Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, specifically to a coarse crushing device for removing iron from ceramic raw materials. Background Technology

[0002] The production of ceramic products places extremely high demands on the quality of raw materials, especially in the pretreatment stage. The particle size uniformity, purity, and compositional stability of the raw materials directly affect subsequent molding, drying, and sintering processes. Therefore, ceramic raw materials typically undergo crushing and impurity removal before being fed into the furnace to ensure the uniformity and plasticity of the materials.

[0003] Currently, most ceramic raw material crushing equipment on the market is a single-function crusher, which mainly uses mechanical structures such as impact hammers, crushing blades, or impellers to impact and crush large pieces of raw materials. However, these devices generally suffer from the following technical defects:

[0004] Poor particle size control: Conventional crushing equipment can usually only achieve coarse crushing, resulting in uneven particle size distribution. This makes it difficult to meet the "controllable particle size" requirement of ceramic raw materials, and the presence of some large particles affects the uniformity of mixing and the firing effect.

[0005] Impurities, especially iron, are difficult to remove effectively: Ceramic raw materials often contain magnetic impurities such as iron nails, iron sand, and metal powder. If not removed in time, these impurities can easily cause defects in the finished product, cracking during firing, or even contamination of the kiln furniture. However, most existing crushing equipment does not have an iron removal function or requires the use of an external magnetic separator, which complicates the process and increases costs.

[0006] The magnetic separation system is disconnected from the crushing system: Currently, some iron removal equipment is designed independently, which leads to problems such as material transfer, blockage, and mixing between the magnetic separation system and the crushing system. In addition, the operating efficiency is low and the degree of automation is low, which is not conducive to continuous industrial operation.

[0007] In view of this, we have studied and improved the existing problems and provided a ceramic raw material iron removal and coarse crushing device to solve the current problems. The aim of this technology is to solve the problems and improve its practical value. Summary of the Invention

[0008] This utility model aims to solve the technical problems existing in the current ceramic raw material crushing equipment, such as unsatisfactory crushing effect, low impurity separation efficiency, complex structure of iron removal device, and low integration. It provides a ceramic raw material iron removal coarse crushing device with reasonable structure, stable operation, and high degree of integration of crushing and iron removal.

[0009] This invention innovatively integrates a crushing module and a high-frequency magnetic separation module into the same device, achieving efficient coarse crushing of ceramic raw materials and simultaneous separation of iron impurities. This improves the purity of ceramic clay, enhances production efficiency and product quality, and is suitable for continuous industrial applications in the pretreatment process of ceramic raw materials.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A coarse crushing device for removing iron from ceramic raw materials, comprising:

[0012] Crushing chamber: It is equipped with a feed hopper at the top and a sorting hopper at the bottom. An inspection door is located at the front of the crushing chamber for easy maintenance. The bottom of the sorting hopper has an output assembly for discharging the processed ceramic raw materials.

[0013] Crushing assembly: Located inside the crushing chamber, including the main shaft, drive motor, crushing impeller, and stationary ring impeller.

[0014] One end of the main shaft passes through the crushing chamber and is fitted with the crushing wheel, while the other end is connected to the drive motor. The crushing wheel is equipped with multiple impact plates in the circumferential direction for impacting and crushing raw materials. The fixed ring wheel is installed inside the inspection door, and its surface is equipped with fixed bars, which form a shearing fit with the crushing wheel to improve the crushing strength.

[0015] Magnetic separation assembly: installed inside the sorting hopper, including:

[0016] Linear vibrator: Fixed to the outer shell of the crushing chamber, used to drive the flow guide box to achieve high-frequency vibration;

[0017] The guide box is installed inside the sorting hopper to receive the crushed raw materials and guide them into the magnetic separation area.

[0018] Multiple magnetic rods: arranged alternately on the inner wall of the flow guide box, used to adsorb magnetic impurities such as iron filings mixed in the ceramic raw materials.

[0019] The linear vibrator can employ an excitation box structure with an internal electromagnetic coil. This coil excites a permanent magnet on the floating block to generate magnetic vibration, enabling high-frequency movement of the floating block. The floating block is connected to the excitation box via an elastic element and fixedly connected to the guide box, thereby driving the guide box to vibrate as a whole. This causes the ceramic raw material to be fully dispersed under the action of the magnetic rod, completing the iron removal process.

[0020] The output component is preferably an electric auger structure, which can stably output the iron-removed ceramic raw materials, facilitating subsequent processing or transportation.

[0021] This utility model, through innovative structural integration and functional optimization design, achieves the following technical effects:

[0022] Excellent crushing effect: The shearing crushing combination of the crushing impeller and the fixed ring impeller, as well as the high-speed rotating impact crusher, can efficiently process block raw materials and improve the uniformity and efficiency of raw material crushing.

[0023] High iron removal efficiency: The high-frequency vibration magnetic separation component and the flow-guided raw material dispersion structure enhance the contact time and area between the raw material and the magnetic rod, significantly improving the ability to capture magnetic impurities.

[0024] Compact and integrated structure: The coarse crushing and magnetic separation system are integrated into one unit, which takes up little space, is easy to maintain, and is suitable for continuous production line integration;

[0025] Stable and reliable operation: The modular design makes it easy to maintain and replace key components. In particular, the crushing and magnetic separation components work together smoothly with a low failure rate.

[0026] It has a wide range of applications: it is not only suitable for the pretreatment of ceramic raw materials, but also for the preprocessing of other non-metallic mineral raw materials containing iron impurities.

[0027] In summary, the ceramic raw material iron removal and coarse crushing device provided by this utility model can not only achieve efficient coarse crushing and iron removal of ceramic raw materials, but also has many advantages such as optimized structure, stable performance, and thorough impurity removal. It has good industrial practical value and promotion prospects. Attached Figure Description

[0037] To better understand the technical solution of this utility model, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and do not limit the scope of protection of this utility model.

[0038] like Figures 1 to 5 As shown, this utility model provides a coarse crushing device for removing iron from ceramic raw materials, which mainly includes: a crushing chamber 100, a crushing component 200, a magnetic separation component 300, and several auxiliary structures.

[0039] The crushing chamber 100 is a frame-type enclosed structure. It has a feed hopper 110 at the top for feeding ceramic raw materials, a sorting hopper 120 at the bottom for holding the crushed material, and an output assembly 130 at the bottom for discharging the processed ceramic raw materials. The front of the crushing chamber 100 has an openable inspection door 140 for easy maintenance and replacement of the internal crushing components.

[0040] The crushing assembly 200 is disposed inside the crushing chamber 100, and specifically includes:

[0041] The main shaft 210 has one end rotatably mounted on the inner wall of the crushing chamber 100 via a bearing assembly, and the other end is connected to the externally installed drive motor 220.

[0042] The crushing impeller 230 is fixedly installed on the main shaft 210, and its outer edge is provided with several impact plates evenly distributed along the circumference, which are used to perform high-intensity impact and coarse crushing on the falling ceramic raw materials.

[0043] The fixed ring wheel 240 is fixedly installed inside the inspection door 140. Its inner surface is provided with multiple fixed bars, which cooperate with the crushing wheel 230 to form an effective crushing chamber to improve crushing efficiency.

[0044] After the drive motor 220 starts, it drives the main shaft 210 to rotate at high speed, which in turn drives the crushing wheel 230 to rotate, and performs shearing and impact crushing on the falling ceramic raw materials between the wheel 230 and the fixed ring wheel 240.

[0045] The magnetic separator 300 is installed inside the sorting hopper 120 and includes:

[0046] Linear vibrator 310: Fixedly installed on the surface of the crushing chamber 100, used to drive the flow guide box 320 to vibrate at high frequency;

[0047] Flow guide box 320: It is installed inside the sorting hopper 120 to receive the crushed ceramic raw materials and complete the iron removal operation through high-frequency vibration in conjunction with the magnetic rod;

[0048] Magnetic rods 330: Several magnetic rods are arranged alternately inside the flow guide box 320 to adsorb iron filings or magnetic impurities in the raw material. The magnetic rods 330 can be permanent magnet structures or energized electromagnetic structures. Specifically, the magnetic rods 330 are rod-shaped permanent magnets or electromagnetic components, and are arranged alternately inside the flow guide box 320 to enhance the magnetic separation coverage and iron removal efficiency.

[0049] During operation, the linear vibrator 310 drives the guide box 320 to vibrate at high frequency horizontally or vertically, causing the crushed raw material to shake and slide rapidly in the guide box. Magnetic impurities in the raw material are effectively adsorbed when passing above the magnetic rod 330, thereby achieving the effect of iron removal and purification.

[0050] The linear vibrator 310 further includes:

[0051] Excitation box 311: It is equipped with an electromagnetic coil for exciting vibration;

[0052] Floating block 312: Movably installed inside the excitation box 311, suspended on both sides by elastic elements 313 to provide restoring force; a permanent magnet 314 is installed on the floating block 312, which drives the floating block 312 to move back and forth at high frequency under the action of the changing magnetic field generated by the electromagnetic coil being energized. The vibration drive of the current guide box 320 is realized through the rigid connection between the floating block 312 and the current guide box 320.

[0053] The output component 130 is located at the bottom of the sorting hopper 120, preferably an electric auger structure, whose spiral blades can rotate under the drive of a motor to transport the ceramic raw materials after iron removal to the outside of the equipment for subsequent processing or storage.
