Abstract

The utility model relates to an automatic scale removal heat exchanger enhancement device which has a smaller operation resistance and will not be easily blocked by sundries, consisting of a spiral coil and a fixed stent. The two fixed metal wires on the spiral coil are connected with a linkage rod by connecting holes, the friction piece of the utility model is composed by a hollow cylindrical fixed ceramic friction piece embedded within the inlet of the fixed stent and a hollow cylindrical rotary friction piece provided for the inserting of the linkage rod. The spiral coil drives the linkage rod and the rotary friction piece to rotate together under the impulsion of the water flow. When the spiral coil is rotating, the water flow clung to the pipe wall can be strongly disturbed, the effect of heat exchanger enhancement is obvious, meanwhile, the scale and the slimy mud in the water flow can not be adhered to the pipe wall, so the pipe will not be scaled anymore, which can always keep clean. The utility model solves the problems that the spiral tie type automatic scale removal heat exchanger enhancement device has a stronger resistance and is easy to be blocked by sundries and can not rotate.

Description

Automatic descaling enhanced heat exchanger of helical coils
Affiliated technical field
The utility model relates to a kind of Automatic descaling enhanced heat exchanger of helical coils that is applicable to straight pipeline.
Background technology
The automatic desludging reinforced heat exchanger of straight pipeline is the spiral band type at present, and device resistance is bigger during operation, is stopped up and can not rotate by foreign material easily.
Summary of the invention
Bigger in order to solve spiral band type automatic desludging reinforced heat exchanger resistance, by the foreign material blocking problem, the utility model provides a kind of Automatic descaling enhanced heat exchanger of helical coils easily, and this installs, and not only running resistance is little, and be difficult for being stopped up by foreign material, operational reliability strengthens.
The technical scheme that its technical problem that solves the utility model adopts is: two fixing metal silks that are welded on the spiral winding are connected with connecting rod by connecting perforation, the pipe water mouth can be filled in and be fixed on to fixed support by hand, plays the bearing effect of connecting rod.Connecting rod provides axis of rotation and draw.The friction member of this device is formed by the fixing ceramic friction member of the interior hollow-cylindrical that is embedded in the fixed support import with for the interior hollow-cylindrical rotary ceramic friction member that connecting rod inserts.Spiral winding drives connecting rod under the current impulsion and the spin friction part rotates together.During the spiral winding rotation, the current of being close to tube wall obtain strong disturbance, and the enhanced heat exchange effect is obvious, and dirty class and the foundry loam in the current can not be attached to tube wall simultaneously, and pipeline is fouling no longer, remains clean state.The middle part of spiral winding is hollow, and resistance to water-flow is less, and foreign material also are flushed away easily.The crocking resistance and the decay resistance of nano ceramics are fine, and service life is very long.
The beneficial effects of the utility model are that the resistance of Automatic descaling enhanced heat exchanger of helical coils is little, is difficult for stopping up wear resistant corrosion resistant, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is a structural map of the present utility model.
Among the figure: 1. connect pole, 2. fixing ceramic friction member, 3. rotary ceramic friction member, 4. fixed support, 5. spiral winding 6. connects perforation, 7. fixing metal silk
The specific embodiment
In accompanying drawing embodiment, this device is made up of spiral winding 5 and fixed support 4, two fixing metal silks 7 on the spiral winding 5 are connected with connecting rod 1 by connecting perforation 6, and the pipe water mouth can be filled in and be fixed on to fixed support 4 by hand, 1 axis of rotation of connecting rod and draw.The friction member of this device is formed by the fixing ceramic friction member 2 of the interior hollow-cylindrical that is embedded in the fixed support import with for the interior hollow-cylindrical rotary ceramic friction member 3 that connecting rod inserts.Spiral winding 5 drives connecting rod 1 under the current impulsion and rotary ceramic friction member 3 rotates together.During spiral winding 5 rotations, the current of being close to tube wall obtain strong disturbance, and the enhanced heat exchange effect is obvious, and dirty class and the foundry loam in the current can not be attached to tube wall simultaneously, and pipeline is fouling no longer, remains clean state.
