[0008] Furthermore, the air hammer includes a cylinder, a piston, a plug and a hammer head. The lower surface of the cylinder is fixedly connected to the upper surface of the adjacent fixed frame. The interior of the cylinder is slidably connected to the piston. The lower surface of the piston is provided with a plug. The lower end of the plug passes through the bottom wall of the cylinder and is provided with a hammer head. The hammer head corresponds to the vertically adjacent filter cartridge head cover, which is convenient for hammering and cleaning.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the hammer-type dust cleaning device has the following advantages:

[0014] 1. When the reversing solenoid valve is in the forward direction, compressed air enters from the lower pipe joint of the air hammer to drive the piston to move upward, and exhausts from the upper pipe joint, so that the hammer head returns to the initial position. When the reversing solenoid valve is in the reverse direction, compressed air enters the cylinder from the upper pipe joint of the air hammer to drive the piston to move downward, and exhausts from the lower pipe joint. The hammer head is driven by the plug to hammer on the filter cartridge head cover, performing hammer-type cleaning, reducing costs and reducing maintenance work.

[0015] 2. The air intake and exhaust of the cylinder are controlled by the reversing solenoid valve, and the gas pressure delivered by the compressed air pipe is adjusted by the pressure reducing regulating valve. The number and intensity of the hammering of each air hammer can be adjusted to solve the problem of uneven airflow in pulse cleaning.

[0016] 3. The rotation of the screw drives the bracket slide to move along the slide rail, causing the air hammer to move accordingly. Due to the presence of the slide rail and rubber elastic parts, the bracket slide can move smoothly to the top of the filter cartridge for hammering and cleaning, and can support and buffer the load force generated by the air hammer when it is working.

[0017] 4. Through the limit port set on the gantry bracket just above the filter cartridge, the bracket slide can sense the limit port and move accurately to the top of the corresponding filter cartridge to hammer and clean the filter cartridge. The filter cartridge can be hammered accurately to solve the problem of difficult alignment of the pulse cleaning blowpipe nozzle.

[0018] 5. The hammer head is an elastic rubber hammer head. When the hammer head reciprocates and hammers the filter cartridge head cover under the action of the piston, the elastic rubber hammer head can increase the vibration amplitude, vibrate and separate the dust attached to the filter material of the filter cartridge, and clean the dust efficiently. In addition, the elastic rubber hammer head can buffer the force on the filter cartridge head cover and extend the service life of the filter element. BRIEF DESCRIPTION OF THE DRAWINGS

The air hammer 7 includes a cylinder 71, a piston 72, a plug 73 and a hammer head 74. The lower surface of the cylinder 71 is fixedly connected to the upper surface of the adjacent fixed frame 6, and the interior of the cylinder 71 is slidably connected to the piston 72. The lower surface of the piston 72 is provided with a plug 73, and the lower end of the plug 73 passes through the bottom wall of the cylinder 71 and is provided with a hammer head 74. The hammer head 74 corresponds to the vertically adjacent filter cartridge head cover 10 (the hammer head 74 is an elastic rubber hammer head). The air hammer 7 also includes an upper pipe joint 75, an upper air hole 76, a lower pipe joint 77 and a lower The top wall of the cylinder 71 is provided with an upper air hole 76, and the upper end of the outer surface of the cylinder 71 is provided with an upper pipe joint 75. The upper pipe joint 75 is connected to the interior of the cylinder 71 through the upper air hole 76. The bottom wall of the cylinder 71 is provided with a lower air hole 78. The lower end of the outer surface of the cylinder 71 is provided with a lower pipe joint 77. The lower pipe joint 77 is connected to the interior of the cylinder 71 through the lower air hole 78. (The upper pipe joint 75 and the lower pipe joint 77 on the cylinder 71 are respectively connected to the air distribution port of the reversing solenoid valve switch through the upper air inlet pipe and the lower air inlet pipe, and the air inlet of the reversing solenoid valve is connected to the pressure reducing regulating valve through the compressed air pipe). The outer surface of the filter cartridge head cover 10 is provided with a sealing ring 12. The outer surface of the sealing ring 12 contacts the inner wall of the flower plate hole 9. A limit opening 13 is provided on the left side of the door bracket 1. The limit openings 13 are all located above the vertically adjacent filter cartridges 11. A lifting valve 14 is provided on the rear side of the upper surface of the gantry bracket 1. When dust cleaning is required, the staff turns on the motor 5 through the external controller. The output shaft of the motor 5 drives the screw 2 to rotate. The rotation of the screw 2 drives the threaded bracket slide 3 to move along the slide rail 4, causing the air hammer 7 to move along. When the bracket slide 3 moves to the position of the limit opening 13, it stops. At this time, the air hammer 7 corresponds to the vertically adjacent filter cartridge 11, and then the reversing solenoid valve and the pressure reducing regulating valve are opened. When the reversing solenoid valve is in the forward direction, the compressed air is taken in from the lower pipe joint 77 of the air hammer 7 to drive the piston 72 to move upward, and the upper pipe joint 75 is exhausted, so that the hammer head 74 returns to the initial position.When the reversing solenoid valve is in the reverse direction, compressed air enters the cylinder 71 from the upper pipe joint 75 of the air hammer 7, driving the piston 72 to move downward, and the lower pipe joint 77 is exhausted.

The elastic rubber hammer head can also buffer the force acting on the filter cartridge head cover 10, extending the service life of the filter cartridge 11. The lifting valve 14 isolates the filter cartridge chamber that needs to be cleaned from the filter cartridge chamber that is working, thereby avoiding the influence of the external environment on the cleaning work.

[0027] The working principle of a hammering type dust cleaning device provided by the present invention is as follows: when dust cleaning work is required, the staff turns on the motor 5 through the external controller, and the output shaft of the motor 5 drives the screw 2 to rotate. The rotation of the screw 2 drives the threaded support slide 3 to move along the slide rail 4, causing the air hammer 7 to move accordingly. When the support slide 3 moves to the position of the limit port 13 and stops, the air hammer 7 corresponds to the vertically adjacent filter cartridge 11, and then the reversing solenoid valve and the pressure reducing regulating valve are opened. When the reversing solenoid valve is in the forward direction, compressed air is taken in from the lower pipe joint 77 of the air hammer 7, driving the piston 72 to move upward, and the upper pipe joint 75 is exhausted, so that the hammer head 74 reaches the initial position. When the reversing solenoid valve is in the reverse direction, compressed air is taken in from the upper pipe joint 77 of the air hammer 7, driving the piston 72 to move upward, and the upper pipe joint 75 is exhausted, so that the hammer head 74 reaches the initial position. The joint 75 enters the cylinder 71 to drive the piston 72 to move downward, the lower pipe joint 77 is exhausted, and the hammer head 74 is driven by the plug 73 to hammer on the filter cartridge head cover 10, completing one action to hammer and clean the filter cartridge. The air intake and exhaust of the cylinder 71 are controlled by the reversing solenoid valve, and the gas pressure delivered by the compressed air pipe is adjusted by the pressure reducing regulating valve. The hammer head 74 is an elastic rubber hammer head, which can increase the vibration amplitude, vibrate and separate the dust attached to the filter material of the filter cartridge 11, and clean the dust efficiently. The elastic rubber hammer head can buffer the force on the filter cartridge head cover 10, thereby extending the service life of the filter cartridge 11. The lifting valve 14 isolates the filter cartridge chamber that needs to be cleaned from the filter cartridge chamber that is working, thereby avoiding the influence of the external environment on the cleaning work.
