Technical Field:
[0001] The utility model relates to the technical field of silicon material cleaning, in particular to a novel silicon material cleaning basket. Background Art:
[0002] In the photovoltaic silicon material cleaning industry, usually there is an oxide layer and metal ions on the surface of the silicon material. It is necessary to first use acid solution to clean to remove the oxide layer and metal ions on its surface, and then perform water rinsing to achieve the purpose of cleaning thoroughly.
[0003] Currently, generally a larger single-layer plastic square basket is used to hold polycrystalline silicon block materials, and a smaller single-layer plastic square basket is used to hold polycrystalline silicon crushed materials and put them into an ultrasonic cleaning device for ultrasonic cleaning. To avoid the accumulation of polycrystalline silicon crushed materials affecting the cleaning effect, only a small amount of polycrystalline silicon crushed materials can be held in each plastic square basket, resulting in low cleaning efficiency; in order to increase the cleaning amount of silicon materials, operators can only put multiple plastic square baskets into the ultrasonic cleaning device, which is cumbersome to operate, time-consuming and laborious, and occupies a large space, and cannot make reasonable use of the ultrasonic cleaning device. Content of the Utility Model:
[0004] The purpose of the utility model is to provide a novel silicon material cleaning basket.
[0005] The purpose of the utility model is implemented by the following technical solution: A novel silicon material cleaning basket, which includes a connection component, a limiting handle, a material holding frame, a support plate, a spring and two vertical plates; between the two vertical plates with opposite surfaces, a number of the connection components are fixedly arranged at intervals from top to bottom in sequence. A placement channel is formed between every two adjacent connection components. The material holding frame is inserted into each placement channel. A number of spaced support plates are respectively arranged in the connection component below each material holding frame. The spring is vertically arranged on the support plate, and the top end of the spring abuts against the bottom of the material holding frame; on each strip-shaped plate of the connection component above each material holding frame, the limiting handle is rotatably installed, and the top edge of the material holding frame abuts against the cylinder of the limiting handle.
[0006] Preferably, each connection component includes two strip-shaped plates with opposite and spaced surfaces. The two ends of each strip-shaped plate are fixedly connected to the corresponding vertical plate; a number of support plates with vertically arranged surfaces are fixedly arranged at intervals along the length direction between the surfaces of the two strip-shaped plates.
[0007] Preferably, the limiting handle includes a knob, a rotating shaft and the cylinder; one end of the rotating shaft is fixedly connected to the knob, the other end of the rotating shaft rotatably passes through the corresponding strip-shaped plate and is fixedly connected to the center of the end face of the cylinder, and the side surface of the cylinder is rotatably placed on the top edge of the material holding frame.
[0008] Preferably, handles are respectively fixed on the top of the board surfaces on the relatively outer sides of the two vertical boards.
[0009] Preferably, a first through hole is provided through the middle of the board surfaces on the relatively outer sides of the two vertical boards.
[0010] Preferably, a second through hole is formed through the side wall of the material containing frame on the side close to the limiting handle.
[0011] Preferably, a plurality of third through holes are evenly formed at the bottom of the material holding frame.
[0012] The advantages of the utility model are as follows: the utility model assembles two vertical plates into a frame structure through a connecting component, and a storage channel is formed between each two adjacent connecting components. A material holding frame for holding polysilicon fragments is inserted in each storage channel. The material holding frame adopts a drawer-type design. The use of a multi-layer material holding frame can increase the material holding capacity, reduce the number of plastic square baskets used, and effectively utilize the space in the cleaning equipment. The polysilicon fragments are placed in layers, which can reduce material accumulation. In addition, each material holding frame is placed on a spring in the storage channel, and the tip of the knob of the limit handle is used to prevent the material holding frame from leaving the storage channel. After the ultrasonic cleaning is started, the entire silicon material cleaning basket vibrates. Due to the buffering effect of the spring, the material holding frame can swing up and down in the storage channel, and while the material holding frame vibrates up and down, it also swings back and forth between the limit handles relatively arranged at the front and rear of the connecting component, so that the polysilicon fragments in the material holding frame are fully in contact with the cleaning liquid, avoiding the impact of the cleaning effect due to the immobility of the polysilicon fragments.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] As Figures 1-4 shown, a new type of silicon material cleaning basket includes a connecting component 1, a limiting handle 2, a material receiving frame 3, a support plate 4, a spring 6, and two vertical plates 7;
[0021] Between the two vertical plates 7 with opposite plate surfaces, a number of connecting components 1 are fixedly arranged at intervals from top to bottom. The two vertical plates 7 are assembled into a frame structure through the connecting component 1. In this embodiment, three connecting components 1 are fixedly arranged between the two vertical plates 7 from top to bottom. A storage channel 8 is formed between every two adjacent connecting components 1. A material receiving frame 3 is inserted into each storage channel 8. The silicon material is contained in the material receiving frame 3. Two opposite side surfaces of the material receiving frame 3 are respectively in contact with the inner plate surfaces of the vertical plates 7. Second through holes 3.1 are respectively formed through the top parts of the other two opposite side surfaces of the material receiving frame 3. Through the second through holes 3.1, it is convenient for the operator to grasp the material receiving frame 3 and move it in the storage channel 8. A number of third through holes 3.2 are evenly formed at the bottom of the material receiving frame 3, which is beneficial for the cleaning liquid to quickly pass through the material receiving frame 3 and improve the cleaning effect of the silicon material; First through holes 7.1 are respectively formed through the middle parts of the opposite outer plate surfaces of the two vertical plates 7. On the one hand, it can reduce the overall weight of the silicon material cleaning basket. On the other hand, it is beneficial for the cleaning liquid to quickly enter the inside of the silicon material cleaning basket and improve the cleaning effect; Handles 9 are respectively fixed at the top parts of the opposite outer plate surfaces of the two vertical plates 7, which is convenient for lifting and carrying the silicon material cleaning basket;
[0022] Each connecting assembly 1 includes two strip plates 1.1 with vertical, opposite and spaced surfaces, and both ends of each strip plate 1.1 are fixedly connected to corresponding vertical plates 7. Between the two strip plates 1.1 below each material holding frame 3, a plurality of support plates 4 with vertical surfaces are fixedly fixed in the length direction, and each support plate 4 is vertically arranged with the strip plates 1.1. A fixing plate 5 is horizontally fixed on the top of the support plate 4, and a spring 6 is vertically fixed on the surface of the fixing plate 5. The top of the spring 6 abuts against the bottom of the material holding frame 3. On the one hand, the spring 6 supports the material holding frame 3; on the other hand, when ultrasonic cleaning of silicon material is used, the spring 6 plays a buffering role to assist the material holding frame 3 to vibrate up and down.
[0023] A limit handle 2 is rotatably installed on each strip plate 1.1 above the material holding frame 3. In this embodiment, two limit handles 2 are rotatably installed on each strip plate 1.1. The two relatively arranged limit handles 2 can limit the material holding frame 3 from leaving the storage channel 8. The limit handle 2 includes a knob 2.1, a rotating shaft 2.2 and a cylinder 2.3. One end of the rotating shaft 2.2 is fixedly connected to the knob 2.1, and the other end of the rotating shaft 2.2 rotates through the corresponding strip plate 1.1 and the cylinder 2.3. .3 is fixedly connected at the center of the end face, and the side face of the cylinder 2.3 is rotated and placed on the top edge of the material holding frame 3. When the material holding frame 3 needs to be inserted into the storage channel 8, the knob 2.1 is rotated so that the tip of the knob 2.1 faces upward, and the material holding frame 3 is inserted into the storage channel 8, and the bottom of the material holding frame 3 is placed on the spring 6. The knob 2.1 is released. Due to its own gravity, the tip of the knob 2.1 turns to the downward direction, and the tip of the knob 2.1 can prevent the material holding frame 3 from leaving the storage channel 8.
[0024] Working process: put polysilicon scraps into the material holding frame 3, turn the knob 2.1 so that the tip of the knob 2.1 faces upward, insert each material holding frame 3 into the corresponding storage channel 8, and place the bottom of the material holding frame 3 on the corresponding spring 6, release the knob 2.1, and due to its own gravity, the tip of the knob 2.1 turns to the downward direction, and the tip of the knob 2.1 blocks the material holding frame 3 from leaving the storage channel 8;
[0025] The entire silicon material cleaning basket is placed in an ultrasonic cleaning device, and the cleaning liquid first enters the storage channel 8 from the periphery of the silicon material cleaning basket, and then enters the material holding frame 3 from the top of the material holding frame 3 and the third through hole 3.2 to contact the polysilicon fragments;
[0026] After the ultrasonic cleaning is started, the entire silicon material cleaning basket vibrates. Since the spring 6 acts as a buffer, the material frame 3 can swing up and down in the storage channel 8. While the material frame 3 vibrates up and down, it also swings back and forth between the limit handles 2 relatively arranged at the front and rear of the connecting component 1, so that the polysilicon fragments in the material frame 3 are fully in contact with the cleaning liquid, avoiding affecting the cleaning effect due to the accumulation of polysilicon fragments.
[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
