As shown in figs. 5 and 6, the first boss is equipped with the first guide rail 211a in one of the embodiments, described First idler wheel offers the first guide groove compatible with the cross section of first guide rail, so as not to the first idler wheel slip away it is first convex Platform slides the first idler wheel smoothly in first boss.In the present embodiment, the circular in cross-section shape of the first guide rail, makes First idler wheel is preferably rolled on the first guide rail.The second boss is equipped with the second guide rail in one of the embodiments, 213a, second idler wheel offer the second guide groove compatible with the cross section of second guide rail, in case the second idler wheel is sliding From second boss, slide the second idler wheel smoothly in second boss.In the present embodiment, the cross section of the second guide rail is in circle Shape rolls the second idler wheel preferably on the second guide rail.
As shown in fig. 6, the lying pipe falling film evaporator further includes pinch roller assembly 1100, institute in one of the embodiments, Pinch roller assembly is stated in the vaporizing body, and pinch roller assembly rolling is connected to the frame body, avoids frame sheet Body relative to there is the situation shaken in vaporizing body motion process, make frame body relative to first boss and second boss more Smoothly roll.
It is connected to chassis body to roll pinch roller assembly preferably, in one of the embodiments, the pinch roller assembly It is connected to the side away from first idler wheel of the chassis body, pinch roller assembly is rolled preferably and is connected to frame master Body.
As shown in fig. 6, the pinch roller assembly includes mounting base 1110 and the second idler wheel in one of the embodiments, 1120, the mounting base is set in the accommodating chamber and connect with the vaporizing body, is set to pinch roller assembly in vaporizing body, Second idler wheel is rotationally connected with the mounting base, and the second idler wheel rolling is connected to the frame body, makes press nips Part rolling is connected to frame body.Abuts that rigidity is excessive, and further, mounting base is slided to avoid pinch roller assembly and frame from rolling It is connected to vaporizing body.Pinch roller assembly further includes elastic component, and the both ends of elastic component connect with mounting base and vaporizing body respectively, make Mounting base is resiliently attached on vaporizing body.When frame has slight vibration during scrolling, frame passes through mounting base pressure Contracting elastic component, is extruded elastic component, and such pinch roller assembly can absorb rapidly slight vibration, to preferably avoid press nips It is excessive that the rolling of part and frame abuts rigidity.Further, mounting base is formed with T-type boss, and vaporizing body offers sliding slot, boss It is slidably connected in sliding slot and with vaporizing body, slides mounting base smoothly relative to vaporizing body.Since frame is slight Edge is absorbed perpendicular to rotating direction by elastic component when vibration, while frame absorbs the side of vibration relative to vaporizing body in elastic component There are light exercises upwards, move frame strip electric brush component in the telescopic direction of elastic component relative to heat exchanger tube, make hairbrush Component is other than with the movement of the direction of motion of frame, also with the direction of vibration light exercise of frame, to make brush member more The outer wall of brushing heat exchanger tube well further increases the scale removal effect of heat exchanger tube.
Transmission shaft is connected by shaft coupling in decelerating motor, the gear in rotation axis is under the driving of decelerating motor by torsion Rack gear is passed to, rack gear and frame are moved in a straight line, decelerating motor positive and negative rotation allows brush member to do reciprocating linear fortune It is dynamic, then encoder is controlled to determine the stroke moved back and forth every time by PLC control system.Brush member, which is fixed on frame, to be located at Between adjacent two heat exchanger tube of evaporator, reciprocal cleaning is done since hairbrush is not parked in heat exchange pipe surface, reaching prevents from exchanging heat The function of pipe surface fouling and scale removal.
Above-mentioned lying pipe falling film evaporator solves the problems, such as that heat exchanger tube is easy fouling and difficult scale removal, steams lying pipe falling liquid film Hair device more perfectly plays the advantage of system, enhances competitive advantage in industry, while saving using a large amount of soda acids Cleaning solution cleans the medicament expense of the tube wall of heat exchanger tube, and i.e. environmental protection can substantially reduce lying pipe falling film evaporator again on long terms Operating cost.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.
The several embodiments of the application above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously The limitation to claim therefore cannot be interpreted as.It should be pointed out that coming for those of ordinary skill in the art It says, without departing from the concept of this application, various modifications and improvements can be made, these belong to the protection of the application Range.Therefore, the scope of protection shall be subject to the appended claims by the application.
