Abstract
Description
Technical Field
[0001] This utility model relates to the field of baghouse dust collectors, and in particular to a structure for unclogging the ash hopper of a baghouse dust collector. Background Technology
[0002] Baghouse dust collectors are a type of air purification equipment commonly used in industrial environments to remove particulate matter and dust from the air in order to maintain clean air and a safe production environment. Baghouse dust collectors are often equipped with ash hoppers to store particulate matter and dust before discharging them in a unified manner.
[0003] For example, CN214715240U discloses a bidirectional jet-blowing cleaning structure for the lower ash inlet of a bag filter dust collector. It includes an upper jet pipe and a lower jet pipe located outside the lower ash inlet of the dust collector. Both the upper and lower jet pipes are annular and connected to air supply lines. The upper jet pipe has multiple downward-sloping nozzles evenly distributed along its circumference, and the lower jet pipe has multiple upward-sloping nozzles evenly distributed along its circumference. The downward-sloping and upward-sloping nozzles are staggered. An expansion throat is located at the lower ash inlet of the dust collector, between the upper and lower jet pipes. The outlets of the downward-sloping and upward-sloping nozzles are flush with the inner wall of the expansion throat. In this invention, the upper and lower jet pipes can spray compressed air from different directions onto the accumulated dust, breaking up the material bridge formed at the lower ash inlet of the dust collector, allowing the dust to be smoothly discharged from the bag filter dust collector through the lower ash inlet, eliminating the need for manual cleaning during downtime.
[0004] Dust can be cleaned by simply spraying compressed air, but stubborn dust clumps can easily accumulate inside the ash hopper. These clumps are difficult to clean by air jets, and over time they will still cause blockages in the ash hopper, affecting its normal material discharge efficiency. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a clogging structure for the dust hopper of a bag filter, which solves the problems mentioned in the background.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a dust collector hopper unclogging structure, including a dust hopper, a folded plate fixedly connected to the right side of the dust hopper, and a vibration striking mechanism provided on the right side of the dust hopper, the vibration striking mechanism including a wave plate, the wave plate being fixedly connected to the bottom of the folded plate, and the wave plate being obliquely arranged.
[0007] As a further technical solution of this utility model, a fixing plate is fixedly connected to the right side of the ash hopper, an electric push rod is fixedly connected to the bottom of the fixing plate, and a square plate is fixedly connected to the bottom of the electric push rod.
[0008] As a further technical solution of this utility model, a striking rod is movably inserted through the interior of the square plate and extends to its left and right sides, with the right end of the striking rod contacting the wave plate.
[0009] As a further technical solution of this utility model, a ring is fixedly connected to the outer wall of the striking rod, and a first spring is sleeved on the outer wall of the striking rod. The two ends of the first spring are located between the square plate and the ring. When the electric push rod is activated, it drives the square plate at its bottom to move downward, and the square plate drives the striking rod inside it to move downward together. Since the right end of the striking rod is always in contact with the surface of the inclined fixed corrugated plate, during the downward movement, the wavy inclined surface of the corrugated plate will force the striking rod to overcome the elastic force of the first spring and generate a horizontal displacement to the left. When the electric push rod retracts and drives the square plate to move upward, the first spring releases energy, pushes the ring and the striking rod to reset to the right, and then presses against the surface of the corrugated plate again. The continuous reciprocating extension and retraction of the electric push rod causes the striking rod to repeatedly move left and right laterally, and its left end periodically strikes the side wall of the ash hopper, thereby generating strong mechanical vibration and effectively loosening the dust clumps adhering to the inner wall of the ash hopper.
[0010] As a further technical solution of this utility model, the ash hopper is provided with a dynamic spraying mechanism. The dynamic spraying mechanism includes a chute. The chute is opened inside the ash hopper. Two sliders are slidably connected inside the chute. A second spring is fixedly connected between the two sliders and the chute.
[0011] As a further technical solution of this utility model, the bottom of the wave plate is fixedly connected to a compressed air tank and a jet pipe is provided at the bottom. The end of the jet pipe away from the compressed air tank is located inside the ash hopper, and the slider is sleeved on the outer wall of the jet pipe.
[0012] As a further technical solution of this utility model, the bottoms of the two sliders are respectively fixedly connected to abutment plates, and the bottom of the square plate is fixedly connected to a conical abutment block. The conical abutment block contacts the two abutment plates. The compressed air tank continuously supplies compressed air to the jet pipe, and the airflow is ejected from the outlet of the jet pipe, directly impacting the ash accumulated in the ash hopper. When the square plate moves downward under the drive of the vibration and tapping mechanism, the conical abutment block at its bottom descends accordingly. The conical surface squeezes the abutment plates on both sides, forcing the two sliders to overcome the elastic force of the second spring and separate to both sides of the slide groove, thereby driving the jet pipe to move to one side. When the square plate moves upward, the conical abutment block rises, and its pressure on the abutment plates disappears. At this time, the second spring pulls the two sliders and the jet pipe back to the center. In this way, the jet pipe performs a reciprocating horizontal scanning motion inside the ash hopper according to the working rhythm of the vibration and tapping mechanism, thereby expanding the spray coverage of compressed air and realizing dynamic unblocking without dead angles.
[0013] This utility model provides a clogging removal structure for the dust hopper of a bag filter, which has the following advantages compared with the prior art: 1. This design presents a dust collector hopper cleaning structure. An electric push rod drives a square plate and a striking rod to move along a wave-shaped plate positioned at a specific angle. This causes the striking rod to generate regular reciprocating lateral vibrations that directly act on the sidewall of the dust hopper. This method effectively transmits mechanical vibration force, generating continuous and multi-directional vibration, which can effectively break up firmly adhered dust clumps on the inner wall of the dust hopper. This solves the problem of insufficient impact force and difficulty in handling sticky, wet clumps caused by a single air-blowing method.
[0014] 2. This design features a dust collector hopper cleaning structure where the air jet pipe is not fixed but connected to a sliding groove via a slider and spring, enabling it to move adaptively. During vibration and impact, the conical contact block periodically and alternately presses two contact plates, driving the air jet pipe and slider to reciprocate within a certain range within the sliding groove. This allows for dynamic changes in the compressed air injection range, significantly expanding the coverage area of the airflow impact, effectively eliminating dead zones present with fixed jet cleaning, and achieving more comprehensive and uniform cleaning of the dust hopper's interior.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-4 This utility model provides a technical solution for a bag filter dust collector hopper unclogging structure: A bag filter dust collector hopper unclogging structure includes a dust hopper 1, a folded plate 2 fixedly connected to the right side of the dust hopper 1, a vibration striking mechanism 3 provided on the right side of the dust hopper 1, the vibration striking mechanism 3 including a corrugated plate 311, the corrugated plate 311 fixedly connected to the bottom of the folded plate 2, the corrugated plate 311 being obliquely arranged, a fixing plate 312 fixedly connected to the right side of the dust hopper 1, an electric push rod 313 fixedly connected to the bottom of the fixing plate 312, the bottom of the electric push rod 313 being fixedly... A square plate 314 is fixedly connected, and a striking rod 315 is movably passed through the inside of the square plate 314 and extends to the left and right sides. The right end of the striking rod 315 contacts the wave plate 311. A ring 316 is fixedly connected to the outer wall of the striking rod 315. A first spring 317 is sleeved on the outer wall of the striking rod 315. The two ends of the first spring 317 are located between the square plate 314 and the ring 316. When the electric push rod 313 is activated, it drives the square plate 314 at its bottom to move downward. The square plate 314 drives the striking rod 315 inside it to move downward together. Since the right end of the striking rod 315 is always in contact with the surface of the inclined fixed corrugated plate 311, during the downward movement, the wavy inclined surface of the corrugated plate 311 will force the striking rod 315 to overcome the elastic force of the first spring 317 and generate a horizontal displacement to the left. When the electric push rod 313 retracts and drives the square plate 314 to move upward, the first spring 317 releases energy, pushing the ring 316 and the striking rod 315 to reset to the right and to press against the surface of the corrugated plate 311 again. The continuous reciprocating extension and retraction of the electric push rod 313 causes the striking rod 315 to repeatedly move left and right laterally, and its left end periodically strikes the side wall of the ash hopper 1, thereby generating strong mechanical vibration and effectively loosening the dust blocks adhering to the inner wall of the ash hopper 1.
[0019] like Figure 4As shown, a dynamic spraying mechanism 4 is installed inside the ash hopper 1. The dynamic spraying mechanism 4 includes a slide 411, which is opened inside the ash hopper 1. Two sliders 412 are slidably connected inside the slide 411. Second springs 413 are fixedly connected between the two sliders 412 and the slide 411. The bottom of the wave plate 311 is fixedly connected to the bottom of the compressed air tank 414, and an air jet pipe 415 is provided. The end of the air jet pipe 415 away from the compressed air tank 414 is located inside the ash hopper 1. The sliders 412 are sleeved... Located on the outer wall of the jet pipe 415, two sliders 412 are fixedly connected to their bottoms with contact plates 416, and a square plate 314 is fixedly connected to its bottom with a conical contact block 417. The conical contact block 417 contacts the two contact plates 416. The compressed air tank 414 continuously supplies compressed air to the jet pipe 415, and the airflow is ejected from the outlet of the jet pipe 415, directly impacting the ash accumulated in the ash hopper 1. When the square plate 314 moves downward under the drive of the vibration and striking mechanism 3, the conical contact block 417 at its bottom also descends. The conical surface squeezes the contact plates 416 on both sides, forcing the two sliders 412 to overcome the elastic force of the second spring 413 and separate to both sides of the slide groove 411, thereby driving the jet pipe 415 to move to one side. When the square plate 314 moves upward, the conical contact block 417 rises, and its pressure on the contact plates 416 disappears. At this time, the second spring 413 pulls the two sliders 412 and the jet pipe 415 back to the center. Thus, the jet pipe 415 performs a reciprocating lateral scanning motion inside the ash hopper 1 in accordance with the working rhythm of the vibration knocking mechanism 3, thereby expanding the spray coverage of compressed air and achieving dynamic unblocking without dead angles.
[0020] The working principle of this utility model is as follows: The electric push rod 313 is activated, driving the square plate 314 at its bottom to move downwards. The square plate 314 then moves the striking rod 315 inside it downwards as well. Since the right end of the striking rod 315 is always in contact with the surface of the inclined wave plate 311, during the downward movement, the wave-shaped inclined surface of the wave plate 311 forces the striking rod 315 to overcome the elastic force of the first spring 317 and generate a horizontal displacement to the left. When the electric push rod 313 retracts, driving the square plate 314 to move upwards, the first spring 317 releases energy, pushing the ring 316 and the striking rod 315 to reset to the right and to press against the surface of the wave plate 311 again. The continuous reciprocating extension and retraction of the electric push rod 313 causes the striking rod 315 to repeatedly move laterally left and right, and its left end periodically strikes the side wall of the ash hopper 1, thereby generating strong mechanical vibration and effectively loosening the dust clumps adhering to the inner wall of the ash hopper 1. Compressed air tank 414 continuously supplies compressed air to jet pipe 415. The airflow is ejected from the outlet of jet pipe 415, directly impacting the accumulated ash in ash hopper 1. When square plate 314 moves downward under the drive of vibration and tapping mechanism 3, the conical contact block 417 at its bottom descends accordingly. The conical surface squeezes the contact plates 416 on both sides, forcing the two sliders 412 to overcome the elastic force of the second spring 413 and separate to both sides of the slide groove 411, thereby driving jet pipe 415 to move to one side. When square plate 314 moves upward, conical contact block 417 rises, and its pressure on contact plate 416 disappears. At this time, second spring 413 pulls the two sliders 412 and jet pipe 415 back to the center. In this way, jet pipe 415 performs reciprocating lateral scanning motion inside ash hopper 1 in accordance with the working rhythm of vibration and tapping mechanism 3, thereby expanding the spray coverage of compressed air and realizing dynamic unblocking without dead angles.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
