[0034] During specific use, when it is necessary to clean the heat exchange plate 11, first loosen the nuts on the plurality of limit screws 6 located on the front side of the fixed clamping plate 7, and then the staff pushes the sliding clamping plate 5 to slide backward on the base 1. When the pull rope 42 between the sliding clamping plate 5 and the connecting column 43 is kept tight, the sliding clamping plate 5 begins to drive the connecting column 43 to move synchronously. Similarly, the plurality of connecting columns 43 are pulled in turn to slide from front to back on the connecting slide plate 41, and the connecting column 43 drives the heat exchange plate 11 to move synchronously through the connecting slide plate 41.

[0037] like Figure 3 and Figure 4 As shown, the connecting member 21 includes a fixed slide rod 211 fixedly connected to the rear surface of the second slider 9, the rear end of the fixed slide rod 211 passes through the corresponding sliding clamp 5 and is slidably connected front and back, three equidistantly distributed installation sleeves 213 are slidably connected to the fixed slide rod 211, the upper surface of the installation sleeve 213 is fixedly connected to a connecting box 212, the three connecting boxes 212 are fixed and penetrated by connecting pipes, the upper surface of the front connecting box 212 is fixed and penetrated with an input pipe, the connecting box 212 is penetrated and connected to the corresponding water pipe rotating joint 236 through a connecting hose, the lower surface of the installation sleeve 213 is fixedly connected to two front-to-back symmetrical connecting vertical plates 214, the two connecting vertical plates 214 are rotatably connected to their corresponding connecting sleeves 235, and the connecting sleeves 235 under the three installing sleeves 213 rotate coaxially.

[0038] like Figure 5 As shown, the transmission member 24 includes a connection box 241 fixedly connected to the rear surface of the connection vertical plate 214 on the rearmost side, and four elastic telescopic limit seats 243 are fixedly connected in a circular array on the rear inner wall of the connection box 241. The rear end of the elastic telescopic limit seat 243 is provided with a snap-in ball. The interior of the connection box 241 is rotatably connected to two upper and lower distributed pulleys 242, and the two pulleys 242 are driven by a belt. The front end of the bottom pulley 242 passes through the outside of the connection box 241 and is fixedly connected to the corresponding connection sleeve 235.

[0039] like Figure 5As shown, the adjusting member 22 includes a turntable 227 rotatably connected to the rear surface of the connecting box 241, the rear end of the pulley 242 penetrates the outside of the connecting box 241 and is fixedly connected to the front surface of the turntable 227, the front surface of the turntable 227 is provided with four limiting holes corresponding to four elastic telescopic limiting seats 243, the size of the limiting holes is adapted to the size of the clamping ball on the elastic telescopic limiting seat 243, the rear surface of the turntable 227 is fixedly connected with a mounting sleeve 224 at the center position of the circle, and the mounting sleeve 224 is fixedly connected to the rear surface of the turntable 227. The sleeve 224 is internally connected to a connecting slide rod 225 for forward and backward sliding movement, a return spring is arranged between the mounting sleeve 224 and the connecting slide rod 225, two upper and lower symmetrical limit columns 226 are fixedly connected to the rear inner wall of the mounting sleeve 224, a push plate 222 is fixedly connected to the rear end of the connecting slide rod 225, four push rods 223 corresponding to four elastic telescopic limit seats 243 are evenly distributed on the front surface of the push plate 222, and a rotating ring 221 is fixedly connected to the circumferential surface of the turntable 227.

[0040] In actual use, after all the heat exchange plates 11 are evenly dispersed, first adjust the positions of the three installation sleeves 213 on the right side so that the installation sleeve 213 on the front side is located at the frontmost side of the fixed slide rod 211, and then press the push plate 222. At this time, the push plate 222 pushes the connecting slide rod 225 to slide toward the inside of the installation sleeve 224 to compress the return spring. When the front end of the connecting slide rod 225 is attached to the rear end of the limit column 226, the push plate 222 stops moving, and the push rod 223 pushes the elastic telescopic limit seat 243 to compress, and the card receiving ball at the rear end of the elastic telescopic limit seat 243 is removed from the turntable 2 The push rod 223 is pushed out from the limiting hole on the upper end of the turntable 227 and the front end of the push rod 223 is kept flush with the front surface of the turntable 227. At this time, the elastic telescopic limiting seat 243 no longer limits the turntable 227, and the turntable 227 is driven to rotate on the connecting box 241 by rotating the rotating ring 221. At the same time, the thrust on the push plate 222 is cancelled, and the push plate 222 is restored to its original position under the action of the elastic force of the reset spring. At this time, the push rod 223 is disengaged from the limiting hole at the upper end of the turntable 227, and the upper pulley 242 rotates synchronously with the turntable 227 and drives the connecting sleeve 235 to rotate on the connecting vertical plate 214 through the lower pulley 242.

[0041] When the turntable 227 rotates ninety degrees, the elastic telescopic limit seat 243 is no longer subjected to the thrust of the push rod 223, and the elastic telescopic limit seat 243 is re-engaged in the limit hole on the turntable 227. At this time, the cleaning pipe 231 changes from a vertical state to a horizontal state, and extends between the two heat exchange plates 11. The frontmost cleaning pipe 231 is positioned between the fixed clamp 7 and the heat exchange plate 11. At the same time, the adjustment method of the cleaning pipe 231 on the left is the same as above. After all the states of the cleaning pipes 231 are adjusted, the cleaning work of the heat exchange plate 11 begins.

[0042] At this time, the external cleaning liquid delivery pipe is connected to the connecting pipe on the frontmost connecting box 212, and the cleaning liquid enters the connecting box 212 and is transported to the other two connecting boxes 212 through the connecting pipe. The cleaning liquid inside the connecting box 212 is transported to the inside of the cleaning pipe 231 through the connecting hose and the cleaning brush 232, and is sprayed on the heat exchange plate 11 from the spray holes on the circumferential surface of the cleaning pipe 231 to clean the heat exchange plate 11.

[0043] like Figure 6 As shown, the auxiliary mechanism 8 includes an auxiliary member 82 which is commonly provided on the first slider 3 and the second slider 9 at the front side, and a linkage member 81 is provided at the front end of the auxiliary member 82 .

[0044] like Figure 6 and Figure 7 As shown, taking the auxiliary part 82 on the right side as an example, the auxiliary part 82 includes a mounting frame 821 fixedly connected to the right side of the second slider 9, a connecting support plate 823 is fixedly connected to the right side of the first slider 3, a snap-in sleeve 824 is fixedly connected to the right side of the connecting support plate 823, a limiting strip 822 is connected to the mounting frame 821 and the snap-in sleeve 824 for forward and backward sliding connection, a transmission unit 825 is arranged on the left side of the limiting strip 822, a plurality of slots are evenly arranged on the transmission unit 825, and the size of the slots is adapted to the size of the teeth of the cleaning brush 232.

[0045] like Figure 6 and Figure 7 As shown, taking the linkage member 81 on the right side as an example, the linkage member 81 includes a tooth plate 813 fixedly connected to the front surface of the fixed clamp 7, a mounting seat 812 is fixedly connected to the front surface of the second slider 9, a second gear 811 is rotatably connected to the mounting seat 812, the left end of the second gear 811 is meshed with the tooth plate 813, and the right end of the second gear 811 is rotatably connected to the transmission unit 825.

[0046] During specific use, when the cleaning pipe 231 becomes horizontal, the cleaning pipe 231 on one side flips over the half of the side of the heat exchange plate 11. At this time, the first gear 233 on the cleaning pipe 231 is in contact with the upper surface of the transmission unit 825. As the staff starts to clean the heat exchange plate 11, the staff pulls the fixed slide bar 211 up and down to drive the cleaning pipe 231 to move up and down to clean the heat exchange plate 11. At this time, the fixed slide bar 211 drives the second slide bar 9 to move synchronously, and the second slide bar 9 drives the transmission unit 825 to move synchronously with the cleaning pipe 231. In the process of the second slide bar 9 moving up and down, the second gear 811 is in contact with the tooth plate 81. 3 slides up and down, at this time, the second gear 811 rotates on the mounting seat 812, and drives the transmission unit 825 to rotate synchronously. At this time, the transmission unit 825 drives the cleaning pipe 231 to rotate on the connecting sleeve 235 through the first gear 233, and the setting of the water pipe rotating joint 236 ensures the normal transportation of the cleaning liquid during the rotation of the cleaning pipe 231. At this time, the cleaning pipe 231 rotates synchronously during the up and down movement, and the side of the heat exchange plate 11 is cleaned by the cleaning brush 232 to clean the dirt attached to the heat exchange plate 11. At the same time, the dirt on the heat exchange plate 11 can be cleaned more thoroughly by spraying the cleaning liquid and cleaning with the cleaning brush 232.

[0047] After the four heat exchange plates 11 are cleaned once, the cleaning pipe 231 is readjusted to a vertical state through the adjusting member 22, and then the cleaning sleeve 213 is installed to slide backward on the fixed slide rod 211 to push the cleaning pipe 231 to the position of the next four uncleaned heat exchange plates 11, and then the cleaning pipe 231 is readjusted to a horizontal state to clean the heat exchange plates 11. At the same time, the cleaning pipe 231 on the other side of the heat exchange plate 11 is also cleaned in the same way as the above steps. All the heat exchange plates 11 can be cleaned by repeating the above steps. When all the heat exchange plates 11 are cleaned, the multiple heat exchange plates 11 are restored to their original positions by screwing the nut on the limit screw 6 located on the front side of the fixed clamp 7, and then the equipment continues to perform normal heat exchange work.

[0048] Working principle: During specific use, when the heat exchange plate 11 needs to be cleaned, first loosen the nuts on the multiple limit screws 6 located on the front side of the fixed clamp 7, and then the staff pushes the sliding clamp 5 to slide backward on the base 1, and the heat exchange plates 11 between the two limit cross bars 10 are equidistantly dispersed through the equidistant dispersion mechanism 4, and then the nut on the limit screw 6 located on the rear side of the fixed clamp 7 is turned close to the rear surface of the fixed clamp 7. At this time, the multiple heat exchange plates 11 remain in an equidistantly dispersed state, and then the cleaning pipe 231 is adjusted from vertical to horizontal through the adjusting member 22. At this time, the cleaning pipe 231 extends between the two heat exchange plates 11.

[0049] Then, by connecting the external cleaning liquid delivery pipe to the connecting box 212, the staff pulls the fixed slide bar 211 up and down to start cleaning the heat exchange plate 11. While the fixed slide bar 211 moves up and down, the auxiliary mechanism 8 drives the cleaning pipe 231 to rotate on the connecting sleeve 235 through the first gear 233, and drives the cleaning brush 232 to rotate to clean the dirt attached to the upper surface of the heat exchange plate 11. At the same time, the spray holes on the cleaning pipe 231 and the cleaning liquid sprayed out are coordinated to perform synchronous cleaning. When the cleaning is completed, the cleaning pipe 231 is readjusted to a vertical state through the adjusting member 22. Then, the sliding sleeve 213 is installed to slide backward on the fixed sliding rod 211, and the cleaning pipe 231 is pushed to the position of the uncleaned heat exchange plate 11. Then, the cleaning pipe 231 is readjusted to a horizontal state to clean the heat exchange plate 11. At the same time, the cleaning pipe 231 on the other side of the heat exchange plate 11 is also cleaned in the same way as the above steps. The above steps can be repeated to clean all the heat exchange plates 11.
