Abstract

The utility model relates to a scraper for scratching off sediments outside of a heat exchange tube, comprising a scraper that is installed outside of the cold (hot) coal tube of a heat exchanger, and a power device that is connected with the scraper. The scraper is composed of a framework that comprises upper-lower plates, and scraping rings that are sheathed outside of the heat exchanger tube. The power device comprises connecting rods, drive rods or chain wheels, link chains and a drive motor. The transmission device of the utility model is driven by the drive motor to make the framework and the scraping rings move vertically up and down corresponding to the heat exchanger tube, which achieves the purpose of scratching off the sediments outside of the tube and increases the effect of heat exchanging.

Description

Scraper for cutting scale on out wall of heat exchange tube
The utility model relates to a kind of servicing unit of heat exchanger, promptly a kind of heat-exchange tube external sediment thing removing device.
On the heat exchanger at present commonly used cold (heat) matchmaker to manage the deposit sweep-out method as follows: a kind of is that soup in the treatment trough is pumped to sending treatment trough again back to after heat-exchangers of the plate type is done heat exchange and used; therefore can produce deposit incrustation in pipeline and in the heat-exchangers of the plate type; influence heat exchanger effectiveness; must use aggressivity soup such as nitric acid to cleaning in the pipeline and in the heat-exchangers of the plate type like this; it is dangerous high; and poor effect; easy-clear is unclean yet for nitric acid in the pipeline; and the frequent shutdown operation detergent line system of operator, take a lot of work and time-consuming.Another kind method is hot coal to be pumped to treatment trough heat soup by the hot water in the heating tube row; the soup sprinkling is exclusive in pipe; its shortcoming is that deposit easily is deposited on pipe row and the trough rim; influence hot-swap feature; and deposit amasss at the bottom of treatment trough; need regularly to shut down with soup pump to storagetank to remove incrustation in the groove, make operation inconvenience.
The purpose of this utility model is to provide a kind of heat-exchange tube external sediment thing removing device for fear of the deficiency of above-mentioned prior art.It can make the continuous use of heat exchanger need not shut down, and can eliminate deposit automatically, has alleviated operating personnel's workload.
The purpose of this utility model is to realize by following measure: be used for the heat-exchange tube external sediment thing removing device of heat exchanger, be made of mud-scraping apparatus moving up and down and power set.Mud-scraping apparatus comprises the framework that lower plate constitutes and is enclosed within mud-scraping ring on the heat-exchange tube, mud-scraping ring also is contained between the lower plate, power set comprise connecting rod and drive rod, main follower and the CD-ROM drive motor that links to each other with framework, and power set also can drive chain, the sprocket transmission device of going up the framework both sides that lower plate constitutes by same motor and constitute.
Below by accompanying drawing the utility model is elaborated:
Fig. 1 is loaded on operation principle schematic diagram on the dislodger for this device;
Fig. 2 is the power set schematic diagram;
Fig. 3 is the right view of Fig. 2;
Fig. 4 is the mud-scraping apparatus schematic diagram;
Fig. 5 is chain, sprocket wheel actuating unit;
Fig. 6 is the power set schematic diagram of chain, sprocket wheel;
Fig. 7 is the left view of Fig. 6;
Fig. 8 is the vertical view of Fig. 3;
Fig. 9 is the vertical view of Fig. 6.
The utility model is outside the heat-exchange tube of heat exchanger, and promptly cold (heat) matchmaker manages one group of mud-scraping apparatus moving up and down of outer cartridge clip.This device comprises the framework that is made of upper and lower clamping plate 17,18 and is enclosed within mud-scraping ring 19 on the heat-exchange tube 20 that mud-scraping ring also is sandwiched in the groove that forms between the upper and lower clamping plate simultaneously.The framework that upper and lower clamping plate constitute is contained on four guide pillars 21,22,23,24 for four jiaos, and the upper and lower side of guide pillar is locked on the frame admittedly, and framework can move up and down by relative four guide pillars.Power set are that the both sides by framework are connected with connecting rod 15,16, and connecting rod links to each other with drive rod 13,14 again.Drive rod links to each other with the wheel shaft two ends of follower 12, and follower links to each other with CD-ROM drive motor 10 by driving wheel 11.Another embodiment of power set promptly adopts the transmission device of chain, sprocket-type as shown in Figure 5.The both sides of framework are linked to each other with chain 32 by brace 31, and chain overlaps respectively and is hung on the upper and lower sprocket wheel 33,34, and by same power motor 35 drive sprockets.
During use, soup, flow in the subsider 25 through heat-exchange tube 20 tops by the orifice flow on the runner pipe 26, does heat exchange by heat-exchange tube row in subsider.This device is installed outside heat-exchange tube, driving framework and mud-scraping ring by the motor drive link moves up and down to and fro at heat-exchange tube outer guide pillar, mud-scraping ring can will scrape and accumulate in bottom land attached to heat-exchange tube outer deposit 27 or crystallization, soup after the heating is deposited to bottom land through swash plate 28 with trickle suspension crystallization thing more once more, the soup of clarification is flowed back to by return duct 29 in the treatment trough of production line to be reused, deposit at the bottom of the subsider can be taken out pressure pipe 30 by deposition and regularly pump to the press type filter, or filter cloth formula filter filter deposition thing.
Adopt the utility model can effectively strike off the outer incrustation of heat-exchange tube; each mud-scraping ring is owing to be loaded between the upper and lower clamping plate; and framework move up and down can produce the trace unsteady adjustment position; can avoid the stuck situation of mud-scraping ring to take place; compare with medication water erosion descaling method; successful need not be shut down shut-down, and convenient operation has also improved operating efficiency.

Claims (2)

1, a kind of heat-exchange tube external sediment thing removing device, be mainly used in the heat-exchange tube of heat exchanger, its feature mainly is being made of mud-scraping apparatus moving up and down and power set, mud-scraping apparatus comprises the framework that lower plate constitutes and is enclosed within mud-scraping ring on the heat-exchange tube, mud-scraping ring also is contained between the lower plate simultaneously, framework is contained on the guide pillar for four jiaos, and the guide pillar upper and lower side is locked on the frame admittedly, and power set comprise connecting rod and drive rod, main follower and the CD-ROM drive motor that links to each other with framework.
2, removing device as claimed in claim 1 is characterized in that power set also can be driven chain that the framework both sides connect, sprocket transmission device and constituted by same motor.
