Abstract
Description
Technical Field
[0001] This utility model relates to a coal gangue recycling and processing device, belonging to the technical field of mixing and stirring equipment. Background Technology
[0002] Coal gangue is a solid waste discharged during coal mining and washing. It is a dark gray rock with low carbon content and harder than coal, which is associated with coal seams during coal formation. It includes gangue from tunneling, gangue extracted from the roof, floor, and interlayers during mining, and washed gangue from coal washing. Coal-associated waste rock is a type of mining solid waste discharged during tunneling, mining, and coal washing. It includes washed gangue from coal washing plants, hand-sorted gangue from coal production, coal and rock discharged from semi-coal roadways and rock roadways, and a mixture of white gangue and other non-coal-series materials piled together with coal gangue. Coal gangue is a mixture of carbonaceous, argillaceous, and sandy shale with a low calorific value. It contains 20-30% carbon and some contain humic acid. Coal gangue is mainly used to produce lightweight aggregates for gangue cement and concrete, refractory bricks and other building materials. In addition, it can be used to recycle coal, co-fire coal and gangue for power generation, produce chemical products such as crystalline aluminum chloride and water glass, extract precious and rare metals, and also be used as fertilizer.
[0003] Coal gangue can be used to manufacture building materials. With a total content of over 80% silica, ferric oxide, and aluminum oxide, it is a natural clayey raw material that can be used to produce various special-purpose cements for construction, such as ordinary silicate cement, special cement, and clinker cement, reducing the need for arable land excavation. In brick-making, the combustible material of coal gangue itself can be used, saving coal. Coal gangue that has spontaneously combusted or been artificially burned possesses a certain degree of activity and can be used as an active admixture in cement production, producing ordinary silicate cement, pozzolanic cement, and low-clinker cement. It can also be directly mixed with lime and gypsum in appropriate proportions to produce clinker-free cement, which can be used as a binder. It can be used as aggregate in the production of concrete blocks or hollow concrete blocks, using fluidized bed slag or gravel and fluidized bed slag as coarse and fine aggregates. Countries like the UK and Belgium have factories that use coal gangue to replace siliceous raw materials in cement production. In addition, coal gangue can also be used to produce low-calorific-value coal gas, manufacture ceramics, make soil conditioners, or for paving roads, underground filling, and surface filling for land reclamation. Grass and trees can also be planted on the gangue hills after spontaneous combustion to beautify the environment.
[0004] Chinese invention patent disclosure entitled "Spiral Mixer", application publication number CN109663526A, describes its structure as follows: It includes a frame 1, a material cylinder 2 mounted on the frame, a feeding channel 3 at the upper end of the material cylinder 2, a hopper 30 at the upper end of the feeding channel, and a discharge channel 4 at the lower end of the material cylinder 2. The material cylinder has a U-shaped cross-section, and a gate 5 is provided at the discharge channel. Two parallel spiral rods 31 are located in the feeding channel 3, connected by gears. A first motor 32 connected to the spiral rods is located outside the feeding channel 4. The two spiral rods rotate synchronously in opposite directions under the drive of the first motor. When powdered material is poured into the hopper, the material flows out from between the two spiral rods... The material enters the cylinder through the gap, and the clumped material is broken up by the screw. The cylinder 2 has coaxial support shafts 6 on opposite sides, and connecting discs 7 on the support shafts 6. A stirring shaft 8 is located between the two connecting discs 7. The stirring shaft 8 has several stirring blades 9, which are spiral ribbons. The two ends of the stirring blades are fixedly connected to the stirring shaft through connecting rods 10. The distances from the two ends of the stirring blades to the stirring shaft are different, so that the material at different diameter positions can be stirred and mixed when the stirring shaft rotates. The side of the cylinder 2 has a second motor 11 and a reducer 12. The input shaft of the reducer is connected to the second motor through a pulley 13 and a belt 14. The output shaft of the reducer 12 is coaxially connected to one of the support shafts.
[0005] The disadvantages of this patent are that the bottom of the frame 1 is not designed with casters, making it inconvenient to move the machine; the discharge channel 4 is open, making it impossible to control the flow rate during discharge; and the feed channel 3 is not designed with a filter device, which can easily lead to large stones being mixed in and damaging the mixer. In view of the above technical problems, further technical improvements are needed to facilitate the mixing and processing of coal gangue powder. This is a technical problem that urgently needs to be solved. Utility Model Content
[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a coal gangue recycling and processing device.
