Description

Technical Field

[0001] This utility model relates to the technical field of ceramic production equipment, specifically to a ceramic glaze pretreatment feeding device. Background Technology

[0002] In workshop production, glaze pretreatment is a prerequisite for ensuring the quality of the final product. However, currently widely used pretreatment processes and equipment have significant shortcomings in terms of efficiency, energy consumption, and environmental protection, mainly reflected in the following core issues: First, the process flow is fragmented, resulting in low overall efficiency. Traditional glaze preparation requires multiple independent devices to complete functions such as batching, mixing, sieving, drying, and iron removal step by step. This not only leads to a long production line layout, large footprint, and high equipment investment costs, but also the repeated transfer and waiting of materials between different devices greatly prolongs the production cycle and reduces overall production efficiency.

[0003] Secondly, poor mixing and purification effects negatively impact product quality. During multiple transfers, the density differences of various raw materials easily lead to stratification and segregation, resulting in poor uniformity of the mixture before entering the ball mill, directly affecting the chemical stability of the glaze. Simultaneously, traditional fixed iron removal equipment and open screening processes have limited ability to remove fine impurities and are prone to secondary contamination. These residual impurities ultimately form defects such as black spots and pinholes on the ceramic surface, reducing the yield of high-quality products.

[0004] Furthermore, it consumes enormous amounts of energy and causes severe environmental pollution. Traditional drying equipment generally has low thermal efficiency in the drying process of damp raw materials, resulting in the direct emission of large amounts of high-temperature exhaust gas and causing serious energy waste. Simultaneously, at multiple open operation points such as feeding and conveying, large amounts of dust escape uncontrollably into the workshop environment, not only causing raw material loss but also seriously threatening the occupational health of operators, which runs counter to the requirements of green production. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a ceramic glaze pretreatment feeding device. By highly integrating multiple raw material feeding, mixing, screening, drying, iron removal, buffering, and energy recovery functions into a continuous system, it achieves a "one-stop" processing from raw material input to stable supply to the ball mill. This greatly simplifies the production line layout, shortens the process chain, and significantly improves the processing capacity per unit time and overall production efficiency.

[0006] This utility model is achieved using the following technical solution: The ceramic glaze pretreatment feeding device includes a primary raw material hopper and a heat exchange dust suppression box. The primary raw material hopper is connected to the feeding hopper via a feeding box. The feeding hopper is connected to the heating and impurity removal conveying box via a vibrating screen. The heating and impurity removal conveying box is connected to the buffer silo via an elevator. The buffer silo is connected to the ball mill via a pipeline. The heat exchange dust suppression box is connected to the heating and impurity removal conveying box via a blower.

[0007] The ceramic glaze pretreatment feeding device further includes a secondary raw material hopper, which is connected to the feeding box and located above the feeding box. The primary raw material hopper has staggered material guiding and dustproof plates inside, and the feeding box has staggered material guiding and mixing plates inside.

[0008] The primary raw material hopper is equipped with a guide dustproof plate. Its staggered structure slows down the falling speed of the raw materials, effectively reducing the impact dust generated during feeding. The guide mixing plate in the feeding box achieves preliminary mixing without energy consumption by forcing the material flow to cross and overlap, utilizing gravitational potential energy.

[0009] The secondary raw material hopper has the same structure as the primary raw material hopper, and a vibrator is provided on the outside of the hopper.

[0010] The heating and impurity removal conveying box is equipped with a rotary iron remover and a heater. The rotary iron remover is located below the vibrating screen and is equipped with a magnet.

[0011] The rotating iron remover inside the heated impurity removal conveyor box drives the raw material to tumble through its own rotation, allowing all surfaces of the raw material to come into contact with the magnet. Compared with traditional fixed magnetic plates, the iron removal efficiency and thoroughness are greatly improved.

[0012] The heating and impurity removal conveyor box is equipped with a conveyor belt located below the rotary iron remover.

[0013] The heating and dust removal conveying box is equipped with a hot air inlet and a hot air outlet. The heat exchange and dust removal box is equipped with a heat exchange and dust removal box coil. The heat exchange and dust removal box coil is connected to a temperature controller through a blower. The temperature controller is connected to the hot air inlet through a pipe.

[0014] The heat exchange dust settling box combines the functions of a settling dust collector and an air-to-air heat exchanger. Its spacious structure facilitates dust settling at low flow rates; the built-in heat exchange dust settling box coils provide a large heat exchange area in a compact manner, ensuring efficient heat recovery.

[0015] The hot air outlet is connected to the heat exchange dust box via an induced draft fan. The buffer silo is equipped with a buffer silo inlet. The interior of the buffer silo is equipped with a conical mixer. The surface of the conical mixer is equipped with staggered baffles. The conical mixer is located below the buffer silo inlet.

[0016] The key feature is the conical mixer inside the buffer silo. As material falls from above, it is guided to the sides by the conical structure, avoiding central accumulation and dead zones. The baffles on the surface of the cone act like stirring rods, further dispersing and mixing the falling material. This prevents material segregation and breaks up arches, ensuring uniform and smooth discharge.

[0017] Compared with the prior art, the beneficial effects of this utility model are: (1) By highly integrating functions such as multi-raw material feeding, mixing, screening, drying, iron removal, buffering and energy recovery into a continuous system, a "one-stop" processing from raw material input to stable feeding into the ball mill is realized. This greatly simplifies the production line layout, shortens the process chain, and significantly improves the processing capacity per unit time and overall production efficiency.

[0018] (2) By setting up a multi-stage online mixing structure such as a guide mixing plate and a conical mixer, synchronous and efficient mixing of materials is achieved during the conveying process, effectively avoiding stratification and segregation in traditional transfer and ensuring the uniformity of glaze composition. At the same time, by adopting a high-efficiency rotary iron remover, the material is fully tumbled and magnetically separated without dead angles, significantly improving the impurity removal effect, ensuring the purity of the glaze from the source, and helping to improve the yield of the final product.

[0019] (3) Through the unique heat exchange dust suppression box and hot air circulation system, the heat of high-temperature waste gas during the drying process is recovered and reused, which greatly reduces the drying energy consumption and saves production costs. In addition, through the closed design and negative pressure control of key dust-generating points, the escape of dust is effectively suppressed, the workshop working environment is significantly improved, and clean production that is energy-saving and environmentally friendly is achieved.

[0021] To make the objectives and technical solutions of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1 like Figure 1 As shown, the ceramic glaze pretreatment feeding device includes a primary raw material hopper 1 and a heat exchange dust suppression box 10. The primary raw material hopper 1 is connected to a feeding hopper 4 via a feeding box 3. The feeding hopper 4 is connected to a heating and impurity removal conveying box 6 via a vibrating screen 5. The heating and impurity removal conveying box 6 is connected to a buffer silo 8 via an elevator 7. The buffer silo 8 is connected to a ball mill 9 via a pipeline. The heat exchange dust suppression box 10 is connected to the heating and impurity removal conveying box 6 via a blower 12. The primary raw material hopper 1 is equipped with a guide dustproof plate 14, whose staggered structure slows down the falling speed of the raw material and effectively reduces the impact dust generated during feeding. The guide mixing plate 15 in the feeding box 3 achieves preliminary mixing without power consumption by forcing the material flow to cross and overlap, utilizing gravitational potential energy. It also includes a secondary raw material hopper 2, which is connected to the feeding box 3 and is located above the feeding box 3. The primary raw material hopper 1 is equipped with staggered guide dustproof plates 14, and the feeding box 3 is equipped with staggered guide mixing plates 15. The secondary raw material hopper 2 has the same structure as the primary raw material hopper 1, and a vibrator 16 is installed on the outside of the discharge hopper 4. For example... Figure 2 As shown, the heating and impurity removal conveyor box 6 is equipped with a rotary iron separator 18 and a heater 19. The rotary iron separator 18 is located below the vibrating screen 5, and a magnet 25 is installed on the rotary iron separator 18. A conveyor belt 17 is also located inside the heating and impurity removal conveyor box 6, below the rotary iron separator 18. The heating and impurity removal conveyor box 6 is equipped with a hot air inlet 20 and a hot air outlet 21. The heat exchange dust collection box 10 is equipped with a heat exchange dust collection box coil 24, which is connected to a temperature controller 13 via a blower 12. The temperature controller 13 is connected to the hot air inlet 20 via a pipe. Figure 3 As shown, the hot air outlet 21 is connected to the heat exchange dust box 10 via the induced draft fan 11. The buffer silo 8 is provided with a buffer silo inlet 22. The buffer silo 8 is provided with a conical mixer 23 inside. The surface of the conical mixer 23 is provided with staggered baffles 26. The conical mixer 23 is located below the buffer silo inlet 22.

[0023] The above-mentioned ceramic glaze pretreatment feeding device includes the following steps during operation: (1) Two different ceramic raw materials are added to the primary raw material hopper 1 and the secondary raw material hopper 2 respectively. The blower 11, the blower 12, the vibrating motor of the vibrating screen 5, the conveyor belt 17, the drive motor of the rotary iron remover 18 and the elevator 7 are turned on. The target temperature of the heater 19 is set by the temperature controller 13, and is set between 80℃ and 140℃ according to the moisture content of the raw materials. The two raw materials fall from the primary raw material hopper 1 and the secondary raw material hopper 2 to the feed box 3 under the action of gravity. During the falling process, the raw material flow is repeatedly cut and overlapped by the staggered guide mixing plates 15 to achieve the first preliminary mixing. The mixed material enters the feed hopper 4, and the vibrator 16 on its outer side generates high-frequency vibration to prevent the material from arching and blocking in the hopper. The material falls evenly onto the vibrating screen 5 below, and impurities with excessive particle size are screened out and discharged through a special discharge port. (2) The material that has passed through the screen continues to fall and enters the heating and impurity removal conveying box 6. First, the material falls onto the rotating magnetic separator 18, where ferromagnetic impurities are attracted by magnets 25 during the tumbling process. Then, the material falls onto the conveyor belt 17 below. During conveyor transport, the material is heated and dried by heater 19 and hot air blown in from hot air inlet 20. The high-temperature, high-humidity, dust-laden exhaust gas generated during drying is drawn in by the induced draft fan 11 and enters the heat exchange dust settling box 10 through hot air outlet 21. Inside the box, the gas velocity decreases, and dust settles due to gravity. Simultaneously, the high-temperature gas flows past the outside of the heat exchange dust settling box coil 24, heating it. Meanwhile, blower 12 blows ambient temperature air into the heat exchange dust settling box coil 24. The air is preheated as it flows through the coil, and after being regulated by temperature controller 13, it enters the heating and impurity removal conveying box 6 from hot air inlet 20, forming an energy-saving hot air circulation. (3) The qualified material after drying and iron removal is conveyed by conveyor belt 17 to the bottom of elevator 7 and lifted to the buffer silo 8 at a higher position. The material enters from the feed port 22 of the buffer silo and impacts the conical mixer 23 below. The material slides down the conical surface and is further dispersed and disturbed by the baffles 26 on the surface, realizing a second fine mixing, while effectively preventing the material from caking and "rat hole" phenomenon in the silo. The discharge port at the bottom of the buffer silo 8 is connected to the ball mill 9 through a pipe. Since the silo stores a sufficient amount of uniformly mixed material, it can provide a stable and continuous supply to the downstream ball mill 9.
