Description

Technical Field

[0001] This utility model relates to the field of glass production, and in particular to a microcrystalline glass raw material screening device. Background Technology

[0002] Glass-ceramics, also known as glass ceramics, are polycrystalline solid-phase materials containing glass, which are produced by controlled nucleation and crystallization of base glass with certain specific compositions at a certain temperature. Utilizing the mechanical and thermal properties of glass-ceramics, such as high temperature resistance, thermal shock resistance, and adjustable thermal expansion, various materials that meet mechanical requirements can be manufactured, and they have been widely used in various fields.

[0003] A search revealed a Chinese patent publication number CN219025027U, which discloses a white microcrystalline glass raw material screening device. This patent uses a rotating stirring frame to stir a mixture of quartz sand and some metals in the glass raw material. A vibrating electromagnet works in conjunction with the stirring frame to achieve dual separation of impurities, further enabling precise screening of quartz sand of different sizes and dimensions, thus separating the most suitable glass raw material for processing. The device includes a main housing and a collecting frame with an upward-opening collecting chamber. The material enters the collecting chamber, automatically separating impurities and some unqualified quartz sand, eliminating the need for subsequent cleaning and ensuring efficiency and stability. However, current white microcrystalline glass raw material screening processes suffer from problems such as particle compression, causing larger particles to become stuck in the sieve holes, affecting the sieve's throughput for a certain period. Furthermore, the raw material accumulates upon entering the screening device from the feed inlet, only spreading out after a screening period, which also affects screening efficiency.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1 — Figure 6 As shown, a microcrystalline glass raw material screening device includes a screening cylinder 101 with several sieve holes 102 at its bottom. A connecting frame 103 is bolted to the side of the screening cylinder 101, and a support plate 104 is bolted to the connecting frame 103. A support column 105 is bolted to the bottom of the support plate 104. A rotating mechanism is provided on the screening cylinder 101, including a motor 201 mounted on the ground. The output end of the motor 201 is connected to a main shaft 202 via a coupling. Several stirring shafts 204 are bolted to the main shaft 202. The stirring shafts 204 are movably disposed inside the screening cylinder 101. A feeding mechanism is detachably provided on the screening cylinder 101, including a cover plate 301 detachably mounted on the screening cylinder 101 via quick-release bolts. A sealing plate 302 is bolted to the bottom of the cover plate 301. The design of 02 improves the sealing performance of the screening cylinder 101. A hopper 303 is bolted to the cover plate 301, and a feeding assembly is rotatably connected to the bottom of the hopper 303. A lifting mechanism is movably mounted on the connecting frame 103. The lifting mechanism includes a lifting frame 401, and a main shaft 202 passes through the center of the lifting frame 401 and is rotatably connected to the screening cylinder 101. Several guide rods 403 are bolted to the top of the lifting frame 401. The guide rods 403 are slidably connected to the connecting frame 103, and a limiting piece 404 is bolted to the top of the guide rods 403. Several unblocking columns 402 are bolted inside the lifting frame 401. The number of unblocking columns 402 is the same as the number of screen holes 102 and they are located on the same vertical line. The unblocking columns 402 can be inserted into the screen holes 102 from bottom to top to ensure that the screen holes 102 are unblocked and that all screen holes 102 are in a smooth state, which is beneficial to improving screening efficiency.

[0026] In this embodiment, the bottom of the lifting frame 401 is bolted with a number of evenly distributed lifting blocks 405 arranged in a ring. The side of the main shaft 202 is bolted with a rotating shaft 203 that cooperates with the lifting blocks 405. As the rotating shaft 203 rotates with the main shaft 202, it will squeeze the lifting blocks 405 each time it passes the position of the lifting blocks 405, causing the lifting blocks 405 and the lifting frame 401 to be lifted up. This allows the unblocking column 402 on the lifting frame 401 to be inserted into the sieve hole 102, ensuring the normal screening process.

[0027] In this embodiment, a waste box 407 is bolted to the outside of the lifting frame 401. Several screening holes 406 are opened on the bottom side of the lifting frame 401. The screening holes 406 are used to discharge small particulate matter. As the lifting frame 401 moves up and down, the raw material falling from the screening hole 102 will move randomly in the lifting frame 401. Small particulate impurities will be discharged from the screening hole 406 and enter the waste box 407.

[0028] In this embodiment, the feeding assembly includes a rotating shell 304, which is rotatably connected to the bottom of the screening cylinder 101. An inclined plate 305 is bolted inside the rotating shell 304, and a discharge frame 306 is welded to the side of the rotating shell 304.

[0029] In this embodiment, the bottom of the rotating shell 304 is bolted to a plug-in frame 307, and the top of the main shaft 202 is bolted to a plug-in block 205 that cooperates with the plug-in frame 307. The plug-in block 205 cooperates with the plug-in frame 307, which can drive the rotating shell 304 to rotate synchronously when the main shaft 202 rotates, so that the glass raw material is spilled from the discharge frame 306 of the rotating shell 304 and evenly spread in the screening cylinder 101.

[0030] Working Principle: In use, the cover plate 301 is installed on the screening cylinder 101, and the insertion block 205 is aligned with the insertion frame 307. The microcrystalline glass raw material to be screened is fed into the hopper 303 via the conveying device. The motor 201 is turned on, and the motor 201 drives the rotating shaft 203, stirring shaft 204, and insertion block 205 to rotate via the main shaft 202. The insertion block 205 drives the rotating shell 304 to rotate synchronously via the insertion frame 307, causing the glass raw material to be discharged from the discharge frame 306 of the rotating shell 304 and evenly spread inside the screening cylinder 101. The stirring shaft 204 rotates inside the screening cylinder 101, agitating the microcrystalline glass. Particles larger than the sieve holes 102 remain inside the screening cylinder 101, while particles smaller than the sieve holes 102 fall through the sieve holes 102 into the lower part of the screen. Inside the lifting frame 401, each time the rotating shaft 203 rotates past the position of the lifting block 405, it will squeeze the lifting block 405, causing the lifting block 405 and the lifting frame 401 to lift. The lifting frame 401 is lifted upward by the lifting force of the lifting block 405 and moves upward along the direction of the guide rod 403, causing the unblocking column 402 on the lifting frame 401 to insert into the sieve hole 102. At the same time, the particles inside the lifting frame 401 will also move irregularly due to the inertia of the up and down. At this time, the small particles and impurities in the lifting frame 401 will be discharged from the sieve hole 406 and enter the waste box 407. Finally, the large particles are stored in the screening cylinder 101, the qualified microcrystalline glass raw materials are stored in the lifting frame 401, and the small particles and impurities are stored in the waste box 407. After removing the cover plate 301, the staff can use the suction device to classify and collect particles of different sizes.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
