DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 6 The utility model provides a technical solution: a cooling and ventilation device for metal silicon production, comprising an outer shell 1, the outer shell 1 comprises a shell body 101, one end of the upper surface of the shell body 101 is connected to a feed pipe 102, a conveyor belt 3 is fixedly installed between the inner walls on both sides of the shell body 101, the feed pipe 102 is located above one end of the conveyor belt 3, a discharge port is provided on the surface of one end of the shell body 101, the other end of the conveyor belt 3 extends to the outside of the shell body 101 through the discharge port, and a plurality of multi-directional air-cooling components 2 are fixedly installed between the inner walls on both sides of the shell body 101 and above the conveyor belt 3, each multi-directional air-cooling component 2 comprises two mounting plates 201, a plurality of fan mechanisms are arranged between the two mounting plates 201, the plurality of fan mechanisms are connected to the driving mechanism, and each multi-directional air-cooling component 2 also comprises a lifting and adjusting mechanism.

[0026] In a specific embodiment, a plurality of evenly distributed holes 301 are formed on the surface of a transport belt portion of the conveyor belt 3. When the metal silicon raw material transported on the conveyor belt 3 is cooled by air through the multi-directional air cooling component 2, the active airflow generated inside the shell 101 by the multi-directional air cooling component 2 will also pass through the holes 301 from below and contact the metal silicon raw material, thereby achieving multi-directional cooling and improving the cooling efficiency.

[0027] See also Figure 1 and Figure 3A guide block 103 is fixedly connected to the inner wall of one end of the shell 101 and is located above one end of the conveyor belt 3. When raw materials are added into the shell 101 through the feed pipe 102, the raw materials enter from the feed pipe 102 and fall onto the conveyor belt 3 under the guidance of the guide block 103. The raw materials are guided by setting the guide block 103.

[0028] Furthermore, a plurality of evenly distributed ventilation holes 104 are provided on the inner walls on both sides of the shell 101. The ventilation holes 104 can ensure that the inside and outside of the shell 101 are connected, thereby ensuring air circulation.

[0029] Furthermore, filters 105 are fixedly installed on the inner walls of both sides of the shell 101 at positions corresponding to the ventilation holes 104. The filter 105 can prevent the air inside the shell 101 from flowing through the ventilation holes 104 and bringing out fine impurities and dust in the metallic silicon raw material when the multi-directional air cooling component 2 is working.

[0030] Furthermore, the bottom edge of the feed pipe 102 is located on the inner wall of the shell 101 and is elastically rotatably connected to a baffle 106 through a torsion spring. The area of ​​the baffle 106 is larger than the bottom opening of the feed pipe 102. Under the action of the torsion spring, the baffle 106 will be normally closed to the bottom opening of the feed pipe 102 to prevent dust from overflowing from the feed pipe 102 when the metallic silicon is cooled. When raw materials are added to the feed pipe 102, the raw materials press the baffle 106 to rotate downward. After the raw materials enter the interior of the shell 101, the baffle 106 is reset under the drive of the torsion spring.

[0031] Furthermore, universal wheels 107 are fixedly installed at the four corners of the bottom surface of the housing 101. The universal wheels 107 can be provided to facilitate the movement of the entire device, thereby providing convenience in use.

[0032] See also Figures 4 to 6 Each fan mechanism includes a frame 202, a through slot is provided in the middle of the frame 202, a mounting ring 203 is fixedly installed in the through slot through a connecting piece, a rotating shaft 204 is rotatably installed in the mounting ring 203, and a plurality of fan blades 205 are evenly arranged in a ring shape on the outer wall of one end of the rotating shaft 204. When the rotating shaft 204 rotates, the fan blades 205 at one end thereof are driven to rotate, thereby generating an airflow to supply air for cooling the metal silicon raw material. Using natural wind to cool the metal silicon can prevent the high-temperature metal silicon raw material from suddenly encountering water, which may disrupt the molecular structure of the metal silicon and cause damage to the process, thereby improving the quality of the metal silicon finished product.

[0033] Furthermore, several frames 202 are fixedly connected by connecting plates 206, and the two frames 202 located at both ends are rotatably connected to the surface of one side of the mounting plate 201 on the corresponding side through a connecting shaft 207. A second motor 212 is fixedly installed on the inner wall of one side of one mounting plate 201, and one end of the output shaft of the second motor 212 is fixedly connected to one end of the connecting shaft 207 on the corresponding side through a through hole provided on the surface of one side of the mounting plate 201. When the second motor 212 is started, all fan mechanisms can be driven to perform independent angle adjustments between the mounting plates 201 on both sides, so that in actual use, the windward angle of the metal silicon can be adjusted according to specific needs, thereby obtaining a larger windward area to improve cooling efficiency.

[0034] Furthermore, one end of another connecting shaft 207 is rotatably mounted in a through hole provided on one side surface of the mounting plate 201 on the other side and extends through the through hole to the other side of the corresponding mounting plate 201 and is fixedly mounted with a driving mechanism, the driving mechanism comprising a first motor 211, the first motor 211 is fixedly mounted on one end of the connecting shaft 207 on the corresponding side, a second sprocket 210 is fixedly sleeved on one end of the output shaft of the first motor 211, a chain 209 is sleeved on the second sprocket 210, and a plurality of first sprockets 208 are connected to each other through the chain 209, each first sprocket 208 is fixedly sleeved on one end of the corresponding rotating shaft 204 The first motor 211 is fixedly mounted on one end of a connecting shaft 207 on one side, and the connecting shaft 207 is rotatably connected to the mounting plate 201, so the first motor 211 can follow the connecting shaft 207 to independently rotate synchronously with the fan mechanism, and when the first motor 211 is started, the second sprocket 210 can be driven to rotate, and all the first sprockets 208 can be driven to rotate synchronously through the transmission of the chain 209, so that all the rotating shafts 204 drive the fan blades 205 to rotate to generate airflow, and a plurality of rotating shafts 204 can be driven by a first motor 211, thereby reducing energy consumption during use and saving use costs.

[0035] Furthermore, the lifting and lowering adjustment mechanism includes two slide bars 214, which are respectively fixedly mounted on the inner walls on both sides of the housing 101. A slide groove 213 adapted to the slide bar 214 is provided on the surface of one side of the two mounting plates 201 and is slidably connected to the slide bar 214 through the slide groove 213. A third motor 215 is fixedly mounted on the inner wall of one side of the mounting plate 201. A gear 216 is fixedly sleeved on one end of the output shaft of the third motor 215. The gear 216 is meshed and connected with a toothed plate 217 on one side. The toothed plate 217 is fixedly mounted on the inner wall of one side of the housing 101 and is located on one side of the corresponding slide bar 214. Starting the third motor 215 can drive the gear 216 to rotate. The mounting plates 201 on both sides are slidably connected with the corresponding slide bars 214 through the slide grooves 213. The meshing connection between the gears 216 and the toothed plates 217 can drive the mounting plates 201 on both sides and the fan mechanism therebetween to slide up and down along the extension direction of the slide bars 214. After the third motor 215 is powered off, it will be self-locking and the meshing relationship between the gears 216 and the toothed plates 217 will make the fan assembly as a whole hover at a certain height. The distance between the fan mechanism and the conveyor belt 3 can be adjusted through the lifting and lowering adjustment mechanism, so that the flow rate of the cooling air contacting the metal silicon raw material or the windward area of ​​the metal silicon raw material can be increased according to actual needs, thereby reducing limitations in use.

[0036] Working principle: high-temperature metallic silicon raw materials are poured into the shell 101 through the feed pipe 102, and the raw materials are guided by the guide block 103 and fall onto the conveyor belt 3 for relatively slow transportation. During the transportation process, the first motor 211 in the multi-directional air-cooling components 2 drives all the fan blades 205 to rotate to generate airflow to naturally cool the metallic silicon raw materials transported on the conveyor belt 3, so as to avoid the sudden cooling of the high-temperature raw materials by water or cold air, which may disrupt the molecular structure of metallic silicon and affect the quality of the finished metallic silicon products. While the fan blades 205 generate airflow for air cooling, the second motor 212 can be started to adjust the angle of the fan mechanism relative to the conveyor belt 3, and the height of the fan mechanism from the conveyor belt 3 can be adjusted by the third motor 215, so that the metallic silicon raw materials can be cooled by air from the most suitable height and angle according to actual needs, thereby improving the cooling efficiency.

[0037] It should be noted that the specific models and specifications of the conveyor belt 3, the first motor 211, the second motor 212, and the third motor 215 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0038] The power supply and principles of the conveyor belt 3, the first motor 211, the second motor 212, and the third motor 215 are clear to those skilled in the art and will not be described in detail herein.

[0039] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
