscillator can drive the main body vibration of the cleaning frame during immersion under vibration and telescopic operation.

[0054] As a preferred embodiment, the inner immersion component 5 includes: an inner guide seat 51, which is fixed on the cleaning frame on the left and right sides, and an inner flow tube 52 is fixed laterally and coaxially between the inner guide seats 51. The inner flow tube 52 is arranged to have a double-layer structure, and a plurality of flow holes 53 are distributed circumferentially on the outer ring of the inner flow tube 52, and a plurality of guide members are symmetrically distributed on its inner ring. A ring frame 57 is rotatably arranged between the inner guide seat and the inner flow tube, and a plurality of side rod arms 56 are arranged circumferentially on the ring frame 57, and guide vanes are arranged on the side rod arms 56. A central axis rod 55 is rotatably arranged in the inner flow tube 52, and one end of the central axis rod 55 is fixed to the ring frame 57. It should be noted that silicon material accumulates in the cleaning frame. During immersion, on the one hand, the ring frame can rotate to fully break up the silicon material in the cleaning frame and form a flushing gap. On the other hand, water in the cleaning frame can flow from the flow holes on the inner flow tube to its inner cavity, and then enter the inner flow tube through the guide members.

[0055] In this embodiment, the inner wall cross-section of the inner ring of the inner flow tube 52 is an arc-shaped structure, and a plurality of vortex blades are fixed on the central axis 55. The plurality of vortex blades can cooperate with the arc-shaped inner wall of the inner flow tube to form negative pressure drainage under rotation, thereby realizing the flow of cleaning water in the cleaning frame.

[0056] In this embodiment, a circulation pipe 54 is embedded and fixed in each workstation slot of the alkaline cleaning box 2 and the mixed acid cleaning box 3. The cross-section of the circulation pipe 54 is a U-shaped structure. A circulation pump is connected in series to the circulation pipe 54. In particular, the circulation pipe can realize the circulation of cleaning water in each workstation slot. At this time, the flow of cleaning water in the cleaning frame is coordinated to achieve the effect of flowing and replacing the cleaning water in the cleaning frame, that is, the silicon material cleaning water can enter the inner flow tube after the silicon material is flow-cleaned. At this time, the circulation pipe realizes the replacement of cleaning water in the inner flow tube under the circulation action, thereby achieving a flow cleaning effect and avoiding the re-adhesion of impurity particles.

[0057] Specifically, workers place the cleaning frame on the loader and it is transported by the transmission rack. The hook mechanism can use a non-unhooking process to immerse the cleaning frame into the corresponding slot of each workstation through the telescopic action of the telescopic guide rod. After waiting for the cleaning to be completed, the cleaning frame can be directly lifted away, reducing the time for lifting and placing the basket after unhooking once, thereby effectively adjusting the equipment rhythm and increasing the production capacity of a single device from 35t to 50t. The set stepped overflow water process can effectively make full use of the wastewater of the mixed pickling chassis for the alkaline washing chassis, and use the acidic wastewater of the mixed pickling chassis to supply the alkaline washing chassis, which has a better acid-base neutralization effect and lower water consumption.

[0058] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
