Description

Technical Field

[0001] The present invention relates to the technical field of fly ash mixing, and specifically relates to a low-consumption and high-production continuous fly ash mixer. Background Art

[0002] The existing fly ash mixer is a device specifically used for fly ash treatment, which can continuously receive the input of fly ash and other materials and output the mixed materials at the same time. Fly ash is usually a solid waste generated during the combustion process, and the fly ash mixer can continuously process the fly ash to meet the requirements of subsequent treatment or reuse. However, the following defects still exist in the specific use of the existing technology: 1. In the existing technology, the conveying channel of fly ash is generally installed at one end of the device, so fly ash can only enter the device from this specific position. At the initial stage of device startup, fly ash will first accumulate in the area near the feeding end. When the subsequent spiral stirring shaft starts to rotate, the fly ash near the feeding port will be stirred first. However, since the subsequent fly ash is still continuously entering from this single feeding port, the newly entered fly ash will form a relatively high concentration locally, while the fly ash in the area far from the feeding port arrives relatively late, resulting in uneven initial distribution of fly ash inside the device.

[0003] Moreover, although the spiral stirring shaft can push the fly ash to other areas of the device when rotating, the conveying efficiency of the spiral stirring shaft varies at different positions. The fly ash near the center of the spiral stirring shaft receives a greater pushing force and can move away quickly, while the fly ash near the inner wall of the device moves relatively slowly due to the influence of wall friction. Therefore, when the spiral stirring shaft rotates, the fly ash between the edge of the spiral blade and the inner wall of the device will show a retention phenomenon, resulting in uneven distribution of fly ash on the cross-section of the device.

[0004] 2. At the same time, due to the particle size difference in the raw materials, the coarser particles are relatively heavier in mass and are more likely to settle to the bottom of the device under the influence of gravity during the mixing process. For example, there are some larger particulate substances that are not completely burned in the fly ash. Under the stirring action of the spiral stirring shaft, they are not as easily and fully flipped as the fine fly ash particles, but rather quickly deposit to the bottom. The raw materials accumulated at the bottom will cause the composition of the entire mixed material to be uneven, and will also cause a large difference in the content of the curing agent in the mixed samples taken from different parts inside the device. At the same time, the raw materials accumulated at the bottom will increase the operating load of the device because the stirring paddle needs to overcome greater resistance to flip these accumulated materials, which will lead to an increase in the power consumption of the motor.

[0005] 3. In addition, both fly ash and cement have relatively small particle sizes. Fly ash is the fine particulate residue after fuel combustion, and cement is also a powdery substance. Their particle sizes are small and the binding force between particles is relatively weak, with a certain degree of looseness. Therefore, when these materials are input into the equipment, due to the flow of the materials and the air flow disturbance inside the equipment, it is very easy for some fine particles to be lifted up and thus float upward. Due to the floating of some particles, in order to achieve an ideal mixing effect, the mixing time needs to be extended. The fly ash and cement that could originally be mixed within a certain time under normal circumstances become more complex in the mixing process due to the floating phenomenon and require more time to ensure that all fly ash and cement can be fully mixed. Moreover, the floating fly ash and cement particles will adsorb on the inner wall, top and other parts of the equipment, and these adsorbed particles are very difficult to participate in the mixing process again, resulting in material loss. As the number of mixing times increases, this material loss will gradually accumulate, which not only affects the mixing cost but also the quality of the final product.

[0006] In view of this, the present invention proposes a low-consumption and high-production-capacity continuous fly ash mixer to make up for and improve the deficiencies of the existing technology. Summary of the Invention

[0007] To solve the above technical problems, the present invention provides a low-consumption and high-production-capacity continuous fly ash mixer to solve the technical problems raised in the above background technology.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A low-consumption and high-production-capacity continuous fly ash mixer, including a machine platform base, above which a mixing chamber body is installed. Inside the mixing chamber body, an inclined gap mixing mechanism is provided, and the inclined gap mixing mechanism is used to penetrate and convey materials in an inclined manner to achieve unitized mixing.

[0009] Further, the inclined gap mixing mechanism includes a new type of feeding cylinder installed inside the mixing chamber body. A spiral conveying shaft is fixedly connected inside the new type of feeding cylinder. A group of equal-height discharge pipes is rotatably connected below the new type of feeding cylinder. A branch liquid delivery pipe is communicated above the new type of feeding cylinder. Discharge holes are opened at the positions corresponding to the group of equal-height discharge pipes and the branch liquid delivery pipe above and below the new type of feeding cylinder, and the size ratios of the discharge holes respectively correspond to and match the output end size ratios of the group of equal-height discharge pipes and the branch liquid delivery pipe.

[0010] Further, the lengths of the output ends in the group of equal-height discharge pipes are distributed in a decreasing form from left to right, and all the output ends in the group of equal-height discharge pipes are located on the same horizontal plane.

[0011] Furthermore, the interior of the output end of the equal-height row of pipes can be divided into upper and lower regions. The upper region is cylindrical, and the lower region is funnel-shaped. A serrated clip group is installed in the upper region of the output end of the equal-height row of pipes, and the inner wall of the lower region of the output end of the equal-height row of pipes is corrugated.

[0012] Furthermore, the serrated clip group as a whole is composed of no less than four serrated plates, and elastic cables are fixedly connected to the side walls of the serrated plates. The serrated clip group is movably connected to the equal-height row of pipes through the elastic cables.

[0013] Furthermore, the lengths of the output ends in the branch infusion pipes are distributed in an increasing form from left to right, and liquid additives are stored inside the branch infusion pipes.

[0014] Furthermore, an inclined wall water guiding and dust suppressing mechanism is symmetrically arranged inside the mixing chamber body. The inclined wall water guiding and dust suppressing mechanism is used for continuously conveying water to form a water film to suppress the dispersion of dust and mixed materials. The inclined wall water guiding and dust suppressing mechanism includes main flow plates symmetrically and fixedly connected to the side walls of the mixing chamber body, and convex-bottom cylinders are installed above the main flow plates.

[0015] Furthermore, the main flow plates are overall elliptical in shape, the two ends of the main flow plates are rounded, the upper and lower surfaces of the main flow plates are both frosted, and the main flow plates are overall composed of titanium dioxide ceramic materials.

[0016] Furthermore, the bottom of the convex-bottom cylinder is convex in an arc shape, composed of two incomplete arcs connected, and the protruding vertex in the convex-bottom cylinder is located at the exact center position inside the convex-bottom cylinder.

[0017] Furthermore, a driving module is installed on the side wall of the mixing chamber body. The driving module mainly includes a spiral stirring shaft, a driving motor, and a reciprocating motor. The spiral stirrers in the driving module are symmetrically distributed inside the mixing chamber body. Disturbing ash bins are fixedly connected to the outer walls of the spiral stirring shafts. The disturbing ash bins are overall shovel-shaped bodies. A feeding stirring shaft is installed directly below the center of the threaded stirring shaft. The feeding stirring is driven independently by the reciprocating motor in the driving module.

[0018] Furthermore, a discharging module is communicated with the side wall of the mixing chamber body. The discharging module is located at the bottom position of the mixing chamber body and mainly includes a gate valve. A feeding module and a water conveying module are externally connected above the mixing chamber body. The feeding module is in communication with the new feeding cylinder, and the water conveying module is in communication with the main flow plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In order to improve the problem of uneven distribution of raw materials inside the equipment, the present device introduces a through-type inclined conveying pipeline, whose output end to the end is inclined from high to low. By using the method of making up the distance difference with the height difference, it ensures that the fly ash can be evenly distributed to each area inside the equipment simultaneously. Moreover, during the rotation of the conveying pipeline, feeding is achieved through the surface notch, and additives are added in different areas synchronously to ensure the full mixing of fly ash and additives. Through this unitized mixing mode, the material conveying in the whole mixing process is decomposed into multiple small mixing units, which not only improves the mixing efficiency but also ensures the uniformity of mixing. Each feeding area is equivalent to an independent mixing unit, which also makes the contact between fly ash and additives more sufficient and the reaction more complete.

[0020] Particularly importantly, the design of the through-type inclined conveying pipeline effectively reduces the retention of fly ash on the cross-section of the equipment by optimizing the conveying path and reducing the wall friction force, improving the conveying efficiency and uniformity of fly ash. Moreover, this method enables the equipment to continuously convey materials while cooperating with intermittent feeding, meeting the requirement of unitized mixing of the stirring shaft inside the equipment. This design method not only improves the processing efficiency of the equipment but also enhances the control ability of the equipment over the mixing state of fly ash and additives, avoiding the high-load operation state of the spiral stirring shaft.

[0021] Compared with the feeding method in the prior art, the present device avoids the accumulation of fly ash near the feeding end and the lag in the arrival of fly ash far from the feeding end, which helps to establish a uniform material distribution state at the beginning of the equipment operation, laying a good foundation for subsequent mixing. At the same time, adopting the unitized mixing mode makes the distribution of fly ash on the cross-section of the equipment more uniform, overcoming the problem of uneven distribution caused by the conveying difference of the spiral shaft.

[0022] The present device adopts the upper and lower partition design inside the output end of the equal-height row pipe group, and combines the sawtooth clip group and the corrugated inner wall structure, which also has the following advantages: First, the sawtooth clip group installed in the upper area, its multiple sharp tooth-like structures can contact the material more deeply during the material discharge process, not only enhancing the interaction force between the material and the inner wall of the pipeline but also having a stronger crushing and dispersing effect on the material, which helps to break the lumps and aggregates in the material, ensuring the fluidity of the material and providing better conditions for subsequent processing procedures.

[0023] Second, the lower area adopts the corrugated inner wall design, and its continuous wave crest and wave trough structures provide a dynamic redistribution environment for the material. For some fly ash that is relatively loose but prone to uneven accumulation in the pipeline, the wavy inner wall can redistribute the material under the action of the wave crest and wave trough, avoiding the blockage problem caused by excessive local accumulation and ensuring the smooth flow of the material.

[0024] Thirdly: This structural design can adapt to materials of different properties and states. Whether it is severely caked materials or loose and easily piled-up fly ash, good treatment can be achieved through the effective action of the serrated clamp group and the corrugated inner wall, thereby enhancing the versatility and adaptability of the equipment.

[0025] (2) Through the cooperative design between the main flow plate and the new material conveying cylinder in this device, two symmetrical guiding surfaces are formed inside the equipment. When conveying water inside the equipment, the water flow flows along the surface of the main flow plate and is affected by the comprehensive effects of the elliptical plate characteristics, fillet treatment, frosting treatment, and hydrophilic material characteristics of the main flow plate, enabling the water flow to continue flowing along the lower arc surface of the elliptical plate until it falls downward at the concave point position of the lower arc surface, achieving a full-coverage spraying form. This spraying method not only ensures sufficient contact between water and materials but also improves the uniformity of water spraying.

[0026] Particularly importantly, by forming a water film to disperse the upward floating trend of soot, water can increase the weight of the soot, making it easier to settle. At the same time, the presence of the water film blocks the upward movement path of the soot, further reducing the floating phenomenon, which helps to shorten the mixing time and improve the mixing efficiency.

[0027] Compared with the prior art, the designed water conveyance flow mode of this device improves the mixing process that was originally disrupted due to particle floating, greatly improves the mixing efficiency, enables fly ash and cement to achieve an ideal mixing effect in a shorter time, helps to improve production efficiency, reduce energy consumption and the operating cost of the equipment, and, moreover, avoids the adsorption of floating fly ash and cement particles on the inner wall, top, etc. of the equipment, thereby improving the internal environment of the equipment. At the same time, the reduction of material adsorption means that the cleaning cycle inside the equipment can be extended, so the frequency and difficulty of equipment maintenance are reduced, which helps to increase the service life of the equipment, reduce the equipment maintenance cost, and improve the overall operating reliability of the equipment.

[0028] (3) To address the problems in the prior art such as raw material settling at the bottom, increased equipment load, and increased motor power consumption, this device has the following benefits and improvements through the design of improving the internal spiral stirring shaft of the equipment and installing a soot disturbing bin: Firstly: The soot disturbing bin is designed as a shoveled arc-shaped bin as a whole, which can effectively collect the coarser granular materials deposited at the bottom of the equipment. As the spiral shaft rotates, the soot disturbing bin makes a circular motion. When the bin body rotates from below to above the vertex, the materials inside the bin body are re-thrown out under the combined influence of rotational centrifugal force and gravity and fall on the top of the materials inside the equipment. This process promotes the tumbling and redistribution of the materials, helps to achieve uniform mixing of the materials, and reduces the uneven mixing phenomenon caused by particle size differences.

[0029] Second: Through the storage and ejection functions of the ash disturbing bin, the accumulation state of the materials at the bottom of the equipment is broken, the flow characteristics of the materials inside the equipment are improved, and further, the residence time of the materials inside the equipment is reduced, and the mixing efficiency is improved. At the same time, due to the design of the ash disturbing bin, the accumulation of materials at the bottom of the equipment is reduced, so that the resistance that the spiral stirring shaft needs to overcome when turning over the materials is correspondingly reduced, which further helps to reduce the power consumption of the motor, improve the energy efficiency ratio of the equipment, and thus reduce the production cost.

[0030] Third: By promoting the uniform mixing of the materials, the design of the ash disturbing bin helps to reduce the difference in the content of the curing agent in the mixed samples taken from different parts inside the equipment, and further improves the consistency of the mixed samples, ensuring the stability of the product quality.

[0031] (4) First, when the feeding stirring shaft and the threaded stirring shaft rotate in opposite directions, the stirring forces generated by the two are in opposite directions. Relying on the interlacing of the stirring forces of the two stirring shafts, the fly ash materials can fully exchange positions in the circumferential regions with different radii in the horizontal direction, so as to achieve all-round uniform mixing.

[0032] Second, the reverse rotation of the feeding stirring shaft can also directly agitate the materials at the bottom, re-involve the deposited materials into the overall mixing flow, ensure that all materials can participate in the mixing process, and improve the mixing efficiency and quality.

[0033] Finally, when the mixing is completed, the feeding stirring shaft and the threaded stirring shaft rotate in the same direction, which makes the stirring forces generated by the two stirring shafts in the same direction, forming a unified material flow direction in the mixing cylinder. Relying on this unified flow direction, the materials in these regions can be smoothly pushed to the discharge port, improving the utilization rate of the materials and reducing the workload of cleaning the equipment.

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] It should be noted that the structures and working principles of the above-mentioned devices such as the machine base 1, the mixing bin body 11, the drive module 12, and the discharging module 13 belong to the prior art and will not be elaborated here.

[0049] Embodiment 1: Please refer to Figure 1 and Figure 2 As shown, a low-consumption and high-production continuous fly ash mixer includes a machine base 1, and a mixing bin body 11 is installed above the machine base 1. It is characterized in that: an inclined gap mixing mechanism 2 is arranged inside the mixing bin body 11, and the inclined gap mixing mechanism 2 is used to penetrate and convey materials in an inclined manner to achieve unitized mixing.

[0050] It should be noted that a driving module 12 is installed on the side wall of the mixing bin 11. The driving module 12 mainly includes a spiral stirring shaft, a driving motor, and a reciprocating motor. The spiral stirrers in the driving module 12 are symmetrically distributed inside the mixing bin 11. The side wall of the mixing bin 11 is communicated with a discharging module 13. The discharging module 13 is located at the bottom of the mixing bin 11 and mainly includes a gate valve. A feeding module and a water supply module are externally connected above the mixing bin 11. The feeding module is in communication with the new feeding cylinder 21, and the water supply module is in communication with the main flow plate 31.

[0051] Specifically, during the fly ash treatment process, several materials such as fly ash, cement, additives, and water usually need to be added inside the equipment. Fly ash is the main substance to be treated. Cement is used as a gelling material to solidify fly ash. Additives are used to improve the mixing process or enhance the solidification effect. Water is necessary for the hydration reaction of cement and for adjusting the state of materials during the mixing process. First, fly ash is added to the mixing bin 11 to provide a basis for the addition of subsequent materials. Then, additives are added through the branch infusion pipe 25. Next, cement is added. Cement is usually added to the mixing bin 11 in powder form. Since the main function of cement is to solidify fly ash, cement is added after the additives, which can not only make cement better wrap the fly ash particles but also prevent premature hydration of cement from affecting the mixing effect. Finally, water is added through the convex-bottom cylinder 32.

[0052] Please refer to Figures 2 to 6 As shown, the inclined-gap mixing mechanism 2 includes a new feeding cylinder 21 installed inside the mixing bin 11. A spiral conveying shaft 22 is fixedly connected inside the new feeding cylinder 21. An equal-height row of pipes group 23 is rotatably connected below the new feeding cylinder 21. A branch infusion pipe 25 is communicated above the new feeding cylinder 21.

[0053] It should be noted that discharge holes are provided at the positions corresponding to the equal-height row of pipes group 23 and the branch infusion pipe 25 above and below the new feeding cylinder 21, and the size ratios of the discharge holes respectively correspond to and match the size ratios of the output ends of the equal-height row of pipes group 23 and the branch infusion pipe 25. The lengths of the output ends in the equal-height row of pipes group 23 are distributed in a decreasing form from left to right, and the output ends in the equal-height row of pipes group 23 are all located on the same horizontal plane. The output ends of the equal-height row of pipes group 23 can be divided into upper and lower regions inside. The upper region is cylindrical, and the lower region is funnel-shaped. Serrated clip groups 24 are installed in the upper regions of the output ends of the equal-height row of pipes group 23, and the inner walls of the lower regions of the output ends of the equal-height row of pipes group 23 are all corrugated. The whole serrated clip group 24 is composed of no less than four serrated plates combined, and elastic cables are fixedly connected to the side walls of the serrated plates. The serrated clip group 24 is movably connected to the equal-height row of pipes group 23 through the elastic cables. The lengths of the output ends in the branch infusion pipe 25 are distributed in an increasing form from left to right, and liquid additives are stored inside the branch infusion pipe 25.

[0054] Specifically, when fly ash materials are conveyed into the interior of the new material conveying cylinder 21, first, according to the principle of the gravitational potential energy formula, a penetrating and inclined new material conveying cylinder 21 is arranged inside the mixing bin 11, and the output end to the end is inclined from high to low. The existence of this height difference enables the fly ash materials to have different gravitational potential energies in the pipeline. Moreover, in the inclined new material conveying cylinder 21, the height difference will cause the generation of a pressure difference. According to the principle of hydrostatics, this pressure difference will push the materials to flow inside the new material conveying cylinder 21. For the entire interior of the new material conveying cylinder 21, the pressure differences in each spaced area are related to the height difference. Since the pipeline is inclined, the height differences in each area can be adjusted so that the pressure differences are relatively evenly distributed inside the pipeline. At the same time, in cooperation with the regular rotation of the new material conveying cylinder 21 itself, it discharges materials when encountering a notch. Therefore, the rotational discharging of this device and the effect of the height difference cooperate with each other, enabling the height difference to provide the basic discharging power for the materials, while the rotational discharging further controls the discharging process. In each area, due to the height difference ensuring that the materials have a tendency to move downward, when discharging by rotation, the materials can be continuously released into the mixing bin 11 according to the opened discharge ports, thereby achieving the effect of simultaneous discharging in each area and uniform discharging within a certain range. Among them, the new material conveying cylinder 21 is driven to rotate by an externally connected conversion part, and the conversion part can be specifically selected and used according to cost. First: directly controlled by a micro motor. Second: the parallel eccentric coupling is controlled by a driving motor inside the equipment.

[0055] Example 2: On the basis of Example 1, please refer to Figures 7 to 10 As shown, inclined wall water guiding and dust suppressing mechanisms 3 are symmetrically arranged inside the mixing bin 11. The inclined wall water guiding and dust suppressing mechanisms 3 are used for continuously conveying water to form a water film to suppress the dispersion of dust and mixed materials. The inclined wall water guiding and dust suppressing mechanisms 3 include main flow plates 31 symmetrically and fixedly connected to the side walls of the mixing bin 11, and convex bottom cylinders 32 are installed above the main flow plates 31.

[0056] It should be noted that the main flow plates 31 are overall elliptical in shape, both ends of the main flow plates 31 are rounded, both the upper and lower surfaces of the main flow plates 31 are frosted, and the main flow plates 31 are entirely composed of titanium dioxide ceramic materials. The bottom of the convex bottom cylinder 32 is convex in an arc shape, composed of two incomplete arcs connected, and the vertex of the convex part in the convex bottom cylinder 32 is located at the exact center position inside the convex bottom cylinder 32.

[0057] Specifically, when water is discharged from the convex-bottom cylinder 32 and flows toward both sides along the surface of the main flow plate 31, since the two ends of the main flow plate 31 are rounded, it helps the water flow smoothly transition from the upper arc surface of the ellipse to both sides. The rounded corners reduce the sudden turning of the water flow at the ends, enabling the water flow to change direction more smoothly and avoiding splashing or detaching from the surface of the main flow plate 31 due to sharp turning. Moreover, the frosting treatment on the upper and lower arc surfaces of the main flow plate 31 increases the surface roughness. For the water flow, this increases the frictional force between the water and the surface of the main flow plate 31. When the water flow moves on the upper arc surface, this frictional force helps keep the water flow on the surface of the main flow plate 31 instead of easily slipping or splashing out. When the water flow reaches the lower arc surface after passing through the rounded corner edges at both ends, due to the frictional force generated by the frosting treatment, the water flow is more inclined to continue flowing along the lower arc surface. At the same time, since the discharged water flow rate is slow, surface tension plays a relatively more important role in the movement of the water flow. Surface tension will make the water try to keep in contact with the surface of the main flow plate 31 and attempt to "pull" the water on the main flow plate 31. Due to the slow water flow speed, the inertia of the water flow itself is small and is not sufficient to overcome the combined action of surface tension and the frictional force on the surface of the main flow plate 31 to easily detach from the surface of the main flow plate 31. Finally, combined with the fact that the main flow plate 31 is entirely composed of the hydrophilic material titanium dioxide ceramic, therefore, under the combined action of the above-mentioned characteristics of the main flow plate 31, namely rounded corner treatment, frosting treatment, its own material characteristics, and slower water flow rate, the water flow will continue to flow along the lower arc surface of the main flow plate 31 until it falls downward at the concave point position of the lower arc surface. Although when the water flow has not reached the concave point and drips downward in the form of water droplets, it can also achieve the purpose of carrying fly ash downward. By forming a water film to disperse the upward floating trend of the soot, the water can increase the weight of the soot, making it easier to settle. At the same time, the presence of the water film blocks the upward movement path of the soot, further reducing the floating phenomenon. This helps shorten the mixing time and improve the mixing efficiency.

[0058] It should be noted that the outer walls of the spiral stirring shafts are fixedly connected with ash disturbing bins 33, and the ash disturbing bins 33 are in the shape of a shovel-shaped bin as a whole.

[0059] Specifically, when the ash disturbing bin 33 rotates synchronously with the spiral stirring shaft in the driving module 12, first, by combining the special shape of the bin body with the rotation of the spiral stirring shaft, the stress state of the bottom material is changed. When the spiral stirring shaft rotates, the ash disturbing bin 33 acts like a shovel, shoveling up and collecting the bottom material into the bin body. When an object moves in a circular motion, according to Newton's second law, the object will be subjected to a centripetal force. And in a rotating non-inertial reference frame, the object will feel a virtual force that is equal in magnitude and opposite in direction to the centripetal force, which is the centrifugal force. Therefore, when the ash disturbing bin 33 at the bottom of the spiral stirring shaft moves in a circular motion with the spiral stirring shaft, the material in the bin body also moves in a circular motion. As the bin body rotates from the bottom to above the vertex, the radius gradually increases, and the centrifugal force also gradually increases. At this time, combined with the influence of the gravity of the material, when the bin body rotates to above the vertex, the direction of the centrifugal force is outward along the radius of the circular motion, and the direction of the gravity is vertically downward. The combined action of these two forces makes the material tend to move downward and outward, so as to overcome the resistance such as the friction between the material and the bin body, and be thrown out of the bin body, thereby realizing the uniform mixing of the material and reducing the uneven mixing phenomenon caused by particle size differences.

[0060] It should be noted that a material conveying and stirring shaft is installed directly below the center of the threaded stirring shaft, and the material conveying and stirring is independently driven by a reciprocating motor in the driving module.

[0061] Specifically, when the device is in the process of mixing raw materials, at this time, the material conveying and stirring shaft will rotate in the opposite direction to the upper threaded stirring shaft, so as to circulate and fully mix the fly ash material inside the device, and can also prevent some fly ash materials from depositing at the bottom of the device. Secondly, when the mixing is completed and the device is in the process of discharging materials, the material conveying and stirring shaft will rotate in the same direction as the threaded stirring shaft, so as to facilitate the discharging process inside the device.

[0062] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
