This high-purity polycrystalline silicon can improve photoelectric conversion efficiency and increase the power generation of solar panels when manufacturing solar cells or other electronic devices.

[0003] However, an existing adsorption bed with online monitoring function has the following drawbacks: for example, after the adsorption device is installed inside the adsorption bed, the entire adsorption bed needs to be disassembled in order to replace the adsorbent material inside, which reduces the practicality of the device. Summary of the Invention

[0004] The purpose of this application is to enable easy disassembly and replacement of the adsorption device.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: The main body includes a shell, the inner wall of which is equipped with an adsorption mechanism. The adsorption mechanism includes an adsorption bed, the surface of which is fixedly connected to the inner wall of the shell. A monitoring mechanism is installed on the inner wall of the adsorption bed, the monitoring mechanism including a connecting plate. The surface of the connecting plate is in contact with the surface of the adsorption bed, a connecting rod is installed inside the connecting plate, a connecting groove is formed on the lower surface of the adsorption bed, an elastic block is fixedly connected to the inner wall of the connecting groove, the lower surface of the elastic block is in contact with the upper surface of the connecting rod, and a first protrusion is fixedly connected to the surface of the connecting rod.

[0006] As a preferred embodiment, a second protrusion is fixedly connected to the surface of the connecting rod, the second protrusion being located below the first protrusion; a flow sensor is fixedly connected to the lower surface of the connecting plate; a probe is fixedly connected to the upper surface of the flow sensor; and the probe extends through the connecting plate into the interior of the adsorption bed.

[0007] As a preferred embodiment, the surface of the probe is covered with an activated carbon mesh, a second air inlet pipe is fixedly connected to the left side surface of the adsorption bed, and a first air outlet pipe is fixedly connected to the right side surface of the adsorption bed.

[0008] As a preferred embodiment, a spraying mechanism is installed at the end of the first air outlet pipe. The spraying mechanism includes an air pump, the air inlet of which is fixedly connected to the end of the first air outlet pipe, and the air outlet of which is fixedly connected to a second air outlet pipe.

[0009] As a preferred embodiment, a second connecting pipe is fixedly connected to the inner wall of the outer shell. The second connecting pipe is located above the adsorption bed. A second nozzle is fixedly connected to the upper surface of the second connecting pipe. The right side surface of the second connecting pipe is fixedly connected to the end of the second air outlet pipe.

[0010] As a preferred embodiment, a partition is fixedly connected to the inner wall of the outer shell, the partition being located above the second connecting pipe, and a discharge pipe is fixedly connected to the right side surface of the outer shell, the discharge pipe being located above the second air outlet pipe.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] (1) Compared with the prior art, this adsorption bed with online monitoring function, through the connecting rod, elastic block and first protrusion, when the activated carbon mesh needs to be replaced during use, press the connecting rod installed inside the connecting plate upward, so that the elastic block fixed at the top of the connecting rod is compressed and the connecting rod is rotated, so that the first protrusion fixed on the surface of the connecting rod rotates 90 degrees and can be disengaged from the connecting groove. At this time, the connecting plate can be pulled down to disassemble the flow sensor along with the probe and the activated carbon mesh as a whole, and replace the activated carbon mesh. Compared with conventional devices, which require the entire adsorption bed to be disassembled after the adsorption device is installed inside the adsorption bed to replace the adsorbent material inside, reducing the practicality of the device, this device can easily disassemble and replace the activated carbon mesh inside during use, thus improving the practicality of the device.

[0015] (2) Compared with the prior art, this adsorption bed with online monitoring function consists of a second inlet pipe, an adsorption bed body, and an activated carbon mesh. In use, after hydrogen gas is introduced into the interior of the adsorption bed body through the second inlet pipe, the hydrogen gas comes into contact with the surfaces of the activated carbon mesh and the probe. Contact with the surface of the probe allows for flow rate detection, while contact with the activated carbon mesh allows for the adsorption of impurities in the hydrogen gas. As the hydrogen gas flows from the left side to the right side of the adsorption bed body, multiple activated carbon meshes adsorb the hydrogen gas, ensuring the purity of the hydrogen gas and improving the working efficiency of the device.

[0025] like Figures 1-4 An adsorption bed with online monitoring function is shown, comprising a main body 1, which includes a shell 101. An adsorption mechanism 2 is installed on the inner wall of the shell 101. The adsorption mechanism 2 includes an adsorption bed body 201, the surface of which is fixedly connected to the inner wall of the shell 101. A monitoring mechanism 3 is installed on the inner wall of the adsorption bed body 201, including a connecting plate 304. The surface of the connecting plate 304 is in contact with the surface of the adsorption bed body 201. A connecting rod 305 is installed inside the connecting plate 304. A connecting groove 204 is formed on the lower surface of the adsorption bed body 201, and an elastic block 306 is fixedly connected to the inner wall of the connecting groove 204. The lower surface of 6 is in contact with the upper surface of the connecting rod 305. The first protrusion 307 is fixedly connected to the surface of the connecting rod 305. When the activated carbon mesh 303 needs to be replaced, press the connecting rod 305 installed inside the connecting plate 304 upwards. After the elastic block 306 fixed at the top of the connecting rod 305 is compressed, rotate the connecting rod 305. After the first protrusion 307 fixed on the surface of the connecting rod 305 rotates 90 degrees, it can be disengaged from the connecting groove 204. At this time, the connecting plate 304 can be pulled down to disassemble the flow sensor 301 together with the probe 302 and the activated carbon mesh 303 as a whole, and replace the activated carbon mesh 303.

[0026] A second protrusion 308 is fixedly connected to the surface of the connecting rod 305. The second protrusion 308 is located below the first protrusion 307.

A second air inlet pipe 202 is fixedly connected to the left side surface of the adsorption bed 201. A first air outlet pipe 203 is fixedly connected to the right side surface of the adsorption bed 201. After hydrogen gas is introduced into the interior of the adsorption bed 201 through the second air inlet pipe 202, the hydrogen gas comes into contact with the surfaces of the activated carbon mesh 303 and the probe rod 302. Surface contact allows for flow rate detection, while contact with activated carbon mesh 303 adsorbs impurities in the hydrogen. Multiple activated carbon meshes 303 adsorb hydrogen as it flows from the left to the right of the adsorption bed 201, ensuring its purity. A spraying mechanism 4 is installed at the end of the first outlet pipe 203. The spraying mechanism 4 includes an air pump 401, whose inlet is fixedly connected to the end of the first outlet pipe 203. A second outlet pipe 402 is fixedly connected to the outlet of the air pump 401. A second connecting pipe 403 is fixedly connected to the inner wall of the outer shell 101, located above the adsorption bed 201. A second spray nozzle 404 is fixedly connected to the upper surface of the second connecting pipe 403. The right side surface of the housing 101 is fixedly connected to the end of the second air outlet pipe 402. A partition 103 is fixedly connected to the inner wall of the housing 101, and the partition 103 is located above the second connecting pipe 403. A discharge pipe 104 is fixedly connected to the right side surface of the housing 101, and the discharge pipe 104 is located above the second air outlet pipe 402. A first connecting pipe 105 is fixedly connected to the inner wall of the housing 101. A first nozzle 106 is fixedly connected to the lower surface of the first connecting pipe 105. A first air inlet pipe 107 is fixedly connected to the right side surface of the first connecting pipe 105. A first through hole 102 is opened on the left side surface of the housing 101. An adjustment mechanism 5 is installed on the inner wall of the first through hole 102. The adjustment mechanism 5 includes an elastic plate 506, and the surface of the elastic plate 506 is connected to the first through hole 102. The inner wall is fixedly connected, and a feed pipe 505 is installed inside the elastic plate 506. A first through hole 102 is opened on the left side surface of the outer shell 101. An adjustment mechanism 5 is installed on the inner wall of the first through hole 102. The adjustment mechanism 5 includes the elastic plate 506, the surface of which is fixedly connected to the inner wall of the first through hole 102. The feed pipe 505 is installed inside the elastic plate 506. A fixed plate 501 is fixedly connected to the left side surface of the outer shell 101. An electric telescopic rod 502 is fixedly connected to the upper surface of the fixed plate 501. A rotating plate 503 is fixedly connected to the telescopic end of the electric telescopic rod 502. A rotating shaft 504 is slidably connected inside the rotating plate 503. The end of the rotating shaft 504 is movably connected to the surface of the feed pipe 505. The electric telescopic rod 502 is activated.The height of the rotating plate 503 can be adjusted, and the surface of the rotating plate 503 is movably connected to the feed pipe 505 via the rotating shaft 504. When the height of the rotating plate 503 changes, the inclination angle between the feed pipe 505 and the horizontal plane also changes. When the inclination angle between the fixed plate 501 and the horizontal plane increases, the size of the polycrystalline silicon formed by the silicon block particles falling into the housing 101 from the feed pipe 505 is smaller, and vice versa, thereby adjusting the size of the produced polycrystalline silicon.

[0027] Working principle: When the activated carbon mesh 303 needs to be replaced, press the connecting rod 305 installed inside the connecting plate 304 upwards. This compresses the elastic block 306 fixed at the top of the connecting rod 305, causing the connecting rod 305 to rotate. The first protrusion 307 fixed on the surface of the connecting rod 305 rotates 90 degrees and disengages from the connecting groove 204. Then, pull the connecting plate 304 downwards to disassemble the flow sensor 301, along with the probe 302 and the activated carbon mesh 303. Replace the activated carbon mesh 303. After hydrogen gas is introduced into the adsorption bed 201 through the second inlet pipe 202, the hydrogen gas comes into contact with the surfaces of the activated carbon mesh 303 and the probe 302. Contact with the surface of the probe 302 allows for flow detection. The activated carbon mesh 303 can adsorb impurities in the hydrogen gas. As the hydrogen gas flows from the left side to the right side of the adsorption bed 201, multiple activated carbon meshes 303 adsorb the hydrogen gas, ensuring the purity of the hydrogen gas and improving the working efficiency of the device. Activating the electric telescopic rod 502 can adjust the height of the rotating plate 503. The surface of the rotating plate 503 is movably connected to the feed pipe 505 through the rotating shaft 504. When the height of the rotating plate 503 changes, the inclination angle between the feed pipe 505 and the horizontal plane also changes. When the inclination angle between the fixed plate 501 and the horizontal plane increases, the size of the polycrystalline silicon formed by the silicon block particles adsorbed into the shell 101 by the feed pipe 505 is smaller, and vice versa, thereby adjusting the size of the produced polycrystalline silicon.
