After all the water is discharged, the pump body 45 is closed, the threaded block 43 is unscrewed, and the impurities in the connecting box 42 are taken out, and the cleaning is completed.

[0030] Example 2

[0031] The present embodiment is different from the embodiment 1 in that: the drying processing device 7 comprises an air supply box 71, a heating cylinder 72, a heating wire 73, a fan 74 and an air outlet pipe 76; the air supply box 71 is installed between the wire block 6 and the nozzle driving assembly 8; the heating cylinder 72 is installed on the side of the air supply box 71 away from the connecting box 42; the fan 74 is installed on the side of the heating cylinder 72 away from the air supply box 71; a plurality of heating wires 73 are installed on the inner side of the heating cylinder 72; and two air outlet pipes 76 are installed on the air supply box 71 and below the heating cylinder 72.

[0032] By adopting the above technical solution, the device can cooperate with the fan 74 and the heating wire 73 to perform a certain drying process on the inside of the drying cylinder 1 when needed, so as to better meet the working needs in different situations.

[0033] Specifically, the drying device 7 further includes a filter screen 75 , and the filter screen 75 is installed on the side of the air inlet end of the fan 74 away from the heating cylinder 72 .

[0034] By adopting the above technical solution, the device can prevent foreign matter from entering the fan 74 through the filter 75, thereby reducing the possibility of damage to structures such as the fan 74 and the heating wire 73 due to foreign matter, and ensuring normal operation.

[0035] When this embodiment is used, when it is necessary to dry the inside of the drying cylinder 1, the fan 74 and the heating wires 73 in the drying device 7 are started. Under the action of the fan 74, the air enters the heating cylinder 72 after being filtered by the filter 75, and then the air is heated by the multiple heating wires 73. Then the hot air passes through the air supply box 71 and is ejected from the two air outlet pipes 76 to the inside of the drying cylinder 1, thereby drying the inside of the drying cylinder 1.

[0036] The structure and principle of the drying cylinder 1, the scraper assembly 2 consisting of a rotating roller, a telescopic sleeve, a telescopic rod, a scraper and a spring, the cleaning brush 3, the screw assembly 5 consisting of a cleaning bracket, a screw and a servo motor, the wire block 6, and the nozzle drive assembly 8 consisting of a sliding frame, a drive motor and a nozzle in the utility model have been disclosed in the cleaning device of the papermaking drying cylinder disclosed in Chinese patent application No. 202221502915.9. Its working principle is that when working, the operator first places the device on the top of the drying cylinder, so that the rotating roller enters the interior of the drying cylinder, and clamps it with a clamp under the push of a pressure spring. The drying cylinder quickly performs auxiliary limiting processing on the device, and then tightens the screw to limit and fix the slider, manually start the servo motor and drive motor, the drive motor drives the rotating roller to rotate, and drives the telescopic sleeve and the scraper to assist in cleaning the inner wall of the drying cylinder. The servo motor drives the screw to rotate, and the wire block drives the sliding frame to move back and forth horizontally, thereby improving the flexibility of the device. The spring can also push the telescopic rod to reduce the occurrence of dead corners for cleaning. At the same time, the water source is transported to the nozzle through an external water pump to spray and flush the inner wall of the drying cylinder. The structure is simple and easy to operate, the use is more flexible and efficient, and the cleaning effect is good.

[0037] The working principle and use process of the utility model are as follows: when the device is needed to clean the drying cylinder 1 for papermaking, the screw assembly 5 and other structures are placed on the drying cylinder 1, and the electric telescopic rods 461 in the two clamping assemblies 46 are started to drive the two clamping plates 462 to move, thereby driving the rubber extrusion block 463 to squeeze and fix the drying cylinder 1, and then the screw assembly 5 is started to adjust the positions of the wire block 6 and the nozzle drive assembly 8 and other structures, and the hose 47 is pulled out from the unclosed top of the connecting tube 41 in the self-draining clamping device 4 to make it leave the interior of the drying cylinder 1, and then the scraper assembly 2 and the cleaning brush 3 are driven to rotate through the nozzle drive assembly 8, and water is sprayed into the drying cylinder 1 to clean it. When the cleaning is completed, the nozzle drive assembly 8 is closed, and the hose 47 is sent into the interior of the drying cylinder 1. The pump body 45 is started. Under the action of the pump body 45, water and impurities therein pass through the hose 47 into the connection box 42, and then the water passes through the filter cloth 44 and the pump body 45 to be discharged, and the impurities are blocked by the filter cloth 44 and remain in the connection box 42. After all the water is discharged, the pump body 45 is closed, the threaded block 43 is unscrewed, and the impurities in the connection box 42 are taken out, and the cleaning is completed; when it is necessary to dry the inside of the drying cylinder 1, the fan 74 and each heating wire 73 in the drying treatment device 7 are started. Under the action of the fan 74, the air enters the heating cylinder 72 after being filtered by the filter screen 75, and then the air is heated by multiple heating wires 73, and then the hot air passes through the air delivery box 71 and is ejected from the two air outlet pipes 76 to the inside of the drying cylinder 1, thereby drying the inside of the drying cylinder 1.
