Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solid waste treatment, in particular to a coal gangue and coal slime comprehensive utilization solid waste treatment machine and use method. BACKGROUND

[0002] Coal gangue is a solid waste generated in the process of coal mining and washing, which is rich in silicon, aluminum, carbon and other components, and has the characteristics of high hardness, coarse particles and low water content. Coal slime is a fine particle high-moisture material generated in the coal washing process of a coal preparation plant, which has high viscosity and poor flowability. Both of them belong to the bulk solid waste of the coal industry, and through comprehensive utilization technology, they can be converted into building materials, fuels, chemical raw materials and other products, which is an important way to realize the green and low-carbon development of the coal industry. In the collaborative utilization scene of coal gangue and coal slime (such as the preparation of ceramsite, sintered brick, biomass fuel, etc.), the physical properties of the two are significantly different, leading to difficulty in mixing. Specifically, the particle size and density of coal gangue are larger than those of coal slime. In addition, the flowability of the two is different. Coal gangue is in a bulk state when it is stacked, and has good flowability. However, coal slime is in a powdery state after drying, so the mixing device needs a long time for stirring operation to make the materials mix evenly. If the mixing is not uniform, it will directly affect the stability of the subsequent process and the quality of the product. For example, in the preparation of sintered bricks, uneven mixing will cause the strength of the green body to fluctuate and cracking during the sintering process. In the preparation of non-burning bricks, the uneven distribution of gel materials and additives will cause the hardness of the brick body to be substandard after forming. In the preparation of fuel, local over-concentration of coal slime may cause incomplete combustion, excessive emission of pollutants and other problems.

[0003] At present, the equipment for mixing coal gangue and coal slime is mainly vertical mixers and horizontal mixers. Although the mixing time can be increased to make the materials mix evenly, the processing and mixing time and energy consumption are increased. Moreover, after each mixing is completed, the machine must be stopped to complete the feeding and discharging, and the humidity of the mixed materials cannot be increased during the processing process, resulting in a large amount of dust.

[0033] (Three) beneficial effects

[0034] Compared with the prior art, the coal gangue and coal slime comprehensive utilization solid waste treatment machine and the use method have the following beneficial effects:

[0035] 1. By adopting the mixing box and setting the curved material running path in the mixing box, the airflow and the main material and the auxiliary material can be synchronously curved flowing, so that the airflow mixing can be carried out in the running process, and the mechanical pushing structure is arranged at the node of the curved running path, directly assisting the airflow to transport the material to avoid blockage, and also effectively mechanically stirring and mixing, which can effectively improve the uniformity of the mixed material, and also can realize continuous feeding and continuous discharging through the flowing mixing mode, significantly reducing the mixing operation time.

[0036] 2. By applying compressed gas at the feeding end to blow away the large amount of main material, the blown away main material mixes with the airflow to blow away a small amount of auxiliary material, and finally discharges from the turbulence passage, so that the airflow can realize the effect of flowing mixed material, and the feeding congestion is not easy to cause.

[0037] 3. By setting a spiral lifting component at the node where the airflow and the mixture flow, not only can the mixture be transferred quickly, but it can also generate agitation and mixing when lifting the material. In addition, when the airflow passes through the spiral path formed by the spiral blades, it can also assist the mixture to move upward and mix.

[0038] 4. Through airflow mixing, the main and auxiliary materials can be continuously conveyed and mixed. The humidity is increased at the end of the mixing process, so that the relatively dry coal slime powder can adhere to the surface of the fine coal gangue particles, making the mixed material less prone to separation. This not only reduces dust generation during processing, but also facilitates transportation and storage. When used in industrial production fields such as pulverized coal boiler combustion power generation, industrial kiln heating, and coking coal blending, the coal slime coating the surface of the coal gangue makes it easier for the coal gangue to burn, playing a role in combustion assistance, without the need to add gels or additives.

[0057] The technical scheme has the characteristics that the compressed gas is applied at the feeding end to first blow the main material with a large amount, the blown main material mixes with the gas flow to blow the auxiliary material with a small amount, and finally the mixed material is discharged from the spoiler passage, so that the effect of realizing the flow type mixed material can be achieved by using the gas flow, and the feeding congestion is not easy to occur.

[0058] As shown, Figures 4-5 The technical scheme of the discharging assembly includes a cylindrical shell 11, the side wall of the mixing box 1 is fixedly connected with the side wall of the shell 11 through a circular hole, and the shell 11 is in close contact with the bottom of the mixing box 1, so that the gas and the mixed material in the mixing channel are not leaked into the mixing box 1, two partitions 24 are fixedly connected in the shell 11, the interval distance between the two partitions 24 is equal to the width of the baffle 12, the shell 11 is divided into a primary discharging chamber 28 and two secondary discharging chambers 29 by the two partitions 24, and a feeding opening 31 is formed in one side of the shell 11. Figure 3The lowest feeding port 31 is consistent with the inner wall of the mixing box 1, so that the mixed material and the airflow can smoothly enter the first discharge chamber 28. The other side of the shell 11 is provided with a discharge port 30 which is higher than the feeding port 31. The mixed material carried by the airflow can be thrown out. The part of the discharge port 30 which communicates with the second discharge chamber 29 is fixedly connected with two flow guides 10. The lower ends of the two flow guides 10 are fixedly connected with connecting pipes. The lower ends of the connecting pipes pass through the side wall of the mixing box 1 and are fixedly connected with the upper ends of the guide pipes 23. The center of the baffle 24 is rotatably connected with a main shaft 32 through a sealing bearing. The shaft wall of the main shaft 32 is provided with a material stirring assembly.

Since the horizontal pipe discharges from the two ends, at this time, the mixed material will be more concentrated at the folded edge of the baffle 12, causing the material to be unevenly discharged into the first discharge chamber 28. At this time, the material stirring wheels 25 arranged can throw out the accumulated material when rotating. After being thrown out, the material is thrown out of the first discharge chamber 28 by the material stirring plate 27 and the mixing plate 26.

The specific power component is a gear ring 40 fixedly connected to the tube wall of the sleeve. A gear shaft 39 is meshed on one side of the gear ring 40. The gear shaft 39 is provided with two tooth surfaces of different sizes, and the middle part is the smooth shaft part. The gear shaft 39 is rotatably connected to the inner wall of the vertical tube 3 via a bearing seat. A gear 38 is meshed on one side of the gear shaft 39. The gear 38 is fixed to the shaft wall of the vertical shaft 20. At this time, the number of teeth of the gear 38 is greater than the tooth surface of the gear shaft 39 that meshes with it, while the larger tooth surface at the lower end of the gear shaft 39 is slightly smaller than the gear ring 40. In this way, the speed can be increased.

[0063] In order to supplement the airflow so that the mixture can be mixed and flowed in time, the technical scheme adopted is that a blind hole 43 is formed in the upper end of the vertical shaft 20, two air inlet holes are formed in the shaft wall of the vertical shaft 20 and communicated with the blind hole 43, a plurality of air outlet holes are formed in the shaft wall of the vertical shaft 20 and communicated with the blind hole 43, the air outlet holes are located below the annular plate 41 and correspond to the positions of the arc-shaped plates 42, the pipe wall of the stand pipe 3 is fixedly connected with an air inlet pipe, the pipe wall of the air inlet pipe is fixedly connected with an air valve, compressed gas is supplemented into the stand pipe 3 through the air inlet pipe, the compressed gas enters from the air inlet holes and is discharged from the air outlet holes below the annular plate 41, and the discharged airflow mixes with the mixture between the plurality of arc-shaped plates 42, so that the dust in the mixture carried by the airflow can be avoided from entering and affecting the operation of the transmission gear set, and the heat generated by the transmission gear set can also be taken away by the airflow.

[0064] The above technical scheme sets the spiral lifting assembly at the node of the airflow and the mixture flow, which not only can quickly transfer the mixture, but also can stir and mix the mixture when lifting the material. In addition, the airflow passing through the spiral path formed by the spiral blade 21 can also assist the mixture to move upward and mix.

[0065] As shown in Figures 2-3 and Figure 10 The mixing assembly includes a rotating shaft 46, the rotating shaft 46 is rotatably connected at the center of the discharge box 2 through a sealing bearing, the lower end of the rotating shaft 46 extends into the discharge box 2 and is fixedly connected with a plurality of circumferentially distributed paddles 45, the paddles are arranged in the material falling area in the discharge box 2, and the gap between the edges and the inner wall of the cylinder 44 is controlled to be 0.5-1 mm, the plurality of paddles 45 are used to break up the mixture in the falling process, so that the mixture forms dust raising in the discharge box 2 to realize re-mixing, the lower end of the mixing box 1 is fixedly connected with a conical bottom capable of gathering the mixture, the discharge pipe 9 is fixed at the lower end of the conical bottom, the lower end of the rotating shaft 46 is fixedly connected with a discharge auger 15, the discharge auger 15 extends into the discharge pipe 9 and is used to discharge the gathered mixture in time, a plurality of exhaust cloth bags 8 are installed at the upper end of the discharge box 2 and are mainly used to discharge compressed gas, so that the mixture can settle in the discharge box 2. In addition, since the second motor 4 used for discharging is a reduction motor, it has a large torque, so the first pulley 48 can be directly fixed at the upper end of the rotating shaft 46, the second pulley 47 is fixed at the lower end of the vertical shaft 20, and the belt 22 is wound between the first pulley 48 and the second pulley 47, so as to fully utilize the power of the second motor 4, and the rotating speed can be adjusted by adjusting the diameter of the first pulley 48 or the diameter of the second pulley 47, so as to change the transmission speed ratio and make the plurality of paddles 45 at a suitable rotating speed. The upper end of the mixing box 1 is fixedly connected with a protective cover to prevent foreign matters from winding on the belt 22.

[0066] In order to make the mixture better mixed by the paddle 45 when falling, a cylinder 44 can be fixedly connected in the inner wall of the upper end of the discharge box 2, two elbow pipes 36 are obliquely arranged in the cylinder 44, as shown in Figure 10 The two elbow pipes 36 can form four oppositely arranged discharge ports, and the cyclone can be formed by the structure of the cylinder 44 after discharging, which can slow down the falling speed of the mixture in the airflow. The lower end of the guide pipe 23 extends into the cylinder 44 and is fixedly connected with the pipe wall of the elbow pipe 36. The side wall of the cylinder 44 is fixedly connected with a plurality of atomizing nozzles 14. The water inlet end of the atomizing nozzle 14 extends to the outside of the discharge box 2 and is fixedly connected with a solenoid valve. The atomizing nozzles 14 arranged can directly spray water mist on the material in the cylinder to increase the humidity of the mixture. Increasing humidity can reduce dust, and is beneficial to the settlement of the mixture at the discharge pipe 9. The water spraying amount can be configured according to different production needs to meet the production needs.

[0067] The use method of the above technical solution is:

[0068] The automatic feeding machine is used to send the main material and the plurality of auxiliary materials from the auxiliary material pipe 35 and the main material pipe 17 respectively. For example, when coal gangue (particle size controlled at 0.5-2mm) is used as the main material to make the coal gangue and coal slime to make the unfired brick, the proportion of the coal gangue is 70%-85%, the proportion of the coal slime in the auxiliary material is 15%-30%, the proportion of the gel material (cement) and the additive is 10%-15%, and the compressed gas is sent from the compressed gas pipe. The air outlet nozzles 34 arranged oppositely are used to blow the main material first and then blow the auxiliary material to preliminarily form the mixture. The mixture is discharged into the mixing channel after passing through the turbulence passage with the airflow. Part of the mixture in the mixing channel can pass through the shell 11 by itself, and the other part needs to be discharged by rotating the material stirring assembly driven by the first motor 7, so that the mixture entering the first-stage discharge chamber 28 with the airflow is discharged from the discharge port 30. The discharged mixture falls into the mixing box 1 and enters the material inlet of the lifting assembly. The second motor 4 drives the vertical shaft 20 to rotate the spiral blade 21, so that the mixture rises and is discharged from the material outlet. The arc-shaped plate 42 timely scatters and discharges the mixture accumulated at the material outlet. Under the guiding action of the guide plate 18, the mixture slides into the two second-stage discharge chambers 29. The material stirring assembly in the second-stage discharge chamber 29 discharges the mixture into the guide pipe 23, which enters the discharge box 2 under the action of the airflow. The mixture falling is mixed again by the mixing assembly, and the water mist is sprayed from the atomizing nozzle 14 connected to the water pump to fuse with the falling mixture, so as to reduce the dust in the airflow and increase the humidity of the mixture. The uniform mixture is discharged.

[0069] The method matches the advantages of the technical scheme, and continuous conveying and mixing of the main material and the auxiliary material can be realized through airflow mixing, humidity is increased at the end of mixing, and the relatively dry coal slime powder can be adhered to the surface of the coal gangue fine particle, the mixed mixture is not easy to separate, dust generation in the processing process can be reduced, transportation and storage are facilitated, when the mixed mixture is used in the industrial production fields of coal powder boiler combustion power generation, industrial kiln heat supply, coking coal blending, etc., the coal slime wrapped on the surface of the coal gangue is easier to make the coal gangue burn, and plays a combustion supporting role, without adding gel and additives.
