Description

Technical Field

[0001] This utility model relates to the field of incinerator technology, specifically to an ash unloading device used in an incinerator. Background Technology

[0002] Waste incineration is a process in which waste is reduced in volume through appropriate thermal decomposition, combustion, melting and other reactions, and then oxidized at high temperatures to become residue or molten solid matter. Waste incineration facilities must be equipped with flue gas treatment facilities to prevent heavy metals, organic pollutants and other pollutants from being discharged back into the environment. The heat generated by waste incineration can be recovered to achieve the purpose of waste resource utilization. At the same time, the solid ash generated by incineration needs to be collected and treated centrally. However, when existing incinerator ash unloading equipment is in use, some heavy metals or toxic dust may spill out when the ash chamber door is opened. Furthermore, since operators manually operate the slide gate valve at close range, the spilled dust can harm the human respiratory tract. If the slide gate valve is difficult to operate when the ash slag is blocked, it increases the time before the operator can open the ash chamber door. The heat wave that rushes out when the ash chamber door is opened will increase the operator's discomfort. Utility Model Content

[0003] The purpose of this utility model is to provide an ash unloading device for incinerators, which improves the safety of operators, eliminates direct contact between operators and high-temperature, high-dust environments, and prevents dust from overflowing, thereby providing a good working environment and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an ash unloading device for an incinerator, comprising: The ash storage box and the ash inlet pipe are integrally set on the upper surface of the ash storage box. The top of the inner cavity of the ash storage box is provided with a plate valve mechanism that controls the opening width of the connection channel between the ash inlet pipe and the ash storage box. The plate valve mechanism isolates the dust generated by incineration so that the ash storage box can cool and temporarily store the dust.

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an ash unloading device for an incinerator, comprising: Ash storage box 1, and ash inlet pipe 2 integrally installed on the upper surface of ash storage box 1. A plate valve mechanism 18 is provided at the top of the inner cavity of ash storage box 1 to control the width of the opening of the connection channel between ash inlet pipe 2 and ash storage box 1. The plate valve mechanism 18 isolates the dust generated by incineration so that the ash storage box 1 can cool and temporarily store the dust. The ash storage box 1 has an ash outlet 17 on one side, and a sealing structure is provided at the lower end of one side of the ash storage box 1 to seal the ash outlet 17. The sealing structure makes it difficult for dust to overflow from the ash outlet 17.

[0017] In this embodiment, the enclosed structure includes a left ash chamber door 7, a right ash chamber door 8, and a sealing plate 9. Two sets of guide rails 13 are provided on one side of the ash storage box 1. The left ash chamber door 7 and the right ash chamber door 8 are slidably mounted on the two sets of guide rails 13. The sealing plate 9 is fixedly connected to one side of the left ash chamber door 7. One side of the sealing plate 9 is in contact with one side of the right ash chamber door 8. The left ash chamber door 7 and the right ash chamber door 8 are each provided with a heat insulation plate 14 located inside the ash outlet 17 on the side opposite to the sealing plate 9. The left ash chamber door 7 and the right ash chamber door 8 are each provided with a handle 12 on one side. The ash outlet 17 is opened and closed by sliding the left ash chamber door 7 and the right ash chamber door 8 along the guide rail 13. The sealing plate 9 fits tightly to reduce dust overflow. The heat insulation plate 14 can block the high temperature inside the ash storage box 1 to prevent burns when the operator touches it. The handle 12 makes it easy to manually open and close the door. Overall, the reliability of the ash outlet 17 sealing and the safety of operation are improved. At the same time, the heat insulation plate 14 has a U-shaped cross section when viewed from above, which can restrict the movement of the left ash chamber door 7 and the right ash chamber door 8 to prevent them from falling off the guide rail 13. The guide rail 13 located on the lower layer is disconnected, which makes it easy for the dust falling on the guide rail 13 to be scraped off when the left ash chamber door 7 and the right ash chamber door 8 move.

[0018] Furthermore, it also includes two sets of fasteners 10 for fastening the sealing plate 9 to the right gray room door 8. Both sets of fasteners 10 include a latch 101 and a fastener block 102. The latch 101 is installed on one side of the sealing plate 9, and the fastener block 102 is fixedly connected to one side of the right gray room door 8. The locking 101 and the locking block 102 can fasten the sealing plate 9 and the right ash chamber door 8, further enhancing the sealing of the closed structure and preventing dust from leaking from the joint between the sealing plate 9 and the right ash chamber door 8 during the ash storage process. This improves the dust overflow prevention effect of the equipment and also prevents dust from directly overflowing when the left ash chamber door 7 and the right ash chamber door 8 are opened, thus playing a blocking role.

[0019] It is worth noting that the plate valve mechanism 18 includes two sets of guide frame beams 181, ash-blocking insert plate 182 and adjusting assembly. Both sets of guide frame beams 181 are fixedly connected to the top of the inner cavity of the ash storage box 1. The ash-blocking insert plate 182 is slidably inserted between the two sets of guide frame beams 181. Two sets of limiting blocks 19 are fixedly connected to the top of the inner cavity of the ash storage box 1. A fixing block 183 is fixedly connected to the lower surface of the ash-blocking insert plate 182. The ash-blocking insert plate 182, the ash storage box 1 and the ash inlet pipe 2 are all made of 304 stainless steel. By opening and closing the ash-blocking insert plate 182, a preliminary, non-absolute sealing isolation is achieved at the bottom of the incinerator before and after ash discharge, which reduces the loss of furnace temperature and the entry of external air to a certain extent. The guide beam 181 provides a stable sliding guide for the ash baffle plate 182. Its two ends are open to avoid dust blockage and ensure that it accurately controls the opening width of the ash inlet channel. The limiting block 19 can limit the sliding range of the ash baffle plate 182 to prevent excessive sliding from affecting the isolation effect. The ash baffle plate 182 can effectively isolate the high-temperature dust generated by incineration, provide conditions for the cooling and temporary storage of dust in the ash storage box 1, and reduce the impact of high temperature on the ash storage box 1.

[0020] Secondly, the adjusting assembly includes a threaded sleeve 184 and a lead screw 186. One end of the lead screw 186 is installed on one end of the threaded sleeve 184, and the other end of the threaded sleeve 184 is fixedly connected to one side of the fixing block 183. One end of the lead screw 186 passes through the ash storage box 1 and is fixedly connected to a handwheel 187. A corrugated pipe 185 that encloses the lead screw 186 is fixedly connected between the fixing block 183 and the ash storage box 1. The engagement of the lead screw 186 and the threaded sleeve 184 allows for precise adjustment of the position of the dust baffle plate 182, enabling flexible control of the ash inlet channel opening width. The handwheel 187 facilitates manual operation, reducing adjustment difficulty and device cost. The corrugated pipe 185 encases the lead screw 186, preventing dust from adhering to or entering the engagement gap between the lead screw 186 and the threaded sleeve 184, avoiding jamming, extending the service life of the adjustment assembly, and ensuring adjustment stability.

[0021] Specifically, a buffer guide plate 15 is fixedly connected to the inner cavity of the ash storage box 1 above the ash outlet 17, a ramp 16 is provided at the bottom of the inner cavity of the ash storage box 1 away from the ash outlet 17, and multiple sets of support legs 11 are fixedly connected to the lower surface of the ash storage box 1. The buffer guide plate 15 buffers the impact of falling dust, thereby reducing the dust in the dust storage box 1. At the same time, the ramp 16 can guide the dust at the bottom of the dust storage box 1 to gather towards the dust outlet 17, which is convenient for quick discharge during ash unloading. The support leg 11 provides stable support for the equipment, ensuring the overall stability of the equipment and improving operational safety.

[0022] It also includes an inspection mechanism 4, which includes an inspection window 41, a limiting angle plate 42, and a rotating clamping plate 43. A cleaning port 6 for hinged inspection window 41 is provided on one side of the ash inlet pipe 2. The rotating clamping plate 43 is rotatably inserted into one side of the ash inlet pipe 2. The limiting angle plate 42 is fixedly connected to one side of the inspection window 41. Multiple sets of auxiliary support beams 5 are fixedly connected to the bottom of the inner cavity of the ash inlet pipe 2. A docking plate 3 is provided at the upper end of the ash inlet pipe 2. For example, the inspection window 41 enables the inspection and cleaning of ash accumulation inside the ash inlet pipe 2 through the ash cleaning port 6. The rotating clamp 43 and the limiting angle plate 42 can quickly fix or open the inspection window 41, making operation convenient. The auxiliary support beam 5 enhances the structural strength of the ash inlet pipe 2, preventing deformation due to dust impact or stress. The docking plate 3 facilitates the precise docking of the ash inlet pipe 2 with the incinerator, improving the convenience and adaptability of equipment installation.

[0023] During use, the ash inlet pipe 2 is connected to the incinerator via the docking plate 3 to receive the dust generated by incineration. Check whether the ash transport vehicle is positioned directly below the ash discharge port, clear surrounding obstacles, and the ash baffle plate 182 on the top of the ash storage box 1 slides in the guide frame beam 181. The position is adjusted by the distance adjustment component to control the opening width of the ash inlet channel, thereby isolating the dust from the incinerator. If the ash discharge is not smooth (bridging or bridging occurs), the operator opens the maintenance mechanism 4 and uses a slag-pouring rod to poke through the ash cleaning port 6 or the gap of the ash baffle plate 182 to force the ash to fall. After completion, the maintenance mechanism 4 is closed and the ash baffle plate 182 is sealed, so that the dust in the ash storage box 1 is isolated from the incinerator and cooled for temporary storage. During the ash storage process, the ash outlet 17 is closed along the guide rail 13 through the left ash chamber door 7 and the right ash chamber door 8. The sealing plate 9 is fitted and sealed, and the fastener 10 is tightened and sealed. Together with the heat insulation plate 14, the high temperature is blocked to prevent the dust from overflowing. When unloading ash, open the closed structure. The ramp 16 at the bottom of the ash storage box 1 guides the dust to gather at the ash outlet 17. The buffer guide plate 15 reduces the impact of dust on the ash outlet 17, making it easier for the dust to be discharged. The ash and slag fall into the ash transport vehicle or collection container below. Clean up the ash and slag scattered on the ground, keep the work site clean, transport the fully loaded ash transport vehicle away, and replace it with an empty vehicle to prepare for the next operation.

[0024] It is worth noting that operators wear a full set of personal protective equipment, including but not limited to: heat-resistant gloves, dust masks (or respirators), goggles, safety helmets, and puncture-proof safety shoes. They also check that the ash transport vehicle is positioned directly below the ash outlet 17, clear surrounding obstacles, and prepare auxiliary tools such as slag removers and shovels.
