Description

Technical Field

[0001] The present application relates to the technical field of steam boiler cleaning, and in particular to a cleaning structure for a steam boiler. Background Art

[0002] A steam boiler is an energy conversion device. The energy input to the steam boiler is in the form of chemical energy in the fuel, electrical energy, high-temperature flue gas thermal energy, etc., and after conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy.

[0003] The scale cleaning device is a device used to clean the scale on the inner wall of the steam boiler. Its main function is to remove the scale and dirt on the inner wall of the boiler to ensure the normal operation and safety of the boiler. When cleaning the inner wall of the boiler, a steam boiler inner wall scale cleaning device is required. The existing cleaning device usually uses water flow to transmit to the inside of the boiler for cleaning using a brush during the cleaning process. Since the water flow that has not been properly treated after cleaning the boiler is discharged, the brush will wear out due to long-term use, resulting in a decrease in the cleaning effect.

[0004] Therefore, a cleaning structure for a steam boiler with improved cleaning effect is provided. Utility Model Content

The first rotating shaft 102 is rotatably connected to the boiler tank body 101. The guide rod 103 is radially slidably connected to the first rotating shaft 102. Specifically, the first rotating shaft 102 is provided with a first slide groove 102b extending radially along the first rotating shaft 102, and the guide rod 103 moves along the first slide groove 102b. The boiler tank body 101 includes a drain pipe 101a. The drain pipe 101a is provided with a valve for opening and closing the drain pipe 101a. The spray pipe 110 includes a water spray hole. A water inlet pipe is provided at one end of the spray pipe 110 . The water inlet pipe passes through the upper end of the boiler tank 101 and is communicated with the spray pipe 110 .

[0034] The cleaning brush 104 is fixedly connected to the guide rod 103. There are multiple cleaning brushes 104, which are equidistantly distributed along the circumferential direction of the first rotating shaft 102. The connecting plate 105 is fixedly connected to the first rotating shaft 102. The driving rod 106 is vertically slidably connected to the connecting plate 105. Specifically, the connecting plate 105 is provided with a second slide groove 105a extending along the height direction of the connecting plate 105, and the driving rod 106 moves along the second slide groove 105a. The screw 107 is threadedly connected to the first rotating shaft 102. The screw 107 includes a groove 107a, and the groove 107a is a hexagonal groove. The driving block 108 is fixedly connected to the driving rod 106. The transmission block 109 is fixedly connected to the guide rod 103.

[0035] The drive block 108 includes a first inclined surface 108a, and the transmission block 109 includes a second inclined surface 109a. The first inclined surface 108a abuts the second inclined surface 109a. The first rotating shaft 102 includes a first cavity 102a, and the drive rod 106 and the connecting plate 105 are both located in the first cavity 102a. The drive rod 106 includes a guide groove 106a, and the screw rod 107 is partially located in the guide groove 106a and rotates along the guide groove 106a. The hexagonal wrench is inserted into the groove 107a of the screw 107, and then the screw 107 is rotated, and the driving rod 106 moves along the second slide groove 105a, so the screw 107 drives the driving rod 106 to move along the second slide groove 105a through the guide groove 106a, and the driving rod 106 moves and drives the driving block 108 to move, and the driving block 108 drives the transmission block 109 to move through the first inclined surface 108a and the second inclined surface 109a, and the transmission block 109 moves and drives the guide rod 103 to move, and the guide rod 103 moves and drives the cleaning brush 104 to move, so that the cleaning brush 104 abuts against the inner wall of the boiler tank 101, preventing the cleaning brush 104 from being worn and causing the cleaning effect to decrease, thereby increasing the cleaning effect of the cleaning brush 104.

[0036] The drive assembly is used to rotate the first rotating shaft 102 and includes a motor 112, a first synchronous pulley 113, a second synchronous pulley 114, and a synchronous belt 115. The motor 112 is fixedly connected to the boiler tank 101. The first synchronous pulley 113 is fixedly connected to the drive shaft of the motor 112. The second synchronous pulley 114 is fixedly connected to the first rotating shaft 102. The ends of the synchronous belt 115 are respectively mounted on the first synchronous pulley 113 and the second synchronous pulley 114. The motor 112 drives the first synchronous pulley 113 to rotate. The first synchronous pulley 113 drives the second synchronous pulley 114 to rotate via the synchronous belt 115. The rotation of the second synchronous pulley 114 drives the first rotating shaft 102 to rotate. The rotation of the first rotating shaft 102 drives the guide rod 103 to rotate. The rotation of the guide rod 103 drives the cleaning brush 104 to clean the inner wall of the boiler tank 101.

[0037] Working process: The motor 112 drives the first synchronous wheel 113 to rotate, the first synchronous wheel 113 drives the second synchronous wheel 114 to rotate through the synchronous belt 115, the rotation of the second synchronous wheel 114 drives the first rotating shaft 102 to rotate, the rotation of the first rotating shaft 102 drives the guide rod 103 to rotate, the rotation of the guide rod 103 drives the cleaning brush 104 to rotate, thereby cleaning the inner wall of the boiler tank body 101, and at the same time, water cleans the scale of the boiler tank body 101 through the spray hole of the spray pipe 110 and is discharged from the drain pipe 101a. When the cleaning brush 104 is worn and the cleaning effect is reduced, the Allen wrench is inserted into the groove 107a of the screw 107, and then the screw 107 is rotated, and the drive rod 106 moves along the second slide groove 105a, so that the screw 107 drives the drive rod 106 to move along the second slide groove 105a through the guide groove 106a, and the drive rod 106 moves and drives the drive block 108 to move, and the drive block 108 drives the transmission block 109 to move through the first inclined surface 108a and the second inclined surface 109a, and the transmission block 109 moves and drives the guide rod 103 to move, and the guide rod 103 moves and drives the cleaning brush 104 to move, so that the cleaning brush 104 abuts against the inner wall of the boiler tank 101, preventing the cleaning brush 104 from being worn and causing the cleaning effect to be reduced, thereby increasing the cleaning effect of the cleaning brush 104.
