[0021] See also Figures 1 to 5 In this embodiment, a steam soot blower for a straw power generation boiler is provided, including a box body 1 and a blowing cavity 2. A cover plate is installed on the upper end surface of the box body 1 by threaded rotation, and the blowing cavity 2 is installed on the upper end surface of the cover plate. A plurality of air outlet holes 11 are opened on the outer wall of the blowing cavity 2 along its circumferential direction. An adjusting spring 12 is installed on the top of the blowing cavity 2, and an adjusting head 13 is installed on the bottom of the adjusting spring 12. An adjusting screw 14 is symmetrically installed on the upper end surface of the blowing cavity 2 by screw connection, and the adjusting screw 14 extends into the blowing cavity 2. A plurality of heating strips 15 are installed on the inner side wall of the box body 1 along its circumferential direction. A base is installed at the bottom of the box body 1, and a control panel 16 is installed on the front end surface of the base. When working, a PLC is programmed in the control panel 16. The program controls the operation of each device. Water is contained in the box 1, and the water is heated by the heating strip 15. The generated steam is arranged in the box 1. A valve is arranged on the outer wall of the blowing chamber 2. When the valve is opened, the steam enters the blowing chamber 2 and is discharged through the air outlet 11 to remove the ash from the boiler. When the steam enters the blowing chamber 2, the adjusting head 13 is driven to move upward, and the adjusting head 13 is pressed on the bottom of the adjusting screw 14. The adjusting head 13 is adjusted by rotating the upper and lower positions of the adjusting screw 14, so that part of the air outlet 11 can be shielded, and then the air outlet 11 can be adjusted according to the specifications of the boiler, so as to maximize the soot blowing effect of the steam and improve the convenience of using the device.

[0022] A top plate 17 is rotatably mounted on the upper end surface of the adjusting screw 14 through a bearing, a fixing seat 18 is symmetrically mounted on the outer side wall of the blowing cavity 2, an adjusting slider 19 is symmetrically mounted on the top plate 17, and the adjusting slider 19 is connected to the fixing seat 18 by sliding fit. When working, the top plate 17 structure is used to ensure the stability of the up and down movement of the adjusting screw 14 to avoid the adjustment screw 14 from deviating and causing locking.

[0023] A fixing hole is provided at the outer end of the fixing seat 18, and a T-shaped magnetic plate 21 is installed in the fixing hole by sliding fit. The outer end surface of the adjusting slider 19 is made of magnetic material. During operation, the T-shaped magnetic plate 21 and the adjusting slider 19 are attracted and fixed to prevent the adjusting slider 19 from moving up and down, thereby improving the overall stability of the device.

[0024] The front and rear end surfaces of the fixing seat 18 are symmetrically installed with connecting plates, and the connecting plates are connected to the T-shaped magnetic plate 21 through a reset spring 22. When working, the T-shaped magnetic plate 21 is pulled toward the outer end, so that the upper and lower positions of the adjustment slider 19 can be adjusted, and the reset spring 22 resets the T-shaped magnetic plate 21.

[0025] A column 23 is installed at the bottom of the box body 1 by threaded rotation, a water level sensor 24 is installed on the outer wall of the column 23, and an air pressure sensor 25 is arranged above the water level sensor 24. When working, the water level sensor 24 monitors the water level inside the box body 1, and the air pressure sensor 25 detects the air pressure inside the box body 1. The water level sensor 24 and the air pressure sensor 25 are both electrically connected to the control panel 16. The column 23 structure is adopted, so that by disassembling the column 23, it is convenient to take out the air pressure sensor 25 and the water level sensor 24 for inspection and maintenance.

[0026] An L-shaped plate 26 is symmetrically installed at the bottom of the box body 1. The L-shaped plate 26 is connected to the upper end surface of the column 23 by fixing bolts. When working, the L-shaped plate 26 limits and fixes the column 23 to prevent the column 23 from loosening, thereby improving the stability of the column 23.

[0027] During specific operation, a PLC program is written in the control panel 16 to control the operation of each device. Water is filled in the box 1, and the water is heated by the heating strip 15. The generated steam is arranged in the box 1. A valve is arranged on the outer wall of the blowing chamber 2. When the valve is opened, the steam enters the blowing chamber 2 and is discharged through the air outlet 11 to remove the ash from the boiler. In the process of the steam entering the blowing chamber 2, the adjusting head 13 is driven to move upward, and the adjusting head 13 is pressed on the bottom of the adjusting screw 14. The adjusting head 13 is adjusted by rotating the upper and lower positions of the adjusting screw 14, so that part of the air outlet 11 can be shielded, and then the air outlet 11 can be adjusted according to the specifications of the boiler, so as to maximize the soot blowing effect of the steam and improve the convenience of using the device.
