Description

Technical Field

[0001] This utility model relates to waste incineration equipment, specifically to an automatic activated carbon dispensing device for waste incineration flue gas ducts. Background Technology

[0002] Waste incineration plants are facilities that treat municipal solid waste through high-temperature combustion. Their core purpose is to reduce and degrade waste, that is, to reduce the volume and weight of waste while destroying harmful substances and recovering energy in the process. Activated carbon is often used to adsorb and remove highly toxic pollutants from flue gas that are difficult to treat by other methods.

[0003] In order to fully adsorb pollutants, multiple powder spray guns that spray activated carbon powder into the flue are often installed circumferentially on the side wall of the flue. Above the powder spray guns is a storage chamber that provides activated carbon powder to the powder spray guns. Since the storage chamber has a limited volume, it is necessary to replenish the activated carbon powder to the storage chamber frequently. The traditional method is to replenish it manually, which is time-consuming and labor-intensive.

[0004] To address the above solution, a pneumatically conveyed replenishment pipe is installed between the activated carbon powder source and each powder spray gun to achieve automatic replenishment. However, this replenishment method results in complex pipelines around the flue and a bulky structure. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic activated carbon dispensing device for waste incineration flue gas pipelines with high dispensing efficiency and simplified pipeline structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a flue, with multiple powder spray guns arranged circumferentially to spray activated carbon powder into the flue. Above each powder spray gun is a storage chamber for storing activated carbon powder. It also includes a transfer chamber and a feeding pipe. The feeding pipe is annular and surrounds the outside of the flue. The feeding pipe is located above and connected to each storage chamber. The transfer chamber has a powder inlet pipe connected to an activated carbon powder source. Below the transfer chamber is a lifting support that elevates the transfer chamber above the feeding pipe. A portion of the transfer chamber serves as a supplementary section extending above the feeding pipe. Between the supplementary section and the feeding pipe is a supplementary pipe and a supplementary mechanism for conveying activated carbon powder from the supplementary section to the feeding pipe. The feeding pipe has a rectangular vertical cross-section. Inside the feeding pipe is a feeding trolley that travels along the feeding pipe and a driving mechanism that moves the feeding trolley. The feeding trolley has a feeding chamber for receiving activated carbon powder conveyed by the supplementary mechanism. Below the feeding chamber is a feeding mechanism that, when opposite to a storage chamber, puts activated carbon powder into the storage chamber.

[0007] By adopting the above technical solution, the activated carbon powder source is pneumatically transported to the transfer chamber through the powder inlet pipe. Then, the replenishment mechanism conveys the replenished activated carbon powder to the delivery pipe. Next, the delivery trolley receives the activated carbon powder from the replenishment mechanism in its delivery chamber. The delivery trolley then travels to a position opposite the storage chamber, and finally, the delivery mechanism delivers the activated carbon powder into the storage chamber. The above structure has the following advantages: ① Automatic delivery replaces manual delivery, greatly improving delivery efficiency and convenience; ② The transfer chamber serves as the transfer point, with activated carbon powder being uniformly delivered there first, and then delivered one by one by the delivery trolley. Compared to the traditional method of setting up independent activated carbon powder replenishment structures for each storage chamber, this greatly simplifies the pipeline structure; ③ The sealed delivery system formed by the transfer chamber, replenishment pipe, delivery pipe, and storage chamber, isolated from the outside environment, is conducive to long-term storage of activated carbon powder, thereby ensuring the pollutant adsorption effect of the activated carbon powder; ④ The independently supported transfer chamber greatly reduces the load on the flue and extends the service life of the flue.

[0008] The present invention is further configured such that: the traveling mechanism includes a traveling gear, a traveling rack, a traveling motor, and multiple guide wheels; the delivery trolley is arc-shaped and slides in cooperation with the internal structure of the delivery pipe; the inner wall of the delivery pipe near the flue serves as the traveling side wall, and the inner wall away from the flue serves as the guide side wall; the traveling motor is fixed to the delivery trolley and drives the horizontally arranged traveling gear to rotate; the traveling side wall is provided with a gear guide groove with the same thickness as the traveling gear; the traveling rack is arranged circumferentially in the gear guide groove and meshes with the traveling gear; the guide wheels are horizontally arranged on the delivery trolley; and the guide side wall is provided with a guide wheel groove with the same thickness as the guide wheel and rolls in cooperation with the guide wheel.

[0009] By adopting the above technical solution, the driving motor drives the driving gear to rotate, and then the driving rack meshes with the driving gear to drive the delivery trolley along the delivery pipeline. At the same time, with the help of multiple guide wheels, the driving gear and driving rack are stably meshed while ensuring the smooth movement of the delivery trolley.

[0010] The present invention is further configured such that: the dispensing mechanism includes a dispensing baffle, a dispensing track, and a dispensing motor; the dispensing track is disposed inside the dispensing trolley and connected to the side of the dispensing chamber; the dispensing baffle slides along the dispensing track; when the dispensing baffle slides, it has a supplementary position that blocks the lower end of the dispensing chamber and a dispensing position that is offset from the lower end of the dispensing chamber; a dispensing rack is disposed above the dispensing baffle along the sliding direction; and the dispensing motor is fixed to the dispensing trolley and drives a dispensing gear that meshes with the dispensing rack.

[0011] By adopting the above technical solution, the dispensing motor drives the dispensing gear to rotate, and then the dispensing rack meshing with the dispensing gear drives the dispensing baffle to slide back and forth, thereby realizing the free switching of the dispensing chamber between the replenishment state and the dispensing state.

[0012] The present invention is further configured to include a cleaning cylinder, which is fixed to the delivery pipe and corresponds one-to-one with the storage chamber. A cleaning pusher plate is driven below the cleaning cylinder to extend into the delivery chamber and completely push the activated carbon powder in the delivery chamber into the storage chamber.

[0013] By adopting the above technical solution, a cleaning cylinder is added to drive the cleaning pusher plate to extend into the feeding chamber and completely push the activated carbon powder in the feeding chamber into the storage bin, so as to avoid the activated carbon powder remaining in the feeding chamber and ensure that a sufficient amount of activated carbon powder is fed each time.

[0014] The present invention is further configured such that: a guide ramp is provided at the bottom of the transfer chamber, the height of the guide ramp gradually decreases from the powder inlet pipe to the replenishment section, and a vibrator is provided on the outer side of the transfer chamber.

[0015] By adopting the above technical solution, the guide ramp, in conjunction with the vibrator, gradually moves the activated carbon powder transported to the transfer chamber closer to the replenishment section, ensuring that the replenishment section has sufficient activated carbon powder. This guarantees that enough activated carbon powder is replenished to the delivery chamber each time, while also effectively preventing phenomena such as activated carbon powder blockage, bridging, and wall adhesion.

[0016] The present invention is further configured such that the replenishment mechanism is a star-shaped unloader located at the lower end of the replenishment pipe.

[0017] By adopting the above technical solution, the star-shaped unloader is preferred as the replenishment mechanism, which can efficiently replenish an equal amount of activated carbon powder and automatically cut off the replenishment pipeline when the conveying stops.

[0021] like Figure 1 — Figure 3As shown in the figure, this utility model discloses an automatic activated carbon dispensing device for a waste incineration flue gas duct. The attached figure only shows a partial flue duct 1 and a partial lifting support 32. It includes a flue duct 1, with multiple powder spray guns 2 arranged circumferentially to spray activated carbon powder into the flue duct 1. Above each powder spray gun 2 is a storage bin 21 for storing activated carbon powder. The storage bin 21 is usually equipped with a conveying mechanism to deliver activated carbon powder to the powder spray gun 2. It also includes a transfer bin 3 and a dispensing pipe 4. The dispensing pipe 4 is annular and surrounds the outside of the flue duct 1. The dispensing pipe 4 is located above each storage bin 21 and is connected to each storage bin 21. The transfer bin 3 is equipped with a powder inlet pipe 31 connected to the activated carbon powder source. Below the transfer bin 3 is a lifting support 32 that raises the transfer bin 3 above the dispensing pipe 4. The transfer bin 3 partially serves as a supplementary part 33 extending above the dispensing pipe 4. The supplementary part 33 and A replenishment pipe 34 and a replenishment mechanism for conveying activated carbon powder from the replenishment unit 33 to the replenishment pipe 4 are provided between the replenishment pipes 4. The vertical cross-section of the replenishment pipe 4 is rectangular. A replenishment trolley 5 that travels along the replenishment pipe 4 and a driving mechanism for driving the replenishment trolley 5 are provided inside the replenishment pipe 4. The replenishment trolley 5 is provided with a replenishment chamber 51 for receiving activated carbon powder conveyed by the replenishment mechanism. A replenishment mechanism for putting activated carbon powder into the storage chamber 21 when it is opposite to the storage chamber 21 is provided below the replenishment chamber 51. The activated carbon powder source is pneumatically transmitted to the transfer chamber 3 through the powder inlet pipe 31. Then, the replenishment mechanism conveys the activated carbon powder from the replenishment unit 33 to the replenishment pipe 4. Then, the replenishment chamber 51 of the replenishment trolley 5 receives the activated carbon powder conveyed by the replenishment mechanism. Then, the replenishment trolley 5 travels to a position opposite to the storage chamber 21 and finally, the replenishment mechanism puts the activated carbon powder into the storage chamber 21. The above structure has the following advantages: ① The automatic dispensing structure replaces manual dispensing, greatly improving dispensing efficiency and convenience; ② The transfer chamber 3 serves as the transfer point, where activated carbon powder is first uniformly transported to the transfer chamber 3, and then dispensed one by one by the dispensing trolley 5. Compared with the traditional method of setting independent activated carbon powder replenishment structures in each storage chamber 21, this greatly simplifies the pipeline structure; ③ The sealed dispensing system formed by the transfer chamber 3, replenishment pipeline 34, dispensing pipeline 4, and storage chamber 21, which is isolated from the outside world, is conducive to the long-term storage of activated carbon powder, thereby ensuring the pollutant adsorption effect of activated carbon powder; ④ The independently supported transfer chamber 3 greatly reduces the burden on the flue and extends the service life of the flue.

[0022] The driving mechanism includes a driving gear 52, a driving rack 42, a driving motor 53, and multiple guide wheels 54. The delivery trolley 5 is arc-shaped and slides into the internal structure of the delivery pipe 4. The inner wall of the delivery pipe 4 near the flue 1 serves as the driving side wall 44, and the inner wall away from the flue 1 serves as the guide side wall 45. The driving motor 44 is fixed to the delivery trolley 5 and drives the horizontally arranged driving gear 52 to rotate. The gear shaft of the driving gear 52 and the motor shaft of the driving motor 53 are linked together by a synchronous pulley 58 and a synchronous belt 59. The driving side wall 44 is provided with a gear guide groove 441 with the same thickness as the driving gear 52. The driving rack 42 is arranged circumferentially... The guide wheel 54 is placed in the gear guide groove 441 and meshes with the travel gear 52. The guide wheel 54 is horizontally set on the delivery trolley 5. The guide side wall 45 is provided with a guide wheel groove 451 with the same thickness as the guide wheel 54 and rolling cooperation with the guide wheel 54. The travel motor 53 drives the travel gear 52 to rotate, and then the travel rack 42 meshing with the travel gear 52 drives the delivery trolley 5 to move along the delivery pipe 4. At the same time, multiple guide wheels 54 are used. This solution preferably uses two to ensure that the delivery trolley 5 moves smoothly while the travel gear 52 and the travel rack 42 are stably meshed. In addition, the location of the storage compartment 21 can be accurately identified by sensors and marker points.

[0023] The dispensing mechanism includes a dispensing baffle 55, a dispensing track 56, and a dispensing motor 57. The dispensing track 56 is located inside the dispensing trolley 5 and is connected to the side of the dispensing chamber 51. The dispensing baffle 55 slides along the dispensing track 56. When the dispensing baffle 55 slides, it has a supplementary position that blocks the lower end of the dispensing chamber 51 and a dispensing position that is offset from the lower end of the dispensing chamber 51. A dispensing rack 751 is provided above the dispensing baffle 55 along the sliding direction. The dispensing motor 57 is fixed to the dispensing trolley 5 and drives a dispensing gear 571 that meshes with the dispensing rack 751. The dispensing motor 57 drives the dispensing gear 571 to rotate, which in turn drives the dispensing baffle 55 to slide back and forth through the dispensing rack 751 that meshes with the dispensing gear 571. This allows the dispensing chamber 51 to switch freely between the supplementary state and the dispensing state. The dispensing chamber 51 and the dispensing track 56 are asymmetrically designed relative to the center of the dispensing trolley 5, leaving a large space for the dispensing track 56.

[0024] It also includes a cleaning cylinder 43, which is fixed to the feeding pipe 4 and corresponds one-to-one with the storage chamber 21. A cleaning pusher plate 431 is driven below the cleaning cylinder 43 to extend into the feeding chamber 51 and completely push the activated carbon powder in the feeding chamber 51 into the storage chamber 21. The addition of the cleaning cylinder 43 drives the cleaning pusher plate 431 to extend into the feeding chamber 51 and completely push the activated carbon powder in the feeding chamber 51 into the storage chamber 21, so as to avoid the activated carbon powder remaining in the feeding chamber 51 and ensure that a sufficient amount of activated carbon powder is fed each time.

[0025] The bottom of the transfer chamber 3 is equipped with a guide ramp 35. The height of the guide ramp 35 gradually decreases from the powder inlet pipe 31 to the replenishment section 33. A vibrator 36 is installed on the outer side of the transfer chamber 3. The guide ramp 35, together with the vibrator 36, causes the activated carbon powder transmitted to the transfer chamber 3 to gradually approach the replenishment section 33, so that the replenishment section 33 has sufficient activated carbon powder. This ensures that enough activated carbon powder is replenished to the feeding chamber 51 each time. At the same time, it can also effectively prevent the activated carbon powder from clogging, bridging, or sticking to the wall.

[0026] The replenishment mechanism is a star-shaped unloader 37 located at the lower end of the replenishment pipe 34. Preferably, the star-shaped unloader 37 is used as the replenishment mechanism, which can efficiently replenish an equal amount of activated carbon powder and can automatically cut off the replenishment pipe 34 when the conveying stops.

[0027] In addition, a rechargeable battery 50 is installed inside the delivery vehicle to power various components. The power supply contact 501 on the outer wall of the delivery vehicle 5 and the power supply strip 46 on the inner wall of the delivery pipe 4 (which is consistent with the trajectory of the delivery pipe 4) are kept in contact, which constitutes the charging cooperation between the external power supply and the rechargeable battery and the transmission of control signals with the controller.

[0028] The aforementioned device has a controller that controls the coordinated operation of various electronic components. It can be controlled by wired or wireless means.
