Description

Technical Field

[0001] This utility model belongs to the field of powder packaging technology, specifically relating to a lightweight calcium carbonate packaging system. Background Technology

[0002] Light calcium carbonate is an important industrial raw material, widely used in rubber, plastics, papermaking, coatings, inks, metallurgy, glass and other fields.

[0003] Because light calcium carbonate has a narrow particle size distribution (typically 0.02-0.1 μm), it is an ultrafine powder with irregular particle shapes such as spindles and lumps. Its large specific surface area makes it prone to forming barriers and entanglements between particles, increasing adsorption and friction, and severely affecting its flowability. Furthermore, the relatively high content of fine particles in light calcium carbonate makes it easy to absorb moisture from the air, leading to agglomeration. This agglomeration reduces the lubrication between the particles and container walls or other contact surfaces, further affecting the material's flowability.

[0004] Traditional light calcium carbonate storage and packaging silos are relatively small, typically employing a simultaneous feeding and packaging method, resulting in low production and packaging efficiency. Conversely, when using large silos for storing and packaging light calcium carbonate, the irregularity of its particles and the formation of agglomerates cause the material to easily clump together, leading to uneven material distribution within the silo and obstructed discharge, thus complicating packaging operations. Furthermore, the clumps are difficult to accurately measure during packaging, severely impacting the accuracy of the packaged weight.

[0005] In addition, light calcium carbonate has a strong hygroscopic property. During the storage and packaging process in a large warehouse, if the humidity inside the warehouse is not properly controlled, the material is prone to absorbing moisture from the air and becoming damp, which then adheres to the warehouse walls and remains on the equipment. This not only increases the difficulty of cleaning but also affects the effective use of the packaging warehouse space and the normal operation of the equipment.

[0006] In view of this, it is indeed necessary to provide a lightweight calcium carbonate packaging system that can solve the above problems in order to improve production and packaging efficiency. Summary of the Invention

[0007] Based on the shortcomings of the prior art mentioned in the background section, the purpose of this utility model is to provide a lightweight calcium carbonate packaging system to solve problems such as poor material discharge, inaccurate packaging weight, and material adhesion to equipment, thereby improving production and packaging efficiency.

[0008] To achieve the above objectives, this utility model provides a lightweight calcium carbonate packaging system, comprising: a packaging chamber, a packaging machine, and an air pipeline, wherein the top of the packaging chamber is equipped with a dust collector and a feeding port, the bottom of the packaging chamber is equipped with a vibration motor, the bottom of the packaging chamber has a conical structure, and the end of the conical structure of the packaging chamber is equipped with a discharge port;

[0009] The packaging machine is connected to the discharge port at the bottom of the packaging chamber via a short connecting pipe. A star-shaped feeder is provided on the short connecting pipe, and a compressed air purging pipeline is connected to the short connecting pipe between the discharge port and the star-shaped feeder.

[0010] The air pipeline is connected to an air filter, a Roots blower, and a gas distribution platform. The gas distribution platform has multiple flow-aiding pipelines, which surround the outer periphery of the conical structure at the bottom of the packaging chamber from top to bottom. The flow-aiding pipelines are placed parallel and coaxially, and their central axes coincide with the central axis of the packaging chamber. Each flow-aiding pipeline has multiple branch pipes, which are evenly distributed along the outer periphery of the packaging chamber and inserted into the conical structure of the packaging chamber. The branch pipes are welded to the packaging chamber, and each branch pipe is connected to a fluidizer at its end.

[0011] Furthermore, the height of the vibration motor installation position from the end of the packaging bin conical structure is 1 / 4 to 1 / 2 of the total height of the packaging bin conical structure.

[0012] Furthermore, the operation of the vibration motor is controlled by a time relay.

[0013] Furthermore, the air pipeline is equipped with a safety valve and a check valve.

[0014] Furthermore, a pressure gauge is provided on the gas distribution platform.

[0015] Furthermore, the flow-aiding pipeline is equipped with valves and flow meters.

[0016] Furthermore, the fluidizer has a strip-shaped structure.

[0017] Furthermore, the branch pipe is connected to the fluidizer via threads or flanges.

[0018] Furthermore, the gas distribution platform is a horizontal cylindrical structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. By setting up a surrounding flow aid pipeline on the packaging silo and installing a fluidizer inside the packaging silo, the material enters the packaging silo through the feed inlet. When the material level reaches the process control index, the Roots blower is turned on to compress and deliver clean air filtered by the air filter to the gas distribution station. After the gas distribution station distributes the gas to the flow aid pipeline, it is discharged through the branch pipe connected to the flow aid pipeline and finally through the fluidizer. The material is always in a fluidized state.

[0021] 2. By installing a vibrating motor in the conical structure of the packaging bin and controlling its start and stop via a time relay, the vibration magnitude of the vibrating motor is achieved by adjusting the angle of the pendulum, ensuring that the material does not stick to the bin wall.

[0022] 3. By setting pressure gauges on the gas distribution platform and adjusting the valve openings on the flow aid lines according to the number of fluidizers, the gas flow rate can be observed to ensure uniform gas distribution and keep the material in a stable and balanced flow state inside the cone bottom of the packaging silo.

[0023] 4. By adding a compressed air purging pipeline to the discharge port of the packaging silo, the material is ensured to flow smoothly at the discharge port. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a lightweight calcium carbonate packaging system, including: a packaging chamber 1, a packaging machine 19 and an air pipeline 8. The top of the packaging chamber 1 is equipped with a dust collector 2 and a feed inlet 3, the bottom of the packaging chamber 1 is equipped with a vibration motor 15, the bottom of the packaging chamber 1 has a conical structure, and the end of the conical structure of the packaging chamber 1 is equipped with a discharge port 21.

[0030] The dust collector 2 is a bag filter dust collector. The dust collector 2 can be a cylindrical structure or a cuboid structure. It is installed at the top center of the packaging bin 1. In this embodiment of the utility model, the dust collector 2 is a cylindrical structure.

[0031] The feed inlet 3 is located at the top of the packaging chamber 1. It is generally fed by connecting to the feed pipeline. The feed inlet 3 is located on the outside of the dust collector 2.

[0032] The outer wall of the tapered structure at the bottom of the packaging chamber 1 is equipped with a steel base (not marked). The vibration motor 15 is generally fixed to the steel base at the bottom of the packaging chamber 1 by bolts. There are no requirements for the structure of the steel base, as long as it can stably install the vibration motor 15.

[0033] The packaging machine 19 is connected to the bottom discharge port 21 of the packaging chamber 1 via a short connecting pipe 17. A star-shaped feeder 18 is mounted on the short connecting pipe 17, and a compressed air purging line 16 is connected to the short connecting pipe 17 between the discharge port 21 and the star-shaped feeder 18. The compressed air purging line 16 is fixed to the short connecting pipe 17 by oblique welding from top to bottom. The angle between the compressed air purging line 16 and the short connecting pipe 17 is 30° to 60°, preferably 45° to 60°. In this embodiment of the invention, the angle between the compressed air purging line 16 and the short connecting pipe 17 is set at 45°.

[0034] The star-shaped feeder 18, also known as a star-shaped unloader, is a common device on the market. In the embodiments of this utility model, the structure is not limited.

[0035] Air line 8 is sequentially connected to air filter 4, Roots blower 5, and gas distribution platform 9. Gas distribution platform 9 distributes multiple flow aid lines 10, which surround the outer periphery of the conical structure at the bottom of packaging chamber 1 from top to bottom. The flow aid lines 10 are placed parallel and coaxially, with their central axis coinciding with the central axis of packaging chamber 1. Each flow aid line 10 has multiple branch pipes 20, which are evenly distributed along the outer periphery of packaging chamber 1, inserted into the conical structure of packaging chamber 1, and welded to the packaging chamber 1. Each branch pipe 20 is connected to a fluidizer 14 at its end. In this embodiment, the flow aid lines 10 have multiple branch pipes 20 evenly distributed at equal intervals. One end of each branch pipe 20 is inserted into the conical part of packaging chamber 1, and the other end is connected to a fluidizer 14. The number of branch pipes 20 depends on the size of the packaging chamber 1. It can be 3, 4, 5, 6, 7, 8, 9, 10...20, or even more. The spacing between two adjacent branch pipes 20 is also adjusted according to the size of the packaging chamber 1.

[0036] Air filter 4 and Roots blower 5 are commonly used devices on the market. Air filter 4 uses a filter screen to intercept dust, particulate matter, oil mist and other impurities in the air, preventing them from entering the interior of Roots blower 5 and avoiding damage to key components such as impeller and bearing due to wear or corrosion.

[0037] As a power source, the Roots blower 5 provides a stable airflow to the pipeline system. During operation, the air volume of the Roots blower 5 matches the exhaust volume of the dust collector 2 to ensure normal pressure inside the packaging silo 1.

[0038] The height of the installation position of the vibration motor 15 from the end of the conical structure of the packaging chamber 1 is 1 / 4 to 1 / 2 of the total height of the conical structure of the packaging chamber 1. In a preferred embodiment of this utility model, the height of the installation position of the vibration motor 15 from the end of the conical structure of the packaging chamber 1 is 1 / 3 of the total height of the conical structure of the packaging chamber 1. In other embodiments of this utility model, the height of the installation position of the vibration motor 15 from the end of the conical structure of the packaging chamber 1 is any height between 1 / 4 and 1 / 2 of the total height of the conical structure of the packaging chamber 1.

[0039] The operation of the vibration motor 15 is controlled by a time relay.

[0040] The air pipeline 8 is equipped with a safety valve 6 and a check valve 7. Safety valve 6 and check valve 7 are general-purpose safety valves and check valves, and no special requirements are made in this embodiment of the invention. Check valve 7 is located downstream of the Roots blower 5, and safety valve 6 is located between the Roots blower 5 and check valve 7. By installing safety valve 6, when the pressure in the pipeline exceeds a set value, safety valve 6 automatically opens and discharges excess medium, and closes after the pressure returns to normal, preventing the system from bursting or leaking due to overpressure. By installing check valve 7, backflow of gas can be prevented, protecting equipment safety.

[0041] The gas distribution platform 9 is a horizontal cylindrical structure used for gas distribution and is equipped with a pressure gauge 11 for observing the air pressure inside the gas distribution platform 9. Specifically, compressed air filtered by the air filter 4 is delivered to the gas distribution platform 9 via the air pipeline 8. The gas distribution platform 9 distributes the compressed air to multiple flow-aiding pipelines 10, thus playing a gas distribution role. One end of each flow-aiding pipeline 10 is fixed to the gas distribution platform 9 by flange connection or welding. In this embodiment of the present invention, there are three flow-aiding pipelines 10, which are evenly distributed from top to bottom around the outer periphery of the conical structure of the packaging chamber 1 at the same height and fixed to the packaging chamber 1 via branch pipes 20. In other embodiments of the present invention, the number of flow-aiding pipelines 10 may be 2, 4, 5, 6, 7, 8, 9, 10 or more, and the number can be appropriately adjusted according to the size of the packaging chamber 1. Normally, multiple flow aids 10 are evenly distributed from top to bottom around the outer periphery of the conical structure of the packaging chamber 1 at the same height, and are fixed to the packaging chamber 1 through branch pipes 20.

[0042] Each flow aid line 10 is equipped with a valve 12 and a flow meter 13. By setting the flow meter 13, the flow rate of compressed air in the flow aid line 10 can be monitored in real time, providing data support for process control. By setting the valve 12, the flow rate of compressed air can be precisely controlled by adjusting the opening of the valve 12. When the flow meter 13 on the flow aid line 10 detects a change in flow rate, the opening of the valve 12 is adjusted to match the requirements.

[0043] The fluidizer 14 has a strip-shaped structure and is connected to the branch pipe 20 via threads or flanges. In this embodiment of the invention, the branch pipe 20 is connected to the fluidizer 14 via threads. The valves 12 on the flow aid line 10 are adjusted according to the number of fluidizers 14 in each layer, and the gas flow rate is observed to ensure the uniformity of gas distribution, so that the material is in a stable and balanced flow state inside the conical part of the packaging chamber 1.

[0044] Working Principle: Finished light calcium carbonate enters packaging silo 1 through inlet 3. When the material level reaches the process control target, the Roots blower 5 is started, delivering clean compressed air filtered by air filter 4 to gas distribution platform 9. Gas distribution platform 9 distributes the air to multiple flow aid lines 10, which then enter the packaging silo 1 through branch pipes 20 connected to the flow aid lines 10, finally discharging through fluidizer 14. The material remains in a fluidized state throughout. By observing the pressure on pressure gauge 11 on gas distribution platform 9, valves 12 on flow aid lines 10 are adjusted according to the number of fluidizers 14 in each layer, and the gas flow rate is observed to ensure uniform gas distribution, maintaining a stable and balanced flow state for the material within the conical structure of packaging silo 1. The airflow of Roots blower 5 is matched with the exhaust volume of dust collector 2 to maintain normal pressure inside packaging silo 1. To further prevent material from adhering to the walls of packaging silo 1, the vibration motor 15 installed on the outer wall of the bottom conical structure of packaging silo 1 is activated. The vibration magnitude of the vibration motor 15 is adjusted by changing the pendulum angle, and its start and stop are controlled by a time relay. When the material is conveyed to the short pipe 17, the compressed air purging line 16 is turned on to purge the material. The compressed air purging line 16 is in a slightly open state. The fluidized material enters the packaging machine 19 for packaging through the star feeder 18.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
