Description

Technical Field

[0001] This utility model relates to the field of powder packaging technology, specifically to a packaging device for polyferric sulfate powder. Background Technology

[0002] Polyferric sulfate, as a high-performance inorganic polymeric flocculant, is widely used in water treatment, industrial wastewater purification, and other fields. Since it is often stored and transported in powder form, it requires bagging and packaging in the later stages of production.

[0003] In common powder packaging equipment, the material falls into the packaging bag through a hopper during operation. The air inside the bag is compressed as the material enters, carrying some fine powder upwards. Although some existing equipment is equipped with simple air extraction or dust removal structures, continuous air extraction during the filling process will remove a large amount of powder, which is wasteful. Stopping the air extraction will cause the gas to carry dust and be discharged, polluting the work area. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a packaging device for polyferric sulfate powder, which solves the issues of excessive powder waste during air extraction and dust dispersion when air extraction is stopped.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: a packaging device for polyferric sulfate powder, comprising a base, a feeding hopper, a clamp, and an extraction assembly, further comprising an extraction hood, a support cylinder, a lifting mechanism, and a partition plate. The feeding hopper is fixedly installed on the top of the base, the clamp is located on the front side of the base, the extraction assembly is located on the rear side of the base, the extraction hood is fixedly installed on the extraction end of the extraction assembly, the support cylinder is fixedly installed on the front side of the base, and the bottom outlet of the feeding hopper and the extraction hood are located inside the support cylinder. The lifting mechanism is located on the surface of the support cylinder, the partition plate is slidably installed inside the support cylinder, and the partition plate is threadedly installed on the rotating end surface of the lifting mechanism. The partition plate is sleeved on the bottom surface of the feeding hopper, and the partition plate and the extraction hood are correspondingly arranged.

[0006] The air extraction hood includes an air inlet hood and a fixing block. The air inlet hood is fixedly installed at the front air intake of the air extraction assembly, and the fixing block is fixedly installed on the side of the air inlet hood near the inner wall of the support cylinder. The air inlet hood is equipped with a filter bag inside, and its bottom opening is equipped with a protective net.

[0007] The fixing block and the support cylinder are slidably inserted together, and a magnetic block is embedded in the surface of the fixing block.

[0008] The support cylinder includes a cylinder body and a fixing slot. The cylinder body is fixedly installed on the front side of the base, and the fixing slot is fixedly installed inside the cylinder body and located on one side of the exhaust hood.

[0009] The number of fixed slots is multiple sets, and the multiple sets of fixed slots are arranged at equal intervals on the inner wall of the cylinder.

[0010] The lifting mechanism includes a motor, a screw, and transmission wheels. The motor is fixedly installed on the front side of the base, the screw is rotatably installed inside the support cylinder, and there are two sets of transmission wheels. One set of transmission wheels is fixedly installed on the output end of the motor, and the other set of transmission wheels is fixedly installed on the top of the screw. The two sets of transmission wheels are meshed together.

[0011] The partition plate includes a plate body, a baffle, a sealing ring, and a pressure sensor. The plate body is slidably installed inside the support cylinder, and the plate body is threadedly connected to the rotating end of the lifting mechanism. The plate body is slidably sleeved on the bottom surface of the feeding hopper. A vent is opened on the surface of the plate body. The baffle is rotatably installed at the vent, the sealing ring is fixedly installed inside the vent, and the pressure sensor is located at the bottom of the plate body.

[0012] There are two sets of baffles and sealing rings, which are symmetrically arranged. The sealing rings are attached to the top of the baffles, and the baffles are located directly below the exhaust hood, corresponding to it.

[0013] The beneficial effects of this utility model are as follows: This invention uses a motor to drive the transmission wheel at its output end to rotate. Through the meshing transmission of two sets of transmission wheels, the screw rotates, and the screw drives the disc on its surface to move up and down inside the cylinder. When conveying polyferric sulfate powder into the packaging bag, the disc gradually moves upward. Relying on the disc, baffle, and sealing ring to block the gas, the gas cannot freely drift upward from the cylinder, preventing the powder from drifting to the outside. The gradually moving partition disc can prevent the gas pressure inside the packaging bag from being too high, causing the gas to carry the powder and break through the packaging bag. After the material is conveyed, the disc moves up until the baffle contacts the bottom of the air inlet hood, and is pushed open and flipped. The air extraction component can then draw the airflow below the air inlet hood to extract the powder that has drifted at the top of the packaging bag, making it convenient for the packaging bag to be moved to the subsequent sealing equipment to continue the next process. Through the adsorption connection between the fixed block and the fixed slot, the height position of the air inlet hood can be adjusted according to the required capacity of the packaging bag. After the filling is completed, the disc continues to move upward until the baffle is pushed open by the air inlet hood. Attached Figure Description

[0019] The air extraction hood 5 includes an air inlet hood 501 and a fixing block 502. The air inlet hood 501 is fixedly installed at the front air intake of the air extraction assembly 4. The fixing block 502 is fixedly installed on the side of the air inlet hood 501 near the inner wall of the support cylinder 6. The air inlet hood 501 is equipped with a filter bag inside, and its bottom opening is equipped with a protective net. Specifically, the air intake hood 501 is used to clean the powder floating in the air at the top of the packaging bag, and the air intake hood 501 is fixed to the corresponding height inside the support cylinder 6 by the fixing block 502.

[0020] The fixing block 502 and the fixing slot 602 are slidably inserted into each other. A magnetic block is embedded in the surface of the fixing block 502 and is correspondingly set with the fixing slot 602.

The sealing rings 803 are attached to the top of the baffles 802 to seal the edge of the vent blocked by the baffles 802.

[0026] In summary: When using this utility model, the operator places the packaging bag onto the bottom of the cylinder 601, and drives the suction assembly 4 to clamp the bag opening to the surface of the cylinder 601. At this time, the baffle 802 and the disc 801 block and seal the internal flow of the cylinder 601. The feeding hopper 2 is then driven to fill the packaging bag with polyferric sulfate powder. As the material is added, some air will be trapped inside the bag. To ensure stable air pressure inside the packaging bag, the drive motor 701 drives the transmission wheel 703 at its output end to rotate. Relying on the meshing transmission of the two sets of transmission wheels 703, the screw 702 is driven to rotate. 702 drives the disc 801 to move upward inside the cylinder 601. The air pressure sensor 804 detects the change in air pressure inside the bag. The operator operates the control panel to make the disc 801 move upward steadily. During this process, the disc 801, baffle 802 and sealing ring 803 prevent the gas from carrying powder away. After the polyferric sulfate powder filling is completed, it continues to move upward until the bottom of the air inlet hood 501 contacts the baffle 802, pushing it to overcome the torsion spring and flip downward. The air extraction component 4 draws air to make the air inlet hood 501 clean the powder floating in the air at the top of the packaging bag, which is convenient for the subsequent packaging bag sealing operation.
