Detailed Description

As shown in figure 1, the silicon seed crystal cleaning lifting basket comprises a fixed material discharging plate 1 with the thickness of 20mm, a side plate 2 with the thickness of 10mm, a movable material discharging plate 3 with the thickness of 20mm and a reinforcing rod 4. Two side plates 2 which are vertical to each other are fixed on two sides of the fixed discharging plate 1, the side plates 2 can not only discharge materials but also play a role in reinforcing when the discharging plate 1 is fixed. Two ends of the reinforcing rod 4 are respectively integrally formed with an insert rod 401, and the diameter of the insert rod 401 is smaller than that of the reinforcing rod 4; at least one insertion hole 10 is arranged above the two side plates 2, and the insertion rods 401 at the two ends of the reinforcing rod 4 are movably inserted into the corresponding insertion holes 10 respectively. The fixed material placing plate 1 is matched with the two reinforcing rods 4, so that the two side plates 2 can be completely fixed, and the two side plates 2 are prevented from deforming or moving. The handle 9 is arranged above the side plate 2, so that the carrying and moving basket is convenient. A movable discharging plate 3 parallel to the fixed discharging plate 1 is movably arranged between the two side plates 2 above the fixed discharging plate 1 from bottom to top; all set up the blowing groove 5 that a plurality of degree of depth is 15mm at the upper surface of fixed blowing board 1 and activity blowing board 3, seted up a plurality of weeping through-hole 6 respectively in the bottom of every blowing groove 5, the weeping through-hole 6 of blowing groove 5 bottom, the acidizing fluid flows when convenient washing, and puts a seed crystal in every blowing groove 5, has avoided colliding with each other between the seed crystal. Two strip-shaped holes 7 which are mutually vertical to the movable material placing plates 3 are respectively arranged on the two side plates 2, and a plurality of clamping grooves 8 which are mutually vertical to the strip-shaped holes 7 are arranged on one side wall of each strip-shaped hole 7; two ends of the movable material placing plate 3 are respectively fixed with a hanging lug 301 matched with the clamping groove 8, and the hanging lugs 301 are movably clamped in the clamping grooves 8. The width of the strip-shaped hole 7 is slightly larger than the width of the hanging lug 301 of the movable material placing plate 3, so that the hanging lug 301 can slide from the strip-shaped hole 7 to the clamping groove 8 to fix the movable material placing plate 3. A limiting block 801 is fixedly arranged at one end, close to the strip-shaped hole 7, of the clamping groove 8 and used for fixing the hanging lug 301 and preventing the hanging lug from sliding out of the clamping groove 8. Prying holes 802 are formed in the bottom of the clamping groove 8, and when seed crystals are cleaned, prying rods are inserted into the prying holes 802, so that the movable material placing plate 3 can be conveniently taken out of the clamping groove 8. The fixed feeding plate 1 and the movable feeding plate 3 are made of plastic materials, and the seed crystals are not easy to damage in the cleaning process due to the fact that the plastic materials are soft, so that the quality of products is guaranteed.

The working principle is as follows:

when cleaning, seed crystals are placed in the discharging grooves 5 of the fixed discharging plate 1, and each discharging groove 5 is provided with one seed crystal; then, the movable material placing plate 3 on the second layer is installed, the movable material placing plate 3 needs to be obliquely extended to the middle of the two side plates 2, the hanging lugs 301 on the two sides are extended to the rear of the strip-shaped hole 7 and can be horizontally placed and vertically moved, the hanging lugs 301 on the two sides can be moved back and forth after being moved to the designated position, and the hanging lugs 301 are placed into the clamping grooves 8. After the seed crystal is installed, the seed crystal is placed, and the rest can be done in the same way. After baiting groove 5 was all filled with, installation anchor strut 4, then put into the acidizing fluid with the hand-basket, the hand-basket was rocked in the sideslip about, under the acidizing fluid effort, the seed crystal was controlled in baiting groove 5 and is rolled, reached comprehensive abluent effect, and because 5 only place a seed crystal in every baiting groove, can not collide with each other, lead to the seed crystal to scrap. And (4) carrying out snap overflow rinsing and ultrasonic overflow rinsing after the pickling time is up, shaking the lifting basket in the rinsing process, and finally drying, inspecting and packaging.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
