Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly relates to a structure for preventing secondary pollution during powder bagging. Background Art

[0002] When the current discharging machine is loading materials, generally, the receiving bag is sleeved at the lower material outlet without being sealed. During the discharging process, the gas discharged from the bag will carry dust and overflow from the bag mouth, which will not only cause environmental pollution and damage the health of workers, but also lead to the waste of valuable dust. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and provide a structure for preventing secondary pollution during powder bagging, which can effectively prevent dust from overflowing and thus avoid environmental pollution.

[0004] In order to achieve the above-mentioned invention purpose, the present invention provides the following technical solutions:

[0005] A structure for preventing blockage and secondary pollution during powder bagging, including a feeding transfer bin and a conical bin; the conical bin is fixed at the lower end of the feeding transfer bin, and a discharging pipe is arranged at the output end of the conical bin;

[0006] A dust recovery assembly, the dust recovery assembly includes a housing, an exhaust pipeline and a dust collector. The housing is fixed on the outer walls of the conical bin and the discharging pipe. The housing and the outer walls of the conical bin and the discharging pipe form an air extraction chamber. The exhaust pipeline is communicated with the air extraction chamber, and the dust collector is connected to the end of the exhaust pipeline far from the housing;

[0007] An airbag pressing assembly, the airbag pressing assembly includes a fixing plate and an airbag. The fixing plate is arranged on the outer wall of the conical bin, and the airbag is fixedly arranged on one edge of the fixing plate or the outer wall of the discharging pipe.

[0008] Further, a gravity baffle is arranged in the discharging pipe.

[0009] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0010] During actual use, the bagging material opening is sleeved on the discharging pipe, and the airbag is inflated. The airbag and the edge of the fixing plate tightly clamp the bagging material opening, so as to ensure that the bagging material opening and the discharging pipe are in a sealed state, thereby avoiding the leakage of powder and polluting the environment. At the same time, under the action of the dust collector, the dust will enter the dust recovery system through the air extraction cavity and the exhaust pipeline for recovery.

[0015] The present invention will be further described in detail below in conjunction with test examples and specific implementation manners. However, it should not be understood that the scope of the above-mentioned subject matter of the present invention is limited to the following embodiments. All technologies implemented based on the content of the present invention belong to the scope of the present invention.

[0016] In this embodiment, a powder bagging anti-secondary pollution structure is provided, as Figure 1 - Figure 2 shown, which includes a blanking transfer bin 1 and a conical bin 2; the conical bin 2 is fixed to the lower end of the blanking transfer bin 1, and a discharge pipe 3 is provided at the output end of the conical bin 2;

[0017] A dust recovery assembly, the dust recovery assembly includes a housing 4, an exhaust duct 5 and a dust collector 6, the housing 4 is fixed on the outer walls of the conical bin 2 and the discharge pipe 3, the housing 4 and the outer walls of the conical bin 2 and the discharge pipe 3 form an air extraction chamber 10, the exhaust duct 5 is connected to the air extraction chamber 10, and the dust collector 6 is connected to one end of the exhaust duct 5 away from the housing 4;

[0018] An airbag pressing assembly, the airbag pressing assembly includes a fixing plate 7 and an airbag 8, the fixing plate 7 is arranged on the outer wall of the conical bin 2, and the airbag 8 is fixedly arranged on one edge of the fixing plate 7 or the outer wall of the discharge pipe 3.

[0019] As Figure 1 shown, during actual use, place the bagging opening between the airbag 8 and the edge of the fixing plate 7, and then inflate the airbag 8, so as to ensure that the bagging opening is in a sealed state with the discharge pipe 3, thereby avoiding powder leakage and polluting the environment. At the same time, under the action of the dust collector, dust will enter the dust recovery system through the air extraction cavity 10 and the exhaust duct 5 for recovery

[0020] As Figure 2 shown, during actual use, place the bag opening of the bagging between the discharge pipe 3 and the airbag 8, and then inflate the airbag 8. The airbag 8 squeezes the bag opening of the bagging against the outer wall of the discharge pipe 3, so that the inner wall of the bag opening of the bagging is in close contact with the outer wall of the discharge pipe 3, thereby avoiding powder leakage and polluting the environment. At the same time, under the action of the dust collector, dust will enter the dust recovery system through the air extraction cavity 10 and the exhaust duct 5 for recovery

[0021] Further optimize the above embodiments. A gravity baffle 9 is provided in the discharge pipe 3. Under the action of the gravity of the powder material, the gravity baffle 9 opens and then falls into the bag. Such a setting can prevent the small amount of residual powder material in the discharge pipe 3 from continuing to fall at the end of bagging.

[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
