Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal equipment, in particular to a bag dust removal box. Background Art

[0002] Bag filters are used to capture fine, dry dust. Made of textile filter cloth or non-woven felt, the bags utilize the fabric's filtering properties to filter dust-laden air. As dust-laden air blows toward the bag, the dust particles are intercepted by the bags. The trapped dust either falls into the hopper below or adheres to the outer surface of the bags.

[0003] As bag-type dust collectors are used for extended periods of time, the amount of dust adhering to the outer surface of the bags continues to increase. This affects the dust removal effect, and the dust adhering to the bags needs to be cleaned. Currently, the most commonly used bag-type dust collector is a pulse-type dust collector. For example, Chinese patent document CN216320614U discloses a bag-type pulse dust collector, which is provided with a blowing assembly. The blowing assembly includes an air bag mounted on the side wall of the dust removal box, an air blowing pipe connected to the air bag, and an electromagnetic pulse valve mounted on the air blowing pipe. The air blowing pipe extends into the dust removal box and is located above the fixed plate. Multiple nozzles are installed on the corresponding through-holes of the air blowing pipe. When it is necessary to clean the dust adhering to the outside of the filter bag, the dust-laden gas is stopped from entering the dust collector and the blowing assembly is activated. At this point, the gas in the air bag is sprayed into the filter bag through the nozzle in a pulsed blowing manner. The filter bag suddenly expands, thereby shaking off the dust on its outer surface, and ultimately causing the dust to fall into the ash hopper. The pulse dust collector has a better dust removal effect on small-sized bags. For large-sized bags, it is necessary to equip them with enough gas and spray it into the bags at a fast enough speed to make the bags expand instantly. This method undoubtedly increases the gas consumption. In addition, in this method, due to the vibration caused by expansion, the vibration effect at the end of the bag farther from the nozzle is poor, which in turn affects the dust removal effect of the bag. Utility Model Content

[0004] The technical problem to be solved by the present invention is: in the existing technology, the gas consumption of pulse-type air blowing dust removal is large, and the vibration effect of the bag needs to be improved. Based on this, the present invention provides a bag dust removal box that does not require air source consumption and can ensure that the bag is fully vibrated to improve the dust removal effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a bag-type dust collector box, comprising a box body and a bag-type dust collector vertically placed in the box body, a baffle with a through hole horizontally placed in the box body, the bag-type dust collector comprising a frame and a bag fixedly sleeved outside the frame, the frame comprising a plurality of fixing rings arranged in sequence along the longitudinal direction and a plurality of fixing rods vertically connected between the fixing rings, the fixing ring located at the top is fixedly connected to the baffle corresponding to the through hole, a movable rod is provided on the side wall of the box body so as to be slidable back and forth in the horizontal direction, a vibrating ring is fixedly provided on the movable rod, the vibrating ring is sleeved on the outside of the bag, and a driving member for driving the movable rod to move is provided on the outer wall of the box body, and when the vibrating ring moves, it can collide with the fixed rods on opposite sides of the bag-type dust collector in sequence.

[0006] Furthermore, the cloth bag is in a tight state and fits tightly against the fixing rod.

[0007] Furthermore, the fixed ring is a circular ring structure, the movable rod moves along the radial direction of the cloth bag, and the fixed rod includes a first fixed rod and a second fixed rod arranged opposite to each other. The vertical line segment between the first fixed rod and the second fixed rod is arranged along the radial direction of the cloth bag and is parallel to the moving direction of the movable rod.

[0008] Furthermore, guide sleeves are fixedly connected to the two opposite side walls of the box, the vibration ring is fixedly installed in the middle of the movable rod, one end of the movable rod can slide through the guide sleeve on one side, and the other end of the movable rod can be slidably arranged in the guide sleeve on the other side.

[0009] Furthermore, a grille is horizontally fixedly connected to the box body, and the fixing ring located at the bottom is fixedly connected to the grille.

[0010] Furthermore, two vibration rings are provided on the outside of each cloth bag in a vertical direction, and the movement directions of the two vibration rings are opposite.

[0011] Furthermore, the driving member is a cylinder installed on the box body, the cylinder body of the cylinder is fixedly connected to the outer side wall of the box body, and the protruding end of the cylinder is fixedly connected to the movable rod.

[0012] Furthermore, each of the movable rods is correspondingly connected to one of the cylinders.

[0013] Furthermore, the movable rods on the two vibration rings that are jointly sleeved on the outside of the same cloth bag are both connected to the protruding ends of the same cylinder.

[0014] The beneficial effect of the utility model is that the bag dust removal box provided by the utility model adopts a vibrating ring to reciprocately collide with the frame, thereby driving the entire bag to vibrate, and then shaking off the dust attached to the bag. Compared with the traditional pulse-type blowing dust removal method, the bag vibrates more thoroughly, avoiding the situation where insufficient air flow causes the vibration effect of the end of the bag away from the nozzle to be poor, thereby greatly improving the dust removal effect of the bag.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0022] See also Figure 1-Figure 4The present invention provides a bag dust collector box, comprising a box body 1 and a plurality of bag dust collectors 2 vertically arranged in the box body 1. In this embodiment, there are four bag dust collectors 2. A baffle 11 with a through hole 111 is horizontally placed in the box body 1. The bag dust collector 2 comprises a skeleton 21 and a bag 22 fixedly sleeved on the outside of the skeleton 21. The skeleton 21 comprises a plurality of fixing rings 211 arranged in sequence along the longitudinal direction and a plurality of fixing rods 212 vertically connected between the fixing rings 211. The fixing ring 211 located at the top is fixedly connected to the baffle 11 corresponding to the through hole 111. A movable rod 3 is connected to the side wall of the box body 1 so as to be slidable back and forth in the horizontal direction. A vibration ring 4 is fixedly connected to the movable rod 3. The vibration ring 4 is sleeved on the outside of the bag 22. A driving member 5 for driving the movable rod 3 to move is installed on the outer wall of the box body 1. When the vibration ring 4 moves, it can collide with the fixed rods 212 on opposite sides of the bag dust collector 2 in sequence.

[0023] In addition, an ash hopper 6 is connected to the box body 1 below the bag dust collector 2, an air inlet pipe 7 is connected to the side wall of the box body 1 between the bag dust collector 2 and the ash hopper 6, and an air outlet pipe 8 is connected to the top of the box body 1 above the baffle 11.

[0024] During use, dust-laden gas enters the housing 1 through the air inlet pipe 7. The dust-laden gas flows upward, and the dust in the gas is intercepted on the outside of the bag 22 by the blocking effect of the bag filter 2. The gas that passes through the bag 22 eventually flows out of the air outlet pipe 8 through the through hole 111, thereby filtering the dust-laden gas. Part of the dust intercepted by the bag 22 falls directly into the ash hopper 6 below, and the rest adheres to the outer surface of the bag 22. When too much dust accumulates on the bag 22 and affects the filtering effect, the dust on the bag 22 needs to be cleaned. At this time, the driving member 5 is started to drive the movable rod 3 to move, thereby driving the vibrating ring 4 to move back and forth. During the reciprocating process, the vibrating ring 4 will collide with the fixed rods 212 on opposite sides of the bag filter 2 in turn. After the collision, the fixed rods 212 will vibrate, thereby driving the bag 22 on it to vibrate, so as to shake off the dust attached to the bag 22.

[0025] In this embodiment, the frame 21 is made of stainless steel, and the cloth bag 22 is fixed to the frame 21 by gluing or using cable ties. The cloth bag 22 is kept taut and closely adheres to the fixing rod 212, ensuring that when the fixing rod 212 vibrates, the cloth bag 22 also vibrates strongly. The fixing ring 211 strengthens the structural strength of the fixing rod 212 and effectively prevents it from easily deforming. In a preferred embodiment, the fixing ring 211 is welded to the fixing rod 212.

[0026] As a preferred embodiment, the fixed ring 211 is a circular ring structure, the bag 22 is a cylindrical structure with an opening at the upper end, the movable rod 3 moves along the radial direction of the bag 22, and the fixed rod 212 includes a first fixed rod 2121 and a second fixed rod 2122 arranged opposite each other. The vertical segment between the first fixed rod 212 and the second fixed rod 2122 is arranged along the radial direction of the bag 22 and is parallel to the moving direction of the movable rod 3. In this way, when the movable rod 3 drives the vibration ring 4 to move back and forth, it can ensure that the opposite sides of the vibration ring 4 can collide with the first fixed rod 2121 and the second fixed rod 2122 in sequence, thereby causing the bag dust collector 2 to vibrate as a whole. In addition, vibrating the opposite sides of the bag dust collector 2 can fully shake off the dust.

[0027] As a preferred embodiment, guide sleeves 12 are fixedly connected to two opposing side walls of the housing 1, and the vibration ring 4 is fixedly mounted in the middle of the movable rod 3. One end of the movable rod 3 slidably passes through the guide sleeve 12 on one side, and the other end of the movable rod 3 slidably resides within the guide sleeve 12 on the other side. By providing guide sleeves 12 on both sides, the movable rod 3 is spanned between the two guide sleeves 12, guiding the movable rod 3 and ensuring the stability of the movement of the movable rod 3. Furthermore, a seal is provided between the guide sleeve 12 and the movable rod 3 to prevent gas leakage. The seal is made of rubber or silicone, which is not limited herein.

[0028] In this embodiment, a grille 9 is fixedly mounted horizontally within the housing 1, with a fixing ring 211 at the bottom being fixedly connected to the grille 9. The grille 9 secures the lower end of the bag-type dust collector 2. Together with the baffle 11 securing the upper end of the bag-type dust collector 2, the grille 9 is stably fixed within the housing 1, preventing it from detaching from the housing 1 when impacted by the vibrating ring 4. Furthermore, the holes in the grille 9 ensure that flue gas can flow to the bag-type dust collector 2.

[0029] As a preferred embodiment, two vibrating rings 4 are vertically mounted on the exterior of each bag 22, with the two vibrating rings 4 moving in opposite directions. During operation, one side of the upper vibrating ring 4 collides with the first fixing rod 2121, while the other side of the lower vibrating ring 4 collides with the second fixing rod 2122. This ensures that both sides of the same bag 22 are impacted by the vibrating rings 4, ensuring thorough cleaning.

[0030] The driving member 5 is a cylinder mounted on the housing 1. Specifically, the cylinder body is fixedly connected to the outer wall of the housing 1, and the extended end of the cylinder is fixedly connected to the movable rod 3. In this embodiment, each movable rod 3 is connected to a corresponding cylinder. In this way, for the two vibrating rings 4 that are co-mounted outside the same cloth bag 22, the user can achieve the purpose of achieving the purpose of the two vibrating rings 4 moving in opposite directions by controlling the extension direction of the two cylinders separately.

[0031] Of course, in other embodiments not shown, the two vibration rings 4 that are jointly mounted on the outside of the same cloth bag 22 can also be driven by one of the cylinders. At this time, the movable rods 3 on the two vibration rings 4 are both connected to the protruding ends of the same cylinder. At this time, the two vibration rings 4 have the same moving direction. When working, the two vibration rings 4 arranged above and below collide with the same side of the cloth bag 22 together, which can also achieve the purpose of cleaning by collision.

[0032] It can be understood that in another embodiment not shown, the multiple vibration rings 4 on the multiple bag dust collectors 2 can also be connected to each other through connecting rods. In this case, one driving member 5 can drive multiple vibration rings 4 to move at the same time, thereby greatly reducing the number of driving members 5.

[0033] In this embodiment, a valve (not shown) is installed at the discharge port at the bottom of the ash hopper 6 to control the opening and closing of the discharge port.

[0034] The bag dust collector provided by the present invention adopts a vibration ring 4 to reciprocately collide with the frame 21, thereby driving the entire bag 22 to vibrate, and then shaking off the dust attached to the bag 22. Compared with the traditional pulse-type blowing dust removal method, the bag 22 vibrates more thoroughly, avoiding the situation where insufficient air flow causes the vibration effect of the end of the bag away from the nozzle to be poor, thereby greatly improving the dust removal effect of the bag 22.

[0035] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
