[0002] Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. The main material of most solar panels is "silicon". Compared with ordinary batteries and rechargeable batteries, solar cells are more energy-saving and environmentally friendly green products. When producing solar panels, the silicon material needs to be thoroughly cleaned. The cleaning of silicon materials plays a very important role in the entire solar panel manufacturing process. The equipment for cleaning silicon materials on the market can only clean silicon materials alone, and the sand and gravel produced after cleaning is not easy to remove. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a solar cell manufacturing equipment, including a cylinder, wherein a ring seat 1, a ring seat 2 and a ring seat 3 are arranged in sequence inside the cylinder, the bottom ends of the cylinder, the ring seat 1, the ring seat 2 and the ring seat 3 are mounted on a bottom cover, and the top ends of the ring seat 1, the ring seat 2 and the ring seat 3 are mounted on a top cover, wherein a cavity 1 is formed between the cylinder and the ring seat 1, a cavity 2 is formed between the ring seat 1 and the ring seat 2, and a cavity 3 is formed between the ring seat 2 and the ring seat 3, and a discharge pipe 1, a discharge pipe 2 and a discharge pipe 3 are installed at the bottom of the bottom cover, the discharge pipe 1 is connected with the cavity 1, the discharge pipe 2 is connected with the cavity 2, the discharge pipe 3 is connected with the cavity 3, and an outlet is arranged at the bottom of the ring seat 3.

[0005] Furthermore, coaxially distributed blades are installed in the ring seat three, one end of the blade extends outward through the bottom cover, and a power mechanism connected to the blade transmission is installed on the bottom cover. A plurality of nozzles 1, 2 and 3 are respectively provided at the bottom of the skeleton one, skeleton two and skeleton three, and a channel is opened in the bottom cover, the inlet end of the channel is connected to the outlet end of the ring seat three, and the nozzles 1, 2 and 3 are all connected to the channel.

[0006] Furthermore, a through hole is opened in the middle of the bottom cover, a debris removal part is installed in the through hole, a dirt collection box is installed at the outlet of the debris removal part, and the dirt collection box is fixed on the outer side of the bottom cover.

[0007] Furthermore, the impurity removal part is a ring structure, the middle part of which is raised toward one side of the axis, and a plurality of filter holes are provided on the lower inclined surface of the raised part, so that water flows through the raised part into the channel.

[0008] Furthermore, the power mechanism includes a motor and a transmission belt. The motor is fixed to the bottom surface of the bottom cover, and the output end of the motor is transmission-connected to the shaft extending from the blade through the transmission belt.

[0009] Furthermore, control valves are installed on the discharge pipe one, the discharge pipe two and the discharge pipe three.

[0010] A method for preparing a solar cell manufacturing device comprises the following steps:

[0011] Step 1, adding silicon material and cleaning water for producing solar panels through an opening of a cavity formed by a cylinder and a ring seat;

[0012] Step 2: The blades are driven to rotate by a power mechanism. During the rotation of the blades, the clean water stored in the cylinder is driven to converge to the third ring seat. The flowing water drives the silicon material to converge to the third ring seat. Since the filter holes of the sieve plates 1 and 2 in the ring seats 1 and 2 have different apertures, the silicon materials with different diameters can be sorted.

[0013] Step 3: After the water flow driven by the blades enters the dirt collecting box, it passes through the impurity removal part and enters the channel, and is discharged through nozzles 1, 2 and 3, washing the silicon material upward to improve the cleaning effect;

[0014] Step 4: The cleaned silicon material is discharged through discharge pipe 1, discharge pipe 2 and discharge pipe 3.

[0015] The present invention has the following beneficial effects:

[0016] 1. The present invention drives the blades to rotate through a power mechanism. During the rotation of the blades, the clean water stored in the cylinder is driven to converge into the ring seat three, and the flowing water drives the silicon material to converge to the ring seat three. Since the filter holes of the sieve plates one and two in the ring seats one and two have different inner diameters, the silicon materials with different outer diameters can be sorted, and the sorted silicon materials are discharged through the discharge pipe one, the discharge pipe two and the discharge pipe three.

[0017] 2. The dirt collecting box provided in the present invention is a closed cavity. After the water flow driven by the blades enters the dirt collecting box, it passes through the impurity removal part into the channel and is discharged through nozzle one, nozzle two and nozzle three. Since the water outlets of nozzle one, nozzle two and nozzle three are upward, it is convenient to flush away the particles attached to sieve plate one, sieve plate two or sieve plate three, thereby avoiding clogging of the filter holes on sieve plate one, sieve plate two or sieve plate three.

[0018] 3. In the present invention, the water flow containing sand and gravel moves toward the inside of the dirt collecting box through the protrusion in the middle of the impurity removal part, so that the sand and gravel converge toward the middle under the action of inertia, and the water flow passes through the aluminum frame on the lower side slope of the protrusion of the impurity removal part and enters the channel, thereby separating the sand and gravel from the water flow and achieving the purpose of impurity removal.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Step 2: The blades 8 are driven to rotate by the power mechanism 12. During the rotation of the blades, the clean water stored in the cylinder 1 is driven to converge into the ring seat 3 7. The flowing water drives the silicon material to converge into the ring seat 3 7.

[0047] Step 3: After the water flow driven by the blades 8 enters the dirt collecting box 15, it passes through the impurity removal part 14 and enters the channel 21, and is discharged through the nozzle 1 51, the nozzle 2 61 and the nozzle 3 71, washing the silicon material upward to improve the cleaning effect;

[0052] The width of the through slot 172 is the same as the width of the through slot of the spiral blade 173, and the widths of the through slots 172 on the sieve plates 16 with different inner diameters are different.
