Description

Technical Field

[0001] This utility model relates to the field of brick processing technology, specifically to a material transfer device for processing magnesia-carbon bricks. Background Technology

[0002] In modern high-temperature industries, especially in the steel smelting industry, magnesia-carbon bricks play an indispensable role as a high-performance refractory material. They are mainly made from magnesia sand and graphite through a specific process. They have advantages such as high refractoriness, good thermal shock resistance and slag erosion resistance. However, a deep analysis of the current magnesia-carbon brick production process reveals that the transfer and conveying device used for processing has obvious shortcomings. In the production process of magnesia-carbon bricks, the transfer and conveying device bears the important responsibility of accurately conveying the raw materials into the mixing box to create conditions for the subsequent uniform mixing process. However, the existing transfer and conveying device faces the dilemma of not being able to achieve uniform feeding according to production needs during actual operation.

[0003] When too much material is fed, it will cause the raw materials to accumulate in the mixing box, making it difficult to mix evenly during the mixing process. This will result in local deviations in the internal composition of the magnesia-carbon bricks. During subsequent high-temperature use, these areas with uneven composition are prone to damage due to performance differences, seriously affecting the overall quality and service life of the magnesia-carbon bricks. Conversely, if too little material is fed, it will not only reduce production efficiency, but may also result in insufficient raw material in the mixing box, making it impossible to form an effective mixing system. This will also cause instability in the composition and performance of the magnesia-carbon bricks, making it difficult to meet the strict requirements of high quality and high stability for magnesia-carbon bricks in high-temperature industries such as steel smelting. Therefore, we propose a transfer and conveying device for processing magnesia-carbon bricks. Utility Model Content

[0004] The purpose of this utility model is to provide a transfer and conveying device for processing magnesium carbon bricks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transfer and conveying device for processing magnesia-carbon bricks, comprising a mixing box, a connecting pipe fixedly installed on the top of the mixing box, a conveying pipe fixedly installed on the top of the connecting pipe, a feeding pipe fixedly installed on the top of the conveying pipe, a funnel fixedly installed on the top of the feeding pipe, a round rod movably installed inside the conveying pipe, and a spiral conveying blade fixedly installed on the surface of the round rod, a drive motor fixedly installed on the side of the conveying pipe, and the output shaft of the drive motor fixedly connected to the round rod, a stirring rod movably installed inside the mixing box, and a spiral stirring blade fixedly installed on the surface of the stirring rod, a connecting plate fixedly installed on the surface of the stirring rod, and a scraper fixedly installed at one end of the connecting plate above the spiral stirring blade, a servo motor fixedly installed on the top of the mixing box, and the output shaft of the servo motor fixedly connected to the stirring rod, and a discharge pipe fixedly installed at the bottom of the mixing box.

[0006] As a further embodiment of this utility model: three sets of support legs are fixedly installed at the bottom of the mixing box, and support leg pads are fixedly installed at the bottom of each of the three sets of support legs.

[0007] As a further embodiment of this utility model: a motor protective cover is provided on the top of the mixing box, a servo motor is provided inside the motor protective cover, and heat dissipation grooves are provided on the surface of the motor protective cover.

[0008] As a further embodiment of this utility model: an L-shaped plate is fixedly installed between the mixing box and the conveying pipe.

[0009] As a further embodiment of this utility model: an observation window is fixedly installed on the surface of the mixing box, and the observation window is made of glass.

[0010] As a further embodiment of this utility model, the inner diameter of the conveying pipe is equal to the outer diameter of the spiral conveying blade.

[0011] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0012] 1. This utility model uses the power of a drive motor to rotate the spiral conveying blades on the surface of a round rod, thereby continuously drawing the raw material inside the funnel into the gap between the spiral conveying blades and conveying it to the top of the connecting pipe and dropping it into the mixing tank. Subsequently, the power of a servo motor causes the spiral stirring blades on the surface of the stirring rod to rotate, thereby mixing the raw material. At the same time, the scraper at one end of the connecting plate scrapes off the raw material adhering to the inner wall of the mixing tank. Finally, the mixed raw material is discharged through the discharge pipe. This device can ensure that various raw materials enter the mixing tank accurately according to a preset ratio, avoiding excessive or insufficient amounts of any one raw material in certain areas, thereby ensuring the consistency and stability of the final product composition, helping to improve the uniformity of the performance of magnesia-carbon bricks, and thus improving the mixing quality.

[0013] 2. This utility model, through the cooperation between the spiral stirring blades and the scraper, enables the scraping off of raw materials adhering to the inner wall of the mixing chamber while mixing the raw materials. This prevents the raw materials from accumulating on the inner wall of the mixing chamber, avoiding abnormal flow of raw materials and poor mixing effect that would lead to uneven mixing. As a result, various raw materials can come into more thorough contact and mix in the mixing chamber, ensuring the uniformity of the magnesia-carbon brick raw material mixing and thus improving product quality.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0021] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see the appendix Figure 1 - Appendix Figure 4 This utility model provides a transfer and conveying device for processing magnesia-carbon bricks, including a mixing box 1, a connecting pipe 2 fixedly installed on the top of the mixing box 1, a conveying pipe 3 fixedly installed on the top of the connecting pipe 2, a feeding pipe 4 fixedly installed on the top of the feeding pipe 3, a funnel 5 fixedly installed on the top of the feeding pipe 4, a round rod 6 movably installed inside the conveying pipe 3, and a spiral conveying blade 7 fixedly installed on the surface of the round rod 6, a drive motor 8 fixedly installed on the side of the conveying pipe 3, and the output shaft of the drive motor 8 fixedly connected to the round rod 6, a stirring rod 9 movably installed inside the mixing box 1, and a spiral stirring blade 11 fixedly installed on the surface of the stirring rod 9, a connecting plate 12 fixedly installed on the surface of the stirring rod 9, and a scraper 13 fixedly installed at one end of the connecting plate 12 above the spiral stirring blade 11, a servo motor 10 fixedly installed on the top of the mixing box 1, and the output shaft of the servo motor 10 fixedly connected to the stirring rod 9, and a discharge pipe 14 fixedly installed at the bottom of the mixing box 1;

[0023] The above solution allows various raw materials to enter the mixing tank accurately according to a preset ratio, avoiding excessive or insufficient amounts of any one raw material in certain areas. This ensures the consistency and stability of the final product composition, helps improve the uniformity of the magnesia-carbon brick performance, and thus improves the mixing quality.

[0024] like Figure 1 As shown, three sets of support legs 18 are fixedly installed at the bottom of the mixing box 1, and support leg pads 19 are fixedly installed at the bottom of each of the three sets of support legs 18.

[0025] The above solution involves fixing three sets of support legs 18 at the bottom of the mixing tank 1, with support leg pads 19 fixedly installed at the bottom of each of the three sets of support legs 18. This disperses the weight of the device and improves its stability during operation.

[0026] like Figure 1 As shown, a motor protective cover 15 is provided on the top of the mixing box 1, a servo motor 10 is provided inside the motor protective cover 15, and a heat dissipation groove 16 is provided on the surface of the motor protective cover 15.

[0027] The above solution is adopted: by setting a motor protective cover 15 on the top of the mixing box 1, and setting a servo motor 10 inside the motor protective cover 15, the servo motor 10 can be protected from damage caused by impact. Heat dissipation grooves 16 are opened on the surface of the motor protective cover 15, thereby improving the heat dissipation effect of the servo motor 10.

[0028] like Figure 1 As shown, an L-shaped plate 20 is fixedly installed between the mixing box 1 and the conveying pipe 3;

[0029] The above solution involves fixing an L-shaped plate 20 between the mixing tank 1 and the conveying pipe 3, thereby strengthening the connection between the mixing tank 1 and the conveying pipe 3 and providing stability.

[0030] like Figure 1 As shown, an observation window 17 is fixedly installed on the surface of the mixing box 1. The observation window 17 is made of glass.

[0031] The above solution is adopted: by fixing an observation window 17 on the surface of the mixing box 1, the internal condition of the mixing box 1 can be viewed. The observation window 17 is made of glass, and the glass has good transparency.

[0032] like Figure 3 As shown, the inner diameter of the conveying pipe 3 is equal to the outer diameter of the screw conveyor blade 7;

[0033] The above solution is adopted: by setting the inner diameter of the conveying pipe 3 to be equal to the outer diameter of the screw conveyor blade 7, leakage can be avoided when transporting raw materials.

[0034] Working principle:

[0035] In use, the operator starts the drive motor 8 via an external switch. The power generated by the drive motor 8 causes the round rod 6 to rotate through its output shaft, thereby driving the spiral conveying blades 7 on the surface of the round rod 6 to rotate. At this time, the operator puts the raw material above the funnel 5. The raw material enters the inside of the conveying pipe 3 through the feeding pipe 4. With the rotation of the spiral conveying blades 7, the raw material enters the gap between the spiral conveying blades 7 and is conveyed to the top of the connecting pipe 2 and falls into the inside of the mixing box 1 from the connecting pipe 2. Then, the operator starts the servo motor 10 via an external switch. The power generated by the servo motor 10 causes the stirring rod 9 to rotate. The spiral stirring blades 11 on the surface of the stirring rod 9 rotate synchronously, thereby mixing the raw material inside the mixing box 1. At the same time, the connecting plate 12 rotates synchronously with the rotation of the stirring rod 9. When the spiral stirring blades 11 are mixing the raw material, the scraper 13 scrapes off the raw material adhering to the inner wall of the mixing box 1. Then, the mixed raw material is discharged through the discharge pipe 14 and collected.
