Specific embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and accompanying drawing
It is bright.
Specific embodiment of the utility model as shown in Figure 1, Figure 2, Figure 3 shows, be by reducing motor 1, tube brush frame 8, tube brush 10,
Bracing frame 12, power transmission shaft 13 are constituted；Track 16 is respectively provided with two side walls of heat exchanger, the wheel 19 of bracing frame 12 is put
On track 16, tooth bar 7 is housed on bracing frame 12, bracing frame 12 is fixed together with tooth bar 7, and tooth bar 7 is walked with cleaning device
Gear 6 is engaged, and cleaning device walking gear 6 is fixed with power transmission shaft 13, power transmission shaft 13 run through whole heat exchanger, while with deceleration
Motor 1 connects, with tank body at sealed by axle sleeve 3, seal cover board 4, mechanical seal 5 and tank body, both sides respectively have the support of bearing 2 with
Reducing motor fixing device 17, follower ends fixing device 18 are fixed, and follower ends position limited gear 11, limit switch is housed in follower ends
Tooth bar 14 and limit switch 15, control the stroke of bracing frame 12, and tube brush frame 8, the bottom of tube brush frame 8 are fixed with interior shelf 12
There is tube brush fixing point 9, tube brush 10 is connected by joint with tube brush fixing point 9.
The side of power transmission shaft 13 is connected with reducing motor in fixing device 1, and opposite side is connected with follower ends in fixing device,
The gear driven on power transmission shaft 13 is rotated by reducing motor 1, so as to drive bracing frame 12.As shown in figure 4, in the middle of bracing frame 12
The side at position has high temperature resistant, high voltage bearing flexible pipe 20 to be connected with tank body, and tank body external flanges are connected with antisludging agent water pump.Support
The internal duct of frame 12 and the fixing point of hairbrush 23 all lead to, and the fixing point bottom of hairbrush 23 has loose joint 24 to fix with hairbrush 23, under loose joint 24
Respectively there is perforate portion pipe both sides, and antisludging agent, cleaning agent are sprayed onto on tube wall from showerhead hole 22, so as to alleviate fouling.
Several tube brush framves 8 are equidistantly housed, distance is the distance between tube sheet and pipe support on bracing frame 12.Tube brush frame 8 is wrapped
Include 2-8 groups.Between file of the tube brush 10 loaded on heat exchanger tube, the bristle of tube brush 10 is made up of high temperature resistant, wear resistant nylon.Power transmission shaft 13
Position through housing passes through mechanical seal.Two ends are equipped with limit switch on the guide rail of follower ends.The fixing point bottom hair of hairbrush 23
The pipe of brush 23 has showerhead hole 22, all connects to tube brush 10 inside bracing frame 12.
In installation process brush pipe device is positioned first, that is, the position and final position of starting, crossbeam uniformly divides
Cloth, the width between move distance i.e. tube sheet and pipe support.Because using gear reduced drive, not existing in transmission process and losing
Turn phenomenon, so, the number of turns of the distance correspondence rotation of reducing motor 1 of the movement of brush pipe.
