Description
Technical Field
[0001] This utility model relates to the field of packaging equipment technology, specifically a dust collection device for a ton packaging system for powder materials. Background Technology
[0002] Kaolin, as an important non-metallic mineral resource, is widely used in papermaking, coatings, ceramics, rubber, and cosmetics. In the papermaking industry, it is mainly used as a filler and pigment for surface coating, giving paper excellent whiteness, gloss, oil absorption, and smoothness. Particle size is one of the important indicators for evaluating the quality of kaolin products. Paper coatings often use a 2μm percentage to evaluate the particle size of pigments. The particle size range of ultrafine kaolin for coating is usually ≥80% (<2μm), with the better if the particle size is between 1μm and 1.5μm. Therefore, kaolin for papermaking is a fine powder. Fine powder is extremely prone to generating dust during packaging. However, dust collection devices in the packaging process have always been a technical challenge in the field of powder material packaging.
[0003] Powder material packaging technology is divided into small bag packaging and ton bag packaging. Currently, small bag packaging technology is relatively mature, widely used, highly automated, and its dust collection devices are also relatively mature. However, ton bag packaging technology, due to its large equipment size and complex packaging process, often requires manual operation and intervention. A satisfactory solution for its dust collection device has yet to be found, thus exposing operators to a dusty environment. The dust generated during the packaging process poses a health hazard. Therefore, it is necessary to develop a dust collection device suitable for ton bag packaging machines. Utility Model Content

Detailed Implementation
[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0025] Please refer to Figures 1 to 5 The present invention relates to a dust collection device for a ton packaging system for powder materials, comprising a dust collector, a manifold pipe 5, and multiple ton packaging machines.
[0026] The dust collector includes a dust collection housing 13 and an air exhaust pipe 15. An exhaust fan is provided on the air exhaust pipe 15. A dust collection filter cartridge and a pulse filter cartridge dust collector are provided inside the dust collection housing 13. A dust collection outlet is provided at the bottom of the dust collection housing 13.
[0027] Each of the aforementioned ton packaging machines includes an outer shell 1 and a feeding mechanism. The feeding mechanism is provided with a feeding port 17 below it, and a ton bag 9 is connected below the feeding port 17. The ton bag 9 is hung on the feeding mechanism. A roller conveyor belt 11 is also provided below the feeding port 17. The feeding mechanism is used to quantitatively input kaolin powder into the ton bag 9. The outer casing 1 is provided with a roller shutter door 4 on its side. Specifically, each outer casing 1 has front and rear side openings. The front and rear side openings of the outer casing 1 facilitate the installation of the roller conveyor belt 11. The outer casing 1 is provided with two roller shutter doors 4, both of which are electric roller shutter doors 4. The two roller shutter doors 4 are respectively set in the front and rear side openings of the outer casing 1. After the feeding mechanism fills the ton bag 9, it forms a ton bag finished product. The ton bag finished product falls onto the roller conveyor belt 11 under the operation of the operator. The roller conveyor belt 11 can transport the ton bag finished product out of the outer casing 1. The roller shutter door 4 is used to close the front and rear side openings of the outer casing 1 during the feeding process of the feeding mechanism. This prevents kaolin dust from overflowing from the outer casing, ensures a clean working environment during the packaging process, and reduces the harm of dust generated during the packaging process to the human body.
[0028] All outer casings 1 of the ton packaging machines are equipped with dust collection pipes 2 at their tops. All dust collection pipes 2 are connected to the manifold 5, which is connected to the air inlet of the dust collection housing 13. An exhaust fan maintains a negative pressure inside the outer casing 1, thereby drawing a large amount of dust generated during material feeding into the dust collection housing 13. The dust is then collected by dust collection filter cartridges and a pulse jet dust collector, achieving the recycling of the kaolin. The dust collection filter cartridges adsorb and filter the kaolin dust passing through them, ensuring that the gas discharged from the air exhaust pipe 15 meets emission requirements. The pulse jet dust collector periodically pulse-jet-cleans the dust collection filter cartridges, causing the adsorbed dust to fall off and ensuring continuous use of the dust collection filter cartridges.
[0029] In a preferred embodiment, each of the dust collection ducts 2 is equipped with an airflow regulating valve 14. The airflow regulating valve 14 is a manually adjustable butterfly valve, used to regulate the ventilation volume of the dust collection duct 2. Because the distance between each packaging machine and the exhaust fan of the dust collector varies, the air pressure distribution is uneven, easily leading to significant differences in airflow. This causes the dust collection duct to lose balance, reducing the efficiency of the pulse-jet filter dust collector's fan and affecting the dust collection effect. Adjusting the opening of the manually adjustable butterfly valve according to the distance ensures uniform air pressure in the dust collection duct 2, preventing uneven air pressure from affecting the dust collection effect.
[0030] In a preferred embodiment, a bellows cover 6 is provided on the outside of the discharge port, surrounding the discharge port, and the end of the dust collection pipe is connected to the top of the bellows cover 6. A permanent magnet metal hook 8 is provided at the bottom of the bellows cover 6, and an electromagnet 7 is provided at the top of the bellows cover 6. The electromagnet 7 is used to attract the permanent magnet metal hook 8 when energized, causing the bellows cover 6 to contract. When the discharge port discharges material, the electromagnet 7 is de-energized, and the bellows cover 6 descends, thereby covering the connection between the ton bag 9 and the discharge port. This ensures the effective suction of kaolin dust by the dust collection pipe.
[0031] In a preferred embodiment, transparent fixed baffles are provided on both sides of the roller shutter door 4. The fixed baffles 10 are fixed on the outer shell, and the edge of the roller shutter door 4 is slidably connected to the fixed baffles. The fixed baffles 10 are made of transparent and visible PVC material, which makes it convenient for operators to observe the packaging situation.
[0032] The roller shutter door 4 is also equipped with a roller shutter door controller 3 to control the raising and lowering of the roller shutter door 4. The roller shutter door controller 3 allows workers to manually operate the raising and lowering of the roller shutter door 4. The roller conveyor belt 11 is also equipped with a photoelectric sensor 12. The photoelectric sensor 12 is used to sense the raising and lowering status of the roller shutter door. After the roller shutter door 4 is opened, the photoelectric sensor 12 controls the roller conveyor belt 11 to start, so as to transport the finished ton-bag products after they have been packaged.
[0033] In a preferred embodiment, the diameter of the manifold 5 is 2-5 times that of the dust collection duct. The manifold 5 is made of UPVC material.
[0034] In a preferred embodiment, the lower part of the dust collection housing 13 is funnel-shaped, the dust collection outlet is located at the bottom of the funnel-shaped dust collection housing 13, and a dust collection bucket 16 is connected below the dust collection outlet. The pulse filter cartridge dust collector periodically pulse-jet blows the dust collection filter cartridge, which can blow off the kaolin dust adsorbed on the dust collection filter cartridge. The dust collection bucket 16 is used to collect the kaolin dust and reuse it.
