Description

Technical Field

[0001] This utility model relates to the field of coal slag treatment technology, and more specifically, it relates to a coal gasification slag mixing machine. Background Technology

[0002] Coal gasification slag is the residue produced during the high-temperature gasification process of coal. It is mostly grayish-black in color, with irregular particle shapes and a rough, porous surface. Based on its physical morphology, it is classified into coarse slag, fine slag / fly ash, and glassy slag. Coarse slag typically has a particle size greater than 5 mm, while fine slag has a particle size mostly below 100 μm, exhibiting a large specific surface area. Density tests show that the true density of coal gasification slag is generally between 2.5 and 2.8 g / cm³, the bulk density is approximately 1.0 to 1.4 g / cm³, and the porosity is as high as 40%-60%. This porous structure gives it excellent adsorption properties and lightweight characteristics.

[0003] With the growth of global energy demand and the pursuit of clean energy, coal gasification technology, as a highly efficient coal conversion method, has been widely applied and developed. During the coal gasification process, a large amount of coal gasification slag is generated.

[0028] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0029] Example: A coal gasification slag mixing machine, such as Figure 1 , Figure 2 As shown, the system includes a mixing tank 1. A second motor 6 is vertically mounted at the top center of the mixing tank 1. A feed inlet 7 is located on one side of the second motor 6 at the top of the mixing tank 1. A stirring shaft 8 is mounted at the output end of the second motor 6 and passes through the top of the mixing tank 1. A stirring rod 9 is mounted on the stirring shaft 8. A first motor 5 is mounted at the bottom center of the mixing tank 1. A rotating shaft is mounted at the output end of the first motor 5 and passes through the bottom of the mixing tank 1. A scraper 10 is mounted on the side of the rotating shaft located inside the mixing tank 1. The bottom surface of the scraper 10 is in contact with the inner wall of the mixing tank 1. The bottom of the mixing tank 1 is also provided with a support foot 2 and a discharge port. A movable baffle 4 is movably connected to the discharge port.

[0030] By adopting the above technical solution, motor 2 6 drives the stirring shaft 8 to rotate the stirring rod 9, which can stir and mix the coal gasification slag in the mixing tank 1. The structural design of the stirring rod 9 can increase the contact area with the coal gasification slag and improve the uniformity of stirring. Motor 1 5 drives the rotating shaft to rotate the scraper 10. The scraper 10 is in contact with the inner wall of the mixing tank 1, which can scrape off the coal gasification slag attached to the bottom and inner wall of the mixing tank 1 to avoid material accumulation. At the same time, it assists the material to move towards the discharge port. The support foot 2 provides stable support for the mixing tank 1. The movable baffle 4 can control the opening and closing of the discharge port, which is convenient for controlling the timing and speed of discharge.

[0031] Further configuration: The mixing tank 1 is equipped with a crusher 3 at the top inlet 7; the crusher 3 includes a feed trough 301 and a shell 302, the top of the shell 302 being connected to the bottom of the feed trough 301; the bottom of the feed trough 301 is provided with a first inclined plate 310 and a second inclined plate 311 on both sides respectively, the bottom of the first inclined plate 310 is provided with a vertical plate 313, and the bottom of the vertical plate 313 is provided with a third inclined plate 314; the bottom of the second inclined plate 311 is provided with an arc-shaped... A guard plate 308; a roller 312 is provided between the upright plate 313 and the guard plate 308. Both ends of the roller 312 penetrate the housing 302 and a motor 305 is provided at one end; a funnel-shaped material collection trough 307 is provided below the inclined plate 314 and the guard plate 308. A discharge port 306 is provided at the bottom of the material collection trough 307; the bottom of the housing 302 is detachably connected to the top of the mixing tank 1, and the discharge port 306 extends into the mixing tank 1 through the inlet port 7.

[0032] By adopting the above technical solution, the slag crusher 3 can crush the gasification slag before it enters the mixing tank 1, solving the problem of low mixing efficiency caused by the high hardness and irregular shape of the gasification slag. The gasification slag is fed into the feed chute 301, guided by inclined plate 1 310 and inclined plate 2 311 to roller 1 312. Motor 5 305 drives roller 1 312 to rotate, performing preliminary crushing of the gasification slag. The crushed material is guided by inclined plate 3 314 and guard plate 308 to the collection chute 307, and then enters the mixing tank 1 through the discharge port 306. The detachable housing 302 facilitates the inspection and maintenance of the internal components of the slag crusher 3.

[0033] Further configuration: the bottom of the inclined plate 314 and the guard plate 308 are both provided with a protective shell 309, and rollers 2 315 and 3 316 are arranged side by side between the opposite protective shells 309; both ends of rollers 2 315 and 3 316 penetrate the shell 302, one end of rollers 2 315 is provided with motor 4 304, and one end of rollers 316 is provided with motor 3 303; the collection trough 307 is located below rollers 2 315 and 3 316.

[0034] By adopting the above technical solution, the gasification slag, after initial crushing by roller 1 312, will further fall between roller 2 315 and roller 3 316. Motor 4 304 and motor 303 respectively drive roller 2 315 and roller 3 316 to rotate, performing secondary crushing of the material, making the gasification slag particles finer and more uniform, laying a good foundation for subsequent mixing processes and significantly improving mixing efficiency. The protective shell 309 can protect roller 2 315 and roller 3 316, and at the same time prevent material from splashing during the crushing process.

[0035] Further configuration: The top of the mixing tank 1 is provided with an inspection port, and the inspection port is provided with a cover plate 12.

[0036] By adopting the above technical solution, staff can inspect, maintain and clean the mixing tank 1's internal components such as the stirring shaft 8, stirring rod 9, and scraper 10 by opening the cover plate 12 and accessing the inspection port. This eliminates the need for complete disassembly of the equipment, reducing maintenance difficulty, saving maintenance time, and ensuring long-term stable operation of the equipment.

[0037] Further configuration: The bottom of the scraper 10 is provided with bristles.

[0038] By adopting the above technical solution, the brush bristles can further enhance the cleaning effect of the scraper 10 on the inner wall of the mixing tank 1. In particular, the brush bristles can effectively remove fine dust and particulate materials adhering to the tank wall, avoid material accumulation affecting the mixing effect, reduce dust wear on equipment parts, and extend the service life of the equipment.

[0039] Further settings include: the number of scrapers 10 is 2 and they are set relative to each other.

[0040] By adopting the above technical solution, the two oppositely arranged scrapers 10 can scrape the material at the bottom and inner wall of the mixing tank 1 from different directions during the rotation process, thereby improving the scraping efficiency and coverage, avoiding cleaning dead corners, and at the same time pushing the material to the discharge port more evenly to ensure smooth discharge.

[0041] Further settings include: the number of stirring rods 9 is 2-4.

[0042] By adopting the above technical solution, the setting of 2-4 stirring bends 9 can ensure the stirring effect while avoiding excessive equipment load due to an excessive number of stirring bends 9. Multiple stirring bends 9 working together can stir the material from different heights and angles when the stirring shaft 8 rotates, making the coal gasification slag more uniformly mixed and meeting different mixing requirements.

[0043] Further configuration: The stirring shaft 8 is provided with spiral blades 11 along the extension direction.

[0044] By adopting the above technical solution, when the spiral blades 11 rotate with the stirring shaft 8, they can tumble the material in the mixing tank 1, breaking the stratification of the material in the vertical direction and making the material mix more thoroughly. At the same time, the spiral blades 11 can also help to convey the material at the bottom upwards, forming a three-dimensional stirring effect in conjunction with the stirring rod 9, further improving the mixing efficiency and uniformity.

[0045] Further configuration: The inner wall of mixing tank 1 is provided with a wear-resistant coating.

[0046] By adopting the above technical solution, the wear-resistant coating can effectively improve the wear resistance of the inner wall of the mixing tank 1, extend its service life, and reduce equipment maintenance costs, as the coal gasification slag has high hardness and is prone to wear during the mixing process. The wear-resistant coating can be a ceramic coating or a tungsten carbide coating, which has high hardness and wear resistance and can adapt to the harsh working conditions of coal gasification slag mixing.

[0047] Working Principle: When using this coal gasification slag mixer, the coal gasification slag is first fed into the feed chute 301 of the crusher 3. Motors 303, 304, and 305 are then started. Motor 305 drives roller 1 312 to rotate, performing initial crushing of the material. The initially crushed material falls between rollers 2 315 and 316. Motors 303 and 304 drive rollers 2 315 and 316 to rotate, performing secondary crushing of the material. The crushed material then enters the mixing tank 1 through the collection chute 307 and discharge port 306. Motor 2 6 is then started, driving the stirring shaft 8 to rotate the stirring rod 9 and the spiral blades 11. The stirring rod 9 stirs the material horizontally, while the spiral blades 11 tumble the material vertically, achieving uniform mixing. After the materials are mixed, the worker holds the handle on the movable baffle 4 to open it, and the evenly mixed coal gasification slag is discharged from the outlet, completing the mixing operation. Simultaneously, motor 5 is started, driving the rotating shaft to rotate scraper 10. The bristles at the bottom of scraper 10 clean the material at the bottom and inner wall of mixing tank 1, preventing material accumulation and assisting the material in moving towards the outlet. When the equipment requires maintenance, the worker opens the top cover 12 of mixing tank 1 and uses the inspection port to inspect and clean components such as the stirring shaft 8, stirring bend 9, and scraper 10 inside mixing tank 1; maintenance may also be required on the slag crusher 3.

[0048] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
