Abstract
The utility model discloses a thermal hydrodynamic force driven online automatic cleaning scale-preventing device with a spiral toothed pipe. The device 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 toothed pipe, spiral teeth are arranged on the surface of the spiral toothed pipe, and the spiral toothed pipe is arranged in the heat transfer pipe. The rotatable spiral toothed pipe is arranged in the heat transfer pipe; in the hot fluid flowing process, the spiral toothed pipe can generate automatic continuous rotation, 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 screw geared tube on-line auto-cleaning of a kind of hot fluid 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 screw geared tube on-line auto-cleaning of a kind of hot fluid 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 screw geared tube, the surface of described screw geared tube is provided with helical tooth, and described screw geared tube places in the described heat-transfer pipe.
Further, described helical tooth is two, is evenly distributed on the surface of described screw geared tube.
As preferably, the external diameter of described helical tooth be described heat-transfer pipe internal diameter 4/5ths to 7/8ths; Best 5/6ths.
The beneficial effects of the utility model are:
The utility model is by rotatable screw geared tube is installed in heat-transfer pipe, and in the hot fluid flow process, screw geared tube can produce the Automatic continuous rotation, reaches 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
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings, the utility model is connected with heat-transfer pipe 5, be provided with bearing 1 on the port of the feed tube 2 of heat-transfer pipe 5, the center of bearing 1 is equipped with rotating shaft 3, the inner of rotating shaft 3 places in the feed tube 2, the inner of rotating shaft 3 is connected with an end of screw geared tube 6, and the surface of screw geared tube 6 is provided with helical tooth 7, and screw geared tube 6 places in the heat-transfer pipe 5; Helical tooth 7 is two, is evenly distributed on the surface of screw geared tube 6; The external diameter of helical tooth 7 be heat-transfer pipe 5 internal diameter 5/6ths.
As shown in drawings, during operation, hot fluid enters from the inlet 4 of feed tube 2, in heat-transfer pipe 5, flow along helical tooth 7, in the hot fluid flow process, screw geared tube 6 can be because the thrust of hot fluid produces the Automatic continuous rotation, and the helical tooth 7 of screw geared tube 6 inwall to heat-transfer pipe 5 in rotary course produces collision, reaches effective on-line auto-cleaning antiscale purpose.
