Description

Movable jet water-flow cleaning device for round pipe

The utility model relates to a kind of water-jet type cleaning device of novel cleaning circular pipe.It belongs to the improvement to hydraulic jet machinery in the hydraulic engineering.It mainly is that cleaning spray tool by special construction is with pressure liquid pump links and the power-driven mechanism of special use reaches cleaning purpose to pipe to be cleaned.

At present, in oil industrial and mineral and petroleum chemical enterprise, Fouling Cleaning to the pipe surfaces externally and internally generally all is the method that adopts hot water to boil bubble and soak with the chemical agent class, promptly in fermentation vat, add a certain amount of chemical, oil pipe is inserted soak in the pond and Xiang Chizhong feeds heat steam and heats.This method is cost height, a large amount of cleaning agent class, heat and the length consuming time of consumption both, easily causes serious environmental to pollute again.As the interior pipe snaking of the oil recovery factory in the oil industrial and mineral, wax removal, logical stifled etc. all be the method that adopts pickling and power auger to scrape, wherein cost height, the environmental pollution of acid washing method are serious, and the method efficient that power auger is scraped is low, labor strength big, the noise dust pollution is serious.

The purpose of this utility model provides a kind of jet of movable type water rapidly and efficiently pipe cleaning device of both having saved the energy non-environmental-pollution with regard to being to avoid above-mentioned the deficiencies in the prior art part.To be the hydraulic blow energy that adopts high-pressure water jet clean the surfaces externally and internally of various pipes for it, its principle is that liquid is after the pressure liquid pump supercharging, enter by high pressure line in the cleaning spray tool of particular design, the high-speed jet that inside and outside cleaning shower nozzle in the cleaning spray tool ejects acts directly on the surfaces externally and internally of pipe to be cleaned, thereby reach the purpose that attachments such as greasy dirt to the surfaces externally and internally of pipe, incrustation, long-pending wax, rust clean, do not damage the metal surface.This device mainly partly is made up of pressure liquid pump, cleaning spray tool, reversal valve and base etc., promptly cleaning the spray tool links by high pressure line and reversal valve and pressure liquid pump, and the axis of the top that places base and pipe to be cleaned is relative and put, and makes pipe to be cleaned and clean the relative motion of spray tool.

Accompanying drawing 1 is overall structure schematic diagram of the present utility model.

Accompanying drawing 2 is and cleans shower nozzle (b) in of the present utility model, cleans the structural representation of shower nozzle (a) outward.

Working section schematic diagram when accompanying drawing 3 is of the present utility model the cleaning.

The drawing of accompanying drawing is described as follows:

1 ┄ pipe 2 ┄ driving rolls to be cleaned, 3 ┄ washout shower nozzles, 4 ┄ wash-in shower nozzles

5 ┄ high pressure lines, 6 ┄ fixed supports, 7 ┄ bases, 8 ┄ reversal valves

9 ┄ pressure liquid pumps, 10 ┄ annular spaces, 11 ┄ washout jet orifices, 12 ┄ wash-in jet orifices

In order to realize above-mentioned purpose of the present utility model, the cleaning spray tool of design person's design is mounted on the adjustable for height support (6), and is fixed on the base (7), its clean spray tool by washout shower nozzle (3) and in wash shower nozzle (4) and form; During work, washout shower nozzle (3) places the outside of circle pipe to be cleaned (1), and interior cleaning shower nozzle (4) places the inboard of circle pipe to be cleaned (1); Washout shower nozzle (3) and in wash shower nozzle (4) and link by high pressure line (5) and reversal valve (8) and pressure liquid pump (9) respectively; The structure of its washout shower nozzle (3) be on the inwall of annular space (10) inwardly and axis form an angle and offer some washout jet holes (11); In wash shower nozzle (4) structure be on the inwall of its shower nozzle, outwards to form an angle to offer with axis somely to wash jet hole (12) in individual, the visual supporting spring that it needs situation to be provided with to play a supportive role also on the outer wall washes in it that shower nozzle (4) also can be designed to around its axis rotation as required; Be provided with driving circle to be cleaned on its base (7) and manage (1) relative driving roller (2) that sprays the tool motion that cleans, the axis of the axis of its driving roller (2) and round pipe to be cleaned (1) is perpendicular.

Come enumeration design feature of the present utility model below in conjunction with specific embodiment:

In actual design was made, the designer offered several inside jet orifices on the inwall of the annular space of the washout shower nozzle that cleans the spray tool, and the shape of its jet orifice, size, quantity and injection direction and angle can be decided according to specific requirement; Offer the jet orifice of plurality of outward on the inwall of the wash-in shower nozzle of its cleaning spray tool, the shape of its jet orifice, size, quantity and injection direction and angle can be decided according to specific requirement, and certainly whether on its outer wall, add some supporting springs according to on-the-spot actual needs, look actual requirement and also the runner of wash-in shower nozzle can be designed to eddy channel; With inside and outside wash shower nozzle by high pressure line with after reversal valve connects, link with pressure liquid pump again; Then, cleaning the spray tool is fixed on the adjustable for height support.Several are set above on the base are used to drive the driving rolls that pipe to be cleaned cleans the motion of spray tool relatively, the reduction box of these driving rolls and motor links by transmission mechanism, can do to rotate synchronously and reciprocating motion.When cleaning operation, driving rolls drives pipe to be cleaned and moves reciprocatingly like this, makes the motionless cleaning spray tool and the pipe relative motion to be cleaned of motion, and then the inside and outside multiply high-pressure fluid that is ejected by cleaning spray tool just carries out the fluid power cleaning to the pipe of motion.Simultaneously, can control reversal valve as required, both can clean the inside and outside surface of pipe simultaneously, can clean the inner surface or the outer surface of pipe again separately.

The advantages such as the special hydraulic that adopts owing to the utility model cleans mechanism, need not to add chemical, also need not burning boiler and any fuel, and has efficient height, low, the non-environmental-pollution of cost, can realize automation cleaning operation, and labor strength is low. Only needing to make to clean medium with clear water gets final product. Clean 300～400 oil pipes every day by the oil recovery factory of present oil industrial and mineral and calculate, single cleaning agent expense of just saving and the fuel expense of steam boiler just can be an oil recovery factory every year and save 30～400,000 yuan.
