Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0031] like Figure 1-Figure 6 As shown:

[0032] A bag dust collecting device provided in one embodiment of the present application comprises a box body 1, and a detachable box cover 2 is fixed to the upper end of the box body 1. A plurality of filter bags 4 distributed in an array are installed inside the box body 1 through a partition 3. Specifically, the edge of the partition 3 is sealed and welded to the inside of the box body 1, and the partition 3 is provided with a plurality of through holes distributed in an array, and each through hole is connected to the upper end of the filter bag 4.

[0033] A rotatable and lockable blowing structure 10 is provided on the upper side of each column of filter bags 4 , and the jet end of the blowing structure 10 can be rotated to the top of each column of filter bags 4 and blow gas to each column of filter bags 4 .

[0034] The blowing structure 10 is rotatably and sealingly connected to an air inlet pipe 5 fixedly connected to the box body 1. Specifically, the air inlet pipe 5 passes through the box body 1 and is sealed and welded to the box body 1. The air inlet pipe 5 is connected to an air supply device 11 that can provide pulsed compressed air thereto, and the air supply device 11 is installed on the outer wall of the box body 1.

[0035] When in use, the jet end of the spray structure 10 is located directly above the filter bag 4, and the air supply device 11 provides pulse compressed air to the spray structure 10 through the air inlet pipe 5. The spray structure 10 sprays pulse compressed air to the filter bag 4 to clean the filter bag 4. When the filter bag 4 needs to be replaced, after opening the box cover 2, first release the lock of the spray structure 10 above the filter bag 4 to be replaced, then rotate the spray structure 10 to the side of the filter bag 4 and lock the spray structure 10 again, and then replace the filter bag 4. The spray structure 10 is locked. During the process of replacing the filter bag 4, even if the spray structure 10 is accidentally touched, the spray structure 10 will not affect the replacement of the filter bag 4. After the replacement of the filter bag 4 is completed, the jet end of the spray structure 10 is rotated to the top of the filter bag 4 and the spray structure 10 is locked, and then the box cover 2 can be closed to complete the replacement of the filter bag 4.

[0036] The bag dust collecting device provided in the present embodiment is provided with a plurality of filter bags 4 distributed in an array through the inside of the box body 1, and a rotatable and lockable blowing structure 10 is provided on the upper side of each column of filter bags 4, and the jet end of the blowing structure 10 can move to the top of each column of filter bags 4 and blow gas to each column of filter bags 4, and the blowing structure 10 is rotatably and sealingly connected to an air inlet pipe 5 fixedly connected to the box body 1, and the air inlet pipe 5 is connected to an air supply device 11 that can provide pulsed compressed air therefor. When in use, the jet end of the blowing structure 10 is located just above the filter bag 4, and the blowing The structure 10 sprays pulse compressed air on the filter bag 4 to clean the dust. When the filter bag 4 needs to be replaced, it is only necessary to release the lock of the spray structure 10 above the filter bag 4 to be replaced, and rotate the spray structure 10 to the side of the filter bag 4. After locking the spray structure 10 again, the filter bag 4 can be replaced. After the filter bag 4 is replaced, the spray structure 10 can be rotated and reset. Compared with the existing method of replacing the filter bag 4, there is no need to use a wrench to disassemble and assemble multiple bolts. Not only is the operation simple, but it can also shorten the replacement time of the filter bag 4 and improve the replacement efficiency of the filter bag 4.

[0037] In some embodiments of the present application, the blowing structure 10 includes an air duct 101 located on the side of the filter bag 4, and the air duct 101 is a hollow structure with one end open. The open end of the air duct 101 is rotatably and sealedly connected to the air inlet pipe 5, and the closed end of the air duct 101 is rotatably connected to a mounting base 9 fixed on the partition 3, and the air duct 101 can be locked after rotation.

[0038] The air guide pipe 101 is fixedly connected with L-shaped blowing pipes 102 which are equal in number and correspond to each row of filter bags 4 , and the jet end of each L-shaped blowing pipe 102 can rotate to the top of the corresponding filter bag 4 and spray gas to the filter bag 4 .

[0039] In this embodiment, the L-shaped blowing pipe 102 is composed of a first pipe 103 and a second pipe 104 that are perpendicular to each other, one end of the first pipe 103 is connected to the air guide pipe 101, the other end of the first pipe 103 is connected to one end of the second pipe 104, and the other end of the second pipe 104 is the jet end of the L-shaped blowing pipe 102. After the jet end of the L-shaped blowing pipe 102 rotates to just above the filter bag 4, the second pipe 104 is vertically distributed, and the first pipe 103 is horizontally distributed.

[0040] When in use, the air supply device 11 provides pulsed compressed air to the air guide pipe 101 through the air inlet pipe 5, and the pulsed compressed air in the air guide pipe 101 is sprayed into the filter bag 4 through the L-shaped blowing pipe 102 to clean the filter bag 4. When replacing the filter bag 4, the air guide pipe 101 is rotated counterclockwise, and the air guide pipe 101 drives the L-shaped blowing pipe 102 to rotate counterclockwise synchronously with it. After the L-shaped blowing pipe 102 rotates to the side of the filter bag 4, the L-shaped blowing pipe 102 is locked, and the L-shaped blowing pipe 102 is now blocked from the filter bag 4, and then the filter bag 4 is replaced. After the replacement of the filter bag 4 is completed, the air guide pipe 101 is rotated clockwise, and the air guide pipe 101 drives the L-shaped blowing pipe 102 to rotate clockwise. After the second pipe 104 of the L-shaped blowing pipe 102 is located above the filter bag 4 and is vertically distributed, the air guide pipe 101 can be locked.

[0041] In some embodiments of the present application, a driving rod 6 is fixed on the air guide tube 101 , and a sliding sleeve 7 is sleeved on the driving rod 6 and is slidably connected to the driving rod 6 .

[0043] The mounting seat 9 is provided with a first plug hole 91 and a second plug hole 92 .

[0044] Among them, after the jet end of the L-shaped blowing pipe 102 rotates to the top of the filter bag 4, the sliding sleeve 7 can be inserted into the first insertion hole 91, and after the jet end of the L-shaped blowing pipe 102 rotates to the side of the filter bag 4, the sliding sleeve 7 can be inserted into the second insertion hole 92.

[0045] When in use, the initial state is: the jet end of the L-shaped blowing pipe 102 is located directly above the filter bag 4, and the sliding sleeve 7 is inserted into the first insertion hole 91. When replacing the filter bag 4, the staff holds the sliding sleeve 7 and moves the sliding sleeve 7 out of the first insertion hole 91, then pushes the sliding sleeve 7 to rotate counterclockwise, and the sliding sleeve 7 drives the air guide pipe 101 to rotate counterclockwise through the driving rod 6, and the air guide pipe 101 drives the L-shaped blowing pipe 102 to rotate counterclockwise. When the L-shaped blowing pipe 102 rotates to the side of the filter bag 4, the sliding sleeve 7 is inserted into the second insertion hole 92, and the filter bag 4 can be replaced. After the filter bag 4 is replaced, the staff holds the sliding sleeve 7 again, moves the sliding sleeve 7 out of the second insertion hole 92, and pushes the sliding sleeve 7 to rotate clockwise. After the jet end of the L-shaped blowing pipe 102 is located directly above the filter bag 4, the sliding sleeve 7 is inserted into the first insertion hole 91. Therefore, it is only necessary to operate the sliding sleeve 7 to release the blowing structure 10 from blocking the filter bag 4 and to reset the blowing structure 10, which is convenient to operate and use.

The air bag 111 is connected to the same number of intake pipes 5 and one-to-one correspondence, and each pulse valve 112 is connected to the corresponding intake pipe 5. The air bag 111 provides pulse compressed air to the intake pipe 5 through the pulse valve 112.
