specific Embodiment approach 1

[0041] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment, the pipe smoothie flushing device described in this embodiment, it includes smoothie launch equipment (1), smoothie generator (2), press-in pump (3), feed water tank (4), valve The input port of the smoothie launching device (1) is connected with the output port of the smoothie generator (2), and the input port of the smoothie generator (2) is connected with the pump (3 ) is connected to the output end of the press-in pump (3), and the input end of the pump (3) is communicated with the water supply tank (4).

specific Embodiment approach 2

[0042] Specific embodiment 2: This embodiment is a further limitation of the ice sand launching device described in specific embodiment 1.

[0043] The ice sand launching equipment (1) of the present invention communicates with the cleaned pipeline (14): a hole of Φ200 is drilled on the upper surface of the cleaned pipeline (14), and the ice sand launching device is connected through a steel tee (5), The ice sand launching equipment (1) pushes the ice sand into the pipeline, and the hydraulic pressure generated by the hydraulic pump makes the ice sand walk in the pipeline, and the friction between the ice sand and the pipeline wall is used for cleaning. The caliber of the inlet of the pump (3) should ensure that the smoothie can run at a suitable speed (0.7-2m / s) under the action of the propelling medium. The diameter of the smoothie is about 100mm, and the end with a large diameter of the smoothie launcher is 20-50% larger than the diameter of the smoothie, so that the smooth...

specific Embodiment approach 3

[0044] Specific embodiment three: this embodiment is a further limitation of the pipe smoothie flushing device described in specific embodiment one,

[0045] The pipeline ice sand flushing device according to the present invention also includes ice sand monitoring equipment (6). The smoothie monitoring device (6) consists of two parts: a signal transmitter installed at the entrance of the smoothie into the pipeline and a signal receiver at the outlet of the waste liquid discharge, to check whether the amount of smoothies emitted and received is equal.

Abstract

The invention discloses a pipeline ice sand flushing device and a pipeline ice sand flushing method. The pipeline ice sand flushing device consists of ice sand jetting equipment, an ice sand producer, a press-in pump, a water feeding basin, a valve, a pushing medium, ice sand monitoring equipment and the like. Facilities used in the pipeline ice sand flushing method comprise the pipeline ice sand flushing device and a series of auxiliary devices: a blockage analyzer, a pressure monitoring device, a flowmeter, an ice sand isotope tracking device and an ice sand passing indicator. The pipeline ice sand flushing device and the pipeline ice sand flushing method have the following advantages that the application range is wide, and no pollution and no corrosion are caused in a use process; in a pipeline flushing process, the position of ice sand can be accurately located, a state during ice sand moving can be mastered, and an ice sand blockage accident can be found and prevented; and the problems that an existing pipeline flushing device is poor in flushing effect, leads to pollution to water and an environment and cannot accurately locate the position of the ice sand due to insufficient pipeline friction or improper selection of a flushing medium are solved.

Description

technical field [0001] The patent of the present invention relates to a pipeline flushing device and a flushing method, in particular to a pipeline smoothie flushing device and a flushing method. Background technique [0002] Due to historical and economic reasons, the secondary pollution of pipe network is a common problem in my country's water supply enterprises. When the high-quality factory water reaches the user's faucet after long-distance transportation through the pipe network, the water quality has dropped significantly. Flushing the pipe network is one of the effective ways to maintain and improve the water quality of the pipe network and to reduce the secondary pollution of the pipe network. clog. Physical methods are currently widely used methods, including high-pressure water jet cleaning, ice pig cleaning, and ice crystal cleaning methods. Traditional pipe network cleaning methods have poor cleaning effects and serious waste of water resources. [0003] Exis...
