[0002] In the glass manufacturing industry, the precise proportioning and efficient conveying of raw materials are key links to ensure the quality of glass products and production efficiency. With the continuous development and progress of glass production technology, the requirements for the raw material batching system are also increasing day by day.

[0003] Among many conveying equipment, screw conveyors have been widely used in glass raw material batching systems due to their advantages such as compact structure, good sealing performance, and high conveying efficiency. However, traditional screw conveyors still face some challenges in actual use.

[0004] On the one hand, glass raw materials often contain corrosive chemical substances such as soda ash and mirabilite. These substances will cause serious corrosion to the screw blades, shafts, and inner walls of the outer pipes of the conveyor, shortening the service life of the equipment and increasing maintenance costs.

[0005] On the other hand, in order to ensure the quality of glass, extremely high purity requirements are imposed on the raw materials. Some metal elements such as nickel may be introduced during the manufacturing process of traditional screw conveyors. These metal elements may mix into the raw materials, affecting the performance and quality of the glass.

[0006] Therefore, in order to meet the high requirements of the glass production industry for the raw material batching system, it is particularly important to develop a screw conveyor with good corrosion resistance, which can ensure the purity of raw materials and high conveying efficiency.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1-2, the utility model provides a technical solution: a screw conveyor with blades and inner pipes made of nano-ceramic materials, including an outer pipe 1. On one side of the top of the outer pipe 1, there is a feeding and filtering mechanism 2. Inside the outer pipe 1, there is a ceramic inner pipe 3 rotatably connected. On the ceramic inner pipe 3, there are fixed ceramic blades 5. On the inner wall of the outer pipe 1, there is a ceramic lining 4. The ceramic inner pipe 3, the ceramic blades 5, and the ceramic lining 4 are all made of nano-ceramic materials, such as alumina, which can increase hardness, wear resistance, and corrosion resistance. Alumina has good chemical stability and can still remain stable at high temperatures. At the same time, its Rockwell hardness is about 82.2 - 86.4HRA, which is much greater than the hardness of the conveyed materials, thus ensuring its excellent wear resistance. The end of the ceramic inner pipe 3 is connected to a reduction motor through a coupling, which can drive the ceramic inner pipe 3 to rotate, thereby enabling the conveyance of materials. At the tail end of the bottom of the outer pipe 1, there is a discharge port 7. An outlet butterfly valve 8 is installed on the discharge port 7, which can control the discharge port 7 by using the outlet butterfly valve 8. On one side of the bottom of the outer pipe 1, there is an inspection port 6, and the inspection port 6 is connected to the inside of the outer pipe 1, enabling maintenance to be carried out using the inspection port 6.

[0027] In an environment with working conditions of high temperature, high humidity, and certain corrosiveness, the material type is stone dolomite particles with strong abrasiveness, and the average particle size is about 3 millimeters. This screw conveyor has been continuously working for up to 1000 hours. After observing and testing during this period of operation, it is found that the degree of wear of the screw conveyor is extremely small. Only slight scratches appear on the surface of the impeller, and the wear amount is about 0.1 millimeter. In terms of corrosion, almost no obvious corrosion phenomenon is observed. Through professional equipment detection, the hardness of the nano-ceramic material remains stable, and the change in its surface roughness is very small. This indicates that under such harsh working conditions, the nano-ceramic material exhibits excellent wear and corrosion resistance, ensuring the long-term stable operation of the screw conveyor;

[0028] In an environment with working conditions set to have a certain humidity and chemical corrosiveness, the conveyed material type is mirabilite, which is a chemically corrosive raw material. This screw conveyor has been continuously working for 1200 hours. During the operation process of this period, through careful observation and professional detection, it is found that the screw conveyor exhibits excellent anti-corrosion performance when conveying mirabilite materials, and its degree of wear is almost negligible. No obvious corrosion marks appear on the surfaces of the impeller and the conveying pipeline. Particularly important is that the nano-ceramic material completely does not contain nickel metal elements. This characteristic effectively avoids the pollution of mirabilite materials by metal elements, ensuring the purity of the raw materials. In the subsequent process of using mirabilite for glass production, due to the high purity of the raw materials, the quality of the final glass product has been greatly improved. The transparency, uniformity, and various physical properties of the glass have all reached relatively high standards, reducing the production of defective products and waste products.

[0029] Please refer toFigure 3-4 , the feeding and filtering mechanism 2 includes a feeding port 201. A filter box 202 is fixedly connected to the top of the feeding port 201. An opening 203 is provided at the top of the filter box 202. A feeding pipe 204 is provided between one side of the filter box 202 and the feeding port 201. One end of the feeding pipe 204 is communicated with the feeding port 201, and the other end of the feeding pipe 204 penetrates through the filter box 202 and is connected to the diversion groove 214, so that the filtered raw materials inside the filter box 202 can enter the inside of the feeding port 201 through the feeding pipe 204. A turntable 206 is rotatably connected inside the filter box 202. A cylindrical filter screen and a driving motor 207 are respectively fixedly connected to both ends of the turntable 206. A support frame 208 is provided at the top of the cylindrical filter screen. Retaining plates 209 are fixedly connected to both sides of the support frame 208. The retaining plates 209 can intercept the materials, so that the materials can be filtered through the cylindrical filter screen, and the amount of materials directly falling from the outside of the cylindrical filter screen can be reduced. The support frame 208 is fixedly installed at the inner top of the filter box 202. A gap is left between the retaining plate 209 and the cylindrical filter screen, so that the large-particle impurities in the raw materials can roll down along the outer wall of the cylindrical filter screen through the gap. A reciprocating lead screw 210 is rotatably connected inside the support frame 208. A reciprocating motor 211 is fixedly connected to the end of the reciprocating lead screw 210. A reciprocating seat 212 is threadedly connected to the reciprocating lead screw 210. The cross-sectional shape of the reciprocating seat 212 is set to be arc-shaped, and both ends of the reciprocating seat 212 are slidably connected to the retaining plate 209, so that the reciprocating seat 212 can be guided and limited, and it can move along the retaining plate 209. An inclined receiving frame 213 is provided inside the cylindrical filter screen. A vibration motor is fixedly connected to the end of the inclined receiving frame 213. A diversion groove 214 is fixedly connected to the end of the inclined receiving frame 213. The inclined receiving frame 213 is fixedly connected to the inner wall of the filter box 202. The diversion groove 214 is inclined and arranged on one side of the inclined receiving frame 213, so that the inclined receiving frame 213 can use the inclined diversion groove 214 to divert the materials. A impurity storage tray 205 is provided at the bottom of the cylindrical filter screen, which can receive the impurities and is detachably connected to the filter box 202, which is convenient for centralized treatment of the impurities.

[0030] During operation, the materials enter the inside of the filter box 202 through the opening 203 and are intercepted by the retaining plate 209 on the top of the cylindrical filter screen. The reciprocating motor 211 drives the reciprocating lead screw 210 to rotate, and the rotation of the reciprocating lead screw 210 drives the reciprocating seat 212 to reciprocate, flattening the materials, promoting the filtering effect, and the driving motor 207 drives the cylindrical filter screen to rotate, so that relative rotation occurs between the materials and the cylindrical filter screen to ensure the filtering effect. The filtered materials pass through the cylindrical filter screen and fall onto the inclined receiving frame 213. The vibration motor generates vibration to shake the materials into the diversion groove 214, and then enter the feeding pipe 204 through the diversion groove 214. The feeding pipe 204 feeds the materials into the feeding port 201, so that large-particle impurities can be prevented from entering, effectively improving the feeding effect;

[0031] The ceramic inner tube 3, the ceramic blades 5, and the ceramic lining 4 are all made of nano-ceramic materials, such as alumina, which can increase hardness, wear resistance, and corrosion resistance. Alumina has good chemical stability and can remain stable at high temperatures. At the same time, its Rockwell hardness is about 82.2 - 86.4 HRA, which is much greater than the hardness of the conveyed material, thus ensuring its excellent wear resistance.
