Description

Technical Field

[0001] This utility model relates to the field of material conveying, specifically a graphitized high-temperature coke conveying and retrieving mechanism. Background Technology

[0002] In the field of carbon graphitization coke conveying, the conveying and cooling of high-temperature coke is a crucial industrial process involving various technologies and equipment to ensure both safety and efficiency during coke collection and distribution. However, existing high-temperature coke conveying equipment suffers from several problems: First, the conveying equipment often lacks the ability to cool the high-temperature coke during transport, requiring the coke to be transported only after its temperature drops below 600°C, resulting in long waiting times. Second, the excessively high coke temperature makes the conveying inlet highly susceptible to damage. Furthermore, due to the low thermal conductivity of the material, the internal temperature of the coke covered by the graphitization furnace exceeds 1000°C, making it impossible for existing conveying equipment to perform prolonged air lifting for coke collection. Additionally, existing overhead crane coke collection technology suffers from a lack of rapid installation and disassembly of the material conveying equipment, resulting in poor flexibility and extended installation times.

[0003] Therefore, there is an urgent need for a new high-temperature conveying and material handling mechanism that can handle materials with low thermal conductivity and internal material temperatures exceeding 1000 degrees Celsius. Summary of the Invention

[0004] The purpose of this invention is to provide a graphitized high-temperature coke conveying and lifting mechanism. By installing the mechanism at the air conveying pipe inlet and using a crane to drive the entire mechanism to move back and forth, it can realize long-distance transportation and lifting of high-temperature powdery materials. By utilizing the structure of a fixed seat, cooling system, curved plow and movable locking device, it solves the problem in the prior art that the material has a low thermal conductivity and cannot be conveyed for a long time when the internal temperature exceeds 1000 degrees Celsius. The water cooling circulation of the cooling system can quickly cool down the entire mechanism, enabling the mechanism to operate stably in a high-temperature environment for a long time.

[0005] To solve the above-mentioned technical problems, this utility model provides a graphitized high-temperature coke conveying and feeding mechanism, including a fixed base, a cooling system, curved plows, and a movable locking device. The fixed base includes an annular base and a mounting platform integrally formed from top to bottom. The annular base has a first cooling chamber, and its outer side wall is respectively provided with an inlet pipe and an outlet pipe communicating with the first cooling chamber. The inlet pipe and the outlet pipe are respectively connected to the cooling system through external pipes. There are two mounting platforms symmetrically distributed below the annular base. Each mounting platform has a second cooling chamber communicating with the first cooling chamber. There are two curved plows, which are respectively installed on the inner side wall of each mounting platform. The distance between the front ends of the two curved plows is greater than the distance between their rear ends. An air conveying pipe passes through the annular base, extends between the two curved plows, and is fixed by the movable locking device for sucking up coke.

[0006] Furthermore, the cooling system includes a circulating water pump, a circulating water tank, and a heat exchanger connected in sequence by pipes. The output end of the circulating water pump is connected to the inlet pipe via an external pipe, and the outlet pipe is connected to the inlet end of the heat exchanger via an external pipe.

[0007] Furthermore, the movable locking device includes several retaining seats and fastening bolts. The retaining seats hug the outside of the air conveying pipe, and their lower parts extend between the annular seat and the air conveying pipe. The lower outer side wall of the retaining seats is provided with an inclined surface that fits the position of the annular seat and the air conveying pipe. After fitting, the retaining seats and the annular seat are locked together by the fastening bolts.

[0008] Furthermore, each of the card holders includes a connecting plate and a snap-fit ​​plate integrally formed from top to bottom. The connecting plate is arc-shaped and has two fastening holes. The snap-fit ​​plate has a beveled surface on its lower outer side wall. The fastening bolt passes through the corresponding fastening hole and is threadedly connected to the annular seat. The snap-fit ​​plate has a triangular cross-section and is wider at the top and narrower at the bottom.

[0009] Furthermore, the included angle formed between the inner walls of the two mounting platforms is 30°.

[0010] Furthermore, the surfaces of both curved plows are coated with a high-temperature resistant and wear-resistant coating.

[0011] Furthermore, the high-temperature resistant and wear-resistant coating is a ceramic coating.

[0012] Furthermore, the curved plow is fixed to the mounting platform by a number of screws.

[0013] The beneficial effects of this utility model are: 1. By installing the graphitized high-temperature coke conveying and lifting mechanism of this utility model at the air conveying pipe inlet, and using the operation of the overhead crane to drive the entire mechanism to move back and forth, long-distance transportation and lifting of high-temperature powdery materials can be realized. Utilizing the structure of the fixed seat, cooling system, curved plow and movable locking device, it can adapt to the material handling needs of various bulk materials, improve material handling efficiency, achieve rapid installation, and quickly remove the heat generated by the structure. It solves the problem in the prior art that the material has a low thermal conductivity and cannot be conveyed for a long time when the internal temperature exceeds 1000 degrees Celsius, thereby improving the overall efficiency and safety of the material conveying system. Specifically, the material turned over by the curved plow is collected to the air conveying pipe, and the material is lifted and conveyed by air. This enables efficient material collection of bulk materials, breaking through the limitation of traditional material collection devices that can only replace the coke extraction pipe. The heat of the material can be conducted to the fixed seat through the curved plow. The design of the cooling chamber 1, cooling chamber 2 and cooling system in the fixed seat can quickly remove the heat, improve the efficiency of material conveying, and effectively solve the problem of lack of cooling at the coke extraction pipe in the material conveying equipment in the existing technology. The water cooling circulation of the cooling system can quickly cool down the entire mechanism, enabling the mechanism to operate stably in a high-temperature environment for a long time.

Detailed Implementation

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In one specific embodiment of this utility model, such as Figure 1-9As shown, a graphitized high-temperature coke conveying and feeding mechanism includes a fixed base 1, a cooling system, curved plows 2, and a movable locking device 3. The fixed base 1 includes an annular base 11 and a mounting platform 12 integrally formed from top to bottom. The annular base 11 is provided with a cooling chamber 111 and its outer wall is provided with an inlet pipe 4 and an outlet pipe 5 communicating with the cooling chamber 111. The inlet pipe 4 and the outlet pipe 5 are respectively connected to the cooling system through external pipes. There are two mounting platforms 12 symmetrically distributed below the annular base 11. Each mounting platform 12 is provided with a cooling chamber 121 communicating with the cooling chamber 111. There are two curved plows 2 and they are respectively installed on the inner side wall of each mounting platform 12. The distance between the front ends of the two curved plows 2 is greater than the distance between the rear ends. An air conveying pipe 100 passes through the annular base 11 and extends between the two curved plows 2 and is fixed by the movable locking device 3 for sucking up coke.

[0019] By installing the graphitized high-temperature coke conveying and feeding mechanism of this utility model at the air conveying pipe inlet, and using the operation of an overhead crane to drive the entire mechanism to move back and forth, long-distance transportation and lifting of high-temperature powdery materials can be achieved. Specifically, the material turned up by the curved plow is collected to the air conveying pipe inlet, and the material is lifted and conveyed by air conveying. This can achieve efficient feeding of bulk materials, breaking through the limitation of traditional feeding devices that can only replace the coke feeding pipe. Moreover, the heat of the material can be conducted to the fixed seat through the curved plow. With the design of cooling chamber one, cooling chamber two and cooling system in the fixed seat, the heat is quickly removed, effectively solving the problem of lack of cooling at the coke feeding pipe inlet in the material conveying equipment in the prior art. The water cooling circulation of the cooling system is used to quickly cool down the entire mechanism, which can achieve long-term stable operation of the mechanism in a high-temperature environment.

[0020] like Figure 1 As shown, the cooling system includes a circulating water pump 6, a circulating water tank 7, and a heat exchanger 8 connected in sequence by pipes. The output end of the circulating water pump 6 is connected to the inlet pipe 4 through an external pipe, and the outlet pipe 5 is connected to the inlet end of the heat exchanger 8 through an external pipe. Cooling water enters from the inlet pipe 14, and the heat of the material is conducted to the fixed seat 1 through the curved plow 2. The heat is exchanged with the cooling water using the first cooling chamber 111 and the second cooling chamber 121 in the fixed seat 1, and then carried out by the outlet pipe 5. Through the design of the cooling system, the cooling water can be circulated in the fixed seat 1, realizing the function of rapid cooling of the entire mechanism, achieving closed-loop cooling of the entire mechanism, and enabling the mechanism to operate stably in a high-temperature environment for a long time.

[0021] like Figure 6-7As shown, the movable locking device 3 includes several retaining seats 31 and fastening bolts 32. The retaining seats 31 hug the outside of the air conveying pipe 100, and their lower parts extend between the annular seat 11 and the air conveying pipe 100. The lower outer wall of the retaining seats 31 is provided with an inclined surface 312 for tightly engaging the annular seat 11 and the air conveying pipe 100. After being tightly engaged, the retaining seats 31 and the annular seat 11 are locked together by the fastening bolts 32. Through the design of the movable locking device, the air conveying pipe can be quickly fixed and disassembled, making installation convenient.

[0022] Specifically, each card holder 31 includes a connecting plate 301 and a snap-fit ​​plate 302 integrally formed from top to bottom. The connecting plate 301 is arc-shaped and has two fastening holes 311. The snap-fit ​​plate 302 has a bevel 312 on its lower outer side wall. The fastening bolt 32 passes through the corresponding fastening hole 311 and is threaded to the annular seat 11. The cross-section of the snap-fit ​​plate 302 is triangular and is wider at the top and narrower at the bottom. The bevel structure design of the snap-fit ​​plate makes the card holder fit tighter and tighter into the annular seat, better clamping the air conveying pipe to the outside to fix the air conveying pipe.

[0023] Specifically, the surfaces of both curved plows 2 are coated with a high-temperature and wear-resistant coating. The design of the high-temperature and wear-resistant ceramic coating significantly improves the oxidation resistance of the curved plow 2 material, extends the service life of the curved plow 2, and solves the problem of easy damage to the plow in the prior art. In this embodiment, the high-temperature and wear-resistant coating is a ceramic coating. Of course, other high-temperature and wear-resistant coatings can also be used in other embodiments.

[0024] Specifically, in this embodiment, the curved plow 2 is fixed to the mounting platform 12 by several screws 9; this design facilitates the installation and disassembly of the curved plow, enabling quick replacement of different curved plows; for example... Figure 8-9 In this embodiment, the curved plow adopts a curved structure, and the whole is a triangular structure with a smaller front and a larger back, which can realize the turning function of metallurgical coke.

[0025] In this embodiment, the included angle formed between the inner walls of the two mounting platforms 12 is 30°, which can realize the function of collecting coke into the air conveying pipe. At the same time, the opening between the rear ends of the two curved plows 1 can allow coke that is not carried away by the air conveying pipe to overflow from the rear end.

[0026] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
