Description

Technical Field

[0001] The invention relates to the technical field of fly ash treatment, in particular to a fly ash filtering device with a cleaning function for fly ash treatment. Background Art

[0002] Fly ash is a tiny ash particle discharged during the combustion of fuel and is classified as hazardous waste. During the incineration process, a large amount of fly ash is produced, which may contain heavy metals and other harmful substances. If fly ash is not controlled or treated, it will cause air pollution, enter water bodies and clog rivers, and some chemicals in it will cause harm to organisms and humans. Therefore, it is very important to properly handle fly ash.

[0003] In the prior art, the general method for fly ash treatment is to directly collect the fly ash through a collection device. However, this method has some problems. First, the fly ash after collection is still in a flying state in the collection device, which increases the health risk of the staff when handling the fly ash later. Secondly, the chloride content in the fly ash is high. If it is not pre-treated, it may affect its subsequent resource utilization and increase the risk of heavy metal leaching. Summary of the invention

[0004] The object of the present invention is to provide a fly ash filtering device with a cleaning function for fly ash treatment to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: The fly ash filtering device includes a collecting mechanism, a water injection mechanism, a separation mechanism and a cleaning mechanism. The collecting mechanism is connected to the water injection mechanism, the water injection mechanism is connected to the separation mechanism, and the collecting mechanism is connected to the cleaning mechanism. The collecting mechanism is used to collect fly ash, the water injection mechanism is used to solidify fly ash, the separation mechanism is used to separate solid and liquid from fly ash, and the cleaning mechanism is used to clean the device.

[0006] In the fly ash filtering device, the device is used to collect fly ash produced by combustion, and through a series of steps, the fly ash is turned into a slightly larger whole, which is convenient for subsequent weighing and other operations, and is convenient for realizing resource utilization of fly ash. The collecting mechanism collects scattered fly ash, and the water injection mechanism mixes fly ash and water by adding water to form a larger whole. The separation mechanism is used to separate most of the water in the fly ash, and the cleaning mechanism is used to clean the inner wall of the device, so that the fly ash and water that stick to the inner wall can fall off, keeping the inner wall of the device clean.

[0007] Furthermore, the collecting mechanism includes a collecting nozzle, a collecting pipe, a collecting box, a motor, an impeller and a driving rod. The collecting nozzle is connected to the collecting pipe, and the end of the collecting pipe away from the collecting nozzle is tightly connected to the collecting box. A collecting chamber and a driving chamber are arranged in the collecting box. The collecting chamber is divided into two upper and lower chambers by a second partition. The upper half of the collecting chamber and the driving chamber are separated by the first partition. The collecting pipe is placed in the upper half of the collecting chamber. The bottom wall of the lower half of the collecting chamber is inclined. A connecting hole is provided at the lowest point of the lower half of the collecting chamber. The collecting chamber is placed on the side close to the collecting pipe. The collecting box is tightly connected to the motor, the motor is placed in the driving chamber, the fixed end of the motor is tightly connected to the inner wall of the driving chamber, the output end of the motor is tightly connected to the driving rod, a plurality of impellers are provided, and a plurality of impellers are tightly connected to the driving rod. The impeller and the driving rod are placed in the driving chamber. The collecting box is connected to the water injection mechanism, the collecting chamber is connected to the water injection mechanism, the collecting box is connected to the separation mechanism, the collecting chamber is connected to the separation mechanism, the collecting box is connected to the cleaning mechanism, and the collecting chamber is connected to the cleaning mechanism.

[0008] In the collection mechanism, the mechanism is used to collect the surrounding fly ash so that it is concentrated in a certain place to facilitate the operation of subsequent mechanisms. In the collection mechanism, the collection box is used to store fly ash and other mechanisms. The collection box is fastened by a collection pipe and a collection nozzle. The collection box is divided into a collection chamber and a drive chamber. The collection chamber and the drive chamber are separated by a first partition. The first partition is a hollow structure with a filter screen in the middle to prevent the fly ash from entering the drive chamber during the collection of fly ash. Therefore, the collection chamber and the drive chamber are connected. The driving device is installed in the drive chamber. The motor is fastened to the inner wall of the drive chamber. The output end of the motor is fastened to a drive rod, and the drive rod is fastened to an impeller. After the motor is started, it will rotate with the drive rod, and the impeller on the drive rod will also rotate. In this process, negative pressure is generated in the collection box, and the fly ash is sucked and collected through the collection nozzle and the collection pipe. The fly ash enters the collection chamber through the collection pipe. Since the first partition is covered with a filter screen, the fly ash cannot enter the drive chamber and can only stay in the collection chamber. It is collected by other devices for subsequent operations.

[0009] Furthermore, the collecting mechanism also includes an opening and closing device, which is connected to the collecting pipe. The opening and closing device includes a fixed ring, an opening and closing plate and a telescopic rod. The fixed ring is tightly connected to the inner wall of the collecting pipe. The opening and closing plates and the telescopic rod are provided with a plurality of holes. One end of the telescopic rod is tightly connected to the fixed ring, and the end of the telescopic rod away from the fixed ring is tightly connected to the opening and closing plate. The opening and closing plate and the fixed ring are slidably connected.

[0010] In the collecting mechanism, an opening and closing device is also provided, which is used to control the amount of fly ash entering the collecting box at a single time. The amount entering is controlled by controlling the time. In the process of fly ash being collected, the fly ash enters the collecting box evenly. If the amount of fly ash entering at one time is too small, when water is added to condense it into a whole later, the small amount of fly ash may cause the whole to be small, and it will stick to other devices during the subsequent solid-liquid separation; if the amount of fly ash entering at one time is too much, after the fly ash enters the collecting box, it may cause the whole to be too large, resulting in a long drying time and reduced efficiency. Therefore, the amount of fly ash entering is controlled by controlling the opening and closing time of the collecting pipe. When the time is up, the telescopic rod extends, so that the opening and closing plate slides on the fixed ring until the gap in the middle of the fixed ring is blocked. At this time, the fly ash cannot enter the collecting cavity through the collecting pipe. When fly ash needs to enter, the telescopic rod retracts, bringing the opening and closing plate away from the center of the fixed ring. At this time, the opening and closing device opens, and fly ash can enter.

[0011] Furthermore, the water injection mechanism includes a water injection device, which is provided with two groups. The water injection device is connected to the collecting box, and the water injection device is connected to the collecting chamber. The water injection device includes a water injection pipe, a water outlet nozzle and a water storage tank. One end of the water injection pipe is tightly connected to the water outlet nozzle, and the end of the water injection pipe away from the water outlet nozzle is tightly connected to the water storage tank. The water injection pipe is tightly connected to the collecting box, the water outlet nozzle is placed in the collecting chamber, the water outlet of the water outlet nozzle faces the bottom wall of the collecting chamber, and the water storage tank is placed on the top of the collecting box.

[0012] The water injection mechanism also includes a moving device, which is provided with two groups. The two groups of moving devices are respectively connected to the two groups of water injection devices. The moving device is placed in the upper half of the collecting chamber, and the moving device is connected to the water injection pipeline. The moving device includes a first driving motor, a rotating rod, a driven block and a rotating motor. The fixed end of the first driving motor is tightly connected to the wall of the collecting chamber, the output end of the first driving motor is tightly connected to the rotating rod, the end of the rotating rod away from the first driving motor is rotatably connected to the wall of the collecting chamber, the driven block and the rotating rod are connected by threads, the rotating motor and the driven block are tightly connected, and the output end of the rotating motor is tightly connected to the water injection pipeline through a connecting rod. The water injection mechanism also includes a workbench, a rotating shaft and a reflux pipe. The workbench and the rotating shaft are both placed in the collecting chamber. There are two workbenches. The workbench is an arc-shaped structure. A water diversion channel is provided on the workbench. The two workbenches are tightly connected to the rotating shaft. The two workbenches are symmetrical about the rotating shaft. The two workbenches are respectively placed in the upper and lower chambers of the collecting chamber. The two workbenches are engaged with the second partition. The reflux pipe is connected to the water injection device. One end of the reflux pipe is tightly connected to the connecting hole of the collecting chamber, and the other end of the reflux pipe is tightly connected to the water storage tank. Both ends of the rotating shaft are rotatably connected to the wall of the collecting chamber respectively, and the rotating shaft is driven by the second drive motor.

[0013] In the water injection mechanism, the mechanism injects water toward the workbench by adjusting the angle of the water outlet nozzle, so that the water falls onto the workbench above, and the fly ash and water can be mixed. The workbench is smaller than the area of ​​the collecting chamber, and the workbench is also engaged with the second partition plate. Therefore, most of the fly ash collected in the collecting chamber will fall on the workbench after entering. The first driving motor drives the rotating rod to rotate, so that the driven block moves along the direction of the rotating rod. The bottom of the driven block is tightly connected to a rotating motor, and the output end of the rotating motor is tightly connected to the water injection pipe through a connecting rod. After the device is started, the water in the water storage tank flows out from the water outlet nozzle through the water injection pipe, first watering the workbench so that the workbench can better absorb the fly ash, and then the fly ash enters the upper half of the collecting chamber and falls onto the workbench. After that, the water outlet nozzle continuously flows water onto the workbench, so that the fly ash and water can be fully mixed. After the fly ash stops entering the collecting chamber, the first driving motor is started. , so that the rotating motor moves, and after moving to the edge of the workbench, the rotating motor starts and rotates the water injection pipe slightly to adjust the angle of water spraying, so that the fly ash on the edge of the workbench can be washed to the middle area. At the same time, a water diversion channel is provided on the workbench, and a filter is also covered in the water diversion channel. In the process of mixing water and fly ash, some excess water can be filtered out first, and the water will flow along the water diversion channel to the edge of the lower half of the collecting chamber, and the bottom of the lower half of the chamber is inclined, so the filtered water will flow along the inclined angle and flow out from the reflux pipe. There will be some impurities in the water, which will flow back to the water storage tank after purification for reuse. After completing the subsequent filtering and drying operations, the second drive motor is started to rotate the rotating shaft, and the rotating shaft and the two workbenches are tightly connected. After rotating 180°, the lower workbench is screwed up, and the upper workbench falls into the lower half of the collecting chamber. The prepared fly ash solids fall below, and this cycle is repeated.

[0014] Furthermore, the separation mechanism includes a driving hydraulic cylinder, an arc-shaped pressure plate, a conveyor belt, a fan and an electric heating pipe. The separation mechanism is placed in the collecting chamber, the fixed end of the driving hydraulic cylinder is tightly connected to the bottom wall of the collecting chamber, the output end of the driving hydraulic cylinder is tightly connected to the arc-shaped pressure plate, the fan and the collecting chamber are tightly connected to the wall on one side of the collecting pipe, the electric heating pipe is placed at the fan outlet, the fan outlet faces the workbench placed in the upper half of the collecting chamber, the conveyor belt is placed in the lower half of the collecting chamber, the conveyor belt is driven by a third driving motor, the conveyor belt is placed directly below the workbench, a fly ash outlet is provided on the wall of the collecting box away from the collecting pipe, and the conveying direction of the conveyor belt is toward the fly ash outlet.

[0015] In the separation mechanism, the mechanism is used to perform solid-liquid separation on the mixture of fly ash and water, so that most of the useless water is filtered out, leaving only water that can keep the fly ash in a solid state, and then drying it so that the water content inside it is extremely small. After drying, the fly ash is a dry solid, which is convenient for subsequent resource utilization. After the fly ash flows to the middle of the workbench, the hydraulic cylinder is driven to start, and the arc pressure plate is pressed down, so that the water in the fly ash is squeezed out and flows to the edge of the lower half of the collecting chamber through the water diversion channel. Then the hydraulic cylinder is driven to lift, and the arc pressure plate is away from the workbench. Then the fan is started to dry the fly ash that has been filtered through water. After drying, the rotating shaft rotates and rotates 180°. The workbench placed in the upper half of the collecting chamber turns to the lower half, and the workbench in the lower half turns to the upper half. The dry fly ash falls onto the conveyor belt after the workbench turns down, and is conveyed to the fly ash outlet through the conveyor belt. The workbench now located in the upper half continues the mixing and separation operations of fly ash and water.

[0016] Furthermore, the cleaning mechanism includes a cleaning scraper and a pushing hydraulic cylinder. The collecting chamber and the cleaning scraper are slidably connected. Both side walls of the collecting chamber are provided with movable grooves. Two cleaning scrapers are provided. The cleaning scrapers are provided with protrusions. The two cleaning scraper protrusions are respectively slidably connected to the two movable grooves. Two pushing hydraulic cylinders are provided. The output ends of the two pushing hydraulic cylinders are respectively fastened to the sides of the two cleaning scrapers without protrusions. The fixed end of the pushing hydraulic cylinder is fastened to the wall of the collecting chamber.

[0017] In the cleaning mechanism, this mechanism is used to clean the wall surface of the upper half of the collecting chamber. When the fly ash enters the upper half of the collecting chamber, some of it will stick to the wall surface. The fly ash on the wall surface is scraped off by the cleaning scraper and the hydraulic cylinder, so that the fly ash will reach the junction of the second partition and the wall surface. When water is injected next time, the fly ash here will be pushed to the middle of the workbench by adjusting the angle, and the water stains on the wall surface will evaporate after the drying operation.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: after the present invention is started, the fly ash is first collected. After a certain period of time, the opening and closing device is closed, and the fly ash no longer enters. In this process, the water outlet nozzle first waters the workbench to facilitate the fly ash to stick to the workbench. After the fly ash stops entering, the moving device is started, and the water injection pipe is moved and rotated to adjust the angle of the water spray to flush the fly ash to the middle area of ​​the workbench. A water diversion channel is provided on the workbench, and a filter screen is also covered in the water diversion channel. In this process, some excess water can be filtered out first, and the water flows along the water diversion channel to the edge of the lower half of the collection chamber, flows out from the return pipe, and then passes through the arc The pressure plate squeezes the moisture in the fly ash, and then the fly ash is dried by the fan and electric heating tube. After completion, the rotating shaft rotates 180°, flipping the two workbenches. The dry fly ash falls onto the conveyor belt after the workbench turns down, and is conveyed to the fly ash outlet through the conveyor belt. The upper wall of the collection chamber is cleaned by the cleaning mechanism, and the fly ash on the wall is scraped off by the cleaning scraper and the hydraulic cylinder, so that the fly ash will reach the junction of the second partition and the wall. When water is injected next time, the fly ash here is pushed to the middle of the workbench by adjusting the angle, and the fly ash and water are mixed and separated together with the fly ash entering next time.

[0023] In the fly ash filtering device, the device is used to collect fly ash produced by combustion. Through a series of steps, the fly ash is turned into a slightly larger whole, which is convenient for subsequent weighing and other operations, and is convenient for realizing resource utilization of fly ash. The collecting mechanism 1 collects scattered fly ash, and the water injection mechanism 2 mixes the fly ash and water by adding water to form a larger whole. The separation mechanism 3 is used to separate most of the water in the fly ash, and the cleaning mechanism 4 is used to clean the inner wall of the device so that the fly ash and water that stick to the inner wall can fall off, keeping the inner wall of the device clean.

[0025] In the collection mechanism 1, the mechanism is used to collect the surrounding fly ash and concentrate it in one place to facilitate the operation of subsequent mechanisms. In the collection mechanism 1, the collection box 13 is used to store fly ash and other mechanisms. The collection box 13 is fastened to the collection nozzle 11 through the collection pipe 12. The collection box 13 is divided into a collection chamber 131 and a drive chamber 132. The collection chamber 131 and the drive chamber 132 are separated by a first partition. The first partition is a hollow structure with a filter screen in the middle to prevent the fly ash from entering the drive chamber 132 during the collection of fly ash. Therefore, the collection chamber 131 and the drive chamber 132 are connected, and the driving device is installed in the drive chamber 132. The motor 14 is tightly connected to the inner wall of the driving chamber 132, and the output end of the motor 14 is tightly connected to the driving rod 16, and the driving rod 16 is tightly connected to the impeller 15. After the motor 14 is started, it will drive the driving rod 16 to rotate, and the impeller 15 on the driving rod 16 will also rotate. During this process, negative pressure is generated in the collecting box 13, and the fly ash is sucked and collected through the collecting nozzle 11 and the collecting pipe 12. The fly ash enters the collecting chamber 131 through the collecting pipe 12. Since the first partition plate is covered with a filter screen, the fly ash cannot enter the driving chamber 132 and can only stay in the collecting chamber 131 and be collected by other devices for subsequent operations.

The amount entering is controlled by controlling the time. In the process of fly ash collection, the fly ash enters the collection box 13 evenly. If the amount of fly ash entering at one time is too small, when water is added to form a whole later, the whole molding may be small due to the small amount of fly ash, and it may stick to other devices during the subsequent solid-liquid separation.

[0032] In the separation mechanism 3, the mechanism is used to separate the mixture of fly ash and water into solid and liquid, so that most of the useless water is filtered out, leaving only the water that can keep the fly ash in a solid state, and then drying it to make its internal water content very small. After the fly ash is dried, it is a dry solid, which is convenient for subsequent resource utilization. After the fly ash flows to the middle of the workbench 23, the hydraulic cylinder 31 is driven to start, and the arc pressure plate 32 is pressed down, so that the water in the fly ash is squeezed out and flows to the edge of the lower half of the collection chamber 131 through the water channel. , then the hydraulic cylinder 31 is driven to lift, the arc pressure plate 32 moves away from the workbench 23, and then the fan 34 is started to dry the fly ash that has been filtered through water. After drying, the rotating shaft 24 rotates and rotates 180°. The workbench 23 placed in the upper half of the collecting chamber 131 is transferred to the lower half, and the workbench 23 in the lower half is transferred to the upper half. After the workbench 23 is transferred down, the dried fly ash falls onto the conveyor belt 33 and is transported out of the fly ash outlet 133 through the conveyor belt 33. The workbench 23 now located in the upper half continues to mix and separate the fly ash and water.

[0033] The cleaning mechanism 4 includes a cleaning scraper 41 and a pushing hydraulic cylinder 42. The collecting chamber 131 and the cleaning scraper 41 are slidably connected. Both side walls of the collecting chamber 131 are provided with movable grooves 134. There are two cleaning scrapers 41. A protrusion is provided on the cleaning scraper 41. The protrusions of the two cleaning scrapers 41 are respectively slidably connected to the two movable grooves 134. There are two pushing hydraulic cylinders 42. The output ends of the two pushing hydraulic cylinders 42 are respectively fastened to the sides of the two cleaning scrapers 41 without protrusions. The fixed end of the pushing hydraulic cylinder 42 is fastened to the wall of the collecting chamber 131.

[0034] In the cleaning mechanism 4, the mechanism is used to clean the wall surface of the upper half of the collecting chamber 131. When the fly ash enters the upper half of the collecting chamber 131, some of it will stick to the wall surface. The fly ash on the wall surface is scraped off by the cleaning scraper 41 and the pushing hydraulic cylinder 42, so that the fly ash will reach the junction of the second partition and the wall surface. When water is injected next time, the fly ash here will be pushed to the middle of the workbench 23 by adjusting the angle, and the water stains on the wall surface will evaporate after the drying operation.

[0035] Working principle of the present invention: After the present invention is started, the fly ash is first collected. After a certain period of time, the opening and closing device 17 is closed, and the fly ash no longer enters. In this process, the water outlet nozzle 212 first waters the workbench 23 to facilitate the fly ash to stick to the workbench 23. After the fly ash stops entering, the moving device 22 is started, and the water injection pipe 211 moves and rotates, and the angle of water spraying is adjusted to flush the fly ash to the middle area of ​​the workbench 23. A water diversion channel is provided on the workbench 23, and a filter screen is also covered in the water diversion channel. In this process, some excess water can be filtered out first, and the water flows along the water diversion channel to the edge of the lower half of the collection chamber 131, flows out from the reflux pipe, and then squeezes the fly ash through the arc pressure plate 32. The fly ash is dried by the fan 34 and the electric heating tube 35. After completion, the rotating shaft 24 rotates and rotates 180 degrees to flip the two workbenches 23. The dry fly ash falls onto the conveyor belt 33 after the workbench 23 turns down, and is transmitted to the fly ash outlet 133 by the conveyor belt 33. The upper wall surface of the collecting chamber 131 is cleaned by the cleaning mechanism 4, and the fly ash on the wall is scraped off by the cleaning scraper 41 and the pushing hydraulic cylinder 42, so that the fly ash reaches the junction of the second partition and the wall. When water is injected next time, the fly ash here is pushed to the middle of the workbench 23 by adjusting the angle, and the fly ash and water are mixed and separated together with the fly ash entering next time.
