The vertical position of the top mounting shaft 51 is limited by the first nut 70, and the height position of the top pressure wheel 50 is adjusted, which has the advantages of simple structure and convenient adjustment operation.

[0037] In this embodiment, the bottom guide wheel 20 includes a bottom mounting shaft 21 and a bottom wheel body 22 rotatably mounted on the bottom mounting shaft 21, and the two ends of the bottom mounting shaft 21 are respectively mounted on two screws 60, and the side guide wheel 30 includes a side mounting shaft 31 and a side wheel body 32 rotatably mounted on the side mounting shaft 31, and the screw 60 is passed through the side mounting shaft 31 and is coaxially arranged with the side mounting shaft 31, and the lower end of the side mounting shaft 31 abuts against the bottom mounting shaft 21, and the screw 60 is provided with a second nut 80 abutting against the upper end of the side mounting shaft 31. With the above structure, the bottom guide wheel 20, the side guide wheel 30 and the top pressure wheel 50 are all fixed on the screw 60, which has the advantages of convenient assembly on the one hand, and can improve the compactness of the assembly of the components on the other hand.

[0038] like Figure 1 and Figure 2 As shown, the storage device of the drying tower cleaning parts also includes two spacer sleeves 90, which are respectively sleeved on the two screws 60, the lower ends of the spacer sleeves 90 are in contact with the frame 10, and the bottom mounting shaft 21 is sandwiched between the upper end of the spacer sleeve 90 and the lower end of the side mounting shaft 31. The spacer sleeves 90 can be used to prop up the bottom mounting shaft 21, provide a rotation space for the bottom wheel body 22, and realize the assembly of the bottom guide wheel 20 and the side guide wheel 30.

[0039] In this embodiment, the spacer sleeve is made of a round sleeve with a diameter of 25 mm and a height of 40 mm.

[0040] In this embodiment, the top pressure wheel 50 further includes a top bearing, and the top wheel body 52 is sleeved on the top mounting shaft 51 through the top bearing, the bottom guide wheel 20 further includes a bottom bearing, and the bottom wheel body 22 is sleeved on the bottom mounting shaft 21 through the bottom bearing, and the side guide wheel 30 further includes a side bearing, and the side wheel body 32 is sleeved on the side mounting shaft 31 through the side bearing.

[0041] Specifically, the bottom wheel body 22 uses a round roller with a diameter of 55 mm and a length of 150 mm. Both ends of the roller are mounted on the bottom mounting shaft 21 through 205 bearings and fixed by retaining springs. The two side wheel bodies 32 use round rollers with a diameter of 55 mm and a height of 60 mm. Both ends of the rollers are mounted on the side mounting shaft 31 through 205 bearings and fixed by retaining springs. The top wheel body 52 uses a round roller with a diameter of 55 mm and a length of 150 mm.

[0042] like Figure 1 and Figure 4 As shown, the frame 10 includes a first plate 12 and a second plate 13 arranged in a transverse direction, the extension direction of the first plate 12 is perpendicular to the extension direction of the second plate 13, one end of the first plate 12 is connected to the middle of the second plate 13, the drying tower connection part 11 is arranged at the end of the first plate 12 away from the second plate 13, and the bottom guide wheel 20, the two side guide wheels 30 and the top pressure wheel 50 are all arranged on the second plate 13. The frame 10 has the advantages of simple structure and low cost. Since the bottom guide wheel 20, the two side guide wheels 30 and the top pressure wheel 50 are located on the second plate 13 at one end of the first plate 12, and the drying tower connection part 11 is located at the other end of the first plate 12, the bottom guide wheel 20, the two side guide wheels 30 and the top pressure wheel 50 can be extended into the tower as much as possible, which is convenient for the placement or recovery of the cleaning pipe.

[0043] In this embodiment, the first plate body 12 and the second plate body 13 are both steel plates, and the first plate body 12 and the second plate body 13 are welded together, which is easy to process and has low cost.

[0044] like Figure 1 and Figure 4 As shown, the drying tower connection part 11 includes a bolt connection hole 111. The bolts are passed through the bolt connection hole 111 and connected to the drying tower, so that the storage device of the drying tower cleaning parts can be fixed. In this embodiment, the frame can be fixed to the edge of the tower top.

[0045] Specifically, the frame 10 is a T-shaped frame, which is welded from 10 mm thick white steel plates. The length of the second plate body 13 is 200 mm, the length of the first plate body 12 is 260 mm, and the diameter of the bolt connection hole 111 is 12 mm.

[0046] In the related art (comparative example), a cross-spray cleaning device is placed in the drying tower every time the tower is brushed and cleaned. Since this device needs to be connected to a cleaning pipe externally, and the cleaning pipe is a rubber hose, it is very laborious for personnel to put the rubber hose into the tower, and the speed of putting the cleaning pipe in cannot be effectively controlled, which will also cause certain dangers. In this embodiment, four rollers (bottom guide wheel 20, two side guide wheels 30 and top pressure wheel 50) are installed on a three-angle frame (frame 10). The frame can be fixed to the edge of the tower top and fixed with screws. When the cleaning pipe is placed in the tower, the cleaning pipe will move along the lowest pulley. The pulleys on both sides play a guiding role. The upper pulley can be adjusted up and down to clamp the pipe, and the pipe is slowly moved down at a uniform speed depending on the degree of clamping.

[0047] The device provided by this embodiment has the following beneficial effects:

[0048] (1) The cross spray cleaning device can be effectively placed into the tower slowly and ensure that no foreign matter is generated;

[0049] (2) After installing this device, the risk level of personnel is effectively reduced, time and effort can be saved, and product quality problems caused by foreign matter entering the tower can be prevented.
