Automatic weighing device for waste incineration activated carbon

Abstract

This utility model relates to the field of waste incineration technology and proposes an automatic weighing device for activated carbon in waste incineration. The device includes a housing, a drive assembly mounted on the top of two support plates, a feeding assembly mounted on the top of one support plate, a support assembly installed inside the limiting box, and a pushing assembly mounted on the bottom wall of the inner cavity of the housing. An actuating cylinder drives a positioning rod upwards, causing a wheel to contact a placement plate. As the positioning rod moves upwards, the wheel's contact position becomes increasingly biased towards the left end of the placement plate. The pushing assembly causes the placement plate to rotate on a fixed rod, tilting the plate. This tilting causes a baffle to move, facilitating the feeding of activated carbon through the outlet to the lower part of the device. This allows for precise control of the activated carbon input based on the weighing results, enabling more accurate adjustment of the activated carbon usage. This technical solution solves the problem of unstable activated carbon feeding in existing technologies.

[0002] In daily life, a large amount of waste is inevitably generated. If this waste is not effectively treated, it will greatly affect people's living environment and even threaten their health. Currently, incineration is one of the main methods of waste disposal. Waste-to-energy plants use activated carbon to filter the exhaust gases during operation.

[0003] Currently, there are no dedicated weighing and metering devices for the delivery of activated carbon, which leads to deviations in the quantity and weight of activated carbon each time it is input. This can result in incomplete purification of waste incineration plant exhaust gas, affecting the equipment's performance and impacting the surrounding environment. Utility Model Content

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-6 As shown in the figure, this embodiment proposes an automatic weighing device for activated carbon from waste incineration, including a housing 1, a support plate 2 fixedly connected inside the housing 1, a support plate 3 fixedly connected inside the housing 1 and below the support plate 2, a drive assembly 5 installed at the top of the support plate 3, and a feeding assembly 6 installed at the top of the support plate 2; a limiting box 7, a limiting box 7 fixedly connected to the bottom wall of the inner cavity of the housing 1, a support assembly 8 installed inside the limiting box 7, and a pushing assembly 9 installed on the bottom wall of the inner cavity of the housing 1 and inside the limiting box 7.

[0028] Furthermore, the support component 8 includes a fixed rod 81, which is fixedly connected inside the limiting box 7. An inclined plate 82 is fixedly connected to the middle of the fixed rod 81. The lower end of the inclined plate 82 is fixedly connected to the bottom wall of the inner cavity of the box 1. A placement plate 83 is rotatably connected to the fixed rod 81 and located in front of the inclined plate 82. A baffle 84 is fixedly connected to the right end of the placement plate 83. As the pushing component 9 works, the placement plate 83 rotates on the fixed rod 81, tilting the placement plate 83. As the placement plate 83 tilts, the baffle 84 moves, facilitating the placement of activated carbon through the outlet 12 to the lower part of the inclined plate 82. The baffle 84 can prevent activated carbon powder from entering the fixed rod 81, ensuring the service life of the placement plate 83 and ensuring the quantity of activated carbon input each time.

[0029] Furthermore, the driving component 9 includes a cylinder 91. The cylinder 91 is fixedly connected to the bottom wall of the inner cavity of the housing 1 and inside the limiting box 7. A positioning rod 92 is fixedly connected to the output end of the cylinder 91. A wheel 93 is rotatably connected to the positioning rod 92 near its front end. When the cylinder 91 is activated, it drives the positioning rod 92 to move upward. The positioning rod 92 drives the wheel 93 to contact the placement plate 83. As the positioning rod 92 moves upward, the contact position of the wheel 93 becomes more and more biased towards the left end of the placement plate 83, causing the placement plate 83 to tilt. Under the action of gravity, the activated carbon enters below and is then sprayed into the flue of the waste incinerator through a special device, or placed in the adsorption device of the flue gas purification system, so that the flue gas can fully contact the activated carbon to achieve the purpose of adsorption and purification.

[0030] Furthermore, a feeding hopper 4 is fixedly connected to the top wall of the inner cavity of the box 1 above the feeding assembly 6, and a discharging hopper 10 is fixedly connected to the bottom end of the support plate 1 2 below the feeding assembly 6. A weighing device 11 is fixedly connected to the bottom wall of the inner cavity of the box 1 to the left of the pushing assembly 9. A discharge port 12 is opened at the bottom end of the box 1 near the right end. Activated carbon is added through the feeding hopper 4 and then sent to the support assembly 8 through the discharging hopper 10.

[0031] In this embodiment, activated carbon is fed onto the placement plate 83 by the feeding component 6. The weighing end of the weighing device 11 contacts the bottom of the placement plate 83 to weigh the activated carbon. Once a suitable weight is reached, the component 9 is activated, and the cylinder 91 moves the positioning rod 92 upward. The positioning rod 92 moves the wheel 93 to contact the placement plate 83. As the positioning rod 92 moves upward, the contact position of the wheel 93 becomes increasingly biased towards the left end of the placement plate 83, causing the placement plate 83 to tilt. Under the action of gravity, the activated carbon enters the lower part of the plate and is then sprayed into the flue of the waste incinerator through specialized equipment, or placed in the adsorption device of the flue gas purification system, allowing the activated carbon to be absorbed by the flue gas. The gas comes into full contact with the activated carbon to achieve adsorption and purification. Support component 8 operates, and as component 9 operates, the placement plate 83 rotates on the fixed rod 81, tilting the placement plate 83. This tilting causes the baffle 84 to move, facilitating the delivery of activated carbon through the outlet 12 to the lower part of the plate, in conjunction with the inclined plate 82. The baffle 84 prevents activated carbon powder from entering the fixed rod 81, ensuring the service life of the placement plate 83 and guaranteeing the quantity and weight of activated carbon input each time. This prevents incomplete purification of waste incineration gas and effectively adsorbs sulfur dioxide (SO2) and nitrogen oxides (NOx) produced during waste incineration. x This will help reduce the pollution of the atmospheric environment by removing acidic gases such as hydrogen chloride (HCl) and highly toxic organic pollutants such as dioxins.

[0032] Example 2

[0033] like Figures 1-4 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a drive component 5 including a servo motor 51. The servo motor 51 is fixedly connected to the top of the support plate 2 3. A rotating shaft 52 is fixedly installed at the output end of the servo motor 51. A drive bevel gear 53 is fixedly connected to the front end of the rotating shaft 52. A rotating rod 54 is rotatably connected to the top wall of the inner cavity of the housing 1 through a bearing. The lower end of the rotating rod 54 passes through the support plate 1 2 and is rotatably connected to the top of the support plate 2 3. A driven bevel gear 55 is fixedly connected to the rotating rod 54 and located below the support plate 1 2. The drive bevel gear 53 and the driven bevel gear 55 are meshed. A drive gear 56 is fixedly connected to the rotating rod 54 and located above the support plate 1 2. When the servo motor 51 is started, it drives the rotating shaft 52 to rotate the drive bevel gear 53. The drive bevel gear 53 drives the driven bevel gear 55 to rotate the rotating rod 54. The rotating rod 54 drives the drive gear 56 to rotate. The servo motor 51 can precisely control the output torque to meet different load and motion requirements.

[0034] Furthermore, the feeding assembly 6 includes an annular guide rail 61. The annular guide rail 61 is fixedly connected to the top of the support plate 2. A rotating block 62 is sleeved on the annular guide rail 61. A secondary rack 66 is fixedly connected to the rotating block 62. The secondary rack 66 is meshed with the drive gear 56. A main rack 63 is fixedly connected inside the rotating block 62. A positioning post 64 is fixedly connected to the top of the support plate 2 and located inside the rotating block 62. An opening and closing plate 65 is rotatably connected to the positioning post 64. The teeth on the main rack 63 and the opening and closing plate 65 are meshed. The drive gear 56 drives the rotating block 62 to rotate under the limitation of the annular guide rail 61 through the secondary rack 66. The rotating block 62 drives the main rack 63 to rotate the opening and closing plate 65 on the positioning post 64. This facilitates the control of the amount of activated carbon entering the device based on the weighing result of the weighing device 11, thereby more accurately adjusting the amount of activated carbon used and preventing insufficient activated carbon.

[0035] In this embodiment, activated carbon is added through the feeding hopper 4. The drive assembly 5 is activated, and the servo motor 51 drives the rotating shaft 52 to rotate the active bevel gear 53. The active bevel gear 53 drives the driven bevel gear 55 to rotate the rotating rod 54. The rotating rod 54 drives the active gear 56 to rotate. The servo motor 51 can precisely control the output torque to meet different load and motion requirements. The feeding assembly 6 is activated, and the active gear 56 drives the rotating block 62 to rotate under the constraint of the annular guide rail 61 through the secondary rack 66. The rotating block 62 drives the main rack 63 to rotate the opening and closing plate 65 on the positioning column 64. This allows for control of the amount of activated carbon entering the device based on the weighing result of the weighing device 11, thereby more accurately adjusting the amount of activated carbon used and preventing insufficient activated carbon.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
