Description

Technical Field

[0001] This utility model relates to the field of hazardous waste technology, specifically to a high-temperature melting device for hazardous waste. Background Technology

[0002] Hazardous waste refers to solid waste listed in the National Hazardous Waste Inventory or identified as having hazardous characteristics according to national hazardous waste identification standards and methods. Waste disposal involves treating waste and then recycling it appropriately. Hazardous waste, due to its hazardous nature, requires high-temperature melting treatment before recycling to achieve its harmlessness and resource recovery. This process includes steps such as crushing, drying, sintering, melting, and water quenching. Crushing refers to grinding larger volumes of waste.

[0003] A search revealed that Chinese patent application number 202221864293.4 discloses a high-temperature melting treatment device for hazardous waste, comprising a crushing device (1), a homogenization chamber (2), a drying device (3), a sintering machine (4), a high-temperature melting furnace (5), and a water quenching tank (6) connected in sequence. The crushing device (1) includes a shell (7), and a drive gear (8) is rotatably connected to and meshes with the output end of a motor on the inner side of the shell (7). A main shaft (9) is provided on the drive gear (8), and a toothed roller (10) is slidably connected on the main shaft (9). A return spring (11) is provided between the end of the toothed roller (10) and the drive gear (8). Drive rods (12) are slidably connected to the toothed roller (10) on both sides of the drive gear (8). The toothed roller of this invention can crush hazardous waste from two directions simultaneously, effectively improving the crushing effect and further enhancing the treatment effect.

[0004] Although the aforementioned patent can crush hazardous waste from two directions simultaneously, effectively improving the crushing effect and further enhancing the treatment effect, in actual use, unidirectional crushing by toothed rollers is prone to material jamming. Crushing waste by only a single toothed roller results in uneven crushing effect, and large pieces of waste can easily cause the toothed rollers to jam, reducing waste treatment efficiency and causing inconvenience to users.

[0005] Therefore, it is necessary to modify it by setting two symmetrical crushing rollers to crush the waste in both directions. At the same time, the waste being processed is squeezed and rolled during crushing to avoid jamming of the crushing rollers, improve the crushing effect, make the crushing uniform, improve the waste treatment efficiency, and make it convenient for users. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a high-temperature melting device for hazardous waste. This device features two symmetrical crushing rollers that crush waste bidirectionally. During crushing, the waste is squeezed and tumbled to prevent jamming, thus improving the crushing effect, ensuring uniform crushing, increasing waste treatment efficiency, and facilitating user operation. It solves the problems of easy jamming during unidirectional crushing with toothed rollers, uneven crushing effect due to using only a single toothed roller, and large pieces of waste easily causing jamming, reducing waste treatment efficiency and causing inconvenience to users.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature melting device for hazardous waste, comprising a crushing box, a screw conveyor connected to the lower right side of the crushing box, the output end of the screw conveyor connected to a melting mechanism, a circular groove on the back of the crushing box, a crushing drum rotatably connected inside the circular groove, crushing rollers located inside the crushing drum on both the left and right sides of the upper part of the crushing box, a plurality of evenly distributed discharge holes on the surface of the crushing drum, a closed rear cover inside the crushing drum, and first horizontal plates fixedly connected to the upper and lower sides of the back of the crushing box, the back of the closed rear cover... A second horizontal plate is fixedly connected to both the top and bottom sides. A vertical plate is fixedly connected to the rear ends of the first and second horizontal plates. A reduction motor is fixedly connected to the right side of the front of the vertical plate. A first gear is fixedly connected to the output end of the reduction motor. A second gear meshes with the left side of the surface of the first gear. A transmission rod is fixedly connected to the front of both the first and second gears. The front end of the transmission rod extends into the interior of the crushing box and is fixedly connected to the back of the crushing roller. An internal gear ring is fixedly connected to the rear end of the crushing roller. The right side of the surface of the first gear meshes with the inner wall of the internal gear ring. A feed hopper located between the crushing roller and the crushing drum is connected to the top of the front of the crushing box.

[0008] In a preferred embodiment of this invention, a first bearing is fixedly connected to the rear of the surface of the crushing drum, the outer surface of the first bearing is fixedly connected to the inner wall of the circular groove, and a second bearing is fixedly connected to the rear of the inner surface of the crushing drum, the inner surface of the second bearing is fixedly connected to the outer surface of the closed rear cover.

[0009] As a preferred embodiment of this utility model, the inner wall of the crushing drum is fixedly connected with a number of crushing racks that cooperate with the crushing drum, and the crushing racks are staggered with the discharge hole.

[0010] In a preferred embodiment of this invention, a sliding ring is fixedly connected to the front of the crushing drum surface, and a sliding groove is provided on the upper part of the inner wall of the crushing box to cooperate with the sliding ring. The surface of the sliding ring is slidably connected to the inner wall of the sliding groove.

[0011] As a preferred embodiment of this utility model, brush plates are fixedly connected to the lower left and right sides of the inner wall of the crushing box, and the brush ends of the brush plates are in contact with the surface of the crushing drum.

[0012] As a preferred embodiment of this utility model, a cleaning chamber door is hinged to the lower front of the crushing box, and sealing strips are fixedly connected around the cleaning chamber door, with the surface of the sealing strips adhering to the surface of the crushing box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a feeding hopper to add the waste material to be processed into the crushing box. The starting of the reduction motor drives the first gear to rotate counterclockwise. The rotation of the first gear drives the second gear and the internal gear ring to rotate, thereby simultaneously rotating the two crushing rollers and the crushing drum. The two crushing rollers rotate inwards simultaneously, crushing the waste material. The crushed waste falls to the bottom of the inner wall of the crushing drum. Larger pieces of waste continue to contact the crushing rollers for further crushing, until they are crushed to a standard size that can fall through the discharge port. The crushed waste is then conveyed by a screw conveyor to a melting mechanism for melting. The melting mechanism includes a homogenization chamber, a drying device, a sintering machine, a high-temperature melting furnace, and a water quenching tank. The working principles and connection methods of these components are well-known to those skilled in the art and will not be elaborated here. This design achieves bidirectional crushing of waste by two symmetrical crushing rollers. Simultaneously, the waste is squeezed and tumbled during crushing to prevent jamming of the crushing rollers, improving the crushing effect, ensuring uniform crushing, increasing waste processing efficiency, and facilitating user operation.

[0015] 2. By setting a first bearing and a second bearing, when the reduction motor drives the first gear to rotate, and the first gear drives the internal gear ring to rotate, the crushing drum rotates accordingly. The first bearing rotates on the outer surface of the crushing drum, and the second bearing rotates on the inner surface of the crushing drum. This effectively reduces the friction of the crushing drum during operation, making it more smooth and stable during rotation and improving the stability of the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a high-temperature melting device for hazardous waste, including a crushing box 1. A screw conveyor 2 is connected to the lower right side of the crushing box 1, and a melting mechanism 3 is connected to the output end of the screw conveyor 2. A circular groove is opened on the back of the crushing box 1, and a crushing roller 4 is rotatably connected inside the circular groove. The front of the crushing roller 4 is in contact with the front side of the inner wall of the crushing box 1. Crushing rollers 5 are arranged on the left and right sides of the upper part of the crushing box 1, located inside the crushing roller 4, and the inner sides of the two crushing rollers 5 are not meshed, leaving a gap. A number of evenly distributed discharge holes 6 are opened on the surface of the crushing roller 4. A closed rear cover 7 is provided inside the crushing roller 4. A first horizontal plate 8 is fixedly connected to the upper and lower sides of the back of the crushing box 1, and a second horizontal plate 9 is fixedly connected to the upper and lower sides of the back of the closed rear cover 7. A vertical plate 10 is fixedly connected to the rear end of the second horizontal plate 9. A reduction motor 11 is fixedly connected to the right side of the front of the vertical plate 10. A first gear 12 is fixedly connected to the output end of the reduction motor 11. A second gear 13 meshes with the left side of the surface of the first gear 12. A transmission rod is fixedly connected to the front of both the first gear 12 and the second gear 13. The front end of the transmission rod extends into the interior of the crushing box 1 and is fixedly connected to the back of the crushing roller 5. An internal gear ring 14 is fixedly connected to the rear end of the crushing roller 4. The right side of the surface of the first gear 12 meshes with the inner wall of the internal gear ring 14. The diameter of the second gear 13 is slightly smaller than the diameter of the first gear 12. When the first gear 12 drives the second gear 13 to rotate, its left side will not contact the internal gear ring 14. A feed hopper located between the crushing roller 4 and the crushing roller 5 is connected to the upper front of the crushing box 1.

[0023] refer to Figure 2 A first bearing 15 is fixedly connected to the rear of the surface of the crushing drum 4. The outer surface of the first bearing 15 is fixedly connected to the inner wall of the circular groove. A second bearing 16 is fixedly connected to the rear of the inner surface of the crushing drum 4. The inner surface of the second bearing 16 is fixedly connected to the outer surface of the closed rear cover 7.

[0024] As a technical optimization of this utility model, by setting a first bearing 15 and a second bearing 16, when the reduction motor 11 drives the first gear 12 to rotate, and the first gear 12 drives the internal gear ring 14 to rotate, the crushing drum 4 rotates accordingly. The first bearing 15 rotates on the outer surface of the crushing drum 4, and the second bearing 16 rotates on the inner surface of the crushing drum 4, which effectively reduces the friction of the crushing drum 4 during operation, making it more smooth and stable when rotating, and improving the stability of the device.

[0025] refer to Figure 3 The inner wall of the crushing drum 4 is fixedly connected with a number of crushing racks 17 that cooperate with the crushing roller 3. The height of the crushing racks 17 is less than the distance from the left and right sides of the inner wall of the crushing drum 4 to the surface of the crushing roller 5. The crushing racks 17 and the discharge hole 6 are staggered.

[0026] As a technical optimization of this utility model, by setting the crushing rack 17, when the crushing drum 4 rotates, the crushing rack 17 rotates around the crushing roller 5, and moves the waste around the crushing roller 5 so that it can get closer to the crushing roller 5, thereby improving the crushing effect.

[0027] refer to Figure 2 A sliding ring 18 is fixedly connected to the front of the surface of the crushing drum 4. A groove 19 is provided on the upper part of the inner wall of the crushing box 1 to cooperate with the sliding ring 18. The surface of the sliding ring 18 is slidably connected to the inner wall of the groove 19.

[0028] As a technical optimization of this utility model, by setting the sliding ring 18 and the sliding groove 19 to work together, when the crushing drum 4 rotates on the surface of the crushing drum 5, it drives the sliding ring 18 to rotate inside the sliding groove 19, which plays a supporting and reinforcing role for the crushing drum 4, making it more stable when rotating, and at the same time preventing the front end of the crushing drum 4 from tilting downwards, which would affect normal use.

[0029] refer to Figure 3 Brush plates 20 are fixedly connected to the lower left and right sides of the inner wall of the crushing box 1, and the brush ends of the brush plates 20 are in contact with the surface of the crushing drum 4.

[0030] As a technical optimization of this utility model, by setting up a brush plate 20, when the crushing drum 4 rolls, the brush end of the brush plate 20 rubs against its surface, and the discharge hole 6 can be cleaned by the brush plate 20, so as to avoid the discharge hole 6 being blocked and affecting the normal use of the device.

[0031] refer to Figure 1 A cleaning chamber door 21 is hinged to the lower front of the crushing box 1. Sealing strips 22 are fixedly connected around the cleaning chamber door 21, and the surface of the sealing strips 22 is in contact with the surface of the crushing box 1.

[0032] As a technical optimization of this utility model, by setting a cleaning chamber door 21, the cleaning chamber door 21 can be opened after the device is used to clean the waste remaining inside the device, so as to avoid contamination and corrosion of the device. By setting a sealing strip 22, the gap between the cleaning chamber door 21 and the crushing box 1 is sealed, so as to prevent waste leakage during use.

[0033] The working principle and usage process of this utility model are as follows: Waste material to be processed is added into the crushing box 1 through the feed hopper. The reduction motor 11 is started, driving the first gear 12 to rotate counterclockwise. When the first gear 12 rotates, it drives the second gear 13 and the internal gear ring 14 to rotate, thereby simultaneously rotating the two crushing rollers 5 and the crushing drum 4. The two crushing rollers 5 rotate inwards simultaneously, crushing the waste material. The crushed waste falls below the inner wall of the crushing drum 4. Material that meets the standard falls into the lower part of the crushing box 1 through the discharge port. Larger pieces of waste are continued to contact the crushing rollers 5 due to the movement of the crushing drum 4. The material is crushed until it reaches a standard size that can fall through the discharge port. After crushing, the waste is conveyed to the melting mechanism 3 by a screw conveyor. The melting mechanism 3 is equipped with a homogenization chamber, a drying device, a sintering machine, a high-temperature melting furnace, and a water quenching tank. Its working principle and connection method are well known to those skilled in the art and will not be described in detail here. This achieves the effect of crushing the waste in both directions by setting two symmetrical crushing rollers 5. At the same time, the waste is squeezed and rolled during crushing to avoid jamming of the crushing rollers 5, improve the crushing effect, make it uniform, improve the waste treatment efficiency, and facilitate the use of the user.
