Description

Technical Field

[0001] The invention relates to the technical field of filter devices, in particular to a graded circulation filter device for fly ash treatment. Background Art

[0002] Waste incineration fly ash refers to the by-product that adheres to the outer wall of the waste heat boiler in the form of fly ash during the waste incineration process, or enters the flue gas purification system and is captured by the dust collector. It is generally composed of chlorides, sulfates, aluminosilicates, silicate minerals, heavy metals and dioxins. Among them, heavy metals, dioxins and chlorides are the main problems that currently plague the harmlessness and resource utilization of fly ash.

[0003] The filtration device is 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 cement solidification technology, which uses the fly ash from garbage incineration as a solidifying raw material and solidifies it with cement and other substances to form a usable building material. However, due to the fluidity of the fly ash itself during the filtration process, cement and other substances cannot completely cover the fly ash, resulting in some fly ash being unable to be processed. The fusion of fly ash and cement and other substances requires heating, and the high temperature generated by heating will affect the untreated cement and other substances, causing them to solidify, reducing the overall filtration effect. Staff are also required to process it, thereby increasing work costs. Summary of the Invention

[0004] The object 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-mentioned purpose, the present invention provides the following technical solutions: a graded circulation filtration device for fly ash treatment, the filtration device including a pouring component, a stirring component, a moisturizing component and a sintering component. A stirring component is provided on one side of the pouring component, and the stirring component is used to stir the mixed material. A moisturizing component is provided in the stirring component, and the moisturizing component is used to maintain the overall humidity of the mixture. A sintering component is provided on one side of the stirring component, and the sintering component is used to heat 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, which is too costly. The pouring component is used to mix and transport fly ash and cement materials. The cement absorbs heavy metals and dioxins in the fly ash through its adhesion and plasticity, and seals it. The mixture of the pouring component is then transported to the stirring component. The rotation of the stirring component increases the mixing degree of the two. The moisturizing 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 moisturizing component sprays water mist, it will also adhere to heavy metals and dioxins in the air, and the chloride ions will combine with water molecules to form compounds and settle to the bottom, causing them to adhere to each other and descend to the bottom to merge with the cement. Finally, the mixed mixture will be moved to the sintering component, quantitatively stored by the sintering component, and the mixture will be heated to solidify and can be recycled as a base material.

[0007] The stirring assembly 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 on 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. A stirring tool is provided on the inner wall of the cylinder.

[0008] Specifically, the support plate is located on the horizontal ground, which is used to support the cylinder and provide a rotation space so that the cylinder can rotate. The upper surface of the connecting block is an arc-shaped groove, which cooperates with the bottom end of the cylinder, and the heights of the two ends of the connecting block are different, so that the cylinder is tilted to the horizontal plane, so that the material in the cylinder can move slowly. The rotating motor is used as a power source to control the rotation of the cylinder through the tooth pattern. The rotation of the cylinder will drive the stirring tool and the material to move, preventing the material from settling at the bottom end of the cylinder, resulting in the material not absorbing water mist and then solidifying. The stirring tool is used to drive the material at the bottom end of the cylinder to move.

[0009] The moisturizing component includes an annular tube and a water injection pipe. The annular tube 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 tube is connected to 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 moisturizing component is used to maintain the water content of the internal space of the cylinder. At the same time, it can also absorb the fly ash at the top of the cylinder, so that heavy metals, chloride ions and dioxins are settled to the bottom and mixed with cement. The moisturizing component works to achieve secondary filtration and clean the remaining fly ash. The cavity in the cylinder is filled with water, and the cavity, annular pipe and water injection pipe cooperate to form a flowing water path. In conjunction with water mist, it can also cool the entire cylinder to prevent the sintering component from affecting the material in the cylinder when heated, so that the cylinder can continue to work. The connecting pipe is connected to the external water pipe for continuous water supply.

[0011] A connecting seat is provided on the annular tube, which is fixedly connected to the annular tube. A water tank is provided in the middle of the connecting seat, which is connected to the internal space of the annular tube. Water outlet holes are provided on both sides of the connecting seat, which are connected to the water tank. A sliding cover is provided on the top of the connecting seat, which is slidably connected to the connecting seat. A protrusion is provided on the inner wall of the sliding cover, which cooperates with the water tank. A first magnetic block is provided in the middle of the protrusion, and a second magnetic block is provided in the water tank.

[0012] Specifically, there are several annular tubes, which are equidistantly arranged and installed on the inner wall of the cylinder. There are also several connecting seats, which are equidistantly arranged and installed on the annular tube. When water flows through the annular tube, the liquid will move into the water tank in the connecting seat, and then move to the water outlet through the water tank space for spraying. The sliding cover is used to seal the water outlet and the water tank. When the connecting seat is at the bottom, it will come into contact with the mixture. Due to the plasticity of the mixture, the mixture can easily clog the water outlet, causing the moisturizing component to fail. The sliding cover is slidably connected to the connecting seat, so that when the connecting seat is at the bottom, the sliding cover will move toward 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 movement of the protrusion. The protrusion is engaged with the water trough. Assuming that when the cylinder rotates clockwise, the material will gather between the left end and the bottom end of the cylinder. Due to the magnetic effect, the bottom and left ends of the cylinder are in a closed state at the connecting seat, and the top of the cylinder is in a spraying state. At the right end of the cylinder, 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. Conversely, when the cylinder rotates counterclockwise, the material will gather between the right end and the bottom end of the cylinder. The bottom and right end of the cylinder are in a closed state, and the top and left end of the cylinder are in a spraying state. Therefore, the connecting seat will not contact the material over a large area when spraying, and when the material is stirred, when the material splashes to the connecting seat, it will also contact the sliding cover first.

[0013] The pouring assembly includes a pouring bin, a side pouring pipe and a top pouring pipe. The pouring bin is located on one side of the cylinder, and the pouring bin is rotatably connected to the cylinder. A through groove is provided in the pouring bin, and the through groove is connected to the internal space of the cylinder. The side pouring pipe is located on one side of the pouring bin, and the side pouring pipe is connected to the through groove. The top pouring pipe is located at the top of the pouring bin, and the top pouring pipe is connected to the pipe groove. A filter plate is provided in the side pouring pipe.

[0014] Specifically, the dumping bin is used to provide a mixing space for fly ash and cement, so that the two begin to mix when they come into contact in the pipeline, thereby forming a primary filtration, wherein the side dumping pipe is used to connect with the external fly ash transport pipe, and the top dumping pipe is used to connect with the external cement transport pipe. The pipe groove connecting the top dumping pipe and the through groove is inclined, so that the cement moves toward the cylinder under the drive of gravity and the push of fly ash, preventing the cement from moving to the side dumping pipe, and then, the filter plate is used to filter out larger particles in the fly ash.

[0015] The sintering assembly includes a box body, a storage table and a sliding door. The box body is located on the side of the cylinder away from the pouring bin, and the box body is rotatably connected to the cylinder. A feed port is provided on one side of the box body, and the feed port is communicated with the internal space of the cylinder. The sliding door is located in the feed port, and a slide groove is provided in the box body. The top of the sliding door is slidably connected to the slide groove, and the sliding door cooperates with the feed hole. A discharge port is provided on one side of the box body, and the discharge port is located at the box body away from the feed port. A flip door is provided at the discharge port, and the flip door is rotatably connected to the box body. A groove is provided on the inner wall of the box body, and the storage table is located in the box body, and one end of the storage table is slidably connected to the groove, and the other end of the storage table is rotatably connected to the bottom end of the sliding door.

[0016] Specifically, the sintering assembly is used to provide a closed heating environment to heat the mixture so that the mixture becomes a solid matrix. When the mixture is stirred in the cylinder, it will pass through the inlet and into the box, and fall onto the storage table. As time goes by, the mixture on the storage table will accumulate more and more, the weight of the storage table will increase, and it will move downward. The movement of the storage table will drive the sliding door to move. As the sliding door closes, a closed space is formed, in which the groove is located at the bottom of the discharge port, and the top of the feed port is higher than the top of the groove. Therefore, when transporting the substrate, one end of the storage table will first contact the groove. Restricted by the groove, the storage table will tilt, and the storage table will be lower at the end close to the discharge port and higher at the end close to the feed port. Then, the substrate will move to the lower end due to its own weight, and then the substrate will squeeze the flip door to move out of the discharge port.

[0017] A pushing motor is provided at the bottom of the box, and the fixed end of the pushing motor is fixedly connected to the bottom of the box. The output end of the pushing motor is located in the internal space of the box. A pushing plate is provided at the output end of the pushing motor, and the pushing plate is rotatably connected to the output end of the pushing motor. A coil is provided at the bottom end of the box, 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 push motor is used as a power source to control the up and down movement of the push plate. The output end of the push motor is normally at the bottom of the feed port, so that the push plate is maintained at the bottom of the feed port, and no pressure is applied to the push plate. During the pouring of the mixture, the storage table will slowly move downward, driving the push plate to move downward, and then push one end of the magnetic column at the bottom of the plate to pass through the coil, and then both ends of the coil generate an induced electromotive force, and then generate a voltage value. The longer the immersed end is, the stronger the induced electromotive force is, and the greater the voltage value is. When the voltage value is high, that is, the push plate is at the bottom of the box, the sliding door completely seals the feed port, and the push motor will start working after waiting for a period of time. The waiting time is the heating time of the mixture.

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

[0020] Specifically, when the push motor is working, the push plate will push the storage table to move, and the storage table will drive the substrate to move. The movement of the substrate and the storage table will squeeze the internal space of the box, causing the air inside the box to move to the top. The moved air will gather at the collection port, and the collection port is connected to the side dumping pipe. During the stirring process, some gas will penetrate into the box, and the infiltrated gas will be collected and processed through the squeezing of the storage table to prevent leakage of untreated gas. The heating element is used to provide high temperature to the inside of the box to solidify the mixture.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The dump silo in the present invention is used to provide a mixing space for fly ash and cement. When the two come into contact in the pipeline, they begin to mix, allowing the cement to adsorb and encapsulate heavy metals, chloride ions and dioxins, thereby forming a primary filtration.

[0023] 2. In the present invention, when the mixture enters the cylinder, the connecting seat moves to the top of the cylinder. Because it is in a spraying state under the action of water pressure, the water content of the internal space of the cylinder is maintained. At the same time, it can also absorb the fly ash at the top of the cylinder, so that heavy metals, chloride ions and dioxins are all settled to the bottom and mixed with cement, so that the moisturizing component works to achieve secondary filtration and clean the remaining fly ash. The cavity in the cylinder is filled with water, and the cavity, annular pipe and water injection pipe cooperate to form a flowing water path. In combination with water mist, the cylinder as a whole can be cooled to prevent the sintering component from affecting the material in the cylinder when heated, so that the cylinder can continue to work.

[0024] 3. When the present invention is working, as time goes by, the mixture on the storage table will accumulate more and more, the weight of the storage table will increase, and it will move downward. The movement of the storage table will drive the sliding door to move. As the sliding door closes, a closed space is formed, so that the substrates produced by the device are all of the same size, which is convenient for subsequent collection and transportation.

[0025] 4. When the motor of the present invention is working, it pushes the storage table to move. One end of the storage table will first contact the groove. Restricted by the groove, the storage table will tilt. The end of the storage table close to the discharge port is low, and the end close to the feed port is high. Then, the substrate moves to the lower end due to its own weight, and then the substrate will squeeze the flip door to move out of the discharge port. The infiltrated gas is collected and processed through the squeezing of the storage table to prevent the leakage of untreated gas. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0035] Example: Figures 1 to 7 As shown, the present invention provides a technical solution for a graded circulation filtration device for fly ash treatment, the filtration device includes a pouring component 1, a stirring component 2, a moisturizing component 3 and a sintering component 4. A stirring component 2 is provided on one side of the pouring component 1, and the stirring component 2 is used to stir the mixed material. A moisturizing component 3 is provided in the stirring component 2, and the moisturizing component 3 is used to maintain the overall humidity of the mixture. A sintering component 4 is provided on one side of the stirring component 2, and the sintering component 4 is used to heat the mixture.

[0036] Specifically, the filtering device is used to treat heavy metals, chloride ions and dioxins in fly ash. Direct discharge will cause serious environmental pollution. Chloride ions are gaseous, heavy metals and dioxins are solid, so the three filters are targeted by using multiple devices, which is too costly. The pouring component 1 is used to mix and transport fly ash and cement materials. The cement is adhered to and plasticized to absorb heavy metals and dioxins in the fly ash and seal it. Then the mixture of the pouring component 1 will be transported to the stirring component 2. Rotation improves the mixing degree of the two, and then the moisturizing component 3 in the stirring component 2 ensures the water content in the cement, so that it will not be solidified by the sintering component 4 or humidity. When the moisturizing component 3 sprays water mist, it will also adhere to the heavy metals and dioxins in the air, and the chloride ions will combine with water molecules to form compounds and settle to the bottom, causing them to adhere to each other and descend to the bottom to merge with the cement. Finally, the stirred mixture will be moved to the sintering component 4, and quantitatively stored by the sintering component 4. The mixture is heated to solidify and can be recycled as a base material.

[0037] like Figure 1 、 Figure 2 、 Figure 5 As shown, the stirring assembly 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 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. A stirring tool 26 is provided on the inner wall of the cylinder 23.

[0038] Specifically, the support plate 21 is located on the horizontal ground, used to support the cylinder 23 and provide a rotation space so that the cylinder 23 can rotate. The upper surface of the connecting block 22 is an arc-shaped groove 414, which cooperates with the bottom end of the cylinder 23, and the heights of the two ends of the connecting block 22 are different, so that the cylinder 23 is inclined to the horizontal plane, so that the material in the cylinder 23 can move slowly. The rotating motor 24 serves as a power source and controls the rotation of the cylinder 23 through the tooth pattern. The rotation of the cylinder 23 will drive the stirring tool 26 and the material to move, preventing the material from settling at the bottom end of the cylinder 23, resulting in the material not absorbing water mist and then solidifying. The stirring tool 26 is used to drive the material at the bottom end of the cylinder 23 to move.

[0039] like Figure 1 、 Figure 2 、 Figure 5 As shown, the moisturizing component 3 includes an annular tube 31 and a water injection pipe 32. The annular tube 31 is located on the inner wall of the cylinder 23 and is fixedly connected to the inner wall of the cylinder 23. A cavity 231 is provided in the cylinder 23 and the annular tube 31 is communicated with the cavity 231. The water injection pipe 32 is located on the outer wall of the cylinder 23 and is fixedly connected to the outer wall of the cylinder 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.

[0040] Specifically, the moisturizing component 3 is used to maintain the water content of the internal space of the cylinder 23. At the same time, it can also absorb the fly ash at the top of the cylinder 23, so that the heavy metals, chloride ions and dioxins are all settled to the bottom and mixed with cement. The moisturizing component 3 works to achieve secondary filtration and clean the remaining fly ash. The cavity 231 in the cylinder 23 is injected with water. The cavity 231, the annular tube 31 and the water injection pipe 32 cooperate to form a flowing water path. In conjunction with the water mist, the cylinder 23 can also be cooled as a whole to prevent the sintering component 4 from affecting the material in the cylinder 23 when heated, so that the cylinder 23 can continue to work. The connecting pipe 33 is connected to the external water pipe for continuously providing water.

[0041] like Figures 5 to 7 As shown, a connecting seat 34 is provided on the annular tube 31, and the connecting seat 34 is fixedly connected to the annular tube 31. A water trough 341 is provided in the middle of the connecting seat 34, and the water trough 341 is connected to the internal space of the annular tube 31. Water outlet holes 342 are provided on both sides of the connecting seat 34, and the water outlet holes 342 are connected to the water trough 341. A sliding cover 35 is provided on the top of the connecting seat 34, and the sliding cover 35 is slidably connected to the connecting seat 34. A protrusion 36 is provided on the inner wall of the sliding cover 35, and the protrusion 36 cooperates with the water trough 341. A first magnetic block 37 is provided in the middle of the protrusion 36, and a second magnetic block 38 is provided in the water trough 341.

[0042] Specifically, there are several annular tubes 31, and they are all equidistantly arranged and installed on the inner wall of the cylinder 23. There are also several connecting seats 34, and they are all equidistantly arranged and installed on the annular tube 31. When water flows through the annular tube 31, the liquid will move into the water tank 341 in the connecting seat 34, and then move to the water outlet 342 through the space of the water tank 341 for spraying. The sliding cover 35 is used to seal the water outlet 342 and the water tank 341. When the connecting seat 34 is at the bottom, it will come into contact with the mixture. Due to the plasticity of the mixture, the mixture can easily block the water outlet 342, causing the moisturizing component 3 to fail. The sliding cover 35 is slidably connected to the connecting seat 34, so that when the connecting seat 34 is at the bottom, the sliding cover 35 will move toward the connecting seat 34 due to its own weight and the magnetic attraction of the two magnetic blocks, so that the sliding cover 35 moves with The movable protrusion 36 moves, so that the protrusion 36 engages with the water trough 341. Assuming that when the cylinder 23 rotates clockwise, the material will gather between the left end and the bottom end of the cylinder 23. Due to the magnetic attraction, the bottom and left ends of the cylinder 23 are in a closed state at the connecting seat 34, and the top of the cylinder 23 is in a spraying state. At the right end of the cylinder 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. Conversely, when the cylinder 23 rotates counterclockwise, the material will gather between the right end and the bottom end of the cylinder 23. The bottom and right ends of the cylinder 23 are in a closed state, and the top and left ends of the cylinder 23 are in a spraying state. As a result, the connecting seat 34 will not contact the material over a large area when spraying, and when the material is stirred, when the material splashes to the connecting seat 34, it will also contact the sliding cover 35 first.

[0043] like Figure 1 、 Figure 2 As shown, the pouring assembly 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 23, and the pouring bin 11 is rotatably connected to the cylinder 23. A through groove is provided in the pouring bin 11, and the through groove is connected to the internal space of the cylinder 23. The side pouring pipe 12 is located on one side of the pouring bin 11, and the side pouring pipe 12 is connected to the through groove. The top pouring pipe 13 is located at the top of the pouring bin 11, and the top pouring pipe 13 is connected to the pipe groove. A filter plate 14 is provided in the side pouring pipe 12.

[0044] Specifically, the dumping bin 11 is used to provide a mixing space for fly ash and cement, so that the two begin to mix when they come into contact in the pipeline, thereby forming a filtration. The side dumping pipe 12 is used to connect with the external fly ash transport pipe, and the top dumping pipe 13 is used to connect with the external cement transport pipe. The pipe groove connecting the top dumping pipe 13 and the through groove is inclined, so that the cement moves toward the cylinder 23 under the drive of gravity and the push of fly ash, preventing the cement from moving to the side dumping pipe 12. Then, the filter plate 14 is used to filter out larger particles in the fly ash.

[0045] like Figures 1 to 3As shown, the sintering assembly 4 includes a box body 41, a storage table 42 and a sliding door 43. The box body 41 is located on the side of the cylinder 23 away from the dump bin 11. The box body 41 is rotatably connected to the cylinder 23. A feed port 411 is provided on one side of the box body 41. The feed port 411 is connected to the internal space of the cylinder 23. The sliding door 43 is located in the feed port 411. A slide groove 413 is provided in the box body 41. The top of the sliding door 43 is slidably connected to the slide groove 413. The sliding door 43 cooperates with the feed hole, and a discharge port 412 is provided on one side of the box body 41. The discharge port 412 is located in the box body 41 away from the feed port 411. A flip door 44 is provided at the discharge port 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 table 42 is located in the box body 41. One end of the storage table 42 is slidably connected to the groove 414, and the other end of the storage table 42 is rotatably connected to the bottom end of the sliding door 43.

[0046] Specifically, the sintering assembly 4 is used to provide a closed heating environment to heat the mixture so that the mixture becomes a solid substrate. When the mixture is stirred by the cylinder 23, it will enter the box body 41 through the inlet 411 and fall onto the storage table 42. As time goes by, the mixture on the storage table 42 will accumulate more and more, the weight of the storage table 42 will increase, and it will move downward. The movement of the storage table 42 will drive the sliding door 43 to move. As the sliding door 43 closes, a closed space is formed, in which the groove 414 is located at the bottom end of the discharge port 412, and the top of the feed port 411 is higher than the top of the groove 414. Therefore, when transporting the substrate, one end of the storage table 42 will first contact the groove 414. Restricted by the groove 414, the storage table 42 tilts, and the storage table 42 is lower at the end close to the discharge port 412 and higher at the end close to the feed port 411. As a result, the substrate moves to the lower end due to its own weight, and then the substrate squeezes the flip door 44 to move out of the discharge port 412.

[0047] like Figures 1 to 4 As shown, a pushing motor 45 is provided at the bottom of the box body 41, and the fixed end of the pushing motor 45 is fixedly connected to the bottom of the box body 41. The output end of the pushing motor 45 is located in the internal space of the box body 41, and 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 of the box body 41, and 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.

[0048] Specifically, the pushing motor 45 is used as a power source to control the up and down movement of the pushing plate 46. The output end of the pushing motor 45 is normally at the bottom of the feeding port 411, so that the pushing plate 46 is maintained at the bottom of the feeding port 411, and no pressure is applied 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, and then one end of the magnetic column 48 at the bottom of the pushing plate 46 passes 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. The longer the immersed end is, the stronger the induced electromotive force is, and the greater the voltage value is. When the voltage value is at a high value, that is, the pushing plate 46 is at the bottom of the box body 41, the sliding door 43 completely seals the feeding port 411, and the pushing motor 45 will start working after waiting for a period of time. The waiting time is the heating time of the mixture.

[0049] like Figure 2 、 Figure 3 As shown, a collecting port 415 is provided at the top of the box body 41 , and a heating element 49 is provided on the inner wall of the box body 41 .

[0050] Specifically, when the push motor 45 is working, the push plate 46 will push the storage table 42 to move, and the storage table will drive the substrate to move. The movement of the substrate and the storage table will squeeze the internal space of the box 41, causing the air inside the box 41 to move toward the top, and the moved 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 gas will penetrate into the box 41, and the infiltrated gas will be collected and processed through the squeezing of the storage table to prevent the leakage of untreated gas. The heating element 49 is used to provide high temperature to the inside of the box 41 to solidify the mixture.

[0051] Working principle: the fly ash passes through the side discharge pipe 12 and then into the through trough, and the cement passes through the top discharge pipe 13 and then into the through trough. The cement moves toward the cylinder 23 under the drive of gravity and the push of the fly ash. Then, the rotating motor 24 acts as a power source to control the rotation of the cylinder 23 through the tooth pattern. The rotation of the cylinder 23 will drive the mixing tool 26 and the material to move, preventing the material from settling at the bottom of the cylinder 23 all the time. During this period, when the connecting seat 34 moves to the top of the cylinder 23, it is in a spraying state under the action of water pressure. On the contrary, when the cylinder 23 is at the lower end, the cover will move the sliding cover 35 toward the connecting seat 34 due to its own weight and the magnetic attraction of the two magnetic blocks, so that the water trough 341 and the water outlet 342 are sealed to prevent cement from seeping in. When the mixture is stirred by the cylinder 23, it will pass through the inlet 411 and then into the box body 41, and fall onto the storage table 42. As time goes by, the mixture on the storage table 42 will accumulate. As it gets more and more tired, the weight of the storage table 42 increases and moves downward. The movement of the storage table 42 will drive the sliding door 43 to move. As the sliding door 43 closes, a closed space is formed, which pushes one end of the magnetic column 48 at the bottom of the plate 46 to pass 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 high, the heating element 49 will start to heat up, and the driving motor 45 will start to work 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, and the end of the storage table 42 close to the discharge port 412 is low, and the end close to the feed port 411 is high. Then, the substrate moves to the lower end due to its own weight, and then the substrate will squeeze the flip door 44 to move out of the discharge port 412. The infiltrated gas is collected and processed through the squeezing of the storage table to prevent the leakage of untreated gas.
