Description

Technical Field

[0001] This utility model relates to the field of supply device technology, and in particular to a dust feeding device. Background Technology

[0002] In the copper smelting process, some fumes are used as raw materials in production. The existing feeding equipment mainly includes a fume storage silo 001 and a belt conveyor 002. The fumes are stored in the fume storage silo 001. The bottom of the fume storage silo 001 is connected to the conveyor through a discharge pipe. The discharge pipe is controlled by a valve 003. When feeding is needed, the valve 003 is opened, and the fumes fall vertically from the fume storage silo 001 through the discharge pipe onto the belt conveyor 002. The belt conveyor 002 then transports the fumes into the relevant equipment.

[0003] like Figure 1 As shown, to ensure the smooth transfer of dust to the belt conveyor 002, there is currently a large gap between the lower end of the discharge pipe and the working surface of the belt conveyor 002. Under normal operating conditions, the lower end of the discharge pipe and the working surface of the belt conveyor 002 are sealed by the dust material. Since the dust is dry and consists of tiny particles, it has great fluidity. When there is no material on the belt conveyor 002 and the valve 003 is opened to start feeding, the dust will diffuse outward from the gap between the belt conveyor 002 and the discharge pipe, causing the dust to leak out of the belt conveyor 002. This results in a large amount of dust being generated around the belt conveyor 002, polluting the surrounding environment, making cleaning difficult, and wasting dust. Furthermore, the current feeding method mainly controls the amount of dust fed by calculating the operating speed of the belt conveyor 002, which is not precise enough. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this utility model provides a dust feeding device, aiming to solve the environmental pollution problem caused by dust overflow during feeding.

[0005] The aforementioned dust feeding device includes a feed hopper, a storage bin, a belt scale, and a bag filter.

[0006] The storage bin is equipped with a feeding hopper at the top, and the feeding hopper has a bag opening structure inside; a belt scale is installed below the storage bin, and the belt scale is covered with a dust cover.

[0007] The bottom of the storage bin is equipped with a discharge pipe, which is equipped with a valve. The lower end of the discharge pipe extends into the dust cover and is equipped with a rubber sealing sheet. The lower end of the rubber sealing sheet abuts against the working surface of the belt scale to form a seal. Three rubber sealing sheets are provided, which are located on the front, rear, and right sides of the discharge pipe, respectively.

[0008] A bag filter is provided on one side of the feed hopper. The feed end of the bag filter is connected to the air outlet of the dust collection fan through a pipe. The air inlet of the dust collection fan is connected to the top of the storage bin through a pipe.

[0009] In some designs, the rubber sealing sheet has oblong holes distributed vertically, and the feed tube has connecting holes. The connecting bolt passes through the connecting holes and the oblong holes in sequence and is then threaded into the locking nut, thereby firmly connecting the rubber sealing sheet and the feed tube.

[0010] In some designs, the rubber sealing plates on the front and rear sides extend forward a distance along the conveying direction of the belt scale.

[0011] In some embodiments, the bag-opening structure includes at least two bag-opening blades, the tops of all the bag-opening blades are connected to each other, the lower ends of the bag-opening blades are fixedly connected to the feed hopper, and the bag-opening blades are inclined.

[0012] In some designs, the bag-opening knife is provided in three parts.

[0013] In some designs, a maintenance platform is provided at the bottom of the storage silo, the bag filter is mounted on the maintenance platform, and the ash discharge port of the bag filter is connected to the storage silo via a pipe.

[0014] The technical solution provided by this utility model can include the following beneficial effects:

[0015] This application seals the gap between the feeding pipe and the belt scale by setting a rubber sealing gasket at the lower end of the feeding pipe, so that the dust can only diffuse in the conveying direction of the belt scale, effectively preventing the dust from overflowing during feeding. At the same time, the belt scale accurately measures the amount of dust added, effectively ensuring the accuracy of the dust addition.

[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the present invention. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0026] Please see Figure 2 This application provides a dust feeding device, including a feeding hopper 1, a storage bin 2, a belt scale 3, and a bag filter 4; the top of the storage bin 2 is provided with a feeding hopper 1, which is conical in shape to facilitate the feeding of dust into the storage bin 2; the feeding hopper 1 is provided with a bag opening structure 9, which is used to tear the bag containing the dust to release the dust inside the bag; the belt scale 3 is provided below the storage bin 2, which is used to weigh the dust to obtain the amount of dust added, and when the belt scale 3 rotates, it transports the dust on it from right to left; the belt scale 3 is covered with a dust cover 5, which is used to prevent dust pollution caused by the diffusion of dust on the belt scale 3.

[0027] The storage bin 2 has a discharge pipe at its bottom, and a valve 6 is provided on the discharge pipe to control the opening and closing of the discharge pipe. The lower end of the discharge pipe extends into the dust cover 5 and is provided with a rubber sealing sheet 7. The lower end of the rubber sealing sheet 7 abuts against the working surface of the belt scale 3 to form a seal. There are three rubber sealing sheets 7, located on the front, rear, and right sides of the discharge pipe, respectively. No rubber sealing sheet 7 is provided on the left side of the discharge pipe to facilitate the conveying of smoke and dust.

[0028] A bag filter 4 is provided on one side of the feeding hopper 1. The feeding end of the bag filter 4 is connected to the air outlet of the dust collection fan 8 through a pipe. The air inlet of the dust collection fan 8 is connected to the top of the storage bin 2 through a pipe.

[0029] During operation, the filter bag containing the dust is hoisted to the top of the feed hopper 1 by a forklift or overhead crane. The filter bag is then slowly lowered into the feed hopper 1. When the filter bag comes into contact with the opening structure 9 inside the feed hopper 1, the bottom of the filter bag is torn by the opening structure 9, and the dust inside the filter bag falls into the feed hopper 1 and then slides into the storage bin 2 for storage. During the process of the dust falling into the storage bin 2, the dust collection fan 8 is activated to suck up the dust generated in the storage bin 2 and guide it into the bag filter dust collector 4 for collection. At the same time, a negative pressure is generated in the storage bin 2 to prevent the dust in the storage bin 2 from overflowing from the feed hopper 1, effectively avoiding the dust pollution problem generated during the process of putting the dust into the storage bin 2.

[0030] When adding smoke dust, valve 6 is opened, and the smoke dust in storage bin 2 falls into belt scale 3 through the discharge pipe. Belt scale 3 then guides the material into the relevant equipment. During this process, belt scale 3 measures the amount of smoke dust added to ensure accuracy. At the moment valve 6 is opened, the smoke dust falls directly from storage bin 2 onto belt scale 3 and diffuses outward. The rubber sealing plate 7 ensures that the smoke dust can only diffuse to the left, i.e., in the direction conveyed by belt scale 3, thus effectively preventing smoke dust overflow and waste. At the same time, it avoids environmental pollution caused by smoke dust overflowing at the moment valve 6 is opened.

[0031] In some specific implementations, such as Figure 3 As shown, the rubber sealing sheet 7 has oblong holes 10 distributed vertically, and the feed pipe has connecting holes. The connecting bolt passes through the connecting holes and the oblong holes 10 in sequence and is screwed into the locking nut, thereby firmly connecting the rubber sealing sheet 7 to the feed pipe. At the same time, when the rubber sealing sheet 7 is worn, the position of the rubber sealing sheet 7 can be adjusted through the oblong holes 10 so that its bottom can always be in contact with the working surface of the belt scale 3, thereby ensuring the sealing performance of the rubber sealing sheet 7 and effectively preventing smoke and dust from overflowing from the gap between the feed pipe and the belt scale 3 when the valve 6 is opened.

[0032] In this embodiment, the rubber sealing sheets 7 on the front and rear sides extend forward a certain distance along the conveying direction of the belt scale 3 to guide the smoke and dust to diffuse in the conveying direction of the belt scale 3, thereby preventing the smoke and dust from flowing back to the right after being discharged from the discharge pipe, and further preventing the smoke and dust from overflowing to the right.

[0033] In this embodiment, as Figure 4As shown, the bag opening structure 9 includes at least two bag opening knives. The tops of all the bag opening knives are connected to each other, and the lower ends of the bag opening knives are fixedly connected to the feed hopper 1. The bag opening knives are inclined to form a conical structure with the blades facing upwards. Thus, when the cloth bag containing dust enters the feed hopper 1, its bottom contacts the tip of the bag opening structure 9, thereby cutting the bottom of the cloth bag to open and unload the bag, effectively improving the efficiency of bag unloading.

[0034] Preferably, the bag-opening knife is provided in three parts, forming a triangular pyramidal structure.

[0035] In this embodiment, as Figure 1 As shown, the bottom of the storage hopper 2 is equipped with a maintenance platform 11. The maintenance platform 11 facilitates the maintenance and inspection of the feed hopper 1 by the staff. The bag filter 4 is installed on the maintenance platform 11, and the ash discharge port of the bag filter 4 is connected to the storage hopper 2 through a pipe. In this way, when the bag filter 4 is unloading ash, the unloaded dust can be directly discharged into the storage hopper 2 through the pipe, eliminating the need for the staff to transfer the unloaded dust, making it more convenient to use.

[0036] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
