Description

Technical Field

[0001] This utility model relates to the field of fine powder ton bag conveying technology, specifically a positive pressure conveying device for feeding fine powder ton bags. Background Technology

[0002] In the fields of chemical engineering, pharmaceuticals, food, new energy, and building materials, fine powdery materials such as calcium carbonate powder, pharmaceutical raw materials, milk powder, and cathode material powders are produced and processed on a large scale. The ton bag, also known as a bulk container or FIBC, serves as the core carrier for material storage, transfer, and feeding, acting as a standard packaging unit. These materials typically have fine particle sizes, often in the micron or even nanometer range, low bulk density, and are prone to dust generation, moisture absorption, and clumping, or possess certain corrosive and toxic properties. The ton bag is used for feeding and conveying materials from the ton bag to subsequent production equipment such as reactors, mixers, and silos.

[0003] While existing technologies can achieve the conveying of fine powder in ton bags, traditional semi-mechanized or manual assistance methods are still widely used. During the feeding process, due to the dust-generating nature of fine powder materials, the feeding process lacks a closed system. When the material falls from the ton bag opening, it mixes violently with the air, generating a large amount of dust and causing pollution. Furthermore, the lack of an auxiliary feeding structure makes it easy for the ton bag to become clogged when it enters the hopper, thus affecting normal feeding and resulting in poor overall practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a positive pressure conveying device for feeding fine powder ton bags. It can effectively solve the problems in the prior art, where the feeding process is not closed due to the dust-generating nature of fine powder materials. When the material falls from the ton bag opening, it mixes violently with the air, generating a large amount of dust and causing pollution. In addition, the lack of an auxiliary feeding structure makes it easy for the ton bag to become blocked when it enters the hopper, thus affecting normal feeding and resulting in poor overall practicality.

[0005] The technical solution adopted by this utility model is: a positive pressure conveying device for feeding fine powder ton bags, including a casing, a bag-unloading frame and a distribution pipe. An oscillation component is provided at the inner edge of the casing. An inner material pipe, a middle material pipe and an outer material pipe are provided at the end of the bag-unloading frame away from the oscillation component. The inner material pipe, the middle material pipe and the outer material pipe are interconnected with the distribution pipe. A blower is provided at the other end of the distribution pipe away from the casing. A dust collector is fixedly installed at the end of the blower away from the distribution pipe. A magnetic suction filter is provided at the outlet of the dust collector. The oscillation assembly includes a ton bag, a fixing plate, and a limiting frame. The fixing plate is fixedly installed on the machine housing, and a slider is fixedly installed on the outer edge of the ton bag.

[0006] Preferably, a pallet is fixedly installed at the outer edge, and a fixing pipe is provided at the bottom of the pallet. The fixing pipe is interconnected with the ton bag. There are two identical sets of pallets and fixing pipes, and each set has two identical pallets and fixing pipes. The two sets of pallets and fixing pipes are symmetrically distributed about the center line of the limiting frame.

[0007] The above technical solution, through the design of two sets of symmetrical trays, allows scattered fine powder to fall into the trays, and then be guided into the ton bag through the fixed pipe, thus avoiding scattering during the feeding process. In addition, the fixed pipe is interconnected with the ton bag, which can guide the fine powder to fall into the subsequent material pipe, reducing the accumulation of fine powder at the outlet of the ton bag.

[0008] Preferably, an oscillator is fixedly installed at one end of the slider near the fixed plate, and the slider and the fixed plate are slidably connected.

[0009] Through the above technical solution, the design of the oscillator can drive the slider to slide along the fixed plate, thereby making the ton bag oscillate synchronously. The vibration can loosen the fine powder that is easy to clump inside the ton bag, preventing clumping and clogging of the ton bag outlet or material pipe. The sliding cooperation between the slider and the fixed plate increases the oscillation stroke, so that the fine powder inside the ton bag falls evenly.

[0010] Preferably, a viewing window is provided at the outer edge of the bag opening frame, an outer material discharge pipe one is provided at the outer edge of the inner material pipe, an outer material discharge pipe two is provided at the outer edge of the outer material discharge pipe one, and the outer material discharge pipe one and the outer material discharge pipe two are interconnected with the material distribution pipe.

[0011] The above technical solution allows staff to observe the feeding status of fine powder in the bag-unloading frame in real time through a viewing window, enabling timely detection and handling of abnormalities. The outer material discharge pipes 1 and 2 of the inner material pipe are interconnected with the distribution pipe, which can divert the fine powder to different conveying channels.

[0012] Preferably, a material discharge pipe one is provided at the outer edge of the material pipe, and a material discharge pipe two is provided at the end of the material discharge pipe one away from the material pipe, and the material pipe, the material discharge pipe one and the material discharge pipe two are interconnected.

[0013] Through the above technical solution, an independent conveying channel is formed by the interconnected structure of the middle material pipe and the two-stage discharge pipe, which can be distinguished from the channels of the inner material pipe and the outer material pipe, so as to realize the classified conveying of different batches and different types of fine powder.

[0014] Preferably, an inner material outlet pipe is provided at one end of the outer material pipe near the inner material outlet pipe, a blower is provided at one end of the inner material outlet pipe, and a filter pipe is provided at the end of the inner material outlet pipe away from the inner material outlet pipe.

[0015] Through the above technical solution, by designing a blower to inject auxiliary positive pressure air into the material distribution pipe, the airflow power in the outer material pipe and the inner material discharge pipe can be enhanced, so that the fine powder does not settle during long-distance transportation.

[0016] Preferably, the material distribution pipe and the filter pipe are interconnected, a mounting frame is fixedly installed on the outer edge of the dust collector, a feeding frame is fixedly installed on the casing, and a feeding groove is opened on the inner edge of the feeding frame.

[0017] Through the above technical solution, the material distribution pipe and the filter pipe are interconnected, so that the fine powder is initially filtered before entering the main conveying channel, thereby improving the cleanliness of the conveying. The dust collector can collect the fine powder dust that escapes during the conveying process, avoiding dust pollution of the workshop environment. At the same time, the recovered fine powder can be re-entered into the conveying channel, improving the utilization rate of raw materials.

[0018] Compared with the prior art, this utility model provides a positive pressure conveying device for feeding fine powder in ton bags, which has the following beneficial effects: 1. This fine powder ton bag feeding positive pressure conveying device, through the interconnection of the distribution pipe and the filter pipe, allows the fine powder to be initially filtered before entering the main conveying channel, improving the cleanliness of the conveying. The dust collector can collect the fine powder dust that escapes during the conveying process, avoiding dust pollution of the workshop environment. Through the design of two sets of symmetrical trays, the scattered fine powder falls into the trays, and then the fine powder is guided into the ton bag through the fixed pipe, avoiding the scattering during the feeding process. In addition, the fixed pipe is interconnected with the ton bag, which can guide the fine powder to fall into the subsequent material pipe, reducing the accumulation of fine powder at the outlet of the ton bag. 2. This fine powder ton bag feeding positive pressure conveying device, through the design of the vibrator, can drive the slider to slide along the fixed plate, thereby making the ton bag vibrate synchronously. The vibration can loosen the fine powder that is prone to caking in the ton bag, avoiding caking and clogging of the ton bag outlet or material pipe. The sliding cooperation between the slider and the fixed plate increases the vibration stroke, so that the fine powder in the ton bag falls evenly. The viewing window allows the staff to observe the feeding status of the fine powder in the bag opening frame in real time, and promptly detect and deal with abnormalities. The outer material outlet pipe 1 and outer material outlet pipe 2 of the inner material pipe are interconnected with the distribution pipe, which can divert the fine powder to different conveying channels.

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.

[0022] Example 1: As Figure 1-7 As shown, the present invention provides a positive pressure conveying device for feeding fine powder ton bags, including a housing 1, a bag-opening frame 5, and a distribution pipe 14. An oscillation component 4 is provided at the inner edge of the housing 1. An inner material pipe 7, a middle material pipe 8, and an outer material pipe 9 are provided at the end of the bag-opening frame 5 away from the oscillation component 4. The inner material pipe 7, the middle material pipe 8, and the outer material pipe 9 are interconnected with the distribution pipe 14.

The fixing plate 402 is fixedly installed on the machine housing 1, and a slider 403 is fixedly installed on the outer edge of the ton bag 401.

[0023] Specifically, a tray 406 is fixedly installed at the outer edge, and a fixing pipe 407 is provided at the bottom of the tray 406. The fixing pipe 407 is interconnected with the ton bag 401. Two identical sets of trays 406 and fixing pipes 407 are provided in each set, and two identical sets of trays 406 and fixing pipes 407 are provided in each set. The two trays 406 and fixing pipes 407 are symmetrically distributed about the center line of the limiting frame 405. The advantage is that the design of two sets of symmetrical trays 406 allows scattered fine powder to fall into the trays 406, and then be guided into the ton bag 401 through the fixing pipe 407, avoiding scattering during the feeding process. In addition, the connection between the fixing pipe 407 and the ton bag 401 can guide the fine powder to fall directionally into the subsequent feed pipe, reducing the accumulation of fine powder at the outlet of the ton bag 401.

[0024] Specifically, a vibrator 404 is fixedly installed at one end of the slider 403 near the fixed plate 402. The slider 403 and the fixed plate 402 are slidably connected. The advantage is that, through the design of the vibrator 404, the slider 403 can be driven to slide along the fixed plate 402, thereby making the ton bag 401 vibrate synchronously. The vibration can loosen the fine powder that is easy to clump inside the ton bag 401, and prevent clumps from clogging the outlet or material pipe of the ton bag 401. The sliding cooperation between the slider 403 and the fixed plate 402 increases the oscillation stroke, so that the fine powder inside the ton bag 401 falls evenly.

[0025] Specifically, a viewing window 6 is provided at the outer edge of the unloading frame 5, an outer material discharge pipe 10 is provided at the outer edge of the inner material pipe 7, and an outer material discharge pipe 21 is provided at the outer edge of the outer material discharge pipe 10. The outer material discharge pipe 10 and the outer material discharge pipe 211 are interconnected with the distribution pipe 14. The advantage is that the viewing window 6 allows the staff to observe the feeding status of fine powder in the unloading frame 5 in real time, and to promptly detect and handle abnormalities. The outer material discharge pipe 10 and the outer material discharge pipe 211 of the inner material pipe 7 are interconnected with the distribution pipe 14, which can divert the fine powder to different conveying channels.

[0026] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, a material discharge pipe 12 is provided at the outer edge of the material pipe 8, and a material discharge pipe 23 is provided at the end of the material discharge pipe 12 away from the material pipe 8. The material pipe 8, the material discharge pipe 12 and the material discharge pipe 23 are interconnected. The advantage is that the interconnection structure between the material pipe 8 and the two-stage discharge pipes forms an independent conveying channel that can be distinguished from the channels of the inner material pipe 7 and the outer material pipe 9, so as to realize the classified conveying of different batches and different types of fine powder.

[0028] Specifically, an inner material discharge pipe 16 is provided at one end of the outer material pipe 9 near the inner material discharge pipe 14, a blower 15 is provided at one end of the inner material discharge pipe 14, and a filter pipe 17 is provided at the other end of the inner material discharge pipe 16. The advantage is that by designing the blower 15, auxiliary positive pressure air is injected into the inner material discharge pipe 14, which can enhance the airflow power in the outer material pipe 9 and the inner material discharge pipe 16, so that the fine powder does not settle during long-distance transportation.

[0029] Specifically, the distribution pipe 14 and the filter pipe 17 are interconnected. A mounting bracket 20 is fixedly installed on the outer edge of the dust collector 19. A feed frame 2 is fixedly installed on the casing 1. A feed trough 3 is opened on the inner edge of the feed frame 2. The advantage is that by connecting the distribution pipe 14 and the filter pipe 17, the fine powder can be pre-filtered before entering the main conveying channel, which improves the cleanliness of the conveying. In addition, the dust collector 19 can collect the fine powder dust that escapes during the conveying process, avoiding dust pollution of the workshop environment. At the same time, the recovered fine powder can be re-entered into the conveying channel, which improves the utilization rate of raw materials.

[0030] Working Principle: During use, the design of two sets of symmetrical trays 406 allows scattered fine powder to fall into the trays 406, and then guides the fine powder into the ton bag 401 through the fixed pipe 407, preventing it from scattering during the feeding process. The fixed pipe 407 is interconnected with the ton bag 401, guiding the fine powder directionally into the subsequent feed pipe, reducing the accumulation of fine powder at the outlet of the ton bag 401. The design of the vibrator 404 drives the slider 403 to slide along the fixed plate 402, thereby causing the ton bag 401 to vibrate synchronously. The vibration loosens the easily agglomerated fine powder inside the ton bag 401, preventing clumping and blockage of the outlet or feed pipe. The sliding cooperation between the slider 403 and the fixed plate 402 increases the vibration stroke, ensuring the fine powder falls evenly inside the ton bag 401. The viewing window 6 allows operators to observe the feeding status of the fine powder in the unloading frame 5 in real time and make timely adjustments. Anomalies are detected and addressed. The outer material discharge pipes 10 and 11 of the inner material pipe 7 are interconnected with the distribution pipe 14, which can divert fine powder to different conveying channels. The interconnection structure between the middle material pipe 8 and the two-stage discharge pipes forms an independent conveying channel that can be distinguished from the channels of the inner material pipe 7 and the outer material pipe 9, realizing the classified conveying of different batches and different types of fine powder. Through the design of the blower 15, auxiliary positive pressure air is injected into the distribution pipe 14, which can enhance the airflow power in the outer material pipe 9 and the inner material discharge pipe 16, so that the fine powder does not settle during long-distance conveying. The distribution pipe 14 is interconnected with the filter pipe 17, so that the fine powder enters the main conveying channel after preliminary filtration, improving the cleanliness of the conveying. The dust collector 19 can collect the fine powder dust that escapes during the conveying process, avoiding dust pollution of the workshop environment. At the same time, the recovered fine powder can be re-entered into the conveying channel, improving the utilization rate of raw materials.
