Description
Technical Field
[0001] This utility model relates to the field of coal powder processing technology, specifically to an intelligent pre-mixing system. Background Technology
[0002] Powdered coal is a fine powdery substance formed by crushing and grinding raw coal. Its particle size is usually between 0.01 and 0.1 mm, and its appearance is mostly grayish-black or brown. In order to improve the forming stability, transportation performance, combustion characteristics and industrial applicability of powdered coal, it is usually extruded and formed to facilitate subsequent coking treatment. Before extrusion and forming, powdered coal needs to be stirred by a pre-stirring system. In the powdered coal processing flow, pre-stirring is a key preliminary step to ensure the subsequent forming, combustion or gasification effect. By mixing materials, homogenizing components and optimizing physical properties, it lays the foundation for process stability. Intelligent pre-stirring systems can fully mix different coal types, additives, binders, desulfurizers, etc., to avoid uneven forming or coking caused by local component differences. However, existing intelligent pre-stirring systems are not convenient to scrape off the powdered coal adhering to the inner wall during use, and are not convenient to guide additives. The stirring efficiency is slow and the use is inconvenient. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1-5 The present invention provides a technical solution: an intelligent pre-mixing system, including a box body 10, a cover 20, a motor 30, a pipe 301, a rotating shaft 302, a scraper 303, a mixing rod 304, a receiving groove 305, a guide groove 306, a hole 307, a discharge port 40, a feed port 50, a moving rod 501, a first receiving plate 502 and a second receiving plate 503;
[0033] This intelligent pre-mixing system facilitates the addition of pulverized coal. The specific implementation method is as follows:
[0034] The bottom surface of the housing 10 is equipped with a discharge port 40, and the surface of the cover 20 is embedded with a feed port 50. The feed port 50 is internally connected to a first support plate 502 and a second support plate 503. The surfaces of the first support plate 502 and the second support plate 503 are both connected to a moving rod 501. The outer side of the feed port 50 is in contact with the inner wall of the first support plate 502, and the first support plate 502 and the feed port 50 are connected by sliding friction. The second support plate 503 is located inside the housing 10, and the feed port 50 is connected by sliding friction between the second support plate 503 and the feed port 50.
[0035] Pull the lever 501 upwards, causing the first receiving plate 502 and the second receiving plate 503 to move upwards simultaneously. The first receiving plate 502 moves upwards inside the feed inlet 50, then moves out of the feed inlet 50. Meanwhile, the second receiving plate 503 moves from inside the housing 10 to the bottom of the feed inlet 50, blocking the material from escaping. At this point, pulverized coal is poured into the feed inlet 50. Coal powder falls onto the surface of receiving plate 2 503. After the coal powder is added, push the moving rod 501 downwards, causing the moving rod 501 to push receiving plate 1 502 and receiving plate 2 503 downwards. This causes receiving plate 1 502 to move into the feed inlet 50, where it blocks the feed inlet 50 to prevent coal powder from overflowing. Receiving plate 2 503 moves into the box 10, at which point the coal powder on the surface of receiving plate 2 503 enters the box 10. Coal powder is added in small amounts and multiple times.
[0036] This intelligent pre-mixing system improves the mixing effect of the device. The specific implementation method is as follows:
[0037] The bottom of the housing 10 is a cylindrical shell with a semi-circular structure, and a cover 20 is installed on the surface of the housing 10. The housing 10 contains a stirring structure, which includes: a motor 30 mounted on the inner surface of the cover 20; a pipe 301 embedded in the surface of the cover 20; a rotating shaft 302 installed inside the housing 10, passing through the cover 20 and connected to the output shaft of the motor 30; stirring rods 304 evenly spaced on the surface of the rotating shaft 302; scrapers 303 connected to the surface of the rotating shaft 302; and a receiving groove 305 connected to the surface of the rotating shaft 302, with guides fixedly connected to the surface of the receiving groove 305. The bottom surface of the guide groove 306 is equidistantly provided with holes 307. The box body 10 and the cover 20 are connected by threads, and the cover 20 and the rotating shaft 302 are connected by rotation. The end of the pipe 301 is positioned corresponding to the receiving groove 305, and the receiving groove 305 is set as a circular structure. The bottom of the stirring rod 304 is set as an arc structure, and the outer side of the stirring rod 304 is attached to the inner wall of the box body 10. The box body 10 and the stirring rod 304 are connected by rotation. The surface of the receiving groove 305 is provided with a notch, and the notch of the receiving groove 305 is positioned corresponding to the guide groove 306, and the guide groove 306 is set as an inclined shape.
[0038] Start the motor 30, so that the output shaft of the motor 30 drives the rotating shaft 302 to rotate, so that the rotating shaft 302 rotates inside the cover 20. At this time, the rotating shaft 302 drives the scraper 303 and the stirring rod 304 on the surface to rotate simultaneously. The stirring rod 304 drives the internal coal powder to stir, mixing the coal powder and the additives. At this time, the scraper 303 rotates on the inner wall of the box 10 to clean the inner wall of the box 10 and scrape off the material stuck to the inner wall of the box 10.
[0039] Simultaneously, additives are injected through pipe 301, allowing them to fall into the receiving tank 305. The additives then move along the opening of the receiving tank 305 to the inside of the guide tank 306, and fall down the slope of the guide tank 306. The additives then fall through the hole 307 to the bottom of the box 10. At the same time, the rotating shaft 302 drives the receiving tank 305 and the guide tank 306 to rotate, changing the discharge position, increasing the contact area, and improving the mixing efficiency.
[0040] Working principle: When using this intelligent pre-mixing system, a moving rod 501, a receiving plate 1 502 and a receiving plate 2 503 are set up to facilitate the addition of coal powder inside. A rotating shaft 302, a scraper 303, a mixing rod 304, a receiving groove 305 and a guide groove 306 are set up to improve the mixing effect of the device and increase the overall practicality.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
