Description

Technical Field

[0001] This utility model relates to the field of petroleum coke mixing, and in particular to an intelligent mixing device for petroleum coke processing. Background Technology

[0002] To enhance the mechanical strength and thermal stability of asphalt after paving, and to reduce costs by leveraging the low price of petroleum coke, it is common practice to mix petroleum coke with asphalt to improve its performance. In the mixing process, the asphalt is first heated to a liquid or semi-fluid state, and then crushed petroleum coke is gradually added. This ensures thorough contact and uniform mixing, thereby improving the homogeneity and quality of the mixture. Currently, the method of adding petroleum coke powder is usually to pour it directly into the mixing container, allowing it to fall and contact the asphalt, followed by stirring to mix them. However, petroleum coke powder is relatively light, and the pouring process is highly likely to generate dust. This dust requires time to settle, hindering the thorough mixing of the added petroleum coke powder with the asphalt and extending the overall mixing and stirring cycle.

[0003] In summary, this application proposes an intelligent mixing device for petroleum coke processing, which improves the aforementioned technical problems. Utility Model Content

[0004] To overcome the shortcomings of petroleum coke powder being lightweight and highly likely to generate dust during the pouring process, which requires a certain amount of time to settle and allow the added petroleum coke powder to fully mix with asphalt, thus prolonging the overall mixing and processing cycle, this utility model provides an intelligent mixing device for petroleum coke processing.

[0020] Example 1

[0021] A smart mixing device for petroleum coke processing, with reference to Figures 1-4 As shown, it includes a fixed bracket 1 and a mixing tank 2; the fixed bracket 1 is equipped with the mixing tank 2;

[0022] It also includes a motor 3, a rotating rod 4, an agitator 5, a heating element 6, a discharge pipe 7, an electric push rod 8, a pressure plate 9, a movable plate 10, a feeding pipe 11, and a limiting ring 12; the motor 3 is bolted to the surface of the upper cover 01 of the mixing tank 2; the upper cover 01 is rotatably connected to the rotating rod 4, and the rotating rod 4 is fixedly connected to the output shaft of the motor 3; three agitator 5 are fixedly connected to the rotating rod 4; a heating element 6 is installed in the tank body interlayer of the mixing tank 2, and the heating element 6 is connected to an external power source; the bottom of the mixing tank 2 is connected to the discharge pipe 7, and a valve is installed on the discharge pipe 7; two electric push rods 8 are fixedly connected to the upper cover 01; the upper cover 01 has several ventilation holes; the telescopic parts of all the electric push rods 8 pass through the upper cover 01 and are all fixedly connected to a pressure plate 9 with a sealing ring on the edge, and the pressure plate 9 is equipped with several downward-opening one-way valves, and the pressure plate 9... The pressure plate 9 slides in contact with the inner wall of the mixing tank 2; the pressure plate 9 is connected to a movable plate 10 with a sealing ring on the edge via a spring rod. The slide bar of the spring rod passes through the pressure plate 9 and is slidably connected to the pressure plate 9. A limiting protrusion is provided at the upper end of the slide bar of the spring rod to limit the pressure plate 9, so that the pressure plate 9 always slides on the slide bar of the spring rod. The spring of the spring rod is wrapped around the outside of the slide bar, and the upper end of the spring rod is fixed to the bottom of the pressure plate 9, and the lower end is fixed to the upper part of the movable plate 10. The movable plate 10 slides in contact with the inner wall of the mixing tank 2; the movable plate 10 is connected to four feeding pipes 11 arranged in a ring array. An openable and closable valve is provided at the lower outlet of the feeding pipe 11 to isolate asphalt, and a downward-opening one-way valve is provided inside the feeding pipe 11; a limiting ring 12 that matches the movable plate 10 is fixedly connected to the inner wall of the mixing tank 2.

[0023] The lower end of the feeding pipe 11 is set in a conical shape to facilitate the injection of petroleum coke powder inside the feeding pipe 11 into the asphalt, while reducing the possibility of asphalt entering the feeding pipe 11 from the outlet of the feeding pipe 11.

[0024] A cover is provided on the feeding pipe 11, and the cover is configured as a filter screen. When petroleum coke powder is added into the feeding pipe 11, the cover is manually placed over the opening of the feeding pipe 11 to prevent the petroleum coke powder in the feeding pipe 11 from falling out during the installation of the cover 01.

[0025] It also includes scraper blades 101; all the stirring blades 5 are fixedly connected to two scraper blades 101, and the scraper blades 101 are in contact with the inner wall of the mixing tank 2.

[0026] The mixing tank 2 is equipped with a temperature sensor that can monitor the temperature inside the mixing tank 2 in real time, thereby intelligently adjusting the working time of the heating element 6 to ensure that the petroleum coke and asphalt are always at the optimal temperature during the mixing process.

[0027] The feeding tube 11 is made of high-temperature resistant material and can be used normally in high-temperature environments.

[0028] In existing technology, the mixing tank is usually opened by a person first, asphalt is added into the mixing tank, and then the mixing tank is closed. Next, the mixing tank is heated to heat the asphalt to a liquid or semi-fluid state. Then, a predetermined amount of petroleum coke powder is added into the mixing tank through the feeding channel to contact the asphalt. Then, the operation of the mixing tank is controlled to fully mix the two in contact.

[0029] However, petroleum coke powder is relatively light, and the pouring process is highly likely to generate dust. This dust takes time to settle, hindering the thorough mixing of the added petroleum coke powder with the asphalt and prolonging the overall mixing and processing cycle. To address this issue, firstly, the top cover 01 and other connected parts are manually removed, and the mixing tank 2 is opened. Then, asphalt is added to the mixing tank 2. Next, during the addition of petroleum coke powder, it is no longer poured directly into the mixing tank 2. Instead, a fixed amount of petroleum coke powder is manually and evenly added to the four feeding pipes 11 using a flexible feeding pipe. A mesh cover is then placed over the opening of the feeding pipes 11 to prevent the added petroleum coke powder from falling out, thus reducing the predetermined content of petroleum coke powder and affecting the overall petroleum coke content. The powder and asphalt are mixed, and then the top cover 01 and other connected parts are moved and reset to their original positions. The mixing tank 2 is then covered, and the heating element 6 is activated by an external power supply. The heating element 6 heats the asphalt to a liquid or semi-fluid state. Then, the motor 3 drives the rotating rod 4 and the stirring blade 5 to rotate. During the subsequent stirring process of the stirring blade 5, the electric push rod 8 drives the pressure plate 9 to move downward. The pressure plate 9 drives the spring rod to move downward, which in turn drives the movable plate 10 and the feeding pipe 11 to move downward. When the movable plate 10 moves downward and contacts the limiting ring 12, the movable plate 10 stops moving downward due to the limitation of the limiting ring 12. At this time, the feeding pipe 11, driven by the movable plate 10, inserts its lower end into the asphalt, and under the action of the valve, the asphalt... Unable to enter the feeding pipe 11; then, the electric push rod 8 is controlled to push the pressure plate 9 downward, the spring rod retracts, and the pressure plate 9 moves to compress the space between the pressure plate 9 and the movable plate 10, thus reducing the space and increasing the pressure. The feeding pipe 11 is equipped with a downward-opening one-way valve. Under the action of air pressure, the gas drives the petroleum coke powder in the feeding pipe 11 to open the one-way valve and the lower valve, injecting it into the asphalt, completing the addition of petroleum coke powder. The lower end of the feeding pipe 11 moves and inserts into the asphalt, directly spraying the petroleum coke powder into the asphalt. Compared to the existing method of directly pouring the petroleum coke powder into the mixing container through the mixing container opening, causing the petroleum coke powder to sink and contact the asphalt, this equipment can... Petroleum coke powder comes into direct contact with asphalt, shortening the overall mixing and processing cycle. When the spring rod retracts to its limit, the pressure plate 9 stops moving. Then, the electric push rod 8 drives the pressure plate 9 to move upward and reset. After the pressure plate 9 moves upward and contacts the limiting protrusion of the spring rod, the pressure plate 9 drives the spring rod to move upward together. The spring rod drives the movable plate 10 and other connected parts to move upward. The pressure plate 9 is equipped with a downward-opening one-way valve. During the upward reset process of the pressure plate 9, external gas enters between the pressure plate 9 and the movable plate 10 through the through hole of the upper cover 01 and the one-way valve on the pressure plate 9, causing the spring rod to return to its original shape. The feeding pipe 11 is equipped with a downward-opening one-way valve. During the reset process, asphalt cannot enter the feeding pipe 11.It is important to note that the mixing tank 2 is equipped with a temperature sensor that monitors the internal temperature in real time, thereby intelligently adjusting the working time of the heating element 6 to ensure that the petroleum coke and asphalt are always mixed at the optimal temperature.

[0030] Furthermore, when the mixed mixture is discharged, the motor 3 continues to drive the stirring blade 5 and the scraper 101 to rotate. The scraper 101 can scrape the inner wall of the mixing tank 2 to remove the mixture adhering to the inner wall of the mixing tank 2, thus preventing the mixture from sticking to the inner wall of the mixing tank 2 and being difficult to discharge.

[0031] After one batch of asphalt is mixed, the mixing tank 2 is manually reopened to clean the remaining asphalt inside the mixing tank 2 and the remaining asphalt on the feeding pipe 11, so as to avoid affecting the proportion of the materials to be mixed in the next batch and to prevent the port flap from being blocked.

[0032] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
