[0026] This utility model provides a dust removal device and a ton bag unloading station using it, such as Figure 1-5 As shown, the ton bag unloading station includes a receiving hopper 1 and a dust collection hopper 2. The receiving hopper 1 has a feed inlet 4 at the upper end and a discharge outlet 5 at the lower end. The dust collection hopper 2 is located slightly above and inside the receiving hopper 1, and is vertically offset from the feed inlet 4 and the discharge outlet 5. Figure 3-5 The dust collection chamber 2 and the receiving chamber 1 are separated by a partition 9, and the dust collection chamber 2 is connected to the receiving chamber 1 through multiple dust collection ports 6 provided on the partition 9. The partition 9 at the bottom of the dust collection chamber 2 is inclined, and the bottom opening 22 of the dust collection chamber 2 is provided to connect with the receiving chamber 1. The centrifugal fan 13 is connected to the dust collection chamber 2 for ventilation through the dust collection pipe 14.

[0027] refer to Figure 3-5A filter bag mounting plate 3 is fixed in the dust collection chamber 2, dividing the dust collection chamber 2 into upper and lower compartments. The filter bag mounting plate 3 has filter bag mounting openings connecting the upper and lower compartments of the dust collection chamber 2. Five filter bags 7 are inserted into the filter bag mounting openings from above and fixedly mounted on the filter bag mounting plate 3, with the filter bags 7 positioned in the lower compartment of the dust collection chamber 2. A horizontal reinforcing plate 21 is fixedly installed in the lower compartment of the dust collection chamber 2.

[0028] refer to Figure 1-3 5. A ring-shaped backflush pipe 10 is installed in the dust collection chamber 2. The backflush pipe 10 has five backflush ports 8 facing downwards. The backflush ports 8 are located above the filter bag 7 and correspond one to one. The backflush pipe 10 is connected to the air tank 12 through the air blowing pipe 11. The air tank 12 is filled with high-pressure gas. The connection between the air blowing pipe 11 and the backflush pipe 10 is T-shaped. The backflush gas in the air blowing pipe 11 is split into two paths from the T-shaped connector. The two paths supply air to the backflush ports 8 on the backflush pipe 10. The airflow blown out of the backflush ports 8 will be more stable and uniform.

[0029] A ton-bag unloading station employs the aforementioned dust removal device. One side of its receiving hopper 1 is inclined upwards and open. A receiving hopper door 15, which is sealed to the opening of the receiving hopper 1, is provided. The receiving hopper door 15 can be rotated upwards to open and downwards to close. When the receiving hopper door 15 is closed, it is sealed to the dust collection hopper 2. A gas spring 16 and a downward-pressing rotary cylinder 17 are installed on the side wall of the dust collection hopper 2. The piston rod of the gas spring 16 is hinged to the receiving hopper door 15. When the receiving hopper door 15 is opened upwards, the gas spring 16 supports the receiving hopper door 15, keeping it open. When the receiving hopper door 15 is closed, the downward-pressing rotary cylinder 17 pressurizes the receiving hopper door 15, ensuring a seal between the receiving hopper door 15 and the receiving hopper 1. An observation window 19 is provided on the receiving hopper door 15 for observation of the interior of the receiving hopper 1 when the receiving hopper door 15 is closed.

[0030] An operating platform 18 extends from the bottom of the receiving hopper 1. The operating platform 18 is located below the receiving hopper door 15. When the staff adds small packages of additives for production, the small packages of additives can be placed on the operating platform 18 for unpacking.

[0031] Combination Figure 3-5When the powdery material is unloaded, it scatters in the receiving hopper 1. Some of the powdery material falls down under gravity, while some remains suspended in the air. The suction pipe 14, suction hopper 2, and receiving hopper 1 are connected. When the centrifugal fan 13 starts working, it creates a negative pressure in the suction hopper 2, drawing in air and suspended powdery material from the receiving hopper 1 through the suction port 6. The filter bag 7 filters the powdery material, keeping it in the suction hopper 2. Some of the filtered powdery material falls down, sliding through the inclined baffle 9 to the bottom opening 22 and into the receiving hopper 1. After filtration, the centrifugal fan 13 is turned off, and the back-blowing port 8 blows air onto the filter bag 7 to clean it. The powdery material adhering to the filter bag 7 falls down through the bottom opening 22 into the receiving hopper 1.

[0032] like Figure 1 , 3 The discharge port 5 below the receiving hopper 1 is connected to the mixing mechanism of the subsequent production steps. An isolation net 20 is installed at the discharge port 5 of the receiving hopper 1 to filter out large lumps of material.

[0033] In summary, the dust removal device of this utility model and the ton bag unloading station using it, during the unloading process, create negative pressure in the dust collection chamber, forming an airflow from the external environment to the receiving chamber and the dust collection chamber. The airflow carries air and powdery materials in the air to the receiving chamber and the dust collection chamber, where the powdery materials are filtered out. The dust collection chamber also removes the scattered powdery materials in the receiving chamber, preventing them from scattering into the air. The internal back-blowing port cleans the filter bags by back-blowing, enabling the filter bags to maintain a high level of cleaning efficiency over a long period of time.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
