Description

Technical Field

[0001] This invention relates to the field of resource recycling technology, and in particular to a heavy metal enrichment plant treatment device. Background Technology

[0002] Heavy metal accumulating plants are plants that absorb and accumulate heavy metals from sediments. Accumulation coefficients can be used to reflect the degree or strength of a plant's ability to accumulate heavy metals. To address soil pollution, researchers cultivate heavy metal hyperaccumulating plants to absorb heavy metals from the soil and transport them to the above-ground parts of the plants. The mature, high-accumulation plants are then harvested to remove heavy metals from the soil.

[0003] Currently, heavy metal accumulating plants are mostly treated by incineration. This method can reduce the storage space of the plants and concentrate the heavy metal content, which is conducive to the normal operation of subsequent recycling. However, during the incineration process, heavy metal accumulating plants are difficult to burn completely. This means that workers need to put the incompletely burned heavy metal accumulating plants back into the incineration device for further incineration. This not only increases the labor intensity of the workers, but also slows down the processing efficiency of heavy metal accumulating plants, resulting in a significant increase in the processing cost of heavy metal accumulating plants. Summary of the Invention

[0004] The purpose of this invention is to provide a heavy metal accumulating plant treatment device to solve the above-mentioned problems, thereby improving the poor incineration effect of heavy metal accumulating plant incineration devices and slowing down the treatment efficiency of heavy metal accumulating plants.

[0005] The present invention achieves the above-mentioned objective through the following technical solution: a heavy metal enrichment plant treatment device includes a shell, two burners fixedly connected inside the shell, a combustion-supporting device installed on one side of the inner wall of the shell, one end of the combustion-supporting device extending to the outside of the shell, a cooling device installed inside the shell, the cooling device being connected to the shell via a water outlet pipe, an oxygenation device fixedly connected to one end of the cooling device, one end of the oxygenation device sequentially penetrating the cooling device and the shell and fixedly connected to one side of the inner wall of the shell, a secondary treatment device fixedly connected to the inner top wall of the shell, the top end of the secondary treatment device penetrating the shell and extending into the interior of the oxygenation device, and a dust collection box inserted into the surface of the shell below the oxygenation device, one end of the dust collection box penetrating the shell and inserted into the shell;

[0006] The combustion-supporting device includes a bearing cylinder rotatably connected to the inner wall of the housing.

[0008] Preferably, the inner wall of the housing is fixedly connected to a first scraper disposed inside the bearing cylinder, and the top end of the first scraper contacts the inner surface of the bearing cylinder.

[0009] Preferably, the bearing cylinder is rotatably connected to a protective cover that is fixedly connected to the housing, the gear ring and the gear are both disposed inside the protective cover, and the output shaft of the first motor passes through the protective cover and is fixedly connected to the gear.

[0010] Preferably, a cooling chamber is provided inside the shell, and the cooling device includes a cooling tower located at the rear of the shell. A liquid pump connected to the surface of the cooling tower is fixedly connected to the cooling tower. One end of the liquid pump passes through the shell and extends into the interior of the cooling chamber. A water outlet pipe connected to the top of the cooling tower is fixedly connected to the cooling tower. One end of the water outlet pipe passes through the shell and extends into the interior of the cooling chamber. Both the interior of the cooling chamber and the cooling tower are filled with heat transfer oil.

[0011] Preferably, the oxygenation device includes a fan located behind the cooling tower. One end of the fan is fixedly connected to a three-way valve that communicates with the fan's outlet. The three-way valve is fixedly connected to one end of the housing. The bottom end of the three-way valve is fixedly connected to two air guide pipes, each communicating with the three-way valve. One end of each air guide pipe penetrates the housing and is fixedly connected to one side of the inner wall of the housing. The surface of each air guide pipe is fixedly connected to nozzles that are evenly distributed and communicate with the air guide pipe.

[0012] Preferably, the inner wall of the housing is fixedly connected to two support frames, both located below the bearing cylinder. One end of each support frame is fixedly connected to a uniformly distributed air guide tube. The cross-sectional shape of the air guide tube is an isosceles trapezoid. The upper opening diameter of the air guide tube is larger than the lower opening diameter. One end of the nozzle extends into the interior of the air guide tube.

[0013] Preferably, a heat exchange tube is fixedly connected between the fan and the three-way valve. The two ends of the heat exchange tube are respectively connected to the fan and the three-way valve. One end of the heat exchange tube passes through the cooling tower and extends to the outside of the cooling tower. The heat exchange tube is spiral in shape.

[0014] Preferably, the secondary treatment device includes a cyclone dust collector tower disposed at the rear of the housing.

[0016] The beneficial effects of this invention are:

[0017] (1) By setting up a combustion-supporting device, when the processing device is running normally, the first motor drives the bearing cylinder to rotate at a constant speed through gears and gear rings. The bearing cylinder continuously turns over the heavy metal-rich plants, so there is no need to worry about the heavy metal-rich plants accumulating inside the bearing cylinder, so that the heavy metal-rich plants being burned can fully contact the air, thereby improving the burning effect of the heavy metal-rich plants.

[0018] (2) By setting a discharge port, only heavy metal accumulating plants whose volume after combustion is smaller than the diameter of the discharge port can pass through the discharge port smoothly. This can prolong the residence time of heavy metal accumulating plants in the support cylinder and further increase the combustion effect of heavy metal accumulating plants. At the same time, the design of the discharge port with the opening near the guide ring being smaller than the opening far from the guide ring can reduce the probability of heavy metal accumulating plant ash getting stuck inside the discharge port, thereby achieving a good guiding effect.

[0019] (3) By setting up an oxygenation device, the blower can guide the oxygen-containing air from the outside to the inside of the three-way valve. The three-way valve guides the oxygen-containing air to the inside of the two air guide pipes respectively. The air guide pipes guide the oxygen-containing air to the nozzles. The nozzles spray the oxygen-containing air into the inside of the carrier cylinder, so that the oxygen-containing air comes into contact with the heavy metal accumulating plants, which increases the oxygen content inside the carrier cylinder and makes the heavy metal accumulating plants burn more completely.

[0020] (4) By setting up an air guide, the air guide can accurately guide the oxygen-containing air sprayed from the nozzle to the vicinity of the heavy metal-accumulating plant, so that the oxygen-containing air can quickly and effectively react with the heavy metal-accumulating plant, further improving the incineration effect on the heavy metal-accumulating plant.

[0021] (5) By using the cooling device in conjunction with the heat exchange tube, the heat transfer oil will preheat the air as it passes through the heat exchange tube. There is no need to worry about the air entering the shell being too cold, which would reduce the combustion temperature. This ensures the combustion efficiency of heavy metal-rich plants. The spiral design of the heat exchange tube can extend the time for the air to pass through the heat exchange tube, allowing the air to be fully preheated by the heat transfer oil. Furthermore, the device uses the waste heat generated during combustion to preheat the air. This not only eliminates the need for additional heating devices for preheating but also effectively utilizes waste heat resources to reduce the overall power consumption of the device.

[0022] (6) By setting up a secondary treatment device, when the hot air containing heavy metal-enriched plant ash can enter the cyclone dust collector through the dust guide pipe, the cyclone dust collector uses its own characteristics to separate the hot air and heavy metal-enriched plant ash, and the outlet pipe guides the hot air back into the fan, so that the hot air is heated and drawn into the oxygen-containing air inside the fan, further reducing the unnecessary waste of waste heat resources, thereby achieving the effect of recycling.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] In practical implementation: such as Figure 1-8As shown, a heavy metal enrichment plant treatment device includes a shell 1. Two burners 2 are fixedly connected inside the shell 1. A combustion-supporting device 3 is installed on one side of the inner wall of the shell 1, with one end of the combustion-supporting device 3 extending to the outside of the shell 1. A cooling device 4 is installed inside the shell 1, connected to the shell 1 via a water outlet pipe 403. An oxygenation device 5 is fixedly connected to one end of the cooling device 4, with one end of the oxygenation device 5 passing through the cooling device 4 and the shell 1 and fixedly connected to one side of the inner wall of the shell 1. A secondary treatment device 6 is fixedly connected to the inner top wall of the shell 1, with its top end penetrating the shell 1 and extending into the interior of the oxygenation device 5. A dust collection box 7, located below the oxygenation device 5, is inserted into the surface of the shell 1, with one end of the dust collection box 7 penetrating the shell 1 and inserted into it. The combustion-supporting device 3 includes a support cylinder 301 rotatably connected to the inner wall of the shell 1. The surface of the support cylinder 301 has annularly distributed material discharge ports 302. A gear ring 303 is fixedly connected to one side of the discharge port 302. A gear 304 is meshed with the lower surface of the gear ring 303. A first motor 305 is fixedly connected to one end of the gear 304. One end of the first motor 305 passes through the outside of the housing 1 and is fixedly connected to one end of the housing 1. When the processing device is running normally, the first motor 305 drives the bearing cylinder 301 to rotate at a constant speed through the gear 304 and the gear ring 303. The bearing cylinder 301 continuously turns over the heavy metal-rich plants. There is no need to worry about the heavy metal-rich plants accumulating inside the bearing cylinder 301. This allows the heavy metal-rich plants to be burned to have sufficient contact with the air, thereby improving the burning effect of the heavy metal-rich plants. Furthermore, due to the presence of the discharge port 302, only heavy metal-rich plants whose volume after burning is smaller than the diameter of the discharge port 302 can pass through the discharge port 302 smoothly. This can prolong the residence time of the heavy metal-rich plants in the bearing cylinder 301, further increasing the burning effect of the heavy metal-rich plants.Two guide rings 306 are fixedly connected to the inner surface of the bearing cylinder 301. The two guide rings 306 are respectively disposed on both sides of the discharge port 302. The opposite sides of the two guide rings 306 are in no pressure contact with the shell 1. The cross-sectional shape of the guide rings 306 is a right triangle. The inclined surfaces of the two guide rings 306 are disposed on the side near the discharge port 302. The cross-sectional shape of the discharge port 302 is an isosceles trapezoid. The opening of the discharge port 302 near the guide rings 306 is smaller than the opening of the discharge port 302 away from the guide rings 306. The guide ring 306 reduces the probability of heavy metal accumulating plants falling onto the connection between the shell 1 and the support cylinder 301, thereby reducing the probability of the support cylinder 301 being obstructed from rotating. Simultaneously, the guide ring 306 can also guide the ash from the heavy metal accumulating plants into the discharge port 302, reducing the probability of the ash remaining inside the support cylinder 301. This achieves the dual beneficial effects of blocking and guiding. The design incorporates a smaller opening near the guide ring 306 than the opening further away from it. This reduces the probability of heavy metal-accumulating plant matter getting stuck inside the discharge port 302, thus achieving a good guiding effect; a first scraper 307 is fixedly connected to the inner wall of the shell 1 and disposed inside the bearing cylinder 301. The top of the first scraper 307 contacts the inner surface of the bearing cylinder 301. The first scraper 307 can scrape off the heavy metal-accumulating plants adhering to the inner surface of the bearing cylinder 301, so that the discharge port 302 remains unobstructed, thus achieving a good self-cleaning effect; the surface of the bearing cylinder 301 is connected to a device fixed to the shell 1. The protective cover 308, gear ring 303, and gear 304 are all located inside the protective cover 308. The output shaft of the first motor 305 passes through the protective cover 308 and is fixedly connected to the gear 304. The protective cover 308 can separate the gear 304 and gear ring 303 from the heavy metal-accumulating plant ash inside the housing 1, reducing the probability of the heavy metal-accumulating plant ash falling onto the surface of the gear 304 or gear ring 303, thus ensuring that the first motor 305 can normally drive the bearing cylinder 301 to rotate, thereby achieving a good protective effect.

[0034] like Figure 2 and Figure 3As shown, a cooling chamber 101 is provided inside the shell 1. The cooling device 4 includes a cooling tower 401 located behind the shell 1. A liquid pump 402, which communicates with the cooling tower 401, is fixedly connected to the surface of the cooling tower 401. One end of the liquid pump 402 penetrates the shell 1 and extends into the interior of the cooling chamber 101. A water outlet pipe 403, which communicates with the cooling tower 401, is fixedly connected to the top of the cooling tower 401. One end of the water outlet pipe 403 penetrates the shell 1 and extends into the interior of the cooling chamber 101. The cooling chamber 101 and the cooling tower 401... The interior of the cooling chamber 101 is filled with heat transfer oil. While the burner 2 is burning the heavy metal enrichment plants normally, the heat transfer oil inside the cooling chamber 101 can absorb the temperature inside the shell 1 to reduce the probability of the high temperature inside the shell 1 being conducted to the outside. While the heat transfer oil absorbs heat, the infusion pump 402 delivers the cooler heat transfer oil inside the cooling tower 401 into the interior of the cooling chamber 101. This can reduce the overall heat of the heat transfer oil inside the cooling chamber 101 and ensure that the heat transfer oil inside the cooling chamber 101 can always absorb the heat inside the shell 1.

[0035] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the oxygenation device 5 includes a fan 501 located behind the cooling tower 401. One end of the fan 501 is fixedly connected to a three-way valve 502 that communicates with the air outlet of the fan 501. The three-way valve 502 is fixedly connected to one end of the housing 1. The bottom end of the three-way valve 502 is fixedly connected to two air guide pipes 503, both of which communicate with the three-way valve 502. One end of the air guide pipe 503 penetrates the housing 1 and is fixedly connected to one side of the inner wall of the housing 1. The surface of the air guide pipe 503 is fixedly connected to nozzles 504 that are evenly distributed and communicate with the air guide pipe 503. The fan 501 can guide oxygenated air from the outside to the inside of the three-way valve 502. The three-way valve 502 guides oxygen-containing air into the interiors of two air guide pipes 503, which in turn guide the oxygen-containing air into nozzles 504. The nozzles 504 then spray the oxygen-containing air into the interior of the support cylinder 301, allowing the oxygen-containing air to contact the heavy metal accumulating plants and increasing the oxygen content inside the support cylinder 301, thus enabling more complete combustion of the heavy metal accumulating plants. Two support frames 505 are fixedly connected to the inner wall of the shell 1, both positioned below the support cylinder 301. One end of each support frame 505 is fixedly connected to evenly distributed air guide ducts 506. The cross-sectional shape of the air guide ducts 506 is an isosceles trapezoid. The upper opening diameter is larger than the lower opening diameter of the air guide duct 506. One end of the nozzle 504 extends into the interior of the air guide duct 506. The air guide duct 506 can accurately guide the oxygen-containing air ejected from the nozzle 504 to the vicinity of the heavy metal accumulating plant, so that the oxygen-containing air can quickly and effectively react with the heavy metal accumulating plant, further improving the incineration effect on the heavy metal accumulating plant. A heat exchange tube 507 is fixedly connected between the fan 501 and the three-way valve 502. Both ends of the heat exchange tube 507 are connected to the fan 501 and the three-way valve 502 respectively. One end of the heat exchange tube 507 penetrates through the cooling tower 401 and extends to the outside of the cooling tower 401. The shape of 507 is spiral. When the mixed air passes through the heat exchange tube 507, the heat transfer oil will preheat the air. There is no need to worry about the air entering the shell 1 being too cold, which would lead to a decrease in combustion temperature. This ensures the combustion efficiency of heavy metal-rich plants. The spiral design of the heat exchange tube 507 can extend the time for the air to pass through the heat exchange tube 507, so that the air can be fully preheated by the heat transfer oil. Moreover, the device uses the waste heat generated during combustion to preheat the air. This not only eliminates the need for additional heating devices for preheating, but also effectively utilizes waste heat resources to reduce the overall power consumption of the device.

[0036] like Figure 3 and Figure 8As shown, the secondary treatment device 6 includes a cyclone dust collector 601 located behind the housing 1. A dust guide pipe 602, communicating with the cyclone dust collector 601, is fixedly connected to the surface of the cyclone dust collector 601. One end of the dust guide pipe 602 penetrates the top of the housing 1 and communicates with it. An air outlet pipe 603, communicating with the cyclone dust collector 601, is fixedly connected to the top of the cyclone dust collector 601. One end of the air outlet pipe 603 is connected to the air inlet of the fan 501. When hot air containing heavy metal-rich plant ash enters the cyclone dust collector 601 through the dust guide pipe 602, the cyclone dust collector 601 uses its own characteristics to separate the hot air and the heavy metal-rich plant ash. The air outlet pipe 603 then guides the hot air back into the fan 501, heating the oxygen-containing air drawn into the fan 501, further reducing waste heat resources. This avoids unnecessary waste, thus achieving a recycling effect. A filter screen 604 is embedded at the bottom of the air outlet pipe 603, and a second motor 605 is fixedly connected to the top of the cyclone dust collector tower 601. The output shaft of the second motor 605 passes through the interior of the cyclone dust collector tower 601, and a second scraper 606 is fixedly connected to the output shaft of the second motor 605. The top of the second scraper 606 contacts the filter screen 604. When hot air enters the air outlet pipe 603, the filter screen 604 can filter out solid impurities in the hot air, thereby reducing the probability of dust-laden hot air clogging the oxygenation device 5, thus achieving an anti-clogging effect. While the filter screen 604 is filtering hot air, the second motor 605 can drive the second scraper 606 to reciprocate to scrape off the impurities adhering to the surface of the filter screen 604, keeping the filter screen 604 unobstructed, thus achieving a self-cleaning effect.

[0037] When the processing device is operating normally, the burner 2 incinerates the heavy metal-rich plants placed inside the support cylinder 301 through the feed inlet 302. At the same time, the first motor 305 drives the gear 304 to rotate at a constant speed, the gear 304 drives the gear ring 303 to rotate at a constant speed, the gear ring 303 drives the support cylinder 301 to rotate at a constant speed, and the support cylinder 301 drives the heavy metal-rich plants to rotate at a constant speed. The heavy metal-rich plants are constantly turned over inside the support cylinder 301, so there is no need to worry about the heavy metal-rich plants accumulating inside the support cylinder 301. This allows the incinerated heavy metal-rich plants to have sufficient contact with the air, thereby improving the incineration effect. Furthermore, due to the presence of the feed inlet 302, only heavy metal-rich plants with a volume smaller than the diameter of the feed inlet 302 after combustion can pass through the feed inlet 302 smoothly. This can prolong the residence time of the heavy metal-rich plants in the support cylinder 301, further increasing the incineration effect of the heavy metal-rich plants.

[0038] While the burner 2 is burning heavy metal-rich plants normally, the heat transfer oil inside the cooling chamber 101 can absorb the temperature inside the shell 1 to reduce the probability of the high temperature inside the shell 1 being conducted to the outside. While the heat transfer oil absorbs heat, the infusion pump 402 delivers the cooler heat transfer oil inside the cooling tower 401 into the cooling chamber 101. This can reduce the overall heat of the heat transfer oil inside the cooling chamber 101, ensuring that the heat transfer oil inside the cooling chamber 101 can always absorb the heat inside the shell 1. At the same time, the heat transfer oil entering the cooling chamber 101 will guide the heat transfer oil on the upper part of the cooling chamber 101 back to the cooling tower 401 through the water outlet pipe 403. When this part of the warmer heat transfer oil enters the cooling tower 401, it can heat the air inside the heat exchange tube 507 to preheat the air entering the shell 1. There is no need to worry about the air entering the shell 1 being too cold, which would lead to a decrease in the combustion temperature, thus ensuring the combustion efficiency of heavy metal-rich plants.

[0039] While burner 2 is normally incinerating heavy metal-rich plants, hot air containing heavy metal-rich plant ash can enter cyclone dust collector 601 through dust guide pipe 602. Cyclone dust collector 601 guides this hot air to rotate, using centrifugal force to separate the heavy metal-rich plant ash from the hot air and collect it on the wall of cyclone dust collector 601. Then, cyclone dust collector 601 uses gravity to guide the heavy metal-rich plant ash to the inner bottom wall of cyclone dust collector 601 for subsequent cleaning work. Because the density of hot air is lower than that of normal temperature air, the hot air can be guided into the interior of fan 501 through exhaust pipe 603. Fan 501 mixes the hot air with the oxygen-containing air from the outside and... Air is introduced into heat exchange tube 507. As the mixed air passes through heat exchange tube 507, the heat transfer oil preheats the air. The heated mixed air is then guided by heat exchange tube 507 to three-way valve 502. Three-way valve 502 guides the heated mixed air to the interior of two air guide pipes 503. Air guide pipes 503 guide the heated mixed air to nozzles 504. Nozzles 504 spray the heated mixed air onto the inner wall of air guide duct 506. Air guide duct 506 then guides the heated mixed air to the interior of bearing cylinder 301, allowing the heated mixed air to come into contact with the heavy metal accumulating plants, increasing the oxygen content inside bearing cylinder 301, and enabling the heavy metal accumulating plants to be burned more completely.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
