Abstract
The utility model discloses a thermal hydrodynamic force driven online automatic cleaning scale-preventing device of a helical toothed distorted band, which is connected with a heat transfer pipe. A feeding pipe port of the heat transfer pipe is provided with a bearing, a rotating shaft is arranged at the center of the bearing, the inner end of the rotating shaft is arranged in a feeding pipe, the inner end of the rotating shaft is connected with one end of the spiral distorted band, a plurality of helical teeth inclining in a direction away from the rotating shaft are uniformly arranged on the spiral distorted band, and the spiral distorted band is arranged in the heat transfer pipe. The rotatable spiral distorted band is arranged in the heat transfer pipe, and the helical teeth are arranged on the spiral distorted band; in the hot fluid flowing process, the spiral link can generate complicated movement mainly including automatic continuous rotation, helical teeth collide with the inner wall of the heat transfer pipe, and thus the purpose of online cleaning the inner wall of the heat transfer pipe is reached. Scales on the inner wall of the heat transfer pipe are cleaned online, thus the working efficiency of the heat transfer pipe is increased, and the economic loss caused by the scales on the inner wall of the heat transfer pipe is reduced.
Description
Technical field
The utility model relates to a kind of cleaning scale prevention device of heat-transfer pipe, relates in particular to the power-actuated helical teeth bond type of a kind of hot fluid on-line auto-cleaning scale prevention device.
Background technology
Heat-transfer pipe is widely used, and is very general in the electric power related application.The heat-transfer pipe inwall is owing to contacting with hot fluid for a long time, so than being easier to produce dirt, these dirts can have a huge impact heat transfer property.Take the steam turbine of thermal power plant as example, the fired power generating unit total capacity in the whole nation is calculated by 2.5 hundred million KW, and the loss total value that produces because of incrustation scale reaches annual more than 4,200,000,000 yuan.Take the refrigeration system of slaughtering processing industry as example, its serious inefficiency in vertical water cooler ditch, the economic loss every year that causes is about more than 2,000,000,000 yuan.Therefore, the internal dirt of heat-transfer pipe is processed and is had great importance.
The internal dirt treatment technology of existing heat-transfer pipe, take glueballs cleaning, Chemical cleaning, Electromagnetic Treatment, water treatment agent technology as main, the de-sludging effect of these technology is all good, but the defective that all has a maximum: when equipment is out of service, carry out de-sludging and process, normal operation affects greatly to equipment, reduce largely the equipment working efficiency, caused greater loss to industrial production.
Summary of the invention
The purpose of this utility model provides the power-actuated helical teeth bond type of a kind of hot fluid on-line auto-cleaning scale prevention device with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model is connected with heat-transfer pipe, be provided with bearing on the feed tube port of described heat-transfer pipe, the center of described bearing is equipped with rotating shaft, the inner of described rotating shaft places in the described feed tube, the inner of described rotating shaft is connected with an end of spiral band, evenly be provided with a plurality of helical teeth to tilting away from described rotor shaft direction on the described spiral band, described spiral band places in the described heat-transfer pipe.
Particularly, described spiral band is the plastic spiral tie, and described helical teeth is the plastics helical teeth.
As preferably, the thickness of described spiral band is 0.5-2cm; The best is 1cm.
Angle between the axial direction of described helical teeth and the axial direction of described spiral band is 30 °-80 °; The best is 55 °.
The beneficial effects of the utility model are:
The utility model is by installing rotatable spiral band in heat-transfer pipe, and at spiral band helical teeth is set, in the hot fluid flow process, spiral band can produce with Automatic continuous and rotate to be main compound movement, helical teeth and heat-transfer pipe inwall collide, and reach the purpose of on-line cleaning heat-transfer pipe inwall; The utility model has improved the heat-transfer pipe operating efficiency by on-line cleaning heat-transfer pipe internal dirt, has reduced the economic loss that causes because of the heat-transfer pipe internal dirt.
Description of drawings
