Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, and to a mobile pneumatic waste processor for compressing, dehydrating and baling household waste generated on various public transportation vehicles. Background Technology

[0002] The current method for handling municipal solid waste involves sorting, compressing, and dehydrating it before transporting it to landfills and waste-to-energy plants. Because municipal solid waste is large in volume and scattered, many existing technologies for compressing and dehydrating waste utilize compressed air. These technologies typically employ garbage bins with pistons, which, propelled by compressed air, compress and dehydrate the waste from above or below. However, their structures are complex, require significant space, and are only suitable for use at waste collection stations.

[0003] Kitchen waste compactors used on passenger aircraft (such as patent applications 2013800607535 and 2019215401031) all use mechanical force to compress waste. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile pneumatic garbage disposal unit that can be used on various public transportation vehicles such as land, sea and air. It uses gas pressure to compact and compress the garbage after simple sorting, and discharge the liquid in it, thereby reducing its volume and odor. After packaging and bundling, it will not bounce back and loosen when taken out. It can be stored on site for a short time and transported in a timely manner.

[0005] The technical solution of the present invention is: a mobile pneumatic garbage disposal unit, comprising a cylinder cover 1 and a cylinder body 2. The cylinder cover 1 is fitted with an observation window 3. The cylinder cover 1 is connected to the cylinder body 2 via a hinge 4. The cylinder body 2 is provided with a latch 5 that can fasten the cylinder cover 1. A drain pipe 6 and an operation panel 7 are provided on the side wall of the cylinder body 2. The drain pipe 6 communicates with the interior of the cylinder body 2. A tubular piston 8 that can reciprocate along the cylinder body 2 is provided inside the cylinder body 2. A positioning ball 9 is provided on the tubular piston 8. A detachable strapping 10 is fitted onto the positioning ball 9. A sealing ring is fitted to contact the inner wall of the cylinder body 2. The sealing ring includes an upper silicone sealing ring 11 located at the upper end of the tubular piston 8 and a lower silicone sealing ring 12 located at the lower end of the tubular piston 8. A miniature air compressor 13 is installed on the outer surface of the cylinder body 2. An air inlet 14, an exhaust valve 15, a pressure sensor 16, and support feet 17 are provided at the bottom of the cylinder body 2. The air inlet 14 is connected to the miniature air compressor 13 through a pipe. The miniature air compressor 13, the exhaust valve 15, the pressure sensor 16, and the operation panel 7 are electrically connected. Multiple support feet 17 are provided around the bottom of the cylinder body 2.

[0006] Preferably, the tubular piston 8 is a closed annulus, or the tubular piston 8 has an opening at its bottom, and ribs are provided at the opening. The ribs are connected to the inner sidewall and the inner top wall of the tubular piston 8.

[0007] Preferably, the lower surface of the cylinder head 1 is provided with a plurality of wedge-shaped blades 19. The wedge-shaped blades 19 are capable of cutting larger plastic waste. The height of the wedge-shaped blades is less than the thickness of the compressed waste block.

[0008] Preferably, the strapping 10 is cross-shaped.

[0009] Preferably, each of the support legs 17 is provided with a roller 18 at its bottom.

[0010] Preferably, the bottom of the cylinder 2 is a downwardly convex arc shape.

[0011] The working principle of the mobile pneumatic garbage disposal unit is to use compressed air to push the tubular piston 8 to compress and dehydrate the garbage above the piston. The workflow is as follows: S1, open the cylinder cover 1, press the jog switch of the micro air compressor to raise the tubular piston 8 to the upper edge of the cylinder 2, clean the piston surface, and then attach the strapping 10 to the positioning ball 9. S2, open the exhaust valve 15 to allow the tubular piston 8 to slowly fall back to the bottom of the cylinder 2, and then close the exhaust valve 15. S3, place a plastic garbage bag into the cylinder 2, fixing the opening of the garbage bag to the cylinder rim and ensuring the bottom reaches the tubular piston 8, then pour in the garbage until it is full. The surface of the positioning ball 9 is smooth and will not puncture the garbage bag. S4, cover the cylinder head 1, fasten the buckle 5, start the micro air compressor 13, compressed air enters the cylinder through the air inlet 14. Due to the effect of the silicone sealing ring 13, the compressed air pushes the tubular piston 8 to move upward to compress the garbage in the bag. The garbage in the bag is not evenly distributed and the compressive strength is also different. The tubular piston 8 has a large contact surface with the cylinder wall, which plays a guiding role. Its greater strength can overcome the uneven compressive strength and will not tilt or get stuck. Air is discharged from the edge of the unsealed cylinder head 1, and liquid flows out from the drain pipe 6. The garbage is gradually compressed. When the predetermined pressure value is reached, the pressure sensor 16 sends a stop signal and shuts down the air compressor. After a period of time, the operator observes through the observation window. If it is believed that the garbage has been compacted and there will be no significant rebound after decompression, the operator opens the exhaust valve 15, pulls down the latch 5, opens the cylinder head 1, and then immediately closes the exhaust valve 15 to prevent the tubular piston 8 from falling. Then, the garbage bag containing the garbage is tied tightly with the strapping 10 on the tubular piston 8 and taken out. After cleaning the surface of the tubular piston 8, the mobile pneumatic garbage disposal unit can accept new garbage again.

[0012] Compared with related technologies, the beneficial effects of the present invention are as follows: I. This invention has no mechanical transmission parts, making it less prone to failure and ensuring safe and reliable operation.

[0013] Second, the present invention has a high pressure per unit area, resulting in good compression and dehydration effects.

[0014] Third, the present invention compresses and immediately packages and tightens the garbage bag, so that the garbage bag will not bounce and loosen, which is convenient for short-term storage and timely transfer.

[0015] Fourth, the present invention has a compact structure, occupies little space, is hygienic and safe to use, and can also be made aesthetically pleasing, making it suitable for use on various public transportation vehicles with limited space. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" used below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0019] like Figures 1-5As shown, a mobile pneumatic garbage disposal unit consists of a cylinder cover 1 and a cylinder body 2 made of stainless steel sheet. The cylinder cover 1 is 30mm thick and has a double-layer structure, with a tempered glass observation window 3 embedded in the beveled circular hole in its center. The cylinder body 2 is 1000mm high, and its side wall is equipped with a drain pipe 6 and an operation panel 7. Inside the cylinder body 2 is a tubular piston 8 with a silicone sealing ring. The tubular piston 8 is 40mm high, hollow inside, and sealed at both ends with 5mm thick stainless steel plates. A 600W Delixi oil-free silent miniature air compressor 13 is installed on the outer surface of the cylinder body 2. The arc-shaped bottom of the cylinder body 2 has an air inlet 14, an exhaust valve 15, and a pressure sensor 16. All of the above-mentioned components and valves are operated on the operation panel 7. The maximum pressure inside the cylinder body 2 is 0.2 MPa, the compression force is 2 tons, and the compression time depends on the type of garbage.

[0020] This invention is a mobile device that can compress, dehydrate, and package various types of household waste generated on public transportation vehicles. The processed waste will not rebound and can be stored on-site for a short period of time before being transferred at an appropriate time. No waste will be spilled during the transfer.

[0021] This invention can be used on passenger trains, which can reduce the amount of cleaning required on trains and platforms, and help maintain a clean train environment.

[0022] Due to time differences, tens of thousands of ships of all sizes sail across the world's oceans at any given time. However, only very large ships with large crews and long voyages, such as cruise ships and aircraft carriers, have their own sewage and garbage treatment plants. The World Maritime Organization strictly prohibits the dumping of garbage, especially plastic waste, into the sea. However, once ships leave territorial waters, supervision is lacking, resulting in more than 8 million tons of new plastic waste being added to the global oceans every year, forming a huge plastic garbage island in the central Pacific Ocean. This harms fish, microplastics, and even humans. If this invention is widely used on ships, garbage can be processed on-site, and the resulting dry waste blocks can be temporarily stored on board and transferred to shore when docking. This prevents the generation of plastic waste at its source and protects the marine environment.

[0023] This invention can also be used on passenger aircraft, especially transoceanic passenger aircraft that generate a large amount of food waste.
