Description

Technical Field

[0001] The utility model relates to a sewage cleaning and suction truck, in particular to a sewage cleaning and suction truck with a vacuum intercommunication function. Background Art

[0002] Driven by urbanization, the improvement of urban infrastructure and the maintenance of environmental sanitation have become crucial metrics for measuring a city's development. Sewer systems, industrial wastewater treatment, and the cleaning of various sewage pools are becoming increasingly important as key components in ensuring a healthy urban environment and the quality of life for residents. As specialized equipment in this field, the technological advancement and enhanced application efficiency of sewage cleaning and suction trucks are directly linked to the effectiveness and efficiency of environmental protection efforts.

[0003] In the context of the current rapid development of the cleaning industry, sewage cleaning and suction trucks are an important tool for maintaining urban environmental sanitation. Their technical level and application effect directly affect the efficiency and quality of urban cleaning. With the improvement of environmental awareness and the promotion of technological innovation, sewage cleaning and suction truck technology is developing in the direction of greater efficiency, greater environmental protection, and greater intelligence.

[0004] Existing sewage cleaning and suction trucks have two tanks: a clean water tank and a dirty water tank. The dirty water tank primarily uses a vacuum pump to extract air from the tank, creating a vacuum, and then sucks out the dirty water. The clean water tank primarily stores clean water for pipe cleaning. There are two ways to fill the clean water tank: one is to draw water from the manhole cover on the top of the tank; the other is to draw water from a fire hydrant on the side of the tank. A problem with existing sewage cleaning and suction trucks is that water access is limited, making it inconvenient and inefficient. Summary of the Invention

[0005] The utility model aims to provide a cleaning and suctioning sewage truck with a vacuum intercommunication function, which increases the vacuum intercommunication function between the two tank bodies of the cleaning and suctioning sewage truck, so that the clean water tank can achieve the purpose of self-priming water and improve work efficiency.

[0006] In order to solve the above technical problems, the technical solutions of the present invention are as follows:

[0007] A sewage cleaning and suction truck with a vacuum interconnection function includes a tank body, and is characterized in that: a partition is provided inside the tank body, and the tank body is divided into a clean water tank and a sewage tank by the partition; a vacuum pump is provided under the tank body, and a vacuum interconnection ball valve connecting the clean water tank and the sewage tank is provided on the top of the tank body, and a vacuum is formed in both tank bodies through the vacuum interconnection ball valve.

[0008] Improvement on the above technical solution: the vacuum interconnecting ball valve comprises a vacuum ball valve, and pipelines are provided at both ends of the vacuum ball valve.

[0009] Further improvement to the above technical solution: openings are provided on the tops of the tank bodies corresponding to the clean water tank and the sewage tank, and the pipes at both ends of the vacuum ball valve are respectively connected to the openings.

[0010] A further improvement to the above technical solution: the vacuum ball valve is connected by a quick-release flange connection, a slip-on flange connection, or a threaded connection.

[0011] Further improvement to the above technical solution: a valve is provided inside the vacuum ball valve of the vacuum interconnecting ball valve, and the valve is a straight-through type, and the straight-through valve is sealed by a spherical surface.

[0012] A further improvement to the above technical solution: the vacuum pump exhaust pipeline is directly connected to the sewage tank, and the vacuum pump operates to evacuate the sewage tank. When the top vacuum interconnecting ball valve is in a closed state, the clean water tank is in a normal pressure state and the sewage tank is in a vacuum state; when the vacuum interconnecting ball valve is in an open state, both the clean water tank and the sewage tank are in a vacuum state. Beneficial effects

[0013] When using the cleaning and suctioning sewage truck with vacuum interconnection function described in the utility model, a straight-through ball valve is used to connect the two independent tank bodies of the clean water tank and the sewage tank, so that vacuum can be formed in both tank bodies. The vacuum pump exhaust pipeline is directly connected to the sewage tank, and the vacuum pump operates to evacuate the sewage tank. If the top vacuum interconnection ball valve is closed, the clean water tank is in a normal pressure state, and the sewage tank is in a vacuum state. When the vacuum interconnection ball valve is opened, both tank bodies can be in a vacuum state. At this time, a fire hose can be used to connect the fire interface on the side of the tank body, and vacuum self-priming water can be used from water storage spaces such as ponds, ditches, and buckets. In this way, the vacuum interconnection function of the two tank bodies of the cleaning and suctioning sewage truck can be realized, which increases the storage options. In addition, the clean water tank can also use this function to achieve self-priming water operation, thereby improving the environmental adaptability of the suctioning sewage truck.
