Description
Technical Field
[0001] This invention relates to the field of fly ash mixing technology, specifically to a low-consumption, high-capacity continuous fly ash mixer. Background Technology
[0002] Existing fly ash mixers are devices specifically designed for fly ash treatment. They continuously receive fly ash and other materials as input and simultaneously output pre-mixed materials. Fly ash is typically a solid waste generated during combustion processes, and fly ash mixers can continuously process it to meet the requirements of subsequent treatment or reuse. However, existing technologies still have the following drawbacks in practical use: 1. In existing technologies, the fly ash conveyor is generally installed at one end of the equipment. Therefore, fly ash can only enter the equipment from this specific location. In the initial stage of equipment startup, fly ash will first accumulate in the area near the feed end. When the subsequent spiral agitator shaft starts to rotate, the fly ash near the feed inlet will be stirred first. However, since subsequent fly ash continues to enter from this single feed inlet, the newly entered fly ash will form a high concentration in some areas, while the fly ash in areas far from the feed inlet arrives relatively late, resulting in an uneven initial distribution of fly ash inside the equipment.
[0003] Furthermore, although the rotating spiral agitator can push fly ash to other areas of the equipment, the conveying efficiency of the spiral agitator varies at different locations. Fly ash near the center of the spiral agitator experiences a greater pushing force and can move to a distance more quickly, while fly ash near the inner wall of the equipment moves relatively slowly due to the influence of wall friction. Therefore, when the spiral agitator rotates, fly ash located between the edge of the spiral blades and the inner wall of the equipment will be stuck, resulting in uneven distribution of fly ash on the cross-section of the equipment.
[0004] 2. At the same time, due to the differences in particle size in the raw materials, coarser particles, due to their relatively large mass, are more likely to settle to the bottom of the equipment under the influence of gravity during the mixing process. For example, fly ash contains some larger particles that are not completely burned. Under the stirring action of the spiral stirring shaft, these particles are not easily turned over as easily as the fine fly ash particles, but instead settle to the bottom more quickly. The raw materials accumulated at the bottom will cause uneven composition of the entire mixture and result in a large difference in the content of curing agent in the mixed samples taken from different parts of the equipment. At the same time, the raw materials accumulated at the bottom will increase the operating load of the equipment, because the stirring blades need to overcome greater resistance to turn over these accumulated materials, which will lead to an increase in the power consumption of the motor.
[0005] 3. Furthermore, both fly ash and cement have small particle sizes. Fly ash is the fine particulate residue after fuel combustion, and cement is also a powdery substance. Their small particle size and relatively weak interparticle bonding result in a certain degree of looseness. Therefore, when these materials are fed into the equipment, the flow of materials and the airflow disturbance inside the equipment can easily cause some fine particles to be lifted and dispersed upwards. Due to the dispersion of some particles, the mixing time needs to be extended to achieve the ideal mixing effect. Fly ash and cement that could normally be mixed within a certain time becomes more complicated due to the dispersion phenomenon, requiring more time to ensure that all fly ash and cement are fully mixed. Moreover, the dispersed fly ash and cement particles will adhere to the inner wall, top, and other parts of the equipment. These adsorbed particles are difficult to re-participate in the mixing process, leading to material loss. As the number of mixing cycles increases, this material loss will gradually accumulate, affecting not only the mixing cost but also the quality of the final product.
[0006] Therefore, in view of this, the present invention proposes a low-consumption, high-capacity continuous fly ash mixer to make up for and improve the shortcomings of the prior art. Summary of the Invention
[0007] To address the aforementioned technical problems, this invention provides a low-consumption, high-capacity continuous fly ash mixer, thereby resolving the technical issues raised in the background section.
[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a low-consumption, high-capacity continuous fly ash mixer, including a machine base, a mixing chamber installed above the machine base, and an inclined gap mixing mechanism provided inside the mixing chamber. The inclined gap mixing mechanism is used for through inclined conveying of materials to achieve unitized mixing.
[0009] Furthermore, the inclined gap mixing mechanism includes a conveying cylinder installed inside the mixing chamber. A spiral conveying shaft is fixedly connected inside the conveying cylinder. A height-equalizing pipe assembly is rotatably connected below the conveying cylinder. A branch infusion pipe is connected above the conveying cylinder. Drainage holes are provided above and below the conveying cylinder at positions corresponding to the height-equalizing pipe assembly and the branch infusion pipe. The size ratio of the drainage holes corresponds to the size ratio of the output ends of the height-equalizing pipe assembly and the branch infusion pipe.
[0010] Furthermore, the lengths of the output ends in the equal-height pipe group decrease sequentially from left to right, and all the output ends in the equal-height pipe group are located on the same horizontal plane.
[0011] Furthermore, the output end of the equal-height pipe array can be divided into upper and lower regions. The upper region is cylindrical and the lower region is funnel-shaped. The upper region of the output end of the equal-height pipe array is equipped with a sawtooth clamp assembly, and the inner wall of the lower region of the output end of the equal-height pipe array is corrugated.
[0012] Furthermore, the sawtooth clamp assembly is composed of no less than four sawtooth plates, and the side walls of the sawtooth plates are all fixedly connected with elastic cables. The sawtooth clamp assembly and the equal-height pipe arrangement assembly are movably connected by elastic cables.
[0013] Furthermore, the length of the output end in the branch infusion tube increases sequentially from left to right, and the branch infusion tube contains liquid additives.
[0014] Furthermore, the mixing chamber is symmetrically equipped with inclined wall water guiding and dust suppression mechanisms. These mechanisms are used to continuously supply water to form a water film to suppress the dispersion of the mixed materials. The inclined wall water guiding and dust suppression mechanisms include main flow plates that are symmetrically fixed to the side walls of the mixing chamber, and each main flow plate is equipped with a convex bottom cylinder.
[0015] Furthermore, the main plate is elliptical in shape, with rounded corners at both ends, and both the top and bottom surfaces are frosted. The main plate is composed entirely of titanium dioxide ceramic material.
[0016] Furthermore, the bottom of the convex bottom cylinder is arc-shaped and is composed of two incomplete arcs connected together, and the apex of the convex bottom cylinder is located at the exact center inside the convex bottom cylinder.
[0017] Furthermore, a drive module is installed on the side wall of the mixing chamber. The drive module mainly includes a spiral stirring shaft, a drive motor, and a reciprocating motor. The spiral stirring shafts in the drive module are symmetrically distributed inside the mixing chamber. A dust-dispersing hopper is fixedly connected to the outer wall of each spiral stirring shaft. The dust-dispersing hopper is shovel-shaped. A material conveying stirring shaft is installed directly below the center of the spiral stirring shaft. The material conveying and stirring are driven separately by the reciprocating motor in the drive module.
[0018] Furthermore, the side wall of the mixing chamber is connected to a discharge module, which is located at the bottom of the mixing chamber and mainly includes a gate valve. The upper part of the mixing chamber is connected to a material conveying module and a water conveying module. The material conveying module is connected to the material conveying cylinder, and the water conveying module is connected to the main flow plate.
[0019] Compared with the prior art, the beneficial effects of the present invention are: (1) In order to improve the problem of uneven distribution of raw materials inside the equipment, this device introduces a through-type inclined conveying pipe, so that the output end to the end is inclined from high to low. The method of using the height difference to make up for the distance difference ensures that the fly ash can be distributed evenly to various areas inside the equipment at the same time. In addition, during the rotation of the conveying pipe, the material is fed through the surface notch, and additives are added in different areas at the same time to ensure that the fly ash and additives are fully mixed. Through this unitized mixing mode, the material conveying of the entire 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 fly ash and additives more fully contacted and the reaction more complete.
[0020] Most importantly, the design of the through-type inclined conveying pipe effectively reduces the retention of fly ash on the cross-section of the equipment by optimizing the conveying path and reducing wall friction, thereby improving the conveying efficiency and uniformity of fly ash. Furthermore, this method allows the equipment to continuously convey materials while simultaneously feeding intermittently, meeting the unitized mixing requirements of the internal stirring shaft. This design not only improves the processing efficiency of the equipment but also enhances its ability to control the mixing state of fly ash and additives, preventing the spiral stirring shaft from operating under high load.
[0021] Compared with the feeding methods in the existing technology, this device avoids the accumulation of fly ash near the feed end and the delayed arrival of fly ash far from the feed end. It helps to establish a uniform material distribution at the beginning of equipment operation, laying a good foundation for subsequent mixing. At the same time, the unitized mixing mode makes the fly ash distribution on the cross-section of the equipment more uniform, overcoming the problem of uneven distribution caused by the difference in screw shaft conveying.
[0022] This device adopts an upper and lower partition design inside the output end of the equal-height pipe assembly, combined with a sawtooth clamp assembly and a corrugated inner wall structure, which has the following advantages: Firstly, the sawtooth clamp assembly installed in the upper area has multiple sharp teeth that can make deeper contact with the material during the material discharge process. This not only enhances the interaction force between the material and the inner wall of the pipe, but also produces a stronger crushing and dispersing effect on the material. This helps to break up lumps and agglomerates in the material, ensures the flowability of the material, and provides better conditions for subsequent processing steps.
[0023] Secondly, the lower area adopts a corrugated inner wall design. Its continuous crests and troughs provide a dynamic redistribution environment for materials. For some loose fly ash that is prone to uneven accumulation in the pipe, the corrugated inner wall can redistribute the material under the action of crests and troughs. This avoids the blockage problem caused by excessive local accumulation and ensures the smooth flow of materials.
[0024] Thirdly, the structural design can adapt to materials of different properties and states. Whether it is agglomerated material or loose fly ash that is easy to accumulate, it can be well treated through the effective action of the sawtooth clamp group and the corrugated inner wall, thereby enhancing the versatility and adaptability of the equipment.
[0025] (2) By introducing the cooperation design between the main plate and the conveying cylinder, the device forms two symmetrical guide surfaces inside the equipment. When water is conveyed inside the equipment, the water flows along the surface of the main plate and is affected by the combined effects of the characteristics of the elliptical plate, the rounded corner treatment, the frosted treatment and the hydrophilic material properties of the main plate. This allows the water to continue to flow along the lower arc surface of the elliptical plate until it falls down at the concave point of the lower arc surface, achieving a full-coverage spray. This spraying method not only ensures full contact between water and materials, but also improves the uniformity of water spraying.
[0026] Most importantly, the water film breaks up the tendency of the soot to float upwards. Water increases the weight of the soot, making it easier for it to settle. At the same time, the presence of the water film blocks the upward movement of the soot, further reducing the floating phenomenon. This helps to shorten the mixing time and improve the mixing efficiency.
[0027] Compared to existing technologies, the water flow design of this device improves the mixing process, which was previously disrupted by particle dispersion, significantly increasing mixing efficiency. This allows fly ash and cement to achieve the desired mixing effect in a shorter time, helping to improve production efficiency, reduce energy consumption and equipment operating costs. Furthermore, it prevents dispersed fly ash and cement particles from adhering to the inner walls and top of the equipment, thus improving the internal environment. At the same time, the reduction in material adsorption means that the internal cleaning cycle can be extended, thereby reducing the frequency and difficulty of equipment maintenance, helping to extend the service life of the equipment, reduce maintenance costs, and improve the overall operational reliability of the equipment.
[0028] (3) In order to improve the problems of raw material settling at the bottom, increased equipment load and increased motor power consumption in the existing technology, this device has brought the following benefits and improvements by improving the design of the internal spiral stirring shaft and installing the dust hopper: Firstly, the dust hopper is designed as a shovel-shaped arc-shaped hopper, which can effectively collect the coarser particles deposited at the bottom of the equipment. As the spiral shaft rotates, the dust hopper makes a circular motion. When the hopper rotates from the bottom to the top, the material inside the hopper is thrown out again under the combined influence of the centrifugal force and gravity and falls on the top of the material inside the equipment. This process promotes the turning and redistribution of the material, which helps to achieve uniform mixing of the material and reduces the uneven mixing caused by particle size differences.
[0029] Secondly, the ash-discharging hopper breaks up the accumulation of materials at the bottom of the equipment, improves the flow characteristics of materials inside the equipment, reduces the residence time of materials inside the equipment, and improves mixing efficiency. At the same time, because the design of the ash-discharging hopper reduces the accumulation of materials at the bottom of the equipment, the resistance that the spiral mixing shaft needs to overcome when turning the material is reduced accordingly, which helps to reduce the power consumption of the motor, improve the energy efficiency ratio of the equipment, and thus reduce production costs.
[0030] Thirdly, by promoting uniform mixing of materials, the design of the ash-dispersing hopper helps reduce the difference in curing agent content in mixed samples taken from different parts of the equipment, thereby improving the consistency of the mixed samples and ensuring the stability of product quality.
[0031] (4) First, when the conveying mixing shaft and the threaded mixing shaft rotate in opposite directions, the mixing forces generated by the two shafts are opposite in direction. Relying on the interlacing of the mixing forces of the two mixing shafts, the fly ash material can fully exchange positions in the circumferential areas of different radii in the horizontal direction, thereby achieving all-round uniform mixing.
[0032] Secondly, the reverse rotation of the conveying and stirring shaft can directly agitate the bottom material, re-entraining the deposited material into the overall mixing flow, ensuring that all materials can participate in the mixing process, thus improving the efficiency and quality of mixing.
[0033] Finally, after mixing is complete, the conveying agitator shaft and the threaded agitator shaft rotate in the same direction. This makes the agitation force generated by the two agitator shafts align, creating a unified material flow direction within the mixing drum. Relying on this unified flow direction, the material in these areas can be smoothly pushed to the discharge port, improving material utilization and reducing the workload of cleaning equipment.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0048] It should be noted that the structure and working principle of the above-mentioned machine base 1, mixing chamber 11, drive module 12, discharge module 13 and other components are existing technologies and will not be described in detail here.
[0049] Example 1: Please refer to Figure 1 and Figure 2 As shown, a low-consumption, high-capacity continuous fly ash mixer includes a machine base 1 and a mixing chamber 11 installed above the machine base 1. The mixer is characterized in that an inclined gap mixing mechanism 2 is provided inside the mixing chamber 11. The inclined gap mixing mechanism 2 is used for through inclined conveying of materials to achieve unitized mixing.
[0050] It should be noted that a drive module 12 is installed on the side wall of the mixing chamber 11. The drive module 12 mainly includes a spiral stirring shaft, a drive motor and a reciprocating motor. The spiral stirring shaft in the drive module 12 is symmetrically distributed inside the mixing chamber 11. The side wall of the mixing chamber 11 is connected to a discharge module 13, which is located at the bottom of the mixing chamber 11. The discharge module 13 mainly includes a gate valve. A material conveying module and a water conveying module are connected to the top of the mixing chamber 11. The material conveying module is connected to the material conveying cylinder 21, and the water conveying module is connected to the main flow plate 31.
[0051] Specifically, in the fly ash treatment process, the equipment usually needs to add fly ash, cement, additives and water. Fly ash is the main substance to be treated. Cement is used as a cementing material to solidify the fly ash. Additives are used to improve the mixing process or improve the solidification effect. Water is necessary for the cement hydration reaction and for adjusting the state of the materials during the mixing process. First, fly ash is added to the mixing chamber 11 to provide a basis for the addition of subsequent materials. Then, additives are added through the branch infusion pipe 25, followed by cement. Cement is usually added to the mixing chamber 11 in powder form. Since the main function of cement is to solidify fly ash, cement is added after the additives. This allows the cement to better coat the fly ash particles and also prevents the cement from hydrating too early and 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 conveying cylinder 21 installed inside the mixing chamber 11. A spiral conveying shaft 22 is fixedly connected inside the conveying cylinder 21. A height equalization pipe assembly 23 is rotatably connected below the conveying cylinder 21. A branch infusion pipe 25 is connected above the conveying cylinder 21.
[0053] It should be noted that drainage holes are provided above and below the feed cylinder 21 at positions corresponding to the equal-height pipe assembly 23 and the branch infusion pipe 25, and the size ratio of the drainage holes corresponds to the size ratio of the output ends of the equal-height pipe assembly 23 and the branch infusion pipe 25, respectively. The length of the output ends in the equal-height pipe assembly 23 decreases from left to right, and all output ends in the equal-height pipe assembly 23 are located on the same horizontal plane. The internal structure of the output end of the equal-height pipe assembly 23 can be divided into upper and lower regions. The upper region is cylindrical, and the lower region is cylindrical. The area is funnel-shaped. The upper area of the output end of the equal height tube group 23 is equipped with a sawtooth clamp group 24, and the lower inner wall of the output end of the equal height tube group 23 is corrugated. The sawtooth clamp group 24 is composed of no less than four sawtooth plates, and the side walls of the sawtooth plates are fixedly connected with elastic cables. The sawtooth clamp group 24 and the equal height tube group 23 are movably connected by elastic cables. The length of the output end of the branch infusion tube 25 increases from left to right, and the inside of the branch infusion tube 25 stores liquid additives.
[0054] Specifically, when fly ash is conveyed into the conveying cylinder 21, firstly, based on the principle of gravitational potential energy, a through-type inclined conveying cylinder 21 is installed inside the mixing chamber 11, with the output end inclined from high to low. This height difference causes the fly ash to have different gravitational potential energies within the pipe. Furthermore, within the inclined conveying cylinder 21, this height difference leads to a pressure difference. According to the principles of fluid statics, this pressure difference propels the material to flow within the conveying cylinder 21. For the entire conveying cylinder 21, the pressure difference in each interval area is related to the height difference. Because the pipe is inclined, the height difference in each area can be adjusted to ensure a relatively uniform distribution of pressure difference within the pipe. The material feeding cylinder 21 rotates regularly and discharges material when it encounters a gap. Therefore, the rotational feeding and the height difference work together to provide the basic feeding power for the material. The rotational feeding further controls the feeding process. In each area, the height difference ensures that the material has a downward movement tendency. When rotating the feeding cylinder, the material can be continuously released into the mixing chamber 11 according to the opened discharge port, thereby achieving the effect of simultaneous feeding in each area and uniform feeding within a certain range. The material feeding cylinder 21 is driven to rotate by an external conversion component. The specific conversion component can be selected according to cost. First, it can be directly controlled by a micro motor. Second, it can be controlled by a parallel eccentric coupling driven by an internal drive motor.
[0055] Example 2: Based on Example 1, please refer to... Figures 7 to 10 As shown, the mixing chamber 11 is symmetrically equipped with inclined wall water guiding and dust suppression mechanism 3. The inclined wall water guiding and dust suppression mechanism 3 is used to continuously transport water to form a water film to suppress the dust and dispersion of the mixed materials. The inclined wall water guiding and dust suppression mechanism 3 includes a main channel plate 31 symmetrically fixedly connected to the side wall of the mixing chamber 11. A convex bottom cylinder 32 is installed above the main channel plate 31.
[0056] It should be noted that the main plate 31 is elliptical in shape, with rounded corners at both ends and frosted finish on both the top and bottom surfaces. The main plate 31 is made of titanium dioxide ceramic material. The bottom of the convex bottom cylinder 32 is arc-shaped and consists of two incomplete arcs connected together. The apex of the convex bottom cylinder 32 is located at the exact center inside the cylinder.
[0057] Specifically, when water is discharged from the convex-bottom cylinder 32 and flows to both sides along the surface of the main flow plate 31, the rounded corners at both ends of the main flow plate 31 help the water flow smoothly transition from the upper elliptical arc surface to both sides. The rounded corners reduce sudden changes in water flow at the ends, allowing the water flow to change direction more smoothly and avoiding splashing or detachment from the surface of the main flow plate 31 due to sharp changes. Furthermore, the frosted finish on the upper and lower arc surfaces of the main flow plate 31 increases surface roughness, which increases the friction between the water and the surface of the main flow plate 31. When the water flows on the upper arc surface, this friction helps keep the water on the surface of the main flow plate 31, rather than easily sliding or splashing away. When the water flows past the rounded edges at both ends and reaches the lower arc surface, the friction generated by the frosted finish also makes the water flow more inclined to continue along the lower arc surface. Simultaneously, because the discharged water flow rate is relatively slow, surface tension plays a relatively more important role in the water flow process. To maintain water's contact with the surface of the main flow plate 31 as much as possible, an attempt is made to "pull" the water onto the main flow plate 31. Due to the slow water flow speed and low inertia, the water flow is insufficient to overcome the combined effects of surface tension and friction on the surface of the main flow plate 31 and easily detach from the surface of the main flow plate 31. Finally, the main flow plate 31 is composed entirely of hydrophilic titanium dioxide ceramic. Therefore, based on the characteristics of the main flow plate 31, the combined effects of rounded corner treatment, frosted treatment, its own material properties, and the slow water flow rate, the water will continue to flow along the lower arc surface of the main flow plate 31 until it falls down at the concave point of the lower arc surface. Although the water flows down in the form of droplets before reaching the concave point, it can still achieve the purpose of carrying fly ash downwards. The formation of a water film disperses the tendency of the fly ash to float upwards. Water can increase the weight of the fly ash, making it easier for it to settle. At the same time, the presence of the water film blocks the upward movement path of the fly ash, further reducing the scattering phenomenon. This helps to shorten the mixing time and improve the mixing efficiency.
[0058] It should be noted that the outer wall of the spiral stirring shaft is fixedly connected with the ash-dispersing bin 33, which is shovel-shaped in shape.
[0059] Specifically, when the dust collection bin 33 rotates synchronously with the spiral stirring shaft in the drive module 12, firstly, by combining the special shape of the bin with the rotation of the spiral stirring shaft, the force state of the material at the bottom is changed. When the spiral stirring shaft rotates, the dust collection bin 33, like a shovel, scoops up the material at the bottom and collects it into the bin. When an object moves in a circular motion, according to Newton's second law, the object will be subjected to a centripetal force. In a rotating non-inertial reference frame, the object will experience a virtual force that is equal in magnitude and opposite in direction to the centripetal force. This is the centrifugal force. Therefore, the dust collection bin at the bottom of the spiral stirring shaft... As the hopper 33 rotates in a circular motion with the spiral stirring shaft, the material inside the hopper also rotates in a circular motion. As the hopper rotates from the bottom to the top, the radius gradually increases, and the centrifugal force also gradually increases. At this time, combined with the influence of gravity on the material, when the hopper rotates to the top, the direction of the centrifugal force is outward along the radius of the circular motion, and the direction of gravity is vertically downward. The combined effect of these two forces makes the material have a downward and outward tendency to move, thereby overcoming the frictional resistance between the material and the hopper and being thrown out of the hopper, thus achieving 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 driven separately by the reciprocating motor in the drive module.
[0061] Specifically, when the equipment is in the process of mixing raw materials, the conveying agitator shaft will rotate in the opposite direction to the upper threaded agitator shaft, thereby circulating and fully mixing the fly ash material inside the equipment, and also preventing some fly ash material from settling at the bottom of the equipment. Secondly, when the mixing is completed and the equipment is in the process of discharging, the conveying agitator shaft will rotate in the same direction as the threaded agitator shaft, thereby facilitating the discharge process inside the equipment.
[0062] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
