Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, and in particular relates to a bag type dust collector. Background Art

[0002] The statements in this section are merely intended to provide background information related to the technical solution of the present application to aid understanding, and they do not necessarily constitute prior art for the technical solution of the present application.

[0003] Copper pyrometallurgy is a pyrometallurgical copper smelting process that removes impurities such as sulfur, iron, lead, zinc, nickel, arsenic, antimony, tin, magnesium and oxygen from crude copper and recycled copper under high-temperature molten conditions to produce pyrometallurgical refined copper. A large amount of flue gas will be generated during the copper pyrometallurgy process, and a dust collector is needed to filter the flue gas. Existing dust collectors still have certain defects when used.

[0004] In the prior art, bag filter is a type of dust collector with high dust removal efficiency. During the use of the dust collector, the filter bag can filter the dust and impurities in the flue gas, and the dust and impurities in the flue gas will fall into the hopper. When there are a lot of dust and impurities in the hopper, the dust and impurities are easy to accumulate on the inner wall surface of the hopper and are not easy to fall off. It is inconvenient for personnel to clean the inner wall of the hopper outside the dust collector. At the same time, due to the exhaust, the sealing between the cover plate on the top of the dust collector and the filter box is poor, which easily causes moisture to enter the filter box, thereby affecting the dust removal efficiency.

Among them, the shape of the filter box can be a cylinder, a cuboid, a cube, etc., and the discharge hopper contains a funnel-shaped structure, such as a conical structure, a quadrangular pyramid structure, etc.; in addition, the structure of the rotating rod can be set in a form that can be connected to an array of scrapers; the structure or shape of the scraper matches the inclined inner wall of the discharge hopper, and is not pressed tightly against the inclined inner wall of the discharge hopper, leaving a certain gap.

[0008] Furthermore, the blowing pipe of the blower is a rotating blowing pipe. Specifically, the rotating blowing pipe rotates around the blowing pipe as an axis, and the rotation angle is less than 180°.

[0009] Furthermore, the shape of the scraper matches the inclined inner wall of the discharge hopper, and a gap is left between the scraper and the inclined inner wall of the discharge hopper. Preferably, the scraper is a wedge-shaped scraper or a triangular prism scraper, wherein the thinner side is close to the inner wall of the discharge port.

[0010] Furthermore, the rotating rod is fixedly connected or movably connected to the scraper, wherein the fixed connection method is preferably welding, bonding or mechanical structure connection, and the movably connected method is preferably connected through elastic parts.

[0011] Furthermore, the connecting rod is an inverted L-shaped connecting rod.

[0012] Furthermore, the motor and the rotating rod are connected via a belt.

[0013] Furthermore, an annular guide groove is provided at the bottom of the connecting plate, and a guide block is fixedly connected to the surface of the rotating rod near the guide groove.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The bag dust collector can effectively filter the dust and impurities in the flue gas, so that the filtered flue gas is not easy to pollute the outside air. When dust accumulates on the inner wall of the discharge hopper, turn on the motor. The motor can drive the belt to rotate, and the belt rotation can drive the rotating rod to rotate. The rotation of the rotating rod also drives the guide block to rotate. When the rotating rod rotates, it can drive the scraper and the inverted L-shaped connecting rod to rotate. When the scraper rotates, it can move along the inner wall surface of the discharge hopper. At this time, the scraper can scrape the dust and impurities on the inner wall surface of the discharge hopper. At the same time, the rotation of the inverted L-shaped connecting rod can prevent the discharge port at the bottom of the discharge hopper from being blocked. Through this simple and convenient method, the dust and impurities on the inner wall surface of the discharge hopper can be cleaned regularly.

[0018] 2. Due to the exhaust, the sealing between the cover plate and the filter box at the top of the dust collector is poor, which easily leads to moisture entering the filter box, thus affecting the dust removal efficiency. When the block of the utility model moves, the spring can be compressed. When the spring is compressed to a specified degree, the latch can be inserted through the block through the latch hole. At this time, the cover plate can be covered on the top of the filter box. When the cover plate and the filter box are completely docked, the plug-in block can be plugged into the inside of the fixed block, and the sealing ring is tightly attached to the inside of the filter box. At this time, the latch can be taken out from the inside of the block. When the block is reset, its end can be plugged into the inside of the plug-in block, thereby limiting the cover plate. At the same time, the block can drive the rubber plate to be tightly attached to the outside of the filter box. The sealing between the cover plate and the filter box can be improved by limiting the sealing ring and the cover plate, so that external moisture is not easy to enter the inside of the filter box, avoiding the dust removal efficiency of the dust collector from being affected.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Reference Figure 1-3The utility model provides a bag dust collector, comprising: a filter box 1, a discharge hopper 2, an air inlet pipe 3, a filter bag 4, a blower 5, an air blower 6, a cover plate 7, a connecting plate 8 and a motor 9, the blower 5 comprising a blower pipe 51 and an air blowing mechanism 52, the bottom end of the filter box 1 is welded with the discharge hopper 2, the outside of the filter box 1 is connected with the air inlet pipe 3, the inside of the filter box 1 is installed with the filter bag 4, the top of the filter bag 4 is provided with a blower pipe 51, the outside of the filter box 1 is installed with the air blower 6, wherein the air inlet pipe 3 and the air blower 6 are connected with the inside of the filter box 1, and the top of the filter box 1 is installed with a A connecting plate 8 is welded to the inner wall of the bottom of the cover plate 7 and the filter box body 1, a motor 9 is installed on the upper surface of the connecting plate 8, a guide groove 10 is opened at the bottom of the connecting plate 8, a rotating rod 11 is connected to the connecting plate 8 through a bearing, a belt 12 is connected between the end of the rotating rod 11 and the output end of the motor 9, a guide block 13 is welded to the surface of the rotating rod 11 close to the guide groove 10, a scraper 14 and an inverted L-shaped connecting rod 15 are respectively welded to the outside of the rotating rod 11, a rotating structure is formed between the rotating rod 11 and the connecting plate 8, and a rotating sliding structure is formed between the guide block 13 and the connecting plate 8 through the guide groove 10.

[0026] In specific implementation, the flue gas enters the filter box 1 from the air inlet pipe 3, is filtered by the filter bag 4, and the filtered flue gas is discharged from the dust collector by the air outlet fan 6. The dust collector can effectively filter the dust and impurities in the flue gas, so that the filtered flue gas is not easy to pollute the outside air. After being used for a period of time, the filter bag 4 is sprayed with dust by the injector 5 to remove the dust and impurities remaining on the surface of the filter bag 4, so that the filter bag 4 maintains a good filtering effect. The blown dust and impurities fall into the discharge hopper 2, and the dust is discharged from the bottom outlet of the discharge hopper 2 through the inner wall of the discharge hopper 2 with a certain inclination angle. However, the inner wall of the discharge hopper 2 is easy to accumulate dust and is not easy to fall. At this time, the motor 9 can be started. When the motor 9 is running, it can drive the belt 12 to rotate, further drive the rotating rod 11 to rotate, and at the same time drive the guide block 13 to rotate. The guide block 13 rotates and moves at the bottom of the connecting plate 8 through the guide groove 10. When the rotating rod 11 rotates, the scraper 14 and the inverted L-shaped connecting rod 15 can be driven to rotate. When the scraper 14 rotates, it can move along the inner wall surface of the discharge hopper 2, and can scrape the dust and impurities on the inner wall surface of the discharge hopper 2, so that the dust and impurities on the inner surface of the discharge hopper 2 can be scraped off. At the same time, the inverted L-shaped connecting rod 15 rotates to prevent the discharge port at the bottom of the discharge hopper 2 from being blocked. The guide block 13 rotates in the guide groove 10 at the bottom of the connecting plate 8, which stabilizes the rotation of the rotating rod 11. In addition, when the motor 9 is working, it will vibrate, which will link the connecting plate 8 to vibrate, so as to achieve the effect of shaking off the dust and impurities accumulated on the connecting plate. In addition, the blowing pipe 51 can be rotated to spray, so as to achieve full dust removal of the filter bag, and the blowing time can be appropriately extended, so as to play a certain blowing effect on the dust and impurities accumulated on the connecting plate 8. The connecting plate 8 can be a solid plate or a partially hollow plate, and its size and shape can be determined based on the shape and size of the filter box 1 and the discharge hopper 2, as well as the weight and size of the rotating shaft, motor, etc.

[0027] Reference Figure 1 , Figure 2 and Figure 3 It can be seen that, through this simple and convenient dust collector and use method, the dust and impurities accumulated on the inner wall surface of the discharge hopper 2 can be cleaned regularly.

[0028] Reference Figure 1 , Figure 2 and Figure 4It can be seen that the sealing structure includes a plug-in block 16, a sealing ring 17, a fixing block 18, a spring 19, a clamping block 20, a rubber plate 21 and a latch 22. The plug-in block 16 is welded to the bottom of the cover plate 7. The plug-in block 16 has a groove on one side close to the filter box 1. A sealing ring 17 is also bonded to the bottom of the cover plate 7. The sealing ring 17 is located between the plug-in block 16 and the edge of the cover plate 7. The inner wall of the filter box 1 is welded with a fixing block 18. The fixing block 18 is directly opposite to the plug-in block 16. A groove is provided at the position of the fixing block 18, a spring 19 is connected to the inside of the fixing block 18, a clamping block 20 is connected to the other end of the spring 19, the clamping block 20 passes through the filter box 1 and a rubber plate 21 is installed on the outside of the filter box 1, a latch hole 23 is provided on the clamping block 20, the latch hole 23 is located between the spring 19 and the rubber plate 21, a latch 22 is connected to the outside of the filter box 1 through a rope, and a plug-in structure is formed between the latch 22 and the clamping block 20 through the latch hole 23.

[0029] During specific implementation, the cover plate 7 on the top of the dust collector and the filter box 1 may have poor sealing due to exhaust, which may easily lead to moisture entering the filter box 1, thereby affecting the dust removal efficiency. For this reason, a plurality of symmetrical groups of the above-mentioned sealing structures can be set on the cover plate 7 and the filter box 1 of the dust collector, and the symmetrical groups of card blocks 20 are pulled. When the card blocks 20 move, the spring 19 can be compressed. When the spring 19 is compressed to a specified degree, the latch 22 can be inserted into the latch hole 23 to penetrate the card block 20, so that the card block 20 will not be reset. The cover plate 7 can be covered on the top of the filter box 1. When the cover plate 7 is completely connected to the filter box 1, the plug-in block 16 can be plugged into the groove of the fixing block 18, and the sealing ring 17 is in close contact with the inner wall of the filter box 1. At this time, the latch 22 can be taken out from the latch hole 23 of the block 20. When the latch 22 no longer restricts the block 20, the block 20 can be reset by the spring 19. When the block 20 is reset, its end can be plugged into the groove of the plug-in block 16, thereby limiting the cover plate 7. At the same time, the block 20 can drive the rubber plate 21 to be in close contact with the outside of the filter box 1.

[0030] Reference Figure 1 , Figure 2 and Figure 4 It can be seen that the sealing between the cover plate 7 and the filter box 1 can be improved by limiting the cover plate 7 and sealing the sealing ring 17, so that external moisture is not easy to enter the filter box 1, avoiding that the dust removal efficiency of the dust collector is affected.
