[0037] Reference Figure 1-Figure 6 , the embodiment of the present application provides a dust removal device, comprising:

[0038] The housing 1 has a receiving space formed therein, and a dust suction port 101 is provided on the housing 1;

[0039] The partition plate 2 is arranged in the accommodating space and divides the accommodating space into a first space 102 and a second space 103 , and the dust suction port 101 is connected to the second space 103 ;

[0040] The filter cartridge 3 is disposed on the partition plate 2, and a filter port 31 is formed on the filter cartridge 3. A plurality of air inlets connected to the filter port 31 are formed on the peripheral side of the filter cartridge 3. The filter port 31 is connected to the first space 102, and the air inlet is connected to the second space 103;

[0041] a negative pressure member 4, disposed on the housing 1 and communicating with the first space 102; and

[0042] The purge mechanism comprises an air source, and the air source is connected to the filter port 31 through a first air pipe.

[0043] Dust will be generated during the unpacking of ton bags. The negative pressure member 4 can be a centrifugal blower or a fan, etc., so as to perform negative pressure work. The air is blown to the first space 102 through the dust suction port 101, the air inlet, and the filter port 31 in sequence, so that the dust can be concentrated and attached to the surrounding side of the filter cartridge 3 located in the second space 103 under the action of negative pressure. After a certain amount of dust is attached to the filter cartridge 3 or after the unpacking of the ton bag is completed, the air source is ventilated toward the filter port 31 through the first air pipe, and the gas provided by the air source passes into the inside of the filter cartridge 3 through the filter port 31, and blows toward the air inlet of the filter cartridge 3 from the inside of the filter cartridge 3, thereby blowing off the dust attached to the filter cartridge 3 and collecting it, so as to prevent the waste materials such as material debris, dust, and flying debris from escaping during the unpacking process, and solve the problem of dust polluting the on-site environment during the unpacking of ton bags and causing adverse effects on human health and equipment.

[0044] In some embodiments, the gas source can be an on-site gas source, or a gas tank 5; the gas tank 5 is composed of an electromagnetic pulse valve 51, a pressure regulating filter valve 52, a single-port gas tank 53, a mini ball valve 54, a pipe cap 55 and a mounting plate 56.

[0045] The housing 1 is provided with a detection member 6 electrically connected to the gas source, wherein the first detection position of the detection member 6 is used to detect the air pressure in the first space 102, and the second detection position of the detection member 6 is used to detect the air pressure in the second space 103. The detection member 6 can be fixed to the housing 1 by welding or bolts, and connected to the first detection position and the second detection position by a detection tube. During the operation of the negative pressure member 4, as the dust gradually adheres to the filter cartridge 3, a certain pressure difference will be formed on both sides of the partition 2, i.e., the first space 102 and the second space 103. After breaking through the detection threshold of the detection member 6, the signal is transmitted to the gas source, and the gas source provides gas to the filter port 31 to blow off the dust attached to the filter cartridge 3, thereby realizing automatic control, enabling the reuse of the scattered materials, reducing the material loss in the automatic unpacking process of the ton bag, eliminating the sanitary dead corner, and eliminating the need for manual secondary cleaning, thereby improving production efficiency. The detection member 6 can be a pressure sensor or other components that can also realize air pressure detection.

[0046] In some embodiments, the dust suction port 101 can be opened on any wall surface of the shell 1. Usually, the dust suction port 101 is opened on the bottom wall surface of the shell 1 or on the side wall surface of the shell 1. This embodiment is described by taking the dust suction port 101 opened on the side wall surface of the shell 1 as an example.

[0047] The dust suction port 101 is formed on the first side wall of the shell 1, and the second side wall of the shell 1 is arranged opposite to the first side wall. The second side wall includes an upper part and a lower part connected to the upper part and located below the upper part, and the lower part is inclined in the direction away from the upper part toward the dust suction port 101; the dust located on the upper surface moves to the surface of the lower part under the action of its own gravity, and the inclined setting of the lower part allows the dust located on the lower surface to move toward the direction of the dust suction port 101 under the action of gravity, thereby being collected through the dust suction port 101.

[0048] A purge pipe 7 connected to the gas source is provided in the second space 103, and a plurality of purge holes 8 are provided on the purge pipe 7; the inside of the housing 1 is purged through the purge holes 8 to reduce dust attached to the inside of the housing 1 and ensure the dust collection effect.

[0049] Of course, part of the dust attached to the lower surface will move toward the dust suction port 101 due to its own gravity or other reasons, and thus be collected; part of the dust will also remain on the lower surface. Therefore, the purge hole 8 is arranged toward the lower part, so that the dust attached to the lower part is blown away and collected through the dust suction port 101.

[0050] A plurality of filter cartridges 3 are arranged at intervals in the housing 1, and the use effect of the dust removal device is ensured by the arrangement of the plurality of filter cartridges 3. Among them, the plurality of filter cartridges 3 include filter cartridges 3 provided with two, three or more. The technician can make adaptive adjustments according to different use requirements in different application scenarios. Of course, in order to facilitate the adjustment of the number of filter cartridges 3 in the housing 1, the filter cartridge 3 is detachably arranged on the partition 2. Among them, the filter cartridge 3 includes a fixed cover plate 32, a filter element 33 and a lower cover plate 34 connected from top to bottom, the air inlet is formed on the peripheral side of the filter element 33, the filter element 33 is a hollow structure inside, and its upper and lower ends are open structures, the lower cover plate 34 closes the bottom opening of the filter element 33, and the upper opening of the filter element 33 is the filter port 31, the fixed cover plate 32 is connected to the top of the filter element 33 but does not close the filter port 31, and the fixed cover plate 32 is used to be detachably connected to the cover plate, for example, the fixed cover plate 32 is bonded to the partition 2, or is screwed to the partition 2 by bolts or screws. Exemplarily, the present application describes an example in which four filter cartridges 3 are provided and distributed in a rectangular shape.

[0051] Optionally, the filter cartridge 3 includes a flat-frame filter cartridge, and the cross-sectional shape of the filter cartridge 3 is rectangular. By adopting a rectangular flat-frame filter cartridge, the space occupied by the filter cartridge 3 is reduced, and the overall volume of the device is reduced while ensuring the dust removal effect of the dust removal device.

[0052] In summary, the negative pressure part 4 on the dust removal device provides negative pressure, and some of the escaped material particles may be in the lower part of the shell 1 during the bag breaking process, and some of the scattered dust particles are attracted and attached to the filter cartridge 3. When the attached dust particles accumulate to a certain number, a certain pressure difference will be formed in the area on both sides of the partition 2. After breaking through the detection threshold of the pressure sensor, a signal will be transmitted to the gas storage tank 5, and the electromagnetic pulse valve 51 will be opened. The compressed gas in the single-port gas storage tank 53 is blown into the inside of the filter element 33 to blow off the dust particles attached to the filter element 33; at the same time, the compressed gas is blown out through the purge hole 8 of the purge pipe 7 to purge the dust particles accumulated in the lower part of the dust removal device, so that the material dust particles are collected. The dust removal device provided by the present application has a simple and beautiful structure, a simple and reliable fixing method, and is easy to disassemble and maintain, which reduces the maintenance difficulty of equipment maintenance personnel.

[0053] Reference Figure 1-Figure 7The embodiment of the present application further provides an unpacking device, comprising a frame 9, an unpacking bin 10 disposed on the frame 9, and a dust removal device as described in the above embodiment, wherein a feed port is provided on the unpacking bin 10, and a dust suction port 101 of the dust removal device is connected to the feed port, and a protective cover 11 is further provided on the frame 9, and the feed port is sealed by the outer shell 1 of the dust removal device, the protective cover 11, and the frame 9. The outer shell 1 of the dust removal device can be welded and fixed to the frame 9, or the dust removal device can be detachably disposed on the frame 9 through a connecting assembly, and the connecting assembly can be in the form of a snap fit or a bolt fit.

[0054] The ton bag is set in the unpacking bin 10 through the feed port of the unpacking bin 10, and the unpacking operation is carried out in the unpacking bin 10. The dust generated by the ton bag during the unpacking process will be scattered through the feed port. The feed port of the unpacking bin 10 is sealed by the outer shell 1, protective cover 11 and frame 9 of the dust removal device, and the dust suction port 101 is connected with the feed port to ensure that the dust flying from the feed port will enter the outer shell 1 of the dust removal device through the dust removal port under the negative pressure of the negative pressure member 4, and adhere to the surface of the filter cartridge 3 of the dust removal device, thereby realizing the centralized collection of dust. When a certain amount of dust is attached to the filter cartridge 3, air is ventilated into the inside of the filter cartridge 3 through the filter port 31, so that the dust particles on the surface of the filter cartridge 3 are blown off. At the same time, the air source is purged toward the inner wall of the outer shell 1 through the purge hole 8, so that the dust particles accumulated on the inner wall can also fall back into the unpacking bin 10.

[0055] The dust removal device is provided with two groups, and the two groups of dust removal devices are arranged on opposite sides of the unpacking bin 10; the side suction and symmetrical distribution are adopted, so that the dust removal device has a large dust removal area and high efficiency, and can effectively control the material dust particles scattered in the unpacking bin 10, and prevent the dust particles from escaping to the outside of the equipment to endanger the health of personnel and the safety of the equipment.
