Abstract
Description
Technical Field
[0001] This utility model relates to the field of silica mud drying technology, specifically a silica mud drying device based on freeze drying. Background Technology
[0002] In the crystalline silicon industry, the silicon material manufacturing process involves many steps, and the last step is often the drying of the silicon material. As the last step in the cleaning process, the drying of silicon material can effectively remove dirt and impurities from the surface of the silicon material. Therefore, the drying of silicon material is a key step that determines the quality of the product. It can effectively dry the water residue on the surface of the silicon material, which is beneficial to the purification of the silicon material.
[0003] In current social life, when silica mud is dried by heat, it loses moisture and becomes highly susceptible to dust dispersion. However, the high strength and resistance of silica mud caused by freeze-drying effectively solves the problem of heat exchange and air convection disturbing the silica mud, greatly reducing dust generation. However, existing freeze-drying systems usually cannot freely assemble the racks for transporting silica mud for freeze-drying according to the amount of silica mud to be processed. Therefore, we need a silica mud drying device based on freeze-drying. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a freeze-drying-based silica mud drying device, which solves the problem that existing silica mud freeze-drying systems cannot freely assemble the shelves for transporting silica mud for freeze-drying according to the amount of silica mud to be processed.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a silica mud drying device based on freeze-drying, comprising a fixed base, foot pads fixedly connected to the bottom of the fixed base near the four corners, a drying device body fixedly installed on the top of the fixed base, a cover plate fixedly installed at one end of the drying device body, a conveying mechanism fixedly installed inside the drying device body, a control box fixedly connected to the top of the fixed base, and a guardrail fixedly connected to the top of the fixed base.
[0006] Preferably, the conveying mechanism includes a fixed base plate, four support rods are fixedly connected to the top of the fixed base plate, a plurality of bearing plates are fixedly connected between the outer walls of one side of the four support rods, and a baffle is fixedly connected to the top of each of the bearing plates.
[0007] Preferably, the bottom surface of the main body of the drying device is fixedly connected to two fixed plates, the top of each of the two fixed plates is provided with a movable groove, and the bottom of the fixed base plate is fixedly connected to two movable blocks that are adapted to the movable groove.
[0008] Preferably, a first connecting plate is fixedly connected to one outer wall of the support plate, and a connecting groove is formed on one outer wall of the first connecting plate. A second connecting plate that matches the connecting groove is fixedly connected to the other outer wall of the support plate.
[0009] Preferably, the outer walls of both sides of the first connecting plate are slidably connected with limiting blocks, and one end of the limiting block extends into the interior of the connecting groove. One end of each of the two limiting blocks is fixedly connected with an extension plate, and one outer wall of each of the two extension plates is fixedly connected with a handle. The outer walls of both sides of the second connecting plate are provided with limiting grooves that are adapted to the limiting blocks.

[0011] Beneficial effects
[0012] This invention provides a silica mud drying device based on freeze-drying. Compared with the prior art, it has the following advantages:
[0013] (1) When using the freeze-drying-based silica mud drying device, the operator can place the silica mud to be processed on the support plate and then put the conveying mechanism into the interior of the drying device body. The movable block at the bottom of the fixed base plate can slide in the movable groove, which facilitates the support plate to transport the silica mud to the interior of the drying device body. The baffle can prevent the silica mud from falling off the surface of the support plate during the transportation process.
[0014] (2) When the freeze-drying-based silica mud drying device needs to be spliced together, the operator can make the second connecting plate on one side of the bearing plate correspond to the first connecting plate on the other side of the bearing plate, and then pull the extension plate by the handle so that the limiting block on the side of the extension plate will not affect the insertion of the second connecting plate. After the second connecting plate is inserted into the first connecting plate, the handle is released. At this time, the stretched return spring can move through the extension plate with the limiting block, so that one end of the limiting block is inserted into the limiting groove on the side of the second connecting plate, thereby completing the connection between the first connecting plate and the second connecting plate, realizing the free splicing of multiple shelves, and solving the problem that the existing silica mud freeze-drying negative pressure drying cannot freely splice the shelves for freeze-drying silica mud according to the amount of silica mud to be processed.

Several bearing plates 23 are fixedly connected between the outer walls of one side of the four support rods 22. The top of the bearing plates 23 is used to place the silica mud to be processed. Each of the bearing plates 23 has a baffle 231 fixedly connected to its top. The baffle 231 prevents the silica mud from falling off the surface of the bearing plate 23. Two fixed plates 16 are fixedly connected to the bottom of the drying device body 12. The top of each of the two fixed plates 16 has a movable groove 161. Two movable blocks 211 that are adapted to the movable groove 161 are fixedly connected to the bottom of the fixed base plate 21.
[0023] A first connecting plate 24 is fixedly connected to one outer wall of the support plate 23. A connecting groove 241 is formed on one outer wall of the first connecting plate 24. A second connecting plate 25, which is adapted to the connecting groove 241, is fixedly connected to the other outer wall of the support plate 23. A limiting block 26 is slidably connected to both outer walls of the first connecting plate 24, and one end of the limiting block 26 extends into the interior of the connecting groove 241. An extension plate 27 is fixedly connected to one end of each of the two limiting blocks 26. A handle 271 is fixedly connected to one outer wall of each of the two extension plates 27. 271 facilitates the pulling of the limiting block 26 via the extension plate 27. The outer walls of both sides of the second connecting plate 25 are provided with limiting grooves 251 that are adapted to the limiting block 26. Several return springs 28 are fixedly connected to one side of the outer wall of both extension plates 27, and one end of the return spring 28 is fixedly connected to one side of the outer wall of the first connecting plate 24.
