Description

Technical Field

[0001] The utility model relates to the technical field of silicon slag production, in particular to a novel evaporation device for silicon slag mixed slurry. Background Technique

[0002] With the rapid development of the silicon industry, a large amount of silicon slag is generated during the production and processing of silicon. These silicon slags usually exist in the form of mixed slurry, which contains various useful components and impurities. In order to achieve resource recycling and environmental protection, it is crucial to effectively process the silicon slag mixed slurry. In the past, the treatment methods for silicon slag mixed slurry were often inefficient and difficult to achieve ideal results. Traditional evaporation devices have many problems when treating silicon slag mixed slurry. Among them, the most important problem is that during the evaporation process of silicon slag, hot gas will be wasted, and it is not easy to export the condensed silicon slag. Based on this, we designed an evaporation device for silicon slag mixed slurry that is convenient for discharging, so as to improve the discharging efficiency and the recovery of hot gas.

Detailed implementation manners

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.

[0025] As Figures 1-7 shown, a new type of silicon residue mixed slurry evaporation device includes a fixed bracket 1, a feeding bracket 4, a feeding support 11 and an evaporation mechanism 5. The fixed bracket 1 is a rectangular frame structure, and a feeding bracket 4 and a feeding support 11 are respectively arranged at both ends of the fixed bracket 1. An evaporation mechanism 5 is arranged on the upper part of the fixed bracket 1. The evaporation mechanism 5 includes an evaporation box 501, a first sealing cover 502, an evaporation chamber 511, a stirring bracket 510 and a first drive motor 509. An evaporation chamber 511 is arranged inside the evaporation box 501, and the bottom of the evaporation chamber 511 is connected to a heating tank. The heating tank is connected to a heater 2 through a first air duct 504. A stirring bracket 510 is arranged inside the evaporation chamber 511, and the main shaft of the stirring bracket 510 is connected to a second sprocket 508 on the first drive motor 509 through a first sprocket 506 and a chain 507. A first sealing cover 502 and a hot gas recovery box 9 are arranged on the upper part of the evaporation box 501. The hot gas recovery box 9 is connected to the evaporation box 501 through a second air duct 10.

[0026] It should be noted that in order to recycle the silicon slag mixed slurry, the best way is to dry the mixed slurry. After the water is dried, the silicon slag is exported to achieve recycling. The existing design method generally directly heats the mixed slurry in the evaporation bin, and it is easy to condense during the heating process, resulting in difficult discharging. Moreover, the direct heating method will cause waste of hot air flow. Based on this, we have designed a device that is convenient for hot air recovery and discharging, thereby improving the evaporation efficiency.

[0027] It should be further noted that in order to evaporate the silicon slag mixed slurry, we have designed an evaporation mechanism 5. Among them, an evaporation bin 511 is arranged inside the evaporation box 501, and the evaporation bin 511 is arranged above the heating tank. The hot air is introduced into the heating tank through the heater 2 to heat and evaporate the silicon slag mixed slurry inside the evaporation bin 511. Moreover, in order to improve the evaporation efficiency, we have designed a stirring support 510, which can be driven by the first driving motor to improve the drying efficiency.

[0028] As Figures 2-6 shown, the evaporation bin 511 is a cylindrical cavity structure with openings at both ends, and a guide plate 512 is arranged inside the evaporation bin 511. A guide groove structure is formed between the two guide plates 512; a spiral guide rod 513 is arranged inside the guide groove. One end of the spiral guide rod 513 is connected to the bearing seat 516 on one side of the evaporation box 501. A second driving motor 514 is arranged on the bearing seat 516, and the second driving motor 514 is connected to the main shaft of the spiral guide rod 513 through a coupling to form a guiding mechanism; a feeding support 11 is arranged below the discharge port 515 of the spiral guide rod 513.

[0029] It should be noted that in order to achieve automatic discharging, we have designed a guide plate 512 on the inner wall of the evaporation bin 511, and a guide groove structure is formed by the two guide plates 512. The silicon slag condensed by evaporation can be exported through the spiral guide rod 513 to achieve automatic export, thereby realizing automatic discharging.

[0030] As Figures 1-6 shown, a feed port 503 is arranged on the upper part of the sealing cover 502. The feed port 503 is connected to the feed port of the evaporation bin 511 through a guide groove. One end of the feed port 503 is connected to the discharge end of the feeding support 4; a feeding belt 6 is arranged inside the feeding support 4, and several guide plates are arranged on the upper part of the feeding belt 6. A third driving motor 7 is arranged at one end of the feeding support 4; a protective support 8 is arranged on one side of the first sprocket 506 and the chain 507.

[0031] It should be noted that, in order to achieve automatic feeding, we designed a loading bracket 4, which can achieve automatic feeding under the drive of the third driving motor 7, and introduce the material into the feeding port 503 and then into the evaporation chamber 511 to realize automatic feeding.

[0032] It should be further noted that, in order to improve the safety performance during operation, we set a protective bracket 8 on one side of the first sprocket 506 and the chain 507 to play a protective role.

[0033] As Figure 1 and Figure 7 shown, the hot gas recovery box 9 includes a box body 901, an annular diversion pipe 902 and a second sealing cover 903. The annular diversion pipe 902 is arranged inside the box body 901, and the annular diversion pipe 902 is connected to the second gas guide pipe 10. The second sealing cover 903 is arranged on the upper part of the box body 901; an inlet and an outlet are arranged on the upper part of the box body 901.

[0034] It should be noted that, in order to recover the hot gas flow, we set a hot gas recovery box body 901 on the upper part of the first sealing cover 502, which can collect the hot gas flow led out after heating through the annular diversion pipe 902 inside the box body 901 and conduct circular diversion for heating the internal water stains, so as to realize the recovery of the hot gas.

[0035] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
