[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figures 1 to 5This utility model provides a reaction device for producing high-purity ultrafine silicon powder, including: a crushing box 101 and two rotating rods 1031. A first horizontal bar 110 is fixedly connected to the outer surface of the crushing box 101 near its bottom, and a second horizontal bar 113 is fixedly connected to the outer surface of the crushing box 101 near its bottom. Two springs 111 are fixedly connected to the outer surface of the first horizontal bar 110, and a limiting telescopic rod 112 is fixedly connected to the outer surface of the first horizontal bar 110. A sieve plate 109 is fixedly connected to the end of the two springs 111 away from the first horizontal bar 110. The outer surface of the sieve plate 109 away from the limiting telescopic rod 112 is in contact with the outer surface of the second horizontal bar 113. A fixing strip 114 is fixedly connected to the outer surface of the crushing box 101 near its bottom. A motor 115 is fixedly connected to the outer surface of the fixing strip 114. A rotating disk 116 is fixedly connected to the output end of the motor 115. A protrusion 117 is fixedly connected to the outer surface of the rotating disk 116. An L-block 118 is fixedly connected to the outer surface of the sieve plate 109, and the sieve plate 109 is located on the outer surface of the L-block 118. The motor 115 is started by an external power source, which drives the rotating disk 116 to rotate. The rotating disk 116 drives the protrusion 117 to rotate. When the protrusion 117 rotates, it... When the L-block 118 moves to one side, the sieve plate 109 moves towards the direction of the spring 111 under the limiting action of the spring 111 and the limiting telescopic rod 112. After moving, under the elastic force of the spring 111, the side of the sieve plate 109 away from the spring 111 hits the surface of the second horizontal bar 113, causing the sieve plate 109 to vibrate. After vibration, the high-purity ultrafine silicon powder on the upper surface of the sieve plate 109 can be screened. Every time the rotating disk 116 rotates, the sieve plate 109 will vibrate once through the protrusion 117 and the L-block 118, and the cycle repeats.

[0025] like Figures 1 to 5 As shown, a motor 103 is fixedly connected to the top of the outer surface of the crushing box 101. One rotating rod 1031 is fixedly connected to the output end of the motor 103, and the other rotating rod 1031 is rotatably connected to the bottom of the inner wall of the crushing box 101 through a bearing. Multiple blades 104 are fixedly connected to the outer surface of both rotating rods 1031, and round shafts are fixedly connected to the top of both rotating rods 1031. Belts 102 are movably sleeved on the outer surface of the two round shafts. High-purity ultrafine silicon powder raw materials are poured into the interior of the crushing box 101 through the feed inlet. Then, the lid is closed, and the motor 103 is started by an external power source. The motor 103 drives the rotating rod 1031 to rotate. At this time, the rotating rod 1031 drives the blades 104 to rotate. The two rotating rods 1031 are connected by belts 102, and the two rotating rods 1031 rotate in the same phase to crush the material.

[0026] like Figures 1 to 5As shown, an inclined plate 108 is fixedly connected to the bottom of the outer surface of the crushing box 101. A discharge port 105 is provided at the bottom of the outer surface of the crushing box 101. Two sliding grooves 106 are provided at the bottom of the outer surface of the crushing box 101. A baffle 107 is slidably connected inside the two sliding grooves 106. The baffle 107 is located directly below the discharge port 105. The area of ​​the baffle 107 is slightly larger than the area of ​​the discharge port 105. When crushing is carried out inside the crushing box 101, pushing or pulling the baffle 107 to slide inside the sliding groove 106 can close or open the discharge port 105. High-purity ultrafine silicon powder slides down the inclined plate 108 onto the surface of the sieve plate 109.

[0027] like Figures 1 to 5 As shown, a hopper 120 is fixedly connected to the bottom of the outer surface of the crushing box 101. The hopper 120 is located directly below the sieve plate 109. A reaction box 119 is set directly below the hopper 120. High-purity ultrafine silicon powder enters the interior of the hopper 120 and then enters the interior of the reaction box 119 for reaction.

[0028] Working Principle: During operation, high-purity ultrafine silicon powder is poured into the crushing chamber 101 through the feed inlet. The lid is then closed, and motor 103 is started by an external power source. Motor 103 drives rotating rod 1031, which in turn drives blade 104. The two rotating rods 1031 are connected by a belt 102 and rotate in the same phase. The crushed high-purity ultrafine silicon powder enters the surface of inclined plate 108 through the bottom chute 106. Simultaneously, during crushing inside the crushing chamber 101, pushing or pulling baffle 107 within the chute 106 closes or opens the discharge port 105. The high-purity ultrafine silicon powder slides down the inclined plate 108 onto the surface of sieve plate 109. Then, motor 115 is started by an external power source, driving the rotation... The rotating disk 116 rotates, which drives the protrusion 117 to rotate. When the protrusion 117 rotates, it drives the L block 118 to move to one side. At this time, the sieve plate 109 moves towards the spring 111 under the limiting position of the spring 111 and the limiting telescopic rod 112. After moving, under the elastic force of the spring 111, the side of the sieve plate 109 away from the spring 111 hits the surface of the second horizontal bar 113, causing the sieve plate 109 to vibrate. After vibration, the high-purity ultrafine silicon powder on the upper surface of the sieve plate 109 can be screened. Every time the rotating disk 116 rotates, it will drive the sieve plate 109 to vibrate once through the protrusion 117 and the L block 118. This cycle repeats. When the sieve plate 109 is not subjected to any external force, the L block 118 is always within the radius of the circular motion trajectory of the rotating disk 116. The high-purity ultrafine silicon powder enters the interior of the hopper 120 and then reaches the interior of the reaction chamber 119 for reaction.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
