Description

Technical Field

[0001] This utility model belongs to the field of float glass production equipment, specifically relating to a stirring device for a float glass kiln. Background Technology

[0002] The forming process of float glass production is completed in a tin bath purged with a protective gas. Molten glass flows continuously from the furnace and floats on the surface of the relatively dense molten tin. Under the influence of gravity and surface tension, the molten glass spreads and flattens on the molten tin surface, forming a smooth upper and lower surface. After hardening and cooling, it is guided onto a transition roller table. The rollers on the table rotate, pulling the glass strip out of the tin bath and into the annealing furnace. After annealing and cutting, flat glass products are obtained.

[0003] The main raw material for float glass is silica (quartz sand), supplemented with sodium carbonate (soda ash), limestone (providing calcium oxide), and dolomite (providing magnesium oxide and calcium oxide), among other auxiliary materials. Before float glass production, the raw materials need to be mixed. The process involves workers pouring the required raw materials into a mixing tank, where they are stirred by the agitator blades. However, existing agitators do not mix the materials thoroughly enough. If a large amount of material is added, some material may remain on the side of the mixing tank, or be located on the side wall during stirring, failing to contact the agitator blades and thus resulting in insufficient mixing and poor mixing effect.

[0004] In view of this, in order to solve the above-mentioned technical problems, this utility model proposes a stirring device for a float glass furnace that can uniformly feed and stir while feeding, and can scrape the material on the side wall of the stirring tank into the middle for uniform stirring. The device has a simple structure, is easy to operate, ensures uniform mixing of float glass raw materials, and improves the mixing effect. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] See Figures 1-5A stirring device for a float glass furnace includes a support frame 1 and a stirring tank 2 mounted on the support frame 1. The stirring tank 2 contains a stirring assembly 3 for stirring materials. Scraping assemblies 4 are respectively installed between the two side walls of the stirring tank 2 on both sides of the stirring assembly 3. Fixed frames 5 are vertically mounted at both ends of the stirring tank 2, and the fixed frames 5 are bolted to the ends of the stirring tank 2. A storage hopper 6 is fixed between the two fixed frames 5, positioned directly above the stirring tank 2. A discharge opening and closing assembly 7 is located at the lower end of the storage hopper 6. The stirring assembly 3, the scraping assembly 4, and the discharge opening and closing assembly 7 are electrically connected to a controller. Specifically… By using the storage bin 6 located directly above the mixing tank 2, and by feeding raw materials from the storage bin 6 into the mixing tank 2, the raw materials are directly fed from the storage bin 6 onto the mixing assembly 3 for mixing. This avoids the raw materials accumulating or adhering to the sides of the mixing tank 2 during the initial mixing process. In addition, the scraper components 4 located on both sides of the mixing assembly 3 can push the materials that accumulate or adhere to the sides of the mixing tank 2 during the mixing process to the center for mixing. Furthermore, the discharge opening and closing component 7 allows for the continuous and small-scale feeding of raw materials from the storage bin 6 into the mixing tank 2, thereby achieving thorough mixing of various raw materials and greatly improving mixing efficiency.

[0022] The preferred scraping assembly 4 includes a mounting bracket 401, a reciprocating motor 402, a bidirectional screw 403, a guide rod 404, a nut 405, a scraper 406, and a U-shaped frame 407. Mounting brackets 401 are respectively provided on the upper outer sides of both ends of the mixing tank 2. The mounting brackets 401 are detachably connected to both ends of the mixing tank 2 by bolts. The bidirectional screw 403 and the guide rod 404 are rotatably mounted between the two mounting brackets 401, with the guide rod 404 located inside the mixing tank 2. The reciprocating motor 402 is mounted on the mounting bracket 401, and its output shaft is connected to the bidirectional screw 403. Nuts 405 are symmetrically fitted onto the bidirectional screw 403. Two U-shaped frames 407 are symmetrically arranged, with one vertical part of the U-shaped frame 407 slidingly fitted onto the guide rod 404 and the other vertical part fixedly connected to the nut 405. The lower side of the guide rod 406... A scraper 406 is fixedly connected to the U-shaped frame 407, and one side of the scraper 406 is in contact with the inner wall of the mixing tank 2. The reciprocating motor 402 is electrically connected to the controller. Specifically, during use, the controller controls the reciprocating motor 402 to work, which drives the bidirectional screw 403 to rotate. At this time, the threaded engagement between the bidirectional screw 403 and the two nuts 405 can drive the two U-shaped frames 407 to move, thereby driving the two scrapers 406 to move towards the middle of the mixing tank 2. During this process, the material located on the side of the mixing tank 2 can be pushed to the middle for mixing by the mixing component 3. When the two scrapers 406 approach each other, the reciprocating motor 402 reverses to make the two scrapers 406 move in opposite directions. This reciprocating motion allows the material on the side of the mixing tank 2 to be mixed with the material in the middle, so that various materials can be fully contacted and mixed.

[0023] The preferred bidirectional screw 403 is located on the outer side of the upper end of the mixing tank 2. This design can prevent materials from adhering to the bidirectional screw 403 during the mixing process and causing damage.

[0024] The preferred mixing assembly 3 includes a mixing motor 301, a mixing shaft 302, and mixing blades 303. The mixing shaft 302 is rotatably disposed between the middle of both ends of the mixing tank 2. The mixing shaft 302 is evenly spaced along its axial direction with a plurality of mixing blades 303, and the mixing blades 303 are inclined and arranged at an angle to the ground. The mixing motor 301 is disposed on the outer side of one end of the mixing tank 2, and the output shaft of the mixing motor 301 is connected to the mixing shaft 302. The mixing motor 301 is electrically connected to the controller. Specifically, in use, the controller controls the mixing motor 301 to work, so that it drives the mixing shaft 302 to rotate, thereby driving the plurality of mixing blades 303 to rotate, so that various materials can be mixed.

[0025] Preferably, a mixing rod 304 is fixedly connected between each pair of mixing blades 303. The mixing rod 304 can increase the contact area of ​​materials during the mixing process and improve the mixing efficiency.

[0026] The preferred storage silo 6 is provided with multiple partition plates 8 to form multiple unit silos 601. By dividing the silo into multiple unit silos 601 through the partition plates 8, various raw materials can be pre-sorted and added in proportion, which can greatly improve work efficiency.

[0027] Each of the preferred unit hoppers 601 has a discharge opening and closing assembly 7 on its outer wall. The discharge opening and closing assembly 7 includes two opening and closing plates 701, symmetrically arranged at the outlet end of the unit hopper 601. The two ends of the two opening and closing plates 701 are rotatably mounted between the two side walls of the discharge end of the unit hopper 601 via pins 702. A protrusion is fixedly provided at the bottom of the unit hopper 601 for the pins 702 to be placed. The two ends of the opening and closing plates 701 are rotatably connected to the protrusion via pins 702, allowing the ends of the opening and closing plates 701 located inside the unit hopper 601 to flip along the side of the unit hopper 601, allowing raw materials to be fed from the unit hopper 601 into the mixing tank 2. Connecting blocks 7 are fixedly connected to the opposite sides of the two opening and closing plates 701. 03. Telescopic cylinders 704 are rotatably installed on both sides of the storage bin 6 corresponding to the unit bin 601. The output ends of the two telescopic cylinders 704 are rotatably connected to the corresponding connecting blocks 703 through connecting ears. The two telescopic cylinders 704 are electrically connected to the controller. Specifically, when feeding materials, the controller controls the telescopic cylinders 704 on both sides of the unit bin 601 to work, so that they pull the two connecting blocks 703. At this time, the end of the opening and closing plate 701 located in the unit bin 601 flips along the side of the unit bin 601. The two opening and closing plates 701 gradually open, allowing the raw materials to be fed into the mixing tank 2. It is worth noting that when feeding materials, the raw materials need to be continuously and in small amounts controlled to enter the mixing tank 2, so as to achieve simultaneous feeding and mixing, and ensure that various raw materials are fully mixed.

[0028] The upper surface of the preferred mixing tank 2 is fixedly provided with an outwardly inclined material protection frame 9, wherein the material protection frame 9 is provided to prevent the material from splashing out of the mixing tank 2 during mixing.

[0029] The working principle of this utility model is as follows: First, various raw materials are put into multiple unit silos 601 for storage in proportion. During the stirring, the controller simultaneously controls the stirring motor 301, two reciprocating motors 402 and the telescopic cylinder 704 that controls the multiple unit silos 601. With their cooperation, various raw materials can be fully mixed and stirred, which greatly improves the stirring efficiency.
