Description

Technical Field

[0001] The present invention relates to the technical field of hazardous waste treatment, and particularly to an industrial hazardous waste incineration rotary kiln facilitating continuous coke discharging. Technical Background

[0002] Industrial hazardous waste is evenly and continuously fed into a rotary kiln through a specific feeding device. Key parameters such as the fuel supply amount, air amount, and combustion angle of the burner are precisely controlled to ensure that the hazardous waste is fully burned in the kiln. The resulting high-temperature environment promotes the decomposition of organic components and the melting of inorganic components in the waste, ultimately forming coke slag. When the coke slag reaches the coke discharging device at the kiln tail, this device can continuously discharge the coke slag out of the kiln to achieve a continuous coke discharging process. For example, in the hazardous waste rotary kiln incineration on-line coke removal device with the patent number CN112361354A, a spiral coke scraping knife is provided, and the scraping knife rotates relative to the inner wall of the rotary kiln cylinder to scrape the coking substances at the outlet of the rotary kiln. Although the above patent content can achieve the function of scraping and discharging coke, there are still certain deficiencies in the process of coke block feeding: First of all, during the feeding process, due to the different sizes of coke blocks, some coke blocks with larger volumes are likely to cause blockage of the feeding channel. In addition, due to the volume differences of coke blocks, the cooling speeds of coke blocks of different sizes are different during the cooling process, resulting in an extended overall coke discharging and cooling time. Secondly, the discharging channel provided at the bottom of the rotary kiln is too short, resulting in a lack of sufficient buffer cooling time for the high-temperature coke blocks during the discharging process. This is likely to cause the high-temperature materials to directly contact the subsequent equipment and cause equipment damage, thereby affecting the continuous coke discharging effect of the rotary kiln. Summary of the Invention

[0003] The purpose of the present invention is, on the basis of adapting the inner wall of the rotary kiln to scraping and discharging coke, to not only extend the buffer cooling time for the discharged high-temperature coke blocks, reduce equipment damage caused by high temperature, but also reduce the problems of blockage and extended cooling time caused by volume differences of coke blocks through increasing the length of the discharging channel and dynamically crushing the coke blocks in the discharging state, so as to achieve an efficient continuous coke discharging effect.

[0004] The purpose of the present invention can be achieved by the following technical solutions: An industrial hazardous waste incineration rotary kiln facilitating continuous coke discharging, including a kiln body.

A scraping component is arranged at the top inside the discharging vertical cylinder I, and a feeding transverse cylinder is horizontally penetrated through both sides of the discharging vertical cylinder II and near the connection of the discharging vertical cylinder I. A limiting frame is provided at the bottom end of the first discharge vertical cylinder. Two groups of the material-passing horizontal cylinders are respectively fixedly installed on the inner wall of the rear end of the limiting frame through a machine base. A discharging and unloading mechanism is arranged inside the limiting frame, and a cooling frame is arranged at the bottom end of the discharging and unloading mechanism inside the limiting frame; Among them, the scraping component includes a scraping vertical piece fixedly installed on the inner side wall of the first discharge vertical cylinder, and the extended end of the top of the scraping vertical piece matches the conical discharge section inside the kiln body. A plurality of groups of scraping horizontal pieces are fixedly arranged at equal distances from top to bottom on one side surface of the scraping vertical piece corresponding to the inner wall of the conical discharge section of the kiln body, and one end of the scraping horizontal piece is an inclined section and is attached to the inner wall of the conical discharge section of the kiln body.

[0005] Furthermore, a limiting gear ring is fixedly sleeved on the outside of the first discharge vertical cylinder at the upper end of the material-passing horizontal cylinder. A first motor is arranged on the top surface of one of the material-passing horizontal cylinders on one side of the first discharge vertical cylinder, and a double-shaft gear is fixedly installed at the output end of the top of the first motor. A double-shaft gear is also rotatably arranged on the top surface of the other group of material-passing horizontal cylinders through a rotating shaft, and the limiting gear ring is engaged between the two double-shaft gears.

[0006] Furthermore, the discharging and unloading mechanism includes two groups of material-breaking tooth discs. The two groups of material-breaking tooth discs respectively penetrate through the inner walls of the two groups of material-passing horizontal cylinders and are close to the connection port end of the second discharge vertical cylinder. Pushing rods are fixedly installed at the ends of the two groups of material-breaking tooth discs far away from each other, and one end of the pushing rod extends outside the limiting frame and is fixedly installed with a driven gear.

[0007] Furthermore, a material-blocking disc is fixedly installed on the outside of the pushing rod adjacent to the material-breaking tooth disc. The material-blocking disc is adapted to the inner wall of the material-passing horizontal cylinder, and the outer diameter of the material-breaking tooth disc is 2 cm smaller than the outer diameter of the material-blocking disc. Two groups of blocking discs are fixedly installed at the center of the outside of the pushing rod.

[0008] Furthermore, the discharging and unloading mechanism further includes a double-shaft motor, and the double-shaft motor is arranged on the inner wall of the front end of the limiting frame. Threaded rotating rods with opposite thread directions are respectively fixedly installed at the output shafts on both sides of the double-shaft motor. Spiral sliding frames are threadedly sleeved at the middle sections of the outside of the two groups of threaded rotating rods, and sliders are hinged at the centers of the upper and lower ends of the spiral sliding frames.

[0009] Furthermore, an H-shaped abutting frame is sleeved on the outside of each group of spiral sliding frames, and clamping grooves are arranged at the front end openings of the upper and lower end faces of the H-shaped abutting frame. Each group of sliders is respectively slidably connected to the inner wall of the corresponding clamping groove. The H-shaped abutting frame is hinged through a hinge rod fixedly installed on the side wall of the limiting frame, and the end of the H-shaped abutting frame far away from the spiral sliding frame is sleeved on the outer wall of the pushing rod and is located between two adjacent groups of blocking discs.

[0010] Furthermore, one ends of the two spiral rods away from the biaxial motor extend to the outer wall of the limit frame and are fixedly installed with auxiliary rotating toothed rollers, and the auxiliary rotating toothed rollers are meshed with the driven gears on the same side. An eccentric runner is fixedly installed at the end of the spiral rod near the biaxial motor.

[0011] Furthermore, the shaft rods on both sides of the cooling frame are hinged to the card seats fixedly installed at the extended part of the bottom surface of the limit frame, and two sets of resisting rods are fixedly installed at the center of the front end of the top surface of the cooling frame. The top surfaces of the two sets of resisting rods are of a curved surface structure and correspond to the eccentric runner up and down.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses the first discharge vertical cylinder to drive the scraping blades and the scraping cross pieces to rotate. The scraping cross pieces scrape the coke lumps attached to the surface of the conical discharge section inside the kiln body. At the same time, the scraped coke lumps can fall into the first discharge vertical cylinder along the inclined section of the scraping cross piece, effectively avoiding the residue of coke lumps on the inner wall of the kiln body, improving the continuity of coke discharging, and at the same time avoiding the corrosion of the inner wall of the kiln body by the residual coke lumps, and prolonging the service life of the rotary kiln; 2. The present invention also uses the biaxial motor to drive the two spiral rods with opposite thread directions to rotate synchronously, so that the two spiral sliding frames drive the corresponding H-shaped resisting frames to reciprocate along one end of the hinge rod, and then push the pushing rod to reciprocate along the inner wall of the kiln body. The two material breaking toothed discs are inserted into the second discharge vertical cylinder at the same time and jointly perform extrusion and crushing treatment on the coke lumps accumulated inside the second discharge vertical cylinder. The material breaking toothed discs rotate, and are cut and clamped by using the distance between the two material breaking toothed discs and the inner wall of the second discharge vertical cylinder, so as to further break the large-volume coke lumps passing by. By setting the discharging and unloading mechanism, the coke lumps accumulated inside the second discharge vertical cylinder can be broken and evenly discharged and unloaded, forcing the coke lumps to uniformly fall into the cooling frame, avoiding the accumulation of coke lumps inside the second discharge vertical cylinder, and improving the cooling efficiency of the coke lumps; At the same time, the two spiral rods are used to drive the two eccentric runners to rotate, and intermittently press the two resisting rods, forcing the cooling frame to swing with the shaft rods on both sides as the center, increasing the heat dissipation area of the coke lumps by the reciprocating swing of the cooling frame, and reducing the adhesion between the coke lumps, further improving the cooling efficiency of the coke lumps.

[0016] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment 1: Please refer to Figures 1-7 As shown, an industrial hazardous waste incineration rotary kiln facilitating continuous coke discharging includes a kiln body 1. A first discharging vertical cylinder 2 is rotatably arranged at the tapered discharging section at the bottom end of the kiln body 1. A limit tooth ring 201 is fixedly sleeved outside the first discharging vertical cylinder 2 at the upper end of a material-passing horizontal cylinder 5. A first motor 202 is arranged on the top surface of the material-passing horizontal cylinder 5 on one side of the first discharging vertical cylinder 2, and a double-shaft gear 203 is fixedly installed at the top output end of the first motor 202. The double-shaft gear 203 meshes with the limit tooth ring 201; And the bottom end of the first discharging vertical cylinder 2 is rotatably connected to a second discharging vertical cylinder 3. By adding the second discharging vertical cylinder 3 at the bottom of the first discharging vertical cylinder 2, the purpose is that a longer discharging channel allows high-temperature coke blocks to have more sufficient cooling time before being discharged, avoiding damage caused by direct contact between high-temperature materials and subsequent equipment; Inside the first discharge vertical cylinder 2 at the top, there is a scraping component 4. Among them, the scraping component 4 includes a scraping vertical piece 41 fixedly installed on the inner side wall of the first discharge vertical cylinder 2, and the extended end at the top of the scraping vertical piece 41 matches the conical discharge section inside the kiln body 1. On one side of the scraping vertical piece 41 and at equal distances from top to bottom, several groups of scraping horizontal pieces 42 are fixedly installed corresponding to the inner wall of the conical discharge section of the kiln body 1; One end of the scraping horizontal piece 42 is an inclined section and is attached to the inner wall of the conical discharge section of the kiln body 1. And on both sides of the second discharge vertical cylinder 3 and near the connection with the first discharge vertical cylinder 2, there are horizontally penetrating through-material horizontal cylinders 5. At the bottom of the first discharge vertical cylinder 2, there is a limit frame 6. The two through-material horizontal cylinders 5 are respectively fixedly installed on the inner wall at the rear end of the limit frame 6 through a machine base. Inside the limit frame 6, there is a discharging and unloading mechanism 7, and at the bottom of the discharging and unloading mechanism 7 inside the limit frame 6, there is a cooling frame 8; The burned coke lumps are discharged outwards through the conical discharge port at the bottom of the kiln body 1. The coke lumps pass through the inside of the first discharge vertical cylinder 2 and the second discharge vertical cylinder 3 in sequence. Then, start the first motor 202 to drive the double-axis gear 203 to rotate. Since the double-axis gear 203 meshes with the limit tooth ring 201, it forces the first discharge vertical cylinder 2 to rotate at the conical discharge section at the bottom of the kiln body 1, and drives the scraping vertical piece 41 to make a circular motion along the inside of the kiln body 1. And several groups of scraping horizontal pieces 42 scrape the coke lumps attached to the inner wall of the conical discharge section of the kiln body 1, preventing the coke lumps from sticking to the inner wall of the conical discharge section of the kiln body 1, which may cause the coke lumps to be difficult to discharge and cause blockage. By extending the feeding tube channel of the coke lumps, it is convenient for Under the action of the scraping component 4, the coke lumps are scraped off from the inner wall of the conical discharge section of the kiln body 1 and fall into the first discharge vertical cylinder 2. The coke lumps fall from the bottom of the first discharge vertical cylinder 2 into the second discharge vertical cylinder 3 in sequence, and the discharging and unloading mechanism 7 performs discharging and unloading treatment on the coke lumps inside the second discharge vertical cylinder 3, forcing the coke lumps to evenly fall into the cooling frame 8 for cooling treatment, so as to facilitate the subsequent transfer treatment of the coke lumps; That is, by setting the scraping component 4, the coke lumps attached to the inner wall of the conical discharge section of the kiln body 1 can be scraped off, avoiding the blockage of the coke lumps at the conical discharge section of the kiln body 1 and improving the discharge efficiency of the coke lumps.

[0018] Embodiment 2: Please refer to Figure 3 - Figure 5 As shown, the discharging and unloading mechanism 7 includes two material-breaking tooth discs 71. The two material-breaking tooth discs 71 are respectively penetrated through the inner walls of the two through-material horizontal cylinders 5 and near the connection port of the second discharge vertical cylinder 3. At the ends of the two material-breaking tooth discs 71 away from each other, there are push rods 72 fixedly installed, and one end of the push rod 72 extends outside the limit frame 6 and is fixedly installed with a driven gear 73; A material pushing rod 72 is externally fixed with a material blocking disc 74 adjacent to the material breaking tooth disc 71. The material blocking disc 74 is adapted to the inner wall of the material passing horizontal cylinder 5, and the outer diameter of the material breaking tooth disc 71 is 2 cm less than the outer diameter of the material blocking disc 74. Two sets of blocking discs 75 are fixedly installed at the center of the outer part of the material pushing rod 72. The discharging and unloading mechanism 7 further includes a double-shaft motor 76, and the double-shaft motor 76 is arranged at the inner wall of the front end of the limiting frame 6. Screw rotating rods 77 with opposite thread directions are fixedly installed on the output shafts on both sides of the double-shaft motor 76. A spiral sliding frame 78 is threadedly sleeved on the middle section of the outer parts of the two sets of screw rotating rods 77, and sliders 79 are hinged at the centers of the upper and lower ends of the spiral sliding frame 78; Each set of spiral sliding frames 78 is sleeved with an H-shaped abutting frame 710, and clamping grooves are arranged at the front end openings of the upper and lower end faces of the H-shaped abutting frame 710. Each set of sliders 79 is respectively slidably connected to the inner walls of the corresponding clamping grooves, and the H-shaped abutting frame 710 is hinged through a hinge rod fixedly installed on the side wall of the limiting frame 6; And one end of the H-shaped abutting frame 710 away from the spiral sliding frame 78 is sleeved on the outer wall of the material pushing rod 72 and is located between two adjacent sets of blocking discs 75. The ends of the two sets of screw rotating rods 77 away from the double-shaft motor 76 extend to the outer wall of the limiting frame 6 and are fixedly installed with auxiliary rotating gear rollers 711, and the auxiliary rotating gear rollers 711 are meshed with the driven gears 73 on the same side; When using the discharging vertical cylinder II 3 to convey coke lumps, the double-shaft motor 76 is started to drive the two sets of screw rotating rods 77 with opposite thread directions to rotate synchronously, forcing the spiral sliding frame 78 to perform a linear reciprocating motion on the outer parts of the screw rotating rods 77. The spiral sliding frame 78 drives the H-shaped abutting frame 710 to swing around the hinge rod through the sliders 79 hinged at the upper and lower ends. The H-shaped abutting frame 710 then pushes the blocking discs 75 sleeved on the outer wall of the material pushing rod 72, forcing the material pushing rod 72 to drive the material breaking tooth disc 71 to reciprocate inside the material passing horizontal cylinder 5. When the two sets of material breaking tooth discs 71 are inserted into the discharging vertical cylinder II 3 at the same time, they jointly perform extrusion and crushing treatment on the coke lumps accumulated inside the discharging vertical cylinder II 3; At the same time, along with the rotation of the two sets of screw rotating rods 77, the auxiliary rotating gear rollers 711 at their ends are driven to rotate, and the auxiliary rotating gear rollers 711 are meshed with the adjacent driven gears 73, forcing the driven gears 73, the material pushing rod 72 and the material breaking tooth disc 71 to rotate. The two sets of material breaking tooth discs 71 cut and clamp by using the distance from the inner wall of the discharging vertical cylinder II 3, so as to further break the large-volume coke lumps passing by; and when the two sets of material breaking tooth discs 71 return to their positions, the blocking of the broken coke lumps is lost and the material is discharged; It should be noted that when the material breaking tooth disc 71 is inserted into the discharging vertical cylinder II 3, the material blocking disc 74 moves to the opening of the material passing horizontal cylinder 5 and blocks the inside of the material passing horizontal cylinder 5 to prevent coke lumps from entering the inside of the material passing horizontal cylinder 5. By arranging the discharging and unloading mechanism 7, the coke lumps accumulated inside the discharging vertical cylinder II 3 can be broken and evenly discharged, forcing the coke lumps to evenly fall into the cooling frame 8, preventing the coke lumps from accumulating inside the discharging vertical cylinder II 3, and improving the cooling efficiency of the coke lumps.

[0019] Embodiment 3: Please refer to Figure 3 and Figure 6 - Figure 7 As shown in FIGS. An eccentric runner 712 is fixedly installed near the end of the double-shaft motor 76 on the outside of the spiral rod 77; both side shafts of the cooling frame 8 are hinged to the card seats fixedly installed at the extended part of the bottom surface of the limit frame 6, and two sets of abutting rods 9 are fixedly installed at the center of the front end of the top surface of the cooling frame 8. The top surfaces of the two sets of abutting rods 9 are of a curved surface structure and correspond to the eccentric runner 712 up and down; The crushed coke block particles fall on the surface of the cooling frame 8 for cooling and heat dissipation. When the two spiral rods 77 rotate, the two eccentric runners 712 rotate accordingly and intermittently press against the two abutting rods 9, forcing the cooling frame 8 to swing with the two side shafts as the center of the circle. The reciprocating swing of the cooling frame 8 increases the heat dissipation area of the coke block particles and reduces the adhesion between the coke block particles, further improving the cooling efficiency of the coke block particles;

[0020] Working principle: First, the incinerated coke blocks are discharged outwards through the conical discharge port at the bottom of the kiln body 1. The coke blocks pass through the inside of the first discharge vertical cylinder 2 and the second discharge vertical cylinder 3 in sequence, and then start the first motor 202 to drive the double-shaft gear 203 to rotate. Since the double-shaft gear 203 meshes with the limit tooth ring 201, the first discharge vertical cylinder 2 rotates at the conical discharge section at the bottom end of the kiln body 1, and drives the scraping vertical piece 41 to move in a circular motion along the inside of the kiln body 1, and several groups of scraping horizontal pieces 42 scrape the coke blocks attached to the inner wall of the conical discharge section of the kiln body 1 to prevent the coke blocks from sticking to the inner wall of the conical discharge section of the kiln body 1; Next, under the action of the scraping component 4, the coke blocks are scraped off from the inner wall of the conical discharge section of the kiln body 1 and fall into the inside of the first discharge vertical cylinder 2. The coke blocks fall from the bottom end of the first discharge vertical cylinder 2 into the inside of the second discharge vertical cylinder 3 in sequence. Start the double-shaft motor 76 to drive the two spiral rods 77 with opposite thread directions to rotate synchronously, forcing the spiral sliding frame 78 to move in a straight reciprocating motion on the outside of the spiral rod 77, and the spiral sliding frame 78 drives the H-shaped abutting frame 710 to swing with the hinge rod as the center of the circle through the sliders 79 hinged at the upper and lower ends. The H-shaped abutting frame 710 pushes the blocking disc 75 sleeved on the outside of the pushing rod 72, forcing the pushing rod 72 to drive the crushing tooth disc 71 to reciprocate inside the through-feed horizontal cylinder 5. When the two crushing tooth discs 71 are inserted into the inside of the second discharge vertical cylinder 3 at the same time, they jointly perform extrusion and crushing treatment on the coke blocks accumulated inside the second discharge vertical cylinder 3; Meanwhile, as the two sets of spiral rods 77 rotate, the auxiliary rotating toothed rollers 711 at their ends are driven to rotate. The auxiliary rotating toothed rollers 711 are engaged with the adjacent driven gears 73, forcing the driven gears 73, the material pushing rods 72 and the material breaking toothed discs 71 to rotate. The two sets of material breaking toothed discs 71 are used to cut and clamp according to the distance from the inner wall of the second discharge vertical cylinder 3, so as to further break the large-volume coke lumps passing by. The broken coke lump particles fall on the surface of the cooling frame 8 for cooling and heat dissipation. When the two sets of spiral rods 77 rotate, the two sets of eccentric rotating wheels 712 rotate accordingly and intermittently press against the two sets of pressing rods 9, forcing the cooling frame 8 to swing around the shaft rods on both sides. By the reciprocating swing of the cooling frame 8, the heat dissipation area of the coke lump particles is increased, and the adhesion between the coke lump particles is reduced.
