Technical Field

[0001] The utility model relates to the technical field of mineral powder processing, in particular to a mineral powder rolling and molding device. Background Art

[0002] Mineral powders are fine particles extracted from natural ores through physical or chemical methods and processed through processes such as crushing and grinding. These powders are widely used in a variety of fields, including building materials, ceramics, chemicals, metallurgy, medicine, food, and environmental protection. They are characterized by their high specific surface area, excellent chemical stability, and unique physical properties.

[0003] Compaction is a crucial step in the processing of mineral powders. Compaction further refines powder particles, improving their uniformity and density, thereby enhancing their physical properties and chemical activity. This is crucial for enhancing the quality and performance of the final product. For example, in the building materials industry, compacted mineral powders enhance the strength and durability of materials; in the ceramics industry, it helps improve the finish and density of products.

[0004] Currently, there are a variety of mineral powder compaction methods on the market, including mechanical compaction, airflow milling, and ball milling. Traditional compaction equipment often suffers from high energy consumption and low output, making it difficult to meet the needs of large-scale production. Improper design of the compaction rollers and compaction boxes also leads to uneven distribution of powder during compaction, affecting the final product quality. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art and provides a mineral powder rolling and molding device to solve the problem of uneven distribution in the traditional rolling process, which affects the final quality of the product.

[0006] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a mineral powder rolling and forming device, comprising a frame and a rolling box mounted on the frame; a feed port is reserved on the top of the rolling box, and a hopper is also installed at the feed port; a rolling roller and a cylindrical rolling mesh plate sleeved on the outside of the rolling roller are also installed in the rolling box; the rolling box is respectively provided with a debris discharge port along one side of the rolling roller and a discharge port along the bottom of the cylindrical rolling mesh plate; a debris discharge hopper is installed at the debris discharge port of the rolling box, and a fine material collection hopper is provided at the discharge port.

[0008] Furthermore, a drive shaft connected to the rolling roller is provided on one side of the frame, and a drive wheel is installed on the drive shaft; and a motor drive component for connecting to the drive wheel is also installed on the frame.

[0009] Furthermore, the rolling roller includes a front section of a guide portion that is located below the feed port of the rolling box and is spirally arranged, and a rear section of several rolling ribs that are evenly distributed and adapted to the rolling mesh.

[0010] Furthermore, the rolling roller is arranged to be inclined along the guide portion toward the rolling rib.

[0011] Furthermore, a primary filter tray is arranged above the hopper, and a filter screen is installed in the primary filter tray.

[0012] Furthermore, a hanger extending to above the primary filter disc is also mounted on the frame, and a plurality of hanging ropes for hanging the primary filter disc are installed on the hanger.

[0013] Moreover, the mineral powder rolling and molding device provided by the present invention has at least the following beneficial effects compared with the prior art:

[0014] 1. By adding a primary filter disc and its internal filter, large particles of impurities and foreign matter in the powder are effectively intercepted and removed, significantly improving the purity of the powder entering the compaction box. This improvement directly solves the problem of low powder purity mentioned in the background technology and lays a good foundation for subsequent fine compaction.

[0015] 2. The combination of tilted rollers and cylindrical screens significantly improves powder refinement and uniformity by increasing the contact area and force of the compaction, while also promoting powder flow and distribution. This design not only addresses the unsatisfactory refinement effect found in prior art, but also further enhances product quality and consistency.

[0016] 3. Through rational layout and design, such as the provision of hangers and ropes to facilitate the installation and replacement of the primary filter, and the adoption of a modular design to facilitate the disassembly and repair of various components, the difficulty and cost of equipment maintenance are greatly reduced. This improvement effectively solves the maintenance difficulties mentioned in the background technology and improves the reliability and service life of the equipment.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integrated structures. Those skilled in the art will understand the specific meanings of such terms in this patent based on specific circumstances.

[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, the mineral powder rolling and forming device of the present practical design includes a frame 1 and a rolling box 2 mounted on the frame 1; a feed port is reserved at the top of the rolling box 2, and a hopper 3 is also installed at the feed port; a rolling roller 4 and a cylindrical rolling mesh plate 5 mounted on the outside of the rolling roller 4 are also installed in the rolling box 2; the rolling box 2 has a debris discharge port reserved along one side of the rolling roller 4 and a discharge port reserved along the bottom of the cylindrical rolling mesh plate 5; a debris discharge hopper 6 is installed at the debris discharge port of the rolling box 2, and a fine material collection hopper 7 is provided at its discharge port.

[0025] The working principle of this embodiment is as follows:

[0026] Feeding process:

[0027] The mineral powder is introduced into the top feed port of the crushing box 2 through the hopper 3 .

[0028] Rolling refinement:

[0029] After entering the compacting box 2, the powder is subjected to the rotation of the compacting roller 4. The compacting roller 4 comprises a flow guide 4.1 located below the feed port, and compacting ribs 4.2. The flow guide 4.1, with its spiral design, helps to initially disperse and guide the powder. The compacting ribs 4.2 are evenly distributed around the box and work together with the cylindrical compacting screen 5 mounted on the outside to finely compact the powder, resulting in finer and more evenly distributed particles.

[0030] Impurity separation:

[0031] During the rolling process, impurities in the powder are separated and discharged through the impurity discharge port reserved on one side of the rolling box 2, and fall into the impurity discharge hopper 6 for collection.

[0032] Fine material collection:

[0033] The fine powder after rolling and purification is discharged through the discharge port below the cylindrical rolling mesh plate 5 and finally falls into the fine material collection hopper 7 for subsequent use or processing.

[0034] As an embodiment, a drive shaft 8 connected to the rolling roller 4 is further provided on one side of the frame 1, and a drive wheel 8.1 is installed on the drive shaft 8; the frame 1 is also provided with a motor drive 9 for connecting to the drive wheel 8.1.

[0035] When the motor drive 9 is started, it drives the driving wheel 8.1 to rotate through the transmission device, and then drives the driving shaft 8 to rotate, and finally drives the rolling roller 4 connected thereto to rotate. In this way, the rolling roller 4 can continuously roll the mineral powder entering the rolling box 2.

[0036] As an embodiment, the rolling roller 4 is arranged to be inclined along the guide portion 4.1 toward the rolling rib 4.2.

[0037] This inclined design ensures that during the compaction process, the powder is subjected to a downward force component as it moves along the surface of the compaction roller 4. This force component helps the powder fit more tightly between the compaction roller 4 and the cylindrical compaction screen 5, thereby increasing the contact area and force of compaction, and improving the degree of powder refinement and uniformity. Furthermore, the inclined design promotes the flow and distribution of powder within the compaction box 2, reducing dead corners and accumulation, and further improving compaction efficiency.

[0038] As an embodiment, a primary filter disc 10 is further arranged above the hopper 3 , and a filter screen is installed in the primary filter disc 10 .

[0039] The filter within the primary filter disc 10 performs a preliminary screening and filtration function, effectively intercepting and removing large impurities, foreign matter, or coarse particles that do not meet the particle size requirements. These removed materials remain on the primary filter disc 10 or are collected by its dedicated collection device for processing. The powder that has undergone preliminary filtration and has a more uniform particle size continues to pass through the hopper 3 and enters the crushing box 2 for subsequent fine crushing.

[0040] Specifically, a hanger 1.1 extending to above the primary filter disc 10 is further mounted on the frame 1. A plurality of hanging ropes for hanging the primary filter disc 10 are mounted on the hanger 1.1, which can easily realize the hanging, positioning and fixing of the primary filter disc 10.

Unless otherwise expressly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
