Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic silicon material processing, and in particular to a photovoltaic silicon material trough body conveying device. Background Art

[0002] In the production process of solar photovoltaic panels, photovoltaic silicon materials need to be processed. In the process, hydrofluoric acid is used to pickle the surface of the photovoltaic silicon material, and then water is used to remove the hydrofluoric acid on the surface of the silicon material. The treated silicon material has its surface oxide layer washed away, thereby ensuring the quality of the product in the subsequent production process of solar photovoltaic panels.

[0003] The pickling and water washing of photovoltaic silicon materials are located in different areas. After the photovoltaic silicon materials are pickled in the pickling area, they need to be transferred to the water washing area for water washing. The existing transfer method adopts the method of cooperating with a truss and a manipulator, that is, the pickling truss manipulator and the water washing truss manipulator share a set of walking tracks, which means that the pickling truss manipulator and the water washing truss manipulator can run to the same position in the middle of the walking track to perform material shifting and transfer work.

[0004] In this case, the pickling truss robot and the water-washing truss robot require very rigorous electrical program control and multi-level safety protection measures to ensure that the two robots do not collide in space, and the program logic is relatively complex; at the same time, the operating area of ​​the pickling truss robot and the operating area of ​​the water-washing truss robot cannot be completely physically isolated, and the acid gas evaporated in the equipment will diffuse and flow throughout the equipment, affecting the effect of the material after pure water cleaning in the later stage; therefore, a photovoltaic silicon material conveying and transfer device that can effectively isolate the pickling area from the water-washing area, thereby ensuring the cleaning effect of photovoltaic silicon materials, is an existing problem that needs to be solved. Utility Model Content

[0005] The purpose of the utility model is to provide a photovoltaic silicon material trough conveying device to address the deficiencies of the above-mentioned prior art, so as to isolate the pickling area from the water washing area during the transportation of photovoltaic silicon materials, thereby preventing hydrofluoric acid gas from diffusing from the pickling area to the water washing area, thereby affecting the water washing effect.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a photovoltaic silicon material trough conveying device, comprising a trough body, wherein a partition is arranged above the trough body, and the partition separates the top of the trough body into a feed end and a discharge end which are isolated from each other; water is contained in the trough body, and the water level in the trough body is higher than the lower end of the partition; a conveying mechanism is installed at the bottom of the trough body, and the photovoltaic silicon material is conveyed from the feed end to the discharge end through the conveying mechanism.

[0007] Furthermore, a water inlet is provided on the trough body, and a drain outlet is provided at the bottom of the trough body.

[0008] Furthermore, a liquid level gauge installation opening is provided on the tank body, and a liquid level gauge is installed through the liquid level gauge installation opening.

[0009] Furthermore, the conveying mechanism includes a driving motor, which is located at one end of the trough body and connected to the driving shaft. A driven shaft is arranged at the other end of the trough body, and sprockets are arranged on the driving shaft and the driven shaft, and a chain plate is installed through the sprocket.

[0010] Furthermore, the drive shaft is rotatably sealed to the tank body.

[0011] Furthermore, the driving shaft includes a first driving shaft and a second driving shaft, and the first driving shaft and the second driving shaft are connected via a coupling.

[0012] Furthermore, the first drive shaft and the second drive shaft are both provided with sprockets, the sprockets on the drive shaft and the sprockets on the driven shaft cooperate with each other, and two chain plates are installed through the sprockets on the drive shaft and the driven shaft.

[0013] The beneficial effects of the utility model include: isolation between the photovoltaic silicon material pickling area and the water washing area is achieved, so that acid gas from the pickling is prevented from diffusing into the water washing area, thereby effectively ensuring the effect of the water washing.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] Embodiments of the present utility model:

[0021] like Figure 1-3 As described, a water inlet 11 is provided on the trough body 1 of the conveying trough in this embodiment, and a drain outlet 12 is provided at the bottom of the trough body 1. At the same time, a liquid level gauge installation port 13 is also provided on the trough body 1, and a liquid level gauge is installed through the liquid level gauge installation port 13 (a tubular liquid level gauge is installed through the upper and lower liquid level gauge installation ports 13).

[0022] A partition 2 is arranged above the tank body 1, which divides the top of the tank body 1 into two parts: a feed end 3 and a discharge end 4. The feed end 3 is used in conjunction with a pickling truss robot for placing photovoltaic silicon materials, and the discharge end 4 is used in conjunction with a water-washing truss robot for taking out photovoltaic silicon materials.

[0023] A conveying mechanism 5 is used to convey the photovoltaic silicon material from the feed end 3 to the discharge end 4. A driving motor 51 is arranged in the conveying mechanism 5. The driving motor 51 is located at one end of the trough body. The driving motor 51 is connected to a first driving shaft 52. The first driving shaft 52 is rotatably sealed with the trough body 1. The first driving shaft 52 is connected to the second driving shaft 54 ​​through a coupling 53. A driven shaft 55 is arranged at the other end of the trough body 1. Sprockets 56 are arranged on the first driving shaft 52, the second driving shaft 54 ​​and the driven shaft 55. The sprockets 56 cooperate with chain plates 57. The photovoltaic silicon material is placed on the chain plates 57 on both sides through turnover boxes.

[0024] The principle of this utility model is:

[0025] When the utility model is in use, water is added to the tank body 1 through the water inlet 11. During the process, the water amount in the tank body is controlled by the liquid level meter and the drain outlet 12, so that the water in the tank body 1 submerges the lower end of the partition 2, thereby realizing a liquid seal between the feed end 3 and the discharge end 4 above the tank body 1.

[0026] Therefore, during the transportation of photovoltaic silicon materials, the photovoltaic silicon materials are placed from the feed end 3 onto the conveying chain plate 57 in the tank body 1, and then transported underwater to the discharge end 4, and then taken out by the water washing truss robot at the discharge end 4. During the whole process, since the photovoltaic silicon materials are transported underwater and the space above the tank body 1 is isolated by the partition 2, the acid gas of hydrofluoric acid can be effectively prevented from diffusing from the pickling area to the water washing area, thereby ensuring the effect of water washing.

[0027] In the present invention, sprocket 56 and chain plate 57 are involved. Sprocket 56 and chain plate 57 are common structures of existing chain plate conveyors and are not described in detail. At the same time, since hydrofluoric acid is used in the pickling of photovoltaic silicon materials, and hydrofluoric acid is highly corrosive, the material of the entire equipment needs to be hydrofluoric acid-resistant material, and the commonly used monel400 alloy can be used in the process to ensure the stable operation of the equipment; in addition, the first drive shaft 52 and the second drive shaft 54 ​​are connected by a coupling 53 to facilitate maintenance and replacement of the equipment.
