Wherein, can be seen that on the movement locus figure of heat exchanger cleaner plate(Fig. 2), heat exchanger cleaner plate in normal work
It is integrally fixed on the position of anchor point A, plays the effect of gripper shoe and deflection plate, cleaning is only just played in Qian Hou cleaning process
The effect of plate.There is sewage runner in cleaner plate, sewage flows through at ordinary times from sewage runner, and sewage runner has in heat exchanger
Two effects, one is to walk sewage, and two is the turbulent augmentation of heat transfer of manufacture.
When cleaning is needed, first chip sends instruction to motor according to cleaning distance,(Fig. 2)In can see
Go out, cleaner plate assembly has first fixing point A to move to switch-back point B to complete movement step 1, the cleaner plate outer rim in this motor process
A points to housing dirt between B points can be scraped milling totally, it is clean that the wiper ring in cleaner plate then scrapes milling the dirt on heat exchanger tube.
Second step, motor reversion makes cleaner plate adverse movement, is moved to switch-back point C from switch-back point B and completes motion step
Rapid 2, it is clean that cleaner plate outer rim and wiper ring then scrape milling switch-back point B to the dirt of the housing between switch-back point C and heat exchanger tube.
3rd step, motor is rotated forward makes cleaner plate return basic fixed position point A by switch-back point C, and final motion completes motion
Step 3, cleaner plate outer rim and wiper ring then scrape milling totally switch-back point C to the dirt of the housing between anchor point and heat exchanger tube,
Cleaner plate plays a part of gripper shoe and deflection plate and waits the finger of next cleaning circulation after anchor point is reached in anchor point
Order.
Referring to the drawings 2, can there are multiple gripper shoes and cleaner plate in a heat exchanger, they are according to uniform point of design
Match somebody with somebody.Example;(Fig. 2)Three cleaner plates are evenly distributed in heat exchanger by two pieces of gripper shoes in cleaner plate shuttling movement, when will
During motion, three cleaner plate motions are synchronous.
Gripper shoe is integrally fixed on heat exchanger shell, plays a part of to support and fixed heat exchanger tube, is seen(Fig. 1)(Fig. 2).
Heat exchange pore, sewage runner hole, leading screw axis hole, without lead screw shaft nut so not transporting with guide screw movement are provided with gripper shoe
It is dynamic, see(Fig. 5
Heat exchanger two is made up of tube sheet, and cleaner plate can be carried out scraping milling and removed in movement to heat exchanger tube and inner wall of tube shell
Dirt, but cleaner plate sewage runner is possible to be blocked by dirt in longtime running, so devise on the tube sheet at two can be with
The cleaning block of milling sewage runner is rushed, is seen(Fig. 6)(Fig. 7).Sewage runner cleaning block(P)External diameter is more smaller than sewage runner internal diameter,
Cleaning block is thinner than sewage runner, thickness of the length more than cleaner plate.
Citing 1 is in Fig. 2. and when switch-back point C is moved to, the sewage runner cleaning block on tube sheet just can be passed through cleaner plate G1
Sewage runner.Dirt in sewage runner is carried out to rush milling.Dirt under rinsing is taken away with sewage.Citing 2;Cleaner plate G3 is when fortune
When moving switch-back point B, the sewage runner cleaning block on tube sheet can just pass through sewage runner.Dirt in sewage runner is carried out
Rush milling.
The sewage runner cleaning of G3 gripper shoes can set hollow runner cleaning block in cleaner plate, you can with sewage stream
Cross, it is also possible to rush milling sewage runner to gripper shoe.
180 above cleaner plate(Cleaning panel guide location hole is diagonally provided with, for fixed cleaning in scraping milling campaign in cleaner plate
The movement locus of plate are walked before and after straight line.(Fig. 3)(Fig. 8)
Two rectilinear orbits are provided with heat exchanger inner wall of tube shell, and cleaner plate upper rail location hole is to be mapped.Be for
To the fixation that moved along a straight line of cleaner plate, the cleaner plate is allowed to scrape before and after in milling along track motion.Will not be with leading screw
Rotate and rotate.(Fig. 1)(Fig. 3)(Fig. 8)
Choose titanium material to make leading screw, cleaner plate and wiper ring, the internal diameter of wiper ring (Ge) is than heat exchanger tube (H) external diameter greatly slightly
There is gap.Wiper ring Ge is made up of two parts, and ring a and ring b wiper rings internal diameter take to form interval hollow structure at interval of 18 degree(Figure
9)Wiper ring structure chart.Such design is that wiper ring (Ge) and heat exchanger tube (H) are reduced while milling soils are scraped in acquirement
Scrape milling resistance.Wiper ring is made up of 18 degree of superpositions of ring a and the mutual rotational offset of ring b two parts(Figure 10)
One of each wiper ring can scrape the dirt area of milling heat exchanger tube 180 degree, and two for staggering wiper ring (Ge) just can be with
360 degree of milling heat exchanger tube is scraped while drag reduction is to minimum, heat exchanger tube (H) dirt is scraped totally.Left ring and the right ring back side with
Together with groove is mutually inlayed with tongue two sides, a kind of tight structure is formed(Fig. 9)(Figure 11).And be provided with surplus and can float,
This surplus design be for heat exchanger tube (H) production and alignment error, in order to increase wiper ring scrape on heat exchanger tube (H) milling lead to
The property crossed increases wiper ring (Ge) and scrapes milling ability to design.
Figure 12, illustrates heat exchanger heat-exchanging tube and installs and have certain error on producing, then wiper ring is scraping milling fortune
Disorder of internal organs can change the movement locus of oneself with bending up and down for heat exchanger tube, this is because wiper ring is enclosed within above heat exchanger tube
's.Cleaner plate assembly and wiper ring are to be flexible coupling.Cleaner plate is moved along the track of oneself.So cleaner plate total performance can be with
Move in the heat exchanger of many heat exchanger tubes H1, H2, H3, be unlikely to be stuck because of heat exchanger tube installation deviation.In cleaner plate
Heat exchange pore perforate be greater than the diameter of heat exchanger tube and be less than the external diameter of wiper ring.So cleaner plate both may be used in milling campaign is scraped
Dropped out with driving wiper ring motion to be unlikely to wiper ring again, in addition wiper ring has certain surplus in cleaner plate mounting design,
Wiper ring can be allowed smoothly movable in cleaner plate.See(Figure 12)Enlarged drawing.
Type of drive
Self-cleaning heat exchanger is by motor(C)Before and after (J) rotation driving of power leading screw is driven to complete cleaner plate (Gc)
Motion, outer rim of the cleaner plate in moving forward and backward carries out scraping milling scale removal to inner walls, while cleaner plate (Gc) drives wiper ring
(Ge) carry out scraping cleaning exchanging heat pipe (H).Tube sheet sewage runner cleaning block also carries out rushing milling to cleaner plate sewage runner.By
In the composition difference scale velocity of sewage also different, best opportunity of scale removal is when dirt is newly formed, so every kind of sewage
Scale removal can be realized interval time by timing controlled.Increased the suitability of the heat exchanger to various Sewage Environments.
