An arrow is marked on the positioning rod 508, and a scale mark is marked on the corresponding indicating rod 506.
Example 1:
taking the example that 5 pairs of protrusions 50111 are disposed in the sliding rails 5011 of the involute circulation valve 5 and the involute circulation valve 12, the corresponding spoiler 501 has five stopping positions, so that there are airflow passage areas of five gears between the spoiler 501 and the first valve housing 5091 or the second valve housing 5092, that is, there are five opening degrees of the involute circulation valve 5 and the involute circulation valve 12. The gear positions are defined by the opening degrees of the involute circulation valve 5 and the involute circulation valve 12, and the opening degrees are sequentially from small to large, namely, from first gear to fifth gear.
In the present embodiment, the involute circulation valve 5 is set to the first gear, and the involute circulation valve 12 is set to the fifth gear.
When the first dust remover is used for cleaning the filter cartridge, the pulse controller 8 controls the top pulse valve 7 and the bottom pulse valve 11 to be opened simultaneously, compressed air in the air bag 9 reaches the involute circulating valve 5 through the top pulse valve 7 and the top blowing pipe 4, and simultaneously, compressed air in the air bag 9 reaches the involute circulating valve 12 through the bottom pulse valve 11 and the bottom blowing pipe 13. Since the involute circulation valve 5 is in the first gear position, the upper outlet pressures, denoted as P1 to P5, increase in sequence as the airflow passes through the involute circulation valve to the top nozzle 3. With the setting of the involute valve 12 in fifth gear, the lower outlet pressure is designated as P5 when the air flow passes through involute valve 12 to bottom nozzle 15. The forced impingement of the blowing air streams into the cartridge 14 causes the dynamic pressure of the blowing air streams to be converted into static pressure which can generate ash removal force on the side wall of the cartridge 14 due to the outlet pressure difference between the P1 and the P5, so that the upper area of the cartridge 14 is subjected to energy-concentrated ash removal.
Meanwhile, under the impact of the airflow, the flow blocking plates 501 in the involute circulation valve 5 and the involute circulation valve 12 are both forced to move downwards, so that the second spring 5032 arranged in the elastic slider 5031 contracts and passes through a clamping protrusion 50111, and then the flow blocking plates 501 stop at the next gear position, namely, the involute circulation valve 5 enters the second gear position and the involute circulation valve 12 enters the fourth gear position.
In the second ash removal, the outlet pressure is P2 after the airflow reaches the top nozzle 3 through the top involute circulation valve 5 because the involute circulation valve 5 is in the second gear position. Since the involute valve 12 is in fourth gear, the outlet pressure is P4 after the air flow passes through involute valve 12 to bottom nozzle 15. The upper middle region of the cartridge 14 is subjected to energy intensive ash removal due to the intense impingement of the blowing air streams on the upper middle portion of the cartridge 14 caused by the outlet pressure differential between P2 and P4.
Meanwhile, under the impact of the airflow, the spoilers 501 in the involute circulating valve 5 and the involute circulating valve 12 are forced to move downward and stop at the next gear position, that is, the involute circulating valve 5 enters the third gear position, and the involute circulating valve 12 enters the third gear position.
In the third ash removal, the involute circulating valve 5 is in the third gear position, and the outlet pressure of the airflow reaches the top nozzle 3 through the involute circulating valve 5 at the top, and is P3. Since the involute valve 12 is in third gear, the outlet pressure is P3 after the air flow passes through involute valve 12 to bottom nozzle 15. Since the outlet pressure difference is 0, the blowing air flow collides violently at the center of the filter cartridge 14, and the central area of the filter cartridge 14 is subjected to the energy-concentrated soot cleaning action.
Meanwhile, under the impact of the airflow, the spoilers 501 in the involute circulating valve 5 and the involute circulating valve 12 are forced to move downward and stop at the next gear position, that is, the involute circulating valve 5 enters the fourth gear position, and the involute circulating valve 12 enters the second gear position.
In the fourth ash removal, the outlet pressure is P4 after the airflow reaches the top nozzle 3 through the top involute circulation valve 5 because the involute circulation valve 5 is in the fourth gear position. Since the involute valve 12 is in second gear, the outlet pressure is P2 after the air flow passes through involute valve 12 to bottom nozzle 15. The lower middle region of the cartridge 14 is subjected to energy intensive ash removal due to the intense impingement of the blowing air streams on the lower middle portion of the cartridge 14 caused by the outlet pressure differential between P4 and P2.
Meanwhile, under the impact of the airflow, the spoilers 501 in the involute circulating valve 5 and the involute circulating valve 12 are forced to move downward and stop at the next gear position, that is, the involute circulating valve 5 enters the fifth gear position, and the involute circulating valve 12 enters the first gear position.
In the fifth ash removal, since the involute circulation valve 5 is in the fifth gear position, the outlet pressure of the airflow reaches the top nozzle 3 through the top involute circulation valve 5 is P5. Since the involute valve 12 is in the first gear, the outlet pressure is P1 after the air flow passes through involute valve 12 to bottom nozzle 15. The upper region of the cartridge 14 is subjected to energy intensive ash removal due to the intense impingement of the blowing air streams on the upper portion of the cartridge 14 caused by the outlet pressure differential between P5 and P1.
Thus, the ash removing process with concentrated energy is realized in the upper, middle and upper, middle and lower areas in the filter cylinder 14.
Meanwhile, under the impact of the airflow, the spoiler 501 of the involute circulation valve 5 is forced to move downwards, so that the impact rod 502 fixed on the spoiler 501 impacts the reset valve 510, the reset valve 510 is pressed down, the through hole 5013 enters the position between the sleeve 505 and the top bleed air pipe 6 to enable the sleeve 505 and the top bleed air pipe 6 to be communicated, and the sleeve 505 and the air release opening 511 are separated due to the existence of the reset valve 510. At this time, the compressed air in the air bag 9 flows through the top bleed air pipe 6 and enters the sleeve 505 through the through hole 5013, and the reset rod 504 in the sleeve 505 continues to move upward under the action of the compressed air flow, and drives the spoiler 501, the striker 502 and the slide rod 503 to move until reset.
In the process that the spring I5101 arranged on the reset valve 510 drives the reset valve 510 to reset, the reset process of the reset valve 510 is slower and later than the reset of the spoiler 501 due to the damping effect of the stretching damper 5102. After the reset valve 510 is reset, the through hole 5013 is separated from the position between the sleeve 505 and the top bleed air pipe 6 to block the sleeve 505 and the top bleed air pipe 6, the compressed air in the air bag 9 does not enter the sleeve 505 any more, and the sleeve 505 and the air release opening 511 are not blocked by the reset valve 510 to be conducted, and the compressed air stored in the sleeve 505 is released through the release opening 511. Similarly, the involute valve 12 is repositioned in the same manner and configuration.
At this point, the resetting of the involute circulation valve 5 and the involute circulation valve 12 is completed, and the cycle period of one round is finished.
In the above process, the positioning rod 505 is driven to extend or retract from the valve housing 509 by the movement of the sliding rod 503, and the scale positions on the indicating rod 506 corresponding to the arrow on the positioning rod 505 are read to obtain the gear positions of the involute circulation valve 5 and the involute circulation valve 12.
Example 2:
when the filter cartridge 14 needs to be cleaned by the impinging air flow with continuous energy concentration locally, the position of the positioning rod 508 can be adjusted manually and the positioning screw 507 is screwed to fix the position of the positioning rod 508, at this time, the sliding rod 503 is fixed by the positioning rod 508, so that the spoiler 501 cannot move, the gears of the involute circulating valve 5 and the involute circulating valve 12 are not changed even under the impact of the pulse air flow, and further, the opening degree is kept unchanged to maintain the stable outlet pressure.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent modifications made by the present invention and the contents of the drawings or directly or indirectly applied to the related technical fields are included in the scope of the present invention.
