Description

Technical Field

[0001] This invention relates to the field of plasma spraying technology, specifically to a solid waste treatment device and method for undeposited materials from plasma spraying of artificial bones. Background Technology

[0002] Plasma spraying technology is a key process for manufacturing core functional layers of artificial bone implants, such as hydroxyapatite bioactive coatings and wear-resistant zirconia ceramic layers. This technology uses high-temperature plasma jets to melt or partially melt powder materials and spray them at high speed onto the substrate surface to form a dense coating. However, significant challenges exist in practical operation: During plasma spraying, some powder, especially fine particles or particles with deviated spray trajectory, fails to be effectively deposited on the target substrate, becoming "oversprayed" dust. These "oversprayed" powders exhibit a special physical morphology: extremely small particle size, generally in the range of tens of nanometers to tens of micrometers, with extremely high specific surface area and surface activity, and excellent dispersibility, making them easy to generate dust. Such ultrafine powder waste poses a severe challenge to traditional solid waste treatment methods.

[0003] During the spraying process, undeposited ultrafine dust escapes into the working environment, forming inhalable particulate matter. Long-term exposure to this environment poses a health risk to operators, including respiratory diseases such as pneumoconiosis, lung inflammation, and even systemic inflammatory responses. Simultaneously, the fugitive emission of dust also contaminates the cleanliness of the workshop.

[0004] Existing industrial dust collection equipment, such as existing dust collectors and settling chambers, is primarily designed to remove dust and ensure a clean production environment, with almost no consideration given to key aspects such as the decomposition, sterilization, and purification of the collected materials. There is currently no dedicated solid waste treatment device on the market specifically designed for plasma-sprayed "oversprayed" bioceramic powder, capable of achieving integrated closed-loop collection, treatment, and re-purification of solid waste. Therefore, we provide a solid waste treatment device and method for undeposited materials from plasma-sprayed artificial bones to solve the aforementioned problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: A solid waste treatment device for undeposited material from plasma spraying of artificial bones includes a frame, on which a cyclone separator is provided for centrifugally separating large particles from the dust generated during spraying. An air inlet pipe is provided on the cyclone separator, and a turbulence mechanism is provided inside the cyclone separator for turbulenting and agglomerating fine particles in the dust.

The crucible is located inside the heating chamber, and an electric heating wire for heating the crucible is provided on the outer wall of the crucible. An incinerator is installed on the frame, and an exhaust mechanism is installed on the frame. The exhaust mechanism is used to extract the gas that has been heated and decomposed inside the heating chamber into the incinerator for combustion.

[0008] As described above, a solid waste treatment device for undeposited materials from plasma spraying of artificial bones: the first rotating rod and the second rotating rod are connected by a first transmission mechanism, and the first rotating rod rotates and drives the second rotating rod to rotate synchronously. The first transmission mechanism includes a first sprocket mounted on a first rotating rod and a second sprocket mounted on a second rotating rod, with the first sprocket and the second sprocket connected by a chain drive.

[0009] A solid waste treatment device for undeposited material from plasma spraying of artificial bones, as described above: the bottom of the cyclone separator is connected to a discharge cylinder that communicates with the interior of the heating chamber. The discharge cylinder extends into the interior of the heating chamber and the discharge port is located above the crucible. A valve for controlling the opening and closing of the internal passage of the discharge cylinder is installed on the discharge cylinder.

[0010] A solid waste treatment device for undeposited materials from plasma spraying of artificial bones, as described above: a main shaft is rotatably mounted on the frame, and the main shaft and a first rotating rod are driven by a second transmission mechanism. When the main shaft rotates, it will drive the first rotating rod to rotate synchronously. A motor is mounted on the frame, and the output end of the motor is connected to the main shaft through a coupling to drive the main shaft to rotate. The second transmission mechanism includes a bevel gear ring mounted on the main shaft and a bevel gear mounted on the first rotating rod, wherein the bevel gear ring meshes with the bevel gear.

[0011] A solid waste treatment device for undeposited material from plasma spraying of artificial bones, as described above: The air extraction mechanism includes a piston cylinder mounted on a frame, a piston rod movably inserted into the piston cylinder, a piston rod being mounted on the piston cylinder and movably engaged with the piston cylinder, an air intake pipe communicating with the interior of the heating chamber and an exhaust pipe communicating with the interior of the incinerator being mounted on the piston cylinder, the piston rod and the main shaft being driven by a third transmission mechanism, the main shaft rotating causing the piston rod to slide up and down inside the piston cylinder.

[0012] A solid waste treatment device for plasma-sprayed undeposited material of artificial bone as described above: the third transmission mechanism includes a turntable mounted on the main shaft, and a swing arm is provided between the turntable and the piston rod, with the two ends of the swing arm respectively hinged to the turntable and the piston rod.

[0013] A solid waste treatment device for plasma-sprayed undeposited material of artificial bone as described above: a first one-way valve is installed on the suction pipe, which only allows gas inside the heating chamber to enter the piston cylinder in one direction through the second rotating rod; a second one-way valve is installed on the exhaust pipe, which only allows gas inside the piston cylinder to enter the incinerator in one direction through the exhaust pipe.

[0014] A method for treating solid waste from plasma-sprayed undeposited materials of artificial bones includes the following steps: S1. During the plasma spraying process, some powder fails to be effectively deposited on the target substrate and becomes "oversprayed" dust. The oversprayed dust is tangentially introduced into the cyclone separator through the air intake pipe to form a high-speed vortex. Large solid particles are separated by centrifugal force and fall off the cylinder wall of the cyclone separator. At the same time, fine particles are also agglomerated and enlarged into large particles by the high-frequency vibration of the baffle plate, and finally fall to the bottom of the cyclone separator. S2, open the valve on the discharge cylinder, and the solid particles separated by the cyclone separator enter the crucible inside the heating chamber. Turn on the electric heating wire to heat the crucible, and continuously introduce nitrogen into the heating chamber during heating to decompose the solid particles inside the crucible. The gas produced by decomposition is extracted into the incinerator through the gas extraction mechanism. S3, the gases produced by final decomposition are converted into clean gases through combustion inside the incinerator before being emitted to the outside. Compared with the prior art, the beneficial effects of the present invention are: In use, the oversprayed dust enters the cyclone separator tangentially through the air inlet pipe, forming a high-speed vortex. This causes large solid particles in the oversprayed dust to be separated by centrifugal force and fall against the cylinder wall of the cyclone separator, thus rapidly separating and collecting the large solid waste particles in the oversprayed dust. Inside the cyclone separator, a first rotating rod is installed, with a baffle plate on it. The baffle plate is equipped with piezoelectric ceramic plates. Applying a high-frequency pulsed current to the piezoelectric ceramic plates causes the baffle plate to generate high-frequency micro-vibration, which disturbs the airflow. For fine particles in the dust, centrifugal force alone is insufficient to separate them. The high-frequency micro-vibration of the baffle plate disrupts the original stable streamlined motion trajectory of the fine particles, increasing the chance of collision between the disturbed particles. During the collision, the particles agglomerate and merge, forming larger particles. These larger particles are then effectively thrown against the cylinder wall by centrifugal force and captured. Therefore, this invention can fully capture and collect solid particles in oversprayed dust. The separated solid particulate waste enters the crucible inside the heating chamber through the discharge cylinder. The electric heating wire is turned on to heat the crucible, and nitrogen is continuously introduced into the heating chamber during heating. This causes the solid particulate matter inside the crucible to decompose into most of the inorganic matter. The high temperature also sterilizes the solid particulate matter. At the same time, the gas produced by decomposition is extracted by the gas extraction mechanism and sent to the incinerator for further combustion and conversion into clean gas before being discharged to the outside. Therefore, this invention designs a special solid waste treatment device that integrates closed-loop collection, treatment, and re-purification of solid waste. It can effectively collect solid waste from the overspray dust formed during the plasma spraying process of artificial bones where no material has been deposited. At the same time, it can further decompose, sterilize, and purify the collected solid waste at high temperature, so that the solid waste is effectively treated and will not cause pollution to the environment, thus solving the problem of damage to the surrounding environment and human health.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Please see Figures 1-10As an embodiment of the present invention, a solid waste treatment device for undeposited material of plasma spraying of artificial bone includes a frame 1, on which a cyclone separator 2 is provided for centrifugally separating large particles in the dust generated during spraying. An air inlet pipe 3 is provided on the cyclone separator 2, and a turbulence mechanism is provided inside the cyclone separator 2 for turbulenting and agglomerating fine particles in the dust. A heating chamber 7 is provided on the frame 1. The bottom of the cyclone separator 2 is connected to the interior of the heating chamber 7. A second rotating rod 8 is rotatably provided on the heating chamber 7. A crucible 9 is provided on the second rotating rod 8 for collecting the solid particles separated inside the cyclone separator 2. The crucible 9 is located inside the heating chamber 7. An electric heating wire 10 for heating the crucible 9 is provided on the outer wall of the crucible 9. An incinerator 27 is installed on the frame 1, and an exhaust mechanism is installed on the frame 1. The exhaust mechanism is used to extract the gas after heating and decomposition inside the heating chamber 7 into the incinerator 27 for incineration.

[0028] In this embodiment, during use, the oversprayed dust enters the cyclone separator 2 tangentially through the air inlet pipe 3, forming a high-speed vortex. This causes large solid particles in the oversprayed dust to be separated by centrifugal force and fall against the cylinder wall of the cyclone separator 2, thereby rapidly separating and collecting the large solid waste particles in the oversprayed dust. The top of the cyclone separator 2 is open, and the purified gas after separating the solid particles is discharged outward through the top opening. Furthermore, a turbulence mechanism is set inside the cyclone separator 2 to turbulent the airflow by generating high-frequency micro-vibrations. For fine particles in the dust, centrifugal force alone is insufficient to separate them. The high-frequency micro-vibrations of the turbulence mechanism disrupt the original stable streamlined motion trajectory of the fine particles, increasing the chance of collisions between the disturbed particles. During the collisions, the particles agglomerate and merge, forming larger particles. These larger particles are then effectively thrown against the cylinder wall by centrifugal force and captured. Therefore, the solid particles in the oversprayed dust can be fully captured and collected. The separated solid particulate waste enters the crucible 9 inside the heating chamber 7. The electric heating wire 10 is spirally arranged around the outer wall of the crucible 9. The electric heating wire 10 is electrically connected to an external power source through a wire. The electric heating wire 10 is turned on to heat the crucible 9. The heating chamber 7 is equipped with an air inlet pipe for filling the interior with nitrogen. During heating, nitrogen is continuously introduced into the heating chamber 7, causing the solid particulate matter inside the crucible 9 to decompose into most of the inorganic matter. The solid particulate matter is mainly hydroxyapatite, so the decomposition reaction of hydroxyapatite mainly occurs, producing inorganic matter such as tricalcium phosphate and tetracalcium phosphate. At the same time, the gases produced by decomposition are mainly water and CO produced by incomplete combustion. The gases are then extracted by the gas extraction mechanism to the incinerator 27 for further incineration. After incineration, the gases are converted into clean gases before being discharged to the outside, thus not causing pollution to the environment.

[0029] It should be noted that the heating chamber 7 is equipped with a maintenance door by means of a hinge, which is convenient to open the maintenance door after the device is used to remove the inorganic matter and waste generated inside the crucible 9. The top of the incinerator 27 is equipped with an exhaust chimney 28, through which the purified gas after combustion inside the incinerator 27 is discharged to the outside.

[0030] As a further embodiment of the present invention, the turbulence mechanism includes a first rotating rod 4 rotatably mounted on the cyclone separator 2, a plurality of turbulence plates 5 mounted on the first rotating rod 4, and a plurality of piezoelectric ceramic plates 6 mounted on the turbulence plates 5.

[0031] In this embodiment, when the first rotating rod 4 rotates, it drives multiple baffles 5 to rotate, which in turn drives multiple piezoelectric ceramic plates 6 on the baffles 5 to rotate. A high-frequency pulsed current is applied to the piezoelectric ceramic plates 6, causing the baffles 5 to generate high-frequency micro-vibrations to disturb the airflow. For fine particles in the dust, centrifugal force alone is insufficient to separate them. By disrupting the original stable streamlined motion trajectory of the fine particles through the high-frequency micro-vibrations of the baffles 5, the chance of collision between the disturbed particles is increased, causing them to stick together and merge during the collision, forming larger particles. Thus, the centrifugal force effectively throws these larger particles toward the cylinder wall for capture. Therefore, the solid particles in the oversprayed dust can be fully captured and collected.

[0032] As a further embodiment of the present invention, the first rotating rod 4 and the second rotating rod 8 are connected by a first transmission mechanism, and the first rotating rod 4 will drive the second rotating rod 8 to rotate synchronously when it rotates. The first transmission mechanism includes a first sprocket 13 mounted on a first rotating rod 4 and a second sprocket 14 mounted on a second rotating rod 8, with the first sprocket 13 and the second sprocket 14 being driven by a chain 15.

[0033] In this embodiment, when the first rotating rod 4 rotates, it drives the first sprocket 13 to rotate. The first sprocket 13 and the second sprocket 14 are driven to rotate by the chain 15, which in turn drives the second rotating rod 8 to rotate. The rotation of the second rotating rod 8 drives the crucible 9 to rotate synchronously. Thus, the rotation of the crucible 9 makes the surface of the solid particles inside the crucible 9 receive a more uniform temperature airflow when heated.

[0034] As a further embodiment of the present invention, the bottom of the cyclone separator 2 is connected to a discharge cylinder 11 that communicates with the interior of the heating chamber 7. The discharge cylinder 11 extends into the interior of the heating chamber 7 and the discharge port is located above the crucible 9. A valve 12 is installed on the discharge cylinder 11 to control the opening and closing of the internal passage of the discharge cylinder 11.

[0035] In this embodiment, valve 12 is used to control the opening and closing of the internal passage of the discharge cylinder 11. After sufficient solid particles are collected inside the first rotating rod 4, valve 12 can be opened briefly to allow the solid particles inside the first rotating rod 4 to fall quickly into the crucible 9 through the discharge cylinder 11. The discharge cylinder 11 is made of heat-insulating material to reduce the heat conduction from the heating chamber 7 to the first rotating rod 4.

[0036] As a further embodiment of the present invention, a main shaft 16 is rotatably mounted on the frame 1. The main shaft 16 and the first rotating rod 4 are connected by a second transmission mechanism. When the main shaft 16 rotates, it will drive the first rotating rod 4 to rotate synchronously. A motor 17 is mounted on the frame 1. The output end of the motor 17 is connected to the main shaft 16 through a coupling to drive the main shaft 16 to rotate. The second transmission mechanism includes a bevel gear ring 18 mounted on the main shaft 16 and a bevel gear 19 mounted on the first rotating rod 4, with the bevel gear ring 18 meshing with the bevel gear 19.

[0037] In this embodiment, the motor 17 is electrically connected to an external power source via a wire. When the motor 17 is started, it drives the main shaft 16 to rotate. The rotation of the main shaft 16 drives the bevel gear ring 18 to rotate. The bevel gear ring 18 meshes with the bevel gear 19, which in turn drives the first rotating rod 4 to rotate.

[0038] As a further embodiment of the present invention, the air extraction mechanism includes a piston cylinder 20 mounted on a frame 1, a piston rod 21 movably inserted into the piston cylinder 20, a piston 22 movably engaged with the piston rod 21 inside the piston cylinder 20, an air intake pipe 25 communicating with the interior of the heating chamber 7 and an exhaust pipe 26 communicating with the interior of the incinerator 27 on the piston cylinder 20, and the piston rod 21 and the main shaft 16 are driven by a third transmission mechanism, and when the main shaft 16 rotates, it will drive the piston rod 21 to slide up and down inside the piston cylinder 20.

[0039] In this embodiment, when the main shaft 16 rotates, the piston rod 21 is driven to move up and down inside the piston cylinder 20 by a third transmission mechanism. When the main shaft 16 rotates, the piston rod 21 moves up and down inside the piston cylinder 20. When the piston rod 21 moves up and down inside the piston cylinder 20, it works with the suction pipe 25 and the exhaust pipe 26 to continuously draw the gas inside the heating chamber 7 into the incinerator 27 for combustion.

[0040] As a further embodiment of the present invention, the third transmission mechanism includes a turntable 24 disposed on the main shaft 16, and a swing arm 23 disposed between the turntable 24 and the piston rod 21, with the two ends of the swing arm 23 being hinged to the turntable 24 and the piston rod 21 respectively.

[0041] In this embodiment, when the spindle 16 rotates, it drives the turntable 24 to rotate. The rotation of the turntable 24 drives the swing arm 23 to swing. The swing arm 23 drives the piston rod 21 to move up and down, thereby driving the piston 22 to slide up and down inside the piston cylinder 20.

[0042] As a further embodiment of the present invention, a first one-way valve is installed on the intake pipe 25. The first one-way valve allows gas inside the heating chamber 7 to enter the piston cylinder 20 in one direction only through the second rotating rod 8. A second one-way valve is installed on the exhaust pipe 26. The second one-way valve allows gas inside the piston cylinder 20 to enter the incinerator 27 in one direction only through the exhaust pipe 26.

[0043] In this embodiment, the first one-way valve only allows the gas inside the heating chamber 7 to enter the piston cylinder 20 through the second rotating rod 8 in one direction, and the second one-way valve only allows the gas inside the piston cylinder 20 to enter the incinerator 27 through the exhaust pipe 26 in one direction. Therefore, when the piston rod 21 slides up and down inside the piston cylinder 20, it can work with the suction pipe 25 and the exhaust pipe 26 to continuously draw the gas inside the heating chamber 7 into the piston cylinder 20 in one direction, and then transport it to the incinerator 27 for combustion.

[0044] In use, the overspray dust formed during plasma spraying without material deposition enters the cyclone separator 2 tangentially through the air inlet pipe 3, forming a high-speed vortex. This causes large solid particles in the overspray dust to be separated by centrifugal force and fall against the cylinder wall of the cyclone separator 2, thus enabling rapid separation and collection of large solid waste particles in the overspray dust. Furthermore, a turbulence mechanism is installed inside the cyclone separator 2 to agitate the airflow by generating high-frequency micro-vibrations. For fine particles in the dust, centrifugal force alone is insufficient to separate them. The high-frequency micro-vibrations of the turbulence mechanism disrupt the originally stable streamlined motion trajectory of the fine particles, increasing the chance of collisions between the disturbed particles. This causes them to adhere and merge during the collisions, forming larger particles. These larger particles are then effectively thrown against the cylinder wall by centrifugal force and captured. Therefore, the solid particles in the overspray dust can be fully captured and collected. The separated solid particulate waste enters the crucible 9 inside the heating chamber 7. The electric heating wire 10 is spirally arranged around the outer wall of the crucible 9. The electric heating wire 10 is turned on to heat the crucible 9. During heating, nitrogen gas is continuously introduced into the heating chamber 7, causing the solid particulate matter inside the crucible 9 to decompose into most of the inorganic matter. The solid particulate matter is mainly hydroxyapatite, so the decomposition reaction of hydroxyapatite mainly occurs, producing inorganic matter such as tricalcium phosphate and tetracalcium phosphate. At the same time, the gases produced by decomposition are mainly water vapor and CO produced by incomplete combustion. The gases are then extracted by the gas extraction mechanism to the incinerator 27 for further incineration. After incineration, the gases are converted into clean gases before being discharged. For example, CO is converted into CO2 after incineration, so it will not cause pollution to the environment.

[0045] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
