Description

Technical Field

[0001] The utility model relates to the technical field of ceramics, in particular to a bottom flow port forming die for a large-sized ceramic piece. Background Art

[0002] As an efficient separation and classification equipment, the cyclone plays an important role in many fields such as mining, petrochemicals, and environmental protection. Its unique design makes it have extremely high precision in the sorting process. At the same time, since there are no moving parts, the maintenance cost is low, and it can handle a large amount of materials, so it has shown significant classification effects and economic benefits in practical applications. For this reason, the cyclone has gradually become the main equipment in the heavy medium beneficiation process, providing strong support for the rapid development of the industry.

[0003] However, with the continuous advancement of technology and the growing industrial demand, the challenges faced by cyclones are also increasing. In particular, the continuous increase in feed size, pressure and speed has put forward higher requirements on the main components of the cyclone. Among these components, the underflow port is an important part of the cyclone, and its performance directly affects the separation effect and operation stability of the entire equipment.

[0004] The underflow port is located at the bottom of the cyclone and is an important channel for material discharge. Due to its special status and function, the underflow port has strict requirements on materials and manufacturing processes. At present, there are relatively few cases in the market where ceramic materials are used to prepare easily worn parts such as the underflow port of the cyclone. This is mainly because the dimensional accuracy requirements of the underflow port are high and the preparation is difficult. Traditional ceramic forming processes often fail to meet production requirements when preparing large-sized special-shaped ceramic parts, resulting in unstable product quality and low production efficiency.

[0005] To solve this problem, the preparation of such components is generally done by splicing ceramic arc plates. However, the limitations of this method are obvious. Not only can it not fully meet the shape and size requirements of the underflow port, but it is also easy to generate stress concentration during the splicing process, affecting the strength and wear resistance of the components.

[0006] Therefore, it is urgent to develop a new bottom flow port molding mold for large-size ceramic parts to effectively solve the problems in the molding process, improve the product performance degradation caused by molding problems, and improve product quality to meet production requirements.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0026] Example 1

[0027] This embodiment provides a large-size ceramic bottom flow port forming mold, such as Figure 1-3 As shown, it includes a mold frame 1, a lower gasket 2 and an inner liner 3. The mold frame 1 and the inner liner 3 are both truncated cone-shaped and the upper surface radius is larger than the lower surface radius. The mold frame 1 is a hollow structure with upper and lower openings, while the inner liner 3 is a solid structure. The lower gasket 2 is placed at the bottom of the mold frame 1 and the top extends into the mold frame 1. A sealing ring 5 (such as Figure 4 As shown), the two are closely fitted to ensure the sealing of the mold. The liner 3 is placed in the mold frame 1 and as shown Figure 3 As shown, a handle 4 is provided on the top, and a protrusion 301 is provided on the bottom of the lining 3. Figure 4 As shown, a groove 201 is provided at the center of the lower gasket 2, a protrusion 301 is placed in the groove 201 and matches the groove 201, and a sealing ring 5 is provided between the protrusion 301 and the groove 201. Figure 2 As shown, there is a gap between the liner 3 and the mold frame 1, and the gap forms a pouring cavity 6, and the ceramic slurry at the bottom flow outlet of the ceramic part is poured into the pouring cavity 6.

[0028] When using the mold of this embodiment to form a large-sized ceramic bottom flow outlet, the lower gasket 2 is placed at the bottom of the mold frame 1, and the two are assembled. Then, the handle 4 is held, and the protrusion 301 at the bottom of the liner 3 is aligned with the groove 201 on the lower gasket 2, and the liner 3 is placed in the mold frame 1 to complete the assembly of the entire mold. Subsequently, the ceramic slurry is poured into the pouring cavity 6. After the pouring is completed, it is left to solidify for a period of time. After the liner 3 is taken out, the mold frame 1 is turned upside down, and the lower gasket 2 is removed to complete the demolding of the ceramic blank. After demolding, the ceramic blank is dried and sintered to obtain a large-sized ceramic bottom flow outlet.

[0029] The large-size ceramic bottom outlet forming mold of this embodiment has a detachable lower gasket 2 and a handle 4 on the inner liner 3, which makes the mold easy to disassemble and demould, and is convenient to clean without leaving dead corners, which is more conducive to maintaining the integrity of the ceramic blank. At the same time, the sealing ring 5 between the lower gasket 2 and the mold frame 1 and the inner liner 3 can enhance the sealing of the mold and effectively prevent the leakage of ceramic slurry during the grouting and curing process.

[0030] Example 2

[0031] On the basis of Example 1, Figure 1-2 As shown, a handle 4 is provided on the mold frame 1. When demoulding, the mold frame 1 can be turned upside down by holding the handle 4, which makes the operation more convenient.

[0032] Example 3

[0033] On the basis of Example 1, scale lines are arranged on the inner wall of the mold frame 1, and the pouring amount of the ceramic slurry can be controlled according to the scale lines to improve the work efficiency.

[0034] Example 4

[0035] On the basis of Example 1, Figure 5 As shown, the mold of this embodiment also includes a circular cover 7. After the ceramic slurry is poured, the cover 7 is placed on the top of the ceramic slurry to allow the slurry to solidify evenly in a relatively closed environment, thereby avoiding the problem of uneven shrinkage and deformation of the ceramic body. The cover 7 is removed after the slurry is solidified and formed.
