Embodiment Construction

[0018] The embodiment is a two-cylinder suction device, which is used for suction and transportation of municipal sludge.

[0019] Municipal sludge is a kind of high liquid limit silty organic soil, which is neither solid nor liquid, and belongs to the category of Bingham body in plastic state. This kind of sludge is in a plastic state and flowing state. It has the characteristics of smelly, sticky, soft and black. It pollutes the air and pollutes the environment. In the past, there was no suitable sludge suction device, which has always been an urgent problem to be solved in the project.

[0020] Such as figure 1 As shown, it includes working cylinder (1), reversing lever (2), reversing oil cylinder (3), cylinder head plate (4), wear plate (5), cutter ring (6), suction port (7) , film liquid ring nozzle (8), J-shaped tube (9), positioning bearing (10), spring leaf (11), sealing cover (12), positioning bracket (13), bearing bush (14), hoop ( 15), joint (16), feeding pipeline...

Abstract

The invention relates to an environment-friendly suction and conveying device for conveying of a sludge pipeline. The environment-friendly suction and conveying device comprises a working cylinder, a reversing valve, a suction head, a surface film liquid spray nozzle, a material conveying pipeline, a joint and a sealing outer cover. The environment-friendly suction and conveying device is used for suction and conveying of sludge in a plastic state and a flow state, namely soil with natural water content of more than a plastic limit. The environment-friendly suction and conveying device aims at shortening suction distance, preventing air suction, realizing the conversion of the working cylinder, improving suction and conveying speed and solving the problems of difficulty in suction and conveying of the sludge conveyed by the pipeline and secondary pollution in transportation. The environment-friendly suction and conveying device is not only suitable for transportation of earthwork, as well as clearing and transportation of urban sludge, but also capable of realizing a wide range of applications in petroleum, chemical industry, mining, water conservation and construction projects.

Description

technical field [0001] The invention is an environment-friendly suction and delivery device for sludge pipeline transportation, which relates to non-cow flow-Bingham body (Bingham) transportation technology. Background technique [0002] In reservoirs, lakes, and river courses, over time, thicker and thicker mud layers are gradually deposited, raising the river bed. This not only reduces storage capacity, pollutes the environment, and affects traffic, but also causes floods to flood during the flood season, endangering embankments and causing floods. In addition, industrial by-products and wastes such as primary coal slime, municipal sludge, and papermaking sludge are involved in the pipeline transportation of soft and sticky materials similar to silt in many aspects such as petroleum, chemical industry, mining, and environmental protection. It can be seen that the sludge pipeline transportation equipment has broad market demand and broad application prospects. [0003] Si...
