Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a wet grinding equipment for green spinel composite materials used in refining furnaces. Background Technology

[0002] Grinding equipment is a type of industrial device widely used in chemical, mineral processing, new materials, pharmaceutical, and food industries. Its core function is to crush and refine solid materials using mechanical force, reducing particle size and increasing specific surface area to achieve specific physical or chemical performance requirements. Its basic working principle utilizes the collision, shearing, and compression between grinding media (such as balls, rods, or grinding beads) and the processed material to reduce particle size to the micrometer or even nanometer level. Depending on the process requirements, grinding equipment has developed into various structural forms, such as ball mills, vibratory mills, stirred mills, and sand mills, and is an indispensable key piece of equipment in modern industrial production.

[0003] Based on whether a liquid medium is used in the grinding process, grinding processes can be mainly divided into two categories: dry grinding and wet grinding. Dry grinding refers to grinding materials in a completely dry state, where the materials are mainly transported and dispersed inside the equipment by airflow or mechanical force. This method is relatively simple and does not require subsequent dehydration and drying, but its grinding efficiency and fineness are usually limited, and it is prone to dust pollution and heat accumulation problems. In contrast, wet grinding is carried out in the presence of a liquid medium. The liquid medium acts as a carrier for the materials, and is fully mixed with the grinding media and materials to form a slurry-like fluid.

[0004] Compared to dry grinding, wet grinding exhibits several significant advantages. Firstly, in terms of grinding efficiency and fineness, the presence of a liquid medium provides excellent grinding aid and dispersion, effectively reducing the surface energy of the material and preventing the re-agglomeration of fine particles, thus making it easier to obtain products with uniform distribution and finer particle size. Secondly, regarding energy consumption and thermal management, the liquid medium effectively absorbs and removes the large amount of heat generated during the grinding process, preventing equipment damage. In terms of environmental protection and operability, the wet process completely avoids dust pollution, resulting in a cleaner and safer working environment, and also makes material conveying and discharging more convenient.

[0005] Existing wet grinding equipment typically uses a single grinding method and cannot perform multi-stage grinding simultaneously, resulting in insufficient grinding efficiency. For example, when grinding green spinel composite materials for refining furnaces, the high hardness and good wear resistance of these materials mean that a single grinding method is not efficient enough. Therefore, a more efficient wet grinding equipment is needed. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a wet grinding equipment for green spinel composite materials for refining furnaces.

[0007] The technical solution of this utility model is: a wet grinding equipment for green spinel composite materials for refining furnaces, including a grinding chamber, a feed trough fixed above the grinding chamber, an upper grinding disc rotatably connected to the middle of the grinding chamber via a support ring, a material leakage hole in the middle of the upper grinding disc, a gear ring fixed to the outer wall of the upper grinding disc, a notch on one side of the grinding chamber, a grinding motor for driving the upper grinding disc to rotate fixed to the outer wall of the grinding chamber, a gear meshing with the gear ring fixed to the output shaft of the grinding motor, a lower grinding disc below the upper grinding disc, the bottom of the lower grinding disc fixed to the bottom of the grinding chamber via a hydraulic rod, a discharge trough fixed to the inner wall of the grinding chamber on the outer side of the lower grinding disc, a discharge port connected to one side of the discharge trough, a filter cylinder below the discharge port, a nozzle on the inner wall above the grinding chamber, and a water pipe connected to the outer end of the nozzle.

[0008] Furthermore, a rotating disk is rotatably connected to the top of the grinding chamber, and a grinding rod is rotatably connected to the bottom of the rotating disk. The grinding rod is located inside the material leakage hole, and the lower end of the grinding rod abuts against the upper end of the lower grinding disk. A second grinding motor for driving the rotating disk to rotate is fixed to the top of the grinding chamber.

[0009] Explanation: By pressing the grinding rod against the inner wall of the discharge hole, the green spinel fragments are further broken into coarser particles, which prepares for the second stage of grinding and can effectively improve the efficiency of the second stage of grinding.

[0010] Furthermore, the lower surface of the upper grinding disc and the upper surface of the lower grinding disc are provided with a plurality of grinding grooves extending from the inside out.

[0011] Note: The grinding tank increases the cutting force on the green spinel, thereby further improving the grinding efficiency. The depth of the grinding tank can adjust the particle size of the output.

[0012] Furthermore, a filter cloth is snapped onto the top of the filter media cylinder, a filter media support is provided below the filter media cylinder, and a filtrate tank is provided below the filter media support.

[0013] Description: The green spinel composite material powder is filtered through the filter cloth to remove moisture from the green spinel powder, achieving solid-liquid separation. This structure facilitates the transfer of the filter media cartridge.

[0014] Furthermore, a baffle ring is provided above the interior of the grinding chamber, with the upper end of the baffle ring fixed to the inner wall of the grinding chamber and the lower end of the baffle ring located inside the material leakage hole.

[0015] Note: The retaining ring effectively prevents green spinel chips and splashing water droplets from entering from above the upper grinding disc, ensuring that the rotating components between the upper grinding disc and the support ring are not affected by chips.

[0016] The beneficial effects of this utility model are: This invention uses a grinding rod to press against the inner wall of the discharge hole to crush coarser fragments into coarser particles, completing the first stage of grinding. The coarser particles then enter the gap between the upper and lower grinding discs through the discharge hole for the second stage of grinding, forming smaller particles that flow into the discharge trough under the flushing of water. Finally, the particles are filtered through a filter cloth to obtain wet powder. This invention's multi-stage simultaneous grinding effectively improves grinding efficiency.

[0023] A filter cloth 81 is attached to the top of the filter media cylinder 8, a filter media support 82 is attached to the bottom of the filter media cylinder 8, and a filtrate tank 83 is attached to the bottom of the filter media support 82.

[0024] The green spinel composite material powder is filtered through filter cloth 81 to remove moisture from the green spinel powder and achieve solid-liquid separation. This structure facilitates the transfer of filter media 8.

[0025] Example 2: The difference between this embodiment and embodiment 1 is that, in this embodiment, a rotating disk 9 is rotatably connected to the top of the grinding chamber 1, and a grinding rod 91 is rotatably connected to the bottom of the rotating disk 9. The grinding rod 91 is located inside the material leakage hole 41, and the lower end of the grinding rod 91 abuts against the upper end of the lower grinding disk 5. A second grinding motor 92 for driving the rotating disk 9 to rotate is fixed to the top of the grinding chamber 1.

[0026] Compared to Example 1, this embodiment further crushes the green spinel fragments into coarser particles by pressing the grinding rod 91 against the inner wall of the discharge hole 41, thus preparing for the second stage of grinding and effectively improving the efficiency of the second stage of grinding.

[0027] Example 3: The difference between this embodiment and embodiment 2 is that, in this embodiment, as... Figure 3 , Figure 4 As shown, the lower surface of the upper grinding disc 4 and the upper surface of the lower grinding disc 5 are provided with a number of grinding grooves 52 extending from the inside out.

[0028] Compared to Example 2, this embodiment increases the cutting force on the green spinel through the grinding tank 52, thereby further improving the grinding efficiency. The depth of the grinding tank 52 can adjust the particle size of the output.

[0029] Example 4: The difference between this embodiment and embodiment 3 is that in this embodiment, a baffle ring 12 is provided above the inside of the grinding chamber 1. The upper end of the baffle ring 12 is fixed to the inner wall of the grinding chamber 1, and the lower end of the baffle ring 12 is located in the material leakage hole 41.

[0030] Compared to Embodiment 3, in this embodiment, the retaining ring 12 can effectively prevent green spinel dust and splashing water droplets from entering from above the upper grinding disc 4 and falling onto the support ring 3, ensuring that the rotating assembly between the upper grinding disc 4 and the support ring 3 is not affected by the dust.

[0031] The working method of Embodiment 4 above includes the following steps: S1. The fragments of green spinel composite material are fed into the grinding chamber 1 from the feed trough 2. The fragments fall into the inner wall of the discharge hole 41. The green spinel composite material fragments are crushed into coarser particles by the extrusion of the grinding rod 91 against the inner wall of the discharge hole 41, thus completing the first stage. S2. Coarser particles enter the gap between the upper grinding disc 4 and the lower grinding disc 5 through the discharge hole 41 for the second stage of grinding. The grinding groove 52 increases the cutting force on the green spinel. The depth of the grinding groove 52 can adjust the particle size of the output, forming smaller particles that flow into the discharge groove 6 under the flushing of water, and then flow into the filter cylinder from the discharge port 7. After being filtered by the filter cloth, wet powder is obtained.

[0032] In the above embodiments, both the first grinding motor 44 and the second grinding motor 92 are commercially available products. As long as they can achieve the function of this utility model, they are acceptable. Those skilled in the art can choose to use them based on common sense, and no special limitations are made here.
