Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a silicon micro powder drying device. Background Technology

[0002] Silica powder, also known as microsilica, or silica fume, is a type of dust emitted during the high-temperature smelting of industrial silicon and ferrosilicon in industrial electric furnaces. This dust is collected and processed using a special collection device. Microsilica can fill the pores between cement particles and react with hydration products to form a gel. It also reacts with alkaline materials like magnesium oxide to form a gel. Silica powder is produced from natural quartz or fused quartz through multiple processes including crushing, ball milling, flotation, acid washing and purification, and high-purity water treatment. Silica powder is a non-toxic, odorless, and pollution-free inorganic non-metallic material with high temperature and corrosion resistance, as well as high thermal conductivity. Drying is required during the processing of microsilica powder.

[0003] In existing silicon powder drying equipment, hot air comes into direct contact with the silicon powder during the drying process, which can easily lift the silicon powder particles and spread them throughout the drying chamber, causing scale buildup on the inner wall of the drying chamber and increasing subsequent cleaning costs. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing silicon powder drying device that, during the drying process, hot air directly contacts the silicon powder, which easily lifts the silicon powder particles and spreads them throughout the drying chamber, causing scale buildup on the inner wall of the drying chamber and increasing subsequent cleaning costs. Therefore, this invention proposes a silicon powder drying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a silicon micropowder drying device, comprising a drying assembly, wherein a covering assembly and a rotating assembly are provided inside the drying assembly, the drying assembly includes a drying chamber, heating chambers are installed on both sides of the drying chamber, a heater is installed on the top of the heating chamber, heating pipes are connected to both ends of the heater, a fan is installed on the heating chamber, sliding grooves are symmetrically installed on the inner side of the drying chamber, a drying box is slidably installed inside the sliding groove, the covering assembly includes a protective cover, the protective cover is disposed on the top of the drying box, an insertion groove is installed on the side of the drying box, an insertion block is installed on the side of the protective cover, and the insertion block penetrates through the interior of the insertion groove.

[0006] Preferably, the rotating assembly includes a rotating motor, the top of which is connected to a rotating shaft, and multiple scrapers are distributed on the outer side of the rotating shaft, the scrapers being disposed inside the drying box.

[0007] Preferably, a protective frame is provided on the outside of the fan, and an air inlet is connected to the side of the heating box.

[0008] Preferably, the drying chamber has an air outlet on its side.

[0009] Preferably, a door is installed on the side of the drying oven, and hinges are symmetrically installed between the door and the drying oven.

[0010] Preferably, support columns are installed at the four corners of the bottom of the drying oven.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by placing the protective cover on the top of the drying box, the insert block is inserted into the insert slot. The protective cover helps to reduce the diffusion of silicon micro powder inside the drying box, thereby reducing the adhesion of silicon micro powder to the inner wall of the drying box and reducing the subsequent cleaning cost. At the same time, the protective cover has multiple through holes, which prevent silicon micro powder particles from flying away while allowing hot air to penetrate to ensure the drying effect.

[0013] 2. In this utility model, the rotating shaft is driven by a rotating motor to rotate, which in turn drives the scraper to rotate. The rotation of the scraper also drives the silicon powder inside the drying box to rotate, which increases the contact area between the silicon powder and the hot air, accelerates the evaporation rate of moisture, reduces uneven drying in some areas, improves the uniformity of drying, and thus improves the drying efficiency.

[0019] 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.

[0020] 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.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a silicon micropowder drying device, including a drying component 1, a covering component 2 and a rotating component 3 arranged inside the drying component 1, the drying component 1 including a drying chamber 101, heating chambers 102 installed on both sides of the drying chamber 101, a heater 103 installed on the top of the heating chamber 102, heating pipes 104 connected to both ends of the heater 103, a fan 105 installed on the heating chamber 102, a sliding groove 107 symmetrically installed on the inner side of the drying chamber 101, a drying box 108 slidably installed inside the sliding groove 107, the covering component 2 including a protective cover 201, the protective cover 201 being disposed on the top of the drying box 108, an insertion groove 203 installed on the side of the drying box 108, an insertion block 202 installed on the side of the protective cover 201, the insertion block 202 penetrating the interior of the insertion groove 203, a protective frame 106 arranged on the outer side of the fan 105, and an air inlet 109 connected to the side of the heating chamber 102.

[0022] In this embodiment, the heater 103 operates to cause the heating tube 104 to release heat evenly. Simultaneously, the fan 105 operates to blow hot air into the drying chamber 101 through the air inlet 109, thereby drying the silicon micropowder. The movable drying box 108, positioned inside the sliding groove 107, facilitates removal from the drying chamber 101, enabling convenient handling of the silicon micropowder. Placing the protective cover 201 on top of the drying box 108 causes the insert block 202 to be inserted into the insert slot 203. The protective cover 201 helps reduce the diffusion of silicon micropowder inside the drying chamber 101, thus reducing silicon micropowder adhesion to the inner wall of the drying chamber 101 and lowering subsequent cleaning costs. Furthermore, the protective cover 201 has multiple through holes, preventing silicon micropowder particles from scattering while allowing hot air to penetrate to ensure the drying effect.

[0023] Example 2: As Figures 1-4As shown, the rotating assembly 3 includes a rotating motor 301, a rotating shaft 302 connected to the top of the rotating motor 301, a plurality of scrapers 303 distributed on the outer side of the rotating shaft 302, the scrapers 303 being disposed inside the drying box 108, an air outlet being provided on the side of the drying box 101, a door being installed on the side of the drying box 101, hinges being symmetrically installed between the door and the drying box 101, and support columns being installed at the four corners of the bottom of the drying box 101.

[0024] In this embodiment, the rotating shaft 302 is driven to rotate by the rotating motor 301, which in turn drives the scraper 303 to rotate. The rotation of the scraper 303 also drives the silicon powder inside the drying box 108 to rotate, which increases the contact area between the silicon powder and the hot air, accelerates the evaporation rate of moisture, reduces uneven drying in some areas, improves the uniformity of drying, and thus improves the drying efficiency.

[0025] The working principle of this embodiment is as follows: In use, the drying box 108 is first moved inside the sliding groove 107, facilitating its removal from the drying chamber 101 and enabling convenient handling of the silicon micropowder. Then, the protective cover 201 is placed on top of the drying box 108, causing the insert block 202 to be inserted into the insert slot 203. The heater 103 then operates, causing the heating tube 104 to release heat evenly. Simultaneously, the fan 105 works to blow hot air into the drying chamber 101 through the air inlet 109. Inside the drying chamber 101, the silicon powder is dried. The protective cover 201 helps reduce the diffusion of silicon powder inside the drying chamber 101, thereby reducing the amount of silicon powder adhering to the inner wall of the drying chamber 101. At the same time, the rotating shaft 302 is driven by the rotating motor 301 to rotate, which in turn drives the scraper 303 to rotate. The rotation of the scraper 303 helps to rotate the silicon powder inside the drying chamber 108, increasing the contact area between the silicon powder and the hot air, accelerating the evaporation rate of moisture, and improving the drying efficiency.

[0026] The heater 103, heating tube 104, fan 105, rotating motor 301 and rotating shaft 302 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the heater 103, heating tube 104, fan 105, rotating motor 301 and rotating shaft 302 will not be explained in detail.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present 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 the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
