Description

Technical Field

[0001] This utility model relates to the field of solid waste transportation and treatment technology, and in particular to a solid waste harmless treatment device. Background Technology

[0002] In the field of solid waste harmless treatment, especially for wastes such as heavy metal sludge and incineration fly ash that ultimately require safe landfill, high-density polyethylene (HDPE) drums are commonly used for transportation and temporary storage. The conventional practice is to pack waste into sturdy HDPE drums, transport them to the landfill, dump the waste, and then return the empty drums for reuse. However, the existing HDPE drum transportation method has significant drawbacks:

[0003] 1. Empty barrel transportation is inefficient and easily damaged: Empty barrels after dumping waste are large in size and have no filling inside, which makes their center of gravity unstable. During transportation in the truck, empty barrels are very easy to roll and collide with each other, causing the barrel to break or deform, affecting their service life and sealing performance. In addition, empty barrels cannot be compressed, and they occupy a lot of truck space during return transportation, resulting in high transportation costs.

[0004] 2. Difficult to clean: The container comes into direct contact with solid waste, especially viscous or corrosive waste (such as heavy metal sludge and fly ash), which is very easy to leave residues on the inner wall and harden. HDPE containers are large and have a fixed structure, making internal cleaning extremely inconvenient. The residues not only affect the next use, but may also cause cross-contamination or emit odors.

[0005] Therefore, it is necessary to provide a new solid waste harmless treatment device to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a solid waste harmless treatment device.

[0007] The solid waste harmless treatment device provided by this utility model includes a barrel body and a barrel cover. The barrel body includes a barrel base, on which an elastic folding telescopic sleeve is fixedly installed, and on which a barrel mouth ring is fixedly installed.

[0008] The barrel body is equipped with a central connecting member, and the central connecting member includes a lower collar. Multiple multi-stage telescopic rods distributed in a ring are fixedly installed on the lower collar, and an upper collar is fixedly mounted on the top of the multiple multi-stage telescopic rods. The upper collar is fixedly installed on the outer wall of the barrel mouth ring, and the lower collar is fixedly installed on the outer wall of the barrel base.

[0009] The barrel is fitted with a double-layered thickened polyethylene bag.

[0010] Preferably, a magnetic ring A is fixedly fitted into the inner bottom wall of the bucket seat, and an inner ring groove is formed in the inner ring wall of the bucket mouth ring.

[0011] Preferably, the opening of the double-layer thickened polyethylene bag is fixedly fitted with a bag opening ring, and a magnetic ring B is fixedly fitted at the bottom of the double-layer thickened polyethylene bag, wherein the magnetic ring B has the opposite magnetism to the magnetic ring A.

[0012] Preferably, a pressure ring is fixedly installed on the inner surface of the bucket lid.

[0013] Preferably, the outer ring surface near the top of the barrel opening ring is provided with an external thread, and the barrel opening ring is fixedly connected to the barrel lid threadedly through the external thread.

[0014] Preferably, an annular protrusion is fixedly installed on the lower surface of the bucket base, and an annular groove that matches the annular protrusion is formed on the upper surface of the bucket lid.

[0015] Compared with related technologies, the solid waste harmless treatment device provided by this utility model has the following beneficial effects:

[0016] 1. This utility model, through the retractable design of the elastic folding telescopic sleeve and multi-stage telescopic rod, can press the barrel seat and barrel mouth ring together in the empty state, which significantly reduces the overall height of the barrel. After the multi-stage telescopic rod is retracted, it tightly surrounds the folded barrel body, which greatly reduces the volume of the empty barrel and the floor space occupied. More compressed empty barrels can be loaded during return transport, which improves vehicle utilization and reduces transportation costs. Moreover, the compressed barrel body has a compact structure and a stable center of gravity, which effectively avoids the problem of rolling collision during transportation.

[0017] 2. This utility model uses a detachable double-layer thickened polyethylene bag as a direct waste container. The waste does not directly contact the inner wall of the bucket. After dumping the waste, simply remove the double-layer thickened polyethylene bag containing contaminants from the bucket. The residue is mainly found in disposable or easy-to-clean plastic bags, and the inner wall of the bucket remains basically clean. This greatly simplifies the cleaning process and solves the problem of contamination and cleaning of the inner wall of the bucket. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 6 This utility model provides a solid waste harmless treatment device, which includes a barrel body 1, a barrel cover 2, a central connecting part 3, and a double-layer thickened polyethylene bag 4.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 6 The barrel body 1 includes a barrel base 11, on which an elastic folding telescopic sleeve 13 is fixedly installed. A barrel mouth ring 12 is fixedly installed at the upper end of the elastic folding telescopic sleeve 13. A central connector 3 is installed on the barrel body 1. The central connector 3 includes a lower sleeve ring 31. Multiple multi-stage telescopic rods 32 distributed in annular pattern are fixedly installed on the lower sleeve ring 31. An upper sleeve ring 33 is fixedly mounted on the top of the multiple multi-stage telescopic rods 32. The upper sleeve ring 33 is fixedly installed on the outer wall of the barrel mouth ring 12. The lower sleeve ring 31 is fixedly installed on the outer wall of the barrel base 11. An external thread 121 is opened on the outer ring surface near the top of the barrel mouth ring 12. The barrel mouth ring 12 is threadedly connected to the barrel lid 2 through the external thread 121.

[0029] It should be noted that: through the retractable design of the elastic folding telescopic sleeve 13 and the multi-stage telescopic rod 32, the barrel seat 11 and the barrel mouth ring 12 can be pressed together in the empty state (after waste dumping), which significantly reduces the overall height of the barrel body 1. After the multi-stage telescopic rod 32 is retracted, it tightly surrounds the folded barrel body, which greatly reduces the volume of the empty barrel and the floor space occupied. More compressed empty barrels can be loaded during return transport, which improves vehicle utilization and reduces transportation costs. Moreover, the compressed barrel body 1 has a compact structure and a stable center of gravity, which effectively avoids the problem of rolling collisions during transportation.

[0030] When loading processed solid waste, clamp the bucket seat 11 with both feet and pull the bucket seat 11 up, thereby stretching the elastic folding telescopic sleeve 13 to form the bucket body. At this time, the multi-stage telescopic rod 32 is also stretched. After the multi-stage telescopic rod 32 is stretched, it surrounds the bucket body, which not only avoids the hidden danger of the elastic folding telescopic sleeve 13 expanding laterally after the bucket body 1 is loaded with solid waste, but also provides support for the bucket mouth ring 12.

[0031] In this embodiment, the rods inside the multi-stage telescopic rod 32 are equipped with damping sleeves, so that the multi-stage telescopic rod 32 will not shrink after being stretched without the action of external force.

[0032] Furthermore, an annular protrusion 111 is fixedly installed on the lower surface of the bucket base 11, and an annular groove 2a that matches the annular protrusion 111 is opened on the upper surface of the bucket lid 2. The annular protrusion 111 of the bucket base 11 and the annular groove 2a of the bucket lid 2 cooperate to allow multiple compressed empty buckets to be stacked stably, further optimizing storage and transportation space.

[0033] Among them, the elastic folding telescopic sleeve 13 is made of elastic material with high wear resistance, weather resistance and excellent fatigue resistance (such as rubber with a specific formula or thermoplastic elastomer TPE) to reduce the risk of wear, aging or even breakage of the folded parts when the elastic folding telescopic sleeve 13 is repeatedly folded and stretched for a long time.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 6 The barrel body 1 is equipped with a double-layer thickened polyethylene bag 4. A magnetic ring A5 is fixedly embedded in the inner bottom wall of the barrel base 11. An inner ring groove 12a is opened in the inner ring wall of the barrel mouth ring 12. A bag mouth ring 41 is fixedly installed at the bag mouth of the double-layer thickened polyethylene bag 4. A magnetic ring B6 is fixedly installed at the bottom of the double-layer thickened polyethylene bag 4. The magnetic ring B6 has the opposite magnetism to the magnetic ring A5.

[0035] It should be noted that after the elastic folding telescopic sleeve 13 is stretched to form a barrel, the double-layer thickened polyethylene bag 4 is placed inside the barrel body 1. Since the bottom of the double-layer thickened polyethylene bag 4 is equipped with a magnetic ring B6, the magnetic ring B6 can be attracted to the magnetic ring A5. Then, the bag opening ring 41 is placed into the inner ring groove 12a. After that, the solid waste is filled into the barrel body 1.

[0036] Therefore, a detachable double-layer thickened polyethylene bag 4 is used as a direct waste container, so the waste does not directly contact the inner wall of the barrel 1 (elastic folding telescopic sleeve 13). After dumping the waste, it is only necessary to remove the double-layer thickened polyethylene bag 4 with contaminants from the barrel 1. The residue is mainly found in disposable or easy-to-clean plastic bags, and the inner wall of the barrel 1 is basically kept clean, which greatly simplifies the cleaning process and reduces the pollution and cleaning difficulties of the inner wall of the barrel 1. Since the double-layer thickened polyethylene bag 4 is a flexible structure, it is easier to clean the rubber high-density polyethylene barrel.

[0037] Furthermore, a pressing ring 21 is fixedly installed on the inner cover surface of the bucket lid 2 to facilitate pressing the bag opening ring 41 and improve the stability of the double-layer thickened polyethylene bag 4 inside the bucket body 1.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
