[0019] The present invention will be further described below in conjunction with specific examples and accompanying drawings.

[0020] like Figure 1-Figure 4As shown, a fully intelligent dust removal unit includes two dust removal tanks 1, each of which is divided into: a lower dust collecting hopper 11, a middle filtering area 12, and an upper cleaning area 13; a partition 2 is installed between the middle filtering area 12 and the upper cleaning area 13 in each dust removal tank 1, and the partition 2 is provided with a plurality of filter mounting holes 201, and a plurality of dust filters 3 are installed downward at each filter mounting hole 201; the top of the dust removal tank 1 The flange top cover 8 is connected to the middle of the two dust removal tank bodies 1; the outer sides of the middle filter area 12 of the two dust removal tank bodies 1 are respectively connected to the air inlet pipe 101 and the air inlet valve 102, and the outer sides of the upper cleaning area 13 of the two dust removal tank bodies 1 are respectively connected to the air outlet pipe 103 and the air outlet valve 104, the air inlet pipe 101 of the two dust removal tank bodies 1 is connected to the three-way air inlet pipe 105, and the air outlet pipe 103 of the two dust removal tank bodies 1 is connected to the three-way air outlet pipe 106, that is, the two dust removal tank bodies 1 are connected in parallel;

[0021] The connection between the air inlet duct 101 and the tank body is located at the junction of the filter area 12 and the dust collecting hopper 11, and the connection between the air outlet duct 103 and the tank body is located at the upper cleaning area 13 and the outer side of the two dust removal tank bodies 1; wherein: a plurality of pulse air pipes 4 penetrating into the upper cleaning area 13 and the outer side of the two dust removal tank bodies 1 are provided on the outer wall of the upper cleaning area 13 of the dust removal tank body 1, and a pulse valve 41 is installed in each pulse air pipe 4, and the inner end of each pulse air pipe 4 is downwardly opposite to the air outlet end of one of the dust filters 3, and the outer end of each pulse air pipe 4 is connected to the back-blowing air inlet pipe 42 arranged on the outside of the tank body, and the back The air supply interface 420 of the blowing air intake pipe 42 is located in the middle; the number of pulse air pipes 4 and pulse valves 41 is equivalent to the number of dust filters 3; a first pressure sensor 14 for detecting the air pressure in the filter area is installed on the outer wall of the middle filter area 12 of the dust removal tank body 1, which is located below the partition 2; a second pressure sensor 15 for detecting the air pressure in the clean area is installed on the outer wall of the upper clean area 13, which is located above the partition 2; the operation of the air inlet valve 102, the air outlet valve 104 and the pulse valve 41 on the dust removal tank body 1 is triggered by the pressure difference between the first pressure sensor 14 and the second pressure sensor 15. A connecting pipe 18 is also provided between the upper clean areas 13 of the two dust removal tank bodies 1, and a connecting valve 181 is provided in the connecting pipe 18; the connecting valve 181 and the connecting pipe 18 are used to balance the pressure between the two dust removal tank bodies when switching working conditions. The connecting valve is in a closed state during normal operation and is opened when needed to balance the pressure in the two tank bodies. When one of the dust removal tank bodies 1 is in pulse backblowing, the other dust removal tank body 1 keeps filtering the dust, so the dust removal work can be uninterrupted.

[0022] The two dust removal tanks 1 of the dust removal system are installed together on the same frame 5, and an integrated touch controller 51 is also installed on the frame 5. The integrated touch controller 51 is electrically connected to the air inlet valve 102, the air outlet valve 104, the pulse valve 41, the first pressure sensor 14, and the second pressure sensor 15, and is connected to control other sensors and valves.

[0023] The back-blowing air inlet pipe 42 is provided with a third pressure sensor 421 and a temperature sensor 422 connected to the integrated touch controller 51 so as to monitor the pressure and temperature of the back-blowing air flow in real time to avoid the back-blowing dust removal effect being affected by too low or too high pressure.

[0024] When the pressure difference between the first pressure sensor 14 and the second pressure sensor 15 on one of the dust removal tank bodies 1 reaches a set value, the integrated touch controller 51 issues a command to close the air inlet valve 102 and the air outlet valve 104 on the dust removal tank body 1, and the pulse valve 41 works, and a back-blowing airflow is introduced into the pulse air pipe 4 through the back-blowing airflow inlet pipe 42. As the pulse valve 41 works, the back-blowing airflow is blown toward each dust filter 3 in a pulsed manner, so that the dust attached to the dust filter 3 falls into the dust collecting hopper; when the pressure difference does not reach the set value, the pulse valve 41 is closed, and the air inlet valve 102 and the air outlet valve 104 are reopened to perform dust filtering operations.

[0025] A dust discharge port is provided at the bottom of each dust removal tank body 1 in the frame 5 and is connected to a dust discharge valve 107 and a dust discharge tank 6. A movable caster is provided at the bottom of the dust discharge tank 6 to facilitate timely removal and replacement of the dust discharge tank. A vibrator 7 is installed on the outer wall of the dust collecting hopper 11 of the dust removal tank body 1, so that vibration is emitted during dust discharge to facilitate dust falling.

[0026] In this embodiment, the air inlet valve 102, the air outlet valve 104 and the dust exhaust valve 107 are all pneumatic butterfly valves. A manual turbine butterfly valve 108 is also connected to the air inlet pipe 101 and the air outlet pipe 103 connected to each dust removal tank 1, which can be manually adjusted when necessary.

[0027] The dust removal tank body 1 is also provided with an inspection port 16 to facilitate regular inspection and maintenance of the interior of the dust removal tank body to ensure safe and stable operation of the equipment. The inspection port 16 is also provided with a sensor switch 161, which is connected to the integrated touch controller 51. Its function is that when the inspection door of the inspection port 16 is opened, the integrated touch controller 51 controls all valves to be in a closed state, thereby ensuring that the entire system stops running and ensuring the safety of the maintenance personnel and the entire equipment.

[0028] The outer wall of the air outlet pipe 103 of each dust removal tank body 1 is also respectively connected to a vent valve 17 and a one-way check valve 19, and the connection position of the vent valve 17 and the one-way check valve 19 is closer to the dust removal tank body 1 than the air outlet valve 104. The vent valve 17 is used to empty and release pressure when necessary, and the one-way check valve 19 is used to release pressure through the one-way check valve 19 when the vent valve 17 fails, so as to prevent the tank body from becoming a pressure vessel due to the inability to release pressure, thereby avoiding safety hazards.

[0029] The inlet valve 102, the outlet valve 104, the vent valve 17, the connecting valve 181 on the connecting pipe 18 between the upper cleaning areas of the two dust removal tanks, and the bottom dust exhaust valve 107 are all provided with a valve action feedback device 9, and the valve action feedback device 9 is connected to the integrated touch controller 51. The valve action feedback device 9 can timely feedback to the PLC in the integrated touch controller 51 whether the valve switch action is in place, and if not, the fault is reported in time and the fault point is convenient to be checked.

[0030] The flange top cover 8 and the edge of the dust removal tank body 1 are respectively provided with a protruding pivoting portion 81 and connected with a pivoting rod 82, through which the flange top cover 8 can be rotated and opened relative to the dust removal tank body 1. That is, when the filter element needs to be replaced, the locking bolts of the flange top cover 8 and the dust removal tank body 1 can be unscrewed first, and then lifted up about 3-4 cm, so that the flange top cover 8 can be rotated around the pivoting rod 82 to open the top cover, so that the filter element can be easily replaced from the top, thereby improving maintenance efficiency and safety.

[0031] The working process of the utility model is as follows: the air with dust enters the dust removal tank body 1 from the air inlet duct 101, the dust with heavier specific gravity will directly settle into the dust collecting hopper 11 at the bottom, and the dust with lighter specific gravity flows with the air flow, and after being filtered by the dust filter 3 in the middle, it will gradually adhere to the dust filter 3, and the clean air enters the upper cleaning area 13 and is discharged from the top air outlet duct 103; as the amount of dust accumulated on the dust filter 3 increases, the air pressure in the upper cleaning area 13 and the air pressure in the filtering area 12 increase. The pressure difference will become larger and larger. When the pressure difference reaches the set value, the valves of the air inlet pipe 101 and the air outlet pipe 103 are first triggered to close, and then the pulse valve 41 is triggered to open. Pulse air is blown toward the dust filter 3 through the pulse air pipe 4, so that the dust attached to the dust filter 3 is blown out in the reverse direction and falls into the dust collecting hopper at the bottom, so that the dust filter 3 can restore its filtering capacity. After completion, the pulse valve 41 is closed again, and the valves on the air inlet pipe 101 and the air outlet pipe 103 are reopened to resume dust removal. When the dust accumulation in the lower dust collecting hopper reaches a certain amount, the dust exhaust valve 105 at the bottom dust exhaust port is opened, and the dust can be loaded and transported away.

[0032] Under normal circumstances, according to the settings, each dust removal tank automatically switches to alternate dust removal operation after working for half an hour. When encountering an airflow with a large amount of dust, the pulse dust removal action is switched through the pressure difference between the first pressure sensor 14 and the second pressure sensor 15, and then switches back to the filtering operation state after a certain delay.

[0033] The dust removal system of the utility model is triggered by a pressure difference between two groups of dust removal tanks, and intelligently and automatically performs pulsed back-blowing airflow to eliminate the dust adsorbed and accumulated on the dust filter and automatically drop it into the dust collecting hopper, thereby restoring the filtering capacity of the dust filter. Therefore, it can reduce manpower operation and reduce enterprise costs, and can switch without interrupting the dust removal operation, so as to ensure that the filtering capacity of the dust filter is restored to the best before being put into use, thereby extending the service life of the filter and the entire dust removal system; it also solves the problem of inconvenient dust removal, and the like. The top of the tank body is connected with a flange top cover, which makes internal assembly and maintenance more convenient, and the air outlet duct is located on the side, which can reduce the overall height, and the structural layout is more reasonable, which is convenient for assembly, maintenance and transportation.

[0034] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
