Description

Technical Field

[0001] This invention relates to the field of powdered material filling technology, and in particular to a metering filling and dust prevention device. Background Technology

[0002] The metering and filling device uses gravity feeding to add material to the filling hopper. During the feeding process, the height difference of the filling device causes impact when feeding powdery materials, especially when the material is heavy and the height difference is large, the impact is particularly noticeable. Simultaneously, the powdery material generates a large amount of dust, which disperses over a wide area and for a long time, affecting the overall weighing and feeding time, reducing weighing accuracy, and the potential for safety accidents due to the scattering of highly sensitive powdery materials. Therefore, it is necessary to design a dust prevention device for metering and filling powdery materials to adjust the feeding height, reduce the dust dispersion range, and prevent dust scattering, thereby improving weighing and feeding efficiency, ensuring weighing accuracy, and preventing safety accidents.

[0003] Currently, powdered material filling is typically done manually, especially for highly sensitive powders. After manual weighing, the material is poured into a filling hopper, either manually or with a assisted mechanism. Dust is removed by dust collection equipment, and any spilled material is washed away. Powdered material filling can be achieved manually or semi-automatically.

[0004] However, manual operation makes it difficult to effectively control dust and scattering of powdery materials. Dust collection equipment cannot guarantee complete dust removal in open spaces, which affects the environment and can cause harm to human health. Excessive dust accumulation at distant locations after removal also requires more processing steps. Scattered powdery materials need to be swept and recycled, especially highly sensitive powdery materials, which cannot be rubbed or squeezed and can only be washed with water, which is time-consuming, labor-intensive, and cannot guarantee thorough cleaning. After weighing, dust and scattering of powdery materials result in weight loss and compromised accuracy. Furthermore, safety is compromised when manually handling highly sensitive powdery materials.

[0005] In the existing technology, there are also semi-automatic or automatic equipment for weighing and filling powdered materials. After automatic weighing, the powder is poured into the filling bucket, or the material is weighed and discharged at the same time. These equipment are usually equipped with lifting mechanisms, vibration devices, dust collection equipment and washing equipment, but none of them are equipped with reliable metering, filling and discharging devices.

[0006] However, during the filling process, the height difference between the filling hopper and the discharge port causes the material to fall, resulting in a lot of dust. The equipment is equipped with a lifting mechanism or vibration device, and when automatically weighing and filling, it is difficult to seal the discharge port, causing dust to fall outside the filling hopper during the filling process. The dust collection equipment is noisy and the suction power is difficult to adjust. Excessive suction power will cause material weight loss, while insufficient suction power will not achieve the desired dust removal effect. Excessive dust or scattered material cannot be completely cleaned by the dust collection or washing equipment, and further processing is required at a distance. In particular, highly sensitive powdery materials, when a large amount accumulates around the equipment or in the dust collection pipe, are very dangerous and can easily cause safety accidents. Summary of the Invention

[0007] In view of the above problems, the present invention provides a metering filling and discharging dust prevention device for overcoming or at least partially solving the above problems.

[0013] When the dust cover is connected to the loading hopper, during the feeding process of the vibrating feeder, the anti-static sealing flexible connection is used to prevent dust from leaking out from the upper port and to prevent the feeding hopper from colliding with the upper port and generating static electricity. The inner dust baffle is used to prevent the dust removal system from sucking away the material falling into the loading hopper when the dust removal system is working. The dust removal system is used to suck away the dust that drifts outside the inner dust baffle through the dust extraction pipe and the dust extraction port.

[0018] Preferably, the inlet is connected to the feeding end of the filling body via a hose passing through the connecting plate.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This invention provides a metering, filling, and dust prevention device, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the device may include:

[0032] Feeding hopper 1, the feeding hopper 1 includes a feed inlet and a discharge outlet;

[0033] Vibrating feeder 2, which is connected to the feeding hopper 1;

[0034] The dust cover 3 has an upper port 31 at its upper end, which is connected to the discharge port via an anti-static sealing flexible connection 4; the bottom of the dust cover 3 has an inner dust baffle 32 extending circumferentially therefrom, the inner diameter of which is smaller than the diameter of the opening of the filling barrel 7; the side of the dust cover 3 has a dust extraction port 33, which is used to connect to the dust extraction pipe 5 of the dust removal system.

[0035] When the dust cover 3 is connected to the loading hopper 7, during the feeding process of the vibrating feeder 2, the anti-static sealing flexible connection 4 is used to prevent dust from leaking out from the upper port 31, and at the same time to prevent the feeding hopper 1 from colliding with the upper port 31 and generating static electricity. The inner dust baffle 32 is used to prevent the dust removal system from sucking away the material falling into the loading hopper 7 when the dust removal system is working. The dust removal system is used to suck away the dust that drifts outside the inner dust baffle 32 through the dust extraction pipe 5 and the dust extraction port 33.

[0036] The metering and filling dustproof device provided in this application addresses the problems of high dust levels, low efficiency due to material scattering, weight loss, difficulty in ensuring accuracy, and cleaning difficulties in the current process of weighing and filling powdery materials, as well as the high safety hazards associated with highly sensitive powdery materials. It utilizes adjustable hopper drop height and angle via pull ropes and supports to mitigate impact and reduce dust generation; employs anti-static flexible connections to seal the material inlet, preventing material scattering and drifting; and uses internal baffles to separate material from dust, facilitating rapid dust removal in conjunction with dust collection equipment. This device improves the efficiency of weighing and filling powdery materials, ensures weighing accuracy, and resolves the safety hazards associated with powdery materials, especially highly sensitive ones.

[0037] The dust cover 3 features an open-top design with a dust baffle plate inside the opening, allowing materials to enter the loading hopper 7 within the dust-proof space, effectively reducing dust dispersion. A dust extraction pipe 5 is located on the right side of the dust cover 3 to remove floating dust, thus achieving a good dust-proof effect.

[0038] The anti-static sealing flexible connector 4 is used to connect the lower edge of the feed hopper to the upper port 31 of the dust cover. It is made of special material to prevent static electricity from friction. When the vibrating feeder 2 is working, it drives the feed hopper 1 to swing. The flexible connector can effectively prevent the feed hopper from colliding with the dust cover 3. The upper and lower parts fit tightly, and the sealing effect is significant.

[0039] To facilitate the installation of the dust cover 3, this embodiment of the application may also provide a filling body support 6, wherein the dust cover 3 is connected to the filling body support 6.

[0040] Furthermore, the filling main support 6 includes a connecting plate 61, and the feeding hopper 1 is connected to the connecting plate 61 by a plurality of stainless steel cables 62, which are used to make the feeding hopper 1 tilted.

[0041] In a specific implementation, the embodiments of this application can provide that the length of the stainless steel cable 62 is adjustable, so as to change a portion of the length of the stainless steel cable 62 to adjust the tilt angle of the feeding hopper 1, thereby achieving the purpose of adjusting the discharge flow rate of the feeding hopper.

[0042] Furthermore, the stainless steel cable 62 is connected to the connecting plate 61 by a threaded connection.

[0043] To facilitate connection with the main feeding end, this embodiment of the application may also provide that the inlet is connected to the feeding end of the filling body via a hose passing through the connecting plate 61.

[0044] Stainless steel cable 62 is fixed to the filling main support 6 via a threaded connection. The cable retraction adjusts the tilt angle of the feeding hopper 1, thereby adjusting the flow rate of the powdered material during the feeding process. This provides buffering protection for the material and reduces dust spillage when the material enters the filling hopper 7. The filling main support 6 can be height-adjusted to match the tilt angle of the inclined feeding hopper 1, and the support is welded to the dust cover 3, effectively supporting and stabilizing the entire device.

[0045] The material enters the feeding hopper 1 through the filling body, and the vibrating feeder 2 is started to feed the material. The stainless steel cable 62 is installed on the filling body support 6 for height fine adjustment. The position is adjusted by the adjustable filling body support 6 so that the material enters the filling barrel 7 in the dustproof space.

[0046] The following section provides a detailed description of the metering, filling, and dust prevention device provided in this application, taking the inclined state of the feeding hopper 1 as an example.

[0047] The components include an inclined feeding hopper 1, an adjustable stainless steel cable 62, an adjustable filling main support 6, a vibrating feeder 2, a dust cover 3, and an anti-static sealed flexible connection 4. The inclined feeding hopper 1, the adjustable stainless steel cable 62, and the vibrating feeder 2 form the feeding section. The dust cover 3 and the adjustable filling main support 6 form the receiving section. The anti-static sealed flexible connection 4 connects the two parts via a clamp.

[0048] The feeding hopper 1 is fixed to the main filling support 6 via a threaded connection. The tilt angle of the feeding hopper 1 is adjusted by cable retraction, thereby adjusting the flow speed of the powdered material during the feeding process. This provides a buffering and protection effect for the material feeding and reduces the ejection of powder when the material enters the filling hopper 7. The height can be adjusted to match the tilt angle of the inclined feeding hopper 1, and the support is welded to the dust cover 3, which can effectively support and stabilize the entire device.

[0049] The dust cover 3 adopts an open-top design, with an inner dust baffle 32 added inside the opening, allowing materials to enter the loading hopper 7 within the dust-proof space, effectively reducing dust diffusion. A dust extraction pipe 5 is located on the right side of the dust cover 3 to remove floating dust, thus achieving a good dust-proof effect.

[0050] The feed hopper outlet is connected to the dust cover 3 discharge port, and a special material is used to prevent friction and static electricity. When the vibrating feeder 2 is working, it drives the feed hopper 1 to swing. The flexible connection can effectively prevent the feed hopper and dust cover 3 from colliding. The upper and lower parts fit tightly, and the sealing effect is significant.

[0051] Material enters the inclined feeding hopper 1 through the filling body. After the filling bucket 7 is in place, it is pushed into the dust cover 3 by the lifting device. When discharging, the vibrating feeder 2 is in the open state, and the inclined feeding hopper 1 vibrates with the feeder 2. At this time, the anti-static sealing flexible connection 4 between the inclined feeding hopper 1 and the dust cover 3 at the discharge port has good flexibility. During the vibration, the clamp is tightly attached to the connection part, preventing dust from leaking out from the upper port 31 of the dust cover. At the same time, it protects the lower edge of the feeding hopper 1 and avoids collision with the upper port 31 of the dust cover to avoid static electricity.

[0052] To improve dust prevention and reduce unnecessary dust loss, the bottom of the dust cover 3 is designed with an inner dust baffle plate, the diameter of which is slightly smaller than that of the loading hopper 7. This prevents the dust removal system from drawing away the falling material due to excessive wind force during the feeding process. At the same time, it forms a dust-proof space with the outer wall of the dust cover 3, and promptly removes a small amount of dust that falls into the loading hopper 7 and then drifts out through the inner dust baffle plate from the dust extraction port 33.

[0053] During the material feeding process, the dust removal system is activated, and the dust is drawn away through the dust extraction pipe 5 into the wet dust removal device to achieve the purpose of dust prevention.

[0054] In summary, the metering and filling dust control device provided in this application solves the problems of high dust levels, low efficiency due to material spillage, weight loss, difficulty in ensuring accuracy, and cleaning difficulties, as well as high safety hazards associated with highly sensitive materials, that previously occurred during the metering and filling process when operated manually or on other automated equipment. It provides a clean environment on-site and plays a significant role in protecting materials from explosion. After debugging and actual use, it can operate continuously and stably, and the overall dust control effect of the device is remarkable.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0056] As can be seen from the above description of the embodiments, those skilled in the art can clearly understand that this application can be implemented by means of software plus necessary general-purpose hardware platforms.
