Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for refractory brick production, specifically a molding device for refractory bricks. Background Technology

[0002] Refractory bricks are bricks that are resistant to combustion and high temperatures, with a refractoriness typically between 1580℃ and 1770℃. These bricks are mainly made from refractory clay or other refractory raw materials through processes such as batching, molding, and firing. The raw materials for refractory bricks are diverse, including kaolin, refractory clay, high-alumina bauxite, and sillimanite-like natural minerals. Their chemical composition and physical properties determine the quality and characteristics of the refractory material. The shape and size of refractory bricks can be customized as needed, and they can be standard bricks, ordinary bricks, or special-shaped bricks. They are mainly used for lining various industrial kilns, such as blast furnaces, steel furnaces, coke ovens, glass melting furnaces, cement kilns, steam boilers, and various heat treatment furnaces and heating furnaces, serving as the inner lining material for these high-temperature equipment. Refractory bricks undergo various physical and chemical changes and mechanical actions. During construction, refractory products require a specific shape, precise dimensions, and sufficient strength. Molding devices ensure that refractory bricks meet these requirements during the molding process, thus satisfying practical needs. Furthermore, molding is an effective means of improving the microstructure of the product. By pressing the raw materials with a molding device, the particles can be rearranged to achieve a certain density, thereby improving the physical and chemical properties of the product, such as bulk density, apparent porosity, softening temperature under load, thermal shock resistance, compressive strength, and flexural strength. After molding, refractory bricks require subsequent processes such as handling, drying, and firing. Molding devices ensure that the refractory bricks have a stable shape and dimensions after molding, facilitating subsequent processes. Good molding quality can also improve brick stacking efficiency during firing and reduce production costs. Modern molding equipment typically has a high degree of automation, enabling fast and precise molding operations. This not only significantly improves production efficiency and reduces labor input but also minimizes the impact of human error on product quality. The use of molding equipment ensures that refractory bricks are subjected to uniform pressure and stable temperature control during the molding process, thus avoiding quality problems caused by poor molding. Simultaneously, the molding equipment can thoroughly mix and stir the raw materials, ensuring the accuracy and stability of the product formula. In conclusion, molding equipment plays a crucial role in the manufacturing process of refractory bricks, not only meeting the usage requirements of the products but also improving their physical and chemical properties. Furthermore, it can adapt to subsequent process requirements, improve production efficiency, and ensure product quality. Therefore, in the production process of refractory bricks, the selection and use of molding equipment must be emphasized. Current mainstream technologies typically rely on direct filling molding with molds. While effective, this method faces significant challenges in subsequent operation. Specifically, after molding, the initial blank of the refractory brick often exhibits stubborn adhesion to the mold surface. This greatly increases the difficulty of smoothly demolding the blank, affecting production efficiency and product quality. Moreover, during subsequent transportation, because the blank is still in a relatively fragile initial molding state, its structural stability is insufficient, making it prone to deformation, which adversely affects the final shape and performance of the product. To solve these problems…There is an urgent need to explore more advanced and efficient molding and demolding technologies, as well as to adopt more robust packaging and transportation solutions to ensure the integrity and high quality of refractory brick blanks throughout the entire production process. Technological innovation, such as using special coatings to reduce adhesion between the mold and the blank, optimizing mold design and demolding processes, and introducing advanced transportation protection measures, can effectively overcome the above-mentioned problems and improve the automation level and product quality stability of refractory material production. For example, the utility model CN217196049U, "A Molding Device for Refractory Bricks," describes a device that, through the above technical solution, activates a telescopic component. The telescopic component moves a pad plate via a connecting block. The pad plate carries a sliding plate and a horizontal plate upwards in the molding mold. The horizontal plate then pushes the molded refractory brick out of the molding mold. The moving sliding plate separates the horizontal plate and the refractory brick from the pad plate, allowing for easy and labor-saving removal of the refractory brick blank. Simultaneously, a horizontal plate is installed at the bottom of the refractory brick blank to prevent deformation during handling. While existing technologies may already offer solutions to the above problems, this application aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a refractory brick forming device, comprising: a device shell, a main displacement column and an auxiliary displacement column, wherein the main displacement column is installed on the device shell, the auxiliary displacement column is installed on the device shell, a two-stage pressure forming structure is respectively installed on the main displacement column and the auxiliary displacement column, and an auxiliary forming quick demolding component is installed inside the device shell;

[0004] The two-stage pressure forming structure includes: a displacement power chamber, a displacement rotor, a displacement screw, a downward displacement module, a pressing hydraulic rod, a pressing support plate, and a module guide groove.

[0005] The displacement power chamber is installed on the main displacement column, the displacement rotor is installed inside the displacement power chamber and connected to the displacement screw, the displacement screw is installed inside the main displacement column, the main displacement column has a module slide groove, the downward displacement module is inserted into the main displacement column through the module slide groove, and the downward displacement module is fitted on the outside of the displacement screw, the auxiliary displacement column has a module guide slide groove, the downward displacement module is inserted into the module guide slide groove, the pressing hydraulic rod is installed on the downward displacement module and connected to the pressing support plate;

[0006] It should be noted that, as described above, the raw materials for forming refractory bricks are added to the auxiliary forming quick demolding assembly inside the device housing. This drives the displacement rotor in the displacement power chamber on the main displacement column to rotate, which in turn causes the displacement screw to rotate. This causes the downward displacement module to slide downward along the module guide groove on the auxiliary displacement column until the downward displacement module moves to the appropriate position. Then, the pressing hydraulic rod is driven to extend, which in turn causes the pressing support plate to press against the auxiliary forming quick demolding assembly inside the device housing, thereby pressing the refractory brick raw materials into shape.

[0007] Preferably, the auxiliary molding quick demolding component includes: a raw material surrounding frame, several connecting bolt holes, several shell bottom placement grooves, several reset demolding springs, several retaining bolts, several positioning keys, several brick pressing grooves, and several brick blank support plates.

[0008] The raw material surrounding frame is inserted into the device housing. The device housing and the raw material surrounding frame are respectively provided with a plurality of connecting bolt holes. The device housing is provided with a plurality of bottom mounting grooves. A plurality of reset and demolding springs are respectively installed in the plurality of bottom mounting grooves and are movably connected to the raw material surrounding frame. A plurality of retaining bolts are respectively inserted into the plurality of connecting bolt holes. A plurality of positioning keys are respectively installed on a plurality of brick blank support plates. The bottom inner side of the device housing is provided with a plurality of key fitting grooves. A plurality of positioning keys are respectively inserted into the device housing through the plurality of key fitting grooves. The raw material surrounding frame is provided with a plurality of brick pressing grooves. A plurality of brick blank support plates are respectively inserted into the plurality of brick pressing grooves.

[0009] It should be noted that, in the above process, the raw material surrounding frame is first inserted into the device housing. Then, multiple retaining bolts are inserted into multiple connecting bolt holes from the outside of the device housing. At this time, multiple reset and demolding springs are compressed by the raw material surrounding frame, and the raw material surrounding frame is fixed and locked. Multiple brick blank support plates are placed into multiple brick pressing slots, and multiple positioning keys on them automatically position the center position, preventing the brick blank support plates from shifting during refractory brick raw material pressing. After the refractory brick raw material is added into the multiple brick pressing slots in the raw material surrounding frame, the pressing hydraulic rod is driven to make the pressing support plate and the raw material surrounding frame come into contact and press against each other. Multiple auxiliary forming keys on the pressing support plate will then extend into... In multiple corresponding brick pressing slots, the refractory brick raw materials are compacted and formed. The anti-adhesion biomimetic lotus leaf pattern on the pressing support plate facilitates the cleaning of residual raw materials and makes maintenance easier. After pressing, the press pulls out the two opposite fixed bolts in sequence, and the raw material surrounding frame is lifted by multiple reset demolding springs. Then, the raw material surrounding frame can be pulled out from the device shell to separate the formed refractory brick raw materials from the raw material surrounding frame. Multiple brick blank pallets remain in the device shell. The refractory brick raw materials can be moved and transported by moving the corresponding brick blank pallets. The shock absorber on the device shell makes the entire equipment operate more smoothly.

[0010] Preferably, the displacement power chamber is provided with a maintenance and inspection port;

[0011] Preferably, the pressing support plate is provided with an anti-adhesion biomimetic lotus leaf pattern;

[0012] Preferably, the pressing support plate is provided with auxiliary forming key;

Compared with existing technologies, this refractory brick forming device features an ingenious two-stage pressure forming structure design, achieving highly efficient and precise pressing of the refractory brick raw material. It completely eliminates the strict dependence on the descent amplitude and speed in traditional forming processes, ensuring that the raw material is perfectly shaped to the maximum extent. Simultaneously, the innovative introduction of an auxiliary forming and quick demolding component further elevates production efficiency and finished product quality to new heights. This component can quickly and smoothly separate the formed and hardened refractory brick raw material from the surrounding frame. This process is both efficient and non-destructive, effectively avoiding any potential damage to the product that traditional demolding methods may cause. Subsequently, these meticulously crafted pressed brick blanks are moved smoothly and orderly to the next production stage via brick blank pallets. Throughout the process, the integrity of the brick blanks is protected to the greatest extent. This series of smooth operations not only significantly improves the automation level of the production line, but also fundamentally reduces the defect rate caused by improper transportation and demolding, thereby greatly improving the yield and overall quality of finished refractory bricks, setting a new benchmark for production efficiency and product quality in the refractory materials industry.

[0022] According to the appendix Figure 1-3It is found that adding the refractory brick forming raw material into the auxiliary forming quick demolding assembly inside the device housing 1 drives the displacement rotor 5 in the displacement power chamber 4 on the main displacement column 2 to rotate, thereby causing the displacement screw 6 to rotate, which in turn drives the downward displacement module 7 to slide downward along the module guide slide 10 on the auxiliary displacement column 3 until the downward displacement module 7 moves to the appropriate position, driving the pressing hydraulic rod 8 to extend, thereby driving the pressing support plate 9 to press against the auxiliary forming quick demolding assembly inside the device housing 1, so that the refractory brick raw material is pressed into shape; first, the raw material surrounding frame 11 is inserted into the device housing 1, and then multiple retaining bolts 15 are inserted into multiple connecting bolt holes 12 from the outside of the device housing 1.
