Description

Technical Field

[0001] The present invention relates to the technical field of filtering devices, and specifically to a hierarchical circulation filtering device for fly ash treatment. Background Art

[0002] Municipal solid waste incineration fly ash refers to the by-products that adhere to the outer wall of the waste heat boiler in the form of fly ash during the municipal solid waste incineration process or enter the flue gas purification system and are captured by the dust collector. It is generally composed of substances such as chlorides, sulfates, aluminosilicates, silicate minerals, heavy metals, and dioxins. Among them, heavy metals, dioxins, and chlorides are the main problems that currently plague the harmless treatment and resource utilization of fly ash.

[0003] Filtering devices are used to treat heavy metals, chloride ions, and dioxins in fly ash. Direct discharge will cause serious environmental pollution. The most commonly used stabilization treatment method at present is the cement solidification technology, that is, using municipal solid waste incineration fly ash as the solidification raw material to solidify with substances such as cement to form utilizable building materials. However, due to the fluidity of fly ash itself during the filtering process, substances such as cement cannot completely cover the fly ash, resulting in some fly ash that cannot be treated. When the fly ash and substances such as cement are fused, it is necessary to heat them, and the high temperature generated by heating will affect the untreated substances such as cement, causing them to solidify and reducing the overall filtering effect. It also requires workers to handle it, thus increasing the labor cost. Summary of the Invention

[0004] The purpose of the present invention is to provide a hierarchical circulation filtering device for fly ash treatment to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A hierarchical circulation filtering device for fly ash treatment, the filtering device includes a feeding component, a stirring component, a humidity maintaining component, and a sintering component. A stirring component is provided on one side of the feeding component. The stirring component is used for stirring the mixed materials. A humidity maintaining component is provided inside the stirring component. The humidity maintaining component is used for maintaining the overall humidity of the mixture. A sintering component is provided on one side of the stirring component. The sintering component is used for heating the mixture.

[0006] Specifically, the filtration device is used to treat heavy metals, chloride ions, and dioxins in fly ash. Direct discharge will cause serious environmental pollution. Among them, chloride ions are gaseous, and heavy metals and dioxins are solid. Therefore, multiple devices are used for targeted filtration of the three, resulting in excessive costs. The dumping component is used to mix and transport fly ash and cement materials. Through the adhesiveness and plasticity of cement, heavy metals and dioxins in fly ash are adsorbed and sealed. Then, the mixture of the dumping component will be transported into the stirring component. By the rotation of the stirring component, the mixing degree of the two is improved. Then, the moisture retention component in the stirring component ensures the water content in the cement so that it will not be solidified by the sintering component or humidity. When the moisture retention component sprays water mist, it will also adhere to heavy metals and dioxins in the air. And chloride ions will combine with water molecules to form compounds and settle to the bottom, making them adhere to each other and reduce to the bottom to fuse with cement. Finally, the well-stirred mixture will move into the sintering component, be stored quantitatively by the sintering component, and the mixture will be heated to make it solidify and can be recycled as a substrate.

[0007] The stirring component includes a support plate, a connecting block, and a cylinder. The support plate is located on the horizontal ground. There are two support plates. A connecting block is provided between the two support plates. A cylinder is provided at the top of the connecting block. The cylinder is rotatably connected to the connecting block. A rotating motor is provided at the bottom of the connecting block. The fixed end of the rotating motor is fixedly connected to the connecting block. A gear ring is provided on the outer wall of the cylinder. The output end of the rotating motor is fixedly connected to the gear ring. Stirring cutters are provided on the inner wall of the cylinder.

[0008] Specifically, the support plate is located on the horizontal ground, used to support the cylinder and provide a rotating space so that the cylinder can rotate. The upper surface of the connecting block is an arc-shaped groove, which is matched with the bottom end of the cylinder. And the heights of both ends of the connecting block are different, making the cylinder inclined to the horizontal plane, so that the materials in the cylinder can move slowly. The rotating motor, as a power source, controls the rotation of the cylinder through tooth pattern cooperation. The rotation of the cylinder will drive the stirring cutters and the materials to move, preventing the materials from always settling at the bottom end of the cylinder, resulting in the materials not being able to absorb water mist and then solidifying. The stirring cutters are used to drive the materials at the bottom end inside the cylinder to move.

[0009] The moisture retention component includes an annular pipe and a water injection pipe. The annular pipe is located on the inner wall of the cylinder and is fixedly connected to the inner wall of the cylinder. A cavity is opened in the cylinder, and the annular pipe is communicated with the cavity. The water injection pipe is located on the outer wall of the cylinder and is fixedly connected to the outer wall of the cylinder. A connecting pipe is provided at the top of the water injection pipe, and the connecting pipe is slidably connected to the water injection pipe.

[0010] Specifically, the moisture preservation component is used to maintain the water content in the internal space of the cylinder body. At the same time, it can also adsorb the fly ash at the top end inside the cylinder body, so that heavy metals, chlorine ions and dioxins settle to the bottom and mix with cement. Thus, the moisture preservation component works to achieve secondary filtration, clean the remaining fly ash, and water is injected into the cavity inside the cylinder body. The cavity, the annular pipe and the water injection pipe cooperate to form a flowing water path, and together with the water mist, it can also cool the whole cylinder body, preventing the materials inside the cylinder body from being affected when the sintering component is heated, so that the cylinder body can work continuously. Among them, the connecting pipe is connected to an external water pipe for continuously providing water source.

[0011] The annular pipe is provided with connecting seats. The connecting seats are fixedly connected to the annular pipe. A water groove is opened in the middle of the connecting seat. The water groove is communicated with the internal space of the annular pipe. Water outlet holes are opened on both sides of the connecting seat. The water outlet holes are communicated with the water groove. A sliding cover is provided at the top end of the connecting seat. The sliding cover is slidably connected to the connecting seat. A convex block is provided on the inner wall of the sliding cover. The convex block cooperates with the water groove. A first magnetic block is provided in the middle of the convex block, and a second magnetic block is provided in the water groove.

[0012] Specifically, several annular pipes are provided and are all installed on the inner wall of the cylinder body at equal intervals. Several connecting seats are also provided and are all installed on the annular pipes at equal intervals. When water flows through the annular pipes, the liquid will move into the water grooves in the connecting seats, and then move to the water outlet holes through the space of the water grooves for spraying. The sliding cover is used to seal the water outlet holes and the water grooves. When the connecting seat is at the bottom end, it will come into contact with the mixture. Due to the plasticity of the mixture, the mixture is likely to block the water outlet holes, resulting in the failure of the moisture preservation component. The sliding cover is slidably connected to the connecting seat. Thus, when the connecting seat is at the bottom end, the sliding cover will move towards the connecting seat due to its own weight and the magnetic attraction of the two magnetic blocks, so that the movement of the sliding cover drives the convex block to move, making the convex block engage with the water groove. Suppose the cylinder body rotates clockwise, the materials will gather between the left end and the bottom end inside the cylinder body. Due to the magnetic attraction, the bottom end and the left end of the cylinder body are in a sealed state, and the top end of the cylinder body is in a spraying state. When at the right end of the cylinder body, because the sliding cover and the connecting seat are parallel to the horizontal line and under the action of water pressure, it will also be in a spraying state. On the contrary, when the cylinder body rotates counterclockwise, the materials will gather between the right end and the bottom end inside the cylinder body. The bottom end and the right end of the cylinder body are in a sealed state, and the top end and the left end of the cylinder body are in a spraying state. Furthermore, when the connecting seat sprays, it will not come into large-area contact with the materials, and when the materials splash onto the connecting seat during the stirring of the materials, they will also preferentially come into contact with the sliding cover.

[0013] The discharging component includes a discharging bin, a side discharging pipe and a top discharging pipe. The discharging bin is located on one side of the cylinder body. The discharging bin is rotatably connected to the cylinder body. A through groove is opened in the discharging bin. The through groove is communicated with the internal space of the cylinder body. The side discharging pipe is located on one side of the discharging bin. The side discharging pipe is communicated with the through groove. The top discharging pipe is located at the top end of the discharging bin. The top discharging pipe is communicated with the pipe groove. A filter plate is provided in the side discharging pipe.

[0014] Specifically, the tipping bin is used to provide a mixing space for fly ash and cement, so that when the two come into contact in the pipeline, they start to mix, thereby forming a primary filtration. Among them, the side tipping pipe is used to connect with the external fly ash transportation pipe, and the top tipping pipe is used to connect with the external cement transportation pipe. The pipe groove where the top tipping pipe is connected to the through groove is inclined, so that the cement moves towards the cylinder body under the drive of gravity and the push of fly ash, preventing the cement from moving to the side tipping pipe. Then, the filter plate is used to filter out larger particulate matters in the fly ash.

[0015] The sintering assembly includes a box body, a storage tabletop and a sliding door. The box body is located on the side of the cylinder body away from the tipping bin. The box body is rotatably connected to the cylinder body. An inlet is provided on one side of the box body, and the inlet is communicated with the internal space of the cylinder body. The sliding door is located in the inlet. A chute is provided in the box body, and the top end of the sliding door is slidably connected to the chute. The sliding door cooperates with the inlet hole. An outlet is provided on one side of the box body, and the outlet is located at the position of the box body away from the inlet. A flip door is provided at the outlet, and the flip door is rotatably connected to the box body. A groove is provided on the inner wall of the box body. The storage tabletop is located in the box body. One end of the storage tabletop is slidably connected to the groove, and the other end of the storage tabletop is rotatably connected to the bottom end of the sliding door.

[0016] Specifically, the sintering assembly is used to provide a sealed heating environment to heat the mixture so that the mixture becomes a solid substrate. When the mixture stirred by the cylinder body passes through the inlet and then enters the box body and falls onto the storage tabletop. As time goes by, more and more mixture will accumulate on the storage tabletop, and the weight of the storage tabletop increases and it moves downward. The movement of the storage tabletop will drive the movement of the sliding door. As the sliding door closes, a sealed space is formed. Among them, the groove is located at the bottom end of the outlet, and the top end of the inlet is higher than the top end of the groove. Thus, when transporting the substrate, one end of the storage tabletop will first contact the groove. Restricted by the groove, the storage tabletop tilts. The end of the storage tabletop close to the outlet is low, and the end close to the inlet is high. Then, due to its own weight, the substrate moves towards the lower end, and then the substrate will squeeze the flip door to move out of the outlet.

[0017] A pushing motor is provided at the bottom end of the box body. The fixed end of the pushing motor is fixedly connected to the bottom end of the box body. The output end of the pushing motor is located in the internal space of the box body. A pushing plate is provided at the output end of the pushing motor. The pushing plate is rotatably connected to the output end of the pushing motor. A coil is provided at the bottom end inside the box body, and a magnetic column is provided at the bottom end of the pushing plate. The coil and the magnetic column are on the same central axis.

[0018] Specifically, the driving motor is used as a power source to control the up-and-down movement of the pushing plate. The output end of the driving motor is normally located at the bottom end of the feeding port, so that the pushing plate is maintained at the bottom end of the feeding port, without applying pressure to the pushing plate. During the pouring process of the mixture, the storage table will slowly move downward, driving the pushing plate to move downward. One end of the magnetic column at the bottom end of the pushing plate penetrates through the coil, and then an induced electromotive force is generated at both ends of the coil, and then a voltage value is generated. The longer the immersed end is, the stronger the induced electromotive force is, and the larger the voltage value is. When the voltage value is at a high value, that is, when the pushing plate is at the bottommost end inside the box body and the sliding door completely seals the feeding port, the driving motor will start to work after waiting for a period of time, and the waiting time is the heating time of the mixture.

[0019] A collection port is provided at the top end of the box body, and a heating element is provided on the inner wall of the box body.

[0020] Specifically, when the driving motor works, the pushing plate will push the storage table to move, and the storage table will drive the base material to move. The movement of the base material and the storage table will squeeze the internal space of the box body, causing the air inside the box body to move upward. The moving air will gather at the collection port, and the collection port is connected to the side discharge pipe. During the stirring process, part of the gas will penetrate into the box body, and the penetrated gas will be collected and processed by squeezing through the storage table to prevent the leakage of untreated gas. The heating element is used to provide high temperature inside the box body to solidify the mixture.

[0021] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, the pouring bin is used to provide a mixing space for fly ash and cement, so that when the two come into contact in the pipeline, they start to mix, enabling the cement to adsorb and wrap heavy metals, chloride ions and dioxins, thereby forming a primary filtration.

[0022] 2. When the mixture enters the cylinder body, the connecting seat moves to the top end inside the cylinder body. Under the action of water pressure, it is in a spraying state, maintaining the water content in the internal space of the cylinder body. At the same time, it can also adsorb the fly ash at the top end inside the cylinder body, causing heavy metals, chloride ions and dioxins to settle to the bottom and mix with the cement. Thus, the moisture preservation component works to achieve secondary filtration and clean the remaining fly ash. The cavity inside the cylinder body is filled with water, and the cavity, the annular pipe and the water injection pipe cooperate to form a flowing water path, which can also cool the whole cylinder body in cooperation with the water mist, preventing the heating of the sintering component from affecting the materials inside the cylinder body and enabling the cylinder body to continue to work.

[0023] 3. When the present invention is working, as time goes by, more and more mixture will accumulate on the storage table, the weight of the storage table increases and it moves downward. The movement of the storage table will drive the sliding door to move. As the sliding door closes, a sealed space is formed, so that the base materials produced by the device are all of the same size, which is convenient for subsequent collection and transportation.

[0024] 4. When the driving motor of the present invention works, it drives the storage table to move. One end of the storage table will first contact the groove. Restricted by the groove, the storage table tilts. The end of the storage table close to the discharge port is low, and the end close to the feed port is high. Thus, the substrate moves towards the lower end due to its own weight, and then the substrate will squeeze the discharge port of the flip door to move out. The infiltrated gas is collected and processed by squeezing the storage table, preventing the leakage of untreated gas. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] Embodiment: As Figures 1 to 7As shown in the figure, the present invention provides a technical solution for a hierarchical circulation filtration device for fly ash treatment. The filtration device includes a feeding component 1, a stirring component 2, a humidity maintaining component 3, and a sintering component 4. A stirring component 2 is provided on one side of the feeding component 1. The stirring component 2 is used for stirring the mixed materials. A humidity maintaining component 3 is provided inside the stirring component 2. The humidity maintaining component 3 is used for maintaining the overall humidity of the mixture. A sintering component 4 is provided on one side of the stirring component 2. The sintering component 4 is used for heating the mixture.

[0029] Specifically, the filtration device is used to treat heavy metals, chlorine ions, and dioxins in fly ash. Direct discharge will cause serious environmental pollution. Among them, the chlorine ions are gaseous, and the heavy metals and dioxins are solid. Therefore, multiple devices are used for targeted filtration of the three, resulting in excessive costs. The feeding component 1 is used to mix and transport fly ash and cement materials. Through the adhesiveness and plasticity of cement, heavy metals and dioxins in the fly ash are adsorbed and sealed. Then, the mixture of the feeding component 1 will be transported into the stirring component 2. The rotation of the stirring component 2 improves the mixing degree of the two. Then, the humidity maintaining component 3 in the stirring component 2 ensures the water content in the cement, so that it will not solidify due to the influence of the sintering component 4 or humidity. When the humidity maintaining component 3 sprays water mist, it will also adhere to heavy metals and dioxins in the air. And the chlorine ions will combine with water molecules to form compounds and settle to the bottom, making them adhere to each other and reduce to the bottom to fuse with the cement. Finally, the well-stirred mixture will move into the sintering component 4, be stored quantitatively by the sintering component 4, and the mixture will be heated to make it solidify and can be recycled as a base material.

[0030] As Figure 1 , Figure 2 , Figure 5 As shown in the figure, the stirring component 2 includes a support plate 21, a connecting block 22, and a cylinder 23. The support plate 21 is located on the horizontal ground. There are two support plates 21. A connecting block 22 is provided between the two support plates 21. A cylinder 23 is provided at the top of the connecting block 22. The cylinder 23 is rotatably connected to the connecting block 22. A rotating motor 24 is provided at the bottom end of the connecting block 22. The fixed end of the rotating motor 24 is fixedly connected to the connecting block 22. A gear ring 25 is provided on the outer wall of the cylinder 23. The output end of the rotating motor 24 is fixedly connected to the gear ring 25. Stirring cutters 26 are provided on the inner wall of the cylinder 23.

[0031] Specifically, the support plate 21 is located on the horizontal ground and is used to support the cylinder body 23 and provide a rotating space, enabling the cylinder body 23 to rotate on its own. The upper surface of the connecting block 22 is an arc-shaped groove 414, which is matched with the bottom end of the cylinder body 23. Moreover, the heights of both ends of the connecting block 22 are different, causing the cylinder body 23 to be inclined to the horizontal plane, so that the materials inside the cylinder body 23 can move slowly. The rotating motor 24, as a power source, controls the rotation of the cylinder body 23 through tooth pattern matching. The rotation of the cylinder body 23 will drive the stirring tool 26 and the materials to move, preventing the materials from always settling at the bottom end of the cylinder body 23, resulting in the materials not being able to absorb water mist and then solidifying. The stirring tool 26 is used to drive the materials at the bottom end inside the cylinder body 23.

[0032] As Figure 1 , Figure 2 , Figure 5 As shown, the moisture preservation component 3 includes an annular pipe 31 and a water injection pipe 32. The annular pipe 31 is located on the inner wall of the cylinder body 23 and is fixedly connected to the inner wall of the cylinder body 23. A cavity 231 is provided inside the cylinder body 23, and the annular pipe 31 is communicated with the cavity 231. The water injection pipe 32 is located on the outer wall of the cylinder body 23 and is fixedly connected to the outer wall of the cylinder body 23. A connecting pipe 33 is provided at the top of the water injection pipe 32, and the connecting pipe 33 is slidably connected to the water injection pipe 32.

[0033] Specifically, the moisture preservation component 3 is used to maintain the water content in the internal space of the cylinder body 23. At the same time, it can also adsorb the fly ash at the top end inside the cylinder body 23, causing heavy metals, chloride ions, and dioxins to settle to the bottom and mix with cement. Thus, when the moisture preservation component 3 works, it realizes secondary filtration and cleans the residual fly ash. Moreover, the cavity 231 inside the cylinder body 23 is filled with water, and the cavity 231, the annular pipe 31, and the water injection pipe 32 cooperate to form a flowing water path, which can also cool the entire cylinder body 23 in cooperation with the water mist, preventing the materials inside the cylinder body 23 from being affected when the sintering component 4 is heated, enabling the cylinder body 23 to continue working. Among them, the connecting pipe 33 is connected to an external water pipe for continuously providing water source.

[0034] As Figures 5 to 7 shown, a connecting seat 34 is provided on the annular pipe 31. The connecting seat 34 is fixedly connected to the annular pipe 31. A water tank 341 is provided in the middle of the connecting seat 34, and the water tank 341 is communicated with the internal space of the annular pipe 31. Water outlet holes 342 are provided on both sides of the connecting seat 34, and the water outlet holes 342 are communicated with the water tank 341. A sliding cover 35 is provided at the top of the connecting seat 34, and the sliding cover 35 is slidably connected to the connecting seat 34. A convex block 36 is provided on the inner wall of the sliding cover 35, and the convex block 36 is matched with the water tank 341. A first magnetic block 37 is provided in the middle of the convex block 36, and a second magnetic block 38 is provided in the water tank 341.

[0035] Specifically, a number of annular pipes 31 are provided and are all installed equidistantly on the inner wall of the cylinder body 23. A number of connecting seats 34 are also provided and are all installed equidistantly on the annular pipe 31. When water flows through the annular pipe 31, the liquid will move into the water tank 341 in the connecting seat 34, and then move to the water outlet hole 342 through the space of the water tank 341 for spraying. Among them, the sliding cover 35 is used to seal the water outlet hole 342 and the water tank 341. When the connecting seat 34 is at the bottom end, it will come into contact with the mixture. Due to the plasticity of the mixture, the mixture is likely to block the water outlet hole 342, resulting in the failure of the moisture preservation component 3. The sliding cover 35 is slidably connected to the connecting seat 34. Thus, when the connecting seat 34 is at the bottom end, the sliding cover 35 will move towards the connecting seat 34 due to its own weight and the magnetic attraction of the two magnets, so that the sliding cover 35 drives the convex block 36 to move, making the convex block 36 engage with the water tank 341. Suppose the cylinder body 23 rotates clockwise, the material will accumulate between the left end and the bottom end inside the cylinder body 23. Due to the magnetic attraction, the bottom end and the left end of the cylinder body 23 are in a sealed state, and the top end of the cylinder body 23 is in a spraying state. When at the right end of the cylinder body 23, because the sliding cover 35 and the connecting seat 34 are parallel to the horizontal line and under the action of water pressure, it will also be in a spraying state. On the contrary, when the cylinder body 23 rotates counterclockwise, the material will accumulate between the right end and the bottom end inside the cylinder body 23. The bottom end and the right end of the cylinder body 23 are in a sealed state, and the top end and the left end of the cylinder body 23 are in a spraying state. Furthermore, when the connecting seat 34 sprays, it will not come into large-area contact with the material. And when stirring the material, when the material splashes onto the connecting seat 34, it will preferentially come into contact with the sliding cover 35.

[0036] As Figure 1 、 Figure 2 shown, the pouring component 1 includes a pouring bin 11, a side pouring pipe 12 and a top pouring pipe 13. The pouring bin 11 is located on one side of the cylinder body 23. The pouring bin 11 is rotatably connected to the cylinder body 23. A through groove is formed in the pouring bin 11, and the through groove is communicated with the internal space of the cylinder body 23. The side pouring pipe 12 is located on one side of the pouring bin 11. The side pouring pipe 12 is communicated with the through groove. The top pouring pipe 13 is located at the top of the pouring bin 11. The top pouring pipe 13 is communicated with the pipe groove. A filter plate 14 is provided in the side pouring pipe 12.

[0037] Specifically, the pouring bin 11 is used to provide a mixing space for fly ash and cement, so that when the two come into contact in the pipeline, they start to mix, thereby forming a primary filtration. Among them, the side pouring pipe 12 is used to connect with an external fly ash transportation pipe, and the top pouring pipe 13 is used to connect with an external cement transportation pipe. The pipe groove where the top pouring pipe 13 is connected to the through groove is inclined, so that the cement moves towards the cylinder body 23 under the drive of gravity and the push of fly ash, preventing the cement from moving to the side pouring pipe 12. Then, the filter plate 14 is used to filter out larger particulate matters in the fly ash.

[0038] As Figures 1 to 3As shown, the sintering assembly 4 includes a box body 41, a storage tabletop 42 and a sliding door 43. The box body 41 is located on the side of the cylinder body 23 away from the discharging bin 11. The box body 41 is rotatably connected to the cylinder body 23. An inlet 411 is provided on one side of the box body 41. The inlet 411 is communicated with the inner space of the cylinder body 23. The sliding door 43 is located in the inlet 411. A chute 413 is provided in the box body 41. The top end of the sliding door 43 is slidably connected to the chute 413. The sliding door 43 is matched with the inlet hole. An outlet 412 is provided on one side of the box body 41. The outlet 412 is located at the position of the box body 41 away from the inlet 411. A flip door 44 is provided at the outlet 412. The flip door 44 is rotatably connected to the box body 41. A groove 414 is provided on the inner wall of the box body 41. The storage tabletop 42 is located in the box body 41. One end of the storage tabletop 42 is slidably connected to the groove 414. The other end of the storage tabletop 42 is rotatably connected to the bottom end of the sliding door 43.

[0039] Specifically, the sintering assembly 4 is used to provide a sealed heating environment to heat the mixture so that the mixture becomes a solid substrate. When the mixture stirred by the cylinder body 23 enters the box body 41 through the inlet 411 and falls onto the storage tabletop 42. As time goes by, the mixture on the storage tabletop 42 will accumulate more and more, the weight of the storage tabletop 42 increases, and it moves downward. The movement of the storage tabletop 42 will drive the movement of the sliding door 43. As the sliding door 43 closes, a sealed space is formed. The groove 414 is located at the bottom end of the outlet 412, and the top end of the inlet 411 is higher than the top end of the groove 414. Thus, when transporting the substrate, one end of the storage tabletop 42 will first contact the groove 414. Restricted by the groove 414, the storage tabletop 42 tilts. The end of the storage tabletop 42 close to the outlet 412 is low, and the end close to the inlet 411 is high. Then the substrate moves toward the lower end due to its own weight, and then the substrate will squeeze the flip door 44 and move out of the outlet 412.

[0040] As Figures 1 to 4 As shown, a pushing motor 45 is provided at the bottom end of the box body 41. The fixed end of the pushing motor 45 is fixedly connected to the bottom end of the box body 41. The output end of the pushing motor 45 is located in the inner space of the box body 41. A pushing plate 46 is provided at the output end of the pushing motor 45. The pushing plate 46 is rotatably connected to the output end of the pushing motor 45. A coil 47 is provided at the bottom end inside the box body 41. A magnetic column 48 is provided at the bottom end of the pushing plate 46. The coil 47 and the magnetic column 48 are on the same central axis.

[0041] Specifically, the driving motor 45 serves as a power source to control the up-and-down movement of the pushing plate 46. The output end of the driving motor 45 is normally located at the bottom end of the feeding port 411, so that the pushing plate 46 is maintained at the bottom end of the feeding port 411, without applying pressure to the pushing plate 46. During the pouring of the mixture, the storage table 42 will slowly move downward, driving the pushing plate 46 to move downward. One end of the magnetic column 48 at the bottom end of the pushing plate 46 penetrates through the coil 47, and an induced electromotive force is generated at both ends of the coil 47, thereby generating a voltage value. The longer the immersed end is, the stronger the induced electromotive force is, and the larger the voltage value is. When the voltage value is at a high level, that is, when the pushing plate 46 is at the bottommost end inside the box body 41 and the sliding door 43 completely seals the feeding port 411, the driving motor 45 will start working after waiting for a period of time, and the waiting time is the heating time of the mixture.

[0042] As Figure 2 , Figure 3 shown, a collection port 415 is opened at the top end of the box body 41, and a heating element 49 is provided on the inner wall of the box body 41.

[0043] Specifically, when the driving motor 45 works, the pushing plate 46 will push the storage table 42 to move, and the storage table will drive the base material to move. The movement of the base material and the storage table will squeeze the internal space of the box body 41, causing the air inside the box body 41 to move upward. The moving air will gather at the collection port 415, and the collection port 415 is connected to the side pouring pipe 12. During the stirring process, some gases will penetrate into the box body 41, and the penetrated gases are collected and processed by the extrusion of the storage table to prevent the leakage of untreated gases. The heating element 49 is used to provide high temperature inside the box body 41 to solidify the mixture.

[0044] Working principle: Its fly ash enters the trough through the side discharge pipe 12, and cement enters the trough through the top discharge pipe 13. Driven by gravity and pushed by the fly ash, the cement moves towards the cylinder body 23. Then, the rotation motor 24 serves as the power source and controls the rotation of the cylinder body 23 through tooth pattern cooperation. The rotation of the cylinder body 23 drives the stirring cutter 26 and the material to move, preventing the material from continuously settling at the bottom of the cylinder body 23. During this period, when the connecting seat 34 moves to the inner top end of the cylinder body 23, it is in a spraying state under the action of water pressure. On the contrary, when the cylinder body 23 is at the lower end, the cover will move the sliding cover 35 towards the connecting seat 34 due to its own weight and the magnetic attraction of the two magnets, sealing the water tank 341 and the water outlet hole 342 to prevent cement from infiltrating. When the mixture stirred by the cylinder body 23 enters the box body 41 through the feeding port 411 and falls onto the storage table 42. As time goes by, the mixture on the storage table 42 will accumulate more and more, and the weight of the storage table 42 increases and it moves downward. The movement of the storage table 42 drives the movement of the sliding door 43. As the sliding door 43 closes, a sealed space is formed, and then one end of the magnetic column 48 at the bottom of the pushing plate 46 penetrates through the coil 47, and then an induced electromotive force is generated at both ends of the coil 47, and then a voltage value is generated. When the voltage value is at a high value, the heating element 49 will start heating, and the pushing motor 45 will start working after waiting for a period of time, pushing the storage table 42 to move. One end of the storage table 42 will first contact the groove 414. Restricted by the groove 414, the storage table 42 tilts. The end of the storage table 42 close to the discharge port 412 is low, and the end close to the feeding port 411 is high. Then, the substrate moves towards the lower end due to its own weight, and the substrate will squeeze the flip door 44 to move outside the discharge port 412, and the infiltrated gas is collected and processed by squeezing through the storage table, preventing the leakage of untreated gas.
