Description

Negative pressure pipeline transportation scattered garbage collection device and method

technical field

The invention relates to a pipeline transportation and automatic collection system, in particular to a negative pressure pipeline transportation scattered garbage collection device and method.

Background technique

During the collection, transportation and treatment of domestic waste, during equipment transportation and at the handover point of equipment, garbage and sewage will often be scattered, such as small garbage stations, transfer stations, etc. Small garbage stations and large transfer stations are the joint points connecting the source of garbage generation and the terminal disposal system, and play the role of transition. As one of the main schemes for processing urban waste collection, the ultimate goal is to make the garbage in the process of transfer Improve the compactness of the garbage in the compartment of the large garbage truck, turning bubbles into solids. However, due to the particularity of domestic waste components, no matter how advanced the transfer equipment is in the processing process, some parts of the garbage will be scattered in the workshop of the transfer station when the compressor and the garbage container are working, causing secondary pollution to the environment, and Workers in the workshop will also cause a certain degree of harm.

So far, only manual cleaning methods can be used, that is, manual cleaning, water washing, etc., which consume a lot of manpower and water resources.

Contents of the invention

The purpose of the present invention is to develop a comprehensive treatment system for garbage compression and transfer, a garbage sorting system and an automatic garbage collection system that are in the leading position in the world according to the international advanced technology. Relying on the rich experience in garbage collection and treatment for many years and its own technical advantages, the most advanced vacuum garbage collection system in the world is improved, and the technology is improved to provide a novel structure negative pressure pipeline transportation scattered garbage collection device and method.

In order to achieve the above purpose, a negative pressure pipeline transportation scattered garbage collection device is designed, including garbage collection and transportation pipelines, garbage separators, dust removal and deodorization equipment, and a computer control system. It is characterized in that one end of the exhaust pipeline is connected to the exhaust pipe of the vacuum pump of the fan unit One end of the suction pipe of the vacuum pump of the fan unit is connected to the upper part of the garbage separator device, and the left side of the garbage separator is connected to the garbage conveying pipe. There are several garbage collection points on the garbage conveying pipe, and there is a pipeline under the garbage separator, and one end of the pipeline is separated from the garbage. There is a knife gate valve between the containers, the other end of the pipeline leads to the unloading chute in the pit, the garbage compressor is connected under the unloading chute, the outlet of the compressor is connected to the garbage container body, the collection port device, the garbage separator device The vacuum pump device of the fan unit is equipped with a computer control system. The starting signal and the control signal of the computer are taken out from the memory at the same time. The starting signal is used to synchronize the input signal of the computer and control the communication between the starting signal and the output of the collection device, the separator device, and the vacuum pump of the fan unit. The signals are synchronized, and the computer system displays and controls the signals; the garbage conveying pipe is equipped with machine mouth collection points, chain plate collection points, fuselage collection points, and machine tail collection points, and each collection point is equipped with a knife gate valve;

Use negative pressure to collect garbage, use the front-end collection port arranged at the designated position to collect the scattered garbage generated during the garbage compression process, and use the negative pressure generated by the fan unit to suck the collected scattered garbage into the pipeline, and send it to the garbage separation through the conveying pipeline After gas-solid separation, it is sent back to the unloading chute of the transfer station. The conveyed gas after solid-gas separation will be connected to the tail gas treatment system of the transfer station, and will be discharged outdoors after treatment.

Negative pressure pipelines are used to transport scattered garbage collection devices, which can automatically collect scattered garbage generated in individual parts of small garbage stations and garbage transfer station workshops and send them back to the unloading chute to avoid scattered garbage staying in the workshop for a long time. Secondary pollution to the environment and harm to staff. Because it is an automatic collection device, manual cleaning and water washing are avoided, which reduces the workload of manpower and water consumption.

Compared with the prior art, the present invention is easy to operate, can effectively monitor the entire garbage disposal procedure, is humane and environmentally friendly, greatly reduces the pollution of scattered garbage, and at the same time has higher collection efficiency, lower costs, and can adjust the power of the vacuum pump. In addition to greatly reducing electricity consumption, it can also reduce the wear and tear on the garbage conveying pipes, and at the same time can greatly reduce labor costs and related expenses.

Detailed ways

The docking position of the machine room of the small garbage station will cause garbage and sewage to scatter during collection and transportation. Daily domestic waste is collected to the transfer station by special vehicles, put into the pit of the discharge chute of the transfer station through the feeding workshop, and then transferred to the garbage compressor by the mechanical transmission device for compression, from foam to solid. During the compression process, when the compression is completed, the garbage transfer box and the compressor are separated, and a small amount of garbage will be scattered.

When the scattered garbage collection device is installed, the scattered garbage will fall into the pre-set collection port and be temporarily stored for a short time. When the scattered garbage reaches a certain amount, the fan of the scattered garbage collection system will start to make the conveying A certain negative pressure airflow is generated in the pipeline, and then the control valve at the collection port is opened, and the temporarily stored garbage will be sucked into the pipeline by the negative pressure and move in the pipeline with the airflow, and will be transported to the upper part of the discharge chute to the garbage separator for disposal. Separation of gas and solids, the separated solids are sent back to the feeding and unloading tank through the discharge pipe at the lower part of the separator, and then sent to the compressor for compression, the separated gas is sent to the dust removal and deodorization equipment through the exhaust pipeline for treatment, and finally discharged to the outside.

The above is the production process of the whole negative pressure pipeline conveying scattered garbage collection device.
